Article Synopsis
  • TNG908 is a clinical-stage inhibitor targeting PRMT5, utilizing a unique binding mechanism that exploits the loss of the MTAP gene commonly found in various cancers.
  • It specifically inhibits PRMT5 in cancer cells lacking MTAP, which occurs in 10-15% of human cancers and could lead to more effective treatments compared to earlier drugs.
  • Ongoing Phase I/II trials are investigating the effectiveness of TNG908 in patients with MTAP-null tumors, including glioblastoma, suggesting a promising future for this therapy in multiple cancer types, particularly those affecting the brain.

The immune system is a key player in the onset and progression of neurodegenerative disorders. While brain resident immune cell-mediated neuroinflammation and peripheral immune cell (eg, T cell) infiltration into the brain have been shown to significantly contribute to Alzheimer's disease (AD) pathology, the nature and extent of immune responses in the brain in the context of AD and related dementias (ADRD) remain unclear. Furthermore, the roles of the peripheral immune system in driving ADRD pathology remain incompletely elucidated.

Background: Intracerebral hemorrhage (ICH) is associated with a large hematoma that causes compression, increased intracranial pressure (IICP), midline shift, and brain herniation, and may ultimately lead to death. Urgent surgical removal of the large hematoma can ameliorate these injuries, which would be life-saving, but has not improved clinical outcome. A suitable animal model that mimics the clinically relevant human severe ICH injury requiring surgical hematoma evacuation is urgently needed.

Article Synopsis
  • Childhood adversity (CA) is linked to higher risks of negative health outcomes, with differences in how various types of adversity affect brain structure during development.
  • Recent research indicates that deprivation leads to slower decreases in cortical surface area in certain brain regions, while threat exposure results in increased surface area in areas related to socio-emotional processing as adolescents age.
  • These findings suggest a need to reconsider how different forms of adversity affect brain development over time, highlighting the varying impacts on cognitive and emotional functions.

Remnant cholecystitis is a rare complication following subtotal cholecystectomy (STC), particularly when the reconstituting technique is used, which leaves a portion of the gallbladder behind. This remnant can become inflamed due to recurrent or retained gallstones. We present the case of a 39-year-old female who required a completion cholecystectomy 11 years after her initial STC due to severe recurrent right upper quadrant (RUQ) pain, nausea, and vomiting with an ultrasound that revealed cholelithiasis.

Much of the research on the effects of syndemics on HIV outcomes has utilized an additive approach. However, interaction effects may better account for syndemic synergy than an additive approach, but it remains difficult to specify interaction effects without empirical guidance. We sought to systematically compare additive and interaction effects approaches to modeling the effects of syndemic problems on antiretroviral therapy (ART) using empirically specified interaction terms.
