Filter by:Transbronchial cryobiopsy under the guidance of endobronchial ultrasound is performed in patients with pulmonary peripheral nodule, and assess the diagnostic yield and safety.
The aim of this study is to prospectively validate the safety and efficiency of management according to the YEARS algorithm to safely rule out clinically suspected PE in patients with active malignancy to be compared with 'standard' management by computed tomography pulmonary angiography (CTPA) alone in a randomized study.
This experiment is designed to analyze the metabolites in body fluids from patients with active tuberculosis and latent tuberculosis infection also with health volunteer, then combine the metabolic product features with clinical characteristics, to develop a kind of metabolites targets to evaluate the progress in tuberculosis, thus provide a basis for further utilization of humoral metabolites in the diagnosis of tuberculosis.
Serious pneumonia is a serious inflammation of the lungs caused by various pathogens, resulting in severe bacteraemia or toxemia, which in turn causes blood pressure drop, shock, blurred consciousness, restlessness, delirium and coma, etc., and requires intensive care and treatment in intensive care unit (ICU) because of its seriousness. There is an upward trend in the number of clinically immunosuppressed host patients, including long-term use of glucocorticoids for rheumatoid immune diseases and kidney diseases, tumor chemotherapy, organ transplantation, etc. A huge risk for these patients is the diagnosis and treatment of infections, especially lung infections. We have previously observed a significant increase in mortality from severe pneumonia in immunosuppressed patients, and our recent analysis of 204 patients with novel coronavirus pneumonia found that low lymphatic counts, immunosuppression, etc. were independent risk factors for death in patients. Early diagnosis and timely treatment are the main means to reduce the mortality rate of severe pneumonia. CD55 is an important complement regulatory protein that inhibits C3 and C5 activation by blocking the formation and accelerating the decay of new C3 and C5 convertases, both of which mediate the downstream action of all three complement activation pathways, and CD55 protects host cells from complement attack. Our previous study found that CD55 was significantly elevated in patients with severe pneumonia. Therefore, this project proposes "Early diagnosis of severe pneumonia based on combination of biomarkers with new generation pathogenesis and early clinical manifestations". It is proposed to validate the predictive effects of recently discovered markers such as CD55, HBP and CD64 on severe pneumonia through prospective single-center clinical studies, explore the establishment of new predictive models for early diagnosis of severe pneumonia, and optimize the diagnosis and treatment strategy of severe pneumonia, and provide new ideas for accurate treatment of severe pneumonia.
The performance of 3 different sampling methods (2 nasopharyngeal swabs, 1 oropharyngeal swab) for the detection of SARS-CoV-2 with real-time reverse transcriptase polymerase chain reaction will be compared.
BACKGROUND: The diagnosis of pancreatic adenocarcinoma (PDAC) in many cases is completely unforeseen by the patient, who often faces a disease that is already at an advanced stage, with poor prognosis. The clinical visit during which the diagnosis is communicated together with the first information regarding the planned treatments is of paramount importance. It is hypothesized that the clarity of such information is able to influence patients's engagement and thus the compliance. AIMS: The aim of this study is to collect quantitative data on the level of PDAC patient engagement and the rate of understanding of the information received from the doctor, and investigate the possible association between these two variables and with the patient's level of compliance. METHODS: This is a single-center, observational, cross-sectional cohort study focused on patients diagnosed with PDAC, approved by the Ethics Committee of the San Raffaele Hospital. As no preliminary data are available on the association between PDAC patient's understanding rate and their level of engagement and of compliance no power calculation is possible. This is a pilot study, aimed at enrolling at least 45 PDAC patients during a 3 months frame. CONCLUSION: COMMUNI.CARE will be the first study specifically investigating whether there is a relation between PDAC patients' rate of understanding, their engagement and compliance at time of diagnosis.
The ankle and/or foot injuries incidence is high. Lateral ankle sprains are most common diagnosis, while fractures represent less than 15% of final diagnosis. Ankle and/or foot injuries are associated with significant morbidity in terms of pain and chronic instability. The societal cost of these injuries is significant mainly related to hospital care and sick-leave. In summary ankle and/or foot injuries are very frequent reason for emergency admission. The study hypothesis is that an accelerated nursing care system for traumatized ankle and/or foot patients is feasible and allows patients to be cared for in accordance to current medical recommendations. Such a branch should be followed by a return to work and sports within a time frame consistent with the literature. The duration of patient management in emergency department should be short, less than that observed in a historical cohort. Finally patient satisfaction should be high. In the medium term, the implementation of an accelerated nursing branch for the diagnosis and treatment of ankle and/or foot injuries should contribute to effective care and reduction of over activity in emergency departments.
Vertigo is a common complaint in the Emergency Department (ED). The differential diagnosis of central and peripheral vertigo is a difficult issue that directly affects mortality. Magnetic resonance imaging (MRI) is the preferred diagnostic tool, but may not be suitable in all patients due to logistic and economic conditions. In this study, the investigators evaluated the role of thiol/disulfide homeostasis (TDH) parameters and ischemia modified albumin (IMA) levels to assist in the value of being used instead of MRI.
In this study, a prospective, randomized and controlled clinical study would be carried out to establish Ultrasound Integrated Precision Diagnosis Technology with elastography as the core technology to evaluate renal injury and repair comprehensively and accurately, and to improve the clinical diagnosis chance of renal injury (or renal fibrosis). Combined with the dynamic changes of biomarkers (inflammatory factors, cytokines secreted by immune cells, etc.) after kidney injury, the research on the prognosis of kidney disease with ultrasound elastography technology as the core would be explored, which aims to provide a scientific basis for the application of Ultrasound Integrated Precision Diagnosis Technology.
Under-diagnosis of TB in children is a critical gap to address. The INPUT study is a multinational stepped-wedge cluster-randomized intervention study aiming to assess the effect of integrating TB services into child healthcare services on TB diagnosis capacities in children under 5 years of age.
