Background: There is controversy regarding whether using fiber-enriched formula affects the incidence of diarrhea among enterally fed patients in our setting. Also, there is a lack of clinical studies about enterally fed patients' tolerance for feeding and the incidence of diarrhea among patients in the Middle East. This study aimed to assess fiber enrichment's efficacy in reducing post-enteral feeding bowel intolerance in non-critically ill patients.

NQO1 disruption enhances susceptibility to oxidative stress during hyperglycemia and is a significant contributor to the development and progression of diabetes. Oxidative stress has been linked to several symptoms, including hyperglycemia, reactive oxygen species buildup, high blood pressure, and the expression of inflammatory markers. Therefore, the present research aimed to evaluate the genetic abnormality of NQO1 (rs1800566, C609T) gene polymorphism, expression, and vitamin-D level assessment among Type 2 diabetes mellitus (T2DM) patients.

Article Synopsis
  • Diabetes is a chronic condition that can lead to complications affecting various body systems, and Ganoderma lucidum (G. lucidum) contains compounds showing potential benefits for diabetes management.
  • G. lucidum polysaccharides and triterpenoids have different mechanisms, including improving glucose metabolism and protecting pancreatic beta cells, which can help manage complications like diabetic nephropathy.
  • More research is needed to fully understand the active compounds in G. lucidum and how they work, with the goal of making it a viable, side-effect-free treatment option for diabetes.

In the present study, in vitro, in vivo, and in silico models were used to evaluate the therapeutic potential of Pulmeria alba methanolic (PAm) extract, and we identified the major phytocompound, apigetrin. Our in vitro studies revealed dose-dependent increased glucose uptake and inhibition of α-amylase (50% inhibitory concentration (IC)= 217.19 µg/mL), antioxidant (DPPH, ferric-reducing activity of plasma (FRAP), and lipid peroxidation (LPO) [IC = 103.

Alzheimer's disease (AD) is the most frequent type of dementia characterized by the deposition of amyloid beta (Aβ) plaque and tau-neurofibrillary tangles (TNTs) in the brain. AD is associated with the disturbances of various neurotransmitters including gamma-aminobutyric acid (GABA). Of note, GABA is reduced in AD, and restoration of GABA effect by benzodiazepines (BDZs) may improve AD outcomes.

Parkinson's disease (PD) is the second most frequent neurodegenerative brain disease (NBD) after Alzheimer's disease (AD). Statins are the most common lipid-lowering agents used in the management of dyslipidemia and the prevention of primary and secondary cardiovascular diseases (CVD) events. In addition, there is a controversial point regarding the role of serum lipids in the pathogenesis of PD.

Lung cancer is the second most commonly diagnosed cancer in the world. In terms of the diagnosis of lung cancer, combination carcinoembryonic antigen (CEA) and cancer antigen 125 (CA125) detection had higher sensitivity, specificity, and diagnostic odds ratios than CEA detection alone. Most individuals with elevated serum CA125 levels had lung cancer that was either in stage 3 or stage 4.

Apolipoprotein E (ApoE) is the main cholesterol carrier of the brain and the ε4 gene variant (APOE4) is the most prevalent genetic risk factor for Alzheimer's disease (AD), increasing risk up to 15-fold. Several studies indicate that APOE4 modulates critical factors for neuronal function, including brain-derived neurotrophic factor (BDNF) and peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α). Both proteins show exercise-induced upregulation, which is presumed to mediate many of the beneficial effects of physical activity including improved cognition; however, there is variability in results between individuals potentially in-part due to genetic variations including APOE isoform.

Alzheimer's disease (AD) is the most common type of dementia characterized by the deposition of amyloid beta (Aβ) plaques and tau-neurofibrillary tangles in the brain. Visceral obesity (VO) is usually associated with low-grade inflammation due to higher expression of pro-inflammatory cytokines by adipose tissue. The objective of the present review was to evaluate the potential link between VO and the development of AD.
