Correlates of sexual assault in a sample of male African American crack cocaine users

Although numerous studies have reported an association between substance use and sexual assault, little is known about the impact of sexual assault on male African American crack cocaine users. This study found that from a sample of 137 respondents from Houston, Texas, one-third reported having been sexually assaulted at least once during their lifetime. Respondents who reported sexual assault were using cocaine more often and were more likely to be physically dependent on drugs and to report greater numbers of physical health problems due to their drug use. However, no differences were identified in respect of reported mental health problems, or problems with family, friends or the workplace associated with drug use. The findings suggest further research as to the impact of sexual assault on male crack cocaine users is warranted and that clinical staff working with male substance users require some awareness of the impacts of sexual assault.

Complete genome sequence of Rhizobium leguminosarum bv trifolii strain WSM2304, an effective microsymbiont of the South American clover Trifolium polymorphum

Rhizobium leguminosarum bv. trifolii is the effective nitrogen fixing microsymbiont of a diverse range of annual and perennial Trifolium (clover) species. Strain WSM2304 is an aerobic, motile, non-spore forming, Gram-negative rod isolated from Trifolium polymorphum in Uruguay in 1998. This microsymbiont predominated in the perennial grasslands of Glencoe Research Station, in Uruguay, to competitively nodulate its host, and fix atmospheric nitrogen. Here we describe the basic features of WSM2304, together with the complete genome sequence, and annotation. This is the first completed genome sequence for a nitrogen fixing microsymbiont of a clover species from the American centre of origin. We reveal that its genome size is 6,872,702 bp encoding 6,643 protein-coding genes and 62 RNA only encoding genes. This multipartite genome was found to contain 5 distinct replicons; a chromosome of size 4,537,948 bp and four circular plasmids of size 4,537,948, 1,266,105, 501,946, 308,747 and 257,956 bp.

Cross-cultural examination of the structure of the Revised American Pain Society Patient Outcome Questionnaire (APS-POQ-R)

This study investigated the cross-cultural factor stability and internal consistency of the Revised American Pain Society Patient Outcome Questionnaire (APS-POQ-R); a measure of the quality of postoperative pain management employed internationally. We conducted exploratory factor analysis (EFA) of APS-POQ-R data from two point-prevalence studies comprising 268 and 311 surveys of Danish and Australian medical-surgical patients. Parallel analysis indicated four and three factor solutions for Danish and Australian patients respectively, which accounted for 58.1% and 52.9% of variance. Internal consistency was unsatisfactory among both Danish (Cronbach α=.54) and Australian (Cronbach α=.63) cohorts. There was a high degree of between-group similarity in item-factor loadings of variables coded as "pain experience", but not "pain management". This reflected cross-cultural differences in ratings of treatment satisfaction. For Danish patients, satisfaction was associated with the degree of pain severity and activity interference whereas for Australian patients, satisfaction was associated with their perceived ability to participate in treatment. To facilitate further cross-cultural comparison, we compared our findings to past research conducted in the U.S. and Iceland. EFA supported the construct validity of the APS-POQ-R as a measure of "pain experience", but indicated that items measuring "pain management" may vary cross-culturally. Findings highlighted the need for further validation of the APS-POQ-R internationally. PERSPECTIVE: This study revealed the APS-POQ-R as a valid measure of postoperative pain experience for Danish and Australian patients. Measures of patients' perception of pain management were not robust to group differences in treatment expectations and demonstrated cross-cultural instability. Results highlighted difficulties in establishing stable cross-cultural, cross-population subscales for the APS-POQ-R.

Evaluation of Satisfaction of Patients Rehabilitated With Zygomatic Fixtures

Purpose: The aim of this study was to evaluate the satisfaction of patients rehabilitated with zygomatic fixtures and prosthesis with immediate loading.Materials and Methods: The study selected patients who were rehabilitated with zygomatic implants at the clinic of the Latin American Institute for Dental Research and Education (ILAPEO. Curitiba-PR. Brasil) between 2005 and 2009. The patients were asked to answer a control-questionnaire during their follow-up visits. Data were collected regarding the level of patient satisfaction, reason for dissatisfaction, number of post-operative clinical sessions, and the type of complication. Sixteen patients were selected: 10 females and 6 males.Results: Half of the patients were completely satisfied while the other half were satisfied with some complaints. The complaints were related to hygiene, esthetics, phonetics, and discomfort during chewing. Regarding the post-operative evaluation, 50% of the patients were attended due to the prosthesis (62.5%) and the implant (37.5%).Conclusions: The treatment with zygomatic fixtures is predictable and reliable. The patients were satisfied both with implants and prosthesis. (C) 2012 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 70: 314-319, 2012

Reproductive pattern of the South American endemic shrimp Artemesia longinaris (Decapoda : Penaeoidea), off São Paulo State, Brazil

Sexual maturity, temporal reproductive pattern, and recruitment of juveniles were examined for the penaeoid shrimp Artemesia longinaris sampled for five and a half years in a tropical locality off the coast of São Paulo (23 degrees S), Brazil. Monthly samples were taken from January 1998 to June 2003 at depths between 5 and 45 m. Ovarian maturity was used to examine breeding in adult females. Recruitment was defined as the percentage of juveniles of the total number of individuals in each month and season. A total of 10 288 females and 5 551 males were collected. Estimated sizes (carapace length) at the onset of sexual maturity were 11.0 mm and 13.4 mm for males and females, respectively. Over the five and a half years, females with ripe gonads were found in every season, with the highest percentages in summer (January-March). Juvenile shrimps occur-red year-round. These results suggest a continuous reproduction of A. longinaris with temperature acting as an environmental stimulus for the duration of the ovary development cycle. These data and the hypothesis of the intrusion of the South Atlantic Central Water mass, which lowered water temperature and raised plankton production, suggest that the end of spring and the beginning of summer were the principal reproductive months. The classical paradigm of continuous reproduction at lower latitudes, with increased seasonality of breeding period at higher latitudes seems to apply to this species.
