Authors: Kamble Aishwarya , Katge Farhin , Poojari Manohar , Bhanushali Parin , Patil Devendra , Nanavati Komal
Published: May 2023

Objectives: Dental caries is a common chronic disease amongst children and are typically evaluated using the DMFT/deft index (decayed, missing, and filled teeth for permanent dentition/decayed, extracted, and filled teeth for primary dentition). To address the limitations associated with these indices, alternative assessment tools such as the Caries Assessment Spectrum and Treatment (CAST) index and Ora test have been developed. These methods aim to estimate caries activity within the oral cavity more accurately. The objective of our study was to evaluate and correlate caries activity in 5-to-8-year-old children using Ora test and CAST index.
Materials and Methods: Thirty schoolchildren between the ages of 5 and 8 years were selected and allocated into two groups (n=15) with DMFT/deft scores of <5 (group A) and >5 (group B). Two separate blinded examiners administered the assessments by first determining CAST scoring, which was followed by Ora test. Statistical analysis was performed using Pearson correlation test and significance was set at P≤0.05.
Results: The mean time for color change of Ora test, was 118.53±23.28 minutes in group A and 53.33±15.07 minutes in group B. CAST severity scores were 3.67±2.08 and 15.7±9.70 for groups A and B, respectively. Time taken for color change in Ora test and CAST scores showed a significant negative linear relationship (P=0.039).
Conclusion: Based on the negative correlation between CAST scores and Ora test, it may be postulated that microbial activity is directly related to caries activity in 5-to-8-year-old children.

Published: May 2023

T and B lymphocytes development and function are highly dependent on Recombination Activating Genes (RAG) 1 and 2. RAG mutations result in different degree of T and B cell impaired function, broad clinical manifestations, and immunological manifestations. Pathogenic mutations cause severe combined immunodeficiency (SCID) phenotype, while hypomorphic mutations are responsible for leaky or partial SCID.
Here, we described a 4-year-old girl who had a persistent diarrhea, recurrent infection and vomiting. Although physicians were suspicious about autoimmune enteropathy, her molecular report showed a homozygous and novel RAG2 mutation in its core domain. The number of CD4 T cells and IgA level were lower than normal ranges. Lack of IgA brought about different GI complications. Our patient died finally because of the liver and gallbladder failure.
Case-Based Learning of Primary Immunodeficiency: A Pilot Gamification for Education
Authors: Hanaei Sara
Published: May 2023

Objectives: Proper knowledge transfer to medical students would be highly important in training future generation of physicians and scientists. the current pilot study was designed to determine a model of gamification would be efficient in education of primary immunodeficiency diseases (PIDs) in medical students. Results: 15 PIDs were selected among the most common PIDs, and were described as an infographic case-problem. The cases were distributed among the students via emails and social media. Generally, we received 125 answers (102 correct and 23 incorrect). For each correct answer, the student was rewarded with a grant. In case of an incorrect answer, the student was encouraged to continue efforts on providing the most accurate answer. The immediate feed-backs encouraged some students to more precisely seek for the correct answer. The pattern of received answers, could provide a clue for the trainer regarding which PIDs have been more commonly learnt and established in minds, and which ones may need more practice and explanation in classes. It is proposed that not only such methods would make the teaching-learning process more exciting, but also, they may lead to more permanent establishment of an educational concept in the students’ minds.

Authors: Zhao Liming , Liu Ying , Cao Ziting , Wang Jun , Huo Xin
Published: May 2023

Background: Proprotein convertase subtilisin / Kexin type 9 (PCSK9) inhibitors are efficacious lipid-lowering agents. This drug is related to improving the prognosis of patients with cardiovascular disease (CVD). The purpose of this meta-analysis was to systematically analyze the safety and efficacy of PCSK9 inhibitors in all published randomized controlled trials (RCTs).
Methods: As of October 25, 2021, we searched PubMed, EMBASE, MEDLINE, Cochrane Library and web of science.
Results: From 684 articles, we included 11 trials for meta-analysis, including 52511 participants (26938 in the PCSK9 inhibitor group and 25573 in the control group). In terms of effectiveness, PCSK9 inhibitors reduced the risk of major adverse cardiovascular events(MACE) (OR=0.89, 95% Cl: 0.83-0.95, P=0.0009), but did not significantly reduce the risk of cardiovascular death (OR=0.95, 95% Cl: 0.84-1.07, P=0.38) or all-cause death (OR=0.93, 95% Cl: 0.85-1.03, P=0.18); In terms of safety, PCSK9 did not increase the risk of treatment-emergent adverse events (TEAE)(OR=0.98, 95% Cl: 0.94-1.02, P=0.28).
Conclusion: PCSK9 inhibitors can significantly reduce the risk of MACE in patients with high cardiovascular risk, which is well tolerated, but the impact on the risk of death is unclear.

Published: May 2023

Background: We aimed to analyze the differences and changing trends of mortality of Injury and Poisoning (IP) between urban and rural areas and gender in China to find out the influencing factors and to propose improvement measures.
Methods: IP mortality, population, economy, medical and health information data came from the official website of the National Bureau of Statistics, and basic data on education level came from the Chinese Ministry of Education. Then the differences of the mortality of IP were compared between different areas and gender in China from 2009 to 2019, and the relationships between the mortality changes of IP and education level, GDP per capita, the numbers of practicing physicians, health institutions and urbanization rate were also explored by establishing a ridge regression model.
Results: The mortality of IP in rural areas was significantly higher than that of urban areas, and in male was higher than that of female (both P<0.001). Primary school graduates, GDP per capita, the number of practicing physicians, health institutions and urbanization rate had strong correlations (rmin=-0.622) with the mortality of IP. Ridge regression model showed that there was a quantitative relationship between primary school graduates, GDP per capita, the number of practising physicians, health institutions, urbanization rate and the mortality of IP in China.
Conclusion: As the difference of working nature, economic development imbalance, psychological and gender, the mortality of IP was significantly different, so the state should take more effective measures to develop the urban and rural areas balanced, and reduce the IP risk in some particular occupations.
Transformar la educación estética desde América Latina

La archivística, la diagramática y la cartográfica como ejes proyectuales de las prácticas artísticas contemporáneas
Authors: SOLÓRZANO AUGUSTO
Published: May 2023

La discusión actual sobre las prácticas artísticas contemporáneas gira en torno a los cambios y las innovaciones que viene enfrentando el campo artístico tras convertir la vida social en el eje de la investigación-creación. Dichos cambios han demandado por parte del artista la adopción de técnicas, métodos y herramientas más creativas para la investigación que permitan el abordaje de lo abstracto, lo simbólico y lo imperceptible como una unidad de sentido. En esta dirección se destaca el papel que la archivística, la diagramática y la cartográfica vienen desempeñando como campos que posibilitan la construcción de modelos conceptuales que 1) simplifican fenómenos complejos, 2) propician el reconocimiento de factores aparentemente irrelevantes, y 3) permiten, que más allá de la representación de la realidad, sea posible construir visiones distintas de la realidad. Esta amalgama de nuevas herramientas también posibilita evaluar situaciones concretas de la vida social a través de los recursos expresivos propios del arte y de la estética que superan la idea de sistematización y abra la puerta a géneros experimentales y a modelos híbridos concordantes con un mundo híbrido en el que los medios técnicos tradicionales ensayados en el arte comienzan a mostrar su insuficiencia.

Rituales cotidianos en performance y teatro posdramático. Problemas políticos y sociales
Authors: VILLALOBOS HERRERA ÁLVARO
Published: May 2023

La presente disertación enfoca de manera crítica los órdenes rituales cotidianos relacionados con problemas sociales y políticos en las propuestas de los artistas Rosemberg Sandoval de Colombia y la sociedad teatral Rimini Protokoll de Alemania, cuyos elementos conceptuales y formales surgen de campos disciplinares afines entre sí, pero a la vez tangencialmente diferentes: la performance que proviene de las artes visuales y el teatro performativo, denominado también teatro posdramático. En ambas disciplinas los temas que abarcan sus obras son sacados de la vida común y utilizados en el arte por medio de acciones conceptuales que los hacen visibles sobre todo en las sociedades urbanas. Estos artistas utilizan conceptos referentes a las realidades actuales presentadas de facto como arte, con ello evaden los prejuicios producidos por la estetización de lo político derivada de las corrientes teóricas influyentes en la sistematización de estas disciplinas.

Published: May 2023

Construir una experiencia sensible, requiere que el objeto percibido, en este caso la obra escénica, alcance un nivel de interacción entre artista y espectador que pueda producir una movilización interna del sujeto perceptor. Un momento que llegue a lo profundo del ser y que puede construir en éste una experiencia única. Entonces debe de haber un algo sensible arriba del escenario que promueva todo el fenómeno perceptivo y experiencial, y esto está a cargo del artista escénico, del o los cuerpos que construyen la acción escénica. La Eutonía, promueve una experiencia que afecta todas las dimensiones del ser a partir de una organización y sistematización de lo que la persona percibe. Esto permite el desarrollo del “Corpoescena” un estado integral del artista escénico que construye a partir del desarrollo de capacidades como la atención expandida, signos escénicos que parten de un cuerpo como unidad que dialoga con el espectador.

Znajomość zwilżalności skał jest bardzo istotna, gdyż zjawisko to wpływa na ważne właściwości złoża, takie jak: nasycenie resztkowe ropą, względna przepuszczalność i ciśnienie kapilarne. Zrozumienie zwilżalności złoża ma kluczowe znaczenie dla określenia najbardziej efektywnych sposobów wydobycia ropy naftowej. W artykule przedstawiono metodę jakościowej oceny rodzaju zwilżalności skał, w której zasadniczą rolę odgrywają pomiary magnetycznego rezonansu jądrowego. Wykorzystuje się tutaj zróżnicowanie czasów relaksacji podłużnej T1, uwarunkowane rozkładem płynów w skale. Wykonanie badań wymagało użycia jednorodnego materiału skalnego. Badania zostały przeprowadzone na dwóch seriach próbek pobranych z dwóch bloków piaskowca: A (piaskowiec szydłowiecki biały) i B (piaskowiec szydłowiecki czerwony). Obydwa piaskowce charakteryzują się dużą jednorodnością, co potwierdzono pomiarami gęstości właściwej, gęstości objętościowej, porowatości helowej oraz badaniami na porozymetrze rtęciowym. Wykonano również standardowe pomiary czasów relaksacji poprzecznej T2 oraz wyznaczono skład mineralny dla reprezentatywnej próbki z piaskowca A i piaskowca B. Piaskowce te cechuje różny typ zwilżalności, co potwierdzono pomiarami współczynnika zwilżalności n standardową metodą elektryczną. W badaniach zastosowano dwa rodzaje płynów złożowych: solankę o mineralizacji 50 g/l oraz ropę naftową. W przypadku badania oddziaływania piaskowców z ropą naftową użyto dwóch rodzajów ropy o różnej lepkości dynamicznej: 7,43 mPa · s i 1,12 mPa · s. Skały nasycone ropą były przechowywane przez kilka dni w temperaturze około 65°C celem doprowadzenia ich do stanu zwilżenia ropą. Pomiary czasu relaksacji podłużnej T1 wykonano zarówno dla obu serii próbek skał, jak też dla zastosowanych płynów złożowych. Skały badano w stanie pełnego nasycenia, w stanie resztkowego nasycenia oraz po nasiąkaniu (ang. imbibition). Wykonane badania wykazały, że dystrybucja czasów relaksacji podłużnej T1 dobrze obrazuje rozkłady wody i ropy w skałach i może być wykorzystana do jakościowego opisu rodzaju zwilżalności.

W artykule zaprezentowano wyniki analizy sejsmicznej i otworowej dla utworów jury górnej z rejonu usytuowanego na południe i południowy wschód od Tarnowa, której celem było określenie potencjału geotermalnego tego obszaru. Przeprowadzona analiza geologiczno-złożowa wykazała, że skały węglanowe górnej jury są dobrym kolektorem wód geotermalnych, a najbardziej perspektywiczne do uzyskania większych wydajności są strefy uskokowo-szczelinowe oraz strefy pogrążonego paleokrasu. Świadczą o tym opróbowania przeprowadzone w otworach wiertniczych w interwale skał górnojurajskich, które wykazały przypływy wód termalnych o wydajnościach do 30 m3/h i temperaturze rzędu 50–80°C. Duża część z tych opróbowań związana jest bądź to ze strefami spękań i uskoków, bądź też z przypowierzchniową strefą rozwoju paleokrasu. Wspomniane utwory górnej jury zalegają w obszarze badań na głębokości od 1600 m do ponad 3000 m p.p.m. W ich nadkładzie występują węglanowe utwory kredy górnej, klastyczne utwory miocenu (autochtonicznego i jednostki zgłobickiej) oraz utwory jednostek tektonicznych Karpat. Zakres przeprowadzonych badań pozwolił na rozpoznanie budowy geologicznej oraz warunków złożowych analizowanego rejonu. Było to podstawą do wytypowania obszaru perspektywicznego, zlokalizowanego we wschodniej części obszaru badań, w obrębie którego można spodziewać się wyższych temperatur oraz możliwości uzyskania większych wydajności wód termalnych, koniecznych do zasilania obiektów energetycznych, ciepłowniczych czy też rekreacyjnych. W rejonie tym na podstawie danych sejsmicznych wyinterpretowano obecność skomplikowanego systemu uskoków, w większości o przebiegu z NW na SE. Dla wytypowanego obszaru perspektywicznego przedstawiono szczegółową charakterystykę parametrów złożowych, istotnych w kontekście poszukiwania i eksploatacji wód geotermalnych.

Jednym z potencjalnych kierunków rozwoju energetyki w Polsce jest wykorzystanie dla celów geotermalnych jako źródła energii głęboko zlokalizowanych wód o wysokich temperaturach. Udostępnianie złóż geotermalnych wiąże się z wysokimi wymogami stawianymi stosowanym płuczkom wiertniczym. Wysoka temperatura i ciśnienie panujące na dnie otworu wiertniczego są główną przyczyną zmiany parametrów reologicznych, ekwiwalentnej gęstości cyrkulacyjnej i objętości płuczki wiertniczej. Dlatego niezmiernie istotne jest, aby płuczka wiertnicza miała odpowiednią charakterystykę przewodnictwa cieplnego. Szczególnie ważne jest to w przypadkach wiercenia otworów, gdzie występująca różnica między ciśnieniem porowym a ciśnieniem szczelinowania jest niewielka. Właściwości termofizyczne, takie jak przewodność cieplna i ciepło właściwe płuczki wiertniczej, wpływają na wymianę ciepła i odgrywają zasadniczą rolę w profilu temperaturowym cieczy wiertniczych cyrkulujących w otworze. Przewodność cieplna i właściwa pojemność cieplna są zależne od składu płuczki wiertniczej, gęstości, właściwości reologiczno-strukturalnych i zawartości fazy stałej. W artykule przedstawiono badania przewodności cieplnej wodnodyspersyjnych płuczek wiertniczych przeznaczonych do wierceń geotermalnych. Określono wpływ podstawowych składników płuczki oraz środków do regulowania jej parametrów na właściwości termofizyczne. Zaprezentowane zostały wyniki badań z zakresu prac eksperymentalnych zmierzających do wyboru i zastosowania środków chemicznych poprawiających przewodność cieplną płuczek wiertniczych. Na podstawie analizy otrzymanych wyników z badań laboratoryjnych opracowano skład płuczki wiertniczej do wiercenia otworów geotermalnych charakteryzującej się zwiększonymi wartościami przewodności cieplnej przy zachowaniu wysokiej odporności na działanie wysokiej temperatury i ciśnienia.

The article indicates that engineering design criteria do not provide measures to prevent failures; this is evidenced by the occurrence of many accidents. Fracture prevention criteria should be derived from the principles of fracture mechanics, what should be developed further. However, the current concepts of fracture mechanics, when properly applied, provide an opportunity to ensure the reliability of the structure or organise the supervision of expensive structures to ensure their safe operation. These methods of preventing damage can be divided into two large groups: 1) checking for the formation of cracks and 2) monitoring their development. Both methods are based on similar principles; it would be easier to explain them with examples. To ensure the safe operation of the pressure vessel used in the reactor, the maximum allowable initial crack size should be known. The size of this crack should not expand to a critical point during the entire operation of the reactor. Knowing how the process of crack propagation proceeds and how the structure behaves during failure, it is possible to calculate the critical size of the defect and, based on this, calculate the maximum allowable size of the crack at the beginning of operation. Proper inspection of the new vessel will eliminate the possibility of shells that are larger than the original size. Checking for the presence of cracks, and determining their rate of growth during operation, presents significant difficulties. Therefore, checks should be avoided during operation. If the fracture and crack growth calculations, as well as the initial checks, are carried out correctly, then checks made during operation are an optional extra. However, in practice, such checks should still be performed. For vessels used in reactors, remote observation of crack growth using ultrasonic waves is a particularly useful method. If a crack is found, measures must be taken to either repair or replace the partially destroyed element.

Foram coletadas 194 respostas por meio de questionário online e realizadas 23 entrevistas online. Os principais autores do referencial teórico foram Empoli (2019) e Zuboff (2021). Os estudantes utilizam o número de visualizações como critério de escolha de um vídeo, o que pode deixá-los expostos à desinformação. Eles costumam comparar o conteúdo com outras fontes para validar o conteúdo e relatam que esse aprendizado de verificação decorreu de suas experiências na universidade, na família e na internet. Assim, o uso confiável do YouTube para estudos depende de uma abordagem crítica dessa tecnologia pelos estudantes.
Natura człowieka w twórczości Dostojewskiego
Authors: Perkowska Iwona Magdalena
Published: May 2023

This article is a presentation of the problem of human nature in Dostoevsky's writings. Its author does not agree that the great Russian thinker would give his assent to any of the two opposing ideas: neither that man is good by nature nor that his fate from the moment of birth is tragic. Dostoevsky has proved that freedom constitutes the core of human being. When this freedom is used in a wrong way man becomes bad, and if it is used according to Jesus Christ teachings, he may attain righteousness due to His Grace. In such circumstances, there is no space for any predetermination. Man is free, if he wants to be free. He has got free will. He is always responsible for everything he has done.
Dostoevsky uses the term n a t u r e in two different meanings. The first one is essential and refers to the notion of freedom. Consequently, Dostoevsky claims, human nature is beyond full cognition. The second meaning of the term nature refers to the attributes of a particular nation. The differences between nations are further evidence of freedom, which manifests in an infinity of ways. Nature understood as such can be changed and comprehended. The change requires much effort over a long period of time but can by achieved. To capture the full picture of the problem of human nature in Dostoevsky's ultimately it works, both meanings of the above notion should be the taken into consideration.
La idea de lo negativo en el psicoanálisis
Authors: Escardó de la Fuente Adela
Published: May 2023

El trabajo comprende un abordaje inicial sobre el tema de lo negativo, sus definiciones y las aproximaciones de Winnicott, Bion y Green al respecto. La revisión permite apreciar una confluencia de significados entre estos autores, que consideran lo negativo como el reverso de lo manifiesto; es decir, lo latente, acentuando la falta, la ausencia que predomina en patologías severas y limítrofes. Lo negativo se evidencia en los ataques al pensamiento y a las relaciones, donde priman la desligadura y la descatectización. Los autores concuerdan en la relevancia de las pulsiones destructivas, que imprimen su sello característico en lo negativo.
Las cartas a Fliess : una vía diferente de acercamiento al psicoanálisis
Authors: Maldonado Pedreros Miguel Angel
Published: May 2023

El presente trabajo plantea un acercamiento a los inicios del pensamiento freudiano desde el análisis de la correspondencia entre Freud y Fliess. El autor propone que el análisis de las cartas a Fliess puede facilitar una comprensión más empática de Freud y del psicoanálisis como tal, ya que presenta a un Freud más humano, lo cual favorece la identificación con él. Se aprecia cómo confluye el autoanálisis de Freud con el desarrollo de la teoría psicoanalítica, que deviene en el descubrimiento de conceptos trascendentales, entre los que destacan la sexualidad infantil, la fantasía y el complejo de Edipo.
Los desórdenes alimentarios y "las nuevas enfermedades del alma" : ¿una coincidencia?
Authors: Zusman Tinman Lillyana
Published: May 2023

Los desórdenes alimentarios, que ingresan al siglo XXI convertidos en conductas sociales aprobadas por una cultura que recoge modelos del nuevo deber ser femenino, exigen una lectura interdisciplinaria y multicausal. Se propone considerarlos como desórdenes étnicos, en los que el cuerpo, más que una estructura somática, es una construcción social. Este síndrome se comprende como una de «las nuevas enfermedades del alma» (Kristeva 1993), que, como patologías de acción, favorecen una lectura intertextual de un mensaje que se inscribe en el cuerpo, se aprueba en la sociedad y se comprende solo desde el inconsciente.

Published: May 2023

In this manuscript, we investigate the dynamics behavior of a fractional-order Leslie-Gower model by considering fear effect in the prey and Allee effect in predators. Firstly, all possible equilibrium points are analyzed by identifying the conditions of their existence and local stability. Here, we find four equilibrium points, where two local stable points and two unstable points. Furthermore, we also investigate the stability changing caused by Hopf bifurcation when the order of derivative changes. Finally, we perform several simulations to support our analysis results.
Spatial Analysis of Dengue Disease in Jakarta Province
Authors: Sobari Muhamad , Jaya I Gede Nyoman Mindra , Ruchjana Budi Nurani
Published: May 2023

Dengue disease is a virus-borne illness spread by the bite of the female Aedes aegypti mosquito. Jakarta Province has a vulnerability to dengue disease due to high population density and percentage of urban slum households. This study applied a spatial autoregressive (SAR) model to identify the risk factors that affect the number of dengue disease cases in Jakarta Province. The spatial dependency was accounted for using the queen contiguity spatial weight matrix. The number of flood-prone points, the number of slum neighborhood associations, the population density, the number of hospitals and the number of public health centers per 1,000 population and spatial lag significantly impact the number of dengue disease cases in Jakarta Province. When dengue disease cases increase in one sub-district, the number of dengue disease cases in the sub-districts around it will increase as well because of the positive and significant spatial lag coefficient. Based on the direct impact, each addition of one percent of flood-prone points in one sub-district will increase the number of dengue disease cases in that sub-district by 3.86 cases

Determination of Term Life Insurance Premiums with Varying Interest Rates Following The CIR Model and Varying Benefits Value
Authors: Puspita Dian , Purnaba I Gusti Putu , Lesmana Donny Citra
Published: May 2023

Term life insurance is an insurance that provides protection for a certain period that has been agreed upon in the policy. The policy is an agreement that contains the participant's obligation to pay premiums contributions to the insurance company and the insurance company's obligation to pay benefits in the event of a risk to the insurance participant as agreed in the policy. Interest rates will influence the calculation of premium value and benefits in the long term. So we need a model of interest rates that will change by time. One of the models that can be used is the CIR model. This research purposes to simulate the CIR model that will be carried out to determine interest rates for calculating term life insurance premiums for five years, with premiums paid at the beginning of the 1/m interval or monthly premium payments and benefits paid at the end of the 1/m interval when the participant dies. The case that will be discussed is when the benefit various. The results of this study are the CIR model can be applied to calculate the term life insurance premiums for five years and the premium calculation results show that the amount of the premium increase every year with varying benefits.

This case study explores the 2018–22 implementation of a national community-based surveillance (CBS) programme in Sudan. The programme was designed to meet critical needs of the existing health surveillance system. It aimed to empower communities to detect and contain public health threats, improve relations between communities and their local health system, and involve villages in rural areas. Federal, state, and locality (district) staff attended CBS workshops before recruiting and training community volunteers. Over 8,000 volunteers across 11 states were recruited. The volunteers alerted staff to priority syndromes for communicable diseases as well as local events with public health implications (e.g., natural disasters, conflict-induced displacement, food insecurity). Lessons learnt can be used to increase understanding of large-scale CBS programmes and to identify opportunities to strengthen new and existing programmes.

A key driver of workplace cognitive competencies is metacognition which has been shown to impact performance among nurses, teachers and firefighters, however, it is scarcely studied among managerial employees. The research investigating this relationship is also scattered across multiple domains limiting its’ utility for researchers and practitioners. This paper, therefore, presents an integrative review of the existing empirical literature from the Web of Science and Scopus database to trace the linkages of metacognition, workplace cognitive competencies and performance at work. The identified linkages are then formulated into a conceptual framework clarifying how various workplace cognitive competencies and performance may be linked to metacognition. The findings indicate linkages between metacognition and various workplace cognitive competencies such as problem-solving, decision-making, innovation, creativity and knowledge acquisition. The present research also establishes the link of metacognition and cognitive competencies with learning, individual and firm performance. The review paves way for metacognition to be considered as a distinct construct in the workplace, identifies gaps and provides direction for future research.

The use of high-resolution ultrasound (HRUS) thyroid imaging has resulted in a significant revolution in the treatment of thyroid nodules. The enigma of thyroid nodules has been a blind spot for radiologists for a long period. Reporting a thyroid nodule as benign or malignant is quite difficult and many times not accurate. The American Collage of Radiology-Thyroid Imaging Reporting and Data System (ACR-TIRADS) 2017 classification has solved this problem to a large extent. However, the classification needed pathological confirmation for it to be highly accurate. We compared our HRUS-based TIRADS labeling of thyroid nodules with thyroid cytopathology using revised Bethesda classification system. Patients detected with thyroid nodules by HRUS were categorized using ACR-TIRADS and further were taken for fine needle aspiration cytology (FNAC) in our department. The pathological results were compared with the initial TIRADS category of the nodule and the effectiveness of the TIRADS classification in categorizing nodules into benign and malignant was assessed using various statistical variables. The initial USG and the FNAC were performed by a single radiologist with over 10 years of experience. A total of 201 patients underwent HRUS followed by FNAC after obtaining written consent in our department. The thyroid nodules labeled as true benign on ACR-TIRADS (TIRADS 2) were all true benign on Bethesda cytopathology (less than Bethesda III), confirming the high accuracy of HRUS. The diagnostic accuracy of HRUS in cases of ACR-TIRADS 3 nodules was approximately 90.6% with an error rate of 9.4%. Nodules labeled as ACR-TIRADS 4 and 5 had error rates of 47% and 10% in labeling nodules as malignant. The ultrasound-based ACR-TIRADS system can accurately predict the likelihood of specific nodules being benign. There is a strong concordance between Bethesda cytology and ACR-TIRADS classification, particularly for benign nodules. In resource-constrained system like ours, patients with TIRADS 2 and 3 nodules can be safely followed obviating the need for an invasive procedure like FNAC.

Atherosclerosis (AS) is a chronic progressive disease caused by various factors, and causes various cerebrovascular and cardiovascular diseases (CVDs). Reducing the plasma levels of low-density lipoprotein-cholesterol (LDL-C) is the primary goal in preventing and treating AS. Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) plays a crucial role in regulating LDL-C metabolism. Panax notoginseng has potent lipid-reducing effects and protects against CVDs, and its saponins induce vascular dilatation, inhibit thrombus formation, and are used in treating CVDs. However, the anti-AS effect of the secondary metabolite, 20(S) -protopanaxatriol (20(S)-PPT), remains unclear. In this study, the anti-AS effect and molecular mechanism of 20(S)-PPT were investigated in vivo and in vitro by western blotting, real time-polymerase chain reaction (RT-PCR), Enzyme-linked Immunosorbent Assay (ELISA), immunofluorescence staining, and other assays. The in vitro experiments revealed that 20(S)-PPT reduced the levels of PCSK9 in the supernatant of HepG2 cells, upregulated low density lipoprotein receptor (LDLR) protein levels, promoted LDL uptake by HepG2 cells, and reduced PCSK9 mRNA transcription by upregulating the levels of FoxO3 protein and mRNA and decreasing the levels of HNF1α protein and mRNA. The in vivo experiments revealed that 20(S)-PPT upregulated aortic αSMA expression, increased the stability of atherosclerotic plaques, and reduced aortic plaque formation induced by a high-cholesterol fed in ApoE-/- mice (HCF group). Additionally, 20(S)-PPT reduced the aortic expression of CD68, reduced inflammation in the aortic root, and alleviated the hepatic lesions in the HCF group. The study revealed that 20(S)-PPT inhibited LDLR degradation via PCSK9 to alleviate AS.

Multipactor is a common discharge phenomenon occurred in space microwave systems. The surface microstructure has been verified to be effective to mitigate multipactor. In this work, we design a square coaxial low-pass filter (SCLPF) with dielectric sheets loaded to check the multipactor dependence on the structure parameters of the loaded dielectric sheets, and further model groove structures on the sensitive area surface to lower the risk of multipactor. Simulation results indicate that the SCLPF loaded with alumina and PTFE exhibits good operational characteristics, and the multipactor threshold is significantly improved after introducing the surface grooves. Then we investigate the effects of three typical groove parameters, groove depth, groove number, and aspect ratio, on the multipactor threshold of the SCLPF device. The results show that the multipactor threshold raise at first as the groove number and groove depth increase, and then the threshold reaches a saturation status. For a deeper analysis of multipactor, we discuss how the grooves shelter the secondary electrons, and further mitigate the electron avalanche. Furthermore, the mechanisms of threshold saturation under the effect of groove parameters are analyzed in detail, and a contour map for the multipactor threshold of PTFE-loaded SCLPFs is given, which makes significant sense for predicting the multipactor threshold of the devices with its sensitive surface being grooved. The regularity of modulating the multipactor threshold by the groove structures obtained in this study is of engineering significance for suppressing multipactor in microwave devices in practical applications.

Background:

Historically, humeral shaft fractures have been successfully treated with nonoperative management and functional bracing; however, various surgical options are also available. In the present study, we compared the outcomes of nonoperative versus operative interventions for the treatment of extra-articular humeral shaft fractures.

Methods:

This study was a network meta-analysis of prospective randomized controlled trials (RCTs) in which functional bracing was compared with surgical techniques (including open reduction and internal fixation [ORIF], minimally invasive plate osteosynthesis [MIPO], and intramedullary nailing in both antegrade [aIMN] and retrograde [rIMN] directions) for the treatment of humeral shaft fractures. The outcomes that were assessed included time to union and the rates of nonunion, malunion, delayed union, secondary surgical intervention, iatrogenic radial nerve palsy, and infection. Mean differences and log odds ratios (ORs) were used to analyze continuous and categorical data, respectively.

Results:

Twenty-one RCTs evaluating the outcomes for 1,203 patients who had been treated with functional bracing (n = 190), ORIF (n = 479), MIPO (n = 177), aIMN (n = 312), or rIMN (n = 45) were included. Functional bracing yielded significantly higher odds of nonunion and significantly longer time to union than ORIF, MIPO, and aIMN (p < 0.05). Comparison of surgical fixation techniques demonstrated significantly faster time to union with MIPO than with ORIF (p = 0.043). Significantly higher odds of malunion were observed with functional bracing than with ORIF (p = 0.047). Significantly higher odds of delayed union were observed with aIMN than with ORIF (p = 0.036). Significantly higher odds of secondary surgical intervention were observed with functional bracing than with ORIF (p = 0.001), MIPO (p = 0.007), and aIMN (p = 0.004). However, ORIF was associated with significantly higher odds of iatrogenic radial nerve injury and superficial infection than both functional bracing and MIPO (p < 0.05).

Conclusions:

Compared with functional bracing, most operative interventions demonstrated lower rates of reoperation. MIPO demonstrated significantly faster time to union while limiting periosteal stripping, whereas ORIF was associated with significantly higher rates of radial nerve palsy. Nonoperative management with functional bracing demonstrated higher nonunion rates than most surgical techniques, often requiring conversion to surgical fixation.
