Mast Cells in Allergic and Non-Allergic Upper Airways Diseases: Sentinel in the Watchtower.

Mast cells are immune system cells with the most disparate functions, but are also among the least understood. Mast cells are implicated in several known pathological processes, tissue homeostasis, and wound repair. However, they owe their notoriety to allergic diseases, of which they represent the effector cell par excellence.

Lung function trajectories in common variable immunodeficiencies: An observational retrospective multicenter study.

Background: Respiratory disease is a frequent cause of morbidity and mortality in common variable immunodeficiencies (CVIDs); however, lung function trajectories are poorly understood.

Objective: We sought to determine lung physiology measurements in CVIDs, their temporal trajectory, and their association with clinical and immunologic parameters.

Methods: This retrospective study from 5 Italian centers included patients with CVIDs who had longitudinal pulmonary function tests (PFTs) and chest computed tomography scan available.

Stop antibiotics when you feel better? Opportunities, challenges and research directions.

Shortening standard antibiotic courses and stopping antibiotics when patients feel better are two ways to reduce exposure to antibiotics in the community, and decrease the risks of antimicrobial resistance and antibiotic side effects. While evidence shows that shorter antibiotic treatments are non-inferior to longer ones for infections that benefit from antibiotics, shorter courses still represent average treatment durations that might be suboptimal for some. In contrast, stopping antibiotics based on improvement or resolution of symptoms might help personalize antibiotic treatment to individual patients and help reduce unnecessary exposure.

Drivers of epidemic dynamics in real time from daily digital COVID-19 measurements.

Understanding the drivers of respiratory pathogen spread is challenging, particularly in a timely manner during an ongoing epidemic. In this work, we present insights that we obtained using daily data from the National Health Service COVID-19 app for England and Wales and that we shared with health authorities in almost real time. Our indicator of the reproduction number () was available days earlier than other estimates, with an innovative capability to decompose () into contact rates and probabilities of infection.

The Effect of Exposure to SARS-CoV-2 Vaccination and Infection on Humoral and Cellular Immunity in a Cohort of Patients with Immune-Mediated Diseases: A Pilot Study.

Immunization against COVID-19 is needed in patients with immune-mediated inflammatory diseases (IMIDs). However, data on long-term immunity kinetics remain scarce. This study aimed to compare the humoral and cellular response to COVID-19 in patients with immune-mediated inflammatory diseases (IMIDs) compared to healthy controls.

State of the art: the treatment of systemic lupus erythematosus.

Purpose Of Review: Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with dysregulated cells in the immune system. The disease affects organs like kidneys, nervous system, joints, and skin. To manage SLE effectively, novel treatments targeting immune system components have been developed.

COVID-19 Clinical Features and Outcome in Italian Patients Treated with Biological Drugs Targeting Type 2 Inflammation.

This is a multicentric investigation involving two Italian centers that examined the clinical course of COVID-19 in patients receiving biological therapy targeting type 2 inflammation and those not receiving biologicals. Since the beginning of the COVID-19 pandemic, the management of respiratory and allergic disorders and the potential impact of biological therapy in the most severe forms has been a point of uncertainty. Our multicentric investigation aimed to compare the clinical course of COVID-19 and the impact of vaccination in an Italian cohort of patients with atopic disorders caused by a type 2 inflammation, such as eosinophilic asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), atopic dermatitis (AD), and chronic spontaneous urticaria (CSU).

Periostial and cartilage morphology in knee osteoarthritis: beneficial effects of supplementation with Pycnogenol® + Centellicum®.

Background: The aim of this registry study was to evaluate the progress of osteoarthrosis (OA) symptoms after the intake of a new standardized supplement combination (Pycnogenol + Centellicum, both Horphag Research) in a group of subjects with OA.

Methods: Supplemented subjects took daily 150 mg Pycnogenol + 450 mg Centellicum for 6 months. Another comparable group of subjects using only standard management (SM) was included as a reference.

Pycnogenol® improves cognitive function in post-stroke patients: a 6 month-study.

Background: This pilot study in post-stroke patients evaluated the effects of supplementation with Pycnogenol on alterations in cognitive functions (COFU) over a period of 6 months, starting 4 weeks after the stroke.

Methods: The effects of supplementation - possibly acting on residual brain edema, on global cognitive function, attention and on mental performance - were studied. A control group used standard management (SM) and the other group added Pycnogenol, 150 mg daily to SM.

Degradation of atrazine, glyphosate, and 2,4-D in soils collected from two contrasting crop rotations in Southwest Chaco, Argentina.

Argentina stands as one of the leading consumers of herbicides. In a laboratory incubation experiment, the persistence and production of degradation metabolites of Atrazine, 2,4-D, and Glyphosate were investigated in a loamy clay soil under two contrasting agricultural practices: continuous soybean cultivation (T1) and intensified rotations with grasses and legumes (T2). The soils were collected from a long-term no-till trial replicating the influence of the meteorological conditions in the productive region.

Prevention and control of jet lag symptoms and temporary impairment of cognitive function with Pycnogenol® in healthy individuals and in hypertensives.

Background: The aim of this registry study was to evaluate the efficacy of Pycnogenol in controlling signs/symptoms and temporary impairment of cognitive function (COFU) associated with jet lag. Previous flight studies have shown a decrease in the level of jet lag symptoms with Pycnogenol. The control of jet lag signs/symptoms appeared to be correlated with flight-related microangiopathy and peripheral edema.

Impact of Exposure to Vaccination and Infection on Cellular and Antibody Response to SARS-CoV-2 in CVID Patients Through COVID-19 Pandemic.

Purpose: The purpose of this study is to investigate the kinetics of response against SARS-CoV-2 elicited by vaccination and/or breakthrough infection (occurred after 3 doses of BNT162b2) in a cohort CVID patients.

Methods: We measured humoral and cellular immunity using quantitative anti-spike antibody (anti-S-IgG) and neutralization assay and specific interferon-gamma release assay (IGRA) before and after the third or fourth dose of BNT162b2 and/or after COVID-19.

Results: In CVID, 58.

Predictors of unsustained measurable residual disease negativity in patients with multiple myeloma.

The prognostic impact of achieving and in particular maintaining measurable residual disease (MRD) negativity in multiple myeloma is now established; therefore, identifying among MRD-negative patients the ones at higher risk of losing MRD negativity is of importance. We analyzed predictors of unsustained MRD negativity in patients enrolled in the FORTE trial (NCT02203643). MRD was performed by multiparameter flow cytometry (sensitivity of 10-5) at premaintenance and every 6 months thereafter.

Intestinal fat absorption shifting by polyglucosamine biopolymer: control of lipids and reduction of progression of early subclinical atherosclerosis.

Background: Atherosclerosis progression is possible in subjects with limited alteration of body weight, lipid profile, and oxidative stress. The ultrasound carotid thickness (IMT) and arterial wall modification (granulation and bubbles) are evident signs of the disease. Intestinal fats absorption shifting (IFAS) is expected to prevent or reduce the arterial damage.

Eosinophil Cationic Protein Variation in Patients with Asthma and CRSwNP Treated with Dupilumab.

Background: Asthma is a clinical syndrome characterized by recurrent episodes of airway obstruction, bronchial hyperresponsiveness and airway inflammation. Most patients with asthma present a "type 2" (TH2) inflammation. ILC2 and TH2 cells release cytokines IL4, IL-13 and IL-5.

This study aimed to test possible metabolic differences between ewes and goats in response to an intravenous glucose infusion. Thirty-six animals, 18 mature Sarda dairy ewes and 18 mature Saanen goats (from 15 to 150 ± 11 d in milk [DIM], mean ± SD; body weight: 49.8 ± 6.

Giant cell arteritis and innovative treatments.

Purpose Of Review: Giant cell arteritis (GCA) is an idiopathic and persistent condition characterized by granulomatous vasculitis of the medium and large vessels with overlapping phenotypes, including conventional cranial arteritis and extra-cranial GCA, also known as large-vessel GCA. Vascular problems linked with large vessel involvement may partly be caused by delayed diagnosis, emphasizing the necessity of early detection and the fast beginning of appropriate therapy. Glucocorticoids are the cornerstone of treatment for GCA, but using them for an extended period has numerous, often severe, side effects.

Intestinal fat absorption shifting: polyglucosamine biopolymer controls lipids and weight and reduces the progression of subclinical atherosclerosis.

Background: Intestinal fat absorption shifting (IFAS) can be obtained in hyperlipidemic subjects with polyglucosamine biopolymer (BP) able to segregate most metabolic fats in the gut, making them unavailable for intestinal interaction (shift). The aim of this study was to evaluate the effects of a SM (standard management) for hyperlipidemia in asymptomatic subjects for primary cardiovascular prevention focusing on arterial wall morphology (IMT thickness) in comparison to SM associated to the administration of the BP.

Methods: Two groups of comparable subjects (SM and SM+oral BP, 3 g/day) were considered; subjects were managed - in a supplement, pilot registry - for a year.
