Summary
Urine neutrophil gelatinase-associated lipocalin (NGAL) is detectable in premature infants. Higher urine NGAL levels correlate with earlier gestational ages and lower birth weights, suggesting potential as an acute kidney injury biomarker.
Area of Science:
- Neonatal Medicine
- Nephrology
- Biomarker Research
Background:
- Premature infants face heightened risks for acute kidney injury (AKI) due to immature organ systems and medical interventions.
- Current AKI diagnostic methods are challenging in neonates due to unique physiological factors.
- Novel biomarkers are needed for early AKI detection in this vulnerable population.
Purpose of the Study:
- To assess the detectability of urine neutrophil gelatinase-associated lipocalin (NGAL) in premature infants.
- To correlate urine NGAL levels with gestational age, birth weight (BW), and indomethacin exposure.
- To explore the potential of urine NGAL as an early biomarker for AKI in neonates.
Main Methods:
- Enrollment of 20 premature infants across four birth weight (BW) groups (500-1500 g).
- Daily urine collection for the first 14 days of life.
- Analysis of urine NGAL levels and correlation with clinical parameters like gestational age and BW.
Main Results:
- Urine NGAL was readily detectable in all premature infants studied.
- Significantly higher urine NGAL levels were observed in neonates with earlier gestational ages and lower BWs (p < 0.01).
- No mention of correlation with indomethacin exposure in the provided abstract text.
Conclusions:
- Urine NGAL is easily obtainable from premature infants.
- Urinary NGAL levels significantly correlate with BW and gestational age in neonates.
- Further investigation into urine NGAL as a biomarker for AKI in premature infants is warranted.

The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease.

01:27Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
01:17Urinary Tract Infection IV: Nursing Management
In managing urinary tract infections (UTIs) in nursing, a comprehensive assessment is essential. Begin by gathering subjective data, such as the patient’s complaints of dysuria (painful urination), urinary frequency, urgency, suprapubic pain, and any lower abdominal discomfort. This information can be complemented by questions regarding previous UTIs, sexual activity, and personal hygiene practices, which can provide insight into risk factors. Objective assessment should focus on signs like...
01:28Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...
01:21Nursing Assessment of the Genitourinary System I: Health History
The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1. Gathering Patient InformationA complete health history includes the patient’s personal,...
