Abstract
INTRODUCTION This randomized trial aimed to compare the effects of moderate-intensity aerobic vs resistance exercise with dietary modification in patients with nonalcoholic fatty liver disease (NAFLD). METHODS Patients with NAFLD were randomly assigned (1:1) to a 12-week supervised training program of moderate-intensity aerobic or resistance exercise with dietary intervention consisting of monthly individual nutritional counseling by a dietician. Transient elastography, anthropometry, body composition, cardiorespiratory fitness, biochemistries, and glucose tolerance were measured at baseline and 12 weeks. RESULTS Eighteen subjects exercised for an average of 3.35 ± 0.30 sessions a week in the aerobic group, and 17 subjects exercised an average of 3.39 ± 0.28 sessions a week in the resistance group. After completion of the training program, hepatic fat content was similarly reduced in both groups (P < 0.001). The mean relative reduction from baseline in the aerobic group was -10.3% (95% confidence interval -18.2 to -2.40) and the resistance group was -12.6% (-20.5 to -4.69). Liver steatosis (defined as controlled attenuation parameter >248 dB/m) disappeared in 9 (50%) of the aerobic group and in 9 (53%) of the resistance group. Whole-body and muscle insulin sensitivity indexes were improved, and waist circumference was reduced comparably in both exercise groups. The number of exercise sessions per week was correlated with the absolute reduction in hepatic fat content (r = 0.52; P = 0.001). Weekly exercise training ≥3 sessions substantially attenuates liver fat accumulation independent of weight loss. DISCUSSION Moderate-intensity aerobic training and resistance training with dietary modification are equally effective for reducing intrahepatic fat and improving underlying insulin resistance among patients with NAFLD.

Abstract
BACKGROUND Clinical care for type 2 diabetes has improved but remains suboptimal. Collaborative, team-based models that maximize skills of different disciplines may improve care for individuals with diabetes, but few have been tested using rigorous research designs. OBJECTIVE To investigate the efficacy of a registered dietitian nutritionist-led telemedicine program compared with that of a control group in terms of diabetes optimal care goals. DESIGN A randomized controlled trial in which participants were assigned to a control or intervention group. PARTICIPANTS/SETTING One hundred eighteen adults with type 2 diabetes (mean age, 60 years; 45% female) participated in the study between April 2016 and December 2017. Participants were recruited from separate primary care clinics in two rural Minnesota communities. INTERVENTION For those assigned to the intervention, registered dietitian nutritionists used a treatment protocol to initiate and titrate therapies for blood glucose, hypertension, and lipid levels in addition to providing medical nutrition therapy; telemedicine visits supplemented usual care. MAIN OUTCOME MEASURES Primary outcomes included composite and individual diabetes optimal care goals: hemoglobin A1c, blood pressure, not using tobacco, and taking a statin and aspirin (as appropriate). Secondary measures included physical activity, breakfast, fruits and vegetables, whole grains, body mass index, low-density lipoprotein, and medication adherence. STATISTICAL ANALYSIS Mixed-model regression was used to examine outcomes between baseline and 1-year follow-up. RESULTS A modest but significantly greater improvement in the number of diabetes optimal care measures met at follow-up was found in the intervention group (3.7 vs 3.2 in the control group [P=0.017]). Among individual measures, the intervention group had significantly greater medication use, with 2.5 and 2.2 higher odds (compared with the control group) of taking a statin [95% CI, 1.0 to 6.24]) and aspirin [95% CI, 0.90 to 5.19] as appropriate, respectively. CONCLUSIONS ENHANCED (diEtitiaNs Helping pAtieNts CarE for Diabetes) findings suggest that registered dietitian nutritionists following medication treatment protocols can effectively improve care for adults with type 2 diabetes and can serve an instrumental role as part of the health care team in providing evidence-based, patient-centered care.

Abstract
BACKGROUND Evidence from healthcare professionals suggest that consumer compliance to healthy diet and lifestyle changes is often poor. The present study investigated the effect of advice provided by a physician or dietitian on consumer adherence to these measures combined with consuming foods with added plant sterols (PS) with the aim of lowering low-density lipoprotein cholesterol (LDL-C). METHODS One hundred mildly-to-moderately hypercholesterolaemic individuals were enrolled into a parallel, randomised, placebo-controlled study. Dietitians (dietitian group; DG) advised 50 individuals in six weekly face-to-face behavioural therapy sessions, whereas the other 50 received standard advice from physicians (physician group, PG). Both groups consumed foods with added PS (three servings a day) for 6 weeks. Subsequently, all individuals were followed-up for another 6 weeks under real-life conditions. Blood lipids were measured at baseline and weeks 6 and 12 and 3-day diet diaries were taken at weeks 1, 6 and 12. RESULTS Individuals in the DG significantly improved their dietary habits, physical activity and increased PS intake compared to the PG. After 6 weeks, LDL-C decreased in both groups compared to baseline without any significant differences between groups. At week 12, LDL-C was further significantly improved only in the DG (P = 0.006) compared to week 6. Total cholesterol, LDL-C and triglycerides were significantly lower in the DG compared to the PG at week 12 after adjusting for levels at week 6 (P < 0.001, P < 0.001 and P = 0.009, respectively). CONCLUSIONS Although structured counselling by dietitians and common standard advice by physicians were equally effective with respect to improving blood cholesterol after 6 weeks, dietitians were more effective in the longer-term (i.e. 6 weeks after the end of the intervention period).

Abstract
OBJECTIVE To assess the effect of a nutrition education intervention included in the Home Care Program for caregivers to prevent the increasing risk of malnutrition of dependent patients at risk of malnutrition. DESIGN Randomized controlled multicenter trial of 6 months of duration and 12 months follow-up. SETTINGS 10 Primary Care Centers, Spain. PARTICIPANTS Patients enrolled in the Home Care Program between January 2010 and March 2012, who were dependent and at risk of malnutrition, older than 65, and had caregivers (n=190). INTERVENTION The nurses conducted initial educational intervention sessions for caregivers and then monitored at home every month for 6 months. MEASUREMENTS The nutritional status was assessed using the Mini Nutritional Assessment test (primary outcome), diet, anthropometry, and biochemical parameters (albumin, prealbumin, hemoglobin and cholesterol). Other descriptive and outcome measures were recorded: current medical history, Activities of daily living (Barthel test), cognitive state (Pfeiffer test), and mood status (Yesavage test). All the measures were recorded in a schedule of 0-6-12 months. RESULTS 173 individuals participated after exclusions (intervention n=101; control n=72). Mean age was 87.8±8.9years, 68.2% were women. Difference were found between the groups for Mini Nutritional Assessment test score change (repeated measures ANOVA, F=10.1; P<0.001), the intervention improved the Mini Nutritional Assessment test score of the participants in the intervention group. The egg consumption (F=4.1; P=0.018), protein intake (F=3.0; P=0.050), polyunsaturated fatty acid intake (F=5.3; P=0.006), folate (F=3.3; P=0.041) and vitamin E (F=6.4; P=0.002) showed significant group×time interactions. CONCLUSION A nutrition education intervention for caregivers halted the tendency of nutritional decline, and reduced the risk of malnutrition of older dependent patients.
