Regional Hereditary Cancer Program in Chile: A scalable model of genetic counseling and molecular diagnosis to improve clinical outcomes for patients with hereditary cancer across Latin America.

Background: Breast cancer is a leading cause of cancer-related mortality worldwide, with hereditary forms accounting for approximately 10% of cases. In Chile, significant gaps exist in genetic counseling and testing, particularly within the public health system. This study presents the implementation and outcomes of the first regional hereditary cancer program in the Maule region of Chile, aimed at improving detection and management of hereditary breast cancer.

Secondary Myiasis in an Immunocompetent Patient With Severe Chromoblastomycosis.

This is the case of chronic chromoblastomycosis (CBM) in a 61-year-old male from the Dominican Republic (DR) with extensive cutaneous eruptions over multiple areas of the body including bilateral lower extremities and the flank extending to the back. A 61-year-old male with a history of morbid obesity, chronic kidney disease stage III, and well-controlled hypertension presented to the family medicine clinic for the evaluation of chronic painful skin lesions on his legs and torso. The lesions began 19 years prior, following a flood in the Dominican Republic (DR) where he was living at the time.

Tissue-Specific Effects of Aging on Repeat-Mediated Mutation Hotspots In Vivo.

Aging constitutes complex and dynamic alterations in molecular and physiological processes and is associated with numerous disorders, in part due to increased genetic instability. The aging population is projected to double by 2050, underscoring the urgent need to better understand the relationships between aging and age-related disorders. Repetitive DNA elements are intrinsic sources of genetic instability and have been found to co-localize with mutation hotspots in human cancer genomes.

A third strand for protein-DNA interactions.

A method has been developed based on proximity labelling that detects the interaction of specific proteins with endogenous triplex DNA sequences formed in live cells — significantly expanding the catalogue of putative proteins that interact with these DNA structures.

Sirtuin Expression in Insulin-Sensitive Tissues of Rats with Impaired Glucose Tolerance is not Affected by Resistance Training or Zinc Supplementation.

While physical activity and zinc supplementation have shown benefits in diabetes management, little is known about their effect on less severe glucose homeostasis disorders, such as impaired glucose tolerance. On the other hand, sirtuins have an important role in glucose metabolism and insulin sensitivity, but to date, there is no information about the impact of zinc supplementation or physical activity on their regulation in individuals with impaired glucose homeostasis. The aim of this study was to assess the effect of supplemental zinc, muscle-resistance training, and their combination on the expression of selected sirtuins in insulin-sensitive tissues of rats with impaired glucose tolerance.
