Bubble continuous positive airway pressure (BCPAP) has been used in neonates with respiratory distress for decades; however, the optimal setting for BCPAP circuits remains unknown. This study compared the gas exchange efficiency and lung protection efficacy between conventional and high-amplitude BCPAP devices. ⋯ High-amplitude BCPAP reduced lung inflammation and alveolar overdistension in rats with VILI after mechanical ventilation was ceased. Thus high-amplitude BCPAP may offer a superior lung protective effect than conventional BCPAP.

Anemia is the major complication resulting from chronic kidney disease (CKD) and also a risk factor for cardiovascular events and a poor quality of life (QoL). Diabetic kidney disease (DKD) is the major cause of CKD. Initially, insulin resistance has been reported to increase erythropoiesis, but it might be a minor issue. ⋯ Recently, the antidiabetic agent, sodium glucose cotransporter-2 inhibitors (SGLT2i), has been reported to exhibit the renal benefits due to the tubulo-glomerular feedback in addition to sugar control. It may also be due to less renal ischemic through higher EPO levels, followed by higher Hb levels. More studies are needed to clarify the link between the renal benefit of SGLT2i and EPO production.

Self-expandable metal stents (SEMS) are a widely accepted biliary endoprosthesis for patients with unresectable malignant biliary obstruction. Here, we identified predictors for the occlusion of SEMS in unresectable pancreatic cancer patients with biliary tract obstruction. ⋯ In total, 120 patients who received PC-SEMS for unresectable pancreatic cancer were identified. The rate of PC-SEMS occlusion was 37%. The median time to occlusion of PC-SEMS was 359 days. The major causes of occlusion included biliary sludge (61%) and tumor ingrowth (30%). Cox multivariate regression analysis revealed that inadequate alkaline phosphatase/gamma-glutamyl transferase decline (defined by a decrease of <50% within 2 wk after PC-SEMS placement) was the only independent predictor of stent occlusion (hazard ratio, 2.86; 95% CI, 1.28-6.25; p = 0.01) CONCLUSION:: Inadequate alkaline phosphatase/gamma-glutamyl transferase decline is a predictor of occlusion of first-time PC-SEMS placement in unresectable pancreatic cancer patients with biliary tract obstruction.

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age. The etiopathogenesis of the disease remains uncertain. Additionally, a full consensus has not been reached regarding PCOS diagnostic criteria. Several attempts have been made to diagnose PCOS with a simple clinical biomarker, but most of them failed. This study aims to investigate the possible association between PCOS and anogenital distance (AGD), which is an important sign of intrauterine androgen exposure. ⋯ AGD was initially used to define sexual differentiation of animals. Subsequent human studies showed that boys have longer AGDs than girls. Recent studies supporting the hypothesis that extreme prenatal androgen exposure contributes to PCOS found that AGD in adult PCOS patients was longer than control PCOS patients. However, a novel biomarker other than AGD needs to be identified to standardize these measurements. This work represents the first study to evaluate the ratio of anterior AGD to posterior AGD in PCOS patients. In this study, AGD anterior and posterior measurements were longer in PCOS patients than in controls. However, the strongest predictor of PCOS is the ratio of anterior to posterior AGD.
