Type 2 diabetes (T2D) predisposes individuals to neurodegeneration and dementia, including Alzheimer's Disease (AD); yet the link between metabolic and neurodegenerative disorders remains unknown. Here, the investigators will study a well-defined human population with increased prevalence and early onset of both T2D and AD, individuals of Mexican descent living in South Texas. The study will begin to explore the possibility that disruption of the structure of the bacterial community residing in the gut in type 2 diabetic individuals of Mexican descent living in South Texas is directly related to the increased prevalence of early onset AD in this population. In this study, the investigators will perform gene sequencing on DNA isolated from fecal samples to identify and compare the populations of bacteria living in individuals with T2D versus non-diabetic controls. The investigators will analyze the findings to determine if the community structure of the gut microbiome of individuals of Mexican descent with T2D is significantly altered compared to that of non-diabetics within the same population. The investigators' findings could lead to the identification of early indicators of dementia onset as well as novel therapies for treating metabolic and neurodegenerative diseases.

Nearly half of women have obesity and/or hypertension (HTN). Specific to women, pregnancy creates a vulnerable window for excess gestational weight gain (GWG), exacerbating intergenerational risks for obesity, HTN, type 2 diabetes (T2D), and cardiovascular disease (CVD) across the lifespan. Healthy lifestyles are the first-line recommendations for prevention and treatment of overweight/obesity, HTN, T2D, and CVD. The Diabetes Prevention Program (DPP) is a well-established, Centers for Disease Control and Prevention (CDC)-led public health program focusing on healthy lifestyle changes and is effective at reducing 5-7% of body weight, lowering risks for T2D. Interestingly, research investigating the DPP as a lifestyle intervention for other chronic conditions (i.e., overweight/obesity and HTN) is lacking, demonstrating a missed opportunity. The aim of this study is to determine the initial effects of the first 6-months and after receiving the full 12-months of the virtual DPP compared to the DPP expanded with a CDC-approved HTN prevention component (DPP+) on physical activity, diet, weight, and CVD risk factors in 30 prediabetic women (18-45 years old) with a history of excess GWG, overweight/obesity, and HTN. Participants will be recruited through University of Texas Medical Branch (UTMB) community-based clinics using Epic. The Participants will be randomized into 2 groups (DPP and DPP+) and guided through the 12-month virtual DPP or DPP+ program using UTMB DPP personnel.

This phase III trial studies how well vitamin D3 given with standard chemotherapy and bevacizumab works in treating patients with colorectal cancer that has spread to other parts of the body. Vitamin D3 helps the body use calcium and phosphorus to make strong bones and teeth. Drugs used in chemotherapy, such as leucovorin calcium, fluorouracil, oxaliplatin, and irinotecan hydrochloride, work in different ways to stop the growth of tumor cells by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as bevacizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving vitamin D3 with chemotherapy and bevacizumab may work better in shrinking or stabilizing colorectal cancer. It is not yet known whether giving high-dose vitamin D3 in addition to chemotherapy and bevacizumab would extend patients' time without disease compared to the usual approach (chemotherapy and bevacizumab).

Preterm premature rupture of membranes (PPROM) complicates 4% of pregnancies annually. This pregnancy complication is a major contributor to preterm births and results in neonatal morbidity and mortality. The current standard of care for PPROM subjects between the gestational age of 24 weeks and 0 days and 33 weeks and 6 days, is to administer ampicillin and erythromycin for a total of 7 days. Erythromycin can cause GI upset and some subjects do not tolerate this regimen over the course of 7 days. In addition, there is a national shortage of erythromycin, and published expert opinion proposed to use a second-generation macrolide (azithromycin) instead of erythromycin. Azithromycin can be taken once daily, is cheaper than erythromycin and has less GI upset adverse effects. The investigators' objective is to compare the effectiveness of the 2 regimens in prolonging pregnancy after PPROM. The investigators' working hypothesis is that there is no measurable difference in the primary outcome between the group randomized to the azithromycin regimen versus the group randomized to the erythromycin regimen.

This phase Ib trial studies side effects and best dose of copanlisib and olaparib when given together with durvalumab, and how well they work in treating patients with solid tumors that have spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). Copanlisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving combinations of copanlisib and olaparib or copanlisib, olaparib, and durvalumab may work better in treating patients with solid tumors compared to usual treatments such as surgery, radiation, or other chemotherapy drugs.
