Abstract
Background: High temperatures, particularly at night, decrease rice yield and quality. As high nighttime temperatures (HNTs) become increasingly frequent due to climate change, it is imperative to develop rice crops that tolerate HNTs. DNA methylation may represent a potential avenue for HNT-tolerant rice strain development, as this mechanism regulates gene activity and cellular phenotype in response to adverse environmental conditions without changing the nucleotide sequence.Results: After HNT exposure, the methylation patterns of cytosines in the CHH context differed noticeably between two coisogenic rice strains with significantly different levels in heat tolerance. Methylation differences between strains were primarily observed on successive cytosines in the promoter or downstream regions of transcription factors and transposon elements. In contrast to the heat-sensitive rice strain, the regions 358–359 bp and 2–60 bp downstream of two basal transcriptional factors (TFIID subunit 11 and mediator of RNA polymerase II transcription subunit 31, respectively) were fully demethylated in the heat-tolerant strain after HNT exposure. In the heat-tolerant strain, HNTs reversed the methylation patterns of successive cytosines in the promoter regions of various genes involved in abscisic acid (ABA)-related reactive oxygen species (ROS) equilibrium pathways, including the pentatricopeptide repeat domain gene PPR (LOC_Os07g28900) and the homeobox domain gene homeobox (LOC_Os01g19694). Indeed, PRR expression was inhibited in heat-sensitive rice strains, and the methylation rates of the cytosines in the promoter region of PRR were greater in heat-sensitive strains as compared to heat-tolerant strains.Conclusions: After HNT exposure, cytosines in the CHH context were more likely than cytosines in other contexts to be methylated differently between the heat-sensitive and heat-tolerant rice strains. Methylation in the promoter regions of the genes associated with ABA-related oxidation and ROS scavenging improved heat tolerance in rice. Our results help to clarify the molecular mechanisms underlying rice heat tolerance.

Abstract
Background: To calculate and evaluate the prevalence of reduced uncorrected distant visual acuity (UCDVA) in primary, middle and high schools in 6 districts of Changsha, Hunan, China. Methods: A population-based retrospective study was conducted in 239 schools in 6 districts of Changsha. After routine eye examination to rule out diseases that can affect refraction, 250,980 eligible students from primary, middle and high schools were enrolled in the survey. Then the uncorrected distant and near visual acuity of each eye were measured. Categories of schools, districts, grades, eye exercises and sports time were also documented and analyzed. Results: The overall prevalence of reduced UCDVA was 51.8% (95% confidence interval [CI]: 51.6%-52.0%) in 6 districts of Changsha. Results of individual districts were as follows: Furong district 59.9%(95% CI: 57.9%-61.8%), Tianxin district 62.3%(95% CI: 60.5%-64.0%), Wangcheng district 47.8%(95% CI: 46.8%-48.8%), Kaifu district 58.5%(95% CI: 58.0%-58.9%), Yuhua district 47.0%(95% CI: 46.7%-47.4%) and Yuelu district 52.6%(95% CI: 52.3%-52.9%). The proportion of normal VA is seen to decrease from primary grade 3. The proportion of mildly reduced UCDVA is higher in primary grade 1 and 2. The proportion of moderately reduced UCDVA remains similar during 12 grades. The proportion of severely reduced UCDVA increases with grades. Multivariate analysis shows that the prevalence of reduced UCDVA is higher in key schools (risk ratio [RR]= 1.47, 95% CI 1.44-1.50) than non-key schools. Conclusions: According to the existing data analysis results, the prevalence of reduced UCDVA among primary, middle and high school students in Changsha is very high. Some effective measures need to be taken to prevent it.

Published: July 2020

Abstract
Background: There is growing interest in examining the factors affecting the reporting of errors by nurses. However, little research has been conducted into the effects of perceived patient safety culture and leader coaching of nurses on the intention to report errors.Methods: This cross-sectional study was conducted amongst 256 nurses in the emergency departments of 18 public and private hospitals in Tabriz, northwest Iran. Participants completed the Hospital Survey on Patient Safety Culture (HSOPSC), Coaching Behavior Scale and Intention to Report Errors questionnaires and the data was analyzed using multiple linear regression analysis.Results: Overall, 43% of nurses had an intention to report errors; 50% of respondents reported that their nursing managers demonstrated high levels of coaching. With regard to patient safety culture, areas of strength and weakness were “teamwork within units” (PRR = 66.80%) and “non-punitive response errors” (PRR = 19.66%). Regression analysis findings highlighted a significant association between an intention to report errors and patient safety culture (B=0.123, CI 95%: 0.005 to 0.328, P = 0.026), leader coaching behavior (B=0.172, CI 95%: 0.066 to 0.347, P = 0.004) and nurses’ educational status (B=0. 787, 95% CI: -.064 to 1.638, P = 0.048). Conclusions: Further research is needed to assess how interventions addressing patient safety culture and leader coaching behaviors might increase the intention to report errors.

Abstract
Background : The death of a child at the emergency ward is one of the most difficult problems that the clinicians of these wards have to deal with. In our country the published data concerning the causes and the factors related to pediatric mortality especially in the pediatric emergency wards is very rare. This study aimed to study the epidemiology of the pediatric mortality in the pediatric emergency department (PED), to determine its rate and identify its most frequent causes. Methods : It is a retrospective and descriptive study, over five years (1st January 2012 and 31st December 2016) including all children aged from 0 to 15 years old who died at the PED in the Mohamed VI Hospital in Marrakech. Results : During the period of the study a total of 172.691 patients presented to the PED, among which 628 died (pediatric mortality rate : 3.63%). The masculine gender was predominant (n=383) with a gender ratio of 1.59. Two-thirds of the patients died in the first 24 hours (n=421). The median of time from admission to death was around 12 hours. Majority of the deceased children (n=471, 75%) were from a low socioeconomic status. The most frequent cause of admissions for deceased patients in the PED was respiratory distress (n=296, 47%) followed by neurological disorders (n=70, 11%). Neonatal mortality (≤ 1 month of age) was predominant (n=472, 75.1%), followed by postnatal mortality (1 month to 1 year old) (n=73, 11.6%). The most frequent causes of pediatric mortality, whatever the age range, were dominated by neonatal pathologies (n=391, 62.3%), followed by infecious causes bronchopulmonary infections included (n=49, 7.7%), birth deformities (n=46, 7.3%) while traumas were merely at 0.9% (n=6). The most frequent causes of neonatal mortality were neonatal infections (n=152, 32.2%), prematurity (n=115, 24.4%), perinatal asphyxia (n=71,15%) and neonatal respiratory distress (n=57, 12.1%). Conclusion : Our data once again underline the crucial importance of prevention. This requires correct follow-up of the pregnancies, an adequate assistance of births, and perfecting healthcare provision to newborns in order to attain proper assistance.

Abstract
Background: Although the WHO Trial Registration Data Set (TRDS) has been published for many years, the quality of clinical trial registrations with traditional Chinese medicine (TCM) is still not satisfactory, especially about the inadequate reporting on TCM interventions. The development of the WHO TRDS for TCM Extension 2020 (WHO TRDS-TCM 2020) aims to address this inadequacy. Methods: A group of clinical experts, methodologists, epidemiologists, and editors has developed this WHO TRDS-TCM 2020 through a comprehensive process, including the baseline survey, draft of the initial items, three-round of Delphi survey, solicitation of comments, revision, and finalization. Results: The WHO TRDS-TCM 2020 statement extends the latest version (V.1.3.1) of TRDS published in November 2017. The checklist includes 11 extended items (including subitems), namely Source(s) of Monetary or Material Support (Item 4), Scientific Title (Item 10a and 10b), Countries of Recruitment (Item 11), Health Condition(s) or Problem(s) Studied (Item 12), Intervention(s) (Item 13a, 13b and 13c), Key Inclusion and Exclusion Criteria (Item 14), Primary and Key Secondary Outcomes (Item 19 to 20), and Lay Summary (Item B1). For Item 13 (Interventions), three common TCM interventions--i.e., Chinese herbal medicine formulas, acupuncture and moxibustion—are elaborated. Conclusions: The group hopes that the WHO TRDS-TCM 2020 can improve the reporting quality and transparency of TCM trial registrations, assist registries in assessing the registration quality of TCM trials, and help readers understand TCM trial design.Trial registration: Not applicable.

Published: July 2020

Abstract
Background: The shortage of health workers is a global phenomenon. To meet increasing patient demands on UK health services, providers are increasingly relying on temporary staff to fill permanent posts. This study examines the occurrence of ‘care left undone’, understaffing and temporary staffing across acute sector settings. Methods: “Secondary data analysis from an RCN administered online survey covering nurses from hospitals and trusts across all four UK countries. Staffing and ‘care left undone’ measures were derived from the responses of 8,841 registered nurses across the UK. A locally smoothed scatterplot smoothing regression analysis (Loess) was used to model the relationship between any ‘care left undone’ events and full complement, modest and severely understaffed shifts, and proportions of temporary staff. Results: Occurrence of ‘care left undone’ was highest in Emergency Departments (48.4%) and lowest in Theatre settings (21%). The odds of ‘care left undone’ increase with increasing proportion of temporary staff. This trend is the same in all understaffing categories. On shifts with a full quota of nursing staff, an increase in the proportion of temporary staff from 0 to 10 per cent increases the odds of care left undone by 6 per cent (OR= 1.06, 95 % CI, 1.04-1.09). Within the full quota staffing category, the difference becomes statistically significant (p<0.05) on shifts with a proportion of temporary nursing staff of 40 per cent or more. On shifts with a full quota of nursing staff the odds of a ‘care left undone’ event is 10 per cent more with the proportion of temporary nursing staff at 50 per cent, compared to shifts with modest understaffing of 25 per cent or less with no temporary nursing staff (OR=1.1, 95%CI, 0.96-1.25). Conclusion: The odds of a ‘care left undone’ event are similar for fully staffed shifts with a high temporary nursing staff ratio compared to severely understaffed shifts with no temporary nursing staff. Increasing the proportion of temporary nurse staff is associated with higher rates of self-reported care left undone by nursing staff. This has significant implications for nurse managers and policy makers.

Authors: Liu Yongping , Wu Xue , Xia Xi , Yao Jun , Wang Bao-jie 
Published: July 2020

Abstract
Background: The CACNA1C gene was defined as a risk gene for schizophrenia in a large genome-wide association study of European ancestry performed by the Psychiatric Genomics Consortium. Previous meta-analyses focused on the association between the CACNA1C gene rs1006737 and schizophrenia. The present study focused on whether there was an ancestral difference in the effect of the CACNA1C gene rs1006737 on schizophrenia. rs2007044 and rs4765905 were analyzed for their effect on the risk of schizophrenia. Methods: Pooled, subgroup, sensitivity, and publication bias analysis were conducted.Results: A total of 18 studies met the inclusion criteria, including fourteen rs1006737 studies (15,213 cases, 19,412 controls), three rs2007044 studies (6,007 cases, 6,518 controls), and two rs4765905 studies (2,435 cases, 2,639 controls). An allele model study also related rs2007044 and rs4765905 to schizophrenia. The overall meta-analysis for rs1006737, which included the allele contrast, dominant, recessive, codominance, and complete overdominance models, showed significant differences between rs1006737 and schizophrenia. However, the ancestral-based subgroup analysis for rs1006737 found that the genotypes GG and GG + GA were only protective factors for schizophrenia in Europeans. In contrast, the rs1006737 GA genotype only reduced the risk of schizophrenia in Asians. Conclusions: Rs1006737, rs2007044, and rs4765905 of the CACNA1C gene were associated with susceptibility to schizophrenia. However, the influence model for rs1006737 on schizophrenia in Asians and Europeans demonstrated both similarities and differences between the two ancestors.

Abstract
Neutrophils are the most abundant white blood cells in the human body responsible for fighting viral, bacterial and fungi infections. Out of the 100 billion neutrophils produced daily, it is estimated that 10 % of these cells end up in oral biofluids. Because saliva is a fluid accessible through non-invasive techniques, it is an optimal source of cells and molecule surveillance in health and disease. While neutrophils are abundant in saliva, scientific advancements in neutrophil biology have been hampered likely due to their short life span, inability to divide once terminally differentiated, sensitivity to physical stress, and low RNA content. Here, we devise a protocol aiming to understand neutrophil heterogeneity by improving isolation methods, single-cell RNA extraction, sequencing and bioinformatic pipelines. Advanced flow cytometry 3D analysis, and machine learning validated our gating system model, by including positive neutrophil markers and excluding other immune cells and uncovered neutrophil heterogeneity. Considering specific cell markers, unique mitochondrial content, stringent and less stringent filtering strategies, our transcriptome single cell findings unraveled novel neutrophil subpopulations. Collectively, this methodology accelerates the discovery of salivary immune landscapes, with the promise of improving the understanding of diversification mechanisms, clinical diagnostics in health and disease, and guide targeted therapies.

Published: July 2020

Abstract
Objectives: There is a paucity of research on patterns of cyber-victimization in minority groups, including immigrants. This study aimed at identifying individual, interpersonal and contextual characteristics associated with cyber-victimization among immigrants and non-immigrants.Methods: We drew on nationally representative data from adolescents and adults in the Canadian General Social Survey on victimization (2014). Multivariable logistic regression was employed to identify potential factors associated with cyber-victimization in the last 12 months, stratified by immigrant status and sex. Results: Among 27,425 survey respondents, the weighted prevalence of cyber-victimization in the last 12 months was 2.1% among immigrants and 2.3% among non-immigrants. Cyber-victimization rates differed significantly by sex among immigrants (2.8% for males vs. 1.4% for females), but not among non-immigrants (2.1% for males vs. 2.4% for females). While most other factors associated with cyber-victimization were similar for immigrants and non-immigrants, we found pronounced associations of past child maltreatment (adjusted prevalence odds ratio [aPOR] 4.85, 95% confidence interval [CI] 2.76, 8.52) and residence in an unwelcoming neighbourhood (aPOR 5.08, 95% CI 2.44, 10.55) with cyber-victimization among immigrants that were diminished or absent among non-immigrants. Additionally, sex-stratified analyses among immigrants showed cyber-victimization to be strongly associated with having a mental health condition (aPOR 3.50, 95% CI 1.36, 8.97) among immigrant males only, and with perceived discrimination (aPOR 4.08, 95% CI 1.65, 10.08), as well as being under 24 years old (aPOR 3.24, 95% CI 1.09, 9.60) among immigrant females.Conclusions: Immigration status and sex were differentially associated with cyber-victimization. Findings support the salience of a social-ecological perspective and gender-stratified analyses to better elucidate complex pathways linking cyber-victimization to potential gender-based health inequities among immigrants.

Published: July 2020

Abstract
Background: Crosstalk between cancer cells and tumor-associated macrophages (TAMs) mediates tumor progression in colorectal cancer (CRC). Cytoplasmic polyadenylation element binding protein 3 (CPEB3) has been shown to exhibit tumor-suppressive role in CRC.Methods: The expression of CPEB3, CD68, CD86 and CD163 was determined in CRC tissues. SW480 or HCT116 cells overexpressing CPEB3 and LoVo or RKO cells with CPEB3 knockdown were constructed. Stably transfected CRC cells were co-cultured with THP-1 macrophages to determine the malignant phenotype of CRC cells, macrophage polarization, and secretory signals. The inhibition of CPEB3 on tumor progression and M2-like TAM polarization was confirmed in nude mice.Results: Decreased CPEB3 expression in CRC was associated with fewer CD86+ TAMs and more CD163+ TAMs. CPEB3 knockdown in CRC cells increased the number of CD163+ TAMs and the expression of IL1RA, IL-6, IL-4 and IL-10 in TAM supernatants. TAMs enhanced CRC cell proliferation and invasion via IL-6, and then activated the IL-6R/STAT3 pathway in CRC cells. However, CPEB3 reduced the IL-6R protein levels by directly binding to IL-6R mRNA, leading to decreased phosphorylated-STAT3 expression in CRC cells. CCL2 was significantly increased in CPEB3 knockdown cells, while CCL2 antibody treatment rescued the effect of CPEB3 knockdown in promoting CD163+ TAM polarization. Eventually, we confirmed that CPEB3 inhibits tumor progression and M2-like TAM polarization in vivo. Conclusions: CPEB3 is involved in the crosstalk between CRC cells and TAMs by targeting IL-6R/STAT3 signaling.
Bidirect effects from cisplatin combine with rosmarinic acid (RA) or hot water extracts of Glechoma hederacea (HWG) on renal cancer cells
Authors: Chou Su-Tze , Ho Bing Ying , Tai Yu Ting , Huang Chun Jen , Chao Wen Wan 
Published: July 2020

Abstract
Background: Cisplatin (CDDP) is a chemotherapeutic drug which also causes adverse side effects. Glechoma hederacea is a traditional Chinese herb belonging to the Labiatae family and has many biological activities. Our previous study indicated that rosmarinic acid (RA) was the most abundant phytochemical in G. hederacea. However, the antioxidant or anti-inflammatory effects of the combined treatment of G. hederacea, RA and CDDP on human renal cell carcinoma (RCC) 786-O cells have not been clearly demonstrated. We aimed to investigate the bioefficacy of hot water extracts of G. hederacea (HWG) and RA in inhibiting RCC 786-O cell activity and its synergism with CDDP against metastatic renal cancer cell. Methods: Bioactivities of the combination treatment of HWG, RA, HWG/CDDP and RA/CDDP were assessed using the MTT assay and transwell migration, and the crude extract/compound efficacy was evaluated using wound healing migration assays, flow cytometry and western blotting. Results: Our study indicates that CDDP inhibits 786-O cell proliferation and migration and HWG and RA protect against these effects. On the other hand, HWG and RA demonstrate a low cytotoxic effect in human renal proximal tubular epithelial cell line -2 (HK-2 cells). Cell cycle analysis found that HWG/CDDP and RA/CDDP combined treatment exerted cytotoxicity by inducing G2/M arrest and apoptosis. RA in combined with CDDP significantly inhibiting the expression of p-FAK (Tyr 925) in RCC 786-O cells in vitro.Conclusion: We propose that the inhibition of RA on RCC 786-O cell invasion and migration may partly occur through the downregulation of FAK phosphorylation. The HWG/CDDP and RA/CDDP combined treatments may be effective strategies for intervention of RCC 786-O cell activity.
