Expressed sequence tags (ESTs) represent 500-1000-bp-long sequences corresponding to mRNAs derived from different sources (cell lines, tissues, etc.). The human EST database contains over 8,000,000 sequences, with over 4,000,000,000 total nucleotides. RNA molecules are transcribed from a genomic DNA template; therefore, all ESTs should match corresponding genomes. Nevertheless, we have found in the human EST database approximately 11,000 ESTs not matching sequences in the human genome database. The presence of "trash" ESTs (TESTs) in the EST database could result from DNA or RNA contamination of the laboratory equipment, tissues, or cell lines. TESTs could also represent sequences from unidentified human genes or from species inhabiting the human body. Here, we attempt to identify the sources of human EST database contaminations. In particular, we discuss systematic contamination of the mammalian EST databases with sequences of plants.

Purpose: To measure the impact of national regulatory actions implemented in France in August 2018 and June 2019 to reduce the risk of meningioma associated with the use of cyproterone acetate (CPA).
Methods: Using the French National Healthcare database, we calculated the monthly number of CPA users among cisgender women, men and transgender women in 2010-2021, the monthly proportion of users with cerebral imaging screening, and the annual rate of meningioma surgery associated with CPA use. CPA discontinuations and switches were analysed.

Objectives: To evaluate (1) the association between nailfold capillaroscopy pattern and 5-year risk for incident interstitial lung disease and (2) the association between transition in nailfold capillaroscopy pattern and risk of incident interstitial lung disease.
Methods: Data of adult patients from the EUSTAR database fulfilling the ACR-EULAR criteria with a disease duration ⩽5 years, having a scleroderma pattern at nailfold capillaroscopy with high-resolution computed tomography confirmed absence of interstitial lung disease (i.e.
Reintervention for Acute Aortic Prosthesis Endocarditis: Early and Mid-Term Outcomes.

This study aimed to analyze the outcomes and challenges associated with surgical redo procedures following aortic valve replacement for acute infective endocarditis. While transcatheter aortic valve implantation is growing in terms of its utilization for degenerative bioprostheses failure, valve-in-valve procedures are limited in acute aortic endocarditis. Surgical interventions for aortic prosthesis endocarditis carry a significant risk, with a higher mortality and morbidity, often requiring concomitant complex procedures.

Background: Epidermal necrolysis (EN) is a rare and severe condition, characterized by a diffuse skin and mucosal detachment and mainly induced by drugs. Literature is scarce regarding the rate of recurrences and culprit drug re-exposure.
Objectives: To assess the rate of EN recurrences as well as high notoriety drugs re-exposures in patients with EN.
