BACKGROUND AND OBJECTIVE

Mothers play a significant role as primary caregivers for children with congenital heart disease (CHD) within the family. Given the complex health needs of children with CHD, coping strategies are needed to deal with the challenges associated with caring for their children with the condition. Coping mechanisms encompass fostering resilience, seeking support, and maintaining a positive outlook to navigate stress, uncertainty, and obstacles throughout their child's medical journey with CHD. The objective of this study is to explore the coping strategies employed by mothers of children diagnosed with CHD in a tertiary hospital in the Philippines.

Employing a descriptive qualitative study design, data was gathered through key informant interviews utilizing a semi-structured topic guide, which aimed to explore the perspectives and experiences of mothers with children with CHDs. Ethical approval was obtained, and data collection occurred from January to March 2016. Interview transcripts were recorded, transcribed verbatim, and underwent content analysis. Themes derived from the analysis were then validated and confirmed by the study participants.

A total of 11 mothers voluntarily participated in the study. These participants expressed utilizing various coping strategies to manage their child's condition, including seeking assistance from both physicians and traditional healers, advocating for their children, receiving support from their family and friends, regulation of emotion, and prayer and faith in God.

This study sheds light on the coping mechanisms used by mothers in raising thier children with CHD, highlighting the value of spirituality and psychological support in their journey. Enhancing assistance for impacted families and advancing genetic counseling services are two benefits of incorporating these findings into healthcare practice.

BACKGROUND: Congenital heart disease (CHD) is a leading cause of birth defect-related mortality. However, more recent CHD mortality data for China are lacking. Additionally, limited studies have evaluated sex, rural-urban, and region-specific disparities of CHD mortality in China. METHODS: We designed a population-based study using data from the Dataset of National Mortality Surveillance in China between 2008 and 2021. We calculated age-adjusted CHD mortality using the sixth census data of China in 2010 as the standard population. We assessed the temporal trends in CHD mortality by age, sex, area, and region from 2008 to 2021 using the joinpoint regression model. RESULTS: From 2008 to 2021, 33,534 deaths were attributed to CHD. The period witnessed a two-fold decrease in the age-adjusted CHD mortality from 1.61 to 0.76 per 100,000 persons (average annual percent change [AAPC] = -5.90%). Females tended to have lower age-adjusted CHD mortality than males, but with a similar decline rate from 2008 to 2021 (females: AAPC = -6.15%; males: AAPC = -5.84%). Similar AAPC values were observed among people living in urban (AAPC = -6.64%) and rural (AAPC = -6.12%) areas. Eastern regions experienced a more pronounced decrease in the age-adjusted CHD mortality (AAPC = -7.86%) than central (AAPC = -5.83%) and western regions (AAPC = -3.71%) between 2008 and 2021. Approximately half of the deaths (46.19%) due to CHD occurred during infancy. The CHD mortality rates in 2021 were lower than those in 2008 for people aged 0-39 years, with the largest decrease observed among children aged 1-4 years (AAPC = -8.26%), followed by infants (AAPC = -7.01%). CONCLUSIONS CHD mortality in China has dramatically decreased from 2008 to 2021. The slower decrease in CHD mortality in the central and western regions than in the eastern regions suggested that public health policymakers should pay more attention to health resources and health education for central and western regions.

OBJECTIVES: To investigate the characteristics and clinical significance of anorectal manometry measurements in children with tethered cord syndrome (TCS) before and after surgery. METHODS: A retrospective study was conducted on 44 children with TCS treated at the Children's Hospital of Zhejiang University School of Medicine from January 2022 to September 2023. These patients were divided into effective subgroup (n=34) and non-effective subgroup (n=10) based on postoperative symptom improvement. Additionally, 34 children with functional constipation were selected as a control group. Baseline data and manometry measurements were compared between the preoperative TCS group and the control group, as well as between the non-effective and effective subgroups. RESULTS: The TCS group had lower short contraction time and defecation relaxation rate compared to the control group (P<0.05), while defecation residual pressure and maximum rectal tolerable threshold were higher than the control group (P<0.05). The length of the anal canal in the high-pressure zone in the effective subgroup was greater postoperatively than preoperatively (P<0.05), and the initial rectal sensation threshold decreased postoperatively (P<0.05). The non-effective subgroup had lower preoperative maximum rectal expulsion pressure compared to the effective subgroup (P<0.05). Postoperative rectal anal inhibition reflex values in the effective subgroup were higher than those in the non-effective subgroup (P<0.05). CONCLUSIONS There are some differences in anorectal dynamics between children with TCS and those with functional constipation. Maximum rectal expulsion pressure may be a key predictor of surgical outcomes. Surgery can alter certain defecation functions in some children.

This article reports a child with cardioaciocutaneous syndrome (CFCS) caused by a rare microdeletion of chromosome 19p13.3, and a literature review is conducted. The child had unusual facies, short stature, delayed mental and motor development, macrocephaly, and cardiac abnormalities. Whole-exome sequencing identified a 1 040 kb heterozygous deletion in the 19p13.3 region of the child, which was rated as a "pathogenic variant". This is the first case of CFCS caused by a loss-of-function mutation reported in China, which enriches the genotype characteristics of CFCS. It is imperative to enhance the understanding of CFCS in children. Early identification based on its clinical manifestations should be pursued, and genetic testing should be performed to facilitate diagnosis.

OBJECTIVES: To investigate the application of transesophageal echocar-diography assessment for mitral valve in patients with atrial septal defects undergoing repair surgery. METHODS: The study group comprised of thirty-two adult patients with atrial septal defect who underwent thoracoscopic repair surgery at the First Affiliated Hospital of the Air Force Medical University from March to September 2022. Two-dimensional and real-time three-dimensional transesophageal ultrasonography of the mitral valve were performed after anesthesia. The parameters of the mitral valve structure at the late diastolic and late systolic stages were recorded, including anteroposterior and left-right annular diameters, anterior and posterior valves lengths, the vertical distance from the coaptation point of leaflet zone 2 during systole to the annular plane (mitral valve coaptation depth) and mitral valve coaptation length. Data from 32 patients with normal intracardiac structure and no mitral valve regurgitation (control group) were also collected and compared with those of the study group. Concurrent mitral valvoplasty was performed during the atrial septal defect repair surgery for 7 patients with significant mitral valve structural abnormalities and 2 patients with significantly increased mitral regurgitation after cardiac resuscitation. The study group was followed up with transthoracic echocardiography for 2 years postoperatively. RESULTS: In the study group, 26 (81.3%) patients had varying degrees of mitral valve morphological abnormalities. Among them, 10 (31.3%) patients had short mitral valve coaptation length or depth, 12 (37.5%) patients had closure point malposition, and 4 (12.5%) patients had different bulge of anterior and posterior leaflets. Compared with the control group, the study group had significantly smaller systolic and diastolic mitral left-right annular diameter, mitral posterior valves lengths, mitral coaptation length or depth (all P<0.05), a higher pulmonary systemic flow ratio (P<0.01), and a lower maximum blood flow velocity across the mitral valve (P<0.05). After 2 years of follow-up, among the 9 patients who underwent concurrent mitral valvoplasty, the mitral valve maintained no or little regurgitation, and the average mitral valve pressure difference was less than 5 mmHg (1 mmHg=0.133 kPa). Among the 23 patients without concurrent mitral valvoplasty, 2 patients had moderate regurgitation 1 year after surgery, with a pulmonary/systemic flow ratio larger than 2.8. CONCLUSIONS Patients with large atrial septal defects often have abnormal mitral valve structure. Therefore transesophageal echocardiography is recommended for mitral valve assessment during the surgery. If significant mitral valve structural abnormalities are detected, concurrent mitral valvoplasty is recommended.

OBJECTIVE: Exposure to polycyclic aromatic hydrocarbons (PAHs) or metal(loid)s individually has been associated with neural tube defects (NTDs). However, the impacts of PAH and metal(loid) co-exposure and potential interaction effects on NTD risk remain unclear. We conducted a case-control study in China among population with a high prevalence of NTDs to investigate the combined effects of PAH and metal(loid) exposures on the risk of NTD. METHODS: Cases included 80 women who gave birth to offspring with NTDs, whereas controls were 50 women who delivered infants with no congenital malformations. We analyzed the levels of placental PAHs using gas chromatography and mass spectrometry, PAH-DNA adducts with ³²P-post-labeling method, and metal(loid)s with an inductively coupled plasma mass spectrometer. Unconditional logistic regression was employed to estimate the associations between individual exposures and NTDs. Least absolute shrinkage and selection operator (LASSO) penalized regression models were used to select a subset of exposures, while additive interaction models were used to identify interaction effects. RESULTS: In the single-exposure models, we found that eight PAHs, PAH-DNA adducts, and 28 metal(loid)s were associated with NTDs. Pyrene, selenium, molybdenum, cadmium, uranium, and rubidium were selected through LASSO regression and were statistically associated with NTDs in the multiple-exposure models. Women with high levels of pyrene and molybdenum or pyrene and selenium exhibited significantly increased risk of having offspring with NTDs, indicating that these combinations may have synergistic effects on the risk of NTDs. CONCLUSION Our findings suggest that individual PAHs and metal(loid)s, as well as their interactions, may be associated with the risk of NTDs, which warrants further investigation.

Objective To investigate the effects of folate deficiency on changes in histone H3 lysine 4 (H3K4) mono-methylation (me1)-marked enhancers and the molecular mechanism underpinning the folate deficiency-induced neural tube defects (NTD). Methods Mouse embryonic stem cells (mESCs) were cultured in the folate-free DMEM medium (folate-deficient group) and the DMEM medium containing 4 mg/L folate (normal control group),respectively.Chromatin immunoprecipitation sequencing (ChIP-seq) was performed for H3K4me1. The mouse model of folate-induced NTD was established,and transcriptome sequencing (RNA-seq) was performed for the brain tissue of fetal mice to reveal the differential expression profiles.The results were validated through real-time quantitative polymerase chain reaction (RT-qPCR).The activity of the differential peak regions of H3K4me1 was verified through the luciferase reporter assay. Results The folate content in the mESCs cultured in the folate-free medium reduced compared with that in the normal control group (P=0.008).The H3K4me1-maked enhancers in the mESCs cultured in the folate-free medium induced significant changes in intronic regions,and these changes were concentrated in metabolic and energy metabolism processes (q=9.56×10^-48,P=1.28×10^-47).The differentially expressed genes harboring H3K4me1-marked enhancers in mESCs were mainly enriched in the Wnt signaling pathway (q=0.004,P=0.004 7).ChIP-qPCR results confirmed that H3K4me1 binding decreased in the differential peak regions of the Ldlrap1 gene (P=0.008),Camta1 gene (P=0.002),and Apc2 gene (P=0.012).The H3K4 demethylase inhibitor T-448 effectively reversed the H3K4me1 binding in the differential peak regions of the aforementioned genes (P=0.01).The results of RNA-seq for the brain tissue of NTD fetal mice showed significant enrichment of the differentially expressed genes in the Wnt signaling pathway (P=1.52×10^-5).The enrichment of differential peak regions of H3K4me1-marked enhancers in Apc2,Ldlrap1,and Camta1 genes in the brain tissue also showed significant changes.The differential peak region in Apc2 exhibited transcription factor activity (P=0.020). Conclusion Folate deficiency may affect changes in H3K4me1-marked enhancers to participate in the regulation of neural tube closure genes,thereby inducing the occurrence of NTD.
