Everolimus Through Plasmatic Concentrations in Cancer Patients: Prospective Longitudinal Observational Multicentric Study (DIANA-1 Project).

Everolimus, an oral inhibitor of the mammalian target of rapamycin (mTOR), is actually used to prevent organ transplant rejection and treat metastatic breast, renal, and neuroendocrine cancers. Despite significant pharmacokinetic variability among patients, routine therapeutic drug monitoring (TDM) is not commonly used in oncology. The aim of this multicenter, prospective observational cohort study is to assess the prevalence of everolimus minimum concentration at a steady state (Cminss) falling outside the therapeutic range (10-26.

Executive summary of the SEEN (Sociedad Española de Endocrinología y Nutrición[Spanish Society of Endocrinology and Nutrition])-SEGO (Sociedad Española deGinecología y Obstetricia [Spanish Society of Gynaecology and Obstetrics]) consensusdocument on the management of thyroid dysfunction during pregnancy.

During pregnancy, thyroid function disorders are associated with multiple complications, both maternal and foetal. In recent years, numerous Clinical Practice Guidelines have been developed to facilitate the identification and correct management of thyroid disease in pregnant women. However, this proliferation of guidelines has led to confusion by proposing different cut-off points for reference values and different recommendations for similar situations.

Impact of Dietary Habit, Iodine Supplementation and Smoking Habit on Urinary Iodine Concentration During Pregnancy in a Catalonia Population.

(1) Background: The nutritional status of women during pregnancy can have a considerable effect on maternal and fetal health, and on the perinatal outcome. Aim: to assess the changes occurring in dietary iodine intake, potassium iodide supplementation, and smoking habit, and the impact of these changes on the urinary iodine concentration (UIC) during pregnancy in a population of women in Catalonia (Spain). (2) Methods: Between 2009-2011, an observational study included a cohort of women whose pregnancies were monitored in the public health system in the Central and North Metropolitan areas of Catalonia.

Daptomycin Plus Fosfomycin Versus Daptomycin Alone for Methicillin-resistant Staphylococcus aureus Bacteremia and Endocarditis: A Randomized Clinical Trial.

Background: We aimed to determine whether daptomycin plus fosfomycin provides higher treatment success than daptomycin alone for methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and endocarditis.

Methods: A randomized (1:1) phase 3 superiority, open-label, and parallel group clinical trial of adult inpatients with MRSA bacteremia was conducted at 18 Spanish hospitals. Patients were randomly assigned to receive either 10 mg/kg of daptomycin intravenously daily plus 2 g of fosfomycin intravenously every 6 hours, or 10 mg/kg of daptomycin intravenously daily.

Intravenous supplementation type and volume are associated with 1-year outcome and major complications in patients with chronic intestinal failure.

Background And Aim: No marker to categorise the severity of chronic intestinal failure (CIF) has been developed. A 1-year international survey was carried out to investigate whether the European Society for Clinical Nutrition and Metabolism clinical classification of CIF, based on the type and volume of the intravenous supplementation (IVS), could be an indicator of CIF severity.

Methods: At baseline, participating home parenteral nutrition (HPN) centres enrolled all adults with ongoing CIF due to non-malignant disease; demographic data, body mass index, CIF mechanism, underlying disease, HPN duration and IVS category were recorded for each patient.

Interplay between BMPs and Reactive Oxygen Species in Cell Signaling and Pathology.

The integration of cell extrinsic and intrinsic signals is required to maintain appropriate cell physiology and homeostasis. Bone morphogenetic proteins (BMPs) are cytokines that belong to the transforming growth factor-β (TGF-β) superfamily, which play a key role in embryogenesis, organogenesis and regulation of whole-body homeostasis. BMPs interact with membrane receptors that transduce information to the nucleus through SMAD-dependent and independent pathways, including PI3K-AKT and MAPKs.

Comparative efficacies of cloxacillin-daptomycin and the standard cloxacillin-rifampin therapies against an experimental foreign-body infection by methicillin-susceptible Staphylococcus aureus.

We compared the efficacies of daptomycin (doses equivalent to 8 to 10 mg/kg of body weight/day in humans) and cloxacillin alone with those of cloxacillin-rifampin and cloxacillin-daptomycin combinations, using a tissue cage methicillin-susceptible Staphylococcus aureus (MSSA) infection model. Monotherapies were less effective than combinations (P<0.05), and daptomycin resistance emerged.

Functional clustering of metastasis proteins describes plastic adaptation resources of breast-cancer cells to new microenvironments.

To examine the molecular mechanisms underlying breast cancer metastasis in liver and search for potential markers of metastatic progression in soft-tissue, we analyzed metastatic variants developed from the highly metastatic MDA-MB 435 cell line through in vivo stepwise selection in the athymic mice. Comparative proteomic analysis using two-dimensional electrophoresis (2DE-DIGE) revealed that 74 protein spots were reproducibly more than doubled in liver metastatic cells compared to parental counterpart. From 22 proteins identified by MALDI-TOF, belonging to intermediate filaments, intracellular transport and ATP synthesis, we generated a protein-protein interaction network containing 496 nodes, 12 of which interacted.

Community-acquired methicillin-resistant Staphylococcus aureus infections: an emerging threat in Spain.

Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) has not been recognised previously as a cause of MRSA infections in Spain. Nineteen patients carrying Panton-Valentine leukocidin (PVL)-positive MRSA were identified in a Barcelona hospital, of whom 15 were immigrants, mostly from South America. Twelve developed skin and soft-tissue infections.

Noninvasive positive pressure ventilation prevents postoperative pulmonary complications in chronic ventilators users.

Objective: To evaluate the postoperative pulmonary complications and the long-term impact on pulmonary function of different surgical procedures with general anaesthesia in chronic respiratory failure (CRF) patients who were using noninvasive positive pressure ventilation (NPPV).

Design: We retrospectively studied 20 stable patients on NPPV for CRF secondary to: kyphoscoliosis (eight), morbid obesity (six), thoracoplasty (four), neuromuscular diseases (two), who underwent surgical procedures with general anaesthesia, between January 1998 and December 2003.

Material And Methods: The variables studied were: type of surgery, hours of orotracheal intubation, hours of stay in the postsurgical reanimation unit (PRU), postoperative pulmonary complications and days of hospital stay.

The role of color duplex sonography in the diagnosis of giant cell arteritis.

Objective: To determine the clinical usefulness of color duplex sonography in the diagnosis of giant cell arteritis as an alternative to temporal artery biopsy.

Methods: From May 1998 to November 2002, 68 consecutive patients seen in our hospital with a clinical suggestion of active temporal arteritis were included. Forty-eight patients were female and 20 were male, with a mean age of 77 years.

The authors present the characteristics which must be considered when selecting an instrument, what its basic requirements are, and what kinds of instruments are currently on the market. Bags and accessories are other sections included in this article.

[Oral, mandibular and oropharyngeal reconstruction with a pedicled trapezius flap].

Reconstruction of large defects of the oral cavity (with or without jaw defects) and the oropharynx is one of the most important challenges in reconstructive maxillofacial surgery. Many reconstruction techniques have been proposed although none has provided total satisfaction. For each patient, accurate evaluation is required to choose the optimal solution.
