OBJECTIVE Posttraumatic stress disorder (PTSD) and major depression occur frequently following traumatic exposure, both as separate disorders and concurrently. This raises the question of whether PTSD and depression are separate disorders in the aftermath of trauma or part of a single general traumatic stress construct. This study aimed to explore the(More)
OBJECTIVE Accurate information regarding the psychopathological consequences of surviving traumatic injury is of great importance for effective health service design and planning. Regrettably, existing studies vary dramatically in reported prevalence rates of psychopathology within this population. The aim of this study was to identify the prevalence of(More)
Hepatitis C virus (HCV) is a blood-borne virus that disproportionately affects people who inject drugs (PWIDs). Based on extensive interview and blood test data from a longitudinal study in Melbourne, Australia, we describe an individual-based transmission model for HCV spread amongst PWID. We use this model to simulate the transmission of HCV on an(More)
Genetic diversity and relationships among 63 isolates of Escherichia coli from infants in Finland with septicemia or meningitis were assessed by analyzing electrophoretic variation in 21 enzymes encoded by chromosomal genes. Thirty-nine multilocus genotypes (electrophoretic types) were distinguished, 23 of which formed a closely related, distinctive subset(More)
The genetic structure of populations of Legionella pneumophila was defined by an analysis of electrophoretically demonstrable allelic variation at structural genes encoding 22 enzymes in 292 isolates from clinical and environmental sources. Nineteen of the loci were polymorphic, and 62 distinctive electrophoretic types (ETs), representing multilocus(More)
This study explored the relationship between mild traumatic brain injury (MTBI), amnesia, and posttraumatic stress disorder (PTSD). MTBI status and amnesia for the event were assessed in 307 consecutive admissions to a Level 1 Trauma Center. Amnesia did not always occur concurrently with MTBI: 18% of those with MTBI had full recall and over half had partial(More)
OBJECTIVE This exploratory study identified associations between the number of sexual partners reported by men who have sex with men (MSM) and the structure and composition of their social networks. METHODS A cross sectional survey was conducted of men recruited as key informants, through advertising and chain referral. A face to face interview was(More)
OBJECTIVE To describe individual, social network and encounter specific factors associated with protected anal intercourse (PAI) and unprotected anal intercourse (UAI). METHODS This was a cross sectional survey conducted between April and November 2002. A total of 733 sexual encounters were reported by 202 men recruited from the gay community in(More)
One hundred seventy-seven isolates of serotype b Haemophilus influenzae recovered largely from children with invasive disease in the United States were characterized by the electrophoretic mobilities of 16 metabolic enzymes, the NaDodSO4/PAGE pattern of outer-membrane proteins (OMP), and biotype. Thirty-two distinctive multilocus genotypes (electrophoretic(More)
