Association of RS1126478 (LTF) with molar-incisor and generalized periodontitis.

Objectives: LTF SNP rs1126478 (T>C) could modulate Lactoferrin function and release and has been associated with periodontal disease in different locations before, but not in America. Thus, this study aimed to assess the association between this SNP and Grade C Periodontitis (Generalized (PerioC-G) and Molar Incisor Pattern (PerioC-MIP)) and seek a relationship between its presence and LTF gingival crevicular fluid (GCF) production.

Material And Methods: Oral cells from 361 Brazilians and 375 North Americans patients (Diseased and Health Controls (PH) from both locations) were collected.

Knowledge and attitudes about dementia of primary care physicians in Southern Brazil.

Background: Primary Care Physicians have a central role in assisting individuals with dementia and evaluating their preparedness to care these patients is fundamental. Our aim is to evaluate the knowledge and attitudes regarding dementia of the Primary Care Physicians (PCP) in Rio Grande do Sul (RS) state, Southern Brazil.

Methods: We collected sociodemographic data, volume of patients with dementia treated/referred and perception of difficulties in caring for these patients.

Pneumococcal surface protein A (PspA) prevents killing of Streptococcus pneumoniae by indolicidin.

Pneumococcal surface protein A (PspA) is an important virulence factor in Streptococcus pneumoniae that binds to lactoferrin and protects the bacterium from the bactericidal action of lactoferricins-cationic peptides released upon lactoferrin proteolysis. The present study investigated if PspA can prevent killing by another cationic peptide, indolicidin. PspA-negative pneumococci were more sensitive to indolicidin-induced killing than bacteria expressing PspA, suggesting that PspA prevents the bactericidal action of indolicidin.

Effect of Tele-ICU on Clinical Outcomes of Critically Ill Patients: The TELESCOPE Randomized Clinical Trial.

Importance: Despite its implementation in several countries, there has not been a randomized clinical trial to assess whether telemedicine in intensive care units (ICUs) could improve clinical outcomes of critically ill patients.

Objective: To determine whether an intervention comprising daily multidisciplinary rounds and monthly audit and feedback meetings performed by a remote board-certified intensivist reduces ICU length of stay (LOS) compared with usual care.

Design, Setting, And Participants: A parallel cluster randomized clinical trial with a baseline period in 30 general ICUs in Brazil in which daily multidisciplinary rounds performed by board-certified intensivists were not routinely available.
