Hypertension is a Leading Cause of Nontraumatic Intracerebral Hemorrhage in Young Adults.

OBJECTIVE: To evaluate the etiology and discharge outcome of nontraumatic intracerebral hemorrhage (ICH) in young adults admitted to a comprehensive stroke center. METHODS: A retrospective chart review was performed on patients with a discharge diagnosis of nontraumatic ICH admitted from 7/1/2011 to 6/30/2016. Data was collected on demographics, clinical history, ICH score, hemorrhage location, do-not-resuscitate (DNR) orders, likely etiology, and discharge disposition. Categorical data was reported as percentage. Chi-squared test was performed to evaluate association of location of ICH, etiology of ICH, and ICH score with the discharge outcome. RESULTS: Sixty-three patients met the study criteria, with mean age 35.4 ± 6.4 years including 26 (41%) women and 40 (64%) whites. Headache (65%) and change in mental status (48%) were the most common presenting symptoms. Hemorrhage was most commonly seen in the deep structures in 29 (46%) patients followed by lobar ICH in 14 (22%) patients. The most common etiology of ICH was hypertension in 23 (37%) patients, followed by vascular abnormalities in 18 (29%) patients. Forty-two (67%) had good outcome defined as discharge to home (n = 25) or acute inpatient rehabilitation (n = 17). Twenty-one (33%) patients had bad outcome with discharge to skilled nursing facility (n = 6), hospice (n = 1) or died in the hospital (n = 14). Hospital DNR orders were noted in 11 (18%) patients. Higher ICH score (P < .0001) and use of DNR orders (P < .0001) were associated with bad outcome. All 11 patients with DNR orders died in the hospital. Location or etiology of hemorrhage were not associated with discharge outcome. CONCLUSIONS: Hypertension, a modifiable risk factor, is a major cause of nontraumatic ICH in young adults. Aggressive management of hypertension is essential to halt the recent increased trends of ICH due to hypertension. Early DNR orders may need to be cautiously used in the hospital.

Dual-Antiplatelet Therapy May Not Be Associated With an Increased Risk of In-hospital Bleeding in Patients With Moderate or Severe Ischemic Stroke.

Background and Purpose: Dual antiplatelet therapy (DAPT), compared to single antiplatelet therapy (SAPT), lowers the risk of stroke or death early after TIA and minor ischemic stroke. Prior trials excluded moderate to severe strokes, due to a potential increased risk of bleeding. We aimed to compare in-hospital bleeding rates in SAPT and DAPT patients with moderate or severe stroke (defined by NIHSS ≥4). Methods: We performed a retrospective cohort study of ischemic stroke over a 2-year period with admission NIHSS ≥4. The primary outcome was symptomatic intracranial hemorrhage (ICH) with any change in NIHSS. Secondary outcomes included systemic bleeding and major bleeding, a composite of serious systemic bleeding and symptomatic ICH. We performed analyses stratified by stroke severity (NIHSS 4-7 vs. 8+) and by preceding use of tPA and/or thrombectomy. Univariate followed by multivariate logistic regression evaluated whether DAPT was independently associated with bleeding. Results: Of 377 patients who met our inclusion criteria, 148 received DAPT (39%). Symptomatic ICH was less common with DAPT compared to SAPT (0.7 vs. 6.4%, p < 0.01), as was the composite of major bleeding (2.1 vs. 7.6%, p = 0.03). Symptomatic ICH was numerically less frequent in the DAPT group, but not statistically significant, when stratified by stroke severity (NIHSS 4-7: 0 vs. 5.9%, p = 0.06; NIHSS 8+: 1.5 vs. 6.6%, p = 0.18) and by treatment with tPA and/or thrombectomy (Yes: 2.6 vs. 9.1%, p = 0.30; No: 0 vs. 2.9%, p = 0.25). DAPT was not associated with major bleeding in either the univariate or the multivariate regression. Conclusions: In this single center cohort, symptomatic ICH and the composite of serious systemic bleeding and symptomatic ICH was rare in patients on DAPT. Relative to single antiplatelet therapy DAPT was not associated with an increased risk of in-hospital bleeding in patients with moderate and severe ischemic stroke.

STN vs. GPi deep brain stimulation for tremor suppression in Parkinson disease: A systematic review and meta-analysis.

OBJECTIVE: To compare subthalamic nucleus (STN) deep brain stimulation (DBS) with globus pallidus interna (GPi) DBS for tremor suppression in Parkinson disease (PD). BACKGROUND: DBS is an effective surgical therapy that has been shown to provide significant benefit for motor symptoms in PD. Currently, two main structures targeted to treat motor complications in PD are the STN and GPi. Although some groups traditionally favor STN over GPi for tremor suppression, evidence demonstrating superiority in long-term tremor control is limited. METHODS: We performed a systematic review for all randomized trials comparing STN vs GPi DBS in PD that were published before March 2017. Five studies were examined in a random effects model meta-analysis. We conducted moderator variable analysis to determine if there was a treatment effect difference for STN versus GPi. RESULTS: We compared DBS ON versus OFF and found a significant overall standardized difference mean effect: Effect Size = 0.36; 95% CI = 0.316-0.395; P < 0.0001. These findings indicate that DBS reduced tremor symptoms in PD patients with a medium effect size. Moderator variable analysis of STN vs GPI revealed two significant standardized effect sizes: STN effect size = 0.38 and GPi effect size = 0.35. A Z-test showed that effect sizes between the STN and GPi were not significantly different (P = 0.56). CONCLUSIONS: DBS is effective in reducing tremor in PD patients regardless of stimulation target. However, the degree of tremor suppression in STN DBS versus GPi DBS was equivalent.
