To explore the relationship between mindfulness, self-compassion and psychological flexibility, and the burnout subtypes in university students of the Psychology and Nursing degrees, and to analyse possible risk factors for developing burnout among socio-demographic and studies-related characteristics.

Cross-sectional study conducted on a sample of 644 undergraduate students of Nursing and Psychology from two Spanish universities.

The study was conducted between December 2015 and May 2016. read more Bivariate Pearson's correlations were computed to analyse the association between mindfulness facets, self-compassion and psychological flexibility, and levels of burnout. Multivariate linear regression models and bivariate and multivariate binary logistic regressions were also computed.

The three subtypes of burnout presented significant correlations with psychological flexibility, self-compassion and some mindfulness facets. Psychological flexibility, self-compassion and the mindfulness facets of observing and actprotective role of some psychological variables mindfulness, self-compassion and psychological flexibility. These should be considered as potentially protective skills for developing burnout, and therefore, undergraduate students could be trained on these abilities to face their studies and their future profession to prevent experiencing burnout syndrome.
The US opioid epidemic has prompted dramatic changes in public attitudes and regulations governing opioid prescribing. Little is known about the experiences of patients with advanced cancer using opioids in the context of the epidemic.

Semistructured interviews of 26 patients with advanced cancer were conducted between May 2019 and April 2020; their experiences self-managing chronic pain with opioids were evaluated.

Patients consistently described the negative impact of the opioid epidemic on their ability to self-manage pain. Negative media coverage and personal experiences with the epidemic promoted stigma, fear, and guilt surrounding opioid use. As a result, many patients delayed initiating opioids and often viewed their decision to take opioids as a moral failure-as "caving in." Patients frequently managed this internal conflict through opioid-restricting behaviors (eg, skipping or taking lower doses). Stigma also impeded patient-clinician communication; patients often avoided discussing opioids or gma and the logistical complications they experienced with pharmacies and insurance coverage. Many were afraid to share their concerns about opioids with their providers. .
Patients with advanced cancer suffer from significant pain and frequently receive opioids to manage their pain. Of the 26 patients with advanced cancer interviewed, the majority of patients experienced stigma about their opioid use for cancer pain management. All patients felt that the opioid epidemic fostered this stigma. Several struggled to use opioids for pain because of this stigma and the logistical complications they experienced with pharmacies and insurance coverage. Many were afraid to share their concerns about opioids with their providers. .With limited information known about the zoo-housed Sichuan takin (Budorcas taxicolor tibetana), there is a need to gain more knowledge about their basic physiology to be able to better assess their well-being. Our goal was to develop noninvasive methods to evaluate stress physiology in the Sichuan takins housed under human care. The objectives were (1) validate the use of fecal glucocorticoid metabolite (FGM) analysis to monitor adrenocortical activity and (2) determine the relationship between FGM concentrations and changes in various factors including environmental conditions, reproductive hormones, and social factors. Three (one male and two females) adult Sichuan takins were included in the study from Lincoln Park Zoo. A cortisol enzyme immunoassay was used to analyze FGM from samples that were collected 2-4 times per week. FGM was biochemically validated in the laboratory and biologically validated using pregnancy and parturition. Results showed that 1 day after birth one female had a more than a six-fold increase in FGM. A positive relationship (p  less then  .05) was observed between FGM and temperature for two of the three takins. Finally, FGM values tended to increase during times when aggression (p = .09) and reproductive (p = .08) behaviors were observed. In conclusion, environmental, reproductive, and behavioral factors could affect adrenocortical activity in zoo-housed Sichuan takins; therefore, these methods can be used to assist in the management and conservation of this threatened species both in zoos and potentially in the wild.
To derive the mass density (ρ) from dual-energy computed tomography (DECT) data by calibrating electron density (ρ
) and effective atomic numbers (Z
) of human tissues.

We propose the DEEDZ-MD method, in which a single polynomial parameterization covers the entire human-tissue range to establish an empirical quadratic relation between the atomic number-to-mass ratio and Z
. Then, we numerically evaluate the DEEDZ-MD method in reference human tissues listed in the ICRP Publication 110 and ICRU Report 46. The tissues are considered to have unknown ρ values. The attenuation coefficients of these tissues are calculated using the XCOM Photon Cross Sections Database. The DEEDZ-MD method is also applied to experimental DECT data acquired from a tissue characterization phantom and an anthropomorphic phantom at 90kV and 150kV/Sn.

The numerical analysis of the DEEDZ-MD method reveals a single quadratic relation between the atomic number-to-mass ratio and Z
in a wide range of human tissues. The simulated ρ tissues.
This study compares the effectiveness of three fractionation schemes of equal fraction size, comprising five fractions of SBRT over 5days, 10days, or 15days, respectively.

This comparative study is based on two tumor-control-probability (TCP) models that take into account tumor cell re-sensitization and repopulation during treatment; the Zaider-Minerbo-Stavreva (ZMS) and the Ruggieri-Nahum (RN) models. The ZMS model is further modified to include also re-sensitization according to the β mechanism of the linear-quadratic (LQ) model of cell killing. The modified version of the ZMS model is verified through fitting to the experimental data set of Fisher and Moulder. The study applies an idea used in a plan ranking methodology developed for the case when the specific values of the model parameters are not known.

The TCPs of the compared regimens are calculated for various values of the model parameters and for two different values of the dose per fraction. The TCPs are presented as 2-D functions of two of the model parameters for each model correspondingly.
