Summary: This tutorial explains how to conduct a meta-analysis of diagnostic test accuracy studies based on 2x2 tables from primary studies. It discusses univariate methods for analyzing sensitivity and specificity, as well as logistic regression models for sensitivity with and without random effects. The use of diagnostic odds ratios (DOR) to assess publication bias is also covered. Additionally, bivariate random effects models are recommended, along with the construction of summary receiver operating characteristic (sROC) curves using a regression model. The tutorial includes instructions on performing the necessary calculations using the R software and provides an example meta-analysis of studies on Procalcitonin as a diagnostic marker for sepsis.

Summary: The diagnostic accuracy of skin tests and specific IgE quantification in identifying patients reporting a penicillin/B-lactam allergy is low, with low sensitivity and high specificity. More research is needed to assess the role of these tests in stratifying patients for delabeling.

Summary: This study systematically evaluated the accuracy of cholera rapid diagnostic tests (RDTs) and found that they have moderate sensitivity and specificity, especially when enriched with alkaline peptone water (APW). Although they are less useful for clinical management, the current generation of RDTs can be valuable for surveillance efforts if used in a principled manner.

Summary: This study analyzed the accuracy of various diagnostic tests in detecting Burkholderia pseudomallei infection. The results showed that immunofluorescence assay, polymerase chain reaction, and lateral flow immunoassay have moderate sensitivity and specificity. Serological tests have higher sensitivity but lower specificity compared to direct detection methods.

Summary: This paper presents a systematic review and meta-analysis evaluating the reliability of COVID-19 diagnostic tests. Ninety-nine scientific articles were analyzed to assess the specificity and sensitivity of these tests. Molecular tests, such as RT-PCR and CRISPR, performed better in terms of accuracy compared to serological tests. The study highlights the need to improve the performance of these diagnostic tests to effectively control COVID-19 outbreaks.

Summary: This study systematically reviewed the accuracy parameters of different diagnostic methods for detecting SARS-CoV-2, finding that computed tomography has high sensitivity but low specificity, while the combination of IgM and IgG antibodies showed promising results. The research also indicated that RT-PCR remains the gold standard for diagnosing COVID-19 in sputum samples, but combining different diagnostic methods can improve accuracy.

Summary: This study evaluated the accuracy of RNATs in patients with pharyngitis, showing a high sensitivity of 97.5% and specificity of 95.1%. RNATs were found to be more sensitive than RADTs, with equal specificity. The authors suggest that RNATs may be used as stand-alone tests for diagnosing group A streptococcus pharyngitis.

Summary: This study conducted a network meta-analysis to compare the diagnostic accuracies of cerebrospinal fluid and blood biomarkers for sporadic Creutzfeldt-Jakob disease (sCJD) in specialized care settings. The results showed that RT-QuIC and NfL were the most sensitive biomarkers, and RT-QuIC was the most specific biomarker. However, there was high heterogeneity in accuracy estimates between studies.

Summary: This study is the first systematic review to estimate the diagnostic performance of malaria tests on non-invasively collected specimens. PCR-based diagnosis using saliva and urine samples should only be considered when blood samples cannot be collected. The performance of rapid diagnostic testing in urine is limited, especially in terms of sensitivity. Further improvements are needed for malaria testing on non-invasively collected specimens.

Summary: The study aimed to determine the diagnostic accuracy of four blood tests (white cell count (WCC), neutrophil count or percentage, C reactive protein (CRP), and/or procalcitonin) for childhood appendicitis. The results showed that WCC or ANC were the best single blood tests for ruling-out pediatric appendicitis, and the combination of WCC and CRP improved accuracy. These findings have implications for clinical practice.

Summary: This study conducted a systematic review and meta-analysis to assess the association between seasonal influenza vaccination and pneumococcal vaccination with SARS-CoV-2 infection and its clinical outcomes. The results showed that both influenza and pneumococcal vaccination were associated with a lower risk of SARS-CoV-2 infection. However, there was no evidence to support the association between vaccination and harder endpoints such as ICU admission and death.

Summary: This study investigates the development of Computational Thinking (CT) skills in preschool age children by assessing their readiness and exploring the perspectives of parents and preschool teachers. The research findings indicate that preschool children show a high level of readiness for CT activities, although parents express concerns. Additionally, the study reveals that the use of personal computers in kindergarten varies among teachers, with their attitudes towards CT introduction being mainly neutral.

Summary: This article aims to review the evidence generated over the past two decades (2003-2023), identifying the main policy gaps in school health services and health education curricula in Greece and providing a concrete policy plan. The findings suggest that school health services are not school-based but a function of the primary health care system, and health education has a constantly changing position in school curricula. The study also highlights deficiencies in schoolteachers' training, coordination, and leadership. The article provides a set of policy measures towards the reform and integration of school health with health education.

Summary: Diabetes is a risk factor for colorectal cancer, but the mechanisms and genetic variants affecting this relationship are still unclear. Through genome-wide gene-environment interaction analysis, it was found that variations in insulin signaling gene (SLC30A8) and immune function gene (LRCH1) may modify the association between diabetes and colorectal cancer risk.

Summary: The aim of this study was to retrieve the entire spectrum of Kinetoplastea protein sequences containing the PX module, predict their structures, and identify evolutionary conserved and unique traits. A new Kinetoplastea_PX pHMM was constructed using a combination of protein IDs from two searches. The study identified the unique PX-Pkinase domain architecture in Trypanosoma spp. and suggests the potential use of Kinetoplastea PX-proteins as targets for anti-parasitic drug design.

Summary: This study aimed to investigate the effects of stevia leaf extracts or glycosides on oxidative stress markers in diseased rats. The results demonstrated that stevia leaf extracts restored oxidative stress markers to a higher extent compared to pure glycosides. Rats with diabetes mellitus showed the strongest restorative response to stevia leaf extract administration. These findings suggest that stevia leaf extract may have protective effects against various diseases through its antioxidant properties.
