“…Both of these scales assess the momentary/acute level of alertness-sleepiness, whereas the ESS enables the measurement of an individual's global level of sleepiness, measuring a more "trait"-like aspect of sleepiness. The latter is the sleepiness scale most used in research and clinical settings, however, its measurement properties need more high methodological quality studies (Kendzerska, Smith, Brignardello-Petersen, Leung, & Tomlinson, 2014). The SSS is based on seven statements, describing a mixture of sleep propensity, energy/fatigue and cognitive performance (Shen, Barbera, & Shapiro, 2006).…”

DSPS-4: a Brief Measure of Perceived Daytime Sleepiness

2017

Sleepiness is a key issue in sleep medicine but its definition remains ambiguous and difficult to address. Some studies have reported that sleepiness should be conceptualized as a multidimensional construct. One of these dimensions is sleepiness propensity accurately assessed by the Epworth Sleepiness Scale. However, in the literature, data on other important sleepiness dimensions, such as sleepiness perception, are lacking. In an attempt to fulfil the literature gaps, this study aims at presenting data regarding the development of a brief self-report instrument to assess daytime sleepiness perception, the Daytime Sleepiness Perception Scale (DSPS-4). A sample of 692 undergraduate Medicine students was initially enrolled. The sample was randomly split in order to perform independent exploratory (EFA) and confirmatory factor analyses (CFA). A one-factor solution was examined. The DSPS-4 showed good indicators of reliability and validity. The CFA confirmed the one-factor structure of the DSPS-4. The unidimensional structure of the scale was invariant for both sexes. Results highlight the usefulness of DSPS-4 to measure and assess sleepiness perception at daytime. The short length of this scale enables its incorporation in routine assessment protocols for example regarding insomnia complaints.However, more studies are now required to check its suitability for other samples, specifically well-defined clinical groups.

Daytime sleepiness in patients with type 2 Diabetes Mellitus – a prospective cohort study

et al. 2016

Introduction: Daytime sleepiness is an independent factor for increased health care utilization and all cause mortality. Diabetic patients are more likely to be sleepy during the daytime than non-diabetics. Objectives:To examine factors influencing the evolution of daytime sleepiness in patients with type 2 diabetes (T2D) in a two-year followup study.Methods: Patients (N=145) aged from 40 to 60 of both genders were consecutively recruited and evaluated for comorbidity severity (Charlson Comorbidity Index), depressive symptoms (Beck Depression Inventory, BDI II), sleep quality (Pittsburgh Sleep Quality Index) and physical activity levels (International Physical Activity Questionnaire, IPAQ). Daytime sleepiness was assessed by the Epworth Sleepiness Scale (ESS).Results: Excessive daytime sleepiness (ESS>10) was found in 51 (35.2%) patients. At baseline, men had more excessive daytime sleepiness; however, women evolved with more sleepiness after two years. Levels of physical activity were independently associated with excessive daytime sleepiness: patients with a sedentary lifestyle developed worse levels of daytime sleepiness after two years. Active lifestyle was more beneficial for reducing daytime sleepiness in women. In this study, among all patients, levels of physical activity (IPAQ) improved after two years. Conclusion:Excessive daytime sleepiness affects approximately 1/3 of T2D patients and women evolve with more sleepiness. Better levels of physical activity are independently associated with less daytime sleepiness. Implementing physical exercise possibly break a chain involving sleep-wake alterations and comorbidites in T2D. Gender differences show that these effects are more important for women. IntroductionDaytime sleepiness is a major public health issue and is an independent factor for increased health care utilization and all cause mortality [1][2][3] . Previous studies suggest that diabetic patients are more likely to be sleepy during the daytime than non-diabetics [4][5][6] Patients with type 2 diabetes (T2D) commonly present with sleep abnormalities e.g. restless legs syndrome [7], obstructive sleep apnea [8], circadian alterations [9] and nervous system abnormalities [10,11]. Given these evidences, daytime sleepiness in diabetic patients are probably of multifactorial origin.Obesity and obstructive sleep apnea (OSA) cooccur frequently with T2D [12,13]. Furthermore, short sleep duration increases the risk for the development of obesity [14] and is associated with increased incidence of T2D [15]. Importantly, poor sleep quality affects more than half of patients with T2D and relates to depressive symptoms [16]. Arterial hypertension, cerebrovascular events, anxiety, depression, cognitive alterations and dementia are other comorbidities frequent in T2D that potentially influence daytime sleepiness [4,[17][18][19]. All this evidence demonstrate that these comorbid conditions are multilaterally related.In T2D, sedentary life contributes to worse anthropometric measures, worse quality of lif...

Objective: To describe the orthodontic treatment of a nongrowing 30-year-old woman with asymmetric severe skeletal Class II malocclusions (asymmetric Angle Class II), large overjet (16 mm), large overbite (8 mm), two congenitally missing mandibular incisors (presenting a deciduous anterior tooth), and signs and symptoms of temporomandibular joint disorder (TMD). Materials and Methods: We used novel improved super-elastic Ni-Ti alloy wires (ISWs) combined with Ni-Ti alloy coil springs, power hooks, and a zygomatic implant as reinforced anchorage to provide a constant and continuous mild force to the dentition. Results: We successfully distalized maxillary molars, premolars, and retracted anterior teeth and corrected the asymmetric Angle Class II molar relationship using this system of zygomatic anchorage in conjunction with ISWs, Ni-Ti alloy open-coil springs, and crimpable power hook. The maxillary molars were distalized, and postero-occlusal relationships were improved to achieve Class I canine and molar relationships on both sides. Intrusion of the upper molars made the mandibular plane close. Ideal overbite and overjet relationships were established. Facial esthetics were improved with decreased upper and lower lip protrusion, and no symptoms of TMD were observed after treatment. Conclusion: The orthodontic treatment described here is a promising anchorage technique alternative to traditional techniques to improve severe skeletal Class II with TMD.
