Similar to the paradigm established in other hematologic malignancies that are considered curable, the achievement of MRD(-) status is necessary for long term disease control in MM. The fact that the majority of patients remain MRD (+) after induction therapy and AHCT points to the opportunity to deploy novel agents with complementary mechanism of action and favorable toxicity profile to reach and maintain MRD (-) status. Given its favorable toxicity profile, the convenience of oral administration, and compelling single agent activity even in heavily pretreated MM, iberdomide is likely amenable to long term therapy in patients with high-risk of relapse/progression identified by the persistence of MRD(+). The investigators intend to develop combination(s) of iberdomide with other agents with complementary mechanism of action in the consolidation setting post AHCT in order to achieve and sustain MRD (-).

Acute stroke systems of care should emulate trauma systems which deliver the full range of care to all injured patients by means of organized, coordinated efforts in defined geographic areas. Just as trauma systems have proven ability to save lives of the most severely injured patients, clinicians should have a stroke system able to provide care to patients with the most severe strokes. The most severe type of acute ischemic stroke is due to proximal large vessel occlusion (LVO). Mechanical thrombectomy (MT) offers an extraordinary potential to improve the outcome of patients with LVO. Unfortunately, in part because MT is available only at advanced stroke centers, only a minority of patients with LVO are treated with MT, and there are racial, socioeconomic, and rural disparities in access to MT. Based on the success of trauma systems and our prior collaboration, the Alabama Department of Public Health (ADPH) is planning a five-year statewide quality improvement initiative of trauma communications center (TCC) coordinated severity-based stroke triage (SBST) which aims to transform the fragmented acute stroke care system by coordinating prehospital and inter-facility emergency stroke care.

The goal of the Molecular Transducers of Physical Activity Consortium (MoTrPAC) is to assess molecular changes that occur in response to physical activity (PA). To achieve this aim, a mechanistic randomized controlled trial (RCT) is conducted, in which adult study participants are randomized to endurance exercise (EE) training, resistance exercise (RE) training, or no exercise Control for a period of approximately 12 weeks. The overarching hypothesis is that there are discoverable molecular transducers that communicate and coordinate the effects of exercise on cells, tissues, and organs, which may initiate processes ultimately leading to the health benefits of exercise. Because this is a mechanistic trial, the main goal is not a single health-related outcome. Rather, the goal is to generate a resource leading to the generation of a map of the molecular responses to exercise that will be used by the Consortium and by the scientific community at large to generate hypotheses for future investigations of the health benefits of PA.

Obstetric anal sphincter injuries (OASIS) cause significant morbidity and are well known risk factors for sexual dysfunction, urinary and anal incontinence. Postpartum and breastfeeding are relative hypoestrogenic states with risk factors for dyspareunia and vaginal atrophy. Estrogen deficiency results in changes in the vaginal epithelium and poor tissue quality which results in poor wound healing. For postmenopausal women with vaginal atrophy undergoing surgery for pelvic organ prolapse, early administration of topical vaginal E2 therapy resulted in improved markers of tissue quality. Currently, there are limited studies to reference for proposed treatment modalities to improve sexual function and incontinence in this population. In this proposed randomized, placebo-controlled trial, women who sustain OASIS will be recruited and randomized to begin intravaginal estrogen therapy or placebo at their 2-week follow-up visit after hospital discharge. Participants will complete validated questionnaires relating to sexual function and pelvic floor disorders (urinary and anal incontinence) symptom distress and impact. The primary outcome of this study will be sexual dysfunction symptom severity measured by the female sexual function index (FSFI) at 6 months postpartum. Secondary outcomes will be urinary and anal incontinence distress and impact measured by St. Mark's score and the fecal incontinence quality of life (FIQOL) questionnaire for anal incontinence and urogenital distress inventory (UDI-6) for urinary incontinence. The objective of this study is to determine if intra-vaginal estrogen therapy improves sexual function and incontinence symptom distress and impact for postpartum women after OASIS.

GDM is characterized by decreased insulin sensitivity, decreased insulin secretion, or a combination of both. Women with GDM are at significant risk for overt T2DM later in life, and postpartum insulin sensitivity and secretion in women with GDM has not been quantified, limiting our ability to optimize screening for overt T2DM. In addition, compliance with currently recommended postpartum T2DM screening by OGTT is poor. Quantification of postpartum insulin sensitivity and secretion in women at high risk for T2DM will inform strategies to improve diagnostic strategies. Continuous glucose monitoring (CGM) is a new technology that may be useful to identify women with persistent hyperglycemia. Understanding maternal glycemia and physiology that drives glycemia in the postpartum period is limited. Completion of this study will define postpartum maternal glycemia, quantify insulin secretion versus insulin sensitivity defects, and demonstrate the feasiblity of using continuous glucose monitoring to identify women most at risk for overt T2DM.

The proposed study design is a single arm Phase II trial to document the feasibility of carboplatin-mirvetuximab - in patients with advanced-stage EOC. Patients with biopsy confirmed, newly diagnosed, advanced-stage serous EOC deemed appropriate for NACT will have their tumors evaluated for FRα receptor over-expression via a centralized immunohistochemical assay (IHC) and identified as appropriate for study participation if IHC staining is PS2+ in >75% of cells (40% of all serous patients). Eligible patients will receive NACT with one cycle of carboplatin, followed by mirvetuximab + carboplatin (if FRα +) every 21 days for three cycles prior to interval cytoreductive surgery (iCRS). A total of 70 will be included in the study. Following completion of 4 cycles total of NACT and after allowing for appropriate recovery of cycle # 4, patients eligible for surgery, will undergo an iCRS. Patients will then complete 3 more cycles of mirvetuximab + carboplatin for a total of 7 intended cycles of treatment. It is up to the treating physician if they want to add bevacizumab to the last 2 cycles or use any type of maintenance therapy. The decision to add bevacizumab or use maintenance therapy does not need to be made upfront. Patients will sign a screening consent form prior to tissue biopsy. If a patient is found to be FRα negative, their treating physician can select the treatment they deem appropriate and the patient will be declared a screen failure. Patients with BRCA mutations are not excluded from this trial and are allowed to receive standard of care maintenance therapy including bevacizumab and/or PARP inhibitors.

Non-encapsulated (free) heme, a breakdown component of hemoglobin, is associated with oxidative stress and inflammation with consequent cellular and tissue injury (Ryter & Tyrrell, 2000) (D T G Wagener, et al., 2001). Cardiopulmonary bypass is known to cause trauma to cellular components of the blood, to trigger an inflammatory response, and alter the rheology of the circulation. Prior research has demonstrated an increase in levels of free heme with cardiopulmonary bypass (Wetz, Richardt, Schotola, Bauer, & Bräuer, 2017) (Kubota, Egi, & Mizobuchi, 2017). The stress response to cardiac surgery and utilization of blood salvage techniques independent of cardiopulmonary bypass may affect plasma free heme levels as well as regulation of heme metabolism pathways. It is unclear whether and to what degree plasma levels of free heme may vary at discreet time points in the perioperative period during cardiac surgery involving both cardiopulmonary bypass and "off-pump" techniques. This is an observational, prospective cohort study in which we will assess for red blood cell trauma, free heme levels, and biomarkers for acute kidney injury at various time points throughout cardiac surgery. Urine and arterial blood samples will be collected at our routine, standard of care time points pre-, intra-, and post-operatively and in addition to the standard clinical tests that will be performed (arterial blood gas analysis and activated clotting time) several additional serum biomarkers will be analyzed. Clinical correlation will be performed with levels. Sub-analysis will be performed on the basis of off vs. on pump CABG cases and also in patient that do/not develop AKI post-operatively.
