A Transcendental Phenomenological Study Exploring How Licensed Marriage and Family Therapists Describe the Emotional Impact of the COVID-19 Pandemic

The purpose of this qualitative, phenomenological study was to describe the experiences of Licensed Marriage and Family Therapists (LMFT) in private practice during the COVID-19 pandemic. The study was viewed through the lens of resilience theory, which suggests that an individual\u27s ability to adapt and overcome adverse experiences is based on their individual level of resilience. Eight LMFTs varying in demographics, such as age, gender, and ethnicity, as well as length of time in practice participated in individual interviews exploring their lived experiences during the pandemic. The study\u27s questions aimed to gain a better understanding of the emotional impact of the pandemic, how the therapists described the emotional impact on their personal and professional lives, and how they described the feelings associated with stress. Themes that emerged based on participants\u27 lived experiences included recognition of the need for a healthy work/life balance as well the recognition of feelings of fear, anger, and uncertainty during the pandemic

Quality of Life for old patients with dementia in nursing homes

Hensikten med oppgaven var å belyse ulike miljøtiltak og aktiviteter som sykepleieren kan iverksette, for å fremme trivsel og livskvalitet til pasienter med aldersdemens på sykehjem. Oppgavebesvarelsen er en litteraturstudie som bygger på faglitteratur og 14 vitenskapelige forskningsartikler. Da de utvalgte artiklene ble analysert, ble det gjort en tekstanalyse inspirert av en innholdsanalyse. Resultatet viser hjemlig atmosfære som tiltak for å fremme trivsel og livskvalitet, sansehage som tiltak for å fremme trivsel og livskvalitet og aktivitet som tiltak for å fremme trivsel og livskvalitet. Ut i fra resultatet er det grunn til å tro at sykepleieres bidrag i forhold til organisering og tilrettelegging av pasientenes fysiske inne og utemiljø er sentrale for å kunne fremme trivsel og livskvalitet til pasienter med aldersdemens

B Lymphocytes Are Required during the Early Priming of CD4\u3csup\u3e+\u3c/sup\u3e T Cells for Clearance of \u3cem\u3ePneumocystis\u3c/em\u3e Infection in Mice

B cells play a critical role in the clearance of Pneumocystis. In addition to production of Pneumocystis-specific Abs, B cells are required during the priming phase for CD4+ T cells to expand normally and generate memory. Clearance of Pneumocystis was found to be dependent on Ag specific B cells and on the ability of B cells to secrete Pneumocystis-specific Ab, as mice with B cells defective in these functions or with a restricted BCR were unable to control Pneumocystis infection. Because Pneumocystis-specific antiserum was only able to partially protect B cell–deficient mice from infection, we hypothesized that optimal T cell priming requires fully functional B cells. Using adoptive transfer and B cell depletion strategies, we determined that optimal priming of CD4+ T cells requires B cells during the first 2–3 d of infection and that this was independent of the production of Ab. T cells that were removed from Pneumocystis-infected mice during the priming phase were fully functional and able to clear Pneumocystis infection upon adoptive transfer into Rag1−/− hosts, but this effect was ablated in mice that lacked fully functional B cells. Our results indicate that T cell priming requires a complete environment of Ag presentation and activation signals to become fully functional in this model of Pneumocystis infection

Characterization of HIV-Specific CD4+T Cell Responses against Peptides Selected with Broad Population and Pathogen Coverage

CD4+ T cells orchestrate immunity against viral infections, but their importance in HIV infection remains controversial. Nevertheless, comprehensive studies have associated increase in breadth and functional characteristics of HIV-specific CD4+ T cells with decreased viral load. A major challenge for the identification of HIV-specific CD4+ T cells targeting broadly reactive epitopes in populations with diverse ethnic background stems from the vast genomic variation of HIV and the diversity of the host cellular immune system. Here, we describe a novel epitope selection strategy, PopCover, that aims to resolve this challenge, and identify a set of potential HLA class II-restricted HIV epitopes that in concert will provide optimal viral and host coverage. Using this selection strategy, we identified 64 putative epitopes (peptides) located in the Gag, Nef, Env, Pol and Tat protein regions of HIV. In total, 73% of the predicted peptides were found to induce HIV-specific CD4+ T cell responses. The Gag and Nef peptides induced most responses. The vast majority of the peptides (93%) had predicted restriction to the patient’s HLA alleles. Interestingly, the viral load in viremic patients was inversely correlated to the number of targeted Gag peptides. In addition, the predicted Gag peptides were found to induce broader polyfunctional CD4+ T cell responses compared to the commonly used Gag-p55 peptide pool. These results demonstrate the power of the PopCover method for the identification of broadly recognized HLA class II-restricted epitopes. All together, selection strategies, such as PopCover, might with success be used for the evaluation of antigen-specific CD4+ T cell responses and design of future vaccines

Rubin Observatory LSST Transients and Variable Stars Roadmap

The Vera C. Rubin Legacy Survey of Space and Time holds the potential to revolutionize time domain astrophysics, reaching completely unexplored areas of the Universe and mapping variability time scales from minutes to a decade. To prepare to maximize the potential of the Rubin LSST data for the exploration of the transient and variable Universe, one of the four pillars of Rubin LSST science, the Transient and Variable Stars Science Collaboration, one of the eight Rubin LSST Science Collaborations, has identified research areas of interest and requirements, and paths to enable them. While our roadmap is ever-evolving, this document represents a snapshot of our plans and preparatory work in the final years and months leading up to the survey\u27s first light

Factors associated with Anaplasma spp. seroprevalence among dogs in the United States

Background Dogs in the United States are hosts to a diverse range of ticks and tick-borne pathogens, including A. phagocytophilum, an important emerging canine and human pathogen. Previously, a Companion Animal Parasite Council (CAPC)-sponsored workshop proposed factors purported to be associated with the infection risk for tick-transmitted pathogens in dogs in the United States, including climate conditions, socioeconomic characteristics, local topography, and vector distribution. Methods Approximately four million test results from routine veterinary diagnostic tests from 2011–2013, which were collected on a county level across the contiguous United States, are statistically analyzed with the proposed factors via logistic regression and generalized estimating equations. Spatial prevalence maps of baseline Anaplasma spp. prevalence are constructed from Kriging and head-banging smoothing methods. Results All of the examined factors, with the exception of surface water coverage, were significantly associated with Anaplasma spp. prevalence. Overall, Anaplasma spp. prevalence increases with increasing precipitation and forestation coverage and decreases with increasing temperature, population density, relative humidity, and elevation. Interestingly, socioeconomic status and deer/vehicle collisions were positively and negatively correlated with canine Anaplasma seroprevalence, respectively. A spatial map of the canine Anaplasma hazard is an auxiliary product of the analysis. Anaplasma spp. prevalence is highest in New England and the Upper Midwest. Conclusions The results from the two posited statistical models (one that contains an endemic areas assumption and one that does not) are in general agreement, with the major difference being that the endemic areas model estimates a larger prevalence in Western Texas, New Mexico, and Colorado. As A. phagocytophilum is zoonotic, the results of this analysis could also help predict areas of high risk for human exposure to this pathogen

Medicare Expenditures and Healthcare Utilization in a Multi-ethnic Community-based Population with Dementia from Incidence to Death

Introduction: While individuals live with dementia for many years, utilization and expenditures from disease onset through the end-of-life period have not been examined in ethnically diverse samples. Methods: We used a multiethnic, population-based, prospective study of cognitive aging (Washington Heights-Inwood Columbia Aging Project) linked to Medicare claims to examine total Medicare expenditures and health care utilization among individuals with clinically diagnosed incident dementia from disease onset to death. Results: High-intensity treatment (hospitalizations, life-sustaining procedures) was common and mean Medicare expenditures per year after diagnosis was $69,000. Non-Hispanic blacks exhibited higher spending relative to Hispanics and non-Hispanic whites 1 year after diagnosis. Non-Hispanic blacks had higher total (mean=$205,000) Medicare expenditures from diagnosis to death compared with non-Hispanic whites (mean=$118,000). Hispanics’ total expenditures and utilization after diagnosis was similar to non-Hispanic whites despite living longer with dementia. Discussion: Health care spending for patients with dementia after diagnosis through the end-of-life is high and varies by ethnicity

Understanding the utility of “Talk-to-Me” an online suicide prevention program for Australian university students

Background: Australian university students are at risk of experiencing poor mental health, being vulnerable to self-harm and suicidal ideation. Aim: “Talk-to-Me” is a suicide ideation prevention Massive open online course (MOOC) previously showing it can support Western Australian university students' knowledge of identifying and responding to suicide ideation in themselves and others. Methods: A multi-site one-group pre-test/post-test design with a 12-week follow-up explored the efficacy of “Talk-to-Me” for university students Australia-wide, evaluating the influence of COVID-19 and location. Overall, 217 students (55% female; mage = 24.93 years [18, 60]) enrolled in this study from 2020 to 2021. Participants' responses to suicidal statements, mental health literacy, generalized self-efficacy, help-seeking behavior, and overall utility of the program were collected at baseline, post-MOOC (10 weeks from baseline) and 12-week follow-up. The effect of time and location interaction was explored using a random-effects regression model. Results: Findings indicated significant improvement in participants' knowledge of positive mental health support strategies (ES = 0.42, p &lt; 0.001) and recognizing appropriate responses to suicidal statements (ES = 0.37, p &lt; 0.001) at 10-weeks, with further improvement at 12 weeks follow-up (ES = 0.47 and 0.46, p &lt; 0.001). Students reported higher generalized self-efficacy at the 12-week follow-up compared to baseline (ES = 0.19, p = 0.03) and an increased tendency to seek professional help for mental health issues (ES = 0.22, p = 0.02). Conclusion: These findings provide preliminary evidence of the efficacy of the “Talk-to-Me” program in supporting ‎university students across Australia to increase their suicide-related knowledge and skills, ‎general self-efficacy, and overall mental fitness.</p
