Sialic acids are alpha-keto acids with nine carbons that are commonly present in the terminal sugars of glycans on glycoproteins and glycolipids on the cell surface. Sialic acids have a role in a variety of physiological and pathological processes by interacting with carbohydrates and proteins, communicating between cells, and acting as cell surface receptors for viruses and bacteria. Several studies have shown the aberrant pattern of sialic acids on cancer cells due to change in their glycosylation status. This pattern may be attributed to various physiological and pathological changes occurring in tumour cells. Hypersialylation in tumours, its involvement in tumour growth, immune evasion and escape from the apoptotic pathway, metastasis formation, and therapeutic resistance have all been fairly well investigated.

One of the major global issues is the urgency of nosocomial infections, biofilm development, and antibiotic resistance. The ESKAPE pathogens are a significant factor in these problems (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species). These pathogens, often known as hospital-acquired infections (HAIs), are common in hospital settings and present one of the most significant difficulties in treatment. The development of biofilms, in which the microbial cells adapt to a multicellular lifestyle by getting trapped inside the extracellular polymeric matrix, is a key biological concept in clinical contexts. For the creation of novel antimicrobial agents, as well as for the repurposing of currently accessible medications or pre-clinical substances and the broader use of combination therapies, it is essential to comprehend the process by which these bacteria build biofilms. The Pathomechanisms of these bacterial biofilm formations and alternate strategies to prevent biofilm formation in hospital management are highlighted in this review. [ABSTRACT FROM AUTHOR]

Background: Due to financial constraints, there are limited treatment options for Aplastic anemia (AA) in developing countries. Aims and Objectives: In the present observational retrospective study, utility of Cyclosporine A (CsA) along with Danazol (an anabolic steroid) in AA was assessed. Materials and Methods: The study included patients of AA treated in our hospital from 2017 to 2020. Results: The present study included total of 95 patients. Out of these, 69 patients (73%) were lost to follow-up. It was observed that, out of 26 patients who could be followed up, 18 (69%) patients responded to the treatment (transfusion independent) at the end of 6 months. Out of 18 patients who had responded, two were very severe AA, 12 were severe AA, and four were non-severe AA patients. Eleven out of 18 (61.1%) females responded, whereas seven out of eight males (87.5%) responded to the treatment. In four patients who received Eltrombopag in addition to CsA-Danazol, three patients responded to the therapy. Conclusion: Treatment with CsA and Danazol may represent a promising therapy for patients with AA, especially in resource limited settings. Further, large-scale collaborative studies are necessary to evaluate such approaches in management of AA. [ABSTRACT FROM AUTHOR]
