An Interactive Curriculum to Teach Person-Centered Contraceptive Counseling.

Introduction: Following the Dobbs v. Jackson Women's Health Organization Supreme Court decision, it is increasingly important for all providers to be equipped to counsel on contraceptive options. Current curricula are insufficient for medical students to attain competency in contraceptive counseling. Quality contraceptive counseling requires patient-centered communication skills, which are also critical in many other clinical scenarios. Systematic teaching of patient-centered communication is lacking, both in contraceptive counseling and more broadly. Methods: We developed a person-centered contraceptive counseling curriculum containing a reference guide, 5- to 10-minute interactive online module, and 30-minute formative standardized patient session for clerkship-year medical students. Performance during formative sessions was evaluated using a checklist, with standardized patients and preceptors providing real-time feedback. We used surveys of knowledge, self-perceived skills, and attitudes about patient-centered counseling to compare students who did and did not receive the curriculum. Results: Twenty-seven students received the new curriculum. The reference guide and online module were easily integrated into a clinical rotation without requiring additional time spent by educators. The formative session required more resources to implement but was valuable for students to solidify the communication skills in the new curriculum. Checklist results showed that students demonstrated many of the counseling skills taught in the module. Survey results about the impact of the new curriculum were promising but limited by the small sample size. Discussion: The curriculum successfully introduced patient-centered contraceptive counseling skills and provided a valuable practice opportunity. Other sites could adapt components of this curriculum to enhance education in person-centered contraceptive counseling.

A Scoping Review of Preterm Birth Risk Factors.

Preterm birth is a major cause of neonatal morbidity and mortality, but its etiology and risk factors are poorly understood. We undertook a scoping review to illustrate the breadth of risk factors for preterm birth that have been reported in the literature. We conducted a search in the PubMed database for articles published in the previous 5 years. We determined eligibility for this scoping review by screening titles and abstracts, followed by full-text review. We extracted odds ratios and other measures of association for each identified risk factor in the articles. A total of 2,509 unique articles were identified from the search, of which 314 were eligible for inclusion in our final analyses. We summarized risk factors and their relative impacts in the following categories: Activity, Psychological, Medical History, Toxicology, Genetics, and Vaginal Microbiome. Many risk factors for preterm birth have been reported. It is challenging to synthesize findings given the multitude of isolated risk factors that have been studied, inconsistent definitions of risk factors and outcomes, and use of different covariates in analyses. Novel methods of analyzing large datasets may promote a more comprehensive understanding of the etiology of preterm birth and ability to predict the outcome. KEY POINTS: · Preterm birth is difficult to predict.. · Preterm birth has many diverse risk factors.. · Holistic approaches may yield new insights..

A cross-sectional evaluation of HIV testing practices among women in the rural Dominican Republic.

BACKGROUND: The Dominican Republic (DR) ranks among nations with the highest burden of HIV in the Caribbean. Cultural and gender roles in rural areas of the DR may place women at increased HIV risk. However, little is known about sexual health and HIV testing behaviors among women in the rural DR. METHODS: We conducted a needs assessment among a systematic sample of adult women in a rural DR community in 2016. Demographic and behavioral attributes related to HIV testing, sexual health, and healthcare utilization were evaluated. Poisson regression analysis was used to identify demographics and behaviors associated with having had a previous HIV test. Significance was defined as a p-value < 0.05. RESULTS: Among 105 women evaluated, 77% knew someone with HIV and 73% of women reported that they would be very or extremely likely to take an HIV test if offered. Only 68% reported a previous HIV test, including 47% who were tested over 2 years prior. Barriers to HIV testing included low risk perception (23%), distance or requisite travel (13%), and discomfort being tested (11%). Women who had never been tested for HIV were more likely than those who had been tested to be older (p = 0.03), to have a lower level of education (p = 0.04), and to have never been tested for other sexually transmitted infections (STI; p <  0.01). In the Poisson multiple regression model, the only significant predictor of having had an HIV test was having had an STI test (p = 0.03). CONCLUSIONS: In the rural DR, numerous barriers contribute to low prevalence of HIV testing among women. Most women report willingness to have an HIV test and many engage in routine health care, indicating that this population may benefit from incorporating HIV testing and other sexual health promotion activities into routine medical care.

Harnessing the synthetic capabilities of glycopeptide antibiotic tailoring enzymes: characterization of the UK-68,597 biosynthetic cluster.

In this study, a draft genome sequence of Actinoplanes sp. ATCC 53533 was assembled, and an 81-kb biosynthetic cluster for the unusual sulfated glycopeptide UK-68,597 was identified. Glycopeptide antibiotics are important in the treatment of infections caused by Gram-positive bacteria. Glycopeptides contain heptapeptide backbones that are modified by many tailoring enzymes, including glycosyltransferases, sulfotransferases, methyltransferases, and halogenases, generating extensive chemical and functional diversity. Several tailoring enzymes in the cluster were examined in vitro for their ability to modify glycopeptides, resulting in the synthesis of novel molecules. Tailoring enzymes were also expressed in the producer of the glycopeptide aglycone A47934, generating additional chemical diversity. This work characterizes the biosynthetic program of UK-68,597 and demonstrates the capacity to expand glycopeptide chemical diversity by harnessing the unique chemistry of tailoring enzymes.

PDL241, a novel humanized monoclonal antibody, reveals CD319 as a therapeutic target for rheumatoid arthritis.

INTRODUCTION: Targeting the CD20 antigen has been a successful therapeutic intervention in the treatment of rheumatoid arthritis (RA). However, in some patients with an inadequate response to anti-CD20 therapy, a persistence of CD20- plasmablasts is noted. The strong expression of CD319 on CD20- plasmablast and plasma cell populations in RA synovium led to the investigation of the potential of CD319 as a therapeutic target. METHODS: PDL241, a novel humanized IgG1 monoclonal antibody (mAb) to CD319, was generated and examined for its ability to inhibit immunoglobulin production from plasmablasts and plasma cells generated from peripheral blood mononuclear cells (PBMC) in the presence and absence of RA synovial fibroblasts (RA-SF). The in vivo activity of PDL241 was determined in a human PBMC transfer into NOD scid IL-2 gamma chain knockout (NSG) mouse model. Finally, the ability of PDL241 to ameliorate experimental arthritis was evaluated in a collagen-induced arthritis (CIA) model in rhesus monkeys. RESULTS: PDL241 bound to plasmablasts and plasma cells but not naïve B cells. Consistent with the binding profile, PDL241 inhibited the production of IgM from in vitro PBMC cultures by the depletion of CD319+ plasmablasts and plasma cells but not B cells. The activity of PDL241 was dependent on an intact Fc portion of the IgG1 and mediated predominantly by natural killer cells. Inhibition of IgM production was also observed in the human PBMC transfer to NSG mouse model. Treatment of rhesus monkeys in a CIA model with PDL241 led to a significant inhibition of anti-collagen IgG and IgM antibodies. A beneficial effect on joint related parameters, including bone remodeling, histopathology, and joint swelling was also observed. CONCLUSIONS: The activity of PDL241 in both in vitro and in vivo models highlights the potential of CD319 as a therapeutic target in RA.

The comprehensive antibiotic resistance database.

The field of antibiotic drug discovery and the monitoring of new antibiotic resistance elements have yet to fully exploit the power of the genome revolution. Despite the fact that the first genomes sequenced of free living organisms were those of bacteria, there have been few specialized bioinformatic tools developed to mine the growing amount of genomic data associated with pathogens. In particular, there are few tools to study the genetics and genomics of antibiotic resistance and how it impacts bacterial populations, ecology, and the clinic. We have initiated development of such tools in the form of the Comprehensive Antibiotic Research Database (CARD; http://arpcard.mcmaster.ca). The CARD integrates disparate molecular and sequence data, provides a unique organizing principle in the form of the Antibiotic Resistance Ontology (ARO), and can quickly identify putative antibiotic resistance genes in new unannotated genome sequences. This unique platform provides an informatic tool that bridges antibiotic resistance concerns in health care, agriculture, and the environment.
