Using PCR-based detection and genotyping to trace Streptococcus salivarius meningitis outbreak strain to oral flora of radiology physician assistant.

ABSTRACT: We recently investigated three cases of bacterial meningitis that were reported from a midwestern radiology clinic where facemasks were not worn during spinal injection of contrast agent during myelography procedures. Using pulsed field gel electrophoresis we linked a case strain of S. salivarius to an oral specimen of a radiology physician assistant (RPA). We also used a real-time PCR assay to detect S. salivarius DNA within a culture-negative cerebrospinal fluid (CSF) specimen. Here we extend this investigation through using a nested PCR/sequencing strategy to link the culture-negative CSF specimen to the case strain. We also provide validation of the real-time PCR assay used, demonstrating that it is not solely specific for Streptococcus salivarius, but is also highly sensitive for detection of the closely related oral species Streptococcus vestibularis. Through using multilocus sequence typing and 16S rDNA sequencing we further strengthen the link between the CSF case isolate and the RPA carriage isolate. We also demonstrate that the newly characterized strains from this study are distinct from previously characterized S. salivarius strains associated with carriage and meningitis.

Project description:PurposeAccording to the Williams Institute, 1.4 million U.S. adults identify as transgender. Many experience health care disparities. Professional organizations call for medical education to improve transgender care, but what curricula are being delivered is unknown. The goal of this study was to conduct the first comprehensive, national survey of transgender health care curricula in physician assistant (PA) education.MethodThe authors sent a questionnaire to program directors (PDs) at all 236 U.S. PA programs in June 2018. They categorized programs as those that currently deliver at least 1 hour of transgender health content and those who do not (Teaching/Not Teaching). They examined differences between Teaching and Not Teaching programs using chi-square tests, and they evaluated comments for themes.ResultsThe response rate was 100%. Of the 236 programs, 202 (85.6%) teach transgender content and 34 (14.4%) do not. According to PDs, most transgender content was delivered in medical interviewing (44.1%) or women's health (31.4%) and the most common transgender health topics included differentiating between sex and gender and between behavior and identity (78.8%), followed by health disparities (77.5%) and barriers to care (75.0%). PDs most commonly cited a lack of time (51.3%) and faculty knowledge (35.6%) as barriers for teaching transgender health topics. Half of the PDs (50.4%) ranked transgender health as very or extremely important. The authors detected statistically significant differences between Teaching and Not Teaching programs based on geographic region (P = .01), perceived importance (P ≤ .001), and presence of knowledgeable faculty (P = .01). Presence of knowledgeable faculty was significantly associated with perceived importance (P = .01).ConclusionsThis is the first comprehensive, nationwide survey of transgender health education in U.S. PA programs. A key finding is that the presence of expert faculty is significantly associated with delivery and perceived importance of transgender health curricula.

Project description:ImportanceThe underrepresentation of Black men in the health care workforce, particularly among physician assistants and associates (PAs), represents a missed opportunity to alleviate shortages of health care professionals and enhance workforce diversity. Increasing the number of Black men in the training pipeline could significantly benefit education, patient care, and overall health outcomes.ObjectiveTo analyze patterns from 2013 to 2021 among Black men applying to and matriculating into PA programs and compare these figures with the age-specific US population of Black men.Design, setting, and participantsThis cohort study assessed deidentified application and matriculation data from the Central Application Service for Physician Assistants (CASPA) for PA training programs in the US, alongside US Census data. CASPA applicants reporting race and gender identities as Black male were included. Data were obtained March 10, 2023, from the 2012-2013 to the 2020-2021 application cycles; data were analyzed from June 2023 to May 2024.ExposuresBlack male applicants and matriculation.Main outcomes and measuresPatterns and proportion of Black male applicants and matriculants to PA programs relative to total rates and expected numbers.ResultsFrom 2013 to 2021, PA programs grew 64.3%, with an increase in applicants from 19 761 to 30 196 and matriculants from 6192 to 11 115. Despite this growth, the representation of Black men among applicants (from 435 to 732) and matriculants (from 73 to 156) remained stagnant, averaging 2.2% and 1.2%, respectively, significantly lower than their 8.7% (3 920 231 individuals aged 20-29 years) representation in the US Census. In 2021, the matriculation rate for Black men (156 of 732 [21.3%]) was notably lower than the matriculation rate for all applicants (11 115 of 30 196 [36.8%]). Based on the expected proportion of Black men in the PA applicant age range, there should have been 2641 applicants (actual: 732) and 972 matriculants (actual: 156) across 308 PA programs in 2021; these numbers indicate that, per program, approximately 9 applicants would have to have been evaluated and 3 matriculated to achieve parity, in contrast to the mean of 2 applicants and 1 matriculant per 2 programs.Conclusions and relevanceIn this cohort study of PA applicants and matriculants, Black men remained substantially underrepresented despite overall growth of PA training programs. The low representation among matriculants was due in part to the low numbers of applicants but also to substantially lower matriculation success. This persistent underrepresentation highlights systemic barriers and underscores the need for targeted interventions to achieve a more representative health care workforce. To achieve equitable admissions, each PA program should aim to evaluate 9 Black male applicants and matriculate 3 Black men annually.
