ABSTRACT

BACKGROUND: The occurrence of orofacial Clefts (OFCs) is a congenital disease caused by many factors. According to recent studies, air pollution has a strong correlation with the occurrence of OFCs. However, there are still some controversies about the current research results, and there is no relevant research to review the latest results in recent years.

OBJECTIVE: In this paper, the authors conducted a systematic review and meta-analysis to explore the correlation between ambient air pollution and the occurrence of neonatal OFCs deformity.

METHODS: We searched Pubmed, Web of science, and Embase databases from the establishment of the database to May 2023. We included observational studies on the relationship between prenatal exposure to fine particulate matter 2.5 (PM2.5), fine particulate matter 10 (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), carbon monoxide (CO) and the risk of cleft lip (CL), cleft palate (CP), cleft lip with or without palate (CL/P). the Newcastle-Ottawa quality assessment scale (NOS) was used to evaluate the quality of the literature. Funnel plot and Egger’s regression were used to verify the publication bias. Random effect model or fixed effect model was used to estimate the combined relative risk (RR) and 95% confidence interval (95%CI).

RESULTS: A total of eleven studies were included in this study, including four cohort studies and seven case-control studies, including 22,453 cases of OFCs. Ten studies had low risk of bias and only one study had high risk of bias. Three studies reported that PM_2.5 was positively correlated with CL and CP, with a combined RR and 95%CI of 1.287(1.174,1.411) and 1.267 (1.105,1.454). Two studies reported a positive correlation between O₃ and CL, with a combined RR and 95%CI of 1.132(1.047,1.225). Two studies reported a positive correlation between PM₁₀ and CL, with a combined RR and 95%CI of 1.108 (1.017,1.206). No association was found between SO₂, CO, NO₂ exposure during pregnancy and the risk of OFCs.

CONCLUSION: The results of this study showed that there was a significant statistical correlation between exposure to PM₁₀, PM_2.5, O₃ and the risk of OFCs in the second month of pregnancy. Exposure assessment, research methods and mechanisms need to be further explored.

ABSTRACT

BACKGROUND: This study aims to explore the psychological characteristics, related emotional problems and potential NIR brain function mechanism of adolescents who refuse to attend school.

METHODS: The study included 38 adolescents (12-18 years old) who were not attending school and 35 healthy controls (12-18 years old) who are attending school regularly. Participants completed (1) general demographics, (2) Eysenck Personality Questionnaire (EPQ), (3) Zung Self-Rating Depression Scale (SDS), (4) Zung Self-Rating Anxiety Scale (SAS), and (5) Symptom Checklist-90 (SCL-90). In addition to the clinical tests, participants completed functional near-infrared spectroscopy (fNIRS). Mental health, personality, and emotional state were evaluated in both groups to explore the differences and to understand the underlying mechanisms of school refusal during adolescence.

RESULTS: Adolescents who did not attend school had higher neuroticism scores on the Eysenck Personality Questionnaire than healthy controls (p(FDR) < 0.001), introversion and concealment scores were lower than those of healthy controls (p(FDR) < 0.001), there was no significant difference in psychoticism scores between groups. SDS, SAS, SCL-90 scores and factor scores were higher than those of healthy control group (p(FDR) < 0.001), NIR functional brain imaging was different from healthy control group in the 12 and 27 channels (p(FDR) = 0.030, p(FDR) = 0.018), and no difference was found in the remaining channels (p(FDR) > 0.05). There were statistically significant differences in age and gender between the adolescents who refused school and the control group (p(FDR) < 0.001).

CONCLUSION: School refusal adolescents are relatively introverted and sensitive and need more attention in daily life. Although the adolescents’ emotional problems did not reach the diagnostic criteria of depressive disorder and anxiety disorder, their scores were still higher than those of the control group, suggesting that we should pay more attention to their emotional problems in order to better help them return to school. Using fNIRS, it was found that abnormalities in frontal lobe regions in adolescents with school refusal behaviors, which would contribute to early diagnosis and timely intervention of school refusal behaviors.

ABSTRACT

BACKGROUND AND OBJECTIVE: Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the United States. However, current evidence on the association between muscle quality and CVD is limited. This study investigates the potential association between the muscle quality index (MQI) and the prevalence of CVD and CVD-related mortality.

METHODS: Participants were selected from the National Health and Nutrition Examination Survey (NHANES) 2011-2014. Data on mortality and causes of death were obtained from the National Death Index (NDI) records through December 31, 2019. Statistical analysis used in this study, including weighted multivariable linear and logistic regression, cox regression and Kaplan-Meier (K-M) analysis, to estimate the association between MQI and all-cause mortality as well as CVD mortality. In addition, subgroup analysis was used to estimate the association between MQI and CVD subtypes, such as heart attack, coronary heart disease, angina, congestive heart failure, and stroke.

RESULTS: A total of 5,053 participants were included in the final analysis. Weighted multivariable linear regression models revealed that a lower MQI.total level was independently associated with an increased risk of CVD development in model 3, with t value =-3.48, 95%CI: (-0.24, -0.06), P = 0.002. During 5,053 person-years of 6.92 years of follow-up, there were 29 deaths from CVD. Still, the association between MQI.total and CVD mortality, as well as all-cause mortality did not reach statistical significance in the fully adjusted model (HR = 0.58, 95% CI: 0.21-1.62, P = 0.30; HR = 0.91, 95% CI:0.65,1.28, P = 0.59, respectively). Subgroup analysis confirmed that MQI.total was negatively associated with congestive heart failure (OR = 0.35, 95% CI = 0.18,0.68, P = 0.01).

CONCLUSION: This study highlights the potential of MQI as a measure of muscle quality, its negative correlation with congestive heart failure (CHF). However, MQI was not very useful for predicting the health outcomes such as CVD and mortality. Therefore, more attention should be paid to the early recognition of muscle weakness progression in CHF. Further studies are needed to explore more effective indicator to evaluate the association between muscle quality and health outcomes.

ABSTRACT

BACKGROUND: Diabetes has become a prominent global public health problem, which is an important cause of death, disease burden, and medical and health economic burden. Previous studies have reported that majority of persons diagnosed with diabetes later presented with psychological and mental health diseases. The study aimed to explore the mediation role of anxiety on social support and depression among diabetic patents in elderly caring social organizations (SOs).

METHODS: A multi-stage stratified cluster random sampling method was used in this cross-sectional study, and a questionnaire consisting of demographic questionnaire, MSPSS, GAD-7, and CES-D-10 was utilized to gather data. SPSS 22.0 and MPLUS 7.4 were used for statistical analysis. Spearman correlation analysis was employed to investigate correlations of key variables. A generalized linear model was used to exam factors associated with depression. Finally, the mediation effect among study variables was investigated by structural equation modeling (SEM).

RESULTS: The average scores of social support, anxiety, and depression were 58.41 ± 14.67, 2.95 ± 3.95, and 7.24 ± 5.53, respectively. The factors of gender, social support, and anxiety were identified as significantly influential factors related to depression among diabetic patients in elderly caring SOs. The effect of social support on depression was significantly mediated by anxiety (β = -0.467, 95%CI: -0.813 to -0.251). Furthermore, anxiety partially mediated the relationship between family support and depression (β = -0.112, 95%CI: -0.229 to -0.012), and anxiety functioned as a complete mediator in the effect of significant others’ support and depression (β = -0.135, 95%CI: -0.282 to -0.024).

CONCLUSIONS: The indirect effect of social support on depression through anxiety among diabetic patients in elderly caring SOs was elucidated. Social support played a key role in maintaining and regulating their mental health, particularly from family and significant others. Social support provided by both family and significant others exerted an important influence on maintaining and regulating their mental health. In light of this pathway, the elderly caring SOs should enhance the magnitude of social support from these two sources, thereby diminishing the likelihood of experiencing anxiety and depression.

ABSTRACT

BACKGROUND: Primary headache disorder is a known risk factor for stroke in women and usually improves during the first trimester of pregnancy. However, despite this, some women develop headaches during pregnancy (G-HA), and the effect of this headache on subsequent stroke is unknown. In this study, we evaluated the association between G-HA and stroke after delivery in women.

METHODS: Based on the Korean National Health Insurance Service database, we included women hospitalized for delivery between 2012 and 2013. G-HA was defined as a headache diagnosed during pregnancy. Primary outcome was any stroke that occurred during the observational periods from delivery to December 31, 2020. All diseases were identified based on data registered in the database using the International Classification of Disease-10^th Revision-Clinical Modification codes.

RESULTS: Of 906,187 pregnant women, G-HA was found in 56,813 (6.3%). During the observational periods, the G-HA ( +) group had a significantly higher risk of any stroke [adjusted hazard ratio (aHR) = 1.59, 95% confidence interval (CI): 1.30-1.95], ischemic stroke (aHR = 1.50, 95% CI: 1.12-2.01), hemorrhagic stroke (aHR = 1.63, 95% CI: 1.23-2.15), and intracerebral hemorrhage (aHR = 1.63, 95% CI: 1.19-2.23) than the G-HA (-) group. When analyzed considering the interaction with history of headache disorder, G-HA showed a significant association with hemorrhagic stroke, but lost its effect on ischemic stroke.

CONCLUSIONS: We demonstrated that G-HA was associated with subsequent stroke occurrence after delivery. However, the relationship between G-HA and ischemic stroke is mitigated by a history of pre-pregnancy headache disorder.

ABSTRACT

PURPOSE: Individual genetic background can play an essential role in determining the development of esophageal squamous cell carcinoma (ESCC). PTPN13 and CHEK2 play important roles in the pathogenesis of ESCC. This case-control study aimed to analyze the association between gene polymorphisms and ESCC susceptibility.

METHODS: DNA was extracted from the peripheral blood of patients. The Agena MassARRAY platform was used for the genotyping. Statistical analysis was conducted using the chi-squared test or Fisher’s exact test, logistic regression analysis, and stratification analysis.

RESULTS: The ‘G’ allele of rs989902 (PTPN13) and the ‘T’ allele of rs738722 (CHEK2) were both associated with an increased risk of ESCC (rs989902: OR = 1.23, 95% CI = 1.02-1.47, p = 0.028; rs738722: OR = 1.28, 95% CI = 1.06-1.55, p = 0.011). Stratification analysis showed that SNPs (rs989902 and rs738722) were notably correlated with an increased risk of ESCC after stratification for age, sex, smoking, and drinking status. In addition, rs738722 might be associated with lower stage, while rs989902 had a lower risk of metastasis.

CONCLUSION: Our findings display that PTPN13 rs989902 and CHEK2 rs738722 are associated with an increased risk of ESCC in the Chinese Han population.

ABSTRACT

OBJECTIVE: The objective of this study was to describe the outcomes of outpatient oncological neurosurgery (OON) in a European clinical setting and to compare them with the conventional inpatient protocol.

METHODS: Patients who had undergone OON (either tumor removal or biopsy) at the authors’ center since 2019 were analyzed. A matched cohort of patients was selected from patients undergoing tumor surgery in the same period. Collected data included patient demographics, postoperative progress, specific location of the target lesion, and the procedure performed.

RESULTS: There were 18 patients in the case group and 59 patients in the control group. The outpatient surgeries had a same-day discharge rate of 89%, and all ambulatory patients successfully completed the Enhanced Recovery After Surgery program within 6.24 hours of the procedure. All ambulatory patients underwent Hospital-at-Home postoperative follow-up for an average of 4.12 days. Radiological complications were present in 11% of the case group and 8% of the control group. Postoperative neurological deficit occurred in 6% of the same-day discharge group and 3% of the control group. Among the patients in the control group, 3% suffered from postoperative seizures, whereas no seizures were observed in the case group. These differences were not statistically significant. General anesthesia-related complications were not observed in any of the patients.

CONCLUSIONS: The authors’ findings demonstrate that Enhanced Recovery After Surgery protocols and same-day discharge craniotomy for tumor resection and image-guided biopsy under general anesthesia, when patients are carefully selected, can be safely performed with excellent outcomes in a European clinical setting. The OON program proved to be a viable alternative to conventional hospitalization, showing comparable safety records and offering advantages in terms of patient recovery.

ABSTRACT

OBJECTIVE: Enhanced recovery after surgery, or the enhanced recovery protocol (ERP), introduces a contemporary concept for perioperative care within neurosurgery. In recent years, mounting evidence has highlighted the significant impact of this approach on brain tumor surgery. The authors conducted a systematic review and meta-analysis of current publications, with a primary focus on assessing the efficiency and safety of implementing ERP in the management of patients undergoing elective craniotomies for brain tumor resection.

METHODS: This study followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and was registered in the PROSPERO database. A comprehensive search of the MEDLINE, Cochrane, Scopus, and Embase databases was performed, and two independent reviewers extracted the data, assessed bias, and resolved disagreements through discussion. Primary outcomes included hospital length of stay (LOS) and hospitalization cost. The secondary outcomes were complications, including death, reoperation, readmission, intracerebral hemorrhage, CNS infection, and deep vein thrombosis. A random-effects model was used to evaluate the effects of implementing the ERP using the mean difference (MD) for primary outcomes. Heterogeneity was assessed using I2 statistics, and statistical significance was defined as p < 0.05.

RESULTS: Eight studies, including 3 randomized controlled trials, 3 prospective studies, and 2 retrospective studies, were included in this meta-analysis. The ERP group had significantly shorter LOS (MD -2.69, 95% CI -3.65 to -1.73; p < 0.00001, I2 = 87%) and lower hospitalization cost (MD -$1188 [US dollars] 95% CI -$1726 to -$650; p = 0.0008, I2 = 71%) than the non-ERP group. There were no significant differences in the incidence of perioperative complications between the two groups.

CONCLUSIONS: This study demonstrated the effectiveness of the ERP in improving postoperative outcomes for patients undergoing elective craniotomies for brain tumors. This protocol has demonstrated the ability to reduce hospital stays and costs while maintaining a low complication rate. However, the study acknowledges the presence of clinical and statistical heterogeneity among the included articles, limiting the scope of its conclusions. Further high-quality comparative studies are necessary to substantiate these findings and establish their reliability.

ABSTRACT

OBJECTIVE: Nonaccidental trauma (NAT) is a major cause of traumatic death during infancy and early childhood. Several findings are known to raise the index of clinical suspicion: subdural hematoma (SDH), retinal hemorrhage (RH), fracture, and external trauma. Combinations of certain injury types, determined via statistical frequency associations, may assist clinical diagnostic tools when child abuse is suspected. The present study sought to assess the statistical validity of the clinical triad (SDH + RH + fracture) in the diagnosis of child abuse and by extension pediatric NAT.

METHODS: A retrospective review of The University of Arizona Trauma Database was performed. All patients were evaluated for the presence or absence of the components of the clinical triad according to specific International Classification of Diseases (ICD)-10 codes. Injury type combinations included some variation of SDH, RH, all fractures, noncranial fracture, and cranial fracture. Each injury type was then correlated with the ICD-10 codes for child abuse or injury comment keywords. Statistical analysis via contingency tables was then conducted for test characteristics such as sensitivity, specificity, positive predictive value, and negative predictive value.

RESULTS: There were 3149 patients younger than 18 years of age included in the quantitative analysis, all of whom had at least one component of the clinical triad. From these, 372 patients (11.8%) had a diagnosis of child abuse. When compared to a single diagnosis of either SDH, RH, all fractures, noncranial fracture, or cranial fracture, the clinical triad had a significantly greater correlation with the diagnosis of child abuse (100% of cases) (p < 0.0001). The dyad of SDH + RH also had a significantly greater correlation with a child abuse diagnosis compared to single diagnoses (88.9%) (p < 0.0001). The clinical triad of SDH + RH + fracture had a sensitivity of 88.8% (95% CI 87.6%-89.9%), specificity of 100% (95% CI 83.9%-100%), and positive predictive value of 100% (95% CI 99.9%-100%). The dyad of SDH + RH had a sensitivity of 89.1% (95% CI 87.9%-90.1%), specificity of 88.9% (95% CI 74.7%-95.6%), and positive predictive value of 99.9% (95% CI 99.6%-100%). All patients with the clinical triad were younger than 3 years of age.

CONCLUSIONS: When SDH, RH, and fracture were present together, child abuse and by extension pediatric NAT were highly likely to have occurred.
