Acute Kidney Injury I: Introduction01:22

Acute Kidney Injury I: Introduction

83
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

64
Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Acute Kidney Injury V: Interprofessional Care

51
Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

Acute Kidney Injury III: Clinical Manifestations

105
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...

Nephrotic Syndrome I : Introduction01:24

Nephrotic Syndrome I : Introduction

36
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Acute Kidney Injury II: Pathophysiology01:29

Acute Kidney Injury II: Pathophysiology

101
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Summary

Food insecurity (FI) is common in NICU families. Infants from food-insecure households face higher risks of acute kidney injury (AKI), slower AKI recovery, and elevated serum creatinine levels.

Area of Science:

  • Neonatal intensive care
  • Pediatric nephrology
  • Public health

Background:

  • Food insecurity (FI) affects a significant portion of families with neonates admitted to neonatal intensive care units (NICUs).
  • Understanding the impact of FI on neonatal health is crucial for improving patient outcomes.

Purpose of the Study:

  • To investigate the association between food insecurity (FI) and short-term kidney outcomes in neonates admitted to NICUs.
  • To compare the incidence of acute kidney injury (AKI) and serum creatinine (SCr) levels between neonates from food-insecure and food-secure households.

Main Methods:

  • A prospective cohort study was conducted with sequentially admitted neonates to two NICUs.
  • Maternal-neonatal dyads were assessed for FI status using the Hunger Vital Signs tool.
  • Kidney outcomes, including AKI, AKI recovery, and SCr at day 14, were compared based on FI status.

Main Results:

  • 39% of neonates were from households experiencing FI.
  • Infants from FI households had a significantly higher likelihood of early AKI (56% vs. 14%, p=0.002).
  • Neonates in FI households showed slower AKI recovery (66% vs. 17%, p=0.035) and elevated SCr at 2 weeks (66% vs. 17%, p=0.007).

Conclusions:

  • Food insecurity is prevalent among NICU-admitted neonates and is associated with adverse short-term kidney outcomes.
  • Neonates from FI households are at increased risk for AKI, delayed recovery, and elevated SCr.
  • FI screening and recognition are vital components of prenatal care and essential for understanding health disparities in neonatal kidney outcomes.
