Preschoolers have the highest rate of emergency visits and hospitalisations for asthma exacerbations of all age groups, with most triggered by upper respiratory tract infections (URTIs) and occurring in the fall or winter. Vitamin D insufficiency is highly prevalent in Canadian preschoolers with recurrent asthma exacerbations, particularly in winter. It is associated with more URTIs and, in patients with asthma, more oral corticosteroid (OCS) use. Although evidence suggests that vitamin D supplements significantly decrease URTIs and asthma exacerbations requiring OCS, there is insufficient data in preschoolers. This study aims to determine the impact of vitamin D supplementation on exacerbations requiring OCS, in preschoolers with recurrent URTI-induced asthma exacerbations.

Patients with respiratory diseases such as cystic fibrosis, chronic obstructive pulmonary disease, or asthma often experience an acute worsening of respiratory symptoms, termed exacerbations. Although...
Children with asthma may have a disease course with or without exacerbations, but the relationship between exacerbations and lung function development is poorly understood.
Asthma exacerbations are a significant cause of health care use and mortality. Home management strategies may be effective in managing many exacerbations before presentation to a health care instituti...

To investigate whether intrauterine exposure to maternal asthma or asthma exacerbations increases the risk of attention-deficit/hyperactivity disorder (ADHD).
In this 7-month randomized controlled trial, children aged 1 to less than 6 years, with recurrent asthma attacks triggered mostly by colds, will receive a high dose of vitamin D or a place...
The study aim is in two phases. First phase: to evaluate the influence of vitamin D deficiency on asthma severity, degree of airway obstruction and frequency of asthma exacerbations. Secon...
This study will determine whether vitamin D3 prevents severe asthma attacks in children who have a serum vitamin D (25(OH)D) level
Viral infections are the main cause of asthma attacks in preschoolers, an age group with the highest rate of emergency visits due to asthma. While high doses of inhaled or oral corticoster...
We hypothesize the herbal preparation will enhance the preschoolers' immune response and when taken prophylactically for 12 weeks will decrease episodes of upper respiratory infections and...
The prevention of recurrences or exacerbations of a disease that already has been diagnosed. This also includes prevention of complications or after-effects of a drug or surgical procedure.
A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.
A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)
OXIDOREDUCTASES which mediate vitamin K metabolism by converting inactive vitamin K 2,3-epoxide to active vitamin K.
Specific practices for the prevention of disease or mental disorders in susceptible individuals or populations. These include HEALTH PROMOTION, including mental health; protective procedures, such as COMMUNICABLE DISEASE CONTROL; and monitoring and regulation of ENVIRONMENTAL POLLUTANTS. Primary prevention is to be distinguished from SECONDARY PREVENTION and TERTIARY PREVENTION.
