Impact of a digital employer-based weight loss program on individuals age 65 or older.

Introduction: Older adults are not protected from obesity, which has been linked to frailty, cognitive impairment, and other aging-related factors. Intensive lifestyle interventions have been shown to be effective for weight loss in older adults; however, these have typically been highly intensive and less feasible for dissemination. This analysis describes weight loss in a large-scale, commercially available, digital intervention in a subset of older adults. Methods: Older adults (N = 20,443, males = 6,238; females = 14,205) between 65 and 85 years of age with overweight (43.3%) or obesity (46.7%) participated in an online, self-directed weight loss program. Behavioral-based content was delivered through weekly video lessons within an online platform that included weight and physical activity tracking, an online community, a reference library, and access to coaching support. Self-reported measures taken at the time of entry into the program were used for this analysis (demographics, height, body weight, and health status). Weight was reported across weeks of engagement in the curriculum. Results: The average weight loss was -3.15 kg (95% CI: [-3.20, -3.11]) at 15.5 weeks. Weight loss was significantly greater in male individuals (-3.79 kg [95% CI: -3.89, -3.71]) versus female individuals (-2.87 kg [95% CI: -2.94, -2.82]) (p < 0.001), with a similar engagement in curriculum weeks. Percent weight loss was statistically significant for all age categories (p < 0.05) and self-reported health conditions (p < 0.05). Discussion: Short-term weight loss was observed in older adults exposed to a low-touch, self-guided, and digital behavioral-based weight loss program. Weight loss was also observed even in the presence of various chronic health conditions.

IDH1 inhibition potentiates chemotherapy efficacy in pancreatic cancer.

Pancreatic ductal adenocarcinoma (PDAC) is associated with a five-year overall survival rate of just 13%, and development of chemotherapy resistance is nearly universal. PDAC cells overexpress wild-type IDH1 that can enable them to overcome metabolic stress, suggesting it could represent a therapeutic target in PDAC. Here, we found that anti-IDH1 therapy enhanced the efficacy of conventional chemotherapeutics. Chemotherapy treatment induced ROS and increased TCA cycle activity in PDAC cells, along with the induction of wild-type IDH1 expression as a key resistance factor. IDH1 facilitated PDAC survival following chemotherapy treatment by supporting mitochondrial function and antioxidant defense to neutralize reactive oxygen species through the generation of alpha-ketoglutarate and NADPH, respectively. Pharmacologic inhibition of wild-type IDH1 with ivosidenib synergized with conventional chemotherapeutics in vitro and potentiated the efficacy of sub-therapeutic doses of these drugs in vivo in murine PDAC models. This promising treatment approach is translatable through available and safe oral inhibitors and provides the basis of an open and accruing clinical trial testing this combination (NCT05209074).

The Impact of Three-Dimensional Humeral Planning and Standard Transfer Instrumentation on Reconstruction of Native Humeral Anatomy for Anatomic Total Shoulder Arthroplasty.

BACKGROUND: Preoperative three-dimensional CT-based planning for anatomic total shoulder arthroplasty (TSA) has grown in popularity in the past decade with the primary focus on the glenoid. Little research has evaluated if humeral planning has any effect on the surgical execution of the humeral cut or the positioning of the prosthesis. METHODS: Three surgeons performed a prospective study utilizing 3D-printed humeri printed from CTs of existing patients, which were chosen to be -3, -1, 0, 1 and 3 standard deviations of all patients in a large database. A novel 3D printing process was utilized to 3D print not only the humerus, but also all four rotator cuff tendons. For each surgical procedure, the printed humerus was mounted inside a silicon shoulder, with printed musculature and skin, and with tensions similar to human tissue requiring standard retraction and instruments to expose the humerus. Three phases of the study were designed: Phase 1: Humeral neck cuts were performed on all specimens without any preoperative humeral planning, Phase 2: 3D planning was performed, and the cuts and implant selection were repeated, Phase 3: A neck shaft angle guide and digital calipers were used to measure humeral osteotomy thickness to aid in the desired humeral cut. All humeri were digitized. The difference between the prosthetic center of rotation (COR) and ideal COR was calculated. The percentage of patients with a varus neck shaft angle (NSA) was calculated for each phase. The difference in planned and actual cut thickness was also compared. RESULTS: For both 3D change in COR and medial to lateral change in COR, use of preoperative planning alone and with standard transfer instrumentation resulted in a significantly more anatomic restoration of ideal COR. The deviations from planned cut thickness decreased with each phase: Phase 1: 2.6±1.9 mm, Phase 2: 2.0±1.3 mm, Phase 3: 1.4±0.9 mm (p = 0.041 for Phase 3 vs Phase 1). For NSA, in Phase 1: 7/15 (47%) cases were in varus, in Phase 2: 5/15 (33%) were in varus and Phase 3: 1/15 (7%) were in varus (p =0.013 for Phase 3 vs Phase 1). CONCLUSIONS: Use of preoperative 3-D humeral planning for stemless anatomic TSA improved prosthetic humeral center of rotation, whether performed with or without standard transfer instrumentation. The use of a neck-shaft angle cut guide and calipers to measure cut thickness significantly reduced the percentage of varus humeral cuts and deviation from planned cut thickness.

Secret disclosure and social relationships in groups.

Personal secrets are a ubiquitous fact of group life, but the conditions under which they are revealed have not been explored. In five studies, we assessed secret disclosure in groups governed by four models of human sociality (Communal Sharing, Equality Matching, Authority Ranking, Market Pricing; Fiske). In Studies 1a and 1b, participants indicated their willingness to disclose secrets in hypothetical groups governed by the models. In Studies 2a and 2b, participants rated how much a group in which they disclosed secrets or nonsecrets is governed by the models. In Study 3, participants indicated their disclosure of various types of secrets in Communal Sharing and Equality Matching groups to which they belonged. Across studies, disclosure was most strongly associated with Communal Sharing, followed by Equality Matching. Study 3 further showed that identity fusion predicted disclosure in these two kinds of groups. Implications for understanding disclosure of personal secrets in group contexts were discussed.

Trajectories of illness uncertainty among parents of children with atypical genital appearance due to differences of sex development.

OBJECTIVE: The present study aimed to identify distinct trajectories of parental illness uncertainty among parents of children born with atypical genital appearance due to a difference of sex development over the first year following diagnosis. It was hypothesized that four trajectory classes would emerge, including "low stable," "high stable," "decreasing," and "increasing" classes, and that select demographic, familial, and medical factors would predict these classes. METHODS: Participants included 56 mothers and 43 fathers of 57 children born with moderate to severe genital atypia. Participants were recruited from eleven specialty clinics across the U.S. Growth mixture modeling (GMM) approaches, controlling for parent dyad clustering, were conducted to examine classes of parental illness uncertainty ratings over time. RESULTS: A three-class GMM was identified as the best-fitting model. The three classes were interpreted as "moderate stable" (56.8%), "low stable" (33.0%), and "declining" (10.3%). Findings suggest possible diagnostic differences across trajectories. CONCLUSIONS: Findings highlight the nature of parents' perceptions of ambiguity and uncertainty about their child's diagnosis and treatment the year following their child's birth/diagnosis. Future research is needed to better understand how these trajectories might shift over the course of the child's development. Results support the development of tailored, evidence-based interventions to address coping with uncertainty among families raising a child with chronic health needs.

Optimizing Opioid Prescription Quantity After Cesarean Delivery: A Randomized Controlled Trial.

OBJECTIVE: To test whether an individualized opioid-prescription protocol (IOPP) with a shared decision-making component can be used without compromising postcesarean pain management. METHODS: In this multicenter randomized controlled noninferiority trial, we compared IOPP with shared decision making with a fixed quantity of opioid tablets at hospital discharge. We recruited at 31 centers participating in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Maternal-Fetal Medicine Units Network. Study participants had uncomplicated cesarean births. Follow-up occurred through 12 weeks postdischarge. Individuals with complicated cesarean births or history of opioid use in the pregnancy were excluded. Participants were randomized 1:1 to IOPP with shared decision making or fixed quantity (20 tablets of 5 mg oxycodone). In the IOPP group, we calculated recommended tablet quantity based on opioid use in the 24 hours before discharge. After an educational module and shared decision making, participants selected a quantity of discharge tablets (up to 20). The primary outcome was moderate to severe pain (score 4 or higher [possible range 0-10]) on the BPI (Brief Pain Inventory) at 1 week after discharge. A total sample size of 5,500 participants was planned to assess whether IOPP with shared decision making was not inferior to the fixed quantity of 20 tablets. RESULTS: From September 2020 to March 2022, 18,990 individuals were screened and 5,521 were enrolled (n=2,748 IOPP group, n=2,773 fixed-quantity group). For the primary outcome, IOPP with shared decision making was not inferior to fixed quantity (59.5% vs 60.1%, risk difference 0.67%; 95% CI, -2.03% to 3.37%, noninferiority margin -5.0) and resulted in significantly fewer tablets received (median 14 [interquartile range 4-20] vs 20, P<.001) through 90 days postpartum. CONCLUSION: Compared with fixed quantity, IOPP with shared decision making was noninferior for outpatient postcesarean analgesia at 1 week postdischarge and resulted in fewer prescribed opioid tablets at discharge.

A decay-modeled compressed sensing reconstruction approach for non-Cartesian hyperpolarized 129Xe MRI.

PURPOSE: Hyperpolarized 129Xe MRI benefits from non-Cartesian acquisitions that sample k-space efficiently and rapidly. However, their reconstructions are complex and burdened by decay processes unique to hyperpolarized gas. Currently used gridded reconstructions are prone to artifacts caused by magnetization decay and are ill-suited for undersampling. We present a compressed sensing (CS) reconstruction approach that incorporates magnetization decay in the forward model, thereby producing images with increased sharpness and contrast, even in undersampled data. METHODS: Radio-frequency, T1, and T 2 * $$ {\mathrm{T}}_2^{\ast } $$ decay processes were incorporated into the forward model and solved using iterative methods including CS. The decay-modeled reconstruction was validated in simulations and then tested in 2D/3D-spiral ventilation and 3D-radial gas-exchange MRI. Quantitative metrics including apparent-SNR and sharpness were compared between gridded, CS, and twofold undersampled CS reconstructions. Observations were validated in gas-exchange data collected from 15 healthy and 25 post-hematopoietic-stem-cell-transplant participants. RESULTS: CS reconstructions in simulations yielded images with threefold increases in accuracy. CS increased sharpness and contrast for ventilation in vivo imaging and showed greater accuracy for undersampled acquisitions. CS improved gas-exchange imaging, particularly in the dissolved-phase where apparent-SNR improved, and structure was made discernable. Finally, CS showed repeatability in important global gas-exchange metrics including median dissolved-gas signal ratio and median angle between real/imaginary components. CONCLUSION: A non-Cartesian CS reconstruction approach that incorporates hyperpolarized 129Xe decay processes is presented. This approach enables improved image sharpness, contrast, and overall image quality in addition to up-to threefold undersampling. This contribution benefits all hyperpolarized gas MRI through improved accuracy and decreased scan durations.

Factors associated with tracheostomy-associated infection treatment: A multicenter observational study.

OBJECTIVE: To characterize factors that influence the decision to treat suspected pediatric bacterial tracheostomy-associated respiratory infections (bTRAINs; e.g., pneumonia, tracheitis). METHODS: We conducted a multicenter, prospective cohort study of children with pre-existing tracheostomy hospitalized at six children's hospitals for a suspected bTRAIN (receipt of respiratory culture plus ≥1 doses of an antibiotic within 48 h). The primary predictor was respiratory culture growth categorized as Pseudomonas aeruginosa, P. aeruginosa + ≥1 other bacterium, other bacteria alone, or normal flora/no growth. Our primary outcome was bTRAIN treatment with a complete course of antibiotics as documented by the discharge team. We used logistic regression with generalized estimating equations to identify the association between our primary predictor and outcome and to identify demographic, clinical, and diagnostic testing factors associated with treatment. RESULTS: Of the 440 admissions among 289 patients meeting inclusion criteria, 307 (69.8%) had positive respiratory culture growth. Overall, 237 (53.9%) of admissions resulted in bTRAIN treatment. Relative to a negative culture, a culture positive for P. aeruginosa plus ≥1 other organism (adjusted odds ratio [aOR] 2.3; 95% confidence interval [CI] 1.02-5.0)] or ≥1 other organism alone (aOR: 2.8; 95% CI: 1.4-5.6)] was associated with treatment. Several clinical and diagnostic testing (respiratory Gram-stain and chest radiograph) findings were also associated with treatment. Positive respiratory viral testing was associated with reduced odds of treatment (aOR: 0.5; 95% CI: 0.2-0.9). CONCLUSIONS: Positive respiratory cultures as well as clinical indicators of acute illness and nonculture test results were associated with bTRAIN treatment. Clinicians may be more comfortable withholding antibiotics when a virus is identified during testing.

Perspectives and Behaviors of People with Diabetes toward Time in Range and Glucose Control in Diabetes Management: An Online Survey.

INTRODUCTION: This study assessed experiences, attitudes, and behaviors of people with diabetes (PwD) regarding diabetes self-management and glucose control, and their level of awareness, knowledge, and attitudes toward time in range (TIR). METHODS: This quantitative survey was conducted using an online questionnaire across seven countries. Respondents were PwD classified into three subgroups: type 1 (T1), type 2 insulin (T2 insulin), and type 2 not on insulin (T2 N/insulin). RESULTS: Respondents included 621 people in the T1, 780 people in the T2 insulin, and 735 people in the T2 N/insulin subgroups. Awareness of TIR was low, particularly in the T2 N/insulin subgroup (T1 53%, T2 insulin 29%, T2 N/insulin 9%). Despite a lower current use of continuous glucose monitoring (CGM) among the T2 insulin and T2 N/insulin participants (38% and 9%, respectively), versus T1 participants (64%), most (> 70%) were positive toward utilizing new tools and measures to self-manage blood glucose. Recommendations from their healthcare professionals (HCPs) were cited as a strong motivator to try new measures for analyzing glucose levels. The main barriers cited were limited access to CGM and lack of understanding of TIR benefits. Cost was the main reason given by ≥ 40% of respondents for stopping CGM use. CONCLUSIONS: There is an unmet need in diabetes management, and TIR and CGM offer a potential solution. PwD are motivated to manage their blood glucose levels and are positive toward utilizing new tools and measures to achieve this goal. HCPs play a pivotal role in informing and guiding PwD on new measures for analyzing glucose.

Restricted Cusp Motion in Newly Implanted Tricuspid Bioprostheses: Incidence, Predictors, and Impact on Survival.

OBJECTIVE: This study aimed to investigate the occurrence of restricted cusp motion (RCM) at the time of bioprosthetic tricuspid valve replacement (TVR) and analyzed associated risk factors and outcomes. METHODS: This study involved adult patients who underwent TVR with a bioprosthesis at our institution between 2012 and 2022. Bioprosthetic cusp motion was analyzed de-novo through a detailed review of intraoperative transesophageal echocardiograms (TEE). Two models of porcine valves were implanted, the Hancock II bioprosthesis (Medtronic, Inc, Minneapolis, Minnesota) and the St. Jude Epic bioprosthesis (St. Jude Medical, St. Paul, Minnesota). RESULTS: Among the 476 patients who met the inclusion criteria, RCM was identified on the immediate post-bypass TEE in 150 (31.5%); there was complete immobility of the cusp in 63 patients (13.2%) and limited movement of a cusp in 87 patients (18.3%). In a multivariable logistic regression analysis, the Hancock II model (OR 6.15, p<0.001), a larger orifice area (per IQR increase, OR 1.58, p=0.017), a smaller body surface area (per IQR increase, OR 0.68, p=0.040), and a lower ejection fraction (per IQR increase, OR 0.60, p=0.033) were independently associated with having RCM. Cox regression adjusting for 15 covariates revealed that RCM at time of TVR was independently associated with an increased risk of mortality (HR 1.35, p=0.049). CONCLUSIONS: This study revealed a high incidence of restricted cusp motion in bioprosthetic valves in the tricuspid position detected shortly post-implantation, which was associated with increased late mortality. To reduce the probability of restricted cusp motion, it is important to select the appropriate prosthesis model and size, particularly in small patients.

Persistent Luminescence Nanosensors: A Generalized Optode-Based Platform for Autofluorescence-Free Sensing in Biological Systems.

Fluorescent nanosensors have revolutionized diagnostics and our ability to monitor cellular dynamics. Yet, distinguishing sensor signals from autofluorescence remains a challenge. Here, we merged optode-based sensing with near-infrared-emitting ZnGa2O4:Cr3+ persistent luminescence nanoparticles (PLNPs) to create nanocomposites for autofluorescence-free "glow-in-the-dark" sensing. Hydrophobic modification and incorporation of the persistent luminescence nanoparticles into an optode-based nanoparticle core yielded persistent luminescence nanosensors (PLNs) for five analytes (K+, Na+, Ca2+, pH, and O2) via two distinct mechanisms. We demonstrated the viability of the PLNs by quantifying K+ in fetal bovine serum, calibrating the pH PLNs in the same, and ratiometrically monitoring O2 metabolism in cultures of Saccharomyces cerevisiae, all the while overcoming their respective autofluorescence signatures. This highly modular platform allows for facile tuning of the sensing functionality, optical properties, and surface chemistry and promises high signal-to-noise ratios in complex optical environments.

Conventional versus minimally invasive extra-corporeal circulation in patients undergoing cardiac surgery: A randomized controlled trial (COMICS).

INTRODUCTION: The trial hypothesized that minimally invasive extra-corporeal circulation (MiECC) reduces the risk of serious adverse events (SAEs) after cardiac surgery operations requiring extra-corporeal circulation without circulatory arrest. METHODS: This is a multicentre, international randomized controlled trial across fourteen cardiac surgery centres including patients aged ≥18 and <85 years undergoing elective or urgent isolated coronary artery bypass grafting (CABG), isolated aortic valve replacement (AVR) surgery, or CABG + AVR surgery. Participants were randomized to MiECC or conventional extra-corporeal circulation (CECC), stratified by centre and operation. The primary outcome was a composite of 12 post-operative SAEs up to 30 days after surgery, the risk of which MiECC was hypothesized to reduce. Secondary outcomes comprised: other SAEs; all-cause mortality; transfusion of blood products; time to discharge from intensive care and hospital; health-related quality-of-life. Analyses were performed on a modified intention-to-treat basis. RESULTS: The trial terminated early due to the COVID-19 pandemic; 1071 participants (896 isolated CABG, 97 isolated AVR, 69 CABG + AVR) with median age 66 years and median EuroSCORE II 1.24 were randomized (535 to MiECC, 536 to CECC). Twenty-six participants withdrew after randomization, 22 before and four after intervention. Fifty of 517 (9.7%) randomized to MiECC and 69/522 (13.2%) randomized to CECC group experienced the primary outcome (risk ratio = 0.732, 95% confidence interval (95% CI) = 0.556 to 0.962, p = 0.025). The risk of any SAE not contributing to the primary outcome was similarly reduced (risk ratio = 0.791, 95% CI 0.530 to 1.179, p = 0.250). CONCLUSIONS: MiECC reduces the relative risk of primary outcome events by about 25%. The risk of other SAEs was similarly reduced. Because the trial terminated early without achieving the target sample size, these potential benefits of MiECC are uncertain.

Select Minor Cannabinoids from Cannabis sativa are Cannabimimetic and Antinociceptive in a Mouse Model of Chronic Neuropathic Pain.

Chronic pain conditions affect nearly 20% of the population in the United States. Current medical interventions, such as opioid drugs, are effective at relieving pain but are accompanied by many undesirable side effects. This is one reason increased numbers of chronic pain patients have been turning to Cannabis for pain management. Cannabis contains many bioactive chemical compounds; however, current research looking into lesser-studied minor cannabinoids in Cannabis lacks uniformity between experimental groups and/or excludes female mice from investigation. This makes it challenging to draw conclusions between experiments done with different minor cannabinoid compounds between labs or parse out potential sex differences that could be present. We chose five minor cannabinoids found in lower quantities within Cannabis: cannabinol (CBN), cannabidivarin (CBDV), cannabigerol (CBG), Δ8-tetrahydrocannabinol (Δ8-THC), and Δ9-tetrahydrocannabivarin (THCV). These compounds were then tested for their cannabimimetic and pain-relieving behaviors in a cannabinoid tetrad assay and a chemotherapy-induced peripheral neuropathy (CIPN) pain model in male and female CD-1 mice. We found that the minor cannabinoids we tested differed in the cannabimimetic behaviors evoked, as well as the extent. We found that CBN, CBG, and high dose Δ8-THC evoked some tetrad behaviors in both sexes, while THCV and low dose Δ8-THC exhibited cannabimimetic tetrad behaviors only in females. Only CBN efficaciously relieved CIPN pain, which contrasts with reports from other researchers. Together these findings provide further clarity to the pharmacology of minor cannabinoids and suggest further investigation into their mechanism and therapeutic potential. Significance Statement Minor cannabinoids are poorly studied ligands present in lower levels in Cannabis than cannabinoids like THC. In this study we evaluated 5 minor cannabinoids (CBN, CBDV, CBG, THCV, and Δ8-THC) for their cannabimimetic and analgesic effects in mice. We found that 4 of the 5 minor cannabinoids showed cannabimimetic activity, while one was efficacious in relieving chronic neuropathic pain. This work is important in further evaluating the activity of these drugs, which are seeing wider public use with marijuana legalization.

An update of the development of motor behavior.

This primer describes research on the development of motor behavior. We focus on infancy when basic action systems are acquired-posture, locomotion, manual actions, and facial actions-and we adopt a developmental systems perspective to understand the causes and consequences of developmental change. Experience facilitates improvements in motor behavior and infants accumulate immense amounts of varied everyday experience with all the basic action systems. At every point in development, perception guides behavior by providing feedback about the results of just prior movements and information about what to do next. Across development, new motor behaviors provide new inputs for perception. Thus, motor development opens up new opportunities for acquiring knowledge and acting on the world, instigating cascades of developmental changes in perceptual, cognitive, and social domains. This article is categorized under: Cognitive Biology > Cognitive Development Psychology > Motor Skill and Performance Neuroscience > Development.

Interventions to Prevent Falls in Community-Dwelling Older Adults: US Preventive Services Task Force Recommendation Statement.

Importance: Falls are the leading cause of injury-related morbidity and mortality among older adults in the US. In 2018, 27.5% of community-dwelling adults 65 years or older reported at least 1 fall in the past year and 10.2% reported a fall-related injury. In 2021, an estimated 38 742 deaths resulted from fall-related injuries. Objective: The US Preventive Services Task Force (USPSTF) commissioned a systematic review to evaluate the effectiveness and harms of primary care-relevant interventions to prevent falls and fall-related morbidity and mortality in community-dwelling adults 65 years or older. Population: Community-dwelling adults 65 years or older at increased risk of falls. Evidence Assessment: The USPSTF concludes with moderate certainty that exercise interventions provide a moderate net benefit in preventing falls and fall-related morbidity in older adults at increased risk for falls. The USPSTF concludes with moderate certainty that multifactorial interventions provide a small net benefit in preventing falls and fall-related morbidity in older adults at increased risk for falls. Recommendation: The USPSTF recommends exercise interventions to prevent falls in community-dwelling adults 65 years or older who are at increased risk for falls. (B recommendation) The USPSTF recommends that clinicians individualize the decision to offer multifactorial interventions to prevent falls to community-dwelling adults 65 years or older who are at increased risk for falls. Existing evidence indicates that the overall net benefit of routinely offering multifactorial interventions to prevent falls is small. When determining whether this service is appropriate for an individual, patients and clinicians should consider the balance of benefits and harms based on the circumstances of prior falls, presence of comorbid medical conditions, and the patient's values and preferences. (C recommendation).

Implementation of an Enhanced Recovery After Surgery Protocol for Cranial Vault Remodeling Procedures.

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols have been implemented across surgical disciplines, including cranial vault remodeling for craniosynostosis. The authors aim to describe the implementation of an ERAS protocol for cranial vault remodeling procedures performed for patients with craniosynostosis at a tertiary care hospital. DESCRIPTION: Institutional review board approval was received. All patients undergoing a cranial remodeling procedure for craniosynostosis at the authors' institution over a 10-year period were collected (n = 168). Patient and craniosynostosis demographics were collected as well as operative details. Primary outcome measures were intensive care unit length of stay (ICU LOS) and narcotic usage. Chi squared and independent t-tests were employed to determine significance. A significance value of 0.05 was utilized. RESULTS: During the time examined, there were 168 primary cranial vault remodeling procedures performed at the authors' institution - all of which were included in the analysis. Use of the ERAS protocol was associated with decreased initial 24-hour morphine equivalent usage (p < 0.01) and decreased total morphine equivalent usage (p < 0.01). Patients using the ERAS protocol experienced a shorter ICU LOS (p < 0.01), but the total hospital length of stay was unchanged. CONCLUSION: This study reiterates the benefit of developing and implementing an ERAS protocol for patients undergoing cranial vault remodeling procedures. The protocol resulted in an overall decreased ICU LOS and a decrease in narcotic use. This has implications for ways to maximize hospital reimbursement for these procedures, as well as potentially improve outcomes.

Long-term follow-up of patients with intermediate-risk neuroblastoma treated with response- and biology-based therapy: A report from the Children's Oncology Group study ANBL0531.

BACKGROUND: We previously reported excellent three-year overall survival (OS) for patients with newly diagnosed intermediate-risk neuroblastoma treated with a biology- and response-based algorithm on the Children's Oncology Group study ANBL0531. We now present the long-term follow-up results. METHODS: All patients who met the age, stage, and tumor biology criteria for intermediate-risk neuroblastoma were eligible. Treatment was based on prognostic biomarkers and overall response. Event-free survival (EFS) and OS were estimated by the Kaplan-Meier method. RESULTS: The 10-year EFS and OS for the entire study cohort (n = 404) were 82.0% (95% confidence interval (CI), 77.2%-86.9%) and 94.7% (95% CI, 91.8%-97.5%), respectively. International Neuroblastoma Staging System stage 4 patients (n = 133) had inferior OS compared with non-stage 4 patients (n = 271; 10-year OS: 90.8% [95% CI, 84.5%-97.0%] vs 96.6% [95% CI, 93.9%-99.4%], p = .02). Infants with stage 4 tumors with ≥1 unfavorable biological feature (n = 47) had inferior EFS compared with those with favorable biology (n = 61; 10-year EFS: 66.8% [95% CI, 50.4%-83.3%] vs 86.9% [95% CI, 76.0%-97.8%], p = .02); OS did not differ (10-year OS: 84.4% [95% CI, 71.8%-97.0%] vs 95.0% [95% CI, 87.7%-100.0%], p = .08). Inferior EFS but not OS was observed among patients with tumors with (n = 26) versus without (n = 314) 11q loss of heterozygosity (10-year EFS: 68.4% [95% CI, 44.5%-92.2%] vs 83.9% [95% CI, 78.7%-89.2%], p = .03; 10-year OS: 88.0% [95% CI, 72.0%-100.0%] vs 95.7% [95% CI, 92.8%-98.6%], p = .09). CONCLUSIONS: The ANBL0531 trial treatment algorithm resulted in excellent long-term survival. More effective treatments are needed for subsets of patients with unfavorable biology tumors.

Reimagining general surgery resident selection: Collaborative innovation through design thinking.

Introduction: The process by which surgery residency programs select applicants is complex, opaque, and susceptible to bias. Despite attempts by program directors and educational researchers to address these issues, residents have limited ability to affect change within the process at present. Here, we present the results of a design thinking brainstorm to improve resident selection and propose this technique as a framework for surgical residents to creatively solve problems and generate actionable changes. Methods: Members of the Collaboration of Surgical Education Fellows (CoSEF) used the design thinking framework to brainstorm ways to improve the resident selection process. Members participated in one virtual focus group focused on identifying pain points and developing divergent solutions to those pain points. Pain points and solutions were subsequently organized into themes. Finally, members participated in a second virtual focus group to design prototypes to test the proposed solutions. Results: Sixteen CoSEF members participated in one or both focus groups. Participants identified twelve pain points and 57 potential solutions. Pain points and solutions were grouped into the three themes of transparency, fairness, and applicant experience. Members subsequently developed five prototype ideas that could be rapidly developed and tested to improve resident selection. Conclusions: The design thinking framework can help surgical residents come up with creative ideas to improve pain points within surgical training. Furthermore, this framework can supplement existing quantitative and qualitative methods within surgical education research. Future work will be needed to implement the prototypes devised during our sessions and turn them into complete interventions. Key message: In this paper, we demonstrate the results of a resident-led design thinking brainstorm on improving resident selection in which our team identified twelve pain points in resident selection, ideated 57 solutions, and developed five prototypes for further testing. In addition to sharing our results, we believe design thinking can be a useful framework for creative problem solving within surgical education.
