Teratogenicity01:07

Teratogenicity

2.4K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Preventive Healthcare Services

1.0K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

11.8K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Healthcare Associated Infections II: Preventive Measures

2.6K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

126
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,...

Pre-Procedural Guidelines for Assessing Blood Pressure01:10

Pre-Procedural Guidelines for Assessing Blood Pressure

565
Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the...

Area of Science:

  • Obstetrics and Gynecology
  • Hematology
  • Maternal Health

Background:

  • Venous thromboembolism (VTE) is the primary cause of maternal mortality.
  • Pregnancy significantly elevates VTE risk, compounded by various established risk factors.
  • Current risk assessment relies on identifying these factors, but knowledge gaps persist regarding risk duration and factor interactions.

Purpose of the Study:

  • To provide an updated review of VTE risk factors during pregnancy and the postpartum period.
  • To highlight existing knowledge gaps in VTE risk assessment and prevention.
  • To discuss current strategies for VTE prevention in pregnant individuals.

Main Methods:

  • Review of recent evidence on pregnancy-associated VTE risk factors.
  • Analysis of current approaches to thromboprophylaxis in pregnant populations.
  • Identification of challenges in conducting clinical trials during pregnancy.

Main Results:

  • Established risk factors increase VTE risk in pregnancy, but their duration and interactions require further study.
  • High-quality data for VTE prevention strategies in pregnancy remains limited.
  • Recent trials have begun to address knowledge gaps, though challenges persist.

Conclusions:

  • Accurate VTE risk assessment in pregnancy is essential for targeted thromboprophylaxis.
  • Further research is needed to clarify risk factor duration, interactions, and evidence-based prevention strategies.
  • Addressing knowledge gaps is critical to reducing VTE-related maternal mortality.
