Abstract
Since the early 20th century, it has been known that Vitamin C plays a role in human health and susceptibility to infections. Studies show that for specific population groups, the duration of the common cold can be reduced with increased Vitamin C intake. It has also been shown to reduce the length of stay in intensive care units and use of mechanical ventilation by 8% with administration of 1-3g of Vitamin C daily. This NED Infobite highlights some of the latest research into Vitamin C and the immune system, focusing in particular on infections, ICU stays and need for mechanical ventilation.

Abstract
The exact causes of migraine headaches are still unknown. It seems likely that the aetiology is multi-factorial. This NED Infobite includes studies looking at anti-inflammatory agents such as curcumin and omega-3's, the impacts of optimising Vitamin D and partaking exercise and how targeting overweight and obesity may also reduce the frequency and duration of migraines.

Plain language summary
Aging is associated with a decline in physiological and physical function resulting in reduced physical activity, all of which are driving factors to the onset of chronic diseases and physical impairment. Older adults are often deficient in micronutrients, specifically vitamin D, which has been shown to have detrimental effects on the immune system, inflammatory and healing processes of fractured bones and also cardiovascular health beyond other musculoskeletal effects. The aim of this study was to investigate the effect of different vitamin D regimens in older individuals during an ongoing strength training period of 10 weeks while receiving vitamin D supplementation at the recommended level of 800 IU per day vs. a single dose of 50.000 IU per month. The data presented in this paper are part of the NutriAging Vitamin D study. The study was a randomised placebo-controlled double-blind trial which recruited one hundred community-dwelling women and men (aged 65–85 years). Participants were randomly allocated into three intervention groups, either the control group, the vitamin D daily (VDD) or the vitamin D monthly group (VDM). Results showed that oxidative stress might have played a role in the detrimental progress on chromosomal stability parameters since the protective effect of GSH (reduced glutathione) was reduced in all study groups at the end of the intervention, but the least reduction occurred in the VDD group. Authors concluded that a supplementation with the recommended dose of 800 IU vitamin D per day might be more advantageous when it comes to chromosomal stability parameters in older, formerly untrained participants undergoing demanding resistance exercise for 10 weeks.
Abstract
Older adults lack of proper physical activity which is often accompanied by vitamin D deficiency. Those factors are known to contribute to health issues in the later years of life. The main goal of this intervention study was to investigate the effect of different vitamin D supplementation strategies for 4 weeks solely or combined with a 10-week strength training program on chromosomal stability in peripheral blood mononuclear cells in community-dwelling older people. One hundred women and men (65-85 years) received either vitamin D3 daily (800 IU), a monthly dose (50.000 IU) or placebo for 17 weeks. All groups received 400 mg calcium daily. The fitness status of the study participants was measured using the 30- second chair stand test, the handgrip strength test and the 6-min walk test. The cytokinesis block micronucleus cytome (CBMN) assay was applied to analyze chromosomal anomalies, including cytotoxic and genotoxic parameters. Changes in antioxidant markers were measured in plasma. Walking distance and chair stand performance improved significantly. Increased levels of the parameters of the CBMN assay were detected for all intervention groups at study end. At baseline micronuclei (MNi) frequency correlated significantly with BMI in both sexes (females: r = 0.369, p = 0.034; males: r = 0.265, p = 0.035), but not with vitamin D serum levels. In females, body fat (r = 0.372, p < 0.001) and functional parameter using the 30-s chair stand test (r = 0.311, p = 0.002) correlated significantly with MNi frequency. Interestingly, not vitamin D supplementation but 10 weeks of resistance training increased MNi frequency indicating elevated chromosomal instability and also adverse effects on antioxidant markers including glutathione and FRAP were detected in the group of community-dwelling older adults.

Plain language summary
With the increase of age, the physiological reserve of the elderly decreases, which leads to the increase of physical vulnerability and the decrease of anti-stress ability, showing a series of frailty manifestations. Intrinsic capacity (refers to the comprehensive capacity of all physical and mental capacities of an individual) is central to maintaining function in older adults, and maintaining optimal intrinsic capacity is important to promote healthy aging. The aim of this study was to assess randomised controlled trials of multidomain interventions to further validate their effectiveness in the maintenance and enhancement of function in older adults, and to formulate strategies for preventive care and clinical practice. This study was a systematic review and meta-analysis of twenty-five publications. Results showed that multi-domain interventions can improve indicators of vital domains in older adults and integrate to optimise intrinsic capacity (refers to the comprehensive capacity of all physical and mental capacities of an individual) through potential interaction mechanisms. Authors concluded that because older adults may not be able to receive overly complex interventions due to limitations in their integrative abilities, the involvement of older adults and the sustainability of interventions should be considered before implementing them.
Abstract
Intrinsic capacity is central to the maintenance of function in older adults, and maintaining optimal intrinsic capacity is of great importance to promote healthy aging. The purpose of this systematic review and meta-analysis was to analyze the impact of multi-domain interventions on intrinsic capacity in older adults, intervention components, and potential interactions between components. A total of 6740 published articles were screened until August 2022, and the review included 25 randomized controlled trials that analyzed populations, interventions, control groups, and outcomes. The meta-analysis showed improvements in the primary outcome indicators in the intervention group compared to the control group. These included increased scores on the Mini-Mental State Examination as an indicator of cognitive function, decreased scores on the Geriatric Depression Scale (GDS-15) as an indicator of psychological ability and increased scores on the Short Physical Performance Battery (SPPB) as an indicator of physical performance, with only the SPPB indicator analyzed showing greater heterogeneity. Significant improvements were also seen in the secondary indicators Time-to-Walk Test (TUG), gait speed, Chair Stand Test (CST), grip strength values and BMI. There was insufficient data for the Mini Nutritional Assessment (MNA) as an indicator of vitality to conduct a meta-analysis. Studies were of moderate to high quality. The results of this review indicate that multi-domain interventions can maintain the level of intrinsic capacity in older adults and are equally effective in older adults with declining self-care abilities.
