Low-dose Naltrexone for Post-COVID Fatigue Syndrome
Post-Viral Fatigue SyndromeThis study aims to determine if low-dose naltrexone (LDN) reduces fatigue, improves related symptoms, and reduces inflammatory markers in peripheral blood in cases with Post-COVID-19 Fatigue Syndrome (PCFS) from COVID-19 (i.e. confirmed SARS-CoV-2 case). LDN refers to naltrexone given in doses of 1-4.5 mg. Overall, studies have found that LDN is safe and well-tolerated. It may help to reduce pain and inflammation and improve well-being and immune function.The trial will be conducted by the Complex Chronic Diseases Program (CCDP) at BC Women's Hospital and will demonstrate whether LDN could benefit a large number of people with PCFS.

Effect of Gender on Distress and Fatigue in Cancer Patients
CancerDistress in cancer patients has been shown to be higher in females than males, but the behavior of distress during time in longitudinal prospective studies has not been studied, nor is it known if there are differences related to gender during time. These differences may have important therapeutic implications in terms of selective psychological support as cancer progresses during individual trajectories. The aim of the present study is to examine the effect of gender during time on psychological distress and fatigue in cancer patients across a broad range of cancer types. It is hypothesized that women will report higher psychological distress than men at initial visit but a reversed trend will be observed during follow-up as a result of different coping capabilities between men and women. We will also investigate if psychological factors (distress, anxiety and depression) affected antibody response and markers of COVID-19 vaccine activation (C-reactive protein, CRP and D-dimer) after 6 months from initial vaccination. Caregivers will also be interviewed to measure their burden with the Zarit Burden Interview. Patients attending a cancer outpatient clinic are invited to undergo a psychological session immediately before the medical visit. Distress is assessed by the Distress thermometer and fatigue by the ESAS-r scale at the end of the session. Patients will undergo follow-up visits to assess changes during time and possible time by gender interactions.

Amotivational Syndrome and Fatigue in Neurosurgery
Cerebral InjuryMotivation1 moreDepression is a major public concern associated with profound distress, intense suffering, and impairment in social, professional and familial functioning. Among the numerous symptoms defining depression, fatigue and motivation are not only frequent but also highly associated with poor quality of life and resistance to conventional antidepressant. Recent data, mainly obtained in animals, suggest that these symptoms may be linked to inflammatory processes within the central nervous system. Yet access to the brain is too invasive for exploring this link in patients with psychiatric conditions. However, certain conditions in neurosurgery, such as aneurysm rupture, require external evacuation, over several days or weeks, of the fluid bathing the brain through a catheter directly inserted into it. Critically, these patients also exhibit extreme exhaustion and fluctuating motivation, allowing to investigate the involvement of neuroinflammation in lack of motivation and fatigue by carrying out repeated motivation assessments with short behavioral tests (around ten minutes), while performing an analysis of inflammation markers in the fluid evacuated from the brain. The identification of inflammatory mechanisms underlying lack of motivation and fatigue could lead to the development of treatments for both resistant depression and motivation deficits that largely hamper rehabilitation in neurosurgery.

Cognitive Trance, Hypnosis and Meditation in Oncology
CancerDistress5 morePatients with cancer often suffer from a symptom cluster, including pain, fatigue, sleep difficulties, emotional distress and cognitive impairments. In oncology settings, there is a growing interest in "mind-body" intervention, to relieve them in a non-pharmacological way. Hypnosis and meditation are two modified state of consciousness shown to positively this symptom cluster. Cognitive trance is also a modified state of consciousness, but is induced by body movements and/or vocalizations. Subjective reports of experts in cognitive trance showed a modification of self, emotion regulation, pain perception, attention and concentration. However, we still need to develop studies to better characterise this particular state of consciousness and its clinical applications. Our randomized-controlled trial aims at comparing both interventions in terms of (1) benefits on cancer patients' quality of life (pain, fatigue, sleep, distress, cognitive impairments), (2) phenomenological/subjective experiences and neurophysiological correlates, and (3) mechanisms involved in patients' responsiveness, based on the biopsychosocial model of hypnosis.

Characterizing Fatigue Experienced by Cancer Patients Receiving Primary Treatment and Cancer Survivors...
CancerFatigue3 moreBackground: - Fatigue is a common side effect of cancer and its treatment. Up to 96% of patients with cancer have fatigue. The cause of fatigue in people with cancer or those receiving treatment is poorly understood, making fatigue hard to treat. More research is necessary to understand why cancer patients experience fatigue. Previous research has shown that fatigue may be caused by a number of factors, including problems with the immune system response of the body while undergoing cancer treatment. The researchers of this study are trying to understand how the immune system and other chemicals of the body change while a person receives cancer treatment and how these changes play a role in causing fatigue. The researchers are also interested in how a person s quality of life is affected by fatigue. Objectives: - To study fatigue in individuals who have cancer, are receiving cancer treatment, or have completed cancer treatment. Eligibility: Individuals at least 18 years of age. Receiving cancer treatment, OR completed primary treatment for cancer (e.g., cancer survivors), OR on active surveillance for localized cancer. Design: This study involves an initial screening visit and up to three outpatient visits. Participants will be screened with a medical history review (can be done virtually) and blood tests. A physical exam might also occur. Participants undergoing cancer treatment that has a clear completion date, will have the following visits: Before the start of treatment. At the end of treatment. At least 3 months after treatment ends. Participants not receiving treatment, are cancer survivors, or undergoing cancer treatment that does not have a clear completion date, will have up to 3 visits: Before the start of treatment or whenever you begin the study. At least 3 months after your first visit. At least 3 months after your second visit. At each study visit, participants will complete the following tasks (some of the tasks can be done from home or virtually): Questionnaires about physical activity, fatigue, depression, and quality of life (can be done at home or virtually). Have blood drawn. Physical activity device and journals to study how fatigue affects physical activity. Optional tests: Computer games testing your memory, attention, and ability to follow directions. Hand grip strength test to evaluate physical strength. Treatment will not be provided under this study.

Prevalidation of the First German Version of the Vocal Fatigue Index (VFI)
Vocal FatigueVocal fatigue has been described as a common complaint in patients with voice disorders, however to date there is no standardized questionnaire in german language to assess specific symptoms. Main aim of this study is to assess the validity of the first german version of the Vocal Fatigue Index (VFI), and english questionnaire developed for voice patients to assess vocal fatigue. In this study patients with voice disorders will receive the patient based questionnaires "Vocal Fatigue Index (VFI)", "Voice Handicap Index 9 international (VHI 9i)" and "Vocal Tract Discomfort Scale (VTD)", the study information and consent letter together with the standard invitation letter to a voice assessment at the Department for Phoniatrics and Speech Pathology University Hospital Zurich. Data of 93 consecutive volunteering patients will be collected. Furthermore a retest using the VFI will be conducted after 1 week with 10 volunteers. Thereafter construct validity of the VFI as compared to the established voice symptom questionnaires VHI 9i and VTD will be investigated. Further test-retest reliability will be determined.
