Did Primary Healthcare Patients in Riyadh Experience Their First Migraine Episodes After a Stressful Event, and What Triggers and Relievers Do They Commonly Report?

Objective: This study aimed to investigate whether the first onset of migraine episodes among primary healthcare patients in Riyadh, Saudi Arabia, is preceded by a highly stressful event, as well as to identify common potential triggers and relievers reported by these patients.

Background: Migraine is a prevalent and debilitating neurological disorder. The pathophysiology of migraine involves complex interactions between genetic, neurological, and environmental factors, including the trigeminovascular system and neuropeptides such as calcitonin gene-related peptide (CGRP).

Assessment of the services provided at the family medicine staff clinics in King Saud Medical City, Riyadh.

Background: Patient satisfaction is the subjective evaluation of a patient's cognitive and emotional responses. This reflects their expectations regarding the ideal healthcare to be provided. This study aims to assess the satisfaction level of the attendees to the family medicine staff clinics at King Saud Medical City, Riyadh.

Association of ACE1 I/D polymorphism and susceptibility to COVID-19 in Egyptian children and adolescents.

Background: Given the sparse data on the renin-angiotensin system (RAS) and its biological effector molecules ACE1 and ACE2 in pediatric COVID-19 cases, we investigated whether the ACE1 insertion/deletion (I/D) polymorphism could be a genetic marker for susceptibility to COVID-19 in Egyptian children and adolescents.

Methods: This was a case-control study included four hundred sixty patients diagnosed with COVID-19, and 460 well-matched healthy control children and adolescents. The I/D polymorphism (rs1799752) in the ACE1 gene was genotyped by polymerase chain reaction (PCR), meanwhile the ACE serum concentrations were assessed by ELISA.

Barriers of exclusive breastfeeding among mothers attending primary health-care centers in Jazan, Saudi Arabia.

Background: Exclusive breastfeeding (EBF) describes infants who were only breastfed for 6 months. Many Saudi mothers have suboptimal breastfeeding practices. Therefore, this study aims to assess breastfeeding knowledge and determine barriers to EBF among mothers attending primary health care centers in Jazan City.

Vitamin D deficiency and vitamin D receptor FokI polymorphism as risk factors for COVID-19.

Background: Given the sparse data on vitamin D status in pediatric COVID-19, we investigated whether vitamin D deficiency could be a risk factor for susceptibility to COVID-19 in Egyptian children and adolescents. We also investigated whether vitamin D receptor (VDR) FokI polymorphism could be a genetic marker for COVID-19 susceptibility.

Methods: One hundred and eighty patients diagnosed to have COVID-19 and 200 matched control children and adolescents were recruited.

Advantages of Small Incision Lenticule Extraction (SMILE) for Mass Eye and Ear Special Issue.

This review summarizes the advantages of Small-incision lenticule extraction (SMILE), including improved patient intraoperative experience, improved postoperative ocular surface, low incidence of regression, low re-treatment rates, and advantageous biomechanical corneal stability. Visual and refractive outcomes are similar to those achieved with LASIK, notably in large population studies. Since the inception of SMILE almost 10 years ago, the procedure has been rapidly growing in popularity.
