Tauopathies are a group of neurodegenerative diseases defined by abnormal aggregates of tau, a microtubule-associated protein encoded by MAPT. MAPT expression is near absent in neural progenitor cells (NPCs) and increases during differentiation. This temporally dynamic expression pattern suggests that MAPT expression could be controlled by transcription factors and cis-regulatory elements specific to differentiated cell types.

Sphingolipid metabolism is dysregulated in many cancers, allowing cells to evade apoptosis through increased sphingosine-1-phosphate (S1P) and decreased ceramides. Ceramidases hydrolyze ceramides to sphingosine, which is phosphorylated by sphingosine kinases to generate S1P. The S1P allows cells to evade apoptosis by shifting the equilibrium away from ceramides, which favor cell death.

Background: Opioid use has come under increasing scrutiny, driven in part by the opioid crisis and growing concerns that up to 6% of opioid-naïve patients may become chronic opioid users. This has resulted in a revaluation of perioperative practice. For this reason, we implemented a multidisciplinary pathway to reduce perioperative opioid usage through education and standardization of practice.

Background: Primary healthcare (PHC) integration has been promoted globally as a tool for health sector reform and universal health coverage (UHC), especially in low-resource settings. However, for a range of reasons, implementation and impact remain variable. PHC integration, at its simplest, can be considered a way of delivering PHC services together that sometimes have been delivered as a series of separate or 'vertical' health programmes.

The access to, use, and exchange of health information is crucial when strengthening public health services and improving access to care. However, many health system stakeholders, including community groups are perpetually excluded from accessing and using health information. This is problematic as community groups, themselves end-users of care, are well-positioned to keep the health system accountable, provide feedback on the quality of services, and identify emerging health concerns.

Purpose: Because clinical specialists often lack time and training to address secondary health issues such as smoking cessation, the National Cancer Institute Cancer Center Cessation Initiative (C3I) has mobilized cancer centers to develop systems for treating patients' tobacco dependence.

Methods: One university-based cancer center was able to develop a program that formalized smoking treatment using a collaborative, multidisciplinary care team with overlapping expertise in cancer care, medication management, and tobacco cessation. Program planners delivered tobacco cessation services in the outpatient setting by automating identification of eligible patients using a tobacco registry in the electronic health records, directly involving oncology pharmacists in medication oversight, using dedicated tobacco treatment specialists to provide cessation services, and engaging oncologists through active communications protocols.

Article Synopsis
  • Sister chromatid cohesion (SCC) is crucial for proper chromosome segregation, and the ESCO2 gene is vital for establishing SCC; alterations in ESCO2 are linked to various human cancers.
  • Research shows that reduced ESCO2 (haploinsufficiency) leads to decreased SCC and faster tumor development in specific genetic contexts, particularly in p53 heterozygous models, but not in those with full p53 mutations.
  • The study also reveals that while reduced SCC causes chromosome instability, this instability isn't the direct driver of quicker tumor onset; instead, increased mitotic recombination in ESCO2 deficient cases seems to contribute to faster cancer progression.
