Insights

A new clinical scale effectively assesses infant sucking, swallowing, and respiration, aiding in classifying feeding issues. This reliable tool helps identify nutritional challenges in infants with abnormal sucking patterns.

Area of Science:

  • Pediatric Nutrition
  • Clinical Assessment Tools
  • Infant Feeding

Background:

  • Suck dysfunction in infants can impede adequate nutrition.
  • Accurate assessment of infant feeding is crucial for growth and development.

Purpose of the Study:

  • To develop and validate a clinical nutritional sucking scale.
  • The scale focuses on the interconnected components of sucking, swallowing, and respiration.

Main Methods:

  • The scale underwent face and psychometric validation.
  • 179 healthy newborns and 26 infants under 6 months, plus 86 high-risk infants, were evaluated.
  • Inter-observer concordance and internal consistency were analyzed, refining the scale to 7 items.

Main Results:

  • The 7-item scale demonstrated high reliability (Cronbach's alpha=0.77, inter-observer concordance=0.98).
  • Sucking correlated with ingested volume (r=0.61), swallowing with oxygen saturation (r=0.24), and breathing with respiratory rate (r=0.50).
  • The scale identified patterns of sucking abnormalities linked to neurological, hemodynamic, and immaturity factors.

Conclusions:

  • The clinical nutritional scale is reliable and valid for classifying infant sucking problems.
  • Further research is needed to explore its use in oral stimulation therapies.

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...

Assessment of the Gastrointestinal System II: Health Perception Pattern

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Data Validation

Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
Nursing assessment guides are generally based on holistic models rather than medical...

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...

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.
