Postoperative complications and waiting time for surgical intervention after radiologically guided drainage of intra-abdominal abscess in patients wi…

2021

Abstract Background In patients with active Crohn’s disease (CD), treatment of intra-abdominal abscess usually comprises antibiotics and radiologically guided percutaneous drainage (PD) preceding surgery. The aim of this study was to investigate the risk of postoperative complications and identify the optimal time interval for surgical intervention after PD. Methods A multicentre, international, retrospective cohort study was carried out. Details of patients with diagnosis of CD who underwent ultrasonography- or CT-guided PD were retrieved from hospital records using international classification of disease (ICD-10) diagnosis code for CD combined with procedure code for PD. Clinical variable…

Social isolation and depression predict 12-month outcomes in the "waiting for a new heart study".

2009

Identification of modifiable psychosocial characteristics related to survival of heart transplant (HTx) candidates is needed to prevent clinical deterioration and improve prognosis.A multi-site, prospective study was conducted with 318 HTx candidates (18% female, 82% male; 53 +/- 11 years of age) newly listed at 17 hospitals in Germany and Austria. Baseline demographic and psychosocial characteristics were assessed by questionnaires. Indicators of disease severity (Heart Failure Survival Score, creatinine, cardiac index) and 12-month outcomes (death, high-urgency HTx, elective HTx, de-listing due to deterioration or improvement) were provided by Eurotransplant.By 12 months, 33 patients died…

Timing of Renal Replacement Therapy for Severe Acute Kidney Injury in Critically Ill Patients

2019

Acute kidney injury (AKI) affects many ICU patients and is responsible for increased morbidity and mortality. Although lifesaving in many situations, renal replacement therapy (RRT) may be associated with complications, and the appropriate timing of its initiation is still the subject of intense debate. An early initiation strategy can prevent some metabolic complications, whereas a delayed one may allow for renal function recovery in some patients without need for this costly and potentially dangerous technique. For years, most of the knowledge on this issue stemmed from observational studies or small randomized controlled trials. Recent randomized controlled trials have indicated that a w…

Systemic Thrombolytic Therapy for Acute Pulmonary Embolism: Who Is a Candidate?

2017

Pulmonary embolism (PE) is a major cause of both acute and long-term morbidity for a large number of patients worldwide, and massive PE is frequently fatal. Right ventricular (RV) dysfunction is a key determinant of prognosis in the acute phase of PE. Patients with clinically overt RV failure, that is, with cardiogenic shock or persistent hypotension at presentation (acute high-risk PE), are clearly in need of immediate reperfusion treatment with systemic thrombolysis or, alternatively, surgical or catheter-directed techniques. On the other hand, within the large group of patients presenting without hemodynamic instability, the bleeding risk of full-dose intravenous thrombolytic treatment h…

L’attesa come condizione esistenziale: SAID Landschaften einer fernen Mutter, 2001 e Marjane Satrapi Persepolis, 2007

2018

In this paper the author intends to analyze the concept of ‘waiting time’ that, in a different way, also seen the substantial artistic diversity, is present in the film Persepolis by Marjane Satrapi, 2007, based on the namesake graphic novel written by the French-Iranian director in 2000, and in the novel Landschaften einer fernen Mutter written by the German-Iranian author SAID, 2001. The analysis that is conducted here wants to investigate how both, in the film and in the literary work, the ‘waiting time’ for the exile takes on totally personal connotations, becoming also not only part of the life of Satrapi and SAID, but above all a state of mind.

Delisting of liver transplant candidates with chronic hepatitis C after viral eradication: A European study

2016

Background & Aims: All oral direct acting antivirals (DAA) have been shown to improve the liver function of patients with decompensated cirrhosis but it is presently unknown whether this clinical improvement may lead to the delisting of some patients. The aim of this study was to assess if and which patients can be first inactivated due to clinically improvement and subsequently delisted in a real life setting. Methods: 103 consecutive listed patients without hepatocellular carcinoma were treated with different DAA combinations in 11 European centres between February 2014 and February 2015. Results: The cumulative incidence of inactivated and delisted patients by competing risk analysis…

Multimodal approaches to the treatment of hepatocellular carcinoma.

2008

The prevalence of hepatocellular carcinoma in Europe and the US is increasing and is currently the leading cause of death in patients with cirrhosis. Surveillance programs for patients with cirrhosis aim to detect tumors at an early stage, when the greatest therapeutic benefits can be achieved. Curative treatments for early-stage tumors include liver transplantation, resection and percutaneous ablation. Transarterial chemoembolization (TACE) and sorafenib can improve survival for patients with intermediate and advanced tumors, respectively. In clinical practice, combination therapies are often used, despite limited evidence to support this approach from randomized controlled trials. Combina…

Analysis of the renal transplant waiting list in the País Valencià (Spain).

2005

In this paper we analyse the renal transplant waiting list of the Pais Valencia in Spain, using Queueing theory. The customers of this queue are patients with end-stage renal failure waiting for a kidney transplant. We set up a simplified model to represent the flow of the customers through the system, and perform Bayesian inference to estimate parameters in the model. Finally, we consider several scenarios by tuning the estimations achieved and computationally simulate the behaviour of the queue under each one. The results indicate that the system could reach equilibrium at some point in the future and the model forecasts a slow decrease in the size of the waiting list in the short and mid…

Stochastic ordering of classical discrete distributions

2010

For several pairs $(P,Q)$ of classical distributions on $\N_0$, we show that their stochastic ordering $P\leq_{st} Q$ can be characterized by their extreme tail ordering equivalent to $ P(\{k_\ast \})/Q(\{k_\ast\}) \le 1 \le \lim_{k\to k^\ast} P(\{k\})/Q(\{k\})$, with $k_\ast$ and $k^\ast$ denoting the minimum and the supremum of the support of $P+Q$, and with the limit to be read as $P(\{k^\ast\})/Q(\{k^\ast\})$ for $k^\ast$ finite. This includes in particular all pairs where $P$ and $Q$ are both binomial ($b_{n_1,p_1} \leq_{st} b_{n_2,p_2}$ if and only if $n_1\le n_2$ and $(1-p_1)^{n_1}\ge(1-p_2)^{n_2}$, or $p_1=0$), both negative binomial ($b^-_{r_1,p_1}\leq_{st} b^-_{r_2,p_2}$ if and on…
