AI Article Synopsis

  • Waterpipe tobacco (WPT) smoking is rising among U.S. adolescents and young adults, with 4.8% of adolescents and 18.5% of young adults initiating WPT smoking from 2013 to 2018.
  • The study used data from the PATH study and applied survival analysis to identify predictors for both initiation and progression of WPT smoking among different age groups.
  • Key risk factors include lower harm perception, use of other tobacco products, and specific ethnic backgrounds, highlighting that ethnic minority groups have a higher likelihood of starting and continuing WPT smoking.

Article Abstract

Introduction: Waterpipe tobacco (WPT) smoking has increased among the young population in the United States. This study assessed the extent and predictors of WPT smoking initiation and progression among US adolescents (12-17 years) and young adults (18-24 years) longitudinally.

Aims And Methods: We analyzed data from 4 waves (2013-2018) of the Population Assessment of Tobacco and Health (PATH) study comprising 10 692 respondents (adolescents = 5428 and young adults = 5264). Kaplan-Meier survival method estimated probabilities of WPT initiation and progression. Cox proportional hazards regression models delineated predictors of the outcomes.

Results: Between 2013 and 2018, 4.8% of adolescents initiated and 10.6% progressed WPT smoking. Among young adults, 18.5% initiated and 14.1% progressed WPT smoking during the same time interval. Predictors among adolescents included, WPT initiation: Hispanic ethnicity (adjusted odds ratio (aHR) = 1.75, 95% confidence interval (CI) = 1.23-2.49), lower harm perception (aHR = 2.89, 95% CI = 2.10-3.98), and other tobacco products use (aHR = 3.97, 95% CI = 2.73-5.78); WPT progression: illicit drug use (aHR = 4.60, 95% CI = 1.99-10.67). Predictors among young adults included, WPT initiation: non-Hispanic Black (aHR = 2.31, 95% CI = 1.78-3.00), Hispanic (aHR = 1.77, 95% CI = 1.34-2.33), lower harm perception (aHR = 2.77, 95% CI = 2.19-3.50), and other tobacco products use (aHR = 3.14, 95% CI = 2.25-4.38); WPT progression: non-Hispanic Black (aHR = 1.51 95% CI = 1.09-2.10), lower harm perception (aHR = 1.80, 95% CI = 1.41-2.30), and alcohol use (aHR = 1.61, 95% CI = 1.13-2.30).

Conclusions: Results indicate a high prevalence of WPT initiation and progression among adolescents and young adults over time, with minority racial/ethnic groups being at greater risk for both. WPT-specific risk communication interventions (eg, educational campaigns and health warning labels) are warranted to limit WPT smoking among young people.

The purpose of this study was to compare changes in circulating microRNAs -126 (c-miR-126) and -222 (c-miR-222) following acute serial concurrent exercise (SCE) and integrated concurrent exercise (ICE) sessions among young, sedentary adults. Ten males and 9 females completed the study procedures. For SCE, participants performed resistance exercise (RE) followed by aerobic exercise (AE), without mixing the two.

Purpose: To determine the effect of dexmedetomidine on the ED and ED of sufentanil in patient-controlled intravenous analgesia (PCIA) after cesarean section.

Patients And Methods: Parturients who underwent elective cesarean section (n = 80) were randomly assigned to either the sufentanil group (S group) or the dexmedetomidine-sufentanil combination group (DS group). Patients in the S group received a combination of sufentanil, 5 mg of tropisetron, and saline, whereas patients in the DS group were administered 1.

Leber's hereditary optic neuropathy (LHON) is an ocular mitochondrial disease that involves the impairment of mitochondrial complex I, which is an important contributor to blindness among young adults across the globe. However, the disorder has no available cures, since the approved drug idebenone for LHON in Europe relies on bypassing complex I defects rather than fixing them. Herein, mRNA-loaded nanoparticle (mNP)-engineered mitochondria (mNP-Mito) were designed to replace dysfunctional mitochondria with the delivery of exogenous mitochondria, normalizing the function of complex I for treating LHON.
