Abstract
Abstract
Introduction: Breast cancer is a heterogeneous malignancy and it's possible to identify by simple techniques, such as inmmunohistochemistry, four subtypes with different clinical and biological behavior. Our aim was to evaluate the influence of these subtypes on the local and distant recurrences rates.
Method: data of 954 unilateral breast cancer patients primarily treated with radical or conservative surgery from 2008 to 2014 were obtained from medical records. Breast cancer subtypes were categorized in Luminal A (RE+ and/or RP+, HER2-), Luminal B (RE+ and/or RP+, HER2+ o Ki-67> 14%); HER2 (RE-, RP-, HER2+) and triple negative tumors (TNT) (RE-, RP-, HER2-). Patterns of recurrence for each subtype and clinicopathological variables and the influence of each variable on the overall survival (OS) by the Kaplan-Meier method. In all cases, we determined histological type, grade nuclear (low, intermediate vrs high), tumor size, lymph node involvement
Results: Median age at diagnosis was 52 years (range, 23-95). Of these patients 55% were premenopausal. We found that 522 (56%) of the cases were luminal A breast cancer, 190 (20%) of the cases were triple negative tumors (TNT), luminal B were 73 (8%) and it was HER2-positive in 152 (20%) of cases. Nine patients (3%) had other breast cancer contralateral. In 70% of all the cases were found in locally advanced stages (IIB – IIIC). In 438 (70%) of all the cases were found in locally advanced stages (IIB – IIIC), 773 (81%) patients underwent radical mastectomy and 181 (19%) undergoing conservative surgery. We performed univariate analysis to evaluate recurrence-related factors. Variables included in the analysis clinical stage (I – IIa vs IIb – IIIC; 88% vs 70%; p = 0.001, ), nuclear grade (grade 1, 2 vs 3; 83% vs 62%; p = 0.01) and pathologic response (total vs parcial, stable disease; 76% vs 54%; p = 0.01), and status Her-2 subtype so borderline (positive vs negative; p= 0.079). A univariate survival analysis stratification according to clinicapathologic characteristics. Clinical stage, histologic grade, response to neoadjuvant and tumor size were identified as significant factors of prognosis for the OS. (p=0.5) and histological subtypes Luminal A (94%), Luminal B (75%), HER2 (79%) and TNT (68%), p= 0.001.
Conclusion: this study demonstrates that treatment efficacy is similar to that reported in the literature and emphasizes the need for establishing the molecular breast cancer subtypes and efforts should be made to reduce the high frequency of advanced-stage diagnoses.

Abstract
This paper presents experimental results about transport of dilute suspensions of nano-objects in silicon-glass micrometric and sub-micrometric channels. Two kinds of objects are used: solid, rigid latex beads and spherical capsule-shaped, soft polymersomes. They are tracked using fluorescence microscopy. Three aspects are studied: confinement (ratio between particle diameter and channel depth), Brownian diffusion and particle nature. The aim of this work is to understand how these different aspects affect the transport of suspensions in narrow channels and to understand the different mechanisms at play. Concerning the solid beads we observe the appearance of two regimes, one where the experimental mean velocity is close to the expected one and another where this velocity is lower. This is directly related to a competition between confinement, Brownian diffusion and advection. These two regimes are shown to be linked to the inhomogeneity of particles distribution in the channel depth, which we experimentally deduce from velocity distributions. This inhomogeneity appears during the entrance process into the sub-micrometric channels, as for hydrodynamic separation or deterministic lateral displacement. Concerning the nature of the particles we observed a shift of transition towards the second regime likely due to the relationships between shear stress and polymersomes mechanical properties which could reduce the inhomogeneity imposed by the geometry of our device.

Abstract
Adrenal cortical insufficiency secondary to destruction of the cortex by a metastatic tumor is a rare condition. Addison's disease is usually caused by an autoimmune process or by a tuberculous infection. We report a case of adrenal Insufficiency as the first clinical manifestation of a metastatic prostate carcinoma that occurred simultaneously with an active pulmonary infection by M. tuberculosis.

Abstract
Stromal-interaction molecule 1 (STIM1)-mediated store-operated Ca2+ entry (SOCE) plays a key role in mediating cardiomyocyte hypertrophy, both in vitro and in vivo. Moreover, there is growing support for the contribution of SOCE to the Ca2+ overload associated with ischemia/reperfusion injury. Therefore, STIM1 inhibition is proposed as a novel target for controlling both hypertrophy and ischemia/reperfusion-induced Ca2+ overload. Our aim was to evaluate the effect of ML9, a STIM1 inhibitor, on cardiomyocyte viability. ML9 was found to induce cell death in cultured neonatal rat cardiomyocytes. Caspase-3 activation, apoptotic index and release of the necrosis marker lactate dehydrogenase to the extracellular medium were evaluated. ML9-induced cardiomyocyte death was not associated with increased intracellular ROS or decreased ATP levels. Moreover, treatment with ML9 significantly increased levels of the autophagy marker LC3-II, without altering Beclin1 or p62 protein levels. However, treatment with ML9 followed by bafilomycin-A1 did not produce further increases in LC3-II content. Furthermore, treatment with ML9 resulted in decreased LysoTracker® Green staining. Collectively, these data suggest that ML9-induced cardiomyocyte death is triggered by a ML9-dependent disruption of autophagic flux due to lysosomal dysfunction.

Abstract
Results from a 1D setup of the European Regional Seas Ecosystem Model (ERSEM) biogeochemical model were compared with new observations collected under the UK Shelf Seas Biogeochemistry (SSB) programme to assess model performance and clarify elements of shelf-sea benthic biogeochemistry and carbon cycling. Observations from two contrasting sites (muddy and sandy) in the Celtic Sea in otherwise comparable hydrographic conditions were considered, with the focus on the benthic system. A standard model parameterisation with site-specific light and nutrient adjustments was used, along with modifications to the within-seabed diffusivity to accommodate the modelling of permeable (sandy) sediments. Differences between modelled and observed quantities of organic carbon in the bed were interpreted to suggest that a large part (>90%) of the observed benthic organic carbon is biologically relatively inactive. Evidence on the rate at which this inactive fraction is produced will constitute important information to quantify offshore carbon sequestration. Total oxygen uptake and oxic layer depths were within the range of the measured values. Modelled depth average pore water concentrations of ammonium, phosphate and silicate were typically 5-20% of observed values at the muddy site due to an underestimate of concentrations associated with the deeper sediment layers. Model agreement for these nutrients was better at the sandy site, which had lower pore water concentrations, especially deeper in the sediment. Comparison of pore water nitrate with observations had added uncertainty, as the results from process studies at the sites indicated the dominance of the anammox pathway for nitrogen removal; a pathway that is not included in the model. Macrofaunal biomasses were overestimated, although a model run with increased macrofaunal background mortality rates decreased macrofaunal biomass and improved agreement with observations. The decrease in macrofaunal biomass was compensated by an increase in meiofaunal biomass such that total oxygen demand remained within the observed range. The permeable sediment modification reproduced some of the observed behaviour of oxygen penetration depth at the sandy site. It is suggested that future development in ERSEM benthic modelling should focus on: (1) mixing and degradation rates of benthic organic matter, (2) validation of benthic faunal biomass against large scale spatial datasets, (3) incorporation of anammox in the benthic nitrogen cycle, and (4) further developments to represent permeable sediment processes.

Abstract
Expansion of white adipose tissue induce insufficient vascularization, driving hypoxia and low-grade inflammation. Resident preadipocytes are thought to be involved. We evaluated the effects of hypoxia over preadipocytes and adipocytes, to determine which cellular type impacts the most over macrophages activation. 3T3-L1 cells were either differentiated, or maintained undifferentiated. Each group was subjected to the presence or absence of chemical hypoxia (200 μM CoCl2) for 24 h. Conditioned media were used as treatment for murine RAW264.7 macrophages for 24 h. Gene expression of HIF-1α and TNF-α, and the release of several markers were assessed. It was observed that culture media from hypoxic preadipocytes induced greater expression of inflammatory markers and NO release than culture media from hypoxic adipocytes, by macrophages. Gene expression correlated closer with inflammatory markers release specially on macrophages treated with conditioned media from preadipocytes. Hence, the present work highlights the importance of preadipocytes on inflammatory conditions in vitro.

Abstract
OBJECTIVE To report the response to progestin therapy in young women with endometrial complex atypical hyperplasia (CAH) or FIGO grade 1 endometrial adenocarcinoma (FIGO 1 EAC) based on clinicopathologic features, including abnormal DNA mismatch repair (MMR) by immunohistochemistry (IHC). DESIGN Consecutive case series. SETTING Olive View-UCLA Medical Center in Sylmar, CA, USA, and Cedars-Sinai Medical Center in Los Angeles, CA, USA. POPULATION Women ≤55 years old with CAH or FIGO 1 EAC. METHODS Response to progestin therapy in 84 consecutive patients was assessed based on clinicopathologic factors, including age, body mass index (BMI), initial histology, and IHC staining for MMR proteins. MAIN OUTCOME MEASURES Rates of abnormal MMR protein expression and response to progestin therapy were determined. RESULTS Six (7%) patients had abnormal IHC staining, of whom five (83%) had FIGO 1 EAC at initial diagnosis. Following progestin treatment, none of the endometrial lesions in patients with abnormal IHC for MMR proteins had resolution of hyperplasia or malignancy, in contrast to 41 (53%) with normal staining (P = 0.028). Age ≤40 years and initial lesion (CAH versus FIGO 1 EAC) were predictors of response to progestin; BMI was not. CONCLUSIONS In this cohort, 7% of women ≤55 years of age with CAH or FIGO 1 EAC had loss of MMR proteins by IHC. These patients had a higher incidence of invasive cancer and a lower incidence of resolution with progestin therapy. TWEETABLE ABSTRACT Abnormal MMR protein expression predicts poor response to progestins in young women with CAH or FIGO 1 EAC.

Abstract
After a burn lesion, Acute Respiratory Distress Syndrome (ARDS) may occur via direct lung injury due to inhaled smoke and fumes or mediated by the inflammatory response associated with the burn or its infectious complications. The aim of the present study is to assess the epidemiologic profile of ARDS in adult burn patients admitted to intensive care in a burn unit at a university hospital. A prospective cohort study was performed from January to December 2012. Demographic and diagnostic data, prognostic scores, etiology and data on the extent and depth of burns were collected. Data related to risk factors for ARDS and death were also recorded. A total of 85 patients were included in the study. Patients were aged 41.7 (SD = 15.7) years old; 71.8% were male and the mean total body surface area burned was 28.3% (SD = 19.1%); 35.3% presented inhalation injuries. Invasive ventilatory support was required in 44 ICU inpatients (51.8%). ARDS was diagnosed in 38.6% of patients under invasive mechanical ventilation. In multivariate analysis, the presence of inhalation injuries was a risk factor for ARDS (OR = 9.75; CI 95% 2.79 - 33.95; P < 0.001). ARDS is a common complication in burn patients admitted to specialized intensive care units. Inhalation injuries were an independent risk factor for ARDS. Mortality rate observed in the study patients was high and associated with ARDS diagnosis.

Abstract
BACKGROUND F-flurodeoxyglucose positron emission tomography (FDG-PET) have been claimed to be an important prognostic tool in different malignancies. However, its predictive prognostic value on pancreatic neuroendocrine tumors (PNETs) is still under investigation. AIM We study the prognostic impact of FDG-PET scan in neuroendocrine pancreatic tumors. METHODOLOGY Between 2007 and 2012, 26 patients with no metastastatic histologically confirmed PNETs (mean age: 57 years) were examined with FDG-PET. We studied its captation in relation with the well established hystopathological prognostic markers assessed in the tumoral resected specimen according to the WHO 2004 and ENETS/WHO 2010 classification. RESULTS FDG-PET captation was positive in 17 cases (65.4%). The median follow-up period was 34.4 months and recurrences occurred in 4 cases (15.4%). We found a significant correlation between this captation and Ki 67 index (p = 0.032), mitotic index (p = 0.002), tumor grade (p = 0.017) and tumor size (p = 0.01). CONCLUSIONS FDG-PET provides a good prognostic value for PNETs. Present results must be further validated with larger sample studies.

Abstract
Interferon alpha is a cytokine with antiviral and antineoplastic action, which is commonly used for treatment of Hepatitis C and B, malignant melanoma, Kaposi's sarcoma, kidney cancer and certain hematologic diseases. It is well-known some of its neuropsychiatric symptoms such as depressive symptoms, cognitive impairment, chronic fatigue, dysphoria and anxiety, but there are also other less common like mania, psychotic symptoms and suicide risk that have been reported. These symptoms interfere in the quality of life very significantly, which at the end can affect treatment adherence.We report a case of a 33-year-old man who was taken to the emergency department by his family referring nervousness, irritability, verbose, and insomnia during the last 5 days. The patient had not psychiatric history. He was diagnosed with a malignant melanoma stage III A a year ago which required to start interferon alpha treatment.Patient and family tell that symptoms began after forgetting last interferon dose. In the psychopathology exploration, we could observe mood lability, delusion ideas of prosecution, which includes his entire family and autorreferentiality. In the emergency room the blood test, urine drug test and CT were normal.During the admission, and in collaboration with the Oncology service, it was agreed the reintroduction and maintenance of interferon combined with olanzapine up to 30 mg/day and clonazepam up to 6 mg/day, which resulted in the resolution of symptoms in two weeks.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND African Americans are reported to be more sensitive to pain than European Americans. Pain sensitivity has been shown to be genetically linked in animal models and is likely to be in humans. METHODS Exactly, 11,239 self-identified African American post-menopausal women enrolled in the Women's Health Initiative had percentage African ancestry determined by ancestry informative markers, "Pain Construct" measurements and covariate information. They answered five questions about specific types and location of pain, such as joint, neck, low back, headache and urinary. They also answered two questions which were used to derive a "Pain Construct", a measure of general pain scored on a scale of 1-100. Associations were tested in linear regression models adjusting for age, self-reported medical conditions, neighbourhood socio-economic status, education and depression. RESULTS In the unadjusted model of the five specific types of pain measures, greater pain perception was associated with a higher proportion of African ancestry. However, some of the specific types of pain measures were no longer associated with African ancestry after adjustment for other study covariates. The Pain Construct was statistically significantly associated with African ancestry in both the unadjusted [β = -0.132, 95% confidence interval (CI) = -099 to -0.164; r = -0.075, 95% CI -0.056 to -0.093] and the adjusted models (β = -0.069 95% CI = -0.04 to -0.10). CONCLUSIONS Greater African ancestry was associated with higher levels of self-reported pain, although this accounted for only a minor fraction of the overall variation in the Pain Construct.
