Summary: This study developed a new biotin interference-resisting method based on a biotin-streptavidin chemiluminescence immunoassay. By testing streptavidin-coated magnetic microparticles (M) of different concentrations in an automated setting, it was found that higher concentrations of M had a stronger ability to resist biotin interference. The developed method (M3) showed improved ability to resist biotin interference, achieved full automation, and met the general laboratory quality requirements.

Summary: Vitamin D is important for the normal functioning of organs, including the thyroid. Vitamin D deficiency is considered a risk factor for thyroid disorders, but the interaction between vitamin D and thyroid function is not fully understood. Studies comparing vitamin D status with thyroid function and the effect of vitamin D supplementation show inconsistent results, making it difficult to draw a definite conclusion. Additional studies with larger sample sizes are needed to fully understand the effect of vitamin D on thyroid function.

Summary: Thyroid-stimulating hormone (TSH) and thyroid hormone levels are important parameters in blood analysis, but immunoassays used may produce inaccurate results due to interference from certain materials in the sample. Macro-TSH, a complex of TSH with immunoglobulin or albumin, can lead to falsely elevated TSH concentrations. While less well-known, PT-TSH plays a significant role in central regulation of thyroid metabolism.

Summary: False laboratory findings due to biotin supplementation have raised concerns about the safety of immunoassays. Two experiments suggest that biotin interference in laboratory findings is probable, with falsely elevated test results occurring more frequently than falsely low results. Laboratories, medical staff, and patients must be aware of the potential for biotin interference, and further review of interference suppression methods may be necessary for test manufacturers like Roche Diagnostics.

Summary: Immunoassays are important analytical techniques used for qualitative and quantitative analysis. They have been widely implemented in clinical laboratories for the diagnosis, treatment, and prognosis of endocrine disorders. However, interferences in immunoassays can lead to erroneous results and unnecessary procedures, highlighting the need for detection and elimination of these interferences.

Summary: This study systematically reviewed the associations between newborn TSH and childhood neurodevelopment and growth. Findings showed a negative association between newborn TSH and cognitive development in iodine deficient populations, while a null association was found in iodine sufficient populations. Null association was observed between TSH and psychomotor development regardless of iodine status.

Summary: An immunoassay is an effective test method for measuring diagnostic markers, offering high sensitivity, specificity, and automation. However, the biotin-streptavidin system commonly used in immunoassays is susceptible to interference from high levels of supplemental biotin. This review discusses the background, issues, and mitigations related to this interference.

Summary: Thyroid hormones play a critical role in physiological regulation, and this study identifies numerous genetic associations and potential causal genes related to thyroid-stimulating hormone (TSH) levels. The study also develops genetic risk scores for predicting TSH levels and explores the consequences of pathway perturbation.

Summary: This study found that biotin intake can lead to variations in thyroid-related laboratory test results, especially in data measured on the Roche Cobas 6000 and Siemens IMMULITE 2000 platforms. Taking 10 mg of biotin per day can interfere with the measurement results of specific indices such as TSH, fT4, TT3, and Tg.

Summary: The use of antimicrobial growth promoters is banned due to drug residues and increased bacterial resistance. Immunizing chickens with specific antigens to generate antibodies can be an alternative to antibiotics. However, protein impurities and biotin concentrations in IgY antibody samples may affect the accuracy of diagnostic tests.

Summary: By comparing fT4-based screening with TSH-based screening, our study suggests that screening for thyroid dysfunction in older individuals in primary care can be improved by using fT4 or adjusting the TSH cutoff value. This could potentially reduce costs and minimize unnecessary monitoring for patients.

Summary: This study examined the relationship between preoperative TSH levels and the prognosis of DTC by analyzing clinical records of patients at a medical center. Results showed a linear association between preoperative TSH levels and extra-thyroidal extension and lymph node metastasis, while primary tumor size and initial distant metastasis exhibited a bimodal pattern. The study provides insights into the complex relationship between preoperative TSH levels and DTC prognosis.

Summary: Since 2018, Belgium has allowed the incorporation of phages into magistral preparations for human application, emphasizing the importance of stability for quality and efficacy. Through experiments, it was found that DPBS without Ca2+ and Mg2+ was the best option for preserving phage infectivity, while suspensions with phage concentrations of 7 log pfu/mL were not suitable for storage at 4 degrees C.

Summary: The study evaluated the analytical performance of the Elecsys EBV immunoassay panel for detecting EBV viruses, showing good sensitivity and specificity in detecting EBV IgM, VCA IgG, and EBNA IgG. The Elecsys EBV IgM assay demonstrated higher analytical specificity in samples containing potential interferents. Using the Elecsys EBV panel for the EBNA-first approach showed 97.5% overall agreement in samples with clear EBV status.

Summary: Bacterial vaginosis (BV) is a common bacterial vaginal infection with an unknown etiology, characterized by structured polymicrobial biofilms primarily formed by Gardnerella spp. and other anaerobic species. The study compared triple-species biofilms using pre-conditioned and competitive models, finding more significant synergistic growth interactions in the competitive model. Despite model differences, G. vaginalis consistently dominated the biofilm composition, emphasizing its relevance in BV.

Summary: Bacteriophages, viruses that infect bacteria, have been used as antimicrobial agents since the early 20th century. A study found that a novel phage species VA7 has potential antibacterial properties, reducing bacterial counts and IL-8 levels in enterotoxigenic B. fragilis-infected cells, suggesting its use in prophylaxis or treatment of B. fragilis infections and associated colorectal carcinoma.

Summary: This study investigates the potential mechanisms of therapy failure in bacterial vaginosis treatment, revealing that metronidazole and clindamycin face issues of resistance formation and ineffectiveness on biofilm. However, a novel endolysin PM-477 shows high effectiveness in eliminating Gardnerella and has high resilience to resistance formation, making it a promising alternative for the treatment of bacterial vaginosis.
