Role of methylprednisolone in the prevention of seroma formation after mastectomy: A randomized controlled trial

Background: Seroma formation after mastectomy with axillary dissection is a major source of morbidity and results in a significant delay in starting the adjuvant treatment. Many different strategies, including the usage of steroids, have been tried to reduce the incidence of seroma with varying outcomes. This study aimed to assess the effect of a single dose of intracavitary methylprednisolone (MP) on seroma formation in patients undergoing total mastectomy with axillary lymph node dissection (ALND). Methods: A randomized controlled trial was conducted at our institute, from January 2018 till June 2019. In the intervention group of 36 patients, 80 mg of MP solution was injected into the wound on post operative day 1. The drain was clamped for 8 hours and then released. In the control group of 36 patients, saline was administered and the drain output was compared between the groups. Results: The mean drain volume in the intervention group was 409.08 mL and in the control group it was 566.97 mL (P < 0.005). The mean drain removal time was 7.86 days and 10.33 days in the intervention and control group, respectively (P < 0.0004). Conclusion: A single dose of intracavitary MP significantly reduced seroma formation and facilitated early removal of drain in patients undergoing total mastectomy with ALND.

Development and Validation of a Bedside Dengue Severity Score for Predicting Severe Dengue in Children

Objective: To develop and validate a bedside dengue severity score in children less than 12 years for predicting severe dengue disease. Methods: We carried out an analysis of data on the clinical and laboratory parameters of patients with confirmed dengue, hospitalized in October, 2019 at our center. A comprehensive patient’s score was developed. Predictive models for severity were built using a forward step-wise method. This model was validated on the data of 312 children with dengue admitted during September- October, 2021. Results: Severe dengue was predicted by the dengue severity score with a sensitivity of 86.75% (95% CI 77.52%-93.19%), specificity of 98.25% (95% CI 95.56-99.52%), a positive predictive value of 95.34% (95% CI 92.18%-97.26%) and a negative predictive value of 94.74% (95% CI 87.16%-97.95%). The overall predictive accuracy was 95.2% (95% CI 92.19%- 97.28%). Conclusion: The proposed bedside dengue severity scoring system was found to have good validity. Validating the score in different settings and patient populations is suggested.

Computer-Aided vaccine design for selected positive-sense single stranded RNA viruses

Spontaneous mutations and lack of replication fidelity in positive-sense single stranded RNA viruses (+ssRNA virus) result in emergence of genetic variants with diverse viral morphogenesis and surface proteins that affect its antigenicity. This high mutability in +ssRNA viruses has induced antiviral drug resistance and ability to overcome vaccines that subsequently resulted in rapid viral evolution and high mortality rate in human and livestock. Computer aided vaccine design and immunoinformatics play a crucial role in expediting the vaccine production protocols, antibody production and identifying suitable immunogenic regions or epitopes from the genome sequences of the pathogens. T cell and B cell epitopes can be identified in pathogens by immunoinformatics algorithms and methods that enhance the analysis of protective immunity, vaccine safety, immunity modelling and vaccine efficacy. This rapid and cost-effective computational vaccine design promotes development of potential vaccine that could induce immune response in host against rapidly mutating pathogens like +ssRNA viruses. Epitope-based vaccine is a striking concept that has been widely employed in recent years to construct vaccines targeting rapidly mutating +ssRNA viruses. Therefore, the present review provides an overview about the current progress and methodology in computeraided vaccine design for the most notable +ssRNA viruses namely Hepatitis C virus, Dengue virus, Chikungunya virus and Coronaviruses. This review also highlights the applications of various immunoinformatics tools for vaccine design and for modelling immune response against +ssRNA viruses.

Spectrum of COVID-19 Disease in Children: A Retrospective Analysis Comparing Wave 1 and Wave 2 from a Tertiary Hospital in South India

Objective To describe COVID-19 in children and the diferences between the two waves. Methods The electronic medical records of children younger than 16 y of age with laboratory-confrmed COVID-19 infection between June 1st 2020 and May 31st 2021 at Christian Medical College, Vellore were retrospectively reviewed. Demographic, clinical, and laboratory data were collected on a predesigned case record form and analyzed. Results A total of 988 children were diagnosed with confrmed COVID-19 during the study period. Of these, there were 585 children diagnosed during the 1st wave (June 2020–Feb 2021) and 403 children during the 2nd wave (March 2021–May 2021). It was found that loose stools and rash were signifcantly more frequent during the 1st wave and fever, cough, coryza, heart rate and temperature were signifcantly more during the 2nd wave. There was no signifcant diference between the two groups in terms of requirement of oxygen therapy, need for ICU admission, duration of ICU stay or hospital stay, or severity of illness. Mortality was signifcantly higher during the 2nd wave (0.3% vs. 2%). Conclusion The COVID-19 pandemic among children during the 1st and 2nd waves were similar in severity, though there was a higher mortality during the 2nd wave.

Multi-level scoring approach to discover multi-targeting potency of medicinal plant phytochemicals against protein targets in SARS-CoV-2 and human ACE-2 receptor

SARS-CoV-2 pandemic has become a major threat to human healthcare and world economy. Due to the rapid spreading and deadly nature of infection, we are in a situation to develop quick therapeutics to combat SARS-CoV-2. In this study, we have adopted a multi-level scoring approach to identify multi-targeting potency of bioactive compounds in selected medicinal plants and compared its efficacy with two reference drugs, Nafamostat and Acalabrutinib which are under clinical trials to treat SARS-CoV-2. In particular, we employ molecular docking and implicit solvent free energy calculations (as implemented in the Molecular Mechanics -Generalized Born Surface Area approach) and QM fragmentation approach for validating the potency of bioactive compounds from the selected medicinal plants against four di?erent viral targets and one human receptor (Angiotensin-converting enzyme 2 -ACE-2) which facilitates the SARS-CoV-2entry into the cell. The protein targets considered for the study are viral 3CL main protease (3CLpro), papain-like protease (PLpro), RNA dependent RNA polymerase (RdRp), and viral spike protein-human hACE-2 complex (Spike:hACE2)including human protein target (hACE-2). Herein, thereliable multi-level scoring approach was used to validate the mechanism behind the multi-targeting potency of selected phytochemicals from medicinal plants. The present study evidenced that the phytochemicals Chebulagic acid, Stigmosterol, Repandusinic acid and Geranin exhibited efficient inhibitory activity against PLpro while Chebulagic acid was highly active against 3CLpro. Chebulagic acid andGeranin also showed excellent target specific activity against RdRp.Luteolin, Quercetin, Chrysoeriol and Repandusinic acid inhibited the interaction of viral spike protein with human ACE-2 receptor. Moreover Piperlonguminine and Piperine displayed significant inhibitory activity against human ACE-2 receptor. Therefore, the identified compounds namely Chebulagic acid, Geranin and Repandusinic acid can serve as potent multi-targeting phytomedicine for treating COVID-19

Genetic diversity and marker trait association for yellow mosaic virus disease in green gram, Vigna radiata (L.) Wilczek

Yellow mosaic virus (YMV) disease is known to cause severe damage in green gram in terms of yield loss. As the resistance is often governed by recessive genes, introgression of such resistance faces some difficulty. DNA molecular markers are reported to be effective in this process. However, validation of such markers is important. Here, we have made an attempt to validate DNA markers associated with YMV disease resistance gene from a diverse group of 26 green gram genotypes. A total of 19 molecular markers were used to assess the susceptibility or resistance against YMV disease. Results show that among the amplified 31 alleles, 21 were polymorphic, with a mean of 1.1.0 per locus. The polymorphism information content (PIC) values ranged from 0.32 to 0.80. Only five markers exhibited higher PIC value (>6.0) and were revealed to be polymorphic, suggesting its utility in marker assisted selection for breeding YMV resistant genotypes in greengram. Dice dissimilarity coefficient among the genotypes exhibited a range of 0.07 to 1.0 which show a wide genetic variation among the genotypes for YMV tolerance. Neighbor-joining cluster analysis has grouped 26 green gram genotypes into 4 main clusters which revealed the existence of genetic dissimilarities among the genotypes. The genotypes AUGG 6, VBN (Gg) 2 and CO (Gg) 8 carried the positive alleles for YMV disease resistance and the allele for susceptibility were found in the genotypes AUGG 12, AUGG 15, AUGG 17 and AUGG 19. Single marker analysis indicated that there was correlation between the markers and the disease reaction in the field with exceptions. The findings revealed that the SSR markers CEDG180 and YR4 could be used to screen germplasm in order to discriminate the YMV resistant genotypes from the susceptible genotypes in marker assisted selection.

Modified protocol to overcome in vitro recalcitrance of premature micro-shoots abscission by silver supplementation in Kinnow mandarin (Citrus nobilis L. × Citrus deliciosa T.)

The present study focused on alleviating the issue of premature abscission of micro-shoots emerged from the cultured nodal segments in Kinnow mandarin. To resolve the problem, explants of different maturity stages, culture media, growth regulator combinations and ethylene inhibitors (silver compounds) were evaluated. Hardwood stage was observed to be the most efficient explant maturity stage to boost the vigorous early shoot emergence on MS (Murashige and Skoog) medium. Addition of GA3 (Gibberellic acid) 10 mg L?1 resulted in delayed abscission. Further reduction in abscission rate and healthy shoot growth were observed when subculturing of micro-shoots was done on MS medium supplemented with BAP 2.5 mg L?1, GA3 10 mg L?1 and silver thiosulfate 5 mg L?1. This modified procedure could be effectively utilized for mass multiplication as well as crop improvement in Kinnow mandarin.

Increased susceptibility of cystic fibrosis airway epithelial cells to ferroptosis

BACKGROUND: Defective chloride transport in airway epithelial cells (AECs) and the associated lung disease are the main causes of morbidity and early mortality in cystic fibrosis (CF). Abnormal airway iron homeostasis and the presence of lipid peroxidation products, indicative of oxidative stress, are features of CF lung disease. RESULTS: Here, we report that CF AECs (IB3-1) are susceptible to ferroptosis, a type of cell death associated with iron accumulation and lipid peroxidation. Compared to isogenic CFTR corrected cells (C38), the IB3-1 cells showed increased susceptibility to cell death upon exposure to iron in the form of ferric ammonium citrate (FAC) and the ferroptosis inducer, erastin. This phenotype was accompanied by accumulation of intracellular ferrous iron and lipid peroxides and the extracellular release of malondialdehyde, all indicative of redox stress, and increased levels of lactate dehydrogenase in the culture supernatant, indicating enhanced cell injury. The ferric iron chelator defer-oxamine (DFO) and the lipophilic antioxidant ferrostatin-1 inhibited FAC and erastin induced ferroptosis in IB3-1 cells. Glutathione peroxidase 4 (GPX4) expression was decreased in IB3-1 cells treated with FAC and erastin, but was unchanged in C38 AECs. Necroptosis appeared to be involved in the enhanced susceptibility of IB3-1 AECs to ferroptosis, as evidenced by partial cell death rescue with necroptosis inhibitors and enhanced mixed lineage kinase domain-like (MLKL) localisation to the plasma membrane. CONCLUSION: These studies suggest that the increased susceptibility of CF AECs to ferroptosis is linked to abnormal intracellular ferrous iron accumulation and reduced antioxidant defences. In addition, the process of ferroptotic cell death in CF AECs does not appear to be a single entity and for the first time we describe necroptosis as a potential contributory factor. Iron chelation and antioxidant treatments may be promising therapeutic interventions in cystic fibrosis.

Screening Of In Vitro Antiviral Activity Of Purified Terpenoid Extracts Of Selected Sea Weeds Against Chikungunya Virus

Currently, the search of novel phytochemicals with unique biological potentialities is a pre-requisite for the designing ideal drugs for the human kind. Sea weeds are bioresources with a broad spectrum of medicinal properties with minimal side effects. Kerala, the Southern state of India reported high incidence of Chikungunya virus (CHIKV) infections in the last several tears. No specific virucidal therapy or effective vaccines are available. This emphasizes the need of searching for phytochemicals as drugs with less cost and more effective. Therefore, an attempt was made in screening purified terpenoid extracts of selected sea weeds as anti-CHIKV potential. In this study the terpenoids composition from the red algae Hypnea musciformis, Kappaphycus alvarezii and Gracillaria dura were identified and analyzed by thin layer chromatography and Gas chromatography- Mass spectrum. The methanolic extract of seaweeds was purified by column chromatography and each fraction was eluted by using petroleum ether and ethyl acetate as solvent combination. The analysis of the purified fraction of H. musciformis and K. alvarezii revealed the presence of 8 terpenoid fractions, and G. dura showed only 4 major components respectively. Vero cell lines were employed in the antiviral assays, infected to CHIKV, and treated with varied doses of purified terpenoid extracts. In the antiviral activity, terpenoid extracts of G. dura showed remarkable and promising EC50 inhibitory effect at 1.25 μg/ml. Further, the terpenoid extracts displayed efficient virucidal activity against CHIKV (inhibit around 90%) with 5 μg/ml dosage. As the last phase, terpenoid extracts added at time intervals of 0, 1, 2, 3 post-infection periods still maintained a significant inhibitory potential against CHIKV viral replication. Thus, the overall study suggests that the terpenoid extracts of G. dura may be effectively used in the prevention and treatment of CHIKV infections. Clinical studies may be warranted for designing a promising new anti-CHIKV drug.

In Vitro Antioxidant Potentiality Of Purified Anthocyanin From Floral Petals Of Wild Balsam Species

Phenolics are the largest group of phytochemicals ubiquitous in plant species with considerable interest economically. Recently, search of novel polyphenols increasingly becomes an area of intensive pharmacological research due to their multiple bioactive features such as antioxidant, antimicrobial, anti-carcinogenic, anti-viral and anti-inflammatory potentialities. Anthocyanins are flavonoid group of polyphenols, a group predominant in flowers, fruits and vegetables. The flavonoids, perhaps the unique single group of phenolics in foods, comprise a group of over 4200 C15 aromatic molecules with multiple structural patterns. The functions of anthocyanins as medicinal have been well-accepted in folk medicine throughout the world. In fact, these molecules are connected to an amazingly broad-based range of health benefits. In this juncture, the aim of this work was to evaluate the antioxidant activities of purified anthocyanin from wild balsam species. Initially, anthocyanin was extracted from floral leaves of wild balsam species and purified by chromatographic techniques. Subsequently, it was subjected to NMR and LC MS analysis. The major fractions identified were hesperidin, dimethoxy antirrhinin and trimethoxy antirrhinin. Further, the anthocyanin extracts were subjected to in vitro protocols like 2,2’-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical cation, DPPH scavenging assay, ferric reducing antioxidant power (FRAP), beta carotene bleaching assay, metal chelating and H2O2 scavenging power. Interestingly, ABTS, FRAP analyzes yielded significant results as compared to others. The data were comparable with that of synthetic antioxidants like ascorbate and catechin. Meanwhile, beta carotene and H2O2 scavenging assay showed moderate results. DPPH and metal chelating protocols displayed the values 71% and 64% respectively at 25 µg/ml concentration. This study provides model systems for the evaluation of natural antioxidants like anthocyanin. Future in vivo clinical studies are warranted to confirm the obtained data.
