Purpose: The goal of the study is to determine the inter-rater agreement on multiple factors that were utilized to evaluate the quality of pediatric chest X-ray exams from different levels of healthcare provision in an African setting.Methods: The image quality of pediatric chest X-rays from 3 South African medical centers of varying level of healthcare service were retrospectively assessed by 3 raters for 12 quality factors including: (1) absent body parts; (2) under inspiration; (3) patient rotation; (4) scapula in the way; (5) patient kyphosis/lordosis; (6) artefact/foreign body; (7) central vessel visualization; (8) peripheral vessels visualization; (9) poor collimation; and (10) trachea and bronchi visualization; (11) post-cardiac vessel visualization; and (12) absent or wrong image orientation. Analysis was performed using the Brennan--Prediger coefficient of agreement for inter-rater reliability and Cochran's Q statistic and McNemar's test for inter-rater bias. Read More

Aims Of The Study: This study aimed to assess the prevalence of lipohypertrophy (LH) in diabetes mellitus (DM) patients on insulin therapy and identify factors influencing the prevalence rates through a meta-analysis and meta-regression.Methods: Databases of PubMed, Embase, Scopus, and Google Scholar were screened from inception to 20th Aug 2020. Data on prevalence was transformed using the logit transformation for pooling the proportions using the DerSimonian-Laird meta-analysis model. Read More

Misoprostol entered the global market under the name Cytotec in the mid-1980s for the treatment of gastric ulcers. Decades of research have since demonstrated the safety and effectiveness of off-label use of misoprostol as a uterotonic in pregnant women to prevent and treat post-partum hemorrhage, treat incomplete abortion, or terminate first-trimester pregnancy. Global health experts emphasize misoprostol's potential to revolutionize access to reproductive health care in developing countries. Read More

Background: Difficult or failed intubation of obstetric patients may be up to 8 times higher than in general surgical patients. A decline in obstetric intubation opportunities may be a contributing factor, resulting in reduced training opportunities for junior doctors, who therefore do not acquire airway management skills.Objectives: To assess post-anaesthesia rotation interns' preparedness to manage a difficult/failed obstetric airway scenario.

Root-knot nematodes (RKNs) are one of the most important plant-parasitic nematodes of cereal crops in sub-Saharan Africa. This study was designed to evaluate the rotation effects of different cultivars of sainfoin (Esparsette, Perly, Taja and Visnovsky), soybean (DM-5953-RSF) and alfalfa (BAR 7) with maize (P-2432-R), on a population, compared to monoculture maize. The results showed that sainfoin (Perly and Esparsette) and alfalfa had significantly ( ≤ 0. Read More
