ABSTRACT
Purpose: An investigation of various convolutional neural network (CNN)-based deep learning algorithms was conducted to select the appropriate artificial intelligence (AI) model for calculating the diagnostic performance of bladder tumor classification on cystoscopy images, with the performance of the selected model to be compared against that of medical students and urologists. Methods: A total of 3,731 cystoscopic images that contained 2,191 tumor images were obtained from 543 bladder tumor cases and 219 normal cases were evaluated. A total of 17 CNN models were trained for tumor classification with various hyperparameters. The diagnostic performance of the selected AI model was compared with the results obtained from urologists and medical students by using the receiver operating characteristic (ROC) curve graph and metrics. Results: EfficientNetB0 was selected as the appropriate AI model. In the test results, EfficientNetB0 achieved a balanced accuracy of 81%, sensitivity of 88%, specificity of 74%, and an area under the curve (AUC) of 92%. In contrast, human-derived diagnostic statistics for the test data showed an average balanced accuracy of 75%, sensitivity of 94%, and specificity of 55%. Specifically, urologists had an average balanced accuracy of 91%, sensitivity of 95%, and specificity of 88%, while medical students had an average balanced accuracy of 69%, sensitivity of 94%, and specificity of 44%. Conclusions: Among the various AI models, we suggest that EfficientNetB0 is an appropriate AI classification model for determining the presence of bladder tumors in cystoscopic images. EfficientNetB0 showed the highest performance among several models and showed high accuracy and specificity compared to medical students. This AI technology will be helpful for less experienced urologists or nonurologists in making diagnoses. Image-based deep learning classifies bladder cancer using cystoscopy images and shows promise for generalized applications in biomedical image analysis and clinical decision making.
ABSTRACT
BACKGROUND: Although metastatic hormone-sensitive prostate cancer (mHSPC) treatments have evolved, androgen deprivation therapy (ADT) remains a widely used regimen. Therefore, this study sought patients who did not progress to castration-resistant prostate cancer (CRPC) but received ADT monotherapy and factors affecting overall survival (OS) in de novo mHSPC. METHODS: De novo mHSPC patients who received ADT treatment were included. ADT included luteinizing hormone-releasing hormone agonists with or without anti-androgen. The total cohort was divided into two groups relative to CRPC progression within two years. Logistic analysis was used to identify factors that did not progress CRPC within two years. Cox regression was used to assess the independent predictors for OS. RESULTS: The total cohort was divided into the no-CRPC within two years group (n = 135) and the CRPC within two years group (n = 126). Through multivariate logistic analysis, the life expectancy (odds ratio [OR] 0.95, 95% CI 0.91-0.99, p = 0.014) and Gleason scores (≥9 vs. ≤8; OR 0.43, 95% CI 0.24-0.75, p = 0.003) were associated with the group without castration-resistant prostate cancer progression within two years. The multivariate Cox model revealed that life expectancy (hazard ratio [HR] 0.951, 95% CI 0.904-0.999, p = 0.0491), BMI (HR 0.870, 95% CI 0.783-0.967, p = 0.0101), and CCI (≥2 vs. <2; HR 2.018, 95% CI 1.103-3.693, p = 0.0227) were significant predictive factors for OS. CONCLUSIONS: Patients with long life expectancy and a Gleason score of 9 or more were more likely to develop mCRPC while alive. Patients with short life expectancy, low BMI, and worsening comorbidity were more likely to die before progressing to CRPC. Although intensified treatment is essential for oncologic outcomes in mHSPC, shared decision making is integral for patients who may not benefit from this treatment.
ABSTRACT
INTRODUCTION: In cases of a noninfected malfunctioning inflatable penile prosthesis (IPP) device, surgeons often opt to exchange all of the device rather than the defective component for fear of an increased infection rate and future mechanical dysfunction. OBJECTIVES: To assess whether partial-component exchange of an IPP device has comparable outcomes to complete explant and replacement of an IPP device with or without a retained reservoir. METHODS: A systematic review was conducted following the PRISMA 2020 and AMSTAR guidelines. Searches were performed on MEDLINE (Ovid), PubMed, and the Cochrane Library from inception to June 2023, identifying studies reporting outcomes and complications of revision surgery for noninfected malfunctioning IPP devices. Three groups were compared: those undergoing single- or 2-component exchange, those with complete explantation and replacement, and those with replacement of all components while retaining the primary reservoir. RESULTS: Analysis included 11 articles comprising 12 202 patients with complete device replacement, 234 with partial device exchange, and 151 with retained reservoirs following revision. Mean ages ranged from 62 to 68 years, with median follow-up times between 3 and 84 months. Partial-component exchange showed a higher infection rate (6.3%) as compared with complete replacement (2.7%) and reservoir retention (3.9%). Similarly, partial exchange had a higher complication rate (23.9%) when compared with complete replacement (11.3%) and reservoir retention (19.6%). Mechanical failure rates for partial exchange were similar across the 3 groups (10%, 2.8%, and 5.8%, respectively). CONCLUSION: Partial-component exchange during IPP revision is associated with higher infection and perioperative complication rates but comparable rates of mechanical failure as compared with complete-component replacement, with or without retaining the original reservoir.

BACKGROUND: The duplex kidney is one of the common congenital anomalies of the kidney and urinary tract. We present two cases of renal tumor accompanied with ipsilateral duplex kidney. The image of the tumor, renal artery system and collecting system were rendered by AI software (Fujifilm's Synapse® AI Platform) to support the diagnosis and surgical planning. CASE PRESENTATION: Two Vietnamese patients (a 45-year-old man and a 54-year-old woman) with incidental cT1 renal cell carcinoma (RCC) were confirmed to have ipsilateral duplex kidneys by 3D reconstruction AI technique. One patient had a Renal score 9ah tumor of left kidney while the other had a Renal score 9 × tumor of right kidney in which a preoperative CT scan failed to identify a diagnosis of duplex kidney. Using the Da Vinci platform, we successfully performed robotic partial nephrectomy without any damage to the collecting system in both cases. CONCLUSION: RCC with duplex kidneys is a rare condition. By utilizing a novel AI reconstruction technique with adequate information, two patients with RCC in duplex kidneys were successfully performed robotic partial nephrectomy without complication.

Hyperspectral imaging has gained popularity for analysing remotely sensed images in various fields such as agriculture and medical. However, existing models face challenges in dealing with the complex relationships and characteristics of spectral-spatial data due to the multi-band nature and data redundancy of hyperspectral data. To address this limitation, we propose a novel approach called DiffSpectralNet, which combines diffusion and transformer techniques. The diffusion method is able extract diverse and meaningful spectral-spatial features, leading to improvement in HSI classification. Our approach involves training an unsupervised learning framework based on the diffusion model to extract high-level and low-level spectral-spatial features, followed by the extraction of intermediate hierarchical features from different timestamps for classification using a pre-trained denoising U-Net. Finally, we employ a supervised transformer-based classifier to perform the HSI classification. We conduct comprehensive experiments on three publicly available datasets to validate our approach. The results demonstrate that our framework significantly outperforms existing approaches, achieving state-of-the-art performance. The stability and reliability of our approach are demonstrated across various classes in all datasets.
ABSTRACT
Various guidelines recommend the first follow-up cystoscopy at 3 months; however, no data exist on the optimal timing for initial follow-up cystoscopy. We tried to provide evidence on the timing of the first cystoscopy after the initial transurethral resection of bladder tumor (TUR-BT) for patients with non-muscle invasive bladder cancer (NMIBC) using big data. This was a retrospective National Health Insurance Service database analysis. The following outcomes were considered: recurrence, progression, cancer-specific mortality, and all-cause mortality. Exposure was the time-to-treatment initiation (TTI), a continuous variable representing the time to the first cystoscopy from the first TUR-BT within 1 year. Additionally, we categorized TTI (TTIc) into five levels: < 2, 2-4, 4-6, 6-8, and 8-12 months. A landmark time of 1 year after the initial TUR-BT was described to address immortal-time bias. We identified the optimal time for the first cystoscopy using Cox regression models with and without restricted cubic splines (RCS) for TTI and TTIc, respectively. Among 26,660 patients, 16,880 (63.3%) underwent cystoscopy within 2-4 months. A U-shaped trend of the lowest risks at TTI was observed in the 2-4 months group for progression, cancer-specific mortality, and all-cause mortality. TTI within 0-2 months had a higher risk of progression (aHR 1.36; 95% confidence intervals [CI] 1.15-1.60; p < 0.001) and cancer-specific mortality (aHR 1.29; 95% CI 1.05-1.58; p = 0.010). Similarly, TTI within 8-12 months had a higher risk of progression (aHR 2.09; 95% CI 1.67-2.63; p < 0.001) and cancer-specific mortality (aHR 1.96; 95% CI 1.48-2.60; p < 0.001). Based on the RCS models, the risks of progression, cancer-specific mortality, and all-cause mortality were lowest at TTI of 4 months. The timing of the first cystoscopy follow-up was associated with oncologic prognosis. In our model, undergoing cystoscopy at 4 months has shown the best outcomes in clinical course. Therefore, patients who do not receive cystoscopy at approximately 4 months for any reason need more careful follow-up to predict a poor clinical course.

Introduction: Several studies have compared the safety and effectiveness of general and regional anaesthesia in percutaneous nephrolithotomy (PCNL). This study aimed to compare the perioperative and postoperative outcomes of general anaesthesia and regional anaesthesia for patients undergoing PCNL. Material and methods: For relevant articles, three electronic databases, including PubMed, Scopus, and Web of Science, were searched from their inception until March 2023. A meta-analysis has been reported in line with PRISMA 2020 and AMSTAR Guidelines. The risk ratio (RR) and mean difference (MD) were applied for the comparison of dichotomous and continuous variables with 95% confidence intervals (CI). Results: The final cohort analysis, comprised 3871 cases of PCNL, (2154 regional anaesthesia and 1717 general anaesthesia). Compared to general anaesthesia, the regional anaesthesia group had a significantly shorter length of stay (MD = -0.34 days, 95% CI -0.56 to -0.12, p = 0.002), lower postoperative nausea and vomiting rates (RR = 0.16, 95% CI 0.03 to 0.80, p = 0.026), lower complications grade III-V rates (RR = 0.68, 95% CI 0.53 to 0.88, p = 0.004), and lower postoperative visual analogue pain score (VAS) at 1 hour (MD = -3.5, 95% CI -4.1 to -2.9, p <0.001). There were no significant differences in other outcomes between the two groups. Conclusions: Our results show that PCNL under regional anaesthesia is safe and feasible, with comparable results to those done under general anaesthesia. While patient selection is important, counselling and decision-making for these procedures must go hand in hand to achieve the best clinical outcome.
ABSTRACT
The Western Pacific region is a diverse region experiencing fast economic growth and nutrition transition. We systematically examined 94 cohort studies on the associations of dietary and other lifestyle factors on non-communicable diseases (NCDs) in the region. These studies were mainly from China, Japan, the Republic of Korea, and Singapore. Patterns and changes in lifestyle risk factors for NCDs based on national surveys were examined. They showed some dietary intake improvements over the past three decades, featured as increased consumption of unsaturated oils, fruits, and vegetables, and decreased consumption of sodium and unhealthy fat. Despite a decrease in smoking rate and salt intake, the values remained higher than the global levels in 2019. The ultra-processed food intake in the region increased at a higher rate than the global estimate. National guidelines relevant to NCDs in five selected countries were highlighted. Strong future actions and policies are needed to tackle NCDs.
ABSTRACT
Acquired cystic disease-associated renal cell carcinoma (ACD-RCC) is a common subtype of renal cell carcinoma (RCC) in end-stage renal disease (ESRD) patients. The current systematic review and meta-analysis was performed to evaluate the clinicopathological, and genetic characteristics of patients with ACD-RCC. A systematic search on three electronic databases including the Pubmed, Scopus, and Web of Science databases were performed until December 31, 2022. A meta-analysis was performed following the PRISMA 2020 Guidelines. Of 888 identified articles, full-text screening in 69 articles, there were 26 articles analyzed, with a total of 2314 tumors in 2199 patients, including 418 ACD-RCC tumors in 363 patients, 1340 clear cell RCC (ccRCC) tumors, 308 papillary RCC (pRCC) tumors. Most ACD-RCC patients were male (80.2%). All the ACD-RCC patients underwent prior dialysis with 148.2 months of mean dialysis duration. There were 8.7%, 3.4%, and 5.8% tumors at the T3-4 stage, N1 stage, and M1 stage, respectively. The mean overall survival of ACD-RCC patients was 39.6 months (95% CI, 26.6-52.5). Compared to ccRCC and pRCC, ACD-RCC patients had a longer duration of dialysis (MD: 103.5 and 31.77 months, respectively; 95% CI: [75.48; 131.53] and [0.95; 62.58], respectively), and a higher rate of multifocal tumors (MD: 3.46 and 2.45 tumors, respectively; 95% CI [1.71; 6.98] and [1.26; 4.79], respectively). Regarding genetic characteristics, chromosomes 3 and 16 were the 2 most frequent chromosomal aberrations. The missense mutation in KMT2C (25%) and TSC2 (18.75%) were the 2 most common gene mutations in ACD-RCC. In conclusion, the ACD-RCC subtype exhibited several distinct clinicopathological and genetic characteristics compared to others RCC subtypes. Further researchs are needed to assess the survival outcome and the genetic characteristics of this subtype.

Introduction: Surgical training programs are pivotal in shaping skilled and compassionate surgeons, with mentors playing a crucial role in instilling clinical competence and essential attributes. This study aims to describe the characteristics of the program directors of Endourological Society-accredited fellowship programs. Methodology: The Endourological Society's website was used to identify program directors. The following data points were extracted: year of graduation from medical school, year of completing residency, if they had attended fellowship training or held additional degrees such as (PhD, MS, MBA, MSc, etc.), and number of publications on Scopus. Descriptive statistics were used to analyze the data. Results: A total of 84 fellowship programs and 115 program directors were identified. Geographically, 77.4% (n = 65) were in North America, 8.3% (n = 7) in Asia, 8.3% (n = 7) in the Middle East, 3.6% (n = 3) in Europe, and 2.4% (n = 2) in South America. Of the 115 program directors, 94.8% were male, and only 5.2% were female. Program directors graduated medical school with a median year of 1998 (1966-2015). Eighty percent attended fellowship programs, and 19.1% held additional degrees (PhD, MS, MBA, MSc, etc.). The median number of publications was 79 (4-1963), with a median citation of 1607 (1-43,565). The median H-index was 23 (range: 1-110). Conclusion: Most program directors of Endourological Society-accredited fellowship programs are fellowship-trained and a notable number held a second degree. However, a pronounced gender disparity is observed, with limited female representation among program directors. This assessment contributes valuable insights into the urology and endourology mentorship, emphasizing the need for broader diversity and inclusivity in leadership roles.

Background: Several centers have reported their experience with single-port robot-assisted partial nephrectomy (SP-RAPN); however, it is uncertain if utilization of this platform represents an improvement in outcomes compared to multiport robot-assisted partial nephrectomy (MP-RAPN). To evaluate this, we performed a meta-analysis to compare the perioperative, oncological, and functional outcomes between SP-RAPN and MP-RAPN. Methods: For relevant articles, three electronic databases, including PubMed, Scopus, and Web of Science, were searched from their inception until January 1, 2023. A meta-analysis has been reported in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 and assessing the methodological quality of systematic reviews (AMSTAR) guidelines. The odds ratio (OR) and weighted mean difference (MD) were applied for the comparison of dichotomous and continuous variables with 95% confidence intervals (CI). Results: Of the 374 retrieved abstracts, 29 underwent full-text review, and 8 studies were included in the final analysis, comprising a total cohort of 1007 cases of RAPN (453 SP-RAPN cases and 554 MP-RAPN cases). Compared to MP-RAPN, the SP-RAPN group had a significantly longer ischemia time (MD = 4.6 minutes, 95% CI 2.8 to 6.3, p < 0.001), less estimated blood loss (MD = -12.4 mL, 95% CI -24.6 to -0.3, p = 0.045), higher blood transfusion rate (OR = 2.97, 95% CI 1.33 to 6.65, p = 0.008), and higher postoperative estimated glomerular filtration rate (eGFR) at 6 months (MD = 4.9 mL/min, 95% CI 0.2 to 9.7, p = 0.04). There was no significant difference in other outcomes between the two approaches, including the intraoperative complication, overall postoperative complication, minor postoperative complication (Clavien-Dindo I - II), major postoperative complication (Clavien-Dindo III-V), conversion to radical nephrectomy, pain score on day #1, pain score on discharge, morphine milligram equivalent usage, hospital stay, positive surgical margins, and postoperative eGFR. Conclusions: SP-RAPN represents an emerging technique using a novel platform. Initial studies have demonstrated that SP-RAPN is a safe and feasible approach to performing partial nephrectomy, although with inferior outcomes for ischemia time and blood transfusion rates. Further studies will be necessary to define the best usage of SP-RAPN within the surgeon's armamentarium.

Introduction: After the introduction of same-day discharge (SDD) pathways for various surgeries, these pathways have demonstrated comparable complication rates and a reduced overall cost of care. Outpatient robot-assisted radical prostatectomy (RARP) is introduced in high-volume centers; however, patients' perspectives on the SDD RARP protocol are not well understood. Materials and Methods: A questionnaire consisting of 24 questions, including the Likert Decisional Regret Scale, was distributed to patients who underwent RARP at our center. The overall decision regret score was calculated as described in the literature. We used 15 as a cutoff point for differentiating between high- and low-regret rates. Median and interquartile range were determined for non-normally distributed variables, while mean ± standard deviation was calculated for continuous data. Results: Of the 72 patients who completed the questionnaire, 65.7% (n = 44) of patients felt no regret about their decision of choosing the SDD RARP protocol and 90.3% (n = 65) of men stated that they would have made the same decision. At the same time, 97.1% (n = 68) of patients would also recommend this procedure to others. The median decisional regret score of the cohort (n = 67) was 0 (0-10). Fifty-four of 67 (80.6%) patients were in the low-regret score group, while 13 (19.4%) were in the high-regret group. Patients in the high-regret group were more likely to have low household income (<$30,000 a year) and they experienced postoperative pain more frequently compared with patients in the lower regret group (7.7% vs 1.9%, p = 0.626, and 61.5% vs 38.9%, p = 0.212, respectively). Conclusions: Most patients expressed low regret about choosing the SDD pathway for RARP, underscoring the importance of thorough explanation of the procedure and discharge process to enhance patient experience. However, a subset of patients did express regret, possibly due to an interplay of patient- and procedure-related factors.

INTRODUCTION: In this case report, we demonstrate our technique of a retroperitoneal laparoscopic heminephrectomy for a T1b right hilar tumor in a horseshoe kidney. CASE PRESENTATION: A 77-year-old Vietnamese woman presented to the hospital because of right flank pain. On presentation, her serum creatinine was 0.86 mg/dL and glomerular filtration rate was 65.2 mL/minute/1.73 m2. According to her renal scintigraphy, glomerular filtration rates of the right and left moieties were 24.2 and 35.5 mL/minute, respectively. Computed tomography imaging demonstrated a 5.5 × 5.0 cm solid hilar mass with a cT1bN0M0 tumor stage was in the right moiety. After discussion, the patient elected a minimally invasive surgery to treat her malignancy. The patient was placed in a flank position. We used Gaur's balloon technique to create the retroperitoneal working space, and four trocar ports were planned for operation. Three arteries were dissected, including two arteries feeding the right moiety, one artery feeding the isthmus, and one vein, which was clipped and divided by Hem-o-lok. The isthmusectomy was performed with an Endostapler. Consequently, the ureter was clipped and divided. Finally, the whole right segment of the horseshoe kidney was mobilized and taken out via the flank incision. RESULTS: The total operative time was 250 min with an estimated blood loss of 200 mL. The patient's serum creatinine after surgery was 1.08 mg/dL, and glomerular filtration rate was 49.47 mL/minute/1.73 m2. The patient was discharged on postoperative day #4 without complication. Final pathologic examination of the tumor specimen revealed a Fuhrman grade II clear cell renal cell carcinoma, capsular invasion, with negative surgical margins. After a three-month follow-up, the serum creatinine was 0.95 mg/dL, and glomerular filtration rate was 57.7 mL/minute/1.73 m2. Local recurrence or metastasis was not detected by follow-up computed tomography imaging. CONCLUSIONS: Retroperitoneal laparoscopic heminephrectomy is a safe and feasible technique for patients with renal cell carcinoma in a horseshoe kidney and may be particularly useful in low income settings without access to robotic technology.

Objectives: This study examines the status of implementation of the International Code of Marketing of Breast-milk Substitutes of eight countries in the South Asia region (Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka), and describes the sales value and volume of commercial milk formula (CMF) marketed as breastmilk substitutes (BMS) and baby food in four countries (Bangladesh, India, Pakistan, and Sri Lanka). Design: A mix of descriptive methods is used to assess national status of Code implementation, including a desk review of the 2022 WHO/UNICEF/IBFAN Code Status Report, systematic content analysis of national Code measures, and insights generated from the participation of key government and UNICEF/WHO actors in a regional workshop that aimed to identify each country's barriers, gaps, and the status of Code implementation. Data on the sales value and volume of CMF and baby food between 2007 to 2021 and with the prediction to 2026 in Bangladesh, India, Pakistan, and Sri Lanka were obtained from Global Data. Findings: There are major gaps in Code implementation in countries even with legal measures considered substantially aligned with the Code, such as the inadequate age range of CMF covered in the scope, insufficient safeguards against conflicts of interest in the health system, lack of warning of risks of intrinsic contamination of powdered milk formula, and an absence of effective monitoring and enforcement mechanisms. Data on CMF sales shows health facilities and pharmacies sustain the highest sales. Lower sales volume of infant formula (including special formula), compared to other CMF such as follow-up formula and growing-up milk, has been observed in three of the four countries (Bangladesh, India, and Sri Lanka). Overall, GUM, followed by baby cereals, accounted for a large portion of CMF and baby foods sales in the same three countries. Recommended actions include: (1) Closing the gaps between national measures and the Code, (2) Ensuring effective monitoring and enforcement mechanisms, (3) Strengthening conflicts of interest safeguards in the health system, (4) Tackling digital marketing, and (5) Galvanizing political support and support from in-country public health and women's rights jurist networks.

There is a growing recognition globally that care regarding lactation following a perinatal death needs to potentially offer the opportunity for maternal donation. This article discusses this experience and perspectives from a human milk bank (HMB) in Vietnam. This is a descriptive exploratory case study that has a long tradition in both the social and health sciences. Triangulated data collection involved a review of video data, interview data with the donor, and data review for the Da Nang HMB, a Center for Excellence in Breastfeeding. We found that although it is common for mothers in Vietnam to donate breastmilk to HMBs, it is less common for this to occur following perinatal loss. We offer a descriptive case study of the maternal loss of twins and a subsequent choice to donate for approximately 1 month to the Da Nang HMB, the first HMB in Vietnam. We discuss four reasons derived from this case regarding donation following perinatal loss. (1) A strong motivation to donate breastmilk when aware of the service, (2) donating breastmilk helped her deal with grief, (3) family members supported her through this tough time and supported her decision, and (4) health staff supported her decision. While human milk sharing (e.g., wet nursing) has been practiced in Vietnam, breastmilk donation from bereaved mothers has neither been discussed nor well-researched. Because maternal grief is complex and individual, deciding to donate breastmilk is a personal decision that needs to be supported, without creating guilt for those who do not wish to donate.
ABSTRACT
Purpose: Artificial Intelligence (AI) imitating human-like language, such as ChatGPT, has impacted lives throughout various multidisciplinary fields. However, despite these innovations, it is unclear how well its implementation will assist patients in clinical situations. We evaluated changes in patient perceptions regarding AI before and after reading a ChatGPT-written explanation. Materials and methods: In total, 24 South Korean patients receiving urolithiasis treatment were surveyed through questionnaires. The ChatGPT explanatory note was provided between the first and second questionnaires, detailing lifestyle modifications for preventing urolithiasis recurrence. The study questionnaire was the Korean version of the General Attitudes toward Artificial Intelligence Scale, including positive and negative attitude items. Wilcoxon signed-rank tests were accomplished to compare questionnaire scores before and after receiving the explanatory note. A linear regression analysis with stepwise elimination was used to assess variable (demographic data) accuracy in predicting outcomes. Results: There were significant differences between total negative questionnaire scores pre- and post-surveys of ChatGPT, but not in the positive scores. Among variables, only education level significantly influenced mean score differences in the negative questionnaires. Conclusions: The negative perception change among urolithiasis patients after receiving the explanatory note provided by the AI chatbot program was observed, evidencing that patients with lower education levels expressed a more negative response. The explanatory note provided by the AI chatbot program could provoke an adverse change in AI perception. Negative human responses must be considered to improve and adapt new technology in health care. Only through changing patient perspectives will upgraded AI technology integrate into medical healthcare.
ABSTRACT
Background: Donor human milk (DHM) is essential to the operation of human milk banks (HMB). This study examined characteristics and factors associated with higher volumes of DHM donation at the first HMB in Vietnam. Method: Data from an online HMB monitoring system collected between February 2017 and July 2022 included demographic characteristics, child information, the timing of donation, and the volume of DHM. Higher volume is defined as equal to or greater than the median DHM volume per donor of 14.4â liters (L). Potential contributors to higher DHM volume were examined using the chi-square test in univariate and multivariable logistic regression analysis. Results: During the 5.5-year operation, this HMB recruited 517 donors with an average age of 28.6 years. Approximately 60.9% of donors had a college or higher degree and 97.3% gave birth in Da Nang city. Of these donors, the prevalence of cesarean birth was 48.2%, preterm births was 40.2%, and 27.9% had babies with a birth weight of less than 1,500â g. There was a similar proportion of donors between the hospital (48.2%) and community (51.8%). On average, hospital donors started their donations 15 days after birth when their newborns were 33.9 weeks corrected age compared to 63 days and 47.7 weeks among community-based donors. The overall median volume of DHM per donor was 14.4â L over a period of 46 days. The amount and duration were higher in community-based donors (17.5â L in 72 days, 300â ml/day) than those in the hospital (8.4â L in 30 days, 258â ml/day). More than 37% of donors contacted the HMB themselves; the remainder were introduced by health professionals. Factors associated with higher volumes of DHM included higher education (OR: 1.77; 95% CI: 1.09, 2.87), having a full-term newborn (OR: 2.46; 95% CI: 1.46, 4.13), and community-based donors (OR: 2.15; 95% CI: 1.22, 3.78). Conclusions: Mothers with higher education and from the community donate more breastmilk over a longer duration than those with lower education and from the hospital. Breastfeeding protection, promotion, and support should be offered to all mothers with specialized breastfeeding support for mothers of preterm and sick infants. This will ensure mothers have sufficient breastmilk for their newborns and potentially surplus breastmilk for donation.

Background: Multiple oral chemotherapeutic agents for metastatic hormone-sensitive prostate cancer (mHSPC) have been developed for conjugated use with conventional androgen deprivation therapy (ADT). Several randomized controlled trials (RCTs) report significant benefits in mHSPC patients. Therefore, we compared overall survival (OS) and progression-free survival (PFS) benefits among considerable mHSPC oral chemotherapeutic agents. Materials and methods: We investigated mHSPC treatment efficacy through a systematic RCT-trial literature review (PubMed, Embase, Web of Science, the Cochrane Library, and Scopus). Two reviewers independently screened, extracted data, and assessed bias risk in duplicate. Results: We identified 18 RCTs (n = 13,509). Concerning OS, ADT + abiraterone, ADT + abiraterone + docetaxel, ADT + apalutamide, ADT + bicalutamide, ADT + darolutamide + docetaxel, ADT + enzalutamide, ADT + orteronel, and ADT + rezvilutamide were more effective than the standard of care (SOC). Comparing PFS, most treatments were more effective than SOC, excluding ADT + bicalutamide, nilutamide, flutamide, ADT + bicalutamide + palbociclib, and ADT + nilutamide. ADT + docetaxel with androgen receptor targeted agent (ARTA) triplet therapy was not among the top three treatments determined through ranking analysis. Conclusions: Novel oral chemotherapeutic agent combination therapies must replace current ADT monotherapy and ADT + docetaxel SOC. Even so, ADT + docetaxel with ARTA triplet therapy still is not the best mHSPC treatment and requires further study.
ABSTRACT
Background: Postoperative urinary incontinence after robot-assisted radical prostatectomy (RARP) represents a bothersome side effect, which may permanently affect patient's quality of life. Several studies have demonstrated that obstructive sleep apnea syndrome (OSAS) is associated with urinary symptoms such as urge incontinence, overactive bladder, and nocturia. In this study, we sought to further explore the effect of OSAS on urinary continence after RARP. Methods: We queried our prospectively collected institutional RARP database and identified 82 patients with OSAS and 131 controls, which were matched for age and body mass index (BMI), with available follow-up data for continence. To minimize selection bias, we conducted a propensity score-matched analysis. Patient's characteristics and urinary continence outcomes were compared between the two groups before and after propensity-score matching. Kaplan-Meier curves were constructed to assess the difference in continence between the two groups. Results are presented as means with standard deviations and percentages with 95% confidence intervals (CIs). Results: A total of 213 patients were included in the analysis, of whom 82 with OSAS and 131 with non-OSAS (control group). The mean age of the total cohort was 61.7 ± 6.96 years, the mean BMI was 30.4 ± 5.36, and 52% of the cohort were classified as obese (BMI ≥30). In post-propensity score-matched analyses, there was no significant difference in baseline demographics and tumor characteristics between the two groups (included 82 cases in each group). The median time to continence was 6.6 months for the control group as compared with 13.0 months for the OSAS group (p < 0.001). At 12 months the continence rate for the OSAS group was 41.2% (95% CI: 28.9%-51.4%) as compared with 61.7% (95% CI: 28.5%-71.5%) for the control group. At 24 months the continence rate for the OSAS group was 68.7% (95% CI: 56%-77.7%) as compared with 90.8% (95% CI: 79%-96%) for the control group. Conclusion: On matched analysis, we found that patients with OSAS tended to demonstrate worse urinary continence recovery as compared with patients without OSAS. Additional investigation will be necessary to confirm these initial findings.

BACKGROUND: We aimed to assess the trends in urinary tract infections (UTIs) and prognosis of patients with prostate cancer after radical prostatectomy (RP) and radiation therapy (RT) as definitive treatment options. METHODS: The data of patients diagnosed with prostate cancer between 2007 and 2016 were collected from the National Health Insurance Service database. The incidence of UTIs was evaluated in patients treated with RT, open/laparoscopic RP, and robot-assisted RP. The proportional hazard assumption test was performed using the scaled Schoenfeld residuals based on a multivariable Cox proportional hazard model. Kaplan-Meier analysis were performed to assess survival. RESULTS: A total of 28,887 patients were treated with definitive treatment. In the acute phase (< 3 months), UTIs were more frequent in RP than in RT; in the chronic phase (> 12 months), UTIs were more frequent in RT than in RP. In the early follow-up period, the risk of UTIs was higher in the open/laparoscopic RP group (aHR, 1.63; 95% CI, 1.44-1.83; p < 0.001) and the robot-assisted RP group (aHR, 1.26; 95% CI, 1.11-1.43; p < 0.001), compared to the RT group. The robot-assisted RP group had a lower risk of UTIs than the open/laparoscopic RP group in the early (aHR, 0.77; 95% CI, 0.77-0.78; p < 0.001) and late (aHR, 0.90; 95% CI, 0.89-0.91; p < 0.001) follow-up periods. In patients with UTI, Charlson Comorbidity Index score, primary treatment, age at UTI diagnosis, type of UTI, hospitalization, and sepsis from UTI were risk factors for overall survival. CONCLUSIONS: In patients treated with RP or RT, the incidence of UTIs was higher than that in the general population. RP posed a higher risk of UTIs than RT did in early follow-up period. Robot-assisted RP had a lower risk of UTIs than open/laparoscopic RP group in total period. UTI characteristics might be related to poor prognosis.
