简要总结
Malnutrition is a comorbidity oftenly seen in COPD patients who have progressive chronic inflammation and severity. The investigators aimed to determine the impact of nutritional status and nutrition-related factors on prolonged length of stay in hospitalized patients with acute respiratory failure and COPD. Nutritional status has been defined as an individual's health condition as it is influenced by the intake and utilization of nutrients (Todhunter, 1970). Nutritional status can be defined by energy balance, body composition and body function, moreover the chronic inflammation and the physical activity have an important role. In the study is used some tools (anthropometry, Nutritional Risk Screening [NRS 2002], food intake, body composition, Fat-Free Mass Index [FFMI], diaphragm ultrasound for evaluating diaphragmatic mobility, blood tests, hand) to define nutritional status. The investigatos'll analyze prevalance of malnutrition in the sample and the correlation of malnutrition with prolonged length of stay in hospitalized patients with acute respiratory failure and COPD.
详细描述
Introduction:
Chronic obstructive pulmonary disease (COPD) is a lung disease characterized by chronic obstruction of lung airflow that interferes with normal breathing and is not fully reversible. In Italy the disease frequency is growing, our last estimate by National Health Service in the year 2014 shows more than 6 cases on 100 people (6% of the population).
Materials and methods:
- Sample selection: 40 partecipants were enrolled in the Internal Medicine Department of S. Giovanni Calibita Fatebenefratelli Hospital in Rome
- Data collection: anamnesis (sex, age, GOLD classification, active pathologies, length of stay in hospital); Nutritional Risk Screening [NRS 2002]; food Intake: as pergentage of ingesta in the last meal; (MMRC) dyspnea scale.
- Anthropometry parameters: height , body weight, arm circumference, triceps skin fold thickness and Body Mass index was calculated [BMI = weight (Kg) / (stature (m))²]
- Body Composition: bioimpedance analysis (fat free mass, fat mass, phase angle, fat free mass index [height-normalized index of FFM, which is calculated by dividing FFM (in kg) by height (in m2) ]).
- Blood tests: albumin (g/dL), transferrin (mg/dL), prealbumin (mg/dL), lymphocytes /mm3, Retinol-binding protein (mg/dL), PCR (mg/L), NLR (neutrophil-lymphocyte ratio)
- Functional examinations: handgrip
- Diaphragm ultrasound performed during quiet respiration. The right diaphragm is analyzed through the liver window. The transducer is placed in the anterior subcostal region between the mid clavicular and anterior axillary lines. The ultrasound beam should reach the posterior part of the diaphragm. In the B mode view, the diaphragm is identified as an echogenic line between the interface of the lung and liver or spleen. Then, M mode is performed to record diaphragmatic excursion during respiration.
Statistics Demographic and clinical features were summarized with the descriptive statistic (mean, standard deviation, median, interquartile range) for continuous variables and with absolute frequencies and percentage for categorical variables. We used Chi-Square Tests or Fisher's Exact Test (if n < 5) for comparison of percentages. We used the Pearson or Sperman correlation to evaluate the relationship between the continuous variables.

结局指标
主要结局
Correlation between BMI (Kg/m2) and prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD
时间窗: Baseline
BMI is a tool to define nutritional status and its correlation with prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD is useful to understand the role of nutritional status in these patients
Correlation between arm circumference (cm) and prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD
时间窗: Baseline
Arm circumference is muscle mass related and is a tool to define nutritional status and its correlation with prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD is useful to understand the role of nutritional status in these patients
Correlation between dynapenia using handgrip strength test (Kg) and prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD
时间窗: Baseline
The dynapenia is a tool to define nutritional status and its correlation with prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD is useful to understand the role of nutritional status in these patients
Correlation between fat free mass (Kg) and prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD
时间窗: Baseline
Body composition (fat free mass) is a tool to define nutritional status and its correlation with prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD is useful to understand the role of nutritional status in these patients
Correlation between albumin (g/dL) blood serum level on prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD
时间窗: Baseline
Albumin is very influenced by nutritional status and low blood level means that nutritional status is not good
Correlation between food Intake: as pergentage of ingesta in the last meal and prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD
时间窗: Baseline
Food intake is a tool to define nutritional status and its correlation with prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD is useful to understand the role of nutritional status in these patients
Correlation between tricipital skin fold thickness (mm) and prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD
时间窗: Baseline
Tricipital skin fold thickness is a tool to define nutritional status and its correlation with prolonged length of stay (days) in hospitalized patients with acute respiratory failure and COPD is useful to understand the role of nutritional status in these patients
