Case ReportsChanges in Whole-Body Oxygen Consumption and Skeletal Muscle Mitochondria During Linezolid-Induced Lactic Acidosis.
To better clarify the pathogenesis of linezolid-induced lactic acidosis. ⋯ Linezolid-induced lactic acidosis is associated with diminished global oxygen consumption and extraction. These changes reflect selective inhibition of mitochondrial protein synthesis (probably translation) with secondary mitonuclear imbalance. One novel aspect of linezolid toxicity that needs to be confirmed is blunting of reactive mitochondrial biogenesis and unfolded protein response.

Pre-existing chronic pain has been associated with severe postoperative pain. To analyze the impact of chronic pain on non-surgical acute pain, a cohort of patients with acute herpes zoster was studied. ⋯ Patients with chronic pain had higher intensity of zoster-related acute pain. Furthermore, they showed more pain-related dysfunction and needed longer hospitalization than patients without chronic pain. These results go along with findings for acute postoperative pain.

Pain is multi-dimensional and may be better addressed through a holistic, biopsychosocial approach. Massage therapy is commonly practiced among patients seeking pain management; however, its efficacy is unclear. This systematic review and meta-analysis is the first to rigorously assess the quality of massage therapy research and evidence for its efficacy in treating pain, function-related and health-related quality of life outcomes across all pain populations. ⋯ Based on the evidence, massage therapy, compared to no treatment, should be strongly recommended as a pain management option. Massage therapy is weakly recommended for reducing pain, compared to other sham or active comparators, and improving mood and health-related quality of life, compared to other active comparators. Massage therapy safety, research challenges, how to address identified research gaps, and necessary next steps for implementing massage therapy as a viable pain management option are discussed.

With the advent of genome-wide association studies (GWAS) and next-generation sequencing, more than 20 risk loci that affect Alzheimer's disease have been identified. These loci are estimated to explain about 28% of the heritability of liability, 30% of familial risk, and over 50% of sibling recurrence risk of developing Alzheimer's disease. ⋯ The search for functionally relevant genetic variants in risk loci detected in GWAS has revealed that the genetic variations underlying Alzheimer's disease include common variants affecting expression and splicing, a functional intragenic copy number variation, and rare pathogenic variants in risk loci, some of which might lead to familial Alzheimer's disease. An understanding of the contribution of these variants to the development of Alzheimer's disease has several clinical implications, including enhancing diagnostic accuracy and providing targets for the development of novel treatments.

Comparative Study
A Comparative Study of Glasgow Coma Scale and Full Outline of Unresponsiveness Scores for Predicting Long-Term Outcome After Brain Injury.
The aim of this study was to compare predictive ability of hospital Glasgow Coma Scale (GCS) scores and scores obtained using a novel coma scoring tool (the Full Outline of Unresponsiveness [FOUR] scale) on long-term outcomes among patients with traumatic brain injury. Preliminary research of the FOUR scale suggests that it is comparable with GCS for predicting mortality and functional outcome at hospital discharge. No research has investigated relationships between coma scores and outcome 12 months postinjury. ⋯ GCS and FOUR scores were comparable in bivariate associations with long-term outcome. Discharge coma scores performed best for both tools, with GCS discharge scores predictive in multivariate models.
