Defining polypharmacy in the elderly: A systematic review protocol
Introduction: Ageing-along with its associated physiological and pathological changes-places individuals at a higher risk of multimorbidity and treatment-related complications. Today, polypharmacy, a common and important problem related to drug use, occurs subsequent to this multimorbidity in the elderly in all populations. In recent decades, several scientific investigations have studied polypharmacy and its correlates, using different approaches and definitions, and their results have been inconclusive. Differences in definitions and approaches in these studies form a barrier against reaching a conclusion regarding the risk factors and consequences of polypharmacy. It is therefore imperative to establish an appropriate definition of polypharmacy. Methods and analysis: A systematic review will be conducted using PubMed, Scopus, Web of Science, EMBASE, PsycINFO and AgeLine bibliographic databases, as well as the grey literature on polypharmacy in older adults to answer these two questions: What definitions in the literature are being used for polypharmacy in older people?, and Which definitions are more comprehensive and applicable? 2 independent reviewers will conduct the primary screening of the articles and data extraction, and eligible sources will be selected after discussing nonconformities. All extracted data from selected articles will be categorised based on the type of study participants, study design and setting, the methodological quality of primary studies and any other potential source of heterogeneity, and results will be summarised in a table, which will contain the levels of evidence and methodological quality of the included studies. The most comprehensive definition of polypharmacy will be selected from the final list of definitions through an international expert webinar. Ethics and Dissemination: This research is exempt from ethics approval because the work is carried out on published documents. We will disseminate this protocol in a related peer-reviewed journal
Investigating the role of temperature on thermal stress and fracture propagation in geothermal systems
Available geothermal energy extractable by conventional techniques is in dry and comparatively impermeable
rocks. Enhanced Geothermal System (EGS) technologies enhance geothermal resources in the hot dry rock (HDR) through fracture
operations, usually through hydro-shearing. Large scale deployment of geothermal power production requires the demonstration of
successful EGS projects extracting heat from reservoirs constituting a variety of geological conditions. In this part, numerical
models are very important to show how geothermal power plant operations can be less risky and safer. Owing the fact that, some
major challenges in these operations are interaction between shear and tensile fractures with natural faults. These interactions can
be seen in two different cases, either these faults are badly oriented or these faults are fill in pore fluids or gases which are mainly
high pressure. Fluids and gases are important on account for because of the fact that these pore fluids can over whelmed the
injection pressure and cause well blow out. Furthermore, to prevent these operational hazards, we use field data and analysis in
combination with experimental tests and numerical/analytical models with finite element method software such as COMSOL
Multiphysics. Further work will be required for improving enhanced geothermal production by optimizing hydro-shearing
practices
General Aviation Weather Encounter Case Studies
This study presents a compilation of 24 cases involving general aviation (GA) pilots’ weather encounters over the continental U.S. The project team interviewed pilots who had experienced a weather encounter, and we examined their backgrounds, flight experience, and weather encounter details. Results from meteorological data analysis for each weather encounter were consistent with findings of larger GA weather accident studies in terms of the types of hazards encountered and flight phase during which the encounters occurred. Investigation of pilot weather products and the sources from which they were obtained revealed a lack of uniformity of pre-flight data sources and underutilization of available en route flight information services. The team used these results to develop a set of pilot weather education and training recommendations intended to reduce the number and severity of weather encounters
Aging Puerto Ricans’ Experiences of Depression Treatment: A New Ethnographic Exploration
PurposeTo examine aging Puerto Ricans’ experiences with and perceptions of depression treatment.Methodology/approachIn-depth analysis of eight exemplary cases from ethnographic interviews with a subsample of 16 aging Puerto Ricans in the Boston area who are part of the Boston Puerto Rican Health Study.FindingsThe results show that respondents were resistant to accepting pharmacological treatment for their depression, and they often characterized antidepressants as “dope.” Moreover, they claimed that in addition to their health problems, social stressors such as financial strain, lack of jobs, housing problems, and social isolation are triggering or contributing to their depression. Because of this, they express reluctance in accepting clinical treatment only, and suggest that broader social issues and other health needs ought to be addressed as part of an effective treatment. For many, pharmacological treatment is acceptable only in the more severe forms of depression.Research limitations/implicationsThese results have important implications for improving the quality of depression treatment and reducing health disparities for mainland Puerto Ricans.Originality/value of chapterEven though recent studies continue to show a high frequency of depression among Puerto Ricans, issues of treatment quality are still understudied and ethnographic accounts are especially lacking. Our study offers an exploratory investigation of this unresolved research issue
Integrating a suicide prevention program into the primary health care network: A field trial study in Iran
Objective. To describe and evaluate the feasibility of integrating a suicide prevention program with Primary Health Care services and evaluate if such system can improve screening and identification of depressive disorder, reduce number of suicide attempters, and lower rate of suicide completion. Methodology. This was a quasi-experimental trial in which one community was exposed to the intervention versus the control community with no such exposure. The study sites were two counties in Western Iran. The intervention protocol called for primary care and suicide prevention collaboration at different levels of care. The outcome variables were the number of suicides committed, the number of documented suicide attempts, and the number of identified depressed cases. Results. We identified a higher prevalence of depressive disorders in the intervention site versus the control site (� 2 = 14.8, P < 0.001). We also found a reduction in the rate of suicide completion in the intervention region compared to the control, but a higher prevalence of suicide attempts in both the intervention and the control sites. Conclusion. Integrating a suicide prevention program with the Primary Health Care network enhanced depression and suicide surveillance capacity and subsequently reduced the number of suicides, especially in rural areas. © 2015 Seyed Kazem Malakouti et al
Neural network based simulation of sea-state sequences
The present PhD study, in its first part, uses artificial neural networks (ANNs), an optimization technique called simulated annealing, and statistics to simulate the significant wave height (Hs) and mean zero-up-crossing period ( ) of 3-hourly sea-states of a location in the North East Pacific using a proposed distribution called hepta-parameter spline distribution for the conditional distribution of Hs or given some inputs. Two different seven- network sets of ANNs for the simulation and prediction of Hs and were trained using 20-year observed Hs’s and ’s. The preceding Hs’s and ’s were the most important inputs given to the networks, but the starting day of the simulated period was also necessary. However, the code replaced the day with the corresponding time and the season. The networks were trained by a simulated annealing algorithm and the outputs of the two sets of networks were used for calculating the parameters of the probability density function (pdf) of the proposed hepta-parameter distribution. After the calculation of the seven parameters of the pdf from the network outputs, the Hs and of the future sea-state is predicted by generating random numbers from the corresponding pdf. In another part of the thesis, vertical piles have been studied with the goal of identifying the range of sea-states suitable for the safe pile driving operation. Pile configuration including the non-linear foundation and the gap between the pile and the pile sleeve shims were modeled using the finite elements analysis facilities within ABAQUS. Dynamic analyses of the system for a sea-state characterized by Hs and and modeled as a combination of several wave components were performed. A table of safe and unsafe sea-states was generated by repeating the analysis for various sea-states. If the prediction for a particular sea-state is repeated N times of which n times prove to be safe, then it could be said that the predicted sea-state is safe with the probability of 100(n/N)%. The last part of the thesis deals with the Hs return values. The return value is a widely used measure of wave extremes having an important role in determining the design wave used in the design of maritime structures. In this part, Hs return value was calculated demonstrating another application of the above simulation of future 3-hourly Hs’s. The maxima method for calculating return values was applied in such a way that avoids the conventional need for unrealistic assumptions. The significant wave height return value has also been calculated using the convolution concept from a model presented by Anderson et al. (2001).EThOS - Electronic Theses Online ServiceGBUnited Kingdo
Scattering Theory for Jacobi Operators with Steplike Quasi-Periodic Background
We develop direct and inverse scattering theory for Jacobi operators with
steplike quasi-periodic finite-gap background in the same isospectral class. We
derive the corresponding Gel'fand-Levitan-Marchenko equation and find minimal
scattering data which determine the perturbed operator uniquely. In addition,
we show how the transmission coefficients can be reconstructed from the
eigenvalues and one of the reflection coefficients.Comment: 14 page
Experiences of stigma in healthcare settings among adults living with HIV in the Islamic Republic of Iran
<p>Abstract</p> <p>Background</p> <p>People living with HIV (PLHIV) sometimes experience discrimination. There is little understanding of the causes, forms and consequences of this stigma in Islamic countries. This qualitative study explored perceptions and experiences of PLHIV regarding both the quality of healthcare and the attitudes and behaviours of their healthcare providers in the Islamic Republic of Iran.</p> <p>Methods</p> <p>In-depth, semi-structured interviews were held with a purposively selected group of 69 PLHIV recruited from two HIV care clinics in Tehran. Data were analyzed using the content analysis approach.</p> <p>Results and discussion</p> <p>Nearly all participants reported experiencing stigma and discrimination by their healthcare providers in a variety of contexts. Participants perceived that their healthcare providers' fear of being infected with HIV, coupled with religious and negative value-based assumptions about PLHIV, led to high levels of stigma. Participants mentioned at least four major forms of stigma: (1) refusal of care; (2) sub-optimal care; (3) excessive precautions and physical distancing; and (4) humiliation and blaming. The participants' healthcare-seeking behavioural reactions to perceived stigma and discrimination included avoiding or delaying seeking care, not disclosing HIV status when seeking healthcare, and using spiritual healing. In addition, emotional responses to perceived acts of stigma included feeling undeserving of care, diminished motivation to stay healthy, feeling angry and vengeful, and experiencing emotional stress.</p> <p>Conclusions</p> <p>While previous studies demonstrate that most Iranian healthcare providers report fairly positive attitudes towards PLHIV, our participants' experiences tell a different story. Therefore, it is imperative to engage both healthcare providers and PLHIV in designing interventions targeting stigma in healthcare settings. Additionally, specialized training programmes in universal precautions for health providers will lead to stigma reduction. National policies to strengthen medical training and to provide funding for stigma-reduction programming are strongly recommended. Investigating Islamic literature and instruction, as well as requesting official public statements from religious leaders regarding stigma and discrimination in healthcare settings, should be used in educational intervention programmes targeting healthcare providers. Finally, further studies are needed to investigate the role of the physician and religion in the local context.</p
Psychometric properties of the 12-item WHODAS applied through phone survey: an experience in PERSIAN Traffic Cohort
Background Due to limited capability to function in post-injury daily life injury, survivors need to be reliably assessed without need to commute more than necessary. The key action is to determine the level of functioning difficulties. Having the opportunity of conducting a national post-crash traffic safety and health cohort study, we aimed to translate into Persian and assess the psychometric properties of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) through phone surveys six month post injury. Methods First, having World Health Organization permission, we tested the translation validity by forward translation, expert panel evaluation, back-translation, pre-testing and cognitive interviewing, and finalizing the Persian WHODAS. Then, through a psychometric study within a national cohort platform, the validity, reliability and applicability of the 12-item WHODAS was assessed through phone surveys. We included data of 255 road traffic injury patients enrolled from the cohort at six-month follow-up. The psychometric assessment (internal consistency reliability and stability reliability) was conducted on test-retest data of 50 patients with an average 7-day time span. An exploratory factor analysis tested the construct validity using extraction method of principal component factor and oblique rotation on data from 255 patients. Regarding the multiple criteria including an eigenvalue > 0.9, Cattell's scree test, cumulative variance, and the theoretical basis, the minimum number of factors were retained. Data were analyzed using STATA statistical software package. Results The respondents were mostly male (81%), employed (71%), educated (87%), and with a mean age of 37.7(14.9). The Persian version had high internal consistency reliability (Cronbach's alpha = 0.93) and excellent stability reliability (ICC = 0.97, 95% CI: 0.92-0.98). An exploratory factor analysis retained four factors defining 86% of all the variance. Factors of Self-care, Mobility, and Cognition were completely retained. Conclusions The brief Pesrian WHODAS 2.0 was highly reliable and valid to be applied through phone interviews post injury
