Association of Metabolic Derangement and Postoperative Outcomes in Hernia Repair With Component Separation: A Propensity Score-matched Nationwide Analysis.

INTRODUCTION: Metabolic syndrome (MetS) is characterized by cardiometabolic abnormalities such as hypertension, obesity, diabetes, or dyslipidemia. This study aims to evaluate the association of MetS on the postoperative outcomes of ventral, umbilical, and epigastric hernia repair using component separation. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was used to identify patients who underwent ventral, umbilical, and epigastric hernia repair with component separation between 2015 and 2021. MetS status was defined as patients receiving medical treatment for diabetes mellitus and hypertension, with a body mass index greater than 30 kg/m2. Propensity matching was performed to generate two balanced cohorts with and without MetS. T-tests and Fisher's Exact tests assessed group differences. Logistic regression models evaluated complications between the groups. RESULTS: After propensity score matching, 3930 patients were included in the analysis, with 1965 in each group (MetS versus non-MetS). Significant differences were observed in the severity and clinical presentation of hernias between the groups. The MetS cohort had higher rates of incarcerated hernia (39.1% versus 33.2%; P < 0.001), and recurrent ventral hernia (42.7% versus 36.5%; P < 0.001) compared to the non-MetS cohort. The MetS group demonstrated significantly increased rates of renal insufficiency (P = 0.026), unplanned intubation (P = 0.003), cardiac arrest (P = 0.005), and reoperation rates (P = 0.002) than the non-MetS cohort. Logistic regression models demonstrated higher likelihood of postoperative complications in the MetS group, including mild systemic complications (OR 1.25; 95%CI 1.030-1.518; P = 0.024), severe systemic complications (OR 1.63; 95%CI 1.248-2.120; P < 0.001), and reoperation (OR 1.47; 95%CI 1.158-1.866; P = 0.002). There were no significant differences in the rates of 30-d wound complications between groups. CONCLUSIONS: The presence of metabolic derangement appears to be associated with adverse postoperative medical outcomes and increased reoperation rates after hernia repair with component separation. These findings highlight the importance of optimizing preoperative comorbidities as surgeons counsel patients with MetS.

The Impact of Health Literacy on Trust in Online Plastic Surgery Content: A Nationwide Analysis.

INTRODUCTION: On most online platforms, just about anyone can disseminate plastic surgery (PS) content regardless of their educational or professional background. This study examines the general public's perceptions of the accuracy of online PS content and the factors that contribute to the discernment of credible information. METHODS: The Amazon Mechanical Turk crowdsourcing platform was used to survey adults in the United States. The survey assessed respondent demographics, health literacy (HL), and perceptions of online PS content accuracy. T-tests, Chi-square tests, and post hoc analyses with Bonferroni corrections assessed differences between HL groups. Multivariate linear regressions assessed associations between sociodemographic variables and perceptions of online content. RESULTS: In total, 428 (92.0%) of 465 complete responses were analyzed. The median age of respondents was 32 y (interquartile range: 29-40). Online sources were predominantly perceived to have a high degree of accuracy, with mean scores of various platforms ranging from 3.8 to 4.5 (1 = not accurate at all; 5 = extremely accurate). The low HL group perceived social media sites and review sites to be more accurate than the high HL respondents, particularly for Reddit (P = 0.004), Pinterest (P = 0.040), and Snapchat (P = 0.002). CONCLUSIONS: There is a concerning relationship between low HL and the perceptions of the accuracy of online PS sources. This study underscores the need for education campaigns, the development of trustworthy online resources, and initiatives to improve HL. By fostering a more informed public, individuals seeking PS can make better informed decisions.

Beyond Accreditation Council for Graduate Medical Education Required Scholarship: The Academic Journey of Plastic Surgery Residents.

INTRODUCTION: Research productivity is an important part of required Accreditation Council for Graduate Medical Education scholarship during residency training and critical to trainees who intend to pursue careers in academia. This study aims to determine plastic surgery residents' experiences with and attitudes toward research. METHODS: Accredited independent (52) and integrated (86) plastic surgery program websites were manually searched for currently active residents' names and email addresses. Identified residents were emailed a survey consisting of 25 questions through Research Electronic Data Capture. RESULTS: A total of 45 plastic surgery residents responded to the survey request (14.6% response rate). Respondents were 57% female and 43% male, with an average age of 30.7 y. At the time of survey participation, 95% of surgery residents were involved in research endeavors, voluntarily or as part of their residency training. Of the respondents, 13 (32%) previously participated in a research fellowship compared to 28 (68%) respondents who did not. Interestingly, respondents who completed fellowships were 2.84 times (95% confidence interval: 0.52-15.38, P = 0.2269) more likely to intend continuing research endeavors after residency. Participants were most in agreement with statements suggesting their research fellowship benefitted their application in the plastic surgery match process (4 [interquartile range (IQR): 4, 4]), improved their ability to conduct research (4 [IQR: 4, 4]), and helped to better understand medical literature (4 [IQR: 3, 4]). CONCLUSIONS: Plastic surgery programs' robust research emphasis has a favorable translation into residents' self-perceived understanding of medical literature and clinical knowledge.

Improving the accuracy of automated gout flare ascertainment using natural language processing of electronic health records and linked Medicare claims data.

BACKGROUND: We aimed to determine whether integrating concepts from the notes from the electronic health record (EHR) data using natural language processing (NLP) could improve the identification of gout flares. METHODS: Using Medicare claims linked with EHR, we selected gout patients who initiated the urate-lowering therapy (ULT). Patients' 12-month baseline period and on-treatment follow-up were segmented into 1-month units. We retrieved EHR notes for months with gout diagnosis codes and processed notes for NLP concepts. We selected a random sample of 500 patients and reviewed each of their notes for the presence of a physician-documented gout flare. Months containing at least 1 note mentioning gout flares were considered months with events. We used 60% of patients to train predictive models with LASSO. We evaluated the models by the area under the curve (AUC) in the validation data and examined positive/negative predictive values (P/NPV). RESULTS: We extracted and labeled 839 months of follow-up (280 with gout flares). The claims-only model selected 20 variables (AUC = 0.69). The NLP concept-only model selected 15 (AUC = 0.69). The combined model selected 32 claims variables and 13 NLP concepts (AUC = 0.73). The claims-only model had a PPV of 0.64 [0.50, 0.77] and an NPV of 0.71 [0.65, 0.76], whereas the combined model had a PPV of 0.76 [0.61, 0.88] and an NPV of 0.71 [0.65, 0.76]. CONCLUSION: Adding NLP concept variables to claims variables resulted in a small improvement in the identification of gout flares. Our data-driven claims-only model and our combined claims/NLP-concept model outperformed existing rule-based claims algorithms reliant on medication use, diagnosis, and procedure codes.

A needs assessment for simulation in African surgical education.

INTRODUCTION: There is a critical need for comprehensive surgical training in African countries given the unmet surgical burden of disease in this region. Collaborative and progressive initiatives in global surgical education will have the greatest impact on trainees. Little is known about surgical education needs from the perspective of practicing surgeons and trainees in low-middle-income countries (LMICs). Even less is known about the potential role for simulation to augment training. METHODS: A modified Delphi methodology with 2 rounds of responses was employed to survey program directors (PD) and associate program directors (APD) of Pan-African Association of Christian Surgeons (PAACS) general surgery residency programs across eight low-middle-income countries in Africa. 3 PD/APDs and 2 surgical residents participated in semi-structured interviews centered around the role of simulation in training. Descriptive analysis was performed to elicit key themes and illustrative examples. RESULTS: The survey of program directors revealed that teaching residents the psychomotor skills need to perform intracorporeal suturing was both high priority and desired in multiple training sites. Other high priority skills were laparoscopic camera driving and medial visceral rotation. The interviews revealed a specific desire to perform laparoscopic surgery and a need for a simulation curriculum to familiarize staff and trainees with laparoscopic techniques. Several barriers to laparoscopic surgery exist, such as lack of staff familiarity with the equipment, lack of public buy in, and lack of generalizable and adaptable educational modules. Trainees saw utility in the use of simulation to optimize time in the operating room and sought opportunities to improve their laparoscopic skills. CONCLUSION: Faculty and surgical trainees in LMICs have interest in learning advanced surgical techniques, such as laparoscopy. Developing a simulation curriculum tailored to the trainees' local context has the potential to fill this need.

Development of "Explore Plastic Surgery": An Educational Program for Medical Students Without Home Residency Programs.

BACKGROUND: Medical students who attend institutions without plastic surgery residency programs are at a disadvantage in the plastic surgery match. We developed an educational program for medical students without home programs called Explore Plastic Surgery to provide an overview of the steps toward a career in plastic surgery. The purpose of this study was to assess the impact, utility, and success of the novel program. METHODS: Pre- and postevent surveys were distributed to participants. Survey data were analyzed including participant demographics, perceptions of barriers unique to those without home programs, and the overall event utility. RESULTS: Two hundred seventeen students registered for the program. Ninety-five participants completed the pre-event survey (44%), and of those, 57 participants completed the post-event survey (60%). There was an increase in understanding of the steps toward a career in plastic surgery ( P < 0.001), confidence in overcoming barriers ( P = 0.005), and level of comfort in reaching out to faculty for opportunities ( P = 0.01). There was a decrease in the perceived negative impact that attending medical schools without a home program will have on their abilities to pursue careers in plastic surgery ( P = 0.006). CONCLUSIONS: After the event, participants demonstrated an increase in their confidence in overcoming barriers and a decrease in their perceptions that attending an institution without a home program would negatively impact their ability to pursue plastic surgery. Initiatives focused on early exposure and recruitment of medical students may be important to promote accessibility and diversity within plastic surgery.

Geographic Variability of Genital Gender-Affirming Surgery Centers and Costs of Hospitalization.

PURPOSE: The cost of gender-affirming surgery (GAS) is an important component of healthcare accessibility for transgender patients. However, GAS is often prohibitively expensive, particularly as there are inconsistencies in insurance coverages. Variability in hospital costs has been documented for other types of nonplastic surgery procedures; however, this analysis has not been done for GAS. To better understand the financial barriers impairing access to equitable transgender care, this study analyzes the distribution of hospitals that perform genital GAS and the associated costs of inpatient genital GAS. METHODS: This is a study of the 2016-2019 National Inpatient Sample database. Transgender patients undergoing genital GAS were identified using International Classification of Diseases, Tenth Revision, diagnosis and procedure codes, and patients undergoing concurrent chest wall GAS were excluded. Descriptive statistics were done on patient sociodemographic variables, hospital characteristics, and hospitalization costs. χ2 test was used to assess for differences between categorical variables and Mood's median test was used to assess for differences between continuous variable medians. RESULTS: A total of 3590 weighted genital GAS encounters were identified. The Western region (50.8%) and Northeast (32.3%) performed the greatest proportion of GAS, compared with the Midwest (9.1%) and the South (8.0%) (P < 0.0001). The most common payment source was private insurance (62.8%), followed by public insurance (27.3%). There were significant differences in the variability of median hospital costs across regions (P < 0.0001). The South and Midwest had the greatest median cost for vaginoplasty ($19,935; interquartile range [IQR], $16,162-$23,561; P = 0.0009), while the West had the greatest median cost for phalloplasty ($26,799; IQR, $19,667-$30,826; P = 0.0152). Across both procedures, the Northeast had the lowest median cost ($11,421; IQR, $9155-$13,165 and $10,055; IQR, $9,013-$10,377, respectively). CONCLUSIONS: There is significant regional variability in the number of GAS procedures performed and their associated hospitalization costs. The identified disparities in insurance coverage present an area of possible future improvement to alleviate the financial burden GAS presents to gender-discordant individuals. The variability in cost suggests a need to evaluate variations in care, leading to cost standardization.

Continuing Insurance Coverage for Flap-Based Breast Reconstruction: Is There a Reservation Cost Related to a Woman's Abdominal Flap Choice?

BACKGROUND: The recent proposed alterations to the Centers for Medicare and Medicaid Services regulations, although subsequently reversed on August 21, 2023, have engendered persistent concerns regarding the impact of insurance policies on breast reconstruction procedures coverage. This study aimed to identify factors that would influence women's preferences regarding autologous breast reconstruction to better understand the possible consequences of these coverage changes. METHODS: A survey of adult women in the United States was conducted via Amazon Mechanical Turk to assess patient preferences for breast reconstruction options, specifically deep inferior epigastric perforator (DIEP) and transverse rectus abdominis myocutaneous (TRAM) flap surgery. The Cochrane-Armitage test evaluated trends in flap preferences concerning incremental out-of-pocket payment increases. RESULTS: Of 500 total responses, 485 were completed and correctly answered a verification question to ensure adequate attention to the survey, with respondents having a median (interquartile range) age of 26 (25-39) years. When presented with the advantages and disadvantages of DIEP versus TRAM flaps, 78% of respondents preferred DIEP; however, as DIEP's out-of-pocket price incrementally rose, more respondents favored the cheaper TRAM option, with $3804 being the "indifference point" where preferences for both procedures converged (P < 0.001). Notably, respondents with a personal history of breast reconstruction showed a higher preference for DIEP, even at a $10,000 out-of-pocket cost (P = 0.04). CONCLUSIONS: Out-of-pocket cost can significantly influence women's choices for breast reconstruction. These findings encourage a reevaluation of emergent insurance practices that could potentially increase out-of-pocket costs associated with DIEP flaps, to prevent cost from decreasing equitable patient access to most current reconstructive options.

Outcomes of patients in rural communities undergoing autologous breast reconstruction: A comparison of cost and patient demographics with implications for rural health policy.

BACKGROUND: Patients with breast cancer living in rural areas are less likely to undergo breast reconstruction. Further, given the additional training and resources required for autologous reconstruction, it is likely that rural patients face barriers to accessing these surgical options. Therefore, the purpose of this study is to determine if there are disparities in autologous breast reconstruction care among rural patients on the national level. METHODS: The Healthcare Cost and Utilization Project Nationwide Inpatient Sample Database was queried from 2012 to 2019 using ICD9/10 codes for breast cancer diagnoses and autologous breast reconstruction. The resulting data set was analyzed for patient, hospital, and complication-specific information with counties comprised of less than 10,000 inhabitants classified as rural. RESULTS: From 2012 to 2019, 89,700 weighted encounters for autologous breast reconstruction involved patients who lived in non-rural areas, while 3605 involved patients from rural counties. The majority of rural patients underwent reconstruction at urban teaching hospitals. However, rural patients were more likely than non-rural patients to have their surgery at a rural hospital (6.8% vs. 0.7%). Rural-county residing patients had lower odds of receiving a deep inferior epigastric perforator (DIEP) flap compared to non-rural-county residing patients (OR 0.51 CI: 0.48-0.55, p < .0001). Further, rural patients were more likely to experience infection and wound disruption than urban patients (p < .05), regardless of where they underwent surgery. Complication rates were similar among rural patients who received care at rural hospitals versus urban hospitals (p > .05). Meanwhile, the cost of autologous breast reconstruction was higher (p = .011) for rural patients at an urban hospital ($30,066.2, SD19,965.5) than at a rural hospital ($25,049.5, SD12,397.2). CONCLUSION: Patients living in rural areas face disparities in health care, including lower odds of being potentially offered gold-standard breast reconstruction treatments. Increased microsurgical option availability and patient education in rural areas may help alleviate current disparities in breast reconstruction.

The value of microvascular breast reconstruction: Cost equivalence of TRAM and DIEP flaps implications in the era of CMS reforms.

BACKGROUND: Recent CMS billing changes have raised concerns about insurance coverage for deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study compared the costs and utilization of transverse rectus abdominis myocutaneous (TRAM), DIEP, and latissimus dorsi (LD) flaps in breast reconstruction. METHOD: The study utilized the National Inpatient Sample database to identify female patients who underwent DIEP, TRAM, and LD flap procedures from 2016 to 2019. Key data such as patient demographics, length of stay, complications, and costs (adjusted to 2021 USD) were analyzed, focusing on differences across the flap types. RESULTS: A total of 17,770 weighted patient encounters were identified, with the median age being 51. The majority underwent DIEP flaps (73.5%), followed by TRAM (14.2%) and LD (12.1%) flaps. The findings revealed that DIEP and TRAM flaps had a similar length of stay (LOS), while LD flaps typically had a shorter LOS. The total hospital charges to costs using cost-to-charge ratio were also comparable between DIEP and TRAM flaps, whereas LD flaps were significantly less expensive. Factors such as income quartile, primary payer of hospitalization, and geographic region significantly influenced flap choice. CONCLUSION: The study's results appear to contradict the prevailing notion that TRAM flaps are more cost-effective than DIEP flaps. The total hospital charges to costs using cost-to-charge ratio and hospital stays associated with TRAM and DIEP flaps were found to be similar. These findings suggest that changes in the insurance landscape, which may limit the use of DIEP flaps, could undermine patient autonomy while not necessarily reducing healthcare costs. Such policy shifts could favor less costly options like the LD flap, potentially altering the landscape of microvascular breast reconstruction.

Barriers of Three-Dimensional Printing in Craniofacial Plastic Surgery Practice: A Pilot Study and Literature Review.

OBJECTIVE: Three-dimensional printing (3Dp) and modeling have demonstrated increasing utility within plastic and reconstructive surgery (PRS). This study aims to understand the prevalence of how this technology is utilized in craniofacial surgery, as well as identify barriers that may limit its integration into practice. METHODS: A survey was developed to assess participant demographics, characteristics of 3Dp use, and barriers to utilizing three-dimensional technologies in practice. The survey was distributed to practicing craniofacial surgeons. A secondary literature review was conducted to identify solutions for barriers and potential areas for innovation. RESULTS: Fifteen complete responses (9.7% response rate) were analyzed. The majority (73%) reported using three-dimensional modeling and printing in their practice, primarily for surgical planning. The majority (64%) relied exclusively on outside facilities to print the models, selecting resources required to train self and staff (55%), followed by the cost of staff to run the printer (36%), as the most common barriers affecting 3Dp use in their practice. Of those that did not use 3Dp, the most common barrier was lack of exposure (75%). The literature review revealed cost-lowering techniques with materials, comparability of desktop commercial printers to industrial printers, and incorporation of open-source software. CONCLUSIONS: The main barrier to integrating 3Dp in craniofacial plastic and reconstructive surgery practice is the perceived cost associated with utilizing the technology. Ongoing literature highlights the cost-utility of in-house 3Dp technologies and practical cost-saving methods. The authors' results underscore the need for broad exposure for currently practicing attendings and trainees in 3Dp practices and other evolving technologies.

Air Versus Saline in Tissue Expanders: A Systematic Review of the Literature.

BACKGROUND: There has been a greater focus in recent literature proposing air to be a superior medium to saline in tissue expanders. This study aims to review the literature and assess the quality of data on the efficacy and safety of air as an alternative medium to saline in tissue expanders, in the setting of postmastectomy two-stage reconstruction. METHODS: A systematic review regarding air inflation of tissue expanders was conducted using PubMed, Embase, Cochrane Library, and Web of Science. The methods followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Three reviewers separately performed data extraction and comprehensive synthesis. RESULTS: A total of 427 articles were identified in our search query, of which 11 met the inclusion criteria. Three pertained to inflation with room air, and eight pertained to inflation with CO2 using the AeroForm device. They were comparable to decreased overall complication rates in the room air/CO2 cohort compared to saline, although statistical significance was only observed in one of five two-arm studies. Investigating specific complications in the five two-arm studies, significantly lower rates of skin flap necrosis were only observed in two CO2-based studies. Studies rarely discussed other safety profile concerns, such as the impacts of air travel, radiation planning, and air extravasation beyond descriptions of select patients within the cohort. CONCLUSION: There is insufficient evidence to suggest improved outcomes with room air inflation of tissue expanders. Further work is needed to fully characterize the benefits and safety profiles of air insufflation before being adopted into clinical practice.

An Institutional Analysis of Early Postoperative Free Tissue Transfer Takeback Procedures.

BACKGROUND: Postoperative free tissue transfer reexploration procedures are relatively infrequent but associated with increased overall failure rates. This study examines the differences between flaps requiring takeback versus no takeback, as well as trends in reexploration techniques that may increase the odds of successful salvage. METHODS: A retrospective review was conducted on all free tissue transfers performed at our institution from 2011 to 2022. Patients who underwent flap reexploration within 30 days of the original procedure were compared with a randomly selected control group who underwent free flap procedures without reexploration (1:2 cases to controls). Univariate and multivariate logistic regression analyses were performed. RESULTS: From 1,213 free tissue transfers performed in the study period, 187 patients were included in the analysis. Of the total flaps performed, 62 (0.05%) required takeback, and 125 were randomly selected as a control group. Free flap indication, flap type, reconstruction location, and number of venous anastomoses differed significantly between the two groups. Among the reexplored flaps, 8 (4.3% of the total) had a subsequent failure while 54 (87.10%) were salvaged, with significant differences in cause of initial flap failure, affected vessel type, and salvage technique. CONCLUSION: Free tissue transfers least prone to reexploration involved breast reconstruction in patients without predisposition to hypercoagulability or reconstruction history. When takeback operations were required, salvage was more likely in those without microvascular compromise or with an isolated venous injury who required a single exploratory operation.

Non-Linear Lymphatic Anatomy in Breast Cancer Patients Prior to Axillary Lymph Node Dissection: A Risk Factor For Lymphedema Development.

Immediate lymphatic reconstruction (ILR) at the time of axillary lymph node dissection (ALND) has become increasingly utilized for the prevention of breast cancer related lymphedema. Preoperative indocyanine green (ICG) lymphography is routinely performed prior to an ILR procedure to characterize baseline lymphatic anatomy of the upper extremity. While most patients have linear lymphatic channels visualized on ICG, representing a non-diseased state, some patients demonstrate non-linear patterns. This study aims to determine potential inciting factors that help explain why some patients have non-linear patterns, and what these patterns represent regarding the relative risk of developing postoperative breast cancer related lymphedema in this population. A retrospective review was conducted to identify breast cancer patients who underwent successful ILR with preoperative ICG at our institution from November 2017-June 2022. Among the 248 patients who were identified, 13 (5%) had preoperative non-linear lymphatic anatomy. A history of trauma or surgery of the affected limb and an increasing number of sentinel lymph nodes removed prior to ALND appeared to be risk factors for non-linear lymphatic anatomy. Furthermore, non-linear anatomy in the limb of interest was associated with an increased risk of postoperative lymphedema development. Overall, non-linear lymphatic anatomy on pre-operative ICG lymphography appears to be a risk factor for developing ipsilateral breast cancer-related lymphedema. Guided by the study's findings, when breast cancer patients present with baseline non-linear lymphatic anatomy, our institution has implemented a protocol of prophylactically prescribing compression sleeves immediately following ALND.

Depression as a risk factor for adverse outcomes and increased healthcare utilization in bariatric surgery patients.

INTRODUCTION: Depression is strongly associated with obesity and is common among patients undergoing bariatric surgery. Little is known about the impact of depression on early postoperative outcomes or its association with substance use. METHODS: The Michigan Bariatric Surgery Collaborative is a statewide quality improvement program that maintains a large clinical registry. We evaluated patients undergoing primary Roux-en-Y gastric bypass or sleeve gastrectomy between 2017 and 2022. Patients self-reported symptoms of depression (PHQ-8) and use of alcohol (AUDIT-C), smoking, prescription opiates, and marijuana at baseline. Preoperative PHQ-8 scores stratified patients based on severity: no depression (0-4), mild (5-9), moderate (10-14), or severe (15-24). We compared 30-day outcomes and substance use between patients with and without depression. RESULTS: Among 44,301 patients, 30.8% had some level of depression, with 19.8% mild, 7.5% moderate, and 3.5% severe. Patients with depression were more likely to have an extended length of stay (LOS) (> 3 days) than those without depression (no depression 2.1% vs. severe depression 3.0%, p = 0.0452). There were no significant differences between no depression and severe depression groups in rates of complications (5.7% vs. 5.2%, p = 0.1564), reoperations (0.9%, vs. 0.8%, p = 0.7394), ED visits (7.7% vs. 7.8%, p = 0.5353), or readmissions (3.2% vs. 3.9%, p = 0.3034). Patients with severe depression had significantly higher rates of smoking (9.7% vs. 12.5%, p < 0.0001), alcohol use disorder (8.6% vs. 14.0%, p < 0.0001), opiate use (14.5% vs. 22.4%, p < 0.0001) and marijuana use (8.4%, vs. 15.5%, p = 0.0008). CONCLUSIONS: This study demonstrated that nearly one-third of patients undergoing bariatric surgery have depression, with over 10% in the moderate to severe range. There was a significant association between preoperative depressive symptoms and extended LOS after bariatric surgery, as well as higher rates of smoking and use of marijuana, prescription opiates and alcohol. There was no significant effect on adverse events or other measures of healthcare utilization.

Fluid Overload and AKI After the Norwood Operation: The Correlation and Characterization of Routine Clinical Markers.

The purpose of this study was to determine the correlation of different methods of assessing fluid overload and determine which metrics are associated with development of acute kidney injury (AKI) in the period immediately following Norwood palliation. This was a retrospective single-center study of Norwood patients from January 2011 through January 2021. AKI was defined using the Kidney Disease Improving Global Outcomes (KDIGO). Patients were separated into two groups: those with AKI and those without. A logistic regression analysis was conducted with AKI at any point in the study period as the dependent variable and clinical and laboratory data as independent variables. Analysis was conducted as a stepwise regression. The coefficients from the logistic regression were then used to develop a cumulative AKI risk score. Spearman correlations were conducted to analyze the correlation of fluid markers. 116 patients were included, and 49 (42.4%) developed AKI. The duration of open chest, duration of mechanical ventilation, need for dialysis, need for extracorporeal membrane oxygenation, and inpatient mortality were associated with AKI (p ≤ 0.05). Stepwise logistic regression demonstrated the following significant independent associations AKI: age at Norwood in days (p < 0.01), blood urea nitrogen (p < 0.01), central venous pressure (p = 0.04), and renal oxygen extraction ratio (p < 0.01). The area under the receiver operating characteristic curve for the logistic regression was 0.74. The fluid markers had weak R-value. Urea, central venous pressure, and renal oxygen extraction ratio are associated with AKI after the Norwood operation. Common clinical metrics used to assess fluid overload are poorly correlated with each other for postoperative Norwood patients.

Sources of Facial Injury Across Age Groups: A Nationwide Overview Using the National Electronic Injury Surveillance System Database.

BACKGROUND: Facial trauma comprises a significant portion of injuries that occur each year in the United States, with injuries ranging from lacerations to complex facial fractures. This study aims to provide a broad epidemiologic overview of facial trauma in the United States to direct preventative safety measures. METHODS: A cross-sectional study was conducted utilizing the National Electronic Injury Surveillance System database to identify the weighted national incidence of facial injuries from 2017 to 2021. Descriptive and inferential statistical analysis was used to compare the demographics of patients, the settings where the injury occurred, and the products resulting in the injury. RESULTS: A total of 8,465,538 out of 64,312,132 weighted encounters involved facial injuries. Less than 10 years was the highest-represented age group (36.8%). The most frequent disposition was treated and released (91.1%), with increasing age associated with higher rates of hospitalization (odds ratio: 1.04, P < 0.001). Cases predominantly occurred at home (49.0%), and the most common type of injury was laceration (36.5%). At-home injuries increased with age, comprising 39.2% of facial injuries for 21 to 40 years, 52.0% for 41 to 64 years, and 58.0% for older than 65 years. Building structures (21.4%) were the most prevalent source of injury, composed predominantly of floors (58.3%) and ceilings and walls (10.4%). CONCLUSIONS: There is an understated burden of at-home facial injuries across all age groups, beyond the pediatric and geriatric population. Fall prevention and home environmental hazards education could benefit all ages, reducing the incidence of facial trauma.

Preferences and Barriers of Male Patients Seeking Aesthetic Procedures.

BACKGROUND: As social attitudes toward plastic surgery continue to evolve, the prevalence of men seeking plastic surgery has been increasing. By delving into the factors that encourage male patients to seek plastic surgery and the obstacles they encounter, this study aims to facilitate the development of more inclusive and effective approaches for this population. METHOD: An anonymous 41-question survey was conducted among adult men in the USA via the Amazon Mechanical Turk crowdsourcing platform. Questions assessed demographic information and identified factors that influenced males to seek plastic surgery care, the barriers they experienced while seeking care, and their preferences. Multivariate logistic regression was used to assess relationships between demographic variables and likelihood of undergoing cosmetic surgery. RESULTS: Four hundred and eleven complete responses were analyzed. The median (IQR) age of respondents was 32 (30, 40) years old. Of the respondents, 60% had undergone cosmetic surgery. Functional improvement (40%), personal aspiration (32%), and partners' opinions (22%) were the most commonly cited reasons for undergoing procedures. The most common barriers faced by this population were recovery time following a procedure (52%), perceived risk of complications (48%), cost (43%), fear of being identified as having had plastic surgery (32%), and surgeons not being able to meet expectations (31%). Eighty-nine percent of respondents who underwent plastic surgery procedures reported facing at least one barrier. Multivariate regression demonstrated that higher education levels were strongly associated with a likelihood of undergoing cosmetic surgery (p < 0.001). Income (p = 0.44) and region (p = 0.23) did not significantly affect the likelihood of undergoing plastic surgery. CONCLUSION: Despite improving societal stigma, many male patients continue to face barriers when obtaining plastic surgery care. Efforts may be made to alleviate these barriers and surgeons looking to expand their practice may benefit from increased outreach to male patients. This may be compounded with improved education targeting stigma and risks of procedures, increasing male-specific marketing communications to make them feel welcome in an industry predominantly focused on female patients, and offering male-tailored procedures.

Edematous Dermal Thickening on Magnetic Resonance Imaging as a Biomarker for Lymphatic Surgical Outcomes.

Background and Objectives: One of the surgical treatments for breast cancer-related lymphedema (BCRL) is debulking lipectomy. The aim of this study is to investigate whether dermal thickness could be utilized as an objective indicator of post-operative changes following debulking. Materials and Methods: A retrospective review of BCRL patients who underwent debulking lipectomy was conducted. MRI-based dermal thickness was measured by two separate trained readers at 16 regions of the upper extremity. Pre- and post-operative reduction in dermal thickness was compared across the affected and unaffected (control) arms for each patient. The Wilcoxon rank sum test was used to assess for significant change. Univariate linear regression was used to assess the relationship between dermal thickness reduction and changes to LYMPH-Q scores, L-Dex scores, and relative volume change. Results: Seventeen patients were included in our analysis. There was significant reduction in dermal thickness at 5/16 regions in the affected arm. Dermal thickness change was significantly correlated with LYMPH-Q scores, L-Dex scores, and relative volume change in 2/16 limb compartments. There was predominant dermal thickening in the dorsal compartment of the upper arm and in the ventral and ulnar compartments of the forearm. Conclusions: Dermal thickness shows promising utility in tracking post-operative debulking procedures for breast cancer-related lymphedema. Further studies with larger patient populations and a variety of imaging modalities are required to continue to develop a clinically objective and reproducible method of post-surgical lymphedema staging and monitoring.

Gender and Nationality Trends in Manuscripts Published in Prominent Gastroenterology Journals Between 1997 and 2017.

BACKGROUND: Gender disparities remain in the field of gastroenterology (GI) despite the decreasing gender gap in the medical field overall. We sought to examine primary and last female authorship as a marker of academic opportunity and advancement to assess the proportion of women publishing in GI over 20 years (1997-2017). METHODS: In this observational study, we assessed the gender and nationality of primary and last authors of original research manuscripts in three GI journals (Gastroenterology, Gut, and American Journal of Gastroenterology) across a 20-year period in 5-year intervals (in 1997, 2002, 2007, and 2012). We used a validated gender-determining algorithm, genderize.io, to classify gender. Our primary outcome was the proportion of female primary and last authors, with secondary measures assessing trends in gender and nationality. RESULTS: Through the Genderize.io gender database, we were able to identify the gender for 3,673 (95.9%) of primary author names and 3,504 (95.4%) of last author names in the 3,615 manuscripts evaluated. Overall, there was a significant increase in female primary authors over time, from 18.1% in 1997 to 42.6% in 2017, a 6.0% increase per 5-year period (95% CI 4.8-7.2%). A similar trend was found for female last authors, however, at a slower rate, from 8.3% in 1997 to 24.7% in 2017, a 3.5% increase per 5 years (95% CI 2.5-4.4%). These trends were noted cumulatively, and in each journal individually. Manuscripts with a female last author were more likely to demonstrate a female primary author. CONCLUSION: Female authorship in high-impact gastroenterology journals has increased over time. Last authorship has lagged primary authorship in female representation and has increased more slowly over time. Interventions to reduce gender disparity in GI research should focus on the transition from first to last authorship.
