Clinical outcomes of stage IIA/IIB seminoma treated with radiotherapy and chemotherapy: should regional therapy be considered the preferred treatment approach?

Purpose: The optimal management of patients with de novo clinical stage IIA/B (CSIIA/B) or relapsed CSIIA/B (Rel-CSIIA/B) seminoma remains debated due to a lack of randomized evidence. Herein, we sought to evaluate outcomes following radiotherapy and chemotherapy in this setting.

Materials And Methods: A prospectively maintained single-institutional database was retrospectively queried for patients diagnosed between 1995-2016 with de novo or Rel-CSIIA/B.

Bosniak Classification of Cystic Renal Masses Version 2019: Proportion of Malignancy by Class and Subclass-Systematic Review and Meta-Analysis.

Bosniak classification version 2019 (v2019) was a major revision to version 2005 (v2005) that defined cystic renal mass subclasses based on wall or septa features. To determine the proportion of malignancy within cystic renal masses stratified by Bosniak classification v2019 class and feature-based subclass. MEDLINE and EMBASE databases were searched on July 24, 2023 for studies published in 2019 or later that reported cystic renal masses that underwent renal-mass CT or MRI, were assessed using Bosniak v2019, and had a reference standard (histopathology indicating benignity or malignancy or ≥5-year imaging follow-up indicating benignity).

Gene-editing in patient and humanized-mice primary muscle stem cells rescues dysferlin expression in dysferlin-deficient muscular dystrophy.

Dystrophy-associated fer-1-like protein (dysferlin) conducts plasma membrane repair. Mutations in the DYSF gene cause a panoply of genetic muscular dystrophies. We targeted a frequent loss-of-function, DYSF exon 44, founder frameshift mutation with mRNA-mediated delivery of SpCas9 in combination with a mutation-specific sgRNA to primary muscle stem cells from two homozygous patients.

Single-neuron spiking variability in hippocampus dynamically tracks sensory content during memory formation in humans.

During memory formation, the hippocampus is presumed to represent the content of stimuli, but how it does so is unknown. Using computational modelling and human single-neuron recordings, we show that the more precisely hippocampal spiking variability tracks the composite features of each individual stimulus, the better those stimuli are later remembered. We propose that moment-to-moment spiking variability may provide a new window into how the hippocampus constructs memories from the building blocks of our sensory world.

Status of Serum Magnesium among Patients with Chronic Kidney Disease.

Chronic kidney disease (CKD) is one of the largest public health issues and the major cause of death worldwide. Due to an increase in the incidence of systemic diseases like diabetes and hypertension, which are the two main causes of CKD and kidney damage, the prevalence of CKD is rising globally. Chronic Kidney Disease results in mineral disorders as well as profound lipid disorders due to improper balancing of the mineral & hormone levels in the body.
