Aims and Objectives: The incidence of postoperative liver dysfunction is high in patients undergoing double-valve replacement - mitral and aortic valve replacement (DVR). This study aims to evaluate N-acetylcysteine's free radical scavenging property (NAC) to prevent postoperative liver dysfunction in these patients, thus affecting overall clinical outcomes., Methods: A single-center, prospective, randomized, double-blinded interventional study of 60 patients divided into two groups of 30 each. Group N received prophylactic intravenous NAC, and Group C received volume-matched 5% dextrose. Data comprised demographics, liver function tests (LFT), renal function tests (RFT), vasoactive-inotropic scores (VIS) score, and C-reactive protein (CRP) at various time intervals. Postoperative parameters such as ventilation duration, length of stay in ICU (LOS-ICU), length of hospital stay (LOHS), atrial fibrillation (AF), acute kidney injury (AKI) requiring hemodialysis, and mortality were noted. Statistical analysis was performed with the Student's t-test and Chi-square test (SPSS 22 software)., Results: All postoperative LFT parameters (total bilirubin, serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvate transaminase (SGPT), and alkaline phosphatase (ALP)) were significantly lower (P < 0.05) at 24, 48, and 72 hours in Group N compared to Group C. RFT and VIS scores were lower in Group N; however, were not statistically significant except for Serum Creatinine at 48 hours (P = 0.0478). Ventilation duration (P = 0.0465) and LOS-ICU (P = 0.0431) were significantly lower in Group N. Other outcomes like AF, LOHS, and mortality were lower in Group N but were not statistically significant., Conclusion: Our study showed that prophylactic administration of NAC in patients undergoing DVR is associated with a reduction in the incidence of postoperative liver dysfunction with a positive impact on postoperative outcomes., (Copyright © 2024 Copyright: © 2024 Annals of Cardiac Anaesthesia.)

Abstract: We report the case of a 48 year old man brought-in-dead to the trauma unit following an alleged accidental fall from a multi-storied building. Autopsy findings were consistent with traumatic injuries to the head, chest and spine. Incidentally, a bit of the diaphragm with a pearly white lobulated mass over the pleural surface was observed. Histopathological examination detected a calcifying fibrous pseudotumour (CFPT), confirmed by positive immunostaining for cluster of differentiation protein-34 (CD34) and vimentin (focally). CFPTs are slow-growing pseudotumours that are clinically benign with extremely low rate of recurrence and this might just be the first reported case of CFPT on the diaphragm. This shall further aid clinicians to diagnose these rare yet significant soft tissue tumors in uncommon sites., (Copyright © 2023 Copyright: © 2023 Indian Journal of Pathology and Microbiology.)

Abstract: Leprosy, an ancient disease, continues to be a public health concern as it remains endemic in several countries. After reaching the elimination target (1/10,000) as a public health problem in 2005 in India, around 1.2 lakh cases have been detected every year over the last decade indicating active transmission of leprosy bacillus (Mycobacterium leprae). Single-nucleotide polymorphisms (SNPs), genomic insertions/deletions and variable-number tandem repeats (VNTRs) have been identified as genetic markers for tracking M. leprae transmission. As the leprosy bacilli cannot be cultured in vitro, molecular testing of M. leprae genotypes is done by polymerase chain reaction-based sequencing which provides a practical alternative for the identification of strains as well as drug resistance-associated mutations. Whole-genome sequencing (WGS) of M. leprae directly from clinical samples has also proven to be an effective tool for identifying genetic variations which can further help refine the molecular epidemiological schemes based on SNPs and VNTRs. However, the WGS data of M. leprae strains from India are scarce, being responsible for a gross under-representation of the genetic diversity of M. leprae strains present in India and need to be addressed suitably. Molecular studies of leprosy can provide better insight into phylogeographic markers to monitor the transmission dynamics and emergence of antimicrobial resistance. An improved understanding of M. leprae transmission is essential to guide efficient leprosy control strategies. Therefore, this review compiles and discusses the current status of molecular epidemiology, genotyping and the potential of genome-wide analysis of M. leprae strains in the Indian context., (Copyright © 2024 Copyright: © 2024 Indian Journal of Medical Research.)

Background: Dental caries is a dynamic process. By using therapeutic agents, early, noncavitated lesions and caries limited to the enamel can be stopped or even remineralized. For the remineralization of the initial carious lesion, many nonfluoridated remineralizing agents were investigated., Objectives: An observational study to assess the remineralizing efficacy of tricalcium phosphate (TCP), nano-hydroxyapatite (nHAp) and ozone remineralizing agents on the artificial carious lesion., Methodology: In this observational research, the artificial carious lesion was produced on extracted 40 premolar teeth. Later, remineralizing agents (Group A: nHAp, Group B: TCP, Group C: Ozone remineralizing agents, Group D: Control group (Deionized water) were used to remineralize demineralized teeth. Utilizing the Vickers Hardness Number, the level of demineralization and remineralization was assessed. Later these readings were statistically assessed using the Tukey's HSD (honestly significant difference) and ANOVA tests in SPSS version 21.0. The P value was set at 0.05 or less., Results: After demineralization, there was a decrease in enamel microhardness values, with 32% in Group A, 26% in Group B, 22% in Group C, and 21% in Group D, respectively. From the baseline to demineralization, there was a statistically significant decrease in microhardness across all groups. After remineralization, Groups A, B, and C experienced an increase in microhardness while Group D experienced no changes. This showed that Group A had the highest remineralization percentage, followed by Group B and Group C., Conclusion: nHAp and TCP had the greater remineralizing ability, which can be used to manage initial carious lesions., (Copyright © 2024 Copyright: © 2024 Indian Journal of Dental Research.)

Background: Secondary bacterial infections during COVID-19 hospitalization have been reported in about 6-15% of patients., Aims: To study the secondary bacterial infections that affected the COVID-19 patients during their hospitalisation and to unearth the bacteriological profile of samples obtained after their demise., Settings and Design: This prospective study was carried out at a COVID-19 dedicated, apex tertiary care centre in North India from July 2020 to April 2021., Methods and Materials: Samples of 268 patients were considered for the study. Nasopharyngeal swab specimen, blood, and tissue (lung) were collected from the deceased body as early as possible and processed., Statistical Analysis: Statistical analyses were performed using STATA version 11.1 (Stata Corp., College Station, TX, USA)., Results: A total of 170 samples were received from patients before their death, which included blood, urine, respiratory samples, pus, and cerebrospinal fluid. Forty-four pathogens were isolated, which consisted of Acinetobacter baumannii (43.1%), Klebsiella pneumoniae (36.3%), Escherichia coli (11.3%), and Pseudomonas aeruginosa (4.5%), Enterococcus faecium (4.5%). Two hundred fifty-eight samples were collected from the deceased bodies wherein the nasopharyngeal sample was highest, followed by tissue and blood. A total of 43 pathogens were isolated among them which included A. baumannii (44.1%), followed by K. pneumoniae (25.5%), E. coli (20.9%), P. aeruginosa (6.97%) and Enterobacter cloacae (2.3%). All these isolates were highly resistant to antimicrobials., Conclusions: In our study, bacterial profiles in antemortem and postmortem samples were found to be similar, suggesting that resistant pathogens may be the cause of mortality in COVID-19 infected hospitalised patients.

Bipolar affective disorder (BPAD) is a major psychiatric illness impairing the quality of life. The etiology of BPAD is influenced by different factors possibly related to gene-environment interactions. Approximately 30% to 50% of individuals with BPAD have experienced some traumatic event in childhood. Serious adverse experiences that children may suffer early in life are often described as childhood trauma (CT). It includes physical, emotional, and sexual abuse and physical and emotional neglect. CT is linked with an elevated risk of developing BPAD. Childhood adversities play a role in modulating the early onset of illness, increased number of depressive episodes, increased suicide attempts, and other clinical severity of BPAD. Hospital-based studies comprising heterogeneous populations had researched the specific role of each trauma subtype as a predisposing factor for BPAD. Identifying and addressing CT through early intervention methods may prevent the future development of chronic disorders like BPAD. This review article is an attempt to explore and highlight the existing literature regarding the association of different subtypes of CT with BPAD., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Industrial Psychiatry Journal.)

Summary: Effective antimicrobials play an important element in modern medicine's success in treating infections, without which the patients would be put at risk. Along with the naturally occurring process of antibiotic resistance, the misuse/overuse of these antibiotics also leads to them losing their effectiveness. It limits the treatment options as the microbe that had previously been sensitive becomes resistant. This bibliometric study was performed by searching the Scopus database according to a specific search strategy. A total of 4200 articles were retrieved from the search, and after applying inclusion and exclusion criteria, 1355 articles were included in the study. All of the bibliometric variables examined in this study revealed significant growth in this research field, especially during COVID-19, in terms of increasing scientific output and research collaboration. The study findings indicate an adequate quality and amount of antimicrobial resistance (AMR) research on microbiology and pharmacodynamics in India, whereas more research needs to be conducted on measures to tackle AMR, its public health, and policy aspects., (Copyright © 2023 Copyright: © 2023 Indian Journal of Public Health.)

Background Objectives: Polycystic ovary syndrome (PCOS) is characterized by chronic ovulatory dysfunction, hyperandrogenism and polycystic ovary morphology (PCOM). Although hyperandrogenism is one of the major features of PCOS, it is rarely observed in southeast Asia. Recently, however, there has been growing evidence on association of anti-Müllerian hormone (AMH) with PCOS. The objective of this study was to investigate the diagnostic potentials of AMH in PCOS individuals., Methods: This case-control study included a total of 131 women with PCOS and 49 healthy controls who were enrolled after the exclusion of secondary causes of PCOS. Serum AMH was measured using an ultra-sensitive AMH ELISA kit in addition to other diagnostic biomarkers. Statistical analyses was carried out using the Student's t test, Wilcoxon rank-sum test, receiver operating characteristic (ROC) curve analysis, Spearman's rank correlation test and multivariable binary logistic regression analysis., Results: The median AMH values were 8.5 ng/ml and 2.5 ng/ml in the study group and controls, respectively ( P <0.001). The normal cutoff value of 4.1 ng/ml for AMH was derived from ROC curve analysis. With a 4.1 ng/ml cut-off value, high levels of AMH was found in about 84 per cent of PCOS cases. However, no significant difference in AMH level was noted between age groups (<20 vs . ≥20 yr), body mass index (BMI) (<25 vs . ≥25 kg/m 2 ) and PCOM types. The area under the ROC curve (AUC) for AMH yielded diagnostic range values. In total PCOS cases, AUC was 0.93 (95% CI: 0.88 and 0.96), and in phenotype A PCOS cases, AUC was 0.96 (95% CI: 0.91 and 0.98). The correlation test also showed no association with BMI, the FG score, PCOM, free androgen index, androstenedione, dehydroepiandrosterone sulphate and luteinizing hormone. However, a weak correlation was observed with testosterone in total PCOS cases and with DHT as well as age in phenotype A PCOS cases. The prediction model for PCOS using multivariable binary logistic regression analysis showed AMH as the best marker., Interpretation Conclusions: The results of this study suggest that AMH can be considered as the most promising biomarker in PCOS women, particularly with phenotype A and phenotype D., (Copyright © 2023 Copyright: © 2023 Indian Journal of Medical Research.)

Salt plays a critical role in India's past as well as its present, from Dandi March to its role as a vehicle for micronutrient fortification. However, excess salt intake is a risk factor for high blood pressure and cardiovascular diseases (CVDs). Indians consume double the World Health Organization recommended daily salt (<5 g). India has committed to a 30 per cent reduction in sodium intake by 2025. Evidence based strategies for population sodium intake reduction require a moderate reduction in salt in - home cooked foods, packaged foods and outside-home foods. Reducing the sodium content in packaged food includes policy driven interventions such as front-of-package warning labels, food reformulation, marketing restrictions and taxation on high sodium foods. For foods outside of the home, setting standards for foods purchased and served by schemes like mid-day meals can have a moderate impact. For home cooked foods (the major source of sodium), strategies include advocacy for reducing salt intake. In addition to mass media campaigns for awareness generation, substituting regular salt with low sodium salt (LSS) has the potential to reduce salt intake even in the absence of a major shift in consumer behaviour. LSS substitution effectively lowers blood pressure and thus reduces the risk of CVDs. Further research is required on the effect of LSS substitutes on patients with chronic kidney disease. India needs an integrated approach to sodium reduction that uses evidence based strategies and can be implemented sustainably at scale. This will be possible only through scientific research, governmental leadership and a responsive evidence-to-action approach through a multi-stakeholder coalition.
