BACKGROUND: Novelty-seeking (NS) and impulsive personality traits have been proposed to reflect an interplay between fronto-cortical and limbic systems, including the limbic striatum (LS). Although neuroimaging studies have provided some evidence for this, most are comprised of small samples and many report surprisingly large effects given the challenges of trying to relate a snapshot of brain function or structure to an entity as complex as personality. The current work tested a priori hypotheses about associations between striatal dopamine (DA) release, cortical thickness (CT), and NS in a large sample of healthy adults...

J Ulianko, J Janek, Ľ Laca
INTRODUCTION: Negative pressure wound therapy is one of the latest methods of dealing with complicated healing wounds. It promotes granulation, mechanically attracts the edges of the wound, removes secretions, reduces the number of bacteria in the wound and reduces swelling. In addition to its use to start and enhance the healing process, this method is also important in the fixation of split-thickness skin grafts in non-ideal conditions. The goal of this article is to establish basic indications for negative pressure fixation of meshed split-thickness skin grafts in non-ideal conditions in the wound and to assess the impact of contamination of wounds on engraftment using vacuum therapy...

BACKGROUND: Cambodia reduced malaria incidence by more than 75% between 2000 and 2015, a target of the Millennium Development Goal 6. The Cambodian Government aims to eliminate all forms of malaria by 2025. The country's malaria incidence is highly variable at provincial level, but less is known at village level. This study used passive case detection (PCD) data at village level in Ratanakiri Province from 2010 to 2014 to describe incidence trends and identify high-risk areas of malaria to be primarily targeted towards malaria elimination...

The Quality of Life in Hand Eczema Questionnaire (QOLHEQ) is the only instrument assessing disease-specific Health-Related Quality of Life (HRQOL) in hand eczema patients. It is available in eight language versions. In this study we assessed if the items of different language versions of the QOLHEQ yield comparable values across countries. An international multi-center study was conducted with participating centers in Finland, Germany, Japan, the Netherlands, Sweden and Turkey. Methods of item response theory (IRT) were applied to each subscale to assess differential item functioning (DIF) for items between countries...

In Ironman triathlon, the number of overall male and female finishers increased in the last 30 years, while an improvement in performance has been reported. Studies concluding these numbers only analysed the top ten athletes per age group instead of all finishers, therefore a selection bias might have occurred. The aim of the present study was to investigate participation, performance and the age-related performance decline of all pro and age group triathletes ranked in all Ironman triathlons held worldwide between 2002 and 2015...

Multiple antimicrobial interventions have been validated for use during the beef postharvesting process. However, little has been done to determine the impact of the postharvest environment on pathogen contamination. In this study, surrogate microorganisms were used to simulate pathogen cross-contamination through the postharvest environment at three different abattoirs. At each abattoir, the brisket areas of 13 hide-on carcasses were inoculated after stunning, with a gelatin slurry containing a cocktail (~7 log CFU/ml) of fluorescent Escherichia coli biotype I...

BACKGROUND: As one of the several effective solutions for personal privacy protection, a global unique identifier (GUID) is linked with hash codes that are generated from combinations of personally identifiable information (PII) by a one-way hash algorithm. On the GUID server, no PII is permitted to be stored, and only GUID and hash codes are allowed. The quality of PII entry is critical to the GUID system. OBJECTIVE: The goal of our study was to explore a method of checking questionable entry of PII in this context without using or sending any portion of PII while registering a subject...

We implemented a team-based activity in our exercise physiology teaching laboratory that was inspired from Abbott et al.'s classic 1952 Journal of Physiology paper titled "The physiological cost of negative work." Abbott et al. connected two bicycles via one chain. One person cycled forward (muscle shortening contractions, positive work) while the other resisted the reverse moving pedals (muscle lengthening contractions, negative work), and the cost of work was compared. This study was the first to link human whole body energetics with isolated muscle force-velocity characteristics...

PURPOSE: It is very important for calculation of clinical indices and diagnosis to detect thyroid nodules from ultrasound images. However, this task is a challenge mainly due to heterogeneous thyroid nodules with distinct components are similar to background in ultrasound images. In this study, we employ cascade deep convolutional neural networks (CNNs) to develop and evaluate a fully automatic detection of thyroid nodules from 2D ultrasound images. METHODS: Our cascade CNNs are a type of hybrid model, consisting of two different CNNs and a new splitting method...

Inhaler technique can be corrected with training, but skills drop off quickly without repeated training. The aim of our study was to explore the effect of novel inhaler technique labels on the retention of correct inhaler technique. In this single-blind randomized parallel-group active-controlled study, clinical pharmacists enrolled asthma patients using controller medication by Accuhaler [Diskus] or Turbuhaler. Inhaler technique was assessed using published checklists (score 0-9). Symptom control was assessed by asthma control test...

Renaming schizophrenia is a potential strategy to reduce the stigma attached to people with schizophrenia. However, the overall associations between renaming schizophrenia and stigma-related outcomes have not been fully elucidated. We conducted a systematic review of studies that empirically examined the outcomes between new or alternative terms and old or existing terms for schizophrenia. We searched for relevant articles in eight bibliographic databases, conducted a Google search, examined reference lists, and contacted relevant experts...

BACKGROUND: Sense of Coherence (SOC) is defined as a tendency to perceive life experiences as comprehensible, manageable and meaningful. The construct is split in three major domains: Comprehensibility, Manageability, and Meaningfulness. SOC has been associated with successful coping strategies in the face of illness and traumatic events and is a predictor of self-reported and objective health in a variety of contexts. In the present study we aim to evaluate the association of SOC with disability and dependence in Spanish elders...

BACKGROUND: The prevalence of multiple chronic conditions (MCC) among older persons is increasing worldwide and is associated with poor health status and high rates of healthcare utilization and costs. Current health and social services are not addressing the complex needs of this group or their family caregivers. A better understanding of the experience of MCC from multiple perspectives is needed to improve the approach to care for this vulnerable group. However, the experience of MCC has not been explored with a broad sample of community-living older adults, family caregivers and healthcare providers...

J-R Jhan, E R Andrechek
Current therapeutic outcomes for breast cancer underscore the complexity of treating a heterogeneous disease. Indeed, studies have shown that differences in gene expression among patients with the same subtype of breast cancer are correlated with the response to treatment. This strongly suggests that there is an urgent need to treat breast cancer with a personalized approach. Here we employed cell signaling pathway signatures to predict pathway activity in subtypes of MMTV-Myc mammary tumors. We then split tumors into subsets and developed individualized combinatorial treatments for two subtypes with distinct pathway activation patterns...

Advances in cloud computing have greatly motivated data owners to outsource their huge amount of personal multimedia data and/or computationally expensive tasks onto the cloud by leveraging its abundant resources for cost saving and flexibility. Despite the tremendous benefits, the outsourced multimedia data and its originated applications may reveal the data owner's private information, such as the personal identity, locations or even financial profiles. This observation has recently aroused new research interest on privacy-preserving computations over outsourced multimedia data...

BACKGROUND: The association between impulsive dispositions and the use of the central nervous system (CNS) depressant alcohol has been examined extensively; however, the links between other depressant use (sedatives, tranquilizers, and pain relievers) and impulsivity have been less studied, and findings have been equivocal. This may be due, in part, to varying operationalizations of "impulsivity," as well as issues related to the lumping versus splitting of various depressant substances when assessing use...

In this article, we critically reflect on the responsibilities that the food industry has for public health. Although food companies are often significant contributors to public health problems (e.g., obesity, type 2 diabetes), the mere possibility of corporate responsibility for public health seems to be excluded in the academic public health discourse. We argue that the behavior of several food companies reflects a split corporate personality, as they contribute to public health problems and simultaneously engage in activities to prevent them...
