Effects of urbanization and accessibility to sanitation services on water quality in urban streams in Uruguay.

The world's urban population is growing rapidly, and threatening natural ecosystems, especially streams. Urbanization leads to stream alterations, increased peak flow frequencies, and reduced water quality due to pollutants, morphological changes, and biodiversity loss, known as the urban stream syndrome. However, a shift towards recognizing urban streams as valuable natural systems is occurring, emphasizing green infrastructure and nature-based solutions.

Oncologic Outcomes in Young Adults With Kidney Cancer Treated During the Targeted Therapy Era.

Background: The objective of this study was to determine the outcomes of young adults with kidney cancer treated during the targeted therapy era and evaluate the impact of young age on survival.

Materials And Methods: We reviewed the records from 445 patients younger than 55 years with kidney cancer at a single institution from 2006 to 2017. Overall survival (OS) and recurrence-free survival were estimated with the Kaplan-Meier method and log-rank test.

Impact of bilateral biopsy-detected prostate cancer on an active surveillance population.

Background: To assess factors that can predict active surveillance (AS) failure on serial transrectal ultrasound guided biopsies in patients with low-risk prostate cancer.

Methods: We evaluated the records of 144 consecutive patients enrolled in AS between 2007 and 2014 at a single academic institution. Low risk inclusion criteria included PSA < 10 ng/ml, cT1c or cT2a, Grade Group (GG) 1, < 3 positive cores, and < 50% tumor in a single core with the majority having a PSA density of < 0.

Robot-assisted extended pelvic lymph node dissection in prostate cancer. When and how?

Objective: To review the literature evaluating the role of the extended pelvic lymph node dissectione PLND during robot assisted radical prostatectomy (RARP) in the management of PCa patients, as well as the preoperative clinic pathologic factors that predict lymph node metastases (LNM). The technique and current outcomes of robotic ePLND will be presented.

Methods: Medline®/Pubmed® were searched up to august 2018 to find comparative studies of different anatomic limits of pelvic lymph node dissection (PLND) during RARP, open or pure laparoscopic surgery that reported number of nodes retrieved, oncologic outcomes and complications.

Clinical and pathologic factors predicting reclassification in active surveillance cohorts.

The incidence of small, lower risk well-differentiated prostate cancer is increasing and almost half of the patients with this diagnosis are candidates for initial conservative management in an attempt to avoid overtreatment and morbidity associated with surgery or radiation. A proportion of patients labeled as low risk, candidates for Active Surveillance (AS), harbor aggressive disease and would benefit from definitive treatment. The focus of this review is to identify clinicopathologic features that may help identify these less optimal AS candidates.

The current situation in hip arthroscopy.

Hip arthroscopy is an evolving surgical technique that has recently increased in popularity.Although femoroacetabular impingement was an important launch pad for this technique, extra-articular pathology has been described through hip endoscopy.Good clinical results in the medium term will allow improvements in this technique and increase its indications.

Crocodiles in the Sahara desert: an update of distribution, habitats and population status for conservation planning in Mauritania.

Background: Relict populations of Crocodylus niloticus persist in Chad, Egypt and Mauritania. Although crocodiles were widespread throughout the Sahara until the early 20(th) century, increased aridity combined with human persecution led to local extinction. Knowledge on distribution, occupied habitats, population size and prey availability is scarce in most populations.
