Asthma and pollution: what we need to know

The study: Impact of Air Pollution on Asthma Outcomes, published on the International journal of environmental research and public health, deals with a very important aspect of health, which is undergoing changes with the pollution that is causing a real disaster ecological across the world.

Causing continuous global warming, melting ice, destruction of forests and biobalances and devastating weather events. But also putting our health at risk, especially with air, water and soil pollution. In the study we can read: "Asthma is a chronic respiratory disease characterized by variable airflow obstruction, bronchial hyperresponsiveness, and airway inflammation.

Evidence suggests that air pollution has a negative impact on asthma outcomes in both adult and pediatric populations.

Asthma and pollution: what we need to know

The aim of this review is to summarize the current knowledge on the effect of various outdoor and indoor pollutants on asthma outcomes, their burden on its management, as well as to highlight the measures that could result in improved asthma outcomes.

Traffic-related air pollution, nitrogen dioxide and second-hand smoking (SHS) exposures represent significant risk factors for asthma development in children. Nevertheless, a causal relation between air pollution and development of adult asthma is not clearly established.

Exposure to outdoor pollutants can induce asthma symptoms, exacerbations and decreases in lung function. Active tobacco smoking is associated with poorer asthma control, while exposure t o SHS increases the risk of asthma exacerbations, respiratory symptoms and healthcare utilization.

Other indoor pollutants such as heating sources and molds can also negatively impact the course of asthma. Global measures, that aim to reduce exposure to air pollutants, are highly needed in order to improve the outcomes and management of adult and pediatric asthma in addition to the existing guidelines."

The Mediterranean diet and its relationship with migraines

The study: Associations between diet quality, DASH and Mediterranean dietary patterns and migraine characteristics, published on the Nutritional neuroscience, makes an interesting retrospective on a problem that afflicts millions of people across the globe.

In this case, it deals with a specific topic, the Mediterranean diet, and its relationship with migraines. The quality of the diet is an extremely important topic for our health, and in recent years we have seen how the worldwide awareness of this topic is sensitizing millions of people.

In the study we can read: "This study was conducted to describe the dietary patterns and diet quality and to examine the correlation between diet quality, dietary patterns (Mediterranean or DASH) and migraine attributes.

Individuals between the ages of 18-64 who applied to the headache outpatient clinic and were diagnosed with episodic migraine were evaluated by a neurologist. Healthy Eating Index-2010 was used to determine the diet quality.

Dietary Approaches to Stop Hypertension compliance scale and Mediterranean Diet Adherence Screener were used to describe the dietary patterns. It was found that individuals with a low Mediterranean Diet Adherence Screener score had more severe disability and more severe and frequent attacks (p <0.05).

In addition, a significant negative correlation was found between Mediterranean Diet Adherence Screener score and attack severity (r = -0.733, p <0.05). Individuals with a low Dietary Approaches to Stop Hypertension compliance scale score had more severe and frequent attacks (p <0.05).

There was a significant negative correlation between attack severity and Dietary Approaches to Stop Hypertension compliance scale scores (r = -0.700, p <0.001). Individuals with poor diet quality had more severe migraine attacks compared to others (p <0.05).

A significant negative correlation was found between diet quality total score and attack severity (r = 0.458, p <0.05). High diet quality scores and higher vegetables, fruits, legumes, and oil seeds subscores, DASH and Mediterranean dietary patterns were associated with lower migraine attack severity (p <0.05).

A nutritional approach that adopts the Mediterranean diet or involves a good diet quality pattern can help alleviate the symptoms of individuals with migraine. "
