Human second trimester Amniotic Fluid Stem Cells (hAFSCs) harbour the potential to differentiate into cells of each of the three germ layers and to form Embryoid Body (EB)-like aggregates, without inducing teratoma formation and with no ethical concerns. However, in spite of the number of reports on hAFSCs-EBs and their characterization, a thorough evaluation in light and electron microscopy of morphological and morphometric features of hAFSCs-EBs development in vitro has not been reported yet. eFT-508 cell line Apart from a superficial layer of epithelial-like flat cells, displaying rare microvilli on the free surface, hAFSCs-EBs enclose inner material, abundant in vesicles and secretory granules, showing early characteristics of connective extracellular matrix dispersed among different types of inner cells. The observation of a number of microvesicles mainly represented by microparticles and, to a lower extent, by exosomes indicates the presence of a complex cellular communication system within this structure. According to morphological analysis, after 7 days of in vitro culture hAFSCs-EB appears as a well-organized corpuscle, sufficiently young to be a carrier of stemness and at the same time, when appropriately stimulated, able to differentiate. In fact, 7-day hAFSCs-EB represents itself an initial cellular transformation towards a specialized structure both in recording and in providing different stimuli from the surrounding environment, organizing structures and cells towards a differentiation fate.The aim of this study is to evaluate the relationship between maternal single nucleotide polymorphisms (SNPs) of methylenetetrahydrofolate reductase (MTHFR) gene with plasma homocysteine (HCY) level and offspring congenital heart diseases (CHDs). 338 mothers with offspring CHDs as case group and 306 mothers of normal children as control group were recruited. Their pregnant histories were interviewed by questionnaire and the MTHFR rsl801133 and rsl801131 were genotyped. The case-control analysis was used to find out the relationship between maternal SNPs of MTHFR gene and offspring CHDs. And the plasma HCY concentration of the mothers of CHDs children was detected. This case-case study was intended to find out the relevance between maternal HCY level and SNPs of MTHFR gene. link2 There were significant differences in the gender of children, occupation of mothers, family history with CHDs, history of abortion, history of adverse pregnancy, early pregnancy health, fetus during pregnancy, pesticide exposure and drug exposure in CHDs group and control group (P  less then  0.05). MTHFR rs1801133 was significantly associated with their offspring CHDs in mothers. The polymorphism of maternal MTHFR rs1801133 increased plasma HCY level, especially the homozygous mutation. Besides the environmental factors, our results suggested that the maternal MTHFR rs1801133 polymorphism might be a risk factor of their offspring CHDs, which may be due to the hyperhomocysteinemia by abnormal metabolism of HCY.
During the COVID-19 outbreak, the presence of extensive white matter microhemorrhages was detected by brain MRIs. The goal of this study was to investigate the origin of this atypical hemorrhagic complication.

Between March 17 and May 18, 2020, 80 patients with severe COVID-19 infections were admitted for acute respiratory distress syndrome to intensive care units at the University Hospitals of Strasbourg for whom a brain MRI for neurologic manifestations was performed. 19 patients (24%) with diffuse microhemorrhages were compared to 18 control patients with COVID-19 and normal brain MRI.

The first hypothesis was hypoxemia. The latter seemed very likely since respiratory failure was longer and more pronounced in patients with microhemorrhages (prolonged endotracheal intubation (p = 0.0002), higher FiO
(p = 0.03), increased use of extracorporeal membrane oxygenation (p = 0.04)). A relevant hypothesis, the role of microangiopathy, was also considered, since patients with microhemorrhages presented a higher increase of the D-Dimers (p = 0.01) and a tendency to more frequent thrombotic events (p = 0.12). Another hypothesis tested was the role of kidney failure, which was more severe in the group with diffuse microhemorrhages (higher creatinine level [median of 293µmol/L versus 112µmol/L, p = 0.04] and more dialysis were introduced in this group during ICU stay [12 versus 5 patients, p = 0.04]).

Blood-brain barrier dysfunction secondary to hypoxemia and high concentration of uremic toxins seems to be the main mechanism leading to critical illness-associated cerebral microbleeds, and this complication remains to be frequently described in severe COVID-19 patients.

A linear valve-like structure at the pulmonary artery terminus is identified on CT in some patients with patent ductus arteriosus (PDA) and can potentially be mistaken for endarteritis. The purpose of this study was to evaluate the differences in CT features between adult patients with PDA and a linear structure and those without.

We retrospectively evaluated ECG-gated cardiac CT of 38 patients with PDA dividing them into two groups [patients with linear symmetrical valve-like structure (group1, n = 16), and those without (group 2, n = 22)]. We analyzed CT findings of the PDA including length, minimal and maximal diameter, presence of calcification, and PDA type, comparing the two subgroups. The authors also investigated the prevalence of endarteritis.

There was no difference in CT findings between the two groups in the prevalence of calcification and length, and minimal and maximal diameter of PDA. Notably the linear valve-like structure was only identified in type 1 PDA (cone-shaped PDA) (p = 0.04), while there were variable types of PDA in group 2. There was only one case of endarteritis as a complication of PDA in group 1. In contrast to a linear valve-like structure, asymmetrical nodular thickening was noted in the patient with endarteritis on CT overlying the pre-existing linear valve-like structure at the pulmonary end of PDA.

A linear valve-like structure is frequently identified at the pulmonary end in type 1 PDA. This CT finding should not be mistaken for endarteritis in the absence of other clinical evidence.

Laparoscopic repair is a well-accepted treatment modality for perforated peptic ulcer (PPU). However, intraoperative conversion to laparotomy is still not uncommon. We aimed to identify preoperative factors strongly associated with conversion.

A retrospective review of records of all PPU patients treated between January 2011 and July 2019 was performed. Patients were divided into three groups laparoscopic repair (LR), conversion to laparotomy (CL), and primary laparotomy (PL). Patient demographics, operative findings, and outcomes were compared between the groups. Logistic regression analyses were performed, taking conversion as the outcome.

Of 822 patients, there were 236, 45, and 541 in the LR, CL, and PL groups, respectively. The conversion rate was 16%. Compared with those in the LR group, patients in the CL group were older (p < 0.001), had higher PULP scores (p < 0.001), had higher ASA scores (p < 0.001) and had hypertension (p = 0.003). PULP score was the only independent risk factor for conversion. The area under the curve (AUC) for the PULP score to predict conversion was 75.3%, with a best cut-off value of ≥ 4. The operative time was shorter for PL group patients than for CL group patients with PULP scores ≥ 4. For patients with PULP scores < 4, LR group patients had a shorter length of stay than PL group patients.

The PULP score may have utility in predicting and minimizing conversion for laparoscopic PPU repair. Laparoscopic repair is the procedure of choice for PPU patients with PULP scores < 4, while open surgery is recommended for those with PULP scores ≥ 4.

The goal of urogynecologic surgeons is to pair patients with the most appropriate and effective surgery. Sacrospinous hysteropexy has become an increasingly utilized surgical option for uterovaginal prolapse repair. The primary aim of this video is to highlight the role that sacrospinous hysteropexy can have in prolapse repair and to demonstrate an anterior approach for this procedure.

We performed a literature review to provide general information on the efficacy, risks, and comparative benefits of sacrospinous hysteropexy. Our video demonstrates the key steps in performing a sacrospinous hysteropexy procedure from an anterior approach including method of dissection, suture fixation to the sacrospinous ligament, and cervical suspension.

Sacrospinous hysteropexy has generally been found to be an effective option for uterovaginal prolapse repair in properly selected patients. The demonstrated approach integrates sacrospinous ligament fixation with an anterior colporrhaphy.

Data and experience to date on sacrospinous hysteropexy are largely based on a posterior approach for access to the sacrospinous ligament. This surgical video demonstrates an anterior approach to sacrospinous hysteropexy that is not well characterized in the literature.

We hypothesized that anatomical changes in the pelvic floor muscles (PFM) could be detected using four-dimensional translabial ultrasound (4D TLUS) in patients with cervical (CC) or endometrial cancer (EC) who underwent pelvic radiotherapy (RT) as digital palpation may present sensitivity limitations.

This was a cross-sectional study that included 64 women (26 with CC and 38 with EC). PFM function was assessed by digital palpation, grading muscle strength according to the Modified Oxford Scale and by 4D TLUS. Ultrasonographic variables were levator plate angle, hiatal area, puborectalis muscle thickness, puborectalis strain and levator ani muscle integrity. These variables were also correlated with clinical and sociodemographic data from all these patients. A 5% significance level was adopted.

When assessed by digital palpation, no significant difference was found in PFM strength between women with CC and those with EC (p = 0.747). However, when assessed by 4D TLUS, women with CC presented greater thickening of the left (p = 0.
