Safety and efficacy of personalised versus standard dosing of linezolid in patients with sepsis (SePkLin): a pragmatic, multicentre, randomised, controlled and superiority clinical trial protocol.

Introduction: Linezolid is a broadly used antibiotic to treat complicated infections caused by gram-positive bacteria. Therapeutic drug monitoring of linezolid concentrations is recommended to maximise its efficacy and safety, mainly haematological toxicity. Different pharmacokinetic/pharmacodynamic targets have been proposed to improve linezolid exposure: the ratio of the area under the concentration-time curve during a 24-hour period to minimum inhibitory concentration (MIC) between 80 and 120; percentage of time that the drug concentration remains above the MIC during a dosing interval greater than 85% and the trough concentration between 2 and 7 mg/L.

Dasatinib-induced spleen contraction leads to transient lymphocytosis.

The tyrosine kinase inhibitor dasatinib is approved for Philadelphia chromosome-positive leukemia, including chronic myeloid leukemia (CML). Although effective and well tolerated, patients typically exhibit a transient lymphocytosis after dasatinib uptake. To date, the underlying physiological process linking dasatinib to lymphocytosis remains unknown.

Early molecular markers of ventilator-associated pneumonia in bronchoalveolar lavage in preterm infants.

Introduction: Ventilator-associated pneumonia (VAP) constitutes a serious nosocomial infection. Our aim was to evaluate the reliability of cytokines and oxidative stress/inflammation biomarkers in bronchoalveolar lavage fluid (BALF) and tracheal aspirates (TA) as early biomarkers of VAP in preterm infants.

Methods: Two cohorts were enrolled, one to select candidates and the other for validation.

Higher versus Lower Oxygen Concentration during Respiratory Support in the Delivery Room in Extremely Preterm Infants: A Pilot Feasibility Study.

Background: Optimal starting oxygen concentration for delivery room resuscitation of extremely preterm infants (<29 weeks) remains unknown, with recommendations of 21-30% based on uncertain evidence. Individual patient randomized trials designed to answer this question have been hampered by poor enrolment.

Hypothesis: It is feasible to compare 30% vs.

Toxic Elements in Traditional Kohl-Based Eye Cosmetics in Spanish and German Markets.

Kohl is a traditional cosmetic widely used in Asia and Africa. In recent years, demand for kohl-based eyelids and lipsticks has increased in Europe, linked to migratory phenomena of populations from these continents. Although the European legislation prohibits the use of heavy metals in cosmetics due to the harmful effects to human health, particularly to pregnant women and children, these elements are still present in certain products.

Maternal Hair and Neonatal Meconium to Assess Gestational Consumption and Prenatal Exposure to Drugs of Abuse and Psychoactive Drugs.

Background: In the last two decades, the consumption of drugs of abuse among women of childbearing age has experienced a significant increase and results from analyses of surveys concerning maternal intake of psychoactive prescription drugs during pregnancy indicate that the rates of intake are increasing each year. Analyses of biological matrices such as maternal hair and neonatal meconium have recently been used for assessment of gestational consumption and consequent prenatal exposure to drugs of abuse in high-risk groups of women.

Methods: Maternal hair and neonatal meconium were analyzed by validated chromatographic-mass spectrometric methodologies to disclose the gestational use of drugs of abuse and psychoactive prescription drugs and consequent prenatal exposure in a cohort of 513 mother-newborn dyads at the Sant Joan de Déu Barcelona Hospital, Spain, during 2012-2013.

Identification and replication of the interplay of four genetic high-risk variants for urinary bladder cancer.

Little is known whether genetic variants identified in genome-wide association studies interact to increase bladder cancer risk. Recently, we identified two- and three-variant combinations associated with a particular increase of bladder cancer risk in a urinary bladder cancer case-control series (Leibniz Research Centre for Working Environment and Human Factors at TU Dortmund (IfADo), 1501 cases, 1565 controls). In an independent case-control series (Nijmegen Bladder Cancer Study, NBCS, 1468 cases, 1720 controls) we confirmed these two- and three-variant combinations.

Heavy metals exposure levels and their correlation with different clinical forms of fetal growth restriction.

Background: Prenatal heavy metals exposure has shown a negative impact on birth weight. However, their influence on different clinical forms of fetal smallness was never assessed.

Objectives: To investigate whether there is a differential association between heavy metals exposure and fetal smallness subclassification into intrauterine growth restriction (IUGR) and small-for-gestational age (SGA).

Common Polymorphisms in Relation to Survival among Small Cell Lung Cancer Patients: A Multicenter Study from the International Lung Cancer Consortium.

DNA topoisomerase inhibitors are commonly used for treating small-cell lung cancer (SCLC). Tyrosyl-DNA phosphodiesterase (TDP1) repairs DNA damage caused by this class of drugs and may therefore influence treatment outcome. In this study, we investigated whether common single-nucleotide polymorphisms (SNP) are associated with overall survival among SCLC patients.

Adherence to nutrition-based cancer prevention guidelines and breast, prostate and colorectal cancer risk in the MCC-Spain case-control study.

Prostate, breast and colorectal cancer are the most common tumours in Spain. The aim of the present study was to evaluate the association between adherence to nutrition-based guidelines for cancer prevention and prostate, breast and colorectal cancer, in the MCC-Spain case-control study. A total of 1,718 colorectal, 1,343 breast and 864 prostate cancer cases and 3,431 population-based controls recruited between 2007 and 2012, were included in the present study.

Survey of neonatal resuscitation practices showed post-training improvements but need to reinforce preterm management, monitoring and adrenaline use.

Aim: Neonatal resuscitation surveys have showed practice variations between countries, centres and levels of care. We evaluated delivery room practices after a nationwide neonatal resuscitation training programme focused on nontertiary centres.

Methods: A 2012 survey sent to all Spanish hospitals handling deliveries covered staff availability and training, equipment and practices in the delivery room and during transfers to neonatal intensive care units.

Sepsis in preterm infants causes alterations in mucosal gene expression and microbiota profiles compared to non-septic twins.

Sepsis is a life-threatening condition in preterm infants. Neonatal microbiota plays a pivotal role in the immune system maturation. Changes in gut microbiota have been associated to inflammatory disorders; however, a link with sepsis in the neonatal period has not yet been established.
