Stress and Quality of Life Among Parents of Children with Congenital Heart Disease Referred for Psychological Services

Objective The study examined parent stress and health‐related quality of life (HRQOL) among families of children with congenital heart disease (CHD) referred for psychological services. Methods Parents of 54 children (85% boys) aged 3 to 13 (Mage = 7.48, SD = 2.38) completed measures to assess parenting stress (Parenting Stress Index – Short Form; Pediatric Inventory for Parents) and the PedsQL Family Impact Module. Medical information was retrieved from medical record review. Results Half of parents of children with single ventricle anatomy had clinically significant levels of parenting stress. Parents of children with single ventricle anatomy reported more frequent illness‐related stress and more difficulty dealing with illness‐related stress than parents of children with two ventricle anatomy. Younger gestational age at birth and referral for attention or behavior problems were associated with greater likelihood of parent at‐risk psychosocial functioning. Conclusions Among children referred for psychological services, many parents report significant stress and significant negative impact of the child\u27s medical condition on the family. Results underscore the need to consider assessing parent psychosocial functioning and providing additional support for parents of children with CHD

CeMnNi4: an impostor half-metal

Recent experiments show CeMnNi$_{4}$ to have a nearly integer magnetic moment and a relatively large transport spin polarization, as probed by Andreev reflection, suggesting that the material is a half metal or close to it. However, the calculations reported here show that it is not a half metal at all, but rather a semimetal of an unusual nature. Phonon properties should also be quite unusual, with rattling low-frequency Mn modes. Nontrivial transport properties, including a large thermolectric figure of merit, $ZT,$ are predicted in the ferromagnetic state of the well ordered stoichiometric CeMnNi$_{4}$Comment: 4 pages, 6 fig

The Black Hole Mass - Galaxy Luminosity Relationship for Sloan Digital Sky Survey Quasars

We investigate the relationship between the mass of the central supermassive black hole, M_bh, and the host galaxy luminosity, L_gal, in a sample of quasars from the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7). We use composite quasar spectra binned by black hole mass and redshift to assess galaxy features that would otherwise be overwhelmed by noise in individual spectra. The black hole mass is calculated using the photoionization method, and the host galaxy luminosity is inferred from the depth of the Ca II H + K features in the composite spectra. We evaluate the evolution in the M_bh - L_gal relationship by examining the redshift dependence of Delta log M_bh, the offset in black hole mass from the local black hole - bulge relationship. There is little systematic trend in Delta log M_bh out to z = 0.8. Using the width of the [O III] emission line as a proxy for the stellar velocity dispersion, sigma_*, we find agreement of our derived host luminosities with the locally-observed Faber-Jackson relation. This supports the utility of the width of the [O III] line as a proxy for sigma_* in statistical studies.Comment: 10 pages, 5 figures; final version; major revision

Accretion Disk Temperatures of QSOs: Constraints from the Emission Lines

QSO emission-line spectra are compared to predictions based on theoretical ionizing continua of accretion disks. Observed line intensities do not show the expected trend of higher ionization with higher accretion disk temperature as derived from the black hole mass and accretion rate. This suggests that, at least for accretion rates close to the Eddington limit, the inner disk does not reach temperatures as high as expected from standard disk theory. Modified radial temperature profiles, taking account of winds or advection in the inner disk, achieve better agreement with observation. This conclusion agrees with an earlier study of QSO continuum colors as a function of disk temperature. The emission lines of radio-detected and radio-undetected sources show different trends as a function of disk temperature.Comment: 9 pages, 8 figures, submitted to Ap

Preserving the Force: A Quality Improvement Project to Reduce the Risk of Opioid Use Disorder in the Military

Military service members incur combat and noncombat related injuries which may lead to acute or chronic pain. Treatment of these conditions with opioids may place them at risk for opioid use disorder (OUD). Opioid related overdoses among the military community increased by 50% from 2010 to 2019. The Sole Provider Program (SPP) is recommended to address the risks of OUD among Veterans receiving care at military installations. The goal of this evidence-based project was to ensure that all persons who receive opioid prescriptions at a military facility were evaluated for inclusion into a SPP and prescribed naloxone. Objectives included: 1) Develop policy to outline the SPP program and staff/provider roles. 2) Use the Analyze Prescription Monitoring Program Utilizer Report to identify patients who meet SPP criteria. 3) Develop educational materials and educate clinic staff and providers on the SPP. 4) Educate patients on SPP, pain management and naloxone use. The Plan Do Study Act model was used to implement the evidence-based quality improvement project. Project outcomes are as follows: 1) SPP policy approved at all levels. 2) 43 patients alerted as high risk for OUD, 11 recommended for SPP, 19 required naloxone prescriptions. 3) Patient educational materials developed and approved. 4) 45% of providers trained, education adopted and uploaded to virtual platform for mandatory completion. Advanced Practice Registered Nurses manage and prescribe opioids in the military setting and should play a key role in development and implementation of the SPP

The Black Hole Mass - Galaxy Bulge Relationship for QSOs in the SDSS DR3

We investigate the relationship between black hole mass and host galaxy velocity dispersion for QSOs in Data Release 3 of the Sloan Digital Sky Survey. We derive black hole mass from the broad Hbeta line width and continuum luminosity, and the bulge stellar velocity dispersion from the [OIII] narrow line width. At higher redshifts, we use MgII and [OII] in place of Hbeta and [OIII]. For redshifts z < 0.5, our results agree with the black hole mass - bulge velocity dispersion relationship for nearby galaxies. For 0.5 < z < 1.2, this relationship appears to show evolution with redshift in the sense that the bulges are too small for their black holes. However, we find that part of this apparent trend can be attributed to observational biases, including a Malmquist bias involving the QSO luminosity. Accounting for these biases, we find ~0.2 dex evolution in the black hole mass-bulge velocity dispersion relationship between now and redshift z ~ 1.Comment: Accepted by ApJ, 15 pages, 9 figure

Wheelchair-based game design for older adults

Few leisure activities are accessible to institutionalized older adults using wheelchairs; in consequence, they experience lower levels of perceived health than able-bodied peers. Video games have been shown to be an engaging leisure activity for older adults. In our work, we address the design of wheelchair-accessible motion-based games. We present KINECTWheels, a toolkit designed to integrate wheelchair movements into motion-based games, and Cupcake Heaven, a wheelchair-based video game designed for older adults using wheelchairs. Results of two studies show that KINECTWheels can be applied to make motion-based games wheelchair-accessible, and that wheelchair-based games engage older adults. Through the application of the wheelchair as an enabling technology in play, our work has the potential of encouraging older adults to develop a positive relationship with their wheelchair.
