主要方法:
- 一项基于医院的前性研究,涉及1682名18岁以上的参与者,他们完成了首次COVID-19疫苗系列.
- 参与者被跟踪了一年,在第二剂后的1,6个月和12个月进行电话采访.
- 系统的随机抽样被用于招生,半结构化问卷收集了关于BTI的数据.
主要成果:
- 一年后,Covaxin的整体BTI率为3.0%,Covishield的3.5%,没有统计学上显著的差异 (p=0.624).
- 糖尿病或高血压等并发症与BTI风险增加没有显著关联 (aOR:1.219,p=0.891).
- BTI与疫苗类型,性别,就业状况或年龄类别没有显著关联.
结论:
- 接种COVID-19疫苗的类型 (Covishield或Covaxin) 在初级接种疫苗后一年没有显著影响突破性感染的风险.
- 未来的COVID-19制策略应该考虑人口面临类似风险,无论接种的疫苗类型如何.

01:12Analysis of Population Pharmacokinetic Data
387
Analysis of population pharmacokinetic data involves studying the behavior of drugs within diverse populations to understand their pharmacokinetic parameters. Traditional pharmacokinetic methods typically involve collecting samples from a few individuals and estimating these parameters. While these methods are commonly used, they have limitations in capturing the variability in drug response among individuals or heterogeneous populations. Population pharmacokinetics is employed to address these...

176
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,...

01:19Pharmacovigilance
996
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

01:08Prevalence and Incidence
818
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

01:16Bioequivalence: Overview
1.2K
Pharmaceutical equivalents, by definition, are drug products with the same active ingredient in the same quantities, encapsulated in identical dosage forms, and intended for the same administration routes. These pharmaceutical equivalents are deemed bioequivalent if the bioavailability of the active entity in the drug preparations is similar. Moreover, pharmaceutical equivalents demonstrating bioequivalence are also regarded as therapeutically equivalent. This means that when used as directed,...
