Impact of AIDS Education and Training Centers on the US HIV Medical Workforce.

OBJECTIVES: To examine the extent to which the AIDS Education and Training Centers (AETCs) are increasing the number and racial/ethnic diversity of HIV medical providers, in accordance with the US National HIV/AIDS Strategy (NHAS). METHODS: We used administrative data from funding year 2012-2013 to describe AETC trainee characteristics, including the types of medical providers trained, compared with national estimates of available US medical providers to estimate the proportion of providers trained for every 1000 available providers by professional group and race/ethnicity. RESULTS: AETCs trained 56 127 unique trainees, of whom 64.1% were medical providers and 45.5% were racial/ethnic minorities. Compared to national proportions, participation in AETC training was higher among racial/ethnic minorities. The proportions of racial/ethnic minority groups trained differed across regional AETCs. CONCLUSIONS: AETCs support NHAS goals by expanding the HIV medical workforce and strengthening the skills of minority medical providers to deliver high quality HIV care. Public Health Implications. Some AETCs made greater contributions to training different types of racial/ethnic minorities, which indicates varied approaches are needed to best target these efforts in communities heavily impacted by HIV.

The Association Between Neighborhood Poverty and HIV Diagnoses Among Males and Females in New York City, 2010-2011.

OBJECTIVE: We assessed the association of neighborhood poverty with HIV diagnosis rates for males and females in New York City. METHODS: We calculated annual HIV diagnosis rates by ZIP Code, sex, and neighborhood poverty level using 2010-2011 New York City (NYC) HIV surveillance data and data from the U.S. Census 2010 and American Community Survey 2007-2011. Neighborhood poverty levels were percentage of residents in a ZIP Code with incomes below the federal poverty threshold, categorized as 0%-<10% (low poverty), 10%-<20% (medium poverty), 20%-<30% (high poverty), and 30%-100% (very high poverty). We used sex-stratified negative binomial regression models to measure the association between neighborhood-level poverty and HIV diagnosis rates, controlling for neighborhood-level education, race/ethnicity, age, and percentage of men who have sex with men. RESULTS: In 2010-2011, 6,184 people were newly diagnosed with HIV. Median diagnosis rates per 100,000 population increased by neighborhood poverty level overall (13.7, 34.3, 50.6, and 75.6 for low-, medium-, high-, and very high-poverty ZIP Codes, respectively), for males, and for females. In regression models, higher neighborhood poverty remained associated with higher diagnosis rates among males (adjusted rate ratio [ARR] = 1.63, 95% confidence interval [CI] 1.34, 1.97) and females (ARR=2.14, 95% CI 1.46, 3.14) for very high- vs. low-poverty ZIP Codes. CONCLUSION: Living in very high- vs. low-poverty urban neighborhoods was associated with increased HIV diagnosis rates. After controlling for other factors, the association between poverty and diagnosis rates was stronger among females than among males. Alleviating poverty may help decrease HIV-related disparities.

Acceptability of home self-tests for HIV in New York City, 2006.

Data from a 2006 telephone survey representative of New York City adults showed that more than half (56.2%) of those aged 18 to 64 years responded favorably to a question about acceptability of a rapid home HIV test. More than two thirds of certain subpopulations at high risk for HIV reported that they would use a rapid home HIV test, but approximately half who expressed interest had indications of financial hardship. The match of acceptability and HIV risk bodes well for self-testing utility, but cost might impede uptake.

Elevated risk for invasive meningococcal disease among persons with HIV.

BACKGROUND: An association between HIV and invasive meningococcal disease (IMD) has been suggested by several previous studies but has not been fully described in the era of highly active antiretroviral therapy in the United States. OBJECTIVE: To estimate the risk for IMD and death in people living with HIV/AIDS (PLWHA) in New York City (NYC) and the contribution of CD4(+) cell count and viral load (VL) to IMD risk. DESIGN: Comparison of the incidence rate of IMD among PLWHA with that among HIV-uninfected persons. Surveillance data on IMD for patients aged 15 to 64 years from 2000 to 2011 were matched to death and HIV registries to calculate IMD risk and case-fatality ratios. A subset of PLWHA who had a CD4(+) cell count and VL measurement near the time of their IMD infection was included in age-matched case-control analyses to assess HIV markers and IMD risk. SETTING: Retrospective cohort from communicable disease surveillance. PATIENTS: 265 persons aged 15 to 64 years with IMD during 2000 to 2011. MEASUREMENTS: Meningococcal and HIV data abstracted from surveillance and registry databases, including CD4(+) cell counts and VL. RESULTS: The average annual incidence rate of IMD was 0.39 cases per 100 000 persons. The relative risk for IMD among PLWHA in NYC during 2000 to 2011 was 10.0 (95% CI, 7.2 to 14.1). Among PLWHA, patients with IMD were 5.3 times (CI, 1.4 to 20.4 times) as likely as age-matched control patients to have CD4(+) counts less than 0.200 × 10(9) cells/L. LIMITATION: Missing data on smoking status and comorbidity. CONCLUSION: People living with HIV/AIDS in NYC are at increased risk for IMD. Cost-effectiveness and vaccine efficacy studies are needed to evaluate the value of a national recommendation for routine meningococcal vaccination of PLWHA.

Novel use of surveillance data to detect HIV-infected persons with sustained high viral load and durable virologic suppression in New York City.

BACKGROUND: Monitoring of the uptake and efficacy of ART in a population often relies on cross-sectional data, providing limited information that could be used to design specific targeted intervention programs. Using repeated measures of viral load (VL) surveillance data, we aimed to estimate and characterize the proportion of persons living with HIV/AIDS (PLWHA) in New York City (NYC) with sustained high VL (SHVL) and durably suppressed VL (DSVL). METHODS/PRINCIPAL FINDINGS: Retrospective cohort study of all persons reported to the NYC HIV Surveillance Registry who were alive and ≥12 years old by the end of 2005 and who had ≥2 VL tests in 2006 and 2007. SHVL and DSVL were defined as PLWHA with 2 consecutive VLs ≥100,000 copies/mL and PLWHA with all VLs ≤400 copies/mL, respectively. Logistic regression models using generalized estimating equations were used to model the association between SHVL and covariates. There were 56,836 PLWHA, of whom 7% had SHVL and 38% had DSVL. Compared to those without SHVL, persons with SHVL were more likely to be younger, black and have injection drug use (IDU) risk. PLWHA with SHVL were more likely to die by 2007 and be younger by nearly ten years, on average. CONCLUSIONS/SIGNIFICANCE: Nearly 60% of PLWHA in 2005 had multiple VLs, of whom almost 40% had DSVL, suggesting successful ART uptake. A small proportion had SHVL, representing groups known to have suboptimal engagement in care. This group should be targeted for additional outreach to reduce morbidity and secondary transmission. Measures based on longitudinal analyses of surveillance data in conjunction with cross-sectional measures such as community viral load represent more precise and powerful tools for monitoring ART effectiveness and potential impact on disease transmission than cross-sectional measures alone.

Barriers to HIV testing among HIV/AIDS concurrently diagnosed persons in New York City.

OBJECTIVES: To assess barriers to human immunodeficiency virus (HIV) testing, health care contacts history, and HIV testing history among patients diagnosed concurrently with HIV and acquired immunodeficiency syndrome (AIDS). METHODS: We surveyed patients concurrently diagnosed with HIV/AIDS who had participated in the partner notification program of the New York City Department of Health and Mental Hygiene, between January 2008 and December 2008. RESULTS: The most common reason interviewees volunteered for delaying testing (64%) was that they did not believe they were at risk for HIV. When read a list of potential barriers, 69% of interviewees replied affirmatively that they did not test for HIV because they did not believe they were at risk, and 52% replied affirmatively that they did not test because they thought their behaviors kept them safe from getting HIV. Half of all interviewees reported having insurance during part or all of the year before they were diagnosed with HIV/AIDS, and 70% had at least 1 health care visit in the year before they were diagnosed with HIV/AIDS. CONCLUSIONS: A lack of perception of risk was the most common reason for not testing for HIV sooner among these concurrently diagnosed patients. The majority of these patients were accessing medical care, indicating that this population could have benefited from routine HIV testing.

Impact of accelerated progression to AIDS on public health monitoring of late HIV diagnosis.

Some patients develop AIDS within a year of HIV infection ("accelerated progression"). Classifying such cases as late HIV diagnosis may lead to inaccurate evaluation of HIV testing efforts. We sought to determine this group's contribution to overall late diagnosis rates. To identify cases of accelerated progression (development of AIDS within 12 months of a negative HIV test), we reviewed published HIV seroconverter cohort studies and used New York City's (NYC) HIV/AIDS surveillance registry. From the literature review, three seroconverter cohort studies revealed that 1.0-3.6% of participants had accelerated progression to AIDS. Applying this frequency estimate to the number of new infections in NYC (4762) for 2006 calculated by the Centers for Diseases Control and Prevention's incidence formula, we estimated that 3.6-13.0% of 1317 NYC HIV cases who are diagnosed with AIDS within 12 months of HIV diagnosis are accelerated progressors, not persons HIV infected for many years who did not test and present with AIDS (i.e., delayed diagnosis). In addition, our analysis of the 2006 NYC surveillance registry confirmed the occurrence of accelerated progression in a population-based setting; 67 accelerated progressors were reported and 9 (13%) could be confirmed through follow-up medical record review. With increased HIV testing initiatives, the irreducible proportion of AIDS cases with accelerated progression must be considered when interpreting late diagnosis data.

Ovarian function and cigarette smoking.

Cigarette smoking has been implicated in reproductive outcomes including delayed conception, but mechanisms underlying these associations remain unclear. One potential mechanism is the effect of cigarette smoking on reproductive hormones; however, studies evaluating associations between smoking and hormone levels are complicated by variability of hormones and timing of specimen collection. We evaluated smoking among women participating in the BioCycle Study, a longitudinal study of menstrual cycle function in healthy, premenopausal, regularly menstruating women (n = 259). Fertility monitors were used to help guide timing of specimen collection. Serum levels of oestradiol, progesterone, follicle-stimulating hormone (FSH), luteinising hormone (LH) and total sex-hormone binding globulin (SHBG) across phases of the menstrual cycle were compared between smokers and non-smokers. We observed statistically significant phase-specific differences in hormone levels between smokers and non-smokers. Compared with non-smokers, smokers had higher levels of FSH in the early follicular phase and higher LH at menses after adjusting for potential confounding factors of age, race, body mass index, parity, vigorous exercise, and alcohol and caffeine intake through inverse probability of treatment weights. No statistically significant differences were observed for oestradiol, progesterone or SHBG. These phase-specific differences in levels of LH and FSH in healthy, regularly menstruating women who are current smokers compared with non-smokers reflect one mechanism by which smoking may influence fertility and reproductive health.
