OBJECTIVES: Just-in-time training (JITT) is a method of simulation-based training where the training occurs within the clinical environment in a concise manner. Just-in-time training has shown effects at the learner, patient, and system-wide levels. We evaluated a JITT curriculum for the procedures of intraosseous (IO) needle placement and defibrillator use in a pediatric emergency department (ED) by comparing the trainees' comfort level in performing those procedures independently (Kirkpatrick level 2a) and trainees' knowledge of the procedures/equipment (Kirkpatrick level 2b) before and after the JITT...

Searching for information is critical in many situations. In medicine, for instance, careful choice of a diagnostic test can help narrow down the range of plausible diseases that the patient might have. In a probabilistic framework, test selection is often modeled by assuming that people's goal is to reduce uncertainty about possible states of the world. In cognitive science, psychology, and medical decision making, Shannon entropy is the most prominent and most widely used model to formalize probabilistic uncertainty and the reduction thereof...

The rapid spread of the Zika virus and its association with the abnormal brain development constitute a global health emergency. With a continuing spread of the mosquito vector, the exposure is expected to accelerate in the coming years. Despite number of efforts, there is still no proper vaccine or medicine to combat this virus. Of note, the NS2B-NS3 protein is proven to be the potential target for the Zika virus therapeutics. Hence, e-pharmacophore-based drug design strategy was employed to identify potent inhibitors of NS2B-NS3 protein from ASINEX database consisting of 467,802 molecules...

In recent years, there has been an increasing focus on the need to integrate formal knowledge with clinical experience in the pre-clinical years since the initial years of medical education play an important role in shaping the attitudes of medical students towards medicine and support the development of clinical reasoning. In this study, we describe approaches that involve real patients and patient-simulation-based methodologies to teach gastroenterology to second year medical students. Our goals were to (i) demonstrate bio-psychosocial aspects of clinical practice, (ii) demonstrate commonality of gastrointestinal ailments, and (iii) help understand complex gastroenterology concepts...

INTRODUCTION: Cricothyrotomy may be necessary for airway management when a patient's airway cannot be maintained through standard techniques such as oral airway placement, blind insertion airway device, or endotracheal intubation. Wire-guided cricothyrotomy is one of many techniques used to perform a cricothyrotomy. Although there is some controversy over which cricothyrotomy technique is superior, there is no published data regarding long term retention rates. The purpose of this study is to determine whether ground based paramedics can be taught and are able to retain the skills necessary to successfully perform a wire-guided cricothyrotomy...

With the advent of personalized medicine, clinical trials studying treatment effects in subpopulations are receiving increasing attention. The objectives of such studies are, besides demonstrating a treatment effect in the overall population, to identify subpopulations, based on biomarkers, where the treatment has a beneficial effect. Continuous biomarkers are often dichotomized using a threshold to define two subpopulations with low and high biomarker levels. If there is insufficient information on the dependence structure of the outcome on the biomarker, several thresholds may be investigated...

Building on the work of Schwartz et al, Joint Bayesian analysis of birthweight and censored gestational age using finite mixture models in Statistics in Medicine, we propose a Bayesian finite mixture of bivariate regression model for causal mediation analyses. Using an identifiability condition within each component of the mixture, we express the natural direct and indirect effects of the exposure on the outcome as functions of the component-specific regression coefficients. On the basis of simulated data, we examine the behavior of the model for estimating these effects in situations where the associations between exposure, mediator, and outcome are confounded or not...

Indirubin, a bis-indole alkaloid used in traditional Chinese medicine has shown remarkable anticancer activity against chronic myelocytic leukemia. The present work was aimed to decipher the underlying molecular mechanisms responsible for its anticancer attributes. Our findings suggest that indirubin inhibited the proliferation of HeLa cells with an IC50 of 40 μM and induced a mitotic block. At concentrations higher than its IC50 , indirubin exerted a moderate depolymerizing effect on the interphase microtubular network and spindle microtubules in HeLa cells...

The ability to precisely visualize the atomic geometry of the interactions between a drug and its protein target in structural models is critical in predicting the correct modifications in previously identified inhibitors to create more effective next generation drugs. It is currently common practice among medicinal chemists while attempting the above to access the information contained in three-dimensional structures by using two-dimensional projections, which can preclude disclosure of useful features. A more accessible and intuitive visualization of the three-dimensional configuration of the atomic geometry in the models can be achieved through the implementation of immersive virtual reality (VR)...

Diabetic foot ulcers are systemic diseases that affect all blood vessels within the human body. From major blood vessels to microvasculature, hardening, thickening, and narrowing of blood vessels ultimately results to diminished blood flow to end organs. The detrimental effects of peripheral vascular disease are well recognized across medicine, particularly with regards to diabetic foot ulcers. Diabetic foot ulcers (DFU) are common across all fields of medicine, including but not limited to: orthopedics, vascular surgery, podiatry, general internal medicine, and infectious disease...
