Introduction: Postpartum haemorrhage (PPH) remains the leading cause of maternal mortality and morbidity globally. Innovative PPH management tools have emerged using suction and sponge tamponade but currently lack substantial evidence. Broader understanding and collaborative research prioritisation are needed, especially in low-income and middle-income countries (LMICs), where the burden of PPH-related mortality is highest.

Background: Ultrasound technology has become integral in antenatal care for its diagnostic effectiveness and potential to improve maternal and neonatal outcomes. Despite its proven benefits, challenges persist in its widespread adoption, particularly in low-resource settings like Kenya.

Aim: The aim of this study was to explore the perspectives of healthcare providers regarding the integration of obstetric point-of-care ultrasound into routine maternal services in low-level facilities Kenya.

Background: Preterm birth is the leading cause of neonatal and under-five mortality worldwide. It is a complex syndrome characterized by numerous etiologic pathways shaped by both maternal and fetal factors. To better understand preterm birth trends, the Global Alliance to Prevent Prematurity and Stillbirth published the preterm birth phenotyping framework in 2012 followed by an application of the model to a global dataset in 2015 by Barros, et al.

Background: Maternal psychological stress has been linked to preterm birth. However, the differential contribution of psychological stress versus stress hormones is not clear. Studies focus primarily on perceived stress and cortisol, with few assessing its inter-convertible hormone cortisone.

Coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus has been implicated in the clinical pathology of multiple organs and organ systems. Due to the novelty of the disease, there is a need to review emerging literature to understand the profile of SARS-CoV-2 in the placenta. This review sought to evaluate the literature on the mediators, mechanism of entry, pathogenesis, detection, and pathology of SARS-CoV-2 in the placenta.

Objective: To investigate the interaction of risks for adverse maternal and perinatal outcomes (stillbirth, predischarge neonatal and maternal mortality) among caesarean section (CS) compared with vaginal deliveries (VD).

Design: Prospective cohort study.

Setting: 10 CS-capable facilities in Busoga Region, East-Central Uganda and Migori County, Kenya.

Objectives: Globally, hundreds of women die daily from preventable pregnancy-related causes, with the greatest burden in sub-Saharan Africa. Five key emergencies-bleeding, infections, high blood pressure, delivery complications and unsafe abortions-account for nearly 75% of these obstetric deaths. Skilled clinicians with strategic supplies could prevent most deaths.

Surgical site infection (SSI) rates in low- and middle-income countries (LMICs) range from 8 to 30% of procedures, making them the most frequent healthcare-acquired infection (HAI) with substantial morbidity, mortality, and economic impacts. Presented here is an approach to surgical site infection prevention based on surveillance and focused on five critical areas identified by international experts. These five areas include 1.

Sepsis is the leading cause of maternal death in sub-Saharan Africa (SSA), a region that sees some of the highest rates of maternal death and morbidity in the world. As one of the most commonly performed surgical procedures in SSA and a proved risk factor for surgical site infection (SSI), cesarean section (CS) is an important operation to target because of its massive impact on maternal and neonatal health. There is currently insufficient published data available on the patient and facility-based context around SSI after CS to establish a true and clear understanding of this infectious category.

The purpose of this study was to characterize the stress experienced by pregnant women in Kenya and assess the relationship between perceived stress and stress-related biomarkers of cortisol and cortisone. Kenyan women are exposed to multiple stressors that may result in chronic stress. However, antenatal stress has not been examined and characterized in Kenya; nor has the relationship between pregnant women's self-reported stress and stress biomarkers been established.

Cesarean section (CS) is the most common operative procedure performed in sub-Saharan Africa (SSA), accounting for as much as 80% of the surgical workload. In contrast to CSs performed in high-income countries, CSs performed in SSA are accompanied by high morbidity and mortality rates. This operation is the most important known variable associated with an increased probability of postpartum bacterial infection.

Objective: Barriers to cervical cancer screening in low-resource settings include lack of accessible, high-quality services, high cost, and the need for multiple visits. To address these challenges, we developed a low-cost, intravaginal, optical cervical imaging device, the point-of-care tampon (POCkeT) colposcope and evaluated whether its performance is comparable with a standard-of-care colposcope.

Materials And Methods: There were 2 protocols, which included 44 and 18 patients.

Introduction: In low-income countries, Surgical Site Infection (SSI) is a common form of hospital-acquired infection. Antibiotic prophylaxis is an effective method of preventing these infections, if given immediately before the start of surgery. Although several studies in Africa have compared pre-operative versus post-operative prophylaxis, there are no studies describing the implementation of policies to improve prescribing of surgical antibiotic prophylaxis in African hospitals.

Background: There is a great need for safe surgical services in sub-Saharan Africa, but a major difficulty of performing surgery in this region is the high risk of post-operative surgical site infection (SSI).

Methods: We aimed to systematically review which interventions had been tested in sub-Saharan Africa to reduce the risk of SSI and to synthesize their findings. We searched Medline, Embase and Global Health databases for studies published between 1995 and 2010 without language restrictions and extracted data from full-text articles.
