Evolution of adolescents' dietary patterns in Northeast Brazil from 2008 to 2018.

Objective: To evaluate the evolution of the dietary patterns of adolescents in the northeast region of Brazil.

Methods: Secondary analysis of data from the Pesquisa de Orçamentos Familiares (POF - Household Budget Surveys), collected by the Brazilian Institute of Geography and Statistics (IBGE) in the years 2008-2009 and 2017-2018. A total of 3,095 adolescents were evaluated in 2008-2009 and 3,015 in 2017-2018.

Optical coherence tomography angiography characteristics of the retinal and optic disc morphology in prolactinoma.

Purpose: To investigate changes in the retinal and optic disc (OD) morphology in prolactinoma patients without optical chiasmal compression and/or visual field defects using optical coherence tomography angiography (OCTA).

Methods: In this cross-sectional imaging study, 16 consecutive prolactinoma patients (group 1, 32 eyes) and 15 age- and gender-matched healthy subjects (group 2, 30 eyes) underwent a thorough neuro-ophthalmological examination, which included testing for the presence of any intracranial compressive lesion that could cause optic neuropathy. Retinal morphological parameters, outer retinal and choriocapillaris flow areas, as well as OD vessel density (VD) and retinal nerve fiber layer (RNFL) thickness in for quadrants were then measured using OCTA.

Relationship between vitamin D in obstructive sleep apnea syndrome and psoriasis patients.

Introduction: Although psoriasis and obstructive sleep apnea syndrome (OSAS) are associated with systemic inflammation, studies on their potential bilateral relationship are not sufficient.

Aim: To investigate vitamin D levels and receptor gene polymorphisms in patients with OSAS and psoriasis and the associations with these diseases.

Material And Methods: One hundred thirty-seven patients included in the study consisted of 4 different groups: group 1, those with both diseases; group 2, those with OSAS only; group 3, patients with psoriasis only; and group 4, healthy controls.

The Diagnostic Utility of Flow Cytometry in Celiac Disease Presented Isolated Iron Deficiency Anemia.

Background: Flow cytometric analysis of intestinal intraepithelial lymphocytes contributes to the diagnosis of celiac disease. Celiac disease may present with iron deficiency anemia alone which is considered as one of the forms of atypical celiac disease. In this study, we have aimed to investigate the diagnostic utility of flow cytometric analysis of intraepithelial lymphocytes in this atypical form.

The role of oxidized phospholipids in COVID-19-associated hypercoagulopathy.

Objective: There is more pronounced hypercoagulation in COVID-19 infection than in other viral lung infections. Oxidized phospholipids (OxPLs) appear in COVID-19-infected lungs due to oxidative stress, after which they promote the induction of tissue factor (TF) expression and inflammatory programmers in monocytes, as well as activate endothelial cells to recruit and bind to monocytes. Therefore, we aimed to demonstrate the role of OxPLs in inflammatory and procoagulant responses in COVID-19 infection.
