Empowering Medical Professionals to Help Victims of Trafficking

Purpose: to provide commentary of two review articles that discuss the role of medical professionals in combating human trafficking: “Health Care Providers' Training Needs Related to Human Trafficking: Maximizing the Opportunity to Effectively Screen and Intervene” by Isaac, Solak, and Giardino, and “Human Trafficking: What is the Role of the Health Care Provider?” by Crane and Moreno. Findings: Both articles provide a good introduction and explanation of the psychosocial and medical issues faced by many trafficking victims; however, they succeed only to varying degrees in describing all the gaps in the medical system and the vital next steps forward. Conclusion: The key next steps in the fight against human trafficking include: multidisciplinary teams need to improve coordination on all forms of human maltreatment; schools for all medical professions and social work need to significantly strengthen their curriculum on diagnosing and treating human maltreatment; and groups that provide training on human trafficking should partner with other agencies and organizations that provide training on child maltreatment and domestic violence.

Health Care Providers' Training Needs Related to Human Trafficking: Maximizing the Opportunity to Effectively Screen and Intervene

Human trafficking is a complex and multifaceted problem that takes the form of economic, physical and sexual exploitation of people, both adults and children, who are reduced to simple products for commerce. Human trafficking in the United States also has both a domestic and an international aspect. Health care providers are in a unique position to screen for victims of trafficking and may provide important medical and psychological care for victims while in captivity and thereafter. Trafficked persons are likely to suffer a wide spectrum of health risks that reflect the unique circumstances and experiences in a trafficked victim’s life. Although trafficked victims typically have experienced inadequate medical care, once contact is made by the victim with the health care professionals, the opportunity then exists to identify, treat, and assist such victims. The range of services and supports required to appropriately respond to human trafficking victims once identified is broad and typically goes beyond just what is immediately provided by the health care professional and includes safe housing, legal advice, income support, and, for international victims, immigration status related issues. An informed and responsive community is necessary to serve both the international and domestic victims of human trafficking, and needs assessments demonstrated a number of barriers that hindered the delivery of effective services to human trafficking victims. One of the consistent needs identified to combat these barriers was enhanced training among all professionals who might come in contact with human trafficking victims. We highlight the efforts of the Houston Rescue and Restore Coalition (HRRC), a local grassroots non-profit organization whose mission focuses on raising awareness of human trafficking in the Greater Houston Metropolitan area. HRRC responded to the consistent recommendation from various community needs assessments for additional training of front line professionals who would have the opportunity to identify human trafficking victims and supported the design and pilot testing of a health professions training program around human trafficking. Dissemination of this type of training along with careful evaluation and continued refinement will be one way for health care professionals to engage in a positive manner with human trafficking victims.

Evaluation of oxidative damage and renal distal tubule cell stress response following exposure to lindane

Lindane, or γ-hexachlorocyclohexane, is a chlorinated hydrocarbon pesticide that was banned from U.S. production in 1976, but until recently continued to be imported and applied for occupational and domestic purposes. Lindane is known to cause central nervous system (CNS), immune, cardiovascular, reproductive, liver, and kidney toxicity. The mechanism for which lindane interacts with the CNS has been elucidated, and involves antagonism of the γ-aminobutyric acid/benzodiazepine (GABAA/BZD) receptor. Antagonism of this receptor results in the inhibition of Cl- channel flux, with subsequent convulsions, seizures, and paralysis. This response makes lindane a desirable defense against arthropod pests in agriculture and the home. However, formulation and application of this compound can contribute to human toxicity. In conjunction with this exposure scenario, workers may be subject to both heat and physical stress that may increase their susceptibility to pesticide toxicity by altering their cellular stress response. The kidneys are responsible for maintaining osmotic homeostasis, and are exposed to agents that undergo urinary excretion. The mechanistic action of lindane on the kidneys is not well understood. Lindane, in other organ systems, has been shown to cause cellular damage by generation of free radicals and oxidative stress. Previous research in our laboratory has shown that lindane causes apoptosis in distal tubule cells, and delays renal stress response under hypertonic stress. Characterizing the mechanism of action of lindane under conditions of physiologic stress is necessary to understand the potential hazard cyclodiene pesticides and other organochlorine compounds pose to exposed individuals under baseline conditions, as well as under conditions of physiologic stress. We demonstrated that exposure to lindane results in oxidative damage and dysregulation of glutathione response in renal distal tubule (MDCK) cells. We showed that under conditions of hypertonic stress, lindane-induced oxidative stress resulted in early onset apoptosis and corresponding down-regulated expression of the anti-apoptotic protein, Bcl-xL. Thus, the interaction of lindane with renal peripheral benzodiazepine receptors (PBR) is associated with attenuation of cellular protective proteins, making the cell more susceptible to injury or death. ^

CHARACTERIZATION OF THE COLONIZATION FACTOR ANTIGEN II PLASMID (CFA/II) FROM ENTEROTOXIGENIC ESCHERICHIA COLI

The etiological role of enterotoxigenic E. coli (ETEC) in diarrheal diseases of man and domestic animals is firmly established. Besides the production of enterotoxins (ST and LT), ETEC produces other important virulence factors; the colonization factor antigens (CFAs). CFAs mediate the attachment of ETEC to the epithelial cells of the small intestine, and this favors colonization by the bacteria and facilitates delivery of the enterotoxins to the intestinal cells.^ The production of enterotoxin and CFA is determined by plasmids and has been found to be restricted to a select number of E. coli serotypes.^ In this work, plasmid DNA analysis was performed in twenty-three CFA/II-producing enterotoxigenic Escherichia coli strains and their spontaneous CFA/II-negative derivatives. In some cases, strains lost the high molecular weight plasmid and also the ability to produce CFA/II, ST and LT. In other cases there was a deletion of the plasmid, which produced strains that were CFA/II('-), ST('-), LT('-) or CFA/II('-), ST('+), LT('+).^ The CFA/II plasmid from strain PB-176 (06:H16:CFA/II('+), ST('+), LT('+)) was transferred by transformation into E. coli K12 with concomitant transfer of the three characteristics: CFA/II, ST and LT.^ A physical map of the prototype CFA/II:ST:LT (pMEP60) plasmid was constructed by restriction endonuclease analysis and compared to plasmids from three other CFA/II-producing strains. A CFA/II-negative (but ST and LT positive) deletion derivative of pMEP60 (pMEP30) was also included in the map. The four CFA/II plasmids analyzed had a common region of approximately 30 kilobase pairs. The toxin genes were approximately 5 kbp apart and about 20 kbp from the common region. The information given by this physical map could be of great value when constructing a clone that will express the CFA/II genes but not the toxin genes. ^

Assessing residents' readiness to screen for domestic violence: Utilizing the transtheoretical model - stages of change, decisional balance and self-efficacy

Domestic violence is a major public health problem, yet most physicians do not effectively identify patients at risk. Medical students and residents are not routinely educated on this topic and little is known about the factors that influence their decisions to include screening for domestic violence in their subsequent practice. In order to assess the readiness of primary care residents to screen all patients for domestic violence, this study utilized a survey incorporating constructs from the Transtheoretical Model, including Stages of Change, Decisional Balance (Pros and Cons) and Self-Efficacy. The survey was distributed to residents at the University of Texas Health Science Center Medical School in Houston in: Internal Medicine, Medicine/Pediatrics, Pediatrics, Family Medicine, and Obstetrics and Gynecology. Data from the survey was analyzed to test the hypothesis that residents in the earlier Stages of Change report more costs and fewer benefits with regards to screening for domestic violence, and that those in the later stages exhibit higher Self-Efficacy scores. The findings from this study were consistent with the model in that benefits to screening (Pros) and Self-Efficacy were correlated with later Stages of Change, however reporting fewer costs (Cons) was not. Very few residents were ready to screen all of their patients.^

An evaluation of the Cypress Creek watershed for inorganic chemical load as it flows into Lake Houston

Background. The Cypress Creek is one of the main tributaries of Lake Houston, which provides drinking water to 21.4 million customers. Furthermore, the watershed is being utilized for contact and non-contact recreation, such as canoeing, swimming, hiking trail, and picnics. Water along the creek is impacted by numerous wastewater outfalls from both point and non-point sources. As the creek flows into Lake Houston, it carries both organic and inorganic contaminants that may affect the drinking water quality of this important water source reservoir. Objective. This study was carried out to evaluate the inorganic chemical load of the water in Cypress Creek along its entire length, from the headwaters in Waller County and up to the drainage into Lake Houston. The purpose was to determine whether there are hazardous concentrations of metals in the water and what would be the likely sources. Method. Samples were collected at 29 sites along the creek and analyzed for 29 metals, 17 of which were on the Environmental Protection Agency priority pollution list. Public access sites primarily at bridges were used for sample collection. Samples were transported on ice to the University Of Texas School Of Public Health laboratory, spiked with 2 ml HNO3 kept overnight in the refrigerator, and the following day transported to the EPA laboratory for analysis. Analysis was done by EPA Method 200.7-ICP, Method 200.8ICP/MS and Method 245.1-CVAAS. Results. Metals were present above the detection limits at 65% of sites. Concentrations of aluminum, iron, sodium, potassium, magnesium, and calcium, were particularly high at all sites. Aluminum, sodium, and iron concentrations greatly exceeded the EPA secondary drinking water standards at all sites. ^ Conclusion. The recreational water along Cypress Creek is impacted by wastewater from both permitted and non-permitted outfalls, which deposit inorganic substances into the water. Although a number of inorganic contaminants were present in the water, toxic metals regulated by the EPA were mostly below the recommended limits. However, high concentrations of aluminum, sodium, and iron in the Cypress Creek bring forward the issue of unauthorized discharges of salt water from mining, as well as industrial and domestic wastewater.^

Domestic Violence Resources for Women Receiving Intensive Family Preservation Services

Intimate partner violence is a common correlate of child abuse and neglect and often is not addressed in family preservation services. In many cases, the ideologies of family preservationists and advocates for women 's safety can be at odds. This article presents a study of a collaborative model of intervention, utilizing family preservation workers and community resource practitioners working with domestic violence as group facilitators. The study utilizes a pretest, post-test design to evaluate a domestic violence resource group for women who were concurrently receiving intensive family preservation services. The study examines the effect of the program on participants' self-perceptions regarding self-esteem, independence, goals, social isolation, and assertiveness. Caseworker perceptions of client characteristics also are evaluated, and qualitative responses of the effects of the program are included.
