The efficacy of proton pump inhibitor (PPI) medications is highly dependent on plasma concentrations, which varies considerably due to cytochrome P450 (CYP2C19) genetic variation. We conducted a pragmatic, pilot study of CYP2C19 genotype-guided pediatric dosing of PPI medications. Children aged 5-17 years old with gastric-acid-related conditions were randomized to receive either conventional dosing of a PPI or genotype-guided dosing for a total of 12 weeks. Sixty children (30 in each arm) were enrolled and had comparable baseline characteristics...

Jorge Berladi, Pablo M Lamelas
Information of P2Y12 inhibitors in acute coronary syndromes with vein graft angioplasty is limited. This new analysis from the UK database was not able to find significant differences between Clopidogrel, Prasugrel and Ticagrelor. Large trials would be needed to reliably confirm the best antiplatelet regimen in this setting.

This manuscript reported data for total suspended particulate matter (TSPM), particle-bound mercury (PBM), and total gaseous mercury (TGM) in Almadenejos, a rural zone of ancient Hg mining and metallurgical works. Concentrations of TSPM characterize the study site as being a rural area, with levels below 40 μg m-3 during most of the year and sporadic events involving dust intrusions from Africa. Mercury speciation of PM and nearby soils, which contain both cinnabar and organic Hg, confirms that the PM comes from local soil emissions involving the soils polluted by ancient metallurgical works...

BACKGROUND: Transfemoral Transcatheter Aortic Valve Replacement (TAVR) carries a risk of Vascular Complications (VCs) at the access site. The currently used measures for assessing the risk for VCs are not accurate enough, and sometimes fail to predict them. We therefore aimed to examine whether Iliofemoral artery lumen volume (IFV) assessment with 3-dimensional computed tomography (CT) predicts VCs after transfemoral TAVR. METHODS: We identified 45/560 trans-femoral TAVR patients with VC, then performed nearest neighbor 1:1 matching for patients with no VC, matching for age, sex, TAVR year, valve size and type, closure-device, sheath size and peripheral vascular disease...

Immortality is one of the main features of cancer cells. Tumor cells have an unlimited replicative potential, principally due to the holoenzyme telomerase. Telomerase is composed mainly by dyskerin (DKC1), a catalytic retrotranscriptase (hTERT) and an RNA template (hTR). The aim of this work is to develop new inhibitors of telomerase, selecting the interaction between hTR⁻DKC1 as a target. We designed two models of the human protein DKC1: homology and ab initio. These models were evaluated by different procedures, revealing that the homology model parameters were the most accurate...

Integrated water vapor (IWV) data from Global Navigation Satellite Systems (GNSS) and radiosounding (RS) are compared over four sites (Lindenberg, Ny-Ålesund, Lauder and Sodankylä), which are part of the Global Climate Observing System (GCOS) Reference Upper Air Network (GRUAN). Both datasets show an excellent agreement, with a high degree of correlation (R2 over 0.98). Dependences of GNSS-RS differences on several variables are studied in detail. Mean bias error (MBE) and standard deviation (SD) increase with IWV, but in relative term, these variables decrease as IWV increases...

BACKGROUND: Cancer patients are susceptible to recurrent Clostridium difficile infection (CDI) that is increasing globally, necessitating new approaches to prevent fatal consequences. We examined the clinical characteristics of cancer patients with recurrent CDI (RCDI). PATIENTS AND METHODS: A retrospective review of cancer patients with C. difficile-positive test between January 2015 and May 2017 was carried out. CDI was defined as diarrhea and toxigenic C. difficile detection in the stool by nucleic acid amplification test and enzyme immunoassay...

PP1-disrupting peptides (PDPs) are selective chemical modulators of protein phosphatase-1 (PP1) that liberate the active PP1 catalytic subunit from regulatory proteins, thus allowing it to dephosphorylate nearby substrates. Here, we optimized the original cell-active PDP3 for enhanced stability, and obtained insights into the chemical requirements for stabilizing this 23mer peptide for cellular applications. The optimized PDP-Nal was used to dissect the involvement of PP1 in the MAPK signaling cascade. Specifically, we demonstrate in human osteosarcoma (U2OS) cells that pMEK1/2 is a direct substrate of PP1, whereas dephosphorylation of pERK1/2 is indirect and likely mediated through enhanced tyrosine phosphatase activity after PDP-mediated PP1 activation...

PURPOSE: Optic pathway gliomas (OPGs) are low-grade neoplasms that primarily affect children. The management of OPGs remains controversial. Reports on the use of the endoscopic endonasal approach (EEA) in OPGs are extremely limited, and no such reports exist on its utility for pediatric OPGs. Here, we report our results and experience with OPGs treated with the EEA. METHODS: We retrospectively reviewed the medical records of OPG patients who were treated surgically via the EEA at our institutions from 2015 to 2017...

We demonstrate an optimized optical platform for the three-dimensional (3-D) visualization of crystalline lens opacities in vivo in the eyes of patients with different types and grades of cataracts. We developed a prototype long-depth-range swept source optical coherence tomography (SS-OCT) instrument operating at the speed of 50 kA-scans/second and at the central wavelength of 1 μm to perform high-resolution imaging of the whole anterior segment of the eye. Volumetric data sets of cataractous eyes were acquired and processed to obtain contrast-enhanced high-resolution images of lenticular structures and opacifications...

The socio-educational groups (GRUSE) are a health and emotional well-being promotion strategy, from an asset-based positive health approach. They principally target women who attend health centres with signs of discomfort with no organic basis finding. The strategy was evaluated through a quasi-experimental longitudinal design, with a mixed methodology. Information was collected from 228 women with a battery of scales and from an analysis of health system databases. Ten in-depth interviews with women were conducted, and 3 discussion groups with professionals...

Nowadays, more and more vehicles are equipped with communication capabilities, not only providing connectivity with onboard devices, but also with off-board communication infrastructures. From road safety (i.e., multimedia e-call) to infotainment (i.e., video on demand services), there are a lot of applications and services that may be deployed in vehicular networks, where video streaming is the key factor. As it is well known, these networks suffer from high interference levels and low available network resources, and it is a great challenge to deploy video delivery applications which provide good quality video services...

The identification of biological processes related to the regulation of complex traits is a difficult task. Commonly, complex traits are regulated through a multitude of genes contributing each to a small part of the total genetic variance. Additionally, some loci can simultaneously regulate several complex traits, a phenomenon defined as pleiotropy. The lack of understanding on the biological processes responsible for the regulation of these traits results in the decrease of selection efficiency and the selection of undesirable hitchhiking effects...
