Regression Toward the Mean01:52

Regression Toward the Mean

6.3K
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...

Applications of Integration to Find Centers of Mass

183
Rotational equilibrium provides a natural framework for defining the center of mass of a system. For a plank balanced on a pivot with two unequal masses, equilibrium is achieved when the net torque about the pivot is zero. Torque is defined as the product of a force and its perpendicular distance from the pivot. When the torques due to all forces cancel, the pivot coincides with the center of mass of the system.For a system composed of several discrete point masses, the center of mass lies at...

Center of Mass: Introduction

17.2K
Any object that obeys Newton's second law of motion is made up of a large number of infinitesimally small particles. Objects in motion can be as simple as atoms or as complex as gymnasts performing in the Olympics. The motion of such objects is described about a point called the center of mass of the object. The center of mass of an object is a point that acts as if the whole mass is concentrated at that point. The center of mass of an object with a large number of infinitesimally small...

Significance of Center of Mass

6.1K
The center of mass of an object is defined as the mass-weighted average position of all the particles that comprise the object. The significance of the center of mass of an object can be seen by looking at its dynamics. The time derivative of the center of mass gives its velocity, assuming that the object's mass remains constant over time. Furthermore, the total linear momentum of an object can be seen as the linear momentum of a single particle of the object's total mass moving with...

Intrauterine Drug Delivery Systems01:21

Intrauterine Drug Delivery Systems

168
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...

Finding the Center of Gravity01:03

Finding the Center of Gravity

3.6K
The center of gravity of a body is an imaginary point where the body's total weight is assumed to be concentrated, and the body is perfectly balanced. The center of the mass of a body is a point at which the whole of the mass of the body appears to be concentrated. If the acceleration due to gravity, g, has the same value at all points on a body, its center of gravity is identical to its center of mass. The center of gravity of homogeneous bodies such as a sphere, cube, or rectangular plate...

Summary

Centering Pregnancy (CP) adoption requires understanding its core elements and addressing patient barriers. Readiness for this prenatal care model depends on system support, resources, and expertise for successful implementation.

Area of Science:

  • Obstetrics and Gynecology
  • Public Health
  • Healthcare Management

Background:

  • Centering Pregnancy (CP) is an effective prenatal care model.
  • Provider adoption of CP has been slow.
  • Adoption is hypothesized to depend on knowledge, personnel characteristics, patient impact, and system readiness.

Purpose of the Study:

  • To assess the impact of a CP seminar on knowledge and perceptions.
  • To identify barriers and facilitators to CP adoption.

Main Methods:

  • Matched, pretest-posttest, observational design.
  • 223 participants completed surveys.
  • Analysis of knowledge, barriers, and perceived value of CP.

Main Results:

  • Awareness of CP increased significantly post-seminar (from 34%).
  • Key knowledge gains included understanding group dynamics and facilitative leadership.
  • Top barriers were childcare, transportation, and language; patient benefits included timeliness and patient-centeredness.
  • Adoption readiness was influenced by costs, resources, and expertise.

Conclusions:

  • Readiness to adopt Centering Pregnancy requires dedicated support.
  • Start-up and sustainability are crucial for successful CP implementation.
