Published: September 2021

Aim:
The aim of the study is to evaluate and compare the apical seal obtained with Biodentine after conditioning of root end with three different solutions (HEBP, chitosan, and ethylenediaminetetraacetic acid [EDTA]).

Materials and Method:
Forty-eight maxillary incisors were selected and decoronated. Instrumentation was done with protaper rotary files up to F4 file and obturated with AH plus sealer (Dentsply, Germany) and Protaper gutta-percha cone using lateral condensation technique. The apical part of each root was resected at 90° to the long axis of the root for 3 mm, and retrograde cavity preparation was done in standardized dimensions. The teeth were randomly divided into four groups with 12 samples in each group and later subjected to a standard regimen of 3 ml of respective solutions for 5 min: Group I – 18% HEBP, Group II – 0.2% chitosan, Group III – 17% EDTA, Group IV – saline (control). All teeth were then restored with Biodentine (Septodont, USA). Samples were coated with two coats of nail varnish except in the apical 3 mm which will be immersed in 5 ml of 2% methylene blue dye and stored in incubator for 72 h. The nail varnish will be removed later, and the teeth will be immersed in 35% nitric acid for 72 h. The solutions were then filtered using a fine-grit filter paper and centrifuged at 2000 rpm for 1 min. The solutions thus collected will be used to determine absorbency in ultraviolet-visible spectrophotometer.

Results:
The mean values of absorbance were greatest for Group IV (saline) followed by Group III (17% EDTA), Group II (0.2% chitosan), and Group I (18% HEBP). Group IV (saline) and Group III (17% EDTA) have got statistically significant difference with all the other groups. Group II has got statistically significant difference with all the other groups except Group I.

Conclusion:
Within the limitations of the study, it was concluded that irrigation with newer agents significantly influenced the sealing ability of biodentine. Root-end irrigation with 18% HEBP and 0.2% chitosan showed the least microleakage when compared to 17% EDTA.

Authors: Rashme Vinitha L. , Radhakrishnan Naveen , Das Manoranjan , Srinivasan Muthiah , Prajna N. Venkatesh 
Published: September 2021

Background:
The aim of this study was to compare the donor characteristics, quality of tissues, and utilization rate of corneas collected through Hospital cornea retrieval program (HCRP) and voluntary eye donation (VED).

Methods:
A prospective nonrandomized comparative study of all consecutive donor corneas collected through HCRP and VED during December 2015 to November 2016 was performed. Details of the donor such as age, sex, cause of death, need for medicolegal clearance, death to enucleation time, slit-lamp grading, specular microscopy, and tissue utilization were documented.

Results:
Nine hundred and eighty-five eyes of 493 donors were included in the study, of which 606 (61.5%) eyes belonged to HCRP and 379 (38.5%) eyes in VED. HCRP donors were significantly younger (HCRP: 43.87 ± 19 years; VED: 72.8 ± 13 years; P < 0.001). Males were more common in HCRP (HCRP: 236, 77.6%; VED: 99, 52.2%; P < 0.001). The most common cause of death was road traffic accident (132, 43.6%) in HCRP and cardiovascular disease (93, 49%) in VED. 73.3% (222) of HCRP donors needed medicolegal clearance. Phakic donor eyes were significantly higher in HCRP (HCRP: 561, 92.6%; VED: 184, 48.6%; P < 0.001). Specular microscopy was possible in 396 (65.3%) eyes of HCRP and 129 (34%) eyes of VED. The mean endothelial cell density was 2931 ± 431.1 in HCRP and 2668.6 ± 381.1 in VED. The tissue utilization rate was significantly higher in HCRP (HCRP: 481, 79.4%; VED: 201, 53%; P < 0.001). Eighty-two percent of endothelial keratoplasty, 78.5% of optical penetrating keratoplasty, and 58% of therapeutic keratoplasty were from HCRP donors.

Conclusion:
Donor corneas collected through HCRP have higher tissue utilization.

Authors: Nerli Rajendra B. , Ghagane Shridhar C. , Rangrez Shadab , Chandra Shreya , Thakur Madhukar L. , Gomella Leonard 
Published: September 2021

Introduction:
Cells exfoliated into urine from the bladder can help to diagnose the cancer. The objective of this study was to validate the hypothesis that bladder cancer could be detected noninvasively by a simple and reliable assay targeting genomic VPAC (combined vasoactive intestinal peptide and pituitary adenylate cyclase-activating peptide family of cell surface receptors) receptors expressed on the malignant bladder cancer cells shed in the voided urine.

Methods:
Patients ≥18 years of age with either imaging (ultrasonography/computed tomography [CT])-confirmed bladder tumors or those who have been previously treated for nonmuscle invasive bladder tumors and were visiting the department for check cystoscopy, formed the study group. Freshly voided urine sample was collected from these patients and sent for conventional cytology examination, 5-aminolevulinic acid (ALA) fluorescent urine cytology, and for positivity of VPAC receptors.

Results:
A total of 103 patients were prospectively included in the study. Of these, 65 patients (Group I) presented with image-diagnosed (ultrasonography and/or CT) bladder cancer. The remaining 38 patients (Group II) were previously diagnosed cases of nonmuscle invasive bladder cancer and presented for follow-up and check cystoscopy. The sensitivity for VPAC receptor positivity was 89.23% compared to conventional cytology (63.07%) and 5-ALA fluorescent urine cytology (87.69%). The specificity of VPAC receptor positivity was 100% compared to conventional cytology (100%) and 5-ALA-induced fluorescent cytology (90.47%).

Conclusions:
Our preliminary study shows encouraging results with VPAC receptor positivity studies, which has a high sensitivity when compared to the conventional cytology.

Published: September 2021

Introduction:
Acknowledging the promising role of information and technology, a study was planned to determine the effect of personalized human-centered dietary decision support system (PHCDDSS) on dietary knowledge, attitude, practice (KAP), and mean fasting blood sugar (FBS) among participants with type 2 diabetes mellitus (T2DM).

Materials and Methods:
A community-based randomized control trial was conducted among 400 individuals with T2DM randomized into the 12-month intervention group (PHCDDSS) and 400 to the control (usual care) group.

Results:
In the control and intervention groups, 84.7% and 87.0% participants completed the follow-up at the end of 12 months. Mean knowledge score showed a significant (P = 0.00) declining trend (from 28.3 to 22.2) in the control group, but increasing (from 28.9 to 35.4) in the intervention group. Unlike knowledge, mean attitude score observed a significant declining trend in both the groups but less in the intervention group. The mean FBS (in mg/dL) trend was found to be insignificantly declining in control (199.2–195.4) and intervention (194.8–183.1) groups but the decline was relatively less in control when compared with the intervention group.

Conclusion:
In study participants, PHCDDSS proved to be effective in improving knowledge and attitude toward role of diet in managing T2DM. The intervention showed promising effect in reduction of mean FBS and proportion of individuals with sugar control.

Published: September 2021

Background:
Diabetes is a common co-morbid condition that influences morbidity and mortality in patients with COVID-19 and has been a focus of intense research. However, a systematic assessment of global diabetes research concerning COVID-19 is unavailable.

Aim:
We aimed to provide a bibliometric assessment of research output on diabetes concerning the COVID-19 pandemic.

Materials and Methods:
Publications on diabetes in relation to COVID-19 were retrieved from the Scopus database and analyzed using appropriate bibliometric indicators.

Results:
The publications indexed till January 6, 2021 numbered 762. The share of the top 10 of the 82 countries was 90.6%. The USA, China, India, Italy, and the UK were the most productive countries, with publication share ranging from 11.4% to 17.8%. Brazil, China, Germany, Australia, France, and India registered higher publication impact. The average citations per paper were 7.3, and 19.4% of the publications were funded. The share of publications on type 2 diabetes, type 1 diabetes, and gestational diabetes was 23.2%, 16.5%, and 4.1%, respectively. Diabetic complications, clinical studies, and epidemiology were the most researched aspects of diabetes concerning COVID-19, with 47.9%, 23.3%, and 14.0% share, respectively. Publications on pathophysiology numbered only 93 (12.2%). The most productive organizations were Tongji Medical College, China, Huazhong University, China, Postgraduate Institute of Medical Education and Research, India, and INSERM, France. Obesity and Cholesterol Foundation, India, Imperial College, UK, and The Central Hospital of Wuhan, China were the most impactful organizations. R. Pal, A. Ceriello, and B. Cariou were the most productive authors, whereas A. Misra, R. Gupta, and A.K. Singh were the most impactful. The most active journals were Diabetes Research and Clinical Practice, Diabetes and Metabolic Syndrome: Clinical Research and Reviews, Journal of Diabetes Science and Technology, and Diabetes Care.

Conclusion:
Extensive high-quality research has been conducted on diabetes in relation to the COVID-19 pandemic in developed and developing countries. There is a need to focus on pathophysiological studies to elucidate further the underlying mechanisms that predispose COVID-19-affected diabetes patients to severe disease and death. Our scientometric assessment may help understand the research gaps and guide future research in this field.
Knowledge on Diabetes and Its Determinants among Type 2 Diabetic Subjects in a Low-Resource Setting
Authors: Wahiduzzaman Mohammad , Hossain Sharmin , Islam Sahidul Md. , Banning Friederike , Ali Liaquat , Lechner Andres 
Published: September 2021

Background:
Knowledge about diabetes is the cornerstone of self-management, which is crucial for diabetes care. Improving patients’ knowledge and self-management toward their condition can achieve better control, delay complications, and improve their quality of life. However, there are great variations in the level of knowledge from population to population and this needs to be explored in different ethnic and sociocultural groups for designing appropriate preventive strategies. Due to lack of adequate studies in Bangladesh, this study aimed at assessing diabetes-related knowledge, its determinants and examined which subgroups of patients have the largest knowledge deficits.

Materials and Methods:
This cross-sectional study was carried out among 504 study participants with type 2 diabetes in the outpatient clinic of the Bangladesh Institute of Health Sciences (BIHS) hospital, a tertiary care center in Dhaka, Bangladesh. Sociodemographic information, anthropometric knowledge about diabetes were collected by semistructured, interviewer-administered questionnaires by the face-to-face interview technique. Respondents who achieved a 50% or higher score from a 16-item diabetic knowledge assessment questionnaire were considered to have good knowledge and their counterparts were considered as possessing poor knowledge about diabetes. Descriptive statistics was used to estimate the prevalence of knowledge. A univariate and multivariate logistic regression was carried out to identify significant factors associated with diabetic knowledge.

Results:
The participants’ mean age (±SD) was 52 ± 11years; among them, 57.3% were women, 17.1% were illiterate, and 31.5% belonged to a lower-income family. About one-third of them (29.2%) had good knowledge, and male participants were more educated and had higher diabetes knowledge compared with their counterparts. In particular, gender, education, occupation, monthly family income, and duration of diabetes showed a significant correlation with overall knowledge. On multivariate regression, age, education, duration of diabetes, and family members correlated independently with knowledge.

Conclusions:
On the basis of the current study, it is suggested that about two-third of the patients attending a tertiary care hospital had poor knowledge about diabetes. These results highlight the need for a coordinated educational program with a prioritized focus on older, newly diagnosed, and less educated groups, which reinforces the necessity for patient education.

Published: September 2021

Статья посвящена деятельности П.М. Третьякова как одного из участников антикварного художественного рынка второй половины XIX века. Анализ деятельности П.М. Третьякова на антикварном художественном рынке позволяет сделать общие выводы о его предпочтениях в коллекционировании и принципах, которых он придерживался, таких как целенаправленный поиск произведений признанных художников и желание добиться некоторой законченности в покупке работ отдельных мастеров. Остается открытым вопрос о взаимодействии коллекционера с посредниками в покупке картин. Изучение истории собирательства П.М. Третьякова может дать представление об участниках художественного рынка второй половины XIX века.
In this article, it seems important to pay attention to P.M. Tretyakov as one of the participants in the antique art market of the second part of the 19th century. The goal of this article is to define general conclusions about the preferences of Pavel Tretyakov’s acquires and to identify an area for further work. Analysis of P.M. Tretyakov in the antique art market allows us to draw general conclusions about his preferences in collecting and the principles that he adhered to, such as a focused search for works by recognized artists and the desire to achieve some completeness in the purchase of works by individual masters. The question remains about the interaction of the collector with the art dealer in the acquiring of paintings. Studying the history of collecting P.M. Tretyakov can give an idea of the participants in the art market of the second half of the 19th century and clarify the provenance of some works.

Published: September 2021

Objectives: This study aimed to evaluate the relation between epicardial fat tissue (EFT) thickness and frequent premature ventricular contractions.
Methodology: In this cross-sectional study, patients with no structural heart diseases diagnosed with PVCs on a 24 holter rhythm monitoring were included. EFT thickness was measured by 2-dimensional transthoracic echocardiography. PVCs of more than 10 per hour were considered as frequent PVCs. To investigate the effect of independent variables, univariate logistic regression was performed.
Results: Of total 50 studied patients, 64% were females. The mean age of subjects was 46.8 ± 13.1 years. Twenty-five patients were experiencing frequent PVCs of >10 per hour. In univariate analysis, age (OR= 1.05, 95 % CI; 1.01-1.10, p=0.050), left ventricular end diastolic diameter (LVEDD) (OR= 1.14, 95 % CI; 1.01-1.28, p=0.036) and left atrial (LA) diameter (OR= 1.35, 95 % CI; 1.11-1.62, p=0.002) were significantly associated with developing frequent PVC. EFT thickness was positively correlated with age (r= 0.389, p= 0.005) and inter-ventricular septum thickness in diastole (IVSD) (r= 0.384, p= 0.006). No significant correlation between EFT and PVCs was found (p=0.669).
Conclusion: Patients with frequent PVCs had significantly higher LVEDD and LA diameter. Although patients with higher EFT thickness were more likely to experience frequent PVCs, there was no statistically significant correlation between EFT thickness and frequent PVCs.
