The role of , and 1639 variants on the susceptibility of upper gastrointestinal bleeding: A full case-control study.

To investigate whether interindividual variability in the (*2 and *3 alleles) and (rs9923231) genes is associated with increased risk of upper gastrointestinal bleeding (UGIB) in users of non-steroidal anti-inflammatory drugs (NSAIDs) or low-dose aspirin (LDA). A full case-control study including 200 cases of patients diagnosed with UGIB and 706 controls was conducted in a Brazilian hospital complex. To perform an analysis of NSAIDs dose-effect, the defined daily dose (DDD) for NSAIDs was calculated in the 7-day etiologic window preceding the data index.

Traditional Lectures Actually Improve the Body of Knowledge, Skills, and Attitudes of Health Care Professional for Health Incident Reporting System.

A solid patient safety culture lies at the core of an effective event reporting system in a health care setting requiring a professional commitment for event reporting identification. Therefore, health care settings should provide strategies in which continuous health care education comes up as a good alternative. Traditional lectures are usually more convenient in terms of costs, and they allow us to disseminate data, information, and knowledge through a large number of people in the same room.

Extemporaneous Compounding: A Possible Trigger Tool to Detect Potential Health Incidents.

Background: Extemporaneous compounding (EC) involves the preparation of a therapeutic product for specific patient need. However, there is a potential relationship between this procedure and the occurrence of health incidents (HI). The use of trigger tools increases HI identification.

Genetic polymorphisms associated with upper gastrointestinal bleeding: a systematic review.

Non-variceal upper gastrointestinal bleeding (non-variceal UGIB) is a frequent and severe adverse drug reaction. Idiosyncratic responses due to genetic susceptibility to non-variceal UGIB has been suggested. A systematic review was conducted to assess the association between genetic polymorphisms and non-variceal UGIB.

Microbial contamination in herbal medicines: a serious health hazard to elderly consumers.

Introduction: The use of herbal medicine is on the rise worldwide, and safety issues associated with herbal medicines may have an exacerbated impact in elderly because this population has an increased susceptibility and sensitivity to health complications due to the aging process.

Methods: This cross-sectional study was carried out at a primary health care unit in the city of Macapa, Brazil. The herbal medicines used and the sociodemographic characteristics of 123 voluntarily consenting participants were collected using a structured questionnaire.

Phytopharmacovigilance in the Elderly: Highlights from the Brazilian Amazon.

Practices described as traditional medicine may coexist with formalized, science-based medicine. In this context, the present study aimed to verify the profile of the elderly who consumed herbal medicines concomitantly with medications and to identify suspected adverse drug reactions (ADRs) in the Brazilian Amazon (Macapá, Amapá). The study was carried out in two steps: a cross-sectional study (structured questionnaire) and a clinical study (pharmacotherapeutic follow-up).

Harmonization of Pharmacovigilance Regulation in Brazil: Opportunities to Improve Risk Communication.

Brazilian pharmacovigilance regulations involve 3 spheres: health services, Marketing Authorization Holders (MAHs), and sanitary agency. Drug tolerability began to be effectively assessed in Brazil after the founding of the National Agency of Sanitary Surveillance, which developed the Sentinel Network Project. The objective of the Sentinel Network Project is to increase the adverse drug reaction (ADR) reporting rate by health care professionals in the hospital setting.

Confounding Variables and the Performance of Triggers in Detecting Unreported Adverse Drug Reactions.

Purpose: This study explored the performance of trigger in detecting adverse drug reactions (ADRs), the confounding variables impairing the causal association of the ADRs, and the underreporting rate by hospital health professionals.

Methods: A 6-month cross-sectional study was conducted in a public general hospital. Data collection was conducted in 2 stages: (1) screening of patient hospitalizations to identify suspected ADRs with 9 triggers developed by the Institute of Healthcare Improvement; and (2) chart review to perform the causality assessment of the suspected ADRs identified, to describe the confounding variables associated with detection of suspected ADRs that were not drug induced, and to analyze the positive predictive value of triggers in recognizing ADRs.

Possible adverse drug events leading to hospital admission in a Brazilian teaching hospital.

Objectives: Drug safety problems can lead to hospital admission. In Brazil, the prevalence of hospitalization due to adverse drug events is unknown. This study aims to estimate the prevalence of hospitalization due to adverse drug events and to identify the drugs, the adverse drug events, and the risk factors associated with hospital admissions.
