BACKGROUND Parkinson's disease (PD) is a neurodegenerative disorder with fluctuating symptoms. To aid the development of a system to evaluate people with PD (PwP) at home (SENSE-PARK system) there was a need to define parameters and tools to be applied in the assessment of 6 domains: gait, bradykinesia/hypokinesia, tremor, sleep, balance and cognition. OBJECTIVE To identify relevant parameter...

We investigate properties and examples of iterated planar piecewise parabolic (PWP) maps, including those induced by two-torus parabolic maps and their inverses. PWP maps are areapreserving maps that have constant linearizations but only one eigenvector with eigenvalue one. We obtain necessary and sufficient conditions for a two-torus parabolic map to be invertible. For noninvertible PWP maps, ...

Some distributed applications function well only when guarantees are made on the maximum latency which the applications’ packets will experience. Common packet-switched networks, such as the current public Internet, do not provide straightforward mechanisms for deriving such guarantees. Two approaches to the problem of bounding packet-switched network latency are presented: PWP-Sporadic, and PW...

The quality of life (QoL) of informal caregivers can be adversely affected by a number of factors. This issue, however, has not been well explored for carers of people with Parkinson's (PwP), with research largely restricted to the assessment of caregiver burden and caregiver strain. This study aims to determine the main influences on carer QoL in this population and consider results in the con...

BACKGROUND Differentiation of pulmonary arterial hypertension (PAH) and pulmonary venous hypertension (PVH) often requires right heart catheterization (RHC). We sought to determine whether a combination of clinical and echocardiographic variables could predict the pulmonary diastolic to wedge (PAd-PWP) gradient and thus differentiate patients with PAH and PVH. METHODS We prospectively enrolle...

People with Parkinson’s disease (PwP) have been suggested to be more vulnerable negative psychological and psycho-social effects of the COVID-19 pandemic. Our aim was assess potential impact pandemic in PwP. A Danish/Swedish cohort 67 PwP analysed. Health-related quality life (HRQL), depression, anxiety, apathy, sleep motor symptom-scores were included analysis. Additionally, Danish participant...

INTRODUCTION Parkinson's disease (PD) incidence and prevalence, particularly in Western countries, is greater in rural areas. Despite several epidemiological studies on PD in Australia, there are few publications addressing specific issues facing people with Parkinson's disease (PWP) in regional, rural and remote areas. This study looked at the dynamics of healthcare delivery to PWP and their c...

Most existing elasticity estimates for the pulp and paper industry are based on aggregate products (e.g., total paper, paperboard, or paper except newsprint). Using United States data, we present and evaluate econometric output supply models for four relatively disaggregated paper products: newsprint paper (NP), printing/writing paper (PWP), tissue paper (TP), and packaging paper (PP). Sample p...

BACKGROUND We implemented a hospital-based prevention with positives (PwP) intervention among people living with HIV (PLHIV) that included HIV transmission risk screening, short HIV prevention messages, family planning, HIV disclosure counseling, and partner HIV testing at five hospitals in Thailand. We assessed changes in sexual risk behaviors among PLHIV who received the PwP services at the h...

This paper presents a computer-vision based marker-free method for gait-impairment detection in Patients with Parkinson's disease (PWP). The system is based upon the idea that a normal human body attains equilibrium during the gait by aligning the body posture with Axis-of-Gravity (AOG) using feet as the base of support. In contrast, PWP appear to be falling forward as they are less-able to ali...
