Primary Healthcare Services

1.9K
Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.
In 1978, international leaders convened in Alma-Ata, Kazakhstan, for what would be a pivotal event in global health. The Alma-Ata Declaration was the first to call...

Levels of Health Promotion and Illness Prevention

14.1K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Preventive Healthcare Services

1.8K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

439
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

There are various healthcare agencies in the United States—some of which are managed by religious institutions and others by different government branches.
Parish nursing is a growing specialty nursing profession that focuses on holistic healthcare, health promotion, and illness prevention. It blends professional nursing practice with a health ministry, focusing on health and healing within the context of a Christian community. Parish nurses serve as health educators, referral sources,...

Methods Of Healthcare Delivery System

3.9K
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

科学领域:

  • 神经科学和衰老研究研究
  • 微生物组和肠道健康
  • 营养科学与认知功能

背景情况:

  • 饮食模式显著影响认知能力下降和阿尔茨海默病风险.
  • 西式饮食 (WD) 与风险增加有关,而地中海饮食 (MeDi) 与风险降低有关.
  • 由饮食调节的肠道微生物群可能会调节这些效应,但研究持续时间不同,影响结果.

研究的目的:

  • 研究MeDi与WD对老老鼠认知功能的纵向影响.
  • 分析饮食对肠道微生物群组成随时间推移的影响.
  • 为了确定饮食诱导的微生物变化和认知表现之间的潜在联系.

主要方法:

  • 雄性Fischer344大鼠被随机分配到一个MeDi或WD长时间.
  • 在3.5个月,9.5个月和15.5个月使用莫里斯水迷宫 (MWM) 评估认知功能.
  • 通过16SrRNA测序收集和分析便样本,以分析肠道微生物群的组成.

主要成果:

  • 在3.5个月和9.5个月后没有观察到显著的认知差异.
  • 在15.5个月后,MeDi养的老鼠显示MWM延迟时间明显缩短,表明学习和记忆有所改善.
  • 截然不同的,取决于饮食的肠道微生物群组成在3.5个月后出现,随着时间的推移,Actinobacteria,Desulfobacterota和Firmicutes的显著变化. 在3.5个月和15.5个月的MeDi大鼠中,Firmicutes/Bacteroidetes比率较低.

结论:

  • 饮食对认知的影响取决于时间,只有在长时间暴露 (15.5个月) 后才观察到显著影响.
  • 衰老和饮食持续时间诱导了肠道微生物种群的微妙但渐进的变化.
  • 在15.5个月时,不同丰富的细菌与认知变化相吻合,代表了与饮食相关的认知状态的潜在微生物生物标志物.
