To investigate the impact of pelvic exenteration (PelvEX) on patient-reported pain, distress, and quality of life along with physiologic indicators of health in cancer survivors with radiated, non-repairable rectourethral fistula (RUF).We reviewed a prospectively maintained quality improvement database of RUF patients at our institution from 2012 to 2020. Patients with radiated, non-repairable RUF who underwent PelvEX and had follow up to 1 year were included. Pain and distress scores were collected preoperatively and at 1-year follow up. Number of narcotic prescriptions in the 3 months before surgery and the year after surgery were abstracted. Short Form 12 surveys were administered in the postoperative period. Serum albumin, creatinine, carbon dioxide, hematocrit, and glucose were abstracted from electronic health records. Statistical analysis was performed using Wilcoxon signed-rank and Mann-Whitney tests.Eleven patients met inclusion criteria. Patient-reported pain significantly decreased at 1 year follow-up compared to preoperative scores (median pre: 4 vs 1 year post: 0, P = .0312). Patient-reported distress significantly decreased pre- versus post-PelvEX (median pre: 5 vs post: 0, P = .0156). At the time of postoperative pain and distress surveys, 9 (82.8%) patients did not have narcotic prescriptions. Postoperative Short Form 12 scores were similar to an age-matched United States population (mental: P = .3125; physical: P = .1484). Serum-based indicators of health were not different in the pre- versus postoperative period (all P.05).PelvEX may be a valuable treatment option to decrease patient-reported pain and distress without compromising quality of life or physiologic health in patients with radiated, non-repairable RUF.

Neurogenic bladder is a common source of morbidity in patients with spina bifida and can cause renal damage. Medical management may include imaging, urodynamic studies (UDS), laboratory testing, clean intermittent catheterization (CIC), and medication. There is ongoing debate regarding the optimal management regimen. Approaches are described by two paradigms: proactive and expectant management. In a proactive approach, invasive interventions like CIC and UDS are initiated before the onset of renal abnormalities. In expectant management, UDS, CIC, and medications are started after abnormalities are identified. In this scoping review, we aim to comprehensively review existing literature on outcomes of proactive and expectant management of neurogenic bladder in patients with spina bifida.We searched multiple databases and screened articles for inclusion using PRISMA-ScR guidelines. Included studies reported clinical outcomes of any aspect of proactive or expectant neurogenic bladder management in patients with spina bifida.Ultimately, 74 articles were included for review including 67 cohort studies, 4 cross-sectional studies, 2 sequential cohort studies, and 1 randomized control trial. Eleven studies directly compared management strategies. There was substantial heterogeneity in study designs, management protocols, and reported outcomes. Most studies addressed multiple simultaneous aspects of management without specifically analyzing individual aspects. However, some commented on individual aspects of management including UDS (13), CIC (32), imaging (7), and medication (5). Although there was no consensus about optimal management, all direct comparisons of paradigms supported a proactive approach.Our review identified a broad body of literature about optimal management of neurogenic bladder. Existing studies vary greatly in terms of treatment protocols, measured outcomes, and management recommendations. Overall, studies that directly compare management are scarce but favor proactive management. Given the implications on clinical outcomes, it is crucial to focus future work on directly comparing management strategies and isolating the effects of different individual management elements.

To investigate the impact of extirpative surgery for pubic bone osteomyelitis with pubovesical fistula on prostate cancer survivors' physical and mental health.The Short Form 12 (SF-12) is a validated instrument for assessing health-related quality of life (HRQOL). We reviewed a prospectively maintained database of patients treated with extirpative surgery for pubovesical fistula from 2017-2021 who completed the SF-12. Wilcoxon signed-rank and McNemar's tests were used to analyze changes in SF-12 following surgery. Narcotic prescriptions in the year before and after surgery were assessed as an additional measure of pain burden.Eighteen patients were included. Four had pre-operative SF-12s, 3 had post-operative SF-12s, and 11 had both. Median age was 76.5 years (IQR 71.75-80.00). All patients had previous radiation for prostate cancer. Compared to global pre-operative scores, post-operative physical composite scores (PCS) significantly increased (29.95 ± 8.59 vs 42.48 ± 7.18; P.001), but mental composite scores (MCS) were similar (45.35 ± 9.98 vs 52.21 ± 8.23). When comparing individual, paired pre-operative and post-operative scores there was a significant improvement in PCS (30.56 ± 9.87 vs 45.45 ± 8.56; P = .005), but not MCS (47.49 ± 6.92 vs 51.60 ± 8.88). Median morphine milligram equivalent significantly decreased in the year post-surgery compared to the year prior (103.1, 33.0-250.9 vs 34.25, 0.0-105.9; P = .0008).For prostate cancer survivors with pubovesical fistula and pubic bone osteomyelitis, urinary diversion with pubic bone resection improves physical functioning and decreases narcotic prescriptions without untoward effects on mental health.

In an era of broader lung sharing, different-team transplantation (DT, procuring team from nonrecipient center) may streamline procurement logistics; however, safety and cost implications of DT remain unclear. To understand whether DT represents a safe means to reduce lung transplant (LTx) costs, we compared posttransplant outcomes and lung procurement and index hospitalization costs among matched DT and same-team transplantation (ST, procuring team from recipient center) cohorts at a single, high-volume institution. We hypothesized that DT reduces costs without compromising outcomes after LTx.Patients who underwent DT between January 2016 to May 2020 were included. A cohort of patients who underwent ST was matched 1:3 (nearest neighbor) based on recipient age, disease group, lung allocation score, history of previous LTx, and bilateral versus single LTx. Posttransplant outcomes and costs were compared between groups.In total, 23 DT and 69 matched ST recipients were included. Perioperative outcomes and posttransplant survival were similar between groups. Compared with ST, DT was associated with similar lung procurement and index hospitalization costs (DT vs ST, procurement: median $65,991 vs $58,847, P = .16; index hospitalization: median $294,346 vs $322,189, P = .7). On average, procurement costs increased $3263 less per 100 nautical miles for DT versus ST; DT offered cost-savings when travel distances exceeded approximately 363 nautical miles.At our institution, DT and ST were associated with similar post-LTx outcomes; DT offered cost-savings with increasing procurement travel distance. These findings suggest that DT may mitigate logistical and financial burdens of lung procurement; however, further investigation in a multi-institutional cohort is warranted.

Textbook surgical outcome (TO) is a novel composite quality measure in lung transplantation (LTx). Compared to 1-year survival metrics, TO may better differentiate center performance, and motivate improvements in care. To understand the feasibility of implementing this metric, we defined TO in LTx using US national data, and evaluated its ability to predict post-transplant outcomes and differentiate center performance.Adult patients who underwent isolated LTx between 2016 and 2019 were included. TO was defined as freedom from post-transplant length of stay 30 days, 90-day mortality, intubation or extracorporeal membrane oxygenation at 72 h post-transplant, post-transplant ventilator support lasting ≥5 days, postoperative airway dehiscence, inpatient dialysis, pre-discharge acute rejection, and grade 3 primary graft dysfunction at 72 h. Recipient and donor characteristics and post-transplant outcomes were compared between patients who achieved and failed TO.Of 8959 lung transplant recipients, 4664 (52.1%) achieved TO. Patient and graft survival were improved among patients who achieved TO (both log-rank P .0001). Among 62 centers, adjusted rates of TO ranged from 27.0% to 72.4% reflecting a wide variability in center-level performance.TO defined using national data may represent a novel composite metric to guide quality improvement in LTx across US transplant centers.In this study we defined textbook outcome (TO) for lung transplantation (LTx) using US national data. We found that achievement of TO was associated with improved post-transplant survival, and wide variability in center-level LTx performance. These findings suggest that TO could be readily implemented to compare quality of care among US LTx centers.

The introduction of antibiotics has significantly reduced morbidity and mortality from microbial infections, but the rise of antibiotic-resistant and multidrug-resistant microbes is of increasing clinical concern. Few studies have examined the prevalence and impact of antibiotic resistance in common antenatal infections.This study aimed to determine whether pregnant women with a urine culture positive for antibiotic-resistant or multidrug-resistant gram-negative bacteria are at increased risk of developing pyelonephritis than pregnant women infected with antibiotic-susceptible organisms.This was a retrospective cohort study of pregnant women with asymptomatic bacteriuria or acute cystitis from a single health system from July 2013 to May 2019. Women with gram-negative antibiotic-resistant (resistance to 1-2 antibiotic classes) and multidrug-resistant (resistance to ≥3 antibiotic classes) lower urinary tract infections were compared with women with antibiotic-susceptible urinary tract infections in terms of demographic, infectious, antepartum, and intrapartum data. The primary outcome was pyelonephritis, defined as a billing code for pyelonephritis plus fever or flank pain. The secondary outcomes were length of stay in the hospital because of pyelonephritis, a composite of pyelonephritis complications (renal abscess, sepsis, and intensive care unit admission), and preterm delivery. The differences in the primary outcome were analyzed using multivariate logistic regression.A total of 573 women were eligible for inclusion. Of the 573 women, 334 (58%) had gram-negative bacteria on urine culture. Of the 334 cases, 173 (52%) were antibiotic susceptible, 74 (22%) were antibiotic resistant, and 87 (26%) were multidrug resistant. Women with antibiotic-resistant and multidrug-resistant infections were more likely to have hypertension (P=.004), to be Black (P=.03), to have public insurance (P=.002), and to experience more urinary infections (P=.001). Pyelonephritis was more common in women with antibiotic-resistant (adjusted odds ratio, 2.27; 95% confidence interval, 1.08-4.78) and multidrug-resistant (adjusted odds ratio, 3.06; 95% confidence interval, 1.57-5.96) infections than in women with antibiotic-susceptible urinary tract infections. Length of stay, preterm delivery, and pyelonephritis complications did not differ between antibiotic-susceptible and antibiotic-resistant and multidrug-resistant infections.In an age of increasing antibiotic resistance, more than one-half of pregnant women with bacteriuria experience at least 1 infection with an antibiotic-resistant organism. These resistance patterns have a real clinical impact as pregnant women with antibiotic-resistant gram-negative lower urinary tract infections have an estimated 2- to 3-fold increased odds of developing pyelonephritis.

- Abstract
The CHAIMELEON project aims to set up a pan-European repository of health imaging data, tools and methodologies, with the ambition to set a standard and provide resources for future AI experimentation for cancer management. The project is a 4 year long, EU-funded project tackling some of the most ambitious research in the fields of biomedical imaging, artificial intelligence and cancer treatment, addressing the four types of cancer that currently have the highest prevalence worldwide: lung, breast, prostate and colorectal. To allow this, clinical partners and external collaborators will populate the repository with multimodality (MR, CT, PET/CT) imaging and related clinical data. Subsequently, AI developers will enable a multimodal analytical data engine facilitating the interpretation, extraction and exploitation of the information stored at the repository. The development and implementation of AI-powered pipelines will enable advancement towards automating data deidentification, curation, annotation, integrity securing and image harmonization. By the end of the project, the usability and performance of the repository as a tool fostering AI experimentation will be technically validated, including a validation subphase by world-class European AI developers, participating in Open Challenges to the AI Community. Upon successful validation of the repository, a set of selected AI tools will undergo early in-silico validation in observational clinical studies coordinated by leading experts in the partner hospitals. Tool performance will be assessed, including external independent validation on hallmark clinical decisions in response to some of the currently most important clinical end points in cancer. The project brings together a consortium of 18 European partners including hospitals, universities, R&D centers and private research companies, constituting an ecosystem of infrastructures, biobanks, AI /in-silico experimentation and cloud computing technologies in oncology., Competing Interests: Authors AS, MA were employed by Matical Innovation SL.
