HPV vaccine prevents childhood respiratory disease

The vaccine that protects against cancer-causing types of human papillomavirus HPV also prevents an uncommon but incurable childhood respiratory disease, the chronic and difficult-to-treat condition, recurrent respiratory papillomatosis.

The condition is thought to occur in children when HPV type 6 or 11 is spread from mother to child around the time of birth. In some children, the virus can cause wart-like, non-cancerous growths called papillomas to develop in the respiratory tract, eventually making it difficult to breathe.

 The condition can be life-threatening, and repeated surgeries are usually required to keep the airway clear. Medical costs related to the disease in children. The Centers for Disease Control and Prevention CDC currently recommends two doses of the vaccine for teens younger than 15 and three doses for those who start the vaccine series at ages 15 through 26.

Recurrent respiratory papillomatosis is an uncommon but difficult-to-treat respiratory disease caused by certain types of human papillomavirus HPV. In children, the chronic disease is thought to occur when HPV is spread from mother to child around the time of birth, later causing recurring growths in the respiratory tract that usually require repeated surgeries to remove.

Exposing children to germs and pets reduces the risk of asthma

Asthma is a chronic disease that frequently aggravates and narrows the airways, leading to wheezing, coughing, breathlessness and a tight chest.

According to National Institute of Health, contact with cats, dogs, mice and cockroach at three months lowers chance of having asthma by age seven. Exposure to certain bacteria in house dust during infancy was also associated with a reduce risk.

According to a study, exposing children to pets and germs early reduces their risk of developing asthma. Exposure to allergens early in life, before asthma develops, has a preventive effect.

Early-life environment can influence the development of certain health conditions, preventing asthma before it develops is the best method of preventing it. Exposure to different indoor allergens, bacteria and bacterial products early in life may reduce the risk of developing asthma.

Researchers discovered that higher concentrations of cockroach, mouse and cat allergens present in dust samples collected from the children's homes at three months were linked to a lower risk of asthma by age seven.

How physical inactivity causes chronic diseases

Lack of exercise can raise the risk of chronic diseases like: type 2 diabetes, cancer and heart disease. New research shows that the risk of such conditions could increase with as little as 2 weeks of inactivity.

In a study of young, healthy adults, researchers found that switching from moderate-to-vigorous activity to near-sedentary behavior for just 14 days led to metabolic changes that could raise the risk of chronic disease and even premature death.

Adults between 18 and 64 years must engage in at least 150 minutes of moderate intensity activity or 75 minutes of vigorous-intensity activity every week.

Lack of regular physical activity is a key contributor to obesity. In turn, this can raise the risk of type 2 diabetes , heart disease , heart failure, and even some types of cancer. Inadeguate exercise can also hinder bone and muscle development.

The researchers enrolled 28 healthy adults with a mean age of 25 years. The adults had a mean body mass index (BMI) of 25, and they were all physically active.

For 14 days, subjects were required to participate in a step-reduction protocol, whereby they reduced their daily steps by 80 percent, to around 1,500. All participants underwent extensive health checks before and after the study, and activity trackers were worn throughout.

The 14-day step-reduction protocol led to a 125-minute reduction in daily physical activity, from 161 minutes per day to just 36 minutes. Concurrently, participants' sedentary time increased by an average of 129 minutes per day.

Reduced activity led to loss of muscle mass, increased body fat and loss of skeletal muscle mass. Total lean mass reduced by an average of 0.36 kilograms, while an average 0.21-kilogram loss was observed for leg lean mass.

Additionally, the 14-day step-reduction protocol led to an increase in total body fat. Notably, body fat was most likely to accumulate centrally, which the team notes is a significant risk factor for chronic disease.

The researchers also identified a reduction in cardiorespiratory fitness and the function of mitochondria. Lack of regular physical activity can cause obesity, heart failure and cancer.
