Color change is a useful marker for the endoscopic identification of chronic atrophic gastritis (CAG) and gastric cancer (GC). Several histopathological studies have suggested a correlation between certain gastrointestinal lesions and intramucosal vascularity. The aim of this study is to investigate the association between the color and mucosal microvascular density of CAG and early GC using linked color imaging (LCI). In this study, Lesions diagnosed as CAG and early GC will be observed using LCI. In each image, the color values of atrophic and non-atrophic mucosa, as well as cancerous and non-cancerous mucosa, will be quantified using the International Commission on Illumination 1976 (L∗, a∗, b∗) color space. Histological microvascular density in biopsy or resected specimens will be evaluated using CD31 immunostaining. Color differences at the atrophic border and cancerous border, defined as Euclidean distances of color values between the atrophic and non-atrophic mucosa, as well as cancerous and non-cancerous mucosa, will be calculated according to mucosal microvascular density.
The purpose of this study is to characterize the disease progression of confirmed OPA1 mutation-associated autosomal dominant optic atrophy (ADOA) by evaluating the changes in ocular structural and functional outcomes.
Evaluation of computer guided placement of Zygomatic implants utilizing intra sinus versus extra sinus surgical approach for the reconstruction of atrophic maxilla. The expected benefit from the current study is to select the most suitable approach for Zygomatic implant placement with the least postoperative complications
The goal of this clinical trial is to evaluate the efficacy of the lateral sinus lift procedure using the tunnel technique flap in comparison to the traditional lateral sinus lift in partially or totally edentulous patients with loss of teeth in the maxillary premolar or molar areas and severe alveolar atrophy. The primary questions it aims to answer are: 1. Is the tunnel flap technique more suitable for lateral sinus lift than the trapezoidal flap technique in terms of post-operative symptoms? 2. Is the tunnel technique safer and more effective than the trapezoidal flap technique in terms of complication rate and the effectiveness of bone grafting? Participants will undergo the lateral sinus lift procedure using the tunnel technique, which involves making a vertical anterior incision. Patients will receive follow-up care, including phone contact the day after the procedure to detect any issues, and they will keep a diary during the week after surgery to record visual analog scale (VAS) pain values and analgesics taken. Follow-up surgical visits will be scheduled for suture removal and at 30 days after suture removal. After 6 months, dental implants will be inserted, and prosthetic rehabilitation will take place 6 months later. Implants will be monitored for up to 12 months after prosthetic rehabilitation. Researchers will compare the outcomes of tunnel flap technique lateral sinus lift with the trapezoidal flap sinus lift.
The goal of this clinical study is to evaluate the effects of a personalized symptomatic treatment plan integrated with monthly telemedicine and mobile palliative care interventions on a population of individuals diagnosed with Multiple System Atrophy (MSA) and their informal caregivers. The aim is to improve the quality of life of MSA patients and their caregivers, as well as provide them with better support during the disease progression. After a baseline visit, all 46 patients will receive a personalized therapeutic plan (including medical treatment, physiotherapy, logotherapy and occupational therapy excercises and psychological support) and contact with social workers and a palliative care team. They willl then be re-evaluated at 6-,12-, 18- month visits. Semi-structured online interviews at baseline and 12 month visit will collect patients' individual healthcare preferences, which will be taken into account in the preparation of the individual therapeutic plan. Twenty-three patients will be randomized to receive monthly telemedicine visits. Assessment of patients´satisfaction with the therapeutic plan, with the palliative interventions (when they occurred) and the telemedicine visits will be carried over the 18 month period. Forty-six informal caregivers will be invited to participate with semi-structured online interviews and assessment of their QoL and caregivers' burden.
An interventional prospective randomised clinical trial (RCT) in parallel groups is planned. The sample size was 30 patients who will be randomly divided into two groups based on the surgical procedure. The first group is the healing of the donor zone after SCTG harvesting without filling the wound with collagen matrix. The second group is the wound defect closure in the donor area using the collagen matrix "FibroMATRIX" (LLC "Cardioplant", Russia; registration in Russia 20/05/2019 No FSZ 2019/83671). Changes in volumetric parameters of the maxillary tuberosity area after CTG harvesting, severity of pain, postoperative edema, bleeding, analgesic intake and quality of life in the postoperative period will be assessed.
Recently, few studies have attempted to test the regenerative effects of human insulin application by microneedling on atrophic scars versus other topical preparations. However, the scars were limited etiologically to acne scars. In addition, a lack of inclusion of a control group instead of comparing topical preparations with insulin was also a limitation to these studies. A control group consisting of microneedling alone would have served as a better comparison in order to determine whether the effects of microneedling are augmented by topical protein-rich preparations.
A long-term safety study in Brazilian patients with a confirmed diagnosis of Spinal Muscular Atrophy (SMA) treated with Onasemnogene Abeparvovec (Zolgensma®)
This is a Phase 1/2 Study to Assess the Safety and Efficacy of OCU410 for Geographic Atrophy Secondary to Dry Age-Related Macular Degeneration (AMD). This is a multicenter study, which will be conducted in two phases and will enroll up to a total of 63 subjects.
