Changes in pharyngeal anatomy and apnea/hypopnea index after a mandibular advancement device.

Objectives: This study aimed to evaluate the therapeutic effcacy of custom-made mandibular advancement devices (MAD) in the control of primary snoring and sleep apnea and to correlate with anatomical changes identified through imaging tests.

Methods: Patients (n = 17) diagnosed with sleep apnea or primary snoring were included in this study and subsequently treated with MADs. Changes were assessed using a polysomnographic study (PSG), the Epworth Sleepiness Scale (ESS), and an imaging study with computed tomography scanning (CT).

Cognitive behavioral therapy for insomnia helps to reverse cognitive impairment in insomnia patients.

Introduction: Insomnia is the most common of sleep disorders, it induces a wide variety of organic symptoms, including somatic and cognitive impairments. There are pharmacological drugs nowadays that help diminish sleep impairments due to insomnia. However, most of them seem to be worsening cognitive impairments, benzodiazepine receptor agonists, in particular, seem to induce an even worst deterioration of cognitive function.

Plasma Levels of Amyloid-β Peptides and Tau Protein in Mexican Patients with Alzheimer's Disease.

Background: Alzheimer's disease (AD) causes memory deficit and alterations in other cognitive functions, mainly in adults over 60 years of age. As the diagnosis confirmation is performed by a postmortem neuropathological examination of the brain, this disease can be confused with other types of dementia at early stages. About 860,000 Mexicans are affected by dementia, most of them with insufficient access to adequate comprehensive health care services.

Sleep and Mental Health Disturbances Due to Social Isolation during the COVID-19 Pandemic in Mexico.

The coronavirus disease (COVID-19) that broke out in China in December 2019 rapidly became a worldwide pandemic. In Mexico, the conditions requiring the declaration of a sanitary emergency were reached by the last week of March 2020, and health authorities' limited mobility and imposed social isolation were the main strategies to keep the virus from spreading. Thus, daily living conditions changed drastically in a few days, generating a stressful situation characterized by an almost complete lack of mobility, social isolation, and forced full-time interactions with family members.

Reduced systemic levels of IL-10 are associated with the severity of obstructive sleep apnea and insulin resistance in morbidly obese humans.

Obstructive sleep apnea (OSA) has been related to elevation of inflammatory cytokines and development of insulin resistance in morbidly obese (MO) subjects. However, it is still unclear whether the systemic concentration of anti-inflammatory mediators is also affected in MO subjects directly related to the severity of OSA and level of insulin resistance. Normal weight and MO subjects were subjected to overnight polysomnography in order to establish the severity of OSA, according to the apnea-hypopnea index (AHI).

Sleep-EEG patterns of school children suffering from symptoms of depression compared to healthy controls.

Depression in children is often an elusive disorder and its diagnostic tools are a matter of controversy. Several scales have been developed in an attempt to specifically detect some of the major aspects of depression, i.e.
