Plain language summary
The occurrence of fractures and osteoporosis are significant concerns in elderly adults, as ageing remains one of the primary risk factors for these conditions. While the incidence of fracture and risk may vary, the incidence of fragility fractures significantly increases with advancing age, particularly after the age of 50 years. This study's aim was to evaluate the adherence, tolerability, and safety of calcium citrate administration in an "outpatient" population in routine clinical practice. This study was a non-interventional, prospective, multicentre study. Two-hundred and sixty-eight individuals (comprised 245 females (91.4%) and 23 males (8.6%)) were enrolled. Results showed a high rate of adherence to calcium citrate supplementation over a one-year period in osteopenic elderly subjects. Additionally, the incidence of adverse reactions was low (3.9%), further emphasizing the tolerability of calcium citrate. Authors concluded that future studies designed to assess the long-term impact of calcium citrate supplementation on hard endpoints, such as bone density, fractures/falls, quality of life measures and adherence are needed.

Summary Review:
Introduction
A non-interventional, prospective multicentre study was conducted to evaluate the adherence, safety, and tolerability of calcium citrate supplementation in elderly osteopenic subjects.
Method:
A total of 231 Caucasian female (91%) and male (8%) participants with a median age of 70 received 500mg of calcium citrate supplementation daily for one year. Adherence was assessed based on tolerability, compliance, and persistence. Safety evaluations included monitoring of adverse reactions (ARs), physical examinations, and clinical laboratory evaluations.
Results
A total of 222 out of 231 participants (96%) completed the study. Nine subjects did not return for assessments or complete their diaries.
The primary and secondary findings of this study were as follows:
- An average adherence of 91% of oral calcium citrate supplementation was observed which was higher than the reported reference rate of 57% (p = 0.0179).
- Subjects with adherence <80% experienced a higher frequency of adverse events compared to those with adherence >80% (32/77; 42% vs 16/145%, (p = 0.0001).
- Gastrointestinal ARs were the most commonly reported, with constipation comprising 50% of all reported ARs.
- Reductions in systolic (130.7 ± 16.9 mmHg to 127.9 ± 14.5 mmHg) (p = 0.0102) and diastolic blood pressure 79.5 ± 8.7 mmHg to 77.4 ± 8.6 mmHg (baseline to V2) (p = 0.0116) were observed from baseline to the second visit.
- Positive changes were also noted in nutritional status (p = 0.0116), circulatory system disorders (p = 0.0001), and muscles/skeleton disorders (p = 0.0067) from baseline to post-baseline visit.
Conclusion:
This study revealed a 91% adherence to calcium citrate supplementation over one year in older adults with osteopenia, Additionally, the 4% incidents of ARs reported were related to gastrointestinal disorders.
Clinical practice applications:
- The prevalence of osteoporosis rises as individuals age, with approximately 10% of women at 60 years, 20% at 70 years, and 40% at 80 years.
- Calcium supplementation, usually with vitamin D, is a recommended complement to other specific pharmacological treatments of osteoporosis.
- The safety of calcium supplements remains controversial regarding an increased risk of cardiovascular events. Therefore, it is essential to investigate the safety profile of calcium in these populations.
- This study reported adherence, tolerability, and safety of calcium citrate supplementation in osteopenic elderly patients with 4% of patients reporting gastrointestinal adverse effects.
Considerations for future research:
- This study was conducted on 91% Caucasian females and 8% males with a mean age of 70 years therefore, there is a need to include more male and Asian participants from various age groups in further research.
- Future studies are needed to assess the long-term impact of calcium citrate supplementation on bone density, fractures, and quality of life.
Abstract
BACKGROUND Osteoporosis is a common concern in the elderly that leads to fragile bones. Calcium supplementation plays a crucial role in improving bone health, reducing fracture risk, and supporting overall skeletal strength in this vulnerable population. However, there is conflicting evidence on the safety of calcium supplements in elderly individuals. AIM: The aim of this study was to evaluate the adherence, safety and tolerability of calcium citrate supplementation in elderly osteopenic subjects. METHODS In this non-interventional, prospective, multicenter study, subjects received daily 500 mg calcium citrate supplementation for up to one year. Adherence was calculated based on compliance and persistence. Safety was assessed through adverse reactions (ARs), deaths, and clinical laboratory evaluations. RESULTS A total of 268 Caucasian subjects (91.4% female, mean age 70 ± 4.5 years) participated in the study. Mean adherence to treatment was 76.6 ± 29.5% and half of subjects had an adherence of 91% and ~ 33% of participants achieved complete (100%) adherence. ARs were reported by nine (3.9%) subjects, primarily gastrointestinal disorders, with no serious ARs. The frequency of all adverse events (including ARs) was significantly higher in subjects with adherence of < 80% (41.6%; 32/77) vs. those with adherence ≥ 80% (11%; 16/145, p < 0.0001). Both systolic and diastolic blood pressure decreased from baseline to follow-up visit (change of -2.8 ± 13.9 mmHg, p = 0.0102 and -2.1 ± 10.4 mmHg, p = 0.0116, respectively). CONCLUSION This study demonstrated favorable adherence to calcium citrate supplementation in elderly osteopenic subjects. The occurrence of ARs, though generally mild, were associated with lower adherence to calcium supplementation.

Plain language summary
Malnutrition amongst the elderly and those who are hospitalised due to multiple illnesses is frequent and increases risk of death. There have however been studies to show that there may be a way of identifying individuals at risk of malnutrition through measurements of biological markers. Prealbumin is a protein made in the liver that has been shown in smaller trials to be a possible biomarker for individuals at risk of malnutrition. This large cohort study of 517 individuals aimed to determine if prealbumin was associated with death and if nutritional support would improve survival. The results showed that individuals who were at risk of malnutrition with low prealbumin levels had almost double the mortality rate after 6 months. However individualised nutritional support did not improve mortality. It was concluded that prealbumin is a prognostic marker for death in nutritionally at-risk patients but does not identify individuals who may respond to nutritional support. This study could be used by healthcare professionals to understand that prealbumin may be helpful in identifying mortality risk amongst individuals at risk of malnutrition but not those who may benefit from personalised nutrition recommendations.
Abstract
BACKGROUND Because of the shorter half-life as compared with albumin, serum prealbumin concentrations have been proposed to be useful nutrition biomarkers for the assessment of patients at nutrition risk. In a post hoc analysis of patients at nutrition risk from a randomized controlled nutrition trial, we tested the hypothesis that (1) prealbumin is associated with higher all-cause 180-day mortality rates and that (2) individualized nutrition support compared with usual-care nutrition more effectively improves survival at 30 days in patients with low prealbumin levels compared with patients with normal prealbumin levels. METHODS We performed a prespecified cohort study in patients included in the pragmatic, Swiss, multicenter randomized controlled EFFORT trial comparing the effects of individualized nutrition support with usual care. We studied low prealbumin concentrations (<0.17 g/L) in a subgroup of 517 patients from one participating center. RESULTS A total of 306 (59.2%) patients (mean age 71.9 years, 53.6% men) had low admission prealbumin levels (<0.17 g/L). There was a significant association between low prealbumin levels and mortality at 180 days (115/306 [37.6%] vs 47/211 [22.3%], fully adjusted hazard ratio [HR]=1.59, 95% CI 1.11-2.28; P = 0.011). Prealbumin levels significantly improved the prognostic value of the Nutritional Risk Screening total score regarding mortality prediction at short- and long-term. The difference in mortality between patients receiving individualized nutrition support and usual-care nutrition was similar for patients with low prealbumin levels compared with patients with normal prealbumin levels (HR=0.90 [95% CI=0.51-1.59] vs HR=0.88 [95% CI=0.35-2.23]) with no evidence for interaction (P = 0.823). CONCLUSION Among medical inpatients at nutrition risk, low admission prealbumin levels correlated with different nutrition markers and higher mortality risk, but patients with low or high prealbumin levels had a similar benefit from nutrition support. Further studies should identify nutrition markers that help further personalize nutrition interventions.

Plain language summary
Lifestyle interventions targeting diet are a possible approach that could affect public health. Most clinical trials have investigated comprehensive diets, in contrast to dietary manipulation of single foods or nutrients. The aim of this study was to evaluate the effects of a 3-year dietary intervention on cognitive decline and brain-imaging markers of dementia and Alzheimer’s disease in older, cognitively unimpaired adults at risk for dementia because of family history. This study was a 3-year, two-site, randomised, controlled trial. The participants were randomly assigned to follow the MIND diet with mild caloric restriction for weight loss or their usual diet with the same mild caloric restriction for weight loss (control diet). Participants were randomly assigned in a 1:1 ratio. Results showed that the participants who followed the MIND diet had small improvements in a global measure of cognition that were similar to those who followed a control diet with mild caloric restriction. Authors concluded that brain health, cognitive function and brain imaging outcomes (after 3 years) did not differ significantly between participants who followed the MIND diet and those who followed a control diet with a mild caloric restriction.
Abstract
BACKGROUND Findings from observational studies suggest that dietary patterns may offer protective benefits against cognitive decline, but data from clinical trials are limited. The Mediterranean-DASH Intervention for Neurodegenerative Delay, known as the MIND diet, is a hybrid of the Mediterranean diet and the DASH (Dietary Approaches to Stop Hypertension) diet, with modifications to include foods that have been putatively associated with a decreased risk of dementia. METHODS We performed a two-site, randomized, controlled trial involving older adults without cognitive impairment but with a family history of dementia, a body-mass index (the weight in kilograms divided by the square of the height in meters) greater than 25, and a suboptimal diet, as determined by means of a 14-item questionnaire, to test the cognitive effects of the MIND diet with mild caloric restriction as compared with a control diet with mild caloric restriction. We assigned the participants in a 1:1 ratio to follow the intervention or the control diet for 3 years. All the participants received counseling regarding adherence to their assigned diet plus support to promote weight loss. The primary end point was the change from baseline in a global cognition score and four cognitive domain scores, all of which were derived from a 12-test battery. The raw scores from each test were converted to z scores, which were averaged across all tests to create the global cognition score and across component tests to create the four domain scores; higher scores indicate better cognitive performance. The secondary outcome was the change from baseline in magnetic resonance imaging (MRI)-derived measures of brain characteristics in a nonrandom sample of participants. RESULTS A total of 1929 persons underwent screening, and 604 were enrolled; 301 were assigned to the MIND-diet group and 303 to the control-diet group. The trial was completed by 93.4% of the participants. From baseline to year 3, improvements in global cognition scores were observed in both groups, with increases of 0.205 standardized units in the MIND-diet group and 0.170 standardized units in the control-diet group (mean difference, 0.035 standardized units; 95% confidence interval, -0.022 to 0.092; P = 0.23). Changes in white-matter hyperintensities, hippocampal volumes, and total gray- and white-matter volumes on MRI were similar in the two groups. CONCLUSIONS Among cognitively unimpaired participants with a family history of dementia, changes in cognition and brain MRI outcomes from baseline to year 3 did not differ significantly between those who followed the MIND diet and those who followed the control diet with mild caloric restriction.

Plain language summary
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.

Bacterial vaginosis (BV) is characterised by the depletion of lactic acid bacteria and overgrowth of certain anaerobic and facultative bacteria leading to an imbalance in the vagina. The high recurrence rate of BV results in repeated exposure to antibiotics and the emergence of drug-resistant bacteria. The aim of this study to evaluate the efficacy of MED-01 [a complex that includes five probiotic strains] on vaginal health and safety This study was a 12-week, randomised, multicentre, double-blind, placebo-controlled clinical trial with two parallel groups receiving either MED-01 or placebo capsules. Results showed that MED-01 intake significantly reduces the Nugent score, a discriminant index of BV, and alleviates symptoms which may appear in BV without any adverse events. Additionally, MED-01 increased the proportion of beneficial Lactobacilli and diminished the harmful BV-causing pathogens. However, there was no significant change in vaginal microbiota. Authors conclude that their findings suggest the possibility of using MED-01 as a new and safe functional probiotic for women with symptoms of BV.
Abstract
Bacterial vaginosis (BV) is the most common disease in women of childbearing age and is caused by the growth of abnormal microbiota in the vagina. Probiotic consumption can be an effective alternative treatment to preserve or improve vaginal health. In the present study, MED-01, a complex of five strains of probiotic candidates isolated from the vagina of Korean women, was used. This study was designed as a 12-week, randomized, multicenter, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of MED-01 on vaginal health. A total of 101 reproductive-aged women with a Nugent score of 4-6 took MED-01 (5.0 × 109 CFU) or a placebo once a day, and 76 participants completed the procedure. MED-01 significantly reduced the Nugent score compared with the placebo. Quantitative PCR analysis confirmed that Lactobacillus plantarum was significantly increased in the vagina, whereas harmful bacteria such as Mobiluncus spp., Gardnerella vaginalis, and Atopobium vaginae were suppressed after 12 weeks of MED-01 ingestion. No adverse events to the test food supplements were observed in the participants. These results confirmed that MED-01 can be used as a probiotic for treating BV, as it improves the vaginal microbiota.

Functional gastrointestinal disorders (FGID) are now termed disorders of gut-brain interaction. Several studies support the consumption of individual foods to improve laxation and gastrointestinal (GI) comfort. The aim of this study was to investigate the effects of the daily consumption of 2 Zespri green kiwifruits compared with those of 7.5 g of psyllium for 4 weeks on parameters of bowel habit and GI comfort. This study was a prospective randomised, single-blinded, crossover, controlled 16-week trial undertaken in 3 countries. The participants were randomised to consume either of the interventions. Results showed that consumption of 2 Zespri green kiwifruits per day is associated with a clinically significant increase in complete spontaneous bowel movements, improvements in abdominal comfort, straining and stool form, and increases in quality of life. Authors concluded that consumption of 2 green kiwifruits can be safely recommended as an effective treatment for constipation in those with functional GI disorders that will also provide improvements in symptoms of GI comfort.
Abstract
INTRODUCTION Consumption of green kiwifruit is known to relieve constipation. Previous studies have also reported improvements in gastrointestinal (GI) comfort. We investigated the effect of consuming green kiwifruit on GI function and comfort. METHODS Participants included healthy controls (n = 63), patients with functional constipation (FC, n = 60), and patients with constipation-predominant irritable bowel syndrome (IBS-C, n = 61) randomly assigned to consume 2 green kiwifruits or psyllium (7.5 g) per day for 4 weeks, followed by a 4-week washout, and then the other treatment for 4 weeks. The primary outcome was the number of complete spontaneous bowel movements (CSBM) per week. Secondary outcomes included GI comfort which was measured using the GI symptom rating scale, a validated instrument. Data (intent-to-treat) were analyzed as difference from baseline using repeated measures analysis of variance suitable for AB/BA crossover design. RESULTS Consumption of green kiwifruit was associated with a clinically relevant increase of ≥ 1.5 CSBM per week (FC; 1.53, P < 0.0001, IBS-C; 1.73, P = 0.0003) and significantly improved measures of GI comfort (GI symptom rating scale total score) in constipated participants (FC, P < 0.0001; IBS-C, P < 0.0001). No significant adverse events were observed. DISCUSSION This study provides original evidence that the consumption of a fresh whole fruit has demonstrated clinically relevant increases in CSBM and improved measures of GI comfort in constipated populations. Green kiwifruits are a suitable dietary treatment for relief of constipation and associated GI comfort.

Frailty and pre-frailty are associated with an increased risk of premature mortality. Factors involved in the development of frailty include physical activity, sleep and nutrition. The aim of this 6-month randomised controlled trial was to evaluate the effects of an educational programme on frailty, physical function, physical activity, sleep and nutritional status. 166 community-dwelling individuals aged 65 years or over with frailty or pre-frailty were randomised to either receive a health education programme consisting of 4 group sessions in the first month which included guidelines for physical activity, nutrition and cognitive training as well as the promotion of psychological and social wellbeing and 6 follow-up calls over 6 months or their usual healthcare (control). Compared to the control group, the intervention group had significant reductions in frailty score, exhaustion and fatigue score, increase in gait speed and improvements in various physical function tests. The intervention group also showed significant improvements in mini nutritional assessment compared to the control group although this was not associated with significant changes in anthropometric parameters. There was a significant increase in awakenings in the control group whilst this parameter did not change in the intervention group, whilst there were no changes in other sleep parameters. The authors concluded that the simplicity, affordability and effectiveness of the health education programme may contribute to healthy ageing.

Introduction
- Frailty and pre-frailty increase the risk of premature mortality but are reversible
- The aim of this study was to evaluate the effects of a health education programme on frailty status in frail or pre-frail older persons.
Methods
- Randomised controlled trial
- Participants: 166 community-dwelling individuals aged 65 years or over with frailty or pre-frailty living in Spain were enrolled, 163 completed the study (80 in intervention and 83 in control group)
- Four weekly group sessions which included guidelines for physical activity, nutrition and cognitive training as well as the promotion of psychological and social wellbeing and 6 follow-up calls over 6 months versus usual healthcare (control).
Results
- Baseline demographics: The educational group consisted of more women (p=0.001), had a younger average age (p=0.019), lower height (p=0.001) and a higher average education level (p=0.013) compared to the control group.
Effects on intervention group:
- Reductions in frailty score (p<0.05 vs baseline and change vs change in control group), with 30% of participants in the intervention group no longer being classified as frail or pre-frail in contrast to none in the control group
- Reductions in fatigue and exhaustion score (p<0.05 vs baseline and change vs change in control group)
- Increase in gait speed and improvements in various physical function tests (all p<0.05 vs baseline and change vs change in control group)
- Improvements in mini nutritional assessment (p<0.001 vs baseline and change vs change in control group)
- Improvement in sleep behaviour demonstrated by an increase in awakenings in the control group (p<0.05 vs baseline and change vs change in intervention group) whilst this parameter did not change in the intervention group.
No effects (vs control) on:
- Anthropometric parameters/unintended weight loss
- Other sleep parameters
- Physical activity expenditure and physical activity score
- Hand grip strength.
Conclusion
This affordable and simple health education programme is effective in reducing frailty in elderly and may contribute to healthy ageing.
Clinical practice applications:
- A comprehensive programme, encompassing not only nutrition, but also exercise, cognitive training and a focus on social and psychological wellbeing may be most effective in improving frailty and physical functioning
- Nutrition intervention, alongside other lifestyle interventions, may have benefits for nutritional status in older adults, even if this is not reflected in a change in anthropometric parameters, such as weight.
Considerations for future research:
- Studies with longer-term follow-up would help evaluate whether/for how long the benefits are sustained.
Abstract
INTRODUCTION The prevalence of frailty is increasing worldwide, emphasizing the importance of prioritizing healthy ageing. To address this, cost-effective and minimally supervised interventions are being sought. This study aimed to assess the impact of an educational program on frailty status, physical function, physical activity, sleep patterns, and nutritional status in community-dwelling older adults with at least 1 Fried's frailty criteria. METHODS A 6-month multicentre randomized controlled trial was conducted from March 2022 to February 2023 in 14 health centres located in Cadiz and Malaga, Spain. The educational intervention consisted of 4 group sessions and 6 follow-up phone calls spread over 6 months. The program focused on educating participants about frailty and its impact on health, providing guidelines for physical activity, healthy dietary habits, cognitive training, psychological well-being and social activities. A total of 163 participants, divided into control (n = 80) and educational groups (n = 83) were assessed before and after the intervention. RESULTS The results showed a significant group-time interaction in the physical function evaluated with a large effect on Short Physical Performance Battery score (η2p = 0.179, -0.1 [-1.2-1.0] points for control group vs. 1.0 [0.0-3.0] points for educational group, p < 0.001), and an effect on the 4-meter gait test ((η2p = 0.122, 0.5 [0.1-0.0] s for control group vs. -0.4 [-0.5- -0.3] s for educational group, p < 0.001), and the 5-repetition sit-to-stand test (η2p = 0.136, 1.0 [0.0-1.2] s for control group vs. -4.3 [-7.0- -2.3] for educational group, p < 0.001). Additionally, the use of accelerometers to assess physical activity, inactivity, and sleep patterns revealed a significant small effect in the number of awakenings at night ((η2p = 0.040, 1.1 [-0.5-3.4] awakenings for control group vs. 0.0 [-2.2-0.0] awakenings for educational group, p = 0.009). The findings also highlighted a significant medium effect regarding malnutrition risk, which was assessed using the Mini-Nutritional Assessment score (η2p = 0.088, -0.7 [-2.3-1.5] points for control group vs. 1.5 [-0.5-3.0] points for educational group, p < 0.001). DISCUSSION Thus, the 6-month educational program effectively improved physical function, sleep patterns, and nutritional status compared to usual healthcare attendance in community-dwelling older adults with frailty or pre-frailty. These findings underscore the potential of minimally supervised interventions in promoting a healthy lifestyle in this vulnerable population.

Unipolar depression is a prevalent and disabling condition that negatively influences quality of life. Patients with depression are more vulnerable to have a poorer health-related quality of life (HRQoL). The aim of this study was to assess the effect of 2-year intervention with Mediterranean Diet enriched with extra virgin olive oil on HRQoL. This study is a multicentre, randomised, controlled, single-blind trial. The study included 52 men and 144 women aged between 18 and 86 years who had suffered at least one depression episode and who were in a stage of clinical remission. The participants were randomly assigned to the intervention or control group. Results show that a Mediterranean diet–based nutritional intervention enriched with extra virgin olive oil compared with usual care, resulted in a significantly greater increase in HRQoL in recovered depressed patients. This association was greater for the mental dimensions rather than the physical dimensions. Furthermore, this association was also observed for participants aged 60 or more. Authors conclude that since depression is an important condition for its high prevalence, economic cost and personal suffering, it is important to evaluate cost-effective, safe, and inexpensive interventions, such as Mediterranean Diet nutritional interventions.
Abstract
INTRODUCTION There is substantial evidence supporting that improving diet quality leads to improved health-related quality of life (HRQoL). Our major aim was to assess the effectiveness of a Mediterranean diet-based nutritional intervention to improve HRQoL in the context of a secondary prevention trial of depression. Secondarily to assess its effectiveness among adults aged 60 or more years. METHODS The PREDIDEP study is a 2-year multicentre, randomized, single-blinded nutritional trial. At baseline and at 1-year and 2-year follow-up, SF-36 health survey questionnaire was collected to evaluate participants' HRQoL (total and specific range for each of the 8 dimensions: 0 to 100 points). Mixed effect linear models were used to assess changes in HRQoL according to adherence to the Mediterranean diet. The trial was registered at ClinicalTrials.govNCT03081065. RESULTS After 2 years of intervention, the Mediterranean Diet intervention group compared to control group (without nutritional intervention, only usual clinical care) showed an improvement in some dimensions of HRQoL such as Mental Health (7.22; 95 % CI = 2.22-12.22) (between-group difference: 6.79; 95 % CI -0.14-13.73, p = 0.055); Vitality (9.51; 95 % CI = 4.00-15.03) (between-group difference: 9.00; 95 % CI 1.75-16.25, p = 0.020); Mental Summary Component (2.83; 95 % CI = 0.55-5.11) (between-group difference: 1.17; 95 % CI = -1.96-4.30, p = 0.462); and General Health (10.70; 95 % CI = 5.58-15.81) (between-group difference: 6.20; 95 % CI = -0.89-13.28, p = 0.086). Similar results were observed for participants aged 60 or more years. CONCLUSION The intervention based on Mediterranean diet in patients with previous depression seems to be effective in improving HRQoL, especially the mental dimensions. This effect is also observed among participants aged 60 or more years.

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.

Plain language summary
Aging populations and the increased prevalence of other cancer risk factors have led to an increased incidence of cancer in women globally. Cancer treatments often leave women with a range of residual physical and psychological side effects. Comprehensive cancer rehabilitation can reduce symptom burden and health service utilisation, whilst generally improving health-related quality of life (HRQOL). The primary aim of this study was to test the efficacy of a multimodal, digitised lifestyle intervention on HRQOL of women treated for cancer. This study is a multi-centre, single-blinded, randomised controlled 12-week trial. Fifty-one women previously treated for breast, blood or gynaecological cancer were randomly assigned to either an intervention or usual care arm. Results indicate improvements in many HRQoL domains and in component summary scores. Particularly notable were the improvements in general health and bodily pain, vitality, mental health, and global physical and mental health summary scores among women in the intervention group. Authors conclude that the complex and synergistic effects of many modifiable health behaviours emphasise the need for bundled health behaviour interventions to optimise women’s health and wellbeing after completion of active cancer treatment.
Abstract
BACKGROUND The residual effects of cancer and its treatment can profoundly affect women's quality of life. This paper presents results from a multisite randomized controlled trial that evaluated the clinical benefits of an e-health enabled health promotion intervention (the Women's Wellness after Cancer Program or WWACP) on the health-related quality of life of women recovering from cancer treatment. METHODS Overall, 351 women previously treated for breast, blood or gynaecological cancers were randomly allocated to the intervention (WWACP) or usual care arms. The WWACP comprised a structured 12-week program that included online coaching and an interactive iBook that targeted physical activity, healthy diet, stress and menopause management, sexual wellbeing, smoking cessation, alcohol intake and sleep hygiene. Data were collected via a self-completed electronic survey at baseline (t0), 12 weeks (post-intervention, t1) and 24 weeks (to assess sustained behaviour change, t2). The primary outcome, health-related quality of life (HRQoL), was measured using the Short Form Health Survey (SF-36). RESULTS Following the 12-week lifestyle program, intervention group participants reported statistically significant improvements in general health, bodily pain, vitality, and global physical and mental health scores. Improvements were also noted in the control group across several HRQoL domains, though the magnitude of change was less. CONCLUSIONS The WWACP was associated with improved HRQoL in women previously treated for blood, breast, and gynaecological cancers. Given how the synergy of different lifestyle factors influence health behaviour, interventions accounting for the reciprocity of multiple health behaviours like the WWACP, have real potential for immediate and sustainable change. TRIAL REGISTRATION The protocol for this randomised controlled trial was submitted to the Australian and New Zealand Clinical Trials Registry on 15/07/2014 and approved on 28/07/2014 ( ACTRN12614000800628 ).
