Insights

Infants born preterm face higher risks of kidney disease and hypertension. New guidelines recommend kidney evaluations before NICU discharge and at age two for preterm infants, especially those born very early or with specific health issues.

Area of Science:

  • Neonatology
  • Nephrology
  • Public Health

Background:

  • Preterm birth (<34 weeks gestation) is linked to increased risks of chronic kidney disease (CKD) and hypertension later in life.
  • Current follow-up protocols for neonatal kidney health are inconsistent, leading to potential gaps in early detection and management.
  • The Neonatal Kidney Health Consensus Workshop convened experts to address these critical issues.

Purpose of the Study:

  • To review existing evidence on kidney health outcomes in preterm infants.
  • To identify knowledge gaps in the follow-up care of this population.
  • To develop consensus-based recommendations for optimizing neonatal kidney health surveillance.

Main Methods:

  • A multidisciplinary expert group convened in February 2024.
  • Evidence review and synthesis on kidney health in preterm infants.
  • Development of consensus recommendations for follow-up care.

Main Results:

  • Key recommendations include kidney evaluation before NICU discharge and at two years of age.
  • Comprehensive assessment is advised for high-risk infants (e.g., born <28 weeks, with AKI, IUGR, SGA).
  • Emphasis on evidence-based parental education for early CKD detection and management.

Conclusions:

  • The consensus provides a framework for optimizing kidney health follow-up in preterm infants.
  • Highlights research priorities for improved risk stratification, early diagnosis, and interventions.
  • Aims to mitigate long-term risks of CKD and hypertension in this vulnerable population.

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

Acute Kidney Injury III: Clinical Manifestations

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
