Published: January 2022

Abstract
A new model, integrating information theory, fractal theory and statistical model for accurate landslide susceptibility mapping (LSM) at regional scales, has been proposed. In this model, landslide conditional factors are firstly classified with an optimal number of classes, which is determined by maximizing their information coefficients estimated from Shannon’s entropy model. The spatial association between influencing factors and induced landslides has been measured by introducing the variable fractal dimension method (VFDM). The VFDM approach fully considers the characteristics of landslide fractal distribution. Then the fractal dimensions (\(D\)) are calculated to provide multiple factors with various numerical weights. The proposed model eventually combines the landslide frequency ratio (\(fr\)) of each factor with corresponding weight to achieve spatial prediction of landslides, illustrated by an example area in China. In the study area, 500 landslides have been identified by aerial photograph interpretation, extensive field investigations, historical and bibliographical landslide data. In the model, these landslides are randomly split into a training dataset (70 %)and a validating dataset (30 %) Seven factors are recognized and analyzed by frequency ratio (FR) method, including lithology, distance to fault, altitude, slope, aspect, distance to stream and distance to the road. The receiver operating characteristic curve (AUROC) has been adopted to compare and validate the model results. Results show that the proposed landslide model achieved a more accurate prediction with AUROC equal to 0.8467, over-performing than the conventional frequency ratio method (AUROC=0.8088). According to the final prognostic landslide susceptibility map, 16.37 % f the study area shows very high and high susceptibility, accounting for 63.55 % f the entire landslides. Evaluation of relative factor importance based on a one-by-one factor removal test indicates that the lithology factor contributes unique information for landslides. In conclusion, the example demonstrates that the proposed framework is promising for further improvement of LSM.

Abstract
PurposeWe explored the clinical data of colorectal cancer patients treated with oxaliplatin-based regimen to determine the incidence, severity, and risk factors of oxaliplatin-related hypersensitivity reaction (HSR). MethodThis retrospective study investigated 245 colorectal cancer patients (1,690 treatment cycles) receiving care at King Chulalongkorn Memorial Hospital, Thai Red Cross society between January 1, 2015, and December 31, 2019. The patients’ demographic data, laboratory data, and clinical features suggesting hypersensitivity reactions to oxaliplatin were reviewed. The Fisher’s Exact test and unpaired t-test were used to determine the differences among patients with and without oxaliplatin HSR. The potential risk factors for oxaliplatin HSR were analyzed for statistical significance by logistic regression.Results A total of 245 colorectal cancer patients (1,690 treatment cycles) were included in this study. The incidence of oxaliplatin HSR was 37.96%, according to the NCI-CTCAE v.5, (grade 1, grade 2, and higher grades were 27.35% (67 patients), 6.53% (16 patients), and 4.08% (10 patients), respectively). The proportion of male patients and patients with history of prior exposure to platinum-based chemotherapy were statistically higher in the HSR group. The eosinophil count and serum creatinine level were also significantly greater in the HSR group. On the contrary, the total lymphocyte count and serum albumin level were significantly lower in the HSR group. The multivariate logistic regression found 5 risk factors with significant difference. Male gender, prior exposure to platinum-based chemotherapy, and elevated eosinophil count were associated with increased risk of oxaliplatin HSR, whereas elevated monocyte count and elevated serum albumin were protective factors for the development of oxaliplatin HSR. ConclusionColorectal cancer patients treated with oxaliplatin-based regimen with male gender, prior exposure to platinum-based chemotherapy, and elevated eosinophil count have a greater risk of oxaliplatin related hypersensitivity reactions.

Abstract
BackgroundIncidence of adenocarcinoma of the esophagogastric junction (AEG) is increasing in Japan as well as Western Country. However, there is no consensus on treatment strategy. The purpose of this study was to determine the optimal range of resection and lymph node dissection for Siewert type II AEG and to develop a strategy for treatment that includes adjuvant therapy to improve the survival rate. MethodsWe retrospectively investigate 88 cases of advanced AEG in patients who underwent surgery with lymph node dissection with 52 cases of superficial AEG, 23 of whom underwent endoscopic treatment (endoscopic mucosal resection [EMR] or endoscopic submucosal dissection [ESD]), and 29 of whom underwent surgery with lymph node dissection. Results The optimal lymph nodes to resect for advanced AEG were in the inferior mediastinum (No. 110), in the lesser curvature (Nos. 1, 3, 7), No. 2, and No 11. According to area of actual lymph node metastasis, lymphadenectomy of lymph nodes 1, 2, 3, 7, and 11 was sufficient to improve survival of patients with superficial AEG. If esophageal involvement was >40 mm, we performed esophagectomy through right thoracotomy. The 5-year overall survival rates were 88% for patients treated with ESD, 78% for those with superficial AEG who under-went surgery, and 24% for those with advanced AEG (p = 0.011). Despite of lymph node dissection, twenty-five patients experienced lymph node metastasis after operation in advanced AEG and there were many disseminations in advanced AEG. There were no differences in survival between patients who received postoperative adjuvant therapy with S-1 for advanced AEG and those who received surgery alone (p = 0.5192).ConclusionAlthough surgical procedures of superficial and locally advanced AEG are standardized, the role of adjuvant therapy for AEG is still controversial. We recommend nab-paclitaxel plus radiotherapy for advanced AEG as neoadjuvant therapy.

Abstract
Background

Vaccination is the most effective approach against the coronavirus disease 2019 (COVID-2019) pandemic. This study aimed to investigate acceptance and the predominant influential factors of COVID-19 vaccination among people living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS).
Methods

A cross-sectional survey was carried out in five cities in Guangxi from 7 May to 1 June 2021. Questionnaires on the acceptance of COVID-19 vaccination and the influential factors were conducted among HIV/AIDS patients recruited by random cluster sampling. We performed univariate and multivariate logistic regression analysis to identify factors associated with acceptance of COVID-19 vaccination among HIV/AIDS patients.
Results

Of all the participants (n = 903), 72.9% (n = 658) were willing to accept the COVID-19 vaccine and there was no statistically significant difference between CD4+T cell count and willingness to vaccinate using stratified analysis (P > 0.05). The main reason for willingness to accept the COVID-19 vaccine was fear of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (76.0%), whereas patients who were reluctant to receive the vaccine were mainly concerned about the safety of the vaccine (54.7%) and whether it would impact anti-retroviral therapy(ART) efficacy (50.6%). The most significant factors influencing vaccination were concerns that the vaccine was unsafe in HIV patients (OR=0.082, 95%CI = 0.024–0.282) and that it would be less effective in preventing SARS-CoV-2 infection in HIV patients (OR = 0.093, 95%CI = 0.030–0.287). Other factors associated with acceptance of the COVID-19 vaccine included Zhuang ethnicity (OR=1.653, 95%CI=1.109–2.465), the highest education level of middle school and high school or above (OR=1.747, 95%CI=1.170–2.608; OR=2.492, 95%CI=1.326–4.682), unknown vaccination type (OR=0.487, 95%CI=0.305–0.776) and little vaccine influence on ART efficacy (OR=2.889, 95%CI=1.378-6.059).
Conclusions

Acceptance of the COVID-19 vaccination is high among HIV/AIDS patients, although some patients refused vaccination because of vaccine safety and influence on ART efficacy. More research is needed to investigate the impact of the COVID-19 vaccine on the efficacy of ART and to evaluate its effectiveness in preventing SARS-CoV-2 infection in HIV patients so that concerns about COVID-19 vaccination issues can be addressed in HIV patients.

Abstract
Background

Little is known about the epidemic status of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in cats living in Japan, and about the influence of cat lifestyles on the SARS-CoV-2 infection epidemic in cats.
Results

We developed protein A/G-based ELISA, which was standardized using positive rabbit antibodies. The measured values of this ELISA were consistent with those of conventional anti-feline IgG-based ELISA. We then collected blood samples from 1,969 cats that visited veterinary clinics in Japan from June to July 2020 and examined for the presence of anti-SARS-CoV-2 antibodies. Using protein A/G-based ELISA, nine cats were found to have SARS-CoV-2 S1-specific IgG, among which four had RBD-specific IgG. Among those nine samples, one showed neutralizing activity. Based on these, we estimated that the prevalence of SARS-CoV-2 neutralizing antibodies in cats living in Japan was 0.05% (1/1,969 samples). This prevalence did not differ much from the prevalence of neutralizing antibodies for SARS-CoV-2 in humans conducted in Japan at that time. Furthermore, we searched for factors associated with the prevalence of neutralizing antibodies in cats using our data and information from five countries (China, Croatia, France, Germany, and Italy). The prevalence of SARS-CoV-2 in cats was correlated with the rate of keeping indoor-only.
Conclusions

Protein A/G-based ELISA has the potential to be a standardized method to measure anti-SARS-CoV-2 antibodies in cats. The infection status of SARS-CoV-2 in cats in Japan is linked to that in humans, and the epidemic of SARS-CoV-2 infection in cats may be controlled by their living environment.

Published: January 2022

Abstract
Background
Age-related lower urinary tract symptoms (LUTS) is a common disease in the elderly. The reduction of urinary flow rate (UFR) as an assessment of LUTS is associated with cognitive impairment. The association between UFR and cognitive performance has not been studied to date.
Methods
We used data from the 2011 to 2014 U.S. National Health and Nutrition Examination Survey (NHANES). Finally, 2,724 participants aged 65-80 with available data on UFR and cognitive assessments were included. The cognitive function assessment used the digit symbol substitution test (DSST), Animal Fluency Test (AFT) and the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) immediate recall test. Multivariate logistic regressions were used to assess the association between UFR (exposure) and cognitive performance (outcome). Additionally, to ensure the reliability of data analysis, we converted UFR into categorical variables through tertile and then calculated the P for trend.
Results
Among 2,724 participants, the mean (SD) age was 69.26 (6.65) years, and 54.56% were women. After adjusting for covariates, UFR showed a positive correlation with DSST score (β = 2.00, [95%Cl:1.20-2.80], P<0.0001), AFT score (β = 0.57,[95%Cl:0.28-0.87], P=0.0001), CERAD immediate score(β = 0.24, [95%Cl:0.01-0.47], P=0.0435). In addition, we found a similar linear trend when UFR was regarded as a categorical variable (tertile) (P for trend <0.0001(both in AFT and DSST); P for trend =0.0403 in CERAD immediate test).
Conclusions
The decrease of UFR is related to cognitive decline in the elderly, which may suggest that UFR may be a clinical marker of predicting cognitive decline.

Abstract
BackgroundLong-term fasting for elective surgery has been proven unnecessary based on established guidelines. Instead, preoperative carbohydrate loading 2 hours before surgery and recommencing oral nutrition intake as soon as possible after surgery is recommended. This study was performed to analyze the compliance with and effect of abbreviated perioperative fasting management in patients undergoing surgical repair of fresh fractures based on current guidelines.MethodsPatients with fresh fractures were consecutively enrolled from May 2019 to July 2019 at our hospital. A carbohydrate-enriched beverage was recommended up to 2 hours before surgery for all surgical patients except those with contraindications. Postoperatively, oral clear liquids were allowed once the patients had regained full consciousness, and solid food was allowed 1 to 2 hours later according to the patients’ willingness. The perioperative fasting time was recorded and the patients’ subjective comfort with respect to thirst and hunger was assessed using an interview-assisted questionnaire.ResultsIn total, 306 patients were enrolled in this study. The compliance rate of preoperative carbohydrate loading was 71.6%, and 93.5% of patients began ingestion of oral liquids within 2 hours after surgery. The median (interquartile range) preoperative fasting time for liquids and solids was 8 (5.2–12.9) and 19 (15.7–22) hours, respectively. The median postoperative fasting time for liquids and solids was 1 (0.5–1.9) and 2.8 (2.2–3.5) hours, respectively. A total of 70.3% and 74.2% of patients reported no thirst or hunger during the perioperative period. Logistic regression analysis showed that the preoperative fasting time for liquids was an independent risk factor for perioperative hunger. No adverse events such as aspiration pneumonia or gastroesophageal reflux were observed.ConclusionsIn this study of a real clinical practice setting, abbreviated perioperative fasting management was carried out with high compliance in patients with fresh fractures. The preoperative fasting time should be further shortened to further improve patients’ subjective comfort.

Abstract
PurposeTo explore the dynamic changes in Quality of Life (QoL), anxiety/depression status, and body image (BI) of women who received different types of breast cancer (BC) surgery within an 8-years follow-up period.MethodsWomen with major BC surgeries were invited to complete the World Health Organization Quality of Life–Brief (WHOQOL-BREF), the European quality of life five dimensions questionnaire (EQ-5D), and a body image scale within 8 years of surgery. Kernel smoothing methods were applied to describe dynamic changes in QoL, anxiety/depression, and BI at different time points. Linear mixed effects models were constructed to identify the interaction between time, different types of surgery, and the determinants of QoL in these patients.ResultsA total of 1,803 women who had undergone a mastectomy, a modified radical mastectomy (MRM), and breast reconstruction (BR) were included. The BR group exhibited a high QoL score of WHOQOL one to five years after surgery with some fluctuations. The MRM group had comparatively stable, low QoL scores of WHOQOL items and less depressed/anxious. BR group generally showed fluctuated, lower scores of BI two years after operation, but they exhibited more anxiety/depression status after five years. Medical comorbidities, the status of anxiety/depression, and BI were the major factors influencing all domains and items of the WHOQOL BREF.Conclusion﻿While MRM may decrease the likelihood of depression in patients with BC and BR would significantly improve their QoL in the first 5 years. We recommend that these findings should be considered and discussed in the patient participatory decision-making for breast surgery.

Abstract
Objectives. The objectives of this study are to assess the dental awareness in reducing the risk of Medication-Related Osteonecrosis of the Jaw (MRONJ) among non-head and neck cancer patients and their barriers of attending pre-medication dental evaluation (PMDE). Methodology: This study was conducted in the Department of Oncology of the University of Malaya Medical Centre. Non-head and neck cancer patients who are currently or will be undergoing anti-resorptive and/or anti-angiogenic therapy were interviewed using a questionnaire that consist of questions on patient’s awareness, attitude, and barriers of receiving PMDE. Ethics approval was obtained. Results. In total, 17 patients were interviewed. Only 6 patients were informed by the medical doctors about the risk of MRONJ. Nine patients were advised by the medical doctors to have the PMDE prior to the therapy, and most of them in this group follow the instruction and already had their PMDE done prior to the therapy. The other 8 patients, who did not attend a PMDE, thought it was not important because their medical doctors neither inform them about MRONJ, nor refer them for PMDE. Conclusion. Patients’ awareness of MRONJ risks and preventive strategies are poor. The main barrier for PMDE is the lack of referral and information on MRONJ from the medical doctors. Patients’ attitudes were positive towards PMDE if they were referred by the medical doctors.

Published: January 2022

Abstract
We have examined the uptake mechanisms of platinum-group-metals (PGMs) and molybdenum (Mo) ions into PBNPs in a nitric acid solution for 24-h sorption test, using inductively coupled plasma atomic emission spectroscopy, powder XRD, and UV-Vis-NIR spectroscopy in combination with first-principles calculations, and revealed that the Ru4+ and Pd2+ ions are incorporated into PBNPs by substitution with Fe3+ and Fe2+ ions of the PB framework, respectively, whereas the Rh3+ ion is incorporated into PBNPs by substitution mainly with Fe3+ and minorly with Fe2+ ion, and Mo6+ ion is incorporated into PBNPs by substitution with both Fe2+ and Fe3+ ions, with maintaining the crystal structure before and after the sorption test. Assuming that the amount of Fe elusion is equal to that of PGMs/Mo substitution, the substitution efficiency is estimated to be 39.0% for Ru, 47.8% for Rh, 87% for Pd, and 17.1% for Mo6+. This implies that 0.13 g of Ru, 0.16 g of Rh, 0.30 g of Pd, and 0.107 g of Mo can be recovered by using 1g PBNPs with a chemical form of KFe(III)[Fe(II)(CN)6].

Abstract
Sensors for detecting glucose concentrations are crucial to medical testing. Here, we introduce silver nanoparticles (Ag NPs) uniformly distributed in space to investigate the sensing properties for detecting glucose by using the finite-different time-domain (FDTD) and experimental methods. The results show that the transmittance of dip for the proposed structural model gradually decreases as the number of Ag NPs increases, when the concentration of glucose is constant. And the transmission spectrum shows slight red shift with the increasing of the glucose concentration. Moreover, the simulation results are in agreement with the experimental results. Especially, the maximum sensitivity S=1144.07407 nm/RIU can be realized for glucose concentration variation from 0.3 to 0.4 mol/L. The research results reveal an excellent sensing property that has important application value in medical detection.

Abstract
In this paper, the physical adsorption characteristics of oxygen in coal pores were systematically investigated by the Grand Canonical Monte Carlo and the COMPASS force field. Firstly, coal pore structures of different sizes were constructed by graphite slit models and different groups. Secondly, the physisorption behavior of oxygen in graphite slit models of different sizes was simulated. Finally, the physisorption behavior of oxygen in graphite slit models at different pressures and temperatures was analyzed. The results showed that the physisorption density and excess physical adsorption of oxygen were divided into the rapidly decreasing stage (0.4-0.7 nm), the slowly decreasing stage (0.7-1.4 nm), and the stable stage (1.4 nm-5 nm) with the increase of coal pores, and the excess oxygen physisorption amount was more sensitive to the change of pressure. The O2 isosteric heat of physisorption decreased with increasing pore size of coal. Oxygen is more strongly adsorbed by hydroxyl and ether bonds than by methyl, carboxyl and carbonyl groups. Through this study, the mechanism of oxygen physical adsorption in coal pores and the characteristics influenced by temperature and pressure can be better understood.
