Hematological parameters: is there a difference between those released by the hematological analyzer and to the customer?

Objective: This study aimed to compare the hematological parameters released by hematological analyzers with those released in customer reports.

Methods: We conducted a descriptive study in the laboratories of a medium-sized municipality in the state of Minas Gerais registered in the National Register of Health Establishments. Interviews were conducted using a questionnaire to obtain information regarding the parameters released by the analyzers and those available in the customer's report.

Plasma immune mediators as laboratorial biomarkers for Sickle Cell Disease patients according to the hydroxyurea therapy and disease severity.

In the present work, the impact of Sickle Cell Disease (SCD) degrees of severity, as well hydroxyurea treatment on the systemic immunological signatures of patients was evaluated. Based on a high-throughput chemokine, cytokine and growth factor multiplex analysis, it was possible to obtain the systemic immunological profile of patients with SCD (n = 40), treated or not with hydroxyurea, as compared to healthy controls (n = 40). Overall, SCD patients with severe disease displayed increased levels of almost all biomarkers analyzed.

Biochemical Evaluation of the Effects of Hydroxyurea in Vitro on Red Blood Cells.

Hydroxyurea (HU) is a low-cost, low-toxicity drug that is often used in diseases, such as sickle cell anemia and different types of cancer. Its effects on the red blood cells (RBC) are still not fully understood. The in vitro effects of HU were evaluated on the biochemical parameters of the RBC from healthy individuals that were treated with 0.

Renin angiotensin system molecules and chemokine (C-C motif) ligand 2 (CCL2) in chronic kidney disease patients.

Introduction: Studies have shown that the renin angiotensin aldosterone system (RAAS) and inflammation are related to kidney injury progression. The aim of this study was to evaluate RAAS molecules and chemokine (C-C motif) ligand 2 (CCL2) in 82 patients with chronic kidney disease (CKD).

Methods: Patients were divided into two groups: patients diagnosed with CKD and patients without a CKD diagnosis.

Clinical Features and Maternal-fetal Results of Pregnant Women in COVID-19 Times.

Objective:  Coronavirus disease 2019 (COVID-19) is a disease caused by a newly discovered coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which usually leads to non-specific respiratory symptoms. Although pregnant women are considered at risk for respiratory infections by other viruses, such as SARS and Middle East respiratory syndrome (MERS), little is known about their vulnerability to SARS-CoV-2. Therefore, this study aims to identify and present the main studies on the topic, including the postpartum period.

Doffing personal protective equipment in times of COVID-19.

COVID-19, a disease caused by a coronavirus (SARS-CoV-2), has worried health authorities in Brazil and worldwide because of its high infectivity and rapid spread. Within this context, health care workers are at greater risk of infection for being in close contact with patients, which is inherent to their work activities. To reduce the risk, protective measures must be adopted and personal protective equipment is essential.

Impact of oral hygiene in patients undergoing mechanical ventilation in the COVID-19 pandemic.

COVID-19, caused by SARS-CoV-2, can present respiratory complications that often lead patients to depend on mechanical ventilation (MV) for several days. It is known that Pneumonia Associated with Mechanical Ventilation (PAMV) is frequent in patients who use this equipment for a long time. As a consequence of COVID-19, its prolonged use can lead to a worse prognosis for the patients.

COVID-19: Review and hematologic impact.

In the last decades, coronaviruses have been a major threat to public health worldwide. SARS-CoV-2 is the third known coronavirus that causes fatal respiratory diseases in humans. The initial clinical features of SARS-CoV-2 infection are quite nonspecific and not all suspected patients can be tested to exclude or confirm the diagnosis.
