Influence of Hispanic ethnicity in prevalence of diabetes mellitus in sleep apnea and relationship to sleep phase

Recent studies have shown a strong association between insulin resistance, diabetes mellitus, and obstructive sleep apnea (OSA). This association has not been previously reported in the Hispanic population. The objective of this study was to study the prevalence of diabetes in a cohort of Hispanic patients with OSA in comparison with a white cohort. We performed a retrospective chart review of 103 Hispanic patients and 69 white patients with OSA. All patients had undergone full-night baseline polysomnography. We excluded charts of patients who underwent split-night studies and those who did not have rapid eye movement (REM) sleep. Both groups were well matched in terms of age, gender distribution, and body mass index. The prevalence of self-reported diabetes in Hispanic patients with OSA was 42.71% compared with 24.28% of whites (P = 0.005). A REM apnea hypopnea index (AHI) of > 20 was significantly associated with an increased prevalence of diabetes in the Hispanic population; this association was not seen in the white population. There was a very high prevalence of diabetes in an unselected cohort of Hispanic patients with OSA compared with white patients.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
