The LIFT will be conducted at Brigham and Women's Hospital (BWH) of Harvard Medical School, focusing on the effect of Pyridostigmine (Mestinon) and Low-Dose Naltrexone (LDN) in subjects aged 18-70 meeting the Canadian consensus criteria (CCC) for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) as well as having specifically Orthostatic Intolerance (OI). Long COVID (LC) subjects will also be included if they meet CCC and have OI. This double-blind, placebo-controlled study will involve 160 participants randomized into one of four possible groups: Pyridostigmine/LDN (40), Pyridostigmine/Placebo (40), LDN/Placebo (40), Placebo/Placebo (40). The dose of Pyridostigmine will be carefully titrated from 30mg to 60mg three times a day, and the dose of LDN will be titrated from 1.5 mg to 4.5 mg once daily. The trial includes a scale-back plan, allowing participants to reduce their dosage if they experience intolerance symptoms, with adjustments made during weekly visits. This plan provides a personalized approach to medication tolerance, ensuring participant's safety and comfort throughout the trial. The time commitment for the participant is approximately three (3) months, and during this time, there will be three (3) in-person visits to BWH and four (4) virtual visits. Study procedures will include two (2) submaximum cardiopulmonary exercise tests, questionnaires (virtually completed), and blood and urine collection. We will be recruiting from the BWH Dyspnea Clinic as well as the Open Medicine Foundation (OMF) StudyME Registry and anticipate the entire trial will take two (2) years to complete. The LIFT represents a significant endeavor to improve treatment options for ME/CFS patients and contribute to the broader understanding of this debilitating condition.

Background: Vaccines help prevent disease by causing the body to have an immune response. Many parts of this response happen in the blood. This response happens over days and weeks after getting the vaccine. Researchers want to how the blood changes over time in response to vaccines. They want to find out why vaccines work better for some people than for others. This could help make more effective vaccines. Objective: To learn about how the body responds to vaccines. Eligibility: Healthy people ages 18 and older Design: Participants will be screened with a medical history, physical exam, and blood and urine tests. Participants will have 9 visits over 6 months. All visits will include blood tests and a physical exam. Participants will have the first visit 1 week before they get the vaccine. Participants will get the flu vaccine at the second visit. The vaccine will be injected into the muscle of the upper arm with a needle. They will be watched for side effects for 15 minutes. Participants will have the next 2 visits exactly 1 day and 1 week after they get the vaccine. They will have the other 5 visits about 14, 28, 70, and 100 days after they get the vaccine. Participants will take email questionnaires about whether they had any side effects. Participants may have optional extra study visits. These will be no more than once a month for up to 1 year after they get the vaccine. Optionally, they can also repeat the study each year through the 2023 - 2024 flu season

Olfactory dysfunction is a defining symptom of COVID-19 infection. As the number of total, confirmed COVID-19 cases approached 19 million in the United States, it is estimated that there will be 250,000 to 500,000 new cases of chronically diminished smell (hyposmia) and loss of smell (anosmia) this year. Olfactory dysfunction is proposed to worsen numerous common co-morbidities in patients and has been shown to lead to a decreased quality of life. There are very few effective treatments for hyposmia or anosmia, and there is no gold standard of treatment. One proposed treatment option is smell training, which has shown promising yet variable results in a multitude of studies. It garners its theoretical basis from the high degree of neuroplasticity within the olfactory system, both peripherally and centrally. However, due to a relative inadequacy of proper studies on olfactory training, it is unknown what the most efficacious method in which to undergo the training is. This study proposes two novel procedural modifications to smell training in an attempt to enhance its efficacy. The investigators propose using a bimodal visual-olfactory approach, rather than relying on olfaction alone, during smell training, as well as using patient-preferred scents in the training that are identified as important by the study participant, rather than pre-determined scents with inadequate scientific backing. The investigators hypothesize that by utilizing bimodal visual-olfactory training and patient-selected scents, the olfactory training will be more efficacious and more motivating for participants.

COVID-19 testing is essential to controlling the COVID-19 pandemic to break transmission chains and reduce community transmission. However, Black and Latino/Hispanic populations in lower status frontline essential occupations such as food preparation, retail, building maintenance, personal services, and in-home health care have serious barriers to COVID-19 testing and, therefore, insufficient testing rates. The proposed study will use the multiphase optimization strategy framework to address the problem of low COVID-19 testing rates for this population: We will test the effects of four distinct candidate intervention components and then create an efficient multicomponent made up of the most effective combination of the components that can be rapidly scaled up in community settings to boost COVID-19 testing rates.

This is a multicenter, US-only, phase 1, open-label, dose escalation, non-randomized study of the safety, tolerability, and immunogenicity of investigational ChAd and SAM SARS-CoV-2 vaccines in healthy adult subjects. Homologous and heterologous prime-boost vaccination schedules (Stage 1), as well as boost(s) after receipt of COVID-19 EUA/licensed vaccines (Stage 2) will be examined. Subjects' willingness to receive ChAd vaccines will be assessed and documented at the time of informed consent and considered to determine group assignments. This phase 1 study will enroll 17 Stage 1 and up to 118 Stage 2 subjects. Eligible subjects will be enrolled in different groups based on their age (18-60 years old and >60 years old) and their EUA/licensed COVID-19 vaccination status. A sentinel approach with 72-hour (Stage 1, and Stage 2, Groups 5, 6, 8-10, 12, 13-15) or 7-day observation times (Groups 7 and 11) will be used, before recruiting the remainder of each dose escalation group. Decisions about dose escalation will be determined by the SSC with consultation with the DSMB as needed after all subjects in each group have been observed through Day 8 post first study vaccination. All subjects will be followed through 12 months after their last study vaccination. Vaccinated subjects will be carefully monitored for exposure and infection to SARS-CoV-2 throughout the study. Escalation to the highest dose (10 µg) of SAM-S-TCE in younger subjects will proceed only following safety assessments of the 10 µg dose in older subjects for a period of 28 days post-vaccination. In addition, the dosage of SAM-S-TCE given as a double boost to subjects previously vaccinated with the Johnson & Johnson/Janssen Ad26 COVID-19 EUA/licensed vaccine in Groups 8A, 8B, and 12A, 12B will be determined based on the dose escalation reactogenicity and immunogenicity results in Groups 5-7 and 9-11, respectively. After protocol version 9.0 was implemented, it was decided not to enroll subjects into Groups 7 and 8 because of competing priorities and predicted difficulties enrolling into these two groups. The primary objectives of this study are 1) To assess the safety and tolerability of different doses of ChAd-S or ChAd-S-TCE, and SAM-S or SAM-S-TCE when administered as prime-boost in healthy naïve adult subjects, 2) To assess the safety and tolerability of different doses of ChAd-S or ChAd-S-TCE, and SAM-S or SAM-S-TCE when administered as first or second boost in healthy adult subjects previously vaccinated with an mRNA or adenoviral-vectored COVID-19 EUA/licensed vaccine.
