NCT04959097
Retinoblastoma (RB) is a primary eye cancer that forms in the back of the eye of infants and toddlers. Traditionally, RB is diagnosed without a biopsy; tumor can only be studied once an eye has been surgically removed. Given this limitation, we use aqueous humor (AH), the clear fluid in the front of the eye to detect specific markers, or information, that comes from the tumor itself.
NCT06782308
The goal of this survey is to assess several aspects related to patient preferences regarding interventions for alleviating tinnitus through invasive electrical brain stimulation (neuromodulation). This survey covers the acceptance of a surgically-placed brain implant, of its associated risks related to the neurosurgical procedure, usability considerations, and the willingness/ability to pay for such a treatment. Neurosoft Bioelectronics will use the collected patients' feedback and usability preferences data for the development of a novel minimally invasive brain implant aimed at alleviating tinnitus.
NCT07461558
This study will compare two ways of managing a small, hidden hernia that can sometimes be found during minimally invasive surgery to repair a hernia on one side of the groin. Occasionally while fixing the known hernia, the surgeon discovers a small hernia on the other side that has not caused any symptoms. Surgeons do not agree on the best way to handle these hernias. Some believe it should be repaired right away during the same operation to prevent it from getting bigger or from causing symptoms later, which could require another surgery. Others believe it is better to leave it alone since it is not causing problems and groin hernia surgery carries risks including long-term pain. This study will randomly assign patients, if a hidden hernia is found during surgery, to either having it repaired immediately or to have it monitored over time. Patients will be followed up at 30 days, 1 year and 2 years following surgery. The researchers will compare recovery and quality of life between the two groups. For those in the monitoring group, the study will also track whether the hidden hernia causes symptoms or eventually needs surgery. The goal is to determine whether repairing the hidden hernia right away is as safe and effective as watching and waiting, so doctors and patients can make more informed decisions in the future.
NCT02725463
Although cochlear implants can restore hearing to individuals who have lost cochlear hair cell function, there is no adequately effective treatment for individuals suffering chronic imbalance, postural instability and unsteady vision due to loss of vestibular hair cell function. Preclinical studies have demonstrated that electrical stimulation of the vestibular nerve via a chronically implanted multichannel vestibular prosthesis can partially restore vestibular reflexes that maintain steady posture and vision. This pilot clinical feasibility study of a multichannel vestibular implant system will evaluate this approach in up to ten human subjects with bilateral vestibular deficiency due to gentamicin ototoxicity or other causes of inner ear dysfunction.
NCT05572073
This is a retrospective and prospective longitudinal study in participants with Otoferlin Gene-Mediated Hearing Loss.
NCT06424262
This clinical study will test a newly developed cochlear implant known as CI622D. This experimental cochlear implant has been designed to slowly release a drug called dexamethasone. Dexamethasone works to ease inflammation, which is common after any surgical procedure. The goal is to learn if there are added benefits in implant performance and hearing outcomes with the dexamethasone-releasing cochlear implant (CI622D) vs. the standard cochlear implant (CI622) without dexamethasone. The study will be conducted in adults with sensorineural hearing loss, a type of hearing loss caused by damage to the inner ear or auditory nerve. The study participants will undergo a series of tests that include testing their implant and their hearing. They will also complete questionnaires to see how they rate their hearing ability and their overall general health.
NCT07417956
In children aged 0 to 7 years, behavioral evaluation during cochlear implant programming is often difficult or unreliable. Objective, reproducible, and rapid markers are therefore essential. While objective measures such as ECAP (electrically evoked compound action potentials) help guide safe programming, they can show inter-electrode and inter-subject variability. Electrically evoked stapedius reflex threshold (eSRT) has emerged as a relevant objective marker to approximate the comfort level of stimulation. Pediatric studies indicate that eSRT can be measured in the majority of children, closely corresponds to the comfort level, and is associated with improved speech outcomes when programming is guided by eSRT. In our previous single-center study in children aged 8 to 17 years (N=30; 44 implanted ears), eSRT was obtained in 83.3% of patients, with strong correlation between C-subjective and C-eSRT thresholds (r\>0.94; p\<0.001) across all electrodes. Tonal performance remained stable, and speech intelligibility, particularly in noise (FraSiMat), significantly improved with an eSRT-based program after one month of habituation. Daily device use remained stable, reflecting good clinical acceptability. These results support the relevance of systematic integration of eSRT in routine programming. The aim of the eSRT2 study is to evaluate the feasibility and reliability of eSRT measurement in real-world clinical care for children aged 0 to 7 years, and to monitor its stability during post-operative follow-up. Improved auditory accessibility and better-controlled acoustic comfort through eSRT are expected to accelerate speech development in children by enabling earlier improvements in vocal performance and intelligibility.
NCT04857255
This study is testing the effectiveness of augmentative and alternative communication technology among deaf or hard of hearing children for improving language development. Children will be randomized to receive either the technology intervention or treatment as usual
NCT06058767
Children who are deaf or hard-of-hearing (D/HH) are at risk of speech and language delays, which can be mitigated through early identification and intervention. Identifying hearing loss (HL) during preschool is crucial, but the most effective hearing screening method for preschoolers remains uncertain. The purpose of this study is to learn whether, compared to the gold-standard two-stage Pure-tone audiometry (PTA) + otoacoustic emissions (OAE) screening (TS-PO), single-stage OAE (SS-O) screening alone is not inferior at identifying hearing loss when performed in a community-based preschool setting. This study holds the potential to improve early hearing loss detection and intervention among D/HH children, reducing the likelihood of speech and language delays. A diverse group of 13,764 preschool-age children across community-based preschool centers will be recruited. The intervention involves all subjects undergoing both PTA and OAE screening, with the order determined through randomization. Children who show potential hearing issues based on screening results or teacher concerns will receive further testing to determine the final hearing outcome. Group allocation will be post-hoc, based on their screening results. In addition to the primary objective, the study will compare other hearing screening measures and outcomes between the two methods (TS-PO and SS-O). This approach aims to reflect the real-life effectiveness of hearing screening in a diverse population. Ultimately, the study seeks to provide insights into an optimal hearing screening method that could prevent speech and language delays among D/HH children.
NCT06781749
The goal of this clinical trial is to learn if hearing devices, like hearing aids, affect social and cognitive function of older adults. The main questions the researchers want to answer are: * How social are older adults with hearing loss before and after using hearing devices? * How well do older adults with hearing loss think before and after using hearing devices? * For older adults who have hearing loss and use hearing devices, do changes in social interaction explain changes in how well they think (cognitive function)? * Do brainwaves (EEGs) in older adults with hearing loss change after using hearing devices? * Are there differences in how social older adults with hearing loss are compared to older adults without hearing loss? What Participants Will Do: * Participants will take questionnaires for around 60 minutes. Questionnaires will ask participants about their background, health, hearing, and how social they are. Another set of questionnaires will check their thinking ability or cognition. * Participants will wear an audio sensor (TILES Audio Recorder on Jelly Mobile phone) for 2 weeks. The sensor will collect and store information about a participant's voice during conversations. Once the device has information about a participant's voice such as pitch and tone it will store this information and delete the audio recording. Words spoken during conversations will be deleted. * (Optional) Participants can choose to participate in a 45-60-minute EEG (electroencephalogram) recording session. Participants will have sensors placed on top of their heads. Sensors will record the participants' brainwaves. Sounds will be played to see how participants' brainwaves change when they hear sounds. Eligible participants will be invited to participate in 4-month follow-up study.
NCT05674786
Although cochlear implants can restore hearing to individuals who have lost cochlear hair cell function, there is no widely available, adequately effective treatment for individuals suffering chronic imbalance, postural instability and unsteady vision due to bilateral vestibular hypofunction. Prior research focused on ototoxic cases has demonstrated that electrical stimulation of the vestibular nerve via a chronically implanted multichannel vestibular implant can partially restore vestibular reflexes that normally maintain steady posture and vision; improve performance on objective measures of postural stability and gait; and improve patient-reported disability and health-related quality of life. This single-arm open-label study extends that research to evaluate outcomes for up to 8 individuals with non-ototoxic bilateral vestibular hypofunction, yielding a total of fifteen adults (age 22-90 years at time of enrollment) divided as equally as possible between ototoxic and non-ototoxic cases.
NCT04006431
Prostate embolization is an alternative treatment to trans urethral prostate resection in the context of benign prostatic hypertrophy. This embolization treatment is also of interest in patients with chronic anuria surveyed in relation to their prostatic hypertrophy for disundation. This survey causes discomfort and urinary tract infection. It is a population with tortuous arteries, a severe atherosclerotic overload making embolizations complex and long. Often, only unilateral embolization is possible. The purpose of this study is to compare the effectiveness in terms of disundation of unilateral vs. bilateral embolization of the prostatic arteries
NCT06641999
This study will test an experimental Tinnitus Implant System that consists of a cochlear implant, sound processor and programming software. The Tinnitus implant is surgically placed under the skin just behind the ear in the mastoid bone. It has an electrode that extends from the implant into the promontory bone of the cochlea which emits electrical signals that stimulate the auditory nerve. The sound processor is worn behind the ear and powers the implant via the coil. The study will be conducted in adults with moderate to severe chronic tinnitus who have normal hearing to moderately severe hearing loss in the inner ear. The study participants will undergo a series of tests that include evaluations of tinnitus loudness and annoyance, and self-reported questionnaires on their tinnitus and general health.
NCT05802212
The purpose of the study is to understand the effect of Metformin on patients with PCOS.
NCT06642935
This clinical study will test a new investigational totally implanted cochlear implant system (TICI G2). The cochlear implant has an implantable microphone under the skin to detect speech and sound from the environment allowing hearing without the need of any external parts. This study will explore new ways to process the sound from the implanted microphone. The study will be conducted in adults with sensorineural hearing loss, a type of hearing loss caused by damage to the inner ear or auditory nerve. The study participants will undergo a series of tests that include testing their implant and their hearing. They will also complete questionnaires to see how they rate their hearing and overall general health.
NCT04591093
Main objective: Investigate on new cochlear implanted patients whether the FineHearing strategy of the MED-EL cochlear implant gives better results on musical perception if the depth of stimulation (stimulation or not of the apical areas) is greater. Secondary objectives: Evaluate the effect of stimulation depth on vocal audiometric results, results of differential frequency threshold test and on qualitative sound perception.

This is a Biomedical Research, prospective, randomized, controlled single-blind mono centric, phase IV comparison trial of the bilateral TAP block versus curare in muscle relaxation of the abdominal wall during laparoscopic digestive surgery.
NCT07228845
Access to affordable and timely hearing healthcare remains a major challenge for many individuals, partly due to the high cost and long turnaround time. This study will explore whether 3D-printed ear tips perform as well as or better than standard ear tips in terms of sound quality, comfort, and fit over a prolonged duration in a sample of individuals with bilateral hearing loss. It will also compare how long each method takes to make and how much each costs.
NCT06860022
The proposed research addresses a long-standing and important challenge of improving literacy skills of children who are deaf and hard of hearing, a historically under researched group. The investigators aim to leverage shape coding - an empirically validated intervention approach for constructing sentences in spoken English - for improving how efficiently children who are deaf and hard of hearing learn to correctly construct sentences in written English. To advance the promising yet underutilized research on shape coding, the investigators complete the next logical step of applying the visual supports provided with shape coding to written language for deaf and hard of hearing children. Shape coding has been effective for teaching sentence structure in spoken English to children with language disabilities and has recently been applied to sentence structure in American Sign Language with deaf and hard of hearing children. Intervention involving shape coding is predicted to result in increased accuracy of word order in sentences in written English because deaf and hard of hearing children often benefit from visual information. The investigators will accomplish this aim using single case multiple probe across participants design studies with 30 fifth through eighth grade children who are deaf and hard of hearing. The knowledge gained will guide language and literacy intervention for children who are deaf and hard of hearing.
NCT06021132
The study will follow a cohort of CI-candidates becoming CI-user, till two years postoperative. A through-out assessment of both their audiological and vestibular status will be carried out at multiple fixed timepoints over 2 years, evaluating both subjective (patients reported) and objective outcomes over time. For the audiological part of the study both pure-tone and speech audiometry results will be held against the patient perceived benefit of the treatment as assessed by the questionnaires NCIQ and SSQ-12. The vestibular part of the study will evaluate the function of the SCCs and the sacculus. This is will be put in concert with functional tests of the vestibular system, and the patient perceived outcome measure DHI. Correlations between vestibular and audiological performances will be examined. A collection of specific hypotheses will be tested by predefined statistical methods.
