Sense of coherence, health problems, and presenteeism in Japanese university students.

Aim: Sense of coherence (SOC) is thought to be a major determinant in maintaining health. SOC gained attention recently in the fields of psychiatry after it was reported to be associated with a lowered risk of various health problems. However, the effect of SOC as a buffer against performance impairment caused by health problems is not well known.

Presenteeism in college students: reliability and validity of the Presenteeism Scale for Students.

Objective: Presenteeism is the impaired work performance due to health problems. We aimed to develop a Presenteeism Scale for Students (PSS), and to reveal the existence of presenteeism among students.

Methods: Students (n = 5,701) in 4 national universities in Japan were recruited via the school-based health examination.

Anxiety, neuroticism and oxidative stress: cross-sectional study in non-smoking college students.

Aims: Oxidative stress has gained attention recently in psychiatric medicine and has been reported to be associated with various diseases. However, the psychosocial factors involved in oxidative stress are still not well understood. Thus, the aim of this study was to examine whether anxiety levels and neuroticism were associated with serum oxidative and anti-oxidative status in healthy college students.

Urgency is an independent factor for sleep disturbance in men with obstructive sleep apnea.

Objectives: The relationship between overactive bladder (OAB) symptoms, other than nocturia, and sleep, has not been fully evaluated, although a close relationship between nocturia and sleep disturbance has been reported. In the present study, we evaluated the relationship between OAB symptoms and several polysomnography (PSG) parameters in middle-age men with sleep disturbance, especially to clarify whether urgency as the hallmark symptom of an OAB is independently associated with sleep quality.

Methods: A total of 32 men >40 years of age (mean age 58.

Clinical significance of pulse rate rise during sleep as a screening marker for the assessment of sleep fragmentation in sleep-disordered breathing.

Objective: To assess the clinical utility of the frequencies of transient increases of pulse rate, non-invasively measured with a pulseoximeter, as an indirect indication of the degree of cortical arousal, measured conventionally on an electroencephalogram (EEG), in obstructive sleep apnea-hypopnea syndrome (OSAHS) patients.

Patients And Methods: Thirty-three consecutive patients referred with suspected OSAHS were studied. Polysomnography (PSG) with determination of esophageal pressure (Pes) and pulseoximetry was monitored to identify breathing-related EEG arousal (B-Ar) associated with apnea, hypopnea or respiratory effort and the frequencies of pulse rate increases.
