- 妊婦と胎児の医療
背景:
- 胎児には重大なリスクがあります
- 早期出産の危険因子とタイミングを把握することは 結果の改善に不可欠です
- 乳腺膜の破裂は 早期出産の 異なる経路を表しています
研究 の 目的:
- 胎内膜の陽性,自発的,早産前破裂の危険因子と出産タイミングを調査する.
- ニュー・サウス・ウェールズ州の保健サービスにおける早産管理の違いを分析する.
- 母親の特徴と異なるタイプの早産との関連を特定する.
主な方法:

- 113,244人のシングルトン妊娠を含む.
- 多変量ロジスティックとコックス回帰モデルで,早産の発生率と発生までの時間を分析する.
主要な成果:
- 妊娠の7.0%が早産 (7940例) であった.
- イアトロゲン性早産が最も一般的であった (49. 2%),次に自発的 (36. 9%) と早産前膜破裂 (13. 9%).
- 過去の早産と産前ケアモデルは,すべての早産タイプに関連していました. 病院の容量は,特定のタイプの出産タイミングに影響しました.

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...

Relative Risk
342
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
675
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:

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
174
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,...

Factors Affecting the Risk of Infection
12.3K
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...

Longitudinal Research
12.5K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
