Polycrystalline films of CdxPb1-xS (0≤ x≤0.05) substitutional solid solutions with a cubic structure B1 (Fm3m space group) containing amorphous cadmium sulfide were obtained by chemical bath deposition. Upon reaching a critical concentration of the cadmium salt in the reactor, the films consisted of substitutional solid solution and cubic CdS with the B3 structure (F43m space group). Scanning electron microscopy established the morphological features associated with the secondary nucleation and formation of the cadmium sulfide phase. The structural characteristics of the films have been calculated by a full-profile analysis of X-ray diffraction patterns. We have revealed the correlation between phase and elemental composition of CdxPb1-xS/CdS films with their voltage and current photosensitivity. Based on the received data, we have assumed the role of the individual CdS phase for the photoconductivity mechanism of CdxPb1-xS solid solutions. Keywords: chemical bath deposition, thin films, solid solutions, cadmium sulfide, photosensitivity, current-voltage characteristics.

A comparative analysis of various methods of forming a copper (Cu) contact grid on the surface of silicon heterojunction solar cells (SHJ SC) as an alternative to the standard screen printing method using expensive silver-containing (Ag) pastes is presented. It has been shown that the use of inkjet printing for the formation of protective dielectric masks based on an organic polymer and thin buffer metal layers for the growth of a Cu contact grid by electroplating makes it possible to form a contact grid of the required shape and having sufficient adhesion to the surface of SHJ SC. Using this method, double-sided SHJ SC (size 157x157 mm2) with Cu contact mesh were fabricated, demonstrating an efficiency of 22.9% and an adhesion level of 3-5 N/mm compared to 22.6% and 1.5-2 N/mm using a similar contact mesh based on Ag paste. Keywords: solar energy, monocrystalline silicon, heterojunction solar cell, copper contact grid, electroplating, screen and inkjet printing.

Published: September 2022

Lignin is the most abundant renewable source of aromatics on earth, and conversion of it to chemicals and fuels is needed to build an economically viable renewable biofuels industry. Biological routes to converting lignin to fuels and chemicals involve depolymerizing lignin using lignin-degrading enzymes that catalyze the breaking of ether and carbon-carbon bonds in the phenolic and non-phenolic subunits of lignin. Laccases are a crucial class of lignin-degrading enzymes and are copper-containing enzymes capable of oxidizing electron-rich organic substrates such as lignin using molecular oxygen as an electron acceptor. The genome of Cerrena unicolor was recently added to the JGI MycoCosm database and has eight laccases. Two of these laccases, designated Lc1 and Lc2, predicted to have the highest likelihood for successful expression in soluble, active form were selected for characterization. Lc1 and Lc2, which share 65% sequence identity, were heterologously expressed in Komagataella pastoris (formerly Pichia pastoris), allowing characterization and comparison of their purified forms. Lc1 and Lc2 had half-lives of 16 min and 185 min at 60°C, respectively, and, based on molecular dynamics simulations, the longer half-life of Lc2 was due to an increased number and persistence of salt bridges compared to Lc1. Using model lignin-like dimers and a nanostructure-initiator mass spectrometry assay to quantify catalysis of specific bond-breaking events, both Lc1 and Lc2 had their highest activity at pH 3 and in combination with syringaldehyde as a mediator, with Lc1 having a higher catalytic efficiency of β-O-4' ether and C-C bond breaking. This comparative study demonstrates the diversity, including thermostability differences, of laccases from the same fungus, and improves our understanding of laccase catalyzed breaking of bonds commonly found in lignin, which will facilitate the developing this important class of enzymes for applications in the conversion of lignin to valuable bioproducts.
Identifying encephalopathy in patients admitted to an intensive care unit: going beyond structured information. A proof-of-concept study using natural language processing. (Preprint)
Authors: Ariño Helena , Bae Soo Kyung , Chaturvedi Jaya , Wang Tao , Roberts Angus
Published: September 2022

BACKGROUND

Encephalopathy is a severe co-morbid condition in critically ill patients that includes different clinical constellation of neurological symptoms. However, even for the most recognised form, delirium, this medical condition is rarely recorded in structured fields of electronic health records precluding large and unbiased retrospective studies

OBJECTIVE

We aimed to identify patients with encephalopathy using a machine learning-based approach over clinical notes in electronic health records.

METHODS

We used a list of ICD-9 codes and clinical concepts related to encephalopathy to define a cohort of patients from the MIMIC-III dataset. Clinical notes were annotated with MedCAT and vectorized with a bag-of-word approach or word embedding using clinical concepts normalised to standard nomenclatures as features. Machine learning algorithms (support vector machines and random forest) trained with clinical notes from patients who had a diagnosis of encephalopathy (defined by ICD-9 codes) were used to classify patients with clinical concepts related to encephalopathy in their clinical notes but without any ICD-9 relevant code. A random selection of 50 patients were used for internal validation.

RESULTS

Among 46520 different patients, 7.5% had encephalopathy related ICD-9 codes in all their admissions (group 1), 45% clinical concepts related to encephalopathy only in their clinical notes (group 2) and 38% did not have encephalopathy related concepts neither in structured nor in clinical notes (group 3). Length of stay, mortality rate or number of co-morbid conditions were higher in groups 1 and 2 compared to group 3. The best model to classify patients from group 2 as patients with encephalopathy (SVM using embeddings) had F1 of 85% and predicted 31% patients from group 2 as having encephalopathy with a probability > 90%. Internal validation found a precision ranging from 92-98% depending on the criteria considered

CONCLUSIONS

Natural language processing techniques can leverage relevant clinical information that might help to identify patients with under-recognised clinical disorders such as encephalopathy. In the MIMIC dataset, this approach can increase the cohort for study by thousands of patients with high probability.

Children and Young People’s Involvement in Designing Applied Games: Scoping Review (Preprint)
Authors: Saiger Michael John , Deterding Sebastian , Gega Lina
Published: September 2022

BACKGROUND

User involvement is widely accepted as key for designing effective applied games for health. This especially holds true for children and young people as target audiences, whose abilities, needs, and preferences can diverge substantially from those of adult designers and players. Nevertheless, there is little shared knowledge about how concretely children and young people have been involved in the design of applied games, let alone consensus guidance on how to do so effectively.

OBJECTIVE

The aim of this scoping review was to describe which user involvement methods have been used in the design of applied games with children and young people, how these methods were implemented, and in what roles children and young people were involved as well as what factors affected their involvement.

METHODS

We conducted a systematic literature search and selection across the ACM Digital Library, IEEE Xplore, Scopus, and Web of Science databases using State of the Art through Systematic Review software for screening, selection, and data extraction. We then conducted a qualitative content analysis on the extracted data using NVivo.

RESULTS

We retrieved 1085 records, of which 47 (4.33%) met the eligibility criteria. The chief involvement methods were participatory design (20/47, 43%) and co-design (16/47, 37%), spanning a wide range of 45 concrete activities with paper prototyping, group discussions, and playtesting being the most frequent. In only half of the studies (24/47, 51%), children and young people participated as true design partners. Our qualitative content analysis suggested 5 factors that affect their successful involvement: comprehension, cohesion, confidence, accessibility, and time constraints.

CONCLUSIONS

Co-design, participatory design, and similar high-level labels that are currently used in the field gloss over very uneven degrees of participation in design and a wide variety of implementations that greatly affect actual user involvement. This field would benefit from more careful consideration and documentation of the reason of user involvement. Future research should explore concrete activities and configurations that can address the common challenges of involving children and young people, such as comprehension, cohesion, confidence, and accessibility.
Effects of Commercial Exergames and Conventional Exercises on Improving Executive Functions in Children and Adolescents: Meta-Analysis of Randomized Controlled Trials (Preprint)

Published: September 2022

BACKGROUND

Exergames are promising exercise tools for improving health. To the best of our knowledge, no systematic review has compared the effects of commercial exergames and conventional exercises on improving executive functions (EFs) in children and adolescents.

OBJECTIVE

This study aimed to investigate the effects of commercial exergames and conventional exercises on improving EFs in children and adolescents.

METHODS

Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, 5 randomized controlled trial (RCT) databases (PubMed, Web of Science, Scopus, PsycINFO, and SPORTDiscus) were searched from their inception to July 7, 2022, to identify relevant RCTs. The Cochrane Collaboration tool was used to evaluate the risk of bias for each study. GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) was used to evaluate the overall quality of evidence.

RESULTS

In total, 8 RCTs including 435 children and adolescents were included in the analysis. Commercial exergames had no significant benefit on overall EFs compared to conventional exercises (Hedges g=1.464, 95% CI –0.352 to 3.280; P=.06). For core EFs, there was no evidence to suggest that commercial exergames are more beneficial for improving cognitive flexibility (g=0.906, 95% CI –0.274 to 2.086; P=.13), inhibitory control (g=1.323, 95% CI –0.398 to 3.044; P=.13), or working memory (g=2.420, 95% CI –1.199 to 6.038; P=.19) than conventional exercises. We rated the evidence for overall EFs, cognitive flexibility, inhibitory control, and working memory as being of very low quality due to inconsistency (large heterogeneity) and imprecision (low number of people). Additionally, no effects of the intervention were observed in the acute and chronic groups.

CONCLUSIONS

We do not have strong evidence to support the benefit of commercial exergaming on EFs because we did not observe a Hedges g close to 0 with tight CIs. Further research is needed to confirm this hypothesis.

Utilization of Crisis Services Following the Mass School Shooting in Uvalde, TX (Preprint)
Authors: Weitzel Kirsty , Chew Rob , Miller Adam Bryant , Oppenheimer Caroline W , Lowe Ashley , Yaros Anna
Published: September 2022

BACKGROUND

Mass shootings result in widespread psychological trauma for survivors and members of the affected community. However, less is known about the broader effects of indirect exposure (e.g., media) to mass shootings. Crisis lines offer a unique opportunity to examine real-time data on the widespread psychological effects of mass shootings.

OBJECTIVE

This study examines changes in the volume and composition of firearm-related texts to Crisis Text Line (CTL), a not-for-profit company that provides 24-7 confidential text-based mental health support and crisis intervention service, before and after the mass shooting at Robb Elementary School on May 24, 2022, in Uvalde, Texas.

METHODS

A quasi-experimental event study design was used to compare the actual firearm conversation volume post-shooting to forecasted firearm conversation volume under the counterfactual scenario that a shooting had not occurred. Conversations related to firearms were identified among all conversations using keyword searches. Additionally, proportions of issue tags (topics coded by CTL volunteer Crisis Counselors (vCCs) after the exchange) were compared in the four days before (N=249), and after (N=419), the shooting to assess changes in conversation characteristics.

RESULTS

There was a significant increase in the number of conversations mentioning firearms following the shooting, with the largest spike (compared to forecasted numbers), occurring the day after the shooting (N= 159), May 25th. By May 28th, volume reverted to within the 95% confidence interval of forecasted volume (N= 77). Within firearm conversations, “bereavement” issue tags showed a significant increase in proportion in the week following the shooting, while “isolation”, “relationships”, and “suicide” issue tags showed a decrease in proportions the week following the shooting.

CONCLUSIONS

: The results suggest that the Uvalde school shooting caused measurable increases in demand for crisis services, above what would be expected given historical trends. This work adds to a growing evidence base documenting and measuring the rippling effects of mass shootings outside of those directly impacted.

Agribusiness at the interface of a liberal economy
Authors: Martins Warley Lopes
Published: September 2022

This work presents an approach inherent to the relevance of agribusiness and its extreme importance in job creation, income generation, maintenance of the nation's food security, and the consequent contribution to the economy and national development. The study is based on bibliographic research, and analysis of documental content backed by statistical data, initially navigating through the theoretical basis of economic liberalism according to the classical tradition, with an approach to the vision of one of the main classical thinkers and theorists, Ludwig Von Mises (1881). -1973), which emerged after the propagation of Adam Smith's basic ideas of freedom. The hypothesis is that the success of Brazilian agribusiness was also possible thanks to the guidelines established by the free market economy, with a system based on the supply and demand of goods and services, without forced and coerced transactions and with minimal government involvement in the business. In this way, it is concluded that agribusiness needs to be minimally guided by freedoms, thus fulfilling its social function of supplying food to domestic and foreign trade, generating employment and income, and consequently contributing to the economy and national development, thus having to the State to interfere minimally in the respective sector, based on preserving the system of voluntary action or cooperation between the negotiation of individuals.

Published: September 2022

The research presents a study involving some challenges and conflicts inherent to the quilombola territories of the South Coast of Paraíba. In this sense, we observe, not only here, but throughout the National Territory, the emergence of inequalities, the lack of social assistance, environmental problems and the sluggishness around the processes of recognition and titling of the remaining quilombo territories. In this way, we seek to dialogue with the theoretical contributions - available on the platforms: Periódicos Capes and Google Scholar - about the territorial identity of the quilombola communities of Gurugi and Mituaçu, located in the South Coast of Paraíba - municipality of Conde - as well as the expectations aimed at the ethnic strengthening of these communities. According to the material consulted – three articles published in scientific journals-, we found that the quilombolas in question develop strategies so that their voices are heard and their rights guaranteed, above all, mobilizing for a broader and collective understanding of their quilombola identities. , since such territories have already gone through the due processes of recognition by the State, however, they still need to establish themselves ethnically as quilombola peoples.

Abstract: We generally go to supermarkets to purchase the essential needs such as groceries which are required for our day to day life we see that the billing in supermarket is done by scanning the barcode which is present on the product, due to this the billing process consumes lot of time and even the customer has to wait longer time in the line at the counter when there are some issues in scanning the barcode. So in order to solve the issues the billing system using webcam has introduced where it is implemented with some added functionality to traditional supermarket billing. This system is faster bill generation for customers. With the of webcam the system captures the images of the product and gives the information of the product such as name and price of the product and calculates the bill quickly. By this system we can reduce the time and increase the accuracy.

Aim. The aim is to study the correlation between the vaccination rate (VR) and mortality rate of patients with COVID-19 (MpCOV).

Methods. The countries with gross domestic product per capita corrected for purchasing power parity (GDP PPP) over $-10,000 were selected for an ecologic study. The city-states and countries with a population of 1,000,000 were excluded. The number of patients who died from COVID-19 within a week was divided by the number of patients diagnosed with COVID-19 within a week 20 days earlier to calculate MpCOV.

Results. We included 85 countries. VR (r = –0.604; p < 0.001) and GDPpcPPP level (p = 0.202), is an independent determinant of MpCOV. There was no significant difference in MpCOV between groups of countries with VR < 20 % and 20–39 % (1.96 [1.21; 4.67] vs. 1.96 [1.01; 3.36] %; p = 0.464). MpCOV was higher in countries where VR were lower when groups of countries with VR of 20–39 %, 40–59 %, 60–79 %, and ≥80 % were compared (1.96 [1.01; 3.36] vs. 1.11 [0.76; 1.64] vs. 0.50 [0.39; 1.00] vs. 0.16 [0.10; 0.21]; p = 0.003; p = 0.020, and p = 0.008).

Conclusions. An increase in VR correlates with a decrease in MpCOV.

Measures taken in connection with the pandemic of COVID-19 infection (introduction of lockdown, social isolation) leads to an increase in the level of depression and anxiety and, as a consequence, to an increase in the frequency and prevalence of functional dyspepsia (FD) and irritable bowel syndrome (IBS), as well as an increase in the severity of clinical symptoms of these diseases. In turn, the overcoming of COVID-19 infection contributes to an increase in the permeability of the mucous membrane of the gastrointestinal tract and the occurrence of its inflammatory changes, which lead to the development of postinfectious (postcovid) FD and postinfectious (postcovid) IBS.

Conclusion. The problem of functional gastrointestinal diseases during the pandemic of a new coronavirus infection is very important and requires further research.

Aim. To optimize the choice of treatment strategies by physicians and gastroenterologists to improve treatment and prevention of small intestinal bacterial overgrowth (SIBO) in adults.

Key points. SIBO is a condition characterized by an increased amount and/or abnormal composition of the microbiota in the small intestine. Clinically, the syndrome is manifested by nonspecific gastroenterological complaints and the development of malabsorption syndrome. Most often, SIBO is associated with various chronic non- infectious diseases (both diseases of the gastrointestinal tract, and the cardiovascular system and the neuromuscular apparatus) and can affect the severity of their symptoms. Specific methods for diagnosing SIBO are the culture method and breath tests. The main approaches to the treatment of SIBO include the elimination of the underlying cause of its occurrence, the use of antibacterial drugs and adherence to dietary recommendations (elemental diet).

Conclusion. Small intestinal bacterial overgrowth is common in patients with various diseases, but has non-specific manifestations, so proper diagnosis of this condition is required. SIBO therapy involves prescription of antibacterial agents, the most studied of which is the non-absorbable antibiotic rifaximin-α.

Introduction Oral sotalol initiation requires a multiple-day,
inpatient admission to monitor for QT prolongation during loading. A
one-day intravenous (IV) sotalol loading protocol was approved by the
FDA in March 2020, but limited data on clinical use and administration
currently exists. This study describes implementation of an IV sotalol
protocol within an integrated health system, provides initial efficacy
and safety outcomes, and examines length of stay compared to oral
sotalol initiation. Methods IV sotalol was administered according
to a pre-specified initiation protocol to adult patients with refractory
atrial or ventricular arrhythmias. Baseline characteristics, safety and
feasibility outcomes, and length of stay (LOS) were compared to patients
receiving oral sotalol over a similar time period. Results From
January 2021 to June 2022, a total of 29 patients (average age 66.0 ±
8.6 years, 27.6% women) underwent IV sotalol load and 20 patients
(average age 60.4 ± 13.9 years, 65.0% women) underwent PO sotalol load.
The load was successfully completed in 22/29 (75.9%) patients receiving
IV sotalol and 20/20 (100%) of patients receiving oral sotalol,
although 7/20 of the oral sotalol patients (35.0%) required dose
reduction. Adverse events interrupting IV sotalol infusion included
bradycardia (7 patients, 24.1%) and QT prolongation (3 patients,
10.3%). No patients receiving IV or oral sotalol developed sustained
ventricular arrhythmias prior to discharge. LOS for patients completing
IV load was 2.6 days shorter (mean 1.0 vs 3.6, p < 0.001)
compared to LOS with oral load. Conclusion Intravenous sotalol
loading has a safety profile that is similar to oral sotalol. It
significantly shortens hospital LOS, potentially leading to large cost
savings.

Published: September 2022

Background: Catheter ablation for atrial fibrillation (AF) is a
common therapeutic strategy for patients with either paroxysmal or
persistent AF, but long-term ablation success rates are imperfect.
Maintenance of sinus rhythm immediately prior to ablation with
anti-arrhythmic drug (AAD) therapy has been associated with improved
outcomes in patients undergoing ablation. Amiodarone has superior
efficacy relative to other AADs. Whether failure of amiodarone to
maintain sinus rhythm prior to ablation for either paroxysmal or
persistent AF is associated with poor outcomes is unknown.
Methods: A total of 307 patients who received amiodarone in a
one-year window before undergoing catheter ablation for AF were
included. Patients were divided into amiodarone success (n=183) and
amiodarone failure (n=124) groups based on the response to pre-ablation
amiodarone treatment. Analysis of procedural outcomes as a function of
response to amiodarone therapy was performed. Patients were followed for
at least 12 months post-ablation to assess outcomes (adverse events and
arrhythmia recurrence). Procedural success was defined by the absence of
documented arrhythmia (>30s) without any anti-arrhythmic
agents beyond a 90d blanking period. Results: Following
ablation for either paroxysmal or persistent AF, freedom from any
recurrent atrial arrhythmia at 1y was 57.7% for the entire cohort.
One-year freedom from recurrent arrhythmia in the amiodarone success
group was comparable to that in the amiodarone failure group (55.7% vs
60.5%; p=0.54). Success rates following ablation did not vary by the
response to amiodarone when analyzed for paroxysmal or persistent AF
subgroups. Conclusion: Failure to restore and maintain sinus
rhythm with amiodarone prior to ablation for either paroxysmal or
persistent AF is not a predictor of ablation procedural failure.
Amiodarone failure alone should not deter practitioners from considering
ablation therapy for patients with AF.

Superior mesenteric artery syndrome-induced pancreatitis is rarely
reported .We report a case which can be explained by an occlusive
post-papillary syndrome, which produces retrograde reflux of bile into
the pancreatic duct, activating inflammation responsible for
pancreatitis.
Renin-angiotensin System: A New Promising Therapeutic and Mechanisms for Depression and Anxiety
Authors: Gong Sizhu , deng fang
Published: September 2022

Depression was an affective disorder, and the incidence of depression
was increasing, which was projected to be the first disease burden
worldwide by 2030. Therefore, it is particularly urgent to find new
anti-depressant curative. The renin-angiotensin system (RAS) was
important for regulating blood pressure, water, and electrolyte balance.
Angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor
blockers (ARB) were commonly used as first-line antihypertensive agents.
A large number of basic studies confirmed that RAS played a key role in
hypertension, affective disorders, and neurological diseases. Recently,
studies have found that RAS blockers (ACEI/ARB) acted on the classical
ACE/AngII/AT1 receptor pathway and ACE2/Ang-(1-7)/Mas receptor pathway,
which may have promising clinical value for the treatment of anxiety
disorders and depression. Therefore, the modulation role of RAS in the
nervous system has progressively come to light. This review addresses
the overview of the RAS, the relationship between RAS and
depression/anxiety, and the potential mechanisms of RAS blockers in the
therapy of affective disorders, involving brain inflammation, HPA axis,
oxidative stress, and BDNF. The evidence for positive effects of RAS
blockers on depression and anxiety alone or comorbidity was reviewed,
hoping to provide a reference for new clinical uses, which go beyond
blood pressure management.

Hidradenitis suppurativa is a chronic disease that disrupts patients’ physical and psychological well-being. A disease-specific measure was developed and validated for assessing health-related quality of life in hidradenitis suppurativa. After qualitative item development, the quality of life in hidradenitis suppurativa instrument was tested in 101 patients, applying convergent measures and a usability questionnaire. Descriptive and validation-specific analyses were conducted. There was no ceiling, but moderate floor effects (scores between 0 and 3.13 on a scale of 0–4). Few missing values were observed (21 of 23 items < 5%). Internal consistency was satisfying: 2 subscales with 6 and 16 items were identified (Cronbach’s alpha=0.95 and 0.88). The quality of life in hidradenitis suppurativa instrument correlated significantly with all convergent criteria (including change in convergent patient-reported outcomes; p < 0.05) except for Hurley stage (p = 0.490). In conclusion, the quality of life in hidradenitis suppurativa questionnaire is an internally consistent, valid, responsive, and usable instrument to assess quality of life in patients with hidradenitis suppurativa.

Chronic urticaria is a debilitating disease that affects health-related quality of life, but few studies have evaluated its impact on psychological wellbeing. The aim of this study was to evaluate the quality of life of patients with chronic urticaria and determine its impact on their emotional and psychological wellbeing. A cross-sectional multicentre study of a cluster of 264 Lebanese patients visiting dermatology/immunology clinics was conducted between July 2018 and June 2020. The impact of chronic urticaria on quality of life was assessed using the Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL) and Dermatology Life Quality Index (DLQI), as well as its consequences on mood changes using the Patient Health Questionnaire-9 (PHQ-9) and Beirut Distress Score 22 (BDS-22) scores. A multivariable analysis of covariates was performed to determine the effect of the triggering factors of urticaria on both CU-Q2oL and PHQ-9. A moderate negative correlation was found between Urticaria Control Test and quality of life scores as well as PHQ-9 and BDS-22 (p < 0.001). Patients with the lowest Urticaria Control Test score had the highest impairment in quality of life and depression scores. In conclusion, chronic urticaria compromises patients’ quality of life and emotional wellbeing. This distress is more pronounced when the disease is more severe.
