Delayed (diagnosis of) ICH within 24 h is very rare in mTBI patients on anticoagulants after reportedly normal initial CT. Routine hospitalization of these patients seems unwarranted when the initial cranial CT is scrupulously evaluated.
Centralization of intravenous thrombolysis (IVT) for acute ischemic stroke in high-volume centers is believed to improve the door-to-needle times (DNT), but limited data support this assumption. We examined the association between DNT and IVT volume in a large Dutch province. We identified consecutive patients treated with IVT between January 2009 and 2013. Based on annualized IVT volume, hospitals were categorized as low-volume (≤24), medium-volume (25–49) or high-volume (≥50). In logistic regression analysis, low-volume hospitals were used as reference category. Of 17,332 stroke patients from 11 participating hospitals, 1962 received IVT (11.3 %). We excluded 140 patients because of unknown DNT (n = 86) or in-hospital stroke (n = 54). There were two low-volume (total 101 patients), five medium-volume (747 patients) and four high-volume hospitals (974 patients). Median DNT was shorter in high-volume hospitals (30 min) than in medium-volume (42 min, p < 0.001) and low-volume hospitals (38 min, p < 0.001). Patients admitted to high-volume hospitals had a higher chance of DNT < 30 min (adjusted OR 3.13, 95 % CI 1.70–5.75), lower risk of symptomatic intracerebral hemorrhage (adjusted OR 0.39, 95 % CI 0.16–0.92), and a lower mortality risk (adjusted OR 0.45, 95 % CI 0.21–1.01), compared to low-volume centers. There was no difference in DNT between low- and medium-volume hospitals. Onset-to-needle times (ONT) did not differ between the groups. Hospitals in this Dutch province generally achieved short DNTs. Despite this overall good performance, higher IVT volumes were associated with shorter DNTs and lower complication risks. The ONT was not associated with IVT volume.
Clinical efficacy, safety and tolerability of quetiapine in the treatment of 23 hospitalized psychotic adolescents were evaluated retrospectively. Twelve patients were changed to quetiapine from another antipsychotic medication during their hospital stay. In these patients, CGI-S improved from 4.75+/-0.87 to 2.92+/-0.67 (observation period 3.7+/-1.6 months). The most common adverse events were transient tachycardia and sedation. Mild EPS occurred only in one patient under quetiapine monotherapy. Transaminase increases more than threefold above norm were observed in two patients. fT4 values were slightly below the norm in 67% of the cases. In 11 patients, quetiapine was initiated using a rapid titration schedule with high dosages in the acute phase. Receiving a mean maximum daily dose of 927+/-300 mg, CGI-S improved from 6.00+/-0.63 to 3.18+/-1.25 (observation period 2.9+/-1.8 months). Severe adverse events did not occur. Besides applying lorazepam temporarily in nine of the 11 patients, antipsychotic co-medication was not necessary in this group. In line with other studies, quetiapine may be considered as an effective treatment for adolescents with a severe psychotic disorder showing a favourable side-effect profile. Our preliminary data suggest that a rapid initiation with high doses could be a promising approach in acute psychotic adolescents.
Background Treatment outside office hours has been associated with increased workflow times for intravenous thrombolysis (IVT) in acute ischemic stroke (AIS). Limited data suggest that this "off-hours effect" also exists for endovascular treatment (EVT). We investigated this phenomenon in a well-organized acute stroke care region in the Netherlands. Methods Retrospective, observational cohort study of consecutive patients with AIS who received reperfusion therapy in the Greater Amsterdam Area, consisting of 14 primary stroke centers and 1 comprehensive stroke center (IVT: 2009-2015, EVT: 2014-2017). Office hours were defined as presentation during weekdays between 8 AM and 5 PM, excluding National Festive days. Primary outcome was door-to-treatment time (door-to-needle [DNT] for IVT, door-to-groin [DGT] for EVT). For DGT, we used the door time of the first hospital. Other outcomes were in-hospital mortality, modified Rankin Scale (mRS) score at 90 days and symptomatic intracranial hemorrhage (sICH). We performed multivariable linear and logistic regression analyses and used multiple imputation to account for missing values. Results In total, 59% (2450/4161) and 61% (239/395) of patients treated with IVT and EVT, respectively, presented outside office hours. Median DNT was minimally longer outside office hours (32 vs. 30 min, p = 0.024, adjusted difference 2.5 min, 95% CI 0.7-4.2). Presentation outside office hours was not associated with a longer DGT (median 130 min for both groups, adjusted difference 7.0 min, 95% CI − 4.2 to 18.1). Clinical outcome and sICH rate also did not differ. Conclusion Presentation outside office hours did not lead to clinically relevant treatment delays for reperfusion therapy in patients with AIS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
