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,...

Proteins: Dietary Sources and Requirements

Proteins: Dietary Sources and Requirements

Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Chronic Kidney Disease III: Interprofessional Care

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Lipids: Dietary Sources and Requirements

Lipids: Dietary Sources and Requirements

Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ meats, shellfish,...

Metabolic States of the Body: Fasting and Starvation

Metabolic States of the Body: Fasting and Starvation

During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

Absorption of Nutrients

Absorption of Nutrients

Absorption refers to taking dietary nutrients from the intestinal lumen for transportation throughout the body. After digestion in the small intestine, carbohydrates, proteins, and fats are broken down into simpler forms. These essential macronutrients and other vital substances, such as vitamins, minerals, and water, are then prepared for absorption into the bloodstream.
Enterocytes, which are specialized polar epithelial cells, line the mucosa of the small intestinal walls. These cells...

Area of Science:

Gerontology
Nutritional Science
Public Health

Background:

The population of individuals aged 100 and older (centenarians) is rapidly expanding.
Investigating lifestyle factors, particularly diet and nutrition, is crucial for understanding exceptional longevity and maintaining health in advanced age.

Purpose of the Study:

To review dietary patterns and nutritional status of long-lived populations.
To assess nutritional biomarkers in centenarians compared to older adults.
To identify nutritional deficiencies and their predictors in centenarians.

Main Methods:

Systematic review of studies on dietary intake and nutritional biomarkers in centenarians.
Comparison of biomarker levels (antioxidant vitamins, vitamin B12, folate, homocysteine, 25(OH) vitamin D) between centenarians and control groups.
Analysis of demographic, dietary, and lifestyle factors influencing nutritional status.

Main Results:

Nutritional status and Body Mass Index (BMI) in centenarians are highly variable.
Biomarker levels, including antioxidant vitamins, vitamin B12, folate, homocysteine, and 25(OH) vitamin D, show heterogeneity.
Nutritional status is influenced by geographical region, demographics, diet, and lifestyle.

Conclusions:

Centenarian nutritional status is complex and influenced by multiple factors.
Further research is needed to elucidate the role of nutrition in promoting longevity and quality of life.
Understanding nutritional status is vital for supporting cognitive, mental, and physical health in extreme longevity.
