This study aimed to evaluate virulence factors and genetic markers of antimicrobial resistance in 400 Staphylococcus aureus strains isolated from bovine mastitis in four Brazilian states, as well as to assess the association between these characteristics and field information. Virulence factors and drug resistance genes were identified by PCR screening. Biofilm-forming and hemolytic phenotype were detected using Congo red Tryptic Soy Broth and defibrinated sheep blood agar, respectively. Of all isolates, 83.5% were biofilm-forming and 98.5% strains exhibited biofilm gene icaAD, and a significant association between phenotype and genotype for biofilm was observed (P = 0.0005). Hemolysin genes were observed in 82.85% (hla+hlb+), 16.5% (hla+) and 0.75% (hlb+) isolates, whereas the hemolytic phenotype exhibited was complete and incomplete hemolysis in 64.25%, complete in 28.25%, incomplete in 4.75%, and negative in 2.75% of the strains. Virulence factors genes luk, seb, sec, sed, and tst were observed in 3.5%, 0. that confer resistance to almost all classes of antimicrobial agents approved for use in animals and humans were found. Overall, the data point to a great pathogenic potential of S. aureus associated with bovine mastitis and to the non-negligible risks to public health of staphylococcal infections from animal origin.

Intraoperative margin assessment can reduce positive margins in patients undergoing breast-conserving surgery. However, reports on intraoperative margin assessment have described only the use of either imprint cytology or frozen section. This study was designed to elucidate the effect of intraoperative margin assessment using imprint cytology followed by frozen section.

Overall, 522 patients were enrolled. First, the entire surgical margin was subjected to imprint cytology. Frozen section was performed only in cases with "positive" or "suspicious" imprint cytology results. An additional intraoperative excision was performed in patients with frozen section-positive lesion sites. All margins were evaluated using postoperative permanent sections after excision.

Among 522 patients, 136 (26.1%) were imprint cytology-positive, and 386 (73.9%) were imprint cytology-negative. Among the 386 imprint cytology-negative patients not subjected to frozen section, 11 (2.1%) were permanent sections-positive (imprint cytt can overcome the limitations of cytology and histology performed individually.

To analyze municipal- and individual-level factors related to the prevalence of teenage pregnancy in Colombia during 2015.

We analyzed 660,767 births registers, of which 21.5% recorded adolescent women. At an individual level, marital status, educational level, area of residence, and access to health services were included in the analysis. At the contextual level, Colombian municipal socioeconomic characteristics and proxies of violence and poverty were analyzed. A multilevel logistic regression model was generated with a Markov Chain Monte Carlo estimation method using 100,000 simulations in MLwiN 2.32 software.

Multilevel modeling revealed an increased risk of teenage pregnancy in municipalities with the highest numbers of people expelled by forced displacement (OR 1.21; CI 95%, 1.13-1.29) and with unsatisfied basic needs (OR 1.09; CI 95%, 1.02-1.17). At an individual level, the majority of the teenage women were unmarried and/or had an unstable partnership, a low level of educational, a subsidized health regimen, and resided in the municipal seat.

Municipal contextual variables related to poverty, violence, and social inequity contribute to an increase in teenage pregnancy in Colombia. At the individual level, marital status, educational level, and area of residence is associated with teenage pregnancy. It is therefore imperative to include municipal contextual characteristics in the design of the national political agenda.

A life-course perspective emphasizes healthy behaviors before, during, and after pregnancy to support a multi-generational risk reduction in obesity for mothers and infants. Optimal timing, content, and dose of such interventions is not well defined.

We conducted a nested cohort within a randomized trial to evaluate whether a healthy lifestyle intervention around pregnancy led to a "spill-over effect," including a healthier rate (kg/week) of maternal gestational weight gain, and infant growth during the first year. Study enrollment began in 2012, follow-up data collection completed in 2018, and the data were analyzed in 2019. The intervention focused on healthy maternal diet and physical activity but not pregnancy weight or infant feeding. Outcome data were abstracted from electronic medical records.

Of the 165 women who became pregnant, 114 enrolled in the nested cohort. The average pre-pregnancy BMI was 29.6 (SD 5.1) kg/m

. Mixed effects models suggested clinically insignificant differences in both the rate of gestational weight gain (-0.02 kg/week; 95% CI -0.09, 0.06) and the rate of infant growth (difference at 1 year -0.002 kg/cm; 95% CI -0.009, 0.005).

A behavioral intervention that focused on overall maternal health delivered in the time around pregnancy did not result in a "spill-over effect" on healthy gestational weight gain or healthy infant growth during the first year of life.

To validate the Dutch version of AOSpine PROST (Patient Reported Outcome Spine Trauma).

Patients were recruited from two level-1 trauma centers from the Netherlands. Next to the AOSpine PROST, patients also filled out SF-36 for concurrent validity. Descriptive statistics were used to analyze the characteristics. check details Content validity was assessed by evaluating the number of inapplicable or missing questions. Also floor and ceiling effects were analyzed. Internal consistency was assessed by calculating Cronbach's α and item-total correlation coefficients (itcc). Spearman correlation tests were performed within AOSpine PROST items and in correlation with SF-36. Test-retest reliability was analyzed using Intraclass Correlation Coefficients (ICC). Responsiveness was assessed by calculating effect sizes (ES) and standardized response mean (SRM). Factor analysis was performed to explore any dimensions within AOSpine PROST.

Out of 179 enrolled patients, 163 (91.1%) were included. Good results were obtained for content validity.
