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.

Multi-organ clinical manifestations of Mpox: an umbrella review of systematic reviews.

BACKGROUND: Mpox is a severe viral zoonosis that has emerged as a public health concern due to its potential for human-to-human transmission and severe illness. Understanding its clinical manifestations is crucial for effective management and control. Several systematic reviews have assessed various manifestations of Mpox. This umbrella review synthesizes evidence on Mpox's manifestations across different organ systems. METHOD: We conducted an umbrella review, adhering to Joanna Briggs Institute (JBI) methodology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, focusing on systematic reviews of Mpox manifestations. We performed a literature search up to 25th September 2023, in databases like PubMed, Embase, and Web of Science. We included systematic reviews of observational studies, case reports, case series, or RCTs reporting any manifestations of Mpox in humans, focusing on a global scope. AMSTAR 2 was used to evaluate the quality of systematic reviews, and data has been synthesized in narrative and tabular manners. RESULTS: A total of 25 systematic reviews were included, uncovering diverse manifestations of Mpox, such as cutaneous, cardiovascular, oral, ophthalmic, gastrointestinal, respiratory, and pregnancy-related. Cutaneous manifestations (up to 100%) were the most prevalent, featuring lesions and rashes. Constitutional symptoms of viral illness were reported in ~ 60% to > 85% of the cases. Significant respiratory symptoms were present in ~ 50% of cases overall. Headaches were the leading neurological symptom present in > 30%. Symptoms of gastrointestinal involvement ranged from 39% (oral lesions) with decreasing frequency to low diarrhea at ~ 5%, with proctitis percentages ranging from high teens to mid-twenties. Ophthalmic manifestations (6% but with wide variations among studies). Many primary studies included in the systematic reviews consisted of case reports and case series. A wide range of manifestations across different organ systems was observed. Negative outcomes for pregnancies were reported, but evidence is limited. Adverse cardiovascular and neurological outcomes were identified, though only a few studies provided insights into these findings. CONCLUSION: Mpox exhibits diverse manifestations, impacting multiple organ systems, with substantial variations. The findings highlight the importance of ongoing, nuanced, and region-specific research and management strategies for Mpox. The reliance on case reports and series underscores the need for more high-quality, long-term studies to deepen our understanding and management of this significant public health concern.

Network-Based Drug Repurposing and Genomic Analysis to Unveil Potential Therapeutics for Monkeypox Virus.

The emergence of the human monkeypox virus (MPXV) and the lack of effective medications have necessitated the exploration of various strategies to combat its infection. This study employs a network-based approach to drug discovery, utilizing the BLASTn and phylogenetic analysis to compare the MPXV genome with those of 18 related orthopoxviruses, revealing over 75% genomic similarity. Through a literature review, 160 human-host proteins linked to MPXV and its relatives were identified, leading to the construction of a human-host protein interactome. Analysis of this interactome highlighted 39 central hub proteins, which were then examined for potential drug targets. The process successfully revealed 15 targets already approved for use with medications. Additionally, the functional enrichment analysis provided insights into potential pathways and disorders connected with these targets. Four medications, namely Baricitinib, Infliximab, Adalimumab, and Etanercept, have been identified as potential candidates for repurposing to combat MPXV. In addition, the pharmacophore-based screening identified a molecule that is comparable to Baricitinib and has the potential to be effective against MPXV. The findings of the study suggest that ZINC22060520 is a promising medication for treating MPXV infection and proposes these medications as potential options for additional experimental and clinical assessment in the battle against MPXV.

Adverse pregnancy outcomes in maternal malarial infection: A systematic review and meta-analysis.

Background: Malaria in pregnancy is a critical public health issue that can lead to severe adverse outcomes for both mother and fetus. This systematic review and meta-analysis evaluated the prevalence of adverse birth outcomes in malaria-infected pregnancies and examines their association with the condition. Method: We searched databases up to January 30, 2024, for observational studies on pregnant women with malaria. Data were analyzed using a random-effects model to calculate pooled prevalence rates and risk ratios (RRs) for adverse outcomes, with statistical support from R software version 4.3. Results: Thirty-one studies were included, showing high prevalence of low birth weight (LBW; 17.4 %), preterm birth (17.9 %), and small for gestational age (SGA; 16.1 %) in malaria-affected pregnancies. Infected mothers were significantly more likely to have LBW infants (RR = 1.755), preterm births (RR = 1.484), and SGA infants (RR = 1.554). The risk of stillbirth was not significantly increased (RR = 1.238). Conclusion: Malaria in pregnancy significantly elevates the risk of LBW, preterm birth, and SGA, underscoring the need for effective malaria prevention and treatment strategies in endemic regions. Future research should aim to refine and implement these strategies to enhance maternal and neonatal health outcomes.

Association of cardiovascular disease with severe dengue: A systematic review and meta-analysis.

BACKGROUND: Cardiovascular disease (CVD) and dengue are both significant global health concerns, and their intersection presents a growing clinical challenge. Emerging evidence suggests that individuals with pre-existing CVD may face an elevated risk of severe dengue outcomes. The present study aims to perform a systematic review to assess the relationship between CVD and the severity of dengue. METHODS: We conducted a literature search across multiple databases from inception to November 25, 2023. Primary studies reporting the number of dengue patients with CVD in severe dengue and non-severe dengue groups were included. Quality assessment was performed using the Newcastle-Ottawa Scale, and a meta-analysis was conducted using R software version 4.2 to determine the pooled Relative Risk (RR). The study protocol has been registered in PROSPERO. RESULTS: Based on data from 5 studies involving 274,576 dengue patients, our meta-analysis revealed a significant association between CVD and an increased risk of severe dengue, with a calculated RR of 2.71 (95  % CI: 1.03 to 7.10). However, substantial heterogeneity was observed among the included studies (I2 = 79  %). CONCLUSION: The current evidence suggests an association between CVD and severe dengue, emphasizing the importance of closely monitoring individuals with pre-existing cardiovascular disease and providing them with targeted interventions upon dengue diagnosis to mitigate the risk of severe outcomes.

Incidence and Association of Uveitis with COVID-19 Vaccination: A Systematic Review and Meta-Analysis.

PURPOSE: In the wake of the COVID-19 pandemic, vaccines have been pivotal in curbing disease spread and severity. However, concerns over post-vaccination adverse events, including uveitis, an inflammatory ocular condition, have been noted. This systematic review and meta-analysis aimed to evaluate the incidence and association of uveitis following COVID-19 vaccination. METHODS: A literature search was performed across several databases on October 21, 2023. Human studies examining the incidence of uveitis post-COVID-19 vaccination were included. The Newcastle-Ottawa Scale was used for quality appraisal of the included studies. Meta-analysis was performed to assess the overall incidence of uveitis and the relative risk of developing the condition post-vaccination. All statistical analyses were performed using R software version 4.3. RESULTS: Six studies involving over 2 billion vaccine doses were included. The overall incidence of uveitis was 0.016% (95% CI: 0.010 to 0.026). No significant association was found between vaccination and the onset of uveitis (Relative Risk: 1.45 (95% CI: 0.82 to 2.57, p = 0.12) from four studies. The evidence quality was rated very low due to the limited number of studies and imprecision. CONCLUSION: This analysis indicates a low incidence of uveitis following COVID-19 vaccination and no significant association with the vaccine. The findings are constrained by the small number of studies and low certainty of evidence, underscoring the need for further research. Comprehensive and longitudinal studies are necessary to confirm these findings and reinforce public confidence in COVID-19 vaccination programs.

Prevalence of human papilloma virus among cervical cancer patients in India: A systematic review and meta-analysis.

BACKGROUND: Cervical cancer, predominantly caused by the human papillomavirus (HPV), is a major health challenge in India, with high morbidity and mortality rates. Given India's vast geographic and socio-economic diversity, understanding regional variations in HPV prevalence is crucial for developing targeted and effective public health interventions. This systematic review and meta-analysis were conducted to elucidate the prevalence of HPV among cervical cancer patients in India. METHODS: A literature search was executed across PubMed, EMBASE, and Web of Science up to December 07, 2023. Observational studies reporting HPV prevalence among cervical cancer patients in India are included. A Modified Newcastle-Ottawa scale was used for quality assessment. A random-effects meta-analysis was used to determine pooled HPV prevalence, and heterogeneity was evaluated using the I² statistic. Subgroup and sensitivity analyses were performed to assess result stability and investigate heterogeneity sources. All statistical analyses were performed using R software version 4.3. RESULTS: The meta-analysis included 17 studies with a total of 2529 cervical cancer cases, of which 1977 were HPV-positive. The pooled HPV prevalence was 85% (95% CI: 71-92%), with substantial heterogeneity (I²â€…= 94%). Subgroup analysis by geographic zones showed notable differences: South (88%, 95% CI: 76-95%), North (73%, 95% CI: 1-100%), East (99%, 95% CI: 1-100%), Central (71%, 95% CI: 54-84%), and West (77%, 95% CI: 0-100%). Sensitivity analysis demonstrated the consistency of the results, and a reanalysis, excluding influential studies, yielded a prevalence of 82% (95% CI: 67-91%). CONCLUSION: Our analysis reveals a high prevalence of HPV in cervical cancer patients in India, with significant regional variations. The observed heterogeneity highlights the complexity of HPV epidemiology in India and necessitates further research to explore underlying causes and regional characteristics. Future studies should aim to expand geographic representation and deepen understanding of the factors contributing to the variability in HPV prevalence.

Safety and efficacy of stem cell therapy for Crohn's disease: An umbrella review of systematic reviews.

BACKGROUND: Crohn's disease is a chronic, relapsing form of inflammatory bowel disease marked by severe gastrointestinal inflammation and a broad range of debilitating symptoms. Despite advances in medical treatments, achieving sustained remission remains challenging for many patients. This umbrella review aims to consolidate evidence from various systematic reviews to evaluate the efficacy and safety of stem cell therapies in treating Crohn's disease. METHODS: This review followed the Joanna Briggs Institute methodology and adhered to PRISMA guidelines. A literature search of PubMed, Web of Science, Embase, and the Cochrane Library covered records up to April 20, 2024. Only systematic reviews and meta-analyses on stem cell therapy for Crohn's disease were considered. Data were extracted and analyzed for clinical efficacy indicators like remission induction and safety metrics, including adverse events and mortality rates. RESULTS: Sixteen systematic reviews were included, spanning studies conducted between 2009 and 2023. Stem cell therapy showed a pooled risk ratio (RR) of 1.299 (95% CI: 1.192 to 1.420) for clinical remission, indicating a 29.9% increased likelihood of remission compared to controls. The pooled RR for healing perianal Crohn's disease was 1.358 (95% CI: 1.13 to 1.631), suggesting a 35.8% increased likelihood of healing. A pooled RR of 1.481 (95% CI: 1.036 to 2.116) shows a 48.1% higher immediate fistula closure rate with stem cell therapy. For long-term outcomes, a RR of 1.422 (95% CI: 1.091 to 1.854) indicates a 42.2% increased likelihood of maintaining closure. However, stem cell therapy did not significantly impact Crohn's Disease Activity Index (CDAI) (RR: 1.154, 95% CI: 0.193 to 6.883) and Perianal Disease Activity Index (PDAI) scores (mean difference at 12 weeks: -0.505, 95% CI: -2.481 to 1.471; mean difference at 24 weeks: -0.338, 95% CI: -1.638 to 0.963). The safety profile was comparable to conventional therapies, with a pooled RR of 0.972 (95% CI: 0.739 to 1.278) for adverse events and 1.136 (95% CI: 0.821 to 1.572) for serious adverse events. CONCLUSION: Stem cell therapy offers significant progress in treating Crohn's disease, particularly in complex cases, by improving fistula closure rates and suggesting potential as a supplementary therapy. Its safety profile aligns with conventional treatments, yet ongoing clinical trials are crucial to optimize its use. Continual research will enable healthcare providers to tailor more effective treatment strategies for this challenging condition.

Status of vancomycin-resistant Enterococcus in species of wild birds: A systematic review and meta-analysis.

Wild birds could be a reservoir of medically relevant microorganisms, particularly multidrug-resistant Enterococcus spp. Resistant bacteria's epidemiology and transmission between animals and humans has grown, and their zoonotic potential cannot be ignored. This is the first study to evaluate the status of vancomycin resistant enterococci (VRE) in various wild bird species using meta-analysis and a systematic review. In this study, the pooled prevalence was obtained by analyzing data from published articles on the occurrence of VRE in wild bird species. It's unclear how the antibiotic resistance gene transfer cycle affects wild birds. Google Scholar and PubMed were used to conduct the research. The data and study methodology was assessed and extracted by two reviewers independently, with a third reviewing the results. Heterogeneity between study and publication bias were analyzed using the random effect model. Thirty-eight studies were included in the meta-analysis. 382 out of the 4144 isolates tested, were VRE. The pooled prevalence of VRE among wild birds was estimated at 11.0% (95% CI; 6.9 -17.2%; I2 = 93.204%; P < 0.001). There was high variability between study (t2 = 2.156; heterogeneity I2 = 93.204% with chi-square (Q) = 544.413, degrees of freedom (df) = 37, and P < 0.001). Egger's test verified the funnel plot's bias, while result from the leave-one-out forest plot had no effect on the pooled prevalence.

COVID-19 Vaccine Hesitancy: Umbrella Review of Systematic Reviews and Meta-Analysis.

BACKGROUND: The unprecedented emergence of the COVID-19 pandemic necessitated the development and global distribution of vaccines, making the understanding of global vaccine acceptance and hesitancy crucial to overcoming barriers to vaccination and achieving widespread immunization. OBJECTIVE: This umbrella review synthesizes findings from systematic reviews and meta-analyses to provide insights into global perceptions on COVID-19 vaccine acceptance and hesitancy across diverse populations and regions. METHODS: We conducted a literature search across major databases to identify systematic reviews and meta-analysis that reported COVID-19 vaccine acceptance and hesitancy. The AMSTAR-2 (A Measurement Tool to Assess Systematic Reviews) criteria were used to assess the methodological quality of included systematic reviews. Meta-analysis was performed using STATA 17 with a random effect model. The data synthesis is presented in a table format and via a narrative. RESULTS: Our inclusion criteria were met by 78 meta-analyses published between 2021 and 2023. Our analysis revealed a moderate vaccine acceptance rate of 63% (95% CI 0.60%-0.67%) in the general population, with significant heterogeneity (I2 = 97.59%). Higher acceptance rates were observed among health care workers and individuals with chronic diseases, at 64% (95% CI 0.57%-0.71%) and 69% (95% CI 0.61%-0.76%), respectively. However, lower acceptance was noted among pregnant women, at 48% (95% CI 0.42%-0.53%), and parents consenting for their children, at 61.29% (95% CI 0.56%-0.67%). The pooled vaccine hesitancy rate was 32% (95% CI 0.25%-0.39%) in the general population. The quality assessment revealed 19 high-quality, 38 moderate-quality, 15 low-quality, and 6 critically low-quality meta-analyses. CONCLUSIONS: This review revealed the presence of vaccine hesitancy globally, emphasizing the necessity for population-specific, culturally sensitive interventions and clear, credible information dissemination to foster vaccine acceptance. The observed disparities accentuate the need for continuous research to understand evolving vaccine perceptions and to address the unique concerns and needs of diverse populations, thereby aiding in the formulation of effective and inclusive vaccination strategies.

COVID-19 Vaccine Acceptance and Hesitancy among Migrants, Refugees, and Foreign Workers: A Systematic Review and Meta-Analysis.

Despite the effectiveness of current vaccines in reducing the spread and severity of SARS-CoV-2 infections, many people, including migrants, refugees, and foreign workers, are hesitant to be vaccinated. This systematic review and meta-analysis (SRMA) was conducted to determine the pooled prevalence estimate of the acceptance and hesitancy rates of the COVID-19 vaccine among these populations. A comprehensive search of the peer-reviewed literature indexed in PubMed, Scopus, Science Direct, and Web of Science databases was conducted. Initially, 797 potential records were identified, of which 19 articles met the inclusion criteria. A meta-analysis of proportions using data from 14 studies revealed that the overall acceptance rate of COVID vaccination among 29,152 subjects was 56.7% (95% CI: 44.9-68.5%), while the prevalence of vaccine hesitancy among 26,154 migrants reported in 12 studies was estimated to be 31.7% (95% CI: 44.9-68.5%). The acceptance rate for the COVID-19 vaccination first declined from 77.3% in 2020 to 52.9% in 2021 and then slightly increased to 56.1% in 2022. The most frequent factors influencing vaccine hesitancy were worries about vaccine efficacy and safety. Intensive vaccination campaigns should be implemented to raise vaccination awareness among migrants, which will increase the acceptance rate for the COVID-19 vaccine and result in herd immunity.

An updated review on pathogenic coronaviruses (CoVs) amid the emergence of SARS-CoV-2 variants: A look into the repercussions and possible solutions.

SARS-CoV-2, responsible for COVID-19, shares 79% and 50% of its identity with SARS-CoV-1 and MERS-CoV, respectively. It uses the same main cell attachment and entry receptor as SARS-CoV-1, which is the ACE-2 receptor. However, key residues in the receptor-binding domain of its S-protein seem to give it a stronger affinity for the receptor and a better ability to hide from the host immune system. Like SARS-CoV-1 and MERS-CoV, cytokine storms in critically ill COVID-19 patients cause ARDS, neurological pathology, multiorgan failure, and increased death. Though many issues remain, the global research effort and lessons from SARS-CoV-1 and MERS-CoV are hopeful. The emergence of novel SARS-CoV-2 variants and subvariants raised serious concerns among the scientific community amid the emergence of other viral diseases like monkeypox and Marburg virus, which are major concerns for healthcare settings worldwide. Hence, an updated review on the comparative analysis of various coronaviruses (CoVs) has been developed, which highlights the evolution of CoVs and their repercussions.
