Growth performance, meat quality and hematological parameters of broiler chickens fed safflower seed.

The aim of the current study was to determine the effects of dietary supplementation of safflower seed (SS) on the growth performance and hematological parameters of broiler birds along with the physicochemical, textural and sensory attributes of chicken meat. A total of 200 male chickens (7-days-old) were distributed into 5 groups (40 chickens in each) with 5 replicates of 8 chicks in a 42-day experiment. Each group was allocated to one of 5 dietary treatments, i.e., 0, 2.5, 5, 7.5, and 10% SS. The experimental diets were formulated for starter (7 to 21 days) and finisher (22 to 42 days) phases. Inclusion of SS in the diet improved growth performances in treatment groups between 7 and 42 days. The highest and lowest body weights were observed at the 5% SS and 0% SS levels, respectively. The physicochemical attributes of breast and thigh meat were found (P > 0.05) except for crude fat. The crude fat was significantly (P < 0.05) increased with increasing levels of SS in the diet. The inclusion of SS in the diet did not negatively impact the textural properties, i.e., hardness, cohesiveness, springiness, gumminess, chewiness, and shear force of breast and thigh meat. There was no significant difference in the sensory parameters of cooked chicken meat with increasing levels of SS in the diet. The results demonstrated a significant (P < 0.01) improvement in hematological parameters in the blood samples of broiler chickens fed diet supplemented with various levels of SS for five weeks. These findings suggest that, SS may be used as an oil seed for broiler chicken feed.

Comparing T2-T3 staging of penile cancer according to the American Joint Committee on cancer 8th edition with two modified staging systems in predicting survival outcome: A single-center experience.

Introduction: Penile cancer is a rare malignancy of the genitourinary tract. We aimed to validate the recent changes in the T2 and T3 stages of penile cancer in the American Joint Committee on Cancer (AJCC) 8th edition and to compare its predictive ability with two other modified staging systems for survival outcomes. Methods: This is a retrospective study of patients diagnosed with penile cancer from June 2015 to March 2020. The AJCC 8th edition and two other newly proposed systems by Li et al. and Sali et al. were used for staging the tumor. All variables were categorized and correlated with lymph node (LN) metastases and overall survival (OS). Results: Fifty-four patients were eligible for this study. The mean age was 58 years (range 46-72 years). The tumor stage (P = 0.016), clinical LN stage (P = 0.001), the involvement of the spongiosa (P = 0.015) and the cavernosa (P = 0.002), lymphovascular invasion (LVI) (P = 0.000), and PNI (P = 0.021) were found to be the significant predictors of LN metastases. When the 5 year OS was compared between the T2 and T3 stages of the AJCC 8th edition, Li staging and the Sali staging systems, it was 91% and 50.1% (P = 0.001), 97.5% and 10.3% (P = 0.000), 94.4% and 14.7% (P = 0.000), respectively. The presence of LVI (P = 0.001) was the most significant independent predictor of OS. Conclusions: The recent changes in the AJCC 8th edition pertaining to the T2-T3 stage are relevant, although the other two newly proposed staging systems were more precise in predicting the survival outcomes.

Upper tract transitional cell carcinoma clinically mimicking inflammatory renal pathology: A report of three cases.

Upper tract urothelial carcinoma (UTUC) of the renal pelvis and the ureter is incidentally detected in a small proportion of cases. However, the majority of UTUC cases present with hematuria, flank pain, and clot colic. Typical imaging features include hydronephrosis of the kidney (s) due to obstruction by the mass with a soft-tissue lesion that typically shows low-grade enhancement with or without a filling defect. Rarely, such a tumor may present with signs and symptoms mimicking an inflammatory or infective pathology of the kidney and is diagnosed only on biopsy or on nephrectomy. We present three such patients and cite another similar case we have published earlier. All three of these patients presented with signs and symptoms of an obstructed infected kidney with long-standing renal calculi and a forgotten DJ stent in one instance. Nephrectomy for the presumed infected kidney in all three cases revealed high-grade UTUC. In patients presenting with equivocal findings on cross-sectional imaging with a history of renal calculi or foreign bodies, we should have a high index of suspicion for malignancy.

Role of positron emission tomography/computed tomography in the evaluation of renal cell carcinoma.

INTRODUCTION: Positron emission tomography (PET) is not a standard recommendation in most of the major guidelines for the evaluation of renal cell carcinoma (RCC). Earlier studies evaluating PET scan in patients with RCC have provided discordant results. However, with the advent of newer hybrid PET/computed tomography (CT) scanning systems, this modality has shown increased efficacy in the evaluation of primary renal masses along with the detection of extrarenal metastases, restaging recurrent RCC, and also in monitoring response to targeted therapy. We performed a systematic review of the existing literature on the role of PET scan in the evaluation of RCC. METHODOLOGY: We systematically searched the databases of PubMed/Medline, Embase, and Google Scholar to identify studies on the use of PET scan in RCC. Using Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, 94 full-text articles were selected, of which 54 relevant articles were then reviewed, after a consensus by the authors. RESULTS: Several studies have shown similar sensitivity and specificity of fluoro-2-deoxy-2-d-glucose-PET (FDG-PET) scan as compared to conventional CT scan for the initial diagnosis of RCC, and an improved sensitivity and specificity for the detection of metastases and recurrences following curative therapy. The PET scan may also play a role in predicting the initial tumor biology and pathology and predicting the prognosis as well as the response to therapy. CONCLUSION: The current guidelines do not recommend PET scan in the staging armamentarium of RCCs. However, FDG-PET scan is as efficacious, if not better than conventional imaging alone, in the evaluation of the primary and metastatic RCC, as well as in evaluating the response to therapy, due to its ability to pick up areas of increased metabolic activity early on. Newer tracers such as Ga68 prostate specific membrane antigen-labeled ligands may help in opening up newer avenues of theragnostics.

Experience with management of renal cell carcinoma with inferior vena cava/right atrial tumor thrombus.

INTRODUCTION: We aimed to present our experience in managing renal cell carcinoma (RCC) with inferior vena cava (IVC) thrombus. METHODS: Records of all patients aged 18 years and older, with a diagnosis of primary renal masses with IVC thrombus, presenting to our institute from January 2012 to August 2020 were retrospectively reviewed. Patients with tumor thrombus limited only to renal vein were excluded from the analysis. Their hospital course and outcomes were recorded and evaluated for predictors of survival. RESULTS: During the study period, we treated 61 patients with a renal mass and concurrent IVC thrombus and 56 of these underwent surgery. 7 of them had level III and 6 had level IV thrombus. A total of six patients received neoadjuvant tyrosine kinase inhibitor (TKI) therapy and all of them showed a decrease in size and level of tumor thrombus and cardiopulmonary bypass was safely avoided. Fourteen patients had distant metastasis and underwent cytoreductive surgery and of these 12 patients received TKI therapy after surgery with a mean survival of 26.8 months. The overall survival at 2 and 5 years of nonmetastatic group was 81.1% and 47.5% respectively and in metastatic group was 35.1% and 0%, respectively. Poor performance status, distant metastasis, higher T stage, higher thrombus levels, and positive surgical margins were all predictors of decreased survival. CONCLUSIONS: Complete surgical resection in both nonmetastatic and metastatic RCC with IVC thrombus has long-term survival benefits. Neoadjuvant TKI therapy, with adequate preoperative planning, helps in decreasing the size of the thrombus and in safely avoiding bypass in level III and IV IVC thrombi.

Radical cystectomy and W-shaped ileal orthotopic neobladder reconstruction with serosa-lined tunneled ureteroileal anastomoses: A critical analysis of the short-term voiding patterns and urodynamic and functional outcomes.

INTRODUCTION: We present the short-term voiding patterns and functional and urodynamic outcomes of W-shaped ileal orthotopic neobladder (ONB) following radical cystectomy (RC). MATERIALS AND METHODS: Forty-one patients who underwent RC and W-shaped ONB creation between July 2015 and January 2018 were enrolled. Data were analyzed in terms of voiding patterns, urodynamic findings, and functional outcomes at 6 months after surgery. Pouch-related quality of life (QoL) was assessed using European Organization for Research and Treatment of Cancer (EORTC) Generic (QLQ C30), Bladder Cancer-Specific Instruments (QLQ BM30), and IONB-Patient-Reported Outcome (IONB-PRO). RESULTS: The mean length of follow-up was 19.4 months. At first follow-up, three patients had developed acidosis and rising serum creatinine, and one of them required temporary hemodialysis. One patient developed urethral-pouch anastomotic stricture, which required bladder neck incision. Balloon dilatation was performed for ureteroileal anastomotic stricture and mesh repair for incisional hernia was required in one patient each. Upper tract changes were observed in two patients. During the first and second follow-up, maximum flow rate, voided volume, and postvoid residual urine were 12 ± 4.7 mL/s, 212 ± 120 mL, and 72 + 81 mL and 14.7 ± 5.3 mL/s, 254 ± 168 mL, and 123.7 ± 42.5 mL, respectively. The mean pouch capacity and compliance were 436 ± 103.5 mL and 50.6 ± 17.8 mL/cm H2O. No patient required clean intermittent catheterization for bladder emptying. In EORTC QLQ-C30 questionnaire, the "Cognitive" domain had the highest and "global QoL" domain had the lowest level of functional scores. "Nausea and vomiting and abdominal bloating and flatulence" domain had the lowest level and "financial difficulties and urinary symptoms" had the highest level of symptomatology in EORTC QLQ questionnaire. The IONB-PRO questionnaire showed the highest level of functioning in "relation life" and the lowest level in "emotional life" domain. CONCLUSION: The Ghoneim pouch has a low complication rate with near-normal voiding patterns with an acceptable QoL impairment.

Safety and outcome of percutaneous nephrolithotomy in patients with solitary kidney: A tertiary care center experience.

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) for stones in solitary kidney poses a significant challenge and potential threat for acute kidney injury or progression of chronic kidney disease (CKD). We present our experience of PCNL in solitary functioning kidney (SFK) to evaluate the safety, efficacy, and postoperative complications and highlight the differences between these outcomes with respect to the stage of CKD. METHODS: We carried out a retrospective study of patients with SFK, who underwent PCNL at our center from April 2010 to March 2018. Patients who had a minimum of 6 months of follow-up were included. Patients were classified into CKD groups based on the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative. Group 1 included Stages 1, 2, and 3A and Group 2 included Stages 3B, 4, and 5. Postoperative complications and stone-free rate were recorded and graded according to the Clavien-Dindo classification and compared between the two groups. RESULTS: We had a total of 128 patients (Group 1 - 84 and Group 2 - 44). Stone-free rate after the first PCNL was higher in Group 1 as compared to Group 2 (88.1% [n = 74] vs. 50% [n = 22], P = 0.02). Overall, 48 patients (37.5%) had postoperative complications, but most were minor. Clavien Grade 1 and 2 complications were seen in 34 patients (Group 1, n = 18 and Group 2, n = 16, P = 0.069), whereas Grade 3 and 4 complications were seen in 14 patients (Group 1, n = 2 and Group 2, n = 12, P < 0.001), respectively. Need for postoperative (number of sessions) dialysis was seen with increased frequency in patients with higher chronic kidney stages (Group 1 vs. Group 2; 6 vs. 22 sessions, P < 0.001). CONCLUSION: PCNL in SFK is safe, with satisfactory outcome, but patients with advanced CKD stage have higher risk of complications including need for dialysis and may require multiple sessions for complete stone clearance. Hence, they should be managed at high output tertiary centers.

An Analysis of the Diagnostic Performance of Tc-99m PSMA SSPECT/CT in Biochemically Recurrent Prostate Cancer Compared with Ga-68 PSMA PET/CT: A Single-center, Prospective Study.

Objective: Biochemical recurrence (BCR) after initial management of Prostate Carcinoma (PC) is frequent. Subsequent interventions rely on disease burden and metastasis distribution. 68Ga prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) is an excellent imaging modality in BCR. However, 68Ga is radionuclide generator produced and has restricted availability. 99mTc-labeled PSMA could be a potential cost-effective alternative. We compared the performance of 99mTc-PSMA single-photon emission CT (SPECT)/CT and 68Ga-PSMA PET/CT in BCR with a serum prostate surface antigen (PSA) level of <20 ng/mL. Materials and Methods: The prospective study included 25 patients with BCR and at least one lesion on a 68Ga-PSMA PET/CT. All patients underwent 99 mTc-PSMA SPECT/CT, and disease distribution and metastatic burden were compared with 68Ga-PSMA PET/CT. The maximum standard uptake value (SUVmax) and the tumor-to-background ratio (TBR) were computed and analyzed. Results: The mean age and serum PSA (SPSA) were 69.72 ± 6.69 years and 5.65 ± 6.07 ng/mL. Eleven patients (44%) had SPSA ≤2 ng/mL. Recurrent sites were noted in the prostate (19, 76%), prostatic bed (3, 12%), and pelvis lymph nodes (LNs) (13, 52%). Distant metastasis to bones (13, 52%), lungs (5, 20%), and retroperitoneal LNs (2, 8%) were noted. Both modalities were concordant for the recurrent disease at the prostate, prostatic bed, bone, and lung lesions. 99mTc-PSMA could localize pelvis LNs in most patients (10/13, 76.9%). The site-specific sensitivity and specificity between the two modalities were not significantly different (P > 0.05). TBR shows excellent correlation with SUVmax (0.783, P < 0.001). Four (16%) patients were understaged with 99mTc-PSMA due to the nonvisualization of the subcentimeter size LNs. No patient with systemic metastases was understaged. Conclusions: 99mTc-PSMA SPECT/CT has good concordance with 68Ga-PSMA PET/CT in BCR, even at low PSA levels. However, it may miss a few subcentimeter LNs due to lower resolution. 99mTc-PSMA SPECT/CT could be a simple, cost-effective, and readily available imaging alternative to PET/CT.

Prevalence of non-communicable chronic diseases in rural India amongst peri- and post-menopausal women: Can artificial intelligence help in early identification?

AIMS: To identify peri- and post-menopausal women at risk of non-communicable diseases in rural India and to assess their prevalence amongst these groups via the use of artificial intelligence. SETTINGS AND DESIGN: An observational study conducted by the Indian Menopause Society in collaboration with the Government of Maharashtra. The study included rural women residents of three villages in the Latur district of Maharashtra, India. MATERIALS AND METHODS: Accredited social health activist workers identified 400 peri- and post-menopausal women aged 45-60 years. Specific symptoms able to predict the presence of a non-communicable disease were identified through the use of artificial intelligence. STATISTICAL ANALYSIS USED: Descriptive statistics and predictive network charts analysis. RESULTS: The mean age of 316 women included in the analysis was 50.4 years and the majority of them were illiterate (68 %). The prevalence of dyslipidaemia, osteopenia, diabetes mellitus, obesity and hypertension were 58 %, 50 %, 25 %, 25 %, and 20 % respectively. None of their symptoms or laboratory reports could be significantly correlated directly with any of these non-communicable diseases. Hence, we used a cluster of symptoms to suggest the presence of hypertension, diabetes mellitus, osteoporosis and hypothyroidism via predictive network analysis charts. CONCLUSIONS: Screening of at-risk women can be done using an artificial intelligence-based screening tool for early diagnosis, timely referral and treatment of non-communicable diseases with the support of community health workers.

Primary Renal Well-Differentiated Neuroendocrine Tumors: Analyis of Six Cases from a Tertiary Care Center in North India with Review of Literature.

Well-differentiated renal neuroendocrine tumors are rare tumors. As their biologic behavior is not fully known, there is a need to know more about these cases. We performed a retrospective chart review of all the cases diagnosed with renal neuroendocrine tumors from January 2016 to December 2020 (five years) in order to understand their clinical features, morphological characteristics and outcome. We included six cases with mean age of 46.2 years (4 males) in our study. All patients underwent radical nephrectomy. Histologically all showed tumor disposed in nests and trabeculae and majority of the tumors belonged to well-differentiated neuroendocrine tumor Grade 1 (WHO criteria of gastoroenteropancreatic neuroendocrine neoplasms). Lymph node metastasis was seen in two cases at the time of clinical presentation. All the tumors were diffusely positive for neuroendocrine tumor markers (synaptophysin, chromogranin, NSE, CD56). Follow-up data was available in all cases with an average follow-up of two years and neither has shown evidence of metastasis or relapse till last follow-up. Role of morphological patterns and immunohistochemical markers is highlighted with the importance of including Ki-67 index in grading them to better understand their outcome.

Is systematic prostate biopsy an overkill in metastatic prostate carcinoma ? A prospective validation.

PURPOSE: To assess the efficacy of 2-core prostate biopsy in advanced prostate cancer patients. This included a retrospective analysis of 12-core prostate biopsies and a prospective validation that a reduced number of cores are sufficient for histopathological diagnosis. METHODS: The first phase analyzed retrospective data from 12-core prostate biopsies between January 2013 and 2018. In the second phase, from January 2018 to January 2022, in a prospective setting, patients with PSA > 75 ng/dl underwent bone scans first. Those with positive bone scans underwent a 2-core biopsy. Cancer detection rate and complications were analyzed to validate the findings of the first phase. RESULTS: In the retrospective analysis, the number of positive cores in metastatic disease was 12 in 93 (73.8%), 11 in 14 (11.1%), and 10 in 7 (5.6%) patients. Using probability analysis, 94% of patients with metastasis could be detected with a single core and 97.8% with a 2-core biopsy. In the prospective analysis, 52 patients with PSA > 75 were enrolled. 3/52 (5.7%) patients had a negative bone scan. 49 were assigned for 2-core biopsy, out of which 48 (97.9%) had a positive result. One patient underwent a repeat 12-core biopsy. The prospective cohort's complications (p = 0.003) and pain score (p = 0.03) were lower compared to patients who underwent standard 12-core biopsies during phase one of the study period. CONCLUSION: A 2-core biopsy is adequate in almost all patients with metastatic prostate cancer with PSA > 75, and this avoids excess complications and morbidity associated with a systematic 12-core prostate biopsy.

Ureterovesical Leak Following Renal Transplant and Effects of Acute Rejection and Antirejection Therapy: A Nested Case-Control Analysis and Outcome of 1102 Consecutive Renal Transplant Recipients.

OBJECTIVES: Studies on nontechnical risk factors for ureterovesical leak after renal transplant are scarce. This study aimed to report the possible pre- and postoperative risk factors and the role of acute rejection and antirejection therapies for urine leak after transplant and its effect on graft and patient survival. MATERIALS AND METHODS: We conducted a retrospective analysis of 13 patients (1.17%) with urine leak (case group) and 52 patients without leak (control group) (case-to-control ratio of 1:4) from 1102 living related (first degree) renal transplant recipients seen between January 2012 and December 2021. We analyzed demographic and clinical details and biochemical and outcome parameters using a nested case-control design. RESULTS: Cases were olderthan controls (P = .018), were more ABO incompatible (P = .009), and had more 6/6 HLA mismatch transplants (P = .047). Donors of cases were older than donors of controls (P = .049). The rate of postoperative hypoalbuminemia was greaterin the case group (P = .050). Rates of acute rejection (P = .012) and plasmapheresis (P = .003) were greaterin the case group than in the control group. On multivariate logistic regression analysis, recipient age, 6/6 HLA mismatch, and plasmapheresis were found to independently associated with urine leak. None ofthe patient required surgical repair, as all responded to conservative therapy. Urine leak did not affect graft outcomes (P = .324), but overall survival was less in cases than in controls. CONCLUSIONS: Nontechnical risk factors that cause posttransplant ureteric leak include older donor and recipient age and ABO incompatible and 6/6 HLA mismatch transplants. Acute rejection and plasmapheresis predispose leak, and an indwelling double J stent can allow adequate healing of the anastomosis. High index of suspicion and prompt management are imperative to preserve graft and patient outcome.

Assessment of determining factors for severity of NeoCOVIDiabetes in India: A pan India multicentric retrospective study.

BACKGROUND AND AIMS: There is a bidirectional relationship between COVID-19 and diabetes. The primary objective of this study was to estimate the prevalence of patients newly detected to have diabetes (NDD) who recovered from COVID-19 in India whilst comparing NDD with patients without diabetes (ND) and those who have known to have diabetes (KD) in terms of glycemic status pre- and post-COVID with disease severity. MATERIALS & METHODOLOGY: There were 2212 participants enrolled from 15 sites, with 1630 active participants after the respective execution of selection criteria. Data collection was done using a specialized Case Record Form (CRF). Planned statistical analysis and descriptive statistics were concluded for significance between patient groups on various parameters. RESULT: The differences in age between the study groups were statistically significant. The average blood glucose at COVID-19 onset was significantly higher in KD than in NDD. Significantly more proportion of NDD (83%) had been hospitalized for COVID management when compared to KD (45%) and ND (55%). The NDD group received higher doses of steroids than the other two groups. On average, patients in the NDD group who received at least one vaccination (one dose or two doses) had a higher High-Resolution Computed Tomography (HRCT) score. Patients who had not been vaccinated in ND and KD groups experienced a higher HRCT score. CONCLUSION: Prospective metabolism studies in post-acute COVID-19 will be required to understand the etiology, prognosis, and treatment opportunities.

Preputial/penile skin flap, as a dorsal onlay or tubularized flap: a versatile substitute for complex anterior urethral stricture.

UNLABELLED: Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? For long complex anterior urethral stricture augmentation urethroplasty is considered the standard procedure but the best substitute material is still to be ascertained. Preputial/penile skin is a very good substitute especially when used as a dorsal onlay. It demonstrates exceptional functional and cosmetic results even in patients with unsuitable oral mucosa. OBJECTIVE: • To present our experience of single-stage reconstruction of urethral stricture with preputial/penile skin flap, as a dorsal onlay flap (DOF) where there is an adequate urethral plate and as a tubularized flap (TF) where there is a compromised urethral plate, in cases of complex anterior urethral strictures. MATERIALS AND METHODS: • We retrospectively reviewed 144 patients, who underwent single-stage repair of pendular /bulbar urethral strictures with preputial/penile flap as either a DOF or a TF, between January 2001 and December 2008. • Patients were divided into three groups: Group 1 consisted of patients who underwent transverse preputial DOF; Group 2 consisted of those who underwent tube urethroplasty; and Group 3 consisted of those patients who were circumcised and for whom the penile skin was used as a DOF (circumpenile flap). • Patients were followed up by physical examination, retrograde urethrography, uroflowmetry and post-void residual urine measurement. RESULTS: • The mean follow-up was 40.1 months (range 36-84 months). • The primary success rates at 1 year follow-up were 90, 85 and 93.3% for Groups1, 2 and 3, respectively, and at 3-years follow-up they were 85, 75 and 86.7%, respectively. • Half of the recurrences were successfully managed with a single visual internal urethrotomy or dilatation. • The secondary success rate was defined as recurrent stricture managed by a single endoscopic procedure and was 5, 10 and 6.8% in Groups 1, 2 and 3, respectively. The overall success rate was 90.85 and 93.3%, respectively. • A total of 75% of the patients in the study completed 60 months of follow-up with no additional recurrence. CONCLUSIONS: • A preputial/penile flap for complex anterior urethral stricture is a good treatment option, with results similar to other techniques, has acceptable donor site morbidity and is effective even in circumcised patients and for those patients with unsuitable oral mucosa. • A DOF is less likely to lead to diverticula formation and post-void dribbling. TFs have a higher failure rate than DOFs but, when combined judiciously with secondary endoscopic procedures, can provide good results.

Primary mucinous cell adenocarcinoma of female urethra.

Primary adenocarcinoma of the female urethra is a rare entity. Its incidence increases with age with the highest rate in women aged more than 65 years. Adenocarcinoma of the urethra is more common among women than men and is associated with a relatively poor prognosis. We report a case of primary adenocarcinoma of the urethra and review the literature with emphasis on the diagnosis, management and outcome of this rare tumour.

An adaptive particle swarm optimization-based hybrid long short-term memory model for stock price time series forecasting.

In this paper, we presented a long short-term memory (LSTM) network and adaptive particle swarm optimization (PSO)-based hybrid deep learning model for forecasting the stock price of three major stock indices such as Sensex, S&P 500, and Nifty 50 for short term and long term. Although the LSTM can handle uncertain, sequential, and nonlinear data, the biggest challenge in it is optimizing its weights and bias. The back-propagation through time algorithm has a drawback to overfit the data and being stuck in local minima. Thus, we proposed PSO-based hybrid deep learning model for evolving the initial weights of LSTM and fully connected layer (FCL). Furthermore, we introduced an adaptive approach for improving the inertia coefficient of PSO using the velocity of particles. The proposed method is an aggregation of adaptive PSO and Adam optimizer for training the LSTM. The adaptive PSO attempts to evolve the initial weights in different layers of the LSTM network and FCL. This research also compares the forecasting efficacy of the proposed method to the genetic algorithm (GA)-based hybrid LSTM model, the Elman neural network (ENN), and standard LSTM. Experimental findings demonstrate that the suggested model is successful in achieving the optimum initial weights and bias of the LSTM and FC layers, as well as superior forecasting accuracy.

Percutaneous nephrostomy in Ureteropelvic junction obstruction with poorly functioning kidney: Is it still pertinent in adults?

OBJECTIVE: To determine the pertinence of percutaneous nephrostomy drainage in adult patients of primary ureteropelvic junction obstruction with poorly functioning kidneys (<20% split renal function). MATERIAL AND METHODS: Clinical records of all patients with primary ureteropelvic junction obstruction with poorly functioning kidneys who underwent percutaneous nephrostomy drainage in our institute between February 2015 and January 2020 were retrospectively reviewed. The patients were divided into 4 groups according to their split renal function obtained from the Tc-99m ethylenedicysteine diuretic renogram. Group I consisted of all patients having split renal function ≤5%, group II with split renal function 6-10%, groupIII with split renal function 11-15%, and finally group IV with split renal function 16-20%. Those patients inwhom split renal function was improved by >10% and had daily percutaneous nephrostomy output >400 mL, underwent pyeloplasty and the rest underwent nephrectomy. RESULTS: Seventy-two patients were studied, out of which 5 were in group I, 20 in groups II and III each, and27 in group IV. The mean age of presentation was 34.4 ± 14 years. The split renal function improvement of>10% was seen in 55 patients (76.4%) after percutaneous nephrostomy drainage (P < .05). Pyeloplasty wasdone in 40 patients (55.6%) and nephrectomy was done in 32 patients (44.4%). CONCLUSION: In conclusion, we recommend the use of a Tc-99m ethylenedicysteine scan for estimation of split renal function during the initial presentation in every patient followed by reconstructive surgery if split renal function is above 15% and nephrectomy if it is below 5%. The trial of percutaneous nephrostomy is pertinent if split renal function is between 6% and 15%.

Vesicovaginal Fistula Repair by Transvaginal Route: Comparison of Resource Utilisation and Outcome with Literature Reported Population Matched Cohort of Patients Operated by Minimally Invasive Route.

Introduction and Objectives: VVF is conventionally repaired by open transvaginal or transabdominal routes. In last few decades, minimally invasive techniques (laparoscopic/robotic) for VVF repair have gained popularity. We have reported our experience of transvaginal vesicovaginal fistula (VVF) repair and compared it with the literature reported population matched cohort of VVF repair done by laparoscopic or robot-assisted techniques. Material and Methods: Intraoperative and post-operative parameters including aetiology of fistula, location, operative time, blood loss, major complications, hospital stay and success rate of 202 patients with simple VVF undergoing transvaginal repair at a tertiary care hospital from 1999 to 2019 were recorded. We also compared our transvaginal repair cohort (n = 202) with the literature reported cohort of 260 patients undergoing VVF repair by minimally invasive (laparoscopic and robot assisted) techniques in the systematic review by Miklos et al. Results: Most common aetiology of VVF in our series was post hysterectomy in 122 (60.39%) cases followed by trauma during emergency caesareans section in 80 (39.60%) cases. Transvaginal route had higher success rate than minimally invasive approach (99.50 vs. 96.50%, respectively). Mean operative time was lesser in transvaginal group than the minimally invasive group (63 ± 16 min vs. 161.56 ± 41.02 min, p < 0.01) with shorter mean hospital stay in transvaginal group (3 ± 1 days vs. 3.5 ± 1.16 days, respectively, p < 0.01). Mean estimated blood loss was significantly lesser in transvaginal repair (p < 0.01). 62% patients were sexually active at last follow-up. The cost of transvaginal VVF repair is significantly lower compared to repair by minimally invasive approach. Conclusion: Transvaginal VVF repair is comparable to minimally invasive approach in terms of post-operative outcomes and morbidity; however, transvaginal repair performs better in terms of cost and resource utilization.

Crossed unfused renal ectopia with pelviureteric junction obstruction associated with nephrolithiasis: a rare troublesome triad managed by robotic surgery.

We report a rare case of non-fused renal ectopia with pelviureteric junction obstruction and multiple pelvic and renal calculi thereby discussing vascular anatomy of the non-fused ectopic kidney along with robot assisted surgical management of this rare clinical entity which amounts for good preoperative workup for best surgical and clinical outcome.
