LATE-BREAKING ABSTRACT: Comparative studies on bronchuswall-thickness by histologic and computed tomographic measurements of porcine lungs
2015
Aims: Histologic slides are commonly used as template in the evaluation and development of medical imaging methods.Diseases like Asthma and COPD show characteristic changes in airway morphology and airway measurement by computed tomography is a promising diagnostic approach.However,shrinkage caused by fixation and histological processing is known in lung tissue.In this study,the thickness of bronchus walls in paraffin and frozen sections as well as in CT and MicroCT were compared. Methods: Airway measurements of swine lungs were performed after freezing in ventilated condition in liquid nitrogen by measuring the wall thickness of 7 bronchi via CT and MicroCT as well as in frozen and paraffi…
Intraoperative DNA methylation classification of brain tumors impacts neurosurgical strategy
2021
Abstract Background Brain tumor surgery must balance the benefit of maximal resection against the risk of inflicting severe damage. The impact of increased resection is diagnosis-specific. However, the precise diagnosis is typically uncertain at surgery due to limitations of imaging and intraoperative histomorphological methods. Novel and accurate strategies for brain tumor classification are necessary to support personalized intraoperative neurosurgical treatment decisions. Here, we describe a fast and cost-efficient workflow for intraoperative classification of brain tumors based on DNA methylation profiles generated by low coverage nanopore sequencing and machine learning algorithms. Met…
Small bowel angiodysplasia associated with von Willebrand's disease: report of a case.
2006
The association between angiodysplasia (AD) and von Willebrand's disease (vWD) was first described by Quick in 1967. The clinical course of patients with vWD and AD is characterized by multiple admissions to hospital for gastrointestinal bleeding, necessitating transfusions of packed red cells, factor VIII, and von Willebrand factor concentrates. The therapeutic management of these patients is difficult. Both medical and endoscopic techniques have been tried, but no treatment modality has been completely successful. We describe the clinical course of a patient affected by vWD, who suffered repeated massive gastrointestinal bleeding caused by small bowel AD. Intestinal resection was the only…
Endoscopic Resection of Early Esophageal and Gastric Neoplasias
2009
The advent of endoscopic resection (ER) techniques has enabled gastroenterologists to remove premalignant or neoplastic lesions throughout the gastrointestinal tract. This review discusses the indications and the several techniques of ER in early carcinomas of the esophagus and stomach. Before ER is performed an accurate evaluation of patients and careful staging of lesions is mandatory. After ER of the neoplasia histological assessment of the entire specimen with detailed histological analysis of layer infiltration is crucial. First long-term follow-up studies of large numbers of patients confirm the excellent effectiveness of ER for well-differentiated mucosal lesions without lymphangitic…
Predictors of nurses' attitudes and knowledge towards pain management in Italy. A cross-sectional study in the hospital settings.
2021
Abstract Introduction Pain is multidimensional, and as such it is the chief reason patients require urgent health care services. If inadequately assessed and untreated, pain may negatively impact on the quality of life of the patient. Pain management is an essential part of Nursing. The aim to this study is to examine the level of knowledge and attitudes with regard to pain among Italian nurses who work in clinical settings. Methods The Ferrell and McCaffery's Knowledge and Attitudes Survey Regarding Pain was distributed to 266 nurses employed in one specialized hospital in Rome, Italy. The staff in the survey work in three different settings: the intensive care unit, the sub-intensive care…
Depression, anxiety and health status across different BMI classes: A representative study in Germany
2020
Abstract Background Changes in body mass index (BMI) over the course of one's lifetime are related to the development of mental disorders. In the current study we compared symptoms of depression, generalized anxiety as well as general health status in the four BMI-classes: underweight, normal weight, overweight and obesity. Furthermore, mediator role of general health status on the relationship between BMI and depression and generalized anxiety was analyzed. Methods A representative sample (random-route sampling) of the German population (N = 2350) was investigated in a cross-sectional survey by measuring the three questionnaires PHQ-9, GAD-7 and EQ-5D-5L. Results The results showed signifi…
Particulate Matter Exposure and Attention-Deficit/Hyperactivity Disorder in Children: A Systematic Review of Epidemiological Studies
2019
Attention-deficit/hyperactivity disorder (ADHD) is the most common cognitive and behavioural disorder affecting children, with a worldwide-pooled prevalence of around 5%. Exposure to particulate matter (PM) air pollution is suspected to be associated with autism spectrum disorders and recent studies have investigated the relationship between PM exposure and ADHD. In the absence of any synthesis of the relevant literature on this topic, this systematic review of epidemiological studies aimed to investigate the relationship between the exposure of children to PM and ADHD and identify gaps in our current knowledge. In December 2018, we searched the PubMed and EMBASE databases. We only included…
Analysis of Caesarean Section Rates Using the Robson Classification System at a University Hospital in Spain
2020
Background: The WHO recommends the use of the Robson ten-group classification system (RTGCS) as an effective monitoring and analysis tool to assess the use of caesarean sections (CS). The present study aimed to conduct an analysis of births using the RTGCS in La Ribera University Hospital over nine years and to assess the levels and trends of CS births. Methods: Retrospective study between January 1, 2010, and December 31, 2018. All eligible women were allocated in RTGCS to determine the absolute and relative contribution made by each group to the overall CS rate
Physical Condition Factors that Predict a Better Quality of Life in Women with Fibromyalgia
2019
What physical qualities can predict the quality of life (QoL) in women with fibromyalgia (FM)? QoL is a very complex outcome affected by multiple comorbidities in people with fibromyalgia. This study aims to determine which physical qualities can predict the quality of life in women with FM. Also, a comparison between the physical qualities of women with FM and healthy counterparts was conducted. In total, 223 women participated in this cross-sectional study, 123 with FM, with ages ranging between 45 and 70 years. The study was conducted at several fibromyalgia associations and specialized medical units. QoL was measured as the main outcome. In addition, functional capacity, muscular streng…
