Passive and active tobacco exposure and children's lipid profiles
Zakhar, Joseph; Amrock, Stephen M; Weitzman, Michael
INTRODUCTIONDespite reductions in smoking rates, exposure to cigarette smoke remains common among US children and adolescents. In adults, active smoking and secondhand smoke (SHS) exposure have been linked to adverse changes in lipid profiles and increases in inflammatory markers. Evidence that such changes are present before adulthood remains limited, and the extent to which active smoking and SHS exposure affect these cardiovascular measures in children has not been thoroughly assessed.METHODSWe employed data from 2,008 individuals aged 12-19 years from the 2005-2010 National Health and Nutrition Examination Survey (NHANES). Comparisons of the lipid and inflammatory marker levels among active smokers, those exposed to SHS (as determined by serum cotinine levels), and those unexposed to tobacco smoke were made using linear regression with multiple propensity score adjustment.RESULTSCompared to unexposed children, lipid and inflammatory marker profiles did not differ among those exposed to SHS exposure. Among active smokers, differences compared to unexposed children were observed in triglyceride levels (beta = 8.5 mg/dL, P = 0.01), the ratio of triglycerides to HDL (beta = 0.2, P = 0.045), and LDL-C (beta = -4.1mg/dL, P = 0.03), though these did not reach levels of confirmatory statistical significance.CONCLUSIONSAfter accounting for sociodemographic characteristics and medical comorbidities, serum lipids and markers of systemic inflammation were not associated with SHS exposure. Tobacco smoke exposure in children may require longer durations of compounded effect before serum lipid abnormalities are detected.

Multiple biomarkers for mortality prediction in peripheral arterial disease
Amrock, Stephen M; Weitzman, Michael
Few studies have assessed which biomarkers influence mortality risk among those with peripheral arterial disease (PAD). We analyzed data from 556 individuals identified to have PAD (i.e. ankle-brachial index 0.9) with available measurements of C-reactive protein, the neutrophil-to-lymphocyte ratio (NLR), homocysteine, and the urinary albumin-to-creatinine ratio (UACR) in the 1999-2004 National Health and Nutrition Examination Survey. We investigated whether a combination of these biomarkers improved the prediction of all-cause and cardiovascular mortality beyond conventional risk factors. During follow-up (median, 8.1 years), 277 of 556 participants died; 63 deaths were attributed to cardiovascular disease. After adjusting for conventional risk factors, Cox proportional-hazards models showed the following to be most strongly associated with all-cause mortality (each is followed by the adjusted hazard ratio [HR] per 1 standard deviation increment in the log values): homocysteine (1.31), UACR (1.21), and NLR (1.20). UACR alone significantly predicted cardiovascular mortality (1.53). Persons in the highest quintile of multimarker scores derived from regression coefficients of significant biomarkers had elevated risks of all-cause mortality (adjusted HR, 2.45; 95% CI, 1.66-3.62; p for trend, <0.001) and cardiovascular mortality (adjusted HR, 2.20; 95% CI, 1.02-4.71; p for trend, 0.053) compared to those in the lowest two quintiles. The addition of continuous multimarker scores to conventional risk factors improved risk stratification of all-cause mortality (integrated discrimination improvement [IDI], 0.162; p<0.00001) and cardiovascular mortality (IDI, 0.058; p<0.00001). In conclusion, the addition of a continuous multimarker score to conventional risk factors improved mortality prediction among patients with PAD.

Midwakh/dokha tobacco use in the Middle East: much to learn
Vupputuri, S; Hajat, C; Al-Houqani, M; Osman, O; Sreedharan, J; Ali, R; Crookes, A E; Zhou, S; Sherman, S E; Weitzman, M
Many alternative tobacco products (ATPs), such as hookahs, have grown in popularity and use beyond their locale of origin and are therefore becoming a significant global public health concern. This article provides an overview of an under-reported and understudied ATP, dokha, which is smoked in a midwakh pipe. It describes the state of tobacco control in the Arabian Gulf region where midwakh smoking appears to be most common, the history of midwakh and dokha use, and what is known about midwakh smoking from the published literature. On the basis of the stark lack of data on midwakh use, we suggest priority areas to focus future research. Preliminary data and observations from health providers and the public health sector suggest that midwakh smoking may pose challenges to the tobacco control efforts in the Arabian Gulf region. If it is emerging as a new ATP outside this region, there could be a significant impact on tobacco control strategies globally.

Knowledge, Beliefs, Behaviors, and Social Norms Related to Use of Alternative Tobacco Products Among Undergraduate and Graduate Nursing Students in an Urban U.S. University Setting
VanDevanter, Nancy; Zhou, Sherry; Katigbak, Carina; Naegle, Madeline; Sherman, Scott; Weitzman, Michael
PURPOSE: The purpose of the study was to assess nursing students' knowledge, beliefs, behaviors, and social norms regarding use of alternative tobacco products (ATPs). DESIGN AND METHODS: This anonymous online survey was conducted with all students enrolled in a college of nursing. The survey utilized measures from several national tobacco studies to assess knowledge and beliefs about ATPs (hookahs, cigars or cigarillos, bidis, kreteks, smokeless tobacco, electronic cigarettes) compared to cigarettes, health effects of ATPs, personal use of ATPs, and social norms. Data were analyzed in SPSS 22.0 (SPSS Inc., Chicago, IL, USA). Descriptive statistics and frequencies were performed for basic sociodemographic data. Paired samples t tests were performed to determine differences for scaled measures. FINDINGS: Nursing students demonstrated very low levels of knowledge about ATPs and their health consequences, despite high rates of ATP personal use. About 76% of participants reported use of one or more ATPs once or more in their lifetimes. A greater proportion of students had used hookahs or waterpipes (39.6%) compared to cigarettes (32.7%). CONCLUSIONS: Nurses' lack of knowledge about the emerging use and health threats associated with ATPs may undermine their ability to provide appropriate tobacco cessation counseling. Research is needed to identify gaps in nurses' education regarding tobacco cessation counseling and to develop new counseling approaches specific to use of ATPs. CLINICAL RELEVANCE: Nurses play critical roles in counseling their patients for tobacco cessation. Further research and education about the risks presented by ATPs are critical to reducing excess tobacco-related mortality.

A Study of the Use, Knowledge, and Beliefs About Cigarettes and Alternative Tobacco Products Among Students at One U.S. Medical School
Zhou, Sherry; Van Devanter, Nancy; Fenstermaker, Michael; Cawkwell, Philip; Sherman, Scott; Weitzman, Michael
PURPOSE: In the United States, the prevalence of the use of alternative tobacco products (ATPs) (e.g., hookahs, e-cigarettes, cigars/cigarillos) has increased sharply. As future health care providers, medical students will play a critical role in health promotion and disease prevention. This study investigated medical students' use, knowledge, and beliefs about cigarettes and ATPs. METHOD: In 2014, the authors surveyed all students enrolled at one medical school in New York City. The survey included questions about personal use of tobacco products, perceptions about the harms of ATPs and their role in disease causation, education about ATPs, and cessation training and practices related to ATPs and cigarettes. The authors compared results across medical school classes. RESULTS: Of 720 students, 431 (59.9%) completed the survey. Of those, 64 (14.7%) were current users of tobacco or smoking products, including cigarettes (17; 3.9%), ATPs (21; 4.8%), or marijuana (39; 8.9%). Many believed that ATPs contributed less than cigarettes to various diseases. Respondents received less cessation training regarding ATPs than cigarettes (P < .0001). They felt less confident providing ATP cessation counseling than cigarette cessation counseling (P < .0001) and were less likely to report counseling patients on ATP cessation than cigarette cessation (46 [10.7%] versus 280 [64.8%], P < .0001). CONCLUSIONS: A concerning percentage of surveyed medical students use tobacco products, including ATPs, and lack the knowledge, education, and cessation counseling skills to provide accurate information about them to patients. ATP education should be added to medical school curricula to address this gap.

Air quality in New York City hookah bars
Zhou, Sherry; Weitzman, Michael; Vilcassim, Ruzmyn; Wilson, Jennifer; Legrand, Nina; Saunders, Eric; Travers, Mark; Chen, Lung-Chi; Peltier, Richard; Gordon, Terry
BACKGROUND: Hookahs are increasingly being used in the USA and elsewhere. Despite the popularity of hookah bars, there is a paucity of research assessing the health effects of hookah smoke, and although New York City (NYC) bans indoor tobacco smoking, hookah lounges claim that they only use herbal products without tobacco. This study investigated levels of multiple indices of indoor air pollution in hookah bars in NYC. METHODS: Air samples were collected in 8 hookah bars in NYC. Along with venue characteristics, real-time measurements of fine particulate matter (PM2.5), black carbon (BC), and carbon monoxide (CO), and total gravimetric PM, elemental carbon (EC), organic carbon (OC), and nicotine were collected in 1-2 hour sessions. RESULTS: Overall, levels of indoor air pollution increased with increasing numbers of active hookahs smoked. The mean (SD) real time PM2.5 level was 1179.9 (939.4) microg/m(3), whereas the filter-based total PM mean was 691.3 (592.6) microg/m(3). The mean real time BC level was 4.1 (2.3) microg/m(3), OC was 237.9 (112.3) microg/m(3), and CO was 32 (16) ppm. Airborne nicotine was present in all studied hookah bars (4.2 (1.5) microg/m(3)). CONCLUSIONS: These results demonstrate that despite the ban on smoking tobacco products, at the very least, some NYC hookah bars are serving tobacco-based hookahs, and have elevated concentrations of indoor air pollutants that may present a health threat to visitors and employees. Therefore, there is an urgent need for better air quality monitoring in such establishments and policies to combat this emerging public health threat.

Uncovering risky behaviors of expatriate teenagers in the United Arab Emirates: A survey of tobacco use, nutrition and physical activity habits
Asfour, Leena W; Stanley, Zachary D; Weitzman, Michael; Sherman, Scott E
BACKGROUND: Tobacco use and unhealthy lifestyle habits amongst youth contribute to most major health issues in the United Arab Emirates (UAE) and worldwide. However up to date and comprehensive statistics are not available on the current behavior, experimentation and environmental influences on teenagers in the UAE's expatriate community, who are greatly impacted by the country's culture and environment, as well as bringing influences from their cultures of origin. Expatriates comprise a majority of the UAE population, making them an important subset of the population to study. METHOD: To address this gap in knowledge, a survey was conducted to collect information on tobacco use, physical activity and nutrition behaviors, anti-tobacco media/legislation effectiveness and health education gaps. RESULTS: Our results provide a summary on each of these topics with regards to ninth grade expatriates in the UAE. We offer the first statistics on dokha use in this age group and uncover signs of underlying eating disorders. CONCLUSIONS: In conclusion, we call for a tobacco use, nutrition and physical activity intervention targeted at this age group of UAE expatriates.

Persistent racial and ethnic differences in location of death for children with cancer
Cawkwell, Philip B; Gardner, Sharon L; Weitzman, Michael
BACKGROUND: Approximately one in 285 children will be diagnosed with cancer before reaching their 20th birthday. While both oncologists and parents report a preference that these children die at home rather than in a hospital, there are limited data exploring this issue in depth. PROCEDURE: We performed a retrospective analysis of national-level data from 1999 to 2011 from the National Center for Health Statistics "Underlying Cause of Death" database. Characteristics investigated included sex, race, age, ethnicity, cancer type, geographic location, and population density where the child lived. RESULTS: Of the 2,130 children with a death attributable to neoplasm in 2011, 37.6% (95% CI, 35.5-39.6%) died at home compared to 36.9% (95% CI, 35.0-38.8%) in 1999. In 2011, there were statistically significant racial differences between white, black, and Hispanic children across nearly every age group, with white children consistently most likely to die at home. Children of non-Hispanic origin were significantly more likely to die at home than Hispanic children (40.3% vs. 29.3%, P < 0.001). Children with CNS tumors are more likely to die at home than children with neoplasms as a whole, while children with leukemia are less likely. Statistically significant differences by race and ethnicity persist regardless of cancer type. CONCLUSIONS: There has been no significant change in the rate of children with cancer who die at home over the past decade. Racial and ethnic differences have persisted in end of life care for children with cancer with white non-Hispanic children being most likely to die at home. Pediatr Blood Cancer 2015;62:1403-1408.

Tracking Hookah Bars in New York: Utilizing Yelp as a Powerful Public Health Tool
Cawkwell, Philip B; Lee, Lily; Weitzman, Michael; Sherman, Scott E
BACKGROUND: While cigarette use has seen a steady decline in recent years, hookah (water pipe) use has rapidly increased in popularity. While anecdotal reports have noted a rise in hookah bars, methodological difficulties have prevented researchers from drawing definitive conclusions about the number of hookah bars in any given location. There is no publicly available database that has been shown to reliably provide this information. It is now possible to analyze Internet trends as a measure of population behavior and health-related phenomena. OBJECTIVE: The objective of the study was to investigate whether Yelp can be used to accurately identify the number of hookah bars in New York State, assess the distribution and characteristics of hookah bars, and monitor temporal trends in their presence. METHODS: Data were obtained from Yelp that captures a variety of parameters for every business listed in their database as of October 28, 2014, that was tagged as a "hookah bar" and operating in New York State. Two algebraic models were created: one estimated the date of opening of a hookah bar based on the first Yelp review received and the other estimated whether the bar was open or closed based on the date of the most recent Yelp review. These findings were then compared with empirical data obtained by Internet searches. RESULTS: From 2014 onward, the date of the first Yelp review predicts the opening date of new hookah bars to within 1 month. Yelp data allow the estimate of such venues and demonstrate that new bars are not randomly distributed, but instead are clustered near colleges and in specific racial/ethnic neighborhoods. New York has seen substantially more new hookah bars in 2012-2014 compared with the number that existed prior to 2009. CONCLUSIONS: Yelp is a powerful public health tool that allows for the investigation of various trends and characteristics of hookah bars. New York is experiencing tremendous growth in hookah bars, a worrying phenomenon that necessitates further investigation.
