- 神经学 神经学
- 公共卫生 公共卫生
背景情况:
- 与艾滋病毒相关的加密球菌抗原血症对加密球菌脑膜炎和死亡率构成重大风险.
- 在资源有限的环境中,在无症状个体中,腰椎穿刺未得到充分利用,优先考虑有症状的患者.
- 评估密码球菌脑膜炎脑膜炎症状的预测价值至关重要.
研究的目的:
- 评估脑膜症状的预测价值,以诊断患有密码球菌抗原血的人的密码球菌脑膜炎.
- 确定关键的临床指标和生物标志物,用于早期检测加密球菌脑膜炎.
- 在资源有限的环境中改进诊断策略.
主要方法:

- 包括患有脑膜症状和脑脊液 (CSF) 加密球菌抗原 (CrAg) 测试的成年参与者.
- 利用后勤回归和分类树,评估接收器操作特征曲线 (AUROC) 下的区域和错误分类率.
主要成果:
- 在344名参与者中,83%的人头疼,60%的人脑膜炎. 中位数CrAg标位为1:1280.

Cranial and Spinal Meninges
4.1K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Patient-centered Care
3.1K
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
278
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
269
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
241
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...

Pharmacokinetics in Pediatric Patients: Drug Excretion
277
In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
