Standardizing Assessment Of Clinical Performance In Physical Therapy: From Good Intentions To Shared Standards, Arvie Vitente, Carmina Rafael, Rolando Lazaro

Rehabilitation Sciences Department Faculty Articles

Clinical education is the crucible in which physical therapy students integrate knowledge, skills, and professional judgment into safe, ethical, and person-centered practice. Yet globally, the assessment of clinical performance remains highly variable, shaped by disparate tools, rubrics, and levels of assessor preparation. While several countries have adopted nationally standardized approaches to clinical assessment, many contexts—including the Philippines—continue to rely on locally developed or institution-specific systems, resulting in inconsistent expectations, inequitable student experiences, and limited capacity for benchmarking, research, and quality improvement. This editorial argues that good intentions alone are insufficient and that the profession must move toward shared, trustworthy standards …

Distinct Populations Of Lung Capillary Endothelial Cells And Their Functional Significance, Joel James, Dan Yi, Zhiyu Dai, Et Al.

2020-Current year OA Pubs

The role of the lung's microcirculation and capillary endothelial cells in normal physiology and the pathobiology of pulmonary diseases is obviously vital. The recent discovery of molecularly distinct aerocytes and general capillary (gCaps) endothelial cells by single-cell transcriptomics (scRNAseq) advanced the field in understanding microcirculatory milieu and cellular communications. However, increasing evidence from different groups indicated the possibility of a more heterogeneous nature of lung capillaries. Therefore, we investigated enriched lung endothelial cells by scRNAseq and identified five novel populations of gCaps with distinct molecular signatures and roles. Our analysis suggests that two major populations of gCaps that express Scn7a(Na

Cortezzo, Katharine Press Callahan, Bimal P. Chaudhari, Elliott M. Weiss, Monica Hsiung Wojcik, Krishna Acharya, Amy B. Schlegel, Kevin M. Sullivan, Jessica T. Fry

Department of Pediatrics Faculty Papers

Each year, many neonates are born with genetic diagnoses that carry a range of prognoses. As the types and availability of genetic testing have expanded, neonatal intensive care units (NICUs) have served as "launching points" for their clinical application. Broad genetic testing has both improved diagnostic precision and expanded uncertainty. Genetic information may be explicitly uncertain, as in the case of a variant of unknown significance (VUS). But it is also frequently uncertain whether/how the information relates to a patient's phenotype or what it may mean for a child's future. Even without ambiguity in the diagnosis or prognosis, the significance …
