Abstract
Background: Fibrinogen may play an important role in the survival of trauma patients; however, its role in traumatic brain injury (TBI) and its correlation with disease prognosis remain poorly understood. The aims of this study were to determine the incidence of TBI-associated hypofibrinogenemia in patients with TBI and to evaluate the prognostic value of fibrinogen level with respect to mortality and clinical outcomes. Methods: A total of 2570 consecutive TBI patients were retrospectively studied. Prognostic evaluations were determined using the Glasgow Outcome Score (GOS) assessment 3 months after injury. The shape of the relationship between fibrinogen level and mortality or outcome was examined using cubic spline functions. Logistic regression analyses were conducted to identify the association between fibrinogen level and 3-month functional outcomes.Results: Fibrinogen concentrations < 2 g/L were observed in 992 (38.6%) patients at the time of admission. Multivariate analyses showed that for patients with fibrinogen levels < 2.0 g/L, those levels were an independent prognostic factor for 3-month mortality (odds ratio [OR], 0.91; 95% confidence interval [CI], 0.89–0.93; P < .001). By contrast, for patients with fibrinogen levels < 2.5 g/L, the levels were an independent prognostic factor for favorable outcomes at 3 months (OR, 1.654; 95% CI, 1.186–2.306; P = .003). Similar results were also seen for patients with fibrinogen levels > 3.0 g/L, with the levels being an independent prognostic factor for favorable outcomes at 3 months (OR, 0.771; 95% CI, 0.607–0.979; P = .033). Conclusions: Fibrinogen is an independent prognostic factor for clinical outcomes in TBI patients. Maintaining the level of fibrinogen between 2.5 and 3 g/L may improve clinical outcomes in patients with TBI.

Abstract
Background

Zoonotic visceral leishmaniasis by Leishmania infantum is a first order pathology in veterinary clinics of dogs in endemic areas. Moreover, canine infections (CanL) are considered the main reservoir for human disease. Despite the importance of CanL in the control of the diseases within a One Health approach no scientometric study has been published. Aims of the study included the impact of CanL on scientific literature, drugs or combinations used, trends in the period from 2000-2017 and efficacy criteria employed.

Methods

A Web of Science (WOS) based analysis of publications on CanL and chemotherapy of the disease in the period 2000-2017 was carried out using a stepwise methodology. Data were analyzed by year, geographical origin, chemical groups and drugs and efficacy criteria.

Results

Reports on CanL represented a 20% of all publications on leishmaniasis and from these ca. 14% were related to chemotherapy. Publications records on CanL followed the distribution of the infection in endemic areas although an overrepresentation of Mediterranean countries was evident. Published reports on the main antileishmanial drugs used in clinical practice showed a sustained tendency in the period analyzed. Sb V , alone or in combination with allopurinol, represented over 50% of all publications on chemotherapy of CanL despite the availability of more recently marketed drugs.

Conclusions

Chemotherapy of CanL still relies on Sb V and combinations. Reports on chemotherapy are scarce, mostly publicly funded and the variability of experimental conditions make extraordinarily difficult the comparison of efficacy. The vast majority of reports on efficacy do not include any information on supportive therapy; this reduces the actual value of the experiments if intended for the practical management of the disease. Complete reports of the treatments (etiological + symptomatic) would add value to the assays performed.

Abstract
Background: A considerable proportion of patients hospitalized with corona virus disease 2019 (COVID-19) have acquired secondary bacterial infections (SBIs). We report the etiology and antimicrobial resistance of bacteria to provide theoretical basis for appropriate infection therapy.Methods: In the retrospective study, we reviewed electronic medical records of all the patients hospitalized with COVID-19 in the Wuhan Union hospital from January 27 to March 17, 2020. According to the inclusion and exclusion criteria, patients who acquired SBIs were enrolled. Demographic, clinical course, etiology and antimicrobial resistance data of the SBIs were collected. Outcomes were also compared between patients who were classified as severe on admission and those who were classified as critical.Results: 6.8% (102/1495) of the patients with COVID-19 had acquired SBIs and almost half of them (50, 49.0%) died during hospitalization. Compared with the severe patients, the critical patients had a higher chance of SBIs. 159 strains of bacteria were isolated, 85.5% of which were Gram-negative bacteria. The top three bacteria of SBIs were A. baumannii (35.8%), K. pneumoniae (30.8%) and Staphylococcus (8.8%). The isolation rate of carbapenem-resistant A. baumannii and K. pneumoniae were 91.2% and 75.5%, respectively. Meticillin resistance was in 100% of Staphylococcus, and vancomycin resistance was not found. Conclusions: SBIs may occur in patients hospitalized with COVID-19 and lead to high mortality. The incidence of SBIs was associated with the grade on admission. Gram-negative bacteria, especially A. baumannii and K. pneumoniae, were the main bacteria and the resistance rates of the major isolated bacteria were generally high.

Abstract
Background Cytotoxic T-lymphocyte associated protein 4 (CTLA4) inhibitors have been shown to significantly prolong the overall survival (OS) in a wide range of cancers, however, its application is limited due to the therapy response and the prognostic value of CTLA4 in Clear cell renal cell carcinoma (ccRCC), which is the most common and fatal histological subtype in renal cell carcinoma, have not been investigated in detail. Methods In this study, we comprehensively and systematically studied the prognostic value of CTLA4 in ccRCC and its impact on the landscape of tumor-infiltrating lymphocytes (TILs) infiltration and genetic mutation through in vitro experiment and data mining. Results Our results showed that the CTLA4 was up-regulated in both ccRCC tissues and cell lines, and closely related to the disease progression as well as a poor prognosis. Deeper researches demonstrated that CTLA4 regulated the T cell activation and significantly linked to TIL-abundant tumor microenvironment (TME), but companies with an immunosuppressed phenotype, and CTLA4 was associated with more frequent BRCA-associated protein 1 (BAP1) mutation. Furthermore, given the current concerns caused by combined immunotherapy, we also found that CTLA4 was markedly correlated with multiple immune checkpoints, which suggested that ccRCC patients with high expressed CTLA4 may benefit more from immune checkpoint blockades (ICBs) combined therapy.Conclusion CTLA4 had a profound impact on the landscape of TILs and genetic mutation, as well as can be used as the biomarker with high prognosis value.

Abstract
IntroductionLong QT interval (QT) and abnormal QT dispersion (QTd) are associated with sudden death. The relationship between cardiac autonomic neuropathy (CAN) and QT indices in diabetic patients were investigated.MethodsTotally 130 diabetic subjects (mean age 50.87 ± 13.9 years) were included (70 individuals with and 60 individuals without CAN). All participants had sinus cardiac rhythm. The patients who had diseases or take drugs that cause orthostatic hypotension (OH), cardiac arrhythmia and QT prolongation were excluded. After interview and examination, standard and continuous ECG was taken in supine position with deep breathing and standing up position. CAN diagnosis was based on Ewing’s tests. QT, QT corrected (QTc), minimum QT (QT min), maximum QT (QT max) and mean ± SD of QT (QT mean) and QTd were assessed from standard ECG. QTc was calculated by Bazett’s formula. QTc > 440 msec in men and QTc > 0.46 msec in women and QTd > 80 msec were considered abnormal.ResultsIn patients with CAN, 13.7% were symptomatic and 51.2% were asymptomatic. The prevalence of abnormal QTc and QTd was 11.3% and 28.7%, respectively. There was no significant difference between the patients with or without CAN in terms of long QTc and abnormal QTd. However, the mean ± SD of QT max, QT mean and QTd was higher in the patients with CAN (P_Vlue = 0.008, 0.03, 0.02, respectively).ConclusionThe prevalence of asymptomatic CAN was twice that of symptomatic CAN. In patients with CAN the QT max, QT mean and QTd were higher than those without CAN.

Abstract
Objective Few studies have investigated the epidemiology of eating disorders using national representative data. In this study, we investigated the prevalence and economic burden of eating disorders in South Korea.Method The aim of this study was to estimate the disease burden of diagnosed eating disorders (ICD F50.x) over a six-year period between 2010 and 2015, in South Korea. The direct medical cost, direct non-medical costs, and indirect costs resulting from eating disorders were estimated in order to calculate the economic burden of such disorders.Results The total prevalence was 12.02 people (per 100,000) in 2010, and 13.28 in 2015. The economic cost of eating disorders was estimated to be USD5,727,843 in 2010 and USD5,338,752 in 2015. The economic cost and prevalence of eating disorders was the highest in the 20–29 age group.Conclusion The results showed the eating disorders are insufficiently managed in the medical insurance system. The further research is warranted to better understand the economic burdens of each eating disorders.

Abstract
BackgroundNeural stem cells（NSCs）therapy remains one of the most potential approaches for neurological disorders treatment. The discovery of human induced pluripotent stem cells (hiPSCs) and the establishment of hiPSC-derived human neural stem cells (hiNSCs) have revolutionized our technique to cell therapy. Meanwhile, it is often required that NSCs are stored and transported long distances for research or treatment. Although high survival rates could be maintained, conventional methods of cell transport (dry ice or liquid nitrogen) are inconvenient and expensive. Therefore，the establishment of a safe, affordable, and frequent obtained hiPSCs and hiNSCs, with characteristics that match fetal hNSCs and a simple, low-cost way to store and transport, are incredibly urgent. MethodsWe reprogrammed human urinary cells to iPSCs using a virus-free technique and differentiated the iPSCs toward iNSCs/neurospheres and neurons, under Good Manufacturing Practice (GMP)-compatible conditions. The pluripotency of iPSCs and iNSCs was characterized by a series of classical methods (surface markers, karyotype analysis and in vitro and in vivo differentiation capabilities, etc).ResultsHere, our results showed that we successfully generated hiNSCs/neurospheres from more available, non-invasive, and more acceptable urinary cells by a virus-free technique and their differentiation into neural networks. Moreover，hiNSCs survived longer as neurospheres at ambient temperature than those cultured in a monolayer. Approximately 7 days, the neural viability remained at > 80%, while hiNSCs cultured in a monolayer died almost immediately. Neurospheres exposed to ambient temperature that were placed under standard culture conditions (37 ℃, 5% CO2) recovered their typical morphology, and retained their ability to proliferate and differentiate. ConclusionsIn this study, we provided a simple method for the storage of NSCs as neurospheres at ambient temperature as an alternative to more costly and inconvenient traditional methods of cryopreservation. This will enable hiNSCs to be transported over long distances at ambient temperature and facilitate the therapeutic application of NSCs as neurospheres without any further treatment.

Abstract
Background: Patients with rheumatoid arthritis (RA) represent one of the fragile patient groups that might be susceptible to coronavirus disease -19 (COVID-19) and its severe form. On the other side, RA patients have been found not to have an increased risk of COVID19 infection. Moreover, some of the Disease-Modifying Anti-Rheumatic Drugs (DMARDS) commonly used to treat rheumatic diseases like Hydroxychloroquine (HCQ) were proposed as a potential therapy for COVID19 with a lack of full understanding of their molecular mechanisms. This highlights the need for the discovery of common pathways that may link both diseases at the molecular side Methods: We used the in silico approach to investigate the transcriptomic profile of RA synovium compared to osteoarthritis and healthy controls to identify RA specific molecular pathways shared with that of severe acute respiratory syndrome-corona virus-2 (SARS-COV-2) infected lung tissue. Results: Our results showed upregulation of chemotactic factors, including CCL4, CCL8, and CCL11, that all shared CCR5 as their receptor, as a common derangement observed in both diseases; RA and COVID-19. Moreover, our results also highlighted that HCQ might interfere with the COVID-19 infection through its ability to upregulate specific immune cell populations like activated natural killer (NK) cells, besides blocking CCR5 rich immune cell recruitment to the SARS-COV-2 infected lungs Conclusion: Our results might explain some of the reports that showed beneficial effects and indicate the need for proper patients stratification on their immune profile before selecting the therapeutic protocol or clinical trial enrollment.

Published: July 2020

Abstract
Background: The elucidation of pathomechanisms leading to the manifestation of rare (genetically caused) neurological diseases including neuromuscular diseases (NMD) represents an important step toward the understanding of the genesis of the respective disease and might help to define starting points for (new) therapeutic intervention concepts. However, these “discovery studies” are often limited by the availability of human biomaterial. Moreover, given that results of next-generation-sequencing approaches frequently result in the identification of ambiguous variants, testing of their pathogenicity is crucial but also depending on patient-derived material. Results: To systematically address the question if human skin fibroblasts might serve as valuable biomaterial for (molecular) studies of NMD, using proteomic profiling, we generated a protein library by decreasing protein complexity via pH8-based sample fractionation: cataloguing of 8280 proteins revealed the expression of a variety of such linked to genetic forms of motoneuron diseases, congenital myasthenic syndromes, neuropathies and muscle disorders. In silico-based pathway analyses revealed expression of a variety of proteins involved in muscle contraction and such decisive for neuronal function and maintenance suggesting the suitability of human skin fibroblasts to study the etiology of NMD. Based on these findings, next we aimed to further demonstrate the suitability of this in vitro model to study NMD by a use case: utilizing a data independent acquisition approach, the proteomic signature of whole protein extracts of fibroblasts derived from an Allgrove-patient was studied. Paradigmatic dysregulated proteins were confirmed in muscle biopsy of the patient and protein-functions could be linked to neurological symptoms known for this disease. Moreover, protoemic investigation of nuclear protein composition allowed the identification of protein-dysregulations according with structural perturbations observed in the muscle biopsy. As proteomic data suggested a perturbed lipid homeostasis, BODIPY-staining was performed on fibroblasts and coherent anti-stokes Raman scattering microscopy on muscle biopsy. Results of both investigations suggest altered lipid storage as part of the underlying disease-etiology. Conclusions: our combined data reveal that human fibroblasts may serve as an in vitro system to study the molecular etiology of rare neurological diseases exemplified on Allgrove syndrome in an unbiased fashion.

Abstract
Background

Worldwide, the median prevalence of infertility is 9%, but rates in different countries vary from 3.5–16.7%. Infertility, which is defined by the World Health Organization (WHO) as the failure to conceive after 12 months of unprotected regular sexual intercourse, is not considered a medical condition but carries a social stigma and can greatly impact a couple’s self-esteem and wellbeing. There are a number of risk factors associated with infertility such as: genetic background, age, socio-economic factors, and health care including treatment of sexually transmitted diseases. We have achieved the first population-based study on the prevalence of infertility in reproductive aged women in Mongolia, and the factors that influence it.
Method:

We conducted a population-based, cross sectional study in 4 regions of Mongolia and the capital city, Ulaanbaatar: East, West, Central Khangai, Central, and Ulaanbaatar. Our questionnaire consisted of categories that influenced infertility such as: socio-economic status, lifestyle factors, health, reproductive history, present status and sexual function. Trained staff conducted face-to-face interviews with the participants.
Results

A total of 1,920 couples residing in 4 regions of Mongolia and the capital city, Ulaanbaatar were studied. The median prevalence rate was 7.2%, which is similar to the worldwide infertility rate of 9%. Primary and secondary infertility was 2.5% and 5% respectively. Sexual transmitted diseases (STIs) contributed to secondary infertility. Our study showed that the most important risk factors for infertility were rural living and low levels of education. Only 14.8% of infertile patients received hormone therapy, and even fewer infertile patients (0.8%) received in vitro fertilization (IVF) treatment.
Conclusions

Our study shows that two most significant risk factors for infertility were: reliving in rural communities and having a low level of education. Occupational conditions, and monthly household income were not significant risk factors for infertility. Since this is the first population-based study in Mongolia we were not able to measure trends in infertility prevalence but intend to do so in the future.

Abstract
Objective

To explore the clinical efficacy and radioactive results of the bridge-type ROI-C interbody fusion cage (ROI-C) and anterior cervical discectomy and fusion with plating and cage system (ACDF) for cervical spondylopathy.
Methods

From January 2014 to January 2018, 45 patients undergoing ACDF were retrospectively analyzed, including 24 cases of ROI-C (group A) and 21 cases of ACDF (group B). The operation time, blood loss, Neck Disability Index (NDI), Japanese Orthopaedic Association score (JOA), postoperative complications, imaging results including cervical Cobb angle and fusion were compared between groups.
Results

All patients were successfully treated with surgery, and no cerebrospinal fluid leakage, esophageal fistula, or hoarseness occurred after surgery. The operation time and blood loss in group A were lower than those in group B (P < 0.05). During the follow-up period, JOA score increased and NDI score decreased after operation (P < 0.05), but there was no significant difference between the groups (P > 0.05). The incidence of dysphagia in group A was lower than that in group B at 1 month and 3 months after operation (P < 0.05), but the final follow-up results showed that there was no significant difference in the incidence of dysphagia between the two groups (P > 0.05). In group A, the fusion rate was 83.3% 3 months after surgery and 100% at the last follow-up. The rate of adjacent level ossification development was 12.5%. In group B, the fusion rate was 85.7% 3 months after surgery and 100% at the last follow-up. The rate of adjacent level ossification development was 23.8%.
Conclusion

Both ROI-C and ACDF can achieve satisfactory results, but ROI-C has shorter operation time, less bleeding and lower incidence of dysphagia in the short term.
