BackgroundInfections related to injection drug use are common. Harm reduction strategies such as syringe exchange programs and skin care clinics aim to prevent these infections in injection drug users (IDUs). Syringe exchange programs are currently prohibited by law in Florida. The goal of this study was to estimate the mortality and cost of injection drug use-related bacterial infections over a 12-month period to the county safety-net hospital in Miami, Florida. Additionally, the prevalence of HIV and hepatitis C virus among this cohort of hospitalized IDUs was estimated.Methods and FindingsIDUs discharged from Jackson Memorial Hospital were identified using the International Classification of Diseases, Ninth Revision, codes for illicit drug abuse and endocarditis, bacteremia or sepsis, osteomyelitis and skin and soft tissue infections (SSTIs). 349 IDUs were identified for chart abstraction and 92% were either uninsured or had publicly funded insurance. SSTIs, the most common infection, were reported in 64% of IDUs. HIV seroprevalence was 17%. Seventeen patients (4.9%) died during their hospitalization. The total cost for treatment for injection drug use-related infections to Jackson Memorial Hospital over the 12-month period was $11.4 million.ConclusionsInjection drug use-related bacterial infections represent a significant morbidity for IDUs in Miami-Dade County and a substantial financial cost to the county hospital. Strategies aimed at reducing risk of infections associated with injection drug use could decrease morbidity and the cost associated with these common, yet preventable infections.

As general internists who work in the hospitals and outpatient clinics of a large safety-net health system in the Bronx, we care for an ever-increasing number of patients with symptoms of coronavirus disease 2019 (COVID-19) who call our clinics to ask for guidance, seek care in our hospitals, and die in our wards. We are distressed by the disproportionate burden of the COVID-19 pandemic for immigrant patients.The Bronx, a borough of New York City, is one of the most ethnically diverse urban areas in the US and ranked the least healthy of New York State's 62 counties. It has rates of chronic diseases such as asthma, diabetes, hypertension, obesity, and tobacco use disorder-all factors that appear to increase the risk of complications from COVID-19-that are among the highest in the state. 1 Poor health in the Bronx is due at least in part to decades of policies related to housing, education, environmental health, and criminal justice that have perpetuated racial and economic inequality. Unsurprisingly, the Bronx currently has the highest rate of COVID-19 diagnoses and deaths among New York City's boroughs. 2 More than half a million immigrants live in the borough, and most speak a language at home other than English. Immigrants in the Bronx are disproportionately represented in the essential workforce at risk for exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including physicians, nurses, nursing aides, home health aides, subway and bus drivers, grocery clerks, and others. The limited sociodemographic data available for COVID-19 cases in New York City show that Hispanic or Latinx individuals, who constitutemost immigrants in the Bronx, are considerably more likely to die of COVID-19 than white New York City residents. 3 As we care for patients in the community and in the hospital during this crisis, we are deeply troubled by some of the ways in which COVID-19 uniquely affects low-income immigrant patients. In these communities, the combination of high levels of chronic diseases, chronic stress, and less access to preventive health services 4 increases the risk of more severe SARS-CoV-2 infections. Many immigrant patients live in close quarters with multiple generations sharing bedrooms and bathrooms. In these families it is often impossible to isolate older family members, those with asthma or other comorbid conditions, or even those who are ill with COVID-19 from others in the household, including those who must continue to leave home to work.When conducting telemedicine visits because our clinics are shuttered, we routinely ask about COVID-19 symptoms and answer patients' questions. For immigrants with limited English proficiency, the lack of available translated information about the disease has meant relying on social media to obtain advice that may be

Innovative strategies are needed to increase access to and retention in oral health care for PLWHA. Key areas for action include developing strategies to reduce costs, increase access, and reduce personal barriers to receiving dental care, particularly considering the impact of poor oral health in this population.

BackgroundAntiretroviral therapy (ART) agents potentially associated with adverse metabolic profiles are commonly used in low- and middle-income countries. We assessed risk factors for cardiovascular disease (CVD)-related morbidity and mortality in a cohort of HIV-infected, ART-treated adults in Rio de Janeiro, Brazil.MethodsHospital records and mortality data between 2000–2010 were examined for incident CVD-related ICD-10 and Coding of Death in HIV diagnoses among adults ≥18 years old on ART, enrolled in an observational cohort. Poisson regression models assessed associations between demographic and clinical characteristics and ART agent or class on CVD event risk.ResultsOf 2960 eligible persons, 109 had a CVD event (89 hospitalizations, 20 deaths). Participants were 65 % male, 54 % white, and had median age of 37 and 4.6 years on ART. The median nadir CD4+ T lymphocyte count was 149 cells/mm3. The virologic suppression rate at the end of study follow-up was 60 %. In multivariable models, detectable HIV-1 RNA prior to the event, prior CVD, less time on ART, age ≥40 at study baseline, nadir CD4+ T lymphocyte count ≤50 cells/mm3, non-white race, male gender, and a history of hypertension were significantly associated with CVD event incidence (p < 0.05), in order of decreasing strength. In multivariate models, cumulative use of tenofovir, zidovudine, efavirenz and ritonavir-boosted atazanavir, darunavir and/or lopinavir were associated with decreased CVD event risk. Recent tenofovir and boosted atazanavir use were associated with decreased risk, while recent stavudine, nevirapine and unboosted nelfinavir and/or indinavir use were associated with increased CVD event risk.ConclusionsVirologic suppression and preservation of CD4+ T-lymphocyte counts were as important as traditional CVD risk factor burden in determining incident CVD event risk, emphasizing the overall benefit of ART on CVD risk and the need for metabolically-neutral first- and second-line ART in resource-limited settings.Electronic supplementary materialThe online version of this article (doi:10.1186/s12879-016-1735-4) contains supplementary material, which is available to authorized users.

Objectives Trichomoniasis (TV) is associated with an increased risk of acquisition of sexually transmitted diseases (STDs) and HIV. The purpose of this study is to evaluate factors associated with incidence TV among female STD clinic attendees in the USA. Methods Data were collected from women participating in a randomised controlled trial evaluating brief risk reduction counselling at the time of HIV testing to reduce sexually transmitted infections (STIs) incidence in STD clinics. Participants recruited from STD clinics underwent STI testing at baseline and 6-month follow-up. TV testing was performed using Nucleic Acid Amplification Test. Results 1704 participants completed study assessments. Prevalence of TV was 14.6%, chlamydia 8.6%, gonorrhoea 3.0%, herpes simplex virus 2 44.7% and HIV 0.4%. Cumulative 6-month incidence of TV was 7.5%. Almost 50% of the incident TV cases had TV at baseline and had received treatment. Factors associated with incidence of TV were having chlamydia, TV and HIV at baseline: TV relative risk (RR)=3.37 (95% CI 2.35 to 4.83, p<0.001); chlamydia RR=1.92 (95% CI 1.23 to 2.99, p=0.04); and HIV=1.59 (95% CI 1.01 to 2.50, p=0.047). Conclusions Prevalent and incident TV is common among STD clinic attendees; and baseline TV is the main risk factor for incident TV, suggesting high rates of reinfection or treatment failures. This supports the importance of rescreening women after treatment for TV, evaluating current treatment regimens and programmes to ensure treatment of sexual partners. Clinical trial number NCT01154296.
