INTRODUCTION: Prostate and breast cancer screening in older patients continue to be controversial. Balancing the desire for early detection with avoidance of over-diagnosis has led to competing and contradictory guidelines for both practices. Despite similarities, it is not known how these screening practices are related at the regional level. In this study, we examined how screening PSA and mammography are related within healthcare regions, and, to better understand what may be driving these practices, whether they are associated with local intensity of care...

OBJECTIVE: Most smokers want to quit but most cessation attempts end in failure. Alcohol consumption is associated with smoking behavior and relapse. We examined the associations between severity of drinking and psychological processes during a cessation attempt in the laboratory and during a quit attempt. METHODS: Smokers (N=209) enrolled in a smoking cessation study were followed from 2 weeks pre-quit through 4 weeks post-quit. Participants scoring 0-7 and 8-15 on the Alcohol Use Disorders Identification Test (AUDIT) were classified as low-risk and high-risk drinkers, respectively...

We extend two-species models of individual aggregation or clustering to two-dimensional spatial domains, allowing for more realistic movement of the populations compared with one spatial dimension. We assume that the domain is bounded and that there is no flux into or out of the domain. The motion of the species is along fitness gradients which allow the species to seek out a resource. In the case of competition, species which exploit the resource alone will disperse while avoiding one another. In the case where one of the species is a predator or generalist predator which exploits the other species, that species will tend to move toward the prey species, while the prey will tend to avoid the predator...

To maintain energy homeostasis, orexigenic (appetite-inducing) and anorexigenic (appetite suppressing) brain systems functionally interact to regulate food intake. Within the hypothalamus, neurons that express agouti-related protein (AgRP) sense orexigenic factors and orchestrate an increase in food-seeking behavior. In contrast, calcitonin gene-related peptide (CGRP)-expressing neurons in the parabrachial nucleus (PBN) suppress feeding. PBN CGRP neurons become active in response to anorexigenic hormones released following a meal, including amylin, secreted by the pancreas, and cholecystokinin (CCK), secreted by the small intestine...

We conducted a study of 19 biology instructors participating in small, local groups at six research-intensive universities connected to the Automated Analysis of Constructed Response (AACR) project (www.msu.edu/∼aacr). Our aim was to uncover participants' motivation to persist in a long-term teaching professional development effort, a topic that is understudied in discipline-based educational research. We interviewed each participant twice over a 2-year period and conducted qualitative analyses on the data, using expectancy-value theory as a framework for considering motivation...

INTRODUCTION: New interventions are required to reduce unintended pregnancies among female sex workers (FSWs) in low- and middle-income countries and to improve their nutritional health. Given sex workers' high mobile phone usage, repeated exposure to short messaging service (SMS) messages could address individual and interpersonal barriers to contraceptive uptake and better nutrition. METHODS: In this two-arm cluster randomised trial, each arm constitutes an equal-attention control group for the other...

BACKGROUND: While cardiac rehabilitation has been shown to be effective at improving coronary heart disease (CHD), participation is generally poor. Attempts to increase uptake and adherence often fail. Use of a Facebook intervention for this population may be a unique opportunity to support self-determined motivation and affect adherence. OBJECTIVE: To evaluate the impact of a Facebook intervention on motivation for exercise and adherence to cardiac rehabilitation in patients with CHD during a 12-week, Phase II cardiac rehabilitation program...

The study aim was to evaluate the effects of concept-based learning by comparing ATI Nursing Education test scores for a traditional curriculum and a concept-based curriculum. The study also examined effects of the concept-based curriculum on critical thinking and motivation. No statistically significant differences were noted in ATI scores for the two groups; students neither agreed nor disagreed that they were engaged in critical thinking but did agree with motivation statements. Faculty were surveyed about their approach to teaching...

Adverse effects and resistance to metronidazole have motivated the search for new antiamoebic agents against Entamoeba histolytica. Control of amoeba growth may be achieved by inhibiting the function of the glycolytic enzyme and pyruvate phosphate dikinase (PPDK). In this study, we screened 10 compounds using an in vitro PPDK enzyme assay. These compounds were selected from a virtual screening of compounds in the National Cancer Institute database. The antiamoebic activity of the selected compounds was also evaluated by determining minimal inhibitory concentrations (MICs) and IC50 values using the nitro-blue tetrazolium reduction assay...

Celebrities can have a powerful influence on people's health-related attitudes and behaviors, often by publicly disclosing their own personal health decisions. In May 2013, Angelina Jolie, an internationally recognized actress, director, and author, wrote an op-ed for the New York Times disclosing her decision to undergo a prophylactic double mastectomy to reduce her risk of breast cancer after learning that she carried the BRCA1 gene mutation. This cross-sectional study examined whether exposure to Angelina Jolie and her mastectomy disclosure and parasocial involvement (PSI) with Angelina Jolie were related to female college students' perceived risk of breast cancer and breast cancer screening intentions...

Activity recognition in smart homes aims to infer the particular activities of the inhabitant, the aim being to monitor their activities and identify any abnormalities, especially for those living alone. In order for a smart home to support its inhabitant, the recognition system needs to learn from observations acquired through sensors. One question that often arises is which sensors are useful and how many sensors are required to accurately recognise the inhabitant's activities? Many wrapper methods have been proposed and remain one of the popular evaluators for sensor selection due to its superior accuracy performance...

PURPOSE: This study sought to undertake an exploratory analysis of the impact of therapeutic alliance and dysfunctional attitudes (perfectionism and need for approval) on outcomes for participants receiving therapist-delivered and eHealth interventions for comorbid depression and alcohol/cannabis use problems. These factors have been shown in previous research to moderate response to psychological treatment for depression and related disorders. METHOD: Participants (N = 274) with concurrent depression and alcohol/cannabis misuse were randomized to 10 sessions of therapist-delivered cognitive behavior therapy/motivational interviewing (CBT/MI), computer-delivered CBT/MI with brief therapist assistance (SHADE CBT/MI), or supportive counseling (PCT)...

Prosocial acts - those that are costly to ourselves but benefit others - are a central component of human co-existence1-3. While the financial and moral costs of prosocial behaviours are well understood4-6, everyday prosocial acts do not typically come at such costs. Instead, they require effort. Here, using computational modelling of an effort-based task we show that people are prosocially apathetic. They are less willing to choose to initiate highly effortful acts that benefit others compared to benefitting themselves...

INTRODUCTION: Parkinson's disease patients carrying a heterozygous mutation in the gene glucocerebrosidase (GBA-PD) show faster motor and cognitive decline than idiopathic Parkinson's disease (iPD) patients, but the mechanisms behind this observation are not well understood. Successful dual tasking (DT) requires a smooth integration of motor and nonmotor operations. This study compared the DT performances between GBA-PD and iPD patients. METHODS: Eleven GBA-PD patients (p...

Major Depression is a prevalent mental disorder that is characterized by negative mood and reduced motivation, and frequently results in social withdrawal and memory-related deficits. Repeated stressors, such as adverse life events, increase the risk for development of the disorder. Consequently, individual variability in stress response greatly weighs on depression-vulnerability and -resilience. Here, we employed the social defeat-induced persistent stress (SDPS) paradigm to identify depression-prone individuals and to examine the temporal development of depression in the months following exposure to brief defeat stress...

PURPOSE: Apathy as a state of decreased motivation has not been highlighted in people with epilepsy (PWE). We investigated its clinical significance in PWE. METHODS: We invited adult PWE who had been administered antiepileptic drugs (AEDs) for at least 1year and compared them with age- and gender-matched healthy controls. Eligible participants completed several questionnaires including the Apathy Evaluation Scale-Self (AES-S), the Korean version of the Neurological Disorders Depression Inventory for Epilepsy (K-NDDI-E), the Generalized Anxiety Disorder-7 (GAD-7), the Epworth Sleepiness Scale (ESS), and the Insomnia Severity Index (ISI), and the Quality of Life in Epilepsy-10 (QOLIE-10)...

Parental mentalizing-recognizing that children are separate psychological entities, who have their own thoughts, wishes, and intentions that motivate their behaviors-is traditionally considered a verbal, linguistic capacity. This paper aimed to examine the relation between parental verbal mentalizing (parental reflective function; PRF) and its nonverbal form-parental embodied mentalizing (PEM)-and how both constructs contribute to parents' subjective experience of parenting, namely parental stress and coparental alliance...
