Background and Purpose: Clinicians will increasingly encounter adult patients who were born preterm and will need to understand their long-term sequelae. Adult survivors of preterm birth have been reported to have increased risks of hypertension and other stroke risk factors. However, their stroke risks have seldom been examined and the findings are discrepant, possibly due to small sample sizes, insufficient follow-up, or survivor bias. We examined whether preterm birth is associated with stroke in a large population-based cohort. Methods: A national cohort study was conducted of all 2 140 866 singletons born in Sweden from 1973 to 1994 who survived to age 18 years, who were followed up for first-time stroke through 2015 (maximum age 43 years). Cox regression was used to examine stroke risks associated with gestational age at birth, adjusting for other perinatal and parental factors. Cosibling analyses assessed for potential confounding by shared familial (genetic or environmental) factors. Results: In 28.0 million person-years of follow-up, 4861 (0.2%) people were diagnosed with stroke. At ages 18 to 43 years, the adjusted hazard ratio for stroke associated with preterm birth (<37 weeks) was 1.26 (95% CI, 1.12–1.43; P <0.001), and further stratified was 1.42 (1.11–1.81; P =0.005) for early preterm (22–33 weeks) and 1.22 (1.06–1.40; P =0.004) for late preterm (34–36 weeks), compared with full-term (39–41 weeks). Positive associations were found with both hemorrhagic stroke (early preterm: adjusted hazard ratio, 1.42 [95% CI, 1.04–1.94]; any preterm: 1.15 [0.97–1.35]) and ischemic stroke (early preterm: adjusted hazard ratio, 1.33 [95% CI, 0.87–2.03]; any preterm: 1.31 [1.07–1.60]). These findings were similar in men and women and only partially explained by shared determinants of preterm birth and stroke within families. Conclusions: In this large national cohort, preterm birth was associated with increased risks of both hemorrhagic and ischemic stroke in adulthood. Preterm birth survivors need early preventive evaluation and long-term clinical follow-up to reduce their lifetime risk of stroke.

Abstract Objectives To examine the long term mortality associated with preterm delivery in a large population based cohort of women, and to assess for potential confounding by shared familial factors. Design National cohort study. Setting Sweden. Participants All 2 189 477 women with a singleton delivery in 1973-2015. Main outcome measures All cause and cause specific mortality up to 2016, identified from nationwide death records. Cox regression was used to calculate hazard ratios while adjusting for confounders, and co-sibling analyses assessed the potential influence of unmeasured shared familial (genetic and environmental) factors. Results In 50.7 million person years of follow-up, 76 535 (3.5%) women died (median age at death was 57.6). In the 10 years after delivery, the adjusted hazard ratio for all cause mortality associated with preterm delivery (<37 weeks) was 1.73 (95% confidence interval 1.61 to 1.87), and when further stratified was 2.20 (1.63 to 2.96) for extremely preterm delivery (22-27 weeks), 2.28 (2.01 to 2.58) for very preterm delivery (28-33 weeks), 1.52 (1.39 to 1.67) for late preterm delivery (34-36 weeks), and 1.19 (1.12 to 1.27) for early term delivery (37-38 weeks) compared with full term delivery (39-41 weeks). These risks declined but remained significantly raised after longer follow-up times: for preterm versus full term births, 10-19 years after delivery, the adjusted hazard ratio was 1.45 (95% confidence interval 1.37 to 1.53); 20-44 years after delivery, the adjusted hazard ratio was 1.37 (1.33 to 1.41). These findings did not seem to be attributable to shared genetic or environmental factors within families. Several causes were identified, including cardiovascular and respiratory disorders, diabetes, and cancer. Conclusions In this large national cohort of women, the findings suggested that preterm and early term delivery were independent risk factors for premature mortality from several major causes. These associations declined over time but remained raised up to 40 years later.

Abstract Aims/hypothesis Preterm birth (gestational age <37 weeks) has been associated with insulin resistance early in life. However, no large population-based studies have examined risks of type 1 and type 2 diabetes and potential sex-specific differences from childhood into adulthood. Clinicians will increasingly encounter adults who were born prematurely and will need to understand their long-term risks. We hypothesised that preterm birth is associated with increased risks of type 1 and type 2 diabetes into adulthood. Methods A national cohort study was conducted of all 4,193,069 singletons born in Sweden during 1973–2014, who were followed up for type 1 and type 2 diabetes identified from nationwide diagnoses and pharmacy data to the end of 2015 (maximum age 43 years; median age at the end of follow-up 22.5 years). Cox regression was used to adjust for potential confounders, and co-sibling analyses assessed the influence of shared familial (genetic and/or environmental) factors. Results In 92.3 million person-years of follow-up, 27,512 (0.7%) and 5525 (0.1%) people were identified with type 1 and type 2 diabetes, respectively. Gestational age at birth was inversely associated with both type 1 and type 2 diabetes risk. Adjusted HRs for type 1 and type 2 diabetes at age <18 years associated with preterm birth were 1.21 (95% CI, 1.14, 1.28) and 1.26 (95% CI, 1.01, 1.58), respectively, and at age 18–43 years were 1.24 (95% CI, 1.13, 1.37) and 1.49 (95% CI, 1.31, 1.68), respectively, compared with full-term birth. The associations between preterm birth and type 2 (but not type 1) diabetes were stronger among females (e.g. at age 18–43 years, females: adjusted HR, 1.75; 95% CI, 1.47, 2.09; males: 1.28; 95% CI, 1.08, 1.53; p < 0.01 for additive and multiplicative interaction). These associations were only partially explained by shared genetic or environmental factors in families. Conclusions/interpretation In this large national cohort, preterm birth was associated with increased risk of type 1 and type 2 diabetes from childhood into early to mid-adulthood. Preterm-born children and adults may need early preventive evaluation and long-term monitoring for diabetes.

Statin Prescription

Background and Purpose: Statins are frequently initiated in patients aged 80 years and older after an ischemic stroke, even though evidence on prevention of recurrent cardiovascular disease is scarce. In this study, we seek evidence for statin prescription in the oldest old. Methods: We performed a retrospective cohort study in patients aged 65 years and older hospitalized for a first ischemic stroke between 1999 and 2016 without statin prescriptions in the year before hospitalization using the Clinical Practice Research Datalink. The age group 65 to 80 years was included to compare our results to current evidence on statin efficacy. The primary outcome was a composite of recurrent stroke, myocardial infarction, and cardiovascular mortality. The secondary outcome was all-cause mortality. A time-varying Cox model was used to account for statin prescription over time. We compared at least 2 years of statin prescription time with untreated and <2 years of prescription time. Analyses were adjusted for potential confounders. The number needed to treat was calculated based on the adjusted hazard ratios and corrected for deaths during the first 2 years of follow-up. Results: Five thousand nine hundred ten patients, aged 65 years and older were included, of whom 3157 were 80 years and older. Two years of statin prescription in patients aged 80 years and older resulted in both a lower risk of the composite end point (adjusted hazard ratio, 0.80 [95% CI, 0.62–1.02]) and all-cause mortality (adjusted hazard ratio, 0.67 [95% CI, 0.57–0.80]). After correction for the mortality of 23.9% of the patients during the first 2 years, the number needed to treat was 64 for the primary outcome during a median follow-up of 3.9 years and 19 for all-cause mortality. Conclusions: Statins initiated in patients aged 80 and older, discharged home after hospitalization for an ischemic stroke are associated with a reduction in cardiovascular events.

Background and Purpose: It is well-established that increasing treatment delay reduces the benefits of thrombolysis in patients with acute ischemic stroke. However, most studies focus on short-term outcomes. This study examined long-term outcomes according to time to thrombolysis in patients with first-time ischemic stroke. Methods: In this nationwide cohort study, all Danish patients with first-time ischemic stroke treated with intravenous thrombolysis between 2011 and 2017 and alive at discharge were identified through the Danish Stroke Registry. The association between time from symptom onset to thrombolysis and the long-term rate of the composite of death and recurrent ischemic stroke was examined using multivariable Cox regression and restricted cubic spline analysis. Results: The study population included 6252 patients with first-time ischemic stroke treated with thrombolysis (median age, 69 years [25th–75th percentile 60–78 years], 60% men). The median follow-up was 2.5 years (25th–75th percentile 1.2–4.1 years). The median time to thrombolysis was 138 minutes (25th–75th percentile 101–185 minutes), and the median National Institutes of Health Stroke Scale score at presentation was 5 (25th–75th percentile 3–10). The absolute 3-year risk of the composite outcome was 19.0% (95% CI, 16.4%–21.8%) in the 0 to 90 minute group, 23.3% (21.8%–24.9%) in the 91 to 180 minute group, and 23.8% (21.6%–26.1%) in the 181 to 270 minute group. Compared with thrombolysis within 90 minutes, time to thrombolysis >90 minutes was associated with a higher rate of the composite outcome (91–180 minute: adjusted hazard ratio, 1.25 [95% CI, 1.06–1.48]; 181–270 minutes: adjusted hazard ratio, 1.35 [95% CI, 1.12–1.61]). In restricted cubic spline analysis, the rate of the composite outcome increased with increasing time to thrombolysis and leveled off after 138 minutes. Conclusions: In this nationwide cohort of patients with ischemic stroke, the long-term rate of the composite of death and recurrent ischemic stroke increased with increasing time from symptom onset to initiation of thrombolysis.

Abstract Background In patients with acute myocardial infarction (AMI), history of atrial fibrillation (AF) and new onset AF during the early phase may be associated with a worse prognosis. Whether both conditions are associated with a similar risk of stroke and should be similarly managed is a matter of debate. Methods Based on the administrative hospital-discharge database, we collected information for all patients treated with AMI between 2010 and 2019 in France. The adverse outcomes were investigated during follow-up. Results Among 797,212 patients with STEMI or NSTEMI, 146,922 (18.4%) had history of AF, and 11,824 (1.5%) had new AF diagnosed between day 1 and day 30 after AMI. Patients with new AF were older and had more comorbidities than those with no AF but were younger and had less comorbidities than those with history of AF. Both groups with history of AF or new AF had less frequent STEMI and anterior MI, less frequent use of percutaneous coronary intervention but more frequent HF at the acute phase than patients with no AF. During follow-up (mean [SD] 1.8 [2.4] years, median [interquartile range] 0.7 [0.1–3.1] years), 163,845 deaths and 20,168 ischemic strokes were recorded. Using Cox multivariable analysis, compared to patients with no AF, history of AF was associated with a higher risk of death during follow-up (adjusted hazard ratio HR 1.06 95% CI 1.05–1.08) while this was not the case for patients with new AF (adjusted HR 0.98 95% CI 0.95–1.02). By contrast, both history of AF and new AF were associated with a higher risk of ischemic stroke during follow-up compared to patients with no AF: adjusted hazard ratio HR 1.29 95% CI 1.25–1.34 for history of AF, adjusted HR 1.72 95% CI 1.59–1.85 for new AF. New AF was associated with a higher risk of ischemic stroke than history of AF (adjusted HR 1.38 95% CI 1.27–1.49). Conclusion In a large and systematic nationwide analysis, AF first recorded in the first 30 days after AMI was associated with an increased risk of ischemic stroke. Specific management should be considered in order to improve outcomes in these patients after AMI. Funding Acknowledgement Type of funding source: None

Background Experimental and observational research suggests that combined epidural–general anesthesia may improve long-term survival after cancer surgery by reducing anesthetic and opioid consumption and by blunting surgery-related inflammation. This study therefore tested the primary hypothesis that combined epidural–general anesthesia improves long-term survival in elderly patients. Methods This article presents a long-term follow-up of patients enrolled in a previous trial conducted at five hospitals. Patients aged 60 to 90 yr and scheduled for major noncardiac thoracic and abdominal surgeries were randomly assigned to either combined epidural–general anesthesia with postoperative epidural analgesia or general anesthesia alone with postoperative intravenous analgesia. The primary outcome was overall postoperative survival. Secondary outcomes included cancer-specific, recurrence-free, and event-free survival. Results Among 1,802 patients who were enrolled and randomized in the underlying trial, 1,712 were included in the long-term analysis; 92% had surgery for cancer. The median follow-up duration was 66 months (interquartile range, 61 to 80). Among patients assigned to combined epidural–general anesthesia, 355 of 853 (42%) died compared with 326 of 859 (38%) deaths in patients assigned to general anesthesia alone: adjusted hazard ratio, 1.07; 95% CI, 0.92 to 1.24; P = 0.408. Cancer-specific survival was similar with combined epidural–general anesthesia (327 of 853 [38%]) and general anesthesia alone (292 of 859 [34%]): adjusted hazard ratio, 1.09; 95% CI, 0.93 to 1.28; P = 0.290. Recurrence-free survival was 401 of 853 [47%] for patients who had combined epidural–general anesthesia versus 389 of 859 [45%] with general anesthesia alone: adjusted hazard ratio, 0.97; 95% CI, 0.84 to 1.12; P = 0.692. Event-free survival was 466 of 853 [55%] in patients who had combined epidural–general anesthesia versus 450 of 859 [52%] for general anesthesia alone: adjusted hazard ratio, 0.99; 95% CI, 0.86 to 1.12; P = 0.815. Conclusions In elderly patients having major thoracic and abdominal surgery, combined epidural–general anesthesia with epidural analgesia did not improve overall or cancer-specific long-term mortality. Nor did epidural analgesia improve recurrence-free survival. Either approach can therefore reasonably be selected based on patient and clinician preference.

OBJECTIVEThe role of mechanical thrombectomy in pediatric acute ischemic stroke is uncertain, despite extensive evidence of benefit in adults. The existing literature consists of several recent small single-arm cohort studies, as well as multiple prior small case series and case reports. Published reports of pediatric cases have increased markedly since 2015, after the publication of the positive trials in adults. The recent AHA/ASA Scientific Statement on this issue was informed predominantly by pre-2015 case reports and identified several knowledge gaps, including how young a child may undergo thrombectomy. A repeat systematic review and meta-analysis is warranted to help guide therapeutic decisions and address gaps in knowledge.METHODSUsing PRISMA-IPD guidelines, the authors performed a systematic review of the literature from 1999 to April 2019 and individual patient data meta-analysis, with 2 independent reviewers. An additional series of 3 cases in adolescent males from one of the authors’ centers was also included. The primary outcomes were the rate of good long-term (mRS score 0–2 at final follow-up) and short-term (reduction in NIHSS score by ≥ 8 points or NIHSS score 0–1 at up to 24 hours post-thrombectomy) neurological outcomes following mechanical thrombectomy for acute ischemic stroke in patients < 18 years of age. The secondary outcome was the rate of successful angiographic recanalization (mTICI score 2b/3).RESULTSThe authors’ review yielded 113 cases of mechanical thrombectomy in 110 pediatric patients. Although complete follow-up data are not available for all patients, 87 of 96 (90.6%) had good long-term neurological outcomes (mRS score 0–2), 55 of 79 (69.6%) had good short-term neurological outcomes, and 86 of 98 (87.8%) had successful angiographic recanalization (mTICI score 2b/3). Death occurred in 2 patients and symptomatic intracranial hemorrhage in 1 patient. Sixteen published thrombectomy cases were identified in children < 5 years of age.CONCLUSIONSMechanical thrombectomy may be considered for acute ischemic stroke due to large vessel occlusion (ICA terminus, M1, basilar artery) in patients aged 1–18 years (Level C evidence; Class IIb recommendation). The existing evidence base is likely affected by selection and publication bias. A prospective multinational registry is recommended as the next investigative step.

Cystine Stones

Introduction: Cystine stone development is relatively uncommon among patients with urolithiasis, and most studies have reported only on small sample sizes and short follow-up periods. We evaluated clinical courses and treatment outcomes of patients with cystine stones with long-term follow-up at our center. Methods: We retrospectively analyzed 22 patients diagnosed with cystine stones between January 1989 and May 2019. Results: The median follow-up was 160 (range 6–340) months, and the median patient age at diagnosis was 46 (range 12–82) years. All patients underwent surgical interventions at the first visit (4 extracorporeal shockwave lithotripsy, 5 ureteroscopy, and 13 percutaneous nephrolithotripsy). The median number of stone events and surgical interventions per year was 0.45 (range 0–2.6) and 0.19 (range 0–1.3) after initial surgical intervention. The median time to stone events and surgical intervention was 2 years and 3.25 years, respectively. There was a significant difference in time to stone events and second surgical intervention when patients were divided at 50 years of age at diagnosis (p = 0.02, 0.04, respectively). Conclusions: Only age at a diagnosis under 50 was significantly associated with recurrent stone events and intervention. Adequate follow-up and treatment are needed to manage patients with cystine stones safely.

AbstractThe relationship between exercise and stroke recurrence is controversial. This study was designed to test whether an association exists between exercise and ischemic stroke recurrence in first-ever ischemic stroke survivors. Data were collected from January 2010 to June 2016. Baseline information was obtained during face-to-face interviews, and follow-up phone interviews were conducted every 3 months. Exercise type, frequency, intensity, and duration were recorded. Discrete-time survival analysis was used to determine the relationship between exercise and stroke recurrence. 760 first-ever ischemic stroke survivors who were able to exercise were enrolled. After adjusting for covariates, patients who exercised 3.5–7 h per week and more than 7 h per week had a lower relapse risk than patients who did not exercise (3.5–7: OR 0.415; > 7: OR 0.356). Moreover, if the fluctuation of exercise duration was over 4 h, the patients had a higher risk of stroke recurrence than those with variability of less than 2 h (OR 2.153, P = 0.013). Stroke survivors who engage in long-term regular mild exercise (more than 5 sessions per week and lasting on average 40 min per session) have a lower recurrence rate. Irregular exercise increases the risk of stroke recurrence.
