Validation of Retention in HIV Care Status Using the New York City HIV Surveillance Registry and Clinical Care Data From a Large HIV Care Center.

Context: Improving retention in care is a key element of the National HIV/AIDS Strategy (NHAS). However, definitions for measuring retention in care are not standardized.

Objective: To compare measures of retention based on both clinic visit data and HIV laboratory surveillance data.

Supplemental Learning in the Laboratory: An Innovative Approach for Evaluating Knowledge and Method Transfer.

The Multi-Rule Quality Control System (MRQCS) is a tool currently employed by the Centers for Disease Control and Prevention (CDC) to evaluate and compare laboratory performance. We have applied the MRQCS to a comparison of instructor and computer-led pre-laboratory lectures for a supplemental learning experiment. Students in general chemistry and analytical chemistry from both two- and four-year institutions performed two laboratory experiments as part of their normal laboratory curriculum.

Pharmacokinetics, Safety, and Efficacy of Recombinant Factor VIII Fc Fusion Protein: A Practical Review.

Prophylaxis for hemophilia A with conventional factor VIII (FVIII) products requires frequent intravenous dosing, which may reduce adherence. Recombinant factor VIII Fc fusion protein (rFVIIIFc) has a prolonged half-life compared with conventional rFVIII, and has demonstrated safety and efficacy for the prevention and treatment of bleeding episodes in phase 3 studies of patients with severe hemophilia A. Most subjects experienced reduced prophylactic dosing frequency with rFVIIIFc compared with prestudy FVIII; the median total weekly prophylactic consumption was comparable.

Caffeine Concentrations in Coffee, Tea, Chocolate, and Energy Drink Flavored E-liquids.

Introduction: Most electronic cigarettes (e-cigarettes) contain a solution of propylene glycol/glycerin and nicotine, as well as flavors. E-cigarettes and their associated e-liquids are available in numerous flavor varieties. A subset of the flavor varieties include coffee, tea, chocolate, and energy drink, which, in beverage form, are commonly recognized sources of caffeine.

A Community Health Record: Improving Health Through Multisector Collaboration, Information Sharing, and Technology.

We present a framework for developing a community health record to bring stakeholders, information, and technology together to collectively improve the health of a community. It is both social and technical in nature and presents an iterative and participatory process for achieving multisector collaboration and information sharing. It proposes a methodology and infrastructure for bringing multisector stakeholders and their information together to inform, target, monitor, and evaluate community health initiatives.

Innovative Use of Existing Public and Private Data Sources for Postmarketing Surveillance of Central Line-Associated Bloodstream Infections Associated With Intravenous Needleless Connectors.

The Centers for Medicare and Medicaid Services (CMS) Hospital Compare central line-associated bloodstream infection (CLABSI) data and private databases containing new-generation intravenous needleless connector (study NC) use at the hospital level were linked. The relative risk (RR) of CLABSI associated with the study NCs was estimated, adjusting for hospital characteristics. Among 3074 eligible hospitals in the 2013 CMS database, 758 (25%) hospitals used the study NCs.

A high-throughput UHPLC-MS/MS method for the quantification of five aged butyrylcholinesterase biomarkers from human exposure to organophosphorus nerve agents.

Organophosphorus nerve agents (OPNAs) are toxic compounds that are classified as prohibited Schedule 1 chemical weapons. In the body, OPNAs bind to butyrylcholinesterase (BChE) to form nerve agent adducts (OPNA-BChE). OPNA-BChE adducts can provide a reliable, long-term protein biomarker for assessing human exposure.

Quantification of Toxins in Soapberry (Sapindaceae) Arils: Hypoglycin A and Methylenecyclopropylglycine.

Methylenecyclopropylglycine (MCPG) and hypoglycin A (HGA) are naturally occurring amino acids found in some soapberry fruits. Fatalities have been reported worldwide as a result of HGA ingestion, and exposure to MCPG has been implicated recently in the Asian outbreaks of hypoglycemic encephalopathy. In response to an outbreak linked to soapberry ingestion, the authors developed the first method to simultaneously quantify MCPG and HGA in soapberry fruits from 1 to 10 000 ppm of both toxins in dried fruit aril.

Case diagnosis and characterization of suspected paralytic shellfish poisoning in Alaska.

Clinical cases of paralytic shellfish poisoning (PSP) are common in Alaska, and result from human consumption of shellfish contaminated with saxitoxin (STX) and its analogues. Diagnosis of PSP is presumptive and based on recent ingestion of shellfish and presence of manifestations consistent with symptoms of PSP; diagnosis is confirmed by detection of paralytic shellfish toxins in a clinical specimen or food sample. A clinical diagnostic analytical method using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was used to evaluate the diagnosis of saxitoxin-induced PSP (STX-PSP) in 11 Alaskan patients using urine specimens collected between June 2010 and November 2011.

Prescription Drug Monitoring Programs Are Associated With Sustained Reductions In Opioid Prescribing By Physicians.

State prescription drug monitoring programs are promising tools to rein in the epidemic of prescription opioid overdose. We used data from a national survey to assess the effects of these programs on the prescribing of opioid analgesics and other pain medications in ambulatory care settings at the point of care in twenty-four states from 2001 to 2010. We found that the implementation of a prescription drug monitoring program was associated with more than a 30 percent reduction in the rate of prescribing of Schedule II opioids.

Integration of Multiplex Bead Assays for Parasitic Diseases into a National, Population-Based Serosurvey of Women 15-39 Years of Age in Cambodia.

Collection of surveillance data is essential for monitoring and evaluation of public health programs. Integrated collection of household-based health data, now routinely carried out in many countries through demographic health surveys and multiple indicator surveys, provides critical measures of progress in health delivery. In contrast, biomarker surveys typically focus on single or related measures of malaria infection, HIV status, vaccination coverage, or immunity status for vaccine-preventable diseases (VPD).

Four aspects of the scope and quality of family planning services in US publicly funded health centers: Results from a survey of health center administrators.

Objectives: This study aims to describe aspects of the scope and quality of family planning services provided by US publicly funded health centers before the release of relevant federal recommendations.

Study Design: Using nationally representative survey data (N=1615), we describe four aspects of service delivery: family planning services provided, contraceptive methods provided onsite, written contraceptive counseling protocols and youth-friendly services. We created a count index for each issue and used multivariable ordered logistic regression to identify health center characteristics associated with scoring higher on each.

Quantification of Hydrazine in Human Urine by HPLC-MS-MS.

Currently used on F-16 fighter jets and some space shuttles, hydrazine could be released at toxic levels to humans as a result of an accidental leakage or spill. Lower-level exposures occur in industrial workers or as a result of the use of some pharmaceuticals. A method was developed for the quantitation of hydrazine in human urine and can be extended by dilution with water to cover at least six orders of magnitude, allowing measurement at all clinically significant levels of potential exposure.

Simultaneous Measurement of 3-Chlorotyrosine and 3,5-Dichlorotyrosine in Whole Blood, Serum and Plasma by Isotope Dilution HPLC-MS-MS.

Chlorine is a public health concern and potential threat due to its high reactivity, ease and scale of production, widespread industrial use, bulk transportation, massive stockpiles and history as a chemical weapon. This work describes a new, sensitive and rapid stable isotope dilution method for the retrospective detection and quantitation of two chlorine adducts. The biomarkers 3-chlorotyrosine (Cl-Tyr) and 3,5-dichlorotyrosine (Cl2-Tyr) were isolated from the pronase digest of chlorine exposed whole blood, serum or plasma by solid-phase extraction (SPE), separated by reversed-phase HPLC and detected by tandem mass spectrometry (MS-MS).

Toward a Mechanistic Understanding of Environmentally Forced Zoonotic Disease Emergence: Sin Nombre Hantavirus.

Understanding the environmental drivers of zoonotic reservoir and human interactions is crucial to understanding disease risk, but these drivers are poorly predicted. We propose a mechanistic understanding of human-reservoir interactions, using hantavirus pulmonary syndrome as a case study. Crucial processes underpinning the disease's incidence remain poorly studied, including the connectivity among natural and peridomestic deer mouse host activity, virus transmission, and human exposure.

Disability and Risk of Recent Sexual Violence in the United States.

Objectives: To examine the relative prevalence of recent (past 12 months) penetrative and nonpenetrative sexual violence comparing men and women with and without a disability.

Methods: Data are from the 2010 National Intimate Partner and Sexual Violence Survey, a national telephone survey of US adults, and includes an expansive measure of sexual violence victimization. A total of 9086 women and 7421 men completed the telephone survey in 2010.

Slow Progress In Finalizing Measles And Rubella Elimination In The European Region.

All countries in the World Health Organization European Region committed to eliminating endemic transmission of measles and rubella by 2015, and disease incidence has decreased dramatically. However, there was little progress between 2012 and 2013, and the goal will likely not be achieved on time. Genuine political commitment, increased technical capacity, and greater public awareness are urgently needed, especially in Western Europe.

The Global Polio Eradication Initiative: Progress, Lessons Learned, And Polio Legacy Transition Planning.

The world is closer than ever to achieving global polio eradication, with record-low polio cases in 2015 and the impending prospect of a polio-free Africa. Tens of millions of volunteers, social mobilizers, and health workers have participated in the Global Polio Eradication Initiative. The program contributes to efforts to deliver other health benefits, including health systems strengthening.

Characterization of Bacterial Communities in Selected Smokeless Tobacco Products Using 16S rDNA Analysis.

The bacterial communities present in smokeless tobacco (ST) products have not previously reported. In this study, we used Next Generation Sequencing to study the bacteria present in U.S.

For Working-Age Cancer Survivors, Medical Debt And Bankruptcy Create Financial Hardships.

The rising medical costs associated with cancer have led to considerable financial hardship for patients and their families in the United States. Using data from the LIVESTRONG 2012 survey of 4,719 cancer survivors ages 18-64, we examined the proportions of survivors who reported going into debt or filing for bankruptcy as a result of cancer, as well as the amount of debt incurred. Approximately one-third of the survivors had gone into debt, and 3 percent had filed for bankruptcy.

The Risk of Nosocomial Transmission of Rift Valley Fever.

In 2000, we investigated the Rift Valley fever (RVF) outbreak on the Arabian Peninsula-the first outside Africa-and the risk of nosocomial transmission. In a cross-sectional design, during the peak of the epidemic at its epicenter, we found four (0.6%) of 703 healthcare workers (HCWs) IgM seropositive but all with only community-associated exposures.

Racial Discrimination and HIV-related Risk Behaviors in Southeast Louisiana.

Objectives: We examined the relationship between cumulative experiences of racial discrimination and HIV-related risk taking, and whether these relationships are mediated through alcohol use among African Americans in semi-rural southeast Louisiana.

Methods: Participants (N = 214) reported on experiences of discrimination, HIV sexual risk-taking, history of sexually transmitted infection (STI), and health behaviors including alcohol use in the previous 90 days. Experiences of discrimination (scaled both by frequency of occurrence and situational counts) as a predictor of a sexual risk composite score as well as a history of STI was assessed using multivariate linear and logistic regression, respectively, including tests for mediation by alcohol use.

Estimating the Size and Cost of the STD Prevention Services Safety Net.

The Patient Protection and Affordable Care Act is expected to reduce the number of uninsured people in the United States during the next eight years, but more than 10% are expected to remain uninsured. Uninsured people are one of the main populations using publicly funded safety net sexually transmitted disease (STD) prevention services. Estimating the proportion of the uninsured population expected to need STD services could help identify the potential demand for safety net STD services and improve program planning.

Nearly Half Of US Adults Living With HIV Received Federal Disability Benefits In 2009.

The effects of HIV infection on national labor-force participation have not been rigorously evaluated. Using data from the Medical Monitoring Project and the National Health Interview Survey, we present nationally representative estimates of the receipt of disability benefits by adults living with HIV receiving care compared with the general US adult population. We found that in 2009, adults living with HIV were nine times more likely than adults in the general population to receive disability benefits.
