Barriers and facilitators to an outreach rehabilitation program delivered in nursing homes after hip fracture surgical repair  [PDF]
Donna M. Wilson, Sandra L. Robertson, C. Allyson Jones, D. W. C. Johnston, Lauren A. Beaupre
Advances in Aging Research (AAR) , 2013, DOI: 10.4236/aar.2013.21006

Objective: To identify and understand facilitators and barriers to implementing an Outreach rehabilitation program designed to improve post-operative recovery following hip fracture in long-term care residents. Residents of nursing home facilities are at considerable risk of hip fracture and minimal recovery following a hip fracture. Methods: Data were gathered over June-August, 2012 through semi-structured interviews or focus groups. Fifteen persons (n = 15) who were members of the Outreach rehabilitation team (n = 8) or relevant nursing home staff (n = 7) were interviewed. Data analysis was guided by principles of grounded theory method. Findings: Three major themes that contributed to or hindered the Outreach rehabilitation program emerged, namely, 1) the division, the separate operation and delivery of rehabilitation services; 2) building bridges, or negotiating ways to communicate and work together, and 3) strength in the structure, the acceptance of the program and the perceived benefits of the program. One main challenge to program implementation con- cerned coordinating additional rehabilitation with the rehabilitation provided within the nursing homes. Facility staff was largely unaware of the program and were unprepared to work with Outreach team members. As the program progressed, the facility staff and Outreach team were able to collaborate to overcome resident health issues impeding recovery such as cognitive impairment, language barriers and post-surgical pain control needs. Facilitators included the consistency of Outreach team members and accessible facility staff, which contributed to effective communication and trust between the Outreach team and facility staff. Facilitators also included support for the program by the Outreach team and facility staff, as well

Physical activity in persons with Parkinson disease: A feasibility study  [PDF]
C. Allyson Jones, Marguerite Wieler, Jennifer Carvajal, Logan Lawrence, Robert Haennel
Health (Health) , 2012, DOI: 10.4236/health.2012.431173
Abstract: Background: Physical activity for persons with Parkinson Disease (PD) is recommended yet little is known about the physical activity levels in this patient population. The primary aim was to assess the feasibility of using a direct measurement and self-report measure of physical activity in patients with PD. Methods: Physical activity was recorded in 11 out-patients with mild to moderate PD. An accelerometer based sensor system (SenseWear Pro Armband?) which was worn continuously over 2 days was used to measure physical activity. Minute by minute energy expenditure and steps per day were recorded. Self-report physical activity was measured using the Short QUestionnaire to ASsess Health-enhancing physical activity (SQUASH) which assessed average weekly activity. Results: Using the accelerometer based sensor system, 83% of the day was spent in sedentary activity with the majority active time spent at a light intensity (2.7 [SD 2.0] hrs/day). Self-reported mean number of hours for activities greater than 2.0 METs was 3.4 (SD 1.5) hrs/day. Although the overall time spent in activity did not differ between the accelerometer and SQUASH, partici- pants reported a higher proportion of activities at the moderate and vigorous intensities than the accelerometer recorded. Conclusions: Measurement of physical activity is a challenge in persons with PD given the disease-related symptoms. We found that, by all accounts, a self-report measure of physical activity should be complemented with a direct measure of physical activity.
Mobility of Vulnerable Elders (MOVE): study protocol to evaluate the implementation and outcomes of a mobility intervention in long-term care facilities
Susan E Slaughter, Carole A Estabrooks, C Allyson Jones, Adrian S Wagg
BMC Geriatrics , 2011, DOI: 10.1186/1471-2318-11-84
Abstract: This longitudinal, quasi-experimental study is designed to demonstrate the effect of the sit-to-stand activity carried out by residents in the context of daily care with health care aides. In three intervention facilities health care aides will prompt residents to repeat the sit-to-stand action on two separate occasions during each day and each evening shift as part of daily care routines. In three control facilities residents will receive usual care. Intervention and control facilities are matched on the ownership model (public, private for-profit, voluntary not-for-profit) and facility size. The dose of the mobility intervention is assessed through the use of daily documentation flowsheets in the health record. Resident outcome measures include: 1) the 30-second sit-to-stand test; 2) the Functional Independence Measure; 3) the Health Utilities Index Mark 2 and 3; and, 4) the Quality of Life - Alzheimer's Disease.There are several compelling reasons for this study: the widespread prevalence of limited mobility in this population; the rapid decline in mobility after admission to a long-term care facility; the importance of mobility to quality of life; the increased time (and therefore cost) required to care for residents with limited mobility; and, the increased risk of injury for health workers caring for residents who are unable to stand. The importance of these issues is magnified when considering the increasing number of people living in long-term care facilities and an aging population.This clinical trial is registered with ClinicalTrials.gov (trial registration number: NCT01474616).Immobility is a major factor contributing to a reduced quality of life and preventable adverse events among older adults living in residential long-term care (LTC). Of the more than 150,000 older Canadians living in LTC facilities [1] almost 90% have some type of reduced mobility, [2] with approximately 40% of LTC residents with dementia losing their ability to walk annually [3,4].
The burden of multiple sclerosis: A community health survey

Health and Quality of Life Outcomes , 2008, DOI: 10.1186/1477-7525-6-1
Abstract: A representative sample of adults (18 years or older) from the cross sectional population health survey, CCHS 1.1, was examined to compare scores on the Health Utilities Index Mark 3 (HUI3), a generic preference-based HRQL measure, of respondents with (n = 302) and without (n = 109,741) MS. Selected sociodemographic covariates were adjusted for in ANCOVA models. Normalized sampling weights and bootstrap variance estimates were used in the analysis.The mean difference in overall HUI3 scores between respondents with and without MS was 0.25 (95% CI: 0.20, 0.31); eight times greater than the clinically important difference. The largest differences in scores were seen with the ambulation (0.26; 95% CI: 0.20, 0.32) and pain attributes (0.14; 95% CI: 0.09, 0.19). Clinically important differences with dexterity and cognition were also observed.While the proportion of the Canadian population with MS is relatively small in comparison to other diseases, the magnitude of the burden is severe relative to the general population.The diverse symptoms associated with multiple sclerosis (MS) adversely impact health-related quality of life (HRQL) which, in turn, is manifested in extensive physical, psychosocial and economic burden [1-3]. Although the assessment of HRQL in MS is well recognized as an important clinical assessment tool [4], burden of morbidity of persons with MS in comparison with the general population is largely unknown.The Expanded Disability Status Scale (EDSS) is the primary disease specific health measure for MS [5], but it is heavily weighted toward ambulation and is unable to provide a broader comparison of HRQL attributes among different conditions and the general population. The use of a generic health measure to complement the disease specific health measure is typically advocated for the appraisal of the overall impact of MS.The evaluation of HRQL of persons with MS has been primarily in clinical or patient study groups. Relying solely on these cohorts limit
Influences on the study of Vulvar Anatomy and Disease  [PDF]

Open Journal of Obstetrics and Gynecology (OJOG) , 2012, DOI: 10.4236/ojog.2012.23045
Abstract: The study of Gynaecology over the years has been influenced by the culture and social attitudes of society to the body as a whole and to the genital organs in particular. Variations in these attitudes between different cultures and at different times have influenced the subsequent rate of progress in the study of the vulva and its diseases.
Melanosis of the vulva: A long-term follow-up from Brisbane, Australia  [PDF]

Open Journal of Obstetrics and Gynecology (OJOG) , 2012, DOI: 10.4236/ojog.2012.23051
Abstract: Object: To determine if vulvar melanosis progressed to melanoma over a period of 20 years or more. Methods: In 2010 the hospital records from the Royal Brisbane Hospital Vulvar Clinic between 1976 and 1988 were reviewed and cross checked with the state wide Queensland Centre for Gynaecological Cancer (QCGC) data base to determine if any patient had been lost to follow up and subsequently developed a vulvar melanoma. Data collected were stored and analysed using the computer software Statistical Package for the Social Sciences (SPSS) 11.0. Results: None of the 12 patients developed vulval melanoma in the years up to 2010. Conclusion: In this small group, followed for more than 20 years, melanosis was not a precursor of melanoma. One patient, who attended the Vulvar Clinic but was not included in this melanosis study, was found to have co-existing melanosis well away from her melanoma in situ and malignant melanoma at presentation. It was not possible to determine if these findings represented a progression of the benign to malignant. Biopsy of abnormal hyper pigmented vulvar skin is recommended. Current knowledge suggests that vulvar melanosis is a benign condition but to be on the safe side follow up of all hyper pigmented vulval lesions to detect early malignant change is recommended.
A review of conditions altering the permanent appearance of the vulva  [PDF]
Ian S. C. Jones
Open Journal of Obstetrics and Gynecology (OJOG) , 2012, DOI: 10.4236/ojog.2012.24078
Abstract: This article is aimed at providing information on variations in the clinical appearance of the vulva. The appearance of the vulva can be altered by reversible or permanent conditions both of which may result in minor or major changes. Reversible conditions include those associated with infections or acute trauma which results in distortion of the vulva. Some permanent changes are caused by life threatening conditions which are present at birth whereas others develop more slowly or as the result of a deliberate act either traditional female surgery or surgery performed by a registered medical practitioner. To the inexperienced practitioner changes from the normal vulvar appearance can be confusing. The aim of this article is to highlight and categorise changes that can affect the appearance of the vulva. Whatever the presentation the importance of obtaining a detailed history and performing an appropriate, sensitive and thorough examination can not be over emphasised.
Portfolio Size in Stochastic Portfolio Networks Using Digital Portfolio Theory  [PDF]
C. Kenneth Jones
Journal of Mathematical Finance (JMF) , 2013, DOI: 10.4236/jmf.2013.32028

The investment portfolio with stochastic returns can be represented as a maximum flow generalized network with stochastic multipliers. Modern portfolio theory (MPT) [1] provides a myopic short horizon solution to this network by adding a parametric variance constraint to the maximize flow objective function. MPT does not allow the number of securities in solution portfolios to be specified. Integer constraints to control portfolio size in MPT results in a nonlinear mixed integer problem and is not practical for large universes. Digital portfolio theory (DPT) [2] finds a non-myopic long-term solution to the nonparametric variance constrained portfolio network. This paper discusses the long horizon nature of DPT and adds zero-one (0-1) variables to control portfolio size. We find optimal size constrained allocations from a universe of US sector indexes. The feasible size of optimal portfolios depends on risk. Large optimal portfolios are infeasible for low risk investors. High risk investors can increase portfolio size and diversification with little effect on return.

Modern Portfolio Theory, Digital Portfolio Theory and Intertemporal Portfolio Choice  [PDF]
C. Kenneth Jones
American Journal of Industrial and Business Management (AJIBM) , 2017, DOI: 10.4236/ajibm.2017.77059
Abstract: The paper compares three portfolio optimization models. Modern portfolio theory (MPT) is a short-horizon volatility model. The relevant time horizon is the sampling interval. MPT is myopic and implies that investors are not concerned with long-term variance or mean-reversion. Intertemporal portfolio choice is a multiple period model that revises portfolios continuously in response to relevant signals to reduce variance of terminal wealth over the holding period. Digital portfolio theory (DPT) is a non-myopic, discrete time, long-horizon variance model that does not include volatility. DPT controls mean-reversion variances in single period solutions based on holding period and hedging and speculative demand.
Vulvar dystrophies: A long-term Brisbane study of 155 cases  [PDF]
Ian S. C. Jones, Alister Jones
Open Journal of Obstetrics and Gynecology (OJOG) , 2012, DOI: 10.4236/ojog.2012.23042
Abstract: Objective: To review the long-term outcomes for 155 women with a vulvar dystrophy (VD) who attended the Royal Brisbane Hospital Vulvar Clinic between 1976 and 1988. Methods: VD data from Vulvar Diseases Clinic were reviewed and analysed using the computer software Statistical package for the Social Sciences (SPSS) 11.0. Results: Of 155 patients 94 had Lichen Sclerosus (LS), 41 Lichen Simplex Chronicus (LSC) and 20 Mixed Dystrophy (MD). Three patients developed squamous cell carcinomas of the vulva between 10 and 26 years after presentation with a VD. To date only one of these three patients remains alive following treatment. Conclusion: The need for long term follow up is stressed and any of the three types of VD may become malignant. Time from diagnosis to malignant change is not predictive. VD treatments seem to go through phases with the application of potent steroid creams having stood the test of time.
