Endemic Medicine Department, Faculty of Medicine, Helwan University, Cairo, Egypt; Liver Disease Research Center, College of Medicine, King Saud University, Riyadh 11411, Saudi Arabia. Electronic address:

Personalized medicine is an emerging field that provides novel approaches to disease's early diagnosis, prevention, treatment, and prognosis based on the patient's criteria in gene expression, environmental factors, lifestyle, and diet. To date, hepatocellular carcinoma (HCC) is a significant global health burden, with an increasing incidence and significant death rates, despite advancements in surveillance, diagnosis, and therapeutic approaches. The majority of HCC lesions develop in patients with liver cirrhosis, carrying the risks of mortality associated with both the tumor burden and the cirrhosis.

Article Synopsis
  • The study focused on elderly patients (70+) undergoing primary percutaneous coronary intervention (pPCI) for ST-elevation myocardial infarction (STEMI) at a tertiary center in Upper Egypt, highlighting a growing concern for cardiovascular disease in aging populations.
  • The research included data from 3,627 patients, finding that 15.9% were elderly, with significantly higher in-hospital mortality rates, particularly among octogenarians (23.3%) compared to younger patients (4%).
  • Elderly patients showed distinct clinical characteristics, such as higher rates of hypertension and chronic kidney disease, and were more likely to have severe complications post-procedure, emphasizing the need for tailored strategies in managing this demographic in cardiovascular care.

  • A 48-week study was conducted to evaluate the safety and effectiveness of the laxative lubiprostone in patients with metabolic dysfunction-associated steatotic liver disease (MASLD), showing promising results.
  • Lubiprostone significantly reduced liver fat content compared to placebo, although it did not significantly impact fibrosis scores or serum ALT levels.
  • While the treatment was generally tolerated, with only one case of severe diarrhea in the lubiprostone group, further research is needed to confirm its efficacy for MASLD.

Introduction: While many randomized controlled trials (RCTs) have demonstrated the positive effects of school-based programs in reducing body fat among children and teenagers, there is no conclusive evidence to indicate that one approach is superior to another, largely due to the lack of direct and indirect comparisons. This study evaluated the relative effectiveness of various school-based obesity prevention initiatives in improving body mass index (BMI) among children and adolescents using network meta-analysis.

Methods: Searches included four databases focusing on articles published in English between the years 2002 and 2024.

Unveiling the impact of pipe materials on water hammer in pressure pipelines: an experimental and numerical study.

Sci Rep

December 2024

Department of Mechanical Design, Faculty of Engineering, Helwan University, P.O. Box 11718, Mataria, Helmeiat-Elzaton, Cairo, Egypt.

Water hammer (WH) is a phenomenon characterized by the rapid opening or closing of valves or pumps in pipelines, resulting in a disruptive noise, intense vibrations, and potential damage to pipes, fittings, structures, and even human safety. While WH arresters are commonly employed to mitigate this issue in smaller plumbing systems, alternative solutions are required for larger applications like power plants. Researchers have proposed the utilization of pipe materials with a low modulus of elasticity in areas prone to WH events, as these materials possess the capability to absorb a significant portion of the resulting vibrations.
