Malnutrition in hospitalised adults is recognized as a challenging health concern that is associated with many adverse outcomes. Malnutrition screening and assessment are essential for all patients admitted to the hospital and are particularly important for adults who are vulnerable. The aim of this study was to determine whether specialised oral-nutritional supplements (S-ONS) benefits were further associated with measurable improvements in quality of life (QoL) domains during the post-hospitalisation period. This study was a post-hoc analysis of NOURISH trial data. The NOURISH trial was a multicentre, prospective, randomised, double-blind, placebo-controlled, parallel-group study. Six-hundred and twenty-two patients were included in the intent-to-treat analysis. Results showed that malnourished, older patients who received daily interventions with S-ONS (during hospital stay and for 90-day post-discharge) had significantly better QoL domain scores compared to those who received only placebo intervention. Specifically, there were significant differences in the QoL domains of mental health/ cognition, vitality, social functioning, and general health. Further, there were significant QoL differences for physical component, physical functioning, bodily pain, and emotional role. Authors concluded that among malnourished, hospitalised patients (aged 65 years and over), supplementation with S-ONS during the hospitalisation and 90-days post discharge resulted in improvements in QoL.
Abstract
BACKGROUND & AIMS Both during and after hospitalization, nutritional care with daily intake of oral nutritional supplements (ONS) improves health outcomes and decreases risk of mortality in malnourished older adults. In a post-hoc analysis of data from hospitalized older adults with malnutrition risk, we sought to determine whether consuming a specialized ONS (S-ONS) containing high protein and beta-hydroxy-beta-methylbutyrate (HMB) can also improve Quality of Life (QoL). METHODS We analyzed data from the NOURISH trial-a randomized, placebo-controlled, multi-center, double-blind study conducted in patients with congestive heart failure, acute myocardial infarction, pneumonia, or chronic obstructive pulmonary disease. Patients received standard care + S-ONS or placebo beverage (target 2 servings/day) during hospitalization and for 90 days post-discharge. SF-36 and EQ-5D QoL outcomes were assessed at 0-, 30-, 60-, and 90-days post-discharge. To account for the missing QoL observations (27.7%) due to patient dropout, we used multiple imputation. Data represent differences between least squares mean (LSM) values with 95% Confidence Intervals for groups receiving S-ONS or placebo treatments. RESULTS The study population consisted of 622 patients of mean age ±standard deviation: 77.9 ± 8.4 years and of whom 52.1% were females. Patients consuming placebo had lower (worse) QoL domain scores than did those consuming S-ONS. Specifically for the SF-36 health domain scores, group differences (placebo vs S-ONS) in LSM were significant for the mental component summary at day 90 (-4.23 [-7.75, -0.71]; p = 0.019), the domains of mental health at days 60 (-3.76 [-7.40, -0.12]; p = 0.043) and 90 (-4.88 [-8.41, -1.34]; p = 0.007), vitality at day 90 (-3.33 [-6.65, -0.01]; p = 0.049) and social functioning at day 90 (-4.02 [-7.48,-0.55]; p = 0.023). Compared to placebo, differences in LSM values for the SF-36 general health domain were significant with improvement in the S-ONS group at hospital discharge and beyond: day 0 (-2.72 [-5.33, -0.11]; p = 0.041), day 30 (-3.08 [-6.09, -0.08]; p = 0.044), day 60 (-3.95 [-7.13, -0.76]; p = 0.015), and day 90 (-4.56 [-7.74, -1.38]; p = 0.005). CONCLUSIONS In hospitalized older adults with cardiopulmonary diseases and evidence of poor nutritional status, daily intake of S-ONS compared to placebo improved post-discharge QoL scores for mental health/cognition, vitality, social functioning, and general health. These QoL benefits complement survival benefits found in the original NOURISH trial analysis. CLINICAL TRIAL REGISTRATION NCT01626742.

The Coronavirus Disease 2019 (COVID-19) caused hundreds of thousands of deaths, mostly in older adults. The aim of this study was to test whether a single oral high-dose of cholecalciferol (vitamin D3) administered within 72 hours after the diagnosis of COVID-19 improves, compared to standard-dose cholecalciferol, the 14-day overall survival among at-risk older adults who are positive to COVID-19. This study is an investigator-initiated, multicentre, open-label, parallel group, intent-to-treat, randomised controlled superiority clinical trial which involves the collaboration of 9 medical centres. Eligible participants (n=260) were randomly assigned to receive a single oral dose of either 400,000 IU (n=130) or 50,000 IU (n=130) cholecalciferol on the day of inclusion. Results show: - reduced overall mortality at day 14. - that high-dose cholecalciferol was safe and did not result in more frequent adverse effects compared to the standard dose. - that some benefits were also found on the 14-day mortality due to COVID-19 as well as on the overall mortality between day 6 and day 14. - that there was no evidence that the single high-dose vitamin D3 administered early in COVID-19 provided any benefit on overall mortality for up to 28 days. Authors conclude that high-dose oral cholecalciferol supplementation is a simple, safe, and inexpensive treatment which may be of interest as an adjuvant to provide a bridge to recovery for at-risk older adults facing the emergence of immune escape variants.
Abstract
BACKGROUND Vitamin D supplementation has been proposed as a treatment for Coronavirus Disease 2019 (COVID-19) based on experimental data and data from small and uncontrolled observational studies. The COvid19 and VITamin d TRIAL (COVIT-TRIAL) study was conducted to test whether a single oral high dose of cholecalciferol (vitamin D3) administered within 72 hours after the diagnosis of COVID-19 improves, compared to standard-dose cholecalciferol, the 14-day overall survival among at-risk older adults infected with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). METHODS AND FINDINGS This multicenter, randomized, controlled, open-label, superiority trial involved collaboration of 9 medical centers in France. Patients admitted to the hospital units or living in nursing homes adjacent to the investigator centers were eligible if they were ≥65 years, had SARS-CoV-2 infection of less than 3 days, and at least 1 COVID-19 worsening risk factor (among age ≥75 years, SpO2 ≤94%, or PaO2/FiO2 ≤300 mm Hg). Main noninclusion criteria were organ failure requiring ICU, SpO2 ≤92% despite 5 L/min oxygen, life expectancy <3 months, vitamin D supplementation >800 IU/day during the preceding month, and contraindications to vitamin D supplements. Eligible and consenting patients were randomly allocated to either a single oral high-dose (400,000 IU) or standard-dose (50,000 IU) cholecalciferol administered under medical supervision within 72 hours after the diagnosis of COVID-19. Participants and local study staff were not masked to the allocated treatment, but the Steering Committee and the Data and Safety Monitoring Board were masked to the randomization group and outcome data during the trial. The primary outcome was 14-day overall mortality. Between April 15 and December 17, 2020, of 1,207 patients who were assessed for eligibility in the COVIT-TRIAL study, 254 met eligibility criteria and formed the intention-to-treat population. The median age was 88 (IQR, 82 to 92) years, and 148 patients (58%) were women. Overall, 8 (6%) of 127 patients allocated to high-dose cholecalciferol, and 14 (11%) of 127 patients allocated to standard-dose cholecalciferol died within 14 days (adjusted hazard ratio = 0.39 [95% confidence interval [CI], 0.16 to 0.99], P = 0.049, after controlling for randomization strata [i.e., age, oxygen requirement, hospitalization, use of antibiotics, anti-infective drugs, and/or corticosteroids] and baseline imbalances in important prognostic factors [i.e., sex, ongoing cancers, profuse diarrhea, and delirium at baseline]). The number needed to treat for one person to benefit (NNTB) was 21 [NNTB 9 to ∞ to number needed to treat for one person to harm (NNTH) 46]. Apparent benefits were also found on 14-day mortality due to COVID-19 (7 (6%) deaths in high-dose group and 14 (11%) deaths in standard-dose group; adjusted hazard ratio = 0.33 [95% CI, 0.12 to 0.86], P = 0.02). The protective effect of the single oral high-dose administration was not sustained at 28 days (19 (15%) deaths in high-dose group and 21 (17%) deaths in standard-dose group; adjusted hazard ratio = 0.70 [95% CI, 0.36 to 1.36], P = 0.29). High-dose cholecalciferol did not result in more frequent adverse effects compared to the standard dose. The open-label design and limited study power are the main limitations of the study. CONCLUSIONS In this randomized controlled trial (RCT), we observed that the early administration of high-dose versus standard-dose vitamin D3 to at-risk older patients with COVID-19 improved overall mortality at day 14. The effect was no longer observed after 28 days. TRIAL REGISTRATION ClinicalTrials.gov NCT04344041.

Inflammatory bowel diseases (IBD), such as Crohn’s Disease and ulcerative colitis, are chronic gastrointestinal disorders with periods of exacerbation and remission. The disease develops as a result of an abnormal immune response in the gastrointestinal mucosa in genetically predisposed individuals exposed to certain environmental conditions. The primary aim of this study was to evaluate the effectiveness of oral sodium butyrate as an add-on to standard therapy in children and adolescents with newly diagnosed IBD. This study is a prospective, randomised, and placebo-controlled trial. Patients (n = 80) were randomised and assigned to one of two groups: group A received butyric acid at a dose of 150 mg, and group B received 150 mg placebo. Results show that supplementation with sodium butyrate to be ineffective in the add-on treatment of newly diagnosed children and adolescents with IBD. Furthermore, during the study, none of the participants reported adverse events. Authors conclude that the results of their study will contribute to further studies that will determine which patients with IBD may benefit from sodium butyrate supplementation. Further clinical trials on large groups of patients are needed to establish if IBD patients may benefit from sodium butyrate.
Abstract
BACKGROUND Butyric acid's effectiveness has not yet been assessed in the pediatric inflammatory bowel disease (IBD) population. This study aimed to evaluate the effectiveness of oral sodium butyrate as an add-on to standard therapy in children and adolescents with newly diagnosed IBD. METHODS This was a prospective, randomized, placebo-controlled multicenter study. Patients aged 6-18 years with colonic Crohn's disease or ulcerative colitis, who received standard therapy depending on the disease's severity, were randomized to receive 150 mg sodium butyrate twice a day (group A) or placebo (group B). The primary outcome was the difference in disease activity and fecal calprotectin concentration between the two study groups measured at 12 weeks of the study. RESULTS In total, 72 patients with initially active disease completed the study, 29 patients in group A and 43 in group B. At week 12 of the study, the majority of patients achieved remission. No difference in remission rate or median disease activity was found between the two groups (p = 0.37 and 0.31, respectively). None of the patients reported adverse events. CONCLUSIONS A 12-week supplementation with sodium butyrate, as adjunctive therapy, did not show efficacy in newly diagnosed children and adolescents with IBD.

Plain language summary
Mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS) is a major clinical entity encompassing mitochondrial diseases resulting from mitochondrial dysfunction. Stroke-like episodes, the most critical symptom of MELAS, are characterised by an abrupt onset of cortical neurological deficits with typical MRI abnormalities not conforming to the distribution of main arteries. The aim of this study was to evaluate the efficacy and safety of high-dose taurine supplementation for prevention of stroke-like episodes. This study is a multicentre, open-label, phase III trial with a total of 291 patients with MELAS. Results show that oral supplementation with high-dose taurine was effective in preventing stroke-like episodes. Furthermore, the 50% responder rate reached 80%, and the annual relapse rate of stroke-like episodes significantly decreased with concomitant increases in blood and cerebrospinal fluid taurine levels. Adverse events associated with taurine were observed among the participants, but no serious adverse events associated with taurine supplementation were reported. Authors conclude that oral high-dose taurine supplementation was effective and safe for the prevention of stroke-like episodes in patients with MELAS by ameliorating the modification defect in the first anticodon nucleotide of mitochondrial tRNA [transfer RNA – a small RNA molecule].
Abstract
OBJECTIVE The aim of this study was to evaluate the efficacy and safety of high-dose taurine supplementation for prevention of stroke-like episodes of MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes), a rare genetic disorder caused by point mutations in the mitochondrial DNA that lead to a taurine modification defect at the first anticodon nucleotide of mitochondrial tRNALeu(UUR), resulting in failure to decode codons accurately. METHODS After the nationwide survey of MELAS, we conducted a multicentre, open-label, phase III trial in which 10 patients with recurrent stroke-like episodes received high-dose taurine (9 g or 12 g per day) for 52 weeks. The primary endpoint was the complete prevention of stroke-like episodes during the evaluation period. The taurine modification rate of mitochondrial tRNALeu(UUR) was measured before and after the trial. RESULTS The proportion of patients who reached the primary endpoint (100% responder rate) was 60% (95% CI 26.2% to 87.8%). The 50% responder rate, that is, the number of patients achieving a 50% or greater reduction in frequency of stroke-like episodes, was 80% (95% CI 44.4% to 97.5%). Taurine reduced the annual relapse rate of stroke-like episodes from 2.22 to 0.72 (P=0.001). Five patients showed a significant increase in the taurine modification of mitochondrial tRNALeu(UUR) from peripheral blood leukocytes (P<0.05). No severe adverse events were associated with taurine. CONCLUSIONS The current study demonstrates that oral taurine supplementation can effectively reduce the recurrence of stroke-like episodes and increase taurine modification in mitochondrial tRNALeu(UUR) in MELAS.

Migraine is a functional disorder of the brain. Non-medical, non-pharmacological and pharmacological treatments are recommended for the prevention of migraine. The aim of this study was to evaluate the efficacy of a proprietary nutritional supplement containing a fixed combination of magnesium, riboflavin and Q10 as prophylactic treatment for migraine. This study is a randomized double-blind placebo controlled, multicentre trial. The study enrolled 173 participants for the baseline phase of which 130 were randomised to one of the two groups; supplement (n=64) or placebo (n=66). Results show a reduction of migraine pain and burden of disease after 3 months of treatment with the supplement. Patients rated the efficacy of the treatment significantly superior to placebo. Furthermore, abdominal discomfort and diarrhoea due to high amounts of magnesium were the main adverse events associated with the supplement. Authors conclude that the nutritional supplement had a trend towards statistical significance in the reduction of migraine days, probably due to being underpowered. Migraine symptoms and burden of disease, however, were statistically significantly reduced compared to placebo. Healthcare practitioners could use the results of this study to consider supplementation with the studied nutrients when working with migraine patients.
Abstract
BACKGROUND Non-medical, non-pharmacological and pharmacological treatments are recommended for the prevention of migraine. The purpose of this randomized double-blind placebo controlled, multicenter trial was to evaluate the efficacy of a proprietary nutritional supplement containing a fixed combination of magnesium, riboflavin and Q10 as prophylactic treatment for migraine. METHODS 130 adult migraineurs (age 18 - 65 years) with ≥ three migraine attacks per month were randomized into two treatment groups: dietary supplementation or placebo in a double-blind fashion. The treatment period was 3 months following a 4 week baseline period without prophylactic treatment. Patients were assessed before randomization and at the end of the 3-month-treatment-phase for days with migraine, migraine pain, burden of disease (HIT-6) and subjective evaluation of efficacy. RESULTS Migraine days per month declined from 6.2 days during the baseline period to 4.4 days at the end of the treatment with the supplement and from 6.2.days to 5.2 days in the placebo group (p = 0.23 compared to placebo). The intensity of migraine pain was significantly reduced in the supplement group compared to placebo (p = 0.03). The sum score of the HIT-6 questionnaire was reduced by 4.8 points from 61.9 to 57.1 compared to 2 points in the placebo-group (p = 0.01). The evaluation of efficacy by the patient was better in the supplementation group compared to placebo (p = 0.01). CONCLUSIONS Treatment with a proprietary supplement containing magnesium, riboflavin and Q10 (Migravent® in Germany, Dolovent® in USA) had an impact on migraine frequency which showed a trend towards statistical significance. Migraine symptoms and burden of disease, however, were statistically significantly reduced compared to placebo in patients with migraine attacks.

Elevated blood pressure (BP) is a major risk factor for coronary heart disease and stroke. This study aims to examine the association between a wide range of nutrients and BP using a systematic nutrient-wide association study (NWAS) approach. Data obtained from the cross-sectional International Study of Macro/Micro-nutrients and Blood Pressure (INTERMAP) were analysed. All foods and drinks, including supplements, from 24-hours dietary recalls as well as analytes from urine collection were recorded. Statistical analyses were then performed for the associations of 82 nutrients from food only, 73 nutrients from foods plus supplements, as well as 3 urinary electrolytes/electrolyte ratios with systolic and diastolic BP. The study found: direct associations between alcohol and urinary sodium/potassium ratio with systolic BP; inverse associations between dietary phosphorus, magnesium, non-heme iron, thiamin, folacin, and riboflavin with systolic BP; inverse associations between dietary folacin and riboflavin with diastolic BP; and inclusion of nutrients from supplements intake decreased the associations of folacin, thiamin and riboflavin intake with BP. Authors emphasised the importance of NWAS approach to identify the complex array of nutritional correlates of systolic and diastolic BP. Findings have a potential to represent causative relations that need to be further examined in observational and interventional studies.
Abstract
BACKGROUND A nutrient-wide approach may be useful to comprehensively test and validate associations between nutrients (derived from foods and supplements) and blood pressure (BP) in an unbiased manner. METHODS AND RESULTS Data from 4680 participants aged 40 to 59 years in the cross-sectional International Study of Macro/Micronutrients and Blood Pressure (INTERMAP) were stratified randomly into training and testing sets. US National Health and Nutrition Examination Survey (NHANES) four cross-sectional cohorts (1999-2000, 2001-2002, 2003-2004, 2005-2006) were used for external validation. We performed multiple linear regression analyses associating each of 82 nutrients and 3 urine electrolytes with systolic and diastolic BP in the INTERMAP training set. Significant findings were validated in the INTERMAP testing set and further in the NHANES cohorts (false discovery rate <5% in training, P<0.05 for internal and external validation). Among the validated nutrients, alcohol and urinary sodium-to-potassium ratio were directly associated with systolic BP, and dietary phosphorus, magnesium, iron, thiamin, folacin, and riboflavin were inversely associated with systolic BP. In addition, dietary folacin and riboflavin were inversely associated with diastolic BP. The absolute effect sizes in the validation data (NHANES) ranged from 0.97 mm Hg lower systolic BP (phosphorus) to 0.39 mm Hg lower systolic BP (thiamin) per 1-SD difference in nutrient variable. Inclusion of nutrient intake from supplements in addition to foods gave similar results for some nutrients, though it attenuated the associations of folacin, thiamin, and riboflavin intake with BP. CONCLUSIONS We identified significant inverse associations between B vitamins and BP, relationships hitherto poorly investigated. Our analyses represent a systematic unbiased approach to the evaluation and validation of nutrient-BP associations.
