The Contribution of Organised Leisure-Time Activities in Shaping Positive Community Health Practices among 13-and 15-Year-Old Adolescents: Results from the Health Behaviours in School-Aged Children Study in Italy.

Background and Objective: Participation in organised out-of-school leisure-time activities (OLTAs) has been shown to have a positive impact on community health practices and to lessen inequities in social and environmental opportunities among youths. According to the social capital theory, OLTAs foster bridging ties that allow individuals to forge new, wider-ranging social connections, increasing social integration and opportunities for identity-related exploration. This study aimed to describe participation in different types of OLTAs and its association with perceived life satisfaction, physical activity, tobacco use, alcohol consumption, and drunkenness in a representative sample of youths. Methods: A representative sample of 11-, 13- and 15-year-old students (n = 47,799) was recruited throughout all Italian regions within the Italian 2013/2014 Health Behaviours in School-aged Children (HBSC) study. Data were collected according to the HBSC study protocol. Participants were compared on outcomes according to OLTA participation type (i.e., non-sport, sport-only, and mixed vs. no-OLTA). In accordance with the study sampling procedures, hierarchical logistic regression models were used. Results: Participation in OLTAs was significantly associated with high life satisfaction in all ages (sport-only: odds ratio (OR) = 1.67, 1.48 and 1.55 for 11- 13- and 15-year-olds; mixed: OR = 1.95, 1.60 and 1.45, respectively). Youths participating in OLTAs were more likely to meet physical activity recommendations and report lower rates of tobacco use and drunkenness. Conclusions: Participation in OLTAs showed a favourable impact on health behaviours. Thus, community organisations and clubs, whether supported by public investments, could contribute to the enhancement of beneficial health practices, by engaging and serving the community as a whole and further reducing inequities in both social and environmental opportunities.

Impact of perforator sparing on anterior component separation outcomes in open abdominal wall reconstruction.

Anterior component separation (ACS) is a well-established, highly functional technique to achieve fascial closure in complex abdominal wall reconstruction (AWR). Unfortunately, ACS is also associated with an increased risk of wound complications. Perforator sparing ACS (PS-ACS) has more recently been introduced to maintain the subcutaneous perforators derived from the deep epigastric vessels. The aim of this study is to evaluate wound-related outcomes in patients undergoing open AWR after implementation of a PS-ACS technique. A prospectively collected database were queried for patients who underwent open AWR and an ACS from 2006 to 2018. Patients who underwent PS-ACS were compared to patients undergoing ACS using standard statistical methods. Patients undergoing concomitant panniculectomy were included in the standard ACS group. In total, 252 patients underwent ACS, with 24 (9.5%) undergoing PS-ACS. Age and specific comorbidities were similar between groups (all p > 0.05) except for the PS-ACS groups having a higher rate of prior tobacco use (45.8% vs 19.6%, p = 0.003). Mean hernia defect area was 381.6 ± 267.0 cm2 with 64.3% recurrent hernias, and both were similar between groups (all p > 0.05). The PS-ACS group did have more complex wounds with more Ventral Hernia Working Group Grade 3 and 4 hernias (p = 0.04). OR time and length of stay were similar between groups (all p > 0.05). Despite increased complexity, wound complication rates were much lower in the PS-ACS group (20.8% vs 46.1%, p = 0.02), and all specific wound complications were lower but not statistically different. Hernia recurrence rate was similar between PS-ACS and ACS groups (4.2% vs 7.0%, p > 0.99) with mean follow-up of 27.7 ± 26.9months. In complex AWR, preservation of the deep epigastric perforating vessels during ACS significantly lowers the rates of wound complications, despite its performance in more complex patients with an increased risk of infection. PS-ACS should be performed preferentially over a standard ACS whenever possible.

Barriers to palliative care in sexual and gender minority patients with cancer: A scoping review of the literature.

The Institute of Medicine reports lesbian, gay, bisexual and transgender (LGBT) individuals having the highest rates of tobacco, alcohol and drug use leading to elevated cancer risks. Due to fear of discrimination and lack of healthcare practitioner education, LGBT patients may be more likely to present with advanced stages of cancer resulting in suboptimal palliative care. The purpose of this scoping review is to explore what is known from the existing literature about the barriers to providing culturally competent cancer-related palliative care to LGBT patients. This review will use the five-stage framework for conducting a scoping review developed by Arksey and O'Malley. The PubMed, Scopus, PsychINFO and Cochrane electronic databases were searched resulting in 1,442 citations. Eligibility criteria consisted of all peer-reviewed journal articles in the English language between 2007 and 2020 resulting in 10 manuscripts. Barriers to palliative cancer care for the LGBT include discrimination, criminalisation, persecution, fear, distress, social isolation, disenfranchised grief, bereavement, tacit acknowledgment, homophobia and mistrust of healthcare providers. Limited healthcare-specific knowledge by both providers and patients, poor preparation of legal aspects of advanced care planning and end-of-life care were underprovided to LGBT persons. As a result of these barriers, palliative care is likely to be provided for LGBT patients with cancer in a deficient manner, perpetuating marginalisation and healthcare inequities. Minimal research investigates these barriers and healthcare curriculums do not provide practitioners skills for administering culturally sensitive palliative care to LGBT patients.

Sexual Orientation, Tobacco Use, and Tobacco Cessation Treatment-Seeking: Results From a National U.S. Survey

Despite higher rates of tobacco use and smoking-related diseases among sexual minorities, tobacco cessation treatment-seeking behaviors (e.g., medication, nicotine replacement products) remain poorly understood across sexual orientation subgroups. This study examines tobacco cessation treatment-seeking behaviors associated with Diagnostic and Statistical Manual of Mental Disorders, 5th Edition tobacco use disorder (TUD) across the three major sexual orientation dimensions (identity, attraction, behavior) in U.S. adults. Prevalence estimates reflect data collected from a 2012–2013 national sample of adults 18 years and older. More than three-fourths of U.S. adults with TUD had never engaged in tobacco cessation treatment-seeking behaviors, regardless of sexual orientation. Despite having the highest rates of TUD, bisexual men and women had some of the lowest rates of tobacco cessation treatment-seeking. Men who identified as gay, reported same-sex attraction, or reported same-sex behaviors had the highest rates of tobacco cessation treatment-seeking. In contrast, women with same-sex attraction or same-sex behavior had higher rates of TUD but were less likely to engage in tobacco cessation treatment-seeking behaviors than women with only other-sex attraction or other-sex behavior, respectively. Heterosexual women were more likely to engage in tobacco cessation treatment-seeking than heterosexual men; this sex difference was not present for sexual minorities. Medications and nicotine replacement therapy products were the most prevalent forms of treatment-seeking. There were notable differences in tobacco cessation treatment-seeking behaviors based on sex and sexual orientation. Findings highlight the underutilization of tobacco cessation treatment-seeking among all U.S. adults and point to important factors to consider when working with sexual minorities who are trying to reduce or stop using tobacco.

Identification and characterization of older emergency department patients with high-risk alcohol use.

BackgroundHigh‐risk alcohol use in the elderly is a common but underrecognized problem. We tested a brief screening instrument to identify high‐risk individuals.MethodsThis was a prospective, cross‐sectional study conducted at a single emergency department. High‐risk alcohol use was defined by National Institute on Alcohol Abuse and Alcoholism (NIAAA) guidelines as >7 drinks/week or >3 drinks/occasion. We assessed alcohol use in patients aged ≥ 65 years using the timeline follow back (TLFB) method as a reference standard and a new, 2‐question screener based on NIAAA guidelines. The Alcohol Use Disorders Identification Test (AUDIT) and Cut down, Annoyed, Guilty, Eye‐opener (CAGE) screens were used for comparison. We collected demographic information from a convenience sample of high‐ and low‐risk drinkers.ResultsWe screened 2250 older adults and 180 (8%) met criteria for high‐risk use. Ninety‐eight high‐risk and 124 low‐risk individuals were enrolled. The 2‐question screener had sensitivity of 98% (95% CI, 93%–100%) and specificity of 87% (95% CI, 80%–92%) using TLFB as the reference. It had higher sensitivity than the AUDIT or CAGE tools. The high‐risk group was predominantly male (65% vs 35%, P < 0.001). They drank a median of 14 drinks per week across all ages from 65 to 92. They had higher rates of prior substance use treatment (17% vs 2%, P < 0.001) and current tobacco use (24% vs 9%, P = 0.004).ConclusionA rapid, 2‐question screener can identify high‐risk drinkers with higher sensitivity than AUDIT or CAGE screening. It could be used in concert with more specific questionnaires to guide treatment.

Building Momentum for Tobacco Control in the Western Pacific Region

The tobacco epidemic is a significant global public health threat, killing more than eight million people a year around the world. Although the average rate of tobacco use in the Western Pacific Region (WPR) is declining over time in accordance with global trends, the region is experiencing the slowest decline of all six WHO regions. Around 12% of boys aged 13-15 and 4% of girls in the same age group are current tobacco users in WPR. The fact that nearly six million children use tobacco products at the young age of 13-15 is cause for concern. With the COVID-19 pandemic affecting many countries globally, now is an opportune time to reduce tobacco use. Tobacco data collection, which is the focus of this special supplement, plays a key role in understanding the magnitude, patterns, determinants and consequences of tobacco use and exposure. Good monitoring tracks the extent and character of the tobacco epidemic and indicates how best to tailor policies. The findings and lessons from this special supplement provide a welcome contribution to the progress made in global tobacco control and a testament to the efforts and dedication of countries across the Western Pacific Region to fighting the tobacco epidemic.

A Global View on Prevalence of Hypertension and Human Develop Index.

Background:The incidence of hypertension has been increasing in the past decade. Little is known regarding the relationship between hypertension and human development index (HDI).Objectives:The objective is to identify the relationship between the prevalence of hypertension and human development index (HDI).Methods:An ecological study was conducted. The data from World Health Organization reports and United Nations Development Programme reports for 182 countries, including the HDI values, rates of tobacco use, physical inactivity, alcohol use, and salt intake. The Generalized Additive Models were implemented to assess the association between the prevalence of hypertension and the HDI.Results:Among 182 countries, the prevalence of hypertension ranged from 13% to 41%. The highest HDI value was 0.949 and the lowest was 0.352. In model 1, statistically significant associations were found in three populations, the largest R2 was 0.245. In model 2, the largest R2 was 0.485. In linear part, there was negative relationship in female population, while HDI was associated with prevalence of hypertension in all three populations, which was explained by spline function. The curve indicated that there were three intervals from low to high HDI. From 0 to 0.6 and 0.8 to 1, an evident decreasing trend of prevalence was found, while the rate increased when HDI was in the interval of 0.6 to 0.8.Conclusions:In this study, we identified the association between the prevalence of hypertension and the HDI and the underlying pattern of the relationship. The findings will aid the planning of hypertension control priorities and provide suggestions for interventions.

Sexual Identity Differences in Health Behaviors and Weight Status among Urban High School Students

Although racial/ethnic disparities in childhood obesity are well documented in the United States (U.S.), fewer studies have investigated elevated body mass index (BMI) and related health behaviors among sexual minority youth (SMY; gay/lesbian, bisexual, not sure). We examined pooled data from the 2009-2017 Youth Risk Behavior Surveys, which included high school students from 12 urban U.S. school districts. We used sex-stratified logistic regression models to estimate the association of sexual identity with health behaviors and elevated BMI (reference = heterosexual participants). A total of 133,615 participants were included. Sexual minority boys were more likely to report physical inactivity than heterosexual boys. Gay and not sure boys were also less likely to consume the recommended daily intake of fruit. Bisexual girls were more likely than heterosexual girls to report watching television ≥ 3 hours on a school day and to consume sugar-sweetened beverages (AOR 1.30, 95% CI= 1.18-1.43). All SMY reported higher rates of current tobacco use than their heterosexual peers. Sexual minority girls and bisexual boys had significantly higher rates of obesity than their heterosexual counterparts. These findings can inform tailored health promotion initiatives to reduce obesity risk in SMY.

Global Burden of Head and Neck Cancer.

Head and neck cancer is increasing globally owing to rising rates of tobacco use and human papillomavirus infection. Today, cancer is the leading cause of death and disabilities in developed countries and the second leading cause of death in countries with developing economies. Understanding the global landscape of head and neck cancer will empower oral and maxillofacial surgeons to play a critical role among patients and societal education regarding the importance of addressing modifiable risk factors and continuing to play an important role in the diagnosis and management of head and neck cancer.

A Smoking Prevention Program for Aboriginal Youth

In recent years, policymakers and medical experts have expressed alarm about the growing problem of tobacco related deaths, most specifically from smoking cigarettes. Even more alarming is the rate of tobacco use among Aboriginal people and specifically Aboriginal youth. This paper explores how a holistic approach coupled with Aboriginal healthcare professionals is necessary for an effective smoking prevention program. Moreover, recommendations are provided based on this information to help devise an effective smoking prevention program encompassing all four aspects of health; mental, physical, emotional and spiritual.

Effects of chronic nicotine exposure on Δ9-tetrahydrocannabinol-induced locomotor activity and neural activation in male and female adolescent and adult rats

RationaleHigh rates of comorbid tobacco and cannabis use in adolescents and young adults may be related to functional interactions between the nicotinic cholinergic and cannabinoid systems in the brain during development. This study examined the effects of chronic exposure to nicotine (the psychoactive component in tobacco) on acute exposure to delta-9-tetrahydrocannabinol (THC) (the psychoactive component of cannabis). MethodsMale and female adolescent and adult Sprague-Dawley rats (N = 112) were injected daily with nicotine (1 mg/kg, i.p.) or vehicle for 14 days, followed by a 14-day drug-free period. On test day, rats were injected with THC (5 mg/kg, i.p.) or vehicle, locomotor activity was recorded for 2 h, and brains harvested for c-Fos immunoreactivity (IR). ResultsLocomotor activity and c-Fos IR changes induced by THC challenge were altered by nicotine pre-exposure and modified by age and sex. THC-induced suppression of locomotor activity was attenuated by nicotine pre-exposure in adult but not adolescent males. THC-induced suppression of locomotor activity was potentiated by nicotine pre-exposure in female adolescents, with no effects of THC or nicotine observed in female adults. THC increased c-Fos IR in the caudate, nucleus accumbens, stria terminalis, septum, amygdala, hypothalamus, and thalamus. Nicotine pre-exposure potentiated this effect in all regions. Several brain regions showed age and sex differences in c-Fos IR such that expression was greater in adults than adolescents and in females than males. ConclusionsChronic nicotine pre-exposure produces lasting effects on cannabinoid-mediated signalling in the brain and on behaviour that are mediated by age and sex. Funding supportNSERC.

Anogenital High-Grade Squamous Intraepithelial Lesion Comorbid With Vulvar Lichen Sclerosus and Lichen Planus.

The aim of the study was to describe the clinicopathologic features of vulvovaginal or anal high-grade squamous intraepithelial lesion (HSIL) comorbid with lichen sclerosus and/or lichen planus (LS/LP). The local pathology database identified 37 consecutive cases from 2007 to 2019 of vulvar, vaginal, or anal HSIL among women who had a histopathologic diagnosis of vulvar LS/LP. Cases had p16 and p53 immunoperoxidase stains. Clinical data included age, relative location of HSIL and LS/LP, immune-modifying conditions, tobacco use, treatment type, and follow-up. Histopathologic data included HSIL morphology categorized as warty-basaloid or keratinizing, p16 and p53 patterns within HSIL, and features of LS/LP. The mean age was 69 years with a median follow-up up 42 months. Lichen sclerosus, alone or in combination with LP, was the comorbid dermatosis in 89%. Lichen sclerosus/lichen planus was overlapping or adjacent to HSIL in two-thirds of cases and located separately in the remainder. Rates of tobacco use and immunologic dysfunction were each 40%. In cases of co-located LS and HSIL, sclerosis was absent under the neoplasia in 57%. Twenty-four percent of HSIL cases showed keratinizing morphology; block-positive p16 and suprabasilar-dominant p53 helped distinguish HSIL from human papillomavirus-independent neoplasia. Histopathologic identification of comorbid HSIL and LS/LP may be challenging because of keratinizing morphology and loss of diagnostic features of LS. Clinicopathologic correlation and use of p16 and p53 are essential to achieve an accurate diagnosis and enact disease-specific management plans.

Cancer Perceptions Among Smokeless Tobacco Users: A Qualitative Study of US Firefighters.

BackgroundPrevalence rates of smokeless tobacco (SLT) use among firefighters are remarkably high and substantially higher than similar occupational groups and the general U.S. population. The purpose of this study was to explore the perspectives of fire service personnel regarding cancer and its associations with tobacco and SLT use.MethodsThis descriptive study used a qualitative approach. Key informant interviews were conducted in 39 career firefighters and fire service administration from across the U.S. Discussion were recorded, transcribed verbatim and transferred to NVivo software for narrative analysis. Topics explored included cancer perceptions, attitudes and beliefs, and cultural factors related to SLT use behaviors. Results: Major themes that emerged among fire service personnel included concerns about cancer and its risk factors including firefighting tasks, such as fire overhaul operations, and from their lifestyle behaviors, such as alcohol and tobacco use. Firefighters also suggested a number of reasons for their increased SLT use, such as fire department tobacco-free policy and fire service culture.ConclusionThe current study provides a rich foundation for future research, prevention, and intervention efforts for the fire service and research communities regarding tobacco and SLT use and cancer risk. Additional research on firefighters' cancer beliefs deserves future research in order to improve messaging about the risks of cancer due to firefighting.

Baseline characteristics of American Indian smokeless tobacco users participating in two pilot cessation studies.

American Indians have higher rates of smokeless tobacco (SLT) use than other racial/ethnic groups in the US, yet no efficacious cessation program exists for them. Because tobacco is a sacred plant to many American Indians, it is imperative that a program respect the scared nature of tobacco while encouraging quitting recreational use. All Nations Snuff Out Smokeless (ANSOS) was designed to help American Indian SLT users quit recreational tobacco use while still using it for traditional purposes. We pilot tested the ANSOS 6-month group-based counseling program (N = 48) and a shortened version consisting of a one-time education session (N = 80). Here, we discuss the tobacco characteristics of participants at baseline in both studies. Participants across studies were more likely to be male (74.2%) and have at least a college education (65%). Participants in the one-time education sessions were younger (age 35 vs age 39) and used SLT fewer days per week (4.9 vs 5.7). Two-thirds of those in the full program reported that they often substitute SLT in locations where smoking is not allowed compared to 26%. Participants in the education sessions were more likely to report daily use of traditional tobacco (20% versus 0%). Results suggest that dual use of SLT and cigarettes needs to be addressed, as does the use of SLT to circumvent public smoking rules. The role of traditional tobacco and its relationship to lower SLT use also warrants further investigation.

Predictive model for the diagnosis of benign/malignant small pulmonary nodules.

There is some doubt that all nodules <8 mm are really mainly benign and that simple follow-up is adequate in all cases. The purpose of this study is to create a predictive model for the diagnosis of benign and malignant small pulmonary nodules.This was a retrospective case–control study of patients who had undergone pulmonary nodule resection at the Zhejiang University Jinhua Hospital. Patients with pulmonary nodules of ≤10 mm in size on chest high-resolution computed tomography were included. Patients’ demographic characteristics, clinical features, and high-resolution computed tomography findings were collected. Logistic regression and receiver-operating characteristic analysis were used to create a predictive model for malignancy.A total of 216 patients were included: 160 with malignant and 56 with benign nodules. Nodule density (odds ratio [OR] = 0.996, 95% confidence interval [CI]: 0.993–0.998, P = .001), vascular penetration sign (OR = 3.49, 95% CI: 1.39–8.76, P = .008), nodule type (OR = 4.27, 95% CI: 1.48–12.29, P = .007), and incisure surrounding nodules (OR = 0.18, 95% CI: 0.04–0.84, P = .03) were independently associated with malignant nodules. These factors were used to create a mathematical model that had an area under the receiver-operating characteristic curve of 0.744. Using a cut-off of 0.762 resulted in 63.1% sensitivity and 75.0% specificity.This study proposes a pulmonary nodule prediction model that can estimate benign/malignant lung nodules with good sensitivity and specificity. Mixed ground-glass nodules, vascular penetration sign, density of lung nodules, and the absence of incisure signs are independently associated with malignant lung nodules.

Low-Income Female Students and the Reversal of the Black-White Gap in High School Graduation

This article shows that the traditional narrative of Black-White high school graduation gaps is inverted among economically disadvantaged female students. Two nationally representative surveys and statewide administrative data demonstrate that low-income White females graduate at rates 5 to 6 percentage points lower than Black peers despite having higher test scores. Greater rates of tobacco, alcohol, and illicit drug use among White females account for one third of the attainment disparity. Since the early onset of substance use among low-income White females predicts lower attainment, more research on the factors leading to risky behaviors and their correlates during early adolescence is warranted. Examining racial gaps in high school graduation at the intersection of gender and income categories can inform more tailored interventions.

Mental health consequences for survivors of the 2011 Fukushima nuclear disaster: a systematic review. Part 2: emotional and behavioral consequences.

To compile the findings of studies assessing emotional and behavioral changes in the survivors of the 2011 Fukushima nuclear disaster, we performed a systematic review in August 2019 using four literature databases (PubMed, PsycINFO, Psychology and Behavioral Sciences Collection, and ICHUSHI). Peer-reviewed manuscripts, either in English or Japanese, were included in the searches. Sixty-one studies were retrieved for the review. Of these, 41 studies (67.2%) assessed emotional consequences, 28 studies (45.9%) evaluated behavioral consequences, and 8 studies (13.1%) evaluated both emotional and behavioral outcomes. The main research topic in emotional change was radiation exposure-associated risk perception, as reported in 15 studies. This risk perception included immediate health effects (eg, acute radiation syndrome) as well as future health effects (eg, future cancer and genetic effects). Lowered subjective well-being was reported in eight studies. Six studies reported perceived discrimination/stigmatization in the disaster survivors. The most critical behavioral change was an increase in suicides compared with residents in the whole of Japan or affected by the earthquake and tsunami, but not by the nuclear disaster. Increased rate of alcohol and tobacco use was reported, although the effect on one's health was inconsistent. As a conclusion, the Fukushima nuclear disaster survivors suffered issues in risk perception, well-being, stigmatization, and alcohol/tobacco use in the first 8 years after the disaster. The present study is important in order to better understand the emotional and behavioral responses to future nuclear/radiological disasters as well as other "invisible" disasters, such as chemical and biological public health crises.

When, How, & Where Tobacco Initiation and Relapse Occur During U.S. Air Force Technical Training.

Military personnel are at high risk for tobacco use, particularly during the first year of military service. Technical Training follows an 8½week tobacco ban during basic military training and is a vulnerable time for personnel to both reinitiate and initiate tobacco use. Thus, this can be a crucial time to promote tobacco policies and interventions. However, there is limited research examining when, how, and where personnel access tobacco during the first year of service, particularly among users of newer products (eg, electronic cigarettes[e-cigarettes]). Thus, the purpose of the current study is to explore the timing, source, and location of tobacco use during Technical Training across all types of products. Furthermore, this study will examine differences in demographic characteristics and prior tobacco history in relationship to these tobacco behaviors. Participants were U.S. Air Force recruits completing Technical Training (2017-2018). Protocol was approved by the Institutional Review Board at the 59th Medical Wing of the U.S. Air Force. During the first week of Technical Training, Airmen were consented to participate in the study and completed a questionnaire about demographics and tobacco use history. Next, Airmen were randomized to receive one of three tobacco prevention interventions as part of military training. At a 3-month follow-up, during the last week of Technical Training, consented participants completed a questionnaire about current tobacco use. Airmen reported when (ie, first month vs. after), how (ie, "bummed" from another airman, bought on or off base, received from the internet or event), and where (ie, designated smoking areas on base, off base, bar or club, friend's house, cigar lounge, hookah bar, or vape shop) they used tobacco during Technical Training. Descriptive statistics were used to examine these behaviors across all tobacco products. Additionally, Wilcoxon-Mann-Whitney and Kruskal-Wallis tests compared differences in demographic characteristics and baseline tobacco use in relationship to these tobacco behaviors. No significant differences were found when comparing prior users and first-time users in relationship to tobacco behaviors during Technical Training; however, significant differences in educational background and age were found in regard to the source and location of tobacco use. Additionally, how and where Airmen first used tobacco during Technical Training differed across products. Cigarettes and smokeless tobacco were equally likely to be bought on or off base and most commonly first used at a designated smoking area on base. However, e-cigarettes, cigarillos/little cigars, and hookah were more likely to be bought off base, and first used at a specialty store (ie, vape shop, hookah bar, or cigar lounge). Tobacco use behaviors during Technical Training differed depending on the type of product. Specifically, new and emerging products were more likely to be bought off base and first used at a specialty store. Thus, military polices regulating on base tobacco pricing might not reduce the growing prevalence of e-cigarettes. Future policies might consider addressing the density of off-base tobacco retailers to reduce the high rates of tobacco use in this population.

Abstract TP252: Extended Window TPA is Safe at Community Emergency Departments via Telestroke

Introduction: Recent studies support tPA for acute ischemic stroke (AIS) patients presenting beyond 4.5 hours from last known well (LKW), if established infarct is not evident on advanced imaging. Many community hospitals, where AIS patients may be managed via telestroke (TS), lack advanced imaging capability and hesitate to administer off-label tPA. In our TS network, physicians adhere to an extended window tPA (EW) protocol also used in the hub emergency room; eligibility includes NIHSS≤25, &lt;1/3 MCA territory hypodensity on CT brain, and off-label tPA consent. Here, we characterize patients receiving EW via TS and investigate safety. Methods: We identified 1,150 AIS patients who received tPA via TS (9/2015-12/2018). We compared baseline characteristics between patients who received EW (arrival &gt;4.5 hrs) and those who received standard window tPA (SW, arrival ≤4.5 hrs). We explored clinical outcomes and describe incidence of adverse effects from tPA. Results: Forty patients received EW, with median ASPECTS of 9 (Q1-Q3: 9-10). Median LKW to arrival time was 491 mins with EW and 66 mins with SW (p&lt;0.0001, Table 1). EW led to few tPA complications; symptomatic intracranial hemorrhage incidence was 2%. EW was given for more severe stroke than SW (median NIHSS 10 vs 7, p=0.011). Both groups had comparable baseline characteristics, except a higher rate of tobacco use with EW. EW patients had longer length of stay (median 5 vs 3, p=0.023) and were more likely to be discharged to rehab than home (OR: 2.05 (1.01 4.15), p=0.046), however a small number of EW patients precludes in-depth comparative outcomes analysis. Conclusions: Our data suggest that EW is safe via TS for select patients with favorable CT, in settings that may lack advanced imaging capability. A specified mismatch between NIHSS and acute ischemia on plain CT is not part of our EW protocol, however EW is more likely given for severe stroke in our TS network. Small sample size warrants further study on clinical outcomes.
