The aim of this study is to map the early development of children with DCD and the diagnostic trajectory in Flanders.
Obstructive lung disease is defined by limitations in expiratory airflow, caused by excess mucus, loss of muscle tone, and structural changes. Over time airflow reduction can lead to gas trapping in the lungs (hyperinflation). Hyperinflation is linked to diminished exercise tolerance, shortness of breath, and a poor quality of life. Early treatment options include inhalers and pulmonary rehabilitation; however, surgical intervention and oxygen therapy may be required in the later stages. More prompt, accurate diagnosis will help to improve patient outcomes and optimise their treatment pathways. Two methodologies used to determine lung volumes and hyperinflation, are nitrogen washout and body plethysmography. The accuracy of each in defining lung volumes in patients with obstructive lung disease is debated in literature. Plethysmography requires the patient to sit in an enclosed box and perform a panting manoeuvre and uses measured changes in volume and pressure to derive lung volumes. Plethysmography has been suggested to overestimate lung volumes in patients with obstructive lung disease. On the other hand, nitrogen washout relies on 'washing out' all the nitrogen from the lungs to calculate lung volumes. Gas trapping and poor airflow circulation that occurs in patients with airflow obstruction may lead to underestimated lung volumes. This study will aim to investigate if there is a significant difference between lung volumes obtained by both nitrogen washout and body plethysmography in patients with obstructive lung disease. Subjects with mild, moderate, severe, and very severe obstruction, including those with no obstruction for comparison will be included, with approximately 10 from each group. They will be asked if they consent to undergo an extra test during their routine hospital appointment, which will add ~15 minutes to their visit.
Frontline healthcare staff are frequently exposed to traumatic events at work (e.g., witnessing patients die), amplified by the COVID-19 pandemic. A significant proportion experience intrusive memories of these events that pop suddenly into mind: they can disrupt functioning and can contribute to post-traumatic stress disorder. Previous research has shown that a brief behavioural intervention can reduce the number of intrusive memories after a traumatic event. In this study we will test the effect of a digital imagery-competing task, a digital music-listening task and treatment as usual (TAU) for National Health Service (NHS) staff with intrusive memories of work-related traumatic events from the pandemic. We test the effect on the number of intrusive memories (primary outcome), and other clinical symptoms (PTSD, anxiety, depression, and insomnia), in addition to work functioning, general functioning and quality of life (secondary outcomes). Intervention feasibility, acceptability and implementation will also be explored (additional outcomes). We will recruit approximately 150 NHS staff (via the Intensive Care Society, social media and direct advertising by NHS Trusts) with intrusive memories of traumatic events experienced during the COVID-19 pandemic. The study is funded by the Wellcome Trust (223016/Z/21/Z).
Asthma is severe when it cannot be controlled with maximum-dose inhaled therapies while management of comorbidities and other precipitating or aggravating factors has been optimized. Allergic bronchopulmonary aspergillosis (ABPA) is a complex bronchopulmonary disease resulting from immunological reactions against Aspergillus Fumigatus. The development of a model of bronchial epithelium generated from patients with chronic lung disease will allow the modeling of bronchial tissue to understand the formation of these mucus plugs. This study aims to validate this model The investigators propose to verify the feasibility of obtaining and comparing two epithelia in two populations based on the following experiments: Differentiation of an Induced Pluripotent Stem cell (iPSC) clone derived from blood sample (Peripheral Blood Mononuclear Cells) of Type 2 inflammation (T2) severe asthma and Allergic Bronchopulmonary Aspergillosis (ABPA) in order to obtain differentiated bronchial epithelia in vitro.
Pain is a highly subjective and variable phenomenon. Different persons perceive objectively identical nociceptive stimuli differently. Moreover, the same person may perceive objectively identical stimuli differently in different situations, or even from one moment to another. In the brain, the processing of pain is associated with different neuronal responses originating from an extended network of brain areas. These responses include evoked activity as well as neuronal oscillations at alpha (8-13 Hz), beta (14-30 Hz) and gamma (30-100 Hz) frequencies. All these responses covary with moment-to-moment variations of pain within subjects (intra-subject variability). However, only the gamma response correlates with variations of pain between subjects (inter-subject variability). To date, it has remained unknown whether these relationships remain stable and reproducible across longer periods of time (inter-session-variability). Thus, the current project aims to systematically characterize how different pain-associated brain responses encode intra-individual, inter-individual, and inter-session variations of pain perception. To this end, the investigators will record pain-associated brain responses of 155 healthy participants at two different points in time. Each time, short painful stimuli will be applied to the participants' hand and they will be asked to verbally rate the perceived pain intensity, while pain-associated brain responses will be recorded using electroencephalography (EEG). This will allow to investigate the relationships between pain-associated brain responses and intra-individual and inter-individual variations of pain and to compare these measures and their relationships between sessions. In order to quantify the influence of demographic and psychological factors, i.e. age, mood and sleep quality / quantity on pain variability, established questionnaires will be used. In order to compare the functional significance of brain responses to other pain-associated neuronal responses, pain-associated responses of the autonomic system will be recorded and related to pain variability. Results of the project promise to elucidate the neuronal mechanisms underlying intra-individual, inter-individual and inter-session variability of pain. Such knowledge provides the basis for the development of a biomarker for pain, which might reasonably complement the self-assessment of pain. Moreover, as pain perception and objective stimulation tend to dissociate in pathological pain, the current project promises insights into the neuronal mechanisms of chronic pain.
The purpose of this study is to assess the effects of simultaneous administration of oral aspirin and oral ketamine as a therapeutic for those with Treatment Resistant Depression.
Neurodegeneration with brain iron accumulation (NBIA) represent a group of rare neurodevelopmental diseases, genetically as well as phenotypically heterogeneous. The diagnosis is based on brain MRI. It is also based on genetic testing. However overlaps exist between the different clinical presentations and the molecular diagnosis may be misinterpreted. Two main purposes must be addressed to get a better molecular diagnosis: on one hand reaching enough exhaustivity which may be performed with a larger gene panel and next generation sequencing; on the other hand, it is now necessary to validate or infirm the deleterious consequences of variants with the help of functional studies.
In our study, to show the effect of pneumoperitoneum on acute kidney injury in patients scheduled for laparoscopic surgery, NGAL and IGF-1 values will be measured before, after and 24 hours after pneumoperitoneum, and these values will be compared. In our study, we aimed to investigate the effect of pneumoperitoneum applied on acute kidney injury in patients who underwent laparoscopic surgery. Creatinine and NGAL have been used successfully in the follow-up of acute kidney injury. Our study investigates whether IGF-1 will be an effective indicator in acute kidney injury by comparing IGF-1 and NGAL values before pneumoperitoneum, after pneumoperitoneum and at the postoperative 24th hour.
Primary Obesity Surgery Endoluminal 2.0, or POSE 2.0, (USGI Medical, San Clemente, CA) creates full-thickness plications of gastric tissue endoscopically to shorten the stomach and narrow its aperture for weight loss in patients with obesity. Adults with obesity and non-alcoholic NAFLD were allocated based on preference and motivation to undergo the POSE 2.0 procedure with lifestyle modification or lifestyle modification alone to study the impact of the POSE2.0 procedures on NAFLD parameters and metabolic profile. Co-primary endpoints included improvement in controlled attenuation parameter (CAP) and resolution of hepatic steatosis at 12 months. Secondary endpoints included total body weight loss (TBWL), change in serum measures of hepatic steatosis and insulin resistance, and device safety.
