Noncoding RNAs and Colorectal Cancer: A General Overview.

Colorectal cancer (CRC) is the second most prevalent cancer in the world in which nonmelanoma skin cases are not considered. Different epigenetic mechanisms play a role in the development of cancer. Noncoding RNAs (ncRNAs) are RNA molecules transcribed from noncoding regions of the genome.

Effects of alkaline water intake on gastritis and miRNA expression (miR-7, miR-155, miR-135b and miR-29c).

Unlabelled: It is known that abnormal expression of miRNAs in the gastric cancer (GC) contributes to its carcinogenesis. Therefore, ingestion of commercial (usual) water on a daily basis may be a contributing factor for the occurrence of alterations in the gastric mucosal. In this study, it was evaluated the expression of the miRNAs miR-29c, miR-7, miR-155, and miR-135b in the gastric tissue of patients with gastritis before and after the consumption of alkaline water (pH range from 8.

The sensitivity, specificity, and agreement of a point of care method: an assessment of the diagnostic accuracy.

The use of new technologies can improve screening in communities with difficult access to health. This article aims to evaluate the sensitivity, specificity, and agreement of a point of care test in comparison to laboratory methods for the determination of glucose (GLI), triglyceride (TG), and total cholesterol (TC) concentrations. This prospective study used data from the remaining adult population of quilombolas in Brazil.

Evaluation of the impact of single-nucleotide polymorphisms on treatment response, survival and toxicity with cytarabine and anthracyclines in patients with acute myeloid leukaemia: a systematic review protocol.

Introduction: Acute myeloid leukaemia is the most common type of acute leukaemia in the world. Thus, the study of genetic alterations, such as single-nucleotide polymorphisms (SNPs), has contributed to a better understanding of the mechanisms underlying leukaemogenesis, to improve the prognosis and to increase the survival of these patients. However, there is no synthesis of evidence in the literature evaluating the quality of evidence and the risk of bias in the studies such that the results can be translated.

A Comparative Review of Demographics, Incidence, and Epidemiology of Histologically Confirmed Intracranial Tumors in Brazil and Bulgaria.

Intracranial tumors (ICTs) attract numerous scientific teams and tremendous financial resources worldwide. These lesions of the central nervous system (CNS) can be both benign and malignant in biological behavior as well as local or metastatic in origin. We compared data from two studies on primary and metastatic ICTs from Brazil and Bulgaria, based on histopathologically confirmed ICTs from tertiary health centers.

Correlation Between Stress and Quality of Life Experienced by Caregivers: Perception of a Group of Healthcare Professionals.

Aim: This study aims to evaluate the relationship between perceived level of stress and quality of life of professionals working in Prompt Service Units in the city of Palmas, Tocantins.

Methods: A cross-sectional study was performed among 164 professionals from Prompt Service Units. Stress levels were evaluated using the Perceived Stress Scale.

What Is Different in the Population of the Brazilian Amazon Region so that They Have a Low Frequency of KRAS Gene Mutations?

Background: Colorectal cancer (CRC) has been described in the medical literature as resulting from many forms of interaction between lifestyle, genetics, and geographical origin. Genetically, the KRAS gene has a negative impact on the general survival and prognosis of patients when mutated.

Methods: This study was conducted in Brazil and included information about 60 patients with CRC stage III and IV examined at the Day Hospital Oncológica do Brasil, whose DNA was analyzed with the PCR-DNA method to determine the existence of a KRAS mutation.

Central nervous system tumours profile at a referral center in the Brazilian Amazon region, 1997-2014.

Tumours of the Central Nervous System (CNS) are an important cause of mortality from cancer. Epidemiological data on neoplams affecting the CNS are scarce in Brazil, especially in the Amazon region. The study aims at describing the histopathological profile of CNS tumours cases at a high-complexity referral cancer center.
