Sexual Health among Female Refugee Youth: An Ecological Approach

Refugee youth face several sexual health challenges, and research investigating contributing factors has primarily focused on identifying contextual barriers. However, it is also important to investigate protective factors, as well as how both risk and protective factors work together across contexts. The present study explored facilitators and barriers to refugee youth sexual health and how they combine to predict behavior using thematic text analysis and narrative analysis of twelve in-depth interviews with female refugees ages 18-24. Findings revealed four primary themes: sex/relationship restrictions, judgment/disapproval, support, and youth reactions. The first three factors were present across multiple ecological levels, such as parents, peers, and culture. Furthermore, these contextual factors were related to one another, such that youth who violate sociocultural sex/relationship restrictions experience actual or anticipated judgment from others, which leads to fear, embarrassment, and risky sexual behavior. These findings have important implications for sexual health education interventions with refugee youth

First Complete Genome Sequence of Corynebacterium riegelii.

Here, we report the first complete genome sequence of Corynebacterium riegelii strain PUDD_83A45, isolated from the urine of a patient with urinary tract infection. The genome measured 2.56 Mb and contained no plasmid

Gradient-based algorithm for determining tumor volumes in small animals using planar fluorescence imaging platform

Planar fluorescence imaging is widely used in biological research because of its simplicity, use of nonionizing radiation, and high-throughput data acquisition. In cancer research, where small animal models are used to study the in vivo effects of cancer therapeutics, the output of interest is often the tumor volume. Unfortunately, inaccuracies in determining tumor volume from surface-weighted projection fluorescence images undermine the data, and alternative physical or conventional tomographic approaches are prone to error or are tedious for most laboratories. Here, we report a method that uses a priori knowledge of a tumor xenograft model, a tumor-targeting near infrared probe, and a custom-developed image analysis planar view tumor volume algorithm (PV-TVA) to estimate tumor volume from planar fluorescence images. Our algorithm processes images obtained using near infrared light for improving imaging depth in tissue in comparison with light in the visible spectrum. We benchmarked our results against the actual tumor volume obtained from a standard water volume displacement method. Compared with a caliper-based method that has an average deviation from an actual volume of 18% (204.34 ± 115.35 mm(3)), our PV-TVA average deviation from the actual volume was 9% (97.24 ± 70.45 mm(3); P < .001). Using a normalization-based analysis, we found that bioluminescence imaging and PV-TVA average deviations from actual volume were 36% and 10%, respectively. The improved accuracy of tumor volume assessment from planar fluorescence images, rapid data analysis, and the ease of archiving images for subsequent retrieval and analysis potentially lend our PV-TVA method to diverse cancer imaging applications

The Tibetan Uterotonic Zhi Byed 11: Mechanisms of Action, Efficacy, and Historical Use for Postpartum Hemorrhage

Objective. To explore evidence for the traditional Tibetan medicine, Zhi Byed 11 (ZB11), for use as a uterotonic. Methods. The eleven ingredients in ZB11 were chemically analyzed by mass spectroscopy. A review was conducted of Western allopathic literature for scientific studies on ZB11's individual components. Literature from Tibetan and other traditional paradigms were reviewed. Results. Potential mechanisms of action for ZB11 as a uterotonic include laxative effects, a dose-dependant increase in smooth muscle tissue peristalsis that may also affect the uterus smooth muscle, and chemical components that are prostaglandin precursors and/or increase prostaglandin synthesis. A recent RCT demonstrated comparable efficacy to misoprostol in reducing severe postpartum hemorrhage (PPH) (>1000 mL) and greater effect than placebo. Historical and anecdotal evidence for ZB11 and its ingredients for childbirth provide further support. Discussion. ZB11 and its ingredients are candidates for potentially effective uterotonics, especially in low-resource settings. Further research is warranted to understand the mechanisms of action and synergy between ingredients

Preparing Postbaccalaureates for Entry and Success in Biomedical PhD Programs

Certain racial and ethnic groups, individuals with disabilities, and those from low socioeconomic backgrounds remain underrepresented (UR) in the biomedical sciences. This underrepresentation becomes more extreme at each higher education stage. To support UR scholars during the critical transition from baccalaureate to PhD, we established an intensive, 1-yr postbaccalaureate training program. We hypothesized that this intervention would strengthen each participant’s competitiveness for leading PhD programs and build a foundation of skills and self-efficacy important for success during and after graduate school. Scholar critical analysis skills, lab technique knowledge, and Graduate Record Examination scores all improved significantly during the program. Scholars reported significant confidence growth in 21 of 24 categories related to success in research careers. In 5 yr, 91% (41/45) of scholars transitioned directly into PhD programs. Importantly, 40% (18/45) of participating postbaccalaureate scholars had previously been declined acceptance into graduate school; however, 17/18 of these scholars directly entered competitive PhD programs following our training program. Alumni reported they were “extremely well” prepared for graduate school, and 95% (39/41) are currently making progress to graduation with a PhD. In conclusion, we report a model for postbaccalaureate training that could be replicated to increase participation and success among UR scholars in the biomedical sciences

Penicillin Use in Meningococcal Disease Management: Active Bacterial Core Surveillance Sites, 2009.

In 2009, in the Active Bacterial Core surveillance sites, penicillin was not commonly used to treat meningococcal disease. This is likely because of inconsistent availability of antimicrobial susceptibility testing and ease of use of third-generation cephalosporins. Consideration of current practices may inform future meningococcal disease management guidelines

Whole-Genome Sequencing and Concordance Between Antimicrobial Susceptibility Genotypes and Phenotypes of Bacterial Isolates Associated with Bovine Respiratory Disease.

Extended laboratory culture and antimicrobial susceptibility testing timelines hinder rapid species identification and susceptibility profiling of bacterial pathogens associated with bovine respiratory disease, the most prevalent cause of cattle mortality in the United States. Whole-genome sequencing offers a culture-independent alternative to current bacterial identification methods, but requires a library of bacterial reference genomes for comparison. To contribute new bacterial genome assemblies and evaluate genetic diversity and variation in antimicrobial resistance genotypes, whole-genome sequencing was performed on bovine respiratory disease-associated bacterial isolates (Histophilus somni, Mycoplasma bovis, Mannheimia haemolytica, and Pasteurella multocida) from dairy and beef cattle. One hundred genomically distinct assemblies were added to the NCBI database, doubling the available genomic sequences for these four species. Computer-based methods identified 11 predicted antimicrobial resistance genes in three species, with none being detected in M. bovis While computer-based analysis can identify antibiotic resistance genes within whole-genome sequences (genotype), it may not predict the actual antimicrobial resistance observed in a living organism (phenotype). Antimicrobial susceptibility testing on 64 H. somni, M. haemolytica, and P. multocida isolates had an overall concordance rate between genotype and phenotypic resistance to the associated class of antimicrobials of 72.7% (P &lt; 0.001), showing substantial discordance. Concordance rates varied greatly among different antimicrobial, antibiotic resistance gene, and bacterial species combinations. This suggests that antimicrobial susceptibility phenotypes are needed to complement genomically predicted antibiotic resistance gene genotypes to better understand how the presence of antibiotic resistance genes within a given bacterial species could potentially impact optimal bovine respiratory disease treatment and morbidity/mortality outcomes
