Filter by:Biodiversity is essential for nature and human well-being. Land use has reduced biodiversity in cities that is associated with altered commensal microbiota and a rising burden of immunological disorders among urban children. The investigators will estimate how rewilding of kindergarten yards affects commensal microbiome, prevalence of allergies, asthma, atopic dermatitis and infections, cortisol levels, cognitive skills and plasma cytokine levels of children. Our specific aims are: To assess if rewilding diversifies health-associated skin, saliva and gut microbiota and reduces infectious diseases and atopic or allergic symptoms. Assess whether the rewilding has positive effects on cognitive skills. Assess whether the rewilding changes cortisol and plasma cytokine levels. The investigators will recruit altogether 320 (160 per treatment) study subjects aged between 1-5 to questionnaire study (Task 2), from which 120 study subjects will be analyzed more detailed using microbiological and blood samples (Task 1).
The application of HFNC therapy in patients with airway stent, improving both humidification and clearance of the airway secretion, could potentially reduce the risk of mucoid impaction, respiratory infections and granulation. HFNC therapy could be superior to nebulization of normal saline (usual care) in order to keep the stent cleaned, reducing, by inference, the risk of complications, as defined above.
Does the use of the BIOFIRE® FILMARRAY® Pneumonia Panel plus in hospitalized patients with lower respiratory infections lead to a reduction in length of hospital stay (LOS) and customized antibiotic treatment (higher amount of specific vs empiric treatment, shorter treatment duration, less antibiotic treatment, lower incidence of side effects) compared to the standard of care?
The last decade has seen a significant increase in secondary Aspergillus infections, not only due to primary hypersensitivity, and immunodeficiency based on oncological diseases and their therapy, but mainly due to a rise in severe respiratory infections (H1N1, COVID-19, bacterial infections). This is most evident in critically ill patients whose life is threatened by invasive pulmonary aspergillosis (IPA), with over 90 % of cases being caused by Aspergillus fumigatus. In recent decades, various biomarkers with well-known limits of use (Aspergillus DNA, galactomannan, 1,3-ß-D-glucan) have been used for early diagnosis of IPA. However, the clinical need to clearly distinguish the onset of IPA from colonization is much more significant. The current biomarkers only provide "probable IPA" interpretation, and the diagnosis is rarely confirmed. Based on our preliminary studies, the use of new low molecular weight substances (secondary metabolites) combined with acute-phase proteins (pentraxin 3) allows very reliable immediate confirmation of IPA. In tissue samples, bronchoalveolar lavage fluid, endotracheal aspirate, breath condensate, serum, and urine of critically ill patients, the investigators will be able to recognize and confirm IPA in time using highly sensitive mass spectrometry detecting specific microbial siderophores in correlation with a significantly increased concentration of acute-phase host protein (pentraxin 3) within hours of the beginning of the invasion of lung tissue. Through a prospective multicentre study, the investigators will evaluate the benefit of new biomarkers in non-invasive IPA confirmation, improve the IPA diagnostic algorithm and transfer the detection method to MALDI-TOF spectrometers widely used in Clinical laboratories in the Czech Republic. In MALDI-TOF mass spectrometry, the ion source is matrix-assisted laser desorption/ionization (MALDI), and the mass analyser is a time-of-flight (TOF) analyser. The study results will contribute to a high clarity of IPA cases, the accurate introduction of antifungal therapy, and a better prognosis of survival of critically ill patients.
The main objectives of the trial are to assess the efficacy and safety of trimodulin as adjunctive treatment to standard of care (SoC) compared to placebo plus SoC in adult hospitalized subjects with non-severe community-acquired pneumonia (CAP) or moderate / severe Coronavirus Disease 2019 (COVID-19) pneumonia. Other objectives are to determine pharmacokinetic (PK) and pharmacodynamic (PD) properties of trimodulin.
COVID-19 is an infectious disease which presents a heterogenous clinical presentation. Recent investigations suggest that people who were infected by COVID-19 often develop physical disabilities (i.e. pain, fatigue), neurological complications and and mainly disorders of the respiratory system, such as respiratory muscle weakness after hospital discharge. Many therapeutic approaches such as transcranial direct current stimulation (tDCS) have been proposed to minimize functional and structural impairments. The aim of the present study is to evaluate the effects of inspiratory muscle training associated with stimulation of the diaphragmatic motor cortex through hd-tdcs in post-COVID-19 patients on inspiratory muscle strength, pulmonary function, inflammatory levels and functional capacity.

Recent investigations suggest that people who were infected by COVID-19 often develop physical disabilities (i.e. pain, fatigue) and neurological complications after hospital discharge. Many therapeutic approaches such as transcranial direct current stimulation (tDCS) have been proposed to minimize functional and structural impairments. Electroencephalogram (EEG) has been used in this population to assess electrophysiological changes in the brain. However, evidences about EEG utilization as efficacy predictor of tDCS in COVID-19 people rest inconclusive.Our objective is to evaluate EEG as neurobiological predictor marker of tDCS efficacy on fatigue, pain, quality of life, self-efficacy and functional capacity in the chronic phase of COVID-19.
A Phase 2a, randomized, double-blind, placebo-controlled, multiple ascending dose study in patients who are hospitalized with presumed pneumonia requiring supplemental oxygen therapy. The purpose of this study is to examine the safety, tolerability and efficacy of AV-001 Injection administration daily to the earlier of day 28 or EOT (day prior to hospital discharge). A total of 120 eligible patients (20 patients in each of cohort 1, 2 and 3 and 60 patients in cohort 4) will be recruited from up to 25 participating institutions/hospitals. Patients will be randomized in a 1:1 ratio to receive either AV-001 Injection or AV-001 placebo Injection, together with standard of care (SOC).
The aim of this study is to evaluate the efficacy of an optimal-massive intervention (OMI) based on increasing shear viscosity of fluids, nutritional support with oral nutritional supplements (ONS) and triple adaptation of food (rheological and textural, caloric and protein and organoleptic) and oral hygiene improvement on the incidence of respiratory infections in older patients with OD. We have designed a randomized clinical trial, with two parallel arms and 6 months follow-up. The study population will be constituted by older patients of 70 years or more with OD hospitalized at Hospital de Mataró by an acute process that will be identified by using the volume-viscosity swallow clinical test. We will consecutively recruit 500 subjects during admission (Geriatrics, Internal medicine, etc.) at the Hospital de Mataró. Patients included will be randomly assigned to one of both interventional groups: a) study intervention: multifactorial intervention based on fluid viscosity adaptation (with a xanthan gum thickener -> Nutilis Clear®), nutritional support with a triple adaptation of food (texture, caloric and protein content, organoleptic) + pre-thickened ONS and evaluation and treatment of oral hygiene (tooth brushing + antiseptic mouthwashes + professional dental cleaning), or b) control intervention: standard clinical practice (fluid adaptation with Nutilis Powder and simple texture adaptation for solids). Main outcome measures: respiratory infection incidence during the 6-month period follow-up. Secondary outcomes: mortality at 6 months, general hospital readmissions and readmissions due to respiratory infections, nutritional status, hydration status, quality of life, functional status, oral hygiene and dysphagia severity and its relationship with other study variables.
Rationale: Fluid overload is a common complication in children who are admitted to the pediatric intensive care for mechanical ventilation. Acute lung infection is a frequent cause for admission to the PICU and forms an uniform group with a single organ failure. In these critically ill children, fluid overload is associated with adverse outcome. Restricting the volume of fluids already in an early stage of ICU admission may prevent fluid overload during mechanical ventilation and thus improve clinical outcome. However, at the same time fluid restriction may interfere with appropriate energy and macronutrient intake that is needed for recovery. Objective: The main goal of this pilot study is to evaluate the feasibility of a restrictive fluid management protocol and investigate its effect on the occurrence of fluid overload in mechanically ventilated children with acute infectious lung disease. Study design: Single-center prospective randomized feasibility and pilot study in preparation of a multi-center randomized controlled trial (RCT). Study population: Mechanically ventilated children with (suspicion of) acute infectious lung disease admitted to the pediatric intensive care unit (PICU) of the Emma Children's Hospital, Academic Medical Center, Amsterdam. Intervention: Patients receive either liberal (control group) or a restrictive (experimental group) fluid treatment, while ensuring appropriate caloric intake. Main study parameters/endpoints: Primary outcomes are cumulative fluid balance and body weight during the first week of mechanical ventilation. Secondary outcomes (in preparation of the larger multi-center RCT) include: mortality, duration of mechanical ventilation and oxygenation indices. To determine the feasibility, in- and exclusion rate, adherence to treatment arms, need for fluid bolus, need for diuretics and hemodynamic indices as well as energy and protein intake are studied. Both fluid management protocols reflect a variant of current clinical practice, hence will not provide extra burden or risk to patients included in the study. Patients will be randomized to either of the fluid protocol arms on admission to the PICU (at start of mechanical ventilation). Patients included in the restrictive fluid treatment arm might have direct benefit from the study if indeed fluid overload is less common in this group.
