Authors: Meletlioglu Emrah , Sadeler Recep
Published: August 2022

The aim of this in vitro study was to evaluate the influence of + Ag coated conditions on the corrosion, tribocorrosion, antibacterial properties of Ti15Mo specimens. The mean wear volume loss of all test specimens after tribocorrosion test procedures were determined to use a noncontact 3D profilometer. The specimens hardness, roughness and microstructures were measured using the micro-hardness tester, surface profilometer, scanning electron microscopy (SEM) and Xray diffraction (XRD) analysis. The mean wear volume loss of 30 min + Ag coated Ti15Mo specimen was lower than the other specimens. In this study, correlations between the hardness, surface roughness and wear volume loss were found to be significant. The PVD coating process enhanced the antibacterial activity of Ti15Mo specimens owing mainly to the formation of the silver film on substrates

Background: Optical coherence tomography (OCT) may have advantages in not only identifying etiology but also optimizing stent implantation due to its higher spatial resolution compared to intravascular ultrasound (IVUS) in contemporary percutaneous coronary intervention (PCI) for acute coronary syndrome. However, the impact of OCT-guided PCI on clinical outcomes in patients presenting with ST-segment elevation myocardial infarction (STEMI) has been scarcely reported.Methods: We retrospectively studied consecutive 533 patients presenting with STEMI who underwent either OCT-guided or IVUS-guided primary PCI (within 12 h from symptom onset) between June 2016 and December 2020. The primary endpoint was a target lesion failure (TLF), including cardiac death, target vessel myocardial infarction (re-infarction), or target lesion revascularization. Propensity score (PS) matching was performed for fair comparisons between OCT-guided and IVUS-guided PCI.Results: The patients were younger, and left ventricular ejection fraction and estimated glomerular filtration rate were significantly higher in the OCT group (166 patients, 31.1%) than in the IVUS group (367 patients, 68.9%). Killip class IV and left main disease were more common in the IVUS group than in the OCT group, while the peak level of creatine kinase was comparable between the two groups (median; 1,953 vs 1,603 U/L). Contrast volume was significantly higher in the OCT group than in the IVUS group (200 vs. 165 mL; p < 0.001). The cumulative incidence of TLF within median 2.2 years did not differ between the OCT and the IVUS groups (9.6% vs. 13.4%; p = 0.218), whereas cardiac mortality was significantly higher in the IVUS group than in the OCT group (8.7% vs. 3.6%; p = 0.040). After the PS matching (166 patients in each group), no differences in TLF and other clinical outcome measures were observed between the two groups.Conclusions: OCT-guided PCI showed comparable clinical outcomes with IVUS-guided PCI in selected patients presenting with STEMI.

Classification of Videos based on Object Detection in Video Files
Authors: Srin Suma , Baydeti Nagaraju
Published: August 2022

The primary objective of this work is to classify the videos, which comprises the extraction of video frames and generation of features vector and identification of action sequence in the video. A deep neural network has been proposed that combines Convolutional Neural Network and Long Short Term Memory models to achieve better spatial and temporal features. Video Classification is performed by extracting the features from the frames by considering the parameters viz., frame width and height, video sequence length etc. In the proposed model, the frames extracted from a video are fed into a two-layer LSTM. The outcome of the LSTM model is forwarded to the Convolution Layers with an additional Global Average Pooling (GAP) layer in place of the fully connected layer. The frames extracted from the video are sent as an input to the twolayered Convolutional 2D layer, which is followed by Batch normalization and Max Pooling. Fully connected layer is replaced by Global Average Pooling (GAP) layer followed by dense layer. Depending on the input data, more number of batch normalization and dense layers would be added in order to achieve more accuracy. UCF101 Dataset is considered to classify the videos. The results demonstrate that the LRCN methodology outperforms both the conventional CNN method and ConvLSTM in terms of prediction accuracy. The suggested approach also provides more accurate temporal and spatial stream identification. The results have shown that the probability of the action sequence is predicted to be around 82 percentage with an accuracy of 92.86 percentage.

With the accumulation of data, it is possible to study the long-term variation of Fluxgate Magnetometers (FGM) of High Precision Magnetometer (HPM) onboard the China Seismo-Electromagnetic Satellite (CSES). The calibration method of HPM depends on an assumption that the linear parameters of FGM, including the gain factors, the offsets, and nonorthogonal angles are stable. However, HPM exhibits some unexpected trends in the scalar residuals when processed according to the assumption. Study on the residual finds out that under changing space thermal conditions, the non-orthogonal angles of FGM change periodically, suggesting that the data calibration method we used before should be modified. A multi-dimensional polynomial model is established for defining the change of nonorthogonal angles of FGM as a function of the sun incidence angles, geographic latitude and sensor temperature. Apply the polynomial model to data from August 2018 to May 2021, the standard deviation of the scalar residuals is reduced to around 0.5 nT and tends to be more random and in line with the normal distribution. Meanwhile, the variation trend in gain factors and offset factors are eliminated. Results show that the model can correctly reflect the period variation of the non-orthogonal angles of FGM with the space thermal conditions.

Published: August 2022

BackgroundThe burden of disease and economic losses caused by aging populations and non-communicable chronic diseases (NCD) are significant public health concerns. Estimates of healthcare costs attributed to chronic diseases in the senior population can inform the creation of disease preventive and control policies. This study therefore utilized an econometric method to estimate the chronic disease attributable fraction (CDAF) of yearly per capita healthcare costs in older persons, which includes all potential costs.MethodsThis study employed the three waves of panel data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). The data evaluate the annual per capita utilization and cost of outpatient and inpatient healthcare for the elderly. A two-part model was utilized to estimate outpatient, inpatient, and healthcare costs associated to the six selected chronic conditions.ResultsThe top six chronic diseases of the surviving elderly in China are hypertension, arthritis, heart disease, cataract, chronic lung disease, stroke or cardiovascular disease (CVD). The CDAF for outpatient costs, inpatient costs, and healthcare costs were 44.99%, 64.73%, and 55.18%, respectively. Among them, the CDAFs of hypertension in outpatient costs and total healthcare costs were 12.53% and 12.50%; the CDAF of arthritis in outpatient costs was 5.95%; the CDAFs of heart disease in outpatient costs, hospitalization costs and healthcare costs were 17.85 %, 33.84%, and 24.49% respectively; the CDAFs of cataract in outpatient costs and healthcare costs were 4.60% and 5.67%; the CDAFs of chronic lung disease in outpatient costs, inpatient costs, and healthcare costs were 7.50%, 17.03%, and 11.96%; CDAFs of stroke or CVD in outpatient cost, inpatient cost, and healthcare cost were 7.96%, 23.54%, and 16.94%. In addition, gender, place of residence, and degree of education affect the cost attribute to chronic disease in older persons.ConclusionIn the healthcare service cost of the elderly, the attributed cost of chronic diseases has significant differences, mainly reflected in the elderly's gender, living environment, and preference for outpatient or inpatient treatment. Based on this, the prevention and treatment policies formulated for specific chronic diseases can help reduce the health and economic burden of the society.

Background: The quality of life (QoL) is progressively becoming an important issue with aging. The aim of the study was to assess the proportion and severity of menopausal symptoms and associated factors on the QoL among postmenopausal women in Mohammadpur Geneva camp. Methods: A cross-sectional study was conducted from November to March 2019. A total of 1200 postmenopausal women [present age: mean (±SD), 54.64 (±8.15) years, age at menopause: mean (±SD), 45.38 (±5.99) and duration of menopause >20 years] were selected conveniently in considering the inclusion and exclusion criteria. The modified menopause rating scale (MRS) was used to assess the menopausal symptoms. Results: The mean total score, psychological, somatic and urogenital subscale scores of the MRS were 13.96 ±6.07, 6.33 ±3.46, 6.21 ±3.02 and 1.41 ±1.76, respectively. Most of the women (90%) suffered from joint and muscle pain; the second highest prevalent symptoms were depression (78%), physical & mental exhaustion (76%), and irritability (76%). Results of c2 analysis showed that age at menopause, occupation, duration of menopause, and level of education were significantly (p≤0.05) associated with MRS subscales. OR for homemaker: 1.608 (95% CI: 1.085 to 2.382); OR for literate: 2.285 (95% CI: 1.474 to 3.543); OR for SBP: 1.015 (95% CI: 1.006 to 1.024); OR for DBP: 0.988 (95% CI: 0.976 to 1.000); and OR for duration of the menopause: 0.951 (95% CI: 0.912 to 0.991). Conclusions: The total mean MRS score indicates that the symptoms were severely severe though postmenopausal women suffer mild to moderate symptoms in the subscales score. Occupation, age at menopause, marital status, education, blood pressure and duration of menopause are significantly associated with MRS score.

Published: August 2022

The purpose of this study is to identify the exact location of cyclones to avert cyclone-related damage. Knowing about natural disasters like cyclones in advance will help with planning and preparations as they can be extremely dangerous. Numerous methods have been developed in the past to forecast cyclones and gauge their severity. It is a difficult task that demands swiftness and effectiveness. On the INSAT-3D dataset, a hybrid model of CNN and Bidi-rectional GRU is created in this study to estimate the position of the next cyclone. The INSAT-3D satellite pictures’ IR and visible images are analyzed and segmented using K-means clustering. The model’s training time is 400 ms, as observed. There have been comparisons between a variety of prior methods, including CNN-LSTM and a hybrid model that combines CNN and Bidirectional-LSTM. The suggested model’s experimental results show a training loss of 58.6879.

Published: August 2022

The purpose of this study was to evaluate the stress distribution in normal tooth structure and restoration at different preparation designs restored with stainless-steel crown (SSC), zirconia crown (Zr), and amalgam. Six carious primary mandibular second molar were used. The molars were divided into three main groups: Group I (restored with Amalgam), Group II (restored with SSC), and Group III (restored with Zr). Each group was subdivided into Subgroup A (Class II Cavity with MOD extension) and Subgroup B (pulpotomy with MO cavity extension). The restored teeth were imaged for CBCT to create a finite element model for each one. These models were transferred to ANSYS software and subjected to an average simulated masticatory force of 245 N. Regarding the tooth structure, under different force directions and cavity designs, the dentin structure of models restored with amalgam displayed von Mises stress more than models restored with SSC. The lowest von Mises stress value showed in models restored with Zr. Regarding the final restorative material under different force directions and cavity designs, the amalgam recorded the lowest value of von Mises stress than Zr and SSC. The SSC and Zr distribute occlusal stresses significantly more than amalgam restoration. Furthermore, Zr distributes occlusal stresses slightly more than SSC.

Published: August 2022

In this article we analyze the determinants and the export trend of European countries of medium and high technology products. The data were analyzed using various econometric models, namely WLS, Pooled OLS, Dynamic Panel, Panel Data with Fixed Effects, Panel Data with Random Effects. The results show that exports of medium and high-tech products are positively associated, among other variables, with the value of “Average Annual GDP Growth”, “Total Entrepreneurial Activity” and “Sales Impacts”, and negatively associated with, among other variables, “Human Resources”, “Government and Procurement of Advanced Technology Products” and “Buyer Sophistication”. A cluster analysis was realized with the k-Means algorithm optimized with the Silhouette coefficient. The result showed the presence of only two clusters. Since this result was considered poorly representative of the industrial complexity of the European Union countries, a further analysis was carried out with the Elbow method. The result showed the presence of 6 clusters with the dominance of Germany and the economies connected to the German economy. In addition, a network analysis was carried out using the distance to Manhattan. Four complex network structures and two simplified network structures were detected. A comparison was then made between 10 machine learning algorithms for predicting the value of exports of medium and high-tech products. The result shows that the best performing algorithm is the SGD. An analysis with Augmented Data-AD was implemented with a comparison between 10 machine learning algorithms for prediction and the result shows that the Linear Regression algorithm is the best predictor. The prediction with the Augmented Data-AD allows to reduce the MAE by about 0.0022131 compared to the prediction with the Original Data-OD.

Fingerprints of freeze-in dark matter in an early matter-dominated era
Authors: Banerjee Avik , Chowdhury Debtosh
Published: August 2022

We study the impact of an alternate cosmological history with an early matter-dominated epoch on the freeze-in production of dark matter. Such early matter domination is triggered by a meta-stable matter field dissipating into radiation. In general, the dissipation rate has a non-trivial temperature and scale factor dependence. Compared to the usual case of dark matter production via the freeze-in mechanism in a radiation-dominated universe, in this scenario, orders of magnitude larger coupling between the visible and the dark sector can be accommodated. Finally, as a proof of principle, we consider a specific model where the dark matter is produced by a sub-GeV dark photon having a kinetic mixing with the Standard Model photon. We point out that the parameter space of this model can be probed by the experiments in the presence of an early matter-dominated era.
Kesalahan Penerjemahan Google Translate Pada Hadis Arbain Berdasarkan Konteks Keagamaan (Kajian Akar Kata dan Morfologi Turunan)
Authors: Rahmadi Agustian
Published: August 2022

Translation is the activity producing a source language message with the closest and natural equivalent to the recipient's language, both in terms of meaning and style. The translation process requires grammatical and lexical adjustments to evade unusual structures in the recipient's language. Translation activities are not only done by humans. With the advancement of technology, electronic translation tools have emerged such as Google Translate to translate parts of text or web pages from one language to another. This study aims to describe the Google Translate system in translating a Hadith Arbain text and to analyze the forms of translation errors in the study of root words and derived morphology. This research is a qualitative descriptive study with the source of data and the object is the translation of the Google translation and the Hadith Arbain. Data collection is done by documentation. Error analysis is used in conducting data analysis of translation errors to find errors in the meaning of Arabic morphology forms against Indonesian and vice versa, grammatical errors, meaning of the same root words but different sounds, meaning of glorification, classifying words of the original language into the target language, the use of inappropriate target words, translation, and the meaning of Islamic concepts.
Coal Region as a Discursive Construct: Meanings of Coal in the Kuzbass Media Routine
Authors: Piskunova Aleksandra
Published: August 2022

In the Kemerovo Region, coal is a local socio-cultural construct that receives its substantive content through the local mass media discourse. Social studies of extractivism reveal the deep-rooted and significant impact of resource extraction on the modern society. This research relied on a discourse analysis of media routine and the meanings of coal it specifies. The method of discourse analysis is a phenomenological strategy of socio-cultural description; it clarifies the conceptual content of local media communities and registers the current state of the discursive environment. In the Kuzbass media, coal is an important resource that provides well-being, while coal mining is an extractive practice based on an unfair distribution of benefits and costs. This discourse objectifies the acts of collective signification of regional coal development activities. The economic discourse cultivates the idea of sustainable economic development of Kuzbass, while the ecological discourse defines the understanding of the specific coal-mining ecology. Media routine forms a social field of presence, where the regional community reproduces its collective identity and develops a language to describe the reality in which coal is the intersection point of economics, politics, ecology, and culture.
Effect of Regional Economic Development on Small and Medium-Sized Enterprises: Modern Concept of the Dependency
Authors: Rogova Kseniya
Published: August 2022

Small and medium enterprises (SMEs) play an important role in regional economic development. However, the results of their activities largely depend on the regional factors. The article provides an overview of the most influential and latest publications on the relationship between SMEs and regional development processes. The impact of SMEs on the growth of the regional economy proved to be assessed ambiguously. A direct positive impact is typical for high-income countries, while other countries yield mixed results. High-income countries have factors and support mechanisms that overcome the objective limitations of SMEs. In the Russian regions, SMEs perform their functions to a lower extent and, as a result, have low factor productivity, which limits their contribution to the regional economy. No unified idea of SME differentiation factors was detected in domestic and foreign publications. Abroad, a higher level of SME development is usually associated with such obvious factors as population, the size of the regional economy, availability of financing, etc. The review of domestic literature revealed some data on the differentiation of regions according to the state and SME characteristics, but no patterns that would determine these features. The review highlighted some issues for further research of the relationship between SMEs and the regional economy. The results obtained can be used to develop regional SMEs and specialized university courses.
Diagnosis del hombre actual: La propuesta de Zygmunt Bauman
Authors:   Universidad de Santiago de Chile, Chapsal Mauricio
Published: August 2022

Descripción y análisis crítico de las características principales del hombre postmoderno según Zygmunt Bauman (1925-2017). En particular, se exploran los elementos que, a la luz del pensamiento de este ensayista, sociólogo, y filósofo polaco, lo caracterizan; con ello se muestran también los supuestos filosóficos básicos a partir de los cuales lo comprende y, por ende, la necesaria relación que, en orden a lo anterior, tiene dicha noción antropológica con la realidad social. Desde esta perspectiva se analiza, además, la sociedad posmoderna entendida como una sociedad líquida, esto es, un concepto que muestra cómo la sociedad actual si bien avanza cada día hacia la globalización, las innovaciones tecnológicas, el desarrollo de nuevos modelos económicos y nuevas formas de relacionarse a nivel personal y social, en ella, no obstante, terminan debilitándose y transformándose los sólidos paradigmas y modelos tradicionales de la sociedad moderna, y en donde el hombre -a su entender- termina convirtiéndose así en víctima de sus propias decisiones, angustias, y miedos, que esta misma sociedad le presenta.
La Imbricación del factor contextual y la condición de re-identificación como motivaciones no-conceptualistas
Authors:   Universidad Alberto Hurtado, Yurisch González Joaquín Ignacio
Published: August 2022

El presente ensayo busca, principalmente, acceder de modo crítico a la interrogante de si acaso los contenidos de las experiencias perceptuales son estructurados y compuestos por conceptos de un modo análogo a actitudes proposicionales como la creencia y el deseo; para así establecer y transparentar dos argumentos –la importancia del factor contextual y la condición de re-identificación– que se constituyen, en cierta medida, como un obstáculo para la postura conceptualista. Ambos argumentos suponen una problemática a la visión que enfatiza que en todos los casos el contenido de una experiencia perceptual contiene necesariamente conceptos que especifican a cabalidad cada uno de los elementos disponibles a nivel consciente durante dicha experiencia al mismo tiempo, es decir, la visión que asevera que el contenido de las experiencias perceptuales es irremediablemente conceptual, y que estos conceptos son capaces de detallar y especificar las propiedades y los objetos dispuestos en la experiencia perceptual.

Published: August 2022

The objective was to assess the prevalence and influence of clinical and subclinical mastitis during the service period of cows in a herd in Tarumirim (MG), from October 2019 to May 2020. Around 65 Gir x Holstein and Guzerá x Holstein lactating crossbred cows were evaluated. Subclinical mastitis was diagnosed by means of the California Mastitis Test (CMT), and clinical mastitis, by means of the strip cup test and the animals’ clinical signs. Pregnancy after calving was diagnosed by the rectal palpation method, with the aid of ultrasound. The time from calving to conception was considered as the service time. The prevalence rates of clinical and subclinical mastitis were 2.9 and 63.7%, respectively, throughout the experimental period. The mean service period was shorter (p<0.05) in healthy cows (63.1 days) than in cows with subclinical mastitis (88.5 days) and clinical mastitis (111.2 days). The service period increased by 30.9 days for each mammary quarter with clinical mastitis (p<0.05). With each increase in the degree and days of duration of clinical and subclinical mastitis, the service period rose by 25.4 and 6.5 days, and 8.5 and 0.6 days, respectively (p<0.05). Therefore, mastitis increases the service period of dairy cows. Good milking hygiene and animal handling practices should be adopted in order to reduce the prevalence of mastitis in the herd.

Published: August 2022

Digoxin is a cardiotonic glycoside that is traditionally used for the treatment of heart failure and atrial fibrillation in humans and animals. However, the use of digoxin is still a challenge in clinical practice due to its narrow therapeutic range and its potential interaction with several drugs, which could facilitate the development of toxicity. A 12-year-old Labrador retriever was referred with a clinical diagnosis of heart failure and atrial fibrillation, anorexia, vomiting, and diarrhea. He had been medicated with digoxin, furosemide, lisinopril, and amiodarone. The patient also showed clinical signs of hip osteoarthritis and received firocoxib for four days. He additionally received drugs for gastrointeritis. The electrocardiogram demonstrated atrial fibrillation and signs of digitalis toxicity. Laboratory examination showed a high concentration of plasma digoxin, and 5 days after withdrawal of the drugs, the symptoms disappeared, as did the digitalis effects seen in the previous electrocardiogram.

Published: August 2022

The government's declaration of quality education equality is evidenced in the implementation of inclusive education which is in line with the philosophy of education for all. One of the learning strategies that accommodate differences in student learning needs is differentiated learning, using the Station Rotation (SR) strategy with Tiered Task (TT). The problem is that not all-inclusive schools have implemented this strategy in learning. This article aims to prove the effectiveness of implementing the SR learning strategy with TT towards improving the social skills of students with special needs (SSN) in inclusive schools. This study used an experiment, with 17 teachers participating in four inclusive schools in West Sumatra which included subject and classroom teachers, 8 observers, and 85 SSN with various types of special needs. Data were collected by observation, documentation, and questionnaires. The results showed that there was a significant effect of the SR learning strategy with TT on improving general social skills, during learning, and in the classroom environment for special needs children in inclusive schools. This increase occurs because SR and TT emphasize the flexibility of SSN in choosing study groups, evaluation of learning based on SSN abilities, and can increase positive relationships and eliminate obstacles that SSN has.

Fear has been the most common emotional response to the COVID-19 pandemic, and excessive fear is associated with various indices of psychological distress, particularly loneliness. Although most people have experienced pandemic-related fear and distress, certain groups who are on the front of service provision have experienced the pandemic in distinct ways, owing to its impact on the nature of their work. Schoolteachers represent one such group; therefore, it is imperative to identify resources that can safeguard against negative mental-health outcomes in schoolteachers. The current study investigated the potential protective role of sense of coherence (SOC) and resilience in the relationship between COVID-19 fear and loneliness. The participants were South African schoolteachers (N = 355); the participants completed the Fear of COVID-19 Scale, the University of California Loneliness Scale, the Connor-Davidson Resilience Scale-10, and the Sense of Coherence Scale-13. The results indicated that SOC and resilience had significant direct effects on loneliness, thereby suggesting their health-sustaining role. SOC and resilience also fully mediated the relationship between COVID-19 fear and loneliness. Therefore, although the provision of material resources is important, it is equally necessary to enhance people’s ability to comprehend, give meaning to, and manage the challenges associated with the pandemic. A salutogenic approach to mental health promotion in the workplace may be beneficial for enhancing SOC and resilience among schoolteachers.

Background

Men who have sex with men (MSM) are at high risk for HIV infection. Accurate estimation of the population size and monitoring the risk sexual behavioral change of MSM is of great importance to develop targeted HIV prevention and interventions.

Objective

The goal of the research was accurate estimation of the population size and monitoring the risk sexual behavioral change of MSM.

Methods

Street interception investigation methods were conducted among males aged 16 years and older in selected sites in Shenzhen in 2014 and 2019. A population survey was used to estimate the population size of MSM. Logistic regression analysis was applied to evaluate the difference in behavioral characteristics in MSM from 2014 to 2019.

Results

In this study, we surveyed 10,170 participants in 2014, of whom 448 (4.41%, 95% CI 4.01%-4.80%) participants were men who have ever had sex with another man (MSMe) and 229 (2.25%, 95% CI 1.96%-2.54%) were men who had sex with another man in the previous 6 months (MSMa). A total of 10,226 participants were surveyed in 2019, of which 500 (4.90%, 95% CI 4.47%-5.31%) and 208 (2.03%, 95% CI 1.76%-2.31%) participants were MSMe and MSMa, respectively. The results showed that the population size of MSM who are active (MSMa) in Shenzhen was 155,469 (2.29%, 95% CI 2.28%-2.30%) in 2014 and 167,337 (2.05%, 95% CI 2.04%-2.06%) in 2019. It was estimated that there were about 12,005,445 (2.04%, 95% CI 2.04%-2.04%) MSMa in China in 2019. Compared with 2014, the MSMa in 2019 were more likely to seek sex partners through mobile phone apps and less likely to have male and female sex partners in addition to having inconsistent condom use and more than 6 sex partners in the previous 6 months.

Conclusions

In Shenzhen, the proportion of MSMa among the general male population was lower in 2019 than in 2014, and the prevalence of HIV risk behavior was reduced in 2019. Although the preferred platform to find male sex partners among MSM has changed, intervention with high–HIV risk MSM could still help to reduce HIV risk behaviors among the whole MSM group. Because MSM prefer to seek sex partners through mobile phone apps, further study is needed to strengthen internet interventions with high–HIV risk MSM to curb the spread of HIV.

Background

The ongoing COVID-19 pandemic has highlighted the potential of digital health solutions to adapt the organization of care in a crisis context.

Objective

Our aim was to describe the relationship between the MyRISK score, derived from self-reported data collected by a chatbot before the preanesthetic consultation, and the occurrence of postoperative complications.

Methods

This was a single-center prospective observational study that included 401 patients. The 16 items composing the MyRISK score were selected using the Delphi method. An algorithm was used to stratify patients with low (green), intermediate (orange), and high (red) risk. The primary end point concerned postoperative complications occurring in the first 6 months after surgery (composite criterion), collected by telephone and by consulting the electronic medical database. A logistic regression analysis was carried out to identify the explanatory variables associated with the complications. A machine learning model was trained to predict the MyRISK score using a larger data set of 1823 patients classified as green or red to reclassify individuals classified as orange as either modified green or modified red. User satisfaction and usability were assessed.

Results

Of the 389 patients analyzed for the primary end point, 16 (4.1%) experienced a postoperative complication. A red score was independently associated with postoperative complications (odds ratio 5.9, 95% CI 1.5-22.3; P=.009). A modified red score was strongly correlated with postoperative complications (odds ratio 21.8, 95% CI 2.8-171.5; P=.003) and predicted postoperative complications with high sensitivity (94%) and high negative predictive value (99%) but with low specificity (49%) and very low positive predictive value (7%; area under the receiver operating characteristic curve=0.71). Patient satisfaction numeric rating scale and system usability scale median scores were 8.0 (IQR 7.0-9.0) out of 10 and 90.0 (IQR 82.5-95.0) out of 100, respectively.

Conclusions

The MyRISK digital perioperative risk score established before the preanesthetic consultation was independently associated with the occurrence of postoperative complications. Its negative predictive strength was increased using a machine learning model to reclassify patients identified as being at intermediate risk. This reliable numerical categorization could be used to objectively refer patients with low risk to teleconsultation.
A Web-Based Intervention to Improve Health Literacy and Obesogenic Behaviors Among Adolescents: Protocol of a Randomized Pilot Feasibility Study for a Parallel Randomized Controlled Trial
Authors: Fleary Sasha A
Published: August 2022

Background

Predictive theoretical models suggest that health knowledge works in conjunction with motivation and behavioral skills to influence adolescents’ obesogenic behavior. However, most of the existing adolescent interventions target these variables in isolation. Furthermore, health literacy (HL), a precursor to health knowledge, is necessary for translating health knowledge into behavior and is negatively related to adolescents’ obesity status. However, HL has not been included in obesity interventions targeting adolescents.

Objective

This study aims to pilot the feasibility of a 2-armed web-based obesity prevention intervention in school settings and assess the preliminary effectiveness of adding an HL module to an obesity prevention intervention for adolescents.

Methods

This web-based pilot feasibility study will take place in the Northeastern United States. Participants will be adolescents (aged 13-16 years) attending school, and recruitment will be conducted through flyers to parents and adolescents in participating classes or advisory groups at the school. The intervention includes 2 arms: an experimental arm that will receive an HL module and 3 obesity prevention modules and a comparison arm that will receive a vaping module and 3 obesity prevention modules. A blinded randomized procedure will be used to allocate classrooms and advisory groups to the experimental and comparison arms. The intervention will be fully web-based. Participants will complete measures of their HL and obesogenic behavior–related health knowledge, motivation, and behaviors at 3 time points (baseline, 1 month after the intervention, and 3 months after the intervention) via web-based surveys. The primary outcomes will be the measures of study feasibility (recruitment, retention, completion, and treatment fidelity rates). Secondary outcomes will be preliminary efficacy, as measured by logistic and linear regressions and calculation of effect sizes. Descriptive statistics will be calculated for all measures at each time point.

Results

This study was approved by the City University of New York Institutional Review Board in August 2020. As of June 2022, the web-based intervention design is complete and ready for use. Recruitment, data collection, and intervention implementation are scheduled to begin in September 2022. These results are expected to be published in 2023.

Conclusions

This study’s feasibility findings will inform changes to the intervention content and randomized controlled trial design. The study’s efficacy findings will inform the sample size for the full-scale randomized controlled trial and the preliminary utility of the intervention.

Development of a Mobile Application to Represent Food Intake in Inpatients: Dietary Data Systematization (Preprint)
Authors: Molter Alan
Published: August 2022

BACKGROUND

Background: Nutritional risk situations related to decreased food intake in the hospital environment hinder nutritional care and increase malnutrition in hospitalized patients and are often associated with increased morbidity and mortality.

OBJECTIVE

Objective: To develop and test the reliability of a mobile application as a virtual instrument to assess the acceptability and quality of hospital diets for inpatients.

METHODS

Methods: This intra- and interobserver development and reliability study investigated an in-hospital food intake monitoring application based on a validated instrument for patients with infectious diseases who were treated at the Evandro Chagas National Institute of Infectious Diseases (INI/FIOCRUZ). The instrument was sequentially administered to patients 48 h after admission to INI hospital units using the printed instrument (paper) and the tested digital application (ARIETI) simultaneously. The tested reliability factor was the consistency of the method in the digital platform, checking whether the application provided equivalent data to the paper instrument, and finally a statistical analysis plan was performed in the R platform version 4.2.0. This project was authorized by the FIOCRUZ/INI Research Ethics Committee under CAAE 35379820.4.0000.5262.

RESULTS

Results: The ARIETI was developed and tested for reliability in 70 participants, showing similar ability to show caloric intake in Kcal (p = 1.72 E-03), protein intake (g) (p = 0.006362), the proportion of caloric intake (p = 1.54 E-05), and the protein intake (p = 0.003501) relative to the prescribed goal. The application was superior to the paper-based instrument, accelerating the diagnosis of nutritional risk based on food intake by up to 250 s (50–350 min).

CONCLUSIONS

Conclusions: The ARIETI optimized the time between diagnosis of nutritional risk related to dietary intake and the nutritionist’s decision making, showing an improved ability to maintain information quality compared to the paper-based instrument.

BACKGROUND

Caesarean section (CS) delivery rate has increased significantly both globally and within India posing a burden on overstretched health systems.

OBJECTIVE

To analyze the trends of CS delivery from 1998-99 to 2019-21 and to understand the proximate determinants of CS deliveries in India.

METHODS

Analysis of secondary data (National Family Health Survey) of a nationally representative sample of 230,870 women (year 2019-21) was undertaken to explore the trends, distribution, and determinants of CS deliveries in India and within states. Multivariable analyses were performed to determine the proximate variables associated with CS and elective CS. The relative interaction effect of confounding factors such as number of ANC visit, place of residence and wealth status on cesarean delivery were assessed. A composite index was generated using trust, support and intimate partner violence variables named as partner human capital index (PHI) to study it’s influence on CS deliveries. State wise spatial distribution of most significantly associated factors namely wealth quintile and ANC checkups were also analyzed.

RESULTS

Overall prevalence of CS is 21.4% which had risen from 6.6% in 1998-99. The adjusted odds of CS deliveries were significantly higher among women who were highly educated (OR: 7.30; 7.02-7.60), with four-or-more ANC visit (OR: 2.28; 2.15-2.42), belonging to high wealth quintile (OR:7.87; 7.57-8.18), and from urban region. Increasing educational attainment of the head of the household (OR: 3.05; 2.94- 3.16) was also found to be a significant determinant of CS deliveries. The odds of selection in cesarean delivery based on elective and emergency were also significantly higher among richer (OR: 1.66; 1.25-2.21), and women belonging to Christian religion (OR: 1.67; 1.14-2.43). Adjusting the cesarean delivery by PHI, the odds of outcome were significantly higher among the women with moderate and high PHI compared to their counterpart women with low PHI (OR: 1.46; 1.36- 1.56 & OR: 1.61; 1.49- 1.74 respectively, p<0.001). The interaction effect of confounding factors confirms as the women with more than 4 ANC checkups, high PHI and belonging to richer wealth quintile were more likely to undergo cesarean delivery (OR: 22.22 p<0.001) compared to those with no ANC visit, low PHI, and poorest women.

CONCLUSIONS

Increasing trend of CS deliveries across India is raising concerns. Better education, wealth and good partner’s support have been incriminated as the contributory factors. There is a need to institute proper monitoring mechanisms to assess the need of CS, especially when performed electively. Also, underutilization of CS among poorer, less educated women with lower PHI raises serious concerns about access to a life-saving procedure.
