Effectiveness of Interventions to Improve Oral Cancer Knowledge: a Systematic Review

Oral cancer is prone to late-stage diagnosis, and subsequent low five-year survival rates. A small number of interventions or campaigns designed to enhance knowledge of risk factors and symptoms associated with oral cancer have been attempted in the UK, US, and some other countries. The purpose of this systematic review is to assess the effectiveness of interventions designed to improve oral cancer knowledge. We searched five databases to identify randomized controlled trials (RCTs) and non-randomized/quasi-experimental (NR/QE) studies targeting the general population or high-risk groups (tobacco users or alcohol consumers), aged ≥15 years, and reporting the outcomes of individual and/or community level interventions. Two co-authors independently identified relevant studies, extracted data, and assessed the risk of bias. Adhering to PRISMA guidelines, 27 (eight RCTs and 19 NR/QE studies) of the 551 studies identified from the five databases met the inclusion criteria. All RCTs and nine NR/QE studies used either printed materials, health education sessions, multimedia aids, or some combinations of these tools. The other ten NR/QE studies were community-based and used mass media campaigns to increase oral cancer awareness. Overall, the majority of studies significantly improved oral cancer knowledge; however, heterogeneity in study design and variation in measurement tools made it difficult to compare outcomes. Findings suggest that individual and/or community level interventions are generally effective in increasing knowledge of oral cancer risk factors, signs and symptoms, and/or its early diagnosis and prevention strategies among the general population or high-risk groups. However, the long-term benefits of these interventions are understudied.

State-specific Prevalence and Factors Associated With Current Marijuana, ENDS, and Cigarette use Among US Adults With Asthma

Background

The use of marijuana (MJ), combustible cigarettes (hereafter cigarettes), and electronic nicotine delivery systems (ENDS) is widespread among United States (US) adults and linked to worsening respiratory symptoms, especially among adults with asthma. This study examined state-specific prevalence and factors associated with MJ, ENDS, and cigarette use among US adults with asthma.

Methods

We analyzed data of 41 974 adults aged ≥18 years having self-reported current asthma from the 2018 Behavioral Risk Factor Surveillance System (BRFSS). We reported weighted prevalence to account for complex survey design and performed multivariable logistic regression models to examine factors associated with current use of MJ, ENDS, and cigarettes.

Results

Overall prevalence of current MJ, ENDS, and cigarette use among adults with asthma was 14.5%, 6.6%, and 27.2%, respectively. Our results showed the US states and territories with highest and lowest use prevalence for MJ (California: 23.6% vs Guam: 3.2%), ENDS (Indiana: 12.8% vs North Dakota: 4.0%), and cigarettes (West Virginia: 42.1% vs Guam: 12.3%). Both MJ and ENDS users were more likely to be male, younger, and live in an urban area, but MJ users were more likely and ENDS users less likely to be Non-Hispanic (NH) American Indian/Alaskan Native. Cigarette users were more likely to be older, have at least 1 health condition, and were less likely to be NH Black or Hispanic and college-educated.

Conclusion

Many US adults with asthma use MJ, ENDS, and cigarettes. Our findings provide insights for clinicians about the urgent need for effective interventions to reduce tobacco and MJ use among adults with asthma.

"Scary and Effective, Definitely Pushes Me to Quit Smoking": Developing Waterpipe Pictorial Health Warnings Targeting Young Adults in Lebanon

INTRODUCTION

Waterpipe (WP) smoking is the leading tobacco use method among young adults in Lebanon. WP use is harmful, yet misperceptions about its safety exist. Implementing pictorial health warning labels (HWLs) on WP products is a promising strategy to correct this misperception. This study aimed to culturally adapt a set of 12 pictorial HWLs recently developed by an international expert panel to young adults in Lebanon. HWLs were grouped into four themes: WP health risks, WP harm to others, WP-specific harms, and WP harm compared to cigarettes.

AIMS AND METHODS

We conducted nine focus groups among WP smokers and nonsmokers (N = 77; 52% females; age 18-34 years) to explore participants' perceptions of the developed HWLs on attention, reaction (fear, avoidance), effectiveness (harm perception), and improvement (design/content, relatedness). Sessions were audio-taped, transcribed verbatim, and analyzed using directed qualitative content analysis.

RESULTS

Emotionally provocative warnings were perceived as most effective, while symbolic and abstract warnings were found not believable. Warnings depicting visible bodily health effects and harm to babies seemed most promising. Participants were generally skeptical about Theme 4 because it might encourage switching to cigarettes. For cultural adaptation, participants recommended using shorter text with affirmative phrases, increasing the picture's size and improving their quality, adding the WP device picture to enhance HWLs' relatability, and develop testimonial messages that depict real people and stories.

CONCLUSIONS

Results will provide Lebanon and perhaps other countries in the Eastern Mediterranean Region with evidence-based HWLs that they can further develop, test, and implement within their specific culture.

IMPLICATIONS

Results provide Lebanon with evidence-based WP-specific pictorial HWLs that can be further developed and tested. HWLs provoking negative affect, with visible health consequences, and depicting harm to babies are promising. Participants recommended using definitive scientific claims presenting the health risks in numerical form. However, this needs to be balanced against protecting the credibility of HWLs scientifically and legally. Increasing the HWLs size and adding the WP device picture to the HWLs can enhance their relatability. Further research can help address some questions raised by this study, such as the potential of testimonial warnings that depict real people.

Prevalence and predictors of waterpipe smoking initiation and progression among adolescents and young adults in waves 1-4 (2013-18) of the Population Assessment of Tobacco and Health (PATH) study

BACKGROUND

Waterpipe tobacco (WPT) smoking has increased among the young population in the United States (US). This study assessed the extent and predictors of WPT smoking initiation and progression among US adolescents (12-17 years) and young adults (18-24 years) longitudinally.

METHODS

We analyzed data from 4 waves (2013-2018) of the Population Assessment of Tobacco and Health (PATH) study comprising 10,692 respondents (adolescents=5,428 and young adults=5,264). Kaplan-Meier survival method estimated probabilities of WPT initiation and progression. Cox proportional hazards regression models delineated predictors of the outcomes.

RESULTS

Between 2013 to 2018, 4.8% of adolescents initiated and 10.6% progressed WPT smoking. Among young adults, 18.5% initiated and 14.1% progressed WPT smoking during the same time interval. Predictors among adolescents included, WPT initiation: Hispanic ethnicity (adjusted odds ratio (aHR)=1.75, 95% confidence interval (CI)=1.23-2.49), lower harm perception (aHR=2.89, 95% CI=2.10-3.98), and other tobacco products use (aHR=3.97, 95% CI=2.73-5.78); WPT progression: illicit drug use (aHR=4.60, 95% CI=1.99-10.67). Predictors among young adults included, WPT initiation: non-Hispanic Black (aHR=2.31, 95% CI=1.78-3.00), Hispanic (aHR=1.77, 95% CI=1.34-2.33), lower harm perception (aHR=2.77, 95% CI=2.19-3.50), and other tobacco products use (aHR=3.14, 95% CI=2.25-4.38); WPT progression: non-Hispanic Black (aHR=1.51 95% CI=1.09-2.10), lower harm perception (aHR=1.80, 95% CI=1.41-2.30), and alcohol use (aHR=1.61, 95% CI=1.13-2.30).

CONCLUSIONS

Results indicate a high prevalence of WPT initiation and progression among adolescents and young adults over time, with minority racial/ethnic groups being at greater risk for both. WPT-specific risk communication interventions (e.g., educational campaigns and health warning labels) are warranted to limit WPT smoking among young people.

Longitudinal associations between insomnia symptoms and all-cause mortality among middle-aged and older adults: a population-based cohort study

To date, there is no scientific consensus on whether insomnia symptoms increase mortality risk. We investigated longitudinal associations between time-varying insomnia symptoms (difficulty initiating sleep, difficulty maintaining sleep, early-morning awakening, and nonrestorative sleep) and all-cause mortality among middle-aged and older adults during 14 years of follow-up. Data were obtained from 2004 through 2018 survey waves of the Health and Retirement Study in the United States for a population-representative sample of 15 511 respondents who were ≥50 years old in 2004. Respondents were interviewed biennially and followed through the end of the 2018 survey wave for the outcome. Marginal structural discrete-time survival analyses were employed to account for time-varying confounding and selection bias. Of the 15 511 cohort respondents (mean [±SD] age at baseline, 63.7 [±10.2] years; 56.0% females), 5878 (31.9%) died during follow-up. At baseline (2004), 41.6% reported experiencing at least one insomnia symptom. Respondents who experienced one (HR = 1.11; 95% CI: 1.03-1.20), two (HR = 1.12; 95% CI: 1.01-1.23), three (HR = 1.15; 95% CI: 1.05-1.27), or four (HR = 1.32; 95% CI: 1.12-1.56) insomnia symptoms had on average a higher hazard of all-cause mortality, compared to those who were symptom-free. For each insomnia symptom, respondents who experienced difficulty initiating sleep (HR = 1.12; 95% CI: 1.02-1.22), early-morning awakening (HR = 1.09; 95% CI: 1.01-1.18), and nonrestorative sleep (HR = 1.17; 95% CI: 1.09-1.26), had a higher hazard of all-cause mortality compared to those not experiencing the symptom. The findings demonstrate significant associations between insomnia symptoms and all-cause mortality, both on a cumulative scale and independently, except for difficulty maintaining sleep. Further research should investigate the underlying mechanisms linking insomnia symptoms and mortality.

Factors Associated with E-Cigarette Quit Intention Among Adolescents in the United States

Background: Given increasing use of e-cigarettes among adolescents in the United States and its potential for nicotine addiction, encouraging adolescents to quit using these products has become a public health priority. This study examined factors at various socio-ecological levels associated with e-cigarette quit intention (pre-contemplation, contemplation, or preparation) using the Stages of Change of the Trans-theoretical Model among the U.S. adolescents. Methods: We used cross-sectional data from the past 30-day adolescent exclusive e-cigarette users participating in Wave 4 of the Population Assessment of Tobacco and Health study (n = 349). Weighted adjusted multinomial logistic regression models were used to analyze the data. Results: Compared to pre-contemplators and contemplators, preparators were more likely to believe that nicotine in e-cigarettes was "very/extremely harmful" (vs. "not at all harmful") to health (p < 0.001) and people cause a "lot of harm" (vs. "no harm") to themselves when they use e-cigarettes (p < 0.001). In comparison to pre-contemplators, contemplators and preparators were more likely to report that their parents/guardians talked with them about not using e-cigarettes than those whose parents/guardians did not talk with them (p < 0.001). Additionally, contemplators and preparators were also more likely to report that they "often/very often" (vs. never) noticed health warnings on e-cigarette packages (p < 0.001). Conclusion: Our findings suggest that harm perception, influence of family, and e-cigarette health warnings are some of the important factors associated with the stages of change for intention to quit among adolescent e-cigarette users. This study will help public health practitioners and researchers design multi-level e-cigarette cessation interventions for adolescents.

Country Participation in the WHO Framework Convention on Tobacco Control Health Warnings Database

Background

The World Health Organization’s (WHO) Framework Convention on Tobacco Control (FCTC) Health Warnings Database is an online, publicly available resource created for countries to upload and share pictorial health warnings for tobacco packaging. The purpose of this study was to evaluate the extent to which the database is used by countries for the sharing of pictorial warnings.

Methods

The study’s sample included parties to the FCTC who required graphic health warning labels on cigarette packaging from. Those countries were categorized as having a low, middle, and high Socio-Demographic Index (SDI). The Health Warnings Database was then analyzed for those countries’ unique pictorial images, as well as the number of pictorials that were shared between countries.

Results

Of the 110 countries that required pictorial warnings on cigarette packaging, only 53 (48%) voluntarily contributed pictorials to the database, with most of those (53%) being high SDI-level countries. There were 342 unique pictorials on the database, with 62 images posted by seven countries that were used by 13 other countries.

Conclusion

While sharing was evident from the database, there remains a need for more countries to upload the pictorials to the database. There is also a need to expand the database to include alternative tobacco products, such as waterpipe tobacco and e-cigarettes.

COVID-19 Vaccine Hesitancy and Its Determinants Among Adults with a History of Tobacco or Marijuana Use

Decreasing COVID-19 vaccine hesitancy is an urgent challenge in the US. This study aimed to examine COVID-19 vaccine hesitancy among U.S. adults with a history of using tobacco products or marijuana. Data were collected online in 2020-2021 including respondents' willingness to accept a COVID-19 vaccine, factors that may promote vaccine acceptance, and prior history of influenza vaccination. Logistic regression models were conducted to estimate the associations between vaccine hesitancy and demographic characteristics, substance use, the impact of the COVID-19 pandemic, and prior influenza vaccination. Among 387 respondents, 49.1% were willing to receive a COVID-19 vaccine, 26.0% were unwilling, and 24.9% were "not sure." Blacks, suburban or rural residents, those who lived by themselves or with a family with five members or above, those who were not stressed because of the COVID-19 pandemic were more likely to say "no" to a COVID-19 vaccine. Respondents who never, only once, or during some years received an influenza vaccine were 7.0, 6.2, and 5.2 times more likely to say "no" to a COVID-19 vaccine than respondents who received an influenza vaccination every year or almost every year. The use of cigarettes, e-cigarettes, and marijuana, as well as heavy drinking of alcohol, were not associated with COVID-19 hesitancy. The associations between demographic factors and vaccine hesitancy were roughly similar for COVID-19 and influenza vaccines. Although various demographic groups have different levels of vaccine hesitancy and also have different factors to increase their acceptance, addressing misinformation related to COVID-19 vaccines, particularly concern about the safety of the vaccines is crucial in general.

Quitline Information Included on Cigarette Packaging: An Assessment of Country Adherence to WHO FCTC Guidelines, 2007 to 2018

The purpose of this study is to evaluate country adherence to the World Health Organization's (WHO) Framework Convention on Tobacco Control (FCTC) guidelines in terms of including quitline information on cigarette packaging. Data were gathered from the WHO's Global Health Observatory database. The study included countries that were signatories to the FCTC, had a toll-free quitline, and required health warnings on cigarette packaging. Countries were then classified by income level according to the World Bank. From 2007 to 2018, the number of countries that established a quitline increased from 34 to 60. During the same timeframe among those countries, the number of countries that included information about the quitline on cigarette packaging increased from 5 to 37, with a larger proportion (79%) of high-income countries promoting their quitlines on cigarette packaging compared to middle-income (45%) countries. Although there was an increase in adherence to the WHO FCTC guidelines, there is still a need for several countries to include quitline information on cigarette packaging.

Characteristics of flavored and non-flavored waterpipe tobacco users: a real-world setting study

We aimed to compare sociodemographic characteristics, smoking patterns, beliefs and perceptions, nicotine dependence, and psychological indicators between flavored waterpipe (WP) tobacco (FWT) and non-flavored WP tobacco (non-FWT) smokers in Iran. A cross-sectional study was conducted in 94 WP-serving venues surrounding Tehran and Ardabil metropolitans in Iran. Convenience sampling was applied to select 900 current WP smokers [508 (56%) FWT-only and 392 (44%) non-FWT-only smokers] aged 18 years and older. Multivariable logistic regression was used to examine the independent characteristics of FWT and non-FWT smokers. Compared to non-FWT smokers, FWT smokers were younger (adjusted odds ratio [AOR]=0.88, 95% confidence interval [CI]: 0.87-0.90) and more likely to have ≥ 1 sibling who smoked WP (AOR=1.54, 95% CI: 1.06-2.24), share WP with others (AOR=2.52, 95% CI: 1.68-3.77), report current cigarette smoking (AOR=2.05, 95% CI: 1.23-3.42), and report confidence in quitting at any time (AOR=3.64, 95% CI: 2.45-5.39). FWT smokers were less likely to have seen (AOR=0.40, 95% CI: 0.27-0.60) or read (AOR=0.44, 95% CI: 0.24-0.80) warning messages on WP tobacco packages relative to non-FTW smokers. The most common self-reported reason for smoking WP was entertainment for both groups, followed by stress relief for non-FWT smokers and the escape from loneliness for FWT smokers. FWT-only smokers differ from non-FWT-only smokers in several aspects including being younger, having more positive beliefs and perceptions regarding WP use, and having higher cigarette smoking prevalence. These findings will help in developing more effective and targeted policies and cessation interventions for WP smokers according to flavor type they use, especially in the Middle East.

Insomnia symptoms and incident heart failure: a population-based cohort study

AIMS

Heart failure (HF) is an ongoing epidemic and a serious clinical and public health issue. Currently, little is known about prospective associations between insomnia symptoms and HF incidence. We investigated the longitudinal associations between time-varying insomnia symptoms (difficulty initiating sleep, difficulty maintaining sleep, early-morning awakening, non-restorative sleep) and incident HF.

METHODS AND RESULTS

Data were obtained from the Health and Retirement Study in the US for a population-representative sample of 12,761 middle-aged and older adults (age ≥ 50 years; mean [SD] age, 66.7 [9.4] years; 57.7% females) who were free from HF at baseline in 2002. Respondents were followed for 16 years for incident HF. We employed marginal structural discrete-time survival analyses to adjust for potential time-varying biological, psycho-cognitive, and behavioral factors and to account for bias due to differential loss to follow-up. At baseline, 38.4% of the respondents reported experiencing at least one insomnia symptom. During the 16-year follow-up, 1,730 respondents developed incident HF. Respondents experiencing one (hazard ratio [HR]=1.22; 95% CI: 1.08-1.38), two (HR=1.45; 95% CI: 1.21-1.72), three (HR=1.66; 95% CI: 1.37-2.02), or four (HR=1.80; 95% CI: 1.25-2.59) insomnia symptoms had a higher hazard of incident HF than asymptomatic respondents. Respondents that had trouble initiating sleep (HR=1.17; 95%CI: 1.01-1.36), maintaining sleep (HR=1.14; 95% CI: 1.01-1.28), early-morning awakening (HR=1.20; 95% CI: 1.02-1.43), or non-restorative sleep (HR=1.25; 95% CI: 1.06-1.46) had a higher hazard of incident HF than asymptomatic respondents.

CONCLUSION

Insomnia symptoms, both cumulatively and individually, are associated with incident HF. Public health awareness and screening for insomnia symptoms in at-risk populations should be encouraged to reduce HF incidence.

COVID-19 and beliefs about tobacco use: an online cross-sectional study in Iran

There is mixed evidence surrounding the relationship between tobacco use and COVID-19 infection/progression. The current study investigates beliefs and tobacco use behaviors and COVID-19 infection among a sample of smokers and never-smokers. Data were collected using an online survey distributed through Telegram, a cloud-based social media networking application in Iran from April 1 to May 31, 2020. The study participants included never-smokers (n = 511), current (past-month) waterpipe smokers (n = 89), current cigarette smokers (n = 158), and ex-smokers (n = 172). Multinomial logistic regression was used to compare tobacco use groups with never- smokers on beliefs, controlling for potential confounders. The study participants (n = 944) was mostly male (64%), had > high school education (76%), and lived in an urban area (91%), with mean ± SD age of 35.3 ± 10.8. Key findings of this study are that compared with never-smokers: (1) cigarette smokers were less likely to believe that smoking cigarette can lead to spreading COVID-19; (2) waterpipe smokers were more likely to believe that smoking waterpipe at home was a safe practice, that waterpipe protects against COVID-19, and smoking waterpipe may lead to a more rapid recovery from COVID-19; (3) both waterpipe and cigarette smokers believed that using e-cigarettes in public places was a safe practice during the COVID-19 pandemic; and (4) more than half of the ex-smokers stopped smoking due to COVID-19 and most of them planned to continue abstaining from smoking after the pandemic. Our findings underscore the need to raise awareness about the unsupported claims of a lower hazard of using tobacco products or possible protective effects against COVID-19 and to promote cessation programs.

Smoking Cessation among Pregnant and Postpartum Women from Low-Income Groups in the United States

INTRODUCTION

Pregnancy creates a unique window of opportunity for smoking cessation. However, pregnant women from underserved groups can face personal, social, and environmental challenges that impede quitting. This study draws upon the socioecological framework to explore perspectives on smoking cessation among pregnant and postpartum women from low-income groups in the mid-South of the United States.

METHODS

Semistructured interviews were conducted with 60 women who were pregnant or postpartum. Data were analyzed in Dedoose qualitative software using the directed content analysis approach.

RESULTS

Findings reveal that at the individual level, motivations for smoking cessation included the fact of being pregnant, risks associated with the infant's health, and desire to breastfeed. However, some pregnant women perceived that slowing down on smoking during pregnancy was adequate to prevent harm to their fetuses. Individual-level factors that made smoking cessation difficult included nicotine addiction and habit, boredom, stressful life circumstances, fear of weight gain, and perceived lack of willpower. At the interpersonal level, living in a smoke-free environment where loved ones do not smoke and emotional and practical support from social network members including partners and family members were thought to facilitate smoking cessation. At the organizational level, access to nicotine replacement therapies and counseling aided in their abilities to quit smoking. At the policy level, pregnant women viewed increase in cigarette prices, warning labels on the cigarette pack, and the potential for a ban on cigarette sales as having some effect in helping them quit smoking.

DISCUSSION

This study offers theoretical insights into factors that function as barriers or facilitators of smoking cessation among pregnant and postpartum women from low-income groups in the United States. Designing multilevel smoking cessation interventions while considering the interplay of individual, interpersonal, organizational, and policy level factors may lead to better cessation outcomes.

Novel Insights into Young Adults' Perceived Effectiveness of Waterpipe Tobacco-Specific Pictorial Health Warning Labels in Lebanon: Implications for Tobacco Control Policy

This study aims to explore the perceived effectiveness of waterpipe (WP) tobacco specific health warning labels (HWLs) among young adult WP smokers and nonsmokers in Lebanon. Before participating in focus group discussions, participants (n = 66; WP smokers n = 30; nonsmokers n = 36; age 18-33) completed a brief survey to rate the effectiveness of 12 HWLs' and rank them according to four risk themes (WP health effects, WP harm to others, WP-specific harm, and WP harm compared to cigarettes). Differences in HWLs ratings by WP smoking status were examined and the top-ranked HWL in each theme were identified. HWLs depicting mouth cancer and harm to babies were rated as the most effective by both WP smokers and non-smokers. WP smokers rated HWLs which depicted harm to children and infants as more effective than non-smokers. The top-ranked HWLs for perceived overall effectiveness were those depicting "oral cancer", "harm to babies", "orally transmitted diseases" and "mouth cancer". HWLs depicting oral lesions and harm to babies were rated as most effective, while HWLs showing the harmful effects of WP secondhand smoke on infants and children were rated as less effective by nonsmokers compared to smokers. Our study provides evidence on the potential effectiveness of HWLs for further evaluation in Lebanon and the Eastern Mediterranean region. The results will inform and guide the development and implementation of tobacco control policy.

Trends and Factors Related to Blunt Use in Middle and High School Students, 2010-2020

BACKGROUND AND OBJECTIVES

Blunt use is a popular mode of marijuana consumption among adolescents in the United States, but little is known about how its prevalence has changed over time or factors associated with its use. With this study, we assessed trends and correlates of past (ever used but not in the past 30 days) and current (used in past 30 days) blunt use among adolescents in Florida.

METHODS

We analyzed data from 2010-2020 cross-sectional, statewide representative Florida Youth Tobacco Surveys that comprised 461 706 middle and high schoolers using Joinpoint to calculate annual percentage change (APC) in the weighted prevalence of past and current blunt use. A weighted multivariable regression model was developed by using 2019-2020 Florida Youth Tobacco Survey data to examine the factors associated with past and current blunt use.

RESULTS

Whereas the prevalence of past (APC = -5.32%) and current (APC = -5.28%) blunt use significantly decreased from 2010 to 2015, an increasing trend in current use prevalence (APC = 14.91%) was observed from 2015 to 2018 and has been approximately constant ever since. Similar increasing trends were observed in current blunt use among female students (APC = 14.92%), middle schoolers (19.57%), and non-Hispanic (NH) white students (APC = 11.12%) from 2016 to 2020. Several factors were consistently associated with greater odds of both past and current blunt use for both middle and high schoolers, including older age, being NH Black (versus NH white), past and current use of cigarettes, electronic cigarettes, hookah, cigars, and ever vaping marijuana.

CONCLUSIONS

Although blunt use among Florida youth decreased from 2010 to 2015, substantial increases were observed since 2015, suggesting that existing tobacco control programs should incorporate marijuana (and blunt) modules into existing tobacco and nicotine prevention programs.

An Overview of the Epidemiologic, Diagnostic and Treatment Approaches of COVID-19: What do We Know?

Background: In late December 2019, a new infectious respiratory disease (COVID-19) was reported in a number of patients with a history of exposure to the Huanan seafood market in China. The World Health Organization officially announced the COVID-19 pandemic on March 11, 2020. Here, we provided an overview of the epidemiologic, diagnostic and treatment approaches associated with COVID-19. Methods: We reviewed the publications indexed in major biomedical databases by December 20, 2020 or earlier (updated on May 16, 2021). Search keywords included a combination of: COVID-19, Coronavirus disease 2019, SARS-CoV-2, Epidemiology, Prevention, Diagnosis, Vaccine, and Treatment. We also used available information about COVID-19 from valid sources such as WHO. Results and Conclusion: At the time of writing this review, while most of the countries authorized COVID-19 vaccines for emergency use starting December 8, 2020, there is no a definite cure for it. This review synthesizes current knowledge of virology, epidemiology, clinical symptoms, diagnostic approaches, common treatment strategies, novel potential therapeutic options for control and prevention of COVID-19 infection, available vaccines, public health and clinical implications.

A Group-based Modeling Approach to Identify Developmental Trajectories of Nicotine Dependence Among Lebanese Adolescents Waterpipe Smokers

INTRODUCTION

Adolescence represents a critical period in which nicotine dependence(ND) symptoms are developing. Little is known about waterpipe(WP) smoking and developmental trajectories of ND criteria across adolescence. Here, we aimed to identify ND trajectories from early to late adolescence in current(past 30 days) WP smokers and examine baseline correlates of each identified trajectory, using the International Classification of Diseases, 10thVersion(ICD10).

METHODS

The analytical sample consisted of 278 current WP smokers from 8-waves of an ongoing longitudinal cohort of 8 th-9 th-graders in Lebanon. Group-based trajectory modeling was estimated to identify trajectory classes for ICD-10-ND criteria over ages11-18.

RESULTS

A group-based modeling approach yielded a four-class solution that best fit the data and reflected differences in the timing of ND onset during adolescence:no-onset of ND(43.9%), early(16.2%), mid(26.6%), and late-onset(13.3%) of ND criteria. Having a less-educated mother (adjusted odds ratio[aOR]=4.08, 95%confidence interval:1.01-16.53) and siblings who smoke WP(aOR=3.95:1.08-14.42), exposure to favorite WP-specific advertisements(aOR=3.33:1.03-10.85), and being a novelty seeker(aOR=1.12:1.02-1.23) were associated with early-onset of ND. Daily(aOR=3.48:1.08-11.23) or weekly(aOR=2.20:1.05-4.62) WP smokers (vs. monthly) and having higher stress level (aOR=1.07:1.00-1.14) were associated with mid-onset trajectory. Believing that WP smoking is not harmful to health (aOR=0.11:0.02-0.82) and spending >60 minutes on a WP smoking session(aOR=5.62:1.20-26.44) were associated with late-onset ND trajectory class.

CONCLUSIONS

Monitoring the development of ND trajectories among WP smokers may identify an individual as belonging to one of these four groups with distinct individual and socio-environmental factors, and allow the individual and healthcare providers opportunities to inform initiate on-time WP-specific tailored prevention and cessation interventions.

Perceived health risks associated with the use of tobacco and nicotine products during the COVID-19 pandemic

INTRODUCTION

The perceived health risks of tobacco products may change during the ongoing COVID-19 pandemic. This study aimed to examine the perceived risks of tobacco use on COVID-19 infection and severity, and possible COVID-related changes in perceptions of tobacco use and overall health.

METHODS

We conducted an online survey of adults in the United States in June 2020 (n=2097). The survey covered cigarettes, cigars, e-cigarettes, and hookah. We also assessed changes in the use of any of the four tobacco products. Multivariate logistic regression models were used to estimate the odds of agreeing with the perceived risks for each risk and each product, with the adjustment of demographic and COVID-19 related variables.

RESULTS

For all four tobacco products, the perceived risks to general health were slightly higher during the pandemic than before the pandemic (77% vs 79.5% for cigarettes) and the perceived risk of COVID-19 severity was larger than the perceived risk of COVID-19 infection (73.3% vs 56.2% for cigarettes). All risk measures varied with tobacco products consistently, with the risks highest for cigarettes, then cigars, followed by e-cigarettes and hookah. Females and people with higher income or education were more likely to endorse the risks of tobacco use than their counterparts. People who perceived higher risks of using cigarettes (OR=1.65; 95% CI: 1.20-2.27) and cigars (OR=1.63; 95% CI: 1.17-2.27) to COVID-19 severity were more likely to have decreased or quit their use.

CONCLUSIONS

Tobacco/nicotine use was perceived to increase the risk of COVID-19 severity and the perceived risk of tobacco/nicotine use to general health was high during the pandemic, particularly for cigarettes. The change of perceived risks appeared to be prompting harm-reducing changes in tobacco product use.

Interest in Cessation Treatment Among People Who Smoke in a Community-Based Multidisciplinary Thoracic Oncology Program

INTRODUCTION

To evaluate the need for tobacco cessation services within a multidisciplinary clinic (MDC), we surveyed patients on their smoking status, interest in quitting, and willingness to participate in a clinic-based cessation program. We further evaluated the association between interest in cessation or willingness to participate in a cessation program and overall survival (OS).

METHODS

From 2014 to 2019, all new patients with lung cancer in the MDC at Baptist Cancer Center (Memphis, TN) were administered a social history questionnaire to evaluate their demographic characteristics, smoking status, tobacco dependence, interest in quitting, and willingness to participate in a cessation program. We used chi-square tests and logistic regression to compare characteristics of those who would participate to those who would not or were unsure and Kaplan-Meier curves and Cox regression to evaluate the association between cessation interest or willingness to quit and OS.

RESULTS

Of 641 total respondents, the average age was 69 years (range: 32-95), 47% were men, 64% white, 34% black, and 17% college graduates. A total of 90% had ever smoked: 34% currently and 25% quit within the past year. Among the current smokers, 60% were very interested in quitting and 37% would participate in a cessation program. Willingness to participate in a cessation program was associated with greater interest in quitting (p < 0.0001), better OS (p = 0.02), and reduced hazard of death (hazard ratio = 0.52, 95% confidence interval: 0.30-0.88), but no other characteristics.

CONCLUSIONS

Patients with lung cancer in an MDC expressed considerable interest in tobacco cessation services; patients willing to participate in a clinic-based cessation program had improved survival.

Nicotine-naïve adolescents who live with tobacco products users, 2018 Florida Youth Tobacco Survey

OBJECTIVE

We assessed the prevalence and factors associated with living with tobacco/nicotine product users among nicotine-naïve adolescents.

METHODS

Data were from the 2018 Florida Youth Tobacco Survey that included 34,183 adolescents who were never-tobacco product users and provided information about living with tobacco/nicotine users.

RESULTS

More than a quarter of adolescents lived with a tobacco/nicotine user. Girls were more likely than boys and middle-schoolers were more likely than high-schoolers to live with someone who uses cigarettes, cigars, and poly-tobacco. Compared to non-Hispanic Whites, Hispanics were less likely to live with someone who uses cigarettes, electronic nicotine delivery systems, cigars, and poly-tobacco. Adolescents who reported currently having asthma were more likely to report living with someone who smokes cigarettes, hookah, and poly tobacco.

CONCLUSIONS

To reduce and ideally eliminate exposure to smoke/aerosol emitted from tobacco products in nicotine-naïve adolescents, individual and family-centered interventions, coupled with state-wide tobacco prevention strategies are warranted.

Natural Course of Nicotine Dependence Among Adolescent Waterpipe and Cigarette Smokers

PURPOSE

Waterpipe (WP) smoking patterns and setting can result in a unique trajectory of nicotine dependence (ND) compared with cigarette smoking. This longitudinal study compared the development of ND symptoms among adolescent WP and cigarette smokers.

METHODS

A cohort of 647 eighth and ninth graders in Lebanon were followed over 5 years. This study was based on 283 current exclusive WP and 146 current exclusive cigarette smokers. Kaplan-Meier survival analyses were conducted to evaluate 50% cumulative probability for the development of initial Hooked on Nicotine Checklist symptoms and the International Classification of Diseases, 10th revision (ICD-10) ND.

RESULTS

An initial Hooked on Nicotine Checklist symptom was endorsed by 59% of WP and 50% of cigarette smokers after smoking onset. Among those, 50% of both WP and cigarette smokers did so within 9.7 and 18.5 months, respectively. Approximately 28% of WP smokers and 22% of cigarette smokers developed ICD-10 ND. Among those, 50% of both WP and cigarette smokers did so within 15 and 22 months, respectively. The most common first to fourth ICD-10 criteria reported by WP smokers were "a strong desire to use tobacco," "difficulties in controlling tobacco taking behavior," "neglect of alternative pleasure," and "use despite harm." The most common first to fourth ICD-10 criteria reported by cigarette smokers were "a strong desire to use tobacco," "difficulties in controlling tobacco taking behavior," "withdrawal," and "tolerance".

CONCLUSIONS

Compared with adolescent cigarette smokers, initial ND symptoms and ICD-10 ND can develop sooner after starting to smoke and progress more rapidly among adolescent WP smokers. Developing, implementing, and evaluating intervention programs with adolescent WP smokers should be guided by the WP-specific trajectory of ND.

Predictors of nicotine dependence among adolescent waterpipe and cigarette smokers: A 6-year longitudinal analysis

OBJECTIVE

Identifying the factors associated with nicotine dependence (ND) is essential to prevent initiation and continued use, and to promote cessation among youth. This study aims to document the predictors of the appearance of initial ND symptoms and full ND syndrome among adolescent waterpipe (WP) and cigarette smokers.

METHODS

A 6-year longitudinal study was conducted among 8th and 9th graders from 38 schools in Lebanon. The analysis sample included exclusive-WP (n = 228) and exclusive-cigarette smokers (n = 139). Weighted Cox proportional hazards models were used to characterizing predictors of initial ND symptoms and full ND syndrome.

RESULTS

Predictors of experiencing initial ND symptoms among WP smokers included low maternal educational level, having a sibling who smoked WP, low physical activity, high body mass index (BMI), smoking initiation at a younger age. For cigarette smokers these were being male, younger, having lower BMI, having a sibling who smoked cigarettes, living in a crowded household, and smoking daily. Among WP smokers, predictors of developing full ND syndrome include being younger, believing that WP smokers have more friends, depression, high levels of impulsivity, and initiating smoking at a younger age. For cigarette smokers, predictors of full ND syndrome were being younger and initiating smoking at a younger age.

CONCLUSION

Smoking cessation and prevention interventions targeting youth should address modifiable, and tobacco use-specific factors that influence the development of ND among young WP and cigarette smokers. They also need to start at a younger age to target those most vulnerable to developing life-long addiction to tobacco products.
