Study protocol of European Fans in Training (EuroFIT): a four-country randomised controlled trial of a lifestyle program for men delivered in elite football clubs.

Background: Lifestyle interventions targeting physical activity, sedentary time and dietary behaviours have the potential to initiate and support behavioural change and result in public health gain. Although men have often been reluctant to engage in such lifestyle programs, many are at high risk of several chronic conditions. We have developed an evidence and theory-based, gender sensitised, health and lifestyle program (European Fans in Training (EuroFIT)), which is designed to attract men through the loyalty they feel to the football club they support.

Process evaluation of the Albany Physical Activity and Nutrition (APAN) program, a home-based intervention for metabolic syndrome and associated chronic disease risk in rural Australian adults.

Issue addressed The Albany Physical Activity and Nutrition (APAN) study investigated the effects of the APAN program, a home-based intervention on dietary and physical activity behaviours and chronic disease risk for rural Australian adults. This paper reports on the process evaluation to gain insight into the link between intervention elements and outcomes. Methods The APAN program comprised resources to improve participants' diet and physical activity.

Health Behaviors and their Relationship with Disease Control in People Attending Genetic Clinics with a Family History of Breast or Colorectal Cancer.

The current work aimed to assess health behaviors, perceived risk and control over breast/colorectal cancer risk and views on lifestyle advice amongst attendees at cancer family history clinics. Participants attending the East of Scotland Genetics Service were invited to complete a questionnaire (demographic data, weight and height, health behaviors and psycho-social measures of risk and perceived control) and to participate in an in-depth interview. The questionnaire was completed by 237 (49 %) of attendees, ranging from 18 to 77 years (mean age 46 (±10) years).

Perceived diagnostic delay and cancer-related distress: a cross-sectional study of patients with colorectal cancer.

Objective: This study aimed to examine the effect of perceived diagnostic delay on cancer-related distress and determine whether fear of cancer-recurrence and quality of life mediate this relationship.

Methods: Cross-sectional study in which 311 colorectal cancer (CRC) survivors in Scotland completed a survey, which included questions on cancer-related distress (IES-R), perceived diagnostic delay, quality of life (trial outcome index of the FACT-C: FACT-C TOI) and fear of cancer recurrence. Fifteen patients withheld consent to data matching with medical records, leaving a sample size of 296.

Multiscale modelling of solid tumour growth: the effect of collagen micromechanics.

Here we introduce a model of solid tumour growth coupled with a multiscale biomechanical description of the tumour microenvironment, which facilitates the explicit simulation of fibre-fibre and tumour-fibre interactions. We hypothesise that such a model, which provides a purely mechanical description of tumour-host interactions, can be used to explain experimental observations of the effect of collagen micromechanics on solid tumour growth. The model was specified to mouse tumour data, and numerical simulations were performed.

Phosphorylation of a splice variant of collapsin response mediator protein 2 in the nucleus of tumour cells links cyclin dependent kinase-5 to oncogenesis.

Background: Cyclin-dependent protein kinase-5 (CDK5) is an unusual member of the CDK family as it is not cell cycle regulated. However many of its substrates have roles in cell growth and oncogenesis, raising the possibility that CDK5 modulation could have therapeutic benefit. In order to establish whether changes in CDK5 activity are associated with oncogenesis one could quantify phosphorylation of CDK5 targets in disease tissue in comparison to appropriate controls.

Awareness of Lifestyle and Colorectal Cancer Risk: Findings from the BeWEL Study.

It is estimated that 47% of colorectal cancers (CRC) could be prevented by appropriate lifestyles. This study aimed to identify awareness of the causes of CRC in patients who had been diagnosed with a colorectal adenoma through the Scottish Bowel Screening Programme and subsequently enrolled in an intervention trial (using diet and physical activity education and behavioural change techniques) (BeWEL). At baseline and 12-month follow-up, participants answered an open-ended question on factors influencing CRC development.

Addressing overtreatment of screen detected DCIS; the LORIS trial.

Overdiagnosis, and thus overtreatment, are inevitable consequences of most screening programmes; identification of ways of minimising the impact of overdiagnosis demands new prospective research, in particular the need to separate clinically relevant lesions that require active treatment from those that can be safely left alone or monitored and only need treated if they change characteristics. Breast cancer screening has led to a large increase in ductal carcinoma in situ (DCIS) diagnoses. This is a widely heterogeneous disease and most DCIS detected through screening is of high cytonuclear grade and therefore likely to be important clinically.

Invited commentary on … Lithium treatment and risk for dementia in adults with bipolar disorder.

Alzheimer's disease clinical trials are failing at an alarming rate, highlighting the desperate need for novel thinking to combat this escalating health crisis. A recent large-scale population study indicates that lithium treatment reduces dementia development, supporting preclinical mechanistic evidence that this commonly used agent might be clinically valuable in dementia.

The Psychological Impact of a Colorectal Cancer Diagnosis Following a Negative Fecal Occult Blood Test Result.

Background: Screening using fecal occult blood testing (FOBt) reduces colorectal cancer mortality, but the test has low sensitivity. A "missed" cancer may cause psychologic harms in the screened population that partially counteract the benefits of early detection.

Methods: Three hundred and eleven people diagnosed with colorectal cancer (i) after a negative FOBt result (interval cancer), (ii) a positive result (screen-detected cancer), or (iii) in regions where screening was not offered, completed questions on quality of life (FACT-C), depression (CES-D), perceived diagnostic delay, and trust in the results of FOBt screening.

A randomised controlled trial of a physical activity and nutrition program targeting middle-aged adults at risk of metabolic syndrome in a disadvantaged rural community.

Background: Approximately 70% of Australian adults aged over 50 are overweight or obese, with the prevalence significantly higher in regional/remote areas compared to cities. This study aims to determine if a low-cost, accessible lifestyle program targeting insufficiently active adults aged 50-69 y can be successfully implemented in a rural location, and whether its implementation will contribute to the reduction/prevention of metabolic syndrome, or other risk factors for type 2 diabetes, and cardiovascular disease.

Methods/design: This 6-month randomised controlled trial will consist of a nutrition, physical activity, and healthy weight intervention for 50-69 year-olds from a disadvantaged rural community.

Kidney biopsy findings in primary Sjögren syndrome.

Background: Renal involvement is rare in primary Sjögren syndrome (PSS). In this study, we examined renal biopsy findings in patients with PSS and correlated them with their clinical and renal findings.

Methods: Twenty-five patients with PSS who underwent renal biopsies from two renal units in Scotland between 1978 and 2013 were identified from renal biopsy database.

SPRTN is a new player in an old story.

A new study identifies rare mutations in SPRTN that cause a novel progeroid syndrome. The results point to an unexpected function of SPRTN and bring insight to the mechanisms that link premature aging and cancer.

The impact of a bodyweight and physical activity intervention (BeWEL) initiated through a national colorectal cancer screening programme: randomised controlled trial.

Objective: To evaluate the impact of a diet and physical activity intervention (BeWEL) on weight change in people with a body mass index >25 weight (kg)/height (m)(2) at increased risk of colorectal cancer and other obesity related comorbidities.

Design: Multicentre, parallel group, randomised controlled trial.

Setting: Four Scottish National Health Service health boards.

Prolonged inhibition of 5-HT₃ receptors by palonosetron results from surface receptor inhibition rather than inducing receptor internalization.

Background And Purpose: The 5-HT₃ receptor antagonist palonosetron is an important treatment for emesis and nausea during cancer therapy. Its clinical efficacy may result from its unique binding and clearance characteristics and receptor down-regulation mechanisms. We investigated the mechanisms by which palonosetron exerts its long-term inhibition of 5-HT₃ receptors for a better understanding of its clinical efficacy.

Cholinergic pesticides cause mushroom body neuronal inactivation in honeybees.

Pesticides that target cholinergic neurotransmission are highly effective, but their use has been implicated in insect pollinator population decline. Honeybees are exposed to two widely used classes of cholinergic pesticide: neonicotinoids (nicotinic receptor agonists) and organophosphate miticides (acetylcholinesterase inhibitors). Although sublethal levels of neonicotinoids are known to disrupt honeybee learning and behaviour, the neurophysiological basis of these effects has not been shown.

The microsporidian parasites Nosema ceranae and Nosema apis are widespread in honeybee (Apis mellifera) colonies across Scotland.

Nosema ceranae is spreading into areas where Nosema apis already exists. N. ceranae has been reported to cause an asymptomatic infection that may lead, ultimately, to colony collapse.

A high-fat-diet-induced cognitive deficit in rats that is not prevented by improving insulin sensitivity with metformin.

Aims/hypothesis: We previously demonstrated that animals fed a high-fat (HF) diet for 10 weeks developed insulin resistance and behavioural inflexibility. We hypothesised that intervention with metformin would diminish the HF-feeding-evoked cognitive deficit by improving insulin sensitivity.

Methods: Rats were trained in an operant-based matching and non-matching to position task (MTP/NMTP).

Lifestyle issues for colorectal cancer survivors--perceived needs, beliefs and opportunities.

Purpose: As survival rates for patients treated with colorectal cancer (CRC) increase, it is important to consider the short- and long-term self-management needs. The current work aimed to explore perceived patient needs for advice on diet, activity and beliefs about the role of lifestyle for reducing disease recurrence.

Methods: Forty colorectal cancer survivors, aged between 27 and 84, participated in six focus groups in community locations in the UK.

Models of dementia: an introductory overview.

The analysis of the molecular development of AD (Alzheimer's disease) is technically challenging, due to the chronic nature of the disease, the lack of early and definitive clinical diagnosis, and the fact that the abnormal molecular pathology occurs in the brain. Therefore appropriate animal models of AD are essential if we are to dissect the processes leading to molecular pathology, and ultimately to test the efficacy of potential therapies before clinical studies. Unfortunately, there is controversy over the benefits of the available models, the only consensus of opinion being that no perfect model currently exists.

RIC-3 exclusively enhances the surface expression of human homomeric 5-hydroxytryptamine type 3A (5-HT3A) receptors despite direct interactions with 5-HT3A, -C, -D, and -E subunits.

Although five 5-hydroxytryptamine type 3 (5-HT3) subunits (A-E) have been cloned, knowledge on the regulation of their assembly is limited. RIC-3 has been identified as a chaperone specific for the pentameric ligand-gated nicotinic acetylcholine and 5-HT(3) receptors. Therefore, we examined the impact of RIC-3 on differently composed 5-HT(3) receptors with the focus on 5-HT3C, -D, and -E subunits.

Rapid dendritic and axonal responses to neuronal insults.

Glutamate is the major excitatory neurotransmitter in the mammalian central nervous system playing critical roles in basal synaptic transmission and mechanisms of learning and memory. Under normal conditions, glutamate is sequestered within synaptic vesicles (approximately 100 mM) with extracellular glutamate concentrations being limited (<1 microM), via retrieval by plasma-membrane transporters on neuronal and glial cells. In the case of central nervous system trauma, stroke, epilepsy, and in certain neurodegenerative diseases, increased concentrations of extracellular glutamate (by vesicular release, cell lysis and/or decreased glutamate transporter uptake/reversal) stimulate the overactivation of local ionotropic glutamate receptors that trigger neuronal cell death (excitotoxicity).
