Respiratory health and quality of life in young exclusive, habitual smokers - a comparison of waterpipe smokers, cigarette smokers and non-smokers

Clinical phenotype of obstructive sleep apnea in older adults: a hospital-based retrospective study in China

BACKGROUND

The prevalence of obstructive sleep apnea (OSA) in older people (aged over 65 years) is high. However, OSA in older populations has not received sufficient attention. This study examined the clinical phenotypic characteristics of older patients with newly diagnosed OSA.

METHODS

A total of 110 older patients (≥ 65 years) and 220 younger patients (< 65 years), matched by gender, body mass index (BMI), and apnea-hypopnea index (AHI), were enrolled in this retrospective study. Clinical manifestations, comorbidities, and polysomnographic results were compared between the two groups, and correlations between age ≥ 65 years and OSA comorbidities were explored.

RESULTS

Nocturia was more common in older patients with OSA, as with lower sleep efficiency, longer wake after sleep onset, increased stage N1 sleep, and decreased stage N3 sleep and average SpO2. The proportions of older OSA patients who had comorbid hypertension, coronary artery disease (CAD), chronic obstructive pulmonary disease, and ischemic stroke were significantly higher than those of younger patients. The incidence of tonsillar enlargement and pharyngeal narrowing was lower in older patients. Age ≥ 65 years was an independent risk factor for patients with OSA to have hypertension (OR: 1.89, 95% CI: 1.11-3.21), CAD (OR: 4.83, 95% CI: 2.29-10.21), and ischemic stroke (OR: 2.92, 95% CI: 1.02 to 8.38).

CONCLUSIONS

The presence of OSA in older adults was associated with significant abnormalities of sleep architecture, aggravated nocturnal hypoxia and increased risks of hypertension, CAD, and stroke, which can be distinguished as a unique clinical phenotype.

Factors Predicting Dependence on Waterpipe Smoking Among Waterpipe Exclusive Smokers

ABSTRACT

The current study targeted a sample of waterpipe (WP) exclusive smokers to identify the levels and predictors of dependence on this smoking pattern and to examine the relationship between WP smoking (WPS) dependence and depressive symptoms. A cross-sectional research design was employed with a community sample of 270 subjects who are currently WP exclusive smokers. Assessment of WPS dependence and depressive symptoms was performed using self-report measures. About 62.6% of the subjects were WPS dependent. The unique significant predictors of WPS dependence were age, depression levels, age of starting WPS, duration of WPS, income, smoking WP daily, the belief of being attracted to WPS, and the desire to stop WPS. These predictors explained 35% of the variance in WPS dependence. WPS dependence was associated with increased depressive symptoms. Although few studies have been conducted, the WPS dependence prevalence appears to be alarmingly high among WP exclusive smokers. Factors associated with WPS dependence provide useful information that can be used to tailor WP prevention interventions.

The adverse health effects of waterpipe smoking in adolescents and young adults: A narrative review

Waterpipe (WP) smoking has rapidly grown in popularity in the United States and other Western countries with the fastest uptake among younger individuals. This growth has been encouraged by the misperception that WP smoke is harmless or less harmful than cigarette smoke. To better understand how WP affects the health of young people, we conducted a narrative review of the literature focusing on the adverse health effects of WP smoking in adolescents and younger adults. We searched scientific literature databases including PubMed, MEDLINE, EMBASE, and ISI Web and selected papers that met the inclusion criteria. Sixty-three papers met the inclusion criteria and were selected for review. Data were abstracted from the selected papers into a standardized table. The evidence demonstrates that WP smoking can cause acute lung infection and injury, and carbon monoxide (CO) poisoning, in adolescents and young adults. It is also associated with adverse subclinical effects in this sub-population, including oral and systemic genotoxicity, lung function decline, and the alteration of vascular and hemodynamic functions. Limited evidence that is available indicates associations with psychological and neurological effects and asthma. No identified publications examined the association between WP use and type 2 diabetes, a condition that is associated with cigarette smoking among young people. WP smoking by younger individuals can result in their hospitalization due to systemic CO poisoning and acute lung disease, and induce subclinical adverse effects in the oral cavity, pulmonary system, and in circulation, that are involved in the pathogenesis of local and systemic chronic diseases.

The impacts of waterpipe (hookah, narghile) -use on quality of life: a special report

Introduction While waterpipe-use induced deficiency and incapacity have already been extensively explored, its impacts on quality of life (QoL) was rarely raised. The main aim of this Special Report was to briefly highlight the key results of the studies raising the effects of waterpipe-use on smokers' QoL. Areas covered SCOPUS was consulted on July 3^rd, 2020, using the combination of the following two medical subject headings (MeSH) words: 'Tobacco, Waterpipe' AND 'Quality of Life'. Only English original articles were retained. Merely five studies raised the effects of waterpipe-use on QoL. Studies were performed in Middle East (n = 2), USA (n = 1), Tunisia (n = 1) and 'Egypt, Morocco, Oman and Jordan' (n = 1). Conflicting results were reported related to the effects of waterpipe-use on QoL. While four studies concluded that waterpipe-smokers' have a worse QoL, one study concluded that waterpipe-smokers have a normal QoL. Expert opinion This Special Report is a call to encourage future research to identify the real effects of waterpipe-use on QoL.

Smoking and sleep apnea duration mediated the sex difference in daytime sleepiness in OSA patients

PURPOSE

Daytime sleepiness is a common symptom of obstructive sleep apnea (OSA) and is more common in men, but the underlying mechanism remains unclear. The aim of this study was to assess whether or not sex differences in daytime sleepiness persisted after controlling for age and OSA severity and to explore the factors contributing to daytime sleepiness in patients with OSA.

METHODS

A total of 104 pairs of patients with OSA, matched by age and apnea-hypopnea index (AHI), were enrolled in this retrospective study. Demographic data were collected; daytime sleepiness was measured by the Epworth Sleepiness Scale (ESS); and polysomnography (PSG) was performed on each participant. These measurements were compared between sexes, and the factors affecting daytime sleepiness were explored with correlation and multivariate linear regression analyses.

RESULTS

Men had significantly higher ESS scores (p = 0.021) than women. Regarding demographics, BMI, neck/height ratio, and proportion of habitual smoking and alcohol intake were significantly higher in men. Regarding PSG findings, men had more rapid eye movement sleep, a longer mean apnea-hypopnea duration, and a longer mean apnea duration (MAD). Regression analysis showed that two sex-associated variables, habitual smoking (β = 0.189, p = 0.006) and MAD (β = 0.154, p = 0.024), had the strongest association with ESS scores. Further analysis revealed that MAD was significantly influenced by apnea index (β = 0.306, p < 0.001) and sex (β = - 0.193, p = 0.003).

CONCLUSION

The sex difference in daytime sleepiness persists in patients with OSA, even after matching AHI and age. The difference is mediated by sex-specific smoking habits and sex differences in apnea duration.

Self-rated peri-implant oral symptoms and clinicoradiographic characteristics in Narghile-smokers, cigarette-smokers, and nonsmokers with peri-implantitis

BACKGROUND

The hypothesis is that self-rated peri-implant oral symptoms (OS) and clinical (plaque index [PI] and probing depth [PD]) and radiographic (crestal bone loss [CBL]) are higher in (cigarette-smokers [CS]) and (waterpipe-users) than (nonsmokers [NS]). The aim was to relate peri-implant self-perceived OS with clinico-radiographic parameters among CS, waterpipe-users, and NS.

MATERIALS AND METHODS

This study was performed on self-reported CS, waterpipe-users, and NS with peri-implantitis. A questionnaire was used to record peri-implant self-perceived OS (pain in gums, bleeding gums, bad breath, and loose implant) and demographic data (age, sex, duration of smoking and waterpipe usage, duration of implants in function, duration since diagnosis of peri-implantitis). Clinico-radiographic parameters (CBL, PD, PI, and bleeding on probing [BOP]) were also measured; and compared with the self-perceived OS. Group comparisons were done for perceived OS and clinico-radiographic variables, and significant differences were deemed when P-values were under .05.

RESULTS

One hundred male participants (35 CS, 33 waterpipe-users, and 32 NS) with peri-implantitis were included. Pain in gums (P < .05) and bad breath (P < .05) were more frequently perceived by CS and waterpipe-users than NS. There was no significant difference in perceived bleeding gums around the implant or loose implant among all groups. The CBL (P < .01), PI (P < .001), and PD (P < .01) were significantly high in CS and waterpipe-users than NS. NS (P < .05) had significantly higher BOP than waterpipe-users and CS. There was no significant difference in CBL, PI, PD, and BOP among waterpipe-users and CS.

CONCLUSION

Tobacco-smokers present with worse peri-implant perceived OS and clinicoradiograhic parameters than nonsmokers with peri-implantitis.
