Predictive role of CHA₂DS₂-VASc score in acute coronary syndrome patients and value of adding global longitudinal strain to CHA₂DS₂-VASc score.

Background: Future clinical management would be improved by accurate and early identification of ACS patients at high CV risk. In non-valvular atrial fibrillation patients, the prognostic risk of thromboembolism has been evaluated using CHA₂DS₂-VASc scores. It has recently been shown to assess the severity of CAD and foresee patient outcomes.

Gastroesophageal Reflux Disease Among Undergraduate Medical Students in Egypt: Prevalence and Risk Factors.

Background: Gastroesophageal reflux disease (GERD) is a prevalent gastrointestinal condition that has a detrimental impact on one's quality of life because of acid reflux causing damage to the esophagus. Primary symptoms consist of heartburn and regurgitation, although patients may also encounter chest pain, nausea, and dysphagia. Medical students may be particularly susceptible due to stressful lifestyles and unhealthy habits.

Emerging roles of hydrogen sulfide-metabolizing enzymes in cancer.

Gasotransmitters play crucial roles in regulating many physiological processes, including cell signaling, cellular proliferation, angiogenesis, mitochondrial function, antioxidant production, nervous system functions and immune responses. Hydrogen sulfide (HS) is the most recently identified gasotransmitter, which is characterized by its biphasic behavior. At low concentrations, HS promotes cellular bioenergetics, whereas at high concentrations, it can exert cytotoxic effects.

Neurological and neurobehavioral effects of welders in Egypt exposed to manganese containing welding fumes.

Purpose: Welders are more likely to develop neurobehavioral disorders because of their exposure to neurotoxic metals such as manganese. This study aimed to measure the neurobehavioral performance of welders occupationally exposed to manganese at welding enterprises and its relationship with the workplace environment.

Methods: It is a comparative cross-sectional study carried out on 130 welders working at 50 welding enterprises in Menoufia governorate, Egypt, compared to 130 non-occupationally exposed controls.

Does HIV co-infection promote Echinococcus dissemination?

The influence of human immunodeficiency virus (HIV) on the severity of hepatic cystic echinococcosis (CE) is uncertain. HIV-modulated immune suppression may increase the risk of contracting CE with less self-limiting disease, more rapid progression, and a higher likelihood of complications. A 30-year-old male with concurrent, untreated HIV underwent surgery for two large, complicated hepatic CE cysts, which were replacing the right hemiliver, and innumerable peritoneal daughter cysts.
