The application of deep learning for automated segmentation (delineation of boundaries) of histologic primitives (structures) from whole slide images can facilitate the establishment of novel protocols for kidney biopsy assessment. Here, we developed and validated deep learning networks for the segmentation of histologic structures on kidney biopsies and nephrectomies. For development, we examined 125 biopsies for Minimal Change Disease collected across 29 NEPTUNE enrolling centers along with 459 whole slide images stained with Hematoxylin & Eosin (125), Periodic Acid Schiff (125), Silver (102), and Trichrome (107) divided into training, validation and testing sets (ratio 613). Histologic structures were manually segmented (30048 total annotations) by five nephropathologists. Twenty deep learning models were trained with optimal digital magnification across the structures and stains. Periodic Acid Schiff-stained whole slide images yielded the best concordance between pathologists and deep learning segmentation across all structures (F-scores 0.93 for glomerular tufts, 0.94 for glomerular tuft plus Bowman's capsule, 0.91 for proximal tubules, 0.93 for distal tubular segments, 0.81 for peritubular capillaries, and 0.85 for arteries and afferent arterioles). Optimal digital magnifications were 5X for glomerular tuft/tuft plus Bowman's capsule, 10X for proximal/distal tubule, arteries and afferent arterioles, and 40X for peritubular capillaries. Silver stained whole slide images yielded the worst deep learning performance. Thus, this largest study to date adapted deep learning for the segmentation of kidney histologic structures across multiple stains and pathology laboratories. All data used for training and testing and a detailed online tutorial will be publicly available.The ability to overcome cellular barriers in the body is crucial for efficient delivery of drugs to the target where intervention is needed. For drugs acting in the brain it is essential to overcome the blood-brain barrier (BBB). Such drugs include antidotes for the treatment of organophosphate poisoning, a current warfare and terroristic threat. Being lipophilic compounds, organophosphates readily penetrate the brain and block the enzyme acetylcholinesterase (AChE). They cause severe symptoms which may have fatal consequences. A major drawback of currently available oxime reactivators is their inability to reactivate AChE in the central nervous system (CNS) as they are unable to cross the blood-brain barrier. An important obstacle preventing many drugs from reaching their therapeutic target in the brain is the efflux transporter P-glycoprotein (P-gp), whose function is to prevent the penetration of potentially harmful substances. The aim of this study was to evaluate the effect of P-gp on the permeation of oximes into the brain. The study of this interaction was carried out on the CACO-2 cell line, stably expressing P-gp. As it turned out, P-gp has no essential influence on the central availability of clinically used oxime reactivators within this study.The existing information supports the use of this material as described in this safety assessment. The material (phenylacetaldehyde) was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity, skin sensitization, and environmental safety. Data show that phenylacetaldehyde is not genotoxic and provide a calculated margin of exposure (MOE) > 100 for the repeated dose and developmental and reproductive toxicity endpoints. Data from phenylacetaldehyde provided a No Expected Sensitization Induction Level (NESIL) of 590 μg/cm2 for the skin sensitization endpoint. The local respiratory toxicity endpoint was completed using the threshold of toxicological concern (TTC) for a Cramer Class I material, and the exposure to phenylacetaldehyde was below the TTC (0.03 mg/kg/day, 0.03 mg/kg/day, and 1.4 mg/day, respectively). The phototoxicity/photoallergenicity endpoint was completed based on data and ultraviolet (UV) spectra; phenylacetaldehyde is not expected to be phototoxic/photoallergenic. The environmental endpoints were evaluated; phenylacetaldehyde was not found to be persistent, bioaccumulative, and toxic (PBT) as per the International Fragrance Association (IFRA) environmental standards and its risk quotients, based on its current volume of use in Europe and North America (i.e., Predicted Environmental Concentration/Predicted No Effect Concentration [PEC/PNEC]) are less then 1.Perfluorobutanesulfonic acid (PFBS), a shorter chain Per- and polyfluoroalkyl substances (PFASs) cognate of perfluorooctanesulfonic acid (PFOS), has been used as replacement for the toxic surfactant PFOS. However, emerging evidences suggest safety concerns for PFBS and its effect on reproductive health is still understudied. Therefore, the current work aimed to investigate the effect of PFBS, in comparison to PFOS, on reproductive health using Caenorhabditis elegans as an in vivo animal model. PFOS (≥10 μM) and PFBS (≥1000 μM) significantly impaired the reproduction capacity of C. elegans, represented as reduced brood size (total egg number) and progeny number (hatched offspring number), without affecting the hatchability. Additionally, the preconception exposure of PFOS and PFBS significantly altered the embryonic nutrient loading and composition, which further led to abnormalities in growth rate, body size and locomotive activity in F1 offspring. Though the effective exposure concentration of PFBS was approximately 100 times higher than PFOS, the internal concentration of PFBS was lower than that of PFOS to produce the similar effects of PFOS. In conclusion, PFOS and PFBS significantly impaired the reproductive capacities in C. elegans and the preconception exposure of these two compounds can lead to offspring physiological dysfunctions.Enalapril is an angiotensin-converting enzyme (ACE) inhibitor that is used for the treatment of (paediatric) hypertension, heart failure and chronic kidney diseases. Because its disposition, efficacy and safety differs across the paediatric continuum, data from adults cannot be automatically extrapolated to children. This review highlights paediatric enalapril pharmacokinetic data and demonstrates that these are inadequate to support with certainty an age-related effect on enalapril/enalaprilat pharmacokinetics. In addition, our review shows that evidence to support effective and safe prescribing of enalapril in children is limited, especially in young children and heart failure patients; studies in these groups are either absent or show conflicting results. We provide explanations for observed differences between age groups and indications, and describe areas for future research.Glucagon-like peptide-1 (GLP-1) is a potent anti-hyperglycemic hormone that is an alternative treatment choice for patients with type 2 diabetes mellitus (T2DM). The glucose-dependent mechanism of GLP-1 is particularly important because it does not stimulate insulin secretion and cause hypoglycemia when plasma glucose concentrations are in the normal fasting range. Although several peptide drugs of GLP-1 analogs are clinically available, research on the small molecules that stimulate GLP-1 secretion is still struggling. In this review, we summarize recent updates in the discovery of small-molecule GLP-1 secretagogs targeting the G-protein-coupled receptor (GPCR) family. We also discuss the challenges and strategies for the study and describe the latest developments.
The long-term effects of 1 or 2 consecutive obstetrical anal sphincter injuries on bowel continence are still inadequately investigated, and published results remain contradictory.

This study aimed to present detailed descriptive measures of the current bowel incontinence 20 years after the first birth in women who had 2 vaginal deliveries with and without sphincter injuries.

Birth register data were used prospectively and linked to information from a questionnaire survey about current symptoms. Women with 2 singleton vaginal births, from 1992 to 1998, and no further births were retrieved and surveyed by the Swedish Medical Birth Register and Statistics Sweden in 2015. A simple random sample of 11,000 women was drawn from a source cohort of 64,687 women. The cumulative effect was studied in all women with a repeat sphincter injury from 1987 to 2000. Postal and web-based questionnaires were used. The study population consisted of 6760 women with no sphincter injury, 357 with 1 sphincter injury, and 324 wly cumulative. After the age of 52 years, the prevalence of fecal incontinence seemed to accelerate.
Women with polycystic ovary syndrome are at a higher risk of cardiometabolic and psychiatric comorbidities and preconception and antepartum complications, but the impact of polycystic ovary syndrome during the postpartum period is unknown.

This study aimed to investigate the risk of postpartum cardiovascular disease complications and perinatal and postpartum depression.

This was a retrospective cohort study conducted using a United States insurance claims database. Women with and without polycystic ovary syndrome aged 18 to 50 years enrolled continuously in a single health plan during the preconception, antepartum, and postpartum periods between 2000 and 2016 were included. The primary outcome was postpartum cardiovascular disease and depression (perinatal and postpartum). Multivariable logistic regression was used to adjust for covariates including age, geographic location, preterm delivery, assisted reproductive technology use, multiple births, prepregnancy depression, prepregnancy diabetes, prepregnaeased risk of both cardiovascular and psychiatric complications during the postpartum period. Polycystic ovary syndrome should be recognized as an at-risk condition; our findings underscore the need for routine screening and early interventions for these major comorbidities.
In a large United States cohort, our study found that women with polycystic ovary syndrome are at increased risk of both cardiovascular and psychiatric complications during the postpartum period. Polycystic ovary syndrome should be recognized as an at-risk condition; our findings underscore the need for routine screening and early interventions for these major comorbidities.Preeclampsia is defined as hypertension arising after 20 weeks of gestational age with proteinuria or other signs of end-organ damage and is an important cause of maternal and perinatal morbidity and mortality, particularly when of early onset. Although a significant amount of research has been dedicated in identifying preventive measures for preeclampsia, the incidence of the condition has been relatively unchanged in the last decades. This could be attributed to the fact that the underlying pathophysiology of preeclampsia is not entirely understood. There is increasing evidence suggesting that suboptimal trophoblastic invasion leads to an imbalance of angiogenic and antiangiogenic proteins, ultimately causing widespread inflammation and endothelial damage, increased platelet aggregation, and thrombotic events with placental infarcts. Aspirin at doses below 300 mg selectively and irreversibly inactivates the cyclooxygenase-1 enzyme, suppressing the production of prostaglandins and thromboxane and inhibiting inflammation and platelet aggregation.
