Prediction of serious complications in patients with pulmonary thromboembolism and solid cancer: Validation of the EPIPHANY Index in a prospective cohort of patients from the PERSEO study.

Introduction: There is currently no validated score capable of classifying cancer-associated pulmonary embolism (PE) in its full spectrum of severity. This study has validated the EPIPHANY Index, a new tool to predict serious complications in cancer patients with suspected or unsuspected PE.

Method: The PERSEO Study prospectively recruited individuals with PE and active cancer or receiving antineoplastic therapy from 22 Spanish hospitals.

Lower limb cutaneous melanoma surgery: location matters.

The anatomical location of cutaneous melanoma is a relevant independent prognostic factor in melanoma. The aim of the study is to know the prognosis of lower limb cutaneous melanoma related to their location within the limb, regardless of the histological type, and if there are any other influencing variables. A real-world data observational study was developed.

Coloured hybrid materials: exploiting an emergent surface property of fluorinated AlO containing anthocyanins and betacyanins.

Two fluorinated γ-AlO series were synthesized by a sol-gel method with two solvents (2-propanol and 2-butanol), two aluminium sources (ATB and ATP) and one fluorine source (NaAlF). The resulting inorganic matrixes were evaluated to characterize aluminium and fluorine species ([AlO], [AlO], [AlO], [AlF], [AlF] and [AlF]) by powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Al magic angle spinning nuclear magnetic resonance (Al MAS-NMR) and infrared spectroscopy (IR-ATR). BET and BJH analyses using the nitrogen isotherms of these materials allowed identifying a clear trend in some textural parameters such as specific surface area and fluorine content.

Complete remission of stage IV sinonasal small cell neuroendocrine carcinoma: A case report.

Sinonasal small cell carcinoma (SmCC) is a rare type of neoplasm. The current case report describes the case of a 30-year-old male patient with stage IV SmCC who underwent concurrent radiotherapy (RT) plus etoposide-cisplatin treatment. Positron emission tomography (PET)/computed tomography (CT) and fibroscopy examination showed complete remission at 3 months post-treatment.

A Source of Systematic Errors in the Determination of Critical Micelle Concentration and Micellization Enthalpy by Graphical Methods in Isothermal Titration Calorimetry.

Isothermal titration calorimetry is frequently employed to determine the critical micelle concentration and the micellization enthalpy of surfactants in terms of geometrical characteristics of the titration curves. Previously we have shown theoretically that even for an infinitesimal injection, the heat per titrant mol depends on the stock solution concentration. In this work, we explore experimentally the influence of the stock solution concentration on the geometrical characteristics of the titration curve and its effect in determining the critical micelle concentration and the micellization enthalpy of surfactants.
