Objectives. We assessed whether multiple psychosocial factors are additive in their relationship to sexual risk behavior and self-reported HIV status (i.e., can be characterized as a syndemic) among young transgender women and the relationship of indicators of social marginalization to psychosocial factors. Methods. Participants (n = 151) were aged 15 to 24 years and lived in Chicago or Los Angeles. We collected data on psychosocial factors (low self-esteem, polysubstance use, victimization related to transgender identity, and intimate partner violence) and social marginalization indicators (history of commercial sex work, homelessness, and incarceration) through an interviewer-administered survey. Results. Syndemic factors were positively and additively related to sexual risk behavior and self-reported HIV infection. In addition, our syndemic index was significantly related to 2 indicators of social marginalization: a history of sex work and previous incarceration. Conclusions. These findings provide evidence for a syndemic of co-occurring psychosocial and health problems in young transgender women, taking place in a context of social marginalization.

Efavirenz, a potent inhibitor of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase, is a promising addition to the antiretroviral armamentarium. Efavirenz levels and HIV-1 RNA levels were measured in cerebrospinal fluid (CSF) and plasma of 10 HIV-1-infected patients taking efavirenz, 600 mg daily, in combination with other antiretroviral medications. Efavirenz was detected in the CSF at a mean concentration of 35.1 nM (range, 6. 6-58.9 nM), which was above the IC95 for wild-type HIV-1. The mean CSF-to-plasma ratio was 0.61% (range, 0.26%-0.99%). CSF HIV-1 RNA levels were ascertained in 9 of the patients; all were <400 copies/mL after a mean of 26 weeks on therapy. Eight of the 9 patients had no detectable virus in plasma. These results indicate that efavirenz is present in the CSF at low levels and is effective in suppressing CSF viral levels when used in combination therapy.

Waldorf schools had exceptionally high average PBE rates, and Montessori and holistic schools had higher annual increases in PBE rates. Children in these schools may be at higher risk for spreading vaccine-preventable diseases if trends are not reversed.

BACKGROUND It is not known whether reductions in socioeconomic and racial disparities in incidence of invasive pneumococcal disease (defined as the isolation of Streptococcus pneumoniae from a normally sterile body site) noted after pneumococcal conjugate vaccine introduction have been sustained. METHODS Individual-level data collected from twenty Tennessee counties participating in Active Bacterial Core surveillance over 19 years were linked to neighborhood-level socioeconomic factors. Incidence rates were analyzed across three periods, pre-PCV7 (1998–1999), pre-PCV13 (2001–2009) and post-PCV13 (2011–2016) by socioeconomic factors. RESULTS 8,491 cases of invasive pneumococcal disease were identified. Incidence for invasive pneumococcal disease decreased from 22.9 (1998–1999) to 17.9 (2001–2009) to 12.7 (2011–2016) cases per 100,000-person years. Post-PCV13 incidence of PCV13-serotype disease in high and low poverty neighborhoods were 3.1 (95% CI: 2.7-3.5) and 1.4 (1.0-1.8) respectively, compared with pre-PCV7 incidence of 17.8 (15.7-19.9) and 6.4 (4.9-7.9). Before PCV introduction, incidence of PCV13-serotype disease was higher in blacks than whites (black: 17.3 [15.10-19.50]; white: 11.8 [10.6-13.0]); after introduction, PCV13-type disease incidence was greatly reduced in both groups (white: 2.7 [2.4-3.0]; black: 2.2 [1.8-2.6]).

Objectives: Between 2003 and 2013, the rate of neonatal abstinence syndrome (NAS)—a postnatal drug withdrawal syndrome—in Tennessee increased approximately 10-fold. NAS surveillance is relatively new, and underestimation associated with surveillance has not been described. We compared data from the Tennessee NAS public health surveillance system (TNSS) with a second source of NAS data, hospital discharge data system (HDDS), and estimated the true number of infants with NAS using capture-recapture methods. Methods: We obtained NAS data on cases of NAS among Tennessee infants from TNSS and HDDS from January 1, 2013, through December 31, 2016. We matched cases of NAS identified in TNSS to cases identified in HDDS. We estimated the true number of infants with NAS by using the Lincoln-Peterson estimator capture-recapture methodology. Results: During the study period, 4070 infants with NAS were reported to TNSS, and 5321 infants with NAS were identified in HDDS; 2757 were in both data sets. Using capture-recapture methods, the total estimated number of infants with NAS during the study period was 7855 (annual mean = 1972; estimated range = 1531-2427), which was 93% more than in TNSS and 48% more than in HDDS. Drugs used for the medication-assisted treatment of substance use disorder were the most commonly reported substances associated with NAS (n = 2389, 59%). Conclusions: TNSS underestimated the total burden of NAS based on the capture-recapture estimate. Case-based public health surveillance is important for monitoring the burden of and risk factors for NAS and helping guide public health interventions.

Background Injection drug use (IDU) is an established but uncommon risk factor for candidemia. Surveillance for candidemia is conducted in East Tennessee, an area heavily impacted by the opioid crisis and IDU. We evaluated IDU-associated candidemia to characterize the epidemiology and estimate the burden. Methods We assessed the proportion of candidemia cases related to IDU during January 1, 2014–September 30, 2018, estimated candidemia incidence in the overall population and among persons who inject drugs (PWID), and reviewed medical records to compare clinical features and outcomes among IDU-associated and non-IDU candidemia cases. Results The proportion of IDU-associated candidemia cases in East Tennessee increased from 6.1% in 2014 to 14.5% in 2018. Overall candidemia incidence in East Tennessee was 13.5/100 000, and incidence among PWID was 402–1895/100 000. Injection drug use-associated cases were younger (median age, 34.5 vs 60 years) and more frequently had endocarditis (39% vs 3%). All-cause 30-day mortality was 8% among IDU-associated cases versus 25% among non-IDU cases. Conclusions A growing proportion of candidemia in East Tennessee is associated with IDU, posing an additional burden from the opioid crisis. The lower mortality among IDU-associated cases likely reflects in part the younger demographic; however, Candida endocarditis seen among approximately 40% underscores the seriousness of the infection and need for prevention.
