Air pollution linked to LCA and loss of memory: studies

(Reuters) – living in a very populous city or near a freeway with much traffic, where the air quality is bad, could generate greater chance of an accident, stroke (LCA) or memory loss, according to two us studies indicate. Both reports were published in Archives of Internal Medicine. One study reveals increased risk of LCA among residents of the Boston area after some days when the air quality was “moderate”, rather than “good”, especially when the traffic-related pollution was high. Other research, which noted thousands of women, documented a decline in long-term thinking and memory skills in those living in more polluted areas of United States faster. None of the findings could prove that pollutants were responsible for the LCA and memory problems, but previous studies supported the results of negative effects of pollution on the heart and blood vessels. “One of the important points is that at levels which are generally considered safe by the EPA (environmental protection agency) of United States we are witnessing important effects on health,” said Gregory Wellenius, of Brown University in Providence, Rhode Island, who directed the study on LCA. Wellenius team reviewed the medical records of some 1,700 patients who entered the Beth Israel Deaconess Medical Center in Boston with an LCA between 1999 and 2008. From data from a local station for control of pollution, the team found that the risk...

Public smoking bans make smoking less at home

General |

London (Reuters) – bans smoking in offices, restaurants and other public places do not lead to smokers to light more cigarettes at home, but that in fact compel them apply extra restrictions on the habit, according to a European study. Research, published on Tuesday and conducted in Great Britain, Ireland, France, Germany and Holland, revealed that a significant number of smokers also decided to prohibit smoking in their own homes after the introduction of the “smoke-free” laws public. Some restrictions on smoking in workplaces and public opponents argued that anti-smoking laws would lead to a displacement of the habit into the homes of smokers, which could increase the exposure of non-smokers–especially children–to second hand smoke. But Ute Mons of the German Cancer Research Center and the downtown cancer prevention unit of the Tobacco Control in Heidelberg – partner of the World Health Organization (who) – and whose work was published in the journal Tobacco Control, said that their findings suggested otherwise. “Our findings demonstrate that smoke-free law would stimulate smokers to complete bans smoking in their homes,” wrote the expert study. Smoking causes lung cancer, which tends to be lethal, and other chronic respiratory diseases. Is also one of the main factors of cardiovascular disease responsible for the largest number of deaths in the world. Who warned last year that tobacco would cause the death of almost 6 million...

Europe opens with success the Vega, his first ship of the 21st century

KurÃº (French Guiana), 13 feb (EFE).-the new Vega rocket, the first spacecraft that launches the European aerospace industry in the 21st century, culminated today with success its risky maiden flight in one hour and 21 minutes, faithful to the programme of the European Space Agency (ESA). The Vega, a rocket from 30 meters in height and 137 tonnes destined to place in orbit of small loads, took off at 1000 GMT from the center space European of KurÃº, in French Guiana, it reached an altitude of 1,450 kilometres above the Earth and deployed nine scientific satellites, including the Xatcobeo Spanish. “No longer any European satellite that can not be put into orbit by a European launch service”, pointed out at the end of the Mission of ESA, Jean-Jacques Dordain, director before a Chamber in which the success of a launch that represents more than nine years of work and 710 million euros of investment (US $942 million) was held without fuss. El Vega, whose reference to load is 1.5 tons transported to 700 kilometers of altitude, complete family of launchers that operates Europe and joins Ariane 5, for heavy loads, and the Russian Soyuz, which take off from KurÃº with intermediate masses since last October. The words of the exastronauta served as a final point a long hour of tension contained scientists and public suffered in silence and gave...

They note that the effects of logging can last for centuries in the forests

General |

Madrid, 13 feb ( EFE).-A team of researchers, with Spanish participation, has concluded that forest ecosystems suffer the consequences of disruption, as the logging of trees, for decades, even centuries, and that the current effects of climate change overlapped the past sequels. These are some of the findings of a study that publishes the magazine “PNAS”, which also confirms the difficulty when it comes to discern, in systems that have been subjected to shocks for a long time between the effects of the current climate change and those of past human actions. Susana Bernal, one of the authors of this work, explained to Efe that the interesting thing about the study is that it is a “effect clear” of climate change on forest ecosystems, but “not enough” to explain the changes observed. And this is the case, according to Bernal, because ecosystems have “inertia” and respond slowly to disturbances that have already suffered in the past, as the felling of trees in the early 20th century. To arrive at these conclusions, the researchers analyzed data from 50 years – climate, atmospheric deposition and export of nutrients – and forest inventory of Hubbard Brook Experimental basins, in the northeast of the us for two years. One of the analyzed variables was the change in the efficiency of inorganic nitrogen, in particular nitrate retention. According to Bernal, nitrogen is an essential...

For the first time in the country, they carried out an aortic surgery without stopping the heart

General |

at the Institute of medicine Cardiovascular of the Italian Hospital of Buenos Aires took place, for the first time in the Argentina, the replacement of aortic valve from the combination of surgical techniques and homodynamic, using the artery aorta as access. The patient, 85 years, suffered from a narrowing of the aortic valve associated with old age, and was unable to break through conventional surgery. The procedure consists in placing a valvular prosthesis through a minimum opening of the chest (surgical technique) and the direct puncture of the aortic artery, where the prosthesis is inserted and guided up to the heart (homodynamic technique). Valve replacement was carried out without the need to stop the functioning of the heart of the patient which, after 5 days of hospitalization, was given high, with an aortic working properly bioprÃ³tesis. This technique is new to our country and enables the replacement of heart valves in a way less invasive than conventional surgery and thus treat considered high-risk or non-surgical patients by age or State of health. The hybrid operating room in which it is possible to make this type of intervention is a room of homodynamic, cardiovascular imaging equipment, with everything you need to perform surgery. Currently, the replacement of heart valves can be done by conventional heart surgery through the opening of the chest, entering through the groin or neck through an...
