This is a single-arm, observational study of HIV-negative MSM with substance use disorder. Those who meet pre-screening criteria will attend a Screening Visit (Visit 1), where the informed consent process will be conducted and study eligibility will be confirmed. Eligible participants will attend three additional visits over the course of the study - the Enrollment Visit (Visit 2), Month 1 Visit (Visit 3), and Month 2 Visit (Visit 4). Participants will take one PrEP digital pill per day, for 60 days total, while using the digital pill system (DPS) and Beiwe, a digital phenotyping app. On nonadherent days, participants will receive brief surveys prompting them to report the reasons for their missed dose, as well as their engagement in substance use and sexual activity. Timeline followback will be conducted at the Month 1 and Month 2 Visits to understand the context of any nonadherence. Qualitative user experience exit interviews and dried blood spots (DBS) will be conducted at the Month 2 Visit.

Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. Some OSA patients with low arousal threshold wake up prematurely during an obstructive event and do not have time for spontaneous upper airway (UA) dilator muscle recruitment. As a consequence they are exposed to apnea and hypopnea cycling. In this protocol the investigators will test the effect of trazodone administered before sleep on OSA traits and OSA severity during sleep.

The goal of the Molecular Characterization Trial (MCT) is to obtain biological specimens and data resources from patients enrolled on prospective trials, to ensure that the Harvard/UCSF ROBIN Center accomplishes its key objective of advancing our understanding of the biological mechanisms that underlie how radiation treats tumors but also can cause unwanted side effects. The MCT focuses on collection of research biospecimens before, during, and after radiation. Also critical to the MCT is the deep annotation of these research biospecimens with elements that complement each other to provide a holistic, detailed view of each patient. Annotated elements include those used in the past such as clinical and biological features but extend to factors we have so far neglected but must incorporate in the future such as dosimetry (precise anatomical measurement of radiation dose), artificial intelligence, computational biology, and natural language processing.

Obstructive sleep apnea (OSA) is a highly prevalent disorder with adverse neurocognitive and cardio-metabolic outcomes. Continuous positive airway pressure (CPAP) is the gold standard therapeutic option to treat airway obstructions during sleep and thus, prevent its adverse cardiovascular and neurocognitive outcomes. Previous clinical trials, however, have largely failed to show a consistent impact of CPAP on these health outcomes. One of the main limitations of these trials may be the inadequate characterization of OSA and its acute physiological consequences. By characterizing OSA based on the "apnea-hypopnea index (AHI)", there is a potential risk of negative results. In this trial, the investigators intend to tackle this issue, by better characterization of OSA-related physiological consequences during sleep using physiologically driven metrics to capture the burden of OSA-related hypoxemia ("hypoxic burden"), autonomic response ("heart rate burden"), and sleep fragmentation ("arousal burden").

Hypothesis: The investigators hypothesize that genetic variants will alter gene expression in response to ischemia during cardiopulmonary bypass. To test this, the investigators will be taking small pieces of heart tissue from patients undergoing heart surgery before and after this period of ischemia. This will be compared to blood gene expression in blood cells and analyzed with the patients' genetic profile. This might allow us to assess the amount of inflammation that occurs when patients are on the heart-lung machine as well as examine the effects genes have on this critical time period.
