Rationale: Despite the importance of inflammation in chronic obstructive pulmonary disease (COPD), immune cell landscape lung tissue patients with mild-moderate has not been well characterized at single-cell and molecular level. Objectives: To define from COPD resolution. Methods: We performed transcriptomic, proteomic, T-cell receptor repertoire analyses on (n = 5, Global Initiative for Chronic Obstructive Lung Disease I or II), emphysema without airflow obstruction 5), end-stage 2),...
Abstract Background Due to the absence of a current and validated food frequency questionnaire (FFQ) for use in New Zealand adolescents, there is need develop one as cost-effective way assess adolescents’ patterns. This study aims examine test-retest reliability relative validity Adolescent FFQ (NZAFFQ) group intake adolescents aged 14 18 years. Methods A non-quantitative (without portion size), 72-item was developed pretested. Fifty-two participants (aged 14.9 ± 0.8 years) completed NZAFFQ...
Cardiovascular complications have emerged as a major concern for cancer patients. Many chemotherapy agents are cardiotoxic and some appear to also alter lipid profiles, although the mechanism this is unknown. We studied plasma levels in 12 breast patients throughout their chemotherapy. Patients received either four cycles of doxorubicin cyclophosphamide followed by weekly paclitaxel or three epirubicin, 5'-fluorouracil docetaxel. demonstrated significant reduction (0.32 mmol/L) high density...
Low energy availability (LEA) describes the disruption in normal physiological function existent when insufficient intake is combined with exercise. To conserve a range of endocrine adaptations occur, impairing health and athletic performance. The prevalence LEA has not been fully established especially among recreational exercisers. Determining exercisers at risk may help to maximize prevention, early diagnosis treatment. design this study was cross-sectional online survey. One-hundred nine...
Abstract Evidence suggests that omega‐3 fatty acid supplementation could reduce muscle soreness and maintain function following eccentric exercise‐induced damage. The aim of this applied field study was to investigate the effectiveness consuming a protein‐based supplement containing 1546 mg polyunsaturated (PUFA) (551 eicosapentaenoic (EPA) 551 docosahexaenoic (DHA)) twice daily (FO) compared placebo (P) on soreness, countermovement jump (CMJ) performance psychological well‐being in 20...
It is well documented that short sleep duration associated with excess body weight and poor food intake in children. has been suggested timing behaviour may also be an important predictor of other related behaviours, independent duration; however, there a lack research investigating these relationships. The present study investigated association diet physical activity levels 439 children aged 9-11 years old from New Zealand. Sleep data were collected using accelerometry, choice...
Previous research investigating the relationship between parents’ and children’s diets has focused on single foods or nutrients, not global diet, which may be more important for good health. The aim of study was to investigate parental diet quality child dietary patterns. A cross-sectional survey conducted in 17 primary schools Dunedin, New Zealand. Information food consumption related factors children their caregiver/parent were collected. Principal component analysis (PCA) used patterns...
As there is no population-specific, simple food-based diet index suitable for examination of quality in New Zealand (NZ) adolescents, a need to develop such tool. Therefore, this study aimed an adolescent-specific based on dietary information sourced from Food Questionnaire (FQ) and examine its validity relative four-day estimated food record (4DFR) obtained group adolescents aged 14 18 years. A NZ (NZDQI-A) was developed 'Adequacy' 'Variety' five groups reflecting the Nutrition Guidelines...
Abstract Objective To examine the association between cardiorespiratory fitness and dietary patterns in adolescents. Design Food choice was assessed using validated New Zealand Adolescent FFQ. Principal components analysis used to determine patterns. Trained research assistants measured participants’ height body mass. Cardiorespiratory a subset of participants multistage 20 m shuttle run. The level stage were recorded, corresponding VO 2max calculated. Differences mean according sex BMI t...

J Strength Cond Res 32(10): 2816-2824, 2018-It has been postulated that low availability (LEA) impacts bone health, concentrations, cardiovascular function. This study describes the lipid levels, profiles, nutrient intakes recreationally active adults at risk LEA compared with those not risk. Thirty-eight women who meet or exceed New Zealand guidelines for...
Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive disease which leads to significant morbidity and mortality from respiratory failure. The two drugs currently approved for clinical use slow the rate of decline in lung function but have not been shown halt progression or reverse established fibrosis. Thus, new therapeutic targets are needed. Endothelial injury resultant vascular permeability critical components response tissue present patients with IPF. However, it remains unclear...
This study examined changes in serum S100beta concentration, a peripheral marker of BBB permeability, response to exercise the heat with and without fluid ingestion.Eight physically active males completed up 90 min intermittent at power output corresponding 55% VO2peak warm environment (35 degrees C, 56% rh). Trials were (F trial) (NF replacement sweat losses. During trial, an aliquot plain water was ingested 15-min intervals match volume lost during previous period exercise.Exercise time...
Abstract Background Associations between food choice and body composition in previous studies of adolescents have been inconsistent. This may be due to the measures used, or these associations affected by dieting status adolescents. The objective this study was investigate association dietary patterns adolescents, determine if are moderated status. Methods Information on consumption current collected, using a web-based survey, 681 (mean age 15.8 (SD 0.9) years) from schools Otago, New...
Endurance events >10 hr are becoming increasingly popular but provide numerous physiological challenges, several of which can be attenuated with optimal nutritional intakes. Previous studies in ultraendurance races have reported large energy deficits during events. The authors therefore aimed to assess intakes relation performance among cyclists. This observational study included 18 cyclists a 384-km cycle race. At race registration each cyclist’s support crew was provided food diary for...
Sun safety and vitamin D status are important for prolonged health. They of particular interest to those working with athletes whom safe sun practices maybe limited. The aim this cross-sectional study was describe the attitudes elite New Zealand both exposure.110 outdoor volunteered participate in an interview a trained interviewer. interviewer asked questions on their Vitamin knowledge, regarding exposure as well concerns about skin cancer.Athletes were more concerned risk cancer (66%) than...
Sedentary time (ST) has been inconsistently associated with adiposity and cardiorespiratory fitness in children previous studies. We studied cross-sectional associations of ST, light physical activity (LPA), moderate-to-vigorous (MVPA) fat mass index (FMI) (estimated VO2max). Associations were evaluated without considering pattern ST by bout length. measured a wrist-worn accelerometer, FMI bioelectrical impedance, VO2max Pacer test 443 (51.2% girls, 10.2 ± 0.6 years). Isotemporal...
Research shows that cardiorespiratory (CRF) and muscular fitness in childhood are associated with a healthier cardiovascular profile adulthood. Identifying factors measures of could allow for strategies to optimize health throughout the lifecourse. The aim this study was examine association between dietary patterns both CRF 9⁻11-year-olds. In 398 children, were assessed using 20-m shuttle run test digital hand dynamometer, respectively. Dietary derived principal component analysis. Mixed...
