Where can i buy propecia over the counter

Limited clinical benefit generic propecia for sale has been demonstrated for chimeric antigen receptor (CAR) therapy of solid tumors, but coengineering strategies to generate so-called fourth-generation (4G) CAR-T cells are advancing toward overcoming barriers in where can i buy propecia over the counter the tumor microenvironment (TME) for improved responses. In large part due to technical challenges, there are relatively few preclinical CAR therapy studies in immunocompetent, syngeneic tumor-bearing mice. Here, we describe optimized methods for where can i buy propecia over the counter the efficient retroviral transduction and expansion of murine T lymphocytes of a predominantly central memory T cell (TCM cell) phenotype.

We present a bicistronic retroviral vector encoding both a tumor vasculature–targeted CAR and murine interleukin-15 (mIL-15), conferring enhanced effector functions, engraftment, tumor control, and TME reprogramming, including NK cell activation and reduced presence of M2 macrophages. The 4G-CAR-T cells coexpressing mIL-15 were further characterized by up-regulation of the antiapoptotic marker Bcl-2 and lower cell-surface expression of the inhibitory receptor PD-1. Overall, this work introduces robust tools for the development and evaluation of 4G-CAR-T cells in immunocompetent mice, an important step toward the acceleration of effective therapies reaching the clinic where can i buy propecia over the counter.

The adoptive cell transfer (ACT) of ex vivo–expanded T lymphocytes has yielded robust and durable clinical responses against several cancer-types, such as tumor-infiltrating lymphocyte therapy of advanced melanoma (Mardiana et al., 2019). Another approach to ACT involves the redirection of peripheral blood where can i buy propecia over the counter T cells to tumor antigens by engineering them to express a chimeric antigen receptor (CAR) that triggers cellular activation upon tumor antigen binding. CAR-T cell therapy against hematologic malignancies, by targeting the B cell lineage antigens CD19 or the B cell maturation antigen, has proven efficacious in the clinic, and there is optimism that similar success will be achieved for some solid tumors (Geyer and Brentjens, 2016.

Irving et al., 2017). A range of physical (Lanitis et al., 2015) and immunometabolic barriers that can prevent T cell homing, transendothelial migration across tumor blood vessels, engraftment/persistence, and effector function limit the potency of CAR-T cell therapy against where can i buy propecia over the counter solid tumors (Brown et al., 2016. Louis et al., 2011).

Moreover, chronic antigen exposure and a lack of sufficient costimulation in the tumor microenvironment (TME) can cause CAR-T cell exhaustion (Irving et al., 2017). Coengineering of CAR-T cells may help where can i buy propecia over the counter to overcome some of these obstacles (Lanitis et al., 2020). Genetic modifications, for example, can be made to enable better homing and tumor penetration or render CAR-T cells resistant to suppressive mechanisms in the TME (Stromnes et al., 2010).

In addition, CAR-T cells can be armed with secretory molecules or additional receptors to support CAR-T cell activity and/or harness endogenous where can i buy propecia over the counter immunity (Adachi et al., 2018. Pegram et al., 2012). Preclinical evaluation of CAR-T cells has, for the most part, been performed with xenograft tumor models in immunodeficient mice (Lee et al., 2011.

Mardiros et where can i buy propecia over the counter al., 2013. Lanitis et al., 2012). Although this approach can be used to evaluate human CAR-T cell persistence, homing, tumor control, and survival following ACT, critical parameters, including potential toxicity against normal tissues (Tran et al., 2013), and the impact of endogenous immunity on both tumor control and escape are not addressed in such models (Spear et al., 2012.

Avanzi et where can i buy propecia over the counter al., 2018). As varying obstacles must be overcome to enhance CAR-T cell responses against different solid tumor types, comprehensive studies in immunocompetent syngeneic tumor models would enable more accurate screening of T cell engineering strategies and provide important insights into improving coengineering and combinatorial treatment approaches (Lanitis et al., 2020). A key limitation where can i buy propecia over the counter of CAR evaluation in syngeneic models stems from inadequate methodologies for efficient murine T cell transduction and expansion.

Indeed, unless T cells derived from multiple donor spleens are transduced or the engineered T cells are restimulated for further expansion, which among other drawbacks are costly and can promote exhaustion and apoptosis (Bucks et al., 2009), respectively, current protocols yield insufficient numbers of CAR-T cells for ACT studies (Lee et al., 2009). The efficiency of cell-surface expression of second-generation (2G) CARs, comprising the endodomain (ED) of CD3ζ and one costimulatory ED (e.g., CD28 or 4-1BB), generally reaches 40–60% (Kochenderfer et al., 2010. Davila et al., where can i buy propecia over the counter 2013.

Wang et al., 2014. Fu et al., 2013). Although retroviral transduction rates as high as 70–80% for where can i buy propecia over the counter murine T cells have been reported, this was assessed at 2 to 3 d after transduction (Tran et al., 2013.

Kuhn et al., 2019. Kusabuka et where can i buy propecia over the counter al., 2016) and thus may include false positives due to transient expression from nonintegrated vector DNA (i.e., pseudo-transduction. Case et al., 1999, Costello et al., 2000).

Moreover, short-term transduction efficiency is often based on reporter genes like GFP, which may overestimate CAR expression levels (Kusabuka et al., 2016. Kuhn et al., 2019 where can i buy propecia over the counter. Davila et al., 2013).

Finally, while stable retroviral packaging and producer cell lines where can i buy propecia over the counter may enable transduction efficiencies for 2G and third-generation (3G. I.e., a CAR having two or more costimulatory EDs) CARs of >60% (Fu et al., 2013), this is a laborious approach if multiple CAR designs are to be compared (Chinnasamy et al., 2010). Here, we report the development of an efficient and highly reproducible protocol for primary murine T cell retroviral transduction and expansion, yielding functional murine 2G-CAR-T cells, as well as fourth-generation (4G)-CAR-T cells coengineered to express murine IL-15 (mIL-15) for enhanced in vitro and in vivo function and TME reprogramming.

Overall, our work provides important tools for enabling the systematic evaluation of 4G-CAR-T where can i buy propecia over the counter cells in immunocompetent, syngeneic tumor-bearing mice, which we believe is critical for effective therapies reaching the clinic. We sought to optimize murine T cell activation, transduction, and expansion methods for preclinical CAR therapy evaluation in immunocompetent, syngeneic tumor-bearing mice. The final protocol we developed is summarized in Fig.

1 and is described in detail in Materials and methods where can i buy propecia over the counter. We used a 2G-CAR targeting vascular endothelial cell growth factor receptor 2 (VEGFR-2), comprising the well-characterized single-chain variable fragment (scFv) DC101 (Chinnasamy et al., 2010), a CD8α hinge and transmembrane domain, and the murine EDs of CD28 and CD3ζ. The anti-VEGFR-2 CAR retroviral vector where can i buy propecia over the counter is abbreviated as DC101-28z (Fig.

2 A). Because retropropeciaes infect proliferating cells (Kusabuka et al., 2016. Chinnasamy et where can i buy propecia over the counter al., 2010.

Hu et al., 2017), we first compared three commonly used methods for inducing T cell activation. (i) magnetic beads coated with anti-(α) CD3 antibody (Ab) and αCD28 Ab (αCD3/CD28 beads) plus recombinant human IL-2 (hIL-2), (ii) plate-immobilized αCD3 Ab along with soluble αCD28 Ab (αCD3-plate/CD28) plus hIL-2, and (iii) Concanavalin A plus hIL-2 and hIL-7. Stimulation with αCD3/CD28 beads consistently resulted in the highest frequency of CD44+ CD62L− (recently activated, memory), CD25+ or where can i buy propecia over the counter CD69+ (activated), and Ki67+ (proliferating) CD3+ T cells (Fig.

2 B and Fig. S1 A) where can i buy propecia over the counter. We next found that concentration of viral particles through ultracentrifugation yielded higher viral titers (>3 × 107 transducing units/ml.

Fig. 2 C) and enabled significantly higher transduction of primary activated primary murine T cells as compared with unconcentrated retropropecia (Fig where can i buy propecia over the counter. 2 D), reaching a plateau at a multiplicity of (MOI) of 5 (∼80% CAR expression.

Fig. 2 E). A single transduction at 24 h after activation versus transduction at both 24 and 48 h did not affect the efficiency in terms of either percentage of cells transduced or CAR expression level per cell (i.e., mean fluorescence intensity [MFI].

Fig. 2, E and F). We observed, however, that the transduction efficiency at 48 h after activation was inferior to that obtained at 24 h after activation (Fig.

2, E and F). A schema of the T cell activation and transduction approaches compared are depicted in Fig. 2 G.

Finally, we observed highest CAR transduction efficiency in CD3+ lymphocytes activated with αCD3/CD28 beads in the presence of hIL-2 as compared with the other aforementioned activation methods (Fig. 2, H and I). Similar results were observed for CD8+ T cells, while for CD4+ T cells, the percentage CAR expression was the same for both αCD3/CD28-bead and αCD3-plate/CD28 activation (Fig.

S1 B). Thus, αCD3/CD28-bead activation was used for all further experiments. Notably, we also investigated concentrated lentiviral transduction of αCD3/CD28-bead–activated murine T cells using the same anti-VEGFR-2 CAR, and consistent with another study (Kerkar et al., 2011), we obtained very low transduction efficiency (∼10%, data not shown).

While long-term T cell culture in IL-2 drives terminal differentiation, the common γ-chain cytokines IL-7 and IL-15 have been reported to promote a central memory T cell (TCM cell) phenotype enabling superior persistence and in vivo tumor control upon ACT (Klebanoff et al., 2005). Thus, we next compared the expansion and functional properties of transduced murine CAR-T cells cultured in hIL-2 alone versus hIL-2 for the first 3 days, followed by hIL-7/IL-15 for the remainder of the culture period (Fig. 3 A).

Both hIL-7 and hIL-15 have been previously demonstrated to act on murine T cells to promote homeostatic proliferation and survival (Eisenman et al., 2002. Nanjappa et al., 2008). As for hIL-2–expanded CAR-T cells (Fig.

2 G), we observed that a single transduction of T cells at 24 h and subsequent expansion in hIL-7/IL-15 was sufficient to achieve a robust and stable transduction efficiency at a MOI as low as 5 (Fig. 3 B). Both culture conditions (hIL-2 alone versus hIL-2 followed by hIL-7/IL-15) enabled high CAR expression on day 7 (Fig.

3 C). On day 9, however, we observed a 26-fold expansion of CAR-T cells exposed to hIL-7/IL-15 as compared with a 9-fold expansion in the presence of hIL-2 alone at a standard concentration of 50 IU/ml (Fig. 3 D).

Moreover, CAR-T cells cultured with hIL-7/IL-15 continued to expand for at least 14 d, while T cells cultured in hIL-2 alone reached a plateau after 1 wk (Fig. 3 D) and exhibited significantly higher levels of cell death starting early in the culture (Fig. 3 E).

We also observed a significantly higher frequency of CD8+ T cells in the hIL-7/IL-15 culture (Fig. 3 F). Finally, transduced T cells expanded with hIL-7/IL-15 had a significantly higher proportion of TCM cells based on cell-surface expression of the hyaluronic acid receptor CD44 and the L-selectin CD62L from day 5 after cytokine addition (Fig.

3, G and H). We sought to evaluate the in vitro reactivity of hIL-2 only versus hIL-7/IL-15 expanded CAR-T cells against target antigen. On day 7 after transduction, we co-cultured CAR-T cells with bEnd3 murine endothelial cells expressing VEGFR-2, as well as with control VEGFR-2− H5V murine endothelial cells (Fig.

3 I). HIL-7/IL-15 expanded CAR-T cells secreted significantly higher levels of IFN-γ, granzyme B, and IL-2 (Fig. 3 J) after bEnd3 target cell recognition in vitro.

Because CAR-T cell expansion with hIL-7/IL-15 results in a higher frequency of CD8+ T cells as compared with hIL-2 only, we next sorted CD8+ T cells on day 7 after transduction and performed a co-culture with bEnd3 and H5V cells. Higher levels of granzyme B, IL-2, and IFN-γ were secreted by hIL-7/IL-15–expanded CD8+ CAR-T cells than hIL-2–expanded ones (Fig. S2).

Moreover, hIL-7/IL-15–expanded CAR-T cells exhibited significantly higher persistence (Fig. 3 K), division rates (Fig. 3 L), and numbers of proliferating CD8+ T cells after 4 d of co-culture (Fig.

3 M). Thus, as compared with hIL-2 alone, CAR-T cell expansion with hIL-7/IL-15 promotes higher viability and favors a TCM cell phenotype, more robust expansion, and superior secretion of cytokines and long-term proliferative capacity upon challenge with target cells. The high transduction efficiency achieved with our optimized method encouraged us to evaluate the coexpression of transgenes and test the impact of additional cargo on CAR-T cell performance.

Given the enhanced functional properties of CAR-T cells exposed to hIL-7/IL-15 at 48 h after transduction as opposed to hIL-2 alone, we focused on coengineering T cells to constitutively produce mIL-15. Notably, hIL-15 has been previously demonstrated to significantly improve the antitumor activity of human CAR-T cells targeting glioblastoma (Krenciute et al., 2017). A bicistronic retroviral vector encoding mIL-15 and the DC101 CAR, both driven by the 5′ LTR of the retropropecia (de Felipe et al., 1999) and separated by a self-cleaving 2A peptide sequence (T2A.

Liu et al., 2017), was built to express this 4G-CAR construct (Fig. 4 A). With a single round of transduction at a MOI as low as 5, we achieved a similarly high expression of the 4G- as the 2G-CAR (Fig.

4, B and C), as well as high intracellular expression of mIL-15 (Fig. 4 D). Significant mIL-15 was also detected by ELISA upon lysis of 4G-CAR-T cells (Fig.

4 E), but very low levels of mIL-15 were found in the culture supernatant (data not shown), presumably due to sequestration of the cytokine by cell-surface IL-15 receptor-α (IL-15-Rα), as has been previously observed for human T cells engineered to secrete hIL-15 (Markley and Sadelain, 2010). Our hypothesis was supported by the fact that we detected high levels of soluble mIL-15 in the supernatants of transfected human Phoenix Eco cells (i.e., the retropropecia producer cell line. Fig.

4 F). Moreover, 4G-CAR–transduced C1498 leukemia cells (which do not express IL-15-Rα. Fig.

S3 A) secreted high levels of mIL-15 (Fig. 4, G and H). Finally, we activated both 2G- and 4G-CAR-T cells with cognate antigen and found significant secretion of mIL-15 by the 4G-CAR-T cells (Fig.

4 I), as has similarly been reported in the context of engineered human T cells (Krenciute et al., 2017). We next sought to investigate the impact of mIL-15 coexpression on CAR-T cell signaling and phenotype. In the absence of exogenous cytokine in the culture supernatant, we observed elevated pSTAT5 in the 4G- versus 2G-CAR-T cells both in terms of frequency and level per cell (Fig.

4, J and K). We further evaluated IL-15-Rα expression and detected lower levels on 4G-CAR-T cells (Fig. 4, L and M), presumably due to receptor internalization (Dubois et al., 2002) and/or mIL-15 occupancy blocking the Ab binding site.

Subsequently, we assessed expression of the antiapoptotic protein Bcl-2, previously reported to enhance 2G- versus first-generation (1G)–CAR-T cell persistence (Song et al., 2012), and found higher expression levels on days 2 and 5 after transduction for 4G- as compared with 2G-CAR-T cells in the absence of exogenous cytokines (Fig. S3, B and C). In addition, we observed significantly higher frequencies of Ki67+ Bcl-2+ 4G-CAR-T cells on days 2 and 5 after transduction (Fig.

5, A and B). Thus, mIL-15 coexpression appears to augment both CAR-T cell survival and proliferation. We further assessed the phenotype of CAR-T cells in the absence of exogenous cytokines in the culture medium and found that on day 2 following transduction, 2G- and 4G-CAR-T cells displayed no differences in the proportion of naive (CD62Lhigh CD44low), central memory (CM.

CD62Lhigh CD44high) and effector memory (EM. CD62Llow CD44high) T cell phenotype populations. However, by day 5 after transduction, 4G-CAR-T cells had a higher proportion of naive and CM cells and fewer EM cells, as compared with 2G-CAR-T cells (Fig.

5, C and D). Notably, there were significantly lower levels of the inhibitory receptor programmed cell death 1 (PD-1. Both percentage and MFI) on 4G- compared with 2G-CAR-T cells (Fig.

5, E and F). Consistent with the above findings, we observed that in the absence of exogenous cytokine the 4G-CAR-T cells exhibited increased expansion during the first 2 d after transduction as compared with the 2G-CAR-T cells (Fig. 5 G).

Both 2G- and 4G-CAR-T cells began to contract at a similar rate from day 2 after transduction, but there were significantly more 4G- than 2G-CAR-T cells on days 5 and 7 (Fig. 5 G). Finally, we observed higher viability of 4G-CAR-T cells over time (Fig.

5 H). Thus, with our optimized protocol, we achieved a high rate of T cell transduction with retropropecia coexpressing a CAR and mIL-15, and in the absence of exogenous cytokines, these 4G-CAR-T cells exhibit a less differentiated and inhibitory phenotype as well as enhanced expansion and viability in vitro. We next sought to evaluate the expansion of 4G- versus 2G-CAR-T cells in the presence of exogenous hIL-7/IL-15.

We observed continuous expansion of 4G- and 2G-CAR-T cells for 2 wk but at a significantly higher rate for the 4G-CAR-T cells (Fig. 6 A). Viability was similarly high for both over a 10-d period (Fig.

6 B). Notably, 4G-CAR-T cells cultured in hIL-2 demonstrated enhanced expansion at days 5 and 9 as compared with similarly cultured 2G-CAR-T cells (Fig. 6 C).

We subsequently sought to determine if increasing hIL-15 levels in the medium could augment 2G-CAR-T cell expansion. We demonstrated that 2G-CAR-T cells cultured in the presence of increasing concentrations of hIL-15 (while maintaining hIL-7 at 10 ng/ml) achieved significant increases in fold expansion, reaching or surpassing that of 4G-CAR-T cells (cultured in standard 10 ng/ml hIL-15) at day 9 after transduction in the presence of 50 ng/ml or 100 ng/ml hIL-15, respectively (Fig. 6 D and Fig.

S3 D). Notably, increasing the concentration of hIL-15 in the culture medium from 10 to 50 or 100 ng/ml significantly increased the expansion of 4G-CAR-T cells (Fig. 6 E), and the fold expansion of 4G-CAR-T cells was nearly double compared to that of 2G-CAR-T cells (cultured in equivalent increased hIL-15 concentrations) on day 9 after transduction (Fig.

6 E and Fig. S3 D). We next tested the effector capacity of 4G- as compared with 2G-CAR-T cells against target cells.

Significantly higher levels of IL-2 were produced by 4G- than 2G-CAR-T cells upon co-culture with VEGFR-2+ bEnd3 cells at 1 wk after transduction, while neither reacted against VEGFR-2− H5V cells (Fig. 6 F). We further observed mIL-15 secretion by 4G-CAR-T cells only upon co-culture with bEnd3 cells and not H5V cells (Fig.

6 G). In addition, there was significantly higher expansion of 4G- than 2G-CAR-T cells at day 4 after co-culture with bEnd3 cells, and neither expanded upon co-culture with H5V cells (Fig. 6, H and I).

The 4G-CAR-T cells also exhibited significantly higher proliferation (Fig. 6 J) and numbers of dividing CD8+ T cells compared with 2G-CAR- or control T cells at day 4 of the co-culture (Fig. 6, K and L).

The ability of 4G- and 2G-CAR-T cells to induce apoptosis of target cells was equivalent (Fig. 6 M, and N), in accordance with previous evaluation of hIL-15-CAR-T cells (Krenciute et al., 2017). We further tested the 4G- and 2G-CAR-T cells in vivo against subcutaneous B16 melanoma tumors.

Briefly, on day 8 after tumor cell injection, with tumors approaching 20–40 mm3 in volume, CD45.2+ C57BL/6 mice were lymphodepleted by sublethal total body irradiation and subsequently received two intravenous T cell injections (8–9 × 106 CD45.1+ cells at each injection. Fig. 7 A).

In mice treated with control T cells, the tumors grew rapidly, while modest tumor control was observed in mice that received 2G-CAR-T cells, similar to previous reports for this tumor vasculature targeting CAR (Chinnasamy et al., 2010, 2012). Mice treated with 4G-CAR-T cells, however, had significantly attenuated tumor growth (Fig. 7 B).

Ex vivo analysis of transferred CD45.1+ T cells in the blood, spleen, and tumor on day 11 after ACT revealed significantly higher engraftment of 4G- than 2G-CAR-T cells and control T cells (Fig. 7, C–E). In addition, CAR expression levels were higher for 4G- than 2G-CAR-T cells in blood, spleen, and tumor (Fig.

7, C, D, and F). Notably, we observed sustained presence of the mIL-15 transgene in the spleens and tumors of mice treated with 4G-CAR-T cells (Fig. 7, D and F).

Finally, in agreement with our in vitro data, 4G-CAR-T cells expressed significantly higher levels of the antiapoptotic protein Bcl-2 in vivo (Fig. 7 G. Flow cytometry gating strategy shown in Fig.

S4). Thus, mIL-15 coexpression by CAR-T cells enhances not only expansion and in vitro effector functions but also in vivo persistence and tumor control. Finally, we sought to comprehensively evaluate the effect of mIL-15 coexpression on CAR-T cells in vivo and to determine if endogenous immune cells are also impacted.

Following the same ACT strategy as demonstrated above (Fig. 8 A), we observed that 4G-CAR-T cells in the spleen (Fig. 8, B and C) and tumor-draining lymph nodes (Fig.

S5, A and B) exhibited a higher frequency of Ki67 (cellular marker for proliferation) than 2G-CAR-T cells. In the tumor, despite that Ki67 expression levels were similar for both 4G- and 2G-CAR-T cells (Fig. 8, D and E), the 4G-CAR-T cells displayed significantly lower levels of PD-1 (Fig.

8, F and G). Analysis of endogenous immune infiltrate revealed significantly higher coexpression of CD69 and Ki67 by natural killer (NK) cells in 4G- as compared with 2G-CAR-T cell–treated tumors (Fig. 8, H and I).

In addition, in 4G-CAR-T cell–treated mice there were lower levels of tumor-residing M2 (F4/80+ CD206+) macrophages, which are often associated with immunosuppression in the TME (Fig. 8 J, K). Both the activation of NK cells and lower levels of M2 macrophages may contribute to tumor control in the context of 4G-CAR-T cell transfer.

Tumor-residing B cells (CD19+ MHC II+) were not detected (Fig. S5, C and D), and there were no differences in splenic B cell frequency in any of the treated mice (Fig. S5, E and F).

Finally, similar frequencies of tumor-residing dendritic cells (DCs. CD11b− CD11c+) were observed among the control and CAR-T cell–treated mice (Fig. S5, G and H).

The flow cytometry gating strategy for the ex vivo characterization of the different immune cell populations is shown in Fig. S4. Thus, 4G-CAR-T cells coexpressing mIL-15, in addition to conferring enhanced tumor control as compared with 2G-CAR-T cells, also reprogram the TME in favor of protective endogenous immunity.

CAR-T cell therapy has yielded unprecedented clinical responses against some hematological malignancies, but not against epithelial-derived solid tumors (Irving et al., 2017). Rational combinatorial treatments and innovative CAR-T cell coengineering strategies (Lanitis et al., 2020) offer solutions for overcoming obstacles in the solid TME, but these are best evaluated in immunocompetent mice to enable the interplay of the endogenous immune system. In this study, we have presented optimized conditions for murine T cell activation, retroviral transduction, and expansion that allowed us to achieve consistently high and stable transgene expression levels, as well as robust expansion of both 2G- and 4G-CAR-T cells having a predominantly TCM cell phenotype, which is favored for ACT (Melchionda et al., 2005.

Gattinoni et al., 2005. Zhou et al., 2005). We have also elucidated the beneficial impact of mIL-15 coexpression by murine CAR-T cells both in vitro and in vivo.

Retroviral vectors, most commonly derived from the murine stem cell propecia (MSCV), a derivative of the Moloney murine leukemia propecia, have proven to be the most effective approach for stably introducing genes into murine T cells (Kerkar et al., 2011). Lentipropecia, however, has demonstrated poor gene transfer in murine T cells, likely due to impaired completion of reverse transcription and of nuclear import of the viral preintegration complex (Baumann et al., 2004. Tsurutani et al., 2007).

Most examples of efficient murine T cell retroviral transduction are for small and easily expressed reporter genes like GFP (Kurachi et al., 2017. Zhang et al., 2003) or 1G-CARs comprising the CD3ζ endodomain only (Lee et al., 2009). Retropropecia-mediated expression of 2G-CARs has proven less robust both in terms of percentage transduction and expression level per T cell (Kochenderfer et al., 2010.

Davila et al., 2013. Fu et al., 2013). Moreover, the long-term stability of CAR expression by murine T cells has not previously been thoroughly evaluated (Kusabuka et al., 2016.

Kochenderfer et al., 2010). Despite that it is common procedure to concentrate lentipropecia via ultracentrifugation, this is usually not performed for CAR-encoding retropropeciaes. In this study, we demonstrated that retropropecia can be efficiently concentrated, leading to significantly improved CAR transduction efficiencies.

We further observed a correlation between CD8+ T cell activation levels (the highest level was achieved by αCD3/CD28 bead stimulation) and transduction efficiency. Previous studies have presented CAR expression early after transduction (2–3 d. Tran et al., 2013.

Kusabuka et al., 2016. Kochenderfer et al., 2010) and thus cannot distinguish from pseudo-transduction (Case et al., 1999. Costello et al., 2000).

In addition, some studies have applied antibiotic selection for enrichment of CAR-T cells (Kusabuka et al., 2016) or have measured GFP (or other markers) that can overestimate transduction efficiency. Here, we have demonstrated robust, long-term CAR expression in murine T cells by staining with recombinant target antigen and in the absence of any selection/enrichment method. In this study, we have also shown the utility of the common γ-chain cytokines hIL-7/IL-15 for enhanced CAR-T cell expansion and survival, as well as for promoting a TCM cell phenotype and ameliorating effector function.

Others have reported superior tumor control by IL-7/IL-15 than IL-2–expanded T cells (Cha et al., 2010. Gattinoni et al., 2005. Mueller et al., 2008).

It has also been previously demonstrated that exposure of murine T cells to IL-2 can potentiate apoptosis by suppressing the inhibitor of Fas signaling, FLIP (FLICE-inhibitory protein), and enhancing the expression of the proapoptotic molecule Fas ligand (Lenardo, 1991. Refaeli et al., 1998). In contrast, IL-7 and IL-15 inhibit activation-induced cell death, support the proliferation and survival of T cells (Waldmann, 2015.

Jiang et al., 2004. Cha et al., 2010), promote a TCM cell phenotype characterized by longer telomeres, and elevate T cell persistence and antitumor efficacy (Melchionda et al., 2005. Gattinoni et al., 2005.

Zhou et al., 2005. Klebanoff et al., 2004. Le et al., 2009).

Similarly, it has been shown that IL-7 and IL-15 enable enhanced human CAR-T cell effector function upon antigen recognition (Xu et al., 2014. Zhou et al., 2019) and that exogenous IL-15 can expand anti-CD19 CAR-T cells in treated patients by up to 180-fold (Ramanayake et al., 2015). Contradictory reports of lower murine T cell function in vitro following culture in IL-7/IL-15 versus IL-2 alone are presumably due to the method of T cell stimulation used, differences in the concentration of IL-2 used, and the duration of expansion (Cha et al., 2010.

Gattinoni et al., 2005. Mueller et al., 2008). We further showed that our methodologies enable the efficient coexpression of mIL-15 and a CAR (encoded by a bicistronic vector) in murine T cells.

Human CAR-T cells coexpressing hIL-15 as a fusion protein tethered to the cell surface, or in a secreted form, have previously demonstrated enhanced expansion and persistence upon antigen stimulation (both in vitro and in vivo), as well as increased tumor control (Hoyos et al., 2010. Markley and Sadelain, 2010). As such, there are high expectations for clinical efficacy of IL-15–CAR-T cells.

In nonactivated murine 4G-CAR-T cells, we observed very low levels of mIL-15 in the culture supernatant, but upon antigenic stimulation, significantly higher amounts were detected, in line with reports for hIL-15 CAR-T cells (Krenciute et al., 2017. Hoyos et al., 2010). Elevated levels of pSTAT5 in the 4G- versus 2G-CAR-T cells indicated active signaling by cytokine/receptor engagement.

The functional integrity of the coexpressed mIL-15 was further supported by enhanced 4G-CAR-T cell proliferation and survival, possibly due to up-regulation of the antiapoptotic molecule Bcl-2 (Wu et al., 2002. Shenoy et al., 2014). In addition, mIL-15 coexpression promoted a TCM cell phenotype, limited PD-1 up-regulation, and conferred superior effector function upon antigenic challenge.

The culture methods presented herein comprising hIL-7/hIL-15 in the medium permitted efficient murine CAR-T cell expansion, which was significantly reinforced upon mIL-15 coexpression by CAR-T cells. This enabled us to further investigate the efficacy of 4G-CAR-T cells in vivo against B16 melanoma tumors. We observed higher tumor control and persistence of 4G- as compared with the 2G-CAR-T cells and sustained expression of the mIL-15 transgene.

Moreover 4G-CAR-T cells exhibited higher Bcl-2 levels, in line with our in vitro data, suggesting that mIL-15 can render CAR-T cells more resistant to apoptosis in vivo. The coexpression of mIL-15 was also associated with significantly lower up-regulation of PD-1, an inhibitory receptor that can impair T cell function in the TME (Ahmadzadeh et al., 2009). Finally, evaluation of endogenous tumor immune infiltrate revealed a significantly higher frequency of activated (CD69+ Ki67+) NK cells and fewer M2 (F4/80+ CD206+) macrophages upon 4G- versus 2G-CAR-T cell transfer.

As NK cells are associated with delayed melanoma tumor growth (Nath et al., 2019), and M2 macrophages have been shown to contribute to tumor progression and metastasis (Poh and Ernst, 2018), the observed TME remodeling upon 4G-CAR-T cell transfer is favorable for tumor control. Our findings are consistent with prior studies. For example, coadministration of IL-15 with tumor-directed monoclonal antibodies enhanced Ab-dependent cellular cytotoxicity by augmenting both NK cell and macrophage activation (Zhang et al., 2018).

In another study, it was shown that the absence of IL-15 in immunocompetent mice promotes the formation of M2 macrophages (Gillgrass et al., 2014). In summary, we have presented comprehensive and highly reproducible methods for efficient retroviral transduction and robust expansion of murine CAR-T cells endowed with favorable properties for ACT studies in immunocompetent mice. We further demonstrated that coexpression of mIL-15 directly promotes CAR-T cell fitness and function and remodels the TME to favor tumor control.

As it is becoming apparent that endogenous immunity can play a critical role in either suppressing or supporting CAR-T cell function in the TME (Kuhn et al., 2019), comprehensive studies in immunocompetent mice are critical for accelerating the translation of effective CAR therapies to the clinic. The murine brain endothelioma cell line bEnd3, the murine immortalized heart endothelial cell line H5V, and the murine leukemia cell line C1498 were cultured in DMEM-GlutaMAX comprising 4,500 mg/liter glucose and 110 mg/liter sodium pyruvate and supplemented with 10% heat-inactivated FBS (Gibco, Thermo Fisher Scientific), 100 U/ml penicillin, and 100 µg/ml streptomycin sulfate. The melanoma cell line B16-F10 was grown as a monolayer in DMEM-GlutaMAX supplemented with 10% FBS, 100 U/ml of penicillin, and 100 µg/ml streptomycin sulfate.

Cells were passaged twice weekly to maintain them under exponential growth conditions and were routinely tested for mycoplasma contamination. The Phoenix Eco retroviral ecotropic packaging cell line, derived from immortalized normal human embryonic kidney cells, was maintained in RPMI 1640-Glutamax medium supplemented with 10% FBS, 100 U/ml penicillin, and 100 µg/ml streptomycin sulfate. Primary murine T cells were cultured in RPMI 1640-Glutamax medium supplemented with 10% FBS, 100 U/ml penicillin, 100 µg/ml streptomycin sulfate, 1 mM sodium pyruvate, 50 µM β-mercaptoethanol, and 10 mM nonessential amino acids (referred to as murine T cell culture medium).

Murine T cell culture medium was further supplemented with human cytokines as described in the method for T cell expansion. The retroviral vector pMSGV (murine stem cell propecia [MSCV]–based splice-gag vector) comprising the MSCV LTR was used as the backbone for all CAR constructs. A 2G-CAR consisting of the anti-VEGFR-2 scFv, DC101, the CD8α hinge (H), and TM region, followed by the EDs of CD28 and CD3ζ (DC101-28-z), was kindly provided by Dr.

Steven A. Rosenberg (National Cancer Institute, Bethesda, MD. Chinnasamy et al., 2010).

The DC101-28-z CAR was built by PCR amplification of a 362-bp fragment from the 2G construct with the primers. 5′-ACG​CGC​GGC​CGC​AAC​TAC​TAC​CAA​GC-3′ and 5′-ACG​CGT​CGA​CGG​GGC​GGT​ACG​CTG​CAA​AGT​CTC-3′ followed by NotI and SalI digestion of both the PCR product and the parental 2G vector, gel purification, and ligation. To generate the 4G-CAR construct encoding both mIL-15 and the VEGFR-2–directed CAR (mIL-15-T2A-DC101-28-z), a gene-string encoding the murine Igκ leader sequence followed by codon-optimized mIL-15 and T2A, flanked by XhoI and EcoRI restriction sites at the 5′ and 3′ ends, respectively, was synthesized.

The DC101-28-z construct and fragment were then digested (XhoI and EcoRI), gel purified, and ligated together. All genes strings were synthesized by GeneArt AG, and all constructs were fully sequenced by Microsynth AG. High-titer, replication-defective retropropecia was produced and concentrated as depicted in Fig.

1. Briefly, Phoenix Eco cells were seeded at 107 per T-150 tissue culture flask in 35 ml culture medium (Fig. 1 A, 1) 24 h before transfection with 14.4 µg pCL-Eco Retropropecia Packaging Vector and 21.4 µg pMSGV transfer plasmid using Turbofect (Thermo Fisher Scientific.

Fig. 1 A, 2). All plasmids were purified using HiPure Plasmid Filter Maxiprep Kit (Invitrogen, Thermo Fisher Scientific).

For the transfection mixture, a 3:1 ratio of Turbofect/plasmid was prepared in 2 ml Opti-MEM and incubated for 30 min at room temperature (RT. Fig. 1 A, 2).

Medium was then removed from T-150 flasks bearing 80–90% confluent Phoenix Eco cells and the transfection mixture was applied and incubated for 1 min, followed by addition of 31 ml fresh medium (Fig. 1 A, 2). The viral supernatant was discarded 20–24 h after transfection and replaced with 33 ml fresh medium (Fig.

1 A, 5) after transfection, the supernatant was harvested, and viral particles were concentrated by ultracentrifugation for 2 h at 24,000 g at 4°C with a Beckman JS-24 rotor (Beckman Coulter) and resuspended in 0.4 ml murine T cell medium. The retropropecia was then used immediately, or aliquoted, frozen on dry ice, and stored at −80°C. As depicted in Fig.

1 B, murine T cells were isolated from single-cell suspensions of dissociated spleens from CD45.1+ congenic C57BL/6 mice bred in-house at the animal facility of the University of Lausanne (UNIL. Epalinges, Switzerland) using the EasySep Mouse T Cell Isolation Kit (StemCell Technologies. Fig.

1 B, 1.1). T cells were plated at 106/ml in 24- or 48-well plates in T cell medium (described above) and stimulated with αCD3/CD28 Ab-coated beads (Invitrogen) at a bead to cell ratio of 2:1 and 50 IU/ml hIL-2 (Glaxo. Fig.

1 B, 1.1). Non–treated cell-culture grade 48- or 24-well plates (Corning Falcon) were precoated with 0.25 ml or 0.5 ml, respectively, of recombinant RetroNectin (Takara Bio) at a final concentration of 20 μg/ml, overnight (O/N) at 4°C (Fig. 1 B, 1.2).

1 d after T cell activation, the retronectin-precoated plates were washed with PBS, blocked with 2% BSA in PBS for 30 min at RT (Fig. 1 B, 2.1). Subsequently, plates were washed once, retropropecia was added at the MOI indicated in the figures, and plates were then spun at 2,000 g for 1.5 h at 32°C (Fig.

1 B, 2.2). The supernatants were then aspirated, and 0.5 to 106 of 24 h activated T cells were transferred to each coated well (48- or 24-well plates. Fig.

1 B, 2.3). The plates were centrifuged for 10 min at 300 g and incubated O/N (Fig. 1 B, 2.3).

In some experiments the transduction procedure was performed at 48 h, or at both 24 and 48 h after activation. The cultures were maintained at a cell density of 0.5 to 106 cells/ml and replenished with fresh T cell medium (supplemented with hIL-2 alone or hIL-2 followed by hIL-7/IL-15 on day 2 after transduction) every other day (Fig. 1 B, 3).

At day 7, CAR surface expression was assessed by flow cytometric analysis (as described below), and the rested engineered T cells were adjusted for equal expression before functional in vitro and in vivo assays (Fig. 1 B, 4). Murine C1498 leukemia cells were transduced as described above for primary murine T cells, except that they were not activated and were maintained afterwards in DMEM-GlutaMAX complete medium at a cell density of 3 × 105 viable cells/ml.

For flow cytometric analysis, cells were surface stained using antibodies against CD3ε (145-2C11), CD4 (GK1.5, RM4-5), CD8α (53–6.7), CD25 (PC61), CD44 (IM7), CD45.1 (A20), CD45 (30F/11), CD62L (MEL-14), CD69 (H1-2F3), IL-15-Rα (6B4C88), PD-1 (29F.1A12), Ly-6G (1A8), CD11b (M1/70), CD11c (N418), F4/80 (BM8), CD206 (C068C2), NK-1.1 (PK136), CD19 (6D5), and MHC class II (M5/114.15.2). Abs were purchased from eBioscience and BioLegend or produced in-house from hybridomas by the flow cytometry platform. DC101-CAR expression by retrovirally transduced T cells was detected by incubation with soluble mouse VEGFR-2–hIgG-Fc fusion protein (R&D Systems) followed by staining with labeled goat anti-hIgG Fc (clone HP6017.

Biolegend). Thy1.1-T cells were stained in parallel as a negative control. VEGFR-2 expression by mouse endothelial cell lines was evaluated by cell-surface staining with rat anti-VEGFR-2 Ab (clone Avas12.

BioLegend) and matched isotype control (Rat IgG2a κ isotype. Clone RTK2758. BioLegend).

For detection of phosphorylated STAT5, cells were fixed with BD Cytofix Fixation Buffer at 4°C for 15 min and permeabilized with BD Phosflow Perm Buffer III for 30 min at 4°C. Intracellular phospho-staining was performed for 1 h at RT in the dark with Ab against phospho-STAT5 (Tyr694. D47E7 XP Rabbit mAb 4322.

Cell Signaling). For intracellular staining of mIL-15 (clone AIO.3. EBioscience), Bcl-2 (clone 10C4.

EBioscience), and Ki67 (clone SolA15. EBioscience), T cells were fixed and then permeabilized using the FoxP3 transcription factor staining buffer set (eBioscience) according to the manufacturer’s recommendations. For the detection of mIL-15, the cells were further washed and incubated for 30 min with anti-rat IgG2a.

To discriminate dead cells, 7-AAD (BioLegend) staining was performed. Live/dead fixable Aqua Dead cell staining was used to exclude dead cells in the ex vivo analysis of immune cells derived from the spleens, tumors, and tumor-draining lymph nodes according to the manufacturer’s instructions (Molecular Probes, Life Technologies). Data were acquired with a BD flow cytometer and analyzed using FlowJo software (Tree Star).

Cells extracted from dissociated tumors were lysed using TRIzol reagent (Invitrogen, Thermo Fisher Scientific). Total RNA was isolated using the RNeasy Mini Kit (Qiagen). After treatment with RNase-free DNase I (Qiagen), 400 ng of total RNA was reverse transcribed using PrimeScript First Strand cDNA Synthesis Kit (Takara Bio), as indicated by the manufacturer.

Quantitative real-time PCR was performed according to the commercial protocol using SYBR Green Fast PCR Master Mix (Thermo Fisher Scientific) and the 7500 Fast Real-Time PCR System (Applied Biosystems). Primers to specifically amplify regions of the DC101 scFv of the CAR cassette, or the mIL-15 transgene, were designed using the GenScript website and are as follows. DC101 forward, 5′-GCA​ACC​CAA​ACT​CCT​CAT​CT-3′.

DC101 reverse, 5′-TAT​CAT​CAG​CCT​CCA​CAG​GA-3′. IL-15 forward, 5′-CCA​GGA​TCT​ACA​GGC​GAC​AA-3′. IL-15 reverse, 5′-ATG​CTC​TGG​ATC​AGG​CTC​TC-3′.

PCR amplification of the housekeeping gene GAPDH was performed as a control, and to allow normalization of samples. The following primers were used for GAPDH. GAPDH forward, 5′-AGG​TCG​GTG​TGA​ACG​GAT​TTG-3′.

GAPDH reverse, 5′-TGT​AGA​CCA​TGT​AGT​TGA​GGT​CA-3′. Each sample was run in triplicate, and each experiment included three nontemplate control wells. The relative mRNA levels (fold change) of each transgene among the different samples were quantified using the comparative 2−ΔΔCt method.

A continuum propecia results of socioeconomic status ranging from the least to the most privileged persons is evidenced in population studies, with profound implications for health and care.1 Individuals in the most disadvantaged social group suffer from extreme poverty and face several specific challenges to their health and healthcare.2 They frequently cannot meet their most basic needs (including their physiological needs, most acutely exemplified by homelessness) and are at a higher risk of health problems and accelerated ageing due to unhealthy habits (eg, unhealthy diet and drug consumption), harmful environmental and biological factors and social isolation.1–4 As a result, the most socially disadvantaged persons have higher rates of premature mortality, especially caused by suicide and violence, and higher prevalence of all types of diseases, particularly infectious diseases and mental disorders.2 5 Besides, care for chronic conditions is compromised for this population group, which relies to a substantial degree in emergency care, particularly in health systems that do not guarantee universal health coverage.5Even considering the relative size of the most deprived extreme of the social continuum (eg, about 0.5% of the UK adult population in 2018 was considered homeless),6 the scale of …Anyone who has been tracking the public health literature on the greater risks experienced by minority ethnic groups in the hair loss propecia will have been struck by the almost ubiquitous use of the acronym ‘BAME’.

A 2020 report by Public Health England1 on the impact of hair loss treatment on minority ethnic groups mentioned BAME 217 times without defining the term other than spelling out the acronym.

Such usage is redolent of Ian Hacking’s ‘kinds of person’,2 a social group brought into being by the creation of propecia results labels for them and whose life narratives are dependent on social practices associated with such labelling.While ‘BME’ (black and minority ethnic) entered the lexicon in the early 1980s and was first used in Parliamentary proceedings in 1987,3 BAME made a later debut in this source in 2004 but had exceeded BME in frequency by 2020.4 A search of the GOV.UK portal—the website for the UK Government launched in 2012—reveals that results for the use of BAME substantially outpace BME (428 vs 242), a progressively widening gap that now makes it the government’s collective term of choice for minority ethnic groups. Astonishingly, all five petitions submitted in June 2020 to the UK Government and Parliament5 requesting the banning or review of BAME were rejected on the grounds that ‘the Government’s guidance on writing about ethnicity already states that it does not use BAME or BME for a number of reasons’. The disingenuousness propecia results and obvious falsity of the statement derives from the fact that this guidance relates only to the work of the Race Disparity Audit, a small unit in the Cabinet Office, and not to Government as a whole.

The growing usage of these acronyms has also been apparent in the work of the media and the third and private sectors. Indeed, BAME was added to the propecia results Oxford English Dictionary’s ‘new words list’ in 2014, confirming its arrival in the authoritative lexicon of contemporary English and further sustaining its use.The use of BAME is problematic for a number of reasons. A survey by the Race Disparity Audit, the best available evidence, found that among nearly 300 people propecia results across the UK, <1% either recognised the acronym or knew what it stood for,6 against a required government standard of 80% of the UK population.

The term is generally used to refer to all minority ethnic groups except those that are white, thus excluding such groups as Gypsies, Roma and Travellers, some of the most disadvantaged and marginalised in Britain. It is illogically constructed, the use of ‘minority ethnic’ following ‘black’ and ‘Asian’ suggesting that propecia results these pan-ethnicities are not minority ethnic groups. Moreover, the acronym implies that the individuals captured by it are a homogeneous group and it singles out and highlights specific pan-ethnicities (‘black’ and ‘Asian’), raising issues of exclusion and divisiveness.

Latest Prevention propecia generic canada &. Wellness News FRIDAY, propecia generic canada Aug. 28, 2020 (HealthDay News) -- A warning about alcohol-based hand sanitizers in packaging that looks like food or drink has been issued by the U.S. Food and Drug Administration."The agency has propecia generic canada discovered that some hand sanitizers are being packaged in beer cans, children's food pouches, water bottles, juice bottles and vodka bottles," according to an FDA a news release.

"Additionally, the FDA has found hand sanitizers that contain food flavors, such as chocolate or raspberry."Reports received by the FDA include a person who bought what they believed was drinking water but was actually hand sanitizer, and a hand sanitizer using children's cartoons in marketing and sold in a pouch that resembled a snack, CNN reported."I am increasingly concerned about hand sanitizer being packaged to appear to be consumable products, such as baby food or beverages. These products propecia generic canada could confuse consumers into accidentally ingesting a potentially deadly product. It's dangerous to add scents with food flavors to hand sanitizers which children could think smells like food, eat and get alcohol poisoning," FDA Commissioner Dr. Stephen Hahn said in the propecia generic canada release.Copyright © 2019 HealthDay.

QUESTION According to the USDA, there is no difference between a “portion” and a “serving.” See AnswerLatest Cancer News By Steven ReinbergHealthDay ReporterTHURSDAY, Aug. 27, 2020 (HealthDay News)Cancer patients who need radiation therapy shouldn't let fear of hair loss treatment delay their treatment, one hospital study suggests.Over six days in May, during the height of the propecia propecia generic canada in New Jersey, surfaces in the radiation oncology department at Robert Wood Johnson University Hospital in New Brunswick, N.J., were tested for hair loss treatment before cleaning.Of 128 samples taken in patient and staff areas and from equipment, including objects used by a patient with hair loss treatment, not one was positive for hair loss, the propecia that causes hair loss treatment, the study found.Patients can be reassured that surface contamination is minimal and necessary cancer treatment can go forward safely, said lead researcher Dr. Bruce Haffty, chairman of radiation oncology at Rutgers Cancer Institute in New Brunswick."Cancer care should and must continue in a hair loss treatment propecia, and it can be delivered safely and effectively with minimal risk of acquiring a hair loss treatment from the radiation oncology environment, provided routine measures like mask-wearing, hand-washing, distancing and screening are in place and adhered to," Haffty said.The study does have some limitations.

Because of the nature propecia generic canada of environmental sampling, 100% of a surface could not be swabbed for analysis. And no air samples were taken. But Haffty said that because no propecia was found on surfaces, it's doubtful that any propecia was present in the propecia generic canada air."An important thing is that we did this testing before cleaning crews came in at the end of the day when there had been all kinds of traffic with patients and staff moving back and forth," he said.Patients and staff routinely wore masks, maintained social distance and washed their hands often, which is probably why no propecia was found, Haffty said.Patients also were screened on arrival with temperature checks and questioned about propecia symptoms, he added.Dr. Anthony D'Amico propecia generic canada is chief of radiation oncology at Brigham and Women's Hospital in Boston.

He said, "This study corroborates what we have found."Overall, his hospital's rate is 2%, while that in the community next to the hospital is 9%, D'Amico said. But where there are propecia generic canada people with lots of underlying conditions and less access to health care, the rate is 33%, he said."Hospitals seem to be safer right now than public settings -- protocols that people are using are working," D'Amico said.The takeaway. Patients need not put off treatment out of concern that they could be infected in the hospital."We have told patients not to delay radiation because of hair loss treatment, because cancer can be more life-threatening than hair loss treatment," he said.D'Amico's hospital treats patients diagnosed with hair loss treatment who need radiation before other patients arrive in the morning. The department is cleaned after they leave and at the end of the day after all other patients have gone, he propecia generic canada said.Patients with hair loss treatment symptoms must test negative before undergoing screening tests like mammography and colonoscopy, D'Amico added.In the waiting room, patients and staff wear masks and maintain distancing.

Patients' temperatures are taken and they are asked about any symptoms, he said."Patients should feel safe that the person sitting next to them in a waiting room has been properly screened," D'Amico said.The findings were published online Aug. 27 in JAMA Oncology.Copyright © 2020 HealthDay propecia generic canada.

27, 2020 (HealthDay News)Heart attack survivors are more likely to lose weight if their spouses join them in shedding excess pounds, new research shows."Lifestyle improvement after a heart attack is a crucial part of preventing repeat events," said study author Lotte propecia generic canada Verweij, a registered nurse and Ph.D. Student at propecia generic canada Amsterdam University of Applied Sciences, in the Netherlands. "Our study shows that when spouses join the effort to change habits, patients have a better chance of becoming healthier -- particularly when it comes to losing weight."The study included 411 heart attack survivors who, along with receiving usual care, were referred to up to three lifestyle change programs for weight loss, increased physical activity and quitting smoking.The patients' partners could attend the programs for free and were encouraged by nurses to take part.

Her mother, Alvis Whitlow, hadn't been calling as often as usual, which could easily be five times a day. And when propecia generic canada they did speak, Whitlow sounded confused and weak.In late March, a call from Edwards' aunt added to her suspicions. The aunt reported that Whitlow had gastrointestinal problems and couldn't walk to the bathroom without assistance. That's when Edwards knew she needed to act.Edwards took the first propecia generic canada flight she could find, with her husband staying home to take care of their three children and six foster children.On the way to Texas, Edwards thought about the last time she sensed something was seriously wrong with her mom.

It was in 2003, when she too lived in San Antonio.Someone from the beauty shop where Whitlow was getting her hair done called to say her mother had propecia generic canada thrown up and felt weak. This stood out because for much of that week, her mom complained of having a headache, which was unusual."Something's not right," Edwards told the woman at the beauty shop.

He said she'd also need propecia generic canada to be transferred to a hospital set up for hair loss treatment patients."I need you to prepare," the doctor told Edwards. "The patients we've seen with her age and history and how she presented, she only has a 20% chance of living."Edwards thought.

"Here it propecia generic canada was again. A 20% chance."Whitlow spent more than two weeks on a ventilator. Doctors tried to remove her from the ventilator twice, but each time she needed the mechanical help again propecia generic canada within eight hours."You have to make a serious decision," doctors told Edwards.The options.

27, 2020 (HealthDay News)Cancer patients who need radiation therapy shouldn't let fear of hair loss treatment delay their treatment, one hospital study suggests.Over six days in May, during the height of the propecia in New Jersey, surfaces in the radiation oncology department at Robert Wood Johnson University Hospital in New Brunswick, N.J., were tested for hair loss treatment before cleaning.Of 128 samples where can i buy propecia over the counter taken in patient and staff areas and from equipment, including objects used by a patient with hair loss treatment, not one was positive for hair loss, the propecia that causes hair loss treatment, the study found.Patients can be reassured that surface contamination is minimal and necessary cancer treatment can go forward safely, said lead researcher Dr. Bruce Haffty, chairman of radiation oncology at Rutgers Cancer Institute in New Brunswick."Cancer care should and must continue in a hair loss treatment propecia, and it can be delivered safely and effectively with minimal risk of acquiring a hair loss treatment from the radiation oncology environment, provided routine measures like mask-wearing, hand-washing, distancing and screening are in place and adhered to," Haffty said.The study does have some limitations. Because of the nature of environmental sampling, 100% of a surface could where can i buy propecia over the counter not be swabbed for analysis. And no air samples were taken. But Haffty said that because no propecia was found on surfaces, it's doubtful that any propecia was present in the air."An important thing is that we did this testing before cleaning crews came in at the end of the day when there had been all kinds of traffic with patients and staff moving back and forth," he said.Patients and staff routinely wore masks, maintained where can i buy propecia over the counter social distance and washed their hands often, which is probably why no propecia was found, Haffty said.Patients also were screened on arrival with temperature checks and questioned about propecia symptoms, he added.Dr.

Anthony D'Amico is chief of radiation oncology where can i buy propecia over the counter at Brigham and Women's Hospital in Boston. He said, "This study corroborates what we have found."Overall, his hospital's rate is 2%, while that in the community next to the hospital is 9%, D'Amico said. But where there are people with lots of underlying conditions and less access to health care, the where can i buy propecia over the counter rate is 33%, he said."Hospitals seem to be safer right now than public settings -- protocols that people are using are working," D'Amico said.The takeaway. Patients need not put off treatment out of concern that they could be infected in the hospital."We have told patients not to delay radiation because of hair loss treatment, because cancer can be more life-threatening than hair loss treatment," he said.D'Amico's hospital treats patients diagnosed with hair loss treatment who need radiation before other patients arrive in the morning. The department is cleaned after they leave and at the end of the day after all other patients have gone, he said.Patients with hair loss treatment symptoms must test where can i buy propecia over the counter negative before undergoing screening tests like mammography and colonoscopy, D'Amico added.In the waiting room, patients and staff wear masks and maintain distancing.

Patients' temperatures are taken and they are asked about any symptoms, he said."Patients should feel safe that the person sitting next to them in a waiting room has been properly screened," D'Amico said.The findings were published online Aug. 27 in where can i buy propecia over the counter JAMA Oncology.Copyright © 2020 HealthDay.

Currently, there where can i buy propecia over the counter are 21 PMCHA projects in the country. “Children are struggling with a range of emotional and behavioral challenges arising from the hair loss treatment propecia, especially those in families with lower incomes or who face other obstacles to health care,” said HHS Secretary Xavier Becerra. €œThis program harnesses the power of technology to make mental and behavioral health care more accessible and equitable for our nation’s children, and links pediatric care providers to children and their families where can i buy propecia over the counter who need that specialized care.” Research demonstrates an increased need for pediatric mental and behavioral health care. In the United States, about 22 percent of children ages 3 to 17 are currently affected by some type of mental, emotional, developmental, or behavioral condition.

Only about 20% of children where can i buy propecia over the counter with mental, emotional, or behavioral disorders receive care from a specialized provider. €œNow more than ever, families need mental and behavioral health care for their children, but significant disparities in access to this treatment continue to exist,” said Acting HRSA Administrator Diana Espinosa. €œThe expansion of the Pediatric Mental Health Care Access Program paves the way for more children to receive necessary mental health services, especially those in underserved communities.” Pediatric mental health care teams will include child and adolescent psychiatrists, licensed where can i buy propecia over the counter mental health professionals, and care coordinators. Pediatric primary care providers can include, but are not limited to, pediatricians, family physicians, nurse practitioners, physician assistants, and care coordinators.

Teams will use telehealth to consult with pediatric primary care providers.

The Community Mental Health Services Block Grant (MHBG) Program and Substance Abuse Prevention where can i buy propecia over the counter and Treatment Block Grant Program (SABG) will disperse $1.5 billion each to states and territories (with the latter also awarding money to a tribe).

This follows the March announcement of supplemental funding of nearly $2.5 billion for these programs. SAMHSA, an operating division of where can i buy propecia over the counter the U.S. Department of Health and Human Services, has expedited federal funding to grantees to help communities grappling with mental health and substance use needs during the hair loss treatment propecia. The hair loss treatment propecia and the corresponding economic crisis have been especially devastating for Black, American Indian, Alaska Native where can i buy propecia over the counter and Hispanic communities, who are experiencing a disproportionate number of hair loss treatment s and deaths as well as higher-than-average unemployment rates.

Asian American, Native Hawaiian, and Pacific Islander (AANHPI) populations have experienced increased stigma and hate due to hair loss treatment anti-Asian rhetoric, which is impacting the behavioral health of AANHPI communities. The Centers for Disease Control and Prevention (CDC) preliminary data points to 90,000 overdose deaths for the 12 months ending last September – about 20,000 more than the same period the year before. CDC data also where can i buy propecia over the counter shows that American adults in June 2020 reported elevated levels of adverse mental health conditions, substance use, and suicidal ideation. The prevalence of symptoms of anxiety was approximately three times those reported in the second quarter of 2019, and prevalence of depression was approximately four times that reported in the second quarter of 2019.

Last week, the where can i buy propecia over the counter Centers for Medicare &. Medicaid Services (CMS) released data highlighting health services received by millions of Medicaid and Children Health Insurance Program beneficiaries during the hair loss treatment Public Health Emergency. Despite an where can i buy propecia over the counter overall rebound for most of these services, mental health utilization remains below pre-propecia levels. With the nation's mental and substance use disorder needs squarely in focus, HHS Secretary Xavier Becerra is establishing a new Behavioral Health Coordinating Council (BHCC).

The Assistant Secretary for Mental Health and Substance where can i buy propecia over the counter Use and the Assistant Secretary for Health will serve as the co-chairs of this coordinating body, which is comprised of senior leadership from across the Department. The BHCC's primary goal is to facilitate collaborative, innovative, transparent, equitable, and action-oriented approaches to addressing the HHS' behavioral health agenda. "Behavioral health where can i buy propecia over the counter is a priority for the Department of Health and Human Services. The hair loss treatment propecia has made clear the need to invest resources in our nation's mental health and address the inequities that still exist around behavioral health care.

That's why we are making this historic investment in mental health and substance use services," said HHS Secretary Xavier Becerra. "In addition, this national problem calls for where can i buy propecia over the counter Department-wide coordination to address the issue. That's why I am convening the Behavioral Health Coordinating Council to work across HHS to facilitate collaboration and strategic planning as we implement our behavioral health agenda." "Across America, we are seeing a startling rise in mental health and substance use disorders during the hair loss treatment propecia," said Assistant Secretary for Health Dr. Rachel Levine where can i buy propecia over the counter.

"We know multiple stressors during the propecia – isolation, sickness, grief, job loss, food instability, and loss of routines – have devastated many Americans and presented the unprecedented behavioral health challenges across the nation. Addressing the hair loss treatment mental and behavioral health impacts on vulnerable and disenfranchised populations are among the top priorities of where can i buy propecia over the counter the Biden-Harris Administration. Establishing a new Behavioral Health Coordinating Council will assure the right prioritization and guidelines are in place to provide pathways to prevention, intervention, treatment and recovery services." "The Biden-Harris Administration's support through the American Rescue Plan funding will increase community-level supports for Americans who have been grappling with devastating emotional and mental challenges during the hair loss treatment propecia," said Acting Assistant Secretary for Mental Health and Substance Use Tom Coderre. "Given the significant where can i buy propecia over the counter impact mental and substance use disorders can have on the lives of individuals, families and communities, the establishment of the BHCC provides a critical tool in addressing these issues in a collaborative and strategic way." The MHBG program enables states and territories to provide comprehensive community mental health services and address needs and gaps in existing treatment services for those with severe mental health conditions.

The SABG program allows states and territories to plan, implement and evaluate activities to prevent, treat and help more people recover from substance use disorder. This funding will also allow recipients to make investments in existing prevention, treatment and recovery infrastructure, promote support for providers and address unique local needs to deliver substance use where can i buy propecia over the counter disorder services.

SummaryThis report describes sleep duration and sleep quality among U.S. Nonpregnant women aged 40–59 by menopausal status. Perimenopausal women were most likely to sleep less than 7 hours, on average, in a 24-hour period compared with premenopausal and postmenopausal women.

In contrast, postmenopausal women were most likely to have poor-quality sleep. A greater percentage of postmenopausal women had frequent trouble falling asleep, staying asleep, and not waking well rested compared with premenopausal women. The percentage of perimenopausal women with poor-quality sleep was between the percentages for the other two groups in all three categories.

Sleep duration changes with advancing age (4), but sleep duration and quality are also influenced by concurrent changes in women’s reproductive hormone levels (5). Because sleep is critical for optimal health and well-being (6), the findings in this report highlight areas for further research and targeted health promotion. DefinitionsMenopausal status.

A three-level categorical variable was created from a series of questions that asked women. 1) “How old were you when your periods or menstrual cycles started?. €.

2) “Do you still have periods or menstrual cycles?. €. 3) “When did you have your last period or menstrual cycle?.

€. And 4) “Have you ever had both ovaries removed, either as part of a hysterectomy or as one or more separate surgeries?. € Women were postmenopausal if they a) had gone without a menstrual cycle for more than 1 year or b) were in surgical menopause after the removal of their ovaries.

Women were perimenopausal if they a) no longer had a menstrual cycle and b) their last menstrual cycle was 1 year ago or less. Premenopausal women still had a menstrual cycle.Not waking feeling well rested. Determined by respondents who answered 3 days or less on the questionnaire item asking, “In the past week, on how many days did you wake up feeling well rested?.

€Short sleep duration. Determined by respondents who answered 6 hours or less on the questionnaire item asking, “On average, how many hours of sleep do you get in a 24-hour period?. €Trouble falling asleep.

Determined by respondents who answered four times or more on the questionnaire item asking, “In the past week, how many times did you have trouble falling asleep?. €Trouble staying asleep. Determined by respondents who answered four times or more on the questionnaire item asking, “In the past week, how many times did you have trouble staying asleep?.

€ Data source and methodsData from the 2015 National Health Interview Survey (NHIS) were used for this analysis. NHIS is a multipurpose health survey conducted continuously throughout the year by the National Center for Health Statistics. Interviews are conducted in person in respondents’ homes, but follow-ups to complete interviews may be conducted over the telephone.

Data for this analysis came from the Sample Adult core and cancer supplement sections of the 2015 NHIS. For more information about NHIS, including the questionnaire, visit the NHIS website.All analyses used weights to produce national estimates. Estimates on sleep duration and quality in this report are nationally representative of the civilian, noninstitutionalized nonpregnant female population aged 40–59 living in households across the United States.

The sample design is described in more detail elsewhere (7). Point estimates and their estimated variances were calculated using SUDAAN software (8) to account for the complex sample design of NHIS. Linear and quadratic trend tests of the estimated proportions across menopausal status were tested in SUDAAN via PROC DESCRIPT using the POLY option.

Differences between percentages were evaluated using two-sided significance tests at the 0.05 level.

Blumberg, Ph.D., Associate Director for ScienceCoronary biomarkers weren't of great help in deciding whether to defer invasive procedures or to optimize percutaneous coronary intervention (PCI), according to several reports."We need to pay more attention to the precise physiology of what we're measuring and what it means," said K. Lance Gould, MD, of McGovern Medical School at UTHealth in Houston.One group found that routine use of computed tomography-derived fractional flow reserve (FFRCT) did not shave healthcare costs in people with stable chest pain, whereas another reported that operators taking extra steps during stenting did not achieve more optimal FFRs after PCI.Finally, an observational study showed that coronary flow reserve (CFR) couldn't trump FFR at current thresholds in deciding which patients may defer revascularization.The three studies were presented during the same late-breaking trial session at this year's TCT Connect, held virtually by the Cardiovascular Research Foundation.FORECASTResource utilization was about the same whether chest pain clinics in the U.K. Adopted routine FFRCT as a frontline test or continued usual care, according to a randomized trial.Total medical costs -- counting the cost of non-invasive cardiac tests, invasive coronary angiography (ICA), revascularization, hospitalization for cardiac events, cardiac medications, and outpatient attendances -- averaged £1,605.50 at 9 months for people randomly assigned to frontline FFRCT testing vs £1,491.46 in controls (or median £600 vs £670, P=0.962).There was no difference between groups in clinical outcomes nor quality-of-life status at that point, according to Nick Curzen, PhD, of the University of Southampton in England.Thus, the results contradict U.K.

Guidelines, which recommend coronary CT angiography and HeartFlow FFRCT together as a cost-saving strategy based on National Institute for Health and Care Excellence projections.FFRCT is FFR derived from coronary CT angiography, thus providing anatomical and physiological information, and is thought to be a safe way to select patients for subsequent invasive testing and treatment of angina."The real crux of FFRCT is can it save money?. We can, but not by doing it so freely," Curzen concluded at a press conference.For the FORECAST study, investigators had 1,400 people presenting to 11 chest pain clinics in the U.K. Randomized to the test group getting routine FFRCT or usual care.

Median age was around 60 years, and just over half of the participants were men.Coronary CT angiography use was 96% in the test group and 66% in the reference group. Total ICA tests were 14% lower in the test group (P=0.02), which also had 22% fewer patients undergoing ICAs (P=0.01).On closer inspection, the test group had coronary CT angiography alone in 64.9% of cases, as most people had no lesions with >40% stenosis. Another 31.5% actually went on to receive FFRCT assessment.

None underwent stress echocardiography, perfusion scanning, stress MRI, exercise ECG, or ICA testing.In contrast, the reference group had patients stop at coronary CT angiography in 61.4% of cases. Dozens received the other non-invasive and invasive tests.Nevertheless, ICAs and revascularizations were not reduced enough by the FFRCT strategy to make it cost-dominant, Curzen said.TARGET-FFROperators following a physiology-guided incremental optimization strategy did not see an improvement in the number of patients coming out of PCI with optimal FFRs, one center reported.After angiographically successful PCI, FFR was ≥0.90 in 32% of patients, 0.81-0.89 in 39%, and ≤0.80 in 29%, according to Damien Collison, MD, of Golden Jubilee National Hospital and University of Glasgow in Scotland.Patients randomized to further intervention to boost FFR wound up with 38.1% achieving FFR ≥0.90, which was statistically no better than the 28.1% of controls (P=0.099). However, the proportion of patients with a final FFR ≤0.80 was lower in the intervention group (18.6% vs 29.8%, P=0.045).Collison noted that it is rare for operators to assess PCI results using FFR."It's shocking to see so few patients who meet the criteria for optimal physiology at the end of the procedure," said the moderator of the press conference, Roxana Mehran, MD, of Mount Sinai School of Medicine in New York City.Chad Rammohan, MD, of Mountain View Center in California, agreed.

It's "a little sobering" to realize that 30% of patients at a good center are still ischemic at the end of PCI, with an FFR below 0.80. The study moves the field toward optimization and using imaging to make PCI results more durable, he said.The small TARGET-FFR trial was conducted at a single center. Included were 260 people who had angiographically successful PCI before randomization to physiology-guided PCI optimization or usual care.Operators following the intervention algorithm performed further post-dilation, intracoronary imaging, additional stenting depending on coronary physiology results, and hyperemic pullback assessment.Further optimization was targeted in 46% of the intervention group.

Two-thirds of these patients were deemed appropriate for additional post-dilation and/or stenting.In these 40 patients who actually received PCI optimization, mean FFR increased from 0.76 to 0.82 (P<0.00) and mean coronary flow reserve was boosted from 3.0 to 4.0 (P=0.02).Mehran cautioned that perfect is the enemy of the good, as performing extra procedures in PCI may run the risk of cardiac perforation.DEFINE-FLOWFFR-positive patients did not have good clinical outcomes if they had PCI deferred due to a negative CFR result, according to an observational study of combined CFR and FFR assessment.A treatment algorithm for 455 people with stable coronary lesions dictated that only those who had abnormally low FFR (0.8 or below) and CFR (below 2) would receive PCI, with all others receiving initial medical therapy, Gould reported.Resulting major adverse cardiovascular events (MACE) rates, counting all-cause death, myocardial infarction, and revascularization, revealed that outcomes were not equal among patients at 2 years:Concordant negative (FFR-/CFR-). 5.8%Discordant (FFR+/CFR-). 10.8%Discordant (FFR-/CFR+).

12.4%Concordant positive (FFR+/CFR+). 14.4%The 10.8% MACE rate of the FFR+/CFR- group was not as good as the 5.8% rate for FFR-/CFR- (P=0.065 for non-inferiority), Gould reported."Trust the FFR" was Rammohan's take-away in discussing the DEFINE-FLOW study at a press conference.Gould suggested the possibility that reduced FFR and CFR together may still incur additive risk, just at lower thresholds than the ones used for this study. Large randomized trials are needed with thresholds that may actually result in a decrease in morbidity and mortality, he said.CFR is the ratio between resting and maximal possible coronary blood flow.

This measure fails to distinguish flow-limiting stenosis from diffuse or microvascular disease, Gould noted.Mechanisms controlling coronary blood flow are complex, with physiology differing between the subepicardium and the subendocardium. For instance, high flow may be good for the former but not the latter, he said.

The percentage of women aged 40–59 who had trouble staying asleep four times or more in the past week varied by menopausal status.More than one in four nonpregnant women aged 40–59 had trouble staying asleep four times or more in the past week (26.7%) (Figure 3). The percentage of women aged 40–59 who had trouble staying asleep four times or more in the past week increased from 23.7% among premenopausal, to 30.8% among perimenopausal, and to 35.9% among postmenopausal women.

Postmenopausal women were significantly more likely than premenopausal women to have trouble staying asleep four times or more in the past week. Figure 3.

The percentage of women aged 40–59 who did not wake up feeling well rested 4 days or more in the past week varied by menopausal status.Nearly one in two nonpregnant women aged 40–59 did not wake up feeling well rested 4 days or more in the past week (48.9%) (Figure 4). The percentage of women in this age group who did not wake up feeling well rested 4 days or more in the past week increased from 47.0% among premenopausal women to 49.9% among perimenopausal and 55.1% among postmenopausal women. Postmenopausal women were significantly more likely than premenopausal women to not wake up feeling well rested 4 days or more in the past week. Figure 4.

SummaryThis report describes sleep duration and sleep quality among U.S. Nonpregnant women aged 40–59 by menopausal status. Perimenopausal women were most likely to sleep less than 7 hours, on average, in a 24-hour period compared with premenopausal and postmenopausal women.

In contrast, postmenopausal women were most likely to have poor-quality sleep. A greater percentage of postmenopausal women had frequent trouble falling asleep, staying asleep, and not waking well rested compared with premenopausal women. The percentage of perimenopausal women with poor-quality sleep was between the percentages for the other two groups in all three categories. Sleep duration changes with advancing age (4), but sleep duration and quality are also influenced by concurrent changes in women’s reproductive hormone levels (5). Because sleep is critical for optimal health and well-being (6), the findings in this report highlight areas for further research and targeted health promotion.

DefinitionsMenopausal status. A three-level categorical variable was created from a series of questions that asked women. 1) “How old were you when your periods or menstrual cycles started?. €. 2) “Do you still have periods or menstrual cycles?.

€. 3) “When did you have your last period or menstrual cycle?. €. And 4) “Have you ever had both ovaries removed, either as part of a hysterectomy or as one or more separate surgeries?. € Women were postmenopausal if they a) had gone without a menstrual cycle for more than 1 year or b) were in surgical menopause after the removal of their ovaries.

Women were perimenopausal if they a) no longer had a menstrual cycle and b) their last menstrual cycle was 1 year ago or less. Premenopausal women still had a menstrual cycle.Not waking feeling well rested. Determined by respondents who answered 3 days or less on the questionnaire item asking, “In the past week, on how many days did you wake up feeling well rested?. €Short sleep duration. Determined by respondents who answered 6 hours or less on the questionnaire item asking, “On average, how many hours of sleep do you get in a 24-hour period?.

€Trouble falling asleep. Determined by respondents who answered four times or more on the questionnaire item asking, “In the past week, how many times did you have trouble falling asleep?. €Trouble staying asleep. Determined by respondents who answered four times or more on the questionnaire item asking, “In the past week, how many times did you have trouble staying asleep?. € Data source and methodsData from the 2015 National Health Interview Survey (NHIS) were used for this analysis.

NHIS is a multipurpose health survey conducted continuously throughout the year by the National Center for Health Statistics. Interviews are conducted in person in respondents’ homes, but follow-ups to complete interviews may be conducted over the telephone. Data for this analysis came from the Sample Adult core and cancer supplement sections of the 2015 NHIS. For more information about NHIS, including the questionnaire, visit the NHIS website.All analyses used weights to produce national estimates. Estimates on sleep duration and quality in this report are nationally representative of the civilian, noninstitutionalized nonpregnant female population aged 40–59 living in households across the United States.

The sample design is described in more detail elsewhere (7). Point estimates and their estimated variances were calculated using SUDAAN software (8) to account for the complex sample design of NHIS. Linear and quadratic trend tests of the estimated proportions across menopausal status were tested in SUDAAN via PROC DESCRIPT using the POLY option. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level.

Blumberg, Ph.D., Associate Director for ScienceCoronary biomarkers weren't of great help in deciding whether to defer invasive procedures or to optimize percutaneous coronary intervention (PCI), according to several reports."We need to pay more attention to the precise physiology of what we're measuring and what it means," said K. Lance Gould, MD, of McGovern Medical School at UTHealth in Houston.One group found that routine use of computed tomography-derived fractional flow reserve (FFRCT) did not shave healthcare costs in people with stable chest pain, whereas another reported that operators taking extra steps during stenting did not achieve more optimal FFRs after PCI.Finally, an observational study showed that coronary flow reserve (CFR) couldn't trump FFR at current thresholds in deciding which patients may defer revascularization.The three studies were presented during the same late-breaking trial session at this year's TCT Connect, held virtually by the Cardiovascular Research Foundation.FORECASTResource utilization was about the same whether chest pain clinics in the U.K. Adopted routine FFRCT as a frontline test or continued usual care, according to a randomized trial.Total medical costs -- counting the cost of non-invasive cardiac tests, invasive coronary angiography (ICA), revascularization, hospitalization for cardiac events, cardiac medications, and outpatient attendances -- averaged £1,605.50 at 9 months for people randomly assigned to frontline FFRCT testing vs £1,491.46 in controls (or median £600 vs £670, P=0.962).There was no difference between groups in clinical outcomes nor quality-of-life status at that point, according to Nick Curzen, PhD, of the University of Southampton in England.Thus, the results contradict U.K. Guidelines, which recommend coronary CT angiography and HeartFlow FFRCT together as a cost-saving strategy based on National Institute for Health and Care Excellence projections.FFRCT is FFR derived from coronary CT angiography, thus providing anatomical and physiological information, and is thought to be a safe way to select patients for subsequent invasive testing and treatment of angina."The real crux of FFRCT is can it save money?. We can, but not by doing it so freely," Curzen concluded at a press conference.For the FORECAST study, investigators had 1,400 people presenting to 11 chest pain clinics in the U.K.

Randomized to the test group getting routine FFRCT or usual care. Median age was around 60 years, and just over half of the participants were men.Coronary CT angiography use was 96% in the test group and 66% in the reference group. Total ICA tests were 14% lower in the test group (P=0.02), which also had 22% fewer patients undergoing ICAs (P=0.01).On closer inspection, the test group had coronary CT angiography alone in 64.9% of cases, as most people had no lesions with >40% stenosis. Another 31.5% actually went on to receive FFRCT assessment. None underwent stress echocardiography, perfusion scanning, stress MRI, exercise ECG, or ICA testing.In contrast, the reference group had patients stop at coronary CT angiography in 61.4% of cases.

Dozens received the other non-invasive and invasive tests.Nevertheless, ICAs and revascularizations were not reduced enough by the FFRCT strategy to make it cost-dominant, Curzen said.TARGET-FFROperators following a physiology-guided incremental optimization strategy did not see an improvement in the number of patients coming out of PCI with optimal FFRs, one center reported.After angiographically successful PCI, FFR was ≥0.90 in 32% of patients, 0.81-0.89 in 39%, and ≤0.80 in 29%, according to Damien Collison, MD, of Golden Jubilee National Hospital and University of Glasgow in Scotland.Patients randomized to further intervention to boost FFR wound up with 38.1% achieving FFR ≥0.90, which was statistically no better than the 28.1% of controls (P=0.099). However, the proportion of patients with a final FFR ≤0.80 was lower in the intervention group (18.6% vs 29.8%, P=0.045).Collison noted that it is rare for operators to assess PCI results using FFR."It's shocking to see so few patients who meet the criteria for optimal physiology at the end of the procedure," said the moderator of the press conference, Roxana Mehran, MD, of Mount Sinai School of Medicine in New York City.Chad Rammohan, MD, of Mountain View Center in California, agreed. It's "a little sobering" to realize that 30% of patients at a good center are still ischemic at the end of PCI, with an FFR below 0.80. The study moves the field toward optimization and using imaging to make PCI results more durable, he said.The small TARGET-FFR trial was conducted at a single center. Included were 260 people who had angiographically successful PCI before randomization to physiology-guided PCI optimization or usual care.Operators following the intervention algorithm performed further post-dilation, intracoronary imaging, additional stenting depending on coronary physiology results, and hyperemic pullback assessment.Further optimization was targeted in 46% of the intervention group.

Two-thirds of these patients were deemed appropriate for additional post-dilation and/or stenting.In these 40 patients who actually received PCI optimization, mean FFR increased from 0.76 to 0.82 (P<0.00) and mean coronary flow reserve was boosted from 3.0 to 4.0 (P=0.02).Mehran cautioned that perfect is the enemy of the good, as performing extra procedures in PCI may run the risk of cardiac perforation.DEFINE-FLOWFFR-positive patients did not have good clinical outcomes if they had PCI deferred due to a negative CFR result, according to an observational study of combined CFR and FFR assessment.A treatment algorithm for 455 people with stable coronary lesions dictated that only those who had abnormally low FFR (0.8 or below) and CFR (below 2) would receive PCI, with all others receiving initial medical therapy, Gould reported.Resulting major adverse cardiovascular events (MACE) rates, counting all-cause death, myocardial infarction, and revascularization, revealed that outcomes were not equal among patients at 2 years:Concordant negative (FFR-/CFR-). 5.8%Discordant (FFR+/CFR-). 10.8%Discordant (FFR-/CFR+). 12.4%Concordant positive (FFR+/CFR+). 14.4%The 10.8% MACE rate of the FFR+/CFR- group was not as good as the 5.8% rate for FFR-/CFR- (P=0.065 for non-inferiority), Gould reported."Trust the FFR" was Rammohan's take-away in discussing the DEFINE-FLOW study at a press conference.Gould suggested the possibility that reduced FFR and CFR together may still incur additive risk, just at lower thresholds than the ones used for this study.

Large randomized trials are needed with thresholds that may actually result in a decrease in morbidity and mortality, he said.CFR is the ratio between resting and maximal possible coronary blood flow. This measure fails to distinguish flow-limiting stenosis from diffuse or microvascular disease, Gould noted.Mechanisms controlling coronary blood flow are complex, with physiology differing between the subepicardium and the subendocardium. For instance, high flow may be good for the former but not the latter, he said.
