Article Synopsis
  • Peptide and proteins are promising biomaterials for therapeutic use, with copine 7 (CPNE7) identified as a key protein that promotes hard tissue regeneration but faces limitations due to its large size and short half-life.
  • Researchers developed six synthetic peptides derived from CPNE7 (CDP1-CDP6) and found that CDP4 demonstrated the best cell penetration and osteogenic activity in dental pulp stem cells (DPSCs), enhancing the expression of important osteogenesis-related genes.
  • When combined with injectable collagen gel, CDP4 significantly improved bone formation in a mouse model, suggesting its potential as an effective biomaterial for bone tissue engineering comparable to CPNE7 and BMP-2.

Purpose: To examine how qualitative narrative comments and quantitative ratings from end-of-rotation assessments change for a cohort of residents from entry to graduation, and explore associations between comments and ratings.

Method: The authors obtained end-of-rotation quantitative ratings and narrative comments for 1 cohort of internal medicine residents at the University of Illinois at Chicago College of Medicine from July 2013-June 2016. They inductively identified themes in comments, coded orientation (praising/critical) and relevance (specificity and actionability) of feedback, examined associations between codes and ratings, and evaluated changes in themes and ratings across years.

The purpose of this study was to evaluate the clinical impacts of ampicillin-susceptible but penicillin-resistant (ASPR) phenotypes of on clinical outcomes in patients with bloodstream infection (BSI). A total of 295 patients with an BSI from six sentinel hospitals during a 2-year period (from May 2016 to April 2018) were enrolled in this study. Putative risk factors, including host-, treatment-, and pathogen-related variables, were assessed to determine the associations with the 30-day mortality rate of patients with an BSI.

Background: Mitogen-activated protein kinases (MEK 1/2) are central components of the RAS signalling pathway and are attractive targets for cancer therapy. These agents continue to be investigated in KRAS mutant colon cancer but are met with significant resistance. Clinical investigations have demonstrated that these strategies are not well tolerated by patients.

Objective: To assess the readiness of entering residents for clinical responsibilities, the American College of Surgeons (ACS) Division of Education developed the "Entering Resident Readiness Assessment" (ACS-ERRA) Program.

Summary Background: ACS-ERRA is an online formative assessment that uses a key features approach to measure clinical decision-making skills and focuses on cases encountered at the beginning of residency. Results can be used to develop learning plans to address areas that may need reinforcement.

Background: Effective communication has been linked to a reduction in adverse events and improved patient compliance. Currently in Otolaryngology - Head and Neck Surgery (OTL-HNS) residency programs, there is limited explicit teaching of communication skills. Our objective was to implement an educational program on communication skills for residents using multisource assessment in several simulation-based contexts throughout residency.

The purpose of this study is to determine the correlation between use of antimicrobials, such as fluoroquinolone, cefoxitin, and cefotaxime, and Escherichia coli resistance using a nationwide database. Nationwide data on antimicrobial consumption for 12 years (2002 to 2013) were acquired from a database of subjects (n = 1,025,340) included in the National Health Insurance Service-National Sample Cohort. National antimicrobial resistance rates of E.

Background: To prevent the problems of traditional clinical evaluation, the "Objective Structured Clinical Examination (OSCE)" was presented by Harden as a more valid and reliable assessment instrument. However, an essential condition to guarantee a high-quality and effective OSCE is the assurance of evidence to support the validity of its scores. This study examines the psychometric properties of OSCE scores, with an emphasis on consequential and internal structure validity evidence.

Context: Medical school admissions committees use a variety of criteria to determine which candidates to admit to their programmes. Effective communication is increasingly considered a key requisite to the practice of effective medicine. Medical students with pre-medical backgrounds in the humanities and social sciences may be more likely to acquire skills relevant to patient-centred communication, either prior to or during medical school.

Purpose: Competence decisions in health professions education require combining scores from multiple sources and identifying pass-fail decisions based on noncompensatory (required to pass all subcomponents) and compensatory scoring decisions. This study investigates consequences of combining scores, reliability, and implications for validity using a national examination with subcomponent assessments.

Method: National data were used from three years (2015, 2016, and 2017) of the Japan Primary Care Association Board Certification Examination, with four subcomponent assessments: Clinical Skills Assessment-Integrated Clinical Encounter (CSA-ICE), CSA-Communication and Interpersonal Skills (CSA-CIS), Multiple-Choice Questions (MCQ), and Portfolio.

Background: Nontechnical skills are important for safe and efficient surgery. Teams performing video-assisted thoracoscopic surgery (VATS) lobectomy express that it is of utmost importance to have a shared mental model (SMM) of the patient, current situation, and team resources. However, these SMMs have never been explored in a clinical setting.

Background: The elevated preoperative ratio of early transmitral flow velocity to early diastolic velocity of the mitral annulus (E/e') as an echocardiographic index of left ventricular filling pressure is known to be associated with poor postoperative outcomes. We investigated the association between preoperative and postoperative E/e' elevation and clinical outcomes after cardiac operations.

Methods: The study divided 1,353 patients who underwent cardiac operations into four groups: preoperative and postoperative E/e' ≤15 (low-low), preoperative E/e' ≤15 but postoperative E/e' >15 (low-high), preoperative E/e' >15 but postoperative E/e' ≤15 (high-low), and preoperative and postoperative E/e' >15 (high-high).
