Abstract
Background
Skilled Birth Attendance (SBA) is important in achieving the Sustainable Development Goals (SDGs) targets 3.1, 3.2 and 3.3.1. Ghana has made steady progress in SBA, yet, unsupervised deliveries still occur. The introduction of the Free Maternal Health Care Policy under the National Health Insurance Scheme (FMHCP under the NHIS) has improved the uptake of SBA but with some implementation challenges. This narrative review sought to explore the factors influencing the FMHCP under the NHIS provision for skilled delivery services in Ghana.

Methods
Electronic searches were conducted of databases including PubMed, Popline, Science direct, BioMed Central, Scopus and Google scholar for peer reviewed articles as well as grey articles from other relevant sources, published between 2003 and 2021 on factors influencing FMHCP/NHIS provision for skilled delivery services in Ghana. Keywords used in the literature search were in various combinations for the different databases. The articles were screened to determine the inclusion and exclusion criteria and quality was assessed using a published critical appraisal checklist. A total of 516 articles were retrieved for initial screening based on their titles, of which 61 of them, were further screened by reading their abstracts and full text. Of this number, 22 peer-reviewed and 4 grey articles were selected for the final review based on their relevance.

Results
The study revealed that the FMHCP under the NHIS does not cover the full costs associated with skilled delivery and low socioeconomic status of households affects SBA. Also, funding and sustainability, hinders the quality-of-service delivery offered by the policy.

Conclusion
For Ghana to achieve the SDGs above and further improve SBA, the cost associated with skilled delivery should be fully covered by the NHIS. Also, the government and the key stakeholders involved in the policy implementation, must put in place measures that will enhance the operation and the financial sustainability of the policy.

AbstractBackgroundAdolescent depression is a serious mental disorder that makes family problems, learning challenges, drug addiction, and increases absenteeism from school. It also has a major impact on a person’s ability to manage his or her daily tasks. In the end, the condition may result in self-destruction. Research is scarce among high schools in the study setting. Therefore, this study aimed to assess the prevalence and its associated factors of depression among high school adolescent students in Bahirdar City, Northwest Ethiopia in 2022.MethodsAn institutional-based cross-sectional study was done from June 18 to July 16, 2022, among public and private high school adolescent students in Bahir Dar City, Amhara region, Ethiopia. A two-stage sampling technique was utilized. First, stratification by school type was made and schools were selected 30–40% by using a simple random sampling technique. Finally, an updated sampling frame was taken from each school director to select a sample of 584 study participants after proportional allocation by simple random sampling from six high schools. Patient Health Questionnaires were used to assess depression in high school students. The independent variables, like substance-related factors, were assessed by yes-or-no questions, and the academic stressor by academic stress in secondary education, was assessed by structured questionnaires. Binary and multivariate logistic regressions were used to identify factors associated with depression. Statistical significance was declared at a 95% confidence interval when the value of p was less than or equal to 0.05.ResultsThe response rate of the participants was 96.9%. The overall magnitude of adolescent depression was found to be 22.1% (95%CI 18.7, 25.7%). Being female (AOR: 3.43; 95%CI 2.11, 5.56), small family size (AOR: 3.01; 95%CI 1.47, 6.15); ever alcohol use (AOR: 2.40; 95%CI 1.51, 3.81); attending a public school (AOR: 3.01; 95%CI 1.68, 5.40), and having a history of abuse (AOR: 1.92; 95%CI 2.2, 3.08) were associated with depression.ConclusionIn this study, the magnitude of depression among high school students in Bahir Dar City was higher than the national threshold. There was a significant association between sex, family size of parents, ever alcohol use, public schools, and having a history of abuse with depression among adolescents. Hence, it is better for schools to screen and provide intervention for depression in public high school students and offer therapies, especially in females and those with a history of abuse, small family size, or alcohol use.

Abstract
Background
There is a lack of methodologically strong measure to assess perceived social support among Arabic-speaking populations. Our main objective was therefore to examine the psychometric properties of an Arabic translation of the Multidimensional Social Support Scale (MSPSS) in a sample of Arabic-speaking Lebanese adults from the general population.

Methods
We adopted a cross-sectional design involving a convenience sample of 387 non-clinical Lebanese adults aged 26.17 ± 11.47 years (58.4% females). Participants were administered a web-based anonymous questionnaire containing the MSPSS, the 10-item Connor-Davidson Resilience Scale, and the Post traumatic growth Inventory-Short Form. The forward-backward translation method was applied. Confirmatory factor analysis (CFA) and gender invariance in the MSPSS were examined. McDonald’s ω coefficients were calculated as internal consistency indicators.

Results
The Arabic MSPSS and its subscales have a high internal consistency with McDonald’s ω values between 0.94 and 0.97. CFA indicated that fit of the three-factor model was acceptable. All indices suggested that configural, metric, and scalar invariance was supported across gender. Both genders exhibited no significant difference in all MSPSS dimensions. Convergent validity was supported by showing that all three MSPSS sub-scores and total score correlated significantly and positively with resilience and posttraumatic growth scores.

Conclusion
Although further cross-cultural validations involving other Arab countries and communities are still needed, we preliminarily suggest that this scale is applicable to the broad Arabic-speaking people for the measurement of perceived social support in clinical and research contexts.

Abstract
Background
This study aims to investigate the effect of a course of selected corrective exercises on posture, scapula-humeral rhythm and performance of adolescent volleyball players.

Methods
30 adolescent volleyball players with upper cross syndrome were purposefully selected and assigned into 2 control and training groups. The degree of back curvature was evaluated using a flexible ruler, forward head and forward shoulder size by photographic method, scapula-humeral rhythm by Lateral Scapular Slide Test (LSST), and performance by closed kinetic chain test. The training group performed the exercises for 10 weeks. After the exercises, the post-test was administered. To analyze the data, analysis of co-variance tests and paired t-test at the level of 0.05 were employed.

Results
The research results showed that corrective exercises have a significant effect on abnormalities of forward head, forward shoulder, kyphosis, scapula-humeral rhythm and performance.

Conclusions
Corrective exercises can be effective in reducing shoulder girdle and spine abnormalities and improving scapula- humeral rhythm and performance of volleyball players.

Published: June 2023

Abstract
Background
In this study, we investigated the effects of differences in scanning pathways during optical impression on the trueness and precision of full-arch impressions.

Methods
Reference data were obtained using a laboratory scanner. All optical impressions were measured across the dental arch using TRIOS® 3 in four different pathways. The reference and optical impression data were superimposed using the best-fit method. The criteria for superimposition were based on the starting side of the dental arch (partial arch best-fit method, PB) and based on the full arch (full arch best-fit method, FB). The data were compared between the left and right molars (starting and ending sides). The scan deviations for trueness (n = 5) and precision (n = 10) were obtained for each group by calculating the root mean square (RMS) of the deviation at each measurement point. Visual observations using superimposed color map images revealed variations in trueness.

Results
There were no significant differences in scanning time or amount of scan data between the four scanning pathways. Trueness did not differ significantly among the four pathways with respect to the starting and ending sides, regardless of the superimposition criteria. Precision with PB was significantly different between scanning pathways A and B, and pathways B and C for the starting sides, and between scanning pathways A and B, and pathways A and D for the ending sides. In contrast, there was no significant difference between the starting and ending side in pathways for FB. Regarding PB, color map images showed a large error range in the direction toward the molar radius for the occlusal surface and cervical regions on the ending sides.

Conclusion
Differences in the scanning pathways did not affect trueness, regardless of the superimposition criteria. On the other hand, differences in the scanning pathways affected the precision of the starting and ending sides with PB. Scanning pathways B and D were more precise on the starting and ending sides, respectively.

Published: June 2023

Abstract
Background
A well-coordinated supply chain ensures the sustainable availability of life-saving medicines that improve public health outcomes. Information Communication Technology (ICT) is one of the strategies for optimizing supply chain coordination. However, there is a paucity of data on how it affects supply chain practice and performance at the Ethiopian Pharmaceutical Supply Agency (EPSA).

Objective
This study aimed to explore the relationships between information and communication technology, supply chain practice, and pharmaceutical supply chain operational performance using a structural equation modeling approach.

Methods
We conducted an analytical cross-sectional study between April and June 2021. Three hundred twenty EPSA employees participated in the survey. We used a pretested, self-administered five-point Likert scale questionnaire to collect the intended data. A structural equation modeling confirmed the relationship between the constructs (information communication technology, supply chain practices, and performance). Thus, the measurement models were first validated using exploratory and confirmatory factor analysis in SPSS/AMOS software. A p-value of less than 5% indicated statistical significance.

Results
Of the 320 questionnaires distributed, 300 participants (202 males and 98 females) duly responded. In this survey, supply chain practices (mainly customer relationship management and information sharing) and ICT had significant positive direct effects on operational performance with standardized regression weights (β) of 0.65 (p < .001) and 0.29 (p < .001), respectively. On the other hand, 73% of the variations in operational performance were explained by ICT and supply chain practices, wherein ICT played moderate mediation effects between supply chain practice and performance (VAF = 0.24, p < .001). Despite the significant positive influence of ICT, the agency still faced data visibility problems with customers and other supply chain partners.

Conclusion
The findings revealed that supply chain practices and ICT implementation impacted the agency’s supply chain performance positively and significantly. The ICT implementation practice in the agency posited a significant positive partial mediating role between supply chain practice and operational performance. Thus, if the agency focuses on the automation and integration of customer relationship management and the practice of information exchange, the essential supply chain practices, it can further improve operational performance.

Published: June 2023

AbstractBackgroundThalassemia has brought serious health threats and economic burdens to patients worldwide. There is no sovereign remedy for thalassemia, both conventional and Traditional Medicine (TM) methods have certain effects on this disease. As typical of TM, Traditional Chinese Medicine (TCM) has been widely used in the treatment of thalassemia. Previous studies mainly focused on conventional treatments for thalassemia and patients’ medical burden, but no research has examined the effects of TCM use on the economic burdens for thalassemia inpatients in mainland China. The main objective of this study is to compare the medical cost differences between TCM users and TCM nonusers, furtherly, we will discuss the role of TCM use in the treatment of thalassemia.MethodsWe employed the 2010–2016 Medicare claims database provided by the China Health Insurance Research Association (CHIRA). Chi-square and Mann-Whitney tests were used to analyze the differences between TCM users and TCM nonusers. Multiple regression analysis was performed using the ordinary least squares method to compare the TCM users’ inpatient medical cost with TCM nonusers’, and to further examine the correlation between TCM cost, conventional medication cost and nonpharmacy cost for TCM users.ResultsA total of 588 urban thalassemia inpatients were identified, including 222 TCM users and 366 TCM nonusers. The inpatient medical cost of TCM users was RMB10,048 (USD1,513), which was significantly higher than TCM nonusers (RMB1,816 (USD273)). Total inpatient cost for TCM users was 67.4% higher than those of TCM nonusers (P < 0.001). With confounding factors fixed, we found that the conventional medication cost and nonpharmacy cost were positively correlated with TCM cost.ConclusionTotal hospitalization expenses for TCM users were higher than TCM nonusers. Both the conventional medication cost and nonpharmacy cost of TCM users were all higher than TCM nonusers. We infer TCM plays a complementary role, rather than an alternative, in the treatment of thalassemia due to the lack of cooperative treatment guidelines. It is recommended that a cooperative diagnosis and treatment guidelines should be generated to balance the use of TCM and conventional medicine for treating thalassemia, so as to reduce the economic burdens on patients.
Engineering of cyclodextrin glycosyltransferase improves the conversion efficiency of rebaudioside A to glucosylated steviol glycosides and increases the content of short-chain glycosylated steviol glycoside

Published: June 2023

Abstract
Background
Compared with steviol glycosides, the taste of glucosylated steviol glycosides is better and more similar to that of sucrose. At present, cyclodextrin glucanotransferase (CGTase) is primarily used to catalyze the conversion of steviol glycosides to glucosylated steviol glycosides, with soluble starch serving as a glycosyl donor. The main disadvantages of enzymatic transglycosylation are the limited number of enzymes available, the low conversion rates that result in low yields, and the lack of selectivity in the degree of glycosylation of the products. In order to fill these gaps, the proteome of Alkalihalobacillus oshimensis (also named Bacillus oshimensis) was used for mining novel CGTases.

Results
Here, CGTase-15, a novel β-CGTase with a wide pH adaptation range, was identified and characterized. The catalyzed product of CGTase-15 tasted better than that of the commercial enzyme (Toruzyme® 3.0 L). In addition, two amino acid sites, Y199 and G265, which play important roles in the conversion of steviol glycosides to glucosylated steviol glycosides were identified by site-directed mutagenesis. Compared with CGTase-15, CGTase-15-Y199F mutant significantly increased the conversion rate of rebaudioside A (RA) to glucosylated steviol glycosides. Compared with CGTase-15, the content of short-chain glycosylated steviol glycosides catalyzed by CGTase-15-G265A mutant was significantly increased. Moreover, the function of Y199 and G265 was verified in other CGTases. The above mutation pattern has also been applied to CGTase-13 (a CGTase discovered by our laboratory with great potential in the production of glycosylated steviol glycosides), confirming that the catalytic product of CGTase-13-Y189F/G255A mutant has a better taste than that of CGTase-13.

Conclusions
This is the first report on the improvement of the sensory profiles of glycosylated steviol glycosides through site-directed mutagenesis of CGTase, which is significant for the production of glycosylated steviol glycosides.

Abstract
Background
Age-related macular degeneration (AMD), characterized by the degeneration of retinal pigment epithelium (RPE) and photoreceptors, is the leading cause of irreversible vision impairment among the elderly. RPE senescence is an important contributor to AMD and has become a potential target for AMD therapy. HTRA1 is one of the most significant susceptibility genes in AMD, however, the correlation between HTRA1 and RPE senescence hasn’t been investigated in the pathogenesis of AMD.

Methods
Western blotting and immunohistochemistry were used to detect HTRA1 expression in WT and transgenic mice overexpressing human HTRA1 (hHTRA1-Tg mice). RT-qPCR was used to detect the SASP in hHTRA1-Tg mice and ARPE-19 cells infected with HTRA1. TEM, SA-β-gal was used to detect the mitochondria and senescence in RPE. Retinal degeneration of mice was investigated by fundus photography, FFA, SD-OCT and ERG. The RNA-Seq dataset of ARPE-19 cells treated with adv-HTRA1 versus adv-NC were analyzed. Mitochondrial respiration and glycolytic capacity in ARPE-19 cells were measured using OCR and ECAR. Hypoxia of ARPE-19 cells was detected using EF5 Hypoxia Detection Kit. KC7F2 was used to reduce the HIF1α expression both in vitro and in vivo.

Results
In our study, we found that RPE senescence was facilitated in hHTRA1-Tg mice. And hHTRA1-Tg mice became more susceptible to NaIO3 in the development of oxidative stress-induced retinal degeneration. Similarly, overexpression of HTRA1 in ARPE-19 cells accelerated cellular senescence. Our RNA-seq revealed an overlap between HTRA1-induced differentially expressed genes associated with aging and those involved in mitochondrial function and hypoxia response in ARPE-19 cells. HTRA1 overexpression in ARPE-19 cells impaired mitochondrial function and augmented glycolytic capacity. Importantly, upregulation of HTRA1 remarkably activated HIF-1 signaling, shown as promoting HIF1α expression which mainly located in the nucleus. HIF1α translation inhibitor KC7F2 significantly prevented HTRA1-induced cellular senescence in ARPE-19 cells, as well as improved the visual function in hHTRA1-Tg mice treated with NaIO3.

Conclusions
Our study showed elevated HTRA1 contributes to the pathogenesis of AMD by promoting cellular senescence in RPE through damaging mitochondrial function and activating HIF-1 signaling. It also pointed out that inhibition of HIF-1 signaling might serve as a potential therapeutic strategy for AMD.

Published: June 2023

Abstract
Background
Sjögren’s syndrome (SS) is an autoimmune disease characterized by inflammation of the exocrine gland. An imbalance of gut microbiota has been linked to SS. However, the molecular mechanism is unclear. We investigated the effects of Lactobacillus acidophilus (L. acidophilus) and propionate on the development and progression of SS in mouse model.

Methods
We compared the gut microbiomes of young and old mice. We administered L. acidophilus and propionate up to 24 weeks. The saliva flow rate and the histopathology of the salivary glands were investigated, and the effects of propionate on the STIM1-STING signaling pathway were evaluated in vitro.

Results
Lactobacillaceae and Lactobacillus were decreased in aged mice. SS symptoms were ameliorated by L. acidophilus. The abundance of propionate-producing bacterial was increased by L. acidophilus. Propionate ameliorated the development and progression of SS by inhibiting the STIM1-STING signaling pathway.

Conclusions
The findings suggest that Lactobacillus acidophilus and propionate have therapeutic potential for SS.
