We wish to investigate the role of a specific gene in visceral pain sensation and perception. This gene, Nav1.8 has a known change present in 10% of the population which may affect the way we feel inflammatory pain in the gut. This is an important symptom in inflammatory bowel disease (IBD). Some patients feel high levels of pain we would like to control, other patients feel little to no pain in the presence of very active disease, which can lead to dangerously under-treated disease. In this study, we will use healthy volunteers as well as IBD patients, and test their sensitivity using rectal balloon dilation.Research subjects will be asked to fast, skipping solid foods and opaque liquids for 6 hours before the testing. Usually this means skipping 1 meal. At the beginning of the study visit. they will use an over the counter enema to clear their rectum of any stool. Healthy control subjects that have never had a colonoscopy before and all IBD patients will undergo a very brief proctoscopy to either verify rectal health or check for any IBD disease activity. Healthy controls that have had a prior colonoscopy within the last 5 years will skip that prior step. Then a trained physician on the research team will insert a thin, lubricated tube into the rectum, which will be inflated to specific pressures. Most of these tests will be designed to measure any change in sensation, then the need to use the toilet, followed by urgent need or discomfort, and lastly the lower threshold of pain. Test subjects will be able to stop testing at any time, should they become too uncomfortable. The testing takes between 1 and 1 and a half hours, and volunteers are compensated $200 for their time.

To simulate abdominal pain, we use a thin tube placed in the rectum that inflates a small balloon to very precise and safe pressures. Our bodies interpret these pressures (in ascending order) as the need to go to the bathroom; first just a little, then with increasing urgency and eventually discomfort and pain. During these experiments, we only measure the lower threshold of pain, and stop immediately when you tell us to stop. We have significant experience using this approach and we have found it consistently informative while causing the least amount of discomfort possible. The whole thing takes about an hour and we’re paying volunteers $200 for participating. We'll ask that you skip a meal before the study visit, and perform an over-the-counter enema at the start of the visit.

Restrictive (vs liberal) fluid treatment strategy during the first 24 hours of resuscitation for sepsis-induced hypotension will reduce 90-day in-hospital mortality.

We are evaluating patients who have been infected with Babesia. Babesia is a blood parasite that is acquired from ticks. The number of cases seen in Pennsylvania every year has been increasing. We intend to evaluate the blood of patients acutely infected with Babesiosis and review for possible simultaneous co-infections. We will compare those infected patients with the blood of healthy individuals. The goal is to identify proteins in the blood of acutely infected patients that are specific for Babesia and also evaluate the prevalence of patient's who have contracted a co-infection from the tick vector that transmitted the Babesia infection. The identification of the specific bacterial/parasitic antigens could then be used to create rapid diagnostic tests and help clinicians increase awareness of these tick-borne diseases.

We will obtain basic demographic information and past medical history. We will obtain two 10ml samples of blood. The blood will then be stored and ultimately sent to Antigen Discovery, Inc for proteomic array screening.

The purpose of this study is to gain a greater understanding of healthcare workers’ knowledge of and perception of dysphagia in older adults. Study participants will fill out a survey/questionnaire in a single study session. This is expected to take 15-20 minutes.

You will be asked to complete a single, brief survey. It will take no more than 15-20 minutes.

The purpose of this research is to investigate the associations between depressive symptoms and inflammation. The researchers are studying how specific symptoms of depression (such as fatigue, sadness, impaired concentration, and loss of pleasure) are related to markers of inflammation, which is a key component of our immune system. Volunteers with depressive symptoms, as well as volunteers without depressive symptoms are needed for this research study. This study includes an online survey to determine eligibility and one in-lab visit. Participants who are eligible will be scheduled for one in-lab visit (2.5-3h for participants with depressive symptoms & 1-2h for participants without depressive symptoms), where they will be asked to answer surveys with questions related to depressive symptoms and complete a number of tasks (using an iPad and a touch screen phone) that measure thinking skills including attention, memory and reaction time. Participants will also undergo a single blood draw to assess inflammatory markers.

Participation will require one in person visit at the CRC that takes from 1 to 1.5 hours total where they will have their blood drawn, fill out surveys about their mood, and complete cognitive tests.

This trial will address the safety of withdrawing hydroxychloroquine (HCQ) in patients with systemic lupus erythematous who are 60 years of age or older. In this older population the benefits of HCQ are expected to decrease since disease activity decreases with advancing age. The study will test whether HCQ can be safely discontinued in stable/quiescent patients.

Participants will be in this study for about 1 year, during which time they will come to 7 visits in the research clinic. The first visit will take up to 2 hours and will include blood and urine sampling and completion of self-assessment questionnaires. Subsequent visits will take up to 1 hour. Participants will be randomized to receive either the active drug hydroxychloroquine or placebo. The treatment will be blinded to both the participant and the investigator. Diaries will be requested in which the participant keeps track of dosing of the study medication.

The purpose of the study is to test how social decisions are affected by possible risk of infection. We aim to examine how choices in a risky social decision-making situation can influenced by viewing images of infection threat (e.g., person with runny nose) vs. images of neutral scenes or other threatening scenes.

There will be one 90-minute in-person visit. Participants will be asked to have electrodes placed on their skin to record their physiological signals, answer questionnaires, and complete a decision-making task on the computer while looking at different images.

The reproducibility, reliability, and validity of saliva collection techniques is an important issue that needs to be addressed to achieve consistency in the emerging field of mitochondrial psychobiology. The objective of the current study is to increase scientific rigor by utilizing robust and well-controlled methods in the collection and testing of saliva samples. Given the non-invasive and convenient nature of saliva collection, it is likely that research using saliva-derived cell-free mitochondrial DNA (cf-mtDNA) will increase. Therefore, to ensure that the results obtained from the current study are trustworthy and meaningful, we are proposing a small, highly controlled randomized study design that will integrate three methods of saliva collection. The study will adopt a rigorous and systematic approach to data collection, analysis, and interpretation. Through the implementation of these methods, we seek to achieve a higher degree of accuracy and reliability in cf-mtDNA saliva-based measurements.

Each participant will be asked to collect 3 randomized saliva samples (i.e., one static Salivette®, one active Salivette®, and either a second active Salivette® or a passive drool) upon awakening for 10 business days. All collection materials be pre-labeled with the day, type of sample, and order to make it easy for participants to quickly and accurately deposit samples upon awakening. Once saliva samples are collected, participants will be asked to promptly return the samples to the provided plastic bag and store the bag in their at-home freezers. All samples will be stored there until the end of the 10-day study. After the saliva is returned to the freezer, participants will complete a short (3-5 min) morning survey on the provided mobile device which has been pre-loaded with the M2C2 application. The morning survey asks questions about sleep, morning outlook, and anticipatory stress and positive experiences. In the evenings, participants will be prompted (via banner notification on screen and audible beep) to complete a slightly longer (8-10 min) survey. This survey asks questions about the respondent’s daily experiences (stressors, mood, physical symptoms). Within the application, there are three brief, objective cognitive tasks. Upon completion of the 10-day protocol, respondents will return the mobile device and saliva samples. Participants may bring all saliva samples back to the lab during regular business hours, or they may schedule a time for a member of the study team to pick up the samples. Depending on the distance between the laboratory and the participant’s home, the need for ice packs will be assessed on an individual basis.

Wheezing is a common symptom of respiratory distress in infants and children. Infants who wheeze are at increased risk of being diagnosed with asthma, the most common chronic disease of childhood. This study aims to yield an objective measure of asthma risk using molecular markers obtained from saliva. Saliva miRNA (markers used in this study) levels will be measured using HiSeq technology. Refinement and validation of this measure in future large-scale studies could allow clinicians to accurately predict for families an infant’s risk of asthma and optimize medical management to prevent future hospitalizations.

If your child has a respiratory illness you will be asked to provide a saliva sample at one clinic visit. Six months after the initial encounter, you will be asked to do complete surveys designed to be done remotely at home.

We are experiencing global outbreak of coronavirus (COVID-19) recently. Millions of people are suffering and dying every day, in spite of putting our best efforts. We are doing this survey to understand people’s reaction to this situation. The survey will ask about your knowledge, practices and worries. Your response will help us to understand how to better control these situations. Your feedback is highly important to us, as we need to find out the best way to stop the disease from spreading and killing thousands of lives, and to reduce the stress among the population.

Adults recently diagnosed with SARS-CoV-2 infection who use a 4-day combined intervention of nasal washes with 1% baby shampoo solution and oral gargles with Listerine Antiseptic® will have a reduced SARS-CoV-2 viral load compared to those using nasal and oral washes with normal saline. This combined intervention should be acceptable, tolerable and safe in this population. To test this, we are conducting a trial comparing the efficacy of a number of washes in reducing the oral and nasal SARS-CoV-2 viral load amongst adults.

At their home, participants will perform three nasal and oral rinses per day for 4 days and self-swab the nose and mouth before and after each morning rinse to collect specimens under the guidance of a zoom visit. On the morning of the 5th day participants will also self swab the nose and mouth for a final collection specimen. Participants will answer questions on an app and online platform.

You will also complete questionnaires and be contact weekly by the study site.

The goal of treatment with fazirsiran is to prevent and improve the build up of these abnormal proteins that cause liver injury and fibrosis by shutting down the production of Z-AAT. Decreasing Z-AAT build up in liver cells is important, as this protein has been clearly identified as the cause of liver injury in AATD.In this study, fazirsiran is being compared with a placebo for patients with AATD LD. A placebo is a liquid like fazirsiran but does not contain any active ingredients.

You will visit the study site approximately 12 times for blood sampling, computed tomography (CT) lung densitometry, lung function tests, FibroScans, ultrasounds, liver biopsy, esophagogastroduodenoscopy (EGD) study drug administration, and questionnaire completion.

The purpose of this study is to collect long-term safety data and to assess the efficacy of STAR-0215 in subjects with Type I or Type II Hereditary Angioedema (HAE).

Participants will answer questions about your health, provide blood samples, undergo routine urine laboratory tests, receive the study drug, undergo electrocardiogram (ECG), complete questionnaires, undergo physical exams, and provide Hereditary Angioedema (HAE) attack information. Participants in this study will have 17, 18, or 23 in person visits and 4 or 9 remote visits (phone contacts) depending on the Dosing Regimen.

The purpose of this research study is to test the safety of the study drug, sebetralstat and to see if it can treat Hereditary Angioedema (HAE) at the time of an HAE attack and to determine how children's bodies absorbs, breaks down, and remove sebetralstat.

You and your child will be expected to attend all study visits, complete the HAE attack diaries to the best of your ability, and tell the study staff about changes to your child’s health, medications, and other medical treatments. Your child is expected to take the study medication as instructed and will allow study staff to draw blood.

The purpose of this clinical research study is to learn more about the use of the investigational drug, deucrictibant, for the treatment of HAE. Deucrictibant is designed to block the effects of bradykinin to avoid progression of attacks and lead to the resolution of attacks. In this study, the investigational drug is a soft capsule containing 20 mg of deucrictibant that you will take by mouth. There are already medicines available to treat the manifestations of HAE attacks, but these are injected either into a vein or under the skin. If you are currently on a stable dose of prophylactic treatment to prevent HAE attacks, you will be asked to continue using this at the same dose throughout the duration of the study.

You will need to come to the study site approximately four times. At two of these visits, you will have blood and urine collected. You will have vital signs collected, physical exams, vital signs, and EKG’s performed. You will need to treat two HAE attacks with the study drug, complete questionnaires on an electronic diary, and participate in telephone interviews with the study team.
