Real-World Data on Health-Related Quality of Life Assessment in Patients With Breast Cancer Receiving Subcutaneous Trastuzumab.

Purpose: Trastuzumab, a humanized anti-human epidermal growth factor receptor 2 (anti-HER2) antibody delivered intravenously, has revolutionized the treatment of patients with breast cancer overexpressing HER2 protein. Recently, a newer subcutaneous formulation was shown to have comparable efficacy to the initial intravenous trastuzumab. In this study, we aimed to evaluate the impact of subcutaneous trastuzumab on the health-related quality of life (HRQoL) of patients diagnosed with early or metastatic HER2-overexpressing breast cancer.

Carcinoembryonic antigen and carbohydrate antigen 19-9 serum levels in non-small cell lung cancer.

Purpose: Τo investigate the potential diagnostic and prognostic role of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9) serum levels in non-small cell lung cancer (NSCLC).

Methods: One hundred consecutive patients with newly diagnosed primary NSCLC were included in this study (88 men and 12 women). Blood was drawn before any kind of treatment and the collected serum was processed using chemiluminescence in order CEA and CA 19-9 levels to be measured.

Tiotropium bromide exerts anti-inflammatory effects during resistive breathing, an experimental model of severe airway obstruction.

Introduction: Resistive breathing (RB), a hallmark of obstructive airway diseases, is characterized by strenuous contractions of the inspiratory muscles that impose increased mechanical stress on the lung. RB is shown to induce pulmonary inflammation in previous healthy animals. Tiotropium bromide, an anticholinergic bronchodilator, is also shown to exert anti-inflammatory effects.

Dose- and time-dependent effects of lipopolysaccharide on technetium-99-m-labeled diethylene-triamine pentaacetatic acid clearance, respiratory system mechanics and pulmonary inflammation.

Intratracheal administration of lipopolysaccharide (LPS) in animals is a commonly used model of acute lung injury, characterized by increased alveolar-capillary membrane permeability causing protein-rich edema, inflammation, deterioration of lung mechanical function and impaired gas exchange. Technetium-99-m-labeled diethylene-triamine pentaacetatic acid ((99m)Tc-DTPA) scintigraphy is a non-invasive technique to assess lung epithelial permeability. We hypothesize that the longer the exposure and the higher the dose of LPS the greater the derangement of the various indices of lung injury.

Lung compliance and chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease, namely, pulmonary emphysema and chronic bronchitis, is a chronic inflammatory response of the airways to noxious particles or gases, with resulting pathological and pathophysiological changes in the lung. The main pathophysiological aspects of the disease are airflow obstruction and hyperinflation. The mechanical properties of the respiratory system and its component parts are studied by determining the corresponding volume-pressure (P-V) relationships.
