Published: January 2021

Abstract
Complex networks in the real world are often with heterogeneous degree distributions. The structure and function of nodes can vary significantly, with influential nodes playing a crucial role in information spread and other spreading phenomena. Identifying high-degree nodes enables change to the network’s structure and function. Previous work either redefines metrics used to measure the nodes’ importance or focus on developing algorithms to efficiently find influential nodes. These approaches typically rely on global knowledge of the network and assume that the structure of the network does not change over time, both of which are difficult to achieve in the real world. In this paper, we propose a decentralized strategy that can find influential nodes without global knowledge of the network. Our Joint Nomination (JN) strategy selects a random set of nodes along with a set of nodes connected to those nodes, and together they nominate the influential node set. Experiments are conducted on 12 network datasets, including both synthetic and real-world networks, both undirected and directed networks. Results show that average degree of the identified node set is about 3–8 times higher than that of the full node set, and the degree distribution skews toward higher-degree nodes. Removal of influential nodes increase the average shortest path length by 20–70% over the original network, or about 8–15% longer than the other decentralized strategies. Immunization based on JN is more efficient than other strategies, consuming around 12–40% less immunization resources to raise the epidemic threshold to 𝜏 ~ 0:1. Susceptible-Infected-Recovered (SIR) simulations on networks with 30% influential nodes removed using JN delays the arrival time of infection peak significantly and reduce the total infection scale to 15%.

Abstract
Background: Human papilloma virus infection and tobacco smoking are the major risk factors for cervical cancer. There are limited studies searching other risk factors for cervical cancer and the results are not consistent. This study investigated the relations between cervical cancer and possible risk factors, including secondhand cigarette smoke exposure, diabetes, work schedule. Methods: In this cross-sectional study, 29,557 women completed a cervical cancer questionnaire and were selected using 2010–2018 data from the Korea National Health and Nutrition Examination Survey. Details in secondhand smoke exposure, diabetes, work schedule were assessed from participants’ health interviews and blood test results were used for fasting glucose level and hemoglobin A1c (HbA1c) level.Results: Two hundred sixty-two women (0.89%) in the sample were diagnosed with cervical cancer. Domestic secondhand smoke exposure, diabetes, high fasting glucose level, and high HbA1c significantly increased cervical cancer risk. The respective odd ratios and 95% confidence intervals were: 1.488 (1.002–2.207), 2.369 (1.713–3.274), 1.008 (1.005–1.009), and 1.304 (1.193–1.425). Weekly work hours and work schedule were not significantly related to cervical cancer incidence.Conclusion: Among Korean women, passive exposure to cigarette smoke at home, diabetes, elevated fasting glucose level, and high HbA1c level all increase risk for cervical cancer.
Material Resources and Body Fatness in an East German Adult Population: Insights From the LIFE-adult-study&nbsp;
Authors: Enzenbach Cornelia , Kowall Bernd 
Published: January 2021

Abstract
Background. Obesity has been postulated to be a consequence of economic disadvantage. However, epidemiological studies failed to demonstrate a consistent link between income and body fatness. We examined income as a possible cause of obesity in an East German general population, focusing on appropriate representation of study variables, as well as on confounding and modification of the income-obesity association.Methods. We used data of 9,599 participants in the baseline examination of the LIFE-Adult-Study, conducted in the city of Leipzig from 2011 to 2014. Body mass index (BMI) and waist circumference (WC) as obesity measures were based on standardised measurements, net equivalised income (NEI) on self-reports. We estimated adjusted means of BMI and WC within NEI categories representing the range from risk of poverty to affluence. We stratified the analyses by gender, age, and education. Results. A substantial part of the age-adjusted associations of income with obesity measures was attributable to other SES indicators. Adjusted for these variables, NEI was comparably associated with BMI and WC. Among women, BMI and WC decreased across NEI categories. The inverse associations tended to be stronger at non-working age (≥ 65 years) than at working age (< 65 years). Conversely, among working-age men, BMI and WC increased with increasing NEI. Among older men, risk of poverty was related to higher values of the obesity measures. The aforementioned associations were predominantly stronger in highly educated participants compared to those with medium/low education. The differences in mean BMI and WC between persons at risk of poverty and higher income groups were rather small, ranging from 1 to 2 kg/m2 for BMI and 2 to 4 cm for WC. Conclusions. Our investigation indicates an association between material resources and body fatness in an East German adult population that depends on the sociodemographic context of the people. However, it does not suggest that income disparities are a major driver of body fat accumulation in this population. Differential selection of study participants, error in the measurement of long-term income, and possibly reverse causality may have affected our conclusions.

Published: January 2021

Abstract
Background: Background parenchymal enhancement (BPE) and mammographic breast density are risk factors for breast cancer. However, existing evidence regarding the association between these risk factors is inconclusive. This study aimed to evaluate the relationship between BPE and quantitative and subdivided mammographic density parameters, such as fibroglandular tissue (FGT) volume, entire breast volume, and volumetric density (%), measured using a fully automated volumetric software.Methods: From July 2017 to August 2018, patients with newly diagnosed breast cancer who had undergone preoperative mammography and magnetic resonance imaging (MRI) at our hospital were identified. Mammographic density analysis was performed using a fully automated volumetric software. Two breast radiologists consensually rated BPE and the amount of FGT in each contralateral normal breast MRI based on four categories of the Breast Imaging-Reporting and Data System. The Pearson correlation coefficient was used to analyze the relationship between mammographic density and the FGT and BPE observed on breast MRI.Results: A total of 364 women were included, of whom 153 (42%) were premenopausal (mean age, 44.22±6.29 years) and 211 (58%) were postmenopausal (mean age, 57.91±9.59 years).The premenopause group had significantly higher levels of BPE and FGT on MRI and FGT volume and volumetric density (%) on mammography. FGT and BPE observed on breast MRI were correlated in the overall sample and postmenopause group(r=0.352and 0.265, respectively). The FGT volume on mammography was significantly correlated with BPE in the overall sample and in the pre- and postmenopause groups (r=0.290, 0.166, and 0.294, respectively). Volumetric density (%) on mammography and BPE were correlated in the total sample and postmenopause group(r=0.369 and 0.281, respectively). Conclusion: Mammographic breast density and BPE on MRI are significantly correlated in patients with breast cancer. The mammographic FGT volume is particularly correlated with BPE on MRI, regardless of the patient’s menopausal state.

Abstract
Background: Patients with insulin-dependent diabetes mellitus type 1 (IDDM1) and end-stage kidney disease (ESKD) undergoing simultaneous pancreas kidney transplantation (SPKT) are a population with diffuse atherosclerosis and elevated risk of cardio- and cerebrovascular morbidity and mortality. We aimed to investigate the feasibility of preoperative screening for peripheral arterial disease (PAD), specifically ankle-brachial index (ABI) testing, to predict peri- and postoperative outcomes in SPKT recipients. Methods: Medical data (2000–2016) from all patients with IDDM and ESKD undergoing SPKT at our transplant center were retrospectively analyzed. The correlation between PAD (defined by an abnormal ABI before SPKT and graft failure and mortality rates as primary end points, and the occurrence of acute myocardial infarction, cerebrovascular and peripheral vascular complications as secondary end points were investigated after adjustment for known cardiovascular risk factors.Results: Among 101 SPKT recipients in our transplant population who underwent structured physiological arterial studies, 17 patients (17%) were diagnosed with PAD before transplantation. PAD, as defined by a low ABI index, was an independent and significant predictor of death (HR, 2.99 (95% CI, 1.00-8.87), p = 0.049) and pancreas graft failure (HR, 4.3 (95% CI 1.24-14.91), p = 0.022). No significant differences were observed for kidney graft failure (HR 1.85 (95% CI 0.76-4.50), p = 0.178). In terms of the secondary outcomes, patients with PAD were more likely to have myocardial infarction, stroke, limb ischemia, gangrene or amputation (HR, 2.90 (95% CI, 1.19-7.04), p = 0.019).Conclusions: Pre-transplant screening for PAD and cardiovascular risk factors with non-invasive ABI testing may help to reduce perioperative complications in high-risk patients. Future research on long-term outcomes might provide more in depth insights in optimal treatment strategies for PAD among SPKT recipients.

Published: January 2021

Abstract
Introduction: The management of older patients with breast cancer remains controversial. The difficult assessment of ageing idiosyncrasies and the insufficient evidence of therapeutic guidelines can lead to undertreatment. Our goal was to measure undertreatment and assess its impact on survival.Materials and methods: Consecutive patients with breast cancer aged 70 years or older were prospectively enrolled in 2014. Three frailty screening tools (G8, fTRST, GFI) and two functional status scales (KPS, ECOG-PS) were applied. Disease characteristics, treatment options and causes of mortality were recorded in a 5-year follow-up. We defined undertreatment and correlated its survival impact with frailty. Results: A total of 92 patients were included. Median age was 77 (range 70-94) years. The prevalence of frailty was discordant (G8: 41,9%, fTRST: 74.2%, GFI: 32.3%). A low-risk disease was not found (51.2% were N+) probably due to a late diagnosis (76.1% based on self-examination). Thirty-three patients (35.6%) died 15 of them from breast cancer. We found a considerable high proportion (53.3%) of undertreatment, which had a frailty-independent negative impact on 5-year survival (HR=5.1 [95% CI: 2.1-12.5]). Additionally, omission of surgery had a frailty-independent negative impact on overall survival (HR=3.9 [95% CI: 1.9-7.9]). Conclusion: Breast cancer treatment in older adults ought to be individualized. More important than assessing frailty (not to treat) is essential to be aware of the risk-benefit profile and the patient's well-informed willingness to be treated. The undertreatment in daily practice is frequent and might have, as we report, a negative impact on survival.

Abstract
Background: Complementary experiments on nanomedicines as proper candidates for the control and treatment of cancer are widely being conducted nowadays. In the previous study, the effect of BCc1 nanomedicine, which is synthetized based on nanochelating technology, on overall survival (OS) and quality of life of gastric cancer patients was evaluated after 18 months of consumption. The OS of the same patients is reported in this study after 40 months. Methods: A double-blind, randomized, placebo-controlled, parallel, multicenter design was used in this study. 123 metastatic and non-metastatic gastric cancer patients of both genders (between 25 and 85 years old) participated in this experiment to evaluate their OS after consuming BCc1 for 40 months and to identify the adverse events of this nanomedicine. Results: The median OS of metastatic patients was 257 days in the BCc1 group [95% confidence interval (CI): 144. 142-369.858], while it was 161 days in the placebo [95% CI: 118.462-203.538]; hazard ratio (HR): 0.802 [95% CI: 0.483-1.333] (P-Value = 0.395). Similarly, the median OS of non-metastatic patients was 718 days in the BCc1 group [95% CI; 577.706-860.213], while it was 520 days in the placebo [95% CI: 460.280- 580.690]; HR: 0.807 [95% CI: 0.343,1.902] (P-Value = 0.624). There was no evidence of adverse events after 40 months.Conclusion: The OS improvement of metastatic and non-metastatic gastric cancer patients in the previous (18 months of follow-up) and current (40 months of follow-up) studies showed that BCc1 can be used along with base treatments to improve cancer patients’ OS.

The TLR-2/TonEBP Signaling Pathway Regulates 29-kDa Fibronectin Fragment-dependent Expression of Matrix Metalloproteinases
Authors: Hwang Hyun Sook , Lee Mi Hyun , Kim Hyun Ah 
Published: January 2021

Abstract
Tonicity-responsive enhancer-binding protein (TonEBP; nuclear factor of activated T cells 5) is a transcription factor that responds to changes in osmolality. However, recent studies have shown that it also modulates immune responses under inflammatory conditions independently of hyperosmolality. Fibronectin fragments (FN-fs), which are abundant in the synovial fluid of patients with osteoarthritis (OA), induce expression of matrix metalloproteinases (MMPs) via the toll-like receptor-2 (TLR-2) signaling pathway. In this study we examined whether TonEBP is involved in 29-kDa FN-f-induced expression of MMPs. The expression of TonEBP was significantly higher in human osteoarthritis compared with normal cartilage samples. 29-kDa FN-f affected the expression of MMPs 1, 3, and 13 via TonEBP, and expression and nuclear accumulation of TonEBP were induced by activation of the phospholipase C/NF-κB/MAPK signaling pathway and, in particular, modulated by TLR-2. In addition, 29-kDa FN-f induced the expression of osmoregulatory genes, including Tau-T, SMIT, and AR, as well as voltage-dependent calcium channels via the TonEBP/TLR-2 signaling pathway. These results show that 29-kDa FN-f upregulates MMPs in chondrocytes via the TLR-2/TonEBP signaling pathway.
Development of a physically-informed neural network interatomic potential for tantalum
Authors: Lin Yi-Shen , Pun G. Purja , Mishin Yuri 
Published: January 2021

Abstract
Large-scale atomistic simulations of materials heavily rely on interatomic potentials, which predict the system energy and atomic forces. One of the recent developments in the field is constructing interatomic potentials by machine-learning (ML) methods. ML potentials predict the energy and forces by numerical interpolation using a large reference database generated by quantum-mechanical calculations. While high accuracy of interpolation can be achieved, extrapolation to unknown atomic environments is unpredictable. The recently proposed physically-informed neural network (PINN) model significantly improves the transferability by combining a neural network regression with a physics-based bond-order interatomic potential. Here, we demonstrate that general-purpose PINN potentials can be developed for body-centered cubic (BCC) metals. The proposed PINN potential for tantalum reproduces the reference energies within 2.8 meV/atom. It accurately predicts a broad spectrum of physical properties of Ta, including (but not limited to) lattice dynamics, thermal expansion, energies of point and extended defects, the dislocation core structure and the Peierls barrier, the melting temperature, the structure of liquid Ta, and the liquid surface tension. The potential enables large-scale simulations of physical and mechanical behavior of Ta with nearly first-principles accuracy while being orders of magnitude faster. This approach can be readily extended to other BCC metals.

Abstract
BACKGROUND: Ascertaining the cause for deaths occurring outside health facilities is a significant problem in many developing countries where civil registration systems are poor or non-functional. Standardized and rigorous verbal autopsy methods is a potential solution determine the cause of death. We conducted a demonstration project in Lusaka District of Zambia where verbal autopsy (VA) method was implemented in routine civil registration system. METHODS: About 3400 VA interviews were conducted for the “brought-in-dead” cases at Lusaka’s two major hospital mortuaries using a SmartVA questionnaire between October 2017 and September 2018. Probable underlying causes of deaths using VA and cause-specific mortality fractions were determined for each cause. Demographic characteristics associated with each cause were analyzed. RESULTS: Opportunistic infections associated with HIV/AIDS such as pneumonia, tuberculosis and malaria were among leading causes of deaths among cases of “brought-in-dead”. Over 21% and 27% of deaths were attributable to external causes and non-communicable diseases, respectively. The VA-ascertained causes of death varied by age-group and sex. External causes were more prevalent among males in middle ages (put an age range like 30-54 years old) and NCDs highly prevalent among those aged 55 years and older CONCLUSIONS: VA application in civil registration system can provide the much needed cause of death information for non-facility deaths in countries with poor civil registration system.

Abstract
Background: To investigate left atrial(LA) function in essential hypertension(EHT) patients by using volume-derived values, two-dimensional strain. Methods: 51 normal subjects and 95 EHT patients(without LVH: 50, and with LVH: 45) were enrolled for this research. LA Volume-derived index was measured in apical 4-, 2-chamber views by Simpson′s method. LA strain(S-reservoir, S-conduit, S-booster pump) and strain rate (SR-reservoir, SR-conduit, SR-booster pump), representing the reservoir, conduit and booster pump functions, respectively, were measured by two-dimensional speckle tracking echocardiography(STE).Results: Volume-derived values(contain Total LAEF, passive LAEF and active LAEF) and strain-derived values(S-reservoir, S-conduit, Sr-reservoir, Sr-conduit and Sr-booster pump) in EHT patients were significantly lower than normal subjects. Correlation test showed LA stiffness had a strong correlation with LA conduit function in EHT patients. The AUC values were higher for detection LA conduit function than LA reservoir and booster pump function in EHT patients. LA expansion index and LA stiffness also have the higher AUC with higher sensitivity and specificity values for detection the LA dysfunctions in EHT patients. Conclusions: In this study, we concluded that LA functions were damaged in EHT patients, which could be detect by LA volume-derived values and two-dimensional strain sensitively and reproductively. LA stiffness maybe a predictor for LV remodelling in EHT patients.
