While studies have repeatedly linked maternal smoking during pregnancy with reduced sperm count in male children, a new research showed that men whose fathers smoked at the time of pregnancy also had 50 per cent lower count of sperms than those with non-smoking fathers.

The findings showed that, independently of nicotine exposure from the mother, socioeconomic factors, and their own smoking, men with fathers who smoked had a 41 per cent lower sperm concentration and 51 per cent fewer sperm count than those with non-smoking fathers.

“I was very surprised that regardless of the mother’s level of exposure to nicotine, the sperm count of men whose fathers smoked was so much lower,” said Jonatan Axelsson, specialist physician at Lund University in Sweden. “We know there is a link between sperm count and chances of pregnancy, so that could affect the possibility for these men to have children in future.

“The father’s smoking is also linked to a shorter reproductive lifespan in daughters, so the notion that everything depends on whether the mother smokes or not doesn’t seem convincing,” he added.

However, the research has not determined the underlying mechanisms behind this. But, similar studies have shown links between smoking fathers and various health outcomes in children, such as malformations, Axelsson noted.

It could be because most newly occurring mutations (known as de novo mutations) come via the father and there are also links between the father’s age and a number of complex diseases, said researchers in the paper published in the journal PLOS ONE.

In addition, researchers have observed that smoking is linked to DNA damage in sperm and that smokers have more breaks in the DNA strand. Children of fathers who smoke have been reported to have up to four times as many mutations in a certain repetitive part of the DNA as children of non-smoking fathers.

“Unlike the maternal ovum, the father’s gametes divide continuously throughout life and mutations often occur at the precise moment of cell division.

“We know that tobacco smoke contains many substances that cause mutations so one can imagine that, at the time of conception, the gametes have undergone mutations and thereby pass on genes that result in reduced sperm quality in the male offspring,” Axelsson said. The study was conducted on 104 Swedish men aged between 17 and 20 years.  (IANS)

Here’s a List of Asthma Triggers for Patients

Know your asthma triggers

A patient of asthma should try to identify these triggers and always avoid them to keep the asthma under control, states Dr Goel. Pixabay

Asthma is a disease of airflow obstruction caused by an inflammation of the bronchi in individuals who have hypersensitive airways.

Dr. Manoj Goel, Director & Head, Pulmonology, Pulmonary Critical Care & Sleep Medicine, Fortis Memorial Research Institute, Gurugram talks about extrinsic factors called triggers.

“Hypersensitivity in airways is due to a variety of intrinsic factors. But there are several extrinsic factors which stimulate this hypersensitivity precipitating the attacks of bronchial asthma or may contribute to the persistence of symptoms. A patient of asthma should try to identify these triggers and always avoid them to keep the asthma under control, states Dr Goel.

Adding, “However, there are many triggers which may are not avoidable like pollens in the atmosphere. Therefore, patients of asthma should continue their preventive inhalers as per the advice of the doctors. There could be numerous triggers depending upon the home and workplace environments which a patient can identify himself.”

Some triggers include:

Tobacco smoke generates oxidative stress and proinflammatory effects on the lungs which in turn increases airway obstruction and accelerates the normal annual decline in lung function. Even secondhand smoke, that is generated can trigger asthma. Smoking can also lead to development of COPD which is a progressive irreversible obstructive airway disease.

Air pollution due to traffic and uncontrolled industrialisation is another important trigger.

Indoor air pollutants like paints, adhesives, flooring chemicals, cleaning products, combustion products from cooking and heater, mosquito coils do contribute in triggering asthma.

House dust mites, which are tiny bugs found in every corner of each home is important trigger for chronic persistent asthma. To cut their exposure, avoid carpets and soft toys at home, wash your pillow covers and bed linens with warm water regularly.

Psychosocial factors such as stress, anxiety, childhood adverse events, depression do contribute as risk factors for asthma.

Some people have mold allergies. Therefore, look for any fungus in the house and repair damp areas in the house.
Cleaning of air conditioners and coolers is required time to time.

Viral infections linked to influenza; respiratory syncytial virus can trigger asthma.

Asthma patients stress

Obesity has shown to increase the risk of uncontrolled asthma. Obesity has been associated with low grade inflammation and the resultant oxidative stress. Studies have shown that weight loss has been associated with significant improvement in asthma control and higher symptomatic remission rate.

Patients suffering from rhinitis and rhinosinusitis are more liable to have asthma supporting unified airway concept. Certain drugs like beta-blockers, aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, may trigger symptoms in some people with asthma.

Lastly asthmatic patients should avoid strong smells like perfumes, cold food and beverages and smoke of any kind even during prayers and aartis.(IANS)

Study Reveals Exposure To E-Cigarette Vape Is Unsafe For Children

Although e-cigarettes, found comparatively safer than cigarettes in terms of harmful substances released, may prove no less harmful when used in the presence of children or inside homes and cars.

Believing that exposure to e-cigarette vape is safe for children, parents are increasingly vaping both at home and in car, finds a study.

The study showed only 38 per cent of parents who smoked cigarettes and 22 per cent dual users were found to strictly restrict cigarette use in both home and car.

On the other hand, 56 per cent of both e-cigarette users and dual users reported using e-cigarettes in their cars with children around. The research included 750 parents.

“The finding that a large majority of parents are vaping e-cigarettes inside homes and cars is an alarming trend,” said lead author Jeremy Drehmer at the Massachusetts General Hospital in the US.

“Our results suggest parents perceive it’s safe to use electronic cigarettes and are not taking the same precautions they do to protect their children from exposure to traditional cigarettes,” Drehmer said.

Carcinogenetic volatile organic compounds have been detected in the urine of e-cigarette users, and e-cigarettes leave deposits of nicotine on surfaces when used inside, according to the paper published in the Pediatrics journal.

Drehmer said parents have been misled by the marketing of vaping products to believe that the aerosol produced by them is harmless to children.

The researchers said tobacco majors market e-cigarettes as healthy products without warning about the harms to infants and children from nicotine and ultra-fine toxic particles that spread into the air and coats surfaces.

“Paediatric healthcare providers need to help set the record straight and inform parents that e-cigarette vapour is not safe for children,” Drehmer suggested. (IANS)

Fathers Experience More Happiness Than Mothers in Their Parenthood, Says Study

"Fathers may fare better than mothers in part due to how they spend their time with their children," said Katherine Nelson-Coffey, Assistant Professor at the Sewanee, The University of the South in the US

Fathers experience more well-being and satisfaction than mothers in their parenthood and even when interacting with their children, a new study suggests.

Researchers from the University of California in the US analysed three separate studies consisting of 18,000 people that looked at the scale of happiness, psychological satisfaction, depressive symptoms and stress among others.

The first two studies compared the well-being of parents with that of people who do not have children.

The findings published in the journal “Personality and Social Psychology Bulletin”, showed that fathers reported greater satisfaction with their lives and feelings of connectedness to others.

They also reported greater positive emotions and fewer daily hassles than mothers, or relatives or peers without children.

They even showed fewer depressive symptoms than men without children, whereas mothers reported more depressive symptoms than women who do not have children.

The third study considered parenthood and well-being while engaging in childcare or interacting with children compared to other daily activities.

Men were found to be happier while caring for their children than women suggesting that gender significantly impacted the association between childcare and happiness.

In terms of daily interactions also men reported greater happiness.

One possible explanation given said fathers were more likely to indicate they were playing with their children while they were caring for them or interacting with them as compared to the mothers.
