Applicability of the International Cytopathology Reporting System of Serous Fluids in a Brazilian City.

Introduction: The International Academy of Cytology and the American Society of Cytopathology developed the International System of Serous Fluid Cytopathology (TIS) to standardize cytological reports. Effusions in pleural, peritoneal, and pericardial cavities are valuable sources of information for medical diagnosis, especially in oncological scenarios. The TIS classification is divided into five categories: non-diagnostic (ND), negative for malignancy (NFM), atypia of uncertain significance (AUS), suspected malignancy (SFM), and malignant (MAL).

Effect of the COVID-19 pandemic on surgery for indeterminate thyroid nodules (THYCOVID): a retrospective, international, multicentre, cross-sectional study.

Background: Since its outbreak in early 2020, the COVID-19 pandemic has diverted resources from non-urgent and elective procedures, leading to diagnosis and treatment delays, with an increased number of neoplasms at advanced stages worldwide. The aims of this study were to quantify the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic; and to evaluate whether delays in surgery led to an increased occurrence of aggressive tumours.

Methods: In this retrospective, international, cross-sectional study, centres were invited to participate in June 22, 2022; each centre joining the study was asked to provide data from medical records on all surgical thyroidectomies consecutively performed from Jan 1, 2019, to Dec 31, 2021.

Cervical cytology results among pregnant and non-pregnant women in Brazil.

Objective: To compare the prevalence of abnormal cervical smear results among pregnant and non-pregnant women with and without representation of the transformation zone (TZ) in a mid-sized city in Brazil.

Study Design: This observational analytical and retrospective study analyzed cervical smear results from pregnant and non-pregnant women in a mid-sized city in Brazil. Private data were collected at private clinics over seven years and from public services over 16 years.
