Summary
Perinatal stroke affects 9.6/100,000 live births, with risk factors like cesarean delivery and neonatal resuscitation identified. However, these factors don't fully explain stroke causes in term infants.
Area of Science:
- Neonatal neurology
- Pediatric epidemiology
- Public health
Background:
- Perinatal stroke is a significant concern in term infants.
- Identifying reliable risk factors for perinatal stroke is challenging.
- Existing risk factors are often present in healthy infants, complicating early detection.
Purpose of the Study:
- To determine the birth prevalence of perinatal stroke in term infants.
- To investigate potential risk factors associated with perinatal stroke.
- To understand the etiological pathways of perinatal stroke.
Main Methods:
- Prospective, population-based study design.
- Comparison of perinatal stroke data with Australian general population data.
- Statistical analyses including chi-squared tests, Fisher's exact tests, and multivariable logistic regression.
Main Results:
- Sixty cases of perinatal stroke were recorded between 2017 and 2019.
- The estimated birth prevalence was 9.6 per 100,000 live births annually.
- Significant risk factors identified include cesarean section, low 5-minute Apgar scores, neonatal resuscitation, and nulliparity.
Conclusions:
- Identified risk factors, while statistically significant, do not fully elucidate the causal mechanisms of perinatal stroke.
- The identified risk factors do not represent a direct causal pathway to stroke.
- Further validation through a case-control study is recommended to confirm these findings.

Factors Affecting Illness
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...

Factors Affecting the Risk of Infection
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 create...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
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, controlled...

Relative Risk
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...
Bias in Epidemiological Studies
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:
Hazard Ratio
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial evaluating a...
