We report a chemical isotope labeling (CIL) liquid chromatography mass spectrometry (LC-MS) method generally applicable for tracking metabolomic changes from samples collected in an animal model for studying disease development and treatment. A rat model of surgically induced osteoarthritis (OA) was used as an example to illustrate the workflow and technical performance. Experimental duplicate analyses of 234 plasma samples were carried out using dansylation labeling LC-MS targeting the amine/phenol submetabolome...

Due to the increasing demographic changes and the fact that cardiovascular diseases are still the leading cause of death, the mean chronological age of patients undergoing cardiac surgery is steadily increasing. In 2015, 14.8% of these patients were aged 80 years and older. This meta-analysis reviewed if and under what circumstances elderly patients benefit from cardiac surgical procedures without running the risk of limitations in the quality of life and high rates of morbidity and mortality. Generally, the chronological age was not a risk factor for higher perioperative and postoperative morbidity and mortality but the biological age was the critical factor, in particular the associated comorbidities of patients and the timing of the surgical procedure in the course of the disease...

Structural models are mathematical representations of the salient aspects of a phenomenon or process. Models of even moderate complexity are "run" using computer-based numerical analysis and simulation. In medicine, such models are used for inference, prediction, or to inform clinical and policy decision-making; thus, model assessment is paramount. Areas covered: This paper provides a unifying overview of methods for model validation and calibration, and surveys studies comparing alternative validation and calibration approaches...

Organic phosphonic acids and organic phosphonic acid esters have been of much interest due to their applications in the fields of medicine, agriculture and industrial chemistry. Boronic acids can act as synthetic intermediates and building blocks and are used in sensing, protein manipulation, therapeutics, biological labelling and separation. The additional introduction of an aminophosphonic acid group into a boronic acid may give new opportunities for application. To study the structure of such multifunctional compounds, we prepared two new derivatives which can be easily converted to the corresponding phosphonic acids...

Individualized treatment rules (ITRs) tailor treatments according to individual patient characteristics. They can significantly improve patient care and are thus becoming increasingly popular. The data collected during randomized clinical trials are often used to estimate the optimal ITRs. However, these trials are generally expensive to run, and, moreover, they are not designed to efficiently estimate ITRs. In this article, we propose a cost-effective estimation method from an active learning perspective. In particular, our method recruits only the "most informative" patients (in terms of learning the optimal ITRs) from an ongoing clinical trial...

INTRODUCTION: There has been renewed interest in the use of subcutaneous testosterone pellets for the treatment of hypogonadism since the introduction of Testopel in 2008 by Slate Pharmaceuticals (Durham, NC, USA). Manufacturer guidelines recommend using two to six pellets; however, in the clinical setting, this is deemed insufficient. This has produced a wide variety of testosterone pellet usage that is not fully understood. AIM: To better understand subcutaneous testosterone pellet implantation practices among members of the Sexual Medicine Society of North America (SMSNA)...

This study evaluates the implementation of clinical references in undergraduate medical education. For this purpose, images of typical diagnostic, intraoperative and clinical findings were integrated into two different teaching formats and adapted to the learning objectives of the Institute of Anatomy in Leipzig. Paper based questionnaires were used to evaluate the status quo (without clinical images) and the optimal time of implementation, as well as the benefit for the students of human medicine. Three test groups were drawn from two preclinical semesters (2014 and 2015)...

Operation Canine Lifeline was a tabletop exercise developed by students and faculty of Boston University School of Medicine's Healthcare Emergency Management master's program. The tabletop exercise led to discussion on current protocols for canines working in the field, what occurs if a canine encounters a toxin in the field, and what to do in situations of national security that require working with civilian agencies. This discussion led to the creation of a set of recommendations around providing prehospital veterinary care to government working dogs...
