Background: According to World Health Organization (WHO) estimates, there are currently 1.1 billion tobacco smokers worldwide. This study follows the need for change in the increasing trend of lifestyle-related diseases and the lack of extensive studies on the pattern of smoking. Methods: In the current study, an electronic database search was conducted to identify studies that examined the impact of smoking on internal diseases from the beginning of February 2018 to the end of December 2021. After eliminating numerous articles based on their titles and abstracts, 273 articles pertinent to the study's objectives were selected. Due to the inadequacy of the target audience and the inclusion and exclusion criteria, 239 of the remaining articles were eliminated. The 44 remaining articles were examined more closely. Results: Each cigarette produces more than 7,000 chemicals. Many of these substances are toxic, and about 69 of them can cause cancer. For every 15 cigarettes you smoke, a mutation occurs in the body. Mutations are the cause of cancer. Studies have shown a clear relationship between dose and response, with a sharp increase in the risk of arterial disease in heavy smokers. In countries where approximately 30% of the population smokes, 50% of arterial disease can be attributed to smoking. Conclusion: Smoking increases the risk of cardiovascular disease (CVD) and lung disease, and leads to an increased risk of lung, throat, stomach, and bladder cancer, and many other cancers. One of the most important organs in the body that can be disrupted by smoking is the heart. [ABSTRACT FROM AUTHOR]

Cyanide anion can be found in foodstuffs, tobacco smoke and a variety of types of waters, mainly originating from anthropogenic activities. Due to its highly toxic nature, several agencies have established limits for cyanide levels in water. Additionally, monitoring cyanide levels in biological samples, such as blood and urine, is crucial for obtaining clinical information about the health condition of patients. Therefore, there is a pressing need for the development of simple, cost-effective, and reliable analytical methods capable of quantifying cyanide at low concentrations. This study presents a novel analytical method for the selective and sensitive determination of cyanide based on analyte volatilization, pre-concentration via single-drop microextraction (SDME) using a selective reagent, and colorimetric quantification using a paper-based analytical device. For this, 10 mL of a liquid sample was acidified with phosphoric acid and the generated HCN was collected using a single drop of 3 μL of a palladium dimethylglyoximate solution (Pd (DMG) 2 2−) positioned in the flask headspace using a syringe. The reaction of Pd (DMG) 2 2− leads to the formation of Pd(CN) 4 2− and the demasking of the organic ligand. After 15 min of extraction time, the reagent drop was added to a paper-based analytical device that has been previously impregnated with 3 μL of nickel chloride, resulting in the formation of a red precipitate of nickel (II) dimethylglyoximate. Digital images of the paper-based device were captured and the red channel (R) was used for quantification purposes. Under optimized conditions, the method demonstrates a suitable linear relation (r2 > 0.99) ranging from 26 to 286 μg L−1 and a limit of detection of 5 μg L−1. As a proof of concept, cyanide levels were quantified in water and urine samples using this method. The proposed approach offers high sensitivity and selectivity while requiring only a small volume of reagents. Furthermore, it exhibits a high degree of portability for in-situ applications. A selective and sensitive method for the determination of cyanide using HS-SDEM. [Display omitted] • Cyanide in liquid samples was determined by combining HS-SDME and digital image analysis. • Colorimetric reaction is performed on a microfluidic paper-based analytical device. • The reagent is easy to prepare and highly selective for cyanide. • Under optimized conditions, a limit of detection of 5 μg L-1 was achieved. • The point-of-care device is suitable for cyanide determination in water and urine samples.

Abstract Environmental pollution due to various elements is increasing all across the planet owing to their use in industrial processes. The tobacco plants and the vegetables used in the manufacturing of smoking paper may accumulate these elements from the environment. Thus, tobacco and smoking paper may be relevant contributors among the content of elements in cigarettes, including some emerging pollutants such as rare earth elements (REEs). Thirty-two elements related to hi-tech industrial processes were analyzed in tobacco, rolling paper, and filters (n = 257 samples) by ICP-MS. A variety of industrial brands and "roll-your-own" cigarette papers were considered. The potential maximum daily exposure to these elements by a hypothetical heavy smoker was calculated for each type of cigarette. We found significant differences in the levels of most elements, both in the tobacco and in the paper. Black tobacco cigarettes contained the maximum levels. We found that the paper used in roll-your-own cigarettes may significantly modify their concentration of elements. Fast-burning, bleached, and flavored papers also contribute to higher levels of these pollutants. Thus, the differences in theoretical exposure depending on the type of cigarette consumed–either branded or hand-rolled–may be very striking, of up to 35–40 times. In addition to the number of cigarettes consumed per day, it is necessary to consider the type of cigarette consumed to assess the risk of exposure to toxic elements. Tobacco paper is a prominent source of exposure to toxic elements. Cigarette smoke is another source of exposure to emerging contaminants such as REE. Highlights • The type of cigarettes consumed influences the exposure to toxic elements. • Black tobacco cigarettes contain the highest concentrations of toxic elements. • The rolling paper may be a major contributor to the concentration of toxic elements released. • Cigarette consumption represents an additional source of exposure to rare earth elements.

Aim: To assess the prevalence of non‐communicable disease risk factors among the nursing staff and educate them on prevention. Background: Nursing staff is integral to the Indian community healthcare systems. Recent studies report a high prevalence of non‐communicable diseases in Indian nursing staff. Therefore, data on the prevalence of non‐communicable disease risk factors among nursing staff are crucial for education on prevention. Design: A cross‐sectional digital survey‐based study. Method: We invited 4435 nursing staff to attend our online survey. We used a customized questionnaire for data collection, including a digitized version of the Community‐Based Assessment Checklist form. A score of >4 was considered high risk and warranted screening. Result: Among 682 nursing staff who attended, 70% had never undergone screening for non‐communicable diseases. The prevalence of non‐communicable disease risk factors was significantly higher in male nursing staff. In addition, logistic regression analysis showed that age, tobacco and alcohol use, increased waist circumference, physical inactivity and family history of non‐communicable diseases were significant risk factors among nursing staff. Conclusion: The study findings suggest that the nursing staff have suboptimal self‐health concerns on non‐communicable diseases. This situation warrants continued medical education, awareness campaigns on adopting a healthy lifestyle and health promotion. Summary statement: What is already known about this topic? The prevalence of non‐communicable diseases (NCDs) among Indian nursing staff is a growing concern, underscoring the need for comprehensive research and targeted interventions.Despite the significant health risks faced by this demographic, there is a notable lack of data on NCD risk factors specific to Indian nursing professionals. What this paper adds? This paper adds information on the prevalence of NCD risk factors chiefly among nursing staff in the Delhi National Capital Region.Male nursing staff have particularly high NCD risk factors. The implications of this paper: Findings may help develop routine screening programmes for nursing staff, continued nursing education and good, safe nursing practice. [ABSTRACT FROM AUTHOR]

Aim: To explore the association between nurse education levels and patient‐related factors with hypertension self‐care. Background: Although self‐care development is recognized as a healthcare provider–patient encounter, the attribution of nurse education level to hypertension self‐care is not well addressed. Design: A cross‐sectional study. Methods: Hypertensive patients from 15 primary care facilities were sampled, and self‐care was assessed using the Self‐Care of Hypertension Inventory version 2.0, with standardized scores ≥70 indicating adequate self‐care. Data on patient‐related factors were obtained from electronic health records, self‐reports and laboratory tests, while nurse education levels were categorized as standard (baccalaureate‐prepared) or higher (post‐baccalaureate specialty). Results: A total of 1493 participants were included in this study, with a median age of 66 years and 77.7% being female. Approximately 10% of participants had adequate self‐care, and 66% received care from higher educated nurses. The study showed the relation between nurse education levels and the self‐care of the patients. Adequate hypertension self‐care was significantly associated with higher educated nurse providers and patient‐related factors, including intermediate to higher education, non‐overweight/obese and the absence of age‐related comorbidities. Conclusions: Hypertensive patients who had been provided care by higher educated nurses and their favourable sociodemographic, lower cardiometabolic risk and no concomitant disease were more likely to demonstrate adequate self‐care. Summary statement: What is already known about this topic? Improving hypertension self‐care requires attention to both patient‐related and healthcare‐related factors.Clinical trial studies have established the effectiveness of nurse‐enhanced hypertension self‐care.There is currently a lack of evidence regarding the impact of nurse‐related factors, such as nurse education level, on hypertension outcomes in routine primary care practice and observational studies.What this paper adds? We confirmed that patient‐related factors, such as having intermediate to higher education, being non‐overweight/obese and not having aging‐related comorbidities, were associated with better hypertension self‐care.Patients who received care from higher educated nurses demonstrated better hypertension self‐care.The implications of this paper: To enhance hypertension self‐care, clinicians should prioritize individuals who have low levels of education, are overweight/obese and have aging‐related comorbidities.Preparing nurses with advanced competence through higher education could be a viable approach to improving hypertension outcomes in primary care settings.

Aim: This study aimed to determine the knowledge, attitudes, and practices of male nurses towards human papillomavirus (HPV) and HPV vaccination and to examine whether knowledge about the HPV vaccine affects attitudes and beliefs about HPV vaccines. Background: HPV is responsible for ≈5% of all cancers worldwide. Therefore, vaccination against HPV is recommended to prevent HPV infections and HPV‐related cancers in men and women. Methods: The study group included 383 male nurses who were asked to complete online questionnaires. The data were collected using the following tools: a sociodeomographical characteristics form, the Human Papillomavirus Knowledge Scale (HPVKS), and The Carolina HPV Immunization Attitudes and Beliefs Scale (CHIAS). Results: It was determined that the general HPV knowledge of the male nurses participating in the study was at a moderate level, but their knowledge of HPV screening test, HPV vaccination, and current HPV vaccination programmes were at a low level. Male nurses' HPV vaccination rates were relatively low, and most of them did not intend to be vaccinated. In addition, CHIAS Attitudes and Beliefs scores of the male nurses were at an average level and HPV knowledge affected the attitudes and beliefs of the nurses. Conclusion: These results demonstrate an opportunity to improve information and awareness about HPV and vaccines by nursing education. Summary statement: What is already known about the topic? Although HPV vaccination is recommended to prevent HPV infections and HPV‐related cancers in men and women, vaccination rates are far behind the target, especially for men. What this paper adds? Findings showed that male nurses' HPV vaccination rates were relatively low.Male nurses' knowledge about HPV and HPV vaccine was not sufficient.HPV knowledge affected the attitudes and beliefs of these male nurses. The implications of this paper: Nurses need to be aware of the HPV vaccine during their undergraduate education. [ABSTRACT FROM AUTHOR]

The effects of tobacco on human health have been widely investigated and documented However, there are not too many specific reports on the potential risk associated to the presence of metals in the paper employed for cigarettes fabrication Even more, there is a lack of national and international norms in this respect. Otherwise, in the literature INAA appears as the unique method for wrapping paper analysis. Therefore, without a nuclear reactor available at the National University of Mexico (UNAM), EDXRF was selected with the aim to explore the possibility to apply this method, instead of INAA, to the analysis of wrapping paper assuming this task, at the beginning, as a supplement to a previous research which was recently presented (2005).1 The analytical work was developed on the wrapping paper of eight of the most known marks of cigarettes in Mexico, in two non-destructive stages: a first survey, by the classical technique of energy dispersive X-ray fluorescence (EDXRF), used a 1 11 GB qradiation source of 238Pu and a SiLi detector. In the absence of standard reference materials for cigarette’s paper, the SRM-1832 and 1833 were required for calibration, a fiberglass air filter was used as a secondary standard. The second stage was performed in a spectrometer TX-2000, anode of Mo, quantification software EDXRF32 (fundamental parameters). This paper presents a comparison of the obtained values with those found in the literature. The results show that the EDXRF method, in the Mo tube version, has the adequate precision and detection limits for the analysis of wrapping paper. [ABSTRACT FROM AUTHOR]

An essay is presented on the subject of cigarette smoking among U.S. laborers in factories, corporate spying on workers, and the social culture of shopfloors in the U.S. during the 20th century. It examines the records of Erie, Pennsylvania, paper manufacturer Hammermill Paper Company concerning employee cigarette consumption, how employees attempted to evade corporate surveillance of their smoking, and labor relations in the U.S.

Conceptualizing tobacco dependence as a chronic relapsing condition suggests the need to use analytic strategies that reflect that premise. However, clinical trials for smoking cessation typically define the primary endpoint as a measure of abstinence at a single timepoint distal to the intervention, typically 3–12 months. This reinforces the concept of tobacco outcomes as a dichotomous state—one is, or is not, abstinent. Fortunately, there are several approaches available to handle longitudinal data that reflect the relapsing and remitting nature of tobacco use during treatment studies. In this paper, sponsored by the Society for Research on Nicotine and Tobacco's Treatment Research Network, we present an introductory overview of these techniques and their application in smoking cessation clinical trials. Topics discussed include models to examine abstinence outcomes (eg, trajectory models of abstinence, models for transitions in smoking behavior, models for time to event), models that examine reductions in tobacco use, and models to examine joint outcomes (eg, examining changes in the use of more than one tobacco product). Finally, we discuss three additional relevant topics (ie, heterogeneity of effects, handling missing data, and power and sample size) and provide summary information about the type of model that can be used based on the type of data collected and the focus of the study. We encourage investigators to familiarize themselves with these techniques and use them in the analysis of data from clinical trials of smoking cessation treatment. Implications Clinical trials of tobacco dependence treatment typically measure abstinence 3–12 months after participant enrollment. However, because smoking is a chronic relapsing condition, these measures of intervention success may not accurately reflect the common trajectories of tobacco abstinence and relapse. Several analytical techniques facilitate this type of outcome modeling. This paper is meant to be an introduction to these concepts and techniques to the global nicotine and tobacco research community including which techniques can be used for different research questions with visual summaries of which types of models can be used for different types of data and research questions.

Objective: To distil the main findings from published papers on mortality in three cohorts involving over 27,000 adults, recruited in Scotland between 1965 and 1976 and followed up ever since. Method: We read and summarized 48 peer-reviewed papers about all-cause and cause-specific mortality in these cohorts, published between 1978 and 2013. Results: Mortality rates were substantially higher among cigarette smokers in all social classes and both genders. Exposure to second-hand smoke was also damaging. Exposure to higher levels of black smoke pollution was associated with higher mortality. After smoking, diminished lung function was the risk factor most strongly related to higher mortality, even among never-smokers. On average, female mortality rates were much lower than male but the same risk factors were predictors of mortality. Mortality rates were highest among men whose paternal, own first and most recent jobs were manual. Specific causes of death were associated with different life stages. Upward and downward social mobility conferred intermediate mortality rates. Low childhood cognitive ability was strongly associated with low social class in adulthood and higher mortality before age 65 years. There was no evidence that daily stress contributed to higher mortality among people in lower social positions. Men in manual occupations with fathers in manual occupations, who smoked and drank >14 units of alcohol a week had cardiovascular disease mortality rates 4.5 times higher than non-manual men with non-manual fathers, who neither smoked nor drank >14 units. Men who were obese and drank >14 units of alcohol per day had a mortality rate due to liver disease 19 times that of normal or underweight non-drinkers. Among women who never smoked, mortality rates were highest in severely obese women in the lowest occupational classes. Conclusion: These studies highlight the cumulative effect of adverse exposures throughout life, the complex interplay between social circumstances, culture and individual capabilities, and the damaging effects of smoking, air pollution, alcohol and obesity.

Background: In recent years, electronic cigarettes (ECs) have been heavily advertised as an alternative smoking device as well as a possible cessation method. We aimed to review all published scientific literature pertaining to ECs and to present a simple conclusion about their effects for quitting smoking and respiratory health. Methods: This was a cross-sectional study with a search of PubMed, limited to English publications upto September 2014. The total number of papers which had ECs in its title and their conclusions positive or negative regarding ECs effects were computed. The number of negative papers was subtracted from the number of positive ones to make a score. Results: Of the 149 articles, 137 (91.9%) were accessible, of which 68 did not have inclusion criteria. In the 69 remaining articles, 24 studies supported ECs and 45 considered these to be harmful. Finally, based on this evidence, the score of ECs (computed result with positive minus negative) was −21. Conclusion: Evidence to suggest that ECs may be effective and advisable for quitting smoking or a safe alternative for smoking is lacking and may instead harm the respiratory system. However, further studies are needed. [ABSTRACT FROM AUTHOR]

Two cigarette papers with the same basis weight and permeability but different pore structures were prepared. The effect of the pore structure after pyrolysis on CO yield in mainstream smoke was investigated by heating the papers to 250 °C. Diffusivity, permeability, pore size distribution, and pore volume of the cigarette papers before and after heating were also measured. The pore structures of the completely pyrolyzed cigarette paper in the burning cone and the incompletely pyrolyzed area near the char line were elucidated. CO yield in mainstream and sidestream smoke and the temperature distribution of the burning cone were evaluated. Diffusivity and permeability of the cigarette papers after heating were significantly higher than of the control sample after heating. The volume of pores in the cigarette paper with a size of 0.1-8.0 μm was increased, which decreased CO content in mainstream smoke. An increase in the amount of micropores facilitates CO diffusion from mainstream to sidestream smoke. [ABSTRACT FROM AUTHOR]

Background: In this paper, a rare case is reported, where the patient is a 74-year-old man. He suffered from recurrent pneumothorax within half a year and experienced a relapse after receiving conservative treatments. Case presentation: Diagnostic workup revealed a cystic lesion in the right middle lobe, which has been interpreted as a bulla during the initial chest CT scan. Due to recurrent pneumothorax and poor response to the conservative treatments, the patient underwent bullectomy and pleurodesis. The pathology showed that the wall of the cystic lesion was invasive adenocarcinoma. Conclusions: This case highlights the importance of monitoring cystic lesions in the lungs, especially in patients with a history of smoking and emphysema. [ABSTRACT FROM AUTHOR]

Introduction: The recent approval of Dupilumab has profoundly revolutionized the management of patients affected by severe and recalcitrant Chronic Rhinosinusitis with Nasal Polyps (CRSwNP). However, a review that summarizes the results of real-life studies and compares them to phase 3 studies SINUS-24 and 52 is still lacking. Materials and methods: A search of all real-life studies published from 2019 to 2023 was performed. Patients characteristics at baseline and 6 and 12 months after starting Dupilumab were extracted and compared to those from phase 3 trials: age, sex, smoking habits, comorbid asthma and aspirin-exacerbated respiratory disease (AERD), previous endoscopic sinus surgery (ESS), hematic eosinophils and total IgE, NasalAQ2 Polyps Score (NPS), smell, SNOT-22, adverse events (AEs), and response to treatment. Results: 15 papers were included with an overall number of 1658 patients. A higher rate of comorbidities and previous ESS was found in patients from real-life studies. In addition, they had worse smell and SNOT-22 at baseline compared to patients from SINUS-24 and 52. Comorbid and post-ESS patients tended to have a faster NPS and SNOT-22 improvement, although the absolute values were not clinically relevant. A more extensive surgery and a number of ESS ≥ 2 were related to worse olfactory outcomes, probably due to iatrogenic damage. No correlation was found between hematic eosinophils and outcomes. AEs were reported by 12.4% of patients and 2.2% had to discontinue dupilumab. Weight gain was an emergent AE (0.8%), probably related to the restored sense of smell and taste. Non-responders were 3.5% and they were switched to systemic steroid, ESS, or another biologic. Conclusion: Despite some differences in prescription criteria between countries, dupilumab was demonstrated to be effective even in the real-life scenario. However, emerging AEs and possible unknown long-term AEs of a likely lifelong therapy should be considered. [ABSTRACT FROM AUTHOR]

Background: Cannabis use is associated with an increased risk of coronary heart disease (CHD), including angina pectoris (AP), and myocardial infarction (MI). However, it is not clear whether cannabis use is an independent risk factor of AP and/or MI, because cannabis is often smoked together with tobacco. We investigated whether cannabis is an independent risk factor of MI and whether this risk is similar in cannabis smokers, cannabis vapers, and those who use cannabis edibles. Methods: A systematic review was performed, according to the PRISMA guidelines and using Medline (PubMed), Embase, and Google Scholar as databases. Results: Twenty-two eligible papers were identified. After adjustment for concurrent tobacco use, cannabis smoking remained significantly associated with incidents of MI, with aORs ranging between 1.03 and 5.24, and particularly high aORs in the younger age group. In never-tobacco smokers, frequent cannabis smoking was also associated with a significant MI risk (aOR = 1.88). Frequent and current cannabis use in any form other than smoking (e.g., vaping, but mostly ingestion) was not associated with a significantly increased cardiovascular risk (frequent use: aOR = 1.00 ns; current use: aOR = 1.31 ns). Conclusions: Like tobacco smoking, cannabis smoking may independently provoke MI. Vaping and ingestion of cannabis might be less harmful, probably because absence of combustion prevents exposure to certain toxins in cannabis smoke, including carbon monoxide.

Simple Summary: Oral cancer affects the mouth and throat areas. It is a major cause of death for older people in developed countries. This review looked at how living in rural areas influences oral cancer trends in these countries. The studies from these countries showed increasing rates of oral cancer in rural areas of the US, Australia, Canada, and Europe. Older people are more affected by these cancers than younger groups. The main risk factors are tobacco use, alcohol consumption, and HPV infections. People in rural areas often do not know much about HPV-related cancers. They also tend to use more tobacco and alcohol than city dwellers. Even in developed countries, living in rural areas can lead to shorter lifespans for oral cancer patients. This is mainly because it is harder for them to access specialized cancer treatment centres and advanced medical care. In summary, where people live can significantly impact their chances of surviving oral cancer, even in wealthy nations. Oral cancer is the general term used to describe cancers of the oral cavity and oropharyngeal region. These cancers are one of the leading causes of death in elderly residents within the Organisation for Economic Co-operation and Development (OECD) member countries in the 21st century. This scoping review was carried out to assess the influence of rurality on oral cancer trends and patterns among OECD member countries. Four online databases (Medline, PubMed, Scopus, and CINAHL) were searched for studies that reported on oral cancer trends in rural and remote areas in OECD member countries. A total of 1143 articles were obtained initially; among them, 995 papers were screened to include 18 articles for this scoping review. Studies have reported increasing incidence and prevalence in the United States, Australia, Canada, and European countries wherein risk factors such as tobacco, alcohol, and human papilloma virus (HPV) infections were associated with oral and oropharyngeal cancers. Awareness among people living in rural areas about HPV-related cancers was very low, while rates of tobacco and alcohol abuse were noted to be rising more rapidly than among their urban counterparts. Furthermore, the ageing population was most affected compared to the younger age groups of people with oral and oropharyngeal cancer that are prevalent in these regions. Overall, despite living in developed countries, rurality was noted to be a significant factor in the lower life expectancy of oral cancer patients, mainly due to the limited accessibility to tertiary cancer care centres and advanced medical care.

Introduction: Tobacco use is the major preventable cause of premature death worldwide, responsible for about 8 million deaths per year, mostly in low- and middle-income countries, such as Morocco. Adolescents' tobacco use is a matter of concern, because early initiation increases the risk of becoming a lifelong user. There exists a notable gap in the synthesis of evidence concerning tobacco use among Moroccan adolescents. Thus, the purpose of this study was to provide a comprehensive view of the prevalence of tobacco products' use and associated factors among adolescents in Morocco. Methods: We systematically searched PubMed, Scopus, Web of Science and ScienceDirect for relevant studies reporting prevalence rates of tobacco products' use among Moroccan adolescents, published until June 2024, using inclusion and exclusion criteria in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Additional searches were completed on other sources to reach unpublished reports. The Joanna Briggs Institute Critical Appraisal Checklist was used to assess the quality of included studies. Results: After the final screening, 22 papers met the inclusion criteria. Life-time prevalence of tobacco use ranged from 7.8% to 20.4% for cigarettes smoking, from 10.6% to 21.9% for waterpipe, from 7.9% to 9.1% for chewing tobacco and from 9.2% to 12.4% for snuff. The last 12-month prevalence of cigarette smoking was comprised between 6.9% and 10.8%. As for the prevalence of current use, ranges of (1.8%-16.4%) and (4.9%-8.4%) were noted for cigarettes and waterpipe, respectively. The most commonly highlighted risk factors for tobacco use included male sex, older age, having friends or family members who use tobacco and low perception of risk associated with tobacco use. Conclusion: Our findings reveal an alarming situation of tobacco use among Moroccan adolescents. Therefore, it is crucial that all stakeholders engage in concerted efforts to develop and implement evidence-based preventive interventions among early adolescents. [ABSTRACT FROM AUTHOR]

Introduction: There is growing scientific and policy recognition that optimising health before a potential pregnancy (preconception health) improves reproductive outcomes and the lifelong health of future children. However, public awareness on this topic is low. We conducted a public consultation to develop language recommendations and identify and prioritise approaches to inform research and improve public awareness of preconception health. Methods: A public consultation was undertaken with people of any gender aged 18–50 years living in the United Kingdom who were not currently expecting a child. Public contributors were recruited through patient and public involvement, community and support groups, an existing cohort study, and an LGBTQ+ charity. An initial round of online group discussions (February/March 2021) explored public contributors' knowledge of preconception health, their recommendations for appropriate language, and ideas about public health approaches. In a subsequent discussion round (May 2021), language recommendations were refined and suggested approaches prioritised. Discussions were summarised based on notes taken by two researchers. Results: Fifty‐four people joined the initial discussion round (66% women, 21% men, 13% nonbinary or transgender; 55% aged 18–30 years, 30% 31–40 years, 15% 41–50 years). Of these, 36 people (67%) participated in the subsequent round. Very few had heard the term 'preconception health', understood what it means, or why and for whom it is important. They recommended avoiding unfamiliar terms without further explanation (e.g., preconception health, medical terms), using language that is positive, encouraging and gender‐sensitive where possible, and using messages that are specific, nonjudgmental and realistic. The phrases 'health and well‐being during the childbearing years', 'health and well‐being before pregnancy and parenthood' and 'planning for parenthood' resonated with most public contributors. School‐based education, social media campaigns and the National Health Service emerged as priority approaches/settings for raising awareness. Conclusion: This public consultation produced recommendations from a diverse group of people of reproductive age in the United Kingdom to improve language and prioritise approaches that increase public understanding of preconception health in ways that are relevant and appropriate to them. This should begin in schools and will require adaptation of curricula, alongside co‐development of public awareness campaigns and guidance for healthcare professionals. Patient or Public Contribution: This public consultation included a diverse group of members of the public. They were not involved in the original design of the project, but following the initial round of online group discussions, they contributed to the interpretation and refinement of the emerging concepts in a subsequent round of group meetings. After the consultation activity, public contributors formed a Public Advisory Group and have subsequently been involved in other studies on the same topic. Two public contributors (E.R. and F.F.) provided critical input in the preparation and revision of this manuscript and are co‐authors of the paper. [ABSTRACT FROM AUTHOR]

Background High-risk human papillomavirus (HR-HPV) is a known cause of cervical cancer (CC). Latvia has a high incidence of CC compared with the average incidence in the European Union. This study aims to fill the data gap on the HR-HPV burden in Latvia, providing information on its prevalence and associated factors. Methods The cross-sectional study was conducted from February 2021 to April 2022. Participants 25–70 years old visiting a general practitioner (general population) or those referred to a colposcopy clinic with changes in their cervical cytology (colposcopy population) collected vaginal self-sample and completed a paper-based questionnaire. Samples were analyzed with Cobas 6800 System (Roche) for HPV16, HPV18 and other HR-HPV (HPV31/33/35/39/45/51/52/56/58/59/66/68). Descriptive statistics for categorical variables were performed. The Chi-square test was used to determine for the statistical significance of differences in the proportions of the dependent variable between subgroups of the independent variable. Univariate and multivariate binary logistic regression were used to identify factors associated with positive HR-HPV status. Results were considered statistically significant at P  < 0.05. Results A total of 1274 participants provided a valid sample. The prevalence of any HR-HPV infection was 66.8% in the colposcopy group and 11.0% in the general population. Factors associated with positive HR-HPV status were marital status single/divorced/widowed (vs. married/cohabiting) [adjusted OR (aOR) 2.6; P  = 0.003], higher number of lifetime sex partners [aOR 5.1 (P  < 0.001) and 4.0 (P  = 0.001)] for six or more and three to five partners in the general population; in the colposcopy group, the statistical significance remained only for Latvian ethnicity (vs. other) (aOR 1.8; P  = 0.008) and current smoking (vs. never) (aOR 1.9; P  = 0.01). Conclusion We documented a comparison to European Union HR-HPV infection burden in Latvia. Any HR-HPV positivity was significantly associated with sexual and other health behavior.

Monitoring respiratory variables can provide valuable information for clinical applications and sport activities. Paper-based wearable respiration monitoring systems have great advantages and potential, they are low-cost, easily disposable, non-invasive and can provide real-time, reliable data. Despite some examples presented for exhaled breath analysis using paper-based sensors exist, none of them have been validated yet in a study involving many patients. In this work, we present a novel paper-based platform for exhaled breath sensors and validate it on 101 subjects including 41 patients to demonstrate its clinical applicability. By using the paper-based wearable capacitive sensors, we collected respiration data from different groups of people, namely, smokers, non-smokers and patients diagnosed with pneumonia, or chronic obstructive pulmonary disease (COPD). The change in humidity during inhale and exhale was converted to capacitance change and thus an electrical signal was obtained. The electrical signal was transmitted to a nearby computer and capacitance versus time data was post-processed. Four ratio parameters were defined on the recorded data; area, rate, maximum amplitude, and average maximum-minimum difference, all of which were compared between deep breathing and normal breathing. The collected data was statistically analyzed, and the humidity changes were compared among different groups. The results show that the developed sensor and the proposed analysis method can be used to detect the humidity changes in breathing, and to differentiate between smokers and non-smokers, and between non-smokers and patients with pulmonary disease. [Display omitted] • An ultra-low-cost, paper-based wearable system was developed for humidity measurements and respiration monitoring. • The developed system was used to collect data from 101 volunteers including 41 patients. • The paper-based sensor has capability to produce meaningful data to distinguish smokers, nonsmokers, and patients. • Humidity measurements have potential for clinical applications.

Background: Validated Internet-based screening tools for cannabis use and abuse are needed. The present study aimed to establish equivalence between the previously validated Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) as a paper-and-pencil (PaP)-administered questionnaire and its online use. Methods: Two groups of cannabis users took part in this study and the results were analyzed using structural equation modeling. One group consisted of 150 participants and was assessed with the ASSIST PaP questionnaire in a face-to-face interview (the PaP group). They were recruited from three settings: a primary health care outpatient clinic, a general psychiatric facility, and an ambulatory specialized addiction treatment facility. The other group (the Web group) comprised 1382 persons who answered the online version of the same questionnaire. This sample was drawn from people who naturalistically visited a website dedicated to helping people with cannabis addiction. Results: The internal consistency was good for the online questionnaire (0.74) and high for the already validated PaP questionnaire (0.91). The Web group, however, had higher scores on cannabis use than did the PaP group. The results show support for configural invariance, meaning that the one-factor structure was preserved across groups, although measurement equivalence between these two survey modes was not achieved. However, when the Web group was split into two random subsamples, measurement invariance was demonstrated between them by cross-validation. Conclusions: Measurement equivalence was not achieved between the two survey modes. Nonetheless, subanalyses of the Web group demonstrated that the cannabis screening questions of the ASSIST can be used for online screening. Differences in ASSIST scores between samples may be due to the sensitive nature of the information surveyed, with possible underreporting in face-to-face interviews, or to the different characteristics of the Web group because of the specialized nature of the website.

OBJECTIVES: This paper used national survey data to investigate 'hardcore' smoking as predicted by the 'hardening hypothesis', and to examine the relationship between 'hardcore' smoking and socioeconomic status (SES). METHODS: Analyses were performed using data from four waves of the Australian National Drug Strategy Household Survey between 2001 and 2010, a large national survey with a sample size of approximately 24 000 participants per wave. The primary outcome variable was 'hardcore' smoking, comprised of the variables: 'no quit attempt in past 12 months'; 'no plan to quit'; and smoking more than 15 cigarettes per day. The main predictor variables used were SES assessed by the Socio-Economic Indexes for Areas (SEIFA), and survey wave. Other sociodemographic variables were also examined. RESULTS: Overall, 'hardcore' smoking remained stable from 2001 to 2010. However, 'hardcore' smoking declined among high-SES smokers (from 1.8% to 1.0%), but not among low-SES smokers (around 3.4%). 'Hardcore' smoking was strongly associated with SEIFA quintile (p<0.001). There was a significant interaction effect between top and bottom SEIFA quintiles and wave (p=0.025), with a decline in 'hardcore' smoking measures over the four waves among those in the top two SEIFA quintiles, with odds in 2010 of 0.39 (95% CI 0.17 to 0.87; p=0.012), down from 0.64 (95% CI 0.50 to 0.82; p<0.001) in 2001, while 'hardcore' smoking remained stable among those in the bottom two SEIFA quintiles. CONCLUSIONS: The results from high SES smokers suggest 'hardcore' smokers are able to quit, but outcomes among low-SES smokers are less encouraging. [ABSTRACT FROM AUTHOR]

Introduction Subjective experience of e-cigarettes may be an important factor in helping people who use combustible cigarettes switch completely to e-cigarettes to reduce harm from smoking. This paper describes a novel two-stage analysis using pleasure and satisfaction responses from ecological momentary assessments (EMA) of both cigarette and e-cigarette use to predict future cigarette and e-cigarette tobacco use. Aims and Methods This observational study included adult users of cigarettes and e-cigarettes who provided 7 days of EMA, capturing cigarette and e-cigarette use, followed by biweekly reports of cigarette and e-cigarette use over 1 year. Participants were 279 adults who provided both cigarette and e-cigarette responses during the EMA. We employed a two-stage analytic approach in which EMA data were used to predict subsequent levels of cigarette and e-cigarette use. In the first stage, EMA responses to cigarette and e-cigarette events were modeled via a mixed-effects location scale model to yield summaries of participants' means and variability on event-related ratings of pleasure and satisfaction. These EMA summaries served as predictors in the second stage analysis of the biweekly post-EMA longitudinal cigarette and e-cigarette use data. Results EMA pleasure and satisfaction ratings were similar for both products and predicted both longitudinal cigarette and e-cigarette use, even after controlling for baseline cigarette and e-cigarette dependence. Relatively higher levels of satisfaction with e-cigarettes were associated with greater decreases in cigarette use over time. Conclusions Pleasure and satisfaction are important predictors of subsequent cigarette and e-cigarette use. Implications Experienced subjective pleasure and satisfaction from e-cigarettes relative to cigarettes may be an important factor in helping individuals who smoke to switch completely to e-cigarettes as a harm reduction approach. In order to help sustain complete product switching and reduce dual use or relapse to smoking, e-cigarettes may need to deliver more satisfaction to the user compared to that experienced from cigarettes.

Identifying tobacco use status is essential to address use and provide resources to help patients quit. Being able to collect this information in an electronic format will become increasingly important, as the Centers for Medicare and Medicaid Services has included the assessment of tobacco use as part of its Stage 1 Meaningful Use criteria. The objective was to compare the accuracy of online vs. paper assessment methods to ascertain cigarette smoking status using a face-to-face structured interview as the gold standard. This was a retrospective analysis of a stratified opportunity sample of consecutive patients, reporting in 2010 for a periodic health evaluation, who completed either a scannable paper-based form or an online questionnaire and underwent a standardized rooming interview. Compared with face-to-face structured interview, the overall observed agreement and kappa coefficient for both methods combined (paper and online) were 97.7% and 0.69 (95% confidence interval (CI) 0.51-0.86) . For the online form they were 97.4% and 0.61 (95% CI 0.33-0.90), and for the paper form they were 97.9% and 0.75 (95% CI 0.54-0.96). There was no statistically significant difference in agreement between the online and paper-based methods ( P=0.76) compared with a face-to-face structured interview. Online assessment of tobacco use status is as accurate as a paper questionnaire, and both methods have greater than 97% observed agreement with a face-to-face structured interview. The use of online assessment of tobacco use status has several advantages and more widespread use should be explored. ( Population Health Management 2014;17:185-189) [ABSTRACT FROM AUTHOR]

Background The US Food and Drug Administration has established a policy of substantially discounting the health benefits of reduced smoking in its evaluation of proposed regulations because of the cost to smokers of the supposed lost pleasure they suffer by no longer smoking. This study used data from nine countries of the former Soviet Union (fSU) to explore this association in a setting characterised by high rates of (male) smoking and smoking-related mortality. Methods Data came from a cross-sectional populationbased study undertaken in 2010/2011 in Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia and Ukraine. Information was collected from 18 000 respondents aged ≥18 on smoking status (never, ex-smoking and current smoking), cessation attempts and nicotine dependence. The association between these variables and self-reported happiness was examined using ordered probit regression analysis. Results In a pooled country analysis, never smokers and ex-smokers were both significantly happier than current smokers. Smokers with higher levels of nicotine dependence were significantly less happy than those with a low level of dependence. Conclusions This study contradicts the idea that smoking is associated with greater happiness. Moreover, of relevance for policy in the fSU countries, given the lack of public knowledge about the detrimental effects of smoking on health but widespread desire to quit reported in recent research, the finding that smoking is associated with lower levels of happiness should be incorporated in future public health efforts to help encourage smokers to quit by highlighting that smoking cessation may result in better physical and emotional health.

Objectives Exposure of adults to secondhand smoke (SHS) has immediate adverse effects on the cardiovascular system and causes coronary heart disease. The current study evaluated brief self-report screening measures for accurately identifying adult cardiology patients with clinically significant levels of SHS exposure in need of intervention. Design and setting A cross-sectional study conducted in a university-affiliated cardiology clinic and cardiology inpatient service. Patients Participants were 118 non-smoking patients (59% male, mean age=63.6 years, SD=16.8) seeking cardiology services. Main outcome measures Serum cotinine levels and self-reported SHS exposure in the past 24 h and 7 days on 13 adult secondhand exposure to smoke (ASHES) items. Results A single item assessment of SHS exposure in one’s own home in the past 7 days was significantly correlated with serum cotinine levels (r=0.41, p<0.001) with sensitivity ≥75%, specificity >85% and correct classification rates >85% at cotinine cut-off points of >0.215 and >0.80 ng/mL. The item outperformed multiitem scales, an assessment of home smoking rules, and SHS exposure assessed in other residential areas, automobiles and public settings. The sample was less accurate at self-reporting lower levels of SHS exposure (cotinine 0.05-0.215 ng/mL). Conclusions The single item ASHES-7d Home screener is brief, assesses recent SHS exposure over a week's time, and yielded the optimal balance of sensitivity and specificity. The current findings support use of the ASHES- 7d Home screener to detect SHS exposure and can be easily incorporated into assessment of other major vital signs in cardiology. [ABSTRACT FROM AUTHOR]

Objective We propose a novel approach for measuring tobacco use in a community through the chemical analysis of nicotine metabolites in urban wastewater. It offers frequent monitoring and ‘real-time’, ‘evidencebased' estimates of tobacco consumption which may complement epidemiological surveillance systems normally repeated only every few years. Methods Two urinary metabolites of nicotine, namely cotinine and trans-30-hydroxycotinine, were selected as biomarkers of tobacco consumption in urban wastewater. During smoking, a known amount of nicotine is absorbed and after metabolism excreted as metabolites in urine, ending up in the wastewater; quantitative analysis of the metabolites in the wastewater allows back-calculation of the nicotine collectively absorbed by the population producing the sewage and, indirectly, their tobacco use. Representative samples of wastewater were collected from sewage treatment plants in eight Italian cities and analysed by mass spectrometry. Mass loads of the metabolites were used to estimate nicotine consumption. Results Wastewater analysis in the cities under study was used to estimate the number of cigarettes smoked, in order to compare the results of this study with those obtained from population surveys. The number of cigarettes calculated with the two methods were closely comparable and wastewater analysis was sufficiently sensitive to confirm the differences in tobacco consumption between northern and southern Italy, previously described in population surveys. Conclusions The described approach can serve as a supplementary indicator of tobacco consumption in local communities. This approach can provide objective and updated information, which are useful to assess the efficacy of tobacco-control interventions, with the aim of designing and implementing effective tobacco control plans.

Introduction Mentholated cigarettes are at least as dangerous to an individual's health as non-mentholated varieties. The addition of menthol to cigarettes reduces perceived harshness of smoke, which can facilitate initiation. Here, we examine correlates of menthol use, national trends in smoking menthol and non-menthol cigarettes, and brand preferences over time. Methods We estimated menthol cigarette use during 2004-2010 using annual data on persons ≥12 years old from the National Surveys on Drug Use and Health. We adjusted self-reported menthol status for selected brands that were either exclusively menthol or nonmenthol, based on sales data. Data were weighted to provide national estimates. Results Among cigarette smokers, menthol cigarette use was more common among 12-17 year olds (56.7%) and 18-25 year olds (45.0%) than among older persons (range 30.5% to 34.7%). In a multivariable analysis, menthol use was associated with being younger, female and of non-Caucasian race/ethnicity. Among all adolescents, the percentage who smoked non-menthol cigarettes decreased from 2004-2010, while menthol smoking rates remained constant; among all young adults, the percentage who smoked non-menthol cigarettes also declined, while menthol smoking rates increased. The use of Camel menthol and Marlboro menthol increased among adolescent and young adult smokers, particularly non-Hispanic Caucasians, during the study period. Conclusions Young people are heavy consumers of mentholated cigarettes. Progress in reducing youth smoking has likely been attenuated by the sale and marketing of mentholated cigarettes, including emerging varieties of established youth brands. This study should inform the Food and Drug Administration regarding the potential public health impact of a menthol ban. [ABSTRACT FROM AUTHOR]

Objective Scanty and controversial information is available on the impact of macroeconomic fluctuations on smoking behaviour. No study has quantified the effects of fiscal crises on smoking prevalence. This study aimed to investigate the effects of the 2007-2008 economic crisis on smoking prevalence and number of smokers in the USA. Methods Using data from the repeated Behavioural Risk Factor Surveillance System (BRFSS) surveys in pre-crisis (2005-2007) and post-crisis (2009-2010) periods on a total of 1 981 607 US adults, we separated the expected (after allowance for the demographic growth of the US population, secular smoking prevalence trends and changes in sociodemographic characteristics) from the unexpected (assumed attributable to the economic crisis) changes in the number of smokers across different employment statuses. Results Joinpoint regression analysis revealed no significant changes in smoking prevalence trends over the period 2005-2010. The crisis resulted in an increase in the number of smokers in the US by 0.6 million. This is largely due to an unexpected decrease of 1.7 million smokers among employed and an increase of 2.4 million smokers among unemployed individuals, whose smoking prevalence also remains extremely high in the post-crisis period (32.6%). Conclusions The 2008 financial crisis had a weak effect on smoking prevalence. The pro-cyclical relationship (ie, the crisis results in a lower number of smokers) found among the employed is offset by the counter-cyclical relationship (ie, the crisis results in a higher number of smokers) found among unemployed individuals. Public health interventions should specifically target those in unemployment, particularly in hard times. [ABSTRACT FROM AUTHOR]

Introduction There is anecdotal evidence that health messages interpreted from waterpipe tobacco smoking (WTS) research are inconsistent, such as comparing the health effects of one WTS session with that of 100 cigarettes. This study aimed to identify key health themes about WTS discussed by online news media, and how numerical cigarette–waterpipe equivalence (CWE) was being interpreted. Methods We identified 1065 online news articles published between March 2011 and September 2012 using the ‘Google Alerts' service. We screened for health themes, assessed statements mentioning CWE and reported differences between countries. We used logistic regression to identify factors associated with articles incorrectly reporting a CWE equal to or greater than 100 cigarettes, in the absence of any comparative parameter (‘CWE ≥100 cigarettes'). Results Commonly mentioned health themes were the presence of tobacco (67%) and being as bad as cigarettes (49%), and we report on differences between countries. While 10.8% of all news articles contained at least one positive health theme, 22.9% contained a statement about a CWE. Most of these (18.6% total) were incorrectly a CWE ≥100 cigarettes, a quarter of which were made by healthcare professionals/organisations. Compared with the Middle East, articles from the USA and the UK were the most significant predictors to contain a CWE ≥100 cigarettes statement. Conclusions Those wishing to write or publish information related to WTS may wish to avoid comparing WTS to cigarettes using numerical values as this is a major source of confusion. Future research is needed to address the impact of the media on the attitudes, initiation and cessation rates of waterpipe smokers. [ABSTRACT FROM AUTHOR]

Chronic obstructive pulmonary disease (COPD) is a lifestyle-related disease that develops in middle-aged and older adults, often due to smoking habits, and has been noted to cause bone fragility. COPD is a risk factor for osteoporosis and fragility fracture, and a high prevalence of osteoporosis and incidence of vertebral fractures have been shown in patients with COPD. Findings of lung tissue analysis in patients with COPD are primarily emphysema with a loss of alveolar septal walls, and the severity of pulmonary emphysema is negatively correlated with thoracic spine bone mineral density (BMD). On the other hand, epidemiological studies on COPD and fracture risk have reported a BMD-independent increase in fracture risk; however, verification in animal models and human bone biopsy samples has been slow, and the essential pathogenesis has not been elucidated. The detailed pathological/molecular mechanisms of musculoskeletal complications in patients with COPD are unknown, and basic research is needed to elucidate the mechanisms. This paper discusses the impacts of COPD on bone strength, focusing on findings in animal models in terms of bone microstructure, bone metabolic dynamics, and material properties.

Amidst the growing focus on men's health, physical activity (PA) initiatives have demonstrated efficacy in engaging men and providing opportunities to enhance wellbeing outcomes. It is important to capture the characteristics of male populations who attend these initiatives as it yields important implications in terms of reach, design and implementation. This paper presents the pre-adoption characteristics of participants at a site of Football Cooperative (FC), a community-based PA initiative in Ireland. The research sought to ascertain whether the participants involved were an at-risk group in terms of cardiovascular disease (CVD) risk factors (i.e. PA levels, waist circumference, aerobic fitness, diet, smoking, alcohol and sleep quality). Recruitment occurred before and during a return to play period, after a lowering of COVID-19 restrictions in May 2021. Purposeful sampling was used to recruit participants. Fitness and anthropometric data were collected, along with self-report survey data including demographics and wellbeing indicators. A total of n = 71 completed the self-report survey and were predominantly white Irish (95.8%) and married (84.6%). The majority (83.1%) of participants had ≥ 3 CVD risk factors where 66.1% had a waist circumference (WC) of ≥ 94 cm, indicating a high mortality risk. This research suggests that the gendered approach employed by the FC initiative engages a target demographic of at-risk males. While this demonstrates promise in terms of tackling CVD risk, further research that focuses on translating the initiative to engage men at risk of social and economic disadvantage is recommended to enhance the impact of the FC approach.

• First estimation of nitrosamine intake via tobacco by smokers in 30 provinces, China. • First estimation of cancer risk (CR) of nitrosamines in tobacco to smokers in China. • CRs of NNK and NDMA are comparable in tobacco smoke (1.99 × 10−4 vs. 1.66 × 10 -4). • CR by nitrosamine intake: tobacco (3.80 × 10−4) > food (1.74 × 10−4) > water (1.38 × 10−5). • Tobacco smoking brings 202% extra cancer risk of nitrosamines to Chinese smokers. Nitrosamines are a class of carcinogens which have been detected widely in food, water, some pharmaceuticals as well as tobacco. The objectives of this paper include reviewing the basic information on tobacco consumption and nitrosamine contents, and assessing the health risks of tobacco nitrosamines exposure to Chinese smokers. We searched the publications in English from "Web of Science" and those in Chinese from the "China National Knowledge Infrastructure" in 2022 and collected 151 literatures with valid information. The content of main nitrosamines in tobacco, including 4-(methylnitrosoamino)-1-(3-pyridyl)-1-butanone (NNK), N -nitrosonornicotine (NNN), N -nitrosoanatabine (NAT), N -nitrosoanabasine (NAB), total tobacco-specific nitrosamines (TSNA), and N -nitrosodimethylamine (NDMA) were summarized. The information of daily tobacco consumption of smokers in 30 provinces of China was also collected. Then, the intakes of NNN, NNK, NAT, NAB, TSNAs, and NDMA via tobacco smoke were estimated as 1534 ng/day, 591 ng/day, 685 ng/day, 81 ng/day, 2543 ng/day, and 484 ng/day by adult smokers in 30 provinces, respectively. The cancer risk (CR) values for NNN and NNK inhalation intake were further calculated as 1.44 × 10−5 and 1.95 × 10−4. The CR value for NDMA intake via tobacco smoke (inhalation: 1.66 × 10−4) indicates that NDMA is similarly dangerous in tobacco smoke when compared with the TSNAs. In China, the CR values caused by average nitrosamines intake via various exposures and their order can be estimated as the following: smoke (3.75 × 10−4) > food (1.74 × 10−4) > drinking water (1.38 × 10−5). Smokers in China averagely suffer 200% of extra cancer risk caused by nitrosamines in tobacco when compared with non-smokers. [Display omitted] [ABSTRACT FROM AUTHOR]

Background: Electronic nicotine delivery systems (ENDS) offer a substantial harm reduction opportunity for adults who smoke and are unlikely to quit. However, a major concern about ENDS is their use by non-smoking youth, and particularly whether ENDS are acting as a "gateway" that leads youth to later start smoking cigarettes. However, evidence for the gateway hypothesis can be interpreted in alternative ways, e.g. that youth who have certain characteristics were already predisposed to use both ENDS and cigarettes ("common liability" explanation). Aims: This commentary provides an evaluation of the gateway hypothesis that is accessible by a lay audience. This paper first reviews and evaluates the evidence interpreted as supporting the gateway hypothesis. Important alternative explanations (i.e., common liability) are discussed, as are different types of evidence (i.e., population-level trends) that can help differentiate between these competing explanations. Overview: Evidence for the gateway hypothesis is based on the finding that youth who use ENDS are more likely to also smoke cigarettes. However, this evidence suffers from an important flaw: these studies fail to fully account for some youths' pre-existing tendency to use products containing nicotine, and inappropriately interpret the results as ENDS use causing some youth to smoke. Common liability studies suggest that ENDS use does not, in and of itself, directly cause youth to later smoke cigarettes, beyond their pre-existing tendency to use products containing nicotine. Population-level trends show that youth cigarette smoking declined faster after ENDS use became common, which contradicts the central prediction of the gateway hypothesis (i.e. that youth smoking would be more common following ENDS uptake, than otherwise be expected). Conclusion: Evidence offered in support of the gateway hypothesis does not establish that ENDS use causes youth to also smoke cigarettes. Instead, this evidence is better interpreted as resulting from a common liability to use both ENDS and cigarettes. Population-level trends are inconsistent with the gateway hypothesis, and instead are consistent with (but do not prove) ENDS displacing cigarettes. Policies based on misinterpreting a causal gateway effect may be ineffective at best, and risk the negative unintended consequence of increased cigarette smoking. [ABSTRACT FROM AUTHOR]

Background: Nursing interventions in the post‐operative time period including psychological and emotional support, adverse event education, and instructions for follow‐up care contribute patient satisfaction, safety, and quality of life. However, the time spent in the post‐anesthesia care unit (PACU) and hospital continues to shorten around the world to reduce health care spending and improve patient outcomes. Nurses conducting research during the important post‐operative recovery period need to utilize unique techniques and emerging technologies to contact, recruit and collect data outside of the hospital setting including the Research Electronic Data Capture (REDCap) platform. Aims: This paper describes the feasibility and acceptability, facilitators and barriers of the software application, REDCap, to complete a repeated‐measures, descriptive correlational study in patients undergoing outpatient breast cancer surgeries. Methods & Materials: The recruitment, data collection and storage were completed utilizing the secure REDCap Platform. The Institutional Research Board (IRB)‐approved study was a repeated‐measures, descriptive, correlational study with data collection at three time points. The data points aligned with important transitions and routine visits to improve data collection feasibility and increase relevance to clinical practice. Results: The sample consisted of women diagnosed with breast cancer undergoing breast conserving surgery between August 15 and October 15, 2020. There were 123 potential participants, of which 76 started the surveys and 75 participated (61%) responded and participated in the study on Post‐operative Day 1. Fifty‐nine participants (78%) completed the surveys on post‐operative Day 14. Discussion: As the frequency of outpatient treatment increases, nurses conducting post‐operative research will need to collect the data outside of the hospital setting. Conclusion: Email provides a method of studying new phenomena by recruiting participants, providing information about the study, and collecting results in a non‐traditional setting. REDCap provides a method to facilitate nursing research through a securely encrypted integrated process. [ABSTRACT FROM AUTHOR]

Background: Controversy persists regarding the causal relationship between Cigarette smoking, alcohol consumption, and Rosacea. This paper employs the Mendelian randomization (MR) method to elucidate the correlation between Cigarette smoking, alcohol consumption, and Rosacea. The aim is to contribute valuable insights to aid in the prevention and early treatment of Rosacea. Method: Summary datasets for cigarette smoking parameters (Cigarettes smoked per day, Smoking status: Previous, smoking status: Current) and alcohol consumption (Alcoholic drinks per week) were selected alongside data for Rosacea from genome‐wide association studies (GWAS). The Two‐sample MR method was employed to analyze the correlation between cigarette smoking, alcohol consumption, and Rosacea. Various MR analysis methods, including inverse variance weighting (IVW), MR‐Egger, Simple Mode, Weighted Mode, and Weighted Median, were chosen. IVW served as the primary analysis method. Results: The results indicate a significant negative association between Cigarettes smoked per day and Rosacea. Moreover, a significant positive correlation was observed between Smoking status: Previous and Rosacea. However, no significant associations were found between Smoking status: Current, Alcoholic drinks per week, and Rosacea. Conclusion: This study provides further clarity on the association between cigarette smoking, drinking, and Rosacea through a two‐sample MR analysis. Notably, the number of cigarettes smoked per day appears to be associated with a reduced incidence of Rosacea, while cigarette smoking cessation may increase the risk. Surprisingly, alcohol consumption does not emerge as a significant risk factor for Rosacea. These findings contribute to a nuanced understanding of the complex relationship between lifestyle factors and the occurrence of Rosacea, offering potential insights for preventive measures and early intervention.

Background: Substance use is an escalating public health problem in South Africa resulting in risky behaviours and poor educational attainment among adolescents. There is a huge battle to overcome substance use among learners as more drugs become easily available with the mean age of drug experimentation reported to be at 12 years of age. It is important to continuously understand the trends in substance use in order to assess if there are positive changes and provide evidence for the development of context-specific effective interventions. This paper outlines the prevalence of substance use among selected high schools in a district in Limpopo province. Methods: To determine the prevalence of substance use among selected high school learners in a district in Limpopo Province, a cross-sectional school survey of 768 learners was conducted. Data was analysed using SPSS v 26. Descriptive analysis was used to describe the independent and dependent variables and Chi-Square test was used to investigate associations between demographic characteristics and substance use among high school learners. Results: The most abused substances by learners were alcohol (49%), cigarettes (20.8%) and marijuana (dagga/cannabis) (16.8%). In a lifetime, there was a significant difference (P < 0.05) in cigarette smoking with gender, school, and grade; with more use in males (14.2%) than females (7.6%); in urban schools (14.6) than peri-urban (6.7%) and more in Grade 12 (6.4%). There was a significant difference (P < 0.05) in alcohol use with more use in Grade 10 (12.6%) and varied use among male and female learners but cumulatively more alcohol use in females (27.7%). Drug use varied, with an overall high drug use in urban schools (20.7%). Conclusions: Substance use is rife among high school learners in the district and health promotion initiatives need to be tailored within the context of socio-demographic characteristics of learners including the multiple levels of influence such as peer pressure, poverty, unemployment and child headed families. Additional research is required to investigate the factors leading to a notable gradual increase in use among female learners and into the environmental and family settings of learners in influencing substance use.

Background: Childhood, adolescent and young adult (CAYA) cancer survivors are vulnerable to adverse late-effects. For CAYA cancer survivors, tobacco smoking is the most important preventable cause of ill-health and early death. Yet, effective strategies to support smoking cessation in this group are lacking. The PRISM study aims to undertake multi-method formative research to explore the need for, and if appropriate, inform the future development of an evidence-based and theory-informed tobacco smoking cessation intervention for CAYA cancer survivors. Materials and methods: PRISM involves three phases of: 1) an environmental scan using multiple strategies to identify and examine a) smoking cessation interventions for CAYA cancer survivors that are published in the international literature and b) current smoking cessation services in England that may be available to, or tailorable to, CAYA cancer survivors; 2) a qualitative study involving semi-structured interviews with CAYA cancer survivors (aged 16–29 years and who are current or recent ex-smokers and/or current vapers) to explore their views and experiences of smoking, smoking cessation and vaping; and 3) stakeholder workshops with survivors, healthcare professionals and other stakeholders to consider the potential for a smoking cessation intervention for CAYA cancer survivors and what such an intervention would need to target and change. Findings will be disseminated to patient groups, healthcare professionals and researchers, through conference presentations, journal papers, plain English summaries and social media. Discussion: PRISM will explore current delivery of, perceived need for, and barriers and facilitators to, smoking cessation advice and support to CAYA cancer survivors from the perspective of both survivors and healthcare professionals. A key strength of PRISM is the user involvement throughout the study and the additional exploration of survivors' views on vaping, a behaviour which often co-occurs with smoking. PRISM is the first step in the development of a person-centred, evidence- and theory-based smoking cessation intervention for CAYA cancer survivors who smoke, which if effective, will reduce morbidity and mortality in the CAYA cancer survivor population.

Introduction: The goal of this research is to identify the factors that negatively impact the achievement of the minimum clinically significant change (MCID) for the American Shoulder and Elbow Surgeons (ASES) score within the realm of various orthopedic shoulder procedures. Methods: We conducted a comprehensive review of studies published from 2002 to 2023, utilizing OvidMedline and PubMed databases. Our search criteria included terms such as "minimal clinically important difference" or "MCID" along with associated MeSH terms, in addition to "American shoulder and elbow surgeon" or "ASES." We selectively included primary investigations that assessed factors linked to the failure to achieve MCID for the ASES score subsequent to orthopedic shoulder procedures, while excluding papers addressing anatomical, surgical, or injury-related aspects. Results: Our analysis identified 149 full-text articles, leading to the inclusion of 12 studies for detailed analysis. The selected studies investigated outcomes following various orthopedic shoulder procedures, encompassing biceps tenodesis, total shoulder arthroplasty, and rotator cuff repair. Notably, factors, such as gender, body mass index, diabetes, smoking habits, opioid usage, depression, anxiety, workers' compensation, occupational satisfaction, and the preoperative ASES score, were all associated with the inability to attain MCID. Conclusion: In summary, numerous factors exert a negative influence on the attainment of MCID following shoulder procedures, and these factors appear to be irrespective of the specific surgical technique employed. Patients presenting with these factors may perceive their surgical outcomes as less successful when compared to those without these factors. Identifying these factors can enable healthcare providers to provide more effective counseling to patients regarding their expected outcomes and rehabilitation course. Furthermore, these findings can aid in the development of a screening tool to better identify these risk factors and optimize them before surgery. [ABSTRACT FROM AUTHOR]

The authors discuss the report which examines evidence on electronic cigarettes commissioned by the World Health Organization (WHO). They mention that the significant issue to regard is the role of marketing in urging smokers to move away from smoking while not drawing in non-smokers. They say that there is proof that smokers tries electronic (e)-cigarettes due to their desire for safer alternatives and a concern on the health risks of smoking.

OBJECTIVES: Those with any psychiatric diagnosis have substantially greater rates of smoking and are less likely to quit smoking than those with no diagnosis. Using nationally representative data, we sought to provide estimates of smoking and longitudinal cessation rates by specific psychiatric diagnoses and mental health service use. DESIGN AND PARTICIPANTS: Data were analysed from a two-wave cohort survey of a US nationally representative sample (non-institutionalised adults): the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; 2001-2002, n=43 093; 2004-2005, n=34 653). MAIN OUTCOME MEASURES: We examined smoking rates (lifetime, past year and past year heavy) and cross-sectional quit rates among those with any lifetime or past year psychiatric diagnosis (DSM-IV). Importantly, we examined longitudinal quit rates and conducted analyses by gender and age categories. RESULTS: Those with any current psychiatric diagnosis had 3.23 (95% CI 3.11 to 3.35) times greater odds of currently smoking than those with no diagnosis, and were 25% less likely to have quit by follow-up (95% CI 20% to 30%). Prevalence varied by specific diagnoses (32.4% to 66.7%) as did cessation rates (10.3% to 17.9%). Comorbid disorders were associated with higher proportions of heavy smoking. Treatment use was associated with greater prevalence of smoking and lower likelihood of cessation. CONCLUSIONS: Those with psychiatric diagnoses remained much more likely to smoke and less likely to quit, with rates varying by specific diagnosis. Our findings highlight the need to improve our ability to address smoking and psychiatric comorbidity both within and outside of healthcare settings. Such advancements will be vital to reducing mental illness-related disparities in smoking and continuing to decrease tobacco use globally. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To describe relationships between tobacco-related environments and disparities in smoking by sexual orientation. METHODS: We examined three aspects of state-level tobacco environments, which were derived from the ImpacTeen State Level Tobacco Control Policy and Prevalence Database: (1) tobacco price and tax data and tobacco control funding; (2) tobacco control policies and (3) tobacco prevalence and norms data. This information was linked to individual-level data on sexual orientation, tobacco use and nicotine dependence in Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (N=34 653; 577 LGB respondents), a cross-sectional, nationally representative survey of adults in the USA. RESULTS: Lesbian, gay and bisexual (LGB) adults in states with more restrictive tobacco environments were less likely to have ever smoked (AOR=0.78, 95% CI 0.62 to 1.00) and to currently smoke (AOR=0.77, 95% CI 0.60 to 0.99) than LGB adults in more permissive tobacco environments. Further, sexual orientation disparities in past and current smoking, as well as in current nicotine dependence, were lower in states with the most restrictive tobacco environments. Results were robust to adjustment for confounders at the individual and state levels. CONCLUSIONS: Restrictive state-level tobacco environments are correlates of smoking behaviours among LGB adults in the USA; such environments could potentially reduce social inequalities in smoking based on sexual orientation.

Abstract: Background: The 1939 article “Tobacco consumption and lung carcinoma” by Mueller has been praised for its quality and its originality but is still not available in English. Methods: Summary of the 29-page long paper and translation of part of its investigative section. Re-analysis of the clinical and smoking characteristics of the lung cancer cases. Comparison with pre-1945 case–control studies and a similar but prior tobacco and cancer report. Results: The article primarily consists of a detailed description of the smoking, clinical and occupational characteristics of 96, mostly dead, lung cancer cases. Occupation and the flu are discussed for the cases only. The paper makes unexplained assumptions about the smoking habits of 20 cases and is silent about the sampling, recruitment and interview modes of the “healthy” subjects, supposed to reflect “normal tobacco consumption.” The dearth of methodological information distinguishes this paper from case–control studies published before 1939. Major selection and differential misclassification cannot be ruled out. Conclusion: Access to the 1939 Mueller article is provided for non-German speakers. The quality of the group comparison was modest and it did not add qualitatively new knowledge compared to a report published 8years earlier. [Copyright &y& Elsevier]

Cigarette smoke is a complex chemical mixture that causes a variety of diseases, such as lung cancer. With the electrically heated cigarette smoking system (EHCSS), temperatures are applied to the tobacco below those found in conventional cigarettes, resulting in less combustion, reduced yields of some smoke constituents, and decreased activity in some standard toxicological tests. The first generation of electrically heated cigarettes (EHC) also resulted in increased formaldehyde yields; therefore, a second generation of EHC was developed with ammonium magnesium phosphate (AMP) in the cigarette paper in part to address this increase. The toxicological activity of mainstream smoke from these two generations of EHC and of a conventional reference cigarette was investigated in two studies in rats: a standard 90-day inhalation toxicity study and a 35-day inhalation study focusing on lung inflammation. Many of the typical smoke exposure-related changes were found to be less pronounced after exposure to smoke from the second-generation EHC with AMP than to smoke from the first-generation EHC or the conventional reference cigarette, when compared on a particulate matter or nicotine basis. Differences between the EHC without AMP and the conventional reference cigarette were not as prominent. Overall, AMP incorporated in the EHC cigarette paper reduced the inhalation toxicity of the EHCSS more than expected based on the observed reduction in aldehyde yields. [ABSTRACT FROM AUTHOR]

Objectives: The present study examined the feasibility and possible mode effects of using a Web-form versus a paper-form survey to collect alcohol and tobacco data from 3rd and 4th grade students. Methods: A survey regarding alcohol and tobacco use and attitudes was administered to 280 3rd and 4th grade students attending a racially and economically diverse Midwestern urban school district in the spring of 2003. The sample was randomly assigned to complete a Web-form survey (n=137) or a hardcopy paper-form survey (n=143). Results: The overall response rate was 87% and did not differ by survey mode. There were minimal differences between survey modes in data quality including substantive responses to alcohol and tobacco use. Conclusions: The findings of the present study offer preliminary evidence that Web-form surveys can be considered for collecting alcohol and tobacco use data among young children. Although there were few survey mode differences, our findings suggest more research is needed to examine possible measurement errors induced by computer-based approaches of data collection.

Objective The aim of this research was to compare the risk of all-cause mortality and mortality from all cancers combined, lung cancer, respiratory diseases, cardiovascular diseases and diabetes mellitus between normal-weight smokers and overweight or obese ex-smokers. Methods Data were from 1997 to 2004 National Health Interview Survey (with response rates ranging from 70% to 80%) which were linked to records in the National Death Index. Mortality follow-up was through 31 December 2006. The sample was limited to normal-weight smokers and overweight/obese ex-smokers 25 years of age and older (n=52 819). HR from Cox regression was computed to represent mortality effect. Results Results showed that in both women and men, normal-weight smokers, relative to overweight or obese ex-smokers, had a higher risk of mortality from all causes combined, all cancers combined, lung cancer, cardiovascular and respiratory diseases. Among women, there was no difference in mortality risk from diabetes mellitus between normal-weight smokers and overweight or obese ex-smokers. Among men, there was some evidence that the risk of mortality was higher in obese ex-smokers than normal-weight smokers. Conclusions This article concludes that, overall, mortality risk is smaller in overweight or obese ex-smokers than normal-weight smokers. Smoking cessation interventions can tailor messages that highlight the greater reduction in mortality associated with quitting, compared with potential weight gain. [ABSTRACT FROM AUTHOR]
