The subject of doctoral dissertation: Assessment of the effects of a meatless, ketogenic restrictive diet on body composition, strength capacity, oxidative stress and immune response During planning of research and topic of the doctoral dissertation, it was considered how to modify a standard ketogenic diet rich in saturated fatty acids so that the use of this model of nutrition has the most anti-inflammatory effect. Therefore, it was decided to conduct a research to check whether a diet rich in omega-3 polyunsaturated fatty acids will show such an effect when following a high-fat diet. Hypotheses: 1. The ketogenic diet reduces systemic inflammation. 2.The ketogenic diet reduces oxidative stress. 3. The ketogenic diet reduces body fat. 4. A ketogenic diet does not worsen strength performance.
This study aims to pilot a world-first intervention, a mental health intervention augmented for children indicated with developmental language disorder (DLD). It serves as a proof-of-concept of how existing observational studies on these topics at the Centre for Research in Child Development (c.f. Tran-Sen; Gibber) can be translated into interventions. Mental health problems here are defined as anxiety type problems of social anxiety, specific phobia, separation anxiety and generalised anxiety. DLD is defined as a marked difficulty in oral language in the absence of biomedical causes (Bishop et al., 2017). This randomised pilot answers three uncertainties in preparation for a future definitive randomised control trial (RCT).
The current study examines the effectiveness of the StayFine app for relapse prevention of anxiety or depressive disorders in youth using a randomized controlled trial. In addition, ecological momentary assessment (EMA) is used to explore fluctuations in emotions, psychological factors as predictor of the intervention effect and potential differential mechanisms of change. A total of 254 healthy youths remitted from an anxiety and/or depressive disorder, aged 13-21 years old, will be recruited for the study. Participants will be randomized to either 1) use the StayFine app exclusively for monitoring, or 2) use the StayFine app for monitoring and interventions supported by an expert patient. Stratification blocks are of random size and depend on previous episodes (1/2/3 or more) and previous treatment (yes/no). The intervention is based on the well-established Preventive Cognitive Therapy (PCT) for relapse prevention for adults and Cognitive Behavioral therapy adapted for the relapse prevention phase, both supplemented for anxiety and adolescents. In both conditions adolescents monitor their symptoms five times in three years and feedback and treatment advice is given in case of relapse. The primary outcome will be time to relapse. Secondary outcomes are (core) symptoms of depression and anxiety, number and duration of relapses, global functioning and quality of life. Mediators and moderators will be explored. Exploratory endpoints are monitoring and wearable outcomes.
This study will aim to test whether specific neural circuitry changes, proposed on the basis of a neurocognitive model of anxiety, are a mechanism of action for Cognitive Behavioural Therapy (CBT) interventions. This study aims to provide a theoretical model of the neurobiological mechanisms of CBT's therapeutic effect, where there currently is none, and potentially allow for more targeted/specific approaches to anxiety disorders following the identification of key CBT mechanisms. The ultimate aim is to improve the efficacy of CBT, and more generally, psychological interventions for anxiety disorders.
Our sense of touch is essential to explore our environment and experience life and is based on signals from receptors in the body that are sensitive to different types of stimulation. The TACTHUM projects aims to investigate the fundamental firing of mechanoreceptors in the body to various external stimuli, with an end-aim to better understand the human somatosensory system and to apply this knowledge to provide comprehensive sensory feedback in prosthetics. We have a vast system of peripheral receptors in the skin and muscles that provide us with exquisitely detailed information about our everyday interactions. When there is injury to a body part, such as in amputation, there is a significant loss of somatosensory input. Prosthetic devices have greatly developmed in the past few years, especially with the introduction of useful sensory feedback. However, there is a lot to discover both about the workings of the somatosensory system and how to recreate this to give feedback in a prosthetic device. The main objective of the TACTHUM project is to understand how to recover and apply useful somatosensory feedback in prostheses for amputees. There are a number of other sub-objectives, to: 1. Determine how tactile mechanoreceptors encode the texture of natural surfaces during passive and active exploration. 2. Investigate how our sense of touch varies with emotional state. 3. Explore what happens to our sense of touch when we explore surfaces at different temperatures. 4. Understand the origin of our perception of humidity. 5. Investigate differences in the encoding of tactile information with age. 6. Determine the perceptions generated by the stimulation of single tactile afferents. 7. Study changes in spontaneous activity and responses to tactile stimulation on the residual limb of amputees. To accomplish these objectives, we will primarily use the technique of microneurography, in vivo recordings from peripheral nerves, to gain direct information about the firing of peripheral neurons in humans. In conjunction with this, we will use a variety of mechanical and thermal stimuli to excite somatosensory fibers and register the activity of other physiological and perceptual measures. This will allow us to gain a fuller understanding of how the incoming somatosensory signals are interpreted and processed. Overall, we aim to explore how more naturalistic tactile interactions are encoded and how these can be translated to provide realistic prosthetic feedback.
The POKAL-PSY project is a study that monitors participants for five years. The goal of the study is to identify distinguishable subtypes of depression on the basis of biomarkers and to gain insight into their prognostic significance.
This study will examine the pain-relieving effects of a transcutaneous electrical nerve stimulator device called a Quell for persons with multiple chronic overlapping pain conditions.
Demonstrating that diagnostics of the state of consciousness and cognitive functions of patients with consciousness disorders performed using C-Eye X (based on eye-tracking technology) allows a more objective assessment of state of patients who were wrongly diagnosed based on popular methods using in a clinical practice (like behavioural scales on paper forms).
This registry has the following objectives. First, according to the guidance of 2021 WHO of CNS classification, we constructed and externally tested a multi-task DL model for simultaneous diagnosis of tumor segmentation, glioma classification and more extensive molecular subtype, including IDH mutation, ATRX deletion status, 1p19q co-deletion, TERT gene mutation status, etc. Second, based on the same ultimate purpose of liquid biopsy and radiomics, we innovatively put forward the concept and idea of combining radiomics and liquid biopsy technology to improve the diagnosis of glioma. And through our study, it will provide some clinical validation for this concept, hoping to supply some new ideas for subsequent research and supporting clinical decision-making.
