Maternal Mental Health Access - MaMa
Postpartum DepressionPerinatal DepressionThis hybrid effectiveness-implementation project will allow the team to evaluate and refine implementation in preparation for future multisite trials to ultimately move the Evidence-Based Intervention (EBI) to scale among diverse populations. The plan is to enroll 120 at-risk pregnant and postpartum women from rural, urban, and Latino populations. Using a randomized preference design to also evaluate patient and sociocultural factors in participation and symptom trajectory. Using the Implementation Research Logic Model, the team will evaluate the implementation feasibility and acceptability of a remote-access and on-demand MBCT PD prevention intervention that is integrated within maternal clinical care settings using an existing patient portal. Successful achievement of the study aims will result in a refined implementation protocol for future studies that are sufficiently powered to evaluate the effectiveness of an integrated Digital Mental Health Technology and to estimate the cost/benefit ratio
Anesthesia Induction Schemes of Electroconvulsive Convulsions in Patients With Depression Based...
DepressionElectroconvulsive Therapy1 moreDepression is a common clinical mental disease with high incidence rate, high recurrence rate, high suicide rate and high disability rate. As a first-line treatment for depression with refractory, high suicide risk and obvious psychotic symptoms, electric shock has a definite effect on depression, but may lead to cognitive impairment. The induction of extensive epileptiform discharges in the cerebral cortex by electric shock therapy is the key to ensure the treatment effect. The level of epileptiform discharges in the brain is mainly reflected in the quality of convulsions. The quality of electroconvulsive convulsions is affected by factors such as age, stimulation power, anesthetic drugs and depth of anesthesia. Most anesthetics have anticonvulsive properties, such as barbiturate or propofol, which may have a negative impact on the quality of convulsions, thus affecting the therapeutic effect. If the parameters of electric shock, such as stimulation dose, are modified, although the quality and treatment effect of convulsions can be improved, it may also lead to higher cognitive side effects. The depth of anesthesia also affects the quality and efficacy of electric shock convulsions, and the quality of convulsions is higher when stimulated at a shallow level of anesthesia. However, if the use of narcotic drugs is reduced to improve the quality of convulsions, the risk of restlessness and delirium after electric shock may be higher and the comfort of patients may be lower. Therefore, this study compared the effects of different anesthesia induction schemes on the quality and clinical efficacy of electroconvulsive seizures in patients with depression based on EEG monitoring, and explored the optimal depth of anesthesia.
A Tailored and Digital Approach to Address Equity and Support Well-being for Healthcare Workers...
DepressionAnxiety2 moreFor this project the broad research objective is to evaluate the effectiveness of an enhanced digital wellbeing program in improving well-being, depression, anxiety, stress, resilience, and job satisfaction of physicians. The intent of the investigators is that this will enable a proactive culture of well-being and mental health support for the broader healthcare workforce during the multiple phases of the pandemic. The investigator's approach evaluates existing digital models which can be executed in a timely fashion and rapidly scaled for use across other health systems. Aim 1: Conduct interviews of URM and women physicians to identify barriers and facilitators to accessing and receiving digital well-being, mental health, and culturally sensitive support resources. Aim 2: Through a randomized controlled trial (RCT) investigate the immediate and long-term effect of a comprehensive well-being focused intervention (push text messaging, resource support, semi-facilitated peer groups hosted by Cobalt) vs. usual care on well-being, depression, anxiety, stress, resilience, and job satisfaction of physicians practicing in the era of COVID.
Ketamine Tolerated Dose for Postpartum Depression and Pain After Cesarean Delivery
PainPostoperative2 moreThe purpose of this study is to identify a tolerable dose for postpartum ketamine infusion using a maximum tolerated dose (MTD) 3+3 design. A loading dose over 1 hour will be the MTD variable to be tested, as our data suggest that ketamine side effects occur with the loading dose. The investigators hypothesize that subanesthetic ketamine dose will be well tolerated and any noted side effects will be rated acceptable by postpartum women following cesarean delivery.
The Mental Health Effects of a Mindfulness App in Parents of a Child With Medical Complexity
DepressionFamily Dynamics4 moreThe number of children with special health care needs (CSHCN) in the US is nearly 20% of children representing approximately 14.6 million children nationally. A subgroup of CSHCN are children who have the most intensive healthcare needs known as children with a medical complexity (CMC). Parents of CMC experience many challenges. In addition to typical caregiver tasks, parents of a CMC may experience added stress and are more likely to experience higher rates of anxiety, depression, and post-traumatic stress disorder than parents of healthy children. This project aims to explore the acceptability and feasibility of a mindfulness mobile application for parents of a CMC as well as determine the effectiveness of mindfulness application use on stress, depression, and family management in parents of a CMC. Forty-five participants will be recruited and given access to a mindfulness application and instructed to use it at least 4 days a week for at least 10 minutes. Parents will fill out questionnaires on app usage, as well as stress, depression, and family management. This work will be accomplished through a pilot single arm approach.
The Impact of AMPA Receptor Blockade on Ketamine's Anti-Suicidal Effects
Depressive DisorderMajor Depressive Disorder3 moreThe purpose of this study is to test the hypothesis that the anti-depressant and anti-suicidal effects of the N-methyl-D-aspartate receptor (NMDAR) antagonist Ketamine is critically dependent on stimulation of Alpha-Amino-3-Hydroxy-5-Methyl-4-Isoxazole Propionic Acid receptors (AMPAR).
Glutamate Emotion Memory Study
Treatment Resistant DepressionDepression1 moreClinical depression often includes a pessimistic view of things which have happened in the past and an impairment in the ability to experience pleasure or looking forward to things. A licensed drug called ketamine affects the levels of glutamate, a chemical messenger in the brain, and has been used as a treatment particularly for depression which hasn't got better with other types of medication. Glutamate plays a role in learning and memory so the investigators are interested in understanding how ketamine can affect how people with depression remember past negative and positive memories and how they experience reward. The investigators are conducting a study in depressed participants who did not improve with the standard antidepressant treatment to expand our understanding on how ketamine can influence memory, the way people understand emotions and learn from rewards and punishments. Study participants will undergo medical and psychiatric health screening, drug administration (ketamine or saline), questionnaires and computer tasks before and after the administration of the study drug, and an MRI scan after administration of the drug. MRI is a type of brain scan that allows us to see how the brain responds during for example memories of things which have happened in the past. This project will help us understand how NMDA antagonists may work in depression.
DBS for TRD With the Medtronic Percept PC
Major Depressive DisorderTreatment Resistant DepressionOf the estimated 30 million Americans who suffer from Major Depressive Disorder, approximately 10% are considered treatment resistant. Deep brain stimulation (DBS) to a region of the brain called the subcallosal cingulate (SCC) is an emerging strategy for treatment resistant depression (TRD), which involves placement of electrodes in a specific region of the brain and stimulating that area with electricity. This is believed to reset the brain network responsible for symptoms and results in a significant antidepressant response. A series of open-label studies have demonstrated sustained, long-term antidepressant effects in 40-60% of patients who received this treatment. A challenge to the effective dissemination of this fledgling treatment is the absence of biomarkers (objective, measureable indications of the state of the body and brain) to guide device placement and select stimulation parameters during follow-up care. By using a DBS device called the Percept PC (Medtronic, Inc) which has the ability to both deliver stimulation to and record electrical signals directly from the brain, this study aims to identify changes in local field potentials (LFPs), specific electrical signals that are thought to represent how the brain communicates information from one region to another, to see how this relates to DBS parameter settings and patient depressive symptomatology. The goal of this study is to study LFPs before and during active DBS stimulation to identify changes that correlate with the antidepressant effects of SCC DBS. The study team will recruit 10 patients with TRD and implant them with the Percept PC system. Participants will be asked to complete short questionnaires and collect LFP data twice daily for the first year of the study, as well as have weekly in person research procedures and assessments with the study team for up to one year. These include meetings with the study psychiatrist, psychologist, symptom ratings, and movement, voice, and video recordings. A brief discontinuation experiment will be conducted after 6 months of stimulation, in which the stimulation will be turned off and patterns of LFP changes will be recorded. The entire study is expected to last about 5 years, parcellated into several study phases. All participants are required to live in the New York metropolitan area for the first several months of the study.
