Diagnosis and treatment of sleep apnea with continuous positive airway pressure (CPAP) therapy has been shown to decrease arrhythmia recurrence in patients with AF following ablation. However, patients with AF undergoing ablation are not routinely screened for sleep apnea, despite an estimated sleep apnea prevalence of 25% in the general population, and perhaps higher among patients with AF. Home sleep testing is frequently used for evaluation of sleep apnea.

The etiology and pathogenesis of interstitial cystitis (IC) and its related condition in men, chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) has remained elusive. This has hampered development of mechanistic treatment strategies for these common, chronic and distressing medical conditions. We believe that IC and perhaps CP/CPPS are a spectrum of complex but inter-related genetic and acquired diseases resulting from the interaction of several genes regulating immune/inflammatory and neurogenic parameters and environmental factors/circumstances or exposure, culminating in the combination of pain, frequency, urgency and sexual specific symptoms. New research has delineated the dynamic and powerful association of the immune and neurogenic system in pain activation. An immune-modulated neurogenic model of IC illuminating the action of immune derived substances and pain related substances might be important in discovering the determinants of pain, voiding dysfunction and gender specific sexual problems. This inter-related dynamic model of IC disease pathogenesis could be explored for potential avenues leading to novel diagnostic and treatment strategies. We plan to identify and evaluate the sensitivity and specificity of several novel nerve and inflammation related markers in the diagnosis and follow up of IC (and CP/CPPS). By correlating the levels of urine immune and pain related substances to disease mechanisms, severity and progression, we may be able to create a human disease specific model for diagnosis and treatment.
The purpose of this study is to determine whether administration of a pecto-intercostal fascial plane block (PIFB) with bupivacaine is a more effective therapy for postoperative analgesia after cardiac surgery as compared to patients who receive a sham block of normal saline.
The main purpose of this research project is to study how seizure-like activity affects the blood flow in the brain of patients with Alzheimer's disease (AD). Changes in blood flow can change memory and thinking ability, as happens in Alzheimer's disease. The investigators are using a study drug called Levetiracetam, which helps control seizure-like activity to see if it can help change the abnormal blood flow in the brain that is seen in some people with Alzheimer's disease.
Swallowing difficulties are common after a stroke and can lead to serious complications like pneumonia and malnutrition. Unfortunately, there are no effective treatment for improving swallowing in stroke patients.
Previous investigations have shown that recovery of swallowing functions occurs from reorganization ("rewiring") of the non-involved cerebral hemisphere. In this study, the investigators propose to investigate a new intervention, which combines, swallowing exercises with brain stimulation targeted to the non-involved cerebral hemisphere, using low intensity current in acute stroke patients. The investigators plan to assess the safety of this technique in this patient population and also assess its effect on improving swallowing functions and swallowing physiology. During this time trial participants will undergo standardized swallowing and neurological assessments as well as brain MRI scans.
This is a single-arm open label trial for hospitalized patients with COVID-19 (Coronavirus). The primary endpoint of the study is to assess the requirement for mechanical ventilation in patients who are admitted to the hospital with COVID-19 infection and a Pulse Oxygen Level
The main purpose of this research program is to reduce the burden of end-stage organ disease on individuals, families, healthcare systems, and society by increasing the availability of donor organs for transplantation. Consistent with this aim, the project further examines strategies to increase access to and reduce disparities - racial, economic, gender - in live donor kidney transplantation (LDKT). Specifically, we expand the research and intensity of an innovative House Calls intervention developed by the principal investigator by including other minorities and socioeconomically disadvantaged patients and by adding a novel Patient-Centered Decision Support component. The main study hypothesis is that participants receiving the novel intervention (House Calls + Patient-Centered Decision Support) will have a higher proportion of LDKT's by the 2-year study endpoint.
The main purpose of this study is to learn which educational method is most helpful to patients and their family members when they consider whether to pursue live donor kidney transplantation.
Patients who are eligible for a kidney transplant usually get information in the transplant clinic about two types of kidney transplants - one where the kidney comes from a dead donor and one where the kidney comes from a healthy living donor. Patients are given this information by a transplant nurse or doctor and then encouraged to discuss it with family members and friends.
In this study, we are trying to see if changing how and where we give patients this information makes a difference in how patients and their family members think about live donor kidney transplantation. So, we are looking at whether getting the information in the transplant clinic - either alone or in a group - is the same or different than getting the same information in your home.
The study is only recruiting African American patients. This is being done because African Americans have a higher likelihood of developing chronic kidney disease and needing a kidney transplant than patients of other races. However, they wait longer for a kidney transplant and die at a higher rate on the waiting list because they are less likely than other patients to receive a live donor kidney transplant. We want to see which educational approach works best with African American patients and their families.
The purpose of this study is to assess magnetic resonance imaging (MRI) as a tool to track tumor growth for renal cell carcinoma while participants are on clinical treatment therapy of sunitinib and AMG386. An MRI is a type of scan that uses powerful magnets to make clearer images or to focus on detailed medical information in the abdomen and pelvis. The imaging done for this study will use the arterial spin labeling (ASL) MRI technique that allows us to see blood flow changes which possibly may indicate changes in tumor growth. Participants will be on a clinical trial for the treatment.
This randomized control trial will compare opioid use, pain, and functional outcomes following decompression surgery for single-level lumbar radiculopathy in patients who undergo placement of corticosteroid epidural injection within 2 weeks prior to surgery compared to those who do not. The hypothesis of this study is that patients who receive the preoperative corticosteroid injection will have less reduced postoperative opioid use, as well as earlier mobilization, reduced length of stay, and faster return to work compared to control patients who do not receive the injection.
The purpose of this trial is to determine whether using a brain training program in the time leading up to as well as after heart surgery will reduce confusion and cognitive loss that can occur after surgery.
The goal of the Novel Language Intervention for minimally verbal children with Autism Spectrum Disorder (ASD) is to test the efficacy of one experimental treatment (AMMT) compared to baseline assessments and compare the AMMT efficacy to a control intervention (SRT), both treatments were designed to facilitate speech output in minimally verbal 5.5 to 12.0 year olds. This study aims to compare the two interventions (one intonation-based; the other non-intonation-based) in a single-blind, randomized controlled trial (RCT) that includes a comprehensive baseline assessment battery, 25 intensive 1-on-1 treatment sessions conducted 5 days/week, and a series of probe assessments administered at multiple timepoints pre-, during, and post-therapy.
Despite the complex needs of minimally verbal children with ASD and the wide variety of treatments available to address many of those needs, there is still a great need for effective methods that promote the development of speech sounds and facilitate the production of those sounds in this growing population. While the primary aim of this RCT is to investigate the effects of AMMTversus a control intervention (SRT) on minimally verbal children with ASD and compare the two interventions to determine whether one is more effective than the other, this study also aims to examine whether baseline cognitive skills, speech praxis, joint attention abilities and/or neural architecture can predict the effects of treatment with AMMT or SRT in minimally verbal children with ASD.
The study is evaluating the efficacy of open-label placebo for the treatment of functional dyspepsia.
Irritable bowel syndrome (IBS) is a very common functional gastrointestinal disorder affecting nearly 20% of the North American population. IBS is characterized by chronic abdominal, associated with a change in bowel frequency and or consistency that lack a known structural or anatomic explanation. Current treatment for IBS is primarily symptom-based. However over a third of patients with IBS fail to respond to currently available therapies.
The prevalence of vitamin D deficiency/insufficiency is estimated in over a billion people world-wide . Vitamin D has potential mechanisms not only in the balance of calcium and bone homeostasis, but also a key modulator of the immune system. Vitamin D receptors (VDRs) are located on all nucleated cells including the GI tract. Thus far, there is already accumulating evidence for a role for vitamin D supplementation in inflammatory bowel disease (IBD). A recent systematic review suggested there may be benefits of vitamin D supplementation in IBD.
Vitamin D insufficiency is widespread in patients with IBS and there is a positive association between vitamin D status and quality of life. To date, there is no US trial examining the effect of vitamin d supplementation on IBS symptoms and quality of life in patients with IBS.
Cervical cancer is the leading cause of cancer death among women in Botswana. The burden of cervical cancer is largely related to the high prevalence of HIV in Botswana (22%), as HIV is known to be a significant risk factor for cervical cancer. Cervical cancer screening is life-saving and has been shown to reduce cervical cancer incidence in multiple settings. Yet, there is no consensus on appropriate screening algorithms for women living with HIV, across resource settings. Botswana is in a unique position, relative to its neighbors in Sub-Saharan Africa, in that there exists capacity for advanced screening modalities, including primary high risk human papilloma virus (hrHPV) testing and cytology-based screening. To address this issue, this study seeks to evaluate two-stage cervical cancer screening algorithms for women living with HIV in Botswana using hrHPV testing. The protocols include hrHPV testing followed by Pap Smear evaluation, VIA and colposcopy. These same participants will be invited back at one-year for cervical cancer screening using hrHPV testing (followed by triage testing) in order to inform guidelines on the frequency of HPV testing in women living with HIV. The evidence generated will be critical to guiding cervical cancer screening in HIV-infected women across resource settings.
This is a prospective pilot to investigate the effect of 3D printer customized CPAP masks on the comfort of patients with obstructive sleep apnea.
Investigators will assess the incidence and duration of postoperative delirium in patients ≥60 years old undergoing coronary artery bypass grafting (CABG), with/without valve surgery (aortic and/or mitral) based on different regimens for postoperative sedation and analgesia. Patients will receive either intravenous (IV) dexmedetomidine and IV acetaminophen or standard postoperative management using IV propofol with morphine or hydromorphone. The Confusion Assessment Method (CAM) will be used to assess delirium in these patients. Investigators also seek to compare postoperative (48 hours) analgesic requirements in patients with or without IV acetaminophen. Investigators will finally assess postoperative cognition in post-surgical patients up to one year post-discharge using a cognitive assessment scale.
This research study is comparing Dual-Energy Contrast-Enhanced Spectral Mammography (CESM) to MRI as a screening tool for breast cancer.
Currently medications injected intravitreally in previously vitrectomized eyes have a very short half-life due to enhanced clearance of the drug. The use of the Ozurdex (dexamethasone) implant may allow sustained levels of steroid delivery to patients with diabetic macular edema that have undergone prior vitrectomy. The sustained steroid levels may lead to improved central retinal thickness measurements and improved visual acuity.
The investigators will be using nocturnal normobaric hyperoxia therapy in patients with diagnoses of conditions related to retinal ischemia.
This study is designed to compare four currently used types of anesthesia used prior to intravitreal injection in order to evaluate the most effective method of anesthesia in reducing pain and discomfort associated with intravitreal injections.
Patients with Irritable Bowel Syndrome (IBS) often report more fatigue and sleep disturbances compared to their healthy counterparts and compared to patients with other GI disorders. This pilot study will evaluate the feasibility of a Brief Behavioral Treatment for Insomnia (BBT-I) in Irritable Bowel Syndrome. 40 participants will be recruited; 20 will receive 4 weeks of BBT and 20 will be assigned to a wait list control group (WLC). The primary aim of the current project is to assess feasibility of administering BBT-I to a sample of patients with IBS. Because behavioral sleep treatment has not yet been studied in IBS or any other GI population, this project will provide information about treatment adherence, recruitment, and effect sizes. Secondary aims include evaluating the impact of BBT-I on sleep quality and IBS symptom severity.
The purpose of this study is to assess magnetic resonance imaging (MRI) as a tool to track tumor growth for renal cell carcinoma while the participant is receiving clinical treatment therapy with sunitinib or pazopanib. An MRI is a sophisticated type of scan that uses powerful magnets to make clearer images or to focus on detailed medical information in the participants abdomen and pelvis. This imaging done for this study will use the ASL MRI technique that allows us to see blood flow changes which possibly may indicated tumor growth.
This study seeks to determine whether artificial sweeteners in the context of diet soda may alter the brain's response to food cues and thus impact appetite.
Research studies have shown a strong association between cancer and blood clots in the veins (also known as deep vein thrombosis). These blood clots can flow to the lungs (pulmonary embolism) which in severe cases may be life threatening. Studies have demonstrated that increases in microparticles may contribute to the development of deep vein thrombosis in cancer patients. The purpose of this research study is to see if rosuvastatin lowers the number of tissue factor bearing microparticles in the blood (TFMP). TFMP are small particles that are generated from different types of blood cells in the body. In people who have cancer, TFMP are thought to be generated from cancer cells and may represent a risk factor for deep vein thrombosis.
The purpose of this study is to evaluate the effect of a nutrient dense plant rich (NDPR) diet compared to a standard USDA diet on glycemic control, inflammation, and cardiovascular risk in individuals with type 2 diabetes and overweight/obesity.
The purpose of this prospective randomized clinical trial is to compare two currently accepted standard-of-care treatment strategies: Medical thoracoscopy as compared to instillation of intrapleural tissue Plasminogen Activator (TPA) and human recombinant Deoxyribonuclease (DNase) for the management of empyema or complex parapneumonic effusion (CPPE) in adults.
This is a randomized pilot study to characterize engraftment of a donor's microflora onto patients with Irritable Bowel Syndrome with diarrhea following fecal microbiota transplantation.
The purpose of this study is to examine the influence of sleep effectiveness on glucose and insulin metabolism in health and disease (prediabetes and type two diabetes).
We will monitor sleep effectiveness using the sleep spectrogram, obtain serial nocturnal blood glucose and insulin measurements, and assess the impact of pharmacologic enhancement [using eszopiclone (Lunesta), a medication that promotes stable sleep)] on glucose and insulin homeostasis.
We hypothesize that 1: Effective sleep is associated with enhanced insulin sensitivity, relative to ineffective sleep states, and 2: Enhancing sleep effectiveness using eszopiclone (Lunesta) improves 24-hour glucose metabolism in prediabetics and diabetics compared to baseline.
This phase II multi-centered, randomized controlled trial of mechanical ventilation directed by esophageal pressure measurement will test the primary hypothesis that using a strategy of maintaining a minimal but positive transpulmonary pressure (Ptp = airway pressure minus pleural pressure) throughout the ventilatory cycle will lead to an improvement in patient survival.
The purpose of this study is to understand how carotid endarterectomy (CEA) or percutaneous carotid angioplasty and stenting (CAS) affect memory and thinking resulting in improving or worsening of thinking or memory. There have been many studies on this subject, some finding that certain patients gain improvement in their brain function and others might get worse. The goal of this study is to discover which patients are more likely to have improved cognitive functioning. Carotid endarterectomy (CEA) and percutaneous carotid angioplasty and stenting (CAS) are not investigational and are an accepted treatment for your condition. In addition, subjects that choose not to undergo surgery will also be included in this study.
The purpose of the protocol is to assess how incentive spirometer data gathered via a smartphone platform can be utilized to improve participant adherence to prescribed incentive spirometer exercises in the post-operative period. Half of the participants will receive a standard of care incentive spirometer with a passive tracking device while the other half of the participants will receive a smartphone connected device and smartphone with an application that will encourage their use.
Alzheimer's Disease (AD) is characterized by amyloid-β (Aβ) plaque buildup and phosphorylated tau (p-tau) in the brain, as well as widespread neurodegeneration. The evidence suggests that both amyloid and tau play a critical role in AD and interventions that reliably and safely decrease the intracerebral burden of amyloid or tau could potentially be of marked clinical importance. Currently, therapeutic options are very limited and while there are pharmacologic interventions that transiently improve cognitive function, there are no treatments that alter disease progression. The current study seeks to use a novel therapeutic intervention that uses noninvasive brain stimulation to target amyloid in the brain. The investigators anticipate this will decrease the amyloid levels in the brain, as evidence by Positron Emission Tomography (PET) imaging.
The purpose of this study is to test a clinical Decision Aid that will help patients and providers determine if pre-exposure prophylaxis (PrEP) is the right decision. The Decision Aid will be tested in both clinical and non-clinical settings with 80 patient-provider dyads. The investigators hypothesize that the use of the Decision Aid will reduce patient decisional conflict. The investigators predict that it will increase patient and provider knowledge of and intent to initiate PrEP.
This will be a randomized double-blind placebo-controlled clinical trial that will accept all eligible consecutive patients undergoing elective Kalish bunionectomies. Patients will be randomized into either receiving ketorolac (30 mg IV dose intra-operatively followed by 10 mg orally every 8 hours for five days) plus standard of care or placebo plus standard of care. The purpose of this study is to evaluate the effects of ketorolac plus standard of care on post-operative pain control and radiographic osseous healing. Patients will be assessed for pain via a validated pain questionnaire and for delayed unions via a radiographic scoring system shown to have both high inter- and intra-observer reliability by a blinded board certified radiologist. Additional outcomes of bunionectomy procedures will also be evaluated including adverse events and time to regular shoe gear and activities.
The clinical syndrome of PSP responds poorly to all available forms of therapy used in Parkinson's Disease (PD). Currently, no effective treatment exists. Coenzyme Q10 in high doses has been shown to be a beneficial therapy in PD and might possibly be a beneficial therapy for PSP. This study will compare the efficacy, safety and tolerability of Coenzyme Q10 versus placebo in patients with atypical parkinsonian syndrome, progressive supranuclear palsy (PSP).
Influenza (the 'flu') is a common virus infecting approximately 5-20% of the population in the United States and causing as many as 500,000 deaths worldwide each year. Currently, there are only a few treatments for influenza infection and none of these target inflammation that can be caused by the virus. This study will test whether the anti-inflammatory effects of statins, a class of drugs most often used to treat high cholesterol, will decrease the severity of illness in patients who are infected with influenza by testing markers of inflammation in the blood and recording resolution of influenza illness.
The study aims are
to demonstrate the feasibility of recruiting and enrolling 10 subjects aged 55-75 planning to undergo sleeve gastrectomy and enrolling 10-20 (1-2 per surgical patient) matched subjects to the described intensive lifestyle intervention.
to collect preliminary data on the comparative effectiveness of the two interventions on physical function, weight loss, body composition, bone density and QOL.
The main purpose of this study is to understand how insomnia (compared to good sleep) may affect the response of the body to a repeated physiological challenge, such as inserting the hand in ice-cold water for several times in a row. In particular, the investigators are interested in the response of markers that can be associated with stress, such as blood pressure and stress hormones.
The purpose of this study is to determine if treatment using a medication (anastrozole/Arimidex), which lowers estrogen levels in the blood is better than placebo, a tablet that does not contain any active medication, when combined with testosterone replacement to treat reproductive and sexual dysfunction in men with epilepsy. Anastrozole, the medication that is currently under study, does not, at this time, have FDA approval for use for this indication.
The investigators are performing this study to determine if supplementation with calcium and calcitriol (vitamin D) before surgery decreases the rate of hypocalcemia (low calcium) after surgery.
Postoperative hypocalcemia (low calcium) is the most common complication after thyroidectomy. Symptoms range from numbness/tingling around the mouth and fingers to severe problems such as low blood pressure, irregular heartbeat, muscle cramps and uncontrollable muscle spasms.
The current standard of practice at Lahey for patients undergoing total thyroidectomy is to start Tums 1500mg three times daily and Calcitriol 0.25mcg twice daily immediately after surgery. Also current practice is for each patient to have their calcium and albumin levels checked at 8 hours and 24 hours after surgery. If the corrected calcium level drops below 8.5 or they exhibit symptoms of hypocalcemia the dose of the Tums and Calcitriol are increased per protocol. All patients must also follow up in 3-4 days to have their calcium and albumin levels rechecked.
The investigators propose to change the above standard practice at Lahey by making only one change. The investigators wish to start Tums and Calcitriol 5 days before surgery, as opposed to after surgery. This will be the only change to the current standard of care at Lahey.
The investigators hypothesize that initiating Tums and Calcitriol supplementation in the preoperative period will decrease the overall rate of postoperative hypocalcemia and its related symptoms. This will possibly decrease length of hospital stay, decrease cost, and prevent any serious complications associated with low calcium.
The main purpose of this study is to learn about the effects of repeated exposure to sleep disruption (3 cycles of sleep disruption, each consisting of three days in a row where sleep is shortened and disrupted, followed by a single night of recovery sleep) on inflammation, mood, and pain processing (experiences/perceptions of pain). Purpose of this research project is to understand the mechanisms of how sleep disruption may change mood and the experience of pain. Understanding those mechanisms is important to develop interventions that may help to reduce the effects of sleep disruption on mood and pain.
Our goal is to determine the acute effects of intranasal insulin on regional perfusion and cognition of older adults. We propose a pilot study to examine the effect of a single dose of intranasal insulin on regional vasoreactivity and cognitive functions in 30 subjects with T2DM and 30 healthy controls >50 years old using a double blinded, placebo-controlled, cross-over design.
Hypothesis 1: Intranasal insulin improves acutely regional perfusion and vasoreactivity in older patients with T2DM as compared with placebo and compared with the control group.
Hypothesis 2: Intranasal insulin improves cognitive functioning including attention, memory and executive function in diabetic patients as compared with placebo and compared with control group.
The main purpose of this study is to determine whether treatment with deferoxamine mesylate is of sufficient promise to improve outcome before pursuing a larger clinical trial to examine its effectiveness as a treatment for brain hemorrhage.
This study will test the hypothesis that human brown adipose tissue (BAT) can be activated using a β3-adrenergic receptor (AR) agonist. The efficacy of β3-AR agonist will be compared with cold exposure, which we have already shown can activate human BAT, as well as a placebo control.
The investigators hypothesize that treatment with the iron chelator, Deferoxamine Mesylate, improves the outcome of patients with brain hemorrhage.
The purpose of this study is to determine whether treatment with Deferoxamine Mesylate is of sufficient promise to improve outcome before pursuing a larger clinical trial to examine its effectiveness as a treatment for intracerebral hemorrhage.
The purpose of this study is to test the feasibility of a modification of CET (Cognitive Enhancement Therapy) to address symptomatic and functional difficulties associated with Clinical High Risk for Psychosis (CHR).
Cognition for Learning and for Understanding Everyday Social Situations (CLUES) is designed to improve cognitive functioning (e.g., memory, attention, planning, etc.) in order to improve school, work, and social functioning. CLUES includes the following:
Computerized cognitive remediation ("exercises") to improve cognition.
Social-cognitive skills group designed to teach participants to act wisely in social situations.
Individual coaching sessions designed to enhance translation of skills learned from computer exercises and the group into real life.
CLUES is based on Hogarty and Greenwald's Cognitive Enhancement Therapy (CET), which was designed for treating individuals with schizophrenia. Research on CET for individuals with schizophrenia has found that CET appears to have helped participants improve cognition and social and work functioning.
This study will investigate the feasibility of CLUES for young people who are showing signs of clinical risk for psychosis.
Part 1: Preliminary open label trial of CLUES (n=8) to examine preliminary evidence of target engagement (change in cognition and social cognition), to refine assessment and recruitment approaches, to further optimize the treatment manual, and to ascertain feasibility and tolerability.
Part 2: Preliminary randomized controlled trial of CLUES vs supportive therapy (ST) + computer games to explore preliminary evidence of efficacy of CLUES vs. the control treatment (n=30).
The Moderate Alcohol and Cardiovascular Health Trial (MACH15) is a multicenter, worldwide, randomized clinical trial of ~15 gm of alcohol daily versus abstention, using a balanced parallel design and single-blind assessment of all outcomes among approximately 7,800 participants aged 50 years and older with advanced cardiovascular risk. Intervention will average 6 years in duration with a common close-out date. Following recruitment and pre-screening, participants will attend a screening visit followed by a two-week abstention washout period, a baseline visit and randomization, and subsequent visits at 3 months, 6 months, 12 months, and then annually until close-out.
To evaluate the potential of a new imaging device, termed Optical Frequency Domain Imaging (OFDI), in the early diagnosing of pulmonary malignancies in the central airways.
Efficiency in the operating room can be difficult in long cases with multiple surgeons. We used a team based approach to develop an intraoperative pathway for microsurgical breast reconstruction with a deep inferior epigastric perforator flap.
