RESUMO
Objective: We examined the change in pediatric primary care clinician attitudes and perceptions about telemedicine after one year of telemedicine use. Methods: We administered a survey to pediatric primary care clinicians across 50 primary care practices in Pennsylvania in 2020 and 2021. Surveys were linked using a combination of deterministic and probabilistic matching. We used McNemar's test to compare change in responses from 2020 to 2021. Results: Among pediatric primary care clinicians surveyed in 2020 and 2021 (n = 101), clinicians agreed that telemedicine could always or usually deliver high-quality care for mental health (80% in 2020 and 78% in 2021), care coordination (77% in 2020 and 70% in 2021), acute care (33% in 2020 and 34% in 2021), or preventive care (25% in 2020 and 18% in 2021) and this did not significantly change. Clinician perceptions of usability, while high, declined over time with fewer endorsing ease of use (93% in 2020 and 80% in 2021) and reliability (14% in 2020 and 0% in 2021) over time. Despite this, 62% of clinicians agreed that they were satisfied with their use of telemedicine at both time points. Respondents anticipated positive impact on equity and timeliness of care from telemedicine use but did not anticipate positive impact across child health, health care delivery, or clinician experience. Perceptions across these domains did not change over time. Conclusions: With one year of telemedicine experience, primary care clinicians maintained beliefs that telemedicine could deliver high-quality care for specific clinical needs but had worsening perceptions of usability over time.

Objective: Researchers from underrepresented groups leave research positions at a disproportionate rate. We aim to identify factors associated with self-efficacy in career advancement and career commitment among underrepresented post-doctoral fellows and early-career faculty. Methods: Building Up is a cluster-randomized trial with 25 academic health institutions. In September-October 2020, 219 Building Up participants completed the pre-intervention assessment, which included questions on demographics, science identity, mentoring, self-efficacy in career advancement (i.e., advancement is open to me, confidence in career progression, confidence in overcoming professional barriers), and career commitment (i.e., intent to continue research training or studying in a field related to biomedical sciences). Using logistic and multinomial logistic regression, we identified characteristics independently associated with self-efficacy in career advancement and career commitment. Results: The cohort is 80% female, 33% non-Hispanic/Latinx Black, and 34% Hispanic/Latinx. Having mentors that address diversity was significantly associated with the belief that advancement is open to them (OR = 1.7). Higher science identity (OR = 4.0) and having mentors that foster independence (OR = 1.8) were significantly associated with confidence in career progression. Higher science identity was also significantly associated with confidence in overcoming professional barriers (OR = 2.3) and intent to continue studying in a field related to biomedical sciences (OR = 3.3). Higher age (OR = 2.3) and higher science identity (OR = 4.2) were significantly associated with intent to continue research training. Discussion: Science identity and mentoring play key roles in self-efficacy in career advancement and career commitment. These factors may contribute to retention of underrepresented early-career biomedical researchers.
RESUMO
There have been numerous investigations of aberrant eating and substance abuse among patients who have undergone bariatric surgery, which affects the metabolism and the pharmacokinetics of alcohol. However, there is a dearth of literature considering the complex interplay between changes in post-surgery food and alcohol consumption. Furthermore, despite the increasing recognition of issues surrounding replacing food consumption with alcohol consumption (Food and Alcohol Disturbance [FAD]), most emerging research has focused on young adult populations. This perspective reviews and synthesizes the small but growing body of research on the interplay between food and alcohol consumption, particularly FAD, and considers its application to bariatric surgery in general. There are unique considerations for patients who have undergone bariatric surgery. Patients experience altered gastric anatomy, which affects food and alcohol metabolism, and are advised to abstain from drinking alcohol after surgery. After reviewing the available literature, this perspective highlights future directions for research and practice in bariatric surgery.
RESUMO
Introduction: Underrepresented researchers face more challenges than their well-represented counterparts. Perseverance and consistency of interest are associated with career success in well-represented physicians. Therefore, we examined associations of perseverance and consistency of interest with Clinical Research Appraisal Inventory (CRAI), science identity, and other factors related to career success among underrepresented post-doctoral fellows and early-career faculty. Methods: This is a cross-sectional analysis of data collected from September to October 2020 among 224 underrepresented early-career researchers at 25 academic medical centers in the Building Up Trial. We used linear regression to test associations of perseverance and consistency of interest scores with CRAI, science identity, and effort/reward imbalance (ERI) scores. Results: The cohort is 80% female, 33% non-Hispanic Black, and 34% Hispanic. The median perseverance and consistency of interest scores were 3.8 (25th-75th percentile: 3.7,4.2) and 3.7 (25th-75th percentile: 3.2, 4.0), respectively. Higher perseverance was associated with a higher CRAI score (ß = 0.82; 95% CI = 0.30, 1.33, p = 0.002) and science identity (ß = 0.44; 95% CI = 0.19, 0.68, p = 0.001). Higher consistency of interest was associated with a higher CRAI score (ß = 0.60; 95% CI = 0.23, 0.96, p = 0.001) and higher science identity score (ß = 0.20; 95% CI = 0.03, 0.36, p = 0.02), while lower consistency of interest was associated with imbalance favoring effort (ß = -0.22; 95% CI = -0.33, -0.11, p = 0.001). Conclusions: We found that perseverance and consistency of interest are related to CRAI and science identity, indicating that these factors may positively influence one's decision to stay in research.
RESUMO
PURPOSE: Few studies examine whether maternal and neonatal outcomes differ by time from metabolic and bariatric surgery (MBS) to conception. We describe maternal and neonatal outcomes among women with pregnancy after Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) overall and by whether conception occurred during the period when pregnancy is not recommended (< 18 months postoperative) versus later. MATERIALS AND METHODS: A prospective cohort study enrolled 135 US adult women (median age, 30 years, body mass index [BMI], 47.2 kg/m2) who underwent RYGB or SG (2006-2009) and subsequently reported ≥ 1 pregnancy within 7 years. Participants self-reported pregnancy-related information annually. Differences in prevalence of maternal and neonatal outcomes by postoperative conception timeframe (< 18 versus ≥ 18 months) were assessed. RESULTS: Thirty-one women reported ≥ 2 postoperative pregnancies. At time of postoperative conception (median 26 [IQR:22-52] months postoperative) median BMI was 31 (IQR:27-36) kg/m2. Excessive gestational weight gain (55%), cesarean section (42%) and preterm labor or rupture of membranes (40%) were the most common maternal outcomes. Forty percent of neonates had a composite outcome of still birth (1%), preterm birth (26%), small for gestational age (11%), or neonatal intensive care unit admission (8%). Prevalence of outcomes did not statistically significantly differ by timeframe. CONCLUSION: In US women who conceived ≤ 7 years following RYGB or SG, 40% of neonates had the composite neonatal outcome. The prevalence of maternal and neonatal outcomes post-MBS were not statistically significant by conception timeframe.

The COVID-19 pandemic had an immediate impact on the lives and work of early-career researchers. We leveraged a cluster-randomized trial and compared survey data collected over two timepoints to explore whether these impacts persisted. Although more than a year had passed, 74% of participants reported that their research was affected in multiple ways in both 2020 and 2021. These data suggest that the effects of the pandemic on early-career researchers may be prolonged. Our findings additionally serve as an impetus to identify and implement solutions to early-career challenges that undoubtedly existed before the pandemic, but which COVID-19 brought into the spotlight.
RESUMO
BACKGROUND: The aim of this study was to examine pediatric primary care telemedicine visit scheduling and attendance during the first year of telemedicine. METHODS: Using electronic health record data from two academic pediatric primary care practices between April 2020-March 2021, we used Pearson χ2 tests and logistic regression models to identify child-, family-, and appointment-level characteristics associated with scheduled and attended telemedicine appointments. RESULTS: Among 5178 primary care telemedicine appointments scheduled during the 12-month period, the proportion of appointments scheduled differed over time for children in families with a language preference other than English or Spanish (4% quarter 1 vs. 6% in quarter 4, p = 0.01) and residing in ZIP codes with the lowest household technology access (24% in quarter 1 vs. 19% in quarter 3 (p = 0.01). Four thousand one hundred and forty-eight of 5178 scheduled telemedicine appointments were attended. Likelihood of attending a telemedicine appointment was highest for children in families with a language preference other than English or Spanish (90%, 95% CI 86-94% compared to Spanish 74%, 95% CI 65-84%), and same-day appointments (86%, 95% CI 85-87%). Attendance among families preferring Spanish language was higher in later months compared to earlier months. CONCLUSIONS: We found disparities in scheduling and attending telemedicine appointments, but signs of greater language equity over time.

OBJECTIVE: Weight loss achieved with standard doses of glucagon-like peptide-1 (GLP-1) agonists among real-world patients with type 2 diabetes has not been determined. This study sought to describe the percent change in body weight 72 weeks after starting a GLP-1 agonist. METHODS: A retrospective cohort study of nonpregnant adults who were first dispensed a GLP-1 agonist between 2011 and 2018 was conducted using electronic health record data from patients receiving care at a large health system. Linear mixed models were used, with a person-level random intercept controlling for baseline variables associated with missing weight data to estimate percent body weight change during follow-up. RESULTS: The cohort included 2405 patients (mean [SD] age 48 [10] years, 53% female), with a mean BMI of 37 (8) kg/m2 and a mean baseline weight of 238 (54) lb. Mean percent weight loss significantly increased from 1.1% (95% CI: 0.6%-1.6%) 8 weeks after GLP-1-agonist dispensing to 2.2% (95% CI: 1.7%-2.6%) 72 weeks after GLP-1-agonist dispensing (p value for quadratic trend < 0.001). One-third of patients lost ≥5% body weight at 72 weeks. CONCLUSIONS: In this real-world study of more than 2400 patients with overweight or obesity and type 2 diabetes, starting a GLP-1 agonist at standard glycemic control doses was associated with modest weight loss through 72 weeks.

OBJECTIVE: To describe alcohol use, alcohol-related harm, and alcohol-related problems preoperatively and up to 8 years following metabolic and bariatric surgery (MBS) in adolescents. BACKGROUND: Risk for alcohol use and alcohol use disorders (AUD) increases post-Roux-en-Y gastric bypass and vertical sleeve gastrectomy in adults. However, data are lacking in adolescents who undergo MBS. METHODS: This study includes 217 adolescents (aged 13-19 y) enrolled in a 5-center prospective cohort study who underwent Roux-en-Y gastric bypass or vertical sleeve gastrectomy (2007-2011) and reported alcohol use preoperatively and annually postoperatively for up to 8 years. Time to elevated Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) score, alcohol-related harm, and alcohol-related problems were analyzed with Kaplan-Meier estimates of cumulative incidence. RESULTS: Preoperatively, the median age was 17 years; the median body mass index was 51 kg/m 2 . Alcohol use frequency and average quantity of drinks per drinking day increased postoperatively (2% consumed alcohol 2-4 times/month 6 months versus 24% 8 years postoperatively, P <0.001; 2% consumed≥3 drinks per drinking day 6 months versus 35% 8 years postoperatively, P <0.001). Cumulative incidence of postoperative onset elevated AUDIT-C score, alcohol-related harm, and alcohol-related problems at year 8 were 45% (95% CI:37-53), 43% (95% CI:36-51), and 47% (95% CI:40-55), respectively. CONCLUSIONS: Nearly half of those who underwent MBS as adolescents screened positively for AUD, symptoms of alcohol-related harm, or alcohol-related problems 8 years post-MBS, highlighting the risk for alcohol use and AUD after MBS in adolescents. AUD evaluation and treatment should be integrated into routine long-term care for adolescents undergoing MBS.

Introduction: Early-stage clinical and translational researchers who set and track career goals, milestones, and progress are successful in career development. We aimed to determine the effectiveness of the Customized Career Development Platform (CCDP), an online individual development plan (IDP), versus the traditional IDP template in improving research success and career satisfaction. Methods: We conducted a pragmatic cluster-randomized controlled trial of 340 scholars and trainees at 27 US academic healthcare institutions. The primary outcome was number of published manuscripts 24 months post-intervention. Secondary outcomes included the number of grant proposals submitted and funded, job satisfaction, and level of communication with mentors. An analysis of CCDP participants assessed proficiency level for the 14 Clinical and Translational Science Award (CTSA) competencies. Data were analyzed using intention-to-treat. Results: Participants were mostly female (60.3%) and Caucasian (67.2%); mean age was 34 years. Twenty-four months following the intervention, the CCDP versus traditional IDP groups showed a similar number of publications (9.4 vs 8.6), grants submitted (4.1 vs 4.4) and funded (1.3 vs 2.0), and job satisfaction score (3.6 vs 3.7). The CCDP group had higher odds of discussing communication (OR = 2.08) and leadership skills (OR = 2.62) and broadening their network (2.31) than the traditional IDP group. The CCDP arm reported improvements in 9 of the 14 CTSA competencies. Conclusion: The CCDP offers CTSA hubs an innovative alternative to traditional IDP tools. Future studies are needed to elucidate why the CCDP users did not fully appreciate or adopt the functionality of the online platform.
RESUMO
PURPOSE: The lack of racial and ethnic diversity in the biomedical workforce is pronounced and those from underrepresented backgrounds encounter more challenges than their majority counterparts. The extent of the impact of the COVID-19 pandemic on early-career investigators from underrepresented backgrounds is not yet fully understood. To examine the impact of the pandemic on underrepresented early-career biomedical researchers, this study evaluated differences in productivity, research, and psychological well-being by gender and career status. METHOD: This was a cross-sectional analysis of preintervention data, collected in September-October 2020, from 220 participants enrolled in the Building Up a Diverse Biomedical Research Workforce study. Participants were from 25 academic medical centers in the United States and were underrepresented early-career researchers. The primary outcomes were agreement on a 5-point Likert scale with pandemic impact statements (e.g., "The COVID-19 pandemic has impacted my ability to conduct research"). Thematic analysis was conducted on responses to 2 open-ended questions assessing the pandemic's impact. RESULTS: Most participants were female (79.9%), of non-Hispanic/Latinx/Spanish origin Black/African American (33.2%) or Hispanic/Latinx/Spanish origin (34.1%), and early-career faculty (53.4%). Over half of participants agreed or strongly agreed that the COVID-19 pandemic impacted their ability to work (55.7%) and conduct research (70.7%). Themes from qualitative analysis suggested lower research productivity, concerns about the academic job market and funding, and psychological distress due to the pandemic. Women were more likely to attribute lost productivity and psychological distress to homeschooling and childcare responsibilities. Postdoctoral fellows were concerned about more competition for fewer academic positions. CONCLUSIONS: In this study of early-career underrepresented biomedical researchers, the impact of the COVID-19 pandemic was widely felt by participants, varying by gender and career status. For those postdoctoral fellows and early-career faculty who are underrepresented, it is critical for institutions to offer flexibility in their positions.

Introduction: Social unrest tied to racism negatively impacted half of NIH-funded extramural researchers underrepresented (UR) in science. UR early-career scientists encounter more challenges in their research careers, but the impact of social unrest due to systemic racism in this group is unclear. We used mixed methods to describe the impact of social unrest due to systemic racism on mentoring relationships, research, and psychological well-being in UR post-doctoral fellows and early-career faculty. Methods: This is a cross-sectional analysis of data collected in September 2021-January 2022 from 144 UR early-career researchers from 25 academic medical centers in the Building Up Trial. The primary outcomes were agreement on five-point Likert scales with social unrest impact statements (e.g., "I experienced psychological distress due to events of social unrest regarding systemic racism"). Thematic analysis was conducted on responses to one open-ended question assessing how social unrest regarding systemic racism affected participants. Results: Most participants were female (80%), non-Hispanic Black (35%), or Hispanic (40%). Over half of participants (57%) experienced psychological distress as a result of social unrest due to systemic racism. Participants described direct and indirect discrimination and isolation from other persons of color at their institutions. Twice as many participants felt their mentoring relationships were positively (21%) versus negatively (11%) impacted by social unrest due to systemic racism. Conclusions: Experiences with racial bias and discrimination impact the career and well-being of UR early-career researchers. Mentoring relationships and institutional support play an important role in buffering the negative impact of racial injustice for this population.
RESUMO
Among a US cohort followed 5 years after Roux-en-Y gastric bypass or sleeve gastrectomy, cumulative incidence of marriage and separation/divorce were 18% among unmarried (N=614) and 13% among married (N=827) participants, respectively. Preoperative predictors of marriage included younger age, college degree, lower BMI and cohabitating or being separated (versus single). Objectives: To describe changes in marital status following Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Background: Spousal encouragement and finding a life partner are self-reported motivators for undergoing bariatric surgery. Methods: This study included 1441 US adults enrolled in a 6-center prospective cohort study who underwent RYGB or SG (2006-2009) and self-reported marital status preoperatively and annually postoperatively for ≤5 years. Time to change in marital status was analyzed with Kaplan-Meier estimates of cumulative incidence and Cox proportional-hazard models. Results: Preoperative, 57% of participants (79% female, median age 47 years, median body mass index [BMI] 47 kg/m2) were married, 5% cohabitating, 4% separated, 15% divorced, 2% widowed, and 17% always single. The 5-year cumulative incidence of marriage among unmarried participants (N = 614) was 18%. Cohabitating (hazard ratios [HR] = 5.25) or being separated (HR = 3.03) versus always single, younger age (HR = 1.69/10 years), having a college degree versus ≤high school (HR = 2.36), lower BMI (HR = 1.54/10kg/m2), and fewer depressive symptoms (HR = 1.47/10 Beck Depression Inventory points) preoperative independently predicted (P < 0.05) higher chance of marriage. The 5-year cumulative incidence of separation/divorce among married participants (N = 827) was 13%. Female sex (HR = 2.08), younger age (HR = 1.84/10 years), household income <$25,000 versus ≥$100,000 (HR = 2.48), smoking (HR = 1.76), and sexual desire ≥once/week versus never (HR = 2.12) preoperative independently predicted (P ≤ 0.05) separation/divorce. Conclusions: Among a cohort of US adults, the majority did not change marital status within 5 years following RYGB or SG. Cumulative incidence of marriage and separation/divorce was 18% among unmarried and 13% among married participants, respectively. Several preoperative predictors of marriage and separation/divorce were identified.
RESUMO
OBJECTIVE: The objective of this study was to compare the relative safety and effectiveness of invasive monitoring with subdural electrodes (SDEs) and stereoelectroencephalography (sEEG) in pediatric patients with drug-resistant epilepsy. METHODS: A retrospective cohort study was performed in 176 patients who underwent invasive monitoring evaluations at UPMC Children's Hospital of Pittsburgh between January 2000 and September 2021. To examine differences between SDE and sEEG groups, independent-samples t-tests for continuous variables and Pearson chi-square tests for categorical variables were performed. A p value < 0.1 was considered statistically significant. RESULTS: There were 134 patients (76%) in the SDE group and 42 (24%) in the sEEG group. There was a difference in the proportion with complications (17.9% in the SDE group vs 7.1% in the sEEG group, p = 0.09) and resection (75.4% SDE vs 21.4% sEEG, p < 0.01) between SDE and sEEG patients. However, there was no observable difference in the rates of postresection seizure freedom at 1-year clinical follow-up (60.2% SDE vs 75.0% sEEG, p = 0.55). CONCLUSIONS: These findings reveal a difference in rates of surgical complications and resection between SDEs and sEEG. Larger prospective, multi-institutional pediatric comparative effectiveness studies may further explore these associations.

Importance: Bariatric surgical procedures are associated with clinically important improvements (CIIs) in pain and physical function. However, there are declines in initial improvement by the third postoperative year, and the long-term durability of improvements are not well-described. Objective: To evaluate the durability of improvements in pain and physical function through 7 years after Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Design, Setting, and Participants: This study is part of the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2), a cohort study at 10 US hospitals. Adults with severe obesity (ie, body mass index of 35 or greater) undergoing bariatric surgery were assessed preoperatively (2006-2009) and followed up annually for as long as 7 years or until 2015. Of 1829 participants who underwent RYGB or SG in LABS-2, 338 were excluded from this study because they had a follow-up period of less than 5 years. Analysis of participants who underwent RYGB or SG and completed research assessments preoperatively and postoperatively for 5 to 7 years was conducted from March to April 2022. Main Outcomes and Measures: Preoperative-to-postoperative CIIs in pain and physical function scores from the 36-Item Short Form Health Survey and the Western Ontario McMaster Osteoarthritis Index, and 400-meter walk time, using previously established thresholds; and remission of mobility deficit, ie, inability to walk 400 meters in 7 minutes or less. Results: A total of 1491 individuals were included, with 1194 (80%) women; 59 (4%) Hispanic, 164 (11%) non-Hispanic Black, and 1205 (82%) non-Hispanic White individuals; a preoperative median (IQR) age of 47 (38-55) years; and a preoperative median (IQR) body mass index of 47 (42-52). Between 3 and 7 years after surgery, the percentage of participants with preoperative-to-postoperative CIIs in bodily pain decreased from 50% (95% CI, 48%-53%) to 43% (95% CI, 40%-46%), in physical function from 75% (95% CI, 73%-77%) to 64% (95% CI, 61%-68%), and in 400-meter walk time from 61% (95% CI, 56%-65%) to 50% (95% CI, 45%-55%). Among participants with a preoperative mobility deficit, remission decreased from 50% (95% CI, 42%-57%) to 41% (95% CI, 32%-49%), and among participants with severe knee or hip pain or disability, the percentage with CIIs in knee and hip pain and function decreased (eg, hip pain: from 77% [95% CI, 72%-82%] to 65% [95% CI, 58%-72%]; knee function: from 77% [95% CI, 73%-82%] to 72% [95% CI, 67%-77%]). Conclusions and Relevance: In this cohort study, despite decreases in preoperative-to-postoperative improvements across follow-up, CIIs in perceived bodily and joint-specific pain and in self-reported and objectively measured physical function ranged from 41% to 72%, depending on the measure and subgroup, 7 years after surgery, suggesting that RYGB and SG are commonly associated with long-term CIIs in pain and physical function.

OBJECTIVE: Complications from vagus nerve stimulator (VNS) procedures are common and can have important implications for morbidity and seizure control, yet predictors of complications are poorly understood. The objective of this study was to assess clinical factors associated with minor and major complications from VNS procedures among pediatric patients with drug-resistant epilepsy. METHODS: The authors performed an 11-year retrospective review of patients who underwent VNS procedures for drug-resistant epilepsy at age < 21 years. The primary outcome was complications (minor or major) following VNS surgery. Preoperative and surgery characteristics were compared between patients who developed versus those who did not develop complications. Multivariable Poisson regression was performed to determine the association between preoperative characteristics and infection. RESULTS: Of 686 surgeries, 48 complications (7.0%) developed; there were 7 minor complications (1.0%) and 41 major complications (6.0%). Surgeries with minor complications were an average of 68 minutes longer than those without minor complications (p < 0.001). The incidence rate of infection was 1 per 100 person-years, with 3% of procedures complicated by infection. Poisson regression revealed that after adjusting for age at surgery, duration of surgery, and primarily motor seizure semiology, the incident rate of infection for revision surgeries preceded by ≥ 2 procedures was 19 times that of first-time revisions. CONCLUSIONS: The overall minor complication rate was 1% and the overall major complication rate was 6% for VNS procedures. Longer surgery duration was associated with the development of minor complications but not major complications. Repeat incisions to the VNS pocket may be associated with higher incident rate of infection, highlighting a need for longer-lasting VNS pulse generator models.
RESUMO
OBJECTIVE: For epilepsy patients with drug-resistant, unresectable epilepsy, vagus nerve stimulation (VNS) is an option for seizure control. Approximately 40-70% of patients will achieve ≥50% seizure reduction with VNS. New closed loop VNS models detect ictal tachycardia and responsively stimulate the vagus nerve. The effectiveness of closed loop VNS compared to traditional VNS for pediatric epilepsy is unknown. METHODS: An 11-year retrospective electronic medical record review at Children's Hospital of Pittsburgh was performed. Patients with drug-resistant epilepsy who underwent VNS implantation were included. Patients were divided into groups based on VNS model: traditional versus closed loop. Those who transitioned from traditional to closed loop VNS were excluded. Given potential for selection bias, propensity scores matching was utilized to compare traditional to closed loop VNS patients. Patients with focal versus generalized epilepsy were also separately analyzed. The primary outcome was "VNS response", defined as at least 50% seizure frequency reduction from baseline. RESULTS: A total of 320 patients were included in this sample. The percentage of matched patients (total n = 220: n = 179 traditional VNS, n = 41 closed loop VNS) who responded to VNS after one year of therapy was 43% for traditional VNS and 39% for closed loop VNS (p = 0.64). After two years of therapy, a higher proportion of closed loop VNS patients than traditional VNS patients responded to VNS among all subgroups, though no differences were statistically significant (p>0.05). Notably, for those with generalized epilepsy, 73% of closed loop patients responded to VNS compared to only 46% of traditional patients (p = 0.10). After two years of VNS therapy, patients were taking approximately the same quantity of antiseizure medications as baseline (change of +0.074 +/- 0.90 ) with no difference between VNS models (p = 0.87). SIGNIFICANCE: Among pediatric patients with drug-resistant epilepsy, closed loop VNS trends towards a higher rate of VNS response after two years of treatment, especially among generalized epilepsy patients. Neither model of VNS allows patients to reduce antiseizure medication quantity after two years.

OBJECTIVE: To evaluate smoking history and change in smoking behavior, from 1 year before through 7 years after Roux-en-Y gastric bypass (RYGB) surgery, and to identify risk factors for post-surgery smoking. BACKGROUND: Smoking behavior in the context of bariatric surgery is poorly described. METHODS: Adults undergoing RYGB surgery entered a prospective cohort study between 2006 and 2009 and were followed up to 7 years until ≤2015. Participants (N = 1770; 80% female, median age 45 years, median body mass index 47âkg/m2) self-reported smoking history pre-surgery, and current smoking behavior annually. RESULTS: Almost half of participants (45.2%) reported a pre-surgery history of smoking. Modeled prevalence of current smoking decreased in the year before surgery from 13.7% [95% confidence interval (CI) = 12.1-15.4] to 2.2% (95% CI = 1.5-2.9) at surgery, then increased to 9.6% (95% CI = 8.1-11.2) 1-year post-surgery and continued to increase to 14.0% (95% CI = 11.8-16.0) 7-years post-surgery. Among smokers, mean packs/day was 0.60 (95% CI = 0.44-0.77) at surgery, 0.70 (95% CI = 0.62-0.78) 1-year post-surgery and 0.77 (95% CI = 0.68-0.88) 7-years post-surgery. At 7-years, smoking was reported by 61.7% (95% CI = 51.9-70.8) of participants who smoked 1-year pre-surgery (n = 221), 12.3% (95% CI = 8.5-15.7) of participants who formerly smoked but quit >1 year pre-surgery (n = 507), and 3.8% (95% CI = 2.1-4.9) of participants who reported no smoking history (n = 887). Along with smoking history (ie, less time since smoked), younger age, household income <$25,000, being married or living as married, and illicit drug use were independently associated with increased risk of post-surgery smoking. CONCLUSION: Although most adults who smoked 1-year before RYGB quit pre-surgery, smoking prevalence rebounded across 7-years, primarily due to relapse.

OBJECTIVE: To examine associations of objectively-measured physical activity (PA) with changes in weight after roux-en-Y gastric bypass (RYGB) over 7 years. BACKGROUND: The contribution of free-living PA to surgery-induced weight loss and subsequent weight regain is not well understood. METHODS: Participants of a multi-center prospective cohort study of bariatric surgery were followed annually ≥7 years. Of 807 participants who underwent RYGB and were given an activity monitor, 649 (80%) had sufficient data for this report (78% female; median age 47 years; median body mass index 46âkg/m2). Mean daily steps, hours/day in SB and minutes/week in moderate-to-vigorous physical activity (MVPA) were determined at each assessment. Mixed models tested associations between PA measures and weight outcomes, controlling for sociodemographics, health status, and eating behaviors. RESULTS: Across follow-up, mean pre to postsurgery changes in PA were small, and mean postsurgery PA level was below PA recommendations for health (eg, 101 MVPA min/week 7 years postsurgery versus the ≥150 MVPA min/week recommendation). There was a dose-response association between more steps, less SB and more MVPA with greater weight loss. Steps and SB, but not MVPA, were also associated with weight regain. For example, participants in the highest versus lowest steps quartile lost 2.9% (95% confidence interval, 1.8-4.1) more of their presurgery weight and regained 5.4% (95% confidence interval, 2.4-8.3) less of their maximum weight lost across follow-up. CONCLUSIONS: Despite only small increases in objectively-measured PA level after RYGB, PA level was independently associated with weight outcomes of bariatric surgery throughout 7 years of follow-up.

OBJECTIVE: To examine associations of objectively-measured free-living physical activity (PA) with changes in depressive symptoms and mental and physical health-related quality of life (HRQoL) over 7 years after Roux-en-Y gastric bypass surgery (RYGB). BACKGROUND: The contributions of PA to improvements in mental and physical health after RYGB, independent of weight loss, are unclear. METHODS: Adults undergoing RYGB in a US multi-center cohort study wore an activity monitor and completed the Beck depression inventory (BDI) and 36-Item Short Form Health Survey (SF-36) annually ≤7 years (N = 646; 78% female, median age 47 years, median body mass index 46kg/m 2 ). Linear mixed models estimated associations of quartiles of steps, sedentary behavior (SB), and moderate-to-vigorous intensity physical activity (MVPA), respectively, with pre-to-post-surgery changes in the BDI and SF-36 mental component summary and physical component summary scores, respectively, over 1-7 years post-surgery, with adjustment for sex, age, race, pre-surgerybody mass index, the respective pre-surgery score, treatment for depression (time-varying) and pre-to-post-surgery weight change (time-varying). RESULTS: There were dose-response associations between steps, SB (inverse) and MVPA quartiles, respectively, with improvements in each score. Across follow-up, mean improvements in the BDI, Mental Component Summary and physical component summary scores, were 1.9 [95% confidence interval (CI), 1.0-2.8], 3.1 (95% CI, 1.5-4.7), and 4.0 (95% CI, 2.7-5.4) points higher, respectively, in the highest versus lowest steps quartile. CONCLUSION: Among adults who underwent RYGB, multiple objective PA measures were associated with decreases in depressive symptoms and improvements in mental and physical HRQoL throughout 7 years, independent of weight loss, indicating PA is a modifiable behavior to augment outcomes.
