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.

THE TRANSLATION PRODUCTS OF MOLONEY MURINE SARCOMA VIRUS 124 GENOMIC RNA

Murine sarcoma viruses constitute a class of replication-defective retroviruses. Cellular transformation may be induced by these viruses in vitro; whereas, fibrosarcomas may result in animals infected with them in vivo (Tooze, 1973; Bishop, 1978). Hybridization studies suggest that murine sarcoma viruses arose by recombination between nondefective murine leukemia virus sequences and certain cellular sequences present in uninfected mouse cells (Hu et al., 1977). A specific gene product, however, has not been implicated in murine sarcoma virus transformation.^ One line of murine sarcoma virus-producing cells, Mo-MuSV-clone 124, (Ball et al., 1973), was studied biochemically because it mainly produces the sarcoma virus as a pseudotype packaged with helper murine leukemia virus proteins. The sarcoma viral RNA was translated in a sophisticated cell-free protein synthesizing system (Murphy and Arlinghaus, 1978). The translation products were analyzed by a number of techniques, including electrophoresis in denaturing gels of SDS polyacrylamide, immunoprecipitation, and peptide mapping. The major products of the total RNA purified from the virus preparation were shown to have molecular weights of about 63,000 (P63('gag)), 42,000 (P42), 40,000 (P40), 38,000 (P38), and 23,000 (P23). The size class of mRNA coding for each of the cell-free products was estimated using a poly(A) selection technique and sucrose gradient fractionation. These analyses were used to localize the coding information related to each of the in vitro synthesized cell-free products within the sarcoma virus genome.^ The major findings of these studies were: (1) the 5' half of the sarcoma viral RNA codes for the 63,000 dalton polypeptide and 42,000 - 38,000 dalton polypeptides derived from the "gag" gene; and (2) the 3' half of the sarcoma viral RNA codes for a 38,000 dalton polypeptide and possibly derived from the cellular acquired sequences. ^

CHARACTERIZATION AND COMPARISON OF SUBHUMAN PRIMATE AND HUMAN TYPE C RETROVIRAL GENE PRODUCTS

The viral specific precursor polyproteins of simian sarcoma/simian associated virus (SiSV/SiAV), baboon endogenous viruses (BaEV), and three human isolate retroviruses, have been analyzed by radioimmunoprecipitation and tryptic peptide mapping. Cells infected with the BaEV isolates are characterized by identical precursor polyproteins: gPr80-85('env), Pr70-71('gag), and Pr65-67('gag). By tryptic digest mapping, m7-BaEV and 455K-BaEV were shown to be highly related. By comparison, mapping studies showed that BILN-BaEV was less highly related to m7-BaEV than was 455K-BaEV. Chase-incubated cells infected with BaEV also contained a stable, p28-related polyprotein termed P72('gag). This polyprotein appeared to arise by posttranslational modification of Pr70-71('gag). Tryptic digest mapping of BaEV and HL23V precursor polyproteins suggested that the BaEV-like component of HL23V was more closely related to m7-BaEV than to 455K-BaEV or BILN-BaEV.^ The intracellular precursor polyproteins of SiSV(SiAV) and gibbon ape leukemia virus (GaLV) were compared to the intracellular proteins of the human retrovirus isolates, HL23V, HEL12V, and A1476V. Cells infected with SiSV(SiAV) were characterized by polyproteins Pr200('gag-pol), gPr80('env), Pr80('gag), pr60('gag), and Pr40('gag). We have found that the human isolates are identical to true SiAV with regard to the size and structure of their precursor polyproteins. Both gPr80('env) and Pr60('gag) of SiAV were identical by tryptic peptide mapping to the respective proteins from the three human retroviral isolates examined. We have also shown that these viruses differ significantly from each of the GaLV isolates studied. Since SiAV differs substantially from any known GaLV isolate, we feel that it is unlikely that SiAV is a subtype of GaLV which exists today in the gibbon gene pool. The experimental evidence suggests that SiAV may be an exogenous human retrovirus that was transmitted originally into the human gene pool in the distant past by cross-species infection with GaLV(,SF) or with the GaLV(,SF) progenitor virus. It is, therefore, quite possible that SiAV expression in the pet woolly monkey arose from a recent infection of that monkey with SiAV from humans.^

Tobacco use and related psychosocial risk factors among youth in urban India: Assessment of Project MYTRI follow-up surveys

Project MYTRI (Mobilizing Youth for Tobacco-Related Initiatives in India) was a large 2-year randomized school-based trial with a goal to reduce and prevent tobacco use among students in 6th and 8th grades in Delhi and Chennai in India (n=32 schools). Baseline analyses in 2004 showed that 6th grade students reported more tobacco use than 8 th grade students, opposite of what is typically observed in developed countries like the US. The present study aims to study differences in tobacco use and psychosocial risk factors between the 6th grade cohort and 8th grade cohort, in a compliant sub-sample of control students that were present at all 3 surveys from 2004-06. Both in 2004 and 2005, 6th grade cohort reported significantly greater prevalence of ever use of all tobacco products (cigarettes, bidis, chewing tobacco, any tobacco). These significant differences in ever use of any tobacco between cohorts were maintained by gender, city and socioeconomic status. The 6th grade cohort also reported significantly greater prevalence of current use of tobacco products (cigarettes, chewing tobacco, any tobacco) in 2004. Similar findings were observed for psychosocial risk factors for tobacco use, where the 6th grade cohort scored higher risk than 8th grade cohort on scales for intentions to smoke or chew tobacco and susceptibility to smoke or chew tobacco in 2004 and 2005, and for knowledge of health effects of tobacco in all three years.^ The evidence of early initiation of tobacco use in our 6th grade cohort in India indicates the need to target prevention programs and other tobacco control measures from a younger age in this setting. With increasing proportions of total deaths and lost DALYs in India being attributable to chronic diseases, addressing tobacco use among younger cohorts is even more critical. Increase in tobacco use among youth is a cause for concern with respect to future burden of chronic disease and tobacco-related mortality in many developing countries. Similarly, epidemiological studies that aim to predict future death and disease burden due to tobacco should address the early age at initiation and increasing prevalence rates among younger populations. ^

A critical review: Why isn't "cold pasteurization" being used widespread as a method to prevent food-related illnesses as a result of the consumption of ready-to-eat, fresh fruits, and vegetables

The Centers for Disease Control estimates that foodborne diseases cause approximately 76 million illnesses, 325,000 hospitalizations, and 5,000 deaths in the United States each year. The American public is becoming more health conscious and there has been an increase in the dietary intake of fresh fruits and vegetables. Affluence and demand for convenience has allowed consumers to opt for pre-processed packaged fresh fruits and vegetables. These pre-processed foods are considered Ready-to-Eat. They have many of the advantages of fresh produce without the inconvenience of processing at home. After seeing a decline in food-related illnesses between 1996 and 2004, due to an improvement in meat and poultry safety, tainted produce has tilted the numbers back. This has resulted in none of the Healthy People 2010 targets for food-related illness reduction being reached. Irradiation has been shown to be effective in eliminating many of the foodborne pathogens. The application of irradiation as a food safety treatment has been widely endorsed by many of the major associations involved with food safety and public health. Despite these endorsements there has been very little use of this technology to date for reducing the disease burden associated with the consumption of these products. A review of the available literature since the passage of the 1996 Food Quality Protection Act was conducted on the barriers to implementing irradiation as a food safety process for fresh fruits and vegetables. The impediments to adopting widespread utilization of irradiation food processing as a food safety measure involve a complex array of legislative, regulatory, industry, and consumer issues. The FDA’s approval process limits the expansion of the list of foods approved for the application of irradiation as a food safety process. There is also a lack of capacity within the industry to meet the needs of a geographically dispersed industry.^
