(Press-News.org) Munich, Germany: A baby has a greater risk of asthma if his or her father smoked prior to conception.
The research, presented at the European Respiratory Society (ERS) International Congress in Munich today (08 September 2014), is the first study in humans to analyse the link between a father's smoking habits before conception and a child's asthma. The findings add to growing evidence from animal studies which suggest that the father's exposures before parenthood can harm his child.
The study analysed the smoking habits of over 13,000 men and women via a questionnaire. The researchers analysed the link in both mothers and fathers and looked at the number of years a person had smoked prior to conception, the incidence of asthma in children and whether the parent had quit before the baby was conceived.
The results showed that non-allergic asthma (without hayfever) was significantly more common in children with a father who smoked prior to conception. This risk of asthma increased if a father smoked before the age of 15 and this risk grew the longer the duration of smoking. The researchers observed no link between the mother's smoking prior to conception and a child's asthma.
Dr Cecile Svanes, from the University of Bergen, Norway, said: "This study is important as it is the first study looking at how a father's smoking habit pre-conception can affect the respiratory health of his children. Given these results, we can presume that exposure to any type of air pollution, from occupational exposures to chemical exposures, could also have an effect. It is important for policymakers to focus on interventions targeting young men and warning them of the dangers of smoking and other exposures to their unborn children in the future."

Input from a psychologist can help improve asthma symptoms
2014-09-08
Munich, Germany: Psychological input into the treatment and management of people with severe asthma can help improve their symptoms, according to a new study.
People with severe asthma often experience symptoms that are difficult to treat. There is current debate in the healthcare community about the best way to treat these people. Around 27% of people with severe asthma are thought to experience psychological problems'; however, this isn't routinely addressed by asthma healthcare professionals.

Breath temperature test could identify lung cancer
2014-09-08
Munich, Germany: The temperature of exhaled breath could be used to diagnose lung cancer, according to a new study.
The research, presented at the European Respiratory Society (ERS) International Congress in Munich today (8 September 2013), suggests that testing the temperature of breath could be a simple and noninvasive method to either confirm or reject the presence of lung cancer.
Many research teams have been looking at the possibility of using breath tests for a number of cancers. This is the first study looking at breath temperature as a marker in lung cancer. ...
Many patients in cancer centers may not experience a dignified death
2014-09-08
A new study that surveyed physicians and nurses in hospitals within cancer centers in Germany suggests that many patients there do not experience a dignified death. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the study indicates the need for cancer centers to invest more in palliative care services, adequate rooms for dying patients, staff training in end-of-life care, and advance-care-planning standards.
Previous research has shown that hospitals are often ill-prepared to provide care for dying patients. To investigate whether ...
Global food trade may not meet all future demand, University of Virginia study indicates
2014-09-08
As the world population continues to grow, by about 1 billion people every 12 to 14 years since the 1960s, the global food supply may not meet escalating demand – particularly for agriculturally poor countries in arid to semi-arid regions, such as Africa's Sahel, that already depend on imports for much of their food supply.
A new University of Virginia study, published online in the American Geophysical Union journal, Earth's Future, examines global food security and the patterns of food trade that – until this analysis – have been minimally studied.

Taking short walking breaks found to reverse negative effects of prolonged sitting
2014-09-08
BLOOMINGTON, Ind. -- An Indiana University study has found that three easy -- one could even say slow -- 5-minute walks can reverse harm caused to leg arteries during three hours of prolonged sitting.
Sitting for long periods of time, like many people do daily at their jobs, is associated with risk factors such as higher cholesterol levels and greater waist circumference that can lead to cardiovascular and metabolic disease. When people sit, slack muscles do not contract to effectively pump blood to the heart. Blood can pool in the legs and affect the endothelial ...
Sleeping on animal fur in infancy found to reduce risk of asthma
2014-09-08
Munich, Germany: Sleeping on animal fur in the first three months of life might reduce the risk of asthma in later childhood a new study has found.
The new research, presented at the European Respiratory Society (ERS) International Congress in Munich today (8 September 2014), suggests that exposure to the microbial environment in animal skin and fur could have a protective effect against asthma and allergies.
Previous studies have suggested that exposure to a wider range of environments fromyoung age could be protective against asthma and allergies. These findings ...
The Lancet HIV: High rates of recreational drug use among HIV-positive gay and bisexual men in the UK strongly linked with condomless sex
2014-09-08
New research published in The Lancet HIV shows that polydrug use is common among HIV-positive men who have sex with men (MSM) [1] and is strongly linked to sex without a condom (condomless sex).
This is the largest questionnaire study of people living with HIV in the UK, accounting for about 5% of all HIV-diagnosed MSM in the UK. The findings show that half of MSM surveyed had used recreational drugs at least once in the previous 3 months [2]. About half of those who used drugs took three or more different types of drugs, while roughly a fifth said they had used five ...
The Lancet Respiratory Medicine: Benralizumab for chronic obstructive pulmonary disease and sputum eosinophilia
2014-09-08
Chronic obstructive pulmonary disease (COPD) is associated with eosinophilic airway inflammation in 10–20% of patients. Benralizumab, a monoclonal antibody, has been shown to decrease the number of blood and sputum eosinophils. In this trial of 101 patients with COPD whether benralizumab reduces the number of acute exacerbations was investigated. Benralizumab was found to be no more effective at preventing acute COPD exacerbations than placebo overall. However, the authors conclude that subgroup analyses suggest more research into the use of benralizumab in patients with ...
Dynamic duo takes out the cellular trash
2014-09-07
LA JOLLA—In most of the tissues of the body, specialized immune cells are entrusted with the task of engulfing the billions of dead cells that are generated every day. When these garbage disposals don't do their job, dead cells and their waste products rapidly pile up, destroying healthy tissue and leading to autoimmune diseases such as lupus and rheumatoid arthritis.
Now, Salk scientists have discovered how two critical receptors on these garbage-eating cells identify and engulf dead cells in very different environments, as detailed today in Nature Immunology.
"To ...
Platelet-like particles augment natural blood clotting for treating trauma
2014-09-07
A new class of synthetic platelet-like particles could augment natural blood clotting for the emergency treatment of traumatic injuries – and potentially offer doctors a new option for curbing surgical bleeding and addressing certain blood clotting disorders without the need for transfusions of natural platelets.
The clotting particles, which are based on soft and deformable hydrogel materials, are triggered by the same factor that initiates the body's own clotting processes. Testing done in animal models and in a simulated circulatory system suggest that the particles ...
