Abstract
Objective
To explore the effect of children’s migration on their oral health outcomes in multi-beneficial kindergartens in Jiangnan District, Nanning, China, and to provide a basis for improving the oral health of migrant children.

Methods
A cross-sectional study was conducted among 470 children aged 5 years in Jiangnan District, Nanning, Guangxi. A questionnaire was used to collect information on their demographic and socioeconomic background, migration experience, eating habits, oral hygiene behaviours and utilization of dental care services. Dental caries of primary teeth was examined using the decayed, missing, and filled teeth (dmft) index recommended by the World Health Organization. Dental caries experience and oral health-related behaviours were compared between migrant and resident children. The impact of children’s migration attributes on their oral health outcomes was examined by univariate and multivariate analyses.

Results
Among the examined children, 52.3% were migrant children. The prevalence of caries among the children in multi-beneficial kindergartens was 78.3%, and the mean number of dmft was 5.73 ± 5.00. The prevalence of caries was 81.7% for migrant children and 74.6% for resident children (p = 0.060). No significant difference was found in the mean numbers of DMFT between migrant children and resident children (5.96 ± 4.81 vs. 5.47 ± 5.20, p = 0.139). There were significant differences in the frequency of tooth brushing (p = 0.023) and parental help with tooth brushing (p = 0.008), typical use of fluoride (p = 0.012), regular dental check-ups (p = 0.003) and experience of dental fillings for caries (p < 0.001) between migrant and resident children. The multivariate logistic regression analysis showed that among the children with caries, the proportion of resident children who had regular dental check-ups was 1.720 times higher than that of migrant children (95% CI = 1.155 ~ 2.560), and resident children were more likely to have caries filled than migrant children (OR = 3.313, 95% CI = 1.585 ~ 6.927).

Conclusion
Oral health status and oral health behaviours were poor among children in multi-beneficial kindergartens in Nanning, China, and migration might be a significant predictive indicator for the poor utilization of dental care services by children. The government departments should make special policy to promote the children’s oral health in multi-beneficial kindergartens, and invest more to cover the migrant children’s utilization of oral health services.

Published: July 2023

Abstract
Background
Primary failure of tooth eruption (PFE) is a rare autosome genetic disorder that causes open bite. This work aimed to report a small family of PFE(OMIM: # 125,350) with a novel PTH1R variant. One of the patients has a rare clinical phenotype of the anterior tooth involved only.

Case presentation
The proband was a 13-year-old young man with an incomplete eruption of the right upper anterior teeth, resulting in a significant open-bite. His left first molar partially erupted. Family history revealed that the proband’s 12-year-old brother and father also had teeth eruption disorders. Genetic testing found a novel PTH1R variant (NM_000316.3 c.1325-1336del), which has never been reported before. The diagnosis of PFE was based on clinical and radiographic characteristics and the result of genetic testing. Bioinformatic analysis predicted this variant would result in the truncation of the G protein-coupled receptor encoded by the PTH1R, affecting its structure and function.

Conclusion
A novel PTH1R variant identified through whole-exome sequencing further expands the mutation spectrum of PFE. Patients in this family have different phenotypes, which reflects the characteristics of variable phenotypic expression of PFE.

AbstractContextGranulosa cells (GCs) that surround oocytes in mammalian reproduction play an active role in oocyte differentiation through proliferation and energy production.AimsThis study aimed to investigate the characteristics of the energy metabolism of ovarian GCs and the influence of GCs on the early embryonic development in polycystic ovary syndrome (PCOS).MethodsThe clinical characteristics and in vitro fertilization-embryo transfer treatment outcomes of 39 patients with PCOS and 68 patients with simple tubal factor infertility who underwent controlled ovarian hyperstimulation were analyzed and summarized. The mitochondrial function and glucose metabolism level of the GCs were determined, as well as the content of oxidative stress markers in the follicular fluid (FF) of patients with and without PCOS.Key resultsWhen compared to the non-PCOS group, patients with PCOS had a significantly increased number of retrieved oocytes but a significantly decreased number of high-quality embryos, available embryos, and high-quality blastocyst formation (P < 0.05). Furthermore, the mitochondrial membrane potential, adenosine triphosphate level, and mitochondrial DNA (mtDNA) copy number decreased in the GCs, whereas the levels of reactive oxygen species increased (P < 0.01). The levels of malondialdehyde and 8-oxo-deoxyguanosine (8-OHdG) in the follicular fluid (FF) of the patients with PCOS were higher than those of the control group (P < 0.05), and superoxide dismutase was increased by compensation(P < 0.05).In the PCOS group, the expressions ofGLUT1,LDHA, andPFKPwere lower than those in the non-PCOS group, and glucose levels were higher.ConclusionsThe low oocyte competence of PCOS may be associated with mitochondrial dysfunction and abnormal glycolysis.ImplicationsThis research offers explanations for the possible connections influencing human ovarian folliculogenesis.
Application of pressure–state–response approach for developing criteria and indicators of ecological health assessment of wetlands: a multi-temporal study in Ichhamati floodplains, India
Authors: Gayen Jibananda , Datta Debajit 
Published: July 2023

Abstract
Background
Tropical floodplain wetlands are among the most disturbed and intensively harvested ecosystems. Their sustainable management is often hindered due to the lack of comprehensive, coherent, and standardized assessment frameworks of wetland ecological health (WEH). In this study, a set of appropriate criteria and indicators (C&I) of WEH assessment was developed and tested on seven wetlands of River Ichhamati, eastern India.

Methods
Based on the pressure–state–response (PSR) approach, evaluation indicators representing ecological, socio-economic, and institutional sustainability issues of floodplain wetland systems were either selected or formulated through literature survey and stakeholder consensus. Weights of indicators were assigned by the entropy weighting method and then used in the Technique for Order of Preference by Similarity to Ideal Solution model to determine the Euclidean distances of each wetland from the positive ideal solution and negative ideal solution. Subsequently, a comprehensive wetland ecological health index (CWEHI) was constructed from these distances to portray the condition of any PSR system component in a wetland under a fivefold classification scheme, namely ‘excellent health’ (CWEHI ≥ 0.81), ‘good health’ (0.61–0.80), ‘moderate health’ (0.41–0.60), ‘weak health’ (0.21–0.40), and ‘morbid’ (≤ 0.20).

Results
The developed C&I set contains 8 criteria and 38 indicators under pressure component, 7 criteria and 49 indicators under state component, as well as 4 criteria and 18 indicators under response component. When applied in 2016 and 2022, it was found that the Panchita and Aromdanga wetlands were continuously in weak and morbid health status, while the Madhabpur wetland always showed an excellent or good status for all components. Health of other wetlands oscillated between moderate and morbid health across assessment years and system components.

Conclusions
The developed C&I set was found to be a flexible, holistic, and refined framework that could be applied elsewhere in similar assessments with minor indicator-level adjustments. The present assessment inferred that agriculture-dominated wetlands were more affected by amplified environmental pressure than fishing-dominated wetlands. Absence of persistent water flow from main river channel, wide-spread jute-retting, agriculture-induced eutrophication, proliferation of aquatic weeds were identified as the major causes of rapid ecological deterioration.

Published: July 2023

AbstractPurposeTo compare the biomechanical behavior of vertebrae with vertebral compression fractures (VCF) treated by a novel system with pedicular anchorage (dowelplasty) versus balloon kyphoplasty.MethodsFour cadaveric spines (T12‐L5) were harvested, cleaned from soft tissues, and separated into vertebrae. Axial compressive loads were applied to each vertebra until a VCF was generated. Half of the vertebrae (n = 11) were instrumented using the “dowelplasty” system, consisting of a hollow titanium dowel anchored into the pedicle, through which a cannulated titanium nail is inserted and locked and through which cement is injected. The other half (n = 11) were instrumented using balloon kyphoplasty. Axial compressive loads were re‐applied to each vertebra until fracture. Fracture load and fracture energy were calculated from load–displacement data for the pre‐ and post‐treatment states.ResultsCompared to balloon kyphoplasty, dowelplasty granted greater net change in fracture load (373N; 95%CI,‐331–1076N) and fracture energy (755Nmm; 95%CI,‐563–2072Nmm). A sensitivity analysis was performed without L4 and L5 vertebrae from the dowelplasty group, since the length of the cannulated nails was too short for these vertebrae: compared to balloon kyphoplasty, dowelplasty granted an even greater net change in fracture load (680N; 95%CI,‐96–1457N) and fracture energy (1274Nmm; 95%CI,‐233–2781Nmm).ConclusionTreating VCFs with dowelplasty grants increased fracture load and fracture energy compared to the pre‐treatment state. Furthermore, dowelplasty grants greater improvement in fracture load and fracture energy compared to balloon kyphoplasty, which suggests that dowelplasty may be a good alternative for the treatment of VCF.Level of evidencelevel IV.

Published: July 2023

Abstract
Context
Despite high mortality rates from both communicable and non-communicable diseases, bereavement is under-researched in African countries. The 9-cell bereavement tool was designed to assist individuals to reflect on their feelings about bereavement and identify resources in families and communities to manage bereavement. This study aimed to determine the feasibility of implementing the 9-cell bereavement tool and recruitment to experimental evaluation.

Methods
A feasibility cluster randomized trial with embedded qualitative interviews was conducted in two comparable neighbourhoods in Chitungwiza, Zimbabwe. Community leaders identified potential community lay bereavement supporters (interventionists). Each community lay bereavement supporter recruited two to three recently bereaved community members (trial participants). Following baseline data collection, the communities were randomly allocated to intervention or wait-list control. Self-administered questionnaires were completed at T0 (month 0), T1 (3 months) and T2 (6 months). Grief, mental health and social support were assessed. Focus group discussions with selected interventionists described training impact and intervention processes. Quantitative and qualitative analyses were performed.

Results
Implementation of the nine-cell bereavement tool and recruitment to experimental evaluation were successful. Implementation of the tool and the recruitment of study participants were conducted within the intended timeframe of 3 weeks. In line with the suggested sample size, the study was able to recruit and retain at least 75% of the trial participants for the total duration of the study.

Conclusion
The feasibility cluster trial was successfully implemented and assessed. Through the published protocol, the literature review and the results of this study, it has been noted that there is an urgent need to carry out a full trial in this subject matter, not only as a contribution to the currently sparse literature in this regard, but for the enormous potential public health benefit in supporting and saving lives in many more under-resourced and under-supported countries.

Investigating trade-offs made by American football linebackers using tracking data
Authors: Eager Eric , Seth Tej 
Published: July 2023

Abstract
In recent years, the game of football has made a shift towards being more quantitative. With the advent of charting and tracking data, player evaluation is able to be studied from several different angles. In this paper, we build and refine two novel metrics: Bite Distance Under Expected (BDUE) and Ground Covered Over Expected (GCOE) for the evaluation of linebackers in the National Football League (NFL). Here, we show that these metrics are heavily correlated with each other, which demonstrates the trade-off linebackers have to make between being aggressive against the run and being effective when the opposing offense is using play-action. We also show that these metrics are more stable than those in the public space. Finally, we show how these metrics measure deception by opposing offenses.
The Story of the Architectural Documentation of Hagia Sophia’s Hypogeum
Authors: Diker Hasan Fırat 
Published: July 2023

Abstract
Hagia Sophia’s hypogeum is a group of subterranean Roman tomb structures located in the area between the northeastern side of the structure and the imaret (“soup kitchen”) of Hagia Sophia. Consisting of three chambers connected by a passage, the hypogeum is dated to the fourth century and older than the current Hagia Sophia. The story of the architectural documentation of the hypogeum is also interesting. As a matter of fact, exposed findings during the museum research still contribute to the dating studies of the structure. The first digital architectural visualisation of the space was made in 2020 within the documentation of the subterranean structures of Hagia Sophia. After the partial cleaning of the inner space at the end of 2021, a relatively more favourable environment allowed for its visualisation. This study presents the most recent architectural documentation of the hypogeum carried out, the first reconstruction plan proposal, and a virtual superposition of the structure with its superstructure. Completely cleaning the interior and top will enable this space to be thoroughly documented and dated. By including the narrative of the documentation story to the present, this study is expected to be the last visualisation of the hypogeum until it is completely cleaned. The lack of architecturally similar structures in Istanbul requires special attention to this subterranean structure.
A Critical Plane-Based Multiaxial High-Cycle Fatigue Criterion Considering Mean Stress and Phase Shift Effects for Hard Metals

Published: July 2023

Abstract
Based on the critical plane method, a high-cycle fatigue criterion considering the effects of the phase shift and mean stress on multiaxial fatigue strength is proposed for hard metals. When the materials obey the von Mises criterion and are subjected to proportional loading without the mean stress, the proposed criterion can be reduced to the von Mises criterion. The experimental data conducted under combined bending and torsion loading from some studies were employed to validate the applicability of the proposed criterion. The results demonstrate that the proposed criterion has good agreement with the experimental data under loading conditions with both the mean stress and phase shift effects.

Aim. To identify lipid metabolism disorders and hyperglycemia in the open population aged 30-69 in 5 cities of the Vladimir region, taking into account sex characteristics.Material and methods. The study included 1350 people (men and women aged 30-69 years), while 1174 people completed the study; the response rate was 87%. There were 424 (36,1%) men and 750 (63,9%) women among those completed the study. All participants were interviewed according to a standard questionnaire, including questions on socio-demographic status, behavioral and biological risk factors for cardiovascular diseases, as well as the presence of somatic diseases and their treatment. The blood concentrations of total cholesterol (TC), triglycerides, high-density lipoprotein (HDL) cholesterol and glucose were determined.Results. The average indicators of TC in the adult population were 5,28±0,75 mmol/l, for men and women its level was comparable. Sex differences were revealed in the average blood level of HDL-C. In the male population, its level was 1±0,11 mmol/l, and among women it was 1,14±0,14 mmol/l (p<0,001). The blood concentration of triglycerides was significantly higher compared to women — 1,8 [1,5; 2,1] mmol/l in men vs 1,7 [1,3; 2,0] mmol/l in women (p<0,035). In the examined adult population, 56,7% had an elevated TC level, while the prevalence of hypercholesterolemia among men and women was comparable — 57,8 and 55,7%, respectively. Hyperglycemia was found in 22% of all examined, while among men it was detected in every fourth, and among women in every fifth. Sex differences were significant (p=0,045). The prevalence of prediabetes among men is significantly higher compared to women — 17,2 and 11,9% (p=0,013), while the prevalence of diabetes in men and women was comparable — 7,3 and 7,6%, respectively.Conclusion. Every second participant among men and women of the Vladimir region population has hypercholesterolemia, while fasting hyperglycemia is detected in every fourth man and fifth woman. Among men, the incidence of prediabetes is 2,5 times, and among women 1,5 times higher than the prevalence of diabetes. Thus, deve­lopment of preventive interventions in a particular region of the Central Federal District should take into account the high prevalence of hyper­cholesterolemia and hyperglycemia, including early disorders of car­bohydrate metabolism.
