BACKGROUND Overprescribing of opioid pain relievers (OPR) can result in multiple adverse health outcomes, including fatal overdoses. Interstate variation in rates of prescribing OPR and other prescription drugs prone to abuse, such as benzodiazepines, might indicate areas where prescribing patterns need further evaluation. METHODS CDC analyzed a commercial database (IMS Health) to assess the ...
BACKGROUND In health, organizational participatory research (OPR) refers to health organization members participating in research decisions, with university researchers, throughout a study. This non-academic partner contribution to the research may take the form of consultation or co-construction. A drawback of OPR is that it requires more time from all those involved, compared to non-participa...
The role of pathological response in long-term outcome is still unclear in cervical cancer patients treated with neoadjuvant chemotherapy (NACT) in China. This study aimed to investigate the effect of optimal pathologic response (OPR) on survival in the patients treated with NACT and radical hysterectomy. First, 853 patients with stage IB2-IIB cervical cancer were included in a retrospective an...
The experience of pain in humans is modulated by endogenous opioids, but it is largely unknown how the opioid system adapts to chronic pain states. Animal models of chronic pain point to upregulation of opioid receptors (OpR) in the brain, with unknown functional significance. We sought evidence for a similar relationship between chronic pain and OpR availability in humans. Using positron emiss...
BACKGROUND Overdose deaths involving opioid pain relievers (OPR), also known as opioid analgesics, have increased and now exceed deaths involving heroin and cocaine combined. This report describes the use and abuse of OPR by state. METHODS CDC analyzed rates of fatal OPR overdoses, nonmedical use, sales, and treatment admissions. RESULTS In 2008, drug overdoses in the United States caused 3...
Delta- and kappa-opioid receptors (OPRs), but not micro-OPRs, are expressed in the myenteric plexus of the porcine distal small intestine. In a subpopulation of myenteric neurons, delta- and kappa-OPRs seem to be colocalized and may functionally interact. In this study, radioligand binding was used to characterize myenteric OPR populations in detail. The nonselective OPR antagonist [3H]diprenor...
Here we report a novel murine zinc-finger gene, Opr, belonging to the opa/Zic family. Opr is expressed in the entire embryonic ectoderm before gastrulation, but gradually restricted to the anterior part from the mid to late streak stage. At the beginning of neural induction, Opr is expressed throughout the anterior neural plate, but is soon restricted to the neural ridge. After neural tube clos...
Open peer review (OPR) is a cornerstone of the emergent Open Science agenda. Yet to date no large-scale survey of attitudes towards OPR amongst academic editors, authors, reviewers and publishers has been undertaken. This paper presents the findings of an online survey, conducted for the OpenAIRE2020 project during September and October 2016, that sought to bridge this information gap in order ...
To evaluate the effect of outpatient pulmonary rehabilitation (OPR) on dyspnea, we measured this symptom using a visual analogue scale during graded treadmill exercise testing and with baseline and transitional dyspnea indices (TDI). The latter measure overall dyspnea in three spheres: functional impairment, magnitude of task, and magnitude of effort. Twenty patients with COPD referred for OPR ...
Prescription opioid pain reliever (OPR) misuse and diversion is an important and growing public health problem in the United States that is responsible for significant morbidity and mortality. Emergency physicians are among the top prescribers of OPRs, yet the relative contribution of emergency department (ED) OPR prescriptions to the overall opioid abuse epidemic remains unclear. This study cr...
