Abstract
Background Schistosomiasis is endemic in the uMkhanyakude district of KwaZulu-Natal, South Africa. The South Africa Department of Health (DoH) has decided to implement a schistosomiasis preventive mass drug administration program in all affected parts of the country. Quality management is part of the strategic objectives of the treatment program. We conducted a risk assessment and developed guidelines for the quality management of a schistosomiasis preventive treatment program for children aged five years and below in the uMkhanyakude District of KwaZulu-Natal. Methods We conducted a scenario planning exercise by interviewing 10 child health experts from the uMKhanyakude Health District to establish potential risks associated with a planned schistosomiasis preventive control treatment program for children aged five years old and below. The risks were analyzed using a modified Failure Mode and Effect Analysis (FMEA). An FMEA table was produced to guide the quality management of the planned schistosomiasis preventive control treatment program for children aged five years and below in the uMkhanyakude Health District. Results We identified potential risks, failure modes and possible failure corrective/preventive measures in the following activities that would be part of the mass treatment of children aged five years and below infected with schistosomiasis in the uMkhanyakude District. These included enrolment of children into the treatment program; general health checks; weight and height measurements; administration of drugs; reporting of side effects and monitoring and evaluation. Conclusion We were able to use FMEA guide quality management and identify potential risks associated with the planned schistosomiasis preventive treatment program for children aged five years old and below in the uMkhanyakude District of KwaZulu-Natal. The FMEA for this program will be useful to the quality management of schistosomiasis preventive treatment programs for this age group in other similar settings.

Abstract
Background: Although several studies assessed the effect of bisphosphonate (BIS) administration on alveolar bone loss, this relationship has not been fully investigated using longitudinal analysis. The aim of the this article is to predict annual alveolar bone loss in a subpopulation of older adults patients who were taking oral bisphosphonate (BIS), adjusting for systemic diseases and associated risk factors. Methods: This is a retrospective cohort study. We identified all subjects who reported receiving oral bisphosphonate from 2008–2015 (N=30) using the electronic health records of each patient to identify suitable radiographs for analysis. For the longitudinal data analysis, 26 subjects were eligible for inclusion, having at least two exposures of the complete mouth set or repeated bitewing radiographs at at least a one-year interval; they were then matched on age and sex to another 26 patients who did not report receiving bisphosphonate at any point of their life. Results: Mild periodontitis was higher in the BIS group compared to the no BIS group; however, moderate periodontitis was higher in the no BIS group. For those who did not take oral BIS, change over time was not significant after the two-year period. However, the BIS group had experienced 0.088 mm more bone loss compared to the no BIS group (95% CI: 0.001, 0.176. P-value = 0.048), adjusting for all other variables included in the model. Conclusion: The group that reported receiving oral bisphosphonates showed no improvement in maintaining alveolar bone level, and the use of oral BIS may not be effective in reducing annual alveolar bone loss; however, emerging evidence is promising for the use of bisphosphonate as an adjunctive local delivery medication for the management of periodontal diseases.

Published: September 2019

Abstract
Background: Dispersal is essential for terrestrial organisms living in disjunct habitats and constitutes a significant challenge for the evolution of wingless taxa. Springtails (Collembola), the sister-group of all insects (with Diplura), are reported since the Lower Devonian and are thought to have originally been subterranean. The order Symphypleona is reported since the early Cretaceous with genera distributed on every continent. This distribution implies an ability to disperse over oceans, however symphypleonan Collembola have never been reported in marine water contrary to other springtail orders. Despite being highly widespread, modern springtails are rarely reported in any kind of biotic association. Interestingly, the fossil record has provided occasional occurrences of Symphypleona attached by the antennae onto the bodies of larger arthropods.
Results: Here, we document the case of a ~16 Ma old fossil association: a winged termite and ant displaying not some, but 25 springtails attached or in close proximity to the body. The collembola exhibit rare features for fossils, reflecting their courtship and phoretic behaviours. By observing the modes of attachment of springtails on different arthropods, the sex representation and ratios in springtail antennal anatomies in new and previously reported cases, we infer a likely mechanism for dispersal in Symphypleona. By revealing hidden evidence of modern springtail associations with other invertebrates such as ants and termites, new compelling assemblages of fossil springtails, and the drastic increase of eusocial insects’ abundance during the Cenozoic (ants/termites comprising more than a third of insects in Miocene amber), we stress that attachment on winged castes of ants and termites may have been a mechanism for the worldwide dispersal of this significant springtail lineage. Moreover, by comparing the general constraints applying to the other wingless soil-dwelling arthropods known to disperse through phoresy, we suggest biases in the collection and observation of phoretic Symphypleona related to their reflexive detachment and infer that this behaviour continues today.
Conclusions: The specific case of tree resin entrapment represents the (so far) only condition uncovering the phoretic dispersal mechanism of springtails - one of the oldest terrestrial arthropod lineages living today.

Abstract
Background Lupus nephritis (LN) is a common complication of systemic lupus erythematosus that presents a high risk of end-stage renal disease. In the present study, we used CIBERSORT and gene set enrichment analysis (GSEA) of gene expression profiles to identify immune cell infiltration characteristics and related core genes in LN.
Results Datasets from the Gene Expression Omnibus, GSE32591 and GSE113342, were downloaded for further analysis. The GSE32591 dataset, which included 32 LN glomerular biopsy tissues and 14 glomerular tissues from living donors, was analyzed by CIBERSORT. Different immune cell types in LN were analyzed by the Limma software. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis based on GSEA were performed by clusterProfiler software. Lists of core genes were derived from Spearman correlation between the most significant GO term and differentially expressed immune cell gene from CIBERSORT. GSE113342 was employed to validate the association between selected core genes and clinical manifestation. Five types of immune cells revealed important associations with LN, and monocytes emerged as having the most prominent differences. GO and KEGG analyses indicated that immune response pathways are significantly enriched in LN. The Spearman correlation indicated that 15 genes, including FCER1G, CLEC7A, MARCO, CLEC7A, PSMB9, and PSMB8 , were closely related to clinical features.
Conclusions This study is the first to identify immune cell infiltration with microarray data of glomeruli in LN by using CIBERSORT analysis and provides novel evidence and clues for further research of the molecular mechanisms of LN.

Abstract
MR images (MRI) accurate segmentation of brain lesions is important for improving cancer diagnosis, surgical planning, and prediction of outcome. However, manual and accurate segmentation of brain lesions from 3D MRIs is highly
expensive, time-consuming, and prone to user biases. We present an efficient yet conceptually simple brain segmentation network (referred as Brain SegNet), which is a 3D residual framework for automatic voxel-wise segmentation of brain lesion. Our model is able to directly predict dense voxel segmentation of brain tumor or ischemic stroke regions in 3D brain MRIs. The proposed 3D segmentation network can run at about 0.5s per MRIs - about 50 times faster than previous approaches [1,2]. Our model is evaluated on the BRATS 2015 benchmark for brain tumor segmentation, where it obtains state-of-the-art results, by surpassing recently published results reported in [1,2]. We further applied the proposed Brain SegNet for ischemic stroke lesion outcome prediction, with impressive results achieved on the Ischemic Stroke Lesion Segmentation (ISLES) 2017 database.

Published: September 2019

Abstract
Background Melanoma can be lethal if not detected early and treated. Early detection can be facilitated via skin self-examination (SSE) and as such, SSE is part of melanoma follow-up care for individuals with a prior history, who face a life-long risk of reoccurrence. The objective of the current study was to identify short- and long-term predictors of SSE among melanoma survivors to inform future prevention interventions in high-risk groups. Method This is an observational study with longitudinal assessments conducted with adult melanoma patients in active follow-up care. Primary Outcome Measures: Behavioral outcomes, comprehensive SSE (checking up to 5 body areas in the last 3 months) and optimal SSE (checking the entire body at least monthly in the last 3 months) and were assessed at 3, 12, and 24 months post a dermatological educational session on skin cancer prevention. T tests and chi square analyses were used to examine changes in outcomes from 3 to 12 and 24 months. Linear and logistic regression models were used to examine the association between predictors and the primary outcomes. Results Comprehensive SSE did not decrease significantly from 3 (M=2.7, SD=1.1) to 12 (M=2.6, SD=1.2) and 24 months (M=2.4, SD=1.2) post the education session, with the stronger predictor at all timepoints being intentions to perform SSE. Optimal SSE was higher at 3 months (59%) compared to 12 (46%) and 24 months (34%) post, with key predictors including self-efficacy and intentions to perform SSE and male sex at 3 months post; self-efficacy and reliance on medical advice at 12 months post; and (lower) education and self-efficacy at 24 months post. Conclusions The key findings of this study are that 1) survivors maintain SSE behaviour over time, but rates of SSE performed in agreement with medical recommendations are higher immediately post standard dermatological education (i.e. usual care) and decrease somewhat over a 24-month period; and 2) the strongest psycho-social predictors of SSE are intentions and self-efficacy to perform the behavior, which are highly modifiable, for example via motivational interviewing and goal setting health interventions.

Published: September 2019

Abstract
Background: Conotruncal heart defects ( CTDs ) are a group of congenital heart malformations that cause anomalies of cardiac outflow tracts. In the past few decades, many genes related to CTDs have been reported. Serum response factor (SRF) is a ubiquitous nuclear protein that acts as transcription factor, and SRF was found to be a critical factor in heart development and to be strongly expressed in the myocardium of the developing mouse and chicken hearts. The targeted inactivation of SRF during heart development leads to embryonic lethality and myocardial defects in mice. Results: To illustrate the relationship between SRF and human heart defects, we screened SRF mutations in 527 CTD patients. Two novel mutations (p.G274D and p.G294C) of SRF were identified. Western blotting and real-time PCR showed that there were no obvious differences between the protein expression and mRNA transcription of mutants and wild-type SRF. A dual luciferase reporter assay showed that both SRF mutants (G274D and G294C) impaired SRF transcriptional activity at the SRF promoter and atrial natriuretic factor ( ANF ) promoter ( p <0.05), additionally, the mutants displayed reduced synergism with GATA4. Conclusion: These results suggest that SRF-p.G274D and SRF-p.G294C may have potential pathogenic effects.

Abstract
Objectives Research knowledge gap exists in addressing sexual reproductive health services to street adolescents globally. The intensity of SRH problem is high in the settings like Ethiopia where there is limited access and integration of services in the way it responds to the needs of the street adolescents and this study aimed at exploring risky sexual behaviors; needs and barriers of SRH services utilization among street adolescents in Nekemte town. Community based Cross-sectional study design with mixed approaches was used on sample size of 219 street adolescents. Supplementary qualitative data of 24 in-depth interviews were collected from the street adolescents and SRH service providers. Time-location sampling or venue sampling technique (VDT) was used for quantitative study. Quantitative data was analyzed by SPSS version 24.0.Results About 93% of street adolescents reported difficulty of accessing contraceptives. Behavioral change and sustainable access of SRH services is lacking among street adolescents; but, Knowledge gap is more evident in early adolescents (10-13) period than the other classes. Generally, street adolescents are deprived in terms of access of sexual reproductive health services. Mobile and flexible access of contraceptive should be designed targeting street adolescents.

Abstract
Background Tibet is located in the high altitude area of southwest China, which health level is influenced by specific factors. However, there was little research on Tibetan health condition. And the two-week prevalence rate is an important indicator to health status of residents. The purpose of this study was to understand the two-week prevalence rate and its influencing factors in Tibet. Methods Two-week prevalence rate was calculated using data from a population of 10493 aged 15 and above obtained from the sixth Health Service Survey of Tibet in 2018. Multivariate logistic regression analysis was used to further screen factors for gender, age, marital status, employment status and so on. Results The two-week illness prevalence rate was 20.1% in Tibet. According to the Multivariate logistic regression analysis the two-week prevalence rate was associated with gender, age, residence, marital status, employment status, respectively. Digestive system diseases are given priority, hypertension is the most common disease. Besides, the severity of two-week illness has differences in different groups. Conclusion This study identified a number of factors that appear to have a significant relationship with the two-week illness prevalence. Moreover, the two-week prevalence rates of women and older people were significantly higher, which should be paid attention to in the utilization of health services.

Published: September 2019

Abstract
Background Post-partum hemorrhage (PPH) is the leading cause of obstetric morbidity and mortality around the world. Prophylactic administration of tranexamic acid (TXA) in patients at risk for PPH is aimed at reducing estimated blood loss (EBL). Method This was a prospective cohort study. Patients at high risk of PPH were given 1000mg of TXA intravenously at cord clamping after delivery of the baby, and compared with high PPH risk controls who did not receive TXA. Both cesarean section deliveries (CD) and vaginal deliveries (VD) were included. The primary outcome was postpartum hemorrhage, and the secondary outcome was calculated estimated blood loss (cEBL). Results Between January 2017 and May 2017, 101 patients at high risk for PPH were enrolled. Fifty one received TXA and 50 did not. There were 20 cases of PPH in the TXA group compared with 30 cases in the control group (OR 0.43, 95% CI, NNT=5). The average cEBL for VD and CD were significantly lower in the patients who received TXA compared with controls: 561ml ±336ml compared with 841ml ±462ml (p=0.0006) for VD and 658ml ±294mL compared with 1024ml ±276 for CD (p=0.0007). Conclusions Intravenous TXA may be used as prophylaxis for PPH in obstetric patients at high risk.

Published: September 2019

Abstract
Background: Limiting factors in photosynthesis includes stomatal limitations, mesophyll limitations, and biochemical limitations, and mesophyll limitations are the leading limiting factors in photosynthesis as shown by many studies. Mesophyll conductance (gm) exerts significant influences on the photosynthetic capacity of crops, playing a decisive role in mesophyll limitations. The limiting factors in photosynthesis for many crops under water deficit and rehydration conditions have been studied, but few studies of this kind on sugar beet can be found. Results: Our study aimed to analyze the dynamic changes of mesophyll limitations, stomatal limitations, and biochemical limitations by examining the influences of water deficit and rehydration on photosynthetic characteristics, electron transport, and leaf anatomical structure. According to the analysis on photosynthetic characteristics, severe deficit irrigation treatment significantly decreased photosynthesis rate, light saturation point, and CO2 saturation point. After rehydration, there was no difference in photosynthetic characteristics between the well irrigated sugar beets and the ones with severe deficit irrigation treatment. The analysis on leaf anatomical structure found that sugar beets dealt with water deficit by increasing leaf (mesophyll) thickness, and the severe deficit irrigation treatment significantly decreased the number of chloroplasts without influencing each one in terms of shape and cross-section area. No significant influence of water deficit was found on the electron transport rate (Jflu) of sugar beets during the process of CO2 assimilation. Conclusions: Therefore, deficit irrigation treatments cannot significantly influence photosynthetic assimilation of sugar beets. The analysis of limitations in photosynthesis showed that the stomatal and biochemical limitations increased while the mesophyll limitations decreased when sugar beets were under water deficit; however, the stomatal and biochemical limitations decreased while the mesophyll limitations increased after rehydration. The photosynthesis of sugar beets was mainly influenced by mesophyll limitations, and the limiting factors changed significantly only for severe deficit irrigation treatment.

Published: September 2019

Abstract
Background: BALB/c mice showed easily induced Th2-type responses in several infection models. Certain macrophage phenotypes contribute to liver fibrosis. We characterized changes in macrophages phenotype (M1/M2) during fibrogenesis in liver fibrosis mice model. Methods: Carbon-tetrachloride (CCl 4 ) hepatic-fibrosis was induced in BALB/c mice. Liver macrophages isolated were identified for M1 and M2 by CD80/iNOS and CD273 (programmed death ligand 2 (PDL2)/CD206, respectively. IL-4 were induced i.p along week-2 to week-4 of CCl 4 . Liver proteins were assessed for aSMA expressions, histology and ALT levels. Results: CCl 4 -induced hepatic-fibrosis showed increased CD273 (from 20.1%± 3.1in naïve mice to 27.8%±3.2 in fibrotic mice; P=0.01) while gradual decrease in CD80 (from 12%±6.2 in naïve mice to 1.97%±0.4 in fibrotic mice; P<0.02). The overall data showed decreased M1/M2 ratio. M2-macrophages showed inhibited expressions of IFN-g, IL-12 and vitamin-D-receptor (VDR) while high TGF-b levels. ALT, H&E staining intensities and aSMA showed gradually increased along fibrosis while metabolic markers of serum insulin, vitamin D and VDR decreased. IL-4 inductions while inhibited fibrosis it elevated metabolic markers. Conclusions: M2-macrophages express less IFN-g and IL-12, which might indicate inability differentiation of naive T cells into Th1 cells. IL-4 has an anti-fibrotic effects through antagonize M2-macrophages of TGF-b and ameliorating insulin, vitamin D, VDR and consequently attenuated liver-fibrosis.
