The COVID-19 pandemic has had a profound impact globally, particularly in high-risk populations such as those with underlying health conditions. In response to the evolving pandemic landscape and the recent surge in confirmed cases in Taiwan, the Taiwan Association of Family Medicine (TAFM) established a consensus on COVID-19 vaccine recommendations for vulnerable groups through a comprehensive literature review, expert panel discussions, and a practice-oriented formulation procedure to develop evidence-based guidance. Its key findings highlight the increased risk of severe COVID-19 outcomes among individuals with disorders such as diabetes, obesity, chronic kidney disease, cardiovascular disease, and respiratory illness.

Acute lung injury (ALI) is a difficult condition to manage, especially when it is complicated by bacterial sepsis. Hibifolin, a flavonoid glycoside, has anti-inflammatory properties that make it a potential treatment for ALI. However, more research is needed to determine its effectiveness in LPS-induced ALI.

Article Synopsis
  • * Data from the TriNetX US Collaboratory network was analyzed, comparing infection risks, healthcare utilization, and mortality between patients vaccinated within three months of chemotherapy and those who waited longer.
  • * Results showed that vaccinations within three months significantly increased risks for COVID-19, urinary tract infections, sepsis, and hospital stays, suggesting that waiting three months post-chemotherapy is beneficial for reducing health complications.

SARS-CoV-2, the etiological agent of COVID-19, is devoid of any metabolic capacity; therefore, it is critical for the viral pathogen to hijack host cellular metabolic machinery for its replication and propagation. This single-stranded RNA virus with a 29.9 kb genome encodes 14 open reading frames (ORFs) and initiates a plethora of virus-host protein-protein interactions in the human body.

The purpose of this study was to investigate the nutritional status of dementia patients and examine the correlation with sarcopenia, frailty, depression, and quality of life. We enrolled patients aged 60 years and over with Mini Mental State Examination (MMSE) scores ≤ 26 (Taiwan), and dementia diagnosed by a neurologist or psychiatrist. Nutritional status was assessed with the Mini Nutritional Assessment (MNA).

This study was conducted to investigate the β-carotene status in osteoarthritis (OA) patients and examine its relationships with the risk of inflammation and metabolic syndrome. OA patients were stratified by obesity based on body fat percentage (obese OA, = 44; non-obese OA, = 56), and sixty-nine subjects without OA or obesity were assigned as a non-obese control group. β-carotene, metabolic parameters, and inflammation status were assessed.

Lung adenocarcinoma (LADC) is the most common subtype of lung cancer worldwide and the epidermal growth factor receptor (EGFR) has a great influence on its clinical course, mainly due to the influence of different phenotypes. The Aurora kinase A (AURKA) would influence the progression of several solid malignancies. However, whether the interaction between EGFR phenotypes and AURKA would influence the clinical characteristics of LADC remains unknown.

Ubiquinone is a lipid antioxidant, and a novel liquid ubiquinol (a hydro-soluble, reduced form of coenzyme Q10) supplement was recently developed. The purpose of this study was to examine the levels of glucose, lipids and antioxidant capacity of type 2 diabetes patients after liquid ubiquinol supplementation. This study was designed as a randomised, double-blind, placebo-controlled trial.

Background And Purpose: Prolonged sitting is associated with increased risk of sarcopenia in community-dwelling older adults and can lead to poor muscle function, limited balance and transfer abilities, and mobility limitations. Sitting time can be a modifiable factor in preserving independent mobility in older adults. Assessing sitting time is an important measure for preventive medicine in older populations.

Previous studies have shown that mulberry water extracts (MWEs), which contain polyphenolic compounds, have an antiatherosclerotic effect in vivo and in vitro through stimulating apoptosis of vascular smooth muscle cells (VSMCs). Histological analysis was performed on atherosclerotic lesions from high-cholesterol diet (HCD)-fed rabbits after treatment with 0.5-1% MWEs for 10 weeks.

This study was aimed to investigate the effects of water extracts of Graptopetalum paraguayense (WGP, 4 g/d) on blood pressure, blood glucose level, and lipid profiles in subjects with metabolic syndrome (MS). Participants with MS (n = 54) were randomly assigned to the placebo (n = 28) and WGP groups (n = 26), and the intervention was administered for 12 weeks. Systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose (FG), lipid profiles (total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein (HDL-C)), and antioxidant enzymes activities (catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx)) were measured.
