There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
A. Introduction to the Problem This field experiment is intended to explore whether supplemental transcranial magnetic stimulation (TMS) is more effective than standard medication mono-therapy for the treatment of major depressive disorder. Transcranial magnetic stimulation (TMS) is now included in the practice guidelines of the American Psychiatric Association for the treatment of major depression. B. Importance of the Area of Study The safety, efficacy and value of TMS treatment has been established through the four-phase FDA approval process. The evidence of TMS safety and efficacy derives from multiple, peer reviewed, double-blind, randomized, control trials (RCT) with sham control as well as strict enrollment and methodological requirements. TMS is now used in actual clinical practice and there is an opportunity to extend laboratory research and typical, highly controlled field settings to applied settings. This study is designed to gather data on safety, efficacy and utility of TMS as it is used in clinical practice. C. Need for Additional Research Efficacy and safety of these interventions have been scientifically established and meta-analyses of these studies underscore the efficacy and safety of two treatment interventions to be employed in this study: 1) standard medication monotherapy and 2) standard medication therapy supplemented with TMS. However, many authors conclude that depression can be difficult to treat and there is an ongoing need for additional research. Depression remains a major public health problem.
Our routine practice for patients undergoing mastectomy is to include paravertebral peripheral nerve blockade for postoperative analgesia. This study investigates whether the addition of another nerve block targeting the pectoral nerves will improve that analgesia.
The skin and intestinal tracts of humans are covered with microbes, and the gene products of these microbes are collectively known as the human microbiome. Many studies in recent years have linked the microbiome to many aspects of human health and disease. Premature infants are vulnerable to invasive infections, some of which may originate from the microbes that colonize the skin and in the intestinal tract. Therefore, determining the patterns of early life colonization and the sources of colonization in these infants may be critical to determining infectious risks. This prospective study is proposed to identify the sources of microbes that colonize extremely low birth weight (ELBW; <1000 g birth weight) infants immediately following birth through the first month of life. The study team plans to non-invasively survey the skin and stool of ELBW preterm infants in combination with sampling of their mothers' skin and stool and the intensive care nursery (ICN) environment. As controls, the study team will perform a similar survey of full term mother-infant pairs. Samples will be analyzed using high throughput sequencing techniques to determine microbial content. Topical barrier sprays or emollients are commonly used early in life in the ELBW infant to reduce insensible water loss and enhance the integrity of the skin barrier. The effect of these treatments on the development of the skin microbiome remains unknown. As part of this study, the study team also proposes the application of two different skin barrier therapies to small areas on infant's legs to determine the effects of the different treatments on skin colonization. While all parts of the study are described in this summary and the detailed description, the remainder of the record focuses on this interventional portion of the study (Group 2). The goals of this study are outlined as follows: 1. To elucidate the relationship between microbes in the health care environment and colonization patterns of the intestinal tracts in preterm and term infants. 2. To understand the relationship between mode of delivery, the health care environment, and the colonization of the skin in preterm and term infants. 3. To determine the effects of topical skin barrier therapies on the colonization patterns of the skin in preterm infants. 4. To ascertain the relationship between the composition of the microbes colonizing preterm and term infants and the development of mucosal and systemic immunity to those microbes.
The purpose of this study is to compare the effectiveness of two different augmentation strategies of antidepressant treatment for depressed older adults who have not responded to an adequate trial of antidepressant medication. The first augmentation strategy is Problem Solving Therapy (PST), a 12-week psychotherapy treatment that has been shown to be effective in depressed older adults. The second augmentation strategy is medication augmentation, which will begin with six weeks of aripiprazole, an atypical antipsychotic medication that has also been shown to be effective in depressed older adults who have failed a trial of antidepressant medication.
This pilot clinical trial studies short-infusion ziv-aflibercept in treating patients with metastatic colorectal cancer receiving combination chemotherapy. Ziv-aflibercept may stop the growth of colorectal cancer by blocking blood flow to the tumor. Giving the drug over a shorter infusion time may result in improved efficiency and patient satisfaction.
This study will attempt to determine whether having gastric bypass surgery changes the way that the gut absorbs hormones from birth control pills. It is believed that, because gastric bypass surgery causes malabsorption of nutrients and some medications, the levels of birth control hormones after the surgery will be lower than in women before they have the surgery. The investigators will ask several women to take a pack of birth control pills before having bypass surgery, and then another pack several months after surgery. The investigators will measure hormone levels in the blood. The investigators will also measure outcomes that may tell us how well the birth control pills are working, such as ultrasounds of the uterus and ovaries, and examination of the cervix.
It is believed that when androgen (testosterone) levels are below normal there is a disturbance of normal bodily functioning that is associated with priapism in some men. Conversely, it is believed that testosterone replacement will improve the condition of priapism when the testosterone levels are brought to normal. In turn, this will also improve psychological well being in men with sickle cell disease (SCD).
The goal of this study is to determine if the use of tranexamic acid, a safe and effective antifibrinolytic, in patients with intertrochanteric hip fractures will result in a reduction in blood transfusion rates. Treatment will be administered pre-operatively as well as at the time of surgical incision. The primary outcome will be need for blood transfusion. Secondary outcomes will include calculated perioperative blood loss, length of stay, cost of inpatient care, and rate of adverse events, including DVT, PE, infection, MI, cerebrovascular event, need for re-hospitalization or re-operation and 30 day mortality.
The purpose of this study is to demonstrate the safety and effectiveness of the study drug Nebivolol, in people who suffer with high blood pressure with Chronic Obstructive Pulmonary Disease (COPD).
The purpose of this study is that an adductor canal nerve block (putting numbing medicine near the nerve) has been shown to produce excellent pain relief with less pain medication use after knee replacement surgery.The investigators will be comparing the amount of pain relief following knee replacement surgery when you have a nerve block in place. There will be approximately 66 subjects participating in this study. After surgery subjects will receive numbing medication every 6 hours for 48 hours. Subjects will also receive a morphine PCA (patient controlled analgesia) after surgery and pain medication by mouth every 4 hours around the clock with the option to receive more pain medication if needed. Subjects will participate in the study up to 3 days.
