Cerebral Haemodynamics is altered in patients with sleep apnoea/hypopnoea syndrome

A recent study by R. Coloma Navarro and team has assessed whether patients with sleep apnoea have impaired haemodynamics when compared to contols, and to investigate a possible relationship with clinical data. The study found that daytime cerebral haemodynamics is abnormal in patients affected by sleep apnoea. Specifically, a reduction in mean blood flow velocity was seen compared to controls. Lower MFV has been related to cognitive impairment and to the severity of nocturnal hypoxia in SAHS

Hungry for sleep: A role for Endocannabinoids?

Inadequate sleep, both in quality and quantity, has been associated with increased body weight and risk of obesity. Many epidemiological studies have established this link convincingly, however, such studies cannot determine causality or the direction of effect between sleep and weight. On the one hand, increased body mass index increases the risk for obstructive sleep apnoea, and thus disturbed sleep. On the other hand, experimental sleep restriction influences processes involved in energy balance and body weight regulation.
 

Nitric Oxide and the paranasal sinuses: NO testing is an essential accompaniment to spirometry

The discovery within the paranasal sinuses for the production of nitric oxide (NO) has altered the traditional explanations of sinus physiology. The role of NO in the sinuses is likely to enhance local host defence mechanisms via direct inhibition of pathogen growth and stimulation of mucociliary activity. . Sensitive electrochemical analysers, such as FeNO, measure exhaled NO levels. It has been shown that nasal NO is altered in several airway disorders including allergic rhinitis and sinusitis.

Dear Doctors,

Welcome to the latest edition of the TSGQ E-Newsletter!
 
In this months newsletter, you will find information on:

    A 30 minute, but not a 10 minute, night-time nap is associated with sleep inertia
    Napping is an important fatigue management strategy for shift workers, especially for nightshift workers as nightshifts are synonymous with fatigue.

    Maxillomandibular volume influences the relationship between weight-loss and improvement in obstructive sleep apnoea
    A recent study published in the journal Sleep investigated the role of craniofacial skeletal size in relation to weight loss and OSA reduction

    A recent study finds that older men are at a 1.8-fold increased risk of stroke due to overnight hypoxemia
    The Journal of Thoracic Disease (2015) has estimated that 22% of men were found to have obstructive sleep apnoea (OSA); with prevalence increasing with age and obesity.

    Patient Education Combined in a Music and Habit-Forming Intervention for Adherence to Continuous Positive Airway (CPAP) Prescribed for Sleep Apnea
    As many as 50% of patients diagnosed with obstructive sleep apnoea stop adhering to the prescribed medical treatment of CPAP (Continuous Positive Airway Pressure) within one to three weeks of onset. Thus, a theory based intervention using music to support habit formation was designed to improve CPAP adherence at onset.

    Relationships between fractional exhaled nitric oxide levels and FEF25%–75% in children with asthma
    A recent study has investigated the relationship between FeNO and FEF25%–75% in children with asthma.

Sleep Medicine News

A 30 minute, but not a 10 minute, night-time nap is associated with sleep inertia
Night shifts are associated with increased sleepiness, performance impairment, and risk of workplace injury and errors. Studies have shown 30 minute naps cause sleep inertia lasting between 5-35 minutes and that 10 min naps immediately improve performance, with this improvement lasting at least 35min after waking. While the methodology and operational settings of nap related research is quite varied across the industry, most studies have observed benefits to performance and subjective alertness following naps during nightshift.


Maxillomandibular volume influences the relationship between weight-loss and improvement in obstructive sleep apnoea
The effectiveness of weight loss as a treatment for OSA is variable and identification of patient factors which relate to weight loss therapy responsiveness is of clinical use. A recent study published in the journal Sleep investigated the role of craniofacial skeletal size in relation to weight loss and OSA reduction. The findings suggest that those with smaller maxillary-mandibular dimensions have greatest benefit from weight loss. Reduced craniofacial dimensions could represent a phenotype of OSA patients most suitable for weight loss therapy.

A recent study finds that older men are at a 1.8-fold increased risk of stroke due to overnight hypoxemia
Nocturnal hypoxemia (independent of resting saturation levels and COPD) is associated incident stroke, and strongly predicts incident fatal stroke among older men. Hypoxemia during sleep may represent a more sensitive indicator for severity of SDB among older adults relative to the traditional count-based indices of SDB. Treatment of SDB in older men may prove effective in reducing the risk of stroke, and preventing unnecessary death from stroke.

Patient Education Combined in a Music and Habit-Forming Intervention for Adherence to Continuous Positive Airway (CPAP) Prescribed for Sleep Apnea
The investigation was based on The Triandis Theory of Behaviour tenet is that adherence at onset of treatment emerges from knowledge of the consequences of non-adherence and from practicing repeated health treatment behaviours which then become habitual. Researchers using Triandis Theory have empirically-verified that following routines which guide treatment use and sensitizes patients to benefits and non-treatment risks result in adherence. Thus, it follows that an intervention which informs patients about CPAP benefits, consequences of non-adherence and guides a habitual routine of relaxation and nightly CPAP use with soothing music would result in adherence.

Relationships between fractional exhaled nitric oxide levels and FEF25%–75% in children with asthma
FeNO levels were higher in group of asthmatic children with impaired FEF25%–75% level. FeNO levels were inversely correlated with FEF25%–75% only in impaired small-airway obstruction group after adjustment for atopy. These results suggest that small-airway obstruction may relate more closely to airway inflammation in asthmatic children with impaired small-airway function.
