Objectives: To assess the geographical equity in Ethiopian infants' exclusive breastfeeding at 5 months and dietary diversity at 12 months and whether social factors explained the spatial inequities.
Design: Secondary analysis of a birth cohort study.
Setting: Analysis of data from the Ethiopian Performance Monitoring for Action panel study conducted from July 2020 to August 2021 in five regions (ie, Oromia, Amhara, Afar and Southern Nations, Nationalities and Peoples regions and the Addis Ababa City administration).
Background: We aimed to evaluate the trend of post-term births over time and their association with perinatal mortality based on prospective pregnancy cohorts in a rural area in Bangladesh.
Methods: This cohort study included 72 373 singleton births with gestational ages ≥28 weeks recorded by a health and demographic surveillance system from 1990 to 2019 in Matlab, Bangladesh. We expressed the gestational age as X (weeks) + Y (days)/7 weeks, where X indicated complete weeks, and Y presented the number of completed days out of seven days or a week.
Objective: Negative effects of psychotherapy are a broad term that encompasses events such as non-response, deterioration, and novel symptoms. The aim of the present study was to explore experiences with negative effects among clinicians working within an intensive short-term dynamic psychotherapy (ISTDP) framework.
Method: Eight ISTDP clinicians consented to participate and were interviewed using semi-structured video interviews.
Article Synopsis
- Native mass spectrometry (nMS) helps to study biomacromolecules in their natural states by using gentle electrospray ionization (ESI), preserving key noncovalent interactions.
- The research investigates how negatively charged DNA affects the ESI charge of protein complexes, leading to a lower mass-to-charge ratio and increased variability in protein-DNA interactions.
- The study reveals that the structural characteristics of protein-DNA complexes can cause them to have lower charge states than would typically be expected for proteins alone.
Design of a Phantom Mimicking Rectal Lymph Nodes for Magnetomotive Ultrasound.
Ultrasound Med Biol
January 2025
Article Synopsis
- - The study addresses the need for a reliable phantom to test the new magnetomotive ultrasound technique, specifically designed to simulate nanoparticle-laden lymph nodes in fat for rectal cancer staging.
- - A composite material was created using styrene-butylene/ethylene-styrene in mineral oil with glass beads, and included a polyvinyl alcohol insert with magnetic nanoparticles, which closely mimicked the acoustic properties of real lymph nodes and surrounding fat.
- - The resulting phantom showed stable performance and accurate reflection rates over three weeks, indicating its potential as a useful tool for validating the magnetomotive ultrasound method and possibly other tissue-mimicking applications.
