Psychometric Validation of the Korean Version of the Heart Failure–Specific Health Literacy Scale
Authors: Son Youn-Jung , Won Mi Hwa 
Published: February 2022

Background and PurposeThe goals of heart failure (HF) management include lowering adverse outcomes through optimal self-care. Health literacy has a significant role in ensuring optimal and effective HF self-care. Unfortunately, the proportion of low health literacy in HF patients is higher than those with other chronic diseases as well as the general population. Thus, healthcare providers need to screen HF patients. The HF-Specific Health Literacy Scale is a specific questionnaire to screen the health literacy in HF patients; however, the Korean version has not yet been validated. The study aimed to investigate the reliability and validity of the Korean version of the HF-Specific Health Literacy Scale.MethodsWe adopted a cross-sectional study design with 386 outpatients with chronic HF from a tertiary care hospital in Cheonan, South Korea. Data were collected from April to December 2020.ResultsThe exploratory factor analysis revealed a three-factor (functional, communicative, and critical health literacy) 12-item structure of the scale. The result of the confirmatory factor analysis confirmed a good statistical fit for the data. The Korean version of the tool demonstrated satisfactory convergent and discriminant validity. The criterion validity analysis revealed significant correlation with general health literacy and knowledge about HF. The Korean version of the tool for 12 items had adequate overall internal consistency.Implications for PracticeThe Korean version of the HF-Specific tool can be easily utilized for assessing health literacy level for HF patient education. Moreover, the tool can help healthcare providers develop strategies for promoting HF patients’ health literacy.
Youth living arrangements and household employment deprivation: Evidence from Spain
Authors: Cantó Olga , Cebrián Inmaculada , Moreno Gloria 
Published: February 2022

Objective: We study the role of employment deprivation and severe poverty at the household level on youth living arrangements in Spain in three different business cycle periods.
Background: Previous evidence has shown that recessions in Southern European countries make young individuals turn to their families for financial protection. Most analyses assume that these cohabiting decisions are only related to the young individual's employment status while other household members’ employment deprivation is irrelevant.
Method: We use information from the Quarterly Labour Force Survey between 2005 and 2017 and a very flexible indicator to measure the dimension of employment deprivation at the household level and estimate its role on the probability of being emancipated with a linear probability model. To avoid reverse causation, we also estimate two seemingly unrelated regressions of the probability of cohabiting with parents and the dimension of household employment deprivation.
Results: Our results confirm that the Great Recession increased the probability of parental co-habitation, even if with some delay in relation to the business cycle. We reject the assumption about the irrelevance of other household member’s employment deprivation on youth cohabitation decisions because its dimension determines them.
Conclusion: Policies aiming to improve emancipation should not only increase youth labour market opportunities but provide either more employment hours or more income transfers to those living in households where young individuals live.

Authors: Larasati Solichah 
Published: February 2022

Perkembangan sistem TV broadcast sudah menggunakan teknologi komunikasi satelit, salah satunya menggunakan teknologi direct to home (DTH). Standar TV digital yang digunakan dalam penelitian ini adalah DVB-S2 (Digital Video Broadcasting Satellite – Second Generation) menggunakan frekuensi Ku Band. Penelitian ini bertujuan untuk mengetahui bagaimana kualitas link transmisi DVB-S2 berdasarkan pemakaian bandwidth dan power via satelit Measat 3B. Optimalisasi bandwidth dan power dilakukan dengan menggunakan teknik modulasi QPSK, 8PSK, dan 16QAM serta nilai forwad error coding (FEC). Agar mencapai kondisi optimal pada link transmisi DVB-S2 maka dilakukan perhitungan link budget pada masing – masing teknik modulasi dengan mempertimbangkan nilai FEC dan nilai BER sesuai dengan standar ITU dan standar penyiaran DVB-S2 (ETSI 302 307). Berdasarkan hasil penelitian modulasi yang layak digunakan pada DVB-S2 adalah modulasi 8PSK dengan 8/9 dikarenakan pada modulasi ini menghasilkan nilai bandwidth dan nilai C/N yang cukup besar serta nilai Eb/No dan BER yang sesuai dengan standart yang diharapkan. Hal ini ditunjukan dengan nilai bandwidth pada modulasi 8PSK 8/9 adalah menghasilkan nilai Eb/No 13,67753 dB dengan BER 8,75844-08, sehingga kualitas sinyal yang diterima sangat baik.

Published: February 2022

AbstractPrevious works develop the method to simultaneously determine relative permeability (Kr) and capillary pressure (Pc) from corefloods – so-called steady-state-transition test (SSTT), which was designed for constant water composition. The SSTT procedure comprises simultaneous injection of water and oil with piecewise-constant increasing injected water fraction until stabilization, measuring pressure drop and effluent water cut during transition periods between the steady-states. In this work, we developed SSTT for high-salinity (HS) and low-salinity (LS) water – HS SSTT is performed in secondary imbibition mode, then the core is fully re-saturated, which follows by LS SSTT in tertiary imbibition mode. To validate SSTT, we performed continuous waterflood by HS and LS after secondary and tertiaty imbibition SSTTs, respectively. The type curves for pressure drop and average saturation are determined by numerical simulation; the raw measured data are approximated by the type curves, yielding regularization of the originally ill-posed inverse problem. The well-posed inverse algorithm produced Kr and Pc curves for HS and LS floods in Berea sandstone. Significant decrease in Kr for water and some decrease in residual oil after LS water injection is explained by mobilization of kaolinite fines by LS water, followed by fines migration and their consequent straining in thin pores: straining of fines causes the permeability decline in the carrier water and sweep improvement at the micro-scale.
Advanced Data Analysis from Laboratory Testing for Soft-Sand Completions
Authors: Gurley Kelly , Fischer Christine 
Published: February 2022

Abstract
Laboratory sand retention and dynamic fluid loss/retained permeability reservoir drill-in fluid (RDIF) testing protocols are almost always run in a linear flow configuration. While these tests may provide excellent correlations and predictive curves, the most useful form of the final data would be translated into radial flow predictions for different drawdown conditions into a wellbore. An effort has been made using data from existing sand retention and dynamic fluid loss/retained permeability RDIF testing protocols to demonstrate more complete analysis of the standard data provided from the tests, including radial flow calculations.
This paper provides an explanation of the test methods and data they generate, along with the laws and equations used to simplify the problem of linear-to-radial flow data. Constant drawdown sand retention testing provides gravel pack, screen, and clean formation permeability data, while Dynamic Fluid Loss/Retained Permeability RDIF testing on the unconsolidated formation material provides the final damaged screen permeability, remaining filtercake permeability, invaded formation permeability and the undamaged formation permeability. Using the combination of data from the two tests, translation from linear to radial flow calculations can be estimated for a wellbore scenario using the specific permeability measurements for each wellbore section, gathered from the original testing.
Using representative wellbore data, a correlation is made between laboratory permeability measurements and flow rates and expected wellbore pressures. Step by step calculations using the Radial Flow equation, assuming steady state and single phase flow, allows a simpler conversion to more typical data seen in wellbore scenarios. Calculations have been made to simplify data from constant drawdown tests and dynamic fluid loss/retained permeability RDIF testing from linear flow in laboratory conditions to estimate radial flow for wellbore conditions.
The results of this study can provide a more streamlined process to translate laboratory data from multiple tests into applicable radial flow which can be used for wellbore calculations.

Abstract
The development of effective pathogen reduction strategies is required due to the rise in antibiotic-resistant bacteria and zoonotic viral pandemics. Photodynamic inactivation (PDI) of bacteria and viruses is a potent reduction strategy that bypasses typical resistance mechanisms. Naturally occurring riboflavin has been widely used in PDI applications due to efficient light-induced reactive oxygen species (ROS) release. By rational design of its core structure to alter (photo)physical properties, we obtained derivatives capable of outperforming riboflavin’s visible light-iinduced PDI against E. coli and a SARS-CoV-2 surrogate, revealing functional group dependency for each pathogen. Bacterial PDI was influenced mainly by guanidino substitution, whereas viral PDI increased through bromination of the flavin. These observations were related to enhanced uptake and ROS-specific nucleic acid cleavage mechanisms. Trends in the derivatives’ toxicity towards human fibroblast cells were also investigated to assess viable therapeutic derivatives and help guide further design of PDI agents to combat pathogenic organisms.

Published: February 2022

Abstract

Background: Literature review using search engines is time consuming, inspiring many different systems for more efficiently integrating information including RefBin.com. This platform was used to manually extract and integrate newly reported data from 1,000 COVID-19 articles (submitted for publication). Methods: A sample of 17 students from the University of Vermont were randomly assigned to use the COVID-19 publications database or their usual preferred search methods to research eight prompts about COVID-19. The relevance and accuracy of the evidence found for each prompt was graded. A Cox Proportional Hazards Model with a sandwich estimator and Kaplan-Meier plots were used to analyze this data in a time-to-correct answer context. Results: Our findings indicate that students using the new information management system answered significantly more prompts correctly and, in less time, than students using conventional research methods. Bivariate models for several demographic factors indicated that previous research experience was the only one to confer an advantage in study performance, though it was found to be independent from assigned research method. Conclusions: The results from this pilot randomized trial present a potential tool for more quickly and thoroughly navigating the literature on expansive topics such as COVID-19.
Effects Of Intensive Insulin Therapy On The Retinal Microvasculature In Patients With Type 2 Diabetes Mellitus: A Prospective Observational Study
Authors: Yang Ning , Li Ming-Xin , Peng Xiao-Yan 
Published: February 2022

Abstract
Background: We examined the changes in retinal microvasculature in type 2 diabetes mellitus (T2DM) using optical coherence tomography angiography (OCTA) before and after intensive insulin therapy.Methods: This prospective observational study recruited patients with T2DM and divided them into intensive insulin therapy and oral hypoglycaemic agent groups according to different hypoglycaemic methods. All patients enrolled in this study had diabetes without retinopathy or non-proliferative diabetic retinopathy. OCTA was used in all patients before treatment and at 1, 3, and 6 months after treatment. Changes of vessel density and thickness in the macular and optic disc areas were assessed. Results: The study included 36 eyes in the intensive insulin therapy group and 36 eyes in the oral hypoglycaemic agent group. During the 6-month follow-up, the funduscopy findings of all patients were stable, without significant progression of retinopathy. One month after treatment, vessel density in the deep capillary plexus (DCP) and peripapillary capillary vessel density (ppVD) were significantly decreased by intensification (P=0.009, 0.000). And, ppVD was significantly lower in the intensification group than in the oral agent group(P=0.000). At 3 months after treatment, decreases in vessel density induced by intensification were found in the superficial capillary plexus (SCP), DCP, foveal density in a 300-μm-wide region around the foveal avascular area (FD-300), and ppVD (P=0.032, 0.000, 0.039, 0.000). The vessel densities of SCP, DCP, FD-300, and ppVD were significantly lower in the intensification group than that in the oral agent group (P=0.002, 0.004, 0.039, 0.001). Six months after treatment, decreases in vessel density by intensification were observed in the DCP and ppVD groups (P = 0.000, 0.000). The Vessel densities of DCP and ppVD in the intensification group were significantly lower than those in the oral agent group (P = 0.004, 0.004). In the oral hypoglycaemic agent group, vessel density showed no significant change after treatment.Conclusions: Insulin-intensive treatment caused a transient reduction in vessel density in both the macular and optic disc areas. Retinal microvasculature monitoring using OCTA is important for patients with type 2 diabetes receiving intensive insulin therapy.

Abstract
It is important to monitor labor progress and identify the possibility of vaginal birth. Based on intrapartum sonographic findings, we describe the prediction models for evaluating fetal occiput rotation and vaginal delivery. We performed serial intrapartum ultrasonography in nulliparous women with singleton cephalic presentation at term in the latent phase and every three hours after that. Six hundred and fourteen women were included in our study, of whom 524 underwent vaginal delivery, and 90 required cesarean section. The percentage of women with fetuses in non-occiput anterior(non-OA) position at the latent phase was 53.9% (331 cases), as 257(77.6%) women underwent spontaneous rotation to OA position before delivery, 74 (22.4%) women were with persistent occiput posterior (OP) position or occiput transverse (OT) position. We developed a model based on the maternal height and middle angle to predict the spontaneous fetal occiput rotation, with the C statistic was 0.667 (95%CI 0.583-0.751). Moreover, a prediction model based on the maternal height and angle of progression to evaluate whether women underwent vaginal delivery was also developed, of which the C statistic was 0.738(95% CI: 0.763-0.793). Both models showed satisfactory calibration. Our approach provides helpful information for predicting vaginal delivery and internal fetal occiput rotation.

Abstract
Objectiveto quantify macular vessel densities (VD) in patients with birdshot chorioretinopathy (BSCR) and investigate the correlation of these parameters with other features of the disease.DesignSingle-center cross-sectional studyMethodPatients with BSCR and healthy controls underwent projection-resolved OCT-angiography (PR-OCTA, RTVue XR Avanti, Optovue). The foveal avascular zone (FAZ) area, the macular VD in the superficial capillary plexus (SCP) and deep capillary plexus (DCP) were recorded. Univariate and multivariate analyses were performed to evaluate the association between PR-OCTA parameters and other clinical and imaging findings.Resultsseventy-five patients (138 eyes) with BSCR and 27 healthy age and sex-matched controls (27 eyes) were included in the study. The VD in both SCP and DCP were significantly lower in the BSCR group compared to the control group (p< 0.001). The FAZ area was similar between both groups. Multivariate analysis showed visual acuity and visual field mean defects to be associated with VD in the SCP, while central macular thickness and the visual field were associated with VD in the DCP. Eyes with a disrupted macular ellipsoid zone had a lower VD in the SCP and DCP (p<0.001).ConclusionsQuantitative evaluation of the macular vessel density might be a new promising tool for monitoring BSCR severity.
