The Spectrum of Central Nervous System Tumors at a Tertiary Care Center Primarily Serving a Rural Population.

Background Central nervous system (CNS) tumors cause significant mortality and morbidity in all age groups. There was no data about the histological spectrum of all CNS tumors in the tertiary care center serving primarily the rural population of Uttar Pradesh. Aims and objectives The present study aimed to describe the histopathological spectrum of all CNS tumors reported in a rural tertiary care center at Saifai, Uttar Pradesh. It also aimed to provide an overview of the descriptive epidemiology of CNS tumors. Material and methods This was a retrospective, cross-sectional study. The study duration was three years. A total of 115 cases of CNS tumors were studied during that period. Cases were classified according to their histological types, and results were analyzed. Results The most common histological group was neuroepithelial tumors, with 53 cases (46.08%). This group had 36 cases of astrocytic tumors (31.3%), three cases of oligodendroglial tumors (2.6%), five cases of oligoastrocytic tumors (4.34%), five cases of ependymal tumors (4.34%), and four cases of embryonal tumors (3.47%). The second most common tumor was meningeal tumors, with 32 cases (27.82%). The male/female ratio (M/F) ratio was 0.7. Females were found to be more affected by almost all histologic categories. Most meningiomas (89.6%) were of World Health Organization (WHO) grade I (26 cases out of 29). Astrocytic tumors showed WHO grade I, II, III, and IV tumors in two cases (5.5%), twelve cases (33.3%), four cases (11.1%), and eighteen cases (50%), respectively. In the younger age group (0-20 years), ependymoma and medulloblastoma were most common, followed by pilocytic astrocytoma and schwannoma. Conclusion In this region, neuroepithelial tumors were seen more commonly than meningioma. Females were found to be more affected by CNS tumors. This study has provided relevant data, which can be used for research and better patient management. Further studies with the incorporation of advanced radiological investigation and immunohistochemistry have been recommended.

Pharmacist roles in antimicrobial stewardship: a qualitative study from India, South Africa and the United Kingdom.

Objective: To explore pharmacist roles in antimicrobial stewardship (AMS) in India, South Africa (SA), United Kingdom (UK) and the factors that contribute to their participation in the programme in these countries. Methods: Data were collected between April 2019 and March 2022 through semi-structured interviews with key AMS stakeholders from India (Kerala); SA (Western Cape province) and the UK (England). Interviews were conducted face to face or via Zoom and Skype platforms, audio recordings were transcribed verbatim and thematically analysed using a grounded theory approach aided by NVivo 12 software. Results: We interviewed 38 key AMS stakeholders (pharmacists and doctors). India and the UK have dedicated AMS pharmacists (Doctor of Pharmacy and Master of Pharmacy graduates with opportunities for additional post-graduate qualifications respectively). Pharmacists in the UK lead AMS programmes, while in India, predominantly in the private sector, pharmacists drive AMS in collaboration with clinicians. In SA, pharmacists (Bachelor of Pharmacy graduates) participate in AMS out of their own commitment in addition to their pharmacy responsibilities. Private sector pharmacists drive AMS while public sector pharmacists participate in clinician-led AMS programmes. Current pharmacy curricula do not provide adequate training in AMS, and this limitation shapes pharmacist roles and acceptance in AMS among clinicians in India and SA. Support of mentors (doctors/senior pharmacists) and self-motivated learning are key factors for effective pharmacist involvement in AMS. Conclusions: A contextually developed, standardized and accessible AMS training programme along with pharmacy curricula modification to include AMS, may facilitate prominent pharmacist roles in AMS.

Current state of education, training and practices in antimicrobial stewardship among pharmacy students: A cross-sectional survey from Kerala, India.

PURPOSE: Pharmacists are recognised in guidelines from across the globe as key stakeholders in antimicrobial stewardship (AMS) initiatives. The current study aims to assess the current practices and level of training and education in relation to AMS among pharmacy students from Kerala, India. METHODS: A cross-sectional web-based survey was developed and disseminated among doctor of pharmacy 5th year students and interns from selected pharmacy colleges across Kerala through key informants. Descriptive statistics were used to analyse the responses. RESULTS: The response rate was 34.8% (157/450). Whilst the majority of respondents (89.8%, 141/157) recalled being taught about antimicrobial resistance (AMR) as part of the pharmacy curricula, 84.7% (133/157) believed they didn't have sufficient knowledge about AMR. Most of the respondents (64.9%, 102/157) had not received any AMS training. Clinical posting in AMS was the preferred mode of training suggested by most respondents. Respondents who audited antimicrobials as part of their clinical postings (77.9%, 88/113) reported their main responsibility was review of patient records for assessing the appropriateness of antimicrobials (68.2%, 60/88). Inappropriate selection of antimicrobials was the most common error identified by respondents (38.1%, 43/113) and the key method of communicating their recommendation was informing the prescriber in person (46%, 52/113). CONCLUSION: Whilst pharmacy students are reviewing antimicrobial prescriptions as part of their clinical postings, their education and training in AMR and AMS remain low. The inclusion of practical clinical training for pharmacy students as part of their curricula can be a cost-effective way to promote AMS initiatives.

Evaluating the Quality of Life of Beneficiaries After Providing Financial Aid by a Multi-specialty Tertiary Care Hospital.

Background Financial aid programs offered by multi-specialty tertiary care hospitals play a crucial role in ensuring equitable access to healthcare. This study investigates the effect of financial aid on the quality of life (QoL) of beneficiaries, aiming to provide a comprehensive understanding of the multifaceted relationship between healthcare support and overall well-being. Aim The study's objectives included assessing changes in pre- and post-aid QoL, identifying influencing factors, understanding beneficiary experiences, and evaluating the effectiveness of financial aid programs. Methods The study adopted quantitative assessments through QoL questionnaires developed based on the WHO BREF questionnaire and insights obtained through interviews. A representative sample of beneficiaries was selected, informed consent was obtained, and an institutional ethical certificate was also obtained. Results The findings overwhelmingly support the alternative hypothesis. The alternative hypothesis was that after receiving financial support, recipients' quality of life would increase. Quantitative analysis revealed a statistically significant enhancement in the QoL of beneficiaries across physical, mental, and social well-being domains. The quality of life scores of patients before and after receiving the support was statistically tested using a paired t-test, and the quality of life score has improved significantly with a p-value of 4.156 × 10-28 (p value<0.001). The comparison of quality of life scores of the control group with the patient's group before getting the support was tested using an independent sample t-test and found to be non-significant (p=0.496), while a similar comparison between the control group and the patient's group after receiving the support was found to be statistically highly significant with a p-value of 8.721 × 10-28 (p-value<0.001). Conclusions This research demonstrates the substantial impact of financial aid on the QoL of beneficiaries in a multi-specialty tertiary care hospital setting. It underlines the importance of addressing economic barriers and providing patient-centered, holistic support. These insights have broader implications for healthcare policy and practice, promoting a more comprehensive approach to patient well-being.

Comparison of clinical performance of obturating materials in pulpectomies: A randomized clinical trial.

BACKGROUND: Chemomechanical debridement is insufficient to disinfect all bacteria from the root canals of primary teeth, and obturation of canals with an appropriate material thus acquires excellent importance and remains a critical step in the ultimate success of pulpectomy. AIM: The aim of the study was to compare and evaluate Endoflas, Metapex, and a mixture of calcium hydroxide (CH) and zinc oxide (ZnO) as obturating materials (OMs) in primary mandibular second molars. MATERIALS AND METHODS: Seventy-five mandibular second primary molars requiring pulpectomies were identified in children aged 4-8 years. They were randomly allocated to the three treatment groups according to the type of OM received using the block randomization technique. After the completion of chemomechanical debridement, the canals were filled with Endoflas, Metapex, and CH-ZnO mixture, respectively. The intergroup clinical and radiographic comparison was made based on Coll and Sadrian criteria to decipher their clinical performance at 1, 3, and 6 months. RESULTS: No statistically significant differences between the groups were observed at any evaluation time interval (P > 0.05). At 6 months, the clinical success rates were 95.2% in Endoflas, 96% in Metapex, and 95.8% in the CH and ZnO mixture groups, respectively. The materials, however, behaved differently in different clinical situations. CONCLUSION: Based on the observations, all three OMs showed similar clinical success in maintaining tooth functioning, but their use can be restricted to indications. However, prospective studies with longer follow-ups with more stringent eligibility criteria are required to reach more definitive conclusions.

Genome-wide runs of homozygosity signatures in diverse Indian goat breeds.

The present study analyzed ROH and consensus ROH regions in 102 animals of eleven diverse Indian goat (Capra hircus) breeds using whole genome sequencing. A total of 51,705 ROH and 21,271 consensus regions were identified. The mean number of ROH per animal was highest in the meat breed, Jharkhand Black (2693) and lowest in the pashmina breed, Changthangi (60). The average length of ROH (ALROH) was maximum in Kanniadu (974.11 Kb) and minimum in Tellicherry (146.98 Kb). Long ROH is typically associated with more recent inbreeding, whereas short ROH is connected to more ancient inbreeding. The overall ROH-based genomic inbreeding (FROH) was highest for Jharkhand Black (0.602) followed by Kanniadu (0.120) and Sangamneri (0.108) among all breeds. FROH of Jharkhand Black was higher than Kanniadu  up to 5 Mb ROH length category. However, in > 20 Mb ROH length category, Kanniadu (0.98)  exhibited significantly higher FROH than Jharkhand Black (0.46). This  implies that Kanniadu had higher levels of recent inbreeding than Jharkhand Black. Despite this, due to the presence of both recent and ancient inbreeding, Jharkhand Black  demonstrated higher overall FROH compared to Kanniadu. ROH patterns revealed dual purpose (meat and dairy) and pashmina breeds as less consanguineous while recent inbreeding was apparent in meat breeds. Analysis of ROH consensus regions identified selection sweeps in key genes governing intramuscular fat deposition, meat tenderisation, lean meat production and carcass weight (CDK4, ALOX15, CASP9, PRDM16, DVL1) in meat breeds; milk fat percentage and mammary gland development (POLD1, NOTCH2, ARHGAP35) in dual purpose (meat and dairy) breeds; while cold adaptation and hair follicle development (APOBEC1, DNAJC3, F2RL1, FGF9) in pashmina breed. MAPK, RAS, BMP and Wnt signaling pathways associated with hair follicle morphogenesis in Changthangi were also identified. PCA analysis based on ROH consensus regions revealed that meat breeds are more diverse than other goat breeds/populations.

Mentorship as an overlooked dimension of research capacity strengthening: how to embed value-driven practices in global health.

Mentorship in global health remains an overlooked dimension of research partnerships. Commitment to effective mentorship models requires value-driven approaches. This includes having an understanding of (1) what mentorship means across different cultural and hierarchical boundaries in the health research environment, and (2) addressing entrenched power asymmetries across different aspects including funding, leadership, data and outputs, and capacity strengthening. Existing guidance towards equity and sustainability fails to inform how to navigate complex relationships which hinder effective mentorship models. We focus this perspective piece on human capacity strengthening in research partnerships through mentorship. Using a case study of a research partnership, we describe the lessons learnt and the challenges faced in the mentor mentee relationship while maintaining an effective and sustainable partnership. Human capacity strengthening must research projects and collaborations, and recognise local leadership and ownership. To be transformative and effective, practices need to be driven by common values across research teams.

Markers of Oxidative Stress and Tyrosinase Activity in Melasma Patients: A Biochemical Investigation.

BACKGROUND: Melasma is a skin hyperpigmentary disorder that develops over time. Genetic factors, oxidative stress, female sex hormones, and UV light may all play a role in the disorder's progression. AIMS: To compare the levels of oxidative stress and tyrosinase activity in melasma patients with healthy volunteers. METHODS: After written consent, 130 patients were enrolled in a case-control study. 65 cases were of melasma disorder, and 65 were served as control. Homogenized skin tissues were taken and used to estimate superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH), glutathione peroxidase (GPx) (antioxidants), malondialdehyde (MDA) and tyrosine hydroxylase (TH). RESULTS: Melasma patients had lower basal levels of systemic antioxidants than healthy subjects. Tyrosinase activity was shown to be greater in lesional skin than in non-lesional skin. In controls, there was a good positive relationship between TH and MDA and an excellent negative relationship between GPx and GSH. In melasma patients, there were significant associations between CAT, GPx, SOD and MDA. CONCLUSIONS: Increased oxidative stress may affect tyrosinase activity and eumelanin synthesis via the anabolic pathway of melanin synthesis, according to our findings. In conclusion, we discovered a negative relationship between antioxidants and tyrosinase activity.

Antimicrobial resistance and the great divide: inequity in priorities and agendas between the Global North and the Global South threatens global mitigation of antimicrobial resistance.

To limit the catastrophic effects of the increasing bacterial resistance to antimicrobials on health, food, environmental, and geopolitical security, and ensure that no country or region is left behind, a coordinated global approach is required. In this Viewpoint, we argue that the diverging resource availabilities, needs, and priorities of the Global North and the Global South in terms of the actions required to mitigate the antimicrobial resistance pandemic are a direct threat to success. We argue that evidence suggests a need to prioritise and support infection prevention interventions (ie, clean water and safe sanitation, increased vaccine coverage, and enhanced infection prevention measures for food production in the Global South contrary to the focus on research and development of new antibiotics in the Global North) and to recalibrate global funding resources to address this need. We call on global leaders to redress the current response, which threatens mitigation of the antimicrobial resistance pandemic.

Epidemiology and preventability of hospital-onset bacteremia and fungemia in 2 hospitals in India.

OBJECTIVE: Studies evaluating the incidence, source, and preventability of hospital-onset bacteremia and fungemia (HOB), defined as any positive blood culture obtained after 3 calendar days of hospital admission, are lacking in low- and middle-income countries (LMICs). DESIGN, SETTING, AND PARTICIPANTS: All consecutive blood cultures performed for 6 months during 2020-2021 in 2 hospitals in India were reviewed to assess HOB and National Healthcare Safety Network (NHSN) reportable central-line-associated bloodstream infection (CLABSI) events. Medical records of a convenience sample of 300 consecutive HOB events were retrospectively reviewed to determine source and preventability. Univariate and multivariable logistic regression analyses were performed to identify factors associated with HOB preventability. RESULTS: Among 6,733 blood cultures obtained from 3,558 hospitalized patients, there were 409 and 59 unique HOB and NHSN-reportable CLABSI events, respectively. CLABSIs accounted for 59 (14%) of 409 HOB events. There was a moderate but non-significant correlation (r = 0.51; P = .070) between HOB and CLABSI rates. Among 300 reviewed HOB cases, CLABSIs were identified as source in only 38 (13%). Although 157 (52%) of all 300 HOB cases were potentially preventable, CLABSIs accounted for only 22 (14%) of these 157 preventable HOB events. In multivariable analysis, neutropenia, and sepsis as an indication for blood culture were associated with decreased odds of HOB preventability, whereas hospital stay ≥7 days and presence of a urinary catheter were associated with increased likelihood of preventability. CONCLUSIONS: HOB may have utility as a healthcare-associated infection metric in LMIC settings because it captures preventable bloodstream infections beyond NHSN-reportable CLABSIs.

Unveiling the ESR1 Conformational Stability and Screening Potent Inhibitors for Breast Cancer Treatment

BACKGROUND: The current study recognizes the significance of estrogen receptor alpha (ERα) as a member of the nuclear receptor protein family, which holds a central role in the pathophysiology of breast cancer. ERα serves as a valuable prognostic marker, with its established relevance in predicting disease outcomes and treatment responses. METHOD: In this study, computational methods are utilized to search for suitable drug-like compounds that demonstrate analogous ligand binding kinetics to ERα. RESULTS: Docking-based simulation screened out the top 5 compounds - ZINC13377936, NCI35753, ZINC35465238, ZINC14726791, and NCI663569 against the targeted protein. Further, their dynamics studies reveal that the compounds ZINC13377936 and NCI35753 exhibit the highest binding stability and affinity. CONCLUSION: Anticipating the competitive inhibition of ERα protein expression in breast cancer, we envision that both ZINC13377936 and NCI35753 compounds hold substantial promise as potential therapeutic agents. These candidates warrant thorough consideration for rigorous In vitro and In vivo evaluations within the context of clinical trials. The findings from this current investigation carry significant implications for the advancement of future diagnostic and therapeutic approaches for breast cancer.

Exploring the artificial intelligence and machine learning models in the context of drug design difficulties and future potential for the pharmaceutical sectors.

Artificial intelligence (AI), particularly deep learning as a subcategory of AI, provides opportunities to accelerate and improve the process of discovering and developing new drugs. The use of AI in drug discovery is still in its early stages, but it has the potential to revolutionize the way new drugs are discovered and developed. As AI technology continues to evolve, it is likely that AI will play an even greater role in the future of drug discovery. AI is used to identify new drug targets, design new molecules, and predict the efficacy and safety of potential drugs. The inclusion of AI in drug discovery can screen millions of compounds in a matter of hours, identifying potential drug candidates that would have taken years to find using traditional methods. AI is highly utilized in the pharmaceutical industry by optimizing processes, reducing waste, and ensuring quality control. This review covers much-needed topics, including the different types of machine-learning techniques, their applications in drug discovery, and the challenges and limitations of using machine learning in this field. The state-of-the-art of AI-assisted pharmaceutical discovery is described, covering applications in structure and ligand-based virtual screening, de novo drug creation, prediction of physicochemical and pharmacokinetic properties, drug repurposing, and related topics. Finally, many obstacles and limits of present approaches are outlined, with an eye on potential future avenues for AI-assisted drug discovery and design.

A survey of patient and public perceptions and awareness of SARS-CoV-2-related risks among participants in India and South Africa.

A cross-sectional survey among participants in India and South Africa to explore perceptions and awareness of SARS-CoV-2-related risks. Main outcome measures-proportion of participants aware of SARS-CoV-2, and their perception of infection risks as it related to their views and perceptions on vaccination, i.e., using COVID-19 vaccine uptake as proxy for awareness level. Self-administered questionnaires were used to collect data via web- and paper-based surveys over three months. Pearson's Chi-squared test assessed relationships between variables; a p-value less than 0.05 was considered significant. There were 844 respondents (India: n = 660, South Africa: n = 184; response rate 87.6%), with a 61.1% vs 38.3% female to male ratio. Post-high-school or university education was the lowest qualification reported by most respondents in India (77.3%) and South Africa (79.3%). Sources of pandemic information were usually media and journal publications (73.2%), social media (64.6%), family and friends (47.7%) and government websites (46.2%). Most respondents correctly identified infection prevention measures (such as physical distancing, mask use), with 90.0% reporting improved hand hygiene practices since the pandemic. Hesitancy or refusal to accept the SARS-CoV-2 vaccine was reported among 17.9% and 50.9% of respondents in India and South Africa, respectively; reasons cited included rushed vaccine development and the futility of vaccines for what respondents considered a self-limiting flu-like illness. In South Africa, vaccine acceptance was associated with improved hand hygiene practices since the pandemic and flu vaccination in the preceding year. No relationship was noted between awareness and practice of infection prevention measures (such as hand hygiene) and socio-demographic factors such as employment status or availability of amenities. Pandemic response and infection prevention and control measures through vaccination campaigns should consider robust public engagement and contextually-fit communication strategies with multimodal, participatory online and offline initiatives to address public concerns, specifically towards vaccines developed for this pandemic and general vaccine hesitancy.

Genome analysis of biosurfactant producing bacterium, Bacillus tequilensis.

Bioremediation is crucial for recuperating polluted water and soil. By expanding the surface area of substrates, biosurfactants play a vital role in bioremediation. Biosurfactant-producing microbes release certain biosurfactant compounds, which are promoted for oil spill remediation. In the present investigation, a biosurfactant-producing bacterium Bacillus tequilensis was isolated from Chilika Lake, Odisha, India (latitude and longitude: 19.8450 N 85.4788 E). Whole-Genome Sequencing (WGS) of Bacillus tequilensis was carried out using Illumina NextSeq 500. The size of the whole genome of Bacillus tequilensis was 4.47 MB consisting of 4,478,749 base pairs forming a circular chromosome with 528 scaffolds, 4492 protein-encoding genes (ORFs), 81 tRNA genes, and 114 ribosomal RNA transcription units. The total raw reads were 4209415, and the processed reads were 4058238 with 4492 genes. The whole genome obtained from the present investigation was used for genome annotation, variant calling, variant annotation, and comparative genome analysis with other existing Bacillus species. In this study, a pathway was constructed which describes the biosurfactant metabolism of Bacillus tequilensis. The study identified that genes such as SrfAD, SrfAC, SrfAA and SrfAB are involved in biosurfactant synthesis. The sequence of the genes SrfAD, SrfAC, SrfAA, SrfAB was deposited in GenBank database with accession MUG02427.1, MUG02428.1, MUG02429.1, MUG03515.1 respectively. The whole genome sequence was submitted to GenBank with an accession RMVO00000000 and the raw fastq reads were submitted to SRA, NCBI repository with an accession: SRX5023292.

Review on kidney diseases: types, treatment and potential of stem cell therapy.

Renal disorders are an emerging global public health issue with a higher growth rate despite progress in supportive therapies. In order to find more promising treatments to stimulate renal repair, stem cell-based technology has been proposed as a potentially therapeutic option. The self-renewal and proliferative nature of stem cells raised the hope to fight against various diseases. Similarly, it opens a new path for the treatment and repair of damaged renal cells. This review focuses on the types of renal diseases; acute and chronic kidney disease-their statistical data, and the conventional drugs used for treatment. It includes the possible stem cell therapy mechanisms involved and outcomes recorded so far, the limitations of using these regenerative medicines, and the progressive improvement in stem cell therapy by adopting approaches like PiggyBac, Sleeping Beauty, and the Sendai virus. Specifically, about the paracrine activities of amniotic fluid stem cells, renal stem cells, embryonic stem cells, mesenchymal stem cell, induced pluripotent stem cells as well as other stem cells.

Promoter-motif extraction from co-regulated genes and their relevance to co-expression using E. coli as a model.

Gene expression varies due to the intrinsic stochasticity of transcription or as a reaction to external perturbations that generate cellular mutations. Co-regulation, co-expression and functional similarity of substances have been employed for indoctrinating the process of the transcriptional paradigm. The difficult process of analysing complicated proteomes and biological switches has been made easier by technical improvements, and microarray technology has flourished as a viable platform. Therefore, this research enables Microarray to cluster genes that are co-expressed and co-regulated into specific segments. Copious search algorithms have been employed to ascertain diacritic motifs or a combination of motifs that are performing regular expression, and their relevant information corresponding to the gene patterns is also documented. The associated genes co-expression and relevant cis-elements are further explored by engaging Escherichia coli as a model organism. Various clustering algorithms have also been used to generate classes of genes with similar expression profiles. A promoter database 'EcoPromDB' has been developed by referring RegulonDB database; this promoter database is freely available at www.ecopromdb.eminentbio.com and is divided into two sub-groups, depending upon the results of co-expression and co-regulation analyses.
