The rationale for this retrospective study is to evaluate the efficacy and safety of thrombopoietin-receptor agonist (TPO-RA) romiplostim for reducing thrombocytopenia and bleeding tendency in pediatric participants with genetically confirmed Wiskott-Aldrich syndrome (WAS).
Vitamin D (VitD) deficiency is a significant public health concern in many areas around the globe which has been associated with many immune-mediated diseases, including asthma. Severe asthma has been linked with a decreased glucocorticoid receptors (GR) ratio (GR-α/ GR-β ratio), indicating steroid hyporesponsiveness. Using combined in silico and in vivo approaches, aimed to explore the immunomodulatory effect of VitD on asthmatic patients diagnosed with hypovitaminosis D.
The project "More Appreciation and Less Criticism Project" (MALC) is a collaboration between the Tung Wah Group of Hospitals (TWGHs) and the School of Public Health of The University of Hong Kong (HKUSPH), funded by The Hong Kong Jockey Club Charities Trust. The objectives are to develop and test theory-driven group programmes to increase parents' intention and actual behaviours to express more appreciation or less criticism when interacting with their children, thereby enhancing family harmony and happiness.
Social emotional competence is instrumental to children's health and development. The preschool edition of Promoting Alternative THinking Strategies (PATHS®) intervention was tested in this study. PATHS® is a universal teacher implemented, and school-based intervention. In the first years of this study, PATHS® which was originally developed in the United States was adapted for a Swedish preschool context according to a theoretical model for intervention cultural adaptation entitled the Planned Intervention Adaptation (PIA) protocol. After the cultural adaptation process, a two-wave pre-posttest randomized controlled trial of PsPATHS was conducted with Swedish preschool aged children. Implementation data were collected and outcome evaluation results are being finalized at the time that this protocol is being submitted in August 2020.
Pedicled jejunal flap can be utilized with various tips for esophageal reconstruction in patients with a history of gastrectomy, or those who have undergone synchronous esophagogastrectomy, although the rate of anastomosis leakage is high with this technique. Therefore, in the current study, we considered the utility of the evaluation of blood flow of the remnant esophagus with indocyanine green in setting the anastomosis site. We included 50 patients who underwent radical esophagectomy with pedicled jejunal flap between April 2012 and June 2020. From June 2019, the blood flow of not only the pedicled jejunum, but also the remnant esophagus were evaluated in order to set the anastomosis site of the latter because the color was not definitive criteria for judging in surgery on the remnant esophagus. Usually, the second and third jejunal vessels are transected, and if the jejunal flap cannot reach to the anastomosis point, we actively transect the marginal vessels in order to stretch the jejunal flap. Microvascular anastomosis between the jejunal branches (the second) and the internal thoracic vessels is usually made, and the anastomosis site is set at the part of the esophagus that is well-dyed with indocyanine green. A total of 39 patients underwent the procedure prior to June 2019 ( Group A), and 11 patients underwent the procedure as of June 2019 (Group B). No significant difference was found in the patients' background, type of preoperative therapy, and presence or absence of ligation of marginal vessels and two-stage operation between the two groups. Group A had 16 cases of anastomosis leakage, while Group B only has one (P < 0.05). There were no cases of significant pedicled jejunum graft necrosis. Our findings demonstrate that the evaluation of the blood flow of the remnant esophagus during setting of the anastomosis site may decrease the rate of anastomosis.
Intestinal transplantation is associated with high numbers of ejection events. A close endoscopic controll of the intestinal graft is possible. Sasaki et al. presented 2002 an endoscopic score using zoom-endoscopes for early detection of rejection events.
Though Cardiac surgery under cardiopulmonary bypass (CPB) under epidural anesthesia in conscious patients is associated with increased risk of epidural hematoma. The investigators developed a monitored anesthesia care (MAC) platform for cardiac surgery under CPB. In the current prospective study, the investigators investigated the safety and effectiveness of the MAC platform versus intubated general anesthesia (IGA) in patients receiving elective open-heart surgery. The study included adult patients who were scheduled to undergo open-heart surgery under CPB at Shuguang Hospital between April 2012 and December 2021. MAC consisted of local anesthesia at the site of sternotomy, sedation with dexmedetomidine, analgesia with remifentanil/sufentanil and electroacupuncture. MAC versus IGA was chosen by the patients. The investigators will investigate the safety and effectiveness of the MAC platform versus IGA in patients receiving elective open-heart surgery.
Periodontitis patients, 40 cigarette smokers and 40 non-smokers (defined by cotinine measures in serum), were recruited to this double arm prospective cohort study. Data were collected 3 months following non-surgical and surgical periodontal treatment, and following 12 months with supportive periodontal therapy. Data collected were clinical attachment level, probing depth, bleeding on probing,oral bacteria, serum, blood (PAXgeneBlood), and gingival crevicular fluid.
Laparoscopic Nissen fundoplication (LNF) is a surgical intervention for gastroesophageal reflux disease (GERD); however, it can be followed by recurrent symptoms or complications that may affect patient satisfaction. Intraoperative endomanometric evaluation of esophagogastric competence and pressure, combined with LNF in patients with large sliding hiatus hernia (>5cm) with severe GERD (DeMeester score >100), is needed.This is a retrospective, multicenter, comparative study. Baseline characteristics, initial reflux symptoms, preoperative and postoperative antacid medication use, postoperative complications (dysphagia and gas bloat syndrome), recurrent symptoms, and satisfaction were collected from a prospective database. Outcomes measures were recurrent reflux symptoms, postoperative side-effects, and satisfaction with surgery. Quantitative data were compared between the studied groups using the independent t-test or Mann-Whitney U test for normally and non-normally distributed numerical variables, respectively
In frail patients with external full-thickness rectal prolapse (FTRP), the exact postoperative recurrence and functional result outcomes difference between Laparoscopic ventral mesh rectopexy (LVMR) and perineal stapler resection (PSR) have not been investigated, leading to ineffective treatment. Objectives: Evaluating the efficacy of PSR versus LVMR for treating external FTRP in the elderly. Design: This was a retrospective study that involved multiple centers. Settings: This study was conducted in the colorectal surgical units of our Universities' Hospitals Patients: 330 elderly patients divided into LVMR group (250), and PSR (80) between April 2012 and April 2019. Before and after surgery, patients were evaluated using the Wexner Incontinence Scale, the Altomare Constipation Scale, and the patient's satisfaction. Main outcomes measurement: The primary outcome was the recurrence rate and risk factors of FTRP. Secondary outcomes were postoperative incontinence and constipation and patients' satisfaction.
