Background

Monitoring is the mainstay of chronic kidney disease management in primary care; however, there is little evidence about the best way to do this.

Aim

To compare the effectiveness of estimated glomerular filtration rate (eGFR) derived from serum creatinine and serum cystatin C to predict renal function decline among those with a recent eGFR of 30–89 ml/min/1.73 m2.

Design and setting

Observational cohort study in UK primary care.

Method

Serum creatinine and serum cystatin C were both measured at seven study visits over 2 years in 750 patients aged ≥18 years with an eGFR of 30–89 ml/min/1.73 m2 within the previous year. The primary outcome was change in eGFR derived from serum creatinine or serum cystatin C between 6 and 24 months.

Results

Average change in eGFR was 0.51 ml/min/1.73 m2/year when estimated by serum creatinine and −2.35 ml/min/1.73 m2/year when estimated by serum cystatin C. The c-statistic for predicting renal decline using serum creatininederived eGFR was 0.495 (95% confidence interval [CI] = 0.471 to 0.519). The equivalent c-statistic using serum cystatin C-derived eGFR was 0.497 (95% CI = 0.468 to 0.525). Similar results were obtained when restricting analyses to those aged ≥75 or <75 years, or with eGFR ≥60 ml/min/1.73 m2. In those with eGFR <60 ml/min/1.73 m2, serum cystatin C-derived eGFR was more predictive than serum creatinine-derived eGFR for future decline in kidney function.

Conclusion

In the primary analysis neither eGFR estimated from serum creatinine nor from serum cystatin C predicted future change in kidney function, partly due to small changes during 2 years. In some secondary analyses there was a suggestion that serum cystatin C was a more useful biomarker to estimate eGFR, especially in those with a baseline eGFR <60 ml/min/1.73 m2.

Key Points

Frailty prevalence varies for the Frailty Phenotype, a frailty index, and the Clinical Frailty Scale in transplant candidates.

Agreement between these measures for determining frailty status was variable, suggesting they measure different aspects of frailty.

The frailty index and the Clinical Frailty Scale were associated with a shorter time to death or waitlist withdrawal in an unadjusted analysis.

Background

Comparisons between frailty assessment tools for waitlist candidates are a recognized priority area for kidney transplantation. We compared the prevalence of frailty using three established tools in a cohort of waitlist candidates.

Methods

Waitlist candidates were prospectively enrolled from 2016 to 2020 across five centers. Frailty was measured using the Frailty Phenotype (FP), a 37-variable frailty index (FI), and the Clinical Frailty Scale (CFS). The FI and CFS were dichotomized using established cutoffs. Agreement was compared using κ coefficients. Area under the receiver operating characteristic (ROC) curves were generated to compare the FI and CFS (treated as continuous measures) with the FP. Unadjusted associations between each frailty measure and time to death or waitlist withdrawal were determined using an unadjusted Cox proportional hazards model.

Results

Of 542 enrolled patients, 64% were male, 80% were White, and the mean age was 54±14 years. The prevalence of frailty by the FP was 16%. The mean FI score was 0.23±0.14, and the prevalence of frailty was 38% (score of ≥0.25). The median CFS score was three (IQR, 2–3), and the prevalence was 15% (score of ≥4). The κ values comparing the FP with the FI (0.44) and CFS (0.27) showed fair to moderate agreement. The area under the ROC curves for the FP and FI/CFS were 0.86 (good) and 0.69 (poor), respectively. Frailty by the CFS (HR, 2.10; 95% CI, 1.04 to 4.24) and FI (HR, 1.79; 95% CI, 1.00 to 3.21) was associated with death or permanent withdrawal. The association between frailty by the FP and death/withdrawal was not statistically significant (HR, 1.78; 95% CI, 0.79 to 3.71).

Conclusion

Frailty prevalence varies by the measurement tool used, and agreement between these measurements is fair to moderate. This has implications for determining the optimal frailty screening tool for use in those being evaluated for kidney transplant.

Authors: Akdemir Ahmet Selçuk
Published: May 2021

This study investigated the efficiency of self-editing to reduce language errors of nurse educators. To achieve this, a checklist was created and 15 nurse educators from three different universities were educated on how to self-edit throughout 10 weeks. Data were obtained through 3 editing tasks before the 10-week education course and 3 editing tasks after the course. The Wilcox on test analysed pre-tests and post-tests, and found a statistically significant difference in terms of noticing the language errors through self-editing. This study suggests nurse educators use the checklist before submitting a manuscript. Also, this study concludes that self-editing is an efficient way of revealing language errors and increasing accuracy in English writing of nurse educators.

Authors: Barin Muzaffer , Eyerci Aysel
Published: May 2021

This study was designed with an aim to investigate the relationship between willingness to communicate (WTC) and learner autonomy (LA) in EFL settings at a Turkish university context. The primary purpose of the study was to reveal the possible statistically significant relationship between L2 WTC and learner autonomy of EFL learners in the classroom setting. The study was based on a mixed-methods research design. 211 students majoring at the Department of English Language and Literature of a state university in Turkey participated in the study. The instruments which were used to collect data were a willingness to communicate scale, a learner autonomy scale, and classroom observation. The results revealed that there was a moderate but significant relationship between EFL learners’ WTC and LA. The autonomy levels of the EFL learners had a predictive role in their L2 WTC. The difference between the self-reported L2 WTC and the behavioural L2 WTC of the Turkish EFL students was higher when the autonomy level of the students was lower. Based on the results, implications for enhancing L2 WTC of EFL learners are discussed.

Today, it is known that rapidly developing industrialization and urbanization seriously threaten the future of humanity. This situation brings to mind the concept of ‘sustainable development’. The aim of this study is to determine the “Sustainable Development’ awareness of prospective teachers in different branches. Survay method was used in the study. The sample of the study consists of 175 pre-service teachers who study in five different branches of the Faculty of Education of a university located in the Eastern Anatolia region in the fall semester of 2018-2019 academic year. 35 students from each of the departments of Science Teaching, Primary School Teaching, Elementary Mathematics Teaching, Preschool Teaching and Social Sciences Teaching participated in the study. The data of the study were collected with a 5-point Likert scale type of 21 items. Prior to this study, the pilot study was conducted with 121 pre-service teachers from different branches of the sample and the cronbach’s Alpha reliability coefficient was found 0,81. From the parametric tests One way ANOVA and Tukey tests were used to analyze the data obtained from the study. As a result of the study, it was determined that the highest mean score in terms of sustainable development awareness belongs to the prospective teachers studying in the Science Teaching Department and the lowest mean score belongs to the prospective teachers studying in the Mathematics Teaching Department. In the study, it was found that there was no statistically significant difference between the sustainable development awareness of Science, Classroom and Social Studies teacher candidates. Adding courses related to sustainable development to the pre-service teachers’ curriculum are among the suggestions of the study.

K-Bakery is a bakery located in Bandar Lampung City, Lampung. K-Bakery produces various types of bread, namely brown bread, nuts, greentea, mocha, and tiramisu bread which involve various raw material resources. Unstable market demand creates obstacles for K-Bakery in formulating the number of each type of bread to be produced so as to produce maximum profit. However, in determining the amount of production must pay attention to the limited supply of raw materials. In this case, there is a need for production planning so that all available resources can be used optimally and produce a combination of production that provides maximum profit. One way to solve this problem is to optimize production using a fuzzy linear program with a tolerance of 10% as the capability of K-Bakery. The use of the fuzzy linear program generates greater profits than the usual linear program, the profit obtained is Rp. 11.247.972,1708by producing 320 chocolate breads, 449,75 peanut breads, 365,667 greentea breads, 250 moka breads fruit, 449,925 srikaya bread, and 499,975 tiramisu breads. In addition, the value of l = 0,5 is obtained, or in other words, the maximum addition of each raw material is 50% of the available safety stock.

Authors: Putri Nabila Nurita , Muliawati Triyana
Published: May 2021

COVID-19 is an infectious disease caused by a new type of corona virus, beta coronavirus. The spread of COVID-19 can occur through human interactions. On March 9, 2020 the WHO (World Health Organization) officially declared COVID-19 a pandemic. This means that COVID-19 has spread widely in the world. Until now, there has not been found a drug to treat COVID-19. So, it is necessary to predict when the COVID-19 pandemic will end. This study discusses the Markov chain method in predicting the status of COVID-19 patients in Indonesia. The prediction of the number of people who are positive for COVID-19, recovered, and die can be one of the government's bases for determining when the large-scale social restrictions (PSBB) will end. The results of the study stated that the COVID-19 pandemic in Indonesia would end at the end of 2020. On December 5, 2020 there were no more people infected with COVID-19 with a cure rate of 29.815% of patients with COVID-19 and a death rate of 3, 5933%.

Authors:   , Machetti Natalia Elisabet
Published: May 2021

La región pampeana argentina padece acidificación en algunos suelos por su historia productiva y tecnología aplicada en las últimas décadas, derivando en consecuencias negativas sobre algunos cultivos de cosecha. Experiencias de encalado realizadas en las provincias de Buenos Aires y Santa Fe mostraron efectos positivos sobre el aumento de pH de suelo y la saturación de bases teniendo mejorando las propiedades físicas y el rendimiento. El objetivo de esta tesis fue evaluar en tres suelos del ámbito templado argentino (Hapludol, Argiudol y Paleudol) la incidencia de diferentes prácticas de encalado sobre propiedades físicas, físico-químicas y químicas, sobre el rendimiento de especies de interés regional, y sobre la tolerancia generada ante procesos de compactación. A partir de mediciones a campo y determinaciones en laboratorio, se analizó el impacto de diferentes dosis y combinaciones de enmiendas en el tiempo sobre el complejo de cambio y cationes, componentes orgánicos y propiedades hidrofísicas relacionadas con la arquitectura edáfica. Se determinó el rendimiento de soja y alfalfa para establecer una relación con las variables analizadas. En los tres suelos el pH aumentó conforme a las dosis y dichos efectos se incrementaron con el tiempo. En el Hapludol la menor dosis de enmienda produjo un aumento en la capacidad de intercambio catiónico asociado a la materia orgánica, generando mejoras en las variables físicas. En el Argiudol y Paleudol se observaron mejoras en las propiedades hidrofísicas y estructurales, vinculadas a incrementos de cationes intercambiables, con mayores dosis de enmiendas que en el Hapludol. El rendimiento de alfalfa en el Hapludol se incrementó con todas las dosis de dolomita y yeso. El rendimiento de soja en el Argiudol y Paleudol no se modificó con la adición de enmienda. Los beneficios que generaron las enmiendas en el Hapludol le confirieron tolerancia a los procesos de compactación a la estructura del suelo y al rendimiento.

Authors: Maiti Krishnendu , Kumar Kundan , Pal Dilip Kumar
Published: May 2021

OBJECTIVE: To compare the impact of catheter size 14 French vs 12 French on quality of life of patients using Clean intermittent selfcatheterization.
SUBJECTInclusion criteria patients using CISC for neurogenic (DSD) bladder, hypo contractile bladder.
Exclusion criteria patient with urethral stricture, history of urethral, bladder, or prostate surgery, pediatric patients.
METHODS: It was a comparative, observational, study which comprised of total 40 patients diagnosed with neurogenic bladder (detrusor
sphincter dyssynergia), hypo contractile bladder, out of which 20 patients were given 12french catheter and 20 patients were given 14 French
catheters as per coin randomization method. The patients were assessed for quality of life by using WHO QoL-BREF. T- test was utilised to
compare the mean. p<o.05 was taken to be statistically signicant.
RESULTS: In physical domain the mean score was higher in patients using 12 French catheter (56.01) compared with patients using 14 French
catheter (55.1) but difference was statistically insignicant with p-value (0.688). In Psychological domain the mean score was higher in patients
using 12 French catheters (63.90) compared with patients using 14 French catheters (63.30) with p-value (0.793). In Social relationships domain
the mean score was higher in patients using 14 French catheters (62.20) compared with patients using 12 French catheters (61.55) but difference
was statistically insignicant with p-value (0.855). similarly in the social relationships domain the mean score was higher in patients using 14
French catheter (58.65) compared with patients using 12 French catheter (58.53) with p-value 0.935.
CONCLUSION: Higher score in physical and psychological domain implies less pain, greater treatment compliance and improving the patient's
QoL, but higher score observed in physical and psychological domain was statistically insignicant. Based on above study we concluded that there
was no signicant difference in quality of life of patients using 12 French or 14 French for CISC.
WITH REGARDS TO THE CLINICO-FUNCTIONAL OUTCOMES, IN BETWEEN FQPP OR BDSF TECHNIQUE, WHICH IS SUPERIOR, AS A CANCELLOUS SCREW FIXATION OPTION, FOR FRACTURE NECK OF FEMUR.
Authors: S Vijayaselvan , K Venkatachalam
Published: May 2021

Fracture Neck of Femur are common and one among the most challenging Orthopaedic trauma cases. Many a factors like age, time elapsed after
occurrence of injury, presence of other musculo-skeletal trauma and presence of other co-morbid conditions, are all to be taken into account, before
embarking on any surgical intervention. Given the precarious blood supply of the femoral head, AVN of the femoral head is a signicant
complication in the displaced fractures. Among the various classication systems available, the Garden classication is still in vogue, as
highlighted by Guyton J.L et al; (1). The purpose of this prospective study, is to establish the superiority or otherwise of the 'Four Quadrant
Peripheral Parallel (FQPP) Screw Fixation” technique, over the “Biplanar Double Support Screw Fixation (BDSF)” technique, when opting for
multiple percutaneous cancellous screw xation, for fracture neck of femur. The age group in our study included patients from 26 years to 55 years
and had a total of 18 patients, who were recruited in between March 2018 to February 2020. Of these 18 patients, 9 patients were treated by the
FQPP technique and another 9 patients by the BDSF technique. All cases were followed-up for at least 1 year (range: 12 to 35 months, mean 18
months). Evaluation was done by Harris Hip Score (HHS) (2). In the FQPP group, 55.56% (n=5) patients had good to excellent results, 22.22%
(n=2) patients had fair and 22.22% (n=2) patients had poor outcomes. In the BDSF group 66.67% (n=6) patients had good to excellent results,
22.22% (n=2) patients had fair and 11.11% (n=1) patient had poor outcome. Thus, the results were only just marginally better for the BDSF group,
in comparison to the FQPP group and hence, no substantial deductions could be made favoring the superiority of one xation type over the other.

A Índia, lar do pior surto de Covid-19 em andamento no mundo, relatou mais de 17,6 milhões de casos desde o início da pandemia, no ano passado. Mas o número real, temem os especialistas, pode ser até 30 vezes maior — o que significa mais de meio bilhão de casos.  As mortes, que oficialmente estão na casa das 200 mil, também estão subnotificadas e o número real pode ser de 400 mil ou de quase 1 milhão no pior cenário, segundo um estudo da Universidade de Michigan, nos Estados Unidos.
When a Canadian is not a Canadian: marginalization of IMGs in the CaRMS match
Authors: MacFarlane Malcolm M
Published: May 2021

This paper explores the marginalization experienced by International Medical Graduates (IMGs) in the Canadian Residency Matching Service (CaRMS) Match. This marginalization occurs despite all IMGs being Canadian citizens or permanent residents, and having objectively demonstrated competence equivalent to that expected of a graduate of a Canadian medical School through examinations such as the MCCQE1 and the National Assessment Collaboration OSCE. This paper explores how the current CaRMS Match works, evidence of marginalization, and ethnicity and human rights implications of the current CaRMS system. A brief history of post graduate medical education and the residency selection process is provided along with a brief legal analysis of authority for making CaRMS eligibility decisions. Current CaRMS practices are situated in the context of Provincial fairness legislation, and rationalizations and rationales for the current CaRMS system are explored. The paper examines objective indicators of IMG competence, as well as relevant legislation regarding international credential recognition and labour mobility. The issues are placed in the context of current immigration and education policies and best practices. An international perspective is provided through comparison with the United States National Residency Matching Program. Suggestions are offered for changes to the current CaRMS system to bring the process more in line with legislation and current Canadian value systems, such that “A Canadian is a Canadian.”

In this paper we construct blending surfaces using the univariate Bernstein operator. The surfaces have the properties that they stay on a curve (the border of the surfaces domain) and have a fixed height in a point from the domain. The surfaces are generated using a curve network, instead of the control points from the case of classical Bezier surfaces. We study the monotonicity and we give conditions to obtain concave surfaces.

REFLECTIONS ABOUT THE SOURCE OF POWER IN THE RUSSIAN FEDERATION
Authors: Vasiliev S. A.
Published: May 2021

According to Art. 3 of the Constitution of the Russian Federation, the only source of power in the Russian Federation is its multinational people. However, if you look at the meaning of the word «source», it turns out that in practice the situation is somewhat different. Power as such, and even more so, imperious decisions come much more often from completely different entities. The people are a kind of dominant force, non-verbally affecting those who make key decisions in society. At the same time, it is difficult for the latter to enter into a direct dialogue with the multinational people, therefore, the constitutional source often yields its quo status. This work is devoted to the interpretation of this thesis using the theory of correlation of subjects of law to obtain objective conclusions based on normative legal regulation and literary sources.

Authors: Anhar Muh , Polonia Betti Ses Eka
Published: May 2021

Metal connection due to heat with or without the influence of pressure or metallurgical bonds caused by attractive forces between atoms. DIN (Deutsche Industrie Normen) state that metallurgical bonding of metal or guide metal joints in a melted or liquid state. This study aims to determine the effect of limestone powder and gypsum as an insulating medium in SMAW (Shielded metal arc welding) welding. This study using experimental methods with SMAW welding. Welding metal cooled with limestone media has a harder hardness than gypsum and air media, which is limestone has a thermal conductivity value of 3.897 W / mºC. In comparison, gypsum has a thermal conductivity value of 1.39 W/mºC, and air has a thermal conductivity value of 0.023 J/msºC, so limestone is a better insulator than gypsum and air. The greater the conductivity value of the object, the better the thermal conductivity of the metal and the more complicated the weld metal and the lower the thermal conductivity value, the softer the metal hardness, limestone has a thermal conductivity value of 3.897 W / mºC while gypsum has a thermal conductivity value of 1, 39 W / mºC and air have a thermal conductivity value of 0.023 J / msºC, proving that the lower the conductivity value, the hardness of the weld metal is getting softer, but in the HAZ section it proves that the lower the conductivity value, the more complex the hardness in the HAZ section.
