Abstract
Background The aim of the present study was to investigate the pathological features of vestibular aqueduct (VA) related high jugular bulb (HJB) and explore the possible cause-consequence relation between HJB and endolymphatic hydrops (EH), and the potential specific radiological signs for screening causative HJB in MD. Methods High-resolution computed tomography (HRCT) and three-dimensional reconstruction (3DRC) were used to detect the anatomical variables associated with VA and jugular bulb (JB) in hydropic and non-hydropic ears. The presence or absence of EH in the inner ear was determined by gadopentetate dimeglumine-enhanced magnetic resonance imaging. Results JB was classified as: Type 1, no bulb; type 2, below the inferior margin of the posterior semicircular canal (PSCC); type 3, between the inferior margin of the PSCC and the inferior margin of the internal auditory canal (IAC); type 4, above the inferior margin of the IAC. There were no significant differences in the presence of types 1, 2 and 3 JB between two groups. The presence of type 4 JB, average height of the JB and prevalence of the non-visualization of the VA in CT scans showed significant differences between two groups. The morphological pattern between the JB and VA revealing by 3DRC was classified as: Type I, the JB was not in contact with the VA; type II, the JB was in contact with the VA, but the latter was intact without obstruction; type III, the VA was obliterated by HJB encroachment. There were no significant differences in the presence of type I and II between two groups. Type III was identified in 5 hydropic ears but no non-hydropic ears, with a significant difference observed between the two groups.Conclusion The present results showed that JB height and non-visualization of the VA on Pöschl's plane could render patients susceptible to the development of EH. A jugular bulb reaching above the inferior margin of the IAC (type 4 JB) could obstruct VA, resulting in EH in a few isolated patients with MD. VA obliteration revealed by 3DRC, as a specific radiological sign, may have the potential for screening causative HJB in MD.

Abstract
BackgroundMaternal admission to the intensive care unit (ICU) during pregnancy or in the postpartum period is a marker of severe acute maternal morbidity. Mechanical ventilation is an important and basic method of maintaining life support in the ICU, but prolonged mechanical ventilation (PMV) is associated with a prolonged length of hospital stay and other adverse outcomes. Therefore, we conducted this retrospective study to describe morbidity and further try to identify the risk factors for PMV in critically ill obstetric women.MethodsThe clinical data were obtained from a single-centre retrospective comparative study of 143 critically ill obstetric patients at a tertiary teaching hospital in mainland China between January 1, 2009, and December 31, 2019. Clinical and obstetric parameters were collected to analyse the risk factors for PMV. Patients were separated into groups with and without PMV. Potential risk factors were identified by univariate testing. Multivariate logistic regression was used to evaluate independent predictors of PMV.ResultsOut of 29,236 hospital deliveries, 265 critically ill obstetric patients entered the ICU. One hundred forty-five (54.7%) of them were treated with mechanical ventilation. Two were excluded because of death within 24 hours. Sixty-five critically ill obstetric patients (45.5%) underwent PMV. The independent risk factors for PMV included estimated blood loss (odds ratio (OR) = 1.296, P = 0.029), acute kidney injury (AKI) (OR = 4.305, P = 0.013), myocardial injury (OR = 4.586, P = 0.012), and PaO2/FiO2 (OR = 0.989, P < 0.001). The area under the receiver operating characteristic (ROC) curve based on the predicted probability of the logistic regression was 0.934.ConclusionsEstimated blood loss, AKI, myocardial injury, and PaO2/FiO2 were independent risk factors for PMV in critically ill obstetric patients.

Abstract
Background
Exercise have shown being effective for managing chronic pain and preventing frailty status in older adults but the effect of an exercise program in the quality of life of pre-frail older adults with chronic pain remains unclear. Our objective was to evaluate the effectiveness of multicomponent structured physical exercise program for pre-frail adults aged 65 years or more with chronic pain to improve their perceived health related quality of life, compared with usual care.
Methods
Open label randomized controlled trial. Participants were community-dwelling pre-frail older adults aged 65 years or older with chronic pain and non-dependent for basic activities of daily living attending a Primary Healthcare Centre. Forty-four participants were randomly allocated to a control group (n = 20) that received usual care or an intervention group (n = 24) that received an 8-week physical activity and education program. Frailty status (SHARE Frailty Index), quality of life (EuroQol-5D-5L), pain intensity (Visual Analogue Scale), physical performance (Short Physical Performance Battery) and depression (Yessavage) were assessed at baseline, after the intervention and after 3 months follow-up. The effect of the intervention was analysed by mean differences between the intervention and control groups.
Results
The follow-up period (3 months) was completed by 32 patients (73%), 17 in the control group and 15 in the intervention group. Most participants were women (78.1%) with a mean age (standard deviation) of 77.2 (5.9) years and a mean pain intensity of 48.1 (24.4) mm. No relevant differences were found between groups at baseline. After the intervention, mean differences in the EuroQol Index Value between control and intervention groups were significant (-0.19 95%CI(-0.33- -0.04)) and remained after three months follow-up (-0.21 95%CI(-0.37- -0.05)). Participants in the exercise group showed better results in pain intensity and frailty after the intervention, and an improvement in physical performance after the intervention and after three months.
Conclusions
An eight-week physical activity and education program for pre-frail older adults with chronic pain, compared with usual care, could be effective to improve quality of life after the intervention and after three-months follow-up.

Abstract
Background: Human T-lymphotropic virus 1 (HTLV-1) is etiologically associated with the chronic inflammatory neurodegenerative disease HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) Annexin A1 (AnxA1) is an anti-inflammatory protein with proposed neuroprotective and anti-neuroinflammatory functions. We hypothesized that ANXA1 gene expression may be dysregulated in HTLV-1-infected HAM/TSP patients. Methods: This study involved 37 individuals infected with HTLV-1, including 21 asymptomatic (AS) carriers and 16 with HAM/TSP, and a control group of 30 individuals negative for HTLV-1 and HTLV-2. For AS HTLV-1-positive and HAM/TSP patients, ANXA1 and formyl peptide receptor (FPR1, FPR2 and FPR3) expression and HTLV-1 proviral load (PVL) in peripheral blood cells were evaluated by real-time quantitative PCR (qPCR), and plasma AnxA1 levels were determined by enzyme-linked immunosorbent assay (ELISA).Results: ANXA1 gene expression was increased in the AS group compared with the HAM/TSP and control groups, but the differences were not statistically significant. FPR1 gene expression was higher in patients with HTLV-1 than in controls (AS, p= 0.0032; HAM/TSP, p< 0.0001). Plasma AnxA1 levels were higher in the AS group than in the HAM/TSP group (p= 0.0045), and PVL was higher in patients with HAM/TSP than in AS individuals (p= 0.0162). The use of a combined ROC curve using Annexin 1 levels and proviral load significantly increased the sensitivity and specificity to predict progression to HAM/TSP (AUC = 0.851 and AUC = 0.937, respectively, to AUC=1,000). Conclusions: Our results suggest that AnxA1 may be dysregulated in HAM/TSP patients. Serological detection of AnxA1 in association with proviral load may provide a prognostic biomarker for HTLV-1-associated neurodegenerative disease.

Published: June 2020

Abstract
Background: Despite the majority humeral shaft nonunions respond well to surgical intervention, a surgeon still encounters a patient with humeral shaft nonunion who had already undergone repeated surgeries for nonunion. This study is a retrospective analysis of the efficacy of the treatment of recalcitrant humeral shaft nonunions using double locking compression plate (LCP) fixation in combination with autogenous iliac crest bone grafting.Methods: A consecutive series of aseptic recalcitrant humeral shaft nonunion underwent surgical treatment between May 2010 and August 2017 in the authors’ institute. Standardized treatment included a thorough debridement, double LCP and screw fixation, and autogenous iliac bone graft. The injury type, the bone affected by nonunion, and the duration of nonunion were recorded for all patients. The main outcome measurements were Constant and Murley scale for shoulder function, Mayo elbow performance index (MEPI) for elbow function and the visual analog scale (VAS) for pain. In addition, all complications were documented.Results: The study consisted of six females and nine males with a mean age of 45.3±13.1 years. Each patient had already undergone at least once failed surgical management for nonunion. The average duration that the bone remained ununited before the index intervention was 126.8±124.2 months. All patients achieved bone union without implant failure. At the final follow-up, both the mean Constant and Murley joint function score and the mean MEPI were significantly improved, and the mean VAS score significantly decreased. Each patient was highly satisfied with the treatment. Complications were only seen in four patents, including one super wound infection, one radial nerve palsy, one ulnar never palsy, and one discomfort at the iliac crest.Conclusion: Double plate fixation combined with autogenous iliac crest bone grafting can result in successful salvage of humerus nonunions in patients who have failed prior surgical interventions.
How Do They Learn: Types and Characteristics of Medical Student Engagement in the Simulation-Based Learning Environment

Published: June 2020

Abstract
Background Student engagement can predict successful learning outcomes and academic development. Expansion of simulation-based medical education will bring about challenges to educators and require them to help medical students to engage themselves in a simulation-based learning environment. Methods We conducted semi-structured interviews with ten medical students to explore their learning types and characteristics in the simulation-based learning environment. The interpretative phenomenological methods were used to analyze the data. Results The interviews were thematically analyzed to form three types of student engagement in the simulation-based learning environment: reflective engagement, performance engagement, and interactive engagement. The analysis also identified eight sub-themes: active, persistent, and focused thinking engagement; problem-oriented thinking engagement; active “voice” in class; strong emotional experience and disclosure; demonstration of professional leadership; interaction with realistic learning situations; support from teammates; and friendship-like lecturer-student interaction.Conclusions The findings explain the mechanisms behind student engagement in the simulation-based learning environment from two perspectives: the two-way construction of individuality and space in learning along with the interdependence of the learner and the learning community. That is, expanding the learning space centering around “inquiry” helps strengthen reflective communication and dialogue. It also facilitates imagination, stimulates empathy, and builds an inter-professional learning community. In this way, medical students are expected to learn from the two-way transmission of information, cultivate and reshape the interpersonal relationship, so as to improve engagement in the simulation-based learning environment.

Abstract
Background: Animal temperament is defined as the consistent behavioural and physiological differences that are seen between individuals in response to the same stressor. Neurotransmitter systems, like serotonin and oxytocin in the central nervous system, underlie the variation in temperament in humans. The variations like single nucleotide polymorphisms (SNPs) in the genes for tryptophan 5-hydroxylase (TPH2), the serotonin transporter (SLC6A4), the serotonin receptor (HTR2A), or the oxytocin receptor (OXTR) are associated with the behavior phenotypes in human. Thus, the objective of this study was to identify SNPs in TPH2, SLC6A4, HTR2A and OXTR and to test if those variations predict the temperament of Merino sheep. Results: Using ewes from the UWA temperament flock, that has been selected on emotional reactivity for more than 20 generations, eight SNPs (rs107856757, rs107856818, rs107856856 and rs107857156 in TPH2, rs20917091 in SLC6A4, rs17196799 and rs17193181 in HTR2A, and rs17664565 in OXTR) were found to be distributed differently between calm and nervous sheep. These eight SNPs were then genotyped in 260 sheep from a non-selected flock that has never been selected on emotion reactivity, followed by the estimation of the behavioural traits of those 260 sheep using an arena test and an isolation box test. We found that several SNPs in TPH2 (rs107856757, rs107856818, rs107856856 and rs107857156) were in strong linkage disequilibrium, and all were associated with behavioural phenotype in the non-selected sheep. Similarly, rs17196799 in HTR2A was also associated with the behavioural phenotype. Conclusions: We thus conclude that, rs107856856 and rs17196799 could be used as gene markers for the temperament of Merino sheep, with allele C of rs107856856 and allele A of rs17196799 being associated with calm temperament.
Flexibility and resilience of Great tit (Parus major) gut microbiomes to changing diets

Published: June 2020

Abstract
Background: Gut microbial communities play important roles in nutrient management and can change in response to host diets. The extent of this flexibility and the concomitant resilience is largely unknown in wild animals. To begin untangling the dynamics of avian-gut microbiome symbiosis associated with diet changes, we exposed Parus major (Great tits) fed with a standard diet (seeds and mealworms) to either a mixed (seeds, mealworms and fruits), a seed, or a mealworm diet for four weeks, and examined the flexibility of gut microbiomes to these compositionally different diets. To assess microbiome resilience (recovery potential), all individuals were subsequently reversed to a standard diet for another four weeks. Cloacal microbiomes were collected weekly and characterised through sequencing the v4 region of the 16S rRNA gene using Illumina MiSeq. Results: Initial microbiomes changed significantly with the diet manipulation but the communities did not differ significantly between the three diet groups (mixed, seed and mealworm), despite multiple diet-specific changes of specific bacterial genera. Reverting birds to the standard diet led to only a partial recovery in gut community compositions. The majority of the bacterial taxa that increased significantly during diet manipulation decreased in relative abundances after reversion to the standard diet; however, bacterial taxa that decreased during the manipulation rarely increased after diet reversal.Conclusions: The gut microbial response and partial resilience to dietary changes support that gut bacterial communities of P. major play a role in accommodating dietary changes experienced by wild avian hosts. This may be a contributing factor to the relaxed association between microbiome composition and bird phylogeny. Our findings further imply that interpretations of wild bird gut microbiome analyses from single-time point sampling, especially for omnivorous species or species that have changing seasonal diets, should be done with caution. The partial community recovery implies that ecologically relevant diet changes (e.g., seasonality and migration) open up gut niches that may be filled by previously abundant microbes or replaced by different symbiont lineages, which has important implications for the integrity and specificity of long-term avian-symbiont associations.

Abstract
BACKGROUND: Anemia is associated with high morbidity and mortality in older people. However, anemia in older individuals is not fully understood, and national data on the prevalence and characteristics of anemia in Korean older people are lacking. This study aimed to evaluate the prevalence and characteristics of anemia in older adults using data from the Korea National Health and Nutrition Examination Survey (KNHANES) , which is the nation-wide cross-sectional epidemiological study conducted by Korean Ministry of Health and Welfare.Methods: Data from the total of 62,825 participants of the 2007-2016 KNHANES were merged and analyzed to investigate differences in participant characteristics and potential risk factors for anemia.RESULTS: The prevalence of anemia was higher in the population aged ≥65 years (older adults) than in the younger population. Anemia was also more prevalent among females than among males, but the difference was not statistically significant in people aged >85 years. Being underweight, receiving a social allowance, living alone, and having comorbidities such as hypertension, arthritis, diabetes mellitus (DM), cardiovascular disease (CVD), stroke, cancer, and chronic renal failure (CRF) were more prevalent in older adults with anemia than in the group without anemia. In the univariate and multivariate analyses, older age, female sex, underweight, and comorbidities including arthritis, DM, CVD, stroke, cancer, and CRF were associated with an increased risk of anemia. Furthermore, the prevalence data were significantly higher in this study than in previous studies.CONCLUSIONS: This study revealed that age, female sex, underweight, and the presence of comorbidities such as arthritis, DM, CVD, stroke, cancer, and CRF were associated with an increased risk of anemia in Korean older adults. Our findings may be useful in developing interventions and programs aimed at healthy aging. Further study on causal relationships between anemia and other variables in the older population is necessary.Trial registration: KNHANES was approved by the KCDC Research Ethics Review Committee annually since 2007(2007-02CON-04-P, 2008-05EXP-01-C, 2009-01CON-03-2C, 2010-02CON-21-C, 2011-02CON-06-C, 2012-01EXP-01-2C, 2013-07CON-03-4C, 2013-12EXP-03-5C, 2015-01-02-6C). Ethical approval of this study was obtained through the Institutional Review Board of Dong-A University Hospital (DAUHIRB-EXP-20-035).

Abstract
Objectives: Physical activity in children and adolescents has positive effects on cardiopulmonary functions in this age-group as well as later in life. As poor cardiopulmonary function is associated with higher mortality and morbidity in later life, increasing physical activity especially in children needs to become a priority. Trampoline jumping is widely appreciated in children, the objective was to investigate its use as a possible training modality.Methods: 15 healthy children (10 boys and 5 girls) aged 8.8 years undertook an incremental running step test outdoors using a mobile cardiopulmonary exercise testing unit. After a rest period of at least two weeks a trampoline test using the mobile unit was realized by all participants including a 5-minute endurance interval with moderate jumping and two high-intensity intervals with vigorous jumping for 2 minutes, interspersed with 1 minute rests.Results: During the endurance interval the children achieved B-values slightly higher than VT1 and during the high-intensity interval comparable to VT2 of the running test. They were able to maintain these values for the duration of the respective intervals. The maximum values recorded during the trampoline test were significantly higher than during the incremental running test.Conclusion: Trampoline jumping is an adequate tool for implementing high-intensity interval training as well as moderate-intensity continuous training in children. As it is a readily available training device and is greatly enjoyed in this age-group this could represent a means for increasing physical activity in children.
