Summary
Noncephalic presentation in preterm delivery increases neonatal death risk, particularly in the neonatal intensive care unit (NICU) or by 15 months corrected gestational age (cGA). However, it also reduces the risk of intraventricular hemorrhage (IVH).
Area of Science:
- Perinatology
- Neonatology
- Obstetrics
Background:
- Preterm delivery presents significant challenges for neonatal outcomes.
- Fetal presentation, specifically noncephalic (non-head-first) positions, may influence delivery risks.
- Understanding these risks is crucial for optimizing care in preterm infants.
Purpose of the Study:
- To evaluate the impact of noncephalic presentation on neonatal outcomes in preterm deliveries.
- To compare neonatal outcomes between noncephalic and cephalic presentations in a preterm cohort.
Main Methods:
- Secondary analysis of the BEAM trial data.
- Inclusion of women with singleton, liveborn, nonanomalous fetuses.
- Logistic regression used to calculate adjusted odds ratios and confidence intervals for neonatal outcomes, controlling for confounders.
- Stratified analysis by mode of delivery performed.
Main Results:
- 458 noncephalic deliveries were compared to 1,485 cephalic deliveries.
- Noncephalic presentation was linked to increased risk of neonatal intensive care unit (NICU) death or death by <15 months corrected gestational age (cGA).
- A decreased risk of intraventricular hemorrhage (IVH) was observed in noncephalic presentations.
- Increased risk of death persisted in stratified analyses, particularly for cesarean deliveries.
Conclusions:
- Noncephalic presentation in preterm infants is associated with a higher risk of mortality (<15 months cGA and NICU death).
- The risk of intraventricular hemorrhage (IVH) is reduced with noncephalic presentation.
- Mode of delivery does not negate the increased mortality risk associated with noncephalic presentation.

Self-presentation is a fundamental aspect of social interaction, shaping both how others perceive individuals and how they view themselves. This dynamic process influences behaviors in various social settings, often leading people to adjust their appearance, speech, and demeanor to align with their desired identity. While self-presentation can be deliberate or unconscious, it plays a critical role in interpersonal relationships and self-perception.Forms of Self-PresentationSelf-presentation can...

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...

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Strategic self-presentation refers to individuals' intentional efforts to influence how others perceive them. This process is employed in various social and professional settings, such as job interviews, dating, politics, and legal contexts, where individuals seek to shape impressions to gain social or material advantages. While people generally present themselves in ways that align with their authentic characteristics, external factors, such as cognitive load, can hinder their ability to...

Effective self-presentation is a central component of social interaction and identity construction. It relies on the dynamic processes of defining the situation and engaging in self-disclosure. These mechanisms help individuals navigate social context expectations and manage how others perceive them, fostering mutual understanding and relationship development.Defining the SituationSocial situations are shaped by collectively understood frames—a set of widely understood rules or...

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...
