Objective: To investigate the clinical features, treatment methods, and outcomes of fulminant myocarditis (FM) in children. Methods:The clinical data of 23 children with FM hospitalized in the First Affiliated
BackgroundPregnancy outcomes and perinatal diseases of children conceived by assisted reproductive technology (ART) and spontaneous conception (SC) are still unclear. We sought to compare the effects of ART and SC on adverse neonatal outcomes.MethodsWe included 5,913 neonates admitted to the neonatal intensive care unit (NICU) of the First Affiliated Hospital of the University of Science and Technology of China between January 2017 and December 2020. There were 1,112 (18.8%) ART pregnancies and 4,801 (81.2%) SC pregnancies. Data on maternal characteristics, comorbidities during pregnancy, and neonatal outcomes were collected and analyzed. Logistic regression models estimated the odds ratios (ORs) and 99% CIs of neonatal outcomes according to ART pregnancy. Neonatal outcomes primarily included neonatal respiratory distress syndrome (NRDS), bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), neonatal anemia, birth defects, and mortality.ResultsAmong 5,913 neonates, 485 (8.2%) had NRDS, 165 (2.8%) had BPD, 113 (1.9%) had ROP, 602 (10.2%) had neonatal anemia, and 1,112 (18.8%) were ART infants. The incidence of pregnancy-related complications, such as gestational diabetes mellitus (GDM), gestational hypothyroidism, and rheumatic immune diseases, in mothers receiving ART, was higher than that in the SC group. On multivariate analysis, ART was independently associated with NRDS (OR = 1.46; 95% CI, 1.11–1.93; p = 0.008) and ROP (OR = 1.79; 95% CI, 1.06–3.05; p = 0.031). Moreover, the association persisted after adjustment for maternal age, history of cesarean section, preconception factors, and pregnancy complications. For BPD (OR = 1.44; 95% CI, 0.91–2.27; p = 0.117) and neonatal anemia (OR = 1.12; 95% CI, 0.87–1.45; p = 0.373), the associations were attenuated substantially when adjusting for pregnancy complications. ART was associated with neither birth defects (OR = 0.98; 95% CI, 0.77–1.25; p = 0.889) nor mortality (OR = 0.98; 95% CI, 0.51–1.91; p = 0.961).ConclusionART was independently associated with adverse neonatal outcomes, including NRDS and ROP. Therefore, women who conceive by ART must improve their perinatal health and management of pregnancy-related comorbidities to enhance the quality of life of their offspring.
PurposesTo evaluate the diagnostic efficiency of metagenomics next generation sequencing (mNGS) assay in severe leptospirosis and its role on prognosis. Methods We retrospectively reviewed the medical records of patients with confirmed leptospirosis from Jan. 1, 2019 to Dec. 31, 2021 from three hospitals. Detailed data including socio-demographic data, clinical manifestations, laboratory examination results, CT images etc. were collected and analyzed. Results Six severe cases were included in this study. All were diagnosed by positive mNGS results. Three of the patients were also polymerase chain reaction examined and presented negative results. Five patients were diagnosed by mNGS assay within two or three days and antibiotics were down-graded to ceftriaxone in them. All of them were cured finally. One case, who was diagnosed by mNGS late on day 5, died. Conclusions mNGS is highly efficient in diagnosing leptospirosis and could possibly reduce the mortality rate if used at an early stage.
Background Exposure to aldehydes has been linked to adverse health outcomes such as inflammation and oxidative stress, but research on the effects of these compounds is limited. This study is aimed at assessing the association between aldehyde exposure and markers of inflammation and oxidative stress. Methods The study used data from the NHANES 2013–2014 survey (n = 766) and employed multivariate linear models to investigate the relationship between aldehyde compounds and various markers of inflammation (alkaline phosphatase (ALP) level, absolute neutrophil count (ANC), and lymphocyte count) and oxidative stress (bilirubin, albumin, and iron levels) while controlling for other relevant factors. In addition to generalized linear regression, weighted quantile sum (WQS) and Bayesian kernel machine regression (BKMR) analyses were applied to examine the single or overall effect of aldehyde compounds on the outcomes. Results In the multivariate linear regression model, each 1 standard deviation (SD) change in propanaldehyde and butyraldehyde was significantly associated with increases in serum iron levels (beta and 95% confidence interval, 3.25 (0.24, 6.27) and 8.40 (0.97, 15.83), respectively) and the lymphocyte count (0.10 (0.04, 0.16) and 0.18 (0.03, 0.34), respectively). In the WQS regression model, a significant association was discovered between the WQS index and both the albumin and iron levels. Furthermore, the results of the BKMR analysis showed that the overall impact of aldehyde compounds was significantly and positively correlated with the lymphocyte count, as well as the levels of albumin and iron, suggesting that these compounds may contribute to increased oxidative stress. Conclusions This study reveals the close association between single or overall aldehyde compounds and markers of chronic inflammation and oxidative stress, which has essential guiding value for exploring the impact of environmental pollutants on population health.
BackgroundFulminant myocarditis (FM) is an inflammatory process of the myocardium and an important cause of cardiac dysfunction in children; it is characterized by rapid onset, acute progression, and high mortality. The study sought to describe the clinical characteristics and prognostic factors in children with FM.MethodsThe study population consists of 37 consecutive patients admitted from May 2014 to December 2021 with a diagnosis of FM. According to the prognosis of children with FM during hospitalization, they were divided into “survival” group (25 cases) and “death” group (12 cases). A multivariate logistic regression analysis was performed to identify the independent predictors of in-hospital mortality in the patients, and receiver operating characteristic (ROC) curve was used to explore the predictive value of related factors.ResultsThe 37 children with FM had an average age of 8.35 ± 4.36 years old. Twenty-five of the patients survived and 12 died. Twenty-five of the children were discharged from the hospital after a series of active rescue treatments such as nutritional myocardial drugs, high-dose intravenous immunoglobulin (IVIG), glucocorticoids (GCs), temporary pacemaker (TP), extracorporeal membrane oxygenation (ECMO), and continuous renal replacement therapy (CRRT).Twelve of the children were classified into the death group because the resuscitation failed. The levels of procalcitonin (PCT), creatine kinase (CK), and myoglobin (MYO) in the death group were all higher than in the survival group (all P < 0.05), and the left ventricular ejection fraction (LVEF) in the death group was significantly lower than in the survival group (P = 0.002). The binary logistic regression analysis revealed that MYO [OR:1.006; 95%CI:(1–1.012); P = 0.045] and LVEF [OR: 0.876; 95% CI: (0.785–0.978); P = 0.019] were independent predictors of FM. ROC curve analysis showed that the area under ROC curve (AUC) of MYO and LVEF was [AUC:0.957; 95%CI:0.897~1] and [AUC:0.836; 95%CI:0.668~1], and the area under the combined ROC curve for MYO + LVEF was significantly higher than that for MYO or LVEF alone (P < 0.05), indicating that the MYO + LVEF combined diagnosis had a higher predictive value for FM.ConclusionThe levels of MYO and LVEF can be markers for prognosis of FM and can effectively evaluate the disease severity. Their combination can improve forecast accuracy; thus, the detection of the above-mentioned indexes possesses a higher value for clinical applications.
