INTRODUCTION: Diabetes mellitus is common in primary care, yet little has been reported of its primary care prevalence or the clinical characteristics of patients with Type 2 diabetes mellitus (T2DM). AIM: To determine the prevalence of diabetes mellitus and clinical characteristics of diabetes patients in primary care in the Waikato region. METHODS: Primary care data were extracted from the electronic records of 15 general practices for patients aged >20 years with current diabetes mellitus at 20 June 2017. Diabetes mellitus was defined as having a glycated haemoglobin (HbA1c) of ≥50 mmol/mol (6.7%) or having being dispensed two or more anti-diabetic medications in the previous 12 months. Additional data collected included patients' ethnicity, age, sex and years since diagnosis. RESULTS: The overall prevalence of diabetes mellitus was 5.7% and was higher for Māori (8.6%), Asian (7.0%) and Pacific peoples (9.1%) than Europeans (5.0%; all P < 0.001). For patients with T2DM for whom current diabetes annual review data were available (n = 2227) the mean body mass index (BMI) was 32.8 ± 0.2 kg/m2, but BMI was higher in Māori, younger patients, females and patients diagnosed <2 years previously (all P < 0.001). Similarly, HbA1c levels were highest in Māori and younger patients (both P < 0.001), with 40% of patients overall having a HbA1c of ≤53 mmol/mol (7.0%). Approximately 70% of all patients had at least one measure of hypertension (systolic ≥130 or diastolic ≥80 mmHg), or dyslipidaemia. More than 85% of patients had completed a recent retinal screen and foot check. DISCUSSION: We found that management of T2DM was suboptimal, with measures for many patients not meeting clinical targets. Support should be provided to improve weight and glycaemic management, particularly for Māori, females and younger patients. [ABSTRACT FROM AUTHOR]

Purpose: While several studies have documented isokinetic knee strength in junior and senior rugby league players, investigations of isokinetic knee and hip strength in professional rugby union players are limited. The purpose of this study was to provide lower-extremity strength profiles and compare isokinetic knee and hip strength of professional rugby league and rugby union players. Participants: 32 professional rugby league and 25 professional rugby union players. Methods: Cross-sectional analysis. Isokinetic dynamometry was used to evaluate peak torque and strength ratios of the dominant and nondominant legs during seated knee-extension/ flexion and supine hip-extension/flexion actions at 60°/s. Results: Forwards from both codes were taller and heavier and had a higher body-mass index than the backs of each code. Rugby union forwards produced significantly (P < .05) greater peak torque during knee flexion in the dominant and nondominant legs (ES = 1.81 and 2.02) compared with rugby league forwards. Rugby league backs produced significantly greater hip-extension peak torque in the dominant and nondominant legs (ES = 0.83 and 0.77) compared with rugby union backs. There were no significant differences in hamstring-to-quadriceps ratios between code, position, or leg. Rugby union forwards and backs produced significantly greater knee-flexion-to-hip-extension ratios in the dominant and nondominant legs (ES = 1.49-2.26) than rugby union players. Conclusions: It seems that the joint torque profiles of players from rugby league and union codes differ, which may be attributed to the different demands of each code. [ABSTRACT FROM AUTHOR]

Aim: Total gastrectomy and Ivor Lewis oesophagectomy procedures are the mainstay of upper gastrointestinal cancer management. Maintenance of adequate nutritional intake is essential for positive patient outcomes. Although numerous nutritional support options exist, clear evidence‐based guidelines on the optimal means and duration of nutritional support are lacking. The aim of this study is to establish preliminary data on the current perioperative nutritional practices of upper gastrointestinal surgeons performing these procedures across Australia and New Zealand. It is hoped this will help provide the platform for future research towards establishing evidence‐based guidelines in upper gastrointestinal surgery. Methods: A questionnaire exploring the nutritional practices and considerations of surgeons was developed and emailed to the members of the Australia & New Zealand Gastric & Oesophageal Surgery Association. Results: A total of 27.4% of Australia & New Zealand Gastric & Oesophageal Surgery Association members completed the questionnaire. Surgeons reported inserting a jejunostomy feeding tube intraoperatively in Ivor Lewis oesophagectomy procedures 80–100% of the time, compared to only 20–39% of the time in total gastrectomy procedures. For both procedures, surgeons often refer their patients to a dietitian preoperatively, and always postoperatively. Preoperative immune‐enhancing nutrition is rarely administered. Patient age and BMI are deemed to be of low importance when determining the means of nutritional support. Conclusions: This study has demonstrated the current nutritional practices employed in Australia and New Zealand for patients undergoing major upper gastrointestinal surgery. Questions remain regarding the noted differences between procedures as well as the optimal means and duration of perioperative nutritional support. [ABSTRACT FROM AUTHOR]

Aim: To establish the prevalence of nutrition risk and associated risk factors among adults of advanced age newly admitted to hospital. Methods: A cross‐sectional study was undertaken in adults aged over 85 years admitted to one of two hospital wards in Auckland within the previous 5 days. An interviewer‐administered questionnaire was used to establish participant's socio‐demographic and health characteristics. Markers of body composition and muscle strength were collected. Nutrition risk was assessed using the Mini Nutritional Assessment‐Short Form (MNA‐SF), dysphagia risk using the 10‐Item Eating Assessment Tool (EAT‐10) and level of cognition using the Montreal Cognitive Assessment. Results: A total of 88 participants with a mean age of 90.0 ± 3.7 years completed the assessments. A third (28.4%) of the participants were categorised by the MNA‐SF as malnourished and 43.2% were classified at risk of malnutrition. A third (29.5%) were at risk of dysphagia as assessed by EAT‐10. Malnourished participants were more likely to be at risk of dysphagia (P = 0.015). The MNA‐SF score was positively correlated with body mass index (r = 0.484, P < 0.001) and grip strength (r = 0.250, P = 0.026) and negatively correlated with risk of dysphagia (r = −0.383, P < 0.001). Conclusions: Among newly hospitalised adults of advanced age, over two thirds were malnourished or at risk of malnutrition, and a third were at risk of dysphagia. Nutrition risk was positively correlated with low BMI and grip strength and negatively correlated with dysphagia risk. Findings highlight the importance of screening for dysphagia risk, especially in those identified to be malnourished or at nutrition risk. [ABSTRACT FROM AUTHOR]

Purpose: To measure the iodine status and iodine intake of New Zealand adults 18-64 years of age following mandatory fortification of bread with iodine. Methods: A cross-sectional survey of NZ adults living in Dunedin and Wellington during February-November 2012. Three hundred and one men and women aged 18-64 years randomly selected from the New Zealand Electoral Roll completed a 24-h urine collection, a demographic and iodine-specific food frequency questionnaire (FFQ), and had height and weight measured. Urine collections were analysed for iodine and reported as median urinary iodine concentration (UIC) µg/L and median urinary iodine excretion (UIE) µg/day. The FFQ was used to estimate iodine intake with and without discretionary iodised salt use. Results: The median UIC for all adults was 73 µg/L, indicative of mild iodine deficiency. The mean urinary volume was 2.0 L. As an estimate of iodine intake, the median UIE was 127 µg/day. Estimated iodine intake, using the FFQ which included discretionary iodised salt use, was 132 µg/day. Iodine intakes were associated with UIC ( P = 0.040) and UIE ( P = 0.003), but not with bread iodine intake and iodised salt use. Conclusion: Using the WHO/UNICEF/ICCIDD target for iodine sufficiency (a UIC of >100 µg/L) based on school-aged children with a mean urinary volume of 1.0 L, the iodine status of NZ adults does not reach adequate levels (73 µg/L). A more realistic parameter in a population with a higher urinary volume excretion (2.0 L) is the UIE. A median UIE of 127 µg/day suggests that the iodine status of NZ adults is now likely to be adequate. [ABSTRACT FROM AUTHOR]

Summary: Background: There is a relationship between childhood obesity and area‐level deprivation. While the New Zealand Index of Deprivation (NZDep) has been used widely in research for the past 20 years, the Index of Multiple Deprivation (IMD) was released in 2017. This study aims to investigate the association between deprivation and childhood obesity in New Zealand and compare measures of deprivation. Methods: Data from 316 794 4‐year‐olds in New Zealand undertaking the B4 School Check in 2010 to 2016, a national health and development screen, were analysed. Multilevel logistic regression models assessed the relationship between area‐level deprivation and individual‐level child obesity. Models were adjusted for age, sex, immigration status, ethnicity, and year. Deprivation was measured using the census‐based NZDep2013 (deciles) and the administrative data‐based IMD (deciles). The seven domains of the IMD were also considered. Results: The relationship between deprivation and obesity was very similar for the IMD and NZDep2013, point estimates were near identical, and confidence intervals overlapped substantially. Higher levels of deprivation were associated with a higher prevalence of child obesity. The relationship between deprivation and child obesity varied considerably across IMD domains. The education domain had the strongest association with child obesity and had an association with child obesity independent of the other domains of deprivation. Conclusion: Overall, there was little difference between the NZDep and IMD. However, the IMD's domains and IMD‐1 approach reveal more nuanced understandings of the deprivation‐obesity gradient, including the importance of area‐level education deprivation for predicting child obesity rates.
