The purpose of this study is to learn about the safety and effects of ATM-AVI for the possible treatment of infections caused by a type of bacteria called gram-negative bacteria. The study medicine is a combination of an antibiotic, aztreonam (ATM), and another medicine, avibactam (AVI), which is used to help stop bacteria from being resistant to antibiotics. Antibiotics are medicines that fights bacteria and infections. The study will include newborns and infants up to 9 months of age who are admitted in the hospital. The study is conducted in 2 parts: Part A and Part B. In Part A, all participants will receive a single intravenous (injected directly into a vein) infusion of ATM-AVI. This is to study the safety and effects of a single amount. In Part B, all participants will receive multiple intravenous infusions of ATM-AVI as treatment for a possible or confirmed infection with gram-negative bacteria.

The purpose of the study is to test the hypothesis that functionally navigated repetitive TMS stimulations to the prefrontal cortex (PFC) modulate aberrant cortical electrical activities at PFC circuitry. The TMS location of the PFC site will be individually localized by the symptom-related functional connectivity between PFC and symptom related areas (such as the auditory and language processing cortex). The investigators predict that such modulation will correct abnormal activities in patients with schizophrenia, reduce symptoms, especially auditory hallucination, and improve working memory/sustained attention performance.

The purpose of this study is to learn about how well the 20-valent pneumococcal conjugate vaccine (20vPnC) works against radiologically-confirmed community-acquired pneumonia (RAD+CAP) due to the 7 new serotypes (types of a bacteria called Streptococcus pneumoniae that cause pneumonia) included in 20vPnC vaccine. This study is seeking participants who: - are male or female ≥65 years of age. - are hospitalized with physician suspicion of community acquired pneumonia (CAP). - have pneumonia confirmed with imaging like a chest x-ray Participants will be asked to provide demographic and medical history information, and to provide a urine sample that will be used to test for pneumonia caused by specific strains of a bacteria called Streptococcus pneumoniae. We will compare the proportion of participants who have pneumonia caused by specific strains of the bacteria Streptococcus pneumoniae and were previously vaccinated with 20vPnC with the proportion of participants who have pneumonia caused by something other than vaccine type Streptococcus pneumoniae and have been vaccinated with 20vPnC. Participants will actively take part in the study for about 1-2 days. Information on participant's illness and hospitalization details will be collected through day 30 of their hospitalization through medical chart review.

The Myelin Disorders Biorepository Project (MDBP) seeks to collect and analyze clinical data and biological samples from leukodystrophy patients worldwide to support ongoing and future research projects. The MDBP is one of the world's largest leukodystrophy biorepositories, having enrolled nearly 2,000 affected individuals since it was launched over a decade ago. Researchers working in the biorepository hope to use these materials to uncover new genetic etiologies for various leukodystrophies, develop biomarkers for use in future clinical trials, and better understand the natural history of these disorders. The knowledge gained from these efforts may help improve the diagnostic tools and treatment options available to patients in the future.

There is a fundamental gap in understanding the maternal and neonatal effects of antenatal corticosteroid (ACS) administration in women with threatened preterm birth (PTB) who have diabetes. Since the initial discovery of ACS for neonatal benefit in 1972, more than 40 randomized controlled trials have been performed evaluating its efficacy. However, none of these trials have included women with T2DM, and there is limited data among women with gestational diabetes. While ACS have been shown to reduce neonatal morbidity associated with PTB in non-diabetic women, the side effects of ACS (maternal hyperglycemia and fetal hyperinsulinemia) may mitigate the neonatal benefit of ACS in women with diabetes. Before neonatal benefit of ACS can be evaluated in this population, the first step is to optimize maternal glycemic control after ACS. Previous studies evaluating maternal hyperglycemia after ACS have been limited by small sample size, retrospective study design, or insufficient glucose data. Use of continuous glucose monitoring (CGM) in a randomized clinical trial provides a unique opportunity to overcome these challenges. Our long-term goal is to improve maternal and child health among women with diabetes as an independently funded clinical researcher. The research objectives of this proposal are to test the efficacy of three treatment strategies at achieving maternal glycemic control after ACS and evaluate the association between maternal glycemic control and neonatal outcomes. Our central hypothesis is that treatment with a continuous insulin infusion will improve maternal glycemic control, which is key to improving neonatal outcomes, but at the cost of less patient satisfaction and more health resource utilization. This hypothesis will be tested by pursuing the following specific aims: 1) Test the efficacy of three treatment strategies (addition of sliding scale insulin, up-titration of home insulin, and continuous insulin infusion) at achieving maternal glycemic control after ACS and 2) Quantify the association between maternal glycemic control after ACS and neonatal morbidity. Completion of these aims will determine the optimal strategy to achieve maternal glycemic control after ACS and inform a larger, multicenter trial to improve neonatal outcomes among women with diabetes and threatened PTB.
