The contemporary use of emergency pericardiocentesis in trauma: A nationwide trend analysis
Pericardiocentesis is a critical skill taught by the Advanced Trauma Life Support (ATLS®) course, yet substantial knowledge gaps exist regarding recent practice changes and indications for pericardiocentesis. This study aims to characterize contemporary practice patterns and nationwide trends in the use of emergency pericardiocentesis in trauma. A retrospective study of the National Trauma Data Bank (2011−2022) identified patients undergoing pericardiocentesis within 48 h of arrival prior to any cardiac repair surgery. The primary outcomes were pericardiocentesis timing and the proportion of patients with significant cardiac injuries (Abbreviated Injury Scale 3, 5, or 6). Patient characteristics and clinical course were analyzed. Trend analysis was conducted using the Cochran–Armitage test. A total of 1036 patients were included; 59 % sustained blunt trauma, and 25 % were hypotensive on arrival. Median time to pericardiocentesis was 38 min [IQR: 19–74] for penetrating trauma and 78 min [IQR: 24–314] for blunt trauma. Following pericardiocentesis, 79 % of penetrating and 34 % of blunt trauma patients were taken to the operating room. From 2011 to 2022, there was a significant downward linear trend in the proportion of patients diagnosed with cardiac injuries in penetrating trauma (range: 55 % to 27 %; P for trend < 0.001), while blunt trauma cases showed no significant change (range: 15 % to 9 %; P for trend = 0.623). Emergent pericardiocentesis is used differently in penetrating and blunt trauma. The likelihood of identifying cardiac injuries has declined over time in penetrating trauma. In contrast, blunt trauma patients were more likely to undergo delayed pericardiocentesis, with fewer proceeding to surgery. These observed differences in timing and surgical progression may reflect evolving clinical practices and decision-making patterns in trauma care. This changing trend provides insight into evolving trauma care and highlights the contemporary role of pericardiocentesis in trauma. •Significant downward trend in cardiac injury diagnoses after pericardiocentesis in penetrating trauma.•Persistent diagnostic challenges in identifying blunt cardiac injury.•Distinct clinical decision thresholds between blunt and penetrating trauma cases.•Opportunities to refine trauma protocols and ATLS® training in accordance with contemporary clinical practice.
Potential Public Health Effects of Reducing Nicotine Levels in Cigarettes in the United States
Using a simulation model, the FDA has estimated that lowering the nicotine content in cigarettes to a minimally addictive level could substantially reduce tobacco-related mortality.
Estimating the Potential Public Health Impact of Prohibiting Characterizing Flavors in Cigars throughout the US
Flavored cigar use is common among cigar smokers, particularly those at younger ages. Several US localities have implemented policies restricting the sale of flavored tobacco products, including cigars. We estimated the population health benefits of removal of flavored cigars throughout the US in terms of reductions in cigar smoking-attributable mortality due to increased cessation and reductions in cigar smoking prevalence due to decreased initiation and continuing use. Monte Carlo simulation was used to estimate possible ranges for these values. We used published estimates of cigar use and attributable mortality in the US, as well as prior study conclusions on the effect of local and national flavor restriction policies. We estimated that removal of flavored cigars would result in approximately 800 (90% prediction interval = 400–1200) fewer cigar smoking-attributable deaths in the US each year and 112,000 fewer cigar smokers (90% prediction interval = 76,000–139,000) in each cohort of 18 year olds. The removal of characterizing flavors in cigars sold in the US is thus projected to have substantial public health benefits over time.
Preference for flavoured cigar brands among youth, young adults and adults in the USA
BackgroundWhile cigarette consumption in the USA continues to decline, cigar consumption has increased. Tobacco-trade publications suggest that flavoured cigars are driving the recent growth in cigar consumption. Limited survey data exist to explore flavoured cigar preferences among youth and adults.MethodsThis study used the 2010–2011 National Survey on Drug Use and Health (NSDUH) and Nielsen market scanner data. The NSDUH sample consisted of 6678 past 30-day cigar smokers who reported smoking a usual brand of cigars. NSDUH contains a measure on usual cigar brand smoked and was merged with Nielsen data to estimate the per cent of each cigar brand's market share that is flavoured.ResultsMultivariate analyses indicate that youth, young adults, females, blacks, cigarette smokers, blunt users and daily cigar smokers are significantly more likely to report a usual cigar brand that is flavoured. Preference for a usual brand that produces flavoured cigars decreases significantly with age.ConclusionsThis study finds recent growth in flavoured cigar consumption and preference among youth and young adults for cigar brands that are flavoured. These findings underscore the need to expand monitoring of product attributes as well as individual-level cigar use behaviours captured through population surveillance.
E-Cigarette Market Trends in Traditional U.S. Retail Channels, 2012–2013
E-cigarette sales continue to increase in the United States. To date, little surveillance research has documented the specific product attributes driving growth. This study uses national market scanner data to describe sales trends in traditional U.S. tobacco retail channels between 2012 and 2013 and identifies product features associated with sales increases. Data on e-cigarette sales in convenience stores, drug stores, grocery stores, and mass merchandisers in the United States were obtained from the Nielsen Company. Each product was coded for attributes such as brand, flavor, and unit size. Total sales volume, market share, and percent growth were calculated for various product attributes. E-cigarette sales more than doubled between 2012 and 2013, from $273.6 million to $636.2 million, respectively. Growth was particularly strong in the convenience store channel. Blu eCigs quickly emerged as the best-selling brand and in 2013 constituted nearly half (44.1%) of overall sales. Although fruit-flavored and other flavored products experienced marked growth, unflavored and menthol e-cigarettes overwhelmingly dominated the market. Sales of single unit products (likely disposable e-cigarettes) increased by 216.4%, a much faster rate than multi-unit packs and cartridge refills. In traditional U.S. retail channels, particularly the convenience store channel, sales of e-cigarettes continue to grow, with brands like blu and disposable products as the likely drivers. Given the rapidly-changing market, expanded surveillance is needed to monitor sales not only in traditional retail locations, but sales online and in specialty \"vape shops,\" as well.
US Adult Cigar Smoking Patterns, Purchasing Behaviors, and Reasons for Use According to Cigar Type
The US cigar market is diverse, yet until recently most research studies and tobacco surveillance systems have not reported behavioral and related outcomes by cigar type. The 2013-2014 Population Assessment of Tobacco and Health Study collected data separately for filtered cigars (FCs), cigarillos, and traditional cigars, which were further distinguished as premium or nonpremium. Descriptive statistics for adult established current smokers of each cigar type and cigarettes were calculated for demographic characteristics, tobacco use patterns, purchasing behaviors and reasons for use. Adjusted prevalence ratios (APRs) using a marginal predictions approach with logistic regression assessed correlates of dual cigar and cigarette smoking. Age, sex, race/ethnicity, education level, and poverty status of smokers varied according to cigar type. Daily cigar smoking prevalence and number of cigars smoked per day were higher for FCs (37.3%; median: 1.6 cigars/day, respectively), than all other cigar types (6.7%-25.3%, all p < .01; 0.1-0.4 cigars/day, all p < .01, respectively); daily smoking and cigars per day were similar for nonpremium cigars and cigarillos (p = .11; p = .33, respectively). Cigarette smoking was twice as common among smokers of nonpremium cigars, cigarillos, and FCs (58.0%-66.0%) than among premium cigars (29.9%). Among current cigar smokers, FC smokers (APR = 1.23, 95% confidence interval [CI] = 1.09-1.39), other tobacco product users (APR = 1.27, 95% CI = 1.15-1.41), and those with a GED/high school diploma or less (APR = 1.20, 95% CI = 1.09-1.33) were more likely to also smoke cigarettes. User characteristics, cigar smoking patterns, and dual smoking with cigarettes varied by cigar type highlighting the importance of adequately describing the cigar type studied and, where appropriate, differentiating results by cigar type. Despite the diversity of the cigar market place, historically many research studies and tobacco surveillance systems have treated cigars as a single product type. This study describes similarities and differences in the user characteristics, tobacco use patterns, and purchasing behaviors of premium, nonpremium, cigarillo, and filtered cigar smokers. To enhance tobacco regulatory science, sufficient descriptions of the cigar type(s) studied and, where appropriate, differentiation of the particular cigar type(s) studied should be undertaken to improve the interpretation of study findings, understanding of cigar use patterns and related behaviors and future approaches to reducing cigar-attributable morbidity and mortality.
Flavored Tobacco Product Use Among Middle and High School Students — United States, 2014
The 2009 Family Smoking Prevention and Tobacco Control Act prohibits \"characterizing flavors\" (e.g., candy, fruit, and chocolate) other than tobacco and menthol in cigarettes; however, characterizing flavors are not currently prohibited in other tobacco products. Analyses of retail sales data suggest that U.S. consumption of flavored noncigarette tobacco products, including flavored cigars and flavored e-cigarettes, has increased in recent years. There is growing concern that widely marketed varieties of new and existing flavored tobacco products might appeal to youths (2) and could be contributing to recent increases in the use of tobacco products, including e-cigarettes and hookah, among youths. CDC and the Food and Drug Administration (FDA) analyzed data from the 2014 National Youth Tobacco Survey (NYTS) to determine the prevalence of past 30 day use (current use) of flavored e-cigarette, hookah tobacco, cigar, pipe tobacco or smokeless tobacco products, and menthol cigarettes among middle and high school students, and the proportion of current tobacco product users who have used flavored products. An estimated 70.0% (3.26 million) of all current youth tobacco users had used at least one flavored tobacco product in the past 30 days. Among current users, 63.3%, (1.58 million) had used a flavored e-cigarette, 60.6%, (1.02 million) had used flavored hookah tobacco, and 63.5% (910,000) had used a flavored cigar in the past 30 days. Given the millions of current youth tobacco users, it is important for comprehensive tobacco prevention and control strategies to address all forms of tobacco use, including flavored tobacco products, among U.S. youths.
Use of MR arthrography in detecting tears of the ligamentum teres with arthroscopic correlation
Objective To demonstrate the normal appearance of the ligamentum teres on MR arthrography (MRA) and evaluate the accuracy of MRA in detecting ligamentum teres tears with arthroscopic correlation. Materials and methods Institutional Review Board approval was obtained with a waiver for informed consent because of the retrospective study design. A total of 165 cases in 159 patients (111 females, 48 males; mean age 41 ± 12 years) who underwent both MRA and hip arthroscopy were evaluated for appearance of the ligamentum teres, including the size, number of bundles, and ligamentum teres tears. Marrow edema of the fovea capitis adjacent to the ligamentum teres insertion and the presence of hip plicae were also recorded. Results The mean thickness and length of the ligamentum teres were 3.5 ± 1.5 mm and 25.2 ± 3.8 mm, respectively. Sensitivity, specificity, positive and negative predictive value, and accuracy of MRA for the detection of ligamentum teres tears were 78, 97, 74, 97, and 95 %, respectively. Conclusion MRA is an accurate method to evaluate the normal morphology and to detect tears of the ligamentum teres.
Little Filtered Cigar, Cigarillo, and Premium Cigar Smoking Among Adults — United States, 2012–2013
The burden of death and disease from tobacco use in the United States has been caused overwhelmingly by cigarettes and other smoked tobacco products. In the United States, cigarette consumption declined during 2000-2011; however, consumption of cigars more than doubled during the same period. The cigar market includes diverse product types manufactured with a variety of shapes and sizes, filters, tips, flavors, and prices. Although national estimates of cigar consumption have been reported previously, data characterizing who smokes different cigar types are limited. A recent analysis from the 2012-2013 National Adult Tobacco Survey (NATS) found that more than one in 20 U.S. adults smoke cigars \"every day,\" \"someday,\" or \"rarely\". This report expands upon those findings, using data from the 2012-2013 NATS to further characterize cigar smokers by the usual type of cigar smoked using the following categories: little filtered cigars (LFCs), cigarillos/other mass market cigars (cigarillos/MMCs), and premium cigars. The findings indicate that among U.S. adults who smoke cigars, 61.8% usually smoke cigarillos/MMCs, 19.9% usually smoke premium cigars, and the remainder, 18.4%, usually smoke LFCs. These data can help to inform public health interventions to reduce the burden of adverse health effects caused by cigar smoking in the United States, including regulation.
