At 3 months, use of the Comprehensive Reminder System based on the Health Belief Model, yielded improvement in most health behaviors and blood pressure control in hypertensive ischemic stroke patients. Continued implementation of this intervention protocol is warranted to determine the long-term effect. Smoking and alcohol use behaviors need to be targeted with a different intervention.
The participants showed a relatively low level of stroke prevention knowledge and a moderate level of engagement in healthy behaviors. Pearson correlation coefficient between these 2 variables was 0.423 (P < .001). The results of multiple regression analysis showed that stroke prevention knowledge was positively influenced by education level; health behaviors were positively influenced by both gender and stroke prevention knowledge. Findings suggest that male hypertensive patients and those with a lower education level need targeted stroke education. Because knowledge was unrelated to behavior with respect to smoking, alcohol use, and low-salt diet, behavioral interventions should be explored to address these important risk factors among patients at risk for stroke.
The triglyceride-glucose (TyG) index is a reliable surrogate of insulin resistance and a marker for ischemic stroke (IS) incident. Whether the TyG index predicts stroke outcome remains uncertain. This study investigated the prognostic value of the TyG index in critically ill stroke patients. Methods: This was a retrospective observational study that included stroke patients, and all data were extracted from the eICU Collaborative Research Database. The TyG index was calculated as the ln [fasting glucose level (mg/dL) × triglyceride level (mg/dL)/2]. Outcomes included the hospital and intensive care unit (ICU) death. Multivariate logistic regression was used to determine independent risk factors. The smoothing curves and forest plots were illustrated. Results: A total of 4,570 eligible subjects were enrolled. The mean level of TyG index was 9.1 ± 0.7. The hospital and ICU mortality rate were 10.3 and 5.0%, respectively. TyG index as a continuous variable was associated hospital mortality in univariate analysis (OR 1.723, 95% CI 1.524-1.948, P < 0.001), adjusted model 1 (OR 1.861, 95% CI 1637-2.116, P < 0.001), and adjusted model 2 (OR 2.543, 95% CI 1.588-4.073, P < 0.001). TyG was also associated ICU mortality in univariate analysis (OR 2.146, 95% CI 1.826-2.523, P < 0.001), adjusted model 1 (OR 2.183, 95% CI 1.847-2.580, P < 0.001), and adjusted model 2 (OR 2.672, 95% CI 1.376-5.188, P < 0.001). The smoothing curves observed a continuous linear association after adjusting all covariates both in hospital and ICU mortality. Subgroup analysis demonstrated TyG index was associated with increased risk of hospital and ICU death in critically ill IS (P < 0.05), but not in hemorrhage stroke (P > 0.05). Conclusion: The TyG index is a potential predictor for hospital and ICU mortality in critically ill stroke patients, especially in IS patients.
Health behaviour a b s t r a c tPurpose: To investigate health behaviours and family function in stroke survivors, and evaluate the relationships among them.Methods: Patients who were diagnosed with stroke before and went back to neurology clinic between August 2011 and February 2012 in a tertiary hospital in Guangzhou, China were recruited for this study. Patients that were discharged and living at home for at least two months were asked to complete Family Assessment Device (FAD) and Health Promoting Lifestyle Profile, version II (HPLP-II) questionnaires. Individual items were scored between 1 and 4 points, and survey scores were compared and analysed using Pearson's correlations.
Results:The mean overall FAD family function score was 2.18 ± 0.25 points, with lower scores observed for problem solving and role function factors, and higher scores for communication, affection involvement, and behaviour control. The mean overall HPLP-II health behaviour score was 2.27 ± 0.36 points, with the highest score for the nutrition factor, and the lowest score for the exercise factor. The total score of family function negatively correlated with health behaviours (r ¼ À0.535, p < 0.01).Conclusions: Family function and health behaviours in stroke survivors are related, and need further improvement. Healthcare workers should pay close attention to patients' family function and health behaviours and find the reasons which may be influence their level.
Background: Risk factor management via behavioral change contributes substantially to secondary stroke prevention. The health belief model identified self-perceived risk as a significant factor in behavior change. In previous studies, people have tended to incorrectly estimate their risk of stroke. Little is known about the differences in stroke knowledge and health behaviors in patients who have had a stroke with different risks of stroke recurrence in China. Objective:The aims of this study were to determine the accuracy of self-perceived risk of stroke recurrence and to compare stroke knowledge and health behaviors in patients with hypertensive stroke at different recurrence risk strata. Methods: Baseline data from 174 patients in the Comprehensive Reminder System based on the Health Belief Model (CRS-HBM) study were used. Self-perceived risk was assessed via the susceptibility subcategory of the Short-Form Health Belief Model Scale, and actual risk was stratified using the Essen Stroke Risk Score. Results: Only 27.0% of the patients estimated their risks of stroke recurrence accurately. Patients who perceived themselves to be at higher risk had better knowledge of warning signs. Compared with patients who underestimated their risk of stroke recurrence, those who accurately estimated or overestimated their risk less likely to smoke. Conclusions: Most patients incorrectly estimated their risk of stroke recurrence. Communicating with patients about their future risk of recurrent stroke may help improve their stroke knowledge and health behaviors. Implementation of the Comprehensive Reminder System based on the Health Belief Model focusing on risk education aimed at prevention of stroke recurrence is warranted in China.
The intestinal microbiota shape the host immune system and influence the outcomes of various neurological disorders. Arteriosclerotic cerebral small vessel disease (aCSVD) is highly prevalent among the elderly with its pathological mechanisms yet is incompletely understood. The current study investigated the ecology of gut microbiota in patients with aCSVD, particularly its impact on the host immune system. We reported that the altered composition of gut microbiota was associated with undesirable disease outcomes and exacerbated inflammaging status. When exposed to the fecal bacterial extracts from a patient with aCSVD, human and mouse neutrophils were activated, and capacity of interleukin-17A (IL-17A) production was increased. Mechanistically, RORγt signaling in neutrophils was activated by aCSVD-associated gut bacterial extracts to up-regulate IL-17A production. Our findings revealed a previously unrecognized implication of the gut-immune-brain axis in aCSVD pathophysiology, with therapeutic implications.
BACKGROUND: Previous research has shown that men and women have different levels of stroke knowledge and differing health behaviors, which are important factors affecting blood pressure, as hypertension is a key risk factor for stroke occurrence. There has been little research on the effects of sex on the association between these 2 variables before the onset of stroke among Chinese hypertensive patients. METHODS: A cross-sectional study and a convenience sampling method were used. 272 male and 118 female hypertensive stroke patients were recruited. Each patient completed the Stroke Knowledge Questionnaire and the Health Behavior Scale for stroke patients. RESULTS: Compared with female patients, male patients had greater stroke knowledge and worse prestroke health behavior. The Pearson correlation coefficient between stroke knowledge and prestroke health behavior was 0.149 and 0.223 in male and female participants, respectively, P < .05. The results of a multiple regression analysis showed that Chinese hypertensive stroke patients' prestroke health behavior was significantly influenced by sex and stroke knowledge. CONCLUSION: Chinese male and female hypertensive stroke patients had disparities in stroke knowledge and prestroke health behavior; moreover, the correlation between these 2 variables before experiencing a hypertensive stroke was different between men and women. Men with hypertension should be considered at a higher risk for an initial or recurrent stroke. Developing sex-specific intervention for primary or secondary stroke prevention in China is essential.
