: The aim of this study was to examine the relationship between shift-work disorder (SWD) and environmental and somatic factors related to falling asleep among rapidly rotating shift workers in a manufacturing industry. A total of 556 male workers were recruited to complete a self-administered questionnaire regarding age, shift work experience, lifestyle, and family structure; the Epworth sleepiness scale (ESS); the Pittsburgh sleep quality index (PSQI); and the Horne and Ostberg questionnaire, a questionnaire for environmental and somatic factors related to falling asleep. We classified workers according to having SWD or not, and compared workers with SWD with those without this disorder in terms of all items covered in the aforementioned questionnaires. A total of 208 workers (62.8%) working rapidly rotating shifts were diagnosed with SWD. The ESS and PSQI scores and scores for environmental and somatic factors were significantly higher in workers with SWD than in those without this disorder. The ESS scores and scores for environmental and somatic factors were also associated with SWD in the logistic regression analyses. We suggest that susceptibility to SWD in the manufacturing industry may be associated with environmental and somatic factors related to falling asleep.

“…The sleepiness of shift workers and day workers at work was measured using the Japanese version of the Epworth Sleepiness Scale (ESS) [14], which consists of eight items rated on a scale from 0 to 3, yielding total scores between 0 and 24. A score of ≥ 11 may indicate excessive daytime sleepiness.…”

The taste detection system for oral fatty acid may be related to obesity. In addition, sleep is intrinsically and closely related to food intake and metabolism. However, the association of gustatory salivation with body mass index (BMI), daytime sleepiness, or sleep habits is largely unknown. Therefore, we evaluated the relationship between gustatory salivation and BMI, Epworth sleepiness scale (ESS, a daytime sleepiness scale) or sleep habits among 26 healthy young individuals (20 males and 6 females; mean age: 26.0 ± 4.3 years). We also measured the saliva flow rate (SFR) that was induced by gum-chewing or each of three prototypical tastants (acetic acid, sucrose, and NaCl). Further, the SFR was induced by fatty acid, provided as oleic acid (OA) homogenized in non-fat milk. All participants showed normal rates of salivation during resting and gum-chewing states. The increase in the SFR induced by OA, but not by each of the three tastants, was associated with BMI. Moreover, both daytime sleepiness level and frequency of snoring were associated with the increase in the SFR induced by NaCl. These results suggest that BMI is associated with salivation induced by oral fatty acid exposure. Additionally, the regulatory mechanism for the NaClinduced salivation reflex may have a relationship with impairments of the respiratory control system that are related to snoring during sleep and lead to daytime sleepiness because of insufficient sleep. Thus, measurement of gustatory salivation might contribute to the evaluation and prevention of obesity and sleeprelated breathing disorders.

“…The clinical severities of iRLS patients were assessed with the IRLSS Group rating scale for RLS symptoms, the Japanese version of the ESS (Epworth Sleepiness Scale) (Takegami et al, 2009) for daytime sleepiness, and the Pittsburgh Sleep Quality Index (PSQI) (Doi et al, 2000) for subjective sleep quality. In the current study, the IRLSS scores varied from 9 to 36, indicating that RLS symptoms ranged from mild to severe.…”

Although D2/3 agonists have been used as a first-line medication for idiopathic restless legs syndrome (iRLS), findings on D2/3 receptors have been inconsistent. Here, we aimed to clarify the contribution of D2/3 receptor function to the clinical symptoms of iRLS by comparing the binding potential (BP ND ) of [ 11 C]raclopride with clinical improvements after D2/3 stimulation by pramipexole. Eight drug-naïve, iRLS patients and eight age-matched healthy subjects were scanned with positron emission tomography (PET). After PET scans, all patients received pramipexole (0.125 mg) orally for 2 weeks. Patients were evaluated every day with several standardized clinical tests. The BP ND values were compared using regions of interest and voxel-based methods. Results showed that the mean magnitude of [ 11 C]raclopride BP ND in the mesolimbic dopamine region (nucleus accumbens (NA) and caudate) was significantly lower in the iRLS group. No significant differences between groups were observed in the putamen. The NA [ 11 C]raclopride BP ND levels correlated negatively with clinical severity scores and positively with the degree of posttreatment improvement in iRLS. The present results suggest that alterations in mesolimbic D2/3 receptor function reflect the pathophysiology of iRLS, and the baseline availability of D2/3 receptors may predict the clinical outcome after D2/3 agonist treatment.
