A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, Volume 30, Issue 2, Page 245-253, April 2026.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans

Advanced Science, Volume 13, Issue 19, 2 April 2026.
Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...

Creative and Adaptive Solutions for Early Diagnosis of Sickle Cell Disease in Sub‐Saharan Africa

American Journal of Hematology, Volume 101, Issue S1, Page 17-32, April 2026.
ABSTRACT Many of the children with sickle cell disease born in sub‐Saharan Africa remain undiagnosed and untreated. Increasing capacity and infrastructure to support diagnostic and screening programs in high income countries have enabled near universal survival into adulthood.

Hyperviscosity‐Related Ischemic Stroke in an Adolescent With Unrepaired Tetralogy of Fallot: A Case Report From a Resource‐Limited Setting

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. Chronic hypoxemia in uncorrected TOF causes compensatory erythrocytosis and hyperviscosity, predisposing to cerebrovascular complications. Stroke in this context is rare but clinically significant, especially in resource‐limited settings where access to imaging and
