Differential expression of metabolic enzymes in testicular germ cell tumors: The impact of glycolytic metabolism in embryonal carcinoma histotype.

Background: Testicular germ cell tumors are the most common solid malignancies in young men, with increasing incidence worldwide. Broadly classified into seminomas and non-seminomas, they exhibit distinct biological behaviors and responses to treatment. Although metabolic reprogramming is an acknowledged cancer hallmark, metabolic pathways in testicular germ cell tumors remain poorly understood.

Death-birth adaptive dynamics: modeling trait evolution.

Here, we derive stochastic adaptive dynamics from the microscopic death-birth process by explicitly modeling the trait variation from offspring to parent in each reproductive event, thereby accounting for a highly polymorphic population. This generalization enables the construction of a quantitative model that can be subjected to empirical validation. Our mathematical analysis furnishes a formula for estimating the trait variation in the reproductive step by exclusively observing the current trait variation in the population.

Orchiectomy after torsion testis: Simultaneous prosthesis placement versus staged procedures.

Background/purpose: Testicular torsion(TT) with unsalvageable testis has a significant psychosocial impact. Orchiectomy can be performed with optional testicular prosthesis(TP) placement, commonly deferred(dTP). Orchiectomy and simultaneous testicular prosthesis placement(sTP) may be a feasible and safe option and has been implemented in our department since 2018.

It holds significance for public health by identifying potential zoonotic risks. We aimed to describe the occurrence of gastrointestinal parasites in captive wild birds from a Conservation Institute in Brazilian Cerrado biome.

Real‑world retrospective study of early‑stage prostate cancer at a Portuguese Comprehensive Cancer Centre: The PEarlC study.

Despite the high prevalence of localised prostate cancer (LPC) and locally advanced prostate cancer (LAPC), evidence on the characteristics of patients, treatments and clinical outcomes stratified by disease risk is limited. The PEarlC study was conducted to characterise a cohort of patients with early-stage prostate cancer that included real-world clinical outcomes. Retrospective data from a cohort of patients diagnosed with LPC/LAPC between 2015 and 2017 and followed up until December 2020 at a Portuguese comprehensive cancer centre (IPO Porto) was analysed.

Gastrointestinal Helminths in Wild Felids in the Cerrado and Pantanal: Zoonotic Bioindicators in Important Brazilian Biomes.

Environmental changes in the Brazilian Pantanal and Cerrado facilitate the spread of parasitic diseases in wildlife, with significant implications for public health owing to their zoonotic potential. This study aimed to examine the occurrence and diversity of gastrointestinal parasites in wild felids within these regions to assess their ecological and health impacts. We collected and analyzed helminth-positive samples from 27 wild felids using specific taxonomic keys.

EHMT2/G9a and EZH2: Epimarkers in testicular germ cell tumors.

Background: Testicular germ cell tumors remain the most frequent solid malignancies in young males. Despite excellent prognosis, the fact that only 60% of patients at diagnosis have elevated serum tumor markers (dependent on stage and histology) and the poor quality of life of patients who develop resistance to chemotherapy cannot be neglected. Consequently, it is mandatory to bring out novel biomarkers.

[Analysis of indigenous dengue in an infectious diseases Hospital in Buenos Aires, Argentina].

Introduction: Dengue is a disease transmitted by mosquitoes of the Aedes genus; this has presented a historical increase in cases in South America, which represents a public health problem. From the Febrile Emergency Unit (UFU) of Hospital Muñiz, the laboratory results were analyzed and the circulating serotype was identified at the level of the Autonomous City of Buenos Aires (CABA), confirming the proportion of indigenous cases, recording symptoms and epidemiology. The objective of this analysis is to highlight the increase in indigenous cases of dengue in CABA.

Stochastic evolution of bad memes.

Dawkins introduced a groundbreaking concept suggesting that humans, similar to other animals, operate as gene-propagating machines. Following in his footsteps, Blackmore posits that humans might distinguish themselves from other animals by also serving as specialized meme-replicating machines. Here we introduce a mathematical model that examines the impact of social conformity on the propagation of bad memes (memes with low intrinsic appeal).

Separate gut-brain circuits for fat and sugar reinforcement combine to promote overeating.

Food is a powerful natural reinforcer that guides feeding decisions. The vagus nerve conveys internal sensory information from the gut to the brain about nutritional value; however, the cellular and molecular basis of macronutrient-specific reward circuits is poorly understood. Here, we monitor in vivo calcium dynamics to provide direct evidence of independent vagal sensing pathways for the detection of dietary fats and sugars.

Association between sociodemographic and clinical features, health behaviors, and health literacy of patients with prostate cancer and prostate cancer prognostic stage.

Patient characteristics may influence access and acceptance of Prostate Specific Antigen test, and therefore, the timing of prostate cancer (PCa) diagnosis. A group of 361 patients from a cohort (n = 451) diagnosed with PCa in 2018-2020 at the Portuguese Institute of Oncology of Porto was evaluated before treatment, using a structured interview, the Medical Term Recognition Test, and the EORTC Quality of Life Questionnaire QLQ-PR25. PCa prognostic stages (I, II, III, IV) were attributed according to the American Joint Committee on Cancer eighth edition.

OncoUroMiR: Circulating miRNAs for Detection and Discrimination of the Main Urological Cancers Using a ddPCR-Based Approach.

The three most common genitourinary malignancies (prostate/kidney/bladder cancers) constitute a substantial proportion of all cancer cases, mainly in the elderly population. Early detection is key to maximizing the patients' survival, but the lack of highly accurate biomarkers that might be used through non-/minimally invasive methods has impaired progress in this domain. Herein, we sought to develop a minimally invasive test to detect and discriminate among those urological cancers based on miRNAs assessment through ddPCR.
