As the prevalence of advanced heart failure continues to rise, treatment strategies for select patients include heart transplantation or durable left ventricular assist device (LVAD) support, both of which improve quality of life and extend survival. Recently, the HeartMate 3 has been incorporated into clinical practice, the United Network for Organ Sharing donor heart allocation system was revised, and the management of LVAD-related complications has evolved. Contemporary LVAD recipients have greater preoperative illness severity, but survival is higher and adverse event rates are lower compared with prior eras. This is driven by advances in device design, patient selection, surgical techniques, and long-term management. beta-catenin mutation However, bleeding, infection, neurologic events, and right ventricular failure continue to limit broader implementation of LVAD support. Ongoing efforts to optimize management of patients implanted with current devices and parallel development of next-generation devices are likely to further improve outcomes for patients with advanced heart failure.
Maternity leave is highly variable in the United States given the lack of a federal workforce mandate.

The purpose of this study was to describe the experiences and impact of childbearing on women cardiologists and their careers, within a legal framework.

A survey was sent to women cardiologists, asking about their experiences while pregnant and on maternity leave. The incidence of complications and career impacts on the cardiologists was assessed.

Of 323 respondents who had been pregnant as a practicing cardiologist, extra service or call before maternity leave was required in 37.2%. Of those who performed extra service or call, 17.5% were placed on bedrest before delivery, compared with 7.4% who did not perform extra service or call (P=0.005). During the year of pregnancy, 41.2% experienced a salary decrease; only 7.4% had their relative value units prorated for time on maternity leave; 23.2% had no paid maternity leave. Self-reported pregnancy complications occurred in 36.5%, those with complications had a 60% greater chance of reporting that pregnancy adversely affected their career, compared with those without complications. Nearly three-fourths (237 respondents) reported experiencing at least one of several troubling practices that are illegal in many circumstances.

Women cardiologists report wide variances in maternity leave in the United States, with many experiencing likely violations of the Family and Medical Leave Act or other statues. Childbearing issues in cardiologists should be addressed to improve the professional and personal lives of women cardiologists and the attractiveness of cardiology to potential trainees.

The proximate cause of donor brain death is not considered a conventional risk factor in modern heart transplantation.

This study aimed to investigate the effect of the cause of donor brain death on recipients.

Using the United Network for Organ Sharing registry, long-term mortality and allograft failure were compared in recipients who underwent heart transplantation in the United States from 2005 through 2018 between allograft recipients from donors with stroke as the cause of brain death (n=3,761) vs nonstroke causes (n=14,677). Inverse probability weighting was used for risk adjustment. Interactions were investigated between the cause of brain death and other conventional donor risk factors for recipient mortality.

There was an interaction between the cause of brain death and donor age (P
=0.008). When allografts were procured from donors aged 40 years or younger, stroke as the cause of brain death was associated with an increased risk of mortality (23% vs 19% at 5 years; HR 1.17; 95%CI 1.02-1.35)han approximately 40 years.
The subcutaneous (S-) implantable cardioverter-defibrillator (ICD) is an alternative to the transvenous (TV-) ICD that is increasingly implanted in younger patients; data on the safety and effectiveness of the S-ICD in older patients are lacking.

The purpose of this study was to compare outcomes among older patients who received an S- or TV-ICD.

The authors compared S-ICD and single-chamber TV-ICD implants in Fee-For-Service Medicare beneficiaries using the National Cardiovascular Data Registry ICD Registry. Outcomes were ascertained from Medicare claims data. Cox regression or competing-risk models (with TV-ICD as reference) with overlap weights were used to compare death and nonfatal outcomes (device reoperation, device removal for infection, device reoperation without infection, and cardiovascular admission), respectively. Recurrent all-cause readmissions were compared using Anderson-Gill models.

A total of 16,063 patients were studied (age 72.6 ± 5.9 years, 28.4% women, ejection fraction 28.3 ± 8.lantation, risk of death, device reoperation, device removal for infection, device reoperation without infection, and cardiovascular and all-cause readmission were similar among S- and TV-ICD recipients.
Laboratory methods that report low-density lipoprotein cholesterol (LDL-C) include both LDL-C and lipoprotein(a) cholesterol [Lp(a)-C] content.

The purpose of this study was to assess the effect of pelacarsen on directly measured Lp(a)-C and LDL-C corrected for its Lp(a)-C content.

The authors evaluated subjects with a history of cardiovascular disease and elevated Lp(a) randomized to 5 groups of cumulative monthly doses of 20-80mg pelacarsen vs placebo. Direct Lp(a)-C was measured on isolated Lp(a) using LPA4-magnetic beads directed to apolipoprotein(a). LDL-C was reported as 1) LDL-C as reported by the clinical laboratory; 2) LDL-C
=laboratory-reported LDL-C- direct Lp(a)-C; and 3) LDL-C
=laboratory LDL-C - [Lp(a) mass× 0.30] estimated by the Dahlén formula.

The baseline median Lp(a)-C values in the groups ranged from 11.9 to 15.6mg/dL. Compared with placebo, pelacarsen resulted in dose-dependent decreases in Lp(a)-C (2% vs -29% to -67%; P = 0.001-<0.0001). Baseline laboratory-reported mean LDL-C ranged from 68.5 to 89.5mg/dL, whereas LDL-C
ranged from 55 to 74 mg/dL. Pelacarsen resulted in mean percent/absolute changes of -2% to -19%/-0.7 to -8.0mg/dL (P=0.95-0.05) in LDL-C
, -7% to -26%/-5.4 to -9.4mg/dL (P = 0.44-<0.0001) in laboratory-reported LDL-C, and 3.1% to 28.3%/0.1 to 9.5mg/dL (P = 0.006-0.50) increases in LDL-C
. Total apoB declined by 3%-16% (P=0.40-<0.0001), but non-Lp(a) apoB was not significantly changed.

Pelacarsen significantly lowers direct Lp(a)-C and has neutral to mild lowering of LDL-C
. In patients with elevated Lp(a), LDL-C
provides a more accurate reflection of changes in LDL-C than either laboratory-reported LDL-C or the Dahlén formula.

In the obese state, macrophages infiltrate to the adipose tissue (AT), resulting in chronic inflammation and insulin resistance in the AT cells. Recently, attention has been paid to the role of AT macrophages in metabolic disorders should be applied to the initial drug screening step, but it was difficult to mimic the inflammatory adipocytes using the traditional 2-dimensional (2D) culture. In this study, we developed the 3-dimensional (3D) culture system to overcome this limitation. After adipogenic differentiation, lipid droplets were highly accumulated in cells, and differentiation of preadipocytes was not declined by macrophage co-culture. However, only co-cultured cells expressed the insulin resistance features. Compare to mono-cultured adipocytes, co-cultured adipocytes showed reduced glucose uptake and GLUT4 did not translocated to cell membrane even though treatment of high concentration of insulin. Using 3D co-culture model, we develop a microwell-scale drug screening protocol to test anti-obesity effect. 3D cultured cells reacted more sensitive to drugs, and PPARγ antagonist GW9662 (10, 20 μM) repressed adipogenic differentiation in a concentration-dependent manner in 3D co-cultured cells.Cystic fibrosis transmembrane conductance regulator (CFTR) plays crucial role in renal cyst expansion via increase in fluid accumulation. Inhibition of CFTR has been proposed to retard cyst development and enlargement in polycystic kidney disease (PKD). Pinostrobin, a bioactive natural flavonoid, possesses several pharmacological effects. The present study investigated pharmacological effects of pinostrobin on CFTR-mediated Cl- secretion and renal cyst expansion in in vitro and in vivo models. Pinostrobin (10 and 50 μM) reduced number of MDCK cell-derived cyst colonies and inhibited cyst expansion via inhibition of cell proliferation and CFTR-mediated Cl- secretion. The inhibitory effect of pinostrobin was not due to the decrease in cell viability and activity of Na+-K+-ATPase. We also investigated the natural analogue pinocembrin as well as the synthetic analogue pinostrobin oxime. Both pinocembrin and pinostrobin oxime did not reduce CFTR-mediated Cl- secretion. In PKD rats, oral administration of pinostrobin (40 mg/kg/day) exhibited a decreasing in cystic area compared to vehicle-treated rats. Pinostrobin treatment inhibited renal expression of CFTR protein in PKD rats. Our findings highlighted the potential therapeutic application of pinostrobin in PKD.We examined whether galantamine (GAL), a cholinesterase inhibitor and allosteric potentiating ligand for α7 nicotinic acetylcholine receptor (nAChR), had an impact on emotional abnormalities in forebrain-specific cholecystokinin receptor-2 overexpressed transgenic mice. Treatment with GAL (1 mg/kg, s.c.) attenuated the decrease of social interaction time, but failed to attenuate anxiety-like behavior in the elevated plus-maze test. The effect of GAL was blocked by an α7 nAChR antagonist, methyllycaconitine (3 mg/kg, i.p.). These results suggest that GAL improved social interaction impairments via α7 nAChR and could be useful to treat sociability-related emotional abnormalities.Vancomycin is a glycopeptide antibiotic that is a primary treatment for methicillin-resistant Staphylococcus aureus infections. To enhance its clinical effectiveness and prevent nephrotoxicity, therapeutic drug monitoring (TDM) of trough concentrations is recommended. Initial vancomycin dosing regimens are determined based on patient characteristics such as age, body weight, and renal function, and dosing strategies to achieve therapeutic concentration windows at initial TDM have been extensively studied. Although numerous dosing nomograms for specific populations have been developed, no comprehensive strategy exists for individually tailoring initial dosing regimens; therefore, decision making regarding initial dosing largely depends on each clinician's experience and expertise. In this study, we applied a machine-learning (ML) approach to integrate clinician knowledge into a predictive model for initial vancomycin dosing. A dataset of vancomycin initial dose plans defined by pharmacists experienced in vancomycin TDM (i.
