RESEARCH QUESTION: Is there an association between regular exercise, defined as a structured program of increased physical activity at least 1 month in duration, and improvements in measures of executive functions compared with children who engage in their normal daily activities? CONTEXT: The association between increased physical activity and changes in performance on tasks of executive functions have not been well elucidated in children. Executive functioning is important to intellectual development and academic success in children, and inexpensive, nonpharmacological methods for the treatment of executive dysfunction represent an attractive interventional target...

Erik Malmqvist defends the prohibition on kidney sales as a justifiable measure to protect individuals from harms they have not autonomously chosen. This appeal to 'group soft paternalism' requires that three conditions be met. It must be shown that some vendors will be harmed, that some will be subject to undue pressure to vend, and that we cannot feasibly distinguish between the autonomous and the non-autonomous. I argue that Malmqvist fails to demonstrate that any of these conditions are likely to obtain...

While miniature inertial sensors offer a promising means for precisely detecting, quantifying and classifying animal behaviors, versatile inertial sensing devices adapted for small, freely-moving laboratory animals are still lacking. We developed a standalone and cost-effective platform for performing high-rate wireless inertial measurements of head movements in rats. Our system is designed to enable real-time bidirectional communication between the headborne inertial sensing device and third party systems, which can be used for precise data timestamping and low-latency motion-triggered applications...

OBJECTIVE: To assess the patient's perceived causes of PCa and relation to treatment satisfaction an internet based survey study was designed. Prostate cancer (PCa) is a profoundly personal disease considering the location and common sequelae of treatment. Deeply held patient self-perceptions regarding the etiology of a patient's PCa may generate lasting beliefs that impact satisfaction with treatment selection. METHODS: Third-party web-based surveys were sent to patients receiving radical prostatectomy for clinically localized PCa...

BACKGROUND: Making forecasts about biodiversity and giving support to policy relies increasingly on large collections of data held electronically, and on substantial computational capability and capacity to analyse, model, simulate and predict using such data. However, the physically distributed nature of data resources and of expertise in advanced analytical tools creates many challenges for the modern scientist. Across the wider biological sciences, presenting such capabilities on the Internet (as "Web services") and using scientific workflow systems to compose them for particular tasks is a practical way to carry out robust "in silico" science...

Although studies often find racial disparities in policing outcomes, less is known about how suspect race biases police interactions as they unfold. This study examines what is differentially occurring during police-suspect interactions for White, Black, and Latino suspects across time. It is hypothesized that racial bias may be more evident earlier in interactions, when less information about the situation is available. One hundred thirty-nine (62 White, 42 Black, and 35 Latino) use-of-force case files and associated written narratives from a medium to large size urban police department in the United States were analyzed...

Advances in reproductive medicine have provided new, and much needed, hope for millions of people struggling with infertility. Gestational surrogacy is one such development that has been gaining popularity with infertile couples, especially those unable to benefit from other reproductive procedures such as In Vitro Fertilization. For many Muslim couples, however, surrogacy remains a nonviable option. Islamic scholars have deemed the procedure incompatible with Islam and have prohibited its use. This paper examines the arguments presented for proscribing surrogacy arrangements in Sunni Islam in particular...

BACKGROUND: The use of full-population databases is under-explored to study the use, quality and costs of end-of-life care. Using the case of Belgium, we explored: (1) which full-population databases provide valid information about end-of-life care, (2) what procedures are there to use these databases, and (3) what is needed to integrate separate databases. METHODS: Technical and privacy-related aspects of linking and accessing Belgian administrative databases and disease registries were assessed in cooperation with the database administrators and privacy commission bodies...

Young adolescents are generally considered to be self-absorbed. Studies indicate that they lack relevant general cognitive abilities, such as impulse control, that mature in early adulthood. However, their idealism may cause them to be more intolerant of unfair treatment to others and thus result in their engaging in more altruistic behavior. The present study aimed to clarify whether young adolescents are more altruistic than adults and thus indicate whether altruistic competence is domain-specific. One hundred 22 young adolescents and adults participated in a face-to-face, two-round, third-party punishment experiment...

GOALS: We compared the cost-effectiveness of traditional recommended endoscopic hemostatic therapies and Hemospray alone or in combination when treating nonvariceal upper gastrointestinal bleeding (NVUGIB). BACKGROUND: Hemospray (TC-325) is a novel endoscopic hemostatic powder, achieving hemostasis through adherence to actively bleeding biological surfaces. STUDY: A decision tree of patients with NVUGIB assessed 4 possible treatment strategies: traditional therapy alone (T), Hemospray alone (H), traditional therapy completed by Hemospray if needed (T+H), or Hemospray completed by traditional therapy if needed (H+T)...

BACKGROUND: A number of methods exist for the risk assessment of hospital inpatients to determine the likelihood of patients experiencing drug-related problems (DRPs), including manual review of a patient's medication (medication reviews) and more complex electronic assessment using decision support alerts in electronic prescribing systems. A systematic review was conducted to determine the evidence base for potential risks associated with adult hospital inpatients that could not only lead to medication-related issues but might also be directly associated with pharmacist intervention...

BACKGROUND: New direct-acting antiviral (DAA) therapy has dramatically increased cure rates for patients infected with hepatitis C virus (HCV), but has also substantially raised treatment costs. AIM: The aim of this analysis was to evaluate the therapeutic benefit and net costs (i.e. efficiency frontier) and the quality-adjusted cost of care associated with the evolution of treatment regimens for patients with HCV genotype 1 in the United States. DESIGN: A decision-analytic Markov model...

With the rapid accumulation of publicly available small RNA sequencing datasets, third-party meta-analysis across many datasets is becoming increasingly powerful. Although removing the 3´ adapter is an essential step for small RNA sequencing analysis, the adapter sequence information is not always available in the metadata. The information can be also erroneous even when it is available. In this study, we developed DNApi, a lightweight Python software package that predicts the 3´ adapter sequence de novo and provides the user with cleansed small RNA sequences ready for down stream analysis...

As a new summarized record of an individual's medical data and information, Personal Health Record (PHR) can be accessible online. The owner can control fully his/her PHR files to be shared with different users such as doctors, clinic agents, and friends. However, in an open network environment like in the Cloud, these sensitive privacy information may be gotten by those unauthorized parties and users. In this paper, we consider how to achieve PHR data confidentiality and provide fine-grained access control of PHR files in the public Cloud based on Attribute Based Encryption(ABE)...

BACKGROUND: Universities are significant contributors to research and technologies in health; however, the health needs of the world's poor are historically neglected in research. Medical discoveries are frequently licensed exclusively to one producer, allowing a monopoly and inequitable pricing. Similarly, research is often published in ways that make it inaccessible. Universities can adopt policies and practices to overcome neglect and ensure equitable access to research and its products...

Biological safety cabinets (BSCs) are the primary means of containment used in laboratories worldwide for the safe handling of infectious microorganisms. They provide protection to the laboratory worker and the surrounding environment from pathogens. To ensure the correct functioning of BSCs, they need to be properly maintained beyond the daily care routines of the laboratory. This involves annual maintenance and certification by a qualified technician in accordance to the NSF/American National Standards Institute 49-2014 Biosafety Cabinetry: Design, Construction, Performance, and Field Certification...

BACKGROUND: Twitter updates now represent an enormous stream of information originating from a wide variety of formal and informal sources, much of which is relevant to real-world events. They can therefore be highly useful for event detection and situational awareness applications. RESULTS: In this paper we apply customised filtering techniques to existing bio-surveillance algorithms to detect localised spikes in Twitter activity, showing that these correspond to real events with a high level of confidence...

INTRODUCTION: This work aims to explore radiation doses delivered in screening mammography in Australia, with a focus on whether compressed breast thickness should be used as a guide when determining patient derived diagnostic reference levels (DRLs). METHODS: Anonymized mammograms (52,405) were retrieved from a central database, and DICOM headers were extracted using third party software. Women with breast implants, breast thicknesses outside 20-110 mm and images with incomplete exposure or quality assurance (QA) data were excluded...

BACKGROUND: Vaccination against rotavirus has shown great potential for reducing the primary cause of severe childhood gastroenteritis. Previous economic evaluations of rotavirus vaccination in France have not modeled the potential impact of vaccines on disease burden via reduced transmission. OBJECTIVE: To determine the cost-effectiveness of the introduction of pentavalent rotavirus vaccination into the French infant vaccination schedule. METHODS: We developed an age-structured model of rotavirus transmission calibrated to 6 years of French gastroenteritis incidence and vaccine clinical trial data...
