Up-regulation of transient receptor potential vanilloid subfamily, member 1 (TRPV1) is associated with the development and maintenance of cancer pain. The present study aimed to investigate the electrophysiological function of the up-regulated TRPV1 and the potential regulatory effects of insulin-like growth factor-1 (IGF-1) on TRPV1 expression in peripheral nerves in a rat model of bone cancer pain. ⋯ Our results provide novel evidence for the increase of IGF-1 in tibia bone marrow, which is responsible for the up-regulation of TRPV1 expression and function in the peripheral nerves of bone cancer pain rats.

Randomized Controlled Trial Multicenter Study Observational Study
Clinical Application of the COPD Assessment Test: Longitudinal Data from the CHAIN Cohort.
The COPD Assessment Test (CAT) has been proposed for assessing health status in COPD, but little is known about its longitudinal changes. The objective of this study was to evaluate 1-year CAT variability in patients with stable COPD and to relate its variations to changes in other disease markers. ⋯ One-year longitudinal data show variability in CAT scores among patients with stable COPD similar to mMRC scale score, which is the best predictor of 1-year CAT changes. Further longitudinal studies should confirm long-term CAT variability and its clinical applicability.

Randomized Controlled TrialA Novel Blood-Sparing Agent in Cardiac Surgery? First In-Patient Experience with the Synthetic Serine Protease Inhibitor MDCO-2010: A Phase II, Randomized, Double-Blind, Placebo-Controlled Study in Patients Undergoing Coronary Artery Bypass Grafting with Cardiopulmonary Bypass.
Antifibrinolytics have been used for 2 decades to reduce bleeding in cardiac surgery. MDCO-2010 is a novel, synthetic, serine protease inhibitor. We describe the first experience with this drug in patients. ⋯ This first-in-patient study demonstrated dosage-proportional PK for MDCO-2010 and reduction of chest tube drainage and transfusions in patients undergoing primary coronary artery bypass grafting. Antifibrinolytic and anticoagulant effects were demonstrated using various markers of coagulation. MDCO-2010 was well tolerated and showed an acceptable initial safety profile. Larger multi-institutional studies are warranted to further investigate the safety and efficacy of this compound.

Variability in labor pain has been associated with demographic, clinical, and psychological factors. Polymorphisms of the β2-adrenergic receptor gene (ADRB2) influence sensitivity to experimental pain in humans and are a risk factor for chronic pain. The authors hypothesized that polymorphisms in ADRB2 may influence labor pain. ⋯ ADRB2 genotype correlates with labor pain but explained less than 1% of the intersubject variance in the model.

Obesity is a growing health problem and associated with immune dysfunction. Sepsis is defined as systemic inflammatory response syndrome that occurs during infection. Excessive inflammation combined with immune dysfunction can lead to multiorgan damage and death. ⋯ Relative hyperleptinemia of class 1 obesity or induced by treatment is protective in sepsis. Leptin seems to play a regulatory role in the immune system in sepsis, and treatment of relative hypoleptinemia could offer a new way of an individual sepsis therapy.
