Vitronectin (VTN) has been widely used for the maintenance and expansion of human pluripotent stem cells (hPSCs) as feeder-free conditions. However, the effect of VTN on hPSC differentiation remains unclear. Here, we investigated the role of VTN in early haematopoietic development of hPSCs.

A chemically defined monolayer system was applied to study the role of different matrix or basement membrane proteins in haematopoietic development of hPSCs. The role of integrin signalling in VTN-mediated haematopoietic differentiation was investigated by integrin antagonists. learn more Finally, small interfering RNA was used to knock down integrin gene expression in differentiated cells.

We found that the haematopoietic differentiation of hPSCs on VTN was far more efficient than that on Matrigel that is also often used for hPSC culture. VTN promoted the fate determination of endothelial-haematopoietic lineage during mesoderm development to generate haemogenic endothelium (HE). Moreover, we demonstrated that the signals through αvβ3 and αvβ5 integrins were required for VTN-promoted haematopoietic differentiation. Blocking αvβ3 and αvβ5 integrins by the integrin antagonists impaired the development of HE, but not endothelial-to-haematopoietic transition (EHT). Finally, both αvβ3 and αvβ5 were confirmed acting synergistically for early haematopoietic differentiation by knockdown the expression of αv, β3 or β5.

The established VTN-based monolayer system of haematopoietic differentiation of hPSCs presents a valuable platform for further investigating niche signals involved in human haematopoietic development.

Programmed cell death-ligand 1 (PD-L1) immunohistochemistry score has been approved as the predictive biomarker for anti-PD1/PD-L1 therapy in several advanced malignancies. Although its predictive role remained inconclusive in hepatocellular carcinoma, ongoing study of anti-PD1/PD-L1 therapy showed promising results. However, less is known about the PD-L1 immunohistochemistry score and factors correlated with it in hepatocellular carcinoma. We investigated PD-L1 immunohistochemistry scores in a large cohort of hepatocellular carcinoma, as well as its correlation with various clinical and genomic factors.

Immunohistochemistry was performed to detect the expression of PD-L1 protein in 315 hepatocellular carcinoma tissues. All slides were independently reviewed by three senior pathologists. Next-generation YS panel (450 genes) sequencing was performed on 309 patients.

Higher PD-L1 expression as measured by combined positive score (CPS) was associated with increased Edmondson-Steiner grade (grade III vs II, P=0.041) and TP53 mutations (P=0.021). PD-L1 CPS had no correlation with tumor mutational burden (Spearman's correlation coefficient 0.067). PD-L1 CPS was not significantly associated with hepatitis B virus infection.

Our data indicated that patients with higher Edmondson-Steiner grade (grade III) had significantly higher PD-L1 CPS than patients with lower Edmondson-Steiner grade (grade II). Patients with TP53 mutations had significantly higher PD-L1 expression.

To evaluate etonogestrel (ENG)-implant acceptance during the immediate postnatal period among adolescents and young women during the COVID-19 pandemic, and to compare variables according to choice and discuss possible implications of this measure during the pandemic period.

A cross-sectional study was designed. All women aged up to 24years, who delivered between April 25, 2020, and June 24, 2020, at Women's Hospital, University of Campinas, São Paulo, Brazil were considered. The ENG-implant or other contraceptive methods were offered prior to hospital discharge. The participants were split into two groups (1) those who chose the ENG-implant and (2) those that refused the implant. Descriptive, bivariate, and multivariate analyses were performed.

151 women were included, with 76.2% selecting the ENG-implant. The average age was 19.5years; 73.2% of pregnancies were unplanned, 32.5% already had a previous pregnancy, 74% were single, and 75.5% were not in full time education. Further, 70.5% had previously used contraceptives, with 89.1% unsatisfied with their previous method that opted for the ENG-implant (P=0.07).

Offering the ENG-implant to youths during the immediate postnatal period is evidence-based care, and contraceptive provision is an essential health promotion tool, even during a pandemic. Thinking quickly about public policies in times of crisis is important to guarantee sexual and reproductive rights.

Understanding the epidemiology of Clostridium difficile is important for the development and assessment of infection prevention and control practices, as well as surveillance methods and interpretation of diagnostic testing results.

Our objective was to longitudinally evaluate C. difficile shedding in neonatal foals and mares admitted to a referral hospital neonatal intensive care unit.

Foals admitted to a neonatal intensive care unit, along with their dams.

Rectal swabs were collected from mares and foals at admission, and then approximately every 3 days, when possible. Selective culture for C. difficile was performed and isolates were characterized by toxin gene PCR and ribotyping.

Clostridium difficile was isolated from 103/409 (25%) samples; 65/208 (31%) from foals and 38/201 (19%) from mares. Cumulatively, C. difficile was isolated from at least 1 sample from 50/113 (44%) foals and 30/97 (31%) mares. No association was found between hospitalization day and isolation of C. difficile (P = .13). Twenty-three different ribotypes were identified, with ribotype 078 predominating.
