Abstract
Background This study aimed to describe the anatomy of maxillary canines from a Western Mexican sub-population using micro-computed tomography (micro-CT). Material and Methods Maxillary canines (n=32) were scanned at 19.6µm voxel resolution. Number and location of canals, the distance between the cemento-enamel junction and apex, occurrence of accessory and lateral canals, presence of oval canals, number of foraminas as well as two- (area, perimeter, roundness, aspect ratio, major and minor diameters) and three-dimensional (volume, surface area, and SMI) analysis were performed. Data of two-dimensional analyses at 5 different apical levels was statistically compared using Kruskal-Wallis tests (α=0.05). Results Overall, 31 specimens had one root with a main canal (Vertucci type I). Mean distance from the apex to the cemento-enamel junction was 16.32±2.27. Apical foraminas were present in 14 specimens (43.75%). No statistical differences were found in the two-dimensional analyses between the foramen and the 1 and 2mm apical levels (P >0.05). Conclusions Maxillary canines presenting one root canal were present in a high percentage of cases (96%). The prevalence of long oval canals was <12% at the apical third and at least 37% of the sample showed more than one point of exit in the last apical 3mm. Key words:Maxillary canine, micro-computed tomography, root canal anatomy.

Abstract
Depending on disease stage follicular lymphoma (FL) lack the t(14;18) in ~15-~50% of cases. Nevertheless, most of these cases express BCL2. To elucidate mechanisms triggering BCL2 expression and promoting pathogenesis in t(14;18)-negative FL, exonic single-nucleotide variant (SNV) profiles of 28 t(14;18)-positive and 13 t(14;18)-negative FL were analyzed, followed by the integration of copy-number changes, copy-neutral LOH and published gene-expression data as well as the assessment of immunoglobulin N-glycosylation sites. Typical FL mutations also affected t(14;18)-negative FL. Curated gene set/pathway annotation of genes mutated in either t(14;18)-positive or t(14;18)-negative FL revealed a strong enrichment of same or similar gene sets but also a more prominent or exclusive enrichment of immune response and N-glycosylation signatures in t(14;18)-negative FL. Mutated genes showed high BCL2 association in both subgroups. Among the genes mutated in t(14;18)-negative FL 555 were affected by copy-number alterations and/or copy-neutral LOH and 96 were differently expressed between t(14;18)-positive and t(14;18)-negative FL (P<0.01). N-glycosylation sites were detected considerably less frequently in t(14;18)-negative FL. These results suggest a diverse portfolio of genetic alterations that may induce or regulate BCL2 expression or promote pathogenesis of t(14;18)-negative FL as well as a less specific but increased crosstalk with the microenvironment that may compensate for the lack of N-glycosylation.

Abstract
Wastewater produced in pharmaceutical manufacturing plants (PMPs), especially the one coming from organic-synthesis facilities, is characterized by its large variability due to the wide range of solvents and chemical reagents used in the different stages of the production of medicines. Normally, the toxicity of the organic compounds prevent the utilization of biological processes and more powerful treatments are needed becoming advanced oxidation processes (AOPs) a valid alternative. In this work, the efficiency in abatement of pollution by Fenton oxidation (FO) and conductive-diamond electro-oxidation (CDEO) are compared in the treatment of 60 real effluents coming from different processes carried out in a pharmaceutical facility, using standardized tests. In 80% of the samples, CDEO was found to be more efficient than FO and in the remaining 20%, coagulation was found to exhibit a great significance in the COD abatement mechanism during FO, pointing out the effectiveness of the oxidation promoted by the electrochemical technology. Mean oxidation state of carbon was found to be a relevant parameter to understand the behavior of the oxidation technologies. It varied inversely proportional to efficiency in FO and it showed practically no influence in the case of CDEO.

Abstract
The management of patients with pancreatic cancer has advanced over the last few years. We convey a multidisciplinary group of experts in an attempt to stablish practical guidelines for the diagnoses, staging and management of these patients. This paper summarizes the main conclusions of the working group. Patients with suspected pancreatic ductal adenocarcinoma should be rapidly evaluated and referred to high-volume centers. Multidisciplinary supervision is critical for proper diagnoses, staging and to frame a treatment plan. Surgical resection together with chemotherapy offers the highest chance for cure in early stage disease. Patients with advanced disease should be classified in treatment groups to guide systemic treatment. New chemotherapeutic regimens have resulted in improved survival. Symptomatic management is critical in this disease. Enrollment in a clinical trial is, in general, recommended.

Abstract
Background: To develop and validate a nomogram and web-based calculator to predict overall survival (OS) in Caucasian-advanced oesophagogastric adenocarcinoma (AOA) patients undergoing first-line combination chemotherapy. Methods: Nine hundred twenty-four AOA patients treated at 28 Spanish teaching hospitals from January 2008 to September 2014 were used as derivation cohort. The result of an adjusted-Cox proportional hazards regression was represented as a nomogram and web-based calculator. The model was validated in 502 prospectively recruited patients treated between October 2014 and December 2016. Harrell's c-index was used to evaluate discrimination. Results: The nomogram includes seven predictors associated with OS: HER2-positive tumours treated with trastuzumab, Eastern Cooperative Oncology Group performance status, number of metastatic sites, bone metastases, ascites, histological grade, and neutrophil-to-lymphocyte ratio. Median OS was 5.8 (95% confidence interval (CI), 4.5–6.6), 9.4 (95% CI, 8.5–10.6), and 14 months (95% CI, 11.8–16) for high-, intermediate-, and low-risk groups, respectively (P<0.001), in the derivation set and 4.6 (95% CI, 3.3–8.1), 12.7 (95% CI, 11.3–14.3), and 18.3 months (95% CI, 14.6–24.2) for high-, intermediate-, and low-risk groups, respectively (P<0.001), in the validation set. The nomogram is well-calibrated and reveals acceptable discriminatory capacity, with optimism-corrected c-indices of 0.618 (95% CI, 0.591–0.631) and 0.673 (95% CI, 0.636–0.709) in derivation and validation groups, respectively. The AGAMENON nomogram outperformed the Royal Marsden Hospital (c-index=0.583; P=0.00046) and Japan Clinical Oncology Group prognostic indices (c-index=0.611; P=0.03351). Conclusions: We developed and validated a straightforward model to predict survival in Caucasian AOA patients initiating first-line polychemotherapy. This model can contribute to inform clinical decision-making and optimise clinical trial design.

Abstract
Subcutaneous larvae of Hypoderma spp. (Diptera: Oestridae) were detected in the dorsal region in 10 roe deer, Capreolus capreolus (Artiodactyla: Cervidae), hunted in central Spain between January and March 2016. All larvae were found in the inner side of the hide during the skinning of the animals. The study of the morphological features of eight larvae of different stages collected from two animals allowed the identification of Hypoderma actaeon Brauer. The small size (4-5 mm) of some of the first instars suggests that the internal lifecycle of H. actaeon may be exclusively subcutaneous. This is the first confirmation of H. actaeon in roe deer; however, further studies to assess the spread of the parasite and to follow the evolution of this myiasis in roe deer are needed.

Abstract
Understanding how monogenetic volcanic systems work requires full comprehension of the local and regional stresses that govern magma migration inside them and why/how they seem to change from one eruption to another. During the 2011–2012 El Hierro eruption (Canary Islands) the characteristics of unrest, including a continuous change in the location of seismicity, made the location of the future vent unpredictable, so short term hazard assessment was highly imprecise. A 3D P-wave velocity model is obtained using arrival times of the earthquakes occurred during that pre-eruptive unrest and several latter post-eruptive seismic crises not related to further eruptions. This model reveals the rheological and structural complexity of the interior of El Hierro volcanic island. It shows a number of stress barriers corresponding to regional tectonic structures and blocked pathways from previous eruptions, which controlled ascent and lateral migration of magma and, together with the existence of N-S regional compression, reduced its options to find a suitable path to reach the surface and erupt.

Abstract
Although several T cell-mediated autoimmune diseases have shown a reduction in their clinical disease activity during pregnancy, the underlying mechanisms by which pregnancy causes such a beneficial effect on the disease activity are not fully understood. We performed a longitudinal study of chemokine receptors (CCR3, CCR4, CCR5, CXCR3, CXCR4) by flow cytometry in different subsets of peripheral blood mononuclear cells (PBMC) during pregnancy in multiple sclerosis (MS) patients. The levels of cytokine mRNA expression (IL-10, IFN-g) were also investigated by real-time quantitative reverse transcription polymerase chain reaction. The expression of CXCR3 by CD4 and CD8 positive T cells was decreased to a statistically significant extent during the second trimester of pregnancy. CD4 and CD8 T cells showed a statistically significant increase in the expression of CXCR4 during the third trimester of pregnancy. At the mRNA expression level, an increase in the IL-10/IFN-g ratio was observed during pregnancy, especially during the third trimester. These findings indicate immunomodulatory effects of pregnancy on the expression of chemokine receptors and cytokines, which may be related to changes in the clinical disease activity of T cell-mediated autoimmune diseases, such as MS.

Abstract
Hepatocellular carcinoma (HCC) represents the second leading cause of cancer-related death worldwide. Surveillance with abdominal ultrasound every 6 months should be offered to patients with a high risk of developing HCC: Child-Pugh A-B cirrhotic patients, all cirrhotic patients on the waiting list for liver transplantation, high-risk HBV chronic hepatitis patients (higher viral load, viral genotype or Asian or African ancestry) and patients with chronic hepatitis C and bridging fibrosis. Accurate diagnosis, staging and functional hepatic reserve are crucial for the optimal therapeutic approach. Characteristic findings on dynamic CT/MR of arterial hyperenhancement with "washout" in the portal venous or delayed phase are highly specific and sensitive for a diagnosis of HCC in patients with previous cirrhosis, but a confirmed histopathologic diagnosis should be done in patients without previous evidence of chronic hepatic disease. BCLC classification is the most common staging system used in Western countries. Surgical procedures, local therapies and systemic treatments should be discussed and planned for each patient by a multidisciplinary team according to the stage, performance status, liver function and comorbidities. Surgical interventions remain as the only curative procedures but both local and systemic approaches may increase survival and should be offered to patients without contraindications.

Abstract
PURPOSE Previous studies have shown that docetaxel and cisplatin, as single agents, are effective and relatively well tolerated in patients with advanced gastric cancer. The aim of this study was to assess efficacy and toxicity of a biweekly regimen of docetaxel plus cisplatin in patients with advanced gastric cancer. PATIENTS/METHODS Fifty-five patients with histologically proven advanced gastric cancer with at least 1 measurable lesion and ECOG PS ≤ 2 were enrolled. Patients received docetaxel 50 mg/m(2) and cisplatin 50 mg/m(2) every 2 weeks until progression disease, unbearable toxicity or a maximum of 12 cycles. RESULTS In total, 426 cycles were administered (median 8.5 cycles) to 52 evaluable patients. One patient (1.9 %) showed a complete response, while 21 (40.4 %) had partial responses. The objective response rate was 42.3 % (95 % CI 28.9-55.7), the median time to progression was 5.5 months (95 % CI 4.0-7.0), and the median overall survival was 8.9 months (95 % CI 6.0-11.9). The most common grade 3-4 toxicities per cycle were haematological [neutropenia (5.9 %)]. CONCLUSIONS Biweekly administration of docetaxel and cisplatin in advanced gastric cancer has a manageable toxicity profile and shows a promising antitumour activity as a first-line therapy.

[PMID: 26185893 DOI: 10.1016/j.cyto.2015.07.008] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2015] [Revised: 07/06/2015] [Accepted: 07/08/2015] [Indexed: 11/18/2022]
Abstract
OBJECTIVES To study, in normal cartilage explants (CEs) challenged with lipopolysaccharide (LPS), the temporal effects (at 48 and 96h) of leukocyte- and platelet-rich gel (L-PRG) and pure platelet-rich gel (P-PRG) supernatants on the production and degradation of platelet-associated growth factors (GFs) (platelet-derived GF isoform BB [PDGF-BB] and transforming growth factor beta-1 [TGF-β1]), pro-inflammatory (tumour necrosis factor alpha [TNF-α]) and anti-inflammatory cytokines (interleukin 4 [IL-4] and IL-1 receptor antagonist [IL-1ra]). METHODS CEs from six horses were challenged with LPS and cultured for 96h with L-PRG and P-PRG supernatants at concentrations of 25% and 50%, respectively. The CE culture medium was changed every 48h and used for determination, by ELISA, of PDGF-BB, TGF-β1, TNF-α, IL-4 and IL-1ra. RESULTS Both the 25% and 50% PRG supernatants produced a different molecular profile in the culture media, unlike that of the CE challenged with LPS only. 50% L-PRG produced the most sustained release of growth factors and anti-inflammatory cytokines, although it produced the highest TNF-α release. PDGF-BB was significantly correlated with IL-1ra and TNF-α concentrations, whereas TNF-α was correlated with IL-4. CONCLUSIONS 50% L-PRG supernatant produced a more sustained concentration of growth factors and anti-inflammatory cytokines than the other hemoderivatives evaluated. This substance could be evaluated in animal models of arthritis or in patients with arthropathies.

Abstract
AIM The goal of this study was to determine reference values of explosive strength for Spanish professional athletes using a force platform. Reference values are displayed as a sports-independent percentile distribution. METHODS A total of 323 elite male athletes (age: 20.38 ± 4.65 years, body mass: 75.04 ± 14.30 kg, height: 178.62 ± 14.18 cm) from different disciplines performed the following test: squat jump (SJ), countermovement jump (CMJ), Abalakov test (AB), drop jump (DJ) and repeated jumps (RJ). We calculated: relative peak power, relative peak force, maximal height, symmetry index, explosive index of strength, relative effective impulse, duration of jump, elastic capacity, eccentric time, action of arm, jump number, average height, intensity and fatigue index of force. RESULTS Significant differences were found among sports disciplines (P<0.05) in relative peak power, maximal height and relative effective impulse during the SJ, CMJ and AB tests. No significant differences were found among disciplines in DJ variables. In RJ, the main variable characterizing the disciplines analyzed was average height, which showed a significant negative association with athletics, soccer, volleyball and gymnastics. CONCLUSION The results obtained suggest that a percentile table may be useful in assessing explosive strength in athletes, regardless of there being any reference values available for their sports discipline.

Abstract
OBJECTIVES To determine the reasons of prescription, the characteristics of patients and factors that affected the outcome of critically ill patients treated with micafungin (MCF) during their stay in Spanish ICUs. MATERIAL AND METHODS Observational, retrospective and multicenter study. Patients admitted to the ICU between March 2011 and October 2012 (20-month period) treated with MCF for any reason were included in the study. Severity of patients at the beginning of treatment was measured with the APACHE II, SOFA, Child-Pugh and MELD scores. Reasons for the use of MCF were classified as prophylaxis, preemptive treatment, empirical treatment and directed treatment. Continuous variables are expressed as mean and standard deviation or median, and categorical variables as percentages. A multivariate analysis was performed to identify variables related to intra-ICU mortality. RESULTS The study population included 139 patients admitted to 19 Spanish ICUs, with a mean age of 57.3 (17.1) years, 89 (64%) men, with surgical (53.2%) and/or medical (44.6%) conditions, APACHE II score of 20.6 (7.7) and SOFA score of 8.4 (4.3), with 84.2% of patients requiring mechanical ventilation, 59% parenteral nutrition, 37.4% extrarenal depuration procedures and 37.4% treatment with steroids. MCF was indicated as empirical treatment of a proven infection in 51 (36.7%) cases, pre-emptive treatment in 50 (36%) especially as a result of the application of the Candida score (32 cases), directed treatment of fungal infection in 23 (16.5%) and as prophylactic treatment in 15 (10.8%) cases. In 108 (77%) cases, a daily dose of 100mg was administered, with a loading dose in only 9 cases (6.5%). The mean duration of treatment was 13.1 (13) days. A total of 59 (42.4%) patients died during their stay in the ICU and 16 after ICU discharge (hospital mortality 53.9%). Independent risk factors for intra-ICU mortality were the Child-Pugh score (OR 1.45, 95% CI 1.162-1.813; P=.001) and the MELD score (OR 1.05, 95% CI 1.011-1.099; P=.014). CONCLUSIONS MCF is usually administered at a dose of 100mg/day, without loading dose and in 72.7% of cases as pre-emptive or empirical treatment. Factors that better predicted mortality were indicators of liver insufficiency at the time of starting treatment.

Abstract
This paper reports the results of the survey developed after the first detection of protozoan Marteilia sp. infection of the grooved razor shell Solen marginatus (Pulteney, 1799) from Galicia (NW Spain) in 2006. Furthermore, we analysed other parasites and pathological conditions found in grooved razor shell populations throughout this survey, such as metacercariae of trematodes, prokaryotic infections and disseminated neoplasms, some of which could cause moderate or severe damage to the host depending on the intensity of infection. A total of 17 natural beds distributed along the Galician coast were analysed, and Marteilia sp. was detected in 6 of them with low prevalence, moderate intensity and no negative effects over the populations.
