The overall goal of this project is to understand the mechanisms by which gastric bypass surgery improves glucose metabolism. The central hypothesis guiding this project is that the reconfiguration of intestinal transit with the Roux-en-Y will increase the release of insulinotropic GI hormones, termed incretins that improve insulin secretion and glucose metabolism. The study is divided into three specific aims. 1. To determine the role of incretin hormones on insulin secretion in patients with gastric bypass surgery using intravenous-oral hyperglycemic clamp. 2. To compare incretin effect and glucose tolerance among patient who suffer from hypoglycemia after RYGB and asymptomatic surgical and non-surgical individuals. 3. To quantify the contribution of GLP-1 to incretin effect enhancement following surgery.

RYGB (roux-en-y gastric bypass) has been reported to reverse type 2 diabetes (T2DM) immediately after surgery before any significant weight loss. In addition, a growing number of patients have been recognized with life-threatening hyperinsulinemic hypoglycemia several years following their surgery. While the mechanisms by which RYGB improves glucose metabolism or alters islet cell function in patients after RYGB are not understood, recent studies suggest that increased secretion of GI hormones, primarily glucagon-like peptide 1 (GLP-1), as well as alteration in neural activity may contribute to enhanced insulin secretion in general, and to a greater extent in patients with hypoglycemia. The proposed research is designed to address the role of RYGB on insulin secretion by evaluating the contribution of stimulatory factors (neural and GI hormone) on islet cell function and the islet cell responsiveness to the physiologic stimulatory factors, in RYGB patients with and without hypoglycemia and non-operated controls.

Pheochromocytomas and paragangliomas are neural crest-derived tumors of the nervous system that are often inherited and genetically heterogeneous. Genetic screening is recommended for patients and their relatives, and can guide clinical decisions. However, a mutation is not found in all cases. The aims of this proposal are to: 1) to map gene(s) involved in pheochromocytoma, and 2) identify genotype-phenotype correlations in patients with pheochromocytoma/paraganglioma of various genetic origins.

Premature rupture of membranes refers to the rupture of the fetal membranes prior to the onset of labor. Premature rupture of membranes is associated with a number of neonatal and maternal complications including an increased incidence of perinatal mortality and intra-amniotic infection. There is a need for improved diagnostic testing because of limitations of the current methods. PRO-MComplete is an immunochromatographic test that detects insulin growth factor binding protein 1 and alpha-fetoprotein in vaginal fluid as an indicator of membrane rupture.

Much has been learned about the efficacy and effectiveness of comprehensive healthy lifestyle interventions to reduce obesity. Few studies have been translated into rural settings or among Latinos. Y Living is an evidence-based family-focused intervention (FI) designed for urban Latino families. The FI is a 12-week behavioral modification program grounded in social cognitive theory, designed to engage the whole family in lifestyle changes by developing knowledge and skills in physical activity and healthy eating, building skills in goal-setting and self-monitoring, and creating a supportive home environment. Researchers will engage community partners in formative research to adapt the current FI for rural Latino families. Two parallel delivery methods of the FI will be developed and tested: 1) in-person group setting at a community center (FI-IP) and 2) home-based delivered remotely with technology (FI-RT). Both will be designed to address the unique social, cultural and environmental factors facing rural Latino families. The FI-RT will take advantage of innovative modern technology and e-Learning to increase program availability, accessibility and participation in rural settings. Researchers will conduct a 3-arm randomized controlled trial (RCT) to compare effectiveness of the two delivery approaches on weight loss (primary outcome) and energy balance behaviors (secondary outcomes) among obese Latino parent-child pairs versus control. The researchers will recruit 270 obese Latino adults (ages 21-65) with a child (ages 8-17) from three primary care practices in rural South Texas. These parent-child pairs will be randomized to one of three arms stratified by clinic: 1) FI-IP (n=90); 2) FI-RT (n=90); or 3) control group (n=90). Primary specific aims are to: 1) Conduct community-engaged formative studies to transform the existing FI into two unique delivery methods (FI-IP and FI-RT) for use in a subsequent RCT in a rural Latino community; and 2) Conduct a RCT to evaluate the comparative effectiveness of FI-IP and FI-RT to address weight loss (primary outcome) and energy balance behaviors (secondary outcomes) among obese rural Latino adults compared with adult participants in control group at immediate post intervention (3 months), after a 3-month maintenance program (6 months post randomization) and a 6-month follow-up (12 months post randomization). A secondary aim is to examine the impact of FI-IP and FI-RT children's weight and energy balance behaviors.

Purpose is to identify if misoprostol in addition to local vasopressin decreases blood loss when compared to vasopressin alone, which is our current practice at this time. The study will be double-blinded with neither the patient nor the researcher knowing whether the placebo or the misoprostol was given. We will monitor patients for decrease in hemoglobin and hematocrit, need for transfusion, and operative time among other measures of perioperative morbidity to see if the addition of misoprostol makes a significant difference. We will also observe patients to see if there are any side effects of misoprostol that make its use undesirable.

Current guidelines for the clinical management of acute spinal cord injury (SCI) recommend maintenance of mean arterial blood pressure (MAP) at 85 to 90 mmHg for the first seven days after SCI as a clinical option. Unfortunately, the medical evidence to support this recommendation exists only at the clinical case series level (Class III data). Furthermore, maintenance of sustained systemic hypertension, as per clinical guidelines, may be associated with risks to the patient via adverse medical events. Given this equivocal evidence, the investigators group has questioned the merit of sustained induced hypertension following acute SCI and has previously conducted a randomized, prospective controlled feasibility study to further examine this issue. This prior pilot study randomized patients with acute SCI to a spinal cord perfusion pressure (SCPP = MAP - intrathecal pressure (ITP)) target of ≥ 75 mmHg or to a control group (hypotension avoidance, MAP ≥ 65 mmHg). The primary endpoint measure was defined as the change in American Spinal Injury Association (ASIA) motor score from baseline. No difference in the primary outcome was noted at one-year post-SCI in this study. In light of this pilot data, the investigators hypothesize that maintenance of normotension (MAP ≥ 65mmHg) is not inferior to induced hypertension (MAP ≥ 85mmHg) for 7 days following acute SCI. As such, the investigators propose to conduct a Phase III non-inferiority prospective, randomized clinical trial in acute SCI patients. Subjects will be randomized into one of two MAP management groups for 7 days; Group 1 will be managed with a target MAP ≥ 65 mmHg, while Group 2 will be managed with a target MAP ≥ 85 mmHg. The primary endpoint will be change in ASIA motor score from baseline at 12 months post injury. A difference of ≤10 ASIA motor points change from baseline between groups will be considered as non-inferiority. Secondary endpoints will include ASIA sensory score, proportion of patients achieving a one grade improvement in ASIA impairment scale, quality of life assessment (as measured by Short-Form-36 [SF-36]) and functional outcome (as measured by the Spinal Cord Independence Measure (SCIM) and Functional Independence Measure (FIM). These will be measured at baseline, 72 hours and 3, 6 and 12 months from injury. Adverse events will be meticulously recorded. The information gleaned from this trial will provide valuable information for the acute treatment of traumatic SCI and will serve the objective of optimizing current clinical practice and thus maximizing medical and neurological outcome for individuals following acute traumatic SCI.

This randomized phase III trial studies how well doxorubicin hydrochloride and cyclophosphamide followed by paclitaxel with or without carboplatin work in treating patients with triple-negative breast cancer. Drugs used in chemotherapy, such as doxorubicin hydrochloride, cyclophosphamide, paclitaxel, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether doxorubicin hydrochloride and cyclophosphamide is more effective when followed by paclitaxel alone or paclitaxel and carboplatin in treating triple-negative breast cancer.
