Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Nature and Nurture

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...

Environmental Influences on Intelligence

Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children from...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Dimensions of Health and Illness

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

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

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 colonic...

Summary

Child nutritional deficiencies stem from complex, interconnected factors beyond just food scarcity. A revised model integrates child characteristics and mediating influences for a systems approach to understanding under-nutrition and obesity.

Area of Science:

Nutrition Science
Public Health
Developmental Psychology

Background:

Child under-nutrition and obesity are complex, multi-determined issues.
Traditional explanations often oversimplify the causes of nutritional deficiencies.
The UNICEF extended care model highlights family and caregiver resources as key factors.

Purpose of the Study:

To review the role of caregiver resources (maternal education, intelligence, depression) in child nutritional deficiencies.
To integrate child characteristics as additional influences on nutritional status.
To present a revised extended care model using a systems perspective.

Main Methods:

Literature review of factors influencing child nutritional deficiencies.
Application of a systems perspective to understand interrelationships between determinants.
Development of a revised extended care model integrating multiple influences.

Main Results:

Caregiver resources and child characteristics significantly influence nutritional deficiencies.
Mediating and moderating factors like cultural characteristics and social support networks play a crucial role.
A revised model explicitly integrates child characteristics and mediating/moderating links.

Conclusions:

A systems perspective is essential for understanding the complex web of influences on child nutrition.
The revised model provides a more comprehensive framework for studying nutritional deficiencies.
This approach can also be applied to understanding childhood obesity.
