Sex Trafficking of Minors in the U.S.: Implications for Policy, Prevention and Research

Context: Information currently available on the trafficking of minors in the U.S. for commercial sexual exploitation includes approximations of the numbers involved, risk factors that increase the likelihood of victimization and methods of recruitment and control. However, specific characteristics about this vulnerable population remain largely unknown. Objective: This article has two distinct purposes. The first is to provide the reader with an overview of available information on minor sex trafficking in the U.S. The second is to present findings and discuss policy, research, and educational implications from secondary data analysis of 115 cases of minor sex trafficking in the U.S. Design: Minor sex trafficking cases were identified through two main venues - a review of U.S. Department of Justice press releases of human trafficking cases and an online search of media reports. Searches covered the time period from October 28, 2000, which coincided with the passage of the VTVPA through October 31, 2009. Cases were included in analysis if the incident involved at least one victim under the age of 18, occurred in the U.S., and at least one perpetrator had been arrested, indicted, or convicted. Results: A total of 115 separate incidents involving at least 153 victims were located. These occurrences involved 215 perpetrators, with the majority of them having been convicted (n = 117, 53.4%), The number of victims involved in a single incident ranged from 1 to 9. Over 90% of victims were female who ranged in age from 5 to 17 years. There were more U.S. minor victims than those from other countries. Victims had been in captivity from less than 6 months to 5 years. Minors most commonly fell into exploitation through some type of false promise indicated (16.3%, n = 25), followed by kidnapping (9.8%, n = 15). Over a fifth of the sample (22.2%, n = 34) were abused through two commercial sex practices, with almost all (94.1%, n = 144) used in prostitution. One of every five victims (24.8%, n = 38) had been advertised on an Internet website. Conclusions: Results of a review of known information about minor sex trafficking and findings from analysis of 115 incidents of the sex trafficking of youth in the U.S. indicate a need for stronger legislation to educate various professional groups, more comprehensive services for victims, stricter laws for pimps and traffickers, and preventive educational interventions beginning at a young age.

Aggressive vs. conservative phototherapy for infants with extremely low birth weight.

BACKGROUND: It is unclear whether aggressive phototherapy to prevent neurotoxic effects of bilirubin benefits or harms infants with extremely low birth weight (1000 g or less). METHODS: We randomly assigned 1974 infants with extremely low birth weight at 12 to 36 hours of age to undergo either aggressive or conservative phototherapy. The primary outcome was a composite of death or neurodevelopmental impairment determined for 91% of the infants by investigators who were unaware of the treatment assignments. RESULTS: Aggressive phototherapy, as compared with conservative phototherapy, significantly reduced the mean peak serum bilirubin level (7.0 vs. 9.8 mg per deciliter [120 vs. 168 micromol per liter], P<0.01) but not the rate of the primary outcome (52% vs. 55%; relative risk, 0.94; 95% confidence interval [CI], 0.87 to 1.02; P=0.15). Aggressive phototherapy did reduce rates of neurodevelopmental impairment (26%, vs. 30% for conservative phototherapy; relative risk, 0.86; 95% CI, 0.74 to 0.99). Rates of death in the aggressive-phototherapy and conservative-phototherapy groups were 24% and 23%, respectively (relative risk, 1.05; 95% CI, 0.90 to 1.22). In preplanned subgroup analyses, the rates of death were 13% with aggressive phototherapy and 14% with conservative phototherapy for infants with a birth weight of 751 to 1000 g and 39% and 34%, respectively (relative risk, 1.13; 95% CI, 0.96 to 1.34), for infants with a birth weight of 501 to 750 g. CONCLUSIONS: Aggressive phototherapy did not significantly reduce the rate of death or neurodevelopmental impairment. The rate of neurodevelopmental impairment alone was significantly reduced with aggressive phototherapy. This reduction may be offset by an increase in mortality among infants weighing 501 to 750 g at birth. (ClinicalTrials.gov number, NCT00114543.)

The effectiveness of a needleless intravenous system in prevention of percutaneous injury in two hospitals

This study assessed if hospital-wide implementation of a needleless intravenous connection system reduces the number of reported percutaneous injuries, overall and those specifically due to intravenous connection activities.^ Incidence rates were compared before and after hospital-wide implementation of a needleless intravenous system at two hospitals, a full service general hospital and a pediatric hospital. The years 1989-1991 were designated as pre-implementation and 1993 was designated as post-implementation. Data from 1992 were not included in the effectiveness evaluation to allow employees to become familiar with use of the new device. The two hospitals showed rate ratios of 1.37 (95% CI = 1.22-1.54, p $\le$.0001) and 1.63 (95% CI = 1.34-1.97, p $\le$.0001), or a 27.1% and a 38.6% reduction in overall injury rate, respectively. Rate ratios for intravenous connection injuries were 2.67 (95% CI = 1.89-3.78, p $\le$.0001) and 3.35 (95% CI = 1.87-6.02, p $\le$.0001), or a 62.5% and a 69.9% reduction in injury rate, respectively. Rate ratios for all non-intravenous connection injuries were calculated to control for factors other than device implementation that may have been operating to reduce the injury rate. These rate ratios were lower, 1.21 and 1.44, demonstrating the magnitude of injury reduction due to factors other than device implementation. It was concluded that the device was effective in reduction of numbers of reported percutaneous injuries.^ Use-effectiveness of the system was also assessed by a survey of randomly selected device users to determine satisfaction with the device, frequency of use and barriers to use. Four hundred seventy-eight surveys were returned for a response rate of 50.9%. Approximately 94% of respondents at both hospitals expressed satisfaction with the needleless system and recommended continued use. The survey also revealed that even though over 50% of respondents report using the device "always" or "most of the time" for intravenous medication administration, flushing lines, and connecting secondary intravenous lines, needles were still being used for these same activities. Compatibility, accessibility and other technical problems were reported as reasons for using needles for these activities. These problems must be addressed, by both manufacturers and users, before the needleless system will be effective in prevention of all intravenous connection injuries. ^

Effect of cancer chemotherapy on the frequency of minisatellite repeat number changes in human sperm

The objective of this study was to determine whether cancer chemotherapy induces detectable mutations in DNA of the human germline and whether minisatellite repeat number changes can be used as a sensitive indicator of genetic damage in human sperm caused by mutagens. We compared the mutation frequencies in sperm of the same cancer patients pre- and post-, pre- and during, or during and post-treatment. Small pool polymerase chain reaction (SP-PCR) (DNA equivalent to approximately 100 sperm) and Southern blotting techniques were used to detect mutations and quantify the frequency of repeat number changes at the minisatellite MS205 locus. One pre- and one post-treatment semen sample was obtained from each Hodgkin's disease patient treated with either: (1) a regimen without alkylating agents, Novantrone, Oncovin, Vinblastine, and Prednisone (NOVP), 4 patients; (2) a regimen containing alkylating agents, Cytoxan, Vinblastine, Procarbazine, and Prednisone (CVPP)/Adriamycin, Bleomycin, DTIC, CCNU, and Prednisone (ABDIC), 2 patients; and (3) a regimen containing alkylating agents, Mechlorethamine, Oncovin, Procarbazine, and Prednisone (MOPP), 1 patient. One pre- and one during treatment semen sample from each of two Hodgkin's disease patients treated with Adriamycin, Bleomycin, Vinblastine, and Dacarbazine (ABVD) were obtained. One during and one post-treatment semen sample from a Hodgkin's disease patient treated with NOVP were also obtained. At least 7900 sperm in each sample were screened for the repeat number changes at the MS205 locus by multi-aliquots of SP-PCR. The mutation frequencies of pre- and post-treatment for the four patients treated with NOVP were 0.22 and 0.18%; 0.24 and 0.16%; 0.35 and 0.28%; and 0.19 and 0.18%. With CVPP/ABDIC, they were 0.22 and 0.23%; and 0.94 and 0.98% for the two patients and with MOPP they were 0.79 and 1.14%. The mutation frequencies of pre- and during treatment with ABVD were 0.09 and 0.07%; and 0.34 and 0.27% for the two patients. The mutation frequencies of during and post-treatment with NOVP for one patient were 0.31 and 0.25%. A statistically significant increase in mutation frequency was only found in the patient treated with MOPP. According to the time of samples collected after or during treatment and the above results, we conclude that there is no effect of NOVP and CVPP/ABDIC regimens on the mutation frequency in spermatogonia. The spermatocytes are not highly sensitive to chemotherapy agents compared to spermatogonia at the minisatellite MS205 locus. MOPP treatment may increase the mutation frequency at the MS205 locus in spermatogonia. ^
