Clinical Study on the Safety of Double and a Half Layered Esophagojejunal Anastomosis in Curative...

Surgery--Complications

Surgical resection remain the main means for gastric cancer. With the improvement of surgical techniques and concepts, the incidence of postoperative complications gradually decreased, but esophagojejunostomy complications occur frequently. Studies have showed that the risks of esophagojejunostomy leakage related to old age, obesity, malnutrition, neoadjuvant radiotherapy and chemotherapy, and the incidence rate was 1%-16.5%. The incidence of anastomotic leakage varies greatly, which suggests that effective preventive measures can reduce the probability of anastomotic leakage. In addition to the patient factors, the technique and experience of the operator are also important to reduce anastomotic leakage. The safety of esophagojejunostomy depends on the integrity of the anastomosis, sufficient blood supply and satisfactory tension. Early tight mucosal anastomosis and the proliferation of mucosal epithelial cells can reduce the stimulation of digestive fluid to the anastomotic wound. However, there are some problems in the operation: 1. When esophagojejunostomy is completed with tubular stapler, it is the contraposition of the plasma muscular layer of the digestive tract; 2. Because of the different diameter of esophagojejunostomy and tissue hypertrophy, the internal mucosa layer of the anastomosis is often torn or the residual tissue is embedded in the anastomosis, which affects the healing of the anastomosis. Double and a half layered esophagojejunal anastomosis was proposed to improve the safety of anastomosis. The procedure is as follows: after the end of esophagojejunostomy, 3/0 barbed suture or absorbable suture was used. First, the anastomotic site was sutured continuously for one circle, with the suture spacing of 3-4 mm and the width of 4-5 mm. Then, the continuous horizontal mattress type seromuscular layer varus suture was used to embed the anastomotic stoma for one circle, and the suture width was 5-8 mm above and below the anastomotic stoma. After the completion of esophagojejunostomy, the full-thickness reinforcement of the anastomosis and the embedding of the seromuscular layer can ensure the complete anastomosis of the mucosal layer of the anastomosis. The embedding of the seromuscular layer can also improve the anti-pressure and anti-tension of the anastomosis, and provide a guarantee for the primary healing of the anastomosis.

A Phase 2/3 Study of Efgartigimod PH20 SC in Adult Participants With Bullous Pemphigoid (BALLAD)...

Bullous Pemphigoid

ARGX-113-2009 is an operationally seamless 2-part, phase 2/3, prospective, global, multicenter, randomized, double-blinded, placebo-controlled study to investigate the efficacy, safety, tolerability, immunogenicity, participant-reported outcome measures (including those assessing participant QoL), PK, and PD of efgartigimod PH20 SC administered via subcutaneous (SC) injection in adult participants with moderate to severe BP. This study intends to demonstrate that efgartigimod is an effective and safe treatment for BP, providing participants with control of disease activity (CDA) and eventually remission while reducing their cumulative exposure to OCS. study will consist of 2 parts: Part A of the study is a phase 2 evaluation that intends to provide proof of concept for the therapeutic activity of efgartigimod PH20 SC in participants with BP. Part B of the study is a phase 3 evaluation that intends to confirm the results obtained from part A in a separate, larger group of participants with BP. An interim analysis will be performed during part A (on data obtained through week 26 for all Part A participants) to assess the primary endpoint and several secondary endpoints, confirm the appropriate sample size for part B of the study, and determine whether the efficacy results observed through week 26 of part A warrant continued study of efgartigimod PH20 SC for the treatment of participants with BP (futility analysis). Other than differences in main goals, endpoints, and statistical analyses, parts A and B are identical in schedule, structure, assessments, and conduct.

Family Involvement in Treatment for PTSD (FIT-PTSD): A Brief, Feasible Method for Enhancing Outcomes,...

Posttraumatic Stress Disorder

Although effective treatments for PTSD exist, high rates of treatment dropout and sub-optimal response rates remain common. Incorporating family members in treatment represents one avenue for improving outcomes and providing Veteran-centered care, and surveys of Veterans in outpatient VA PTSD care indicate that 80% desire family involvement. The VA has invested many years and millions of dollars on the dissemination of Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE) for PTSD. A family-based intervention that complements these two first-line treatments would capitalize on existing treatment infrastructure while also potentially boosting outcomes and retention. Preliminary testing of the proposed Brief Family Intervention (BFI) resulted in 50% less dropout from CPT/PE among Veterans whose family members received the BFI. There was also a large impact on PTSD symptoms at 16 weeks (d = 1.12) in favor of the BFI group. The goal of this study is to test the effectiveness of the BFI among a fully-powered sample. One hundred Veteran-family member dyads (n = 200) will be recruited. Veterans will be beginning a course of usual-care CPT or PE at one of two VA sites. Family members will be randomized to receive or not receive the BFI, a two-session psychoeducational and skills-based protocol. PTSD symptom severity and treatment retention will be the primary outcomes. Assessments will be conducted by independent evaluators at baseline, 6-, 12-, 18-, and 26-weeks. Veterans whose family members receive the BFI are expected to have lower dropout and a greater rate of change in their PTSD symptoms compared to Veterans whose family members do not receive the BFI. If the BFI is found to increase the effectiveness of and retention in CPT/PE, it will be a highly appealing option for incorporating families into Veterans' PTSD care.

Feasibility Trial of a Mindfulness Based Intervention in Youth With Type 1 Diabetes

type1diabetes

Type 1 diabetes (T1D) is one of the most common chronic illnesses of childhood. The involved treatment regimen, including daily insulin administration/pump management, frequent blood glucose checks, and careful track-ing of food intake, places a high-stress burden on patients and their families. Adolescence is a particularly risky time for T1D management given a marked decline in treatment adherence and glycemic control. Over 80% of adolescents with T1D have poor glycemic control (A1c >7.5%), and one significant risk factor is the increase in negative affectivity, including depression and anxiety symptoms, that distinguish adolescents with T1D. Elevated depression and anxiety symptoms affect 40% of teens with T1D. Preliminary data support the notion that negative affectivity contributes to diminished treatment adherence and worsening of glycemic control, partially through the effects of negative affectivity on stress-related behavior such as maladaptive eating behavior (e.g., dietary restriction, uncontrolled eating patterns, and insulin omission for weight control). Unfortunately, there is no gold-standard approach to address the poor glycemic control seen in adolescents with T1D. The creation of novel, targeted interventions, tailored for the developmental needs of adolescents with T1D and the particular burdens of coping with their chronic illness, are needed. Mindfulness-based interventions delivered to adolescents without T1D, including the team's preliminary work in teens with depression and weight-related disorders, have shown promise in treating negative affectivity, maladaptive eating behavior, and health outcomes. A mindfulness-based approach may be well-suited for adolescents with T1D, but given that the mechanisms of association among negative affectivity, stress-related behavior, and self-care are unique to individuals with T1D, interventions must be specifically tailored for this population. The goal of this study is to, therefore, adapt an existing 6-session mindfulness-based intervention, Learning to BREATHE, for use with adolescents with T1D (BREATHE-T1D). The first specific aim of the study is to adapt BREATHE for adolescents with T1D and to adapt a relevant and credible health education comparison curriculum (HealthEd-T1D). The second aim is to carry out a 2-way pilot randomized controlled trial to evaluate the feasibility and acceptability of BREATHE-T1D and HealthEd-T1D. The result of the current study will be a feasible and acceptable mindfulness intervention and comparison curriculum that can be evaluated in an efficacy trial. The multidisciplinary study team contributes complementary areas of expertise in adolescents with T1D, behavioral intervention development, negative affectivity and maladaptive eating behavior, adolescent mindfulness-based intervention, qualitative data analysis, and delivery of behavioral health interventions via telehealth. The study's innovative approach will enable the investigators to establish a feasible/acceptable intervention tailored for adolescents with T1D, leading to a future proposal for a full-scale efficacy trial.

Bone Graft Cultivation by Periosteal Elevation

Periosteal Elevation

Bone Graft Cultivation is a two-stage procedure aiming at generating new bone tissue for grafting by periosteal elevation . The first stage is the insertion of space-occupying implant which is responsible for keeping periosteal elevation for a defined time to stimulate new bone formation. The second stage is the extraction of woven bone that has been formed together with the implant. A sufficient amount of biologically highly valuable woven bone may be produced and harvested for bone grafting using periosteal elevation method. The concept of using periosteal elevation to cultivate bone has never mentioned in orthopedic literature. Thus, this study aims to present an original experimental Interventional (Clinical Trial) on 18 skeletally immature patients. The purpose of this non-comparative study is to test, for the first time, possibility of generating bone tissue from iliac bone and to test the bioactivity of this new "Bone Graft Material" in fillings of losses of osseous substance from various origins, such as traumatic, infection, and benign tumoral causes. Study protocol: Participants will be randomly assigned preoperatively into three surgical groups depending on cultivation time: early-stage group, medium-stage group and late-stage group . The newly bone formed bone will undergo tissue processing, and then, bone volume/tissue volume ratio, osteoid volume/tissue volume ratio, and osteocyte count per high-power field will be analyzed. In addition to histological examination, micro-CT scanning and osteoinductive factors ( bone morphogenic protein (BMP2), Fibroblast growth factor-2(FGF2), Transforming Growth Factor(TGFB1), and Insulin-like growth factor(IGF1)) assessment will be done as well
