Toward Community Empowerment: The Puerto Rican .

People who inject drugs (PWID) who migrate from Puerto Rico (PR) to New York City (NYC) are at elevated risk for hepatitis C (HCV), HIV and drug overdose. There is an urgent need to identify a sustainable path toward improving the health outcomes of this population. Peer-driven HIV/HCV prevention interventions for PWID are effective in reducing risk behaviors.

Effects of neuromuscular blocking drugs on viability of human umbilical vein endothelial cells (HUVECs).

Objective: This study aimed to investigate the effects of neuromuscular blocking drugs on the viability of human umbilical vein endothelial cells (HUVECs) and to investigate whether they cause vascular complications due to cell proliferation.

Methods: HUVECs were cultivated with 5% CO at 37°C in a predefined supplemented medium over 7 days until confluence of cell monolayers. Assays were conducted during the exponential growth phase.

Pre- and post-bone marrow harvest anaemia is associated with lower CD34+ stem cell collection, high harvest volume and female gender.

Background: Donor safety is paramount when performing bone marrow stem cell harvest. The incidence of full blood count (FBC) abnormalities among donors and variables associated with anaemia after marrow harvest are not well established.

Aims: To describe the frequency of FBC abnormalities prior to bone marrow stem cell harvest and to identify variables associated with post harvest anaemia.

Injection risk norms and practices among migrant Puerto Rican people who inject drugs in New York City: The limits of acculturation theory.

Background: Among people who inject drugs (PWID) in New York City (NYC), racial minorities are disproportionately infected with HIV and hepatitis C (HCV). Prior research has shown that PWID who started injecting drugs in Puerto Rico (P.R.

Substance Use Among Older People Living With HIV: Challenges for Health Care Providers.

Older people living with HIV (OPLWH) have higher rates of substance use (tobacco, alcohol, and other drugs) than their HIV-negative peers. Addressing health care needs of OPLWH who use substances is more challenging than for those who do not: they are highly impacted by comorbid conditions, substance use can interact with other medications (including antiretroviral therapy-ART) and reduce their effectiveness, and substance use has been associated with reduced adherence to ART and increased risky behaviors (including sexual risks). People who use substances also suffer disparities along the HIV continuum of care, resulting in lower viral suppression rates and poorer health outcomes.

Rescue haploidentical peripheral blood stem cell transplantation for engraftment failure: a single-centre case series.

Graft failure affects approximately 5% of allogeneic stem cell transplants, with a poor prognosis. Salvage second allogeneic stem cell transplantation (alloSCT2) is limited by high rates of transplant-related mortality from infection and graft-versus-host disease. We report on five adult patients receiving rescue alloSCT2 using haploidentical peripheral blood stem cells.

Continuing Links Between Substance Use and HIV Highlight the Importance of Nursing Roles.

Links between HIV and substance use were identified early in the U.S. HIV epidemic.

Barriers and facilitators to successful transition from long-term residential substance abuse treatment.

Although residential substance abuse treatment has been shown to improve substance use and other outcomes, relapse is common. This qualitative study explores factors that hinder and help individuals during the transition from long-term residential substance abuse treatment to the community. Semi-structured interviews were conducted with 32 individuals from residential substance abuse treatment.

Brief Report: The Relationship Between Injection Drug Use Risk Behaviors and Markers of Immune Activation.

High levels of immune activation are reported for people who inject drugs. Studies of the relationship between injection behaviors and immune activation have yielded mixed results, in part due to lack of control for hepatitis C virus in analyses. This study, of 48 HIV-seronegative people who inject drugs, examines this relationship controlling for hepatitis C virus viremia.

Chronic Hepatitis C Virus Infection and the Proinflammatory Effects of Injection Drug Use.

Background:  Chronic inflammation, as defined by persistent immune activation, is associated with adverse clinical outcomes. People who inject drugs (PWID) have evidence of persistent immune activation. Here, in a cohort of PWID with or without hepatitis C virus (HCV) infection, we sought to dissect out the contribution of chronic HCV infection (common in PWID) from the effects of injection drug use itself.

Challenges in Recruiting People Who Use Drugs for HIV-Related Biomedical Research: Perspectives from the Field.

Recruitment of people who use drugs (PWUD) for HIV-related research has been undertaken since early in the epidemic. In early studies, recruitment was often performed by outreach workers with familiarity with the target population, who distributed risk reduction materials, and administered the surveys being conducted on drug use and risk behaviors. The evolution of effective treatments for HIV has provided opportunities for PWUD to participate in biobehavioral studies testing the efficacy of medical treatment advances and exploring the underlying biomedical basis for prevention and treatment efforts.

Behavioural, Mucosal and Systemic Immune Parameters in HIV-infected and Uninfected Injection Drug Users.

Objective: Injection drug use (IDU) remains a major risk factor for HIV-1 acquisition. The complex interplay between drug use, non-sterile injection, and Hepatitis C remains poorly understood. We conducted a pilot study to determine the effect of IDU on immune parameters among HIV-uninfected and -infected individuals.

Asymptomatic bacteriuria screened by catheterized samples at pregnancy term in women undergoing cesarean delivery.

Objective: The objective of this study was to assess the frequency of urinary tract infection (UTI) with urine samples obtained via catheterization among women undergoing cesarean delivery at term pregnancy.

Materials And Methods: A cross-sectional study involving 159 women in whom cesarean delivery was conducted at term pregnancy after a regular follow-up from first to third trimester. For screening and diagnosis of UTI during antenatal period, the authors used dipstick test and microscopic urinalysis, and urine culture was used in the presence of symptomatic UTI unresponsive to initial antibiotic therapy.

Opioid Use Trajectories, Injection Drug Use, and Hepatitis C Virus Risk Among Young Adult Immigrants from the Former Soviet Union Living in New York City.

Available evidence suggests that young former Soviet Union immigrants in New York City have high rates of non-medical prescription opioid and heroin use, drug injection and injection-related risk behavior, making them vulnerable to hepatitis C virus (HCV)/human immunodeficiency virus (HIV) infection, overdose and associated harms. This group has been the focus of little research, however. This paper presents quantitative and qualitative data from 80 former Soviet immigrants (ages 18-29) to characterize their opioid use trajectories, injection risk behavior, HCV/HIV testing histories and self-reported HCV/HIV serostatus, and provides clinically meaningful data to inform tailored education, prevention and harm reduction interventions.

Influence of Stem Cell Source on Outcomes of Allogeneic Reduced-Intensity Conditioning Therapy Transplants Using Haploidentical Related Donors.

We compared outcomes for 2 retrospective cohorts of patients undergoing reduced-intensity conditioning (RIC) therapy transplants using haploidentical related donors and post-transplant prophylaxis against graft-versus-host disease (GVHD) with high-dose cyclophosphamide, tacrolimus, and mycophenolate. The first cohort of 13 was transplanted with bone marrow (BM) as the stem cell source, whereas the second cohort of 23 used peripheral blood stem cells (PBSCs) mobilized with granulocyte colony-stimulating factor. The BM cohort received a single 60-mg/kg dose of cyclophosphamide on day +3, whereas the PBSC cohort received 2 doses on days +3 and +4.

Gender-Specific HIV Prevention Interventions for Women Who Use Alcohol and Other Drugs: The Evolution of the Science and Future Directions.

The use of alcohol and other drugs (AODs) is an important driver of gender disparities in HIV prevalence. Consequently, there is a need for women-specific HIV interventions that are conceptualized to address (1) women's risk behavior, their roles in sexual relationships, and gender power dynamics and (2) other issues commonly faced by women who use AODs, such as gender-based violence and victimization. This article presents the evolution of HIV prevention intervention research with women who use AODs.

Single-Agent High-Dose Cyclophosphamide for Graft-versus-Host Disease Prophylaxis in Human Leukocyte Antigen-Matched Reduced-Intensity Peripheral Blood Stem Cell Transplantation Results in an Unacceptably High Rate of Severe Acute Graft-versus-Host Disease.

High-dose cyclophosphamide given early after allogeneic hemopoietic cell transplantation has been shown to be effective prophylaxis against graft-versus-host disease (GVHD) in the setting of HLA-matched myeloablative bone marrow grafts, allowing avoidance of long-term immunosuppression with calcineurin inhibitors in some patients. Whether this approach is feasible using granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood stem cell grafts is unknown. We conducted an exploratory phase 2 trial of cyclophosphamide given at 50 mg/kg i.

Addressing the HIV/AIDS epidemic among Puerto Rican people who inject drugs: the need for a multiregion approach.

High levels of HIV risk behaviors and prevalence have been reported among Puerto Rican people who inject drugs (PRPWID) since early in the HIV epidemic. Advances in HIV prevention and treatment have reduced HIV among people who inject drugs (PWID) in the United States. We examined HIV-related data for PRPWID in Puerto Rico and the US Northeast to assess whether disparities continue.

Latinas with elevated fasting plasma glucose: an analysis using NHANES 2009-2010 data.

For Latinas with fasting plasma glucose (FPG) levels in the prediabetes and diabetes ranges, early detection can support steps to optimize their health. Data collected in 2009-2010 indicate that 36.7% of Latinas in the United States had elevated FPG levels.

HIV and aging: state of knowledge and areas of critical need for research. A report to the NIH Office of AIDS Research by the HIV and Aging Working Group.

HIV risk behaviors, susceptibility to HIV acquisition, progression of disease after infection, and response to antiretroviral therapy all vary by age. In those living with HIV, current effective treatment has increased the median life expectancy to >70 years of age. Biologic, medical, individual, social, and societal issues change as one ages with HIV infection, but there has been only a small amount of research in this field.
