ABSTRACT

Air pollution is growing fastest in monsoon-affected South Asia. During the dry winter monsoon, the fumes disperse toward the Indian Ocean, creating a vast pollution haze, but their fate during the wet summer monsoon has been unclear. We performed atmospheric chemistry measurements by aircraft in the Oxidation Mechanism Observations campaign, sampling the summer monsoon outflow in the upper troposphere between the Mediterranean and the Indian Ocean. The measurements, supported by model calculations, show that the monsoon sustains a remarkably efficient cleansing mechanism by which contaminants are rapidly oxidized and deposited to Earth's surface. However, some pollutants are lofted above the monsoon clouds and chemically processed in a reactive reservoir before being redistributed globally, including to the stratosphere.

ABSTRACT

With its increasing incidence, diabetes is one of the major challenges of the 21th century. Against this background, the Bavarian State Ministry of Public Health and Care Services (BStMGP) started in 2014 the campaign "Diabetes moves us!". The scientific institute for prevention in health care (WIPIG) supported the activities of Bavarian pharmacies and evaluated the extent to which they might be able to contribute towards prevention. Besides additional training of pharmaceutical staff, WIPIG initiated a diabetes prevention network. Pharmacies that were members of the network had the opportunity to order a campaign package including an evaluation questionnaire and to register their activity in the calendar of events of the campaign. A total of 215 pharmacies signed up for the diabetes prevention network and registered 103 events. The WIPIG received 67 completed evaluation questionnaires. Most often (86.6%) the pharmacies conducted a blood glucose screening; 76.1% carried out screening with the diabetes risk questionnaire FINDRISC of the German Diabetes Foundation and 22.4% gave a information lecture on diabetes. During the screening 2,502 persons had their blood sugar checked and 1,765 persons filled in the FINDRISC questionnaire. Overall, 190 persons were advised to visit their physician because of a very high blood glucose level. On the basis of the FINDRISC, 80.2% were advised to change their lifestyle to prevent type 2 diabetes.

ABSTRACT

To mitigate the diesel particle pollution problem, diesel vehicles are fitted with modern exhaust after-treatment systems (ATS), which efficiently remove engine-generated primary particles (soot and ash) and gaseous hydrocarbons. Unfortunately, ATS can promote formation of low-vapor-pressure gases, which may undergo nucleation and condensation leading to formation of nucleation particles (NUP). The chemical nature and formation mechanism of these particles are only poorly explored. Using a novel mass spectrometric method, online measurements of low-vapor-pressure gases were performed for exhaust of a modern heavy-duty diesel engine operated with modern ATS and combusting low and ultralow sulfur fuels and also biofuel. It was observed that the gaseous sulfuric acid (GSA) concentration varied strongly, although engine operation was stable. However, the exhaust GSA was observed to be affected by fuel sulfur level, exhaust after-treatment, and driving conditions. Significant GSA concentrations were measured also when biofuel was used, indicating that GSA can be originated also from lubricant oil sulfur. Furthermore, accompanying NUP measurements and NUP model simulations were performed. We found that the exhaust GSA promotes NUP formation, but also organic (acidic) precursor gases can have a role. The model results indicate that that the measured GSA concentration alone is not high enough to grow the particles to the detected sizes.

ABSTRACT

The Mediterranean Intensive Oxidant Study, performed in the summer of 2001, uncovered air pollution layers from the surface to an altitude of 15 kilometers. In the boundary layer, air pollution standards are exceeded throughout the region, caused by West and East European pollution from the north. Aerosol particles also reduce solar radiation penetration to the surface, which can suppress precipitation. In the middle troposphere, Asian and to a lesser extent North American pollution is transported from the west. Additional Asian pollution from the east, transported from the monsoon in the upper troposphere, crosses the Mediterranean tropopause, which pollutes the lower stratosphere at middle latitudes.

ABSTRACT

Description of the first case of angio-immunoblastic lymphadenopathy with dysproteinemia diagnosed in a male patient 64 years old and which preceded the development of a lymphoma. The importance of this study is the association that may exist between certain drugs and the development of angioimmunoblastic lymphadenopathy, which occurred in our patient with the use of diphenylhydantoin. This disease can present itself up to 22 years after exposure to the agent.

ABSTRACT

The Authors describe the clinical histories of two patients who presented with the infrequent delusion of being infected with very tiny organisms which crawl in the skin (Ekbom's syndrome) and comments on its phenomenological characteristics and nosological classification. In their discussion they clarify aspects of the pathogenesis of delusions in this condition.
