Bringing a Network-Oriented Approach to Domestic Violence Services: A Focus Group Exploration of Promising Practices.

Despite powerful evidence that informal social support contributes to survivors' safety and well-being, mainstream domestic violence (DV) programs have not developed comprehensive models for helping isolated survivors re-engage with these networks. Although many advocates use network-oriented strategies informally, they often do so without resources, funding, or training. This qualitative focus group study explored advocates' use and perceptions of network-oriented strategies.

Diurnal patterns of objectively measured physical activity and sedentary behaviour in older men.

Background: Physical activity (PA) levels among older adults are generally low and sedentary behaviour (SB) very common; increasing PA and reducing SB levels could have appreciable health benefits. Quantifying PA and SB patterns through the day could help in defining strategies for change. We examined within day variations in PA and SB and whether these varied by demographic factors and health status.

Evaluation of a Mobile Phone Image-Based Dietary Assessment Method in Adults with Type 2 Diabetes.

Image-based dietary records have limited evidence evaluating their performance and use among adults with a chronic disease. This study evaluated the performance of a 3-day mobile phone image-based dietary record, the Nutricam Dietary Assessment Method (NuDAM), in adults with type 2 diabetes mellitus (T2DM). Criterion validity was determined by comparing energy intake (EI) with total energy expenditure (TEE) measured by the doubly-labelled water technique.

A mixed-methods research approach to the review of competency standards for orthotist/prosthetists in Australia.

Aim: The requirement for an allied health workforce is expanding as the global burden of disease increases internationally. To safely meet the demand for an expanded workforce of orthotist/prosthetists in Australia, competency based standards, which are up-to-date and evidence-based, are required. The aims of this study were to determine the minimum level for entry into the orthotic/prosthetic profession; to develop entry level competency standards for the profession; and to validate the developed entry-level competency standards within the profession nationally, using an evidence-based approach.

Removable cast chrome cobalt retainers for extended or indefinite period clinical use.

Patients are frequently being asked to wear orthodontic retainers for as long as they want their teeth to remain in the post-treatment position. Fixed retainers, which are placed on the lingual surface of anterior teeth only, have the advantage of minimal compliance issues but are not without their problems related to wire fracture, adhesive failure and potential gingival or periodontal disease. Plastic retainers, although associated with relatively good aesthetics and compliance, have limitations related to their physical and mechanical properties.

A randomised controlled trial using the Epidrum for labour epidurals.

The aim of our study was to determine if using the Epidrum to site epidurals improves success and reduces morbidity. Three hundred parturients requesting epidural analgesia for labour were enrolled. 150 subjects had their epidural sited using Epidrum and 150 using standard technique.

Physical Activity and Falls in Older Men: The Critical Role of Mobility Limitations.

Background: Physical activity (PA) has many health benefits but may increase falls risk among older adults. We study how objectively measured habitual daily PA is related to falls by exploring the modifying effect of mobility limitations and the mediating roles of fitness and lower-limb strength.

Methods: One thousand six hundred fifty-five (53%) of 3137 surviving participants (men age 71-91 yr) in an ongoing UK-population-based cohort study wore an ActiGraph GT3x accelerometer over the hip for 1 wk in 2010-2012 to measure PA (exposure) and reported demographic and health status, including mobility limitations.

A phase 2 study on the treatment of hyperkalemia in patients with chronic kidney disease suggests that the selective potassium trap, ZS-9, is safe and efficient.

Hyperkalemia contributes to significant mortality and limits the use of cardioprotective and renoprotective renin-angiotensin-aldosterone blockers. Current therapies are poorly tolerated and not always effective. Here we conducted a phase 2 randomized, double-blind, placebo-controlled dose-escalation study to assess safety and efficacy of ZS-9.

Deficits in sentence expression in amyotrophic lateral sclerosis.

Quantitative examinations of speech production in amyotrophic lateral sclerosis (ALS) are rare. To identify language features minimally confounded by a motor disorder, we investigated linguistic and motor sources of impaired sentence expression in ALS, and we related deficits to gray matter (GM) and white matter (WM) MRI abnormalities. We analyzed a semi-structured speech sample in 26 ALS patients and 19 healthy seniors for motor- and language-related deficits.

Improved nutritional status is related to improved quality of life in Parkinson's disease.

Background: Quality of life is poorer in Parkinson's disease than in other conditions and in the general population without Parkinson's disease. Malnutrition also results in poorer quality of life. This study aimed at determining the relationship between quality of life and nutritional status.

How are falls and fear of falling associated with objectively measured physical activity in a cohort of community-dwelling older men?

Background: Falls affect approximately one third of community-dwelling older adults each year and have serious health and social consequences. Fear of falling (FOF) (lack of confidence in maintaining balance during normal activities) affects many older adults, irrespective of whether they have actually experienced falls. Both falls and fear of falls may result in restrictions of physical activity, which in turn have health consequences.

Xenon decreases cell migration and secretion of a pro-angiogenesis factor in breast adenocarcinoma cells: comparison with sevoflurane.

Background: While volatile agents have been implicated in metastasis-enhancing effects on cancer cells, the effects of xenon are unknown. We investigated xenon- and sevoflurane-mediated effects on migration and expression of angiogenesis biomarkers in human breast adenocarcinoma cells.

Methods: MDA-MB-231 and MCF-7 cells were exposed to xenon 70% with O2 25%, CO2 5%; control gas containing O2 25%, CO2 5%, N2 70%; or sevoflurane 2.

Narrative discourse deficits in amyotrophic lateral sclerosis.

Objective: We examined narrative discourse in amyotrophic lateral sclerosis (ALS) to assess the role of executive functioning in support of language and the neuroanatomical basis for such support.

Methods: We analyzed a semistructured speech sample in 26 patients with ALS and 19 healthy seniors for narrative discourse features of coherence. Regression analyses related a measure of discourse coherence ("local connectedness") to gray matter atrophy and reduced white matter fractional anisotropy.

Trajectories of objectively measured physical activity in free-living older men.

Background: The steep decline in physical activity (PA) among the oldest old is not well understood; there is little information about the patterns of change in PA and sedentary behaviour (SB) in older people. Longitudinal data on objectively measured PA data can give insights about how PA and SB change with age.

Methods: Men age 70-90 yr, from a United Kingdom population-based cohort wore a GT3X accelerometer over the hip annually on up to three occasions (56%, 50%, and 51% response rates) spanning 2 yr.

Negative selection by apoptosis enriches progenitors in naïve and expanded human umbilical cord blood grafts.

The influence of TNF-α and Fas-ligand (FasL) on viability and function was evaluated in fresh- and expanded-umbilical cord blood (UCB) cells. CD34(+) progenitors and T cells display outstanding survival, whereas ~30% and >50% B lymphocytes and myeloid cells undergo spontaneous apoptosis within 24 and 48 h, respectively. Although the impact of exposure to toxic doses of FasL and TNF-α was undetectable in measurements of apoptosis; removal of dead cells after 2 days of incubation with the ligands revealed a twofold increase in frequency of colony-forming cells (CFU).

Adherence to physical activity guidelines in older adults, using objectively measured physical activity in a population-based study.

Background: Physical activity (PA) levels in older adults decline with age. The prevalence and correlates of adherence to current UK PA guidelines in older adults has not been studied using objectively measured PA, which can examine precisely whether PA is carried out in bouts of specified length and intensity.

Methods: Free living men and women aged 70-93 years from 25 towns in the United Kingdom, participating in parallel on-going population based cohort studies were invited (by post) to wear a GT3x accelerometer over the hip for one week in 2010-12.

Serum 25-hydroxy vitamin D concentrations are more deficient/insufficient in peritoneal dialysis than haemodialysis patients in a sunny climate.

Background: Research has identified associations between serum 25(OH)D and a range of clinical outcomes in chronic kidney disease and wider populations. The present study aimed to investigate vitamin D deficiency/insufficiency in dialysis patients and the relationship with vitamin D intake and sun exposure.

Methods: A cross-sectional study was used.

uPARAP function in cutaneous wound repair.

Optimal skin wound healing relies on tight balance between collagen synthesis and degradation in new tissue formation and remodeling phases. The endocytic receptor uPARAP regulates collagen uptake and intracellular degradation. In this study we examined cutaneous wound repair response of uPARAP null (uPARAP-/-) mice.

Stable activity of diabetogenic cells with age in NOD mice: dynamics of reconstitution and adoptive diabetes transfer in immunocompromised mice.

The non-obese diabetic (NOD) mouse is a prevalent disease model of type 1 diabetes. Immune aberrations that cause and propagate autoimmune insulitis in these mice are being continually debated, with evidence supporting both dominance of effector cells and insufficiency of suppressor mechanisms. In this study we assessed the behaviour of NOD lymphocytes under extreme expansion conditions using adoptive transfer into immunocompromised NOD.

Apoptotic signaling through Fas and TNF receptors ameliorates GVHD in mobilized peripheral blood grafts.

Mobilized peripheral blood (mPB) is a prevalent source of hematopoietic progenitors for transplantation; however, allogeneic and haploidentical transplants are often accompanied by severe GVHD. Following the observation that murine GVHD is ameliorated by pretransplant donor cell exposure to Fas-ligand (FasL) without host-specific sensitization, we assessed the susceptibility of mPB cells to spontaneous and receptor-induced apoptosis as a possible approach to GVHD prophylaxis. Short incubation for 4 h resulted in spontaneous apoptosis of 50% of the T and B lymphocytes and 60% myeloid cells.

Nutrition prescription to achieve positive outcomes in chronic kidney disease: a systematic review.

In Chronic Kidney Disease (CKD), management of diet is important in prevention of disease progression and symptom management, however evidence on nutrition prescription is limited. Recent international CKD guidelines and literature was reviewed to address the following question "What is the appropriate nutrition prescription to achieve positive outcomes in adult patients with chronic kidney disease?" Databases included in the search were Medline and CINAHL using EBSCOhost search engine, Embase and the Cochrane Database of Systematic Reviews published from 2000 to 2009. International guidelines pertaining to nutrition prescription in CKD were also reviewed from 2000 to 2013.

Potential role of WSB1 isoforms in growth and survival of neuroblastoma cells.

Background: WD repeat and SOCS box containing protein 1 (WSB1) generates three isoforms that were found to play a role in cancer cell growth and tumor progression. We have studied their expression in neuroblastoma (NB).

Methods: The behavior of the expression levels of the WSB1 isoforms was analyzed in NB cell lines, in an in vivo NB xenograft mouse model, and in primary NB tumors using real-time PCR.

The accuracy of locating the cricothyroid membrane by palpation - an intergender study.

Background: The cricothyroid membrane (CTM) is the recommended site of access to the airway during cricothyrotomy to provide emergency oxygenation. We sought to compare the ability of physicians to correctly identify the CTM in male and female patients.

Methods: In a prospective observational study, anaesthetists were asked to locate the CTM by palpation which was then identified using ultrasound and the distance between the actual and estimated margin of the CTM was measured.

Lymphopenia is detrimental to therapeutic approaches to type 1 diabetes using regulatory T cells.

One of the therapeutic approaches to type 1 diabetes (T1D) focuses on enhancement of regulatory T cell (Treg) activity, either by adoptive transfer or supplementation of supporting cytokines such as interleukin-2 (IL-2). In principle, this therapeutic design would greatly benefit of concomitant reduction in pathogenic cell burden. Experimental evidence indicates that physiological recovery from lymphopenia is dominated by evolution of effector and cytotoxic cells, which abolishes the therapeutic efficacy of Treg cells.

Anaesthesia for parturients with severe cystic fibrosis: a case series.

Cystic fibrosis affects 1 in 1600-2500 live births and is inherited in an autosomal recessive manner. It primarily involves the respiratory, gastrointestinal and reproductive tracts, with impaired clearance of, and obstruction by, increasingly viscous secretions. Severe respiratory disease, diabetes and gastro-oesophageal reflux may result.
