TL;DR: Analysis of CA-MRSA isolates from the United States, France, Switzerland, Australia, New Zealand, and Western Samoa indicated distinct genetic backgrounds associated with each geographic origin, although predominantly restricted to the agr3 background.
Abstract: Infections caused by community-acquired (CA)-methicillin-resistant Staphylococcus aureus (MRSA) have been reported worldwide. We assessed whether any common genetic markers existed among 117 CA-MRSA isolates from the United States, France, Switzerland, Australia, New Zealand, and Western Samoa by performing polymerase chain reaction for 24 virulence factors and the methicillinresistance determinant. The genetic background of the strain was analyzed by pulsed-field gel electrophoresis (PFGE) and multi-locus sequence typing (MLST). The CAMRSA strains shared a type IV SCCmec cassette and the Panton-Valentine leukocidin locus, whereas the distribution of the other toxin genes was quite specific to the strains from each continent. PFGE and MLST analysis indicated distinct genetic backgrounds associated with each geographic origin, although predominantly restricted to the agr3 background. Within each continent, the genetic background of CA-MRSA strains did not correspond to that of the hospital-acquired MRSA.

TL;DR: Daily TDF-FTC prophylaxis prevented HIV infection in sexually active heterosexual adults and had a significant decline in bone mineral density, which remains unknown.
Abstract: A B S T R AC T Background Preexposure prophylaxis with antiretroviral agents has been shown to reduce the transmission of human immunodeficiency virus (HIV) among men who have sex with men; however, the efficacy among heterosexuals is uncertain. Methods We randomly assigned HIV-seronegative men and women to receive either tenofovir disoproxil fumarate and emtricitabine (TDF–FTC) or matching placebo once daily. Monthly study visits were scheduled, and participants received a comprehensive package of prevention services, including HIV testing, counseling on adherence to medication, management of sexually transmitted infections, monitoring for adverse events, and individualized counseling on risk reduction; bone mineral density testing was performed semiannually in a subgroup of participants. Results A total of 1219 men and women underwent randomization (45.7% women) and were followed for 1563 person-years (median, 1.1 years; maximum, 3.7 years). Because of low retention and logistic limitations, we concluded the study early and followed enrolled participants through an orderly study closure rather than expanding enrollment. The TDF–FTC group had higher rates of nausea (18.5% vs. 7.1%, P<0.001), vomiting (11.3% vs. 7.1%, P = 0.008), and dizziness (15.1% vs. 11.0%, P = 0.03) than the placebo group, but the rates of serious adverse events were similar (P = 0.90). Participants who received TDF–FTC, as compared with those who received placebo, had a significant decline in bone mineral density. K65R, M184V, and A62V resistance mutations developed in 1 participant in the TDF–FTC group who had had an unrecognized acute HIV infection at enrollment. In a modified intention-to-treat analysis that included the 33 participants who became infected during the study (9 in the TDF–FTC group and 24 in the placebo group; 1.2 and 3.1 infections per 100 personyears, respectively), the efficacy of TDF–FTC was 62.2% (95% confidence interval, 21.5 to 83.4; P = 0.03). Conclusions Daily TDF–FTC prophylaxis prevented HIV infection in sexually active heterosexual adults. The long-term safety of daily TDF–FTC prophylaxis, including the effect on bone mineral density, remains unknown.

TL;DR: Self-management education improves GHb levels at immediate follow-up, and increased contact time increases the effect, suggesting that learned behaviors change over time.
Abstract: Objective To evaluate the efficacy of self-management education on GHb in adults with type 2 diabetes. Research design and methods We searched for English language trials in Medline (1980-1999), Cinahl (1982-1999), and the Educational Resources Information Center database (ERIC) (1980-1999), and we manually searched review articles, journals with highest topic relevance, and reference lists of included articles. Studies were included if they were randomized controlled trials that were published in the English language, tested the effect of self-management education on adults with type 2 diabetes, and reported extractable data on the effect of treatment on GHb. A total of 31 studies of 463 initially identified articles met selection criteria. We computed net change in GHb, stratified by follow-up interval, tested for trial heterogeneity, and calculated pooled effects sizes using random effects models. We examined the effect of baseline GHb, follow-up interval, and intervention characteristics on GHb. Results On average, the intervention decreased GHb by 0.76% (95% CI 0.34-1.18) more than the control group at immediate follow-up; by 0.26% (0.21% increase - 0.73% decrease) at 1-3 months of follow-up; and by 0.26% (0.05-0.48) at > or = 4 months of follow-up. GHb decreased more with additional contact time between participant and educator; a decrease of 1% was noted for every additional 23.6 h (13.3-105.4) of contact. Conclusions Self-management education improves GHb levels at immediate follow-up, and increased contact time increases the effect. The benefit declines 1-3 months after the intervention ceases, however, suggesting that learned behaviors change over time. Further research is needed to develop interventions effective in maintaining long-term glycemic control.

TL;DR: Land-use mix had the strongest association with obesity, and relationships among urban form, walk distance, and time in a car were stronger among white than black cohorts, while relationships among the built environment, travel patterns, and weight may vary across gender and ethnicity.
