Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

484
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:

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

156
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Confounding in Epidemiological Studies01:27

Confounding in Epidemiological Studies

218
Confounding in statistical epidemiology represents a pivotal challenge, referring to the distortion in the perceived relationship between an exposure and an outcome due to the presence of a third variable, known as a confounder. This variable is associated with both the exposure and the outcome but is not a direct link in their causal chain. Its presence can lead to erroneous interpretations of the exposure's effect, either exaggerating or underestimating the true association. This...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

297
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...

Area of Science:

  • Ophthalmology
  • Infectious Diseases

Background:

  • Brucellosis is a systemic infection with potential ocular manifestations.
  • Ocular involvement can range in severity and impact visual function.

Purpose of the Study:

  • To investigate the spectrum of ocular involvement in brucellosis.
  • To highlight key diagnostic and management considerations for ophthalmic brucellosis.

Main Methods:

  • A systematic review of English-language literature published in the last 30 years.
  • Literature search conducted on the PubMed database using relevant keywords.

Main Results:

  • Analysis of 27 publications involving 159 cases of ocular brucellosis.
  • Uveitis (52.2%) and conjunctivitis (17.6%) were the most frequent ocular manifestations.
  • Serological tests were the primary diagnostic method (92.4%), with 37.1% of patients experiencing sequelae.

Conclusions:

  • Brucellosis presents diverse ophthalmic manifestations that require timely diagnosis.
  • Delayed diagnosis can lead to irreversible vision impairment and sequelae.
  • Routine ophthalmologic screening is recommended for all patients diagnosed with systemic brucellosis.
