Impact of bilateral mediastinal lymph node dissection on pulmonary function during the early postoperative period after curative-intent lung surgery for cancer: a randomized study.

Background: Bilateral lymph node dissection is not a standard surgical treatment for non-small cell lung carcinoma. However, data from anatomical studies showing lymph flow to the contralateral mediastinal lymph nodes have prompted attempts to extend lymph node dissection to the contralateral mediastinum. Little is known about the functional effects of extended lymphadenectomy.

The Associations of Perceived and Oxidative Stress with Hypertension in a Cohort of Police Officers.

Purpose: Associations between perceived stress and oxidative stress marker and metabolic syndrome (MetS) components were investigated in a cohort of police officers.

Methods: Cross-sectional data from a cohort of non-diabetic subjects (n=233; 19F), median [interquartile range] age 50 [37-44] years, were analysed. MetS was construed in line with International Diabetes Federation (IDF) criteria and perceived stress with Cohen's 10-item Perceived Stress Scale.

Potential roles of psychological and oxidative stress in insulin resistance: a cohort-based study.

Background: The present study investigated the relationships between psychological stress indices and oxidative stress marker, also when combined with emergent insulin resistance (IR), in the non-diabetic, middle-aged subjects, exposed to frequent/chronic psychological stressors.

Methods: Cross-sectional data from a cohort of non-diabetic police officers (n = 234; 19F), aged 27-56 years, were used. Plasma inflammatory (CRP, TNF-α), oxidative stress (free 8-iso-prostaglandin F; 8-iso-PGF) markers, and insulin were measured.

The Relationship of Metabolic Syndrome with Stress, Coronary Heart Disease and Pulmonary Function--An Occupational Cohort-Based Study.

Background And Aims: Higher levels of stress impact the prevalence of metabolic syndrome (MetS) and coronary heart disease. The association between MetS, impaired pulmonary function and low level of physical activity is still pending assessment in the subjects exposed to stress. The study aimed to examine whether higher levels of stress might be related to MetS and the plaque presence, as well as whether MetS might affect pulmonary function.
