Short-course radiotherapy combined with immunotherapy may bring revolutionary changes to the preoperative neoadjuvant treatment mode for locally advanced rectal cancer.In view of the shortcomings of the current preoperative neoadjuvant treatment model for locally advanced rectal cancer, we will explore the feasibility of a new model of short-course radiotherapy combined with immunotherapy, and develop a possible optimal plan based on the existing theoretical basis, namely "short-course radiotherapy + PD-L1 monoclonal antibody combined with CAPEOX chemotherapy for 2 cycles", and explore the efficacy and adverse effects of this model. The study will also attempt to explore the characteristics of the treatment beneficiary population, explore the characteristics of the treatment beneficiary population by multi-dimensional tumor and microenvironmental information through multi-omics sequencing analysis, attempt to build an efficacy prediction model, early screening of the treatment beneficiary population for precise treatment, and thus explore a new model of radiotherapy combined with immunotherapy.
Hypertension is the most common complication in patients with diabetes nephropathy. Strengthening blood pressure and blood sugar control is the basic treatment for patients with diabetes nephropathy. Angiotensin receptor blocker (ARB) and angiotensin-converting enzyme inhibitor (ACEI) are the first line drugs recommended in domestic and international guidelines for diabetes patients to control hypertension. As a new ARB drug, azilsartan has been found to have better antihypertensive effect than other ARB drugs. However, due to the limited sample size and study time, azilsartan has no significant advantage over other ARB drugs in terms of renal protection effect, and has not been systematically studied in diabetes nephropathy population. This study is intended to evaluate the effect of azilsartan on proteinuria and blood pressure improvement in patients with diabetes nephropathy and hypertension through clinical randomized controlled study, so as to accumulate evidence-based evidence of azilsartan in the comprehensive management of heart and kidney protection in this group of people, and promote the development of comprehensive treatment for patients with metabolic disease and renal injury combined with hypertension. This study will compare the advantages and disadvantages of azilsartan and classical ARB drug losartan potassium in terms of proteinuria, blood pressure control and renal function protection in patients with diabetes nephropathy and hypertension; We propose that the main indicator is the change of urinary albumin/creatinine ratio relative to the baseline, and the secondary indicator is the change of 24-hour urinary protein relative to the baseline; Change of blood pressure relative to baseline; Renal function, electrolyte and blood glucose.
This study seeks to compare two methods of trapeziectomy for basilar thumb arthritis. The first is trapeziectomy with ligament reconstruction and tendon interposition, which means removing the trapezium bone and filling the void with a tendon graft. This is the most commonly used procedure and the control group. The experimental group is trapeziectomy with suture tape suspension of the 1st metacarpal to the 2nd metacarpal. This is using a device called the InternalBrace, produced by Arthrex.
In patients with acute hypoxemic respiratory failure whose diagnosis is not established after initial evaluation, obtaining a histopathological diagnosis may improve the patients' prognosis. In our previous retrospective-controlled study, transbronchial lung cryobiopsy (TBLC) can lead to an increased chance of establishing a diagnosis compared with transbronchial lung biopsy (TBLB), with an acceptable safety profile. Therefore, further prospective randomized controlled studies exploring whether TBLC leads to improved prognosis for such patients are warranted.
Acute respiratory failure (AFR) is a serious condition that requires prompt and appropriate intervention to prevent further deterioration and improve outcomes. Bronchoscopy is a commonly used diagnostic and therapeutic procedure in patients with respiratory failure. However, traditional low-flow oxygen supplementation during bronchoscopy may not provide adequate oxygenation and ventilation, leading to complications and worsening of the patient's condition. High-flow nasal cannula therapy has improved oxygenation and ventilation in critically ill patients, making it a promising alternative to traditional oxygen supplementation during bronchoscopy. The bronchoscope is passed through the nose during all procedures in our center. HFNC oxygen therapy is applied to both nostrils. The bronchoscope occupies one of the nares receiving oxygen therapy during bronchoscopy. As a result, the application of HFNC needs to be optimized. Therefore, the investigators designed a modified HFNC with a single cannula. However, limited data exist on the safety and efficacy of modified HFNC therapy in patients with respiratory failure undergoing bronchoscopy. Therefore, the aim of this study is to evaluate the impact of modified HFNC therapy on the outcomes of undergoing bronchoscopy in patients with ARF. The findings of this study will contribute to understanding the role of modified HFNC therapy in managing ARF and inform clinical practice.
The investigators aimed to investigate the deep learning model to predict intraoperative hypotension using non-invasive monitoring parameters.
Acute Respiratory Distress Syndrome (ARDS) is a highly lethal disease with limited treatment options. In recent years, prone position ventilation has been shown to improve the mortality rate and lung injury of ARDS patients by promoting lung recruitment, improving ventilation/perfusion (V/Q) ratio, enhancing respiratory system compliance, promoting sputum drainage, and effectively avoiding overinflation of the dorsal lung. Electrical Impedance Tomography (EIT) technology has been used to evaluate the effect of prone position ventilation on lung V/Q matching, and some studies have confirmed that prone position ventilation can improve lung V/Q matching and oxygenation index. However, previous studies were mostly case reports or small-sample physiological studies that lacked dynamic changes in lung V/Q matching during repeated prone position ventilation. Therefore, this study hypothesizes that prone position ventilation can increase lung V/Q matching in ARDS patients, and its improvement is correlated with changes in oxygenation index, invasive ventilation time, and patient prognosis. Repeated prone position ventilation can maintain lung V/Q matching at a higher level, no longer affected by changes in body position, which can accelerate pulmonary function recovery and improve the prognosis of ARDS patients.
this clinical trial aims to prove that multiple injections will produce a steady rate of acceleration of orthodontic tooth movement.
This study aims to decrease cancer survivors' intrusive ruminative thoughts and cancer-related fatigue and increase their purposive ruminative thoughts and psychological resilience. In this context, an online (Zoom) 10-session empowerment program based on the literature will be implemented for cancer survivors.
Spinal Muscular Atrophy (SMA) is caused by the homozygous loss of the Survival Motor Neuron (SMN) 1 gene, which leads to degeneration of spinal alpha-motor neurons and muscle atrophy. Three treatments have been approved for SMA but the available data show interpatient variability in therapy response and, to date, individual factors such as age or SMN2 copies,cannot fully explain this variance. The aim of this project is: - collect clinical data and patient-reported outcome measures (PROM) from patients treated with nusinersen, risdiplam, onasemnogene abeparvovec, - identify novel biomarkers and RNA molecular signature profiling, - develop a predictive algorithm using artificial intelligence (AI) methodologies based on machine learning (ML), able to integrate clinical outcomes, patients' characteristics, and specific biomarkers. This effort will help to better stratify the SMA patients and to predict their therapeutic outcome, thus to address patients towards personalized therapies.
