Opt-Out Syphilis Screening at an Urgent Care Center in Atlanta: Evaluation of a Pilot Program.

BACKGROUND: Human immunodeficiency virus (HIV) and syphilis disproportionately impact communities with low access to primary care, who often utilize urgent care centers (UCCs) for sexual health care. UCC visits represent an opportunity for identification and treatment of syphilis and linkage to HIV testing and prevention services. We describe a universal, opt-out syphilis screening program pilot at an Atlanta UCC. METHODS: A chart review was performed on patients 18 years and older who were offered opt-out syphilis screening and had a rapid plasma reagin (RPR) test collected from September 1, 2021 to December 31, 2021. Demographic data, syphilis stage and treatment, and HIV testing and serostatus were abstracted from the electronic health record. Patients with reactive RPRs were contacted by a study physician for syphilis staging and treatment, counseling, and referral for HIV preexposure prophylaxis (PrEP) or treatment. RESULTS: From September 1, 2021 to December 31, 2021, 5794 patients were triaged and 1381 underwent RPR screening (23.8%). Eighty (5.8%) had reactive RPRs, and 42 (52.5%) had active syphilis. Of those with active syphilis, 39 (92.9%) received any treatment, and 35 (83.3%) completed treatment. Patients with late syphilis were less likely to complete syphilis treatment (adjusted odds ratio, 0.03; P = 0.009; 95% confidence interval, 0.002-0.42). Among 955 offered PrEP, 41 (4.3%) expressed interest in PrEP, and 7 (0.7%) completed PrEP clinic intake. Univariate analysis did not identify any factors associated with interest in PrEP. CONCLUSIONS: In a UCC setting, routine, opt-out syphilis testing resulted in increased syphilis identification and treatment. It also provided an opportunity for PrEP counseling and referral, although few patients completed PrEP clinic intake.

Mammary tumors alter the fecal bacteriome and permit enteric bacterial translocation.

BACKGROUND: Cancer patients experience gastrointestinal and behavioral symptoms, and are at increased risk of systemic infection and inflammation. These conditions are a major source of morbidity and decreased quality of life prior to cancer treatment, but poorly defined etiologies impede successful treatment. The gastrointestinal microbiota shape inflammation, influence cancer progression and treatment, and colonize tumors. However, research has not directly determined if peripheral tumors influence the microbiome and intestinal physiology, thus influencing gastrointestinal and behavioral symptoms. Therefore, the purpose of this study was to examine consequences of orthotopic, syngeneic mammary tumor implantation, growth, and resection on fecal bacteriome composition and intestinal barrier function in relation to systemic inflammation and enteric bacterial translocation in mice. METHODS: Female mice were randomized to 3 experimental groups: sham surgical control, tumor recipients, and tumor recipients later receiving tumor-resection. Mice were sacrificed three weeks after tumor implantation or resection for collection of stool, colon, spleen, and brain tissue and analysis. RESULTS: Tumor-bearing mice exhibited several markers of colonic barrier disruption, including dampened expression of tight junction proteins (Cldn1 and Ocln) and elevated circulating lipopolysaccharide binding protein (LBP). Compromised colonic barrier integrity was associated with altered fecal bacterial profiles in tumor-mice, including lower relative abundance of Lactobacillus, but higher Bacteroides. Consistent with colonic barrier disruption and altered microbiomes, tumor-mice displayed markers of systemic inflammation including splenomegaly, higher splenic bacterial load, and elevated splenic and brain pro-inflammatory cytokines. Several  bacteria cultured from spleens had 16S rRNA gene amplicons matching those in fecal samples, suggesting they were of intestinal origin. Fecal Lactobacillus was highly-interrelated to physiological parameters disrupted by tumors via correlation network analysis. Tumor resection ameliorated circulating LBP, splenomegaly, and splenic cytokines, but not other parameters associated with loss of colonic barrier integrity and bacterial translocation. CONCLUSIONS: Orthotopic mammary tumors alter the microbiome, reduce intestinal barrier function, increase translocation of enteric bacteria, and alter systemic inflammation. This provides insight into how tumors commence gastrointestinal and behavioral symptoms prior to treatment, and identify targets for future therapeutics, such as probiotic Lactobacillus supplementation.

Bridging the Gap: Evaluation of an Electrocardiogram Curriculum for Advanced Practice Clinicians.

Background: Training programs for advanced practice providers (APP) often have significant variability in their curriculum, including electrocardiogram (ECG) education. Despite limitations in formal ECG training, APPs in the emergency department (ED) may be the first practitioner to interpret an ECG. Foundations of Emergency Medicine (FoEM) offers free, open-access curricula that are widely used for resident education. We sought to improve APP ECG interpretation skills by implementing the FoEM ECG I course. Methods: This was a single-site, pre- and post-intervention study of 23 APPs at our high-acuity, urban ED. In the fall of 2020, APP learners enrolled in a FoEM ECG I course led by faculty and senior resident instructors. The course consisted of six virtual, small-group, active-learning ECG workshops. Participants completed a 15-question multiple-choice test before, immediately after, and six months post-intervention to quantify knowledge acquisition. Additionally, a pre- and post-intervention knowledge, attitudes, and practices survey was administered on ECG interpretation skills and to evaluate the course. We evaluated change in ECG knowledge scores using a Wilcoxon signed-rank test. Changes in self-assessed knowledge were evaluated using an ordinal logistic mixed-effects regression. Results: A total of 23 APPs enrolled in the course. Knowledge assessments showed APPs improved from the pre-test (median 9/15, interquartile range [IQR] 7-11) to the post-test (median 12/15, IQR 10-13; P = 0.001). Test scores did not significantly change from the post-test to the delayed post-test (median 12/15, IQR 12-13; P = 0.30). Respondents' subjective rating of their skill did not significantly change (P = 0.06). Respondents reported no change in their likelihood of approaching an attending when uncertain of the correct interpretation of an ECG (P = 0.16). Overall, 91% were satisfied with the course and 96% agreed that the course difficulty was appropriate. Conclusion: The FoEM ECG course provided a standardized curriculum that improved APP knowledge for interpreting ECGs. Despite this, the course did not alter APPs' willingness to approach physicians for guidance with interpretation of abnormal ECGs. These findings may inform expansion of this concept for other programs who desire formalized APP ECG education.
