Assessment of stature has been a neglected part of the medical assessment of individuals with spinal cord injury (SCI). In past studies of pulmonary function in SCI, it has not been stated how stature was assessed in order to calculate predicted pulmonary function. As part of a study of respiratory function in SCI, we examined the accuracy of self-report of stature and whether upper extremity measurements could be used to predict stature in 88 individuals with SCI. Although armspan and four other upper extremity measurements were significant predictors of length, recalled height was the best predictor. On average, for any value of armspan, an individual with complete SCI was 2.3 cm shorter than an individual with incomplete SCI. Individuals with complete SCI also had greater differences between recalled height and measured length compared with individuals with incomplete SCI, and this difference was not due to age or years since injury. It is likely that differences in bone demineralization account for the differences in length comparing individuals with complete and incomplete SCI. The 95 percent confidence intervals for predicted values of length based on armspan or recalled height were too wide for accurate calculation of predicted pulmonary function. In order to classify accurately the extent of pulmonary function abnormality, we suggest that measurements of supine length be made part of the medical assessment of individuals with SCI.

Deficient neutrophil responses early in influenza infection promote viral replication and pulmonary inflammation.

Neutrophils play key protective roles in influenza infections, yet excessive neutrophilic inflammation is a hallmark of acute lung injury during severe infections. Phenotypic heterogeneity is increasingly recognized in neutrophil populations; however, how functional variation in neutrophils between individuals determine the diverse outcomes of influenza remains unclear. To examine immunologic responses that may drive varying outcomes in influenza, we infected C57BL/6 (B6) and A/J mice with mouse-adapted influenza A virus A/PR/8/34 H1N1.

Central venous pressure as a method of optimising atrio-ventricular delay after cardiac surgery.
PLoS One

National Heart and Lung Institute, Imperial College London, London, United Kingdom.
Introduction: Haemodynamic atrioventricular delay (AVD) optimisation has primarily focussed on signals that are not easy to acquire from a pacing system itself, such as invasive left ventricular catheterisation or arterial blood pressure (ABP). In this study, standard clinical central venous pressure (CVP) signals are tested as a potential alternative.
Methods: Sixteen patients with a temporary pacemaker after cardiac surgery were studied.

The pathogenesis of chronic thromboembolic pulmonary hypertension may be multifactorial and requires further studies. We explored alterations in pulmonary artery endothelial cells under the hypoxic and elevated interleukin-17 conditions that are commonly present in patients with chronic thromboembolic pulmonary hypertension. We measured the serum interleukin-17 levels in 10 chronic thromboembolic pulmonary hypertension patients and 10 healthy control persons.

Disruption of developmental processes affecting the fetal lung leads to pulmonary hypoplasia. Pulmonary hypoplasia results from several conditions including congenital diaphragmatic hernia (CDH) and oligohydramnios. Both entities have high morbidity and mortality, and no effective therapy that fully restores normal lung development.
