One-Year Functional Outcomes After Invasive Mechanical Ventilation for Older Adults With Preexisting Long-Term Care-Needs.
To examine 1-year functional outcomes after invasive mechanical ventilation for adults greater than or equal to 65 years with preexisting long-term care-needs. ⋯ Among patients in preexisting care-needs levels 2-5 who received invasive mechanical ventilation, 76.0-79.2% died or had worsened care-needs within 1 year. These findings may aid shared decision-making among patients, their families, and heath care professionals on the appropriateness of starting invasive mechanical ventilation for people with poor functional and cognitive status at baseline.

The loss of GABAergic inhibition is a mechanism that underlies neuropathic pain. Therefore, rescuing the GABAergic inhibitory tone through the activation of GABA A receptors is a strategy to reduce neuropathic pain. This study was designed to elucidate the function of the spinal α 6 -containing GABA A receptor in physiological conditions and neuropathic pain in female and male rats. ⋯ Finally, α 6 subunit is expressed in humans. This receptor is found in CGRP + and P2X3 + primary afferent fibers but not astrocytes in the human spinal dorsal horn. Our results suggest that the spinal α 6 -containing GABA A receptor has a sex-specific antinociceptive role in neuropathic pain, suggesting that this receptor may represent an interesting target to develop a novel treatment for neuropathic pain.

Complex regional pain syndrome (CRPS) is characterized by inflammation and a failure of multimodal signal integration in the central nervous system (CNS). Central nervous system reorganization might account for sensory deficits, pain, and motor symptoms in CRPS, but it is not clear how motor control is affected by CNS mechanisms. The present study characterized the motor performance and related cortical activity of 16 CRPS patients and 16 control participants during the planning of visually guided unimanual grips, in patients with either the unaffected left or the affected right hand, and investigated resting-state sensorimotor coupling in MRI. ⋯ Fear of movement or individual pain scores contributed only marginally to the observed effects. The study suggests that changes in planning-related sensorimotor CNS regions may explain difficulties with force exertion and motor control in CRPS. Perspective : Functional changes in motor planning-related brain regions might indicate that feedback-enhanced functional motor training may be effective for CRPS rehabilitation.

Increasing numbers of faculty who are underrepresented in medicine has been a focus of academic health systems. Understanding the experiences of these faculty helps in creating environments that are inclusive and supportive, promoting faculty success. When compared with non-minoritized faculty, minoritized faculty face racism, isolation, diversity efforts disparities, clinical efforts disparities, lack of faculty development, and promotion disparities. ⋯ They may be excluded from conversations, group chats, get togethers, or other work-related or social functions. These feelings can manifest as imposter syndrome and impact work performance and decision-making. In this article, the author shares how to recognize and mitigate isolation to promote an inclusive environment for all faculty.

Acute heart failure (AHF) exacerbations are a leading cause of hospitalization in the United States. Despite the frequency of AHF hospitalizations, there are inadequate data or practice guidelines on how quickly diuresis should be achieved. ⋯ Aggressive net fluid targets within the first 48 h are associated with effective relief of patient self-reported dyspnea and improved long-term outcomes without adversely affecting renal function.
