Background: Tuberculosis (TB) remains a significant global health challenge, with malnutrition being a key risk factor for poor outcomes. This study aimed to evaluate the impact of nutritional supplementation on treatment outcomes in drug-sensitive pulmonary tuberculosis (DS-PTB) patients and explore patient perspectives on nutrition during TB treatment.
Methods: We conducted a mixed methods study in the Jamnagar district of Gujarat, India. The quantitative component was a retrospective cohort study comparing 645 DS-PTB patients who received nutritional supplements with 645 patients who did not. The primary outcomes were cure rates, mortality, and weight gain. Qualitative data were collected through in-depth interviews of 240 patients to explore their experiences and perceptions regarding nutrition during TB treatment.
Results: Patients receiving nutritional supplements had significantly higher cure rates (482/645, n=74.7% vs 328/645, n=50.9%, OR: 2.86, 95% CI: 2.26-3.61, p<0.001) and lower mortality (7/645, n=1.1% vs 37/645, n=5.7%, OR: 0.18, 95% CI: 0.08-0.41, p<0.001) compared to the non-supplemented group. The group that received nutritional supplementation showed greater weight gain over six months (6.5 kg vs 3.1 kg, p<0.001). Qualitative findings revealed that patients who received nutritional supplementation reported improved appetite, increased energy, and faster symptom resolution while control group participants faced financial constraints and reduced appetite as barriers to adequate nutrition.
Conclusion: Nutritional supplementation significantly improved treatment outcomes in DS-PTB patients, including higher cure rates, reduced mortality, and enhanced weight gain. Patient perspectives highlighted the multifaceted impact of nutritional support. These findings suggest that integrating nutritional supplementation into standard TB care could substantially improve patient outcomes and experiences.

This study aimed to investigate the effects of dietary isatidis root polysaccharide (IRP) on diarrhea, immunity, and intestinal health in weanling piglets. Forty healthy piglets were randomly assigned to five groups receiving varying dosages of IRP. The findings indicated that different concentrations of IRP significantly reduced diarrhea scores ( < 0.

Background: Consuming prebiotics demonstrated therapeutic potential against obesity, as illustrated by our previous study on xylooligosaccharide (XOS), revealing that XOS reduced adiposity, diminished systemic inflammation, and restored cognitive function in obese insulin-resistant rats through the gut-brain axis. Fresh bananas at various ripening stages are being transformed into snacks, indicating potential as prebiotic-based treats enriched with fructooligosaccharide and inulin. Despite those findings, there remains a notable gap in the literature concerning the impact of these prebiotic-based snacks on brain inflammation, reactive oxygen species (ROS) production, and cognitive function in high-fat diet (HFD)-induced obese rats.

Background: Myocardial infarction (MI) is a leading cause of death while those surviving MI are still at risk of developing dementias. Alzheimer's disease (AD) is the leading cause of dementia currently without a cure or an effective prevention even in vulnerable subpopulations. Both AD and MI are common causes of disabilities and deaths in aging populations.

Background: Cerebral amyloid angiopathy (CAA), characterized by the accumulation of amyloid protein in the cerebral vasculature, is highly prevalent in Alzheimer's disease (AD) patients and, on its own, increases the risk of hemorrhagic stroke, cognitive impairment, and dementia. Currently, there are no effective ways to treat or prevent CAA. Ketogenic diet (KD), characterized by high-fat, low-carbohydrate, and moderate amounts of protein consumption, has gained considerable attention in recent years for its potential therapeutic use in patients with neurodegenerative diseases, including Alzheimer's disease.
