Methods: The institution-based cross-sectional study was conducted from November 15, 2022, to March 15, 2023, to recruit 214 study participants during the study period (4 months).

Health-Related Quality of Life and Financial Burden in Ethiopian Patients With Chronic Myeloid Leukemia Receiving Tyrosine Kinase Inhibitors: A Cross-Sectional Study.

Purpose: Health-related quality of life (HRQoL) is now an important goal of therapy for patients with chronic myeloid leukemia (CML). However, there is paucity of data for patients living in low-income countries (LICs) and on factors associated with their HRQoL profile. The primary objective was to compare the HRQoL of patients with CML living in an LIC (Ethiopia) with that of patients living in a high-income country (HIC).

Spatial Heterogeneity and association between the survey-based Women's Empowerment Index (SWPER) and unmet need for birth spacing in sub-Saharan Africa.

Background: Unmet need for birth spacing can significantly impact maternal and child health outcomes, leading to unintended or mistimed births, neonatal mortality, pregnancy loss, induced abortions, small-sized births, and malnutrition. Considering the role of women empowerment in women's sexual and reproductive health, we examined the association between the survey-based women's empowerment index (SWPER) and unmet need for spacing in sub-Saharan Africa (SSA).

Methods: We used data from the Demographic and Health Surveys of 21 in SSA conducted between 2015 and 2021.

Associations between maternal preconception and pregnancy adiposity and neuropsychiatric and behavioral outcomes in the offspring: A systematic review and meta-analysis.

Maternal adiposity (overweight or obesity) has been associated with adverse perinatal outcomes, although the potential risks of long-term neuropsychiatric and behavioral outcomes in the offspring remain unclear. Using the PRISMA guidelines, we searched PubMed, EMBASE, Scopus, and Web of Science to identify studies on maternal adiposity and offspring neuropsychiatric outcomes. Inverse variance-weighted random-effects meta-analyses were used to pool effect estimates with 95 % confidence intervals (95 % CIs) from adjusted odds ratios (OR) and hazard ratios (HR).

Maternal exposure to bioclimatic stress and hypertensive disorders of pregnancy in Western Australia: identifying potential critical windows of susceptibility.

The anthropogenic climate change may impact pregnancy outcomes. Rather than ambient temperature, we aimed to use a composite bioclimatic metric (Universal Thermal Climate Index, UTCI) to identify critical susceptible windows for the associations between bioclimatic exposure and hypertensive disorders of pregnancy (HDPs) risk. Daily UTCI exposure from 12 weeks of preconception through pregnancy was linked to 415,091 singleton pregnancies between 1st January 2000 and 31st December 2015 in Western Australia.

Network analysis of driver genes in human cancers.

Cancer is a heterogeneous disease that results from genetic alteration of cell cycle and proliferation controls. Identifying mutations that drive cancer, understanding cancer type specificities, and delineating how driver mutations interact with each other to establish disease is vital for identifying therapeutic vulnerabilities. Such cancer specific patterns and gene co-occurrences can be identified by studying tumor genome sequences, and networks have proven effective in uncovering relationships between sequences.

Probiotic Supplementation in the Neonatal Age Group and the Risk of Hospitalisation in the First Two Years: A Data Linkage Study from Western Australia.

Background: Probiotic supplementation in preterm neonates is standard practice in many centres across the globe. The impact of probiotic supplementation in the neonatal age group on the risk of hospitalisation in infancy has not been reported previously.

Methods: Infants born < 32 + 6 weeks of gestation in Western Australia were eligible for inclusion.

Prognostic Role of Human Leukocyte Antigen Alleles and Cytokine Single-Nucleotide Polymorphisms in Patients with Chronic Myeloid Leukemia Treated with Tyrosine Kinase Inhibitor Drugs.

Tyrosine kinase inhibitor (TKI) drugs have significantly improved chronic myeloid leukemia (CML) outcomes. Neopeptides from CML cells may induce specific immune responses, which are crucial for deep molecular (DMR) and treatment-free remission (TFR). In this study of Ethiopian patients with CML (n = 162), the HLA alleles and single-nucleotide polymorphisms of five cytokines revealed significant associations with clinical outcomes.
