This clinical trial aims to confirm previous findings from a smaller study which demonstrated significant improvements in all symptoms among veterans with Gulf War Illness after one month on the dietary intervention. The main objectives of this study are: 1) to confirm previous findings of treatment response to the diet in a larger and more diverse group; 2) to examine how changes in the nervous system may be the reason for improvement; and 3) to identify markers which change in the blood after one month on the diet. Participants will have baseline measures collected and then will be randomized into the intervention or wait-listed control group, which they will follow for one month before being reassessed.

This project will test the accuracy of a novel diffusion-weighted magnetic resonance imaging (DWMRI) approach using a deep convolutional neural network (DCNN) to predict an optimal resection margin for pediatric epilepsy surgery objectively. Its primary goal is to minimize surgical risk probability (i.e., functional deficit) and maximize surgical benefit probability (i.e., seizure freedom) by precisely localizing eloquent white matter pathways in children and adolescents with drug-resistant focal epilepsy. This new imaging approach, which will acquire a DWMRI scan before pediatric epilepsy surgery in about 10 minutes without contrast administration (and also without sedation even in young children), can be readily applied to improve preoperative benefit-risk evaluation for pediatric epilepsy surgery in the future. The investigators will also study how the advanced DWMRI-DCNN connectome approach can detect complex signs of brain neuronal reorganization that help improve neurological and cognitive outcomes following pediatric epilepsy surgery. This new imaging approach could benefit targeted interventions in the future to minimize neurocognitive deficits in affected children. All enrolled subjects will undergo advanced brain MRI and neurocognitive evaluation to achieve these goals. The findings of this project will not guide any clinical decision-making or clinical intervention until the studied approach is thoroughly validated.

Esophagectomy is the cornerstone of the curative treatment of esophageal carcinoma. Despite this treatment, patients can suffer from locoregional or distant metastatic disease and only a very selected group of patients can be cured: mostly those with recurrence in one single organ. Brain metastases are rare after esophagectomy for cancer, but they have a serious impact on survival. Agressive treatment is often moren difficult for brain metastases compared to other metastases and some risk factors have been identified earlier. There is an impression that the incidence of brain metastases in esophageal cancer patients has increased since the introduction of neoadjuvant treatment schemes. However, this is not clear yet. A potential explanation could be that chemotherapy disturbs the blood-brain-barrier, hereby facilitating the migration of tumor cells to the brain. The purpose of this study is to retrospectively analyze the incidence and potential risk factors of brain metastases in patients who underwent esophagectomy for esophageal cancer. Patients treated between 2000 and 2019 will be included and outcome parameters are Odds Ratio for brain metastases (comparison between primary surgery and neoadjuvant treatment followed by surgery), time to recurrence and risk factors, number and characteristics of the brain metastases.

The aims of this exploratory research project are to customize, deploy and evaluate the preliminary efficacy of a socially assistive robot as a novel approach to motivate and encourage optimal, long-term use of new magnification devices for reading in individuals with vision loss. The goals are to promote patient acceptance, adherence and skills reinforcement to achieve proficiency in the use of the magnifier, in order to attempt to reduce visual disability while performing important daily activities, such as reading tasks. This is a high priority given the increasing prevalence of low vision, paucity of low vision rehabilitation providers, and barriers related to access to care, such as transportation and geography, all of which motivate the development of this complementary approach for the provision of additional support at home by the socially assistive robot.

The menopause transition is associated with a decrease in artery health and an increased risk for weight gain in storing fat in the stomach area which may increase the risk for heart disease. The purpose of this research is to study how the decrease in estrogen at menopause changes artery health and fat gain, and risk of disease in women as they age. The first aim in this study will determine whether short term and long term low estrogen levels in premenopausal women decreases artery function and whether this is related to an increase in fat in the stomach area. The second aim will determine whether the changes in artery health and body fat are related to changes in a pathway that breaks down an important amino acid called tryptophan. This pathway is thought to play a role in regulating the aging process. Therefore, the investigators will determine whether the decrease in artery health and the increase in body fat in the stomach region with low estrogen is related to changes in this pathway in the blood, in vascular cells and fat tissue. Because estrogen levels fluctuate in premenopausal women, the investigators will use an approach (intervention) that controls estrogen levels to address these aims. The investigators will use a medication that is typically used to treat endometriosis or uterine fibroids to lower estrogen levels and an estrogen patch to increase estrogen in some women. Some women will receive a patch that has no estrogen (called a placebo patch). The intervention period will be 20 weeks. The study will provide us with new knowledge on how low estrogen with menopause affects artery health and fat gain estrogen.

This is an inpatient four-arm randomized control trial comparing single drug clonazepam (S arm), a two-drug combination clonazepam/olanzapine (D arm), and a three-drug combination clonazepam/olanzapine/buprenorphine (T arm) with treatment as usual (TAU arm) in the treatment of emotional distress, specifically the Suicide Crisis Syndrome (SCS). All participants in experimental arms receive 2-day pulse treatments targeting four out of five of the acute emotional distress symptoms. The primary outcome measure is SCS at discharge and one-month follow-up. The secondary outcome measures include questions about suicidal behaviors associated with emotional distress at a one-month follow-up.

Turner syndrome (TS) is characterized by a missing whole or part of the second sex chromosome in a phenotypic female, resulting in short stature due to haploinsufficiency of the short-stature homeobox-containing (SHOX) gene. Growth hormone (GH) is an approved therapy for this condition, although not associated with GH deficiency, and benefits are modest. Vosoritide, a C-type natriuretic peptide (CNP) analog, targets chondrocytes within the growth plate leading to increased cell proliferation and hypertrophy. We hypothesize that patients with TS and short stature will respond to vosoritide treatment leading to increased growth velocity. This study will enroll pre-pubertal girls with TS who are either naïve to GH or have had a poor response to GH therapy. All subjects will be treated with vosoritide for 12 months and will be assessed for safety monitoring and improvement in height outcomes. Annualized growth velocity (AGV) on vosoritide will be compared to AGV in the 6-18 months prior to initiation of vosoritide based on historical data available in the medical record. Subjects with a positive response to therapy will be given the option to continue in the extension phase of the study during which they will continue to receive vosoritide until growth cessation.

The purpose of this study is to evaluate and optimize ultrasound and/or MRI hardware and software in both existing ultrasound/MRI units as well as in newly installed commercially available ultrasound/MRI units. The study also serves to familiarize the ultrasound/MRI technician staff with how to operate newly installed software sequences or hardware. The information obtained from this study will be utilized to optimize new software sequences and hardware that have been installed on the UMU ultrasound/MRI scanners. This will offer ultrasound/MRI technologists ample time to become familiar with the operation of new equipment. More specifically, the objectives of this study are to maximize contrast to noise (CNR) and signal to noise (SNR) ratios for new imaging sequences and hardware to obtain high quality images, maximize the potential of new machines and associated software/hardware to obtain the highest quality of images, and obtain the highest quality images in reasonable scan time to minimize patient motion.

The purpose of the Antiretroviral Pregnancy Registry (Registry) is to detect any major teratogenic effect involving any of the Registry drugs when administered to pregnant people. Registration is voluntary and confidential with information obtained from the health care provider. A Registry-assigned identifier allows for follow-up capability. Information on subjects is provided to the Registry prospectively (prior to the outcome of pregnancy being known) through their health care provider, with follow-up obtained from the health care provider after the outcome is determined. Providers are strongly urged to enroll their patients as early in pregnancy as possible to maximize the validity of the data. In addition, the Registry is very interested in assembling a group of providers who are willing to make a commitment to report all of their site's antiretroviral pregnancy exposures to the Registry, thereby assuring all cases can be considered prospective. Providers are encouraged to contact the Registry for more information about this group. The Registry is informed in its analysis by other data, for example, retrospective reports and clinical studies. Given the increasing number of medications and more aggressive approach to therapy, more HIV- and hepatitis B-infected people may be treated during pregnancy or become pregnant while under treatment. The paucity of data on use and infant outcomes of antiretroviral therapies during pregnancy makes this Registry an essential component of the ongoing program of epidemiologic studies of the safety of these therapies. Each year the Registry has enrolled approximately 1300-1700 pregnant people in the US exposed to antiretroviral drugs. This number represents approximately 15% of the 8,700 HIV positive people who give birth to live infants annually in the US.
