Filter by:Tonsillar tissue is a significant organ for the performing of immune systems in children. The Endoplasmic Reticulum (ER), is an organelle needed for the care of a stable function of the cells. The purpose of the study was to explore the correlation among ER stress and tonsillar tissue disorders and to explain the structure of diseases related to the immune system.
The impact of the environment on human health is considerable. An important factor is the effect of temperature on the human body, where either the effects of short-term exposure to extreme temperatures (cryotherapy, sauna, etc.) or the long-term environmental impact are monitored. The study was focused on research of the long-term effect of repeated CWI on atherogenesis, lipid parameters and fat distribution.
Pancreatitis is a common complication especially in patients with gallbladder stones, most patients with biliary pancreatitis may recover spontaneously without sequelae, but in 10-20% of patients, the disease is severe and mortality rates of up to 30% are detected in these patients. In the evaluation of acute biliary pancreatitis, many scoring systems have been established (Atlanta, Ranson, APACHE, BISAP etc.) from past to present to determine morbidity and mortality of the disease. In this study, the investigators aimed to evaluate the correlation between morbidity and mortality of acute biliary pancreatitis and lymphocyte subtypes with Flow-cytometry.
Data show that the coronavirus disease 2019 (COVID-19) symptoms can be severe in 4% and 3% of the adolescents aged 11-15 years and ≥ 16 years, respectively. In addition, the prevalence of chronic diseases among adolescents has increased in the last years. About 20% of the adolescents have some chronic disease, resulting in increased morbidity and mortality. In march, 2020, the quarantine was officially implemented in Sao Paulo, while elective medical appointments for adolescents with chronic disease were temporarily suspended. To mitigate the deleterious effect of the social isolation on physical and mental health among these patients, this study aims to test the effects of an online, home-based, exercise training program.
Single centre, open-label, single dose, parallel group study to investigate the PK, safety and tolerability of KY1005 after subcutaneous (s.c.) and intravenous (i.v.) administration, with i.v. KY1005 as a reference treatment.
New York City (NYC) has become the epicenter of the worldwide pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). By collecting and summarizing the experience with other major health care providers in the tristate (New York (NY), New Jersey (NJ) and Connecticut (CT)) are, the investigators are uniquely positioned to inform the rest of the country about what to expect and how to manage children and young adults with hematological, oncological or stem cell transplant diagnoses during the pandemic.
DESIGN Longitudinal prospective observational multicentre study. Primary objective: Understand the immune mechanisms driving COVID-19 disease in patients with a history of lung disease
There is considerable morbidity and mortality associated with cardiac surgery. Currently little effort is made to quantify how well the immune system of an individual can cope with inflammation or infection to which they are exposed during surgery. The investigators have previously demonstrated that having higher pre-operative antibody levels is associated with a lower risk of infection and a shorter stay in hospital after cardiac surgery. The investigators aim to study 150 patients undergoing aortic valve replacement and explore their dynamic immune responsiveness. The investigators will determine if this response is correlated with the post-operative outcome (development of post-operative infection or increased length of hospital stay). The investigators will compare this response with the previously measured static markers of immune competence and also with a novel device that may give a more rapid measure of dynamic immunity. The investigators will approach patients in the cardiac surgical pre-assessment clinic to see if they are willing to participate in the study. Immediately once under anaesthetic blood will be taken for testing and then again at the end of surgery, 24h after surgery, at discharge from hospital, and at follow-up clinic approximately 4 weeks later. There will be no additional needle insertions on top of those routinely performed. The investigators will collect data from the routine observations as far as 1 year after surgery. If the investigators can show an association between immune function and subsequent post-operative outcome it may be possible to determine ways to improve outcomes for patients undergoing heart surgery. This might include better information on risks and benefits of surgery, actively boosting immune function (vaccination, immune-nutrition), passively improving immunity (administering antibodies), or consider current alternatives to open heart surgery where the threat of infection or inflammation may be markedly reduced (eg trans-catheter aortic valve implantation)
SARS-CoV-2 outbreak causes a spectrum of clinical patterns that varies from asymptomatic infection to mildly symptomatic manifestations and more-severe forms that need intensive care. Until now, the immune response to SARS-CoV-2 virus infection has been poorly reported to help decision for immune modulation therapies. As a consequence, trials have been designed to test both anti-inflammatory molecules as steroids or anti-bodies against IL-6, and others proposing to "boost" immunity with interferon beta based on similar inclusion criteria. The immune response to infective agents including viruses may have a complex time evolution with early and late phases corresponding to different patterns, oscillating between pro-inflammation and immune-depression. The potential window to improve outcome in COVID-19 by therapeutic intervention aimed at a fine tuning between immune toxicity and immunodepression requires a longitudinal assessment during the course of illness, especially for the patients who develop acute respiratory failure. Immune monitoring of both innate and adaptive immunity would then be essential to appropriately design clinical trials. The whole blood cells evaluation was recorded according to the time intervals between the onset of symptoms and the sampling after ICU admission. Patients' care was standardized, especially with regard to ventilation, sedation, and antimicrobial treatment. In this study the investigators prospectively perform a longitudinal study of both innate and adaptive immunity on patients admitted to ICU for an COVID-19 related acute respiratory failure. The data will be analyzed in reference to the onset of initial symptoms and also to the admission in ICU. The primary end point is the evolution of the characterization of monocytes and their subsets in term of number and expression of HLA-DR. A similar approach is used for lymphocytes and their subtypes with in addition, an ex vivo testing of their capabilities to be stimulated by SARS-CoV-2 viral proteins in term of TNFalpha, INFgamma, and IL1beta production. The secondary end-point was to test the association with outcomes and other non-specific markers of inflammation as CRP (C reactive protein), PCT (procalcitonin), DDimers and ferritin.
This study is a Phase 1 / 2 trial to determine the safety and efficacy of CYNK-001, an immunotherapy containing Natural Killer (NK) cells derived from human placental CD34+ cells and culture-expanded, in patients with moderate COVID-19 disease.
