Background:The aim of this study was to investigate the direct and indirect effects of selfmanagement on Nutrition Behavior (NB) with the mediating role of Psychological Capital (PC) in People with Multiple Sclerosis (PwMS) in Gilan province. Methods: We studied PwMS in Guilan MS Society (GMSS) in a cross-sectional design research in 2019. We invited 275 PwMS to participate in the study either through convenience sampling method. Data collection tool consisted of questions about demographic characteristics of participants, a revised form of Multiple Sclerosis Self-Management Scale (MSSM-R), Psychological Capital Questionnaire (PCQ), and Health-Promoting Lifestyle Profile II (HPLP-II). Data were analyzed using Pearson correlation coefficient and Structural Equation Modeling (SEM) in SPSS 19.0 and Amos 18.0 statistical software. Results: The results showed that nutrition has a significant positive correlation with selfmanagement (r = 0.342), self-efficacy (r = 0.211), optimism (r =0.208), hope (r = 0.316), resiliency (r = 0.237), and PC (r = 0.287) (P-value < 0.001). Additionally, the results showed that the direct and indirect effect of self-management on nutrition was significant and the proposed model had a good data fitting. The VAF index showed that 18% of the total effect of selfmanagement on nutrition behavior is indirectly explained by the mediating variable of psychological capital. Conclusion: Self-management and PC were associated with NB in PwMS. The results of this study support the importance of these factors in health-promoting behaviors with regard to NB and the proposed model can be a suitable option in health care and nursing provided that, the fit of this model is investigated in future research and other provinces.
Background: Stroke is one of the most important causes of disability-adjusted life years lost. Low socioeconomic status is associated with increased stroke-related morbidity and mortality. Objective: This study aimed to investigate in-hospital mortality rate caused by severe cases of ischemic and hemorrhagic stroke and its relationship with patients’ socioeconomic status. Materials and Methods: This comparative analytical study with a cross-sectional design was conducted from April 2018 to March 2019 on 384 patients diagnosed with severe stroke admitted to the neurology department of Poursina Hospital in Rasht, Iran, who were selected using a purposive sampling method. They completed a demographic checklist and the Socio-Economic Status Questionnaire. Data analysis was carried out in SPSS V. 21 software. Results: It was reported a stroke death rate of 59.9%, of which 75.7% occurred in the hospital. Stroke-related mortality rate had a significant relationship with age (P=0.021), gender (P=0.047), not owning a home (P<0.001) and socioeconomic status (P<0.001). Conclusion: Some demographic factors including old age, male gender, not owning a home, and low socioeconomic status increase the risk of stroke-related mortality.
Background and Aim: The present study aimed to use the median nerve Compound Muscle Action Potential (CMAP) amplitude by stimulation at the palm instead of Abductor Pollicis Brevis (APB) needle Electromyography (EMG) for determining axonal loss in patients with Carpal Tunnel Syndrome (CTS). Methods and Materials/Patients: This study was performed on 180 patients with CTS referred to the Electrodiagnostic (EDX) Center, Poursina Hospital, Guilan Province, Iran, in 2018-19. In this study, the APB needle EMG diagnostic test was used as the gold standard, and median nerve CMAP amplitude with stimulation at the palm and wrist were used to compare the two nerve stimulation tests. Results: All of the cases with abnormal amplitude loss detected by median nerve stimulation at the palm also had an axonal loss in the needle EMG of APB. So this test could be a good indicator of axonal loss if there is an abnormality (sensitivity: 73%, specificity: 100%). The results with wrist stimulation were not as accurate as of the palm stimulation, and some cases with decreased CMAP amplitude of median nerve had normal needle EMG of APB muscle (sensitivity: 86.6%, specificity: 94.9%). Conclusion: In cases with CTS, the abnormally decreased amplitude of the median nerve detected by stimulation at the palm could be a good indicator of axonal loss.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
