Asian People Reached by the Centers for Disease Control and Prevention HIV Testing Program in the United States: HIV Testing, Linkage to HIV Medical Care, and Interview for Partner Services 2014-2020.

The purpose of this analysis is to describe HIV tests and associated outcomes for Asian people reached by the Centers for Disease Control and Prevention (CDC) HIV testing program. We analyzed CDC-funded HIV tests among Asian individuals in the United States, Puerto Rico, and the U.S. Virgin Islands (2014-2020). Of the 415,560 tests, the positivity of new diagnoses was higher among males (0.49%, aPR = 7.64) than females (0.06%), and in the West (0.42%, aPR = 1.15) than in the South (0.25%). In non-health care settings, positivity was highest among men who have sex with men (MSM; 0.87%) and transgender people (0.46%). Linkage to HIV medical care among Asian people was 87.5%, and 70.7% were interviewed for partner services. Our findings suggest that improvements are crucial, particularly for Asian MSM, in linkage to care and interview for partner services.

CDC-Funded HIV Testing and Undiagnosed HIV Infection in Ending the HIV Epidemic in the U.S. Jurisdictions.

BACKGROUND: Approximately 13% of persons with HIV (PWH) are unaware of their status. To help end HIV, it is important to understand the relationship between the rates of HIV testing and undiagnosed HIV infection. SETTING: Ending the HIV in the U.S. (EHE) jurisdictions. METHODS: Using 2021 data from the National HIV Surveillance System and the National HIV Prevention Program Monitoring and Evaluation system, we calculated estimated rates of undiagnosed HIV infections per 100,000 population and rates of CDC-funded HIV tests per 1,000 population. We assessed the association between the two rates using Spearman's rank correlation. We also calculated a rank difference between the two rates for each EHE jurisdiction to help identify jurisdictions with greater unfilled needs for HIV testing. RESULTS: Overall, CDC-funded HIV tests per 1,000 population were positively associated with estimated rate of undiagnosed HIV infection per 100,000 population (rho=0.55, p<0.001). EHE jurisdictions with the greatest magnitude of negative rank differences (i.e., higher undiagnosed HIV infection per 100,000 population and lower CDC-funded HIV tests per 1,000 population) were Prince George's County, MD; Mecklenburg County, NC; Hudson County, NJ; Bronx County, NY, and Hamilton County, OH. CONCLUSIONS: In general, CDC-funded HIV testing is being conducted in jurisdictions with the greatest needs. However, we also found large discrepancies between CDC-funded HIV testing and undiagnosed HIV infection rates for some jurisdictions. These jurisdictions may want to identify barriers to their HIV testing services and expand their programs to ensure that all PWH in their jurisdictions are diagnosed.

Structural Discrimination against and Structural Support for Lesbian, Gay, and Bisexual People as a Predictor of Late HIV Diagnoses among Black Men who Have Sex with Men.

Black men who have sex with men (MSM) have been consistently reported to have the highest estimated HIV incidence and prevalence among MSM. Despite broad theoretical understanding that discrimination is a major social and structural determinant that contributes to disparate HIV outcomes among Black MSM, relatively little extant research has empirically examined structural discrimination against sexual minorities as a predictor of HIV outcomes among this population. The present study therefore examines whether variation in policies that explicitly discriminate against lesbian, gay, and bisexual (LGB) people and variation in policies that explicitly protect LGB people differentially predict metropolitan statistical-area-level variation in late HIV diagnoses among Black MSM over time, from 2008 to 2014. HIV surveillance data on late HIV diagnoses among Black MSM in each of the 95 largest metropolitan statistical areas in the United States, from 2008 to 2014, were used along with data on time-varying state-level policies pertaining to the rights of LGB people. Results from multilevel models found a negative relationship between protective/supportive laws and late HIV diagnoses among Black MSM, and a positive relationship between discriminative laws and late HIV diagnoses among Black MSM. These findings illuminate the potential epidemiological importance of policies pertaining to LGB populations as structural determinants of HIV outcomes among Black MSM. They suggest a need for scrutiny and elimination of discriminatory policies, where such policies are currently in place, and for advocacy for policies that explicitly protect the rights of LGB people where they do not currently exist.

HIV Linkage to Care and Pre-Exposure Prophylaxis Among Persons in Non-Health Care Sites Who Are Tested for HIV for the First Time, United States, 2019.

CONTEXT: The Centers for Disease Control and Prevention recommends that all persons aged 13 to 64 years are tested for human immunodeficiency virus (HIV). However, results from US surveys show that 50% of persons and less had ever tested for HIV. PROGRAM: The Centers for Disease Control and Prevention annually funds 60 health departments to conduct comprehensive HIV prevention and surveillance activities that include HIV testing. IMPLEMENTATION: We selected the 31 health departments with quality data (ie, ≤20% missing or invalid values for variables to verify linkage to HIV medical care and new HIV diagnoses) in 2019. Main outcomes were new HIV diagnoses, linkage, and pre-exposure prophylaxis (PrEP) awareness and referrals. We used SAS 9.4 to conduct descriptive, chi-square, and multivariate regression analyses. Our objectives were to determine outcomes and characteristics of persons in non-health care settings who tested for HIV for the first time. EVALUATION: Compared with persons who previously tested for HIV, persons who tested for the first time were more likely to be aged 13 to 29 years than aged 30 years and older (62.0% [24 295/39 192] vs 42.1% [61 911/147 087], P < .001) and have a higher percentage of new HIV diagnoses (0.6% [242/39 320] vs 0.5% [667/147 475], P < .001). Among persons who tested for the first time, overall percentages of linkage, PrEP awareness, and PrEP referral were 73.4%, 33.3%, and 30.8%, respectively. Compared with referent groups, persons who tested for the first time in the South and had a new HIV diagnosis were less likely to be linked (adjusted prevalence ratio [aPR] = 0.72, 95% confidence interval [CI]: 0.59-0.89); persons who inject drugs were less likely to be aware of PrEP (aPR = 0.84, 95% CI: 0.77-0.91); and persons in the Northeast were less likely to receive PrEP referrals (aPR = 0.28, 95% CI: 0.26-0.31). DISCUSSION: Non-health care sites should consider increasing HIV testing, PrEP awareness, and prompt referrals to PrEP and HIV treatment services for persons who have never previously tested.

HIV Positivity, Linkage to Medical Care, Interview for Partner Services, and Pre-Exposure Prophylaxis Awareness and Referral Among Men Who Have Sex With Men Tested in Non-healthcare Settings in the United States, 2019.

OBJECTIVES: Gay, bisexual, and other men who have sex with men (MSM) are disproportionately affected by HIV. This study reports data on HIV testing program outcomes among MSM tested for HIV in non-healthcare settings in the United States. METHODS: We analyzed Centers for Disease Control and Prevention's National HIV Prevention Program Monitoring and Evaluation data collected in 2019. Descriptive and multivariate robust Poisson regression analyses were conducted to summarize the patterns of HIV testing program outcomes [ie, positivity, linkage to HIV medical care within 30 days of diagnosis, interview for partner services (PS), and pre-exposure prophylaxis (PrEP) awareness and referral] by demographic characteristics, HIV prevalence, and testing site type. RESULTS: A total of 123,251 HIV tests were conducted among MSM; of these, 1773 (1.4%) were newly diagnosed with HIV. Among MSM newly diagnosed with HIV, 75% were linked to HIV medical care and 80% were interviewed for PS. Among MSM who tested HIV-negative, 63% were aware of PrEP and 47% of those who were eligible for PrEP were referred to PrEP providers. Referral or linkage to services varied by demographic characteristics or other factors. CONCLUSIONS: Linkage to HIV medical care and interview for PS among MSM newly diagnosed with HIV in non-healthcare settings were below national or funding program targets. Most MSM with risk factors for HIV infection were not referred to PrEP providers. Expanded efforts to address barriers to equitable access to services may help improve HIV-related outcomes among MSM and contribute to ending the HIV epidemic in the United States.

An innovative three-layer strategy in response to a quartan malaria outbreak among forest goers in Hainan Island, China: a retrospective study.

BACKGROUND: An outbreak of Plasmodium malariae infection among forest goers in Sanya City of Hainan Island, China was reported in 2015. In response to this outbreak, an innovative three-layer strategy (TLS) targeted forest goers was adapted based on the 1-3-7 approach. MAIN TEXT: Key elements of TLS are: (i) The village with five malaria cases and adjacent villages were set as the first layer. All residents including forest goers were taken as the high-risk population (HRP). Active case detection (ACD) by blood smear microscopy and PCR was selected as the primary measure, and passive case detection (PCD) as complementary measure. One case was identified under TLS implementation. (ii) The township with cases (Gaofeng Town) and the nearby towns were chosen as the second layer. Only forest goers were screened by ACD, while PCD as a routine screening method. 7831 blood smears collected by ACD and PCD and tested with negative results. (iii) The city with cases (Sanya City) and others 12 counties/county-level cities were selected as the third layer. Malaria cases were monitored passively. A total of 77,555 blood slides were screened by PCD with zero positive sample. For each layer, the malaria vector mosquitoes were monitored using light traps, cattle-baited/human-bait traps. Anopheles minimus (dominant species), An. sinensis and An. dirus were captured. Vector control measures mainly include insecticide residual spraying and long-lasting insecticide nets. The capacity of clinicians, public health practitioners and laboratory technicians has been improved through training. During 2016‒2018, TLS and chemoprophylaxis were implemented in the same areas. In the first layer, all residents were monitored by ACD, and malaria chemoprophylaxis were distributed, 89.5% of forest goers were using chemoprophylaxis against malaria. The blood smears (3126 by ACD plus 1516 by PCD) were with zero positive results. Chemoprophylaxis and ACD were offered to forest goers once a year, and PCD in residents as a complementary measure in the second and third layer, 77.8% and 95.1% of forest goers received chemoprophylaxis. In each layer, vector surveillance and control of malaria and trainings for medical staff were still in place. CONCLUSIONS: TLS was effective in blocking the outbreak by P. malariae among forest goers in Hainan in malaria elimination stage. However, whether it could prevent the malaria resurgence in the post-elimination phase needs to be further assessed.

HIV Preexposure Prophylaxis Awareness and Referral to Providers Among Hispanic/Latino Persons - United States, 2019.

Hispanic or Latino* (Hispanic) persons are disproportionately affected by HIV in the United States. In 2019, Hispanic persons accounted for 18% of the U.S. population, but for 29% of new diagnoses of HIV infection (1). The Ending the HIV Epidemic in the U.S. (EHE) initiative aims to reduce new HIV infections by 90% by 2030 (2). Preexposure prophylaxis (PrEP), medication taken to prevent acquisition of HIV, is an effective strategy for preventing HIV infection.† To examine PrEP awareness and referral to providers among Hispanic persons, CDC analyzed 2019 National HIV Prevention Program Monitoring and Evaluation HIV testing data. Approximately one quarter (27%) of Hispanic persons tested for HIV at CDC-funded sites (n = 310,954) were aware of PrEP, and 22% of those who received a negative HIV test result and were eligible for referral (111,644) were referred to PrEP providers. PrEP awareness and referrals among Hispanic persons were lower compared with those among non-Hispanic White persons. Among Hispanic persons, significant differences were found in PrEP awareness and referrals by age, gender, race, population group, geographic region, and test setting. HIV testing programs can expand PrEP services for Hispanic persons by implementing culturally and linguistically appropriate strategies that routinize PrEP education and referral, collaborating with health care and other providers, and addressing social and structural barriers.

Trajectories of and disparities in HIV prevalence among Black, White, and Hispanic/Latino High Risk Heterosexuals in 89 U.S. Metropolitan statistical areas, 1992-2013.

PURPOSE: Estimates of HIV prevalence, and how it changes over time, are needed to inform action (e.g., resource allocation) to improve HIV-related public health. However, creating adequate estimates of (diagnosed and undiagnosed) HIV prevalence is challenging due to biases in samples receiving HIV testing and due to difficulties enumerating key risk populations. To our knowledge, estimates of HIV prevalence among high risk heterosexuals in the United States produced for geographic areas smaller than the entire nation have to date been only for single years and/or for single cities (or other single geographic locations). METHODS: The present study addresses these gaps by using multilevel modeling on multiple data series, in combination with previous estimates of HIV prevalence among heterosexuals from the extant literature, to produce annual estimates of HIV prevalence among high risk heterosexuals for each of 89 metropolitan statistical areas, from 1992 to 2013. It also produces estimates for these MSAs and years by racial/ethnic subgroup to allow for an examination of change over time in racial/ethnic disparities in HIV prevalence among high risk heterosexuals. RESULTS: The resulting estimates suggest that HIV prevalence among high risk heterosexuals has decreased steadily, on average, from 1992 to 2013. Examination of these estimates by racial/ ethnic subgroup suggests that this trend is primarily due to decreases among Black and Hispanic/Latino high risk heterosexuals. HIV prevalence among white high risk heterosexuals remained steady over time at around 1% during the study period. Although HIV prevalence among Black and Hispanic/Latino high risk heterosexuals was much higher (approximately 3.5% and 3.3%, respectively) than that among whites in 1992, over time these differences decreased as HIV prevalence decreased over time among these subgroups. By 2013, HIV prevalence among Hispanic/Latino high risk heterosexuals was estimated to be very similar to that among white high risk heterosexuals (approximately 1%), with prevalence among Black high risk heterosexuals still estimated to be almost twice as high. CONCLUSIONS: It is likely that as HIV incidence has decreased among heterosexuals from 1992 to 2013, mortality due to all causes has remained disparately high among racial/ethnic minorities, thereby outpacing new HIV cases. Future research should aim to empirically examine this by comparing changes over time in estimated HIV incidence among heterosexuals to changes over time in mortality and causes of death among HIV-positive heterosexuals, by racial/ethnic subgroup.

The Contribution of HIV Testing Funded by the Centers for Disease Control and Prevention to HIV Diagnoses in the United States, 2010-2017.

Understanding the contribution of CDC-funded testing toward diagnosing HIV informs efforts to end the HIV epidemic. Due to differences in surveillance data and CDC program data, which sometimes rely on self-reported information, the number of new diagnoses cannot be directly compared. CDC recently asked grantees to check surveillance data to inform the identification of new diagnoses from CDC-funded tests. In this analysis, we use this newly available information to estimate the percent of all HIV diagnoses from 2010 to 2017 in the United States that result from CDC-funded tests. Among tests with surveillance information, correlates of correct categorization using self-report only were assessed. Weights were calculated from that analysis and used to estimate the total number of CDC-funded new diagnoses. Estimates are presented overall and by demographics/transmission risk group. We estimate that one third of all HIV diagnoses in the United States from 2010 to 2017 resulted from a CDC-funded test. The percent of diagnoses that resulted from CDC-funded tests was higher among some high-risk groups: 41% among 20-29-year-olds and 39% among blacks/African Americans. When compared to total diagnoses in the United States from 2010 to 2017, a large proportion resulted from CDC-funded tests, particularly among young individuals and blacks/African Americans. CDC's contribution to new HIV diagnoses was previously unknown. CDC-funded testing is an important part of the national effort to diagnose all people with HIV as early as possible after infection.

Brief Report: HIV Testing, Diagnosis of HIV Infection, Linkage to Medical Care, and Interview for Partner Services Among Transgender Persons-United States, 2012-2017.

BACKGROUND: Transgender persons are at high risk for HIV infection. Testing is a key component of the national effort to end the HIV epidemic in the United States. SETTING: Sixty-one local and state health departments and 150 community-based organizations funded by the Centers for Disease Control and Prevention to conduct HIV testing programs. METHODS: We analyzed HIV testing data submitted to the Centers for Disease Control and Prevention by funded health departments and community-based organizations during 2012-2017. Descriptive analysis examined patterns of HIV testing and key outcomes (diagnosis of HIV infection, linkage to HIV medical care, and interview for partner services) among transgender persons. Multivariate robust Poisson regression was used to assess associations between HIV testing outcomes and demographic characteristics, census region, and test setting. RESULTS: A total of 82,818 HIV tests were provided to transgender persons. Of these, 2280 (2.8%) transgender persons were diagnosed with HIV infection; 1556 (1.9%) received a new and 724 (0.9%) a previous diagnosis with HIV infection. The highest percentage of new HIV diagnosis was found among persons tested in correctional settings (4.6%), non-Hispanic Blacks (3.5%) and transgender women (2.4%). Among newly diagnosed persons, 85.0% were linked to HIV medical care ≤90 days after diagnosis and 63.5% were interviewed for partner services. CONCLUSIONS: HIV positivity was high, and the delivery of partner services was low, among transgender persons. HIV testing outcomes among transgender persons varied significantly by demographic characteristics and test setting. HIV prevention programs that are responsive to the needs of transgender persons may address gender-related disparities in HIV testing outcomes.

Trajectories of and disparities in HIV prevalence among Black, white, and Hispanic/Latino men who have sex with men in 86 large U.S. metropolitan statistical areas, 1992-2013.

PURPOSE: The challenges of producing adequate estimates of HIV prevalence among men who have sex with men (MSM) are well known. No one, to our knowledge, has published annual estimates of HIV prevalence among MSM over an extended period and across a wide range of geographic areas. METHODS: This article applies multilevel modeling to data integrated from numerous sources to estimate and validate trajectories of HIV prevalence among MSM from 1992 to 2013 for 86 of the largest metropolitan statistical areas in the United States. RESULTS: Our estimates indicate that HIV prevalence among MSM increased, from an across-metropolitan statistical area mean of 11% in 1992 to 20% in 2013 (S.D. = 3.5%). Our estimates by racial/ethnic subgroups of MSM suggest higher mean HIV prevalence among black and Hispanic/Latino MSM than among white MSM across all years and geographic regions. CONCLUSIONS: The increases found in HIV prevalence among all MSM are likely primarily attributable to decreases in mortality and perhaps also to increasing HIV incidence among racial/ethnic minority MSM. Future research is needed to confirm this. If true, health care initiatives should focus on targeted HIV prevention efforts among racial/ethnic minority MSM and on training providers to address cross-cutting health challenges of increased longevity among HIV-positive MSM.

A passive and inclusive strategy to impute missing values of a composite categorical variable with an application to determine HIV transmission categories.

PURPOSE: Multiple imputation (MI) is a widely acceptable approach to missing data problems in epidemiological studies. Composite variables are often used to summarize information from multiple, correlated items. This study aims to assess and compare different MI methods for handling missing categorical composite variables. METHODS: We investigate the problem in the context of a real application: estimating the prevalence of HIV transmission category, which is a composite variable generated by applying a hierarchical algorithm to a group of binary risk source variables from a national program data set. We use simulation studies to compare and assess the performance of alternative MI strategies. These methods include the active imputation, just another variable, and the passive imputation approaches. RESULTS: Our study suggests that the passive imputation approach performs better than the direct imputation approach and the inclusive and general imputation model (i.e. passive imputation with interactions) performs the best. There is no need to embed the information from the variable-combining algorithm in the passive imputation modeling. CONCLUSION: We recommend practitioners adopting an inclusive and general passive imputation modeling strategy.

Trends over time in HIV prevalence among people who inject drugs in 89 large US metropolitan statistical areas, 1992-2013.

PURPOSE: After years of stable or declining HIV prevalence and declining incidence among people who inject drugs (PWID) in the United States, some rapidly emerging outbreaks have recently occurred in new areas (e.g., Scott County, Indiana). However, to our knowledge, trends over time in HIV prevalence among PWID in US metropolitan statistical areas (MSAs) across all major regions of the country have not been systematically estimated beyond 2002, and the extent to which HIV prevalence may be increasing in other areas is largely unknown. This article estimates HIV prevalence among PWID in 89 of the most populated US MSAs, both overall and by geographic region, using more recent surveillance and HIV testing data. METHODS: We computed MSA-specific annual estimates of HIV prevalence (both diagnosed and undiagnosed infections) among PWID for these 89 MSAs, for 1992-2013, using several data series from the Centers for Disease Control and Prevention's (CDC) National HIV Surveillance System and National HIV Prevention Monitoring and Evaluation data; Holmberg's (1997) estimates of 1992 PWID population size and of HIV prevalence and incidence among PWID; and research estimates from published literature using 1992-2013 data. A mixed effects model, with time nested within MSAs, was used to regress the literature review estimates on all of the other data series. Multiple imputation was used to address missing data. Resulting estimates were validated using previous 1992-2002 estimates of HIV prevalence and data on antiretroviral (ARV) prescription volumes and examined for patterns based on geographic region, numbers of people tested for HIV, and baseline HIV prevalence. RESULTS: Mean (across all MSAs) trends over time suggested decreases through 2002 (from approximately 11.4% in 1992 to 9.2% in 2002), followed by a period of stability, and steep increases after 2010 (to 10.6% in 2013). Validation analyses found a moderate positive correlation between our estimates and ARV prescription volumes (r = 0.45), and a very strong positive correlation (r = 0.94) between our estimates and previous estimates by Tempalski et al. (2009) for 1992-2002 (which used different methods). Analysis by region and baseline prevalence suggested that mean increases in later years were largely driven by MSAs in the Western United States and by MSAs in the Midwest that had low baseline prevalence. Our estimates suggest that prevalence decreased across all years in the Eastern United States. These trends were particularly clear when MSAs with very low numbers of people tested for HIV were removed from analyses to reduce unexplained variability in mean trajectories. CONCLUSIONS: Our estimates suggest a fairly large degree of variation in 1992-2013 trajectories of PWID HIV prevalence among 89 US MSAs, particularly by geographic region. They suggest that public health responses in many MSAs (particularly those with larger HIV prevalence among PWID in the early 1990s) were sufficient to decrease or maintain HIV prevalence over time. However, future research should investigate potential factors driving the estimated increase in prevalence after 2002 MSAs in the West and Midwest. These findings have potentially important implications for program and/or policy decisions, but estimates for MSAs with low HIV testing denominators should be interpreted with caution and verified locally before planning action.

HIV Partner Service Delivery Among Transgender Women - United States, 2013-2017.

Transgender women* in the United States are disproportionately affected by human immunodeficiency virus (HIV) infection because of multiple factors, including stigma related to gender identity, unstable housing, limited employment options, and high-risk behaviors, such as sex work, unprotected receptive anal intercourse, and injection drug use, that tend to increase their vulnerability to becoming infected with HIV (1,2). In a recent meta-analysis of 88 U.S. studies conducted during 2006-2017, the mean estimated laboratory-confirmed prevalence of HIV infection among transgender women was 14.2%, and the mean self-reported prevalence estimate was 21.0% (3). The Ending the HIV Epidemic initiative calls for accelerating the implementation of evidence-based strategies in the right geographic areas targeted to the right persons to end the HIV epidemic in the United States (4). HIV partner services are effective strategies offered by public health workers to persons with a diagnosis of HIV infection (index persons) and their sex or needle-sharing partners (partners), who are notified of potential HIV exposure and offered HIV testing and related services. CDC analyzed HIV partner services data submitted by 61 health departments† during 2013-2017. Among 208,304 index persons, 1,727 (0.8%) were transgender women. Overall, 71.5% of index transgender women were interviewed for partner services, which was lower than that for all index persons combined (81.1%). Among 1,089 transgender women named as partners by index persons, 71.2% were notified of potential HIV exposure, which was lower than that for all partners combined (77.1%). Fewer than half (46.5%) of notified transgender women partners were tested for HIV, and approximately one in five (18.6%) of those who were tested received a new diagnosis of HIV infection, slightly higher than for all partners combined (17.6%). Additional efforts are needed to effectively implement partner services among transgender women and identify those whose infection with HIV is undiagnosed, provide timely prevention and care services, reduce HIV transmission, and contribute to ending the HIV epidemic.

HIV Testing Outcomes Among Blacks or African Americans - 50 Local U.S. Jurisdictions Accounting for the Majority of New HIV Diagnoses and Seven States with Disproportionate Occurrences of HIV in Rural Areas, 2017.

Identifying persons with human immunodeficiency virus (HIV) infection who are unaware of their status and linking them to care are critical steps in achieving viral suppression and reducing the risk for transmitting HIV (1). In 2017, 43% of new diagnoses of HIV infection were among persons who self-identify as blacks or African Americans (blacks) (2), who represent 13% of the U.S. population (3). Fewer blacks, compared with whites, were linked to HIV medical care within 90 days of diagnosis, retained in care, or virally suppressed (4). Ending the HIV Epidemic (EHE) is an initiative intended to reduce new HIV infections by 90% from 2020 to 2030 (5). EHE's Phase 1 is focused on 50 jurisdictions* that accounted for >50% of new diagnoses during 2016-2017 and seven states† with disproportionate HIV prevalence in rural areas (5). The purpose of this analysis was to examine HIV testing outcomes among blacks in high prevalence EHE jurisdictions, using CDC's 2017 National HIV Prevention Program Monitoring and Evaluation data. Blacks accounted for 43.2% of CDC-funded tests and 49.1% of new diagnoses of HIV infection. Seventy-nine percent of blacks with newly diagnosed HIV infection were linked to HIV medical care within 90 days (below the 2010 National HIV/AIDS Strategy goal of 85%), 71.4% interviewed for partner services, and 81.8% referred to prevention services. To achieve the goals of EHE, HIV prevention programs should focus on locally tailored evidence-based§ testing strategies to enhance and overcome barriers for linkage to and retention in care and reduce onward HIV transmission and HIV-related disparities.

Kidney Injury Molecule-1 Is Upregulated in Renal Lipotoxicity and Mediates Palmitate-Induced Tubular Cell Injury and Inflammatory Response.

Diabetic nephropathy is increasingly recognized as a major contributor to kidney failure in patients with obesity and type 2 diabetes. This study was designed to identify the molecular mediators of kidney injury associated with metabolic syndrome with or without hyperglycemia. We compared renal gene expression profiles in Zucker lean (ZL), Zucker obese (ZO), and Zucker diabetic (ZD) rats using cDNA microarray with quantitative verification of selected transcripts by real-time PCR. Compared to the 20-week-old ZL control (glucose: 110 ± 8 mg/dL), both prediabetic ZO (glucose: 157 ± 11 mg/dL) and diabetic ZD (glucose: 481 ± 37 mg/dL) rats displayed hyperlipidemia and kidney injury with a high degree of proteinuria. cDNA microarray identified 25 inflammation and injury-related transcriptomes whose expression levels were similarly increased in ZO and ZD kidneys. Among them, kidney injury molecule-1 (KIM-1) was found to be the most highly upregulated in both ZO and ZD kidneys. Immunofluorescence staining of kidney sections revealed a strong correlation between lipid overload and KIM-1 upregulation in proximal tubules of ZO and ZD rats. In cultured primary renal tubular epithelial cells (TECs), administration of saturated fatty acid palmitate resulted in an upregulation of KIM-1, osteopontin, and CD44, which was greatly attenuated by U0126, an inhibitor of extracellular signal-regulated kinase (ERK)1/2. Moreover, knockdown of KIM-1 by siRNA interference inhibited palmitate-induced cleaved caspase-3, osteopontin, and CD44 proteins in primary TECs. Our results indicate that KIM-1 expression is upregulated in renal lipotoxicity and may play an important role in fatty acid-induced inflammation and tubular cell damage in obesity and diabetic kidney disease.

HIV Testing, Positivity, and Receipt of Services among Black, White, and Hispanic Women Participating in HIV Prevention Programs Funded by the Centers for Disease Control and Prevention, 2015.

BACKGROUND: Black women who are positive for human immunodeficiency virus (HIV) are more likely than other HIV-positive women to experience poor health outcomes. Given these disparities, we compared receipt of HIV testing and other preventive services among Black, White, and Hispanic women participating in HIV prevention programs funded by the Centers for Disease Control and Prevention in 2015. METHODS: Data came from 61 health department jurisdictions and 123 community-based organizations. Using Wald χ2 tests, we assessed racial/ethnic differences in HIV testing by demographic characteristics, risk factors, HIV status, HIV service delivery, and (using unlinked data) participation in evidence-based HIV prevention interventions among women. We also assessed temporal changes in Black women's receipt of preventive services (2012-2015). RESULTS: In 2015, there were 1,326,589 HIV testing events (single sessions in which one or more HIV tests are performed to determine HIV status) that occurred among Black, White, and Hispanic women, resulting in 4,868 positive diagnoses. Proportionally fewer Black (vs. White and Hispanic) women were linked to HIV medical care within 90 days (64.4% vs. 69.1% and 73.7%), interviewed for partner services (50.4% vs. 54.4% and 63.5%), and referred to risk reduction services (55.5% vs. 57.7% and 59.8%). From 2012 to 2015, HIV testing events among Black women decreased by 15.2%, but linkage to care within 90 days increased by 30.6% and participation in one or more evidence-based intervention increased by 46.8% among HIV-positive Black women. CONCLUSIONS: Black HIV-positive women were less likely than White and Hispanic women to receive services that prevent HIV-related morbidity and mortality. Additional programmatic efforts are needed to increase the proportion of HIV-positive Black women who are linked to services to reduce HIV disparities among women.

Previously Diagnosed HIV-Positive Persons: The Role of Centers for Disease Control and Prevention-Funded HIV Testing Programs in Addressing Their Needs.

BACKGROUND: Increased HIV testing efforts have resulted in retesting previously diagnosed persons. This study examined Centers for Disease Control and Prevention (CDC)-funded HIV testing programs to evaluate how the needs of previously diagnosed persons are being addressed. METHODS: The following were examined by demographic and test setting among previously diagnosed HIV-positive persons in 2015: CDC-funded HIV testing, previously diagnosed HIV positivity, current care status, and linkage to care. In addition, trends of HIV positivity and previously diagnosed HIV-positivity were examined from 2011 to 2015. RESULTS: In 2015, CDC funded 3,026,074 HIV tests, and 27,729 were HIV-positive tests. Of those, 13,528 (48.8%) were previously diagnosed persons. Only 11.6% of previously diagnosed persons reported already being in HIV care; after excluding them, 62.1% of previously diagnosed persons were linked within 90 days. In addition, the percentage of previously diagnosed persons steadily increased from 2011 (25.9%) to 2015 (34.1%; P < 0.001). CONCLUSIONS: Almost half of all HIV-positive tests were among previously diagnosed persons, but only 11.6% were already in HIV care. Linkage is necessary among persons who already know their HIV status because they either were never linked or need to be reengaged into care. Barriers in linkage and retention among this group also need to be addressed.

Estimation of the Percentage of Newly Diagnosed HIV-Positive Persons Linked to HIV Medical Care in CDC-Funded HIV Testing Programs.

Missing data create challenges for determining progress made in linking HIV-positive persons to HIV medical care. Statistical methods are not used to address missing program data on linkage. In 2014, 61 health department jurisdictions were funded by Centers for Disease Control and Prevention (CDC) and submitted data on HIV testing, newly diagnosed HIV-positive persons, and linkage to HIV medical care. Missing or unusable data existed in our data set. A new approach using multiple imputation to address missing linkage data was proposed, and results were compared to the current approach that uses data with complete information. There were 12,472 newly diagnosed HIV-positive persons from CDC-funded HIV testing events in 2014. Using multiple imputation, 94.1% (95% confidence interval (CI): [93.7%, 94.6%]) of newly diagnosed persons were referred to HIV medical care, 88.6% (95% CI: [88.0%, 89.1%]) were linked to care within any time frame, and 83.6% (95% CI: [83.0%, 84.3%]) were linked to care within 90 days. Multiple imputation is recommended for addressing missing linkage data in future analyses when the missing percentage is high. The use of multiple imputation for missing values can result in a better understanding of how programs are performing on key HIV testing and HIV service delivery indicators.

HIV Testing, Linkage to HIV Medical Care, and Interviews for Partner Services Among Women - 61 Health Department Jurisdictions, United States, Puerto Rico, and the U.S. Virgin Islands, 2015.

Diagnoses of human immunodeficiency virus (HIV) infection among women declined 17% during 2011-2015, and a total of 7,498 women received a diagnosis of HIV infection in 2015 (1). Although black or African American (black) women accounted for only 12% of the U.S. female population, 60% of women with newly diagnosed HIV infection were black (1,2). By the end of 2014, an estimated 255,900 women were living with HIV infection (3), including approximately 12% who did not know they were infected; in addition, approximately 45% of women who had received a diagnosis had not achieved viral suppression (3). HIV testing is an important public health strategy for identifying women with HIV infection and linking them to HIV medical care. Analysis of CDC-funded program data submitted by 61 health departments in 2015 indicated that among 4,749 women tested who received a diagnosis of HIV infection, 2,951 (62%) had received a diagnosis in the past (previous diagnosis), and 1,798 (38%) were receiving a diagnosis for the first time (new diagnosis). Of those who had received a previous diagnosis, 87% were not in HIV medical care at the time of the current test. Testing and identifying women who are living with HIV infection but who are not in care (regardless of when they received their first diagnosis) and rapidly linking them to care so they can receive antiretroviral therapy and become virally suppressed are essential for reducing HIV infection among all women.
