Authors: Yang Xudong , Tang Jie , Zhao Kejia , Chen Manjun , Tian Yingsong , Chen Xiaobo 
Published: November 2023

Abstract
Purpose
The aim of this study was to elucidate the relationship between clinical characteristics and risk of synchronous lung metastasis (SLM) in patients with extremity soft tissue sarcomas (ESTSLM) at the time of diagnosis and their prognosis.
Methods
Cases from 1975–2018 were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database and demographic, treatments and survival outcomes were analysed.
Results
533 of 7533 patients included in the analysis had SLM. Risk of lung metastasis was high with several variables including male gender, young age, white race, primary site in lower extremity or deep tissues, high differentiation grade, large tumor size, Ewing's sarcoma, rhabdomyosarcoma, and nodal metastasis. The 5 year cancer-specific survival (CSS) rate and median survival of ESTSLM patients was 22.4% and 14 months, respectively. Multivariate analysis showed that older adults, lack of primary site surgery and chemotherapy, and multi-site metastasis including the lungs, were risk factors (p < 0.05). Whereas chemotherapy improved short-term survival compared to survival without chemotherapy (2-year CSS rates of 36.2% vs 26.1%, p < 0.001), there were no survival benefits with metastasectomy (OS, p = 0.286; CSS, p = 0.627).
Conclusions
This is the first comprehensive study that unraveled lung risk factors and prognostic factors affecting metastasis in ESTSLM patients. The findings of this study may be useful for screening and management of patients with ESTSLM.

Published: November 2023

Abstract
Co-circulation of diseases is a public health concern phenomenon as it often informs of population cross-exposure, susceptibility, and cross-protection dynamics. While it commonly occurs, spatial analysis predominately focuses on understanding the individual character of the involved diseases, often neglecting any contributions of co-circulating conditions. This study explores the spatial dynamics and interactions among Zika virus (ZIKV), Dengue virus (DENV), and Chikungunya virus (CHIKV) within the context of co-circulation in the Andean region of Colombia, a tropical and subtropical area highly affected by mosquito-borne diseases. We used Poisson cokriging, a geostatistical method tailored to handle count data (cases), account for the heterogeneous distribution of the population and integrate auxiliary information in the form of count variables. Our results show that Poisson cokriging effectively mitigates the impact of highly variable population densities in the Andean region, producing refined and denoised risk estimates. Likewise, by incorporating information from co-infection, we improved the individual risk estimates and refined the identification of high-risk areas. Our findings show that disease hotspots primarily emerge in municipalities characterized by high rates of co-circulation, coupled with suboptimal water coverage, hygiene conditions, and crowded living environments. We anticipate that the outcomes of this study will contribute to a better understanding of disease co-circulation. In the context of the mosquito-borne disease syndemics in the Andean region, it may offer insights for evidence-based public health strategies.
Conjugating Representations in PGL(k, C) into PGL(k, R)
Authors: Miller Jared 
Published: November 2023

Abstract
The space of representations of a surface group into a given simple Lie group is a very active area of research and is particularly relevant to higher Teichmuller theory. For a closed surface, classical Teichmuller space is a connected component of the moduli space of representations into PSL(2, R) and [Fock-Goncharov:2006] showed that the space of positive representations into PSL(k, R) coincides with the Hitchin component. In this paper we study representations of finitely generated groups into PGL(k, C) and determine necessary and sufficient conditions for such a representation to be conjugate into PGL(k, R). In this way, we identify representations in the larger representation variety which are conjugate in PGL(k, C) to a representation in hom(pi_1 (Sigma), PGL(k, R)) / PGL(k, R).

Published: November 2023

Abstract
Introduction: The novel coronavirus pandemic has taken many people’s lives globally, which has been worse in vulnerable groups. The elderly showed higher mortality rate during the pandemic, compared with other age groups. A Chest Computed Tomography (CT) scan has been implemented as a diagnostic tool in Coronavirus Disease 2019 (COVID-19); however, the mortality increased in the presence of some chest CT scan manifestations.
Materials and methods: This is a retrospective cross-sectional study. 411 COVID-19 patients, aged 60 years and above, analyzing demographic characteristics (age and gender), the severity (ICU admission, non-ICU admission), the outcomes (deceased or recovered), and chest CT scan findings (typical, indeterminate, and atypical) in this population.
Results: 411 patients entered the study; 52.3% females, 47.7% males. The average age of the total population was 73.5± 8.75 years. 19% of the patients were admitted to ICU. 24.8% of the subjects did not survive. 76.1% of subjects showed typical chest CT scan findings of COVID, while 15.6 were indeterminate and in 8.3% atypical. The mortality rate of 60-75 years was 19.8%, and 76-80, and >80 were 34% and 35.4% respectively. Mortality with typical findings was 21.4%, and with indeterminate findings, 28.1%, while with atypical was 50%. Mortality in ICU admitted patients was 78.2%. The frequencies of atypical finding in ICU cases was 15.4%, and in non-ICU cases was 6.6%.
Conclusion: Mortality significantly increased with age and ICU admission. Atypical chest CT scan findings were accompanied by higher mortality and ICU admission that proved their poor prognostic value.

Published: November 2023

Abstract
The mechanical properties of poplar branches are the basis for designing and optimizing the working parameters of branch pruning and crushing machinery. In this paper, a precision microcomputer-controlled electronic universal testing machine was used to test the tensile, compression, bending, and shear mechanical properties of poplar branches. The test results suggested that the elastic constitutive relationship of the stress-strain curves of poplar branches under longitudinal compression, transverse compression, and bending conformed to Hooke's law, and longitudinal tensile and shear exhibited plastic damage; the anti-failure strength, anti-failure elastic modulus and external work of poplar branches under longitudinal compression were greater than those under transverse compression. Meanwhile, the analysis results indicated that there was an exponential function positive correlation between longitudinal tensile strength and longitudinal tensile work, a polynomial exponential function positive correlation between longitudinal compressive strength and longitudinal compressive work, a power function positive correlation between transverse compressive proportional ultimate strength and transverse compressive work, and an exponential function positive correlation between bending strength and bending work; meanwhile, there was a polynomial function positive correlation between the peak shear force and the cross-sectional area of the sample, and there was an exponential function positive correlation between the shear work and the cross-sectional area of the sample. Additionally, the external work required to destroy poplar branches can be estimated using the established regression equation. The study results of this paper provide important data support for poplar branch pruning and crushing simulation tests and machine power selection.

Published: November 2023

Abstract
Background: Surgical site infections (SSI) are among the most common adverse events in the hospital setting. clindamycin is an option to the use of cefazolin, already recommended in the literature although few studies evaluate its effectiveness. due to the increase in cost, since October 2019, cefazolin has been replaced by clindamycin in our hospital. This study aimed to analyze the impact of using clindamycin compared to cefazolin in the prophylaxis of SSI.
Methods: The authors executed a cross-sectional study of patients submitted to surgical procedures with antimicrobial prophylaxis between October 2018 and October 2021. The primary outcome was surgical site infection. Data from medical records included gender, age, type of surgery, surgical specialty, surgery wound, bacteria isolated, surgical complications, hospital readmission, and death. A comparison between means was made by the t-student test. For dichotomous variables, the chi-square was performed.
Results: 12,238 surgical procedures were included, 6,776 with clindamycin and 5,462 with cefazolin. There was no difference in surgical wound classification in both groups. The SSI rate in the group cefazolin was 1.9% (n=104) and 1.2% (n=85) in the group clindamycin [OR 1.65, CI95% 1.19 – 2.15, (p<0.001)]. Staphylococcus aureus was the most common pathogen. Gram-positive cocci were 60% in the group cefazolin and 57% in the group clindamycin. distribution of MRSA was similar between both groups.
Conclusion: Our results demonstrated a lower SSI rate with clindamycin. Despite the retrospective design, we may conclude that clindamycin is a feasible option for cefazolin.

Abstract
The proliferation of social bots on social networks presents significant challenges to network security due to their malicious activities. While graph neural network models have shown promise in detecting social bots, acquiring a large number of high-quality annotated accounts remains challenging, impacting bot detection performance. To address this issue, we introduce BotCL, a social bot detection model that employs contrastive learning through data augmentation. Initially, we build a directed graph based on follower relationships, utilizing semantic, attribute, and structural features of accounts as initial node features. We then simulate account behaviors within the social network and apply two data augmentation techniques to generate multiple views of the directed graph. Subsequently, we encode the generated views using relational graph convolutional networks, achieving maximum homogeneity in node representations by minimizing the contrastive loss. Finally, node labels are predicted using Softmax. The proposed method augments data based on its distribution, showcasing robustness to noise. Extensive experimental results on the Twibot-20 and Twibot-22 datasets demonstrate that our approach surpasses state-of-the-art methods in terms of performance.

Authors: Abza Fantahun 
Published: November 2023

Abstract
Background: Psoriasis is a chronic, inflammatory skin disorder resulting from a genetic predisposition combined with environmental triggers characterized by sharply demarcated erythematosus whitish scaly plaques. May be associated with psoriatic arthritis, metabolic syndrome, and other diseases. The prevalence is about 2% of the world’s population. Two peaks in the age of onset have been reported: Early-onset psoriasis at 20-30 years of age and Late-onset psoriasis at 50-60 years of age & equal in both sexes.
Objectives: This study aimed to assess the magnitude and associated factors of psoriasis from October 2021 to June 2022 at Saint Paul’s Hospital Millennium Medical College Addis Ababa.
Methods: A hospital-based cross-sectional prospective study was conducted from October 2021 to June 2022. A total sample size of 422 patients aged from 11 and above years was included in the study. Then using SPSS version 21.0 The data was entered and analyzed. Descriptive analysis was done to characterize the study participants. Bivariate and multivariable logistic regression was performed to determine the crude and independent predictors of the dependent variable. AOR with 95% CI was used to determine the independent predictors of psoriasis. Statistically, a significant association was considered at a p-value <0.05.
Result: In this study, the magnitude of psoriasis was found to be 6.01% (95% CI:11.6,18.7). Moreover, in the multivariable logistic regression model educational status AOR (95% CI): =0.054, (0.01-0.30). And patients themselves AOR (95%CI): =34.90, (8.27-147.30) stress history were significant predictors of psoriasis.
Conclusion: In this study 6.01% of patients were found to have psoriasis disease. Therefore, the finding needs to give great attention to strengthening national skin disease prevention and control services and implementation of public health policies on awareness, prevention, and treatment of psoriasis patients to keep care of skin and not neglect the disease contact health facility services.
Underlying Mechanisms of Metformin-associated Lactic Acidosis, Visceral Fat, and GERD Progression: A Case Study
Authors: AbuHamdia Abrar , Senaratne Mithum , Singh Priyansha , Shahbaz Tooba 
Published: November 2023

Abstract
Background: Metformin is a routinely prescribed medication for diabetes. Recently, physicians started to prescribe it for a variety of conditions, including polycystic ovarian syndrome (PCOS). It has adverse effects, just like any other medication; lactic acidosis is an uncommon but lethal side effect. The goal of this study was to illustrate the mechanisms of action of metformin in inducing lactic acidosis as well as two undetermined effects, including visceral obesity and the progression of gastroesophageal reflux disease (GERD).
Methods: We present a case of a 23-year-old female with GERD who was treated with metformin for PCOS. We observed the emergence of lactic acidosis symptoms, as well as some unexpected symptoms such as visceral fat, and the advancement of GERD from equilibrium to acute, which lasted for up to a year after stopping metformin.
Results: We found that metformin advanced GERD from an equilibrium to an acute condition in the presence of stress and a history of GERD. Furthermore, gastrointestinal issues have persisted even after a year of discontinuing metformin.
Conclusion: We demonstrated that, despite metformin's powerful effects on the gastrointestinal system, it cannot primarily cause lactic acidosis. Lactic acidosis had developed as a result of metformin interacting with other factors, such as stress and a history of GERD. Our work is the first to capture metformin's connection with GERD; more research is needed to investigate that association and identify the long-term mechanism of metformin, particularly in individuals who have experienced lactic acidosis.

Abstract
Background Tuberculous meningitis (TBM) is an infectious diseases of the central nervous system that are still a global health challenge, including Indonesia. Patients who survive after experiencing TBM have a risk of functional, neurocognitive and psychological disorders that will affect daily activities. The aim of this study is to present a comprehensive review of data on neurocognitive outcome after TBM infection in adults.Method We conducted a systematic literature search to identify studies addressing cognitive outcomes in adult TBM patients. Following a systematic literature search (Pubmed, Scopus, Ebsco), studies underwent duplicate screening by independent reviewers to assess eligibility for inclusion. Three independent reviewers extracted data from included studies.Result Among the article identified, 7 studies met our inclusion criteria, reporting on cognitive outcomes for 364 adults with TBM. All studies followed the patients for 12 months or more. Three studies used Mini-Mental State Examinations (MMSE) to assess cognitive function, while other studies used a variety of tools: HIV-associated neurocognitive disorder (HAND), Montreal Cognitive Assessment (MoCA), neuropsychological (NEUROPSI), and Wechsler Adult Intelligence Scale (WAIS). All studies reported an improvement in cognitive function after completion of TB therapy. Two studies comparing TBM with HIV, and showed TBM patients with HIV had worse cognitive outcomes than those without HIV.Conclusion Cognitive function assessment tools in TBM patients are diverse and after approximately 12 months of follow-up in patients on TB therapy, there was improvement in cognitive function. Standardized reporting of neurocognitive outcomes will be essential to improve data quality and data-sharing potential.
A mathematical model and microcontroller-based method for measuring dielectric permittivity and discharge characteristics with Arduino ATmega 328: a case study in a physics laboratory
Authors: Putra Valentinus Galih Vidia , Ngadiyono  
Published: November 2023

A microcontroller-based measuring instrument and a new mathematical model are used to investigate capacitor permittivity and dielectric materials' charge-discharge characteristics. In this study, a prototype capacitive permittivity measurement apparatus for dielectric materials was carefully developed using an Arduino microcontroller, a resistor, and a capacitor. The experimental setup comprises a capacitor-resistor circuit, wherein a 5-volt power supply sourced from the microcontroller interfaces with a computer. During the charging process, a comprehensive evaluation of model-data alignment was performed, yielding values of 0.54252156, 0.9951, and 111.2508701 for the sum of squares error (SSE), the coefficient of determination (R-squared), and the sum of squares total (SST), respectively. Similarly, the analysis extended to the discharging process, unveiling values of 5.10174756, 0.962805684, and 137.1647082 for SSE, R-squared, and SST, respectively. These findings confirm the accuracy of the microcontroller that was programmed by incorporating a model in precisely measuring the relative permittivity of dielectric materials and capacitance values, with an R-squared value above 0.95 following capacitor literature benchmarks. The novelty of this study is that this configuration enabled the precise assessment of both permittivity and the charge-discharge characteristics of the dielectric materials within the capacitor. This methodology made it possible to accurately measure the permittivity and charge-discharge characteristics of dielectric materials within a capacitor. The scientific significance of this research lies in its ability to provide a carefully developed instrument capable of investigating the permittivity of dielectric materials and capacitor capacitance measurements. Scholars, international engineering communities, and academics can use this technological breakthrough to advance research into dielectric material properties and capacitor characteristics.
