Role of Injectable Platelet-Rich Fibrin in the Management of Soft and Hard Tissue Periodontal Regeneration in Dentistry: Protocol for a Systematic Review (Preprint)
Authors: Shirbhate Unnati , Bajaj Pavan , Wanjari Mayur , Patil Manoj
Published: January 2025

BACKGROUND

Injectable platelet-rich fibrin (i-PRF) has the capacity to release great amounts of several growth factors, as well as to stimulate increased fibroblast migration and the expression of collagen, transforming growth factor β, and platelet-derived growth factor. Consequently, i-PRF can be used as a bioactive agent to promote periodontal tissue regeneration.

OBJECTIVE

We aim to compare and evaluate the effectiveness of i-PRF in periodontal tissue regeneration.

METHODS

We will conduct an electronic search in the following databases: PubMed, Cochrane Library, Google Scholar, Semantic Scholar, Scopus, and Web of Science. Papers will be restricted to those in English and to those that are randomized controlled trials comparing PRF or any other biomaterial with i-PRF for periodontal regeneration during dental treatment. The included papers in this review and the reference lists of pertinent reviews will be manually searched. The selection of studies, data extraction, and assessment will be carried out separately by 2 reviewers using the Risk of Bias 2 tool for the included research.

RESULTS

The success of i-PRF will be evaluated by comparing the mean difference in periodontal regeneration of soft and hard tissues in terms of gingival recession, probing pocket depth, clinical attachment level, bone gain, and gingival width. The combined effect size measurements and the associated 95% CIs will be estimated using a random-effects model. The synthesis or work for this systematic review started in October 2023 and will last until December 2025.

CONCLUSIONS

i-PRF may play a role in dentistry and could enhance soft and hard tissue regeneration.

Caring Through the Final Phase: A Meta-Synthesis of Family Experiences, Needs and Perceptions in Home-Based Palliative Care for Terminal Cancer Patients. (Preprint)
Authors: Deng Xinming , Hounsri Kanokwan , Lopez Violeta , Tam Wilson Wai-San
Published: January 2025

BACKGROUND

Home-based palliative care is recognised for its benefits in supporting terminal cancer patients during their final stages of life at home. Families play a key role in this care, yet their experiences, needs, and perceptions remain under-researched and lack systematic review.

OBJECTIVE

This review synthesises literature to explore the experiences, needs, and perceptions of families providing home-based palliative care to terminal cancer patients, aiming to identify themes to improve services.

METHODS

This meta-synthesis follows a systematic review of qualitative studies, guided by six steps of qualitative research synthesis. A three-step thematic synthesis was used to derive analytical themes.

Eligibility Criteria
Studies focused on family experiences and perceptions while caring for terminal cancer patients at home were included. Excluded were studies centred solely on patients or healthcare providers.

Information Sources
Databases searched include MEDLINE, EMBASE, SCOPUS, PsycINFO, and grey literature up to 13 September 2023. Two investigators independently screened articles.

Quality Assessment
The Critical Appraisal Skills Programme (CASP) checklist was used to assess quality. Findings were evaluated using the GRADE-CERQual approach, with discrepancies resolved through discussion.

RESULTS

Five studies published between 1989 and 2013, spanning Asian and Caucasian societies, were included. Two main themes emerged: (1) Being physically and emotionally present, and (2) Sharing responsibilities. These themes highlight the essential role of families and the impact of home-based care.

CONCLUSIONS

This meta-synthesis underscores the importance of family involvement in home-based palliative care for terminal cancer patients, supported by hospice teams. Further research is needed to better understand family needs and improve support.
Early Predictive Accuracy of Machine Learning for HT in AIS: A Systematic Review and Meta-Analysis (Preprint)
Authors: Wang Benqiao , Jiang Bohao , Liu Dan , Zhu Ruixia
Published: January 2025

BACKGROUND

Background: Hemorrhagic transformation (HT) is commonly detected in acute ischemic stroke (AIS), and often leads to poor outcomes. Currently, there is no ideal tool for early prediction of HT risk. Recently, machine learning has gained traction in stroke management, prompting the exploration of predictive models for HT. However, systematic evidence on these models is lacking. Therefore, we assessed the predictive capability of machine learning models for HT risk in AIS, aiming to inform the development of HT prediction tools.

OBJECTIVE

Hemorrhagic transformation (HT) is commonly detected in acute ischemic stroke (AIS), and often leads to poor outcomes. Currently, there is no ideal tool for early prediction of HT risk. Recently, machine learning has gained traction in stroke management, prompting the exploration of predictive models for HT. However, systematic evidence on these models is lacking. Therefore, we assessed the predictive capability of machine learning models for HT risk in AIS, aiming to inform the development of HT prediction tools.

METHODS

Methods: We conducted a thorough search of medical databases, such as Web of Science, Embase, Cochrane, and PubMed up until October 2023. The risk of bias was determined through Prediction Model Risk of Bias Assessment Tool (PROBAST). Subgroup analysis was performed based on treatment backgrounds, diagnostic criteria, and types of HT.

RESULTS

Results: Sixty eligible articles were included, containing 69 models and 68678 AIS patients with 6977 HT cases. There were 72 validation sets with a total c-index of 0.822 (95%CI: 0.800-0.844), sensitivity of 0.82 (95%CI: 0.79-0.85), and specificity of 0.77 (95%CI: 0.71-0.82). Subgroup analysis indicated that the combined model achieved superior prediction accuracy. Moreover, we also analyzed the predictive performance of six mature models.

CONCLUSIONS

Conclusions: Currently, although several prediction methods for HT have been developed, their predictive values are not satisfactory. Fortunately, our findings suggest that machine learning methods, particularly those combining clinical features and radiomics, hold promise for improving the predictive accuracy. Our meta-analysis may provide evidence-based guidance for subsequent development of more efficient clinical predictive models for HT.

Competition and regulatory policies interwined: Towards a comprehensive oversight of digital platforms
Authors: Faya Rodríguez Alejandro
Published: January 2025

The digital economy provides a good dose of efficiency and it brings about more benefits than costs. However, nothing guarantees that there will be no further costs or that these benefits will remain over time. A competition deficit in any sector, even more so in the digital economy, requires strong public policy measures and the development of an ecosystem characterized by reasonable contestability. Negative externalities— including privacy issues, consumer rights and misuse of information, among others—should also be controlled through public action. This article first explains how these business models behave differently, as opposed to traditional industries, and considers recent developments in the European and American jurisdictions. It then identifies the challenges ahead and possible solutions from the perspective of both regulatory and competition policies, as complementary measures, while highlighting the balance that must prevail between embracing investments and innovation, and protecting the public interest.
Perspectivas de la gestión medioambiental y su divulgación en micro, pequeñas y medianas empresas
Authors: Flórez-Flórez Claudia Patricia , Loaiza Betancur Edilgardo de Jesús
Published: January 2025

El presente trabajo fue desarrollado con el objetivo de presentar una reflexión sobre el contexto actual y las alternativas que tienen las micro, pequeñas y medianas empresas (mipymes) para adoptar prácticas sostenibles, que a su vez puedan ser comunicadas mediante informes que faciliten la toma de decisiones. Dicha reflexión está fundamentada en el análisis de información que describe alternativas de gestión ambiental empresarial y los instrumentos que son usados para su divulgación. Estas alternativas son el resultado de ejercicios realizadospor diversos autores y organizaciones a nivel internacional, interesados en impulsar estrategias que contribuyan a la sostenibilidad. La investigación es de tipo descriptivo, en la que se hace una revisión documental directa de información recabada de bases de datos académicas. Los resultados obtenidos, que conllevan a la reflexión final reflejan la existencia de una diversidad de opciones que están a disposición de cualquier empresa que quiera acogerse a estrategias orientadas a la gestión ambiental y su divulgación. Dichas estrategias en su mayoría han sido adoptadas solo por empresas de gran tamaño, debido principalmente a que por norma deben llevar a cabo acciones de gestión ambiental que sean informadas. En las mipymes, el panorama es distinto; en este sector se percibe un vacío significativo con respecto a dichas acciones, para lo cual se requiere la implementación de políticas públicas que incentiven un ejercicio amigable con el medioambiente por parte de las empresas de este grupo, y que adicionalmente se promuevan programas de capacitación y sensibilización que conlleven a los dueños de estos negocios a llevar a cabo una gestión integral, mediante la cual se beneficien no solo económicamente, sino también contribuyendo al medioambiente.
Optimizing Memory Efficiency in Large Language Models: Adaptive Compression Techniques
Authors: Chander Dr. T. Prem
Published: January 2025

Large Language Models (LLMs) have revolutionized artificial intelligence by achieving unprecedented results across
various natural language processing (NLP) tasks. However, their massive memory requirements pose significant challenges for
deployment in resource-constrained environments, such as mobile devices and edge computing. This paper introduces an
adaptive compression framework to optimize the memory efficiency of LLMs while maintaining their performance. The proposed
framework integrates multiple techniques, including quantization, pruning, and knowledge distillation, dynamically adjusting
the model size based on specific usage scenarios. Experimental evaluations demonstrate significant reductions in memory usage
with minimal accuracy loss, facilitating the practical deployment of LLMs in real-world applications. The results highlight the
potential for efficient model optimization, paving the way for broader adoption of AI in resource-constrained environments

Objetivo: Conhecer a vivência de adultos jovens com câncer durante a pandemia de COVID-19 e o impacto na sua vida psicoemocional. Metodologia: Pesquisa qualitativa, do tipo estudo de caso, cujos dados foram coletados por meio de entrevista semiestruturada, com adultos jovens que fizeram tratamento oncológico no período de março de 2020 a dezembro de 2021, em um serviço de quimioterapia no sul do Brasil. Os dados foram organizados no software WebQDA, sendo a análise do tipo temática. Resultados: Neste estudo identificou-se que na percepção dos participantes ocorreram poucas alterações no processo de tratamento oncológico durante a pandemia de COVID-19, estando vinculadas ao atraso no início do tratamento e demora das consultas especializadas. Identificou-se ainda a preocupação em contrair o vírus devido à baixa imunidade causada pelo tratamento para o câncer. Além disso, o rigor nas medidas de proteção, como o isolamento causado pela COVID-19, afetou os jovens em tratamento, pois precisaram se afastar de suas funções e ficar longe de suas famílias, o que gerou sentimentos negativos. Conclusões: Pode-se considerar que jovens com câncer no cenário pandêmico necessitam de apoio dos serviços de saúde, principalmente a fim de obterem informações corretas, diagnóstico e tratamento precoce, uma vez que o atraso neste processo pode implicar diretamente na sobrevida dos pacientes. Somado ainda na elaboração de estratégias de cuidado para fornecer a saúde mental para o enfrentamento tanto do câncer quanto da COVID-19.
Az eperjesi evangélikus szellemi központ a 17. században
Authors: Kónya Péter
Published: January 2025

Az eperjesi evangélikus kollégiumot 1665-ben alapították a Felső-Magyarországi rendek kol-légiumaként, speciális feltételek között, a felső-magyarországi (protestáns) rendek akaratából. Az iskola létrehozását a városi tanács áldozatkészsége és együttműködése tette lehetővé, de legalább olyan jelentős szerepet játszottak a kollégium alapításánál a város több mint két és fél évszázados iskolai hagyományai. A tanulmányban az alapítás előzményeit és körülményeit mutatom be, különös tekintettel azon érdekekre és személyekre, személyek csoportjára, ame-lyek közvetlenül garantálták az intézmény anyagi és szellemi bázisát. Közismert, hogy a vizsgált időszakban Felső-Magyarországon koncentrálódtak a Habsburg-ellenes mozgalmak – a tanulmányból az is kiderül, hogy Eperjes és az eperjesi kollégium nemcsak általában az evan-gélikusoknak, hanem a függetlenségi küzdelmeknek is egyik fő szellemi központja volt.
Adalékok és adatok az ágostai hitvallású líceumok diákságáról (1790-1850)
Authors: Durovics Alex
Published: January 2025

Az 1780-as és 1790-es évek politikai változásai új helyzetet teremtettek az evangélikusok számára. Az új körülmények közepette egyes iskolák folytatták a korábban megkezdett felsőbb fokú oktatást célzó fejlődésüket, míg mások új lendületet nyerve újonnan építették ki a felsőfokú stúdiumokat. Az evangélikus líceumok a 19. század első felében jelentős változásokon mentek keresztül, s sokszor egyedi választ adtak a különböző kihívásokra. A líceumi hallgatók adatain keresztül ezt a változatos képet láthatjuk igen részletesen. Hallgatói létszámra és von-záskörzetre nézve e hierarchia élén Pozsony líceuma állt, amelyet az eperjesi és késmárki in-tézmény követett. Köztes csoportba tartozott Sopron és Lőcse iskolája, Selmecbánya és Szarvas pedig a fejlődő tanintézetek körébe sorolható. Nagyságuk vagy éppen földrajzi elhelyezkedésük szerint ezek az iskolák különböző arányban ugyan, de nem egyszer hiánypótló módon jelen-tettek képzési helyszínt más felekezetek diákjainak is.
Repressed Teachers of Ukraine: Yakiv Feofanovych Chepiha (Zelenkevych) (1875-1938)
Authors: Berezivska Larysa
Published: January 2025

The article reveals the significant milestones in the life and work of the Ukrainian teacher, psychologist, and public person, author of more than 150 works (articles, manuals, textbooks) Yakiv Feofanovych Chepiha (1875-1938). It is argued that the educator, relying on Western European and American researchers, developed the ideas of the national school, native language education, national, labor, and free education, and pedology. He became a victim of Stalin’s totalitarian system as his views did not match communist ideology. Nowadays, in independent Ukraine, his name has been brought back from oblivion, and his creative heritage has gained relevance.

Conceptos básicos de probabilidad en un aula compartida por estudiantes sordos y oyentes usando una secuencia didáctica
Authors: Vidal García Lilibeth , Bohórquez Castañeda Martha Patricia
Published: January 2025

Se presenta el diseño y la implementación de una secuencia didáctica (SD) para desarrollar conceptos de probabilidad en estudiantes de 7º grado de un aula compartida entre niños sordos y oyentes, que cuenta con el apoyo de un intérprete de lengua de señas colombiana (LSC). Para su diseño, se privilegia el concepto de aprendizaje visual, el uso de material concreto, las representaciones gráficas, la experimentación y las actividades lúdicas, con el fin de superar las barreras de comunicación y motivar a los estudiantes a su propia construcción de conceptos básicos de probabilidad, tales como experimento aleatorio, espacio muestral, diagrama de árbol y asignación de probabilidades, en congruencia con los estándares básicos de competencias del Ministerio de Educación Nacional (MEN). Se parte de una prueba diagnóstica que muestra que ningún estudiante tiene nociones de probabilidad. Posteriormente, se diseña y aplica la SD, y se comparan tanto la ejecución como los resultados obtenidos por ambos grupos en cada una de las actividades. Los niños sordos asimilaron los conceptos de la misma forma que los oyentes, necesitando una mínima intervención del intérprete de LSC para la comprensión y el desarrollo de las actividades.
Development of porous concrete pavements with waste materials for flood control
Authors: Savic Aleksandar , Skondric Marina , Govedarica Ognjen , Terzic Anja , Rajakovic-Ognjanovic Vladana
Published: January 2025

An inventive design for porous concrete pavement slabs was established in
this study. Following the "circularity" agenda and zero waste principles,
the design of the permeable concrete mix was founded on several
waste/byproduct raw materials, including solidified wastewater treatment
sludge (SWS), modified solidified wastewater treatment sludge (MWS), and
waste from the desulfurization process (WFDP). Porous concrete was made
using cement, waste resources, admixtures, and natural and/or artificial
aggregates as component materials. Bulk density, water absorption,
compressive and flexural tensile strength, load-bearing capacity, resistance
to frost and salt, and abrasion resistance were assessed. Changes in
durability and mechanical qualities were tracked as the amount of waste
material increased. This study provides a deeper understanding of the
properties and possible uses of environmentally modified (green) porous
concrete pavement slabs, or pavers, to lower the danger of flooding in urban
settings. This concrete is considered environmentally friendly material for
sustainable construction because of its porous structure, which
significantly assists in regulating stormwater runoff, ensuring
infiltration, and reducing the number of pollutants before they reach the
groundwater. It has been demonstrated that a specific percentage of recycled
materials may be incorporated into porous concrete without compromising the
long-term viability or usefulness of permeable concrete, therefore complying
with the Zero Waste Agenda and Circular Economy principles.
Asset Securitizations and Stock Price Crash Risk: Evidence from Nonfinancial Firms
Authors: Jia Yifan , Kim Jeong-Bon , Mao Ying , Wang Ke , Wang Zheng
Published: January 2025

SYNOPSIS

This study examines the relation between asset-backed securitizations and future stock price crash risk in nonfinancial firms. We argue that the gain-on-sale accounting treatment for off-balance-sheet securitizations facilitates managers’ withholding of bad earnings news, leading to higher crash risk. Using a propensity score-matched sample of U.S. nonfinancial firms, we find that firms engaging in off-balance-sheet securitizations are associated with higher crash risk, especially for firms with gain on sales from securitizations. In 2010, the Financial Accounting Standards Board implemented SFAS 166/167 to tighten the criteria for securitization transactions to receive off-balance-sheet treatment. However, our difference-in-differences analysis shows no significant effect of SFAS 166/167 on reducing securitizing firms’ crash risk. Further analyses reveal that firms engaging in off-balance-sheet securitization before SFAS 166/167 conduct more real activity-based earnings management after SFAS 166/167. This evidence suggests that firms could continue to hide bad news through alternative channels as substitutes.

Exploring (In)Equity in the Internal Revenue Code: Discussions of Race in the Tax Classroom
Authors: Krieg Kimberly S. , Marino Amanda R. , Morris Landi
Published: January 2025

In this learning strategy (LS) we provide materials on how to discuss race as a source of inequity in the Internal Revenue Code (IRC). We provide online discussion questions, practice problems, classroom talking points, and guidance for student presentations to illustrate inequities between Black and white taxpayers. The assignments can be delivered in entirety or piecemeal. Our material is inspired by Dr. Dorothy Brown’s The Whiteness of Wealth: How the Tax System Impoverishes Black Americans—And How We Can Fix It, which identifies how the IRC contributes to the racial wealth gap. This LS supplements an individual taxation course with real-world application of the IRC. The accompanying Teaching Notes provide (1) additional commentary on in-class discussions, (2) example instructor slides, and (3) solutions to practice problems. Pre- and post-evidence of efficacy suggest that students who were uncomfortable discussing race before engaging with this content feel more comfortable doing so after.

Do Audit Firms’ Financial Statements Provide Information about Audit Quality?
Authors: He Shaohua , Lisic Ling Lei , Tan Liang , Wang K. Philip
Published: January 2025

Whether audit firms should disclose financial statements is controversial among investors, practitioners, and regulators. The debate centers on whether audit firms’ financial statements provide information about audit quality. Using hand-collected data from U.K. audit firms’ financial statements, we construct four measures that capture audit firms’ resource investments (i.e., human capital, workplace environment, technologies) and risk exposures (i.e., litigation provisions). We find that increases in audit firms’ staff costs, investments in tangible assets and IT software, and reductions in litigation provisions are associated with improved audit quality. The information in audit firms’ financial statements is not contained in their transparency reports or regulatory inspection reports. Additional tests show that increases in audit firms’ staff costs and tangible assets, as well as reductions in litigation provisions, are associated with improved audit efficiency.

Do Managers Pursue Their Budget Goals Using Revenues or Expenses?
Authors: Jackson Scott B. , Salzsieder Leigh , Schaefer Tammie J.
Published: January 2025

Evidence reveals that managers exercise discretion over budget estimates, but little is known about whether revenues or expenses are more susceptible to budget discretion. Drawing upon regulatory focus theory, we predict a pattern of budget discretion that has not previously been identified. To test our theory, we conduct a series of experiments where managers face a goal to either minimize the performance metric to avoid missing the target (minimal budget goal) or maximize the performance metric to achieve a desired outcome (maximal budget goal). When managers face a minimal budget goal, they are more likely to make self-interested budget estimates for uncertain expenses than monetarily equivalent uncertain revenues. Conversely, when managers face a maximal budget goal, they are more likely to make self-interested budget estimates for uncertain revenues than monetarily equivalent uncertain expenses. Thus, managers prefer acts of inclusion over acts of exclusion when pursuing their budget goals.

Nutrition and Types of Food: Effects on Pediatric Oral Health
Authors: Kadam Sandhya Jitendra , Guttikonda Krishna Veni , Guttikonda Bharat Ram Chowdry
Published: January 2025

Diet and nutrition have a two-way relationship with oral health. Sugar and acid in the foods can contribute to tooth decay and gum disease. On the other hand, nutrient-dense foods with vitamins and minerals strengthen gums and teeth and prevent dental problems. Obese children are more likely to experience dental problems like tooth decay, dental caries, gum, periodontal disease, and malocclusion due to a higher likelihood of consuming sugary foods and drinks, which are major contributing factors to poor oral health. Obesity and dental issues have common risk factors, which are related to poor eating habits, no physical activities, and overall sedentary lifestyle measures. Undernutrition can negatively affect dental health. When the body does not get enough nutrients, it prioritizes other functions over oral health, making the mouth more susceptible to infections and damage. As all other organs in the body need balanced nutrition for optimum growth, development, and function, ideal oral health depends on a nutrient-dense diet. This article provides an overview of the importance of healthy nutritional food for optimum functioning of oral health. It draws the attention of dentists and pediatricians to educate patients about nutrient-dense diet options.

Stained Glass Windows of the Church of Christ the King in Gliwice. Iconography and Restoration
Authors: KOMAR Beata
Published: January 2025

In Silesia at the turn of the 19th and 20th centuries and the interwar period, the most important in the production of glass, and thus stained glass, were German factories, among which the Josephinehütte in Szklarska Poręba, known not only in Europe, was the leader. In the Church of Christ the King in Gliwice, you can see stained glass windows by two German studios: Franz Mayer, Hofkunstanstalt & Glasmalerei from Munich and August and Jan Wagner from Berlin-Trepetow, also known as Puhl & Wagner, Gottfried Heinersdorff. The aim of the article is to present the stained glass windows of both studios and to fill the research gap regarding their activities in Gliwice. The article was created on the basis of an archival query in the parish archives, literature analyses, in situ research, interviews in the stained glass workshop and extremely valuable correspondence with an employee of Franz Mayer’s company. As a result of the conducted analyses, the icono-graphic material of all stained glass windows was obtained, the process of their renovation was familiarized and their current condition was assessed.
Nonlinearity of Conductor Behavior in the Context of Loads on Transmission Towers
Authors: WANDZIK Grzegorz , KOWALCZYK Grzegorz
Published: January 2025

The article presents the issue of determining the effects of conductors on the supporting structures of power lines using two different methods of applying partial safety factors (PSF). An assessment of the nonlinearity and disproportionality in the relationship between the conductor load and the tension force was carried out. The discussion identifies the source of differences in the approaches and assesses the impact of two primary factors: the curvature of the relationship between load and tension force, and the initial prestressing of the cable, which results in the displacement of the graph relative to the origin of the coordinate system. The investigation utilizes measures of nonlinearity to facilitate its assessment. A sensitivity analysis was performed to examine the difference between applying PSFs to actions and their effects. A series of numerical calculations, considering various spans, initial tensions, and load values, demonstrated the scale of the reduction in the design values of forces when safety factors are applied more naturally to the actions, not to their effects.
Investigation of the Thermal Degradation Behavior of Coal/Biomass Blends for Kinetics Analysis with Sequential Method Implication
Authors: SHOAIB Hafiz Muhammad , QURESHI Tayyab , KHAN Ihtisham , MAHMOOD Hamayoun , IQBAL Tanveer
Published: January 2025

Pakistan currently has a problem in the energy supply and demand. There is a large gap between supply and demand for electricity. The depletion of fossil fuels and environmental pollution factors also exist. These factors convert the intention to implement co-firing of coal and biomass. Being agricultural land and producing a significant amount of agricultural waste and have a little valuable use of this waste. Keeping in mind for effective use of this agro-waste the pyrolysis behavior of Pakistani local coal (LC), rice husk (RH), and their blends 75LC/25RH wt.%, 50LC/50RH wt.%, 25LC/75RH wt.% were studied using a thermogravimetric analyzer in a nitrogen environment with 10K/min heating rate. A sequential method approach is used to calculate kinetics parameters quickly and accurately. With the assumption of first-order reaction, calculation is performed. The research findings revealed that the addition of rice husk to the blends led to an increase in the activation energy for devolatilization, rising from 22.9 kJ/mol to 45.2 kJ/mol. However, the activation energy for char degradation decreased from 60.4 kJ/mol (100%LC) to 14.2 kJ/mol (100%RH) as the proportion of rice husk in the blends increased. Moreover, the rate of mass degradation also increased with higher amounts of rice husk in the blends. These results suggest that the decrease in char degradation activation energy allows for a reduction in operational temperature, thereby facilitating a reliable co-pyrolysis process. Such a process holds the potential to design a low-cost and effective gasification process, aiding in overcoming the energy challenges.
Improvement Plan for the Pre-Analytical Process of the SEMEDICLAB Laboratory Period 2022
Authors: Delgado Hillary Raquel Garcia , Bermúdez Maria Gabriela García , Murillo Alvaro José Giler , Martinez José David Vintimilla , Jara Carlos Alejandro Vera
Published: January 2025

Objective: SEMEDIC is a clinical laboratory that performs tests in the areas of hematology, biochemistry, urinalysis, immunology, coprology, and immunochemistry. This work aims to implement a continuous improvement plan for the pre-analytical process of the SEMEDICLAB laboratory in 2022.
 
Theoretical Framework: The research focuses on pre-analytical errors in clinical laboratories and their impact on the quality of results. It is based on the premise that, despite technological advances and automation, the pre-analytical phase remains a weak link in the clinical analysis process.
 
Method: The present study adopts an observational and descriptive methodology, as it allows for the visualization of the environment in which the research is carried out. It should be noted that no population or sample was considered; it was based on the identification, definition, and standardization of sub-processes of the SEMEDICLAB company process. Clause 5.4 of the ISO 15189:2012 checklist was used to identify the gap between the sub-processes currently completed.
 
Results and Discussion: The causes of the problem in the pre-analytical phase of the workers in the SEMEDICLAB laboratory were described, which were caused by non-compliance or omission of the ISO 15189: 2012 standard, related to clauses 5.4.2. "Information for patients and users," 5.4.4.2. "Instructions for pre-analytical activities," and 5.4.6 "Sample reception," where irregularities were observed.
 
Implications of the research: Research on pre-analytical errors has a direct impact on the quality of patient care, the efficiency of clinical laboratories, and the sustainability of health systems. By identifying the causes of these errors and developing strategies to prevent them, it contributes to improving patient safety and the reliability of laboratory results.

Objective: To determine the prevalence of malnutrition in patients with CKD not requiring dialysis treatment at the Hospital Naval de Guayaquil (HOSNAG) during the period January 2017 to December 2020.
 
Theoretical Framework: The research focuses on the prevalence and factors associated with malnutrition in patients with chronic kidney disease (CKD) who do not yet require dialysis. It is based on the premise that malnutrition is a common problem in patients with CKD, despite recommendations for low-protein diets. The research aims to explore whether the VGS, a subjective nutritional assessment tool, is useful to identify these malnourished patients and whether BMI can be a predictor of malnutrition in this population.
 
Methods: Observational, descriptive, cross-sectional, retrospective, prevalence-type study. Malnutrition was considered as two definitions: a BMI <20; a GSV B/C.
 
Results and Discussion: 205 cases were recovered, with a median age of 64 years, being 95 (46.3%) female. There were 12/205 (5.9%) cases which presented a BMI <20, equivalent to malnutrition. Subjective global assessment A, B and C was estimated in 95 (46.3%), 87 (42.4%) and 23 (11.2%), respectively. The prevalence of malnutrition in CKD patients not requiring dialysis treatment at HOSNAG between January/2017 to December/2020 was 5.9% (95% CI 3.3 - 10%) estimated using a BMI <20, and 53.6% (95% CI 46.8 - 60%) using a B/C VGS. BMI is not a useful marker in the prediction of malnutrition in patients with CKD not requiring dialysis treatment, according to the VGS.
 
Research implications: By more accurately identifying malnourished patients and the factors associated with this condition, more effective nutritional strategies can be implemented to improve their quality of life and survival. In addition, the results of this study can serve as a basis for the development of public policies and health education programs that promote better nutritional care for these patients.
 
Originality/value: This research presents a remarkable originality by focusing on a segment of the chronic kidney disease (CKD) population that has been less explored in previous studies: those patients who do not yet require dialysis.

Objective: This research aimed to analyze the importance of prevention and early diagnosis of Sexually Transmitted Infections (STIs) for women's health.
 
Methodology: To achieve this objective, a bibliographic research methodology was adopted, with a survey and analysis of articles, studies and data from scientific platforms such as SciELO, Scopus and Google Scholar, in addition to Brazilian repositories.
 
Results: The research revealed that, despite advances in public health policies, lack of information, social stigma and unequal access to health services are still significant barriers to the prevention and early diagnosis of STIs. It was also found that early diagnosis has a direct impact on reducing complications associated with STIs, such as infertility and cervical cancer, in addition to contributing to the reduction of disease transmission.
 
Conclusion: In conclusion, we highlight the need for more effective public policies, the intensification of sexual education and the reduction of stigma related to STIs to ensure that women have access to adequate health care and the prevention of these diseases.

Introdução: A expansão ortodôntica não cirúrgica em pacientes em crescimento é uma abordagem de tratamento eficaz e não invasiva dos problemas esqueléticos transversais da maxila. Por vezes, a atresia transversal maxilar pode ser mais evidente na região anterior da maxila. A correção num caso de atresia da pré-maxila pode beneficiar de uma terapêutica que incremente uma maior expansão anterior. Descrição do Caso Clínico: Paciente do sexo feminino, de 11 anos, com retenção do dente 53 e falta de espaço para a erupção dos dentes 13 e 23. Apresentava uma relação esquelética de classe I, classe I molar e atresia maxilar mais marcada na zona da pré-maxila. A nível facial, verificou-se encurtamento do lábio superior, desvio do mento para a direita e terço facial inferior aumentado. Discussão e Conclusões: Este relato de caso apresenta uma nova abordagem de expansão maxilar para tratar uma discrepância transversa maxilar com maior efeito na pré-maxila. Esta abordagem utiliza uma modificação do disjuntor Hyrax, tendo sido colocado um expansor rápido da maxila (RME) do tipo ´Fan”. Este disjuntor apresenta uma dobradiça na parte posteriordo aparelho com a finalidade de restringir a expansão excessiva na região intermolar. O protocolo de tratamento consistiu numa expansão maxilar durante a fase inicial do tratamento e terapia ortodôntica ativa. Um disjuntor Hyrax com parafuso “Fan” foi instalado, ativado durante 3 semanas, duas vezes por dia; após a expansão desejada ser alcançada, a terapia ortodôntica ativa foi iniciada com aparelho fixo bimaxilar. A duração do tratamento foi de 28 meses. O RME do tipo “Fan” causou apenas uma expansão mínima da largura intermolar quando comparado ao que se verificaria se um Hyrax fosse utilizado e a expansão anterior necessária de forma a permitir o desenvolvimento da desejada forma da arcada.

Objetivos: O objetivo deste trabalho consistiu em determinar se a existência de osteoporose (processo fisiológico em que ocorre perda de massa óssea) ou a sua terapia (com bifosfonatos - BP) são fatores de risco para a osseointegração e sobrevivência a longo prazo de implantes dentários. Métodos: Nesta revisão sistemática foram avaliados a taxa de falha de implante e perda óssea marginal em pacientes osteoporóticos, através da análise de variados artigos publicados entre 1990 e a atualidade. A pesquisa foi feita nas bases de dados PubMed, SciELO e LILACS, utilizando as seguintes palavras-chave: ´Osteoporose”, “Osseointegração”, “Implante Dentário”, “Bifosfonatos”. Os artigos foram selecionados de acordo com critérios de inclusão e exclusão e conforme a sua relevância. Dos 201 artigos obtidos, 53 respeitavam os critérios de inclusão. Após leitura completa, foram incluídos no final 16 artigos nesta revisão. Resultados: De uma forma geral, os artigos incluídos não demonstraram existir correlação significativa entre presença de osteoporose e falha do implante. Apenas em 2 dos 12 artigos foi reportada uma maior taxa de falha dos implantes em indivíduos com osteoporose. Em relação à terapêutica, apenas 1 dos 4 artigos estudados afirma existir associação entre terapêutica oral com BP e ocorrência de osteonecrose na mandíbula. A maioria dos artigos afirmam que é raro observar esta osteonecrose associada a terapêutica oral (a forma mais prescrita a pacientes osteoporóticos), ocorrendo mais frequentemente em pacientes sujeitos a terapia endovenosa, pela maior biodisponibilidade do fármaco. Conclusões: Com base nos resultados pode-se concluir que os pacientes com osteoporose podem com sucesso receber implantes dentários com taxa de sobrevivência semelhante aos pacientes saudáveis. A terapia oral com BP não é impedimento para a aplicação de implante, devendo, no entanto, o médico estar atento aos possíveis riscos, como a ocorrência de osteonecrose da mandíbula. Para lidar com este risco, o médico deve sempre informar o paciente, realizar uma excelente avaliação oral, aplicar protocolos cirúrgicos específicos e manter um controlo apertado da cicatrização.
