THU0582 Prognostic Factors of Macrophage Activation Syndrome in Adults: Analysis of 40 Cases in 2 Tertiary Referral Centers

2016

Background Macrophage activation syndrome (MAS) is a rare, life-threatening disease in which early diagnosis and aggressive therapeutic strategy may improve the outcome [1]. Due to its rarity, epidemiologic data are still lacking. Hyperferritinemia is frequently associated with MAS and might modulate the cytokines storm the latter contributing to the development of multi-organ failure [2]. Objectives In the current study, we aimed to investigate clinical data, treatments, and outcome of adult MAS patients secondary to autoimmune rheumatic disease. Methods We retrospectively investigated clinical data, treatments, and outcome of 40 adult MAS patients secondary to autoimmune rheumatic disease…

Social deprivation and 1‐year survival after stroke: a prospective cohort study

2020

BACKGROUND Social deprivation may have a deleterious influence on post-stroke outcomes, but available data in the literature are mixed. AIM The aim of this cohort study was to evaluate the impact of social deprivation on 1-year survival in patients with first-ever stroke. METHODS Social deprivation was assessed at individual level with the EPICES score, a validated multidimensional questionnaire, in 1312 patients with ischemic stroke and 228 patients with spontaneous intracerebral hemorrhage, who were prospectively enrolled in six French study centers. Baseline characteristics including stroke severity and pre-stroke functional status were collected. Multivariable Cox models were generated …

Compliance with patient-reported outcome assessment in glioma patients: predictors for drop out

2017

Abstract Background Patient-reported outcomes are of high importance in clinical neuro-oncology. However, assessment is still suboptimal. We aimed at exploring factors associated with the probability for a) drop out of study and b) death during follow-up. Methods Patients were assessed twice during follow-up visits scheduled within 3 to 5 months of each other by using 3 validated patient-reported outcome measures (t1: first assessment, t2: second assessment). As “death” was seen as a competing risk for drop out, univariate competing risk Cox regression models were applied to explore factors associated with dropping out (age, gender, WHO grade, living situation, recurrent surgery, Karnofsky …

IntroductionWork-life conflicts (WLC) may impact health, but few studies prospectively consider the impact of WLC on objective outcomes such as cardiovascular disease. Using data from the Gutenberg Health Study (GHS), we examined if WLC at baseline was associated with an increased five-year incidence of cardiovascular events (myocardial infarct, stroke, atrial fibrillation, peripheral artery disease, coronary artery disease, chronic heart failure, sudden cardiac death). We also considered if WLC was associated with incident hypertension and arterial stiffness and if the effects of WLC on cardiovascular health differ for men and women.MethodsA working subsample of the 15,010 GHS cohort parti…

Dynamic angiopoietin-2 assessment predicts survival and chronic course in hospitalized patients with COVID-19

2021

Key Points Three-day change in angiopoietin-2 levels predicts COVID-19 in-hospital mortality, whereas the 10-day trend is associated with chronic lung disability. Angiopoietin-2 may play an important pathogenic role in patients with COVID-19, and it could be a target for new treatments.

GEMS, a GEnetic and Metabolic Staging predicting the outcome of non-alcoholic fatty liver disease

2021

Background and Aim: Non-alcoholic fatty liver disease(NAFLD) is an emergent cause of liver-related events(LRE). We have assessed the ability of a composite score based on clinical features, metabolic comorbidities and genetic background, to predict LRE. Methods: 546 consecutive patients with NAFLD were recruited and stratified according to FIB-4(low risk <1.3;intermedium-high risk ≥1.3). LRE were defined as occurrence of HCC or hepatic decompensation. Cox regression multivariate analysis was used to identify baseline variables associated with LRE. Results: Over a median follow-up of 73.8 months, 58 patients experienced LRE(only 1 in the cohort of patients with FIB-4 65 years(HR 17.96), plat…

1088 Minimally-invasive pelvic exenteration: a survival analysis

2021

Minimally-invasive pelvic exenteration: a survival analysis. Introduction/Background* Pelvic exenteration for recurrent and persistent gynecological malignancies is traditionally performed with open approach (OA). Nevertheless, reports on the use of minimally-invasive surgical (MIS) approach to pelvic exenteration have been published with promising results in terms of peri-operative morbidity. However, oncological safety of this approach has been poorly investigated. The aim of the present study was to assess the disease-free survival (DFS) and overall survival (OS) of patients undergoing minimally-invasive pelvic exenteration. Methodology All patients undergoing pelvic exenteration for gyn…

Clinical utility of antigen carbohydrate 125 for planning the optimal length of stay in acute heart failure.

2021

BACKGROUND: The optimal length of stay (LOS) in patients hospitalized for acute heart failure (AHF) remains controversial. Plasma antigen carbohydrate 125 (CA125) has emerged as a reliable proxy of congestion. We aimed to evaluate whether there is a differential impact of LOS on the risk of 6-month AHF readmission across CA125 levels. METHODS: This is a retrospective study that included 1,387 patients discharged for AHF in two third-level centers. CA125 was measured 48±24h after admission. The association between CA125 and LOS with the risk of subsequent AHF readmission at 6 months was analyzed by Cox regression analysis accounting for death as a competing event. RESULTS: The median (IQR) a…

Prognostic factors on surgically and non-surgically treated oral squamous cell carcinoma: Advances in survival in fifteen years of follow up

2021

Background Retrospectively to evaluate the influence of radiochemotherapy (RCT) in the treatment of surgically and non-surgically treated Oral Squamous Cell Carcinoma (OSCC). Material and Methods We analysed 934 patients treated in Hospital Haroldo Juacaba (2000-2014; 15 years of study) by extraction of data type of cancer, localization of tumour, sex, age, race, education level, risk factors (smoking and alcohol use), year of diagnosis, TNM stage, therapeutic approach, health system used (public or private) and overall survival (OS). Surgically and non-surgically treated OSCC were compared by chi-square and Fisher's exact tests, and their prognostic factors were analysed by log-rank Mantel…

246 Survival of elderly patients with endometrial cancer – predicted by preoperative G-8 geriatric screening tool

2021

Introduction/Background* We evaluated the prognostic impact of various global health assessment tools in accordance to conventional prognostic factors in patients with endometrial cancer (EC) older than 60 years. Methodology G-8 geriatric screening tool (G-8 geriatric score), Lee Schonberg prognostic index (Lee-Index), Charlson Comorbidity Index (CCI) and American Society of Anesthesiologists (ASA-PS) – Physical Status System were retrospectively determined in a consecutive cohort of elderly patients with EC. Univariate and multivariate Cox regression analyses and Kaplan-Meier method were performed to determine the impact of the global health assessment tools on progression free survival (P…
