Filter by:The increasing number of persons >65 years of age form a special population at risk for nosocomial and other health care-associated infections. The vulnerability of this age group is related to impaired host defenses such as diminished cell-mediated immunity. Lifestyle considerations, e.g., travel and living arrangements, and residence in nursing homes, can further complicate the clinical picture. The magnitude and diversity of health care-associated infections in the aging population are generating new arenas for prevention and control efforts. Common infections leading to hospitalizations in this age group result in respiratory infections and bacteraemia and the impact of these infections on the quality of life and disability in aged populations has not been accurately quantified in a European setting. This study aims to capture and quantify the impact of infectious diseases on quality of life in an aged population.
Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the most frequent complications of the COVID-19 pandemic. In these conditions, hypoxemia may result from : i) a pulmonary vascular dilatation resulting from an impaired hypoxic pulmonary vasoconstriction and leading to ventilation-perfusion mismatching within the lungs and ii) thrombosis-mediated perfusion defects. Pulmonary vascular dilation might be due to a relative failure of the physiological acute hypoxic pulmonary vasoconstriction, in the context of an over-activation of a regional vasodilatation cascade, as part of a dysfunctional inflammatory process. Perfusion abnormalities associated with pulmonary vascular dilation are suggestive of intrapulmonary shunting toward areas where gas exchange is impaired, ultimately leading to a worsening ventilation-perfusion mismatch, a regional hypoxia and a profound hypoxemia. Increased plasma levels of VEGF have been reported in moderate to severe COVID-19 pneumonia, highlighting the role of VEGF in the pathophysiology of the disease. A better prognosis has been reported in critically ill patients with lower levels of growth factors, HGF and VEGF-A at the time of ICU admission. Recent data of the study NCT 04275414 by Pang J et al have suggested that patients receiving a single-dose of bevacizumab have improved their oxygen support status in 92% of cases during a 28-day follow-up period, as compared with 62% of cases in an external cohort receiving standard care. Correcting endothelial permeability and vasodilatation with VEGF-targeted therapy could allow repair damaged vascular endothelium, have an indirect anti-inflammatory effect (limiting alveolar exudation of circulating inflammatory and procoagulant mediators) and improve oxygenation and therefore reduce the proportion of patients with severe forms requiring ICU referral and finally patient death. This clinical trial will therefore focus on the specific efficacy of bevacizumab in COVID-19 patients with severe hypoxemia.
This is a randomized study that sought to analyze the diagnostic accuracy of the telemedicine consultation of patients suspected of respiratory tract infections during COVID-19 pandemic in comparison with the face-to-face evaluation at the emergency department.
The medical charts of all COVID-19 cases (n=1200) from 17 long-term care facilities in Montreal, Canada will be reviewed, to compare patients who survived to patients who did not survive. Through multilevel logistic regression, the risk of death will be estimated for institutional predictors of mortality, while controlling for individual risk factors. Individual covariates include clinical features (age, sex, Charlston comorbidity index, SMAF autonomy score, severity criteria) and medical treatments (IV fluids, anticoagulation, oxygen, regular opiates, corticosteroids). Aggregate covariates include epidemiological data (attack rates, timing of outbreak) and institutional characteristics (number of beds, air exchange per hour, presence of a dedicated COVID-19 unit at the time of outbreak, staff compliance to infection control measures, staff infection rates, understaffing, proportion of semi-private rooms, proportion of wandering wards and other special units).
This study is a randomized controlled trial where participants are randomly assigned in a 1:1 ratio to either a rapid test group or a control group. Standard care is provided in the control group. Follow-up is conducted until discharge from the hospital, followed by telephone check-ins and completion of questionnaires by the participants themselves or their proxies until 30 days after randomization. Children of any age presenting at selected participating sites with acute respiratory tract infections, where initial treatment decisions are uncertain, are eligible to participate. The study aims to enrol 520 participants and involves Paediatric Emergency Rooms across Europe.
Psychosocial and lifestyle factors in Army recruits likely contribute to increased susceptibility to infection and injury during basic Army training. The primary aim of this study is to assess the influence of psychosocial and lifestyle factors at the start of basic Army training on immune health (e.g. respiratory infection and antibody response to influenza vaccination) and injury during training, in an observational design. A secondary aim is to establish whether changes in psychosocial and lifestyle factors during training impact immune health (e.g. response to hepatitis B vaccination). Using an interventional design, participants will be randomly allocated into two experimental groups: (i) Routine vaccination group: to receive first hepatitis B vaccination at initial medical assessment upon entry to basic training and second hepatitis B vaccination 1 month later; (ii) Delayed vaccination group: to receive first hepatitis B vaccination during week 5 of training and second hepatitis B vaccination 1 month later.
to assess the efficacy and safety of a standardized Withania somnifera extract (Sensoril®) as an immunomodulator in individuals suffering from recurrent URTIs. The study population will be administered with this unique blend of WS extract for 12 weeks and will be assessed as per the study designated efficacy and safety variables.
This is a randomized, double-blind, placebo-controlled study to evaluate the impact of bovine Lactoferrin (bLf) on respiratory tract infections (RTIs) in an elderly population in the United States.
This is a prospective cohort study that describes focused lung ultrasound (FLUS) findings in patients presenting with symptoms of an acute lower respiratory tract infection (LRTI) in general practice in Denmark. Ten general practitioners (GPs) will perform FLUS in addition to their usual care of adults presenting with symptoms of an acute LRTI where the GP suspects a community-acquired pneumonia (CAP). Eligible patients will consecutively be invited to participate during a two months' study period until each GP has included a total of ten patients. The GPs will register information about patients including age, gender, symptoms, clinical findings, results of any point-of-care test performed, if antibiotic treatment was prescribed and they will register information on FLUS performance and findings.
Patients who are critically ill in intensive care with moderate to severe acute respiratory infection often require mechanical ventilation. Prolonged ventilation increases the risk of lung damage and other side effects as a result of long term use of sedation medications. Extracorporeal membrane oxygenation therapy (ECMO), is a relatively new technology that uses a pump to remove blood from the body and return it back to the body after adding oxygen and removing carbon dioxide. ECMO can be used on patients who require mechanical ventilation and can function without the need for ongoing mechanical ventilation, thus reducing risk of side effects. Participants will be randomised into either the early ECMO therapy group or will continue standard treatment involving mechanical ventilation. This pilot study aims to determine if a phase 3 Randomised Control Trial (RCT) is feasible for the use of early ECMO therapy to treat patients with Severe Acute Respiratory Infection (SARI). The success of the study will be determined by the successful recruitment of adult patients, that there is a difference between ECMO utilisation between groups and that there are no safety issues.
