Dose escalation vs. continued doses of paroxetine and maprotiline: a prospective study in depressed out-patients with inadequate treatment response

1997

In view of the fact that controlled prospective studies on the benefits of dose escalation of the selective serotonin re-uptake inhibitor (SSRI) paroxetine are lacking, we conducted a double-blind, randomized, parallel-group multicentre study designed to compare the possible benefits of dose escalation of paroxetine and maprotiline in patients suffering from major or minor depression according to modified Research Diagnostic Criteria (RDC) with inadequate treatment response. The study sample consisted of 544 out-patients with different degrees of severity of depression. Patients received either 20 mg paroxetine (n = 271) or 100 mg maprotiline (n = 273) for the first 3 weeks in a double-blin…

Surgical complications after endoscopic transsphenoidal pituitary surgery.

2009

Between January 2004 and June 2007 we conducted a retrospective analysis to assess post-operative complications related to endoscopic pituitary surgery in a series of 150 patients. Patients were treated with an endoscopic endonasal transsphenoidal approach to the sellar region for removal of pathological sellar and suprasellar lesions. We analysed the complications in groups according to the anatomical structures of the approach and the functional systems of the pituitary gland (anterior and posterior endocrine systems), and compared them to a large historical series using the traditional microsurgical transsphenoidal approach. Overall, we observed a decreased incidence of complications wit…

Polysomnography and ApneaGraph in patients with sleep-related breathing disorders.

2007

<i>Purpose:</i> To evaluate whether ApneaGraph (AG) and polysomnography (PSG) deliver comparable results in patients with sleep-related breathing disorders. <i>Procedures:</i> A prospective study was performed, which included 14 patients with obstructive sleep apnea syndrome. Apnea-hypopnea index (AHI), hypopnea index (HI), apnea index (AI), obstructive, central and mixed apnea, oxygen saturation (SaO<sub>2</sub>), pulse and body position were simultaneously assessed by PSG and AG in each individual. <i>Results:</i> There was a good correlation between measurements of AG and PSG for AHI, pulse, SaO<sub>2</sub>, body position and ce…

Clinical and prognostic value of 18F-FDG-PET/CT in restaging of pancreatic cancer

2018

Aim The aim of this retrospective multicentre study was to evaluate the clinical and prognostic effect of fluorine-18-fluorodeoxyglucose (18F-FDG)-PET/computed tomography (CT) in the restaging process of pancreatic cancer (PC). Materials and methods Data from patients treated for primary PC, who underwent18F-FDG-PET/CT for suspicious of disease progression, were collected. Accuracy was assessed employing conventional diagnostic procedures, multidisciplinary team case notes, further18F-FDG-PET/CT scans and/or follow-up. Receiver operating characteristic curve and likelihood ratio (LR+/-) analyses were used for completion of accuracy definition. Progression-free survival (PFS) and overall sur…

Duration of active psychosis and functional outcomes in first-episode non-affective psychosis.

2018

AbstractBackground:The duration of untreated psychosis (DUP) has been associated with negative outcomes in psychosis; however, few studies have focused on the duration of active psychotic symptoms after commencing treatment (DAT). In this study, we aimed to evaluate the effect of DUP and DAT on functional long-term outcomes (3 years) in patients with early psychosis.Methods:We evaluated the Scale for the Assessment of Positive Symptoms (SAPS) at frequent intervals for 3 years after presentation to determine the DAT for 307 individuals with first-episode psychosis together with DUP and clinical variables. The functional outcomes were assessed using the Disability Assessment Scale (DAS) at th…

Trends in mortality related to pulmonary embolism in the European Region, 2000-15: analysis of vital registration data from the WHO Mortality Database

2020

Summary Background European estimates of the burden imposed by pulmonary embolism are not available to this date. We aimed to assess pulmonary embolism-related mortality and time trends in the WHO European Region. Methods We analysed vital registration data from the WHO Mortality Database (2000–15) covering subregions of the WHO European Region: Eastern Europe, Northern Europe, Southern Europe, Western Europe, and Central Asia. Deaths were considered pulmonary embolism-related if International Classification of Disease-10 code for acute pulmonary embolism (I26) or any code for deep or superficial vein thrombosis was listed as the primary cause of death. We used locally estimated scatterplot…

Treatment Monitoring Program for Implementation of Adherence to Second-Line Erlotinib for Advanced Non–Small-Cell Lung Cancer

2012

Abstract Background Adherence to erlotinib could be a determinant for clinical outcome and treatment toxicity in patients with advanced non–small-cell lung cancer (A-NSCLC). Patients and Methods In an observational study, the Basel Assessment of Adherence Scale (BAAS), a visual analogue scale (VAS), pill counting, and missed appointment rate were used to evaluate adherence in a first cohort of patients who was prescribed erlotinib without a specifically designed management strategy and in a second cohort of patients followed by an oral treatment monitoring program. Results Adherence > 95% by BAAS at 2 months of treatment in the first and second cohorts was 72% and 84%, respectively ( P = .0…

Monitoring changes in anti-tuberculosis treatment: associated factors determined at the time of diagnosis

2013

OBJECTIVES: To determine predictive factors for changes in standard anti-tuberculosis chemotherapy at the time of diagnosis. METHODS: A prospective study was performed among tuberculosis (TB) patients treated at specialised centres during 2008-2009. Treatment outcome was monitored per standard guidelines. Treatment was considered successful if the patient was cured or completed treatment. Factors associated with treatment modification were analysed at the bivariate and multivariate levels using logistic regression. RESULTS: A total of 427 patients were included in the study. The initial standard treatment regimen was retained for 249 patients (58.3%), extended to 9 months for 36 (8.4%) and …
