Published: July 2020

Abstract
Background and purpose: Abdominal desmoid tumors (ADTs) are rare soft-tissue neoplasms that have a relatively high local recurrence rate. The purpose of the present study was to delineate the clinicopathologic features and explore the prognostic factors of ADTs.Methods: From January 2000 to January 2019, patients with ADTs who underwent macroscopically complete resection at the China National Cancer Center were included in the study. The clinicopathologic characteristics and follow-up data were carefully collected and reviewed. Prognostic factors such as age at presentation, sex, tumor location, tumor size and tumor proximity to nerves or vasculature were analyzed, and recurrence-free survival was analyzed with these factors.Results: A total of 113 patients with ADTs were assigned to the abdominal wall group (n = 66) or abdominal cavity group (n = 47) according to the tumor site. Abdominal wall DTs and intra-abdominal DTs demonstrated distinct clinicopathological features and prognoses. During a median 61-month follow-up period, twelve (10.2%) patients had local recurrence. According to the univariate and multivariate analyses, intra-abdominal tumors, large tumors, and positive margins were independent risk factors for poor prognosis.Conclusion: Compared with intra-abdominal DTs, abdominal wall DTs demonstrate different clinicopathological features and a better prognosis. Under the premise of ensuring negative margins during the first surgical procedure, patients with abdominal wall DTs can obtain satisfactory prognoses through radical resection.

Abstract
Background: Resource utilization strategies of avian migrants are a major concern for conservation and management. Consequently, the ability to predict potential shifts in migratory species distribution and migratory behaviour is a pressing challenge for predictive ecology under global changes. There are two main strategies of resource use adopted by migratory birds: niche tracking for similar environmental conditions and niche switching between different environmental conditions between seasons. Our objective was to examine whether the “niche tracker” or “niche switcher” hypothesis would better explain seasonal variations in the ecological niche breadth and overlap of the American White Pelicans (AWPE, Pelecanus erythrorhynchos). We also tested whether recent changes in the non-breeding ground land-use have altered the land-cover niche breadth of AWPE. Methods: We built Maximum Entropy Models (MAXENT) to predict the AWPE breeding and non-breeding ranges using GPS locations, climate variables, and land-cover variables. We then compared the estimated climatic and land-cover niche breadth and the overlap between the breeding and non-breeding grounds. Results: Our climate, land-cover, and combined species distribution models had a good to excellent predictive performance. Our findings supported the hypothesis that AWPE would be climatic niche switchers. American white pelicans showed little climatic niche overlap between nesting and wintering seasons. Migrants on the breeding grounds showed broader climatic niche than both residents and migrants on the non-breeding grounds. Finally, declines in availability of food resources provided by commercial aquaculture on the non-breeding grounds appeared to increase land-cover niche breadth.Conclusions: Climatic niche switching suggests that AWPE may adapt to future climate changes with unexpected spatial distributions under global change. Future declines in wetlands and food resources may restrict AWPE spatial distributions. Future studies need to investigate AWPE demographic consequences of climate and land-use changes.
The Relative Importance and Stability of Disease Burden Causes Over Time: Summarising Regional Trends on Disease Burden for 290 Causes Over 28 Years
Authors: Dyson Henry , Gestel Raf Van , Doorslaer Eddy van 
Published: July 2020

Abstract
Background Since the Global Burden of Disease study (GBD) has become more comprehensive, data for hundreds of causes of disease burden, measured using Disability Adjusted Life Years (DALYs), have become increasingly available for almost every part of the world. However, undergoing any systematic comparative analysis of the trends can be challenging given the quantity of data that must be presented.Methods We use the GBD data to describe trends in cause-specific DALY rates for eight regions. We quantify the extent to which the importance of ‘major’ DALY causes changes relative to ‘minor’ DALY causes over time by decomposing changes in the Gini coefficient into ‘proportionality’ and ‘reranking’ indices.Results The fall in regional DALY rates since 1990 has been accompanied by generally positive proportionality indices and reranking indices of negligible magnitude. However, the rate at which DALY rates have been falling has slowed and, at the same time, proportionality indices have tended towards zero. These findings are clearest where the focus is exclusively upon non-communicable diseases. Notably, large and positive proportionality indices are recorded for sub-Saharan Africa over the last decade. Conclusion The positive proportionality indices show that disease burden has become less concentrated around the leading causes over time, and this trend has become less prominent as the DALY rate decline has slowed. The recent decline in disease burden in sub-Saharan Africa is disproportionally driven by improvements in DALY rates for HIV/AIDS, as well as for malaria, diarrheal diseases, and lower respiratory infections.

Abstract
Objective
Dirofilaria immitis commonly infects Australian dogs. Studies on the prevalence of infection by this parasitic helminth in Australia cats are rare and relatively old. Data obtained from other countries would suggest a likely prevalence of 4.7–16%. The current study aimed to determine the prevalence of D. immitis in an endemic region of Australia by antigen, antibody and PCR testing.
Methods
172 healthy cats over 6 months of age from the Townsville region of Australia were tested for D. immitis specific antibodies and antigen using a commercially available kit. 50 samples were subsequently retested using a second commercially available antibody kit. 48 of these samples were checked for D. immitis DNA using PCR.
Results
No cat tested positive on any test. The Ausvet Epitools epidemiology calculator was used to calculate prevalences. Maximum antigen (1.27%), antibody (2.1%) and PCR (2.1%) prevalences were calculated.
Conclusion
Our results suggest that the prevalence of heartworm infection in pet cats in this region of Australia is lower than expected based on data from other areas around the world.

Abstract
Background
There is a growing body of evidence showing substantial underuse of appropriate venous thromboembolism (VTE) prophylaxis in patients at risk. In the present study, our goal was to assess the current practices in the use rate of VTE prophylaxis among hospitalized patients in Jordan and Lebanon.
Methods
A cross-sectional, multicenter, observational study was conducted on 40 centers across Lebanon and Jordan. We included patients who were admitted to the participating hospitals for the treatment of a serious medical or surgical illness. The patients’ records were screened for the fulfillment of inclusion/exclusion criteria during a single assessment visit. The proportion of medical and surgical patients who were at risk of VTE and the thrombo-prophylactic measures employed by physicians for these patients were assessed according to the American College of Chest Physicians (ACCP 2016) guidelines.
Results
The present study included 704 patients (400 from Jordan and 304 from Lebanon) with a mean age of 54.9 ± 17.5 years. Almost 59% of the patients received prophylaxis treatment in form of pharmacological anticoagulant prophylaxis and/or mechanical prophylaxis. Low molecular weight heparin was the most commonly used anticoagulant for VTE prophylaxis in 366 out of the total 704 (51.9%) patients in the analysis cohort. Two hundred and sixteen patients (52%, 95% confidence interval [47.1% − 56.9%]) received appropriate prophylactic agents out of 415 patients who were eligible for prophylaxis according to the ACCP 2016 guidelines. On the other hand, 199 (72.1%, 95% confidence interval [66.4% – 77.3%) patients received prophylaxis out of 276 ineligible patients.. The rate of compliance to guidelines showed wide variations according to the type of hospital, specialty, and the patients’ age. The multivariate logistic regression analysis showed that only age was a significant predictor of appropriate VTE prophylaxis (odds ratio [OR] 1.05, P < 0.001).
Conclusion
The rates of the appropriate use of VTE prophylaxis are low in Lebanon and Jordan. There is a lack of compliance to guidelines for VTE prophylaxis use for hospitalized patients in both countries.

Abstract
ObjectiveMetabolic syndrome and diabetes mellitus concurrently potentiates a number of risk factors, significantly higher prevalence of cardiovascular diseases. Numerous risk factors associated with diabetes gets intensified by the presence of metabolic syndrome. Diabetes and metabolic syndrome together can increase the risk of cardiovascular disease by 2 to 4 folds. The main objective of this study was to determine the prevalence of MetS in Type 2 Diabetic patients. Components of metabolic syndrome were measured and compared to determine the prevalence. Hospital based cross-sectional study was conducted from September 2019 to December 2019 at Star hospital and Modern Technical College, Sanepa, Nepal. A total number of 353 patients with type 2 diabetes visiting Star Hospital were included in the study. ResultsAmong 353 participants, metabolic syndrome was diagnosed in 242 (68.5%) participants using NCEP-ATPIII criteria. The prevalence of MetS was 68.5% among which male were 123 (76.3%) and female were 119 (61.9%). MetS was found to be highest in age group of 50-59 years with 34.2% (83) participants. Dyslipidemia with raised TG 71.4% and reduced HDL 76% was found to be most prevalent component in our study followed by hypertension 73.1%.

Abstract
Parapoxvirus (PPV) has been identified in most mammals and poses a great threat to both the livestock production and public health. However, it is still not fully understood the viral prevalence and evolution of PPV coding sequences. Here, we performed a comparative approach integrating viral genetics, molecular selection pressure and genomic structure to investigate the genomic features and evolution of PPVs. We noticed that although there were significant differences of GC contents between ORFV and other three species of PPVs, all PPVs showed almost identical nucleotide bias, that is GC richness. This reflected a common mechanism which determines GC compositions for virus with similar life cycles. The structural analysis of PPV genomes showed the divergence of different PPV species, which may due to the specific adaptation to their natural hosts. Additionally, we estimated the phylogenetic diversity of segmented genome of PPV. Our results suggested that during the 2010 – 2018 outbreak, the orf virus has been the dominant species under the selective pressure of the optimal gene patterns. Furthermore, we found the mean substitution rates were between 3.56×10-5 to 4.21×10-4 in different PPV segments, and the PPV VIR gene was evolved at the highest substitution rate. In these protein-coding regions, purifying selection was the major evolutionary pressure, while the GIF and VIR genes suffered the greatest positive selection pressure. These results may provide useful knowledge on the virus genetic evolution from a new perspective which could help create prevention and control strategies.

Abstract
Purpose: This study aims to compare the nutritional outcomes and quality of life between patients who underwent esophagogastrostomy (EG) and those who underwent the double-tract reconstruction (DTR) after laparoscopic proximal gastrectomy for early gastric cancer.Methods: We retrospectively reviewed the prospectively established database of 45 patients who underwent EG with anti-reflux procedure and 58 patients who underwent the DTR after laparoscopic proximal gastrectomy between December 2013 and June 2017. Then, we compared the baseline characteristics, clinical outcomes, postoperative nutritional parameters, and quality of life (QOL) using EORTC QLQ STO-22 between the EG and DTR groups. Results: In the postoperative 1-year endoscopic findings, the incidence of esophageal reflux was higher in the EG group (17.8% vs. 3.4%, p=0.041) and there was no significant difference in anastomotic stricture. Nutritional status was assessed via body mass index, serum albumin, protein, hemoglobin, and ferritin; we found no significant differences. The incidences of iron deficiency anemia and vitamin B12 deficiency also showed no significant difference between the two groups. With regards to the quality of life, the difference values between preoperative and postoperative 1-year were evaluated; there was no significant difference between the EG with anti-reflux procedure and DTR groups. Conclusions: EG had higher incidence of esophageal reflux and similar nutritional outcomes and QOL compared with the double-tract reconstruction after laparoscopic proximal gastrectomy. Additional large-scale research is needed to evaluate the long-term functional outcomes of EG and the double-tract reconstruction.

Published: July 2020

Abstract
Background: Sarcoma patients should be treated in high volume referral sarcoma centers. Compartmental resection is proposed as best treatment option in retroperitoneal sarcoma patients. Methods: Institute of Oncology Ljubljana is the only referral sarcoma center in Slovenia. Having population of 2.1 million poses a unique situation. We manage all sarcoma patients in the country and operate on patients with soft tissue tumors of extremities, trunk and abdomen. Data for all consecutive patients surgically treated from January 1999 to December 2018 for primary localized retroperitoneal sarcoma was extracted from prospective surgical database. Clinicopathologic variables and the outcome were analyzed.Results: In total 89 patients were included. Mean age was 59.2 years. Dedifferentiated liposarcoma was the most common histology (38.2 %). Mean tumor size was 23.5 cm. Compartmental resection was performed in 47.2 % (42/89). Postoperative complication grade 3a or higher according to Clavien-Dindo classification had 30.3 % (27/89) of patients. The 30-day and 90-day mortality rate was 2.2 % and 5.6 %. Median follow-up was 62.1 months. Corresponding 5-year overall survival was 67.2 %, 5-year disease specific survival was 72.6 % and 5-year local recurrence free survival was 81.5 %, respectively. Conclusion: Results from our institution show that referral sarcoma centers may achieve very good results in management of retroperitoneal sarcoma patients, despite not meeting the criteria for high volume hospitals, as long as they have multidisciplinary team, appropriate facilities and expertise.
Analysis of Deformation Characteristics of AZ31B Friction Heating Incremental Forming
Authors: jiahao Wang , Liuru Zhou , Shiyao Hu 
Published: July 2020

Abstract
A friction heating incremental forming (FHIF) is proposed, which does not require external heating. By means of orthogonal experimental, finite element analysis and CATIA reverse engineering methods, the forming characteristics of magnesium alloy AZ31B FHIF are studied, such as forming limit angle, dimensional accuracy, thickness distribution, equivalent stress and equivalent strain at different forming stages. The results show that: For the FHIF, the forming limit angle can be up to 76°, and the most obvious way to increase the forming limit angle is to increase the spindle speed. In the FHIF, due to the limitations of the experimental conditions, it will be different from the ideal model. The bending phenomenon first occurs in the early stage of forming, which makes the upper corner part the worst accuracy, and the lower corner part obvious defects. Compared with the theoretically stable thickness, the actual part sidewall is thinned by 11%. The simulation successfully predicts and observes the thickness change and stress-strain change trend of the entire FHIF.

Abstract
Due to the recent worldwide outbreak of COVID-19, there has been a huge change in our lifestyle and it has a severe impact in different fields like finance, education, business, travel and tourism, economy in all the affected countries. In this scenario, people have to be careful and cautious about the symptoms and should act accordingly. Accurate predictions of factors, like the end date of the pandemic, duration of lockdown and spreading trend can guide us through the situation and precautions should be taken wisely. Multiple attempts have been made to model the virus transmission, but none of them has investigated it at a global level and concepts like recovery trend analysis in the developed and developing countries have not been discussed ever. The novelty of our proposed work lies here. In this paper, we have analysed the nature of spreading of the said disease using Time Dependent Discrete Susceptible Infected Recovered (TDDSIR) model on the data collected from various platforms and then, fifteen countries from first, second and third world have been considered to have an idea of probable future projections of pandemic. Experimental findings proved that proper social distancing measures during lockdown has been a controller of the disease transmission trend as the basic reproduction number, being actually the transmission rate and not the number of infectives, decreases with the strict lockdown decisions made by different countries. However, people should be more aware of the consequences for quick recovery from the various obstacles of the current situation.

Published: July 2020

Abstract
Background
Rodents play a significant role as reservoirs of zoonotic diseases. Nevertheless, their ectoparasite assemblage and host-ectoparasite associations are poorly known. This study intended to give new insights on the relationships between ectoparasites and rodents in northeastern Iran.
Methods
Rodents were captured using live traps during the year of 2016–2020 and their ectoparasites were collected. Parasitological indices such as infestation rate, prevalence and mean intensity of infestation were analyzed.
Results
A total of 284 rodents, belonging to 17 species, were trapped which infested by 178 ectoparasites from five orders Siphonaptera, Phthiraptera, Ixodida, Mesostigmata and Trombidiformes. Overall infestation rate was 50.3%. Flea Nosopsyllus fasciatus and louse Polyplax asiatica were dominated among all fleas and lice, respectively. Haemaphysalis punctata and Haemolaelaps sp. were recorded as the most abundant tick and mite, respectively. Nosopsyllus fasciatus exhibited low and Polyplax asiatica moderate host specificity. Around 64.2% of ectoparasites shared more than one host and others were singletons. Seasonal fluctuations were found in the occurrence of ectoparasite; fleas and lice were more abundant in spring and winter, respectively. Ticks demonstrated high abundance in spring and summer and mites were more common in autumn. Overall prevalence of ectoparasite on male rodents was greater than females (56.4% vs. 44.4%), while similar mean intensity were detected for both sexes.
Conclusions
This study extend the knowledge on the distribution, seasonality and host choice of four main groups of ectoparasites in associations with rodents. Further studies are needed to can provide deep insight into how relationships and interactions between ectoparasite and rodents are formed, and how they can be applied in epidemiology.
Hybrid prediction method of ECG signals based on VMD, PSR, and RBF neural network

Published: July 2020

Abstract
Background: It is significant for doctors and body area networks (BANs) to predict ECG signals accurately. At present, the prediction accuracy of many existing ECG prediction methods is generally low. In order to improve the prediction accuracy of ECG signals in BANs, a hybrid prediction method of ECG signals is proposed in this paper. Methods: The proposed prediction method combines variational mode decomposition (VMD), phase space reconstruction (PSR), and a radial basis function (RBF) neural network. First, the embedding dimension and delay time of PSR are calculated according to the trained set of ECG data. Second, the ECG data are decomposed into several intrinsic mode functions (IMFs). Third, the phase space of each IMF is reconstructed according to the embedding dimension and the delay time. Fourth, an RBF neural network is established and each IMF is predicted by the network. Finally, the prediction results of all IMFs are added to realize the final prediction result. Results: To evaluate the prediction performance of the proposed method, simulation experiments are carried out on ECG data from the MIT-BIH Arrhythmia Database. The experimental results show that the prediction index RMSE (root mean square error) of the proposed method is only 10-3 magnitude and that of some traditional prediction methods is 10-2 magnitude.Conclusions: Compared with some traditional prediction methods, the proposed method improves the prediction accuracy of ECG signals obviously.
