We sought to determine vaccine antibody titres and the prevalence of hepatitis B surface antigen (HBsAg) in both HIV-positive and HIV-negative infants born to HIV-positive mothers in Botswana.

This was a retrospective cross-sectional study using 449 archived dried blood spot samples from both HIV-positive and HIV-negative infants collected between 2016 and 2018.

We screened dried blood spot samples for HBsAg and determined hepatitis B surface antibody titres. We determined hepatitis B virus (HBV) genotypes by amplifying 415 base-pairs of the surface region.

HIV-positive infants mounted a significantly lower immune response to the HBV vaccine (P  < 0.001). Furthermore, a lower proportion of HIV-positive infants had protective hepatitis B surface antibody titres (74.5%) than HIV-negative infants (89.2%) (P < 0.001). HIV-positive infants were older and 50.9% of them had completed vaccination (P = 0.018). Of the 449 infant samples tested, three (0.67%) were positive for HBsAg. Of the three HBsAg-positive infants, two had protective titres (>10 mIU/ml). Two of the three HBV-positive infants were infected with genotype D3 and had no drug-resistance or escape mutations.

Vaccine response was lower among HIV-positive infants compared with HIV-negative infants. HBV infections were observed in both HIV-positive and HIV-negative infants in Botswana. Studies to investigate additional preventive strategies to reduce HBV mother-to-child transmission are recommended.

Male hypogonadism is poorly characterized in young-to-middle-aged people with HIV (PWH). We used a reliable free testosterone assay to assess the prevalence and predictive factors for male hypogonadism in PWH on effective combined antiretroviral therapy (cART).

A French cross-sectional study from January 2013 to June 2016.

We included HIV-1-infected men aged between 18 and 50years with HIV loads of 50 RNA copies/ml or less, on effective cART for at least 6 months. Hypogonadism was defined, according to guidelines, as a mean calculated serum free testosterone concentration less than 70pg/ml (Vermeulen equation). Sociodemographic, anthropo-metric, bone-densitometry, hormonal, immunovirological, metabolic, and therapeutic parameters were collected. The IIEF-5, HAM-D, and AMS scales, respectively, assessed erectile function, depression, and quality of life.

Overall, 240 patients were enrolled, 231 were analyzed. Low free testosterone concentrations (<70pg/ml) were recorded in 20 patients (8.7%), and we years old, and having a total body fat percentage greater than 19% could be used as criteria for identifying PWH at risk. Early screening for male hypogonadism might improve care by identifying patients requiring testosterone replacement.
In response to the complexity, challenges, and slow pace of innovation, health care organizations are adopting interdisciplinary team approaches. Systems engineering, which is oriented to creating new, scalable processes that perform with higher reliability and lower costs, holds promise for driving innovation in the face of challenges to team performance. A patient safety learning laboratory (lab) can be an essential aspect of fostering interdisciplinary team innovation across multiple projects and organizations by creating an ecosystem focused on deploying systems engineering methods to accomplish process redesign.

We sought to identify the role and activities of a learning ecosystem that support interdisciplinary team innovation through evaluation of a patient safety learning lab.

Our study included three participating learning lab project teams. We applied a mixed-methods approach using a convergent design that combined data from qualitative interviews of team members conducted as teams neared the cultilevel system challenges in their health care organization and suggests that the work of such teams benefits from the four types of alignment. Alignment on all four dimensions may yield best results.
Auditory brainstem response (ABR) testing is considered to be relatively resistant to effects of volatile anesthetics. The impact of newer anesthetics on interpretability of ABR testing is unknown. This study compared sevoflurane versus propofol anesthesia on qualitative interpretability of ABR click-testing in children.

This prospective double-blind crossover study enrolled children (≤18 years old) receiving general anesthesia for elective ABR testing. All subjects received both sevoflurane and propofol anesthesias in the same ABR testing session. Deidentified ABR data were reviewed by 5 audiologists (blinded to anesthetic and patient) to determine threshold levels for hearing loss. https://www.selleckchem.com/products/shin1-rz-2994.html The primary outcome was qualitative interpretability (false positive) of ABR click-testing.

Each patient was tested at 4 different intensities in each ear generating 624 records under each anesthetic, for a total of 1248 records. A few patients were tested at 5 different intensities in a single ear accounting for the additi-positive ABR tests, produced by certain anesthetic agents, can have significant life-long impact and negative psychosocial and developmental implications. Use of the intravenous anesthetic propofol is superior to sevoflurane for ABR testing in children.Recent evidence indicates consistent association of low socioeconomic status with epigenetic age acceleration, measured from DNA methylation. As work characteristics and job stressors are crucial components of socioeconomic status, we investigated their association with various measures of epigenetic age acceleration. The study population included employed and unemployed men and women (n=604) from the Northern Finland Birth Cohort 1966. We investigated the association of job strain, effort-reward imbalance and work characteristics with five biomarkers of epigenetic aging (Hannum, Horvath, PhenoAge, GrimAge, and DunedinPoAm). Our results indicate few significant associations between work stress indicators and epigenetic age acceleration, limited to a range of ±2 years, and smoking recording the highest effect on GrimAge age acceleration biomarker between current and no smokers (median difference 4.73 years (IQR 1.18, 8.41). PhenoAgeAA was associated with job strain active work (β=-1.301 95%CI -2.391, -0.212), slowing aging of less than 1.5 years, and working as white-collar slowed aging six months (GrimAgeAA β=-0.683, 95%CI -1.264, -0.102) when compared to blue collars. Association was found for working for more than 40 hours per week that increased the aging over 1.5 years, (HorvathAA β =2.058 95%CI 0.517,3.599, HannumAA β=1.567, 95%CI 0.415,2.719). The pattern of associations was different between women and men and some of the estimated effects are inconsistent with current literature. Our results provide the first evidence of association of work conditions with epigenetic aging biomarkers. However, further epidemiological research is needed to fully understand how work-related stress affects epigenetic age acceleration in men and women in different societies.
Uterine leiomyoma is the most common benign tumor of female genitalia, and the incidence is rising gradually. This study explores the mechanism of miR-29 and STAT3 signaling pathways on uterine leiomyoma.

GSE64763 and GSE5244 datasets were downloaded. Enrichment analyses were performed in GSE64763. PPI network was constructed, and the significant module was identified. Uterine leiomyoma cell lines were divided into NC, miR-29 mimic, anti-NC, and miR-29 inhibitor groups. Plate clone formation and Transwell assays detected the proliferation, invasion, and migration of cells. The expression levels of STAT3, proliferation, EMT, invasion-associated proteins were determined by Western blotting.

Differently expressed genes were mainly enriched in positive regulation of cell migration and gene expression, cell proliferation. Through GSEA, JAK-STAT is a significantly correlated enrichment pathway. A Venn diagram was drawn to identify the common miRNA (miR-29-3p). miR-29 inhibitors promoted protein expression of STAT-3, Cyclin D1, and c-Myc compared with the anti-NC control (P < 0.01), and miR-29 inhibitors promoted cell proliferation in uterine leiomyoma cells (P < 0.05). Furthermore, miR-29 inhibitors promoted the protein expression of MMP-2 and MMP-9 (P < 0.01), and EMT promoting proteins N-cadherin, snail, vimentin, and Transwell assay showed that miR-29 inhibitors promoted cell migration in uterine leiomyoma (P < 0.01).

High expression of miR-29 could inhibit cell proliferation, invasion, and metastasis in uterine leiomyoma, which might be related to the inhibition of the STAT3 signaling pathway, and could provide a novel target for the treatment of uterine leiomyoma.

However, the recent emergence of colistin resistance (ColR) worldwide that severely restricts therapeutic options is a serious threat to global public health. In this study we have investigated the molecular determinants in ColR K. pneumoniae isolates collected from clinical specimens. A total of 98 E. coli and 195 K. pneumoniae clinical isolates were collected from two hospitals from August 2018 to December 2019 in Tehran, Iran. Colistin susceptibility and minimum inhibitory concentrations (MIC) were determined according to the Clinical and Laboratory Standards Institute by disk diffusion method, and microdilution method, respectively. For isolates with colistin MIC ≥4 μg mL-1, PCR was performed for the detection of mcr-1 to mcr-4 genes. Moreover, nucleotide sequences of mgrB, phoP, phoQ, pmrA, and pmrB genes were determined by sequencing. Finally, the transcriptional level of pmrK and pmrC genes was evaluated by quantitative reverse transcription PCR (RT-qPCR). None of the E. coli isolates were resistant to colistin while 21 out 195 K. pneumoniae isolates were identified as resistant, 19 of which carried mutation in the mgrB gene. Three different mutations were observed in the pmrB gene in 3 K. pneumoniae isolates. None of the ColR isolates showed alternations in pmrA, phoP, and phoQ genes. Furthermore, none of the plasmid-encoding genes were detected. Transcriptional level of the pmrK gene increased in all ColR isolates meanwhile, pmrC overexpression was detected in 16 out 21 (76.19%) isolates. Eventually, all ColR isolates were susceptible to tigecycline. Our results demonstrated that the alternation of mgrB gene is the main mechanism related to colistin resistance among ColR K. pneumoniae isolates in this study.
