Knee osteoarthritis (OA) is the most prevalent form of arthritis, a significant cause of disability in the U.S. With an aging population and the rise in obesity rates, the prevalence of knee OA is expected to climb, significantly reducing quality of life (QOL) for those suffering from this debilitating condition. Current national efforts to reduce analgesic utilization highlight the critical need for safe, effective, and accessible alternatives for pain relief. Low-carbohydrate diets (LCDs) reduce inflammation and pain independent of weight loss, indicating that diet interventions offer a non-pharmacological complementary treatment. However, differences exist in metabolism that are rarely addressed in diet intervention studies. Thus, it is important to assess the potential of different diets in a broad population of chronic pain sufferers to determine the potential of diets to reduce knee OA pain. We have shown that a LCD was associated with reduced evoked knee OA pain, daily pain and oxidative stress when compared to either a USDA diet or a diet-as-usual control. Both experimental diets reduced weight to a similar degree, arguing that diet quality was likely the key factor in pain reduction, as opposed to weight loss. However, previous studies comparing diets have utilized diet prescriptions with less control for adherence to the diets. To overcome this obstacle, and in line with our recent work, we will provide all snacks and meals during the diet intervention to increase adherence and retention in the study, allowing for better control over diet interventions and consistency of foods within each study group. We will recruit adults with knee OA (N=200) to complete our two-phase protocol. Phase 1 will involve a 1-week diet run-up that will allow for quantification of pain measures, psychosocial variables (socioeconomic status, nutritional knowledge, proximity to grocery stores, food insecurity), and diet quality to provide a baseline for comparison. Phase 2 will be a 6-week randomized diet intervention (LCD or USDA diet) in which both groups will be provided with all meals at the direction of study personnel and input from participants. Evoked pain tasks, measures of pain disability, severity, catastrophizing, and interference will be assessed every 3 weeks in addition to QOL measures, mood, and depression. Physiological variables will be assessed through blood draws (inflammatory profile) and dual-energy X-ray absorptiometry scans (DXA; body composition, visceral fat) at the end of Phases 1 and 2. This will be the first study to examine the efficacy of these diets to reduce knee OA pain with an emphasis on interactions with biopsychosocial variables. Changes in all pain measures following Phase 2 will be assessed with respect to published measures of clinically-meaningful differences in pain and disability, as well as for statistical significance. The central hypothesis is that the LCD will improve pain and QOL in participants with knee OA more than the USDA diet, but that both will be beneficial. Specific Aim 1: To investigate the efficacy of the diets to reduce pain and improve QOL. Hypothesis 1: The LCD group will show significantly greater reductions in: a) self-reported pain (>1.7 in pain intensity) and, b) evoked pain (>30%) when compared to the USDA diet. Hypothesis 2: The LCD group will show greater improvements in: a) QOL, b) mood, and c) self-reported improvement (>50% participants reporting "much improved" or "very much improved"). Hypothesis 3 (secondary): Both diets will result in improved pain disability, severity, catastrophizing and pain related fear; the LCD will outperform the USDA diet. Specific Aim 2: To explore individual differences in diet and baseline measures. Hypothesis 1: Baseline diet quality will be negatively associated with baseline pain sensitivity Hypothesis 2: Those reporting greater a) food insecurity and/ or b) proximity to grocery stores will report poorer-quality diets. Specific Aim 3: To determine whether physiological variables contribute to diet effects or lack thereof. Hypothesis 1: Baseline physiological measures (inflammatory profile) will predict: a) pain sensitivity, and b) reductions in pain. Hypothesis 2: Change in physiological measures (inflammatory profile, adiposity, leptin) will be related to: a) change in pain measures, b) change in QOL, c) self-reported improvement and, d) mood.

Although extensively studied, the cause of preeclampsia remains uncertain other than it is thought that the placenta plays a critical role in the development of preeclampsia. Recent data revealed that exosomes released from the placenta could cause preeclampsia by transporting specific cargo responsible for the pathophysiological changes associated with the systemic disease. By isolating these exosomes from maternal blood and placental tissue in patients diagnosed with preeclampsia and studying their biochemical, cellular and molecular mechanism in an animal model, the investigators hope to elucidate the critical role that exosomal cargo plays in the development of preeclampsia and cardiovascular remodeling. This will be accomplished by obtaining patient samples from volunteers delivering at the Women and Infants Center and taking the samples to the lab for quantification, characterization, and identification of key functional roles through in/ex vivo, in vitro, and profiling studies. The investigators believe this work will be valuable as hope exists to define the functional role exosomes play in the development of preeclampsia that leads to cardiovascular remodeling. Data from this study will shed more light on the functional role of exosomal cargo in normal and pathological pregnancies and point towards novel therapeutic intervention strategies for preeclampsia associated with cardiovascular disease.

The purpose of this study is to assess sense of control and catastrophic symptom expectations as targets for Retraining and Control Therapy (ReACT- an intervention focused on changing behaviors and thoughts) for treatment of adult psychogenic non-epileptic seizures (PNES, episodes resembling epileptic seizures but with no correlated epileptiform activity). 19 years and older participants diagnosed with PNES who are treated at UAB FND clinic will engage in twelve sessions of ReACT. Participants will be randomly assigned to one of three conditions: no wait, 3-month waiting period, 6-month waiting period. Sense of control over actions will be measured by the magic and turbulence task, a well-validated measure of sense of control. Participants will complete the cold pressor test (CPT) in which participants hold their hand in cool water for as long as possible up to 3 minutes. Catastrophic symptom expectations in response to the CPT will be measured by Pain Catastrophizing Scale (PCS), pain tolerance (time with hand in water) and cortisol response. Target assessments occur 7 days before treatment and 7 days after the 12th treatment session. Participants randomized to the 3-month and 6-month waiting period will also complete these measures one additional time immediately before the beginning of their waiting period. Long term follow-up assessments will occur at 2 months, 6 months and 12 months after the 12th treatment session. PNES frequency will be measured from 30 days before to 12 months after treatment. Participants randomized to the 3-month or 6-month waiting period conditions will log weekly PNES episodes until the start of therapy.

In 2014, a team of parents, nurses, and physicians created Patient and Family Centered I-PASS (PFC I-PASS), a bundle of communication interventions to improve the quality of information exchange between physicians, nurses, and families, and to better integrate families into all aspects of daily decision making in hospitals. PFC I-PASS changed how doctors and nurses talk to patients and families on rounds when they're admitted to the hospital. (Rounds are when a team of doctors visit patients every morning to do a checkup and make a plan for the day.) Rounds used to happen in a way that left out patients and families. Doctors talked at, not with patients, used big words and medical talk, and left nurses out. PFC I-PASS changed rounds by including families and nurses, using simple non-medical words, and talking in an organized way so nothing is left out. When PFC I-PASS was put in place in 7 hospitals, patients had fewer adverse events and better hospital experience. But it didn't focus on how to talk with patients with language barriers. This project builds upon upon PFC I-PASS to make it better and focus on the special needs of patients who speak languages other than English. This new intervention is known as PFC I-PASS+. PFC I-PASS+ includes all parts of PFC I-PASS plus having interpreters on and after rounds and training doctors about communication and cultural humility. The study team will now conduct a stepped-wedge cluster randomized trial to compare the effectiveness of PFC I-PASS+ and PFC I-PASS to usual care at 8 hospitals.

Advancements in prenatal genetic screening have significantly improved the identification of chromosomal abnormalities and heritable conditions during pregnancy, yet current standards for patient education in this domain are largely ineffective. The most effective approach to education about prenatal screening is one-on-one genetic counseling, but due to the limited number of counselors this is not feasible, especially in rural and frontier areas. The investigators will address this national problem using a novel education game that can more effectively address this gap in healthcare decision-making.

The goal of the current pilot clinical trial is to evaluate the safety and tolerability of pirfenidone in patients with predicted moderately severe and severe acute pancreatitis. Pirfenidone is currently approved by FDA for the treatment of idiopathic pulmonary fibrosis. Now, over 5 years of data has accumulated demonstrating safety of its use in humans. The investigators' preclinical data suggest that pirfenidone is very effective in reducing the severity of acute pancreatitis in animal models. Following are the objectives of the proposed clinical trial: Primary Objective: - To evaluate the safety and tolerability of pirfenidone, compared to placebo, in patients predicted to have moderately severe or severe AP. - To evaluate the efficacy of pirfenidone in reducing the laboratory markers of inflammation and improving patient reported outcome measures. Secondary Objective: - To evaluate the efficacy of pirfenidone in reducing the severity of acute pancreatitis, as measured by well-defined endpoints.

The APOLLO study is being done in an attempt to improve outcomes after kidney transplantation and to improve the safety of living kidney donation based upon variation in the apolipoprotein L1 gene (APOL1). Genes control what is inherited from a family, such as eye color or blood type. Variation in APOL1 can cause kidney disease. African Americans, Afro-Caribbeans, Hispanic Blacks, and Africans are more likely to have the APOL1 gene variants that cause kidney disease. APOLLO will test DNA from kidney donors and recipients of kidney transplants for APOL1 to determine effects on kidney transplant-related outcomes.

The rare histiocytic disorders (RHDs) are characterized by the infiltration of one or more organs by non-LCH histiocytes. They can range from localized disease that resolves spontaneously, to progressive disseminated forms that can be sometimes life-threatening. Since they are extremely rare, there is limited understanding of their causes and best treatment options. Physicians, patients and parents of children with RHDs frequently consult members of the Histiocyte Society regarding the best management of these disorders. Very often, no specific recommendation can be made due to the lack of prospective outcome data, or even large retrospective case series. The creation of an international rare histiocytic disorders registry (IRHDR) could facilitate a uniform diagnosis of the RHDs, as well as the collection and analysis of the clinical, epidemiological, treatment and survival data of patients with RHD. The registry may also lead to future therapeutic recommendations, provide a framework for future clinical trials and create excellent research opportunities.

The purpose of the study is to determine how blood sugar levels in individuals with and without hypoglycemia after bariatric surgery respond to different doses of glucagon, a hormone that is usually present in your body that regulates blood sugar levels. In this study, there will be 4 visits to the clinical research center. In the first visit, medical history and physical exam will be performed, and blood samples will be taken to assess overall health. During visit 2, a continuous glucose monitor will be placed under the skin. (This may be combined with visit 1, depending on the schedule of visits.) In visit 3, we will test the effect of a total of 4 different doses of glucagon, in increasing doses. In visit 4, we will test the effect of a total of 3 doses of glucagon, in decreasing doses. For both visit 3 and 4, we will infuse labeled stable glucose to allow us to measure how much glucose the body is making, and will measure levels of hormones which regulate glucose, such as insulin and glucagon.

The goal of this clinical trial is to develop an pharmacist-led preoperative opioid taper intervention for patients undergoing total knee or hip replacement who are on chronic opioids before their surgery. The main questions it aims to answer are: - Is the intervention feasible and acceptable to patients? - Does the intervention result in a decrease in opioid dose during the preoperative period? Participants will meet with a clinical pharmacist, who will provide some basic education on pain and opioids, and will propose an opioid taper schedule. The pharmacist will then follow-up with the participant by phone each week until surgery to assess progress and adjust the taper as necessary.

The proposed 6-month pilot Sequential Multiple Assignment Randomize Trial (SMART) has two aims. The first and primary aim is to determine the feasibility of conducting a full-scale SMART to compare weight-focused (i.e., weight loss) and weight-neutral (i.e., weight loss is not an explicit goal) adaptive biobehavioral interventions for improving cardiometabolic health in Black adults with overweight or obesity (BMI ≥27 kg/m2) plus at least one weight-related cardiometabolic condition (high blood pressure, prediabetes or diabetes, and/or high cholesterol). Biobehavioral interventions are treatment strategies that combine lifestyle-based behavioral interventions such as eating a healthy diet and exercise with medications. In this study, participants will be randomly assigned to receive either weight-focused or weight-neutral health coaching for 7 weeks. At week 8, participants will be identified as either "responders" or "nonresponders" to the initial interventions. The threshold for response in the weight-focused condition is greater than or equal to 3% weight loss. The threshold for response in the weight-neutral condition is engaging in greater than or equal to 150 minutes of moderate physical activity for the 7 days prior to the week 8 study visit. Responders to the initial interventions will continue with health coaching on a biweekly basis for weeks 9-26 of the intervention. Nonresponders will be re-randomized to either intensify the lifestyle-based intervention by receiving a membership to the YMCA and enrolling in group fitness classes or augmenting the health coaching with enhanced medical management in partnership with their established primary care provider. The second aim is to use clinical data from the pilot SMART to estimate treatment effects and the between-person variability in these effects. Because this is a pilot study, these estimates will not be used to make comparisons or draw conclusions on the comparative effectiveness of intervention conditions. Rather, these data will be used to generate preliminary effect sizes that can be used to estimate the sample size required for a full-scale trial. Clinical trial feasibility data will be collected on an ongoing basis throughout the study and clinical data will be collected prior to initiating the intervention (baseline) and at week 8 (response visit) and week 26 (post-intervention visit).

African Americans are less likely to receive quality end-of-life (EoL) care. Addressing disparities in EoL care will need efforts to support a better understanding of African American patients' EoL cultural values and preferences for EoL communication and the impact of historical and ongoing care delivery inequities in healthcare settings. Our proposed "Caring for Older African Americans" training program is designed to empower clinicians to improve goal-concordant EoL care delivery by using community-developed storytelling videos to create empathy with experiences of racism in EoL care, guidelines for culturally concordant EoL care delivery, and an implicit bias recognition and management training to mitigate bias in goals of care communication.
