In patients with severe mental disorders, motivation to follow a healthy diet and lifestyle might be low. A diet rich in fruits and vegetables may improve metabolic syndrome, cardiovascular health and mental health. This randomised community-based clinical trial included seventy-four patients with severe mental disorders out of which 37.8% of the participants had schizophrenia or related disorders, 29.7% had bipolar disorder, 25.7% had depressive disorder, 4.1% had a personality disorder, and 2.7% had obsessive-compulsive disorder. The intervention group followed a four-week food education programme (DIETMENT) aimed at promoting fruit and vegetable consumption. A five-month post-intervention analysis showed no increase in participants diagnosed with metabolic syndrome in the intervention group, but an increase in participants diagnosed with metabolic syndrome in the control group. There was a significant reduction in the glomerular filtrate rate in the intervention group. In patients with severe mental disorders, more studies should be conducted to examine the health-promoting effects of adding more fruits and vegetables to the diet. Health professionals can use the results of this study to understand how fruits and vegetables contribute to reducing metabolic syndrome and heart disease risk.
Abstract
OBJECTIVES The aim of this study is to determine the metabolic impact of a nutrition education program on metabolic parameters and the presence of metabolic syndrome (MetS). RESULTS Seventy-four patients were included (mean age, 48.7 years [Standard deviation, SD: 10.8], 55.4% men). The diagnoses of SMD were 37.8% schizophrenia and related disorders; 29.7% bipolar disorder; 25.7% depressive disorder; 4.1% personality disorders; and 2.7% obsessive compulsive disorders. Thirty-seven individuals were distributed in both the intervention group (IG) and the control group (CG). In the IG the presence of MetS was 56.3% and in the CG 46.7%, with no statistically significant difference (p = 0.309). At the end of the study, glomerular filtrate decreased in the IG, body mass index and abdominal perimeter increased in both groups, and there were no changes in metabolic parameters between the groups. Between the baseline and the end of the study, there was no increase in the number of patients diagnosed with MetS (14 at both points); and in the CG the increase was from 8 to 12 (p = 0.005). An intervention based on fruit and vegetable intake could prevent progression to MetS in individuals with SMD, decreasing the likelihood of cardiovascular disease. Trial registration The trial was retrospectively registered on International Standard Randomised Controlled Trial Number (ISRCTN) Register on 11 March 2022 (ISRCTN12024347).

Modifiable (behavioural) risk factors such as sedentary lifestyle and low sleep efficiency, are associated with increased mortality risk and disease progression in individuals with cardiovascular disease. The main aim of this study was to evaluate changes in objectively measured lifestyle and health data derived from wearable devices. This study was part of an international, multicenter randomized controlled trial, the Do Cardiac Health Advanced New Generation Ecosystem 2 study. Only the participants (n=70) randomised to the intervention group were analysed. The participants received the devices to monitor their lifestyle and health parameters. Results indicate significant changes over time in the number of steps and activity level. No significant improvement over time was observed in other outcome measures (i.e., blood pressure, weight, and sleep efficiency). Secondary analysis showed demographic (gender, nationality, marital status), clinical (co-morbidities, heart failure), and psychological (anxiety, depression) profiles that were associated with lifestyle measures. Authors conclude that a personalised approach might be the way forward in order to improve health outcomes in the future.
Abstract
The importance of modifying lifestyle factors in order to improve prognosis in cardiac patients is well-known. Current study aims to evaluate the effects of a lifestyle intervention on changes in lifestyle- and health data derived from wearable devices. Cardiac patients from Spain (n = 34) and The Netherlands (n = 36) were included in the current analysis. Data were collected for 210 days, using the Fitbit activity tracker, Beddit sleep tracker, Moves app (GPS tracker), and the Careportal home monitoring system. Locally Weighted Error Sum of Squares regression assessed trajectories of outcome variables. Linear Mixed Effects regression analysis was used to find relevant predictors of improvement deterioration of outcome measures. Analysis showed that Number of Steps and Activity Level significantly changed over time (F = 58.21, p < 0.001; F = 6.33, p = 0.01). No significant changes were observed on blood pressure, weight, and sleep efficiency. Secondary analysis revealed that being male was associated with higher activity levels (F = 12.53, p < 0.001) and higher number of steps (F = 8.44, p < 0.01). Secondary analysis revealed demographic (gender, nationality, marital status), clinical (co-morbidities, heart failure), and psychological (anxiety, depression) profiles that were associated with lifestyle measures. In conclusion results showed that physical activity increased over time and that certain subgroups of patients were more likely to have a better lifestyle behaviors based on their demographic, clinical, and psychological profile. This advocates a personalized approach in future studies in order to change lifestyle in cardiac patients.

Plain language summary
Depression and obesity are significant global health concerns. Depression can significantly impact physical health and reduced immune function. The aim of this study was to examine the potential benefits of a novel group psychological intervention program. The study is a preliminary quasi-experimental (single-arm) before-after pilot trial of a newly developed group-based psychological intervention program for people with depression and comorbid obesity. The program consisted of 10 two-hour group sessions held weekly. A total of 24 participants were recruited to the program across two pilot groups. Results indicate that there was a significant reduction in participants’ depression and anxiety scores by program-end. Some evidence also shows improvements in weight-related negative cognitions. Authors conclude that the group therapy program therefore has considerable potential to be effective in helping people enjoy better mental health and improve health outcomes.
Abstract
BACKGROUND Depression and obesity are significant global health concerns that commonly occur together. An integrated group cognitive behavioural therapy program was therefore developed to simultaneously address comorbid depression and obesity. METHODS Twenty-four participants (63% women, mean age 46 years) who screened positively for depression with a body mass index ≥25 were recruited from a self-referred general population sample. The group therapy program (10 two-hour weekly sessions) was examined in a single-arm, before-after pilot trial, conducted in a behavioural health clinic in Adelaide, Australia. Primary outcomes included survey and assessment-based analyses of depression, anxiety, body image, self-esteem, and weight (kg), assessed at four time-points: baseline, post-intervention, three-months and 12-months post program. Eighteen participants (75%) completed the program and all assessments. RESULTS Significant improvements in depression, anxiety, self-esteem and body shape concern scores, several quality of life domains, eating behaviours and total physical activity (among others) - but not weight - were observed over the course of the trial. CONCLUSIONS Results from this pilot trial suggest that combining interventions for depression and obesity may be useful. Further development of the program, particularly regarding the potential for physical health benefits, and a randomised controlled trial, are warranted. TRIAL REGISTRATION Trial registration: ANZCTR, ACTRN12617001079336, 13 July 2017. Retrospectively registered after date of the first consent (6 July 2017), but before the date of the first intervention session (20 July 2017).

Plain language summary
The prevalence of diabetes is increasing worldwide, and with it, the risk of cardiovascular disease is also increasing. Intermittent fasting has been shown to reduce weight and improve glycaemic control. Weight control and glycaemic control were also improved with probiotic Lacticaseibacillus rhamnosus HN001 supplementation. This pilot, 12-week, double-blinded, two-armed, randomized 1:1 study aimed to investigate the combined effects of intermittent fasting with daily probiotic Lacticaseibacillus rhamnosus HN001 supplementation on glycaemic management in participants with prediabetes. For two days, participants restricted their calorie intake to 600-650 kcal, followed by five days of ad libitum consumption (5:2). Intermittent fasting for 12 weeks improved glycaemic control (reduced HbA1c) and reduced body weight by 5%. The supplementation with Lacticaseibacillus rhamnosus HN001 did not significantly improve these outcomes. Probiotic supplementation significantly improved mental health and social functioning in participants. There is a need for further large, robust studies to assess the effects of intermittent fasting alone and when it is combined with different exercise forms and different prebiotic and probiotic supplements on cardiometabolic markers and mental health. The findings of this study may be useful to healthcare professionals in understanding the effects of fasting on metabolism as well as the psychological benefits of Lacticaseibacillus rhamnosus HN001 supplementation.
Abstract
Both intermittent fasting and specific probiotics have shown promise in improving glucose tolerance with a potential for synergistic effects through alterations to gut microbiota. In this randomized, double-blinded, two-arm feasibility study, we investigated whether intermittent fasting, supplemented with Lacticaseibacillus rhamnosus HN001 probiotic, reduces HbA1c in individuals with prediabetes. All participants with HbA1c 40-50 mmol/mol commenced intermittent fasting (2 days per week of calorie restriction to 600-650 kcal/day) and were randomized 1:1 to either daily probiotic (Lacticaseibacillus rhamnosus HN001) or placebo for 12 weeks. The primary outcome was a change in HbA1c. Secondary outcomes included changes in anthropometry, body composition, glucoregulatory markers, lipids, hunger hormones, liver enzymes, inflammatory markers, gut hormones, calorie and macronutrient intake, quality of life, hunger, mood and eating behavior. Of 33 participants who commenced the trial, 26 participants (mean age 52 years, body mass index (BMI) 34.7 kg/m2) completed the intervention (n = 11 placebo, n = 15 probiotic). HbA1c decreased from 43 ± 2.7 mmol/mol to 41 ± 2.3 mmol/mol, p < 0.001, with average of 5% weight loss. No significant between-group differences were seen in primary or secondary outcomes except for social functioning (p = 0.050) and mental health (p = 0.007) scores as improvements were seen in the probiotic group, but not in the placebo group. This study shows additional psychological benefits of probiotic supplementation during intermittent fasting to achieve weight loss and glycemic improvement in prediabetes.

Plain language summary
Prevention and management of hypertension are major public health challenges worldwide. Psychosocial factors are related to blood pressure and may lead to hypertension. The aim of this study was to examine the long-term antihypertensive, anti-stress, and psychological state-improving effects of eggplant in human participants with normal-high blood pressure and grade 1 hypertension. The study is a randomized, double-blind, placebo-controlled, parallel-group comparative study. The participants were randomized into one of two intervention groups; placebo group or eggplant group. The participants ingested four eggplant powder capsules, or four placebo capsules every day for 12 weeks. Results indicate that continuous intake of eggplant powder improved blood pressure in participants with normal-high blood pressure and grade 1 hypertension. Additionally, eggplant intake improved positive and negative psychosocial states. Authors conclude that eggplant should be utilised as a safe treatment for blood pressure and mental health.
Abstract
Eggplant (Solanum melongena) is a globally popular vegetable and its significant health effect has not been reported in randomized controlled trials. Recently, we reported that eggplant was rich in choline esters, including acetylcholine (ACh), and had an antihypertensive effect in spontaneously hypertensive rats. Here, we evaluated the effects of a continuous intake of eggplant powder on blood pressure (BP), stress, and psychological state (PS) in 100 stressed participants with normal-high BP or grade 1 hypertension in a randomized, double-blind, placebo-controlled, parallel-group comparative study. The participants were randomly assigned to the eggplant or placebo group. Participants in the eggplant group ingested capsules containing eggplant powder (1.2 g/day; 2.3 mg of ACh/day) for 12 weeks, whereas participants in the placebo group ingested placebo capsules. The primary outcome assessed was hospital BP. Secondary outcomes were stress and PS. Eggplant powder intake significantly decreased the hospital diastolic blood pressure (DBP) at week 8 overall and in the normal-high BP group, and the systolic blood pressure (SBP) and DBP at week 12 overall and in the grade 1 hypertension group, compared to those of the placebo group. It also improved negative PSs at week 8 or 12 in the normal-high BP group. This is the first evidence of the BP- and PS-improving effects of eggplant intake in humans. The functional substance responsible for the effects was estimated to be eggplant-derived choline ester, namely ACh.

Plain language summary
Dementia is characterised by severe cognitive impairment and reduced quality of life. Observational studies have demonstrated that populations following a traditional Mediterranean diet experience less cognitive decline and a lowered risk of dementia. The aim of this study was to examine a Mediterranean diet modified to include 2–3 fresh servings of pork each week across measures of cognitive function and well-being. The study is a 24-week parallel randomised controlled crossover design to compare a Mediterranean diet with 2-3 weekly servings of fresh, lean pork (MedPork) and a low-fat control diet (LF). It recruited adults aged 45–80 years due to their increased risk of developing cardiovascular disease. Results indicate that compared with the LF control diet, the MedPork intervention led to higher performance in the cognitive domain of processing speed and higher scores for the SF-36 subscale emotional role functioning. No significant differences were observed for other domains of cognitive function, nor for additional measures of psychological well-being. Authors conclude that the MedPork intervention can improve processing speed and mood in a population at risk of cardiovascular disease and therefore dementia.
Abstract
BACKGROUND The Mediterranean diet may be capable of improving cognitive function. However, the red meat restrictions of the diet could impact long-term adherence in Western populations. The current study therefore examined the cognitive effects of a Mediterranean diet with additional red meat. METHODS A 24-week parallel crossover design compared a Mediterranean diet with 2-3 weekly servings of fresh, lean pork (MedPork) and a low-fat (LF) control diet. Thirty-five participants aged between 45 and 80 years and at risk of cardiovascular disease followed each intervention for 8 weeks, separated by an 8-week washout period. Cognitive function was assessed using the Cambridge Neuropsychological Test Automated Battery. Psychological well-being was measured through the SF-36 Health Survey and mood was measured using the Profile of Mood States (POMS). RESULTS During the MedPork intervention, participants consumed an average of 3 weekly servings of fresh pork. Compared to LF, the MedPork intervention led to higher processing speed performance (p = 0.01) and emotional role functioning (p = 0.03). No other significant differences were observed between diets. CONCLUSION Our findings indicate that a Mediterranean diet inclusive of fresh, lean pork can be adhered to by an older non-Mediterranean population while leading to positive cognitive outcomes.

Plain language summary
Diabetes can cause a number of health complications if not well managed and treated and has the potential to have a huge impact on people’s physical and psychological wellbeing. The aims of this review are to systematically analyse the available literature on plant-based diet interventions targeting and/or including adults with diabetes and to clearly define the benefits on well-being of such interventions. This study is a systemic review of 11 controlled trials, of which 7 were randomised. Results demonstrate that a plant-based diet can significantly improve psychological well-being, quality of life, control of type 2 diabetes measured by glycated haemoglobin [is a form of haemoglobin that is measured primarily to know the average plasma glucose concentration over a three-month period] and a number of physical characteristics in people with type 2 diabetes. Authors conclude that future studies could explore ways of delivering proper nutritional education in order to support participants to follow healthier dietary patterns.
Abstract
Diet interventions have suggested an association between plant-based diets and improvements in psychological well-being, quality of life and glycated hemoglobin (HbA1c) control in populations with diabetes. The aims of this review are to systematically analyze the available literature on plant-based diet interventions targeting diabetes in adults and to clearly define the benefits on well-being of such interventions. This is a systematic review of controlled trials. A computerized systematic literature search was conducted in the following electronic databases: Allied and Complementary Medicine, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, E-Journals, Excerpta Medica Database, MEDLINE, Health Management Information Consortium, PsycARTICLES, PsycINFO, PubMed, SocINDEX and Web of Science. The search strategy retrieved 1240 articles, of which 11 met the inclusion criteria (n=433; mean sample age 54.8 years). Plant-based diets were associated with significant improvement in emotional well-being, physical well-being, depression, quality of life, general health, HbA1c levels, weight, total cholesterol and low-density lipoprotein cholesterol, compared with several diabetic associations' official guidelines and other comparator diets. Plant-based diets can significantly improve psychological health, quality of life, HbA1c levels and weight and therefore the management of diabetes.

The number of people aged 65 years and over with mild vascular cognitive impairment is continuing to increase. Vascular disease can reduce cerebral perfusion, causing oxidative stress and neurodegeneration. Citicoline [pharmaceutical] inhibits apoptosis associated with cerebral ischemia and in several models of neurodegeneration has been able to potentiate neuroplasticity. The aim of this study was to assess the effectiveness and safety of oral citicoline in elderly people with mild vascular cognitive impairment. A total of 349 patients were included in the study who were assigned to open-label treatment with oral citicoline 500 mg twice a day in a fasting state or to no treatment (controls). Results show that citicoline is effective and safe in the treatment of mild vascular cognitive impairment. The treated group showed improvement in MMSE (Mini-Mental State Examination) scores, with an increase of 0.5 points shown over the course of the study. Authors conclude that further studies are required in order to confirm the findings of this study, and to further assess the efficacy and safety of long-term administration of a dietary supplement such as Cytidine-5′-diphosphate choline.
Abstract
BACKGROUND The studio di intervento nel decadimento vascolare lieve (IDEALE study) was an open multicenter Italian study, the aim of which was to assess the effectiveness and safety of oral citicoline in elderly people with mild vascular cognitive impairment. METHODS The study was performed in 349 patients. The active or citicoline group was composed of 265 patients and included 122 men and 143 women of mean age 79.9 ± 7.8 years selected from six Italian regions. Inclusion criteria were age ≥ 65 years, Mini-Mental State Examination (MMSE) score ≥ 21, subjective memory complaints but no evidence of deficits on MMSE, and evidence of vascular lesions on neuroradiology. Those with probable Alzheimer's disease were excluded. The control group consisted of 84 patients, including 36 men and 48 women of mean age 78.9 ± 7.01 (range 67-90) years. Patients included in the study underwent brain computed tomography or magnetic resonance imaging, and plasma dosage of vitamin B12, folate, and thyroid hormones. Functional dependence was investigated by scores on the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales, mood was assessed by the Geriatric Depression Scale (GDS), and behavioral disorders using the Neuropsychiatric Inventory scale. Comorbidity was assessed using the Cumulative Illness Rating Scale. An assessment was made at baseline (T0), after 3 months (T1), and after 9 months (T2, ie, 6 months after T1). The main outcomes were an improvement in MMSE, ADL, and IADL scores in the study group compared with the control group. Side effects were also investigated. The study group was administered oral citicoline 500 mg twice a day throughout the study. RESULTS MMSE scores remained unchanged over time (22.4 ± 4 at T0; 22.7 ± 4 at T1; 22.9 ± 4 at T2), whereas a significant difference was found between the study and control groups, both in T1 and in T2. No differences were found in ADL and IADL scores between the two groups. A slight but not statistically significant difference was found in GDS score between the study and control groups (P = 0.06). No adverse events were recorded. CONCLUSION In this study, citicoline was effective and well tolerated in patients with mild vascular cognitive impairment. Citicoline activates biosynthesis of phospholipids in neuronal membranes, increases brain metabolism as well as norepinephrine and dopamine levels in the central nervous system, and has neuroprotective effects during hypoxia and ischemia. Therefore, citicoline may be recommended for patients with mild vascular cognitive impairment.
