Chronic Kidney Disease III: Interprofessional Care

95
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...

Urinary Tract Calculi IV: Nutrition Therapy and Prevention

47
Management of renal calculi focuses on effective strategies like tailored nutrition and hydration therapy. Adjusting diet and fluid intake reduces stone formation and recurrence, making these interventions simple yet powerful in kidney stone prevention and management.Understanding Kidney StonesKidney stones form when calcium, oxalate, uric acid, and cystine concentrate and crystallize in urine. Factors contributing to their formation include genetic predisposition, certain medical conditions,...

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

443
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...

Overview of Protein Metabolism01:21

Overview of Protein Metabolism

2.1K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Proteins: Dietary Sources and Requirements

743
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...

Area of Science:

  • Sports Science
  • Nutrition Science
  • Physiology

Background:

  • Ramadan intermittent fasting (RIF) alters eating patterns, potentially affecting athletic performance.
  • Previous studies suggest RIF may negatively impact soccer-specific skills like speed, agility, and endurance.

Purpose of the Study:

  • To investigate the influence of a structured dietary plan during RIF on a professional soccer player's body composition and performance.
  • To assess the efficacy of an isocaloric diet with glycerol supplementation during Ramadan.

Main Methods:

  • A 20-year-old elite male soccer player (86.0 kg, 188.5 cm) participated.
  • The player followed a personalized, isocaloric diet plan supplemented with glycerol during Ramadan.
  • Lower limb strength and power were evaluated using Countermovement Jump (CMJ) and Abalakov Vertical Jump (ABK) tests pre- and post-Ramadan.

Main Results:

  • Body composition improved, showing a decrease in fat mass (6.61% to 5.70%) and an increase in muscle mass (50.26% to 51.50%).
  • Performance metrics enhanced, with CMJ height increasing from 36.72 cm to 40.00 cm and ABK height from 39.16 cm to 49.34 cm.

Conclusions:

  • Personalized nutritional strategies, including supplementation and rest, can mitigate negative effects of RIF on soccer players.
  • Optimized nutrition during Ramadan fasting can lead to significant improvements in body composition and physical performance in elite athletes.
