The role of lymphadenectomy in adrenocortical carcinoma resection is controversial. Therefore, we conducted a population-based study to assess the association between positive lymph nodes (LN) and survival.

The Surveillance, Epidemiology, and End Results set of cancer registries were utilized. The associations between positive lymph nodes and tumor size, grade and laterality were assessed. learn more Cancer specific survival (CSS) trends and factors affecting survival were analyzed.

A total of 2170 adult patients were identified; 60% underwent resection. Among those resected, LN were examined in 23% and were positive in 25% of patients with LN examined. Patients with positive LN tended to have smaller tumors compared to those with negative LN (12 ± 5 vs 15 ± 11cm, p = 0.02). The rate of positive LN was higher in right ACC, p = 0.03. Median overall CSS was 21months, with significant differences between resection (42months) and no resection (4months), p < 0.01. Median CSS did not change over time when comparing ACC patients who underwent surgery before 2000, 2000-2009, and 2010-2016. On multivariable analysis including resection group, advanced age, grades III and IV, regional and distant stage, in addition to positive LN were associated with worse survival, p < 0.05.

Lymphadenectomy is infrequently performed during ACC resection, and when performed, regional LN involvement tends to be associated with worse survival. Neoplasm size and grade were not associated with LN involvement and therefore, do not inform lymphadenectomy need. Further studies are needed to assess the indications for, and value of lymphadenectomy in ACC.

As the cardiac mechanisms remain elusive, we investigated the long-term effects (up to 2 months) of empagliflozin on excitation-contraction (EC)-coupling in human cardiomyocytes derived from induced pluripotent stem cells (iPSC-CM) in a blinded manner. IPSC from 3 donors, differentiated into pure iPSC-CM (4 differentiations), were treated with a clinically relevant concentration of empagliflozin (0.5 μmol/l) or vehicle control. Treatment, data acquisition, and analysis were conducted externally blinded. Epifluorescence microscopy measurements in iPSC-CM showed that empagliflozin has neutral effects on Ca2+ transient amplitude, diastolic Ca2+ levels, Ca2+ transient kinetics, or sarcoplasmic Ca2+ load after 2 weeks or 8 weeks of treatment. Confocal microscopy determining possible effects on proarrhythmogenic diastolic Ca2+ release events showed that in iPSC-CM, Ca2+ spark frequency and leak was not altered after chroniraction (EC)-coupling. Human cardiomyocytes derived from induced pluripotent stem cells (iPSC-CM) were used to study a human model including a high repetition number of experiments. Empagliflozin has neutral effects on cardiomyocyte Ca2+ transients, sarcoplasmic Ca2+ load, and diastolic sarcoplasmic Ca2+ leak. In patch-clamp experiments, empagliflozin did not change the action potential. Next-generation RNA sequencing, mapped transcriptome profiles, and Western blots of iPSC-CM untreated and treated with empagliflozin showed no differentially expressed EC-coupling candidates.The kidneys are essential organs that filter the blood, removing urinary waste while maintaining fluid and electrolyte homeostasis. Current conventional research models such as static cell cultures and animal models are insufficient to grasp the complex human in vivo situation or lack translational value. To accelerate kidney research, novel research tools are required. Recent developments have allowed the directed differentiation of induced pluripotent stem cells to generate kidney organoids. Kidney organoids resemble the human kidney in vitro and can be applied in regenerative medicine and as developmental, toxicity, and disease models. Although current studies have shown great promise, challenges remain including the immaturity, limited reproducibility, and lack of perfusable vascular and collecting duct systems. This review gives an overview of our current understanding of nephrogenesis that enabled the generation of kidney organoids. Next, the potential applications of kidney organoids are discussed followed by future perspectives. This review proposes that advancement in kidney organoid research will be facilitated through our increasing knowledge on nephrogenesis and combining promising techniques such as organ-on-a-chip models.
Overweight and obesity are associated with many health problems, including cardiovascular disease (CVD). Evidence from previous studies has shown that extracts from olive leaves rich in olive phenolics are able to positively affect CVD risk factors, such as high blood pressure and dyslipidemia. The aim of this study was to investigate the effect of 8-week olive leaf extract (OLE) administration on blood lipid profiles in overweight/obese subjects with mildly elevated cholesterol levels.

In this randomized, double-blind, placebo-controlled study, 77 healthy adult overweight/obese subjects (aged 56 ± 10years and BMI 29.0 ± 2.7kg/m
) with total cholesterol levels of 5.0-8.0mmol/L (5.9 ± 0.7mmol/L) were randomly assigned to receive 500mg of OLE (n = 39) or placebo (n = 38) for 8weeks. In total, 74 subjects completed the entire study protocol. At baseline, after 4weeks, and after 8weeks of supplementation, blood lipid profiles, oxidized low-density lipoprotein (oxLDL), blood pressure, glucose, and insulin levels were assessed. In addition, liver function parameters were measured at baseline and after 8weeks.

OLE supplementation did not significantly affect blood lipid levels after 4weeks or after 8weeks compared to placebo (all p > 0.05). For oxLDL, blood pressure, glucose, and insulin levels and liver function parameters, also no statistically significant differences were found between the two intervention groups (all p > 0.05).

Blood lipid profiles were not significantly affected by 8weeks OLE supplementation in overweight/obese subjects with mildly elevated cholesterol levels.
