We explored intraurban mobility of Tijuana, Mexico, injection drug users (IDUs). In 2005, 222 IDUs underwent behavioral surveys and infectious disease testing. Participants resided in 58 neighborhoods, but regularly injected in 30. From logistic regression, "mobile" IDUs (injecting ≥3 km from their residence) we…

Synchronous development of a second primary cancer in patients with esophageal squamous cell carcinoma was reported in 2.73%-11% of the cases. Although the synchronous association between esophageal and renal cancer is very rare, an increasingly number of cases is reported in medical literature. This study's aim is to…

BACKGROUND: Primary neuromotor abnormalities are thought to be a manifestation of the brain pathology underlying the psychotic illness; however, their causes and consequences are poorly understood. The study's aim was to examine the prevalence and correlates of neuromotor abnormalities in a sample of neuroleptic-naive…

Many preventive healthcare procedures are widely recognized as cost-effective but have relatively low utilization rates in the US. Because preventive care is a present-period investment with a future-period expected financial return, enrollee turnover among private insurers lowers the expected return of this investment…

Three experiments tested whether the Stroop color-naming effect is a consequence of word recognition's being automatic or of the color word's capturing visual attention. In Experiment 1, a color bar was presented at fixation as the color carrier, with color and neutral words presented in locations above or below the co…

OBJECTIVE: The study's aim is to evaluate the role of Perineal Ultrasound (PU) in the outcome assessment for the TVT procedures and correlate PU findings to clinical outcomes in a subgroup of patients with postoperative voiding obstructive complaints. MATERIALS AND METHODS: From 2001 to 2005, 100 patients were evaluat…

This paper presents an evolving user-oriented model of Internet health information seeking (IS) based on qualitative data collected from 22 lung cancer (LC) patients and caregivers. This evolving model represents information search behavior as more highly individualized, complex, and dynamic than previous models, inclu…

BACKGROUND AND OBJECTIVES: Traditional indices of continuity of care typically capture frequency of physician visits but lack information regarding how patients themselves perceive continuity of care. The present study's objectives were (1) to examine the meaning of continuity of care from the perspective of patients w…

Robins, Kellam, and others found robust evidence linking youthful aggression and deviance to later illicit drug use. Some investigators favor the interpretation that drug use is just one manifestation or complication of a more general problem behavior syndrome or conduct disorder. In this work, we test the complementar…

Motor unit action potentials (MUAPs) recorded from the same motor unit at two distances along the biceps brachii muscle with monopolar needle electrodes at high amplifier gains (20 microV/division) and averaged 2000-3000 times reveal total potential durations of 39.6 +/- 4.6 ms. In addition, the terminal segment for ea…

Possibilities and limits of the method for timing an intracranial hemorrhage by means of the HbA/HbF erythrocyte ratio are investigated in six newborns. The effect of labeling HbF erythrocyte containing newborn blood by transfusion and exchange transfusion of HbA erythrocyte containing donor blood as well as "self-labe…

OBJECTIVE: To estimate the cost-effectiveness of using a carboxymethylcellulose dressing containing ionic silver, ethylenediaminetetraacetic acid and benzethonium chloride (CISEB; Aquacel Ag+ Extra, Convatec Ltd., UK) compared with a dialkylcarbamoyl chloride-coated dressing (DACC; Cutimed Sorbact, Essity, Germany) in…

The natural product MGN-3 (Biobran) is a defatted, partially hydrolysed rice bran-derived hemicellulose enzymatically modified with an extract of. It has a high proportion of arabinoxylan. It has a protective action against intracerebroventricular streptozotocin-induced murine sporadic Alzheimer's disease and reverses…

BackgroundPoststroke depression (PSD), with an approximately one third prevalence in stroke patients, is associated with increased morbidity and mortality. This study investigated the relationship between serum brain-derived neurotrophic factor (BDNF) levels and early-onset PSD, along with other clinical variables.Meth…
