Rehabilitation is a vital component of stroke recovery, but inpatient stroke rehabilitation programs can struggle to meet the recommended hours of therapy per day outlined by the Canadian Stroke Best Practices and American Heart Association. Mobile applications (apps) are an emerging technology which may help bridge this deficit, however this area is understudied. The purpose of this study is to review the effect of mobile apps for stroke rehabilitation on stroke impairments and functional outcomes. Specifically, this paper will delve into the impact of varying mobile app types on stroke rehabilitation. Methods This systematic review included 29 studies: 11 randomized control trials and 18 quasi-experimental studies. Data extrapolation mapped 5 mobile app types (therapy apps, education apps, rehab videos, reminders, and a combination of rehab videos with remin...

Recent developments in deep neural networks (DNNs) for survival analysis show the superiority of these models in comparison with other well-known models in survival analysis applications. Ensuring the reliability and explainability of deep survival models deployed in healthcare is a necessity. Since DNN models often behave like a black box, their predictions might not be easily trusted by clinicians, especially when predictions are contrary to a physician's opinion. A deep survival model that explains and justifies its decision-making process could potentially gain the trust of clinicians. In this research, we propose the reverse survival model (RSM) framework that provides detailed insights into the 1

In chronic musculoskeletal related pain conditions, a decreased NFR threshold has been suggested as a possible recognition evidence for central sensitization that may cause alteration of central nervous system processing (CNSP). OBJECTIVE To systematically review reported comparisons of the NFR threshold in chronic pain patients and healthy individuals. METHODS Electronic databases covering studies published between January 1990-December 2019 were systematically searched. After application of exclusion criteria 20 studies including 28 trials were included in this review. For meta-analysis, we utilized a random-effects model and funnel plot for publication bias. This research was registered at PROSPERO (CRD42019140354). RESULTS Compared to healthy controls, standardized mean differences in NFR threshold were significantly lower in the total sample of chronic pain patients. Subgroup analysis indicated a homogenous decreased NFR threshold in studies reporting fibromyalgia, chronic pain, and joint pain while heterogeneity existed in other included pain conditions. CONCLUSION A lower NFR threshold in patients suffering from chronic pain conditions may imply hyperexcitability in central nervous system processing. As a preliminary study, the findings would act as a basis for developing a methodology assisting current clinical practices.

Design: Prospective cohort study. Setting: Community. Participants: Individuals (NZ26; 6 female, aged 58.9AE18.2y) with motor incomplete SCI/D (American Spinal Injury Association Impairment Scale rating C [nZ5] or D [nZ21]) participated. Participants were 7.5AE9.1 years post injury. Seventeen participants experienced traumatic causes of spinal cord injury. Main Outcome Measures: Participants completed laboratory-based and clinical measures of postural control, gait speed, balance self-efficacy, and lower extremity strength, as well as proprioception and cutaneous pressure sensitivity. Participants were then followed for up to 1 year to track falls using a survey. The survey queried the circumstances and consequences of each fall. If a participant's number of falls equaled or exceeded the median number of falls experience by all participants, they were classified a faller.

METHODS A prospective longitudinal study was conducted to test the effects of a structured educational curriculum in three CR programs in Canada. Participants completed surveys pre-, post-CR and 6 mo post-discharge to assess knowledge, heart-healthy food intake, self-efficacy, and health literacy. Exercise behavior was measured by number of steps/d using a pedometer. RESULTS One hundred twenty participants completed the final survey. Increases in disease-related knowledge and self-efficacy, as well as behavior changes (increases in exercise and heart-healthy food intake), were achieved in comprehensive CR and sustained 6 mo post-program. Exercise maintenance was predicted by changes in heart-healthy food intake, self-efficacy, health literacy, and exercise-related knowledge. CONCLUSIONS In this three-site study focusing on patient education for CR patients in Canada, the benefits of an education intervention in maintaining knowledge, exercise, healthy food intake, and self-efficacy were supported.

The objective of this study was to develop and validate the DiAbeTes Education Questionnaire (DATE-Q) to measure knowledge among diabetes and prediabetes patients attending cardiac rehabilitation (CR). METHODS Based on patient information needs, other validated tools and diabetes education standards and current practices, experts developed 20 items to comprise the first version of the DATE-Q. To establish content validity, they were reviewed by an expert panel (n = 12) and patients. Refined items were psychometrically tested in 84 diabetes and prediabetes patients attending CR. The internal consistency was assessed via regularized factor analysis and Cronbach α, and criterion validity with regard to patient education and family income. For interpretability analysis, the minimal clinically important difference (MCID) was estimated using distribution- and anchor-based methods. RESULTS All items were appropriate for administration in this population according to experts and patients. Three factors were extracted and were generally internally consistent and well defined by the items. Criterion validity was supported by significant differences in mean scores by family income (P < .05). Results showed that increases in knowledge can moderately increase mean steps/d and peak oxygen uptake, with an MCID of 2.13. CONCLUSIONS This study demonstrated preliminary validity of the DATE-Q. Future research is needed to assess other measurement properties to confirm the applicability of this tool in clinical and research settings.

DESIGN Cross-sectional telephone survey study. SETTING Tertiary SCI rehabilitation centre. Ontario, Canada. PARTICIPANTS Community-dwelling adults with chronic SCI/D (N=170). INTERVENTION Not applicable MAIN OUTCOME MEASURES: The main outcome measures were the Short-Form 36 (SF-36) to assess health and the Life Satisfaction-11 (LiSAT-11) to assess life satisfaction. RESULTS A hierarchical regression model predicting physical health accounted for 24% (p<.001) of the variance. The only social network variable to significantly contribute to the model was having a higher proportion of family members living in one's household (p<.05). A model predicting mental health accounted for 44% (p<.001) of the variance, with having a higher proportion of family members living in one's household (p<.05) and lower feelings of loneliness (p<.001) being associated with better mental health. Finally, the model predicting life satisfaction accounted for 62% (p<.001) of the variance, with lower greater levels of social network intimacy (p<.01) and lower feelings of loneliness (p<.001) being significant predictors. CONCLUSIONS These findings highlight the importance of having access to family members in one's home for better physical and mental health post-SCI/D as well as the negative association between loneliness and mental health and life satisfaction. There is a need for approaches to ensure that people with SCI/D in the community feel supported to mitigate feelings of loneliness in order to optimize their health and wellbeing.

Rodents can act as a major source of infection for humans and animals. The disease has a global distribution, mainly in humid, tropical and subtropical regions. In Iran the disease is endemic in some parts of the north of the country. Methods & Materials: This study was conducted to investigate the existenceand important ofLeptospira species in rodent of North Khorasan Province, Iran. For this study, thirty six rodents were trapped alive. Blood samples were taken and serum were separated and kept in freezer for serological investigation. The seropositiveserovars were identified and the antibody titers were measured bythe standard microscopic agglutination test(MAT), using a panel of 8 strains of live Leptospira species as antigens. Serial dilutions (1/100 to 1/1600) of serum were used. Results: The result of this study showed that 12 samples (33%) had a positive reaction against one or twosarovars. In general, 5 samples had a posistive reaction with serovar Pomona, 3 samples with Australis, 2 samples with Taraseviand 2 samples with Icterohaemorrhagiae. Theresults also showed that the most prevalent leptospiraserovar was Pomona (14%) and the most common titer was 1/100 (10 samples) and thehighest titer was 1/200 (2 samples). Conclusion: This study of leptospirosis is the first one in rodents in this region and it showed that Leptospirosis is prevalent in rodents in North Khorasan Province. However, further study is required to determine the importance of rodents in circulating the Leptospires into the animal and human populations.

The model is designed based on the sequence-to-sequence (Seq2Seq) architecture, therefore we name it Survival Seq2Seq. The ﬁrst recurrent neural network (RNN) layer of the encoder of our model is made up of Gated Recurrent Unit with Decay (GRU-D) cells. These cells have the ability to effectively impute not-missing-at-random values of longitudinal datasets with very high missing rates, such as electronic health records (EHRs). The decoder of Survival Seq2Seq generates a probability distribution function (PDF) for each competing risk without assuming any prior distribution for the risks. Taking advantage of RNN cells, the decoder is able to generate smooth and virtually spike-free PDFs. This is beyond the capability of existing non-parametric deep models for survival analysis. Training results on synthetic and medical datasets prov...

To date, there is no data on the seroprevalence of leptospirosis among humans in this province. This study was performed to determine the prevalence of human leptospiral infection among people with different occupations. The study was conducted in urban and rural areas of the province. Among the serum samples collected from 278 subjects, 3 (1.1%) showed positive reaction with titer of 1:100 by the microscopic agglutination test (MAT). Positive reactions were detected against Leptospira interrogans Canicola and L. interrogans icterohemorrhagic and all these samples were from livestock farmers (n ¼ 3/106, 2.7%). The current study revealed that, though Leptospira infection is low in North Khorasan province, regular monitoring of the livestock and the farmers are important.
