INTRODUCTION: Healthcare professionals tend to consider common non-alarming drug-related symptoms to be of little clinical relevance. However, such symptoms can have a substantial impact on the individual patient. Insight into patient-reported symptoms could aid pharmacists to identify improvements in medication treatment, for instance in the patient interview at the start of a clinical medication review (CMR). OBJECTIVE: The objectives of this study were to describe the numbers and types of patient-reported symptoms assessed during a CMR and to elucidate their potential association with the drugs in use...

Microreservoir-type transdermal drug delivery systems (MTDDS) can prevent drug crystallization; however no current predictive model considers the impact of drug load and hydration on their physical stability. We investigated MTDDS films containing polyvinylpyrrolidone (PVP) as polymeric drug stabilizer in lipophilic pressure sensitive adhesive (silicone). Medicated and unmedicated silicone films with different molar N-vinylpyrrolidone (VP):drug ratios were prepared and characterized by FTIR, differential scanning calorimetry (DSC), scanning electron microscopy (SEM), microscopy, Dynamic Vapour Sorption (DVS) and stability testing for four months at different storage conditions...

BACKGROUND: Anemia, a highly prevalent disorder in elderly populations, is associated with numerous adverse health outcomes, including increased mortality, impaired functional status and cognitive disorders. Approximately two-thirds of anemia in American elderly is caused by chronic inflammation or is unexplained. A potential contributing factor may include air pollution exposures, which have been shown to increase systemic inflammation and affect erythropoiesis. Few studies, however, have investigated the associations of air pollution on hemoglobin levels and anemia...

Herein, we report novel high internal phase emulsions and transparent oleogels that exhibit a hierarchical configuration by manipulating the spatial assembly of a natural small molecular-weight quillaja saponin for color performance. Quillaja saponin (QS) is a natural triterpenoid bidesmosidic from the soapbark tree (Quillaja saponaria Molina). Fairly monodispersed QS-coated nanodroplets (∼154 nm) were prepared using the ultrasonic emulsification strategy, and then used as block stabilizers for the fabrication of stable oil-in-water high internal phase emulsions (HIPEs, ϕ = 0...

Heterozygous Fabry females usually have an attenuated form of Fabry disease, causing them to be symptomatic; however, in rare cases, they can present with a severe phenotype. In this study, we report on a 37-year-old woman with acroparesthesia, a dysmorphic face, left ventricular hypertrophy, and intellectual disability. Her father had Fabry disease and died due to chronic renal and congestive cardiac failure. Her paternal uncle had chronic renal failure and intellectual disability, and her paternal aunt was affected with congestive cardiac failure...

Neonatal dried blood spots (DBS) are routinely collected on standard Guthrie cards for all-comprising national newborn screening programs for inborn errors of metabolism, hypothyroidism and other diseases. In Denmark, the Guthrie cards are stored at - 20 °C in the Danish Neonatal Screening Biobank and each sample is linked to elaborate social and medical registries. This provides a unique biospecimen repository to enable large population research at a perinatal level. Here, we demonstrate the feasibility to obtain gene expression data from DBS using next-generation RNA sequencing (RNA-seq)...

A biobased cellulosic scaffold material was made through freeze-drying ice-templating of functionalized cellulosic nanomaterials. The resulting interconnected highly porous scaffold was primarily composed of highly esterified, strong network of ultrathin cellulosic layers. The prepared cellulosic scaffold material displayed multifunctional properties of hydrophobicity, oleophilicity and lipophilicity, which could selectively absorb milkfat, hydrophobic proteins, various organic solvents and oils. Diverse potential for the structural and medical applications, such as tissue engineering, drug delivery, and oil and fat accumulation are proposed...

OBJECTIVE/BACKGROUND: Globally, approximately 50% of patients with multidrug-resistant tuberculosis (MDR-TB) experience treatment failure. MDR-TB treatment is hindered by adverse events, toxicity of the second-line anti-TB drugs, logistics and costs, especially in low-income countries, and problems with medication adherence. Pharmacokinetic variability is also attributed as one of the reasons contributing to treatment failure. In our reference Tuberculosis Center Beatrixoord (University Medical Center Groningen, Groningen, The Netherlands), we strive to individualize treatment of all MDR-TB patients based on drug-susceptibility testing using minimal inhibitory concentrations and pharmacokinetic parameters...

PURPOSE: One of the major hurdles in enabling personalized medicine is obtaining sufficient patient data to feed into predictive models. Combining data originating from multiple hospitals is difficult because of ethical, legal, political, and administrative barriers associated with data sharing. In order to avoid these issues, a distributed learning approach can be used. Distributed learning is defined as learning from data without the data leaving the hospital. PATIENTS AND METHODS: Clinical data from 287 lung cancer patients, treated with curative intent with chemoradiation (CRT) or radiotherapy (RT) alone were collected from and stored in 5 different medical institutes (123 patients at MAASTRO (Netherlands, Dutch), 24 at Jessa (Belgium, Dutch), 34 at Liege (Belgium, Dutch and French), 48 at Aachen (Germany, German) and 58 at Eindhoven (Netherlands, Dutch))...

Primary progressive aphasia (PPA) is a heterogeneous syndrome with various neuropathological causes for which no medical treatment with proven efficacy exists. Basal forebrain (BF) volume loss has been reported in PPA but its relation to cholinergic depletion is still unclear. The primary objective of this study was to investigate whether cholinergic alterations occur in PPA variants and how this relates to BF volume loss. An academic memory clinic based consecutive series of 11 PPA patients (five with the semantic variant (SV), four with the logopenic variant (LV) and two with the nonfluent variant (NFV)) participated in this cross-sectional in vivo PET imaging study together with 10 healthy control subjects...

BACKGROUND: As we endeavour to examine rates of viral suppression in PLHIV, reliable data on ART adherence are needed to distinguish between the respective contributions of poor adherence and treatment failure on high viral load. Self-reported data are susceptible to response bias and although biomarker data on drug presence and concentration can provide a superior, alternative method of measurement, complications due to drug-drug interactions and genetic variations can cause some inaccuracies...

As a result of amphipathic oligomers driven by different forces including hydrophobic interaction, electrostatic interaction, H-bond, and heat, multiscale emulsion particles can be wrapped. In this paper we attempted to use sodium shellac as a novel biobased wrapping material. The H(+), Ca(+), and spray-drying methods were employed to solidify the complex vitamin E (VE) emulsion with sodium shellac to fabricate the beads. The VE loading and encapsulation efficiency were used to evaluate the wrapping process...

REVIEW
Julia Kovaleva
Gastrointestinal endoscopes are medical devices that have been associated with outbreaks of health care-associated infections. Because of the severity and limited treatment options of infections caused by multidrug-resistant Enterobacteriaceae and Pseudomonas aeruginosa, considerable attention has been paid to detection and prevention of these post-endoscopic outbreaks. Endoscope reprocessing involves cleaning, high-level disinfection/sterilization followed by rinsing and drying before storage. Failure of the decontamination process implies the risk of settlement of biofilm producing species in endoscope channels...

Sudden cardiac death (SCD) is a tragic event affecting millions of individuals worldwide. Although several studies have investigated the epidemiology of SCD, these studies may have been affected by reporting and referral biases, which are reflected in the very different incidence rates and causes of deaths that have previously been reported. Among SCD victims aged < 36 years, inherited cardiac diseases are well known to play an important role. However, the extent to which inherited cardiac diseases also play a role in SCD victims aged < 50 years has not been completely described...
