Published: May 2022

Background and Aims: The pivotal trial of the MiniMed™ 780G system showed that optimized settings of active insulin time (2 hours) and target glucose (100mg/dL) improved glycemic outcomes.1 This study analyzed real-world glycemic outcomes of individuals with T1D in Chile, 6 months after AHCL initiation with different settings.

Methods: Data from 37 MiniMed™ 780G system users (aged 5-76 years, mean±SD of 29.3±19.3 years) at 12 centers throughout Chile were prospectively collected and analyzed. Effects of active insulin time (AIT) and glucose target on mean GMI, TIR (70-180mg/dL) , time at <70mg/dL (TBR) and time at >180mg/dL (TAR) were determined using 14 days of sensor glucose data pre-AHCL and at 180 days post-AHCL initiation.

Results: Overall TIR increased from 74.1% to 78.4% (p<0.01) , and mean TBR and GMI were 2.7% and 6.7% at study end, respectively. Individuals (N=23) with optimized settings achieved the highest TIR (80.1%) and lowest TBR (2.6%) (Figure 1) .

Conclusion: In this real-world data analysis, MiniMed™ 780G system users who optimized their active insulin time and target glucose settings achieved the highest TIR and lowest TBR.

777-P: Short-Term Continuous Subcutaneous Insulin Infusion Treatment Improves Peripheral Autonomic Neuropathy in Type 2 Diabetes
Authors: JIN JIEWEN
Published: May 2022

Background: Short-term continuous subcutaneous insulin infusion treatment (CSII) in patients with newly diagnosed type 2 diabetes (T2DM) can improve β-cell function and insulin sensitivity, which results in long-term remission. However, the effect of CSII on peripheral neuropathy is rarely studied.

Methods: 63 T2DM patients (HbA1c>9%) were hospitalized and treated with CSII for 2 weeks. Peripheral autonomic neuropathy was measured by SUDOSCAN, which provides an age adjusted electrochemical skin conductance (ESC) composite score incorporating hands/feet ESC measurements, with a score ≤60 indicating sudomotor dysfunction. Blood glucose, HbA1c, C-peptide and SUDOSCAN were measured before and after CSII. HOMA-B was used for assessment of β-cell function.

Results: The average HbA1c of included patients was 10.5% with median duration of T2DM was 3.5 years. There were 27 (42.9%) patients who had sudomotor dysfunction at baseline. After 2 weeks of CSII, the proportion of sudomotor dysfunction (42.9% vs. 31.7%, P=0.020) was significantly deceased along with significantly improved HbA1c (10.0±1.9 vs. 8.1±1.0, P<0.001) and HOMA-B [22.0 (IQR 12.1-37.0) vs. 56.9 (IQR 42.4-81.8) , P<0.001]. Correlation analysis revealed that higher ESC composite score was correlated with better HOMA-B after CSII (r=0.445, P=0.015) .

Conclusion: Peripheral autonomic neuropathy could be improved by CSII in T2DM. The improvement of β-cell function could be responsible for the amelioration of peripheral nerve function. Keywords: Short-term continuous subcutaneous insulin infusion treatment; peripheral autonomic neuropathy; type 2 diabetes; β-cell function

830-P: The Pan-PPAR Agonist Lanifibranor Improves Nonalcoholic Steatohepatitis (NASH) and Glycemic Control
Authors: COOREMAN MICHAEL P. , FRANCQUE SVEN , DZEN LUCILE , HUOT-MARCHAND PHILIPPE , JUNIEN JEAN L. , BROQUA PIERRE , ABDELMALEK MANAL F.
Published: May 2022

Lanifibranor therapy resulted in both NASH resolution and fibrosis reduction in the phase 2b NATIVE study in patients with non-cirrhotic NASH, compared to placebo. PPAR signaling is involved in common pathways of NASH and type 2 diabetes (T2D) . We evaluated the association between the effect of lanifibranor on glycemic control (GC) and NASH markers.

Methods: NATIVE included 247 patients, randomized to lanifibranor 800, 1200 mg/d or placebo for 24 weeks of treatment; 228 patients completed the trial. Efficacy in NASH was measured with SAF score (primary endpoint) and NASH-CRN grading and fibrosis staging. Biomarkers for insulin resistance (IR) , GC, lipid metabolism, inflammation, liver enzymes and imaging of hepatic steatosis by continuous attenuation parameter (CAP) were analyzed at baseline (BL) and end of treatment (EOT) . Correlations between HbA1c (≤6, >6 - ≤7 and >7%) at BL and HbA1c change from BL to EOT with improvement in biomarkers and histologic features of NASH at EOT were assessed.

Results: T2D was present in 103 (42%) patients. The composite endpoint of NASH resolution and fibrosis improvement in the overall and T2D group for lanifibranor (pooled data) versus (vs) placebo was 26% vs. 7% (p<0.001) , and 26% vs. 3% (p=0.003) , respectively. Irrespective of T2D status, lanifibranor improved fasting glucose (FG) , IR, lipid metabolism, C-reactive protein, and liver enzymes. In contrast to placebo, lanifibranor improved mean HbA1c from BL in the overall and T2D group, -0.41% and -0.66%, respectively. In the lanifibranor group, BL HbA1c correlated with BL NASH activity and fibrosis; HbA1c decrease at EOT correlated with improvement of FG, insulin, IR, liver enzymes, HDL-cholesterol, triglycerides, ApoB, ApoB/ApoA1, CAP and histologic improvement of steatosis and ballooning.

Conclusion: GC correlates with NASH severity. The improvement of metabolic markers of NASH and hepatic steatosis with lanifibranor treatment is consistent with its beneficial effect on GC.

878-P: Maximize Benefits of SGLT2 Inhibitors in People with Advanced CKD Stages with Type 2 Diabetes
Authors: KASHIMA KOJI , SHIMIZU HIROYUKI , YAMADA MASANOBU
Published: May 2022

Objective: SGLT2 inhibitor (SGLT2i) should be considered for people with CKD with type 2 diabetes (T2D) . Since eGFR declining speed and responsiveness to SGLT2i are different in each person, we assessed renal protective effects by individual eGFR slope analysis.

Methods: A total of 75 patients with T2D with advanced CKD stage 3-4, treated by SGLT2i (empagliflozin 65% and others) were analyzed. The duration of diabetes at the time of recruitment were as follows: stage 3a (n=29) ; 11.9±5.4, stage 3b (n=28) ; 19.9±12.1, and stage 4 (n=18) ; 13.8±8.5 years. The mean of age was 70.3±12.2 year-old. GLP-1RAs was used in 41%, 64% and 44% respectively. Most rapid baseline eGFR slopes were calculated from 45.7±19.9 months before using SGLT2i, and slopes after adding SGLT2i were calculated from 39.2±11.4 months.

Results: 1) In total, the initiation of SGLT2i decreased eGFR from 46.1±14.1 to 43.6±13.5ml/min/1.73m2 (P<0.001) on the first month. 2) In total, averaged individualized eGFR slopes were improved from -6.4±9.1 to -1.5±3.2ml/min/1.73m2/year (P<0.001) . The rate of responders (responder: defined as slope are attenuated vs. baseline) in each stage were as follows: stage 3a; (22/29) , stage 3b; (22/28) , stage 4; (16/18) . Slopes in responders (60/75) were improved as follows, -7.5±9.8 to -0.8±3.0 ml/min/1.73m2/year (P<0.001) . Slopes in non-responders (15/75) were worsened as follows, -2.0±2.0 to -4.0±3.2ml/min/1.73m2/year (P<0.001) . Although no clear background differences could be found, responders were more rapid eGFR decliners and highly had macro-albuminuria (53% vs. 33%) . 3) Slopes were improved in all stages, stage 3a: -4.1±3.7 to -1.2±3.2 (P<0.001) and stage 3b; -4.9±3.7 to -1.3±3.1 (P<0.001) , and stage 4; -12.4±16.3 to -2.0±3.6ml/min/1.73m2/year (P<0.01) . In stage 4, nephrosis highly existed in 28% at the baseline.

Conclusion: To pursuit the renal benefits safely, especially starting SGLT2i in lower eGFR level in people with advanced CKD stages, individualized slope analysis is needed.

Published: May 2022

There has been a rapid rise in digital health applications to support diabetes self-management to improve patient-centered outcomes such as engagement and satisfaction. TrustSphere is a collaborative single point of access digital health application that has been developed using principles of co-creation and participatory design with health care providers (HCP) and patients/families. Our objective is to describe HCP perspectives on current challenges and ideas for digital application features. A survey was distributed to pediatric diabetes HCP across British Columbia, Canada (n=50; 36% diabetes nurse educators, 24% nursing support services, 18% pediatricians, 12% dietitians, 8% pediatric endocrinologists) . HCP identified access to mental health support (84%) , diabetes management technologies (53%) , clinical information (39%) , and support for diabetes care at school (35%) as key challenges. Qualitative data revealed struggles with staying up to date with diabetes technology and empowering patients to self-manage their diabetes between visits. HCP reported TrustSphere should include information on the type of insulin regimen (87%) , insulin doses & pump settings (76%) and patient-centered goals (41%) as well as integration of glucose meter (91%) , continuous glucose monitor (CGM) (93%) , and insulin pump data (91%) . Overall, HCP felt an integrated digital platform would greatly simplify their care for children with T1D (47%) . HCP perspectives were integrated into TrustSphere’s minimal viable product (MVP) . Via real-time connections, glucometer, CGM, and pump data have been integrated into the platform. Insulin doses, patient tasks, and management recommendations can be collaboratively entered by patients or HCP, optimizing personalized care. Educational resources and a mindfulness app to support mental health can also be accessed via TrustSphere. Next steps are a pilot study of the TrustSphere MVP with pediatric T1D patients.

way to improve the quality of mathematics learning is to apply a learning model that
s
upports the realization of real mathematics learning goals, namely by developing a
number of students' mathematical abilities including developing students' critical
thinking skills that have not been maximized when viewed from students' values
in
recent
years. Therefore, the purpose of this study is to examine the improvement of
students' critical thinking skills and student motivation in terms of parenting by
applying the
Open ended
learning model. As one alternative to overcome these
problems, mix meth
ods are conducted with explanatory sequential designs with the
aim of increasing this capability. The subjects used in the study were students of class
XI Bandung Talenta High School. In this study the instruments used were, among
others, critical thinking
ability tests, learning motivation questionnaires, parenting
questionnaires as well as observation and interview sheets. The research results
obtained are; 1) Critical thinking ability increases when applying the

A shift in customer habits in transactions can be seen: previously it was done directly and now it became online. The current pandemic situation also encourages everyone to switch to using digital banking services. To survive in the tight competition for digital banking services, BRI has developed a new mobile banking application, BRImo. This study aims to explain the influence of customer experience, online review, and perceived risk on the decision to use the BRImo application at the BRI Bali. In this study, 100 respondents were interviewed through questionnaires online with a google form. The analysis technique used is Multiple Linear Regression Analysis, Classical Assumption Test, T-Test, F Test, and Determination Coefficient Test. The results of this study indicate that customer experience has a positive effect on decision process use. The online review has a positive effect on the decision process use. Perceived risk has a negative effect on the decision process use. Customer experience, online review, and perceived risk have a significant effect on the decision process use.
Trailing Stop-Loss and Re-Entry Strategies in Europe
Authors: Duarte Elisabete
Published: May 2022

A stop-loss order is a method that can be used by investors to limit downside risk and can be explained by investors’ loss aversion. Loss aversion refers to the widely studied psychological phenomenon where expected losses have a greater impact on the investors’ preferences than expected gains. The use of stop-loss rules allows for this asymmetric profile. The stop loss hypothesis, also, states that higher returns can be obtained by limiting the downside risk of long positions. A stop-loss order can be established at a percentage of the asset value that grows over time as it rises, stopping if the asset value starts to go down (trailing stop-loss order). In this work, it is used trailing stop-loss orders (with a difference to the asset market value of 3%) with long positions in financial markets. After being stopped out in a down market, the re-entry rule is to buy the asset again as soon as the market grows by at least 3%. Whenever the portfolio is sold out by applying the trailing stop-loss rule, the investment is held in cash until the trigger is set off. In this article the rules are applied in Germany, France, Spain, and Greece during the financial crisis, to make an empirical validation of trailing stop-loss rules and re-entry rules for these markets.  It was found that the followed strategy presents mixed results, proving to beat the buy-and-hold strategy in some scenarios of rising and falling prices. But the most important result is to generate fewer losses in very volatile scenarios such as Greece in 2014.
Artificial Intelligence in Construction Projects: An Explorative Study of Professionals’ Expectations

have a huge impact on projects and project management practices in the forthcoming years. The purpose of this paper is to contribute to project management theory and practice in the construction industry by analyzing the expectations of project professionals. A mixed method based on an international survey and semi-structured interviews was applied. The results show that construction project practitioners are looking for AI solutions to support the quantitative processes mainly related to scope, schedule, cost, quality, and risk management. However, the human-related processes, such as communication and stakeholder management, are not expected to be directly enhanced by AI, although might benefit from it indirectly. The findings also demonstrate a difference between amplifying and accelerating countries, where somewhat surprisingly the latter are more ready to adopt AI in their projects.

Environmental concerns associated with synthetic plastics are detrimental and have made it very crucial to develop biodegradable polymers for commercial and industrial uses. This work investigates the biodegradability of starch (biopolymer) based bioplastics through the soil burial test (SBT) technique. The biopolymeric films were synthesized from 190 and 250 µm biopolymer particulates of manihot esculenta and triticum aestivum. Blends from each particle size were produced in varied proportions with other additives. The biopolymeric films were characterized by physical, physiochemical, thermal, and microstructural tests. The biodegradability of starch-based polymers was determined by a soil burial test for 30 days where topsoil was used as a source of microbial activity. The conventional polyethylene film was also applied to the test. The bioplastic films were observed to have cracks on the surface and became hard and brittle at the end of the testing period. The total weight loss of 46.55–63.77 % was achieved by the bioplastic films. The LDPE film showed no trace of macro-structural changes or any weight reduction throughout the soil burial test. This research concludes that bioplastic films outperformed ordinary plastic films, as they were proven to be biodegradable; and can be employed efficiently in packaging applications.

Chronic myeloproliferative disorders (CMPD) include hemoblastoses with abnormal proliferation of myeloid lineages and concomitant alterations in the peripheral blood indicators. The aim of this study was to assess the frequency and structure of ophthalmic complications as a quality of life factor in patients with CMPD. A group of patients with hemoblastoses of this type (n = 41) were surveyed using National Eye Institute Visual Function Questionnaire-25 along with a comprehensive examination by noninvasive ophthalmological techniques. The patients typically reported impaired visual acuity, visual discomfort and foreign body sensation in the eyes. Though many of the patients assessed their general health and vision as satisfactory, the vast majority (68.3%) expressed serious concerns about their visual abilities. The ophthalmological examination revealed various defects including refractive errors (61%), corkscrew dilation and tortuosity of conjunctival and retinal vessels (77.9%), recurrent subconjunctival hemorrhages (39%) and dilated optic nerve sheaths (36.6%). The survey data indicate that visual impairments significantly affect quality of life in patients with CMPD. Overall, the results underscore the importance of interdisciplinary approach in the management of patients with CMPD to enable early diagnosis and feasible correction of the ophthalmic component.

Innovación e incentivos en las nuevas narrativas de protesta: el uso de referentes audiovisuales como La casa de papel
Authors: Martínez-Riera Meritxell , Cuartielles-Saura Roger
Published: May 2022

El binomio comunicación-movilización se ha convertido en una unión indisociable en la actualidad. La acción colectiva articulada desde los entornos en línea que combina un repertorio de actuación físico y virtual requiere de referentes para movilizar a sus seguidores. Fruto de esta necesidad, los impulsores de las movilizaciones, que cada vez son más disruptivas y espasmódicas (Del Amo, 2019), encuentran en la ficción elementos para construir rápidamente imaginarios comunes compartidos que afiancen el compromiso y la identificación con la acción colectiva. A partir del análisis de una de las ficciones de mayor éxito internacional en los últimos años, la serie La casa de papel, se estudia, a través de un estudio comparativo de dos movilizaciones recientes, cómo la acción colectiva ha adoptado símbolos iconográficos y elementos narrativos de estos productos audiovisuales contemporáneos.
Psychoemotional energy potential as an indicator of human physical well-being.
Authors: Chustrak Anatoliy
Published: May 2022

It is known that positive emotions improve health and prolong a person's life, increase immunity and prevent the development of depression. The psychoemotional state worsens, concentration decreases, negative thinking prevails with a lack of energy; there is weakness, apathy, loss of self-confidence. The article presents certain theoretical and empirical results of research that reveal some positions of psychoemotional energy potential (PEEP) of a person based on psychophysiological data. In order to control and regulate the human physical well-being, the studies of changes in PEEP along with other indicators (vital capacity, heart rate, oxygen saturation, strength, weight change) of middle-aged people before and after exercise have been shown. The importance of PEEP management as an indicator of a person's physical well-being is emphasized, which in most cases is not taken into account. In order to train, work and “live at full capacity” you need not only to load yourself as much as possible, but also to be able to “zone out” and fully recover. It is revealed that psychoemotional energy potential activates a person's physical well-being. Emotional-motivational and energy-active components of different order are important features of PEEP. It is shown that taking into account the available data on changes in PEEP indicators allows regulating the general physical well-being of a person in the training process. It is established that the creation of certain conditions of human activity and training process, such as: optimization of physical activity; coping with stress and negativity through gymnastics, meditation, breathing exercises and relaxing techniques; normalization of sleep; healthy vitamin food and creativity that adds positive emotions, significantly increase PEEP physical well-being. Recommendations for PEEP stimulation are also provided.
