These two horsebean mejus (HMs) exhibited a similar proportion profile for 30 aroma-active compounds. Benzoic acid ethyl ester, 4-ethyl-2-methoxy-phenol and argnine were determined to be characteristic flavor components for NBHM, while 1-(2-furanyl)-ethanone, 2,6-dimethyl-pyrazine, threonine, valine and tyrosine were specific to TCBHM.
Temperature-controlled brewed horsebean meju possessed better physicochemical and flavor characteristics than NBHM. The temperature-controlled brewing technique in CHCP production can be used as a promising alternative to the traditional natural brewing method. © 2020 Society of Chemical Industry.

The aims of this study were to evaluate the diagnostic test features of bedside ultrasonography in pediatric patients with nasal trauma and to investigate whether it is a preferable alternative method to conventional radiography (CR).
Cross-sectional prospective study.
This prospective study was conducted from March 1, 2019, through November 1, 2019. Thirty-one patients under the age of 18 years who had nasal trauma were consecutively included. CR and ultrasonographic imaging tests were investigated in patients with clinical indications for nasal bone fracture. The sensitivity, specificity, and accuracy of ultrasonography and CR were calculated with respect to detecting nasal fractures according to the gold standard method.
Participants were between 3 and 16 years old and the median age was 8 (5-13) years. Nasal bone fracture was clinically detected in 18 patients. While 13 of these fractures were detected with ultrasonography, only 11 were also detected with CR. The sensitivity and specificity of ultrasonography and CR in detecting nasal fractures were 72.2% (95% confidence interval [CI] 46.5-90.3) and 76.9% (95% CI 46.2-95.0) for ultrasonography and 61.1% (95% CI 35.8-82.7) and 69.2% (95% CI 38.6-90.9) for CR.
According to the results of this study, ultrasonography may be used with confidence as a first imaging method in the investigation of nasal fractures, particularly with consideration for avoiding the effects of radiation as much as possible. Our findings point to the next step of conducting trials with a greater number of patients in order to define the diagnostic test features of ultrasonography in pediatric patients.

To identify the incidence and nature of positive findings on imaging studies ordered for evaluation of unilateral vocal fold paralysis (UVFP) of unknown etiology, to analyze these findings based on laterality, and to examine the use of the expanded-field computed tomography (CT) neck protocol in this evaluation.
Retrospective review.
A total of 145 patients from 2000 to 2018 with UVFP of unknown etiology were studied. Data on imaging studies ordered, laterality of paralysis, and significant positive results were studied. An expanded-field CT neck protocol that included the entire course of the vagus and recurrent laryngeal nerves was instituted during the study period.
A total of 20.7% of patients had an etiology for paralysis identified on imaging. Malignancies comprised the majority of findings overall (19/30), whether in the chest (12/18) or the neck (7/12). Etiology was more often found in the chest for left-sided paralysis (15/21) and in the neck for right-sided paralysis (6/9). In 26 patients who underwent both expanded-field CT neck and CT chest, no findings related to the UVFP were seen on CT chest that were not captured by expanded-field CT neck.
This is one of the largest retrospective studies examining the incidence of positive findings on imaging studies for evaluation of UVFP of unknown etiology. Imaging in one of five patients with UVFP of unknown etiology will reveal a causative lesion, most often malignant. Left-sided paralysis tends to localize to the chest, and right-sided paralysis to the neck. Expanded-field CT neck may allow practitioners to forego dedicated CT chest in evaluation of UVFP.

4 Laryngoscope, 2020.The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected millions of people worldwide. Characterization of the immunological mechanisms involved in disease symptomatology and protective response is important to progress in disease control and prevention. Humans evolved by losing the capacity to synthesize the glycan Galα1-3Galβ1-(3)4GlcNAc-R (α-Gal), which resulted in the development of a protective response against pathogenic viruses and other microorganisms containing this modification on membrane proteins mediated by anti-α-Gal immunoglobulin M (IgM)/IgG antibodies produced in response to bacterial microbiota. In addition to anti-α-Gal antibody-mediated pathogen opsonization, this glycan induces various immune mechanisms that have shown protection in animal models against infectious diseases without inflammatory responses. In this study, we hypothesized that the immune response to α-Gal may contribute to the control of COVID-19. To address this hypothesis, we characterized the antibody response to α-Gal in patients at different stages of COVID-19 and in comparison with healthy control individuals. The results showed that while the inflammatory response and the anti-SARS-CoV-2 (Spike) IgG antibody titers increased, reduction in anti-α-Gal IgE, IgM, and IgG antibody titers and alteration of anti-α-Gal antibody isotype composition correlated with COVID-19 severity. The results suggested that the inhibition of the α-Gal-induced immune response may translate into more aggressive viremia and severe disease inflammatory symptoms. These results support the proposal of developing interventions such as probiotics based on commensal bacteria with α-Gal epitopes to modify the microbiota and increase α-Gal-induced protective immune response and reduce severity of COVID-19.
It is well known that duration of pre-drying storage impacts on hop quality. However, little knowledge exists regarding its actual effects on valuable hop components. To investigate these effects, fresh hop cones were stored for 5 or 24 h and dried for 210 min at 65 °C thereafter. Furthermore, to understand the effect of freezing hop cones on the essential oil content, both fresh and stored samples were frozen before and after drying.
The results from gas chromatography analysis show an increase in linalool, β-caryophyllene, humulene, geraniol content and decrease in myrcene content dependent on the period of storage. Total colour difference ΔE values of 4.61 and 5.27 were obtained for fresh and stored hops respectively, indicating discoloration of hops during storage. Modelling of moisture curves revealed the Wang and Singh model to be suitable, with

values of 0.978 and 0.989 and root-mean-square error values of 0.037 and 0.019 for fresh and stored hops respectively.
The results from this study provide an in-depth understanding on the changes occurring within the hop cones both during storage and drying and will further help hop processors optimize their storage times.

To determine the utility of preoperative penetration-aspiration scale (PAS) scores and clinical findings on modified barium swallow (MBS) in predicting advancement of diet after interarytenoid injection augmentation (IAIA).
Retrospective review.
In this retrospective cohort study, 372 consecutive patients who underwent IAIA for pharyngeal dysphagia between 2009 and 2019 were initially identified. Patients were excluded from the study if they had insufficient preop MBS, no postop MBS within 3 months of injection, supraglottoplasty, or underlying neurological condition. Ninety-three patients were included in the study. Pre- and postoperative PAS scores were recorded, as were pre and postop diets. PAS scores were calculated by a single pediatric speech and language pathologist.
Average PAS score on MBS was 5.87 (standard deviation [SD] 2.74); median (range) = 8 (1-8). Postop average was 4.29 (SD 3.02); median (range) = 2 (1-8), P < .001. Those with worse preop PAS scores had increased odds of improvement in diet (odds ratio 1.24, 95% confidence interval [CI] 1.02-1.49, P = .029). An improvement in PAS score of 3.0 or greater predicted an improvement in diet with a sensitivity of 76.7% and a specificity of 85.7%.
PAS score on MBS can be a useful tool when assessing pediatric patients who may be candidates for IAIA. Prospectively comparing PAS score in patients post-IAIA to patients solely undergoing diet modification can help to better objectively assess differences in outcomes and understand the full utility of PAS score.
Level III (Individual Cohort Study) Laryngoscope, 2020.
Level III (Individual Cohort Study) Laryngoscope, 2020.One of the most challenging steps in preparing for dermatologic operations on the scalp can be securing a clean surgical field without long and messy hair. We present a simple and painless way to remove hair from the scalp surgical field utilizing three rubber bands.Implantation of a vagus nerve stimulator (VNS) can be an effective treatment for medically refractory seizures. Laryngeal side effects from a VNS can include hoarseness, cough, and shortness of breath. This report highlights a 5-year-old female who presented with stridor in the setting of acquired laryngomalacia, global developmental delay, and a VNS device. The case demonstrates that a VNS can exacerbate the symptoms of acquired laryngomalacia and that close monitoring of laryngeal side effects is crucial to optimizing care in this population. Laryngoscope, 2020.Variants of tubulin beta 8 class VIII (TUBB8) have been shown to be associated with female infertility characterized by oocyte or embryonic defects. To further investigate the mutational spectrum of TUBB8 and the prevalence of variants, we performed Sanger sequencing of TUBB8 on a total of 115 infertile females who had undergone repeated in vitro fertilization cycles with oocyte or embryonic defects and 200 healthy controls. A total of 31 variants which were absent from the controls were identified in 36 unrelated individuals, accounting for a large proportion of this cohort (31.3%). All of the variants including heterozygous/homozygous missense variants and a heterozygous frameshift insertion variant were at conserved sites and predicted to be deleterious. Besides, these variants had diverse phenotypic effects, including not only oocyte maturation arrest, fertilization failure, and early embryonic arrest, but also multi-pronuclei (MPN) formation, which is a new phenotype associated with TUBB8 variants. Overall, this study reveals a large number of variants of the TUBB8 gene in infertile females with oocyte or embryonic defects. Our results not only broaden the mutational and phenotypic spectra of TUBB8 variants, but also further confirm the critical role of TUBB8 in oocyte maturation, fertilization, and early embryonic development.
