Description

The goal of this study is to compare the characteristics of echocardiography and different monitoring devices in shock patients, the relationship of device parameters to biomarkers associated with shock, and determine if these any of these add clinical utility when predicting the cause of shock. We will perform a prospective, observational study of patients found to have shock physiology in the ED and follow them to determine the final shock category and ultimate outcomes.

Description

The purpose of this investigation is to evaluate how early biomarkers of infection and inflammation perform in identifying patients at risk for poor outcome in sepsis and septic shock.

Description

The purposes of the study are to 1) study alterations in the metabolomic profile of patients exposed to post-ischemic conditions and 2) study alterations in myocardial infarction size of patients exposed to post-ischemic conditioning.

Description

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.

Description

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.

Description

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.

Description

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.

Description

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.

Description

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.

Description

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.

Description

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.

Description

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.

Description

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).

Description

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.

Description

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.

Description

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.

Description

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.

Description

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.

Description

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.

Description

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.

Description

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.

Description

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.

Description

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.

Description

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).

Description

Description

Four aims were pursued: (1) Evaluate the effectiveness of video messaging on adolescent donor designations in comparison to a regionally-matched historical comparison group of adolescents; (2) Compare the differential effectiveness of three commonly-used donation messaging strategies (informational, testimonial, and blended) on donor designations; (3) Examine the impact of donation messaging on changes in secondary outcomes (donation engagement, knowledge, attitudes, beliefs, likelihood of donor designation, discussion with a parent) before and after video intervention; and (4) Assess the commitment of parents to follow their adolescent's donation wishes in the event of death. Our central hypotheses were that integrating donation video messaging into driver education classes would generate a higher proportion of donor designations compared to a historical comparison group and that blended video messaging (informational + testimonials) would yield a higher proportion of donor designations and more change in secondary outcomes.

Description

In this project the investigators aim to improve eating control and weight loss outcomes in patients undergoing LAGB with an innovative brain-based intervention. Specifically, the investigators will enhance the activity of the right inferior frontal gyrus, a core region of the brain circuit of inhibitory control, using transcranial direct current stimulation (tDCS).

Description

The purpose of the research is to identify the frequency and severity of adverse events related to atrial fibrillation that occur after discharge from hospital where the patient underwent cardiac surgery.

The Specific Aims of the proposed study are to:

Identify the predictors of postoperative atrial fibrillation after discharge from hospital.
Identify the frequency of readmission to hospital, or other resource use such as Emergency Department or outpatient visit, for the treatment or prophylaxis of postoperative AF and consequent stroke or bleeding outcomes.
Identify the risks for stroke, death and other morbidity in patients after cardiac surgery and the effect of postoperative AF upon subsequent stroke or bleeding outcomes.

Description

The investigators aim is to augment the current process for surgical consent for patients undergoing urogynecological procedures by incorporating visual media. We propose that visual media will be an effective and efficient addition to the standard of care in urogynecological consents and will improve patient understanding and satisfaction. Our randomized controlled trial will investigate the effect of standardizing the consent for three urogynecologic procedures (vaginal hysterectomy, robotic sacrocolpopexy, and sub-urethral sling) using visual media, on patients' understanding of, and satisfaction with, their procedure. Our primary outcome will be patient's knowledge score at the end of the pre-operative clinic visit, and secondary outcomes include patients' satisfaction, subjective understanding of their procedure, immediate pre-operative and post-operative knowledge, and number of post-operative encounters. Participants will be followed up to their post-operative clinic visit.

Description

Multiple agents have been studied to prevent radiocontrast nephropathy. One of these agents is N-Acetylcysteine. Previous trials to assess N-Acetylcysteine's efficacy in the prevention of contrast nephropathy have been promising. However, previous studies have limited applicability to the Emergency Department (ED) patient population for two reasons:

1) Many of the pretreatment strategies employed in these studies take several hours or even days to perform, which is not feasible in acutely ill ED patients.
2) Most of these studies were conducted in patients undergoing cardiac catheterization. This may be a very different population than patients in the ED undergoing abdominal or chest computed tomography.

The investigators wish to study the efficacy of N-acetylcysteine as an agent to prevent radiocontrast nephropathy in ED patients undergoing computerized tomography. The investigators propose a randomized, double-blind, controlled trial comparing saline hydration plus N-acetylcysteine versus saline hydration alone. The hypothesis of this study is that N-acetylcysteine with normal saline will be more effective than saline alone in the prevention of radiocontrast nephropathy.

Description

The purpose of this study will be to determine the correct dose of leptin, a natural hormone secreted by the fat cells, to give to people when they are fasting and also to determine whether giving leptin to a person when he or she is fasting will reverse the changes in hormone levels that occur with fasting.

Description

This study is being done to determine if there are differences in mood during the menstrual cycle among women with epilepsy who take various different antiepileptic drugs and women without epilepsy.

Description

We are studying how spine movement changes with age, and when people have vertebral fractures (cracks in the bones of the spine) or hyperkyphosis (a forward stooped posture).

Description

The main purpose of this study is to determine the feasibility and effects of a 6-month tai chi exercise program as compared to a 6-month group walking program and standard care for patients with COPD that have recently completed a pulmonary rehabilitation program.

Description

The transversus abdominis plane (TAP) block is a regional anesthesia technique where local anesthetic is injected into the neurovascular plane between the transversus abdominis and internal oblique muscles. The TAP block has been shown to provide postoperative analgesia following abdominal surgery.There are many methods to administer local anesthetic into the transversus abdominus plane to provide post-operative analgesia. The more prevalent method is for an anesthesia provider to inject local anesthetic into the plane using ultrasound guidance, before surgery or after the conclusion of surgery. Alternatively, a surgeon can administer the local anesthetic during the operation without additional time or expense using direct laparoscopic visualization. We propose to compare the two methods for non-inferiority, in the context of an established enhanced recovery after surgery (ERAS) program. Non-inferiority being established by no demonstrable difference in post-operative narcotic requirements and equivalent average pain scores.

Description

The purpose of the study is to test the hypothesis that the addition of routine viral load testing to the standard laboratory monitoring of HIV patients on first-line antiretroviral treatment (ART) in Vietnam will result in better clinical outcomes for patients.

Description

The purpose of this study is to investigate the effect of canagliflozin, a medication approved by the FDA for the treatment of type 2 diabetes, on body weight and metabolism in people with type 2 diabetes who are overweight or obese.

Canagliflozin lowers glucose levels in the blood by making the kidneys excrete, rather than absorb, glucose. Canagliflozin is also often associated with weight loss.

The study population will generally be type 2 diabetics, ages 18-75 years old, who are overweight or obese.

To compare the efficacy, safety and tolerability of Coenzyme Q 10 versus placebo in patients with atypical parkinsonian syndromes corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP) ).

Description

The purpose of this study is to monitor fracture risk associated with bone tumors in cancer patients.

Previous studies from our lab have suggested that it is possible to compute the mechanical strength of bones with tumors using computed tomography (CT) scans, which are like three-dimensional X-ray pictures of the affected bones.

The next step in determining the usefulness of this type of strength analysis is to see if we can accurately predict who is at risk for bone fracture and which patients are at high risk of fractures.

This non-invasive analysis may help physicians determine the best treatment to reduce the risk of an impending bone fracture in the future.

Description

The purpose of this study is to determine whether a non-painful, non-invasive, brain-stimulation technique called transcranial direct current stimulation (tDCS) combined with traditional physical-occupational therapy (OT) will improve motor function in patients with chronic stroke. The aim is to determine the effect of applying real (anodal and/or cathodal) - in a dual configuration - vs sham (pretend) tDCS to the motor brain regions on both hemispheres - in a dual configuration - to improve motor function in chronic stroke patients. Our research in normal subjects has shown that motor skills can be enhanced if tDCS is applied to the brain's motor region during motor learning. The effects after a single session of tDCS can last for up to 30 minutes, effects of multiple sessions (one session per day) can last for weeks. Furthermore, single sessions of tDCS applied to the motor regions in stroke patients have shown that improvements in motor functions can be seen and that effects may last for at least 30 minutes. Patients enrolled in this trial will be randomized to receive either real tDCS or sham tDCS in combination with PT-OT once a day for 5 days. Assessments will be done about 3 days and 7 days after the end of the experimental treatment by investigators who are blinded to the intervention. Patients are also blinded as to whether they are receiving real or sham tDCS. We hypothesize that real tDCS applied to the motor regions in combination with PT-OT results in a subsequent improvement in motor function of the recovering hand over sham tDCS in combination with PT-OT.

Description

The purpose of this study is to evaluate how the participant's disease (ovarian, primary peritoneal serous, fallopian tube, or papillary serous endometrial cancer) responds to additional treatment with Avastin (bevacizumab). Participants have already received Avastin as part of maintenance therapy for their cancer. Maintenance therapy is a medical therapy that is given to people to prevent a relapse. However, cancer may return after maintenance therapy. This research study hopes to determine whether additional treatment with Avastin will be effective in treating the participant's cancer.
