Research is limited on the effects of regular substance use on mental health-related outcomes. We used a large nationally representative survey to examine current and future quality of life and risk of psychiatric disorders among past-year regular (weekly) users of alcohol, nicotine, and cannabis. Data on psychiatric disorders and quality of life from two waves (Wave 1 N = 43,093, Wave 2 N = 34,653) of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC) were used to test study aims. In cross-sectional analyses, regular nicotine and cannabis use were associated with higher rates of psychiatric disorder, though regular alcohol use was associated with lower rates of disorders. Prospective analyses found that regular nicotine use predicted onset of anxiety, depressive, and bipolar disorders. Regular alcohol use predicted lower risk of these disorders. Regular cannabis use uniquely predicted the development of bipolar disorder, panic disorder with agoraphobia, and social phobia. Lastly, regular alcohol use predicted improvements in physical and mental health-related quality of life, whereas nicotine predicted deterioration in these outcomes. Regular cannabis use predicted declines in mental, but not physical health. These data add to the literature on the relations between substance use and mental and physical health and suggest increased risk of mental health problems among regular nicotine and cannabis users and better mental and physical health among regular alcohol users. Examination of mechanisms underlying these relationships is needed. [ABSTRACT FROM AUTHOR]

Objective: To perform a systematic review of the utility of exoskeleton robotic therapy on lower extremity recovery in Spinal Cord Injury (SCI) patients., Methods: We used the Embase, Cochrane, and PubMed databases and searched from January 2012 to December 2023 for studies on exoskeleton robotic assist devices used in working with SCI patients. Only articles published in English were evaluated, and the retrieved articles were screened via our inclusion/exclusion criteria. We conducted our meta-analysis with the Cochrane Review Manager 5.4 (RevMan) software. Robotic assisted gait training and conventional gait training methodology were compared using Walking Index for Spinal Cord Injury II (WISCII), Spinal Cord Independence Measure III (SCIM III), and 6 Minute Walk Test (6MWT) as reported outcome measures., Results: Eleven randomized clinical trials (RCTs) involving 552 total participants were included in the meta-analysis. The results of the meta-analysis indicated statistically significant improvement in SCIM III [MD 5.14, 95 % CI = (4.47, 5.810), P < 0.00001], WISCII [MD 2.31, 95 % CI = (2.13, 2.49), P < 0.00001] and 6MWT [MD 37.04, 95 % CI = (32.35, 41.74), P < 0.00001] in patients with SCI as compared to conventional gait training (CGT) therapy. Conclusion : Robotic Therapy could improve ambulation/quality of life in patients with spinal cord injuries compared to the standard treatment only, but future studies should include additional measures addressing quality of life and patient satisfaction., Competing Interests: None., (© 2024 Professor P K Surendran Memorial Education Foundation.

Background: The anatomic substrate of bicuspid valves may lead to suboptimal TAVR stent expansion and geometry., Aim: We evaluated determinants of stent geometry in bicuspid valves treated with Sapien transcatheter aortic valve replacement (TAVR) valves., Methods: A multicenter retrospective registry of patients (February 2019 to August 2022) who underwent post-TAVR computed tomography to determine stent area (vs. nominal valve area) and stent ellipticity (maximum diameter/minimum diameter). Predictors of relative stent expansion (minimum area/average of inflow + outflow area) and stent ellipticity were evaluated in a multivariable regression model, including valve calcium volume (indexed by annular area), presence of raphe calcium, sinus diameters indexed by area-derived annular diameter, and performance of pre-dilation and post-dilation., Results: The registry enrolled 101 patients from four centers. The minimum stent area (vs. nominal area) was 88.1%, and the maximum ellipticity was 1.10, with both observed near the midframe of the valve in all cases. Relative stent expansion ≥90% was observed in 64/101 patients. The only significant predictor of relative stent expansion ≥90% was the performance of post-dilation (OR: 4.79, p = 0.018). Relative stent expansion ≥90% was seen in 86% of patients with post-dilation compared to 57% without (p < 0.001). The stent ellipticity ≥1.1 was observed in 47/101 patients. The significant predictors of stent ellipticity ≥1.1 were the indexed maximum sinus diameter (OR: 0.582, p = 0.021) and indexed intercommisural diameter at 4 mm (OR: 2.42, p = 0.001). Stent expansion has a weak negative correlation with post-TAVR mean gradient (r = -0.324, p < 0.001)., Conclusion: Relative stent expansion ≥90% was associated with the performance of post-dilation, and stent ellipticity ≥1.1 was associated with indexed intercommisural diameter and indexed maximum sinus diameter. Further studies to determine optimal deployment strategies in bicuspid valves are needed., (© 2024 The Author(s).

With an estimated prevalence of 68% among healthy adults without a previous diagnosis of scoliosis, adult spinal deformities are a growing concern as the population ages. Our understanding of this growing concern has been historically guided by previous studies performed on the pediatric population. Over time, different classifications have been developed with their own respective limitations. The Roussouly classification was the first classification to describe the shapes of an asymptomatic spine. It considers lumbar lordosis, pelvic incidence, and the inflection point from lumbar lordosis to thoracic kyphosis to attempt to stratify the shapes of an asymptomatic spine. This classification aims to guide treatment, provide information regarding prognosis, allow stratification for research, and be highly reproducible. Overall, the Roussouly classification is a novel way to think about sagittal malalignment, considering the patient's individual anatomy, while allowing for communication between surgeons. Additionally, it has proven to be a reliable system that provides prognostic value for clinicians and may minimize complications when a patient's sagittal alignment is optimized using this classification system., Competing Interests: The authors report no funding.

Objective: Suicide is the second leading cause of death in Canadian adolescents. The Interpersonal Theory of Suicide attempts to explain suicide etiology and proposes that feelings of perceived burdensomeness or thwarted belongingness lead to suicide ideation, but this has not been extensively studied in adolescents. This study aimed to use the Interpersonal Theory of Suicide to examine factors that may be associated with suicide ideation in adolescents. The factors of interest were school connectedness, perceived availability of support, self-esteem, feelings of worthlessness, feelings of hopelessness, bullying and cyberbullying victimization, substance use, and social media use., Methods: Data were from the 2017 Ontario Student Drug Use and Health Survey, a survey of 7th to 12th graders enrolled in a publicly funded school in Ontario. Weighted multivariate logistic regression of suicide ideation on all exposure variables was conducted., Results: 13.6% of students in the sample endorsed having suicidal ideation in the preceding 12 months. Not knowing where to turn to for support, feeling worthless, endorsing low self-esteem, being bullied, and using cannabis were each associated with greater odds of suicide ideation. Feeling hopeless, social media use, using alcohol and tobacco , and being cyberbullied were not associated with suicide ideation in the weighted multivariate logistic regression model., Conclusions: This study is consistent with the Interpersonal Theory of Suicide as low self-esteem and feelings of worthlessness, two indicators of perceived burdensomeness, and not knowing where to turn to for support, an indicator of thwarted belongingness, were associated with greater odds of suicide ideation. These findings can help guide interventions aimed at reducing the burden of suicidality during adolescence and demonstrate the need to provide accessible mental health support for youth.

Objective: Cefazolin is a heat-labile antibiotic that is not usually added to polymethylmethacrylate (PMMA) cement spacers because it is believed to be inactivated by the high polymerization temperatures. The purpose of this study was to compare cefazolin versus vancomycin high-dose antibiotic cement spacers., Methods: High-dose antibiotic PMMA spacers with either cefazolin or vancomycin were fabricated. Setting time, compressive strength, and compression modulus of spacers were measured. Spacers were emerged in saline, and the eluent was tested on days 1, 2, 3, 7, 14, and 30 to determine the zone of inhibition of methicillin-sensitive Staphylococcus aureus and estimate the cumulative antibiotic released., Results: Cefazolin, compared with vancomycin-loaded spacers, had significantly shorter setting time [mean difference (MD) -1.8 minutes, 95% confidence interval (CI), -0.6 to -3.0], greater compressive strength (MD 20.1 megapascal, CI, 15.8 to 24.5), and compression modulus (MD 0.15 megapascal, CI, 0.06 to 0.23). The zone of inhibition of eluent from PMMA-C spacers was significantly greater than PMMA-V spacers at all time points, an average of 11.7 ± 0.8 mm greater across time points. The estimated cumulative antibiotic released from cefazolin spacers was significantly greater at all time points ( P < 0.0001)., Conclusions: Cefazolin was not inactivated by PMMA polymerization and resulted in spacers with superior antimicrobial and biomechanical properties than those made with vancomycin, suggesting that cefazolin could play a role in the treatment of infected bone defects with high-dose antibiotic PMMA spacers., Competing Interests: The authors report no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Introduction: While nicotine replacement therapy (NRT) is a frontline tobacco treatment that doubles smoking quit rates, only about 18% of Black adults who smoke cigarettes report lifetime use of NRT. A promising approach for increasing NRT use is in-session (in-vivo) NRT sampling within cessation interventions. The present pilot study examined the effectiveness of an in-vivo NRT sampling intervention within a single-session, culturally-targeted motivational intervention trial in Black adults who smoke cigarettes., Methods: Non-treatment-seeking disadvantaged Black adults (N = 60) were offered the choice to sample nicotine lozenge, patch, or both in-session with the counselor present. Regardless of their choice, they were offered a one-week starter kit of both products. Data were analyzed at baseline and 1-month follow-up. Primary outcomes were 1) differences in motivation to quit smoking among NRT samplers versus non-samplers, 2) in-vivo NRT sampling preferences, and 3) in-vivo sampling's association with NRT use and improved smoking outcomes at follow up., Results: Almost all participants accepted a take-home NRT starter kit, and approximately half of those offered in-vivo sampling agreed to sample. Participants preferred sampling lozenges in session (75.8% lozenge only vs. 12.1% nicotine patch only or 12.1% both; p < .001). Motivation to quit smoking was not related to likelihood of in-vivo NRT sampling (p > .05). At 1-month follow-up, in-vivo samplers were more likely to use NRT (94% vs. 35%, respectively; p < .001) and report a quit attempt (81.8% vs. 53.9%, p < .05) compared to non-samplers., Conclusion: In-vivo NRT sampling is a promising strategy to improve NRT uptake among Black adults who smoke cigarettes, regardless of motivation to quit smoking., (Copyright © 2022 Elsevier B.V.

Background: Annular and left ventricular outflow tract (LVOT) calcification increase the risk of annular rupture following transcatheter aortic valve replacement (TAVR). The outcomes of a strategy of routine use of a balloon-expandable valve (BEV) for all patients irrespective of annular or LVOT calcium is unknown., Objectives: We evaluated the impact of bespoke sizing on annular rupture in patients treated with a BEV., Methods: All consecutive patients undergoing TAVR at a single centre (February 2020-February 2022) were treated only with a BEV. No other valve design was used. Annular/LVOT calcification was assessed using a standardized grading system. For each annular area, we determined the percentage valve oversizing with nominal deployment. The balloon deployment volume was then adjusted when required (over-/underfilled) to achieve over-sizing of approximately 5% in the presence of annular/LVOT calcium and 5%-10% in the absence of annular/LVOT calcium. Adjusted valve areas were assumed to change proportionately to the change in balloon deployment volume., Results: Among 533 TAVR treated patients, annular/LVOT calcification was present in 166 (31.1%) and moderate or severe in 90 (16.9%). In patients with annular/LVOT calcification, the adjusted oversizing was 3.5 ± 3.6% and in patients without annular/LVOT calcification, the adjusted oversizing was 6.8 ± 4.7% (p &lt; 0.001). There were no cases of annular rupture and no cases with more than mild paravalvular leak (PVL). Mild PVL was more frequent in patients with annular/LVOT calcium (10.8% vs 4.6%, p = 0.01)., Conclusion: Bespoke BEV sizing by adjustment of balloon deployment volume avoided annular rupture in patients undergoing TAVR., (© 2022 Wiley Periodicals LLC.)

Aims: The optimal strategy of monitoring for conduction disturbances in patients undergoing transcatheter aortic valve implantation (TAVI) is uncertain. We evaluated a pre- and post-TAVI remote ambulatory cardiac monitoring (rACM) strategy for identification of conduction disturbances and to reduce unplanned pre-discharge post-TAVI permanent pacemaker implantation (PPMI)., Methods and Results: REdireCT TAVI (NCT0381820) was a prospective cohort study of patients referred for outpatient TAVI. Patients with prior PPMI were excluded. Remote ambulatory cardiac monitoring consisted of 2 weeks of continuous electrocardiogram (ECG) monitoring (Pocket-ECGTM) both before and after TAVI. Compliance to monitoring, frequency of notifications, unplanned PPMI post-TAVI, and length of hospitalization were measured. Between June 2018 and March 2020, in 192 undergoing TAVI (mean age: 81.8 years; female sex 46%; balloon-expandable valve 95.3%), compliance to rACM was 91.7% pre-TAVI (mean duration: 12.8 days), and 87.5% post-TAVI (mean duration: 12.9 days). There were 24 (12.5%) rACM notifications (13 pre-TAVI; 11 post-TAVI) resulting in 14 (7.3%) planned PPMI: seven pre-TAVI [due to sinus pauses n = 2 or atrio-ventricular block (AVB) n = 5] and seven post-TAVI [due to sinus pauses n = 1 or AVB n = 5 or ventricular tachycardia (VT) n = 1]. In addition, nine (4.7%) patients received pre-TAVI PPMI due to high-risk baseline ECG (right bundle branch block with hemi-block or prolonged PR interval). Unplanned PPMI post-TAVI during index hospitalization occurred in six (3.1%) patients due to AVB and in one patient readmitted with AVB. The median length of stay post-TAVI was 1 day., Conclusion: A strategy of routine rACM was feasible and frequently led to PPMI. Our approach of 2-week rACM both pre- and post-TAVI achieves both high patient compliance and sufficient surveillance., Clinical Trial Registration: Clinical Trial Registration: https://clinicaltrials.gov/ct2/show/NCT03810820., Competing Interests: Conflict of interest: none declared., (© The Author(s) 2022.

Background/purpose: Acute subjective alcohol effects appear to play an important role in predicting alcohol hangover. However, no studies have used a laboratory-based alcohol challenge to examine the concurrent or longitudinal effects of subjective alcohol responses on hangover frequency. As such, we investigated the direct and indirect effects of alcohol stimulation, sedation, liking and wanting, as measured in a controlled setting, on hangover frequency over five years., Method: Participants were 294 young adult light-to-heavy social drinkers (aged 21-35 years, 42% female) enrolled in the Chicago Social Drinking Project. The study utilized a placebo-controlled, double blind, laboratory alcohol challenge and a battery of measures including the Biphasic Alcohol Effects Scale, Drug Effects Questionnaire, Hangover Symptom Scale, and alcohol use Quantity-Frequency Interview, with the latter two re-administered after five years., Results: Through the use of a path analysis, the present study found significant direct effects from alcohol liking to hangover frequency at initial testing. In addition, there were multiple significant indirect effects from greater alcohol liking and wanting to greater alcohol use quantity-frequency and, in turn, greater hangover frequency at initial testing and 5-year follow-up. Last, there were significant indirect effects from greater alcohol sedation to less alcohol use quantity-frequency and, in turn, less hangover frequency at initial testing and 5-year follow-up., Conclusion: This study highlights the role of the hedonic reward and motivational salience of alcohol as potential mechanisms of alcohol-related consequences (i.e., hangover) among light-to-heavy social drinking young adults., (Copyright © 2022 Elsevier Ltd.

Background: Optical coherence tomographic (OCT) imaging has enabled identification of lipid, with increasing interest in how it may affect coronary interventions and clinical outcomes. This review summarizes the available evidence around OCT identification of lipid and its effect on interventions, clinical events, and the natural history of coronary disease., Methods and results: We conducted a scoping review using the Medline, HealthStar, and Embase databases for articles published between 1996 and 2021. We screened 1,194 articles and identified 51 for inclusion in this study, summarizing the key findings. The literature supports a common OCT definition of lipid as low-signal regions with diffuse borders, validated against histology and other imaging modalities with acceptable intra- and inter-rater reliability. There is evidence that OCT-identified lipid at the site of stent implantation increases the risk of edge dissection, incomplete stent apposition, in-stent tissue protrusion, decreased coronary flow after stenting, side branch occlusion, and post-procedural cardiac biomarker increases. In mostly retrospective studies, lipid indices measured at non-stented sites are associated with plaque progression and the development of recurrent ischemic events., Conclusions: There is extensive literature supporting the ability of OCT to identify lipid and demonstrating a substantial impact of lipid on percutaneous coronary intervention outcomes. Future work to prospectively evaluate the effect of the characteristics of lipid-rich plaques on long-term clinical outcomes is needed.

Objective: This study investigated the rates of and change in past-year antidepressant use from 1999 to 2017 among a representative sample of Ontario adults and past-year alcohol users and problem drinkers. It examined whether alcohol use and problem drinking are associated with antidepressant use over time, whether gender moderated the effect of problem drinking on antidepressant use, and the potential correlates of past-year antidepressant use., Method: This study utilized data from the Centre for Addiction and Mental Health Monitor study, a repeat cross-sectional telephone survey of the Ontario general adult population. Data are from 15 annual cycles of the survey 1999-2017 (where relevant variables were included), resulting in a sample size of N = 35,210. Variables of interest included demographic variables, past-year antidepressant use, past-year alcohol use, and past-year problem drinking (e.g., 8+ on the Alcohol Use Disorders Identification Test)., Results: Past-year antidepressant use increased from 1999 to 2017 similarly among the full sample, past-year alcohol users, and past-year problem drinkers. Approximately 9% of Ontarians reported past-year antidepressant use in 2017. Overall, past-year problem drinkers were 1.5 times more likely to use antidepressants than non-problem drinkers. Past-year alcohol use was not associated with antidepressant use. Gender moderated the association between past-year problem drinking and antidepressant use., Conclusion: This study determined that past-year antidepressant use increased from 1999 to 2017, that past-year problem drinkers are more likely to use antidepressants than non-problem drinkers, and that past-year problem drinking is associated with past-year antidepressant use among women but not among men., (© 2021.

Background and Aims: Research shows that sensitivity to certain alcohol responses conveys risk for problem drinking. This study aimed to determine if high-risk adolescent drinkers infuse more alcohol and experience greater alcohol-induced stimulation and wanting and less sedation than low-risk adolescent drinkers., Design and Participants: Ninety-two low- (n = 38) and high-risk (n = 54) adolescent drinkers, as determined by Alcohol Use Disorders Identification Test scores of < 6 or ≥ 6, respectively, participated in the Dresden Longitudinal Study on Alcohol Use in Young Adults in which intravenous alcohol self-administration was examined in a mixed within- and between-subjects design., Setting: Technische Universität Dresden. Dresden, Germany., Measurements: Predictors were drinking status (high- versus low-risk), time and their interactions. Outcomes were arterial blood alcohol concentration (aBAC); alcohol-induced stimulation, sedation and wanting assessed at baseline, 10 (alcohol prime), 45, 65, 85, 105, 125 and 145 minutes. Covariates were family history of alcohol use disorder, sex and aBAC., Results: The alcohol prime dose produced similar sharp increases in stimulation and sedation in high- and low-risk drinkers (time P < 0.001; group × time P > 0.05). During self-administration, high-risk drinkers reached higher aBACs (P = 0.028) at a faster rate (group × time P < 0.001), and experienced further increases in stimulation (group × time P = 0.005) but with similar sedation (group × time P = 0.794) than in low-risk drinkers. High-risk drinkers also exhibited greater tonic alcohol wanting (group P = 0.003) throughout the session., Conclusions: High-risk adolescent drinkers appear to have heightened sensitivity to alcohol-induced stimulation and tonic high levels of wanting compared with low-risk adolescent drinkers., (© 2020 Society for the Study of Addiction.)

Objective: While the U.S. adult smoking rate has declined, Black smokers disproportionately face more barriers to accessing brief effective tobacco cessation treatments compared with other racial groups. This study developed and tested the effects of a novel, evidence-based, brief smoking intervention culturally targeted for disadvantaged Black smokers (ClinicalTrials.gov ID: NCT04460417). Method: In this randomized controlled trial, primarily low-income Black non-treatment-seeking smokers ( N = 204, 51% female) were randomized to enhanced care (EC) or treatment as usual (TAU). The EC group received a 30-min session with personal feedback on smoking, education on health outcomes and tobacco advertising targeting Black smokers, and nicotine replacement therapy (NRT) starter kits. TAU included provision of self-help materials. Primary outcome was motivation to change smoking behavior, and secondary outcomes included NRT knowledge and use, quit attempts, and number of cigarettes smoked per day. Data were collected at baseline, 1- and 6-month follow-ups. Results: Compared with TAU, EC increased motivation to change ( p = .02), accuracy in NRT knowledge, ( p < .001), NRT use ( p = .01), and likelihood of making a serious quit attempt as well as reduced cigarettes smoked per day ( p < .01) through 6-month follow-up. Conclusions: A brief motivational intervention for Black non-treatment-seeking smokers increased motivation to change smoking and resulted in improvements in NRT knowledge, use, and quit-relevant behaviors. Findings support cultural-targeting and provision of NRT to enhance motivation in Black smokers to reduce cultural and institutional barriers to tobacco cessation.

Impulsivity and subjective response (SR) to alcohol (i.e., individual differences in sensitivity to pharmacologic alcohol effects) are both empirically supported risk factors for alcohol use disorder; however, these constructs have been infrequently studied as related risk factors. The present investigation examined a self-report measure of impulsivity (i.e., the Barratt Impulsiveness Scale, Version 11) in relation to acute alcohol effects (i.e., stimulant and sedative SR). Participants came from 2 cohorts of the Chicago Social Drinking Project. Heavy and light drinkers from Cohort 1 (n = 156) and heavy social drinkers from Cohort 2 (n = 104) were examined using identical laboratory protocols following oral alcohol administration using a within-subject, double-blind, placebo-controlled laboratory study design. Self-reported impulsivity and, for comparison purposes, sensation seeking were measured at baseline, and SR was measured once prior to and 4 times following alcohol administration. More impulsive light, but not heavy, drinkers reported heightened stimulant SR following alcohol administration. High impulsive, light drinkers reported stimulant SR at a magnitude similar to that for heavy drinkers, whereas low impulsive, light drinkers reported limited stimulant SR. The interaction between impulsivity and sensation seeking did not statistically predict stimulant SR, and overall, impulsivity was a stronger predictor than was sensation seeking. However, impulsivity was not statistically predictive of dampened sedative SR among light or heavy drinkers. These findings partially replicate and extend the recent literature linking self-reported impulsivity to heightened stimulant SR from alcohol. Future directions include longitudinal studies and research relating multiple facets of impulsivity to SR. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Introduction: Despite tobacco use as the largest preventable cause of premature death in the US, many healthcare providers continue to lack the knowledge and confidence in employing the Ask, Advise, Refer (AAR) model in tobacco cessation treatment delivery. This pilot study evaluated the feasibility and effectiveness of a novel AAR-styled training program, Counsel to Quit®, across a range of healthcare providers and disciplines (i.e., medical, mental health, other). The Counsel to Quit® training program primarily targeted publically-funded settings that serve communities with high smoking rates., Methods: Pre- and post-training surveys were administered to medical, mental health, and other professionals (N = 297) to evaluate the effectiveness of the 60-90 minute Counsel to Quit® counselor training program for improving confidence in the ability to discuss approved tobacco cessation interventions and address the current state of knowledge about the role of electronic cigarettes in tobacco cessation. The trainings were held across 14 different non-profit institutional settings in Chicago, IL., Results: The Counsel to Quit® program improved AAR beliefs, the confidence and ability to discuss smoking cessation, and knowledge on the role of electronic cigarettes in tobacco cessation among medical, mental health, and other providers (ps < .001). Interactions showed that Counsel to Quit® improved medical provider confidence in referring patients for smoking cessation the most (p < .001), and also improved mental health providers belief in the importance of tobacco cessation for preventative care the most (ps < .05)., Conclusions: Counsel to Quit® is a feasible and effective training for improving AAR beliefs across multiple healthcare provider domains and at different types of publicly-funded healthcare institutions. Further, this training increased provider preparedness to discuss the lack of evidence for e-cigarette use as a form of tobacco cessation., (Copyright © 2019. Published by Elsevier Inc.)

Objective: Research evidence supports the clinical significance of subjective feelings of loss of control over eating; however, limited attention has been given to how this construct is assessed. Two measures have been developed in recent years (i.e., Eating Loss of Control Scale [ELOC] and Loss of Control over Eating Scale [LOCES]), but further validation in clinical and non-clinical samples is needed., Method: The current study evaluated the psychometric properties, including factor structure, criterion validity, and measurement invariance of the ELOC and LOCES across two groups: (a) a clinical sample of individuals with eating disorders (n = 106) and (b) a non-clinical sample of college students (n = 321)., Results: Confirmatory factor analyses indicated that the 16-item version of the ELOC and 7-item brief version of the LOCES provided good fit to the data in both samples. These measures were highly correlated (r = .83-.87) and associated with binge-eating and related psychopathology. The ELOC demonstrated partial invariance between men and women and between the clinical and non-clinical samples. The LOCES-brief demonstrated full invariance between men and women and partial invariance between the clinical and non-clinical samples., Discussion: Findings suggest that the 16-item ELOC and 7-item LOCES are reliable measures of severity of loss of control eating in clinical and non-clinical samples. Given the brevity of the LOCES-brief and evidence for measurement invariance across sex, it is recommended over the ELOC in heterogeneous samples. Future research is needed to confirm the validity of these measures across individuals with and without eating disorders., (© 2018 Wiley Periodicals, Inc.)

Background: Alcohol hangovers have been found to be a common and costly consequence of alcohol misuse. However, there is only limited psychometric support for instruments to accurately measure hangovers beyond the college-age years. This study investigated the psychometric properties of the Hangover Symptom Scale (HSS) and the Hangover Symptom Scale-Short Form (HSS-5) including the internal consistency, convergent and discriminant validity, construct validity, and the measurement invariance of these scales between light and heavy drinkers, individuals with a positive and negative family history of alcohol use disorder (AUD), and men and women in a post-college-aged sample. The association of the HSS and HSS-5 with alcohol use problems was also tested., Methods: Participants were 294 nonalcoholic light and heavy social drinkers (age range 21 to 35 years; 57.8% male) enrolled in the Chicago Social Drinking Project. They completed the HSS as part of a take-home packet completed outside of the laboratory. The psychometric properties of the HSS and HSS-5 were tested., Results: Stronger psychometric support was found for the HSS-5 relative to the full HSS. While both measures demonstrated strong internal consistency reliability, convergent and discriminant validity, and an association with alcohol use problems, only the HSS-5 showed construct validity as determined by confirmatory factor analysis. Further, only the HSS-5 showed measurement invariance between men and women, light and heavy drinkers, and individuals with a positive and negative family history of AUD., Conclusions: This was the first study to examine the psychometric properties of the HSS and HSS-5 in a post-college-aged sample and the first to investigate the measurement invariance of these measures as a function of sex, drinking history, and family history of AUD. This study supports the use of the HSS-5 as a reliable and valid brief measure of frequency of hangover symptoms., (Copyright © 2018 by the Research Society on Alcoholism.)

Background: Despite recent research establishing high rates of comorbidity between hoarding disorder and alcohol use disorders (AUD), no studies have systemically examined the associations between symptoms of hoarding and alcohol use. Moreover, no studies have explored potential mechanisms that may help to explain these relations., Objectives: Thus, the current study was designed to examine the associations between hoarding and AUD symptoms, as well as the mediating role of emotion dysregulation., Methods: Self-report measures of hoarding, depression, anxiety, alcohol use, and emotion regulation were collected in a sample of 574 adults (M age = 35.43, SD = 12.57; 62% female)., Results: Even when controlling for depression and anxiety, AUD symptoms were associated with overall hoarding severity (β =.23, p <.001) as well as acquiring symptoms (β =.16, p =.03). Further, the relation between hoarding symptoms and AUD symptoms was mediated by difficulties regulating emotions (B =.04, 95% CI [.02,.06]). Conclusions/Importance: Results of the current study suggest that increased alcohol use may be one way in which individuals with hoarding symptoms attempt to regulate their emotions.

Objectives: The study sought to compare the safety (resistance to damage) and efficacy (ability to cross the side branch) of polymer-coated and non-polymer-coated guidewires in the jailed wire technique used during the percutaneous treatment of bifurcation lesions., Background: The jailed wire technique is a useful strategy in the treatment of bifurcation lesions by provisional stenting. However, these wires can be damaged or even be broken during their removal., Methods: We performed a randomized study in patients with bifurcation lesions treated by provisional stenting. The jailed wire technique was mandatory, and the types of guidewires, polymer-coated (n = 115) and non-polymer-coated (n = 120), were randomized. After the procedures, the wires were evaluated by stereoscopic microscopy. The induced damage in the wires was classified as follows: no damage, mild, moderate, or severe., Results: The clinical characteristics were similar between patients treated with polymer-coated or non-polymer-coated wires. Polymer-coated wires were significantly (p < 0.001) more resistant to retrieval damage (only 2 wires showed mild damage) than were non-polymer-coated wires. However, 63 (55%) of the non-polymer-coated wires were damaged; 37 (32%), 24 (21%), and 2 (2%) had mild, moderate, and severe damage, respectively. Additionally, the jailed length of the wire was a factor contributing to the degree of wire damage. The time of side branch wiring was shorter in the polymer-coated wire group (19 ± 40 s vs. 42 ± 72 s; p < 0.05)., Conclusions: Jailed wires during interventional procedures of bifurcation lesions commonly showed microscopic damage. Polymer-coated wires were more resistant to retrieval damage and were more efficient in crossing the side branch ostium than non-polymer-coated wires.

Objective: Research on the progression from substance use to dependence typically relies on lifetime retrospective reports of dependence among ever users. We sought to evaluate probability and correlates of dependence among recent (past-year) weekly users of alcohol, nicotine, cannabis, and cocaine through cross-sectional and prospective analyses., Methods: Data on substance use (assessed by the Alcohol Use Disorder and Associated Disabilities Interview Schedule-IV) and DSM-IV psychiatric disorders were assessed in 2 waves (Wave 1, N = 43,093; Wave 2, N = 34,653) through the National Epidemiologic Survey on Alcohol and Related Conditions., Results: Conditional risk of dependence varied by frequency of substance use, although it was relatively stable for nicotine use. Among weekly past-year substance users at Wave 1, rates of dependence when rates of past-year dependence at Wave 1 were combined with new cases of dependence reported at Wave 2 were 15.6% for alcohol, 25.0% for cannabis, and 67.3% for nicotine. For past-year weekly users of cocaine at Wave 1, 49.9% met criteria for past-year dependence. Multiple demographic characteristics and past-year psychiatric disorders were correlated with past-year dependence, even among daily users. Men were generally more likely than women to be dependent on alcohol, cannabis, and cocaine, although women were more likely to be dependent on nicotine. Prospective analyses indicated that depressive disorders at Wave 1 predicted subsequent development of alcohol dependence (odds ratio [OR] = 1.40; 95% CI, 1.19-1.65; P < .05). Further, 33.5% of weekly tobacco smokers who were nondependent at Wave 1 developed dependence later on., Conclusions: The present findings highlight the importance of frequency of use when determining the addictiveness of substances and suggest that certain demographic variables and psychiatric disorders are associated with substance dependence even among regular substance users., (© Copyright 2016 Physicians Postgraduate Press, Inc.)

Growing interest in developing more effective smoking cessation treatments has facilitated the need to further investigate cognitive-affective factors that inhibit successful smoking cessation, such as urges to smoke. Research has strongly supported an association between suicidality and smoking, yet no work has investigated whether suicidality may increase urges to smoke. The current study sought to evaluate the impact of suicidality on smoking-related cognitive-affective factors predictive of smoking relapse among a community sample of 209 daily smokers engaged in a smoking cessation program. Structural equation modeling (SEM) was used to test the effects of self-reported pre-cessation suicidality on urges to smoke 1 month post-cessation as well as whether this effect was mediated by greater barriers to cessation. Results indicated that internal barriers to cessation significantly mediated the effect of pre-cessation suicidality on greater urges to smoke 1 month following smoking cessation attempt. These findings suggest that elevated suicidality may affect perceived internal barriers to cessation and subsequently urges to smoke 1 month following a quit attempt., (Copyright © 2015 Elsevier B.V.

Objective: The misuse of alcohol is related to numerous detrimental health effects. Research has determined anxiety sensitivity (AS) to be a risk factor for problematic alcohol use. To date, no studies have investigated this relationship using a bifactor model of AS. This study used a bifactor model to determine the effects of the general AS factor and the cognitive, physical, and social concerns subfactors on alcohol-related outcomes., Method: The sample consisted of 329 participants selected from a larger sample of individuals in a brief smoking-cessation intervention. Latent factor models were used to determine the effects of the bifactor model of AS on alcohol use behavior., Results: The general AS factor was significantly associated with alcohol use problems but not alcohol consumption. The AS subfactors of cognitive, physical, and social concerns were not significantly related to either alcohol variable., Conclusions: The findings are inconsistent with previous research that has found associations between the AS subfactors and alcohol-related outcomes. The use of a bifactor model of AS allowed the variance associated with AS to be parceled out of the subfactors, indicating that general AS accounts for the relationship between AS and alcohol misuse.

Background: The overuse of substances can lead to economic, physical, and social consequences. Previous research has demonstrated associations between time perspective and frequency of substance use, but no studies have investigated time perspective's effect on substance use consequences. This study aimed to fill this gap in the literature., Methods: Using an MTurk sample (N=531), latent factor models tested the hypothesis that both Present Hedonistic Time Perspective (PrHTP) and Past Negative Time Perspective PaNTP positively predict alcohol and illicit drug use consequences. Bootstrap analyses were then used to test the hypothesis that PrHTP indirectly affected the relationship between PaNTP and alcohol and illicit drug use consequences., Results: PrHTP significantly predicted alcohol and illicit drug use consequences. PaNTP also significantly predicted alcohol and illicit drug use consequences. PrHTP was found to indirectly affect the relationship between PaNTP and substance use consequences for both alcohol and illicit drugs., Conclusions: The findings are consistent with previous research and introduce time perspective as an individual differences risk factor for substance use consequences. The partial and full indirect effects are consistent with the idea that individuals with a PaNTP may develop a PrHTP, placing them at risk for substance use consequences., (Copyright © 2015 Elsevier Ireland Ltd.
