The goal of this observational study is to investigate the development of vulvovaginal graft-versus-host- disease (GVHD), an under-reported and under-recognized manifestation of chronic GVHD. This study aims to characterize the vaginal microbiome in participants undergoing allogeneic hematopoietic cell transplantation (HCT). The main questions it aims to answer are: * Is the vaginal microbiome altered during allogeneic HCT? * What changes may help researchers understand the development of vulvovaginal GVHD? Participants will be asked to undergo an assessment of vulvovaginal symptoms through a vulvovaginal symptom questionnaire once pre-transplant, 6 months post-transplant, and twelve12 months post- transplant. Participants will also be asked to undergo a vaginal microbiome (collection of bacteria, fungi, and viruses that live on our bodies) evaluation through a vaginal exam performed by a gynecologist with collection of vaginal samples once pre-transplant and again six months post-treatment and twelve months post-transplant. If a participant develops symptoms of vulvovaginal GVHD at any point in time during the post-transplant follow up, the participant may partake in additional vaginal exams to diagnose GVHD at the time of symptom onset.
This study is open to people with hidradenitis suppurativa (HS) who have completed another study with spesolimab (study 1368-0098 (NCT05819398) or study 1368-0100). The purpose of this study is to find out how well people tolerate spesolimab and whether it helps people with HS in the long-term. For about 1.5 years, participants get spesolimab injections under the skin every 2 weeks. Participants are in the study for about 2 years. During this time, participants have 41 visits. 24 visits are done at the study site. 17 visits can be done by video call at the participant's home. At study visits, doctors check the severity of the participant's HS and collect information on any health problems of the participants.
Vaccine responses in patients treated with anti-CD20 antibodies (ocrelizumab and ofatumumab) or S1P receptor modulators (fingolimod and siponimod) were evaluated before and after third SARS-CoV-2 vaccination as part of an ongoing longitudinal study. Total spike protein and spike receptor binding domain (RBD)-specific immunoglobulin G (IgG) responses were measured by Luminex bead-based assay. Spike-specific CD4+ and CD8+ T cell responses were measured by activation-induced marker expression.
Ulcerative colitis (UC) is a type of inflammatory bowel disease (IBD) characterized by diffuse, continuous inflammation of the colon. This study will assess how safe and effective mesalamine delayed-release capsules are in treating pediatric participants with UC. Adverse events and change in disease activity will be assessed. Delzicol (Mesalamine) is an approved drug being developed for the treatment of Ulcerative Colitis (UC). Study doctors put the participants in 1 of 2 groups, called treatment arms. Each group receives a different treatment. Around 80 Pediatric participants aged 5 to 17 years with a diagnosis of UC will be enrolled in approximately 45 sites in the United States. Participants will receive oral mesalamine capsules twice daily for 26 weeks and followed for 30 days. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
The investigators propose to evaluate the use of a telemedicine tool, the TELE-ASD-PEDS (TAP), that is designed to assess for autism spectrum disorder (ASD) symptoms in toddlers. The TAP was developed at VUMC by a team of clinical psychologists with expertise in the early identification of ASD. The TAP has been studied in controlled laboratory settings, with high levels of family and clinician satisfaction, as well as excellent agreement with blinded comprehensive ASD evaluation. The TAP has also been used to complete direct-to-home telemedicine assessments during the COVID-19 pandemic. However, the investigators have not yet compared direct-to-home assessments using the TAP with gold standard, in-person ASD assessments. It has also not yet been studied in a diverse sample of families or with providers outside of VUMC. This study will allow the investigators to address those gaps.
Aim is to undertake a screening study that identifies undiagnosed patients with LSDs and determine the prevalence of these diseases with special focus on underrepresented minority groups.
Alcohol dependence is among the most common and costly public health problems affecting the nation. Among individuals with alcohol use disorder (AUD), those with (vs. without) a co-occurring anxiety disorder (AnxD) are as much as twice as likely to relapse in the months following AUD treatment. Dysregulation of biological stress-mood systems predict and correlate with AUD relapse and AnxD symptomatology. In contrast, stress system re-regulation correlates with improved AUD treatment outcomes but has not been examined with respect to AUD recovery and relapse in co-occurring AUD+AnxD.
Background: The field of nuclear medicine has changed a lot in the past decades. Technology has gotten better, so patients are exposed to less radiation. But now workers are doing procedures more often and using lead aprons less. So they may be exposed to more radiation. This may put them at higher risk for cancers and other health problems that are related to radiation. Researchers want to collect data from technologists to learn more about the risks and appropriate doses of radiation. Objective: To learn more about the risks and appropriate doses of radiation for nuclear medicine technologists. Eligibility: Adults who were first certified in nuclear medicine technology in the United States after 1980. They must be living in the United States. They must not be participants in the USRT study. Design: Participants will be recruited online. Participants will complete an online survey. It will take about a half hour. This will have questions about their work with nuclear medicine procedures. There will be questions about the kinds of procedures and how often they do them. Participants will give a short work history. This will include the names of current and past employers. Participants will allow researchers to get records of their film badge dose readings. These will come from dosimetry providers. Dosimetry data will not be shared with participants. Researchers can t ensure the how accurate or complete the data are.
This is a prospective, multi-center study examining the clinical impact of the Corus CAD (Age/Sex/Gene Expression score - ASGES) assay in approximately 250 evaluable subjects with no history of obstructive coronary artery disease who now present with chest pain or anginal-equivalent symptoms to a primary care physician (PCP) for evaluation.
Most bone marrow transplants for children with sickle cell disease are performed using high doses of two chemotherapy agents: busulfan and cyclophosphamide for the pre-transplant conditioning. This approach produces cure in most cases (approximately 95%). It, however, has serious side effects, including seizures and infertility. The primary goal of this study is to determine how much we can lower the dosages of busulfan and cyclophosphamide by incorporating fludarabine, a safer chemotherapy agent, into conditioning. The secondary goal is to develop a better understanding of how bone marrow transplants cause neurologic problems like seizures.
RATIONALE: Giving low doses of chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer or abnormal cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil before and after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well donor umbilical cord blood transplant with reduced intensity conditioning works in treating patients with advanced hematological cancer or other disease.
RATIONALE: Rasburicase may be an effective treatment for graft-versus-host disease caused by a donor stem cell transplant. PURPOSE: This clinical trial is studying how well rasburicase works in preventing graft-versus-host disease in patients with hematologic cancer or other disease undergoing donor stem cell transplant.
RATIONALE: Photodynamic therapy uses a drug that becomes active when it is exposed to a certain kind of light. When the drug is active, precancerous cells and cancer cells are killed. PURPOSE: This phase II trial is studying the side effects and how well photodynamic therapy with porfimer sodium works in treating patients with precancerous lesions, cancer, or other disease of the aerodigestive tract.

RATIONALE: Giving chemotherapy, such as clofarabine, melphalan, and thiotepa, before a donor stem cell transplant helps stop the growth of cancer or abnormal cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil before the transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the side effects and best dose of clofarabine when given together with melphalan and thiotepa, followed by a donor stem cell transplant and to see how well it works in treating patients with high-risk and/or advanced hematologic cancer or other disease.

The swelling of the gum, or periodontitis, is the leading cause for tooth loss, and currently affects up to 65 million adults only in the United States. One of the reasons for the widespread of periodontitis is because currently there are no definitive methods to detect the onset of gum disease. This lack of foresight impedes medical professionals to enact any preventive measures before the disease already manifests itself. We wish to expand our understanding towards the development of periodontitis by studying the expression and activity of salivary markers that have been associated with advanced stages of the disease, wherein the supporting tissues of tooth (periodontium) are already irreversibly destroyed. We hypothesize that a progressive shift in the expression of such salivary markers can indicate a change or evolution of periodontitis staging. In specific, we seek to establish a quantifiable relationship among levels of salivary proteases called MMPs, level of metal ions in different stages varying from health to periodontitis. The overall goal of this proposal is to enhance the predictability of periodontitis, as we are currently unable to diagnose the disease until the manifestation of its clinical signs and symptoms.
This study plans to enroll 10 patients aged 13-17 years of age with refractory perianal fistulizing disease. Patients will be treated by direct injection to the fistula tract(s) with 75 million allogeneic bone marrow derived mesenchymal stem cells at baseline and again after 3 months if not completely healed.
The immediate goal of this study is to collect biological samples (i.e., tissue and/or fluid), clinical information, and laboratory data from disease and non-disease subjects seen at Intermountain Healthcare affiliated facilities. The long-term goal is to annotate tissue and/or fluid biomarker data to clinical information and laboratory data for the purpose of improving health care delivery and prognostic potential.

Post-acute sequelae of SARS-CoV-2 infection can cause multiple system function disorders, and complicated symptoms last for an extended period. The virus can cause this continued infection, or the virus causes immune system function disorder and post-infectious autoimmune disease. The clinical symptoms can be smell loss, taste loss to liver function disorder, kidney function failure, different. No matter how complicated the systems showed in the clinic, all of the symptoms are due to the specific cells being damaged. Our clinical study is focused on recovering the damaged structure and function of the cells that could restore the organ function back to normal or close to normal
The research is being done to study the immune responses to COVID-19 vaccination in patients with rheumatic diseases.
