Filter by:esketamine is an optical isomer of ketamine. Compared with ketamine, esketamine has the characteristics of higher effective value, stronger receptor affinity, less adverse reactions of nervous system, and pharmacokinetics is controllable. Domestic and foreign studies have focused on the therapeutic effect of esketamine on major depression, but less attention has been paid to perioperative depression.This study intends to explore the effect of small doses of esketamine on patients with breast cancer.Postoperative depression and pain are observed.
Ketamine's efficacy as an antidepressant is now well established yet the mechanisms underlying its antidepressant effect are yet to be fully described. Work in the animal literature and research in humans is suggestive of specific effects on anhedonia and memory reconsolidation. In this study the investigators will further explore the effects of ketamine on learning and memory as well as measuring the associated changes at neural level in a sample of healthy volunteers. Participants will be assigned to receive ketamine or placebo and complete a set of tasks which will allow the investigators to quantify the effect of ketamine on learning about reward and punishment and memory for learned reward associations 24 hours after ketamine infusion. This study will help the investigators to understand the basis of ketamine's antidepressant effects and aid the development of new treatments for depression.
In the planned study, it was aimed to examine the effect of tele-education offered in the postpartum period in the covid 19 pandemic on the levels of depression, attachment and anxiety of women.
Ketamine is a dissociative anesthetic and powerful analgesic. At low doses, ketamine can desensitize the central pain pathway and modulate opioid receptors. Studies have generally found that preoperative use of ketamine can reduce opioid consumption by approximately 50% and sub-anaesthetic doses of it have a rapid antidepressant effect, especially refractory depression. Studies have confirmed that esketamine, the S(+) enantiomer of ketamine, has a stronger affinity for NMDA receptors, which can achieve the same effect at smaller doses. While the incidence of neuropsychiatric side effects is significantly lower. On March 4, 2019, the U.S. Food and Drug Administration (FDA) first approved esketamine nasal spray with a new mechanism of action for the treatment of adult patients with refractory depression. Based on the analgesic and antidepressant effects of ketamine, the investigators speculate that esketamine may be effective for patients with chronic visceral pain comorbid depression. At present, the research evidence in this area is relatively lacking. Therefore, this study aims to explore the difference in the efficacy and safety of esketamine as an adjuvant therapy and positive control drug-pregabalin in patients with chronic visceral pain comorbid depression. Detailed Description: According to the inclusion criteria and exclusion criteria, select patients with chronic visceral pain comorbid depression. Filtering and grouping period: During this phase, the patient will sign an informed consent form, and then conduct a structured clinical evaluation to determine whether it meets the "depressive disorder" in the DSM-IV-TR diagnostic criteria. According to the ICD-11, determine whether the patients have chronic visceral pain. Acute treatment period: Randomize patients into the following treatment groups: intravenous administration of esketamine (3 groups, 0.125, 0.25, 0.50 mg/kg), and duloxetine is co- administered orally. Pregabalin capsules were administered combined with duloxetine orally. observation period: After 2 weeks, esketamine treatment was discontinued, and observation was continued for 2 weeks. Maintain duloxetine and pregabalin treatment.
This study will recruit 30 subjects diagnosed with Major Depressive Disorder (MDD). Subjects will be recieve one infusion treatment of citalopram or placebo and 10 treatments of a form of transcranial magnetic stimulation, theta burst stimulation (TBS). Subjects will also undergo brain scans, quantitative electroencephalography (qEEG) brain activity recordings, and mood surveys. Study activities will be performed over the course of 4 weeks.
Post-acute sequelae of SARS-CoV-2 infection can cause multiple system function disorders, and complicated symptoms last for an extended period. The virus can cause this continued infection, or the virus causes immune system function disorder and post-infectious autoimmune disease. The clinical symptoms can be smell loss, taste loss to liver function disorder, kidney function failure, different. No matter how complicated the systems showed in the clinic, all of the symptoms are due to the specific cells being damaged. Our clinical study is focused on recovering the damaged structure and function of the cells that could restore the organ function back to normal or close to normal
This study will test a consumer health light therapy device (Re-Timer) for women with postpartum depression to better understand how it affects mood and the body clock (also called the circadian clock). Eligible participants will be enrolled and randomized after baseline assessments. In addition to using the Re-Timer light for 5 weeks participants will complete questionnaires at various timepoints, record sleep information, wear an actigraph watch, and provide saliva samples. Additionally, the sleep of the participants' infants will also be monitored using an ankle-worn device (actigraph) and sleep diary at certain time-points as this may influence the mother's mood/sleep, and in turn affect the results. The hypotheses regarding the bright light versus the placebo dim light of the study are: - morning bright light therapy will produce greater improvement from pre- to post-treatment on the Hamilton Rating Scale for Depression - morning bright light therapy will lengthen the Phase angle difference (PAD) and this will mediate change in depression symptoms. - morning bright light therapy will produce greater improvements on self-reported depression symptoms, excessive daytime sleepiness, maternal-infant bonding, social functioning, and sleep-related impairment from pre- to post-treatment.
This is a 12-week-long, randomised, double-blind, placebo-controlled trial exploring the efficacy of a high-EPA multinutrient supplement in the management of sub-clinical anxiety and depression. The investigators focus on young and healthy, adult university students, who may otherwise not be eligible for pharmacological or cognitive behavioural therapy interventions.
Pragmatic clinical trial of an add-on therapy regarding the use of edupression.com® - a licensed computer based self-help program - on patients with therapy-resistant depression receiving esketamine nasal spray
Major depressive disorder (MDD) is a common psychiatric condition, mostly treated with antidepressant drugs, which are limited for issues such as refractoriness, adverse effects and drug interactions, especially in the elderly population. In this context, the investigators investigate a non-pharmacological treatment known as recurrent transcranial magnetic stimulation (rTMS) with the theta-burst stimulation (TBS) method for the treatment of geriatric depression. This treatment modality has almost no adverse effects and avoids the risk associated with polypharmacy, providing an interesting alternative to antidepressant treatments. Our aim is to evaluate TBS efficacy in the treatment of geriatric depression in a randomized, double-blind, placebo-controlled clinical trial.
