The vulnerable atherosclerotic plaque is associated with an increased number of acute coronary syndromes. Current techniques such as coronary angiography are unable to detect and prospectively evaluate these lesions. Recently, other techniques, both invasive and noninvasive, are being developed trying to detect the plaque that is at increased risk for rupture eventually resulting in increased thrombosis. This review describes briefly evolving techniques for imaging of vulnerable plaques and describes in detail intravascular thermography.

Peripheral DNA Methylation of Cortisol- and Serotonin-Related Genes Predicts Hippocampal Volume in a Pediatric Population.
Biol Psychiatry Glob Open Sci
March 2025
Department of Psychology, Arizona State University, Tempe, Arizona.
Background: Hippocampal volume increases throughout early development and is an important indicator of cognitive abilities and mental health. However, hippocampal development is highly vulnerable to exposures during development, as seen by smaller hippocampal volume and differential epigenetic programming in genes implicated in mental health. However, few studies have investigated hippocampal volume in relation to the peripheral epigenome across development, and even less is known about potential genetic moderators.

Bihar Rural Livelihoods Promotion Society (BRLPS) "JEEVIKA", Patna Bihar, India.
Background: Rural populations in Bihar, India, face significant healthcare access challenges due to geographical, infrastructural, and financial barriers. The Swasthya Mitra program, initiated by the Bihar Rural Livelihood Promotion Society in collaboration with local and international partners, aims to mitigate these challenges by employing trained community members to navigate patients through the healthcare system.
Methods: This qualitative study employed in-depth interview and thematic analysis to evaluate the Swasthya Mitra program in the Bhagalpur and Jamui districts in Bihar, India.
COMPUTED TOMOGRAPHY CEREBRAL PERFUSION TO PREDICT FUNCTIONAL OUTCOME IN PAEDIATRIC HEAD INJURY: A COMPARITIVE STUDY OF VOXEL BASED AND WHOLE BRAIN PERFUSION.

Department of Neurosurgery, SMS Medical College and Hospital, Jaipur, Rajasthan, India.
Objective: This study evaluates the extent of perfusion abnormalities in pediatric traumatic head injury patients by using computed tomography perfusion (CTP) and compares the efficacy of voxel based and whole brain perfusion data clinically with functional outcome scales GOSE-P and MRS.
Methodology: In this Prospective study 100 eligible patients of age group 0-15 years were enrolled. Subjects were categorized into mild, moderate and severe traumatic brain injury using GCS.
Histopathology and proteomics are synergistic for high-grade serous ovarian cancer platinum response prediction.

Patients with High-Grade Serous Ovarian Cancer (HGSOC) exhibit varied responses to treatment, with 20-30% showing de novo resistance to platinum-based chemotherapy. While hematoxylin-eosin (H&E)-stained pathological slides are used for routine diagnosis of cancer type, they may also contain diagnostically useful information about treatment response. Our study demonstrates that combining H&E-stained whole slide images (WSIs) with proteomic signatures using a multimodal deep learning framework significantly improves the prediction of platinum response in both discovery and validation cohorts.

Background/objectives: For low- and middle- income country (LMIC) settings, a global nutrition transition is rapidly emerging as diets shift, resulting in a dual burden of malnutrition. High quality dietary intake data for these populations is essential to understand dietary patterns contributing to these nutrition issues. New technology is emerging to address dietary assessment challenges; however, it is unknown how researchers conducting studies with LMIC populations or under-served groups in high-income countries adopt technology-assisted methods.
