#1
Rob M Kok, Charles F Reynolds
Importance: Depression in older adults is a common psychiatric disorder affecting their health-related quality of life. Major depression occurs in 2% of adults aged 55 years or older, and its prevalence rises with increasing age. In addition, 10% to 15% of older adults have clinically significant depressive symptoms, even in the absence of major depression. Observations: Depression presents with the same symptoms in older adults as it does in younger populations...

Next-generation sequencing prototypes for the routine diagnosis of resistance to antiretrovirals approved for the treatment of HIV infection are now being used in many clinical diagnostic laboratories. As some of the next-generation sequencing platforms may be a source of errors, it is necessary to improve the currently available protocols and implement bioinformatic tools that may help to correctly identify the presence of resistance mutations with clinical impact. Several studies have addressed these issues in recent years...

To ensure safe and effective dosing of gentamicin in children therapeutic drug monitoring (TDM) is recommended. TDM utilising Bayesian forecasting software is recommended, but is unavailable as no population model exists that describes the pharmacokinetics of gentamicin in paediatric oncology patients. This study aimed to develop and externally evaluate a population pharmacokinetic model of gentamicin to support personalised dosing in paediatric oncology patients. A non-linear mixed effect population pharmacokinetic model was developed from retrospective data...

BACKGROUND: The drug inventory in the hospital consumes a large part of the hospital's budget. Classic drug management is based on weekly visits of the pharmacist in the departments, writing an order and dispensing it. This method is wasteful in terms of sending a bulk of drugs that will not necessarily be utilized, and it is also inefficient in terms of human resources. The unit-dose method, which is more advanced, is based on filling out individual prescriptions for each of the inpatients in the department...

REVIEW
Sophie M Andrews, Sarah Rowland-Jones
The human immunodeficiency virus (HIV) evolves rapidly owing to the combined activity of error-prone reverse transcriptase, recombination, and short generation times, leading to extensive viral diversity both within and between hosts. This diversity is a major contributing factor in the failure of the immune system to eradicate the virus and has important implications for the development of suitable drugs and vaccines to combat infection. This review will discuss the recent technological advances that have shed light on HIV evolution and will summarise emerging concepts in this field...

There is a great concern nowadays regarding alcohol consumption and drug abuse, especially in young people. Analyzing the social environment where these adolescents are immersed, as well as a series of measures determining the alcohol abuse risk or personal situation and perception using a number of questionnaires like AUDIT, FAS, KIDSCREEN, and others, it is possible to gain insight into the current situation of a given individual regarding his/her consumption behavior. But this analysis, in order to be achieved, requires the use of tools that can ease the process of questionnaire creation, data gathering, curation and representation, and later analysis and visualization to the user...

BACKGROUND: Hospital acquired fungal infections are defined as "never events"-medical errors that should never have happened. Systemic Candida albicans infections results in 30-50% mortality rates. Typically, adhesion to abiotic medical devices and implants initiates such infections. Efficient adhesion initiates formation of aggressive biofilms that are difficult to treat. Therefore, inhibitors of adhesion are important for drug development and likely to have a broad spectrum efficacy against many fungal pathogens...

The alarming numbers of poorly soluble discovery compounds have centered the efforts towards finding strategies to improve the solubility. One of the attractive approaches to enhance solubility is via amorphization despite the stability issue associated with it. Although the number of amorphous-based research reports has increased tremendously after year 2000, little is known on the current research practice in designing amorphous formulation and how it has changed after the concept of solid dispersion was first introduced decades ago...

Genetic-guided nutritional supplementation therapy in personalized medicine is the type of treatment that prevents and acts against errors during the copying process of a cell's deoxyribonucleic acid (DNA), mistakes that lead to diversification in the DNA sequence at certain locations, called single nucleotide polymorphisms (SNPs). Positive results are quickly achieved using one of the four types of therapy. These types are: personalized, when individual human genetic variations drive individual treatment, preventive, with a tailored healthcare strategy and therapeutic preventive drugs and vaccines, participatory, when empowered patients make informed choices and take responsibility of their own health and predictive, using a proactive approach to health and medicine...

INTRODUCTION: Interpersonal early life trauma (I-ELT) is associated with a myriad of functional impairments in adulthood, increased risk of drug addiction, and neuropsychiatric disorders. While deficits in emotional regulation and amygdala functioning are well characterized, deficits in general cognitive functioning have also been documented. However, the neural underpinnings of cognitive dysfunction in adults with a history of I-ELT and the potential relationship between amygdala-based functional connectivity and behavioral performance are currently poorly understood...

Potential long term effects on brain development are a concern when drugs are used to treat depression and anxiety in childhood. In this study, male juvenile rhesus monkeys (three-four years of age) were dosed with fluoxetine or vehicle (N=16/group) for two years. Histomorphometric examination of cortical dendritic spines conducted after euthanasia at one year postdosing (N=8/group) suggested a trend toward greater dendritic spine synapse density in prefrontal cortex of the fluoxetine-treated monkeys. During dosing, subjects were trained for automated cognitive testing, and evaluated with a test of sustained attention...

Our increased understanding of the mechanistic heterogeneity of diseases has pushed the development of targeted therapeutics. We do not expect all patients with a given disease to benefit from a targeted drug; only those in the target population. That is, those with sufficient dysregulation in the biomolecular pathway targeted by treatment. However, due to complexity of the pathway, and/or technical issues with our characterizing assay, it is often hard to characterize the target population until well into large-scale clinical trials...

There is an increasing demand to analyze many biological samples for disease understanding and biomarker discovery. Quantitative proteomics strategies that allow simultaneous measurement of multiple samples have become widespread and greatly reduce experimental costs and times. Our laboratory developed a technique called combined precursor isotopic labeling and isobaric tagging (cPILOT), which enhances sample multiplexing of traditional isotopic labeling or isobaric tagging approaches. Global cPILOT can be applied to samples originating from cells, tissues, bodily fluids, or whole organisms and gives information on relative protein abundances across different sample conditions...

BACKGROUND: RecA is a bacterial multifunctional protein essential to genetic recombination, error-prone replicative bypass of DNA damages and regulation of SOS response. The activation of bacterial SOS response is directly related to the development of intrinsic and/or acquired resistance to antimicrobials. Although recent studies directed towards RecA inactivation via ATP binding inhibition described a variety of micromolar affinity ligands, inhibitors of the DNA binding site are still unknown...

This study aims at evaluating the utility of the population pharmacokinetics approach in therapeutic protein drug-drug-interaction (DDI) assessment. Simulations were conducted for 2 representative victim drugs, methotrexate and trastuzumab, using a parallel-group design with and without the interaction drug. The effect of a perpetrator on the exposure of the victim drug is described as the ratio of clearance/apparent clearance of the victim drug given with or without the perpetrator. The power of DDI assessment was calculated as the percentage of runs with 90% confidence interval of the estimated DDI effect within 80% to 125% for the scenarios of no DDI, benchmarked with the noncompartmental approach with intensive sampling...
