Phenomenological Study of Urban Elementary Principals: Reading-Proficient Students with Learning Disabilities

Changes in the demands on educational leaders have necessitated shifts in the roles and responsibilities of school principals. Meeting the needs of students with disabilities is among the critical challenges that administrators face today. The purpose of this study was to examine the lived experiences of elementary school principals where students with Specific Learning Disabilities (SLD) demonstrate reading proficiency. Phenomenological research was conducted to identify the themes associated with effective school leadership, related to this specific population, students with SLD. Informal, non evaluative observations were conducted in conjunction with analysis of leadership summaries that were submitted by teachers who were nominated by the participants, to determine theme congruence. These results indicated that the lived experiences of elementary school principals are a complex blend of characteristics and practices. Seven specific themes were identified in the qualitative interviews: 1) Embedded personal and/or professional experiences; 2) Adaptability; 3) Relationship orientation and commitment to collaboration; 4) Focused responsibility and accountability; 5) Hiring and supporting teachers while maintaining a culture of high expectations; 6) Resource allocation; 7) Reflection that informs decision making. This research provided preliminary evidence to demonstrate the lived experiences of elementary school principals, with a particular focus on students with SLD, and can be used to inform and adapt current practices to address anticipated challenges in the future

A Comprehensive Summary of Services and Resources Provided by Librarians in support of CODA Accredited Predoctoral (DDS/DMD) Dental Education Programs in the United States and Canada

Objective The objective of this study is to provide a summary of library services and resources that support dental education and research. This summary will demonstrate trends in dental librarianship as well as services and resources that can be adopted to serve the needs of dental related education programs. To date, there has not been a comprehensive summary of these services. Methods An environmental scan was carried out to take inventory of services that dental librarians (1) provide. The study population consisted of librarians who work in dental libraries or college / university libraries that serve dental programs. The librarians surveyed were from institutions with a CODA accredited DMD/DDS pre-doctoral program (2). Currently, there are 76 such programs within the United States and Canada, of which 71 responded. Conclusion Our data demonstrates that the majority of dental programs have a dedicated librarian or library liaison providing clinical, educational, and research support through a variety of approaches. Increasing awareness and utilization of available services and resources within the dental community can facilitate research and complement dental education. The service models cited here can be adapted in dental related education programs across North America

Dressing-related pain in patients with chronic wounds : an international patient perspective

This cross-sectional international survey assessed patients' perceptions of their wound pain. A total of 2018 patients (57% female) from 15 different countries with a mean age of 68.6 years (SD = 15.4) participated. The wounds were categorised into ten different types with a mean wound duration of 19.6 months (SD = 51.8). For 2018 patients, 3361 dressings/compression systems were being used, with antimicrobials being reported most frequently (n = 605). Frequency of wound-related pain was reported as 32.2%, 'never' or 'rarely', 31.1%, 'quite often' and 36.6%, 'most' or 'all of the time', with venous and arterial ulcers associated with more frequent pain (P = 0.002). All patients reported that 'the wound itself' was the most painful location (n = 1840). When asked if they experienced dressing-related pain, 286 (14.7%) replied 'most of the time' and 334 (17.2%) reported pain 'all of the time'; venous, mixed and arterial ulcers were associated with more frequent pain at dressing change (P < 0.001). Eight hundred and twelve (40.2%) patients reported that it took < 1 hour for the pain to subside after a dressing change, for 449 (22.2%) it took 1-2 hours, for 192 (9.5%) it took 3-5 hours and for 154 (7.6%) patients it took more than 5 hours. Pain intensity was measured using a visual analogue scale (VAS) (0-100) giving a mean score of 44.5 (SD = 30.5, n = 1981). Of the 1141 who reported that they generally took pain relief, 21% indicated that they did not feel it was effective. Patients were asked to rate six symptoms associated with living with a chronic wound; 'pain' was given the highest mean score of 3.1 (n = 1898). In terms of different types of daily activities, 'overdoing things' was associated with the highest mean score (mean = 2.6, n = 1916). During the stages of the dressing change procedure; 'touching/handling the wound' was given the highest mean score of 2.9, followed by cleansing and dressing removal (n = 1944). One thousand four hundred and eighty-five (80.15%) patients responded that they liked to be actively involved in their dressing changes, 1141 (58.15%) responded that they were concerned about the long-term side-effects of medication, 790 (40.3%) of patient indicated that the pain at dressing change was the worst part of living with a wound. This study adds substantially to our knowledge of how patients experience wound pain and gives us the opportunity to explore cultural differences in more detail

Variants in autophagy-related genes and clinical characteristics in melanoma: a population-based study

Autophagy has been linked with melanoma risk and survival, but no polymorphisms in autophagy-related (ATG) genes have been investigated in relation to melanoma progression. We examined five single-nucleotide polymorphisms (SNPs) in three ATG genes (ATG5; ATG10; and ATG16L) with known or suspected impact on autophagic flux in an international population-based case-control study of melanoma. DNA from 911 melanoma patients was genotyped. An association was identified between (GG) (rs2241880) and earlier stage at diagnosis (OR 0.47; 95% Confidence Intervals (CI) = 0.27-0.81, P = 0.02) and a decrease in Breslow thickness (P = 0.03). The ATG16L heterozygous genotype (AG) (rs2241880) was associated with younger age at diagnosis (P = 0.02). Two SNPs in ATG5 were found to be associated with increased stage (rs2245214 CG, OR 1.47; 95% CI = 1.11-1.94, P = 0.03; rs510432 CC, OR 1.84; 95% CI = 1.12-3.02, P = 0.05). Finally, we identified inverse associations between ATG5 (GG rs2245214) and melanomas on the scalp or neck (OR 0.20, 95% CI = 0.05-0.86, P = 0.03); ATG10 (CC) (rs1864182) and brisk tumor infiltrating lymphocytes (TILs) (OR 0.42; 95% CI = 0.21-0.88, P = 0.02), and ATG5 (CC) (rs510432) with nonbrisk TILs (OR 0.55; 95% CI = 0.34-0.87, P = 0.01). Our data suggest that ATG SNPs might be differentially associated with specific host and tumor characteristics including age at diagnosis, TILs, and stage. These associations may be critical to understanding the role of autophagy in cancer, and further investigation will help characterize the contribution of these variants to melanoma progression

An integrated cell atlas of the lung in health and disease

Single-cell technologies have transformed our understanding of human tissues. Yet, studies typically capture only a limited number of donors and disagree on cell type definitions. Integrating many single-cell datasets can address these limitations of individual studies and capture the variability present in the population. Here we present the integrated Human Lung Cell Atlas (HLCA), combining 49 datasets of the human respiratory system into a single atlas spanning over 2.4 million cells from 486 individuals. The HLCA presents a consensus cell type re-annotation with matching marker genes, including annotations of rare and previously undescribed cell types. Leveraging the number and diversity of individuals in the HLCA, we identify gene modules that are associated with demographic covariates such as age, sex and body mass index, as well as gene modules changing expression along the proximal-to-distal axis of the bronchial tree. Mapping new data to the HLCA enables rapid data annotation and interpretation. Using the HLCA as a reference for the study of disease, we identify shared cell states across multiple lung diseases, including SPP1+ profibrotic monocyte-derived macrophages in COVID-19, pulmonary fibrosis and lung carcinoma. Overall, the HLCA serves as an example for the development and use of large-scale, cross-dataset organ atlases within the Human Cell Atlas
