This study investigated factors related to competency by assessing the mental readiness among highly recognized frontline workers in homelessness services (FWHSs) by means of self-completed questionnaires. A total of 35 highly respected FWHSs in Ottawa, Canada were identified by their peers and supervisors as “exceptional” for various specialty areas: addictions, mental health, hoarding, trauma and post-traumatic stress disorder (PTSD). An Operational Readiness Framework was used to examine how FWHSs perform at their best in challenging situations. A series of questionnaires were completed at a Think Tank to determine their mental readiness before, during and after challenging situations. Quantitative and qualitative analyses of mental readiness were performed to prioritize identified challenges. The study findings were then compared to the “Wheel of Excellence” based on results from elite athletes and other high performers such as surgeons, police, and air traffic controllers. The analysis revealed that mental readiness is required to achieve peak performance in addressing the challenges of homelessness. The balance between readiness (physical, technical and mental) and performance contributed to their competency and resiliency. Common elements of success were found: commitment, self-belief, positive imagery, mental preparation, full focus, distraction control and constructive evaluation. This investigation confirmed many similarities in mental readiness practices engaged by excellent FWHSs and other top professionals. This study offered, for the first time, a comprehensive understanding of specific high-performance readiness practices through a streetwise, frontline-worker perspective. Practical recommendations for training and assessment were provided relevant to excellence in homelessness services.

The publication of DSM-III introduced the diagnosis Post-Traumatic Stress Disorder (PTSD), thus providing, for the first time, a framework for studying the consequences of extremely stressful events. Previously, traumatic neuroses had attracted a wide variety of labels – as wide as the experiences that produced them. Competing explanations in psychological and biological terms have characterised the approach to these disorders, and social and legal issues have added to the confusion. In recent years, psychosocial issues have tended to dominate the literature in relation to PTSD. While acknowledging the importance of such phenomenological and psychosocial approaches, this paper seeks to redress the balance by focusing on a biological perspective.

We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank.

IntroductionA trauma is an uncommon experience of violence in which the physical and psychological integrity of an individual or group has been threatened. Intentional violence in general and terrorist attacks in particular are a perfect example of this. It turns out that during the year 2015 Tunisia was shaken by a series of terrorist attacks as sudden as violent. What impact would these actions have on the profile of consultants at the Razi hospital?MethodsA retrospective and descriptive study of the consultants between January 1, 2015 and December 31, 2015, while determining the socio-demographic, clinical and therapeutic profile of the consultants for the first time at the outpatient clinic of the Razi psychiatric hospital, and indicating the different changes during the month following each attack; Bardo 18 March, Sousse 26 June and Mohamed V 24 November.ResultsOur study pointed to an increase in the number of consultants at the hospital (31%) and outpatient (128%) levels during the year 2015, without increasing the number of consultants New consultants. The new consultants are younger with a strengthening of the female predominance (56.8). In the months following the attacks from the same period of the previous year, we found that diagnoses of acute and post-traumatic stress disorders (151%) and (93%) increased in percentage.ConclusionThe impact of terrorist attacks is harmful to people directly exposed but also to vulnerable people. It imposes the necessity of a preventive activity involving multidisciplinary interventions in order to develop the concept of resilience.Disclosure of interestThe authors have not supplied their declaration of competing interest.

AbstractPost-traumatic stress disorder (PTSD) is characterized by complex, heterogeneous symptomology, thus detection outside traditional clinical contexts is difficult. Fortunately, advances in mobile technology, passive sensing, and analytics offer promising avenues for research and development. The present study examined the ability to utilize Global Positioning System (GPS) data, derived passively from a smartphone across seven days, to detect PTSD diagnostic status among a cohort (N = 185) of high-risk, previously traumatized women. Using daily time spent away and maximum distance traveled from home as a basis for model feature engineering, the results suggested that diagnostic group status can be predicted out-of-fold with high performance (AUC = 0.816, balanced sensitivity = 0.743, balanced specificity = 0.8, balanced accuracy = 0.771). Results further implicate the potential utility of GPS information as a digital biomarker of the PTSD behavioral repertoire. Future PTSD research will benefit from application of GPS data within larger, more diverse populations.

Competencies required for dentistry go far beyond the academic or scientific spheres. They incorporate important mental readiness concepts at its core with an appropriate balance of operational readiness (i.e., technical, physical, mental readiness). The aim of this exploratory study was to investigate the importance of mental readiness for optimal performance in the daily challenges faced by dentists using an Operational Readiness Framework. One-on-one interviews were conducted with a select group of seasoned dentists to determine their mental readiness before, during and after successfully performing in challenging situations. Quantitative and qualitative analyses of mental readiness were applied. Study findings were compared with a Wheel of Excellence based on results from other high-performance domains such as surgery, policing, social services and Olympic athletics. The analysis revealed that specific mental practices are required to achieve peak performance, and the balance between physical, technical and mental readiness underpins these dentists’ competency. Common elements of success were found—commitment, confidence, visualization, mental preparation, focus, distraction control, and evaluation and coping. This exploration confirmed many similarities in mental readiness practices engaged across high-risk professions. Universities, clinics and hospitals are looking for innovative ways to build teamwork and capacity through inter-professional collaboration. Results from these case studies warrant further investigation and may be significant enough to stimulate innovative curriculum design. Based on these preliminary dentistry findings, three training/evaluation tools from other professions in population health were adapted to demonstrate future application.

Clustering is an important task in data mining that has become more challenging due to the ever-increasing size of available datasets. To cope with these big data scenarios, a high-performance clustering approach is required. Sparse grid clustering is a density-based clustering method that uses a sparse grid density estimation as its central building block. The underlying density estimation approach enables the detection of clusters with non-convex shapes and without a predetermined number of clusters. In this work, we introduce a new distributed and performance-portable variant of the sparse grid clustering algorithm that is suited for big data settings. Our compute kernels were implemented in OpenCL to enable portability across a wide range of architectures. For distributed environments, we added a manager-worker scheme that was implemented using MPI. In experiments on two supercomputers, Piz Daint and Hazel Hen, with up to 100 million data points in a 10-dimensional dataset, we show the performance and scalability of our approach. The dataset with 100 million data points was clustered in 1198s using 128 nodes of Piz Daint. This translates to an overall performance of 352TFLOPS. On the node-level, we provide results for two GPUs, Nvidia's Tesla P100 and the AMD FirePro W8100, and one processor-based platform that uses Intel Xeon E5-2680v3 processors. In these experiments, we achieved between 43% and 66% of the peak performance across all compute kernels and devices, demonstrating the performance portability of our approach.

The problems of scheduling a single parallel job across a large-scale distributed system are well known and surprisingly difficult to solve. In addition, because of the issues involved in distributed submission, such as co-reserving resources, and managing accounts and certificates simultaneously on multiple machines, etc., the vast number of high-performance computing (HPC) application users have been happy to remain restricted to submitting jobs to single machines. Meanwhile, the need to simulate larger and more complex physical systems continues to grow, with a concomitant increase in the number of cores required to solve the resulting scientific problems. One might reduce the demand on load per machine, and eventually the wait-time in queue, by decomposing the problem to use two resources in such circumstances, even though there might be a reduction in the peak performance. This motivates a question. Can otherwise monolithic jobs running on single resources be distributed over more than one machine such that there is an overall reduction in the time-to-solution? In this paper, we briefly discuss the development and performance of a parallel molecular dynamics code and its generalization to work on multiple distributed machines (using MPICH-G2). We benchmark and validate the performance of our simulations over multiple input datasets of varying sizes. The primary aim of this work, however, is to show that the time-to-solution can be reduced by sacrificing some peak performance and distributing over multiple machines.

The Relationship

The relationship between skeletal muscle fatigue and morpho-functional alterations in the myocardium was analyzed for the first time in Wistar male rats exposed to chronic stress. Post traumatic stress disorder (PTSD) was associated with signs of increased oxidative stress, which apparently induced the changes in cardiomyocyte structural components and the acceleration of skeletal and muscular fatigue.
