Background: Early identification and treatment of non-alcoholic fatty liver disease (NAFLD) could reduce overall mortality. Anthropometric measurements offer a simple and cost-effective method to potentially improve early detection of NAFLD and prevent its complications. This study aims to estimate the prevalence of NAFLD using the fatty liver index (FLI) and evaluate the effectiveness of certain anthropometric measurements in predicting NAFLD as diagnosed by FLI.

Background: It is well-established that specific herbal plants contain natural active ingredients that have demonstrated anti-cancer potential. Therefore, they are considered highly beneficial as a potential adjuvant, alternative or complementary agent in anti-cancer therapy. However, the low chemical stability and limited bioavailability of 3, 3'-Diindolylmethane (DIM), a plant-derived compound used in clinical settings, limit its therapeutic applications.

Article Synopsis
  • Curcumin nanoparticles (Cur-NPs) were developed using PEG/chitosan to enhance the therapeutic effects of curcumin on liver cancer cells, which typically face limitations due to low pharmacologic profiles.
  • In tests, Cur-NPs showed cytotoxic effects on liver cancer cells (HepG2 and Huh 7) at concentrations as low as 6.25 µg/mL and inhibited cell migration significantly at higher doses.
  • The treatment led to decreased cell growth and induced apoptosis by altering the expression of critical proteins, promoting pro-apoptotic pathways while suppressing anti-apoptotic signals in liver cancer cells.

Background: In recent years, Saudi Arabia has witnessed staggering rates of hypertension and dyslipidemia-related cardiovascular (CV) deaths, overburdening the healthcare ecosystem of the country. Appropriate public health interventions can be devised through quantitative mapping of evidence. Identification of potential data gaps can prioritize future research needs and develop a 'best-fit' framework for patient-centric management of hypertension and dyslipidemia.

The presence of COVID-19 antibodies in the maternal circulation is assumed to be protective for newborns against SARS-CoV-2 infection. We investigated whether maternal COVID-19 antibodies crossed the transplacental barrier and whether there was any difference in the hematological parameters of neonates born to mothers who recovered from COVID-19 during pregnancy. The cross-sectional study was conducted at the Saidu Group of Teaching Hospitals, located in Swat, Khyber Pakhtunkhwa.

Evidence shows that the risk perception of humans can significantly affect their response to a threat. This population-based, cross-sectional study explored the determinants of perceived disease seriousness, perceived disease infectiveness, and perceived prevention self-efficacy of coronavirus disease (COVID-19), during the lockdown period, using the health belief model for preventive behavior (HBMPB) among 4423 adults in Saudi Arabia from 13 provinces. Multivariate binary regression was used to analyze the independent factors of three risk perception variables and to measure their effect on adherence to preventive measures.

Article Synopsis
  • - Several natural therapies, including curcumin, vitamin C, and eggshell membrane (ESM), are effective in preventing cell aging and promoting skin health by providing antioxidants and anti-inflammatory benefits.
  • - A study designed bio-polymeric foaming beads that encapsulate herbal extracts (alginate, Aloe vera, and orange peel) with ESM to enhance the sustained release of beneficial molecules for anti-aging effects.
  • - Tests on these foaming beads showed good structural integrity and their potential effectiveness in reducing oxidative stress and inflammation while proving safe for cells, suggesting they could be practical natural remedies for aging.

Phytochemicals extracted from plant sources have potential remedial effects to cure a broad range of acute to severe illnesses and ailments. Quercetin is a flavonoid isolated from different dietary sources such as vegetables and fruits, exhibiting strong anti-inflammatory, anti-oxidative and non-toxic effects on the biological system. However, the direct uptake or administration of quercetin results in loss of functionality, poor activity, and reduced shelf-life of the bioactive component.

Type 2 diabetes mellitus (T2DM) is a multifactorial disease with a high global incidence. Hypertriglyceridemia is a major risk factor for both cardiovascular disease and T2DM. In this study, we determined the allele and genotype frequencies of apolipoprotein A5 () single nucleotide polymorphism (SNP) rs662799 and perilipin 1 () SNPs rs894160, rs6496589, and rs1052700 and evaluated their association with T2DM risk in western Saudis.

Background: Obesity and type 2 diabetes (T2DM) are increasing in Saudi Arabia (SA). Among other conditions, these risk factors increase the likelihood of non-alcoholic fatty liver disease (NAFLD), which in turn increases risks for advanced liver diseases, such as non-alcoholic steatohepatitis (NASH), cirrhosis and cancer. The goal of this study was to quantify the health and economic burden of obesity-attributable T2DM and liver disease in SA.
