We’ve been in search of a less-invasive method to achieve the same goal of lung decrease, without the risks inherent in surgery, says Tag Dransfield, M.D., associate professor in the division of Pulmonary, Essential and Allergy Care Medication and primary investigator in the new study. The AeriSeal Program treatment is performed with a standard bronchoscopy, when a bronchoscope is used to thread a catheter through the affected person's airway to the most diseased regions of the lung.Depressed people with these symptoms are at least 50 % more likely to attempt suicide, the new study found. Assessing these symptoms in every depressed individual we see is really important, and offers immense therapeutical implications, study lead writer Dr. Dina Popovic, of the Hospital Clinic de Barcelona, in Spain, said in a news launch from the European University of Neuropsychopharmacology . The findings were scheduled for presentation Saturday at the ECNP’s annual conference in Amsterdam. One expert in the usa concurred with the findings.
