RESUMO

OBJECTIVES: Recently, several state indoor tanning laws, including age restrictions, were promulgated to reduce indoor tanning among minors. We examined the effects of these laws on adolescent indoor tanning. METHODS: We used nationally representative data from the 2009 and 2011 national Youth Risk Behavior Surveys (n = 31 835). Using multivariable logistic regression, we examined the association between state indoor tanning laws and indoor tanning among US high school students. RESULTS: Female students in states with indoor tanning laws were less likely to engage in indoor tanning than those in states without any laws. We observed a stronger association among female students in states with systems access, parental permission, and age restriction laws than among those in states without any laws. We found no significant association among female students in states with only systems access and parental permission laws or among male students. CONCLUSIONS: Indoor tanning laws, particularly those including age restrictions, may be effective in reducing indoor tanning among female high school students, for whom rates are the highest. Such reductions have the potential to reduce the health and economic burden of skin cancer.

RESUMO

Our objective was to assess the sensitivity and specificity of human papillomavirus (HPV) testing for cervical cancer screening in randomized trials. We conducted a systematic literature search of the following databases: MEDLINE, CINAHL, EMBASE, and Cochrane. Eligible studies were randomized trials comparing HPV-based to cytology-based screening strategies, with disease status determined by colposcopy/biopsy for participants with positive results. Disease rates (cervical intraepithelial neoplasia [CIN]2 or greater and CIN3 or greater), sensitivity, and positive predictive value were abstracted or calculated from the articles. Six studies met inclusion criteria. Relative sensitivities for detecting CIN3 or greater of HPV testing-based strategies vs cytology ranged from 0.8 to 2.1. The main limitation of our study was that testing methodologies and screening/management protocols were highly variable across studies. Screening strategies in which a single initial HPV-positive test led to colposcopy were more sensitive than cytology but resulted in higher colposcopy rates. These results have implications for cotesting with HPV and cytology as recommended in the United States.

RESUMO

BACKGROUND: The burden of global injury-related deaths predominantly affects developing countries, which have little infrastructure to evaluate these disparities. We describe injury-related mortality patterns in Kampala, Uganda and compare them with data from the United States and San Francisco (SF), California. METHODS: We created a database in Kampala of deaths recorded by the City Mortuary, the Mulago Hospital Mortuary, and the Uganda Ministry of Health from July to December 2007. We analyzed the rate and odds ratios and compared them to data from the U.S. Centers for Disease Control and Prevention and the California Department of Public Health. RESULTS: In Kampala, 25% of all deaths were due to injuries (812/3303) versus 6% in SF and 7% in the United States. The odds of dying of injury in Kampala were 5.0 times higher than in SF and 4.2 times higher than in the United States. Age-standardized death rates indicate a 93% greater risk of dying from injury in Kampala than in SF. The mean age was lower in Kampala than in SF (29 vs. 44 years). The adult injury death rate (rate ratio, or RR) was higher in Kampala than in SF (2.3) or the United States (1.5). Head/neck injury was reported in 65% of injury deaths in Kampala compared to 34% in SF [odds ratio (OR) 3.7] and 28% in the US (OR 4.8). CONCLUSIONS: Urban injury-related mortality is significantly higher in Uganda than in the United States. Injury preferentially affects adults in the prime of their economically productive years. These findings serve as a call for stronger injury prevention and control policies in Uganda.

RESUMO

BACKGROUND: Uganda currently has no organized prehospital emergency system. We sought to measure the current burden of injury seen by lay people in Kampala, Uganda and to determine the feasibility of a lay first-responder training program. METHODS: We conducted a cross-sectional survey of current prehospital care providers in Kampala: police officers, minibus taxi drivers, and Local Council officials, and collected data on types and frequencies of emergencies witnessed, barriers to aid provision, history of training, and current availability of first-aid supplies. A context-appropriate course on basic first-aid for trauma was designed and implemented. We measured changes in trainees' fund of knowledge before and after training. RESULTS: A total of 309 lay people participated in the study, and during the previous 6 months saw 18 traumatic emergencies each; 39% saw an injury-related death. The most common injury mechanisms were road crashes, assault, and burns. In these cases, 90% of trainees provided some aid, most commonly lifting (82%) or transport (76%). Fifty-two percent of trainees had previous first-aid training, 44% had some access to equipment, and 32% had ever purchased a first-aid kit. Before training, participants answered 45% of test questions correctly (mean %) and this increased to 86% after training (p < 0.0001). CONCLUSIONS: Lay people witness many emergencies and deaths in Kampala, Uganda and provide much needed care but are ill-prepared to do so. A context-appropriate prehospital trauma care course can be developed and improve lay people's knowledge of basic trauma care. The effectiveness of such a training program needs to be evaluated prospectively.

RESUMO

PURPOSE: To examine trends in sunscreen use during 1999-2009 among U.S. high school students. METHODS: Data from the 1999-2009 national Youth Risk Behavior Surveys were analyzed. The surveys used a three-stage cluster sample design to produce nationally representative samples of students in grades 9-12 attending public and private schools. Student participation in the survey was anonymous and voluntary. Participants completed a self-administered questionnaire during a regular class period. The overall response rates ranged from 63% to 72%. RESULTS: During 1999-2009, the percentage of white students who never or rarely wore sunscreen when outside on a sunny day for >1 hour increased (from 57.5% to 69.4%), as did the percentage among Hispanic students (from 71.6% to 77.9%). This increase was most pronounced among white female students. The percentage of white and Hispanic students who most of the time or always wore sunscreen decreased during this same period. Rates of sunscreen use did not change among black students. CONCLUSIONS: Because of declines in sunscreen use, professionals in clinical, school, and community settings should emphasize the important role sunscreen may play in preventing skin cancer.

RESUMO

PURPOSE: Indoor tanning is a risk factor for developing melanoma. Although in 2009, 6.7% of male high school students reported using an indoor tanning device, compared with 25.4% of female students (Eaton DK, Kann L, Kinchen S, et al, MMWR Surveill Summ 2010;59:1-142), it is also less well characterized in male than in female adolescents. METHODS: The associations between appearance-related and other health-related behaviors with indoor tanning device use were examined among male high school students in the United States, using the 2009 National Youth Risk Behavior Survey. RESULTS: Adjusted analysis of cross-sectional data showed that indoor tanning device use was positively associated with ever having taken steroids without a doctor's prescription, unhealthy weight control practices, binge drinking, eating fruits and vegetables five or more times per day, playing on at least one sports team, and attempted suicide. CONCLUSIONS: Understanding the relationship between indoor tanning device use and appearance-related and other health-related behaviors is useful in designing risk reduction interventions for skin cancer prevention.

RESUMO

BACKGROUND: We previously showed that in the absence of a formal emergency system, lay people face a heavy burden of injuries in Kampala, Uganda, and we demonstrated the feasibility of a basic prehospital trauma course for lay people. This study tests the effectiveness of this course and estimates the costs and cost-effectiveness of scaling up this training. METHODS AND FINDINGS: For six months, we prospectively followed 307 trainees (police, taxi drivers, and community leaders) who completed a one-day basic prehospital trauma care program in 2008. Cross-sectional surveys and fund of knowledge tests were used to measure their frequency of skill and supply use, reasons for not providing aid, perceived utility of the course and kit, confidence in using skills, and knowledge of first-aid. We then estimated the cost-effectiveness of scaling up the program. At six months, 188 (62%) of the trainees were followed up. Their knowledge retention remained high or increased. The mean correct score on a basic fund of knowledge test was 92%, up from 86% after initial training (n = 146 pairs, p = 0.0016). 97% of participants had used at least one skill from the course: most commonly haemorrhage control, recovery position and lifting/moving and 96% had used at least one first-aid item. Lack of knowledge was less of a barrier and trainees were significantly more confident in providing first-aid. Based on cost estimates from the World Health Organization, local injury data, and modelling from previous studies, the projected cost of scaling up this program was $0.12 per capita or $25-75 per life year saved. Key limitations of the study include small sample size, possible reporter bias, preliminary local validation of study instruments, and an indirect estimate of mortality reduction. CONCLUSIONS: Lay first-responders effectively retained knowledge on prehospital trauma care and confidently used their first-aid skills and supplies for at least six months. The costs of scaling up this intervention to cover Kampala are very modest. This may be a cost-effective first step toward developing formal emergency services in Uganda other resource-constrained settings. Further research is needed in this critical area of trauma care in low-income countries.

RESUMO

We examined the hypothesis that the introduction of an inflammatory agent would augment status epilepticus (SE)-induced neuronal injury in the developing rat brain in the absence of an increase in body temperature. Postnatal day 7 (P7) and P14 rat pups were injected with an exogenous provocative agent of inflammation, lipopolysaccharide (LPS), 2 h prior to limbic SE induced by either lithium-pilocarpine (LiPC) or kainic acid. Core temperature was recorded during the SE and neuronal injury was assessed 24 h later using profile cell counts in defined areas of the hippocampus. While LPS by itself did not produce any discernible cell injury at either age, it exacerbated hippocampal damage induced by seizures. In the LiPC model, this effect was highly selective for the CA1 subfield, and there was no concomitant rise in body temperature. Our findings show that inflammation increases the vulnerability of immature hippocampus to seizure-induced neuronal injury and suggest that inflammation might be an important factor aggravating the long-term outcomes of seizures occurring early in life.
