Summary: The study aimed to evaluate and compare the diagnostic efficacy of metagenomic NGS (mNGS) for bacterial meningoencephalitis (BM/E) diagnosis. The analysis showed that mNGS had moderate diagnostic accuracy in diagnosing BM/E from cerebrospinal fluid specimens, and it can be particularly helpful in cases with undiagnosed BM/E.

Summary: The poor survival of triple-negative breast cancer (TNBC) is attributed to its aggressive behavior, large heterogeneity, and high risk of recurrence. Next-generation sequencing (NGS) has been used to investigate the molecular characteristics of TNBC, revealing recurrent pathogenic alterations in TP53, immunocheckpoint response genes, and PIK3CA and DNA repair pathways. NGS has also identified potential personalized treatments and novel biomarkers such as AURKA, MYC, and JARID2 mutations. Additionally, NGS studies have identified ethnicity-specific alterations in African and African American TNBC, including EZH2 overexpression, BRCA1 alterations, and a BRCA2-delaAAGA mutation. The development of long-read sequencing methods and their combination with optimized short-read techniques hold promise for improving the efficiency of NGS approaches in future clinical use.

Summary: This study evaluated the diagnostic accuracy of metagenomic next-generation sequencing (mNGS) and GeneXpert Mycobacterium tuberculosis (MTB) for identifying tuberculous pleurisy and analyzing the microbial profiles of both tuberculous and non-tuberculous pleural effusions. The results showed that both tests had high specificity and positive predictive value for detecting tuberculous pleurisy, along with comparable sensitivity. Additionally, mNGS analysis revealed valuable insights into the microbial profiles of both types of pleural effusions.

Summary: This study evaluated the performance of four rapid diagnostic tests (RDTs) for Ebola virus disease (EVD) detection. The sensitivity of the RDTs did not meet the desired levels set by the World Health Organization, but the specificity was satisfactory. Among the RDTs evaluated, QuickNavi-EbolaTM and OraQuick(R) Ebola Rapid Antigen Test showed the most favorable profiles and can be used as frontline tests for screening suspected cases.

Summary: This study demonstrates the use of a targeted HPV next generation sequencing (NGS) panel for cervical cancer screening. The targeted panel shows similar sensitivity and specificity to commercial HPV assays, but also provides additional advantages such as specific detection of all relevant HPV types and identification of viral integration and variants.

Summary: The study demonstrates that RT-LAMP has a diagnostic accuracy comparable to RT-qPCR in the early phase of COVID-19, until the 9th day after symptom onset. However, after the 10th day, the positivity rate of RT-LAMP significantly decreases, suggesting its limitations in diagnosing COVID-19 in later stages of the disease.

Summary: This article proposes a novel Bayesian approach to determine the sample size for the diagnostic accuracy study, utilizing information from the analytical validity stage. The approach uses assurance to calculate the required sample size based on the target width of a posterior probability interval and allows for the choice of using or disregarding the data from the analytical validity study. Sensitivity analyses and evaluations of prior-data conflict are performed to assess the robustness of the proposed method. The results demonstrate that the assurance-based approach can reduce the required sample size when suitable prior information is available.

Summary: The study found that mNGS had a higher sensitivity than the traditional method, especially in blood, bronchoalveolar lavage fluid and sputum samples. The positive mNGS group had a higher hospital stay and 28-day mortality, with age being significant in multivariate logistic analyses of positive results of mNGS.

Summary: Given the lack of accurate rapid diagnostics for UTI in women, guidelines have been developed to support appropriate antibiotic prescribing, but some guidelines have not been validated. A study was conducted to validate the diagnostic accuracy of two guidelines: Public Health England (GW-1263) and Scottish Intercollegiate Guidelines Network (SIGN160). The results demonstrate the potential for diagnostic error when using these guidelines for managing uncomplicated UTI and making antimicrobial prescribing decisions.

Summary: In this study, the evolution trajectories of ALS patients were investigated using Process Mining techniques, revealing differences in disease progression based on patients' characteristics. The study found that most patients start without impairments, and impairment of Walking/Self-care abilities is the most common initial symptom. Spinal onset increases the risk of experiencing the loss of Walking/Self-care ability as the first impairment, and older age at onset corresponds to a faster progression to death. The comparison between the trial population and the clinical cohort showed similarities in the natural progression of the disease, but differences in observed trajectories potentially due to trial scheduling and recruitment criteria.

Summary: Protein turnover rate is crucial for cellular functions and dysregulation of protein degradation can lead to various diseases. Studying protein synthesis and degradation rates is important to understand the pathophysiology of diseases. This study used a dynamic-SILAC approach to investigate protein turnover and abundance in a cellular model of diabetic nephropathy, identifying several proteins with altered turnover and abundance between diabetic nephropathic subjects and controls. These proteins could potentially serve as biomarkers or therapeutic targets for diabetic complications. The data obtained also provide valuable information on protein half-lives in human fibroblasts and contribute to basic cell biology.

Summary: Predicting protein function is a major challenge, and traditional methods can be resource-intensive and time-consuming. Automated protein function prediction techniques, especially those using machine learning, have shown promise in providing faster and cost-effective alternatives. Recent research has focused on improving prediction accuracy using machine learning, with the goal of closing the gap between predicted and experimental evidence.

Summary: This study evaluated the sex differences in the immune microenvironment of rectal cancer patients and found that male patients had more frequent oncogene mutations associated with lower expression of T-cell activation genes, while female patients had more Th1 cells and cytotoxic T cells in the healthy mucosa, suggesting a potentially better immune response to the tumor.

Summary: This study aimed to investigate the causes of continuous deep fluctuations in ALC in an untreated CLL patient who has had a favorable prognosis since diagnosis. The patient has chosen to adopt a vegetarian and fruitarian diet, along with prolonged fasting. Transcriptome profiling analysis revealed nine differentially expressed genes between the patient and other untreated CLL patients, providing potential insights into the role of fasting and gene expression in sustaining the lymphocytosis trend.

Summary: Fecal microbiota transplantation (FMT) is a promising approach for decreasing disease activity in canine chronic enteropathies (CE), but the relationship between remission mechanisms and microbiome changes is not yet elucidated. This study aimed to report the clinical effects of oral freeze-dried FMT in CE dogs by comparing the fecal microbiomes of pre-FMT CE-affected dogs, post-FMT dogs, and healthy dogs. Diversity analysis, differential abundance analysis, and machine learning algorithms were applied to investigate the differences in microbiome composition. Clinical improvement was observed in 74% of CE-affected dogs, with a significant decrease in Disease Activity Index. Each receiver showed variations in microbiome composition after FMT, indicating the need for further research on different healing patterns of microbiome changes.
