Prevalence and Correlates of Trichomonas vaginalis Infection Using the OSOM Rapid Point-of-Care Test Among Women Attending New York City Sexual Health Clinics, May-July 2016.

Using electronic medical record data and OSOM Trichomonas Rapid Tests, Trichomonas vaginalis prevalence was 9.3% among women attending New York City sexual health clinics in 2016. Positivity was associated with black race (adjusted odds ratios 3.73; 95% confidence interval, 1.9-7.1) and vaginal pH of 4.5 or greater (adjusted odds ratios, 1.9; 95% CI, 1.2-3.3).

Awareness and Acceptability of Pre-exposure HIV Prophylaxis Among Men Who have Sex with Men in Baltimore.

This paper assessed characteristics associated with awareness of and willingness to take pre-exposure prophylaxis (PrEP) among Baltimore men who have sex with men (MSM). We used data from BESURE-MSM3, a venue-based cross-sectional HIV surveillance study conducted among MSM in 2011. Multivariate regression was used to identify characteristics associated with PrEP knowledge and acceptability among 399 participants. Eleven percent had heard of PrEP, 48% would be willing to use PrEP, and none had previously used it. In multivariable analysis, black race and perceived discrimination against those with HIV were significantly associated with decreased awareness, and those who perceived higher HIV discrimination reported higher acceptability of PrEP. Our findings indicate a need for further education about the potential utility of PrEP in addition to other prevention methods among MSM. HIV prevention efforts should address the link between discrimination and potential PrEP use, especially among men of color.

Impact of weekly asymptomatic testing for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) in inpatients at an academic hospital.

We analyzed the impact of a 7-day recurring asymptomatic SARS-CoV-2 testing protocol for all patients hospitalized at a large academic center. Overall, 40 new cases were identified, and 1 of 3 occurred after 14 days of hospitalization. Recurring testing can identify unrecognized infections, especially during periods of elevated community transmission.

Healthcare personnel interactive pathogen exposure response system.

Exposure investigations are labor intensive and vulnerable to recall bias. We developed an algorithm to identify healthcare personnel (HCP) interactions from the electronic health record (EHR), and we evaluated its accuracy against conventional exposure investigations. The EHR algorithm identified every known transmission and used ranking to produce a manageable contact list.

Severe acute respiratory coronavirus virus 2 (SARS-CoV-2) exposure investigations using genomic sequencing among healthcare workers and patients in a large academic center.

Severe acute respiratory coronavirus virus 2 (SARS-CoV-2) transmissions among healthcare workers and hospitalized patients are challenging to confirm. Investigation of infected persons often reveals multiple potential risk factors for viral acquisition. We combined exposure investigation with genomic analysis confirming 2 hospital-based clusters. Prolonged close contact with unmasked, unrecognized infectious, individuals was a common risk.

Response of soluble transferrin receptor and iron-related parameters to iron supplementation in elite, iron-depleted, nonanemic female athletes.

OBJECTIVES: To assess the effect of short-term iron supplementation on soluble transferrin receptor (sTfR) and the soluble transferrin receptor/log ferritin ratio in a group of elite, iron-depleted, nonanemic female athletes and to assess the relationship between soluble transferrin receptor and serum ferritin in a group of elite, iron-depleted female athletes. DESIGN: A prospective, interventional study and an observation at 1 point in time. The primary inclusion criteria for each component of the study was serum ferritin less than 30 ng/mL and hemoglobin greater than 12 g/dL. The exclusion criteria were use of iron supplementation within 1 month of the initial assessment, acute or chronic infectious or inflammatory disease, hematological disorders, and recent musculoskeletal injury. SETTING: The Department of Sports Medicine at the Australian Institute of Sport. SUBJECTS: For the prospective study, 51, and for the observational study, 85 elite, iron-depleted (serum ferritin <30 ng/mL), nonanemic (hemoglobin <12 g/dL for the prospective study only) female athletes. Athletes were participants at the elite level in netball, basketball, gymnastics, rowing, volleyball, track and field, soccer, sailing, and cricket. INTERVENTION: Ingestion of 1 iron tablet (325 mg dried ferrous sulfate, equivalent to 105 mg elemental iron) plus one 500-mg tablet of vitamin C each morning for 60 days. RESULTS: Following supplementation, the following changes were statistically significant. Serum ferritin increased (19.7 to 37.4 ng/mL; P < 0.00005), serum transferrin decreased (3.34 to 3.16 g/L; P = 0.023), sTfR decreased (3.46 to 3.16 mg/L; P = 0.006), and sTfR/log ferritin index decreased (1.34 to 1.00; P < 0.00005). If it is assumed that iron stores are depleted when serum ferritin is less than 12 ng/mL and that sTfR could be expected to be elevated below that level of serum ferritin, the following figures can be calculated for the value of sTfR in relation to absent iron stores: sensitivity, 33%; specificity, 96%; positive predictive value, 50%; and negative predictive value, 92%. CONCLUSIONS: Short-term iron supplementation increases iron stores and leads to reductions in sTfR and the sTfR/log ferritin index in elite female athletes. sTfR is not an accurate predictor of serum ferritin less than 12 ng/mL in this group.
