The goal of this clinical trial is to compare the delay in ovulation between placebo to levonorgestrel plus meloxicam in obese women with normal menses. The main questions it aims to answer are: 1. Ovulation will be delayed by ≥7 days following the first dose of levonorgestrel plus meloxicam compared to ovulation within 3 days following the first dose of placebo. 2. There will be no difference in unscheduled vaginal bleeding or adverse events between the two treatments \[placebo versus levonorgestrel plus meloxicam\]. Participants will: * undergo two treatment cycles the 1st uses placebo and the 2nd is levonorgestrel plus meloxicam, * maintain daily diary logs for adverse events, unscheduled bleeding, and onset, cessation, and amount of menstrual bleeding, * collect daily first morning voided urine from menstrual day 9 to 24, * undergo transvaginal ultrasound for ovarian follicle development on menstrual days 9, 11,13 and 14. * allow a blood sample to be drawn on days with ultrasound scans. * Take 1st placebo and levonorgestrel plus meloxicam under observation when dominant ovarian follicle is 17 ±1.0 millimeters (mm) in diameter and 2nd dose 48 hours later. Researchers will compare the placebo cycle to levonorgestrel plus meloxicam to see if ovulation is delayed, there is unscheduled vaginal bleeding, menstrual onset is delayed or there is an abnormal amount or duration of menses, there is any difference in treatment emergent side effects and any change in vital signs Read Less

This clinical trial determines if an oral medication taken within 2 days of anticipated ovulation will delay ovulation by 7 days. The study compares oral placebo tablets (control) to oral levonorgestrel, a synthetic hormone, and meloxicam, a non-steroidal anti-inflammatory drug (treatment) in 21 healthy women between the ages of 18 to 40. The control or treatment are taken 48 hours apart in the first and second menstrual cycle, respectively. The first dose is taken when the ovarian follicle has a diameter of 17 mm measured by transvaginal ultrasound. This follicle diameter is found 2 ± 1.0 days before ovulation. Ovulation is determined by a change in urinary hormone levels analyzed in first morning daily urine. The Investigators anticipate that the control cycle will have an interval to ovulation of ≤ 3 days from first placebo to ovulation while a delay of ≥7 days is found between first treatment to ovulation. A second question is to determine the side effects between control versus treatment based on symptoms such as nausea or abdominal cramping, change in blood pressure or pulse rate and the interval in menstrual bleeding. Each study participant has approximately 9 visits during each of two menstrual cycles. The visits between menstrual day 9 (first visit) to largest follicle are 3 to 6 depending upon follicle growth. A blood sample with a transvaginal ultrasound for ovarian follicle diameter is obtained at each visit. The appropriate medication is taken when the ovarian follicle largest diameter is 17 mm. The second dose is taken 2 days later with interim and final visits at 5 and 10 days following first dose. Each participant collects first morning urine from menstrual day 9 to 23. A teaspoonful of morning urine is placed in a storage tube and kept in a refrigerator freezer section until returned at a scheduled visit. All urine samples are kept frozen until analyzed for the metabolites of estrogen and progesterone by a central research laboratory. A change in the ratio of estrogen to progesterone metabolites is indicative of ovulation because more progesterone is secreted after ovulation from the ovary. The primary research outcome compares the interval in days from first dose of medication to ovulation between control and treatment. Secondary outcomes are menstrual cramps, vaginal bleeding, nausea, and headache, and changes in blood pressure, pulse, and interval between menstrual periods in control compared to treatment cycles.

Lower limb amputees rely on their prosthetic to remain active and lead an independent life. In recent years, measuring residual muscle activity has been used to interpret a user's intent and thereby modulate prosthesis control. However, little knowledge is held on how residual muscle activity differs from non-amputated muscle. The research team will analyze and compare neuromuscular physiology in non-amputee individuals and amputees' non-amputated and residual muscles across functional tasks to better understand how amputees control their muscles. Such information will inform design of modern prosthesis controllers. Read Less

Robotic lower limb exoskeletons aim to improve or augment limb functions. Automatic modulation of robotic assistance is very important because it can increase the assistive outcomes and guarantee safety when using exoskeletons. However, this automatic assistance adjustment is challenging due to person-to-person and day-to-day variations, as well as the time-varying complex human-machine-interaction forces. In recent years, human-in-the-loop optimization methods have been investigated to reduce participants' metabolic costs by providing personalized assistance from robotic exoskeletons. However, metabolic cost measure is noisy and the experimental protocol is usually relatively long. In addition, the influence of exoskeleton control on this human state in terms of energetic cost is unclear and indirect. More importantly, the optimization by reducing metabolic cost is found to affect human gait patterns and cause undesired outcomes. In this study, new evaluation measures other than metabolic cost will be investigated to optimize the assistance from a powered hip exoskeleton based on a reinforcement learning method. It is hypothesized that the new reinforcement learning-based optimal control approach will produce personalized torque assistance, reduce human volitional effort, and improve balance and other performance during walking tasks. Both participants without and with neurological disorders will be included in this study. Read Less

This is an adaptive platform. This study is being done to collect information that will help us identify trends in patients with sepsis and other health conditions being readmitted into hospitals within 30 days of being discharged. This information will be used to create a computer tool that will help predict a patient's risk of being readmitted into the hospital after being discharged. Participants will allow the study team to follow their health after they are discharged by taking their temperature once a day and placing their index finger over their smartphone camera when prompted by a text message. Participants will receive the text messages twice a day. When the participant receives the text message, they will click on the link and follow the instructions. Instructions include how to long to keep your finger on your phone camera and how to report your daily temperature. Additional questions will also be asked. After 30 days, the text messages will stop, and participation will be complete. Read Less

This is a study of a medical procedure that utilizes a commercially available catheter (the Bullfrog® Micro-Infusion Device) to locally deliver a commercially available anti-inflammatory drug (dexamethasone sodium phosphate injection) around the deep veins after DVT recanalization, where DVT symptoms were present for at least 14 days and no more than 60 days prior to recanalization. The goal of the study is to see if local anti-inflammation helps prevent re-thrombosis of the blood vessel and improvement in symptoms for up to 24 months after the initial DVT recanalization procedure.

Secondary objectives include further evaluating the impact of LF111 and DRSP 3.5 mg chewable tablets on BMD and bone turnover after 12 months (13 medication cycles) in comparison to non-hormonal contraceptive methods and assessing the general safety and tolerability of LF111 and DRSP 3.5 mg chewable tablets in comparison to non-hormonal contraceptive methods. Exploratory objectives include evaluating the impact of LF111 and DRSP 3.5 mg chewable tablets on body fat and lean mass after 12 months (13 medication cycles) of investigation. Read Less

The U.S. Committee for Refugees and Immigrants (USCRI) has developed the Relationships, Education, Advancement, and Development for Youth for Life (READY4Life) Program. This is a 16-hour program for immigrants/refugees, ages 14 to 24. The program is designed to help young immigrants and refugees prepare for a successful life in the United States. The program is taught by USCRI program staff and is being implemented at eight sites across the U.S.: Cleveland, Ohio; Colchester, Vermont; Des Moines, Iowa; Miami, Florida; Philadelphia, Pennsylvania; Raleigh, North Carolina; Saint Paul, Minnesota; and Twin Falls, Idaho. The project also includes a rigorous evaluation component, featuring a Randomized Control Trial (RCT) design. Read Less
