Do you want to be a urologist? Gender differences for medical student perception of urology.

INTRODUCTION: Gender inequality has been prevalent in the history of medicine, specifically within surgical specialties. Though there have been advances, urology has remained overwhelmingly male-dominant, with slow growth in female recruitment. This survey study evaluated whether gender-related differences in the perception of urology are present among future applicants that could account for gender disparity seen in recruitment. METHODS: An anonymized, online survey was distributed to medical students enrolled at the Max Rady College of Medicine during the 2022-2023 semester. Attracting and deterring survey statements were created using current literature to guide topics of interest. Participants rated each statement using a five-point Likert scale with optional supplemental qualitative responses. Likert ratings were compared using a Mann-U-Whitney calculation between self-identifying male and female participants. RESULTS: We received 90 responses over six weeks, achieving a response rate of 23%. Female students, compared to their male peers, were deterred by factors such as working in a male-dominated specialty (p<0.001) and working with primarily male patients (p<0.001). There were no significant gender-related differences for statements pertaining to interest in surgery, work-life balance, or exposure to urology. CONCLUSIONS: In this survey study, the biggest deterrents reported by female medical students to entering urology were working in a male-dominated profession and seeing primarily male patients. There were no significant gender-related differences for questions relating to interest in surgery, work-life balance, and exposure to urology.

Evaluating Patient Tolerability for Urological Procedures Under Conscious Sedation: A Prospective Study.

OBJECTIVE: To prospectively evaluate patient-reported tolerability and surgical outcomes of urologic procedures with conscious sedation with or without local anesthesia. Administration of general or spinal anesthesia is associated with anesthetic-related complications, long wait times, and high costs. Using intravenous conscious sedation and/or local anesthesia is an emerging alternative for a myriad of urologic procedures. METHODS: Patients were enrolled from June-August 2021 at a tertiary care hospital. All procedures were completed using fentanyl, midazolam, or both with patient and procedural data recorded upon completion. Patients were telephoned 4-6 weeks post-procedure with a standardized patient tolerability questionnaire. A multivariable adjusted logistic regression analysis was performed to evaluate whether a patient would opt for conscious sedation again as opposed to general anesthesia. RESULTS: A total of 196 procedures were performed by 6 attending urologists with an overall success rate of 98.5% and 0% intraoperative complication rate. At 4-6 weeks follow-up, 85.6% of patients reported they would opt for conscious sedation as opposed to general anesthesia. Predictors of opting for conscious sedation in the future were older age (Odds Ratio (OR): 1.049; P = .017) and surgeon perceived level of patient tolerability (OR: 2.124; P <.001, scored 1-10). CONCLUSION: Physician directed, nursing administered IV conscious sedation is a viable alternative for various urologic procedures and has minimal risk of perioperative complications.

Chronic industrial perturbation and seasonal change induces shift in the bacterial community from gammaproteobacteria to betaproteobacteria having catabolic potential for aromatic compounds at Amlakhadi canal.

Escalating proportions of industrially contaminated sites are one of the major catastrophes faced at the present time due to the industrial revolution. The difficulties associated with culturing the microbes, has been circumvent by the direct use of metagenomic analysis of various complex niches. In this study, a metagenomic approach using next generation sequencing technologies was applied to exemplify the taxonomic abundance and metabolic potential of the microbial community residing in Amlakhadi canal, Ankleshwar at two different seasons. All the metagenomes revealed a predominance of Proteobacteria phylum. However, difference was observed within class level where Gammaproteobacteria was relatively high in polluted metagenome in Summer while in Monsoon the abundance shifted to Betaproteobacteria. Similarly, significant statistical differences were obtained while comparing the genera amongst contaminated sites where Serratia, Achromobacter, Stenotrophomonas and Pseudomonas were abundant in summer season and the dominance changed to Thiobacillus, Thauera, Acidovorax, Nitrosomonas, Sulfuricurvum, Novosphingobium, Hyphomonas and Geobacter in monsoon. Further upon functional characterization, the microbiomes revealed the diverse survival mechanisms, in response to the prevailing ecological conditions (such as degradation of aromatic compounds, heavy metal resistance, oxidative stress responses and multidrug resistance efflux pumps, etc.). The results have important implications in understanding and predicting the impacts of human-induced activities on microbial communities inhabiting natural niche and their responses in coping with the fluctuating pollution load.

Urachal xanthogranuloma: a rare but important case presenting as a urachal mass.

BACKGROUND: A urachal mass is a relatively rare presentation to the urologists' practice, often requiring radical surgical excision for a definitive diagnosis. Xanthogranulomatous inflammation of the urachus is an extremely rare entity with few cases reported worldwide, and to the best of our knowledge, no cases reported in the western world. CASE PRESENTATION: In this case, a 55-year-old male patient presented with bothersome lower urinary tract symptoms and computed tomography findings demonstrating a urachal mass that was worrisome for urachal carcinoma. Following surgical intervention, histopathology revealed urachal xanthogranuloma. Post-operatively, the patient recovered well, and eventually, he had symptomatic and radiologic improvement. CONCLUSION: This case brings awareness to a rare presentation of a urachal mass-urachal xanthogranuloma. While operative intervention was both diagnostic and therapeutic, we highlight the challenge in differentiating between benign and malignant processes for urachal masses. Herein, we show the importance of including urachal xanthogranuloma in the differential diagnosis of a urachal mass to prevent further morbidity associated with the treatment of this disease.

Autologous stem cell transplantation for multiple myeloma in the novel agent era: Systematic review of Indian data and implications for resource constrained settings.

Treatment of multiple myeloma has undergone significant advances in the last two decades, leading to meaningful improvement in overall and progression free survival. The incurable nature of disease necessitates serial sequencing of treatment options and continuous therapy once disease remission is achieved. Autologous stem cell transplantation (ASCT) has continued to offer a meaningful survival advantage with a consistent reduction in toxicity and costs. Despite the advent of newer drugs leading to deeper and sustained responses, ASCT continues to be the standard of care for all eligible patients and is ostensibly more cost effective than continued treatment with newer agents. However, ASCT continues to be underutilized in India, due to concerns about cost, safety, and sporadic expertize. We present a systematic review of available data on ASCT for multiple myeloma from India to evaluate safety and efficacy of the procedure, and provide evidence re-affirming its utility in resource constrained settings.

Distinctive Attributes of Indian Patients With Classical BCR::ABL1 Negative Myeloproliferative Neoplasms: Unified Clinical and Laboratory Data.

INTRODUCTION: We report one of the largest single center data from a mixed referral setting in India describing baseline characteristics and outcomes of patients with classical BCR::ABL1 negative myeloproliferative neoplasms (MPNs). MATERIALS AND METHODS: Patients diagnosed from June 2019 to 2022 were included. Workup and treatment was as per current guidelines. RESULTS: Diagnosis comprised polycythemia vera (PV) in 51(49%), ET in 33(31.7%) and prefibrotic primary myelofibrosis (MF) pre fibrotic myelofibrosis (prePMF) and myelofibrosis in 10(9.6%) patients each. Median age at diagnosis was 52 years for PV and ET, 65.5 for MF and 79 years for prePMF. Diagnosis was incidental in 63(56.7%) and after thrombosis in 8(7.2%) patients. Baseline next generation sequencing (NGS) was available for 63(60.5%) patients. Driver mutations in PV: JAK2 in 80.3%; in ET: JAK2 in 41%, CALR in 26%, MPL in 2.9%; in prePMF JAK2 in 70%, CALR in 20%, MPL in 10%, and in MF: JAK2 in 10%, MPL in 30% and CALR in 40%. Seven novel mutations were detected of which 5 were potentially pathogenic on computational analysis. After median follow up of 30 months, 2 patients had disease transformation and none had new episodes of thrombosis. Ten patients died, most commonly with cardiovascular events(n = 5,50%). Median overall survival was not reached. Mean OS time was 10.19 years(95%CI, 8.6 to 11.74) and mean time to transformation was 12.2 years(95% CI,11.8 to 12.6). CONCLUSION: Our data indicates comparatively indolent presentation of MPNs in India with younger age and lower risk of thrombosis. Further follow up will enable correlation with molecular data and guide modification of age based risk stratification models.

Localized aggressive angiomyxoma of axilla: A rare case report.

ABSTRACT: Aggressive angiomyxoma (AAM) is a rare mesenchymal locally aggressive tumor arising in the pelvis and perineal region in females. On the other hand, extragenital AAMs are extremely rare, specifically in males. We are reporting male AAM which involves only axillary region along with its pathological features. To confirm it, immunohistochemistry (IHC) was done. In sum, pathological examination and IHC aid in distinguishing this lesion and help in differentiating it from other tumors of similar histology. Furthermore, it also aids in planning treatment.

Ureteroscopy under conscious sedation: A proof-of-concept study.

INTRODUCTION: Ureteroscopy (URS) is commonly performed under general anesthesia (GA) to maximize patient tolerability and minimize surgical complications; however, given the improvements in endoscopic technology and risks associated with GA, alternate forms of anesthesia have been postulated. We aimed to evaluate the outcomes of URS under conscious sedation. METHODS: We completed a retrospective cohort study from November 2019 to June 2020 at a tertiary-level hospital. All URSs that were performed under urologist-directed conscious sedation were included. Our primary outcome was the ability to complete URS, defined as success rate. Secondary outcomes included: stone-free rate, intraoperative complication rate, hospital admission rate, and sedation requirement. Univariate- and multivariate-adjusted logistic regression analyses were employed. RESULTS: Ninety-nine URSs were included. Most (73/99, 73.7%) were performed for urolithiasis. The overall success rate was 83.8% (83/99), with 81.0% (34/42) intra-renal and 70.0% (16/23) proximal ureter success rates. The stone-free rate was 80.8% (59/73). No intraoperative complications nor hospital admissions were reported. The mean amount of sedation required was 3 mg (interquartile range [IQR] 2-4] of midazolam and 100 µg (100-150) of fentanyl. On multivariate analysis, midazolam was significantly associated with increased success (odds ratio 2.496, 95% confidence interval 1.057-5.892, p=0.037). CONCLUSIONS: We have shown that proximal and intrarenal URS under conscious sedation is safe and effective. We were limited by our lack of followup, small sample size, selection bias to chose healthy patients, and lack of patient tolerability data. Patients and healthcare systems may benefit from implementing this innovation more broadly.

Diagnostic Accuracy of Calculated Tumor Volumes and Apparent Diffusion Coefficient Values in Predicting Endometrial Cancer Grade.

Background: Magnetic resonance imaging (MRI) has been shown to be an accurate imaging technique for the preoperative assessment of local staging of endometrial cancer and for evaluating the depth of myometrial invasion. Materials and Methods: This was a single-center retrospective study performed on patients with histopathologically proven endometrial carcinoma who underwent an MRI examination of the pelvis between October 2017 and May 2020. Results: In the present analysis, mean apparent diffusion coefficient (ADC) values for each histologic grade were 0.72 ± 0.13 × 10-3 mm2/s (G1), 0.76 ± 0.17 × 10-3 mm2/s (G2), and 0.74 ± 0.12 × 10-3 mm2/s (G3), respectively, showing no significant correlation between ADC values and tumor grade (P = 0.73). Overall, ADC minimum was significant in differentiating grades of endometrial carcinoma (P = 0.02) with the ability to differentiate Grade I and II lesions (P = 0.01). A mean tumor volume of 25.2 cc could differentiate low-grade tumors (Grade I and Grade II) from high-grade tumors (Grade III) with a sensitivity and specificity of 88% and specificity of 89%. The tumor volume/uterine volume ratio (TV/UV) differentiates high-grade tumors from low-grade tumors (P < 0.001), however, no significant difference in the ratio was observed among Grade I and II lesions (P = 0.48). The area under the curve of tumor volume was 0.875 (95% confidence interval 0.0-1.00) (P = 0.001), indicating that tumor volume was an effective tool for distinguishing high-grade and low-grade endometrioid adenocarcinomas. The corresponding sensitivity and specificity were 88.0% and 89.0%, respectively. Conclusion: Preoperative noninvasive radiological assessment for tumor volume, TV/ UV or tumor volume/uterine volume is important surrogate markers for preoperative prognostication of endometrial carcinoma.

Aerosol Production with Surgical Instrumentation: Implications for Head and Neck Surgery in the COVID-19 Era.

Evaluating the aerosolization of droplets from surgical instruments to assess the implications of surgery in SARS-CoV-2 transmission for both patients and providers. Cadaver study. Outpatient surgery center. Aerosolized particles between 0.3 and 25 microns were measured. Instruments tested included monopolar cautery with and without suction, bipolar cautery, a bipolar vessel sealing device, and tissue scissors. Each trial was compared to a background reading. Monopolar cautery without suction, Ligasure used continuously and Bipolar cautery produced the most aerosols. Monopolar cautery with simultaneous suction produced no detectable aerosols. Ligasure used for a single cycle produced notably fewer aerosols than during continuous use. Most aerosols produced were < 5 microns. These data support n95 use during surgical management of the upper aerodigestive tract, as well as the use of suction in the surgical field.

Canadian provider perspectives on Collagenase Clostridium histolyticum for the treatment of Peyronie's disease and the impact of its discontinuation.

Intralesional Collagenase Clostridium histolyticum (CCh) was the first non-surgical therapy approved for Peyronie's disease (PD). However, CCh's cost and poor market uptake has led to its discontinuation in Europe and Canada. In Canada, Xiaflex® is the trade name for CCh and it is produced by Paladin Labs Inc, an operating company of Endo International. The paper aims to better understand Canadian CCh providers' perspectives regarding its treatment efficacy and the potential impact of its discontinuation. All Xiaflex®-approved Canadian providers were asked to complete an anonymous 21-question survey using an online platform. Analysis consisted of descriptive statistics. Outcomes of interest included previous experience with CCh, protocols utilized, experience with insurance coverage, clinical and patient-reported outcomes, and provider perspectives on the discontinuation of CCh. Overall response rate was 48.3% (29/60). A total of 89% of respondents were male, 61% were in practice more than 10 years, 32% were in an academic practice, and 46% had completed an Andrology/Sexual Medicine fellowship. A total of 93% of respondents felt that CCh was superior to other intralesional therapies for PD. In all, 86% reported a patient satisfaction rate of at least 50%, and the majority (75%) saw a clinically meaningful response. Only 7% expressed difficulty obtaining insurance coverage, with many providers (71%) achieving an insurance approval rate between 75 and 100%. Only 54% of respondents reported that they would continue treating PD in light of CCh's discontinuation, and 96% felt that CCh's discontinuation represents a loss to Canadian patients. In light of CCh's discontinuation, most (79%) are now more likely to offer surgical treatment. In conclusion, most CCh providers found CCh to be effective and were dismayed by its discontinuation. The survey demonstrated that due to the withdrawal of CCh from Canada, physicians' abilities to offer effective medical therapy may become limited, with more providers offering surgical options for PD.

Prevalence of Molecular Subtypes in Operated Cases of Breast Cancer and Its Clinicopathological Correlation: A Single Institute Study from a Tertiary Cancer Centre in North India.

Breast cancer has emerged as a major health problem among women in India. There are few Indian studies which have looked at prevalence of molecular subtypes of breast cancer in Indian population. The primary objective of our study was to find out the prevalence of various molecular subtypes in operated cases of breast cancer patients presenting to us. Three hundred sixty patients who were operated in our department were analysed. Clinicopathological features of all cases were recorded. Classification into various molecular subtypes was done using St. Gallen 2013 criteria. Luminal B HER2 negative was the predominant molecular subtype in our study population constituting 30.3% of patients. The percentage of aggressive subtypes, viz. triple negative breast cancer and HER2 enriched, were 21.7% and 11.4% respectively. Only 19.4% of patients in our study population had tumour size ≤ 2 cm with nodes being positive in 56.9% of our patients at presentation. Data from our study and other studies published from India show that the two most aggressive subtypes of, viz. triple negative breast cancer and HER2 enriched, may be more prevalent in our population as compared to western population.

Prognostic factor for recurrence in esophagus cancer patients who underwent surgery for curative intent: A single-institution analysis.

OBJECTIVE: The purpose of this study is to analyze predisposing factors for a higher risk of recurrence in esophageal cancer patient who underwent surgery for curative intent and to do survival analysis of prognostic factors. MATERIALS AND METHODS: Between February 2018 and March 2020, we retrospectively identified 28 cases staged T1b to T4a managed electively at our institute as per multidisciplinary management plan. Demographic, clinical, radiological, operative, histopathological parameters, upfront surgery done or not, type of preoperative, and adjuvant treatment used and whether neoadjuvant or adjuvant therapy was planned along with waiting time for surgery, were assessed as potential risk factors. End point of study was to find potential risk factors for recurrence and to do their subgroup survival analysis. RESULTS: The recurrence rate in our study was 25% with a mean follow-up of 24 months. The median time of recurrence was 8.5 months, all recurrence occurred within 1 year. Overall DFS at 2 years was 72%. On univariate analysis, following prognostic factors were associated with high risk of recurrence, male sex X2 (1) =4.42, p = 0.035; histology subtype of adenocarcinoma X2 (1) = 7.07, p = 0.008; margin positive X2 (1) =3.76, p = 0.05; presence of lymph vascular invasion (LVI) X2 (1) =7.88, p = 0.005; presence of perineural invasion (PNI) X2 (1) =5.97, p = 0.015; postoperative T size >4 cm X2 (1) =3.86, p = 0.049; and nodal positivity X2 (3) =13.47, p = 0.004. CONCLUSIONS: Male sex, adenocarcinoma histological subtype, positive resected margin, presence of LVI and PNI, postoperative T size >4 cm, and high postoperative nodal positivity and whether neoadjuvant versus adjuvant therapy given (on K. M analysis) were the identified predictors of recurrence which compromised DFS.

Thrombocytopenia in COVID-19: Focused Summary of Current Understanding of Mechanisms and Clinical Implications.

Thrombocytopenia is noted in corona virus disease-2019 (COVID-19) with a prevalence of 5% to 41%, and has been observed to be associated with inferior outcomes. The pathogenesis of thrombocytopenia in COVID-19 is unique and differs from other viral syndromes in terms of clinical presentation and causative mechanisms. Platelets act as both targets and the initial defense against severe acute respiratory syndrome-coronavirus 2 and work in concert with the underlying thrombophilic mechanisms to modulate the final disease phenotype. Understanding these mechanisms may possibly allow targeting of a key component of COVID-19 pathogenesis. We provide a focused review of the current mechanisms implicated in development of thrombocytopenia in COVID-19 and therapeutic implications of the same.

Risk Factors of Biochemical Failure in Locally Advanced Carcinoma Prostate Treated With Definitive External Beam Radiotherapy and Androgen Deprivation Therapy: Experience From Tertiary Care Center in North India.

Background Locally advanced prostate cancer (LACAP), despite external beam radiotherapy (EBRT) along with antiandrogen therapy (ADT) has risk of prostate-specific antigen (PSA) progression. Furthermore, number of studies have emphasized on different prognostic factors. The purpose of our study is to analyze risk factors for biochemical failure (BF) in these patients treated at our institute. Methods Our study is a single-institution retrospective observational done at a tertiary care center in North India. Between January 2018 and December 2020, we retrospectively identified 34 patients managed at our institute as per multidisciplinary board (MBD). Demographic, clinical, radiological, pathological and treatment-related parameters were assessed as potential risk factors. End-point of the study was to find significant risk factors for BF. Statistical analysis was done on SPSS, version 20 (IBM Corp., Armonk, NY). Results All eligible patients received EBRT with ADT as per institution policy. Mean follow-up period was 20 months during which two (5.9%) patients had BF at a mean of 30 months after EBRT. Four-year PSA-progression-free survival rate was 73%. On univariate analysis, prognostic factors associated with high risk of BF were Gleason score and clinical T stage. Conclusion In summary, prognostic factors for high risk of BF leading to clinical progression are Gleason score 9 or 10 and clinical T3b stage.
