RESUMEN

INTRODUCTION: Flavors with names describing blended tastes/sensations or with ambiguous terminology ("concept flavors") are available on the e-cigarette market. AIMS AND METHODS: This study investigates adolescent and young adult use and sensory perceptions of blended and concept flavors. Current e-cigarette users aged 15-24 years (N = 2281) completed an online convenience sample survey (October 20-November 23, 2020) and rated the sensory attributes (fruity, cooling, sweet, and minty) of their current flavor(s) using nine-point scales. T-tests compared mean sensory perception scores within and between flavors. To compare concept flavors to blends, reference categories used the average of blends with relevant descriptors: fruit (Banana Ice, Iced Mango, Melon Ice, Cool Cucumber); cooling (Banana Ice, Iced Mango, Melon Ice, Blue B Ice, Cool Cucumber, Lush Ice, and Menthol Purple); sweet (Vivid Vanilla) and mint (Mint-sation). RESULTS: Most respondents had used at least one product with blended descriptors (74.8%) or concept flavor (57.9%) in the past 30 days. All flavors had high perceived strength for at least two sensory attributes. Mint taste was not perceived to be a strong sensory characteristic for all but two flavors (Mint-sation and Winter) in the study. The most commonly used flavors used blended descriptors (Iced Mango was used by 30.2% of the sample; Banana Ice: 26.2%; Lush Ice: 23.8%; Melon Ice: 22.9%). Some concept flavors did not significantly differ from flavor blend reference categories for strength of: fruit taste (Bahama Mama and Tropic); cooling sensation (Marigold, Island Breeze, Winter); sweet taste (Bahama Mama, Honeymoon, Island Breeze, Island Cream, Meteor Milk, OMG, Royal Dagger and Tropic); and mint taste (Winter). CONCLUSIONS: Blended and concept flavors are used by most young e-cigarette users, who describe these products as fruity, sweet, and cooling. A variety of flavored products with high youth appeal are available in the U.S. market. IMPLICATIONS: This study of adolescent and young adult e-cigarette users finds evidence of the popularity of e-cigarette flavors combining a cooling sensation with fruity and sweet flavorings. Some products with this flavor profile do not use characterizing descriptors. Findings inform public health interventions intended to reduce e-cigarette use in young people.

RESUMEN

OBJECTIVE: To use a standardised e-cigarette tax measure to examine the impact of e-cigarette taxes on the price and sales of e-cigarettes and cigarettes in the USA. DESIGN: We used State Line versions of NielsenIQ Retail Scanner data from quarter 4 of 2014 through quarter 4 of 2019 to calculate e-cigarette and cigarette prices and sales in 23 US states. We then estimated how these outcomes are associated with standardised state-level e-cigarette taxes, controlling for state fixed effects, quarter-by-year fixed effects, cigarette taxes, other tobacco control policies and other state-level time-varying characteristics. RESULTS: A real $1 increase in the e-cigarette standardised tax increases the price of 1 mL of e-liquid between $0.43 and $0.59 depending on specification. Controlling for fixed effects and cigarette taxes, a 10% increase in e-cigarette taxes is estimated to reduce e-cigarette sales by 0.5% and increase cigarette sales by 0.1%, though both results are attenuated and statistically insignificant in a model with full controls. CONCLUSIONS: Our study finds that e-cigarette taxes increase e-cigarette retail prices by approximately half of the tax. Further, e-cigarette taxes are associated with reduced sales of e-cigarettes and increased sales of cigarettes in some specifications. Our estimates are sizably lower than from other studies using sales and survey data.

RESUMEN

BACKGROUND: Flavored tobacco products are highly appealing to youth. The Federal government lacks a comprehensive flavored tobacco products policy and states have adopted different approaches restricting these products. This study analyzes the impact of Massachusetts' comprehensive prohibition and New Jersey's partial restriction on the sale of flavored tobacco products. METHODS: NielsenIQ Retail Scanner data were used to construct four log per capita dependent variables: e-liquid milliliters, cigarette packs, cigars, and smokeless tobacco ounces for products flavored as fruit, menthol, mint, tobacco and other. All models used difference-in-differences regressions, with Virginia and Pennsylvania serving as controls. The models controlled for state level product prices, population percentages by race/ethnicity, proportion male, median household income, unemployment rate, minimum legal sales age, tobacco 21 policies, and cumulative cases and deaths of COVID-19; the models accounted for time-specific factors by using 4-week period fixed-effects. RESULTS: There was a significant decrease in sales across all flavored tobacco products in Massachusetts, including fruit [-99.83%, p < 0.01], menthol [-98.33%, p < 0.01], and all other flavored [-99.28%, p < 0.01] e-cigarettes. The cigar group "all other-flavors" [-99.92%, p < 0.01] and menthol flavored cigarettes [-95.36%, p < 0.01] also significantly decreased. In New Jersey, there was a significant decrease in per capita sales of menthol-flavored e-cigarettes [-83.80%, p < 0.05] and cigar group "all other-flavors" experienced a significant increase in per capita sales [380.66%, p < 0.01]. CONCLUSIONS: This study contributes to the growing body of evidence demonstrating the impact of sales prohibitions on reducing sales of flavored tobacco products. Statewide comprehensive approaches appear more effective than partial restrictions and should be prioritized. IMPLICATIONS: Results from this study support emerging research that demonstrates the promising effects of comprehensive flavoring sales prohibitions. This study can be used to inform future flavored tobacco product policy solutions developed by advocates and policy makers to curb overall tobacco initiation and use by youth and adults.

RESUMEN

Oxidation of the neurotransmitter, dopamine (DA), is a pathological hallmark of Parkinson's disease (PD). Oxidized DA forms adducts with proteins which can alter their functionality. αB-crystallin and Hsp27 are intracellular, small heat-shock molecular chaperone proteins (sHsps) which form the first line of defense to prevent protein aggregation under conditions of cellular stress. In vitro, the effects of oxidized DA on the structure and function of αB-crystallin and Hsp27 were investigated. Oxidized DA promoted the cross-linking of αB-crystallin and Hsp27 to form well-defined dimer, trimer, tetramer, etc., species, as monitored by SDS-PAGE. Lysine residues were involved in the cross-links. The secondary structure of the sHsps was not altered significantly upon cross-linking with oxidized DA but their oligomeric size was increased. When modified with a molar equivalent of DA, sHsp chaperone functionality was largely retained in preventing both amorphous and amyloid fibrillar aggregation, including fibril formation of mutant (A53T) α-synuclein, a protein whose aggregation is associated with autosomal PD. In the main, higher levels of sHsp modification with DA led to a reduction in chaperone effectiveness. In vivo, DA is sequestered into acidic vesicles to prevent its oxidation and, intracellularly, oxidation is minimized by mM levels of the antioxidant, glutathione. In vitro, acidic pH and glutathione prevented the formation of oxidized DA-induced cross-linking of the sHsps. Oxidized DA-modified αB-crystallin and Hsp27 were not cytotoxic. In a cellular context, retention of significant chaperone functionality by mildly oxidized DA-modified sHsps would contribute to proteostasis by preventing protein aggregation (particularly of α-synuclein) that is associated with PD.

RESUMEN

BACKGROUND: Malaria in pregnancy is responsible for 8-14% of low birth weight and 20% of stillbirths in sub-Saharan Africa. To prevent these adverse consequences, the World Health Organization recommends intermittent preventive treatment of pregnant women (IPTp) with sulfadoxine-pyrimethamine be administered at each ANC visit starting as early as possible in the second trimester. Global IPTp coverage in targeted countries remains unacceptably low. Community delivery of IPTp was explored as a means to improve coverage. METHODS: A cluster randomized, controlled trial was conducted in 12 health facilities in a 1:1 ratio to either an intervention group (IPTp delivered by CHWs) or a control group (standard practice, with IPTp delivered at HFs) in three districts of Burkina Faso to assess the effect of IPTp administration by community health workers (CHWs) on the coverage of IPTp and antenatal care (ANC). The districts and facilities were purposively selected taking into account malaria epidemiology, IPTp coverage, and the presence of active CHWs. Pre- and post-intervention surveys were carried out in March 2017 and July-August 2018, respectively. A difference in differences (DiD) analysis was conducted to assess the change in coverage of IPTp and ANC over time, accounting for clustering at the health facility level. RESULTS: Altogether 374 and 360 women were included in the baseline and endline surveys, respectively. At baseline, women received a median of 2.1 doses; by endline, women received a median of 1.8 doses in the control group and 2.8 doses in the intervention group (p-value < 0.0001). There was a non-statistically significant increase in the proportion of women attending four ANC visits in the intervention compared to control group (DiD = 12.6%, p-value = 0.16). By the endline, administration of IPTp was higher in the intervention than control, with a DiD of 17.6% for IPTp3 (95% confidence interval (CI) - 16.3, 51.5; p-value 0.31) and 20.0% for IPTp4 (95% CI - 7.2, 47.3; p-value = 0.15). CONCLUSIONS: Community delivery of IPTp could potentially lead to a greater number of IPTp doses delivered, with no apparent decrease in ANC coverage.

RESUMEN

BACKGROUND: Adhesive small bowel obstruction (ASBO) severity has been associated with important clinical outcomes. However, the impact of ASBO severity on hospitalization cost is unknown. The American Association for the Surgery of Trauma (AAST) developed an Emergency General Surgery (EGS) disease severity grading system for ASBO. We stratified patients' ASBO severity and captured hospitalization costs hypothesizing that increased disease severity would correlate with greater costs. METHODS: This was a single-center study of hospitalized adult patients with SBO during 2015-2017. Clinical data and estimated total cost (direct + indirect) were abstracted. AAST EGS grades (I-IV) stratified disease severity. Costs were normalized to the median grade I cost. Univariate and multivariate analyses evaluated the relationship between normalized cost and AAST EGS grade, length of hospital and ICU stay, operative time, and Charlson comorbidity index. RESULTS: There were 214 patients; 119 (56%) were female. AAST EGS grades included: I (62%, n = 132), II (23%, n = 49), III (7%, n = 16), and IV (8%, n = 17). Relative to grade I, median normalized cost increased by 1.4-fold for grade II, 1.6-fold for grade III, and 4.3-fold for grade IV disease. No considerable differences in patient comorbidity between grades were observed. Pair-wise comparisons demonstrated that grade I disease cost less than higher grades (corrected p < 0.001). Non-operative management was associated with lower normalized cost compared to operative management (1.1 vs. 4.5, p < 0.0001). In patients who failed non-operative management, normalized cost was increased 7.2-fold. Collectively, the AAST EGS grade correlated well with cost (Spearman's p = 0.7, p < 0.0001). After adjustment for covariates, AAST EGS grade maintained a persistent relationship with cost. CONCLUSION: Increasing ASBO severity is independently associated with greater costs. Efforts to identify and mitigate costs associated with this burdensome disease are warranted. LEVEL OF EVIDENCE: III, economic/decision.

RESUMEN

Intussusception following Roux-en-Y gastric bypass is a rare, potentially life-threatening complication. Patients present with intermittent obstructive symptoms, and the diagnosis is made on imaging. Treatment is surgical considering the high likelihood of non-operative failure, strangulation, incarceration, perforation and concern for malignancy. We present the case of a woman in her 60s with a history of Roux-en-Y gastric bypass who presented with retrograde jejunojejunal intussusception at the distal Roux anastomosis. She proceeded to the operating room for complete anastomotic resection with reconstruction of three blind ends via two sequential isoperistaltic anastomoses. She progressed appropriately throughout her hospitalisation and was discharged on postoperative day 5 without recurrence. While intussusception in Roux-en-Y anatomy has been previously described, a literature review yielded sparse results in detailing its surgical correction. We highlight our unique surgical approach of jejunojejunal anastomotic resection with the creation of sequential isoperistaltic side-to-side anastomoses.

RESUMEN

BACKGROUND: Older adults presenting with trauma have worse outcomes than younger adults. Starting in 2016, we provided geriatrics consultation (GC) to older adults admitted to the trauma service. We aimed to analyze the impact of GC on patient outcomes. METHODS: We performed a retrospective pre-post study and year-matched cohort study. We identified patients from the trauma registry at our level 1 trauma center. In the pre-post study, we compared patients who received GC (2016-2022) with controls (2011-2015). In the cohort study (2016-2022), we compared patients who received GC with controls. We matched for age, race, sex, and injury severity score (ISS) in both studies, as well as admission year in the cohort study. Outcome variables included mortality (in-hospital, 30-day, 90-day), length of stay (LOS), discharge disposition, and hospital readmission rates (30-day, 90-day). RESULTS: We analyzed 1968 patients in the pre-post study and 2544 patients in the cohort study. Patients were similar in age, race, and sex. GC patients had a slightly higher ISS score and a higher rate of ICU stay. Delirium occurrence was lower among GC patients. GC patients had lower in-hospital mortality compared to controls (pre-post OR 0.27, p < 0.001; cohort OR 0.31, p < 0.001) and increased LOS (6 days vs 4 days, p < 0.001; both studies). GC patients in the cohort study also had lower 30- and 90-day mortality (OR 0.52 and 0.65, p < 0.01) and were less likely to return home (OR 0.81, p < 0.01); similar trends, though not statistically significant, were noted in the pre-post study. Lower readmission rates (statistically non-significant) were noted in the GC group across both studies. CONCLUSIONS: GC in older adults with trauma has proven benefit with reduced mortality and a trend toward lower readmission rates but was associated with increased LOS and higher rates of discharge to skilled facility.

RESUMEN

BACKGROUND: To describe the effect of the COVID-19 pandemic on emergency general surgery operative volumes during governmental shutdowns secondary to the pandemic and characterize differences in disease severity, morbidity, and mortality during this time compared to previous years. METHODS: This retrospective cohort study compares patients who underwent emergency general surgery operations at a tertiary hospital from March 1st to May 31st of 2020 to 2019. Average emergent cases per day were analyzed, comparing identical date ranges between 2020 (pandemic group) and 2019 (control group). Secondary analysis was performed analyzing disease severity, morbidity, and mortality. RESULTS: From March 1st to May 31st, 2020, 2.5 emergency general surgery operations were performed on average daily compared to 3.0 operations on average daily in 2019, a significant decrease (P = .03). No significant difference was found in presenting disease severity, morbidity, or mortality between the pandemic and control groups. DISCUSSION: This study demonstrates a decrease of 65% in emergency general surgery operations during governmental restrictions secondary to the COVID-19 pandemic. This decrease in operations was not associated with worse disease severity, morbidity, or mortality.

RESUMEN

BACKGROUND: The bromodomain and extraterminal protein (BET) inhibitor trotabresib has demonstrated antitumor activity in patients with advanced solid tumors, including high-grade gliomas. CC-90010-GBM-001 (NCT04047303) is a phase I study investigating the pharmacokinetics, pharmacodynamics, and CNS penetration of trotabresib in patients with recurrent high-grade gliomas scheduled for salvage resection. METHODS: Patients received trotabresib 30 mg/day on days 1-4 before surgery, followed by maintenance trotabresib 45 mg/day 4 days on/24 days off after surgery. Primary endpoints were plasma pharmacokinetics and trotabresib concentrations in resected tissue. Secondary and exploratory endpoints included safety, pharmacodynamics, and antitumor activity. RESULTS: Twenty patients received preoperative trotabresib and underwent resection with no delays or cancelations of surgery; 16 patients received maintenance trotabresib after recovery from surgery. Trotabresib plasma pharmacokinetics were consistent with previous data. Mean trotabresib brain tumor tissue:plasma ratio was 0.84 (estimated unbound partition coefficient [KPUU] 0.37), and modulation of pharmacodynamic markers was observed in blood and brain tumor tissue. Trotabresib was well tolerated; the most frequent grade 3/4 treatment-related adverse event during maintenance treatment was thrombocytopenia (5/16 patients). Six-month progression-free survival was 12%. Two patients remain on treatment with stable disease at cycles 25 and 30. CONCLUSIONS: Trotabresib penetrates the blood-brain-tumor barrier in patients with recurrent high-grade glioma and demonstrates target engagement in resected tumor tissue. Plasma pharmacokinetics, blood pharmacodynamics, and safety were comparable with previous results for trotabresib in patients with advanced solid tumors. Investigation of adjuvant trotabresib + temozolomide and concomitant trotabresib + temozolomide + radiotherapy in patients with newly diagnosed glioblastoma is ongoing (NCT04324840).

RESUMEN

OBJECTIVE: To determine differences in plasma sex hormone levels in male and female coronavirus disease 2019 (COVID-19) patients and healthy volunteers (HVs) because cell entry of severe acute respiratory syndrome coronavirus 2 occurs via the angiotensin-converting enzyme 2 receptor which is downregulated by 17ß-estradiol. PATIENTS AND METHODS: Citrated plasma samples were collected from 101 patients with COVID-19 upon presentation to the emergency department and from 40 HVs between November 1, 2020, and May 30, 2021. Plasma 17ß-estradiol and 5α-dihydrotestosterone (DHT) levels were measured using enzyme-linked immunosorbent assay (pg/mL). Data are presented as median and quartiles (IQR). Wilcoxon rank sum test with a P value less than .05 was considered significant. RESULTS: Patients with COVID-19 (median age, 49 years) included 51 males and 50 females (25 postmenopausal). Hospital admission was required for 58.8% of male patients (n = 30) and 48.0% of female patients (n = 24) (66.7% postmenopausal, n = 16) Healthy volunteers (median age, 41 years) included 20 males and 20 females (9 postmenopausal). Female patients with COVID-19 were found to have decreased 17ß-estradiol levels (18.5 [IQR, 10.5-32.3] pg/mL; 41.4 [IQR, 15.5-111.0] pg/mL, P=.025), and lower 17ß-estradiol to DHT ratios (0.073 [IQR, 0.052-0.159] pg/mL; 0.207 [IQR, 0.104-0.538] pg/mL, P=.015) than female HVs. Male patients with COVID-19 were found to have decreased DHT levels (302.8 [IQR, 249.9-470.8] pg/mL; 457.2 [IQR, 368.7-844.3] pg/mL, P=.005), compared with male HVs. Levels of DHT did not differ between female patients with COVID-19 and female HVs, whereas 17ß-estradiol levels did not differ between male patients with COVID-19 and male HVs. CONCLUSION: Sex hormone levels differ between patients with COVID-19 and HVs, with sex-specific patterns of hypogonadism in males and females. These alterations may be associated with disease development and severity.

RESUMEN

INTRODUCTION: We used interrupted time series (ITS) analysis to determine whether e-scooter shares' introduction in September 2017 increased serious scooter-related injury across the United States. METHODS: Using the National Electronic Injury Surveillance System, we queried emergency department visits involving motorized scooter-related injuries from January 2010-December 2019. Cases originating where e-scooter shares launched between September 1, 2017-December 1, 2019 (intervention period) were considered exposed. The first month of launch (September 2017) was chosen as the time point for pre- and post-intervention analysis. The primary outcome was change in hospitalizations following scooter injury in association with the month/year launch. RESULTS: This analysis includes 2754 unweighted encounters, representing 102614 estimated injuries involving motorized scooters nationwide. Hospitals within 20 miles of e-scooter shares also experienced a significant monthly increase of 0.24 scooter-related injury hospitalizations/1000 product-related injury hospitalizations ([0.17,0.31]) compared to a non-significant change in hospitalizations of 0.02 [-0.05,0.09] for control hospitals. CONCLUSION: An increase in serious motorized scooter injuries coincides with e-scooter shares' introduction in the US. Future works should explore effective polices to improve public safety.

RESUMEN

Left ventricular assist devices (LVADs) have revolutionized the management of patients with advanced heart failure refractory to medical therapy. Current indications of LVADs include Bridge to Transplantation (BTT), Destination Therapy (DT) for long-term use, Bridge to the Decision (BTD) used as a temporary measure, and lastly Bridge to Recovery (BTR). Here, we briefly review the clinical evidence and the molecular mechanisms behind myocardial recovery following LVAD placement. We also share institutional protocols used at 2 major medical centers in the USA.

RESUMEN

BACKGROUND: There are limited studies regarding the impact of post-operative leak on perforated peptic ulcer disease (PPUD) and conflicting results regarding routine drain placement in operative repair of PPUD. This study aims to identify risk factors for gastrointestinal leak after operative repair of PPUD to better guide intra-operative decisions about drain placement. METHODS: We performed a retrospective cohort study at a tertiary care center from 2008 to 2019, identifying 175 patients who underwent operative repair of PPUD. RESULTS: Patients who developed a leak (17%) were compared to patients who did not. Both hypoalbuminemia (albumin < 3.5 g/dL) (P = .03) and duodenal ulcers (P < .01) were identified as significant risk factors for leak. No significant difference was found between leak and no leak groups for AAST disease severity grade, repair technique, or pre-operative use of tobacco, alcohol, or steroids. Post-operative leaks were associated with prolonged hospital stay (29 days compared to 10, P < .01), increased complication rates (77% compared to 48%, P < .01), and increased re-operation rates (73% compared to 26%, <0.01). No difference was identified in patient characteristics or operative leak rates between patients who had drains placed at the index operation and those that did not. DISCUSSION: Leak after operative PPUD repair is associated with significant post-operative morbidity. Hypoalbuminemia and duodenal perforations are significant risk factors for post-operative leaks.

RESUMEN

BACKGROUND: The 2019 novel coronavirus disease (COVID-19) pandemic led many jurisdictions to close in-person school instruction. METHODS: We collected data about COVID-19 cases associated with New York City (NYC) public schools from polymerase chain reaction testing performed in each school on a sample of asymptomatic students and staff and from routine reporting. We compared prevalence from testing done in schools to community prevalence estimates from statistical models. We compared cumulative incidence for school-associated cases to all cases reported to the city. School-based contacts were monitored to estimate the secondary attack rate and possible direction of transmission. RESULTS: To assess prevalence, we analyzed data from 234 132 persons tested for severe acute respiratory syndrome coronavirus 2 infection in 1594 NYC public schools during October 9 to December 18, 2020; 986 (0.4%) tested positive. COVID-19 prevalence in schools was similar to or less than estimates of prevalence in the community for all weeks. To assess cumulative incidence, we analyzed data for 2231 COVID-19 cases that occurred in students and staff compared with the 86 576 persons in NYC diagnosed with COVID-19 during the same period; the overall incidence was lower for persons in public schools compared with the general community. Of 36 423 school-based close contacts, 191 (0.5%) subsequently tested positive for COVID-19; the likely index case was an adult for 78.0% of secondary cases. CONCLUSIONS: We found that in-person learning in NYC public schools was not associated with increased prevalence or incidence overall of COVID-19 infection compared with the general community.

RESUMEN

The US opioid epidemic is a serious public health problem. Rates of opioid misuse and dependence are highest for young adults ages 18-25. Prevention strategies that reduce prescription opioid misuse while decreasing stigma around dependence and treatment are critical components of addressing the epidemic. The Truth About Opioids, a mass media public education campaign, was designed to prevent opioid misuse and dependence among young adults. This study examined the intervention's effectiveness to shift opioid-related knowledge, attitudes, and beliefs within targeted designated market areas (DMAs) over time. A sample of young adults (N = 1434) in DMAs with varying levels of media exposure was surveyed at baseline (June-September 2019) and post-intervention (July-August 2020). Logistic regression assessed associations between campaign awareness and campaign-targeted knowledge and attitudes, controlling for baseline variables. Those with any awareness had significantly higher odds of campaign-targeted opioid-related knowledge (versus no awareness) (low awareness OR = 1.52 (95% CI: 1.04, 2.24); high awareness OR = 2.47 (95% CI: 1.58, 3.87)). Those with campaign awareness were also more likely to report lower levels of opioid-related stigma and higher intentions to share information and talk to a friend about the epidemic. Mass media public education campaigns can help influence young adults' opioid-related knowledge and attitudes.

RESUMEN

While youth and young adult e-cigarette use has risen in the U.S., few studies have explored e-cigarette cessation behavior. This study estimates quit attempts and intentions among young people (aged 15-36) since the rise of high-nicotine products, and examines factors associated with e-cigarette quit attempts and intentions. Current e-cigarette users (past 30-day use, not already quit) were drawn from a national probability-based cohort sample. Data were collected from September to December 2019 (n = 1158). Weighted proportions of past-year quit attempts, intentions to quit in next 30 days, and general intentions to quit (at some point) were calculated. Models estimated cessation outcomes with respect to harm perceptions, friend use, dependence, use frequency, combustible use and demographic factors. Among current e-cigarette users, 54.2% reported general intentions to quit, 15.3% reported intention to quit within 30 days, and 33.3% reported a past-year quit attempt. Past-year quit attempts were associated with higher levels of harm perceptions (adjusted odds ratio (aOR) = 2.08, 95% confidence interval (CI): 1.49-2.92), dependence (aOR = 1.92, 95% CI: 1.44-2.56) and daily use (28 + days) compared to infrequent use (1-5 days) (aOR = 0.23, 95% CI: 0.12-0.43). General intentions to quit were positively associated with harm perceptions (aOR = 1.77, 95% CI: 1.23-2.56) and dependence (aOR = 1.89, 95% CI: 1.41-2.52), and negatively associated with daily use compared to infrequent use (aOR = 0.35, 95% CI: 0.19-0.65). Findings indicate that over half of young e-cigarette users want to quit, highlighting a critical need for policies and resources to promote and sustain e-cigarette cessation among young people.

RESUMEN

OBJECTIVE: Describe workplace vaping, prevalence of observed use, attitudes, and perceptions among US adults. METHODS: Employees of companies with more than 150 employees, drawn from an opt-in national online panel (N = 1607), ages 18 to 65, completed an online survey in November 2019. RESULTS: Majority (61.6%) observed coworkers vaping at work and 19.1% reported vaping at work themselves. Participants perceived workplace vaping as moderately harmful (M = 1.9 out of 3), 63.2% were bothered by workplace vaping and 52.1% thought it decreased workplace productivity among non-users. Multiple regression models found workplace vaping prevalence varied by industry and participant characteristics, and attitudes about it varied by tobacco use status. CONCLUSIONS: Workplace vaping and vaping exposure is common in US workplaces. Employees, particularly non-users, hold generally negative perceptions of workplace vaping. Comprehensive policies to prevent workplace vaping are needed to protect workers.

RESUMEN

INTRODUCTION: Plasma thrombin generation kinetics as measured by the calibrated automated thrombogram (CAT) assay is a predictor of symptomatic venous thromboembolism after trauma. We hypothesized that data from a new prototype assay for measurement of thrombin generation kinetics in fresh whole blood (near patient testing of thrombin generation), will correlate with the standard CAT assay in the same patients, making it a potential tool in the future care of trauma patients. METHODS: Patients were enrolled from June 2018 to February 2020. Within 12 hours of injury, blood samples were collected simultaneously for both assays. Variables compared and correlated between assays were lag time, peak height, time to peak, and endogenous thrombin potential. Data are presented as median with interquartile range (IQR). Spearman and Pearson correlations were estimated and tested between both assays; a P value of <0.05 was considered to be significant. RESULTS: A total of 64 trauma patients had samples analyzed: injury severity score = 17 (IQR), 10-26], hospital length of stay = 7.5 (IQR), 2-18) days, age = 52 (IQR, 35-63) years, 71.9% male, and 42.2% of patients received a transfusion within 24 hours of injury. Thrombin generation parameters between plasma and whole blood were compared and found that all parameters of the two assays correlate in trauma patients. CONCLUSION: In this pilot study, we have found that a novel point-of-care whole blood thrombin generation assay yields results with modest but statistically significant correlations to those of a standard plasma thrombin generation assay. This finding supports studying this device in a larger, adequately powered study.
