Due to ageing populations, there is a rapid increase in people living with dementia. A number of modifiable risk factors have been identified, including obesity, excessive alcohol consumption, diabetes mellitus, depression, physical inactivity, smoking and social isolation. The aim of this cluster-randomised controlled trial, including 1030 participants at risk of developing dementia aged 60-77, was to evaluate the effectiveness of a multidomain intervention which included optimisation of nutrition and medication, and physical, social, and cognitive activity for two years compared to standard care. There was no benefit of the intervention for the primary outcome global cognitive performance. The intervention had a positive effect on the secondary outcome health-related quality of life but did not have any significant effect on quality of life, depressive symptoms, social inclusion, activities of daily living and instrumental activities of daily living. The study period coincided with the COVID-19 pandemic. Significantly more participants than controls reported perceived COVID-19-related restrictions with regards to nutrition, whilst there was no such differences between groups for physical, cognitive or social activity. Better adherence to the nutrition and social activity components of the programme were associated with better global cognitive performance, whilst there was no association with physical and cognitive activity.
Abstract
INTRODUCTION We investigated the effectiveness of a multidomain intervention to preserve cognitive function in older adults at risk for dementia in Germany in a cluster-randomized trial. METHODS Individuals with a Cardiovascular Risk Factors, Aging, and Dementia (CAIDE) risk score ≥ 9 aged 60 to 77 years were recruited. After randomization of their general practitioner (GP), patients received a multidomain intervention (including optimization of nutrition and medication, and physical, social, and cognitive activity) or general health advice and GP treatment as usual over 24 months. Primary outcome was global cognitive performance (composite z score, based on domain-specific neuropsychological tests). RESULTS Of 1030 participants at baseline, n = 819 completed the 24-month follow-up assessment. No differences regarding global cognitive performance (average marginal effect = 0.010, 95% confidence interval: -0.113, 0.133) were found between groups at follow-up. Perceived restrictions in intervention conduct by the COVID-19 pandemic did not impact intervention effectiveness. DISCUSSION The intervention did not improve global cognitive performance. HIGHLIGHTS Overall, no intervention effects on global cognitive performance were detected. The multidomain intervention improved health-related quality of life in the total sample. In women, the multidomain intervention reduced depressive symptoms. The intervention was completed during the COVID-19 pandemic.

Diet plays an important role in the development and treatment of sarcopenia, the age-related loss of muscle mass and function. Besides protein intake, the intake of polyunsaturated fatty acids (PUFAs) is also suggested to influence muscle physiology and sarcopenia progression. The aim of this study was to assess the dietary intake of PUFAs and PUFAs status in a sample of well-defined sarcopenic older adults. This study was a secondary, exploratory, cross-sectional analysis of 29 older adults (aged 65 years or older) with sarcopenia. Results showed that omega-3 PUFAs intake was low in older adults with sarcopenia. Moreover, PUFAs intake and status did not correspond well in this population. Authors concluded that intake or status of omega-3 was positively associated with measures of sarcopenia, whereas intake of omega-6 was negatively associated.
Abstract
AIMS: To explore the relationship between dietary polyunsaturated fatty acids (PUFAs) intake, nutritional PUFAs status and sarcopenia outcomes in sarcopenic older adults. METHODS The Exercise and Nutrition for Healthy AgeiNg (ENHANce) is an ongoing 5-armed triple blinded randomized controlled trial, in sarcopenic older adults (> 65y) aiming to assess the effect of combined anabolic interventions (protein, omega-3 supplement and exercise) on physical performance in these adults, compared to single/placebo interventions. Baseline data were used for a secondary, exploratory, cross-sectional analysis. Dietary PUFAs intake was assessed with 4-day food records, status with RBC membrane fatty acids profiles. Spearman's rho(ρ) correlation coefficients were calculated to explore associations of PUFAs intake and status with sarcopenia-defining parameters (muscle strength, mass and physical performance), physical activity (step count) and quality of life (SF-36, SarQoL). RESULTS In total, 29 subjects (9♂/20♀, mean age 76.3 ± 5.4y) were included. Total omega-3 intake of participants (1.99 ± 0.99 g/d) was below the recommended intake (♂:2.8-5.6 g/d; ♀:2.2-4.4 g/d). Intake and status of PUFAs were not correlated. Regarding correlations with outcomes, α-linolenic acid status was inversely associated with appendicular lean mass (aLM) (ρ:-0.439; p = 0.017), whereas docosahexaenoic acid status was positively associated with aLM (ρ:0.388; p = 0.038). Some omega-3 PUFAs intake and status markers were positively associated with step count, SF-36 and SarQoL scores, whereas gamma-linolenic acid status was inversely associated with SF-36 physical component summary score (ρ = -0.426; p = 0.024). CONCLUSIONS Although intake of omega-3 and omega-6 was low, the present exploratory study generated new hypotheses for potential correlations of PUFAs intake and status with sarcopenia outcomes in older adults with sarcopenia.

Plain language summary
Inflammatory bowel disease (IBD), including Crohn disease and ulcerative colitis, are chronic inflammatory diseases of the gastrointestinal tract, characterised by periods of remission and relapse of symptoms. The aim of this study was to assess the effects of a tailored lifestyle intervention on physical fitness (maximal and submaximal exercise capacity, strength, and core stability), the patient-reported outcomes (quality of life, fatigue, and fear), clinical disease activity, and nutritional status. This study was a prospective single-centre randomised semi-crossover-controlled trial. Children were randomized into group A (start exercise) or group B (start control period). Results showed improved physical fitness, quality of life, and parent-reported fatigue. Additionally, a combination of lower clinical disease activity scores accompanied by fewer IBD symptoms suggests positive effects on intestinal inflammation. Authors concluded that based on the findings of their study, children and adolescents with IBD should be motivated and supported to acquire and maintain a healthy lifestyle.

Summary Review:
Introduction
A randomised semi-crossover controlled trial was conducted to investigate the impact of a 12-week lifestyle program (3 physical training sessions per week plus personalised healthy dietary advice) in children with Inflammatory Bowel Disease (IBD).
Method
- Sixteen children with a median age of 15 [IQR: 12–16]) that were diagnosed with IBD (CD, UC, or IBD-unclassified) were randomized to group A (start exercise) or group B (start control period). Group A started the intervention immediately after the first assessment and did not have a control period. Group B started after a control period (this was planned to last for 6 weeks but due to the COVID-19 lockdown extended to 6 months)
- The lifestyle intervention lasted 12 weeks and consisted of 3 physiotherapist-supervised training sessions per week, lasting 60 minutes each. In addition, all participants received a recommended caloric intake per day based on measured rest energy expenditure and a brochure regarding healthy diet in children
- Endpoints were physical fitness (maximal and submaximal exercise capacity, strength, and core stability), patient-reported outcomes (quality of life, fatigue, and fears for exercise), clinical disease activity (faecal calprotectin and disease activity scores), and nutritional status (energy balance and body composition)
- A total of 15 out of 16 participants (93%) completed the program, one patient dropped out after one training session due to motivational problems.
Results
The primary findings of this study were as follows:
- While medical treatment remained unchanged, Paediatric Crohn's Disease Activity Index decreased versus the control period (15 [3–25] vs 2.5 [0–5], P = 0.012)
- The number of patients in clinical remission increased from 5 to 12 (P < 0.001), compared to the control period
- Quality of life (IMPACT-III) improved on 4 out of 6 domains and the total score (+13 points) versus the control period including a large improvement in bowel-related symptoms, P= 0.029)
- Fecal calprotectin decreased, but not compared to the control period, mainly due to relatively large intra-patient fluctuations (400 μg/g [57.1–1662.7] vs 128 μg/g [23.8–642.3], P = 0.016)
- Parents reported an improvement in the quality of life versus the control period on the child health questionnaire and total fatigue score (PedsQoL • Multidimensional Fatigue Scale) (+14 points, P = 0.048)
- Walking distance improved after the 12-week program, compared to the control period (P = 0.001).
Conclusion
This study revealed that a 12-week physical training program and personalised dietary advice improved bowel symptoms, quality of life, and fatigue in children with IBD.
Clinical practice applications:
- The mechanism behind the anti-inflammatory effects of exercise has not been clarified
- Multiple theories have been suggested in previously published studies such as a reduced release of adipokines due to less visceral fat, increased secretion of anti-inflammatory cytokines such as interleukin (IL)-6, and reduced transient stool time
- This clinical trial demonstrated that a 12-week program of physical training sessions plus personalised healthy dietary advice resulted in improved physical fitness, quality of life, and parent-reported fatigue.
Considerations for future research:
- A sample size calculation was not provided in the study report and it is therefore assumed that the sample size of 16 children in this trial was too small to draw a definite conclusion. A larger study over a longer period is therefore needed across diverse age and ethnic population groups to draw better conclusions
- This study did not measure mucosal inflammation before and after the intervention due to the invasive nature of the procedure. It would however be useful that future research investigate this to gain more insight into the effect of lifestyle interventions on IBD.
Abstract
OBJECTIVES Physical activity programs have been suggested as adjunctive therapy in adult inflammatory bowel disease (IBD) patients. We assessed the effects of a 12-week lifestyle intervention in children with IBD. METHODS This study was a randomized semi-crossover controlled trial, investigating a 12-week lifestyle program (3 physical training sessions per week plus personalized healthy dietary advice) in children with IBD. Endpoints were physical fitness (maximal and submaximal exercise capacity, strength, and core stability), patient-reported outcomes (quality of life, fatigue, and fears for exercise), clinical disease activity (fecal calprotectin and disease activity scores), and nutritional status (energy balance and body composition). Change in maximal exercise capacity (peak VO 2 ) was the primary endpoint; all others were secondary endpoints. RESULTS Fifteen patients (median age 15 [IQR: 12-16]) completed the program. At baseline, peak VO 2 was reduced (median 73.3% [58.8-100.9] of predicted). After the 12-week program, compared to the control period, peak VO 2 did not change significantly; exercise capacity measured by 6-minute walking test and core-stability did. While medical treatment remained unchanged, Pediatric Crohn's Disease Activity Index decreased significantly versus the control period (15 [3-25] vs 2.5 [0-5], P = 0.012), and fecal calprotectin also decreased significantly but not versus the control period. Quality of life (IMPACT-III) improved on 4 out of 6 domains and total score (+13 points) versus the control period. Parents-reported quality of life on the child health questionnaire and total fatigue score (PedsQoL Multidimensional Fatigue Scale) also improved significantly versus the control period. CONCLUSIONS A 12-week lifestyle intervention improved bowel symptoms, quality of life, and fatigue in pediatric IBD patients.

Plain language summary
Sarcopenia is a muscle disease, characterised by loss of muscle mass and function, leading to ‘muscle failure’. Primary sarcopenia is age-driven and one of the major mechanisms behind the onset and progression of sarcopenia is the chronic low grade inflammatory state related with ageing, the so-called ‘Inflammageing’. The aim of this study was to explore the levels of inflammatory markers (CRP, albumin, IL-1β, IL-6, IL-8 and TNF-α) in older adults with sarcopenia. This study was an exploratory, secondary, cross-sectional analysis. In total, 40 older adults (15 men and 25 women) with probable, confirmed, or severe sarcopenia were included. Results showed subclinical low levels of inflammatory markers in older adults suffering from sarcopenia, compatible with age-related Inflammageing. Positive associations were found between the examined inflammatory markers and sarcopenia-related traits. Furthermore, gender had a significant influence on the associations between these inflammatory markers and sarcopenia-related traits. Authors concluded that their findings stress the complexity of the inflammageing-sarcopenia interplay and the importance of not only looking at muscle mass or the sarcopenia construct when researching sarcopenia, but also considering other sarcopenia-related traits and gender in future research.
Abstract
AIMS: To explore the relationship between inflammatory markers and sarcopenia-related traits in sarcopenic older adults. METHODS Baseline data of the ongoing Exercise and Nutrition for Healthy AgeiNg (ENHANce) study were used for a secondary, exploratory, cross-sectional analysis. ENHANce is a 5-armed triple blinded randomized controlled trial, in older adults (>65y) with sarcopenia defined according to the revised criteria of the European Working Group of Sarcopenia in Older People (EWGSOP2) aiming to assess the effect of combined anabolic interventions (protein supplement, omega-3 supplement and physical exercise) on physical performance, compared to single/placebo interventions. Inflammatory markers C-reactive protein (hs-CRP), albumin, interleukin-1β (IL-1β), IL-6, IL-8, and tumour necrosis factor-α (TNF-α) were assessed at baseline. Spearman's rho (ρ) correlation coefficients were calculated to associate these inflammatory markers with baseline sarcopenia-defining parameters (handgrip strength, chair stand test, appendicular lean mass [aLM], gait speed, Short Physical Performance Battery), physical activity (step count) and quality of life (SF-36, SarQoL). RESULTS We included 40 sarcopenic subjects (15 men/25 women, age 77.1 ± 6.8 years). Contrary to expectations, the pro-inflammatory IL-1β correlated positively with handgrip strength (ρ: 0.376; p = 0.024) and IL-6 with aLM (ρ: 0.334; p = 0.0433). IL-6 inversely correlated with step count (ρ:-0.358; p = 0.048). Subgroup analysis revealed important gender differences. IL-8 inversely correlated with handgrip strength in women (ρ: -0.425; p = 0.034) but not in men. In contrast, pro-inflammatory cytokines CRP (ρ: -0.615; p = 0.019), IL-6 (ρ: -0.604; p = 0.029) and TNF-α (ρ: -0.615; p = 0.025) inversely correlated with the SF-36 physical component score in men but not in women. CONCLUSION Although Inflammageing might play a role in sarcopenia-related traits, this exploratory study highlights an important role of gender. Future research should take this into account when elucidating the Inflammageing-sarcopenia interplay.

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
Osteoporosis, a progressive systematic skeletal disease is caused by diminished bone density and strength, which may increase the risk of fragility fractures in the spine, pelvis, femur etc. Women are at greater risk of developing osteoporosis. Osteopenia is an intermediary stage of reduced bone mineral density before progressing into the osteoporosis disease state. Exercise and pharmacological therapies are considered two effective strategies commonly used in the treatment of osteoporosis. Exercise may help to improve bone mineral density, strength and muscle mass and reduce the risk of fractures. This systematic review and meta-analysis of five parallel-arm randomised controlled trials investigated the combined effect of exercise and pharmacological therapy on bone mineral density, bone turnover markers, fractures and fracture healing in patients with osteopenia and osteoporosis. This systematic review and meta-analysis showed a non-significant improvement in bone mineral density in patients with osteopenia and osteoporosis followed by combined pharmacological treatment with exercise. Pharmacological therapy alone showed improvement and maintenance of bone mineral density. There was no evidence for the improvement in fragility fracture healing. Due to the low evidence and high heterogeneity of included studies, further robust studies are required to evaluate the combined effect of exercise and pharmacological therapy in people with systematic skeletal disease. Healthcare professionals can use this study to understand the benefits of pharmacological therapy in improving osteoporosis and osteopenia and the potential of adding exercise as a therapeutic strategy in clinical practice.
Abstract
This prospectively registered systematic review and meta-analysis examines whether exercise (EX) training has an additive effect to osteoanabolic and/or antiresorptive pharmacological therapy (PT) in people with osteoporosis on bone mineral density (BMD), bone turnover markers (BTMs), fracture healing, and fractures. Four databases (inception to 6 May 2022), 5 trial registries, and reference lists were searched. Included were randomized controlled trials comparing the effect of EX + PT vs. PT with regard to BMD, BTM, fracture healing, and fractures. Risk of bias was assessed using the Cochrane RoB2 and certainty of evidence by the GRADE approach. Random-effects meta-analysis with Hartung-Knapp-Sidik-Jonkman adjustment was used to estimate standardized mean differences and 95% confidence intervals. Out of 2593 records, five RCTs with 530 participants were included. Meta-analysis showed with very low certainty evidence and wide confidence intervals that EX + PT compared to PT had larger effect sizes for BMD at 12 months at the hip (SMD [95%CI]: 0.18 [- 1.71; 2.06], n = 3 studies), tibia (0.25 [- 4.85; 5.34], n = 2), lumbar spine (0.20 [- 1.15; 1.55], n = 4), and forearm (0.05 [- 0.35; 0.46], n = 3), but not femoral neck (- 0.03 [- 1.80; 1.75], n = 3). Furthermore, no improvement was revealed for BTM such as bone ALP (- 0.68 [- 5.88; 4.53], n = 3), PINP (- 0.74 [- 10.42; 8.93], n = 2), and CTX-I (- 0.69 [- 9.61; 8.23], n = 2), but with very wide confidence intervals. Three potentially relevant ongoing trials were identified via registries. No data were found for fracture healing or fracture outcomes. It remains unclear whether EX has an additive impact to PT in people with osteoporosis. High-quality, adequately powered, targetted RCTs are required. PROTOCOL REGISTRATION PROSPERO CRD42022336132.

Gestational Diabetes Mellitus (GDM) causes hyperglycaemia due to the deficit of insulin during pregnancy. Dietary and lifestyle management plays a vital role in maintaining glycaemic control in women with GDM to avoid health risks to the mother and baby. Therefore, this systematic review of fourteen randomised controlled trials evaluated the latest research advancements to identify effective nutritional strategies for managing hyperglycaemia in women with GDM. Among all the dietary strategies implemented in the included randomised controlled trials, probiotic supplementation and supplementation of probiotics and vitamin D were most effective in GDM. Further robust studies are required to evaluate the potential effectiveness of different nutritional strategies for managing GDM. Healthcare professionals can use the results of this systematic review to understand the latest evidence supporting nutritional strategy for women with GDM and the need for personalised support for managing hyperglycaemia in GDM.
Abstract
Gestational diabetes mellitus (GDM) is defined as hyperglycaemia first detected at any time during pregnancy with values lower than those determined by the WHO for diabetes diagnosis in adults. This pathology, with a worldwide prevalence of 13.4%, causes significant maternal and foetal risks. The first line of treatment consists of maintaining normo-glycaemia through an adequate diet and lifestyle changes. The aim is to synthesize the scientific evidence updating the nutritional recommendations for the effective management of GDM. A systematic review of the scientific literature was conducted following the PRISMA guidelines. Randomized clinical trials published within the last five years and providing information on nutritional recommendations to achieve an effective management of gestational diabetes were selected. The databases searched were PubMed, the WOS Core Collection, SCOPUS, and CINAHL, using the MeSH terms: "Diabetes, Gestational"; "Nutrition Assessment (nutrition*)"; "Diet"; "Eating"; and "Food"; with the Boolean operators "AND" and "OR". The PEDro scale (Physiotherapy Evidence Database) was used to assess the scientific quality of the studies, with a mean score of 8.9, indicating an average good scientific quality. Results: A total of 809 papers were collected, of which, after applying the inclusion and exclusion criteria, 14 randomized clinical trials were selected. Probiotic supplementation and co-supplementation with vitamin D have been found to be the most beneficial options for both mothers with GDM and neonates, but the most effective regimens are not known. Diets enriched with extra virgin olive oil (EVOO) and oat bran, as well as some recommendations focused on carbohydrates also seem effective, as well as diets designed for this group of women with GDM such as "CHOICE". Conclusions: Although there are numerous proposals that have been published in recent years focused on the diet of women with GDM in order to improve their results and those of their children, it is the supplementation with probiotics and the co-supplementation with vitamin D that is most agreed upon as beneficial; however, more research is needed into which protocols are most effective. Other proposals that could also be beneficial should be further studied.

Several systematic reviews and meta-analyses conducted to evaluate the prognosis of coronavirus disease-2019 (COVID-19) in people with diabetes mellitus have reported an approximately two- to three-fold higher risk of mortality from COVID-19 in people with diabetes mellitus compared with those without diabetes mellitus. The aim of this study was to investigate the impact of the COVID-19 pandemic and the state of emergency on the glycaemic control, eating habits, and body composition of people with diabetes mellitus. This study is a retrospective, longitudinal observational study in outpatients with diabetes mellitus. A total of 408 participants were included in this study, including 239 men (58.6%) and 169 women (41.4%). People with type 2 diabetes mellitus were predominant in this study (96.8%). Results show that: - there was a significant increase of the haemoglobin A1c level in people with diabetes mellitus during the COVID-19 pandemic. - there was an increase in the changes in body weight and percent fat (increased) and skeletal muscle masses (decreased). Authors conclude that the COVID-19 pandemic caused a negative impact on the glycaemic control and body composition in people with diabetes mellitus. Furthermore, the increase of body weight and fat mass and the decrease of the skeletal muscle mass during the pandemic were associated with poor glycaemic control, independent of the age and sex, in people with diabetes mellitus.
Abstract
AIMS/INTRODUCTION To evaluate the impact of the COVID-19 pandemic on the glycemic control, eating habits, and body composition of people with diabetes mellitus; to identify the determinants of worsening glycemic control in people with diabetes mellitus. MATERIALS AND METHODS This retrospective, longitudinal observational study was performed in outpatients with diabetes mellitus who visited our hospital between April 2019 and March 2020 (pre-COVID-19 period) and continued for follow up from April 2020 to March 2021 (COVID-19 period). We compared the glycemic control, nutritional intakes, and body composition of people with diabetes mellitus between the two periods. The changes in the HbA1c values (ΔHbA1c) and other study variables were compared between the two periods. Logistic regression analysis was performed to identify the factors associated with the increase of HbA1c levels. RESULTS A significant increase of HbA1c was observed during the COVID-19 period. The percent fat mass (FM) also increased, while the percent skeletal muscle mass (SMM) decreased during the COVID-19 period. After adjustments for age and sex, the ΔBMI (OR:2.33), ΔFM (OR:1.45), and ΔSMM (OR:0.51) were identified as being associated with elevated levels of HbA1c. CONCLUSIONS The COVID-19 pandemic had a negative impact on the glycemic control and body composition of people with diabetes mellitus. The increased body weight and FM and decreased SMM observed during the pandemic were associated with poor glycemic control in people with diabetes mellitus.

Postmenopausal vasomotor symptoms cause recurrent discomfort, disrupt sleep, and reduce quality of life. A role for nutritional factors in vasomotor symptoms was suggested by their low prevalence in areas where traditional dietary staples included grains, legumes, vegetables, and other plant-derived foods. The aim of this study was to investigate the effects of a dietary intervention on vasomotor symptoms and menopause-related quality of life. This study is a randomised controlled study. Eighty-four participants were randomly assigned, in two cohorts; the intervention or control group. Results show that the dietary intervention led to clinically important reductions in menopausal symptoms. In fact, there was an 88% reduction in moderate-to-severe vasomotor events among participants in the intervention-group, accompanied by weight loss and improvements in physical, psychosocial, and sexual domains. Authors conclude that a dietary intervention, combining a reduced-fat vegan diet and daily soybeans, was associated with a marked reduction in postmenopausal vasomotor events, significant weight loss, and reductions in physical and sexual symptoms.
Abstract
OBJECTIVE Postmenopausal vasomotor symptoms disrupt quality of life. This study tested the effects of a dietary intervention on vasomotor symptoms and menopause-related quality of life. METHODS Postmenopausal women (n = 84) reporting at least two moderate-to-severe hot flashes daily were randomly assigned, in two successive cohorts, to an intervention including a low-fat, vegan diet and cooked soybeans (½ cup [86 g] daily) or to a control group making no dietary changes. During a 12-week period, a mobile application was used to record hot flashes (frequency and severity), and vasomotor, psychosocial, physical, and sexual symptoms were assessed with the Menopause-Specific Quality of Life questionnaire. Between-group differences were assessed for continuous ( t tests) and binary ( χ2 /McNemar tests) outcomes. In a study subsample, urinary equol was measured after the consumption of ½ cup (86 g) of cooked whole soybeans twice daily for 3 days. RESULTS In the intervention group, moderate-to-severe hot flashes decreased by 88% ( P < 0.001) compared with 34% for the control group ( P < 0.001; between-group P < 0.001). At 12 weeks, 50% of completers in the intervention group reported no moderate-to-severe hot flashes at all. Among controls, there was no change in this variable from baseline ( χ2 test, P < 0.001). Neither seasonality nor equol production status was associated with the degree of improvement. The intervention group reported greater reductions in the Menopause-Specific Quality of Life questionnaire vasomotor ( P = 0.004), physical ( P = 0.01), and sexual ( P = 0.03) domains. CONCLUSIONS A dietary intervention consisting of a plant-based diet, minimizing oils, and daily soybeans significantly reduced the frequency and severity of postmenopausal hot flashes and associated symptoms.

Plain language summary
Non-alcoholic fatty liver disease (NAFLD) is defined as the presence of 5% or more fat in the liver, confirmed by hepatic imaging or biopsy. Poor sleep may adversely affect insulin sensitivity and inflammatory status, thereby contributing to the development and progression of NAFLD. The aim of this study was to investigate how intermittent fasting combined with exercise impacts body weight and sleep measures in adults with NAFLD. This study was a secondary analysis of a 3-month randomised, controlled, parallel-arm study. Participants were randomized to 1 of 4 intervention groups: alternate-day fasting (ADF) plus exercise, ADF alone, exercise alone, or a no-intervention control group. Results showed that intermittent fasting combined with exercise produced significant reductions in body weight and intrahepatic triglyceride content but no changes in sleep quality, duration, insomnia severity, or risk of obstructive sleep apnoea. Authors conclude that the weight loss induced by ADF combined with exercise does not improve sleep quality, duration, insomnia severity or risk of obstructive sleep apnea in individuals with obesity and NAFLD.
Abstract
Objective: This study investigated how alternate-day fasting (ADF) combined with aerobic exercise impacts body weight and sleep in adults with non-alcoholic fatty liver disease (NAFLD). Methods: Adults with obesity and NAFLD (n = 80) were randomized into one of four groups for 3 months: combination of ADF (600 kcal "fast day," alternated with an ad libitum intake "feast day") and moderate-intensity aerobic exercise (five sessions per week, 60 min/session); ADF alone; exercise alone; or a no-intervention control group. Results: By month 3, body weight and intrahepatic triglyceride content decreased (p < 0.001, group × time interaction) in the combination group versus the exercise group and control group, but not versus the ADF group. Sleep quality, measured by the Pittsburgh Sleep Quality Inventory (PSQI), did not change in the combination group (baseline: 6.0 ± 0.7; month 3: 5.6 ± 0.7), ADF group (baseline: 8.9 ± 1.0; month 3: 7.5 ± 0.8), or exercise group (baseline: 6.4 ± 0.6; month 3: 6.7 ± 0.6), versus controls (baseline: 5.5 ± 0.7; month 3: 4.6 ± 0.5). Wake time, bedtime, sleep duration, and insomnia severity did not change (no group x time interaction) over the course of the study in any group. Risk for obstructive sleep apnea was present in 30% of combination subjects, 75% of ADF subjects, 40% of exercise subjects, and 75% of controls, and did not change in the intervention groups, versus controls, by month 3. No associations were observed between changes in body weight, intrahepatic triglyceride content, and any sleep outcome. Conclusions: The weight loss induced by ADF combined with exercise does not improve sleep quality, duration, insomnia severity, or risk of obstructive sleep apnea in individuals with NAFLD.
