ABSTRACT

Este artigo traz reflexões com base no acervo virtual da Folha de S.Paulo, identificando representações do usuário de substâncias psicoativas veiculadas pelo jornal no período da Ditadura Militar brasileira, anos notáveis por aspectos políticos, culturais, jurídico-legais e médicos diretamente associados às drogas. Nesse contexto, foram selecionadas notícias sobre o assunto veiculadas pela Folha, dada a sua ascensão nacional, na década de 1960, pela fusão da Folha da Manhã e da Folha da Noite, e como empresa de mídia aliada do governo ditatorial. Para isso, foram feitas consultas ao repositório virtual do jornal usando adjetivos que referenciam quem utiliza substâncias psicoativas: "drogado", "toxicômano", "usuário de drogas", "usuário de entorpecentes", "viciado em drogas" e "dependente químico"). Surgiram duas categorias: saúde e crime. Delas derivam as representações do usuário de drogas. Ao longo do texto, reflete-se sobre os processos de sua visibilidade e estigmatização e a maneira como isso impacta atualmente. Reflete-se ainda sobre o caráter democrático do acesso ao repositório digital do jornal, bem como sobre os atuais movimentos nostálgicos do ufanismo existente no período ditatorial e seus impactos nas políticas de drogas.


This article reflects on the virtual archive of Folha de S.Paulo, identifying representations of psychoactive substance users published by that newspaper during the Brazilian Military Dictatorship, years notable for the political, cultural, legal and medical aspects directly associated with drugs. In this context, news on the subject published by Folha was selected, given its national rise in the 1960s through the merger of Folha da Manhã and Folha da Noite, and as a media company allied with the dictatorial government. To do this, the newspaper's virtual repository was searched using adjectives that refer to those who use psychoactive substances: "drugged", "drug addict", "drug user", "illegal narcotics user", "hooked on drugs" and "chemical dependent"). Two categories emerged: health and crime. The representations of drug users derive from these. Throughout this text, we reflect on the processes of their visibility and stigmatisation and the way in which this has an impact today. We also reflect on the democratic nature of access to the newspaper's digital repository, as well as the current nostalgic movements for chauvinism that existed during the dictatorial period and their impact on drug policies.


Este artículo aporta reflexiones basadas en el acervo virtual de la Folha de S.Paulo, identificando las re-presentaciones de los usuarios de sustancias psicoactivas publicadas por el periódico durante la Dictadura Militar brasileña, años destacados por los aspectos políticos, culturales, jurídicos y médicos directamente asociados a las drogas. En este contexto, fueron seleccionadas noticias sobre el tema publicadas por la Folha, dada su proeminencia nacional en la década de 1960 a través de la fusión de Folha da Manhã y Folha da Noite, y como medio de comunicación aliado del gobierno dictatorial. Para hacerlo, se realizó una búsqueda en el repositorio virtual del periódico utilizando adjetivos que hacen referencia a quien consume sustancias psicoactivas: "yonqui", "toxicómano", "usuario de drogas", "usuario de estupefacientes", "dro-gadicto" y "químicamente dependiente"). Surgieron dos categorías: salud y crimen. De ellas se derivan las representaciones de los usuarios de drogas. A lo largo del texto, reflexionamos sobre los procesos de su visibilidad y estigmatización y la forma como esto repercute en la actualidad. También reflexionamos sobre el carácter democrático del acceso al repositorio digital del periódico, así como sobre los actuales movi-mientos nostálgicos del ufanismo que existió durante la dictadura y su impacto en las políticas de drogas.

ABSTRACT

Bovine mastitis is a disease wi th far - reaching consequences for the dairy industry. Staphylococcus aureus is a pathogen that is especially resistant to antibiotics. The objective of this study was to evaluate the antimicrobial activity of the essential oils Lippia citriodora (Lam.), Thy mus vulgaris (L), and a mixture of the essential oils Lippia citriodora and Thymus vulgaris (50/50 v/v), against isolates of oxacillin - resistant Staphylococcus aureus (n=15) of positive cases of bovine mastitis. For the statistical analysis, the IBM SPSS s tatistical package was used. The mixture of essential oils ( Lippia citriodora and Thymus vulgaris (50/50 v/v)) obtained the most significant antimicrobial activity in relation to pure essential oils. It is therefore concluded that the mixture of these oils boosts their antimicrobial activity ( p <0.05). The minimum inhibitory and bactericidal concentration of this mixture for the total isolations was 12 µL/L and 25 µL/mL, respectively.


La mastitis bovina es una enfermedad de gran impacto para la industria lechera. El Staphylococcus aureus es uno de los principales patógenos, especialmente aquellos resistentes a los antibióticos. El objetivo de este estudio fue evaluar la actividad antimicrobiana de los aceites esenciales de Lippia citriodora (Lam.), Thymus vulgaris (L), y una mezcla de aceites esenciales de Lippia citriodora y Thymus vulgaris (50/50 v/v), frente a aislamientos clínicos de Staph ylococcus aureus oxacilino - resistentes (n=15) de mastitis bovina. Se utilizó p rograma estadístico IBM SPSS y se concluyó la diferencia significativa a un p <0.05. La mezcla de aceites esenciales ( Lippia citriodora y Thymus vulgaris (50/50 v/v)), obtuvo la m ayor actividad antimicrobiana en relación a los aceites esenciales puros, se concluye que la mezcla de estos aceites potencia su actividad antimicrobiana ( p <0.019). La concentración mínima inhibitoria y bactericida de esta mezcla fue del 12 µL/mL y 25 µL/m L, respectivamente, y puede ser una alternativa terapéutica.

ABSTRACT

SUMMARY: Despite comprehensive studies and reports about the properties of dental pulp stem cells (DPSCs) in vitro, we still need to confirm whether these in vitro characteristics coincide with the nature of DPSCs in situ. The anatomical location of DPSCs populations in the dental pulp has yet to be investigated. Moreover, the mesenchymal DPSCs have been much more studied than the neural crest-derived DPSCs. In this study, well-recognized neural/neural crest stem cell markers NCAM1, Nestin, SNAIL/SLUG, SOX9, and S100 are being investigated by immunohistochemistry to localize the precise location of these populations of DPSCs within the human adult dental pulp.All previously mentioned markers were expressed in the dental pulp, and their intensity and location of expression were reported.


A pesar de estudios e informes exhaustivos sobre las propiedades de las células madre de la pulpa dental (DPSC) in vitro, todavía necesitamos confirmar si estas características in vitro coinciden con la naturaleza de las DPSC in situ. La ubicación anatómica de las poblaciones de DPSC en la pulpa dental aún no se ha investigado. Además, las DPSC mesenquimales han sido mucho más estudiadas que las DPSC derivadas de la cresta neural. En este estudio, se están investigando mediante inmunohisto química marcadores de células madre de la cresta neural/ neural NCAM1, Nestin, SNAIL/SLUG, SOX9 y S100 para localizar la ubicación precisa de estas poblaciones de DPSC dentro de la pulpa dental humana adulta. Todos los marcadores mencionados anteriormente se expresaron en la pulpa dental y se informó su intensidad y ubicación de expresión.

ABSTRACT

Abstract Introduction: Echinoderms, an integral component of marine ecosystems worldwide, have captivated scientific interest for centuries. Despite this longstanding attention, comprehending key facets such as trophic relationships, diet composition, and host-microbiota relationships still represents a challenge using traditional techniques. Recent years, however, have witnessed a transformative shift, thanks to the emergence of advanced molecular techniques, offering new approaches to strengthen ecological studies in echinoderms. Objective: Explore how recent advancements in molecular tools have impacted ecological research on echinoderms. Specifically, we aim to investigate the potential of these tools to shed light on trophic interactions, diet composition, and the characterization of gut microbial communities in these organisms. Methods: Available literature was used to clarify how novel molecular techniques can improve ecological studies. The focus is diet, trophic relationships, and gut microbiota. Results: Traditionally, studies of stomach contents using compound microscopy have provided an idea of ingested material; nevertheless, sometimes a simple magnified visualization of dietary content does not allow exhaustive identification of the entire food spectrum, as it is limited due to the rapid digestion and maceration of food items within the echinoderm's digestive tract. The use of DNA-metabarcoding, targeting specific DNA regions, such as the mitochondrial COI gene, has allowed us to enhance the accuracy and precision of diet characterization by enabling the identification of prey items down to the species or even genetic variant level, providing valuable insights into specific dietary preferences. Another approach is the use of stable isotopes, particularly carbon and nitrogen, which provide a powerful tool to trace the origin and flow of nutrients through food webs. By analyzing the isotopic signatures in muscular tissues and food items, we can discern the sources of their primary food items and gain insights into their trophic position within the ecosystem. Lastly, a third new technique used to elucidate the characterization of the prokaryotic community is 16S rRNA sequencing. This method allows us to explore the composition and dynamics of the digestive tract microbial communities. Conclusions: This is a promising era for ecological research on echinoderms, where advances of molecular tools have enabled an unprecedented level of detail, resolving longstanding challenges in comprehending their trophic interactions, diet composition, and host-microbiota relationships, and opening new avenues of investigation in ecological studies.


Resumen Introducción: Los equinodermos, un componente integral de los ecosistemas marinos en todo el mundo, han captado el interés científico durante siglos. A pesar de esta prolongada atención, el comprender facetas clave como las relaciones tróficas, la composición de la dieta y las relaciones huésped-microbiota todavía representa un desafío utilizando técnicas tradicionales. Sin embargo, los últimos años han sido testigos de un cambio transformador, gracias a la aparición de técnicas moleculares avanzadas, que ofrecen nuevos enfoques para fortalecer los estudios ecológicos en equinodermos. Objetivo: Explorar cómo los avances recientes en herramientas moleculares han impactado la investigación ecológica sobre equinodermos. Específicamente, nuestro objetivo es investigar el potencial de estas herramientas para arrojar luz sobre las interacciones tróficas, la composición de la dieta y la caracterización de las comunidades microbianas intestinales en estos organismos. Métodos: Se utilizó la literatura disponible para aclarar cómo las nuevas técnicas moleculares pueden mejorar los estudios ecológicos. La atención se centra en la dieta, las relaciones tróficas y la microbiota intestinal. Resultados: Tradicionalmente, los estudios del contenido estomacal mediante microscopía compuesta han proporcionado una idea del material ingerido; Sin embargo, a veces una simple visualización ampliada del contenido dietético no permite una identificación exhaustiva de todo el espectro alimentario, ya que está limitado debido a la rápida digestión y maceración de los alimentos dentro del tracto digestivo del equinodermo. El uso de metabarcoding de ADN, dirigidos a regiones específicas del ADN, como el gen COI mitocondrial, nos ha permitido mejorar la exactitud y precisión de la caracterización de la dieta al permitir la identificación de presas hasta el nivel de especie o incluso de variante genética, lo que proporciona valiosos resultados sobre preferencias dietéticas específicas. Otro enfoque es el uso de isótopos estables, en particular carbono y nitrógeno, que proporcionan una poderosa herramienta para rastrear el origen y el flujo de nutrientes a través de las redes alimentarias. Al analizar las firmas isotópicas en los tejidos musculares y los alimentos, podemos discernir las fuentes de sus alimentos primarios y obtener información sobre su posición trófica dentro del ecosistema. Por último, una tercera técnica nueva utilizada para dilucidar la caracterización de la comunidad procariótica es la secuenciación del ARNr 16S. Este método nos permite explorar la composición y dinámica de las comunidades microbianas del tracto digestivo. Conclusiones: Esta es una era prometedora para la investigación ecológica sobre equinodermos, donde los avances de las herramientas moleculares han permitido un nivel de detalle sin precedentes, resolviendo desafíos de larga data en la comprensión de sus interacciones tróficas, composición de la dieta y relaciones huésped-microbiota, y abriendo nuevas vías de investigación. en estudios ecológicos.

ABSTRACT

Abstract Interaction between severe acute respiratory coronavirus 2 (SARS-CoV-2) and IIEB remains under investigation. Objective: to compare IIEB incidence before and during COVID-19 pandemic, and assess incidence of coinfection with COVID-19 and case fatality. A cross-sectional study was performed on data from a centralized microbiology laboratory serving a network of healthcare centers comprising 713 pediatric and adult inpatient beds, expanded by 20% during the pandemic. Three periods were evaluated: (1) pre-pandemic: March 1, 2019-February 29, 2020; (2) pandemic year 1: March 1, 2020-February 28, 2021; (3) pandemic year 2: March 1, 2021-July 31, 2021. Descriptive statistical analysis was performed. 56502 samples (96% blood cultures) from 27224 patients were analyzed. Of these, 54 samples (from 54 patients) were positive for encapsulated bacteria. IIEB incidence was: 167.4, 32.6, and 50.4 per 100000 samples for periods 1, 2, and 3, respectively. Twelve IIEB episodes occurred during the pandemic period: 10 Streptococcus pneumoniae, and 2 Haemophilus influenzae, of which 7 were SARS-CoV-2/S. pneumoniae coinfections, with an incidence of 5.68 per 10000 COVID-19-related hospitalizations (0.056%). IIEB case fatality was 31%, 29%, and 60% for each period, respectively, 3/7 patients with coinfection died (43%). Case fatality for invasive pneumococcal disease (IPD) in patients without COVID-19, was 32.5%. Significant reduction in IIEB incidence was observed during the pandemic, coinciding with implementation of containment measures. The incidence of SARS-CoV-2/S. pneumoniae coinfection was low, with higher case fatality than IPD patients without COVID-19.


Resumen La interacción entre SARS-CoV-2 e infecciones invasivas por bacterias capsuladas (IIBC) continúa bajo estudio. Objetivos: comparar la incidencia de IIBC antes y durante la pandemia por COVID-19, evaluar la incidencia de coinfección con COVID-19 y la letalidad. Estudio transversal de registros de un laboratorio centralizado de Microbiología, que asiste a una red de centros asistenciales con 713 camas de internación para adultos y pediátricos, expandida 20% durante la pandemia. Tres periodos evaluados: 1) Pre-pandemia: 1-Marzo-2019 al 29-Febrero-2020; 2) Primer año de Pandemia: 1-Marzo-2020 al 28-Febrero-2021; 3) Pandemia 2021: 1-Marzo-2021 al 31-Julio-2021. Análisis estadístico descriptivo: Se analizaron 56.502 muestras (96% hemocultivos) correspondientes a 27.224 pacientes. De estas, 54 muestras (de 54 pacientes) fueron positivas para bacterias capsuladas. La incidencia de IIBC fue 167,4, 32,6 y 50,4 por cada 100.000 muestras para los periodos 1, 2 y 3, respectivamente. Doce IIBC ocurrieron durante la pandemia: 10 Streptococcus pneumoniae y dos Haemophilus influenzae, siete de ellos corresponden a coinfección SARS-CoV-2/S. pneumoniae, con una incidencia de 5,68 por cada 10.000 internaciones por COVID 19 (0,056%). La letalidad de las IIBC fue de 31, 29 y 60% para los tres periodos, respectivamente, 3/7 coinfectados fallecieron (43%). La letalidad por enfermedad neumocócica invasiva (ENI), sin COVID fue de 32,5%. Se evidenció una reducción significativa de la incidencia de IIBC luego del comienzo de la pandemia, coincidente con la implementación de las medidas sanitarias de contención de la pandemia. La incidencia de coinfección de SARS-CoV-2/S. pneumoniae fue baja y presentó mayor letalidad que las ENI sin COVID-19.

ABSTRACT

El objetivo del artículo es reportar el desempeño clínico en el control y disminución de la placa bacteriana en pacientes adolescentes mediante un gel y barniz con partículas S-PRG. Se realizaron tratamientos con materiales bioactivos con tecnología GIOMER en 2 pacientes. En el primer caso se realizó una profilaxis con Pro Care Gel (S-PRG) en un paciente de 15 años con problemas neuromotores para eliminar la placa y posteriormente, se aplicó un barniz con partículas de S-PRG para prevenir la formación de biofilm. En el segundo caso, un adolescente de 15 años normoreactivo con inflamación gingival recibió el tratamiento profilaxis con PRG Pro Care Gel.Se observó una disminución de placa bacteriana tras la profilaxis con el gel Pro Care y la aplicación del barniz en el primer caso. Además, existió una baja incidencia de biofilm incluso después de 11 meses de la aplicación del barniz. En el segundo caso, a las 2 horas de aplicación, se observó una disminución total de la placa. Clínicamente se observó el bueno desempeño clínico de los materiales con partículas de S-PRG, como lo demuestra la literatura científica en cuanto a la reducción de la formación de placa bacteriana en las estructuras dentarias, la desinflamación gingival, proporciona bienestar a los pacientes y restaura la salud bucal de forma menos invasiva.


The objective of the article is to report the clinical performance in the control and reduction of bacterial plaque in adolescent patients using a gel and varnish with S-PRG particles. Treatments with bioactive materials with GIOMER technology were performed in two patients. In the first case, prophylaxis was performed with Pro Care Gel (S-PRG) in a 15-year-old patient with neuromotor problems to eliminate plaque and subsequently, a varnish with S-PRG particles was applied to prevent biofilm formation. In the second case, a normal 15-year-old adolescent with gingival inflammation received prophylaxis treatment with PRG Pro Care Gel. A decrease in bacterial plaque was observed after prophylaxis with the Pro Care gel and the application of the varnish in the first case. Furthermore, there was a low incidence of biofilm even after 11 months of varnish application. In the second case, after 2 hours of application, a total decrease in plaque was observed. The good clinical performance of materials with S-PRG particles was clinically perceived, as demonstrated by the scientific literature in terms of reducing the formation of bacterial plaque in dental structures, gingival disinflammation, providing well-being to patients and restoring oral health in a less invasive way.

ABSTRACT

@#The phenomenon of depression has been a major concern recently, both nationally and globally. Depression is a disorder that involves changes in thoughts, emotions, feelings, and behaviours that make a person’s daily life difficult, and if left untreated, can adversely affect individuals and society. Depression among adolescents certainly deserves attention as this group is considered as an asset that will drive the country in the future. In terms of methodology, PubMed, Science direct, and Google Scholar search engines were used which focused on psychological theories related to adolescent depression. In addition, the search also focuses on Cognitive Approach or more precisely, about Cognitive Behaviour Theory (CBT). Over the past few decades, Cognitive Behaviour Theory (CBT) has been proven to be the most dominant theory in psychological studies including depression in adolescents. As a result, it is found that, under the CBT group, Learned Helplessness Theory and Beck’s Cognitive Behaviour Theory were the two most widely discussed on the concept of depression to date. Therefore, this article will discuss the background and the concept of these theories in describing depression. However, Beck’s CBT has been selected as the most appropriate theory in discussing depression in adolescents because this theory is able to explain this issue further and in detail, in addition to having an extensive amount of research showing the effectiveness of Beck’s CBT in helping adolescents with depression compared to Learned Helplessness Theory.

ABSTRACT

Objective@#To evaluate the bidirectional association between periodontitis and Sjögren's syndrome using the Mendelian randomization (MR) method.@*Methods@#Genome-wide association study (GWAS) data of periodontitis (N = 45 563) and Sjögren's syndrome (N = 214 435) were selected to meet the requirements of the same ethnicity and different regions. Inverse variance-weighted (IVW), MR-Egger, and weighted median (WM) tests were used to evaluate the causal effect. Cochran's Q statistics, MR-Egger intercept, MR-PRESSO and leave-one-out analysis were used as sensitivity analyses to assess the stability and reliability of the results.@*Results@#After screening, the GWAS data of Sjögren's syndrome were based on the Finnish region, and the periodontitis GWAS data were based on the UK region, both of which originated from European ancestry. Using IVW (OR = 1.017, 95% CI = 0.956-1.082), MR-Egger (OR = 0.985, 95% CI= 0.956-1.082), and WM (OR =1.021, 95% CI = 0.948-1.099), no causal effect of Sjögren's syndrome on periodontitis was found using any of the three methods. Conversely, no causal effect of periodontitis on Sjögren's syndrome was found (IVW, OR = 1.024, 95% CI = 0.852-1.230; MR-Egger, OR = 0.978, 95% CI = 0.789-1.212; WM, OR = 1.024, 95% CI = 0.846-1.260). The sensitivity analyses indicated that the results were stable and reliable. Cochran's Q test and MR-PRESSO revealed that there was no significant heterogeneity among the instrumental variables, which included single nucleotide polymorphisms (SNPs). The intercept of MR-Egger regression indicated no pleiotropy in the included SNPs. No individual SNP was found that significantly affected the results using the leave-one-out method.@*Conclusion@#This study does not support a bidirectional causal effect between periodontitis and Sjögren's syndrome.

ABSTRACT

ObjectiveTo explore the possible mechanism of the Yiqi Jiedu formula (YQ) in treating ischemic stroke (IS) from the perspective of the microbial-gut-brain axis (MGBA). MethodRats were randomly divided into five groups, with six in each group, including sham surgery group, model group, and low, medium, and high dose YQ groups (1, 5, and 25 mg·kg-1). Except for the sham surgery group, all other groups were established with a middle cerebral artery occlusion (MCAO) model using the thread occlusion method. The success of modeling was determined through neurobehavioral scoring, and the protective effect of YQ on IS was evaluated. Then, the changes in gut microbiota before and after MCAO modeling and YQ administration were compared using 16S rDNA sequencing technology, and the possible biological pathways related to the effect of this formula were analyzed. The expression of inflammatory factors such as interleukin-6 (IL-6), interleukin-17A (IL-17A), and interleukin-10 (IL-10) in serum was detected by enzyme-linked immunosorbent assay (ELISA). Western blot was used to detect the expression of tight junction proteins ZO-1 and Occludin in brain and intestinal tissue, and hematoxylin-eosin staining (HE) was used to observe pathological changes in the cerebral cortex and colon, so as to validate the possible mechanism of action. ResultYQ significantly improved the neurobehavioral score of MCAO rats (P<0.01) and played a good regulatory role in intestinal microbial disorders caused by enriched pathogens and opportunistic pathogens during the acute phase. Among them, significantly changed microorganisms include Morgentia, Escherichia Shigella, Adlercreutzia, and Androbacter. Bioinformatics analysis found that these bacteria may be related to the regulation of inflammation in the brain. Compared with the blank group, the detection of inflammatory factors in the serum of IS model rats showed an increase in inflammatory factors IL-6 and IL-17A (P<0.01) and a decrease in the content of anti-inflammatory factor IL-10 (P<0.01). Compared with the model group, the content of inflammatory factors IL-6 and IL-17A in the serum of the treatment group decreased (P<0.05), and that of anti-inflammatory factor IL-10 increased (P<0.01). The expression results of barrier proteins ZO-1 and Occludin in brain and intestinal tissue showed that the expression levels of both decreased in IS model rats (P<0.05), while the expression levels of both increased in the treatment group (P<0.05). ConclusionAcute cerebral ischemia can lead to an imbalance of intestinal microbiota and damage to the intestinal barrier, and it can increase intestinal permeability. YQ can regulate intestinal microbiota imbalance caused by ischemia, inhibit systemic inflammatory response, and improve the disruption of the gut-blood brain barrier, preventing secondary cascade damage to brain tissue caused by inflammation. The MGBA may be an important mechanism against the IS.

ABSTRACT

@#Objective    To retrospectively analyze the surgical treatment of Stanford type A aortic dissection after coronary artery stenting, and to explore the surgical techniques and surgical indications. Methods    Clinical data of 1 246 consecutive patients who underwent operations on Stanford type A aortic dissection from April 2016 to July 2019 in Beijing Anzhen Hospital were retrospectively analyzed. Patients with Stanford type A aortic dissection after coronary artery stenting were enrolled. Results    Finally 19 patients were collected, including 16 males and 3 females with an average age of 54±7 years ranging from 35 to 66 years. There were 11 patients in acute phase, 15 patients with AC (DeBakey Ⅰ) type and 4 patients with AS (DeBakey Ⅱ) type. In AC type, there were 10 patients receiving Sun's surgery and 5 patients partial arch replacement. Meanwhile, coronary artery bypass grafting was performed in 7 patients and mitral valve replacement in 1 patient. Stents were removed from the right coronary artery in 4 patients. In this group, 1 patient died of multiple organ failure in hospital after operation combined with malperfusion of viscera. Eighteen patients recovered after treatment and were discharged from hospital. The patients were followed up for 30 (18-56) months. One patient underwent aortic pseudoaneurysm resection, one thoracic endovascular aortic repair, one emergency percutaneous coronary intervention due to left main artery stent occlusion, and one underwent femoral artery bypass due to iliac artery occlusion. Conclusion    Iatrogenic aortic dissection has a high probability of coronary artery bypass grafting at the same time in patients with Stanford type A aortic dissection after coronary artery stenting. Complicated type A aortic dissection after percutaneous coronary intervention should be treated with surgery aggressively.

ABSTRACT

Objectives@#In the Philippines, there has been a lack of information on the concordance between classifications of Hansen’s disease or leprosy clinically, histopathologically, and with AFS results. The study ultimately aimed to determine the concordance between the clinical diagnosis, histopathological results, and AFS results of patients with leprosy seen at the Dr. Jose N. Rodriguez Memorial Hospital and Sanitarium (DJNRMHS). @*Methods@#This is a descriptive, retrospective, single-center study conducted at the DJNRMHS, a tertiary government hospital and one of the last remaining sanitaria in the country located in northern Metro Manila in the Philippines. The study reviewed and included all the patient records from the years 2017-2019 which included skin biopsy results and slit-skin smear with AFS. Leprosy patients were then classified based on the following classifications: World Health Organization (WHO) and Ridley-Jopling classifications; and the concordance of clinical diagnosis vs the histopathologic findings and clinical diagnosis vs AFS results were determined using kappa testing.

ABSTRACT

@#The functional health and stability of the oral and maxillofacial system is one of the basic goals of orthodontic treatment. Currently, it is believed that, in general, the condyle is located in the center of the joint fossa when the mandible is in an intercuspal position (ICP) in healthy normal people. At this time, the function of the temporomandibular joint (TMJ) is stable. Due to orthodontic tooth movement and subsequent occlusal changes, patients with malocclusion may experience related remodeling of the temporomandibular joint, especially changes in the position of the condyle. The position of the mandibular condyle is traditionally evaluated using a condylar position indicator. However, this method lacks consistency in obtaining condylar position changes. In recent years, in the clinical application of orthodontic treatment, cone beam computed tomography (CBCT) has become the first choice for examination. CBCT can accurately measure the interarticular space and determine changes in condylar position. This article reviews the CBCT assessment of condylar position and related research on condylar position changes in patients with malocclusion before and after orthodontic treatment. The literature review results indicate that there are differences in the condylar position of patients with different malocclusions, and the condylar position may also change before and after orthodontic treatment. With a lower radiation dose, CBCT has higher accuracy in evaluating the condylar position in patients with malocclusion who undergo orthodontic treatment, thus promoting further study of the mechanism of condylar position changes in patients with malocclusion in the future and providing more accurate and personalized guidance for patient treatment.

ABSTRACT

OBJECTIVE To reduce dispensing errors in pharmacy intravenous admixture service (PIVAS) of children’s hospitals. METHODS The risk of dispensing procedures in our PIVAS was identified by applying failure mode and effect analysis (FMEA) model. Potential failure modes that might lead to dispensing errors in each link were determined, and failure causes were analyzed. The severity, incidence and detection degree of potential failure modes were quantitatively scored, and their risk priority number (RPN) was calculated to screen failure modes that needed to be improved in priority; the corresponding improvement measures were developed by 6S management method from six aspects, namely, finishing (seiri), rectifying (seiton), sweeping (seiso), sanitation (seiketsu), literacy (shitsuke) and safety. The effect of intervention before and after rectification was evaluated. RESULTS Based on the RPN, 32 potential failure modes were selected, of which a total of 18 critical failure modes that needed to be improved in priority. After implementing corresponding measures according to 6S management method, the RPN of 18 critical failure modes decreased. The total RPN decreased from 497 to 142 with a decrease rate of 71.43%. The error rates of 15 critical failure modes were significantly lower than before implementation (P<0.05). CONCLUSIONS Applying FMEA model and 6S management method to the risk control of all aspects of PIVAS workflow can effectively reduce the risk of PIVAS dispensing errors and ensure the safety of children’s intravenous medication.

ABSTRACT

OBJECTIVE To explore the effects of alfentanil (ALF) on myocardial fibrosis in rats with acute myocardial infarction (AMI) by regulating sphingosine kinase 1 (SphK1)/sphingosine 1-phosphate (S1P) signaling pathway. METHODS Male SD rats were collected to construct AMI model by the ligation of anterior descending branch of left coronary artery. The successfully modeled rats were randomly divided into AMI model group (Model group), ALF low-dose group (ALF-L group, 0.25 mg/kg ALF), ALF high-dose group (ALF-H group, 0.5 mg/kg ALF), high dose of ALF+SphK1 activator group (ALF-H+K6PC-5 group, 0.5 mg/kg ALF+1 μg/g K6PC-5). At the same time, a sham operation group (Sham group) was set up to perform only chest opening/closing operations without ligating the anterior descending branch of left coronary artery, with 15 rats in each group. Rats in each drug group were intraperitoneally injected with the corresponding drug solution, once a day, for 4 consecutive weeks. Twelve hours after the last medication, cardiac function indicators [left ventricular systolic pressure (LVSP), left ventricular ejection fraction (LVEF), left ventricular systolic diameter (LVSD), left ventricular fractional shortening (LVFS)] of rats were detected in each group; the condition of myocardial infarction, pathological changes in myocardial tissue, and degree of fibrosis were observed; serum levels of brain natriuretic peptide (BNP) and cardiac troponin Ⅰ (cTnⅠ) in rats were detected. The protein expressions of collagen Ⅰ , collagen Ⅲ , matrix metalloproteinase-2 (MMP-2), SphK1 and S1P were alsodetected in the myocardial tissue of rats. RESULTS Compared with the Sham group, the arrangement of myocardial cells in the Model group was disordered, with a large number of inflammatory cells infiltrating. The levels of LVSP, LVFS and LVEF in the Model group were significantly reduced (P<0.05); LVSD level, myocardial infarction area, collagen volume fraction, serum levels of BNP and cTnⅠ, the protein expressions of collagen Ⅰ, collagen Ⅲ, MMP-2, SphK1 and S1P in myocardial tissue were significantly increased or enlarged (P<0.05). Compared with the Model group, the pathological changes and degree of fibrosis in the myocardial tissue of rats in each dose group of ALF were improved or relieved, while the quantitative indicators of rats in the ALF-H group were significantly improved and significantly better than those in ALF-L group (P<0.05). K6PC-5 could significantly reverse the improvement effect of high-dose ALF on the above quantitative indicators in rats (P<0.05). CONCLUSIONS ALF can reduce myocardial fibrosis and improve cardiac function in AMI rats, and the effect may be related to the inhibition of the SphK1/S1P signaling pathway.

ABSTRACT

Objective@#To evaluate the clinical efficacy of invisible orthodontic appliances without brackets for the distal movement of maxillary molars to improve the ability of orthodontists to predict treatment outcomes.@*Methods@#Web of Science, Cochrane Library, Embase, PubMed, Wanfang Database, CNKI Database, and VIP Database were searched for studies investigating the efficacy of invisible orthodontic appliances for distal movement of maxillary molars in adult patients and published from database inception to August 1, 2023. A total of three researchers screened the studies and evaluated their quality and conducted a meta-analysis of those that met quality standards.@*Results@#This study included 13 pre- and postcontrol trials with a total sample size of 281 patients. The meta-analysis revealed no significant differences in the sagittal or vertical parameters of the jawbone after treatment when compared with those before treatment (P>0.05). The displacement of the first molar was MD=-2.34, 95% CI (-2.83, -1.85); the displacement was MD=-0.95, 95% CI (-1.34, -0.56); and the inclination was MD=-2.51, 95% CI (-3.56, -1.46). There was a statistically significant difference in the change in sagittal, vertical, and axial tilt of the first molar before and after treatment. After treatment, the average adduction distance of the incisors was MD=-0.82, 95% CI (-1.54, -0.09), and the decrease in lip inclination was MD=-1.61, 95% CI (-2.86, -0.36); these values were significantly different from those before treatment (P<0.05).@*Conclusion@#Invisible orthodontic appliances can effectively move the upper molars in a distal direction and control the vertical position of the molars. When the molars move further away, there is some degree of compression and distal tilt movement, which is beneficial for patients with high angles. The sagittal movement of incisors is beneficial for improving the patient's profile.

ABSTRACT

Alzheimer's disease (AD) is a central nervous system degenerative disease that is prone to occur in the pre-senile period and senile period . It is characterized by behavioral impairment and progressive cognitive impairment, with an insidious onset and progressive aggravation. It not only has cognitive decline, but also is accompanied by other neurological and psychiatric symptoms. Memory loss is the core symptom of the disease. Diabetes mellitus (DM) is a disease characterized by hyperglycemia. In recent years, with the increasing incidence of the two diseases, more and more studies have reported the correlation between AD and DM. This article reviews the correlation between AD and DM from the aspects of correlation research, pathological mechanism and drug treatment through the review of relevant literature, with a view to providing guidance for clinical practice.

ABSTRACT

Objective To investigate the relieving effects of knockdown of long non-coding RNA(lncRNA)taurine up-regulated gene 1 (TUG1) on inhibiting nucleotide binding oligomerization domain like receptor protein 1 (NLRP1) inflammasome and the progression of Alzheimer’ s disease. Methods Wild-type (WT group, 10 mice) or amyloid precursor protein (APP) / presenilin-1 (PS1) transgenic mice (30 mice) with a genetic background of C57 / BL6 aged 9-10 weeks were used in this study. APP / PS1 transgenic mice were randomly divided into model group, model+lncRNA TUG1 short hairpin RNA (shRNA) group and model + shRNA non target (NT) group (n = 10) . Blood samples, cerebral cortex tissues, primary microglial cells and primary astrocytes were collected from mice 12 weeks of age on day 1 (3-month-old) and 32 weeks of age on day 1 (8-month-old), with 5 mice per group at each time point. Real-time PCR analysis was used to detect the expression levels of lncRNA TUG1 and macrophage migration inhibitory factor (MIF) mRNA in cerebral cortex tissues and primary microglial cells, and C1r and C1s mRNA levels in primary astrocytes of 3-month-old and 8-month-old mice in the above 4 groups, respectively. ELISA was used to determine the MIF in plasma samples of the above 4 groups of mice. Primary microglia and astrocytes from the cerebral cortex of 3-month-old and 8-month-old mice were co-cultured. CCK-8 method was used to determine the proliferation ability of the above cells. Western blotting was used to determine the expression levels of MIF, pro interleukin-1β (pro-IL-1β), apoptosis associated speck-like protein containing a caspase recrult domain(ASC), Caspase-1 (p20), Caspase-1 (full), NLRP1 and NLRP3 in cerebral cortex tissues of 3-month-old and 8-month-old mice. Immunofluorescent staining was used to determine amyloid beta(Aβ) in cerebral cortex of 8-month-old mice. Results At the age of 3-month-old and 8-month-old, compared with the WT group, the relative expression level of lncRNA TUG1 and MIF in cerebral cortex tissues and primary microglia of model group mice was significantly up-regulated, with primary microglial cells and astrocytes proliferation ability enhanced (P0. 05) . There was no significant difference between the model group and the model+shRNA NT group mice of all the above factors (P>0. 05) . Conclusion In APP / PS1 transgenic mice, up-regulation of lncRNA TUG1 and MIF are positively associated with the activation of NLRP1 inflammasome in mice cerebral cortex tissues and primary microglia. Knock-down of lncRNA TUG1 can ameliorate the progression of Alzheimer’ s disease.
