RESUMEN

INTRODUCTION: Localized prostate cancer (PCa) is one of the most common malignancies in the United States. Despite continued refinement of robot assisted radical prostatectomy (RARP) surgical methods, post-surgical erectile dysfunction and urinary incontinence remain significant challenges due to iatrogenic injury of local nervous tissue. Thus, the development of therapeutic strategies, including the use of biologic adjuncts to protect and/or enhance recovery and function of nerves following RARP is of growing interest. Perinatal tissue allografts have been investigated as one such biologic adjunct to nerve sparing RARP. However, knowledge regarding their clinical efficacy in hastening return of potency and continence as well as the potential underpinning biological mechanisms involved remains understudied. Thus, the objective of this literature review was to summarize published basic science and clinical studies supporting and evaluating the use of perinatal allografts for nerve repair and their clinical efficacy as adjuncts to RARP, respectively. METHODS: The literature as of May 2024 was reviewed non-systematically using PubMed, EMBASE, Scopus, and Web of Science databases. The search terms utilized were "robotic prostatectomy", "prostate cancer", "nerve sparing", "perinatal tissue", "allograft", "potency", and "continence" alone or in combination. All articles were reviewed and judged for scientific merit by authors RP and JM, only peer-reviewed studies were considered. RESULTS: Eight studies of perinatal tissue allograph use in RARP were deemed worthy of inclusion in this nonsystematic review. CONCLUSIONS: Incontinence and impotence remain significant comorbidities despite continued advancement in surgical technique. However, basic science research has demonstrated potential neurotrophic, anti-fibrotic, and anti-inflammatory properties of perinatal tissue allografts, and clinical studies have shown that patients who receive an intra-operative prostatic perinatal membrane wrap have faster return to potency and continence.

RESUMEN

INTRODUCTION: Women, underrepresented minorities, and international medical graduates are underrepresented in urology. We sought to compare demographics of leaders in academic urology to urology faculty and academic medical faculty. MATERIALS AND METHODS: The Association of American Medical Colleges provided academic medical faculty demographics. Women, underrepresented minorities, and international medical graduates in leadership roles (department/division chair or full professor) were identified. Fisher's exact tests were performed to compare proportions of those groups in urology leadership to academic urology, academic medicine leadership, and academic medicine. RESULTS: In 2019, there were 179,105 faculty in academic medicine with 41,766 in leadership and 1,614 faculty in urology with 567 in leadership. Significantly fewer women were in urology leadership compared to academic urology (7.4% vs. 22.0%, p < 0.0001), academic medical leadership (7.4% vs. 25.0%, p < 0.0001), and academic medicine (7.4% vs. 42.0%, p < 0.0001). Significantly fewer underrepresented minorities were in urology leadership compared to academic medicine (6.9% vs. 9.4%, p = 0.04) with no significant difference when compared to urology faculty (6.9% vs. 8.1%, p = 0.4) or medical faculty leadership (6.9% vs. 6.4%, p = 0.6). Significantly more international medical graduates were in urology leadership compared to across academic urology, (32% vs. 24%, p = 0.0006), but significantly fewer than those in leadership across all medical specialties (32% vs. 40%, p = 0.0001). CONCLUSIONS: Women and underrepresented minorities are significantly underrepresented in academic urologic leadership while international medical graduates are statistically overrepresented. Considering calls for diversity, equity, and inclusion, these data highlight a need for increased representation in leadership positions in academic urology.

RESUMEN

BACKGROUND: Adults in rural areas have a higher prevalence of obesity and some mental health conditions. The degree to which mental health influences weight loss among rural residents remains unclear. This study evaluated changes in body weight, physical activity, diet, and program engagement outcomes in a cohort of participants with vs. without an affective disorder in a behavioral weight loss trial. METHODS: A sample of 1407 adults with obesity were recruited from rural U.S. primary care practices to participate in a weight loss trial. In this secondary analysis, participants were stratified by those with vs. without an affective disorder at baseline. Mixed models were used to estimate changes in outcomes over 24 months. RESULTS: One-third of participants (n = 468) had an affective disorder. After covariate adjustment, both groups experienced significant weight loss over 24 months, but weight loss was significantly less among those with an affective disorder at all follow-up times (all p's < 0.001; 24-month weight loss -2.7 ±â€¯0.4 vs. -4.8 ±â€¯0.3 kg). Compared to those without an affective disorder, participants with an affective disorder also had significantly less improvement in physical activity and fruit/vegetable consumption, lower attendance at weight loss sessions, and less engagement in setting weight loss goals and strategies. CONCLUSION: Participants with an affective disorder lost less body weight and less improvement in lifestyle measures over 24 months. These trends paralleled reduced engagement in critical intervention activities such as weight loss session attendance. Future interventions should consider additional methods to minimize disengagement in adults with underlying affective disorders.

RESUMEN

BACKGROUND: Persons with disabilities can have physical, mental, intellectual, or sensory impairments which can hinder their social participation. Despite Sustainable Development Goals call for "universal access to sexual and reproductive health (SRH)", women with disabilities (WwDs) continue to experience barriers to access SRH services in Nepal. This study evaluated factors affecting the utilization of SRH services among WwDs in Ilam district, Nepal. METHODS: A mixed-method study with 384 WwDs of reproductive age was conducted in Ilam district, eastern Nepal. Quantitative data were collected using a structured questionnaire. Relationships between utilization of SRH services and associated factors were explored using multivariate logistic regression analysis. Qualitative data were collected from focus groups with female community health volunteers and interviews with WwDs, health workers and local political leaders. They were audio-recorded, translated and transcribed into English and were thematically analyzed. RESULTS: Among 384 respondents (31% physical; 7% vision,16% hearing, 7% voice&speech,12% mental/psychosocial, 9% intellectual, 18% multiple disabilities), only 15% of them had ever utilized any SRH services. No requirement (57%) and unaware of SRH services (24%) were the major reasons for not utilizing SRH services. A majority (81%) of them reported that the nearest health facility was not disability-inclusive (73%), specifically referring to the inaccessible road (48%). Multivariate analysis showed that being married (AOR = 121.7, 95% CI: 12.206-1214.338), having perceived need for SRH services (AOR = 5.5; 95% CI: 1.419-21.357) and perceived susceptibility to SRH related disease/condition (AOR = 6.0; 95% CI:1.978-18.370) were positively associated with the utilization of SRH services. Qualitative findings revealed that illiteracy, poor socioeconomic status, and lack of information hindered the utilization of SRH services. WwDs faced socioeconomic (lack of empowerment, lack of family support), structural (distant health facility, inaccessible-infrastructure), and attitudinal (stigmatization, bad behaviour of health care providers, perception that SRH is needed only for married) barriers to access SRH services. CONCLUSIONS: Utilization of SRH services among WwDs was very low in Ilam district, Nepal. The findings of this study warrant a need to promote awareness-raising programs to WwDs and their family members, sensitization programs to health service providers, and ensure the provision of disability-inclusive SRH services in all health facilities.

RESUMEN

Importance: Rural populations have a higher prevalence of obesity and poor access to weight loss programs. Effective models for treating obesity in rural clinical practice are needed. Objective: To compare the Medicare Intensive Behavioral Therapy for Obesity fee-for-service model with 2 alternatives: in-clinic group visits based on a patient-centered medical home model and telephone-based group visits based on a disease management model. Design, Setting, and Participants: Cluster randomized trial conducted in 36 primary care practices in the rural Midwestern US. Inclusion criteria included age 20 to 75 years and body mass index of 30 to 45. Participants were enrolled from February 2016 to October 2017. Final follow-up occurred in December 2019. Interventions: All participants received a lifestyle intervention focused on diet, physical activity, and behavior change strategies. In the fee-for-service intervention (n = 473), practice-employed clinicians provided 15-minute in-clinic individual visits at a frequency similar to that reimbursed by Medicare (weekly for 1 month, biweekly for 5 months, and monthly thereafter). In the in-clinic group intervention (n = 468), practice-employed clinicians delivered group visits that were weekly for 3 months, biweekly for 3 months, and monthly thereafter. In the telephone group intervention (n = 466), patients received the same intervention as the in-clinic group intervention, but sessions were delivered remotely via conference calls by centralized staff. Main Outcomes and Measures: The primary outcome was weight change at 24 months. A minimum clinically important difference was defined as 2.75 kg. Results: Among 1407 participants (mean age, 54.7 [SD, 11.8] years; baseline body mass index, 36.7 [SD, 4.0]; 1081 [77%] women), 1220 (87%) completed the trial. Mean weight loss at 24 months was -4.4 kg (95% CI, -5.5 to -3.4 kg) in the in-clinic group intervention, -3.9 kg (95% CI, -5.0 to -2.9 kg) in the telephone group intervention, and -2.6 kg (95% CI, -3.6 to -1.5 kg) in the in-clinic individual intervention. Compared with the in-clinic individual intervention, the mean difference in weight change was -1.9 kg (97.5% CI, -3.5 to -0.2 kg; P = .01) for the in-clinic group intervention and -1.4 kg (97.5% CI, -3.0 to 0.3 kg; P = .06) for the telephone group intervention. Conclusions and Relevance: Among patients with obesity in rural primary care clinics, in-clinic group visits but not telephone-based group visits, compared with in-clinic individual visits, resulted in statistically significantly greater weight loss at 24 months. However, the differences were small in magnitude and of uncertain clinical importance. Trial Registration: ClinicalTrials.gov Identifier: NCT02456636.

RESUMEN

PURPOSE: Low-risk prostate cancer (PCa) is primarily managed with Active Surveillance (AS). A subset of these patients have significantly enlarged glands and lower urinary tract symptoms (LUTS) recalcitrant to medical therapy. Radical treatment in this patient population risks compromise to both erectile function and continence. Therefore, our primary aim is to introduce a novel surgical technique, robotic total prostatectomy (RTP), for the management of severely enlarged prostate hyperplasia with concomitant suspicion of low-risk prostate cancer. METHODS: After IRB approval and patient consultation/education, we performed RTP on 12 consecutive patients who presented with low-risk PCa and significantly enlarged prostate glands with LUTS. Inclusion criteria included patients with suspicion of low-risk malignancy, subjective/objective complaint of LUTS, and pre-operative prostate size > 60 g. Preoperative, perioperative and postoperative variables were studied in the following domains: surgical, oncologic, continence and erectile function. RESULTS: A total of 12 patients underwent RTP. Mean preoperative prostate volume and PSA was estimated at 96.96 g and 8.79, respectively. Surgical time, EBL and LOS was estimated at 180.8 min, 189.6 ml, and 2 days, respectively. Post-operative variables confirmed resolution of LUTS (mean PVR 41.78/IPSS 8.3) and efficient oncologic control (mean PSA 0.04), with minimal compromise of sexual function. 100% continence was achieved at 3 months. CONCLUSION: RTP is a novel, efficient surgical procedure for the treatment of patients with at-risk for low-grade malignancy and symptomatic LUTS in an enlarged gland. Expanding the indication to patients with low-risk malignancy, irrespective of prostate size may alleviate the adverse effects of radical treatment in this select subset of patients.

RESUMEN

INTRODUCTION: To compare visual analog scale (VAS) pain scores between patients with a 2-minute versus 10-minute delay of peri-prostatic lidocaine injection prior to transrectal ultrasound-guided prostate biopsies (TRUS-bx). MATERIALS AND METHODS: Eighty patients who underwent standard 12-core TRUS-bx by a single surgeon were prospectively randomized into four different treatment arms: bibasilar injection with a 2-minute delay, bibasilar injection plus a single apical injection with a 2-minute delay, bibasilar injection with a 10-minute delay, and bibasilar injection plus a single apical injection with a 10-minute delay. Patients were asked to report their level of pain on the VAS (0-10, with 10 indicating unbearable pain) at the following intervals: probe insertion (baseline), after each core, and post-procedure. The primary outcome measure was mean VAS score across all 12 cores minus baseline VAS score, which we refer to baseline-adjusted mean VAS score. RESULTS: Baseline-adjusted mean VAS score was significantly higher for the 2-minute delay group compared to the 10-minute delay group (mean: -0.7 versus -1.6, p = 0.025). Subset analysis of biopsies 1-3, 4-6, 7-9 and 10-12 also demonstrated higher baseline-adjusted mean VAS scores in the 2-minute delay group (all p ≤ 0.043). CONCLUSIONS: Lower TRUS-bx VAS scores can be achieved by extending the time from lidocaine injection to onset of prostate biopsy from 2 to 10 minutes.

RESUMEN

PURPOSE: The primary aim of our study was to determine whether an evidence-based rationale could categorize cavernous venous occlusive disease into mild, moderate and severe erectile dysfunction. MATERIALS AND METHODS: A total of 863 patients underwent color duplex Doppler ultrasound from January 2010 to June 2013 performed by a single urologist. We identified a cohort of 75 patients (8.7%) with a diagnosis of cavernous venous occlusive disease based on a unilateral resistive index less than 0.9, and right and left peak systolic velocity 35 cm per second or less after visual sexual stimulation. At a median followup of 13 months patients were evaluated for treatment efficacy. RESULTS: A total of 75 patients with a median age of 60 years (range 19 to 83) and a mean body mass index of 26.3 kg/m(2) (range 19.0 to 39.3) satisfied the criteria of cavernous venous occlusive disease. When substratified into tertiles, resistive index cutoffs were obtained, including mild cavernous venous occlusive disease-81.6 to 94.0, moderate disease-72.6 to 81.5 and severe disease-59.5 to 72.5. Using these 3 groups the phosphodiesterase type 5-inhibitor failure rate (p = 0.017) and SHIM (Sexual Health Inventory for Men) score categories (1 to 10 vs 11 to 20, p = 0.030) were statistically significantly different for mild, moderate and severe cavernous venous occlusive disease. Treatment satisfaction was also statistically significantly different. Penile prosthetic placement was a more common outcome among patients with erectile dysfunction and more severe cavernous venous occlusive disease. CONCLUSIONS: Our retrospective analysis supports a correlation between the phosphodiesterase type 5 inhibitor failure rate, SHIM score and the rate of surgical intervention using resistive index values. Our data further suggest that an evidence-based classification of cavernous venous occlusive disease by color Doppler ultrasound is possible and can triage patients to penile prosthetic placement.

RESUMEN

BACKGROUND: Among patients with diabetes, racial differences in cardiometabolic risk factor control are common. The extent to which differences in medication adherence contribute to such disparities is not known. We examined whether medication adherence, controlling for treatment intensification, could explain differences in risk factor control between black and white patients with diabetes. METHODS: We identified three cohorts of black and white patients treated with oral medications and who had poor risk factor control at baseline (2009): those with glycated hemoglobin (HbA1c) >8 % (n = 37,873), low-density lipoprotein cholesterol (LDL-C) >100 mg/dl (n = 27,954), and systolic blood pressure (SBP) >130 mm Hg (n = 63,641). Subjects included insured adults with diabetes who were receiving care in one of nine U.S. integrated health systems comprising the SUrveillance, PREvention, and ManagEment of Diabetes Mellitus (SUPREME-DM) consortium. Baseline and follow-up risk factor control, sociodemographic, and clinical characteristics were obtained from electronic health records. Pharmacy-dispensing data were used to estimate medication adherence (i.e., medication refill adherence [MRA]) and treatment intensification (i.e., dose increase or addition of new medication class) between baseline and follow-up. County-level income and educational attainment were estimated via geocoding. Logistic regression models were used to test the association between race and follow-up risk factor control. Models were specified with and without medication adherence to evaluate its role as a mediator. RESULTS: We observed poorer medication adherence among black patients than white patients (p < 0.01): 50.6 % of blacks versus 39.7 % of whites were not highly adherent (i.e., MRA <80 %) to HbA1c oral medication(s); 58.4 % of blacks and 46.7 % of whites were not highly adherent to lipid medication(s); and 33.4 % of blacks and 23.7 % of whites were not highly adherent to BP medication(s). Across all cardiometabolic risk factors, blacks were significantly less likely to achieve control (p < 0.01): 41.5 % of blacks and 45.8 % of whites achieved HbA1c <8 %; 52.6 % of blacks and 60.8 % of whites achieved LDL-C <100; and 45.7 % of blacks and 53.6 % of whites achieved SBP <130. Adjusting for medication adherence/treatment intensification did not alter these patterns or model fit statistics. CONCLUSIONS: Medication adherence failed to explain observed racial differences in the achievement of HbA1c, LDL-C, and SBP control among insured patients with diabetes.

RESUMEN

An observational cohort analysis was conducted within the Surveillance, Prevention, and Management of Diabetes Mellitus (SUPREME-DM) DataLink, a consortium of 11 integrated health-care delivery systems with electronic health records in 10 US states. Among nearly 7 million adults aged 20 years or older, we estimated annual diabetes incidence per 1,000 persons overall and by age, sex, race/ethnicity, and body mass index. We identified 289,050 incident cases of diabetes. Age- and sex-adjusted population incidence was stable between 2006 and 2010, ranging from 10.3 per 1,000 adults (95% confidence interval (CI): 9.8, 10.7) to 11.3 per 1,000 adults (95% CI: 11.0, 11.7). Adjusted incidence was significantly higher in 2011 (11.5, 95% CI: 10.9, 12.0) than in the 2 years with the lowest incidence. A similar pattern was observed in most prespecified subgroups, but only the differences for persons who were not white were significant. In 2006, 56% of incident cases had a glycated hemoglobin (hemoglobin A1c) test as one of the pair of events identifying diabetes. By 2011, that number was 74%. In conclusion, overall diabetes incidence in this population did not significantly increase between 2006 and 2010, but increases in hemoglobin A1c testing may have contributed to rising diabetes incidence among nonwhites in 2011.

RESUMEN

Zoledronate (ZDA) is a bisphosphonate used to treat hypercalcemia that commonly occurs with malignancy, multiple myeloma, and bone metastases from solid tumors. It acts primarily by decreasing osteoclastic activity, thereby slowing the release of skeletal calcium. However, a potential adverse effect of ZDA is hypocalcemia that can be symptomatic, especially in patients with risk factors such as hypomagnesemia, hypoparathyroidism, renal failure, and vitamin D deficiency. We report the case of a patient with extensive stage small cell lung cancer with multiple osseous and visceral metastases who developed symptomatic hypocalcemia following ZDA administration. Significant clinical improvement occurred following administration of calcium and vitamin D, and his calcium levels returned to normal within a few days. Due to the high incidence of vitamin D deficiency and the low accuracy of clinical risk factors to predict vitamin D deficiency, screening for vitamin D deficiency before administration of ZDA may be appropriate.

RESUMEN

PURPOSE: Antihyperglycemic medication intensification practices among patients with incident diabetes are incompletely understood. We characterized the first intensification the year after oral antihyperglycemic medication initiation among incident diabetes patients. METHODS: This retrospective cohort study across 11 US health systems included adults identified with incident diabetes between 2005 and 2009 who started oral antihyperglycemic monotherapy or combination therapy within 6 months after diabetes identification. We determined intensification, defined as increased index medication dosage, addition of another oral medication, or switch to/addition of insulin 31-365 days after initial antihyperglycemic dispensing. Cox regression was used to assess intensification for patient, temporal, and system covariates, adjusting for glycosylated hemoglobin (HbA1c) as a time-dependent variable. RESULTS: Among 41,233 patients, 33.5% and 45.3% had treatment intensified within 6 and 12 months, respectively. This first intensification was most often with increased index medication dosage (78%), least often with insulin (<1%). HbA1c% was strongly associated with intensification (adjusted hazard ratios [HR] 1.59, 3.62, 4.44, and 5.52 for HbA1c 6.5% to <7%, 7% to <7.5%, 7.5 to <8%, and ≥8%, respectively, all P < 0.001, compared with HbA1c < 6.5%). In patients initially on monotherapy, age modified the HbA1c effect: at HbA1c < 7%, the HR differed little between middle-aged and older patients; at HbA1c ≥ 7%, the HR decreased with older age (e.g., age 40-49 years and HbA1c ≥ 8%: HR 8.14; age ≥ 80 years and HbA1c ≥ 8%: HR 4.44; compared with age ≥ 80 years and HbA1c < 6.5%). Within 1 year, 84.3% achieved HbA1c < 8%; 65.1% achieved HbA1c < 7%. CONCLUSIONS: Clinicians appear to be applying treatment intensification guidelines and individualizing therapy by considering patient age, achieving glycemic control among most incident diabetes patients.

Radical nephroureterectomy remains the gold standard treatment for high-risk upper tract urothelial carcinoma. The procedure is subdivided into six main steps: nephrectomy, ureterectomy, bladder cuff excision, cystorrhaphy, template-based lymph node dissection, and perioperative instillation of chemotherapy. Crucial in performing radical nephroureterectomy is successful management of the distal ureter and bladder cuff. Improper, inadequate, or incomplete bladder cuff excision can lead to worse oncologic outcomes and inferior cancer-specific survival. Throughout the years, open, laparoscopic, endoscopic, and robotic approaches have all been reported in performing bladder cuff excision during radical nephroureterectomy. The procedure can be accomplished via an extravesical, intravesical or transvesical manner. Each approach has distinct advantages and disadvantages. The robotic approach offers inherent advantages including improved dexterity, range of motion, and visualization. Critical to choosing an approach, however, is surgeon experience and comfort level. To date, no data suggests superiority of one approach over another. Sound oncologic principles must be adhered to when performing radical nephroureterectomy and include (I) adequate bladder cuff excision, (II) lymphadenectomy, (III) no complications and (IV) negative surgical margins, and (V) perioperative instillation of chemotherapeutic agent. Herein, we describe the various approaches in performing a bladder cuff excision and provide technical commentary supporting the advantages and disadvantages of each technique.

RESUMEN

Gasification is an advanced thermochemical process that converts carbonaceous feedstock into syngas, a mixture of hydrogen, carbon monoxide, and other gases. However, the presence of tar in syngas, which is composed of higher molecular weight aromatic hydrocarbons, poses significant challenges for the downstream utilization of syngas. This Review offers a comprehensive overview of tar from gasification, encompassing gasifier chemistry and configuration that notably impact tar formation during gasification. It explores the concentration and composition of tar in the syngas and the purity of syngas required for the applications. Various tar removal methods are discussed, including mechanical, chemical/catalytic, and plasma technologies. The Review provides insights into the strengths, limitations, and challenges associated with each tar removal method. It also highlights the importance of integrating multiple techniques to enhance the tar removal efficiency and syngas quality. The selection of an appropriate tar removal strategy depends on factors such as tar composition, gasifier operating and design factors, economic considerations, and the extent of purity required at the downstream application. Future research should focus on developing cleaning strategies that consume less energy and cause a smaller environmental impact.

RESUMEN

Objectives: To compare racial differences and pelvis dimensions between Caucasians and African Americans (AAs) and to develop a risk calculator and scoring system to predict the risk of prolonged operative time and presence of positive surgical margins (PSM) based on these dimensions. Materials and Methods: A retrospective review of 88 consecutive patients undergoing robot-assisted laparoscopic prostatectomy with a preoperative prostate MRI conducted. Data extraction included demographic, perioperative, and postoperative oncologic outcomes. Prostate-specific antigen (PSA) was obtained within 3 months postsurgery. Wilcoxon rank sum and Fisher's exact tests were used to compare continuous and categorical data, respectively. Single and multivariable regression analysis were used to determine contribution of each factor to the composite outcomes. A risk score was created based on this analysis for predicting the composite outcome. Results: We identified 88 consecutive patients with localized prostate cancer that underwent a preoperative prostate MRI. No statistically significant differences were found with respect to age, body mass index, or any postoperative outcome. PSA was lower at diagnosis (6.49 vs 9.72, p = 0.006) and operative times were shorter in Caucasians. Rates of PSM (13 vs 14, p = 0.35), biochemical recurrence (4 vs 2, p = 0.69), and complications did not vary between the groups. Caucasians had wider/shallower pelvis dimensions. Based on these variables, we found that the log (odds of OR time >3 hours or PSM) = -5.333 + 1.158 (if AA) +0.105 × PSA +0.076 × F -0.035 × G with an area under the receiver operating characteristic curve = 0.73. Using the predefined variables, patients can be risk stratified for PSM or prolonged operative times. Conclusions: Several pelvis dimensions were found to be shorter/narrower in AAs and were associated with longer operative times. The presented risk calculator and stratification system may be used to predict prolonged operative time or having PSM.

RESUMEN

INTRODUCTION: In 2020, Mayo Clinic launched Advanced Care at Home (ACH), a hospital-at-home program that cares for high-acuity inpatients via remote monitoring and in-person care. Herein, we describe our initial experience utilizing ACH for patients with urologic problems. METHODS: We identified ACH patients treated at Mayo Clinic Florida from July 2020 to August 2022. Records were reviewed to identify those with urologic problems, defined as genitourinary infections, urinary tract obstruction, bleeding, or complications following urologic surgery within 90 days of admission. Demographics, Charlson Comorbidity Index, ACH interventions, length of stay, and hospital readmission were assessed. RESULTS: We identified 563 ACH admissions involving 537 patients, of whom 51 (9%) had illnesses with urologic etiology and 3 (0.6%) were admitted for nonurologic postoperative complications following urologic surgery. Admitting diagnoses included pyelonephritis (n = 51, 91%) and epididymoorchitis (n = 2, 4%). Postoperative diagnoses included cellulitis (n = 1, 2%), congestive heart failure (n = 1, 2%), and diverticulitis (n = 1, 2%). Median Charlson Comorbidity Index of admitted patients was 4 (interquartile range: 3-6.8). Twenty-five patients (46%) underwent 38 urologic procedures within 90 days of admission. Interventions included IV antibiotics (n = 51, 91%), IV fluids (n = 12, 21%), IV antifungals (n = 2, 4%), and oral diuretic therapy (n = 1, 2%). Median length of stay was 3 days (interquartile range: 2-4), and 9 patients (16%) were readmitted within 30 days. A total of 216 inpatient hospital days were saved by utilizing ACH. CONCLUSIONS: ACH appeared to be a feasible alternative to brick-and-mortar inpatient care for patients with genitourinary infections requiring IV antimicrobials.

RESUMEN

OBJECTIVE: To determine the utility of a virtual reality (VR) model constructed using patient-derived clinical imaging to improve patient understanding of localized prostate cancer (PCa) diagnosis and surgical plan. METHODS: Patients undergoing robotic radical prostatectomy were selected and demographic data recorded. Patients completed a questionnaire to assess baseline knowledge of their diagnosis after consultation and shared-decision making with their surgeon. A trained non-clinical staff member then guided the patient through a VR experience to view patient-specific anatomy in a 3-dimensional space. Patients then completed the same questionnaire, followed by an additional post-VR questionnaire evaluating patient satisfaction. Questions 1-7 (patient understanding of prostate cancer and treatment plan) and 11-17 (patient opinion of VR) used a standard Likert scale and Questions 8-10 were multiple choice with 1 correct answer. RESULTS: In total, 15 patients were included with an average age of 64.1 years. 6 of 7 questions showed an improvement after VR (P <.001). The percentage of correct responses on Questions 8-10 was higher after VR but not statistically significant (P >.13). Mean responses range from 4.3 to 4.8 (Likert scale, 1 through 5) for the post-VR questionnaire, with a mean total of 31.9 out of 35. CONCLUSION: This small preliminary investigation of a novel technology to improve the patient experience showed potential as an adjunct to traditional patient counseling. However, due the small sample size and study design, further research is needed to determine the value VR adds to prostate cancer surgical counseling.

RESUMEN

BACKGROUND: This study investigated the impact of surgical modalities on surgeon wellbeing with a focus on burnout, job satisfaction, and interventions used to address neuromusculoskeletal disorders (NMSDs). METHODS: An electronic survey was sent to surgeons across an academic integrated multihospital system. The survey consisted of 47 questions investigating different aspects of surgeons' wellbeing. RESULTS: Out of 245 thoracic and abdominopelvic surgeons, 79 surgeons (32.2 â€‹%) responded, and 65 surgeons (82 â€‹%) were able to be categorized as having a dominant surgical modality. Compared to robotic surgeons, laparoscopic (p â€‹= â€‹0.042) and open (p â€‹= â€‹0.012) surgeons reported more frequent feelings of burnout. The number of surgeons who used any treatment/intervention to minimize the operative discomfort/pain was lower for robotic surgeons than the other three modalities (all p â€‹< â€‹0.05). CONCLUSIONS: NMSDs affect different aspects of surgeons' lives and occupations. Robotic surgery was associated with decreased feelings of burnout than the other modalities.
