Abstract
Background
Early detection, prevention, and management of diseases associated with pregnancy and pregnancy-related conditions depend on the beginning of antenatal care contact in the first trimester. Across Africa, regional and national differences are observed in the proportion of first-trimester ANC contact and the factors contributing to it. To create a suitable intervention plan, it is crucial to overcome these differences through single standard and uniform guidelines. This can be achieved through meta-analysis and systematic reviews. Therefore, this systematic review aimed to assess the pooled prevalence of first trimester ANC contact and the factors contributing to it in Africa.

Methods
Observational studies conducted in Africa were retrieved from PubMed, Google Scholar, EMASE, CINHAL, Cochrane Library, Hinari databases and Mednar using combinations of search terms with Boolean operators. The JBI 2020 Critical Appraisal Checklist was used to assess the methodological quality of the studies. To assess publication bias, a funnel plot and Egger’s test were used to and I-squared was used to check the heterogeneity of the included studies. Data were extracted using Microsoft Excel and exported to Stata 16 software for analysis.

Results
A total of 86 articles with 224,317 study participants from 19 African countries were included. The overall pooled prevalence of first-trimester ANC contact was 37.15% (95% CI: 33.3–41.0; I2 = 99.8%). The following factors were found to be significantly associated with first-trimester ANC contact: urban residence (OR = 2.2; 95% CI: 1.5–3.1; I2 = 98.5%); women under the age of 25 (OR = 1.5; 95% CI: 1.2–1.9; I2 = 94.1%);, educational status (OR = 1.8; 95% CI: 1.4–2.2; I2 = 96.1%), primiparity (OR: 1.7; 95% CI: 1.2–2.4: I2 = 97.4%), having planned pregnancies (OR: 2.1; 95% CI: 1.5–2.7; I2 = 95.5%) and employed women (OR = 1.7; 95% CI: 1.7–2.1; I2 = 94.4%).

Conclusion
Because so few women in Africa initiate first-trimester ANC contact, it is clear that increasing maternal healthcare service uptake is still a challenge and will require significant effort to scale up the services. When working to improve maternal health in Africa, each nation's government and nongovernmental organizations should prioritize raising women's educational levels and providing pertinent information to rural women, focusing on reducing unintended pregnancies, women who live far from health facilities, women with low socioeconomic statuses, multiparous women and older women.

Recanalization of Xen45 gel stent implant occlusion using 10 − 0 nylon suture in refractory glaucoma: a case report
Authors: Zhang Yao , Xiang Haotian , Zhang Yangyang , Tang Li 
Published: October 2023

Abstract
Background
Xen Gel Stent implant is a new minimally invasive surgical treatment for glaucoma that has been proven effectiveness and safety profile. However, it may also lead to some complications. Xen Gel Stent occlusion is a relatively rare complication reported less frequently and has limited treatment experience. In our case report, we proposed a novel surgical treatment using a 10 − 0 nylon suture to successfully recanalize the occluded Xen45 Gel Stent.

Case presentation
A 16-year-old female patient had bilateral juvenile glaucoma for the past 5 years. Her right eye had undergone three glaucoma surgeries but failed. At a presentation to our hospital, the right eye’s intraocular pressure (IOP) was 30 mmHg despite applying four different active principles. Xen45 Gel Stent implant was chosen for treatment, but six days after implantation, the IOP rose to 40 mmHg as a result of an anterior chamber tip occlusion of the Xen45 Gel Stent. Nd: YAG laser shockwave therapy was attempted but failed. The patient eventually had to return to the operating room for a revision procedure. The Xen45 Gel Stent was recanalized from the ab externo by making an L-shaped conjunctival incision at the fornix base and threading a 10 − 0 nylon suture through it. The IOP was successfully controlled in the 11-month follow-up without medication.

Conclusion
If postoperative occlusion arises after Xen45 Gel Stent implantation, surgery using 10 − 0 nylon suture to recanalize Xen45 Gel Stent should be considered as a relatively safe, effective that does not require removal of Xen45 Gel Stent.

Abstract
Background
Indonesia has high numbers of preterm birth, i.e., around 600,000 preterm births annually. It imposes a significant burden on the Indonesia’s healthcare system. Indonesia therefore requires its own evidence-based reference to manage premature neonates and ex-preterm infants who subsequently survived. No long-term study on preterm infants in Indonesia has been conducted, therefore we aim to evaluate growth and development on ex-preterm infants until the pre-pubertal stage.

Methods
We at the Cipto Mangunkusumo General Hospital (CMGH) designed a prospective cohort study of preterm infants, i.e., the Cohort of Indonesian Preterm Infants for Long-term Outcomes (CIPTO) study. At least 500 subjects will be recruited with an estimation of two-year recruitment (i.e., the recruitment phase will be completed before 2024). The CIPTO study will observe long-term outcomes of ex-preterm infants, primarily on growth and developmental milestones until 8 years old. Aims of this study are to determine the ex-preterm outcomes and to generate an evidence-based reference of preterm care for ensuring optimum outcomes. The pre-specified long-term outcomes in this study are survival rates, growth outcomes, neurodevelopmental outcomes, feeding behavior, as well as hearing and vision impairments. Growth and neurodevelopmental outcomes will be assessed at 0, 2, 4, 6, 9, 12, 15, 18 and 24 months of corrected age as well as at 3, 4, 5, 6, 7 and 8 years old.

Discussion
The CIPTO study is the first prospective cohort in Indonesia focusing on preterm infants born at the CMGH. With a follow up until 8 years old, this study may provide useful insights to generate an evidence-based, Indonesia’s health care reference in managing premature infants and ensuring the optimum outcomes of ex-preterm infants.
Regional disparities in food security and depression among single-person households in the Republic of Korea
Authors: Kim Seong-Ah , Choi Seul Ki 
Published: October 2023

Abstract
Background
Single-person households constitute over 40% of all households in the Republic of Korea and are more vulnerable to food insecurity and depression than multi-person households. There is a lack of research on examining whether regional characteristics are associated with the degree of food insecurity and depression among single-person households. This study aimed to examine the regional disparities in food security and depression among single-person households in the Republic of Korea.

Methods
A total of 227,873 adults from the 2019 Korean Community Health Survey was included in the analysis. According to population density and poverty rate, the residence of the participants was classified into four regions: metropolitan areas with high population density were classified into areas with low poverty rates (Region 1) and high poverty rates (Region 2), and provinces with low population density were classified into areas with low poverty rates (Region 3) and high poverty rates (Region 4). Using a single item of household food security, those who had experienced a lack of food due to financial difficulties over the past year were classified as food insecure. Depression was measured using the Patient Health Questionnaire-9. Odds ratios and 95% confidence intervals (CI) for the risk of food insecurity and depression according to regional characteristics were calculated after adjusting for potential confounding variables.

Results
After adjusting for confounding variables, single-person households in regions with high population density, Regions 1 and 2, had 1.16 times (95% CI = 1.04–1.30) and 1.43 times (95% CI = 1.27–1.61) higher odds of food insecurity, respectively, compared to those in Region 4. Single-person households in regions with low poverty rates, Regions 1 and 3, had 1.54 times (95% CI = 1.34–1.77) and 1.21 times (95% CI = 1.01–1.46) higher odds of depression, respectively, than those in Region 4. Among those who lived alone, the middle-aged, having low income, receiving livelihood benefits, or having a low educational attainment had higher odds of experiencing both food insecurity and depression than their counterparts.

Conclusions
As the risk of food insecurity and depression in single-person households differs according to regional characteristics, local governments need to implement policies for single-person households in consideration of these distinct characteristics.

Abstract
Background
Although some factors, such as stigma and empowerment, influence the complex relationship between psychological resilience and quality of life, few studies have explored similar psychological mechanisms among patients with diabetes. Therefore, this study explored the mediating role of stigma and the moderating role of empowerment in the psychological mechanisms by which psychological resilience affects quality of life.

Methods
From June to September 2022, data were collected by multi-stage stratified sampling and random number table method. Firstly, six tertiary hospitals in Wuhu were numbered and then selected using the random number table method, resulting in the First Affiliated Hospital of Wannan Medical College being selected. Secondly, two departments were randomly selected from this hospital: endocrinology and geriatrics. Thirdly, survey points were set up in each department, and T2DM patients were randomly selected for questionnaire surveys. In addition, we used the Connor-Davidson Elasticity Scale (CD-RISC) to measure the psychological resilience of patients, and used the Stigma Scale for Chronic Illness (SSCI) to measure stigma. Empowerment was measured by the Diabetes Empowerment Scale (DES). Quality of Life was assessed by the Diabetes Quality of Life Scale (DQoL). We used SPSS (version 21) and PROCESS (version 4.1) for data analysis.

Results
(1) Psychological resilience was negatively correlated with stigma and quality of life, and positively correlated with empowerment. Stigma was positively associated with empowerment and quality of life. Empowerment was negatively correlated with quality of life. (2) The mediation analysis showed that psychological resilience had a direct predictive effect on the quality of life, and stigma partially mediated the relationship; Empowerment moderates the first half of "PR → stigma → quality of life"; Empowerment moderates the latter part of "PR → stigma → quality of life."

Conclusions
Under the mediating effect of stigma, psychological resilience can improve quality of life. Empowerment has a moderating effect on the relationship between psychological resilience and stigma, and it also has a moderating effect on the relationship between stigma and quality of life. These results facilitate the understanding of the relationship mechanisms between psychological resilience and quality of life.
Prevalence of adolescent-reported food insecurity and the determinants including coping strategies living in urban slum communities of Bangladesh during the era of COVID-19: a cross-sectional study

Published: October 2023

AbstractBackgroundAs food insecurity (FI) continues to rise worldwide especially in developing countries like Bangladesh, adolescent experience of FI have received minimal attention globally. This study aimed to identify the prevalence of adolescent-reported FI and its association with individual and socio-environmental factors as well as coping strategies amongst a sample of adolescents living in urban slum areas of Bangladesh in the times of the Coronavirus 19 (COVID-19) pandemic.MethodsA descriptive cross sectional study was conducted amongst 326 adolescents (12–18 years) living in the urban slums of Narayanganj, Dhaka from April to May, 2022. Adolescent-reported FI was assessed using a structured questionnaire adopted from Household Food Insecurity Access Scale (HFIAS). Descriptive statistics, Chi-square tests and ordinal logistic regression were used to draw inference.ResultsPrevalence of adolescent-reported FI was high (46.6% moderate and 29.8% severe). The likelihood of experiencing moderate or severe FI versus no/mild FI were 1.7 times (95% Confidence Interval (CI) [1.1, 2.5]) higher in younger adolescents and 5 times (95% CI [2.3, 12.7]) higher in unemployed youth. Socio-environmental factors determining the economic status of a household such as higher number of family members, only one earning family member, unemployed father, no household assets, food aid received by the family during pandemic and positive COVID-19 infection in family were associated with moderate and severe FI. Coping strategies such as a higher number of food seeking strategies (Adjusted Odds Ratio (AOR) 3.4, 95% CI [1.9, 5.9]), substance use (AOR 6.2, 95% CI [1.2, 31.7]) and stopping school (AOR 3.3, 95% CI [1.9, 5.7]) increased odds for moderate and severe FI. Stratified by drop-out of school status, an association between food seeking strategies and FI remained significant among those school-going, while there was no association among those dropping out of school.ConclusionThis study showed that adolescents living in urban slum communities in Bangladesh are at very high risk of FI and resort to harmful coping strategies. Our study highlights the importance of further research in adolescent reported FI and coping strategies in low to middle income countries (LMICs) and create appropriate interventions to lower FI among this group and improve their state of health and wellbeing.

Abstract
Background
Coronavirus disease 2019 (COVID-19) has posed increasing challenges to global health systems. We aimed to understand the effects of pulmonary air leak (PAL), including pneumothorax, pneumomediastinum and subcutaneous emphysema, on patients with COVID-19.

Methods
We searched PubMed, Embase and Web of Science for data and performed a meta-analysis with a random-effects model using Stata 14.0. This meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Results
Thirty-five articles were included in the meta-analysis. The data came from 14 countries and included 3,047 COVID-19 patients with PAL, 11,3679 COVID-19 patients without PAL and 361 non-COVID-19 patients with PAL. We found that the incidence of PAL was much higher in COVID-19 patients than in non-COVID-19 patients (odds ratio (OR) = 6.13, 95% CI: 2.09–18.00). We found that the group of COVID-19 patients with PAL had a longer hospital stay (standardized mean difference (SMD) = 0.79, 95% CI: 0.27–1.30) and intensive care unit (ICU) stay (SMD = 0.51, 95% CI: 0.19–0.83) and comprised more ICU (OR = 15.16, 95% CI: 6.51–35.29) and mechanical ventilation patients (OR = 5.52, 95% CI: 1.69–17.99); furthermore, the mortality rate was also higher (OR = 2.62, 95% CI: 1.80–3.82).

Conclusions
Patients with lung injuries caused by COVID-19 may develop PAL. COVID-19 patients with PAL require more medical resources, have more serious conditions and have worse clinical outcomes.

Correlation between vitamin D levels in serum and the risk of dental caries in children: a systematic review and meta-analysis
Authors: Li Zizhan , Wei Xiao , Shao Zhongjun , Liu Huan , Bai Shizhu 
Published: October 2023

Abstract
Background
Vitamin D plays a crucial role in oral health, and its deficiency is associated to significant changes in oral health diseases. We aimed to explore the relationship between levels of 25-hydroxyvitamin D (25(OH) D) and dental caries in children.

Methods
Four electronic databases were searched by two investigators including PubMed, Embase, Web of Science, and Cochrane Library. Dental caries results were presented as either prevalence or based on the index of primary and permanent teeth/surfaces with decaying, missing, and filled areas, while vitamin D levels were determined through laboratory testing. Two researchers independently selected studies, collected information, assessed risk of bias, and evaluated the study quality. Any disagreements were resolved through discussion.

Results
A total of 13 studies were included, comprising 5 cross-sectional studies, 5 cohort studies, 3 case–control studies, all of which had high methodological quality. Our meta-analysis showed that children with vitamin D deficiency had a 22% higher risk of dental caries than those with normal vitamin D levels, with a relative risk (RR) of 1.22 and a 95% confidence interval (CI) of 1.18 to 1. 25. Further subgroup analysis according to the three types of studies showed that the risk of dental caries in children with vitamin D deficiency was higher than that in normal vitamin D level group (cohort studies: 62%; cross-sectional studies, 19%; and case–control studies, 5%). Additionally, according to age, subgroup analysis also showed that the risk of dental caries in children with vitamin D deficiency was higher than that in normal vitamin D level group (permanent teeth studies, 28%; deciduous teeth studies, 68%; and mixed dentition studies 8%).

Conclusions
Levels of 25 (OH) D have been found negatively associated with dental caries in children, indicating that low vitamin D levels may be considered a potential risk factor to this dental disease.

Abstract
Background
Obstructive sleep apnea (OSA) is a globally prevalent disease with a complex diagnostic method. Severe OSA is associated with multi-system dysfunction. We aimed to develop an interpretable machine learning (ML) model for predicting the risk of severe OSA and analyzing the risk factors based on clinical characteristics and questionnaires.

Methods
This was a retrospective study comprising 1656 subjects who presented and underwent polysomnography (PSG) between 2018 and 2021. A total of 23 variables were included, and after univariate analysis, 15 variables were selected for further preprocessing. Six types of classification models were used to evaluate the ability to predict severe OSA, namely logistic regression (LR), gradient boosting machine (GBM), extreme gradient boosting (XGBoost), adaptive boosting (AdaBoost), bootstrapped aggregating (Bagging), and multilayer perceptron (MLP). All models used the area under the receiver operating characteristic curve (AUC) was calculated as the performance metric. We also drew SHapley Additive exPlanations (SHAP) plots to interpret predictive results and to analyze the relative importance of risk factors. An online calculator was developed to estimate the risk of severe OSA in individuals.

Results
Among the enrolled subjects, 61.47% (1018/1656) were diagnosed with severe OSA. Multivariate LR analysis showed that 10 of 23 variables were independent risk factors for severe OSA. The GBM model showed the best performance (AUC = 0.857, accuracy = 0.766, sensitivity = 0.798, specificity = 0.734). An online calculator was developed to estimate the risk of severe OSA based on the GBM model. Finally, waist circumference, neck circumference, the Epworth Sleepiness Scale, age, and the Berlin questionnaire were revealed by the SHAP plot as the top five critical variables contributing to the diagnosis of severe OSA. Additionally, two typical cases were analyzed to interpret the contribution of each variable to the outcome prediction in a single patient.

Conclusions
We established six risk prediction models for severe OSA using ML algorithms. Among them, the GBM model performed best. The model facilitates individualized assessment and further clinical strategies for patients with suspected severe OSA. This will help to identify patients with severe OSA as early as possible and ensure their timely treatment.
