Authors: Caetano Robert , Bastos Silva Tâmara , Ribeiro de Castro Darcy , Silva Benfica Nayanne
Published: December 2022

Diante da importância do bioma Caatinga, de levantar informações que contribuam com divulgação científica, monitoramento, conservação dos recursos naturais e o planejamento de políticas ambientais, objetivou-se caracterizar a cobertura vegetal e o fluxo de carbono do município de Central – Bahia, que apresenta uma extensa área ocupada por lavouras temporárias, por meio dos índices espectrais NDVI, SAVI, EVI e CO2Flux, para um período seco e um chuvoso de 2020. Foram utilizadas imagens do satélite Sentinel-2, processadas em ambiente SIG. Os resultados demonstraram que o período chuvoso apresentou maiores IV, principalmente NDVI e SAVI, com valores próximos a 1. O EVI chuvoso apresentou valores menores que os índices mencionados, no entanto, ainda superiores aos do período seco, que apresentaram valores predominantemente abaixo de 0,50, com exceção da região que abriga o Riacho Baixão do Gabriel. A área urbana foi bem discriminada nas imagens para o período chuvoso, mas não no seco. Zonas de menor altitude apresentaram maiores valores para os IV, enquanto as de maior altitude tiveram menores valores. O CO2Flux demonstrou que o sequestro de carbono foi mais eficiente no período chuvoso e a correlação entre os IV demonstrou uma relação forte entre eles, principalmente entre o NDVI e SAVI.

Programas Performativos Pandêmicos como registro e continuidade dos processos de criação em dança durante a pandemia
Authors: Gasparini Igor
Published: December 2022

Como artista da dança, diretor do T.F.Style Cia de Dança, este texto surge a partir das experiências artísticas desenvolvidas pelo núcleo desde 2002 e que, nos últimos anos, desdobrou-se no aprofundamento da pesquisa corpo-cidade e de outras possibilidades de mediação obra-público. Em 2020, com a interrupção das ações presenciais, o núcleo teve de encontrar outras formas de continuar a pesquisa em andamento, dividindo suas ações entre grupo de estudos, vivências práticas pela tela e realização de programas performativos, com objetivo de reforçar os ELOs à distância. Se, por um lado, o isolamento social impediu que os artistas continuassem a pesquisa de corpo a corpo, abriu possibilidades de investigação de outras relações com o espaço: o espaço-casa e o espaço-tela. E a pesquisa de corpo em 360º encontrou outros desafios nas telas bidimensionais. Neste momento de isolamento social, são muitas as incertezas para nós artistas da cena. Como cultivar a presença mediada pela tela? Ainda é possível realizar as “artes vivas” em meio a tantas mortes? Como manter os ELOs e a pesquisa em dança neste período de isolamento? Como a experiência de cidade em um contexto pós-pandêmico também transforma nosso fazer? Em março de 2020, quando decidimos pela continuidade dos encontros dessa outra forma, sugeri ao grupo o texto “Programas Performativos: o corpo em experiência”, de Eleonora Fabião, primeiramente, para leitura e discussão, mas que também pudesse estimular a realização de protocolos de criação. Essa iniciativa permaneceu viva ao longo de todo o ano de 2020 e, inspirados pela artista e pesquisadora, surge o blog Programas Performativos Pandêmicos pelo anseio de tornar público parte desses protocolos realizados ao longo da pandemia, além de demarcar historicamente o momento atual e registrar os processos de criação do núcleo durante a pandemia da COVID-19.

Published: December 2022

Background:

Zika virus (ZIKV) remains an important cause of congenital infection, fetal microcephaly, and Guillain-Barré syndrome in the population. In 2016, WHO declared a cluster of microcephaly cases and other neurological disorders reported as a global public health emergency in Brazil. There is still no specific treatment for Zika virus fever, only palliative care. Therefore, there is a need for new therapies against this disease. According to the literature, thiosemicarbazone, phthalimide and thiazole are privileged structures with several biological activities, including antiviral activity against various viruses.

Objective:

Based on this, this work presents an antiviral screening using previously synthesized compounds derived from thiosemicarbazone, phthalimide, and thiazole as new hits active against ZIKV.

Methods:

After synthesis and characterization, all compounds were submitted to Cytotoxicity by MTT and Antiviral activity against ZIKV assays.

Results:

Compounds 63, 64, 65, and 73 exhibited major reductions in the ZIKV title from this evaluation. Compounds 63 (99.74%), 64 (99.77%), 65 (99.92%), and 73 (99.21%) showed a higher inhibition than the standard 6MMPr (98.74%) at the CC20 dose. These results revealed new chemical entities with anti-ZIKV activity.

Conclusion:

These derivatives are promising candidates for further assays. In addition, the current approach brings a new privileged scaffolding, which may drive future drug discovery for ZIKV.

Published: December 2022

Iridoids are secondary plant metabolites that are multitarget compounds active against various diseases. Iridoids are structurally classified into iridoid glycosides and non-glycosidic iri-doids according to the presence or absence of intramolecular glycosidic bonds; additionally, iridoid glycosides can be further subdivided into carbocyclic iridoids and secoiridoids. These monoterpe-noids belong to the cyclopentan[c]-pyran system, which has a wide range of biological activities, including antiviral, anticancer, antiplasmodial, neuroprotective, anti-thrombolytic, antitrypanoso-mal, antidiabetic, hepatoprotective, anti-oxidant, antihyperlipidemic and anti-inflammatory proper-ties. The basic chemical structure of iridoids in plants (the iridoid ring scaffold) is biosynthesized in plants by the enzyme iridoid synthase using 8-oxogeranial as a substrate. With advances in phyto-chemical research, many iridoid compounds with novel structure and outstanding activity have been identified in recent years. Biologically active iridoid derivatives have been found in a variety of plant families, including Plantaginaceae, Rubiaceae, Verbenaceae, and Scrophulariaceae. Iridoids have the potential of modulating many biological events in various diseases. This review highlights the multitarget potential of iridoids and includes a compilation of recent publications on the phar-macology of iridoids. Several in vitro and in vivo models used, along with the results, are also in-cluded in the paper. This paper's systematic summary was created by searching for relevant iridoid material on websites such as Google Scholar, PubMed, SciFinder Scholar, Science Direct, and oth-ers.The compilation will provide the researchers with a thorough understanding of iridoid and its congeners, which will further help in designing a large number of potential compounds with a strong impact on curing various diseases.
Irrigation Efficiency in Banana Crops in the Canary Islands
Authors: Santamarta Juan C. , Machín Noel , Cruz-Pérez Noelia
Published: December 2022

Background:

When planning the use of available water resources and the hydraulic infrastructures needed to make them available to irrigators, it is important to know the water consumption of the different crops. In addition, it is interesting to know the agricultural practices used in each place, since cultural practices in agriculture have an important effect on the flows, when there is no specific study of the water needs of the crop under study.

Methods:

In order to obtain the data, surveys were conducted among irrigators in the area and for the crop to be studied. However, data collection is not a simple task, depending on the characteristics of the irrigation area studied. Irrigation of the plots is not always accounted for individually, or a study of the water needs of the crop has not always been done. In addition, it has been observed that cultural factors affect the way farmers irrigate.

Results:

The water consumption of banana plantations on the islands of Gran Canaria and Tenerife (Canary Islands) was determined in a field study. The results revealed similar consumption on both islands; however, the island of Gran Canaria showed lower water consumption in terms of banana irrigation. The uniformity coefficient was calculated for the island of Tenerife but not for the island of Gran Canaria, so the results could not be supported by this aspect of the agronomic calculation of irrigation efficiency.

Conclusion:

Knowledge of the agronomic and irrigation practices of the Canary Islands' main crop, bananas, is vital to improve water consumption data in the archipelago, where agriculture is the main water demander. In addition, a series of improvements within the irrigation network, as well as improvement in sustainability practices, such as the introduction of reclaimed water in irrigation on the islands, is considered vital in order to be more efficient with water use in a region so vulnerable to climate change.

Authors: Al-Sutari Manal M. , Abdelkader Raghad H. , Ababneh Nour H.
Published: December 2022

Background

End stage kidney disease (ESKD) requires complex medical management. To ensure the success of management plan, patient’s adherence to medication is fundamental. However, adherence to medication is challenging for patients with ESKD.

Objective

This study aimed to describe adherence to medication and to identify demographic and clinical determinants in Jordanian patients with ESKD.

Methods

Cross-sectional correlational design was performed using a sample of 188 patients with ESKD who attended haemodialysis units in five hospitals in Amman between March and June 2021. Medication adherence was measured using Morisky Medication Adherence Scale (MMAS).

Results

The mean age of the participants was 50.9 years (SD=15.64), more than half of the participants were males 109 (58.0%) and were non-smokers 115 (61.2%). The mean score of the MMAS was 5.18 (SD=2.024) which indicates high prevalence of inadequate adherence to medication. Younger age, longer duration on hemodialysis, and higher number of medications were risk factors for inadequate adherence to medication among patients with ESKD.

Conclusion

ESKD patients who are younger in age, have longer duration on hemodialysis, and have higher number of medications should be targeted as they have medication adherence challenges. Those patients should be taken into consideration when planning and developing interventions to enhance medication adherence in patients with ESKD.

Published: December 2022

The planning of business processes in sea transport is the foundation of transportation companies and technological projects development forecast. The calculations of business processes parameters are mainly complicated by the fact that most of the input values are stochastic ones. This is due to the specifications of technological processes and influence of a wide specter of external environment events (e. g., hydrometeorological and ice conditions) on the one hand, and market conditions (e. g., competition conditions, market agents behavior, exchange rate) on another hand. To provide the necessary level of results reliability, the calculations, that are implemented during research of specifical sea transport operations tasks (such as technological design of seaports), require to pay a great effort in experiments planning. Planning the experiments means the process of choosing the conditions, procedures and methods of experiments running. It also includes the definition of how many experiments should be provided. In other words, the purpose of experiments planning is providing the results maximum precision and reliability with minimum number of experiments. This element of research could take a whole volume in the scientific research. A method for implementing mathematical calculations with stochastic values, which allows you to define the form of the output probability distribution without Monte-Carlo method utilization, is suggested in the paper. It is proved in the paper that the output distribution is close enough to the results, which are calculated with conventional methods. At the same time, when the number of variables is small, the method requires less computational resources.

Se utilizaron como indicadores biogeográficos siete especies de Deltochilina (Anomiopus cirulito, Canthon triangularis, C. lituratus, C. edmondsi, C. morsei, C. angustatus y C. lucreciae), para ejemplificar la influencia de la fauna sudamericana en la diversidad tropical mexicana, buscando explicar por qué México, al sur del Istmo de Tehuantepec, es cada vez más Neotropical. La escala temporal empleada es del fin del Pleistoceno a la época actual y se consideraron tres niveles de información: 1) Penetración con presencia mínima, 2) Penetración con poblaciones marginales y 3) Penetración con poblaciones establecidas. Se ofrecen ejemplos de invasores foráneos que han tenido éxito en lugares ganaderos, sin desplazar a ninguna especie autóctona. Los fenómenos naturales que han condicionado la distribución actual de las especies indicadoras seleccionadas se corresponden con procesos geológicos y macroclimáticos, que influyeron en la composición y los movimientos de las horobiotas a nivel continental. La tendencia de Deltochilini de Centro y Sudamérica por invadir México ha sido muy intensa, empleando el Puente Panameño o incluso el puente inter-Caribe para dispersarse, avanzando con las selvas y, su número supera a las especies incipientes de penetración reciente, de cualquier otro borde de México.

BACKGROUND

The minimum data set (MDS) is a collection of data elements to be grouped using a standard approach to allow the use of data for clinical and research purposes. Health data are typically voluminous, complex, and sometimes too ambiguous to generate indicators that can provide knowledge and information on health. This complexity extends further to the rare disease (RD) domain. MDSs are essential for health surveillance as they help provide services and generate recommended population indicators. There is a bottleneck in international literature that reveals a global problem with data collection, recording, and structuring in RD.

OBJECTIVE

This study aimed to identify and analyze the MDSs used for RD in health care networks worldwide and compare them with World Health Organization (WHO) guidelines.

METHODS

The population, concept, and context methodology proposed by the Joanna Briggs Institute was used to define the research question of this systematic review. A total of 4 databases were reviewed, and all the processes were reported using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology. The data elements were analyzed, extracted, and organized into 10 categories according to WHO digital health guidelines. The quality assessment used the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) checklist.

RESULTS

We included 20 studies in our review, 70% (n=14) of which focused on a specific health domain and 30% (n=6) of which referred to RD in general. WHO recommends that health systems and networks use standard terminology to exchange data, information, knowledge, and intelligence in health. However, there was a lack of terminological standardization of the concepts in MDSs. Moreover, the selected studies did not follow the same standard structure for classifying the data from their MDSs. All studies presented MDSs with limitations or restrictions because they covered only a specific RD, or their scope of application was restricted to a specific context or geographic region. Data science methods and clinical experience were used to design, structure, and recommend a fundamental global MDS for RD patient records in health care networks.

CONCLUSIONS

Our study highlights the difficulties in standardizing and categorizing findings from MDSs for RD because of the varying structures used in different studies. The fundamental RD MDS designed in this study comprehensively covers the data needs in the clinical and management sectors. These results can help public policy makers support other aspects of their policies. We highlight the potential of our results to help strategic decisions related to RD.

The eHealth competence, capabilities, and attitudes of medical students in Finland (Preprint)
Authors: Kautto Mervi , Tuovinen Timo , Kulmala Petri , Reponen Jarmo , Koskela Tuomas H
Published: December 2022

BACKGROUND

Electronic health care (eHealth) services are an increasing part of health care services. The digitalizing health care service system is creating new skills needs and challenges for medical education. Knowledge of students’ competence levels and abilities is important when teaching is being developed.

OBJECTIVE

The aim of this study was to examine the eHealth competencies, abilities, and attitudes of fifth-year medical students in order to develop education to meet the competence needs of the students.

METHODS

A nationwide survey was targeted at all five medical faculties in Finland. An electronic questionnaire was sent to the fifth-year medical students via the faculty administration of each university. In the questionnaire, the responders self-reported their level of competence in regard to the core competencies of eHealth, their capabilities in regard to eHealth, and their attitudes toward eHealth.

RESULTS

187 Finnish medical students responded to the questionnaire regarding eHealth skills, capabilities and attitudes. They self-assessed they had skills in both the use of medical databases (e.g., scientific databases, clinical decision support, electronic counters) and electronic medical-/health-record systems. On the other hand, they assessed themselves as not having enough skills in regard to, for example, carrying out remote consultations or e-consultations.

CONCLUSIONS

Medical students responses revealed that they especially had a skills gap in regard to the applied skills of eHealth. The student’s attitudes toward eHealth were positive, but they felt that the teaching was inadequate in the undergraduate studies related to patient information systems, utilization of the Kanta patient portal, innovation, and communication in the digital environment.

BACKGROUND

Digital loneliness interventions for older adults are promising, yet conclusive evidence is lacking due to a lack of randomized controlled trials (RCTs) and difficulties with recruitment. Process evaluation of performed RCTs is essential to inform future interventions. Still, it is rarely carried out, resulting in an overly optimistic view of the impact of eHealth interventions on loneliness in older adults and options to conduct such research entirely remotely.

OBJECTIVE

We describe a mixed methods process evaluation of a digitally conducted RCT assessing the effectiveness of a mobile social gaming app to facilitate meaningful social interactions in older adults.

METHODS

We analyzed the questionnaire and game data of the RCT participants to evaluate recruitment and onboarding, intervention adherence, and intervention acceptability. The RCT participants were allocated either to the main group of older adults (aged 65 years or older) or the side group (aged between 18 and 64 years). The side group used networking to play with the older adults. We also conducted 6 post-RCT evaluation interviews and 1 focus group with a total of 4 RCT participants and 5 welfare organization representatives that aided in RCT recruitment.

RESULTS

In total, 371 people aged 18 years or older signed up for the RCT, of which 64% (238/371) were aged 65 years or older. Of the total sample, 20% (76/371) installed the app and signed informed consent, showing a large dropout during onboarding. The high number of questions was a relevant barrier for participants. Both questionnaire and gameplay adherence were low. Participants indicated that the games elicited contact and a feeling of togetherness and proposed challenging and competitive games with increasing difficulty levels. They suggested focusing on enjoying the games rather than administering questionnaires.

CONCLUSIONS

Conducting a remote digital trial of a social gaming intervention for older adults is a great challenge. Remote recruitment and informed consent acquisition may often not result in sufficient participation. Personal engagement with fellow participants and researchers might be essential for adherence and enjoyment. Future digital gaming interventions should start with small-scale studies with in-person contact, repeated instructions, and fewer questionnaires.
Digital Microlearning for Training and Competency Development of Older Adult Care Personnel: Mixed Methods Intervention Study to Assess Needs, Effectiveness, and Areas of Application (Preprint)

Published: December 2022

BACKGROUND

Older adult care organizations face challenges today due to high personnel turnover and pandemic-related obstacles in conducting training and competence development programs in a time-sensitive and fit-for-purpose manner. Digital microlearning is a method that attempts to meet these challenges by more quickly adapting to the educational needs of organizations and individual employees in terms of time, place, urgency, and retention capacity more than the traditional competency development methods.

OBJECTIVE

This study aimed to determine if and how an app-based digital microlearning intervention can meet older adult care organizations’ personnel competency development needs in terms of knowledge retention and work performance.

METHODS

This study assessed the use of a digital microlearning app, which was at the testing stage in the design thinking model among managerial (n=4) and operational (n=22) employees within 3 older adult care organizations. The app was used to conduct predetermined competency development courses for the staff. Baseline measurements included participants’ previous training and competency development methods and participation, as well as perceived needs in terms of time, design, and channel. They then were introduced to and used a digital microlearning app to conduct 2 courses on one or more digital devices, schedules, and locations of their own choice during a period of ~1 month. The digital app and course content, perceived knowledge retention, and work performance and satisfaction were individually assessed via survey upon completion. The survey was complemented with 4 semistructured focus group interviews, which allowed participants (in total 16 individuals: 6 managerial-administrative employees and 10 operational employees) to describe their experiences with the app and its potential usefulness within their organizations.

RESULTS

The proposed advantages of the digital microlearning app were largely confirmed by the participants’ perceptions, particularly regarding the ease of use and accessibility, and efficiency and timeliness of knowledge delivery. Assessments were more positive among younger or less experienced employees with more diverse backgrounds. Participants expressed a positive inclination toward using the app, and suggestions provided regarding its potential development and broader use suggested a positive view of digitalization in general.

CONCLUSIONS

Our results show that app-based digital microlearning appears to be an appropriate new method for providing personnel competency development within the older adult care setting. Its implementation in a larger sample can potentially provide more detailed insights regarding its intended effects.
