RESUMEN

INTRODUCTION: The present study analyzes the largest international GreenLight database, the Global GreenLight Group (GGG), to evaluate the functional and safety profile of GreenLight photoselective vaporization of the prostate (PVP) in octogenarians. METHODS: The GGG is a database comprised of patients that underwent GreenLight PVP from 2011 to 2019 performed by 8 experienced urologists at 7 international hospitals. Patients 80 years or older at the time of surgery were categorized as octogenarians. They were compared to a similar group of PVP patients below the age of 80. RESULTS: Among 3,648 patients, 586 men were above the age of 80. Compared to patients under the age of 80, octogenarians had larger prostates (76.0 vs 71.9 ml, p = 0.02) and a lower BMI (25.6 vs 26.7, p = 0.045). Operative time was not significantly longer in octogenarians. The improvement in functional outcomes between 80-year-old patients and control patients was not significantly different at one-year follow-up, with the exception of maximum urinary flow (Qmax) that favoured younger patients (10.3 vs 12.6 ml/s, p = 0.02). The odds of transfusion were greater for older patients [OR 8.2 (95% CI 3.6-18.9, p < 0.01)], but they were not at increased risk of hematuria. Octogenarians had higher readmission rates (23.0 vs 11.9%, p < 0.01). CONCLUSIONS: GreenLight PVP is a safe option in well-selected octogenarians in a cohort of patients treated by surgeons experienced with the technology. The odds of transfusion were higher in patients over 80, but the absolute risk remains low. The 30-day hospital readmission rate was higher in octogenarians.

RESUMEN

INTRODUCTION: GreenLight photoselective vaporization of the prostate (PVP) has gained widespread adoption as an option to traditional transurethral resection of the prostate. Prior reports expressed concern with the use of PVP in large prostates. The aim of this study was to investigate the adjusted outcomes of GreenLight PVP in men with large (≥ 80 cc) vs. small prostates (< 80 cc). METHODS: Data were obtained from the Global Greenlight Group which pools data from 7 high volume centers. Men with established benign prostatic hyperplasia who underwent GreenLight PVP using the XPS-180 W system between 2011 and 2019 were eligible and assigned into two groups based on their prostate size (≥ 80 and < 80 cc). 11 functional and perioperative covariates were collected. Analyses were adjusted for patient age and presence of median lobe. RESULTS: 3426 men met the inclusion criteria. 34.6% (n = 1187) of patients had a large prostate size. Baseline age and prostate volume were significantly different between the groups. The magnitude of absolute improvement in unadjusted international prostate symptom score was significantly greater in the large (≥ 80 cc) prostate group at 12 months, with an absolute change of 19.17 points (95% CI 18.46-19.88; p < 0.01). There was also a significant drop in PVR at both 6- (p = 0.007) and 12 months (p = 0.005). There were no significant differences in transfusion (p = 0.42), hematuria (p = 0.80), or 30-day readmission rates (p = 0.28). CONCLUSIONS: Greenlight PVP is a safe and effective alternative for patients with prostate sizes ≥ 80 cc, with durable outcomes relatively independent from prostate size.

RESUMEN

BACKGROUND AND OBJECTIVES: We examined the effect of disease-free interval (DFI) duration on cancer-specific mortality (CSM)-free survival, otherwise known as the effect of conditional survival, in surgically treated adrenocortical carcinoma (ACC) patients. METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2018), 867 ACC patients treated with adrenalectomy were identified. Conditional survival estimates at 5-years were assessed based on DFI duration and according to stage at presentation. Separate Cox regression models were fitted at baseline and according to DFI. RESULTS: Overall, 406 (47%), 285 (33%), and 176 (20%) patients were stage I-II, III and IV, respectively. In conditional survival analysis, providing a DFI of 24 months, 5-year CSM-free survival at initial diagnosis increased from 66% to 80% in stage I-II, from 35% to 66% in stage III, and from 14% to 36% in stage IV. In multivariable Cox regression models, stage III (hazard ratio [HR]: 2.38; p < 0.001) and IV (HR: 4.67; p < 0.001) independently predicted higher CSM, relative to stage I-II. The magnitude of this effect decreased over time, providing increasing DFI duration. CONCLUSIONS: In surgically treated ACC, survival probabilities increase with longer DFI duration. This improvement is more pronounced in stage III, followed by stages IV and I-II patients, in that order. Survival estimates accounting for DFI may prove valuable in patients counseling.

RESUMEN

INTRODUCTION: In this study, we sought to investigate the impact of 5-alpha reductase inhibitors (5-ARI) on the perioperative and functional outcomes of 180-Watt XPS GreenLight photovaporization of the prostate (PVP) using a large international database. MATERIALS AND METHODS: Data were obtained from the Global GreenLight Group (GGG) database, which includes eight high-volume, experienced surgeons from seven international centers.  All men with established benign prostatic hyperplasia (BPH) with known 5-ARI status who underwent GreenLight PVP using the XPS-180W system between 2011 and 2019 were eligible for the study.  Patients were assigned to two groups based on the preoperative use of 5-ARI.  Analyses were adjusted for patient age, prostate volume, and American Society of Anesthesia (ASA) score. RESULTS: We included 3,500 men, of which 1,246 (36%) had preoperative 5-ARI use.  Patients in both groups were similar with regards to age and prostate size.  On multivariable analysis, total operative time was slightly shorter (-3.26 min 95% CI: 1.20 - 5.32, p < 0.01) and required 35.6kJ less laser energy (95% CI: -48.0kJ - -23.3kJ, p < 0.01) for patients on 5ARI compared to those without 5-ARI.  However, no clinically significant difference was appreciated regarding postoperative transfusion rates [OR 0.048 (95% CI -0.82-0.91; p = 0.91)], hematuria rates [OR 0.96 (95% CI 0.72-1.3; p = 0.81)], 30-day readmission rates [OR 0.98 (95% CI 0.71-1.4; p = 0.90)], or overall functional outcomes. CONCLUSION: Our findings suggest that preoperative 5-ARI is not associated with any clinically significant different perioperative or functional outcomes for GreenLight PVP using the XPS-180W system.  There is no role for the initiation or discontinuation of 5-ARI prior to GreenLight PVP.

RESUMEN

Background and Objectives: The impact of pure histological subtypes in testicular non-seminoma germ cell tumors on survival, specifically regarding pure embryonal carcinoma, is not well established. Therefore, this study aimed to test for differences between pure embryonal carcinoma and mixed germ cell tumor patients within stages I, II and III in a large population-based database. Materials and Methods: We relied on the Surveillance, Epidemiology and End Results (SEER) database (2004-2019) to identify testicular pure embryonal carcinoma vs. mixed germ cell tumor patients. Cumulative incidence plots depicted cancer-specific mortality that represented the main endpoint of interest. Multivariable competing risks regression models tested for differences between pure embryonal carcinoma and mixed germ cell tumor patients in analyses addressing cancer-specific mortality and adjusted for other-cause mortality. Results: Of 11,223 patients, 2473 (22%) had pure embryonal carcinoma. Pure embryonal carcinoma patients exhibited lower cancer-specific mortality relative to their mixed germ cell tumor counterparts for both stage III (13.9 vs. 19.4%; p < 0.01) and stage II (0.5 vs. 3.4%, p < 0.01), but not in stage I (0.9 vs. 1.6%, p = 0.1). In multivariable competing risks regression models, pure embryonal carcinoma exhibited more favorable cancer-specific mortality than mixed germ cell tumor in stage III (hazard ratio 0.71, p = 0.01) and stage II (hazard ratio 0.11, p < 0.01). Conclusions: Pure embryonal carcinoma exhibits a more favorable cancer-specific mortality profile relative to mixed germ cell tumor in stage II and III testicular cancers. Consequently, the presence of mixed germ cell tumor elements may be interpreted as a risk factor for cancer-specific survival.

RESUMEN

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.

RESUMEN

PURPOSE: We sought to characterize the adjusted outcomes of GreenLight photoselective vaporization of the prostate (PVP) in high-medical-risk (HMR) patients using data from the largest 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. Eligible study participants underwent GreenLight PVP using the XPS-180 W system between 2011 and 2019. HMR patients were defined as patients with ASA III or greater and were compared to non-HMR patients. Analyses were adjusted for patient age and prostate volume. RESULTS: In the HMR group, patients on average were older and had smaller prostates than the non-HMR control group. Compared to non-HMR patients, transfusions occurred more frequently (2.6% vs. 0.14%, p < 0.01) and the odds of readmission were elevated [OR 2.0, (95% CI 1.4-2.8, p < 0.01)] among HMR patients. Twelve months postoperatively, HMR patients experience greater improvement in QoL than the control group [+ 0.54 (95% CI 0.07-1.0, p = 0.02)]. PVR also decreased 93.1 ml more in HMR than in non-HMR patients after 12 months (95% CI 33.6-152.6, p < 0.01). CONCLUSION: We found that GreenLight PVP is safe and effective in improving functional outcomes in higher-risk patients with severe systemic disease compared to their lower-risk counterparts. Though absolute risks remain low, GreenLight PVP is associated with higher odds of transfusion and readmission in the high-risk cohort. The findings of our study reaffirm current guidelines that propose PVP as a viable treatment option for HMR patients.

RESUMEN

Empathy has long been considered central to living a moral life. However, mounting evidence has shown that people's empathy is often biased toward (i.e., felt more strongly for) others that they are close or similar to, igniting a debate over whether empathy is inherently morally flawed and should be abandoned in efforts to strive toward greater equity. This debate has focused on whether empathy limits the scope of our morality, but little consideration has been given to whether our moral beliefs may be limiting our empathy. Across two studies conducted on Amazon's Mechanical Turk (N = 604), we investigated moral judgments of biased and equitable feelings of empathy. We observed a moral preference for empathy toward socially close over distant others. However, feeling equal empathy for all people is seen as the most morally and socially valuable approach. These findings provide new theoretical insight into the relationship between empathy and morality, and they have implications for navigating toward a more egalitarian future.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Ex vivo expansion of hematopoietic stem cell (HSCs) and progenitors may one day overcome the slow platelet engraftment kinetics associated with umbilical cord blood transplantation. Serum-free medium conditioned with osteoblasts (i.e., osteoblast-conditioned medium [OCM]) derived from mesenchymal stromal cells (MSC) was previously shown to increase cell growth and raise the levels of human platelets in mice transplanted with OCM-expanded progenitors. Herein, we characterized the cellular and molecular mechanisms responsible for these osteoblast-derived properties. Limiting dilution transplantation assays revealed that osteoblasts secrete soluble factors that synergize with exogenously added cytokines to promote the production of progenitors with short-term platelet engraftment activities, and to a lesser extent with long-term platelet engraftment activities. OCM also modulated the expression repertoire of cell-surface receptors implicated in the trafficking of HSC and progenitors to the bone marrow. Furthermore, OCM contains growth factors with prosurvival and proliferation activities that synergized with stem cell factor. Insulin-like growth factor (IGF)-2 was found to be present at higher levels in OCM than in control medium conditioned with MSC. Inhibition of the IGF-1 receptor, which conveys IGF-2' intracellular signaling, largely abolished the growth-promoting activity of OCM on immature CD34+ subsets and progenitors in OCM cultures. Finally, IGF-1R effects appear to be mediated in part by the coactivator ß-catenin. In summary, these results provide new insights into the paracrine regulatory activities of osteoblasts on HSC, and how these can be used to modulate the engraftment properties of human HSC and progenitors expanded in culture. Stem Cells 2019;37:345-356.

RESUMEN

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.

RESUMEN

Prostate cancer screening remains highly controversial in medicine. The College of Family Physicians of Canada currently endorses positions that recommend against prostate-specific antigen (PSA) screening in men of all ages, while the Canadian Urological Association recommends shared and informed decision making for PSA screening in men 50-70 years old. Unfortunately, these opposing stances have left Family Physicians responsible for interpreting the appropriate course of action for their patients. Recent studies demonstrating an increase in incidence of metastatic prostate cancer have led to our support of the Canadian Urological Association recommendations. In an attempt to facilitate initial patient investigation, this article aims to outline current prostate cancer screening recommendations, as well as the various screening modalities available. The utility of PSA-based tests, serum and non-serum biomarkers, and multiparametric magnetic resonance imaging is discussed and evaluated.

RESUMEN

For men experiencing lower urinary tract symptoms (LUTS) refractory to medical therapy, there have been numerous developments in the treatment options offered for benign prostatic hyperplasia (BPH) in the recent years. Transurethral resection of the prostate (TURP) has remained the reference standard for men with prostates sized 30 cc-80 cc, while open prostatectomy is universally guidelines-recommended in the absence of enucleation, for men with prostates larger than 80 cc-100 cc. While these techniques are effective, they have the potential for bleeding complications requiring transfusions, electrolyte abnormalities such as TURP syndrome, and often require prolonged hospitalization. GreenLight photoselective vaporization (GL-PVP) with the XPS LBO-180W system offers a minimally invasive treatment that can be carried out on essential any sized prostate gland. In addition, the GL-PVP procedure can be done as a same day discharge surgery requiring no overnight hospital admission and allows patients to continue any necessary anti-coagulants given the significantly reduced risks of bleeding complications or TURP syndrome. In 2005, the anatomic vaporization-incision technique (VIT) using the XPS LBO-180W system was described to address larger prostate volumes. VIT combines principles of traditional GL-PVP and enucleation techniques to identify the reference surgical capsule early-on into the surgery and resect portions of prostate adenoma without the need for tissue morcellation. Early studies comparing anatomic VIT to standard PVP outcomes demonstrated significant improvements of IPSS and uroflowmetry parameters, along with statistically significant greater PSA reduction at 6 months, particularly in prostate volumes greater than 80 cc. The objective of this article is to detail our surgical approach to the anatomic GreenLight laser vaporization-incision technique using the XPS LBO-180W system, based on extensive personal experience with both enucleation and vaporization techniques using various laser technologies. Standardization of the VIT based on proper cystoscopy, knowledge of prostate anatomy with preoperative ultrasound, and routine technique is essential to developing consistent, reproducible and optimal surgical outcomes.

RESUMEN

INTRODUCTION: Abdominal wall hematoma (AWH) is a self-resolving, yet common complication from the insertion of trocars during laparoscopic surgery. Particularly, its appearance may increase patient anxiety and may reduce overall surgical satisfaction. MATERIALS AND METHODS: In a retrospective study analyzing data from 724 robot-assisted radical prostatectomy cases (RARP), trocar insertion sites were examined on postoperative day 7 with Foley removal for AWH. AWH was defined by a sizable collection of blood below the skin as a result of the surgery. The AccuVein AV400 system was utilized to generate real-time images of venous structures beneath the skin. Comparative outcomes were performed with a series of 114 men where the AccuVein AV400 device was applied over trocar insertion markings to help modify port placement. RESULTS: The pre-incision imaging of the AccuVein system modified port placement in 74 of 114 cases (65%), and reduced AWH from 8.8% to 2.6% (p = 0.03) as compared to transabdominal illumination. Port placement adjustments were most prevalent in the lateral regions of the abdomen, prompting attention for lateral trocar insertion to avoid vessels such as the thoracoepigastric veins. Notably, the body mass index (BMI) of patients experiencing AWH who received the pre-incision imaging of AccuVein was significantly higher than patients receiving standard transabdominal illumination (34.2 and 27.9 kg/m² respectively; p = 0.02). CONCLUSION: The AccuVein AV400 device appears to be an effective adjuvant for decreasing rates of AWH during lower abdominal wall trocar insertion, though its effectiveness is limited in patients with extreme BMI. Additionally, special attention should be directed towards trocar insertion in the lateral regions of the abdomen.

RESUMEN

As the threat of climate change looms large, and we experience first-hand the impacts of rapid global warming, researchers and clinicians emphasize the need to better understand the impact of these changes on our mental health. Existing research suggests that coping with and emotional reactions to climate change can promote action to adapt to and mitigate the impacts of climate change and reduce its negative impacts to one's mental health. In this pre-registered study (N = 771) we examined whether people who display extreme intergenerational concern would also constructively cope with climate change. Empirically-identified individuals showing high intergenerational concern reported more problem-focused and meaning-based coping, and less avoidant coping strategies with climate change. Further, even though they felt guilty, angry, sorrowful and isolated, these individuals also felt hopeful about the future. These effects were explained by increased concerns about one's legacy and higher access to environmental cognitive alternatives. By instilling values that highlight intergenerational concern as a key priority, we could thus not only increase pro-climate action, but also help individuals actively and constructively cope with changes produced by climate change.

RESUMEN

Does empathy necessarily impede equity in altruism? Emerging findings from cognitive and affective science suggest that rationality and empathy are mutually compatible, contradicting some earlier, prominent arguments that empathy impedes equitable giving. We propose alternative conceptualizations of relationships among empathy, rationality, and equity, drawing on interdisciplinary advances in altruism research.

RESUMEN

Individuals and governments often fail to take action to address climate change owing largely to widespread politicization of the issue and related discourse. In response to recent appeals for non-partisan approaches to pro-environmentalism, we propose that highlighting one's responsibility to future generations (RFG) could offer promise across the political spectrum. We argue that RFG may be effective because it is widely endorsed, uncorrelated with demographic indicators and less tied to political ideology compared to other forms of responsibility, such as personal responsibility for climate change mitigation. Across six main and seven supplementary studies (N = 161,633), we provide evidence for these claims. RFG is not only widely endorsed across countries and demographic groups but it also significantly predicts various measures of pro-environmental behaviour, both in correlational and pre-registered experimental contexts. These findings confirm established effects, reconcile inconsistencies and suggest prioritizing intergenerational responsibility may effectively reshape climate change narratives for the most resistant parties.

RESUMEN

BACKGROUND: It is unknown whether previously reported other-cause mortality (OCM) advantage of partial cytoreductive nephrectomy (PCN) vs. radical cytoreductive nephrectomy (RCN) still applies to contemporary clear cell metastatic renal cell carcinoma (ccmRCC) patients. MATERIALS AND METHODS: We relied on the Surveillance, Epidemiology and End Results (SEER) database (2004-2019) to identify ccmRCC patients treated with PCN and RCN. Temporal trends of PCN rates within the SEER database were tabulated. After propensity score matching (PSM), cumulative incidence plots depicted 5-year OCM and cancer-specific mortality (CSM) of PCN and RCN patients. Multivariable Cox regression models tested for differences between PCN vs. RCN. RESULTS: Of 5149 study patients, 237 (5%) underwent PCN vs. 4912 (95%) RCN. In the SEER database 2004 to 2019, rates of PCN in ccmRCC patients increased from 3.0% to 8.0% (estimated annual percent change [EAPC]: 3.0%; P = .04). After PSM, 5-year OCM rates were 2.4 vs. 7.5% for respectively PCN vs. RCN patients (P = .036). 5-year CSM rates were 50.8 vs. 53.6% for respectively PCN and RCN patients (P = .57). In multivariable Cox regression models, PCN was associated with lower OCM (Hazard Ratio (HR): 0.39; 95% confidence interval (CI): 0.18-0.84; P = .02) but did not affect CSM rates (HR: 0.99; 95% CI: 0.76-1.29; P = .96). CONCLUSIONS: We confirm the existence of OCM advantage after PCN vs. RCN in contemporary ccmRCC patients.
