Filter by:Rumination syndrome is a condition in which people repeatedly and unintentionally regurgitate undigested or partially digested food from the stomach, rechew it, and then either re-swallow it or spit it out. The mechanism of the disease is not well understood. The investigators believe that discomfort in the stomach during and immediately after meals may be an important factor for this disease. The reason for such discomfort can be due to an alteration of nervous regulation of the stomach. The investigators can study the nervous regulation that affects the stomach and other parts of the body by analysing in detail an electrocardiogram that is performed continuously for several hours. From this analysis, The investigators can study a parameter called cardiac vagal tone (CVT). Diaphragmatic breathing (DiaB) is a respiratory exercise, in which people mainly move their abdomen to breath. DiaB is a common treatment for rumination syndrome. Patients doing DiaB can reduce the number of rumination episodes. The mechanism by which DiaB improves rumination is unknown. There is another type of breathing called slow deep breathing (SlowDB), in which people mainly breathe with their chest. SlowDB is used as a therapy for increased pain in the food pipe (oesophagus) and it might also be effective on rumination syndrome. The investigators believe that both DiaB and SlowDB can improve rumination, by modifying the nervous control of the stomach (that the investigators can monitor by measuring continuously cardiac vagal tone (CVT)). The aims of the study are to investigate the association between gastric discomfort during a meal, CVT variations (measured with the electrocardiogram during the meal) and the severity of rumination episodes. The investigators will also study how DiaB and SlowDB can modify this variable during the test. In a second step, The investigators will assess the clinical effect of respiratory exercises (DiaB and SlowDB) on the severity and frequency of regurgitations in patients diagnosed with rumination syndrome. Method This research consists of two separate studies. 1. Study1 (to investigate the mechanism of rumination syndrome) 10 healthy volunteers and 10 rumination patients will join Study1 on 3 separate days. On each visit, the investigators will place electrocardiogram sensors and a belt that can measure the thorax or abdominal movement. All subjects will get instructions to perform SlowDB or DiaB, answer some questionnaires, eat the test meal, perform normal breathing/DiaB/SlowDB for 15 minutes, and stay quietly on the chair for 3 hours. 2. Study 2 (to assess the effect of DiaB and SlowDB on rumination syndrome) 10 patients with rumination syndrome will join Study 2. On the first visit, subjects will have the test meal, answer the symptom questionnaire 1 hour after the meal, and learn how to perform either DiaB or SlowDB. After the first visit, subjects perform DiaB or SlowDB during 15 minutes after every meal for 4 weeks. On the second visit, subjects will have the test meal, answer the symptom questionnaire 1 hour after the meal, and learn how to perform the other respiratory exercise. After a 2-week break, subjects will perform the other respiratory exercise for the next 4 weeks. On the last visit, subjects will have the test meal and answer the symptom questionnaire 1 hour after the meal.
Rumination involves focusing on negative emotions repeatedly and is a risk factor for developing depression, anxiety, and self-injury. These negative outcomes increase in adolescence. The main goal of this study is to examine whether a mobile application designed to reduce rumination works with adolescents. The mobile application involves mindfulness exercises. Mindfulness means nonjudgmentally and deliberately paying attention. Adolescents will be randomly assigned to either the mindfulness group or a control group who uses a mobile application without mindfulness exercises. Both groups will use the app three times per day for three weeks and we will follow up with participants for six months. The investigators hypothesize that the mindfulness group will experience a reduction in rumination and symptoms of depression, anxiety and self-injury. They also expect that the mindfulness group will find the mobile app to be more engaging and will continue to use it beyond the 3 weeks.
The purpose of this research is to test whether Mindfulness-Based Therapy for Insomnia (MBTI) significantly reduces symptoms of insomnia and cognitive arousal in patients with treatment-resistant insomnia.
The purpose of this study is to investigate the basic psychological and neural mechanisms underlying the social regulation of emotion - that is, how one person's actions can impact, or regulate - the emotions of another person - and how this ability changes with practice. As such, this study is not designed to directly address clinical health outcomes and provide no treatment or intervention.
This project will assess the effectiveness of a stepped-care model (i.e. digital Cognitive Behavioral Therapy for Insomnia (dCBT-I) followed by face-to-face CBT-I) in improving severity of insomnia and sleep outcomes in an insomnia cohort. This project will also investigate the effectiveness of this stepped-care model in prevention of major depressive disorder, and will test rumination as a mediator of treatment response.
Patients with a clinical suspicion of rumination syndrome and/or supra-gastric belching are randomized into baclofen or placebo for 2 weeks (10mg, tid). thereafter, they undergo a high resolution impedance manometry measurement, were they receive a solid meal, and recordings continue for another hour. Thereafter, they will receive the alternative treatment, after which they will undergo a second high resolution impedance manometry measurement. Patients are asked to fill out questionnaires during the entire study period.
The purpose of this study is to examine if an internet-based exposure therapy is effective in reducing excessive worry amongst patients who suffer from this problem.
The investigators propose to examine both resting state activity and functional activity during rumination and during self-processing to study the relationship between neural correlates of rumination/self-focus and self-processing in major depression and bipolar disorder.
Repetitive negative thinking (RNT) plays an important role in different psychiatric disorders, such as depressive and anxiety disorders, complicated grief, posttraumatic stress disorders, anorexia nervosa. RNT is seen as a vulnerability factor in the onset, duration, severity and relapse of those disorders. Although there is a lot of theoretical research, it is unknown if a group training protocol addressing RNT has an additional effect on Treatment as Usual (TAU) of patients with GAD or Depressive disorder. Our hypothesis is that a training intervention will show a significant effect on declined RNT activity (measured by PSWQ and LARRS), reduced identification with worrying/rumination (measured by CFQ-13 and a Visual Analogue Scale), and reduced scores on metacognitions questionnaire (MCV Dutch version of the MCQ), when compared to TAU (medication, psychotherapy or a combination of both treatments). Further we expect that this effect on RNT will not be temporary and the beneficial effects will remain present over a longer time (9 months). Our third hypothesis claims that reduced RNT will have an effect on Quality of Life, self-esteem and depressive and anxiety scores (measured respectively by WHO-QoL, Rosenberg Self Esteem Questionnaire, BDI-II and STAI; all of them in Dutch version). Fourth hypothesis concerns the effect of the training in the functioning on a neurobiological level. Here we expect that the beneficial effects of training on RNT will increase top-down prefrontal (dorsolateral) cortical control over an overactive bottom-up limbic system. To examine these neurobiological effects, we apply a multimodal approach where we combine resting state fMRI, structural MRI such as diffuse tensor imaging (DTI), anterior spin labelling (ASL). Further, in our department we developed an audio critique task where participants hear different kinds of critique amongst some of negative valence which will be especially problematic for ruminative patients reflecting difficulties and differences these top-down/bottom-up processes when compared to a healthy control group at baseline. Further, we hypothesize that only when coping with RNT is successful these neuronal processes will normalize. We do not expect changes in the waiting list group. To examine these clinical and neuronal effects, people suffering from GAD and/or depression will be allocated by randomisation to an active treatment condition (ATC) and a waiting list control group (WLC). All the participants will be patients treated by general practitioner, psychologist or psychiatrist. Training exists of 8 sessions in group (max 12 participants) on a weekly basis, except for the last session, which takes place after one month). During the training people will get information on RNT, they will be trained in re-allocation of their attention, will receive some basic ideas about becoming aware of dysfunctional thinking and learn coping strategies such as stimulus control and engaging in positive activity. Assessments will take place before and after treatment for the ATC. The WLC will be measured at the start of the WLC and 12 weeks later. Measurement takes place by means of questionnaires and fMRI. During the fMRI, people will undergo a resting state paradigm and some tasks triggering RNT. 3 and 9 months after the group treatment, participants will be evaluated again on RNT by means of questionnaires. Participants in WLC will receive group treatment from the moment the parallel active treatment condition is ended (e.g. after 12 weeks). This group will be evaluated immediately after training and at 3 and 9 months follow-up. At the end of the training, after the 8th session, two participants per run will be asked to cooperate in a qualitative in-depth interview. We are interested in linking results with the group training with some factors such as quantity of sessions, degree of active participation in between sessions. We are also interested in defining which interventions are perceived as most useful and if there is a link between disorder and the usefulness of some interventions.
Rumination is an upper gastrointestinal (GI) disorder characterized by the frequent regurgitation of recently ingested food. Very little is understood about the nature and treatment of this disorder. The act of regurgitation in rumination involves the opening of the upper esophageal sphincter and the muscular contraction of the abdomins rectus. Behavioral treatment of these symptoms is the clinical intervention of choice; however, only uncontrolled case documentation exists to support its effectiveness. However, an effective behavioral mechanism may be relaxation of the muscles. From a behavioral standpoint, muscular relaxation is incompatible with the necessary muscular contraction for rumination. To date, single case documentation and few designed single case studies have examined the clinical effectiveness of behavioral interventions for GI rumination. In the current study, the investigators seek to examine the effectiveness of two behavioral relaxation interventions for GI rumination through a treatment as usual paradigm (proposed N = 20). Our primary goals are to examine the clinical effectiveness of these interventions in symptom reduction at 1- and 3-month follow-up.
