Role of Amine and/or Tin-Containing Dentifrices on Tooth Discoloration and Surface Properties.

Objective: This study evaluated the impact of dentifrices containing amine fluoride (AmF) and/or tin on tooth discoloration and surface roughness under cycles of staining and abrasion.

Materials And Methods: Specimens of enamel (n = 10) and dentin (n = 19) were allocated into six groups: (1) Negative control (Distilled water), (2) NaF (regular fluoridated dentifrice without amine and tin), (3) AmF, (4) AmF/NaF/SnCl, (5) SnF/SnCl, and (6) SnF. Daily staining-toothbrushing cycling was performed: staining solution (30 min), toothbrushing (45 strokes), and human saliva (1 h), 2×/day, for 21 days.

Cholesterol, triglycerides, HDL, and nitric oxide as determinants of resting heart rate variability in non-hospitalized mild post-COVID individuals: a cross-sectional study.

Background: The association between plasma lipids, nitric oxide (NO) and cardiovascular risk has been well documented in the literature, however, the association between these outcomes and heart rate variability (HRV) in COVID-19 remains incipient as there is no scientific evidence that has investigated this outcome.

Objective: Investigate whether metabolic outcomes may be associated with cardiac autonomic behavior arising from short-term HRV variables in non-hospitalized mild post-COVID individuals.

Methods: This is a cross-sectional study.

Structural validity of the Brazilian version of the quality care questionnaire-palliative care for use in individuals with diabetes mellitus eligible for palliative care.

Background: The Brazilian version of the Quality Care Questionnaire-Palliative Care (QCQ-PC) is an instrument designed to assess the quality of care provided in palliative care from the user's perspective, featuring easy comprehension and applicability. It has demonstrated validity for use in individuals with cancer, but there is a need for validation in other populations due to the scarcity of instruments with this purpose.

Objective: To structurally validate the Brazilian version of the QCQ-PC for use in individuals with diabetes mellitus (DM) eligible for palliative care.

Congenital Horner and Scimitar syndrome in a newborn: a previously unreported combination.

Here we report a case of a term newborn presenting with left palpebral ptosis, anisocoria and heterochromia as well as cleft palate and heart murmur. Congenital Horner syndrome was suspected and a thoracoabdominal CT scan was performed to rule out neuroblastoma. This revealed an anomalous drainage of right pulmonary veins to a collector that drains to the inferior vena cava, leading to the diagnosis of Scimitar syndrome.

[Professional practices in situations of violence in home care: an integrative review].

This article aims to describe the practices of health professionals in situations of violence in the provision of home care. It involved an integrative review of the literature conducted between December 2016 and December 2017 in the LILACS, BDENF and MEDLINE databases. The sample was composed of 15 articles, organized and characterized by author, publication journal, country, year, title, method, main idea, category and level of evidence.

Low lineage diversity and increased virulence of group C subsp. .

In some species, the population structure of pathogenic bacteria is clonal. However, the mechanisms that determine the predominance and persistence of specific bacterial lineages of group C remain poorly understood. In Brazil, a previous study revealed the predominance of two main lineages of subsp.

A Role for Low-Density Lipoprotein Receptor-Related Protein 6 in Blood Vessel Regression in Wound Healing.

The healing of skin wounds is typified by a pattern of robust angiogenesis followed by vascular regression. Pigment epithelium-derived factor (PEDF), a recognized endogenous antiangiogenic protein, regulates vascular regression in resolving wounds through an unknown receptor. Among the multiple receptors for PEDF that have been identified, low-density lipoprotein receptor-related protein 6 (Lrp6) has been described as a regulator of angiogenesis in multiple systems.

Epistemology of nursing care: a reflection on its foundations.

Objective:: to reflect on nursing care and its epistemology from its historical, theoretical, philosophical, spiritual dimensions and as a social practice.

Method:: discussions originated in the discipline "Epistemology of caring", from the graduate nursing program of the School of Nursing, Federal University of Minas Gerais, and in critical analysis of nursing literature together with the professional practice of the authors.

Results:: we identified the necessity of developing a critical conscience on health care provision, research, and teaching, as well as on challenges in maintaining high standards of working interpersonal relationships, which has a profound impact on population health.

Effects of excess maternal thyroxin on the bones of rat offspring from birth to the post-weaning period.

Objective To evaluate, in rat offspring, bone changes induced by excess maternal thyroxin during pregnancy and lactation, and to assess the reversibility of these changes after weaning. Material and methods Twenty Wistar rats were distributed in two groups, hyperthyroid and control, that were treated daily with L-thyroxin (50 mcg/animal) and placebo, respectively. The treatment was initiated seven days before mating and continued throughout pregnancy and lactation.

[Relationship between the users' contact time in educational programs on diabetes mellitus and self-care skills and knowledge].

Objective: Check the relationship between the users' contact time in educational programs and self-care and knowledge variables in diabetes mellitus.

Method: A longitudinal study with a quantitative approach with the participation, in the initial phase, of 263 users linked to Basic Health Units in Belo Horizonte, Brazil during the years 2012 and 2013. The data were collected with respect to the total contact time of the users' participation in the educational program as regards knowledge and self-care in acquired diabetes mellitus.

The Use of Applications in Distance Education Specialization Course as a Support Tool for Students Living in Remote Areas Without Internet.

The world is experiencing the popularization of mobile devices. This was made possible by the increasing technological advances and the advent of the Internet as a communication and information tool. These facts demonstrate that the development of applications compatible with such devices is an effective way to provide content to diverse audiences.

Salivary retention after application of fluoride gel using toothbrush or tray: a crossover trial.

Currently, there are no studies in the literature evaluating salivary fluoride retention after small amounts of fluoride gel are applied to children's teeth. Therefore, the objective of the present study was to compare salivary retention after gel application using a toothbrush or by traditional application with trays. In this crossover study, children with active caries (n = 10) were randomized into one of the following treatment groups: a) application of fluoride gel using a tray (control), or b) application of fluoride gel with a toothbrush (treatment).
