Article Abstract

Objective: Micro-nutrients are closely related to pulmonary tuberculosis (PTB). Most patients with PTB suffer from micro-nutrients deficiency. We aimed to evaluate the efficacy of micro-nutrients support on clinical therapy and chronic inflammation in patients with PTB.

Methods: We searched Pubmed, Springer link, Web of Science, Cochrane, Wan Fang and CNKI databases for randomised controlled trials (RCTs). The patients with anti-TB treatments were divided into two groups, the control group with nutritional advice or placebo, and the experimental group with micro-nutrients support for more than 2 weeks. Two reviewers conducted data extraction and quality assessment of the studies independently, and ReviewManager 5.2 software was used to input and analyse the data. The dichotomous variable was expressed in the risk ratios (RRS) and 95% CI, the continuous data were expressed in the mean difference (MD) and 95% CI, and the heterogeneity of subgroup was evaluated by I (Kerantzas and Jacobs, Jr., 2017) [2] test.

Results: A total of 13 trials (2847 participants) were included. First, micro-nutrients improved sputum smears or culture negative conversion rates (OR 0.16 0.03-0.77, 2.29; MD -2.36, -4.72~-0.01, z = 1.97). Meanwhile, micro-nutrients support increased lymphocytes and decreased leukocytes, neutrophils, CRP and ESR (MD 0.20, 0.06-0.35, z = 2.78; MD -0.42, -0.65~-0.18, z = 3.48; MD -0.66, -1.12~-0.20, z = 2.82). However it had not impact on body weight, MUAC, haemoglobin, albumin or monocytes (p > 0.05).

Conclusion: Micro-nutrients support can reduce chronic inflammation and improve sputum smears or culture conversions to contribute to anti-TB treatment.

Kidney transplant recipients face a substantial burden of premature mortality and morbidity, primarily due to persistent inflammation, cardiovascular risk, and nutritional deficiencies. Traditional nutritional interventions in this population have either focused on supplementing individual nutrients-often with limited efficacy-or required comprehensive dietary overhauls that compromise patient adherence. In this narrative review, we explore the rationale for dietary nut enrichment as a feasible, multi-nutrient strategy tailored to the needs of kidney transplant recipients.

On earth, soil is one of the most essential parts of nature which plays critical roles in plant growth, water flow, waste products recycling and provides habitats to various organisms. Soil is the combination of organic matter, air, water minerals, and sixteen different essential nutrient elements which are categorized into primary macronutrients, secondary macronutrients, and micronutrients. The nutrients elements present in soil either in organic forms or organic forms interchanged by the various microbial mechanisms such including fixation, chelation and solubilization.

Background/objectives: this study evaluated the differential effects of two distinct dietary nucleotide supplements, combined with spontaneous physical activity, on neuromuscular, cognitive, and metabolic adaptations in older adults.

Methods: Sixty-nine physically independent older adults (aged 60-75 years) were randomly assigned to three groups: (1) a yeast nucleotides formulation (YN) standardized in a high content of free nucleotides (>40%) rich in all macro and micro nutrients naturally occurring in yeast cell (amino acids, minerals and B-group vitamin); (2) a neuro-based formulation (NF) consisting of a blend of monophosphate nucleotides 5'; or (3) a placebo. Participants maintained their spontaneous physical activities without structured exercise during a 10-week intervention.

Background: Epidemiological evidence suggests a link between the risk of IBD and diet. Macro- and micro- nutrient intake, diet quality and dietary patterns may play a pivotal role in disease pathogenesis. We aimed to study the dietary intake of newly diagnosed IBD patients compared to non-IBD controls.

Fruits and vegetables (FVs) are rich sources of macro and micro-nutrients crucial for a healthy diet. In addition to these nutrients, FVs also contain fibre and phytochemicals known for their antioxidant properties. Despite the growing evidence of the disease-preventive role of antioxidants in FVs, their bioavailability and bioaccessibility vary significantly and have not been adequately explored.
