Cross-cultural Adaptation and Validation of the Arabic version of Stroke Self-Efficacy Questionnaire for Patients with Stroke

BACKGROUND

Self-efficacy has an important impact on rehabilitation outcomes in stroke. The Stroke Self-Efficacy Questionnaire assesses performance in daily functional activities and self-management following a stroke.

PURPOSE

To translate and cross-culturally adapt the Stroke Self-Efficacy Questionnaire (SSEQ) into the Arabic language and to assess its psychometric properties among patients with stroke.

METHODS

SSEQ was translated into Modern Arabic and then translated back into English. An expert review panel produced a pre-final version of SSEQ-AR, which was followed by a pilot test with a sample of 15 patients with stroke. The psychometric properties of the final version of the SSEQ-AR were evaluated in 135 patients with stroke.

DATA ANALYSIS

Cronbach's alpha and ICC were calculated to describe the internal consistency and test-retest reliability, respectively. Short-Form Survey (SF-12) physical and mental subscales and Fall Efficacy Scale International were used to determine the construct validity.

RESULTS

The total score of the SSEQ-AR and subscales showed a strong to very strong (ICC2,1 0.89-0.92), and acceptable internal consistency for two subscales (Cronbach's alpha = 0.81 to 0.94) and total (Cronbach's alpha = 0.93). The SSEQ-AR subscales showed a good correlation with physical component subscales of SF-12 (r = 0.64-0.72) and excellent correlation with FES-I in total (r = 0.82) and with subscales (r = 0.75-0.79).

CONCLUSION

This study shows that SSEQ-AR is a reliable and valid instrument that assesses the level of self-efficacy for patients with stroke in Arabic-speaking countries.

Artificial Intelligence machine learning and conventional physical therapy for upper limb outcome in patients with stroke: a systematic review and meta-analysis

OBJECTIVE

The goal of this study was to compare the effect of different artificial intelligence (AI) machine learning and conventional therapy (CT) on upper limb impairments in patients with stroke.

MATERIALS AND METHODS

PubMed, PubMed Central, Google Scholar, MEDLINE, Cochrane Library, Web of Science, Research Gate, and Wiley Online Library were searched. Descriptive statistics about variables were reported to calculate standardized mean differences in outcomes of motor control (the primary outcome), functional independence, upper extremity performance, and muscle tone. The Physiotherapy Evidence Database (PEDro) Scale was used to assess qualitative papers. The primary outcomes of AI and CT have been included in the meta-analyses.

RESULTS

Ten papers with a total of 481 stroke patients were included and upper limb rehabilitation, upper limb functioning, and basic manual dexterity were examined. The heterogeneity test of the whole included measures (I2=45%) was medium. There were significant differences between the included measures (p-value=0.03) with a total SMD of 0.10 [0.01, 0.19]. According to the test for subgroup difference, it was found that there was a highly significant difference between the subgroups of the included measures (p-value=0.01) and the heterogeneity test (I2=59.8%).

CONCLUSIONS

AI is a feasible and safe method in post-stroke rehabilitation and improves upper-extremity function compared to CT. Significant AI post-treatment effects on upper-limb impairments have been observed. The findings showed that higher-quality evidence was detected in six assessment scales. However, a lower quality of evidence was detected in other scales. This indicated large or very large and consistent estimates of the treatment effects, and researchers were confident about the results. Therefore, the included observational studies are likely to provide an overestimate of the true effect.

Incidence of Guillain-Barré Syndrome post COVID-19: a systematic review of case reports and case series

OBJECTIVE

The purpose of this systematic review was to study the incidence, risk factors and patients subjected to Guillain-Barré syndrome (GBS) after COVID-19.

MATERIALS AND METHODS

For qualitative assessment and assessing the methodological quality, the Cochrane Handbook for Systematic Reviews of Interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) checklist were utilized. Data from PubMed, Cochrane, Embase, CINAHIL, Medline, ResearchGate, and Scopus were searched. The relevant studies involved patients with confirmed COVID-19 diagnosis by RT-PCR, and GBS diagnosis based on typical clinical symptoms and/or confirmatory diagnostic results. A total of 12 English relevant articles (6 papers were case reports and 8 were case series with a total of 32 patients) published in a peer-reviewed journal from 2019 to 2021 were included. Following the review methodology, two independent raters were responsible for retrieving, extracting and checking for data eligibility. Demographic characteristics are presented as frequencies and percentages. Based on distribution of values, continuous data were expressed as median and interquartile range (IQR).

RESULTS

Out of 32 patients, 26 patients reported neurological symptoms, 6 cases went unnoticed, 7 cases showed involvement of the cranial nerves, 12 cases did not, and 13 cases went unreported.

CONCLUSIONS

It is too early to draw any conclusions concerning a potential relationship between SARS-CoV-2 infection and GBS. More large-scale observational studies are required to understand the pathogenesis of SARS-CoV-2-associated GBS and to demonstrate a definite causal relationship between GBS and SARS-CoV-2 infection.

Correlation of serum hepatitis C virus RNA titre with aminotransferases and liver histopathological findings in HCV-seropositive cases with end-stage chronic liver disease

The quantity of circulating hepatitis C virus (HCV) RNA, aminotransferases and the degree of liver cell injury in relation to HCV serotype have not been fully studied. In this work, we estimated the HCV RNA titre in serum and correlated the findings with levels of aminotransferases, gamma glutamyltransferase (GGT), and liver histopathological changes and with HCV serotype. HCV RNA was found in 22 out of 30 HCV-seropositive cases included in this study (73. 3%) and serotype 4 represented 90.9% (20/22). Levels of aminotransferases and GGT correlated with the levels of serum HCV RNA. Noticeably, GGT showed the highest positive correlation with the level of HCV RNA. Liver histopathological findings of 15 patients showed that eight had hepatocellular carcinoma and seven had cirrhosis. There was no significant difference between these two groups regarding levels of enzymes or serum HCV RNA titre.

Comparison of amplicor and 32-kilodalton PCR for detection of Mycobacterium tuberculosis from sputum specimens

The commercial PCR test Amplicor was compared with the 32-kDa PCR for detection of Mycobacterium tuberculosis from 76 sputum specimens from Egyptian patients. Both tests performed with rather equal efficacy (resolved sensitivity of 88.9% for both tests; specificity of 98.0% for Amplicor and 93.9% for 32-kDa PCR). PCR was found to be useful in detection of auramine fluorescent stain-positive, culture-negative specimens.
