Abstract

Background
TaCKX wheat gene family members (GFMs) encode the enzyme cytokinin oxidase/dehydrogenase (CKX), which irreversibly degrades cytokinins. The genes are important regulators of cytokinin content and take part in growth and development, with a major impact on yield-related traits. The goal of this research was to test whether these genes might be differentially expressed in the field compared to laboratory conditions and consequently differently affect plant development and yield.

Results
We compared expression and crosstalk of the TaCKX GFMs and TaNAC2-5A gene in modern varieties grown in a growth chamber (GC) and in the field and looked for differences in their impact on yield-related traits. The TaNAC2-5A gene was included in the research since it was expected to play an important role in co-regulation of these genes. The range of relative expression levels of TaCKX GFMs and TaNAC2-5A gene among tested cultivars was from 5 for TaCKX8 to more than 100 for TaCKX9 in the GC and from 6 for TaCKX8 to 275 for TaCKX10 in the field. The range was similar for four of them in the GC, but was much higher for seven others and TaNAC2-5A in the field. The TaCKX GFMs and TaNAC2-5A form co-expression groups, which differ depending on growth conditions. Consequently, the genes also differently regulate yield-related traits in the GC and in the field. TaNAC2-5A took part in negative regulation of tiller number and CKX activity in seedling roots only in controlled GC conditions. Grain number and grain yield were negatively regulated by TaCKX10 in the GC but positively by TaCKX8 and others in the field. Some of the genes, which were expressed in seedling roots, negatively influenced tiller number and positively regulated seedling root weight, CKX activity in the spikes, thousand grain weight (TGW) as well as formation of semi-empty spikes.

Conclusions
We have documented that: 1) natural variation in expression levels of tested genes in both environments is very high, indicating the possibility of selection of beneficial genotypes for breeding purposes, 2) to create a model of an ideotype for breeding, we need to take into consideration the natural environment.

Abstract

Background
Safe, highly curative, short course, direct acting antiviral (DAA) therapies are now available to treat chronic hepatitis C. DAA therapy is freely available to all adults chronically infected with the hepatitis C virus (HCV) in Australia. If left untreated, hepatitis C may lead to progressive hepatic fibrosis, cirrhosis and hepatocellular carcinoma. Australia is committed to eliminating hepatitis as a public health threat by 2030 set by the World Health Organization. However, since the introduction of funded DAA treatment, uptake has been suboptimal. Australia needs improved strategies for testing, treatment uptake and treatment completion to address the persisting hepatitis C public health problem. PLATINUM C is a HCV treatment registry and research platform for assessing the comparative effectiveness of alternative interventions for achieving virological cure.

Methods
PLATINUM C will prospectively enrol people with active HCV infection confirmed by recent detection of HCV ribonucleic acid (RNA) in blood. Those enrolled will agree to allow standardised collection of demographic, lifestyle, treatment, virological outcome and other relevant clinical data to better inform the future management of HCV infection. The primary outcome is virological cure evidenced by sustained virological response (SVR), which is defined as a negative HCV PCR result 6 to 18 months after initial prescription of DAA therapy and no less than 12 weeks after the completion of treatment. Study participants will be invited to opt-in to medication adherence monitoring and quality of life assessments using validated self-reported instruments (EQ-5D-5L).

Discussion
PLATINUM C is a treatment registry and platform for nesting pragmatic trials. Data collected will inform the design, development and implementation of pragmatic trials. The digital infrastructure, study procedures and governing systems established by the registry will allow PLATINUM C to support a wider research platform in the management of hepatitis C in primary care.

Trial registration
The trial is registered with the Australia and New Zealand Clinical Trials Register (ACTRN12619000023156). Date of registration: 10/01/2019.

Abstract

Background and objective
The research on the effect of anesthesia on endovascular therapy (EVT) of acute ischemic stroke is mainly focused on the anterior circulation, and little is known about the data of basilar artery occlusion (BAO). This study aims to investigate the association of anesthesia strategy with 90-day clinical outcomes of patients with acute BAO treated with EVT.

Methods
We reviewed our prospectively collected data from the endovascular treatment database at the Beijing Tiantan Hospital. This included patients with acute BAO who had a documented 90-day modified Rankin Scale (mRS) score from January 2012 to July 2018. Options for EVT included general anesthesia (GA) and conscious sedation (CS) performed by an anesthesia care team in the institution. The recommendation of anesthesia for patients was a joint decision between anesthesiologist and neurointerventionalist according to a pre-designed scheme. Patients who required tracheal intubation for airway protection prior to EVT were excluded. The clinical outcomes we observed were functional independence (mRS ≤2), favorable outcome (mRS ≤3), and mortality at 90 days after the procedure. Univariate and multivariable logistic regression analyses were used to explore the relationship between anesthesia methods and 90-day outcomes.

Results
A total of 187 patients with BAO were treated by EVT in this study. Nine cases requiring emergent intubation prior to EVT were excluded. 139 patients (78.1%) underwent GA and 39 patients (21.9%) underwent CS. In univariate analysis, GA was associated with less functional independence [odds ratio (OR), 0.28; 95% confidence interval (CI), 0.13–0.59] and less favorable outcome (OR, 0.23; 95% CI, 0.10–0.52) than was CS. After adjusting for potential confounders, multivariable analysis showed that there were still significant differences between GA and CS in functional independence (OR, 0.31; 95%CI, 0.10–0.97) and favorable outcome (OR, 0.24; 95%CI, 0.07–0.75).

Conclusion
Our retrospective analysis suggested that the anesthesia strategy may affect outcome, in which general anesthesia may result in less favorable outcomes. Nevertheless, future multicenter randomized controlled trials are needed to confirm our findings.

Abstract

Background
OCT-1 gene is a member of the POU-homeodomain family of transcriptional regulators of B-lymphocyte differentiation by controlling expression of B-cell specific genes. BCL-2 gene is a potent inhibitor of apoptosis and it is essential during B-cell differentiation into germinal center. These genes may be expressed in diffuse large B-cell lymphoma (DLBCL), but the role of BCL-2 in its prognosis has been contradictory, and OCT-1 has yet to be tested.

Methods
In this study, we aimed to investigate the prognostic impact of OCT-1 and BCL-2 expression in DLBCL treated in the real world with immunochemotherapy in a single center. BCL-2 and OCT-1 genes were available in 78.5% (77/98) DLBCL patients, and the RNA for quantitative real-time PCR was isolated from formalin-fixed paraffin-embedded samples. The values obtained for gene expression were transformed in categorical variable according to their median.

Results
Cohort median age was 54.5 years (15–84), 49 (50%) were male, 38/77 (49.4%) and 40/77 (51.9%) presented OCT-1 and BCL-2 expression ≥ median, respectively. The overall response rate (ORR) in all patients was 68.4% (67/98), 65,3% (64/98) of patients acquired complete response, and 3.1% (3/98) partial response, while 6.1% (6/98) were primary refractory. The median follow-up was 3.77 years (95% CI: 3.2–4.1), with 5.43 (95% CI: 2.2-NR) of overall survival (OS) and 5.15 years (95% CI: 2.9-NA) of progression free survival (PFS). OCT-1 ≥ median was associated with shorter OS at univariate analysis (p = 0.013; [HR] 2.450, 95% CI: 1.21–4.96) and PFS (p = 0.019; [HR] 2.270, 95%CI: 1.14–4.51) and BCL-2 gene overexpression presented worse PFS (p = 0.043, [HR] 2.008, 95% CI: 1.02–3.95). At multivariate analysis, OCT-1 overexpression was associated with poor PFS (p = 0.035, [HR] 2.22, 95% CI: 1.06–4.67).

Conclusion
In this study, we showed that overexpression of OCT1 gene was an independent prognostic factor of adverse outcomes in DLBCL.
A scoping review about social and emotional wellbeing programs and services targeting Aboriginal and Torres Strait Islander young people in Australia: understanding the principles guiding promising practice

Published: October 2020

AbstractBackgroundMultiple culturally-oriented programs, services, and frameworks have emerged in recent decades to support the social and emotional wellbeing (SEWB) of Aboriginal and Torres Strait Islander (Aboriginal) people in Australia. Although there are some common elements, principles, and methods, few attempts have been made to integrate them into a set of guidelines for policy and practice settings. This review aims to identify key practices adopted by programs and services that align with the principles of theNational Strategic Framework for Aboriginal and Torres Strait Islander Peoples’ Mental Health and Social and Emotional Wellbeing 2017–2023.MethodsA comprehensive review of electronic databases and organisational websites was conducted to retrieve studies of relevance. Twenty-seven publications were included in the review. Next, we identified promising practices through a collaborative review process. We then used the principles articulated in the above-mentioned framework as the basis to complete a framework analysis. This enabled us to explore the alignment between current scholarship about SEWB programs and services with respect to the principles of the framework.ResultsWe found there was a strong alignment, with selected principles being effectively incorporated into most SEWB program and service delivery contexts. However, only one study incorporated all nine principles, using them as conceptual framework. Additionally, ‘capacity building’, ‘individual skill development’, and ‘development of maladaptive coping mechanisms’ were identified as common factors in SEWB program planning and delivery for Aboriginal people.ConclusionWe argue the selective application of nationally agreed principles in SEWB programs and services, alongside a paucity of scholarship relating to promising practices in young people-oriented SEWB programs and services, are two areas that need the urgent attention of commissioners and service providers tasked with funding, planning, and implementing SEWB programs and services for Aboriginal people. Embedding robust participatory action research and evaluation approaches into the design of such services and programs will help to build the necessary evidence-base to achieve improved SEWB health outcomes among Aboriginal people, particularly young people with severe and complex mental health needs.
Conducting an immersive community-based assessment of post-hurricane experience among Puerto Ricans: lived experience of medical ecology in an environmental disaster and migration
Authors: Vega Ocasio D. , Pérez Ramos J. G. , Dye T. D. V. 
Published: October 2020

Abstract

Background
Two devastating sequential hurricanes impacted Puerto Rico during September of 2017. The hurricanes were traumatic and created social and ecological upheaval throughout Puerto Rico, and subsequently in communities of Central Florida where affected Puerto Ricans migrated. The 2017 hurricane season exposed and exacerbated previous long-standing socio-political, economic, environmental, and health crises, generating a humanitarian emergency in the country. The consequences of these human-ecological disasters destroyed much of Puerto Rico’s residential and environmental infrastructure, displacing thousands of people and resulting in an unprecedented migration to the United States. We report on the lived experience of the investigator team and partnership in conducting community-based formative research subsequent to this disaster, research that aimed to identify salient issues relating to the impact of Hurricanes Irma and María on Puerto Rican communities both in Puerto Rico and in Central Florida.

Discussion
The challenges faced during the conduct of this research include but are not limited to (1) emotional distress of participants and team members, (2) access to affected populations, and (3) precarious environmental factors, such as unstable infrastructure. To address these challenges, the researchers applied a Critical Medical Ecological paradigm along with qualitative methods to assist constructing explanatory models while obtaining internally-valid (from the community perspective), cathartic narrative accounts of the lived experience of hurricane survivors. The experience of the research team may help inform other investigators conducting applied research during a humanitarian crisis.

Conclusion
Lessons learned in this research included: (1) usefulness of applying the Critical Medical Ecological model in the development of the project, (2) incorporating participation and methods that prioritize authenticity, (3) understanding the trauma experience and using study methods sensitive to it, and (4) innovating with best approaches to conduct the study given the challenges in post-hurricane Puerto Rico. These lessons could provide new insights on how to conduct in-depth participatory health research with community members who have been traumatized and – often – displaced. This research also demonstrates the value of pre-existing partnerships, critical consciousness in the field team, and medical ecological modeling as experiential for organizing complex, inter-related, multi-level variables that explain community and individual impact of environmental disasters.

AbstractBackgroundSocial support, defined as the exchange of support in social relationships, plays a vital role in maintaining healthy behavior and mitigating the effects of stressors. This study investigated whether functional aspect of social support is related to 5-year mortality in health checkup participants.MethodsThis study recruited 16,651 subjects (6797 males, 9854 females). Social support was evaluated using five-component questions: Do you have someone 1) whom you can consult when you are in trouble? 2) whom you can consult when your physical condition is not good? 3) who can help you with daily homework? 4) who can take you to hospital when you don’t feel well? and 5) who can take care of you when you are ill in bed? The association between the component of social support and all-cause and cardiovascular mortality was examined using Cox proportional hazard analysis.ResultsThe percentage of subjects without social support components was 7.7–15.0%. They were more likely to be male, non-elderly, and living alone. During the follow-up period, there were 166 all-cause and 38 cardiovascular deaths. Cox proportional analysis adjusted for confounders showed that only the lack of support for transportation to hospital was significantly associated with all-cause (hazard ratio [HR] 2.01, 95% confidence interval [CI] 1.26–3.05) and cardiovascular mortality (HR 3.30, 95% CI 1.41–6.87). These associations were stronger in males than females.ConclusionThis study showed that the lack of social support for transportation to the hospital was independently associated with all-cause and cardiovascular mortality in a community-based population.

Abstract

Background
Patients with urolithiasis have a lower bone mineral density (BMD) than those without stones, suggesting a potential correlation between calcium stone formation and bone resorption disorders, including osteopenia and osteoporosis.

Methods
To investigate the influence of BMD on clinical outcomes in urolithiasis, we performed a single-center retrospective cohort study to analyze patients with urolithiasis who underwent both BMD examination and 24-h urine collection between 2006 and 2015. Data from the national cross-sectional surveillance of the Japanese Society on Urolithiasis Research in 2015 were utilized, and additional data related to urinary tract stones were obtained from medical records. The primary outcome was the development of stone-related symptoms and recurrences during follow-up. A total of 370 patients were included in this 10-year study period.

Results
Half of the patients had recurrent stones, and the two-thirds were symptomatic stone formers. While only 9% of patients had hypercalciuria, 27% and 55% had hyperoxaluria and hypocitraturia, respectively. There was a positive correlation between T-scores and urinary citrate excretion. Both univariate and multivariate analyses demonstrated that female sex was associated with recurrences (odds ratio = 0.44, p = 0.007), whereas a T-score < − 2.5 and hyperoxaluria were associated with symptoms (odds ratio = 2.59, p = 0.037; odds ratio = 0.45, p = 0.01; respectively).

Conclusion
These results revealed that low T-scores might cause symptoms in patients with urolithiasis, suggesting the importance of BMD examination for high-risk Japanese patients with urolithiasis having hypocitraturia.

AbstractBackgroundAccumulating evidence suggests that low vitamin D status may affect male gonadal structure. This study was undertaken to reveal whether vitamin D-deficient rats have demonstrable changes in the quantitative histomorphometric properties of the testis.MethodsIn the present investigation, adult male Sprague-Dawley rats were divided into four groups and received: group 1) conventional diet; group 2) vitamin D-deficient diet; group 3) vitamin D-deficient diet and paricalcitol and group 4) conventional diet plus paricalcitol. After 3 months, serum levels of vitamin D metabolites, Ca, P, LH, FSH, testosterone, and epididymal sperm quality were evaluated. Moreover, the morphometric characteristics of testis were assessed via stereological methods.ResultsRats fed a vitamin D-deficient diet (groups 2 and 3) were normocalcemic and had 25-hydroxyvitamin D3level below 10 ng/mL. A significant reduction in serum testosterone and comparable gonadotropin levels were seen in vitamin D-deficient groups compared to controls. The concentration, morphology, and motility of sperm cells were profoundly disturbed in animals raised on the vitamin D-deficient diet. There was a significant decline in the population of different germ cells, the volume of interstitial tissue and germinal epithelium in group 2 and 3 rats, which were placed on the vitamin D-deficient diet. No appreciable difference in the estimates of the Leydig or Sertoli cell numbers were observed between groups.ConclusionsThe depletion of vitamin D stores and induction of moderate grades of vitamin D deficiency by dietary measures led to remarkable impairment of spermatogenesis and microscopic architecture of rat testis. These findings can be attributed, at least in part, to decreased androgen production.

Published: October 2020

Abstract

Background
Several studies reported that Inter-professional Education (IPE) plays a major role in creating an effective collaborating environment in healthcare settings to achieve high-quality patient care. This study measured the College of Applied Medical Sciences (CAMS) students’ readiness for and perceptions of IPE.

Methods
A cross-sectional study was conducted with 232 undergraduate students in Riyadh, using a stratified random sampling method. All the undergraduate students of CAMS were included. Two previously validated questionnaires, the Interdisciplinary Education Perception Scale (IEPS) and the Readiness for Interprofessional Learning Scale (RIPLS) were used in the study.

Results
The mean score for the RIPLS was 86.8. The Tukey post-hoc test score was significantly higher comparing the Occupational Therapy and the Respiratory Therapy programs. There was no difference between the overall RIPLS and subscales between male and female students as well as senior and junior students. For the IEPS, the mean score was 77.7. The Tukey post-hoc test score was significantly higher in the Occupational Therapy and Respiratory Therapy programs.

Conclusion
The current study indicated that the Applied Medical Sciences’ students demonstrated readiness for IPE as an important element in creating collaborative teamwork in their programs. The early incorporation of IPE in the pre-professional years will enhance collaboration in management and patient care.
