Decreased body mass index and restrictive lung disease in congenital thoracic scoliosis

Abstract

Pediatric patients with congenital thoracic scoliosis often have restrictive lung disease and low body weight for age. In other patients with respiratory disorders, the work of breathing can increase basal metabolic demands and predispose patients to cachexia. The primary study aim was to determine if severity of restrictive lung disease, as measured by pulmonary spirometry, correlates to decreased body mass index (BMI) in patients with congenital thoracic scoliosis. A secondary study aim was to determine what patient factors and radiographic measures correlate to low BMI. Forty-nine consecutive patients with congenital thoracic scoliosis underwent pulmonary function testing, spinal radiographs, and BMI percentile for age calculations. Severity of restrictive lung disease was quantified by the forced vital capacity percentile (FVC%). The BMI percentile for age was also ranked as normal, moderately, or markedly decreased (0, <1, or <2 SDs below normal, respectively). The t tests were performed between BMI rank and FVC% as well as forced expiratory volume in 1 second (FEV1). A stepwise multivariate linear regression analysis was performed between BMI percentile and FVC%, age, sex, type and extent of previous spine fusion, radiogr...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Cardiac Cachexia

Cardiac cachexia is a syndrome associated with the progressive loss of muscle and fat mass. It most commonly affects patients with heart failure and can significantly decrease the quality of life and survival in these patients. Here is the latest research on cardiac cachexia.

Cachexia & Brown Fat

Cachexia is a condition associated with progressive weight loss due to severe illness. In cancer patients, it is proposed to occur as a result of tumor-induced energy wasting. Several proteins have been implicated in browning and depletion of white adipose tissue. Here is the latest research on cachexia and brown fat.
