AbstractBackgroundThe purpose of this study was to identify the epidemiologic factors of panfacial fractures (PFs), and to evaluate the significance of anatomic PF categories and the Facial Injury Severity Scale (FISS) in classifying and standardizing panfacial injuries.MethodsA retrospective review of all patients treated with PFs at our institution between June 2010 and April 2021 was performed. PF was defined as a concurrent fracture in at least 3 of 4 facial subunits (frontal, upper midface, lower midface, and mandible). Data regarding patient demographics, causes of injury, location of fractures, major concomitant injuries, and postinjury complications were collected, and the FISS score was collected from each patient. Statistical analysis was performed using IBM SPSS Statistics version 22.0.ResultsA total of 227 patients were enrolled. The most commonly fractured bones were the maxillary sinus wall (92.1%), mandible (82.8%), and zygomatic arch (75.3%), and the most common fracture sites in PFs were graphically presented. Four PF patterns were defined: FULM (n = 60), FUL (n = 39), ULM (n = 127), and FUM (n = 1). There was a significant association between PF patterns and sex (p = 0.018), the number of concomitant injuries (p = 0.014), and early surgical airway management (p = 0.003). Different PF patterns were significantly correlated with different types of concomitant injuries and complications. The FISS score showed a significant difference with PF patterns (p = 0.000) and sex (p = 0.007), and a FISS value of 11 or more is the appropriate cutoff for the prediction of multiple concomitant injuries and complications.ConclusionsBoth the anatomic PF categories and FISS were significantly correlated with various concomitant injuries and complications. The combination of PF categories and FISS provided a better positive and negative prediction of concomitant injuries and complications for PF patients. Patients with FULM and FISS > 11 had an obviously higher proportion of the need for multiprofessional treatment.

AbstractBackgroundData quality assessment is important but complex and task dependent. Identifying suitable measurement methods and reference ranges for assessing their results is challenging. Manually inspecting the measurement results and current data driven approaches for learning which results indicate data quality issues have considerable limitations, e.g. to identify task dependent thresholds for measurement results that indicate data quality issues.ObjectivesTo explore the applicability and potential benefits of a data driven approach to learn task dependent knowledge about suitable measurement methods and assessment of their results. Such knowledge could be useful for others to determine whether a local data stock is suitable for a given task.MethodsWe started by creating artificial data with previously defined data quality issues and applied a set of generic measurement methods on this data (e.g. a method to count the number of values in a certain variable or the mean value of the values). We trained decision trees on exported measurement methods’ results and corresponding outcome data (data that indicated the data’s suitability for a use case). For evaluation, we derived rules for potential measurement methods and reference values from the decision trees and compared these regarding their coverage of the true data quality issues artificially created in the dataset. Three researchers independently derived these rules. One with knowledge about present data quality issues and two without.ResultsOur self-trained decision trees were able to indicate rules for 12 of 19 previously defined data quality issues. Learned knowledge about measurement methods and their assessment was complementary to manual interpretation of measurement methods’ results.ConclusionsOur data driven approach derives sensible knowledge for task dependent data quality assessment and complements other current approaches. Based on labeled measurement methods’ results as training data, our approach successfully suggested applicable rules for checking data quality characteristics that determine whether a dataset is suitable for a given task.
The potential protective role of corticosteroid therapy in patients with asthma and COPD against COVID-19
Authors: Furci Fabiana , Caminati Marco , Senna Gianenrico , Gangemi Sebastiano 
Published: November 2021

Abstract
Background
The observation of patients hospitalized for coronavirus disease (COVID-19) led us to note a lower prevalence of patients affected by chronic respiratory disease, in particular asthmatic patients, compared to the general population. Therefore, the aim of this paper is to evaluate the possible protective role of corticosteroid therapy in patients with chronic lung disease, regarding the risk of contracting severe COVID-19.

Main body
SARS-CoV-2 uses angiotensin-converting enzyme 2 (ACE2) receptors to enter the cells. Considering the high number of these receptors in patients affected by asthma and chronic obstructive pulmonary disease (COPD), the evidence that these patients do not have a high risk of hospitalization for COVID-19 needs further study to understand what the possible protective “factors” are in these patients. In particular, the finding in some studies of reduced coronavirus replication in cell lines treated with steroids, molecules commonly used for treating chronic lung diseases, needs further attention.

Short conclusion
The hypothesis that corticosteroids, commonly used in treating airways diseases, might modify the severity of SARS-CoV-2 disease has become a key point and a possible predictive factor of a positive outcome of COVID-19 in patients treated everyday with these molecules.

Abstract
Background
Recent studies suggest potential benefits of applying L-carnitine in the treatment of cancer cachexia, but the precise mechanisms underlying these benefits remain unknown. This study was conducted to determine the mechanism by which L-carnitine reduces cancer cachexia.

Methods
C2C12 cells were differentiated into myotubes by growing them in DMEM for 24 h (hrs) and then changing the media to DMEM supplemented with 2% horse serum. Differentiated myotubes were treated for 2 h with TNF-α to establish a muscle atrophy cell model. After treated with L-carnitine, protein expression of MuRF1, MaFbx, FOXO3, p-FOXO3a, Akt, p-Akt, p70S6K and p-p70S6K was determined by Western blotting. Then siRNA-Akt was used to determine that L-carnitine ameliorated cancer cachexia via the Akt/FOXO3/MaFbx. In vivo, the cancer cachexia model was established by subcutaneously transplanting CT26 cells into the left flanks of the BALB/c nude mice. After treated with L-carnitine, serum levels of IL-1, IL-6 and TNF-α, and the skeletal muscle content of MuRF1, MaFbx, FOXO3, p-FOXO3a, Akt, p-Akt, p70S6K and p-p70S6K were measured.

Results
L-carnitine increased the gastrocnemius muscle (GM) weight in the CT26-bearing cachexia mouse model and the cross-sectional fiber area of the GM and myotube diameters of C2C12 cells treated with TNF-α. Additionally, L-carnitine reduced the protein expression of MuRF1, MaFbx and FOXO3a, and increased the p-FOXO3a level in vivo and in vitro. Inhibition of Akt, upstream of FOXO3a, reversed the effects of L-carnitine on the FOXO3a/MaFbx pathway and myotube diameters, without affecting FOXO3a/MuRF-1. In addition to regulating the ubiquitination of muscle proteins, L-carnitine also increased the levels of p-p70S6K and p70S6K, which are involved in protein synthesis. Akt inhibition did not reverse the effects of L-carnitine on p70S6K and p-p70S6K. Hence, L-carnitine ameliorated cancer cachexia via the Akt/FOXO3/MaFbx and p70S6K pathways. Moreover, L-carnitine reduced the serum levels of IL-1 and IL-6, factors known to induce cancer cachexia. However, there were minimal effects on TNF-α, another inducer of cachexia, in the in vivo model.

Conclusion
These results revealed a novel mechanism by which L-carnitine protects muscle cells and reduces inflammation related to cancer cachexia.

Authors: Pais Ana Sofia , Reis Sandra , Laranjo Mafalda , Caramelo Francisco , Silva Fátima , Botelho Maria Filomena , Almeida-Santos Teresa 
Published: November 2021

Abstract
Background
Cryopreservation of ovarian tissue is a powerful technique for preserving female fertility, as it can restore fertility and endocrine function. To increase the longevity of the transplant and decrease the risk of reimplantation of neoplastic cells, several studies have been carried out with culture of ovarian tissue. The aim of this study was to compare a conventional (2D) culture with an alginate matrix three-dimensional (3D) model for ovarian tissue culture.

Results
The ovarian tissue culture within the alginate matrix (3D) was similar to 2D culture, regarding follicular density and cell apoptosis in follicles and stroma. The proliferation rate remained stable in both models for follicles, but for stromal cell proliferation it decreased only in 3D culture (p = 0.001). At 24 h of culture, cytotoxicity was lower in the 3D model (p = 0.006). As culture time increased, cytotoxicity seemed similar. Degradation of the tissue was suggested by the histological score analysis of tissue morphology after 72 h of culture. Tissue injury was greater (p = 0.01) in 3D culture due to higher interstitial oedema (p = 0.017) and tissue necrosis (p = 0.035).

Conclusion
According to our results, 3D culture of ovarian tissue has no advantage over 2Dculture; it is more time consuming and difficult to perform and has worse reproducibility.
Resolution of pituitary microadenoma after coronavirus disease 2019: a case report
Authors: Raishan Salah , Alsabri Mohammed , Hanna Ann Mary , Brett Matthew 
Published: November 2021

Abstract
Background
This report describes the case of a patient whose pituitary microadenoma resolved after he contracted coronavirus disease 2019. To our knowledge, this is one of the first reported cases of pituitary tumor resolution due to viral illness. We present this case to further investigate the relationship between inflammatory response and tumor remission.

Case presentation
A 32-year-old man in Yemen presented to the hospital with fever, low blood oxygen saturation, and shortness of breath. The patient was diagnosed with coronavirus disease 2019. Past medical history included pituitary microadenoma that was diagnosed using magnetic resonance imaging and secondary adrenal insufficiency, which was treated with steroids. Due to the severity of coronavirus disease 2019, he was treated with steroids and supportive care. Three months after his initial presentation to the hospital, brain magnetic resonance imaging was performed and compared with past scans. Magnetic resonance imaging revealed changes in the microadenoma, including the disappearance of the hypointense lesion and hyperintense enhancement observed on the previous scan.

Conclusions
Pituitary adenomas rarely undergo spontaneous resolution. Therefore, we hypothesized that tumor resolution was secondary to an immune response to coronavirus disease 2019.

Authors: Dugassa Alemayehu , Alemu Tesfaye , Woldehawariat Yitbarek 
Published: November 2021

Abstract
Background
Emerged faba bean gall disease attacks the stem and leaves of the plant and results in complete crop losses. This study was initiated to screen multi-trait rhizobacteria for their antagonistic efficacy under in-vitro and in-vivo conditions against Olpidium viciae to control the effect of gall disease on faba bean. Sixty antagonistic isolates were first examined for their morphological, biochemical, and phenotypic traits.

Results
Pseudomonas fluorescens AAUPF62, P. aeruginosa AAUS31, Bacillus AAUMF42, and Bacillus AAUAm28 showed greater than 68, 62, 57, and 54% suppression of O. viciae in dual culture, volatile metabolites, culture filtrate assay, and detached leaves experiments, respectively. The in-vivo study revealed that early treatment of the crop with P. aeruginosa AAUS31 reduced severity by 63% (in FB-Obse) and 54% (in FB-26869) faba bean varieties. The co-inoculation of P. fluorescens AAUPF62 and P. aeruginosa AAUS31 significantly enhanced the shoot (P = 0.003; mean = 122 cm) and root (P = 0.018; mean = 94 cm) length, increased shoot dry weight by 8 factors (83 g pot −1), and reduced final disease severity by 92% in FB-Obse variety.

Conclusions
The results revealed that P. fluorescens AAUPF62 and P. aeruginosa AAUS31 strains could be the potential antagonistic agents of gall disease. The use and early treatment of moderately resistant faba bean varieties by co-inoculation of synergistic potential bioagents were recommended.
Fungal genomes: suffering with functional annotation errors
Authors: Mohanta Tapan Kumar , Al-Harrasi Ahmed 
Published: November 2021

Abstract
Background
The genome sequence data of more than 65985 species are publicly available as of October 2021 within the National Center for Biotechnology Information (NCBI) database alone and additional genome sequences are available in other databases and also continue to accumulate at a rapid pace. However, an error-free functional annotation of these genome is essential for the research communities to fully utilize these data in an optimum and efficient manner.

Results
An analysis of proteome sequence data of 689 fungal species (7.15 million protein sequences) was conducted to identify the presence of functional annotation errors. Proteins associated with calcium signaling events, including calcium dependent protein kinases (CDPKs), calmodulins (CaM), calmodulin-like (CML) proteins, WRKY transcription factors, selenoproteins, and proteins associated with the terpene biosynthesis pathway, were targeted in the analysis. Gene associated with CDPKs and selenoproteins are known to be absent in fungal genomes. Our analysis, however, revealed the presence of proteins that were functionally annotated as CDPK proteins. However, InterproScan analysis indicated that none of the protein sequences annotated as “calcium dependent protein kinase” were found to encode calcium binding EF-hands at the regulatory domain. Similarly, none of a protein sequences annotated as a “selenocysteine” were found to contain a Sec (U) amino acid. Proteins annotated as CaM and CMLs also had significant discrepancies. CaM proteins should contain four calcium binding EF-hands, however, a range of 2–4 calcium binding EF-hands were present in the fungal proteins that were annotated as CaM proteins. Similarly, CMLs should possess four calcium binding EF-hands, but some of the CML annotated fungal proteins possessed either three or four calcium binding EF-hands. WRKY transcription factors are characterized by the presence of a WRKY domain and are confined to the plant kingdom. Several fungal proteins, however, were annotated as WRKY transcription factors, even though they did not contain a WRKY domain.

Conclusion
The presence of functional annotation errors in fungal genome and proteome databases is of considerable concern and needs to be addressed in a timely manner.
Effects of Aronia polyphenols on the physico-chemical properties of whey, soy, and pea protein isolate dispersions
Authors: Hansen Mackenzie M. , Hartel Richard W. , Roos Yrjö H. 
Published: November 2021

Abstract
Bioactive compounds including polyphenols (PP) have been observed to naturally form non-covalent complexation interactions with proteins under mild pH and temperature conditions, affecting protein structures and functionality. Previously, addition of Aronia berry PP to liquid dispersions containing whey protein isolate (WPI) and sucrose was found to alter characteristics including viscosity, surface tension, and particle sizes, with changes being attributed to protein-PP interactions. In this study we aimed to investigate whether Aronia PP would interact with soy and pea protein isolates (SPI and PPI, respectively) to a similar extent as with WPI in liquid protein-sucrose-PP mixtures. We hypothesized that formulations containing PPI (comprised of larger proteins) and hydrolyzed SPI (containing more carboxyl groups) may exhibit increased viscosities and decreased aggregate sizes due to enhanced protein-PP interactions. Concentrated liquid dispersions of varied ratios of protein to sucrose contents, containing different protein isolates (WPI, SPI, and PPI), and varied Aronia PP concentrations were formulated, and physical properties were evaluated to elucidate the effects of PP addition. PP addition altered physical characteristics differently depending on the protein isolate used, with changes attributed to protein-PP interactions. SPI and PPI appeared to have higher propensities for PP interactions and exhibited more extensive shifts in physical properties than WPI formulations. These findings may be useful for practical applications such as formulating products containing fruit and proteins to obtain desirable sensory attributes.

Incidence of emerging multidrug-resistant organisms and its impact on the outcome in the pediatric intensive care
Authors: Rezk Ahmed R. , Bawady Somaia Abdelhammed , Omar Nashwa Naguib 
Published: November 2021

Abstract
Background
Healthcare-associated infections (HCAI) are a worldwide threat in intensive care units particularly in the pediatric intensive care units with a major cause of morbidity and mortality among this age group. The aim of the study is to determine the prevalence and risk factors predisposing to multidrug-resistant organisms (MDROs) infections among pediatric intensive care unit (PICU) patients at Ain Shams Pediatric University Hospitals as well as determining mortality and morbidity rates along with the length of stay at PICU.

Results
Culture results revealed that of the 282 patients evaluated, only 26 (9.2%) were MDROs (half of the affected patients had Acinetobacter species (50%) and the rest of them were free, 256 (90.8%). Our study revealed that the majority of MDROs were isolated from sputum in more than half of the patients 19/32 (59.3%) followed by whole blood in 10/32 (31.2%) and urine in 3/32 (9.4%). Pulmonary system was the most common affected site and was mainly colonized by MDR Acinetobacter (71.4%) followed by MDR Klebsiella (41.6%). Regarding MDR risk factors in our PICU, multivariate logistic regression analyses showed significant relationship between MDROs and age under 1 year (odds ratio [OR] 2.4554; 95% confidence interval [95% CI] (1.072–5.625); p = 0.043) and underlying pulmonary disease (OR 2.417; 95% CI (1.014–5.761); p = 0.592). A statistically significant higher mortality was detected in patients colonized with MDROs 9/26 (34.6%) versus MDROs non-colonized patients 32/256 (12.5%) [P=0.002]. Moreover, MDROs infection has negative significant risk with discharged patients ([OR] 0.269; [95% CI] (0.111–0.656); p = 0.002). Additionally, patients infected with MDROs did have significantly greater PICU stay than those non-infected [median (IQR), 16.5 (10.7–22), 5 (4–8), P=0.00] and have longer ventilation [median (IQR), 15.5 (10–18), 3 (2–10), P=0.00].

Conclusion
Prevalence of MDROs (9.2%) was low among PICU cases at Ain Shams University Hospitals. Most common MDROs were Acinetobacter and Klebsiella followed by pseudomonas species. The frequency of gram-negative organisms is much more common than gram-positive organisms. An increasing rate of antimicrobial resistance with increasing mortality and morbidity among PICU patients is observed worldwide; even for new categories, so, strict infection control programs should be implemented.
Mixed cortico-medullary adrenal carcinoma in children: looks are deceptive!!
Authors: Khatri Arti , Mahajan Nidhi , Khan Niyaz Ahmed , Gupta Natasha 
Published: November 2021

Abstract
Background
Mixed cortico-medullary adrenal carcinoma (MCMAC) is an extremely rare entity with scarce literature on its cytomorphology.

Case presentation
A 2-year-old girl presented with abdominal pain for 3 days and a past history of fever with significant weight loss. On examination, a non-tender left hypochondrial firm mass and an enlarged left supraclavicular node were found. Twenty-four-hour urinary levels of VMA were marginally high. Contrast-enhanced computed tomography of the abdomen showed a suprarenal heterogeneous mass encasing major vessels. Aspiration cytology of both mass and node showed similar features comprising a predominant population of singly scattered large cells with moderate cytoplasm, eccentric nucleus and prominent nucleolus in a necrotic background. Tumour cells expressed Synaptophysin and Melan-A. In view of increasing respiratory distress, debulking surgery was performed, and histopathology of the specimen revealed the presence of both malignant medullary and cortical components supported by immunohistochemistry making a final diagnosis of MCMAC. The patient succumbed to death in the postoperative period. The cytology slides were reviewed and were seen to show a dual cell population.

Conclusion
Coexistent malignant cortical and medullary tumour of the adrenal gland is the first case reported in the paediatric age group in the literature with only three previous case reports in adults.
