Characteristics, causes and impact of headache among a sample of physicians working during COVID-19 pandemic.

Background: Headache is considered a common health problem affecting physicians during Coronavirus disease-19 (COVID-19) pandemic and has direct impact on their productivity. Wearing personal protective equipment (PPE), stress and lack of sleep are common factors affecting their headache.

Results: Out of 165 participants, 38(23%) experienced new onset headache.

Purification of rad-waste arising from irradiated natural tin target towards tellurium-125m/antimony-125 radioisotope generator elaboration.

The present study introduces a new approach based on an irradiated tin target's impurity to produce aSb/Te radioisotope generator. A prepared generator gel matrix of zirconium-silico-tungstate was loaded with 6660 MBq (180 mCi) activity of the separated antimony. The loading and elution method has been studied as a function of the concentration of HSO acid solution.

Multidisciplinary assessment of patients with ischemic stroke, the structure of a stroke team, and first Egyptian experience in adults undergoing transcatheter PFO closure for PFO-related stroke.

Background: Patent foramen ovale closure in the setting of stroke was debatable until the recent data from the long-term follow-up of multiple randomized control trials. These recent data have led to increase the number of the procedure worldwide. To our knowledge, there was no previous formal structured program in Egypt between cardiologists and neurologists for investigation and management of patients with cryptogenic stroke.

Kidney injury molecule-1/creatinine as a urinary biomarker of acute kidney injury in critically ill neonates.

Introduction: Acute kidney injury (AKI) is a complex disorder, means acute deterioration of renal function generally occurring over hours to days. Serum creatinine (SCr) is a suboptimal biomarker in neonates as the creatinine concentration reflects the maternal level for up to 72 h after birth, to improve the ability for early prediction of AKI and improve clinical outcomes, there has been a significant amount of research to identify novel biomarkers of damage to allow for the earlier identification of neonates with AKI.

Objective: This study aimed to study the effectiveness of urinary kidney injury molecule-1/creatinine (uKIM-1/cr) in the diagnosis of AKI in critically ill neonates.

Plasma cystatin C versus renal resistive index as early predictors of acute kidney injury in critically ill neonates.

Introduction: Acute kidney injury (AKI) independently predicts morbidity and mortality of critically ill neonates. Serum cystatin C is a promising early biomarker for AKI. Evaluating the renal resistive index (RRI) by Doppler ultrasound demonstrates abnormal intrarenal vascular impendence.
