Abstract
BACKGROUND Troponin I is one of the most commonly tested biochemical markers in the emergency room (ER) and in the hospital setting. Besides coronary artery disease (CAD), demand ischemia with underlying tachycardia, anemia, hypertensive emergency, congestive heart failure, kidney disease, sepsis, and pulmonary embolism have also been reported to cause troponin I elevations. Few reports have excluded patients with CAD, and no study has summarized the proportion of these factors relative to an increased troponin I level. METHODS The aim of this retrospective study was to investigate the level of contribution of causative factors in troponin I elevation. Charts of patients tested for troponin I during an ER visit or during hospitalization were collected. Patients with known CAD, abnormal stress tests, cardiac catheterizations, or discharge without an adequate cardiac evaluation were excluded. Logistic regression was used to identify predictors of elevated troponin I levels. RESULTS A total of 586 patients were investigated in this study. Age, hemoglobin (Hb), heart rate (HR), glomerularfiltration rate, atrial fibrillation, congestive heart failure (CHF), and sepsis were significant predictors of elevated troponin I by analysis in univariate logistic regression (all P < .001). In multivariate logistic regression, sepsis, CHF, age, Hb, and HR were independent predictors of troponin I (all P < .01). A simple clinical scoring system was generated with 1 score on patients with age ≥ 60, Hb < 10 g/dL, and HR ≥ 100 beats per minute (bpm). The prevalence of elevated troponin I was 4%, 16%, 38%, and 50% for patients with scores of 0, 1, 2, and 3, respectively. In patients without sepsis and CHF, the chances of elevated troponin I were 2%, 11%, 28%, and 43%. CONCLUSIONS Sepsis was found to be the strongest independent cause of elevated troponin I levels in non-CAD patients. The scoring system composed of age, hemoglobin (Hb), and heart rate (HR) can assist clinical evaluation of elevated troponin I test in non-CAD patients.

Abstract
BACKGROUND Stillbirth is the mayor contributor to perinatal mortality. AIM To report a system for classification of fetal deaths. MATERIAL AND METHODS Retrospective cohort study of 29,916 births with 258 fetal deaths that occurred in a public hospital. Data were obtained from audit reports of stillbirths. The method for classification obstetric condition relevant to the death was applied, based on obstetric and placental pathological findings analyzed exclusively by a single obstetrician and a single pathologist. RESULTS Ninety two percent of obstetric conditions causing fetal death were identified. The most commonly reported were ascending bacterial infection in 26%, congenital anomalies in 19%, arterial hypertension in 12% and placental pathology in 12%. Fetal growth restriction was identified in 50% of stillbirths. Ninety percent were secondary to a primary obstetric condition and 10% had an unexplained cause. Placental abruption as the final cause of fetal death was identified in 60% of cases with arterial hypertension, 43% of cases with placental pathology and 37% of ascending infections. Fetal deaths occurred during pregnancy in 82% of cases and during labor in 17%. Intrapartum asphyxia occurred in 0.8% of stillbirths and presented in term pregnancies. CONCLUSIONS The obstetric condition relevant to the death method for classification of fetal death is effective to identify the originating obstetric cause of stillbirth and reduces the impact of fetal growth restriction and intrapartum asphyxia as the leading causes of death.

Abstract
INTRODUCTION Guillain-Barre syndrome is classically defined as a symmetrical ascending acute polyradiculoneuropathy, although there are atypical variants that make diagnosis difficult. CASE REPORTS The medical data of six patients in our hospital area are collected during the first quarter of 2013. Lumbar punctures, imaging, neurophysiological studies, ganglioside antibodies and serologies have been proposed in all cases. We focus on the atypical features as late hyporeflexia, increased frequency of asymmetry and distal paresis and initial fever. From a neurophysiological point of view, all patients presented sensorimotor axonal forms. The most consistent datas in early studies is the F wave's alteration. A Miller Fisher variant associated with faciocervicobraquial paresis and cerebral reversible vasoconstriction syndrome has been detected. A bilateral brachial paresis and lumbar polyradiculopathy in the context of influenza A infection is other interesting case. The saltatory variant with cranial nerve involvement and lower limbs paresis has been demonstrated in one patient. Bands in cerebrospinal fluid are positive in three cases and anti-ganglioside antibodies in one patient. The syndrome of inappropriate secretion of antidiuretic hormone may explain some of the hyponatremias registered. The first line of treatment are inmunoglobulins in all patients. Plasmapheresis exchanges has been used as an additional therapy in four cases. CONCLUSIONS These clusters of six axonal cases with atypical clinical features justifies the need for knowledge of these variants in order to achieve an early treatment. Late hyporeflexia and brachialfaciocervico, saltatory and lumbar forms should be considered in the spectrum of Guillain-Barre syndrome. The etiological study should rule out a lots of pathogens as influenza A.

A threshold of transmembrane potential is required for mitochondrial dynamic balance mediated by DRP1 and OMA1. Cell Mol Life Sci 2017; 74:1347-1363.

Abstract
As an organellar network, mitochondria dynamically regulate their organization via opposing fusion and fission pathways to maintain bioenergetic homeostasis and contribute to key cellular pathways. This dynamic balance is directly linked to bioenergetic function: loss of transmembrane potential across the inner membrane (Δψ m) disrupts mitochondrial fission/fusion balance, causing fragmentation of the network. However, the level of Δψ m required for mitochondrial dynamic balance, as well as the relative contributions of fission and fusion pathways, have remained unclear. To explore this, mitochondrial morphology and Δψ m were examined via confocal imaging and tetramethyl rhodamine ester (TMRE) flow cytometry, respectively, in cultured 143B osteosarcoma cells. When normalized to the TMRE value of untreated 143B cells as 100%, both genetic (mtDNA-depleted ρ0) and pharmacological [carbonyl cyanide m-chlorophenyl hydrazone (CCCP)-treated] cell models below 34% TMRE fluorescence were unable to maintain mitochondrial interconnection, correlating with loss of fusion-active long OPA1 isoforms (L-OPA1). Mechanistically, this threshold is maintained by mechanistic coordination of DRP1-mediated fission and OPA1-mediated fusion: cells lacking either DRP1 or the OMA1 metalloprotease were insensitive to loss of Δψ m, instead maintaining an obligately fused morphology. Collectively, these findings demonstrate a mitochondrial 'tipping point' threshold mediated by the interaction of Δψ m with both DRP1 and OMA1; moreover, DRP1 appears to be required for effective OPA1 maintenance and processing, consistent with growing evidence for direct interaction of fission and fusion pathways. These results suggest that Δψ m below threshold coordinately activates both DRP1-mediated fission and OMA1 cleavage of OPA1, collapsing mitochondrial dynamic balance, with major implications for a range of signaling pathways and cellular life/death events.

Abstract
The small (16,569 base pair) human mitochondrial genome plays a significant role in cell metabolism and homeostasis. Mitochondrial DNA (mtDNA) contributes to the generation of complexes which are essential to oxidative phosphorylation (OXPHOS). As such, mtDNA is directly integrated into mitochondrial biogenesis and signaling and regulates mitochondrial metabolism in concert with nuclear-encoded mitochondrial factors. Mitochondria are a highly dynamic, pleiomorphic network that undergoes fission and fusion events. Within this network, mtDNAs are packaged into structures called nucleoids which are actively distributed in discrete foci within the network. This sensitive organelle is frequently disrupted by insults such as oxidants and inflammatory cytokines, and undergoes genomic damage with double- and single-strand breaks that impair its function. Collectively, mtDNA is emerging as a highly sensitive indicator of cellular stress, which is directly integrated into the mitochondrial network as a contributor of a wide range of critical signaling pathways.

Abstract
OBJECTIVES To evaluate the use of 4D PET/CT to quantify tumor respiratory motion compared to the «Slow»-CT (CTs) in the radiotherapy planning process. MATERIAL AND METHODS A total of 25 patients with inoperable early stage non small cell lung cancer (NSCLC) were included in the study. Each patient was imaged with a CTs (4s/slice) and 4D PET/CT. The adequacy of each technique for respiratory motion capture was evaluated using the volume definition for each of the following: Internal target volume (ITV) 4D and ITVslow in relation with the volume defined by the encompassing volume of 4D PET/CT and CTs (ITVtotal). The maximum distance between the edges of the volume defined by each technique to that of the total volume was measured in orthogonal beam's eye view. RESULTS The ITV4D showed less differences in relation with the ITVtotal in both the cranio-caudal and the antero-posterior axis compared to the ITVslow. The maximum differences were 0.36mm in 4D PET/CTand 0.57mm in CTs in the antero-posterior axis. 4D PET/CT resulted in the definition of more accurate (ITV4D/ITVtotal 0.78 vs. ITVs/ITVtotal 0.63), and larger ITVs (19.9 cc vs. 16.3 cc) than those obtained with CTs. CONCLUSION Planning with 4D PET/CT in comparison with CTs, allows incorporating tumor respiratory motion and improving planning radiotherapy of patients in early stages of lung cancer.

Abstract
Objective: To evaluate the psychometric properties of the Modified Fatigue Impact Scale (MFIS) in four different European countries. Methods: Individuals with definite multiple sclerosis (MS) were selected from centres in Italy (n=50), Spain (n=30), Slovenia (n=50) and Belgium (n=51) and completed the MFIS and the Fatigue Severity Scale (FSS) twice (interval ≤ 3 days). Results: In all four samples, the MFIS demonstrated a good reproducibility (intraclass correlation coefficient ≥ 0.84), with no significant differences between countries (P=0.77). Moderate correlations were found between the MFIS and FSS. No significant correlations were found between the MFIS and age, gender, type of MS, duration of the disease or EDSS score. Factor analysis of all samples (n=181) could not completely confirm the original assumptions concerning the physical, cognitive and psychosocial component. The total score, the physical and the cognitive subscale of the scale were homogeneous (Cronbach’s alpha 0.92, 0.88 and 0.92, respectively), but the psychosocial subscale had a Cronbach’s alpha of 0.65. Conclusions: No cultural or linguistic differences were found in the psychometric properties of the Belgian, Italian, Slovenian or Spanish version of the MFIS. We recommend this scale for research purposes and in clinical practice. Due to the limited value of the psychosocial subscale, we recommend interpreting this subscale with caution.

Abstract
A 114.5m deep drilling was carried out in August 2000 in the bedrock of the Veleta peak, at 3380m in the massif of Sierra Nevada, Southern Spain. The objective of this work is to analyse temperatures at the first 60m depth of this drilling from September 2002 to August 2013 based on 11 UTL-1 thermal loggers located at different depths, together with air temperatures at the summit of the Veleta peak. Permanent negative temperatures have not been detected in the borehole, which shows evidence of the absence of widespread permafrost conditions nowadays in the highest lands of this massif. Bedrock temperatures oscillated between 3.2°C at 0.6m depth and 2°C at 20m below the surface. The largest temperature ranges were recorded on the most external sensors until 1.2m depth, where values reached 22.3°C. Seasonal temperature variations were significant until 10m depth. The thickness of the seasonal frozen layer was highly variable (0.6-2m) and dependent on annual climate conditions. The mean air temperature at the Veleta peak increased by 0.12°C during the study period. Bedrock temperatures followed diverging trends: a drop of 0.3-0.4°C down to 0.6m depth, a decrease of up to 0.7°C between 4 and 10m, thermal stability at 20m and a rise of 0.2°C that occurred in 2009 at the deepest sensor at 60m. The calculation of the thermal wave damping in the subsoil of the Veleta peak has allowed for quantifying the thermal diffusivity of the rock as (7.05±0.03)10(-7)m(2)/s, which means that the external climate signal arrives with an 8.5-year lag to the sensor at 60m deep. This allows to deduce a trend change in the climate of the area, moving from warmer conditions towards a trend of cooling from 2006 to 2007.

Abstract
BACKGROUND Docetaxel-cyclophosphamide (TC) has become a common regimen in moderate-high-risk early breast cancer (EBC), but the incidence of chemotherapy-induced nausea and vomiting (CINV) with this regimen is not well established. This trial investigates the effect of guideline-consistent prophylaxis on CINV related to TC regimen and explores the efficacy of aprepitant among resistant patients. PATIENTS AND METHODS This prospective multicentre study enrolled 212 chemotherapy-naïve EBC patients receiving T-75 mg/m(2) and C-600 mg/m(2). Antiemetic therapy on the first cycle consisted of dexamethasone for 3 d plus 5-hydroxytryptamine (5-HT3) antagonists on day 1, according to Multinational Association of Supportive Care in Cancer guidelines. The primary end-point was complete response (CR) (no emesis and no need of rescue treatment within the initial 120 h). Patients failing CR on cycle 1 entered in a single-arm study exploring the efficacy of aprepitant on the second cycle. Patients' diaries and Functional Living Index-Emesis (FLIE) questionnaires were collected in cycles 1 and 2. RESULTS Among the 185 evaluable patients on cycle 1, 161 (87%, 95% confidence interval [CI]: 82.2-91.8) achieved a CR. Twenty-three patients received aprepitant on cycle 2, and 12 reached a CR (52.2%, 95% CI: 31.8-72.6). The absence of CR had a very substantial impact on quality of life on cycles 1 (FLIE before and after: 23.8-38.1, p = 0.0124) and 2 (18.3-42.9, p = 0.0059). CONCLUSIONS Guideline-consistent antiemetic prophylaxis for the TC regimen is associated with a low incidence of CINV. Aprepitant is effective as secondary prevention of CINV and should be considered as rescue therapy in patients treated with moderate emetogenic chemotherapy.
