“…1 Published equations for children and adults were used to determine predicted values of FEV 1 and FVC. 16,17 As part of usual protocol, pretransplant and day 100 (80720 days) PFTs were obtained regardless of the presence or absence of symptoms. After discharge from our institution by day 100, patients were encouraged to follow-up at the Fred Hutchinson Cancer Research Center 1 year (3657100 days) after transplant.…”

Summary:The clinical significance of early airflow decline after myeloablative allogeneic hematopoietic SCT is uncertain. We performed a retrospective cohort analysis to determine if airflow decline by day 100 is associated with later development of transplant-related airflow obstruction (AFO) and increased mortality risk. Overall, 750 (40%) patients had airflow decline by day 100. Development of airflow decline by day 100 was associated with an increased risk for AFO at 1 year (relative risk 2.6, 95% confidence interval 2.1-3.1) but not with an increase in mortality risk (hazard ratio (HR) 0.86, P ¼ 0.05). However, patients with the fastest rate of decline between day 100 and 1 year (12.5% per year 724) had the highest mortality risk (HR 3.2, Po0.001). In conclusion, airflow measurements made on day 100 do not predict the rate of airflow decline between day 100 and 1 year, and therefore are not useful as a single measurement for determining mortality risk associated with development of AFO. Closer monitoring of the rate of airflow decline during the first year may facilitate the timely detection and treatment of early airflow decline and prevent the development of fixed AFO and increased mortality risk after hematopoietic stem cell transplant.

“…The anthropometric reference used was that of the National Center for Health 1 , respectively, via the three sets of equations used in this study. (7,21,22) The FVC values for normal weight females and underweight males predicted via the Hsu et al equation (22) were significantly higher than were the measured values. In normal weight, overweight and obese males, as well as in underweight, overweight and obese females, there were no differences between the measured FVC values and the FVC values predicted via the three sets of equations.…”

“…(17)(18)(19) However, there are studies showing that there is an increase in spirometric values in overweight or obese children. (12,20) The reference equations proposed by Polgar & Promadhat, (21) Hsu et al (22) and Mallozi (7) have been used to calculate pulmonary function values (FEV 1 and FVC) in children and adolescents. What these equations have in common is height 3 Statistics (NCHS), recommended by the World Health Organization.…”

“…The data were analyzed through measurements of central tendency, and an unpaired Student's t-test was used to describe the sample. One-way ANOVA was used to compare the FVC and FEV 1 values obtained using the equations mentioned above, (7,21,22) and Dunnett's post hoc test was used for multiple comparisons. The level of significance was set at 5% (p < 0.05).…”

Objective: To compare FEV 1 and FVC, calculated using three sets of reference equations (devised by Polgar & Promadhat, Hsu et al. and Mallozi in 1971, 1979 and 1995, and to determine whether the three are similar in predicting lung function in children and adolescents with distinct body mass indices (BMIs). Methods: The individuals were separated into four groups in accordance with the reference standards of the National Center for Health Statistics: underweight (UW), normal weight (NW), overweight (OW), and obese (OB
