Deciphering community-level knowledge of obstetric fistula and determinants: perspectives elucidated by ordinal logistic regression.

Background: Obstetric fistula is a significant cause of maternal morbidity in resource-limited settings, where women often suffer due to a lack of prompt access to skilled obstetric services. It is imperative to comprehend and identify the factors that shape community knowledge about obstetric fistula to enhance prevention strategies, enable early detection, and provide support and treatment to affected women. However, there is a substantial gap in the available evidence concerning the level of community knowledge regarding obstetric fistula and its influencing factors within the Ethiopian context.

Postwar nutritional status of lactating mothers: evidence from war-torn Tigray, Ethiopia.

Background: Poor maternal nutrition is a significant public health problem, especially in conflict-affected areas. Lactating mothers are particularly vulnerable due to increased nutritional demands. The recent conflict in the Tigray region has resulted in serious crises and disruptions, worsening maternal undernutrition.

Emerging Low Detection Limit of Optically Activated Gas Sensors Based on 2D and Hybrid Nanostructures.

Gas sensing is essential for detecting and measuring gas concentrations across various environments, with applications in environmental monitoring, industrial safety, and healthcare. The integration of two-dimensional (2D) materials, organic materials, and metal oxides has significantly advanced gas sensor technology, enhancing its sensitivity, selectivity, and response times at room temperature. This review examines the progress in optically activated gas sensors, with emphasis on 2D materials, metal oxides, and organic materials, due to limited studies on their use in optically activated gas sensors, in contrast to other traditional gas-sensing technologies.

Water, sanitation and hygiene (WASH) associated diseases remain a global public health issue and linked with Sustainable Development Goal 6. In November 2020, a war broke out in Tigray, Ethiopia, resulting in a negative health consequence. The post war status of WASH and its associated diseases are not documented.

Antibody gene features associated with binding and functional activity in malaria vaccine-derived human mAbs.

The impact of adjuvants on malaria vaccine-induced antibody repertoire is poorly understood. Here, we characterize the impact of two adjuvants, Alhydrogel® and AS01, on antibody clonotype diversity, binding and function, post malaria vaccination. We expressed 132 recombinant anti-Pfs230D1 human monoclonal antibodies (mAbs) from participants immunized with malaria transmission-blocking vaccine Pfs230D1, formulated with either Alhydrogel® or AS01.

Global burden of potentially life-threatening maternal conditions: a systematic review and meta-analysis.

Background: Potentially life-threatening maternal conditions (PLTCs) is an important proxy indicator of maternal mortality and the quality of maternal health services. It is helpful to monitor the rates of severe maternal morbidity to evaluate the quality of maternal care, particularly in low- and lower-middle-income countries. This study aims to systematically identify and synthesize available evidence on PLTCs.

Knowledge, Attitude, and Practice Regarding Supplemental Iron and Folic Acid Amongst Women Delivering in Edaga-Hamus Community Hospital: A Cross-Sectional Study in Asmara, Eritrea.

Purpose: In Eritrea, every pregnant woman is provided with a supplemental iron and folic acid (IFA) tablet starting from the first antenatal visit throughout the end of pregnancy. In Zoba Maekel, two-third of first antenatal visits have been at either the second or third trimesters. This practice could limit pregnant women's timely access to the nutritional supplement and its benefits.

Antibody gene features associated with binding and functional activity in vaccine-derived human mAbs targeting malaria parasites.

Adjuvants have been essential to malaria vaccine development, but their impact on the vaccine-induced antibody repertoire is poorly understood. Here, we used cDNA sequences from antigen-specific single memory B cells to express 132 recombinant human anti-Pfs230 monoclonal antibodies (mAbs). Alhydrogel-induced mAbs demonstrated higher binding to Pfs230D1, although functional activity was similar between adjuvants.

Factors associated with obstetric fistula among reproductive age women in Ethiopia: a community based case control study.

Immunological characterization of a VIR protein family member (VIR-14) in Plasmodium vivax-infected subjects from different epidemiological regions in Africa and South America.

Plasmodium vivax is a major challenge for malaria control due to its wide geographic distribution, high frequency of submicroscopic infections, and ability to induce relapses due to the latent forms present in the liver (hypnozoites). Deepening our knowledge of parasite biology and its molecular components is key to develop new tools for malaria control and elimination. This study aims to investigate and characterize a P.

Incidence of recovery from severe pneumonia and its predictors among children 2-59 months admitted to pediatric ward of Ayder Comprehensive Specialized Hospital, Tigray, Ethiopia: A retrospective Cohort study.

Background: Pneumonia is a major reason for hospital admission among children, particularly in resource-poor areas. A hospital stay (length of stay) alone is found to contribute for 46.8% of a household cost for single episode of severe pneumonia.

Ten simple rules for creating and sustaining antiracist graduate programs.

In 2020, the combination of police killings of unarmed Black people, including George Floyd, Breonna Taylor, and Ahmaud Arbery, and the Coronavirus Disease 2019 (COVID-19) pandemic brought about public outrage over long-standing inequalities in society. The events of 2020 ignited global attention to systemic racism and racial inequalities, including the lack of diversity, equity, and inclusion in the academy and especially in science, technology, engineering, mathematics, and medicine (STEMM) fields. Racial and ethnic diversity in graduate programs in particular warrants special attention as graduate students of color report experiencing alarming rates of racism, discrimination, microaggressions, and other exclusionary behaviors.

Barriers and Enablers of KMC Implementation in Health Facility and Community of Tigray Region, Northern Ethiopia: Formative Research.

Background: Kangaroo mother care (KMC) is an evidence-based approach to reducing morbidity and mortality in low-birth-weight and preterm newborns. Barriers for KMC and its effective practice at a larger scale are highly affected by contextual factors. The purpose of this study is to explore barriers and enablers in the community and health facilities for implementation and continuation of KMC.

Effect of vaginal scarring on the recovery of surgical repair of obstetric fistula in Northern Ethiopia.

Objective: To determine the effect of vaginal scarring on the recovery from surgical repair of obstetric fistula in Northern Ethiopia from 2015 to 2020.

Methods: A hospital-based retrospective cohort study was conducted among 224 women who had obstetric fistula repair surgery in Northern Ethiopia from March 1 to March 31, 2020. Cox proportional hazards regression model was used to determine the adjusted predictors of recovery for each main baseline predictor variable, using 95% confidence interval (CI) and P < 0.

Burn Intensity Drives the Alteration of Phenolic Lignin to (Poly) Aromatic Hydrocarbons as Revealed by Pyrolysis Gas Chromatography-Mass Spectrometry (Py-GC/MS).

High-intensity wildfires alter the chemical composition of organic matter, which is expected to be distinctly different from low-intensity prescribed fires. Herein, we used pyrolysis gas chromatography/mass spectrometry (Py-GC/MS), in conjunction with solid-state C nuclear magnetic resonance (NMR) and Fourier transform infrared (FT-IR) spectroscopy, to assess chemical alterations from three wildfires and a long-term frequent prescribed fire site. Our results showed that black ash formed under moderate intensity burns contained less aromatic (ArH), polyaromatic hydrocarbon (PAH), and nitrogen-containing compounds (Ntg) but more lignin (LgC) and phenol compounds (PhC), compared to white ash formed under high intensity burns.

Dairy Manure Co-composting with Wood Biochar Plays a Critical Role in Meeting Global Methane Goals.

Livestock are the largest source of anthropogenic methane (CH) emissions, and in intensive dairy systems, manure management can contribute half of livestock CH. Recent policies such as California's short-lived climate pollutant reduction law (SB 1383) and the Global Methane Pledge call for cuts to livestock CH by 2030. However, investments in CH reduction strategies are primarily aimed at liquid dairy manure, whereas stockpiled solids remain a large source of CH.

Professionalism, stigma, and willingness to provide patient-centered safe abortion counseling and care: a mixed methods study of Ethiopian midwives.

Background: Midwives are a large proportion of Ethiopia's health care workforce, and their attitudes and practices shape the quality of reproductive health care, including safe abortion care (SAC) services. This study examines how midwives' conceptions of their professional roles and views on women who have abortions relate to their willingness to provide respectful SAC.

Methods: This study uses a cross-sectional, mixed methods design to conduct a regionally representative survey of midwives in Ethiopia's five largest regions (Oromia; Amhara; Southern Nations, Nationalities, and Peoples [SNNP]; Tigray; and Addis Ababa) with a multistage, cluster sampling design (n = 944).

Restoring function: Positive responses of carbon and nitrogen to 20 years of hydrologic restoration in montane meadows.

Montane meadows are highly productive ecosystems that contain high densities of soil carbon (C) and nitrogen (N). However, anthropogenic disturbances that have led to channel incision and disconnected floodplain hydrology have altered the C balance of many meadows, converting them from net C sinks to net sources of C to the atmosphere. Restoration efforts designed to reconnect floodplain hydrology may slow rates of soil C loss from degraded meadows and restore the conditions for C sequestration and N immobilization, yet questions remain about the long-term impact of such efforts.

Long-Term Effects of Obstetric Fistula on the Overall Quality of Life among Survivors Who Had Undergone Obstetric Fistula Repair, Central Gondar Zone, Northwest Ethiopia, 2020: A Community-Based Study.

Introduction: Childbirth is a special time in the lives of women and families at large. It can also be a time of great tragedy. International reports show that, annually, more than 500,000 women die from pregnancy and childbirth complications globally.

Depth dependence of climatic controls on soil microbial community activity and composition.

Subsoil microbiomes play important roles in soil carbon and nutrient cycling, yet our understanding of the controls on subsoil microbial communities is limited. Here, we investigated the direct (mean annual temperature and precipitation) and indirect (soil chemistry) effects of climate on microbiome composition and extracellular enzyme activity throughout the soil profile across two elevation-bioclimatic gradients in central California, USA. We found that microbiome composition changes and activity decreases with depth.

Beyond bulk: Density fractions explain heterogeneity in global soil carbon abundance and persistence.

Understanding the controls on the amount and persistence of soil organic carbon (C) is essential for predicting its sensitivity to global change. The response may depend on whether C is unprotected, isolated within aggregates, or protected from decomposition by mineral associations. Here, we present a global synthesis of the relative influence of environmental factors on soil organic C partitioning among pools, abundance in each pool (mg C g  soil), and persistence (as approximated by radiocarbon abundance) in relatively unprotected particulate and protected mineral-bound pools.
