ReviewPharmacological and clinical differences among transmucosal fentanyl formulations for the treatment of breakthrough cancer pain. A review article.
Breakthrough pain (BTP) is highly prevalent (59.2%) in chronic cancer patients and normally needs rescue treatments' with opioids when pain flares up. Transmucosal oral/nasal fentanyl formulations are commonly used in clinical practice. The different methods of release influence the pharmacokinetics and clinical properties of these formulations. ⋯ In parallel, we report the differences in delivery systems, bioavailability, maximum plasma concentration (Cmax), plasma half-life, and time to reach Cmax (tmax). Considerable variability emerged between formulations. This suggests some considerations on the choice of the fentanyl formulation in the light of the BTP features in each clinical case.

Basic Critical Care Echocardiography by Pulmonary Fellows: Learning Trajectory and Prognostic Impact Using a Minimally Resourced Training Model.
The spread of basic critical care echocardiography may be limited by training resources. Another barrier is the lack of information about the learning trajectory and prognostic impact of individual basic critical care echocardiography domains like acute cor pulmonale determination and left ventricular function estimation. We thus developed a minimally resourced training model and studied the latter outcomes. ⋯ Basic critical care echocardiography training using minimal resources is feasible. New trainees can achieve reasonable competency in most basic critical care echocardiography domains after performing about 30 examinations within the first year. The relatively high prevalence of abnormalities and the significant association of acute cor pulmonale with ICU mortality support the need for basic critical care echocardiography training.

Paediatric chronic pain patients are a heterogeneous group. Individuals respond differently to standardized treatment. ⋯ The patient subgroups that were established proved stable across samples. Depending on the subgroup classification, patients differed in changes of core outcomes. These results offer initial hints for the need for subgroup-specific treatment planning.

The Antihypersensitive and Anti-inflammatory Activities of a Benzofuranone Derivative in Different Experimental Models in Mice: The Importance of the Protein Kinase C Pathway.
Benzofuranone (BF1) was synthesized and its effects evaluated on mechanical hypersensitivity and paw edema models induced by different agents and on neuropathic pain induced by partial ligation of the sciatic nerve. An attempt was also made to elucidate the mechanism of action. ⋯ BF1 has dose-dependent antihypersensitive and antiinflammatory effects in both acute and chronic models of pain and inflammation, possibly mediated through interference with the PKC activation pathway. The easy and fast synthesis of this compound, low-cost, low-concentration-requirement, and once-daily-administration drug suggest it as a candidate for future clinical studies.

Lamiophlomis rotata is an orally available Tibetan herb prescribed for the management of pain, with shanzhiside methylester (SM) and 8-O-acetyl-SM as quality control ingredients. This study aimed to evaluate the antinociceptive properties of L. rotata, determine whether SM and 8-O-acetyl-SM are principle effective ingredients, and explore whether L. rotata produces antinociception through activation of spinal glucagon-like peptide-1 receptors (GLP-1Rs). ⋯ Results support the notion that the activation of spinal GLP-1Rs leads to specific antinociception in pain hypersensitivity and further suggest that GLP-1R is a human-validated target molecule for the treatment of chronic pain.
