Respiratory distress syndrome (RDS) causes pulmonary hypertension. It is often suggested that this increased afterload for the right ventricle (RV) might lead to cardiac dysfunction. To examine this, we studied biventricular function in an experimental model. RDS was induced by lung lavages in seven newborn lambs. Five additional lambs served as controls. Cardiac function was quantified by inde...

background: hairdressers are occupationally exposed to a number of agents in their workplace that result in respiratory symptoms and changes in pulmonary function. objective: to evaluate associations between occupational exposure and respiratory function and reported symptoms in a group of hairdressers compared to a control group. methods: a questionnaire on respiratory symptoms and workplace c...

Abstract Funding Acknowledgements Type of funding sources: None. Background Right ventricular myocardial work (RVMW) assessed by transthoracic echocardiography allows to study and analyze the right (RV) function non-invasively, using RV pressure-strain loops. The association between these novel indexes RVMW invasive hemodynamic parameters has not yet been extensively studied, namely in precapil...

chronic obstructive pulmonary disease (copd) is a public health problem worldwide. increased energy and protein needs, decreased energy and protein intake are common in copd patients. adequate intake is essential to improve pulmonary function and immune system, prevention of weight loss and maintaining muscle mass and strength. assessment of energy and protein intake and its relationship with p...

Objectives: This study was aimed to determine the Effect effect of incentive spirometry on pulmonary function tests in patients undergoing hemodialysis. Methods: This study was a randomized clinical trial conducted in on hemodialysis patients. The obtained Data were collected from 26 patients in the experimental and 26 patients in the control group. In The the control group, patients received ...

BACKGROUND Evidence suggestive of endoplasmic reticulum (ER) stress in the pulmonary arteries of patients with pulmonary arterial hypertension has been described for decades but has never been therapeutically targeted. ER stress is a feature of many conditions associated with pulmonary arterial hypertension like hypoxia, inflammation, or loss-of-function mutations. ER stress signaling in the pu...

BACKGROUND Systemic sclerosis–associated pulmonary artery hypertension (SScPAH) has a worse prognosis compared with idiopathic pulmonary arterial hypertension (IPAH), with a median survival of 3 years after diagnosis often caused by right ventricular (RV) failure. We tested whether SScPAH or systemic sclerosis–related pulmonary hypertension with interstitial lung disease imposes a greater pulmo...

background: workers in wastewater treatment plants are exposed to a wide range of chemicals as well as biological contaminants. objective: to ascertain whether exposure to bio-aerosols under the normal working conditions in wastewater treatment plants is associated with any significant changes in the prevalence of respiratory symptoms and lung function capacities. methods: 198 employees of wast...

introduction: metabolic syndrome (mets) and impaired lung functions have been associated with an increased risk for coronary heart disease. the aim of this study was to investigate the pulmonary functions in patients with mets. methods: this cross-sectional study included 200 subjects with mets in the study group and 100 subjects without mets in the control group. participants were examined at ...

Introduction: Hypertrophied tonsils and adenoids may cause upper airway obstruction and cardio-pulmonary complications due to pulmonary arterial hypertension. The aim of this study was to determine the correlation between mean pulmonary arterial pressure (mPAP) and selected adenotonsilar hypertrophy indexes. Materials and Methods: Thirty two patients with upper-airway obstruction resulting ...
