RÉSUMÉ

Background: Chat generative pre-trained transformer, an artificial intelligence chatbot can generate text-based content for information purpose. This study aims to find the accuracy and reliability of the chat GPT generated definitions for 30 common dental terms. Methods: A 15 current dental teaching staffs grading from Professors and Readers of various specialities participated in this study. They graded the chat GPT generated terms on a 5-point Likert scale (1- Strongly disagree, 2- Disagree, 3- Neutral, 4- Agree, 5- Strongly disagree). Scores were obtained and descriptive statistics was done and compared using Mann-Whitney U test. Results: Among 30 dental terms, 13 terms which were generated from the chat GPT model were found to be more appropriate when compared to text book definition. On comparison of reviewers’ perceptions for accuracy of definitions generated from chat GPT compared with text book definitions in which among the 30 dental terms, 9 terms were found to be statistically significant (p<0.05*). Conclusions: Chat GPT is a potential tool for answering knowledge based questions with equal vigor in the field of dentistry. Moreover, the accuracy of Chat GPT to solve questions in dentistry has a relational level of accuracy.

RÉSUMÉ

Abstract Sarcopenia is a pathology resulting from a progressive and severe loss of muscle mass, strength, and function in the course of aging, which has deleterious consequences on quality of life. Among the most widespread studies on the issue are those focused on the effect of different types of physical exercise on patients with sarcopenia. This randomized controlled study aimed to compare the effects of a whole-body vibration exercise (WBV) session on the inflammatory parameters of non-sarcopenic (NSG, n=22) and sarcopenic elderly (SG, n=22). NSG and SG participants were randomly divided into two protocols: intervention (squat with WBV) and control (squat without WBV). After a one-week washout period, participants switched protocols, so that everyone performed both protocols. Body composition was assessed by dual-energy radiological absorptiometry (DXA) and function through the six-minute walk test (6MWD) and Short Physical Performance Battery (SPPB). Plasma soluble tumor necrosis factor receptors (sTNFR) were determined by enzyme-linked immunosorbent assay (ELISA) and measured before and immediately after each protocol. After exercise with WBV, there was an increase in sTNFR2 levels in the NSG (P<0.01; d=-0.69 (-1.30; -0.08) and SG (P<0.01, d=-0.95 (-1.57; -0.32) groups. In conclusion, an acute session of WBV influenced sTNFr2 levels, with sarcopenic individuals showing a greater effect. This suggested that WBV had a more pronounced impact on sTNFr2 in those with loss of muscle strength and/or physical performance. Additionally, WBV is gaining recognition as an efficient strategy for those with persistent health issues.

RÉSUMÉ

Abstract Background The neuropeptide Y (NPY) is one of the most abundant neurotransmitters in the nervous system. NPY acts as a potent stimulator of angiogenesis, inflammation, and adipogenesis, through the NPY 2 receptor (NPY2R). Changes in the NPY signaling pathway have been linked to Acute Coronary Syndrome (ACS). Objectives The purpose of this study is to determine the association between variants in the NPY and NPY2R genes, as well as the severity of acute coronary syndrome (ACS). Methods Approximately 221 ACS patients and 278 healthy controls were selected for this study. Four variants in NPY and two variants in NPY2R genes were genotyped using Taqman allelic discrimination and sequencing. The Chi-square and Fisher's exact tests were used to verify the genotype frequencies. The logistic regression analyses were used for the evaluation of the studied variables. Haplotype analysis was used to evaluate the linkage disequilibrium (LD) between the variants (p<0.05). Results An association of NPY c.20T>C variant was found with the ACS group when compared to the healthy group. In the analysis between variants and risk factors in the ACS group, NPY c.84G>A was associated with hypertension. The analysis between TIMI risk showed a significance for NPY c.20T>C between the low and intermediate/high TIMI risk groups. In the haplotype analysis, strong linkage disequilibrium (LD) was found between the variants NPY c.150G>A and NPY c.-485T>C. Conclusion The NPY c.20T>C variant appears to contribute to the development of ACS. The NPY2R c.-1116A>G variant may contribute to the early development of ACS and the NPY c.84G>A variant appears to contribute to the development of hypertension. In addition, the NPY c.20T>C is associated with a protective effect in ACS severity.

SUMMARY: Infraorbital foramen (IOF) located bilaterally within the maxillary bone about 1 cm inferior to the infraorbital margin is a vital landmark when delivering local anesthesia and during surgical interventions in the midface region. A total of 122 infraorbital foramina in 61 cone beam computed tomographic (CBCT) images of 32 females and 29 males in the age range of 17 to 32 were analyzed to determine the shape, direction, presence of accessory foramina, size and the precise position of IOF in relation to the inferior orbital margin (IOM), maxillary midline (MM), lateral nasal wall (LNW), alveolus (ALV) and maxillary teeth in a group of Sri Lankan people. The IOF was oval in shape (80.3 % and 88.5 % on the right and left side, respectively) in a majority of individuals. The infraorbital foramina were located at a mean distance of 5.56 ± 3.95 and 4.91 ± 2.08 mm, below the IOM on the right and left side, 27.13 ± 2.6 and 26.99 ± 2.73 on the right and left side from the mid maxillary line, 11.96 ± 3.45 mm and 12.18 ± 3.35 from the LNW on the right and left side and 29.59 ± 3.59 and 29.65 ± 3.28 above the alveolar crest on the right and left side. There were no statistically significant differences between the left and right sides or between sexes. Majority of IOF (37.5 % and 55.9 % on the right and left side, respectively) were located in the vertical plane passing though the maxillary second premolar tooth.


RESUMEN: El foramen infraorbitario (FIO) ubicado bilateralmente dentro de la maxila, aproximadamente 1 cm inferior al margen infraorbitario, es un punto de referencia vital cuando se administra anestesia local y durante intervenciones quirúrgicas en la región media de la cara. Se analizaron un total de 122 forámenes infraorbitarios en 61 imágenes de tomografía computarizada de haz cónico (CBCT) de 32 mujeres y 29 hombres en un rango etario de 17 a 32 años para determinar la forma, dirección, presencia de forámenes accesorios, tamaño y posición precisa de FIO en relación con el mar- gen orbitario inferior (MOI), la línea mediana maxilar (MM), la pared nasal lateral (PNL), el alvéolo (ALV) y los dientes maxilares en un grupo de personas de Sri Lanka. En la mayoría de los adultos se observó que el FIO tenía forma ovalada (80,3 % y 88,5 % en el lado derecho e izquierdo, respectivamente) Los forámenes infraorbitarios se ubicaron a una distancia media de 5,56 ± 3,95 y 4,91 ± 2,08 mm, por debajo del MOI en los lados derecho e izquierdo; 27,13 ± 2,6 y 26,99 ± 2,73 en el lado derecho e izquierdo desde la línea maxilar mediana, 11,96 ± 3,45 mm y 12,18 ± 3,35 de la PNL en el lado derecho e izquierdo y 29,59 ± 3,59 y 29,65 ± 3,28 por encima de la cresta alveolar en los lados derecho e izquierdo. No hubo diferencias estadísticamente significativas entre los lados izquierdo y derecho o entre sexos. La mayoría de IOF (37,5 % y 55,9 % en el lado derecho e izquierdo, respectivamente) se ubicaron en el plano vertical que pasa por el segundo premolar maxilar.

RÉSUMÉ

The coronavirus disease 2019 (COVID-19) pandemic has emerged as a major threat to all healthcare systems across the globe, and it was declared a public health emergency of international concern by the World Health Organization (WHO). The novel coronavirus affects the respiratory system, producing symptoms such as fever, cough, dyspnea, and pneumonia. The association between COVID-19 and coagulation has been previously reported. Due to several inflammatory changes that occur in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections such as alterations in the levels of clotting factors, platelet activation leads to thrombus formation in coronary and cerebral vessels, leading to myocardial infarction and cerebrovascular accidents, respectively.Unfortunately, the progression of hypercoagulability in COVID-19 is rapid in patients with and without comorbidities. Hence, the proper monitoring of thrombotic complications in patients with COVID-19 is essential to avoid further complications. The implementation of guidelines for antithrombotic treatments based on the presentation of the disease is recommended. This review discusses the symptoms and mechanisms of upregulated coagulation in patients with COVID-19.

RÉSUMÉ

Abstract Introduction Transcription factors are very diverse family of proteins involved in activating or repressing the transcription of a gene at a given time. Several studies using animal models demonstrated the role of transcription factor genes in craniofacial development. Objective We aimed to investigate the association of IRF6 intron-6 polymorphism in the non-syndromic cleft lip with or without palate in a South Indian population. Methods 173 unrelated nonsyndromic cleft lip with or without cleft palate patients and 176 controls without clefts patients were genotyped for IRF6 rs2235375 variant by allele-specific amplification using the KASPar single nucleotide polymorphism genotyping system. The association between interferon regulatory factor-6 gene intron-6 dbSNP208032210:g.G>C (rs2235375) single nucleotide polymorphism and non-syndromic cleft lip with or without palate risk was investigated by chi-square test. Results There were significant differences in genotype or allele frequencies of rs2235375 single nucleotide polymorphism between controls and cases with non-syndromic cleft lip with or without palate. IRF6 rs2235375 variant was significantly associated with increased risk of non-syndromic cleft lip with or without palate in co-dominant, dominant (OR: 1.19; 95% CI 1.03-2.51; p = 0.034) and allelic models (OR: 1.40; 95% CI 1.04-1.90; p = 0.028). When subset analysis was applied significantly increased risk was observed in cleft palate only group (OR dominant: 4.33; 95% CI 1.44-12.97; p = 0.005). Conclusion These results suggest that IRF6 rs2235375 SNP play a major role in the pathogenesis and risk of developing non-syndromic cleft lip with or without palate.


Resumo Introdução Fatores de transcrição constituem uma família de proteínas muito diversa envolvida na ativação ou repressão da transcrição de um gene, em um determinado momento. Vários estudos usando modelos animais demonstraram o papel dos genes do fator de transcrição no desenvolvimento craniofacial. Objetivo Nosso objetivo foi investigar a associação do polimorfismo IRF6 intron-6 na fenda labial não sindrômica com ou sem fenda palatina em uma população do sul da Índia. Método Um total de 173 pacientes com fenda labial não sindrômica com ou sem fenda palatina e 176 controles sem fendas foram genotipados para a variante IRF6 rs2235375 por amplificação alelo-específica utilizando o sistema KASPar de genotipagem de polimorfismo de nucleotídeo único. A associação entre o polimorfismo de nucleotídeo único Fator 6 Regulatório do Interferon (IRF6) intron-6 dbSNP208032210:g.G>C (rs2235375) e o risco de fenda labial não sindrômica com ou sem fenda palatina foi investigado pelo teste qui-quadrado. Resultados Houve diferenças significativas nas frequências de genótipos ou alelos do rs2235375 SNP entre controles e casos com fenda labial não sindrômica com ou sem fenda palatina. A variante IRF6 rs2235375 foi significativamente associada ao aumento do risco de fenda labial não sindrômica com ou sem fenda palatina em modelos codominantes, dominantes (OR: 1,19; IC 95%: 1,03-2,51; p = 0,034) e alélicos (OR: 1,40; IC 95%: 1,04-1,90; p = 0,028). Quando a análise do subgrupo foi realizada, um risco significativamente aumentado foi observado no grupo Fenda Palatina Isolada (OR dominante: 4,33; IC 95%: 1,44-12,97; p = 0,005). Conclusões Esses resultados sugerem que o polimorfismo de nucleotídeo único IRF6 rs2235375 desempenha um papel importante na patogênese e no risco de desenvolvimento de fenda labial não sindrômica com ou sem fenda palatina.

RÉSUMÉ

Background & objectives: Autosomal dominant polycystic kidney disease (ADPKD) is an inherited systemic disorder, characterized by the fluid filled cysts in the kidneys leading to end stage renal failure in later years of life. Hypertension is one of the major factors independently contributing to the chronic kidney disease (CKD) progression. The renin-angiotensin aldosterone system (RAAS) genes have been extensively studied as hypertension candidate genes. The aim of the present study was to investigate the role of angiotensin converting enzyme tagging - single nucleotide polymorphisms (ACE tag-SNPs) in progression of CKD in patients with ADPKD. Methods: In the present study six ACE tagSNPs (angiotensin converting enzyme tag single nucleotide polymorphisms) and insertion/deletion (I/D) in 102 ADPKD patients and 106 control subjects were investigated. The tagSNPs were genotyped using FRET-based KASPar method and ACE ID by polymerase chain reaction (PCR) and electrophoresis. Genotypes and haplotypes were compared between ADPKD patients and controls. Univariate and multivariate logistic regression analyses were performed to assess the effect of genotypes and hypertension on CKD advancement. Mantel-Haenszel (M-H) stratified analysis was performed to study the relationship between different CKD stages and hypertension and their interaction. Results: All loci were polymorphic and except rs4293 SNP the remaining loci followed Hardy-Weinberg equilibrium. Distribution of ACE genotypes and haplotypes in controls and ADPKD patients was not significant. A significant linkage disequilibrium (LD) was observed between SNPs forming two LD blocks. The univariate analysis revealed that the age, hypertension, family history of diabetes and ACE rs4362 contributed to the advancement of CKD. Interpretation & conclusions: The results suggest that the ACE genotypes are effect modifiers of the relationship between hypertension and CKD advancement among the ADPKD patients.
