The single-stranded DNA-binding factor SUB1/PC4 alleviates replication stress at telomeres and is a vulnerability of ALT cancer cells.

To achieve replicative immortality, cancer cells must activate telomere maintenance mechanisms. In 10 to 15% of cancers, this is enabled by recombination-based alternative lengthening of telomeres pathways (ALT). ALT cells display several hallmarks including heterogeneous telomere length, extrachromosomal telomeric repeats, and ALT-associated PML bodies.

The impact of a caregiver's chronic illness on childhood psychosocial functioning.

Introduction: Prolonged activation of the body's stress response from chronic exposure to adverse stressors may have a significant impact on lifelong psychosocial functioning. Screening for the impact of prolonged adversity in childhood has become an integral component of pediatric care. While past research has separately explored the impact of caregiver chronic illness and caregiver toxic stress on children, the relationship between caregiver chronic illness disability burden, caregiver parental toxic stress, and their child's psychosocial functioning is not well understood.

Pernicious Pouch of Problems: A Challenging Case of Massive Hemorrhage Secondary to Jejunal Diverticular Bleeding.

Small bowel (SB) diverticulosis is an uncommon diagnosis and a rare cause of gastrointestinal (GI) bleeding. A particularly rare form of SB diverticular disease, jejunal diverticulosis, is usually discovered due to complications, such as hemorrhage, obstruction, or perforation. Owing in part to its rarity, jejunal diverticular bleeding can be difficult to identify and treat, resulting in increased morbidity and mortality.

Eligibility for Transcatheter Tricuspid Valve Interventions in Patients With Tricuspid Regurgitation.

Background: It remains unclear what proportion of patients with tricuspid regurgitation (TR) are suitable candidates for transcatheter tricuspid valve intervention (TTVI) in clinical practice.

Objectives: The aim of this study was to ascertain the prevalence of eligibility for tricuspid transcatheter edge-to-edge repair (T-TEER) and transcatheter tricuspid valve replacement (TTVR) devices among patients with TR.

Methods: The tricuspid valve anatomy of all consecutive patients with TR who were considered for TTVI in local heart team conferences was retrospectively reviewed.
