RESUMEN

CONTEXT: In 2008, the $1.2 M sexually transmitted disease (STD) services line item supporting STD clinical services by the Massachusetts Department of Public Health was eliminated, forcing the cessation of all state-supported STD service delivery. OBJECTIVE: To determine the impact on community provision of STD services after the elimination of state funds supporting STD service provision. DESIGN AND SETTING: Rapid ethnographic assessments were conducted in May 2010 and September 2013 to better understand the impact of budget cuts on STD services in Massachusetts. The rapid ethnographic assessment teams identified key informants through Massachusetts's STD and human immunodeficiency virus programs. PARTICIPANTS: Fifty providers/clinic administrators in 19 sites (15 unique) participated in a semistructured interview (community health centers [n = 10; 53%], hospitals [n = 4; 21%], and other clinical settings [n = 5; 26%]). RESULTS: Results clustered under 3 themes: financial stability of agencies/clinics, the role insurance played in the provision of STD care, and perceived clinic capacity to offer appropriate STD services. Clinics faced hard choices about whether to provide care to patients or refer elsewhere patients who were unable or unwilling to use insurance. Clinics that decided to see patients regardless of ability to pay often found themselves absorbing costs that were then passed along to their parent agency; the difficulty and financial strain incurred by a clinic's parent agency by providing STD services without support by state grant dollars emerged as a primary concern. Meeting patient demand with staff with appropriate training and expertise remained a concern. CONCLUSIONS: Provision of public health by private health care providers may increase concern among some community provision sites about the sustainability of service provision absent external funds, either from the state or from the third-party billing. Resource constraints may be felt across clinic operations. Provision of public health in the for-profit health system involves close consideration of resources, including those: leveraged, used to provide uncompensated care, or available for collection through third-party billing.

RESUMEN

BACKGROUND: Recent evidence indicates increased use of urgent care centers (UCCs) for sexually transmitted disease (STD) testing. We sought to learn more about STD services in UCCs in a large metropolitan area. METHOD: Using a modified rapid gap assessment approach, we interviewed staff from 19 UCCs in metro Atlanta, GA. The UCCs were identified using two online search engines. We focused on a 50-mile radius around Atlanta. We then excluded duplicates and closed UCCs, and the ones outside Atlanta's five contiguous counties. Using a prioritization process, we visited UCCs in or adjacent to areas with mid to high local STD morbidity, or facilities from which STD cases were reported the year prior. We collected checklist-based data on STD testing, treatment, and preventive services, as well as supportive services (eg, substance use/mental health referrals). Checklist data, notes, and open-ended questions were summarized and analyzed descriptively. RESULTS: All UCCs (n = 19) reported offering basic to comprehensive STD testing. Although most could treat on-site for chlamydia and gonorrhea, most relied on referrals, or prescriptions and "return to facility" practices to treat syphilis. Sources for STD information/management included the health department/Centers for Disease Control and Prevention, online medical sites, and electronic medical record embedded information. Challenges UCCs acknowledged included staying up-to-date with treatment guidance and laboratory reporting requirements, inadequate time for sexual risk reduction counseling, and linking patients with extended care needs (eg, HIV+ case management, supportive services), or following up with patients. CONCLUSIONS: Urgent cares are STD testing resources. Service availability varies, but opportunities exist to enhance STD services in UCC settings and in communities.

RESUMEN

Cell penetrating peptides (CPPs) offer great potential to deliver therapeutic molecules to previously inaccessible intracellular targets. However, many CPPs are inefficient and often leave their attached cargo stranded in the cell's endosome. We report a versatile platform for the isolation of peptides delivering a wide range of cargos into the cytoplasm of cells. We used this screening platform to identify multiple "Phylomer" CPPs, derived from bacterial and viral genomes. These peptides are amenable to conventional sequence optimization and engineering approaches for cell targeting and half-life extension. We demonstrate potent, functional delivery of protein, peptide, and nucleic acid analog cargos into cells using Phylomer CPPs. We validate in vivo activity in the cytoplasm, through successful transport of an oligonucleotide therapeutic fused to a Phylomer CPP in a disease model for Duchenne's muscular dystrophy. This report thus establishes a discovery platform for identifying novel, functional CPPs to expand the delivery landscape of druggable intracellular targets for biological therapeutics.

RESUMEN

BACKGROUND: Congenital syphilis (CS) disproportionately affects racial and ethnic minority women, especially in the US South. Although CS is relatively easy and inexpensive to prevent through screening and treatment of pregnant women, CS cases have continued to rise and are concentrated in relatively few US counties and states. In 2010, Louisiana had the highest case rate in the country for primary, secondary, and CS, with the highest number of CS cases in northwest Louisiana, where Shreveport is located. METHODS: We conducted qualitative interviews with community members (women and frontline providers) living in Caddo Parish to obtain their views about factors that negatively impact CS prevention. RESULTS: Participants described impediments in the pathways for prevention of CS. Lack of sexual and reproductive health education, discontinuities and fragmentation in health care insurance coverage, a dearth of referral points for prenatal care, and difficulty finding prenatal care providers who accept Medicaid can delay timely and adequate care for pregnant women. Participants reported that low reimbursement for necessary injections and difficulty obtaining required medication challenged efforts to screen and treat pregnant women according to guidelines. CONCLUSIONS: Although CS is easily prevented, health system and policy obstacles in pathways to CS prevention and care may need remediation at state and local levels.

RESUMEN

BACKGROUND: Congenital syphilis occurs when a pregnant woman with syphilis is not diagnosed or treated and the infection is passed in utero, causing severe infant morbidity and mortality. Congenital syphilis is easily prevented if women receive timely and adequate prenatal care. Cases of congenital syphilis are considered indicators of problems in the safety net. However, maternal social and behavioral factors can impede women's care, even when providers follow guidelines. METHODS: We reviewed case interviews and maternal records for 23 congenital syphilis cases reported to the Centers for Disease Control and Prevention from Indiana between 2014 and 2016. We used qualitative methods to analyze narrative notes from maternal interviews to learn more about factors that potentially contributed to congenital syphilis cases. RESULTS: All providers followed Centers for Disease Control and Prevention and state recommendations for screening and treatment for pregnant women with syphilis. Twenty-one of 23 women had health insurance. The number of prenatal care visits women had was suboptimal; more than one third of women had no prenatal care. Nearly one third of women's only risk factor was sex with a primary male sex partner. The majority of women suffered social vulnerabilities, including homelessness, substance abuse, and incarceration. CONCLUSIONS: Despite provider adherence to guidelines and health insurance availability, some pregnant women with syphilis are unlikely to receive timely diagnosis and treatment. Pregnant women at high risk for syphilis may need additional social and material support to prevent a congenital syphilis case. Additional efforts are needed to reach the male partners of vulnerable females with syphilis.

RESUMEN

BACKGROUND: During the 2014-2016 West Africa Ebola Virus Disease (EVD) epidemic, the public health community had concerns that sexual transmission of the Ebola virus (EBOV) from EVD survivors was a risk, due to EBOV persistence in body fluids of EVD survivors, particularly semen. The Sierra Leone Ebola Virus Persistence Study was initiated to investigate this risk by assessing EBOV persistence in numerous body fluids of EVD survivors and providing risk reduction counseling based on test results for semen, vaginal fluid, menstrual blood, urine, rectal fluid, sweat, tears, saliva, and breast milk. This publication describes implementation of the counseling protocol and the key lessons learned. METHODOLOGY/PRINCIPAL FINDINGS: The Ebola Virus Persistence Risk Reduction Behavioral Counseling Protocol was developed from a framework used to prevent transmission of HIV and other sexually transmitted infections. The framework helped to identify barriers to risk reduction and facilitated the development of a personalized risk-reduction plan, particularly around condom use and abstinence. Pre-test and post-test counseling sessions included risk reduction guidance, and post-test counseling was based on the participants' individual test results. The behavioral counseling protocol enabled study staff to translate the study's body fluid test results into individualized information for study participants. CONCLUSIONS/SIGNIFICANCE: The Ebola Virus Persistence Risk Reduction Behavioral Counseling Protocol provided guidance to mitigate the risk of EBOV transmission from EVD survivors. It has since been shared with and adapted by other EVD survivor body fluid testing programs and studies in Ebola-affected countries.

RESUMEN

During 2010-2014, urgent care centers saw a ≈2-fold increase in the number of visits for chlamydia and gonorrhea testing and a >3-fold increase in visits by persons with diagnosed sexually transmitted infections. As urgent care becomes more popular, vigilance is required to ensure proper management of these diseases.

RESUMEN

BACKGROUND: In 2008, the line item supporting sexually transmitted disease (STD) services in the Massachusetts state budget was cut as a result of budget shortfalls. Shortly thereafter, direct provision of STD clinical services supported by the Massachusetts Department of Public Health (MDPH) was suspended. Massachusetts Department of Public Health requested an initial assessment of its internal response and impact in 2010. A follow-up assessment occurred in September 2013. METHODS: In 2010 and 2013, 39 and 46 staff, respectively, from MDPH and from clinical partner agencies, were interviewed about changes in the role of the MDPH, partnerships, STD services, challenges, and recommendations. Interview notes were summarized, analyzed, and synthesized by coauthors using qualitative analysis techniques and NVivo software. RESULTS: The withdrawal of state funding for STD services, and the subsequent reduction in clinical service hours, erected numerous barriers for Disease Intervention Specialists (DIS) seeking to ensure timely STD treatment for index cases and their partners. After initial instability, MDPH operations stabilized due partly to strong management, new staff, and intensified integration with human immunodeficiency virus services. Existing contracts with human immunodeficiency virus providers were leveraged to support alternative STD testing and care sites. Massachusetts Department of Public Health strengthened its clinical and epidemiologic expertise. The DIS expanded their scope of work and were outposted to select new sites. Challenges remained, however, such as a shortage of DIS staff to meet the needs. CONCLUSIONS: Although unique in many ways, MA offers experiences and lessons for how a state STD program can adapt to a changing public health context.

RESUMEN

Assessment is a core function in sexually transmitted disease (STD) prevention and control programs. Assessment is more than reviewing case report data; it includes taking into consideration an array of data of various sources and types to be able to respond to emerging disease threats, align human and financial resources, and plan for the future. In this article, we outline key assessment domains, data sources, activities, and methods for STD programs. We present an illustrative case study of how assessment can be used to identify effective interventions for STD control.

RESUMEN

Efficient cargo uptake is essential for cell-penetrating peptide (CPP) therapeutics, which deliver widely diverse cargoes by exploiting natural cell processes to penetrate the cell's membranes. Yet most current CPP activity assays are hampered by limitations in assessing uptake, including confounding effects of conjugated fluorophores or ligands, indirect read-outs requiring secondary processing, and difficulty in discriminating internalization from endosomally trapped cargo. Split-complementation Endosomal Escape (SEE) provides the first direct assay visualizing true cytoplasmic-delivery of proteins at biologically relevant concentrations. The SEE assay has minimal background, is amenable to high-throughput processes, and adaptable to different transient and stable cell lines. This split-GFP-based platform can be useful to study transduction mechanisms, cellular imaging, and characterizing novel CPPs as pharmaceutical delivery agents in the treatment of disease.

RESUMEN

BACKGROUND: Social networking sites have become increasingly popular venues for meeting sex partners. Today, some sexually transmitted disease (STD) programs conduct Internet-based partner services (IPS). The purpose of the study was to explore how the Internet is being used by STD prevention programs to perform partner services. METHODS: We assessed US STD prevention programs receiving funds through the 2008-2013 Comprehensive STD Prevention Systems cooperative agreement. We (1) reviewed 2009 IPS protocols in 57 funding applications against a benchmark of national guidelines and (2) surveyed persons who conducted IPS in jurisdictions conducting IPS in 2012. RESULTS: Of the 57 project areas receiving Comprehensive STD Prevention Systems funds, 74% provided an IPS protocol. States with IPS protocols had larger populations and more gonorrhea and syphilis cases (t = 2.2-2.6; all Ps < .05), although not higher rates of infection. Most protocols included staffing (92%) and IPS documentation (87%) requirements, but fewer had evaluation plans (29%) or social networking site engagement strategies (16%). Authority to perform a complete range of IPS activities (send e-mail, use social networking sites) was associated with contacting more partners via IPSs (P < .05). CONCLUSIONS: This study provides a snapshot of IPS activities in STD programs in the United States. Further research is needed to move from assessment to generating data that can assist training efforts and program action and, finally, to enable efficient IPS programs that are integrated into STD prevention and control efforts.

RESUMEN

HIV risk perceptions and behaviors of 236 commercial sex workers from three major Mozambican urban centers were studied using the International Rapid Assessment, Response and Evaluation (I-RARE) methodology. All were offered HIV testing and, in Maputo, syphilis testing was offered as well. Sixty-three of the 236 opted for HIV testing, with 30 (48%) testing positive for HIV. In Maputo, all 30 receiving HIV tests also had syphilis testing, with 6 (20%) found to be positive. Results include interview excerpts and qualitative results using I-RARE methodology and AnSWR-assisted analyses of the interviews and focus group sessions.

RESUMEN

Recent studies have documented frequent use of female sex workers among Latino migrant men in the southeastern United States, yet little is known about the context in which sex work takes place, or the women who provide these services. As anthropologists working in applied public health, we use rapid ethnographic assessment as a technical assistance tool to document local understandings of the organization and typology of sex work and patterns of mobility among sex workers and their Latino migrant clients. By incorporating ethnographic methods in traditional public health needs assessments, we were able to highlight the diversity of migrant experiences and better understand the health needs of mobile populations more broadly. We discuss the findings in terms of their practical implications for HIV/STD prevention and call on public health to incorporate the concept of mobility as an organizing principle for the delivery of health care services.

RESUMEN

BACKGROUND: Little is known about the structure and context of, and the risks encountered in, sex work in the United States. OBJECTIVE: This community-based participatory research (CBPR) study explored female sex work and the feasibility of conducting a larger study of sex work within the immigrant Latino community in North Carolina. METHODS: Twelve abbreviated life story interviews were conducted with Latina women who sold sex, other women who sold sex to Latino men, and Latino men who hired sex workers. Content analysis was used to analyze narrative data. RESULTS: Themes emerged to describe the structure of sex work, motivations to sell and hire sex, and the sexual health-related needs of sex workers. Lessons learned included the ease of recruiting sex workers and clients, the need to develop relationships with controllers and bar owners/managers, and the high compensation costs to reimburse sex workers for participation. CONCLUSIONS: Study findings suggest that it is possible to identify and recruit sex workers and clients and collect formative data within this highly vulnerable and neglected community; the prevention of HIV and STDs is a priority among sex workers, and the need for a larger study to include non-Latino men who report using Latina sex workers, other community insiders (e.g., bartenders), and service providers for Latina sex workers.

RESUMEN

Prevalence of HIV infection in Botswana is among the highest in the world, at 23.9% of 15 - 49-year-olds. Most HIV testing is conducted in voluntary counselling and testing centres or medical settings. Improved access to testing is urgently needed. This qualitative study assessed and documented community perceptions about the concept of door-to-door HIV counselling and rapid testing in two of the highest-prevalence districts of Botswana. Community members associated many positive benefits with home-based, door-to-door HIV testing, including convenience, confidentiality, capacity to increase the number of people tested, and opportunities to increase knowledge of HIV transmission, prevention and care through provision of correct information to households. Community members also saw the intervention as increasing opportunities to engage and influence family members and to role model positive behaviours. Participants also perceived social risks and dangers associated with home-based testing including the potential for conflict, coercion, stigma, and psychological distress within households. Community members emphasised the need for individual and community preparation, including procedures to protect confidentiality, provisions for psychological and social support, and links to appropriate services for HIV-positive persons.

RESUMEN

A rapid assessment was undertaken with drug using commercial sex workers (CSWs) to investigate practices putting them at risk for contracting HIV. It included key informant (KI) (N = 67) and focus group (N = 10) interviews in locations with a high prevalence of drug use in Cape Town, Durban and Pretoria, South Africa. HIV testing of KIs was conducted. Cocaine, Ecstasy, heroin and methaqualone are used by CSWs prior to, during and after sex. Drugs enhance the sexual experience and prolong sex sessions. Interviews revealed inconsistent condom use among CSWs together with other risky sexual practices such as needle sharing. Among CSWs who agreed to HIV testing, 34% tested positive. Barriers to accessing drug treatment and HIV treatment and preventive services were identified. Interventions recognizing the role of drug abuse in HIV transmission should be prioritized, and issues of access to services, stigma and power relations must be considered.

RESUMEN

South Africa is experiencing significant changes in patterns of illicit drug use, including increasing injection and non-injection drug use, and the use of drugs by persons engaged in sex work, both of which could further expand the HIV/AIDS epidemic. In 2005, a rapid ethnographic assessment was conducted in Durban, South Africa, to learn more about patterns of drug use and HIV risk behaviors among drug-using, street-based sex workers. Field teams recruited 52 current injection and non-injection drug users for key informant interviews and focus groups, and they conducted mapping and observation in identified high-risk neighborhoods. Key informants were offered free, voluntary counseling and HIV rapid testing. The results of the assessment indicate that in this population, drugs play an organizing role in patterns of daily activities, with sex work closely linked to the buying, selling, and using of drugs. Participants reported using multiple drugs including crack cocaine, heroin, Ecstasy and Mandrax, and their choices were based on their expectations about the functional role and behavioral and pharmacological properties of the drugs. The organization of sex work and patterns of drug use differ by gender, with males exercising more control over daily routines and drug and sexual transactions than females. Activities of female sex workers are subject to considerable control by individual pimps, many of whom also function as landlords and drug dealers. A strong hold over the overlapping economies of drugs and sex work by a few individuals extends to control of the physical and social settings in which sex is exchanged and drugs are sold and used as well as the terms under which sex work is carried out. The potential for accelerated HIV spread is considerable given the evidence of overlapping drug-using and sexual risk behaviors and the mixing patterns across drug and sexual risk networks.

RESUMEN

The current assessment was undertaken to examine the link between drug use and sexual risk behavior among men who have sex with men (MSM) in locations known to have high prevalence rates of drug use and sexual risk behavior in Cape Town, Durban and Pretoria, South Africa. Street intercepts and purposive snowball sampling were used to recruit drug-using MSM. A rapid assessment was undertaken which included observation, mapping, key informant interviews and focus group interviews with MSM. Drug using key informants were tested for HIV. The use of drugs like crack cocaine, cannabis and methamphetamine to specifically facilitate sexual encounters was evident. Drugs led to inconsistent condom use and other high-risk sexual activities despite HIV risk knowledge being high. Many injecting drug-using MSM shared needles and reused equipment. Among MSM who agreed to HIV testing, one-third tested positive. Views about drug and HIV treatment and preventive services and their efficacy were mixed. Various barriers to accessing services were highlighted including homosexual stigmatization and availability of drugs in treatment facilities. Recommendations include addressing the gap between HIV-risk knowledge and practice, extending VCT services for MSM, increasing the visibility of drug abuse services within communities, addressing concerns about drug availability in treatment centers as well as reintegration issues and the need for after-care services, reducing stigmatization in drug and HIV services for MSM and finally, strengthening the link between drug treatment services and HIV prevention by integrating HIV/drug-related risks into HIV prevention efforts and HIV risks into drug use prevention efforts.

RESUMEN

Complex networks of protein-protein interactions are key determinants of cellular function, including those regulated by G-protein-coupled receptors (GPCRs). Formation of either stable or transitory complexes are involved in regulating all aspects of receptor function, from ligand binding through to signal transduction, desensitization, resensitization and downregulation. Today, 50% of all recently launched drugs are targeted against GPCRs. This particular class of proteins is extremely useful as a drug target because the receptors are partly located outside the cell, simplifying bioavailability and delivery of drugs directed against them. However, being located within the cell membrane causes difficulties for the study of GPCR function and bioluminescence resonance energy transfer (BRET), a naturally occurring phenomenon, represents a newly emerging, powerful tool with which to investigate and monitor dynamic interactions involving this receptor class. BRET is a noninvasive, highly sensitive technique, performed as a simple homogeneous assay. involving the proximity-dependent transfer of energy from an energy donor to acceptor resulting in the emission of light. This technology has several advantages over alternative approaches as the detection occurs within live cells, in real time, and is not restricted to a particular cellular compartment. The use of such biophysical techniques as BRET, will not only increase our understanding of the nature of GPCR regulation and the protein complexes involved, but could also potentially lead to the development of novel therapeutics that modulate these interactions.
