A 6.6-nA 3.6-nW CMOS Current Reference with 0.4-V Supply Voltage
Authors: Mahmoudi Azad
Published: November 2022

This paper presents an all-MOSFET nano-ampere (nA) current reference with a wide operating temperature range able to operate at a supply voltage as low as 0.4 V for ultra-low power applications. The temperature-compensated current is generated by combining two currents with opposite temperature coefficients (TCs) which are derived from two NMOS transistors biased with different complementary-to-absolute-temperature (CTAT) gate voltages. Self-biased self-cascode MOSFET (SBSCM) stages operating in the subthreshold region are utilized as the slope-adjustable linear CTAT voltage generators to achieve both low-power and low-voltage operation. Designed in a 130 nm CMOS process with an active area of 0.0021 mm2, the proposed current reference achieves an average untrimmed TC of 308 ppm/°C over − 40°C to 120°C while generating an output reference current of 6.6 nA. Post simulation results show that the power consumption is only 3.68 nW at the minimum supply voltage at room temperature.

Authors: Gunduz-Meric Gamze
Published: November 2022

KIT-6 silicas were synthesized using pluronic P123 as surfactant and n-butanol as co-solvent in mild acidic condition. Different amounts of Zr (zirconium) were loaded to la3d mesoporous silica KIT-6. The syntheses were performed by hydrothermal method and the effect of metal on KIT-6 was investigated by SEM, TEM, FT-IR, NH3-TPD, H2-TPR, ICP-OES, N2 adsorption-desorption and XRD methods. The results showed that Zr ions were well incorporated into the KIT-6 silica. Zr has also effective and excellent performance for H2O2 decomposition reaction. The results also showed that Zr based KIT-6 catalysts were stable and reusability materials over H2O2 decomposition tests. The all catalysts presented mesoporous structure with BET results (~ 768 m2/g surface area) and high activity (~ 0.91) at mild conditions. H2O2 is an effective and environmentally friendly material and many studies were carried out to develop new and efficient materials in recent years. Mesoporous silicas especially KIT-6 is one of them but there are few studies about it and its derivatives.
Role of Autonomous Adaptation to Climate Change in Agriculture: A Survey-Based Analysis of Bihar, India
Authors: Das Saheli , Mehra Meeta Keswani , Paulson Jones
Published: November 2022

Climate change is having adverse implications for agricultural yields in India, especially in Bihar. Bihar is also less resilient to climate change requiring climate adaptation. Within adaptation, it is important to understand the channels of autonomous adaptation besides planned adaptation. So far, most studies have had the focus on technology-based planned adaptation, while autonomous adaptation has gained eminence for sustainability in agriculture. This research fills the gap to understand the role of autonomous adaptation – through channels of inherent ability and community networks – on agricultural productivity in case of paddy and wheat crops. We use a mix of quantitative perception analysis and survey econometric methods to delineate the role of these two channels. The survey of farmers is based on stratified random sampling for two districts of Bihar, belonging to different agro-climatic zones: Gaya (drought-prone) and Purnia (flood-prone). Our research finds that farming communities are discerning about climate change and rely on adaptation, through planned and autonomous channels. The effectiveness of planned adaptation is rather weak in both districts. The main empirical finding is that ancestral knowledge and community networks have positive impacts on paddy and wheat yields. However, results differ for types of community networks. Formal community networks boost crop yields, while informal community networks dampen paddy yields, but improve wheat yields in both districts.
Inexact Floating-Point Multiplication Using Vedic Algorithm
Authors: Priya S. Roobini , Ranjan P. Vanaja
Published: November 2022

This paper discusses on Vedic based floating point multiplication. The computations with integers representing very big or tiny numbers is cumbersome due to power aware designs required in IC designs. A good way to express integer values is using the IEEE 754 floating point encoding. DSP applications that use floating point numbers have a wide dynamic range of sophisticated computational processes that call for imprecise calculation techniques. This article describes the implementation and design of the Vedic multiplication and exact floating-point adder-based IEEE 754 channelized floating-point multiplier. The concepts in Vedic mathematics can be meritoriously used to improve logical sequences for implementing computational blocks in system on chip designs. Specific Vedic Sutras are discussed in this paper to implement and create the channelized floating-point multiplier according to IEEE 754. The multiplier's inputs are presented in IEEE 754 32-bit format. For mantissa multiplication, it uses the Urdhva Triyakbhyam sutra. Cases of underflow and overflow are handled through effective designs, to support design of pSoCs with power awareness.
Intraseasonal variations in winter surface air temperature over China and its prediction skill in ECMWF System5
Authors: Zheng Ting , Zheng Zhihai , Feng Guolin , Zhi Rong , Zhao Yuheng
Published: November 2022

Based on the daily average temperature data of 2374 stations in China from 1993 to 2019 and the monthly average temperature data of ECMWF System5 in winter, this paper analyses the intraseasonal variations of winter surface air temperature (SAT) over China from 1993 to 2019 by using seasonal empirical orthogonal function decomposition (S-EOF) and the prediction skill differences of the first three dominant modes in ECMWF System5. The first mode (S-EOF1) is characterized by out-of-phase changes in SAT anomalies (SATA) between December and January. Both the Siberian high (SH) and the central Pacific El Niño-Southern Oscillation (CP ENSO) can impact S-EOF1. The second mode (S-EOF2) is characterized by consistency in warm anomalies over the Northeast and Qinghai-Tibet Plateau’s variation, while the other areas are characterized by the out-of-phase change in SATA. S-EOF2 is closely related to Arctic Oscillation (AO). The third mode is characterized by alternating changes over three months in winter, which is related to the Pacific meridional mode (PMM) and the North Atlantic SST tripole (NAT). Comparing the ECMWF System5 prediction skill for the first three leading modes for the intraseasonal variations in winter SAT, the prediction skill is not high. The model did not predict the extent of warm anomalies and the intraseasonal fluctuation in S-EOF1, which may be due to the poor prediction skills for the range and intensity of the CP ENSO and the SH. The second mode has the highest prediction skill among the three modes. For the prediction skill of AO is good. The model can capture the intraseasonal reverse SATA between December and January but did not capture the reverse SATAs between January and February. Because the model does not predict obvious PMM and NAT well.

Gut microbiota has been identified as a unique endocrine organ that linked to the development of cardiovascular disease and other illnesses that deteriorated in overweight or obese postmenopausal women. The object of this systematic review and meta-analysis was to assess the effects of the oral supplementation with probiotics for overweight or obese postmenopausal women. We made a systematic search for randomized controlled trials (RCTs) from published to April 2022 in MEDLINE, EMBASE, Cochrane library, Web of science and ClinicalTrials.gov. The risks of bias in individual studies was assessed with the Cochrane risk of bias tool for randomized trials (RoB 2.0). Two reviewers independently selected studies and collected data. There were 6 studies came from 5 RCTs included in this systematic review. Compared with placebo, probiotics supplementation group had reductions in insulin (MD -4.20 IU/L (95% CI -8.11 to -0.30 IU/L), I2 = 54%) and HOMA-IR (MD -1.25 (95% CI -2.49 to -0.01), I2 = 50%). It also showed the improvements in body adiposity, lipid profile and inflammation, but they were non-significant. In addition to body adiposity and cardiovascular risk markers, there was one trail showed administration of probiotics also had an effect on iron metabolism. In conclusion, probiotics have a potential beneficial for glucose metabolism in overweight or obese postmenopausal women, but the number of current studies is small, the results need to be interpreted with caution and explained by more studies in the future.
ResTr: A Joint Framework for Retinal Vein Occlusion Image Classification
Authors: Wang Xiaochen
Published: November 2022

The classification method based on convolutional neural network can improve the performance of the pattern recognition system by automatically extracting and self-learning features. At present, the conventional image classification network, including the network method designed in this paper, directly uses the common depth convolution network to directly extract and classify features. Therefore, the core of optimizing the experimental results is how to better extract the features in the image, that is, to extract more advanced and richer features. The advantage of Transformer is to capture the global context information in the way of attention, so as to establish a long-distance dependence on the target, so as to extract more powerful features.

Background: Chronic obstructive pulmonary disease (COPD) is characterized by irreversible lung tissue damage. Novel regenerative strategies are urgently awaited. Cultured mesenchymal stem/stromal cells (MSCs) have shown promising results in experimental models of COPD, but differences between sources may impact on their potential use in therapeutic strategies in patients.
Aim:To assess the transcriptome of lung-derived MSCs (LMSCs), bone marrow-derived MSCs (BM-MSC) and adipose-derived MSCs (AD-MSCs) from COPD patients and non-COPD controls.
Methods: We studied differences in gene expression profiles between the MSC-subtypes, as well as between COPD and control using RNA sequencing (RNA-seq).
Results: We show that besides heterogeneity between donors, MSCs from different sources have strongly divergent gene signatures. The growth factors FGF10 and HGF were predominantly expressed in LMSCs. MSCs from all sources displayed altered expression profiles in COPD, with most pronounced significantly up- and downregulated genes in MSCs from adipose tissue. Pathway analysis revealed that the most differentially expressed genes in COPD-derived AD-MSCs are involved in extracellular matrix (ECM) binding and expression. In LMSCs, the gene that differed most strongly between COPD and control was CSGALNACT1, an ECM modulating gene.
Conclusion:Autologous MSCs from COPD patients display abnormalities with respect to their transcriptome, which were surprisingly most profound in MSCs from extrapulmonary sources. LMSCs may be optimally equipped for lung tissue repair because of the expression of specific growth factor genes.

We report the successful use of combination therapy with two direct acting antivirals for treatment of chronic COVID-19. An immunocompromised 60 year old male with persistent SARS-CoV-2 infection over 4 months had chronic, progressive COVID-19 requiring mechanical ventilation. After failing monotherapy with two antivirals and neutralising monoclonal antibodies, he was treated with a 10 day course of intravenous remdesivir and crushed nirmatrelvir/ritonavir (Paxlovid) administered through a nasogastric tube. Following treatment, SARS-CoV-2 RNA became undetectable, with resolution of supplemental oxygen requirement and acute inflammatory changes on computed tomography. This case demonstrates potential synergy between remdesivir and nirmatrelvir/ritonavir in treating persistent, symptomatic SARS-CoV-2 infection.

Published: November 2022

Background:

Breast cancer (BC) is considered the most malignant and central cancer-related death among women worldwide. There is an essential need to discover new methods for developing noninvasive and low-cost diagnoses. The present study examines the expression of KCNJ3 which acts as a biomarker for detecting BC in the saliva of BC patients compared to controls.

Methods:

The mRNA expression level of KCNJ3 has been evaluated. Forty-three unstimulated whole saliva samples from BC patients and forty-three salivary samples from healthy controls were collected. The mRNA level was measured using quantitative real-time polymerase chain reaction (qRT-PCR). Furthermore, the protein-protein interaction network in which KCNJ3 is involved was obtained. In silico analysis was applied to predict the possible molecular mechanisms of KCNJ3 in BC development.

Results:

Differentially expressed KCNJ3 was statistically significant between BC patients and controls (p<0.001). The sensitivity and specificity of KCNJ3 mRNA in BC detection were 76.74% and 94.95%, respectively. Receiver operating characteristic (ROC) curve analysis of KCNJ3 mRNA revealed that Area under the curve (AUC) was 0.923 (95% Confidence Interval (CI): 0.866-0.979). AUCs of ROC curve analysis were 0.743 (95% CI: 0.536-0.951), 0.685 (95% CI: 0.445-0.925), and 0.583(95% CI: 0.343-0.823) for differentiation stage I from stage III, stage I to stage II and finally stage II from stage III, respectively. Furthermore, the GABAergic synapse signaling pathway was suggested as a potential pathway involved in BC development.

Conclusion:

Salivary levels of KCNJ3 could be considered a potential diagnostic biomarker with high sensitivity and specificity for BC detection.

Published: November 2022

Organic compounds are one of the most severe pollutants occurring in the environment. Hence, it is important to remove these compounds from the environment through remediation processes such as photocatalysis. The present study investigated the photocatalytic degradation of p-nitrophenol (NP) and phenol red (PR) using a cerium oxide-titanium oxide nanocomposite (CeO2-TiO2nc) under UV light. CeO2-TiO2nc was synthesized using the co-precipitation method. An X-ray diffraction (XRD) analysis confirmed the phase purity of the material. A UV-Vis absorption study revealed a broad peak in the 250–310 nm region. The photocatalytic study was performed under three irradiation conditions: no light, visible light (λ > 400 nm), and UV light (λ < 400 nm). The maximum degradation percentage for NP and PR was 97.3% and 99.8%, respectively, with the reaction rate constant (k) of 0.42 and 0.54, respectively. This is the first study to utilize the synergistic effects of TiO2 and CeO2 for degrading NP and PR. Over 97% degradation was achieved for both the compounds in 80 min; this result shows the high photocatalytic activity of CeO2-TiO2nc. Thus, CeO2-TiO2nc can be used as a cost-effective adsorbent with a high capacity to degrade harmful organic compounds.
Importance of Patient Involvement in Creating Content for eHealth Interventions: Qualitative Case Report in Orthopedics
Authors: Timmers Thomas , van der Weegen Walter , Janssen Loes , Kremer Jan , Kool Rudolf Bertijn
Published: November 2022

Background

In many industries, collaboration with end users is a standard practice when developing or improving a product or service. This process aims for a much better understanding of who the end user is and how the product or service could be of added value to them. Although patient (end user) involvement in the development of eHealth apps is increasing, this involvement has mainly focused on the design, functionalities, usability, and readability of its content thus far. Although this is very important, it does not ensure that the content provided aligns with patients’ priorities.

Objective

In this study, we aimed to explore the added value of patient involvement in developing the content for an eHealth app. By comparing the findings from this study with the existing app, we aimed to identify the additional informational needs of patients. In addition, we aimed to help improve the content of apps that are already available for patients with knee replacements, including the app our group studied in 2019.

Methods

Patients from a large Dutch orthopedic clinic participated in semistructured one-on-one interviews and a focus group session. All the patients had undergone knee replacement surgery in the months before the interviews, had used the app, and were therefore capable of discussing what information they missed or wished for before and after the surgery. The output was inductively organized into larger themes and an overview of suggestions for improvement.

Results

The interviews and focus group session with 11 patients identified 6 major themes and 30 suggestions for improvement, ranging from information for better management of expectations to various practical needs during each stage of the treatment. The outcomes were discussed with the medical staff for learning purposes and properly translated into an improved version of the app’s content.

Conclusions

In this study, patients identified many suggestions for improvement, demonstrating the added value of involving patients when creating the content of eHealth interventions. In addition, our study demonstrates that a relatively small group of patients can contribute to improving an app’s content from the patient’s perspective. Given the growing emphasis on patients’ self-management, it is crucial that the information they receive is not only relevant from a health care provider’s perspective but also aligns with what really matters to patients.

Provider interacting eHealth behaviors: trends, predictors, and differences by subpopulations (Preprint)
Authors: McKeown Lisa , Hong Y. Alicia , Kreps Gary L. , Xue Hong
Published: November 2022

BACKGROUND

Patient-centered communication (PCC) and provider interacting eHealth behaviors (PIEB) play important roles in healthcare quality and patient-centered care. PIEB are the provider-facing eHealth behaviors that communicate with healthcare providers or the healthcare system, for example, communicating via email with a doctor, looking up test results, and making appointments online.

OBJECTIVE

The purpose of this study was to comprehensively examine PIEB and its association with PCC. We hypothesized that PIEB increased from 2017 to 2020, patients with higher levels of PCC were more likely to engage in total, direct, and indirect PIEB, and that there are differences in PIEB by subpopulation when controlling for PCC.

METHODS

We used nationally representative survey data from the 2017, 2019, and 2020 Health Information National Trends Study (HINTS). We conducted trend and multivariate regression analyses to understand changes in the relationships between PCC and PIEB, as well as to identify any differences in PIEB among key sociodemographic groups.

RESULTS

PIEB increased in recent years, with the largest increases reported by participants who used email or the internet to communicate with a doctor or a doctor’s office from 38.56% to 53.44%. In 2020, participants who experienced more PCC had two times higher odds of engaging in PIEB (aOR=1.97, 95% CI 1.35-2.87). Adults who were older, had lower income, had less education, or lived in rural areas had significantly lower odds of PIEB.

CONCLUSIONS

The positive relationship between PCC and PIEB further illustrates the important role of online digital communication in delivering patient-centered care and enhancing health outcomes. Since differences among subpopulations remained in PIEB, we advocate for additional structural and educational interventions to expand access to broadband and eHealth tools for these groups. This research helps inform future progress in improving quality of care and the integration of health information technology into healthcare. It also highlights the importance of continued engagement and education to provide patients with the skills and resources to actively engage in directing their medical care.

This study aims to identify the types of art archives and arrange their arrangement designs in order to support the development of the tridharma of higher education at the Indonesian Institute of the Arts (ISI) Surakarta. The archives studied are the archives of performing arts that are the result of the Tridharma organization. The research was conducted using a qualitative descriptive method. That is describing a situation based on the facts that appear. The results of field observations show that the performing arts document consists of text, audio, and video. Its creation cannot be separated from previous works of art as a reference or source of works of art. Artwork documents are archives because they are the result of the tridharma process, but have only been managed as a library. The archives are dominated by final works of art from study programs at the Faculty of Performing Arts, results of artistic research from the Research Centre, and results of community service works of art from the Centre for Community Service. ISI Surakarta Archives Retention Schedule stipulates the archive as a static archive (permanent) after the retention period expires. Its arrangement requires a design according to archival standards. The design is made by taking into account the principle of provenance and original order. The design includes archive creators, archive classification (final project reports, research, and community service), archive indexes (reports, audio visual recordings, and intellectual property certificates), archive cross-linking to link different types of archives for the same archive, information archives, access conditions and archive service procedures. Keywords: archive, arrangement, design, performing arts, tridharma

Published: November 2022

El presente estudio explora la relación entre autocompasión e imagen corporal a partir de las vivencias y los significados reportados por mujeres chilenas. Se exploró mediante una metodología cualitativa, se realizaron entrevistas semi-estructuradas a ocho mujeres normopeso entre 20 y 30 años de Chile. Los datos fueron analizados en base a la perspectiva de la teoría fundamentada. Tras el análisis descriptivo se dio cuenta de los siguientes fenómenos: (1) la apreciación corporal depende de la complexión física, la que es variable; (2) las mujeres presentan dificultad para relacionarse amablemente con su cuerpo; (3) cuando se conocen, quieren y aceptan son más autocompasivas con su cuerpo; y (4) llevar una vida saludable ayuda a tener una mayor autocompasión. A pesar de que a las mujeres les resulta fácil reconocer la insatisfacción corporal, se les hace especialmente difícil aliviarla de manera amable. Una forma de lograr aliviar más autocompasivamente es aumentando el autoconocimiento, la aceptación, el amor, la confianza y la seguridad en sí mismas; como una forma de protegerse ante las exigencias impuestas

Comparative Analysis of Geopolymer Concrete with Different Proportions of Fly ash and GGBS with Conventional Concrete Considering the Strength and Durability Parameters
Authors: Patil Vrushabh V. , Deshamukh S. P.
Published: November 2022

Abstract: The global demand of concrete for the construction of infrastructures is continuously increasing. The production of cement is highly intensive and it emits a lot of CO2 into the air which leads to the global warming. One of the effort to produce the environment friendly concrete is geopolymer concrete which emits less CO2. In the present study the feasibility of industrial by-products i.e.; Fly Ash (FA) and Ground Granulated Blast Furnace Slag (GGBS) powder as eco-friendly and sustainable is studied. So the main aim of this study is to analyse the performance of fly ash and GGBS based geopolymer concrete with conventional concrete which are compared with respect to strength and durability parameters for (7days and 28 days) curing period. In this study strength parameters includes compressive strength, split tensile strength and flexural strength and durability parameters includes acid attack test and rapid chloride permeability test. The two different proportions of (70% fly ash+ 30% ggbs) and (60% fly ash+ 40% ggbs) are used in geopolymer concrete. The Alkaline solutions used are sodium hydroxide (NaOH) and sodium silicate (Na2SiO3). The study includes casting of geopolymer concrete and conventional concrete specimens and tested for (7 and 28 days) ages for both strength and durability. The results show that Geopolymer concrete gives good strength and durability compared to conventional concrete. Thus, the Geopolymer concrete can be considered to be an environmentally pollution free construction material.
Spectral resolutions in effect algebras
Authors: Jenčová Anna , Pulmannová Sylvia
Published: November 2022

Effect algebras were introduced as an abstract algebraic model for Hilbert space effects representing quantum mechanical measurements. We study additional structures on an effect algebraEthat enable us to define spectrality and spectral resolutions for elements ofEakin to those of self-adjoint operators. These structures, called compression bases, are special families of maps onE, analogous to the set of compressions on operator algebras, order unit spaces or unital abelian groups. Elements of a compression base are in one-to-one correspondence with certain elements ofE, called projections. An effect algebra is called spectral if it has a distinguished compression base with two special properties: the projection cover property (i.e., for every elementainEthere is a smallest projection majorizinga), and the so-called b-comparability property, which is an analogue of general comparability in operator algebras or unital abelian groups. It is shown that in a spectral archimedean effect algebraE, everya∈Eadmits a unique rational spectral resolution and its properties are studied. If in additionEpossesses a separating set of states, then every elementa∈Eis determined by its spectral resolution. It is also proved that for some types of interval effect algebras (with RDP, archimedean divisible), spectrality ofEis equivalent to spectrality of its universal group and the corresponding rational spectral resolutions are the same. In particular, for convex archimedean effect algebras, spectral resolutions inEare in agreement with spectral resolutions in the corresponding order unit space.
Analyticity constraints bound the decay of the spectral form factor
Authors: Martinez-Azcona Pablo , Chenu Aurélia
Published: November 2022

Quantum chaos cannot develop faster than λ≤2π/(ℏβ) for systems in thermal equilibrium [Maldacena, Shenker & Stanford, JHEP (2016)]. This `MSS bound' on the Lyapunov exponent λ is set by the width of the strip on which the regularized out-of-time-order correlator is analytic. We show that similar constraints also bound the decay of the spectral form factor (SFF), that measures spectral correlation and is defined from the Fourier transform of the two-level correlation function. Specifically, the inflection exponentη, that we introduce to characterize the early-time decay of the SFF, is bounded as η≤π/(2ℏβ). This bound is universal and exists outside of the chaotic regime. The results are illustrated in systems with regular, chaotic, and tunable dynamics, namely the single-particle harmonic oscillator, the many-particle Calogero-Sutherland model, an ensemble from random matrix theory, and the quantum kicked top. The relation of the derived bound with other known bounds, including quantum speed limits, is discussed.

This study aims to determine the relationship between hemocyte count and hemocyte types with environmental variables and morphometric measurements in Carcinus aestuarii. A total of 240 crabs were seasonally collected in Çardak Lagoon June 2018, October 2018, February 2019, and May 2019. The average carapace length (CL) was 44.66±0.44 mm, the mean carapace width (CW) was 37.71±0.38 mm and the mean weight was 28.49±0.88 g. Crab specimens were anesthetized on ice for 10 min, and 500 µL of hemolymph was collected from the legs of each crab using a 1-mL plastic syringe. After sampling, hemolymph samples were mixed with the anticoagulant, which was applied to a Thoma slide and examined under a microscope at X40 magnification. The total hemocyte count (THC) was calculated as 13.91±8.08x106 (cells/mm3). Differential hemocyte count (DHC) 53.25±0.6% for hyalinocyte, 26.15±0.23% for semi-granulocyte, and 20.6±0.06% for granulocyte and 3 different cell types were observed. The most dominant cell type is hyalinocyte cells.

Published: November 2022

A male specimen of Achelia langi (Dohrn, 1881) was found in Antalya Bay (Turkish coast of the Mediterranean Sea) at 1.5 m depth in July 2019. A distribution map of the species in the Mediterranean Sea is provided, together with a photograph and line drawing of the species. A. langi is reported in this study for the first time from Antalya Bay and the Mediterranean coast of Türkiye and also the third time from the eastern Mediterranean Sea. The record further extends the known distribution of this species from the Aegean Sea to the Mediterranean coast of Türkiye in the eastern Mediterranean Sea.
Thermodynamic modeling of gas solubility in ionic liquids using equations of state
Authors: Cardoso Lucas , Conceição Bruno , Paredes Márcio , Mattedi Silvana
Published: November 2022

This work aimed at the thermodynamic modeling of gas solubility in ionic liquids (ILs) using the Soave-Redlich-Kwong (SRK), cubic-plus-association (CPA), and perturbed-chain statistical associating fluid theory (PC-SAFT) equations of state. Wherefore, the routines were developed for the parameterization of ILs. Then, the ILs were implemented in the Aspen plus simulator to evaluate the equations of state and explore the phase equilibrium data with the predictive equations and the correlation of the binary interaction parameter. Hence, it was verified the correlation of the density and speed of sound curves presented limitations to correcting the slope of the curves of pure ILs. Nonetheless, the PC-SAFT with the 4C associative scheme demonstrated a better fit for the thermophysical properties. As for the prediction of phase equilibrium for the [EMIM][TfO], the PC-SAFT with the 2B scheme showed a better fit with CO2, while the CPA with the 2B scheme presented the best result for H2S. For [OMIM][NTf2], the PC-SAFT with the 1A scheme showed better results with CO2, and the CPA with the 2B scheme showed the lowest deviation with H2S.

Background. Kidney disease screening recommendations include annual urine testing for albuminuria after five years duration of type 1 diabetes. We aimed to determine a simple, risk factor-based screening schedule that optimizes early detection and testing frequency.

Methods. Urinary albumin excretion measurements from 1343 participants in the Diabetes Control and Complications Trial and its long-term follow-up were used to create piecewise-exponential incidence models assuming 6-month constant hazards. Likelihood of the onset of moderately or severely elevated albuminuria (confirmed albumin excretion rate AER ≥30 or ≥300 mg/24h, respectively) and its risk factors were used to identify individualized screening schedules. Time with undetected albuminuria and number of tests were compared to annual screening.

Results. The three-year cumulative incidence of elevated albuminuria following normoalbuminuria at any time during study was 3.2%, which was strongly associated with higher glycated hemoglobin (HbA1c) and AER. Personalized screening in 2 years for those with current AER ≤10 mg/24h and HbA1c ≤8% (“Low-Risk”, 0.6% 3-year cumulative incidence), in 6 months for those with AER 21-30 mg/24h or HbA1c ≥9% (“High-Risk”, 8.9% 3-year cumulative incidence), and 1 year for all others (“Average-Risk”, 2.4% 3-year cumulative incidence) was associated with 34.9% reduction in time with undetected albuminuria and 20.4% reduction testing frequency as compared to annual screening. Stratification by categories of HbA1c or AER alone were associated with reductions of lesser magnitude.

Conclusions. A personalized alternative to annual screening in type 1 diabetes can substantially reduce both the time with undetected kidney disease and the frequency of urine testing.
Lyssnande som teologisk praktik
Authors: Rubenson Karin , Sæbø Rystad Linn
Published: November 2022

Som forskare i skärningspunkten mellan teologi och barndomsstudier delar vi upplevelsen av att när vi presenterar vår forskning i olika sammanhang mötas av vad vi tolkar som en okritisk teologisk barnsyn, som inte tar hänsyn till enskilda barns erfarenheter. I den här artikeln undersöker vi hur teologi och teologiska praktiker utmanas av att lyssna till barn som själva deltar i dessa praktiker. Vi använder oss av tidigare analyserat material från våra respektive doktorsavhandlingar (Rubenson, 2021 och Rystad, 2021). Barnen som deltar i studierna är mellan sju och tretton år och intervjuade i samband med gudstjänstfirande i Den norske kirke och Svenska kyrkan. Artikeln visar hur lyssnande som en teologisk praktik i mötet mellan barn och vuxna kan bidra till att synliggöra barns partikulära och situerade erfarenheter och därmed utmana förgivettagna sanningar.
