The aim of this project is to investigate: - The status of the central serotonin (5-hydroxytryptamine, 5-HT) system in compulsive behaviour and how it is affected by sub-chronic escitalopram administration - The mechanisms underlying how sub-chronic administration of escitalopram affects the central 5-HT system - How changes in cognitive performance, including the balance between habitual and goal-directed mechanisms, are affected in compulsive behaviour by boosting 5-HT function - How functional brain changes in cognitive function measured with magnetic resonance imaging relate to altered 5-HT function following escitalopram administration.
The current standard treatment for locally advanced rectal cancer is still fluorouracil-based neoadjuvant radiotherapy and chemotherapy followed by TME surgery, followed by adjuvant chemotherapy. Fluorouracil single-agent simultaneous sensitization of radiotherapy and chemotherapy has a pCR of about 15-20% and a tumor downgrade (ypStage 0-I) rate of about 35%. However, about 30% of patients still have distant metastasis, which is the main obstacle affecting the survival prognosis of patients with locally advanced rectal cancer. About 50% -65% of patients was still stage II-III after neoadjuvant therapy. The long-term follow-up shows that for patients with ypT4 after surgery, the 3-year DFS is about 50%. For patients with ypN2, the 3-year DFS is less than 40%. Therefore, it is necessary to strengthen postoperative adjuvant chemotherapy to improve the survival prognosis for these patients. Although FOLFOX adjuvant chemotherapy improved survival benefit than 5FU as adjuvant treatment in ypStage II-III patients after neoadjuvant treatment in ADORE trial. However, with the progress of neoadjuvant therapy research, more and more studies have proposed to move part or all of postoperative adjuvant chemotherapy to preoperative neoadjuvant therapy due to low compliance of adjuvant chemotherapy. During neoadjuvant treatment, induction chemotherapy with FOLFOX / CAPEOX or consolidation therapy after CRT with FOLFOX / CAPEOX had been investigated a lot. The pCR rate was 19% -38%, and the tumor downstaging rate was about 50%. Another 50% of patients still had ypstage II-III postoperatively. The 3-year DFS for ypStage III was only 55% even with FOLFOX as adjuvant chemotherapy. And for ypT4N0 patients with ypstage IIB-IIC, there is also a higher risk of recurrence and metastasis. And it is urgent to explore new treatment strategies to improve this part of patients Survival prognosis. For locally advanced colon cancer, surgery combined with postoperative adjuvant chemotherapy is currently the standard treatment mode for stage II-III colon cancer. About 30% of patients with locally advanced disease will relapse within 3 years, of which distant metastases are more common and eventually become the main cause of death of patients. For locally advanced colon cancer with a preoperative staging of T4b, the NCCN guidelines recommend surgery after neoadjuvant chemotherapy with FOLFOX or CAPOX regimens. In the FOxTROT study of neoadjuvant treatment of locally advanced colon cancer, for patients with T3> 5mm or T4, after 4 courses of neoadjuvant chemotherapy with FOLFOX regimen, 20.5% of patients still have T4 after surgery, and 15.2% of patients had N2 disease. For this part of patients, new postoperative treatment options should also be explored to improve patient survival and prognosis. In view of the high efficiency of the three-agent FOLFOXIRI regimen in advanced colorectal cancer and the success in adjuvant chemotherapy after pancreatic cancer surgery, 5FU, oxaliplatin combined with irinotecan may have a synergistic effect. At present, a phase III randomized controlled study (IROCAS study) in Europe is underway. For high-risk phase III patients, the mFOLFOXIRI regimen is compared with mFOLFOX6 regimen adjuvant chemotherapy. Based on the above reasons, our center plans to further carry out "multi-center, randomized, controlled phase III clinical study of mFOLFOXIRI versus mFOLFOX6 adjuvant chemotherapy after neoadjuvant oxaliplatin in locally advanced colorectal cancer." Improve the survival prognosis of postoperative high-risk colorectal cancer patients after neoadjuvant therapy.
Herpes Simplex Virus encephalitis is the most common infectious encephalitis, with an estimated annual incidence of 1 / 250,000 to 1 / 500,000 in industrialized countries. Despite a widely used antiviral treatment, the prognosis remains poor with a mortality of 5 to 20% and a considerable morbidity rate. One of the contributing factors of bad prognosis is the development of encephalitis mediated by autoantibodies, most often directed against NMDA receptors, in the weeks following viral encephalitis. The description of this pathology is recent, the pathophysiology of this process remains poorly understood, and the management of these patients is not yet codified.
Images will be collected during routine colposcopy and paired with their pathology results to be used for resident education
The primary objective of the study is to evaluate the days until reaching clinical stability after starting randomization in hospitalized patients with elevated inflammatory parameters and severe COVID-19 lung injury.
Evaluate HACOR socre utility and efficacy in predicting NIV and/or CPAP failure in patients with COVID-19 associated respiratory failure. Propose adaptations to HACOR score based on the "state of art" of COVID-19
Abstract The objective of this study is to review, through prospective case research, the efficacy of oral chlorine dioxide in the treatment of patients with COVID infection 19. The research will be carried out between April and June 2020 with a quasi-experimental design in two health care centers on a sample of twenty (20) patients, through direct intervention, who will measure the changes in the manifest symptoms of infection and negativity. a COVID 19 after administration of the study preparation, to determine the effectiveness of chlorine dioxide in the treated group. Based on the results that are found and on the evaluation of efficacy on the basis of clinical improvement on a scale of 1 to 5, and of the negativization of COVID 19, we can conclude whether the therapeutic efficacy in this investigation is considered good by verifying whether or not there is efficacy of treatment with chlorine dioxide in COVID 19. With this research, it is hoped to stimulate the search for new therapeutic options in the treatment of COVID 19 and contribute to the development of NEW options in medications, considering the immense number of deaths and morbidity that currently exists in the present pandemic. Key words: COVID 19, chlorine dioxide, treatment.
The novel coronavirus (COVID-19) emerged in December 2019, and in mere months has spread to more than 104 countries, resulting in an outbreak of viral pneumonia worldwide. Current local quarantine policy in Hong Kong for individuals suspected for COVID-19 requires daily self-reported symptomatology and body temperature, given the intermittent nature and the high dependency of self-discipline undermine the practicality of the approach. To date, the advance in sensor technology has made possible to continuously monitor individual physiological parameters using a simple wearable device. Together with the mobile wearable technology that allowing instantaneous, multi-directional, and massive data transfer, remote continuous physiological monitoring is made possible. The Cardiology division, the Univeristy of Hong Kong has been in collaboration with Biofourmis to implement such technology for remote heart failure management. Similar digital therapeutic system can be applied to remotely monitor physiological parameters of large number of quarantined or suspected COVID-19 at home or in quarantine facility. It is purposed to allow the monitoring team to effectively and remotely monitor COVID-19 quarantined and patients, manage and evaluate the disease progression.
The prone position consists of placing the patient on his or her stomach with the head on the side, during sessions lasting several hours a day and could help spontaneous ventilate the patient.
The efficacy of HIPEC in prevention of local recurrence, distant metastasis or peritoneal metastasis in locally advanced gastric cancer is not definite. The hypothesis of the trial is that radical gastrectomy combined with HIPEC is superior to only radical gastrectomy in terms of overall survival.
