438 Clinical Trials for Various Conditions
This study aims to collect tear samples from 50 women who have been recently diagnosed with breast cancer.
Purpose: * To determine the presence of SARS-CoV-2 in tears * To determine SARS-CoV-2 receptors in tear production system
To evaluate the safety and feasibility of adipose-derived regenerative cells injected into tears of the hamstring muscle.
The purpose of the research is to determine which inflammatory substances are involved in causing allergic symptoms in the eye. Allergic conjunctivitis is a common problem with symptoms of temporary redness, itching, tearing, and swelling of the eyes. Substances released by cells in the affected tissues cause allergic reactions in the eye and elsewhere in the body.
The purpose of this research study is to evaluate tendon healing when using the Flexible Suturing System with Anchors (FSSA) to surgically repair full-thickness rotator cuff tendon tears.
A randomized, single-site, parallel-group, prospective study of patients who are candidates for SLT, to study the effect of IOP change with Rocklatan vs artificial tears.
The purpose of this study is to evaluate reflex tear production following cotton swab nasal stimulation in subjects with dry eye disease (DED).
The purpose of this study is to evaluate tear production following acute administration of AR-15512 ophthalmic solution 0.003% (0.003% AR-15512) in subjects with dry eye disease (DED).
The purpose of this study is to evaluate the safety and effectiveness of dual platelet rich plasma (PRP) injections into the rotator cuff insertion and the area of the tendon proximal to the insertion.
Regenerative medicine, specifically orthobiologics is a hot topic in the community and in Sports Medicine. Riding the hype curve of a new treatment can be great when offering new procedures to patients. However, as the excitement regarding potential benefits of orthobiologics grows, it is valuable to grow the body of literature on their safety and efficacy in various musculoskeletal conditions. Furthering the body of data regarding which musculoskeletal conditions may benefit most from these treatments and which may not can help guide physicians on when to incorporate orthobiologics into clinical practice. More robust data can help physicians guide patients and patient expectations when discussing treatment options. Platelet rich plasma (PRP) in musculoskeletal medicine is most commonly used to treat tendinopathies and degenerative joint disease. The American Medical Society for Sports Medicine released a position statement in November of 2021 summarizing meta-analysis and systemic review data evaluating efficacy and major adverse events of PRP for tendinopathy and osteoarthritis1. At this time, the most robust data exists for lateral epicondylopathy as multiple randomized controlled trials demonstrate positive response to PRP. Gluteus medius tendinopathy and plantar fasciaopathy similarly have positive data. In Achilles tendinopathy, well designed RCTs have shown no difference between PRP and saline injections. These data should help guide physicians in responsible use and patient counseling. Data from Hurley et al. suggest PRP may augment rotator cuff repair with improved rates of healing and reduced overall pain. However, there are limited high quality studies on the efficacy of PRP alone in partial rotator cuff tear. Partial rotator cuff tear is a common musculoskeletal complaint that can be treated with conservative measures such as physical therapy and corticosteroid injection. It can also be treated with surgical intervention if those modalities provide incomplete or inadequate pain relief and functional restoration. This study aims to evaluate if PRP is an efficacious treatment modality for partial rotator cuff tear.
The goal of this observational study is to evaluate the effectiveness and safety of the Integrity bio-inductive implant in treating partial and full thickness rotator cuff tears. The main questions it aims to answer are: * How does the application of the Integrity implant affect patient-reported outcome measures (PROMs) such as ASES, SANE, and PROMIS? * What are the imaging characteristics of the rotator cuff tears at 3 and 6 months postoperatively when using the Integrity implant? Postoperative MRIs will be obtained from 10 consecutive patients who have undergone rotator cuff repair using the Integrity implant at 3 and 6 months after surgery. Participants include those with partial and full thickness tears treated with different surgical techniques involving the implant. They may receive either isolated onlay use of the graft for partial tears or augmentation of a standard single or double row repair with the graft applied to the superior surface of the repair.
Platelets are small cells found in the blood that help form clots and stop bleeding. Platelet-rich plasma is blood that contains more platelets than normal and can be given to help people with pain. Tears of the Labrum to the hip (the cartilage "suction cup" that holds the ball to the socket of the hip) cause hip pain. The study wants to see if a portion of the patient's blood, the platelets, will help relieve hip pain and function. Participation requires completing surveys by email, text message, in person, and/or by telephone. Medical tests will also be done to track the health of participants.
The purpose of this prospective interventional study is to compare post-intravitreal injection pain between eyes receiving topical bromfenac versus artificial tears as an analgesic after intravitreal injection.
The association of radioiodine therapy for the treatment of thyroid cancer with nasolacrimal duct obstruction has been well documented in the medical literature. Prior case reports have documented radioactive iodine detection in the tears of patients following radioiodine therapy. It is possible that radioactive uptake by the cells in the lacrimal sac and nasolacrimal duct lead to inflammation, fibrosis, and obstruction of the tear duct over time. A recent study has shown that the administration of artificial tears decreases the level of detectable radioiodine in the tears of patients undergoing radioiodine therapy for thyroid cancer. The purpose of this study will be to assess whether administering tears after radioactive iodine therapy for thyroid cancer decreases the incidence of nasolacrimal duct obstruction in the two years following radioactive iodine treatment.
This study aims to evaluate the safety and effectiveness of arthroscopic rotator cuff repair augmented with the BioBrace® Implant vs. arthroscopic rotator cuff repair alone in subjects requiring surgical intervention for a full-thickness rotator cuff tear.
The purpose of this study is to determine differences in pain, functional patient reported outcomes, and objective imaging parameters following non-operative and meniscus root repair treatment. Furthermore, the long-term goal of this research proposal is to understand the natural history of meniscal root tears and their subsequent repair, in order to better determine risk factors for inferior outcomes and progression to osteoarthritis (OA).
The purpose of this study is to compare postoperative healing of large and massive rotator cuff tears with preoperative MRI confirmed fatty infiltration stage II and higher repaired with or without dermal allograft augmentation (DAA).
Background and Objective: To evaluate the efficacy of cooled versus room temperature artificial tears in reducing post intravitreal injection (IVI) ocular discomfort. Patients and Methods: Patients receiving IVI were randomized to either cooled or room temperature tears intervention groups. Both groups rated their ocular discomfort following IVI before intervention and again after administration of cooled or room temperature tears.
Determine the effect of a single instillation of NOV03 on the thickness and evaporation rate of the mucus-aqueous layer of the tear film
Dry eye disease (DED) is pervasive with some reports estimating over 16 million adults diagnosed in the United States. Currently, artificial tears remain an integral part of managing dry eyes and are mainly used for symptomatic relief. Recent studies have shown there may be therapeutic benefits with regular use of lipid-based artificial tears to improve the structure of the tear film, which may improve tear film stability and provide relief of symptoms. In this study the investigators propose to compare effects on the tear lipid film and its dynamics between 3 lipid based artificial tears and a widely available non-lipid based artificial tear.
The long head of the biceps (LHB) tendon is thought to be a common source of shoulder pain and dysfunction in patients with rotator cuff pathology. Tenotomy and tenodesis have been shown to produce favourable and comparable results in treating LHB lesions, but a controversy still exists regarding the treatment of choice. Some suggest that tenotomy should be reserved for older, low-demand patients, while tenodesis should be performed in younger patients and those who engage in heavy labor. Proponents of tenotomy suggest that this is a technically easy procedure that leads to easy rehabilitation and fast return to activity with a low complication and reoperation rate. However, those who support LHB tenodesis list good preservation of elbow flexion and supination strength, improvement of functional scores, elimination of pain, and avoidance of cosmetic deformity as benefits of the procedure. Alternatively, the LHB can be maintained in the joint without tenodesis or tenotomy. In fact, it has not been clearly shown that LHB tenodesis or tenotomy leads to improved outcomes compared to leaving the biceps tendon intact.
The focus of this study is to examine changes in pain scores, strength, and range of motion over time following an ultrasonic tenotomy on a partial tear (\<50%) of the supraspinatus tendon of the rotator cuff.
A randomized, controlled, double-masked, investigator-initiated trial to evaluate tear film quality and stability in subjects with dry eye disease using OC-01 (varenicline solution) nasal spray 0.03 mg as compared to vehicle control nasal spray.
This will be a vehicle-controlled, masked, randomized study conducted at a single site in the United States. All participants enrolled will have Dry Eye Disease (DED). The study will consist of 2 Visits. At Visit 1, eligibility will be assessed at Screening. All eligible subjects will then be enrolled and randomized to one of two treatment groups (1:1): active (0.003% AR-15512) or control (AR-15512 vehicle). Subjects in each treatment group will then be randomized 1:1 to which Visit (Visit 1 or 2) anesthetic will be used with the Schirmer test.
The purpose of the study is to assess whether the REGENETEN™ Bioinductive Implant allows patients to get back to their everyday activities quicker than if the tendon is repaired by the standard repair technique 'Completion and Repair' for surgically treating partial-thickness rotator cuff tears.
The purpose of this randomized-controlled study is to compare outcomes of arthroscopic rotator cuff repair augmented with a Bioinductive Implant (study group) to standard arthroscopic rotator cuff repair (control group). The primary outcome of this study is rotator cuff repair integrity (absence of full- or partial-thickness defect) demonstrated on ultrasound at 1-year postoperatively. The investigators hypothesize that the study group will have higher rates of repair integrity demonstrated on ultrasound at 1-year postoperatively.
In patients with NGLY1-CDDG, the disorder can lead to eye damage due to not being able to produce enough tears. This study is being done to see if the dietary supplement, GlcNAc, improves tear production in patients with NGLY1-CDDG.
This is a longitudinal follow-up study of the RC-002 study, in which up to 246 subjects assigned to two randomization arms will be enrolled: an adipose-derived regenerative cell (ADRC) injection arm (ADRC treatment arm) and the SOC corticosteroid injection arm (active control arm). All subjects will be randomly assigned to ADRC treatment or active control arms in a 2:1 ratio and will be followed up for 6 months. The goal of the RC-004 study is to enroll all patients that were enrolled and treated in RC-002 and follow for 3 years.
Carboxymethylcellulose (CMC), a common component in artificial tears, has been shown to modify the gut microbiome. The study is examining its effects on the eye microbiome, which may have implications on ocular disease and artificial tear choice. The study will administer artificial tears containing CMC to the treatment group and artificial tears without CMC to the control group. Surveys and conjunctival swabs will be collected before and after treatment for bacterial genome sequencing and analyzed by R statistical packages.
The purpose of this study is to explore the tear lipid layer quantitatively and qualitatively before and after use of a perflurohexyloctane eye drop (NovaTears)
