STUDY QUESTION: How long is the allowable warm ischemic time of the uterus and what morphological and biochemical changes are caused by uterine ischemia/reperfusion injury in cynomolgus macaques? SUMMARY ANSWER: Warm ischemia in the uterus of cynomolgus macaques is tolerated for up to 4 h and reperfusion after uterine ischemia caused no further morphological and biochemical changes. WHAT IS KNOWN ALREADY: Uterus transplantation is a potential option for women with uterine factor infertility...

STUDY QUESTION: What is the likelihood of identifying genetic or endocrine abnormalities in a group of boys with 46, XY who present to a specialist clinic with a suspected disorder of sex development (DSD)? SUMMARY ANSWER: An endocrine abnormality of the gonadal axis may be present in a quarter of cases and copy number variants (CNVs) or single gene variants may be present in about half of the cases. WHAT IS KNOWN ALREADY: Evaluation of 46, XY DSD requires a combination of endocrine and genetic tests but the prevalence of these abnormalities in a sufficiently large group of boys presenting to one specialist multidisciplinary service is unclear...

STUDY QUESTION: Do women who place high importance on career success have different perceptions of pregnancy planning, delayed reproduction, and the ethical acceptability of ART than women with less emphasis on their career? SUMMARY ANSWER: Career-focused women place more importance on pregnancy planning, have greater confidence in delayed childbearing, and are more ethically accepting of donor gamete ART than women who do not place as much importance on career success...

STUDY QUESTION: What is the prevalence of leiomyosarcomas and atypical leiomyomas after laparoscopic morcellation of fibroids in reproductive age women? SUMMARY ANSWER: No case of leiomyosarcomas but seven atypical leiomyomas were found in 1216 subjects. WHAT IS KNOWN ALREADY: Although uterine sarcoma is a rare entity affecting usually older peri- or post-menopausal women, the Food and Drug Administration discourages use of laparoscopic power morcellation of uterine fibroids...

We previously proposed that one of the unwanted side effects of chemotherapy and radiotherapy is the increase in several peptide- and non-peptide based chemoattractants in damaged tissues, leading to induction of a prometastatic microenvironment for remaining cancer cells. Herein, we turned out our attention to a potential role of bioactive phospholipids (BphsLs), such as sphingosine-1-phosphate (S1P), ceramide-1-phosphate (C1P), lysophosphatidylcholine (LPC), and lysophosphatidic acid (LPA) in lung cancer (LC) metastasis...

Anti-Müllerian hormone (AMH) is critical to the regression of Müllerian ducts during mammalian male differentiation and targets ovarian granulosa cells and testicular Sertoli and Leydig cells of adults. Specific effects of AMH are exerted via its receptor, AMH type II receptor (Amhr2), but the mechanism by which the Amhr2 gene is specifically activated is not fully understood. To see whether a proximal promoter was sufficient to Amhr2 gene activation, we generated transgenic mice that bore the enhanced green fluorescent protein (EGFP) gene driven by a 500-bp mouse Amhr2 gene promoter...

PURPOSE: To evaluate the clinical significance of dark spots in the donor endothelial cell layer as observed with specular microscopy, in patients who underwent Descemet membrane endothelial keratoplasty (DMEK) for Fuchs endothelial dystrophy (FED). METHODS: Specular microscopy images of 83 consecutive eyes up to 7 years after DMEK were retrospectively reviewed in a masked fashion for the presence of dark spots and morphologic changes in the endothelial cell layer and processed for endothelial cell density (ECD) measurements...

OBJECTIVES: End-of-life decisions are not only common in the ICU but also frequently elicit strong feelings among health professionals. Even though we seek to develop more collegial interprofessional approaches to care and health decision-making, there are many barriers to successfully managing complex decisions. The aim of this study is to better understand how emotions influence the end-of-life decision-making process among professionals working in ICU. DESIGN: Qualitative study with clinical interviews...

PURPOSE OF REVIEW: This review evaluates the state of the art in terms of challenges and strategies used to restore fertility with spermatogonial stem cells retrieved from prepubertal boys affected by cancer. Although these boys do not yet produce spermatozoa, the only option to preserve their fertility is cryopreservation of spermatogonial stem cells in the form of testicular cell suspensions or whole tissue pieces. Different techniques have been described to achieve completion of spermatogenesis from human, spermatogonial stem cells but none is yet ready for clinical application...

BACKGROUND: The purpose of this study was to evaluate the feasibility and safety of ambulatory high-dose methotrexate (HDMTX) administration with oral hydration, alkalinization, and leucovorin rescue. HDMTX (12 g/m) was given intravenously over 4 hours after urine alkalinization. Families and patients were instructed to continue ambulatory oral hydration and alkalinization to monitor urine pH and to adjust bicarbonate according to our institution's treatment algorithm. Clinical status and MTX levels were controlled every 24 hours, and oral leucovorin dose was adjusted accordingly...

OBJECTIVES: To address the impact of underlying immune conditions on the course of septic shock with respect to both mortality and the development of acute infectious and noninfectious complications. DESIGN: An 8-year (2008-2015) monocenter retrospective study. SETTING: A medical ICU in a tertiary care center. PATIENTS: Patients diagnosed for septic shock within the first 48 hours of ICU admission were included. Patients were classified in four subgroups with respect to their immune status: nonimmunocompromised and immunocompromised distributed into hematologic or solid malignancies and nonmalignant immunosuppression...

Magnetic mesoporous silica nanoparticles (M-MSNs) are a promising class of nanoparticles for drug delivery. However, a deep understanding of the toxicological mechanisms of action of these nanocarriers is essential, especially in the liver. The potential toxicity on HepaRG cells of pristine, pegylated (PEG), and lipid (DMPC) M-MSNs were compared. Based on MTT assay and real-time cell impedance, none of these NPs presented an extensive toxicity on hepatic cells. However, we observed by transmission electron microscopy (TEM) that the DMPC and pristine M-MSNs were greatly internalized...

Acute glomerulonephritis due to anti-glomerular basement membrane (anti-GBM) antibody disease is rare, estimated to occur in fewer than one case per million population and accounts for less than 20% of rapidly progressive glomerulonephritis. The prevalence among patients evaluated for potential glomerular disease is lower. It accounts for fewer than 3% of all kidney biopsies done with crescentic glomerulonephritis. Cases of anti-GBM disease occurring in a cluster have rarely been reported. All biopsy proven anti-GBM disease cases were collected from January 2015 to March 2015 at our Institute...

METHODS: Outpatient and inpatient electronic medical system of 21 hospitals in Nanjing during 2016 were retrospectively searched, and all the patients diagnosed with RM were selected. The patients with none crayfish-related RM was excluded. The epidemiology characteristics were depicted. The geographic information system (GIS) was used to collect, manage and analyze the spatial data, to visualize it, to analyze the spatial distribution features of the disease, and to explore the cause of disease prediction...
