Acute ischemic stroke (AIS) is a leading cause of mortality that occurs when an embolus becomes lodged in the cerebral vasculature and obstructs blood flow in the brain. The severity of AIS is determined by the location and how extensively emboli become lodged, which are dictated in large part by the cerebral flow and the dynamics of embolus migration which are difficult to measure in AIS patients. Computational fluid dynamics (CFD) can be used to predict the patient-specific hemodynamics and embolus migration and lodging in the cerebral vasculature to better understand the underlying mechanics of AIS.

Tai Chi has been shown to elicit numerous positive effects on health and well-being. In this study, we examined reactive postural control after sudden unloading horizontal perturbations, which resembled situations encountered during Tai Chi. The study involved 20 participants, 10 in the Tai Chi group (age: 37.

The withdrawal of the serotype 2 component of oral poliovirus vaccine (OPV2) was implemented in April 2016 to stop VDPV2 emergence and secure eradication of all serotype 2 poliovirus. Globally, children born after this date have limited immunity to prevent transmission.

The IMG's inclusive, transparent, and partnership-focused approach proved an effective means of leveraging the comparative and complementary strengths of each IMG member agency. This article outlines 10 key factors behind the IMG's success, providing a potential set of guiding principles for the establishment and implementation of other interagency collaborations and initiatives beyond the polio sphere.

Rotary has contributed more than $1.61 billion for the global eradication of polio and has committed to provide an additional $35 million each year until 2018 (all dollar amounts represent US dollars).

Methods: This case-control study included 85 patients diagnosed with PDD and 85 age- and gender-matched nonpsychotic psychiatric patients without PDD. Data were collected from the patients' electronic medical records and included demographic and psychiatric parameters, as well as data on smoking, alcohol, and cannabis use.
Objective: The purpose of this study was to determine if the known side effects of lithium in adults may be generalized to younger patients with psychiatric disorders.
Methods: A retrospective naturalistic study design was used. Data were collected from the database of a tertiary pediatric medical center covering the years 1994-2010.

The objective of this study was to assess the response of subsyndromal separation anxiety (SSSA) symptoms to methylphenidate (MPH) treatment in patients with attention-deficit/hyperactivity disorder (ADHD). A group of patients with ADHD and SSSA (n=42), aged 8-17 years, received 12 weeks of MPH treatment. The severity of SSSA symptoms was assessed using appropriate scales including the Screen for Child Anxiety Related Emotional Disorders and the specially designed Child and Adolescent Separation Anxiety Scale (CASAS).

Twenty-one ADHD patients with SP, aged between 8 and 18 years, received 12 weeks of MPH treatment. The severity of SP symptoms were assessed by the Liebowitz Social Anxiety Scale for Children and Adolescents (LSAS-CA), and the severity of ADHD symptoms was assessed by the ADHD Rating Scale at baseline and at endpoint.

Both are often comorbid with autistic spectrum disorder (ASD). We evaluated the effectiveness of reboxetine treatment in pediatric patients with ASD with symptoms of depression and ADHD.

The objective of this study is to investigate whether other TTF values are more predictive of the saphenous vein graft (SVG) failure and/or clinical outcomes.
Methods: This is a case control retrospective study of 65 SVGs from 44 patients from GRIIP.
Background: Children with autistic spectrum disorder (ASD) have difficulties understanding and using nonverbal communication. Handshaking is an expressive gesture that requires adequate skills for social interaction and, because of its highly emotional characteristic for patients with ASD, may reflect their ability for social responsiveness. Unlike eye contact or complex social behavior, this gesture has not been studied in the past.

Cardiac ventricular late potentials (LPs) represent delayed ventricular activation that might predispose to fatal ventricular arrhythmias and SCD in cardiac patients. LPs have not previously been measured in children with attention deficit/hyperactivity disorder (ADHD).

Stimulants, including methylphenidate, as well as non-stimulants, have shown efficacy in treating adult ADHD. Comparative, double blind, placebo controlled studies, in adults with ADHD, demonstrate good efficacy and safety profile.

Method: Eleven adolescent patients (8 boys and 3 girls) diagnosed with ASD, aged 13 to 17 years, were treated with quetiapine in an open-label study over an 8-week period.
Objectives: Trichotillomania (TTM) is a heterogenic mental disorder with a high rate of comorbidity and stressful life events (SLEs). Serotonergic and dopaminergic dysfunction are implicated in the pathophysiology of TTM. As in other impulse control disorders, increased prevalence of attention-deficit/hyperactivity disorder (ADHD) is reported in patients with TTM as well.

Patients who received clopidogrel prior to coronary bypass surgery are at increased risk for bleeding that must be balanced with risk of ongoing ischemia if coronary artery bypass grafting is delayed. This study aimed to evaluate the impact of clopidogrel on mortality and major bleeding in patients undergoing urgent coronary bypass surgery. We reviewed 451 consecutive patients who underwent urgent isolated coronary bypass surgery; 262 had not received clopidogrel, whereas 189 received clopidogrel < or = 5 days preoperative.

We assessed the impact of methylphenidate (MPH)treatment on the smoking behavior of adolescent girls with ADHD/borderline personality disorder (BPD).
Method: Twelve female adolescent smokers with ADHD/BPD aged 14to 19 years were treated with MPH for an 8-week period.
Recent studies reported symptomatic overlap between attention deficit/hyperactivity disorder (ADHD) and borderline personality disorder (BPD). Methylphenidate (MPH) is the most efficient treatment for ADHD. We assessed the efficacy and tolerability of MPH treatment in adolescent females who met the Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV criteria for both disorders.
