RESUMEN

BACKGROUND: Patients with acute intracerebral hemorrhage who are receiving factor Xa inhibitors have a risk of hematoma expansion. The effect of andexanet alfa, an agent that reverses the effects of factor Xa inhibitors, on hematoma volume expansion has not been well studied. METHODS: We randomly assigned, in a 1:1 ratio, patients who had taken factor Xa inhibitors within 15 hours before having an acute intracerebral hemorrhage to receive andexanet or usual care. The primary end point was hemostatic efficacy, defined by expansion of the hematoma volume by 35% or less at 12 hours after baseline, an increase in the score on the National Institutes of Health Stroke Scale of less than 7 points (scores range from 0 to 42, with higher scores indicating worse neurologic deficit) at 12 hours, and no receipt of rescue therapy between 3 hours and 12 hours. Safety end points were thrombotic events and death. RESULTS: A total of 263 patients were assigned to receive andexanet, and 267 to receive usual care. Efficacy was assessed in an interim analysis that included 452 patients, and safety was analyzed in all 530 enrolled patients. Atrial fibrillation was the most common indication for factor Xa inhibitors. Of the patients receiving usual care, 85.5% received prothrombin complex concentrate. Hemostatic efficacy was achieved in 150 of 224 patients (67.0%) receiving andexanet and in 121 of 228 (53.1%) receiving usual care (adjusted difference, 13.4 percentage points; 95% confidence interval [CI], 4.6 to 22.2; P = 0.003). The median reduction from baseline to the 1-to-2-hour nadir in anti-factor Xa activity was 94.5% with andexanet and 26.9% with usual care (P<0.001). Thrombotic events occurred in 27 of 263 patients (10.3%) receiving andexanet and in 15 of 267 (5.6%) receiving usual care (difference, 4.6 percentage points; 95% CI, 0.1 to 9.2; P = 0.048); ischemic stroke occurred in 17 patients (6.5%) and 4 patients (1.5%), respectively. There were no appreciable differences between the groups in the score on the modified Rankin scale or in death within 30 days. CONCLUSIONS: Among patients with intracerebral hemorrhage who were receiving factor Xa inhibitors, andexanet resulted in better control of hematoma expansion than usual care but was associated with thrombotic events, including ischemic stroke.

RESUMEN

BACKGROUND: Adult hypertension is a well-established risk factor for stroke in young adults (aged <55 years), and the effects are even more deleterious than at an older age. However, data are limited regarding the association between adolescent hypertension and the risk of stroke in young adulthood. METHODS: A nationwide, retrospective cohort study of adolescents (aged 16-19 years) who were medically evaluated before compulsory military service in Israel during 1985 to 2013. For each candidate for service, hypertension was designated after constructed screening, and the diagnosis was confirmed through a comprehensive workup process. The primary outcome was ischemic and hemorrhagic stroke incidence as registered at the national stroke registry. Cox proportional-hazards models were used. We conducted sensitivity analyses by excluding people with a diabetes diagnosis at adolescence or a new diabetes diagnosis during the follow-up period, analysis of adolescents with overweight, and adolescents with baseline unimpaired health status. RESULTS: The final sample included 1 900 384 adolescents (58% men; median age, 17.3 years). In total, 1474 (0.08%) incidences of stroke (1236 [84%] ischemic) were recorded, at a median age of 43 (interquartile range, 38-47) years. Of these, 18 (0.35%) occurred among the 5221 people with a history of adolescent hypertension. The latter population had a hazard ratio of 2.4 (95% CI, 1.5-3.9) for incident stroke after adjustment for body mass index and baseline sociodemographic factors. Further adjustment for diabetes status yielded a hazard ratio of 2.1 (1.3-3.5). We found similar results when the outcome was ischemic stroke with a hazard ratio of 2.0 (1.2-3.5). Sensitivity analyses for overall stroke, and ischemic stroke only, yielded consistent findings. CONCLUSIONS: Adolescent hypertension is associated with an increased risk of stroke, particularly ischemic stroke, in young adulthood.

RESUMEN

INTRODUCTION: The association disclosed between coronavirus disease 2019 (COVID-19) infection and ischemic stroke (IS) raises concern. The exact risk periods, which were not consistent between studies, require further investigation. METHODS: We linked two national databases: the COVID-19 database and the Israeli National Stroke Registry. The self-controlled case series method was used to estimate the association between COVID-19 infection and a first IS. The study population included all Israeli residents who had both a first IS event and a first COVID-19 diagnosis during 2020. The date of the PCR test served to define the day of exposure, and the 28 days following it were categorized into three risk periods: days 1-7, 8-14, and 15-28. A relative incidence (RI) with a 95% confidence interval (95% CI) was calculated based on the incidence rate of events in a post-exposure period, compared to the incidence rate in a control period. RESULTS: From January 1, 2020, to December 31, 2020, 308,015 Israelis aged 18+ were diagnosed with COVID-19 and 9,535 were diagnosed with a first IS. Linking the two databases, 555 persons had both diagnoses during 2020. The mean age of the study population was 71.5 ± 13.7, 55.1% were males, 77.8% had hypertension, 73.7% had hyperlipidemia, 51.9% had diabetes, and 28.5% had ischemic heart disease. Comparing the risk period and the control period, we found a very similar distribution of the cardiovascular risk factors. The risk for an acute IS was 3.3-fold higher in the first week following COVID-19 diagnosis, compared with a control period (RI = 3.3; 95% CI: 2.3-4.6). The RI among males (RI = 4.5; 95% CI: 2.9-6.8) was 2.2-fold higher compared to females. The increased risk did not last beyond the first week following exposure. CONCLUSION: Physicians should be aware of the elevated risk for IS among patients experiencing COVID-19, particularly among men with high burden of cardiovascular risk factors.

RESUMEN

Stroke is a leading cause of death and disability. In order to estimate the contribution of five modifiable risk factors to acute ischemic stroke (AIS) incidence in Israel, we conducted a case-control study based on first AIS cases aged 21-90 reported to the Israeli National Stroke Registry during 2014-2015, and controls from a national health survey conducted between 2013 and 2015. We calculated the population attributable risk (PAR) of each risk factor and the combined PAR for all risk factors (hypertension, diabetes, current smoking, obesity and hyperlipidemia), in all study population and by subgroups of young adults (age < 55) and older adults (age ≥ 55). The final analysis included 571, 577 and 500 matched pairs for all study population, young adults and older adults, respectively. Among young adults, current smoking and hypertension were the two most contributing risk factors for AIS, accounting for 33.6% (95% CI 27.3-39.9) and 28.9% (95% CI 22.1-35.7) of AIS cases, respectively. Among older adults, hypertension was the single most contributing risk factor for AIS and diabetes was the second most contributing risk factor for AIS, accounting for 64.9% (95% CI 57.3-72.5) and 25.7% (95% CI 17.5-33.9) of AIS cases, respectively. The combined PAR was significantly lower among young adults (PAR = 67.9%), compared with older adults (PAR = 80.7%). The combined PAR for all study population was 80.1% (95% CI 74.0-86.2), indicating that five common and modifiable risk factors explain ~80% of AIS incidence in Israel. Primary prevention strategies targeting these risk factors have the potential to drastically reduce stroke related morbidity and mortality.

RESUMEN

Backgrounds and aims: Evidence from recent years highlighted the importance of the Mediterranean diet for brain health. We investigated the association between adherence to Mediterranean diet and change in cognitive functions two decades later in patients with cardiovascular disease (CVD).Methods: Participants were men with a history of CVD, who previously participated in the Bezafibrate Infarction Prevention (BIP) trial between 1990 and 1997, had a food diary record, and underwent cognitive evaluations 14.6 ± 1.9 years (T1) and 19.9 ± 1.0 years after baseline (T2) as part of the BIP Neurocognitive study (n = 200, mean age at 57.3 ± 6.3 years). Adherence to the Mediterranean diet was determined from the self-administered 4-day food diary record, with patients categorized into high, middle and poor levels of adherence if they received >5, 4-5 and <4 points, respectively. Cognitive function was assessed using the NeuroTrax computerized battery. Linear mixed models were applied.Results: Among the 200 patients, 52 (26%) had poor adherence, 98 (49%) had middle adherence and 50 (25%) had high levels of adherence to the Mediterranean diet. Those categorized to the poor adherence level had poorer cognitive function at T1 compared to the other groups. Additionally, poor vs. high level of adherence was associated with a greater decline in overall cognitive performance [z-score = -0.23 and 95% confidence interval (CI), -0.43;-0.04; p = 0.021] and in visual spatial functions (-0.46 95% CI, -0.86;-0.06; p = 0.023).Conclusion: This study stresses the possible role of the Mediterranean diet in men with a high vascular burden and may set the ground for future intervention to reduce their risk for cognitive decline.

RESUMEN

Background and Purpose: There is a continuous rise in the prevalence of adolescent obesity and incidence of stroke among young adults in many Western countries, but the association between them is unclear. Methods: A nationwide population-based study of 1 900 384 Israeli adolescents (58% men; mean age, 17.3 years) who were evaluated before mandatory military service during 1985 and 2013. Body mass index was classified according to the US Center for Disease Control and Prevention percentiles. Primary outcome was a first stroke event as recorded by the Israeli National Stroke Registry between 2014 and 2018. Cox proportional hazard models were applied. Results: There were 1088 first stroke events (921 ischemic and 167 hemorrhagic; mean diagnosis age, 41.0 years). Adolescent body mass index was significantly associated with a graded increase in the risk for any stroke, ischemic stroke, but less so with hemorrhagic stroke. The hazard ratios for the first ischemic stroke event were 1.4 (95% CI, 1.2­1.6), 2.0 (95% CI, 1.6­2.4), and 3.4 (95% CI, 2.7­4.3) for the 50th to 84th percentile, overweight and obese groups, respectively, after adjustment for sex, age, and sociodemographic confounders with the 5th to 49th body mass index percentile group as the reference. The respective hazard ratios after further adjustment for diabetes status were 1.3 (1.1­1.5), 1.6 (1.3­2.0), and 2.4 (1.9­3.1). Results persisted when the cohort was divided by diabetes status and when ischemic stroke before age 30 was the outcome. Conclusions: High adolescent body mass index was associated with ischemic stroke in young adults with or without diabetes. The rising prevalence of adolescent obesity may increase the future burden of stroke in young adults.

RESUMEN

INTRODUCTION: The COVID-19 pandemic overwhelmed health-care systems worldwide, and medical care for other acute diseases was negatively impacted. We aimed to investigate the effect of the COVID-19 outbreak on admission rates and in-hospital care for acute stroke and transient ischemic attack (TIA) in Israel, shortly after the start of the pandemic. METHODS: We conducted a retrospective observational study, based on data reported to the Israeli National Stroke Registry from 7 tertiary hospitals. All hospital admissions for acute stroke or TIA that occurred between January 1 and April 30, 2020 were included. Data were stratified into 2 periods according to the timing of COVID-19 restrictions as follows: (1) "pre-pandemic" - January 1 to March 7, 2020 and (2) "pandemic" - March 8 to April 30, 2020. We compared the weekly counts of hospitalizations between the 2 periods. We further investigated changes in demographic characteristics and in some key parameters of stroke care, including the percentage of reperfusion therapies performed, time from hospital arrival to brain imaging and to thrombolysis, length of hospital stay, and in-hospital mortality. RESULTS: 2,260 cases were included: 1,469 in the pre-COVID-19 period and 791 in the COVID-19 period. Hospital admissions significantly declined between the 2 periods, by 48% for TIA (rate ratio [RR] = 0.52; 95% CI 0.43-0.64) and by 29% for stroke (RR = 0.71; 95% CI 0.64-0.78). No significant changes were detected in demographic characteristics and in most parameters of stroke management. While the percentage of reperfusion therapies performed remained unchanged, the absolute number of patients treated with reperfusion therapies seemed to decrease. Higher in-hospital mortality was observed only for hemorrhagic stroke. CONCLUSION: The marked decrease in admissions for acute stroke and TIA, occurring at a time of a relatively low burden of COVID-19, is of great concern. Public awareness campaigns are needed as patients reluctant to seek urgent stroke care are deprived of lifesaving procedures and secondary prevention treatments.

RESUMEN

PURPOSE: Recent research in epilepsy patients confirms our understanding of epilepsy as a network disorder with widespread cortical compromise. Here, we aimed to investigate the neocortical laminar architecture in patients with focal cortical dysplasia (FCD) and periventricular nodular heterotopia (PNH) using clinically feasible 3 T MRI. METHODS: Eighteen epilepsy patients (FCD and PNH groups; n = 9 each) and age-matched healthy controls (n = 9) underwent T1 relaxation 3 T MRI, from which component probability T1 maps were utilized to extract sub-voxel composition of 6 T1 cortical layers. Seventy-eight cortical areas of the automated anatomical labeling atlas were divided into 1000 equal-volume sub-areas for better detection of cortical abnormalities, and logistic regressions were performed to compare FCD/PNH patients with healthy controls with the T1 layers composing each sub-area as regressors. Statistical significance (p < 0.05) was determined by a likelihood-ratio test with correction for false discovery rate using Benjamini-Hochberg method. RESULTS: Widespread cortical abnormalities were observed in the patient groups. Out of 1000 sub-areas, 291 and 256 bilateral hemispheric cortical sub-areas were found to predict FCD and PNH, respectively. For each of these sub-areas, we were able to identify the T1 layer, which contributed the most to the prediction. CONCLUSION: Our results reveal widespread cortical abnormalities in epilepsy patients with FCD and PNH, which may have a role in epileptogenesis, and likely related to recent studies showing widespread structural (e.g., cortical thinning) and diffusion abnormalities in various human epilepsy populations. Our study provides quantitative information of cortical laminar architecture in epilepsy patients that can be further targeted for study in functional and neuropathological studies.

RESUMEN

OBJECTIVES: The Distal Motor Function (DMF) sub-score of the NIH Stroke Scale (NIHSS) was measured in the NINDS rt-PA Stroke Trials but is currently not included in the NIHSS. The correlation of DMF with the NIHSS Motor Arm Function (MAF) sub-score, the effect of IV tPA treatment on DMF, and whether adding DMF changes the utility of the NIHSS have not been analyzed. MATERIALS AND METHODS: MAF and DMF sub-scores were retrieved from the original NINDS rt-PA Stroke Trials for both sides of the body at baseline, 2 hours, 24 hours, 7-10 days, and 3 months after IV tPA treatment. MAF and DMF scores were correlated using Spearman correlation. Clustering of DMF and MAF scores was determined using a Bentler Comparative Fit Index (CFI) to estimate variation in NIHSS when adding DMF. The effect of IV tPA on DMF and MAF was assessed using a linear model comparing changes in scores from baseline to 3 months. RESULTS: MAF and DMF were highly correlated (p < 0.0001) across all time points for both dichotomous and continuous data on both sides. Intravenous tPA accounted for 21% of the change in DMF (p < 0.014, R2 = 0.0157, N = 423) and 39% of the change in MAF (p < 0.093, R2 = 0.0125, N = 547) from 0 to 3 months. On adding DMF to NIHSS, CFI decreased from 0.98 to 0.80 and DMF clustered with MAF, indicating that addition of DMF is unlikely to produce any discrepancy to NIHSS. CONCLUSIONS: Including DMF to the NIHSS does not appear to be of additional value. After IV tPA treatment, proximal and distal motor function in upper extremity strongly correlate over time but greater improvement in MAF is noted. Further research is needed on the role of IV tPA on minor strokes with deficits of DMF.

RESUMEN

INTRODUCTION: Despite the impressive decline in mortality from atherosclerotic cardiovascular diseases (ASCVD), these diseases still account for a large proportion of the overall morbidity and mortality worldwide. A vast amount of research has demonstrated the key role played by circulating lipoproteins, and especially low-density lipoprotein (LDL), in the etiology of atherosclerosis, and numerous studies have proven the efficacy of interventions that lower the atherogenic lipoproteins in reducing morbidity and mortality from ASCVD. While previous guidelines placed an emphasis on the use HMG-CoA reductase inhibitors (statins) for the treatment of dyslipidemia, recent studies have shown that other LDL cholesterol lowering drugs, including ezetimibe and the PCSK9 inhibitors, can provide additional benefit when used in combination with (and in certain cases instead of) statins. These studies have also shown that blood LDL cholesterol levels lower than previously recommended targets provide additional benefit, without evidence of a threshold beyond which the benefit ceases and without excess adverse effects. The updated guidelines were formulated by a committee that consisted of representatives from the Israeli Society for the Research, Prevention and Treatment of Atherosclerosis, the Israel Society of Internal Medicine, the Israeli Heart Association, the Israeli Neurology Association and the Israel Association of Family Medicine. They provide recommendations for revised risk stratification of patients, novel target goals, and the use of evidence-based treatment and follow-up strategies with reference to specific patient sub-groups.

RESUMEN

BACKGROUND: High body mass index (BMI) is a risk factor for type 2 diabetes and cardiovascular disease. However, its relationships with indices of carotid stiffness and plaque volume are unclear. We investigated associations of long-term measurements of BMI with indices of carotid stiffness and atherosclerosis among non-demented diabetes patients from the Israel Diabetes and Cognitive Decline (IDCD) study. METHODS: Carotid ultrasound indices [carotid intima media thickness (cIMT), distensibility, elastography and plaque volume] were assessed in N = 471 participants. Mean BMI across all MHS diabetes registry measurements and trajectories of BMI were calculated. BMI was categorized into three trajectory groups representing: a relatively stable normal weight (n = 185, 44%), overweight trajectory (n = 188, 44.8%) and a trajectory of obesity (n = 47, 11.2%). Linear and logistic regressions estimated associations of carotid indices with mean BMI and BMI trajectories. RESULTS: Compared to the normal weight trajectory, an obesity trajectory was associated with carotid distensibility (ß = - 3.078, p = 0.037), cIMT (ß = 0.095, p = 0.004), and carotid elastography (ß = 0.181, p = 0.004) but not with plaque volume (ß = 0.066, p = 0.858). Compared with the normal weight trajectory, an obesity trajectory was associated with increased odds for impaired carotid distensibility (OR = 2.790, p = 0.033), impaired cIMT (OR = 5.277, p = 0.001) and large carotid plaque volume (OR = 8.456, p = 0.013) but not with carotid elastography (OR = 1.956, p = 0.140). Mean BMI was linearly associated with Distensibility (ß = - 0.275, p = 0.005) and cIMT (ß = 0.005, p = 0.026). CONCLUSIONS: Long-term measurements of adiposity are associated with indices of carotid stiffness and plaque volume among older type 2 diabetes adults.

RESUMEN

BACKGROUND: Autonomic imbalance is linked with multiple health conditions, yet its associations with frailty were rarely studied. We assessed the relationship of resting heart rate (RHR) and visit-to-visit heart rate variability (HRV) with future frailty among elderly men with coronary heart disease (CHD). METHODS: Three-hundred-six community-dwelling men with CHD who participated in the Bezafibrate Infarction Prevention (BIP) trial (1990-1998; mean age 56.6 ± 6.5 years) underwent assessment of physical frailty in 2011-2013 (mean age 77.0 ± 6.4 years). Mean RHR and visit-to-visit HRV were calculated from electrocardiogram as indicators of autonomic imbalance. Nominal logistic and linear regression models were used to assess the relationships of RHR and HRV with frailty status and its components (i.e. gait speed, grip strength, weight loss, exhaustion and activity), respectively. Adjustments were made for various demographic, clinical and metabolic covariates. RESULTS: Of the 306 men, 81 (26%) were frail and 117 (38%) were prefrail. After controlling for potential confounders, RHR, but not visit-to-visit HRV, was associated with higher odds of being prefrail [OR = 1.44 (95%CI 1.15, 1.79)] and frail [OR = 1.35 (95%CI 1.03, 1.77)]. Each 5-bpm increase in RHR was associated with weaker grip (ß= -1.12 ± 0.32 kg; p-value < .001) and slower gait speed (ß = 0.19 ± 0.08s/m; p-value = .022). CONCLUSIONS: Midlife RHR may be associated with late-life frailty in men with CHD.

RESUMEN

OBJECTIVE: We investigated the association between severity of angina pectoris (AP) and subsequent late-life frailty among men with cardiovascular disease (CVD). METHOD: A subset of 351 men (mean age at baseline 56.7 ± 6.5 years) who previously participated in the Bezafibrate Infarction Prevention, BIP trial (1990-1997) underwent a neurovascular evaluation as part of the BIP Neurocognitive study 15.0 ± 3.0 years after baseline (T1) and a frailty evaluation according to Fried 19.9 ± 1.0 years after baseline (T2). Severity of AP was assessed at baseline of the BIP trial using the Canadian Cardiovascular Society angina classification. We assessed the odds of being in the advanced rank of frailty status (robust, pre-frail, and frail) using ordered logistic regression. RESULTS: Among 351 participants, 134 (38.2%) were classified as pre-frail and 100 (28.5%) as frail. Frailty was found among 42% participants in the AP class ≥2 and among 26% participants in the AP class <2. Adjusting for demographic, health-related and cognitive variables, odds ratio (OR), and 95% confidence interval (95% CI) for advanced rank of frailty was 2.68 (95% CI: 1.29-5.59) comparing AP class ≥2 to AP class <2. DISCUSSION: Among men with CVD, severity of AP should be taken into risk consideration due to its strong association with late-life frailty, particularly among inactive participants and participants with cerebral microvascular damage.

OBJECTIVE: To examine whether high ambient temperature and diurnal temperature range during the summer are associated with risk of stroke/transient ischemic attack (TIA). METHODS: A time-stratified case-crossover study design was conducted. The study sample comprised all individuals aged ≥50 years who had a stroke/TIA reported to the Israeli National Stroke Registry between 2014 and 2016 during the summer season. Daily temperature data were retrieved from the Israel Meteorological Service. Conditional logistic regression models were used with relative humidity and air pollution as covariates. RESULTS: The sample included 15,123 individuals who had a stroke/TIA during the summer season (mean age 73 ± 12 years; 54% males). High ambient temperature was associated with stroke/TIA risk starting from the day before the stroke event, and increasing in strength over a six-day lag (OR = 1.10 95%CI 1.09-1.12). Moreover, a larger diurnal temperature range prior to stroke/TIA occurrence was associated with decreased stroke/TIA risk (OR = 0.96 95%CI 0.95-0.97 for a six-day lag). CONCLUSIONS: High ambient temperature may be linked to increased risk of cerebrovascular events in subsequent days. However, relief from the heat during the night may attenuate this risk.

RESUMEN

INTRODUCTION: Little is known about the association between obesity and sarcopenia - age-related loss of muscle mass and function - among patients with cardiovascular disease. We investigated the association between overweight, obesity, and sarcopenia among community-dwelling men in Israel with cardiovascular disease. METHODS: A subset of 337 men (mean age at baseline 56.7 [SD, 6.5]) who previously (1990-1997) participated in the Bezafibrate Infarction Prevention trial underwent a neurovascular evaluation as part of the Bezafibrate Infarction Prevention Neurocognitive Study 15.0 (SD, 3.0) years after baseline and a sarcopenia evaluation 19.9 (SD, 1.0) years after baseline. We applied a multinomial logistic model to estimate odds ratios and 95% CIs for 3 categories of sarcopenia: no evidence of sarcopenia (ie, robust), probable sarcopenia, and sarcopenia. RESULTS: We found sarcopenia among 54.3% of participants with obesity (body mass index [BMI, in kg/m2] ≥30.0), 37.0% of participants who were overweight (25.0 ≤ BMI ≤29.9), and 24.8% of participants with normal weight (BMI 18.5 to 24.9). In a comparison of BMI ≥25.0 and BMI <25.0, adjusting for covariates, the odds ratio of having probable sarcopenia was 3.27 (95% CI, 1.68-6.36) and having sarcopenia was 5.31 (95% CI, 2.50-11.27). CONCLUSION: We found a positive association between obesity and late-life sarcopenia and suggest that obesity might be an important modifiable risk factor related to sarcopenia among men with cardiovascular disease.

RESUMEN

Aim: We investigated the relationship between midlife C-reactive protein (CRP) levels in men with coronary heart disease (CHD) and depressive symptoms at old age. CRP levels were measured in a subset of patients with CHD, who previously participated in a secondary prevention trial.Methods: Depressive symptoms were evaluated in survivors of the original cohort 15.0 ± 3 and 19.9 ± 1 years later (T1, n = 463 and T2, n = 314 respectively) using the Geriatric Depression Scale (GDS), 15-item version. Logistic regression was used to estimate ORs and 95%CIs for presence of potentially clinically significant depressive symptoms (GDS ≥5) at T1 and T2.Results: Adjusting for demographic and health-related variables, the OR (95%CI) for GDS ≥5 was 1.23 (0.65-2.33); p = .53 at T1 and 2.36 (1.16-4.83); p = .018 at T2 in the top CRP tertile compared to the others. Similarly, consistently high CRP levels in the top tertile at baseline and 2 years later, were associated with OR of 2.85 (95%CI 1.29-6.30); p = .01 for GDS ≥5 at T2.Conclusions: Presence and persistence of low-grade inflammation in men with CHD during midlife are associated with increased risk of depressive symptoms twenty years later. Among middle aged men with CHD, low-grade inflammation may provide an important added value for prediction of depression in old age.

RESUMEN

BACKGROUND: Patients with ischemic stroke or transient ischemic attack (TIA) are at increased risk for future cardiovascular events despite current preventive therapies. The identification of insulin resistance as a risk factor for stroke and myocardial infarction raised the possibility that pioglitazone, which improves insulin sensitivity, might benefit patients with cerebrovascular disease. METHODS: In this multicenter, double-blind trial, we randomly assigned 3876 patients who had had a recent ischemic stroke or TIA to receive either pioglitazone (target dose, 45 mg daily) or placebo. Eligible patients did not have diabetes but were found to have insulin resistance on the basis of a score of more than 3.0 on the homeostasis model assessment of insulin resistance (HOMA-IR) index. The primary outcome was fatal or nonfatal stroke or myocardial infarction. RESULTS: By 4.8 years, a primary outcome had occurred in 175 of 1939 patients (9.0%) in the pioglitazone group and in 228 of 1937 (11.8%) in the placebo group (hazard ratio in the pioglitazone group, 0.76; 95% confidence interval [CI], 0.62 to 0.93; P=0.007). Diabetes developed in 73 patients (3.8%) and 149 patients (7.7%), respectively (hazard ratio, 0.48; 95% CI, 0.33 to 0.69; P<0.001). There was no significant between-group difference in all-cause mortality (hazard ratio, 0.93; 95% CI, 0.73 to 1.17; P=0.52). Pioglitazone was associated with a greater frequency of weight gain exceeding 4.5 kg than was placebo (52.2% vs. 33.7%, P<0.001), edema (35.6% vs. 24.9%, P<0.001), and bone fracture requiring surgery or hospitalization (5.1% vs. 3.2%, P=0.003). CONCLUSIONS: In this trial involving patients without diabetes who had insulin resistance along with a recent history of ischemic stroke or TIA, the risk of stroke or myocardial infarction was lower among patients who received pioglitazone than among those who received placebo. Pioglitazone was also associated with a lower risk of diabetes but with higher risks of weight gain, edema, and fracture.

RESUMEN

BACKGROUND: Stroke is a leading cause of mortality, disability and functional impairment. We present clinical and patient-reported outcomes 3-months after stroke in patients from the National Acute Stroke Israeli registry (NASIS) 2016. METHODS: The NASIS registry includes all patients with acute cerebrovascular events admitted during 2-month periods every 3-years, at all hospitals and departments admitting acute stroke patients in Israel. The current work presents findings on 710 survivors after ischemic stroke or intracerebral hemorrhage (ICH) in NASIS 2016. Outcomes at 3-months were assessed using the modified Rankin Scale (mRS), questions about dysfunction and patient-reported outcomes assessed with the PROMIS 10 scale. RESULTS: Seven-hundred and ten patients were included, 696 (94.2%) with ischemic stroke and 41 (5.8%) with ICH. Mean age of participants was 70.2 years, 58% men. At 3-months, mRS scores were 0-1 for 43% of the patients, 2-3 for 29% and 4-5 for 28%. Functional impairment was more severe in patients with ICH than in ischemic stroke patients. Patients who were discharged from the hospital with functional impairment (mRS≥2) exhibited lower PROMIS 10 scores at 3-months compared to patients with no functional impairment at discharge. This finding was statistically significant in all the PROMIS 10 items, except for fatigue (p=0.874) and pain level (p=0.188). CONCLUSIONS: More than half of the patients needed help with their daily functioning 3-months after stroke. Most stroke survivors with functional impairment at discharge reported poor patient-reported outcomes. Post-stroke rehabilitation programs should aim at improving outcomes that are valuable to patients.

RESUMEN

BACKGROUND: Stroke is a leading cause of death and disability worldwide. Due to the high burden caused by stroke, the Israeli Ministry of Health initiated a national program for the treatment and prevention of stroke, including the establishment of an Israeli National Stroke Registry (INSR). In this article we will demonstrate the use of the INSR as a tool for monitoring the treatment of acute cerebrovascular events (stroke or transient ischemic attack). OBJECTIVES: 1. Assessing incidence rates of acute cerebrovascular events in Israel for the total population and by gender and ethnic group separately. 2. Presenting trends in a number of key indicators related to acute stroke care. METHODS: The INSR is based on data retrieval from hospital electronic medical records of all adult cases discharged with acute cerebrovascular diagnosis from January 1, 2014 on. Included in the current analysis were all cases reported to the INSR until June 31, 2017. RESULTS: The average annual incidence rate of cerebrovascular events in Israel was 3.2 cases per 1,000 people. Age-adjusted rates were significantly higher among Arabs, compared with the Jewish population. From 2014 to 2017 there was a moderate increase in the percentage of arrival by ambulance: from 43.2% to 49.0% and a significant increase in the percentage of head and neck vascular imaging performed: from 50.0% to 72.5%. Between 2014 and 2016 there was a significant increase in the percentage of t-PA administration, and in 2016-2017 the rates stabilized at 9.2%. The proportion of patients hospitalized in neurological wards was 38.0% - a slight increase from 35.0% in 2014. CONCLUSIONS: The INSR is an effective tool for monitoring morbidity and acute stroke care in Israel. Actions should be taken in order to raise public awareness of stroke warning signs and the establishment of stroke units with skilled multidisciplinary teams should become a priority. DISCUSSION: Compared with other western countries, rates of t-PA administration and arrival by ambulance in Israel are slightly low, rates of hospitalization in the neurological ward are significantly lower, and the lack of stroke units is most prominent.

RESUMEN

BACKGROUND AND PURPOSE: Stroke is a leading cause of morbidity and disability. We assessed trends in rates of hospitalized stroke and stroke severity on admission in a prospective national registry of stroke from 2004 to 2013. METHODS: All 6693 acute ischemic strokes and intracerebral hemorrhage in the National Acute Stroke Israeli participants ≥20 years old were included. Data were prospectively collected in 2004 (February-March), 2007 (March-April), 2010 (April-May), and 2013 (March-April). Rates of hospitalized stroke from 2004 to 2013 were studied using generalized linear models assuming a quasi-Poisson error distribution with a log link. Stroke severity on admission was determined using the National Institutes of Health Stroke Scale score and trends were studied. Analysis was performed for stroke overall and by sex and age-group as well as by stroke type. RESULTS: Estimated average annual rates of hospitalized stroke decreased from 24.9/10 000 in 2004 to 19.5/10 000 in 2013. The age and sex-adjusted rates ratio (95% confidence interval) for hospitalized stroke overall was 0.82 (0.76-0.89) for 2007, 0.71 (0.65-0.77) for 2010, and 0.72 (0.66-0.78) for 2013 compared with 2004. Severity on admission decreased over time: rates (95% confidence interval) of severe stroke (National Institutes of Health Stroke Scale score of ≥11) decreased from 27% (25%-29%) in 2004 to 19% (17%-21%) in 2013, whereas rates (95% confidence interval) of minor stroke (National Institutes of Health Stroke Scale score of ≤5) increased from 46% (44%-49%) in 2004 to 60% (57%-62%) in 2013 (P<0.0001). Findings were consistent by sex, age-group, and stroke type. CONCLUSIONS: Based on our national data, rates of hospitalized stroke and severity of stroke on admission have decreased from 2004 to 2013 overall and by stroke type, in men and women. Despite the observed declines in rates and severity, stroke continues to place a considerable burden to the Israeli health system.
