A clinical study was made on depressive state following stroke using stroke patients in the chronic stage. There were 118 stroke patients in the present study and 25 patients (21.2%) satisfied the diagnostic criteria for major depressive syndrome of the Diagnostic and Statistical Manual of Mental Disorders, Third Edition Revised (DSM-III-R). As for dispositional, social, and somatic factors, a tendency was observed for depressive state to develop at a high frequency among patients with a past history of mental disorder prior to development of stroke, patients residing in suburban area, patients engaged in domestic and agricultural work, and patients with a frequent history of physical disorders. A tendency was observed for depressive state to develop at a high frequency among patients showing B type in YG test and patients presenting laterality in electroencephalography. Among the 49 right stroke patients, depressive state was observed in 10 cases (20.4%), while among the 43 left stroke patients, depressive state was seen in 10 cases (23.2%) with the incidence of depressive state showing no difference by hemisphere stroke. Study of the clinical characteristics of depressive state by hemisphere stroke with the use of symptom items of Zung scale and Hamilton scale showed that patients in depressive state with right hemisphere stroke had high values in symptom items considered close to the essence of endogenous depression such as depressed mood, suicide, diurnal variation, loss of weight, and paranoid symptoms, while patients in depressive state with left hemisphere stroke had high values in symptom items having a nuance of so-called neurotic depression such as psychic anxiety, hypochondriasis, and fatigue. Comparison with endogenous depression patients indicated that right stroke patients rather than left stroke patients showed a clinical picture suggestive of endogenous depression. Antidepressant was effective in 71.4% of the cases, but no difference in effectiveness could be observed by hemisphere stroke. In stroke patients in the chronic stage the incidence of clinical depressive state was higher than 20%, and involved in its onset were not only brain organ lesions but also dispositional, social, and somatic factors and integration dysfunction in the emotional activity of the left and right hemisphere functions. As for the clinical picture, a picture considered close to endogenous depression was observed in right stroke patients, while that considered close to so-called neurotic depression was seen in left stroke patients. The therapeutic effect of antidepressant was almost equivalent to that for endogenous depression.

Muscle fatigue is considered as one of the major risk factors for developing musculoskeletal disorders. The aim of this project was to select an adequate fatigue assessment model for an implementation in Dassault Systemes digital human modeling software. A review of existing MET models has been done resulting in a decision to use the extended Ma's model (2010). In this project, only shoulder and elbow joints have been tested and more subjects will be necessary for further validation. The model has been compared to several endurance time (ET) static studies. Two dynamic experiments were also performed by two different subjects. The results showed that because of the inter-individual variability, a simple prediction curve or value, can't well predict individual measured ET (or task failure). There is a need for a chart representation which also shows standard deviation (SD) range. Considering the SD range, the results were included in the prediction. Thus, this range may help the human factors expert to nuance the prediction results while considering environment factors and some realities specific to the industry.

SARS-CoV-2 is the causative virus responsible for the COVID-19 pandemic. This pandemic has necessitated that all professional and elite sport is either suspended, postponed or cancelled altogether to minimise the risk of viral spread. As infection rates drop and quarantine restrictions are lifted, the question how athletes can safely resume competitive sport is being asked. Given the rapidly evolving knowledge base about the virus and changing governmental and public health recommendations, a precise answer to this question is fraught with complexity and nuance. Without robust data to inform policy, return-to-play (RTP) decisions are especially difficult for elite athletes on the suspicion that the COVID-19 virus could result in significant cardiorespiratory compromise in a minority of afflicted athletes. There are now consistent reports of athletes reporting persistent and residual symptoms many weeks to months after initial COVID-19 infection. These symptoms include cough, tachycardia and extreme fatigue. To support safe RTP, we provide sport and exercise medicine physicians with practical recommendations on how to exclude cardiorespiratory complications of COVID-19 in elite athletes who place high demand on their cardiorespiratory system. As new evidence emerges, guidance for a safe RTP should be updated.

(1) Background: The five rights of clinical decision support (CDS) are a well-known framework for planning the nuances of CDS, but recent advancements have given us more options to modify the format of the alert. One-size-fits-all assessments fail to capture the nuance of different BestPractice Advisory (BPA) formats. To demonstrate a tailored evaluation methodology, we assessed a BPA after implementation of Storyboard for changes in alert fatigue, behavior influence, and task completion; (2) Methods: Data from 19 weeks before and after implementation were used to evaluate differences in each domain. Individual clinics were evaluated for task completion and compared for changes pre- and post-redesign; (3) Results: The change in format was correlated with an increase in alert fatigue, a decrease in erroneous free text answers, and worsened task completion at a system level. At a local level, however, 14% of clinics had improved task completion; (4) Conclusions: While the change in BPA format was correlated with decreased performance, the changes may have been driven primarily by the COVID-19 pandemic. The framework and metrics proposed can be used in future studies to assess the impact of new CDS formats. Although the changes in this study seemed undesirable in aggregate, some positive changes were observed at the level of individual clinics. Personalized implementations of CDS tools based on local need should be considered.
