EEG Data Quality: Determinants and Impact in a Multicenter Study of Children, Adolescents, and Adults with Attention-Deficit/Hyperactivity Disorder (…

2021

Electroencephalography (EEG) represents a widely established method for assessing altered and typically developing brain function. However, systematic studies on EEG data quality, its correlates, and consequences are scarce. To address this research gap, the current study focused on the percentage of artifact-free segments after standard EEG pre-processing as a data quality index. We analyzed participant-related and methodological influences, and validity by replicating landmark EEG effects. Further, effects of data quality on spectral power analyses beyond participant-related characteristics were explored. EEG data from a multicenter ADHD-cohort (age range 6 to 45 years), and a non-ADHD sc…

Longterm quality of life after oncologic surgery and microvascular free flap reconstruction in patients with oral squamous cell carcinoma

2016

Background Quality of life (QoL) has become increasingly important in cancer treatment. It refers to the patient’s perception of the effects of the disease and therapy, and their impact on daily functioning and general feeling of well being. Material and Methods n this prospective study, a total of 100 patients treated at our institution, completed the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire and the specific EORTC QLQ-H&N35 module. The questionnaires were distributed to the patients between 12 and 60 months postoperatively. Results Global QoL score was 58.3 and mean score for functioning scale was 76.7. Fatigue (28.7 ± 26.1), followed by fina…

Prospective study of nocebo effects related to symptoms of idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF).

2020

The exact causes of Idiopathic Environmental Intolerance Attributed to Electromagnetic Fields (IEI-EMF, i.e., experience of somatic symptoms attributed to low-level electromagnetic fields) are still unknown. Psychological causation such as nocebo effects seem plausible. This study aimed to experimentally induce a nocebo effect for somatic symptom perception and examined whether it was reproducible after one week. We also examined whether these effects were associated with increased sympathetic activity and whether interoceptive accuracy (IAcc) moderated these relationships. Participants were recruited from the general population and instructed that electromagnetic exposure can enhance somat…

Factors associated with the subjective health complaints among adolescents: Results from the ASSO Project

2019

Objectives. Subjective health complaints (e.g. headache and feeling low) are common among adolescents. The objective of this study was to identify the factors associated with the subjective health of adolescents from a population-based point of view. Material and methods. A sample of 712 students was recruited within the web-based Project ASSO (Adolescents and Surveillance System for the Obesity prevention), funded by the Italian Ministry of Health and piloted in Palermo. A 0-100 quantitative score (arbitrarily named "psychosomatic malaise index") based on the frequency of occurrence of seven subjective health complaints was created and used as outcome; socio-demographic characteristics, me…

Laparoscopic adrenalectomy in urological centres - the experience of the German Laparoscopic Working Group

2011

Study Type – Practice patterns (retrospective cohort) Level of Evidence 2b OBJECTIVE • To evaluate the safety and feasibility of laparoscopic adrenalectomy (LA) performed in several German centres with different laparoscopic experience, as LA has become the gold-standard approach for benign surgical adrenal disorders; however, for solitary metastasis or primary adrenal cancer its precise role is uncertain. PATIENTS AND METHODS • The data of 363 patients who underwent a LA were prospectively collected in 23 centres. • All centres were stratified into three groups according to their experience: group A ( 20 LAs/year). • In all, 15 centres used a transperitoneal approach, four a retroperitonea…

Haematological deficiencies in patients with recurrent aphthosis

2009

Background  Recurrent aphthosis is a common oral ulcerative condition consisting also of a subset of similar ulcers, properly named ‘aphthous-like’ ulcers (ALU), linked to systemic diseases and among these, to iron, folic acid and vitamin B12 deficiencies. Objectives  The main objectives of this study were: (i) to evaluate the association between recurrent aphthosis and the most common predisposing factors; (ii) to assess the frequency of ALU in recurrent aphthosis; (iii) to verify the efficacy of a replacement therapy in all ALU patients. Methods  Thirty-two adults with recurrent aphthosis and 29 otherwise healthy controls were consecutively recruited, interviewed and subjected to haematol…

2014

Management of osteonecrosis of the jaw associated with antiresorptive agents is challenging, and outcomes are unpredictable. The severity of disease is the main guide to management, and can help to predict prognosis. Most available staging systems for osteonecrosis, including the widely-used American Association of Oral and Maxillofacial Surgeons (AAOMS) system, classify severity on the basis of clinical and radiographic findings. However, clinical inspection and radiography are limited in their ability to identify the extent of necrotic bone disease compared with computed tomography (CT). We have organised a large multicentre retrospective study (known as MISSION) to investigate the agreem…

PO-58 - Cardiovascular risk profile in survivors of adult cancer - results from the general population study.

2016

The advancements in cancer treatment and detection of early cancer have resulted in steady increase of adult cancer survivors over the years. However, due to the long term toxic effects of chemotherapy and radiotherapy, the incidence of cardiovascular diseases (CVD) is increasing in survivors. Identifying risk factors and interventions to reduce the excess burden of CVD in this vulnerable population is urgently needed.To investigate the cardiovascular risk factors (CVRFs), inflammation and coagulation profile in cancer survivors from a large population-based study.Presence of CVRFs and laboratory markers have been compared in individuals with (n=1,359) and without (n=13,626) history of canc…

Magnetresonanztomographie in der Diagnostik des Kollumkarzinoms. Computertomographische und histologische Korrelation

1988

The value of magnetic resonance tomography in the diagnosis of carcinoma of the cervix was studied in a prospective series of 20 patients. The results were compared with those of computed tomography and with the clinical findings. The diagnosis depended on the postoperative histology. Gynaecological examination proved superior to imaging methods in determining the extent of local tumour spread. Tumour involvement of the regional lymphatic system was better demonstrated by MRT than by CT. Exact staging proved inadequate with both these methods and the new imaging methods have not produced any changes in operative planning or technique.

Endoscopic Management for Patients with Serrated Polyposis Syndrome is Feasible and Effective:

2014

Background and Study Aims: Serrated polyposis syndrome is a rare condition in which multiple serrated lesions develop all over the colon, which is thought to be associated with an increased risk for the development of cancer. The aim of this study was to investigate the feasibility of endoscopic treatment and standardised surveillance in patients with this increasingly recognised syndrome. Methods: From September 2010 to November 2013, consecutive patients were included in a prospective study. All patients underwent chromoendoscopy at first presentation and during surveillance. Follow-up examinations were carried out at 3 month intervals until complete clearance was achieved. Afterwards, pa…
