Sympathetic overdrive contributes to the derangement of glucose metabolism evident in clinical conditions, such as obesity, metabolic syndrome, type 2 diabetes, obstructive sleep apnea, and others. Targeting the sympathetic nervous system directly therefore appears as an attractive therapeutic approach to restore impaired glucose metabolism. Indeed, lifestyle interventions, including healthier ...

Physical activity has beneficial effects on the health of cancer survivors. We aimed to investigate accelerometer-assessed physical activity and sedentary time in cancer survivors, and describe activity profiles. Additionally, we identify demographic and clinical correlates of physical activity, sedentary time and activity profiles.Accelerometer, questionnaire and clinical data from eight studi...

The benefits of an active lifestyle after a breast cancer diagnosis are well recognized, but the majority of survivors are insufficiently active. The ACTIVATE Trial examined the efficacy of an intervention (use of the Garmin Vivofit 2 activity monitor coupled with a behavioral feedback and goal-setting session and 5 telephone-delivered health coaching sessions) to increase moderate to vigorous ...

This brief report examines the maintenance of moderate to vigorous physical activity (MVPA) and sedentary behavior changes approximately 12 weeks after the delivery of the ACTIVATE Trial primary intervention (use of the Garmin Vivofit 2 activity tracker coupled with a behavioral feedback and goal-setting session and 5 telephone-delivered health coaching sessions). We also examine the efficacy o...

Most previous studies on cardiovascular health (CVH) and incident type 2 diabetes (T2D) have used a single measure of CVH, and none have investigated the association with impaired fasting glucose (IFG). We examined the association between changes in CVH and incident T2D and IFG.Within the Whitehall II study, CVH was examined every 5 years from 1991 to 1993 until 2015 to 2016. Subjects with 0-2,...

This study aimed to quantify the sedative effects, detection rates and cardiovascular responses to xenon.On three occasions, participants breathed xenon (FXe 30%, for 20 min; FXe 50% for 5 min; FXe 70% for 2 min) in a non-blinded design. Sedation was monitored by a board certified anesthesiologist. During 70% xenon, participants were also verbally instructed to operate a manual value with time ...

Elevated plasma free fatty acids level has been implicated in the development of insulin resistance, inflammation, and endothelial dysfunction in diabetic and nondiabetic individuals. However, the underlying mechanisms still remain to be defined. Herein, we investigated the effect of palmitic acid (PA), the most abundant saturated fatty acid in the human body, on small-conductance Ca-activated ...

Candidalysin is a cytolytic peptide toxin secreted by Candida albicans hyphae and has significantly advanced our understanding of fungal pathogenesis. Candidalysin is critical for mucosal C albicans infections and is known to activate epithelial cells to induce downstream innate immune responses that are associated with protection or immunopathology during oral or vaginal infections. Furthermor...

Limited research has assessed the association between patterns of body mass index (BMI) change across adulthood and mortality. We aimed to identify groups of individuals who followed specific group-based BMI trajectories across adulthood, using weight collected on three occasions and recalled data from early adulthood, and to examine associations with all-cause and cause-specific mortality.Pros...

Lipid-lowering therapy (LLT) should be accompanied by dietary guidance for cardiovascular risk reduction; however, current evidence suggests sub-optimal dietary behaviors in those on LLT. We examined the associations between the dietary intake of key food groups (vegetables, fruit, cereal, protein, and dairy) and LLT use in Australian adults using quantile regression. We used data from the Aust...

It has been suggested that interleukin-6 (IL-6) produced by adipocytes in obesity leads to liver insulin resistance, although this hypothesis has never been definitively tested. Accordingly, we did so by generating adipocyte specific IL-6 deficient (AdipoIL-6) mice and studying them in the context of diet-induced and genetic obesity.-/-Mice carrying 2 floxed alleles of IL-6 (C57Bl/6J) were cros...

The established view is that vibrotactile stimuli evoke two qualitatively distinctive cutaneous sensations, flutter (frequencies < 60 Hz) and vibratory hum (frequencies > 60 Hz), subserved by two distinct receptor types (Meissner's and Pacinian corpuscle, respectively), which may engage different neural processing pathways or channels and fulfil quite different biological roles. In psychologica...

Background Population densities of many cities are increasing rapidly, with the potential for impacts on cardiovascular health. This longitudinal study examined the potential impact of population-density increases in urban areas (urban densification) on cardiovascular risk markers among Australian adults. Methods and Results Data were from the Australian Diabetes, Obesity and Lifestyle Study, i...

Myocardial infarction (MI) is a leading cause of mortality and morbidity worldwide and new treatment strategies are highly sought-after. Paradoxically, reperfusion of the ischemic myocardium, as achieved with early percutaneous intervention, results in substantial damage to the heart (ischemia/reperfusion injury) caused by cell death due to aggravated inflammatory and oxidative stress responses...

The impact of introducing new classes of glucose-lowering medication (GLM) on diabetes management remains unclear, especially outside North America and Western Europe. Therefore, we aimed to analyse trends in glycaemic control and the usage of new and old GLMs in people with type 2 diabetes from 2006 to 2015.Summary data from clinical services from nine countries outside North America and Weste...

HDL-mediated cholesterol efflux capacity (HDL-CEC) is a functional attribute that may have a protective role in atherogenesis. However, the estimation of HDL-CEC is based on in vitro cell assays that are laborious and hamper large-scale phenotyping.Here, we present a cost-effective high-throughput nuclear magnetic resonance (NMR) spectroscopy method to estimate HDL-CEC directly from serum. We a...

Chronic overconsumption of sugar-sweetened beverages (SSBs) is associated with unfavourable health effects, including promotion of obesity. However, the acute effects of consuming SSBs on glucose and lipid metabolism remain to be characterized in a real-world, post-prandial context of prolonged sitting. We quantified the acute effects of between-meal SSB consumption compared with water, on gluc...

Reducing hyperglycemia while avoiding hypoglycemia is the key clinical goal in managing people with type 1 diabetes. Insulin delivery techniques and regimens are constantly evolving to achieve these goals. At present, use of multiple daily injections (MDI) is the standard of care, but there is increasing interest in continuous subcutaneous insulin infusion (CSII). There is a deficit of studies ...
