Blood cancers, including leukemia, multiple myeloma, and lymphoma, pose significant challenges owing to their heterogeneous nature and the limitations of traditional treatments. Precision medicine has emerged as a transformative approach that offers tailored therapeutic strategies based on individual patient profiles. Ex vivo drug sensitivity analysis is central to this advancement, which enables testing of patient-derived cancer cells against a panel of therapeutic agents to predict clinical responses. This review provides a comprehensive overview of the latest advancements in ex vivo drug sensitivity analyses and their application in blood cancers. We discuss the development of more comprehensive drug response metrics and the evaluation of drug combinations to identify synergistic interactions.Additionally, we present evaluation of the advanced therapeutics such as antibody–drug conjugates using ex vivo assays. This review describes the critical role of ex vivo drug sensitivity analyses in advancing precision medicine by examining technological innovations and clinical applications. Ultimately, these innovations are paving the way for more effective and individualized treatments, improving patient outcomes, and establishing new standards for the management of blood cancers.

In this study, we show that ANKS1A is specifically expressed in the brain endothelial cells of adult mice. ANKS1A deficiency in adult mice does not affect the differentiation, growth, or patterning of the cerebrovascular system; however, its absence significantly impacts the cerebrovascular system of the aged brain. In aged ANKS1A knock-out (KO) brains, vessel lesions exhibiting cerebral cavernous malformations (CCMs) are observed.In addition, CCM-like lesions show localized peripheral blood leakage into the brain. The CCM-like lesions reveal immune cells infiltrating the parenchyma. The CCM-like lesions also contain significantly fewer astrocyte endfeets and tight junctions, indicating that the integrity of the BBB has been partially compromised. CCM-like lesions display increased fibronectin expression in blood vessels, which is also confirmed in cultured endothelial cells deficient for ANKS1A. Therefore, we hypothesize that ANKS1A may play a role in maintaining or stabilizing healthy blood vessels in the brain during aging.

OBJECTIVES: Dentists and dental hygienists undergo high levels of stress due to various factors and the burnout of health-care personnel is very important in the context of personal and social problems. Therefore, empirical research reflecting the social, cultural, and special circumstances of the medical environment is necessary. Here, we explore the causes and outcomes of burnout in dentists and dental hygienists and present ways to prevent burnout. METHODS: A cross-sectional research design was used to measure burnout of 141 dentists and 61 dental hygienists. A structured questionnaire containing the Maslach Burnout Inventory (MBI) was administered from May to June, 2018. Data were analyzed using SPSS 25.0, descriptive statistics, t-test, Mann-Whitney test, Kruskall-Wallis test, and multiple regression analysis. RESULTS: Each participant's MBI was measured in three aspects (emotional exhaustion, depersonalization, and personal accomplishment). The MBI scores of dentists with regards to their emotional exhaustion, depersonalization, and personal accomplishment were 24.8%, 34%, and 48.2%, respectively. Alternatively the scores of dental hygienists were 45.9%, 44.3% and 52.5%, respectively, for the same parameters. While the factors affecting the burnout of dentists and dental hygienists were different, it had a negative impact on the professional performance of both. CONCLUSIONS: According to the results of this study, Korean dentists and dental hygienists experience high levels of work-related burnouts. This can have adverse impacts on their personal health and that of their patients. Therefore, stress management is necessary in dentists and dental hygienists.

BACKGROUND: We developed a new processing method for extended prostate needle biopsy, and evaluated diagnostic utility of routine immunohistochemistry in 1,000 consecutive unselected cases of transrectal ultrasound-guided systematic prostate biopsy. METHODS: Four to five biopsy cores were embedded in one paraffin block. All the biopsy cores were immunohistochemically stained with basal cell markers. RESULTS: The new sample processing method was technically perfect for making a diagnosis from extended prostate needle biopsy. Among 1,000 cases, there were 323 cases (32.3%) of adenocarcinoma, 5 cases of other malignant tumors, 9 cases of high-grade prostatic intraepithelial neoplasia without a carcinoma, and only 8 cases of atypical small acinar proliferation. Among the 323 cases of adenocarcinoma, there were 38 cases (11.8%) of microcarcinomas <0.1 cm and 101 cases (31.3%) of small adenocarcinomas <0.3 cm in length. In the needle biopsy specimens, 59 cases (18.3%) were classified as clinically insignificant carcinomas. Among them, 37 cases underwent radical prostatectomy, which turned out to be clinically significant carcinomas in 24 cases (64.9%). CONCLUSIONS: Routinely performed immunohistochemistry combined with the new sample processing method is very effective for detecting microscopic carcinoma foci as well as differentiating carcinoma from benign conditions mimicking cancer.
