Heart rate variability changes at 2400 m altitude predicts acute mountain sickness on further ascent at 3000-4300 m altitudes
2012
Objective: If the body fails to acclimatize at high altitude, acute mountain sickness (AMS) may result. For the early detection of AMS, changes in cardiac autonomic function measured by heart rate variability (HRV) may be more sensitive than clinical symptoms alone. The purpose of this study was to ascertain if the changes in HRV during ascent are related to AMS. Methods: We followed Lake Louise Score (LLS), arterial oxygen saturation at rest (R-SpO2) and exercise (Ex-SpO2) and HRV parameters daily in 36 different healthy climbers ascending from 2400 m to 6300 m altitudes during five different expeditions. Results: After an ascent to 2400 m, root mean square successive differences, high-fre…
Label-free piezoelectric biosensor for prognosis and diagnosis of Systemic Lupus Erythematosus
2017
[EN] An autoantigen piezoelectric sensor to quantify specific circulating autoantibodies in human serum is developed. The sensor consisted on a quartz crystal microbalance with dissipation monitoring (QCM-D) where TRIM21 and TROVE2 autoantigens were covalently immobilized, allowing the selective determination of autoantibodies for diagnosis and prognosis of Systemic Lupus Erythematosus (SLE). The sensitivity of the biosensor, measured as IC50 value, was 1.51 U/mL and 0.32 U/mL, for anti-TRIM21 and anti-TROVE2 circulating autoantibodies, respectively. The sensor is also able to establish a structural interaction fingerprint pattern or profile of circulating autoantibodies, what allows scorin…
Diagnostic yield of a one sample immunochemical test at different cut-off values in an organised screening programme for colorectal cancer
2013
Abstract Background Quantitative immunochemical faecal occult blood tests have become the recommended tests for colorectal cancer screening. The aim of this study was to complete our knowledge on the performance of one of the quantitative immunochemical tests available, FOB-Gold, and to propose a possible strategy for an organised screening programme. Patients and methods Within the French organised screening programme, 23,231 average-risk individuals, aged 50–74 performed both a 3-day Hemoccult test and a 1-day FOB-Gold test. Performances of the immunochemical test were evaluated at different cut-off levels. Results The positivity rate for the Hemoccult was 2.1% and for the FOB-Gold varied…
Educational needs in gastrointestinal cancer: a consensus position paper from the ESMO Gastrointestinal Cancer Faculty
2019
Gastrointestinal (GI) cancers are common in all parts of the world. Effective prevention and early detection of GI cancers are not universally implemented. Therefore, it must be anticipated that the incidence and the mortality of GI cancers will remain high within the next decades. The European Society for Medical Oncology (ESMO) Gastrointestinal Cancer Faculty aims to increase the skills of medical oncologists and other disciplines involved in treating GI malignancies. We aimed to increase the survival chances for patients with GI cancers, augment their quality of life and enable successful return to normal social and professional life during the period of survivorship. ESMO also aims to d…
EASL HCC summit: liver cancer management
2014
EASL HCC Summit, Geneva, Switzerland, 13–16 February 2014 The European Association for the Study of the Liver (EASL) organized the 2014 EASL HCC Summit in Geneva, Switzerland. We discuss here the most interesting and provocative contents from the clinical program of the summit. The objective of this segment was to provide an in-depth review on the different management issues related to early detection, diagnosis and treatment of hepatocellular carcinoma, and, in addition, to highlight the ways of dealing with such an important and rapidly involving field.
Does endoscopic follow-up improve the outcome of patients with benign gastric ulcers and gastric cancer?
1992
This study investigated whether an endoscopic surveillance program for patients with "benign" gastric ulcers and gastric cancer leads to early detection of neoplasms and improves survival. The clinical course of all patients diagnosed between 1977 and 1986 as having either gastric ulcers or gastric cancer was followed for a minimum of 3 years. Of 597 patients with initially benign gastric ulcers, 452 (76%) returned for the recommended endoscopic follow-up examinations. In eight patients (1.8%), repeated biopsies disclosed malignant neoplasms; four of these patients (0.9%) had become asymptomatic. Survival curves were nearly identical in patients who complied and those who did not. Of 241 pa…
Early detection of myocardial damage: A multimodality approach
2019
Cardiovascular diseases are possible complications of antineoplastic treatment and may lead to premature morbidity and mortality among cancer survivors. A symptom-based follow-up is ineffective, and there are growing evidences that early detection of myocardial damage in patients treated with antineoplastic drugs is the key point to prevent the occurrence of damage and improve the prognosis of these patients. Different techniques have been proposed to monitor cardiac function in oncologic patients such as cardiac imaging (echocardiography, nuclear imaging, and cardiac magnetic resonance) and biomarkers (troponin and natriuretic peptides). The European Association of Cardiovascular Imaging/A…
Left atrial strain and left atrial stiffness for early detection of cardiotoxicity in cancer patients
2021
Abstract Background Anti-cancer drugs can cause cardiovascular complications. Left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) are usually used to identify clinical and subclinical cardiotoxicity. Purpose The aim of our study was to assess the addictional role of left atrial reservoir strain (LAS-S) and left atrial stiffness (LASI – the ratio of E/e' to LAS-S) in identifying patients at higher risk of cardiotoxicity. Methods 102 breast cancer patients (median age 53±9.5 years), without cardiovascular diseases, were enrolled before starting chemotherapy. Electrocardiogram and transthoracic echocardiogram (conventional measurements based on EACVI recommendations;…
Cardiovascular Damage in Clinical Trials
2018
The Cardio-oncology field has grown considerably in the last two decades. The remarkable increase in the number of molecules used in oncology has brought with it a huge set of cardiovascular adverse events. For this reason, it is necessary to intervene on the early stages of drug development. This is what the Food and Drug Administration aims to do. This purpose can be achieved through a more careful analysis of the adverse event, development of guidelines, and identification of objective parameters that could guide the researcher in defining precisely the adverse event. It is also necessary to use additional methods not yet used in clinical trials that can allow an early detection of adver…
[Diagnostic performance of surface electrocardiogram in early detection of chagasic cardiomyopathy].
2013
Contrast-enhanced cardiac magnetic resonance imaging (CMR) allows early detection of myocardial involvement by Trypanosoma cruzi infection. The aim of our study was to assess the diagnostic performance of the surface electrocardiogram (ECG) in the early detection of Chagas' cardiomyopathy (CCM) compared with CMR.We included 43 asymptomatic patients (30 women, 42 ± 9.8 years), diagnosed of Chagas disease. The sample was divided into 2 groups according to the presence (n=17) or absence (n=26) of electrocardiographic abnormalities. All patients underwent CMR and late gadolinium enhancement (LGE) was used as a marker of early myocardial involvement.Six (14%) patients had a LGE significantly hig…
