Mechatronic Design of A Composite Vibration Isolation System
Authors: Ghoneam Sobhy , Hamada Ahmed , Elkholy Ahmed M.
Published: April 2023

Composite materials have attracted researchers in vibration and noise control applications due to their significant dynamic characteristics such as high strength and high damping level. In this paper, a Glass Fiber Reinforced Composite material (GFRC) is presented as a vibration isolation system to control vibration levels in industry. A prototype of an industrial cam–follower machine is motorized, and the Frequency Response Function (FRF) is recorded using a B&K data acquisition analyzer at five rotational speeds. The transmitted vibrations to the machine foundation are estimated without any isolation system. Then, two optimized GFRC plates of optimum stacking sequences are used as an isolation system to reduce the transmitted vibration. The displacement transmissibility is calculated theoretically and experimentally. Furthermore, the isolation system is integrated with a mechatronic system for improving the isolation performance and enhancing the machining process. The results show that the use of GFRC plates as an isolator reduces the vibration level of the system by 98.46% and 98.5% for [90/90/90/0/0]s and [90/±45/±35/90/±35]s GFRC configurations respectively. Finally, this study proposes a novel strategy for isolation and vibration control technique by employing GFRC plates. The proposed mechatronics control system can be utilized for enhancing system performance and increasing the control of vibration levels.

Published: April 2023

Teenage pregnancy refers to pregnancy that occurs in adolescent females under the age of 18 years old, although some authors include females under the age of 20 years old. Teenage girls have a higher risk of developing complications related to pregnancy, and the rate of caesarean section can rise dramatically. Cases of teenage women with pregnancy must be approached in a multidisciplinary manner and need a closer check-out than other pregnancies.
The following study was conducted in the Clinical County Hospital, Saint Andrew the Apostle’ Constanta, over a period of five years, between 2018-2022, and followed the incidence, socio-cultural environment, rate of caesarean section and indications for surgery.
Venetoclax plus Azacitidine as the Induction Therapy for Cardiac Myeloid Sarcoma - A Case Report with Review of Literature
Authors: Lin Li-Chun , Wu Cho-Kai , Lu Cheng-Hsun , Shun Chia-Tung , Huang Tai-Chung
Published: April 2023

BackgroundCardiac myeloid sarcoma is a rare extramedullary tumor of acute myeloid leukemia, and its optimal treatment strategy has not been established such as avoiding conventional anthracycline-containing induction chemotherapy because of unwanted cardiotoxicity. Recently, venetoclax combined with azacitidine was approved for newly diagnosed acute myeloid leukemia patients who are not unsuitable for intensive chemotherapy. To the best of our knowledge, there have been no reported cases of cardiac myeloid sarcoma treated with this combination regimen.Case presentationA 63-year-old man presented with progressive dyspnea on exertion. Echocardiography showed a massive pericardial effusion. Computed tomography of the chest revealed an infiltrative mass at the right atrioventricular groove with thickened epicardium and pericardium, and multifocal lymphadenopathy. Initially, he was suspected to have IgG4-related disease and Erdheim-Chester disease, based on elevated serum lgG4 levels and histopathological findings of axillary lymph node and endomyocardial biopsy. Despite treatment, his left ventricular systolic dysfunction rapidly deteriorated. Peripheral blood blasts were unexpectedly observed later, and subsequent bone marrow examination confirmed acute myeloid leukemia. Retrospective review of the endomyocardial biopsy specimen verified the diagnosis of cardiac myeloid sarcoma. To minimize the risk of chemotherapy-induced cardiotoxicity, we chose venetoclax plus azacitidine as induction therapy, followed by high-dose cytarabine consolidation and allogeneic hematopoietic stem cell transplant, which lead to a complete remission.ConclusionsAlthough extremely rare, cardiac myeloid sarcoma can cause fulminant heart failure and should be included in the differential diagnosis of cardiac tumors, even without a prior history of hematologic disorders. Our report demonstrates for the first time that the combination of venetoclax and azacitidine is an effective and safe induction therapy for cardiac myeloid sarcoma.

Published: April 2023

Drought stress has become the most widespread environmental factor that affects cocoa production in West Africa. This study assessed the effect of AMF and or potassium fertilizer on cocoa drought resilience and survival at the nursery stage to 2 years after transplanting to field. Nursery and field experiments were conducted at the FRNR Farm (6043 N and 1036 W), KNUST- Ghana from 2020 to 2022. A 3x3x2 factorial experiment with three cocoa varieties (V1, V2 and V3), three levels (0, 2 and 4g plant− 1) of potash and AMF spore treatment (AMF and Non-AMF) in a Randomized Complete Block Design was used. Soil samples (0-20cm depth) from cocoa rhizosphere in five farms were examined for native AMF spores and structures using the Wet Sieving and Decantation methodology and the Sucrose Centrifugation Technique. AMF inoculum was prepared using the trap culture technique. At the nursery, K levels with AMF recorded the highest stem diameter (8.3mm) than the non-AMF seedlings (7.9mm). 2g and 0g K with AMF in V2 and V3 had the highest (p < 0.05) plant heigh (50.27cm). 2g K x AMF in V1 and V2 had the highest aboveground (5.13g) and belowground (2.81g) biomass respectively. At 24 months, V1x0g and V3x4g both without AMF had mortality of 60% and 50% respectively, while V1x4g and V2x2g both with AMF had 2% mortality rate. This synergy improved the field survival of cocoa from the current 30–98%. This has implications for cocoa nutrients management and drought conditions that threaten sustainable cocoa production.
Quantum atmosphere effective radii for different spin fields from quantum gravity inspired black holes
Authors: Gingrich Douglas M.
Published: April 2023

Quantum atmosphere effective radii for the emission of spin-0, 1/2, 1, and 2 massless fields from Schwarzschild, Tangherlini, non-commutative geometry inspired, and polymeric black holes are calculated. The power observed from the black hole at spatial infinity taking greybody factors into account is compared to an equal-power black-body radiator of the same temperature but different effective radius. A large range of different radii are obtained for different spin fields and black holes. The equal-power black-body effective radius is not, in general, a good proxy for the location of the quantum atmosphere.

Published: April 2023

Considering the significant importance of investigating of pull-in instability and determining the pull-in voltage in nano-sensors and nano-actuators, in this article, the determination of the pull-in voltage of these structures is discussed based on the machine learning method. MLP neural network and SVR methods, which have good ability to estimate data and regression, are considered for this purpose. In this regard, the number of 500 data have been considered for training of these approaches. For the training process, the pull-in voltage has been set as the target and the physical and geometric characteristics of nanostructures are considered as inputs. The exact value of pull-in voltage for training has been determined using the SSLM together with Galerkin methods; where is a reliable procedure to determine of pull-in voltage. The type of employed MLP is feed forward back propagation and its utilized learning process is the Levenberg Marquardt. The number of layers and neurons for each layer have been checked by practicing different configurations, the most optimal mode includes two hidden layers and the number of 10 and 8 neurons in the first and second hidden layers. Also, SVR with RBF kernel has been also used. By comparing the performance of two methods, it was found that MLP has a relatively good ability to estimate the pull-in voltage. Also, the capability of neural networks in determining the pull-in voltage has been examined according to the results presented in the previous reference, and the characteristics of these structures were not considered in the training process of the machine learning method. The obtained results show the very good capability of the neural network in determining the pull-in voltage of nanostructures in previous study as well.
Trends in outcomes used to measure the effectiveness of UK-based support interventions and services targeted at adults with experience of domestic and sexual violence and abuse: A scoping review.
Authors: Carlisle Sophie , Bunce Annie , Prina Matthew , Cook Elizabeth , Barbosa Estela , McManus Sally , Feder Gene , Lewis Natalia
Published: April 2023

Objectives: In the UK, a range of support services and interventions are available to people who have experienced or perpetrated domestic and sexual violence and abuse (DSVA). However, it is currently not clear which outcomes and outcome measures are used to assess their effectiveness. The objective of this review is to summarise, map and identify trends in outcome measures in evaluations and reports of DSVA services and interventions in the UK.
Design: Scoping review
Data sources: MEDLINE, EMBASE, PsycINFO, Social Policy and Practice, ASSIA, IBSS, Sociological abstracts and SSCI electronic databases were searched from inception until 21st June 2022. Grey literature sources were identified and searched.
Eligibility: We included randomised controlled trials, non-randomised comparative studies, pre-post studies and service evaluations, with at least one outcome relating to the effectiveness of the support intervention or service for people who have experienced and/or perpetrated DSVA. Outcomes had to be assessed at baseline and at least one more time-point, or compared to a comparison group.
Charting methods: Outcome measures were extracted, iteratively thematically grouped into categories, domains and subdomains, and trends were explored.
Results: 80 studies reporting 87 interventions or services were included. A total of 426 outcome measures were extracted, of which 200 were used more than once. The most commonly reported subdomain was DSVA perpetration, and cessation of abuse according to the Severity of Abuse Grid was the most common individual outcome. Analysis of temporal trends showed that the number of studies and outcomes used has increased since the 1990s.
Conclusions: Our findings highlight inconsistencies between studies in outcome measurement. The increase in the number of studies and variety of measures suggests that as evaluation of these services and interventions matures, there is an increased need for a core of common, reliable metrics to aid comparability.

Origin of breath isoprene in humans is revealed via multi-omic investigations
Authors: Sukul Pritam , Richter Anna , Junghanss Christian , Schubert Jochen K , Miekisch Wolfram
Published: April 2023

Isoprene is amongst the most abundant volatile metabolites produced by plants and animals. Human exhaled isoprene is related to various pathophysiology but the origin was yet uncertain. Among 2000 individuals screened within consecutive mass-spectrometric studies, five healthy adults without breath isoprene were identified. Whole exome sequencing in these individuals revealed a shared homozygous (< 1% prevalent) IDI2 stop-gain mutation preventing conversion of isopentenyl diphosphate to dimethylallyl diphosphate (DMAPP) in cholesterol metabolism. Targeted sequencing depicted that the IDI2 variant is heterozygous in isoprene deficient blood-relatives and absent in unrelated isoprene normal adults. Wildtype IDI1 and cholesterol metabolism related serological parameters were normal in everyone. IDI2 determines isoprene production as DMAPP is the only source of isoprene and unlike plants, humans lack isoprene synthase and its homologue. Human IDI2 is only expressed in skeletal-myocyte peroxisomes and instant spikes in isoprene exhalation during muscle activity confirm the origin from muscular lipolytic cholesterol metabolism. Well-defined endogenous origin translated isoprene as a clinically interpretable breath biomarker.
Cost Analysis of Using Cover Crops in Citrus Production
Authors: Chakravarty Shourish , Wade Tara
Published: April 2023

Florida has a long association with citrus (Citrus sp.) production. However, the citrus industry in Florida has been devastated by Huanglongbing (HLB) or citrus greening disease (Candidatus Liberibacter asiaticus). HLB affects the citrus tree phloem and eventually causes tree death. Cover crops, or noncash crops, have traditionally been used in row crop production to improve soil organic matter, for nitrogen fixing, and for weed control. Citrus growers may benefit from adopting cover crops because healthier soils could improve yields and fruit quality of citrus trees. However, growers are uncertain about the costs and benefits associated with cover crop investments. The objective of our study was to analyze whether cover crops represent an economically feasible option for Florida citrus growers. We calculated the break-even prices for ‘Valencia’ and non-‘Valencia’ oranges (Citrus sinensis) in terms of price per box (equivalent to 90 lb of oranges in Florida) and price per pound solids per box (amount of soluble solids per box of oranges) by considering additional costs and short-term savings from using cover crops across various yield and quality scenarios based on the past 10 years of data. Considering the short-term savings from adopting cover crops, the per-acre cost of production increased by $107.3/acre or by 5.73% and constituted 5.42% of the total production cost during the first year of adoption. After the 2018–19 peak, the yield and quality for both ‘Valencia’ and non-‘Valencia’ oranges have decreased steadily. Adopting cover crops in the current yield–quality scenario will not be profitable for either ‘Valencia’ or non-‘Valencia’ oranges. However, for ‘Valencia’ oranges, at the median yield and quality levels of 193.5 boxes/acre and 6.08 lb solids/box, respectively, cover crop adoption would be profitable because the break-even price of $2.25/lb solids would be comparable to the market prices of the past 5 years.
Narain CFTs from qudit stabilizer codes
Authors: Kawabata Kohki , Nishioka Tatsuma , Okuda Takuya
Published: April 2023

We construct a discrete subset of Narain CFTs from quantum stabilizer codes with qudit (including qubit) systems whose dimension is a prime number. Our construction exploits three important relations. The first relation is between qudit stabilizer codes and classical codes. The second is between classical codes and Lorentzian lattices. The third is between Lorentzian lattices and Narain CFTs. In particular, we study qudit Calderbank-Shor-Steane (CSS) codes as a special class of qudit stabilizer codes and the ensembles of the Narain code CFTs constructed from CSS codes. We obtain exact results for the averaged partition functions over the ensembles and discuss their implications for holographic duality.

DETERMINATION OF RESIDUAL METHANOL AND ETHANOL IN BIODIESEL BY 1H-NMR
Authors: Santos Samuel , Dutra Cassiane , Fontoura Luiz
Published: April 2023

Alcohol residues in biodiesel can be present even after the purification steps. It diminishes the flash point, lubricity and cetane number. The standard technique to quantify residual alcohol in biodiesel is the FID-GC with headspace sampling. NMR, although underused for quantitative analyses, requires no special sample preparation, and consumes low volume of solvent. In this work, methodologies for the residual methanol and ethanol contents in soy biodiesel by 1H-NMR in a 9.4 T (400 MHz) spectrometer by standard addition were developed and validated. Quantification limits were found equal to 0.07 and 0.08% respectively, so more than twice lower than the maximum level acceptable, which is 0.2%. Accuracy and precision were considered suitable for the alcohol content around the specification limit.
Seguimiento de anfibios en Navarra mediante censos poblacionales
Authors: Gosá Alberto
Published: April 2023

Hace poco más de dos decenios comenzaron los primeros seguimientos de poblaciones de anfibios en Navarra. La primera especie monitoreada mediante censos en sus cinco subpoblaciones desconectadas que mantiene en la provincia fue Rana dalmatina Bonaparte, 1840. Los resultados de este periodo no han detectado un decrecimiento poblacional, a lo que ha debido contribuir el programa de recuperación del hábitat reproductor emprendido y el mantenimiento de las manchas forestales (robledal) remanentes donde desarrolla su ciclo biológico en fase terrestre. Posteriormente se iniciaron los seguimientos de comunidades completas de anfibios en espacios protegidos, como el Parque Natural de las Sierras de Urbasa y Andía y las Zonas Especiales de Conservación de la Sierra de Aralar y Roncesvalles-Selva de Irati, donde, en el mejor de los casos, se cuenta con seguimientos discontinuos de 14 años. Más recientemente, se ha iniciado el censo de poblaciones en una zona no protegida y alterada de la Navarra Media, en los valles de Aranguren y Egüés, donde se llevan realizados cuatro años de seguimiento. Los resultados, todavía preliminares, no muestran en general procesos de declive poblacional.

Authors: Kyritsakas Grigorios , Boxall Joseph B. , Speight Vanessa L.
Published: April 2023

Water utilities collect vast amounts of data, but they are stored and utilised in silos. Machine learning (ML) techniques offer the potential to gain deeper insight from such data. We set out a Big Data framework that for the first time enables a structured approach to systematically progress through data storage, integration, analysis, and visualisation, with applications shown for drinking water quality. A novel process for the selection of the appropriate ML method, driven by the insight required and the available data, is presented. Case studies for a water utility supplying 5.5 million people validate the framework and provide examples of its use to derive actionable information from data to help ensure the delivery of safe drinking water.
Influence of vegetation change on water consumption in watersheds
Authors: Fawen Li , Xinya Jiao
Published: April 2023

Evapotranspiration is one of the hot issues of ecological hydrology. However, few studies have analysed the impact of vegetation changes on water consumption from the perspective of natural and artificial vegetation. Taking the Ziya River Basin as an example, the daily meteorological data from 2001 to 2015 were used to calculate the water consumption of vegetation based on the Penman–Monteith model. The results showed that the vegetation coverage increased. The total water consumption increased from 2001 (2.60 × 1,010 m3) to 2005 (2.65 × 1,010 m3) and decreased from 2005 (2.65 × 1,010 m3) to 2015 (2.40 × 1,010 m3). The water consumption per unit area in descending order was mixed forests (660 mm, annual average), croplands (640 mm), closed shrublands (581 mm), deciduous broadleaf forests (528 mm), grasslands (514 mm), savannas (459 mm), and woody savannas (454 mm). Finally, the regression equation between vegetation coverage change and water consumption was y = 0.377x + 84.516, which showed that there was a proportional relationship. Therefore, attention should be given to balancing local water allocation during vegetation restoration. The results can provide a reference for vegetation restoration policies
Reescribir la historia constitucional desde abajo: el aporte de las peticiones populares a la Asamblea Constituyente Argentina de 1949
Authors: Leticia Vita
Published: April 2023

A história constitucional mais tradicional favorece vozes de especialistas e a visão estatista do direito. Suas fontes favoritas são, logicamente, as oficiais. A maior parte da história constitucional argentina não se desvia dessa descrição. Centra-se no século XIX, prioriza fontes secundárias, legitima o poder sem questioná-lo e reproduz uma abstração que oculta a exclusão anterior de grupos como mulheres, trabalhadores, indígenas, entre outros. Inspirado na perspectiva da história crítica do direito e da história “de baixo para cima”, este texto tem como objetivo destacar a importância de revisitar a história constitucional recuperando vozes não qualificadas do direito como a das classes populares. Para ilustrar isso, apresenta o caso da experiência constitucional argentina de 1949. Nesse contexto, centenas de coletivos apresentaram petições à assembleia constituinte, expressando suas propostas de reforma constitucional de forma bastante espontânea. O que essas manifestações mostram são os significados e expectativas que essas pessoas comuns tinham sobre o direito constitucional que entendemos, elas também fazem parte dessa história constitucional e a enriquecem.
A Study for examining the method of commentary on 『Shijing(The Classics of Poetry)』 through ｢Dúshīsuíbǐ(讀詩隨筆)｣ by a scholarin the late Joseon Dynasty, Lee Sang-soo
Authors:   The Association of DaeDong-Hanmun, Shin Jae-Sik
Published: April 2023

The purpose of this paper is to examine the method of commentary on 『Shijing(The Classics of Poetry)』 through ｢Dúshīsuíbǐ｣ by a scholar in the late Joseon Dynasty, Lee Sang-soo(1820~1882).
He was a Horon scholar and a nongam literaturer in the late Joseon Dynasty. He was associated with various litterateurs and scholars of the Horon and Nongam worlds, and combined the strengths of Philology and rhetoric. This provides an opportunity to use various commentary methods in the study of Chinese classics. A typical example is ｢Dúshīsuíbǐ｣. It is a commentary on 『Shijing』, and a collection of short essays that describe opinions, impressions, and opinions in a free form. It is in the form of aimed at poems about the ruling party's mismanagement, analyzed the background of the incident and the feelings of the characters, and advanced one's own opinion. This is a case that reveals not only the insight of a scholar of scripture but also the aspect of a writer.
As a result of examining the method of its commentary on 『Shijing』, It was found that the pattern consisted of two main parts. First, Reinforcement of reasoning through narrative. Second, Reinforcement of reasoning through lyricism. First, It is to secure the trust of the readers, and reflects his bibliographical opinion, which judged that historical records close to the time of the writing of 『Shijing』should be used as a basis. It was intended to elicit sympathy from readers, and his rhetorical view was reflected in his understanding of the literary quality of 『Shijing』as ‘inducing empathy through empathy’. Therefore, his way of interpreting the scriptures can be said to be a case of succession and transformation of the merits of Philology and rhetoric.
A Study of the Compilation of Selected Poems, Cheonggusicho and Its Meaningin Korean Chinese Literature History
Authors:   The Association of DaeDong-Hanmun, Koo Jea-hyoun , Choi Jae-won
Published: April 2023

The main purpose of the present study is to elucidate the background and process in the compilation of selected poems, Cheonggusicho published by the Japanese Government-General of Joseon and its meaning in Korean Chinese literature history. Because Kim, Taejun made a diachronic study of Korean Chinese literature history to describe ancient parts of Joseon Chinese Literature History by using a lot of Cheonggusicho.
The Competitive Exhibition of Local Products for the Fifth Anniversary of New Politics’ held by the Japanese Government-General of Joseon provided an occasion to publish Cheonggusicho. It was held to commemorate the fifth year of Japanese rule of Joseon and to make Joseon merged as a colony of Japan.
Though Cheonggusicho was published to commemorate the fifth year of Japanese rule of Joseon, it was not a local product. It seems that its aim was for some Japanese to enjoy Korean folk culture, due to the words in the preface, “to give the books printed by the typographic culture of Joseon to the ‘persons interested in the same subject’”. It is doubtful why Cheonggusicho was taken to Joseon Chinese Literature History.
Cheonggusicho consists of 176 poems stemmed from Gojoseon, the first Korean kingdom, to the Goryeo dynasty. Over 130 poems in it were recorded on Dongmunseon. The poems representing each historical era are arranged in chronological order with a poem a poet. It is different from other anthologies. So the origin of Joseon poetry dates back to the earlier era.
According to the preface of Joseon Chinese Literature History, it does not belong to Chinese Literature because it is the translated Chinese character version of native Korean words. At that time when Kim, Taejun wrote Joseon Chinese Literature History, Samgukyusa(Memorabilia of the Three Kingdoms) began to spread and the literary approach to Hyangga(old Korean folk songs), Korean myths and folktales emerged in the academy. That Chinese Literature in Korea should belong to Joseon Chinese Literature History was under discussion.
In conclusion, though Cheonggusicho was published for some Japanese to enjoy Korean folk culture, it is a clue to spread the origin of old Korean literature by Kim, Taejun at that time when the concept of literature began to change.

Authors: Fajar Muhammad Kharis , Rusdiawan Afif , Ar Rasyid Muhammad Labib Siena
Published: April 2023

This study aimed to determine the effect of giving three different exercise methods (Plyometric, SAQ, and Traning Circuit) on increasing leg muscle power and dolyo chagi kick speed in taekwondo athletes. The research design used pre and post design with a total of 18 Unesa student taekwondo athletes as research subjects. The subjects were divided into three groups (PLY, SAQ, and ST) consisting of 6 athletes each. The PLY group performs plyometric; The SAQ group performs Speed, Agility, and Quickness; and the ST Group performs circuit training. Interventions were given to each group with 18 meetings with a frequency of 3 times each week. Data analysis using manova test assisted with R studio software. The results of this study showed that the average value of the increase in leg power and kick speed was the highest in the SAQ group respectively 2.95±2.40 watts and 1.30±0.80 m/s. The manova test showed a p value of 0.1239 which means that there is no significant difference from the three training methods to leg power and kick speed. In conclusion, plyomeric training methods, SAQ, and training circuits can increase dolyo chagi leg power and kick speed in taekwondo athletes, but there is no significant difference in the improvement.
The prevalence of depression and generalized anxiety disorder among pregnant women in primary healthcare centers of Al Madinah Al Munawara City 2020-2021
Authors: Bagadood Wejdan Hassan , Bagadood May H.
Published: April 2023

Pregnancy and physiological and psychological variations can impact mental and emotional changes and thereby trigger depression and anxiety in expectant mothers. Being overly concerned about an individual’s financial, social, and health issues can promote depression and anxiety among pregnant women. Managing those associated factors during and after pregnancy is crucial. Although several studies reported depression and anxiety disorder in pregnant women, there are limited studies available in Saudi Arabia. Thus, this study measured the prevalence of both depression and anxiety among pregnant women in Al-Madinah Al-Muawarah, Saudi Arabia. A total of 250 surveys were conducted from five primary care centers randomly. A simple stratified sampling technique was used. General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire (PHQ-9) were used as research instruments for data collection. Of the seven items from GAD-7, the higher rate related to the response “not at all” for the following items; “Being so restless that it is hard to sit still” by 165 (66.5%) was obtained followed by “Becoming easily annoyed or irritated” 118 (47.2%). Similarly, from the nine items from the PHQ-9, the higher rate response was obtained with “not at all” for the following items; “Thoughts that you would be better off dead, or hurting yourself” by 243 (98.0%), followed the second-highest rate was obtained regarding “Several Days” for the following items; “Trouble falling or staying asleep, or sleeping too much” by 116 (46.8%). The current study is consistent with previous studies.
An Unguided, Computerized Cognitive Behavioral Therapy Intervention (TreadWill) in a Lower Middle-Income Country: Pragmatic Randomized Controlled Trial (Preprint)
Authors: Ghosh Arka , Cherian Rithwik J , Wagle Surbhit , Sharma Parth , Kannan Karthikeyan R , Bajpai Alok , Gupta Nitin
Published: April 2023

BACKGROUND

Globally, most individuals who are susceptible to depression do not receive adequate or timely treatment. Unguided computerized cognitive behavioral therapy (cCBT) has the potential to bridge this treatment gap. However, the real-world effectiveness of unguided cCBT interventions, particularly in low- and middle-income countries (LMICs), remains inconclusive.

OBJECTIVE

In this study, we aimed to report the design and development of a new unguided cCBT–based multicomponent intervention, TreadWill, and its pragmatic evaluation. TreadWill was designed to be fully automated, engaging, easy to use, and accessible to LMICs.

METHODS

To evaluate the effectiveness of TreadWill and the engagement level, we performed a double-blind, fully remote, and randomized controlled trial with 598 participants in India and analyzed the data using a completer’s analysis.

RESULTS

The users who completed at least half of the modules in TreadWill showed significant reduction in depression-related (P=.04) and anxiety-related (P=.02) symptoms compared with the waitlist control. Compared with a plain-text version with the same therapeutic content, the full-featured version of TreadWill showed significantly higher engagement (P=.01).

CONCLUSIONS

Our study provides a new resource and evidence for the use of unguided cCBT as a scalable intervention in LMICs.

Authors: Tolks Daniel , Schmidt Johannes Jeremy , Kuhn Sebastian
Published: April 2023

BACKGROUND

Artificial intelligence (AI) and game-based methods such as serious games or gamification are both emerging technologies and methodologies in health care. The merging of the two could provide greater advantages, particularly in the field of therapeutic interventions in medicine.

OBJECTIVE

This scoping review sought to generate an overview of the currently existing literature on the connection of AI and game-based approaches in health care. The primary objectives were to cluster studies by disease and health topic addressed, level of care, and AI or games technology.

METHODS

For this scoping review, the databases PubMed, Scopus, IEEE Xplore, Cochrane Library, and PubPsych were comprehensively searched on February 2, 2022. Two independent authors conducted the screening process using Rayyan software (Rayyan Systems Inc). Only original studies published in English since 1992 were eligible for inclusion. The studies had to involve aspects of therapy or education in medicine and the use of AI in combination with game-based approaches. Each publication was coded for basic characteristics, including the population, intervention, comparison, and outcomes (PICO) criteria; the level of evidence; the disease and health issue; the level of care; the game variant; the AI technology; and the function type. Inductive coding was used to identify the patterns, themes, and categories in the data. Individual codings were analyzed and summarized narratively.

RESULTS

A total of 16 papers met all inclusion criteria. Most of the studies (10/16, 63%) were conducted in disease rehabilitation, tackling motion impairment (eg, after stroke or trauma). Another cluster of studies (3/16, 19%) was found in the detection and rehabilitation of cognitive impairment. Machine learning was the main AI technology applied and serious games the main game-based approach used. However, direct interaction between the technologies occurred only in 3 (19%) of the 16 studies. The included studies all show very limited quality evidence. From the patients’ and healthy individuals’ perspective, generally high usability, motivation, and satisfaction were found.

CONCLUSIONS

The review shows limited quality of evidence for the combination of AI and games in health care. Most of the included studies were nonrandomized pilot studies with few participants (14/16, 88%). This leads to a high risk for a range of biases and limits overall conclusions. However, the first results present a broad scope of possible applications, especially in motion and cognitive impairment, as well as positive perceptions by patients. In future, the development of adaptive game designs with direct interaction between AI and games seems promising and should be a topic for future reviews.

Published: April 2023

BACKGROUND

Psychosocial well-being, which assesses emotional, psychological, social, and collective well-being, could help measure risk and duration of sick leave in workers.

OBJECTIVE

This study aims to build a structural equation model of a Psychosocial Well-Being Index based on 10 psychosocial factors and investigate its association with sick leave.

METHODS

Data of workers using Wittyfit was collected in 2018. Psychosocial factors (job satisfaction, atmosphere, recognition, work-life balance, meaning, work organization, values, workload, autonomy, and stress) were self-assessed using health-related surveys, while sick leave records were provided by volunteer companies.

RESULTS

A total of 1,399 workers were included in the study (mean age: 39.4±9.4, mean seniority: 9.2±7.7, 49.8% of women, 12.0% managers). The prevalence of absenteeism was 34.5%, with an average of 8.48±28.7 days of sick leave per worker. Structural equation modelling facilitated computation of workers’ psychosocial well-being index (AIC: 123,016.2, BIC: 123,231.2, RMSEA: 0.03). All factors, except workload (p=.9), were influential, with meaning (β=0.72, 95% CI 0.69 to 0.74), values (0.69, 0.67 to 0.70) and job satisfaction (0.64, 0.61 to 0.66) being the main drivers (P<.001). Overall, psychosocial well-being was found to be a protective factor for sick leave, with a 2% decreased risk (OR=0.98, 95% CI 0.98 to 0.99, P<.001) and duration (IRR=0.98, 95% CI 0.97 to 0.99, P<.001) per psychosocial well-being index point.

CONCLUSIONS

The psychosocial well-being index provides a measure of psychosocial well-being and helps predict sick leave in the workplace. This new indicator could be used to analyze the association between psychosocial well-being and other health outcomes.

Assessing Patient-Reported Outcomes in Routine Cancer Clinical Care Using Electronic Administration and Telehealth Technologies: Realist Synthesis of Potential Mechanisms for Improving Health Outcomes (Preprint)
Authors: Govindaraj Ramkumar , Agar Meera , Currow David , Luckett Tim
Published: April 2023

BACKGROUND

The routine measurement of patient-reported outcomes in cancer clinical care using electronic patient-reported outcome measures (ePROMs) is gaining momentum worldwide. However, a deep understanding of the mechanisms underpinning ePROM interventions that could inform their optimal design to improve health outcomes is needed.

OBJECTIVE

This study aims to identify the implicit mechanisms that underpin the effectiveness of ePROM interventions and develop program theories about how and when ePROM interventions improve health outcomes.

METHODS

A realist synthesis of the literature about ePROM interventions in cancer clinical care was performed. A conceptual framework of ePROM interventions was constructed to define the scope of the review and frame the initial program theories. Literature searches of Ovid MEDLINE, Ovid Embase, Scopus, and CINAHL, supplemented by citation tracking, were performed to identify relevant literature to develop, refine, and test program theories. Quality appraisal of relevant studies was performed using the Mixed Methods Appraisal Tool.

RESULTS

Overall, 61 studies were included in the realist synthesis: 15 (25%) mixed methods studies, 9 (15%) qualitative studies, 13 (21%) descriptive studies, 21 (34%) randomized controlled trials, and 3 (5%) quasi-experimental studies. In total, 3 initial program theories were developed regarding the salient components of ePROM interventions—remote self-reporting, real-time feedback to clinicians, and clinician-patient telecommunication. The refined theories posit that remote self-reporting enables patients to recognize and report symptoms accurately and empowers them to communicate these to clinicians, real-time feedback prompts clinicians to manage symptoms proactively, and clinician-patient telephone interactions and e-interactions between clinic encounters improve symptom management by reshaping how clinicians and patients communicate. However, the intervention may not achieve the intended benefit if ePROMs become a reminder to patients of their illness and are not meaningful to them and when real-time feedback to clinicians lacks relevance and increases the workload.

CONCLUSIONS

The key to improving health outcomes through ePROM interventions is enabling better symptom reporting and communication through remote symptom self-reporting, promoting proactive management of symptoms through real-time clinician feedback, and facilitating clinician-patient interactions. Patient engagement with self-reporting and clinician engagement in responding to feedback are vital and may reinforce each other in improving outcomes. Effective ePROM interventions might fundamentally alter how clinicians and patients interact between clinic encounters.

Published: April 2023

Os efluentes ricos em metais são muito comuns e geram grande preocupação, pois, embora estes elementos sejam encontrados facilmente na natureza, eles encontram-se em concentrações muito pequenas. Assim, a partir das ações antrópicas, os metais acabam sendo dispostos em ambientes onde não seriam facialmente encontrados e em concentrações elevadas, de modo que é necessário que esses poluentes sejam tratados de forma adequada e sustentável. Existem diversos métodos para remoção de metais, sendo eles químicos, físicos e biológicos. A adsorção de metais é um dos métodos de tratamento mais utilizados para remoção de metais do meio líquido devido a sua simplicidade, facilidade de operação e bom custo-benefício, principalmente se o adsorvente utilizado for abundante. O processo de adsorção, quando utiliza um adsorvente biológico, é chamado de biossorção/bioacumulação, que, além das vantagens já citadas, amplia as possibilidades com o uso de resíduos orgânicos, organismos vivos ou mortos ou outro material de baixo custo. O objetivo da presente revisão é realizar um levantamento a respeito da remoção de metais por biossorção e bioacumulação. Os processos conhecidos como biossorção e bioacumulação ganharam muito destaque nas últimas duas décadas devido a bons resultados de remoção e recuperação dos íons metálicos. Atualmente, são utilizados diversos tipos de biossorventes, como resíduos orgânicos provenientes dos segmentos industriais, justamente por ser um setor que produz resíduo em abundância. Além dos resíduos, plantas e micro-organismos também são bastante empregados nos processos de remoção de metais. A biomassa fúngica, viva ou morta, tem um papel muito importante nesse processo de tratamento. Por possuírem uma ótima capacidade de adsorção dos metais em meio aquoso e, quando se trata de biomassa viva, pode ser levada em consideração a sua versatilidade e capacidade de resistir e se adaptar a diferentes concentrações de metais. Adicionalmente, o metabolismo no processo de bioacumulação pode ser uma ferramenta a mais no processo de tratamento. Os gêneros Aspergillus e Penicillium são uns dos mais empregados para remoção de diversos metais isolados ou em coquetéis, tendo eficiências de remoção que, segundo os trabalhos observados, puderam variar entre 28 a 99%. Neste sentido, é importante o estudo e seleção de cepas fúngicas capazes de promover a remoção de diversos metais em diferentes concentrações, com a intenção de reduzir os impactos causados por efluentes contaminados com metais.
