Observational Studies01:11

Observational Studies

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One example of...
Study Designs in Epidemiology01:20

Study Designs in Epidemiology

Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.
Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
Guidelines For Measuring Vital Signs01:19

Guidelines For Measuring Vital Signs

Following these guidelines can help nurses accurately measure vital signs, assess changes in patient conditions, and provide timely treatment when necessary. Adhering closely to the guidelines ensures the accuracy and reliability of the results.
Before taking a patient's vital signs, a nurse would consider and assess the patient's comfort level and ensure appropriate equipment is available.
Clinical Trials: Overview01:11

Clinical Trials: Overview

Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
Ethics in Research01:56

Ethics in Research

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Area of Science:

  • Epidemiology
  • Medical Research

Background:

  • Inadequate reporting of observational studies hinders assessment of their quality and generalizability.
  • The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) initiative developed a 22-item checklist to improve study descriptions.

Purpose of the Study:

  • To present the Portuguese translation of the STROBE Statement.
  • To discuss the context, potential, and limitations of the STROBE initiative in Brazil.

Main Methods:

  • Translation and adaptation of the STROBE Statement into Portuguese by Brazilian researchers.
  • Review and discussion of the initiative's applicability.

Main Results:

  • Successful translation and adaptation of the STROBE Statement into Portuguese.
  • Identification of the STROBE Statement's potential benefits for Brazilian epidemiological research.

Conclusions:

  • The Portuguese STROBE Statement facilitates more accurate and complete reporting of observational studies in Brazil.
  • Adoption of the STROBE Statement can enhance the quality and impact of epidemiological research in the Portuguese-speaking community.
