概括
婴儿肉毒主义 (IB) 患者很少表现出Clostridioides difficile共同殖民. 患有IB的双胞胎发生了无症状的C. difficile殖民,突出了其在婴儿微生物组中的持久性和传播.
科学领域:
- 微生物学 微生物学
- 传染性疾病 传染性疾病
- 儿科 儿科 儿科
背景情况:
- 婴儿肉毒症 (IB) 是一种罕见但严重的疾病,由Clostridium botulinum引起. 与其他肠道病原体共同殖民可能会使诊断和管理复杂化.
- 困难杆菌是医疗相关感染的重要原因,特别是在婴儿和免疫受损的人群中.
研究的目的:
- 调查疑似婴儿肉毒主义的婴儿中Clostridioides difficile共同殖民的流行情况.
- 在被诊断为IB和C. difficile共同殖民的婴儿双胞胎中纵向追踪C. difficile的殖民化.
主要方法:
- 从怀疑IB的107名婴儿的便样本中培养了C. botulinum和C. difficile.
- 在确诊IB和C. difficile共殖的双胞胎婴儿身上进行了纵向便培养,以确定每个生物体存在的持续时间.
- 使用限制性内核酶分析 (REA) 来类型化C. difficile分离物.
主要成果:
- 双胞胎X和Y被C. botulinum殖民了大约3-4个月,C. difficile殖民了7-8个月.
- 持续的C. difficile殖民被观察到,因为C. botulinum殖民减少了.
- 双胞胎共享四种相同的REA类型的C. difficile,包括流行病菌株类型J9. 双胞胎中没有一个患有C. difficile相关的疾病.
结论:
- 克洛斯特里迪奥伊德困难共殖民症很少在确诊的婴儿肉毒主义的婴儿中观察到.
- 婴儿肉毒症之后,在研究中的双胞胎中出现了无症状的C. difficile殖民.
- 这一案例凸显了C. difficile在密切接触者之间传播的潜力,并在婴儿肠道微生物群中持续存在,即使不会引起疾病.

The Colonization of Land
37.6K
Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

Drug Dosing: Infants and Children
293
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Patient-centered Care
3.0K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Drug Dosing: Geriatric Patients
269
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Drug Dosing: Obese Patients
263
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Pharmacodynamics in Geriatric Patients: Effects of Age
235
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
