Efficacy of differential reinforcement of other behaviors therapy for tic disorder: a meta-analysis.

INTRODUCTION: Recently, studies on behavioral tic suppression techniques have gained popularity as opposed to pharmacological alternatives that often have potentially dangerous side effects. Differential Reinforcement of Other Behaviors therapy (DRO) is one such behavioral technique whose efficacy in tic suppression has been experimentally demonstrated albeit in studies with very few patients, and lacking statistical power. Here, we conducted a meta-analysis of these studies to improve their overall power and explore whether DRO intervention is really effective for tic suppression. MATERIALS AND METHODS: PubMed, Embase, PsycINFO, and Cochrane Library were searched from inception to August 30, 2023. Only original interventional studies that examined the efficacy of DRO for tic suppression were included. RESULTS: A total of 8 no control interventional studies involving 79 children with tic disorders were recruited. Most of the children had moderate tic severity. The pooled mean Yale Global Tic Severity Scale (YGTSS) score was 24.64 (95% CI: 21.99 - 30.12, p = < 0.00001, I2 = 87%). In terms of efficacy of the DRO technique for tic suppression, the results showed that DRO was effective in reducing tic frequency among the children. The pooled standardized mean difference (SMD) was -10.25 (95% CI: -14.71 - -5.79, p = < 0.00001) with I2 = 94%. CONCLUSION: In conclusion, this study revealed that DRO is potentially an effective tic suppression technique for temporarily managing tic disorder. It also showed that DRO could be employed for both moderate and severe tic disorders. However, the technique bears crucial limitations that limit its implementation outside of experimental settings. More studies are needed to address these limitations and improve its applicability in the real world.

Altered intra- and inter-network brain functional connectivity associated with prolonged screen time in pre-school children with autism spectrum disorder.

Prolonged screen time (ST) has adverse effects on autistic characteristics and language development. However, the mechanisms underlying the effects of prolonged ST on the neurodevelopment of children with autism spectrum disorder (ASD) remain unclear. Neuroimaging technology may help to further explain the role of prolonged ST in individuals with ASD. This study included 164 cases, all cases were divided into low-dose ST exposure (LDE group 108 cases) and high-dose ST exposure (HDE group 56 cases) based on the average ST of all subjects. Spatial independent component analysis (ICA) was used to identify resting state networks (RSNs) and investigate intra- and inter-network alterations in ASD children with prolonged ST. We found that the total Childhood Autism Rating Scale (CARS) scores in the HDE group were significantly higher than those in the LDE group (36.2 ± 3.1 vs. 34.6 ± 3.9, p = 0.008). In addition, the developmental quotient (DQ) of hearing and language in the HDE group were significantly lower than those in the LDE group (31.5 ± 13.1 vs. 42.5 ± 18.5, p < 0.001). A total of 13 independent components (ICs) were identified. Between-group comparison revealed that the HDE group exhibited decreased functional connectivity (FC) in the left precuneus (PCUN) of the default mode network (DMN), the right middle temporal gyrus (MTG) of the executive control network (ECN), and the right median cingulate and paracingulate gyri (MCG) of the attention network (ATN), compared with the LDE group. Additionally, there was an increase in FC in the right orbital part of the middle frontal gyrus (ORBmid) of the salience network (SAN), compared with the LDE group. The inter-network analysis revealed increased FC between the visual network (VN) and basal ganglia (BG) and decreased FC between the sensorimotor network (SMN) and DMN, SMN and ATN, SMN and auditory network (AUN), and DMN and SAN in the HDE group, compared with the LDE group. There was a significant negative correlation between altered FC values in MTG and total CARS scores in subjects (r = - 0.18, p = 0.018).  Conclusion: ASD children with prolonged ST often exhibit lower DQ of language development and more severe autistic characteristics. The alteration of intra- and inter-network FC may be a key neuroimaging feature of the effect of prolonged ST on neurodevelopment in ASD children.  Clinical trial registration: ChiCTR2100051141. What is Known: • Prolonged ST has adverse effects on autistic characteristics and language development. • Neuroimaging technology may help to further explain the role of prolonged ST in ASD. What is New: • This is the first study to explore the impact of ST on intra- and inter-network FC in children with ASD. • ASD children with prolonged ST have atypical changes in intra- and inter-brain network FC.

Comparison of the efficacy of parent-mediated NDBIs on developmental skills in children with ASD and fidelity in parents: a systematic review and network meta-analysis.

BACKGROUND: Recently, studies on behavioral interventions for autism have gained popularity. Naturalistic Developmental Behavior Interventions (NDBIs) are among the most effective, evidence-based, and widely used behavior interventions for autism. However, no research has been conducted on which of the several NDBI methods is most effective for parents and children with autism spectrum disorders. Therefore, we conducted a network meta-analysis to compare the specific effects of each type of parental-mediated NDBI on children's developmental skills and parent fidelity. METHODS: PubMed, Embase, Cochrane Library, Medline, Web of Science, China National Knowledge Infrastructure (CNKI), CINAHL, and Wanfang databases were searched from inception to August 30, 2023. A total of 32 randomized controlled trial studies that examined the efficacy of different NDBIs were included. RESULTS: Parents of children with ASD who received Pivotal Response Treatment (PRT) reported significant improvements in their children's social skills (SUCRA, 74.1%), language skills (SUCRA, 88.3%), and parenting fidelity (SUCRA, 99.5%). Moreover, parents who received Early Start Denver Model (ESDM) reported significant improvements in their children's language (SMD = 0.41, 95% CI: 0.04, 0.79) and motor skills (SMD = 0.44, 95% CI: 0.09, 0.79). In terms of the efficacy of improving parent fidelity, the results showed that the Improving Parents as Communication Teachers (ImPACT) intervention significantly improved parent fidelity when compared with the treatment-as-usual group (TAU) (SMD = 0.90, 95% CI: 0.39, 1.42) and the parental education intervention (PEI) (SMD = 1.10, 95% CI:0.28, 1.91).There was a difference in parent fidelity among parents who received PRT(SMD = 3.53, 95% CI: 2.26, 4.79) or ESDM(SMD = 1.42, 95% CI: 0.76, 2.09) training compared with PEI. CONCLUSION: In conclusion, this study revealed that parents can achieve high fidelity with the ImPACT intervention, and it can serve as an early first step for children newly diagnosed with ASD. It also showed that parent-mediated ESDM is effective in improving language and motor skills for children with ASD and can be used as part of the second stage of parent training. Parent-mediated PRT can also be used as a third stage of parent training with sufficient training intensity to further improve language, social, and motor skills.

Emergency holmium laser enucleation of the prostate (HoLEP): a novel approach in the management of refractory hematuria for patients with benign prostatic hyperplasia (BPH): a single-institution experience.

INTRODUCTION: Refractory hematuria secondary to prostatic disease typically resolves with conservative management; however, this condition may require hospitalization with extensive measures to control life-threatening bleeding. The aim of this study was to report our experience using holmium laser enucleation of the prostate (HoLEP) as an emergency treatment in this clinical setting. METHODS: We conducted a retrospective review of all patients that presented to the emergency department with refractory hematuria of prostatic origin from October 2017 to September 2021, for whom hospitalization and conservative management failed to control bleeding. All emergency HoLEP procedures were performed by a single surgeon. Preoperative and intraoperative parameters, as well as perioperative outcomes, were collected and analyzed. Postoperative outcomes included duration of foley catheterization, length of postoperative hospital stay, and hospital readmissions. RESULTS: A total of 40 emergency HoLEP procedures were performed. Our cohort had a median prostate volume of 110.5 cc and a median resected weight of 81 g. Twenty-seven patients (67.5%) were on anticoagulant or antiplatelet medications on admission. The urethral catheter was removed within 1 day in 95% of patients with a successful trial of void (TOV). Moreover, 92.5% of patients were discharged home within 24 h of their procedure. Two patients (5%) experienced clot retention within one-week post-discharge with a 2.5% overall readmission rate. All postoperative parameters, including International Prostate Symptom Score (IPSS), quality of life (QoL), maximum flow rate (Qmax), and post-void residual volume (PVR), showed significant improvement at 1 year follow up. CONCLUSION: Our experience demonstrates that emergency HoLEP is an effective treatment option for patients with refractory hematuria of prostatic origin. Further studies are warranted to consolidate our results.

Adenylate kinase 2 is a biomarker related to the prognosis of glioma and the immune microenvironment.

BACKGROUND: Among the brain and the other central nervous system, gliomas are the most prevalent malignant primary tumors. Adenylate kinase 2 (AK2) is generally thought to be crucial for energy metabolism and signal transduction. Several disorders are correlated with its aberrant expression. However, it is unclear what functions AK2 might have in gliomas. METHODS: We investigated the relationship between AK2 expression and clinicopathological features of glioma patients using information obtained from public databases and patient tissue microarrays. AK2 knockdown glioma cell lines were constructed to explore how AK2 affects glioma progress. The association between AK2 and the immune microenvironment in gliomas was evaluated by multiple methods. RESULTS: AK2 expression was higher in glioma samples than in normal brain tissues. Older patients and those with higher-grade, IDH-wildtype, 1p/19q codeletion-free, and MGMT-unmethylated tumors had higher levels of AK2 expression, linking to poor outcomes. Thus, gliomas with high AK2 expression have a worse prognosis. GO and KEGG analyses demonstrated that AK2 was relevant to cell division and DNA replication. Downregulation of AK2 suppresses cell proliferation, migration, and colony formation of glioma cell lines in vitro. AK2 expression was positively connected to the inhibitory immune checkpoints, also correlating with immune infiltration degree. CONCLUSIONS: In this study, AK2 may be a potential biological target for more precise molecular therapy of gliomas, since its high expression is associated with worse outcomes and a more malignant immune microenvironment.

Age-stratified potency outcomes of bilateral nerve sparing robotic-assisted radical prostatectomy.

INTRODUCTION: This study aims to report age-stratified potency outcomes in men undergoing robot-assisted radical prostatectomy (RARP). MATERIALS AND METHODS: A retrospective review was performed on a database of 1737 patients who underwent RARP for localized prostate cancer between 2007 and 2019. Inclusion criteria consisted of patients undergoing bilateral nerve-sparing RARP. Exclusion criteria were preoperative Sexual Health Inventory for Men (SHIM) score < 17 and postoperative androgen deprivation therapy or radiotherapy. Patients were divided into four cohorts based on age: ≤ 54 years (group 1); 55-59 years (group 2); 60-64 years (group 3) and ≥ 65 years (group 4). Functional outcomes were measured up to 36 months. Kaplan-Meier analysis was performed to compare the time to recovery of potency stratified by age groups using log-rank testing. RESULTS: A total of 542 patients met the selection criteria. Potency rates were significantly different between groups. Groups 1 through 4 demonstrated potency recovery rates of 64.2%, 52.3%, 36.6% and 20.7% at 1-year follow up, respectively. After 3 years, groups 1 through 4 had potency rates of 77.9%, 67.0%, 50.5% and 35.0%, respectively. Recovery of potency was achieved at a median time after surgery of 199, 340 and 853 days for groups 1-3, respectively. The Cox proportional hazard model showed that older age, higher body mass index (BMI), and lower preoperative SHIM score were associated with significantly higher rates of impotence. CONCLUSION: This study shows that RARP has acceptable potency outcomes, regardless of age. However, patient factors, including older age and preoperative SHIM were significantly associated with poorer functional recovery. This data is valuable in prognostic evaluation and patient counseling.

Intramedullary Kirschner wire fixation of displaced distal forearm fractures in children.

AIM OF THE WORK: This study was designed to highlight internal fixation by intramedullary K-wires for displaced distal forearm fractures among children and analyze the results of this technique. We hypothesize that physis-sparing intramedullary fixation prevents displacement with a lower complication rate. METHODS: This prospective case series involving 47 patients was conducted between February 2018 and December 2019. All patients with open physis presented with recent displaced distal forearm fractures were included, and all of them were treated with an intramedullary k-wire fixation for both bones with the assessment of the union rate, union time, suspected complication, radiographic evaluation, and functional outcome. RESULTS: The study population consisted of 31 boys (66%) and 16 girls (34%). The mean age of the patients was 10.68 ± 2.728 years (range, 7-15 years). All fractures were united in a median of 6 weeks (range, 4-8 weeks), The functional outcome after 12 months was normal in 42 patients (89.4%), whereas, in five patients (10.6%), the functional parameters were minimally reduced. The median preoperative angulation improved from 36° (range, 24°-52°) preoperatively to 4° (range, 0°-10°) on immediate postoperative radiographs. After 12 months, the median angulation was 2° (range, 0°-7°) (p < 0.001). The angulation of the distal radius immediately after surgery and at the final follow-up was statistically correlated with the functional outcome (p < 0.001 and 0.002, respectively). CONCLUSION: This technique provides a good result with less susceptibility to re-displacement and low complication rates. LEVEL OF EVIDENCE: Level IV.

Global experience and progress in GreenLight-XPS 180-Watt photoselective vaporization of the prostate.

PURPOSE: To evaluate changes in global perioperative data of GreenLight-XPS 180-Watt photo-selective vaporization of the prostate (GL-XPS) of the Global Greenlight Group (GGG) database. METHODS: 3441 men, who underwent GL-XPS for symptomatic BPH between 2011 and 2019 at seven high volume international centers, were included. Primary outcome measurements were operative time (OT; min), effective laser time (LT; min of OT), as well as intraoperative and postoperative adverse events (AEs), all analyzed by year of surgery (2011-2019) and prostate volume (PV) group (< 80 ml vs. 80-150 ml vs. > 150 ml). RESULTS: The median age was 70 years (interquartile range 64-77), the median PV was 64 ml (IQR 47-90). The OT and LT slightly increased but stayed highly efficient all in all. Median OT was 60 min (IQR 45-83) and LT was 33 min (IQR 23-46). Median energy use was 253 kJ (IQR 170-375) with an energy density of 3.94 kJ/ml (IQR 2.94-5.02). The relative probability of perioperative AEs decreased by 17% each year (p < 0.001). The relative probability of perioperative transfusion dropped significantly from 2% in 2011 to 0% in 2019 (p = 0.007). The early postoperative complications (within 30 days after surgery) decreased significantly from 48.8% (n = 106) in 2011 to 24.7% (n = 20) in 2019 (p > 0.001). CONCLUSION: These findings from the GGG demonstrate significant improvement secondary to growing experience with GL-XPS between 2011 and 2019 in intraoperative AEs, including transfusions, and postoperative AEs. While staying highly efficient in OT and LT of GL-XPS within a 9-year period of experience.

Theoretical investigations of optical properties of FeF2.

Density functional theory has been employed to determine ground state properties and calculate the complex dielectric function of the FeF2 compound. The complex expression of magnetic permeability has been estimated using the formula of the magnetic permeability tensor. To interpret the optical transitions, densities of states and projected densities of states have been determined. Suitable expressions for treating contributions of electric permittivity and magnetic permeability to optical properties have been derived and applied. The absorption coefficient in the visible range is a result of the transitions from the top of the valence band to 4s bands of Fe2+ cations in the conduction band. In the far-infrared region, FeF2 is a perfect reflector. The estimated optical properties show good agreement with previous theoretical and experimental results in the literature.

Age-stratified continence outcomes of robotic-assisted radical prostatectomy.

INTRODUCTION: Incontinence after robot-assisted radical prostatectomy (RARP) significantly impacts quality of life. This study aims to compare the age-stratified continence outcomes in Canadian men undergoing RARP. MATERIALS AND METHODS: A retrospective review was performed on a prospectively maintained database of 1737 patients who underwent RARP for localized prostate cancer between 2007 and 2019. Patients were stratified into five groups based on age: group 1, ≤ 54 years (n = 245); group 2, 55-59 years (n = 302) ; group 3, 60-64 years (n = 386); group 4, 65-69 years (n = 348); and group 5, ≥ 70 years (n = 116). Functional outcomes were assessed up to 36 months. Log-rank and multivariable Cox regression analyses were performed to compare the time to recovery of pad-free continence by age group. RESULTS: Continence rates of groups 1 to 5 were respectively 90.2%, 79.1%, 80.4%, 71.4%, and 59.8% at 1-year follow up (p < 0.001). After 3 years, groups 1 through 5 had continence rates of 97%, 91.7%, 89.3%, 81.4%, and 77.6%, respectively (p < 0.001). Median time to recovery of continence was 58, 135, 140, 152 and 228 days, respectively. Among men who remained incontinent, older patients consistently required more pads. In Cox proportional hazard model, groups 2, 3, 4 and 5 were respectively 33% (p < 0.001), 34% (p < 0.001), 33% (p = 0.001), and 41% (p = 0.005) more likely to remain incontinent compared to group 1. CONCLUSIONS: Age is associated with significantly lower rates of continence recovery, longer time to recovery of continence, and more severe cases of incontinence after RARP.

Mercury contamination in the riparian ecosystem during the reservoir discharging regulated by a mega dam.

Mercury (Hg) is extremely poisonous and can be absorbed through touch, inhalation, or consumption. In the living environment, Hg in contaminated sediment can be transferred into grass by the direct absorption through the roots or shoots. The intake of Hg due to Hg emissions may pose a threat to living bodies especially to human beings. The present study aims to provide a novel insight about total mercury (THg) and methyl mercury (MeHg) in a riparian grass (Cynodon dactylon (L).Pers) and sediments during the discharging phase (summertime at 145 m water level) in Three Gorges Reservoir (TGR-China); where C. dactylon is a dominant perennial herb in the riparian zone. Yet, the potential risk of Hg contamination in the riparian ecosystem is not thoroughly assessed in the dam regulated reservoir. This study was conducted in the riparian zones of the reservoir formed by a mega dam (Three Gorge Dam) which regulates the water levels during the summer and winter period in the TGR. Our results showed that riparian sediments were acting as a sink for THg and MeHg. Insignificant correlation of THg and MeHg was found between the amphiphyte C. dactylon and its surrounding sediments in the TGR. Bioconcentration factors values for MeHg were found higher than 1 in all study locations in the riparian zones in TGR, which could be due to action of certain bacteria/purely chemical-based methylation on inorganic form of Hg. Additionally, translocation factor indices also highlighted that the amphiphyte C. dactylon was MeHg accumulator in riparian zones. These results suggested that since riparian sediment was found acting as the sink for THg and MeHg during discharging phase, MeHg contamination in the amphiphyte C. dactylon in riparian zones was not caused by the riparian sediments but by other factors, for instance, the anthropogenic activities in the TGR. Finally, this study leads to conclude that amphiphyte C. dactylon can be used as biomonitoring agent for Hg pollution in the TGR.

Oncological safety and functional outcomes of testosterone replacement therapy in symptomatic adult-onset hypogonadal prostate cancer patients following robot-assisted radical prostatectomy.

PURPOSE: Testosterone replacement therapy (TRT) remains controversial in men with treated prostate cancer. We assessed its safety and functional impacts in patients after definitive surgical treatment with robotic-assisted radical prostatectomy (RARP). METHODS: We performed a retrospective analysis of 1303 patients who underwent RARP during the years 2006-2019. We identified men with symptoms of andropause and low serum testosterone who received TRT post-RARP; then we divided the cohort into two groups accordingly for comparison. Biochemical recurrence (BCR) was the primary endpoint. Secondary endpoints included functional outcomes. Predictors of BCR, including the effect of TRT on BCR, were evaluated using univariable and multivariable logistic regression. RESULTS: Among the forty-seven men who received TRT, the mean age was 60.83 years with a median follow-up of 48 months. Three (6.4%) and 157 (12.56%) patients experienced BCR in TRT and non-TRT groups, respectively. Baseline characteristics were similar between both groups except for higher mean BMI in the TRT group (p = 0.03). In the multivariate analysis (MVA), higher pre-RARP prostate-specific antigen (PSA) (p = 0.043), higher International Society of Urological Pathology score (p < 0.001), seminal vesical invasion (p = 0.018) and positive surgical margin (p < 0.001) were predictors of BCR. However, TRT was not (p = 0.389). In addition, there was a significant change in the Sexual Health Inventory for Men (p = 0.022), and serum testosterone level (p < 0.001) before and 6 months after initiation of TRT. CONCLUSION: Our findings suggest that TRT, in well-selected, closely followed, symptomatic men post-RARP is an oncologically safe and functionally effective treatment in prostate cancer patients post-RARP.

Reasons to believe in vaporization: a review of the benefits of photo-selective and transurethral vaporization.

PURPOSE: In the current review, we will discuss the state of the literature of vaporization of the prostate for the treatment of benign prostatic enlargement (BPE). We discuss two methods of vaporization of the prostate: Transurethral Vaporization of the Prostate (TUVP) and Greenlight Photo-selective Vaporization of the Prostate (PVP). METHODS: A comprehensive review of the literature was performed on TUVP and PVP. The literature on transurethral resection of the prostate (TURP) was also extensively reviewed as a comparative surgical method. RESULTS: The evidence shows that TUVP appears to be the safer choice, as compared to TURP due to less intra- and peri-operative complications. PVP was associated with less bleeding complications than TURP with outpatient discharge. Importantly, PVP was not associated with serious bleeding events requiring blood transfusions or medical treatment in patients under anticoagulation or antiplatelet therapies. PVP was also shown to be a cost-effective option compared to TURP. CONCLUSION: Prostate vaporization for the treatment of BPE appears to be an efficient and safer alternative to TURP. Vaporization techniques, particularly Greenlight PVP, should be offered to most men, especially those under anticoagulation therapy, as well as patients at risk of bleeding complications.

Reasons to go for Rezum steam therapy: an effective and durable outpatient minimally invasive procedure.

PURPOSE: In this review, we will discuss the state of the literature regarding Rezum and opportunities for its application in the treatment of BPH. METHODS: A comprehensive review of original research on convective water vapor thermal therapy (Rezum) was conducted. Articles related to transurethral resection of the prostate, holmium laser enucleation of the prostate, Aquablation, and greenlight photoselective vaporization of the prostate were reviewed for discussion. RESULTS: Rezum distinguishes itself from other treatment options by its durable improvement in objective clinical outcomes such as IPSS and BPH Impact Index, while being cost-effective and versatile in its ability to treat a variety of prostate gland morphologies. This treatment option shows good lower urinary tract symptom relief, especially in small-to-moderate prostate sizes (30-80 cc). The use of convective heat transfer is unique and allows for localized treatment, avoiding damage to surrounding structures, thus providing an excellent safety profile and sexual function preservation. CONCLUSION: The current evidence on Rezum warrants its consideration as a therapeutic alternative to transurethral surgery in selected patients.

Detectable Prostate-specific antigen value between 0.01 and 0.1 ng/ml following robotic-assisted radical prostatectomy (RARP): does it correlate with future biochemical recurrence?

PURPOSE: The aim of the study is to evaluate the impact of having a nadir and persistently detectable ultrasensitive prostate-specific antigen (uPSA) between 0.01 and 0.1 ng/ml post-robot-assisted radical prostatectomy (RARP), on future biochemical recurrence (BCR). METHODS: We conducted a retrospective analysis of a prospectively maintained cohort of 1359 men who underwent RARP, between 2006 and 2019. Patients were followed with uPSA at 1, 3, 6, 9, 12, 18, 24, 30, 36 months and annually thereafter. We included patients with PSA nadir values between 0.01 and 0.1 ng/ml within 6 months of surgery and with at least 2 follow-up measurements within the same range. We divided patients based on their BCR status and analyzed uPSA changes. Multivariable Cox-regression models (CRMs) were used to analyze variables predicting BCR-free survival (BCR-FS). RESULTS: We identified 167 (12.3%) patients for analyses, with a mean follow-up time of 60.2 ± 31.4 months. In our cohort, 5-year BCR-FS rate was 86%. Overall, 32 (19.1%) patients had BCR, with a mean time to BCR of 43.7 ± 24.3 months. BCR-free patients had stable mean uPSA values ≤ 0.033 ng/ml, while patients who developed BCR showed a slowly rising trend over time, with a significant difference between groups starting at 9 months (p < 0.02). In multivariable CRMs, a rising uPSA starting at 9 months was an independent predictor of BCR (HR: 2.7; 95% CI 1.6-3.82; p = 0.013). CONCLUSION: In the present cohort, our results demonstrated that a considerable number of men have detectable uPSA values ranging between 0.01 and 0.1 ng/ml post-RARP. They can still be followed regularly to avoid patients' anxiety and salvage radiotherapy. Close follow-up is still required.

Impact of surgical wait times during summer months on the oncological outcomes following robotic-assisted radical prostatectomy: 10 years' experience from a large Canadian academic center.

PURPOSE: Most Canadian hospitals face significant reductions in operating room access during the summer. We sought to assess the impact of longer wait times on the oncological outcomes of localized prostate cancer patients following robotic-assisted radical prostatectomy (RARP). METHODS: We conducted a retrospective review of a prospectively maintained RARP database in two high-volume academic centers, between 2010 and 2019. Assessed outcomes included the difference between post-biopsy UCSF-CAPRA and post-surgical CAPRA-S scores, Gleason score upgrade and biochemical recurrence rates (BCR). Multivariable regression analyses (MVA) were used to evaluate the effect of wait times. RESULTS: A total of 1057 men were included for analysis. Consistent over a 10 year period, summer months had the lowest surgical volumes despite above average booking volumes. The lowest surgical volume occurred during the month of July (7.1 cases on average), which was 35% less than the cohort average. The longest average wait times occurred for patients booked in June (93 ± 69 days, p < 0.001). On MVA, patients booked in June had significantly more chance of having an increase in CAPRA score [HR (95% CI) 1.64 (1.02-2.63); p = 0.04] and in CAPRA risk group [HR (95% CI) 1.82 (1.04-3.19); p = 0.03]. Cohort analysis showed fair correlation between CAPRA-score difference and wait time (Pearson correlation: r = - 0.062; p = 0.044). CONCLUSION: Our cohort results demonstrate that conventional RARP wait times are significantly and consistently prolonged during summer months over the past 10 years, with worse post-RARP oncological outcomes in terms of CAPRA scores. Other compensatory mechanisms to sustain consistent yearly operative output should be considered.

Reasons to overthrow TURP: bring on Aquablation.

PURPOSE: In this review, we will discuss the state of the literature regarding Aquablation, its limitations, and opportunities for its application in the treatment of benign prostatic enlargement (BPE). METHODS: A comprehensive review of original research on Aquablation was conducted. Articles related to transurethral resection of the prostate, holmium laser enucleation of the prostate, greenlight photoselective vaporization of the prostate, and simple prostatectomy were reviewed for discussion. RESULTS: For small-medium prostates (30-80 mL), Aquablation's main advantages include better ejaculatory function and similar functional outcomes compared to TURP. For large prostates (80-150 mL), Aquablation demonstrates shorter operative time and superior ejaculatory function when compared to simple prostatectomy, HoLEP, and Greenlight PVP. In addition, Aquablation displays shorter hospital stays than simple prostatectomy. The integration of software programming and semi-automatic technology increases the reproducibility of the procedure and helps standardize overall outcomes, while also accelerating the learning curve. Its ability to preserve antegrade ejaculation makes Aquablation a very compelling option for sexually active patients. However cost and postoperative bleeding risks remain a concern. CONCLUSION: The current evidence suggests that Aquablation is a safe and effective alternative for BPE for small to large prostates. Further prospective clinical trials, with comparisons to other BPE modalities, and data from longer follow-up periods are still required.

Impact of the presence of a median lobe on functional outcomes of greenlight photovaporization of the prostate (PVP): an analysis of the Global Greenlight Group (GGG) Database.

OBJECTIVES: Previous analyses of the impact of median lobe presence on Greenlight photoselective vaporization of the prostate (PVP) outcomes were limited by their small sample size and the ability to adjust for important confounders. As such, we sought to investigate the impact of prostate median lobe presence on the operative outcomes of 180 W XPS GreenLight PVP using a large international database. METHODS: Data were obtained from the Global GreenLight Group (GGG) database which pools data of eight high-volume, experienced surgeons, from a total of seven international centers. All men with established benign prostatic hyperplasia who underwent GreenLight PVP using the XPS-180 W system between 2011 and 2019 were eligible for the study. Patients were assigned to two groups based on presence or absence of median lobes. Analyses were adjusted for patient age, prostate volume, body mass index, and American Society of Anesthesia (ASA) score. RESULTS: A total of 1650 men met the inclusion criteria. A median lobe was identified in 621 (37.6%) patients. Baseline prostate volume, patient age, and ASA score varied considerably between the two groups. In adjusted analyses, the operative and lasing time of patients with median lobes was 6.72 (95% CI 3.22-10.23; p < 0.01) minutes and 2.90 (95% CI 1.02-4.78; p < 0.01) minutes longer than the control group. Men with median lobes had similar postoperative functional outcomes to those without a median lobe except for a 1.59-point greater drop in the 12-month IPSS score compared to baseline (95% CI 0.11-3.08; p = 0.04) in the median lobe group, and a decrease in PVR after 6 months which was 46.51 ml (95% CI 4.65-88.36; p = 0.03) greater in patients with median lobes compared to men without median lobes. CONCLUSIONS: Our findings suggest that the presence of a median lobe has no clinically significant impact on procedural or postoperative outcomes for patients undergoing Greenlight PVP using the XPS-180 W system.

Global Greenlight Group: largest international Greenlight experience for benign prostatic hyperplasia to assess efficacy and safety.

INTRODUCTION: Greenlight photo-selective vaporization of the prostate (GL-PVP) has gained international acceptance as a safe and effective alternative procedure for the treatment of benign prostatic hyperplasia (BPH), especially in anticoagulated men. This descriptive analysis aims to characterize the current state of GL-PVP, pooling data from international centers. METHODS: Data from 3627 patients who underwent GL-PVP with the XPS-180 W system in seven international centers performed by eight expert surgeons between 2011 and 2019 were retrospectively analyzed. Demographic, perioperative, and postoperative data were collected, including IPSS, QoL, Qmax, PVR, and PSA, and complications. RESULTS: At baseline, median age, prostate volume, PSA, and IPSS were 70 years (interquartile range 64-77), 64 (47-90), 3.1 ng/mL (1.8-6), and 22 (19-27), respectively. Median lasing and operative time were 34 (23-48) and 62 min (46-85), respectively. Median energy use was 250.0 kJ (168.4-367.9), with 92.6% of procedures being completed with one laser fiber. In 60.1% of cases, catheter was removed on postoperative day 1 with median length of 2 days. All-cause mortality within 30 days was 0.3%. Median PSA reduction at 3 months and 60 months compared to baseline was 43.9 and 46.4%, respectively (p < 0.001). All functional outcomes (IPSS, QoL, Qmax, and PVR) were significantly improved across study period when compared to baseline (p < 0.001). For those men with longer follow-up available, the observed surgical BPH retreatment rate was 1.5% CONCLUSION: Using the largest multi-user, international database of GL-PVP, Greenlight XPS laser treatment in experienced hands is a safe, effective, and durable BPH treatment option.

Functional and perioperative outcomes in elderly men after robotic-assisted radical prostatectomy for prostate cancer.

PURPOSE: We aimed to compare postoperative functional outcomes following robotic-assisted radical prostatectomy (RARP) in elderly men with localized prostate cancer. METHODS: A retrospective review of a prospectively maintained database of men who underwent RARP between January 2007 and November 2018 was performed. Patients over 65 years of age were selected (N = 302) and then stratified by age group: 66-69 years old (N = 214) and ≥ 70 years old (N = 88). Full continence was defined as strict 0-pad per day usage. Preoperative potency included those with a Sexual Health Inventory for Men score ≥ 17. Preoperative and postoperative functional outcomes were assessed. Kaplan-Meier analysis was used to estimate time to recovery of continence in both groups. RESULTS: Both groups had comparable preoperative parameters. Continence rates at 1, 3, 6, 9, 12, 18 and 24 months in the 66-69-year-old group were 6%, 34%, 61%, 70%, 74%, 80% and 87%, respectively. Comparatively in the ≥ 70-year-old group, continence rates were significantly lower at all time points (3%, 22%, 50%, 56%, 66%, 69% and 75%, respectively). Men in the 66-69-year-old group were significantly more likely to be continent after RARP when compared to patients 70 years of age and above [(Hazards ratio (HR) 0.73; 95%confidence interval 0.54-0.97, (p = 0.035)]. CONCLUSION: Our results suggest that RARP is feasible in elderly patients. Nevertheless, elderly patients in the ≥ 70-year-old group had significantly inferior postoperative continence rates compared to patients aged 66-69 years. Such information is valuable when counselling men during preoperative RARP planning to ensure that they have realistic postoperative expectations.
