Is ‘anxiety sensitivity’ predictive of postoperative nausea and vomiting?
2019
BACKGROUND Postoperative nausea and vomiting (PONV) is an extremely distressing side effect for patients. Despite PONV prophylaxis guided by well established scoring systems, the incidence of PONV is still high. OBJECTIVE The aim of the current study was to investigate the predictive value of anxiety sensitivity as an additional independent risk factor for PONV in patients with an increased risk of PONV. DESIGN A noninterventional, observational study. SETTING A tertiary care university hospital. PATIENTS Patients with an increased risk of PONV (i.e. female, nonsmoking) undergoing elective surgery (general, gynaecological, urological, musculoskeletal or neurosurgical) under general anaesthe…
The relationship between age and production of tumour necrosis factor-α in healthy volunteers and patients with chronic heart failure
2003
Ageing is associated with an altered immune response. Elevated plasma levels of tumour necrosis factor-alpha (TNF-alpha) are present in patients with advanced chronic heart failure (CHF). However, the relationship between age and the immune response in CHF is unknown.We investigated the relationship between age and the TNF-alpha generating capacity of lipopolysaccharide (LPS) stimulated peripheral blood mononuclear cells (PBMC) in nine healthy control subjects (mean age 51.6+/-3.6 years, age range 39-75 years) and 22 stable patients with CHF (mean age 68.3+/-1.5 years, age range 52-78 years, NYHA class 3.0+/-0.2). We also tested the TNF-alpha generating capacity of all control subjects and …
Impact of comorbidities on the severity of chronic hepatitis B at presentation.
2011
AIM: To evaluate the clinical relevance of each cofactor on clinical presentation of chronic hepatitis B. METHODS: Out of 1366 hepatitis B surface antigen (HBsAg) positive subjects consecutively observed in 79 Italian hospitals, 53 (4.3%) showed as the only cofactor hepatitis D virus (HDV) infection [hepatitis B virus (HBV)/HDV group], 130 (9.5%) hepatitis C virus (HCV) (group HBV/HCV), 6 (0.4%) human immunodeficiency virus (HIV) (group HBV/HIV), 138 (10.2%) alcohol abuse (group HBV/alcohol); 109 (8.0%) subjects had at least two cofactors and 924 were in the cofactor-free (CF) group. RESULTS: Compared with patients in group CF those in group HBV/alcohol were older and more frequently had ci…
Hepatitis C virus genotypes: distribution and clinical significance in patients with cirrhosis type C seen at tertiary referral centres in Europe
2001
The aim of this study was to evaluate the distribution and clinical significance of hepatitis C virus (HCV) genotypes in European patients with compensated cirrhosis due to hepatitis C (Child class A) seen at tertiary referral centres. HCV genotypes were determined by genotype-specific primer PCR in 255 stored serum samples obtained from cirrhotics followed for a median period of 7 years. Inclusion criteria were biopsy-proven cirrhosis, absence of complications of cirrhosis and exclusion of all other potential causes of chronic liver disease. The proportion of patients with types 1b, 2, 3a, 1a, 4 and 5 were 69%, 19%, 6%, 5%, 0.5% and 0.5%, respectively. Kaplan-Meier 5-year risk of hepatocel…
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…
Determinants of Dyspnea in Patients with Different Grades of Stable Asthma
2003
Dyspnea is a main feature of symptomatology in asthma, and its perception does not necessarily correlates well with airway obstruction. The aim of this study was twofold: (1) to identify factors determining the subjective degree of dyspnea in patients with different grades of stable bronchial asthma and (2) to compare various clinical methods existing for grading dyspnea. The investigation comprised 153 outpatients with stable asthma. The parameters studied were the following: demographic characteristic of subjects, baseline dyspnea score by means of three clinical instruments (baseline dyspnea index [BDI], Medical Research Council [MRC] scale, and modified Borg scale), asthma severity, sta…
What proportion of chronic obstructive pulmonary disease outpatients is eligible for inclusion in randomized clinical trials?
2013
<b><i>Background and Objective:</i></b> We aimed to explore to what extent an unselected population of chronic obstructive pulmonary disease (COPD) outpatients would be eligible for inclusion in randomized clinical trials (RCTs). <b><i>Methods:</i></b> Retrospective analysis of the clinical records of outpatient subjects with an ascertained diagnosis of COPD. COPD outpatients were assessed against the following inclusion criteria: 40 < age < 80 years, current or former smokers, forced expiratory volume in the first second (FEV<sub>1</sub>) <70% predicted, no long-term oxygen therapy, no other concomitant lung diseases and …
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…
Erratum to: Donor age and long-term culture do not negatively influence the stem potential of limbal fibroblast-like stem cells
2016
In regenerative medicine the maintenance of stem cell properties is of crucial importance. Ageing is considered a cause of reduced stemness capability. The limbus is a stem niche of easy access and harbors two stem cell populations: epithelial stem cells and fibroblast-like stem cells. Our aim was to investigate whether donor age and/or long-term culture have any influence on stem cell marker expression and the profiles in the fibroblast-like stem cell population.Fibroblast-like stem cells were isolated and digested from 25 limbus samples of normal human corneo-scleral rings and long-term cultures were obtained. SSEA4 expression and sphere-forming capability were evaluated; cytofluorimetric…
Age-related variation in mobility independence among wheelchair users with spinal cord injury: A cross-sectional study
2016
To evaluate age-related variation in mobility independence among community-living wheelchair users with spinal cord injury (SCI).Community Survey (2011-2013) as part of the Swiss Spinal Cord Injury Cohort Study.Community.Individuals aged 16 years or older with traumatic or non-traumatic SCI permanently residing in Switzerland and using a wheelchair for moving around moderate distances (10-100 m).Not applicable.Mobility-related items of the Spinal Cord Independence Measure-Self Report were matched to the three principal domains "changing basic body position," "transferring oneself" and "moving around." Binary outcomes ("independence" vs. "no independence") were created for every domain and a…
