The objective of the present study was to determine the use of systemic corti-costeroids (SCs) in patients with bronchial asthma using big data analysis.
We performed an observational, retrospective, ...noninterventional study based on secondary data captured from free text in the electronic health records. This study was per-formed based on data from the regional health service of Castille-La Mancha (SESCAM), Spain. We performed the analysis using big data and artificial intelligence via Savana® Manager version 3.0.
During the study period, 103 667 patients were diagnosed with and treated for asthma at different care levels. The search was restricted to patients aged 10 to 90 years (mean age, 43.5 95%CI, 43.4-43.7 years). Of these, 59.8% were women. SCs were taken for treatment of asthma by 58 745 patients at some point during the study period. These patients were older, with a higher prevalence of hypertension, dyslipidemia, diabetes, ob-esity, depression, and hiatus hernia. SCs are used frequently in the general population with asthma (31.4% in 2015 and 39.6% in 2019). SCs were prescribed mainly in primary care (59%), allergy (13%) and pulmonology (20%). The frequency of prescription of SCs had a direct impact on the main associated adverse effects.
In clinical practice, SCs are frequently prescribed to patients with asthma, especially in primary care. Use of SCs is associated with a greater number of adverse events. It is necessary to implement measures to reduce prescription of SCs to patients with asthma, especially in primary care.
Atypical fibroxanthoma and pleomorphic dermal sarcoma (PDS) are rare mesenchymal tumors. Due to the low incidence of PDS and a historically confusing nomenclature, little is known about the true ...aggressiveness of this tumor. The aim of this study was to investigate clinical and histologic risk factors for recurrence in PDS.
Retrospective, observational, bicentric study of 31 PDSs diagnosed and treated at Hospital Clínico Universitario de Valencia and Instituto Valenciano de Oncología in Valencia, Spain, between 2005 and 2020. We described the clinical and histologic features of these tumors and performed univariate analysis and multivariate Cox regression analysis.
In the univariate analysis, tumor recurrence (P<.001), necrosis (P=.020), lymphovascular invasion (P=.037), perineural invasion (P=.041), and mitotic count (<18 vs ≥18 mitoses per 10 high-power fields) (P=.093) were associated with worse disease-free survival. In the multivariate Cox regression analysis, mitotic count and lymphovascular invasion retained their significance as predictors of worse disease-free survival (P<.05).
PDS is an aggressive tumor in which a high mitotic count (≥18) and lymphovascular invasion are associated with a higher risk of recurrence and worse disease-free survival. Necrosis and perineural invasion are also probably linked to increased tumor aggressiveness.
NENs are a heterogeneous family of tumors of challenging diagnosis and clinical management. Their incidence and prevalence continue to rise across all sites, stages and grades. Although improved ...diagnostic techniques have led to earlier detection and stage migration, the improved prognosis documented over time for advanced gastrointestinal and pancreatic neuroendocrine tumors also reflect improvements in therapy. The aim of this guideline is to update practical recommendations for the diagnosis and treatment of gastroenteropancreatic and lung NENs. Diagnostic procedures, histological classification and therapeutic options are briefly discussed, including surgery, liver-directed therapy, peptide receptor radionuclide therapy, and systemic hormonal, cytotoxic or targeted therapy, and treatment algorithms are provided.
