RESUMEN
Decades of previous efforts to develop renal-sparing polyene antifungals were misguided by the classic membrane permeabilization model1. Recently, the clinically vital but also highly renal-toxic small-molecule natural product amphotericin B was instead found to kill fungi primarily by forming extramembraneous sponge-like aggregates that extract ergosterol from lipid bilayers2-6. Here we show that rapid and selective extraction of fungal ergosterol can yield potent and renal-sparing polyene antifungals. Cholesterol extraction was found to drive the toxicity of amphotericin B to human renal cells. Our examination of high-resolution structures of amphotericin B sponges in sterol-free and sterol-bound states guided us to a promising structural derivative that does not bind cholesterol and is thus renal sparing. This derivative was also less potent because it extracts ergosterol more slowly. Selective acceleration of ergosterol extraction with a second structural modification yielded a new polyene, AM-2-19, that is renal sparing in mice and primary human renal cells, potent against hundreds of pathogenic fungal strains, resistance evasive following serial passage in vitro and highly efficacious in animal models of invasive fungal infections. Thus, rational tuning of the dynamics of interactions between small molecules may lead to better treatments for fungal infections that still kill millions of people annually7,8 and potentially other resistance-evasive antimicrobials, including those that have recently been shown to operate through supramolecular structures that target specific lipids9.

BACKGROUND: Patient and provider race and gender concordance (patient and physician identify as the same race/ethnicity or gender) may impact patient experience and satisfaction. OBJECTIVE: We sought to examine how patient and physician racial and gender concordance effect patient satisfaction with outpatient clinical encounters. Furthermore, we examined factors that changed satisfaction among concordant and discordant dyads. DESIGN: Consumer Assessment of Healthcare Provider and Systems (CAHPS) Patient Satisfaction Survey Scores were collected from outpatient clinical encounters between January 2017 and January 2019 at the University of California, San Francisco. PARTICIPANTS: Patients who were seen in the eligible time period, who voluntarily provided physician satisfaction scores. Providers with fewer than 30 reviews and encounters with missing data were excluded. MAIN MEASURES: Primary outcome was rate of top satisfaction score. The provider score (1-10 scale) was dichotomized as "top score (9-10)" and "low scores (<9)." KEY RESULTS: A total of 77,543 evaluations met inclusion criteria. Most patients identified as White (73.5%) and female (55.4%) with a median age of 60 (IQR 45, 70). Compared to White patients, Asian patients were less likely to give a top score even when controlling for racial concordance (OR: 0.67; CI 0.63-0.714). Telehealth was associated with increased odds of a top score relative to in-person visits (OR 1.25; CI 1.07-1.48). The odds of a top score decreased by 11% in racially discordant dyads. CONCLUSIONS: Racial concordance, particularly among older, White, male patients, is a nonmodifiable predictor of patient satisfaction. Physicians of color are at a disadvantage, as they receive lower patient satisfaction scores, even in race concordant pairs, with Asian physicians seeing Asian patients receiving the lowest scores. Patient satisfaction data is likely an inappropriate means of determining physician incentives as such may perpetuate racial and gender disadvantages.
RESUMEN
BACKGROUND: As perception of penile curvature varies widely, we sought to understand how adults perceive curvature and how these opinions compare with those of patients with curvature, specifically Peyronie's disease (PD). AIM: To investigate the perspectives of curvature correction from adults with and without PD, as well as differences within demographics. METHODS: A cross-sectional survey was administered to adult patients and nonpatient companions in general urology clinics at 3 institutions across the United States. Men, women, and nonbinary participants were recruited. Patients were grouped as having PD vs andrology conditions without PD vs general urology conditions plus companions. The survey consisted of unlabeled 2-dimensional images of penis models with varying degrees of curvature. Participants selected images that they would want surgically corrected for themselves and their children. Univariable and multivariable analyses were performed to identify demographic variables associated with willingness to correct. OUTCOMES: Our main outcome was to detect differences in threshold to correct curvature between those with and without PD. RESULTS: Participants were grouped as follows: PD (n = 141), andrology (n = 132), and general (n = 302) . Respectively, 12.8%, 18.9%, and 19.9% chose not to surgically correct any degree of curvature (P = .17). For those who chose surgical correction, the mean threshold for correction was 49.7°, 51.0°, and 51.0° (P = .48); for their children, the decision not to correct any degree of curvature was 21.3%, 25.4%, and 29.3% (P = .34), which was significantly higher than correction for themselves (P < .001). The mean threshold for their children's correction was 47.7°, 53.3°, and 49.4° for the PD, andrology, and general groups (P = .53), with thresholds no different vs themselves (P = .93). On multivariable analysis, no differences were seen in demographics within the PD and andrology groups. In the general group, participants aged 45 to 54 years and those who identified as LGBTQ (lesbian, gay, bisexual, transgender, queer) had a higher threshold for correction as compared with their counterparts when factoring other demographic variables (63.2° vs 48.8°, P = .001; 62.1° vs 50.4°, P = .05). CLINICAL IMPLICATIONS: With changing times and viewpoints, this study stresses the importance of shared decision making and balancing risks and benefits to correction of penile curvature. STRENGTHS AND LIMITATIONS: Strengths include the broad population surveyed. Limitations include the use of artificial models. CONCLUSION: No significant differences were seen in the decision to surgically correct curvature between participants with and without PD, with participants being less likely to choose surgical correction for their children.

Introduction: Patient satisfaction has been shown to changes based on the distance a patient to see their physician. We sought to examine the effects of telehealth on patient satisfaction. Methods: We examined patient satisfaction survey scores from outpatient clinics at University of California, San Francisco. Patient home and clinic addresses were used to calculate distance in kilometers (km). Outcomes were "top scores (9-10)" and "low scores (<9)." Results: Of 103,124 evaluations that met inclusion criteria, those where patient traveled >100 km for in-person visits had more top scores (84%) than those traveled <10 km (80.2%). Relative to in-person visits, telehealth was associated with an increased odds (odds ratio [OR]: 1.48) of receiving a top score at all distances. Those traveling >100 km had the highest odds of top score for telehealth (OR: 1.86). Conclusions: Patients receiving care through telehealth, particularly those far from the outpatient clinic, are more likely to provide high patient satisfaction scores for the visit provider.

OBJECTIVE: To systematically aggregate and summarize existing data on fistula prevalence among patients with a history of pelvic radiotherapy for prostate cancer. MATERIALS AND METHODS: We queried PubMed, Embase, and Web of Science on October 7, 2020 for peer-reviewed publications pertaining to radiation-induced fistulas in the pelvis. For meta-analysis, we used the random-effects model. We used the I2 statistic to quantify heterogeneity and the Newcastle-Ottawa Scale to assess risk of bias. RESULTS: Our final meta-analysis included 6 cohort studies with a total of 7665 patients exposed to pelvic radiotherapy between 1967 and 2013. Median follow-up time was 35.5 months (IQR 33.5-57.5). Pooled prevalence of radiation-induced fistula across all 6 cohort studies was 0.2% (95% CI: 0.1-0.4, I2 = 0.000%, P < .608). In subgroup analysis, we did not detect significant heterogeneity in fistula prevalence in patients who were re-irradiated (0.3%, 95% CI: 0.1-0.4; P = .762) or patients on concurrent chemotherapy (0.4%, 95% CI: -0.3 -1.2; P = .664) compared to those receiving their first course of radiotherapy alone. No randomized controlled trials met inclusion criteria due to ambiguous and inconsistent reporting language for fistula occurrence. CONCLUSION: There is limited published literature reporting fistula as an adverse event of prostate cancer radiotherapy, especially in the medium and long-term period. Patients undergoing pelvic radiotherapy for prostate cancer appear at low short-term risk for developing fistulas. Adverse event reporting in randomized controlled trials merits greater granularity where fistulas should be reported with specificity rather than aggregating into broad categories of genitourinary or gastrointestinal adverse events.

Peyronie's disease (PD) is a fibrotic disorder of the tunica albuginea that may result in penile deformity, pain, a palpable plaque, and erectile dysfunction. In order to understand the psycho-sexual impacts of PD on patients and their partners, we selected three online forums containing the largest number of threads on PD. Threads focusing on the psycho-sexual impacts posted from January 1, 2011 to January 1, 2021 were compiled, and thematic analysis was performed on Dedoose. There were 277 unique posters, including 225 patients and 52 partners. Eighty-four categories and five themes were developed including information and social support, physical symptoms, psycho-sexual symptoms, treatment and effect, and impacts on partners and relationship. Emotional distress including depressed mood (n = 75, 33.3%) and feelings of isolation (n = 41, 18.2%) was prevalent. Partners developed sexual dysfunction including sexual dissatisfaction (n = 11, 21.2%) and dyspareunia (n = 4, 7.7%). Relationships experienced disruption (n = 14, 5.1%) or termination (n = 10, 3.6%). Posters received psychological treatment including psychotherapy (n = 20, 8.9%) and antidepressants (n = 17, 7.6%). Of these, 12 reported improvement and 11 stated no improvement. On these forums, psychological burden affecting individuals with PD and their partners is reported. Few seek help from a psychologist or therapist, and psychological distress may persist even after successful PD treatment. Further research is needed to identify strategies for effective psychological management.

PURPOSE: To determine the incidence of and risk factors for symptomatic venous thromboembolism (VTE) after hip arthroscopy (HA) and thromboprophylaxis prescription utilization for this procedure. METHODS: The PearlDiver Mariner database was queried using Current Procedural Terminology codes to identify adult patients (aged ≥ 18 years) who underwent HA between 2010 and 2020. Patient demographic information, including age, oral contraceptive use, and medical comorbidities, as well as perioperative thromboprophylaxis utilization, was recorded using International Classification of Diseases codes and National Drug Codes. The incidence of postoperative VTE within 90 days was determined. Multivariate logistic regression was used to identify predictors of perioperative thromboprophylaxis utilization and risk factors for VTE. RESULTS: The queried records identified 60,181 patients who met the inclusion criteria. Of these patients, 367 (0.6%) experienced VTE, including deep venous thrombosis (0.5%) and/or pulmonary embolism (0.2%). Approximately 2.1% of patients used thromboprophylaxis, including aspirin (1.1%), low-molecular-weight heparin (0.9%), and oral factor Xa inhibitors (0.1%). Oral contraceptive pill use (adjusted odds ratio [aOR], 2.16; 95% confidence interval [CI], 1.34-3.46), obesity (aOR, 1.37; 95% CI, 1.05-1.79), and a history of malignancy (aOR, 1.69; 95% CI, 1.12-2.54) were associated with increased odds of experiencing VTE. Perioperative thromboprophylaxis (aOR, 0.52; 95% CI, 0.19-1.39) was not significantly associated with decreased odds of experiencing VTE. However, obesity (aOR, 1.17; 95% CI, 1.00-1.38) and hypertension (aOR, 1.17; 95% CI, 1.02-1.36) were associated with increased odds of thromboprophylaxis prescription utilization. CONCLUSIONS: Although the overall risk of symptomatic VTE after HA remains low, oral contraceptive use, obesity, and a history of malignancy are associated with increased odds of thromboembolic events within 90 days. Routine thromboprophylaxis after HA may not be indicated in all patients but can be considered based on patient-specific risk factors. LEVEL OF EVIDENCE: Level III, retrospective prognostic comparative trial.

PURPOSE: To determine the rate of symptomatic venous thromboembolism (VTE) among patients undergoing arthroscopic knee procedures, risk factors associated with postoperative VTE, and current perioperative thromboprophylaxis prescription patterns associated with this population in the United States. METHODS: Medical records for patients ≥18 years of age were queried from the Mariner database using Current Procedural Terminology codes for knee arthroscopy performed in the United States from 2010 to 2020 in this cross-sectional study. Patients who received thromboprophylaxis and those diagnosed with VTE, including deep-vein thrombosis or pulmonary embolism, within 90 days of surgery were identified using International Classification of Diseases and National Drug Codes. Two multivariable logistic regression models were used to identify VTE risk factors and likelihood of perioperative thromboprophylaxis. Covariates included procedure type, age, oral contraceptive pill (OCP) use, and medical comorbidities. RESULTS: A total of 718,289 patients met inclusion criteria and 7,618 patients (1.06%) experienced VTE, including deep-vein thrombosis (n = 6,394, 0.9%) and/or pulmonary embolism (n = 2,211, 0.3%). A total of 10,769 patients (1.5%) filled perioperative thromboprophylaxis, including aspirin (n = 5,353, 0.7%), low-molecular-weight heparin (n = 4,563, 0.6%), and oral factor Xa inhibitors (n = 947, 0.1%). Perioperative thromboprophylaxis was associated with decreased odds of experiencing VTE (adjusted odds ratio [aOR] 0.65, 95% confidence interval [CI] 0.51-0.80). Procedure types categorized as moderate-to-greater risk were associated with increased odds of VTE (aOR 1.42, 95% CI 1.34-1.50). OCP use (aOR 1.63, 95% CI 1.38-1.91), obesity (aOR 1.17, 95% CI 1.11-1.24), renal disease (aOR 1.33, 95% CI 1.18-1.50) and congestive heart failure (aOR 1.30, 95% CI 1.13-1.50) were associated with increased odds of VTE. CONCLUSIONS: While the overall rate of symptomatic VTE following knee arthroscopy remains low, procedure types that are more complex and generally require restrictive rehabilitation protocols, OCP use, obesity, renal disease, and congestive heart failure are associated with increased odds of postoperative VTE. Conversely, the use of perioperative thromboprophylaxis is associated with significantly lower VTE risk. LEVEL OF EVIDENCE: III, retrospective comparative prognostic trial.

PURPOSE: We describe the lived experience of adults with acquired buried penis (AABP) through thematic analysis of patient interviews. We examine the challenges that patients face and the impacts of surgery. MATERIALS AND METHODS: This mixed-methods study utilized validated instruments and semi-structured interviews to capture pre- and postsurgical outcomes. Semi-structured interviews were conducted with open-ended questions to elicit the impact of AABP on a patient's quality of life in several domains including urinary function, sexual function, interpersonal relationships and mental health. Recruitment was completed once we achieved thematic saturation. RESULTS: Twenty patients participated in the study; 11 underwent surgical treatment for AABP. Semi-structured interviewee responses were coded into 12 different themes and 39 subthemes. The most common themes were problems with urinary (19/20, 95%) and sexual function (19/20, 95%). Most participants (16/20, 80%) reported negative impacts of AABP on social life. Interviewees struggled with relationships (8/20, 40%) and mental health (11/20, 55%), often avoiding romantic relationships and reporting fear of rejection with concomitant depression and/or anxiety. The majority (70%, 14/20) experienced difficulties accessing care. Among patients who underwent surgery, the majority discussed improvement in urinary and sexual function (82% [9/11] and 73% [8/11], respectively). Though weight gain was a precipitating factor, weight loss did not result in symptom improvement. Rather, in 4/20 (20%), weight loss made their condition worse. CONCLUSIONS: Patients living with AABP experience profound negative impacts on quality of life including their urinary and sexual function, social life and mental health. Many patients face issues with access to care.

BACKGROUND: Open fractures, especially of the tibia, require prompt intervention to achieve optimal patient outcomes. While open tibial shaft fractures are common injuries in low- and middle-income countries (LMICs), there is a dearth of literature examining delays to surgery for these injuries in low-resource settings. This study investigated risk factors for delayed management of open tibial fractures in Tanzania. METHODS: We conducted an ad hoc analysis of adult patients enrolled in a prospective observational study at a tertiary referral center in Tanzania from 2015 to 2017. Multivariable models were utilized to analyze risk factors for delayed hospital presentation of ≥2 hours, median time from injury to the treatment hospital, and delayed surgical treatment of ≥12 hours after admission among patients with diaphyseal open tibial fractures. RESULTS: Two hundred and forty-nine patients met the inclusion criteria. Only 12% of patients used an ambulance, 41% were delayed ≥2 hours in presentation to the first hospital, 75% received an interfacility referral, and 10% experienced a delay to surgery of ≥12 hours after admission. After adjusting for injury severity, having insurance (adjusted odds ratio [aOR] = 0.48; 95% confidence interval [CI] = 0.24 to 0.96) and wounds with approximated skin edges (aOR = 0.37; 95% CI = 0.20 to 0.66) were associated with a decreased risk of delayed hospital presentation. Interfacility referrals (2.3 hours greater than no referral; p = 0.015) and rural injury location (10.9 hours greater than urban location; p < 0.001) were associated with greater median times to treatment hospital admission. Older age (aOR = 0.54 per 10 years; 95% CI = 0.31 to 0.95), single-person households (aOR = 0.12 compared with ≥8 people; 95% CI = 0.02 to 0.96), and an education level greater than pre-primary (aOR = 0.16; 95% CI = 0.04 to 0.62) were associated with fewer delays to surgery of ≥12 hours after admission. CONCLUSIONS: Prehospital network and socioeconomic characteristics are associated with delays to open tibial fracture care in Tanzania. Reducing interfacility referrals and implementing surgical cost-reduction strategies may help to reduce delays to open fracture care in LMICs. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

INTRODUCTION: We examined the characteristics and financial outcomes of online crowdfunding campaigns for patients with major urological cancers in the U.S. METHODS: This cross-sectional study analyzed publicly available data from GoFundMe, the largest online medical crowdfunding service, via automated web scraping. Online campaigns from 2010 to 2018 with the following primary cancer types were included: kidney, prostate, bladder and testicular. Financial outcomes were compared using Kruskal-Wallis and Wilcoxon rank-sum tests. Multivariable analyses were utilized to identify predictors of campaign financial outcomes. RESULTS: Kidney cancers were the most frequent online campaign type (478), followed by prostate (379), bladder (202) and testicular (175) malignancies. Urological cancer campaign recipients frequently requested funding for medical expenses (71%) during active treatment (57%). After adjustment, testicular cancer and children's cancer campaigns generated more donations than other urological and adult cancer campaigns (p <0.05). Family and friend-authored campaigns generated more donations and average donation amounts than self-authored campaigns (p <0.05). Campaign narratives focused on disheartening circumstances received fewer donations than narratives focused on the recipient's high moral character or contributions to society (p <0.05), and unclear narratives received the smallest donation amounts (p <0.05). CONCLUSIONS: Urological cancer crowdfunding in the U.S. is primarily used to finance uncovered costs associated with medical care during active treatment. Crowdfunding financial outcomes are likely related to the campaign recipient's age, malignancy type, social network and primary appeal of the narrative. Urologists should be aware of trends in medical crowdfunding in order to better understand the financial burden this patient population faces.
RESUMEN
AIM: To analyse the most recent trends and characteristics of playground equipment-related injuries in children. METHODS: We used the National Electronic Injury Surveillance System database to acquire cases of playground equipment-related injuries in children ≤17 years old between 1995 and 2019. A total of 184 580 unweighted cases met our study inclusion criteria. RESULTS: A total of 5 356 703 (95% confidence interval 4 235 530-6 477 876) emergency department visits for playground-related injuries in the USA were estimated during the study period which was equal to an average of 29.4 annual injuries per 10 000 US population ≤17 years. The mean age was 6.5 (standard error 0.049) years. School-aged (42.7%) and pre-school children (35.3%) accounted for most playground injuries. More than half of the injuries were reported in males (53.6%). Most injuries occurred with climbing apparatuses (36%), followed by swings (25.9%) and slides (20.9%). Overall number of injuries (∆ - 22.3%, P = 0.01) and incidence (∆ - 21.6%, P = 0.01) had a declining trend after 2012. However, reported concussion injuries showed an increasing trend during the study (∆ + 28.3%, P < 0.001). A marked seasonal variation in number of injuries existed with most injuries in May and September. CONCLUSIONS: Although injuries arising from playground equipment have decreased during the past 8 years, there was an increase in number of reported concussions. The outcomes of this study suggested that further efforts should be directed towards such serious injuries.

Amphotericin B (AmB) is a powerful but toxic fungicide that operates via enigmatic small molecule-small molecule interactions. This mechanism has challenged the frontiers of structural biology for half a century. We recently showed AmB primarily forms extramembranous aggregates that kill yeast by extracting ergosterol from membranes. Here, we report key structural features of these antifungal 'sponges' illuminated by high-resolution magic-angle spinning solid-state NMR, in concert with simulated annealing and molecular dynamics computations. The minimal unit of assembly is an asymmetric head-to-tail homodimer: one molecule adopts an all-trans C1-C13 motif, the other a C6-C7-gauche conformation. These homodimers are staggered in a clathrate-like lattice with large void volumes similar to the size of sterols. These results illuminate the atomistic interactions that underlie fungicidal assemblies of AmB and suggest this natural product may form biologically active clathrates that host sterol guests.

OBJECTIVE: To identify the current formats of standardized letters of recommendation (SLORs) and evaluate their characteristics, the distribution of applicants' ratings, correlation between SLOR domain ratings and conventional application metrics, and potential biases. METHODS: We evaluated all applications submitted to our residency program for the 2020-2021 urology match. Two main formats of SLOR were identified. We extracted application characteristics and SLOR domain ratings. RESULTS: Ninety SLORs from 82 applicants were reviewed. Applicants were highly rated among top tiers in both formats. Some correlations were observed between domain ratings and application metrics such as Step 1 and Step 2 Clinical Knowledge scores, and percentage of Honors in core clinical clerkships. No statistically significant differences were found between female and male applicants in terms of domain ratings. Alpha Omega Alpha members received higher ratings in "urology resident potential," "academic urologist potential," and "performance as a sub-intern" domains. Applicants from top 40 US medical schools performed better as sub-interns, and were more likely to be ranked higher. Letters from home institutions were associated with higher ratings in several domains. In-person vs virtual interactions received similar ratings except for "communication". CONCLUSION: While it is promising to observe such number of SLORs submitted for the first time in urology, the current formats could benefit from further refinement in their structures and domains to distinguish between highly qualified urology applicants more efficiently. Given the transition in Step 1 score reporting to pass/fail outcome, the need for a reliable urology-specific SLOR will be critical.

OBJECTIVE: To assess provider and practice characteristics that drive opioid prescription behavior using the American Urological Association census data. METHODS: Stratified weighted analysis using 1,157 census samples was performed to represent 12,660 urologists who practiced in the United States in 2018. We compared urologists according to their opioid prescription patterns to evaluate factors and motivations behind opioid use in the post-operative setting. RESULTS: Overall, 11,205 (88.5%) urologists prescribe opioids in the post-operative setting. The presence of procedure-specific institutional prescribing guidelines was associated with a greater tendency to prescribe ≤10 pills, and lesser tendency to prescribe 11 to 49 and ≥50 tablets following open abdominal (P = .003), laparoscopic (P < .001), scrotal (P < .001), and endoscopic surgeries (P < .001). The presence of institutional prescribing guidelines was associated with decreasing opioid prescriptions over a three-year period whereas not having guidelines was associated with an unchanged prescription practice over time. Basing current prescriptions on what was given to prior patients was reported by 85% and was more likely to result in an unchanged amount of prescriptions over time (29.2% vs 13.3%, P = .007). Motivations to avoid patient phone calls were reported by 23.8% and were more likely to increase the opioids provided within the next 3 years (3.2% vs 0.1%, P < .001). CONCLUSION: Practitioners who endorsed using institutional guidelines prescribed fewer opioids following all types of surgery and were more likely to decrease their prescription behavior over time. This data supports continued efforts to provide urologists with more evidence-based guidance on best practice opioid prescribing in the future.

CASE: A 29-year-old man previously treated with closed reduction and intramedullary nail (IMN) fixation for a right tibial shaft fracture presented with complaint of the foot pointing outward compared with uninjured side. He was diagnosed with tibial malrotation, and a novel intraoperative imaging technique was used for correction. CONCLUSION: Literature suggests that the prevalence of tibial malrotation after IMN fixation is greater than previously thought. This case highlights the need for a simple and reliable intraoperative approach to guide and confirm correction of tibial malrotation after IMN fixation, and it demonstrates a technique that can be implemented with immediate results.

BACKGROUND: The obesity paradox has been recently demonstrated in trauma patients, where improved survival was associated with overweight and obese patients compared to patients with normal weight, despite increased morbidity. Little is known whether this effect is mediated by lower injury severity. We aim to explore the association between body mass index (BMI) and renal trauma injury grade, morbidity, and in-hospital mortality. METHODS: A retrospective cohort of adults with renal trauma was conducted using 2013-2016 National Trauma Data Bank. Multiple regression analyses were used to assess outcomes of interest across BMI categories with normal weight as reference, while adjusting for relevant covariates including kidney injury grade. RESULTS: We analyzed 15181 renal injuries. Increasing BMI above normal progressively decreased the risk of high-grade renal trauma (HGRT). Subgroup analysis showed that this relationship was maintained in blunt injury, but there was no association in penetrating injury. Overweight (OR 1.02, CI 0.83-1.25, p = 0.841), class I (OR 0.92, CI 0.71-1.19, p = 0.524), and class II (OR 1.38, CI 0.99-1.91, p = 0.053) obesity were not protective against mortality, whereas class III obesity (OR 1.46, CI 1.03-2.06, p = 0.034) increased mortality odds. Increasing BMI by category was associated with a stepwise increase in odds of acute kidney injury, cardiovascular events, total hospital length of stay (LOS), intensive care unit LOS, and ventilator days. CONCLUSIONS: Increasing BMI was associated with decreased risk of HGRT in blunt trauma. Overweight and obesity were associated with increased morbidity but not with a protective effect on mortality. The obesity paradox does not exist in kidney trauma when injury grade is accounted for.

OBJECTIVE: To describe factors associated with Quality improvement and patient safety (QIPS) participation using 2018 American Urological Association Census data. QIPS have become increasingly important in medicine. However, studies about QIPS in urology suggest low levels of participation, with little known about factors predicting non-participation. METHODS: Results from 2339 census respondents were weighted to estimate 12,660 practicing urologists in the United States. Our primary outcome was participation in QIPS. Predictor variables included demographics, practice setting, rurality, fellowship training, QIPS domains in practice, years in practice, and non-clinical/clinical workload. RESULTS: QIPS participants and non-participants significantly differed in distributions of age (P = .0299), gender (P = .0013), practice setting (P <.0001), employment (employee vs partner vs owner vs combination; P <.0001), and fellowship training (P <.0001). QIPS participants reported fewer years in practice (21.3 vs 25.9, P = .018) and higher clinical (45.2 vs 39.2, P = .022) and non-clinical (8.76 vs 5.28, P = .002) work hours per week. Non-participation was associated with male gender (OR = 2.68, 95% CI 1.03-6.95) and Asian race (OR = 2.59, 95% CI 1.27-5.29) for quality programs and private practice settings (ORs = 8.72-27.8) for patient safety initiatives. CONCLUSION: QIPS was associated with academic settings. Interventions to increase rates of quality and safety participation should target individual and system-level factors, respectively. Future work should discern barriers to QIPS engagement and its clinical benefits.

Managing lower extremity fractures complicated by large soft-tissue defects is challenging for surgeons in low- and middle-income countries, and long-term quality of life (QOL) for these patients is unclear. METHODS: We examined QOL, surgical complications, and longitudinal outcomes in 10 patients with Gustilo-Anderson Classification Type IIIB open tibia fractures seen at an orthopedic institute in Tanzania, from December 2015 to March 2017. Patients completed follow-up at 2-, 6-, 12-, 26-, and 52-week time points, and returned for qualitative interviews at 2.5 years. The primary outcome was QOL, as measured using EuroQoL-5D scores and qualitative semi-structured interview responses. The secondary outcome was rate of complication, as defined by reoperation for deep infection or nonunion. RESULTS: Ten patients enrolled in the study and 7 completed 1-year follow-up. All fractures were caused by road traffic accidents and treated by external fixation. No patients received initial soft-tissue (flap) coverage of the wound. All patients developed an infected nonunion. No patients returned to work at 6 weeks, 3 months, or 6 months. EQ-5D index scores at 1 year were poor (0.71 ± 0.09). Interview themes included ongoing medical complications, loss of employment, reduced income, and difficulty with activities of daily living. CONCLUSIONS: Patients in low- and middle-income countries with IIIB open tibia fractures not treated with appropriate soft-tissue coverage experience poor QOL, high complication rates, and severe socioeconomic effects as a result of their injuries. These findings illustrate the need for resources and training to build capacity for extremity soft-tissue reconstruction in LMICs.
