Preventive Healthcare Services

1.2K
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:

Levels of Health Promotion and Illness Prevention

13.6K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Transmission-based Precautions II: Airborne and Protective Environment

1.6K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Regression Toward the Mean

6.5K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Birth Control Methods01:22

Birth Control Methods

3.6K
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Summary

Activity restriction (AR) does not prevent preterm birth (PTB) and carries risks. Current guidelines recommend against its routine use in pregnancy, favoring physical activity instead.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine
  • Reproductive Health

Background:

  • Activity restriction (AR) has historically been a common intervention for preventing preterm birth (PTB).
  • Recent evidence questions the efficacy and safety of AR, highlighting potential physical and psychological risks.
  • The practice has been re-evaluated due to a lack of demonstrated benefits in obstetrical and perinatal outcomes.

Purpose of the Study:

  • To review current data on the risks, benefits, and effectiveness of AR for PTB prevention.
  • To provide clinicians with an updated summary of evidence regarding AR.
  • To inform clinical practice on the appropriate management of PTB prevention strategies.

Main Methods:

  • Review of retrospective and prospective studies on AR and PTB.

  • Analysis of data concerning pregnancy duration, delivery mode, and maternal/neonatal outcomes.
  • Examination of recommendations from professional medical societies.

    • Main Results:

    • Studies show AR does not significantly prolong pregnancy in various high-risk scenarios.
    • Physical activity during pregnancy is linked to better outcomes, including higher vaginal delivery rates and lower risks of gestational diabetes and hypertension.
    • AR has not been shown to improve obstetrical or perinatal outcomes.

    Conclusions:

    • AR should not be routinely prescribed for PTB prevention.
    • Updated guidelines, such as the Society for Maternal-Fetal Medicine's 2020 recommendation, advise against routine AR.
    • Emphasis should be placed on promoting physical activity during pregnancy instead of restricting it.
