Patient Survey in Medical Practices on their Visit during the SARS-CoV-2 Pandemic.

Background: Since the beginning of the SARS-CoV2 pandemic medical practices have implemented diverse protective measures to contain the pandemic, practice organization and structures were adapted. In order to get information about patients' perception of their doctors' visit during the pandemic, we conducted a patient survey in medical practices. Method(s): Cross-sectional study of 58 patients, who were interviewed in four medical practices (family physicians and specialists) in the South West of Munich from 02.04.-17.04.2020 on the following topics: "personal risk assessment", "sense of security and perception of protection measures in the practice setting", "importance of the doctor's visit" and "change of medication, nicotine consumption". By means of a questionnaire with 24 items, data were collected anonymously. Results are presented descriptively and via ANOVA as well as via linear regression. Result(s): The personal risk assessments for COVID-19-disease and for a severe course of COVID-19 were rated low moderate, independent of sex or age. Around 8% of the surveyed patients discussed their personal risk with their doctors. The sense of security in the practice setting was rated high. The rating of the protection equipment was good as well, and closely met expectations. The personal importance of the visit varied. Only 6% had considered cancelling their visit beforehand. A change of medication due to SARS-CoV-2 pandemic was not observed. Conclusion(s): The patient survey provides a snapshot of the outpatient setting from the patient's perspective in a hyperdynamic pandemic situation. Yet, due to the small study population, the results have to be interpreted with caution.Copyright © 2021, Deutscher Arzteverlag.

SMOKING AS ONE OF THE PREDICTORS OF THE SEVERITY OF THE CONDITION OF PATIENTS SUFFERING FROM A NEW CORONAVIRUS INFECTION

The relationship between smoking and the lung damage volume in patients with a confirmed new coronavirus infection diagnosis, hospitalized in a temporary infectious hospital for the treatment of patients suffering from a new coronavirus infection and community-acquired pneumonia was evaluated. This was in the Odintsovo District's Patriot Park of the Moscow region. Smoking cigarettes, both active and passive, as well as exposure to tobacco smoke on the body, are important upper and lower respiratory tract infection risk factors due to local immune response suppression. Nevertheless, data from a number of international studies indicate a significantly lower number of hospitalized smoking patients compared to nonsmokers. These indicators were investigated as the percentage and degree of lung damage, smoking history, the number of cigarettes smoked per day, and the smoker's index. In the course of the study, the data on a smaller percentage of smokers admitted to inpatient treatment were confirmed in comparison with non-smokers and smokers in the general population. There was no statistically significant difference in the volume of lung damage between smoking and non-smoking patients according to the chest organs computed tomography. At the same time, there was an increase in the volume of lung tissue damage, depending on the smoking experience. This is apparently due to the irreversible changes formation in lung tissue against a long-term smoking background. The median age of smoking patients was 56 years with a variation from 46 to 68 years. The minimum and maximum ages were 29 and 82. The median lung lesion was 32% with a variation from 23% to 39%. The minimum and maximum lung damage is 10% and 40%, respectively. A moderate correlation was found between the smoking experience and the volume of lung damage. An increase in lung damage by 0.309% should be expected with an increase in smoking experience by one full year. There was also no statistically significant difference in the number of cigarettes smoked per day and the smoker's index. All rights reserved © Eco-Vector, 2022.

Current status of tobacco use, cessation and control policy in Korea.

Background: Tobacco use is a leading cause of countless deaths and disabilities worldwide. An estimated 11 million Korean adults were still using tobacco in 2020, according to the Korea National Health and Nutrition Examination Survey. This review aims to explain the current trends in tobacco use, sales, cessation, and control policies in South Korea. Current Concepts: Heated tobacco products (HTPs), a hybrid between conventional and electronic cigarettes, were first launched in South Korea in June 2017. Advertisements stating that HTPs are odorless, tar-free, and less harmful to health have caused sales of HTPs to grow quickly over the past 5 years, such that they account for about 15% of the total tobacco market. According to national smoking rate statistics and tobacco sales trends, declines in current smoking rates have slowed and even risen in some groups, and declines in total tobacco sales have slowed but also risen again during the coronavirus 19 pandemic. In addition, the number of visitors to smoking cessation clinics decreased just after the advent of HTPs and social distancing policies triggered by the coronavirus. Nicotine replacement therapy can serve as a drug therapy for smoking cessation, or bupropion and varenicline can be prescribed. Korea's representative tobacco control policies include the tax increase policy, non-smoking area policy, cigarette pack warning picture policy, and support policy for visiting smoking cessation clinics. Discussion and Conclusion(s): There is a pressing need to reflect tobacco control policies in line with changes in tobacco user behaviors and tobacco company marketing strategies.Copyright © Korean Medical Association.

The controversial effect of smoking and nicotine in SARS-CoV-2 infection.

The effects of nicotine and cigarette smoke in many diseases, notably COVID-19 infection, are being debated more frequently. The current basic data for COVID-19 is increasing and indicating the higher risk of COVID-19 infections in smokers due to the overexpression of corresponding host receptors to viral entry. However, current multi-national epidemiological reports indicate a lower incidence of COVID-19 disease in smokers. Current data indicates that smokers are more susceptible to some diseases and more protective of some other. Interestingly, nicotine is also reported to play a dual role, being both inflammatory and anti-inflammatory. In the present study, we tried to investigate the effect of pure nicotine on various cells involved in COVID-19 infection. We followed an organ-based systematic approach to decipher the effect of nicotine in damaged organs corresponding to COVID-19 pathogenesis (12 related diseases). Considering that the effects of nicotine and cigarette smoke are different from each other, it is necessary to be careful in generalizing the effects of nicotine and cigarette to each other in the conducted researches. The generalization and the undifferentiation of nicotine from smoke is a significant bias. Moreover, different doses of nicotine stimulate different effects (dose-dependent response). In addition to further assessing the role of nicotine in COVID-19 infection and any other cases, a clever assessment of underlying diseases should also be considered to achieve a guideline for health providers and a personalized approach to treatment.

Associations of Combustible Cigarette, Electronic Cigarette, and Dual Use With COVID Infection and Severity in the U.S.: A Cross-sectional Analysis of the 2021 National Health Information Survey.

Given the potential respiratory health risks, the association of COVID infection and the use of combustible cigarettes, electronic nicotine delivery systems (ENDS), and concurrent dual use is a priority for public health. Many published reports have not accounted for known covarying factors. This study sought to calculate adjusted odds ratios for self-reported COVID infection and disease severity as a function of smoking and ENDS use, while accounting for factors known to influence COVID infection and disease severity (i.e., age, sex, race and ethnicity, socioeconomic status and educational attainment, rural or urban environment, self-reported diabetes, COPD, coronary heart disease, and obesity status). Data from the 2021 U.S. National Health Interview Survey, a cross-sectional questionnaire design, were used to calculate both unadjusted and adjusted odds ratios for self-reported COVID infection and severity of symptoms. Results indicate that combustible cigarette use is associated with a lower likelihood of self-reported COVID infection relative to non-use of tobacco products (AOR = .64; 95% CI [.55, .74]), whereas ENDS use is associated with a higher likelihood of self-reported COVID infection (AOR = 1.30; 95% CI [1.04, 1.63]). There was no significant difference in COVID infection among dual users (ENDS and combustible use) when compared with non-users. Adjusting for covarying factors did not substantially change the results. There were no significant differences in COVID disease severity between those of varying smoking status. Future research should examine the relationship between smoking status and COVID infection and disease severity utilizing longitudinal study designs and non-self-report measures of smoking status (e.g., the biomarker cotinine), COVID infection (e.g., positive tests), and disease severity (e.g., hospitalizations, ventilator assistance, mortality, and ongoing symptoms of long COVID).

Pandemic-Related Changes in the Prevalence of Early Adolescent Alcohol and Drug Use, 2020-2021: Data From a Multisite Cohort Study.

PURPOSE: Evaluate changes in early adolescent substance use from May 2020 to May 2021 during the coronavirus disease 2019 pandemic using data from a prospective nationwide cohort: the Adolescent Brain Cognitive Development Study. METHODS: In 2018-2019, 9,270 youth aged 11.5-13.0 completed a prepandemic assessment of past-month alcohol and drug use, then up to seven during-pandemic assessments between May 2020 and May 2021. We compared the prevalence of substance use among same-age youth across these eight timepoints. RESULTS: Pandemic-related decreases in the past-month prevalence of alcohol use were detectable in May 2020, grew larger over time, and remained substantial in May 2021 (0.3% vs. 3.2% prepandemic, p <.001). Pandemic-related increases in inhalant use (p = .04) and prescription drug misuse (p < .001) were detectable in May 2020, shrunk over time, and were smaller but still detectable in May 2021(0.1%-0.2% vs. 0% pre-pandemic). Pandemic-related increases in nicotine use were detectable between May 2020 and March 2021 and no longer significantly different from prepandemic levels in May 2021 (0.5% vs. 0.2% prepandemic, p = .09). There was significant heterogeneity in pandemic-related change in substance use at some timepoints, with increased rates among youth identified as Black or Hispanic or in lower-income families versus stable or decreased rates among youth identified as White or in higher-income families. DISCUSSION: Among youth ages 11.5-13.0 years old, rates of alcohol use remained dramatically reduced in May 2021 relative to prepandemic and rates of prescription drug misuse and inhalant use remained modestly increased. Differences remained despite the partial restoration of prepandemic life, raising questions about whether youth who spent early adolescence under pandemic conditions may exhibit persistently different patterns of substance use.

Alcohol, cannabis, and nicotine use have distinct associations with COVID-19 pandemic-related experiences: An exploratory Bayesian network analysis across two timepoints.

BACKGROUND: Substance use trends during the COVID-19 pandemic have been extensively documented. However, relatively less is known about the associations between pandemic-related experiences and substance use. METHOD: In July 2020 and January 2021, a broad U.S. community sample (N = 1123) completed online assessments of past month alcohol, cannabis, and nicotine use and the 92-item Epidemic-Pandemic Impacts Inventory, a multidimensional measure of pandemic-related experiences. We examined links between substance use frequency, and pandemic impact on emotional, physical, economic, and other key domains, using Bayesian Gaussian graphical networks in which edges represent significant associations between variables (referred to as nodes). Bayesian network comparison approaches were used to assess the evidence of stability (or change) in associations between the two timepoints. RESULTS: After controlling for all other nodes in the network, multiple significant edges connecting substance use nodes and pandemic-experience nodes were observed across both time points, including positive- (r range 0.07-0.23) and negative-associations (r range -0.25 to -0.11). Alcohol was positively associated with social and emotional pandemic impacts and negatively associated with economic impacts. Nicotine was positively associated with economic impact and negatively associated with social impact. Cannabis was positively associated with emotional impact. Network comparison suggested these associations were stable across the two timepoints. CONCLUSION: Alcohol, nicotine, and cannabis use had unique associations to a few specific domains among a broad range of pandemic-related experiences. Given the cross-sectional nature of these analyses with observational data, further investigation is needed to identify potential causal links.

Psychiatric Disorders During Pregnancy in Asymptomatic and Mildly Symptomatic SARS-CoV-2 Positive Women: Prevalence and Effect on Outcome

Background: The effect of psychiatric comorbidity on pregnancy outcome among SARS-CoV-2 positive women with asymptomatic and mildly symptomatic infections remains largely unknown Methods: Electronic medical records of all pregnant women who received care at Mayo Health System and tested positive for SARS-CoV-2 (RT-PCR) from March 2020 through October 2021 were reviewed Results: Among 789 patients, 34.2% (n=270) had psychiatric comorbidity. Of those, 62.2% (n=168) had depression prior to pregnancy and 5.2% (n=14) reported new onset depression during pregnancy. Anxiety diagnosis was present in 65.6% (n=177) prior to pregnancy and new onset anxiety in 4.4% (n=12). Thirteen percent of SARS-CoV-2 positive pregnant women (n=108) received a psychotropic medication during pregnancy. In addition, 6.7% (n=18) and 10.7% (n=29) of pregnant women with psychiatric comorbidity had a documented nicotine, cannabis and/ or illicit substance use during and prior to pregnancy, respectively. Asymptomatic and mildly symptomatic SARS-CoV-2 positive pregnant women with psychiatric comorbidity had significantly higher risk for cesarean delivery [35.6% vs.24.9%). Conclusion(s): In conclusion, the prevalence rates of depression, anxiety, and prescribed antidepressant medications during pregnancy among asymptomatic and mildly symptomatic SARS-CoV-2 infected women were substantially higher than average, which negatively impacted on pregnancy and neonatal outcomes.

Smoking on COVID-19 pandemic: neurobiological aspects of drug abuse in lasting stress conditions

One of the biggest global public health crisis began in Wuhan, China at the end of 2019. That emergency was the emergence of SARS-CoV-2 and the disease COVID-19, a highly transmissible acute respiratory syndrome. The pandemic declaration by the WHO in March 2020 caused the world to take on several measures to combat and contain the virus. Initially, social isolation and lockdown were the main initiatives, as there were no forms of treatment or prevention of the disease. These restrictive measures generate a change in the habit of the population that triggered serious physical and psychological impairments. One of the consequences was the increase in the use of substances of abuse and, consequently, substance use disorder, including tobacco. During the pandemic, cigarette consumption increased from 10 to 30% worldwide, whereas smoking is the main cause of preventable death and a risk factor for several diseases. Along with alcohol, nicotine has a greater addictive power than illicit drugs. Substance use disorders and COVID-19 have a synergistic effect, in this way, we seek to integrate neurochemical, cognitive and behavioral aspects that led to increased consumption and/or relapse in nicotine consumption and the used therapy.

Adolescent E-cigarette use: Rates, concerns, and policy implications

While US consumption of conventional cigarettes has declined steadily, electronic cigarettes have been the most commonly used tobacco product among adolescents since 2014, with a particular surge in use starting in 2017. The 2021 National Youth Tobacco Survey (NYTS) found that even during the COVID-19 pandemic, 2 million adolescents were current e-cigarette users. Just prior to the pandemic in 2020, one in five high school students and one in ten middle school students were using e-cigarettes every day, about the same level as in 2018 when adolescent e-cigarette use was declared an epidemic. Daily use is a strong indicator of nicotine dependence, raising concerns that e-cigarettes will hook a new generation on nicotine, including combustible cigarettes and other tobacco products. E-cigarettes are associated with a number of significant health consequences, including nicotine addiction, toxic effects of flavors, and psychological, social, and educational effects. Adolescents are especially attracted to e-cigarettes because of their youth-friendly flavors and salt-based nicotine which makes the device easier to use with less harsh throat hit, and allows users to more readily inhale large amount of nicotine. Adolescents are also attracted to the appealing designs and ability to conceal the e-cigarette devices;aggressive marketing that targets adolescents;misperceptions about the products' nicotine levels and health effects;and ease of access. Previous successful efforts to reduce tobacco use have been washed away due to the adolescent e-cigarette epidemic. This chapter discusses rates of adolescent e-cigarette use, health effects, why adolescents use e-cigarettes, and then ends with a discussion of the policy implications. © 2023 Elsevier Inc.

SARS-CoV-2 spike ectodomain targets α7 nicotinic acetylcholine receptors.

Virus entry into animal cells is initiated by attachment to target macromolecules located on host cells. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) trimeric spike glycoprotein targets host angiotensin converting enzyme 2 to gain cellular access. The SARS-CoV-2 glycoprotein contains a neurotoxin-like region that has sequence similarities to the rabies virus and the HIV glycoproteins, as well as to snake neurotoxins, which interact with nicotinic acetylcholine receptor (nAChR) subtypes via this region. Using a peptide of the neurotoxin-like region of SARS-CoV-2 (SARS-CoV-2 glycoprotein peptide [SCoV2P]), we identified that this area moderately inhibits α3ß2, α3ß4, and α4ß2 subtypes, while potentiating and inhibiting α7 nAChRs. These nAChR subtypes are found in target tissues including the nose, lung, central nervous system, and immune cells. Importantly, SCoV2P potentiates and inhibits ACh-induced α7 nAChR responses by an allosteric mechanism, with nicotine enhancing these effects. Live-cell confocal microscopy was used to confirm that SCoV2P interacts with α7 nAChRs in transfected neuronal-like N2a and human embryonic kidney 293 cells. The SARS-CoV-2 ectodomain functionally potentiates and inhibits the α7 subtype with nanomolar potency. Our functional findings identify that the α7 nAChR is a target for the SARS-CoV-2 glycoprotein, providing a new aspect to our understanding of SARS-CoV-2 and host cell interactions, in addition to disease pathogenesis.

Pandemic-related life changes and adolescent initiation of cannabis and tobacco/nicotine use.

BACKGROUND: The COVID-19 pandemic required the public to alter their daily lives drastically. For adolescents, school closures and social isolation added further challenges to a stressful stage of life, potentially increasing the likelihood of substance use initiation. This study explored the relationship between adolescent substance use initiation and negative life changes due to COVID-19. METHODS: Students from 9 high schools (N = 2478) in Los Angeles County were surveyed as 9th graders in the 2019-2020 school year and re-surveyed in 10th and 11th grades as part of an ongoing longitudinal study. Two logistic regression models were conducted to test hypotheses that negative life changes due to the COVID-19 pandemic increases the odds of initiation of both tobacco/nicotine products and cannabis products, controlling for sex, age, and race/ethnicity. RESULTS: The final analytic sample included adolescents in 10th grade who were never-users of tobacco/nicotine (N = 809) and cannabis (N = 837). The odds of initiating cannabis use increased by 6.42% for every 1 standard deviation increase in the COVID-19 negative daily life changes index [AOR: 1.063; 95% CI: 1.010, 1.121]. The association between the COVID-19 negative daily life changes index and tobacco/nicotine use initiation was not significant. DISCUSSION: Adolescents who experienced life changes due to COVID-19 were more likely to initiate cannabis use, but not tobacco/nicotine use. Results identify a need for early intervention efforts to promote effective coping skills and prevent cannabis initiation among adolescents during a wide-scale stressor, such as COVID-19.

Vaping Behavior in Young Adults During the COVID-19 Pandemic.

BACKGROUND: Electronic nicotine delivery systems (ENDS) continue to be popular among young adults. These devices are often advertised as a healthy alternative to quitting tobacco cigarettes. However, young adults represent a population who view it as a novel behavior that provides a sense of popularity, social acceptance, and desired physiologic properties. The objective of this study was to examine characteristics of vaping behavior among college students and explore possible associations between groups of vaping behavior (stopped, initiated, increased, decreased, stayed the same). METHODS: In a multi-center cross-sectional study, 656 students from University of Tampa in the United States and University of Applied Sciences in Germany (IST) were recruited to answer a 31-item online questionnaire. A chi-square test was used to evaluate associations between the groups. RESULTS: Prevalence rates indicated approximately 31% of all students were currently using ENDS. Even though more negative than positive experiences with ENDS were reported, most students stated their vaping increased during COVID-19 lockdowns. Addiction and stress relief emerged to be predictors (P < .001) of an increase in vaping, whereas social motives were not statistically significant. Living situation (P = .63) and depression (P = .10) were not significantly associated with vaping behavior. CONCLUSIONS: ENDS products continue to yield very high levels of nicotine creating addiction in young adults. Addiction counseling and evidenced-based practices should be employed at every level (individual, community, and school). Additionally, mental health counseling for students in pandemic and high-stress environments may help to combat stress in a more proactive manner than self-medicating.

Did the COVID-19 Lockdown Reduce Smoking Rate in Adolescents?

This study examined the temporal trend of smoking use and the prevalent differences in the use of different types of cigarettes for Korean adolescents before and during the COVID-19 pandemic. In Korea, all use of e-cigarettes, including regular cigarettes, is considered smoking. Since adolescents are susceptible to peer influences in risky behaviors including smoking, social distancing could affect the smoking behaviors of youth under these unusual circumstances during the pandemic. In this study, we analyzed the Korea Youth Risk Behavior Web-based Survey (KYRBW) data collected from 2018 to 2021 to examine the association between smoking status and other covariates during the COVID-19 pandemic. As a result, it was confirmed that the influence of second-hand smoke on the smoking rate decreased before and after COVID-19, which is interpreted as a result of the social distancing policy caused by the pandemic.

Correlates of smoking during COVID-19 in the LGBTQI + cancer survivor population.

PURPOSE: Stressors brought on by the pandemic may have further encouraged lesbian, gay, bisexual, transgender, queer, and intersex plus (LGBTQI +) cancer survivors to smoke. The purpose of this study is to examine factors associated with smoking among LGBTQI + cancer survivors during the pandemic. METHODS: We used a secondary data analysis of OUT: The National Cancer Survey. We conducted logistic regression analysis to examine the associations between psychological distress, binge drinking, and socio-demographic factors with ever use and current use of cigarettes, other tobacco, and nicotine products. RESULTS: Of the 1629 participants in our sample, 53% used in their lifetime and 13% reported current use. Correlates of increased ever use included being of older age (AOR = 1.02; 95% CI: 1.01, 1.03) and binge drinking (AOR = 2.47; 95% CI: 1.17, 5.20) while correlates of decreased ever use were among those with a graduate or professional degree (AOR = 0.40; 95% CI: 0.23, 0.71). Correlates of increased current use included being of Latine descent (AOR = 1.89; 95% CI: 1.07, 3.36), binge drinking (AOR = 3.18; 95% CI: 1.56, 6.48), without health insurance (AOR = 2.37; 95% CI: 1.10, 5.10), and being disabled (AOR = 1.64; 95% CI: 1.19, 2.26) while correlates of decreased current use were among cisgender women (AOR = 0.30; 95% CI: 0.12, 0.77), being of younger age (AOR = 0.98; 95% CI: 0.96, 0.99), and having a graduate or professional degree (AOR = 0.33; 95% CI: 0.15, 0.70). CONCLUSIONS: Our findings demonstrate that a proportion of LGBTQI + cancer survivors continue to smoke during the pandemic despite the increased risk involved with smoking. Furthermore, individuals with intersecting marginalized identities experience additional stressors that may have been further exacerbated by the conditions of the pandemic that encourage them to smoke. IMPLICATIONS FOR CANCER SURVIVORS: Quitting smoking after a cancer diagnosis can decrease the chances of recurrence and a new primary malignancy. In addition, practitioners and researchers should advocate towards examining and addressing systemic forms of oppression in institutions that LGBTQI + cancer survivors navigate during the pandemic.
