The severity of the disease ranges from mild upper respiratory tract infections to multi-organ failure and disseminated intravascular coagulation. Critical clinical features, such as respiratory failure, myocarditis, acute kidney injury, and a hypercoagulable state, are common in severe COVID-19 illness. Identifying patients at higher risk of rapid disease progression leading to severe complications and death is crucial. Available biomarkers lack specificity and accuracy in identifying the severity of COVID-19 infections. Therefore, there is a need to identify specific endothelial biomarkers that can predict early organ damage, facilitate effective management of patients, and categorise multisystem involvement during COVID-19 infection. Methods The participants constituted laboratory-confirmed COVID-19-positive patients with influenza-like illness (ILI) features under home isolation or moderate to severe acute respiratory infection (SARI) manifestations requiring admission. The chosen markers were analysed using the Human Luminex multiplex bead-based assay system. Results Our study revealed that certain markers, such as intercellular adhesion molecule (ICAM) and Galectin-3 were elevated in all COVID-19-positive patients, while others, like vascular cell adhesion molecule (VCAM), Angiopoietin-2, Thrombomodulin, and tumour necrosis factor receptor 1 (TNFR1) were specifically elevated in patients requiring admission. Such findings indicated the potential of some biomarkers in disease prognostication. Interpretation & conclusions Effective management of COVID-19 requires proper risk stratification.

It is important to monitor residual disease and extend the lead time to detect relapse in high-risk patients. Minimally invasive techniques that utilise circulating biomarkers are being explored for their potential in diagnosis, prognosis, and disease monitoring of breast cancer. Circulating biomarkers have been investigated as tools for breast cancer diagnosis, prognosis, prediction, and monitoring of therapeutic response and resistance. Among these, circulating tumour cells and cell-free plasma DNA (cfDNA) derived from tumour cells (circulating tumour DNA i.e. ctDNA) have been integrated into clinical trial designs. Among all circulating biomarkers, ctDNA stands out as a promising biomaterial with great potential as it is thought to mirror the tumour's evolution. However, its clinical utilisation is hampered mainly by gaps in knowledge of its biological properties and specific characteristics. The development of robust and standardised methods for assessing circulating biomarkers is essential for realising the potential of personalised medicine. This review aims to summarise the characteristics of ctDNA and its role in breast cancer, drawing from both basic and translational research to provide insights into its clinical application. This review suggests that ctDNA has the potential to be a non-invasive, real-time surrogate for tumour tissue-based biomarkers. In conclusion, circulating biomarkers have the potential to revolutionise breast cancer diagnosis, prognosis, and treatment monitoring, but the development of standardised methods for their assessment is essential. ctDNA, in particular, shows great promise as a liquid biopsy tool, but further research is needed to understand its biology and ensure its clinical utility fully.</p>","PeriodicalId":13349,"journal":{"name":"Indian Journal of Medical Research","volume":"161 3","pages":"267-277"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12066141/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144009702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the present study aims to estimate the out-of-pocket payment, catastrophic healthcare expenditures and household wage loss. Methods Field research was conducted with an adapted survey questionnaire. Data from 576 individuals from various healthcare facilities in Punjab were collected using a convenience sampling approach. The out-of-pocket and catastrophic healthcare expenditures (CHE) were estimated using descriptive statistics and indices, viz., headcount overshoot and mean positive overshoot. Lastly, logistic regression models were applied to identify determinants of catastrophic health expenditure.

Further, at any threshold level, the incidence of catastrophic health was highest among diabetic patients. The intensity of catastrophic healthcare expenditure with diabetes and hypertension exceeded the five per cent threshold bracket. Logistic regression results revealed that the odds of incurring catastrophic healthcare expenditure were highest among respondents diagnosed with diabetes, chronic obstructive pulmonary disease (COPD), and stroke.

The objective of this study was to evaluate the prognostic significance of baseline serum ferritin levels in predicting progression-free survival (PFS) and overall survival (OS) in newly diagnosed south Indian patients with multiple myeloma. Methods We retrospectively analysed records of 152 newly diagnosed multiple myeloma (NDMM) patients, grouping them by ferritin levels: group 1 with low ferritin (LF) (<300 ng/ml, n=68) and group 2 with high ferritin (HF) (≥300 ng/ml, n=84). Cox Proportional Hazard Models were used to identify prognostic risk factors for PFS and OS. Results NDMM patients with elevated diagnostic ferritin levels exhibited significantly higher levels of creatinine (P=<0.0001), lactate dehydrogenase (LDH, P=0.005), C-reactive protein (CRP, P=0.02), erythrocyte sedimentation rate (ESR, P=0.04), rate of disease progression (P=0.002), and death (P=0.011), along with a notable decrease in albumin (P=<0.0001) and haemoglobin (P=0.04) compared to MM patients with low ferritin levels.

Vaccines are highly pivotal in promoting an appropriate immune response. Understanding the effectiveness and stability of the vaccines is essential as these may differ across populations. Hence, this study explored the durability and efficacy of the COVISHIELD (ChAdOx1 nCoV-A) vaccine among healthcare workers (HCWs). Methods In this study, 84 HCWs who received two doses of COVISHIELD and had no breakthrough infections or precautionary doses were assessed. Participants were categorised into four groups (A, B, C, and D) based on pre-immunisation antibody status and SARS-CoV-2 RT-PCR results. Group A had prior infection and IgG antibodies, group B had RT-PCR positivity without detectable antibodies, group C had IgG antibodies without RT-PCR testing, and group D was exposure-näive. Humoral immunity was assessed by measuring IgG antibodies to the spike protein, while cell-mediated immunity was evaluated through SARS-CoV-2-specific T-cell markers and immunophenotyping. Results Over one year, a significant decrease in anti-spike IgG levels was observed in all groups (P<0.0001). It was observed that memory B cells declined significantly among all the groups over a period of one year [group A (P<0.0001), group B (P=0.0080), group C (P=0.0158), and group D (P=0.0004)]; no significant decrease inactivated T-cells was observed over a year. The mean of anti-spike IgG levels in samples from exposed participants (group A, B, C) versus non-exposed (group D) was significantly higher (P<0.0001).

Methods We analysed cross-sectional data on 19,902 men who inject drugs, recruited in the 2014/15 Integrated Bio-Behavioural Surveillance study of India's National AIDS Control Organisation. The outcome was human immunodeficiency virus (HIV) status. Syndemic exposures included past-year incarceration, past-year severe physical violence victimisation, and needle/syringe sharing. Regression models included covariates such as age, education, marital status, inconsistent condom use, HIV knowledge, and HIV programme exposure. We tested interactions using linear probability (additive scale) and logistic (multiplicate scale) regression models and examined causal pathways via path analysis. Results In this study, the HIV prevalence was found to be 9.9 per cent among men who inject drugs. We estimated substantial rates of needle/syringe sharing (17.8%), past-year incarceration (10.2%), and severe violence victimisation (3.8%). Among those incarcerated, 28 per cent injected drugs in prison. HIV seropositivity was associated with needle/syringe sharing [Adjusted odds ratio (aOR)=1.33; 95% Confidence interval (CI), 1.08-1.63], but not with violence victimisation or incarceration. In the logistic regression models, a significant two-way interaction was found between needle/syringe sharing and violence victimisation (semi-elasticity=0.65; 95% CI, 0.01-1.29) and a three-way interaction between needle/syringe sharing, violence victimisation, and incarceration (semi-elasticity=1.86; 95% CI, 0.51-3.20). In the linear probability regression models, we estimated a three-way additive interaction (relative excess risk of interaction=0.21; 95% CI, 0.03-0.28). Using path analysis, we estimated statistically significant indirect effects of both incarceration (b=0.02; 95% CI 0.01, 0.03) and severe violence victimisation (b=0.01; 95% CI, 0.008 to 0.02) on the HIV status, operating through their effects on needle/syringe sharing. Interpretation & conclusions Incarceration, violence victimisation, and needle/syringe sharing synergistically interacted to magnify HIV risk among men who inject drugs. These findings suggest the presence of a syndemic. Integrated interventions addressing these co-occurring conditions (e.g., needle/syringe exchange in prisons, violence prevention) may be necessary to effectively reduce HIV transmission among PWID in India.</p>","PeriodicalId":13349,"journal":{"name":"Indian Journal of Medical Research","volume":"161 3","pages":"248-256"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12066131/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143984789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to compare sweat conductivity using Sweat-Chek™ Sweat Analyzer against sweat chloride analysis using the 926 Sherwood chloride analyser and assess if sweat conductivity test can guide CF diagnosis in resource-poor settings. Methods In this retrospective study sweat chloride analysis and sweat conductivity were simultaneously performed on samples collected via Macroduct® system from patients referred for sweat testing. CF diagnosis was based on sweat chloride levels: ≥60 mmol/l confirmed CF, 30-59 mmol/l was borderline, and <30 mmol/l excluded CF. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), and area under curve (AUC) were calculated via ROC curve. Spearman's rho was employed to analyse the correlation between methods. Results Both tests were performed on 118 children of which 106 samples were adequately collected. CF was diagnosed in 11 children. Sweat conductivity ≥ 80 mmol/l diagnosed CF with 100 per cent sensitivity, specificity, PPV, and NPV. Likewise, a value ≤ 49 mmol/l predicted absence of CF with 100 per cent sensitivity, 91.36 per cent specificity, 78.13 per cent PPV, and 100 per cent NPV. Spearman's rho of 0.93 (P< 0.001) showed a strong correlation between the two methods. Intermediate conductivity values also correlated well (rs 0.62, P< 0.003) with intermediate sweat chloride levels. Interpretations & conclusions Sweat conductivity reliably identified CF in the study population including those children with borderline levels, suggesting the possibility of its use in resource-limited settings where sweat chloride analyzers are unavailable.</p>","PeriodicalId":13349,"journal":{"name":"Indian Journal of Medical Research","volume":"161 3","pages":"207-214"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12066134/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144006191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
