Aging is associated with a large heterogeneity in the extent of age-related changes in sensory, motor, and cognitive functions. All these functions can influence the performance in complex tasks like car driving. The present study aims to identify potential differences in underlying cognitive processes that may explain inter-individual variability in driving performance. Younger and older participants performed a one-hour monotonous driving task in a driving simulator under varying crosswind conditions, while behavioral and electrophysiological data were recorded...

REVIEW
Dino Trtovac, Joon Lee
BACKGROUND: Malnutrition is a condition most commonly arising from the inadequate consumption of nutrients necessary to maintain physiological health and is associated with the development of cardiovascular disease, osteoporosis, and sarcopenia. Malnutrition occurring in the hospital setting is caused by insufficient monitoring, identification, and assessment efforts. Furthermore, the ability of health care workers to identify and recognize malnourished patients is suboptimal. Therefore, interventions focusing on the identification and treatment of malnutrition are valuable, as they reduce the risks and rates of malnutrition within hospitals...

Mengshu Sun, Yuankun Xue, Paul Bogdan, Jian Tang, Yanzhi Wang, Xue Lin
Recently, a new approach has been introduced that leverages and over-provisions energy storage devices (ESDs) in data centers for performing power capping and facilitating capex/opex reductions, without performance overhead. To fully realize the potential benefits of the hierarchical ESD structure, we propose a comprehensive design, control, and provisioning framework including (i) designing power delivery architecture supporting hierarchical ESD structure and hybrid ESDs for some levels, as well as (ii) control and provisioning of the hierarchical ESD structure including run-time ESD charging/discharging control and design-time determination of ESD types, homogeneous/hybrid options, ESD provisioning at each level...

Psychophysiological requirements of chess players are poorly understood, and periodization of training is often made without any empirical basis. For this reason, the aim of the present study was to investigate the psychophysiological response and quantify the player internal load during, and after playing a chess game. The participant was an elite 33 year-old male chess player ranked among the 300 best chess players in the world. Thus, cortical arousal by critical flicker fusion threshold, electroencephalogram by the theta Fz/alpha Pz ratio and autonomic modulation by heart rate variability were analyzed...

BACKGROUND: Research exploring the effects of physical exercise in auto-immune myasthenia gravis (MG) is scarce. The few existing studies present methodological shortcomings limiting the conclusions and generalisability of results. It is hypothesised that exercise could have positive physical, psychological as well as immunomodulatory effects and may be a beneficial addition to current pharmacological management of this chronic disease. The aim of this study is to evaluate the benefits on perceived quality of life (QOL) and physical fitness of a home-based physical exercise program compared to usual care, for patients with stabilised, generalised auto-immune MG...

The European Higher Education Area (EHEA) is an opportunity to redesign medical education. Academic training is now focused on acquiring not only knowledge, but also those competencies critical to face complex professional scenarios. Together with re-evaluating traditional teaching methods, EHEA has forced a technological shift in the way we teach. By critically assessing the impact of novel teaching methodologies, we can better define biomedical education demands. Here, we address this question on a sample of medical students instructed in basic subjects along the first two academic courses...

Heme oxygenase (HO) is an essential, rate-limiting protein which catalyzes the breakdown of heme to iron, carbon monoxide (CO), and biliverdin. The alpha methene bridge of the heme is eliminated as CO which can be measured as blood carboxyhemoglobin (COHb). Using blood concentrations of COHb as a measure reflecting HO activity, we tested the postulate that the activity of HO changes with exercise. Ten healthy, nonsmoking volunteers (5 females and 5 males with a mean age ± standard deviation of 25.7 ± 3...

BACKGROUND: Automated systems are available in various application areas all over the world for the purpose of reducing workload and increasing safety. However, such support systems that would aid caregivers are still lacking in the medical sector. With respect to workload and safety, especially, the intensive care unit appears to be an important and challenging application field. Whereas many closed-loop subsystems for single applications already exist, no comprehensive system covering multiple therapeutic aspects and interactions is available yet...

PURPOSE: Worldwide ophthalmologists are challenged by the rapid rise in the prevalence of diabetes. Diabetic retinopathy (DR) is the most common complication in diabetes, and possible consequences range from mild visual impairment to blindness. Repetitive screening for DR is cost-effective, but it is also a costly and strenuous affair. Several studies have examined the application of automated image analysis to solve this problem. Large populations are needed to assess the efficacy of such programs, and a standardized and rigorous methodology is important to give an indication of system performance in actual clinical settings...

This study aimed to identify the effects of playing formations on tactical behaviour and external workload during football small-sided games. Twenty-three semi-professional footballers integrated three different playing formations in a 7-a-side small-sided game, according to their specific player positions: team 4:3:0 (4 defenders, 3 midfielders); team 4:1:2 (4 defenders, 1 midfielder, 2 forwards); and team 0:4:3 (4 midfielders, 3 forwards). Based on players' movement trajectories, the following individual and collective tactical variables were calculated: total distance covered and distance covered while walking, jogging, running and sprinting, distance from each player to both own and opponent's team centroid (Dist CG and Dist OPP CG, respectively), individual area, team length, team width and surface area...

In recent years, significant workload, high acuity, and complexity of emergency general surgery conditions have led hospitals to replace the traditional on-call model with dedicated acute care surgery (ACS) service models. A systematic search of Ovid, EMBASE, and MEDLINE was undertaken to examine the impact of ACS services on health-care delivery processes and cost, education, and provider satisfaction. From 1827 papers, reviewers identified 22 studies that met inclusion criteria and subsequently used The Evidence-Based Practice for Improving Quality method and Newcastle-Ottawa Scale to score quality and level of evidence...

"Organ reserve" refers to the ability of an organ to successfully return to its original physiological state following repeated episodes of stress. Clinical evidence shows that organ reserve correlates with the ability of older adults to cope with an added workload or stress, suggesting a role in the process of aging. Although organ reserve is well documented clinically, it is not clearly defined at the molecular level. Interestingly, several metabolic pathways exhibit excess metabolic capacities (e.g., bioenergetics pathway, antioxidants system, plasticity)...

BACKGROUND: The implementation of telemonitoring at scale has been less successful than anticipated, often hindered by clinicians' perceived increase in workload. One important factor has been the lack of integration of patient generated data (PGD) with the electronic medical record (EMR). Clinicians have had problems accessing PGD on telehealth systems especially in patient consultations in primary care. OBJECTIVE: To design a method to produce a report of PGD that is available to clinicians through their routine EMR system...

As the volume and complexity of imaging in the UK continues to rise, there is pressure on radiologists to spend increasing lengths of time reporting to cope with the growing workload. However, there is limited guidance for radiologists about structuring the working day to achieve the necessary balance between satisfactory reporting volume and maintaining quality and safety. We surveyed 86 Neuroradiologists (receiving 59 responses), regarding time spent reporting, frequency and duration of work breaks, and break activities...

The handover of large numbers of medical patients, during on call periods when staffing levels are reduced, is a challenge for all acute medical services. At the Royal Cornwall Hospital, a large district general hospital, we identified that foundation doctors were reviewing medical inpatients during weekend on call periods with limited written handover information. We chose to address this problem by developing an intervention, a weekend handover sticker, and piloting it. We used the review of documentation to measure improvement and feedback from users to assess the processes involved...
