OBJECTIVE This study evaluates the pattern of neuropsychological deficits and their association with clinical symptomatology and social functioning in individuals identified as ultra-high-risk (UHR) for psychosis. METHODS A sample of 45 UHR individuals was identified using the Structured Interview for Prodromal Syndromes (SIPS) from consecutive referrals(More)
This study aims to establish preliminary validity of the Prodromal Questionnaire (PQ), a 92-item self-report screening measure for prodromal and psychotic symptoms. Adolescents and young adults (N = 113) referred to a prodromal psychosis research clinic completed the PQ and the Structured Interview for Prodromal Syndromes (SIPS [Miller, T.J., McGlashan,(More)
BACKGROUND Neurocognitive deficits and symptoms of schizotypal personality disorder are both elevated in the first-degree relatives of schizophrenic patients, but their relationship to each other and their potential common genetic source remain unclear. METHODS Fifty unaffected co-twins of schizophrenic patients and 123 control twins were assessed with a(More)
This study was designed to identify the types of neuropsychological deficits that are unique to familial and nonfamilial forms of schizophrenia. Seventy-two patients who met Research Diagnostic Criteria for schizophrenia or schizoaffective disorder, mainly schizophrenic, were divided into two groups on the basis of the presence or absence of a family(More)
This study assessed the rates of self-reported "prodromal" psychotic symptoms and related distress in a college population. 1020 students completed the Prodromal Questionnaire (PQ), a self-report screening measure for psychosis risk. Participants' responses were highly similar to the responses of non-psychotic-spectrum patients in the original PQ validation(More)
OBJECTIVE Recently developed research criteria have made it possible to identify adolescents at imminent risk for psychosis. However, the array of symptomatology in these patients is broad and has not yet been systematically characterized using established diagnostic and assessment tools. METHOD The authors characterized 24 adolescent research(More)
Until recently, methicillin-resistant Staphylococcus aureus (MRSA) has caused predominantly healthcare-associated infections. We studied MRSA infections and overall skin and soft tissue infections (SSTIs) in outpatients receiving care at the Baltimore Veterans Affairs Medical Center Emergency Care Service during 2001-2005. We found an increase in MRSA(More)
BACKGROUND HIV patients are at increased risk of development of infections and infection-associated poor health outcomes. We aimed to 1) assess the prevalence of USA300 community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) among HIV-infected patients with S. aureus bloodstream infections and. 2) determine risk factors for infective(More)
—Monitoring bridges with wireless sensor networks aids in detecting failures early, but faces power challenges in ensuring reasonable network lifetimes. Recharging select nodes with Unmanned Aerial Vehicles (UAVs) provides a solution that currently can recharge a single node. However, questions arise on the effectiveness of a limited recharging system, the(More)
