Effectiveness of early Anakinra on cardiac function in children with multisystem inflammatory syndrome of COVID-19: a systematic review.

BACKGROUND: Multisystem Inflammatory Syndrome in Children (MIS-C) associated with SARS-CoV-2 can lead to severe cardiovascular complications. Anakinra, an interleukin-1 receptor antagonist, is proposed to benefit the hyperinflammatory state of MIS-C, potentially improving cardiac function. This systematic review evaluated the effectiveness of early Anakinra administration on cardiac outcomes in children with MIS-C. METHODS: A comprehensive search across PubMed, Embase, and Web of Science until March 2024 identified studies using Anakinra to treat MIS-C with reported cardiac outcomes. Observational cohorts and clinical trials were included, with data extraction focusing on cardiac function metrics and inflammatory markers. Study quality was assessed using the Newcastle-Ottawa Scale. RESULTS: Six studies met the inclusion criteria, ranging from retrospective cohorts to prospective clinical studies, predominantly from the USA. Anakinra dosages ranged from 2.3 to 10 mg/kg based on disease severity. Several studies showed significant improvements in left ventricular ejection fraction and reductions in inflammatory markers like C-reactive protein, suggesting Anakinra's role in enhancing cardiac function and mitigating inflammation. However, findings on vasoactive support needs were mixed, and some studies did not report significant changes in acute cardiac support requirements. CONCLUSION: Early Anakinra administration shows potential for improving cardiac function and reducing inflammation in children with MIS-C, particularly those with severe manifestations. However, the existing evidence is limited by the observational nature of most studies and lacks randomized controlled trials (RCTs). Further high-quality RCTs are necessary to conclusively determine Anakinra's effectiveness and optimize its use in MIS-C management for better long-term cardiac outcomes and standardized treatment protocols.

Prevalence of human papillomavirus in head and neck cancer patients in India: a systematic review and meta-analysis.

BACKGROUND: Human papillomavirus (HPV) is increasingly recognized as a significant risk factor in the development of head and neck cancers (HNCs), with varying prevalence and impact. This study aims to systematically review and analyze the prevalence of HPV in HNCs in India, providing insights into regional variations. METHODS: A comprehensive literature search was carried out using PubMed, Embase, and Web of Science up to November 10, 2023. Inclusion criteria focused on original research reporting HPV-positive cases among HNC patients in India. We used Nested-Knowledge software, for screening, and data extraction. The modified Newcastle-Ottawa Scale was used for quality assessment of included studies. We pooled the prevalence of HPV among HNC patients and performed a random-effects model meta-analysis using R software (version 4.3). RESULTS: The search yielded 33 studies, encompassing 4654 HNC patients. The pooled prevalence of HPV infection was found to be 33% (95% CI: 25.8-42.6), with notable heterogeneity (I² = 95%). Analysis of subgroups according to geographical location indicated varying prevalence rates. Specifically, the prevalence was 47% (95% CI: 32.2-62.4) in the eastern regions and 19.8% (95% CI: 10.8-33.4) in the western regions. No evidence of publication bias was detected. CONCLUSION: The observed considerable regional disparities on the prevalence of HPV in HNC patients in India emphasizes the need for integrated HPV vaccination and screening programs in public health strategies. The findings underline the necessity for further research to explore regional variations and treatment responses in HPV-associated HNCs, considering the impact of factors such as tobacco use and the potential benefits of HPV vaccination.

Adverse cardiovascular outcomes associated with proton pump inhibitor use after percutaneous coronary intervention: a systematic review and meta-analysis.

BACKGROUND: Proton pump inhibitors (PPIs) are commonly prescribed for gastroprotection in patients undergoing percutaneous coronary intervention (PCI), who are at increased risk of gastrointestinal bleeding due to antiplatelet therapy. However, emerging evidence suggests that PPIs may adversely impact cardiovascular outcomes. This systematic review and meta-analysis sought to assess the relationship between using PPIs and cardiovascular outcomes in patients following PCI. METHODS: We searched various databases up to March 15, 2024, for observational studies and randomized controlled trials (RCTs) assessing the cardiovascular effects of PPIs in PCI patients. Data were extracted on study characteristics, patient demographics, PPI use, and cardiovascular outcomes. The Newcastle-Ottawa Scale and Cochrane Risk of Bias Tool 2 assessed study quality. Meta-analyses were conducted using a random-effects model using R software version 4.3. RESULTS: A total of 21 studies involving diverse populations and study designs were included. Observational studies suggested a moderate increase in risk for composite cardiovascular diseases (CVD), myocardial infarction (MI), and major adverse cardiac events (MACE) associated with PPI use, with pooled hazard ratios (HRs) of 1.20 (95% CI: 1.093-1.308) for CVD, 1.186 (95% CI: 1.069-1.303) for MI, and 1.155 (95% CI: 1.001-1.309) for MACE. However, RCTs showed no significant link between PPI therapy and negative cardiovascular events (Relative Risk: 1.016, 95% CI: 0.878-1.175). Substantial heterogeneity was observed among observational studies but not RCTs. CONCLUSION: The findings indicate that while observational studies suggest a potential risk of adverse cardiovascular events with post-PCI use of PPI, RCTs do not support this association. Further large-scale, high-quality studies are required to understand the cardiovascular implications of individual PPIs better and optimize patient management post-PCI. This analysis shows the complexity of PPI use in patients with coronary artery diseases and the necessity to balance gastroprotective benefits against potential cardiovascular risks.

Smokeless tobacco consumption among women of reproductive age: a systematic review and meta-analysis.

Smokeless tobacco (SLT) poses many negative health impacts. Despite its longstanding presence in societies across the world, the health implications of SLT have only been rigorously studied in recent decades. This systematic review and meta-analysis aimed to consolidate existing research to provide a comprehensive understanding of the global prevalence of SLT use among women of reproductive age. Relevant articles were extracted from databases such as PubMed, EMBASE, Web of Science, and Scopus from their inception until November 11, 2023. Observational studies reporting the number of SLT users among women of reproductive age were included. The quality of the studies was assessed using the Joanna Briggs Institute (JBI) tool. The meta-analysis used a random-effects model to determine SLT prevalence, supported by statistical tools like forest plots, I2 statistics, and sensitivity analyses to ensure the accuracy and comprehensiveness of the results. All statistical analyses were performed in R version 4.3. From 10 studies involving 2,053,667 participants, a pooled prevalence for SLT use among women of reproductive age was found to be 9.3% (95% CI: 0.038 to 0.21), with significant heterogeneity among studies (I2 = 100%). Publication bias was suspected among the studies. Sensitivity analysis and subgroup analysis couldn't resolve the heterogeneity. Our analysis shows a significant prevalence of SLT use in women of reproductive age, especially in low socioeconomic and developing countries like India, Pakistan, and Nepal. For women of reproductive age, the use of smokeless tobacco (SLT) can lead to infertility, pregnancy complications, and adverse fetal outcomes, including low birth weight and preterm birth. The results highlight the necessity for specific public health measures and policy changes to decrease SLT consumption among reproductive-age women. Further studies are needed to investigate the reasons behind SLT usage in this group and to assess the impact of intervention strategies, to guide more effective public health initiatives and policies.

A Comprehensive Review on the Electrocardiographic Manifestations of Cardiac Sarcoidosis: Patterns and Prognosis.

PURPOSE OF REVIEW: Cardiac sarcoidosis (CS) refers to cardiac involvement in sarcoidosis and is usually associated with worse outcomes. This comprehensive review aims to elucidate the electrocardiographic (ECG) signs and features associated with CS, as well as examine modern techniques and their importance in CS evaluation. RECENT FINDINGS: The exact pathogenesis of CS is still unclear, but it stems from an abnormal immunological response triggered by environmental factors in individuals with genetic predisposition. CS presents with non-cardiac symptoms; however, conduction system abnormalities are common in patients with CS. The most common electrocardiographic (ECG) signs include atrioventricular blocks and ventricular tachyarrhythmia. Distinct patterns, such as fragmented QRS complexes, T-wave alternans, and bundle branch blocks, are critical indicators of myocardial involvement. The application of advanced ECG techniques such as signal-averaged ECG, Holter monitoring, wavelet-transformed ECG, microvolt T-wave alternans, and artificial intelligence-supported analysis holds promising outcomes for opportune detection and monitoring of CS. Timely utilisation of inexpensive and readily available ECG possesses the potential to allow early detection and intervention for CS. The integration of artificial intelligence models into ECG analysis is a promising approach for improving the ECG diagnostic accuracy and further risk stratification of patients with CS.

This systematic review and meta-analysis aimed to synthesize available evidence on the association between PTSD and various cardiovascular outcomes. METHODS: We conducted a comprehensive literature search in databases until March 15, 2024. Studies were included if they were observational in design and assessed the association between PTSD and cardiovascular outcomes. Data were extracted on study characteristics, participant demographics, PTSD assessment, cardiovascular outcomes, and effect estimates. Meta-analyses were performed using random-effects models, and heterogeneity was assessed using the I² statistic. All statistical analyses were conducted using R software version 4.3. RESULTS: Twenty studies met the inclusion criteria, encompassing a total of over 335,000 participants. The pooled analyses demonstrated a statistically significant increased risk of any CVD (HR = 1.417, 95 % CI: 1.313-1.522), MI (HR = 1.415, 95 % CI: 1.331-1.500), and stroke (HR = 2.074, 95 % CI: 1.165-2.982) associated with PTSD. Substantial heterogeneity was observed across the studies for stroke and MACE, and evidence of publication bias was noted. CONCLUSION: This meta-analysis confirms a significant association between PTSD and an increased risk of several cardiovascular outcomes, indicating the importance of integrating cardiovascular risk management with psychiatric care for PTSD patients to mitigate the heightened risk of CVDs. Future research should focus on exploring the underlying mechanisms and potential interventions to manage both PTSD and its associated cardiovascular risks effectively.

Global outbreaks of foodborne hepatitis A: Systematic review and meta-analysis.

Hepatitis A Virus (HAV) is a significant threat in terms of food safety. A systematic literature search with the research question "What are the clinical outcomes of foodborne Hepatitis A virus infections?" was conducted. The pooled estimate of the outcomes-mortality, hospitalization, and severity rates, along with a 95% confidence interval (CI), was estimated. After screening, 33 studies were included for the data extraction and meta-analysis. The pooled prevalence of hospitalization among the HAV-positive patients was estimated to be 32% (95% CI 21-44), with high heterogeneity (I2 = 98%, p < 0.01). Australia had the highest hospitalization rate, with 82%, followed by Europe (42%). The hospitalization rate showed a significantly increasing trend (beta = 0.015, p=0.002) over the period. The pooled prevalence of mortality among the HAV-positive patients was estimated to be <1%, with low heterogeneity (I2 = 5%, p = 0.39). A wide range of food products were linked with the HAV outbreaks.

Association of neighborhood deprivation and hypertension: A systematic review and meta-analysis.

Effect of Intravenous Mannitol on Intraocular Pressure Changes in Vitrectomized and Non-Vitrectomized Eyes: A Systematic Review and Meta-Analysis.

PURPOSE: Intraocular pressure (IOP) control is paramount during ophthalmic surgeries to ensure successful outcomes and prevent complications. Intravenous mannitol has been explored for its ability to manage IOP fluctuations in both vitrectomized and non-vitrectomized eyes. This meta-analysis aimed to assess the efficacy of mannitol in controlling IOP across these patient groups. DESIGN: Systematic review and meta-analysis. METHODS: A literature search was conducted across PubMed, EMBASE, Scopus, and Web of Science from inception up to March 1, 2024, focusing on studies investigating mannitol's impact on IOP in vitrectomized and non-vitrectomized eyes. Randomized controlled trials, cohort studies, and case-control studies were included, while case reports and review articles were excluded. The primary outcome was the change in IOP following mannitol administration. Meta-analysis was performed using a random-effects model. R software (V 4.3) was used for statistical analysis. RESULTS: Our search included five studies of both vitrectomized (145 eyes) and non-vitrectomized eyes (91 eyes). The meta-analysis demonstrated significant IOP reductions following mannitol administration across multiple time points. Three studies were included at 30 min and 2 studies at all other time points in the analysis. In vitrectomized eyes, notable decreases were observed: at 30 min, the Ratio of Means (ROM) was 0.81 (95% CI: 0.53; 1.24), indicating a 19% reduction; at 60 min, the ROM of 0.833 (95% CI: 0.77; 0.89) showed a 16.7% reduction; at 90 min, the ROM of 0.757 (95% CI: 0.755; 0.758) corresponded to a 24.3% reduction; at 2 h, the ROM of 0.726 (95% CI: 0.642; 0.820) reflected a 27.4% reduction; at 3 h, the ROM of 0.692 (95% CI: 0.600; 0.797) resulted in a 30.8% reduction; and at 4 h, the ROM of 0.700 (95% CI: 0.363; 1.350) indicated a 30% reduction. No significant changes were observed on IOP with mannitol administration when comparing vitrectomized versus non- vitrectomized eyes. CONCLUSION: Intravenous mannitol effectively reduces IOP in both vitrectomized and non-vitrectomized eyes, demonstrating its utility in the acute management of elevated IOP during and after ophthalmic surgeries. These findings support the integration of mannitol into perioperative care protocols. However, further research, particularly randomized controlled trials and studies with broader demographic representation, is needed to optimize mannitol's usage and fully understand its long-term safety and efficacy.

Redefining Management in Hypertrophic Cardiomyopathy: The Role and Challenges of Exercise Rehabilitation.

Hypertrophic cardiomyopathy (HCM), a common genetic heart condition, is characterized by thickening of the left ventricle, which can result in a range of health issues, such as arrhythmias, heart failure, and sudden death. Despite traditional cautions against exercise in HCM patients due to potential exacerbation of symptoms and risk of sudden death, recent evidence suggests a paradigm shift toward the benefits of structured exercise rehabilitation. The pathogenesis of HCM, the physical and psychological effects of the illness on patients, and changing views on exercise as a therapeutic intervention are all covered in this review. Recent research shows that modest physical activity can considerably enhance functional ability, psychological health, and overall quality of life in individuals with heart failure without increasing the risk of unfavorable cardiac events, challenging earlier recommendations. Moreover, exercise rehabilitation has been shown to induce favorable myocardial remodeling and enhance cardiovascular fitness, suggesting a revaluation of exercise prescriptions tailored to individual patient profiles. Despite the promising role of exercise in managing HCM, this review also acknowledges the complexities of implementing rehabilitation programs, including the need for comprehensive patient assessment, personalized exercise regimens, and monitoring for potential complications. Future research should focus on optimizing exercise recommendations, understanding long-term outcomes, and integrating exercise rehabilitation into standard care protocols for HCM to foster a more holistic approach to patient management. Underscoring the necessity of a multidisciplinary strategy that balances the benefits of physical activity with the unique risks associated with HCM with the aim of improving patient outcomes through evidence-based, patient-centered care.

Association of Child Growth Failure Indicators With Household Sanitation Practices in India (1998-2021): Spatiotemporal Observational Study.

BACKGROUND: Undernutrition among children younger than 5 years is a subtle indicator of a country's health and economic status. Despite substantial macroeconomic progress in India, undernutrition remains a significant burden with geographical variations, compounded by poor access to water, sanitation, and hygiene services. OBJECTIVE: This study aimed to explore the spatial trends of child growth failure (CGF) indicators and their association with household sanitation practices in India. METHODS: We used data from the Indian Demographic and Health Surveys spanning 1998-2021. District-level CGF indicators (stunting, wasting, and underweight) were cross-referenced with sanitation and sociodemographic characteristics. Global Moran I and Local Indicator of Spatial Association were used to detect spatial clustering of the indicators. Spatial regression models were used to evaluate the significant determinants of CGF indicators. RESULTS: Our study showed a decreasing trend in stunting (44.9%-38.4%) and underweight (46.7%-35.7%) but an increasing prevalence of wasting (15.7%-21.0%) over 15 years. The positive values of Moran I between 1998 and 2021 indicate the presence of spatial autocorrelation. Geographic clustering was consistently observed in the states of Madhya Pradesh, Jharkhand, Odisha, Uttar Pradesh, Chhattisgarh, West Bengal, Rajasthan, Bihar, and Gujarat. Improved sanitation facilities, a higher wealth index, and advanced maternal education status showed a significant association in reducing stunting. Relative risk maps identified hotspots of CGF health outcomes, which could be targeted for future interventions. CONCLUSIONS: Despite numerous policies and programs, malnutrition remains a concern. Its multifaceted causes demand coordinated and sustained interventions that go above and beyond the usual. Identifying hotspot locations will aid in developing control methods for achieving objectives in target areas.

Association between homocysteine and coronary artery disease-trend over time and across the regions: a systematic review and meta-analysis.

BACKGROUND: The association of homocysteine with coronary artery disease (CAD) has been explored previously with mixed findings. The present Systematic Review and Meta-Analysis (SRMA) has assessed the pooled estimate of association between homocysteine (Hcy) and CAD, and its variation over the period and geography. METHODS: Systematic literature search was done in PubMed, Scopus and Cochrane to identify the observational studies that have reported mean Hcy among cases (CAD) and control. The SRMA was registered in PROSPERO (ID-CRD42023387675). RESULTS: Pooled standardized mean difference (SMD) of Hcy levels between the cases and controls was 0.73 (95% CI 0.55-0.91) from 59 studies. Heterogeneity was high (I2 94%). The highest SMD was found among the Asian studies (0.85 [95% CI 0.60-1.10]), while the European studies reported the lowest SMD between the cases and controls (0.32 [95% CI 0.18-0.46]). Meta-regression revealed that the strength of association was increasing over the years (Beta = 0.0227, p = 0.048). CONCLUSIONS: Higher homocysteine levels might have a significant association with coronary artery diseases, but the certainty of evidence was rated low, owing to the observational nature of the studies, high heterogeneity, and publication bias. Within the population groups, Asian and African populations showed a greater strength of association than their European and American counterparts, and it also increased over the years.

Performance of ChatGPT on the India Undergraduate Community Medicine Examination: Cross-Sectional Study.

BACKGROUND: Medical students may increasingly use large language models (LLMs) in their learning. ChatGPT is an LLM at the forefront of this new development in medical education with the capacity to respond to multidisciplinary questions. OBJECTIVE: The aim of this study was to evaluate the ability of ChatGPT 3.5 to complete the Indian undergraduate medical examination in the subject of community medicine. We further compared ChatGPT scores with the scores obtained by the students. METHODS: The study was conducted at a publicly funded medical college in Hyderabad, India. The study was based on the internal assessment examination conducted in January 2023 for students in the Bachelor of Medicine and Bachelor of Surgery Final Year-Part I program; the examination of focus included 40 questions (divided between two papers) from the community medicine subject syllabus. Each paper had three sections with different weightage of marks for each section: section one had two long essay-type questions worth 15 marks each, section two had 8 short essay-type questions worth 5 marks each, and section three had 10 short-answer questions worth 3 marks each. The same questions were administered as prompts to ChatGPT 3.5 and the responses were recorded. Apart from scoring ChatGPT responses, two independent evaluators explored the responses to each question to further analyze their quality with regard to three subdomains: relevancy, coherence, and completeness. Each question was scored in these subdomains on a Likert scale of 1-5. The average of the two evaluators was taken as the subdomain score of the question. The proportion of questions with a score 50% of the maximum score (5) in each subdomain was calculated. RESULTS: ChatGPT 3.5 scored 72.3% on paper 1 and 61% on paper 2. The mean score of the 94 students was 43% on paper 1 and 45% on paper 2. The responses of ChatGPT 3.5 were also rated to be satisfactorily relevant, coherent, and complete for most of the questions (>80%). CONCLUSIONS: ChatGPT 3.5 appears to have substantial and sufficient knowledge to understand and answer the Indian medical undergraduate examination in the subject of community medicine. ChatGPT may be introduced to students to enable the self-directed learning of community medicine in pilot mode. However, faculty oversight will be required as ChatGPT is still in the initial stages of development, and thus its potential and reliability of medical content from the Indian context need to be further explored comprehensively.

METHODS: A literature search was performed across multiple databases up to February 12, 2024, to identify studies evaluating the risk of corneal transplant rejection post-COVID-19 vaccination. Eligible studies were original research that reported outcomes of corneal graft rejection following vaccination. Nested Knowledge web software facilitated screening and data extraction. The Newcastle-Ottawa Scale was employed for quality assessment. A meta-analysis was conducted to calculate the aggregated relative risk (RR) utilizing R software version 4.3. RESULTS: Six studies were included in the qualitative synthesis, with four meeting the criteria for meta-analysis. These studies varied in geographic location, surgical techniques, and types of vaccines used. The pooled RR for corneal transplant rejection following COVID-19 vaccination was 0.816 (95% CI 0.178-1.453), indicating no significant risk of rejection. No statistical heterogeneity was observed among the studies (I2 = 0%). CONCLUSIONS: This review and meta-analysis found no significant evidence that COVID-19 vaccination increases the risk of corneal graft rejection. However, the current evidence is insufficient to conclusively determine the vaccine's safety for corneal transplant recipients. These findings underscore the need for additional research to confirm these preliminary results and investigate the long-term effects of COVID-19 vaccination on corneal transplants, aiming to provide evidence-based guidance to healthcare providers and patients.

Inequalities in cardiovascular disease among elderly Indians: A gender perspective analysis using LASI wave-I (2017-18).

BACKGROUND: While Cardiovascular disease (CVD) affects both men and women, emerging evidence suggests notable gender differentials in disease prevalence. This study aims to explore and analyse the gender differentials in CVD disease prevalence in India. METHODS: The present study utilizes data from first wave of the nationally representative survey "Longitudinal Ageing Study in India" (LASI, WAVE-I, 2017-18) with the eligible sample size of 31,464 individuals aged 60 years and above. Logistic regression analysis was used to understand risk of CVD by demographic characteristics. Factors contribution to gender differences in CVD prevalence was examined using a non-linear Fairlie decomposition. RESULTS: The prevalence of CVD was lower in men (31.06%) compared to women (38.85%). Women have a 33% higher likelihood of CVD compared to men (OR: 1.33; 95% CI: 1.25-1.42). Lack of education also confers a lower risk, more pronounced in women with no schooling (OR: 0.81; 95% CI: 0.7-0.94) compared to men (OR: 0.52; 95% CI: 0.47-0.58). Morbidity influences CVD presence more among women than men, with individuals suffering from three or more diseases having markedly increased odds (Men: OR: 3.89; 95% CI: 3.54-4.3, Women: OR: 6.97; 95% CI: 6.48-10.11). Smoking accounted increase in (20.52%) the gender gap while years of schooling dramatically lessened the gender gap (-46.30%). CONCLUSION: Result show gender differential in CVD prevalence and underlying risk factors, underscoring the need for gender-specific preventive strategies and interventions. Our findings highlight the importance of refined approach to cardiovascular health that considers the complex interplay of biological, social, and environmental determinants.
