This study was aimed to evaluate endogenous metabolic changes before and after cisplatin and radiation therapy in patients with cervical cancer via untargeted metabolomic analysis using plasma samples. A total of 13 cervical cancer patients were enrolled in this study. Plasma samples were collected from each patient on two occasions: approximately one week before therapy (P1) and after completion of cisplatin and radiation therapy (P2). Of the 13 patients, 12 patients received both cisplatin and radiation therapy, whereas one patient received radiation therapy alone. The samples were analyzed using the Ultimate 3000 coupled with Q Exactive TM Focus Hybrid Quadrupole-Orbitrap TM mass spectrometry (Thermo Fisher Scientific, Waltham, MA, USA). Chromatographic separation utilized a Kinetex C18 column 2.1×100 mm (2.6 μm) (Phenomenex, Torrance, CA, USA), and the temperature was maintained at 40°C. Following P2, there were statistically significant increases in the concentrations of indoxyl sulfate, phenylacetylglutamine, Lysophosphatidyethanolamine (LysoPE) (18:1), and indole-3-acetic acid compared with the concentrations observed at P1. Specifically, in the human papillomavirus (HPV) noninfection group, indoxyl sulfate, LysoPE (18:1), and phenylacetylglutamine showed statistically significant increases at P2 compared with P1. No significant changes in metabolite concentrations were observed in the HPV infection group. Indoxyl sulfate, LysoPE (18:1), phenylacetylglutamine, and indole-3-acetic acid were significantly increased following cisplatin and radiation therapy.

Purpose: Textbook outcome is a comprehensive measure used to assess surgical quality and is increasingly being recognized as a valuable evaluation tool. Delta-shaped anastomosis (DA), an intracorporeal gastroduodenostomy, is a viable option for minimally invasive distal gastrectomy in patients with gastric cancer. This study aims to evaluate the surgical outcomes and calculate the textbook outcome of DA. Materials and Methods: In this retrospective study, the records of 4,902 patients who underwent minimally invasive distal gastrectomy for DA between 2009 and 2020 were reviewed. The data were categorized into three phases to analyze the trends over time.Surgical outcomes, including the operation time, length of post-operative hospital stay, and complication rates, were assessed, and the textbook outcome was calculated. Results: Among 4,505 patients, the textbook outcome is achieved in 3,736 (82.9%).Post-operative complications affect the textbook outcome the most significantly (91.9%).The highest textbook outcome is achieved in phase 2 (85.0%), which surpasses the rates of in phase 1 (81.7%) and phase 3 (82.3%). The post-operative complication rate within 30 d after surgery is 8.7%, and the rate of major complications exceeding the Clavien–Dindo classification grade 3 is 2.4%. Conclusions Based on the outcomes of a large dataset, DA can be considered safe and feasible for gastric cancer.

Paroxysmal kinesigenic dyskinesia (PKD) is a diagnostic term for transient, involuntary abnormal movements triggered by sudden motions. The treatment for PKD differs from other paroxysmal dyskinesias, as it notably responds well to sodium channel blockers. We report a case of atypical PKD, coupled with paroxysmal exercise-induced dyskinesia (PED). Both PKD and PED in this patient showed a good response to oxcarbazepine. This case could be clinical evidence that paroxysmal dyskinesias could potentially be regarded as a spectrum disorder with overlapping features.

This study aimed to identify metabolic biomarkers and investigate changes in intestinal microbiota in the feces of healthy participants following administration of Lactococcus lactis GEN-001. GEN-001 is a single-strain L. lactis strain isolated from the gut of a healthy human volunteer. The study was conducted as a parallel, randomized, phase 1, open design trial. Twenty healthy Korean males were divided into five groups according to the GEN-001 dosage and dietary control.Groups A, B, C, and D1 received 1, 3, 6, and 9 GEN-001 capsules (1 × 1011 colony forming units), respectively, without dietary adjustment, whereas group D2 received 9 GEN-001 capsules with dietary adjustment. All groups received a single dose. Fecal samples were collected 2 days before GEN-001 administration to 7 days after for untargeted metabolomics and gut microbial metagenomic analyses; blood samples were collected simultaneously for immunogenicity analysis. Levels of phenylalanine, tyrosine, cholic acid, deoxycholic acid, and tryptophan were significantly increased at 5–6 days after GEN-001 administration when compared with predose levels. Compared with predose, the relative abundance (%) of Parabacteroides and Alistipes significantly decreased, whereas that of Lactobacillus and Lactococcus increased; Lactobacillus and tryptophan levels were negatively correlated. A single administration of GEN-001 shifted the gut microbiota in healthy volunteers to a more balanced state as evidenced by an increased abundance of beneficial bacteria, including Lactobacillus, and higher levels of the metabolites that have immunogenic properties.

Some species of Artemisia have been reported to induce apoptosis and autophagy, but little is known of the apoptotic and autophagic effects of the stems and leaves of Artemisia kruhsiana Bess. (AkB). This study was conducted to investigate the antioxidant and anti-autophagic effects of the methanol extracts of the stems (EAkBs) and leaves (EAkBl) of AkB on human prostate cancer PC-3 cells. The antioxidant effects of EAkBs and EAkBl were measured using in vitro total flavonoid and total phenolic assays and a free radical scavenging assay. The effects of EAkBl on cell viability, apoptosis, autophagy, intracellular reactive oxygen species (ROS) generation and protein expression levels were also investigated. EAkBl was found to induce apoptosis, autophagy, and intracellular ROS generation in PC-3 cells. In terms of protein levels, EAkBl reduced phospho (p)-protein kinase B (AKT)/AKT, p-mammalian target of rapamycin (mTOR)/mTOR, B-cell lymphoma 2 (Bcl-2)/Bcl-2-associated X protein (Bax) ratios, and the activations of beclin 1/β-actin and microtubule-associated protein 1A/1B-light chain 3 (LC3) II/LC3 I ratios in PC-3 cells. The results of this study indicate EAkBl has antioxidant and anticancer effects on prostate cancer cells, and that these effects are associated with suppressions of p-AKT, p-mTOR, Bcl-2, and Bax, and the activations of beclin 1 and LC3. Our results indicate EAkBl has potential as a treatment for prostate cancer.

Dracocephalum palmatum Stephan is a medicinal plant traditionally used by nomadic people in Eastern Russia; however, research on this plant is currently limited. Recently, although studies have been conducted on the constituents of this plant and their antioxidant effects, data on its various pharmacological activities are still lacking. Thus, this study examined the anticancer potential of the dried leaves of D. palmatum S. (DpL) using human prostate cancer PC-3 cells. The antioxidant potential of DpL was evaluated by estimating the total flavonoid and total phenolic content (TFC and TPC, respectively). Additionally, we investigated the effects of the DpL ethyl acetate fraction (DpLE) on cell proliferation, intracellular reactive oxygen species (ROS) generation, apoptosis, and cell cycle arrest in this cell line. The expression levels of superoxide dismutase (SOD)-1, SOD-2, B-cell lymphoma 2 (Bcl-2) and Bcl-2 associated X (Bax) ratio, phospho-protein kinase B (p-AKT), cleaved caspase-8, poly adenosine diphosphate (ADP) ribose polymerase (PARP), and cleaved-PARP were evaluated by western blotting. The results indicated that DpLE causes apoptosis and exerts intracellular ROS-independent anticancer effects on prostate cancer cells, associated with increased SOD-2, cleaved caspase-8, and cleaved-PARP expression and inhibited p-AKT signaling. Thus, DpLE may be a potential resource for the development of promising chemotherapeutic agents for prostate cancer.

Purpose: The present study investigated the association between nurse staffing and health outcomes among psychiatric inpatients in Koreaby assessing National Health Insurance claims data. Methods: The dataset included 70,136 patients aged 19 years who were inpatientsin psychiatric wards for at least two days in 2016 and treated for mental and behavioral disorders due to use of alcohol; schizophrenia,schizotypal and delusional disorders; and mood disorders across 453 hospitals. Nurse staffing levels were measured in three ways: registerednurse-to-inpatient ratio, registered nurse-to-adjusted inpatient ratio, and nursing staff-to-adjusted inpatient ratio. Patient outcomesincluded length of stay, readmission within 30 days, psychiatric emergency treatment, use of injected psycholeptics for chemical restraint,and hypnotics use. Relationships between nurse staffing levels and patient outcomes were analyzed considering both patient and systemcharacteristics using multilevel modeling. Results: Multilevel analyses revealed that more inpatients per registered nurse, adjusted inpatientsper registered nurse, and adjusted inpatients per nursing staff were associated with longer lengths of stay as well as a higher risk of readmission.More adjusted inpatients per registered nurse and adjusted inpatients per nursing staff were also associated with increased hypnoticsuse but a lower risk of psychiatric emergency treatment. Nurse staffing levels were not significantly associated with the use of injectedpsycholeptics for chemical restraint. Conclusion Lower nurse staffing levels are associated with negative health outcomes of psychiatricinpatients. Policies for improving nurse staffing toward an optimal level should be enacted to facilitate better outcomes for psychiatricinpatients in Korea.
