COVID-19 pandemic raised concerns about the effects of stress on mental health and sleep deficiency. Cognitive behavioural therapy for insomnia (CBT-I) has been shown to improve sleep quality and insomnia severity, as well as anxiety and depression, and may be protective during times of stress, including the COVID-19 pandemic. The aim of this study was to examine changes in sleep, sleep-related cognitions, stress, anxiety, and depression among people with heart failure (HF). This study was a randomised controlled trial of the effects of CBT-I compared with HF self-management education (attention-control condition), the “HeartSleep Study.” Results showed that improvements in insomnia severity, sleep quality, latency, and efficiency, sleep-related cognitions and stress, anxiety, and depression after participation in CBT-I or an HF self-management class were sustained during the pandemic. Authors conclude that their findings confirm the clinical benefits of CBT-I for people with HF and comorbidities and also suggest the potential benefits of HF self-management education.
Abstract
BACKGROUND The COVID-19 pandemic raised concerns about the effects of stress on sleep and mental health, particularly among people with chronic conditions, including people with heart failure (HF). OBJECTIVE The aim of this study was to examine changes in sleep, sleep-related cognitions, stress, anxiety, and depression among people with HF who participated in a randomized controlled trial of cognitive behavioral therapy for insomnia before the COVID-19 pandemic. METHODS Participants self-reported sleep characteristics, symptoms, mood, and stress at baseline, 6 months after cognitive behavioral therapy for insomnia or HF self-management education (attention control), and during the pandemic. RESULTS The sample included 112 participants (mean age, 63 ± 12.9 years; 47% women; 13% Black; 68% New York Heart Association class II or III). Statistically significant improvements in sleep, stress, mood, and symptoms that occurred 6 months post treatment were sustained during the pandemic. CONCLUSIONS Improving sleep and symptoms among people with HF may improve coping during stressful events, and cognitive behavioral therapy for insomnia may be protective.

Platinum-based doublet chemotherapy occupies an important role in the management of lung cancer; however, there are treatment-associated side effects. These symptoms may deteriorate the quality of life for patients undergoing chemotherapy, and even necessitate dose reduction or discontinuation. The aim of this study was to determine whether oral compound probiotic supplements can reduce chemotherapy-related adverse effects and improve lung cancer patients' quality of life during chemotherapy. This study was a prospective, randomised, placebo-controlled, multicentre clinical study. A total of 100 lung cancer patients undergoing chemotherapy where enrolled for the study. They were randomly assigned to one of the two groups: intervention (probiotics) vs placebo. Results showed that the participants receiving probiotic supplements were significantly better in various dimensions of the overall quality of life, role function, nausea and vomiting, appetite loss, constipation, and diarrhoea relative to the placebo group. Authors concluded that compound probiotic supplements can improve the quality of life and relieve platinum-based doublet chemotherapy-induced gastrointestinal adverse reactions for lung cancer patients undergoing chemotherapy.
Abstract
BACKGROUND Chemotherapy is an important approach for lung cancer patients. The study was designed to evaluate the feasibility of the compound probiotic supplements in improving the quality of life for lung cancer patients undergoing chemotherapy. METHODS This randomized, double-blind, placebo-controlled trial enrolled chemotherapy-naive patients with lung cancer who were scheduled to receive platinum-based doublet chemotherapy. All eligible patients were randomly administered (1:1) compound probiotic supplements (group BP-1) or placebo (group C) for two chemotherapy cycles. The EORTC QLQ C30 questionnaire scores were evaluated before the first, second, and third cycles of chemotherapy. The primary endpoint was the difference in the EROTC QLQ C30 questionnaire score between the two groups after two cycles of chemotherapy. RESULTS A total of 110 patients were recruited from March 2021 to January 2022. After undergoing two cycles of chemotherapy, group BP-1 were significantly better in various dimensions of the overall quality of life, role function, nausea and vomiting, appetite loss, constipation, and diarrhea relative to group C (76.90 ± 18.31 vs. 58.89 ± 17.17; 93.33 ± 11.58 vs. 85.93 ± 15.06; 0.00 ± 0.00 vs. 27.04 ± 29.15; 6.67 ± 13.53 vs. 22.22 ± 18.80; 0.95 ± 5.63 vs. 28.15 ± 22.42; 2.86 ± 9.47 vs. 15.56 ± 16.82; p < 0.05, respectively). The incidence of nausea and vomiting, appetite loss, constipation, and diarrhea in group BP-1 was significantly lower than in group C (0% vs. 71.43%, 16.67% vs. 57.14%, 2.38% vs. 63.27%, and 7.14% vs. 42.86%, respectively, p < 0.001). CONCLUSIONS Compound probiotic supplements can improve the quality of life and relieve chemotherapy-related gastrointestinal side effects for lung cancer patients receiving platinum-based doublet chemotherapy.

Relaxation techniques, diet, and exercise can diminish atopic dermatitis (AD) symptoms. Patients with AD worry about the side-effects of the medical treatment for AD thus the majority try to engage in potentially healthy lifestyle behaviours. The aim of this study was to exploratively investigate the effectiveness of hypnotherapy, fasting with diet adjustments, and exercise in adult AD patients This study is a four-armed, randomised controlled, single-centre, open explorative clinical trial. Patients were randomly assigned to one of the four groups: i) hypnotherapy group program (HTP), ii) intermittent fasting with diet adjustment group program (IFDP), iii) an exercise group program or the control group. The study was strongly impacted by confinements and research restrictions due to the coronavirus 2019 pandemic. However, results showed potential beneficial changes to baseline in perceived itching intensity, disease severity, and disease-specific quality of life for HTP and IFDP. Authors conclude that further high-quality clinical trials should be performed investigating the effectiveness and safety of hypnotherapy, fasting with diet adjustments, as well as exercise.
Abstract
Background: Patients with atopic dermatitis (AD) frequently use healthy lifestyle behaviors, although their benefits are unclear. This study's aim was to investigate the effectiveness of hypnotherapy, fasting with diet adjustments, and exercise in AD patients. Methods: In a four-armed randomized controlled monocenter open explorative clinical trial, adult patients with mild-to-moderate severe AD underwent, over 16 weeks, a five-session hypnotherapy group program (HTP), a five-session intermittent fasting with diet adjustment group program (IFDP), a five-session exercise group program (EP), or no study intervention (control) as add-on to topical corticosteroid use if required. Endpoints included subjectively perceived itching on a visual analogue scale (VAS, 0-100 mm); disease severity by SCORing Atopic Dermatitis (SCORAD); and adverse events (AEs). Endpoints were analyzed descriptively in the Full Analysis Set (FAS). Due to the coronavirus disease 2019 (COVID-19) pandemic, relevant changes to the study protocol included online in addition to "in-presence" group interventions, closing the study arm EP and premature trial termination before randomization of 120 intended patients. Results: During the COVID-19 pandemic, study recruitment was poor. The FAS included 20 patients (17 female) with 35.0 ± 12.1 (mean ± standard deviation [SD]) years of age. At baseline, mean ± SD for HTP (n = 6), IFDP (n = 4), EP (n = 1), and control (n = 9) were VAS itching 63.2 ± 18.0, 65.0 ± 13.9, 43.0 mm, 62.1 ± 17.3; SCORAD 43.0 ± 13.6, 47.0 ± 21.0, 60.3, 39.1 ± 15.6. After 16 weeks, endpoints were VAS itching 26.0 ± 16.4, 31.7 ± 9.9, 23.0 mm, 39.3 ± 27.0; SCORAD 24.1 ± 12.2, 29.1 ± 19.1, 49.1, 25.5 ± 14.4. No serious AEs related to the interventions were observed. Conclusion: Despite very small groups, study results indicated potential beneficial changes to baseline in perceived itching intensity, disease severity, and disease-specific quality of life for HTP and IFDP. Therefore, further clinical trials should be performed investigating the effectiveness and safety of all interventions.

Plain language summary
Hypertension is one of the primary causes of cardiovascular disease, stroke, Alzheimer’s Disease, and Alzheimer’s Disease and related dementias (AD/ADRD). Among individuals with hypertension, those with resistant hypertension (RH) appear to have the greatest risk of cerebrovascular disease and associated cognitive impairment. The aim of this study was to investigate the potential influence of individual differences in pre-treatment inflammatory profiles on changes in cognition following lifestyle modification among RH participants in the TRIUMPH clinical trial. This study is a report based on the TRIUMPH study which was a randomised clinical trial. One hundred forty patients with RH were randomised with 2:1 allocation to either a 4-month Centre-based Lifestyle intervention or Standardized Education and Physician Advice. Results show that basal levels of elevated peripheral inflammation may represent an intermediate phenotype of risk for cognitive decline. In fact, individuals with higher levels of c-reactive protein at baseline demonstrated greater improvements in Executive Function/Learning following participation in an intensive lifestyle intervention. Authors conclude that their findings may help inform targeted treatments to reduce ADRD among middle-aged and older adults with cardiovascular disease risk factors.
Abstract
Individuals with resistant hypertension (RH) have the greatest risk of cerebrovascular disease and cognitive impairment among individuals with hypertension. Elevated levels of pro-inflammatory cytokines may represent a critical yet unexamined factor influencing the impact of healthy lifestyle changes on cognitive function. We explored the influence of inflammation on changes in cognition following lifestyle modification among individuals with RH participating in the TRIUMPH clinical trial. One hundred forty participants with RH completed a battery of neurocognitive tests along with the inflammatory marker C-reactive protein (hsCRP) and were subsequently randomized to an intensive 4-month lifestyle modification intervention or to education and physician advice control. Results indicated that the effects of lifestyle modification on Executive Function and Learning were moderated by pre-intervention hsCRP levels (P = .049), with treatment efficacy increasing across levels of baseline inflammation levels (low: d = 0.12; mild: d = 0.43; moderate: d = 0.81). We conclude that inflammatory profiles may help identify individuals more likely to improve executive functioning resulting from lifestyle modification.

Breast cancer (BCa) is the most common form of cancer among women. Radiotherapy (RT) treatment is an important component of breast cancer treatment and is used with curative intent as well as for palliation. One commonly reported adverse side effect of RT is cancer related fatigue (CRF). The aims of this study were to (a) examine the effects of a 12-week home-based resistance and aerobic exercise program on CRF, health-related quality of life (HRQoL), and sleep quality and duration in BCa patients during and up to 12 months after RT, and (b) investigate how CRF, HRQoL, and sleep quality and duration affect the participants’ ability to follow their prescribed exercise program. This study was a two-arm, randomised controlled clinical trial. One hundred and six (n = 106) women with stage I-III BCa scheduled to receive radical RT were randomised into exercise (n = 51) or usual care (n = 55). Results show that CRF was present at baseline and persisted during RT. The exercise group had a quicker reduction in CRF compared to the usual care group. Moreover, there was a significant difference in the HRQoL during RT between groups, and a quicker HRQoL improvement post-RT for the exercise group, with no changes in sleep quality or duration. Additionally, less fatigue and less trouble sleeping were associated with greater weekly aerobic exercise duration and higher rating of perceived exertion during aerobic exercise. Authors conclude that home-based exercise during RT is safe and effective in reducing CRF and improving HRQoL
Abstract
BACKGROUND Radiotherapy (RT) can lead to cancer-related fatigue (CRF) and decreased health-related quality of life (HRQoL) in breast cancer patients. The purpose of this trial was to examine the feasibility and efficacy of a home-based resistance and aerobic exercise intervention for reducing CRF and improving HRQoL in breast cancer patients during RT. METHODS Women with breast cancer (N = 106) commencing RT were randomized to 12 weeks of home-based resistance and aerobic exercise (EX) or usual care/control (CON). The primary endpoint was CRF, with secondary endpoints of HRQoL, sleep duration and quality, and physical activity. Measurements were undertaken prior to RT, at completion of RT (~ 6 weeks), at completion of the intervention (12 weeks), and 6 and 12 months after RT completion, while CRF was also measured weekly during RT. RESULTS Eighty-nine women completed the study (EX = 43, CON = 46). Over the 12-week intervention, EX completed 1-2 resistance training sessions and accumulated 30-40 min of aerobic exercise weekly. For CRF, EX had a quicker recovery both during and post-RT compared to CON (p < 0.05). Moreover, there was a significant difference in HRQoL between groups at RT completion, with HRQoL unchanged in CON and higher in EX (p < 0.05). There was no change in sleep duration or quality for either group and there were no exercise-related adverse effects. CONCLUSIONS Home-based resistance and aerobic exercise during RT is safe, feasible, and effective in accelerating CRF recovery and improving HRQoL. Improvements in CRF and HRQoL for these patients can be achieved with smaller exercise dosages than stated in the generic recommendations for breast cancer.

Plain language summary
Chronic heart failure (CHF) is the terminal stage of heart disease and in recent years, the prevalence of CHF has been increasing among the elderly. Studies have demonstrated that the incidence rate of malnutrition among elderly patients with stable CHF is relatively high. Thus, how to help elderly CHF patients based at home to effectively carry out nutritional self-management and prevent the occurrence of malnutrition, has become a major focus of medical research. The aim of this study was to test the effect of home-based nutritional intervention method on improving the nutritional status of elderly patients with CHF. This study is a randomised controlled trial that enrolled a total of 90 elderly patients with stable CHF. The patients were randomly divided into the experimental group and the control group. Results show that home-based food exchange nutritional interventions can effectively improve the malnutrition status as well as the cardiopulmonary function and exercise tolerance of elderly patients with CHF. Furthermore, after two months of intervention, the protein content and skeletal muscle mass were significantly higher in the experimental group than in the control group, while the reduction in body fat and body fat rate was also significantly higher in the former than in the latter. Authors conclude that the food exchange method is easy to grasp, operate and master, and is highly suitable for home-based elderly CHF patients.
Abstract
BACKGROUND The home treatment of elderly patients with chronic heart failure (CHF) is often accompanied by malnutrition, which increases the risk of re-hospitalisation and affects the prognosis. Therefore, how to effectively improve the nutritional self-management of patients is a current focus of medical research. This study aims to test the effect of home-based nutritional intervention method on improving the nutritional status of elderly patients with CHF. METHODS A total of 90 hospitalised elderly patients with CHF were randomly divided into the experimental group (n = 45) and the control group (n = 45). The patients in both groups were given standardised drug therapy and their nutritional status was evaluated using a body composition analyser prior to discharge (protein, body fat percentage, visceral fat area, skeletal muscle, upper arm muscle circumference, left lower limb and right lower limb muscle mass), with the cardiopulmonary function evaluated using a six-minute walk test and the metabolic equivalents method. The control group was given general nutrition education and routine dietary guidance from cardiac rehabilitation nurses, while the experimental group was given an individualised nutrition prescription by dietitians based on the evaluation results, according to which one-to-one food exchange dietary intervention training was given until the patients mastered the process. RESULTS The nutritional indexes at the end of the study were significantly higher in the experimental group than in the control group and were higher than those before the intervention (P < 0.05). The muscle circumference of the upper arm, the muscle mass of the left lower limb and the right lower limb had no statistical significance following the intervention compared to the control group and before the intervention (P > 0.05). The cardiopulmonary function indexes were significantly better in the experimental group at the end of the study than before the intervention and were better than those in the control group, with statistically significant differences (P < 0.05), while no significant changes were observed in the control group before and after the intervention (P > 0.05). CONCLUSION The home-based nutritional intervention method of food exchange portions can effectively improve the nutritional status of elderly patients with CHF, with the distribution of visceral fat more reasonable and the cardiopulmonary function and exercise endurance improved.

Plain language summary
Non-alcoholic fatty liver disease (NAFLD) is caused by a build up of fat in the liver. NAFLD is becoming more common, with the rise in rates of obesity. There are no specific medications available for NAFLD and patients are advised to manage their diets and lifestyle following diagnosis. The aim of this study was to assess and evaluate the causal relationship between sleep and NAFLD. The study was a two-way Mendelian randomised clinical trial. Results showed that different sleep traits can be the cause of the onset and exacerbation of NAFLD. NAFLD does not change sleep traits and the causal relationship between them is unidirectional. Authors conclude that sleep characteristics are associated with an elevated risk of NAFLD. Thus, enhancing sleep should be considered by healthcare practitioners as part of prevention and management NAFLD.
Abstract
BACKGROUND AND AIMS Non-alcoholic fatty liver disease(NAFLD) is common worldwide and has previously been reported to be associated with sleep traits. However, it is not clear whether NAFLD changes sleep traits or whether the changes in sleep traits lead to the onset of NAFLD. The purpose of this study was to investigate the causal relationship between NAFLD and changes in sleep traits using Mendelian randomization. METHODS We proposed a bidirectional Mendelian randomization (MR) analysis and performed validation analyses to dissect the association between NAFLD and sleep traits. Genetic instruments were used as proxies for NAFLD and sleep. Data of genome-wide association study(GWAS) were obtained from the center for neurogenomics and cognitive research database, Open GWAS database and GWAS catalog. Three MR methods were performed, including inverse variance weighted method(IVW), MR-Egger, weighted median. RESULTS In total,7 traits associated with sleep and 4 traits associated with NAFLD are used in this study. A total of six results showed significant differences. Insomnia was associated with NAFLD (OR(95% CI)= 2.25(1.18,4.27), P = 0.01), Alanine transaminase levels (OR(95% CI)= 2.79(1.70, 4.56), P =4.71×10-5) and percent liver fat(OR(95% CI)= 1.31(1.03,1.69), P = 0.03). Snoring was associated with percent liver fat (1.15(1.05,1.26), P =2×10-3), alanine transaminase levels (OR(95% CI)= 1.27(1.08,1.50), P =0.04).And dozing was associated with percent liver fat(1.14(1.02,1.26), P =0.02).For the remaining 50 outcomes, no significant or definitive association was yielded in MR analysis. CONCLUSION Genetic evidence suggests putative causal relationships between NAFLD and a set of sleep traits, indicating that sleep traits deserves high priority in clinical practice. Not only the confirmed sleep apnea syndrome, but also the sleep duration and sleep state (such as insomnia) deserve clinical attention. Our study proves that the causal relationship between sleep characteristics and NAFLD is the cause of the change of sleep characteristics, while the onset of non-NAFLD is the cause of the change of sleep characteristics, and the causal relationship is one-way.

Bacterial vaginosis (BV) is a microecological disorder caused by decreased abundance of lactobacilli and an increased abundance of anaerobic bacteria, commonly affecting the female lower genital tract. The aim of this study was to evaluate the effectiveness of oral Chinese-origin probiotic strains (L. gasseri TM13 and L. crispatus LG55), with adjuvant primary treatment in treating Chinese BV patients, and investigate the dynamic of the intestine and vaginal microbiome using metagenomic sequencing. This study was a single-centre, prospective, parallel-group, randomized controlled clinical trial. Participants were randomly assigned to the control or probiotic group using a 1:1 ratio. Results showed that there was no significant difference in BV cure rates between the probiotic and control groups at day 14, day 30, and day 90. In addition, in the BV conversion population, the percentage of people in a transition state was lower in the probiotic group at all three time-points. Hence, oral administration of L. gasseri TM13 and L. crispatus LG55 is effective in restoring the vaginal health of patients recovered from BV. Authors conclude that an individualised intervention approach should be developed to restore the vaginal health of patients recovering from BV.
Abstract
UNLABELLED Bacterial vaginosis (BV) is a common infection of the lower genital tract with a vaginal microbiome dysbiosis caused by decreasing of lactobacilli. Previous studies suggested that supplementation with live Lactobacillus may benefit the recovery of BV, however, the outcomes vary in people from different regions. Herein, we aim to evaluate the effectiveness of oral Chinese-origin Lactobacillus with adjuvant metronidazole (MET) on treating Chinese BV patients. In total, 67 Chinese women with BV were enrolled in this parallel controlled trial and randomly assigned to two study groups: a control group treated with MET vaginal suppositories for 7 days and a probiotic group treated with oral Lactobacillus gasseri TM13 and Lactobacillus crispatus LG55 as an adjuvant to MET for 30 days. By comparing the participants with Nugent Scores ≥ 7 and < 7 on days 14, 30, and 90, we found that oral administration of probiotics did not improve BV cure rates (72.73% and 84.00% at day 14, 57.14% and 60.00% at day 30, 32.14% and 48.39% at day 90 for probiotic and control group respectively). However, the probiotics were effective in restoring vaginal health after cure by showing higher proportion of participants with Nugent Scores < 4 in the probiotic group compared to the control group (87.50% and 71.43% on day 14, 93.75% and 88.89% on day 30, and 77.78% and 66.67% on day 90). The relative abundance of the probiotic strains was significantly increased in the intestinal microbiome of the probiotic group compared to the control group at day 14, but no significance was detected after 30 and 90 days. Also, the probiotics were not detected in vaginal microbiome, suggesting that L. gasseri TM13 and L. crispatus LG55 mainly acted through the intestine. A higher abundance of Prevotella timonensis at baseline was significantly associated with long-term cure failure of BV and greatly contributed to the enrichment of the lipid IVA synthesis pathway, which could aggravate inflammation response. To sum up, L. gasseri TM13 and L. crispatus LG55 can restore the vaginal health of patients recovering from BV, and individualized intervention mode should be developed to restore the vaginal health of patients recovering from BV.

Previous research has shown that the use of melatonin by individuals with irritable bowel syndrome (IBS) has improved symptoms and quality of life (QoL) but did not affect sleep. This research has been shown to have some limitations in that it has been conducted in a small number of individuals and did not use the latest IBS diagnostic criteria. This randomised control trial aimed to determine in 136 individuals with IBS with and without sleep disorders the effects of melatonin on IBS score, gastrointestinal (GI) symptoms, QoL, and sleep. The results showed that compared to placebo, the use of melatonin for 8 weeks resulted in improved IBS score and GI symptoms in individuals with and without sleep disorders. Severity and frequency of abdominal pain, satisfaction with bowel habits, disease impacts on life, and stool consistency were all improved, however frequency of defecations was unaffected. Sleep was improved in those with sleep disorders, but not those without. It was concluded that melatonin can be used to improve IBS and QoL in individuals with or without sleep disorders and may also improve sleep in those with sleep disorders and IBS. This study could be used by healthcare professionals to recommend the use of melatonin to individuals with IBS to improve symptoms and QoL.
Abstract
BACKGROUND Irritable bowel syndrome (IBS) is one of the world's most common gastrointestinal (GI) disorders, and current treatments do not meet patients' demands. This study aimed to investigate melatonin's therapeutic effects on IBS score, GI symptoms, quality of life, and sleep parameters in both groups of IBS patients with and without sleep disorders. METHODS In this randomized double-blinded placebo-controlled trial study, 136 patients with a diagnosis of IBS based on ROME IV criteria were enrolled and then divided into two groups respecting having sleep disorders or not. Patients of each group were randomized in a 1:1 ratio to receive melatonin 6 mg daily (3 mg fasting and 3 mg at bedtime) for 2 months (8 weeks). Blocked randomization was used in this process. All patients were evaluated both at the beginning and the end of the trial regarding IBS score, GI symptoms, quality of life, and sleep parameters through valid questionnaires. RESULTS In both groups of patients with and without sleep disorders, a significant improvement was observed in IBS score and GI symptoms, including the severity and the frequency of abdominal pain, the severity of abdominal bloating, satisfaction with bowel habits, disease's impact on patient's life, and stool consistency; however, there was no significant improvement in the frequency of defecations per week. In patients with sleep disorders, significant improvement in sleep parameters, including subjective sleep quality, sleep latency, sleep duration, sleep efficiency, and daytime dysfunction, was observed, while in patients without sleep disorders, there was no significant improvement in sleep parameters. In addition, quality-of-life improvement was observed in a significant number of melatonin recipients compared to placebo in both groups of patients. CONCLUSION Melatonin can be considered an effective treatment for improving IBS score, GI symptoms, and quality of life in IBS patients with and without sleep disorders. It is also effective to improve sleep parameters in IBS patients with sleep disorders.

The regular intake of foods rich in polyphenols shows many biological activities, such as antioxidant, cardioprotective, anti-inflammation and anti-aging properties. This diversity of compounds found in grapes, especially red grapes, makes it a candidate for testing the role of dietary polyphenols to health. The objective of this single blinded randomised controlled clinical trial was to evaluate the effects of consuming 50g of Málaga muscatel raisins which are dried grapes on cognitive performance, quality of life, and functional activities in healthy adults over 70 years. According to the researchers this is the first study looking at the effect of raisins on cognitive performance. A group of 80 participants were split into two groups with one group adding 50g of raisins a day to their usual diet for six months and a control group of 40 patients receiving no raisins. Cognitive performance was measured by various tests which are summarised in the full text article. The results of this study showed that the supplement of 50 g of raisins slightly improved cognitive performance including spatial orientation, memory and comprehension, reading, writing, and drawing. In addition to a slight improvement in quality of life and functional activities. This shows promising results and that the addition of raisins to the diet along with a variety of foods rich in polyphenols can confer positive health benefits that can prevent age related cognitive decline. More research is needed to know exactly the mechanism of action of polyphenols on cognitive performance.
Abstract
The objective of this study was to evaluate the effects of consuming 50 g of raisins on cognitive performance, quality of life, and functional activities in healthy older adults. This is a parallel randomized controlled clinical trial, in which 80 subjects over 70 years of age participated. For 6 months, the intervention group (IG; n = 40) consumed 50 g of raisins per day added to their usual diet, whereas the control group (CG; n = 40) received no supplement. All variables were measured at baseline and at 6 months. Cognitive performance assessed with the Montreal Cognitive Assessment (MOCA) test shows a difference of 3.27 points (95% CI 1.59 to 4.96), p ≤ 0.001, favorable to the IG, after the intervention. Among the cognitive performances, an improvement is observed in the IG in orientation, assessed both with the MOCA test 0.49 (95% CI 0.10 to 0.87), p = 0.014, and with the Mini-Mental State Examination (MMSE) test, 0.36 (95% CI 0.02 to 0.70), p = 0.038. In visuospatial/executive capacity and in language, improvements were also observed in the IG, 1.36 (95% CI 0.77 to 1.95), p = 0.001, and 0.54 points (95% CI 0.12 to 0.96), p = 0.014, respectively. Immediate and delayed recall, assessed with the Rey Auditory Verbal Learning Test, improved in the IG. In addition, the IG showed a better quality of life and greater autonomy in instrumental activities of daily living after 6 months. No significant changes were observed in the rest of the variables analyzed. Therefore, the consumption of 50 g of raisins produces a slight improvement in cognitive performance, quality of life, and functional activities in the elderly.
