Cardiovascular disease is the leading cause of morbidity and mortality in developed countries. Internet-based interventions are a promising strategy for promoting healthy lifestyle behaviours. The aim of this study was to investigate the short- and long-term efficacy of a self-administered internet-based intervention aimed at promoting lifestyle changes in patients who are obese with hypertension. The study is a randomized wait-list controlled trial which recruited 105 adults with hypertension who were overweight or obese and randomly assigned to either a 3-month internet-based intervention group (n=55) or the wait-list control group (n=50). Results showed a significant decrease in the body mass index, body fat mass and blood glucose (blood sugar) levels at 3 months in the internet-based intervention group. In addition, there was a favourable trend towards a relation to blood pressure, which reached statistical significance at the 12-month follow-up. Authors conclude that simple strategies that can easily be incorporated into daily living in a scalable and cost-effective way can empower patients by educating them about health, thus, increasing their confidence and promoting self-management.
Abstract
BACKGROUND Internet-based interventions are a promising strategy for promoting healthy lifestyle behaviors. These have a tremendous potential for delivering electronic health interventions in scalable and cost-effective ways. There is strong evidence that the use of these programs can lead to weight loss and can lower patients' average blood pressure (BP) levels. So far, few studies have investigated the effects of internet-based programs on patients who are obese with hypertension (HTN). OBJECTIVE The aim of this study is to investigate the short- and long-term efficacy, in terms of body composition and BP parameters, of a self-administered internet-based intervention involving different modules and learning techniques aimed at promoting lifestyle changes (both physical activity and healthy eating) in patients who are obese with HTN. METHODS A randomized wait-list controlled trial design was used. We recruited 105 adults with HTN who were overweight or obese and randomly assigned them to either a 3-month internet-based intervention group (n=55) or the wait-list control group (n=50). We assessed BMI (primary outcome), body fat mass (BFM), systolic (S)BP and diastolic (D)BP, blood glucose and insulin levels, physical activity levels, and functional capacity for aerobic exercise at Time 0 (preintervention) and Time 1 (postintervention). All the patients in the wait-list control group subsequently received the intervention, and a secondary within-group analysis, which also included these participants, was conducted at Time 2 (12-month follow-up). RESULTS A 2-way mixed analysis of covariance showed a significant decrease in BMI, BFM, and blood glucose at 3 months in the internet-based intervention group; the effect size for the BMI and BFM parameters was moderate to large, and there was also a borderline significant trend for DBP and insulin. These results were either maintained or improved upon at Time 2 and showed significant changes for BMI (mean difference -0.4, 95% CI -0.1 to -0.6; P=.005), BFM (mean difference -2.4, 95% CI -1.1 to -3.6; P<.001), DBP (mean difference -1.8, 95% CI -0.2 to -3.3; P=.03), and blood glucose (mean difference -2, 95% CI 0 to -4; P=.04). CONCLUSIONS Implementation of our self-administered internet-based intervention, which involved different learning techniques aimed to promote lifestyle changes, resulted in positive short- and long-term health benefits in patients who are obese with HTN.

Plain language summary
Literature shows that 75% of the adult population worldwide experience vitamin D deficiency, of whom 13% fall under the category of extremely severe vitamin D deficiency (<10 ng/ml). The aim of this retrospective study was to compare the Vitamin D status of children with tumours or without. A secondary aim was to analyse the effects of vitamin D supplementation (as a complement to cancer treatment) on the vitamin D levels of children. The study included 173 children (males n=96; females n=77) aged between 0 and 18 who were treated for cancer. The control group consisted of 569 (males n=310; females n=259) children, aged 0 to 4 who received treatment at the clinic for reasons other than cancer. Results indicate that initial Vitamin D levels were significantly lower among children with cancer (19% lower than in the control group). A correlation between insufficient and deficient initial serum vitamin D levels and unfavourable prognosis was found. Authors suggest that vitamin D supplementation would be most efficient if medicine would follow the present trend of personalised therapy.
Abstract
undefined: : Our aims were to compare the vitamin D status of children with and without cancer and to examine the possible correlation between vitamin D levels in children with cancer before initiating treatment and prognosis. We compared the data of 173 children with cancer with those of 569 children without cancer. We measured a significant difference ( = 1.34E-08) between the vitamin D levels of children with cancer before treatment and children without cancer. There was a significant correlation between the initial vitamin D levels of children with cancer and the prognosis ( = 0.016, odds ratio = 51.33) at 5% significance. The average vitamin D level was 19.76% lower in the population with cancer compared with the average of the control group, and we found a correlation between the lower vitamin D levels in children with cancer and the adverse prognosis. We suggest that supplying vitamin D is reasonable and a prospective study of vitamin D in pediatric patients with cancer is recommended.

Plain language summary
Multicomponent interventions consisting of dietary modification, physical activity, behavioural therapy, and education have shown to improve body mass index, blood pressure, and lipids profile. The Obemat2.0 trail was designed and conducted to implement and to test the efficacy of a structured multicomponent motivational therapy to treat childhood obesity. The study is a randomised clustered clinical trial with a treatment on children with obesity lasting 12 months. The study had two arms: a control group and an intervention group. The recruitment started in June 2016 and the fieldwork is expected to end in June 2019. The study results will show whether a multicomponent program, including a bundle of motivational strategies conducted in primary centres by therapists with 12h of specific training could be more effective than usual care. Authors expect this clinical trial to open a window of opportunity to support professionals at the primary care level to treat childhood obesity.
Abstract
The primary aim of the Obemat2.0 trial was to evaluate the efficacy of a multicomponent motivational program for the treatment of childhood obesity, coordinated between primary care and hospital specialized services, compared to the usual intervention performed in primary care. This was a cluster randomized clinical trial conducted in Spain, with two intervention arms: motivational intervention group vs. usual care group (as control), including 167 participants in each. The motivational intervention consisted of motivational interviewing, educational materials, use of an eHealth physical activity monitor and three group-based sessions. The primary outcome was body mass index (BMI) z score increments before and after the 12 (+3) months of intervention. Secondary outcomes (pre-post intervention) were: adherence to treatment, waist circumference (cm), fat mass index (z score), fat free mass index (z score), total body water (kg), bone mineral density (z score), blood lipids profile, glucose metabolism, and psychosocial problems. Other assessments (pre and post-intervention) were: sociodemographic information, physical activity, sedentary activity, neuropsychological testing, perception of body image, quality of the diet, food frequency consumption and foods available at home. The results of this clinical trial could open a window of opportunity to support professionals at the primary care to treat childhood obesity. The clinicaltrials.gov identifier was NCT02889406.

Plain language summary
The Mediterranean diet is characterised by an abundant consumption of extra-virgin olive oil, fruits, vegetables, nuts, and legumes, a moderate consumption of fish and seafood, poultry, fermented dairy products, and red wine with meals, and low intakes of sweetened beverages, red meat and ready meals. The aim of the study was to evaluate the association between adherence to a Mediterranean diet and physical activity on pulmonary function in a large middle-aged population at low-to-moderate cardiovascular risk. The study is an ongoing study that between 2015 and 2017 enrolled a total of 3020 subjects – women aged between 50 to 70 years and men aged between 45 to 65 years – with the presence of at least one cardiovascular risk factor. Results indicate that a low adherence to the Mediterranean diet was linked with impaired breathing patterns and higher prevalence of abnormal lung function when compared to participants with a higher adherence to this dietary pattern. Additionally, vigorous physical activity was accompanied by better results in lung function than that observed in inactive subjects. The study provides initial clinical evidence about the independent and deleterious effect of both low adherence to the Mediterranean diet and low physical activity practice on lung function in participants without known pulmonary disease.
Abstract
undefined: A few studies showed that both adherence to Mediterranean diet (MedDiet) and physical activity practice have a positive impact on pulmonary function in subjects with lung disease. These associations are not well studied in subjects free from lung disease. In a cross-sectional study conducted in 3020 middle-aged subjects free of lung disease, adherence to the MedDiet using the Mediterranean Diet Adherence Screener, and physical activity practice using the International Physical Activity Questionnaire short form were recorded. Respiratory function was assessed using forced spirometry and the results were evaluated according to the Global initiative for Chronic Obstructive Lung Disease. Logistic regression models were used to analyze the associations between adherence to the MedDiet and physical activity practice with the presence of ventilatory defects. Participants with a high adherence to MedDiet, in comparison to those with low adherence, had both higher forced vital capacity (FVC; 100 (87⁻109) vs. 94 (82⁻105) % of predicted, = 0.003) and forced expired volume in the first second (FEV1; 100 (89⁻112) vs. 93 (80⁻107) % of predicted, < 0.001). According to their degree of physical activity, those subjects with a high adherence also had both higher FVC (100 (88⁻107) vs. 94 (83⁻105) % of predicted, = 0.027) and FEV1 (100 (89⁻110) vs. 95 (84⁻108) % of predicted, = 0.047) in comparison with those with low adherence. The multivariable logistic regression models showed a significant and independent association between both low adherence to MedDiet and low physical activity practice, and the presence of altered pulmonary patterns, with differences between men and women. However, no joint effect between adherence to MedDiet and physical activity practice on respiratory function values was observed. Low adherence to MedDiet and low physical activity practice were independently associated with pulmonary impairment. Therefore, the lung mechanics seem to benefit from heart-healthy lifestyle behaviors.

Plain language summary
Plant-based diets rich in fruits, vegetables, whole grains, nuts, and legumes are consistently linked to reduced risk for chronic disease, improved cognition, and longevity. The aim of the study was to examine the diet quality and blood metabolites of vegetarian and omnivore adults to determine adherence to plant-based diets compared to high-quality eating patterns. The study is a cross-sectional investigation. Thirty-three participants (17 vegetarians: 3 men/14 women; 16 omnivores: 3 men/13 women) aged between 18 and 65 years were enrolled for the study. Results indicate the health biomarkers did not differ between vegetarians and omnivores matched for gender, age, and adiposity. However, when participants were regrouped by low-quality versus high-quality diets, data suggests that several common health biomarkers are more closely aligned with diet quality attributes than with plant-based diet categorisation. Authors conclude that healthcare practitioners should emphasize diet quality in their messages to their clients and discuss the importance of eating whole, minimally processed foods with less added fat and sugars.
Abstract
undefined: Although plant-based diets are promoted for healthy outcomes, these diets are not synonymous with high-quality diets. Plant-based diets can include highly processed, less healthful foods, including savory snacks, pastries, and sugary fruit drinks. This cross-sectional study examined the diet quality of vegetarian and omnivorous adults, matched for gender, age, and adiposity, and related diet quality to standard health biomarkers. Diet quality was assessed using the Rapid Eating and Activity Assessment for Participants Short Version questionnaire. Participants (17 vegetarians and 16 omnivores; 28.2 ± 8.9 years; 22.5 ± 2.7 kg/m ) were non-smokers and healthy by self-report. The median duration of adherence to the vegetarian diet was 27 months. Physical activity level and diet quality did not differ significantly between diet groups. Moreover, health biomarkers did not differ by diet groups. When participants were regrouped by low versus high diet quality, health biomarkers differed significantly between groups for fasting insulin, HOMA-IR, triglyceride (TG)/HDL ratio, and blood folate, with more favorable levels in the group with high diet quality. These data suggest that health biomarkers more closely align with diet quality attributes than with plant-based diet categorization. Thus, messaging focused on healthy diet attributes may lead to better health outcomes than the simple promotion of plant-based diets.

Plain language summary
An increasing body of evidence suggests that the gut microbiota has a profound impact on human health. While the microbiome of a healthy individual is relatively stable, gut microbial dynamics can be influenced by host lifestyle and dietary choices. The aim of this study was to investigate the effects of mixed spices (cinnamon, oregano, ginger, black pepper, and cayenne pepper) at culinary doses consumed over 2 weeks in a standardized 5g capsule on the production of gut microbiota and short-chain fatty acids The study is a randomised, placebo-controlled, double-blind pilot study carried out with a total of 31 healthy women and men aged between 18 and 65. The subjects were randomly allocated to one of the two intervention groups. Results indicate that daily intake of 5g of mixed spices for 2 weeks in healthy subjects resulted in a significant reduction in the relative abundance of the phylum Firmicutes (bacteria), and a trend of increasing in phylum Bacteroidetes (bacteria) as compared with a matched control group. Authors conclude that a mixture of spices at culinary doses affects the composition of gut microbiota.
Abstract
undefined: Spices were used as food preservatives prior to the advent of refrigeration, suggesting the possibility of effects on microbiota. Previous studies have shown prebiotic activities in animals and in vitro, but there has not been a demonstration of prebiotic or postbiotic effects at culinary doses in humans. In this randomized placebo-controlled study, we determined in twenty-nine healthy adults the effects on the gut microbiota of the consumption daily of capsules containing 5 g of mixed spices at culinary doses by comparison to a matched control group consuming a maltodextrin placebo capsule. The 16S ribosomal RNA sequencing data were used for microbial characterization. Spice consumption resulted in a significant reduction in Firmicutes abundance ( < 0.033) and a trend of enrichment in Bacteroidetes ( < 0.097) compared to placebo group. Twenty-six operational taxonomic units (OTUs) were different between the spice and placebo groups after intervention. Furthermore, there was a significant negative correlation between fecal short-chain fatty acid propionate concentration and Firmicutes abundance in spice intervention group ( < 0.04). The production of individual fecal short-chain fatty acid was not significantly changed by spice consumption in this study. Mixed spices consumption significantly modified gut microbiota, suggesting a prebiotic effect of spice consumption at culinary doses.

Children and adolescents with obesity are at a high risk of being obese in adulthood. The aim of this study was to develop a multidisciplinary lifestyle intervention program targeted at children and adolescents with moderate to severe obesity. The study is based on the Intervention for Childhood and Adolescents Obesity via Activity and Nutrition (ICAAN) – quasi-experimental intervention trial - which recruited 103 participants aged between 6 and sixteen years (63 were boys and 40 girls). The study was based on 2 active treatment groups (usual care group vs exercise group) receiving a 16-week intervention program. Results indicate that children and adolescents with obesity can achieve positive effects on body composition, physical fitness, and cardiometabolic markers, particularly with the exercise intervention. Authors conclude that the moderate-intensity multidisciplinary lifestyle intervention program they developed, can be sustained in the real-world setting and it is applicable to both moderate and severe obesity.
Abstract
undefined: This study aimed to develop a multidisciplinary lifestyle intervention program targeted at children and adolescents with moderate to severe obesity, and assess the additional effects of exercise intervention when compared to usual care. Overall, the 103 enrolled participants were ≥85th percentile of age and sex-specific body mass index (BMI). Participants were divided into groups that received 16 weeks of either usual care or exercise intervention. The BMI -score of the overall completers decreased by about 0.05 after the 16-week intervention ( = 0.02). After the intervention, only the exercise group had a significantly lower BMI -score than the baseline score by about 0.1 ( = 0.03), but no significant group by time interaction effects were observed. At the 16-week follow-up, significant group by time interaction effects were observed in percentage body fat (%BF) (β = -1.52, 95%CI = -2.58⁻-0.45), lean body mass (LM) (β = 1.20, 95%CI = 0.12⁻2.29), diastolic blood pressure (β = -5.24, 95%CI = -9.66⁻-0.83), high-sensitivity C-reactive protein (β = -1.67, 95%CI = -2.77⁻-1.01), and wall sit test score (β = 50.74, 95%CI = 32.30⁻69.18). We developed a moderate-intensity intervention program that can be sustained in the real-world setting and is practically applicable to both moderate and severe obesity. After interventions, the exercise group had lower %BF and cardiometabolic risk markers, and higher LM and leg muscle strength compared to the usual care group.

Most of the financial burden of diabetes mellitus is related to management of its complications, and chronic kidney disease is the most expensive and debilitating. The aim of the study was to evaluate the effect of dietary fibre (supplemental or dietary pattern rich in fibre) on diabetic kidney disease. The study is a systemic review that included seven interventional clinical trials that comprised 161 patients with diabetes with an age range of 20 to 74 years. The mean fibre intake in the intervention was 24 g/day and 16 g/day in the control group. Results indicate that only the vegetarian dietary pattern was associated with beneficial kidney outcomes in both type 1 and type 2 diabetes mellitus. There were no other dietary patterns that had favourable effects on kidney outcomes. Authors conclude that a vegetarian dietary pattern may have a beneficial effects on renal outcomes.
Abstract
Fiber intake is associated with better glycemic control being an important nonpharmacologicaltreatment for diabetes (DM). We hypothesize that a dietary fiber intake can bringbenefits to diabetic kidney disease (DKD), improving renal outcomes. This systematic review aimedto evaluate the effect of dietary fiber (supplemental or dietary pattern rich in fiber) on DKD. Wesearched six databases to identify clinical trials that reported fiber intake and renal outcomes(albuminuria, proteinuria, estimated glomerular filtration rate (eGFR) dialysis) in patients with DM.From 1814 studies, 48 papers were fully evaluated. In the end, seven trials (161 patients, aged 58.3years, 49% females) were included. The studies were organized into three categories (vegetarian,Dietary Approaches to Stop Hypertension (DASH) diet, and fiber supplement), two evaluatedsupplements and five dietary patterns. Vegetarian diet reduced albuminuria in three trials, two inpatients with type 1 DM and one in patients with type 2 DM; and one study demonstrated a change inthe eGFR in type 1 DM. The individual quality of the studies was low/uncertain. A vegetarian dietarypattern may have a beneficial effect on these renal outcomes. However, the individual effect of theintake of fiber on DKD not was possible to be evaluated.

The identification of modifiable risk factors is vital for the reduction of the growing diabetes epidemic. Diet is one such lifestyle factor that might play a key role in the prevention of diabetes. The aim of the study was to investigate the association between vegetarianism and diabetes in a large, population-based study of British adults. The study is a prospective study of vegetarianism and diabetes risk in a cohort of 45,314 participants. Results indicate that the low meat eaters, fish eaters and vegetarians had a lower risk of developing diabetes compared to regular meat eaters. Authors conclude that people consuming a low or meat-free diet had a lower risk of hospitalisation or death with diabetes.
Abstract
BACKGROUND The global prevalence of diabetes is high and rapidly increasing. Some previous studies have found that vegetarians might have a lower risk of diabetes than non-vegetarians. OBJECTIVE We examined the association between vegetarianism and risk of hospitalisation or death with diabetes in a large, prospective cohort study of British adults. METHODS The analysed cohort included participants from the European Prospective Investigation into Cancer and Nutrition (EPIC)-Oxford study who were diabetes free at recruitment (1993-2001), with available dietary intake data at baseline, and linked hospital admissions and death data for diabetes over follow-up (n = 45,314). Participants were categorised as regular meat eaters (≥50 g per day: n = 15,181); low meat eaters (<50 g of meat per day: n = 7615); fish eaters (ate no meat but consumed fish: n = 7092); and vegetarians (ate no meat or fish, including vegans: n = 15,426). We used multivariable Cox proportional hazards models to assess associations between diet group and risk of diabetes. RESULTS Over a mean of 17.6 years of follow-up, 1224 incident cases of diabetes were recorded. Compared with regular meat eaters, the low meat eaters, fish eaters, and vegetarians were less likely to develop diabetes (hazard ratio (HR) = 0.63, 95% confidence interval (CI) 0.54-0.75; HR = 0.47, 95% CI 0.38-0.59; and HR = 0.63, 95% CI 0.54-0.74, respectively). These associations were substantially attenuated after adjusting for body mass index (BMI) (low meat eaters: HR = 0.78, 95% CI 0.66-0.92; fish eaters: HR = 0.64, 95% CI 0.51-0.80; and vegetarians: HR = 0.89, 95% CI 0.76-1.05). CONCLUSIONS Low meat and non-meat eaters had a lower risk of diabetes, in part because of a lower BMI.

Plain language summary
Obesity substantially increases the risk of type 2 diabetes, cardiovascular disease, and certain types of cancer. Lifestyle change, including improved dietary choices, represents a primary prevention tool. The study’s hypothesis is that plant-based meal produces higher levels of gastrointestinal hormones and increased satiety in men with type 2 diabetes or obesity while having a negligible effect on healthy men. The study is randomised crossover study which enrolled 60 men aged between 30 – 65 years: 20 men diagnosed with type 2 diabetes, 20 obese and 20 healthy controls with two interventions (vegan or processed meat meal). Results indicate that greater satiety was reported by all men following the vegan meal. The difference between the meals was noticeable also in healthy volunteers. Authors conclude that plant-based meals with tofu may be an effective tool to increase postprandial (after a meal) secretion of gastrointestinal hormones, as wells as promote satiety, compared to processed meat and cheese in healthy, obese and diabetic men.
Abstract
undefined: Gastrointestinal hormones are involved in regulation of glucose metabolism and satiety. We tested the acute effect of meal composition on these hormones in three population groups. A randomized crossover design was used to examine the effects of two energy- and macronutrient-matched meals: a processed-meat and cheese (M-meal) and a vegan meal with tofu (V-meal) on gastrointestinal hormones, and satiety in men with type 2 diabetes (T2D, = 20), obese men (O, = 20), and healthy men (H, = 20). Plasma concentrations of glucagon-like peptide -1 (GLP-1), amylin, and peptide YY (PYY) were determined at 0, 30, 60, 120 and 180 min. Visual analogue scale was used to assess satiety. We used repeated-measures Analysis of variance (ANOVA) for statistical analysis. Postprandial secretion of GLP-1 increased after the V-meal in T2D (by 30.5%; 95%CI 21.2 to 40.7%; < 0.001) and H (by 15.8%; 95%CI 8.6 to 23.5%; = 0.01). Postprandial plasma concentrations of amylin increased in in all groups after the V-meal: by 15.7% in T2D (95%CI 11.8 to 19.6%; < 0.001); by 11.5% in O (95%CI 7.8 to 15.3%; = 0.03); and by 13.8% in H (95%CI 8.4 to 19.5%; < 0.001). An increase in postprandial values of PYY after the V-meal was significant only in H (by 18.9%; 95%CI 7.5 to 31.3%; = 0.03). Satiety was greater in all participants after the V-meal: by 9% in T2D (95%CI 4.4 to 13.6%; = 0.004); by 18.7% in O (95%CI 12.8 to 24.6%; < 0.001); and by 25% in H (95%CI 18.2 to 31.7%; < 0.001). Our results indicate there is an increase in gut hormones and satiety, following consumption of a single plant-based meal with tofu when compared with an energy- and macronutrient-matched processed-meat meat and cheese meal, in healthy, obese and diabetic men.
