Purpose: We investigated whether patients who have been issued a do-not-attempt-resuscitation order (DNAR) preoperatively (hereafter, DNAR patients) are informed of the DNAR code change when they undergo anesthesia. We also conducted a survey of the awareness of medical staff regarding perioperative DNARs, and investigated the current situation at a single-center in Japan.

Methods: For DNAR patients managed by anesthesiologists from January 2019 to September 2022, we retrospectively investigated whether the patient was informed of the DNAR code change or the DNAR was automatically suspended without explanation.

Objective: To investigate the cytological findings of lobular endocervical glandular hyperplasia (LEGH) associated with adenocarcinoma and to clarify its characteristics and the coexisting adenocarcinoma using histochemistry and immunohistochemistry.

Methods: Eighteen surgical cases of LEGH of the uterine cervix were retrospectively reviewed and classified into 3 groups: pure (pure type), atypical (atypical type), and LEGH with adenocarcinoma (mixed type). The mixed type is defined as LEGH or atypical LEGH with in situ or invasive adenocarcinoma.

Objective: We aimed to develop and reinforce a clinical management regimen for atypical endometrial cell (ATEC) categories within the descriptive reporting format for endometrial cytology.

Methods: Between January 2013 and December 2014, 215 samples, for which histological examination was performed immediately or within 3 months after cytology, were cytologically diagnosed as ATEC. For these samples, the medical records were retrospectively reviewed to identify risk factors for malignancy.

Objective: To evaluate the efficacy of the automated screening system FocalPoint for cervical cytology quality control (QC) rescreening. False-negative rates (FNRs) were evaluated by a multi-institutional retrospective study.

Study Design: Cervical cytology slides that had already been reported as negative for intraepithelial lesion or malignancy (NILM) were chosen arbitrarily for FocalPoint rescreening.

The scope of the biomedical laboratory scientist (BLS) differs in the world. The qualification systems for BLS are also different. Even the name of our profession is not standardized, like "BLS", "Medical Technologist (MT) ", "Medical Laboratory Scientist (MLS) ", "Medical Technician", and so on.

The cytological diagnosis of hepatocellular adenoma (HCA) is difficult since it is a very rare tumor and lacks characteristic cytological features. We have just reported a case of inflammatory HCA that displayed an unusual histological pattern (Clin J Gastroenterol 8:426-434, 2015). A touch cytology smear sample was obtained from the surgical specimen, and it also exhibited very unique features.

An industrial microorganism, Streptomyces avermitilis, which is a producer of anthelmintic macrocyclic lactones, avermectins, has been constructed as a versatile model host for heterologous expression of genes encoding secondary metabolite biosynthesis. Twenty of the entire biosynthetic gene clusters for secondary metabolites were successively cloned and introduced into a versatile model host S. avermitilis SUKA17 or 22.

Unlike other synthetic or physiological inhibitors for matrix metalloproteinases (MMPs), the β-amyloid precursor protein-derived inhibitory peptide (APP-IP) having an ISYGNDALMP sequence has a high selectivity toward MMP-2. Our previous study identified amino acid residues of MMP-2 essential for its selective inhibition by APP-IP and demonstrated that the N to C direction of the decapeptide inhibitor relative to the substrate-binding cleft of MMP-2 is opposite that of substrate. However, detailed interactions between the two molecules remained to be clarified.

Purpose: The aim of this study was to compare the cerebral state index (CSI) and bispectral index (BIS) during propofol-fentanyl-nitrous oxide anesthesia.

Methods: Thirty patients scheduled for abdominal surgery, with a mean age of 30-70 years, were enrolled. Anesthesia was induced with propofol and fentanyl and was maintained with propofol, fentanyl, epidural mepivacaine, and nitrous oxide in oxygen.

We report a case of atypical polypoid adenomyoma (APA) concomitantly identified with complex atypical endometrial hyperplasia (CAH) in the uterus. Since an initial endometrial smear revealed atypical endometrial cells, a diagnosis of CAH was made. Even though a concomitantly performed uterine cervical smear contained both atypical epithelial and stromal cells, the diagnosis of APA was not initially made because the cytological criteria for APA had not been established.

Objective: To examine the performance of liquid-based cytology (LBC) in breast cytology to confirm the diagnosis of carcinoma.

Study Design: Using cell clusters directly scratched from surgically removed tumor masses, we examined the immunocytochemistry, molecular biology and cytomorphology of the specimens.

Results: LBC was very useful for gene analysis and evaluating the immunocytochemistry.

The matrix metalloproteinase (MMP) family members catalyze extracellular proteolysis. Recent reports have suggested that expression of MMP-2 and -9 might play a critical role in neoplastic tissue invasion or metastasis. In this study, the relationship between the expression of MMP-2 and -9 and the histological features of tissues from 21 cases of human glioma were investigated.

Purpose: To compare the anesthetic and hemodynamic effects and the predictive factor of anesthesia level of commonly used preparations of hyperbaric bupivacaine and tetracaine in spinal anesthesia.

Methods: Two hundred patients aged 40 to 75 years with ASA physical status I or II were anesthetized spinally via the L4-5 interspace using 0.5% hyperbaric bupivacaine in 7.
