Project description:Goodman and Gilman's The Pharmacological Basis of Therapeutics (GGPBT) has been a cornerstone in the education of pharmacists, physicians, and pharmacologists for decades. The objectives of this study were to describe and evaluate the 13th edition of GGPBT on bases including: (1) author characteristics; (2) recency of citations; (3) conflict of interest (CoI) disclosure; (4) expert evaluation of chapters. Contributors' (N = 115) sex, professional degrees, and presence of undisclosed potential CoI-as reported by the Center for Medicare and Medicaid's Open Payments (2013-2017)-were examined. The year of publication of citations was extracted relative to Katzung's Basic and Clinical Pharmacology (KatBCP), and DiPiro's Pharmacotherapy: A Pathophysiologic Approach (DiPPAPA). Content experts provided thorough chapter reviews. The percent of GGPBT contributors that were female (20.9%) was equivalent to those in KatBCP (17.0%). Citations in GGPBT (11.5 ± 0.2 years) were significantly older than those in KatBCP (10.4 ± 0.2) and DiPPAPA (9.1 ± 0.1, p < 0.0001). Contributors to GGPBT received USD 3 million in undisclosed remuneration (Maximum author = USD 743,718). In contrast, DiPPAPA made CoI information available. Reviewers noted several strengths but also some areas for improvement. GGPBT will continue to be an important component of the biomedical curriculum. Areas of improvement include a more diverse authorship, improved conflict of interest transparency, and a greater inclusion of more recent citations.

Project description:For decades, researchers have debated the relative merits of different measures of people's ability to discriminate the correctness of their own responses (resolution). The probabilistic approach, primarily led by Nelson, has advocated the Goodman-Kruskal gamma coefficient, an ordinal measure of association. The signal detection approach has advocated parametric measures of distance between the evidence distributions or the area under the receiver operating characteristic (ROC) curve. Here we provide mathematical proof that the indices associated with the two approaches are far more similar than has previously been thought: The true value of gamma is equal to twice the true area under the ROC curve minus one. Using this insight, we report 36 simulations involving 3,600,000 virtual participants that pitted gamma estimated with the original concordance/discordance formula against gamma estimated via ROC curves and the trapezoidal rule. In all but five of our simulations-which systematically varied resolution, the number of points on the metacognitive scale, and response bias-the ROC-based gamma estimate deviated less from the true value of gamma than did the traditional estimate. Consequently, we recommend using ROC curves to estimate gamma in the future.

Project description:PurposeCurrently, patient-reported outcome measures (PROMs) are the standard instruments used to compare arthroplasty results. Goodman et al. recently published a well-constructed scale with excellent psychometric properties that can be quickly administered. The main objective of our study was to translate, culturally adapt, and validate a Spanish version of the Goodman questionnaire in patients who underwent total hip arthroplasty (THA).MethodsThe original Goodman scale was translated into Spanish and cross-culturally adapted. Then, the data from this version were tested for psychometric quality. We designed a cross-sectional study for data collection. This study enrolled 2 institutions. Patients who underwent hip replacement due to primary osteoarthritis secondary to dysplasia between 1 January 2018 and 31 December 2019 were included. A total of 153 patients were contacted twice to record the Goodman and Oxford hip scales (OHS) to assess the validity of the questionnaire. Reliability was tested using the Cronbach's alpha, Concordance using 3 test: intraclass correlation coefficient (ICC), Lin's concordance correlation coefficient (CCC), and the Bradley-Blackwood F test. The spearman correlation was used to asses correlation between the OHS and the Spanish-adapted Goodman scale.ResultsThe overall satisfaction after THA was reported to be "very satisfied" by 137 patients (75%), and only 14 patients reported some degree of dissatisfaction (6%). The improvement in quality of life was reported to be "more than I ever dreamed possible" by 41% patients. Cronbach's alpha was acceptable, reaching a coefficient of 0.95 (95% confidence interval, 0.82-1). No statistical difference (t test, p = 0.55) was found in the original version, with great internal validity. Test re-test concordance was optimal among the 3 tests used. A moderate correlation was found between the OHS and the Spanish-adapted Goodman scale.ConclusionThe Spanish version of the Goodman questionnaire in THA is a reliable, consistent, and feasible scale to evaluate patient satisfaction and improvement in the quality of life in Spanish speakers.

Project description:Patient satisfaction after total joint arthroplasties (TJA) represents a key element for the evaluation of surgery success in relation to subjects' needs and expectations. The assessment tools are applied inconsistently throughout the literature, and thus, it is difficult to compare results among different studies. Goodman et al. proposed a standardized questionnaire with strong psychometric properties for the assessment of satisfaction. The present study aims to translate, adapt, and validate the Goodman questionnaire for the Italian population. After translation and back translation, the questionnaire was administrated to 50 patients. Internal consistency, test-retest reliability, floor and ceiling effects, and construct validity were evaluated (correlation with KOOS/HOOS, SF-12 PCS/MCS, EQ-5D). Responsiveness was evaluated with respect to SF-12 PCS improvements. The Italian version of the Goodman score questionnaire demonstrated psychometric properties similar to those of the original version. The translated questionnaire showed good internal consistency (Cronbach's alpha = 0.836) and test-retest reliability (ICC: 0.507). Moderate/strong correlations were observed between the Italian version of the Goodman score and other scores. The score significantly discriminated patients who improved from those who did not improve in SF-12 PCS after treatment. This study provides an adapted and validated Italian version of the Goodman score questionnaire, with psychometric properties similar to those of its original counterpart.

Project description:AU565 cells were grown in media with DMSO as a control in 8 well MEMA for 72h and then fixed using 2% paraformaldehyde. Cells were stained with DAPI (nuclei), KRT5(Basal lineage), KRT19 (luminal lineage) and EdU (S phase activity). The cells were imaged on a Nikon HCA microscopy system, segmented with Cell Profiler, normalized using RUV and lowess using the spatial residuals as controls, and analyzed to identify microenvironment conditions that altered phenotypes of interest.
