Alan M Nevill, Carlton B Cooke
PURPOSE: To compare the accuracy and goodness-of-fit of two competing models (linear versus allometric) when estimating V˙O2max (ml.kg.min) using non-exercise prediction models. METHODS: The two competing models were fitted to the V˙O2max (ml.kg.min) data taken from two previously published studies. Study 1 (the Allied Dunbar National Fitness Survey, ADNFS), recruited 1732 randomly selected healthy participants, aged 16 years and over, from thirty English parliamentary constituencies...

BACKGROUND: Hypothermia in neonatal intensive care unit patients is associated with morbidity. Perioperative normothermia is the standard of care. AIMS: We hypothesized that a quality improvement intervention (transport protocol, transport education, ongoing monitoring) would decrease the incidence of perioperative hypothermia. Secondarily, we hypothesized that patients undergoing surgery at a postmenstrual age of <37 weeks or at a weight of <1.5 kg would be at higher risk for perioperative hypothermia...

BACKGROUND: Hip fracture occurs predominantly in older people, many of whom are frail and undernourished. After hip fracture surgery and rehabilitation, most patients experience a decline in mobility and function. Anabolic steroids, the synthetic derivatives of the male hormone testosterone, have been used in combination with exercise to improve muscle mass and strength in athletes. They may have similar effects in older people who are recovering from hip fracture. OBJECTIVES: To examine the effects (primarily in terms of functional outcome and adverse events) of anabolic steroids after surgical treatment of hip fracture in older people...

Poor dispersal species represent conservative benchmarks for biodiversity management because they provide insights into ecological processes influenced by habitat fragmentation that are less evident in more dispersive organisms. Here we used the poorly dispersive and threatened river blackfish (Gadopsis marmoratus) as a surrogate indicator system for assessing the effects of fragmentation in highly modified river basins and for prioritizing basin-wide management strategies. We combined individual, population and landscape-based approaches to analyze genetic variation in samples spanning the distribution of the species in Australia's Murray-Darling Basin, one of the world's most degraded freshwater systems...

REVIEW
Ida-Johanne Jensen, Hanne K Mæhre
High seafood consumption has traditionally been linked to a reduced risk of cardiovascular diseases, mainly due to the lipid lowering effects of the long chained omega 3 fatty acids. However, fish and seafood are also excellent sources of good quality proteins and emerging documentation show that, upon digestion, these proteins are sources for bioactive peptides with documented favorable physiological effects such as antioxidative, antihypertensive and other cardioprotective effects. This documentation is mainly from in vitro studies, but also animal studies are arising...

Obesity affects the major metabolic and cellular processes involved in skeletal muscle contractility. Surprisingly, the effect of obesity on isolated skeletal muscle performance remains unresolved. The present study is the first to examine the muscle specific changes in contractility following dietary induced obesity using an isolated muscle work-loop (WL) model that more closely represents in vivo muscle performance. Following 16-week high calorific feeding, soleus (SOL), extensor digitorum longus (EDL), and diaphragm (DIA) were isolated from female (CD-1) mice and contractile performance compared against a lean control group...

The complexity of healthcare calls for interprofessional collaboration to improve and sustain the best outcomes for safe and high quality patient care. Historically, rehabilitation nursing has been an area that relies heavily on interprofessional relationships. Professionals from various disciplines often subscribe to different change management theories for continuous quality improvement. Through a case review, authors describe how a large, Midwestern, rehabilitation hospital used the crosswalk methodology to facilitate interprofessional collaboration and develop an intervention model for implementing and sustaining bedside shift reporting...

Order sets, a series of orders focused around a diagnosis, condition, or treatment, can reinforce best practice, help eliminate outdated practice, and provide clinical guidance. However, order sets require regular updates as evidence and care processes change. We undertook a quality improvement intervention applying lean methodology to create a systematic process for order set review and maintenance. Root cause analysis revealed challenges with unclear prioritization of requests, lack of coordination between teams, and lack of communication between producers and requestors of order sets...

Importance: Past studies have shown an association between metabolic syndrome and polyneuropathy, but the precise components that drive this association remain unclear. Objectives: To determine the prevalence of polyneuropathy stratified by glycemic status in well-characterized obese and lean participants and investigate the association of specific components of metabolic syndrome with polyneuropathy. Design, Setting, and Participants: We performed a cross-sectional, observational study from November 1, 2010, to December 31, 2014, in obese participants (body mass index [calculated as weight in kilograms divided by height in meters squared] of 35 or more with no comorbid conditions or 32 or more with at least 1 comorbid condition) from a weight management program and lean controls from a research website...

Loss of muscle mass and force with age leads to fall risk, mobility impairment, and reduced quality of life. This article shows that BDA-410, a calpain inhibitor, induced loss of body weight and fat but not lean mass or skeletal muscle proteins in a cohort of sedentary 23-month-old mice. Food and water intake and locomotor activity were not modified, whereas BDA-410 treatment decreased intramyocellular lipid and perigonadal fat, increased serum nonesterified fatty acids, and upregulated the genes mediating lipolysis and oxidation, lean phenotype, muscle contraction, muscle transcription regulation, and oxidative stress response...
