Insights

Improved nutritional practices, including increased breastmilk use, significantly enhanced growth velocity (GV) in preterm infants (<1500 g). This study tracked changes over 24 years, showing positive impacts on infant development.

Area of Science:

  • Neonatalogy
  • Pediatric Nutrition
  • Growth Monitoring

Background:

  • Preterm infants (<1500 g) face growth challenges.
  • Nutritional strategies significantly impact neonatal outcomes.
  • Longitudinal data is crucial for understanding growth trends.

Purpose of the Study:

  • To analyze changes in growth velocity (GV) for preterm infants (<1500 g).
  • To assess the impact of different nutritional practices on GV over 24 years.
  • To evaluate the role of breastmilk and breastfeeding rates in improving neonatal growth.

Main Methods:

  • Retrospective analysis of prospectively collected data (1990-2013).
  • Inclusion of 1651 preterm infants from a Spanish neonatal intensive care unit.
  • Generalized linear model adjusted for gestational age (GA) and small for gestational age (SGA); Tukey test for comparisons.

Main Results:

  • Significant increase in adjusted GV from 1990-2013 (3.27 ± 0.5 g/kg/day).
  • Average GA decreased significantly between 1990-1991 and 2012-2013.
  • Breastfeeding rates increased from 47.95% to 73.58% (2000-2013).

Conclusions:

  • Enhanced nutritional practices, particularly increased breastmilk utilization, improved GV in preterm infants.
  • The study highlights the positive correlation between breastfeeding rates and improved infant growth.
  • Nutritional interventions are key to optimizing growth outcomes in vulnerable preterm populations.

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Pneumonia V: Nursing management and Prevention

Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed....

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Role of Communication in the Nursing Process II: Planning and Implementation

Several factors are considered while creating a patient's care plan. Motivation is a factor in improving communication, and patients often require encouragement to try different approaches involving significant change. It is essential to involve the patient and family in decisions about the plan of care to determine whether the suggested methods are acceptable. Consider meeting critical comfort and safety needs before introducing new communication methods and techniques. Allow adequate time...

Oxygen Requirements and Growth Patterns

Microorganisms exhibit diverse oxygen requirements and growth patterns driven by their metabolic strategies and environmental adaptations. Oxygen, while essential for many organisms, can also be toxic under certain conditions, shaping how microorganisms grow and survive.Oxygen Requirements of MicroorganismsMicroorganisms are classified based on their ability to use or tolerate oxygen:● Obligate aerobes like Mycobacterium tuberculosis need oxygen for energy production, as it serves as the...
