Plain language summary
Studies have shown that a starch and sucrose-reduced diet (SSRD) leads to considerable improvements of gastrointestinal and extraintestinal symptoms in patients with irritable bowel syndrome (IBS). The purpose of this pilot study was to see if a SSRD would be beneficial in other conditions with similar symptoms. Two people took part in the study. A man with functional diarrhoea and a woman with microscopic colitis. The SSRD consists of low intakes of sugar-rich products, but continued or increased intakes of all meats and fish, fat, natural dairy products, eggs, berries, fruits, nuts, seeds, and vegetables low in starch. Fiber-rich bread and pasta and raw or wild rice were recommended instead of white bread and more processed rice and pasta. During the 4-week intervention, the participants lost weight and waist circumference reduced. The degree of satiety after a meal was increased and the sweet cravings were strongly reduced. The gastrointestinal symptoms improved in the participant with diarrhoea but was unaffected in the participant with microscopic colitis. Reductions of diarrhoea and of bloating and flatulence were most pronounced in both patients. The psychological well-being was improved during the intervention. Extraintestinal symptoms were also reduced during the SSRD, especially urinary urgency and belching. This is a small intervention study and therefore not possible to make generalised claims or recommendations. However, healthcare practitioners could look at SSRD when working with IBS patients as a therapeutic dietary option.
Abstract
OBJECTIVES A starch- and sucrose-reduced diet has been found to improve gastrointestinal and extraintestinal symptoms in irritable bowel syndrome, as well as reduce weight and improve psychological well-being. Our hypothesis was that a starch- and sucrose-reduced diet would also be beneficial in other conditions with similar symptoms. The aim of the present research letter was to describe the role of a starch- and sucrose-reduced diet in a pilot project in patients with diarrhea having varying causes. METHODS One man, age 36 y, suffering from functional diarrhea and one woman, 56 y, suffering from microscopic colitis, were randomized to a starch- and sucrose-reduced diet for 4 wk. At baseline, dietary information was given, and blood samples collected. Weight and waist circumference were measured. The participants completed the irritable bowel syndrome severity scoring system for evaluating specific gastrointestinal and extraintestinal symptoms and visual analog scale for irritable bowel syndrome for evaluation of specific gastrointestinal symptoms and psychological well-being. The degrees of satiety and sweet craving were measured on visual analog scales. After 4 wk, all procedures were repeated. RESULTS Weight, body mass index, and waist circumference were decreased during the intervention. The total amount of gastrointestinal symptoms was decreased in the participants with functional diarrhea, and diarrhea and bloating were decreased in both participants. Both had reduced extraintestinal symptoms and improved psychological well-being. Blood levels had mainly unchanged or slightly increased values of measurements reflecting nutrient intake. CONCLUSIONS A starch- and sucrose-reduced diet may lead to weight reduction, reduced symptoms, and improved well-being in several patient categories, not only in patients suffering from irritable bowel syndrome. Future randomized trials should be done.

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.

Humans lose skeletal muscle with advancing age, and this can progress to sarcopenia. Dietary protein is crucial for maintaining skeletal muscle health; however, several factors can lead to reduced protein intake in older age. The aim of this study was to test whether the addition of gut microbiome modulation could augment established muscle function improvements from combined protein (branched chain amino acids [BCAA]) and resistance exercise. This study was based on the PROMOTe (effect of PRebiotic and prOtein on Muscle in Older Twins) trial which was a randomised controlled trial in which twin pairs (n= 72) were randomised, one twin to each study arm. Results showed that prebiotics improved cognition but did not impact muscle strength and function, compared with placebo. Furthermore, gut microbiome modulation via prebiotic supplementation in the context of ageing-muscle research is feasible and well tolerated, with clear responses noted in the gut microbiota composition and function. Authors concluded that cheap and readily available gut microbiome interventions hold promise for improving cognitive frailty in our ageing population.
Abstract
Studies suggest that inducing gut microbiota changes may alter both muscle physiology and cognitive behaviour. Gut microbiota may play a role in both anabolic resistance of older muscle, and cognition. In this placebo controlled double blinded randomised controlled trial of 36 twin pairs (72 individuals), aged ≥60, each twin pair are block randomised to receive either placebo or prebiotic daily for 12 weeks. Resistance exercise and branched chain amino acid (BCAA) supplementation is prescribed to all participants. Outcomes are physical function and cognition. The trial is carried out remotely using video visits, online questionnaires and cognitive testing, and posting of equipment and biological samples. The prebiotic supplement is well tolerated and results in a changed gut microbiome [e.g., increased relative Bifidobacterium abundance]. There is no significant difference between prebiotic and placebo for the primary outcome of chair rise time (β = 0.579; 95% CI -1.080-2.239 p = 0.494). The prebiotic improves cognition (factor score versus placebo (β = -0.482; 95% CI,-0.813, -0.141; p = 0.014)). Our results demonstrate that cheap and readily available gut microbiome interventions may improve cognition in our ageing population. We illustrate the feasibility of remotely delivered trials for older people, which could reduce under-representation of older people in clinical trials. ClinicalTrials.gov registration: NCT04309292.

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.

The term “healthy ageing” describes the ideal status of ageing while maintaining independence and quality of life in older adults while simultaneously delaying premature ageing and incident frailty. The start and progression of health deterioration varies between individuals. One of the best ways to assess ageing, as a dynamic process, is by long-term trajectories of functioning. The aim of this study was to assess the trajectories between healthy ageing status and frailty, including not only the progression in health deterioration but also improvement from unhealthier to healthier states, among community-dwelling adults 70 years and older without major comorbidities over 4 years of follow-up. This study is a secondary analysis of the multicentre, randomised clinical trial DO-HEALTH, designed to evaluate the effects of omega-3, vitamin D, and a home strength exercise programme. Participants were 2,157 community-dwelling older adults 70 years and older. Results show dynamic trajectories of ageing in a third of all participants, with 12.0% improving to a better and 22.8% declining to a lower healthy ageing state. Additionally, in the multivariate adjusted analyses, the odds of improvement to a healthier state declined by 6% for each additional year of age, while the odds of deteriorating were 35% higher for women. Authors conclude that since their findings show that women have a 35% lower chance to improve to a healthier state should be taken into consideration in future efforts to support healthy ageing in the older adult population.
Abstract
INTRODUCTION Ageing trajectories range from delayed ageing with extended health to accelerated ageing, with an increased risk of frailty. We evaluated the prevalence and prospective change between health states among community-dwelling European older adults. METHODS This prospective study is a secondary analysis of DO-HEALTH, a randomized trial that included adults aged 70 years and older across 5 European countries. Healthy agers (HA) fulfilled the Nurses' Health Study healthy ageing criteria and accelerated agers were non-HA being at least pre-frail according to the Fried frailty criteria. We assessed the proportion of participants changing between health states over 4 assessments and evaluated the odds of changing to a more favourable category. To increase reliability and avoid regression to the mean, we averaged the first 2 years and compared them to the average of the last 2 years. RESULTS Of 2,157 participants, 12.4% were excluded for meeting both healthy ageing and pre-frailty criteria simultaneously. Among the remaining 1,889 participants (mean age 75.1 years, 60.9% female), 23.1% were initially HA, 44.4% were non-HA but not pre-frail, and 32.6% were pre-frail or frail. Subsequently, 65.3% remained in the same health state, 12.0% improved to a healthier state, and 22.8% progressed to a less advantageous state. After adjusting for sex, study centre, treatment, and body mass index, each year of age was associated with 6% lower odds of improving health states. Women had 35% higher odds than men of following a disadvantageous trajectory. CONCLUSION We observed dynamic trajectories of ageing where transitioning to a healthier state became less likely with advancing age and among women.

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.

An anal fissure is a condition resulting from a superficial open wound or tear in the anus mucosa with a sharp pain that can extend from the anal canal to the periphery. The aim of this study was to evaluate the effect of oral L-arginine as a safer method with better performance on clinical symptoms, quality of life, and internal anal sphincter pressure in patients with chronic anal fissure. This study is a randomised, double-blind, placebo-controlled trial with parallel design conducted in the 4-week intervention and the 8-week follow-up. The study recruited 76 adult men and women who were aged between 18 and 65 years of age and were diagnosed with chronic fissures. Participants were assigned to two groups: 3000 mg l-arginine, or a placebo filled with Maltodextrin. Results show that supplementation with l-arginine may relieve clinical symptoms, especially pain and bleeding, and improve the quality of life of patients with chronic anal fissure. In addition, analysis of anal internal sphincter pressures evaluated by manometry and balloon showed the significant reduction of sphincter pressure in these patients. Authors conclude that l-arginine supplementation may relieve clinical symptoms and improve the quality of life, anxiety, and depression in patients with chronic anal fissures.
Abstract
The hypertonicity of internal anal sphincter resting pressure is one of the main causes of chronic anal fissure. Therefore, the aim of this study was to assess the effect of oral administration of L-arginine on the improvement of the anal fissures by relaxing the internal anal sphincter. Seventy-six chronic anal fissure patients (aged 18-65 years) who were referred to Rasoul-e-Akram Hospital, Tehran, Iran from February 2019 to October 2020 participated in this randomized, double-blind, placebo-controlled trial. Participants were allocated into treatment (L-arginine) and placebo groups. They took a 1000 mg capsule three times a day for 1 month, and then we followed them at the end of the first and third months after the intervention. Clinical symptoms, anal sphincter resting pressure, and quality of life (QoL) were completed at baseline and the end of the study. The analysis of data showed a significant decrease in bleeding, fissure size, and pain for each group; however, in the L-arginine group was more than the control group at the end of the study (P values < 0.001). Following that, a significant increase in QoL was seen just in patients treated with L-arginine (P value = 0.006). In addition, the comparison of anal pressures at baseline and, between groups at the end of the study showed a significant reduction in sphincter pressure in patients treated with L-arginine (P value < 0.001, = 0.049; respectively). The oral administration of 3000 mg L-arginine can heal chronic anal fissures by reducing internal anal sphincter pressure with more negligible side effects. However, we recommend long-term study with more extended follow-up.Clinical trial registry: IRCT20190712044182N1 at Iranian clinical trials, date: 2019-08-27.

Plain language summary
Preterm birth results in a high risk of mortality and is a cause of several morbidities, including extrauterine growth restriction. Despite numerous proven benefits, the concentration of some nutrients in human milk may be too low to meet the high nutritional needs of premature infants. Thus, to ensure optimal growth and development, human milk fortification is recommended for all very low birth weight babies. The primary aim of this study was to determine whether tailored compared to the standard fortification of enteral nutrition improved weight gain velocity in preterm infants born at ≤32 weeks of gestation. This study is a randomised observer- and patient-blinded controlled multicentre superiority trial, with two parallel groups with a 1:1 allocation ratio. Due to shortage of staff, two out of three centres failed to randomise patients. Patients were assigned to standard or tailored enteral nutrition fortification groups. Results show that there is no statistically significant difference in the velocity of weight gain during the supplementation period in infants born before 32 weeks of gestation who received targeted fortification compared to those who received standard fortification. Changes in length and head circumference did not differ between the groups. Authors conclude that targeted milk modification is a strategy that may allow for the optimisation of growth in premature infants; however, feasibility and poor tolerance of feeds may be important obstacles in introducing this strategy to neonatal intensive care unit clinical practice.
Abstract
Human milk is recommended for very low birth weight infants. Their nutritional needs are high, and the fortification of human milk is a standard procedure to optimize growth. Targeted fortification accounts for the variability in human milk composition. It has been a promising alternative to standard fixed-dose fortification, potentially improving short-term growth. In this trial, preterm infants (≤32 weeks of gestation) were randomized to receive human milk after standard fortification (HMF, Nutricia) or tailored fortification with modular components of proteins (Bebilon Bialko, Nutricia), carbohydrates (Polycal, Nutricia), and lipids (Calogen, Nutricia). The intervention started when preterms reached 80 mL/kg/day enteral feeds. Of the target number of 220 newborns, 39 were randomized. The trial was interrupted due to serious intolerance in five cases. There was no significant difference in velocity of weight gain during the supplementation period (primary outcome) in the tailored vs. standard fortification group: 27.01 ± 10.19 g/d vs. 25.84 ± 13.45 g/d, p = 0.0776. Length and head circumference were not significantly different between the groups. We found the feasibility of targeted fortification to be limited in neonatal intensive care unit practice. The trial was registered at clinicaltrials.gov NCT:03775785.

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.

According to the Ecological Systems Theory, obesity risk factors for children interplay between three determinants: child characteristics, familial characteristics, and societal characteristics. Beyond genetic predispositions, behavioural patterns, such as dietary choices, exercise, and sedentary behaviour, can place a child at risk for obesity. The main aims of this study were to increase daily vegetable and fruit intake and physical activity (i.e., active playtime) and reduce sedentary behaviour and screen time among children. This study was a pilot randomised control and intervention study which recruited parents with children aged between 1 and 3 years. A total of 73 eligible participants were enrolled in the study and were randomly assigned to the intervention (n = 37) or control group (n = 36). Results show that: - intervention group had significant improvements in fruit and vegetable intake by 0.91 and 0.54 servings/day, respectively, over the course of two months. - even though children in the intervention group increased their moderate-to-vigorous physical activity, the increase was not significant compared to the control group. - there were significant improvements in comprehensive parental feeding practices. Authors conclude that empowering families through a theory-based, multicomponent eHealth intervention program is a promising approach for improving nutrition and health-related behavioural changes in young children.
Abstract
The purpose of this study was to evaluate a theory-based, multicomponent eHealth intervention aimed at improving child health behaviors and parental psychosocial attributes and feeding practices. A pilot randomized controlled trial was conducted among 73 parents with children (1-3 years). Intervention group participants (IG, n = 37) received theory-based educational videos, cooking tutorials, and text messages with key information for a total of 8 weeks. Control group participants (CG, n = 36) received a booklet about general nutrition recommendations for children. A parent-administered questionnaire was used for data collection at baseline and post-intervention. Linear models were performed using R version 4.1.1. for data analysis. Children in the IG significantly increased their daily intake of fruit (ΔΔ = 0.89 servings, p = 0.00057) and vegetables (ΔΔ = 0.60 servings, p = 0.0037) and decreased use of screen time (ΔΔ = -33.87 min, p = 0.026), compared to the CG. Parents in the IG improved significantly more than the CG in self-efficacy (p = 0.0068) and comprehensive feeding practices (p = 0.0069). There were no significant differences between the study groups for changes in child outcomes, such as physical activity and sedentary behaviors, and parental nutrition knowledge and attitudes.
