This analysis was conducted to evaluate the prevalence of airway obstruction among Latino poultry processing workers. Data were collected from 279 poultry processing workers and 222 other manual laborers via spirometry and interviewer-administered questionnaires. Participants employed in poultry processing reported the activities they perform at work. Participants with forced expiratory volume in 1 second (FEV1) or FEV1/forced expiratory volume (FVC) below the lower limits of normal were categorized as having airway obstruction. Airway obstruction was identified in 13% of poultry processing workers and 12% of the comparison population. Among poultry processing workers, the highest prevalence of airway obstruction (21%) occurred among workers deboning chickens (prevalence ratio: 1.75; 95% confidence interval: 0.97, 3.15). These findings identify variations in the prevalence of airway obstruction across categories of work activities.

Background: Immigrant Latino workers represent an expanding workforce in rural areas of the USA, where their employment is concentrated in occupations such as poultry processing that entail chemical, infectious, and mechanical skin exposures. Occupation-related skin illnesses in this vulnerable population are not well characterized., Objectives: This study was designed to describe the prevalences of skin diseases among immigrant Latino poultry processors and other manual workers in North Carolina., Methods: Community-based sampling was used to recruit 742 immigrant Latino workers, 518 of whom underwent a physical examination supervised by a board-certified dermatologist. The presence or absence of skin disease on the face, neck, arms, hands, and feet was recorded., Results: Workers ranged in age from 18 years to 68 years. Slightly over half of the sample were male (52.6%). Poultry workers represented 55.8% of the study sample. Infectious skin diseases were the most common diagnosis, present in 52.3% of workers. Inflammatory skin diseases were present in 28.2% and pigmentary disorders in 21.8% of workers. The most common skin conditions were tinea pedis (37.6%), onychomycosis (31.9%), scars (13.7%), acne (11.8%), and melasma (9.3%). Age, sex, first language, and work as a poultry processor accounted in part for the prevalence of these diseases., Conclusions: Several skin diseases are highly prevalent in immigrant Latino workers and may relate to work environment. These may impair the quality of life of these workers and predispose them to further illness., (© 2013 The International Society of Dermatology.)

Introduction: The prevalence of bifid median nerves and persistent median arteries, their co-occurrence, and their relationship to carpal tunnel syndrome (CTS) are only understood partially., Methods: We screened 1026 wrists of 513 Latino manual laborers in North Carolina for bifid median nerves and persistent median arteries using electrodiagnosis and ultrasound., Results: A total of 8.6% of wrists had a bifid median nerve, and 3.7% of wrists had a persistent median artery independent of subgroup ethnicity, age, gender, or type of work. An association with definite carpal tunnel syndrome was not found. The presence of either anatomic variant was associated with a high likelihood of co-occurrence of another variant in the same or the contralateral wrist., Conclusions: The occurrence of median anatomic variants can be determined in field studies using ultrasound. Persistent median arteries and bifid median nerves tend to co-occur but do not put manual laborers at additional risk of developing CTS., (Copyright © 2013 Wiley Periodicals, Inc.)

Introduction: Manual laborers are at increased risk for carpal tunnel syndrome (CTS), and a combination of history, physical examination, and nerve conduction studies is often used to screen for CTS in this population. Neuromuscular ultrasound may be a better screening tool, because it is painless. In this study we compare the accuracy of nerve conduction studies and ultrasound for CTS screening., Methods: Five hundred thirteen manual laborers were screened prospectively for CTS using nerve conduction studies and neuromuscular ultrasound, and the accuracy of the 2 techniques was compared using the Katz hand diagram as the diagnostic standard., Results: The ROC curves for the 2 techniques were not significantly different (P = 0.542), indicating that the approaches had similar diagnostic accuracy., Conclusions: Neuromuscular ultrasound is a painless technique that has diagnostic accuracy similar to nerve conduction studies and can be used to screen large populations at risk for CTS., (Copyright © 2012 Wiley Periodicals, Inc.)

Background: Use of prescription stimulants used to treat Attention Deficit/Hyperactivity Disorder (ADHD) for reasons other than prescribed, known as non-medical use, is a growing problem among undergraduates. Previous studies show that non-medical prescription stimulant (NMPS) users consume more alcohol than individuals who do not use NMPS. However, research on simultaneous use of NMPS and alcohol is limited. The objectives of this study were to: (1) determine the prevalence of simultaneous use of alcohol and NMPS; (2) examine predictors and consequences of simultaneous NMPS and alcohol use among undergraduates., Methods: In fall 2009, 4090 students from eight North Carolina universities completed a web-based survey., Results: Past year prevalence of NMPS use among this sample was 10.6% and simultaneous use of NMPS with alcohol was 4.9%. Among NMPS users, 46.4% used NMPS simultaneously with alcohol within the past year. Multivariable analysis revealed that simultaneous NMPS and alcohol use was associated with low grade point averages, use of other substances, and increased alcohol-related consequences. Simultaneous NMPS and alcohol users reported experiencing significantly more negative consequences than either past year drinkers who did not use prescription stimulants and concurrent NMPS and alcohol users (use over the past year but not at the same time)., Conclusions: Simultaneous use of NMPS and alcohol is high among NMPS users in our sample of undergraduate students. Simultaneous users are at increased risk of experiencing negative consequences. Thus, prevention and intervention efforts should include a focus on simultaneous NMPS and alcohol use., (Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.)

Background: The goal of this study is to improve understanding of immigrant Latino manual workers' occupational health, focusing on upper body musculoskeletal injury., Methods: Physical exams were conducted with a representative sample of 516 Latino poultry workers and manual laborers in western North Carolina; outcome measures were prevalence of epicondylitis, rotator cuff syndrome, and low back pain., Results: Low back pain (n = 89; 17.2%) and rotator cuff syndrome (n = 76; 14.7%) indicated by physical exam was common. Epicondylitis was less common, but still frequent (n = 30; 5.8%). Prevalence of each outcome did not differ between poultry processing workers and other manual workers. Workers >40 years old had greater incidence of rotator cuff syndrome and epicondylitis., Conclusions: Epicondylitis, rotator cuff syndrome, and low back pain are common in immigrant Latino workers, and may negatively impact long-term health and contribute to occupational health disparities., (Copyright © 2012 Wiley Periodicals, Inc.)

Background: High-risk drinking by college students continues to pose a significant threat to public health. Despite increasing evidence of the contribution of community-level and campus-level environmental factors to high-risk drinking, there have been few rigorous tests of interventions that focus on changing these interlinked environments. The Study to Prevent Alcohol Related Consequences (SPARC) assessed the efficacy of a comprehensive intervention using a community organizing approach to implement environmental strategies in and around college campuses. The goal of SPARC was to reduce high-risk drinking and alcohol-related consequences among college students., Methods: Ten universities in North Carolina were randomized to an Intervention or Comparison condition. Each Intervention school was assigned a campus/community organizer. The organizer worked to form a campus-community coalition, which developed and implemented a strategic plan to use environmental strategies to reduce high-risk drinking and its consequences. The intervention was implemented over a period of 3 years. Primary outcome measures were assessed using a web-based survey of students. Measures of high-risk drinking included number of days alcohol was consumed, number of days of binge drinking, and greatest number of drinks consumed (all in the past 30 days); and number of days one gets drunk in a typical week. Measures of alcohol-related consequences included indices of moderate consequences due to one's own drinking, severe consequences due to one's own drinking, interpersonal consequences due to others' drinking, and community consequences due to others' drinking (all using a past 30-day time frame). Measure of alcohol-related injuries included (i) experiencing alcohol-related injuries and (ii) alcohol-related injuries caused to others., Results: We found significant decreases in the Intervention group compared with the Comparison group in severe consequences due to students' own drinking and alcohol-related injuries caused to others. In secondary analyses, higher levels of implementation of the intervention were associated with reductions in interpersonal consequences due to others' drinking and alcohol-related injuries caused to others., Conclusions: A community organizing approach promoting implementation of environmental interventions can significantly affect high-risk drinking and its consequences among college students., (Copyright © 2012 by the Research Society on Alcoholism.)

Objective: To determine the prevalence of carpal tunnel syndrome (CTS) in Latino poultry-processing workers., Methods: Symptoms and nerve conduction studies were used to prospectively assess 287 Latino poultry-processing workers and 226 Latinos in other manual-labor occupations., Results: The prevalence of CTS was higher in poultry-processing (8.7%) compared with nonpoultry manual workers (4.0%; P < 0.0001). The adjusted odds ratio for the prevalence of CTS in poultry workers was 2.51 (95% confidence interval, 1.80-3.50) compared with nonpoultry workers. Within the poultry workers, those who performed packing, sanitation, and chilling had a trend toward less CTS than those who performed tasks requiring more repetitive and strenuous hand movements., Discussion: Latino poultry-processing workers have a high prevalence of CTS, which likely results from the repetitive and strenuous nature of the work.

Objective: To evaluate associations between poultry processing work and respiratory health among working Latino men and women in North Carolina., Methods: Between May 2009 and November 2010, 402 poultry processing workers and 339 workers in a comparison population completed interviewer-administered questionnaires. Of these participants, 279 poultry processing workers and 222 workers in the comparison population also completed spirometry testing to provide measurements of forced expiratory volume in 1 second and forced vital capacity., Results: Nine percent of poultry processing workers and 10% of workers in the comparison population reported current asthma. Relative to the comparison population, adjusted mean forced expiratory volume in 1 second and forced vital capacity were lower in the poultry processing population, particularly among men who reported sanitation job activities., Conclusions: Despite the low prevalence of respiratory symptoms reported, poultry processing work may affect lung function.

Objective: This study assessed college students' reports of tobacco screening and brief intervention by student health center providers., Participants: Participants were 3,800 students from 8 universities in North Carolina., Methods: Web-based survey of a stratified random sample of undergraduates., Results: Fifty-three percent reported ever visiting their student health center. Of those, 62% reported being screened for tobacco use. Logistic regression revealed screening was higher among females and smokers, compared to nonsmokers. Among students who were screened and who reported tobacco use, 50% reported being advised to quit or reduce use. Brief intervention was more likely among current daily smokers compared to current nondaily smokers, as well as at schools with higher smoking rates. Screening and brief intervention were more likely at schools with lower clinic caseloads., Conclusions: Results highlight the need to encourage college health providers to screen every patient at every visit and to provide brief intervention for tobacco users.

Objective: Insomnia has been linked to suicidal ideas and suicide death in cross-sectional and longitudinal population-based studies. A link between insomnia and suicide has not been previously examined in the setting of a clinical trial. Herein we describe the relationship between insomnia and suicidal thinking during the course of a clinical trial for depression with insomnia., Methods: Sixty patients aged 41.5±12.5 years (2/3 women) with major depressive episode and symptoms of insomnia received open-label fluoxetine for 9 weeks and also received blinded, randomized eszopiclone 3mg or placebo at bedtime after the first week of fluoxetine. Insomnia symptoms were assessed with the Insomnia Severity Index (ISI), and suicidal ideation was assessed with The Scale for Suicide Ideation (SSI). Depression symptoms were assessed with the depressed mood item and the anhedonia item from the Hamilton Rating Scale for Depression-24 (HRSD24), as well as a sum score for all non-sleep and non-suicide items from the HRSD (HRSD20). Measurements were taken at baseline and weeks 1, 2, 4, 6, and 8. SSI was examined by generalized linear mixed models for repeated measures as the outcome of interest for all 60 participants with ISI and various mood symptoms as independent variables, with adjustment for age, gender, treatment assignment, and baseline SSI., Results: Higher levels of insomnia corresponded to significantly greater intensity of suicidal thinking (p<0.01). The depressed mood item of the HRSD, and the sum of the HRSD20, both corresponded to greater suicidal thinking (p<0.001). The anhedonia item did not correspond with suicidal thinking. When both ISI and the depressed mood item, or ISI and the anhedonia item, were included together in the same model, the ISI remained an independent predictor of suicidal thinking., Conclusions: The results support the concept that insomnia may be a useful indicator for suicidal ideation and now extend this idea into clinical trials. Insomnia remains an independent indicator of suicidal ideation, even taking into account the core symptoms of depression such as depressed mood and anhedonia. The complaint of insomnia during a depression clinical trial might indicate that more direct questioning about suicide is warranted.

Study Objectives: Insomnia is associated with poor health related quality of life (HRQOL) in depressed patients. Prior clinical trials of hypnotic treatment of insomnia in depressed patients have shown improvement in HRQOL, but in these studies HRQOL was relegated to a secondary outcome, and objective measures of sleep were not undertaken., Design: Double-blind, randomized, placebo-controlled clinical trial., Setting: Outpatient clinic and sleep laboratory., Patients: 60 depressed, insomniac outpatients., Interventions: One week of open-label fluoxetine (FLX), followed by 8 more weeks of FLX combined with either eszopiclone (ESZ) 3 mg or placebo at bedtime., Measurements: The primary HRQOL measure was the daily living and role functioning subscale (DLRF) of the Basis-32. Other measures included the Q-LES-Q, self-reported sleep, PSG, actigraphy, depression severity (HRSD)., Results: At the end of randomized treatment, patients receiving ESZ had lower (better) DLRF scores (0.81 +/- 0.64) than those receiving placebo (1.2 +/- 0.72), p = 0.01. The effect size for DLRF was 0.62, indicating a moderate effect. An advantage for ESZ was also seen in other measures of HRQOL, and most assessments of antidepressant efficacy and sleep. Women reported better end of treatment HRQOL scores than men., Conclusions: ESZ treatment of insomnia in depressed patients is associated with multiple favorable outcomes, including superior improvement in HRQOL, depression severity, and sleep.

Objective: Attrition bias is an important issue in survey research on alcohol, tobacco, and other drug use. The issue is even more salient for Internet studies, because these studies often have higher rates of attrition than face-to-face or telephone surveys, and there is limited research examining the issue in the field of drug usage, specifically for college underclassmen. This study assessed whether measures of high-risk drinking and alcohol-related consequences were related to attrition groups ("stayers" or "leavers") in a cohort of college freshmen., Method: Data were collected in 2003 and 2004 from 2,144 first-year college students at 10 universities in the southeastern United States. Demographics, indicators of high-risk drinking, and alcohol-related consequences were compared between cohort stayers and leavers in statistical analyses using two methods., Results: Analyses indicated that cohort leavers reported significantly higher levels of high-risk drinking (past-30-day heavy episodic drinking, weekly drunkenness) and past-30-day smoking but not significantly increased alcohol-related consequences. The directionality of bias was modestly consistent across outcomes and comparison methods., Conclusions: The current study's findings suggest that intervention efforts to reduce smoking or high-risk drinking need to consider attrition bias during study follow-up or account for it in analyses.

Unlabelled: Collegiate football games provide multiple social opportunities for alcohol use by students over the course of the weekend. The goal of this study was to examine alcohol use and alcohol-related consequences on football game weekends to determine differences based on characteristics of the game., Methods: A random sample of students from two large, public universities in the United States completed a survey on the Sunday-Friday following a high-risk weekend (HRW, important, home game) and low-risk weekend (LRW, no home game or game of importance) (N = 3,238 total). The survey measured the number of days students drank (0-3) and got drunk (0-3) over the weekend and whether 1+ consequences were experienced due to one's own drinking (yes/no) and due to others' drinking (yes/no)., Results: Ordinal logistic regression analyses revealed greater odds of drinking alcohol (OR = 1.70, CI = 1.46-1.97) and getting drunk (OR = 1.49, CI = 1.27-1.76) on HRW versus LRW. Logistic regression analyses revealed greater odds of experiencing 1+ consequences as a result of one's own drinking (OR = 1.38, CI = 1.16-1.63) and experiencing 1+ consequences as a result of others' drinking (OR = 1.52, CI = 1.30-1.78) on HRW versus LRW., Discussion: These findings suggest that additional prevention efforts aimed at reducing risky drinking are needed over HRW and have implications for campus administrators, law enforcement, and substance abuse program coordinators.
