IntroductionOur study set out to identify the benefits for veterinary workers of structured daily well-being practices on compassion satisfaction, burnout, and secondary traumatic stress. Suggested origins of high rates of psychological stress and burnout are significant occupational concerns for veterinary workers. Many professional helpers experience an extreme state of tension and preoccupation from exposure to the suffering of those being helped. Veterinary workers are further impacted by negative associations and moral distress experienced due to limitations in the provision of quality medical care for veterinary patients. These negative experiences exist despite veterinary professionals’ work being worthwhile and highly valued.MethodsA randomized controlled study was performed over 6 months. Volunteer participants were members of a team of veterinary workers at a 24-h emergency and specialty hospital. Study participants were asked to incorporate daily well-being practice(s) into existing routines whereas control participants were not. Measures of well-being and the negative impacts of serving as veterinary helpers were assessed by having participants complete the Professional Quality of Life (ProQOL) self-assessment at baseline and at 1, 3 and 6 months. Composite scores for compassion satisfaction, burnout and secondary traumatic stress were calculated.ResultsBaseline ProQOL scores were similar between study participants and controls. Baseline compassion satisfaction (CS), burnout scores (BS), and secondary traumatic stress (STS) scores for those instituting well-being practices were 37.6 (+/− 3.6), 26 (+/− 5.3), and 26.6 (+/− 5.2). Study participants had higher compassion satisfaction scores at 6 months with mean CS scores (n = 15) of 40.1 (+/− 6.8) and adjusted scores that were on average 3.0 (95% CI 0–6.1) higher than the control group (p = 0.048). Significant differences in BS or STS scores were not seen.DiscussionImprovements were seen in CS but not BO/STS for those caregivers who implemented well-being practices into their daily routines. Factors that likely contributed to successful implementation of well-being practices include educational resources, supportive leadership, accessibility, and consistent acknowledgement and positive rewards. Proposed supportive elements and resources for maintenance of well-being practices within a team of veterinary workers include provision of a psychologically safe community and team support (including formal or informal “buddy systems”).

The chemical shift difference, Δσ, between the methylene and hydroxyl protons in the high resolution 1H nuclear magnetic resonance spectrum of ethylene glycol is shown to be pressure dependent. The equilibrium Δσ values for ethylene glycol are reported as a function of temperature and pressure between ambient conditions, 323 K and 2 kbar, respectively. This surface is used along with Δσ values measured in response to a rapid pressure increase to calculate a temperature rise that is used to infer a temperature change for water that is consistent with theoretical estimates. This work implies that compression heating and decompression cooling are not significant enough to interfere with pressure induced protein folding studies. [ABSTRACT FROM AUTHOR]

Purpose: Quantitative computed tomography (QCT)‐derived measures of lung density are valued methods for objectively characterizing lung parenchymal and peripheral airways disease and are being used in a growing number of lung disease focused trials. Detector and reconstruction improvements in CT technology have allowed for significant radiation dose reduction in image acquisition with comparable qualitative image quality. We report the impact of detector type and reconstruction type on QCT lung density measures in relation to decreasing dose indices. Methods: Two sets of studies were completed in an in vivo pig model with a SOMATOM Definition Flash CT system: (a) prior to system upgrade with conventional detectors (UFC) and filtered back projection (FBP), and (b) post system upgrade with integrated electronic detectors (STELLAR) and iterative reconstruction (SAFIRE). CT data were acquired across estimated CT volume dose indices (CTDIvol) ranging from 0.75 to 15 mGy at both inspiratory and expiratory breath holds. Semiautomated lung segmentations allowed calculation of histogram median, kurtosis, and 15th percentile. Percentage of voxels below −910 HU and −950 HU (inspiratory), and −856 HU (expiratory) were also examined. The changes in these QCT metrics from dose reduction (15 mGy down to 0.75 mGy) were calculated relative to paired reference values (15 mGy). Results were compared based on detector and reconstruction type. Results: In this study, STELLAR detectors improved concordance with 15 mGy values down to 3 mGy for inspiratory scans and 6 mGy for expiratory scans. The addition of SAFIRE reconstruction in all acquired measurements resulted in minimal deviation from reference values at 0.75 mGy. Conclusion: The use of STELLAR integrated electronic detectors and SAFIRE iterative reconstruction may allow for comparable lung density measures with CT dose indices down to 0.75 mGy.

To explore their hypothetical responses to management of fever or nasal congestion in their children, 109 parents were interviewed in a clinic waiting-room area. Most parents said they would medicate their children in these situations without first consulting a health professional. Parents were more willing to administer a drug product for fever than for nasal congestion, especially to children under 2 years of age. Although most parents selected appropriate medications for these situations, many were poorly informed about these drugs and falsely attributed germicidal and decongestant properties to aspirin and Tylenol®. Younger, less educated, indigent parents in lower-status occupations were the least well informed. Pediatricians heed to prepare parents for their role as health care providers. [ABSTRACT FROM AUTHOR]
