Observational Studies

11.3K
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...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

520
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,...

Bias in Epidemiological Studies

1.5K
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:

Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

4.2K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Nursing Assessment of the Genitourinary System I: Health History

543
The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1. Gathering Patient InformationA complete health history includes the patient’s personal,...

Summary
This summary is machine-generated.

Women with a history of bad obstetric history (BOH) face higher risks of complications like preterm delivery and hypertension. However, optimal antenatal care can lead to good outcomes in subsequent pregnancies.

Area of Science:

  • Obstetrics and Gynecology
  • Perinatal Medicine
  • Maternal-Fetal Medicine

Background:

  • Perinatal mortality remains a significant clinical challenge globally.
  • Women with a history of adverse pregnancy outcomes face increased risks in subsequent pregnancies.
  • Bad obstetric history (BOH) encompasses recurrent pregnancy losses and unexplained stillbirths/neonatal deaths.

Purpose of the Study:

  • To assess risk factors and pregnancy outcomes in women with BOH.
  • To compare outcomes between pregnancies with BOH and a control group.
  • To identify specific complications associated with BOH.

Main Methods:

  • A prospective study involving 79 pregnancies with BOH from 2003 to 2007.
  • Analysis of risk factors and outcomes including preterm delivery, stillbirth, mode of delivery, birth weight, and fetal distress.
  • Comparison with a randomly selected control group.
  • Intervention for identified risk factors such as hypothyroidism, hypertension, antiphospholipid antibody (APLA) syndrome, and gestational diabetes.

Main Results:

  • Significantly higher incidence of malpresentations, hypertension, APLA, cervical incompetence, preterm deliveries, and caesarean sections in the BOH group (p<0.05).
  • Identifiable risk factors were found in 59.49% of BOH cases; 40.51% had no probable cause identified.
  • Over 11% of patients in the BOH group had more than one identified risk factor.

Conclusions:

  • APLA, hypertension, malpresentation, cervical incompetence, preterm deliveries, and caesarean sections are significantly more prevalent in pregnancies with BOH.
  • While risk factors remain unidentified in a substantial percentage of BOH pregnancies, optimal antenatal care can lead to favorable outcomes.
  • Early identification and management of risk factors are crucial for improving pregnancy outcomes in women with BOH.
