Inguinal hernioplasty in patients with cirrhosis and ascites: what preventive measures are needed for a safe procedure?

2019

Inguinal hernioplasty in patients with LC and ascites has been long discouraged for the incidence of postoperative complications. The aim is to evaluate the appropriateness of this elective surgical procedure in patients with LC and ascites.Thirty consecutive LC patients with ascites and affected by inguinal hernia (LC group), who underwent elective open inguinal hernioplasty with mesh placement, have been matched with the same number of patients non-LC (non-LC group) who underwent the same surgical procedure in the same period of time. All patients in LC group received a careful hepatological assessment and were classified according to the etiology of LC and to the Child's class. Patients …

Assessing inter- and intra-individual cognitive variability in patients at risk for cognitive impairment: the case of minimal hepatic encephalopathy

2014

Recent evidence reveals that inter- and intra-individual variability significantly affects cognitive performance in a number of neuropsychological pathologies. We applied a flexible family of statistical models to elucidate the contribution of inter- and intra-individual variables on cognitive functioning in healthy volunteers and patients at risk for hepatic encephalopathy (HE). Sixty-five volunteers (32 patients with cirrhosis and 33 healthy volunteers) were assessed by means of the Inhibitory Control Task (ICT). A Generalized Additive Model for Location, Scale and Shape (GAMLSS) was fitted for jointly modeling the mean and the intra-variability of Reaction Times (RTs) as a function of so…

Proton pump inhibitors increase risk of bone fractures in men with cirrhosis: a population-based study

2020

Bone fractures are a frequent complication in patients with cirrhosis. Proton pump inhibitors (PPIs) are among the most frequently prescribed medications and may impair bone quality and quantity.To investigate whether PPI use predisposes patients with cirrhosis to bone fractures.We performed a population-based case-control study exploring a sample of patients with cirrhosis derived from the Disease Analyzer database. In total, 1795 cirrhotic patients with fractures were compared to 10 235 cirrhotic patients without fractures. PPI use overall and the cumulative PPI dose 5 years prior to the index date were analysed. To estimate the association between PPI use and fractures, logistic regressi…

Deferiprone versus deferoxamine in patients with thalassemia major: a randomized clinical trial.

2002

Deferiprone has been suggested as an effective oral chelation therapy for thalassemia major. To assess its clinical efficacy, we compared deferiprone with deferoxamine in a large multicenter randomized clinical trial. One-hundred forty-four consecutive patients with thalassemia major and serum ferritin between 1500 and 3000 ng/ml were randomly assigned to deferiprone (75 mg/kg/day) (n = 71) or deferoxamine (50 mg/kg/day) (n = 73) for 1 year. The main measure of efficacy was the reduction of serum ferritin. Liver and heart iron contents were assessed by magnetic resonance. Liver iron content and fibrosis stage variations were assessed on liver biopsy by the Ishak score in all patients willin…

Increased protein kinase A regulatory subunit content and cGMP binding in erythrocyte membranes in liver cirrhosis

2003

Abstract Background/Aims : Patients with liver disease show increased plasma cGMP and decreased intracellular cGMP in lymphocytes. The initial aim of this work was to assess whether decreased intracellular cGMP and increased plasma cGMP may be due to increased ATP-dependent release of cGMP from cells. The results obtained led to a new aim: to identify and quantify a protein responsible for the increased cGMP binding found in erythrocyte membranes from patients with liver disease. Methods : ATP-dependent cGMP transport was determined in inside-out vesicles from erythrocyte membranes. cGMP-binding proteins were isolated from the membranes and identified by MALDI-TOF peptide mass fingerprint. …

Serum nitrotyrosine and psychometric tests as indicators of impaired fitness to drive in cirrhotic patients with minimal hepatic encephalopathy

2013

BACKGROUND & AIMS: Cirrhotic patients with minimal hepatic encephalopathy (MHE) show impaired driving ability and increased vehicle accidents. The neurological deficits contributing to impair driving and the underlying mechanisms are poorly understood. Early detection of driving impairment would help to reduce traffic accidents in MHE patients. It would be therefore useful to have psychometric or biochemical parameters reflecting driving impairment. The aims of this work were as follows: (i) to shed light on the neurological deficits contributing to impair driving; (ii) to assess whether some psychometric test or biochemical parameter is a good indicator of driving impairment. METHODS: We a…

Factors That Contribute or Impede the Physical Health Recovery of Women Exposed to Intimate Partner Violence: A Longitudinal Study

2012

Abstract Background Several cross-sectional studies have demonstrated the negative impact that intimate partner violence (IPV) has on the physical health of women. However, longitudinal studies are needed to establish the time course of this effect. This study assessed the physical health course of female IPV victims and established the factors that enhance or impede their recovery. Methods Women ( n  = 91) who participated in a previous cross-sectional study (T-1) and were either victims of physical/psychological IPV ( n  = 33) or psychological IPV ( n  = 23) were evaluated 3 years later (T-2). A control group of women ( n  = 35) was included for comparison. Structured interviews provided …

Investigating the role of self‐control beliefs in predicting exercise behaviour: A longitudinal study

2021

Background: Engaging in exercise behaviour regularly requires a repeated investment of resources to reap the health benefits. An individual’s self-control resources, when performing a behaviour can be perceived as being recharged or depleted. The investigation on how self-control beliefs resources predict exercise behaviour is very limited in the literature. The purpose of this study was to understand how self-control beliefs predict exercise behaviour across time in a physical activity model. Methods: Participants (N = 161) were a sample of adults recruited across twelve gyms and recreation centres in a large city. Participants completed surveys across five months. Data were analysed using…

Intraoperative positive end-expiratory pressure and postoperative pulmonary complications: a patient-level meta-analysis of three randomised clinical…

2022

BACKGROUND: High intraoperative PEEP with recruitment manoeuvres may improve perioperative outcomes. We re-examined this question by conducting a patient-level meta-analysis of three clinical trials in adult patients at increased risk for postoperative pulmonary complications who underwent non-cardiothoracic and non-neurological surgery. METHODS: The three trials enrolled patients at 128 hospitals in 24 countries from February 2011 to February 2018. All patients received volume-controlled ventilation with low tidal volume. Analyses were performed using one-stage, two-level, mixed modelling (site as a random effect; trial as a fixed effect). The primary outcome was a composite of postoperati…

Early Lung Function Abnormalities in Acromegaly.

2014

BACKGROUND: Acromegaly is an insidious disorder caused by a pituitary growth hormone (GH)-secreting adenoma resulting in high circulating levels of GH and insulin-like growth factor I (IGF-I). Respiratory disorders are common complications in acromegaly, and can severely impact on quality of life, eventually affecting mortality. OBJECTIVES: The present study aimed to explore structural and functional lung alterations of acromegalic subjects. METHODS: We enrolled 10 consecutive patients (M/F: 5/5) affected by acromegaly. In all patients, magnetic resonance imaging (MRI) revealed the presence of pituitary tumor. All patients underwent clinical, lung functional, biological, and radiological as…
