Cut-off points of neck and waist circumference as predictors of obstructive sleep apnea in the Colombian population: a comparison with polysomnography.

Background: Neck circumference (NC) is a useful anthropometric measure for predicting obstructive sleep apnea (OSA). Ethnicity and sex also influence obesity phenotypes. NC cut-offs for defining OSA have not been established for the Latin American population.

Sleep Quality, Insomnia, and Perceived Stress among Colombian Healthcare Workers during the COVID-19 Pandemic.

 The COVID-19 pandemic has imposed a great burden on healthcare workers worldwide. The aim of the present study was to assess sleep quality, insomnia, and perceived stress in healthcare workers of a high complexity hospital located in Bogota, Colombia.  Cross-sectional study in which 1,155 healthcare workers at the Hospital Universitario San Ignacio in Bogotá, Colombia were included, between September and October 2020.

Biomarkers for the severity of periodontal disease in patients with obstructive sleep apnea:IL-1 β, IL-6, IL-17A, and IL-33.

Objective: This study aims to compare the salivary and gingival crevicular fluid (GCF) concentrations of five cytokines: IL-1β, IL-6, IL-17A, IL-33, and Tumor Necrosis Factor-alpha (TNF-α) in patients with OSA and their association with periodontitis.

Methods: Samples of saliva and GCF were obtained from 84 patients classified into four groups according to periodontal and OSA diagnosis: G1(H) healthy patients, G2(P) periodontitis and non-OSA patients, G3(OSA) OSA and non-periodontitis patients, and G4(P-OSA) periodontitis and OSA patients. The cytokines in the samples were quantified using multiplexed bead immunoassays.

Patients with obstructive sleep apnea can favor the predisposing factors of periodontitis by the presence of and , increasing the severity of the periodontal disease.

Objective: The aim of this study was to analyze the cultivable oral microbiota of patients with obstructive sleep apnea (OSA) and its association with the periodontal condition.

Methods: The epidemiology profile of patients and their clinical oral characteristics were determined. The microbiota was collected from saliva, subgingival plaque, and gingival sulcus of 93 patients classified into four groups according to the periodontal and clinical diagnosis: Group 1 ( = 25), healthy patients; Group 2 ( = 17), patients with periodontitis and without OSA; Group 3 ( = 19), patients with OSA and without periodontitis; and Group 4 ( = 32), patients with periodontitis and OSA.

Prevalence of sleep apnea in children and adolescents in Colombia according to the national health registry 2017-2021.

Objective: To describe the sociodemographic and epidemiological characteristics of diagnosis and treatment of pediatric patients with sleep apnea, both central and obstructive, in Colombia between 2017 and 2021.

Methods: Observational, descriptive, cross-sectional, epidemiological study using the International Classification of Diseases and Related Health Problems as search terms for sleep apnea, based on SISPRO, the Colombian national health registry. Stratification by gender and age groups was performed.

Sleep problems in low income, urban pediatric populations living at different altitudes in Colombia.

Objective: To determine the frequency of sleep problems in low-income, urban pediatric populations in cities at different altitudes in Colombia.

Methods: A descriptive, cross-sectional population-based observational study was conducted in children aged between 2 and 12 years in the low income, urban areas of three cities in Colombia (Santa Marta, Bucaramanga, and Bogotá) located at 15, 959, and 2640 m above sea level, respectively. Sociodemographic data were collected, and the Spanish version of the Pediatric Sleep Questionnaire was used.

Sensitivity and specificity of four screening sleep-disordered breathing tests in patients with and without cardiovascular disease.

Objectives: Polysomnogram is the gold standard for the diagnosis of sleep-disordered breathing (SDB); a sensitive and specific alternative strategy would be ideal, due to its low availability, and screening patients at high risk of OSA is very important. This study aimed to determine the operating characteristics of screening tests in patients with and without cardiovascular disease (CVD).

Material And Methods: Epworth sleepiness scale (ESS), Berlin, STOP-bang and Pittsburgh sleep quality index (PSQI) were applied in adults with and without cardiovascular disease in three Colombian cities, as well as anthropometric measurements and a polysomnogram.

Sense of coherence and dental fear/dental anxiety: A systematic review and meta-analysis.

Aim: The aim of this systematic review and meta-analysis was to evaluate the association between sense of coherence (SOC) and dental fear/dental anxiety.

Methods: Computerized searches were performed in six databases. Gray literature and manual searches were also conducted.

Sleep disturbances, academic performance, depressive symptoms and substance use among medical students in Bogota, Colombia.

Objective: Poor sleep patterns are common in undergraduates and may turn them prone to mood disorders, substance abuse and impaired academic performance. The aim of this study was to assess sleep disturbances among medical students, and whether associations with academic performance, depressive symptoms or substance use were present.

Methods: Cross-sectional study in which 544 medical students of the Pontificia Universidad Javeriana in Bogota, Colombia were included.

Association between obstructive sleep apnea and comorbidities with periodontal disease in adults.

Background: Several studies have reported an association between periodontal disease and obstructive sleep apnea (OSA). However, heterogeneity of results suggests that there is insufficient evidence to support this association.

Aims: The objective of this study was to identify the association between periodontal disease and OSA in adults with different comorbidities.

Sleep characteristics in an adult with sleep complaints in three cities at different altitudes.

Sleep studies conducted at an altitude that is different from the home altitude can yield misleading results regarding the severity of obstructive sleep apnea (OSA). The objective of the present study was to determine the sleep characteristics of a patient undergoing polysomnography (PSG) in three Colombian cities at different altitudes (Bogotá, at 2,640 m above sea level [ASL]; Bucaramanga, at 959 m ASL; and Santa Marta, at 15 m ASL). The patient was an obese man with diabetes and suspected OSA.

The associations between sleep disorders and anthropometric measures in adults from three Colombian cities at different altitudes.

Background: Sleep disorders are common but underdiagnosed conditions, which are associated with obesity. In Colombia, the distribution of sleep disorders remains unclear. We aimed to describe the distribution of sleep disorders, according to demographic, geographic and anthropometric characteristics, in adult Colombian populations.

[Tuberculin skin test conversion and association with occupation and demographic characteristics in workers at San Ignacio University Hospital].

Objectives To establish the prevalence of positivity and conversion rate of the tuberculin skin test in workers of our hospital, and to describe the related demographic and occupational characteristics. Materials and Methods An observational, descriptive study was conducted in a cohort of hospital workers who underwent the tuberculin skin test. The positivity of the test was defined as a result of greater than or equal to 10 mm, and conversion was defined as an increase of 6 or 10 mm with respect to the initial test.

[Pain prevalence in patients with and without OSAHS subjected to a polysomnogram: A cross-sectional study].

Background And Objectives: Sleep disturbances apparently have a negative effect on pain or the appearance of pain itself. This suggests the need to determine whether there could be a relationship between obstructive sleep apnea-hypopnea syndrome (OSAHS) and this phenomenon. The objective of this study was to determine the pain prevalence in a population who underwent polysomnography.
