Abstract	Objective: To investigate the feasibility of progressive resistance training for people with Prader-Willi syndrome (PWS), who have muscle weakness and very low muscle mass. Design: Randomised controlled trial with concealed allocation, assessor blinding and intention-to-treat analysis. Setting: Community gymnasium. Participants: Sixteen participants with PWS (eight female; mean age 25 years) were randomly assigned with 1:1 allocation to an experimental (n=8) or control group (n=8). Intervention: Progressive resistance training was performed twice a week for 10 weeks. The training was supervised one-to-one by a physiotherapist and comprised seven exercises. The control group continued their usual activities and were offered the training after follow-up assessment. Main outcome measures: Three domains of feasibility were evaluated: implementation (attendance and adherence), practicality (safety) and limited efficacy testing. Muscle strength (one repetition maximum for chest and leg press), physical function (box stacking test, timed stairs climb), muscle composition (US) and body composition (whole-body DXA scan) were measured before and after the intervention. Results: Participants attended 92% of scheduled sessions and adhered by progressing their training resistance by 82% (range 60-140%). There was one unexpected serious adverse event unrelated to the intervention and several non-serious expected adverse events related to the intervention. Estimates of standardised mean differences indicated moderate to large effects in favour of the experimental group for arm (0.92, 95%CI -0.11 to 1.95) and leg strength (0.78, 95%CI -0.27 to 1.83). The effect was uncertain for secondary outcomes. Conclusions: There is preliminary evidence showing progressive resistance training is feasible for people with Prader-Willi syndrome and may increase muscle strength.

Abstract	Background: Dietary intake of pregnant women do not appear to meet the dietary recommendations. Nutrition knowledge and practices of pregnant women and their antenatal care clinicians are factors that may be influential on dietary intakes of pregnant women. Aim: To assess and compare pregnancy nutrition recommendation knowledge and to explore how nutrition knowledge impacts on food choices in pregnant women and nutrition education practices of antenatal care providers. Methods: An explanatory sequential research mixed methods study design was applied. All participants were recruited from a metropolitan maternity hospital in Melbourne, Australia. The first phase assessed pregnancy nutrition knowledge and sources of nutrition information using a questionnaire (n=202) then followed semi-structured interviews with women and clinicians (n=31). Findings: The clinicians obtained significantly higher nutrition scores than compared to women, however, nutrition knowledge gaps were highlighted for both women and clinicians. Women reported receiving limited nutrition advice, a reflection of the clinicians reporting they provided limited nutrition advice. Conclusion: A key challenge for women adhering to dietary recommendations was having inadequate knowledge of the dietary recommendations and receiving limited information from their care providers. Similarly, as well as time constraints, limited nutrition knowledge and a lack of nutrition training impacted on the capacity of clinicians to provide adequate nutrition education.

Abstract	: Hypertension is a major risk factor for cardiovascular disease, affecting 1 billion people worldwide. Literature suggests some herbs and spices have cardiovascular benefits, such as decreasing blood pressure; yet evidence is inconsistent. This article reviewed randomized controlled trials investigating effects of herbs and spices on blood pressure in normotensive, pre-hypertensive and hypertensive participants. Ovid Medline, Embase, Biological abstracts, CINAHL and Cochrane Collaboration were systematically searched. After inclusion and exclusion criteria were applied, nine articles were included for analysis. Overall, three of the nine studies reported statistically significant results, including one of the two studies on hypertensive participants and two of the six studies on pre-hypertensive participants. The remaining study was conducted on normotensive participants and reported no change in blood pressure. There is evidence to suggest certain herbs and spices can reduce blood pressure in a hypertensive and pre-hypertensive population and may not induce hypotension in a normotensive population.

Abstract	Objectives This study explored nutrition knowledge of pregnant women, and how it correlated with participant characteristics, their main sources of information and changes to their diet since becoming pregnant. Methods Pregnant women residing in Australia accessing pregnancy forums on the internet were invited to complete a web-based questionnaire on general nutrition and pregnancy-specific nutrition guidelines. Results Of the 165 eligible questionnaire responses, 114 were complete and included in the analysis. Pregnancy nutrition knowledge was associated with education (r s = 0.21, p < 0.05) and income (r s = 0.21, p < 0.05). Only 2 % of pregnant women achieved nutrition knowledge scores over 80 %. Few women received nutrition advice during their pregnancy, of which most were advised by their doctor. Dietary changes adopted since becoming pregnant included consuming more fruit, vegetables, dairy and high fibre foods. Conclusions for Practice Pregnant women in this study had limited knowledge of the dietary guidelines for healthy eating during pregnancy. Furthermore, nutrition counselling in maternity care appears to be infrequent. One approach to optimising maternal diets and subsequently preventing adverse health outcomes is to enhance their knowledge of the pregnancy nutrition guidelines through the provision of nutritional counselling. Furthermore, research exploring the access and use of nutrition resources, and nutrition advice provided to pregnant women is recommended to understand how knowledge impacts on dietary behaviour.

Abstract	The association between intestinal permeability (IP) and body composition remains unclear. The gold standard differential sugar-absorption test is arduous to complete, with zonulin being increasingly used as an independent biomarker of IP. This pilot study aimed to explore the association between small IP, zonulin concentrations, and body composition in healthy adults. The urinary lactulose-rhamnose ratio was used to measure small IP. Serum zonulin, lipopolysaccharide (LPS) and high-sensitivity C-reactive protein (hs-CRP) were analyzed in serum. Body composition was measured using dual-energy X-ray absorptiometry and anthropometric measurements were collected. In total, 34 participants were included (12 males, median age 28 years, body mass index 24 kg/m², waist circumference 77cm). No correlation was observed between the lactulose-rhamnose ratio and zonulin (r = -.016, P = .929). The lactulose-rhamnose ratio displayed a strong positive correlation with LPS (n 20, r = .536, P = .018) but did not correlate with body composition measures. Conversely, zonulin displayed a moderate positive correlation with waist circumference (r = .437, P = .042) in female participants and hs-CRP (r = .485, P = .004) in all participants. These findings raise important considerations for the measurement of small IP, warranting exploration in larger powered studies that address the limitations of the present study.

Abstract	Background: Quinoa (Chenopodium quinoa) is a pseudo-cereal originally cultivated in the Andean region. The popularity of its seeds has increased in recent years due to the claims of health benefits and superfood qualities. Studies to date on the health benefits of quinoa have been restricted to animal models, and the results provide weak to moderate evidence to support improved plasma lipid profiles. Clinical trials in humans to examine the claims of health benefits of quinoa are limited to a few prospective studies and one randomized trial carried out in postmenopausal women. To our knowledge, no studies have been conducted in the general population. Objective: The objective of this randomized clinical trial was to investigate the effect of different quinoa doses (25 and 50 g/d) on body composition, serum lipids and hormones, and nutrient intakes in overweight and obese humans. Methods: This was a dose-response randomized, controlled, single-blind trial with a parallel design (1 control and 2 treatment groups) that compared the effect of 25 and 50 g quinoa/d in 50 overweight and obese participants over a 12-wk intervention period. Results: Body composition, nutrient intake, and total, LDL, and HDL cholesterol were not significantly altered by quinoa consumption (P > 0.05). Mean serum triglyceride (TG) concentration was reduced significantly in the 50-g quinoa group from 1.14 to 0.72 mmol/L at 12 wk (P < 0.05). The prevalence of metabolic syndrome (MetS) was also reduced in this group by 70%. No significant changes in TGs were observed in the control and 25-g quinoa groups. The prevalence of MetS was reduced by 40% (from n = 7 at baseline to n = 4 at 12 wk) in the 25-g group. Conclusions: The consumption of 50 g quinoa/d lowers serum TGs in overweight and obese participants and reduces the prevalence of MetS. This trial was registered at clinicaltrials.gov as UTN U1111-1175-470.

Abstract	Background: Increased intestinal permeability (IP) is associated with sepsis in the intensive care unit (ICU). This study aimed to pilot a sensitive multisugar test to measure IP in the nonfasted state. Methods: Critically ill, mechanically ventilated adults were recruited from 2 ICUs in Australia. Measurements were completed within 3 days of admission using a multisugar test measuring gastroduodenal (sucrose recovery), small-bowel (lactulose-rhamnose [L-R] and lactulose-mannitol [L-M] ratios), and whole-gut permeability (sucralose-erythritol ratio) in 24-hour urine samples. Urinary sugar concentrations were compared at baseline and after sugar ingestion, and IP sugar recoveries and ratios were explored in relation to known confounders, including renal function. Results: Twenty-one critically ill patients (12 males; median, 57 years) participated. Group median concentrations of all sugars were higher following sugar administration; however, sucrose and mannitol increases were not statistically significant. Within individual patients, sucrose and mannitol concentrations were higher in baseline than after sugar ingestion in 9 (43%) and 4 (19%) patients, respectively. Patients with impaired (n = 9) vs normal (n = 12) renal function had a higher L-R ratio (median, 0.130 vs 0.047; P = .003), lower rhamnose recovery (median, 15% vs 24%; P = .007), and no difference in lactulose recovery. Conclusion: Small-bowel and whole-gut permeability measurements are possible to complete in the nonfasted state, whereas gastroduodenal permeability could not be measured reliably. For small-bowel IP measurements, the L-R ratio is preferred over the L-M ratio. Alterations in renal function may reduce the reliability of the multisugar IP test, warranting further exploration.

Abstract	Background & aims: The Mediterranean diet (MedDiet) is recognised to reduce risk of coronary heart disease (CHD), in part, via its anti-inflammatory and antioxidant properties, which may be mediated via effects on body fat distribution. Diet efficacy via these mechanisms is however unclear in patients with diagnosed CHD. This study aimed to determine: (1) the effect of ad libitum MedDiet versus low-fat diet intervention on adiposity, anti-inflammatory marker adiponectin, oxidative stress marker malondialdehyde (MDA) and traditional CVD risk markers, and (2) whether improvement in MedDiet adherence score in the pooled cohort was associated with these risk markers, in a pilot cohort of Australian patients post coronary event. Methods: Participants (62 ± 9 years, 83% male) were randomised to 6-month ad libitum MedDiet (n = 34) or low-fat diet (n = 31). Pre- and post-intervention, dietary adherence, anthropometry, body composition (Dual-energy X-ray Absorptiometry) and venepuncture measures were conducted. Results: The MedDiet group reduced subcutaneous adipose tissue (SAT) area compared to the low-fat diet group (12.5 cm Conclusions: Adherence to 6-month ad libitum MedDiet reduced subcutaneous fat and waist circumference which discounts the misconception that this healthy but high fat diet leads to body fat gain. The effect of MedDiet on body fat distribution and consequent anti-inflammatory and antioxidant effects, as well as need for medications, in patients with CHD warrants exploration in larger studies. Clinically significant effects on these markers may require adjunct exercise and/or caloric restriction. Trial registration: ACTRN12616000156482.

Abstract	The Mediterranean diet (MedDiet) is recognised to reduce risk of coronary heart disease (CHD), in part, via its anti-inflammatory and antioxidant properties, which may be mediated via effects on body fat distribution. Diet efficacy via these mechanisms is however unclear in patients with diagnosed CHD. This study aimed to determine: (1) the effect of ad libitum MedDiet versus low-fat diet intervention on adiposity, anti-inflammatory marker adiponectin, oxidative stress marker malondialdehyde (MDA) and traditional CVD risk markers, and (2) whether improvement in MedDiet adherence score in the pooled cohort was associated with these risk markers, in a pilot cohort of Australian patients post coronary event.Participants (62 ± 9 years, 83% male) were randomised to 6-month ad libitum MedDiet (n = 34) or low-fat diet (n = 31). Pre- and post-intervention, dietary adherence, anthropometry, body composition (Dual-energy X-ray Absorptiometry) and venepuncture measures were conducted.The MedDiet group reduced subcutaneous adipose tissue (SAT) area compared to the low-fat diet group (12.5 cm2 more, p = 0.04) but not visceral adipose tissue or other body composition measures. In the pooled cohort, participants with greatest improvement in MedDiet adherence score had significantly lower waist circumference (−2.81 cm, p = 0.01) and SAT area (−27.1 cm2, p = 0.04) compared to participants with no improvement in score at 6-months. There were no changes in adiponectin, MDA or other risk markers in the MedDiet compared to low-fat diet group, and no differences in 6-month levels between categories of improvement in MedDiet score (p > 0.05). Within the MedDiet group only, the proportion of participants taking beta-blocker medication reduced from baseline to 6-months (71% vs. 56%, p-trend = 0.007).Adherence to 6-month ad libitum MedDiet reduced subcutaneous fat and waist circumference which discounts the misconception that this healthy but high fat diet leads to body fat gain. The effect of MedDiet on body fat distribution and consequent anti-inflammatory and antioxidant effects, as well as need for medications, in patients with CHD warrants exploration in larger studies. Clinically significant effects on these markers may require adjunct exercise and/or caloric restriction.ACTRN12616000156482.
