Enteral Nutrition I: Orogastric and Nasogastric Feeding01:26

Enteral Nutrition I: Orogastric and Nasogastric Feeding

262
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...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

119
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.

mTOR Signaling and Cancer Progression

3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Summary
This summary is machine-generated.

Sarcopenia, or loss of skeletal muscle mass, predicts feeding tube placement in oropharyngeal cancer patients. Muscle mass at the T4 vertebra is a key indicator for nutritional support needs during treatment.

Area of Science:

  • Oncology
  • Radiotherapy
  • Nutritional Science

Background:

  • Sarcopenia is a significant prognostic factor for survival in oropharyngeal squamous cell carcinoma (OPSCC).
  • The link between sarcopenia and nutrition-related outcomes, such as feeding tube dependence, is not fully understood in OPSCC.
  • Understanding these relationships is crucial for optimizing patient care and nutritional support.

Purpose of the Study:

  • To investigate the prognostic significance of sarcopenia for feeding tube (FT) placement in OPSCC patients.
  • To evaluate the association between baseline sarcopenia and the need for nutritional support during radiation therapy (RT) or chemoradiation therapy (CRT).

Main Methods:

  • Retrospective cohort study of 194 OPSCC patients treated with RT or CRT.
  • Sarcopenia assessment using computed tomography (CT) imaging at C3 and T4 vertebral levels.

  • Logistic regression analysis to explore the relationship between sarcopenia and FT placement.

    • Main Results:

    • Sarcopenia was prevalent at baseline (72.7% at C3, 41.7% at T4).
    • Patients with sarcopenia were significantly more likely to require FT placement.
    • Sarcopenia assessed at the T4 level was a significant predictor of FT placement.

    Conclusions:

    • Skeletal muscle mass (SMM) measured at the T4 vertebra may serve as a practical biomarker for sarcopenia.
    • Sarcopenia detection at baseline can inform decisions regarding nutritional support for OPSCC patients undergoing RT/CRT.
    • Early identification of sarcopenia can guide proactive nutritional interventions to improve outcomes.
