Host Long Noncoding RNAs as Key Players in Mycobacteria-Host Interactions.

Mycobacterial infections, caused by various species within the Mycobacterium genus, remain one of the main challenges to global health across the world. Understanding the complex interplay between the host and mycobacterial pathogens is essential for developing effective diagnostic and therapeutic strategies. Host long noncoding RNAs (lncRNAs) have emerged as key regulators in cellular response to bacterial infections within host cells.

5-HT1A regulates axon outgrowth in a subpopulation of Drosophila serotonergic neurons.

Serotonergic neurons produce extensively branched axons that fill most of the central nervous system, where they modulate a wide variety of behaviors. Many behavioral disorders have been correlated with defective serotonergic axon morphologies. Proper behavioral output therefore depends on the precise outgrowth and targeting of serotonergic axons during development.

Containing SARS-CoV-2 in hospitals facing finite PPE, limited testing, and physical space variability: Navigating resource constrained enhanced traffic control bundling.

The COVID-19 outbreak has led to a focus by public health practitioners and scholars on ways to limit spread while facing unprecedented challenges and resource constraints. Recent COVID-19-specific enhanced Traffic Control Bundling (eTCB) recommendations provide a cogent framework for managing patient care pathways and reducing health care worker (HCW) and patient exposure to SARS-CoV-2. eTCB has been applied broadly and has proven to be effective in limiting fomite and droplet transmissions in hospitals and between hospitals and the surrounding community.

Insomnia and Mild Cognitive Impairment.

Insomnia is a common problem in older people, especially in patients with mild cognitive impairment (MCI) whose circadian rhythm is often compromised. Insomnia exerts such a toll on caregivers that it is frequently the primary reason for seeking to institutionalize their loved ones. Three different types of insomnia are recognized: sleep-onset or initial insomnia, sleep maintenance or middle insomnia, and early morning awakening or late insomnia.

Agnosia Interferes With Daily Hygiene in Patients With Dementia.

Patients with dementia, particularly Alzheimer's disease, may not recognize that their clothes are dirty. They may see the food stains and discoloration of the clothes and yet because of their agnosia are unable to integrate these observations and deduce that their clothes are dirty and need to be changed. They will, therefore, resist attempts to get them to change clothes, especially if these clothes happen to be their favorite ones.
