The development and clinical implementation of personalized medicine crucially depends on the availability of high-quality human biosamples; animal models, although capable of modeling complex human diseases, cannot reflect the large variation in the human genome, epigenome, transcriptome, proteome, and metabolome. Although the biosamples available from public biobanks that store human tissues and cells may represent the large human diversity for most diseases, these samples are not always sufficient for developing biomarkers for patient-tailored therapies for neuropsychiatric disorders...

Cannabis has been widely used as a medicinal agent in Eastern medicine with earliest evidence in ancient Chinese practice dating back to 2700 BC. Over time, the use of medical cannabis has been increasingly adopted by Western medicine and is thus a rapidly emerging field that all pain physicians need to be aware of. Several randomized controlled trials have shown a significant and dose-dependent relationship between neuropathic pain relief and tetrahydrocannabinol - the principal psychoactive component of cannabis...

Big data indicates the large and ever-increasing volumes of data adhere to the following 4Vs: volume (ever-increasing amount), velocity (quickly generated), variety (many different types), veracity (from trustable sources). The last decade has seen huge advances in the amount of data we routinely generate and collect in pretty much everything we do, as well as our ability to use technology to analyze and understand it. The routine operation of modern health care systems also produces an abundance of electronically stored data on an ongoing basis as a byproduct of clinical practice...

The essential benefit of the management of hypertension is derived from the blood pressure (BP) lowering per se, indicating the importance of BP throughout 24 hours. Recent guidelines stressed the importance of home BP for the diagnosis and management of hypertension. It is well-known that cardiovascular events occur more frequently in the morning BP levels have been shown to increase during the period from night to early morning. Clinical research using ambulatory BP monitoring (ABPM) or home BP monitoring has clarified that morning BP and BP surge are more closely related to the cardiovascular risk than office BP (Kario et al...

Dear Editor I read with great interest the manuscript titled "A New Panel of Blood Biomarkers for the Diagnosis of Mild Traumatic Brain Injury/Concussion in Adults" by Shan R, et al, published in the January issue of the Journal. (1) I do have some questions. The key to marker discovery studies is a precise and accurate description of how the population was identified, including controls. I have significant concerns about the control population in the manuscript. In the presentation the characteristics of the control group are unclear, described only as "not patients in the ED" and with the same exclusion criteria of the other cohorts...

INTRODUCTION: Behavioral changes often occur after moderate-to-severe traumatic brain injury (TBI) and can lead to poor health, psychosocial functioning, and quality of life. Challenges in evaluating these behaviors often result from the complexity and variability in the way they are conceptualized and defined. We propose and test a conceptual model that is specific to behavioral symptoms after TBI, to serve as a basis for better assessment and treatment. We hypothesized that clusters of individuals, with unique emotional, cognitive, and behavioral characteristics, would emerge that would illustrate this conceptual model...

BACKGROUND: Currently, people live longer but often with poor quality of life. The decrease in healthy life-years is partly attributable to the institution of polypharmacy to treat various comorbidities. OBJECTIVES: The objectives of the study were to determine the prevalence and nature of drug-related problems (DRPs) in polypharmacy elderly patients residing in nursing homes and to test the acceptability of a pharmacist's intervention. METHODS: An exposure cohort was constituted in three Portuguese nursing homes, where all polypharmacy (five or more medicines) elderly patients (≥65 years of age) were analysed and then a random stratified sample was extracted to be subject to an intervention...

: Over the last decade, genome-wide association studies (GWAS) have generated vast amounts of analysis results, requiring development of novel tools for data visualization. Quantile-quantile (QQ) plots and Manhattan plots are classical tools which have been utilized to visually summarize GWAS results and identify genetic variants significantly associated with traits of interest. However, static visualizations are limiting in the information that can be shown. Here we present ASSOCPLOTS: , a python package for viewing and exploring GWAS results not only using classic static Manhattan and QQ plots, but also through a dynamic extension which allows to interactively visualize the relationships between GWAS results from multiple cohorts or studies...
