Pain inhibition by opioids-new concepts.

CONCLUSION: The epidemic of opioid misuse has shown that there is a lack of fundamental knowledge about the characteristics and management of chronic pain, that conflicts of interest and validity of models must be more intensively considered in the context of drug development and that novel analgesics with less addictive potential are urgently needed. Currently, the most promising perspectives appear to be augmenting endogenous opioid actions and the selective activation of peripheral opioid receptors.

The objective of this study was to evaluate the preoperative anxiety of hospitalized patients exposed to Spiritist “passe,” laying on of hand with the intention of healing (Sham) and without laying on of hand. Other variables as depression, pain, physiological parameters, muscle tension, and well-being were assessed. Patients in the Spiritist “passe” intervention group showed greater reductions in anxiet y (p

Conclusion: In this cohort of patients with esophageal cancer admitted to intensive care units with acute illness, the in-hospital mortality rate was very high. The requirement for invasive mechanical ventilation and metastatic disease were independent prognostic factors and should be considered in discussions about the short-term outcomes of these patients.

Loss of chromosome Y (LOY) is a mosaic aneuploidy that can be detected mainly in blood samples of male individuals. Usually, LOY occurrence increases with chronological age in healthy men. Moreover, recently LOY has been reported in association with several diseases, such as cancer, where its frequency is even higher. The Y chromosome is one of the shortest chromosomes of the human karyotype, and it is crucial for correct male development. This chromosome has functions beyond the male reproductive system, and loss of its genes or even LOY can have consequences for the male body that are yet to be elucidated. Analyses of th...

This article reviews pharmacological principles and research strategies aiming at novel opioids with reduced side effects. Basic mechanisms underlying pain, opioid analgesia and other opioid actions are outlined. To illustrate the clinical situation and medical needs, plasticity of opioid receptors, intracellular signaling pathways, endogenous and exogenous opioid receptor ligands, central and peripheral sites of analgesic and side effects are discussed. Expert opinion: The epidemic of opioid misuse has taught us that there is a lack of fundamental knowledge about the characteristics and management of chronic pain, that co...

  RX PAD With the death of the entertainer Prince attributed to a fentanyl overdose, and new FDA warnings, opioids have been making headlines. Since the most common reason patients visit the emergency department is for pain, it is not surprising that emergency physicians prescribe and administer medications such as oxycodone on a daily basis. Here are some of the basics about how oxycodone works, and also the reason why chronic users may be at even higher risk of unexpected respiratory depression. HOW IT WORKS: Oxycodone is a semi-synthetic opioid with analgesic properties. Oxycodone binds to mu, kappa, and delta opio...
