Patient Portal Implementation and Uptake: Qualitative Comparative Case Study
Authors: Avdagovska Melita , Ballermann Mark , Olson Karin , Graham Timothy , Menon Devidas , Stafinski Tania
Published: June 2020

Background

Giving patients access to their health information is a provincial and national goal, and it is critical to the delivery of patient-centered care. With this shift, patient portals have become more prevalent. In Alberta, the Alberta Health Services piloted a portal (MyChart). There was a need to identify factors that promoted the use of this portal. Furthermore, it was imperative to understand why there was variability in uptake within the various clinics that participated in the pilot.

Objective

This study aims to identify potential factors that could improve the uptake of MyChart from the perspectives of both users and nonusers at pilot sites. We focused on factors that promoted the use of MyChart along with related benefits and barriers to its use, with the intention that this information could be incorporated into the plan for its province-wide implementation.

Methods

A qualitative comparative case study was conducted to determine the feasibility, acceptability, and initial perceptions of users and to identify ways to increase uptake. Semistructured interviews were conducted with 56 participants (27 patients, 21 providers, 4 nonmedical staff, and 4 clinic managers) from 5 clinics. Patients were asked about the impact of MyChart on their health and health care. Providers were asked about the impact on the patient-provider relationship and workflow. Managers were asked about barriers to implementation. The interviews were recorded, transcribed verbatim, and entered into NVivo. A thematic analysis was used to analyze the data.

Results

Results from a comparison of factors related to uptake of MyChart in 5 clinics (2 clinics with high uptake, 1 with moderate uptake, 1 with low uptake, and 1 with no uptake) are reported. Some theoretical constructs in our study, such as intention to use, perceived value, similarity (novelty) of the technology, and patient health needs, were similar to findings published by other research teams. We also identified some new factors associated with uptake, including satisfaction or dissatisfaction with the current status quo, performance expectancy, facilitating conditions, behavioral intentions, and use behavior. All these factors had an impact on the level of uptake in each setting and created different opportunities for end users.

Conclusions

There is limited research on factors that influence the uptake of patient portals. We identified some factors that were consistent with those reported by others but also several new factors that were associated with the update of MyChart, a new patient portal, in the clinics we studied. On the basis of our results, we posit that a shared understanding of the technology among patients, clinicians, and managers, along with dissatisfaction with nonportal-based communications, is foundational and must be addressed for patient portals to support improvements in care.
Use of an Unguided, Web-Based Distress Self-Management Program After Breast Cancer Diagnosis: Sub-Analysis of CaringGuidance Pilot Study
Authors: Lally Robin M , Kupzyk Kevin , Gallo Steve , Berry Donna
Published: June 2020

Background

Unguided, web-based psychoeducational interventions are gaining interest as a way to reach patients while reducing pressure on clinical resources. However, there has been little research on how patients with cancer use these interventions.

Objective

The objective of this analysis was to evaluate how women newly diagnosed with breast cancer used the unguided web-based, psychoeducational distress self-management program CaringGuidance After Breast Cancer Diagnosis while enrolled in a pilot feasibility study.

Methods

Women with stage 0 to II breast cancer diagnosed within the prior three months were recruited from clinics primarily in the Northeastern United States for participation in a 12-week pilot study of CaringGuidance plus usual care versus usual care alone. Usage prompts included sets of emails sent weekly for 12 weeks; standardized congratulatory emails after every two hours of program use, and informative emails for each cognitive-behavioral exercise. Individual user activity on the site was automatically tracked by an analytics system and recorded directly in the CaringGuidance database.

Results

Complete usage data were available for 54 subjects. Ninety-eight percent of the intervention group logged into CaringGuidance independently at least once. Thirty-eight (70%) logged in during all three months, 15 (28%) were intermittent users, and one (2%) was a non-user. Users (n=53) averaged 15.6 (SD 9.85) logins. Mean logins were greatest in month 1 (7.26, SD 4.02) and declined in months 2 (4.32, SD 3.66) and month 3 (4.02, SD 3.82). Eleven (21%) used CaringGuidance with both the frequency and activity level intended at study outset, 9 (17%) exceeded intended frequency and activity (high-high users), and 10 (19%) were below expected usage on both login frequency and activity (low-low users). Low-low users and high-high users differed significantly (P<.001) in the total number of views and unique views of all program components. Change in depressive symptoms and the number of sessions (r=.351) and logins (r=.348) between study months 1 and 2 were significantly correlated (P=.018, .019). Higher baseline distress was associated with more unique views of program resources (r=.281, P=.043). Change in intrusive/avoidant thoughts from baseline to month 3, and the number of users’ unique exercise views were negatively correlated (r=–.319, P=.035) so that more unique exercise views, equated with greater decline in intrusive/avoidant thoughts from baseline to month 3.

Conclusions

These findings favor the hypothesis that the key ingredient is not the amount of program use, but each user’s self-selected activity within the program. More research is needed on the ideal ways to maintain use, and capture and define engagement and enactment of behaviors by people with cancer accessing unguided, self-management web-based programs.
Case-Initiated COVID-19 Contact Tracing Using Anonymous Notifications
Authors: Cheng Weibin , Hao Chun
Published: June 2020

We discuss the concept of a participatory digital contact notification approach to assist tracing of contacts who are exposed to confirmed cases of coronavirus disease (COVID-19); the approach is simple and affordable for countries with limited access to health care resources and advanced technology. The proposed tool serves as a supplemental contract tracing approach to counteract the shortage of health care staff while providing privacy protection for both cases and contacts. This tool can be deployed on the internet or as a plugin for a smartphone app. Confirmed cases with COVID-19 can use this tool to provide contact information (either email addresses or mobile phone numbers) of close contacts. The system will then automatically send a message to the contacts informing them of their contact status, what this status means, the actions that should follow (eg, self-quarantine, respiratory hygiene/cough etiquette), and advice for receiving early care if they develop symptoms. The name of the sender of the notification message by email or mobile phone can be anonymous or not. The message received by the contact contains no disease information but contains a security code for the contact to log on the platform to retrieve the information.
Glottal Replacement in Retrospect
Authors: Titheridge Zoé
Published: June 2020

This research examines the production of glottal replacement i.e., /t/-glottaling in the speech of Edinburgh residents in 1975 and compares its findings to those in the existing literature to provide a better understanding of the variant’s spatial and temporal development in the area. Most of the results concur with those previously described as phonological factors and social class are concluded to be strong predictors of /t/-glottaling. Variation in preferred phonological environments is argued to be an effect of polygenetic roots. Absence of constraining effect for age is interpreted in light of the variant’s history in the region.
Towards a historical anthropology of Upland Laos
Authors: Tappe Oliver
Published: June 2020

When travelling across Houaphan province in upland north-eastern Laos in 2010, I took with me a copy of James Scott’s (2009) Art of Not Being Governed. This thought-provoking book offered fresh perspectives to exploring this ‘Zomian’ landscape and its ethnolinguistically diverse population. Indeed a historical frontier zone of refuge and opportunity, Houaphan’s forested mountains always constituted an escape option for people facing (Siamese, Vietnamese, lowland Lao, or French colonial) imperial interventions (Boutin 1937; Tappe 2015). Even today, the different ethnic groups of Houaphan demonstrate a wide range of flexible livelihoods such as swidden cultivation that carried them through times of crisis and war at the margins of lowland state formations, often seeking creative ways to keep state authorities at bay.

La imagen corporativa es un componente fundamental en la proyección de las organizaciones hacia sus distintos gruposde interés. Diferentes agentes o profesionales intervienen en la presentación de la imagen corporativa, unos lo hacencon más propiedad y efectividad que otros. La investigación denominada “Caracterización del concepto de ImagenCorporativa que tienen las boutiques y los talleres de publicidad en Bucaramanga”, presenta un estudio comparativo sobre la comprensión que se tiene de dicho concepto en las entidades encargadas de asesorar a las empresas en suselementos de imagen, pues si bien se trata de darle a las organizaciones una apariencia destacada que logre diferenciarlasen el Mercado global -según propósitos del megaproyecto Santander Visión 20301-, proyección de la imagen no puedereducirse a un simple “maquillaje corporativo”. Se consideró entonces pertinente realizar una investigación en dichocampo de la Comunicación Organizacional, en Bucaramanga, ya que se han identificado ofertas inadecuadas dediseño y mercadeo de la imagen corporativa.Palabras clave: marketing, proyección de imagen, organizacional.
Introducción al superciudadano: la ciudadanía entre Nietzsche y el republicanismo
Authors: Mazuera Zuluaga Andrés Gustavo
Published: June 2020

La propuesta republicana sobre el papel que debe de asumir la ciudadanía en la construcción y la consolidación dela democracia a través de la participación activa en los escenarios políticos lleva a cuestionarse: ¿hasta qué punto esposible alcanzar la figura de un ciudadano responsable y comprometido con la vida política? La respuesta obligada a laanterior pregunta parece apuntar a la educación de un ciudadano republicano como método efectivo para hacer frentea las dificultades que afronta la democracia. Sin embargo, esta virtud cívica exigida lleva a pensar que el ciudadanoideal de la democracia se parece más a un superhombre que al ciudadano común. El ciudadano republicano es una especie de superciudadano. Por este motivo, la comprensión de este ciudadano, que se debate entre sus preocupacionesprivadas y las exigencias de la vida política, a partir de los obstáculos que encuentra Zarathustra cuando intenta enseñar una naturaleza sobrehumana, puede arrojar luces sobre el predicamento en el que se hallan los Estados democráticos cuando quieren educar un ciudadano con características más que humanas.
Holding Together, Coming Together or Putting Together? A [Re]examination on the Formation of Ethiopia’s Federation
Authors: Muluye Ketemaw Tiruneh
Published: June 2020

Federations are institutional and structural arrangements with the tenets of shared rule and self-rule. These federations may be formed through coming together, holding together or putting together processes. Both holding together and coming together federations are established through democratic bargain while putting together federation is imposed coercively by the winners. Hence, this article aims to situate Ethiopia in to one of these three variants through critical [re]examination of the transitional activities. The data were collected through interviews and document analysis. A qualitative analysis was employed to analyze the data. Accordingly, the paper argues that Ethiopia is a putting together federation because of the major flaws committed during the transition. Particularly, the absence of an organization that could represent Amhara during the Peace Conference, exclusion of the major political organizations from the conference and the aftermath processes as well as the inhuman and extrajudicial treatments against those who were explaining their discontent in the restructuring processes are some of the justification to level Ethiopia’s federation as putting together. Moreover, the electoral frauds that forced the major political parties to boycott the elections (the 1992 and 1994 elections) and the manipulation of the drafting and ratification processes of the constitution by TPLF/EPRDF can justify this position. Hence, it is recommended to restructure the federation through democratic bargaining for the putting nature of the federation is facing a legitimacy crisis due to the different questions rooted in the formation processes.
Organization of Oral Advertising and Agitation in the Years of the Great Patriotic War (On Materials of North Ossetia)
Authors: Bimbasov Ruslan G.
Published: June 2020

This author examines the activities of Soviet party-state bodies in the field of propaganda among the population in the North Ossetian Autonomous Soviet Socialist Republic (North Ossetia) during the Great Patriotic War. Propaganda is effective when its message is deeply rooted in the consciousness of the population group to which it is addressed. For this reason the media and the organizations of oral propaganda of North Ossetia sought to get the most accurate information on the particular group that was called upon to fulfill wartime tasks. The author used various types of sources, including documents from the Central State Archive of the Republic of North Ossetia that are here first introduced into scientific circulation. The paper identifies the directions of party-state bodies in organizing propaganda on the territory of the republic in 1941-1945, and it assesses the degree of their effectiveness. While the outbreak of the war led to an expansion of propaganda, there was an acute shortage of specialists in various fields of life, including in propaganda work among the civilian population. The paper reveals the main methods of forming the image of the enemy by propaganda bodies and the media. The author concludes that the activities of the propaganda apparatus in the republic during the War had a direct impact on public consciousness and contributed to the consolidation of the region's population in the fight against the enemy, and to overcoming the difficulties of the War years.
The Evolution of Ethnic Tradition Transfer among Belorussian Peasant Settlers in Siberia and Russia’s Far East from 1850 to the Present
Authors: Fedorov Roman Yu.
Published: June 2020

This article examines how the transfer of ethnic traditions among Belorussian peasant settlers in Asian Russia to their descendants has evolved since 1850. Based on field data collected from different generations of Belorussian settlers born during the 20th century, the study indicates that the mechanism of this transfer went through three very distinct phases. From the second half of the 19th century until the 1920s, the children of Belorussian settlers adopted the ethnic identity and traditions of their parents, much like their forefathers back home. During the Soviet era, i.e., from the early 1920s until the late 1980s, the state sought to replace Belorussian customs and conventions among the settlers children with its own homogenous, socialist modernity. After the USSRs collapse in 1991, the growing influence of mass media and more contemporary socio-cultural processes began to influence how ethnic traditions were transferred to the young. All three periods left their imprint on the outlook of the descendants of Belorussian settlers today. This is largely the result of the fact that practical knowledge and skills change more rapidly than deeper values and beliefs.

Prostate cancer (PC) remains an urgent public health problem, especially in developed countries. The use of immunohistochemical research methods in addition to the morphological classification of prostate adenocarcinomas allows a more accurate diagnosis and prognosis of the disease. The aim of the study is to identify isoforms of P53 using clones of mouse antibodies (D-07 and Y5; Epitomics, USA) in prostate cancer with different proliferative activity and the degree of malignancy. Materials and Methods: The work included surgical material for prostate resection and prostatectomy, as well as biopsy specimens (56 cases in total). An immunohistochemical study was carried out with the Ki-67 marker, as well as with mouse monoclonal antibodies (D-07 and Y5) to the P53 protein, interacting with its wild and mutant isoforms. The significance of the difference in the samples was determined using the Mann-Whitney U-test, correlation relationships were determined using the Spearman coefficient. Results: Expression of P53 upon interaction with antibodies D-07 and Y5 was determined in 56.3% and 39.6%, respectively. A statistically significant direct correlation was found between the severity of P53 expression when interacting with Y5 antibodies and the degree of tumor differentiation (rs = 0.567, p 0.05), as well as between the expression level of this protein and tumor proliferative activity (rs = 0.698, p 0.05). Conclusion: Antibodies of clone D-07, interacting with both wild and mutant isoforms of P53 protein, show positive expression in adenocarcinomas of all degrees. Expression of the mutant P53 protein is most pronounced in low-differentiated carcinomas and correlates with high proliferative activity of tumor cells, which may be associated with a loss in the induction of P53-dependent apoptosis.
Functional results of surgical treatment of retinal detachment
Authors: Ilyukhin O. E. , Frolov M. A. , Ignatenko K. V.
Published: June 2020

The article analyzes the state of patients visual acuity after successful surgical treatment of retinal detachment. On the basis of gathered data, it was concluded that in case of detachment of the macula only in 50% of cases it is possible to increase visual acuity to 0.4 and higher. Restoration of visual functions continues for at least 6 months after the operation and is determined by the restoration of the structure of the outer segments of the photoreceptor cells. During this time, it is advisable to conduct drug therapy aimed at normalizing blood flow and functional activity of the retina. Visual functions recovery continues for at least 6 months after the operation and is connected with the restored structure of the outer segments of the photoreceptor cells. Important prognostic factors of central vision restoration in the postoperative period are visual acuity before surgery, duration of existence and height of macular detachment. Data on which of the methods of surgical treatment of retinal detachment allows to achieve higher visual acuity are contradictory. There is practically no data on the comparison of the effect on visual acuity of scleral buckling and vitrectomy in the long-term period, in patients with phakic eyes and with artiphakia. On visual acuity after fitting detachment of the macula may affect macular edema, epiretinal membrane formation and retinal folds, and edema of the peripapillary optic nerve head, progressive deterioration of blood flow in the basin of the central retinal artery, short posterior ciliary arteries and ophthalmic artery. It is believed that these factors are significantly more pronounced after scleral buckling than after vitrectomy. Some indicators of optical coherence tomography correlate with visual acuity after surgical treatment of retinal detachment: the state of the articulation line of the external and internal segments of the photoreceptors, as well as the state of the external limiting membrane.

Authors: Mikhaylova S. V.
Published: June 2020

To characterize fitness health, defined as the state of the physical well-being of the body, due to the functional state, physical qualities and component composition of the body, assessment methods are needed. The purpose of the study : physiological justification of the choice of indicators for assessing the fitness of students health. Methods: the study was conducted according to the results of preventive examinations of 303 students 18-24 years old at the Health Center, including: anthropometry, bio-impedance research and assessment of physical fitness. Results. To assess fitness health, we used an index of the component composition of the body, which characterizes the ratio of components (fat and active cell mass, water content and basic metabolism), which ensures the flow of metabolic processes, maintaining nutritional status, shaping the nature of working capacity and the adaptive potential of the body. The body composition index has the greatest correlation with the level of fitness health. Assessment of physical fitness, necessary when choosing an adequate regime of power and aerobic load, was carried out according to motor tests included in the RWD complex. Using the index method (power index, Skibinskaya index, endurance coefficient), the functional state of the basic life support systems of the body involved in the implementation of motor activity was characterized. Conclusions. The application of the studied indicators for assessing fitness health has a physiological justification and is confirmed by the correlation analysis.

EMPLOYEE SHUTTLE BUS ROUTING PROBLEM
Authors: YALÇINDAĞ Semih
Published: June 2020

Recently, companies have started to use engineering techniques more than ever due to competitive market conditions, high costs, and limited budgets. To be able to reduce incurred costs and increase profitability, companies deeply analyze all the existing processes carefully. In this work, the Employee Shuttle Bus management process of an international company, which is located in Gebze, is considered, analyzed, and improved through mathematical modeling technique. Unified and Area-Based solution alternatives are developed by extending the mathematical formulation of the widely studied School Bus Routing Problem. Both proposed methods and the current situation of the company have been implemented on GAMS and solved by the CPLEX solver. It has been observed that proposed methods have provided significant cost reduction with respect to the current situation of the company. Among the newly developed methods, the Area-Based method has provided the best cost reduction amounts with less resource usage and shorter tour lengths.
60 years of the Serbo-Macedonian Unit concept: From Cadomian towards alpine tectonic frameworks
Authors: Spahic Darko , Gaudenyi Tivadar
Published: June 2020

The study represents a summary of the hitherto tectonic concepts revolving around a peri-Gondwanan fragment referred to as the Serbo- Macedonian Unit. The Serbo-Macedonian Unit as a gneiss-dominated basement segment is positioned in the proximity of the Baltican craton (peri-Moesian realm). This area represents a repository of the transferred broadly similar thus highly complex, elongated polycrystalline vestiges of the Pan-African inheritance. This peculiar far-travelled composite crustal fragment of north Gondwana is amalgamated on top of the Supragetic unit during the late Variscan peri-Moesian amalgamation. However, the original early Pa - leozoic tectonostratigraphic configuration of these three intimate green schistand medium- to high-grade gneiss-amphibolite basement vestiges (Serbo-Ma - cedonian/Supragetic and Getic) is further perplexed by the presence of poorly documented pre-Variscan (Ordovician?) lithospheric-scale event. The Pan-African to Lower Paleozoic subduction/magmatic arc stage led to the amalgamation, breakup and dispersal of a cluster of peri-Gondwanan continental and oceanic terranes. Breakup and dispersal from the northern shore of the Gondwanan active margin triggered the development of the Paleozoic deep-marine sedimentary cover (?Kucaj unit? or Getic unit). To make matter more complex, prior the Lower Paleozoic terrane agglomeration and sub - sequent dispersal, it appears that a Lower Paleozoic geodynamic linkage is additionally marked by the poorly investigated cross-lithospheric event. This event connects the outboard oceanic Supragetic/?Kucaj? succession with a segment of the former north Gondwanan protobasin (juvenile Serbo-Ma - cedonian Unit).

Authors: Gonca Guven , Hocaoglu Mehmet
Published: June 2020

Performance examinations of a dual-Diesel cycle engine in point of engine performance characteristics such as exergy efficiency, power and power density have been conducted. The effect of design parameters of the engine cycle such as intake temperature, intake pressure, piston friction coefficient, average piston velocity, engine revolution, stroke length, residual gas fraction, engine pressure ratio, engine temperature ratio, compression ratio, ratio of bore diameter to stroke length, and equivalence ratio, on the performance characteristics are evaluated by considering variable specific heats and irreversibilities resulting from exhaust output, heat transfer, incomplete combustion and friction. The results can provide substantial information researchers who study on dual-Diesel cycle engine design and manufacture.
Binary collisions and coalescence of droplets in low-pressure fuel injector
Authors: Ahmed Fatma , Kawahara Nobuyuki , Tomita Eiji
Published: June 2020

The phenomena of binary collisions and coalescence of droplets was investigated from experimental studies but still are missing from real applications such as from fuel injector. The main purpose of the current study is to investigate the phenomena of binary collisions and coalescence of droplets from a practical port fuel injector. To accomplish this, direct microscopic images are taken from high speed video camera coupled with a long-distance microscope and Barlow lens using the backlighting method. Experimental optimization of the spatial resolution and the depth -of -field of the long-distance microscope and Barlow lens are achieved. Experimental results from the direct microscopic images are compared with predictions from empirical equations for different collision regimes. Droplet sizes and velocities of experimental coalescence droplets from collisions are compared with the values predicted by the equations. The main results of this study are: The probability of collision and coalescence is very low in a port fuel injector. The tangential velocity components of small droplets play an essential role in shape deformation during collisions and coalescence of the droplets. The previous published empirical equations to calculate dimensionless parameters, the Weber number, the droplet diameter ratio, and impact parameter are applicable to the coalescence of droplets in a port fuel injector.
Analysis of temperature variations in fixed-bed columns using non-isothermal and non-equilibrium transport model
Authors: Zafar Shireen , Perveen Sadia , Cheema Asad , Qamar Shamsul
Published: June 2020

A non-isothermal and non-equilibrium two-component lumped kinetic model of fixed-bed column liquid chromatography is formulated with the linearized isotherm and solved analytically to study the influence of temperature variations on the process. The model equations constitute a system of convection-diffusion PDE for mass and energy balances in the bulk phase coupled with differential equations for mass and energy balances in the stationary phase. The analytical solutions are derived for Dirichlet boundary conditions by implementing the Laplace transformation, Tschirnhaus-Vieta approach, the linear decomposition technique and an elementary solution technique of ODE. An efficient and accurate numerical Laplace inversion technique is applied to bring back the solution in the actual time domain. In order to validate the derived analytical solutions for concentration and temperature fronts, the high resolution upwind finite volume scheme is applied to approximate the model equations numerically. Various case studies are carried out assuming realistic model parameters. The results obtained will be beneficial for interpreting mass and energy profiles in non-equilibrium and non-isothermal liquid chromatographic columns and provide deeper insight into the sensitivity of the separation process without performing costly and time-consuming laboratory experiments.
Outage performance evaluation of device-to-device system with energy harvesting relay
Authors: Simonovic Milos , Cvetkovic Aleksandra , Manojlovic Jelena , Nikolic Vlastimir
Published: June 2020

The development of Internet of Things devices as well as the increase of nodes in wireless networks, motivates the use of node?s cooperation for wireless system performance improvement. On the other hand, the power requirements of the increasing number of nodes leads to the need for new powering sources. In this paper we consider device-to-device relay-assisted system, where decode-and-forward relay is not equipped with its own power supply, but it harvests energy and uses it for the data transfer to the destination node. System performance is derived for the Fisher-Snedecor F composite fading channel model and energy harvesting protocol based on time-switching scheme. The closed-form approximate expression for the outage probability is derived, that corresponds to the exact results. The impact of the channel fading and shadowing parameters and time-switching factor of energy harvesting protocol on the system performances are investigated. Numerical results are confirmed by an independent simulation method.
Five Evidence-Based Lifestyle Habits People With Diabetes Can Use
Authors: Chacko Elsamma , Signore Christine
Published: June 2020

Several evidence-based lifestyle habits focusing on the composition, timing, and sequence of meals and on pre- and postmeal exercise can improve diabetes management. Consuming low-carbohydrate, balanced meals and eating most carbohydrates early in the day are helpful habits. Eating the protein and vegetable components of a meal first and consuming the carbohydrates 30 minutes later can moderate glucose levels. Postmeal glucose surges can be blunted without precipitating hypoglycemia with moderate exercise 30–60 minutes before the anticipated peak. Short-duration, high-intensity exercise could also be effective. Premeal exercise can improve insulin sensitivity but can also cause post-exertion glucose elevations. Moreover, high-intensity premeal exercise may precipitate delayed hypoglycemia in some people. Glycemia benefits can be enhanced by eating a light, balanced breakfast after premeal exercise.

Objective: Compare the risk of lactic acidosis hospitalization between
patients treated with metformin versus sulfonylurea following development of reduced
kidney function.

Research Design and Methods: This retrospective
cohort combined data from National Veterans Health Administration, Medicare,
Medicaid and National Death Index. New users of metformin or sulfonylurea were
followed from development of reduced kidney function (estimated Glomerular
Filtration Rate [eGFR] <60 ml/min or serum creatinine >1.4
[female] or 1.5 [male] mg/dL) through hospitalization for lactic acidosis,
death, lost to follow-up or study end. Lactic acidosis hospitalization was
defined as a composite of primary discharge diagnosis or laboratory-confirmed
lactic acidosis (lactic acid >2.5 mmol/L and either arterial blood pH
<7.35 or serum bicarbonate <19 mmol/L within 24 hours of admission).
We report the cause specific hazard of lactic acidosis hospitalization between
metformin and sulfonylurea from a propensity score matched weighted cohort, and
conduct additional competing risks analysis to account for treatment change and
death.

Results:
The weighted cohort included 24,542
metformin and 24,662 sulfonylurea users who developed reduced kidney function
(median age 70 years, median eGFR 55.8 ml/min/1.73m2). There were 4.18 [3.63, 4.81] versus 3.69 [3.19, 4.27] lactic
acidosis hospitalizations per 1,000 person-years among metformin and
sulfonylurea users, respectively (adjusted hazard ratio (aHR) 1.21 [0.99, 1.50]).
Results were consistent for both primary discharge diagnosis (aHR 1.11 [0.87,
1.44]) and laboratory-confirmed lactic acidosis (aHR 1.25 [0.92,1.70]).

Conclusions: Among
veterans with diabetes who developed reduced kidney function, occurrence of lactic
acidosis hospitalization was uncommon and not statistically different between patients
who continued metformin and sulfonylurea.

Objective This study aims to evaluate the association of energy
and macronutrients intake at dinner vs. breakfast with disease-specific and all-cause
mortality in people with diabetes.

Methods 4699 peoples
with diabetes who enrolled in the National Health and Nutrition Examination
Survey from 2003 to 2014 were recruited for this study. Energy and
macronutrients intake were measured by a 24h dietary-recall. The Differences(△) in energy and
macronutrients intake between dinner and breakfast (△=dinner minus
breakfast) were categorized into quintiles. Death
information was obtained from the National Death Index until 2015. Cox proportional
hazards regression models were developed to evaluate the survival relationship
between △
and diabetes, cardiovascular-disease (CVD) and all-cause mortality.

Results Of the 4699 participants,
913 deaths, including 269 deaths due to diabetes and 314 deaths due to CVD,
were documented. After adjusting for potential confounders, compared with
participants in the lowest quintile of Δ in terms of total energy and protein, participants
in the highest quintile were more likely to die due to diabetes (HRΔenergy=1.92,
99% CI:1.08-3.42; HRΔprotein=1.92, 99% CI:1.06-3.49) and CVD (HRΔenergy=1.69,
99% CI:1.02-2.80; HRΔprotein=1.96, 99% CI:1.14-3.39). The highest quintile
of Δ from total-fat was related with CVD mortality (HR=1.67, 99% CI: 1.01-2.76).
Isocalorically replacing 5% of total-energy at dinner with breakfast was
associated with 4% and 5% lower risk of diabetes (HR=0.96, 95% CI: 0.94-0.98)
and CVD (HR=0.95, 95% CI: 0.93-0.97) mortality.

Conclusions Higher intake
of energy, total-fat and protein from dinner than breakfast was associated with
greater diabetes, CVD and all-cause mortality in people with diabetes.

Authors: ARSLAN Necla , BELGİN Önder
Published: June 2020

Research and Development (R&D) and innovation have a significant impact on the competitiveness of countries. Science and Technology Parks (STPs) are an important component of R&D and innovation ecosystems of countries and they aim to increase the university-industry collaboration. This study addresses the efficiency analysis of STPs in Turkey using Data Envelopment Analysis (DEA). For this purpose, an input-oriented DEA model is used to obtain efficiency scores of STPs and 5 of 22 STPs are found to be efficient. After that, to examine the strong and weak areas of STPs six additional Data Envelopment Analysis (DEA) models are considered. According to these models, STPs exhibits lower performance in the efficiency of revenue and patents. Finally, STPs are clustered based on efficiency scores as Marketers, Researchers and Low-performers using K-means clustering and we made suggestions for each cluster. The motivation of this study is contributing to policies for increasing the performance and the impact of the STPs in Turkey.

Bu çalışmada, uranyum yakıtlı bir lazer sürücülü füzyon reaktöründe (LIFE) nötronik analiz ve bu reaktörün hidrojen üretim potansiyeli araştırılmıştır. Nötronik hesaplamalar MCNP nükleer kodu yardımıyla yapılmıştır. Nükleer yakıt olarak %10 uranyum dioksit (UO2), soğutucu olarak ise %90 natural lityum kullanılmıştır. Nötronik hesaplamalarda, trityum üretim oranı (TBR), enerji çoğaltım faktörü (M), yakıt yanma oranı (BU) ve fisil yakıt değişimleri elde edilmiştir. Ek olarak, reaktörün yüksek sıcaklıkta elektroliz (HTE) yöntemi ve kükürt-iyot (S-I) döngülü termokimyasal yöntem ile hidrojen üretim potansiyeli araştırılmıştır. Yapılan hesaplamalar sonucunda, reaktörde iyi bir nötronik performans elde edilmiş ve ayrıca hidrojen üretim metotlarından HTE metodunun S-I metoduna göre daha az güç kullanarak daha fazla hidrojen ürettiği gözlemlenmiştir.
Russinet i mindfulness: Erfarenhetsbaserad utbildning och praktik i religionsvetenskap
Authors: Enstedt Daniel
Published: June 2020

I den här artikeln argumenterar jag för praktikbaserade inslag i icke-konfessionell utbildning i religionsvetenskap. Det görs utifrån några konkreta exempel på religiös praktik som jag har utarbetat inom ramen för den undervisning som jag bedriver. Förslaget gäller inte övningar i varje situation eller sammanhang, och det indikerar inte heller att religiös praktik är det enda sättet att uppnå målen med religionsvetenskaplig utbildning. Det finns även etiska implikationer av att införa religiös praktik i en icke-konfessionell utbildning som jag menar bör tas i beaktande.
Jag argumenterar för att religiös praktik kan vara ett sätt att åstadkomma ett djupinriktat lärande och tillägna sig kunskap om religion som skiljer sig från andra typer av färdighetsträning som övas inom ramen för en icke-konfessionell utbildning. Religiös praktik i utbildningen kan även, menar jag, vara ett sätt att hantera de problem som det så kallade världsreligionsparadigmet är förknippat med, som har dominerat religionsvetenskaplig utbildning, läromedelsproduktion och kursplaner. Dessa problem handlar om försanttaganden, föreställningar och definitioner som präglar paradigmets religionsförståelse.
