Long-Term Mortality, Recovery, and Vocational Status After a Maternal Stroke: Register-Based Observational Case-Control Study.

BACKGROUND AND OBJECTIVES: Maternal stroke is a rare event with an increasing incidence. Data on the long-term prognosis after a maternal stroke are limited. We aimed to examine long-term mortality, recovery, vocational status and morbidity after a maternal stroke in a population-based setting including a comparison with matched, stroke-free controls. METHODS: In this register-based study with hospital chart validation, we included all women with a maternal stroke in Finland in 1987-2016 who survived the first year after the event. The recovery of the cases was assessed from the hospital charts by modified Rankin scale (mRS). Three controls matched by delivery year, age, and parity were selected for each case. All deaths until 2022 were identified from the Register for Causes of Death. Data on vocational status were obtained from Statistics Finland and morbidity from the Hospital Discharge Register and patient charts until year 2016. RESULTS: The study included 235 women with a maternal stroke and 694 matched controls. The median follow-up time was 17.5 years (interquartile range [IQR] 9.6-25.4) for mortality and 11.8 years (IQR 3.8-19.8) for vocational status and subsequent morbidity. Mortality among cases was 5.5% and among controls, 2.4% (age-adjusted odds ratio [OR] 2.3, 95% [CI] 1.1-4.9). At the end of the follow-up, 90.3% of the cases were independent in daily activities (mRS ≤2). In 2016, fewer women with a maternal stroke were working compared with controls (65.9% vs 79.1%, OR 0.5, 95% CI 0.4-0.7) and were more often receiving a pension (18.2% vs 4.9%, OR 4.4, 95% CI 2.7-7.3). Cerebrovascular events (age-adjusted OR 8.6 95% CI 4.4-17.1), cardiac diseases (age-adjusted OR 3.3, 95% CI 1.4-7.7), and major cardiovascular events were more common among cases during the follow-up (age-adjusted OR 7.6 95% CI 3.1-18.7). DISCUSSION: Despite having higher overall mortality and higher cardiovascular morbidity, the majority of the maternal stroke survivors recovered well. As expected, the vocational status of cases was inferior to that of controls, but most women were working at the end of the follow-up. Our study provides important information on the prognosis and sequalae after a maternal stroke to help in patient counseling and to improve secondary prevention.

Acute recanalization therapy for ischemic stroke during pregnancy and puerperium.

BACKGROUND: The safety and efficacy of intravenous thrombolysis (IVT) and endovascular thrombectomy for an ischemic stroke (IS) during pregnancy and puerperium are poorly studied. We evaluated the complications and outcome of recanalization therapy in maternal ISs. METHODS: A nationwide cohort of maternal ISs in Finland during 1987-2016 was collected by linking national healthcare registers: Medical Birth Register, Hospital Discharge Register, and Cause-Of-Death Register. The diagnoses were verified retrospectively from patient records. IVT-treated patients were compared to controls, who were young females with non-pregnancy-related IS from the Helsinki Stroke Thrombolysis Registry. RESULTS: Totally, 12 of 97 (12.4%) maternal ISs were treated with recanalization therapy. Compared to controls, IVT-treated maternal IS patients had more frequently early (age-adjusted odds ratio (aOR) = 7.63, 95% CI 1.49-39.04) and major (aOR = 8.59, 95% CI 2.09-35.31) neurological improvements, measured using the National Institute of Health Stroke Scale. Good functional outcomes (modified Rankin Scale 0-2) at three months were equally common in maternal ISs and controls. No other complications were observed in IVT-treated maternal ISs than 1 (9.1%) symptomatic nonfatal intracranial hemorrhage. Among maternal IS patients treated with recanalization or conventional therapy, good functional outcome at the end of the follow-up was less common in recanalization-treated patients (66.7% vs 89.4%, aOR = 0.22, 95% CI 0.052-0.90), but otherwise outcomes were similar. CONCLUSIONS: In this small nationwide cohort of maternal ISs, the complications of recanalization therapy were rare, and the outcomes were similar in IVT-treated maternal IS patients and controls. Maternal ISs should not be excluded from recanalization therapy in otherwise eligible situations.

Etiology of intracerebral hemorrhage during pregnancy or puerperium: A nationwide study.

BACKGROUND AND PURPOSE: Intracerebral hemorrhage during pregnancy or puerperium (pICH) is one of the leading causes of maternal death worldwide. However, limited epidemiological data exist on the etiology and outcomes of pICH, which is required to guide prevention and treatment. METHODS: A retrospective nationwide cohort study and a nested case-control study was performed in Finland 1987-2016. We identified women with incident pICH by linking the Medical Birth Register (MBR) and the Hospital Discharge Register (HDR). The clinical details were collected from patient records. Three matched controls with a pregnancy without ICH were selected for each case from the MBR. RESULTS: In total, 49 pICH cases were identified. Half of these cases occurred during pregnancy, and the other half during peripartum and puerperium. Based on the SMASH-U (structural vascular lesion, medication, amyloid angiopathy, systemic disease, hypertension, undetermined) classification, 35.4% of the patients had a systemic disease, most commonly preeclampsia, eclampsia, or HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome; 31.3% had a structural vascular lesion; 31.3% had an undetermined etiology; and one patient (2.1%) had hypertension. The most important risk factor was hypertensive disorders of pregnancy (HDP; odds ratio = 3.83, 95% confidence interval = 1.60-9.15), occurring in 31% of the cases. Maternal mortality was 12.5%, and 20.9% of the surviving women had significant disability (modified Rankin Scale = 3-5) 3 months after the pICH. Women with systemic disease had the worst outcomes. CONCLUSIONS: Even in a country with a comprehensive pregnancy surveillance system, the maternal mortality rate for pICH is high, and the sequelae are severe. Early recognition and treatment of the key risk factor, HDP, is crucial to help prevent this serious pregnancy complication.

Etiology and risk factors of ischemic stroke during pregnancy and puerperium: A population-based study.

INTRODUCTION: Ischemic stroke (IS) is an uncommon, but potentially life-changing, complication of pregnancy. The aim of this study was to analyze the etiology and risk factors of pregnancy-associated IS. PATIENTS AND METHODS: We collected a population-based retrospective cohort of patients diagnosed with IS during pregnancy or puerperium in Finland from 1987 to 2016. These women were identified by linking the Medical Birth Register (MBR) with the Hospital Discharge Register. Three matched controls were selected from MBR for each case. The diagnosis and temporal relationship of IS to pregnancy, and clinical details were verified from patient records. RESULTS: A total of 97 women (median age 30.7 years) were identified as having pregnancy-associated IS. The most common etiologies based on TOAST classification were cardioembolism in 13 (13.4%), other determined in 27 (27.8%) and undetermined in 55 (56.7%) patients. Fifteen patients (15.5%) had embolic strokes of undetermined sources. The most important risk factors were pre-eclampsia, eclampsia, gestational hypertension, and migraine. IS patients had more frequently traditional and pregnancy-related stroke risk factors than the controls (OR 2.38, 95% CI 1.48-3.84) and the risk of IS multiplied with the number of risk factors (4-5 risk factors: OR 14.21, 95% CI 1.12-180.48). DISCUSSION AND CONCLUSION: Rare causes and cardioembolism were frequent etiologies for pregnancy-associated IS, but in half of the women, the etiology remained undetermined. The risk of IS increased with the number of risk factors. Surveillance and counseling of pregnant women, especially with multiple risk factors, is crucial for the prevention of pregnancy-associated IS.

Pregnancy-associated stroke and the recurrence of stroke and other complications in subsequent pregnancies: Population-based retrospective cohort study.

OBJECTIVE: To examine the outcomes of the subsequent pregnancies from women with a previous pregnancy-associated stroke (PAS) in comparison to matched controls. DESIGN: Population-based retrospective cohort study. SETTING AND POPULATION: All women with a PAS in Finland 1987-2016 (n = 235) and controls (n = 694). METHODS: We identified all subsequent deliveries and induced and spontaneous abortions for women with a previous PAS and their matched controls from the Medical Birth Register and the Hospital Discharge Register until 2016. The number, course and outcomes of the subsequent pregnancies were compared. Patient records were studied for PAS recurrence. MAIN OUTCOME MEASURES: PAS recurrence and pregnancy complications. RESULTS: Women with a previous PAS had fewer subsequent deliveries: 73 (31.1%) women had 122 deliveries in all, whereas 303 (47.3%) of the controls had 442 deliveries (age-adjusted odds ratio [OR] 0.54, 95% CI 0.38-0.76). Hypertensive disorders of pregnancy (HDP) (17.2% versus 5.7%, age-adjusted OR 4.0, 95% CI 1.7-9.3), especially chronic hypertension (age-adjusted OR 5.9, 95% CI 1.5-24.7), and any diabetes during pregnancy (24.6% versus 14.5%, age-adjusted OR 2.0, 95% CI 1.1-3.8) were more common in cases. Regarding HDP, the difference between groups was explained by underlying factors such as index pregnancy HDP (multivariable OR 2.4, 95% CI 0.8-6.7). PAS recurred in four cases (5.5%). CONCLUSIONS: Subsequent pregnancies of women with a history of PAS are more often complicated with hypertensive disorders of pregnancy and any diabetes during pregnancy. PAS recurrence risk is considerable.

Inflammatory Breast Diseases during Lactation: Milk Stasis, Puerperal Mastitis, Abscesses of the Breast, and Malignant Tumors - Current and Evidence-Based Strategies for Diagnosis and Therapy.

BACKGROUND: Breast diseases during the lactation period are of high importance because they can be an essential cause for early cessation of breastfeeding. METHODS: To provide a comprehensive overview on the current recommendations of diagnostics and therapies, a systematic literature research was performed on a variety of online medical databases. RESULTS: The primary aim of all therapy is a quick reduction of pain to allow continued breastfeeding. Each particular form of breast disease requires a specific therapy. These can range from conservative measures to antibiotics and surgical procedures. All therapeutic measures, including pharmacotherapy, are normally not an indication for cessation of breastfeeding. CONCLUSION: Because the majority of breast diseases during the postnatal period occur only after the women have left the maternity clinics, all involved healthcare workers should educate women especially on preventive measures.

Reduced 11beta-hydroxysteroid dehydrogenase type 1 activity in obese boys.

OBJECTIVE: The incidence of childhood obesity and type 2 diabetes has reached epidemic proportions. Glucocorticoid excess causes central obesity and diabetes mellitus as seen in Cushing's syndrome. The 11beta-hydroxysteroid dehydrogenase type 1 enzyme (11beta-HSD1) regenerates active cortisol from inactive cortisone. Altered 11beta-HSD1 may cause tissue-specific Cushing's syndrome with central obesity and impaired glucose homeostasis. DESIGN, PATIENTS, AND METHODS: Clinical and laboratory characteristics, and anthropometric measurements were determined in 15 male and 6 female obese pubertal children (aged 12-18 years, Tanner stages 2-5). In addition, analyses of 24-h excretion rates of glucocorticoids were also performed in 21 age-, sex-, and pubertal stage-matched non-obese children using gas chromatographic-mass spectrometric (GC-MS) analysis. RESULTS: 11beta-HSD1 activity (urinary tetrahydrocortisol (THF) + 5alpha-THF/tetrahydrocortisone (THE) ratio) was lower in obese when compared with non-obese boys. In addition, obese children had a higher total cortisol metabolite excretion than non-obese children. 11beta-HSD1 activity was significantly related to age in lean and obese children. Standard deviation score (SDS)-body mass index did not correlate with 11beta-HSD1 activity, or with total cortisol metabolite excretion within each group. In obese children, 11beta-HSD1 activity and total cortisol metabolite excretion showed no correlation to waist-to-hip ratio, fat mass (percentage of body mass), or the homeostasis model assessment of insulin resistance index. CONCLUSIONS: In conclusion, our findings strongly suggest that 11beta-HSD1 activity increases with age, and is reduced in obese boys. In addition, obese children have a higher total cortisol metabolites excretion suggesting a stimulated hypothalamus-pituitary-adrenal axis.
