Comparison of resection and transarterial chemoembolisation in the treatment of advanced intrahepatic cholangiocarcinoma--a single-center experience.

2012

Abstract Aims The aim of this study is to evaluate factors associated with the outcome after surgical resection and to compare the efficacy of surgery to transarterial chemoembolisation (TACE) in patients with advanced intrahepatic cholangiocarcinoma (IHC). Materials and methods 273 patients with IHC treated in our department between 1997 and 2012 were included in our study. Patients were divided according to therapy into surgical ( n  = 130), TACE ( n  = 32), and systemic chemotherapy/best supportive care ( n  = 111) groups. Clinicopathological characteristics and survival were reviewed retrospectively. Results The 1-, 3-, and 5-year survival rates in patients after surgical resection were…

The combination of liver stiffness measurement and NAFLD fibrosis score improves the noninvasive diagnostic accuracy for severe liver fibrosis in pat…

2014

Background & Aims The accuracy of noninvasive tools for the diagnosis of severe fibrosis in patients with nonalcoholic fatty liver disease(NAFLD) in clinical practice is still limited. We aimed at assessing the diagnostic performance of combined noninvasive tools in two independent cohorts of Italian NAFLD patients. Methods We analysed data from 321 Italian patients(179 Sicilian-training cohort, and 142 northern Italy-validation cohort) with an histological diagnosis of NAFLD. Severe fibrosis was defined as fibrosis ≥ F3 according to Kleiner classification. The APRI, AST/ALT, BARD, FIB-4, and NFS scores were calculated according to published algorithms. Liver stiffness measurement(LSM) was …

Mortality risk according to different clinical characteristics of first episode of liver decompensation in cirrhotic patients: a nationwide, prospect…

2013

Abstract OBJECTIVES: The occurrence of decompensation marks a crucial turning point in the course of cirrhosis. The purpose of this study was to assess the risk of mortality according to the clinical characteristics of first decompensation, considering also the impact of acute-on-chronic liver failure (AoCLF). METHODS: We conducted a prospective nationwide inception cohort study in Italy. Decompensation was defined by the presence of ascites, either overt or detected by ultrasonography (UD), gastroesophageal variceal bleeding (GEVB), and hepatic encephalopathy (HE). AoCLF was defined according to the Asian Pacific Association for the Study of the Liver criteria. Multivariable Cox proportion…

Predicting Mortality Risk in Patients With Compensated HCV-Induced Cirrhosis: A Long-Term Prospective Study

2009

OBJECTIVES: The identification of prognostic factors associated with mortality is crucial in any clinical setting. METHODS: We enrolled in a prospective study 352 patients with compensated hepatitis C virus (HCV)-induced cirrhosis, consecutively observed between 1989 and 1992. At entry, patients underwent upper endoscopy to detect esophageal varices, and were then surveilled by serial clinical and ultrasonographic examination. The model for end-stage liver disease (MELD) score was calculated with information collected at enrollment. Baseline predictors and intercurrent events associated with mortality were assessed using the Cox regression model. RESULTS: During a median follow-up of 14.4 y…

Predictors of mortality in patients under treatment for chronic hepatitis B in Ethiopia: a prospective cohort study

2019

Abstract Background Antiviral treatment for chronic hepatitis B (CHB) is largely unavailable in sub-Saharan Africa; hence, little is known about the prognosis after initiating treatment in African CHB patients. In this study we aimed to assess predictors of mortality in one of the largest CHB cohorts in sub-Saharan Africa. Methods Two-hundred-and-seventy-six CHB patients who started treatment with tenofovir disoproxil fumarate at a public hospital in Ethiopia between March 18, 2015, and August 1, 2017, were included in this analysis. Patients were followed up until October 1, 2017, and deaths were ascertained through hospital records and telephone interview with relatives. Decompensated cir…

Harmonization of real-world studies in multiple sclerosis: Retrospective analysis from the rirems group

2020

Background: Worldwide multiple sclerosis (MS) centers have coordinated their efforts to use data acquired in clinical practice for real-world observational studies. In this retrospective study, we aim to harmonize outcome measures, and to evaluate their heterogeneity within the Rising Italian Researchers in MS (RIReMS) study group. Methods: RIReMS members filled in a structured questionnaire evaluating the use of different outcome measures in clinical practice. Thereafter, thirty-four already-published papers from RIReMS centers were used for heterogeneity analyses, using the DerSimonian and Laird random-effects method to compute the between-study variance (τ2). Results: Based on questionna…

The physician-patient relationship before cancer treatment: a prospective longitudinal study.

2003

Abstract Objectives . To evaluate quality of life before surgery for genital cancer to determine risk factors that might influence the physician–patient relationship. Methods . From 1993 until 2003, 129 women with cervical cancer entered this prospective study. Patients were contacted 1 to 5 days before surgery by a psychologist or psychotherapeutically trained physician on the surgical ward. The semistructured interview included questions on the patient's psychosocial well-being according to criteria of the biographic interview technique. The preoperative anxiety level was evaluated by the STAI and quality of life by the Cancer Rehabilitation Evaluation System (CARES) and EORTC questionnai…

Are Asthmatics Enrolled in Randomized Trials Representative of Real-Life Outpatients?

2014

<b><i>Background/Objective:</i></b> This study was aimed at exploring to what extent populations enrolled in randomized controlled trials (RCTs) of inhalation combination treatment for mild/moderate asthma in adults are fully representative of ‘real-life' populations. The following is a retrospective analysis of the clinical records of outpatient subjects with an ascertained diagnosis of asthma. <b><i>Methods:</i></b> A retrospective analysis was performed. Stable conditions, such as smoking habit and chronic diseases other than asthma, were identified as exclusion criteria for RCTs. The selected criteria were then applied to asthmatic outpati…

Physical injury and depression in six low- and middle-income countries: A nationally representative study.

2019

BACKGROUND: Studies on the association between physical injury and depression in low- and middle-income countries (LMICs) are scarce. Therefore, our goal was to analyze the association between physical injury and depression using nationally representative data from six LMICs. METHODS: Cross-sectional data from the Study on Global Ageing and Adult Health (SAGE) survey (2007-2010) were analyzed (N?=?42,489). Questions based on the World Mental Health Survey version of the Composite International Diagnostic Interview were used for the endorsement of past 12-month DSM-IV depression. Any injury in our analysis referred to having experienced traffic injury or other injury in the past 12 months. M…
