Abstract
Background: The financial burden of oral diseases is a growing concern as the medical expenses rise worldwide. The aim of this study was to investigate the dental expenditure, analyze its progressivity and horizontal inequality under the general health finance and insurance system, and identify the key social determinants of the inequality for Chinese adults. Methods: A secondary analysis used the data of 13,464 adults from the 4 th National Oral Health Epidemiological Survey (NOHES) in China was undertaken. The dental expenditure was collected and divided into out-of-pocket and health insurance payments. Horizontal inequality index and Kakwani index were used to analyze the horizontal inequality and progressivity, respectively. The decomposition model of the concentration index was set up to explore the associated socioeconomic determinants. Results: The results showed that a mean dental expenditure per capita of Chinese adults was $20.55 (95% Confidence Interval-CI: 18.83,22.26). Among those who actually used dental service, the cost was $100.95 (95%CI: 93.22,108.68). Over 90% of dental spending was due to out-of-pocket expenses. For self-reported oral health, the horizontal inequality index was -0.1391 and for the decayed tooth (DT), it was -0.2252. For out-of-pocket payment, the Kakwani index was -0.3154 and for health insurance payment it was -0.1598. Income, residential location, educational attainment, oral hygiene practice, self-reported oral health, age difference were the main contributors to the inequality of dental expenditure. Conclusion: Dental expenditure for Chinese adults was at a lower level due to underutilization. The ratio of payments of dental expenditure and utilization was disproportional, whether it was out-of-pocket or insurance payment. Individuals who were more in need of oral care showed less demand for service or not required service in time. For future policy making on oral health, it is worth the effort to further promote the awareness of the importance of oral health and utilization of dental service.

Abstract
Background: Babesia motasi is known as an etiological agent of human and ovine babesiosis. Diagnosis of babesiosis is traditionally performed by microscopy, examining Giemsa-stained thin peripheral blood smears. Rapid detection and accurate identification of species are desirable for clinical care and epidemiological studies. Methods: An easy to operate molecular method, which requires less capital equipment and incorporates cross priming amplification combined with a vertical flow (CPA-VF) visualization strip for rapid detection and identification of B. motasi. Results: The CPA-VF targets the 18S rRNA gene and has a detection limit of 50 fg per reaction; no cross reaction was observed with other piroplasms infective to sheep or Babesia infective to humans. CPA-VF and real-time (RT)-PCR had sensitivities of 95.2% (95% confidence interval [CI], 78.1-99.4%) and 90.5% (72-97.6%) and specificities of 95.8 (80.5-99.5%) and 97.9 (83.5-99.9%), respectively, versus microscopy and nested (n) PCR combined with gene sequencing. The clinical performance of the CPA-VF assay was evaluated with field blood samples from sheep (n = 340) in Jintai county, Gansu Province, and clinical specimens (n = 492) obtained from patients bitten by ticks. Conclusions: Our results indicate that the CPA-VF is a rapid, accurate, nearly instrument-free molecular diagnostic approach for identification of B. motasi. Therefore, it could be an alternative technique for epidemiological investigations and diagnoses of ovine and/or human babesiosis caused by B. motasi, especially in resource-limited regions.

Abstract
Background: In Pakistan there is a dire need to explore the quality of life in infertile males and females and its undesirable psychological outcomes. Thus, the aim of this study was: 1. To compare the QoL of males and females presenting at an infertility centre for treatment, 2. To assess the association of QoL with resilience, depression, and other socio-demographic factors in males and females presenting at an infertility clinic for treatment. Methods: An Analytical Cross-Sectional study was conducted and the study participants were recruited from the Australian Concept Infertility Medical Centre (ACIMC), Karachi, Pakistan. The non-probability (purposive) sampling strategy was used to recruit the participants. The sample size was 668. Data was analysed using STATA version 12. Results: After adjusting for the covariates we observed that the males who were less resilient their QoL was 8.47 units significantly lower and those who were depressed their QoL was 17.849 units significantly lower as compared to those who were more resilient and less depressed. Moreover, formal education, low monthly income, and friends were significantly associated with QoL among males . On the other hand, females who were less resilient their QoL was 8.606 units lower and those who were depressed their QoL was 19.387 units significantly lower as compared to those who were more resilient and less depressed. Additionally, formal education and low monthly income had a significant association with QoL among females. Conclusion: Fertility related QoL of men and women has a significant association with no formal education, number of friends, income, depression and resilience. Therefore, health care professionals in the field of infertility must be adequately trained to respond to the needs of individuals going through these psychological problems.

Abstract
Background: Sarcopenia is a progressive condition that is characterized by decreases in skeletal muscle mass and function. Although previous studies reported that sarcopenia is associated with non-alcoholic steatohepatitis (NASH), the underlying mechanisms remain unclear. We herein focused on glyceraldehyde, an intermediate of glucose/fructose metabolism. We previously designated glyceraldehyde-derived advanced glycation end-products (AGEs) as toxic AGEs (TAGE) because of their cytotoxicity and involvement in lifestyle-related diseases, such as NASH. We hypothesized that TAGE is associated with sarcopenia. Methods: C2C12 cells, which are murine myoblasts, were treated with 0, 0.5, 1, 1.5, and 2 mM glyceraldehyde for 24 h. Cell viability and intracellular TAGE were then assessed using 5-[2,4,-Bis(sodioxysulfonyl)phenyl]-3-(2-methoxy-4-nitrophenyl)-2-(4-nitrophenyl)-2H-tetrazole-3-ium (WST-8) and slot blot assays. Cells were pretreated with 8 mM aminoguanidine , an inhibitor of AGE production, for 2 h followed by 0, 1.5, and 2 mM glyceraldehyde for 24 h. Cell viability and intracellular TAGE were then assessed. Serum TAGE levels in STAM mice, in which there were four stages (no steatosis, simple steatosis, steatohepatitis, and fibrosis), were measured using an enzyme-linked immunosorbent assay. Results were expressed as TAGE units (U) per milliliter of serum, with 1 U corresponding to 1.0 μg of glyceraldehyde-derived AGE-bovine serum albumin (BSA) (TAGE-BSA). The viability of cells treated with 20, 50, and 100 μg/mL non-glycated BSA and TAGE-BSA for 24 h was assessed using the WST-8 assay. Results: In C2C12 cells treated with 1.5 and 2 mM glyceraldehyde, cell viability decreased to 47.7% ( p =0.0021) and 5.0% ( p =0.0001) and intracellular TAGE levels increased to 6.0 and 15.9 μg/mg protein, respectively. Changes in cell viability and TAGE production were completely inhibited by 8 mM aminoguanidine. Serum TAGE levels at the steatohepatitis and fibrosis stages were 10.51 ±1.16 and 10.44±0.95 U/mL, respectively, and were higher than that at the no steatosis stage (7.27±0.18 U/mL). Cell death was not induced by 20 or 50 μg/mL TAGE-BSA. The viabilities of C2C12 cells treated with 100 μg/mL non-glycated BSA and TAGE-BSA were 105.0% ( p =0.2890) and 85.3% ( p =0.0217), respectively. Conclusion: Intracellular TAGE strongly induce myoblast cell death and may cause sarcopenia. Therefore, TAGE may play a crucial role in sarcopenia associated with NASH .

Abstract
Background: Genetic diversity in Plasmodium falciparum poses a major threat to malaria control and elimination interventions. Characterization of the genetic diversity of Plasmodium falciparum strains can be used to assess intensity of parasite transmission and identify potential deficiencies in malaria control programmes, which provides vital information to evaluating malaria elimination efforts. In this study, we investigated the P. falciparum genetic diversity and genotype multiplicity of infection in parasite isolates from cases with uncomplicated P. falciparum malaria in Southwest Ethiopia.Methods: A total of 80 P. falciparum microscopy and qPCR positive blood samples were collected from study participants aged six months to sixty years, who visited the health facilities during study evaluating the efficacy of arthemeter-lumefantrine from September-December, 2017. Polymorphic regions of the msp-1 and msp-2 were genotyped by nested polymerase chain reactions (nPCR) followed by gel electrophoresis for fragment analysis.Results: Of 80 qPCR-positive samples analyzed for polymorphisms on msp-1 and msp-2 genes, the efficiency of msp-1 and msp-2 gene amplification reactions with family-specific primers were 95 % and 98.8%, respectively. Allelic variation of 90% (72/80) for msp-1 and 86.2% (69/80) for msp-2 were observed. K1 was the predominant msp-1 allelic family detected in 20.8% (15/72) of the samples followed by MAD20 and RO33. Within msp-2, allelic family FC27 showed a higher frequency (26.1%) compared to IC/3D7 (15.9%). Ten different alleles were observed in msp-1 with 6 alleles for K1, 3 alleles for MAD20 and 1 allele for RO33. In msp-2, 19 individual alleles were detected with 10 alleles for FC27 and 9 alleles for 3D7. Eighty percent (80%) of isolates had multiple genotypes and the overall mean multiplicity of infection was 3.2 (95% CI: 2.87- 3.46). The heterozygosity indices were 0.43 and 0.85 for msp-1 and msp-2, respectively. There was no significant association between multiplicity of infection and age or parasite density.Conclusions: The study revealed high levels of genetic diversity and mixed-strain infections of P. falciparum populations in Chewaka district, Ethiopia, suggesting that both, endemicity level and malaria transmission remain high and that strengthened control efforts are needed in Ethiopia.

Abstract
Background: This study focused on different exercise motivations, especially mood regulation and their relation to the sociodemographic status, exercise pattern and physical conditions of adults and older adults in China who did not undergo interventions.Methods: A total of 5242 participants aged 20-69 years from 2016 to 2018 were recruited in this cross-sectional study to finish the questionnaire of Guangdong National Physique Monitoring organized by the Guangzhou Institute of Sports Science. Multiple statistical analyses methods were used to study each exercise motivation and its sociodemographic characteristics (gender, age, education and job), exercise measurements (frequency, duration and intensity) and physical conditions (BMI, abdominal obesity and basic diseases). An exercise index that is good for mental health (index 1: 45 min per session and 3-5 times per week; index 2: exercise motivation of mood regulation and exercise 60-120 min per week) was also used to investigate the number and type of people who were more likely to meet the index. Results: In our study, 44.9% (2355/5242) of participants showed exercise inactivity. No gender difference was observed among those who exercised for mood regulation. Only older participants and those with an average level of education showed a significant association with mood regulation. Few people met the index that is good for mental health (16.64% (872/5242) met index 1 and 2.84% (149/5242) met index 2), and higher education showed a significant association with a reduction in the mental health burden and the prevention of depression. Conclusion: This investigation suggests motivating people to be more active, educating people on the mental health benefits of exercise.

Abstract
Background Community engagement approaches that have impacted on health outcomes are often time intensive, small-scale and require high levels of financial and human resources. They can be difficult to sustain and scale-up in low resource settings. Given the reach of health services into communities in low income countries, the health system provides a valuable and potentially sustainable entry point that would allow for scale-up of community engagement interventions. This study explores the process of developing an embedded approach to community engagement taking the global challenge of antibiotic resistance as an example.Methods The intervention was developed using a sequential mixed methods study design. This consisted of: exploring the evidence base through an umbrella review, and identifying key international standards on the appropriate use of antibiotics; undertaking detailed formative research through a) a qualitative study to explore the most appropriate mechanisms through which to embed the intervention within the existing health system and community infrastructure, and to understand patterns of knowledge, attitudes and practice regarding antibiotics and antibiotic resistance; and b) a household survey – which drew on the qualitative findings - to quantify knowledge, and reported attitudes and practice regarding antibiotics and antibiotic resistance within the target population; and c) drawing on appropriate theories regarding change mechanisms and experience of implementing community engagement interventions to co-produce the intervention processes and materials with key stakeholders at policy, health system and community level.Results A community engagement intervention was co-produced and was explicitly designed to link into existing health system and community structures and be appropriate for the cultural context, and therefore have the potential to be implemented at scale. We anticipate that taking this approach increases local ownership, as well as the likelihood that the intervention will be sustainable and scalable.Conclusions This study demonstrates the value of ensuring that a range of stakeholders co-produce the intervention, and ensuring that the intervention is designed to be appropriate for the health system, community and cultural context.

Abstract
Background Basal-like breast cancer (BLBC) is a poorly characterised, heterogeneous disease. Patients are diagnosed with aggressive, high-grade tumours and often relapse with chemotherapy resistance. Detailed understanding of the molecular underpinnings of this disease is essential to the development of personalised therapeutic strategies. Inhibitor of Differentiation 4 (ID4) is a helix-loop-helix transcriptional regulator required for mammary gland development. ID4 is overexpressed in a subset of BLBC patients, associating with a stem-like poor prognosis phenotype, and is necessary for the growth of cell line models of BLBC, through unknown mechanisms. Methods Here, we have defined unique molecular insights into the function of ID4 in BLBC and the related disease high-grade serous ovarian cancer (HGSOC), by combining RIME proteomic analysis, ChIP-seq mapping of genomic binding sites and RNA-seq. Results These studies reveal novel interactions with DNA damage response proteins, in particular, mediator of DNA damage checkpoint protein 1 (MDC1). Through MDC1, ID4 interacts with other DNA repair proteins (γH2AX and BRCA1) at fragile chromatin sites. ID4 does not affect transcription at these sites, instead binding to chromatin following DNA damage. Analysis of clinical samples demonstrates that ID4 is amplified and overexpressed at a higher frequency in BRCA1 -mutant BLBC compared with sporadic BLBC, providing genetic evidence for an interaction between ID4 and DNA damage repair deficiency. Conclusions These data link the interactions of ID4 with MDC1 to DNA damage repair in the aetiology of BLBC and HGSOC.

Abstract
Background: The prevalence of malaria in pregnancy and its complications, remain very high in Nigeria. This study aimed to determine the effects of a malaria health educational intervention based on the information-motivation-behavioural skills (IMB) model on malaria preventive practices and pregnancy outcomes. Methods: The study was a randomized controlled parallel-group study, where 372 randomly selected antenatal care attendees were randomly assigned to one of either two groups after collecting baseline data. The intervention group then received a four-hour health education intervention developed based on the IMB model, while the control group received a similarly designed health education on breastfeeding, and were then followed-up to the end of their pregnancies. The intention-to-treat analysis using the generalized linear mixed models was used to analyse the data obtained. Results: The reported frequency of ITN use and dose of IPTp taken, were higher in the intervention group by 0.32 levels (p=0.024) and 0.37 doses (p<0.001) respectively, implying that for 32% and 37% of the participants, an individual in the intervention group slept more frequently under an ITN by one day, and had also took one dose of IPTp more than an individual in the control group. The intervention group also achieved a haematocrit level of 0.80% higher than the control group. The intervention however, had no significant effect on the incidence of malaria diagnosis or babies’ birth weights. Conclusion: The intervention was effective in improving ITN use, IPTp uptake, and haematocrit levels. It is therefore recommended for the module to be adopted and incorporated into the routine antenatal care programmes in the state.

Abstract
Teacher self-efficacy, as a socio-affective concept, has been abundantly studied in relation to different factors. However, it seems that the consequences of teachers' self-efficacy have not been appropriately explored to the present date. The present study aimed at investigating the consequences of EFL teachers' teaching self-efficacy. In so doing, a qualitative research method was used. The data were collected through semi-structured interviews with 20 EFL teachers who were selected through purposive sampling. The interviews were content analyzed thematically. Findings showed that self-efficacy has three main consequences: pedagogical, learner-related, and psychological. Each of these consequences has several sub-categories. It can be concluded that high self-efficacy affects teachers’ teaching practices, learners’ motivation, and achievement. It also affects teachers’ burn-out status, psychological being, as well as their job satisfaction. The findings can be theoretically and pedagogically important to EFL teachers, teacher-trainers, and administrators of educational settings.
