Diabetes is one of the most prevalent epidemic metabolic disorders, responsible for a significant amount of physical, psychological and economic loss in human society. Diabetic foot ulcer (DFU) is one of the extreme pathophysiological consequences of diabetes. Bacterial infection is the most important cause of chronic DFU. Bacterial species or their biofilms show multidrug resistance, which complicates DFU and consequently leads to amputation of the infected part. Since the Indian population comprises diverse ethnic and cultural groups, this could influence the aetiology of diabetic foot infections and bacterial diversity. We reviewed 56 articles published from 2005 to 2022 on the microbiology of DFU and extracted the data on study location, number of patients analysed in the study, pathophysiological complications, age of the patients, sex of the patient, type of bacteria, type of infection (mono or polymicrobial), predominant bacteria (Gram-positive or Gram-negative), predominant isolates and multiple drug resistance (tested or not). We analysed data and described aetiological trends in diabetic foot infections and bacterial diversity. The study revealed that Gram-negative bacteria are predominant as compared to Gram-positive bacteria in individuals with diabetes with DFU in India. Escherichia coli , Pseudomonas aeruginosa , Klebsiella sp. and Proteus sp. were the most predominant Gram-negative bacteria, while Staphylococcus aureus and Enterococcus sp. were the major Gram-positive bacteria in DFU. We discuss bacterial infections in DFU in the context of bacterial diversity, sampling methods, demography and aetiology.

Purpose: The aim of the present Aetiology/Risk type and Prognostic type of systematic review is to evaluate the value of Moesin as a biomarker of invasiveness in Oral Squamous Cell Carcinoma patients and to review/assess the available evidence regarding the prospective prognostic association between Moesin and histopathological grading of OSCC to enhance the quality of life and survival rate of oral cancer patients. Method: A systematic wide-range literature search was performed by authors (BS, KS, and DK) till October 2022 using both, electronic search media and manual search by hand, searching appropriate journals as per the focussed guiding question and inclusion/exclusion criteria. Major databases such as Scopus, EMBASE, Web of Science, Cochrane central register for controlled trials, PubMed & Google Scholar were conducted by two calibrated reviewers independently to gauge the association between the prognostic significance of Moesin with histopathological grading of oral squamous cell carcinoma. As this study is based on tissue samples of oral squamous cell carcinoma patients, all the selected studies were mostly, cross-sectional studies, and retrospective in nature. The studies were integrated with this review to gauge the association between the prognostic significance of Moesin with histopathological grading of oral squamous cell carcinoma (OSCC). The review included a total of 7 studies with tissue samples of 645 cases. The prime outcome was to assess the immunoexpression of Moesin among the different histopathological grades i.e well-differentiated SCC, moderately differentiated SCC, and poorly differentiated SCC and the subordinate outcome was to consider the extent of strong immunoexpression characteristics (cytoplasmic, membranous and mixed type) in different grades of OSCC as well as to correlate with morbidity, mortality, and/or 5 years or 10 years survival rate. Results: The results were analyzed and presented narratively using the Critical Appraisal Tools developed by the University Of Oxford; Risk of Bias - Cochrane Risk of Bias tool - RoB 2.0, and GRADE-pro (Grading of Recommendations, Assessment, Development, and Evaluations) which rates the features of the evidence as high, moderate, low and very low. The risk of mortality expressed in terms of Hazard ratio has been elicited as a 1.37 times higher rate of mortality in the advanced histopathological stages of the OSCC cases. As the sample size of this review was insignificant, therefore, the authors have incorporated hazard ratios of some other studies of carcinomas in diverse sites in the body to give a flavor of prognostic outcomes of Moesin. It was observed that Moesin expression in Breast cancer and UADT carcinomas have a higher mortality rate as compared to OSCC and lung carcinoma cases and this decree strengthens our conviction that Moesin expression in the cytoplasm of advanced histopathological stages of cancer can be assumed as a si...

Oral squamous cell carcinoma (OSCC) is the most malignant tumor worldwide with a relatively poor prognosis. This can be due to lack of using new specific biomarkers as a mode of pristine interventional therapy for detecting the lesions at an early stage, thereby not allowing it to proceed to a severe advanced stage. Biomarkers, being the products of malignant cells, can prove to be promising prognostic factors in understanding the molecular pathogenesis of oral cancer. One such biomarker is membrane-organizing extension spike protein (MOESIN). Belonging to the family of ezrin/radixin/MOESIN proteins, MOESIN acts as a structural linker between plasma membrane and actin filament of the cell moiety and is involved in regulating many fundamental cellular processes such as cell morphology, adhesion and motility. This narrative review is a systematic compilation on MOESIN and its role as an emerging biomarker in OSCC.

Background: Type II diabetes mellitus (T2DM) is increasing at an alarming rate in urban as well as rural parts of India. Change in life-style, dietary habits, aging, environmental factors contribute to developing this disorder, T2DM is a polygenic disorder which involves large number of genes interacting with each other and the environment to manifest itself phenotypically. Aims and Objectives: In the present study, we investigated the association of Vitamin D receptor (VDR) and Paraoxonase I (PON I) gene polymorphisms with T2DM patients among rural population in South western Maharashtra. Materials and Methods: The study groups included healthy non-diabetic control group (n = 120), non-obese diabetic group (n = 120), obese diabetic group (n = 120) from the same geographical region. The single nucleotide polymorphisms (SNPs) amongst these groups were studied using Polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP) for VDR and PON I genes. Results and Conclusion: Amongst the studied genes VDR SNP rs1544410 [OR 0.24 (0.1-0.63); P 0.005] and Paraoxonase I SNP rs854560 (OR 0.47 (0.26-0.84); P 0.015) had a protective effect against T2DM for non-obese individuals. Whereas only VDR SNP rs1544410 [OR 0.025 (0.003-0.91); P 0.001] had a protective effect in case of obese individuals. The findings suggest greater gene-gene interaction and gene-environment interactions influence the phenotypic outcomes of genetic polymorphisms.
