Evaluating Transperineal Prostate Biopsies Performed by a New Operator: A Prospective Clinical Audit at Dorset County Hospital.

Introduction The transperineal (TP) approach for prostate biopsy offers advantages such as a low risk of infection, the ability to target lesions in difficult locations, and a rapid acquisition of proficiency. This prospective clinical audit aims to evaluate the outcomes and patient experiences of TP prostate biopsies performed by a new operator to determine the feasibility of adopting the TP biopsy as the primary method for prostate evaluations. Methods The study included all patients who underwent a TP prostate biopsy from August 1 to September 30, 2022, at Dorset County Hospital National Health Service Foundation Trust. The operator, a member of the urology team, had recently begun performing these biopsies independently after completing a four-month supervised training program and receiving approval from two consulting trainers. The biopsy technique was evaluated based on diagnostic yield and patient experience, comparing pre-procedure imaging results with histology reports and analyzing patient-completed questionnaires. Results Among the 42 patients, the cancer detection rate was 79%. The highest core positivity rate was 100% in two patients (5%), with 90% in 11 patients (26%). Of the patients, 57% showed complete agreement between magnetic resonance imaging findings and histology. A questionnaire assessing patient experience received a 64% response rate. The most common pain score reported was 2 (on a scale of 0-10), noted in 25% of patients. Most reported mild lower urinary tract symptoms (88%) and mild hematuria (85%). Of the patients, 44% rated their overall satisfaction as 10 (on a scale of 0-10), and no urinary tract infections were reported. Conclusion The findings support the adoption of TP biopsy as the primary method for prostate biopsies due to its short learning curve, high diagnostic yield, and favorable patient satisfaction. Training for new operators should be encouraged to achieve this goal.

Evaluation of Biogenic Silver Nanoparticles Synthesized from Vegetable Waste.

Introduction: Vegetable waste has numerous essential values and can be used for various purposes. Unfortunately, it is often discarded worldwide due to a lack of awareness regarding its nutritional and practical significance. Even the nutrient-rich peels of fruits and vegetables are commonly wasted, despite their numerous useful applications. Utilizing vegetable waste to produce silver nanoparticles through green synthesis is an advantageous, economical, and environmentally friendly method for producing valuable products while addressing waste management concerns. The main emphasis of this study was to synthesize silver nanoparticles (AgNPs) by using vegetable waste from Solanum tuberosum (potato) and Coriander sativum (coriander). Methods: The stems of Coriander sativum and peels of Solanum tuberosum were used as extracts for the synthesis of AgNPs. The characterization of the synthesized AgNPs involved UV-spectroscopy, scanning electron microscopy (SEM), and X-ray diffraction (XRD). The phytochemical analysis was performed to analyze antimicrobial, cytotoxic, antidiabetic, antitumor, antioxidant, alpha-amylase, and protein inhibition activities. Results: The change in the color of the reaction mixture from yellowish green to brown following the addition of extracts to the silver nitrate solution confirmed nanoparticle synthesis. UV analysis has shown peaks in the range of 300-400nm. SEM confirmed the spherical and agglomerated morphology and size of 64nm for potato peel and 70nm for coriander stem. XRD confirmed the crystalline structure of silver nanoparticles. The phytochemical assays confirmed that silver nanoparticles had higher total phenolic and flavonoid contents. The biosynthesized silver nanoparticles showed promising antimicrobial, cytotoxic, antidiabetic, antitumor, and antioxidant properties and significant alpha-amylase and protein inhibition activities in comparison with the crude extracts. Conclusion: The bioactivity of the plant suggests that it could be a suitable option for therapeutic purposes. This study demonstrates a potential method for sustainable nanoparticle synthesis and the therapeutic applications of AgNPs derived from vegetable waste. By utilizing the potential of vegetable waste, we can contribute to both environmental sustainability and the development of innovative, valuable products in fields such as medicine, agriculture, and materials science. These findings encourage further research on agricultural byproducts, promoting environmentally friendly and economically advantageous research and development efforts.

Outcomes of Uretero-ileal Anastomosis in Bladder Cancer Cystectomies: Bricker vs. Wallace 1.

Background The two commonly used methods for uretero-ileal anastomosis (UIA) during radical cystectomy for muscle-invasive bladder cancer (MIBC) are the Bricker and Wallace 1 techniques. Published data on the incidence of strictures at anastomotic sites is limited. This study compares both anastomotic techniques in terms of uretero-ileal stricture (UIS) rates and the factors that govern it in the patient group. Material and methods Records of all patients presenting with bladder cancer who underwent radical cystectomy at the department of uro-oncology, Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH&RC) Lahore, Pakistan, from January 1, 2009, to December 31, 2018, were reviewed retrospectively, and all adult patients aged >18 years out of them were selected for the study. Results With a total of 116 patients, the mean age was 54.37 ± 11.16 and a male majority (83.6%). Urinary diversion using ileal conduit was performed in 70 (60.3%) patients and the rest of them i.e. 46 (39.7%) had neobladder formation. Amongst them, uretero-ileal anastomosis was constructed via Bricker and Wallace 1 in 73 (62.9%) patients and 43 (37.1%) patients respectively. Pelvic radiotherapy was received by 13 (11.2%) patients. Anastomotic stricture developed in 19 (16.4%) cases. A relatively similar proportion of stricture rate was found in Bricker and Wallace 1 technique (10% vs 13%). Body mass index (BMI) was found to be significantly higher in patients who developed UIS. Incidence of stricture formation was more on the left than right side i.e. 12 (63.2%) vs five (26.3%) while two (10.5%) patients developed bilateral strictures. Conclusion No significant difference in stricture formation was noted between Bricker and Wallace 1 technique. High BMI and anastomotic leaks were the contributory factors for this complication during our experience.

Comparison of Outcomes Between Radical Radiotherapy and Radical Cystectomy in Muscle Invasive Bladder Cancer in a Cancer Specialized Unit of a Developing Country.

Introduction Radical cystectomy (RC) is the current standard of care for treating muscle-invasive bladder cancer (MIBC), however bladder preservation by offering radical radiotherapy (RT) is gaining interest for improving the quality of life while maintaining a reasonable oncological outcome. In this study, we have compared outcomes of the two treatment options. Materials and methods This is a 10-year retrospective cohort study that included all patients who were treated for histologically proven muscle-invasive bladder cancer in the department of uro-oncology at Shaukat Khanum Memorial Cancer Hospital and Research Centre from January 2005 to January 2015. Data was analysed using Statistical Product and Service Solutions (SPSS), version 21 (IBM Corp., Armonk, NY). The primary end point of our study was to calculate the three- and five-year disease-free survival (DFS) and overall survival (OS). Results A total of 230 patients were included in the study with male gender predominating (88%). The mean and standard deviation for age was 58.32+11.128. Radical cystectomy was performed in 119 patients while 111 received RT. Clinically, 34% had stage 2 disease, while 66 % had stage 3 cancer. The median follow-up duration was 41 months (range: 2-155). During follow-up 57.4% of patients showed no recurrence. Local recurrence was found in 9.6% patients and distant metastasis in 32.2%. The three-year DFS of RC was 63% and that of RT was 57% while the five-year DFS for RC and RT were 60% and 49%, respectively (p=0.196). The three-year OS of RC was 64% and that for RT was 58%. On further analysis the five-year OS of RC was 53% and that for RT was 50% (p=0.98). Upon stage-based comparisons, we found no statistically significant difference between the three- and five-year DFS and OS of stage 2 and stage 3 when treated with either modality. Conclusion Most studies favor RC and consider it as the gold standard treatment for muscle-invasive bladder tumor treatment. The current study reveals that bladder preservation approach by chemo radiotherapy is a viable treatment option, having comparable oncological outcomes with patients receiving radical cystectomy, and can be offered to patients having muscle-invasive urothelial bladder cancer.

Oncological Outcomes of Non-Urothelial Bladder Cancers in a Specialized Cancer Hospital of a Developing Country.

Background Non-urothelial bladder cancers (NUBCs) constitute only 5% of all bladder cancers. Because of the scarcity of data, no standardized treatment can be offered to these patients. Surgical treatment can be offered to patients with localized disease; however, generally, the prognosis is unfavorable. Methodology Patients with histology-proven NUBC presenting to the Department of Uro-oncology, Shaukat Khanum Memorial Cancer Hospital and Research Center, Lahore, Pakistan, from January 2002 to July 2017 were identified and assessed retrospectively. Results A total of 20 patients with a median presenting age of 52 years (range: 34-87 years) were identified. Clinically, T3 was the commonest stage of presentation, i.e., in 11 (55%), whereas 1 (7.1%) patient had metastatic disease. Four types of NUBCs were identified: adenocarcinoma, squamous cell carcinoma, small cell carcinoma, and inflammatory myofibroblastic tumor. Most of the patients with adenocarcinoma were offered surgical treatment in the form of either partial (64.3%) or radical (28.6%) cystectomy. Two patients with small cell carcinoma and two of the three patients with SCC could only be offered palliative chemotherapy. During a median follow-up of 40 months, 14 (70%) patients developed disease progression or recurrence. All these patients succumbed to their disease during a median period of 37.5 months (range: 5-84 months). Furthermore, three- and five-year disease-free survival was 60% and 51%, respectively, and overall survival was 65% and 31%, respectively. Conclusions NUBC is a rare but aggressive disease that presents at an advanced stage in many cases. Treatment protocols are not uniform; therefore, further collaborative research is needed to improve survival outcomes.

Role of Maternal Education and Vaccination Coverage: Evidence From Pakistan Demographic and Health Survey.

The aim of this study was to examine the impact of maternal education on child immunization uptake in Pakistan, both at individual and community levels. Pakistan Demographic and Health Survey data were used for analysis. Multilevel logistic regression was used to access the individual- and community-level factors associated with childhood immunization coverage. Out of 6765 children 2659 (39.3%) were fully immunized. Parents education, access to media, and wealth status have positive while ethnicity and working status of mother have a negative impact on the immunization uptake. In the community with a high percentage of educated mothers, the odds of immunized children were high (odds ratio = 1.43, 95% confidence interval = 1.14-1.80) as compared with communities with lower percentage of educated mothers. Moreover, significant variation was found in the likelihood of full immunization across communities. Both community- and individual-level factors have substantial impact on children immunization status. There is a need of improvement in maternal education, poverty alleviation, and removal of rural-urban disparities.

Diethylstilbestrol in the Treatment of Castration-resistant Prostate Cancer: A Lower-middle-income Country Experience.

INTRODUCTION:  Prostate cancer is the second most common cancer and the fifth leading cause of death worldwide. Its metastatic stage is associated with considerable morbidity and may lead to death. In Pakistan, given the high levels of economic constraint, patients with castration-resistant metastatic prostate cancer can be treated with cost-effective medications like diethylstilbestrol (DES). OBJECTIVES:  The goal of this study was to assess the efficacy and adverse effects of DES when used in patients with castration-resistant prostate cancer (CRPC). MATERIALS AND METHODS:  From January 2011 to December 2016, all medical records of patients with a diagnosis of prostate cancer resistant to the effects of castration presenting at Shaukat Khanum Cancer Hospital and Research Centre, Lahore, were reviewed. All patients were treated with DES (2.5 mg) initially, but the dose was increased for some patients to 5 mg in combination with aspirin (75 mg). The patients were followed clinically with prostate-specific antigen (PSA) value assessment. The PSA response to treatment, time to disease progression, and adverse events were recorded and analyzed using IBM SPSS Statistics for Windows, Version 20.0 (IBM Corp., Armonk, NY). RESULTS: A total of 91 patients were included in the study, and the mean patient age was 66 ± 8 years. The median baseline PSA was 150 ng/mL (range: 56-626 ng/mL), and the median Gleason's score was eight. A total of 90.1% of patients had metastatic disease at the time of diagnosis. Hormonal ablation was provided with bilateral orchiectomy for 71 patients (78.0%), and luteinizing hormone-releasing hormone (LHRH) analog was provided for 20 patients (22.0%). With this treatment, the median time to PSA progression was 597 days. After DES treatment was started, 78 patients (87.7%) showed a PSA response, and median time to progression was 212 days. In 24 patients (26.4%), the PSA response was maintained for more than a year. The PSA response was quantified as a good response (i.e., ≥50% PSA drop) or as a partial response (i.e., <50% PSA drop). The good PSA response was observed in 56 patients (61.5%) with a median time to progression of 273 days, and 22 patients (24.2%) had a partial response maintained for 109 days. Thirteen patients (14.3%) did not respond to DES treatment. The median percent change in PSA was -55.52% (range: -99.9 to +422). Thromboembolic complication was observed in eight patients (8.7%) patients while two patients suffered from liver toxicity. CONCLUSION:  DES is an effective, economical, and relatively safe drug in patients with CRPC.

Outcomes of Nephron Sparing in a Specialist Cancer Hospital of a Developing Country.

Introduction Nephron-sparing surgery in the form of partial nephrectomy (PN) is currently considered the standard treatment for relatively small localized renal cell tumors. Objectives This study aimed to determine outcomes of PN regarding complications, recurrence, and survival rates at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan. Methods We assessed the data of patients older than 18 years undergoing PN from January 2010 to June 2017 who met our inclusion criteria. Data were analyzed using IBM SPSS Statistics for Windows, Version 20.0 (IBM Corp., Armonk, NY). Results A total of 35 patients were studied, with a male to female ratio of 2.5:1 with median age of 50 years. The median hospital stay was four days (range: 3-7), and the median RENAL (radius, exophytic/endophytic properties, nearness of tumor to the collecting system or sinus in millimeters, anterior/posterior location relative to polar lines) Score was five (range: 4-10). The most common pathological tumor stage was T1 (94%), and the median size was 3.5 cm. On histopathology, clear-cell carcinoma was the most common tumor (incidence, 71%). The median Fuhrman's grade was two. On final histopathology, four patients had positive margins. Among them, two patients showed a progressive deterioration in renal functions and were found to have residual disease six months later. Only one patient developed metastasis in the lung. Wound infection was observed in one patient while another had wound dehiscence. Urine leakage was noted in two patients. The median follow-up duration was 18 months (range: 3-84). Mean cancer-free survival was 78.6 months, and overall survival was 79.2 months. The projected three-year and five-year disease-free and overall survival was 96% and 94%, respectively. Conclusion PN is a viable option with excellent outcomes regarding the complication profile, recurrence-free, and overall survival in patients with relatively small localized renal tumors.

Socioeconomic Condition and Prevalence of Malaria Fever in Pakistani Children: Findings from a Community Health Survey.

OBJECTIVE: We assessed the prevalence of malarial fever and its association with demographic and socioeconomic factors in children <5 years of age. METHODS: Using the data of Pakistan Demographic and Health Survey (PDHS), the socioeconomic condition (SEC) was assessed by using a household wealth index as a proxy indicator, generated through principal component analysis. Two-stage sampling was used for selection of households, and multilevel logistic regression analysis was performed. RESULTS: The PDHS contains 10 935 children <5 years of age with valid information about malaria fever. In total, 36% (3930) children have malaria 2 weeks before the survey. A decreasing trend in prevalence of malaria fever was found with increasing SEC. Compared with SEC Quintile V, children of SEC Quintile I were more likely to get fever [adjusted odds ratio (AOR)=1.40 (1.15-1.69)] and of SEC Quintile II [AOR = 1.23 (1.03-1.45)]. CONCLUSION: SEC has a significant impact on the prevalence of malaria fever in the context of different regions in Pakistan.
