tibiotics was high. Appropriate treatment of BSIs should be based on the current knowledge of bacterial resistance pattern. This study will help in formulating management of diagnostic guidelines and antibiotic policy.
Benralizumab can be utilized as add-on biological treatment of severe eosinophilic asthma. However, so far only a few real-life studies have been published with regard to the use of this anti-IL-5 receptor humanized monoclonal antibody.
The primary aim of this multicenter observational investigation has been to assess the therapeutic effects of benralizumab in patients with severe uncontrolled, corticosteroid refractory eosinophilic asthma. The secondary objective was to evaluate the efficacy of benralizumab with regard to positive or negative skin prick test (SPT).
Clinical, functional, and laboratory parameters were evaluated in order to verify the therapeutic actions of benralizumab in atopic and non atopic subjects with difficult-to-treat eosinophilic asthma. Moreover, a comparative evaluation was carried out in relation to the presence or absence of SPT positivity.
After 6 months of add-on biological therapy with benralizumab, our 111 patients experienced a marked improvement of their severe eosima, regardless of SPT positivity or negativity.
Taken together, the results of this real-world study indicate that in both allergic and non-allergic subjects benralizumab can be used as a valuable pharmacotherapeutic option for add-on biological therapy of severe eosinophilic asthma, regardless of SPT positivity or negativity.
Severe eosinophilic asthma (SEA) is characterized by high eosinophilia, severe symptoms, important comorbidities, frequent exacerbations, and poor asthma control. Benralizumab, targeting the interleukin-5 receptor alpha, proved effective in inducing rapid eosinophil depletion and amelioration of symptoms and lung function; it also allowed to reduce exacerbations and the use of oral corticosteroids (OCS). The present case series, spanning different subtypes of SEA, aimed at expanding the real-world experience with benralizumab in Italy.
We collected data from SEA patients treated with benralizumab, at baseline and during treatment. We focused on the effects of benralizumab in the following conditions and endpoints i) overlap between high-IgE and high-eosinophilic asthma; ii) presence of nasal polyposis as comorbidity; iii) corticosteroid-sparing effect; iv) patient perception.
Ten SEA patients (females N=7; age range 19-70 years) referred to 8 Italian Centers and treated with benralizumab were included, presenting with several comorbidities such as non-allergic disease (8/10), atopy (3/10), high IgE (5/10) and nasal polyposis (6/10). Overall, benralizumab yielded optimal disease control in all patients, particularly in terms of rapid clinical and functional improvement, decreased systemic steroid need (OCS therapy was completely discontinued in 7 cases) and amelioration of patient quality of life, except for 1 case, in whom other conditions not related to benralizumab therapy interfered with the patient perception.
Our findings further support the efficacy and safety of benralizumab observed in randomized clinical trials, providing even better results for lung function improvement.

Targeting cancer-associated fibroblast (CAF) is being explored as an approach to improve cancer therapies. The roles of CAF remain unclarified in malignant transformation of papillary thyroid cancer (PTC) into dedifferentiated thyroid cancer (DDTC). This study aimed to investigate correlations of CAF with dedifferentiation and clinicopathological characteristics of thyroid cancer.
We applied three different mRNA-based CAF gene signatures to quantify CAF in our cohort, the Gene Expression Omnibus (GEO) cohort and The Cancer Genome Atlas (TCGA) cohort, and analyzed expression of α-SMA by immunohistochemistry in thyroid cancer. The CAF score was analyzed for its associations with clinicopathological characteristics, genetic mutations, tumor-associated signaling pathways and immune landscape.
The CAF score increased significantly in DDTCs compared with normal thyroid tissues and PTCs, and the α-SMA-positive CAFs were found enriched in DDTCs. The high CAF score showed a significant correlation with the anaplastic phenotype in DDTC and low thyroid differentiation score in PTC. EIDD-1931 chemical structure Patients with a high CAF score remarkably increased the risk of aggressive outcomes in both DDTC and PTC. Furthermore, the CAF score was positively correlated with genetic mutations, oncogenic signaling pathways, the immune score and increased expression of tumor microenvironment (TME) target markers.
Our findings suggest CAFs positively correlate with dedifferentiation and aggressive outcomes of thyroid cancer, and targeting CAFs as a therapeutic approach may benefit DDTC patients.

KDM5C, a histone H3K4-specific demethylase, possess various biological functions in development of cancers. However, its relation to the microRNA (miRNA) regulation in lung cancer remains unknown. This study aims to study the regulatory role of KDM5C on modification of miR-133a in the progression of lung cancer.
Differentially expressed miRNAs were filtered from 34 paired lung cancer and paracancerous tissues. The correlation between miR-133a expression and the prognosis of lung cancer patients was determined by a bioinformatics website. Furthermore, malignant aggressiveness of lung cancer cells was detected after miR-133a upregulation by CCK-8, flow cytometry, and Transwell assays and in vivo tumorigenesis and metastasis experiments. Subsequently, we analyzed mRNA downregulated in cells overexpressing miR-133a using m microarray analysis and expounded the upstream regulatory mechanism of miR-133a using bioinformatics website prediction and functional validation.
miR-133a was reduced in lung cancer tissues, and patients with low expression of miR-133a have worse survival rates.
