Are There Enough Experienced Physicians to Treat Patients Hospitalized With COVID?

In this national study of 438,895 physicians, 45% provided care to hospitalized patients and 7% provided critical care. At the high estimate of patients requiring hospitalization at the projected peak of the pandemic, 18 states and Washington, DC would have patient to physician ratios greater than 15:1 (a level associated with poor outcomes among hospitalized patients). There was considerable geographic variation in the availability of physicians: 41% of hospital service areas did not have a physician with critical care experience

Physicians and Advanced Practitioners Specializing in Nursing Home Care, 2012-2015

The number of clinicians specializing in nursing home care increased by 33.7% from 2012 to 2015, although nursing home specialists made up only 21% of nursing home clinicians in 2015. Most of these specialists were advanced practitioners (physician assistants and nurse practitioners) delivering post-acute care. The change in number of nursing home specialists varied significantly by geographic region

Assessing First Visits By Physicians To Medicare Patients Discharged To Skilled Nursing Facilities

In this study of postacute care, more than 10% of Medicare skilled nursing facility (SNF) stays included no visit from a physician or advanced practitioner. Of stays with visits, about half of initial assessments occurred within a day of admission, and nearly 80% occurred within four days. Patients who did not receive a visit from a physician or advanced practitioner were nearly twice as likely to be readmitted to a hospital (28%) or to die (14%) within 30 days of SNF admission than patients who had an initial visit

BRST approach to Lagrangian formulation of bosonic totally antisymmeric tensor fields in curved space

We apply the BRST approach, previously developed for higher spin field theories, to gauge invariant Lagrangian construction for antisymmetric massive and massless bosonic fields in arbitrary d-dimensional curved space. The obtained theories are reducible gauge models both in massless and massive cases and the order of reducibility grows with the value of the rank of the antisymmetric field. In both the cases the Lagrangians contain the sets of auxiliary fields and possess more rich gauge symmetry in comparison with standard Lagrangian formulation for the antisymmetric fields. This serves additional demonstration of universality of the BRST approach for Lagrangian constructions in various field models.Comment: 12 page

Facebook Addiction, Game online, Physical Health Among Indonesian Students

This study is essential for students to know about Facebook addiction, Game online, and physical health. The study aims to describe the level of Facebook addiction, play online, and physical health and examine their relationship. The total sample was 206 people selected using the purposive sampling method. The research design was correlational; two hundred-six participants joined this study. Each participant filled out all of the questionnaires (demographic data, the Bergen Facebook Addiction (BFAS), Game Addiction (GAS), and Physical Questionnaire (PHQ). All questionnaires were taken from the previous research and validated; the reliability test was high. Based on the Pearson correlation tests, relationships were shown between Facebook addiction, games online, and physical health. There is a significant positive correlation between Facebook addiction and physical health and games online and physical health. Facebook addiction has a positive impact on physical health. Facebook addiction will impact a student's physical health. This study findings that Facebook addiction is low level, game online moderate level, and moderate level of physical fitness. The best way to prevent students from Facebook addiction is to make them busy with school activities. Games online also have a positive impact on physical health. The longer we play the Game online, the more physical health problems we will have. Say no to Facebook addiction and games online

Impact of the Chemical Analogues of Decarboxylated Ornithine and S-Adenosylmethionine on the Rate of the L-Cells Growth in the Tissue Culture

ABSTRACT The impact of the aliphatic amino-and oxy derivatives decarboxylated ornithine and Sadenosylmethionine on the rate of the L-cells growth in a tissue culture has been investigated. The known specific inhibitors of the polyamine synthesis enzymes (DFMO and MGBG) were used for control and comparison of efficacy of the substances tested. The nature of action of 1-aminooxy-3-aminopropane (APA) and S-(5-deoxyadenosile)-S-methyl--thioethylhydroxylamine (АМА) used separately or combined one with another was similar to the effect of DFMO and MGBG though less expressed. The degree of inhibition of the Lcells growth as of the 4 th day made 50-60%. By the 7 th day the tendency to not only stabilization of the growth rate but also to the recovery thereof manifested itself. This points to the reversible nature of action of the APA and AMA combinations and constitutes the difference from the effect DFMO and MGBG

Queer In AI: A Case Study in Community-Led Participatory AI

Queerness and queer people face an uncertain future in the face of ever more widely deployed and invasive artificial intelligence (AI). These technologies have caused numerous harms to queer people, including privacy violations, censoring and downranking queer content, exposing queer people and spaces to harassment by making them hypervisible, deadnaming and outing queer people. More broadly, they have violated core tenets of queerness by classifying and controlling queer identities. In response to this, the queer community in AI has organized Queer in AI, a global, decentralized, volunteer-run grassroots organization that employs intersectional and community-led participatory design to build an inclusive and equitable AI future. In this paper, we present Queer in AI as a case study for community-led participatory design in AI. We examine how participatory design and intersectional tenets started and shaped this community’s programs over the years. We discuss different challenges that emerged in the process, look at ways this organization has fallen short of operationalizing participatory and intersectional principles, and then assess the organization’s impact. Queer in AI provides important lessons and insights for practitioners and theorists of participatory methods broadly through its rejection of hierarchy in favor of decentralization, success at building aid and programs by and for the queer community, and effort to change actors and institutions outside of the queer community. Finally, we theorize how communities like Queer in AI contribute to the participatory design in AI more broadly by fostering cultures of participation in AI, welcoming and empowering marginalized participants, critiquing poor or exploitative participatory practices, and bringing participation to institutions outside of individual research projects. Queer in AI’s work serves as a case study of grassroots activism and participatory methods within AI, demonstrating the potential of community-led participatory methods and intersectional praxis, while also providing challenges, case studies, and nuanced insights to researchers developing and using participatory methods

Gauge invariant Lagrangian construction for massive higher spin fermionic fields

We formulate a general gauge invariant Lagrangian construction describing the dynamics of massive higher spin fermionic fields in arbitrary dimensions. Treating the conditions determining the irreducible representations of Poincare group with given spin as the operator constraints in auxiliary Fock space, we built the BRST charge for the model under consideration and find the gauge invariant equations of motion in terms of vectors and operators in the Fock space. It is shown that like in massless case hep-th/0410215, the massive fermionic higher spin field models are the reducible gauge theories and the order of reducibility grows with the value of spin. In compare with all previous approaches, no off-shell constraints on the fields and the gauge parameters are imposed from the very beginning, all correct constraints emerge automatically as the consequences of the equations of motion. As an example, we derive a gauge invariant Lagrangian for massive spin 3/2 field

Association Between 5-Star Nursing Home Report Card Ratings and Potentially Preventable Hospitalizations

Nursing homes’ publicly reported star ratings increased substantially since Centers for Medicare & Medicaid Services’s Nursing Home Compare adopted a 5-star rating system. Our objective was to test whether the improvements in nursing home 5-star ratings were correlated with reductions in rates of hospitalization. We hypothesized that increased attention to 5-star star ratings motivated nursing homes to make changes that improved their star ratings but did not affect their hospitalization rate, resulting in a weakened association between ratings and hospitalizations. We used 2007-2010 Medicare hospital claims and nursing home clinical assessment data to compare the correlation between nursing home 5-star ratings and hospitalization rates before versus after 5-star ratings were publicly released. The correlation between the rate of hospitalization and a nursing home’s 5-star rating weakened slightly after the ratings became publicly available. This decrease in correlation was concentrated among patients receiving post-acute care, who experienced relatively more hospitalizations from best-rated nursing homes. The improvements in nursing home star ratings after the release of Medicare’s 5-star rating system were not accompanied by improvements in a broader measure of outcomes for post-acute care patients. Although this dissociation may be due to better matching of sicker patients to higher-quality nursing homes or superficial improvements by nursing homes to increase their ratings without substantial investments in quality improvement, the 5-star ratings nonetheless became less meaningful as an indicator of nursing home quality for post-acute care patients
