Mycobacterium tuberculosis é a principal bactéria patogênica causadora da doença sistêmica granulomatosa crônica, a tuberculose (TB). Embora a TB pulmonar seja a mais prevalente, ela também pode apresentar-se de forma extrapulmonar nas vias hematológica e linfática em casos em que a resposta imunológica está reduzida. Objetivo: Relatar um caso clínico de tuberculose ganglionar em paciente pediátrico. Material e métodos: Trata-se de uma abordagem descritiva e qualitativa, com observação direta das informações do paciente para o diagnóstico e devido tratamento. Relato de caso: Paciente feminino, 4 anos, deu entrada no Hospital da Restauração – Governador Paulo Guerra, Recife (PE), com história de aumento de volume sintomático ao toque em região submandibular direita relacionado a exodontia recente do dente 85. Ao exame físico não foram identificados focos de infecção intrabucal dignos de nota e a paciente foi internada para investigação clínica. Os exames de imagem mostraram uma área indicativa de trajeto fistuloso. Foram prescritos sete dias de antibiótico (ceftriaxona e metronidazol) sem sucesso, sendo necessário substituir para clindamicina. A paciente foi submetida a procedimento de exérese de lesão tecidual sob anestesia geral, e o material foi enviado para exame histopatológico com laudo compatível com processo granulomatoso tuberculoide. Solicitou-se teste para micobactérias, sendo positivo. Quatro meses após a remoção da lesão, a paciente encontra-se em acompanhamento clínico, sem sinal de recidiva. Discussão: As crianças e os indivíduos imunossuprimidos são mais susceptíveis a tuberculose extrapulmonar, sendo os linfonodos cervicais os sítios mais acometidos. Conclusão: Apesar da dificuldade de diagnóstico, em virtude da sintomatologia inespecífica, principalmente em crianças, são imprescindíveis o rápido diagnóstico e o manuseio terapêutico, resultando em melhores taxas de prognóstico favorável.

A nano-hidroxiapatita (nano-HAp) tem sido estudada como um material biomimético que promove a remineralização da superfície dentária e a obliteração dos túbulos dentinários, sendo considerada uma alternativa ao uso de flúor. Além dos benefícios à estrutura dentária, e ao contrário do flúor, a ingestão acidental de nano-HAp como componente dos cremes dentais não está associada a nenhum risco sistêmico relevante para a saúde. Objetivo: Avaliar in vitro o potencial da nano-HAp em remineralizar a estrutura dentária, comparando três diferentes formulações de cremes dentais: nano-hidroxiapatita sintética pura, nano-hidroxiapatita sintética com flúor e apenas flúor, por meio da microscopia eletrônica de varredura (MEV) e análise química (EDS). Material e métodos: Realizou-se um estudo experimental transversal com abordagem qualitativa. Amostras de dentes, terceiros molares, cortados em blocos, expondo superfície de esmalte e dentina, foram submetidos à desmineralização por intermédio de imersão em ácido fosfórico 37% por 30 segundos, seguida de lavagem em água corrente. Posteriormente, efetuaram-se escovações com os três cremes dentais e em um grupo controle, durante dez dias consecutivos. Ao fim do experimento foi feita uma análise qualitativa com microscopia eletrônica de varredura (MEV) e análise química (EDS). Resultados: No grupo controle não houve obliteração dos túbulos dentinários e alteração da morfologia da superfície dentinária. Nos cremes dentais com nano-hidroxiapatita 5% e nano-hidroxiapatita com flúor, observaram-se deposição mineral na superfície da dentina e obliteração dos túbulos dentinários, contudo há uma deposição mais uniforme no creme dental com nano[1]hidroxiapatita 5%. No creme dental com flúor, notou-se deposição mineral, entretanto mais sutil e apenas dentro de alguns túbulos dentinários, sem alterar a morfologia da dentina. Conclusão: A nano-hidroxiapatita promoveu uma deposição mineral na superfície da dentina e no interior dos túbulos dentinários, demonstrando resultados promissores na remineralização da estrutura dentária.

Published: June 2023

A odontologia minimamente invasiva tem chamado a atenção de endodontistas por causar o mínimo de alteração nos tecidos dentais duros, preservando ao máximo a forma e função do dente tratado endodonticamente. Entretanto a literatura ainda está divergente em relação à perda de resistência quanto ao tipo de acesso endodôntico, tradicional ou minimamente invasivo. Objetivo: Avaliar a resistência a fratura entre grupos de dentes pré-molares superiores submetidos a acessos endodônticos tradicionais e minimamente invasivos, por intermédio do método de compressão contínua. Material e métodos: Foram usados 24 pré-molares superiores extraídos, íntegros e hígidos, mantidos congelados em água destilada até o momento do estudo. Os dentes foram posicionados e incluídos em um tubo de PVC, preenchido com resina acrílica autopolimerizável. Dividiram-se as amostras em grupos experimentais (n=12) conforme tipo de acesso endodôntico: tradicional ou minimamente invasivo. Após os acessos realizou-se o teste de resistência mecânica em uma máquina de testes universal (EMIC DL 500), em que os dentes foram submetidos a uma força de compressão contínua até a fratura. Resultados: O teste t de Student não detectou diferenças estatisticamente significativas entre os grupos experimentais (p=0.115), demonstrando que o grupo em que os dentes foram submetidos a acessos endodônticos tradicionais apresentou valores de resistência a compressão semelhantes ao grupo submetido a acessos endodônticos minimamente invasivos. Conclusão: Com base nos resultados conclui-se que não houve diferença na resistência a compressão entre acessos endodônticos tradicionais e minimamente invasivos.

Published Patents
Authors: Raghav Shraddha Singh , Kumar Bhavna , Sethiya Neeraj Kumar , Lal Diwya Kumar
Published: June 2023

Background:

One of the most challenging effects of diabetes is diabetic foot ulceration
(DFU). DFU may occur in up to one-third of individuals with diabetes mellitus (D.M.) at some
point in their lives. The major cause of morbidity in D.M. patients is DFU. The length of treatment
is difficult, and DFU recurrence is common.

Objective:

The most crucial element for the treatment and prevention of DFUs require a multidisciplinary
approach. Patients who are at risk should be identified, depending on the type of risk,
prophylactic actions etc. It is imperative to identify at-risk patients and take preventative measures
accordingly.

Method:

The at-risk diabetes-related foot ulcer was identified based on the risk category classification,
while the foot ulcers were evaluated using Wagner's classification system.

Results:

Literature reported that patients with lower limb vascular insufficiency, loss of vibratory
sensation, or protective sensation loss have an increased risk of developing foot ulcers. Proper categorization
and therapeutic measures will be implemented after the DFU has been formed. The appropriate
assessment and management of general health status should include glycemic control, the
diagnosis and treatment of vascular disease, standard care for wounds, diagnosis, and infection
treatments.

Conclusion:

The review reflects the updated awareness of the treatment and management of DFU
based on the current and past literature and patent analysis.

of Diuresis
Authors: Manvi  , Khan Mohammad Irfan , Badruddeen  , Akhtar Juber , Ahmad Mohammad , Siddiqui Zeba , Fatima Gayyur
Published: June 2023

Background:

Medicinal plants have been found beneficial in the control and therapy of many ailments as they contain bioactive compounds, and many of them are used as precursors in the biosynthesis of natural medicines. Diuretics are used as a primary treatment in patients with edema associated with liver cirrhosis and kidney diseases, hyperkalemia, hypertension, heart fail-ure, or renal failure. Furthermore, they are also used to increase the excretion of sodium and re-duce blood volume. Due to various adverse events associated with synthetic diuretics, there is a need to investigate alternate plant-based bioactive components that have effective diuretic activity with minimal side effects.

Objective:

This review compiled the reported bioactive compounds from different plant sources along with their mechanisms of diuretic activity.

Methods:

Different sources were used to collect information regarding herbal plants with thera-peutic value as diuretics. These included published peer-reviewed journal articles, scholarly arti-cles from StatPearls, and search engines like Google Scholar, PubMed, Scopus, Springer, Sci-enceDirect, Wiley, etc.

Results:

In this review, it was found that flavonoids like rutin, acacetin, naringenin, etc. showed significant diuretic activity in experimental models by various mechanisms, but mostly by block-ing the sodium-potassium-chloride co-transporter, while some bioactive compounds showed diu-retic actions via other mechanisms as well.

Conclusion:

Research on clinical trials of these isolated bioactive compounds needs to be further conducted. Thus, this review provides an understanding of the potential diuretic bioactive com-pounds of plants for further research and pharmaceutical applications.
Endless Journey of Adenosine Signaling in Cardioprotective Mechanism of
Conditioning Techniques: Clinical Evidence
Authors: Kumar Kuldeep , Singh Nirmal , Yadav Harlokesh Narayan , Maslov Leonid , Jaggi Amteshwar Singh
Published: June 2023

Myocardial ischemic injury is a primary cause of death among various cardiovascular
disorders. The condition occurs due to an interrupted supply of blood and vital nutrients (necessary
for normal cellular activities and viability) to the myocardium, eventually leading to damage. Restoration
of blood supply to ischemic tissue is noted to cause even more lethal reperfusion injury.
Various strategies, including some conditioning techniques, like preconditioning and postconditioning,
have been developed to check the detrimental effects of reperfusion injury. Many endogenous
substances have been proposed to act as initiators, mediators, and end effectors of these conditioning
techniques. Substances, like adenosine, bradykinin, acetylcholine, angiotensin, norepinephrine,
opioids, etc., have been reported to mediate cardioprotective activity. Among these
agents, adenosine has been widely studied and suggested to have the most pronounced cardioprotective
effects. The current review article highlights the role of adenosine signaling in the cardioprotective
mechanism of conditioning techniques. The article also provides an insight into various
clinical studies that substantiate the applicability of adenosine as a cardioprotective agent in myocardial
reperfusion injury.
3D Synthetic Brain MRI with Compressed Sensing: A Promising Way Forward for Daily Neuroimaging
Authors: Baek Hye Jin , Heo Young Jin , Cho Eun , Lee Kwangho
Published: June 2023

Background:

Synthetic MRI can provide multiple contrast-weighted brain images with high resolution from a single scan via a 3D sequence using an interleaved Look-Locker acquisition sequence with a T2 preparation pulse (3D-QALAS).

Objective:

This study aimed to assess the diagnostic image quality of 3D synthetic MRI using compressed sensing (CS) in clinical practice.

Methods:

We retrospectively reviewed the imaging data of 47 patients who underwent brain MRI, including 3D synthetic MRI using CS in a single session, between December 2020 and February 2021. Two neuroradiologists independently evaluated the overall image quality, anatomic demarcation, and artifacts for synthetic 3D T1-weighted, T2-weighted, FLAIR, phase-sensitive inversion recovery (PSIR), and double inversion recovery images, using a 5-point Likert scale. The interobserver agreement between the two readers was assessed using percent agreement and weighted κ statistics.

Results:

The overall image quality of 3D synthetic T1WI and PSIR was good to excellent, with easy or excellent anatomic demarcation and mild or no visible artifact. However, other 3D synthetic MRI-derived images showed insufficient image quality and anatomic demarcation with marked CSF pulsation artifacts. In particular, 3D synthetic FLAIR showed high-signal artifacts on the brain surface.

Conclusion:

3D synthetic MRI, at its current status, cannot completely replace conventional brain MRI in daily clinical practice. However, 3D synthetic MRI can achieve scan-time reduction using CS and parallel imaging and may be useful for motion-prone or pediatric patients requiring 3D images where time-efficiency is important.

AN EXPERIENCE OF IMPLEMENTING SOFTWARE DEVELOPMENT MANAGEMENT SYSTEM BY COMBINING CMMI WITH AGILE IN SMALL AND MEDIUM-SIZED ORGANIZATION
Authors:   Kim Il Sung University, DPR of Korea
Published: June 2023

Nowadays, the research on improvements of software development processes has been developing extensively in software organizations. Currently these researches are focusing on how to combine CMMI with Agile. In addition, most of the software development organizations all over the world are small or medium, not large. Such small and medium-sized organizations play a great role in the software industry. However, there is lack of case studies that small and medium-sized organizations implement CMMI process areas to establish their development management systems, especially practical and helpful case studies that such organizations may apply to combine with Agile for improving their management systems. Our goal is to share our experience in successful improvements of development process under the industrial environment from an empirical point of view. And these results cannot be generalized, but they point out that under some circumstances in small and medium-sized organizations, a combination strategy of CMMI and Agile can be a possible option for software professionals. In this paper we present our experience of implementing a DMS (Development Management System), in which CMMI is combined with Agile, for a small and medium-sized software development aiming at CMMI level 3. Moreover, we give the result that our organization applied this DMS.
Successful Online Choir for People Living with Dementia: A Qualitative Case Study
Authors: MacDonald Rebecca , Zumbansen Anna
Published: June 2023

Group singing as a social musical activity can be used to improve the quality of life, well-being, and overall health of people with dementia and caregivers. Online choirs have gained awareness since the COVID-19 pandemic; however, singing in an online choir is an unsatisfying experience for most choir members in the general population. In order to report on the feasibility of creating an online choir for people with dementia, we studied a successful case of such a choir. This choir began and continued online for over a year, maintaining a group of about ten people. The objectives were to understand the participants' experience and explore factors contributing to its success. We surveyed 12 members using closed and open-ended questions (5 choristers with dementia, 5 caregivers, the choir director, and a volunteer). The thematic analysis of the responses revealed that (1) an online choir is better than no choir for participants with dementia, (2) participants sought and found in the online choir an accessible way to socialize and enjoy singing, and (3) obstacles to participate in an online choir (mostly technology-related) are not the same as those to participate in an in-person choir (mostly travel related). The success of this online choir may in part be attributed to the fact that it first started online (the members did not compare the experience to previous in-person rehearsals and had more flexible expectations); most participants with dementia had mild cognitive symptoms and had extensive previous choral singing experience.

Psychoanalysis of the Protagonist in “Perks Of Being A Wallflower” by Stephen Chbosky and “Girl, Interrupted” by Susanna Kaysen
Authors: Singh Janhvi
Published: June 2023

Psychoanalysis is a powerful tool that helps authors explore the psychological depths of their characters. In this paper, I will argue that psychoanalysis of the protagonists in these novels is essential to understanding their behaviour, thoughts, and actions through the theory given by Sigmund Freud. In particular, in the case of The Perks of Being a Wallflower, the psychoanalytic hypothesis encourages the pursuer to comprehend the entirety of his unusual practices and considerations. In addition, it is utilised to uncover recollections to uncover past occasions that cause present-day mental disturbances.
