NCT01788462
Sleep-disordered breathing is characterized primarily by partial or total upper airway obstruction during sleep. The most common form of sleep-disordered breathing is obstructive sleep apnea (OSA) due to recurrent collapse of the upper airway with the onset of sleep state. The major risk factors associated with the development of sleep apnea are obesity and male sex. The investigators have also found a high prevalence of OSA in HIV infected men and women, particularly among those with central lipohypertrophy, which is a common finding in HIV-infected persons receiving antiretroviral therapy. Currently, our overall hypothesis is that visceral adiposity, as seen in HIV-infected persons with central lipohypertrophy, alters both mechanical properties and compensatory neuromuscular responses leading to upper airway obstruction. Based on our most recent findings in the non-HIV population, the investigators demonstrate that obesity is associated with elevations in the upper airway load (passive Pcrit) that are counterbalanced by compensatory upper airway neural responses. Moreover, the investigators have found that female sex, peripheral adiposity, and younger age are associated with increased compensatory neuromuscular responses, while male sex, central adiposity, and older age are associated with blunted compensatory responses. The loss of the compensatory neuromuscular responses leads to obstructive sleep apnea. Among HIV-infected patients with central lipohypertrophy, tesamorelin (Egrifta), a growth hormone releasing hormone (GHRH) analogue, is approved for the reduction of visceral adipose tissue. The investigators hypothesize that tesamorelin therapy will reverse both the mechanical and neurocompensatory alterations associated with increased central obesity. In this project the investigators will determine whether tesamorelin affects sleep apnea severity and compensatory neuromuscular responses of the upper airway on sleep and breathing in men and women with HIV infection. The proposed studies are designed to elucidate the pathophysiologic basis for the development of obstructive sleep apnea in this population. The studies also provide insights into the neurohumoral regulation of upper airway function, and potentially new approaches to the treatment for sleep-disordered breathing.

NCT00103883
Identifying young people with early HIV-1 infection is important for increasing linkage to care, for behavioral counseling, and for enrolling individuals into programs that can provide effective interventions to disease progression and improve outcome. This study will develop and evaluate a saliva-based sensitive/less sensitive (S/LS) assay for differentiating persons with recent HIV-1 infection (less than 133 days) from those with established HIV-1 infection.
NCT01675323
Restless Legs Syndrome (RLS) research has focused on the sensory features and failed to address an important aspect of RLS; i.e. a 'hyperarousal' or profound chronic sleep loss without significant excessive daytime sleepiness. This hyperarousal produces RLS symptoms by overwhelming the normal inhibitory processes needed to decrease sensory and motor cortical activity for resting and sleep. Thus the hyperarousal produces both the RLS need to move when trying to rest and the inability to maintain sleep. The biological consequences of this hyperarousal process on sleep (increased wake time) and cortical excitability (as demonstrated by transcranial magnetic stimulation (TMS)) are postulated to reflect increased degree of excitatory glutamatergic activity, and therefore affected brain regions will show relatively increased glutamate (Glu) and glutamine (Gln) on MR spectroscopy (MRS). Changes in inhibitory activity and GABA may also occur, but less significantly than the increase in Glu/Gln. Our pilot MRS data discovered a new abnormality in RLS: increased Thalamic Glx (Glu + Gln) that correlated well with sleep measures of hyperarousal. Glx levels are not specific for the neurotransmitter role of Glu. In this project RLS and matching controls subjects will be studied using polysomnograms (PSG) and TMS and 7T MRI for MRS that provides accurate measurement of Gln levels, which reflect mostly neurotransmitter Glu activity. The first aim is to confirm that Gln is increased in the thalamus and to determine if this also occurs in the motor and sensory cortices. The relation between Glu, Gln and GABA will also be evaluated. Second, assessments will be made of the degree of relation between Gln increase and the hyperarousal effects on sleep and cortical excitability (TMS). This would demonstrate that abnormally increased Glu activity is primary to RLS hyperarousal and radically changes the emphasis in RLS to be less on dopamine and more on Glu-hyperarousal as a major feature of RLS.This is an entirely new direction for RLS research and treatment development. The new concept of hyperarousal adds a missing dimension to understanding RLS, namely the discovery of the Glu abnormality and its central relation to the other hyperarousal features.
NCT02036307
This is a trial of two marketed fish oil supplements, one with a high EPA:DHA ratio and the other with a high DHA:EPA ratio, to examine differential effects on platelet function, blood pressure, and fasting triglyceride levels.
NCT02366533
The goal of ATN 093 is to determine program-level factors associated with the effectiveness of SMILE in Caring for Youth Linkage-to-Care (LTC) program network at the 15 Adolescent Medicine Trial Units (AMTU). This will be accomplished by evaluating and categorizing the various LTC programs at the AMTUs and then examining the association between the LTC program characteristics (providers, practices, and systems) and the proportion of Human Immunodeficiency Virus (HIV)-infected youth, ages 12-24 years old, inclusive, linked to care and maintained in care. As such, this study focuses on LTC programs at the AMTUs as the unit of analysis and not the youth themselves.
NCT02089425
This is a randomized, double blind, placebo controlled, parallel group study to assess the efficacy and safety of K-103-IP compared with placebo patch for treatment of mild to moderate acute pain associated with ankle strain or sprain.
NCT02191358
This multicenter observational study aims to investigate the benefits of providing pharmacogenetic testing with the YouScript Personalized Prescribing System which includes a clinical decision support tool and individualized pharmacist recommendations to elderly polypharmacy patients who are most at risk of adverse drug events. The YouScript system is unique in identifying drug-gene, and drug-drug-gene interactions that are missed by existing systems, and represent over 35% of significant interaction warnings. Data analysis will assess the impact of recommendations for medication changes on clinical decision making, patient outcomes, and healthcare resource utilization to determine which medications, specialties, or patient segments derive the greatest benefit from this intervention. Data gathered from patients enrolled in this study will be compared to patients matched on key characteristics from Inovalon's MORE2 healthcare database.
NCT00612040

NCT00094536
The Her Option® Cryoablation Therapy System is a closed-loop cryosurgical device that is used to ablate the endometrial lining in pre-menopausal women with menorrhagia (excessive menstrual bleeding) due to benign causes. This is a non-incisional procedure, which can be performed in a physicians office with minimal sedation. Initial FDA clinical studies were conducted with a two-freeze treatment pattern consisting of a 4 minute freeze with the Cryoprobe positioned in one cornu followed by a second freeze of 6 minutes with the Cryoprobe repositioned in the contralateral cornu. Since completion of the early studies, many physicians have experimented with varying freeze patterns using longer freeze durations and/or additional freezes at the fundus and the lower uterine segment. The results, as reported in the literature, indicate that these extended freeze patterns produce significantly better results than the original regimen.
