There continues to be an unrelenting rise in the volumes of laboratory tests ordered in medicine, which is both expensive and has the potential for over-investigation. We performed a quantitative, observational, cross-sectional study of staff with the authority to initiate a laboratory test, using a voluntary, anonymous questionnaire. Our aim was to assess the awareness of and attitudes towards laboratory test costs. 226 surveys were completed over 2 weeks in June, 2012. Most numerous respondents were Staff nurses 125 (55.3%) followed by senior house officers (SHOs) 26 (11.5%) and clinical nurse managers/specialists (CNMs and CNSs) 23 (10.2%). The majority of staff, 191(85.6%), felt unaware of the cost of laboratory tests, which they ordered. For non urgent tests, the majority of respondents, 136 (61.8%) felt cost was either quite of very important. For urgent tests, the majority of respondents, 188 (84.6%) felt cost was of minor or of no importance. Doctors felt more aware of costs than nurses (26.9% vs. 9.3%) and doctors test cost estimates were correct more often than nurses (33% vs. 21%). The results indicate poor awareness of laboratory test cost amongst doctors and nurses. Given the expenditure incurred by a rise in the volume of tests and the potential for over-investigation for patients, strategies for improving the awareness of and attitudes towards laboratory tests need to be developed.

Objectives: To investigate the clinical and laboratory features of Sjögren's syndrome-associated autoimmune liver disease (SS-ALD) patients and identify potential risk and prognostic factors.
Methods: SS patients with or without ALD, who visited Tongji Hospital between the years 2011 and 2021 and met the 2012 American College of Rheumatology (ACR) classification criteria for Sjögren's syndrome, were retrospectively enrolled. The clinical and laboratory data of the enrolled patients, including autoimmune antibodies, were collected and analyzed with principal component analysis, correlation analysis, LASSO regression, and Cox regression.

Introduction Recently, immune cells within the tumor microenvironment (TME) have become crucial in regulating cancer progression and treatment responses. The dynamic interactions between tumors and immune cells are emerging as a promising strategy to activate the host's immune system against various cancers. The development and progression of hepatocellular carcinoma (HCC) involve complex biological processes, with the role of the TME and tumor phenotypes still not fully understood.

This study focuses on the design, synthesis, and evaluation of benzimidazole derivatives for their anti-tumor activity against A549 and PC-3 cells. Initial screening using the MTT assay identified compound 5m as the most potent inhibitor of A549 cells with an IC of 7.19 μM, which was superior to the positive agents 5-Fluorouracil and Gefitinib.

The Childhood Executive Functioning Inventory (CHEXI) is a rating scale that evaluates everyday behaviors associated with executive functions in children. This study aimed to investigate the factor structure and the measurement invariance across parents and teachers of the CHEXI in a sample of 279 Portuguese typically developing children (6 to 12 years old, = 160 girls and = 119 boys). Most studies only analyzed the original two-factor model, and the few that investigated the four-factor model found a nearly identical fit between both factor structures.

Infection with Neisseria gonorrhoeae, the causative agent of gonorrhoea, causes significant morbidity worldwide and can have long-term impacts on reproductive health. The greatest global burden of gonorrhoea occurs in low- and middle-income settings. Global public health significance is increasing due to rising antimicrobial resistance (AMR), which threatens future gonorrhoea management.
