Radon (222Rn) is a radioactive gas emanating from geological materials. Inhalation of this gas is closely related to an increase in the probability of lung cancer if the levels are high. The usual methodology for the quantification of radon by passive methods is the use of etched solid-state nuclear track detectors, frequently in combination with optical microscopes or image scanning for image acquisition and software-based image processing for track counting. Currently available commercial instrumentation, as the Radosys microscopy system, is quite expensive, so the development of alternative methodologies is desirable. In this work, a simple, fast and low-cost image acquisition system for the determination of tracks in chemically etched CR-39 solid-state nuclear track detectors to quantify 222Rn alpha tracks has been proposed. The image of the detector surface is obtained by a conventional light stereoscopic microscope, transmitted by a CCD camera into the computer, and analyzed by the ImageJ open-source software. This methodology was employed to analyze 45 samples collected in dwellings and caves located in the region of Extremadura (Southwest Spain). Results show a good correlation coefficient of r2 = 0.98 between the reference and purposed methodology and excellent repeatability, demonstrating that the system enables routine counting tracks for radon measurement as an alternative to the Radosys microscopy instrument.We present experimental and MCNP modeled results of neutron flux monitoring in an irradiator, which consists of a252Cf sealed source housed in the center of a cubic block of high-density polyethylene. This work is contributing to our development in the delayed gamma-ray spectroscopy non-destructive assay technique for nuclear safeguards and security applications. We evaluated the thermal and resonance flux values using the Westcott foil activation method for two measurement position count rates of 197Au and 115In. Comparisons between the calculated thermal fluxes from measurements and those from MCNP models show deviations of ~20%. However, both the measured and modeled thermal fluxes are two orders of magnitude higher than the fluxes at the resonance peak energies at both measurement positions, demonstrating that the irradiator is sufficient. Furthermore, this work showed that with a252Cf sealed source of a strength of 4.4 × 106 n.s-1, a thermal flux in the range 2-5 × 104 n.s-1.cm-2 is achievable in our compact irradiator making it suitable for active analysis techniques such as DGS.The health congruence paradox can have important implications for those working with older adults as older adults' health understanding may be vague or directed toward health concerns other than those medically identified. Objective health was measured as diagnosed conditions from medical records. Two measures of subjective health were obtained through relational visits of university students, 1) health concerns older adults reported on a visit survey, 2) health concerns students reported during casual conversation. The results showed that community dwelling older adults with lower cognitive functioning ability were more susceptible to the health congruence paradox on the subjective measure of the survey report. Qualitative analysis of health concerns from subjective measures found older adults most concerned about health conditions impacting daily functioning, such as mobility and cognition, but not diagnosed hypertension. This mixed methods study confirmed the importance of understanding older adults' subjective health with measures easily obtained through relational visits with university students.The purpose of this study was to address cognitive emotional factors (frustration intolerance beliefs, cognitive emotion regulation strategies) related to burnout among professionals caring for older persons. A sample of 202 nurses and care assistants for older people completed online questionnaires about their cognitive emotion regulation strategies, frustration intolerance beliefs, and burnout. Use of maladaptive strategies, especially self-blame and catastrophizing, predicted greater emotional exhaustion and depersonalization. Adaptive strategy use, such as refocusing on planning and positive reappraisal, was found to be linked to both lower emotional exhaustion and higher personal accomplishment. Frustration intolerance beliefs appeared to be closely associated with the emotional exhaustion and depersonalization dimensions of burnout, with higher frustration intolerance beliefs indicating a high risk of depersonalization. The present findings have several practical implications for reducing nurses' burnout based on cognitive behavioral therapy approaches, such as rational emotive behavior or mindfulness therapies.

Identify doctors' and nurses' perceptions of effective communication strategies when talking with family members of patients with hospital-acquired delirium.

We conducted focus groups and interviews of hospitalists, anesthesiologists, and nurses using a semi-structured approach. We rigorously analyzed transcribed data using a constant comparative method.

We conducted six focus groups and 14 interviews. Participants included 20 hospitalists, 9 anesthesiologists, and 21 nurses. Clinicians identified three communication approaches as effective when communicating with family of delirium patients Provide reassurance, educate families, and engage in family-centered communication.

In communicating with families of patients with post-operative delirium, clinicians work to reassure and educate families using family-centered communication. Different approaches are used by different types of clinicians to accomplish this goal. Temsirolimus clinical trial Clinicians recognized the importance of involving family members in the patients' recovery.

Though clinically common and familiar to clinicians, delirium may be a new diagnosis for family members and thus compassion and education are vital. Due to the different clinical roles, education may be different for each discipline.
