Background— We examined the risk of stroke or systemic embolism (SSE) conferred by heart failure (HF) and left ventricular systolic dysfunction (LVSD) in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation Trial (ARISTOTLE), as well as the effect of apixaban versus warfarin. Methods and Results— The risk of a number of outcomes, including the composite of SSE or death (to take account of competing risks) and composite of SSE, major bleeding, or death (net clinical benefit) were calculated in 3 patient groups: (1) no HF/no LVSD (n=8728), (2) HF/no LVSD (n=3207), and (3) LVSD with/without symptomatic HF (n=2736). The rate of both outcomes was highest in patients with LVSD (SSE or death 8.06; SSE, major bleeding, or death 10.46 per 100 patient-years), intermediate for HF but preserved LV systolic function (5.32; 7.24), and lowest in patients without HF or LVSD (1.54; 5.27); each comparison P <0.0001. Each outcome was less frequent in patients treated with apixaban: in all ARISTOTLE patients, the apixaban/warfarin hazard ratio for SSE or death was 0.89 (95% confidence interval, 0.81–0.98; P =0.02); for SSE, major bleed, or death it was 0.85 (0.78–0.92; P <0.001). There was no heterogeneity of treatment effect across the 3 groups. Conclusions— Patients with LVSD (with/without HF) had a higher risk of SSE or death (but similar rate of SSE) compared with patients with HF but preserved LV systolic function; both had a greater risk than patients without either HF or LVSD. Apixaban reduced the risk of both outcomes more than warfarin in all 3 patient groups. Clinical Trial Registration— URL: http://www.clinicaltrials.gov . Unique identifier: NCT00412984.

The use of 2-way audiovisual telemedicine technology for the delivery of acute stroke care is well established in the literature and is a growing practice. The use of such technology for neurologic consultation outside the cerebrovascular specialty has been reported to a variable extent across most disciplines within the field of neurology, including that of the neurohospitalist medicine. A systematic review of these reports is lacking. Hence, the main purpose of this study was to conduct a systematic review of the literature on teleneurologic consultation in hospital neurology. The databases Ovid MEDLINE, EMBASE, PsychINFO, CINAHL, and Cochrane were used as data sources and were searched with key words “teleneurology” and its numerous synonyms and cognates. These key words were cross-referenced with subspecialties of neurology. The studies were included for further review only if the title or the abstract indicated that the study made use of 2-way audiovisual communication to address a neurologic indication. This search yielded 6625 abstracts. By consensus between the 2 investigators, 688 publications met the criteria for inclusion and further review. Four of those citations directly pertained to the inpatient hospital neurologic consultation. Each of the 4 relevant articles was scored with a novel rubric scoring functionality, application, technology, and evaluation phase. A subspecialty category score was calculated by averaging those scores. The use of 2-way audiovisual technology for general neurologic consultation of hospital inpatients, beyond stroke-related care, is promising, but the evidence supporting its routine use is weak. Further studies on reliability, validity, safety, efficacy, and cost-effectiveness are encouraged.

Selective Mutism (SM) is a highly impairing disorder which typically presents upon entry to school and affects approximately 0.7% of children. Despite its impact on social and academic development, it is a difficult disorder to treat and there is a small evidence base for behavioral treatment. Preliminary evidence suggests that behavioral treatment focused on exposure to social interactions, social skill building, and involvement of caregivers in treatment may be promising. This article presents two cases of early childhood SM to demonstrate the importance of tailored treatment implementation to meet the individual needs of each family and help children resume typical social development.
