Abstract
Background
Sub-Saharan Africa (SSA) has seen an increase in facility-based births over the years. However, the region has the world’s highest newborn mortality rate (42% in 2019). Quality care around the time of birth can avert these deaths. This study examined the newborn care interventions given to women who gave birth in health facilities in 17 countries in SSA.

Methods
A cross-sectional population-based study was conducted. We used data from the most recent Demographic and Health Surveys (DHS) conducted in 17 sub-Saharan African countries. We analysed a weighted sample of 226,706 women aged 15–49 years who gave birth in the five years preceding the surveys. We described the coverage of nine newborn care services, namely weighing at birth, breastfeeding initiation within 1 h after birth, skin-to-skin contact, temperature measurement, cord examination, counselling on newborn danger signs, counselling on breastfeeding, breastfeeding observation, and child health assessment before discharge.

Results
Overall, 72.0% (95% CI: 71.1, 72.8) of births occurred in health facilities, ranging from 40.0% (95% CI: 38.0, 42.1) in Nigeria to 96.3% (95% CI: 95.4, 97.1) in South Africa. Weighing at birth was the most common intervention (91.4%), followed by health checks before discharge (81%). The other interventions, including those given immediately at birth (breastfeeding and skin-to-skin contact), had suboptimal coverage. For instance, 66% of newborns were breastfed within 1 h after birth, and 56% had immediate skin-to-skin contact. Service coverage varied considerably by country and healthcare provider type.

Conclusions
The majority of the examined services, namely early breastfeeding, skin-to-skin contact, cord examination, temperature measurement, counselling on newborn danger signs, breastfeeding observation, and counselling on breastfeeding, were found to have suboptimal coverage. Even though many pregnant women in SSA give birth in healthcare facilities, some newborns do not always get the care they need to be healthy and live. This is a missed chance to improve newborn health and survival around the time of birth.

Abstract
Background
The COVID-19 pandemic had a major impact on the mental health of healthcare workers (HCWs), especially in low and middle-income countries, which had to face additional political, social, and economic challenges. We thus aimed to assess the prevalence of mental health outcomes and the associated factors in HCWs treating COVID-19 patients in one of the most affected regions in Brazil.

Methods
We used the Respondent-Driven Sampling method to assess the risks of COVID-19 infection and symptoms of mental disorders in nurses, nursing technicians, and physicians who worked on the frontline in the metropolitan region of Recife. 865 healthcare workers completed a survey regarding sociodemographic data, work-related risks, and symptoms of mental disorders - SRQ-20 for common mental disorders (CMD); AUDIT-C for problematic alcohol use; GAD-7 for anxiety; PHQ-9 for depression; PCL-5 for post-traumatic stress disorder (PTSD). Gile’s successive sampling estimator was used to produce the weighted estimates by professional category. A Poisson regression model with robust variance was used to analyze factors associated with a positive screening for CMD. We will present the results of a cross-sectional analysis of the mental health outcomes after the first peak of COVID-19 – from August 2020 to February 2021.

Results
The prevalence ratios for a positive screening for CMD were 34.9% (95% CI: 27.8–41.9) in nurses, 28.6% (95% CI: 21.3–36.0) in physicians, and 26.6% (95% CI: 16.8–36.5) in nursing technicians. Nurses presented a higher prevalence of depressive symptoms (23%). Positive screening for problematic alcohol use (10.5 to14.0%), anxiety (10.4 to 13.3%), and PTSD (3.3 to 4.4%) were similar between the professional categories. The main factors associated with CMD in nurses and physicians were related to an intrinsic susceptibility to mental illness, such as previous or family history of psychiatric disorder, and female sex. Among nurse technicians, work-related factors, such as accidents with biological material, presented the strongest association with CMD.

Conclusion
The mental health of HCWs fighting COVID-19 in Recife was severely affected. It is crucial that healthcare services provide adequate working conditions and psychological support, investing in programs to promote and protect HCWs mental health.

AbstractBackgroundThe architecture of retrorectal fasciae is complex, as determined by different anatomical concepts. The aim of this study was to examine the anatomical characteristics of the inferomedial extension of the urogenital fascia (UGF) involving the pelvis to explore its relationship with the adjacent fasciae. Furthermore, we have expounded on the clinical application of UGF.MethodFor our study, we examined 20 adult male pelvic specimens fixed in formalin, including 2 entire pelvic specimens and 18 semipelvic specimens. Our department has performed 466 laparoscopic rectal cancer procedures since January 2020. We reviewed the surgical videos involving UGF preservation and analyzed the anatomy of the UGF.ResultsThe bilateral hypogastric nerves ran between the visceral and parietal layers of the UGF. The visceral fascia migrated ventrally at the fourth sacral vertebra, which formed the rectosacral fascia together with the fascia propria of the rectum; the parietal layer continually extended to the pelvic diaphragm, terminating at the levator ani muscle. At the third to fourth sacral vertebra level, the two layers constituted the lateral ligaments.ConclusionThe double layers of the UGF are vital structures for comprehending the posterior fascia relationship of the rectum. The upper segment between the fascia propria of the rectum and the visceral layer has no evident nerves or blood vessels and is regarded as the " holy plane” for the operation.

Published: April 2023

Abstract
Background
Effective family planning is associated with substantial benefits, including reductions in maternal and neonatal mortality due to the avoidance of unintended pregnancies, and contributions to spacing, timing, and limiting births. However, in Zanzibar, Tanzania, the utilization of modern contraceptive methods is low. This study therefore aimed to identify barriers to using postpartum family planning among women in Zanzibar.

Methods
Five focus group discussions were conducted with 24 women who gave birth in the maternity unit at a reference hospital in Zanzibar during the first quarter of 2022. The discussions took place in Swahili, were performed with the assistance of an interview guide, and were audio recorded, transcribed in Swahili, and translated to English. Data were analysed with qualitative content analysis using an inductive approach.

Results
Barriers to using postpartum family planning in Zanzibar could be summarized in three generic categories. Inadequate knowledge about postpartum family planning is expressed in the subcategories: inadequate knowledge about contraceptive methods and their mode of action, insufficient quality of family planning services, and belief in traditional and natural medicine for family planning. Perceived risks of modern contraceptive methods are described in the subcategories: fear of being harmed, and fear of irregular bleeding. Limited power in one’s own decision about contraceptive use consist of the subcategories: the need to involve the husband, and opposition and lack of interest from the husband.

Conclusions
The participants’ current knowledge of postpartum family planning was insufficient to either overcome the fear of side-effects or to understand which side-effects were real and likely to happen. The woman’s power in her own decision-making around her sexual reproductive rights is of critical importance. Given the barriers identified in this study, the findings call for increased knowledge about family planning methods and their mode of action, and involvement of the husband throughout pregnancy, childbirth, and the postpartum period in postpartum family planning education and counselling, in Zanzibar and in similar settings.

Introduction
To determine the effectiveness of the Star Family Doctors Training Program, a comprehensive Continuing professional development (CPD) program for general practitioners (GPs) in a compact medical consortium.

Patients and Methods
Observational cohort study with a quantitative analyses in primary health care institutions in Sichuan Province. The interventions were as following: (1) The Star Family Doctors Training Program is a full-time, local government allocation program certified by the Health Department of Sichuan Province, emphasizing small group learning and practice, and using standard patients and medical patient simulators; 30 participants were selected by their institutions. (2) The control group underwent a self-financed after-work CPD program using conventional lectures; 50 participants were self-selected. Short-term effectiveness assessed using immediate post-training tests and self-evaluations; long-term (1 year) effectiveness evaluated using self-reported surveys.

Results
The study involved 80 GPs (28.75% men; mean age: 38.2 ± 9.2 years). The average post-training total score was higher in the STAR group than in the control group (72.83 ± 5.73 vs. 68.18 ± 7.64; p = 0.005). Compared to the controls, STAR participants reported seeing more patients (all p < 0.05), and had more patients who signed family-doctor contracts (p = 0.001) as well as increased patient satisfaction (p = 0.03), respectively. STAR-group trainees appraised the program higher and were more willing to recommend it to colleagues (90% vs. 64%, p = 0.011).

Conclusion
The Star Family Doctors Training Program achieved good responses and provides a reference for future CPD programs.

Abstract
Background
Practical skill assessment is an important part of the learning process to confirm competencies in acquired medical knowledge.

Objective
This study aimed to compare the assessments of endotracheal intubation skills using the HybridLab® methodology between students and teacher in terms of interobserver reliability.

Methods
Reliability analysis was performed with observational data (data are reported according to STROBE guidelines). The study was conducted in two countries, the Lithuanian University of Health Science (LUHS) and Pennsylvania State University (PSU) in the US, between 1 January and 30 June 2020. A total of 92 students (60 from LUHS and 32 from PSU) were trained in endotracheal intubation using an algorithm-driven hybrid learning method. At the end of the training session, the participants had to complete the evaluation scenario, which was assessed by one of the students and evaluated remotely by a single teacher. The student assessment of the endotracheal intubation procedure was compared with the teacher’s assessment using correlation and estimation of the intraclass correlation coefficient.

Results
Overall, the medians of the student and teacher assessments were both 100% (0%). Spearman’s correlation coefficient between the student and teacher assessments was 0.879 (p = 0.001). The intraclass correlation coefficient used for interobserver variations between the students and teacher was 0.883 (95% confidence interval from 0.824 to 0.923).

Conclusions
The algorithm-driven hybrid learning method allows students to reliably assess endotracheal intubation skills to a level comparable with that of the teacher’s evaluation. This learning method has the potential to be a cost-effective and efficient way to provide high-quality education while also saving human resources.

AbstractBackgroundLiver plays an important role in maintaining glucose homeostasis. We aimed to examine the associations of liver enzymes and hepatic steatosis index (HSI, a reliable biomarker for non-alcoholic fatty liver disease) in early pregnancy with subsequent GDM risk, as well as the potential mediation effects of lipid metabolites on the association between HSI and GDM.MethodsIn a birth cohort, liver enzymes were measured in early pregnancy (6-15 gestational weeks, mean 10) among 6,860 Chinese women. Multivariable logistic regression was performed to examine the association between liver biomarkers and risk of GDM. Pearson partial correlation and least absolute shrinkage and selection operator (LASSO) regression were conducted to identify lipid metabolites that were significantly associated with HSI in a subset of 948 women. Mediation analyses were performed to estimate the mediating roles of lipid metabolites on the association of HSI with GDM.ResultsLiver enzymes and HSI were associated with higher risks of GDM after adjustment for potential confounders, with ORs ranging from 1.42 to 2.24 for extreme-quartile comparisons (false discovery rate-adjustedP-trend ≤0.005). On the natural log scale, each SD increment of alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, and HSI was associated with a 1.15-fold (95% CI: 1.05, 1.26), 1.10-fold (1.01, 1.20), 1.21-fold (1.10, 1.32), 1.15-fold (1.04, 1.27), and 1.33-fold (1.18, 1.51) increased risk of GDM, respectively. Pearson partial correlation and LASSO regression identified 15 specific lipid metabolites in relation to HSI. Up to 52.6% of the association between HSI and GDM risk was attributed to the indirect effect of the HSI-related lipid score composed of lipid metabolites predominantly from phospholipids (e.g., lysophosphatidylcholine and ceramides) and triacylglycerol.ConclusionsElevated liver enzymes and HSI in early pregnancy, even within a normal range, were associated with higher risks of GDM among Chinese pregnant women. The association of HSI with GDM was largely mediated by altered lipid metabolism.
Three tyrosine kinase inhibitors cause cardiotoxicity by inducing endoplasmic reticulum stress and inflammation in cardiomyocytes

Published: April 2023

Abstract
Background
Tyrosine kinase inhibitors (TKIs) are anti-cancer therapeutics often prescribed for long-term treatment. Many of these treatments cause cardiotoxicity with limited cure. We aim to clarify molecular mechanisms of TKI-induced cardiotoxicity so as to find potential targets for treating the adverse cardiac complications.

Methods
Eight TKIs with different levels of cardiotoxicity reported are selected. Phenotypic and transcriptomic responses of human cardiomyocytes to TKIs at varying doses and times are profiled and analyzed. Stress responses and signaling pathways that modulate cardiotoxicity induced by three TKIs are validated in cardiomyocytes and rat hearts.

Results
Toxicity rank of the eight TKIs determined by measuring their effects on cell viability, contractility, and respiration is largely consistent with that derived from database or literature, indicating that human cardiomyocytes are a good cellular model for studying cardiotoxicity. When transcriptomes are measured for selected TKI treatments with different levels of toxicity in human cardiomyocytes, the data are classified into 7 clusters with mainly single-drug clusters. Drug-specific effects on the transcriptome dominate over dose-, time- or toxicity-dependent effects. Two clusters with three TKIs (afatinib, ponatinib, and sorafenib) have the top enriched pathway as the endoplasmic reticulum stress (ERS). All three TKIs induce ERS in rat primary cardiomyocytes and ponatinib activates the IRE1α-XBP1s axis downstream of ERS in the hearts of rats underwent a 7-day course of drug treatment. To look for potential triggers of ERS, we find that the three TKIs induce transient reactive oxygen species followed by lipid peroxidation. Inhibiting either PERK or IRE1α downstream of ERS blocks TKI-induced cardiac damages, represented by the induction of cardiac fetal and pro-inflammatory genes without causing more cell death.

Conclusions
Our data contain rich information about phenotypic and transcriptional responses of human cardiomyocytes to eight TKIs, uncovering potential molecular mechanisms in modulating cardiotoxicity. ER stress is activated by multiple TKIs and leads to cardiotoxicity through promoting expression of pro-inflammatory factors and cardiac fetal genes. ER stress-induced inflammation is a promising therapeutic target to mitigate ponatinib- and sorafenib-induced cardiotoxicity.

AbstractBackgroundMultiple preclinical studies have reported a beneficial effect of extracellular vesicles (EVs), especially mesenchymal stem cells derived EVs (MSC-EVs), in the treatment of sepsis. However, the therapeutic effect of EVs is still not universally recognized. Therefore, we conducted this meta-analysis by summarizing data from all published studies that met certain criteria to systematically review the association between EVs treatment and mortality in animal models of sepsis.MethodsSystematic retrieval of all studies in PubMed, Cochrane and Web of Science that reported the effects of EVs on sepsis models up to September 2022. The primary outcome was animal mortality. After screening the eligible articles according to inclusion and exclusion criteria, the inverse variance method of fixed effect model was used to calculate the joint odds ratio (OR) and 95% confidence interval (CI). Meta-analysis was performed by RevMan version 5.4.ResultsIn total, 17 studies met the inclusion criteria. Meta-analysis of those studies showed that EVs treatment was associated with reduced mortality in animal models of sepsis (OR 0.17 95% CI: 0.11,0.26, P < 0.001). Further subgroup analysis showed that the mode of sepsis induction, the source, dose, time and method of injection, and the species and gender of mice had no significant effect on the therapeutic effect of EVs.ConclusionThis meta-analysis showed that MSC-EVs treatment may be associated with lower mortality in animal models of sepsis. Subsequent preclinical studies will need to address the standardization of dose, source, and timing of EVs to provide comparable data. In addition, the effectiveness of EVs in treating sepsis must be studied in large animal studies to provide important clues for human clinical trials.
Cutavirus on the skin in an Asian cohort: identification of a novel geographically related genotype
Authors: Hashida Yumiko , Higuchi Tomonori , Daibata Masanori 
Published: April 2023

Abstract
Background
Cutavirus (CuV) is the newest human parvovirus and is currently receiving increasing attention because of its possible association with cutaneous T-cell lymphoma. Despite the pathogenetic potential of CuV, it has been detected in normal skin; however, little is known about the prevalence, infection levels, and genetic variations of this virus in the skin of the general population.

Methods
We investigated the CuV DNA prevalence and viral loads concerning age, sampling location, and gender using 678 skin swabs collected from the normal-appearing skins of 339 Japanese participants aged 2–99 years. Phylogenetic analyses were also conducted based on the near-full-length CuV sequences identified in this study.

Results
Both the CuV DNA prevalence and viral loads were significantly higher in the skin of elderly persons aged ≥60 years compared with those of persons aged < 60 years. CuV DNA tended to persist in the skin of elderly individuals. No significant difference in viral loads was observed between the skin of the upper arm and the skin of the forehead in CuV DNA-positive specimens. Significantly higher viral loads were evident in men vs. women, although no gender-associated differences in viral prevalence were noted. Phylogenetic analyses demonstrated the existence of Japanese-specific viruses that were genetically distinct from viruses prevalent in other areas, especially Europe.

Conclusions
This large study suggests that high levels of CuV DNA are prevalent on the skin of elderly adults. Our findings also indicated the prevalence of geographically related CuV genotypes. A follow-up study of this cohort should provide helpful information on whether CuV may become pathogenic.
