What is the best procedure for determining removal rate coefficients in horizontal flow treatment wetlands: influent and effluent concentrations or longitudinal concentration profiles?
Authors: von Sperling Marcos , Wallace Scott D. , Nivala Jaime
Published: May 2023

First-order removal rate coefficients (k) are used in predictive equations for estimating effluent concentrations from horizontal flow (HF) wetlands. Due to limited resources, influent and effluent concentration data from existing systems are frequently used in the estimation of k values from operating systems, but another choice is to use concentration data along the longitudinal profile of the HF wetland. Based on a dataset with 41 HF wetlands/studies obtained from a literature survey, with chemical oxygen demand (COD) measurements at different sampling points, volumetric (kV) and areal (kA) removal rate coefficients for the Tanks-In-Series (TIS) model have been obtained using the two estimation methods. In general, removal rate coefficients derived from longitudinal profiles of concentrations were higher than those obtained by using data from influent and effluent concentrations, reflecting the fact that constituent removal is mostly accomplished before the wastewater reaches the outlet zone. Deriving coefficients from longitudinal profiles is more comprehensive, providing a better explanation of the internal removal taking place in the treatment wetland. However, the more widely used approach of calculating kV and kA from influent/effluent concentrations may lead to a safer design of horizontal flow wetlands, because of underestimation of the actual removal rate coefficients.

Published: May 2023

Currently, the main cause of cancer chemotherapy failure is multi-drug resistance (MDR),
which involves a variety of complex mechanisms. Compared with traditional small-molecule chemotherapy,
targeted nanomedicines offer promising alternative strategies as an emerging form of therapy,
especially active targeted nanomedicines. However, although single-targeted nanomedicines have made
some progress in tumor therapy, the complexity of tumor microenvironment and tumor heterogeneity
limits their efficacy. Dual-targeted nanomedicines can simultaneously target two tumor-specific factors
that cause tumor MDR, which have the potential in overcoming tumor MDR superior to single-targeted
nanomedicines by further enhancing cell uptake and cytotoxicity in new forms, as well as the effectiveness
of tumor-targeted delivery. This review discusses tumor MDR mechanisms and the latest achievements
applied to dual-targeted nanomedicines in tumor MDR.

Lebanese Women: A Cross-sectional Study
Authors: Bouclaous Carmel , Albaini Obey , Bou Malham Melissa , Salem Marie-Josée , Deeb Mary , Al Ghadban Faten
Published: May 2023

Introduction:

Cervical cancer can be prevented through vaccination against HPV and routine
screening through HPV DNA testing or Pap smear. This cross-sectional study aimed to assess functional
cervical cancer literacy (FCCL) levels and correlates among women of reproductive age in Lebanon.

Methods:

The Arabic self-administered questionnaire consisted of the Cervical Cancer Literacy Assessment Tool, socio-demographic characteristics (age, education, employment status, religiosity, ability to pay), and health-related factors (smoking, parity, chronic diseases, self-perceived health, history
of uterine or cervix surgeries, health insurance, visits to physician in the past three months, and regular
Pap smear and HPV DNA testing).

Results:

Of 619 women mean age of 33.9 years (±12.0), 51.7% had insufficient FCCL. Lower educational level, difficulty in covering medical expenses, lack of health insurance and poor self-perceived
health were significantly associated with insufficient FCCL. Multiple logistic regression analysis
showed that monthly income (OR: 1.74 [95% CI: 1.12 – 2.72]), ability to pay for medical expenses
(OR: 1.81 [1.05 – 3.14]), and visits to the doctor in the last three months (OR: 1.51 [1.07 – 2.12]) were
predictive of FCCL level

Conclusion:

In addition to a national vaccination program against HPV combined with cervical cancer
screening, we recommend the inclusion of cervical cancer as a topic within sexuality education programs.
Special attention should be given to women with limited FCCL and uninsured women of low socioeconomic status. To enhance cervical cancer literacy, and promote vaccination and screening, efforts
should extend beyond health care settings and leverage various media channels, including social media.
An Overview of Protein Function Prediction Methods: A Deep Learning
Perspective
Authors: Ispano Emilio , Bianca Federico , Lavezzo Enrico , Toppo Stefano
Published: May 2023

Predicting the function of proteins is a major challenge in the scientific community, particularly
in the post-genomic era. Traditional methods of determining protein functions, such as experiments,
are accurate but can be resource-intensive and time-consuming. The development of Next Generation
Sequencing (NGS) techniques has led to the production of a large number of new protein sequences,
which has increased the gap between available raw sequences and verified annotated sequences.
To address this gap, automated protein function prediction (AFP) techniques have been developed as
a faster and more cost-effective alternative, aiming to maintain the same accuracy level.

:

Several automatic computational methods for protein function prediction have recently been developed
and proposed. This paper reviews the best-performing AFP methods presented in the last decade and
analyzes their improvements over time to identify the most promising strategies for future methods.

:

Identifying the most effective method for predicting protein function is still a challenge. The Critical
Assessment of Functional Annotation (CAFA) has established an international standard for evaluating
and comparing the performance of various protein function prediction methods. In this study, we analyze
the best-performing methods identified in recent editions of CAFA. These methods are divided into
five categories based on their principles of operation: sequence-based, structure-based, combined-based,
ML-based and embeddings-based.

:

After conducting a comprehensive analysis of the various protein function prediction methods, we observe
that there has been a steady improvement in the accuracy of predictions over time, mainly due to
the implementation of machine learning techniques. The present trend suggests that all the bestperforming
methods will use machine learning to improve their accuracy in the future.

:

We highlight the positive impact that the use of machine learning (ML) has had on protein function prediction.
Most recent methods developed in this area use ML, demonstrating its importance in analyzing
biological information and making predictions. Despite these improvements in accuracy, there is still a
significant gap compared with experimental evidence. The use of new approaches based on Deep
Learning (DL) techniques will probably be necessary to close this gap, and while significant progress
has been made in this area, there is still more work to be done to fully realize the potential of DL.

Published: May 2023

Light energy directly affects microalgae growth and productivity. Microalgae in
natural environments receive light through solar fluxes, and their duration and distribution
are highly variable over time. Consequently, microalgae must adjust their photosynthetic
processes to avoid photo limitation and photoinhibition and maximize yield. Considering
these circumstances, adjusting light capture through artificial lighting in the main culture
systems benefits microalgae growth and induces the production of commercially important
compounds. In this sense, this review provides a comprehensive study of the role of light
in microalgae biotechnology. For this, we present the main fundamentals and reactions of
metabolism and metabolic alternatives to regulate photosynthetic conversion in microalgae
cells. Light conversions based on natural and artificial systems are compared, mainly
demonstrating the impact of solar radiation on natural systems and lighting devices, spectral
compositions, periodic modulations, and light fluxes when using artificial lighting systems.
The most commonly used photobioreactor design and performance are shown herein,
in addition to a more detailed discussion of light-dependent approaches in these photobioreactors.
In addition, we present the principal advances in photobioreactor projects, focusing
on lighting, through a patent-based analysis to map technological trends. Lastly, sustainability
and economic issues in commercializing microalgae products were presented.

Published: May 2023

The use of membrane technology has developed rapidly since the proposal of the Robeson
upper bound. Nevertheless, the researchers proposed various methods and techniques to enhance the
permeability and selectivity to achieve a breakthrough of the upper bound. Metal-organic framework
(MOF) and covalent organic framework (COF) were the recently-interest- arising materials enhancing
gas separation performance. In this study, recent advances in MOF and COF were comprehensively
discussed in terms of the materials, properties and synthesis method. Later, the MOF and COF nanocomposite
mixed matrix membrane development was discussed to evaluate the recent improvement of
these membranes used in the O2/N2 gas separation performance. This work intends to overview the recent
progress and development of the metal-organic framework, covalent organic frameworks and the
used nanocomposite membrane in O2/N2 gas separation. This topic review was carried out from a
thorough literature review of metal-organic frameworks, covalent organic frameworks and the used
nanocomposite membrane in O2/N2 gas separation. Additionally, the recent achievement of the O2/N2
gas separation by nanocomposite membrane in term of permeability and selectivity are also discussed.
Findings from this study suggested that MOF and COF-based nanocomposite membranes could be
used in either the O2/N2 and N2/O2 gas separation process with the possibility of being involved in the
gas production sector.

Human-to-Computer Interactivity Features Incorporated Into Behavioral Health mHealth Apps: Systematic Search
Authors: Collier Ann Futterman , Hagemann Shelby , Trinidad Susan Brown , Vigil-Hayes Morgan
Published: May 2023

Background

While there are thousands of behavioral health apps available to consumers, users often quickly discontinue their use, which limits their therapeutic value. By varying the types and number of ways that users can interact with behavioral health mobile health apps, developers may be able to support greater therapeutic engagement and increase app stickiness.

Objective

The main objective of this analysis was to systematically characterize the types of user interactions that are available in behavioral health apps and then examine if greater interactivity was associated with greater user satisfaction, as measured by app metrics.

Methods

Using a modified PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) methodology, we searched several different app clearinghouse websites and identified 76 behavioral health apps that included some type of interactivity. We then filtered the results to ensure we were examining behavioral health apps and further refined our search to include apps that identified one or more of the following terms: peer or therapist forum, discussion, feedback, professional, licensed, buddy, friend, artificial intelligence, chatbot, counselor, therapist, provider, mentor, bot, coach, message, comment, chat room, community, games, care team, connect, share, and support in the app descriptions. In the final group of 34 apps, we examined the presence of 6 types of human-machine interactivities: human-to-human with peers, human-to-human with providers, human-to–artificial intelligence, human-to-algorithms, human-to-data, and novel interactive smartphone modalities. We also downloaded information on app user ratings and visibility, as well as reviewed other key app features.

Results

We found that on average, the 34 apps reviewed included 2.53 (SD 1.05; range 1-5) features of interactivity. The most common types of interactivities were human-to-data (n=34, 100%), followed by human-to-algorithm (n=15, 44.2%). The least common type of interactivity was human–artificial intelligence (n=7, 20.5%). There were no significant associations between the total number of app interactivity features and user ratings or app visibility. We found that a full range of therapeutic interactivity features were not used in behavioral health apps.

Conclusions

Ideally, app developers would do well to include more interactivity features in behavioral health apps in order to fully use the capabilities of smartphone technologies and increase app stickiness. Theoretically, increased user engagement would occur by using multiple types of user interactivity, thereby maximizing the benefits that a person would receive when using a mobile health app.
Remote Home Monitoring of Continuous Vital Sign Measurements by Wearables in Patients Discharged After Colorectal Surgery: Observational Feasibility Study
Authors: Leenen Jobbe P L , Ardesch Vera , Patijn Gijsbert
Published: May 2023

Background

Hospital stays after colorectal surgery are increasingly being reduced by enhanced recovery and early discharge protocols. As a result, postoperative complications may frequently manifest after discharge in the home setting, potentially leading to emergency room presentations and readmissions. Virtual care interventions after hospital discharge may capture clinical deterioration at an early stage and hold promise for the prevention of readmissions and overall better outcomes. Recent technological advances have enabled continuous vital sign monitoring by wearable wireless sensor devices. However, the potential of these devices for virtual care interventions for patients discharged after colorectal surgery is currently unknown.

Objective

We aimed to determine the feasibility of a virtual care intervention consisting of continuous vital sign monitoring with wearable wireless sensors and teleconsultations for patients discharged after colorectal surgery.

Methods

In a single-center observational cohort study, patients were monitored at home for 5 consecutive days after discharge. Daily vital sign trend assessments and telephone consultations were performed by a remote patient-monitoring department. Intervention performance was evaluated by analyzing vital sign trend assessments and telephone consultation reports. Outcomes were categorized as “no concern,” “slight concern,” or “serious concern.” Serious concern prompted contact with the surgeon on call. In addition, the quality of the vital sign data was determined, and the patient experience was evaluated.

Results

Among 21 patients who participated in this study, 104 of 105 (99%) measurements of vital sign trends were successful. Of these 104 vital sign trend assessments, 68% (n=71) did not raise any concern, 16% (n=17) were unable to be assessed because of data loss, and none led to contacting the surgeon. Of 62 of 63 (98%) successfully performed telephone consultations, 53 (86%) did not raise any concerns and only 1 resulted in contacting the surgeon. A 68% agreement was found between vital sign trend assessments and telephone consultations. Overall completeness of the 2347 hours of vital sign trend data was 46.3% (range 5%-100%). Patient satisfaction score was 8 (IQR 7-9) of 10.

Conclusions

A home monitoring intervention of patients discharged after colorectal surgery was found to be feasible, given its high performance and high patient acceptability. However, the intervention design needs further optimization before the true value of remote monitoring for early discharge protocols, prevention of readmissions, and overall patient outcomes can be adequately determined.

Authors: Østervang Christina , Jensen Charlotte Myhre , Coyne Elisabeth , Dieperink Karin B , Lassen Annmarie
Published: May 2023

BACKGROUND

A lack of information during an emergency visit leads to the experience of powerlessness for patients and their family members, who may also feel unprepared to cope with acute symptoms. The ever-changing nature and fast-paced workflow in the emergency department (ED) often affect how health care professionals can tailor information and communication to the needs of the patient.

OBJECTIVE

This study aimed to evaluate the usability and experience of a newly developed information system. The system was developed together with patients and their family members to help provide the information needed in the ED.

METHODS

We conducted a mixed methods study consisting of quantitative data obtained from the System Usability Scale questionnaire and qualitative interview data obtained from purposively selected participants included in the quantitative part of the study.

RESULTS

A total of 106 patients and 14 family members (N=120) answered the questionnaire. A total of 10 patients and 3 family members participated in the interviews. Based on the System Usability Scale score, the information system was rated close to excellent, with a mean score of 83.6 (SD 12.8). Most of the participants found the information system easy to use and would like to use it again. The participants reported that the system helped them feel in control, and the information was useful. Simplifications were needed to improve the user experience for the older individuals.

CONCLUSIONS

This study demonstrates that the usability of the information system is rated close to excellent. It was perceived to be useful as it enabled understanding and predictability of the patient’s trajectory in the ED. Areas for improvement include making the system more usable by older individuals. The study provides an example of how a technological solution can be used to diminish the information gap in an ED context.

Abstract: Chatbots are computer programs that use text or voice-based interfaces to replicate human conversation. They are often used to automate mundane processes, provide customer support, or aid in the retrieval of information. Chatbots are built with a number of strategies that enable them to interpret and respond to user inputs in a more human-like manner. They can be employed in a variety of industries, including e-commerce, healthcare, and banking. We have analysed and compared numerous chatbot strategies in this report to establish the optimal way for our own chatbot project. We reviewed twenty-six papers on chatbot development and assessed the advantages and disadvantages of various strategies. Natural language processing techniques, such as tokenization and named entity recognition, have been shown in our research to be critical for interpreting user inputs. We also discovered that dialogue management methods, such as rule-based and machine learning-based approaches, have an important influence in influencing discussion flow. Furthermore, we discovered that natural language generation techniques, such as template-based and neural network-based methods, are critical in generating effective chatbot responses. We also investigated various services on the market in order to create a functional chatbot for our college. We also emphasized the various applications of chatbots as well as the current hurdles in the industry. Based on these findings, we chose a technique for our own chatbot project that employs advanced natural language processing and machine learning techniques to create more human-like conversations and improve overall user experience.
The Effects of Authoritarian and Transformational Leadership on In-Role Performance: The Moderating Role of Power Distance Orientation and Time-with-Leader
Authors:   Korean Academy of Leadership, Zhu Xue , Chae Yeon Joo
Published: May 2023

Focusing on recent trends in leadership research, this study tries to identify the effectiveness of authoritarian leadership by comparing effects of authoritarian with transformational leadership on in-role performance. Furthermore, this study investigates the conditions that limit effectiveness of two leadership styles positing power distance orientation and time-with-leader as moderating variables. In particular, although the time-with-leader is not widely known as a critical variable in leadership research, it needs to be discussed in leadership studies considering the reality of less face-to-face contact with leaders due to the telecommuting (eg. working at home). Based on the responses of 224 office workers in China, this study revealed that authoritarian and transformational leadership are positively related to in-role performance. Also, both power distance orientation and time-with-leader have significant positive moderating effects on the relationship between authoritarian leadership and in-role performance. On the contrary, in the case of transformational leadership, both moderating effects have been rejected. This study has a significance in that there are few studies comparing authoritarian and transformational leadership despite advances in leadership research. In addition, it also has a significance in introducing a variable, time-with-leader, which has not been considered as a major variable in leadership research.

Published: May 2023

This study aims to examine the effects of organizational factor(interactional justice) that alleviate deviant behavior, and investigate the mediating effects of personal factors (psychological ownership and work engagement) in the relationship between interactional justice and deviant behavior. A survey was conducted of members with a working tenure of 6 months or longer in general business organization, and 292 responses were analyzed. Prior to hypothesis testing, descriptive statistics, correlation, and reliability were verified through SPSS 21.0, and the fitness of the research model was confirmed with AMOS 21.0. Lastly, to verify the hypothesis, analysis was performed through structural equation modeling and bootstrapping. The results of the study were as follows. First, it was confirmed that interactional justice had a positive effect on psychological ownership. Second, psychological ownership had a positive effect on work engagement. Third, work engagement was not significantly related to counterfeit, withdrawal, verbally hostile behavior, but had a negative effect on production deviance. Finally, psychological ownership and work engagement partially mediated the relationship between interactional justice and deviant behavior.
Specifically, psychological ownership and work engagement only mediated the relationship between interactional justice and production deviance. Based on the results, the practical implications such as organizational support and HRD program were offered.
The Effect of Psychological Contract Breach by Subordinates on Job Burnout of middle managers Focusing on the Serial Multiple Mediation of Role overload and Job Stress
Authors:   Korean Academy of Leadership, Kim Sunam , Tak Je Woon
Published: May 2023

Middle managers carry out the pivotal task of implementing the organization's strategies and policies, establishing roles expected of their subordinates, and managing performance. However, through the recent generational change, members of the organization have become clearer in their individualistic tendencies, place a high value on work-life balance, and their perspective on work has also changed from 'live to work' to 'work to live'.
Paradoxically, under the same situation in which the amount of work to be performed in a limited time and the level of performance are the same, the work expected to be performed by the members is transferred to the middle manager, who has to perform both member’s job and managerial roles at the same time. As a result, they are complaining of job burnout, depression, and helplessness. In other words, today's middle managers are faced with a situation in which they have to fulfill their duties and achieve their goals while recognizing the breach of the psychological contract in which the promises and obligations that members consider to be provided to the organization are not kept.
Therefore, if existing studies have mainly focused on the effect on members when an organization breaches its psychological contract, In this study, approached from the perspective of when employees did not fulfill their psychological contractual obligations, the effect of psychological contract breach by subordinates on job burnout (emotional burnout) of middle managers and the serial multiple mediating effect of role overload and job stress in the process were verified. To test the hypothesis, an online survey was conducted targeting middle managers working in domestic companies, and the response data of 371 people were used for analysis. As a result of the analysis, first, psychological contract breach by subordinates was found to have a positive (+) relationship with emotional exhaustion of middle managers. Second, there was no mediating effect of role overload between psychological contract breach by subordinates and emotional exhaustion. Third, the mediating effect of job stress between psychological contract breach by subordinates and emotional exhaustion was found to have a positive (+) significant effect. Fourth, between psychological contract breach by subordinates and emotional exhaustion, role overload and job stress showed a positive serial multiple mediating effect.
This study identified that the psychological contract breach by subordinates was an antecedent factor affecting emotional burnout of middle managers, and verified the mechanisms of role overload and job stress between independent and dependent variables. Based on the results of this study, theoretical and practical implications were presented, and the limitations of the study and future research directions were discussed.
O que cada um pode jogar: “jogo do osso”, cultura popular e a construção social do delito no Rio Grande do Sul (1940-1950)
Authors: De Loyola Érico Teixeira
Published: May 2023

O artigo aborda, a partir da prática recreativa denominada “jogo do osso”, as potenciais hierarquias socialmente estabelecidas em torno do lazer, capazes de configurá-lo, a depender das circunstâncias e dos sujeitos implicados, em atividade benigna ou inadequada, lícita ou ilícita. Tendo como recorte temporal as décadas de 1940 e 1950, e valendo-se de fontes policiais e judiciárias extraídas de processos que tiveram curso em duas localidades do Rio Grande do Sul (Lavras do Sul e Pelotas), almeja-se discutir como as leis penais, e a Lei das Contravenções Penais, em particular, teriam sido instrumentalizadas para o controle de práticas lúdicas associadas às classes populares. Pretende-se, ainda, discutir como os parâmetros legalmente estabelecidos eram excetuados de acordo com as pessoas envolvidas, a partir de uma perspectiva hierarquizadora, justificando, de modo seletivo, a utilização dos aparatos repressivos. Para essa análise, serão tomados como referenciais teóricos as proposições de Pierre Bourdieu em torno do conceito de "distinção" (2007), e os debates estabelecidos por Thompson acerca dos sentidos da “cultura popular” (1998).

Published: May 2023

O objetivo deste trabalho é cotejar a discussão historiográfica sobre as eleições no Brasil Império. Antes de fazê-lo, considerei fundamental discutir como os pleitos da época eram organizados, o que me levou a examinar a legislação eleitoral do período. Durante o Império, a legislação eleitoral foi se tornando cada vez mais complexa. O processo eleitoral chegou a constituir-se de pequenas eleições a cada etapa. Portanto, na primeira parte, para que se consiga dimensionar a importância de cada parte do rito eleitoral e avaliar a pertinência das análises historiográficas sobre as eleições, é preciso perscrutar as leis que as organizavam. O restante do artigo se dedica a estudar aspectos que compunham as eleições que foram pouco discutidos, – a participação eleitoral, a atuação política e a cidadania – juntamente ao enquadramento clássico: o das fraudes.

Escola e democracia
Authors: Nunes Mascarenhas Aline , Moreira de Oliveira Goulart Janaina
Published: May 2023

O presente estudo é uma análise crítica do processo contemporâneo antidemocrático e de autoritarismo em escolas públicas brasileiras, transformando-as de civis em militarizadas e seus desdobramentos na democracia, constituindo um processo de desdemocratização, conceito de Charles Tilly (2013). Empreendem-se problematizações a partir de três categorias analíticas: o militarismo e amilitarização na educação pública; a inter-relação entre escola e democracia; a desdemocratização. Trata-se de um estudo bibliográfico, com análise crítico-interpretativa desse modelo de militarização de escolas, a partir de produções sobre o tema no campo educacional (Santos, 2020; Mascarenhas, 2020; Goulart, 2022) e sobre a inter-relação entre escola pública e democracia (Saviani, 2008; Teixeira, 1977). A análise crítico-interpretativa desvela elementos que induzem à desdemocratização do ensino público,esvaziando os sentidos de uma educação plural, emancipatória, democrática e comprometida com o desenvolvimento de uma consciência política e crítica.

Este trabalho é resultado de uma pesquisa em desenvolvimento à luz do Ciclo das Políticas Públicas, com a finalidade de conhecer o processo da militarização das escolas públicas no Tocantins. A militarização das escolas públicas tem se expandido de maneira interligada ao avanço das ideias neoconservadoras da extrema-direita. No Tocantins, os índices de violência são incompatíveis com oargumento da militarização das escolas como estratégia para conter o aumento da criminalidade, mas verifica-se a expansão desse modelo nas redes de ensino estadual e municipal de Palmas. Foi identificado como o processo de expansão da militarização dessas escolas fere os preceitos de gestão democrática e levantado possíveis impactos nos resultados educacionais, como a queda no Índice de Desenvolvimento da Educação Básica de algumas das escolas militarizadas.

O trabalho com multiletramentos no Ensino Médio configura uma dupla necessidade: atender às normativas da BNCC quanto à modalidade de educação que prevê a formação plena dos estudantes, de forma a prepará-los para a recepção e produção de textos que vão muito além da palavra escrita, além de configurar uma ação coerente com a realidade na qual os estudantes estão inseridos, o que vai ao encontro do que defende a Linguística Aplicada Crítica, que prevê que as ações escolares estejam voltadas para questões práticas e relevantes para a vida da sociedade em geral. Dentre os vários gêneros trabalhados no espaço escolar, visando ao multiletramentos dos estudantes, optamos por investigar o trabalho com o hipergênero ‘quadrinhos’. Propomos, neste artigo, uma pesquisa do tipo ‘estado da arte’, a fim de verificarmos o quanto já se avançou nos estudos pertinentes a essa temática. O referencial teórico ancora-se em autores como Canclini (2019), Jenkins (2009), Rajagopalan (2003), Ramos (2020), Rojo (2012), Vergueiro (2020) e outros. A revisão realizada mostrou que há, por enquanto, poucas publicações acerca da temática pesquisada e que as existentes são bem recentes, o que não causa estranheza, dado o fato de que os quadrinhos eram excluídos do contexto escolar até poucos anos atrás.

Introduction/Objective. More than three years have passed since the discovery of the new virus strain SARS-CoV-2, and the virus is still a challenge for all medical specialties. One of the most important characteristics is the tendency to develop thromboembolic complications, which are often lethal. The aim of this paper is to present the experience of the General Surgery Department of the Zemun Clinical Hospital Centar in the surgical treatment of patients with thromboembolic complications. Methods. The research was conceived as a retrospective study conducted in the period from March 2020 to March 2021. A total of 42 patients participated in the study and were divided into a group diagnosed with small and large bowel ischemia and a group diagnosed with acute limb ischemia. Results. In both groups, males were predominantly represented. The first group consisted of nine patients, all of whom had a clinical finding of acute abdomen and ileus, while seven of them also had a severe computed tomography image of bilateral pneumonia. In the second group, a smaller number of patients were initially candidates for thrombectomy, while in others, primary amputation treatment was approached. Mortality from the underlying disease in both groups was high. Conclusion. Moderate and severe forms of SARS-CoV-2 infection are associated with an inflammatory response leading to endothelial dysfunction accompanied by a high incidence of thromboembolic complications despite pharmacological prophylaxis. The current consensus supports the use of anticoagulants in all hospitalized patients with moderate to severe disease, as well as in critically ill patients.

Objectives

To investigate the association between the width of keratinized gingiva (WKG), gingival phenotype (GP), and gingival thickness (GT) with craniofacial morphology in sagittal and vertical dimensions.

Materials and Methods

WKG, GP, and GT of mandibular anterior teeth in 177 preorthodontic patients (mean age 18.38 ± 5.16 years) were assessed clinically using a periodontal probe, a Colorvue Biotype Probe, and ultrasound by a single examiner. Patients were grouped into skeletal Class I, II, and III and hyperdivergent, normodivergent, and hypodivergent based on ANB and SN-MP angles. Mandibular incisor inclination (L1-NB) was also measured. Clinical and cephalometric measurements were repeated to assess inter- and intraexaminer reproducibility.

Results

A significant association was found between thin GP and skeletal Classes I and III for the left mandibular central incisor (MCI; P = .0183). In skeletal Class III patients, L1-NB angle demonstrated a decreasing trend as phenotype thickness decreased. A significant association was found between thin phenotype and normodivergent and hypodivergent groups for MCIs (left: P = .0009, right: P = .00253). No significant association between WKG or GT and craniofacial morphology was found.

Conclusions

Thin GP is associated with skeletal Class I and III for the left MCI. Thin GP is associated with hypodivergent and normodivergent skeletal patterns for the MCIs. There was no association between WKG and GT and craniofacial morphology in both skeletal and vertical dimensions. Dental compensations that exist due to different craniofacial morphology may influence the GP.

Indonesia

Desde la última actualización de la situación prevaleciente en Indonesia publicada por el Anuario Asia Pacífico han transcurrido casi diez años. En ese lapso, Indonesia ha transitado de la presidencia de Susilo Bambang Yudhoyono, considerada por muchos como decepcionante y por otros como un remanso urgente de estabilidad para el país, al gobierno de Joko Widodo (exgobernador de Yakarta, mejor conocido como “Jokowi”), un personaje carismático que ha promovido la realización de varias reformas necesarias para apuntalar el desarrollo nacional, al tiempo que también se ha mostrado bastante activo en la arena internacional a fin de posicionar a Indonesia como un país cuya voz sea nuevamente un referente en el Sureste de Asia. Durante todo ese tiempo, la economía de Indonesia ha registrado un buen desempeño, al grado que el país es considerado por muchos como una “economía emergente” cuyo peso no puede ser ignorado y a la cual incluso ya se invita regularmente a las reuniones del G-20. No obstante, resulta evidente que el crecimiento sostenido de los índices macroeconómicos del país ha encubierto varias deficiencias estructurales que parecen estar manifestándose como un obstáculo al desarrollo nacional, pues ahora Indonesia no sólo es una nación importadora de petróleo y poseedora de una base productiva especializada en bienes primarios —cuando alguna vez fue exportadora de petróleo y registró una industrialización incipiente—, sino que también es evidente el alto costo presupuestal generado por el mantenimiento de distintas políticas clientelistas cuya aplicación resulta cada vez más insostenible para las finanzas públicas. Además, Indonesia ha debido recuperar la credibilidad como un destino seguro para las inversiones foráneas tras un periodo de fuerte incertidumbre que se remonta a la crisis asiática de 1997, procurando que el proyecto de desarrollo mantenga un equilibrio con el medio ambiente dado el fuerte deterioro causado por la explotación de los recursos de aquel país, degradación ambiental que incluso ya ha provocado problemas entre Indonesia y algunos de sus vecinos. En este contexto, el activismo diplomático del actual presidente no sólo busca posicionar a Indonesia como un país con influencia allende sus fronteras, sino que procura atraer las inversiones requeridas para apuntalar el crecimiento económico nacional en un contexto regional donde ahora resulta ineludible considerar la fuerte competencia económica de China. De esta manera, el gigante del Sureste Asiático atraviesa por un periodo de grandes cambios orientados a fortalecer tanto la base material del país como su presencia internacional, cuyo desenlace, a apenas dos años de iniciado el gobierno de Jokowi, aún resulta incierto dada la magnitud de los escollos pendientes de resolver.
