This is an open-label, non-randomized study. Volunteers will be vaccinated with the typhoid oral vaccine, Vivotif. Vivotif has been licensed by the Food and Drug Administration (FDA) for travelers to developing countries. Volunteers will also be asked to provide blood, saliva, and stool specimens over a follow-up time period of up to eight years. The specimens obtained in this clinical research study will be used to further the investigator's understanding of the protective immunological mechanisms that can be elicited systemically and may be applicable to other enteric pathogens.

In this study, we aim to develop and validate a noninvasive approach for quantifying and imaging energy metabolism, without contrast agents, on widely available clinical MRI scanners. Briefly, this technique allows specific and selective imaging of the energy metabolite phosphocreatine (PCr), in vivo and non-invasively. PCr is one of the predominant high-energy phosphates present in brain and muscle and one that is altered by common diseases. Although energy metabolism and PCr play a vital role in cellular homeostasis, there currently are no routine diagnostic tests to noninvasively quantify or map the distribution of PCr with clinically acceptable spatial resolution or/and scan time. Here, we demonstrate that the exchangeable guanidinium protons of millimolar concentration PCr can be exploited to detect it via the water signal in MRI with greatly enhanced sensitivity (molar signal) using chemical exchange saturation transfer (CEST) MRI, and its concentration can be quantified using an artificial neural network (ANN). This new technique, dubbed ANNCEST, allowed us to obtain a high-resolution PCr map on human skeletal muscle within 1.5 min, on a 3T clinical MRI scanner equipped with just the standard MRI setup. To put this in a larger perspective, energy metabolism is critical for cell viability and is altered by many common acquired and inherited diseases. ANNCEST is arguably the first to use widely available MRI scanners to noninvasively image tissue energy metabolism of PCr, and thus would have appeal to a broad readership of scientists and clinicians interested in neurology, muscular dystrophies and myopathies as well as cardiology, to name a few.

Many human diseases are characterized by their ability to alter existing metabolic pathways and interrupt cellular processes. Cancer exploits the Warburg effect and utilizes greater glucose than normal cells and within this process uses anaerobic respiration, leading to increased conversion of pyruvate to lactate. This can be exploited by hyperpolarized imaging. Hyperpolarized 13C MRI imaging is an approach that utilizes a stable isotope of Carbon (13C) linked to pyruvate. MRI spectroscopy is used in conjunction with hyperpolarized 13C pyruvate in order to temporally detect pyruvate and its conversion to lactate in-vivo, in order to visualize downstream metabolic (glycolytic) activity secondary to the Warburg effect, which should be useful in detecting and characterizing tumors of various types. Hyperpolarized 13C pyruvate MR imaging has not been tested in most cancers. In this preliminary survey, we will test the hypothesis that hyperpolarized 13C pyruvate MR imaging can be used to image various cancers. Read Less

Anxiety is prevalent in young children, under 7 years of age, with autism. Yet, few studies have examined anxiety interventions for this age range, and only one anxiety treatment study has included young children with cognitive and language delays. Anxiety treatment models utilizing cognitive-behavioral therapy (CBT), adapted for children with autism, are empirically supported in school-age autistic children. Further, preliminary evidence suggests CBT approaches may reduce intolerance of uncertainty (IU), a mechanistic construct that may contribute to the maintenance of anxiety in autistic children. This study seeks to address the existing gap in anxiety treatment by examining the feasibility and preliminary efficacy of a novel, telehealth CBT intervention, DINO Strategies for Anxiety and intolerance of Uncertainty Reduction (DINOSAUR), which targets both anxiety and IU in young autistic children.

The investigators project, RESONATE, aims to investigate why some children develop obesity. To do this it uses data on eating and eating-related behaviors, genetic and environmental factors, and brain structure and function. This data is collected in a sub-sample of RESONANCE, a large study of families of children from infancy through childhood. The results will lay foundations for the development of early interventions to prevent or treat obesity. Read Less

Snoring is a common problem caused by vibration of tissues in the throat region during sleep. Although snoring is sometimes dismissed as a minor nuisance rather than a medical disorder, several studies indicate that snoring can disrupt sleep quality of the snorer, as well as the snorer's bed partner. Snoring also might lead to problems such as dry mouth, bad breath, dental problems, and even cardiovascular disease. Current treatments for snoring include lifestyle modifications such as weight loss, side-sleeping, and avoidance of evening alcohol intake. In some cases, invasive surgeries, dental devices, or even CPAP are recommended for snoring. These interventions have mixed effectiveness and may be difficult to use. It may be possible to treat snoring by fostering nasal breathing, while avoiding mouth-breathing during sleep. Breathing through the mouth reduces the airway diameter and contributes to snoring. Several studies show that nasal breathing can reduce snoring volume and improve airflow. Recent studies have shown that covering the mouth during sleep with adhesive patches or tape can improve snoring volume without adverse effects. However, these studies were performed in a small number of patients and did not fully measure the impact of the intervention on sleep quality, sleep architecture, or the experience of the bed partner, who is often the overlooked "victim" of the snoring. In this interventional study, the investigators will examine the safety and efficacy of mouth tape for snoring, focusing on subjective and objective snoring/breathing metrics of both the snorer and bed partner. Snoring is sometimes also a sign of obstructive sleep apnea (OSA). If OSA is ruled out with a sleep study, patients are considered to have "simple" snoring. When OSA is mild (apnea hypopnea index 15), treatments can include the same interventions as snoring (e.g. weight loss, avoidance of alcohol, side-sleeping) or can be more aggressively treated with devices such as continuous positive airway pressure (CPAP). CPAP may be challenging to use, expensive, and associated with side effects such as mouth dryness and skin irritation. Alternative, inexpensive, and well-tolerated interventions are needed for mild OSA. For this reason, the investigators include patients with snoring and mild OSA in this study. Read Less
