Obesity is associated with hyperandrogenemia in a nationally-representative sample of U.S. girls aged 6–18 years

Abstract Context Studies have associated obesity with peri-pubertal hyperandrogenemia. However, these studies were performed in academic centers and could have been influenced by selection bias. Objective To investigate if free testosterone levels are elevated in peri-pubertal girls with obesity. Design/Setting We analyzed data from the National Health and Nutrition Examination Survey (NHANES) 2013–2016 databases. Participants 1,299 girls aged 6–18 years residing in U.S. Main Outcome Measures Mean free testosterone concentration (calculated from total testosterone and sex hormone-binding globulin). Results Among girls aged 6–9 years, mean (95% CI) free testosterone was 0.33 pg/ml (0.28–0.38) in healthy weight girls vs. 0.86 pg/ml (0.67–1.05) in girls with obesity. Among girls aged 10–14 years, free testosterone was 2.29 pg/ml (2.05–2.53) in healthy weight girls vs. 4.10 pg/ml (3.60–4.60) in girls with obesity. Among girls aged 15–18 years, free testosterone was 3.33 pg/ml (2.96–3.70) in healthy weight girls and 5.64 pg/ml (4.93–6.36) in girls with obesity. Girls with obesity in all age groups had higher free testosterone levels compared to healthy weight girls. In each age group, the 95% CIs for free testosterone did not overlap between healthy weight vs. obesity subgroups. A multiple regression model accounted for 42% of the variance in free testosterone (R2=0.42), and both weight and age categories were independent predictors of free testosterone (p<0.0001 for each). Conclusion In a nationally-representative sample of U.S. girls, obesity is associated with elevated free testosterone, suggesting an important relationship between obesity and peri-pubertal hyperandrogenemia.

Return to Work Following Anterior Lumbar Interbody Fusion with Percutaneous Posterior Pedicle Fixation: A Retrospective Analysis from Two Academic Centers in Germany.

Objective: Return to work after spinal surgery is a crucial factor in the recovery process. It can contribute not only to physical rehabilitation but also to psychological well-being. This study aims to evaluate the rate of return to work following elective lumbar spine surgery and identify predictors that predict failure of return to work. Methods: Adult patients who underwent anterior lumbar interbody fusion at two medical centers were retrospectively identified. A standardized telephone interview was conducted for the final analysis to assess the clinical outcomes of these patients. Results: Out of a total of 159 patients, 104 were of working age at the time of the elective surgery. Data were missing for 35 patients, who were thus excluded from the analysis. All patients had a minimum follow-up period of one year. After surgery, 75% of the patients returned to work within a median time of 3 months. Quality of life, back pain, leg pain, and ODI scores, as well as self-reported satisfaction, were significantly better in patients who returned to work (p < 0.05). Tobacco use and previous musculoskeletal surgery were significant predictive factors of failure to return to work. None of the patients who were unemployed prior to surgery returned to work. Conclusions: Our study reveals that 75% of patients returned to work within three months after surgery. The most significant predictor of failure to return to work is being unemployed before surgery. Additionally, preoperative education about postoperative behavior and physical activity could potentially increase the rate.

Bone Accrual Trajectories in Children and Adolescents with Perinatal HIV Infection.

Low bone mineral density (BMD) has been reported in children and adolescents living with perinatally-acquired HIV (PHIV). Little is known about their bone accrual through puberty compared to an uninfected healthy cohort. To compare bone accrual in PHIV and healthy children. PHIV children aged 7-16 years had dual energy X-ray absorptiometry (DXA) at entry, 2 years, and then at least 2 years later. Bone accrual was compared to healthy children from the Bone Mineral Density in Childhood Study (BMDCS). United States academic clinical research centers. 172 PHIV; 1321 BMDCS. We calculated height-adjusted whole-body and spine BMD and bone mineral content (BMC) Z-scores in PHIV using BMDCS reference curves. We fit piecewise weighted linear mixed effects models with change points at 11 and 15 years, adjusted for age, sex, race, height Z-score, and Tanner stage, to compare BMD and BMC Z-scores across actual age by cohort.Main Outcome Measure: BMD/BMC Z-scores. Height-adjusted whole-body BMD and BMC Z-scores in PHIV were lower across age compared to BMDCS children. Spine BMD Z-score across age was higher in PHIV after height adjustment. Whole-body and spine bone area tended to be lower in PHIV. PHIV had slower accrual in whole-body and spine bone area before 14 years. After 15 years, bone area accruals were similar, as were height-adjusted spine BMC Z-scores, across age. PHIV had persistent deficits in all measures except height-adjusted spine BMD and BMC Z-scores. Data are needed on PHIV followed to adulthood.

Thrombectomy for Stroke With Large Infarct on Noncontrast CT

Recent large infarct thrombectomy trials used heterogeneous imaging modalities and time windows for patient selection. Noncontrast computed tomographic (CT) scan is the most common stroke imaging approach. It remains uncertain whether thrombectomy is effective for patients with large infarcts identified using noncontrast CT alone within 24 hours of stroke onset. To evaluate the effect of thrombectomy in patients with a large infarct on a noncontrast CT scan within 24 hours of onset. Open-label, blinded-end point, bayesian-adaptive randomized trial with interim analyses for early stopping (futility or success) or population enrichment, which was conducted at 47 US academic and community-based stroke thrombectomy centers. Three hundred patients presenting within 24 hours with anterior-circulation, large-vessel occlusion and large infarct on noncontrast CT scan, with Alberta Stroke Program Early CT Scores of 2 to 5, were randomized to undergo thrombectomy or usual care. Enrollment occurred July 16, 2019 to October 17, 2022; final follow-up, January 25, 2023. The intervention patients (n = 152) underwent endovascular treatment using standard thrombectomy devices and usual medical care. Control patients (n = 148) underwent usual medical care alone. The primary efficacy end point was improvement in 90-day functional outcome measured using mean utility-weighted modified Rankin Scale (UW-mRS) scores (range, 0 [death or severe disability] to 10 [no symptoms]; minimum clinically important difference, 0.3). A bayesian model determined the posterior probability that the intervention would be superior to usual care; statistical significance was a 1-sided posterior probability of .975 or more. The primary adverse event end point was 90-day mortality; secondary adverse event end points included symptomatic intracranial hemorrhage and radiographic intracranial hemorrhage. The trial enrolled 300 patients (152 intervention, 148 control; 138 females [46%]; median age, 67 years), without early stopping or enrichment; 297 patients completed the 90-day follow-up. The mean (SD) 90-day UW-mRS score was 2.93 (3.39) for the intervention group vs 2.27 (2.98) for the control group with an adjusted difference of 0.63 (95% credible interval [CrI], -0.09 to 1.34; posterior probability for superiority of thrombectomy, .96). The 90-day mortality was similar between groups: 35.3% (53 of 150) for the intervention group vs 33.3% (49 of 147) for the control group. Six of 151 patients (4.0%) in the intervention group and 2 of 149 (1.3%) in the control group experienced 24-hour symptomatic intracranial hemorrhage. Fourteen patients of 148 (9.5%) in the intervention group vs 4 of 146 (2.7%) in the control group experienced parenchymal hematoma type 1 hemorrhages; 14 (9.5%) in the intervention group vs 5 (3.4%) in the control group experienced parenchymal hematoma type 2 hemorrhages; and 24 (16.2%) in the intervention group vs 9 (6.2%) in the control group experienced subarachnoid hemorrhages. Among patients with a large infarct on noncontrast CT within 24 hours, thrombectomy did not demonstrate improvement in functional outcomes. But the width of the credible interval around the effect estimate includes the possibility of both no important effect and a clinically relevant benefit, so the potential role of thrombectomy with this imaging approach and time window will likely require additional study.

Lower Perceived Social Support During Hospitalization by Close Family Members may have Significant Associations with Psychological Distress 1 Month After Cardiac Arrest.

The perception of having poor social support is associated with worse symptoms of psychological distress in close family members of critically ill patients, yet this has never been tested after cardiac arrest. Close family members of consecutive patients with cardiac arrest hospitalized at an academic tertiary care center participated in a prospective study. The validated Multidimensional Scale of Perceived Social Support (MSPSS) cued to index hospitalization was administered before discharge. Multivariate linear regressions estimated the associations between the total MSPSS score and total scores on the Patient Health Questionnaire-8 (PHQ-8), Generalized Anxiety Disorder 2-item (GAD-2), and the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), assessed 1month after cardiac arrest. In 102 participants (mean age 52 ± 15years, 70% female, 21% Black, 33% Hispanic) with complete data, the prevalence of depression, generalized anxiety, and probable posttraumatic stress disorder at a median duration of 28.5days (interquartile range 10-63days) from cardiac arrest was 61%, 34%, and 13%, respectively. A lower MSPSS score was significantly associated with higher PHQ-8 scores (β = - 0.11 [95% confidence interval - 0.04 to - 0.18]; p < 0.01), even after adjusting for family members' age, sex, prior psychiatric condition, and witnessing of cardiopulmonary resuscitation and patient's discharge disposition (β = - 0.11 [95% confidence interval - 0.02 to - 0.15]; p < 0.01). Similarly, significant inverse associations of total MSPSS scores were seen with 1-month GAD-2 and PCL-5 scores. Poor social support during hospitalization, as perceived by close family members of cardiac arrest survivors, is associated with worse depressive symptoms at 1month. Temporal changes in social networks and psychological distress warrant further investigation.

Abstract B132: Access to palliative care for individuals with cancer experiencing homelessness

Abstract Introduction Persons experiencing homelessness (PEH) face significant disparities in health outcomes and access to healthcare, including cancer-related and end-of-life care. PEH are less likely to receive age-appropriate cancer screening, more likely to be diagnosed with cancer at later stages, and more likely to die secondary to cancer compared to the general population. Qualitative research has demonstrated that PEH and the providers who care for them perceive gaps in access to palliative care, largely due to a lack of palliative care programs that cater to the specific needs of PEH. However, less is known about how medical providers’ referral patterns affect access to care. Providers may be less likely to refer PEH to palliative care services because of these known gaps in access, exacerbating existing disparities. The purpose of this study was to quantify the rates of palliative care referrals and outpatient palliative care visits along with time to initial palliative care referral and ambulatory palliative care visit. We hypothesized that PEH would be referred to palliative care at lower rates and have longer intervals to palliative care follow-up as compared to their housed counterparts. Methods A retrospective analysis was performed on patients with cancer admitted to an academic center’s medical oncology service between July 2022 and June 2023. Patients were stratified into two groups based on their housing status: housed and PEH. A comparative quantitative analysis was conducted between these groups. Results 1166 patients with cancer were admitted to the medical oncology service during the one-year study period. The mean age of the cohort was 61.0 years and 46.7% were female. Seventeen (1.4%) PEH and 1149 (98.6%) patients who were housed were identified. Among PEH, five (29.4%) were referred to ambulatory palliative care or received an inpatient consult to palliative care. Among patients who were housed, 362 (31.5%) were referred to ambulatory palliative care or received an inpatient consult to palliative care. Two (11.8%) PEH attended an ambulatory palliative care appointment compared to 183 (15.9%) patients who were housed. The mean number of days to first palliative care or hospice referral/consult was 25.5 in PEH and 43.9 in patients who were housed. The mean number of days to first ambulatory palliative care visit was 131 in PEH and 83.7 in patients who were housed. Conclusion The frequency of inpatient and ambulatory palliative care referrals was comparable between the two groups, suggesting that PEH are appropriately referred to palliative care. However, PEH had longer intervals from cancer diagnosis to first outpatient palliative care visit, suggesting that additional supports may be needed to ensure PEH can access outpatient follow-up. While this quantitative study is underpowered to detect statistically significant differences, it highlights a potential area for further study to develop interventions to better support PEH to achieve timely follow-up with ambulatory palliative care and hospice services after referral.

Barriers to Offering Organ Preservation for Rectal Cancer in a Predominantly Hispanic Safety Net Hospital.

Total neoadjuvant therapy (TNT) for locally advanced rectal cancer (LARC) has shown promise in achieving pathologic complete response (pCR) and enabling organ preservation through watch-and-wait (WW) strategies. However, implementation of WW protocols in diverse patient populations and safety-net hospitals faces unique challenges. The objective of this study is to evaluate TNT outcomes and identify barriers to WW implementation in a predominantly Hispanic safety-net hospital in South Texas. A retrospective review was conducted of 40 LARC patients treated with TNT at an academic tertiary referral center in South Texas between 2018 and 2023. Patient demographics, disease characteristics, and pCR rates were analyzed. A survey of multidisciplinary providers assessed perceived institutional and patient-related barriers to WW implementation. The cohort was 70% Hispanic, with a median age of 54 years. Most patients had advanced disease at diagnosis (57.5% T4, 65% N2). The pCR rate was 18.5% (5/27) among patients undergoing surgery. Re-review of MRIs for pCR patients revealed that 2/5 had minimal residual disease. The provider survey identified MRI quality variability, lack of dedicated treatment coordinators, and concerns about patient compliance and financial barriers as key obstacles to WW implementation. Despite advanced disease presentation in a predominantly Hispanic population, TNT achieved pCR rates comparable to international trials. Institutional and patient-level barriers to WW were identified, informing the development of a tailored WW protocol for this unique patient population.

“Prepectoral tissue expanders without mesh as a bridge to delayed autologous breast reconstruction: Experience at a single academic center”

Acellular dermal matrix (ADM) is a useful adjunct in implant-based breast reconstruction. The benefits of using ADM with an expander as a temporary bridge to delayed autologous reconstruction are unknown. Placing prepectoral tissue expanders, without ADM, as a bridge to delayed autologous reconstruction could yield cost savings, shorten operating time and decrease complications. This investigation seeks to demonstrate the safety of placing prepectoral tissue expanders without ADM at the time of mastectomy as the first stage of autologous breast reconstruction. A retrospective, chart review was performed at our major academic institution between 2015 and 2020. Included were female patients, 18 years or older at the time of reconstruction, who underwent mastectomy with prepectoral tissue expander placement followed by autologous breast reconstruction at a delayed second stage. Excluded were patients of male gender, younger than 18, patients with lumpectomy only, subpectoral reconstruction, or immediate autologous reconstruction. Data on ADM, patient demographics, comorbidities, and cancer treatment were collected. There were 189 reconstructed breasts of which 56 (29.6 %) used ADM, 131 (69.3 %) did not use ADM, and 2 patients (1.1 %) of unknown ADM use. Expanders were in place for a mean time of 8.9±6.2 months. There was no statistically significant difference in complication rates between the ADM and no-ADM groups. Therefore, not wrapping prepectoral tissue expanders in ADM, at the time of mastectomy, has an equivalent rate of complications compared to ADM wrapping among patients who go on to have second stage autologous breast reconstruction.

Impact of patient safety bundle and team-based training on obstetric hypertensive emergencies.

Hypertensive disorders of pregnancy, defined as chronic (<20 weeks) or gestational (>20 weeks), are a leading cause of pregnancy related mortality in the United States1. Hypertensive disorders of pregnancy had increased prevalence from 13.3% to 15.9% among delivery hospitalizations between 2017 and 20191. The objective of this project was to increase the percentage of obstetric patients with hypertensive emergency who received evidence-based treatment within 60 minutes at a single academic center. Study Design Data was collected before and after the implementation of a hypertension patient safety bundle. Each occurrence of hypertensive emergency was assessed to determine if evidence-based intervention occurred within 60 minutes, and if the intervention steps were successfully followed. Bundle implementation included creation of a standardized order set and interdisciplinary team-based simulations. Baseline data compared 250 pre-implementation to 250 post-implementation interventions. The quality improvement interdisciplinary team reevaluated data monthly and incorporated process improvements through Plan Do Study Act (PDSA) cycles to achieve a goal of 80% of patients receiving evidence-based treatment within 60 minutes. Results A total of 1025 hypertensive emergencies were identified in 543 patients. Prior to the protocol on average 64% of patients received evidence-based, timely treatment. After implementation of this bundle and several PDSA cycles, we sustained >80% of patients receiving target treatment for the final six months of data collection. The leading deviations were "no medication given" and "incorrect medication". Improvements in order set accessibility and repeated team-based trainings led to improvement in these identified protocol deviations. Conclusion Implementation of a patient safety bundle led to a sustained 6 month improvement in the percentage of patients receiving appropriate treatment of obstetric hypertensive emergency within 60 minutes of the first severe hypertension measurement. Processes that may have helped achieve this outcome included standardized order sets, team awareness of institutional data and team-based simulations.

What Is Culture Made of? An Exploratory Study of Ethical Cultures and Provider Perspectives on the Care of Periviable Neonates

Objective Studies examining intercenter variation in neonatal intensive care unit practices at the limits of fetal viability have hypothesized that institutional “culture” can be one of many factors that impact patient care. This study aimed to describe institutional culture at a single, large academic center with regard to the antenatal consultation, resuscitation, and postnatal management of periviable neonates. Study Design Members of six clinical groups—attending and fellow maternal–fetal medicine physicians, attending and fellow neonatal–perinatal medicine physicians, neonatal nurses, advanced practiced neonatal nurses, pediatric hospitalist physicians, and neonatal respiratory therapists—were invited to complete qualitative, semi-structured interviews. All audio recordings were transcribed. Dedoose software was used to complete team-based coding and thematic analysis. Results Twenty-two interviews were completed. Thematic analysis revealed three central themes described by participants as contributory to institutional culture: Perception, referring to factors based on individual attitudes and insights, Statements of Information, referring to factors anchored in more objective concepts such as outcomes data and institutional policy, and Dynamic Factors, referring to the relatively fluid factors of institutional culture that interact with both Perception and Statements of Information. Participants were more likely to mention factors in the Perception category (n = 430) compared with factors in the Information category (n = 225), and although the latter were described as critical components of antenatal counseling and perinatal management, the philosophy of our unit appeared to be more heavily rooted in institutional memory and individual belief systems. Conclusion Our data demonstrate a personal undertone to institutional culture at the limits of viability, with an emphasis on individual attitudes and subjective interpretations of fact rather than empirical data. As the landscape of neonatology continues to change, understanding those factors that contribute to culture remains a necessary step toward deconstructing institutional belief systems and optimizing clinical care. Key Points

Environmentally sustainable opportunities for health systems: Metered-dose inhaler prescribing, dispensing, use and waste at a tertiary academic centre

Background: The Canadian health sector’s carbon footprint is among the highest in the world and is responsible for 4.6% of Canada’s total greenhouse gas emissions, a quarter of which is linked to pharmaceuticals, with metered-dose inhalers (MDIs) contributing disproportionally high amounts. Objectives: To describe MDI prescribing, dispensing, use and waste patterns at a Canadian tertiary care academic hospital. Methods: In a retrospective point-prevalence cohort study, 100 consecutive patients discharged from medical and surgical services who were prescribed at least 1 MDI during their admission were included. Data were collected to describe patient demographics, MDI prescribing, dispensing, use and waste patterns. Use and waste data were applied to annual purchasing data to estimate annual usage and waste. Financial cost was computed using local purchasing estimates and carbon cost was calculated using published estimates. Results: In 100 consecutively discharged patients, 315 MDIs were dispensed in total, of which 96 were unused. This represents 61,440 actuations dispensed, with 56,773 (92%) of doses unused or wasted. Waste data were applied to annual estimates, with a calculated annual carbon footprint of 315.8 tons of carbon dioxide equivalent (tCO2e). We estimate that a 20% waste reduction would result in carbon savings of 68.5 tCO2e. If 20% of salbutamol prescriptions were switched to the dry powder inhaler alternative, terbutaline, a 14% reduction in waste would be required to offset the additional monetary cost. Conclusions: This study suggests that 92% of MDI doses are unused and wasted. Opportunities for waste reduction exist and would be associated with both financial and carbon savings.

The Subcutaneous Adipose Microenvironment as a Determinant of Body Fat Development in Polycystic Ovary Syndrome.

Adipose steroid metabolism modifies body fat development in polycystic ovary syndrome (PCOS). To determine whether subcutaneous (SC) abdominal adipose aldo-keto reductase 1C3 (AKR1C3; a marker of testosterone generation) is increased in normal-weight women with PCOS vs age- and body mass index (BMI)-matched normoandrogenic ovulatory women (controls) and is related to SC abdominal adipose activator protein-1 (AP-1; a marker of adipocyte differentiation) and/or androgen receptor (AR) protein expression in predicting fat accretion. Prospective cohort study. Academic center. Eighteen normal-weight PCOS women; 17 age- and BMI-matched controls. Circulating hormone/metabolic determinations, intravenous glucose tolerance testing, total body dual-energy x-ray absorptiometry, SC abdominal fat biopsy, immunohistochemistry. Clinical characteristics, hormonal concentrations, body fat distribution, SC adipose AKR1C3, AR, and AP-1 protein expression. Women with PCOS had significantly higher serum androgen levels and greater android/gynoid fat mass ratios than controls. SC adipose AKR1C3, AR, and AP-1 protein expressions were comparable between the study groups, but groups differed in correlations. In PCOS women vs controls, SC adipose AKR1C3 protein expression correlated positively with android and gynoid fat masses and negatively with SC adipose AP-1 protein expression. SC adipose AR protein expression correlated negatively with fasting serum free fatty acid and high-density lipoprotein levels. In both study groups, SC adipose AKR1C3 protein expression negatively correlated with serum cortisol levels. In normal-weight PCOS women, SC abdominal adipose AKR1C3 protein expression, in combination with intra-adipose AP-1 and AR-dependent events, predicts fat accretion in the presence of physiological cortisol levels.

Methotrexate and Tumor Necrosis Factor Inhibitors Independently Decrease Neutralizing Antibodies after SARS-CoV-2 Vaccination: Updated Results from the SUCCEED Study.

Objective: SARS-CoV-2 remains the third most common cause of death in North America. We studied the effects of methotrexate and tumor necrosis factor inhibitor (TNFi) on neutralization responses after COVID-19 vaccination in immune-mediated inflammatory disease (IMID). Methods: Prospective data and sera of adults with inflammatory bowel disease (IBD), rheumatoid arthritis (RA), spondyloarthritis (SpA), psoriatic arthritis (PsA), and systemic lupus (SLE) were collected at six academic centers in Alberta, Manitoba, Ontario, and Quebec between 2022 and 2023. Sera from two time points were evaluated for each subject. Neutralization studies were divided between five laboratories, and each lab's results were analyzed separately using multivariate generalized logit models (ordinal outcomes: absent, low, medium, and high neutralization). Odds ratios (ORs) for the effects of methotrexate and TNFi were adjusted for demographics, IMID, other biologics and immunosuppressives, prednisone, COVID-19 vaccinations (number/type), and infections in the 6 months prior to sampling. The adjusted ORs for methotrexate and TNFi were then pooled in random-effects meta-analyses (separately for the ancestral strains and the Omicron BA1 and BA5 strains). Results: Of 479 individuals (958 samples), 292 (61%) were IBD, 141 (29.4%) were RA, and the remainder were PsA, SpA, and SLE. The mean age was 57 (62.2% female). For both the individual labs and the meta-analyses, the adjusted ORs suggested independent negative effects of TNFi and methotrexate on neutralization. The meta-analysis adjusted ORs for TNFi were 0.56 (95% confidence interval (CI) 0.39, 0.81) for the ancestral strain and 0.56 (95% CI 0.39, 0.81) for BA5. The meta-analysis adjusted OR for methotrexate was 0.39 (95% CI 0.19, 0.76) for BA1. Conclusions: SARS-CoV-2 neutralization in vaccinated IMID was diminished independently by TNFi and methotrexate. As SARS-CoV-2 circulation continues, ongoing vigilance regarding optimized vaccination is required.

Impact of the COVID-19 pandemic on Canadian performing and creative artists: An interpretive descriptive study using the social-ecological model.

Public health restrictions during the Coronavirus-2019 (COVID-19) pandemic in Canada have substantially reduced the work and income of performing and creative artists. We aimed to understand how factors at the public policy, community, organizational, interpersonal and individual levels affected Canadian performing and creative artists' health and livelihood during the pandemic. We interviewed 14 creative and performing artists from an academic hospital-based healthcare center in Toronto, Canada. In addition, we conducted secondary data analysis on an existing set of 17 transcribed interviews from a quality improvement study that included relevant information to answer the present study's research question. We applied an interpretive descriptive approach to our qualitative inquiry and used the social-ecological model (SEM) as our analytic framework. We identified factors at all levels of the SEM that tended to synergistically affect the health and livelihood of artists during the COVID-19 pandemic. Public health restrictions and government financial assistance programs have downstream effects on other levels. During the pandemic, many artists sensed an overwhelming loss of community, financial instability, and limited access to healthcare; which in turn affected their health. For those who accessed financial assistance programs, the stability of income afforded time for rest without the stress of food insecurity or housing instability. Use of the SEM as an analytic framework reflects the multidirectional intricacy and dynamic interplay among factors operating within and across all five levels, bringing to light potential areas of improvement at various levels to strengthen resilience and reduce risk factors associated with artists' health and healthcare access. Findings also accentuated the fragility of precarious work that inundates the performing arts industry, which emphasizes the need for interventions and policies to address this issue. Such interventions might include financial support programs for artists, access to affordable healthcare services, and efforts to strengthen social support networks within the arts community.

Building Frontline Capability for Shared Decision-Making (SDM) in a Major Academic Oncology Center Caring for People With Non-Small Cell Lung Cancer: Performance Outcomes of a SDM Simulation Training Program.

There is a growing body of evidence on shared decision-making (SDM) training programs worldwide. However, there is wide variation in program design, duration, effectiveness, and evaluation in both academia (ie, medical school) and the practice setting. SDM training has been slow to integrate in practice settings. A pilot study of 6 multidisciplinary clinicians was conducted using quantitative and qualitative methods to evaluate changes in participant understanding and implementation of SDM in the practice setting. A 2-rater criterion-based evaluation method was used to assess a simulation-based case study role-play program using 7 domains of SDM pre and post training. The authors assessed whether clinicians addressed each of the 7 domains or what fraction of each domain was addressed as part of their simulation case study role-play performance. Focus groups were conducted pre- and postintervention to provide feedback to participants and to understand the clinician experience in greater detail. The increase in improvement in SDM ranged from 17% to 37%, and 7 of 8 domains for which participants were rated showed significant improvement. The areas of greatest improvement were seen in determining a patient's goals/preferences, including risk tolerance regarding treatments (+37%) and values and self-efficacy (+37%). The results of this study reveal a significant shift in clinician awareness of a patient's goals, preferences, and values. Postintervention, clinicians began to understand the value of building a partnership with their patients whereby the patient becomes an active participant in their clinical care.

Next day sentinel node biopsy for melanoma after lymphoscintigraphy using 99mTc-labelled nanocolloid does not adversely affect long-term outcomes.

Sentinel Lymph Node Biopsy (SLNB) is an important management tool for early-stage melanoma. Different radiopharmaceuticals are used internationally to localise the sentinel node using lymphoscintigraphy (LSG) before surgery. Recent reports have suggested that a delayed interval between LSG and SLNB using 99mTc-labelled nanocolloid tracer has an adverse survival impact, but not with 99mTc-labelled antimony sulphide colloid. This study aims to analyse survival outcome in a prospective cohort of melanoma patients undergoing same day or next day SLNB after LSG using 99mTc-labelled nanocolloid. Outcome data were reviewed for patients undergoing SLNB, stratified by time interval between LSG and SLNB at a single UK academic centre. Kaplan-Meier survival analysis was used to assess overall survival (OS), melanoma-specific survival (MSS) and progression-free survival (PFS). Cox multivariable regression analysis identified independent risk factors. 925 patients had LSG using the 99mTc-nanocolloid tracer between 2009 and 2019, with a median follow-up of 6.36years. No difference was seen on univariate analysis in OS, MSS, PFS, or nodal recurrence between patients undergoing same day or next day SLNB (Log-rank P = 0.437, 0.293, 0.587, 0.342 respectively). In addition, nodal recurrence as first site or anytime site of recurrence in SLNB negative patients was similar between the groups (Log-rank P = 0.093 and 0.457 respectively). Stratified analysis of time did not demonstrate an outcome difference (MSS Log-rank P = 0.938). Cox multivariable regression did not show time interval to independently influence OS, MSS or PFS. We do not find a significant effect on long-term outcomes when SLNB is performed the day after LSG with 99mTc-labelled nanocolloid tracer. We infer that tracer migration is not clinically significant within 24h of injection based on long term clinical outcome data.

Parastomal hernia after ileal conduit: Incidence, natural history and risk factors.

Parastomal hernias are a challenging complication of digestive ostomies. Ileal-conduit parastomal hernias after cystectomy have specific aspects. The aim of this study was to describe the incidence and natural history of ileal-conduit parastomal hernias in order to guide their management, as well as to identify risk factors to prevent them. All consecutive patients undergoing cystectomy with a Bricker's ileal conduit in 3 academic centers were retrospectively identified. Data were collected regarding their medical history prior to cystectomy, the operation, the postoperative period, imaging results within 5years of follow-up, and the onset and timing of clinically or radiologically diagnosed ICPH. Among 577 patients included in the study, 115 (20.6%) developed an ICPH during the study period. Most patients did not present any symptom and the diagnosis was made at imaging in 74.8% of them. Most hernias were detected between 1 and 2years after the cystectomy, with a mean time to diagnosis of 12.4months. At multivariate analysis, overweight and obesity were independent risk factors for developing an ICPH (adjusted hazard ratio [aHR] 1.96; p=0.046), while a trans-rectus position of the ostomy was a significant protective factor (aHR 0.45; p=0.011). A PH develops in almost 20% of patients after ileal conduit urinary diversion, with a mean time of onset of 12.4months. It is often a subclinical condition detected at medical imaging. Obesity increases the risk, while passing the ileal-conduit through the rectus muscle can help to prevent it.

Preoperative geriatric assessment to predict functional outcome after major urologic operations: Results from a multicenter study

IntroductionMajor urological tumor surgery entails a severe risk of unexpected adverse events, persistent functional deterioration, and death in older patients. The Erlangen Index (EI) geriatric assessment tool has previously been shown to predict incomplete functional recovery following major urological tumor surgery in an elderly patient collective. We prospectively evaluated assessment tools including EI in a multicenter setting. Materials and methodsA total of 340 patients over the age of 65 were assessed prospectively before and after cystectomy, prostatectomy, or renal tumor surgery at three academic centers in Germany and Austria. Endpoints were long-term functional deterioration (Activities of daily living (ADL) measured by Barthel-Index) at day 30 and day 180, and mortality at day 180. ResultsIn this study 58 (17.0 %) patients underwent cystectomy, 140 (41.2 %) prostatectomy and 142 (41.8 %) a kidney tumor operation. Mean age was 74.8 years. ADL impairment as a measure of incomplete recovery at day 30 and 180 after surgery were recorded in 47.6 % and 37.4 % of cases, respectively. The EI showed good sensitivity for mortality at day 180 (reference cohort: 85 %, validation center 1: 100 %, validation center 2: 50 %) and for ADL impairment at day 180 (reference cohort 75.4 %, validation center 1 72.3 %, validation center 2 83.3 %). ConclusionElderly patients with a poor performance status have a high risk of persistent functional deterioration. Data from this multicenter external validation trial confirms the EI as an accurate and reliable tool to identify patients with high risk of mortality or persistent postoperative functional impairment.

Trends in advanced practice providers in plastic and reconstructive surgery, 2013–2021

This restrospective cohort study of Medicare payment data found increases in the number of advanced practice providers who bill for plastic and reconstructive surgery care. The growth in advanced practice providers is expected to continue in plastic surgery, and further investigation is needed to effectively integrate these providers into academic centers.
