Bibliometric Analysis Of Congenital Toxoplasmosis: A Ten-Year (2013-2023) Review Of Research Publications, Festus Mulakoli, Horatius Musembi, Ann Kimani

School of Nursing & Midwifery, East Africa

Background:Toxoplasma gondii, an obligate intracellular protozoan, infects more than one-third of the global population and causes toxoplasmosis, which can lead to severe fetal complications in pregnant women. The global prevalence of latent toxoplasmosis in pregnant women is 33.8%, with regional variations and risk factors, including the consumption of undercooked meat, exposure to cat feces, and consumption of contaminated water. Pregnant women lack sufficient awareness of these risk factors, necessitating enhanced education, regular screening, and counseling during antenatal care for early detection and management.

Aim: This study performed a comprehensive bibliometric analysis of research on congenital toxoplasmosis published between 2013 …

Smelling is a human sense, expressing strong sexual dimorphisms. We aim to improve the knowledge of the genetics of human olfactory perception by performing an exploratory genome-wide association meta-analysis of up to 21,495 individuals of European ancestry. By sex-stratified and overall analysis of the identification of twelve odours and an identification score, we discovered ten independent loci, seven of them novel, with trait-wise genome-wide significance (p <  5 × 10−8) involving five odours. Seven of these loci, including four novel ones, are also significant using a stricter study-wide significance threshold (p <  3.85 × 10−9). Loci were predominantly located within clusters of olfactory receptors. Two loci were female-specific while one was sex-differential with respective candidate genes containing androgen response elements. Two-sample Mendelian randomization was applied to search for causal relationships between sex hormones, odour identification and neurodegenerative diseases. A causal negative effect was detected for Alzheimer’s disease on the identification score. These findings deepen our understanding of the genetic basis of olfactory perception and its interaction with sex, prioritizing mechanisms for further molecular research.

Inversions are known contributors to the pathogenesis of genetic diseases. Identifying inversions poses significant challenges, making it one of the most demanding structural variants (SVs) to detect and interpret. Recent advancements in sequencing technologies and the development of publicly available SV datasets have substantially enhanced our capability to explore inversions. However, a cross-comparison in those datasets remains unexplored. In this study, we reported a proband with familial hemophagocytic lymphohistiocytosis type-3 carrying a splicing variant (c.1389+1G>A) in trans with an inversion present in 0.006345% of individuals in gnomAD (v4.0) that disrupts UNC13D. Based on this result, we investigate the features …

Adverse childhood experiences, such as household dysfunction (HD), play a central role in how adolescents establish, experience, and navigate the challenges of relationship formation, maintenance, and dissolution. HD exposures have been independently associated with dating violence (DV) perpetration in both adolescents and adults. However, research examining the association between the concurrent effect of HD on DV perpetration, especially among adolescents remains scarce. Thus, we conducted a scoping review to accumulate and summarize existing research regarding the impact of HD on DV perpetration among adolescents aged 10 to 17 years in the United States. We used three electronic databases, Medline (Ovid), …

Pregnant women infected with SARS-CoV2 are more likely to be hospitalized and require ventilation, compared to non-pregnant women. Although the development of the COVID-19 vaccine was regarded as a scientific breakthrough among many, the pace of development in combination with delayed and unclear recommendations for maternal vaccination led to slower vaccine uptake among this population. We explored the decision-making process for COVID-19 vaccination among pregnant and postpartum women in four countries: Brazil, Ghana, Kenya, and Pakistan through 201 in-depth interviews. A grounded theory approach was used for analysis, and a socio-ecological framework was used to synthesize emerging themes. Four levels …

Introduction

Pregnant women are at increased risk of severe manifestations of COVID-19, resulting in ICU admission, mechanical ventilation, and death compared to non-pregnant women. COVID-19 vaccines were approved for use in pregnant women in early 2022 by the World Health Organization, but permissive policies toward vaccine women differed by country. As education has been associated with vaccine uptake, this study sought to examine the association between socio-economic or educational status and vaccination behaviors, including reasons for vaccination or non-vaccination among pregnant women seeking health care services in Nairobi, Kenya.

Methods

This study administered a survey to pregnant women at the …

Multiple micronutrient supplements (MMS) in pregnancy reduces risk of infant low birthweight (LBW) and improves other maternal and infant outcomes compared with iron and folic acid (IFA) supplements alone. However, the impact of timing of initiation and adherence on the MMS effectiveness in real-world programs remains unclear. To address this, we conducted a 2-stage individual participant data meta-analysis that included 15 randomized trials (61,204 pregnant women) and assessed whether the relative effect of MMS differed by the following: adherence alone; adherence in combination with gestational age at initiation; and the total number of tablets taken. We also evaluated the observational …

Clinico-Epidemiological Characteristics Of Cerebral Venous Sinus Thrombosis In Kenya: A Retrospective Case Series, Taby Siika, Jaskirat Sokhi, Juzar Hooker, Sheila Waa, Anne Mwirigi, Jasmit Shah, Dilraj Sokhi

Internal Medicine, East Africa

Background: Cerebral venous sinus thrombosis (CVST) is a rare cause of stroke that is more common in young, especially female, adults and can be challenging to diagnose due to its frequently non-specific presentation and diverse risk factors. Most cases are idiopathic, and international guidelines do not recommend routine investigations for underlying thrombophilia. Timely diagnosis, with prompt neuroimaging and guideline-based treatment, leads to good outcomes. However, in the literature on CVST from sub-Saharan Africa, the gap is substantial, with the few cases described as being related to systemic and/or brain infections. We describe here the largest cohort of CVST from the …

IMPORTANCE: Recent studies have identified characteristic symptom patterns of long COVID (LC) in adults and children older than 5 years. However, LC remains poorly characterized in early childhood. This knowledge gap limits efforts to identify, care for, and prevent LC in this vulnerable population.

OBJECTIVES: To identify symptoms that had the greatest difference in frequency comparing children with a history of SARS-CoV-2 infection to those without, to identify differences in the types of symptoms by age group (infants/toddlers [0-2 years] vs preschool-aged children [3-5 years]), and to derive an index that can be used in research studies to identify young …

Purpose: To develop a practical framework for creating a diverse set of validated reference plans (varying in complexity) and implement a workflow to introduce beam modeling, calibration, and delivery errors into the reference cohort to test and compare various dosimetry audit methodologies.

Methods: Sixteen IMRT and VMAT reference plans were created, using RayStation software, for four phantom geometries based on established credentialing cases from participating Global Harmonization Group (GHG) members. These reference plans were first validated in a multi-ion-chamber phantom. Nine dosimetric errors (perturbations) were introduced into the plans by modifying beam model and/or delivery parameters (MLC-offset, MLC-transmission, leaf-tip-width, PDD, …

BACKGROUND: Standard-of-care treatment of localized undifferentiated pleomorphic sarcoma (UPS) involves preoperative radiotherapy (RT) and surgery. Combination of RT with immune-checkpoint blockade (ICB) represents a promising new strategy.

METHODS: Our primary objective was to assess survival outcomes and pathologically documented response in patients receiving RT with or without ICB or chemotherapy.

RESULTS: In a retrospective cohort of 68 patients with primary or locally recurrent UPS who received neoadjuvant RT with or without ICB, the ICB group had greater tumor hyalinization than the non-ICB group (89% compared with 30%, P = 0.018). In the non-ICB group, 19/37 patients (51%) achieved hyalinization-based pathologic …
