Behavioural support and nicotine replacement therapy for smokeless tobacco cessation in Bangladesh, India and Pakistan: A pilot randomized controlled trial.

Smokeless tobacco (ST) use in South Asia is high, yet interventions to support its cessation are lacking. We tested the feasibility of delivering interventions for ST cessation in South Asia. We used a 2× 2 factorial design, pilot randomized controlled trial with a duration of 26 weeks, including baseline and follow-up (6, 12 and 26 weeks) assessments. Two primary health-care facilities each in Dhaka (Bangladesh) and Karachi (Pakistan) and a walk-in cancer screening clinic in Noida (India) took part. Adult daily ST users willing to make a quit attempt within 30 days. Of 392 screened, 264 participants [mean age: 35 years, standard deviation = 12.5, 140 (53%) male] were recruited between December 2020 and December 2021; 132 from Bangladesh, 44 from India and 88 from Pakistan. Participants were randomized to one of three treatment options [8-week support through nicotine replacement therapy (NRT, n= 66), a behavioural intervention for smokeless tobacco cessation in adults (BISCA, n= 66) or their combination (n= 66)] or the control condition of very brief advice (VBA) to quit (n= 66). Recruitment and retention, data completeness and feasibility of intervention delivery were evaluated. Biochemically verified abstinence from tobacco, using salivary cotinine, was measured at 26 weeks. Retention rates were 94.7% at 6 weeks, dropping to 89.4% at 26 weeks. Attendance in BISCA pre-quit (100%) and quit sessions (86.3%) was high, but lower in post-quit sessions (65.9%), with variability among countries. Adherence to NRT also varied (45.5% Bangladesh, 90% India). Data completion for key variables exceeded 93% among time-points, except at 26 weeks for questions on nicotine dependence (90%), urges (89%) and saliva samples (62.7%). Among follow-up time-points, self-reported abstinence was generally higher among participants receiving BISCA and/or NRT. At 26 weeks, biochemically verified abstinence was observed among 16 (12.1%) participants receiving BISCA and 13 (9.8%) participants receiving NRT. This multi-country pilot randomized controlled trial of tobacco cessation among adult smokeless tobacco users in South Asia demonstrated the ability to recruit and retain participants and report abstinence, suggesting that a future definitive smokeless tobacco cessation trial is viable.

Adapting a Financial Incentives Intervention for Smoking Cessation With Alaska Native Families: Phase 1 Qualitative Research to Inform the Aniqsaaq (To Breathe) Study.

Alaska Native and American Indian (ANAI) peoples in Alaska currently experience a disproportionate burden of morbidity and mortality from tobacco cigarette use. Financial incentives for smoking cessation are evidence-based, but a family-level incentive structure has not been evaluated. We used a community-based participatory research and qualitative approach to culturally adapt a smoking cessation intervention with ANAI families. We conducted individual, semistructured telephone interviews with 12 ANAI adults who smoke, 12 adult family members, and 13 Alaska Tribal Health System stakeholders statewide between November 2022 and March 2023. Through content analysis, we explored intervention receptivity, incentive preferences, culturally aligned recruitment and intervention messaging, and future implementation needs. Participants were receptive to the intervention. Involving a family member was viewed as novel and aligned with ANAI cultural values of commitment to community and familial interdependence. Major themes included choosing a family member who is supportive and understanding, keeping materials positive and encouraging, and offering cash and noncash incentives for family members to choose (eg, fuel, groceries, activities). Participants indicated that messaging should emphasize family collaboration and that cessation resources and support tips should be provided. Stakeholders also reinforced that program materials should encourage the use of other existing evidence-based cessation therapies (eg, nicotine replacement, counseling). Adaptations, grounded in ANAI cultural strengths, were made to the intervention and recruitment materials based on participant feedback. Next steps include a beta-test for feasibility and a randomized controlled trial for efficacy. This is the first study to design and adapt a financial incentives intervention promoting smoking cessation among ANAI peoples and the first to involve the family system. Feedback from this formative work was used to develop a meaningful family-level incentive structure with ANAI people who smoke and family members and ensure intervention messaging is supportive and culturally aligned. The results provide qualitative knowledge that can inform future family-based interventions with ANAI communities, including our planned randomized controlled trial of the intervention.

Body weight change during a smoking cessation intervention for individuals with overweight or obesity

IntroductionA more comprehensive understanding of the factors regarding weight control in individuals with overweight or obesity after quitting smoking is needed. The study aimed to analyze the changes of in-treatment variables during a smoking cessation intervention and examine their impact on weight. MethodsA total of 120 individuals who smoke with overweight or obesity (MBMI = 31.75 ± 4.31; 54.16 % female) participated in a cognitive-behavioral therapy for smoking cessation and weight control or the same treatment plus contingency management. Weight, smoking variables (cotinine and continuous abstinence), eating behaviors (appetite, grazing), exercise, and sleep were assessed weekly throughout the treatment. ResultsMore participants gained weight over time with reduced nicotine use or abstinence. There was a tendency during treatment to increase appetite and exercise time, while grazing episodes and sleeping hours remained stable. Higher baseline weight (p < .001), greater cotinine reduction (p = .021) and time (p = .009) were associated with greater weight gain, while more hours of exercise (p = .003), no appetite changes (p = .003) and diminished appetite (p < .001) were associated with less gain over the treatment. Both treatment conditions showed similar results in all in-treatment variables. DiscussionIndividuals with overweight and obesity with higher baseline weight and higher baseline cotinine levels during smoking cessation interventions may require special attention to improve weight outcomes. Exercise and appetite regulation may be useful for mitigating weight gain in smoking cessation interventions for individuals with overweight or obesity.

Retrospective evaluation of COVID-19 incidence during smoking cessation treatment with varenicline

Background: Cholinergic anti-inflammatory pathway endogenously controls inflammatory processes through activation of the α7-nicotinic acetylcholine receptor (α7nAChR). Varenicline, used in smoking cessation therapy, is a full α7nAChR agonist with anti-inflammatory effects. In this study, the frequency of coronavirus disease (COVID-19) was evaluated in patients using varenicline as a smoking cessation treatment.&#x0D; Methods: In this retrospective cross-sectional study, records of the 111 patients admitted to Smoking Cessation Outpatient Clinic of Dokuz Eylul University Faculty of Medicine during the COVID-19 pandemic were evaluated. The development of COVID-19 disease according to the status of the patients being positive for SARS-COV-2 was evaluated comparatively in patients who received varenicline or not. Additionally, the disease symptoms were questioned. &#x0D; Results: SARS-CoV-2 PCR positivity was not detected in any of 38 patients who regularly used varenicline out of 68 patients evaluated. SARS-CoV-2 PCR positivity was detected in 13 (43.3%) of 30 patients who received other treatments or irregularly used varenicline (p

Adolescent nicotine exposure induces long-term, sex-specific disturbances in mood and anxiety-related behavioral, neuronal and molecular phenotypes in the mesocorticolimbic system.

The majority of lifetime smokers begin using nicotine during adolescence, a critical period of brain development wherein neural circuits critical for mood, affect and cognition are vulnerable to drug-related insults. Specifically, brain regions such as the medial prefrontal cortex (mPFC), the ventral tegmental area (VTA), nucleus accumbens (NAc) and hippocampus, are implicated in both nicotine dependence and pathological phenotypes linked to mood and anxiety disorders. Clinical studies report that females experience higher rates of mood/anxiety disorders and are more resistant to smoking cessation therapies, suggesting potential sex-specific responses to nicotine exposure and later-life neuropsychiatric risk. However, the potential neural and molecular mechanisms underlying such sex differences are not clear. In the present study, we compared the impacts of adolescent nicotine exposure in male vs. female rat cohorts. We performed a combination of behavioral, electrophysiological and targeted protein expression analyses along with matrix assisted laser deionization imaging (MALDI) immediately post-adolescent exposure and later in early adulthood. We report that adolescent nicotine exposure induced long-lasting anxiety/depressive-like behaviors, disrupted neuronal activity patterns in the mPFC-VTA network and molecular alterations in various neural regions linked to affect, anxiety and cognition. Remarkably, these phenotypes were only observed in males and/or were expressed in the opposite direction in females. These findings identify a series of novel, sex-selective biomarkers for adolescent nicotine-induced neuropsychiatric risk, persisting into adulthood.

The feasibility and efficacy of the group-based therapy for smoking cessation in Klang Valley, Malaysia.

Tobacco epidemic is a global public health concern, killing more than 8 million people annually. Individual therapy is the standard of care of behavioral intervention for smoking cessation in Malaysia and group-based therapy for smoking cessation is an alternative to behavioral intervention commonly used in the western population effectively. The study explored the feasibility and efficacy of group-based therapy for smoking cessation for smokers who want to quit smoking at a quit smoking clinic and community centers in an urban setting in Malaysia. A total of 40 participants who were active smokers and fulfilled the criteria were recruited for the study at the quit smoking clinic. Participants were given behavioral support based on the GBT-M module and individually for 7 weeks with both groups receiving behavioral intervention plus pharmacotherapy. The median age of participants was 48 years for individual therapy and 45 years for group therapy. Group-based therapy was comparable to individual therapy in smoking abstinence outcome at 4 weeks post quit date (35% vs 30%). Group-based therapy was equally effective compared to individual therapy, similar to the western population. Using a group format should allow more people to be treated by a therapist, and therefore could be more cost-effective. Group-based therapy is an option to be included as part of the smoking cessation program in Malaysia.

Modification of Experimental Model of Necrotizing Enterocolitis (NEC) in Rat Pups by Single Exposure to Hypothermia and Hypoxia and Impact of Mother's Milk on Incidence of Disease.

BACKGROUND Necrotizing enterocolitis (NEC) is a potentially life-threatening disease that affects the intestine of the neonate, causing necrosis and general inflammation. Treatment consists of feeding cessation and antibiotic therapy. In more severe cases, surgical intervention is necessary. Recently, different NEC models have been used to study the development of novel diagnostic and therapeutic methods. This work modified an experimental NEC model in rat pups by a single exposure of animals to NEC-causing factors and testing the impact of mother's milk on prevalence of the disease. MATERIAL AND METHODS Fifty rat pups were subjected to the NEC protocol, in which they were exposed to 100% nitrogen atmosphere and cold stress for set periods of time and formula feeding with exposure to mother's milk and artificial milk. Twenty-nine pups were used for control. After a set time of 72 h, bowel fragments were obtained and examined histologically by hematoxylin-eosin staining with a modified 3-grade scale. RESULTS Histological features of NEC were present in most of the samples (10/14) in the group exposed to 1 min of hypoxia (P=0.016), 10 min of cold stress (P=0.4) and formula feeding every 3 h with no mother's milk (P=0.001). In the group of 11 animals with the same stress conditions but fed mother's milk right after birth, only 1 sample of NEC was present. CONCLUSIONS The modified experimental NEC model based on formula feeding and single exposure to hypothermia and hypoxia was assessed statistically and histologically. In this model, mother's milk had a protective effect against necrotizing enterocolitis.

Prenatal passive smoking at home: The experiences of women in Thailand.

Passive smoking poses a threat to the well-being of an unborn baby; however, women's understanding and practice in this regard remain unclear. This study aimed to describe prenatal passive smoking at home based on the experiences of women in Thailand. A qualitative descriptive approach was employed. Data were collected between September 2020 and April 2022 through semi-structured in-depth interviews with 16 postpartum women purposively selected from five hospitals. Thematic analysis was used for data analysis. Three themes emerged. The first theme, 'safeguard for an unborn baby,' was performed through smoking reduction, far distance, abstinence from smoke/odor inhalation, and residual elimination since harm was highly aware. However, justifying safety from the absence of smoke and foul odor was misperceived. The second theme, 'intervention for smoking cessation,' was attempted through various methods, including acquired empathy, persuasion, compromise, and supportiveness. They also needed family/friend assistance in warning and professional care in terms of advice, health education, learning materials, cessation therapy, care continuation, and dealing with complex situations. The last theme, 'maternal perseverance,' was acquired by the motives of safety goals, rights/responsibilities, changeable norms, and a golden period. Pregnant women persistently aimed to prevent their husbands from smoking and safeguard their unborn babies from passive smoking. However, misunderstandings and improper practices were observed. Healthcare and nursing services need comprehensive approaches to enhance understanding, perseverance, and tailored practices catering to women's needs.

Video consultation and treatment in the community smoking cessation therapy success rates in patients with mental illness: a randomized controlled trial

Purpose Smoking is the single factor with the highest impact on reducing life expectancy of patients with mental illness. Patients experience difficulty in participating in smoking cessation programs but are concerned about the impact of tobacco on their health and finances. Smoking cessation advice via videoconferencing might be an alternative to an ordinary in-person consultation. Material and Method Randomized controlled trial with follow-up at 6 months. We included patients with diagnoses of schizophrenia and affective disorder from psychiatric outpatient clinics. Intervention 1 involved daily video consultations; intervention 2 was treatment as usual. Results Seventy patients were included. For both/all groups/interventions, rates of smoking cessation were 45% and predictors for a 50% reduction in smoking were antipsychotic medication load [odds ratio (OR) 0.54; p = 0.045] and number of nicotine patches (OR 1.02; p = 0.06). Predictors for a reduction in the number of cigarettes to < 10 were antipsychotic medication load (OR 0.52; p = 0.04), number of nicotine patches (OR 1.01; p = 0.02) and number of cigarettes at baseline [OR 0.95 (p = 0.09); adjusted OR 0.94 (p = 0.02)]. Patients prevented weight gain during the cessation period. Conclusion The smoking cessation rate was high. One of the reasons for the high cessation rate was that the intervention was carried out by highly experienced and professionally qualified staff. In addition, we used free nicotine patches to increase the patients’ motivation to quit smoking. It is very important that we introduce these results into our clinical work with the patients.

Individual variations in motives for nicotine self-administration in male rats: evidence in support for a precision psychopharmacology

The significant heterogeneity in smoking behavior among smokers, coupled with the inconsistent efficacy of approved smoking cessation therapies, supports the presence of individual variations in the mechanisms underlying smoking. This emphasizes the need to shift from standardized to personalized smoking cessation therapies. However, informed precision medicine demands precision fundamental research. Tobacco smoking is influenced and sustained by diverse psychopharmacological interactions between nicotine and environmental stimuli. In the classical experimental rodent model for studying tobacco dependence, namely intravenous self-administration of nicotine, seeking behavior is reinforced by the combined delivery of nicotine and a discrete cue (nicotine+cue). Whether self-administration behavior is driven by the same psychopharmacological mechanisms across individual rats remains unknown and unexplored. To address this, we employed behavioral pharmacology and unbiased cluster analysis to investigate individual differences in the mechanisms supporting classical intravenous nicotine self-administration (0.04 mg/kg/infusion) in male outbred Sprague–Dawley rats. Our analysis identified two clusters: one subset of rats sought nicotine primarily for its reinforcing effects, while the second subset sought nicotine to enhance the reinforcing effects of the discrete cue. Varenicline (1 mg/kg i.p.) reduced seeking behavior in the former group, whereas it tended to increase in the latter group. Crucially, despite this fundamental qualitative difference revealed by behavioral manipulation, the two clusters exhibited quantitatively identical nicotine+cue self-administration behavior. The traditional application of rodent models to study the reinforcing and addictive effects of nicotine may mask individual variability in the underlying motivational mechanisms. Accounting for this variability could significantly enhance the predictive validity of translational research.

Dynamic effects of ventral hippocampal NRG3/ERBB4 signaling on nicotine withdrawal-induced responses

Tobacco smoking remains a leading cause of preventable death in the United States, with approximately a 5% success rate for smokers attempting to quit. High relapse rates have been linked to several genetic factors, indicating that the mechanistic relationship between genes and drugs of abuse is a valuable avenue for the development of novel smoking cessation therapies. For example, various single nucleotide polymorphisms (SNPs) in the gene for neuregulin 3 (NRG3) and its cognate receptor, the receptor tyrosine-protein kinase erbB-4 (ERBB4), have been linked to nicotine addiction. Our lab has previously shown that ERBB4 plays a role in anxiety-like behavior during nicotine withdrawal (WD); however, the neuronal mechanisms and circuit-specific effects of NRG3-ERBB4 signaling during nicotine and WD are unknown. The present study utilizes genetic, biochemical, and functional approaches to examine the anxiety-related behavioral and functional role of NRG3-ERBB4 signaling, specifically in the ventral hippocampus (VH) of male and female mice. We report that 24hWD from nicotine is associated with altered synaptic expression of VH NRG3 and ERBB4, and genetic disruption of VH ErbB4 leads to an elimination of anxiety-like behaviors induced during 24hWD. Moreover, we observed attenuation of GABAergic transmission as well as alterations in Ca2+-dependent network activity in the ventral CA1 area of VH ErbB4 knock-down mice during 24hWD. Our findings further highlight contributions of the NRG3-ERBB4 signaling pathway to anxiety-related behaviors seen during nicotine WD.

Effectiveness of the QuitSure Smartphone App for Smoking Cessation: Findings of a Prospective Single Arm Trial.

Digital therapies, especially smartphone apps for active and continuous smoking cessation support, are strongly emerging as an alternative smoking cessation therapy. In the Indian context, there is a growing interest in the use of app-based smoking cessation programs; however, there is limited evidence regarding their effectiveness in achieving long-term continuous abstinence. This study aimed to evaluate the long-term abstinence effect (up to 30-d abstinence postprogram completion) of a smartphone app, QuitSure, for smoking cessation in active smokers from India. In this prospective single-arm study, participants who signed up for the QuitSure app were enrolled in this study. The primary end point was the prolonged abstinence (PA) rate from weeks 1 to 4 (day 7 to day 30). Furthermore, data for withdrawal symptoms, relapse reasons, and reasons for not continuing the program were also assessed. The quit rate was calculated considering only the participants who followed up and completed the survey sent to them (per protocol) at day 7 and at day 30, respectively. The PA rate at day 7 was found to be 64.5% (111/172; 95% CI 56% to 72%), and the PA rate at day 30 was found to be 55.8% (72/129; 95% CI 45% to 65%). Within the 7-day abstinence period, 60.4% (67/111) of the participants did not have any withdrawal symptoms. The most common mild withdrawal symptoms were mild sleep disturbance (21/111, 18.9%), mild digestive changes (19/111, 17.1%), and coughing (17/111, 15.3%). Severe withdrawal symptoms were rare, with only 5.4% (6/111) experiencing them. For those achieving 30-day postprogram abstinence, 85% (61/72) had no mild withdrawal symptoms, and 99% (71/72) had no severe withdrawal symptoms. Among successful quitters at day 7, a total of 72.1% (80/111) reported minimal to no cravings, which increased to 88% (63/72) at day 30. Furthermore, 78% (56/72) of those with PA at day 30 reported no change in weight or reduced weight. Among participants experiencing relapse, 48% (28/58) cited intense cravings, 28% (16/58) mentioned facing a tragedy, and 26% (15/58) reported relapsing due to alcohol consumption. The PA rates as a result of the QuitSure program were found to be better than those reported in the results of other smoking-cessation app programs' studies. The QuitSure app yields high PA rates and ameliorates symptoms associated with smoking cessation. In order to obtain conclusive evidence regarding the effectiveness and efficacy of the QuitSure program, future research should include appropriate control measures. Nevertheless, the QuitSure program can serve as a valuable adjunct to a conventional smoking cessation treatment program to aid sustained abstinence.

Impact of Smoking Cessation Therapy on Pulmonary Function: Identification of Factors Predicting Improvement of Forced Expiratory Volume in 1s

Background: Stopping smoking has beneficial effects on pulmonary function, but few studies have investigated which factors predict a favorable outcome. Methods: We analyzed the results of a prospective 3-month smoking cessation program. Smokers who had quit were defined as those abstaining from smoking between visits at 8 and 12 weeks (verified by exhaled carbon monoxide ≤10 ppm). Baseline pulmonary function was compared with that at the end of the program.

Detectable ctDNA at the time of treatment cessation of ipilimumab and nivolumab for toxicity predicts disease progression in advanced melanoma patients.

Immune checkpoint inhibition (ICI) has led to unprecedented outcomes for melanoma patients but is associated with toxicity. ICI resumption after high grade irAEs poses a significant challenge in the clinical management of melanoma patients and there are no biomarkers that can help identify patients that might benefit from resuming treatment. This study aims to determine if circulating tumor DNA (ctDNA) levels at the time of treatment-limiting irAE could guide treatment decisions in this clinical context. This is a retrospective exploratory biomarker study from 34 patients treated with combination ICI for stage IV melanoma. Patients had a treatment-limiting toxicity and a baseline plasma collection prior to commencing ICI and within 6 weeks of stopping therapy. Blood samples were tested for ctDNA at baseline and cessation therapy. Median progression free survival (PFS) and overall survival (OS) have not been reached (24-month PFS rate 54% and OS rate 72.3%). PD occurred in 47% (16/34) of patients. Median PFS with detectable ctDNA from plasma collected at the time of toxicity was 6.5 months while not reached (NR) with undetectable levels (HR: 4.0, 95% CI 0.95-17.5, p=0.0023). Median OS with detectable ctDNA at cessation for toxicity was 19.4 months and NR for undetectable ctDNA (HR: 3.9, 95%CI 20.8-18.6, p=0.024). Positive ctDNA at the time of cessation was highly specific (specificity 0.94, 95% CI 0.74-0.99, PPV 0.88, 95% CI 0.53-0.99). However, ctDNA negativity has low sensitivity as a predictor of ongoing disease control (sensitivity 0.437, 95% CI 0.23-0.67). Notably, 4/9 (44%) ctDNA negative patients who had disease progression had brain only disease progression. Undetectable ctDNA and CR on imaging after stopping immunotherapy for toxicity results in high rates of long-term durable control. For patients with immunotherapy related toxicity, who have persistent ctDNA at 8 - 12 weeks, the risk of disease progression is significant.

Ponesimod-Associated Macular Edema: Onset and Resolution

Purpose: To present a patient with cystoid macular edema (CME) associated with ponesimod use and offer suggestions for the management of this condition. Methods: A case report is presented. Results: A 75-year-old woman with relapsing-remitting multiple sclerosis had an unremarkable baseline ophthalmic examination prior to starting ponesimod. At her 9-month follow-up, an examination showed the development of CME in the left eye. The patient’s macular edema fully resolved after transitioning off ponesimod to an alternative systemic medication and starting treatment with a topical corticosteroid and nonsteroidal anti-inflammatory drug. Conclusions: To our knowledge, this is the first case report discussing the entity and management of ponesimod-associated macular edema. Ponesimod cessation and concomitant topical therapy can result in successful resolution of macular edema.

Multimodal Prehabilitation for Peripheral Arterial Disease Patients with Intermittent Claudication—A Pilot Randomized Controlled Trial

To establish the feasibility and safety of multimodal prehabilitation (MP), and to obtain pilot data on the change in quality of life, functional walking capacity, and the need for surgery for a full-scale trial. Pilot randomized controlled trial that included patients older than 50years old suffering from moderate to severe intermittent claudication and who were candidates for endovascular revascularization (ER). Participants were excluded if they presented with ischemic rest pain, gangrene or ulceration of the index leg, significant lesions in the iliac vessels, planned surgical bypass, comorbidities in which exercise was contraindicated or if they were unable to speak English or French. Participants were randomized in a 1:1 ratio to 12weeks of MP or institutional standard of care (unsupervised walking advice). MP consisted of i)1 weekly supervised exercise session; ii) home-based exercise prescription; iii) nutritional counseling and supplementation; iv) smoking cessation therapy; and v) psychosocial support. Feasibility and safety were measured with recruitment and retention rates, as well as the occurrence of any adverse events. In addition, barriers to attend supervised sessions and compliance to each component were assessed. Change in functional walking capacity, health-related quality of life, and the rates of patients deciding not to undergo ER were collected and analyzed throughout the follow-up period of 12months. Of the 37 patients referred for eligibility, 27 (73%) accepted to participate in the trial and were randomized. Of the 27 patients included, 24 completed the 12-week program. Adherence to each prehabilitation component was 83% interquartile range [72,93] for supervised exercise, 90% [83,96] for home-based exercise and 69% [45,93] for nutritional sessions. Fifty percent of patients were referred for and underwent psychosocial intervention and 40% of the active smokers enrolled in the smoking cessation program. No adverse events were observed during the program. The 2 main barriers for not fully adhering to the intervention were excessive pain while performing the exercises and the difficulty to keep up with the prescribed exercises. A statistically significant mean change (standard deviation (SD)) was seen in the MP group versus standard of care for functional capacity, mean (SD) 6 Min Walk Test 60 (74) vs. -11 (40) meters P<0.05, and quality of life mean (SD) VascuQol 1.15 (0.54) vs. -0.3 (1.09) points P<0.05. There was no statistically significant difference between groups in the rates of patients deciding to undergo ER during the 1-year follow-up period. The results of this pilot trial demonstrate that MP is safe and feasible. A 12-week MP program seems to improve quality of life and functional walking capacity to a greater extent than unsupervised walking advice. There is a need for a large-scale trial to investigate the effectiveness of MP at improving quality of life and assessing its impact on the rates of patients deciding not to undergo or delay ER. The long-term functional and quality of life outcomes of the patients deciding to undergo ER after prehabilitation also need to be assessed.

Smoking Cessation: A Review

Smoking is a leading cause of preventable death worldwide. Smoking damages almost all organs and body systems and reduces the overall health of a person with the highest mortality, especially due to respiratory and cardiovascular disease. Evidence shows that the symptoms and prognosis of smoking-related diseases will improve after smoking cessation. Smoking cessation is one of the most important ways to improve the prognosis of patients with respiratory ailments. Counseling and treatment can increase the chances of smokers to successfully smoke cessation. Smoking cessation therapy must include pharmacological treatment (Nicotine Replacement Therapy (NRT), bupropion, varenicline or N-acetylcysteine) combined with nonpharmacological therapy.
