Do Adolescents Adopt the Prosocial Behaviors of the Classmates They Like? A Social Network Analysis on Prosocial Contagion.

While the influence of high-status peers on maladaptive behaviors is well-documented, socialization processes of prosocial behavior through high-status peers remain understudied. This study examined whether adolescents' prosocial behavior was influenced by the prosocial behavior of the peers they liked and whether this effect was stronger when the peers they liked were also well-liked by their classmates. Three waves of data, six months apart, were collected among Chilean early adolescents who completed peer nominations and ratings at Time 1 (n = 294, Mage = 13.

Parenchymal obliteration by renal masses: Functional and oncologic implications.

Objectives: Most renal tumors merely displace nephrons while others can obliterate parenchyma in an invasive manner. Substantial parenchymal volume replacement (PVR) by renal cell carcinoma (RCC) may have oncologic implications; however, studies regarding PVR remain limited. Our objective was to evaluate the oncologic implications associated with PVR using improved methodology including more accurate and objective tools.

The role of academic performance, prosocial behaviour and friendships on adolescents' preferred studying partners: A longitudinal social network analysis.

Background: Peers constitute an important developmental context for adolescent academic behaviour providing support and resources to either promote or discourage attitudes and behaviours that contribute to school success. When looking for academic help, students may prefer specific partners based on their social goals regarding academic performance.

Aims: Based on the social goals for wanting to achieve academically (e.

Practical Prediction of New Baseline Renal Function After Partial Nephrectomy.

Background: Partial nephrectomy (PN) is generally preferred for localized renal masses due to strong functional outcomes. Accurate prediction of new baseline glomerular filtration rate (NBGFR) after PN may facilitate preoperative counseling because NBGFR may affect long-term survival, particularly for patients with preoperative chronic kidney disease. Methods for predicting parenchymal volume preservation, and by extension NBGFR, have been proposed, including those based on contact surface area (CSA) or direct measurement of tissue likely to be excised/devascularized during PN.

Cross-cultural invariance of the Spanish version of the COVID-19 Assessment Scorecard to measure the perception of government actions against COVID-19 in Latin America.

Objectives: The present study aimed to evaluate the measurement invariance of a general measure of the perception of governmental responses to COVID-|19 (COVID-SCORE-10) in the general population of 13 Latin American countries.

Methods: A total of 5780 individuals from 13 Latin American and Caribbean countries selected by non-probabilistic snowball sampling participated. A confirmatory factor analysis was performed and the alignment method was used to evaluate invariance.

Holmium Laser Enucleation of the Prostate vs Transvesical Single-port Robotic Simple Prostatectomy for Large Prostatic Glands.

Objective: To compare the perioperative outcomes of transvesical single-port robotic simple prostatectomy (SP-RASP) and holmium laser enucleation of the prostate (HoLEP).

Materials And Methods: A retrospective review was performed of patients undergoing SP-RASP and HoLEP from 2019 to 2022 with preoperative prostatic volume (PPV) >80 cm. Percent of prostate adenoma removed (%PAR) was estimated by specimen weight normalized by PPV.

Point of care parenchymal volume analyses to estimate split renal function and predict functional outcomes after radical nephrectomy.

Accurate prediction of new baseline GFR (NBGFR) after radical nephrectomy (RN) can inform clinical management and patient counseling whenever RN is a strong consideration. Preoperative global GFR, split renal function (SRF), and renal functional compensation (RFC) are fundamentally important for the accurate prediction of NBGFR post-RN. While SRF has traditionally been obtained from nuclear renal scans (NRS), differential parenchymal volume analysis (PVA) via software analysis may be more accurate.

Is the meaning of subjective well-being similar in Latin American countries? A cross-cultural measurement invariance study of the WHO-5 well-being index during the COVID-19 pandemic.

Background: There is an urgent need to assess changes in well-being on a multinational scale during the COVID-19 pandemic, thus culturally valid scales must be available.

Methods: With this in mind, this study examined the invariance of the WHO well-being index (WHO-5) among a sample of 5183 people from 12 Latin Americans countries (Argentina, Bolivia, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Mexico, Paraguay, Peru, and Uruguay).

Results: The results of the present study indicate that the WHO-5 is strictly invariant across samples from different Latin American countries.

Comprehensive Management of Renal Masses in Solitary Kidneys.

Background: A renal mass in a solitary kidney (RMSK) has traditionally been managed with partial nephrectomy (PN), although radical nephrectomy (RN) is occasionally required. Most RMSK studies have focused on patients for whom PN was achieved.

Objective: To provide a comprehensive analysis of the management strategies/outcomes for an RMSK and address knowledge deficits regarding this challenging disorder.

Celebrating 's 50 years: trends, absences, and opportunities.

Unlabelled: The journal, (HE), was established in 1972 and is currently one of the leading international journals in higher education studies. By using bibliometric techniques, a systematic review, and a social network analysis, this review article provides an overview of the main patterns of publications in during its history. The findings show that (i) the volume of articles has been continuously increasing, with a particular marked uplift since 2007; (ii) while single-authored articles have dominated the publication pattern, collaborative articles have shown a particular growth over the last decade; (iii) the USA, the UK, and Australia have dominated the journal in terms of the number of articles, international collaboration, and the most prolific authors; (iv) while Chinese authors have become more evident, there has been a near-absence of contributions from Latin America, Eastern Europe, and most of Africa; (v) in the entire history of , there has been a gender imbalance (in favour of male authors) across the most cited articles, but this pattern has changed in the last decade and; (vi) both teaching and learning and system policy have been key research themes in the journal although internationalisation and the student experience have recently gained traction.

Network analysis of the relationships between conspiracy beliefs towards COVID-19 vaccine and symptoms of fear of COVID-19 in a sample of latin american countries.

The present study examined how conspiracy beliefs about COVID-19 vaccines specifically relate to symptoms of fear of COVID-19 in a sample of four South American countries. A total of 1785 people from Bolivia, Colombia, Ecuador, and Peru participated, responding to a sociodemographic survey, the Fear of COVID-19 scale (FCV-19 S) and the Vaccine Conspiracy Beliefs Scale-COVID-19 (VCBS-COVID-19). Network analysis identified the most important symptoms of fear and conspiracy beliefs about COVID-19 vaccines (nodes) and the associations between them (edges).

Optimizing prediction of new-baseline glomerular filtration rate after radical nephrectomy: are algorithms really necessary?

Introduction: Radical nephrectomy (RN) is an important consideration for the management of localized renal-cell-carcinoma (RCC) whenever the tumor appears aggressive, although reduced renal function is a concern. Split-renal-function (SRF) in the contralateral kidney and postoperative renal functional compensation (RFC) are fundamentally important for the accurate prediction of new baseline GFR (NBGFR) post-RN. SRF can be estimated either from nuclear renal scans (NRS) or from preoperative imaging using parenchymal-volume-analysis (PVA).

Design and Cross-Cultural Invariance of the COVID-19 Vaccine Conspiracy Beliefs Scale (COVID-VCBS) in 13 Latin American Countries.

Aims: Over the past 2 years, the vaccine conspiracy beliefs construct has been used in a number of different studies. These publications have assessed the determinants and outcomes of vaccine conspiracy beliefs using, in some cases, pooled data from different countries, and compared the results across these contexts. However, studies often do not consider measurement invariance as a necessary requirement for comparative analyses.

What Is the Support for Conspiracy Beliefs About COVID-19 Vaccines in Latin America? A Prospective Exploratory Study in 13 Countries.

Conspiracy theories about COVID-19 began to emerge immediately after the first news about the disease and threaten to prolong the negative impact of the COVID-19 pandemic by limiting people's willingness of receiving a life-saving vaccine. In this context, this study aimed to explore the variation of conspiracy beliefs regarding COVID-19 and the vaccine against it in 5779 people living in 13 Latin American countries (Argentina, Bolivia, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Mexico, Paraguay, Peru, Uruguay and Venezuela) according to sociodemographic variables such as gender, age, educational level and source of information about COVID-19. The study was conducted during the COVID-19 pandemic between September 15 and October 25, 2021.

Split Renal Function Is Fundamentally Important for Predicting Functional Recovery After Radical Nephrectomy.

Unlabelled: While partial nephrectomy (PN) is generally preferred for localized renal cell carcinoma (RCC), radical nephrectomy (RN) is occasionally required. A new-baseline glomerular filtration rate (NBGFR) >45 ml/min/1.73 m after kidney cancer surgery is associated with strong survival outcomes.

Pathologic Findings and Management of Renal Mass in Horseshoe Kidneys.

Objectives: To evaluate the management, surgical outcomes, and pathological findings in patients with tumor in a horseshoe-kidney (HK). HK patients present unique challenges due to aberrant vascular anatomy and risk of renal insufficiency. We hypothesized that many tumors in this setting may be indolent or benign.

Cross-cultural validation of the new version of the in twelve Latin American countries.

Unlabelled: The Coronavirus Anxiety Scale (CAS) was recently developed to assess dysfunctional anxiety related to COVID-19. Although different studies reported that the CAS is psychometrically sound, it is unclear whether it is invariant across countries. Therefore, the present study aimed to examine the measurement invariance of the CAS in twelve Latin American countries (Argentina, Bolivia, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Mexico, Paraguay, Peru, and Uruguay).

What Happens to the Preserved Renal Parenchyma After Clamped Partial Nephrectomy?

Background: Most partial nephrectomies (PNs) are performed with hilar occlusion to reduce blood loss and optimize visualization. However, the histologic status of the preserved renal parenchyma years after PN is unknown.

Objective: To compare the histologic chronic kidney disease (CKD) score of renal parenchyma before and years after PN, and to explore factors associated with CKD-score increase and glomerular filtration rate (GFR) decline.

Predicting GFR after radical nephrectomy: the importance of split renal function.

Purpose: To evaluate a conceptually simple model to predict new-baseline-glomerular-filtration-rate (NBGFR) after radical nephrectomy (RN) based on split-renal-function (SRF) and renal-functional-compensation (RFC), and to compare its predictive accuracy against a validated non-SRF-based model. RN should only be considered when the tumor has increased oncologic potential and/or when there is concern about perioperative morbidity with PN due to increased tumor complexity. In these circumstances, accurate prediction of NBGFR after RN can be important, with a threshold NBGFR > 45 ml/min/1.

Cross-Cultural Validation of a New Version in Spanish of Four Items of the (PCIBS) in Twelve Latin American Countries.

The invariance of the Preventive COVID-19 Infection Behaviors Scale (PCIBS) was evaluated in 12 Latin American countries (Argentina, Bolivia, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Mexico, Paraguay, Peru, and Uruguay). A total of 5183 people from the aforementioned countries participated, selected using the snowball sampling method. Measurement invariance was assessed by multigroup confirmatory factor analysis (MG-CFA) and Multi-Group Factor Analysis Alignment (CFA-MIAL).

Parenchymal Volume Replacement by Renal Cell Carcinoma Prior to Intervention: Predictive Factors and Functional Implications.

Objective: To analyze predictors, extent and functional implications associated with renal parenchymal volume replacement (PVR) by renal cell carcinoma (RCC) prior to intervention. This phenomenon is well-recognized yet not adequately studied, and, if severe, can influence management.

Materials And Methods: A retrospective review was performed of partial nephrectomy (PN) and radical nephrectomy (RN) patients with available preoperative nuclear-renal-scan and imaging demonstrating solitary RCC with normal contralateral kidney.

The role of perspective-taking and low social class prejudice on cross-ethnic friendship formation.

Cross-ethnic friendships offer a unique opportunity for improving intergroup relations and reduce prejudice, yet ethnic segregation of friendship networks is often seen as a major obstacle to the integration of immigrant students in educational contexts. This article examines the role of perspective-taking abilities and prejudice towards low social class peers on the probability of cross-ethnic friendships in a sample of 242 students from five multicultural classrooms in Chile (M = 12.3; SD = 0.
