Macarthur K, Bradley T, Ryan C, Alshaer H
Am J Otolaryngol . 2019 Sep; 41(1):102283. PMID: 31526628
Background: The impact of simple snoring on sleep structure and sleepiness has not been well described. In several studies, self-reported snoring was associated with increased daytime sleepiness. However, most studies...

Carvalho C, Bresler R, Zhi Y, Alshaer H, Granton J, Ryan C
Heliyon . 2019 Jul; 5(7):e02034. PMID: 31317084
Objectives: Our aims were to evaluate HRV in pulmonary hypertension (WHO Group 1 and 4) compared to control subjects, and to assess whether the presence of sleep apnea in those...

Inami T, Kasai T, Yumino D, Perger E, Alshaer H, Hummel R, et al.
Sleep . 2019 Apr; 42(4). PMID: 30946471
Study Objectives: In patients with heart failure (HF) and reduced left ventricular ejection fraction (HFrEF), stroke volume (SV) falls during hyperpnea of Cheyne-Stokes respiration with central sleep apnea (CSR-CSA). We...

Vena D, Lyons O, Fernie G, Popovic M, Malta D, Alshaer H, et al.
Sleep Med . 2019 Mar; 57:36-42. PMID: 30897454
Study Objectives: Overnight fluid shift from the legs into the neck may contribute to the pathogenesis of snoring and obstructive sleep apnea (OSA). The present study investigates the effects of...

Alshaer H, Hummel R, Mendelson M, Marshal T, Bradley T
J Clin Sleep Med . 2019 Mar; 15(3):463-470. PMID: 30853041
Study Objectives: Snoring is perceived to be directly proportional to sleep apnea severity, especially obstructive sleep apnea (OSA), but this notion has not been thoroughly and objectively evaluated, despite its...

Wu R, Liaqat D, de Lara E, Son T, Rudzicz F, Alshaer H, et al.
JMIR Mhealth Uhealth . 2018 Jun; 6(6):e10046. PMID: 29903700
Background: Acute exacerbations of chronic obstructive pulmonary disease (COPD) are associated with accelerated decline in lung function, diminished quality of life, and higher mortality. Proactively monitoring patients for early signs...

Alshaer H, Ryan C, Fernie G, Bradley T
Sleep Sci . 2018 May; 11(1):28-33. PMID: 29796198
Background: Attended polysomnography (PSG) is the standard diagnostic test for sleep apnea (SA). However, due to internight variability in SA, a single night PSG may not accurately reflect the true...

Alshaer H, Pandya A, Zivanovic I, Carvalho C, Ryan C
Respir Physiol Neurobiol . 2018 Jan; 249:62-68. PMID: 29329819
Objectives: To evaluate if treatment with continuous positive airway pressure (CPAP) compared to usual care in stroke patients with obstructive sleep apnea (OSA) over one month reduces delta and alpha...

Perger E, Inami T, Lyons O, Alshaer H, Smith S, Floras J, et al.
J Clin Sleep Med . 2017 Oct; 13(11):1235-1241. PMID: 29065956
Study Objectives: In heart failure (HF), we observed two patterns of hyperpnea during Cheyne-Stokes respiration with central sleep apnea (CSR-CSA): a positive pattern where end-expiratory lung volume remains at or...

Zhu K, Bradley T, Patel M, Alshaer H
Sleep Breath . 2017 Jun; 21(4):821-828. PMID: 28608295
Objective: Supine body orientation plays an important role in precipitating upper airway collapse in a significant proportion of obstructive sleep apnea (OSA) patients known to have supine-predominant OSA (OSAsup). Traditionally,...
