Here is a wake-up call. Smoking ruins productive sleep, leading to cognitive dysfunction, mood disorders, depression and anxiety.

“This study has found a common pathway whereby cigarette smoke impacts both pulmonary and neurophysiological function. Further, the results suggest the possible therapeutic value of targeting this pathway with compounds that could improve both lung and brain functions in smokers,” said Irfan Rahman, a researcher at the University of Rochester Medical Centre in Rochester, New York.

Rahman and his team found that tobacco smoke affects clock gene expression rhythms in the lung by producing parallel inflammation and depressed levels of brain locomotor activity. A similar reduction was seen in lung tissue from human smokers and patients with chronic obstructive pulmonary disease (COPD).

They placed two groups of mice in smoking chambers for short-term and long-term tobacco inhalation. One of the groups was exposed to clean air only and the other was exposed to different numbers of cigarettes during the day, said the study published in The FASEB Journal.

Researchers found that mice in smoking chambers were considerably less active following smoke exposure. (IANS)

Smoking, High BP Increases Risk of Heart Attack Recurrence

Previous studies have defined young heart attack patients as less than 45-years-old while some used a less than 40-year-old cut-off

Smoking, high BP raises risk of heart attack relapse: Study. Pixabay

Young men who are chain smokers or suffer from hypertension could be at an increased risk of heart attack recurrence, researchers have warned.

The study found that risk factors such as smoking, high blood pressure, family history of heart disease and chronic kidney disease were more prevalent among the patients who experienced a relapse.

“When treating younger patients with a history of heart attack, clinicians should emphasise better control of high blood pressure, high cholesterol and diabetes,” said Joanne Karen Recacho-Turingan, a cardiology student from The Medical City in Manila, Philippines.

“Other modifiable risk factors to highlight in patient history and address with these patients include smoking habits and obesity,” Recacho-Turingan added.

The findings were presented at the Asia Conference 2018 in Shanghai.

For the study, researchers analysed 133 young patients and found that males (90.1 per cent) with an average age of 40.9 years, experienced a second heart attack compared to females (9.9 per cent) with an average age of 39.6 years.

In addition, in these male patients, chest pain was the most common presenting symptom (81.8 per cent) while 90.9 per cent had unstable vital signs.

Heart attack in young patients can cause disability and even death at the prime of life. There are often serious consequences for these patients, their families and the health system, which can lead to an increased economic burden, according to the study.

“We must make sure to work with these patients on their modifiable risk factors to reduce their risk not just for a second heart attack, but hopefully, even preventing the first,” Recacho-Turingan noted.
