Preventive Healthcare Services

2.3K
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:

Chronic Kidney Disease III: Interprofessional Care

627
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Area of Science:

  • Pediatrics
  • Nutritional Science
  • Public Health

Background:

  • Rising global incidence of nutritional rickets and its long-term effects in children necessitates accurate prevalence data.
  • Current screening and diagnostic methods lack standardization, leading to variable prevalence estimates.
  • At-risk communities require reliable data to effectively address the condition.

Purpose of the Study:

  • To review the advantages and disadvantages of various screening tests for diagnosing rickets in community settings.
  • To identify the need for standardized methodologies in rickets prevalence determination.
  • To inform consensus-building among specialists for global rickets screening uniformity.

Main Methods:

  • Review of existing literature on screening tools and diagnostic criteria for nutritional rickets.
  • Analysis of the efficacy and limitations of clinical signs, biochemical markers (alkaline phosphatase, 25-hydroxyvitamin D), and radiographic findings.
  • Evaluation of the suitability of different methods for community-based screening.

Main Results:

  • Clinical signs may overestimate prevalence and are observer-dependent.
  • Alkaline phosphatase utility as a screening tool lacks consensus.
  • Measuring vitamin D status is generally considered unhelpful for rickets screening.
  • Radiographic findings are crucial for diagnosis but may be less effective in adolescents.

Conclusions:

  • Standardization of screening methodologies is essential for accurate global rickets prevalence data.
  • A consensus among public health specialists and pediatric endocrinologists is needed to establish best practices.
  • Improved methods are critical for identifying and managing rickets, especially in resource-limited areas.
