Alcohol Withdrawal Assessment Tool (AWAT) Reliability and Validity: Implications for Nurses Caring for Inpatients With Mental Health Disorders.

Background: Alcohol use affects 14.5 million Americans and high prevalence of use and potential for withdrawal among hospitalized patients presents a challenge for health care professionals to anticipate and manage effectively. Due to the acuity and fast-paced nature of the hospital environment, nurses need assessment tools that can be readily completed and drive efficient protocol-based treatment.

Pressure Injury Prevention and Wound Management for the Patient Who Is Actively Dying: Evidence-Based Recommendations to Guide Care.

Preventing pressure injuries and wound deterioration can be challenging for the patient at the end of life. Pressure injuries are often deemed unavoidable when a patient is actively dying; however, the time frame for this process is variable. As the skin fails in an actively dying patient, interventions should align with the patient and family's goals.

Active vacuolar H+ ATPase and functional cycle of Rab5 are required for the vacuolation defect triggered by PtdIns(3,5)P2 loss under PIKfyve or Vps34 deficiency.

The two evolutionarily conserved mammalian lipid kinases Vps34 and PIKfyve are involved in an important physiological relationship, whereby the former produces phosphatidylinositol (PtdIns) 3P that is used as a substrate for PtdIns(3,5)P2 synthesis by the latter. Reduced production of PtdIns(3,5)P2 in proliferating mammalian cells is phenotypically manifested by the formation of multiple translucent cytoplasmic vacuoles, readily rescued upon exogenous delivery of PtdIns(3,5)P2 or overproduction of PIKfyve. Although the aberrant vacuolation phenomenon has been frequently used as a sensitive functional measure of localized PtdIns(3,5)P2 reduction, cellular factors governing the appearance of cytoplasmic vacuoles under PtdIns3P-PtdIns(3,5)P2 loss remain elusive.

The Protein Complex of Neurodegeneration-related Phosphoinositide Phosphatase Sac3 and ArPIKfyve Binds the Lewy Body-associated Synphilin-1, Preventing Its Aggregation.

The 5-phosphoinositide phosphatase Sac3, in which loss-of-function mutations are linked to neurodegenerative disorders, forms a stable cytosolic complex with the scaffolding protein ArPIKfyve. The ArPIKfyve-Sac3 heterodimer interacts with the phosphoinositide 5-kinase PIKfyve in a ubiquitous ternary complex that couples PtdIns(3,5)P2 synthesis with turnover at endosomal membranes, thereby regulating the housekeeping endocytic transport in eukaryotes. Neuron-specific associations of the ArPIKfyve-Sac3 heterodimer, which may shed light on the neuropathological mechanisms triggered by Sac3 dysfunction, are unknown.
