Purpose: Reducing preoperative fasting time showed positive effects in several studies, and current guidelines suggest use of a preoperative oral carbohydrate-rich solution before elective surgeries. For elective colectomy procedures, some surgeons favor two-day bowel preparation with diet restriction and administration of laxatives. Aside from patients experiencing the discomfort of nil per os (NPO), there are reported benefits regarding intake of liquids until at least two hours prior to surgery, including decrease in insulin resistance, without additional postoperative surgical complications. The aim of this study is to show the benefits of administration of oral rehydration solution (ORS) two hours prior to surgery for patients undergoing elective colectomy, particularly postoperative insulin resistance. Methods: This is a randomized controlled trial. All patients undergoing elective colectomy were included and randomized to the control arm or treatment arm. The control arm consisted of the standard bowel preparation and one day of NPO, while the treatment arm consisted of the standard bowel preparation and allowing intake of carbohydrate-rich ORS until 2 hours before surgery. The insulin, glucose, cortisol, and triglyceride levels were determined immediately after induction, 6 hours, 24 hours, and 48 hours post-op, and compared. The homeostatic model assessment-insulin resistance, insulin, glucose, cortisol, and triglyceride levels were determined and compared between the two groups. Anxiety and postoperative complications were monitored and assessed as well. Results: There was less insulin resistance in patients who received ORS 2 hours prior to surgery. Insulin, glucose, cortisol, and triglyceride levels were lower in the treatment group compared to the control group. Taking ORS 1 day prior and until 2 hours before surgery decreased anxiety and discomfort, and alleviated hunger. Conclusion: Regarding complications, there was no difference in the incidence of aspiration and postoperative complications. There were fewer wound complications and incidence of paralytic ileus in the treatment group.

The aim of this study is to build human activity recognition (HAR) model using deep neural network (DNN) and investigate the influence that affects misclassification. As wearable devices become widespread and used in various applications such as health care and sports, people are interested in HAR. Therefore, it is important to improve classification performance in HAR. We implemented a DNN based HAR model through open smartphone sensor data set and t-Distributed Stochastic Neighbor Embedding was used to visualize extracted features. The performance of the DNN model was excellent except for one activity. Through the visualization of the extracted features, we were able to identify the cause of the performance degradation. Similar extracted features between activities are the cause of performance degradation. The DNN model can recognize human activity using smart phone sensor data and be used for health care, sports, fall detection and so on.

Computed tomography (CT) is an important imaging modality in evaluating thoracic malignancies. The clinical utility of dual-energy spectral computed tomography (DESCT) has recently been realized. DESCT allows for virtual monoenergetic or monochromatic imaging, virtual non-contrast or unenhanced imaging, iodine concentration measurement, and effective atomic number (Zeff map). The application of information gained using this technique in the field of thoracic oncology is important, and therefore many studies have been conducted to explore the use of DESCT in the evaluation and management of thoracic malignancies. Here we summarize and review recent DESCT studies on clinical applications related to thoracic oncology.

Landslides pose significant threats to communities and infrastructure, necessitating comprehensive risk assessment for effective mitigation strategies. This abstract presents a novel approach to landslide risk assessment for South Korea, revealing three previously unconsidered factors in the traditional local landslide risk assessment: aspect, elevation, and soil type. Conventional risk assessments have overlooked and have not considered these crucial causative factors, leading to incomplete evaluations. This study uncovers correlations between landslide occurrences and the overlooked variables by integrating data mining and co-occurrence network analysis. The goal is to provide landslide risk evaluators with a more accurate and holistic understanding of landslide risk, facilitating better-informed decision-making. The research highlights the significance of integrating previously neglected factors to enhance the overall effectiveness of landslide risk assessment. The key findings underscore the importance of considering aspect, elevation, and soil type when evaluating landslide risk, enabling stakeholders to anticipate better and address landslide susceptibility in vulnerable regions. This research advances local landslide risk assessment methodologies by shedding light on three essential factors overlooked in traditional approaches. By embracing data mining and network analysis techniques, our findings empower communities and decision-makers with the knowledge needed to develop proactive strategies for mitigating landslide risks and ensuring the safety of vulnerable areas.

Background We previously reported the increase in expression of metallothionein1 (MT1) B, MT1F, MT1G, and MT1H after exposure to polyhexamethylene guanidine phosphate (PHMG-p), a humidifier disinfectant, in human pulmonary alveolar epithelial cells (HPAEpiCs). However, to date, no study has reported the comparative expression of MT1B, MT1F, MT1G, and MT1H in pulmonary cells upon exposure to humidifier disinfectants such as 5-Chloro-2-methyl-3(2H)-isothiazolone with 2-methyl-3(2H)-isothiazolone (CMIT/MIT), oligo(2-(2-ethoxy)ethoxyethyl guanidine chloride) (PGH), benzalkonium chloride (BKC), and sodium dichloroisocyanurate (NaDCC). Objective The present study aimed to evaluate the expression of MT1B, MT1F, MT1G, and MT1H in HPAEpiCs treated with PHMG-p, CMIT/MIT, PGH, BKC, and NaDCC. Results Unlike CMIT/MIT, PGH, BKC, and NaDCC, PHMG-p-treated HPAEpiCs showed increased expression of MT1B, MT1F, MT1G, and MT1H. Similarly, exposure to PHMG and PHMG-HCl also induced the expression of MT1B, MT1F, MT1G, and MT1H. Moreover, polyhexamethylene biguanide hydrochloride, a guanidine structure-based chemical, induced the expression of MT1B, MT1F, MT1G, and MT1H. In contrast, polyhexamethylene diisocyanate hydrochloride and guanidine hydrochloride did not induce MT1B, MT1F, MT1G and MT1H. Conclusion The upregulation of MT1B, MT1F, MT1G, and MT1H in HPAEpiCs is a PHMG-p-specific response in pulmonary cells, and is not induced by CMIT/MIT, PGH, BKC, and NaDCC exposure.
