RESUMEN

ABSTRACT: This study, completed at an sexually transmitted infection (STI) clinic in 2019 to 2020, evaluated patient preferences for telemedicine, express, and standard visits. Active PrEP users preferred telemedicine and express visits, patients with prior STIs preferred express visits, and cisgender women preferred standard visits. Configuring STI clinic visit types requires shared decision making and individualization.

RESUMEN

BACKGROUND AND AIMS: Coronavirus disease 2019 (COVID-19) has been associated with acute liver injury (ALI) manifested by increased liver enzymes in reports worldwide. Prevalence of liver injury and associated clinical characteristics are not well defined. We aim to identify the prevalence of and risk factors for development of COVID-19-associated ALI in a large cohort in the United States. APPROACH AND RESULTS: In this retrospective cohort study, all patients who underwent SARS-CoV-2 testing at three hospitals in the NewYork-Presbyterian network were assessed. Of 3,381 patients, 2,273 tested positive and had higher initial and peak alanine aminotransferase (ALT) than those who tested negative. ALI was categorized as mild if ALT was greater than the upper limit of normal (ULN) but <2 times ULN, moderate if ALT was between 2 and 5 times the ULN, and severe if ALT was >5 times the ULN. Among patients who tested positive, 45% had mild, 21% moderate, and 6.4% severe liver injury (SLI). In multivariable analysis, severe ALI was significantly associated with elevated inflammatory markers, including ferritin (odds ratio [OR], 2.40; P < 0.001) and interleukin-6 (OR, 1.45; P = 0.009). Patients with SLI had a more severe clinical course, including higher rates of intensive care unit admission (69%), intubation (65%), renal replacement therapy (RRT; 33%), and mortality (42%). In multivariable analysis, peak ALT was significantly associated with death or discharge to hospice (OR, 1.14; P = 0.044), controlling for age, body mass index, diabetes, hypertension, intubation, and RRT. CONCLUSIONS: ALI is common in patients who test positive for SARS-CoV-2, but is most often mild. However, among the 6.4% of patients with SLI, a severe disease course should be anticipated.

RESUMEN

BACKGROUND: Ending the HIV epidemic requires linkage of at-risk individuals from diverse health care settings to comprehensive HIV prevention services. Sexually transmitted infections (STIs) are significant biomarkers of HIV risk and should trigger preexposure prophylaxis (PrEP) discussion. We reviewed STI testing practices outside of sexual health clinics to identify opportunities for improvement in the provision of HIV prevention services. METHODS: An electronic sexual health dashboard was used to identify patient encounters with a positive gonorrhea, chlamydia, and/or rapid plasma reagin test result between January 1, 2019, and August 23, 2019, at a large urban academic medical center. A retrospective chart review was performed to assess HIV testing, completeness of STI screening, and HIV prevention discussion; inadequate screening was defined as no HIV test in 12 months before STI diagnosis. RESULTS: A total of 815 patients with 856 patient encounters were included. Patients were predominantly female (64.4%); median age was 24 years (range, 18-85 years). The most common test and most common positive test result was the genitourinary gonorrhea/chlamydia nucleic acid amplification test. Multisite testing was rare (7.5% of patient encounters) and performed more frequently in men than in women (20.3% vs. 0.36%). Women were also more likely to be inadequately screened for HIV (15.1% vs. 25.8%).Documentation of PrEP discussion was rare (4.7% of patient encounters) compared with safe sex (44.6%) and condoms (49.8%). Preexposure prophylaxis was discussed almost exclusively with men compared with women (17% vs. 1.1%). CONCLUSIONS: In patients diagnosed with bacterial STI outside of sexual health clinics, gaps in HIV prevention exist. HIV screening, multisite STI screening, and discussion of PrEP were particularly infrequent among women.

RESUMEN

Context: Populations severely affected by COVID-19 are also at risk for vitamin D deficiency. Common risk factors include older age, chronic illness, obesity, and non-Caucasian race. Vitamin D deficiency has been associated with risk for respiratory infections and failure, susceptibility and response to therapy for enveloped virus infection, and immune-mediated inflammatory reaction.Objective: To test the hypothesis that 25-hydroxyvitamin D[25(OH)D] deficiency is a risk factor for severity of COVID-19 respiratory and inflammatory complications.Design: We examined the relationship between prehospitalization 25(OH)D levels (obtained 1-365 days prior to admission) and COVID-19 clinical outcomes in 700 COVID-19 positive hospitalized patients.Primary Outcomes: Discharge status, mortality, length of stay, intubation status, renal replacement.Secondary Outcomes: Inflammatory markers.Results: 25(OH)D levels were available in 93 patients [25(OH)D:25(IQR:17-33)ng/mL]. Compared to those without 25(OH)D levels, those with measurements did not differ in age, BMI or distribution of sex and race, but were more likely to have comorbidities. Those with 25(OH)D < 20 ng/mL (n = 35) did not differ from those with 25(OH)D ≥ 20 ng/mL in terms of age, sex, race, BMI, or comorbidities. Low 25(OH)D tended to be associated with younger age and lower frequency of preexisting pulmonary disease. There were no significant between-group differences in any outcome. Results were similar in those ≥50 years, in male/female-only cohorts, and when differing 25(OH)D thresholds were used (<15 ng/mL and <30 ng/mL). There was no relationship between 25(OH)D as a continuous variable and any outcome, even after controlling for age and pulmonary disease.Conclusions: These preliminary data do not support a relationship between prehospitalization vitamin D status and COVID-19 clinical outcomes.

RESUMEN

UNLABELLED: Animal development and physiology depend on beneficial interactions with microbial symbionts. In many cases, the microbial symbionts are horizontally transmitted among hosts, thereby making the acquisition of these microbes from the environment an important event within the life history of each host. The light organ symbiosis established between the Hawaiian squid Euprymna scolopes and the bioluminescent bacterium Vibrio fischeri is a model system for examining how hosts acquire horizontally transmitted microbial symbionts. Recent studies have revealed that the light organ of wild-caught E. scolopes squid contains polyclonal populations of V. fischeri bacteria; however, the function and development of such strain diversity in the symbiosis are unknown. Here, we report our phenotypic and phylogenetic characterizations of FQ-A001, which is a V. fischeri strain isolated directly from the light organ of an E. scolopes individual. Relative to the type strain ES114, FQ-A001 exhibits similar growth in rich medium but displays increased bioluminescence and decreased motility in soft agar. FQ-A001 outcompetes ES114 in colonizing the crypt spaces of the light organs. Remarkably, we find that animals cocolonized with FQ-A001 and ES114 harbor singly colonized crypts, in contrast to the cocolonized crypts observed from competition experiments involving single genotypes. The results with our two-strain system suggest that strain diversity within the squid light organ is a consequence of diversity in the single-strain colonization of individual crypt spaces. IMPORTANCE: The developmental programs and overall physiologies of most animals depend on diverse microbial symbionts that are acquired from the environment. However, the basic principles underlying how microbes colonize their hosts remain poorly understood. Here, we report our findings of bacterial strain competition within the coevolved animal-microbe symbiosis composed of the Hawaiian squid and bioluminescent bacterium Vibrio fischeri Using fluorescent proteins to differentially label two distinct V. fischeri strains, we find that the strains are unable to coexist in the same niche within the host. Our results suggest that strain competition for distinct colonization sites dictates the strain diversity associated with the host. Our study provides a platform for studying how strain diversity develops within a host.

RESUMEN

Pre-exposure prophylaxis (PrEP) prevents HIV, but low rates of retention in care limit its effectiveness. We conducted a prospective survey-based study to investigate reasons for PrEP disengagement among men who have sex with men attending a sexual health clinic at a large urban academic medical center in New York City who were lost to follow up; surveys asked about current PrEP status, reasons for disengagement, attitudes toward PrEP, substance use, sexual practices, and behavioral/social determinants of health. Outreach attempts were made to 634 patients; majority of eligible participants were unable to be contacted (59%). Among those who agreed to participate (n = 175), 21% asked to re-establish care. Among those who completed the questionnaire (n = 86), 36% were taking PrEP. The most common reasons for PrEP discontinuation were cost/lack of insurance coverage (31%), decreased HIV risk perception (29%), and side effects (16%). Among those with decreased perception of risk, 62% were less sexually active, 38% were no longer engaging in anal sex, and 31% were using condoms for prevention. Participants reported that free medication (60%), having a sexual partner recommend PrEP (13%), and being able to receive PrEP from a primary care provider (13%) would encourage restarting PrEP. Findings were limited by low response rate (12% of eligible subjects completed the survey) and lack of Spanish-language questionnaires. Understanding reasons for loss-to-PrEP follow-up is essential for HIV prevention. Many people lost to follow up still desired PrEP, underscoring the importance of outreach, benefits navigators, and expansion of PrEP into primary care settings.

RESUMEN

INTRODUCTION: Youth aged 13-29 years represent 23% of the population but account for 40% of new HIV diagnoses, with risk peaking at ages 22-23 years. We assessed sexual behaviors, PrEP knowledge and attitudes among patients of 6 School-Based-Health-Centers (SBHCs) located in Northern Manhattan and the Bronx. METHOD: 667 patients, aged 13-19 years, completed a survey in the SBHCs waiting rooms between 10/2018 - 4/2019 RESULTS: Of the survey respondents attending SBHCs, 32% reported ever having heard of PrEP and, upon learning of PrEP, 67% stated that would be very likely (35%) or somewhat likely (32%) to take PrEP if it was offered to them free of charge. DISCUSSION: Youth of color are disproportionately infected by HIV throughout the US. Efforts are needed to educate adolescents on the benefits of PrEP, SBHCs are well situated to reduce barriers in providing PrEP directly to those who would benefit from its protection..

RESUMEN

HIV pre-exposure prophylaxis (PrEP) effectively reduces new HIV diagnoses. High rates of incident bacterial sexually transmitted infections (STIs) have been observed in patients eligible for and adherent to PrEP. Observational studies generally report low long-term retention in PrEP care. Limited data exist on the rates of bacterial STI diagnosis upon re-engagement with PrEP services. We conducted a retrospective chart review within the HIV prevention program of an urban academic medical center in New York City. Eligible patients started PrEP from 2015 to 2019, then resumed PrEP services after a gap in care of at least 180 days. Demographic, clinical, and laboratory data were used to characterize the patient population and rates of bacterial STI diagnosis at re-engagement. In total, 286 patients were identified, with 316 qualifying re-engagement visits. Twenty-nine percent of patients had continued PrEP during the care gap, and 30% reported discontinuing medication due to a perceived change in risk. A new STI was diagnosed at 19% of re-engagement visits. There was no statistically significant difference in rates of new STI between individuals returning on or off PrEP, nor between those with perceived lower risk and those without. Individuals who fall out of PrEP services and subsequently re-engage remain at high risk of bacterial STI during the gap in care, regardless of whether PrEP medication is continued or the patient perceives themselves to be at lower HIV acquisition risk. Providers should strongly encourage patients discontinuing PrEP to remain engaged in sexual health services. Alternatives to clinic-based PrEP care must still include regular bacterial STI screening.

RESUMEN

BACKGROUND: The progression of clinical manifestations in patients with coronavirus disease 2019 (COVID-19) highlights the need to account for symptom duration at the time of hospital presentation in decision-making algorithms. METHODS: We performed a nested case-control analysis of 4103 adult patients with COVID-19 and at least 28 days of follow-up who presented to a New York City medical center. Multivariable logistic regression and classification and regression tree (CART) analysis were used to identify predictors of poor outcome. RESULTS: Patients presenting to the hospital earlier in their disease course were older, had more comorbidities, and a greater proportion decompensated (<4 days, 41%; 4-8 days, 31%; >8 days, 26%). The first recorded oxygen delivery method was the most important predictor of decompensation overall in CART analysis. In patients with symptoms for <4, 4-8, and >8 days, requiring at least non-rebreather, age ≥ 63 years, and neutrophil/lymphocyte ratio ≥ 5.1; requiring at least non-rebreather, IL-6 ≥ 24.7 pg/mL, and D-dimer ≥ 2.4 µg/mL; and IL-6 ≥ 64.3 pg/mL, requiring non-rebreather, and CRP ≥ 152.5 mg/mL in predictive models were independently associated with poor outcome, respectively. CONCLUSION: Symptom duration in tandem with initial clinical and laboratory markers can be used to identify patients with COVID-19 at increased risk for poor outcomes.

RESUMEN

Importance: Critical illness, a marked inflammatory response, and viruses such as SARS-CoV-2 may prolong corrected QT interval (QTc). Objective: To evaluate baseline QTc interval on 12-lead electrocardiograms (ECGs) and ensuing changes among patients with and without COVID-19. Design, Setting, and Participants: This cohort study included 3050 patients aged 18 years and older who underwent SARS-CoV-2 testing and had ECGs at Columbia University Irving Medical Center from March 1 through May 1, 2020. Patients were analyzed by treatment group over 5 days, as follows: hydroxychloroquine with azithromycin, hydroxychloroquine alone, azithromycin alone, and neither hydroxychloroquine nor azithromycin. ECGs were manually analyzed by electrophysiologists masked to COVID-19 status. Multivariable modeling evaluated clinical associations with QTc prolongation from baseline. Exposures: COVID-19, hydroxychloroquine, azithromycin. Main Outcomes and Measures: Mean QTc prolongation, percentage of patients with QTc of 500 milliseconds or greater. Results: A total of 965 patients had more than 2 ECGs and were included in the study, with 561 (58.1%) men, 198 (26.2%) Black patients, and 191 (19.8%) aged 80 years and older. There were 733 patients (76.0%) with COVID-19 and 232 patients (24.0%) without COVID-19. COVID-19 infection was associated with significant mean QTc prolongation from baseline by both 5-day and 2-day multivariable models (5-day, patients with COVID-19: 20.81 [95% CI, 15.29 to 26.33] milliseconds; P < .001; patients without COVID-19: -2.01 [95% CI, -17.31 to 21.32] milliseconds; P = .93; 2-day, patients with COVID-19: 17.40 [95% CI, 12.65 to 22.16] milliseconds; P < .001; patients without COVID-19: 0.11 [95% CI, -12.60 to 12.81] milliseconds; P = .99). COVID-19 infection was independently associated with a modeled mean 27.32 (95% CI, 4.63-43.21) millisecond increase in QTc at 5 days compared with COVID-19-negative status (mean QTc, with COVID-19: 450.45 [95% CI, 441.6 to 459.3] milliseconds; without COVID-19: 423.13 [95% CI, 403.25 to 443.01] milliseconds; P = .01). More patients with COVID-19 not receiving hydroxychloroquine and azithromycin had QTc of 500 milliseconds or greater compared with patients without COVID-19 (34 of 136 [25.0%] vs 17 of 158 [10.8%], P = .002). Multivariable analysis revealed that age 80 years and older compared with those younger than 50 years (mean difference in QTc, 11.91 [SE, 4.69; 95% CI, 2.73 to 21.09]; P = .01), severe chronic kidney disease compared with no chronic kidney disease (mean difference in QTc, 12.20 [SE, 5.26; 95% CI, 1.89 to 22.51; P = .02]), elevated high-sensitivity troponin levels (mean difference in QTc, 5.05 [SE, 1.19; 95% CI, 2.72 to 7.38]; P < .001), and elevated lactate dehydrogenase levels (mean difference in QTc, 5.31 [SE, 2.68; 95% CI, 0.06 to 10.57]; P = .04) were associated with QTc prolongation. Torsades de pointes occurred in 1 patient (0.1%) with COVID-19. Conclusions and Relevance: In this cohort study, COVID-19 infection was independently associated with significant mean QTc prolongation at days 5 and 2 of hospitalization compared with day 0. More patients with COVID-19 had QTc of 500 milliseconds or greater compared with patients without COVID-19.
