Abstract
Background
Marfan syndrome is associated with abnormalities in the musculoskeletal system including scoliosis, pectus deformities, protrusio acetabuli, and foot deformities. Over a life span, many patients with Marfan syndrome will need treatment; however, the musculoskeletal morbidity over a life span is not well described. The aim of the present study was to assess the overall burden of musculoskeletal disease in patients with Marfan syndrome.

Materials and methods
A registry-based, nationwide epidemiological study of patients with a Ghent II verified Marfan syndrome diagnosis from 1977 to 2014. Each patient was matched on age, and sex with up to 100 controls from the background population.

Results
We identified 407 patients with Marfan syndrome and 40,700 controls and compared their musculoskeletal diagnoses and surgical treatments using Cox proportional hazards ratio (HR). The risk of a registration of a musculoskeletal diagnosis in patients with Marfan syndrome was significantly increased compared to controls (HR: 1.94 (1.69–2.24). One out of six with Marfan syndrome was registered with scoliosis (HR: 36.7 (27.5–48.9). Scoliosis was more common in women with Marfan syndrome compared to men (HR: 4.30 (1.73–1.08)). One out of 11 were registered with a pectus deformity HR: 40.8 (28.1–59.3), and one out of six with a deformity of the foot. Primarily pes planus (HR: 26.0 (15.2–44.3). The proportion of patients with Marfan syndrome (94/407) that underwent musculoskeletal surgery was also significantly higher (HR: 1.76 (1.43–2.16)). The major areas of surgery were the spine, pectups correction, and surgery of the foot/ankle. Ten patients with Marfan syndrome had elective orthopedic surgery without being recognized and diagnosed with Marfan syndrome until later in life. None of these had scoliosis, pectus deformity or a foot deformity. Among patients with an aortic dissection, the age at dissection was 34.3 years in those with at least one major musculoskeletal abnormality. In patients without a major abnormality the age at dissection was 45.1 years (p < 0.01).

Conclusions
The extent of musculoskeletal disease is quite significant in Marfan syndrome, and many will need corrective surgery during their life span. Surgeons should be aware of undiagnosed patients with Marfan syndrome when treating patients with a Marfan syndrome like-phenotype.

Abstract
Background
As electric bicycles (e-bikes) become increasingly popular, reports of injuries associated with e-bike usage are also rising. Patterns, characteristics, and severity of injuries following e-bike crashes need further investigation, particularly in contrast to injuries from conventional bicycle crashes.

Methods
This prospective observational study included 82 patients treated at a Level II trauma center for injuries resulting from an electric or conventional bicycle crash. Data were collected over one year (05.09.2017–19.09.2018) during in- and outpatient visits. A study-specific case report form was used to identify the bicycle type, cycling behavior (e.g., use of a helmet, safety gear, alcohol), and circumstances of the crash (e.g., road conditions, speed, cause of the incident, time of day, season). Additional information about patient demographics, treatment, and injury characteristics, such as the Injury Severity Score (ISS) and body region injured, were documented. Results were analyzed using chi-square, Fisher’s exact, or Wilcoxon tests. Simple logistic or linear regression models were used to estimate associations.

Results
Of the 82 patients, 56 (67%) were riding a conventional bike and 27 (33%) were using an e-bike. Most incidents were either single-bicycle crashes (66%) or automobile collisions (26%), with no notable difference in prevalence rates between groups. Although a higher proportion of conventional bikers were male (67% vs. 48%), the difference was not significant. E-bikers were older (median 60 years (IQR 44–70) vs. 45 years (IQR 32–62); p = 0.008), were hospitalized more often (48% vs. 24%, p = 0.025), and had worse ISS (median 3 (IQR 2–4) vs. 1 (IQR 1–3), p < 0.001), respectively. Body regions most affected were the extremities (78%) and external/skin (46%), and these were distributed similarly in both groups. Concomitant injury patterns of the thorax/chest with external/skin were higher among e-bikers (p < 0.001). When we controlled for the difference in the median age of the two groups, only the injury severity score of e-bikers remained significantly worse.

Conclusions
Hospitalization and chest trauma rates were higher among e-bikers. After controlling for the older age of this group, the severity of their injuries remained worse than in conventional cyclists. Initial clinical assessments at trauma units should include an evaluation of the thorax/chest, particularly among elderly e-bikers.

Published: March 2022

AbstractThe ultrasonic assisted reverse micelle method (UARM) was used to synthesize Cu-MOF from Cu(NO3)2·3H2O and 2,6-pyridine dicarboxylic acid in a 1:1 molar proportion. It has been characterized using FT-IR, XRD, nitrogen adsorption analysis, SEM and TEM–EDX. The morphology of Cu-MOFs was spherical, with an average particle size distribution of less than 100 nm. Using BET analysis, the surface area of Cu-MOF was found to be 284.94 m2/g. The porous morphology of Cu-MOF was also suggested by SEM and TEM analyses. It has anticancer properties against MCF-7 breast cancer cells. Cytotoxicity testing was performed on MCF-7 breast cancer cells using the MTT cell viability assay, and cell proliferation and viability were found to be approximately 24% higher than the control.

AbstractBackgroundDengue is endemic in the Philippines.Aedes aegyptiis the primary vector. This study aimed to determine the hatching behavior and viability ofAe. aegyptifirst-generation (F1) eggs when exposed to temperature and photoperiod regimes under laboratory conditions.MethodsParental eggs were collected from selected highland and lowland sites in the Philippine big islands (Luzon, Visayas, and Mindanao) during the wet (2017–2018) and dry (2018) seasons. F1 egg cohorts were exposed separately in environmental chambers at 18, 25, and 38 °C with respective photoperiods for 6 weeks. Phenotypes (percent pharate larvae [PPL], hatch rates [HRs], and reproductive outputs [ROs]) were determined.ResultsResults of multivariate analyses of variance (MANOVA) between seasons showed significant main effects of temperature, season, and big island on all phenotypes across all sites. Significant interaction effects between seasons on all phenotypes across sites were shown between or among (1) season and big island, (2) season and temperature, (3) big island and temperature, (4) season, big island, and temperature, (5) big island, altitude, and temperature, and (6) season, big island, altitude, and temperature. Factors associated with the big islands might include their ecology, available breeding sites, and day lengths due to latitudinal differences, although they were not measured in the field. MANOVA results within each season on all phenotypes across sites showed (1) significant main effects of big island and temperature, and (2) significant interaction effects between big island and temperature within the wet season and (3) between temperature and photoperiod within the dry season. PPL were highest at 18 °C and were formed even at 38 °C in both seasons. Pharate larvae might play an adaptive role in global warming, expanded distribution to highlands, and preponderance to transmit human diseases. HRs in both seasons were highest at 25 °C and lowest at 38 °C. ROs were highest at 25 °C in the wet season and at 18 °C in the dry season.ConclusionsTemperature and latitude of Philippine big islands influenced the development-related phenotypes ofAe. aegyptiin both seasons. The two seasons influenced the phenotypes and their interaction effects with big island and/or temperature and/or altitude. Recommendations include year-round enhanced 4S control strategies for mosquito vectors and water pipeline installation in rural highlands.Graphical Abstract

Abstract
Background
The main objective of this study was to determine the prevalence of nine vector-borne pathogens or pathogen genera in roe deer (Capreolus capreolus) in the Netherlands, and to identify which host variables predict vector-borne pathogen presence in roe deer. The host variables examined were the four host factors ‘age category’, ‘sex’, ‘nutritional condition’ and ‘health status’, as well as ‘roe deer density’.

Methods
From December 2009 to September 2010, blood samples of 461 roe deer were collected and analysed by polymerase chain reaction (PCR) for the presence of genetic material from Anaplasma phagocytophilum, Bartonella spp., Babesia spp., Borrelia burgdorferi sensu lato (s.l.), Borrelia miyamotoi, Neoehrlichia mikurensis, Rickettsia spp., and epizootic haemorrhagic disease virus (EHDV), and by commercial enzyme-linked immunosorbent assay (ELISA) for antibodies against bluetongue virus (BTV). The possible associations of host factors and density with pathogen prevalence and co-infection, and in the case of A. phagocytophilum with bacterial load, were assessed using generalized linear modelling.

Results and conclusion
Analysis revealed the following prevalence in roe deer: A. phagocytophilum 77.9%, Bartonella spp. 77.7%, Babesia spp. 17.4%, Rickettsia spp. 3.3%, B. burgdorferi sensu lato 0.2%. Various co-infections were found, of which A. phagocytophilum and Bartonella spp. (49.7% of infected roe deer) and A. phagocytophilum, Bartonella spp. and Babesia spp. (12.2% of infected roe deer) were the most common. Anaplasma phagocytophilum, Babesia spp., and co-infection prevalence were significantly higher in calves than in adult roe deer, whereas the prevalence of Bartonella spp. was lower in roe deer in good nutritional condition than in deer in poor nutritional condition. Local roe deer density was not associated with pathogen presence. The high prevalence of A. phagocytophilum, Bartonella spp., and Babesia spp. is evidence for the role of roe deer as reservoirs for these pathogens. Additionally, the results suggest a supportive role of roe deer in the life-cycle of Rickettsia spp. in the Netherlands.

When venture capitalists are attracted by the experienced
Authors: Kim Dohyeon , Lee Su Yong 
Published: March 2022

AbstractThis article tries to find when the experience plays a key role in investment decisions by venture capitalists (VCs) investment decisions. First, we analyze the relative importance of the decision-making criteria that VCs have in mind. Then, the relationship between uncertainty and entrepreneurs’ experience is investigated. The conjoint analysis and the multiple regression analysis model are applied to sets of hypothetical scenarios to assess the relative importance of the decision-making criteria of the 263 South Korean VCs. VCs generally value entrepreneurs’ education and industry experience in making the investment decision. However, when uncertainty is very high, the newness of the product is high and the completeness of the product is low, VCs focus on entrepreneurs’ managerial experience of entrepreneurs. These findings indicate that environmental uncertainty changes the relative importance of the VC investment criteria. Our research enhances the understanding of how VCs chose to invest, thus helping start-up companies receive VC funding and, ultimately, fostering the growth of high-risk–high-return companies.

Published: March 2022

Abstract
Background
Antineutrophil cytoplasmic antibody-associated vasculitis (AAV) is a group of life-threatening systemic autoimmune diseases. The aim of this study was to determine the relationship between the AAV hub gene and immune cell infiltration, and its value for clinical disease treatment.

Methods
We downloaded the microarray information of 37 AAV patients and 27 controls from Gene Expression Omnibus (GEO). Genes were classified into totally different modules exploitation weighted gene co-expression network analysis (WGCNA). AAV diagnostic indicators were screened and then assessed immune cell infiltration by the least absolute shrinkage and selection operator (LASSO) and CIBERSORT. Finally, Connectivity Map analysis was applied to predict possible AAV glomerulus injury improvement therapies.

Results
WGCNA was developed and differentially expressed genes were classified into 6 modules, the black module was most tightly correlated to AAV. Among them, TIMP1 and FCER1G were most closely related to clinical features. Resting mast cells and monocytes emerged as having the foremost distinguished variations in AAV. C3AR1 and FCER1G were involved in AAV development by immune regulation. Connectivity Map analysis indicated the most significant compound was fisetin.

Conclusions
The present study is that the initial to spot immune cell infiltration with microarray data of glomeruli in AAV, which provides novel proof and clues for additional analysis of the molecular mechanisms.

Published: March 2022

Abstract
Background
Although the total number of microbial taxa on Earth is under debate, it is clear that only a small fraction of these has been cultivated and validly named. Evidently, the inability to culture most bacteria outside of very specific conditions severely limits their characterization and further studies. In the last decade, a major part of the solution to this problem has been the use of metagenome sequencing, whereby the DNA of an entire microbial community is sequenced, followed by the in silico reconstruction of genomes of its novel component species. The large discrepancy between the number of sequenced type strain genomes (around 12,000) and total microbial diversity (106–1012 species) directs these efforts to de novo assembly and binning. Unfortunately, these steps are error-prone and as such, the results have to be intensely scrutinized to avoid publishing incomplete and low-quality genomes.

Results
We developed MAGISTA (metagenome-assembled genome intra-bin statistics assessment), a novel approach to assess metagenome-assembled genome quality that tackles some of the often-neglected drawbacks of current reference gene-based methods. MAGISTA is based on alignment-free distance distributions between contig fragments within metagenomic bins, rather than a set of reference genes. For proper training, a highly complex genomic DNA mock community was needed and constructed by pooling genomic DNA of 227 bacterial strains, specifically selected to obtain a wide variety representing the major phylogenetic lineages of cultivable bacteria.

Conclusions
MAGISTA achieved a 20% reduction in root-mean-square error in comparison to the marker gene approach when tested on publicly available mock metagenomes. Furthermore, our highly complex genomic DNA mock community is a very valuable tool for benchmarking (new) metagenome analysis methods.

Published: March 2022

Objectives: To document improvement in quality of life in patients with Hepatitis-C related cirrhosis after successful eradication of the virus.
Methods: In this observational cohort study conducted at Fatima Memorial Hospital from September 2015 to July 2017, patients with HCV were assessed for improvement in quality of life by using FACIT-F questionnaire. We compared the Quality of life (QOL) score before the start of treatment with DAAs and after achieving SVR12 in various aspects of quality of life including physical, emotional, functional and social well-being.
Results: A total of 71 patients, 52 (73%) were CTP class A, 18 (25%) in B and one (1.4%) in C. The mean score of QOL before AVT was 23.93±7.04 and after achieving SVR it was 36.83±6.36 (P-value <0.001). In the subcategories, score of functional wellbeing, physical well-being and social wellbeing had significantly improved except emotional wellbeing scores. All scores improved across the spectrum of patients in the CTP class A and B. There was only one patient in the CTP-C class.
Conclusion: Chronic HCV infection complicated by cirrhosis causes a significant decline in quality of life. There was a marked improvement in the functional, social and physical health of the patients after eradication of Hepatitis-C with anti-viral therapy except emotional health of the individuals.

Clinical effect of reduning combined with gamma globulin treatment on symptom improvement serum levels of IL-6, 25-(OH)D and LDH in children with severe mycoplasma pneumonia
Authors: Ma Xingna , Gao Wei , An Jinyu 
Published: March 2022

Objectives: To investigate the effects of Reduning combined with gamma globulin on symptom improvement and serum levels of interleukin-6 (IL-6), 25-hydroxyvitamin D[25-(OH)D] and lactate dehydrogenase (LDH) in children with severe mycoplasma pneumonia (MP).
Methods: A total of 123 children with severe MP admitted to the Changzhou Cancer Hospital affiliated to Soochow University from May 2018 to April 2020 were selected as subjects and randomly divided into three groups: control Group-A, control Group-B and the observation group, with 41 cases in each group. Control Group-A was given with Reduning, control Group-B was treated with gamma globulin, while the observation group was treated with Reduning injection combined with gamma globulin. The clinical efficacy, symptom improvement, incidence of adverse reactions, serum levels of IL-6, 25-(OH)D, LDH, Toll-like receptor 4/myeloid differentiation factor 88 (TLR4/MyD88) signaling pathway and T lymphocyte subsets before and after treatment were statistically compared between the three groups.
Results: The total effective rate of treatment in the observation group was higher than that in control Group-A and control Group-B (p<0.05); The time for body temperature, lung rales, and cough to return to normal in the observation group was shorter than that in control Group-A and control Group-B (p<0.05). After treatment, the observation group had lower serum levels of IL-6, LDH, and higher levels of 25-(OH)D compared with control Group-A and control Group-B (p<0.05). Moreover, the observation group had lower serum expressions of TLR4 and MyD88 (p<0.05), higher serum levels of CD4+, CD4+/CD8+, and lower CD8+ compared with control Group-A and control Group-B (p<0.05). No significant difference can be seen in the comparison of the incidence of adverse reactions between the three groups (p>0.05).
Conclusions: Reduning combined with gamma globulin in the treatment of severe MP is worthy of clinical promotion and application. With such a treatment regimen, the immune function of children with severe MP can be significantly enhanced, the inflammatory response can be suppressed, and symptom improvement can be promoted, further improving the treatment outcome.
