RESUMO
Importance: Epistaxis is the greatest cause of morbidity in patients with hereditary hemorrhagic telangiectasia (HHT); because of this, a validated epistaxis-specific quality-of-life instrument for HHT should be made available. Objective: To develop and validate an epistaxis-specific quality-of-life patient-reported outcome measure for HHT. Design, Setting, and Participants: This survey study focused on the development and validation of the Nasal Outcome Score for Epistaxis (NOSE) in HTT (NOSE HHT) outcome measure with data prospectively collected from December 10, 2019, to March 15, 2020. A total of 401 patients were recruited from within the Cure Hemorrhagic Telangiectasia online patient advocacy social media network, the Washington University HHT Center of Excellence, and a randomized clinical trial investigating an intranasal timolol gel for HHT-associated epistaxis. Main Outcomes and Measures: Face and content validity, factor analysis, internal consistency as measured through Cronbach α, construct validity, responsiveness to change, and minimal clinically important difference. Results: The NOSE HHT was developed and validated with a possible score ranging discretely from 0 to 4 for each of the 29 items and a total score ranging continuously from 0 to 4 after dividing by the total number of items answered. A total of 401 participants completed the NOSE HHT. Factor analysis identified 3 factors that matched the a priori specified subgroups of particular aspects of life affected by HHT-associated epistaxis: physical problems (mean [SD] magnitude, 1.59 [0.83]), functional limitations (mean [SD] magnitude, 1.28 [0.84]), and emotional consequences (mean [SD] magnitude, 1.95 [1.02]). The instrument had high internal consistency with an overall Cronbach α of 0.960. Convergent validity determined the total NOSE HHT score to be a strong predictor of disease severity; total NOSE HHT score can be split up into the following epistaxis severity categories: mild (0-1), moderate (1.01-2), and severe (>2). The instrument was found to be sensitive to change, and the minimal clinically important difference for the total NOSE HHT score was 0.46. Conclusions and Relevance: Evaluation of the consistency, reliability, and responsiveness of the NOSE HHT survey found it to be a valid instrument to assess severity and change in epistaxis. Study results suggest that the NOSE HHT survey is clinically applicable and useful as an outcome measure of future HHT-associated epistaxis trials.

BACKGROUND: This study was designed to identify factors associated with clinical response to extracorporeal photopheresis (ECP) and mortality after ECP in lung allograft recipients with bronchiolitis obliterans. METHODS: Forced expiratory volume in 1 second (FEV1) values obtained 6 months before (baseline) and 6 months after initiation of ECP were used to plot the linear relationship between FEV1 versus time before and after ECP. Response to ECP was assigned when a positive integer was derived after subtracting the baseline rate of decline from the rate of decline 6 months after ECP. Univariate and multivariate logistic regression analyses were used to identify demographic, treatment-related factors or spirometric parameters that may be associated with response to ECP or mortality at either 6 or 16 months after initiation of ECP. RESULTS: Forced expiratory volume in 1 second just before ECP was associated with mortality (P = 0.007) at 16 months after ECP initiation. An FEV1 of 1.50 L or less had a sensitivity of 87% and specificity of 60% to identify patients who died within 16 months after ECP initiation. Patients whose FEV1 decline exceeded 40 mL/month were 12 times more likely to have a response to ECP (P = 0.0001). Patients whose decline in FEV1 before ECP was statistically significant (P < 0.05) were nearly 10 times (P = 0.008) more likely to respond to ECP. CONCLUSIONS: Forced expiratory volume in 1 second is an important predictor of mortality, and the response to ECP is influenced by both the extent (>40 mL/mo) and statistical significance of the relationship between FEV1 versus time before ECP initiation. Therefore, earlier bronchiolitis obliterans detection and more timely implementation of ECP (ie, when FEV1 values >1.5 L) should be considered especially in patients with a more aggressive rate of decline of lung function.

BACKGROUND: The most common instruments used for extracorporeal photopheresis (ECP) treatment in the United States are the UVAR XTS and the CELLEX devices (Therakos, West Chester, PA). When compared to the UVAR XTS instrument, the efficacy of the CELLEX instrument to arrest the decline in lung function in patients with chronic lung allograft dysfunction (CLAD) related to bronchiolitis obliterans (BOS) has not been previously evaluated. METHODS: The relative efficacy of the CELLEX vs UVAR XTS ECP instruments was assessed by comparing the difference in rates of FEV1 decline before and after ECP treatment and survival in two series of lung allograft recipients with BOS who had been treated with these instruments. RESULTS: Similar Slope Difference values for change in rate of decline (6 months Post ECP - Pre ECP) were observed between the two cohorts (UVAR XTS: 85 ± 109 mL/month vs CELLEX: 76 ± 128 mL/month, p=0.72). A similar percentage of patients responded to ECP (UVAR XTS: 77% vs CELLEX: 89%; p=0.36) i.e., as defined as a positive difference in slope between the rate of decline of FEV1 before and 6 months after ECP. Survival at either 6 (p=0.89) or 12 (p=0.8) months after the start of ECP was not associated with instrument used despite a trend in higher early mortality (34% vs 17%, p=0.054) in the patients who were predominately treated with the CELLEX. CONCLUSIONS: Our data support the use of the CELLEX for prospective studies designed to evaluate the merits of ECP in this population.

INTRODUCTION: With more states legalizing marijuana use, the marijuana industry has grown, introducing a variety of marijuana products. Our study explores the use of multiple marijuana products (poly-marijuana use) and the characteristics associated with this behavior. METHODS: Past-month marijuana users aged 18-34years were surveyed online via an existing online panel (n=2444). Participants answered questions about past-month use of three types of marijuana (plant-based, concentrates, edibles), marijuana use patterns, and driving after use. Latent class analysis was used to identify subgroups of marijuana users. RESULTS: Four classes of marijuana users were identified: Light plant users, who used only plant-based products infrequently and were unlikely to drive after use (32%); Heavy plant users, who used mainly plant-based products frequently, multiple times per day, and were likely to drive after use (37%); Plant and concentrates users, who used plant-based products heavily and concentrates at least infrequently, used multiple times per day, and were likely to drive after use (20%); Light plant and edibles users, who used both products infrequently and were unlikely to drive after use (10%). Those in legal marijuana states were more likely to belong to the poly-marijuana groups. DISCUSSION: Our findings reflect the increase in popularity of new marijuana products in legal states and suggest that heavy user groups, including concentrates users, are associated with driving after use. As various forms of marijuana use increases, monitoring and surveillance of the use of multiple types of marijuana will be important for determining potential varying impacts on physiological and social consequences.

BACKGROUND: Little is known about marijuana advertising exposure among users in the U.S. We examined the prevalence of advertising exposure among young adult marijuana users through traditional and new media, and identified characteristics associated with seeking advertisements. METHODS: We conducted a cross-sectional survey of 18-34 year-old past-month marijuana users in the U.S. using a pre-existing online panel (N=742). The survey queried about passively viewing and actively seeking marijuana advertisements in the past month, sources of advertisements, and marijuana use characteristics. RESULTS: Over half of participants were exposed to marijuana advertising in the past month (28% passively observed advertisements, 26% actively sought advertisements). Common sources for observing advertisements were digital media (i.e., social media, online, text/emails; 77%). Similarly, those actively seeking advertisements often used Internet search engines (65%) and social media (53%). Seeking advertisements was more common among those who used medically (41% medical only, 36% medical and recreational) than recreational users (18%), who used concentrates or edibles (44% and 43%) compared to those who did not (20% and 19%), and who used multiple times per day (33%) compared to those who did not (19%) (all p<0.01). CONCLUSIONS: Exposure to marijuana advertising among users is common, especially via digital media, and is associated with medical use, heavier use, and use of novel products with higher THC concentrations (i.e., concentrates) or longer intoxication duration (i.e., edibles). As the U.S. marijuana policy landscape changes, it will be important to examine potential causal associations between advertising exposure and continuation or frequency/quantity of use.

Importance: Individuals with tinnitus have poorer working memory, slower processing speeds and reaction times, and deficiencies in selective attention, all of which interfere with readiness and performance. Brain Fitness Program-Tinnitus (BFP-T) is a cognitive training program specially designed to exploit neuroplasticity for preservation and expansion of cognitive health in adults with tinnitus. Objective: To evaluate the effect of the BFP-T on tinnitus. Design, Setting, and Participants: This open-label, intention-to-treat randomized clinical trial prescreened 191 patients with tinnitus and 64 healthy controls (HCs) from June 1, 2012, through October 31, 2013. Participants were 40 adults with bothersome tinnitus for more than 6 months and 20 age-matched HCs. Patients with tinnitus were randomized to a BFP-T or non-BFP-T control group. The BFP-T was completed online, and assessments were completed at Washington University School of Medicine. Interventions: Participants in the intervention group were required to complete the BFP-T online 1 hour per day 5 days per week for 8 weeks. Tinnitus assessment, neuroimaging, and cognitive testing were completed at baseline and 8 weeks later. The HCs underwent neuroimaging and cognitive assessments. Main Outcomes and Measures: The primary outcome measure was the change in Tinnitus Handicap Inventory (THI) score. Behavioral measures, neuroimaging, and cognitive tests were performed before and after the intervention. Results: A total of 40 patients with tinnitus and 20 HCs participated in the study (median [range] age, 56 [35-64] years in the BFP-T group, 52 [24-64] years in the non-BFP-T group, and 50 [30-64] years in the HC group; 13 [65%] in the BFP-T group, 14 [70%] in the non-BFP-T group, and 13 [65%] in the HC group were males; and 16 [80%] in the BFP-T group, 16 [80%] in the non-BFP-T group, and 15 [75%] in the HC group were white). There was a reduction in the THI score in the BFP-T group (median, 7; range, -16 to 64) and non-BFP-T group (median, 11; range, -6 to 26), but this reduction was not significantly different between the 2 groups (median difference, 0; 95% CI, -10 to 8). There was no difference in cognitive test scores and other behavioral measures. There was a significant difference between baseline and follow-up in functional connectivity in cognitive control regions in the BFP-T group but not in HCs or individuals with untreated tinnitus. Of the 20 patients in the BFP-T group, 10 (50%) self-reported improvement attributable to the intervention, and 6 (30%) reported to be much improved in the domains of tinnitus, memory, attention, and concentration. Conclusions and Relevance: These findings suggest that the computer-based cognitive training program is associated with self-reported changes in attention, memory, and perception of tinnitus. A possible mechanistic explanation for these changes could be neuroplastic changes in key brain systems involved in cognitive control. Cognitive training programs might have a role in the future treatment of patients with tinnitus. Trial Registration: clinicaltrials.gov Identifier: NCT01458821.

BACKGROUND: Optimal stimulus parameters for electroconvulsive therapy (ECT) are unclear. Pulse duration and frequency related to convulsive threshold and seizure duration in the first ECT treatment in a series were evaluated. METHODS: Convulsive threshold was estimated for all patients (N = 550) receiving ECT over 27 months. Thresholds were estimated using different brief pulse stimulators, starting with a dose of approximately 25 mC per pulse train for right unilateral (RUL) stimulation (50 mC for bilateral [BL] stimulation). The charge was applied in 25-mC serial increments (approximately doubling for BL stimulation) up to approximately 100 mC (>200 mC for BL stimulation) to a generalized motor seizure endpoint. Patients lacking seizure response at 100 mC (200 mC for BL stimulation) received >500 mC. RESULTS: Convulsive threshold increased with age, African American identity, diagnosis other than depression, and female sex, and decreased with RUL electrode placement, low frequency (30 Hz), and brief pulse width (0.5 msec). RUL stimulation and lower anesthetic medication doses promoted longer seizures. Younger patients had longer seizures than older patients. Pulse width and frequency did not affect seizure duration. Lower charge yielded longer seizures. CONCLUSIONS: ECT efficiency appears to be achieved by lower frequency and briefer pulse duration stimulation. Randomized trials are needed for corroboration of these findings.

BACKGROUND: Effective policies that can reduce alcohol use behaviors and impaired driving among young people at a population level are needed. Graduated driver licensing (GDL) laws increase the driving privileges of young novice drivers as they age and gain more driving experience. In this study, we seek to determine the effects of GDLs on risky driving behaviors of youth and to assess if GDLs have an unintended effect on underage drinking behaviors. METHODS: We utilized 2000 to 2013 data on 12th grade students from the Monitoring the Future (MTF) study, an ongoing, annual national survey (since 1975) that studies the substance use behaviors of adolescents, as well as data on GDL laws obtained via the Insurance Institute for Highway Safety (IIHS). We conducted a series of regular logistic regression models that included fixed effects for year and state, and adjusted for demographic characteristics, school characteristics, and other state alcohol policies. RESULTS: Total weighted sample size was 129,289 12th graders. Past month alcohol use and binge drinking (i.e., ≥5 drinks on one occasion) in the past 2 weeks were 45 and 26%, respectively. Seventeen percent of respondents reported riding with a driver who drank alcohol. Nearly 12% reported driving in the past 2 weeks after drinking alcohol, and 7% reported driving after binge drinking. Over half of the students lived in a state with a "good" GDL law. The logistic regression models suggest a link between restrictive GDL policies and a reduction of alcohol use behaviors and risky driving behaviors among youth. CONCLUSIONS: Our findings indicate that the effects of GDLs extend beyond driving-related risks and into other drinking-related behaviors that pose immediate or delayed health risks for young people. We speculate that GDLs may dictate social norms and expectations for youth risk behaviors, and should be maximized throughout the United States.

OBJECTIVE: Multiple levels of influence interplay to impact youth tobacco use. We work towards understanding important policy and environmental strategies that are associated with youth tobacco use behaviors. METHODS: We utilized data from participants of the Monitoring the Future (MTF) study and linked national data from multiple sources to assess correlates of youth tobacco use behaviors across individual, family, school, community, and state-level policy influences. RESULTS: Higher cigarette prices had the strongest association with youth tobacco use behaviors. Demographic and socio-economic characteristics at the individual, familial, and community/school-levels were associated with youth tobacco use behaviors. CONCLUSIONS: In the present study, we confirm that higher cigarette prices could help to reduce youth tobacco use behaviors. Several states are still lagging behind in terms of their low cigarette tax and they should enact tax policies to reduce youth tobacco use.
RESUMO
OBJECTIVE: To explore the feasibility of ecological momentary assessments (EMAs) as a tool to more accurately assess the level of bother from tinnitus. STUDY DESIGN: Longitudinal observational study. SETTING: Washington University Department of Otolaryngology-Head and Neck Surgery faculty practice plan. SUBJECTS AND METHODS: Twenty participants with moderately to severely bothersome tinnitus were enrolled. All participants owned a smartphone device, and all communications were conducted via email, phone, and text messaging. Participants received 4 EMAs per day for 2 weeks via text message and a final survey on the 15th day. In each survey, participants recorded their level of tinnitus bother, their location at the time of response, their stress level, how they were feeling, and what they were doing. Response rates as a proxy for the feasibility of the program. RESULTS: There were a total of 1120 surveys sent to 20 participants (56 surveys per participant), and 889 (79.4%) of the surveys were completed and returned. The median time to response from the moment of receiving the text message was 7 minutes. The distribution of responses to the EMA question, "In the last 5 minutes, how bothered have you been by your tinnitus?" displayed both high between- and within-subject variability. At the end of 2 weeks, the median score on the Tinnitus Handicap Inventory was 37, with a range of 10 to 82 points; the median Tinnitus Functional Index score was 43, with a range of 10 to 82 points. CONCLUSION: This study suggests bothered tinnitus patients will use smartphones as part of EMA.

The National Comprehensive Cancer Network (NCCN) describes the presence of extracapsular spread and/or positive margins in oropharynx cancer (OPC) as an indication for the addition of chemotherapy to postoperative radiation. The guideline's category 1 consensus is based on what they term high-level evidence. For this study, the authors performed a critical appraisal of the research upon which the NCCN guideline is based and assessed its relevance in the era of human papillomavirus (HPV)/p16-positive OPC. Multiple shortcomings were identified, including patient exclusion after randomization and the use of unplanned subgroup analyses without multivariate adjustment, which undermined internal validity. Indeterminate HPV/p16 status limited external validity. Given the unique biology of HPV/p16-positive tumors and the problems of internal and external validity, the authors concluded that the literature upon which the recommendation for the addition of chemotherapy to adjuvant radiation was based does not generate high-level evidence, and its relevance for the postoperative management of patients with HPV/p16-positive OPC remains unknown.

We utilized an updated nationally representative database to examine associations between maternal age and prevalence of maternal morbidity during complications of labor and delivery. We used hospital inpatient billing data from the 2009 United States Nationwide Inpatient Sample, part of the Healthcare Cost and Utilization Project. To determine whether the likelihood that maternal morbidity during complications of labor and delivery differed among age groups, separate logistic regression models were run for each complication. Age was the main independent variable of interest. In analyses that controlled for demographics and clinical confounders, we found that complications with the highest odds among women, 11-18 years of age, compared to 25-29 year old women, included preterm delivery, chorioamnionitis, endometritis, and mild preeclampsia. Pregnant women who were 15-19 years old had greater odds for severe preeclampsia, eclampsia, postpartum hemorrhage, poor fetal growth, and fetal distress. Pregnant women who were ≥35 years old had greater odds for preterm delivery, hypertension, superimposed preeclampsia, severe preeclampsia, and decreased risk for chorioamnionitis. Older women (≥40 years old) had increased odds for mild preeclampsia, fetal distress, and poor fetal growth. Our findings underscore the need for pregnant women to be aware of the risks associated with extremes of age so that they can watch for signs and symptoms of such complications.

BACKGROUND: Google Trends is an innovative monitoring system with unique potential to monitor and predict important phenomena that may be occurring at a population level. We sought to validate whether Google Trends can additionally detect regional trends in youth and adult tobacco use. METHODS: We compared 2011 Google Trends relative search volume data for cigars, cigarillos, little cigars and smokeless tobacco with state prevalence of youth (grades 9-12) and adult (age 18 and older) use of these products using data from the 2011 United States state-level Youth Risk Behaviors Surveillance System and the 2010-2011 United States National Survey on Drug Use and Health (NSDUH), respectively. We used the Pearson correlation coefficient to measure the associations. RESULTS: We found significant positive correlations between state Google Trends cigar relative search volume and prevalence of cigar use among youth (r=0.39, R(2) = 0.154, p=0.018) and adults (r=0.49, R(2) = 0.243, p<0.001). Similarly, we found that the correlations between state Google Trends smokeless tobacco relative search volume and prevalence of smokeless tobacco use among youth and adults were both positive and significant (r=0.46, R(2) = 0.209, p=0.003 and r=0.48, R(2) = 0.226, p<0.001, respectively). CONCLUSIONS: The results of this study validate that Google Trends has the potential to be a valuable monitoring tool for tobacco use. The near real-time monitoring features of Google Trends may complement traditional surveillance methods and lead to faster and more convenient monitoring of emerging trends in tobacco use.

OBJECTIVE: The study examined factors in the risk trajectory for Substance Use Disorder (SUD) over a 10-12 year period in children with ADHD. METHOD: N=145 children between the ages of 7 and 16 with ADHD and healthy controls were assessed every 2 years for 10-12 years as part of a larger, longitudinal investigation. Onset of substance use disorder was examined using Cox proportional hazards modeling, and included child and parent psychopathology, and parental warmth as well as other key factors. RESULTS: Low paternal warmth and maternal SUD were predictors of SUD in n=59 ADHD participants after adjusting for gender, child ODD, paternal SUD, maternal/paternal ADHD, maternal/paternal major depressive disorder (MDD), maternal/paternal anxiety, and low maternal warmth in the Cox model. CONCLUSIONS: Longitudinal study findings suggest that in addition to the established risk of ADHD and maternal SUD in development of child SUD, low paternal warmth is also associated with onset of SUD. This was evident after controlling for pertinent parent and child psychopathology. These findings suggest that paternal warmth warrants further investigation as a key target for novel interventions to prevent SUD in children with ADHD. More focused investigations examining paternal parenting factors in addition to parent and child psychopathology in the risk trajectory from ADHD to SUD are now warranted.
RESUMO
BACKGROUND: Multiple valid comorbidity indices exist to quantify the presence and role of comorbidities in cancer patient survival. Our goal was to compare chart-based Adult Comorbidity Evaluation-27 index (ACE-27) and claims-based Charlson Comorbidity Index (CCI) methods of identifying comorbid ailments and their prognostic abilities. STUDY DESIGN: We conducted a prospective cohort study of 6,138 newly diagnosed cancer patients at 12 different institutions. Participating registrars were trained to collect comorbidities from the abstracted chart using the ACE-27 method. The ACE-27 assessment was compared with comorbidities captured through hospital discharge face sheets using ICD coding. The prognostic accomplishments of each comorbidity method were examined using follow-up data assessed at 24 months after data abstraction. RESULTS: Distribution of the ACE-27 scores was: "none" for 1,453 (24%) of the patients; "mild" for 2,388 (39%); "moderate" for 1,344 (22%), and "severe" for 950 (15%) of the patients. Deyo's adaption of the CCI identified 4,265 (69%) patients with a CCI score of 0, and the remaining 31% had CCI scores of 1 (n = 1,341 [22%]), 2 (n = 365 [6%]), or 3 or more (n = 167 [3%]). Of the 4,265 patients with a CCI score of zero, 394 (9%) were coded with severe comorbidities based on ACE-27 method. A higher comorbidity score was significantly associated with higher risk of death for both comorbidity indices. The multivariable Cox model, including both comorbidity indices, had the best performance (Nagelkerke's R(2) = 0.37) and the best discrimination (C index = 0.827). CONCLUSIONS: The number, type, and overall severity of comorbid ailments identified by chart- and claims-based approaches in newly diagnosed cancer patients were notably different. Both indices were prognostically significant and able to provide unique prognostic information.

AIMS: To examine the associations between youth poly-tobacco use and substance use disorders. DESIGN: Analysis of data from the 2007-11 US National Survey on Drug Use and Health. SETTING: Randomly selected, household-dwelling adolescents from the non-institutionalized, civilian population of the United States. PARTICIPANTS: A total of 91 152 adolescents (aged 12-17 years). METHODS: Logistic regression models were used to examine the associations between type of tobacco user (non-user, users of alternative tobacco products only, users of cigarettes only and users of cigarettes plus alternative tobacco products) with past year alcohol, marijuana or other illicit drug use disorders, adjusting for demographic and social variables. FINDINGS: Compared with non-users of tobacco, the greatest risk for substance use disorders was among users of cigarettes plus alternative tobacco products [alcohol disorder adjusted odds ratio (aOR) = 18.3, 95% confidence interval (CI) = 16.2-20.6; marijuana disorder aOR = 37.2, 95% CI = 32.5-42.7; other drug disorder aOR = 18.4, 95% CI = 15.4-21.8], followed by users of cigarettes only (alcohol disorder aOR = 9.6, 95% CI = 8.8-10.6; marijuana disorder aOR = 20.4, 95% CI = 18.1-23.0; other drug disorder aOR = 9.4, 95% CI = 7.8-11.4), then users of alternative tobacco products only (alcohol disorder aOR = 8.1, 95% CI = 6.7-9.6; marijuana disorder aOR = 9.2, 95% CI = 7.5-11.4; other drug disorder aOR = 3.2, 95% CI = 2.4-4.3). CONCLUSIONS: Tobacco use in adolescence is associated with higher rates of substance use disorders across all tobacco users, especially among those who use cigarettes plus other tobacco products.

BACKGROUND: Raising cigarette prices through taxation is an important policy approach to reduce smoking. Yet, cigarette price increases may not be equally effective in all subpopulations of smokers. PURPOSE: To examine differing effects of state cigarette price changes with individual changes in smoking among smokers of different intensity levels. METHODS: Data were derived from the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample of US adults originally interviewed in 2001-2002 (Wave 1) and re-interviewed in 2004-2005 (Wave 2): 34 653 were re-interviewed in Wave 2, and 7068 smokers defined at Wave 1 were included in our study. Mixed effects linear regression models were used to assess whether the effects of changes in state cigarette prices on changes in daily smoking behaviour differed by level of daily smoking. RESULTS: In the multivariable model, there was a significant interaction between change in price per pack of cigarettes from Wave 1 to Wave 2 and the number of cigarettes smoked per day (p=0.044). The more cigarettes smoked per day at baseline, the more responsive the smokers were to increases in price per pack of cigarettes (ie, number of cigarettes smoked per day was reduced in response to price increases). CONCLUSIONS: Our findings that heavier smokers successfully and substantially reduced their cigarette smoking behaviours in response to state cigarette price increases provide fresh insight to the evidence on the effectiveness of higher cigarette prices in reducing smoking.
