Our study aimed to evaluate asthma control over 56 weeks in patients treated with benralizumab in Swiss real-world settings.

Patients And Methods: Conducted across 13 centres, this prospective, observational, non-interventional study involved 73 adults with physician confirmed SEA.

Vaccination in adult patients with chronic lung diseases.

In Switzerland, additional vaccinations against influenza, COVID-19, Streptococcus pneumoniae and varicella zoster virus (VZV), are recommended for patients with chronic lung diseases such as COPD, asthma or interstitial lung disease, since infectious diseases often lead to exacerbation of lung diseases resulting in increased disease burden and mortality. In this review we give an overview on recommended vaccinations for patients with chronic lung diseases, also including vaccinations against pertussis and RSV, which are recommended in international guidelines. While continuous development of vaccines against S.

Microresonator photonic wire bond integration for Kerr-microcomb generation.

Extremely high-Q microresonators provide an attractive platform for a plethora of photonic applications including optical frequency combs, high-precision metrology, telecommunication, microwave generation, narrow linewidth lasers, and stable frequency references. Moreover, the desire for compactness and a low power threshold for nonlinear phenomena have spurred investigation into integrated and scalable solutions. Historically, crystalline microresonators with Q ∼ 10 were one of the first material platforms providing unprecedented optical performance in a small form factor.

Experimental Model of Cerebral Arterial Air Embolism in Conscious Rats.

In this work, an optimal air supply mode was selected to create a model of cerebral arterial air embolism (CAAE) on conscious male Sprague-Dawley rats (n=49). The efficacy of the selected model (administration of 100 μl/kg of air at a rate of 10 μl/min with an infusion pump) was determined by changes in serum biochemical parameters (cholesterol, alkaline phosphatase, inorganic phosphates, AST, and triglycerides), impaired motor functions in the Rotarod test, and visual assessment of the ischemic foci (staining of frontal sections with 1% triphenyltetrazolium chloride solution) at different terms after AAE. The model of AAE created by us confirmed impairment of coordination and motor function in conscious animals and reproduced the lethal consequences of this condition.

Modeling of Cerebral Ischemic Stroke in Conscious Rats via Arterial Air Embolization.

The etiological factor of cerebral ischemia in the vast majority of cases is vascular embolism. In the present study we investigated embolism caused by atmospheric air bubbles injected into the internal carotid artery of conscious rats. Immediately after embolism modeling, behavioral abnormalities were observed in the animals, and after 24 h, foci of brain damage were detected.

Effect of a helium and oxygen mixture on physiological parameters of rats with cerebral arterial air embolism.

Cerebral arterial air embolism (CAE) is a serious and potentially dangerous condition that can interrupt the blood supply to the brain and cause stroke. One of the promising gas mixtures for emergency treatment of air embolism is an oxygen-helium mixture. We modeled CAE in awake rats by injecting air into the common carotid artery.

[COPD : a still neglected condition].

Chronic obstructive pulmonary disease (COPD) is a heterogeneous lung disorder with a complex clinical picture. The diagnosis may be difficult at times, as COPD may develop insidiously and remain unnoticed for a long time. Therefore, general practitioners play a central role in early detection of disease.

[COPD - An Underestimated Disease].

COPD - An Underestimated Disease Chronic obstructive pulmonary disease (COPD) is a heterogeneous lung condition with a complex clinical picture. The diagnosis is not easy to make because COPD can develop insidiously and remain unnoticed for a long time. Therefore, general practitioners play a central role in the early detection of the disease.

Treatment of COVID-19 patients with a SARS-CoV-2-specific siRNA-peptide dendrimer formulation.

Background: Severe acute respiratory syndrome corona virus (SARS-CoV-2) infection frequently causes severe and prolonged disease but only few specific treatments are available. We aimed to investigate safety and efficacy of a SARS-CoV-2-specific siRNA-peptide dendrimer formulation MIR 19® (siR-7-EM/KK-46) targeting a conserved sequence in known SARS-CoV-2 variants for treatment of COVID-19.

Methods: We conducted an open-label, randomized, controlled multicenter phase II trial (NCT05184127) evaluating safety and efficacy of inhaled siR-7-EM/KK-46 (3.

Evaluation of the Efficiency of Oxygen-Helium Therapy for Patients with Covid-19-Associated Pneumonia.

This article summarizes the experience of managing patients with COVID-19-associated pneumonia treated in one of the intensive care units of a multidisciplinary hospital with and without a heated oxygen-helium mixture. It has been shown that the use of a heated oxygen-helium mixture in the complex therapy of pneumonia caused by SARS-CoV-2 is effective. A comparative analysis of the clinical manifestations of the disease and the results of laboratory tests in the main and control groups of patients confirm with a high degree of reliability the improvement of blood oxygenation, the normalization of the acid-base balance and the positive dynamics of the main parameters, which ultimately increases the efficacy and reduces the time of treatment.

CD25 as a unique marker on human basophils in stable-mildly symptomatic allergic asthma.

Background: Basophils in acute asthma exacerbation are activated as evidenced by their increased expression levels of activation markers such as CD203c and CD63. However, whether basophils of allergic asthmatics who are in stable phase and have no asthma exacerbations display a specific and distinctive phenotype from those of healthy individuals has yet to be well characterized.

Objective: We aimed to identify the phenotype of basophils from allergic asthmatics in the stable phase and investigate whether such a phenotype is affected by allergen stimulation.

A New Albomycin-Producing Strain of subsp. May Provide Protection for Ants .

There are several well-studied examples of protective symbiosis between insect host and symbiotic actinobacteria, producing antimicrobial metabolites to inhibit host pathogens. These mutualistic relationships are best described for some wasps and leaf-cutting ants, while a huge variety of insect species still remain poorly explored. For the first time, we isolated actinobacteria from the harvester ant and evaluated the isolates' potential as antimicrobial producers.

Properties Linked to the Selection of New Biotherapeutics.

Dysbiotic microbiota is often associated with health issues including inflammatory bowel disease or ulcerative colitis. In order to counterbalance host disorder caused by an alteration in the gut composition, numerous studies have focused on identifying new biotherapeutic products (NBPs). Among the promising NBPs is , a gut microbiota member part of the core microbiome that recently has received much attention due to the numerous beneficial properties it brings to its host.

Are blood cytokines reliable biomarkers of allergic disease diagnosis and treatment responses?

With the development of targeted therapies for allergic diseases, the need for biomarkers supporting disease diagnosis and management has increased. Recent research has elucidated the pattern of cytokines and their distinct roles in the pathogenesis of allergic diseases. This means that cytokines should be considered as biomarkers.

[Novelties in the Treatment of Asthma].

For general practitioners there have been important novelties in the treatment of asthma due to recent modifications of the international guidelines from Global Initiative for Asthma (GINA). In Step 1, use of short-acting beta2-agonists (SABA) without concomitant inhaled corticosteroids (ICS) as controller is no longer recommended for lack of efficacy and safety reasons. Instead, low dose ICS-formoterol as needed is recommended.
