Perceived body acceptance by personal trainers and client body appreciation in women in the UK: A pre-registered study.

Research is yet to consider the potential for personal trainers (PTs) to influence their client's thoughts and feelings surrounding their body. This pre-registered study explored a model of positive body image in women personal training clients in the UK. Participants (n = 234, mean age = 51) completed an online questionnaire assessing body mass index (BMI), perceived body acceptance by their PT and various other measures related to body image.

Estimated reduction in human salmonellosis incidence in Canada from a new government requirement to reduce in frozen breaded chicken products.

Nontyphoidal infections are a leading cause of enteric disease in Canada, most commonly associated with foodborne exposures. Raw frozen breaded chicken products (FBCP) have been implicated in 16 outbreaks between 2017 and 2019. This study quantified the impact of the 1 April 2019 requirement by the Canadian Food Inspection Agency (CFIA) for manufacturers to reduce in raw FBCP.

Understanding how nurses can effectively utilise social media for increasing public involvement, recruitment and impact dissemination of Clinical Research Trials.

Background: The methodologies for clinical research trials are evolving to greater usage of social media platforms, providing opportunities to incorporate smart technologies in their delivery. Research Nurses should consider how they can utilise platforms for public engagement in trials.

Aim: To explore the experiences of social media platforms and clinical research trials in a healthy population group, to gain insight into how clinical researchers can utilise these platforms professionally and ethically.

Phase retrieval in propagation-based X-ray imaging beyond the limits of transport of intensity and contrast transfer function approaches.

We derive a phase retrieval formula for propagation-based phase contrast X-ray imaging that does not require weakly attenuating objects or short propagation distances. It is directly applicable to both single- and multiple-distance scenarios. We show the validity conditions and study the error of the underlying mutual intensity approximation, which uses the common assumptions of weak phase shift variations and phase-attenuation duality.

Continuous and discrete proportion elicit different cognitive strategies.

Despite proportional information being ubiquitous, there is not a standard account of proportional reasoning. Part of the difficulty is that there are several apparent contradictions: in some contexts, proportion is easy and privileged, while in others it is difficult and ignored. One possibility is that although we see similarities across tasks requiring proportional reasoning, people approach them with different strategies.

Biochemical characterisation and production kinetics of high molecular-weight (HMW) putative antibacterial proteins of insect pathogenic Brevibacillus laterosporus isolates.

Background: Bacterial genomes often encode structures similar to phage capsids (encapsulins) and phage tails which can be induced spontaneously or using genotoxic compounds such as mitomycin C. These high molecular-weight (HMW) putative antibacterial proteins (ABPs) are used against the competitive strains under natural environment. Previously, it was unknown whether these HMW putative ABPs originating from the insect pathogenic Gram-positive, spore-forming bacterium Brevibacillus laterosporus (Bl) isolates (1821L, 1951) are spontaneously induced during the growth and pose a detrimental effect on their own survival.

The impact of different imputation methods on estimates and model performance: an example using a risk prediction model for premature mortality.

Objective: To compare how different imputation methods affect the estimates and performance of a prediction model for premature mortality.

Study Design And Setting: Sex-specific Weibull accelerated failure time survival models were run on four separate datasets using complete case, mode, single and multiple imputation to impute missing values. Six performance measures were compared to access predictive accuracy (Nagelkerke R, integrated brier score), discrimination (Harrell's c-index, discrimination slope) and calibration (calibration in the large, calibration slope).

Rate and Location of Reulceration and Reamputation After Partial First-Ray Amputation versus Hallux Amputation in Diabetic and Nondiabetic Populations.

Background: We sought to determine the rates of reulceration and reamputation in individuals who underwent partial first-ray amputations versus hallux amputations in diabetic and nondiabetic populations.

Methods: Eighty-four amputations were reviewed in a retrospective fashion. A retrospective medical record review was performed to determine patients who underwent a hallux amputation, both partial and complete, and patients who underwent a partial first-ray amputation.

A study protocol for a predictive model to assess population-based avoidable hospitalization risk: Avoidable Hospitalization Population Risk Prediction Tool (AvHPoRT).

Introduction: Avoidable hospitalizations are considered preventable given effective and timely primary care management and are an important indicator of health system performance. The ability to predict avoidable hospitalizations at the population level represents a significant advantage for health system decision-makers that could facilitate proactive intervention for ambulatory care-sensitive conditions (ACSCs). The aim of this study is to develop and validate the Avoidable Hospitalization Population Risk Tool (AvHPoRT) that will predict the 5-year risk of first avoidable hospitalization for seven ACSCs using self-reported, routinely collected population health survey data.

Stepwise assembly and release of Tc toxins from Yersinia entomophaga.

Tc toxins are virulence factors of bacterial pathogens. Although their structure and intoxication mechanism are well understood, it remains elusive where this large macromolecular complex is assembled and how it is released. Here we show by an integrative multiscale imaging approach that Yersinia entomophaga Tc (YenTc) toxin components are expressed only in a subpopulation of cells that are 'primed' with several other potential virulence factors, including filaments of the protease M66/StcE.

A national cohort study of community belonging and its influence on premature mortality.

Background: Community belonging, an important constituent of subjective well-being, is an important target for improving population health. Ageing involves transitioning across different social conditions thus, community belonging on health may vary across the life course. Using a nationally representative cohort, this study estimates the life stage-specific impact of community belonging on premature mortality.

Undertaking multi-centre randomised controlled trials in primary care: learnings and recommendations from the PULsE-AI trial researchers.

Background: Conducting effective and translational research can be challenging and few trials undertake formal reflection exercises and disseminate learnings from them. Following completion of our multicentre randomised controlled trial, which was impacted by the COVID-19 pandemic, we sought to reflect on our experiences and share our thoughts on challenges, lessons learned, and recommendations for researchers undertaking or considering research in primary care.

Methods: Researchers involved in the Prediction of Undiagnosed atriaL fibrillation using a machinE learning AlgorIthm (PULsE-AI) trial, conducted in England from June 2019 to February 2021 were invited to participate in a qualitative reflection exercise.

A Review on Microbiological Source Attribution Methods of Human Salmonellosis: From Subtyping to Whole-Genome Sequencing.

is one of the main causes of human foodborne illness. It is endemic worldwide, with different animals and animal-based food products as reservoirs and vehicles of infection. Identifying animal reservoirs and potential transmission pathways of is essential for prevention and control.

The QseB response regulator imparts tolerance to positively charged antibiotics by controlling metabolism and minor changes to LPS.

The modification of lipopolysaccharide (LPS) in and spp. is primarily controlled by the two-component system PmrAB. LPS modification allows bacteria to avoid killing by positively charged antibiotics like polymyxin B (PMB).

Multiple mechanisms contribute to isolation by environment in the redheaded pine sawfly, Neodiprion lecontei.

Isolation by environment (IBE) is a population genomic pattern that arises when ecological barriers reduce gene flow between populations. Although current evidence suggests IBE is common in nature, few studies have evaluated the underlying mechanisms that generate IBE patterns. In this study, we evaluate five proposed mechanisms of IBE (natural selection against immigrants, sexual selection against immigrants, selection against hybrids, biased dispersal, and environment-based phenological differences) that may give rise to host-associated differentiation within a sympatric population of the redheaded pine sawfly, Neodiprion lecontei, a species for which IBE has previously been detected.

The effect of sleep disorders on dementia risk in patients with traumatic brain injury: A large-scale cohort study.

Introduction: We investigated the association between sleep disorders (SDs) and incident dementia in adults with traumatic brain injury (TBI).

Methods: Adults with a TBI between 2003 and 2013 were followed until incident dementia. Sleep disorders at TBI were predictors in Cox regression models, controlling for other dementia risks.
