More opioids, more pain: Fueling the fire
For more than a century, clinicians have noticed a paradoxical phenomenon: certain patients who are taking opioids (which are supposed to numb pain) become more sensitive to pain than those who are not taking opioids. The earliest observation of this phenomenon can be traced back to the British physician Sir Clifford Allbutt, who, in 1870, described it: “at such times I have certainly felt it a great responsibility to say that pain, which I know is an evil, is less injurious than morphia, which may be an evil. Does morphia tend to encourage the very pain it pretends to relieve?” Research studies and clinical observations over the years have identified the phenomenon Dr. Allbutt noticed as opioid-induced hyperalgesia (OIH). What is opioid-induced hyperalgesia? Hyperalgesia is an increased pain response from a stimulus (cause) that usually provokes a minor pain response. For example, getting your blood drawn for lab testing usually causes mild discomfort, but this common medical procedure would be very painful for certain patients who are taking opioids chronically. OIH is a lesser known side effect of long-term opioid therapy, but a serious one, and yet another reason doctors should carefully select who may benefit from extended use of these pain medications. What causes OIH? The mechanism behind opioid-induced hyperalgesia is complex and involves molecular and chemical changes in the brain and spinal cord. Opioids tend to activate specific receptors that block pai...
In this study, we show that LOC389641 is involved in PTC, which suggests that it may be a target for TC therapies. PMID: 32940082 [PubMed - in process]
Conclusion: STAT6 may act as a prognostic biomarker and provide useful information for immunotherapy in thyroid carcinoma. PMID: 32940081 [PubMed - in process]
Authors: Moll SA, Wiertz IA, Vorselaars AD, Zanen P, Ruven HJ, van Moorsel CH, Grutters JC Abstract Aim: Cancer antigen 15-3 (CA 15-3) is a baseline biomarker in idiopathic pulmonary fibrosis (IPF), but its value during follow-up is unknown. Materials and methods: Associations between serum CA 15-3 and pulmonary function tests during 1-year follow-up were evaluated by a mixed model in 132 IPF treated with pirfenidone or nintedanib. Results: Increased baseline (median: 56 kU/l) and follow-up CA 15-3 levels were inversely associated with forced vital capacity and diffusing capacity of the lung for carbon monoxid...
Biomarkers for immune checkpoint inhibitors in non-small-cell lung cancer. Biomark Med. 2020 Jul;14(11):929-932 Authors: Fuschillo S, Battiloro C, Rocco D, D Gravara L, Motta A, Maniscalco M PMID: 32940076 [PubMed - in process]
Conclusion: Metabolite biomarker candidates for PC are useful for detecting high-risk IPMN, which can progress to PC. PMID: 32940075 [PubMed - in process]
Conclusion: This study indicated that approximately a third of the CRC patients are diagnosed with EMAST, hereupon EMAST as a prognostic and predictive biomarker should be more studied clinically. PMID: 32940074 [PubMed - in process]
This article aims to review current advances in revealing relationship between tumors and abnormal N-glycosylation and discuss leading-edge applications of N-glycosylation in developing novel tumor biomarkers. PMID: 32940073 [PubMed - in process]
CONCLUSIONS: The F-V relationship assessed during both specific (SSKT) and nonspecific upper-body tasks (bench press and bench pull) may distinguish between kayakers specialized in different distances. PMID: 32942255 [PubMed - as supplied by publisher]
Authors: van Campen C(MC, Rowe PC, Verheugt FWA, Visser FC Abstract OBJECTIVES: Muscle pain and fibromyalgia (FM) are common among individuals with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). We recently demonstrated that during orthostatic stress testing, adults with ME/CFS reported increased pain. In the current study, we hypothesised that pain pressure thresholds (PPT) would decrease and temporal summation (windup) would increase after head-up tilt testing (HUT), and that the presence of co-morbid FM would be associated with greater change in both measures. METHODS: We studied adult ME/CFS p...
CONCLUSIONS: This study suggests that peripheral blood hsa_circ_0082688-hsa_circ_0008675 level in SLE+RI patients is upregulated and may also serve as a potential biomarker for SLE+RI patient diagnosis and treatment. PMID: 32940208 [PubMed - as supplied by publisher]
