Background and Aims: Contemplating the use of N-acetylcysteine as a neuroprotectant, with dextran as an antithrombotic for patients with NIHSS less than or equal to 5, we quantified treatment-relevant clinical characteristics of a sample of this patient population at a single stroke center over one year.
Method(s): Patients with NIHSSResult(s): One-hundred twenty-eight of 310 (41%) patients with ischemic stroke had NIHSSConclusion(s): Minor stroke symptoms may not be captured by the current NIHSS. This population rarely had renal or hepatic failure, making them good candidates for combination N-acetylcysteine and dextran

BACKGROUND AND PURPOSE/OBJECTIVE:Patients with intracerebral hemorrhage (ICH) frequently present with hypertension, but it is unclear if this is due to pre-existing hypertension (prHTN) or to the bleed itself or associated pain. We sought to assess the relationship between prHTN and admission systolic blood pressure (aBP) and bleed severity. METHODS:We retrospectively assessed the relationship between prHTN and aBP and NIHSS in patients with ICH at 3 institutions. RESULTS:Of 251 patients, 170 (68%) had prHTN based on history of hypertension/antihypertensive use. Median aBP was significantly higher in those with prHTN (155 mm Hg (IQR 135-181) versus 139 mm Hg (IQR 124-158), P < .001). Patients with left ventricular hypertrophy (LVH) on electrocardiogram (ECG) or transthoracic echocardiogram (TTE) had significantly higher aBP than those without LVH (median aBP 195 mm Hg (IQR 155-216) for patients with LVH on ECG versus 147 mm Hg (IQR 129-163) for patients with no LVH on ECG, P < .001; median aBP 181 mm Hg (IQR 153-214) for patients with LVH on TTE versus 152 mm Hg (IQR 137-169) for patients with no LVH on TTE, P = .01). prHTN was associated with a higher median NIHSS (11 (IQR 3-20) for patients with history of hypertension/antihypertensive use versus 6 (IQR 1-14) for patients without this history (P = .02); 9 (IQR 3-19) versus 5 (IQR 2-13) for patients with/without LVH on ECG (P = .085); and 10 (IQR 5-18) versus 5 (IQR 1-13) for patients with/without LVH on TTE (P = .046). CONCLUSIONS:Patients with ICH who have prHTN have higher aBP and NIHSS, suggesting that prHTN may worsen reactive hypertension in the setting of ICH.

Introduction The 5 seminal mechanical thrombectomy (MT) trials had a median age of 68 years. Though some of these trials included nonagenarians, there is little data on their outcomes. We aimed to compare the procedural, discharge outcomes and complications, of MT for acute ischemic stroke (AIS) in nonagenarians versus younger patients(<=69) Methods Patients with AIS admitted to two comprehensive stroke centers were enrolled prospectively in a registry. Rates of MT were compared between nonagenarians vs <=69. Among those who underwent MT, procedural outcomes, complications, and discharge disposition were compared in propensity scorematched groups (matched for NIHSS, pre-stroke mRS, IV-tPA administration and T IG grade>=2b) of nonagenarians to patients<=69. Good discharge disposition was defined as a discharge to home/acute rehabilitation. Results Of the 3010 AIS patients, 46/297 (16%) nonagenarians underwent MT compared to 159/1337 (12%) patients <=69 (P=0.091) with TICI>=2b of 89% vs 94%; p=0.238 respectively. 78 patients (N=39 >=90, N=39 <69) were propensity score-matched with a median admission NIHSS of 22 and 19, and median ASPECTS of 9 and 9, respectively (both P>0.05). Those <69 more often had Ml occlusions than nonagenarians (84% vs 50%, P=0.035), whereas ICA (10% vs 13%, p=0.76), and M2 (21% vs 43%, p=0.19) occlusions were similar between the two groups. Time to groin puncture (100+/-65 vs 76+/-34; p=0.124), revascularization time (134+/-72 vs 110+/-54; p=0.145), complication rates (0 vs 5.1%; p=0.494) and inhospital deaths (11% vs 24%; p=0.155) were similar among the two groups. 44% of nonagenarians had good discharge disposition, compared to 51% of patients <69 years (p=0.650) Conclusions We present one of the largest series of MT among nonagenarians with 89% successful recanalization rates. In propensity score analysis almost half of nonagenarians (44%) were discharged to home/rehab, which is comparable to a younger cohort (51%). Aggressive management is warranted in the oldest of the old

BACKGROUND AND PURPOSE/OBJECTIVE:The relationship between in-hospital hyperglycemia and neurological outcome after intracerebral hemorrhage (ICH) is not well studied. METHODS:We analyzed the relationships between pre-hospital and hospital variables including highest in-hospital glucose (HIHGLC) and discharge Glasgow Coma Scale (GCS), discharge Modified Rankin Scale (MRS) and 3-month MRS using a single-institution cohort of ICH patients between 2013 and 2015. RESULTS:There were 106 patients in our sample. Mean HIHGLC was 154 ± 58mg/dL for patients with discharge GCS of 15 and 180 ± 57mg/dL for patients with GCS < 15; 146 ± 55mg/dL for patients with discharge MRS 0-3 and 175 ± 58mg/dL for patients with discharge MRS 4-6; and 149 ± 52mg/dL for patients with 3-month MRS of 0-3 and 166 ± 61mg/dL for patients with 3-month MRS of 4-6. On univariate analysis, discharge GCS was associated with HIHGLC (P = .01), age (P = .006), ICH volume (P = .008), and length of stay (LOS) (P = .01); discharge MRS was associated with HIHGLC (P < .001), age (P < .001), premorbid MRS (P = .046), ICH volume (P < .001), and LOS (P < .001); and 3-month MRS was associated with HIHGLC (P = .006), discharge MRS (P < .001), age (P = .001), sex (P = .002), ICH volume (P = .03), and length of stay (P = .004). On multivariate analysis, discharge GCS only had a significant relationship with ICH volume (odds ratio [OR] .949, .927-.971); discharge MRS had a significant relationship with age (OR 1.043, 1.009-1.079), premorbid MRS (OR 2.622, 1.144-6.011), and ICH volume (OR 1.047, 1.003-1.093); and 3-month MRS only had a significant relationship with age (OR 1.039, 1.010-1.069). CONCLUSIONS:The relationship between in-hospital hyperglycemia and neurological outcomes in ICH patients was meaningful on univariate, but not multivariate, analysis. Glucose control after ICH is important.
