Background: Despite the evidence in support of the use of buprenorphine in the treatment of OUD and increasing ability of emergency medicine (EM) clinicians to prescribe it, emergency department (ED)-initiated buprenorphine is uncommon. Many EM clinicians lack training on how to manage acute opioid withdrawal or initiate treatment with buprenorphine. We developed a brief buprenorphine training program and assessed the impact of the training on subsequent buprenorphine initiation and knowledge retention., Methods: We conducted a pilot randomized control trial enrolling EM clinicians to receive either a 30-min didactic intervention about buprenorphine (standard arm) or the didactic plus weekly messaging and a monetary inducement to administer and report buprenorphine use (enhanced arm). All participants were incentivized to complete baseline, immediate post-didactic, and 90-day knowledge and attitude assessment surveys. Our objective was to achieve first time ED buprenorphine prescribing events in clinicians who had not previously prescribed buprenorphine in the ED and to improve EM-clinician knowledge and perceptions about ED-initiated buprenorphine. We also assessed whether the incentives and reminder messaging in the enhanced arm led to more clinicians administering buprenorphine than those in the standard arm following the training; we measured changes in knowledge of and attitudes toward ED-initiated buprenorphine., Results: Of 104 EM clinicians enrolled, 51 were randomized to the standard arm and 53 to the enhanced arm. Clinical knowledge about buprenorphine improved for all clinicians immediately after the didactic intervention (difference 19.4%, 95% CI 14.4% to 24.5%). In the 90 days following the intervention, one-third (33%) of all participants reported administering buprenorphine for the first time. Clinicians administered buprenorphine more frequently in the enhanced arm compared to the standard arm (40% vs. 26.3%, p = 0.319), but the difference was not statistically significant. The post-session knowledge improvement was not sustained at 90 days in the enhanced (difference 9.6%, 95% CI - 0.37% to 19.5%) or in the standard arm (difference 3.7%, 95% CI - 5.8% to 13.2%). All the participants reported an increased ability to recognize patients with opioid withdrawal at 90 days (enhanced arm difference .55, 95% CI .01-1.09, standard arm difference .85 95% CI .34-1.37)., Conclusions: A brief educational intervention targeting EM clinicians can be utilized to achieve first-time prescribing and improve knowledge around buprenorphine and opioid withdrawal. The use of weekly messaging and gain-framed incentivization conferred no additional benefit to the educational intervention alone. In order to further expand evidence-based ED treatment of OUD, focused initiatives that improve clinician competence with buprenorphine should be explored., Trial Registration: ClinicalTrials.gov Identifier: NCT03821103., (© 2022.

Research on Hispanic sleep (1) remains far behind research on non-Hispanic White sleep, and (2) seldom focuses solely on Hispanic women. A convergent parallel mixed-methods study design was used to examine (1) sleep quantity, quality, and habits; (2) the association of sleep and health; and (3) perceived barriers to healthy sleep in middle-aged Hispanic women living in [a large Midwest city]. A total of 78 Hispanic women were surveyed, and 27 of these Hispanic women participated in focus groups. Participants had: poor sleep quantity, quality, and sleep hygiene. In focus groups, participants identified three barriers to healthy sleep: poor sleep hygiene, responsibilities and related stress, and additional mental health concerns. While poor sleep quantity and quality have serious health consequences for Hispanic women, sleep disorders in Hispanic women have been understudied. This study underscores barriers to healthy sleep and the associations between sleep and health in Hispanic women., (© 2021.

Background: The survival benefit of negative margins for hepatocellular carcinoma (HCC) has been demonstrated. However, there is no consensus regarding the optimal resection margin width. We assessed the impact of hepatic resection margin width for solitary HCC on overall (OS), recurrence-free (RFS), and liver-specific recurrence-free survival (LSRFS)., Methods: Clinicopathologic data were retrospectively collected for solitary HCC patients who underwent a negative margin hepatectomy (1992-2015). Margin width was categorized in tertiles as "narrow" (≤ 0.3 cm), "intermediate" (0.31-1.0 cm), or "wide" (> 1.0 cm). Survival was compared among groups., Results: Of the 178 included patients, most were male (76%); median age, MELD score, and tumor size were 63 years, 8, and 5.2 cm, respectively; 93% were Child-Pugh class A. Median margin width was 0.5 cm. Median follow-up and OS were 47.8 months and 76.7 months, respectively. There was no significant survival difference among narrow, intermediate, and wide margin groups with a median OS of 53 months (IQR 21-not reached [NR]), 74 months (IQR 14-138), and 97 months (IQR 37-142) (p = 0.87), respectively. Median RFS was 33.0 months; again, there was no difference among narrow, intermediate, and wide margin groups with a median of 31 months (IQR 18-NR), 45 months (IQR 14-NR), and 27 months (IQR 11-NR), respectively (p = 0.66). Median LSRFS was 63.0 months (IQR 14-NR) with no difference among groups (p = 0.87). In multivariate analyses, margin width was not associated with OS (p = 0.77), RFS (p = 0.74), or LSRFS (p = 0.92). Findings were similar in all subgroups analyzed (≤ 5 cm, > 5 cm, microvascular invasion, T1, T2/T3, anatomical or non-anatomical resection, major or minor hepatectomy)., Conclusions: Narrow margins appear to be oncologically safe and the feasibility of achieving wide margins should not determine resectability., (© 2020.

Background: There is no consensus regarding the optimal surgical treatment for transplantable hepatocellular carcinoma (HCC) patients with well-compensated cirrhosis. Our aim was to compare outcomes between Child-Pugh A (CPA) cirrhotics who underwent liver resection or transplantation for HCC., Methods: Clinicopathologic data were retrospectively collected for all surgically treated HCC patients between 7/1992 and 12/2015. Disease-free survival (DFS) and overall survival (OS) were calculated from the time of operation or diagnosis (intention-to-treat analysis including patients removed from the transplant list). The average overall cost including pre-operative and post-operative procedures was calculated for each group., Results: Of the 513 surgically treated HCC patients, 184 had CPA cirrhosis and fulfilled the Milan criteria (MC). Of those, 95 (52%) were resected and 89 (48%) were transplanted. Twenty-two patients were removed from the transplant list. Transplanted patients were younger (p < 0.001), had a higher MELD score (p < 0.001) and a higher frequency of hepatitis C (p < 0.001). Length of stay and postoperative complication rates were similar between groups. DFS was longer for transplanted patients (3-, 5-, and 10-year DFS rates 48, 44, 31% vs 96, 94, 94%, respectively, p < 0.001). OS was similar between groups (3-, 5-, and 10-year OS rates 76, 62, 41% vs 82, 77, 53%, respectively, p = 0.07). Only size of greatest lesion and T stage were independent predictors of OS. The cost was much higher for the transplant group, even when accounting for the treatment of recurrences ($37,391 vs $137,996)., Conclusions: Since OS is similar between CPA cirrhotics within the MC undergoing resection or transplantation for HCC, but cost is significantly higher for transplantation. Resection should be considered for first-line treatment.

Background: Social networks influence obesity patterns, but interventions to leverage social incentives to promote weight loss have not been well evaluated., Objective: To test the effectiveness of gamification interventions designed using insights from behavioral economics to enhance social incentives to promote weight loss., Design: The Leveraging Our Social Experiences and Incentives Trial (LOSE IT) was a 36-week randomized, controlled trial with a 24-week intervention and 12-week follow-up., Participants: One hundred and ninety-six obese adults (body mass index ≥ 30) comprising 98 two-person teams., Interventions: All participants received a wireless weight scale, used smartphones to track daily step counts, formed two-person teams with a family member or friend, and selected a weight loss goal. Teams were randomly assigned to control or one of two gamification interventions for 36 weeks that used points and levels to enhance collaborative social incentives. One of the gamification arms also had weight and step data shared regularly with each participant's primary care physician (PCP)., Main Outcome Measures: The primary outcome was weight loss at 24 weeks. Secondary outcomes included weight loss at 36 weeks., Key Results: At 24 weeks, participants lost significant weight from baseline in the control arm (mean: - 3.9 lbs; 95% CI: - 6.1 to - 1.7; P < 0.001), the gamification arm (mean: - 6.6 lbs; 95% CI: - 9.4 to - 3.9; P < 0.001), and the gamification arm with PCP data sharing (mean: - 4.8 lbs; 95% CI: - 7.4 to - 2.3; P < 0.001). At 36 weeks, weight loss from baseline remained significant in the control arm (mean: - 3.5 lbs; 95% CI: - 6.1 to - 0.8; P = 0.01), the gamification arm (mean: - 6.3 lbs; 95% CI: - 9.2 to - 3.3; P < 0.001), and the gamification arm with PCP data sharing (mean: - 5.2 lbs; 95% CI: - 8.5 to - 2.0; P < 0.01). However, in the main adjusted model, there were no significant differences in weight loss between each of the intervention arms and control at either 12, 24, or 36 weeks., Conclusions: Using digital health devices to track behavior with a partner led to significant weight loss through 36 weeks, but the gamification interventions were not effective at promoting weight loss when compared to control., Trial Registration: clinicaltrials.gov Identifier: 02564445.

Background: Despite the benefits of influenza vaccination, each year more than half of adults in the United States do not receive it., Objective: To evaluate the association between an active choice intervention in the electronic health record (EHR) and changes in influenza vaccination rates., Design: Observational study., Patients: Adults eligible for influenza vaccination with a clinic visit at one of three internal medicine practices at the University of Pennsylvania Health System between September 2010 and March 2013., Intervention: The EHR confirmed patient eligibility during the clinic visit and, upon accessing the patient chart, prompted the physician and their medical assistant to actively choose to "accept" or "cancel" an order for the influenza vaccine., Main Measures: Change in influenza vaccination order rates at the intervention practice compared to two control practices for the 2012-2013 flu season, comparing trends during the prior two flu seasons adjusting for time trends and patient and clinic visit characteristics., Key Results: The sample (n = 45,926 patients) was 62.9% female, 35.9% white, and 54.4% black, with a mean age of 50.2 years. Trends were similar between practices during the 2 years in the pre-intervention period. Vaccination rates increased in both groups in the post-intervention year, but the intervention practice using active choice had a significantly greater increase than the control (adjusted difference-in-difference: 6.6 percentage points; 95% CI, 5.1-8.1; P < 0.001), representing a 37.3% relative increase compared to the pre-intervention period. More than 99.9% (9938/9941) of orders placed during the study period resulted in vaccination., Conclusions: Active choice through the EHR was associated with a significant increase in influenza vaccination rates.

After total gastrectomy, anastomosis-related complications such as leak or stricture can be highly morbid. Between July 2005 and December 2015, a linear-stapled side-to-side esophagojejunostomy with hand-sewn closure of the common enterotomy (modified Orringer technique) was used for Roux-en-Y reconstruction after prophylactic total gastrectomy in 22 germline CDH1 mutation carriers and after therapeutic total gastrectomy in 18 patients diagnosed with gastric adenocarcinoma. All operations were performed by the same surgeon. No patient in either cohort developed a clinically evident anastomotic leak, one patient (2.5%) developed a contained radiographic leak that healed without intervention, and one patient (2.5%) developed an anastomotic stricture treated by endoscopic dilatation 7 months after operation. These rates were lower than radiographic leak and stricture rates in a comparison group of 32 patients who received a completely hand-sewn esophagojejunostomy (6.3 and 3.1%, respectively). Here, we describe how to perform the linear-stapled esophagojejunostomy anastomosis.

Background: Changes in the medium of communication from paging to mobile secure text messaging may change clinical care, but the effects of these changes on patient outcomes have not been well examined., Objective: To evaluate the association between inpatient medicine service adoption of mobile secure text messaging and patient length of stay and readmissions., Design: Observational study., Participants: Patients admitted to medicine services at the Hospital of the University of Pennsylvania (intervention site; n = 8995 admissions of 6484 patients) and Penn Presbyterian Medical Center (control site; n = 6799 admissions of 4977 patients) between May 1, 2012, and April 30, 2014., Intervention: Mobile secure text messaging., Main Measures: Change in length of stay and 30-day readmissions, comparing patients at the intervention site to the control site before (May 1, 2012 to April 30, 2013) and after (May 1, 2013 to April 30, 2014) the intervention, adjusting for time trends and patient demographics, comorbidities, insurance, and disposition., Key Results: During the pre-intervention period, the mean length of stay ranged from 4.0 to 5.0 days at the control site and from 5.2 to 6.7 days at the intervention site, but trends were similar. In the first month after the intervention, the mean length of stay was unchanged at the control site (4.7 to 4.7 days) but declined at the intervention site (6.0 to 5.4 days). Trends were mostly similar during the rest of the post-intervention period, ranging from 4.4 to 5.6 days at the control site and from 5.4 to 6.5 days at the intervention site. Readmission rates varied significantly within sites before and after the intervention, but overall trends were similar. In adjusted analyses, there was a significant decrease in length of stay for the intervention site relative to the control site during the post-intervention period compared to the pre-intervention period (-0.77 days ; 95 % CI, -1.14, -0.40; P < 0.001). There was no significant difference in the odds of readmission (OR, 0.97; 95 % CI: 0.81, 1.17; P = 0.77). These findings were supported by multiple sensitivity analyses., Conclusions: Compared to a control group over time, hospitalized medical patients on inpatient services whose care providers and staff were offered mobile secure text messaging showed a relative decrease in length of stay and no change in readmissions.

Background: More than half of adults in the United States do not attain the minimum recommended level of physical activity to achieve health benefits. The optimal design of financial incentives to promote physical activity is unknown., Objective: To compare the effectiveness of individual versus team-based financial incentives to increase physical activity., Design: Randomized, controlled trial comparing three interventions to control., Participants: Three hundred and four adult employees from an organization in Philadelphia formed 76 four-member teams., Interventions: All participants received daily feedback on performance towards achieving a daily 7000 step goal during the intervention (weeks 1- 13) and follow-up (weeks 14- 26) periods. The control arm received no other intervention. In the three financial incentive arms, drawings were held in which one team was selected as the winner every other day during the 13-week intervention. A participant on a winning team was eligible as follows: $50 if he or she met the goal (individual incentive), $50 only if all four team members met the goal (team incentive), or $20 if he or she met the goal individually and $10 more for each of three teammates that also met the goal (combined incentive)., Main Measures: Mean proportion of participant-days achieving the 7000 step goal during the intervention., Key Results: Compared to the control group during the intervention period, the mean proportion achieving the 7000 step goal was significantly greater for the combined incentive (0.35 vs. 0.18, difference: 0.17, 95 % confidence interval [CI]: 0.07-0.28, p <0.001) but not for the individual incentive (0.25 vs 0.18, difference: 0.08, 95 % CI: -0.02-0.18, p = 0.13) or the team incentive (0.17 vs 0.18, difference: -0.003, 95 % CI: -0.11-0.10, p = 0.96). The combined incentive arm participants also achieved the goal at significantly greater rates than the team incentive (0.35 vs. 0.17, difference: 0.18, 95 % CI: 0.08-0.28, p < 0.001), but not the individual incentive (0.35 vs. 0.25, difference: 0.10, 95 % CI: -0.001-0.19, p = 0.05). Only the combined incentive had greater mean daily steps than control (difference: 1446, 95 % CI: 448-2444, p ≤ 0.005). There were no significant differences between arms during the follow-up period (weeks 14- 26)., Conclusions: Financial incentives rewarded for a combination of individual and team performance were most effective for increasing physical activity., Trial Registration: Clinicaltrials.gov identifier: NCT02001194.

Purpose: To update the oncologic outcomes and safety for microwave (MW) ablation of T1a (≤4.0 cm) and T1b (4.1-7.0 cm) renal cell carcinoma (RCC) with emphasis on tumor complexity and single session treatment., Materials and Methods: Retrospective review of 29 consecutive patients (30 tumors) with localized (NOMO) RCC (23 T1a; 7 T1b) treated with percutaneous MW ablation between 3/2013 and 6/2014. Primary outcomes investigated were technical success, local tumor progression (LTP), and complications. Technical success was assessed with contrast-enhanced computed tomography (CECT) immediately after MW ablation. Presence of LTP was assessed with CECT or contrast-enhanced magnetic resonance at 6-month target intervals for the first two years and annually thereafter. Complications were categorized using the Clavien-Dindo classification system., Results: Median tumor diameter was 2.8 cm [IQR 2.1-3.3] for T1a and 4.7 cm [IQR 4.1-5.7] for T1b tumors. Median RENAL nephrometry score was 7 [IQR 4-8] for T1a tumors and 9 [IQR 6.25-9.75] for T1b tumors. Technical success was achieved for 22 T1a (96%) and 7 T1b (100%) tumors. There were no LTP during a median imaging follow-up of 12.0 months [IQR 6-18] for the 23 patients (24 tumors) with greater than 6 months of follow-up. There were three Clavien-Dindo grade I-II complication (10%) and no Clavien-Dindo grade III-V complications (0%). All but two patients (93%) are alive without metastatic disease; two patients died after 12-month follow-up of causes unrelated to the MW ablation., Conclusion: Percutaneous MW ablation appears to be a safe and effective treatment option for low, moderate, and highly complex T1a and T1b RCC in early follow-up.

Background: Little is known about how well faculty at teaching hospitals role-model behaviors consistent with cost-conscious care., Objective: We aimed to evaluate whether residents and program directors report that faculty at their program consistently role-model cost-conscious care, and whether the presence of a formal residency curriculum in cost-conscious care impacted responses., Design: Cost-conscious care surveys were administered to internal medicine residents during the 2012 Internal Medicine In-Training Examination and to program directors during the 2012 Association of Program Directors in Internal Medicine Annual Survey. Respondents stated whether or not they agreed that faculty in their program consistently role-model cost-conscious care. To evaluate a more comprehensive assessment of faculty behaviors, resident responses were matched with those of the director of their residency program. A multivariate logistic regression model was fit to the outcome variable, to identify predictors of responses that faculty do consistently role-model cost-conscious care from residency program, resident, and program director characteristics., Participants: Responses from 12,623 residents (58.4 % of total sample) and 253 program directors (68.4 %) from internal medicine residency programs in the United States were included., Main Measures: The primary outcome measure was responses to questionnaires on faculty role-modeling cost-conscious care., Key Results: Among all responses in the final sample, 6,816 (54.0 %) residents and 121 (47.8 %) program directors reported that faculty in their program consistently role-model cost-conscious care. Among paired responses of residents and their program director, the proportion that both reported that faculty do consistently role-modeled cost-conscious care was 23.0 % for programs with a formal residency curriculum in cost-conscious care, 26.3 % for programs working on a curriculum, and 23.7 % for programs without a curriculum. In the adjusted model, the presence of a formal curriculum in cost-conscious care did not have a significant impact on survey responses (odds ratio [OR], 1.04; 95 % Confidence Interval [CI], 0.52-2.06; p value [p] = 0.91)., Conclusions: Responses from residents and program directors indicate that faculty at US teaching hospitals were not consistently role-modeling cost-conscious care. The presence of a formal residency curriculum in cost-conscious care did not impact responses. Future efforts should focus on placing more emphasis on faculty development and on combining curricular improvements with institutional interventions to adapt the training environment.

Fetal development in an obese maternal intrauterine environment has been shown to predispose the offspring for a number of metabolic disorders in later life. The observation that a large percentage of women of child-bearing age in the US are overweight/obese during pregnancy is therefore a source of concern. A high fat (HF) diet-induced obesity in female rats has been used as a model for maternal obesity. The objective of this study was to determine cellular development in brains of term fetuses of obese rats fed a HF diet from the time of weaning. Fetal brains were dissected out on gestational day 21 and processed for immunohistochemical analysis in the hypothalamic as well as extra-hypothalamic regions. The major observation of this study is that fetal development in the obese HF female rat induced several alterations in the HF fetal brain. Marked increases were observed in orexigenic signaling and a significant decrease was observed for anorexigenic signaling in the vicinity of the 3rd ventricle in HF brains. Additionally, our results indicated diminished migration and maturation of stem-like cells in the 3rd ventricular region as well as in the brain cortex. The results from the present study indicate developmental alterations in the hypothalamic and extra-hypothalamic regions in the HF fetal brain suggestive of a predisposition for the development of obesity and possibly neurodevelopmental abnormalities in the offspring.

United States health expenditures continue to escalate at unsustainable rates. A recent movement around increasing price transparency has been suggested as a way of reducing the rate of increase in expenditures, with legislative efforts taking place at both the state and federal level. While this seems on the surface like a good idea, simply providing information on prices to physicians, particularly trainees, may not achieve the type of large changes in practice patterns that proponents expect. The manner in which price transparency is implemented will likely play a significant role in its effectiveness as an intervention. In this article, the authors review efforts of transparency and default options from other contexts and leverage insights from behavioral economics to provide recommendations for increasing the likelihood that price transparency will lead to physicians weighing the relative value of interventions.

National efforts to improve the value of health care must include graduate medical education (GME) if they are to succeed. Proposals to teach residents to provide value-based care have come from the Medicare Payment Advisory Commission (MedPAC), the Accreditation Council for Graduate Medical Education (ACGME) and the American College of Physicians (ACP). Such proposals skip a key step: residency programs currently lack a clear strategy to prepare residents to assess and deliver value-based care. In this article, we present the VALUE Framework for programs to utilize to teach residents to assess and deliver value-based care for their patients. We then present more than 20 opportunities for residency programs to incorporate training in value-based care.

Background: Medicare Part D prescription drug plans (PDPs) implemented in January 2006 are designed to improve beneficiaries' access to pharmaceuticals and use market competition to yield affordable drug costs. Variations in estimated PDP costs for beneficiaries living in different states have not previously been characterized., Objective: To describe variations in the estimated costs of PDPs (plan premium, copays, and coinsurance) within and across states., Design: To estimate PDP costs based on 4 actual patient cases that exemplify common conditions and prescription drug combinations for Medicare beneficiaries, we used the online tool provided by the Centers for Medicare and Medicaid Services., Measurements: Principal study outcomes included (a) variation across states in the estimated annual cost of the lowest-cost PDP for each case and (b) variation in the estimated affordability of the lowest-cost PDPs across states, based on cost-of-living-adjusted median income for zero-earner households., Results: For all 4 patient cases, we found substantive within-state and between-state differences in the estimated costs of Medicare PDPs incurred by beneficiaries. The estimated annual costs to beneficiaries of the lowest-cost PDPs varied across states by as much as $320 for medications in the least expensive scenario, and by as much as $13,000 for the most expensive scenario. On average across states, a beneficiary with cost-of-living-adjusted median income would expect to spend 3%-28% of annual income to pay for medications in the lowest-cost PDPs in the 4 patient cases. The affordability of the lowest-cost plans varied across states, and for 2 of the 4 cases the lowest-cost PDP estimates were negatively correlated with cost-of-living-adjusted median income., Conclusions: Substantive differences in estimated PDP costs are evident across states for patients with common Medicare conditions. Importantly, the lowest-cost plans were not proportionally affordable with respect to state-specific cost-of-living-adjusted median income. Refinement of the Medicare drug program may be needed to improve national balance in PDP affordability for beneficiaries living in different states.

Vectors containing elements of the Epstein-Barr virus genome are used primarily to maintain cloned DNA inserts as plasmids in mammalian cells. However, Epstein-Bar-virus-based vectors have also been valuable tools in the hands of those studying the life cycle of Epstein-Barr virus. In this article, we discuss those characteristics of Epstein-Barr virus and its life cycle that have been used in vector construction and describe methods that are particularly applicable to the use of Epstein-Barr-virus-based vectors.
