Published: October 2019

Abstract
Background : Current evidence of metabolic health benefits of high-intensity interval training (HIIT) are limited to longer training periods or conducted in overweight youth. This study assessed 1) fasting and postprandial insulin and glucose before and after two weeks of HIIT in healthy adolescent boys, and 2) the relationship between pre intervention health outcomes and the effects of the HIIT intervention.
Methods: Seven healthy boys (age:14.3 ± 0.3 y, BMI: 21.6 ± 2.6, 3 participants classified as overweight) completed 6 sessions of HIIT over two weeks. Insulin resistance (IR) and blood glucose and insulin responses to a Mixed Meal Tolerance Test (MMTT) were assessed before (PRE), 20 h and 70 h after (POST) the final HIIT session.
Results: Two weeks of HIIT had no effect on fasting plasma glucose, insulin or IR at 20 h and 70 h POST HIIT, nor insulin and glucose response to MMTT (all P>0.05). There was a strong negative correlation between PRE training IR and change in IR after HIIT (r =-0.96, P <0.05).
Conclusion: Two weeks of HIIT did not elicit improvements to fasting or postprandial glucose or insulin health outcomes in a group of adolescent boys. However the negative correlation between PRE IR and improvements after HIIT suggest that interventions of this type may be effective in adolescents with raised baseline IR.

Abstract
Background : This study was conducted to evaluate and update the current prevalence of and risk factors for chronic kidney disease (CKD) and diabetic kidney disease (DKD) in China.
Methods : A total of 5231 participants were randomly recruited for this study. CKD and DKD were defined according to the combination of the estimated glomerular filtration rate (eGFR) and the presence of albuminuria and diabetes. Participants completed a questionnaire assessing lifestyle and relevant medical history, and blood and urine specimens were taken. Serum creatinine, uric acid, total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein and urinary albumin were assessed. The age- and sex-adjusted prevalence of CKD and DKD was calculated, and risk factors associated with the presence of reduced eGFR, albuminuria, DKD, severity of albuminuria and progression of reduced renal function were analyzed by binary and ordinal logistic regression.
Results : The overall adjusted prevalence of CKD was 16.8% (15.8 – 17.8%) and that of DKD was 3.5% (3.0 – 4.0%). Decreased renal function was detected in 132 participants (2.9%, 95% confidence interval [CI]: 2.5 – 3.2%), whereas albuminuria was found in 858 participants (14.9%, 95% CI: 13.9 – 15.9%). In all participants with diabetes, the prevalence of reduced eGFR was 6.3% (95% CI = 3.9 – 8.6%) and that of albuminuria was 45.3% (95% CI = 40.4 – 50.1%). The overall prevalence of CKD in participants with diabetes was 48.0% (95% CI = 43.1 – 52.9%). The results of the binary and ordinal logistic regression indicated that the factors independently associated with a higher risk of reduced eGFR and albuminuria were older age, sex, smoking, alcohol consumption, overweight, obesity, diabetes, hypertension, dyslipidemia and hyperuricemia.
Conclusions : Our study shows the current prevalence of CKD and DKD in residents of Central China. The high prevalence suggests an urgent need to implement interventions to relieve the high burden of CKD and DKD in China.

Published: October 2019

Abstract
Background

Although it is known that resistant rootstocks facilitate management of fire blight disease, incited by Erwinia amylovora, the role of rootstock root traits in providing systemic defense against E. amylovora is unclear. In this study, the hypothesis that rootstocks of higher root vigor provide higher tolerance to fire blight infection in apples is tested. Several apple scion genotypes grafted onto a single rootstock genotype and non-grafted ‘M.7’ rootstocks of varying root vigor are used to assess phenotypic and molecular relationships between root traits of rootstocks and fire blight susceptibility of apple scion cultivars.Results

It is observed that different root traits display significant (p < 0.05) negative correlations with fire blight susceptibility. In fact, root surface area partially dictates differential levels of fire blight susceptibility of ‘M.7’ rootstocks. Furthermore, contrasting changes in gene expression patterns of diverse molecular pathways accompany observed differences in levels of root-driven fire blight susceptibility. It is noted that a singular co-expression gene network consisting of genes from defense, carbohydrate metabolism, protein kinase activity, oxidation-reduction, and stress response pathways modulates root-dependent fire blight susceptibility in apple. In particular, WRKY75 and UDP-glycotransferase are singled-out as hub genes deserving of further detailed analysis.Conclusions

It is proposed that low root mass may incite resource-limiting conditions to activate carbohydrate metabolic pathways, which reciprocally interact with plant immune system genes to elicit differential levels of fire blight susceptibility.

Published: October 2019

Abstract
Background: Blood stream infections (BSIs) are a major cause of morbidity and mortality. The time from taking blood cultures to obtain results of antibiotic sensitivity can be up to five days which impacts patient care. The Alfred 60 AST™ can reduce laboratory time from positive culture bottle to susceptibility results from 16-25 hours to 5-6 hours, transforming patient care.
Objective: To evaluate the diagnostic accuracy of a rapid antimicrobial susceptibility system, the Alfred 60 AST™, in clinical isolates from patients with BSIs and confirm time to results.
Methods: 301 Gram-negative and 86 Gram-positive isolates were analysed directly from positive blood culture bottles following Gram staining. Antimicrobial susceptibility results and time-to-results obtained by rapid Alfred 60 AST system and BD Phoenix were compared .
Results : A total of 2,196 antimicrobial susceptibility test results (AST) were performed: 1,863 Gram-negative and 333 Gram-positive. AST categorical agreement (CA) for Alfred 60 AST™ was 95% (1772/1863) for Gram-negative and 89% (295/333) for Gram-positive isolates. Gram-negative CA: ampicillin 96% (290/301); ciprofloxacin 95% (283/297); ceftriaxone 96% (75/78); meropenem 97% (288/297); piperacillin-tazobactam 95% (280/295); gentamicin 94% (279/297) and amikacin 93% (277/298). The median time to susceptibility resultsfrom blood culture flagging positive was 6.3 h vs 20 h ( p<0.01 ) for Alfred system vs BD Phoenix™.
Conclusion: Alfred 60 AST system greatly reduced time to antimicrobial susceptibility results in Gram-negative and Gram-positive BSIs with good performance and cost, particularly for Gram-negative bacteraemia.

Abstract
Abstract
Background
Maternal effects contribute to adaptive significance for shaping various phenotypes of many traits. Potential implications of maternal effects are the cause of expression diversity, but these effects on mRNA expression and alternative splicing (AS) have not been fully elucidated in hybrid animal.

Results
Two reciprocal cross hybrids following hybridization of Megalobrama amblycephala (blunt snout bream, BSB) and Culter alburnus (topmouth culter, TC) were used as a model to investigate maternal effects. In a comparison of BSB and TC homoeolog expression from the two reciprocal cross hybrids, we identified 49–347 differentially expressed BSB-homoeologous genes and 54–354 TC-homoeologous genes. 2402, 2959, and 3418 AS events between the two reciprocal cross hybrids were detected in Illumina data of muscle, liver, and gonads, respectively. Moreover, 21,577 (TC-homoeologs) and 30,007 (BSB-homoeologs) AS events were found in the 20,131 homoeologous gene pairs of TBF 3 based on PacBio data, while 30,561 (TC-homoeologs) and 30,305 (BSB-homoeologs) AS events were found in BTF 3 homoeologous gene pairs. These results further improve AS prediction at the homoeolog level. The various AS patterns in bmpr2a with belonged to the bone morphogenetic protein family was selected as an AS model to investigate expression diversity and their potential effects to body shape traits.

Conclusions
The distribution of differentially expressed genes and AS in BSB- and TC-subgenomes exhibited various changes between the two reciprocal cross hybrids, suggesting that maternal effects are the cause of expression diversity. These findings provide a novel insight into mRNA expression changes and AS under maternal effects in lower vertebrates.

Abstract
Abstract Background: Strong artificial and natural selection causes the formation of highly conserved haplotypes that harbor agronomically important genes. GWAS in combination with haplotype analysis has evolved as an effective method to dissect the genetic architecture of complex traits in crop species. Results: We used the 60K Brassica Infinium SNP array to perform a genome-wide analysis of haplotype blocks associated with oleic acid (C18:1) in rapeseed. Six haplotype regions were identified as significantly associated with oleic acid (C18:1) that mapped to chromosomes A02, A07, A08, C01, C02 and C03. Additionally, whole-genome sequencing of 50 rapeseed lines revealed three genes (BnmtACP2-A02, BnABCI13-A02 and BnECI1-A02) in the A02 chromosome haplotype region and two genes (BnFAD8-C02 and BnSDP1-C02) in the C02 chromosome haplotype region that were closely linked to oleic acid content phenotypic variation. Moreover, the co-expression network analysis uncovered candidate genes from these two different haplotype regions with potential regulatory interrelationships with oleic acid content accumulation. Conclusions: Our results suggest that several candidate genes are closely linked, which provides us with an opportunity to develop functional haplotype markers for the improvement of the oleic acid content in rapeseed.

Abstract
Background: The organized sports sector has received increased interest as a setting to stimulate physical activity among inactive target groups. To include many inactive people and to obtain population health benefits, it is important that effective sporting programs are sustained (i.e. continuation of program activities) over a long period of time. This study identified the factors influencing the long-term sustainability of these kind of sporting programs located within local sports clubs in the Netherlands.
Methods: Fourteen Dutch sporting programs aimed at increasing physical activity levels of inactive population groups and funded within the National Action Plan for Sport and Exercise (NAPSE) were the focus of this study. The programs were developed by ten Dutch National Sports Federations (NSFs) and implemented by different sports clubs in the Netherlands within a three-year funded implementation period (2008-2011). This research consisted of semi-structured face-to-face interviews with the program coordinators of the NSFs (n=14) and semi-structured telephone interviews with representatives of sports clubs that provided the programs (n=17 continued the program, n=11 discontinued the program) six and a half years after the funding period ended (November 2017-March 2018). A sustainability framework with five pre-specified main themes (i.e. program design, implementation, trainer/coach, organizational setting, broader community environment) guided data collection and (deductive) thematic analysis.
Results: Ten of the fourteen NAPSE funded sporting programs were sustained at the level of the NSFs. Most factors facilitating (+) and impeding (-) the long-term sustainability of the programs were common to both NSFs and sports clubs, like program adaptation (+) and a lack of program financing (-). Program evaluation (+) and high program costs (-) were specific factors mentioned by NSFs, while factors related to human resources (e.g. lack of volunteers (-)) or the sports club nature (e.g. social aspect in program design (+)) applied to sports clubs. The factors were summarized in the form of a checklist.
Conclusions: Key factors influencing the long-term sustainability of the sporting programs were identified. The results can be used to develop strategies to promote long-term sustainability of these kind of programs and inform funding guidelines in countries with a similar organized sports infrastructure.

Published: October 2019

Abstract
Background The mechanisms underlying the online modulation of motor speech in Parkinson’s disease (PD) have not been determined. Moreover, medical and rehabilitation interventions for PD-associated motor speech disorder (MSD) have a poor long-term prognosis.
Methods To compare risk factors in PD patients with MSD to those without MSD (non-MSD) and determine predictive independent risk factors correlated with the MSD phenotype, we enrolled 314 PD patients, including 250 with and 64 without MSD. We compared demographic, characteristic data, as well as PD-associated evaluations between the MSD group and non-MSD group.
Results Univariate analysis showed that demographic characteristics, including occupation, educational level, monthly income and speaking background; clinical characteristics, including lesions in the frontal and temporal lobes, and concurrent dysphagia; and PD-associated evaluations, including the activity of daily living (ADL) score, non-motor symptoms scale (NMSS) domain 4 score (perceptual problem), and NMSS domain 5 score (attention/memory) were all significantly different between the MSD and non-MSD group (all P < 0.05). Multivariate logistic regression analysis showed that educational level, frontal lesions, and NMSS domain 5 score (attention/memory) were independent risk factors for PD-associated MSD (all P < 0.005).
Conclusions We determined an association between MSD phenotype and cognitive impairment, reflected by low-level education and related clinical profiles. Moreover, attention and memory dysfunction may play key roles in the progression of MSD in PD patients. Further studies are required to detail the mechanism underlying abnormal speech motor modulation in PD patients. Early cognitive intervention may enhance rehabilitation management and motor speech function in patients with PD-associated MSD.

Published: October 2019

Abstract
Background Considering the lack of specific measurement tools to study elders' perceptions in outdoor spaces, the study objectives were to derive and validate a questionnaire that assesses the essential features of elderly-friendly urban spaces. Methods We used closed-ended questions in two phases. In the first qualitative phase, a preliminary questionnaire was defined using grounded theory. In the second phase, the psychometric properties of the elderly-friendly urban spaces were examined through validity and reliability indices. Results The findings of the first phase led to a preliminary item extraction and questionnaire with 15 major domains based on three dimensions: place function, place preferences, and process. In the second phase, a 48-item questionnaire, based on three dimensions, in addition to personal characteristics, was introduced. Conclusions The Elderly-Friendly Urban Spaces Questionnaire (EFUSQ) can be adopted in various communities in understanding of how to create elder-friendly urban spaces to promote active aging.

Abstract
Abstract Background: The purpose of this study is to evaluate a new method for treating obsolete acetabular dislocation with limb discrepancy by external fixation assisted pre-reduction. Methods: Thirteen patients admitted from January 2010 to February 2018 with a mean duration from injury to surgery of 5.0±2.1 months and an average preoperative leg-length discrepancy of 7.7±2.3 cm were enrolled in this study. The dislocation and associated acetabular fracture type, clinical outcomes and residual limb equality were evaluated. Results: All patients were posterior dislocations and nine presented with acetabular fractures and were followed-up at least 12 months. The average traction duration of external fixators was 28.8±8.0 days and all patients received second-stage open reduction and internal fixation. Six patients showed residual limb discrepancy within 2 cm. Patients showed significant improvement in hip function and pain relief. Complications including avascular femoral head necrosis and osteoarthritis occurred in 3 patients. Conclusion: Effective correction of limb discrepancy and improved function showed in patients with obsolete acetabular dislocations and limb equality using traction by external fixation combined with second-stage open reduction. The long-term outcomes need continued follow-up.

Abstract
Background

The presence of urinary fistula after ileal conduit urinary diversion is a challenging complication , and this study investigated the role of the intra-conduit negative pressure system (NPS) in the presence of urinary fistula following ileal conduit (IC) urinary diversion as a conservative treatment.

Methods

Using the intra-conduit NPS, a minor drainage tube was placed within a silicon tube to suck urine from the conduit with consistent negative pressure. Patients with urinary fistula following IC from August 2012 to July 2017 were recorded, and the clinical characteristics and outcome were retrospectively analyzed.

Results

The intra-conduit NPS was used as a primarily conservative treatment for 13 patients who suffered from urinary fistula and presented with a large amount of abdominal/pelvic drainage without other significant morbidities. The median age was 60 years old (42-74 years), and 7 patients were male. The median duration between the IC operation and the presence of urinary fistula was 15 days (2-28 days), and elevated creatinine levels were detected in the abdominal/pelvic drainage with a median level of 2114 µmol/L (636-388 µmol/L). A significant decrease in abdominal/pelvic drainage was identified in 12 patients. The median time that the NPS was used was 9 days (7-11 days). The other patient did not show any improvements after 2 days of observation and then underwent open surgery. With ureteral stenting, 2 abdominal drainage tubes and the intra-conduit NPS were placed during operation, no urine leakage was observed in the abdominal/pelvic field, and the patient was cured in 9 days. With a median follow-up of 22 months, no fistula recurrence or hydronephrosis was detected.

Conclusion

The intra-conduit negative pressure system is a feasible and promising way to cure urinary fistula following ileal conduit urinary diversion. Because this procedure is a mini-invasive and simple approach, it might represent an alternative in selected patients.

Abstract
Abstract Objective –Deficits in the size of the rural medical workforce is an international issue. In Australia, The Rural Clinical School intervention is effective for initial recruitment of rural doctors. However, the extent of retention is not yet established. This paper summarises rural retention over a 10-year period. Methods –Rural Clinical School graduates of STATE NAME were surveyed annually, 2006-2015, and post Graduate Years (PGY) 3-12 included. Survival was described as “tours of service”, where a tour was either a period of ≥1 year, or a period of at ≥2 weeks, working rurally. A tour ended with a rural work gap of ≥52 weeks. Considering each exit from urban as an event, semi-parametric repeated measures survival models were fitted. Results – Of 468 graduates, using the ≥2 weeks definition, 239 PGY3-12 graduates spent at least one tour rurally (average 61.1, CI 52.5 – 69.7 weeks), and a total length of 14,607 weeks. Based on the tour definition of ≥1 year, 120 graduates completed at least one tour (average 1.89, 1.69 – 2.10 years), and a total of 227 years’ rural work. For both definitions, the number of tours increased from one to four by PGY10/11, giving 17,786 total weeks (342 years) across all PGYs for the ≥2 weeks tour definition, and 256 years total for ≥1 year. Significantly more graduates exited from urban work for the 2007-09 middle cohort compared with 2010-11 (HR 1.876, p=0.022), but no significant difference between 2002-06 and 2010-11. Rural origin, age and gender were not statistically significant. Conclusions – PGY3 – 12 RCS graduates contributed substantially to the rural workforce: 51% did so by short rotations, which have not previously been described, while 26% contributed whole years of service. There was an apparent peak in entry and retention for the middle cohort and decline thereafter, likely attributable to lack of rural advanced/specialist vocational training. These data indicate a real commitment to rural practice by RCS graduates, and the need for rural postgraduate vocational training in the rural context as a key element of a successful rural retention strategy.
