Filter by:To compare the efficacy to different profiles, direct head-to-head studies had been conducted. In one previous review study revealed that TG LASIK provided patient with better uncorrected visual acuity (UCVA) than WFO LASIK and WFG LASIK. In recent previous contralateral eye studies also showed that TG LASIK induced less postoperative higher-order aberration than WFO LASIK. However, these studies included only low-to-moderate myopia patients, for patients with high myopia (spherical equivalent > 6D), the effect of TG LASIK comparing with WFO LASIK had not been reported before. The aim of our study is to analyze and compare the visual performance of TG LASIK and WFO LASIK in high myopia and low-to-moderate myopia patients, , particularly UCVA, corrected distance visual acuity (CDVA), contrast sensitivity (CS), and wavefront aberration.
In a randomized controlled trial, the investigators intend to measure the health impact of time-restricted eating (TRE) in obese patients (body mass index (BMI) ≥ 30 kg/m2), who habitually eat for more than 14 hours every day. Patients will be randomly assigned to a control group of behavioral nutritional counseling (standard of care) or the intervention group of behavioral nutrition counseling with the addition of adopting a 10-hour eating window for 12 weeks (TRE).
This is a multi-center, randomized, double-blind, placebo-controlled food challenge to be conducted in infants or children with confirmed IgE-mediated cow's milk allergy (CMA), followed by a 7-day open feeding of the experimental formula.
To evaluate the safety and effectiveness of Sodium Stibogluconate in the treatment of myelodysplastic syndrome/acute myeloid leukemia (MDS/AML) with p53 mutation from a defined list. The list includes 65 p53 mutations that were experimentally confirmed to be pharmacologically restored with tumor-suppressive function by antimonials.
Background: Early childhood development is highly dependent on the sensitive care provided by their caregivers . Interventions focused on supporting parents to improve their sensitivity have been shown to be effective . The COVID-19 pandemic has had a great impact on mental health , with pregnant women and mothers of children under one year of age being an especially vulnerable group . On the other hand, access to mental health interventions in person is restricted by confinement measures , especially group interventions, so it is relevant to have remote interventions that support this group of mothers. Objectives: to evaluate the feasibility and acceptability of a group videoconferencing intervention to improve maternal sensitivity aimed at mother / infant dyads attended in Primary Health Care in Chile Methodology: a randomized pilot feasibility study will be carried out with a mixed design with quantitative and qualitative evaluations. A face-to-face group intervention with proven effectiveness will be adapted to videoconferencing format , then 50 dyads will be randomized in a 3: 2 ratio to receive the videoconferencing intervention ( n=30) or the delivery of educational brochures (n=20) . The feasibility and acceptability will be evaluated assessing the participation, adherence and satisfaction in a quantitative way, in addition the qualitative evaluation will be carried out through interviews and focus groups. Changes in clinical outcomes will also be evaluated: maternal sensitivity, depressive symptoms, postnatal maternal attachment and infant socio-emotional development. This pilot study will allow the identification of the key parameters for the implementation and evaluation of the intervention, which will allow the design of an effectiveness study in the future.
The aim of the study is to assess the efficacy of the product M89 probiotic fractions in improving the symptoms of rosacea patients with sensitive skin after 30 days of treatment, in comparison with an area treated with the habitual skin care product. 20 women with sensitive skin (positive reaction to stinging test), suffering from persistent centrofacial erythema of rosacea with no more than 3 papules and pustules apply the product on half a face, twice a day, for 30 days. The subjects use their habitual skin care product on the other side of the face. The product efficacy is supported by significant improvements in the mean basal values of the following instrumental parameters: skin hydration (increase), trans-epidermal water loss (decrease), skin erythema (a* parameter decrease). The efficacy and the tolerability of the product is also showed by a visual clinical assessment of the face skin conditions and by stinging test. Digital images of the face of the subjects were also taken at each control time. Furthermore, the volunteers express their judgement on the efficacy and the pleasantness of the product by means of a self-assessment questionnaire.
This will be a double-blind, randomized, three-arm parallel groups study of the effect of toothpastes containing Ca-hydroxyapatite (HAP), Mg-Zn-hydroxyapatite (Zn-Mg-HAP), or fluoroapatite (FAP). The aim of the study is to compare the effect of toothpastes containing Ca-hydroxyapatite (HAP), fluoroapatite (FAP), and Mg-Zn-hydroxyapatite (Mg-Zn-HAP) on dentin hypersensitivity associated with dental abrasion. Materials and methods. Thirty consent patients aged 35-45 with dentin hypersensitivity associated with abrasion will be recruited for the study. The study will have 2 phases: preparatory phase (recruitment of the patients, standardization of their oral hygiene protocols, wash-out period, calibration of the researchers and training) and the main part (double-blind, randomized, parallel groups study of toothpastes effect). Patients will be randomly divided into 3 groups (group 1 - toothpastes with Ca-HAP, group 2 - toothpastes with Zn-Mg-HAP, group 3 - toothpastes with FAP). Clinical examination will be performed at the baseline, after 2 and 4 weeks, and will include patient's interview, oral hygiene level assessment (OHI-S), and dentin sensitivity testing (Shiff's index). The null hypothesis is that there will be no statistically significant differences in dentin sensitivity level between the study groups.
Data and specimens will be collected longitudinally from patients seen in the UVA Interstitial Lung Disease (ILD) clinic in order to describe the phenotypic expression of various interstitial lung diseases. Samples will also be collected from a control group for comparison purposes. All data will be entered into a repository for future research purposes or screening for new studies that become available. This data will help identify trends and hopefully lead to a better understanding of the disease progression, treatment options, and outcomes.
Nutricia wants to launch a real-life study, to see how the presence of prebiotics and probiotics in the boosted protein hydrolyzate can improve symptoms in the first weeks of use, and supplement the efficacy and safety data of the drug. formula, collected during clinical trials, with real life use. The target population will be children with a definite or suspected diagnosis of APLV, who have never taken a hypoallergenic formula, for whom the doctor decides to prescribe the Pepsicate Syneo formula, regardless of the clinical manifestation of the allergy. These children will be included before the age of 8 months and will be seen again 4 weeks after the prescription. The data from this real-life study will also better characterize the profile of infants taking Pepsicate Syneo. Finally, the perception of the formula by the parents will be collected.
Pain can currently be quantified using quantitative sensory tests (QSTs). However, we lack knowledge concerning how relational and contextual factors impact these quantitative tests. We will examine how a standard QST battery is affected by "removing" the social and human interaction from the test session compared to usual QST testing where the participant is guided through the assessment by a research assistant. Our objectives are: 1. How is the QST affected when guided by a research assistant compared to guided by a computer 2. Does the level of the assessor's empathy affect the QST outcome 3. How do psychological factors affect the QST testing 4. are these outcomes affected by the patient profile (low back pain patients vs healthy controls)
