We recently reported the efficacy of indigo naturalis (IN) in patients with active ulcerative colitis (UC) in a randomized controlled trial (INDIGO study). However, few studies have been conducted to investigate whether IN is effective even in treatment-refractory cases, such as in those with steroid dependency and anti-TNF refractoriness.
MethodsIn the INDIGO study, 86 patients with active UC were randomly assigned to an IN group (0.5–2.0 g daily) or placebo group. The rate of clinical response (CR), mucosal healing (MH), and change in fecal calprotectin (FCP) levels was compared between refractory [patients with steroid-dependent disease, previous use of anti-TNF-α, and concomitant use of immunomodulators (IM)] and non-refractory patients. We also analyzed factors predicting CR and MH at week 8.
ResultsThe rates of CR of IN group were significantly higher than placebo group, even in patients with steroid-dependent disease (p < 0.001), previous use of anti-TNF-α (p = 0.002), and concomitant use of IM (p = 0.013). The rates of MH in IN group were significantly higher than in placebo group in patients with steroid-dependent disease (p = 0.009). In the IN group, median FCP levels, at week 8, were significantly lower than baseline in patients with steroid-dependent disease and patients with the previous use of anti-TNF-α (p < 0.001, respectively). Multivariate analysis indicated that the previous use of anti-TNF-α was not a predictive factor for CR and MH at week 8.
ConclusionsIn a sub-analysis of data from a randomized placebo-controlled trial, we found that IN may be useful even in patients with steroid-dependent disease and patients with the previous use of anti-TNF-α.
相似文献To determine the 1-year and 3-year adherence rates with Positive Airway Pressure (PAP) therapy in patients with schizophrenia compared to matched controls.
MethodsA case–control retrospective analysis was performed in a Veterans Affairs hospital. All symptomatic patients with schizophrenia ever started on PAP therapy between 2007 and 2015 were compared with controls matched for severity of sleep apnea based on AHI, BMI, and age at the time of diagnosis.
ResultsTotal number of subjects in both groups was 39. Mean AHI among cases and controls was 27.63 ± 22.16 and 33.59 ± 44.04 (p = 0.32), mean BMI was 34.91 ± 5.87 and 33.92 ± 5.21 (p = 0.43), and mean age at diagnosis was 53.6 ± 11.75 and 55.97 ± 11.92 (p = 0.36), respectively. There was no statistically significant difference in PAP use between patients with schizophrenia and controls at 1-year (percent days device use > 4 h—36.43% ± 31.41 vs. 49.09% ± 38.76; p = 0.17) and 3-year (percent days device use > 4 h—42.43 ± 35.50 vs. 60.53 ± 38.56; p = 0.089) visits
ConclusionsPAP adherence and usage is not significantly different among patients with schizophrenia compared to matched controls. Therefore, schizophrenia does not appear to influence CPAP compliance.
相似文献Reduced physical activity in many chronic diseases is consistently associated with increased morbidity. Little is known about physical activity in sarcoidosis. The aim of this study was to objectively assess physical activity in patients with pulmonary sarcoidosis and investigate its relationship with lung function, exercise capacity, symptom burden, and health status.
MethodsPhysical activity was assessed over one week in 15 patients with pulmonary sarcoidosis and 14 age-matched healthy controls with a tri-axial accelerometer (ActivPal™) and the International Physical Activity Questionnaire (IPAQ). All participants underwent pulmonary function tests, 6-min walk test (6MWT) and completed the Fatigue Assessment Scale (FAS), Medical Research Council (MRC) Dyspnoea Scale and the King’s Sarcoidosis Questionnaire (KSQ).
ResultsPatients with sarcoidosis had significantly lower daily step counts than healthy controls; mean (SD) 5624 (1875) versus 10,429 (2942) steps (p < 0.01) and a trend towards fewer sit-to-stand transitions each day (p = 0.095). Only two patients (13%) self-reported undertaking vigorous physical activity (IPAQ) compared to half of healthy individuals (p < 0.01). Daily step count was significantly associated with 6MWT distance in sarcoidosis (r = 0.634, p = 0.01), but not with forced vital capacity (r = 0.290), fatigue (r = 0.041), dyspnoea (r = −0.466) or KSQ health status (r = 0.099–0.484). Time spent upright was associated with fatigue (r = −0.630, p = 0.012) and health status (KSQ Lung scores r = 0.524, p = 0.045), and there was a significant correlation between the number of sit-to-stand transitions and MRC dyspnoea score (r = −0.527, p = 0.044).
ConclusionPhysical activity is significantly reduced in sarcoidosis and is associated with reduced functional exercise capacity (6MWD). Fatigue, exertional symptoms and health status were more closely associated with time spent upright and the number of bouts of physical activity, as compared to step counts. Further studies are warranted to identify the factors that determine different physical activity profiles in sarcoidosis.
相似文献Chronic obstructive pulmonary disease (COPD) is a common lung disease characterized by airflow limitation and systemic inflammation. Recently, there has been growing interest in adipose tissue-mediated inflammation in the pathogenesis of COPD. The aim of our study was to determine the relationships between a new adipocytokine, meteorin-like protein (Metrnl), and acute exacerbations of COPD, smoking, and comorbidities.
Materials and MethodsThe study included 313 patients aged 40–65 years in four groups: Group 1: ex-smokers (≥ 20 pack-years) with COPD hospitalized for COPD exacerbation (n = 133), Group 2: current-smokers (≥ 20 pack-years) without COPD (n = 60), Group 3: ex-smokers (≥ 20 pack-years) without COPD (n = 60), and Group 4: never-smokers without COPD (n = 60). Peripheral venous blood samples (5 cc) were collected from all participants. Plasma Metrnl levels were measured using commercial enzyme-linked immunosorbent assay (ELISA) kit.
ResultsMean Metrnl levels were 28.45 ± 11.27 ng/ml in Group 1, 24.34 ± 4.38 ng/ml in Group 2, 18.84 ± 3.8 ng/ml in Group 3, and 19.44 ± 3.92 ng/ml in Group 4. Group 1 had significantly higher mean Metrnl level compared to the other groups (p = 0.006, p = 0.001, p = 0.001). Metrnl level was also significantly higher in Group 2 when compared with Groups 3 and 4 (p = 0.001, p = 0.005). Group 1 patients with diabetes mellitus and coronary artery disease showed significantly lower Metrnl levels compared to other patients in the group (p = 0.001, p = 0.001).
ConclusionThe high Metrnl level in COPD exacerbations and active smoking may be important in balancing the inflammatory response. However, plasma Metrnl levels were found to be lower in COPD patients with comorbidities.
相似文献To evaluate the effects of transcutaneous electrical nerve stimulation (TENS) compared to placebo TENS and a control group on pain, pulmonary function, respiratory muscle strength, and analgesic medications in the postoperative period of thoracotomy in an Intensive care unit (ICU).
MethodsPatients who had undergone posterolateral thoracotomy were randomly allocated to receive TENS during ICU stay, or placebo TENS, or into the control group. All groups received conventional physiotherapy. We analysed the intensity of pain, pulmonary function, respiratory muscle strength, and use of analgesia medications. Outcomes were evaluated before surgery, immediately after, 24 and 48 h after ICU admission.
ResultsForty-five patients were included. Regarding pain perception, there was no difference between groups (p = 0.172), but there was a significant reduction in pain intensity for patients receiving TENS after first physiotherapy session compared to baseline (4.7 ± 3.2 vs 3.3 ± 2.6; p < 0.05). All groups had a decrease in forced vital capacity (FVC) after surgery (p < 0.001). There was no difference between the groups regarding the use of analgesic medications, but a higher intake of morphine and acetaminophen were observed for the control (p = 0.037) and placebo group (p = 0.035), respectively.
ConclusionThe use of TENS provides a little benefit of pain (in the first 12 h) but failed to demonstrate any improvement in the recovery of ICU patients after 48 h of posterolateral thoracotomy.

相似文献To assess the prognostic value of the 8-foot-up-and-go test (8-FUGT) in pilot cohort of patients with idiopathic pulmonary fibrosis (IPF).
MethodsThirty-four patients with IPF (68 ± 8 years) underwent 8-FUGT at baseline and were followed for up to 40 months. Receiver operating characteristics and age-adjusted Cox hazard ratios (HR) were analyzed for 8-FUGT, hospitalizations, and mortality. Correlation coefficients were determined between 8-FUGT and other exercise tests.
Results8-FUGT ≥ 6.9 s was found to be associated with hospitalization (sensitivity = 77%, specificity = 76%, p = 0.03) and mortality (sensitivity = 91%, specificity = 70% p = 0.008) in patients with IPF. Categorical models demonstrated that 8-FUGT ≥ 6.9 s was associated with 14.1- (p < 0.001) and 55.4-fold (p = 0.001) increased risks for hospitalization and mortality, respectively. In continuous models, for every 1-s slower performance in the 8-FUGT there were 54% [HR = 1.54, 95% CI (1.11–2.15) p = 0.01] increased risk for hospitalization and 94% [HR = 1.94, 95% CI (1.26–2.99) p = 0.003] increased risk for mortality. 8-FUGT was inversely related to 6-min walk distance (r = − 0.61), peak oxygen consumption (r = − 0.58), and peak work rate (r = − 0.72), all p < 0.001.
ConclusionsThe 8-FUGT was strongly associated with hospitalizations and mortality in patients with IPF, as well as correlated with established prognostic markers. These novel findings suggest a prognostic value of the 8-FUGT for risk stratification, referral to pulmonary rehabilitation, and considering listing for lung transplantation. 8-FUGT is an inexpensive and practical tool that has prospective for implementation in clinical and research settings in IPF. Future prospective studies should evaluate the effect of changes in 8-FUGT on clinical outcomes.

相似文献Type 2 diabetes mellitus (T2DM) is a polygenic metabolic disorder. SIRT1 has an essential role in the insulin-signaling pathway and energy homeostasis. SIRT1 exerts protective effects in the kidney cells.
ObjectivesWe aimed to investigate whether the rs3758391 variant was associated with diabetic nephropathy, measures of kidney function, and BMI in a population with and without diabetes in southwest Iran.
MethodsThe study comprised 132 patients with type 2 diabetes mellitus (T2DM) (with and without nephropathy). They were compared with 66 normal subjects. The subjects were genotyped for the rs3758391 polymorphism by the PCR–RFLP method. Fasting blood glucose, HbA1c, urea, creatinine, and urinary albumin were measured using a biochemistry analyzer. Serum cystatin C levels were measured by ELISA.
ResultsThe genotype distribution and allele frequencies were significantly different between the entirely diabetic group and the healthy subjects (p value < 0.05). For T2DM, the odds ratios (ORs) for the TT genotype and the T allele carrier were 5.7 (95% confidence interval (CI) 2.2–14.9, p < 0.001) and 4.01 (95% CI 2.1–7.5, p < 0.001), respectively. For diabetic nephropathy, the ORs for the TT genotype and the T allele carrier were 3.96 (95% CI 1.5–10.0, p = 0.003) and 3.0 (95% CI 1.4–6.4, p = 0.003), respectively. For decreased eGFR below 60 mL/min/1.73m2, the OR for TT was 2.9 (95% CI 1.1–7.5, p = 0.02).
ConclusionOur results confirm that the risk allele of the rs3758391 SNP in the SIRT1 gene is strongly associated with T2DM and diabetic nephropathy. The TT genotype is also associated with decreased eGFR.
相似文献Immunocompromised patients with acute diverticulitis are at increased risk of morbidity and mortality. The aim of this study was to compare clinical presentations, types of treatment, and outcomes between immunocompromised and immunocompetent patients with acute diverticulitis.
MethodsWe compared the data of patients with acute diverticulitis extracted from the Web-based International Registry of Emergency Surgery and Trauma (WIRES-T) from January 2018 to December 2021. First, two groups were identified: medical therapy (A) and surgical therapy (B). Each group was divided into three subgroups: nonimmunocompromised (grade 0), mildly to moderately (grade 1), and severely immunocompromised (grade 2).
ResultsData from 482 patients were analyzed—229 patients (47.5%) [M:F = 1:1; median age: 60 (24–95) years] in group A and 253 patients (52.5%) [M:F = 1:1; median age: 71 (26–94) years] in group B. There was a significant difference between the two groups in grade distribution: 69.9% versus 38.3% for grade 0, 26.6% versus 51% for grade 1, and 3.5% versus 10.7% for grade 2 (p < 0.00001). In group A, severe sepsis (p = 0.027) was more common in higher grades of immunodeficiency. Patients with grade 2 needed longer hospitalization (p = 0.005). In group B, a similar condition was found in terms of severe sepsis (p = 0.002), quick Sequential Organ Failure Assessment score > 2 (p = 0.0002), and Mannheim Peritonitis Index (p = 0.010). A Hartmann’s procedure is mainly performed in grades 1–2 (p < 0.0001). Major complications increased significantly after a Hartmann’s procedure (p = 0.047). Mortality was higher in the immunocompromised patients (p = 0.002).
ConclusionsImmunocompromised patients with acute diverticulitis present with a more severe clinical picture. When surgery is required, immunocompromised patients mainly undergo a Hartmann’s procedure. Postoperative morbidity and mortality are, however, higher in immunocompromised patients, who also require a longer hospital stay.
相似文献Systemic immune-inflammation index (SII) has been demonstrated to be closely associated with prognosis of a series of solid tumors. However, its role in small cell lung cancer (SCLC) remains poorly understood. The present study aims to evaluate the prognostic significance of pretreatment SII in SCLC treated with etoposide and platinum-based chemotherapy.
MethodsSixty hundred and fifty-three newly diagnosed SCLC patients were enrolled. The optimal cut-off values for SII and LDH (lactate dehydrogenase) were obtained by a receiver operating characteristic (ROC) curve analysis. Overall survival (OS) was assessed by univariate and multivariate analyses.
ResultsThe optimal cut-off values of pretreatment SII and LDH were 748.51 × 109/L and 188.5 U/L, respectively. High pretreatment SII was significantly associated with advanced tumor stage (limited disease, LD vs. extensive disease, ED; 26.3% vs 46.5%; p < 0.001). On univariate analysis, age < 65 years, female, non-smoker, limited disease, SII < 748.51 × 109/L, LDH < 188.5 U/L, distant metastasis numbers < 2, chemotherapy + radiotherapy, and chemotherapy + surgery were closely correlated with a prolonged OS (p < 0.05). The median OS for patients in high SII group was 12.0 months, compared with that of 17.0 months for patients in low SII group. Multivariate analysis showed smoking history (p = 0.014), tumor stage (p < 0.001), pretreatment SII (p < 0.001), LDH (p = 0.002), distant metastasis numbers (p = 0.006), and chemotherapy + radiotherapy (p < 0.001) were independent prognostic factors of OS. Furthermore, SII remained prognostic significance for SCLC stratified by variable subgroups analysis.
ConclusionPretreatment SII represents a powerful prognostic biomarker for SCLC patients treated with etoposide and platinum-based chemotherapy. It is significant for treatment strategy making in clinics.
相似文献Observational studies in South Asian populations have suggested an association between vitamin B12 status and metabolic traits; however, the findings have been inconclusive. Hence, the aim of the present study was to use a genetic approach to explore the relationship between metabolic traits and vitamin B12 status in a Sri Lankan population and to investigate whether these relationships were modified by dietary intake.
MethodsA total of 109 Sinhalese adults (61 men and 48 women aged 25–50 years) from Colombo City underwent anthropometric and biochemical measurements, dietary intake analysis, and genetic tests. Genetic risk scores (GRS) based on 10 metabolic single nucleotide polymorphisms (SNPs) (metabolic-GRS) and 10 vitamin B12 SNPs (B12-GRS) were constructed.
ResultsThe B12-GRS was significantly associated with serum vitamin B12 (p = 0.008) but not with metabolic traits (p > 0.05), whereas the metabolic-GRS had no effect on metabolic traits (p > 0.05) and vitamin B12 concentrations (p > 0.05). An interaction was observed between B12-GRS and protein energy intake (%) on waist circumference (p = 0.002). Interactions were also seen between the metabolic-GRS and carbohydrate energy intake (%) on waist-to-hip ratio (p = 0.015).
ConclusionOur findings suggest that a genetically lowered vitamin B12 concentration may have an impact on central obesity in the presence of a dietary influence; however, our study failed to provide evidence for an impact of metabolic-GRS on lowering B12 concentrations. Given that our study has a small sample size, further large studies are required to confirm our findings.
相似文献Robot-assisted ventral mesh rectopexy is considered a valid option in the treatment of rectal prolapse. However, it involves higher costs than the laparoscopic approach. The aim of this study is to determine if less expensive robotic surgery for rectal prolapse can be safely performed.
MethodsThis study was conducted on consecutive patients who underwent robot-assisted ventral mesh rectopexy at Fondazione Policlinico Universitario “A. Gemelli” IRCCS, Rome, from 7 November 2020 to 22 November 2021. The cost of hospitalization, surgical procedure, robotic materials, and operating room resources in patients undergoing robot-assisted ventral mesh rectopexy with the da Vinci Xi Surgical Systems was analyzed before and after technical modifications, including the reduction of robotic arms and instruments, and the execution of a double minimal peritoneal incision at the pouch of Douglas and sacral promontory (instead of the traditional inverted J incision).
ResultsTwenty-two robot-assisted ventral mesh rectopexies were performed [21 females, 95.5%, median age 62.0 (54.8–70.0) years]. After an initial experience performing traditional robot-assisted ventral mesh rectopexy in four patients, we adopted technical modifications in other cases. No major complication or conversion to open surgery occurred. In total, mean cost of hospitalization, surgical procedure, robotic materials, and operating room resources was €6995.5 ± 1058.0, €5912.7 ± 877.0, €2797.6 ± 545.6, and €2608.3 ± 351.5, respectively. Technical modifications allowed a significant reduction in the overall cost of hospitalization (€6604.5 ± 589.5 versus €8755.0 ± 906.4, p = 0.001), number of robotic instruments (3.1 ± 0.2 versus 4.0 ± 0.8 units, p = 0.026), and operating room time (201 ± 26 versus 253 ± 16 min, p = 0.003).
ConclusionsConsidering our preliminary results, robot-assisted ventral mesh rectopexy with appropriate technical modifications can be cost-effective and safe.
相似文献Chronic cough management is challenging as this condition is often associated with multiple comorbidities, requiring a multidisciplinary diagnostic approach. Little is known about the characteristics of obese patients with chronic cough. This study aims to describe treatable traits of chronic cough and the response to pump proton inhibitor (PPI) therapy in this sub-group of patients.
MethodsA retrospective, observational study was performed in patients with chronic cough in a French University Hospital. Characteristics of chronic cough were analyzed for obese (N = 112) and non-obese (N = 355) patients. Refractory cough was estimated at 6 and 12 months.
ResultsThe 3 main treatable traits associated with chronic cough in obese patients and non-obese patients were gastroesophageal reflux disease (GERD), asthma, and upper airway cough syndrome (UACS). A noticeable difference was the higher frequency of GERD (47.3% vs 34.6%, p = 0.0188) and obstructive sleep apnea (OSA) (9.8% vs 3.1%, p = 0.0080) in obese patients compared to non-obese patients. Pump proton inhibitor (PPI) treatment had a significantly higher success rate in obese patients (32.5% vs 17.0%, p < 0.05) and refractory cough at 12 months was less frequently reported in obese patients (22.3% vs 34.1%, p < 0.05).
ConclusionIn a context of chronic cough, a higher prevalence of GERD was noted in obese patients compared to non-obese patients and obese patients were more responsive to PPI treatment. Moreover, OSA was reported more frequently as a treatable trait in obese patients and should be considered early in the diagnostic evaluation. Prospective clinical studies that evaluate the contribution of obesity to chronic cough are further needed.
相似文献The present work was conducted to estimate the prevalence of adult Behçet’s disease (BD) in adult Egyptian and to study the clinical pattern and influence of age at-onset and sex on disease phenotype. Also, we investigated the spectrum of presentation and frequencies along the north-to-south gradient of the country.
Patients and methodThe population-based, multicenter, cross-sectional study included 1526 adult BD patients from 26 specialized Egyptian rheumatology centers. Demographic, clinical, and therapeutic data are assessed for all patients.
ResultsThe mean age of patients was 35.7 ± 9.84 years, disease duration 6.58 ± 5.25 years, and age at onset 29.37 ± 8.6 years; 91 were juvenile-onset (JoBD). There were 1102 males and 424 females (M:F 2.6:1). Regarding co-morbidities, 19.92% were diabetic, and 26.05% were hypertensive. The mean body mass index was 27.57 ± 5.24 (43.1% overweight; 25.9% obese). The mean BD current activity form was 4.48 ± 4.28. Regarding the medications use, systemic steroid and colchicine were the most common drugs used (947 (90.2%) and 611 (82.7%), respectively). The overall estimated prevalence of BD in Egypt was 3.6/100,000 population being highest in the two main cities: Alexandria (15.27) and Cairo (8.72). Pathergy test was positive in 43.4%. 90.2% were receiving systemic steroids and 8.3%, biologics. Disease characteristics were comparable between JoBD and adult-onset BD cases. Central nervous system (CNS), deep venous thrombosis (DVT), and gastrointestinal (GIT) involvement were significantly higher in males (p = 0.01, p = 0.001, and p = 0.001 respectively) while joint affection (p = 0.001) and disease activity (p = 0.011) were increased in females.
ConclusionsThis study provides current prevalence of BD in Egypt; 3.6/100,000 with no remarkable north-to-south gradient. The sex influences the disease phenotype with the CNS, DVT, and GIT involvement are higher in males, while the joint affection and disease activity were increased in females.
Key Points• The prevalence and phenotype of Behçet’s disease across Egypt is presented in a multicenter nationwide study.
• The potential influence of the age at onset and sex on disease phenotype is highlightened.
• A review of the literature worldwide is presented allowing comparisons with studies from other nations.
相似文献Pain is the most debilitating symptom of recurrent acute pancreatitis (RAP) and chronic pancreatitis (CP) and often requires chronic opioids or total pancreatectomy with islet autotransplantation to manage. Pain is a complex experience that can be exacerbated by depression and vice versa. Our aim was to test the hypothesis that depression-associated genes are associated with a constant-severe pain experience in RAP/CP patients.
StudyA retrospective study was done using North American Pancreatitis Study II (NAPS2) genotyped RAP and CP patients with completed case report forms (n = 1,357). Subjects were divided based on pattern of pain and pain severity as constant-severe pain (n = 787) versus not constant-severe pain (n = 570) to conduct a nested genome-wide association study. The association between reported antidepressant medication use and depression gene loci was tested.
ResultsConstant-severe pain was reported in 58% (n = 787) of pancreatitis patients. No differences in sex or alcohol consumption were found based on pain severity. Antidepressant use was reported in 28% (n = 223), and they had lower SF-12 mental quality of life (MCS, p < 2.2 × 10− 16). Fifteen loci associated with constant-severe pain (p < 0.00001) were found to be in or near depression-associated genes including ROBO2, CTNND2, SGCZ, CNTN5 and BAIAP2. Three of these genes respond to antidepressant use (SGCZ, ROBO2, and CTNND2).
ConclusionDepression is a major co-factor in the pain experience. This genetic predisposition to depression may have utility in counseling patients and in instituting early antidepressant therapy for pain management of pancreatitis patients. Prospective randomized trials are warranted.

相似文献In contrast to tobacco smoking, electronic cigarette (“vaping”) advertisement had been approved in the United Kingdom (UK) in January 2013. Currently, there are an estimated 3.2 million UK e-cigarette users. The impact of e-cigarette advertisement on tobacco use has not been studied in detail. We hypothesised that e-cigarette advertisement impacts on conventional smoking behaviour.
MethodsA cross-sectional structured survey assessed the impact of e-cigarette advertising on the perceived social acceptability of cigarette and e-cigarette smoking and on using either cigarettes or e-cigarettes (on a scale of 1 to 5/‘not at all’ to ‘a lot’). The survey was administered between January to March 2015 to London university students, before and after viewing 5 UK adverts including a TV commercial.
ResultsData were collected from 106 participants (22 ± 2 years, 66% male), comprising cigarette smokers (32%), non-smokers (54%) and ex-smokers (14%). This included vapers (16%), non-vapers (77%) and ex-vapers (7%). After viewing the adverts, smokers (2.6 ± 1.0 vs. 3.8 ± 1.1, p = 0.001) and non-smokers (3.2 ± 0.7 vs. 3.7 ± 0.8, p = 0.007) felt smoking was more socially acceptable, compared to before viewing them. Participants were more likely to try both e-cigarettes (1.90 ± 1.03 to 3.09 ± 1.11, p < 0.001) and conventional cigarettes (1.73 ± 0.83 to 2.27 ± 1.13, p < 0.001) after viewing the adverts compared to before. Vapers were less likely to smoke both an e-cigarette, and a conventional cigarette after viewing the adverts.
ConclusionE-cigarette advertising encourages both e-cigarette and conventional cigarette use in young smokers and non-smokers. The adverts increase the social acceptability of smoking without regarding the importance of public health campaigns that champion smoking cessation.
