OBJECTIVE: Being overweight makes physical movement more difficult. Our aim was to investigate the association between body composition and motor performance in preschool children. METHODS: A total of 476 predominantly normal-weight preschool children (age 3.9 ± 0.7 years; m/f: 251/225; BMI 16.0 ± 1.4 kg/m2) participated in the Swiss Preschoolers' Health Study (SPLASHY). Body composition assessments included skinfold thickness, waist circumference (WC), and BMI...

Detection and toxicity assessment of waterborne contaminants are crucial for protecting human health and the environment. Development of easy-to-implement, rapid and cost-effective tools to measure anthropogenic effects on watersheds are critical for responsible management, particularly in times of increasing development and urbanization. Traditionally, environmental toxicology has focused on limited endpoints, such as lethality and fertility, which are directly affecting population levels. However, more sensitive readings are needed to assess sub-lethal effects...

BACKGROUND: Muscle stiffness of the lumbar back muscles in low back pain (LBP) patients has not been clearly elucidated because quantitative assessment of the stiffness of individual muscles was conventionally difficult. This study aimed to examine the association of LBP with muscle stiffness assessed using ultrasonic shear wave elastography (SWE) and muscle mass of the lumbar back muscle, and spinal alignment in young and middle-aged medical workers. METHODS: The study comprised 23 asymptomatic medical workers [control (CTR) group] and 9 medical workers with LBP (LBP group)...

Proponents of "enhanced interrogation techniques" in the United States have claimed that such methods are necessary for obtaining information from uncooperative terrorism subjects. In the present article, we offer an informed, academic perspective on such claims. Psychological theory and research shows that harsh interrogation methods are ineffective. First, they are likely to increase resistance by the subject rather than facilitate cooperation. Second, the threatening and adversarial nature of harsh interrogation is often inimical to the goal of facilitating the retrieval of information from memory and therefore reduces the likelihood that a subject will provide reports that are extensive, detailed, and accurate...

The direct anterior (DA) approach for total hip arthroplasty (THA) has become increasingly popular. However, femoral access can be more technically challenging in difficult cases as compared with other approaches. Conjoint tendon release can improve proximal femoral exposure, but its effect on patient function and pain has not been studied. This study evaluated the effect of conjoint tendon release on length of stay (LOS), inpatient pain medication requirements, and functional outcomes of patients undergoing DA THA...

Quality problem: Although widely utilized in resource-rich health care systems, the use of quality improvement (QI) techniques is less common in resource-limited environments. Uganda is a resource-limited country in Sub-Saharan Africa that faces many challenges with health care delivery. These challenges include understaffing, inconsistent drug availability and inefficient systems that limit the provision of clinical care. Initial assessment: Poor adherence to prescribed inpatient medications was identified as a key shortcoming of clinical care on the internal medicine wards of Mulago National Referral Hospital, Kampala, Uganda...

The phylogeny of eutherian mammals contains some of the most recalcitrant nodes in the tetrapod tree of life. We combined comprehensive taxon and character sampling to explore three of the most debated interordinal relationships among placental mammals. We performed in silico extraction of ultraconserved element loci from 72 published genomes and invitro enrichment and sequencing of ultraconserved elements from 28 additional mammals, resulting in alignments of 3,787 loci. We analyzed these data using concatenated and multispecies coalescent phylogenetic approaches, topological tests, and exploration of support among individual loci to identify the root of Eutheria and the sister groups of tree shrews (Scandentia) and horses (Perissodactyla)...

Accurate and robust tomographic reconstruction from dynamic positron emission tomography (PET) acquired data is a difficult problem. Conventional methods, such as the maximum likelihood expectation maximization (MLEM) algorithm for reconstructing the activity distribution-based on individual frames, may lead to inaccurate results due to the checkerboard effect and limitation of photon counts. In this paper, we propose a stacked sparse auto-encoder based reconstruction framework for dynamic PET imaging. The dynamic reconstruction problem is formulated in a deep learning representation, where the encoding layers extract the prototype features, such as edges, so that, in the decoding layers, the reconstructed results are obtained through a combination of those features...

Successfully launched on 30 May 2016, ZY3-02 is the first Chinese surveying and mapping satellite equipped with a lightweight laser altimeter. Calibration is necessary before the laser altimeter becomes operational. Laser footprint location prediction is the first step in calibration that is based on ground infrared detectors, and it is difficult because the sample frequency of the ZY3-02 laser altimeter is 2 Hz, and the distance between two adjacent laser footprints is about 3.5 km. In this paper, we build an on-orbit rigorous geometric prediction model referenced to the rigorous geometric model of optical remote sensing satellites...

BACKGROUND: PM2.5 precursor emissions have declined over the course of several decades, following the implementation of local, state, and federal air quality policies. Estimating the corresponding change in population exposure and PM2.5-attributable risk of death prior to the year 2000 is made difficult by the lack of PM2.5 monitoring data. OBJECTIVES: We used a new technique to estimate historical PM2.5 concentrations, and estimated the effects of changes in PM2...

Advances in breast cancer management, including breast-conserving surgery, have resulted in an increase in the incidence of breast oedema. However, this is addressed by professionals less often than arm lymphoedema. Breast oedema results in significant physical and psychological morbidity, makes finding a comfortably fitting bra very difficult, and can act as a reminder of the initial breast cancer diagnosis. Psychological difficulties can be compounded by clinicians' failure to acknowledge the impact. Assessing and managing breast oedema requires a sensitive, skilled approach to ensure all the relevant issues are identified and addressed in a comprehensive care plan; taking time to listen to patients and acknowledging the impact can be very therapeutic...

Machine learning algorithms increasingly influence our decisions and interact with us in all parts of our daily lives. Therefore, just as we consider the safety of power plants, highways, and a variety of other engineered socio-technical systems, we must also take into account the safety of systems involving machine learning. Heretofore, the definition of safety has not been formalized in a machine learning context. In this article, we do so by defining machine learning safety in terms of risk, epistemic uncertainty, and the harm incurred by unwanted outcomes...

Recent studies show the remarkable power of fine-grained information disclosed by users on social network sites to infer users' personal characteristics via predictive modeling. Similar fine-grained data are being used successfully in other commercial applications. In response, attention is turning increasingly to the transparency that organizations provide to users as to what inferences are drawn and why, as well as to what sort of control users can be given over inferences that are drawn about them. In this article, we focus on inferences about personal characteristics based on information disclosed by users' online actions...

The centenary of the October Revolution in 1917 provides a timely opportunity to assess the legacies of that event. I examine the role of the revolution in public health with a focus on nursing, assessing the Imperial Russian health care system, the development of Soviet nursing, and current plans for nursing and public health care in Putin's Russia. Analyzing nursing shows that there was a great deal of continuity in terms of medical personnel and ideas on how public health care service in Russia should operate...

The partitioning of solute molecules between immiscible solvents with significantly different polarities is of great importance. The polarization between the solute and solvent molecules plays an essential role in determining the solubility of the solute, which makes computational studies utilizing molecular mechanics (MM) rather difficult. In contrast, quantum mechanics (QM) can provide more reliable predictions. In this work, the partition coefficients of the side chain analogs of some amino acids between water and chloroform were computed...

Distorted surface regions (5-6 nm) with an unusual layered-like structure on LiMn2O4 cathode material were directly observed after it was cycled (3-4.9 V), indicating a possible spinel-to-layered structural transformation. Formation of these distorted regions severely degrades LiMn2O4 cathode capacity. Getting a better understanding of the exact crystal structure of the distorted regions, the structural transformation pathways and the origins of the distortion is made difficult by the regions' nanoscopic size...

Upper and lower extremity injuries are common in children, with an overall risk of fracture estimated at just under 1 in 5 children. Pediatric bone anatomy and physiology produce age specific injury patterns and conditions that are unique to children, which can make accurate diagnosis difficult for emergency clinicians. This issue reviews the etiology and pathophysiology of child-specific fractures, as well as common injuries of the upper and lower extremities. Evidence-based recommendations for management of pediatric fractures, including appropriate diagnostic studies and treatment, are also discussed...

Many biologically and chemically based approaches have been developed to design highly active and selective protease substrates and probes. It is, however, difficult to find substrate sequences that are truly selective for any given protease, as different proteases can demonstrate a great deal of overlap in substrate specificities. In some cases, better enzyme selectivity can be achieved using peptide libraries containing unnatural amino acids such as the hybrid combinatorial substrate library (HyCoSuL), which uses both natural and unnatural amino acids...

Purpose The purpose of this paper is to explore the human work entailed in the deployment of digital health care technology. It draws on imagined configurations of computers and machines in fiction and social science to think about the relationship between technology and people, and why this makes implementation of digital technology so difficult. The term hubots is employed as a metaphorical device to examine how machines and humans come together to do the work of healthcare. Design/methodology/approach This paper uses the fictional depiction of hubots to reconceptualise the deployment of a particular technology - a computer decision support system (CDSS) used in emergency and urgent care services...
