BackgroundBlack and Hispanic stroke survivors experience higher rates of recurrent stroke than whites. This disparity is partly explained by disproportionately higher rates of uncontrolled hypertension in these populations. Home blood pressure telemonitoring (HBPTM) and nurse case management (NCM) have proven efficacy in addressing the multilevel barriers to blood pressure (BP) control and reducing BP. However, the effectiveness of these interventions has not been evaluated in stroke patients. This study is designed to evaluate the comparative effectiveness, cost-effectiveness and sustainability of these two telehealth interventions in reducing BP and recurrent stroke among high-risk Black and Hispanic stroke survivors with uncontrolled hypertension.Methods/DesignA total of 450 Black and Hispanic patients with recent nondisabling stroke and uncontrolled hypertension are randomly assigned to one of two 12-month interventions: 1) HBPTM with wireless feedback to primary care providers or 2) HBPTM plus individualized, culturally-tailored, telephone-based NCM. Patients are recruited from stroke centers and primary care practices within the Health and Hospital Corporations (HHC) Network in New York City. Study visits occur at baseline, 6, 12 and 24 months. The primary outcomes are within-patient change in systolic BP at 12 months, and the rate of stroke recurrence at 24 months. The secondary outcome is the comparative cost-effectiveness of the interventions at 12 and 24 months; and exploratory outcomes include changes in stroke risk factors, health behaviors and treatment intensification. Recruitment for the stroke telemonitoring hypertension trial is currently ongoing.DiscussionThe combination of two established and effective interventions along with the utilization of health information technology supports the sustainability of the HBPTM + NCM intervention and feasibility of its widespread implementation. Results of this trial will provide strong empirical evidence to inform clinical guidelines for management of stroke in minority stroke survivors with uncontrolled hypertension. If effective among Black and Hispanic stroke survivors, these interventions have the potential to substantially mitigate racial and ethnic disparities in stroke recurrence.Trial registrationClinicalTrials.gov NCT02011685.

Although computed tomography (CT) and magnetic resonance imaging scans often appear normal after mild head trauma, many patients experience attentional or other cognitive disturbances that are difficult to quantify by neuropsychological testing in the absence of a premorbid profile. Within 2 days of mild head trauma, 14 patients with normal-appearing brain CTs were studied with single-photon emission computed tomography (SPECT). They were compared to 15 normal control subjects and to 12 patients with mild human immunodeficiency virus (HIV) encephalopathy. Ten of 14 head trauma patients were separated from the normal control subjects by both independent readers, blinded to the clinical diagnosis. None of the SPECT results from normal control subjects were "read" as trauma. Trauma could not be differentiated from HIV encephalopathy. The observed percentage agreement between raters was 0.83 (kappa = 0.72). SPECT is more sensitive than CT in detecting brain injury after mild head trauma.
Objective This study is aimed at facilitating clinician understanding of factors associated with postbariatric surgery neuropathic pain (PBSNP) and discussing the evidence base for management options. Design A case report and systematic literature review. Methods A search was conducted of PubMed, MEDLINE, Google Scholar, EMBASE, Psych Info, and Cochrane Database of Reviews for articles published between 1985 and 2013 on neuropathy, pain, and pharmacokinetics associated with postbariatric surgery. Results The epidemiology of PBSNP has not been well established, and current therapeutic options are not evidence based. Available data indicate up to 33% incidence of pain in patients with neuropathy after bariatric surgery, resulting in significant decreases in quality of life and increases in health care costs. Pathophysiologic mechanisms underlying PBSNP are unclear, and the natural course is variable, with some patients experiencing spontaneous improvement when nutritional deficiency is identified and corrected. Early identification of nutritional deficiency along with glycemic and lipid control may prevent or partially reverse postsurgical neuropathy and modulate PBSNP. Conclusions A better understanding of the peripheral and central mechanisms resulting in PBSNP is likely to promote the development of targeted and effective treatments.
