Sex differences in cerebral aneurysm occurrence and characteristics have been well described. Although sex differences in outcomes following ischemic stroke have been identified, the effect of sex on outcomes following hemorrhagic stroke, and in particular, aneurysm treatment has been less studied. We describe the current state of knowledge regarding the impact of sex on treatment and outcomes of cerebral aneurysms. Although prior studies suggest that aneurysm prevalence and progression may be related to sex, we did not find clear evidence that outcomes following subarachnoid hemorrhage vary based on sex. Last, we identify areas for future research that could enhance understanding of the role sex plays in this context.

Abstract Hemorrhagic stroke (HS) is a major cause of death and disability worldwide, despite being less common, it presents more aggressively and leads to more severe sequelae than ischemic stroke. There are two types of HS: Intracerebral Hemorrhage (ICH) and Subarachnoid Hemorrhage (SAH), differing not only in the site of bleeding, but also in the mechanisms responsible for acute and subacute symptoms. This is a systematic review of databases in search of works of the last five years relating to the comprehension of both kinds of HS. Sixty two articles composed the direct findings of the recent literature and were further characterized to construct the pathophysiology in the order of events. The road to the understanding of the spontaneous HS pathophysiology is far from complete. Our findings show specific and individual results relating to the natural history of the disease of ICH and SAH, presenting common and different risk factors, distinct and similar clinical manifestations at onset or later days to weeks, and possible complications for both.

Background: Recent nursing initiatives encourage early mobilization of neurocritical care patients, but whether this intervention can be safely generalized to acute stroke is debatable. We performed a systematic review of findings from recent studies to provide direction for patient management and future research. Methods: An exhaustive literature search was performed in Medline, SCOPUS and the Cochrane Central Register of Controlled Trials to identify published clinical trial research using a very early mobility intervention (within 24 hours) in acute ischemic stroke patients. The primary efficacy outcome supporting the search was neurologic disability reduction or improved functional outcomes, and the primary safety outcome was neurologic deterioration. Studies were critically reviewed for inclusion by 3 separate investigators, findings were synthesized, and an overall recommendation for very early mobilization use in acute stroke was assigned according to GRADE criteria. Results: We initially identified 12 papers focused on early mobilization in acute stroke; of these, 6 observational studies were excluded, 1 study was excluded due to an ambiguous population, and 3 studies were excluded due to first initial mobilization out of bed occurring greater than 24 hours after admission. Two prospective randomized outcome blinded evaluation (PROBE) studies were retained, consisting of a total 2160 patients; ischemic stroke subtype was not disclosed in either study, limiting an understanding of the impact of very early mobilization on small versus large artery occlusion. Slower mobilization occurring beyond the first 24 hours was associated with higher rates of favorable outcome (mRS 0-2) at 90 days, whereas very early mobilization within the first 24 hours was associated with a number needed to harm of 25. Conclusions: In acute stroke, evidence supports a rested approach to care within the first 24 hours of hospitalization (GRADE: Strong recommendation, high quality of evidence). Similar to acute myocardial infarction, vascular insufficiency experienced in stroke likely warrants a more guarded approach to mobility. Additional studies exploring timing beyond 24 hours and dose of mobility interventions are warranted in discreet populations.

Background The association between systemic hypertension and cerebrovascular disease is well documented. However, the impact of pulmonary hypertension (PH) on acute ischemic stroke outcomes is unknown despite PH being recognized as a risk factor for acute ischemic stroke. We aimed to determine the association between PH and adverse in‐hospital outcomes after acute ischemic stroke, as well as whether there are sex differences in this association. Methods and Results Acute ischemic stroke admissions from the US National Inpatient Sample between October 2015 and December 2017 were included. The relationship between PH and outcomes (mortality, prolonged hospitalization >4 days, and routine home discharge) was analyzed using logistic regressions adjusting for demographics, comorbidities, and revascularization therapies. Interaction terms between PH and sex and age groups were also included. A total of 221 249 records representative of 1 106 045 admissions were included; 2.9% of patients had co‐morbid PH, and 35.34% of those were male. PH was not associated with in‐hospital mortality (odds ratio [OR], 0.96; 95% CI, 0.86–1.09) but was associated with increased odds of prolonged hospitalization (OR, 1.15; 95% CI, 1.09–1.22) and decreased odds of routine discharge (OR, 0.87; 95% CI, 0.81–0.94) for both sexes. Older patients with PH were significantly less likely to be discharged routinely ( P =0.028) than their younger counterparts. Compared with female patients with PH, men were 31% more likely to die in hospital ( P =0.024). Conclusions PH was not significantly associated with in‐hospital mortality but was associated with prolonged hospitalization and adverse discharge status. Male patients with PH were more likely to die in hospital than female patients.

Arthritis is ranked among the top causes of disability in the United States and worldwide. Despite recent improvements in medications and medical treatment, there is no known cure for arthritis. Providing evidence-based psychoeducation and counseling services to people with arthritis lessens the impact of pain-related symptoms and disability on the individual and society. The purpose of this chapter is to provide an overview of the most common arthritic conditions, co-occurring physical conditions, and psychosocial factors associated with arthritis. Barriers to self-management and existing self-management programs are also discussed along with the current state of scientific evidence. The chapter concludes with some questions for future research.

ABSTRACT Stroke is the leading cause of long term disability in developed countries and one of the top causes of mortality worldwide. The past decade has seen substantial advances in the diagnostic and treatment options available to minimize the impact of acute ischemic stroke. The key first step in stroke care is early identification of patients with stroke and triage to centers capable of delivering the appropriate treatment, as fast as possible. Here, we review the data supporting pre-hospital and emergency stroke care, including use of emergency medical services protocols for identification of patients with stroke, intravenous thrombolysis in acute ischemic stroke including updates to recommended patient eligibility criteria and treatment time windows, and advanced imaging techniques with automated interpretation to identify patients with large areas of brain at risk but without large completed infarcts who are likely to benefit from endovascular thrombectomy in extended time windows from symptom onset. We also review protocols for management of patient physiologic parameters to minimize infarct volumes and recent updates in secondary prevention recommendations including short term use of dual antiplatelet therapy to prevent recurrent stroke in the high risk period immediately after stroke. Finally, we discuss emerging therapies and questions for future research.

OBJECTIVEAlthough cigarette smoking is one of the strongest risk factors for cerebral aneurysm development and rupture, there are limited data evaluating the impact of smoking on outcomes after aneurysmal subarachnoid hemorrhage (SAH). Additionally, two recent studies suggested that nicotine replacement therapy was associated with improved neurological outcomes among smokers who had sustained an SAH compared with smokers who did not receive nicotine.METHODSPatients who underwent endovascular or microsurgical repair of a ruptured cerebral aneurysm were extracted from the Nationwide Inpatient Sample (NIS, 2009–2011) and stratified by cigarette smoking. Multivariable logistic regression analyzed in-hospital mortality, complications, tracheostomy or gastrostomy placement, and discharge to institutional care (a nursing or an extended care facility). Additionally, the composite NIS-SAH outcome measure (based on mortality, tracheostomy or gastrostomy, and discharge disposition) was evaluated, which has been shown to have excellent agreement with a modified Rankin Scale score greater than 3. Covariates included in regression constructs were patient age, sex, race/ethnicity, insurance status, socioeconomic status, comorbidities (including hypertension, drug and alcohol abuse), the NIS-SAH severity scale (previously validated against the Hunt and Hess grade), treatment modality used for aneurysm repair, and hospital characteristics. A sensitivity analysis was performed matching smokers to nonsmokers on age, sex, number of comorbidities, and NIS-SAH severity scale score.RESULTSAmong the 5784 admissions evaluated, 37.1% (n = 2148) had a diagnosis of tobacco use, of which 31.1% (n = 1800) were current and 6.0% (n = 348) prior tobacco users. Smokers were significantly younger (mean age 51.4 vs 56.2 years) and had more comorbidities compared with nonsmokers (p < 0.001). There were no significant differences in mortality, total complications, or neurological complications by smoking status. However, compared with nonsmokers, smokers had significantly decreased adjusted odds of tracheostomy or gastrostomy placement (11.9% vs 22.7%, odds ratio [OR] 0.63, 95% confidence interval [CI] 0.51–0.78, p < 0.001), discharge to institutional care (OR 0.71, 95% CI 0.57–0.89, p = 0.002), and a poor outcome (OR 0.65, 95% CI 0.55–0.77, p < 0.001). Similar statistical associations were noted in the matched-pairs sensitivity analysis and in a subgroup of poor-grade patients (the upper quartile of the NIS-SAH severity scale).CONCLUSIONSIn this nationwide study, smokers experienced SAH at a younger age and had a greater number of comorbidities compared with nonsmokers, highlighting the negative ramifications of cigarette smoking among patients with cerebral aneurysms. However, smoking was also associated with paradoxical superior outcomes on some measures, and future research to confirm and further understand the basis of this relationship is needed.

OBJECTIVE The impact of combined practices on the outcomes of unruptured cerebral aneurysm coiling remains an issue of debate. The authors investigated the association of combined open and endovascular expertise with the outcomes of unruptured cerebral aneurysm coiling. METHODS The authors performed a cohort study of 100% of Medicare fee-for-service claims data for elderly patients who underwent endovascular coiling for unruptured cerebral aneurysms between 2007 and 2012. To control for confounding, the authors used propensity score conditioning, with mixed effects to account for clustering at the hospital referral region level. RESULTS During the study period, there were 11,716 patients who underwent endovascular coiling for unruptured cerebral aneurysms and met the inclusion criteria. Of these, 1186 (10.1%) underwent treatment performed by hybrid neurosurgeons, and 10,530 (89.9%) by proceduralists who performed only endovascular coiling. Multivariable regression analysis with propensity score adjustment demonstrated a lack of association of combined practice with 1-year postoperative mortality (OR 0.84; 95% CI 0.58–1.23), discharge to rehabilitation (OR 1.0; 95% CI 0.66–1.51), 30-day readmission rate (OR 1.07; 95% CI 0.83–1.38), and length of stay (adjusted difference, 0.41; 95% CI −0.26 to 1.09). Higher procedural volume was independently associated with improved outcomes. CONCLUSIONS In a cohort of Medicare patients, the authors did not demonstrate a difference in mortality, discharge to rehabilitation, readmission rate, and LOS between hybrid neurosurgeons and proceduralists performing only endovascular coiling.
