Phosphorylation of 'SDT-like' motifs in ATRX mediates its interaction with the MRN complex and is important for ALT pathway suppression.

Approximately 10-15% of human cancers are telomerase-negative and maintain their telomeres through a recombination-based process known as the alternative lengthening of telomeres (ALT) pathway. Loss of the alpha-thalassemia/mental retardation, X-linked (ATRX) chromatin remodeller is a common event in ALT-positive cancers, but is generally insufficient to drive ALT induction in isolation. We previously demonstrated that ATRX binds to the MRN complex, which is also known to be important in the ALT pathway, but the molecular basis of this interaction remained elusive.

Hopkins Syndrome: An Uncommon Cause of Weakness in Intensive Care Unit.

Background: Hopkins syndrome is a rare polio-like syndrome, with an incompletely understood pathophysiology, that affects children after asthma crisis.

Methods: A 10-year-old girl was admitted to the intensive care unit following a severe asthma attack, requiring mechanical ventilation for a period of five days. After regaining consciousness, the patient exhibited development of asymmetric flaccid paraparesis.

Assessment of the adherence to perioperative nutritional care protocols in Brazilian hospitals: The PreopWeek study.

Objectives: The study (PreopWeek) aimed to assess the perioperative nutritional care for major surgical patients in Brazilian hospitals, focusing on adherence to emerging multimodal protocols like Enhanced Recovery After Surgery and Acceleration of Total Postoperative Recovery.

Methods: An observational cross-sectional study was conducted in Brazilian hospitals enrolled voluntarily from June 19 to June 23, 2023 (convenience sample). Data were collected through patient interviews and medical records review.

Understanding American tegumentary leishmaniasis in urban Montes Claros, Brazil: insights from clinical, immunological and therapeutic investigations.

The challenge of American tegumentary leishmaniasis (ATL) continues in Brazil, presenting a persistent public health issue despite initiatives aimed at public outreach, vector control and health education. To gain a deeper understanding of this disease, a study was conducted in an endemic region located in the northern region of the state of Minas Gerais, Brazil. The study monitored 30 resident patients diagnosed with ATL, using serum samples from 6 healthy individuals as controls.
