Prospective evaluation of modified Cincinnati Prehospital Stroke Severity Scale for identifying large vessel occlusion

OBJECTIVE

To develop a novel, straightforward diagnostic scale for predicting large vessel occlusion (LVO) and anterior circulation LVO (ALVO) in the emergency setting, evaluating its validity against existing scales.

METHODS

We prospectively enrolled patients with suspected stroke presenting consecutively at the National Comprehensive Stroke Centre's emergency department between February 20, 2022, and November 11, 2022. Emergency physicians assessed each patient using the modified Cincinnati Prehospital Stroke Severity Scale (mCPSSS) and the National Institutes of Health Stroke Scale (NIHSS). The study analyzed the mCPSSS and other prevalent stroke scales to evaluate their efficacy in detecting LVO and ALVO, employing receiver operating characteristic curve (ROC) analysis and area under the curve (AUC) statistics to assess the scales' sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall accuracy.

RESULTS

A total of 383 patients with suspected stroke were included in this study. The performance in identifying LVO in the emergency setting was greatest for mCPSSS ≥ 2 with a sensitivity of 0.802 and specificity of 0.770, PPV of 0.644, NPV of 0.882, and accuracy of 0.781. mCPSSS ≥ 2 was 0.766 sensitive, 0.733 specific, PPV of 0.564, NPV of 0.886, and accuracy of 0.749 in predicting ALVO. The mCPSSS identified LVO and ALVO with an optimal cut-off value of 2, exhibiting AUC superior to those of other widely used stroke scales, with AUC values of 0.824 for LVO and 0.790 for ALVO.

CONCLUSION

The mCPSSS could serve as an effective and straightforward scale for identifying LVOs in emergency settings.

Assessment of knowledge and awareness of stroke among Arabic speaking adults: unveiling the current landscape in seven countries through the first international representative study

Introduction

While several studies have examined stroke public knowledge and awareness in individual countries within the Middle East and North Africa (MENA) region, none have provided a comprehensive cross-country assessment.

Purpose

To assess public stroke knowledge and awareness among Arabic-speaking adults in seven MENA countries and identify associated factors.

Materials and methods

An online cross-sectional survey was self-administered by the public population in Iraq, Lebanon, Sudan, Jordan, United Arab Emirates, Syria, and Saudi Arabia (April 2021-2023). Associations of stroke risk factors, early symptoms, and consequences with socio-demographics and medical history were analyzed using logistic regression models.

Results

Of 4,090 participants (58.3% females), 42.9% identified four out of five correct answers related to general stroke knowledge. Only 25.2% identified all stroke risk factors, 24.7% recognized all symptoms, and 37.5% knew all possible consequences. Results show consistent pattern of high identification for at least one risk factor and consequences across all countries (96.3 to 99.8% and 86.2 to 100%, respectively), with varying levels of early symptom identification (56.8 to 97.9%). Females were more likely to identify a stroke risk factor, symptom, and consequence compared to males (OR = 2.525, 2.474, and 2.302, respectively, p < 0.001). Employed, urban residents, and those with higher education demonstrated better stroke awareness.

Conclusion

The sample showed variable levels of stroke knowledge among the public, underscoring the pressing need for targeted community initiatives, media campaigns, and educational interventions. These efforts are paramount for improving awareness, early detection, and timely response, especially in countries with lower levels of community stroke awareness.

Exploring Education Interventions for Stroke Prevention Among Adults and Older Individuals: A Scoping Review

Background and Aims

This investigation aims to conduct a comprehensive review of educational interventions targeting stroke prevention to provide effective preventive measures and optimize resource utilization in adults and the elderly populations.

Methods

A comprehensive literature search was conducted on PubMed, SCOPUS, and Embase for articles published online or in print until February 22, 2022. Inclusion criteria for studies were limited to the studies that examined stroke education or training interventions aimed at improving knowledge among adults aged 30 years and above, with a particular focus on older adults.

Results

A review of 97,848 papers was conducted, resulting in the inclusion of 19 papers. Of these, six were randomized controlled trials (RCTs), six were non-randomized studies, five were campaign studies, one was a cross-sectional study, one was a pilot study, and one was a prospective study. The provided information describes various interventions and educational programs related to stroke awareness, prevention, and management. The intervention subjects were categorized as awareness of warning signs and symptoms of stroke (n = 14), comprehensive awareness campaigns (n = 5), multilevel strategies for stroke education (n = 4), community-based nursing education and rehabilitation program (n = 5), multimedia campaign for 9-1-1 awareness (n = 3), and self-management interventions (n = 1).

Conclusion

The categorized interventions, addressing awareness of warning signs and symptoms, comprehensive awareness campaigns, multilevel strategies, community-based nursing education and rehabilitation programs, multimedia campaigns for 9-1-1 awareness, and self-management interventions, collectively enrich our understanding of the multifaceted approaches to stroke education.

Assessing the efficacy of an educational video on stroke knowledge in Lebanon: a single-arm interventional study

OBJECTIVE

This study aimed to assess the public's knowledge of stroke before and after viewing an educational video about stroke risk factors, preventive measures, and alarming signs.

METHODS

A single-arm interventional study was conducted in Lebanon using a 3-minute video-based education about stroke. A pre- and post-structured questionnaire compared the level of knowledge about stroke.

RESULTS

The study included 685 participants. Knowledge of stroke, risk factors, warning signs, treatment, and preventive measures significantly increased post-educational video sessions. A higher baseline knowledge score was associated with a family history of stroke (Beta = 1.76) and being a healthcare professional (Beta = 3.35). Participants between 25 and 34 years (Beta=-1.39) and those with a high risk of stroke (Beta=-1.03) were significantly associated with a lower knowledge score.

CONCLUSION

This study demonstrated the effectiveness of a video-based educational tool to raise awareness about stroke. Short, targeted audio-visual resources using lay language can convey health education messages and influence behavioral changes. The community can benefit from a large-scale educational campaign that targets different socio-economic statuses to enhance knowledge of stroke and save lives.

Complete Blood Count Parameters as Prognostic Factor of Stroke: A Systematic Review

Introduction

Stroke is known as a common cause of disability all over the world. Stroke prognosis estimation has always been a topic of interest. In this study, it was tried to investigate the prognostic value of laboratory findings of complete blood count in a systematic review.

Methods

In this systematic review, literature from Medline via (PubMed, Ovid) Embase, Scopus, Cochrane Library, and ProQuest between 1988 and 2020 were included. A combination of Mesh and free terms were included in the search strategy: "Stroke", "Red Cell Distribution Width", "Blood Cell Count", "Mean corpuscular hemoglobin", and "Mean Corpuscular Volume" and with the abbreviation, in all fields. Data synthesis was achieved using content analysis.

Results

Elevated red blood cell distribution width was associated with stroke, cardiovascular events, and all-cause deaths among patients with prior stroke. Mean platelet volume has not any prognostic significance in ischemic stroke. There was a poor association between mean corpuscular volume (MCV) and stroke prognosis. Globulin and hemoglobin level predicted short-term mortality following acute ischemic stroke.

Conclusion

Complete blood count as a routine and efficient test performed in health care centers can be used to estimate the prognosis of stroke.

Awareness, Recognition, and Response to Stroke among the General Public-An Observational Study

Objective  To evaluate awareness and response to stroke among the general public.

Materials and Methods  In this prospective, observational study, self-reported stroke awareness questionnaire was administered in 2000 consecutive participants who visited outpatient clinic of a tertiary care hospital. For data analysis, comparison included for awareness of stroke and response in case of stroke.

Results  The average age of the study participants was 39.64 ± 15.55 (17–85), with 651(32.6%) women. Among the respondents, 786(39.3%) participants mentioned stroke as blood clot in the brain; 268(13.4%) stated it as brain hemorrhage. Awareness of stroke was higher in people in cities (71.0 vs. 8.5%; p  < 0.001) and graduates (75.3 vs. 60.9%; p  < 0.001) or knew a family member or friend who had stroke (42.7 vs. 30.4%; p  < 0.001). Most commonly recognized risk factors included stress (1,152; 57.6%) and hypertension (1,148; 57.4%). Most identified warning sign was weakness of one side of body (807; 40.4%) and speech impairment (658; 32.9%). Participants who were aware of stroke knew a greater number of risk factors (3.75 ± 2.88 vs. 2.45 ± 2.66; p  < 0.001) and warning signs (2.85 ± 2.25 vs. 1.49 ± 1.41; p <0.001). Among 1,138 participants who were aware of stroke, 166 (14.6%) participants knew one correct response in case of a stroke, either call a doctor (49.3 vs. 35.0%; p <0.001) or call an ambulance (41.1 vs. 34.9%; p  = 0.055). Participants who knew one correct response to stroke had at least a family member/friend who had stroke (44.1 vs. 34.3%; p  < 0.022).

Conclusion  We report that among 56.9% of the participants who were aware of stroke most could not name more than four risk factors or three warning signs of stroke. Only 14.6% of those aware of stroke knew appropriate response to stroke.

Knowledge, Prevention Practice and Associated Factors of Stroke Among Hypertensive and Diabetic Patients - A Systematic Review

INTRODUCTION

Because of the inadequate level of public awareness of the disease, the incidence of stroke has been sharply rising. Eventually, due to the prehospital delay, many stroke cases could not be eligible for thrombolysis thereby poor rehabilitative outcome has been tremendously increased. Thus, this study aimed to review the level of knowledge, prevention practice, and associated factors of stroke among hypertensive and diabetic patients.

METHODS

A systematic review of primarily published articles (2010-2020) related to knowledge and prevention practices of stroke was performed by searching online electronic databases like PubMed, Google Scholar, Refseek, Science direct, ResearchGate, and manual Google search by using the keywords and MeSH terms. Studies conducted on knowledge and prevention practices amongst hypertensive and/or diabetic patients were included.

RESULTS

Out of 531 searched studies, 42 articles were identified to be reviewed. The reported overall knowledge of stroke was ranging from 4.4% to 79%. Knowledge to the signs/symptoms of stroke was 23.6% to 87%. However, 15% to 77% of subjects were also reported that they did not know any sign of stroke. The range of risk factor knowledge was 10.5% to 86.6%. The reported level of stroke prevention practice was 2.4% to 72% but physical activity and weight reduction practice were relatively low. Inadequate level of knowledge and prevention practice of stroke was related to elderly, female gender, uneducated, unmarried, rural residents, economically low, comorbidity and unemployed individuals.

CONCLUSION

The current finding revealed that the level of knowledge and prevention practice of stroke was inadequate. Hence, the finding highlights health educational programs should be planned as an important avenue to enhance stroke awareness among the high-risk populations.

Comparative Evaluation of Stroke Awareness of Individuals Whose First-Degree Relatives had a Stroke and that of Individuals Whose First-Degree Relatives Did Not

OBJECTIVE

To assess the stroke awareness levels of individuals whose first-degree relatives had a stroke and to compare the results with those of individuals whose first-degree relatives did not have a stroke.

MATERIALS AND METHODS

This cross-sectional study was conducted between March and May 2019, with first-degree relatives of patients who had a stroke (group 1) and a comparable set of individuals whose first-degree relatives did not have a stroke (group 2). Participants were asked to complete a questionnaire asking about signs and symptoms, risk factors, treatment options, information sources, responses after the development of stroke, and early treatment of stroke.

RESULTS

In response to the questions about the signs and symptoms of stroke, group 1 mentioned dizziness and comprehension disorder as a symptom of stroke more frequently than the other group. Stress was the second most frequently mentioned risk factor (by 81% of group 1 and 80.5% in group 2). When the participants were asked about the sources of information about stroke, family circle and friends were the most frequently mentioned sources for both groups.

CONCLUSION

The present study can serve as a guide in planning training to improve stroke awareness in the future, especially by including individuals whose first-degree relatives had a stroke.

Level of Knowledge on Stroke and Associated Factors: A Cross-Sectional Study at Primary Health Care Centers in Morocco

Background:

Stroke is increasingly becoming a major cause of disability and mortality. However, it can be prevented by raising awareness about risk factors and early health care management of patients.

Objective:

The aim of this study is to assess the level of knowledge on stroke, its risk factors, and warning signs in the population attending urban primary health care centers in the city of Agadir, Morocco.

Methods:

This is a multicentric cross-sectional study with a descriptive and analytical purpose. The study was conducted at five urban primary health care centers in Agadir in centralwest Morocco. All persons over the age of 18 years who consulted the health centers and who agreed to fill in the questionnaire were recruited, except for the foreign population and health workers. An interview questionnaire was used to assess the level of knowledge on stroke.

Findings:

A total of 469 participants were involved in the study. The median knowledge score was 8 (Interquartile range 4–13). High blood pressure (55.7%), depression and stress (48.8%) were the most well-known risk factors. Sudden weakness of the face, arms or legs (37.3%) was the main warning sign cited by the participants. Multivariate analysis revealed that illiteracy (OR 1.92; CI_95%: 1.08–3.44) primary education (OR 3.43; CI_95%: 1.63–7.21), rural residential (OR 1.67; CI_95%: 1.07–2.59), no history of stroke among respondents (OR 16.41; CI_95%: 4.37–61.59) and no history of stroke among relatives, acquaintances, or neighbors (OR 4.42; CI_95%: 2.81–6.96), were independently associated with a lower level of knowledge of stroke (Table 4).

Conclusions:

The low level of knowledge on stroke among this Moroccan population indicates the importance of implementing stroke education initiatives in the community. More specifically, proximity education and awareness programs ought to be considered to anchor lifestyle preventive behaviors along with appropriate and urgent actions regarding the warning signs of stroke.
