RESUMEN

Tissue wounding induces cutaneous sensory axon regeneration via hydrogen peroxide (H2O2) that is produced by the epithelial NADPH oxidase, Duox1. Sciatic nerve injury instead induces axon regeneration through neuronal uptake of the NADPH oxidase, Nox2, from macrophages. We therefore reasoned that the tissue environment in which axons are damaged stimulates distinct regenerative mechanisms. Here, we show that cutaneous axon regeneration induced by tissue wounding depends on both neuronal and keratinocyte-specific mechanisms involving H2O2 signaling. Genetic depletion of H2O2 in sensory neurons abolishes axon regeneration, whereas keratinocyte-specific H2O2 depletion promotes axonal repulsion, a phenotype mirrored in duox1 mutants. Intriguingly, cyba mutants, deficient in the essential Nox subunit, p22Phox, retain limited axon regenerative capacity but display delayed Wallerian degeneration and axonal fusion, observed so far only in invertebrates. We further show that keratinocyte-specific oxidation of the epidermal growth factor receptor (EGFR) at a conserved cysteine thiol (C797) serves as an attractive cue for regenerating axons, leading to EGFR-dependent localized epidermal matrix remodeling via the matrix-metalloproteinase, MMP-13. Therefore, wound-induced cutaneous axon de- and regeneration depend on the coordinated functions of NADPH oxidases mediating distinct processes following injury.

RESUMEN

BACKGROUND: Spontaneous intracerebral hemorrhage (ICH) is a condition associated with high mortality and morbidity. Survivors may require prolonged intubation with mechanical ventilation (MV). The aim of this study was to analyze the predictors of extubation failure and prolonged MV in patients who undergo surgical evacuation. METHODS: This retrospective study was conducted on adult patients with ICH who underwent MV for at least 48 h and survived > 14 days after surgery. The demographics, clinical characteristics, laboratory tests, and Glasgow Coma Scale score were analyzed. RESULTS: A total of 134 patients with ICH were included in the study. The average age of the patients was 60.34 ± 15.59 years, and 79.9% (n = 107) were extubated after satisfying the weaning parameters. Extubation failure occurred in 11.2% (n = 12) and prolonged MV in 48.5% (n = 65) patients. Multivariable regression analysis revealed that a white blood cell count > 10,000/mm3 at the time of extubation was an independent predictor of reintubation. Meanwhile, age and initial Glasgow Coma Scale scores were predictors of prolonged MV. CONCLUSIONS: This study provided the first comprehensive characterization and analysis of the predictors of extubation failure and prolonged MV in patients with ICH after surgery. Knowledge of potential predictors is essential to improve the strategies for early initiation of adequate treatment and prognosis assessment in the early stages of the disease.

RESUMEN

BACKGROUND: Atopic dermatitis (AD) is rising globally, with genetics and environmental factors both playing crucial roles. Dietary habits during pregnancy are linked to children's allergic disease risk. However, limited studies have explored the association between maternal vegetarian diets during pregnancy and child AD. Therefore, this study aimed to examine the relationship between maternal vegetarian diets during pregnancy and the occurrence of AD in children. METHODS: In this study, the Taiwan Birth Cohort Study (TBCS) database was used, comprising a representative national birth cohort of infants born in Taiwan in 2005. Of 24,200 mother-child pairs in the database, 20,172 completed face-to-face interviews at 6 and 18 months. Employing a 1:10 matching strategy based on maternal age, education level, and child sex, 408 mothers who followed a vegetarian diet during pregnancy were matched with 4080 nonvegetarian mothers. This resulted in a final dataset of 4488 subjects. Logistic regression was used to explore the association between maternal vegetarian diets during pregnancy and the occurrence of AD in children. RESULTS: Among the TBCS participants, there were 292 (1.8%) mothers who adhered to lacto-ovo vegetarianism and 116 (0.7%) mothers who adhered to veganism, totaling 408 (2.4%) vegetarians during pregnancy. Compared to children of nonvegetarian mothers, children of mothers who followed a vegetarian diet during pregnancy showed a lower risk of developing AD before 18 months of age (OR = 0.65, 95% CI = 0.45-0.93, p = 0.018). CONCLUSION: This study suggests that a vegetarian diet during pregnancy may lower the risk of AD in children. It is essential to carry out long-term follow-up to fully understand the impact of a mother's diet on allergic conditions.

RESUMEN

BACKGROUND AND OBJECTIVE: The purpose of our study was to explore the immediate and long-term effects of socially assistive robots (SARs) on neuropsychiatric symptoms (NPSs), behavioral and psychological symptoms of dementia (BPSD), positive emotional experiences, and social interaction in older people living with dementia. METHODS: We set keywords and used Boolean operators to search the CINAHL, Cochrane Library, EMBASE, IEEE Digital Library, MEDLINE, PsycINFO, PubMed, Web of Science, Scopus, and Chinese Electronic Periodical Service from inception to February 2022 for randomized controlled trials. The Cochrane Collaboration bias assessment tool was used to assess article quality, and RevMan 5.4.1 software was used to conduct the meta-analysis. RESULTS: A total of 14 studies were included in the meta-analysis. SARs can help people living with dementia reduce their NPS of depression and anxiety, provide happiness from positive emotional experiences, and improve their social interaction through conversation. However, there was no significant improvement in agitation behavior, overall BPSD, or quality of life in people living with dementia. In follow-up, it was found that the effect of SRT was limited. CONCLUSION: SARs can reduce depression and increase positive emotions in people living with dementia. They may also reduce the burden on healthcare workers during the COVID-19 pandemic. This research was registered on PROSPERO CRD42020169340.

RESUMEN

BACKGROUND AND OBJECTIVE: Maintaining the life satisfaction of frail middle-aged and older adults when they experience physical disability, lower activity status, or complex conditions that are related to each other is now an urgent issue. Therefore, the purpose of this study was to provide evidence for the impact of frailty in middle-aged and older adults on life satisfaction under the simultaneous occurrence and correlation of physical disability and physical activity status. METHODS: Data from the 2015 Taiwan Longitudinal Study in Ageing (TLSA) were analyzed by PROCESS in SPSS to explore three different mediation models (N = 4,421). The first was a parallel mediation model for exploring life satisfaction in middle-aged and older adults with frailty through physical disability or physical activity. The second was a serial mediation model for examining physical disability and physical activity in causal chains linked with a specific direction of flow and to test all combinations. The third was a moderated mediation model for testing whether the indirect effect of frailty status on life satisfaction through physical disability or physical activity was moderated by age stratification. RESULTS: Physical disability and physical activity partially mediated the relationship between frailty status and life satisfaction (IEOVERALL = -0.196, 95% CI: -0.255 to -0.139). The causal path with the highest indirect effect was found to be that between frailty and physical disability; increased frailty led to higher physical disability, which in turn affected physical activity, leading to lower life satisfaction (IE = 0.013, 95% CI: 0.008 to 0.019). The different stratifications by age significantly increased the mediating effect of physical activity (Index of Moderated Mediation = -0.107, SE = 0.052, 95% CI: -0.208 to -0.005) but did not reduce the mediating effect of physical disability. CONCLUSION: This study provides evidence that physical activity and physical disability influence the development of frailty. It also has a significant impact on the life satisfaction of middle-aged and older adults.

RESUMEN

Phthalates have become a matter of public health concern due to their extensive use worldwide and negative health effects. The evaluation of potential sources of phthalate exposure is crucial to design prevention strategies, especially for vulnerable populations. This study included 528 mother-child pairs in the Taiwan Mother Infant Cohort Study who were followed up at ages 3-6 years between 2016 and 2020. Each mother was interviewed by using a structured questionnaire containing questions on demographic characteristics and household environment factors, such as the use of plastic food packaging, residential visible mold, insecticide sprays, and electric mosquito repellents. Eleven phthalate metabolites were analyzed in urine samples simultaneously collected from the mother-child pairs. The phthalate metabolite urinary concentrations were higher among the children than among their mothers, except those of mono-ethyl phthalate (MEP) and mono-2-ethylhexyl phthalate (MEHP). Multiple linear regression analyses showed that urine samples collected during the summer showed higher concentrations of phthalate metabolites than those collected during the winter. Family income levels had negative associations with the concentrations of MnBP and metabolites of di-2-ethylhexyl phthalate (DEHP) in children. The use of plastic food packaging was positively associated with mono-n-butyl phthalate (MnBP) and metabolites of DEHP in mothers. Residential visible mold or mold stains were significantly associated with higher MnBP and DEHP metabolite concentrations in children. The use of insecticide sprays was positively associated with MnBP concentrations in children. Significant associations between household environmental factors and phthalate exposure were mostly found in children, potentially indicating different exposure pathways between mothers and their children. Findings from this study provide additional information for the design of prevention strategies to protect the health of children and women.

RESUMEN

Environmental exposures to mixtures of toxic chemicals have potential interaction effects that may lead to hazard index values exceeding one. However, current regulation levels, such as tolerable daily intake (TDI), are mostly based on experimental studies conducted with a single chemical compound. In this study, we assessed the relationships between melamine and di-(2-ethylhexyl) phthalate (DEHP) exposure and their coexposure with the early renal injury markers N-acetyl -D-glucosaminidase (NAG), albumin/creatinine ratio (ACR), and microalbuminuria in 1236 pregnant women. Various generalized linear models with interaction terms and Bayesian kernel machine regression models were used for the (co-)exposure response associations. We derived the benchmark dose (BMD) and the corresponding one-sided 95% confidence bound BMDL based on the estimated (covariate-adjusted) average daily intake of melamine and DEHP metabolites measured in spot urine of the women collected during the third trimester. Given a benchmark response of 0.1, the BMDL level of melamine (DEHP) exposure on NAG (ACR, microalbuminuria) was 2.67 (11.20, 4.45) µg/kg_bw/day, and it decreased to as low as 1.46 (3.83, 2.73) µg/kg_bw/day when considering coexposure to DEHP (melamine) up to the 90th percentile. Both the exposure threshold levels of melamine and DEHP for early renal injuries in pregnant women were several-fold to one order lower than the current recommended TDIs by the WHO and the US FDA and EPA and were even lower considering coexposure. Because of concurrent exposures in real-world environments, more stringent regulation levels are recommended in susceptible populations, such as pregnant women, due to potential synergistic mixture effects.

RESUMEN

BACKGROUND: Chitin is a nitrogen-containing polysaccharide that can promote wound healing and stop bleeding. This paper investigates the effects of the addition of a chitin hemostatic patch on the time to arterial hemostasis, bleeding time, and reduction of the risk of bleeding and hematoma in patients undergoing cardiac catheterization. METHODS: Databases were searched for published clinical studies. The subjects were patients who received cardiac catheterization and had a chitin hemostatic patch added at the site of arterial puncture, while the control group received routine hemostatic treatment. The research quality was evaluated using the Cochrane risk-of-bias tool, version 2.0, and the meta-analysis was carried out using RevMan software. RESULTS: After searching literature databases, five randomized controlled trials were retrieved and included in the meta-analysis. The results showed that adding a chitin hemostatic patch could shorten the time to arterial hemostasis in patients, who received cardiac catheterization (Std. Mean Difference, -0.58; P < .001). In the subgroup analysis, the grouped effect of the chitin hemostatic patch on the bleeding time showed that the bleeding time was not significantly shortened after adding a chitin hemostatic patch in patients in the experimental group (RR, 0.78). At the same time, this measure did not significantly reduce the risk of arterial bleeding (RR, 0.49) or hematoma (RR, 0.73). CONCLUSIONS: The results of the meta-analysis showed that adding a chitin hemostatic patch at the site of arterial puncture in patients undergoing cardiac catheterization significantly reduced the time to hemostasis, but did not significantly reduce the incidence of bleeding and hematoma.

RESUMEN

AIMS AND OBJECTIVES: To explore the relationships among emotional distress, cognitive function and life satisfaction in people living with type 2 diabetes mellitus (T2DM), and to verify the mediating role of cognitive function. BACKGROUND: People with T2DM face cognitive decline caused by age and disease complications. Emotional distress will reduce their life satisfaction, and cognitive function will also affect the life satisfaction, but whether cognitive function mediates the effect of emotional distress on life satisfaction has not been verified. DESIGN: A cross-sectional study. METHODS: A total of 200 people living with T2DM in the community by convenience sampling were enrolled from November-December 2018. Data collection involved a demographic and disease characteristic questionnaire, Problem Areas in Diabetes Scale, Subjective and Objective Cognitive Function Evaluation and Life Satisfaction Questionnaire. Data analysis included descriptive statistics and structural equation modelling. This report followed the STROBE guideline. RESULTS: The emotional distress and subjective memory complaints of cognitive function had a significant positive correlation, while both emotional distress and cognitive function showed significant negative correlations with life satisfaction. In addition, cognitive function completely mediated the relationship between emotional distress and life satisfaction. CONCLUSION: The cognitive function played a mediating role in life satisfaction and explains how emotional distress affects life satisfaction of people with T2DM. Therefore, it is suggested that diabetes nurses should early identify the decline of cognitive function, and to intervene at an early stage. RELEVANCE TO CLINICAL PRACTICE: This study provides opinions on the mediating factors of cognitive function. Coping strategies and supporting resources to help the T2DM people to improve their life satisfaction are suggested.

RESUMEN

BACKGROUND: The relationship between constipation and childhood nocturnal enuresis (NE) has been previously reported; however, this relationship remains controversial. The present study aimed to evaluate the association between constipation and childhood NE. METHODS: Data from the Longitudinal Health Insurance Database 2000 (LHID 2000) of Taiwan National Health Insurance Research Database from 2000 to 2013 were collected. A total of 2286 children were enrolled in this study: a case group of 1143 children aged 5-18 years who were diagnosed with NE (NE group) and an age- and sex-matched control group of 1143 children without NE. Conditional logistic regression and odds ratio (OR) for NE were used to examine the association between constipation and childhood NE. RESULTS: The prevalence of NE in the case group (NE group, aged 5-18 years) was 1.03% from 2000 to 2013. The NE group had a higher percentage of constipation in 1 year before the diagnosis of NE. After stratification for sex, both boys and girls with constipation had higher OR for NE. With stratification for age, children aged 5-12 and 7-12 years had a higher OR for NE. CONCLUSIONS: Constipation is associated with childhood NE in Taiwan, particularly in children aged 5-7 and 7-12 years.

RESUMEN

PURPOSE: To assess the complication rates following chorionic villus sampling (CVS) and midtrimester amniocentesis in Taiwan. METHODS: This is a national registry-based cohort study from Taiwan. We included all women with singleton pregnancies who received either CVS (n = 1409) or midtrimester amniocentesis (n = 250,566) during 2006-2012. We assessed preterm premature rupture of membranes (PPROM), intrauterine fetal demise (IUFD), infection and spontaneous abortion (SA) that occurred within fourteen days after the procedures. We also assessed the risks of preterm delivery and miscarriage before 24 gestational weeks after amniocentesis. These complications were collected from the Genetic Disease Database of the Ministry of Health and Welfare, Taiwan National Birth Certificate Registry, and the Taiwan National Health Insurance Database. Pearson χ2 tests were used to compare the distributions between groups. RESULTS: For patients who underwent midtrimester amniocentesis, the rates of PPROM, IUFD, infection and SA within fourteen days were 0.24%, 0.11%, 0.05%, and 0.05%, respectively. Women with a normal fetal karyotype had a preterm birth rate (<37 gestational weeks) of 9.38%. The miscarriage rate (<24 gestational weeks) was 0.68%, which was 0.22% higher than those who did not receive the invasive procedures (p < 0.0001). After CVS, the IUFD rate was 1.68%, and the SA rate within fourteen days was 0.77%. CONCLUSION: The use of our large cohort demonstrated that the procedure-related complication rates were comparable to recent review or meta-analysis. This dataset might facilitate counselling in women who consider invasive genetic diagnostic procedures.

RESUMEN

Extremophilic microalgae are primary producers in acidic habitats, such as volcanic sites and acid mine drainages, and play a central role in biogeochemical cycles. Yet, basic knowledge about their species composition and community assembly is lacking. Here, we begin to fill this knowledge gap by performing the first large-scale survey of microalgal diversity in acidic geothermal sites across the West Pacific Island Chain. We collected 72 environmental samples in 12 geothermal sites, measured temperature and pH, and performed rbcL amplicon-based 454 pyrosequencing. Using these data, we estimated the diversity of microalgal species, and then examined the relative contribution of contemporary selection (i.e., local environmental variables) and dispersal limitation on the assembly of these communities. A species delimitation analysis uncovered seven major microalgae (four red, two green, and one diatom) and higher species diversity than previously appreciated. A distance-based redundancy analysis with variation partitioning revealed that dispersal limitation has a greater influence on the community assembly of microalgae than contemporary selection. Consistent with this finding, community similarity among the sampled sites decayed more quickly over geographical distance than differences in environmental factors. Our work paves the way for future studies to understand the ecology and biogeography of microalgae in extreme habitats.

RESUMEN

The investigators aimed to explore the prevalence of depressive symptoms and associated factors among older residents with intact cognitive function in nursing homes in Taiwan. A cross-sectional descriptive and correlational research design was used. A convenience sample of 178 older residents without cognitive impairment was recruited from 36 nursing homes in Southern Taiwan. The questionnaires included demographic data; the Barthel Index, which assesses the ability to perform activities of daily living; and the Geriatric Depression Scale Short Form. Among older residents in nursing homes with intact cognitive function, 39.3% had depressive symptoms. Age, religion, previous living status, previous working status, being totally dependent in physical function, and being severely dependent in physical function were significant predictors of depressive symptoms among cognitively intact older residents. The findings highlight the critical mental healthcare issues among older residents with intact cognitive function in nursing homes. Practical strategies for preventing the occurrence of depressive symptoms and caring for those who have depressive symptoms should be developed, especially for younger or dependent older residents or residents who have never been employed, have no religious beliefs, or have lived alone before they moved into an institution.

RESUMEN

INTRODUCTION: Stoneworkers in Taiwan are exposed to occupational noise and suffer hearing impairment. A complete assessment of exposure and health effects is needed for a better understanding. MATERIALS AND METHODS: We accessed nine stone factories, monitored the environmental and personal doses of noise, analyzed the frequency spectra of noise from various machines, and recruited 55 stoneworkers and 25 administrative staff as controls for pure tone audiometry testing. RESULTS: The means (standard deviations) of 8-h time-weighted averages for environmental and personal monitoring were 85.0 (6.2) and 87.0 (5.5) dB(A), respectively, with seven of nine personal measurements being higher than the respective environmental results. The monitoring data suggest that occupational noise in the stonework environments should be a matter of great concern. Nearly all frequency spectra indicated peak values occurring between 2 and 4 kHz, which were within the bands for early noise-induced hearing loss (NIHL). The mean hearing threshold levels of the study participants were elevated in low and high frequencies (29.2 and 41.2 dB) compared to that of controls (∼25 dB for both bands). Linear regression analysis indicated no significance in the low frequencies (P = 0.207) but statistical significance in the high frequencies (P = 0.002) after adjustment for covariates, suggesting NIHL among the stoneworkers. CONCLUSION: Stoneworkers apparently display early signs of NIHL. Noises in the stonework factories with peaks in the high frequencies are harmful to hearing ability. Employers and workers have to comply with the regulation strictly to prevent further hearing damage.

RESUMEN

BACKGROUND: Developmental status at birth and subsequent obesity have been implicated in the development of childhood atopic dermatitis (AD) and allergic rhinitis (AR). METHODS: The current study analysed the cohort data of 74 688 junior high school students from a national retrospective birth cohort study in Taiwan. A random 10% sample was selected from singleton livebirths with complete data on the analytical variables of interest. Atopic disorders, including AD and AR, were assessed by questionnaires (International Study of Asthma and Allergies in Childhood). Logistic regression analyses were applied with adjustments for related risk factors. RESULTS: Among subjects mainly 13-15 years of age, the estimated prevalence was 7.6% for AD and 22.4% for AR. While the role of fetal growth in allergic disorders was less evident, the risk of developing AD and AR were both influenced by a combination of fetal growth status and adolescent body mass index (BMI). Compared with those with normal fetal growth and school-aged BMI, the risk of developing AD increased 64% among adolescents with both restricted fetal growth and high BMI (odds ratio 1.64, 95% confidence interval 1.37, 1.97). The risk for this combination was higher than that for either restricted fetal growth or high BMI alone. Nevertheless, the overall interaction between BMI and fetal growth status on atopic disorders did not reach statistical significance. CONCLUSIONS: Excessive weight gain could be an important risk factor related to developing atopic dermatitis and allergic rhinitis during adolescence, especially among infants born small for gestational age.

RESUMEN

Thermoacidophilic cyanidia (Cyanidiales) are the primary photosynthetic eukaryotes in volcanic areas. These red algae also serve as important model organisms for studying life in extreme habitats. The global biodiversity and community structure of Cyanidiales remain unclear despite previous sampling efforts. Here, we surveyed the Cyanidiales biodiversity in the Tatun Volcano Group (TVG) area in Taiwan using environmental DNA sequencing. We generated 174 rbcL sequences from eight samples from four regions in the TVG area, and combined them with 239 publicly available rbcL sequences collected worldwide. Species delimita-tion using this large rbcL data set suggested at least 20 Cyanidiales OTUs (operational taxono-mic units) worldwide, almost three times the presently recognized seven species. Results from environmental DNA showed that OTUs in the TVG area were divided into three groups: (i) dominant in hot springs with 92%-99% sequence identity to Galdieria maxima; (ii) largely distributed in drier and more acidic microhabitats with 99% identity to G. partita; and (iii) primarily distributed in cooler microhabitats and lacking identity to known cyanidia species (a novel Cyanidiales lineage). In both global and individual area analyses, we observed greater species diversity in non-aquatic than aquatic habitats. Community structure analysis showed high similarity between the TVG community and West Pacific-Iceland communities, reflecting their geographic proximity to each other. Our study is the first examination of the global species diversity and biogeographic affinity of cyanidia. Additionally, our data illuminate the influence of microhabitat type on Cyanidiales diversity and highlight intriguing questions for future ecological research.

RESUMEN

Mental health is a human right and fundamental to good personal health. Developing, planning, and implementing mental health programs is a key part of health policies worldwide. This paper uses the perspective of "mental health mainstreaming" to define mental health and explore its relationship with mental illness and psychiatric disease. Further, we apply this perspective to Taiwan's three-tiered community mental illness prevention strategy as a reference for mental health promotion and rehabilitation programs in hopes that all healthcare providers help facilitate holistic community health.

RESUMEN

BACKGROUND: The effectiveness of applying a fall-risk assessment to prevent falls in residents of long-term care facilities has not been investigated. METHODS: This prospective study enrolled elderly residents in a long-term care facility in Taiwan. Caregivers were provided with a health-status assessment and fall-risk data to enhance their fall-prevention practices. A multivariate analysis was performed to identify the factors associated with falls. RESULTS: A total of 123 subjects, including 68 and 55 for general and nursing-care models, respectively, were assessed. Their health status and risk of falls were provided to the care units to enhance their fall-prevention practices. Subjects in the nursing-care model had more dementia and more prescribed medications, worse physiologic conditions, and higher fall risk. Of them, 28 (23%) had subsequent falls. A univariate analysis showed that those with and without falls were similar in demographic characteristics, prescribed medications, physiologic function, and fall risk. There was a tendency for more falls in the nursing-care model residents (accounting for 61% of those who fell; p = 0.053). A regression analysis showed that gender (beta = 1.359; 95% confidence interval = 0.345-2.374; p = 0.010) and NPI score (beta = 0.101; 95% CI = 0.001-0.200; p = 0.047) were associated with the risk of falls. CONCLUSION: Residents at the long-term care facility had a significant risk of falls despite knowledge of their fall risk and the implementation of preventive measures. In this context of being aware of the risk, gender, and psychiatric symptoms were significantly associated with falls. Caregivers at long-term care facilities should implement further measures to prevent falls based on behavioral and psychological symptoms.

RESUMEN

Cyanate, a toxic product from the chemical oxidation treatment of highly toxic cyanide, can be converted to harmless ammonia and carbon dioxide by cyanase (EC 4.2.1.104). Cyanase from Thermomyces lanuginosus was entrapped in biomimetic silica to improve stability and reusability. After entrapment, the enzyme's activity increased by two-fold, and the residual activity after 30-min of incubation at 60 °C also increased by two-fold, compared to the free enzyme. After being stored at room temperature for 28 days, the entrapped cyanase retained 79% of the initial activity, while the free form retained 61%. The immobilized cyanase was successfully applied to cyanate detoxification; the co-entrapment of carbonic anhydrase from Sulfurihydrogenibium azorense decreased the amount of bicarbonate necessary for cyanate detoxification by 50%. The cyanate degradation retained 53% of the initial value after the co-entrapped cyanate and carbonic anhydrase were reused five times.

RESUMEN

OBJECTIVE: Bronchogenic cysts are rare congenital abnormalities, and usually asymptomatic until adulthood. We present a fetus prenatally diagnosed with a bronchogenic cyst, experiencing compression symptoms immediately after birth and underwent thoracoscopic surgery at 14 days old. CASE REPORT: A 33-year-old primigravida had a suspicion of fetal tracheal cyst. Prenatal ultrasound scan revealed a cyst near the trachea at 23 weeks' gestation. Fetal MRI defined a cystic lesion in the upper mediastinum, displacing surrounding vessels. A 3,940 g girl was delivered vaginally at 38 weeks' gestation. Shortly after birth, she developed respiratory distress, and imaging revealed a mediastinal cyst compressing the trachea and esophagus. The cyst was successfully removed through video-assisted thoracoscopic surgery at 14 days old, and pathology confirmed it as a bronchogenic cyst. Follow-up images demonstrated well-aerated lungs. At present, this 1-year-old girl develops normally without respiratory symptoms. CONCLUSION: Early detection in utero, accurate diagnosis, and timely management are crucial for bronchogenic cysts in neonates.
