Stroke and stroke risk factors in women of reproductive age with a history of metabolic or bariatric surgery

ObjectiveTo determine the odds of stroke in women of reproductive age who have had metabolic or bariatric surgery (MBS).MethodsWe used the National Inpatient Sample (NIS), a publicly available dataset that samples 20% of hospital discharges. The study population includes women between the ages of 20 and 44 without a maternal admission code. Weighted logistic regression analyses were conducted to assess the odds of stroke in women with history of MBS compared to other women of reproductive age. Adjustment of odds was done for the following covariates: age, race, primary payer, severity of illness, depression, and obesity.ResultsWomen with a history of MBS had 52% lower adjusted odds of having a stroke than women who did not have MBS (OR = 0.48, 95%CI = 0.42-0.55). Additionally, women who had MBS had lower odds of risk factors for stroke, including diabetes (OR = 0.61, 95%CI = 0.59-0.63), hypertension (OR = 0.82, 95%CI = 0.81-0.84), hypercholesterolemia (OR=0.72, 95%CI =0.68-0.77), and migraine with aura (OR = 0.86, 95%CI = 0.74-0.99).ConclusionsAmong women of reproductive age with a history of MBS, there were lower odds of having a stroke and stroke risk factors when compared to women who did not have MBS. Additionally, this study showed a modest decrease in the odds of stroke among women with obesity when adjusted for other risk factors. Future research should focus on examining this finding further, with a focus on the moderation of the impact of having obesity on stroke risk independent of other stroke risk factors.     

Risk factors for stroke among urbanised Indonesian women of reproductive age: a hospital-based case-control study

BACKGROUND: Stroke is a major cause of death in South-East Asia, but few empirical data exist on its risks in Asian populations. METHODS: 235 cases and 682 age-matched controls of women of reproductive age (20-44 years) were recruited in 14 hospitals in Jakarta, Indonesia, between 1989 and 1993. Medical history was collected by a structured interview. In subsamples, glucosuria, serum cholesterol level and body mass index (BMI) were assessed. RESULTS: In these young and lean Muslim women, with few users of tobacco, alcohol or oral contraceptives, risk factors related to increased weight were strongly related to stroke occurrence. A history of hypertension or diabetes or increased serum cholesterol level showed odds ratios (ORs) of 13.9, 7.4 and 3.7, respectively. A BMI >27 (unadjusted for its potential consequences) caused an OR of 2.9. High social class and higher level of education (both OR 0.7) were associated with a lower risk of stroke, but levels of risk factors were higher in higher socio-economic classes. CONCLUSION: The expected transition in lifestyle, characterised by a higher intake of calories and less physical activity, will increase stroke risks in Indonesian women. Increasing wealth should go together with raising levels of health education on nutrition and physical activity.     

Medical management in patients following stroke and transitory ischemic attack: a comparison between men and women

STUDY OBJECTIVE: Differences between men and women in management and outcome following cerebrovascular events have been described. However, most of the differences observed have only been partially adjusted for baseline differences, or not at all. The objective of the present study was to compare acute and follow-up management between men and women after stroke and transitory ischemic attacks, adjusting for potential confounders. DESIGN: Patients with symptoms of stroke were included at admission to one of four participating hospitals in the inner city of Berlin, Germany. Risk factors, clinical characteristics, and acute management were assessed from medical records. Patients were asked about socioeconomic factors and follow-up management in a baseline interview and by postal questionnaire, respectively. The follow-up was 12 months. Multiple logistic regression analyses were used to assess odds ratios for management variables. RESULTS: A total of 558 patients were included (55% men, mean age 65+/-13 years; 45% women, 69+/-14 years). Indications for admission were stroke (74%) and transitory ischemic attacks (26%). In multivariable analyses, there were no differences in diagnostic procedures performed at baseline and in follow-up management between men and women. However, women were significantly more likely to receive hypoglycemic drugs (odds ratio 2.49; 95% confidence interval 1.33-4.63) in the acute management period. Regarding the need for nursing support/a nursing home after 12 months, there were no significant differences between men and women. CONCLUSIONS: After adjustment for differences in baseline characteristics, we only found few differences in acute and long-term management between men and women following hospital admission after suffering a cerebrovascular event.     

Valproic acid use in psychiatry: issues in treating women of reproductive age.

Valproic acid, a well known anticonvulsant, is being used by psychiatrists increasingly to manage bipolar and other affective disorders. Because of the demographics of the population affected by such psychiatric conditions, more women of childbearing age are likely to be exposed to this teratogenic drug. Neural tube defects (NTD) are the most common of the major anomalies associated with in utero valproic acid exposure, and are estimated to occur in 1% to 2% of exposed fetuses. Other teratogenic effects include facial dysmorphism, congenital cardiac defects, limb reduction defects and other skeletal anomalies. Prenatal diagnosis, in particular maternal serum alpha-fetoprotein screening and targeted ultrasonography, should be offered to all pregnant women exposed to valproic acid and couples need to be aware of the prenatal diagnostic options available to them. Periconceptual prophylaxis with high doses of folic acid is recommended for all women on valproic acid and counselling should also emphasize planning pregnancy to optimize folic acid supplementation. Psychiatrists should be aware of the teratogenic potential of valproic acid and know how to counsel their patients of reproductive age.     

Assessing the outcome of stroke: a comparison between MRI and clinical stroke scales

OBJECTIVES: To assess the correlation of diffusion-weighted (DWI) and perfusion-weighted imaging (PWI) findings with the severity of acute neurologic deficit and their ability to predict short and long-term clinical outcomes of stroke. The ability of DWI and PWI to predict the outcome was compared with the ability of clinical stroke scales to predict the outcome. METHODS: Forty-eight patients with acute stroke underwent diffusion DWI and PWI on the first and eighth day after the ictus. Clinical and functional scales were carried out before each scan and 3 months after the stroke. RESULTS: The volumes of both the DWI and the PWI lesions correlated well with the acute neurologic deficit and the final outcome. The first day PWI (r = 0.64) and the National Institutes of Health Stroke Scale (NIHSS) scores (r = 0.70) correlated well with the final outcome. However, in logistic regression analysis, only the NIHSS score at the acute stage was the only independent predictor of the long-term clinical outcome. CONCLUSION: While the PWI and DWI lesion volumes correlated well with the outcome of the stroke, the imaging measurements did not improve the prognostic power over plain clinical stroke scale scores.

Incidence and etiologies of stroke during pregnancy and puerperium as evidenced in Taiwanese women

BACKGROUND: Pregnancy is a known risk factor for stroke, but relatively few studies have been conducted in Asian populations to document the risk. This study aimed to analyze the incidence and etiologies of stroke occurring during pregnancy and puerperium in Taiwanese women. METHODS: From 1984 to 2002, female patients 15 through 40 years of age with first-ever stroke during pregnancy or within 6 weeks of delivery were recruited. Stroke was classified as ischemic stroke (IS), cerebral venous thrombosis (CVT), intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH). The incidence, time of stroke onset (1st through 3rd trimester or puerperium), and etiologies of different stroke subtypes were analyzed. RESULTS: Of 402 young female stroke patients, 49 had stroke during pregnancy and puerperium, including 16 with IS, 11 with CVT, 19 with ICH and 3 with SAH. After excluding referral patients, the incidences of pregnancy-related stroke were 46.2 (95% CI 30.7-69.5) per 100,000 pregnancies. 67% developed stroke in the 3rd trimester and puerperium, and 73% of CVT occurred in the puerperium period. Etiologies were well defined in 78% of patients. Eclampsia (37%) and arteriovenous malformation (26%) were the most important etiologies of ICH. For IS and CVT, rheumatic heart disease (44%) and coagulopathy (64%) were the major etiologies respectively. CONCLUSIONS: The incidence of stroke occurrence during pregnancy and puerperium in Taiwanese women is higher than that of Caucasian populations; the majority of strokes occurred in the 3rd trimester and puerperium, particularly CVT.
