Abstract
The purpose of this study was to assess if rates of firearm trauma within Atlanta geospatially clustered with HIV prevalence and new HIV diagnosis rates. We retrospectively reviewed our Atlanta trauma center's registry for patients sustaining a ballistic firearm trauma from 2014 through 2018. Using the patient's zip code of home residence, we determined the rate of firearm trauma for that zip code. We obtained publicly available rates for HIV that corresponded with these select zip codes to perform a geospatial cluster analysis. The cohort was comprised of 1495 patients and represented 35 zip codes in Atlanta. The mean rate of firearm trauma for the 35 zip codes was 171.1 (±296.4) per 100,000 people. Compared to all Atlanta, the 35 zip codes' mean HIV prevalence (1863.9 vs 924.1, p < .0001) and new HIV diagnosis rate (396.9 vs 199.7, p < .0001) were significantly higher. Rates of firearm trauma and HIV prevalence demonstrated significant geospatial clustering (β 0.38, 95% CI 0.22-0.53, p < .0001) as did rates of firearm trauma and new HIV diagnoses (β 0.36, 95% CI 0.18-0.54, p = 0.0002). Our findings provide granular geographic data that could guide targeted HIV screening efforts in communities where our firearm-injured patients live.

Abstract
BACKGROUND Digital epidemiology tries to identify diseases dynamics and spread behaviors using digital traces collected via search engines logs and social media posts. However, the impacts of news on information-seeking behaviors have been remained unknown. METHODS Data employed in this research provided from two sources, (1) Parsijoo search engine query logs of 48 months, and (2) a set of documents of 28 months of Parsijoo's news service. Two classes of topics, i.e. macro-topics and micro-topics were selected to be tracked in query logs and news. Keywords of the macro-topics were automatically generated using web provided resources and exceeded 10k. Keyword set of micro-topics were limited to a numerable list including terms related to diseases and health-related activities. The tests are established in the form of three studies. Study A includes temporal analyses of 7 macro-topics in query logs. Study B considers analyzing seasonality of searching patterns of 9 micro-topics, and Study C assesses the impact of news media coverage on users' health-related information-seeking behaviors. RESULTS Study A showed that the hourly distribution of various macro-topics followed the changes in social activity level. Conversely, the interestingness of macro-topics did not follow the regulation of topic distributions. Among macro-topics, "Pharmacotherapy" has highest interestingness level and wider time-window of popularity. In Study B, seasonality of a limited number of diseases and health-related activities were analyzed. Trends of infectious diseases, such as flu, mumps and chicken pox were seasonal. Due to seasonality of most of diseases covered in national vaccination plans, the trend belonging to "Immunization and Vaccination" was seasonal, as well. Cancer awareness events caused peaks in search trends of "Cancer" and "Screening" micro-topics in specific days of each year that mimic repeated patterns which may mistakenly be identified as seasonality. In study C, we assessed the co-integration and correlation between news and query trends. Our results demonstrated that micro-topics sparsely covered in news media had lowest level of impressiveness and, subsequently, the lowest impact on users' intents. CONCLUSION Our results can reveal public reaction to social events, diseases and prevention procedures. Furthermore, we found that news trends are co-integrated with search queries and are able to reveal health-related events; however, they cannot be used interchangeably. It is recommended that the user-generated contents and news documents are analyzed mutually and interactively.

Abstract
OBJECTIVE Our objective was to determine attitudes and opinions of patients seen in our ID Unit on conducting HIV testing universally. METHODS The survey was conducted in patients between 18 and 65 years without known HIV infection. Requested information about the test was previous embodiment, reasons for rejection, opinion on the universal realization, benefits and/or drawbacks, possible test performance, and availability of results "test negative stigma." RESULTS We surveyed 91 patients (54.9% males). Surprisingly, up to 18.7% of patients mistakenly believed that HIV testing is routinely performed without consent. A great majority (98.9%) felt that universal performance on the test would benefit mainly in early diagnosing and/or preventing transmission. Patients younger than 42 years were significantly more prone to doing the test as a routine procedure. Only 4 (4.4%) patients did not participate because they believed they were "not infected." A vast majority (80.5%) of respondents would prefer to have results within the first 24 hours. In addition, 20.7% would have a problem with confidentiality if HIV serology testing was done. CONCLUSIONS In summary, the vast majority (95.6%) of the surveyed patients had a fair opinion about universal HIV testing. Only 4 patients (4.4%) would not consent to HIV testing (because of low-risk perception). Availability of rapid HIV tests can facilitate fast result delivery, facilitating linkage to care. Considering favorable patients' opinion, recent opt-out screening recommendations, highest HIV prevalence in admitted patients, and cost-effectiveness, studies favor universal HIV testing.

Abstract
OBJECTIVE The heightened risk of persons with serious mental illness to contract and transmit HIV is recognized as a public health problem. Persons with HIV and mental illness may be at risk for poor treatment adherence, development of treatment-resistant virus, and worse outcomes. The objective of this study was to test the effectiveness of a community-based advanced practice nurse (APN) intervention (PATH, Preventing AIDS Through Health) to promote adherence to HIV and psychiatric treatment regimens. METHODS Community-dwelling HIV-positive participants with co-occurring serious mental illnesses (N=238) were recruited from community HIV provider agencies from 2004 to 2008 to participate in the randomized controlled trial. Participants in the intervention group (N=128) were assigned an APN who provided community-based care management at a minimum of one visit per week and coordinated clients' medical and mental health care for one year. Viral load and CD4 cell count were evaluated at baseline and 12 months. RESULTS Longitudinal models for continuous log viral load showed that compared with the control group, the intervention group exhibited a significantly greater reduction in log viral load at 12 months (d=-.361 log 10 copies per milliliter, p<.001). Differences in CD4 counts from baseline to 12 months were not statistically significant. CONCLUSIONS This project demonstrated the effectiveness of community-based APNs in delivering a tailored intervention to improve outcomes of individuals with HIV and co-occurring serious mental illnesses. Persons with these co-occurring conditions can be successfully treated; with appropriate supportive services, their viral loads can be reduced.

Abstract
The Centers for Disease Control and Prevention (CDC) recommends offering HIV testing to persons admitted to emergency departments (EDs). Whether by opt-in or opt-out, many EDs (including our own) have found a seroprevalence of 0.8-1.5% when rapid testing is offered. The true seropositivity rate is unknown. We performed a retrospective chart analysis upon all patients presenting to our ED over a 2-week period in the fall of 2007 who had serum drawn as a part of their emergency care. Demographics and clinical characteristics were linked via de-identified serum, which was sent for HIV testing. Nine hundred fifty nine patients had sera available for rapid HIV testing. One hundred twenty one (13%) samples were reactive via the OraQuick(®) test (OraSure Technologies, Bethlehem, PA), a point of care rapid antibody test. Due to concerns about the appropriateness of sera as substrate for the OraQuick(®) technology, reactive samples were retested via standard enzyme immunoassay (EIA)/Western blot. One hundred twelve analyzable samples were retested-38 were positive and 27 of these were from patients who reported a history of HIV infection. The rate of undiagnosed HIV infection was 1.2% (11/914 potentially analyzable samples). Of all patients with HIV in our ED, 29% of them were presumably unaware of their diagnosis. In conclusion, HIV seroprevalence in our urban ED is high, and a large fraction of the patients appears to be unaware of the infection.

Abstract
The use of rapid human immunodeficiency virus (HIV) antibody tests can help reduce the number of individuals positive for HIV who are unaware of their infection. Although several studies have demonstrated that the sensitivity and specificity of rapid HIV tests are comparable to those of enzyme immunoassays, none have addressed the rapidity with which these tests can yield a result and the reliability of such results. In this study, we investigated the performance of VIKIA(®) HIV1/2 rapid tests regarding early reactive results and the stability of these results after sample addition. The results showed that using HIV-1 or HIV-2 positive samples, a positive result could be observed as early as 1 min after the addition of the sample. The ability of this test to detect early HIV-1 primary infection was also assessed using seroconversion specimens. The results demonstrate the high sensitivity of this test, and its suitability for the identification of seroconversion samples in the context of primary infection with HIV-1.

Abstract
Aim To determine the effects of gender and seasonal variations on the prevalence of bacterial septicaemia among children 5 years and younger, and to identify the bacterial agents responsible for septicaemia and their antibiotic susceptibility profiles. Methods Blood was collected from 1,724 children (967 males and 757 females) aged 1 day to 5 years with clinical signs and symptoms of septicaemia. This study was carried out from 1 January to 31 December 2007 at the University of Benin Teaching Hospital, Benin City, Nigeria. The blood samples were processed to diagnose bacterial septicaemia. Bacterial isolates were identified and susceptibility test was performed using standard techniques. Results An overall prevalence of 22.10% of confirmed bacterial septicaemia was observed in this study. Generally, gender and seasonal variations did not significantly affect the prevalence of bacterial septicaemia, though females (50.57%) during the dry season had significantly (p < 0.001) higher prevalence than their male counterparts (19.91%). Staphylococcus aureus was the predominant bacterial isolate causing septicaemia in both seasons, while Citrobacter freundii was the least frequent. Pseudomonas aeruginosa was not recovered during the dry season. Most isolates were susceptible to gentamicin and cefuroxime, but only 1.44% of Staphylococcus aureus strains were susceptible to ceftriaxone. Conclusion Bacterial septicaemia was observed in 22.1% of children 5 years and younger with clinical signs and symptoms of septicaemia. Seasonal variation did not affect the prevalence. Effect of gender was only noticed in the dry season, where females had a higher prevalence than males. Gentamicin and cefuroxime were the most active antibacterial agents. Rational use of antibiotics is advocated.

Abstract
The inpatient medical service may be an important location to identify undiagnosed hepatitis C virus (HCV) infection. We conducted a cross-sectional HCV prevalence study in consecutive patients aged 18-65 admitted in a three-month period to two urban hospitals' general internal medicine and trauma services. Patient sera were anonymously screened for anti-HCV antibody with an enzyme-linked immunoassay and, when anti-HCV positive (+), for HIV. Health system records were examined for prior HCV testing or diagnosis or an HIV diagnosis then linked anonymously to test results. Multivariate logistic regression was used to examine associations of patient and health care factors with unknown HCV+ status. Of 786 unique patients tested (60.3% of all admitted patients), 62 (7.9%) were HCV+ without a prior HCV+ test or diagnosis while 61 patients (7.8%) tested HCV+ but had prior HCV+ test or diagnosis. Of 62 patients with unknown HCV+, 6 (9.7%) were HIV+ but only 3 had a prior HIV diagnosis; of 61 patients with known HCV+, all 9 (14.8%) HIV+ had been diagnosed. Among the 640 patients with prior unknown HCV status, an HCV+ test was strongly associated with age: 50-65 (adjusted odds ratio [AOR] 5.44, CI 2.20-13.48) and age 36-49 (AOR 4.65, CI 1.91-11.32) versus. 18-35. In this anonymous study, we could not obtain HCV risk factor data but the positive and negative predictive values of HCV testing all inpatients with an unknown HCV status were 99.3% and 99.0%, respectively. In similar urban general medicine and trauma services, broader efforts to test for HCV in inpatients aged 36-65 may be warranted.

Abstract
The convergence of HIV, substance abuse (SA), and mental illness (MI) represents a distinctive challenge to health care providers, policy makers, and researchers. Previous research with the mentally ill and substance-abusing populations has demonstrated high rates of psychiatric and general medical comorbidity. Additionally, persons living with HIV/AIDS have dramatically elevated rates of MI and other physical comorbidities. This pattern of co-occurring conditions has been described as a syndemic. Syndemic health problems occur when linked health problems involving 2 or more afflictions interact synergistically and contribute to the excess burden of disease in a population. Evidence for syndemics arises when health-related problems cluster by person, place, or time. This article describes a research agenda for beginning to understand the complex relations among MI, SA, and HIV and outlines a research agenda for the Social and Behavioral Science Research Network in these areas.

Abstract
OBJECTIVES We sought to determine the prevalence of HIV in both inpatient and outpatient settings in 6 Department of Veterans Affairs (VA) health care sites. METHODS We collected demographic data and data on comorbid conditions and then conducted blinded, anonymous HIV testing. We conducted a multivariate analysis to determine predictors of HIV infection. RESULTS We tested 4500 outpatient blood specimens and 4205 inpatient blood specimens; 326 (3.7%) patients tested positive for HIV. Inpatient HIV prevalence ranged from 1.2% to 6.9%; outpatient HIV prevalence ranged from 0.9% to 8.9%. Having a history of hepatitis B or C infection, a sexually transmitted disease, or pneumonia also predicted HIV infection. The prevalence of previously undocumented HIV infection varied from 0.1% to 2.8% among outpatients and from 0.0% to 1.7% among inpatients. CONCLUSIONS The prevalence of undocumented HIV infection was sufficiently high for routine voluntary screening to be cost effective in each of the 6 sites we evaluated. Many VA health care systems should consider expanded routine voluntary HIV screening.

Abstract
BACKGROUND The Centers for Disease Control and Prevention recommends routinely offering HIV testing to inpatients at hospitals with an HIV seroprevalence rate of greater than 1% or an AIDS diagnosis rate of greater than 1.0 per 1000 discharges. This recommendation has not been widely adopted, perhaps because of one of several barriers: the cost of implementing a counseling and testing program; the logistics of HIV counseling and testing on a hospital ward particularly with respect to privacy; concern about the follow-up of HIV test results necessitating patients to return after discharge; and the cultural mindset of screening as an outpatient modality complicated by the fear of raising the possibility of HIV testing and therefore eliciting a negative reaction from a patient who has not requested it. PURPOSE This article focuses on these barriers and some possible solutions, emphasizing the role of FDA-approved rapid HIV tests, which may decrease follow-up issues for HIV testing programs. It also considers hospitalists, given their frontline status and ability to coordinate the multidisciplinary services and system-wide approach required to implement such a program, as leaders in this area.
