Background: In August 2017, the European Commission awarded the "European Study on Clinical Diagnostic Reference levels for X-ray Medical Imaging" project to the European Society of Radiology, to provide up-to-date Diagnostic Reference Levels based on clinical indications. The aim of this work was to conduct an extensive literature review by analysing the most recent studies published and the data provided by the National Competent Authorities, to understand the current situation regarding Diagnostic Reference Levels based on clinical indications for computed tomography.
Results: The literature review has identified 23 papers with Diagnostic Reference Levels based on clinical indications for computed tomography from 15 countries; 12 of them from Europe. A total of 28 clinical indications for 6 anatomical areas (head, cervical spine/neck, chest, abdomen, abdomen-pelvis, chest-abdomen-pelvis) have been identified.
Conclusions: In all the six anatomical areas for which Diagnostic Reference Levels based on clinical indications were found, a huge variation of computed tomography dose descriptor values was identified, providing evidence for a need to develop strategies to standardise and optimise computed tomography protocols.

Diagnostic Accuracy of Rapid Antigen Tests for Trichomoniasis: A Meta-analysis.
J Low Genit Tract Dis

Department of Pathology, Saint Paul's Hospital, Taoyuan, Taiwan.
Objective: Trichomoniasis is a globally prevalent sexually transmitted infection caused by the protozoan Trichomonas vaginalis. Polymerase chain reaction (PCR) is the gold standard for diagnosing trichomoniasis, but it is expensive. Antigen tests are immunochromatographic immunoassays that detect T.

Diagnosing cardiac amyloidosis (CA) is challenging because of its phenotypic heterogeneity, multiorgan involvement requiring interaction among experts in different specialties and subspecialties, lack of a single noninvasive diagnostic tool, and still limited awareness in the medical community. Missing or delaying the diagnosis of CA may profoundly impact on patients' outcomes, as potentially life-saving treatments may be omitted or delayed. The suspicion of CA should arise when "red flags" for this condition are present, together with increased left ventricular wall thickness.

Department of Clinical Epidemiology and Center for Population Medicine, Aarhus University Hospital and Aarhus University, Aarhus, Denmark.
Background: Severe infection is the most frequent disease underlying disseminated intravascular coagulation (DIC). To improve understanding of the clinical course, we examined the association between infection type and short-term mortality in patients with infection-associated DIC.
Methods: Patients with infection-associated DIC registered in the Danish Disseminated Intravascular Coagulation (DANDIC) cohort were categorised by infection type: pulmonary, intra-abdominal, urogenital, others, multiple infection sites and unknown foci.
New spirometry recommendations from the Brazilian Thoracic Association - 2024 update.
J Bras Pneumol
January 2025
. Laboratório de Função Pulmonar, Instituto de Assistência ao Servidor Público Estadual de São Paulo Francisco Morato Pereira - IAMSPE-FMO - São Paulo (SP), Brasil.
The latest pulmonary function guideline from the Brazilian Thoracic Association was published in 2002, since which there have been updates to international guidelines (mainly those from the European Respiratory Society and the American Thoracic Society), as well as new national and international publications on various aspects of the performance, interpretation, and clinical implications of spirometry. Despite those updates, a careful analysis of what applies to the reality in Brazil is essential, because there have been studies that evaluated individuals who are representative of our population and who could show responses different from those of individuals in other regions of the world. This document is the result of the work of a group of specialists in pulmonary function who evaluated relevant scientific articles that could be applicable to the population of Brazil.

Background: ST-segment elevation myocardial infarction (STEMI) is a common and severe form of acute myocardial infarction (AMI).
Objectives: The study aimed to investigate the relationship between serum nitric oxide (NO) and endothelin-1 (ET-1) levels with the severity of STEMI and their predictive value for major adverse cardiovascular events (MACE) within one year after percutaneous coronary intervention (PCI) in STEMI patients.
Methods: The retrospective study was conducted on 269 STEMI patients who underwent PCI.
