Among HIV patients receiving well-organized care with free access to antiretroviral therapy, those who smoke lose more years of life to smoking than to HIV, according to a Danish study published in Clinical Infectious Diseases and available online. The findings highlight the importance of smoking cessation efforts in the long-term, integrated care of patients infected with HIV.
Marie Helleberg, MD, of Copenhagen University Hospital and colleagues estimated the effect of smoking on mortality, risk of death, and life expectancy, and the number of life years lost to smoking compared to years lost to HIV among nearly 3,000 HIV-infected patients treated in Denmark from 1995 to 2010. They also compared mortality associated with smoking between HIV patients and the country's background population. Where HIV care is integrated and antiretroviral therapy is available at no cost, "more than 60 percent of deaths among HIV patients are associated with smoking," rather than HIV, Dr. Helleberg said.
Estimated life expectancy differed significantly based on smoking status. A 35-year-old HIV patient who currently smokes had a life expectancy of 62.6 years, compared to 78.4 years for a nonsmoker infected with HIV. The loss of years of life associated with smoking was twice as high as that associated with HIV among HIV-infected patients. In addition, researchers found the excess mortality of HIV-infected smokers to be three times higher than that of individuals not infected with HIV.
"Our findings emphasize the importance of counseling HIV patients on smoking cessation as smoking may impact their life expectancy considerably more than the HIV infection itself," the study authors wrote. The results also underscore the importance of prioritizing interventions for stopping smoking in HIV patient care and for the general population. Smokers who stop see their risk of cardiovascular disease drop rather quickly, but they remain at increased risk of cancer until several years after quitting.
The emphasis on well-organized HIV care is crucial, according to Dr. Helleberg and her team. Continuing to smoke—or starting the habit—poses extra risks for patients with HIV. Patients who receive integrated care from a variety of health care professionals, including those who can help patients address lifestyle issues, can find support for decisions to stop smoking.
The study is available online. It is embargoed until 12:01 a.m. EST on Wednesday, Dec. 19, 2012:
Clinical Infectious Diseases is a leading journal in the field of infectious disease with a broad international readership. The journal publishes articles on a variety of subjects of interest to practitioners and researchers. Topics range from clinical descriptions of infections, public health, microbiology, and immunology to the prevention of infection, the evaluation of current and novel treatments, and the promotion of optimal practices for diagnosis and treatment. The journal publishes original research, editorial commentaries, review articles, and practice guidelines and is among the most highly cited journals in the field of infectious diseases. Clinical Infectious Diseases is an official publication of the Infectious Diseases Society of America (IDSA). Based in Arlington, Va., IDSA is a professional society representing nearly 10,000 physicians and scientists who specialize in infectious diseases. For more information, visit www.idsociety.org.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
