Health Care Satisfaction: Effects of Immigration, Acculturation, Language.

Differences in health care satisfaction can alter patterns of health care utilization and so affect health outcomes, but little is known about variation in satisfaction in relation to immigration status. Health care satisfaction is analyzed with survey data from state public health program patients. Overall health care satisfaction is higher for first generation Hispanic immigrants and lower among those in the second generation compared to white Americans-consistent with the pattern termed the "healthy migrant effect.

Negative pleural suction in thoracic trauma patients: A randomized controlled trial.

Background: The study aimed to establish the benefits of using chest tubes with negative pleural suction against trapped water in patients with penetrating or blunt chest trauma who underwent tube thoracostomy, in terms of the incidence of complications, such as persistent air leak, clotted hemothorax, empyema, and duration of stay.

Methods: Patients who underwent tube thoracostomy because of traumatic pneumothorax, hemothorax, or hemopneumothorax were randomly assigned into one of two groups: in Group 1, the three-bottle drainage system was connected to a negative suction; in Group 2, no suction was given. Patients who required mechanical ventilation or emergency surgery (thoracotomy or thoracoscopy) either at the time of admission to the institution or immediately after the tube thoracostomy, patients who had histories of thoracic procedures or chronic pulmonary diseases (chronic obstructive pulmonary disease, diffuse interstitial lung disease), and patients with multiple injuries with severe traumatic brain injury and a Glasgow Coma Scale (GCS) score less than 8 of 15 were excluded from the study.

Mycobacterium tuberculosis antigens specifically modulate CCR2 and MCP-1/CCL2 on lymphoid cells from human pulmonary hilar lymph nodes.

Macrophages and dendritic cells are involved in the immune response to Mycobacterium tuberculosis (Mtb). Such a response, although extensively studied using animal models and cells from human blood, has not been characterized in cells from pulmonary hilar lymph nodes (PHLN). We characterized populations of myeloid APC from PHLN and determined their expression of CCR2, CCR5, CCR7, CD40, CD54, CD80, and CD86 as well as the cytokine/chemokine microenvironment before and after purified protein derivative (PPD) and mannosilated lipoarabinomannan (ManLAM) stimulation.

Chemokine/cytokine production by mononuclear cells from human lymphoid tissues and their modulation by Mycobacterium tuberculosis antigens.

The majority of knowledge about the role of cytokines and chemokines in controlling Mycobacterium tuberculosis infection mainly derives from animal models. In humans, this knowledge is still mainly limited to the blood compartment or accessible lymphoid organs, such as tonsils. Here, we studied cytokine and chemokine production and their modulation by M.
