Article Abstract
Background And Aims: Obesity is a major risk factor for hypertension. The evidence on the effects of dietetic interventions to weight loss in blood pressure is scarce. Our main objective was to assess changes in blood pressure through 24-hours ambulatory blood pressure monitoring (ABPM) in different hypocaloric diets differing in their theoretical ketogenic potential.
Methods: In this single-centre, parallel-group randomized controlled trial (NCT04453150), participants with obesity (body mass index of more than 30kg/m2) were randomly assigned to one of five dietetic interventions: early time-restricted eating (eTRE), evening time-restricted eating (lTRE), modified alternate-day fasting (mADF), ketogenic diet (KD), and a control group following a standard Mediterranean diet (CG). In this subanalysis, a total of 96 participants were included and underwent 24-h ABPM before and after the intervention.
Results: All groups showed statistically significant changes in anthropometric parameters. Regarding ABPM, mADF showed greater changes with improvements in most of the ABPM parameters after the intervention. Also, lTRE showed some improvements after the intervention while the rest of the groups did not show any statistically significant change. In the linear mixed model, the mADF diet appeared to have an influence on the improvement in 24-hour systolic blood pressure.
Conclusions: Diets with different ketogenic potential aimed to weight loss have different effectiveness in reducing blood pressure. mADF was the best approach regardless of changes in body composition or ketone production.

Blood pressure variability (BPV), independent of mean BP, is an emerging predictor of cardiovascular risk and hypertension-mediated organ damage. However, its clinical utility remains limited due to the lack of clear guideline recommendations, leading to variability in physician practices. Using the modified Delphi method, this is the first Egyptian consensus to provide expert recommendations for integrating BPV in Egypt's resource-limited settings.

Background: Postoperative cognitive dysfunction (POCD) occurs in 20% to 80% of patients following cardiac surgical interventions. The incidence of delirium is from 20% to 50%. Impaired cerebral autoregulation (CA) during cardiopulmonary bypass (CPB) contributes to these issues.

This study aims to fill this gap by leveraging Global Burden of Disease 2021 (GBD 2021) data to conduct a comprehensive assessment of the disease burden attributable to high systolic blood pressure (SBP) in young adults. Data from the Global Health Data Exchange were utilized to estimate the disease burden attributable to high SBP in young adults, stratified by overall disease, sex, socio-demographic index (SDI) level, GBD region, nation, and specific disease. In 2021, the overall disease attributable to high SBP in young adults was substantial, with approximately 24,626,362 disability-adjusted life years (DALYs) and 477,992 deaths, and the DALYs and mortality rates were 623.

Objectives: Elevated intracranial pressure (ICP) is a complication of severe traumatic brain injury (TBI) that carries a risk of secondary brain injury. This study investigated the association between ICP burden and brain injury patterns on MRI in children with severe TBI.
Design, Setting, And Patients: Secondary analysis of the Approaches and Decisions in Acute Pediatric TBI (ADAPT) study, which included children with severe TBI (Glasgow Coma Scale score < 9) who received a clinical MRI within 30 days of injury.
