The goal of this observational study is to evaluate the safety and efficacy of various therapies used to treat ejaculatory and/or orgasmic dysfunctions in men. The objective is to create a large, national registry designed to capture key outcomes for men being treated for ejaculatory and/or orgasmic dysfunction. Participants will submit questionnaires about their diagnosis and treatment efficacy and multiple time intervals. Read Less

This study is looking at cells collected from the esophagus using a diagnostic device called the EndoSign® Cell Collection Device (a sponge on a thread). Subjects swallow a capsule, which dissolves in the stomach and releases a sponge that collects cells from the esophagus as the sponge is withdrawn using the thread. These cells will be tested to check for a condition called "Barrett's Esophagus." The cells from the sponge will be tested using Cyted Health biomarkers and compared to the results from a regular endoscopy and any biopsies that are taken. To do this, we need sponge samples from people who might have Barrett's Esophagus based on their risk factors, and from people with Barrett's Esophagus. Subjects will have one visit to have the Endosign Cell Collection Device administered prior to having a standard of care endoscopy. They will answer some questions about their medical history and experience with the cell collection procedure as part of the study. Data will be collected from medical records including post-endoscopy. Read Less

Oxycodone is an oral opioid analgesic that is most commonly prescribed for the management of pain in post-operative patients at Boston Children's Hospital. Oxycodone has been widely used in adults and children to relieve post-operative pain. However, its pharmacokinetics (what it does in the body) and pharmacodynamics (how it works) have not been well established in children. Some children, because of their specific genetic make-up, may metabolize the drug more quickly and therefore may be at risk for more side effects in the commonly prescribed dose. The investigators would like to find out more about how general anesthesia (GA) effects how this drug is absorbed, metabolized and excreted in children. In order to study these aspects, the investigators would like to give oxycodone to surgical patients (group one will receive oxycodone at the beginning of GA and group two will receive oxycodone at the end of GA) at Boston Children's Hospital then measure its metabolic activity and also perform a specific genetic analysis.

Compared to the knee and shoulder, the hip joint leaves relatively little space to maneuver arthroscopic instruments and camera. To expand the potential space in the hip joint, traction is commonly applied to the operative leg through a perineal post. This is an effective technique to improve the working space for arthroscopy, however it has been associated with complications, including perineal numbness. Traction pads, used alone or with a perineal post, can reduce pressure on the perineal area, thus reducing numbness. The investigators hypothesize that positioning hip arthroscopy patients using a traction pad on a standard traction table with a perineal post will reduce the incidence and duration of postoperative perineal numbness.

The objective of this study is to evaluate the efficacy of the COOLSTAT® Transnasal Thermal Regulating Device in reducing temperature in a population of febrile subjects who meet the inclusion/exclusion criteria. Read Less

The clinical trial aims to conduct a feasibility, acceptability, and usability clinical trial of a modular CBT-based and technologically enhanced intervention for people with an SUD and recently enrolled in IOP, probe target engagement and change in clinical outcomes, and examine attrition rates in IOP. This study will enroll 40 adults who are currently enrolled in IOP, have a substance use disorder, and experience elevated anxiety. 20 individuals will be randomized to the experimental intervention, "Intervention for Managing Physical Reactions to Overwhelming Emotions" (IMPROVE), and 20 individuals will be randomized to the active control group, "Physical Health Education Treatment" (PHET). Participants will be asked to complete a baseline assessment of mood, substance use, and psychophysiology. Participants will then completed ecological momentary assessments (EMA) via smartphone technology 4 times a day for \~ 28 days (the day following the baseline assessment until the 3rd intervention session). Participants will complete one 45 minute - 1 hour intervention each week for 3 weeks (either the IMPROVE or PHET intervention, pending randomization). Following the last intervention session, participants will return to the lab to complete a post-intervention assessment that mirrors the baseline assessment and then complete follow-up surveys 1- and 3-months post intervention.

Determining the etiology of cardiomyopathy is of high clinical importance for optimal treatment strategy and prediction of prognosis. There is increased risk for cardiovascular disease and higher propensity for cardiovascular related mortality among Black and non-Hispanic White patients. Recently, advanced cardiac imaging has become a vital tool in diagnosis and risk stratification of cardiovascular disease. Very limited data is available on the prevalence and characteristics of different cardiovascular diseases in Hispanic and African American minority groups, therefore, studying different racial and ethnic minority groups in the Bronx population is an exceptionally valuable source to determine the prevalence of cardiomyopathies among minority groups along with study survival in this population. This study aims to determine the etiology of cardiovascular disease in a diverse patient population by utilizing various cardiovascular imaging modalities, with a focus on cardiac magnetic resonance (CMR) imaging and to develop risk stratification models by applying advanced cardiovascular imaging markers.

The goal of this research study is to determine if the investigators can predict which participants will respond to endocrine therapy and a cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitor for metastatic breast cancer and which participants will not. Investigators will use information from the tumor tissue and serial blood samples. Investigators hope that a deeper understanding of which participants will respond to this combination and how resistance emerges will allow the investigators to better tailor therapies for metastatic breast cancer. Subjects will have archived tissue or new biopsy collected at study enrollment. This tissue will undergo special molecular testing. Subjects will also have blood collected at study enrollment and periodically thereafter. This blood will also undergo special molecular testing. Information from this testing will not be available to subjects or their treating physicians as the investigators do not know how this information should impact treatment. The investigators will collect information about which treatment the subjects receive and how their cancer responds. Any man or woman being seen at Johns Hopkins for treatment of newly diagnosed estrogen receptor positive (ER+) and/or progesterone receptor positive (PR+) metastatic breast cancer may be eligible.

The researchers doing this study think that performing scans of the brain and testing cerebrospinal fluid (CSF) in people with HER2-positive breast cancer may be an effective way of identifying the early onset of CNS metastases (such as brain cancer). If the researchers can identify the early onset of CNS metastases, they can immediately treat that cancer and possibly prevent it from worsening. Currently, people with breast cancer don't usually have scans of the brain or CSF testing unless they are experiencing symptoms of CNS metastases. Read Less

The key hypothesis for this study is that collection of the PRO surveys via the Outcomes4Me app is feasible, as measured by survey completion rates. In addition to informing feasibility, this study will provide information about symptom trajectories, symptom management interventions, and early endocrine therapy adherence and persistence. Patients with risk factors for adjuvant endocrine therapy non-adherence or early discontinuation will complete patient-reported outcome (PRO) surveys via smart phone app at baseline and 2, 4, 8 and 12 weeks after adjuvant endocrine therapy initiation. Since symptoms and side effects are a key driver of adjuvant endocrine therapy non-adherence and non-persistence, the investigators anticipate that enhanced detection of symptoms via use of PRO surveys will result in improved symptom management and, could thereby support treatment adherence and persistence. This pilot study will assess the feasibility of the PRO survey intervention. In this pilot study, feedback about the intervention will be obtained from patients and from members of the study teams and clinical teams caring for the patients who participate. Read Less
