A questionnaire survey to assess lower urinary tract symptoms in patients with chronic stroke.

OBJECTIVES: In this study, we evaluated the prevalence of lower urinary tract symptoms and the associated clinical features in patients with chronic stroke. METHODS: Patients with stroke who had been regularly followed up at general medical hospitals in Okinawa, Japan were enrolled in the study. The patients were asked to complete a self-reported questionnaire regarding their physical activity, medical history, and the core lower urinary tract symptom score (CLSS) questionnaire, with anonymity. The association between each urinary disturbance category and the clinical characteristics of the patients such as age, gender, physical activity, and underlying disease was evaluated. RESULTS: In total, 51 patients (33 men and 18 women; mean age, 71.7 years) were eligible for analysis. The average time after the first stroke onset was 8.5 years. Nocturia and urgency incontinence had the greatest impact on the quality of life. Overactive bladder symptoms such as nocturia, urgency, urgency incontinence, and stress urinary incontinence were associated with age, female sex, and having a co-existing medical condition (such as ischemic heart disease, hypertension, and depression). Voiding symptoms such as slow stream and straining were associated with age and physical activity after stroke. CONCLUSIONS: Storage symptom is associated with not only neurological deficits but also sex and the presence of general diseases, whereas voiding symptom is influenced by physical activity in patients with chronic stroke. Therefore, lower urinary tract symptoms should be carefully monitored and physical rehabilitation should also be considered in patients with stroke.

Low muscle mass in patients with stroke on admission reduces walking ability at discharge.

BACKGROUND & AIMS: Reduced skeletal muscle mass may negatively influence postural retention and walking function. This study aimed to examine the influence of the skeletal muscle mass index on walking function in patients with stroke. METHODS: This study included patients with cerebral infarction aged ≥65 years. The Asian Working Group for Sarcopenia's skeletal muscle mass index criteria were used to classify the participants into the low and high skeletal muscle mass index groups. The patient characteristics of the two groups were compared. The primary and secondary outcome measures were independent walking and walking speed, respectively. RESULTS: In total, 174 participants were included. There were no significant differences in the length of hospital stay, rehabilitation volume, or functional independence measure score at discharge between the males and females. Multivariate logistic regression analysis revealed that independent walking was independently associated with the skeletal muscle mass index on admission. The SMI, as an explanatory variable, was independently associated with the comfortable and fastest walking speeds. Faster walking was associated with higher skeletal muscle mass indexes on admission for both males and females. CONCLUSIONS: A low skeletal muscle mass index negatively influences walking function improvement in patients with stroke. A strategy aimed at increasing skeletal muscle mass can have beneficial effects on walking function in patients with stroke.

Effects of blood pressure levels on case fatality after acute stroke.

OBJECTIVE: We evaluated the relationship between admission blood pressure (BP) and early prognosis in patients with acute stroke in a single cohort. DESIGN: The subjects comprised 1004 cases of brain infarction and 1097 cases of brain hemorrhage, who were admitted to hospitals on the day of stroke onset. Death within 30 days after onset was evaluated in relation to admission BP levels. RESULTS: In brain infarction, a U-shaped relationship was found between BP levels and mortality rate, with a nadir at systolic blood pressure (SBP) of 150-169 mmHg and at diastolic blood pressure (DBP) of 100-110 mmHg. After adjustments for age and sex, the highest relative risks (RR) was observed in the lowest BP levels compared with nadir groups, and were 2.69 [95% confidence interval (CI), 1.43-5.07] in SBP and 3.49 (95% CI, 1.58-7.74) in DBP. In subjects with previous hypertension, the relationship between prognosis and SBP level shifted significantly toward higher pressure by about 10 mmHg compared with those without previous hypertension. In subjects with brain hemorrhage, the relationship between BP levels and mortality rate showed a J-shape in SBP and a U-shape in DBP. Highest BP levels had the poorest prognoses (>/= 230 mmHg in SBP, RR = 4.13, 95% CI = 2.45-6.94; >/= 120 mmHg in DBP, RR = 1.83, 95% CI = 1.11-3.04). CONCLUSION: Lower and higher BP after brain infarction and higher BP after brain hemorrhage were predictors for poor early prognosis. In subjects with brain infarction, patients with previous hypertension had better outcomes at higher admission BP level than did normotensive patients.
