We collected specimens from women who tested positive for Neisseria gonorrhoeae using the Gen-Probe APTIMA Combo 2 (AC2), and we performed confirmatory tests using a nucleic acid amplification test (NAAT) that targets alternate gonococcal nucleic acid sequences. Among 59,664 specimens, 280 (0.47%) had positive results using AC2; 265 of these specimens were tested using the confirmatory NAAT, of...
BACKGROUND India is witnessing a rising burden of type 2 diabetes mellitus. India's National Programme for Prevention and Control of Diabetes, Cancer, Cardiovascular diseases and Stroke recommends population-based screening and referral to primary health centre for diagnosis confirmation and treatment initiation. However, little is known about uptake of confirmatory tests among screen positives...
Differences between blacks and whites on cognitive ability tests have been attributed to a fundamental difference between these groups in general intelligence (or g, as it is denoted). The hypothesized difference in g gives rise to Spearman's hypothesis, which states that the differences in the means of the tests are related to the tests' factor loadings on g. Jensen has investigated this hypot...
OBJECTIVE To evaluate quality of a cervical cancer data system. METHODS Descriptive study on the completeness, validity, and sensitivity of data of the Cervical Cancer Data System (SISCOLO) in the State of Rio de Janeiro, Southeastern Brazil, based on the follow-up of a cohort of women, carried out between 2002 and 2006. The cohort consisted of 2,024 women living in communities served by the ...
Studies into the effects of stereotype threat (ST) on test performance have shed new light on race and sex differences in achievement and intelligence test scores. This article relates ST theory to the psychometric concept of measurement invariance, and shows that ST effects may be viewed as a source of measurement bias. As such, ST effects are detectable by means of multi-group confirmatory fa...
BACKGROUND Implantable cardioverter-defibrillators and cardiac resynchronization therapy defibrillators have relied on multiple ventricular fibrillation (VF) induction/defibrillation tests at implantation to ensure that the device can reliably sense, detect, and convert VF. The ASSURE Study (Arrhythmia Single Shock Defibrillation Threshold Testing Versus Upper Limit of Vulnerability: Risk Reduc...
Practice guidelines from the American Academy of Neurology for the determination of brain death in adults define brain death as "the irreversible loss of function of the brain, including the brainstem." Neurological determination of brain death is primarily based on clinical examination; if clinical criteria are met, a definitive confirmatory test is indicated. The apnea test remains the gold s...
The investigation involved 25,891 blood donors who attended for the first time the Blood Center of Ribeirão Preto, Brazil, between Jun 23, 1996 and Jun 22, 2001. The objective was to study the proportion of positive serological markers for hepatitis B and C at the initial screening tests and to estimate the prevalence of such infections through the analysis of confirmatory tests, carried out at...
We assessed the reporting times for identification of nasal methicillin-resistant Staphylococcus aureus (MRSA) carriers in 2011 in a university-affiliated hospital using surveillance cultures incubated for 1 and 2 days with ChromID MRSA (bioMérieux, France). Of 2,732 nasal swabs tested, MRSA was detected in 829 (85.6%) and 140 (14.4%) swabs after 1 and 2 days of incubation, respectively, and th...
