Spinal application of ROS scavenger, Phenyl-N-tert-butylnitrone (PBN), depressed the already established spinal LTP. Spinal application of H2O2, one ROS, induced LTP and bilateral mechanical allodynia, increased the frequency and amplitude of spontaneous excitatory postsynaptic currents in laminar II neurons, and phosphorylated GluN2B and p65 in the dorsal horn. This study provided electrophysiological and behavioral evidence that NOX2-derived ROS in the spinal cord contributed to persistent mirror-image pain by enhancing the synaptic transmission, which was mediated by increasing presynaptic glutamate release and activation of NMDA receptor and NF-κB in the spinal dorsal horn.Many people believe that weather influences chronic musculoskeletal pain. Previous studies on this association are narratively reviewed, with particular focus on comparing methodologies and summarising study findings in light of study quality. We searched 5 databases (Medline, Embase, Web of Science, PsycINFO, and Scopus) for observational studies on the association between weather variables and self-reported musculoskeletal pain severity. Of 4707 located articles, 43 were eligible for inclusion. The majority (67%) found some association between pain and a weather variable. Temperature, atmospheric pressure, relative humidity, and precipitation were most often investigated. For each weather variable, some studies found an association with pain (in either direction), and others did not. Most studies (86%) had a longitudinal study design, usually collecting outcome data for less than a month, from fewer than 100 participants. Most studies blinded participants to study aims but were at a high risk of misclassification of exposure and did not meet reporting requirements. Pain severity was most often self-reported (84%) on a numeric rating scale or visual analog scale. Weather data were collected from local weather stations, usually on the assumption that participants stayed in their home city. Analysis methods, preparation of weather data, and adjustment for covariates varied widely between studies. The association between weather and pain has been difficult to characterise. To obtain more clarity, future studies should address 3 main limitations of the previous literature small sample sizes and short study durations, misclassification of exposure, and approach to statistical analysis (specifically, multiple comparisons and adjusting for covariates).OBJECTIVE The study aimed to investigate the impacts of patient safety incident (PSI) experienced by the general public. METHODS We conducted a self-administered online survey, in which we examined the following experiences of the patients and the caregivers the level of harm induced by PSIs, difficulties due to PSIs, posttraumatic stress disorder (PTSD), and posttraumatic embitterment disorder, etc. A χ test was performed to identify differences in difficulties because of the direct and indirect experience of PSIs. A 1-way analysis of variance was performed to identify the differences in the total PTSD and posttraumatic embitterment disorder scores according to the characteristics of PSIs. RESULTS Of the survey participants who indirectly experienced PSIs, 27.2% and 29.3% reported that they experienced sleep disorder and eating disorder, respectively. However, of the participants who directly experienced PSIs, 40.7% and 42.6% reported experiencing sleep disorder and eating disorder, respectively. The average PTSD scores of the participants who experienced permanent disability and death were 83.8 points for less than 6 months of elapsed time since the incident, 80.8 points for 6 months to less than 5 years, and 94.7 points for 5 years or more; they did not demonstrate a statistically significant difference (P = 0.217). CONCLUSIONS This study suggested that the general public who experienced PSIs have numerous difficulties at the time of the incident and the trauma or the resentment of the general public does not quickly regress even if time passes.OBJECTIVES Although many health care institutions believe that clinical peer review is vital for identifying and improving quality of care, peer review is perceived by many clinicians as variable and inherently punitive. Successful peer review requires institutional leadership and adoption of a just culture approach to investigating and determining accountability for medical errors that result in harm. METHODS We describe how an academic medical center implemented and adapted its clinical peer review processes to be consistent with just culture theory and provide a roadmap that other institutions may follow. Specific examples of peer review are highlighted to show how the process improved patient safety in the departments of emergency medicine, internal medicine, and pediatrics. find more RESULTS The most significant process improvement was shifting from a tradition of assigning letter grades of "A," "B," or "C" to determine whether preventable adverse events were caused by "human error," "at-risk behavior," or "reckless behavior." This categorization of human behaviors enabled patient safety officers within 3 departments to develop specific interventions to protect patients and enlist physician support for improving clinical systems. CONCLUSIONS Each department's success was due to recognition of different patient and provider cultures that offer unique challenges. The transformation of peer review was a crucial first step to shift perceptions of peer review from a punitive to a constructive process intended to improve patient safety. Our experience with reengineering clinical peer review shows the importance of focusing on just culture as a key method to prevent patient harm.OBJECTIVES The aims of the study were to examine the reactions of first-year health profession students to medical errors and determine whether differences exist between disciplines. METHODS After viewing the Team STEPPS Program's Susan Sheridan video that describes two separate medical errors, students from anesthesia assistant, medical imaging, medicine, nursing, physical therapy, and physician assistant programs provided unstructured open responses reflecting on initial impressions of medical errors depicted in the film. Student responses were assessed via inductive coding techniques and thematic analysis and stratified by discipline. Frequencies of key themes were calculated. Descriptive analyses characterized respondents and χ tests compared responses between disciplines. RESULTS In a review of 373 student responses (80% response rate), 255 students expressed an emotion-based reply, of which 93.75 were negative with such comments as they felt horrified, appalled, and disappointed by the patient's experience.
