Factors associated with intentions to quit tobacco use in Lebanon: A cross-sectional survey.

Introduction: The prevalence of tobacco smoking in Lebanon is among the highest globally. This study aims to determine past attempts to quit smoking among adults and identify factors associated with intentions to quit. Methods: A nationally representative telephone survey was conducted between June and August 2022. Eligibility criteria included people aged >=18 years residing in Lebanon. The questionnaire was divided into three components: socio-demographic characteristics, cigarette and waterpipe tobacco use behaviours. Binary logistic regression was used to examine factors associated with intention to quit cigarette and waterpipe tobacco use. Results: A total of 2003 respondents were included in the study. The prevalence of any tobacco product use was 41%, the prevalence of current cigarette smoking was 41% and the prevalence of current waterpipe tobacco use was 20%. Approximately 24% of adults who smoke cigarettes and 26% of those who use waterpipe tobacco had previous quit attempts mainly due to health concerns. Intentions to quit smoking within the next 6 months were reported among 12% of survey respondents. Among adults who smoke, past quit attempts increased the likelihood of intentions to quit cigarette smoking by 5-fold (OR: 5.11; 95% CI: 1.80-14.47, p = 0.002) and waterpipe tobacco use by 7-fold (OR: 6.98, 95% CI: 2.63-18.51, p = <0.001). Age and income were associated with intentions to quit cigarette but not waterpipe tobacco use. Conclusion: Intention to quit smoking was strongly associated with past quitting attempts. Understanding factors associated with intentions to quit can help inform the development of context specific smoking cessation interventions.

Factors Associated With Oral Anticoagulant Use in Patients With Atrial Fibrillation and Mental Disorders.

Objective: This study aims to identify how mental illness severity interacts with oral anticoagulant (OAC) patterns among people with atrial fibrillation (AF).Methods: AF patients with comorbid mental illness (classified using ICD-10) were identified from the South London and Maudsley Biomedical Research Centre Case Register. CHA2DS2-VASc and ORBIT scales were used to calculate stroke and bleeding risks, respectively, whereas Health of the Nation Outcome Scales (HoNOS) assessment was used for functional impairment.Results: Overall, 2,105 AF patients were identified between 2011 and 2019. Serious mental illness (SMI) was associated with lower prescription of any OAC (adjusted risk ratio [aRR]: 0.94; 95% CI, 0.90-0.99). A total of 62% of SMI patients at risk of stroke were not prescribed an OAC. In the AF cohort, alcohol or substance dependence and activities of daily living (ADL) impairment were associated with lower prescription of warfarin (aRR: 0.92; 95% CI, 0.86-0.98 and aRR: 0.96; 95% CI, 0.93-0.99, respectively). Among people with AF and SMI, warfarin was less likely to be prescribed to people with self-injury (aRR: 0.84; 95% CI, 0.77-0.91), hallucinations or delusions (aRR: 0.92; 95% CI, 0.85-0.99), ADL impairment (aRR: 0.91; 95% CI, 0.84-0.99), or alcohol or substance dependence (aRR: 0.92; 95% CI, 0.87-0.98). Among people with AF and comorbid substance use disorder, self-injury (aRR: 0.78; 95% CI, 0.64-0.96), cognitive problems (aRR: 0.84; 95% CI, 0.70-0.99), and other mental illnesses (aRR: 0.83; 95% CI, 0.70-0.99) were associated with lower prescription of warfarin.Conclusions: An OAC treatment gap for AF patients with comorbid SMI relative to other mental illnesses was identified. The gap was wider in those with dependence comorbidities, positive symptoms, self-injury, or functional impairment.J Clin Psychiatry 2024;85(1):23m14824.

From knowledge production to knowledge translation: Waterpipe tobacco control research in the Eastern Mediterranean Region.

Waterpipe tobacco smoking (WTS) rates in the Eastern Mediterranean Region (EMR) are the highest worldwide, particularly among young people. Although fiscal policies to curb tobacco use have been recommended by the World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC), implementation has been suboptimal. The Eastern Mediterranean Consortium on the Economics of Waterpipe Tobacco Smoking (ECON-WTS) was formed in response to this need to produce knowledge on the economics of WTS in the EMR and apply a comprehensive Knowledge translation (KT) framework. The KT framework comprised priority setting, evidence synthesis, knowledge translation, and knowledge uptake. In this article, we discuss the approaches followed in applying the KT framework to WTS control, providing examples and noting challenges and lessons learned where possible.

Anticoagulation therapy and outcomes in patients with atrial fibrillation and serious mental illness: A systematic review and meta-analysis.

OBJECTIVE: A systematic review was conducted to investigate prevalence, management and outcomes of atrial fibrillation (AF) in people with Serious Mental Illnesses (SMI) versus the general population. DATA SOURCES: MEDLINE, EMBASE, and PsycINFO were searched for primary research written in English and published between 2004 and 2022. STUDY SELECTION: A total of 1459 studies were identified in the initial search of which 16 met the inclusion criteria. Studies (n = 4) reporting on ischaemic stroke and major bleeding events were included in the meta-analysis. DATA EXTRACTION: Two independent reviewers extracted data and assessed risk of bias using the Newcastle-Ottawa Scale. Discrepancies were resolved by consulting a third reviewer. RESULTS: Low rates of AF were reported among people with SMI suggesting under-recognition or recording gaps. People with SMI and AF were less likely to receive oral anticoagulation therapy compared to the general population. When receiving warfarin, those with bipolar disorder experienced poor anticoagulation control as measured by time in INR therapeutic range. Pooled analysis of risk estimates showed that in patients with identified AF, SMI was not significantly associated with an increased risk of stroke (HR: 1.09; 95%CI: 0.85 to 1.40; I2 = 60%, p = 0.04) or major bleeding (HR: 1.11; 95%CI: 0.95 to 1.28; I2 = 57%, p = 0.03) when adjusted for underlying stroke and bleeding risks using the CHA2DS2VASc and HASBLED scales respectively. CONCLUSION: More research is needed to examine the prevalence, management and outcomes of AF in this population, and to evaluate the effect of the introduction of the novel anti-coagulants on these metrics over time.

Anticoagulation for atrial fibrillation in people with serious mental illness in the general hospital setting.

OBJECTIVE: People with serious mental illnesses (SMI) have an increased risk of stroke compared to the general population. This study aims to evaluate oral anticoagulation prescription trends in atrial fibrillation (AF) patients with and without a comorbid SMI. METHODS: An open-source retrieval system for clinical data (CogStack) was used to identify a cohort of AF patients with SMI who ever had an inpatient admission to King's College Hospital from 2011 to 2020. A Natural Language Processing pipeline was used to calculate CHA2DS2-VASc and HASBLED risk scores from Electronic Health Records free text. Antithrombotic prescriptions of warfarin and Direct acting oral anti-coagulants (DOACs) (apixaban, rivaroxaban, dabigatran, edoxaban) were extracted from discharge summaries. RESULTS: Among patients included in the study (n = 16 916), 2.7% had a recorded co-morbid SMI diagnosis. Compared to non-SMI patients, those with SMI had significantly higher CHA2DS2-VASc (mean (SD): 5.3 (1.96) vs 4.7 (2.08), p < 0.001) and HASBLED scores (mean (SD): 3.2 (1.27) vs 2.5 (1.29), p < 0.001). Among AF patients having a CHA2DS2-VASc ≥2, those with co-morbid SMI were less likely than non-SMI patients to be prescribed an OAC (44% vs 54%, p < 0.001). However, there was no evidence of a significant difference between the two groups since 2019. CONCLUSION: Over recent years, DOAC prescription rates have increased among AF patients with SMI in acute hospitals. More research is needed to confirm whether the introduction of DOACs has reduced OAC treatment gaps in people with serious mental illness and to assess whether the use of DOACs has improved health outcomes in this population.

Effect of a Home-Based, Walking Exercise Behavior Change Intervention vs Usual Care on Walking in Adults With Peripheral Artery Disease: The MOSAIC Randomized Clinical Trial.

Importance: Home-based walking exercise interventions are recommended for people with peripheral artery disease (PAD), but evidence of their efficacy has been mixed. Objective: To investigate the effect of a home-based, walking exercise behavior change intervention delivered by physical therapists in adults with PAD and intermittent claudication compared with usual care. Design, Setting, and Participants: Multicenter randomized clinical trial including 190 adults with PAD and intermittent claudication in 6 hospitals in the United Kingdom between January 2018 and March 2020; final follow-up was September 8, 2020. Interventions: Participants were randomized to receive a walking exercise behavior change intervention delivered by physical therapists trained to use a motivational approach (n = 95) or usual care (n = 95). Main Outcomes and Measures: The primary outcome was 6-minute walking distance at 3-month follow-up (minimal clinically important difference, 8-20 m). There were 8 secondary outcomes, 3 of which were the Walking Estimated Limitation Calculated by History (WELCH) questionnaire (score range, 0 [best performance] to 100), the Brief Illness Perceptions Questionnaire (score range, 0 to 80 [80 indicates negative perception of illness]), and the Theory of Planned Behavior Questionnaire (score range, 3 to 21 [21 indicates best attitude, subjective norms, perceived behavioral control, or intentions]); a minimal clinically important difference was not defined for these instruments. Results: Among 190 randomized participants (mean age 68 years, 30% women, 79% White race, mean baseline 6-minute walking distance, 361.0 m), 148 (78%) completed 3-month follow-up. The 6-minute walking distance changed from 352.9 m at baseline to 380.6 m at 3 months in the intervention group and from 369.8 m to 372.1 m in the usual care group (adjusted mean between-group difference, 16.7 m [95% CI, 4.2 m to 29.2 m]; P = .009). Of the 8 secondary outcomes, 5 were not statistically significant. At 6-month follow-up, baseline WELCH scores changed from 18.0 to 27.8 in the intervention group and from 20.7 to 20.7 in the usual care group (adjusted mean between-group difference, 7.4 [95% CI, 2.5 to 12.3]; P = .003), scores on the Brief Illness Perceptions Questionnaire changed from 45.7 to 38.9 in the intervention group and from 44.0 to 45.8 in the usual care group (adjusted mean between-group difference, -6.6 [95% CI, -9.9 to -3.4]; P < .001), and scores on the attitude component of the Theory of Planned Behavior Questionnaire changed from 14.7 to 15.4 in the intervention group and from 14.6 to 13.9 in the usual care group (adjusted mean between-group difference, 1.4 [95% CI, 0.3 to 2.5]; P = .02). Thirteen serious adverse events occurred in the intervention group, compared with 3 in the usual care group. All were determined to be unrelated or unlikely to be related to the study. Conclusions and Relevance: Among adults with PAD and intermittent claudication, a home-based, walking exercise behavior change intervention, compared with usual care, resulted in improved walking distance at 3 months. Further research is needed to determine the durability of these findings. Trial Registrations: ISRCTN Identifier: 14501418; ClinicalTrials.gov Identifier: NCT03238222.

Influence of a University Tobacco-Free Policy on the Attitudes, Perceptions of Compliance, and Policy Benefit Among the University Students: A Pre-Post Investigation.

Objective: To evaluate the effectiveness of a university tobacco-free policy by examining differences in students' attitudes, perceptions of compliance and policy benefits, after one year of the policy's implementation. Methods: Cross-sectional studies were undertaken to collect data pre- and 1 year post-policy implementation. The two samples were selected using stratified random sampling. Results: The prevalence of smoking decreased from 26% pre-policy implementation to 21% 1 year after (p = 0.035). The proportion of smokers who thought the policy had contributed to a reduction in smoking frequency increased from 10% to 70% (p < 0.001). Smokers' support for the policy rose from 42 to 58% (p = 0.007). Conclusion: Against the background of a strongly pro-tobacco environment in Lebanon, it is possible to create a positive change in the mindset of smokers at the levels of the education and smoking cessation and more efforts should be expended to bring it about.

Association of health warning labels and motivation to quit waterpipe tobacco smoking among university students in the Eastern Mediterranean Region.

INTRODUCTION: This study aimed to determine associations between health warning label content and motivation to quit waterpipe smoking by gender and smoking location. METHODS: Convenience samples of university students in three Eastern Mediterranean countries - Egypt (n=442), Jordan (n=535) and Palestine (n=487) - completed an online survey assessing health warning labels. Multinomial logit regression models were conducted to determine the association between different variables, particularly gender and smoking location, with motivation to quit. RESULTS: In Palestine, female smokers were more motivated to quit waterpipe smoking when seeing textual warning labels related to children (T2) and pregnancy (T6) [T2: 1.8 (95% CI: 1.1-2.8), T6: 2.7 (95% CI: 1.6-4.3)] compared to males. Similar results were found in Jordan [T2: 1.6 (95% CI: 1.0-2.6), T6: 1.8 (95% CI: 1.1-3.0)]. As for the smoking location, home-only smokers in Palestine were more likely to quit in response to the following warnings: waterpipe smoking is addictive T1: 2.3 (95% CI: 1.4-3.7), harmful for children T2: 2.3 (95% CI: 1.4-4.1), harmful for the baby during pregnancy T6: 2.4 (95% CI: 1.3-4.3), and to believe that quitting reduces the health risks T9: 1.8 (95% CI: 1.0-3.1). These results were not found in Jordan nor Egypt. Smokers reported that the most noticeable location of a HWL on a waterpipe device is the mouthpiece. CONCLUSIONS: A better understanding of motivation to quit and its association with various warnings and smoking location could guide countries on which warnings to require in legislation and where best to require them particularly in relation to location.

Evaluating a tobacco-free university policy: A repeated cross-sectional survey of faculty and staff in Lebanon.

INTRODUCTION: A growing body of research has evaluated the effect of university tobacco-free policies on faculty and staff, however, none of these studies has been carried out in the Eastern Mediterranean Region. This study evaluates changes in faculty and staff attitudes, perceptions and smoking behavior, at 1 year post adoption of a tobacco-free policy in a medium-sized university in Lebanon and the region. METHODS: Two cross-sectional surveys were conducted in 2017 and 2018: baseline and at 1 year post policy implementation. A random sample of 625 and 624 participants took part in the 2017 and 2018 studies, respectively. RESULTS: Faculty and staff had a positive attitude towards the policy at the two time points. The belief that there should be exceptions to the policy significantly decreased from 79% to 59% (p=0.002) among all smokers, particularly those with lower educational attainment (81% to 57%, p=0.007). Perception of compliance among peer smokers increased from 73% to 87% (p=0.009). The proportion of smokers did not significantly change at 1 year post policy implementation, however, 44% of smokers with lower educational attainment, compared to only 7% of those with higher educational attainment (p<0.001), reported a decrease in their smoking behavior outside campus. CONCLUSIONS: The policy had a positive effect on the attitude, behavior and perception of policy benefits among smokers with lower educational attainment, who constitute the majority of smokers. Findings from this study inform and support future efforts to develop university and workplace tobacco-free policies.

Microbial transformation of oxandrolone with Macrophomina phaseolina and Cunninghamella blakesleeana.

Microbial transformation of oxandrolone (1) was carried out by using Cunninghamella blakesleeana and Macrophomina phaseolina. Biotransformation of 1 with M. phaseolina yielded four new metabolites, 11ß,17ß-dihydroxy-17α-(hydroxymethyl)-2-oxa-5α-androstan-3-one (2), 5α,11ß,17ß-trihydroxy-17α-methyl-2-oxa-androstan-3-one (3), 17ß-hydroxy-17α-methyl-2-oxa-5α-androstan-3,11-dione (4), and 11ß,17ß-dihydroxy-17α-methyl-2-oxa-5α-androstan-3-one (5). Whereas a new metabolite, 12ß,17ß-dihydroxy-17α-methyl-2-oxa-5α-androstan-3-one (6), was obtained through the microbial transformation of oxandrolone (1) with C. blakesleeana. The structures of isolated metabolites were characterized on the basis of MS and NMR spectroscopic data.

Microbial transformation of anti-cancer steroid exemestane and cytotoxicity of its metabolites against cancer cell lines.

BACKGROUND: Microbial transformation of steroids has been extensively used for the synthesis of steroidal drugs, that often yield novel analogues, not easy to obtain by chemical synthesis. We report here fungal transformation of a synthetic steroidal drug, exemestane, used for the treatment of breast cancer and function through inhibition of aromatase enzyme. RESULTS: Microbial transformation of anti-cancer steroid, exemestane (1), was investigated by using two filamentous fungi. Incubation of 1 with fungi Macrophomina phaseolina, and Fusarium lini afforded three new, 11α-hydroxy-6-methylene-androsta-1, 4-diene-3,17-dione (2), 16ß, 17ß-dihydroxy-6-methylene-androsta-1, 4-diene-3-one (3), and 17ß-hydroxy-6-methylene-androsta-1, 4-diene-3, 16-dione (4), and one known metabolites, 17ß-hydroxy-6-methylene-androsta-1, 4-diene-3-one (5). Their structures were deduced spectroscopically. Compared to 1 (steroidal aromatase inactivator), the transformed metabolites were also evaluated for cytotoxic activity by using a cell viability assay against cancer cell lines (HeLa and PC3). Metabolite 2 was found to be moderately active against both the cell lines. CONCLUSIONS: Biotransformation of exemestane (1) provides an efficient method for the synthesis of new analogues of 1. The metabolites were obtained as a result of reduction of double bond and hydroxylation. The transformed product 2 exhibited a moderate activity against cancer cell lines (HeLa and PC3). These transformed products can be studied for their potential as drug candidates.
