Introduction: Knee arthrodesis following failed total knee arthroplasty is a viable limb salvage option, and this procedure is reserved for failed two-stage revision surgery in severe comorbid patients with irreparable extensor mechanism disruption, severe instability, and extensive soft tissue loss. Knee arthrodesis using a dual-plate construct has been scarcely reported. We report a case of knee arthrodesis using a dual-plate construct in a male in his 20s who presented to us with a broken distal femur megaprosthesis. Case Report: An anterior midline incision was given. The cement mantle and broken prosthetic components were removed. The bone surfaces were freshened up and fixed using two orthogonal locking plates. After 4 months, there was a solid fusion in the knee, and the patient started walking independently with a short limb gait. The patient was advised limb lengthening for a shortening of 3 cm, but he denied it and managed with a shoe raise. After 4 years, he was pain free, and radiographs revealed a solid knee fusion. The patient was fully satisfied with the procedure, and he resumed manual work. Conclusion: This case report revealed that knee arthrodesis using a dual-plate construct is an economically viable salvage option for failed distal femur megaprosthesis. Keywords: Megaprosthesis, broken, knee arthrodesis, dual plating.

Introduction: We encountered a unique case of a patient with two distinct tumors coexisting in the same thigh. To the best of our knowledge, this combination of tumors in the same anatomical region has not been previously described in the literature. Case Report: This case report describes a 38-year-old Caucasian male with a painless mass in his right thigh, which was later diagnosed as a hybrid tumor composed of low-grade fibromyxoid sarcoma and sclerosing epithelioid fibrosarcoma, as well as a second tumor, which was diagnosed as a hibernoma. The patient underwent neoadjuvant chemotherapy and surgical excision, followed by adjuvant radiotherapy and treatment for metastatic recurrence. Conclusion: The rarity of this case highlights the need for interdisciplinary collaboration and further investigations into the behavior and management of hybrid tumors. This case also underscores the importance of an accurate histological diagnosis aided by immunohistochemistry and molecular analyses. Keywords: Evan’s tumor, fibromyxoid sarcoma, sclerosing epithelioid fibrosarcoma, metastasis, hibernoma, soft-tissue tumors, sarcoma.

Introduction: Abnormalities of the double-layered meniscus are rare and can be difficult to diagnose. The main pathology in this abnormality, which is predominantly seen in the lateral compartment, is an accessory meniscus lying over the normal meniscus. Anatomically, this structure can appear in different forms. Although other meniscal abnormalities associated with a double-layered meniscus have been reported, this case presents a previously undescribed type in the literature. Case Report: A 12-year-old girl presented to our clinic with complaints of knee locking and pain. When the patient underwent arthroscopy, an accessory incomplete discoid meniscus was found overlying the normal lateral meniscus. We performed an excision of the upper accessory meniscus and the patient had no problems during 3 years of follow-up after surgery. Conclusion: Abnormalities of the lateral meniscus are rare and can be difficult to diagnose. In cases where we suspect a meniscal abnormality, a proper arthroscopic examination should be performed and if a discoid meniscus is seen, it should be considered that this may be a double-layered meniscus. Keywords: Double-layered meniscus, discoid meniscus, lateral meniscus abnormalities, knee arthroscopy.

Introduction: Malignant tumors afflicting the sub-condylar area and ascending ramus of the mandible without mucosal involvement are extremely rare. Traditional approaches such as lip-split-cheek flap and Visor flap would prove sub-optimal and excessive for such limited lesions and entail salivary contamination and mental nerve sacrifice. To circumvent these limitations, we developed a surgical approach that achieves wide, extra-oral exposure to the condyle and ascending ramus and permits controlled resection, affording protection to the facial nerve branches and mental nerve, while avoiding salivary contamination. Cases: The main features of the approach include a pre-auricular skin crease incision extendable both ways, trans-parotid dissection with protection of facial nerve branches, and controlled bony resection. In all cases, monobloc resection was possible with preservation of the uninvolved facial nerve branches, avoidance of salivary contamination, and prompt healing. Conclusion: An extra-oral non-mucosal surgical approach is described for highly selected cases of mandibular resection. Keywords: Facial nerve, mandible, parotid gland, resections, non-mucosal.

Introduction: Ewing sarcoma (ES) is a malignant and aggressive bony tumor affecting the most common age group of 5–20 years. It constitutes 10%–15% of all bone sarcomas and is the second most common primary malignant bone tumor after osteosarcoma. It usually presents with pain, which is typically constant and progressive in nature. The primary source of pain is due to the instability of the spine to support the weight of the body, the vertebral body’s expanding cortices due to the growing mass, compression of nerve roots due to tumor mass, pathologic fractures, spinal cord compression, and invasion of tissue by the tumor mass. Methods: We reviewed the literature on Ewing’s Sarcoma of the spine to evaluate its etiology, clinical presentations, differential diagnosis, imaging modalities, and management with chemotherapy, radiotherapy, and surgical management. PubMed, EMBASE, Google Scholar, and Cochrane key articles were searched. Keywords such as “Ewing’s Sarcoma,” “Spine,” “etiology,” “treatment,” “surgical management,” and “en bloc resection” were used. Discussion: The current management of Ewing’s sarcoma of the spine usually involves three primary modalities: combination chemotherapy, surgery and/or radiotherapy. Recent improvements in combination chemotherapy (vincristine, doxorubicin, cyclophosphamide±ifosfamide, and etoposide) are among the most significant factors for improving survival. Furthermore, recent advancements in radiotherapy, instrumentation, and fusion techniques in surgical management have been demonstrated to improve local disease control and overall survival. Conclusion: Primary ES of the spine is a rare condition affecting the most common age group of 5–20 years, accounting for 1–3 cases/million/year. About 5% of cases have spine involvement. Recent improvements in combination chemotherapy have improved the overall survival rates. En bloc resection and/or radiotherapy have improved local control of the disease. Keywords: Ewing’s sarcoma, spine, etiology, treatment, surgical management, en bloc resection.
‘Shooting in the dark’: implications of the research–practice gap for enhancing research use in adult social care
Authors: Gray Karen , Dibsdall Lisa , Sumpter Linda , Cameron Ailsa , Willis Paul , Symonds Jon , Jones Matthew , McLeod Hugh , Macdonald Geraldine , Cabral Christie
Published: March 2024

Background:

Despite calls for greater use of research and an appetite to do so within adult social care, a gap persists between research and practice.

Aims and objectives:

To explore views of adult social care staff about research and its application to everyday practice. To understand how these might impact upon research use capacity-building initiatives within adult social care organisations.

Methods:

Thematic analysis of semi-structured qualitative interviews with 25 staff members working within the adult social care departments of three English local authorities.

Findings:

Participants characterised research as feeling separate from practice. They reflected on their use of it in relation to pressures affecting adult social care and identified a lack of relevant research. Research benefiting service users, supporting individual practice or informing organisational decision-making was considered useful. However, research could also be viewed as a luxury where its findings were felt to represent an ‘ideal’ rather than real world of practice or did not accord with practice knowledge or local experience.

Discussion and conclusions:

While participants feel positively towards research, there remains a gap between these perceptions and its use in practice. There remains a need to improve research relevance and accessibility and to clarify its role in decision-making in social care, including where there is no evidence, where evidence challenges existing practice, or where the evidence base is growing. Collaborative partnerships between adult social care organisations, researchers and service users could help to narrow the research–practice gap and support the routine translation of research to practice.
What Went Wrong In Hungary
Authors: Anghel Veronica , Jones Erik
Published: March 2024

Abstract: Why did Hungarian democracy have a harder time developing and rooting itself than democracy in other countries? The answer lies in the overlapping institutions and incentives that create democratic resilience. Hungary's political elites never finished their constitutional transition from communism to democracy by agreeing on a new democratic constitution. The 1998 elections polarized Hungarian politics around competing conceptions of democracy in ways that made it hard to reach consensus on a shared constitutional arrangement. Viktor Orbán and his Fidesz party rose to power in the late 1990s by offering a strong state that would protect Hungarian society from the threat of social liberalism and foreclose a potential return of communism. Orbán returned to power in 2010, on the heels of the global financial crisis, and began centralizing and entrenching power by deft manipulation of democratic institutions. The case of Hungary tells us what to look for in anticipating democratic failure and serves as a cautionary tale for the EU.
East-Central Europe: The Young and The Far-Right
Authors: Jakli Laura
Published: March 2024

Abstract: Scholars are increasingly concerned that youth political apathy is a risk to liberal democracy. The issue of youth apathy is particularly pronounced in East-Central Europe—a region that has recently experienced sharp democratic decline. Across the EU member states of East-Central Europe, the share of youth that report complete disinterest in politics has doubled in the last decade. This is not an artifact of youth dissatisfaction with their nation's democracy. Rather, it is explained by ideological cross-pressures. East-Central Europe's apathetic youth hold a unique set of values that do not map onto party platforms. Unlike older generations, they are profoundly pro-EU and embrace certain aspects of liberalism, including gay rights. They are also significantly less religious. However, they are increasingly unfriendly toward immigration and multiculturalism. Compared to their politically engaged peers, East-Central Europe's apathetic youth also value democratic governance less. If they were to be politically mobilized, there is little reason to believe they would stabilize liberal democracy.
Why Autocracies Fear LGBTQ+ Rights
Authors: Pauselli Gino , Urzúa María-José
Published: March 2024

Abstract: During the past decades, the rights of sexual minorities have been subject to both expansion and resistance at domestic and international levels. This essay investigates the resistance to sexual orientation and gender identity (SOGI) rights by focusing on the position of autocratic regimes in international organizations. It examines the history and evolution of discussions regarding SOGI within the United Nations (UN) and presents an analysis of the positions taken by countries in all SOGI resolutions adopted by the UN Human Rights Council (UNHRC). Democracies and autocracies are clearly divided on the topic of LGBTQ+ rights, with the latter vehemently opposing proposals to expand sexual minorities' rights. This autocratic resistance is rooted in fears of empowered minorities challenging the status quo and the perceived threat of SOGI rights as a gateway to broader liberal values. By leveraging cultural anxieties and joining forces with other nondemocratic regimes, autocracies exploit traditional values to resist the expansion of international liberal norms. The United Nations must adopt policy recommendations aimed at countering opposition to SOGI rights by emphasizing the universality of human rights, combating cultural relativism, and reframing the national sovereignty argument to garner broader support for SOGI rights.
Thomas Aquinas in Intellectual Formation: Philosophy
Authors: Gorman Michael
Published: March 2024

Abstract: In light of the newly-published sixth edition of the Program of Priestly Formation, and other ecclesial documents, this essay offers reflections on philosophy's role in seminary formation. It discusses the value of requiring seminarians to study philosophy at all, and the value of requiring them to study St. Thomas's philosophy in particular. Philosophy prepares a priest to study theology, but it aids his pastoral ministry in ways that go well beyond this. The paper also addresses dangers involved with putting an emphasis on St. Thomas.
A study on the purchase intention of luxury goods from the perspective of face perception and expected regret
Authors: Wei Jiahua , Shen Hong , Lu Zhizeng
Published: March 2024

The study on the impact of consumer purchase intention on luxury goods has received widespread attention from the academic community. This study collected research data in Guilin, China, through questionnaire survey, and conducted an empirical study on the influencing factors of luxury consumers’ purchase intention. The results show: The price level of luxury goods has a positive impact on consumers’ face perception, while the positive impact of price level on expected regret has not been verified. Consumer’s face perception has positive and negative effects on consumers’ expected regret and consumers’ purchase intention respectively. Consumer’s downward expected regret and consumer’s upward expected regret have different effects on consumers’ purchase intention. Consumers’ face perception and expected regret play a mediating effect in the research of influence relationship. This study is conducive to a better analysis of the psychology and behavior of Chinese luxury consumers, enriching the theoretical connotation of consumer psychology, and promoting the healthy development of the luxury goods industry.
Repeatability of Pentacam-derived intraocular lens decentration measurements and the level of agreement with OPD-Scan III: A prospective observational case series
Authors: Liu Xiaobao , Wu Wenjie , Huang Yulong , Fu Yabo , Huang Yue , Li Qiong
Published: March 2024

Purpose

This study aimed to assess the repeatability of intraocular lens (IOL) decentration measurements obtained through Pentacam, based on corneal topographic axis (CTA) and pupillary axis (PA), and to evaluate the level of agreement between Pentacam and OPD-Scan III devices in measuring IOL decentration.

Methods

In this prospective observational case series, three measurements were performed with Pentacam to evaluate the repeatability of the measurements. The analysis included the calculation of the mean and standard deviations (SD), conducting a repeated measures analysis of variance (rANOVA), and determining an intraclass correlation coefficient (ICC) to assess the repeatability of the measurements. Moreover, Bland-Altman analysis was employed to assess the agreement between Pentacam and OPD-Scan III devices in measuring IOL decentration. IOL decentration measurements were obtained with respect to both CTA and PA.

Results

A total of 40 eyes from 40 patients were analyzed. The rANOVA revealed no significant difference among three consecutive measurements of IOL decentration obtained with Pentacam. The mean SD of all parameters ranged from 0.04 mm to 0.07 mm. With CTA as the reference axis, the ICC values for Pentacam measurements of IOL decentration were 0.82 mm for the X-axis, 0.76 mm for the Y-axis, and 0.82 mm for spatial distance. When using PA as the reference axis, the corresponding ICC values were 0.87, 0.89, and 0.77, respectively. The 95% limits of agreement for all IOL decentration measurements were wide when comparing Pentacam and OPD-Scan III.

Conclusions

Pentacam demonstrated high repeatability in measuring IOL decentration with respect to both CTA and PA. However, due to poor agreement between Pentacam and OPD-Scan III measurements, caution should be exercised when using data interchangeably between the two devices.
Ultra short term power load forecasting based on the fusion of Seq2Seq BiLSTM and multi head attention mechanism
Authors: Gou Yuanfang , Guo Cheng , Qin Risheng
Published: March 2024

Ultra-short-term power load forecasting is beneficial to improve the economic efficiency of power systems and ensure the safe and stable operation of power grids. As the volatility and randomness of loads in power systems, make it difficult to achieve accurate and reliable power load forecasting, a sequence-to-sequence based learning framework is proposed to learn feature information in different dimensions synchronously. Convolutional Neural Networks(CNN) Combined with Bidirectional Long Short Term Memory(BiLSTM) Networks is constructed in the encoder to extract the correlated timing features embedded in external factors affecting power loads. The parallel BiLSTM network is constructed in the decoder to mine the power load timing information in different regions separately. The multi-headed attention mechanism is introduced to fuse the BiLSTM hidden layer state information in different components to further highlight the key information representation. The load forecastion results in different regions are output through the fully connected layer. The model proposed in this paper has the advantage of high forecastion accuracy through the example analysis of real power load data.

Published: March 2024

Machine learning (ML) algorithms can handle complex genomic data and identify predictive patterns that may not be apparent through traditional statistical methods. They become popular tools for medical applications including prediction, diagnosis or treatment of complex diseases like rheumatoid arthritis (RA). RA is an autoimmune disease in which genetic factors play a major role. Among the most important genetic factors predisposing to the development of this disease and serving as genetic markers are HLA-DRB and non-HLA genes single nucleotide polymorphisms (SNPs). Another marker of RA is the presence of anticitrullinated peptide antibodies (ACPA) which is correlated with severity of RA. We use genetic data of SNPs in four non-HLA genes (PTPN22, STAT4, TRAF1, CD40 and PADI4) to predict the occurrence of ACPA positive RA in the Polish population. This work is a comprehensive comparative analysis, wherein we assess and juxtapose various ML classifiers. Our evaluation encompasses a range of models, including logistic regression, k-nearest neighbors, naïve Bayes, decision tree, boosted trees, multilayer perceptron, and support vector machines. The top-performing models demonstrated closely matched levels of accuracy, each distinguished by its particular strengths. Among these, we highly recommend the use of a decision tree as the foremost choice, given its exceptional performance and interpretability. The sensitivity and specificity of the ML models is about 70% that are satisfying. In addition, we introduce a novel feature importance estimation method characterized by its transparent interpretability and global optimality. This method allows us to thoroughly explore all conceivable combinations of polymorphisms, enabling us to pinpoint those possessing the highest predictive power. Taken together, these findings suggest that non-HLA SNPs allow to determine the group of individuals more prone to develop RA rheumatoid arthritis and further implement more precise preventive approach.
Monitoring the after-effects of ischemic stroke through EEG microstates
Authors: Wang Fang , Yang Xue , Zhang Xueying , Hu Fengyun
Published: March 2024

Background and purpose

Stroke may cause extensive after-effects such as motor function impairments and disorder of consciousness (DoC). Detecting these after-effects of stroke and monitoring their changes are challenging jobs currently undertaken via traditional clinical examinations. These behavioural examinations often take a great deal of manpower and time, thus consuming significant resources. Computer-aided examinations of the electroencephalogram (EEG) microstates derived from bedside EEG monitoring may provide an alternative way to assist medical practitioners in a quick assessment of the after-effects of stroke.

Methods

In this study, we designed a framework to extract microstate maps and calculate their statistical parameters to input to classifiers to identify DoC in ischemic stroke patients automatically. As the dataset is imbalanced with the minority of patients being DoC, an ensemble of support vector machines (EOSVM) is designed to solve the problem that classifiers always tend to be the majority classes in the classification on an imbalanced dataset.

Results

The experimental results show EOSVM get better performance (with accuracy and F1-Score both higher than 89%), improving sensitivity the most, from lower than 60% (SVM and AdaBoost) to higher than 80%. This highlighted the usefulness of the EOSVM-aided DoC detection based on microstates parameters.

Conclusion

Therefore, the classifier EOSVM classification based on features of EEG microstates is helpful to medical practitioners in DoC detection with saved resources that would otherwise be consumed in traditional clinic checks.

Published: March 2024

Entomological sampling and storage conditions often prioritise efficiency, practicality and conservation of morphological characteristics, and may therefore be suboptimal for DNA preservation. This practice can impact downstream molecular applications, such as the generation of high-throughput genomic libraries, which often requires substantial DNA input amounts. Here, we use a practical Tn5 transposase tagmentation-based library preparation method optimised for 96-well plates and low yield DNA extracts from insect legs that were stored under sub-optimal conditions for DNA preservation. The samples were kept in field vehicles for extended periods of time, before long-term storage in ethanol in the freezer, or dry at room temperature. By reducing DNA input to 6ng, more samples with sub-optimal DNA yields could be processed. We matched this low DNA input with a 6-fold dilution of a commercially available tagmentation enzyme, significantly reducing library preparation costs. Costs and workload were further suppressed by direct post-amplification pooling of individual libraries. We generated medium coverage (>3-fold) genomes for 88 out of 90 specimens, with an average of approximately 10-fold coverage. While samples stored in ethanol yielded significantly less DNA compared to those which were stored dry, these samples had superior sequencing statistics, with longer sequencing reads and higher rates of endogenous DNA. Furthermore, we find that the efficiency of tagmentation-based library preparation can be improved by a thorough post-amplification bead clean-up which selects against both short and large DNA fragments. By opening opportunities for the use of sub-optimally preserved, low yield DNA extracts, we broaden the scope of whole genome studies of insect specimens. We therefore expect these results and this protocol to be valuable for a range of applications in the field of entomology.
The end of Mexico–US migration as we knew it – or back to the future?
Authors: Hernández-León Rubén , Sandoval Efrén
Published: March 2024

Over the last decade, scholars have declared the collapse of the Mexico–US system of undocumented migration. The H2 visa programme, a regime of managed sojourning is replacing the system of unauthorized cross-border mobility. In fiscal year 2023, the US government issued nearly 370,000 H2 temporary work visas to Mexicans. This temporary migrant labour programme is also bringing back circulation, temporary legal stays, and mostly male cross-border mobility – features that are akin to the old Bracero Program (1942–64). We contend that the restoration of these legal and sociodemographic dynamics undermines critical pillars of the system of undocumented labour mobility, limiting and reorienting the role of social networks, and potentially ending the way Mexico–United States has functioned for the past half century. We use ethnographic, interview and survey data to analyse the expansion of this new regime of highly mediated cross-border mobility, the ascent of the brokerage apparatus, and its effect transforming the social infrastructure of migration. We ask, specifically, how does the H2 temporary migrant labour programme constrain and diminish kin and hometown-based social networks, previously seen as ‘the engine of migration’? How does the shift from migrant networks to a brokerage apparatus impact trust, reciprocity and the development of migratory social capital? How is the new regime changing the experience of migration – substituting risk and adventure for certainty and routinized movement? How does the H2 temporary migrant labour programme revert the locus of social reproduction of the labour force back to sending communities, preempting integration at the destination? We frame the answers to these questions in the emerging migration industry and infrastructures paradigm, which examines to the role of migrant and non-migrant actors in the facilitation, control and overall mediation and structuring of cross-border mobility.
Inclusive virtual simulation space: Digital technologies and design thinking process
Authors: See Zi Siang , Matthews Benjamin , Day Jamin , Carroll Nicole , McGrath Jack , Amin Manisha
Published: March 2024

This article demonstrates a case study in research-creation based on the extended reality (XR) placemaking initiative, and reports on the development of two iterations that are part of a digital technologies (DT) project. Various studies with a focus on restorative and relaxation applications have shown positive findings in improving mental wellness and self-awareness. We speculate that combining physical activity and exposure to digital nature can provide additional health benefits compared to restorative activities alone. The first iteration, Mind Space XR, is a virtual reality (VR) project that has the initial goal of supporting users to experience emotion-focused skills training based on mindfulness, emotion regulation and compassion in a low-risk environment. In this iteration of the DT project, we have focused on interaction design aspects and the research-creation process required to develop the information architecture framework of an early prototype. This ongoing research then informs the development of a second iteration, the ‘inclusive virtual simulation space’ – a VR learning simulation initiative that supports users to experience customizable content in an inclusive environment. Combining Australian Curriculum areas from DT and the humanities and social sciences, this study will experiment with the human–computer interaction process with the goal of configuring a modular high-fidelity virtual environment to achieve perceived ease of use by user groups including creators, educators and students. This will lead to a proof-of-concept platform with the flexibility to integrate digital content that permits the co-creation of digital prototypes driven by inclusive virtual and physical placemaking and simulation learning. This educational inclusive virtual simulation project focuses on experimenting with and introducing education technology and XR skills and knowledge to educators and creators, which is broadly applicable to education-based DT contexts.
olhar para dentro: A perspectiva identitária em a cor da ternura, de Geni Guimarães
Authors: Gomes de Lima Emanuelle Valéria , Nogueira Marinho Maria Simone
Published: March 2024

A trajetória da Literatura infanto-juvenil no Brasil é marcada por uma homogeneidade estética que pouco condiz com a diversidade e a plurietnicidade existente no país. Há, portanto, uma disparidade de produções que elencam em seus enredos temáticas como racismo, sexismo etc. O cenário apenas começa a se modificar, especialmente, a partir dos anos 1990 e após a promulgação de Leis, como as Leis Federais 10.639/2003, alterada para 11. 645/2008, ambas com o objetivo de disseminar a História e as Culturas africanas, afrodescendentes e indígenas na Educação Básica brasileira. Leis estas, que se constituíram após pressão dos movimentos negros. Os efeitos da luta democrática de inserção do segmento negro e feminino se dá também no mercado editorial que, por longo período, dificultou a publicação das escritas marginalizadas, sobretudo, no campo infanto-juvenil. Portanto, esse estudo visa analisar a obra mirim A cor da Ternura, de Geni Guimarães, mulher preta e pobre, que sobreviveu ao meio social racista e misógino, desenvolvendo um olhar para dentro de si mesma, que transborda em uma literatura sensível e lúdica. Através das perspectivas de autores como Hall (2002), hooks (2019), Kilomba (2019), entre outros, é que analisamos, sob a ótica da construção da identidade negra, a protagonista da obra, também denominada Geni.

Jornadas de Junho de 2013 e sua dispersão pelo Brasil
Authors: Barbosa Gisele Heloise
Published: March 2024

O presente trabalho tem por objetivo analisar o grau de dispersão dos manifestantes pelo Brasil durante as Jornadas de Junho de 2013 a partir de dados estatísticos relativos à quantidade de manifestantes. Os dados foram coletados do Portal G1 e organizados pelos dias em que compareceram às ruas, mostrando o aumento em volume dos protestos até o pico, dia 20 de junho, e a posterior queda. Constatou-se que o grau de dispersão das Jornadas de Junho de 2013 pelo Brasil foi bastante elevado, principalmente no dia 20/06, por ter ocorrido nas capitais e no interior dos estados. Apesar de muitos estudos sobre os protestos terem se concentrado no Sudeste, a porcentagem de manifestantes em relação à população total mostra que outras capitais tiveram números expressivos no dia 20, mas uma repercussão menor nas redes sociais. Isso pode indicar a existência de dinâmicas políticas locais relacionadas aos desdobramentos ideológicos e eleitorais na década subsequente.

INTRODUÇÃO: O enxerto de tecido conjuntivo subepitelial associado ao retalho de avanço coronal é considerado a terapia padrão-ouro para tratamento de retrações gengivais; porém, essa técnica pode apresentar limitações devido à anatomia da raiz do dente, resultando na falta de espaço necessário para a cicatrização do enxerto. OBJETIVO: Relatar um caso clínico utilizando a técnica de biomodulação tecidual, por odontoplastia radicular, para criar um novo perfil de emergência, em tratamento em duas etapas, visando proporcionar mais espaço e formação de tecido gengival, favorecendo o recobrimento radicular cirúrgico. RELATO DE CASO: Paciente do sexo feminino, 18 anos de idade, encaminhada por um ortodontista, compareceu ao projeto de extensão em Periodontia Clínica e Cirúrgica da Universidade Federal de Campina Grande (PROEPECC/UFCG), queixando-se de retração gengival. Na avaliação, o dente #41 apresentava retração do Tipo 1, associada a inserção anormal do freio labial, com 3 mm de altura e 2 mm de largura, 2 mm de profundidade de sondagem e ausência de gengiva inserida. A paciente foi submetida a biomodulação mucogengival, com desgaste seletivo mínimo na superfície radicular. Após a realização de dois desgastes, constatou-se recobrimento radicular de 83,3% e ganho de mucosa ceratinizada. Realizou-se a cirurgia de cobertura radicular com a técnica de enxerto de tecido conjuntivo subepitelial combinado com retalho de avanço coronal, além da frenectomia labial. Após 1 ano, a retração foi totalmente recoberta e houve um aumento de 1 mm de mucosa ceratinizada. CONCLUSÃO: A técnica mostrou-se eficaz em modificar as características morfológicas do tecido ao redor do defeito mucogengival, melhorando o prognóstico de tratamento da retração gengival.

Introdução: Existe uma lacuna na literatura sobre o protocolo mais eficaz para remoção do hidróxido de cálcio (HC) associado a diferentes veículos em áreas de reabsorção radicular interna (RRI). Objetivo: Avaliar a performance da irrigação ultrassônica passiva (PUI), XP-Endo Finisher e Easy Clean na remoção do HC em áreas de RRI simuladas, utilizando pastas associadas a diferentes veículos. Métodos: Canais radiculares de 128 incisivos inferiores foram preparados até o instrumento de calibre 30 e seccionados longitudinalmente para criar cavidades de RRI, usando brocas diamantadas esféricas. Em seguida, os canais foram preenchidos com pasta Ultracal XS (UC) ou HC PA associado com propilenoglicol, e distribuídos em dois grupos controle positivo (n = 4) e seis grupos experimentais, de acordo com o protocolo de remoção (n = 20): PUI (G1 e G4), Easy Clean (G2 e G5) e XP-Endo Finisher (G3 e G6). Os canais foram irrigados com NaOCl 2,5% e EDTA 17%. Todas as RRIs foram fotografadas usando câmera digital montada em estereomicroscópio. Dados foram coletados por um sistema de escores e analisados pelo teste de Kruskal-Wallis (α = 0,05). Resultados: Nas RRI do terço médio, a remoção foi melhor no G4 (PA PUI), comparada aos grupos Ultracal XS. No terço apical, houve melhor remoção no G4 (PA PUI) e G6 (PA XP), comparados aos grupos G1 (UC PUI) e G3 (UC XP) (p < 0,05). Conclusão: Nenhum dos dispositivos testados removeu completamente as pastas de HC, entretanto, demonstraram performance similar na remoção de pastas com mesmo veículo, sugerindo a influência desse na remoção.
Efeito da aplicação do laser Er:YAG na rugosidade superficial e na resistência de união ao arrancamento de pinos de fibra de vidro com dois designs diferentes: estudo in vitro
Authors: Abohajar Salam Ahmad
Published: March 2024

Objetivos: Avaliar a rugosidade superficial (RS) e a resistência de união (RU) de pinos de fibra cilíndricos e pinos com dupla conicidade pré-tratados com laser Er:YAG. Métodos: A amostra foi dividida em quatro grupos experimentais (n = 10): Grupo A – pinos com dupla conicidade e ranhuras verticais, irradiados com laser; Grupo B – controle; Grupo C – pinos cilíndricos, irradiados com laser; e Grupo D – controle. Um perfilômetro foi utilizado para medir a RS dos pinos antes e após a aplicação do Er:YAG. Foram selecionados 40 pré-molares inferiores unirradiculares, distribuídos aleatoriamente e, em seguida, os canais radiculares foram obturados e os espaços para os pinos foram preparados. Os pinos de fibra foram cimentados nos canais radiculares nos quatro grupos. Depois que todos os corpos de prova foram preparados, os ensaios de arrancamento (pull-out) foram realizados com uma máquina universal de testes. Os dados foram analisados usando ANOVA e teste post-hoc (α=0,05). Resultados: Os dois grupos de pinos de fibra irradiados com Er:YAG apresentaram valores médios de RS maiores do que os grupos controle. A RU dos pinos cilíndricos irradiados com laser foi maior do que no grupo controle (p<0,05). O mesmo resultado foi encontrado nos pinos com dupla conicidade (A e B). Os grupos com pinos irradiados apresentaram aumento na RU ao arrancamento, quando comparados aos grupos controle (p<0,05), enquanto houve diferença não significativa observada nas demais comparações pareadas entre os grupos (p>0,05). Conclusões: A resistência de união e a rugosidade superficial dos pinos de fibra de vidro foram amplamente melhoradas pelo pré-tratamento com laser Er:YAG e não foram afetadas pelo design do pino de fibra.

Background: Newborns mostly require breast milk. Women who choose to work are equally responsible for maintaining breastfeeding. Prior studies have identified variations in the time and intensity of breastfeeding before and after returning to work. Disparities exist in the assistance provided for women to breastfeed in the workplace, with past studies revealing insufficient facilities. This study intends to examine women's views on the support for breastfeeding in the workplace.Method: A scoping review was carried out using the PubMed, Google Scholar, and ScienceDirect databases, following PRISMA procedures. The papers were selected based on specific criteria: they had to be cross-sectional and qualitative studies focusing on women's opinions of breastfeeding in the workplace. Additionally, the articles were to be written in English, give the entire text, and have been done between 2019 and 2023.Results: Ten publications were examined from different workplaces. The research examines different forms of work and workplaces. Women's views on breastfeeding support focus on instrumental support, such as inappropriate or unavailable lactation rooms, work hours and policies, lack of breastfeeding groups, facilities for breastfeeding and breast milk pumping, insufficient storage, inadequate childcare facilities, and lack of caregivers at home, which impede exclusive breastfeeding. Emotional support refers to the assistance provided by colleagues in the workplace. Form of information support, namely the absence of communication and information support. There is a common belief that breastfeeding is seen as a personal issue connected to one's knowledge and self-confidence. Cross-sectoral collaboration needs to be involved, including family, workplace commitment, and government support to support the success of breastfeeding in the workplace.

Background: Hand Foot Mouth Disease (HFMD) is an acute infectious disease. The epidemic of HFMD has been reported in some countries in the Pacific region, every three years in America, and almost every year in China. This study is conducted to determine risk factors that correlate with HFMD in children under five years old in Dusun Sengkrakan, Lawang. This study is a cross-sectional study with an analytical observational approach.Method: The sample size was determined by total sampling, including 54 mothers with children under five years old in Dusun Sengkrakan, Lawang. The result was then analyzed with a statistical package for the social science (SPSS).Results: This study shows that there is a significant correlation between children’s age (p = 0.012) and HFMD occurrence, meanwhile, sex, birth weight, gestational age, exclusive breastfeeding, number of siblings in the house, and mother’s age have no significant correlation with HFMD occurrence. Children's age is the most dominant factor among other independent variables [p = 0.017; OR 2.849 (95% CI: 1.203 – 6.750)]. The result of this study is expected to raise public awareness of promotive and preventive measures against HFMD for the public purpose of preventing HFMD outbreaks in Indonesia

Published: March 2024

Background: Health cadres play a crucial role in community development, serving as primary health managers responsible for mobilizing communities and fostering self-help initiatives to improve health outcomes. Despite their significance, challenges such as poor communication leading to missed visits by mothers with toddlers hinder program execution. Understanding and addressing these challenges is essential for establishing a resilient healthcare system that optimizes cadre contributions.Method: A qualitative, phenomenological approach was employed in this study. In-depth interviews were conducted with 11 diverse participants, including the Head of the Public Health Center, the Coordinator of Health Cadres, Health Cadres, and Community Members. Informant selection utilized purposive techniques and snowball sampling, with an interview guide containing open-ended questions as the research instrument. The data analysis followed a descriptive approach based on the Miles and Huberman model.Results: Challenges faced by health cadres varied across regions, encompassing factors such as differing community participation levels, heavy administrative tasks, and conflicts among cadres. Despite these challenges, most cadres exhibited high commitment, motivation, and familial support, mitigating potential issues. Each cadre adopted a unique approach to anticipate and address challenges associated with their roles. Regular coaching from Public Health Centers and implementing simplified administrative systems were identified as potential strategies to enhance cadre performance.

Diferenciace učebního úkolu jako princip rozvoje inkluzivního přístupu k žákům v primárním vzdělávání
Authors: Semrádová Monika
Published: March 2024

Výzkum se zaměřuje na aktuální trend zvyšování kvality vzdělávání, který přináší zvýšené nároky na kompetence učitele při zavádění diferencované výuky u žáků primárního stupně, a to od samého počátku školní docházky. Při výuce matematiky se učitelé setkávají s nejrůznějšími postoji žáků k řešení zadávaných úloh a způsoby osvojování si nových vědomostí a dovedností. Nicméně, mnozí učitelé k tomu nejsou dostatečně připraveni a relevantní odbornéliteratury a výzkumných šetření, které by jim v praxi pomohly, je velmi málo. Záměrem výzkumné studie je analýza pedagogických prostředků diferenciace učebního úkolu a analýza aspektů rozsahu, obsahu, obtížnosti a časového hlediska zadávaných úkolů v předmětu matematika u žáků primárního stupně základní školy, s ohledem na Bloomovu taxonomii vzdělávacích cílů. Na několika případových studiích učitelů z Pardubického, Hradeckého a Středočeského kraje představujeme, na základě příkladů dobré praxe, jaké aspekty diferenciace učebního úkolu v předmětu matematika a geometrie učitelé využívají v heterogenních kolektivech žáků.
