Parkinson disease is a progressive degenerative disease causing motor and non-motor symptoms. Sleep disturbance is a common non-motor symptom and significantly affect the day to day activities of patients and their quality of life. Though common, sleep disturbance is an under diagnosed feature of Parkinson disease (PD). Night-time sleep disturbances have been reported in as many as 60 to 98% of...

Poor sleep is an increasing problem in modern society, but most previous studies on the association between sleep and mortality rates have addressed only duration, not quality, of sleep. The authors prospectively examined the effects of sleep disturbances on mortality rates and on important risk factors for mortality, such as body mass index, hypertension, and diabetes. A total of 16,989 partic...

This paper presents an oscillometric blood pressure (BP) measurement approach based on the active control schemes of cuff pressure. Compared with conventional electronic BP instruments, the novelty of the proposed BP measurement approach is to utilize a variable volume chamber which actively and stably alters the cuff pressure during inflating or deflating cycles. The variable volume chamber is...

Human management activities have altered the frequency and intensity of ecosystem disturbance often with enormous impacts on landscape structure and composition. One additional and under-appreciated way in which humans have altered disturbance regimes is through the introduction of invasive non-native species, themselves capable of modifying existing disturbance regimes or introducing entirely ...

In the last week of November 2012, we announced that a strong electrotelluric disturbance, which we judged to be a Seismic Electric Signal (SES) activity, was recorded at station Assiros located in Northern Greece. This disturbance was actually followed by an Mw5.8 earthquake on 8 January 2013 in North-Eastern Aegean Sea. Here we show that, by analyzing this SES activity and employing the natur...

877 Race/Ethnicity and Sleep Disturbances in US Adults—Chen et al. INTRODUCTION The prevalence of sleep disordered breathing (SDB), short sleep duration, and insomnia has increased substantially over the past two decades.1,2 Epidemiologic studies have linked sleep disturbances to adverse health outcomes including obesity,3 hypertension,3 cardiovascular disease (CVD),3,4 premature mortality,5,6 ...

The main purpose of the present research was to explore gender-related associations between sleep disturbance and perfectionism dimensions in a large sample of undergraduate students. Perfectionism dimensions have been assessed using the Portuguese version of the Multidimensional Perfectionism Scale (Hewitt and Flett, 1991 , J Pers Soc Psychol 60:456; Soares et al., 2003 , Rev Port Psicossom 5:...

Sleep disturbances are common among alcohol-dependent individuals and can increase risk of relapse. The current study compares subjective and objective measures of sleep quality and duration and describes the prevalence of baseline sleep disturbances in an inpatient population of alcoholics undergoing their first week of detoxification. At baseline, the PSQI revealed that 79% of participants we...

Sleep disturbances are routinely encountered in Alzheimer's disease (AD) and affect about 25-40% of patients in the mild-to-moderate stages of the disease. In many, sleep pathology may represent a symptom of the underlying neurodegeneration. However, a history of sleep disruption occurring years prior to onset of cognitive symptoms could represent a potential risk factor for AD. The aim of the ...
