Problematic Behaviors and Predicting Online Risk Behaviors in High School Students.

Adolescent behavior now occurs offline and online. Frequently studied and treated independently, the relationship between offline problem behaviors and online risk taking is not well understood. This study asked whether there are any problematic behaviors predictive of online risk taking by high school students. Using a 2009 dataset of 2,077 high school students grades 9-12, five areas of offline problematic behaviors were examined: Academic problems, anxiety, behavioral wrongdoing, bullying, and social-emotional. Nine binary results were classified as online risk: Sexting, online harassment (perpetrating and experiencing), visiting sex sites, talking about sex, receiving sexual pictures, meeting offline, anything sexual happened, feeling nervous or uncomfortable. Behavioral wrongdoing (fighting, school suspension, trouble with police, theft), emerged as a significant predictor appearing in all nine models, followed by bullying experience (bully or victim) in six models. Identifying common problem behaviors that predict online risk taking are key components in developing strategies to promote adolescent health and well-being.

Transcutaneous carbon dioxide pattern and trend over time in preterm infants.

BACKGROUND: Chronic lung disease remains a burden for extremely preterm infants. The changes in ventilation over time and optimal ventilatory management remains unknown. Newer, non-invasive technologies provide insight into these patterns. METHODS: This single-center prospective cohort study enrolled infants ≤32 0/7 weeks. We obtained epochs of transcutaneous carbon dioxide (TcCO2) measurements twice each week to describe the pattern of hypercarbia throughout their hospitalization. RESULTS: Patterns of hypercarbia varied based on birth gestational age and post-menstrual age (PMA) (p = 0.03), regardless of respiratory support. Infants receiving the most respiratory support had values 16-21 mmHg higher than those on room air (p < 0.001). Infants born at the youngest gestational ages had the greatest total change but the rate of change was slower (p = 0.049) compared to infants born at later gestational ages. All infants had TcCO2 values stabilize by 31-33 weeks PMA, when values were not significantly different compared to discharge. No rebound was observed when infants weaned off invasive support. CONCLUSIONS: Hypercarbia improves as infants approached 31-33 weeks PMA. Hypercarbia was the highest in the most immature infants and improved with age and growth despite weaning respiratory support. IMPACT: This study describes the evolution of hypercarbia as very preterm infants grow and develop. The pattern of ventilation is significantly different depending on the gestational age at birth and post-menstrual age. Average transcutaneous carbon dioxide (TCO2) decreased over time as infants became more mature despite weaning respiratory support. This improvement was most significant in infants born at the lowest gestational ages.

Qualitative analysis of Amazon customer reviews of penile clamps for male urinary incontinence.

AIMS: Penile clamps offer an alternative to manage male urinary incontinence in patients who are unfit for surgery. Patient experience with penile clamps is poorly understood. Our study elucidates patient opinions on commercially available penile clamps and the factors that associate with favorable and unfavorable opinions. METHODS: We collected Amazon reviews of all penile clamps marketed for male urinary incontinence from November 2011 to January 2020 and qualitatively assessed the overall sentiment towards penile clamps, key praises and key complaints. Covariates such as designated Amazon star rating were further explored for association with coding patterns. RESULTS: Amazon reviews of penile clamps were found to be more positive (n = 425) in overall sentiment than negative (n = 294). The most frequent praise was effective incontinence control (n = 334) and the most frequent complaint was bad design or material (n = 166). The majority of reviews were for lower priced penile clamps, had higher Amazon star ratings, were written for Wiesner-produced clamps, and were written more recently (i.e., 2015-2020). Penile clamps with higher Amazon star ratings were more often coded positive and with a praise compared to lower rated penile clamps. CONCLUSIONS: Penile clamps are seen favorably by users as an effective treatment modality for male urinary incontinence. User reviews suggest opportunities for improvement in penile clamp design. The most frequently reviewed clamp seen positively is the Wiesner Incontinence Clamp Penile Clamp whereas the most frequently reviewed clamp seen negatively is the Pacey Cuff Male Incontinence Device.

Evaluating the primary use, strengths and weaknesses of pelvic floor muscle training devices available online.

AIMS: Treatment for urinary incontinence (UI) includes pelvic floor muscle training (PFMT). There is limited data appraising the characteristics of PFMT devices. We aimed to ascertain the primary use, strengths and weaknesses of PFMT devices available online, through evaluation of consumer reviews. METHODS: We performed an analysis of PFMT devices on Amazon.com. Four key device categories were recognized. Reviews from the five most frequently-reviewed products per category were analyzed (n = 20). W characterized device use, strengths and weaknesses using thematic analysis. RESULTS: We evaluated 2574 PFMT device reviews including 1168 vibrating Kegel balls, 750 non-vibrating Kegel balls, 411 pelvic floor or thigh exercisers, and 245 electric probes. Non-vibrating Kegel balls were rated highest (4.6/5 stars), followed by vibrating Kegel balls, electric probes and pelvic floor or thigh exercisers (4.4/5, 4.1/5, and 3.8/5 stars, respectively). Most reviews were positive (77%) or negative (16%) with few neutral (7%). While all were marketed to treat UI, most reviews did not mention the intended use. Vibrating and non-vibrating Kegel balls and electric probes were most likely to be used for UI, and pelvic floor or thigh exercisers for toning. Some used non-vibrating and vibrating Kegel balls for sexual function. Electric probes were the most beneficial device for incontinence control (27%, 67/245). Twenty-five percent of all product reviews praised device ease of use and good quality or design. A minority of reviewers found products difficult to use, of poor quality or design and uncomfortable. CONCLUSION: Consumers utilized online PFMT devices for multiple purposes, including UI, toning and sexual function. Reviewers generally praised PFMT products, particularly electric probes for UI.

Predicting outcomes in patients undergoing intra-articular corticosteroid hip injections.

OBJECTIVE: To investigate the associations between clinical, procedural, and radiographic factors and outcomes of steroid hip injections, including long-term and immediate pain reduction, time to arthroplasty, time to reinjection, and the total number of injections. MATERIALS AND METHODS: All intra-articular anesthetic and steroid injections of the hip under fluoroscopic guidance between January 2014 and March 2016 were retrospectively reviewed. Hip radiographs were scored using the Kellgren-Lawrence (KL) and Osteoarthritis Research Society International (OARSI) scores. Immediate pain relief and response were evaluated using a change in visual analog scale and OMERACT-OARSI criteria respectively. Long-term pain relief was evaluated at 2­7 months after injection by reviewing the medical records. Correlation between patient characteristics, procedural variations, and radiographic factors with injection outcomes was analyzed by using linear and logistic regression models. RESULTS: Of 361 injections, 79.8% showed an immediate pain response and 32.7% had subjective long-term pain relief (> 2 months). There was no significant correlation between immediate pain relief and response with long-term pain relief and other outcomes. Older age and higher KL score, OARSI-central joint space narrowing (JSN), and inferior acetabular osteophyte were correlated with long-term pain relief (p = 0.01­0.03). Higher KL and OARSI grades, particularly JSN, were significantly correlated with increased immediate pain relief and total number of injections but decreased time to arthroplasty. Baseline pain positively correlated with immediate pain response (p < 0.001). CONCLUSIONS: Older patients with higher grades of radiographic OA and high baseline pain were good candidates for steroid injections, particularly for those patients awaiting hip arthroplasty.

Teres minor muscle hypertrophy is a negative predictor of outcomes after reverse total shoulder arthroplasty: an evaluation of preoperative magnetic resonance imaging and postoperative implant position.

BACKGROUND: Predictors of outcomes after reverse total shoulder arthroplasty (rTSA) remain unclear. The purpose of this study was to analyze the impact of preoperative muscle quality and postoperative implant positioning on patient-reported outcomes following rTSA. METHODS: We evaluated 88 shoulders treated with rTSA in which preoperative magnetic resonance imaging was available. Preoperative muscle quality was evaluated, including fatty infiltration, rotator cuff muscle volume, and total tear size. Postoperative implant position was determined radiographically. The correlation between imaging parameters and the 2-year postoperative American Shoulder and Elbow Surgeons (ASES) score was examined. Multivariate analyses were performed to adjust for confounding factors including patient demographic characteristics and implant position. RESULTS: Univariate analysis showed that the ASES score was significantly lower in patients with teres minor muscle hypertrophy relative to those with normal muscle (73.3 ± 22.8 vs. 84.2 ± 16.9, P = .02). The functional subscore was significantly lower in patients with grade 2 fatty infiltration of the deltoid muscle relative to those with grade 0 fatty infiltration (26.1 ± 14.6 vs. 34.8 ± 11.6, P = .03). Older age was associated with a higher pain subscore (ρ = 0.32, P = .002). Multivariate analysis demonstrated that teres minor muscle hypertrophy remained a significant independent predictor of the ASES score (ß coefficient = 91.3, P = .03). CONCLUSION: Teres minor muscle hypertrophy is an independent negative predictor of patient-reported outcomes after rTSA.

Pubic Hair Grooming and Sexually Transmitted Infections: A Clinic-Based Cross-Sectional Survey.

BACKGROUND: Pubic hair grooming has been correlated with a self-reported history of sexually transmitted infections (STIs). We examined this relationship further in a cross-sectional survey of patients attending an urban STI clinic in San Francisco in 2018. METHODS: Pubic hair grooming practices and detailed sexual histories were obtained. Sexually transmitted infections were confirmed via laboratory diagnosis or physical examination by a licensed provider. RESULTS: A total of 314 individuals completed the survey. The median age of participants was 31 years. In total, there were 247 (80%) men, 58 (19%) women, and 5 (2%) transgender participants. Of the 247 men, 177 (72%) identified as gay or bisexual. Twenty-five (82%) of 314 patients reported pubic hair grooming within the past 3 months. Seventy-eight (25%) patients were diagnosed with a new STI during their visit. There were no significant associations between reporting any anal or genital grooming and being diagnosed with an STI. However, anal groomers were 3 times as likely to be diagnosed with a rectal STI after adjustment (adjusted odds ratio, 3.0; 95% confidence interval, 1.2-7.5) compared with genital only groomers and nongroomers. Participants who report removing all of their pubic hair more than 6 times within the past year had higher prevalence of genital STIs (33.3%, 6-10 times; 28.6%, >10 times) compared with participants who never groom all of their pubic hair (15.3%, P = 0.01). CONCLUSIONS: We found no association between recent grooming and genital STIs. Anal grooming was associated with rectal STIs in gay and bisexual men.

Clinical Outcomes of Periprocedural Antithrombotic Therapy in Ischemic Priapism Management.

BACKGROUND: Priapism is a urologic emergency consisting of a painful erection lasting greater than 4 hours; antithrombotic therapy (ATT) have recently been recommended as an adjunct in the treatment of ischemic priapism. AIM: To determine the short- and long-term outcomes of periprocedural ATT in the management of acute ischemic priapism. METHODS: A retrospective review of patients seen at the University of California, San Francisco, from 2008 to 2019 was carried out to identify those evaluated for acute priapism. Information regarding duration of priapism, etiology, treatment, periprocedural and postprocedural ATT type and dose, and follow-up data was collected. OUTCOMES: ATT use was the exposure of interest; outcome variables included priapism resolution, repeat episodes, long-term complications, and follow-up. RESULTS: 70 patients with at least 1 detailed record of an acute priapism episode between 2008 and 2019 were identified. Of the 70 patients who underwent management for an acute episode of priapism, 59 (84%) received intracavernous injection of phenylephrine with or without corporal aspiration. Of the 4 patients who received ATT at the same time as intracavernous injection, none had additional priapism episodes. In the 55 patients who did not receive immediate ATT, 22 (40%) required at least 1 shunting procedure. The 9 patients who received ATT concurrently with shunting experienced less recurrence than the 13 patients who did not receive ATT (11% vs 69%, respectively P = .012). There were no significant differences in long-term erectile dysfunction (P = .627), fibrosis (P = .118), genitourinary pain (P = .474), and urinary issues (P = .158) between those who received ATT and those who did not. CLINICAL IMPLICATIONS: Our findings suggest that ATT has a role in preventing priapism recurrence; we observed that long-term repeat priapism episodes are less frequent in those who received periprocedural ATT compared with those who did not and that ATT may especially reduce recurrence in cases when shunting was required STRENGTHS & LIMITATIONS: This is the first study looking at the clinical outcomes of periprocedural ATT in the management of ischemic priapism. It is limited by the fact that it is a single-center study, types of ATT were heterogenous, and the exact timing of priapism management could not be measured for everyone. CONCLUSION: In spite of its limitations, these preliminary findings are promising and warrant further exploration of the use of ATT in the management of ischemic priapism.

Long-Term Social Reintegration Outcomes for Burn Survivors With and Without Peer Support Attendance: A Life Impact Burn Recovery Evaluation (LIBRE) Study.

OBJECTIVE: To examine differences in long-term social reintegration outcomes for burn survivors with and without peer support attendance. DESIGN: Cross-sectional survey. SETTING: Community-dwelling burn survivors. PARTICIPANTS: Burn survivors (N=601) aged ≥18 years with injuries to ≥5% total body surface area (TBSA) or burns to critical areas (hands, feet, face, or genitals). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Life Impact Burn Recovery Evaluation Profile was used to examine the following previously validated 6 scale scores of social participation: Family and Friends, Social Interactions, Social Activities, Work and Employment, Romantic Relationships, and Sexual Relationships. RESULTS: Burn support group attendance was reported by 330 (55%) of 596 respondents who responded to this item. Attendees had larger burn size (43.4%±23.6% vs 36.8%±23.4% TBSA burned, P<.01) and were more likely to be >10 years from injury (50% vs 42.5%, P<.01). Survivors who attended at least 1 support group scored significantly higher on 3 of the scales: Social Interactions (P=.01), Social Activities (P=.04), and Work and Employment (P=.05). In adjusted analyses, peer support attendance was associated with increased scores on the Social Interactions scale, increasing scores by 17% of an SD (95% confidence interval, 1%-33%; P=.04). CONCLUSIONS: Burn survivors who reported peer support attendance had better social interaction scores than those who did not. This is the first reported association between peer support group attendance and improvements in community reintegration in burn survivors. This cross-sectional study prompts further exploration into the potential benefits of peer support groups on burn recovery with future intervention studies.

Impact of Work-Related Burn Injury on Social Reintegration Outcomes: A Life Impact Burn Recovery Evaluation (LIBRE) Study.

OBJECTIVE: To examine differences in long-term social reintegration outcomes for burn survivors with and without work-related injuries. DESIGN: Cross-sectional survey. SETTING: Community-dwelling burn survivors. PARTICIPANTS: Burn survivors (N=601) aged ≥18 years with injuries to ≥5% total body surface area or burns to critical areas (hands, feet, face, or genitals). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Life Impact Burn Recovery Evaluation Profile was used to examine the following previously validated 6 scale scores of social participation: Family and Friends, Social Interactions, Social Activities, Work and Employment, Romantic Relationships, and Sexual Relationships. RESULTS: Older participants, those who were married, and men were more likely to be burned at work (P<.01). Burn survivors who were injured at work scored significantly lower on the Work and Employment scale score after adjusting for demographic and clinical characteristics (P=.01). All other domain scale scores demonstrated no significant differences between groups. Individuals with work-related injuries scored significantly worse on 6 of the 19 items within the Work and Employment scale (P<.05). These individuals were more likely to report that they were afraid to go to work and felt limited in their ability to perform at work. CONCLUSIONS: Burn survivors with work-related injuries report worse work reintegration outcomes than those without work-related injuries. Identification of those at higher risk for work reintegration challenges after burn injury may enable survivors, providers, employers, and insurers to better use appropriate resources to promote and target optimal employment outcomes.

Role of Post-Acute Care on Hospital Readmission After High-Risk Surgery.

BACKGROUND: Payment models, including the Hospital Readmissions Reduction Program and bundled payments, place pressures on hospitals to limit readmissions. Against this backdrop, we sought to investigate the association of post-acute care after major surgery and readmission rates. METHODS: We identified patients undergoing high-risk surgery (abdominal aortic aneurysm repair, coronary bypass grafting, aortic valve replacement, carotid endarterectomy, esophagectomy, pancreatectomy, lung resection, and cystectomy) from 2005 to 2010 using the Healthcare Cost and Utilization Project's State Inpatient Database. The primary outcome was readmission rates after major surgery. Secondary outcome was readmission length of stay. RESULTS: We identified 135,523 patients of whom 56,720 (42%) received post-acute care. Patients receiving post-acute care had higher readmission rates than those who were discharged home (16% versus 10%, respectively; P < 0.001). The risk-adjusted readmission length of stay was greatest for patients who received care from a skilled nursing facility, followed by those who received home care, and lowest for those who did not receive post-acute care (7.1 versus 5.4 versus 4.8 d, respectively; P < 0.001). CONCLUSIONS: The use of post-acute care was associated with higher readmission rates and higher readmission lengths of stay. Improving the support of patients in post-acute care settings may help reduce readmissions and readmission intensity.

The comparative effectiveness of quadratus lumborum blocks and paravertebral blocks in radical cystectomy patients.

INTRODUCTION: Multimodal analgesia is an effective way to control pain and limit opioid use after surgery. The quadratus lumborum block and paravertebral block are two regional anesthesia techniques that leverage multimodal analgesia to improve postoperative pain control. We sought to compare the efficacy of these blocks for pain management following radical cystectomy. MATERIALS AND METHODS: We performed a retrospective review of radical cystectomy patients who received bilateral continuous paravertebral blocks (n = 125) or bilateral single shot quadratus lumborum blocks (n = 50) between 2014-2016. The primary outcome was postoperative opiate consumption on day 0. Secondary outcomes included self-reported pain scores and hospital length of stay. RESULTS: Quadratus lumborum block patients had similar opioid use on postoperative day 0 compared with paravertebral block patients (29 mg versus 30 mg, p = 0.90). Pain scores on postoperative day 0 were similar between quadratus lumborum block and paravertebral block groups (4.0 versus 3.8, p = 0.72); however, the paravertebral block group had lower pain scores on days 1-3 compared with the quadratus lumborum block group (all p < 0.05). Hospital length of stay was similar between groups (6.6 days versus 6.2 days, p = 0.41). CONCLUSIONS: There were no differences in opioid consumption among patients receiving bilateral single shot quadratus lumborum blocks and bilateral continuous paravertebral blocks after radical cystectomy. These data suggest that the quadratus lumborum block is a viable alternative for delivering multimodal analgesia in cystectomy patients.

Covalent Surface Modification of Silicon Oxides with Alcohols in Polar Aprotic Solvents.

Alcohol-based monolayers were successfully formed on the surfaces of silicon oxides through reactions performed in polar aprotic solvents. Monolayers prepared from alcohol-based reagents have been previously introduced as an alternative approach to covalently modify the surfaces of silicon oxides. These reagents are readily available, widely distributed, and are minimally susceptible to side reactions with ambient moisture. A limitation of using alcohol-based compounds is that previous reactions required relatively high temperatures in neat solutions, which can degrade some alcohol compounds or could lead to other unwanted side reactions during the formation of the monolayers. To overcome these challenges, we investigate the condensation reaction of alcohols on silicon oxides carried out in polar aprotic solvents. In particular, propylene carbonate has been identified as a polar aprotic solvent that is relatively nontoxic, readily accessible, and can facilitate the formation of alcohol-based monolayers. We have successfully demonstrated this approach for tuning the surface chemistry of silicon oxide surfaces with a variety of alcohol containing compounds. The strategy introduced in this research can be utilized to create silicon oxide surfaces with hydrophobic, oleophobic, or charged functionalities.

Rapid Covalent Modification of Silicon Oxide Surfaces through Microwave-Assisted Reactions with Alcohols.

We demonstrate the method of a rapid covalent modification of silicon oxide surfaces with alcohol-containing compounds with assistance by microwave reactions. Alcohol-containing compounds are prevalent reagents in the laboratory, which are also relatively easy to handle because of their stability against exposure to atmospheric moisture. The condensation of these alcohols with the surfaces of silicon oxides is often hindered by slow reaction kinetics. Microwave radiation effectively accelerates this condensation reaction by heating the substrates and/or solvents. A variety of substrates were modified in this demonstration, such as silicon oxide films of various thicknesses, glass substrates such as microscope slides (soda lime), and quartz. The monolayers prepared through this strategy demonstrated the successful formation of covalent surface modifications of silicon oxides with water contact angles of up to 110° and typical hysteresis values of 2° or less. An evaluation of the hydrolytic stability of these monolayers demonstrated their excellent stability under acidic conditions. The techniques introduced in this article were successfully applied to tune the surface chemistry of silicon oxides to achieve hydrophobic, oleophobic, and/or charged surfaces.

Tuning Oleophobicity of Silicon Oxide Surfaces with Mixed Monolayers of Aliphatic and Fluorinated Alcohols.

We demonstrate the formation of mixed monolayers derived from a microwave-assisted reaction of alcohols with silicon oxide surfaces in order to tune their surface oleophobicity. This simple, rapid method provides an opportunity to precisely tune the constituents of the monolayers. As a demonstration, we sought fluorinated alcohols and aliphatic alcohols as reagents to form monolayers from two distinct constituents for tuning the surface oleophobicity. The first aspect of this study sought to identify a fluorinated alcohol that formed monolayers with a relatively high surface coverage. It was determined that 1H,1H,2H,2H-perfluoro-1-octanol yielded high quality monolayers with a water contact angle (WCA) value of ∼110° and contact angle values of ∼80° with toluene and hexadecane exhibiting both an excellent hydrophobicity and oleophobicity. Tuning of the oleophobicity of the modified silicon oxide surfaces was achieved by controlling the molar ratio of 1H,1H,2H,2H-perfluoro-1-octanol within the reaction mixtures. Surface oleophobicity progressively decreased with a decrease in the fluorinated alcohol content while the monolayers maintained their hydrophobicity with WCA values of ∼110°. The simple and reliable approach to preparing monolayers of a tuned composition that is described in this article can be utilized to control the fluorocarbon content of the hydrophobic monolayers on silicon oxide surfaces.

A population-based study of the comparative effectiveness of second-generation antipsychotics vs older antimanic agents in bipolar disorder.

OBJECTIVES: Numerous antimanic treatments have been introduced over the past two decades, particularly second-generation antipsychotics (SGAs). However, it is not clear whether such newer agents provide any advantage over older treatments. METHODS: A historical cohort design investigated the nationwide population of outpatients with bipolar disorder treated in the Department of Veterans Affairs who were newly initiated on an antimanic agent between 2003 and 2010 (N=27 727). The primary outcome was likelihood of all-cause hospitalization during the year after initiation, controlling for numerous demographic, clinical, and treatment characteristics. Potential correlates of effect were explored by investigating time to initiation of a second antimanic agent or antidepressant. RESULTS: After control for covariates, those initiated on lithium or valproate monotherapy, compared to those beginning SGA monotherapy, were significantly less likely to be hospitalized, had a longer time to hospitalization, and had fewer hospitalizations in the subsequent year. Those on combination treatment had a significantly higher likelihood of hospitalization, although they also had a longer time to addition of an additional antimanic agent or antidepressant. CONCLUSIONS: The present analysis of a large and unselected nationwide population provides important complementary data to that from controlled trials. Although various mechanisms may be responsible for the results, the data support the utilization of lithium or valproate, rather than SGAs, as the initial antimanic treatment in bipolar disorder. A large-scale, prospective, randomized, pragmatic clinical trial comparing the initiation of SGA monotherapy to that of lithium or valproate monotherapy is a logical next step.

A randomized-controlled trial of high- or low-volume intravenous Plasma-Lyte(®) to prevent hypotension during sedation for colonoscopy.

PURPOSE: The purpose of this study was to compare the incidence of hypotension during sedation in adults presenting for elective colonoscopy and randomized to intravenous Plasma-Lyte 148(®) at either 2 mL·kg(-1) (low volume) or 20 mL·kg(-1) (high volume). METHODS: Patients aged ≥ 18 yr presenting for elective colonoscopy, with or without gastroscopy, after oral bowel preparation were randomized to receive the intervention immediately before the start of the procedure. Hypotension was defined as a ≥ 25% decrease in systolic blood pressure (SBP) from baseline during the procedure. Secondary outcomes included SBP < 90 mmHg, lowest SBP during sedation, duration of hypotension, use of vasopressors, postoperative outcomes, and cost. RESULTS: Seventy-five patients were randomly allocated to either the low-volume or high-volume group, respectively (total n = 150). The incidence of hypotension was similar in the two groups (59% vs 56%, respectively; odds ratio, 0.90; 95% confidence interval, 0.47 to 1.71; P = 0.74). The incidence of SBP < 90 mmHg, the lowest SBP during sedation, the duration of hypotension, the use of vasopressors, and postoperative outcomes were also similar in the two groups. CONCLUSIONS: This study does not support the routine use of 20 mL·kg(-1) of intravenous Plasma-Lyte 148 to prevent hypotension and other complications during sedation for elective colonoscopy in adult patients.

The Ascendancy of Second-Generation Antipsychotics as Frontline Antimanic Agents.

INTRODUCTION: Knowledge of the factors affecting the adoption of new medications can enhance mental health care and guide quality improvement and policy development. Food and Drug Administration indications for treating bipolar disorder with several second-generation antipsychotics (SGAs) in the 2000s represent an opportunity to identify factors that impact the spread of a then-innovative treatment through a new population. METHODS: Analysis of Department of Veterans Affairs administrative data identified the population of 170,811 veterans diagnosed with bipolar disorder from 2003 to 2010. We analyzed time trends and predictors of antimanic choice (SGA vs other) among the 40,512 outpatients with bipolar disorder who initiated their first VA outpatient antimanic prescription, using multinomial logistic regression in month-by-month analyses. We conducted classwise analyses and investigated prespecified predictors among specific agents. RESULTS: In classwise analyses, SGAs supplanted lithium, valproate, and carbamazepine/oxcarbazepine as the most commonly initiated antimanics by 2007. Psychosis, but not other indices of severity, predicted SGA initiation. Demographic analyses did not identify substantial disparities in initiation of SGAs. Drug-specific analyses revealed some consideration of medical comorbidities in choosing among specific antimanic agents, although effect sizes were small. Most patients initiating an antimanic had received an antidepressant in the previous year. DISCUSSION: Second-generation antipsychotics quickly became the frontline antimanic treatment for bipolar disorder, although antidepressants most commonly predated antimanic prescriptions. Second-generation antipsychotics were used for a broad range of patients rather than being restricted to a severely ill subpopulation. The modest association of antimanic choice with relevant medical comorbidities suggests that continued attention to quality prescribing practices is warranted.

Validation of the Community Integration Questionnaire in the adult burn injury population.

PURPOSE: With improved survival, long-term effects of burn injuries on quality of life, particularly community integration, are important outcomes. This study aims to assess the Community Integration Questionnaire's psychometric properties in the adult burn population. METHODS: Data were obtained from a multicenter longitudinal data set of burn survivors. The psychometric properties of the Community Integration Questionnaire (n = 492) were examined. The questionnaire items were evaluated for clinical and substantive relevance; validation procedures were conducted on different samples of the population; construct validity was assessed using exploratory factor analysis; internal consistency reliability was examined using Cronbach's α statistics; and item response theory was applied to the final models. RESULTS: The CIQ-15 was reduced by two questions to form the CIQ-13, with a two-factor structure, interpreted as self/family care and social integration. Item response theory testing suggests that Factor 2 captures a wider range of community integration levels. Cronbach's α was 0.80 for Factor 1, 0.77 for Factor 2, and 0.79 for the test as a whole. CONCLUSIONS: The CIQ-13 demonstrates validity and reliability in the adult burn survivor population addressing issues of self/family care and social integration. This instrument is useful in future research of community reintegration outcomes in the burn population.

Ethnic and gender diversity in hand surgery trainees.

PURPOSE: To evaluate whether the lack of diversity in plastic and orthopedic surgery persists into hand surgery through assessment of trainee demographics. METHODS: Demographic data were obtained from compilations on graduate medical education by the Journal of the American Medical Association. Ethnic diversity was assessed using the proportions of minority trainees. We analyzed the trends in ethnic diversity in hand, orthopedic, and plastic surgery from 1995 to 2012 by evaluating changes in proportions of African American, Hispanic, and Asian trainees. In addition, we compared the proportions of minority trainees in various surgical specialties during 2009 to 2012. Trends in gender diversity were similarly analyzed using the proportions of female trainees. RESULTS: During 1995 to 2012, the proportions of minority and female trainees increased significantly in the fields of orthopedic, plastic, and hand surgery. To assess the current state of diversity in various specialties, we compared minority and female population proportions using pooled 2009 to 2012 data. The percentage of non-Caucasian trainees in hand surgery was significantly higher than that in orthopedic sports medicine and orthopedic surgery and significantly lower than in general surgery. The percentage of female trainees in hand surgery was significantly higher than that in orthopedic sports medicine and orthopedic surgery and significantly lower than in plastic and general surgery. CONCLUSIONS: Ethnic and gender diversity in hand surgery increased significantly between 1995 and 2012. Women constitute a fifth of hand surgery trainees. Efforts to increase diversity should be further pursued using proven strategies and innovating new ones. CLINICAL RELEVANCE: Diversity in the medical field has shown to be a beneficial factor in many aspects including research productivity and patient care. Understanding how the field of hand surgery has changed with regard to the diversity of its trainees may aid in providing more equitable and effective health care.
