RESUMO
Despite serum progesterone being a widely accepted method for luteal phase support during embryo transfer cycles, debates persist regarding the optimal strategy for guiding clinical decisions on progesterone dosages to maximize reproductive outcomes. This retrospective study explored the utility of microRNA (miRNA) biomarkers in guiding personalized progesterone dosage adjustments for frozen embryo transfer (FET) cycles in 22 in vitro fertilization (IVF) patients undergoing hormone replacement therapy. Utilizing MIRA, an miRNA-based endometrial receptivity test, we analyzed patients' miRNA expression profiles before and after progesterone dosage adjustments to determine suitable dosages and assess endometrial status. Despite patients receiving identical progesterone dosages, variations in miRNA profiles were observed in the initial cycle, and all patients presented a displaced window of implantation. Following dosage adjustments based on their miRNA profiles, 91% of patients successfully transitioned their endometrium towards the receptive stages. However, two patients continued to exhibit persistent displaced receptivity despite the adjustments. Given the evident variation in endometrial status and serum progesterone levels among individuals, analyzing miRNA expression profiles may address the challenge of inter-personal variation in serum progesterone levels, to deliver more personalized dosage adjustments and facilitate personalized luteal phase support in IVF.

PURPOSE: Tension pneumomediastinum is a rare and dangerous complication in children that can be fatal, and timely detection and treatment are critical. The aim of this study was to evaluate the safety and feasibility of computed tomography (CT) imaging-guided parasternal approach drainage for tension pneumomediastinum in children. METHODS: From June 2018 to February 2023, we consecutively enrolled 19 children with tension pneumomediastinum in our institution. A pigtail catheter was inserted into the anterior mediastinum by a CT imaging-guided parasternal approach. The catheter was connected to a negative-pressure water seal bottle to drain the pneumomediastinum. Clinical data and outcomes were summarized. RESULTS: The mean age was 3.1 ± 3.4 years, the mean weight was 15 ± 9.1 kg, the mean procedure time was 11.8 ± 2.4 min, and the drainage time was 6.7 ± 3.4 days. No major complications were identified, such as haemothorax, catheter displacement, or mediastinal infection. Effective drainage was obtained in all patients as assessed by comparing images and ventilatory parameters, and no additional surgical treatment was needed. There was no recurrence during the follow-up, which was more than 2 months. In our data, two children with COVID-19 were discharged from the hospital after effective drainage and other clinical treatment. CONCLUSION: CT-guided parasternal approach drainage is safe, minimally invasive, and effective for children with tension pneumomediastinum.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a serious congenital malformation. Given the focus on improving survival in patients with "high-risk" CDH, it is possible that risk factors for low-risk patient with CDH may not be a concern. Left heart failure leads to adverse postoperative outcomes, including the need for extracorporeal membrane oxygenation (ECMO). The purpose of this study was to explore the causes of postoperative left heart failure in the low-risk group. METHODS: A retrospective study was conducted on newborns with congenital diaphragmatic hernia who were surgically treated in our hospital from January 2018 to March 2022. Children at low risk were divided into three groups according to the intraoperative repair conditions. Group A was defined as grade A defects repaired by direct suture. Group B was defined as a grade B defect repaired by mesh. Group C was a grade B defect repaired by high-tension suture. The age, gender, weight, perioperative echocardiography, and follow-up of the patients were statistically analyzed. The risk factors of left ventricular dysfunction after surgery in neonates with low-risk congenital diaphragmatic hernia were analyzed. RESULTS: A total of 52 low-risk children were included in the study. For children in the low-risk group, there was no significant difference between the low-tension repair group and the high-tension repair group in terms of operation time, thoracic tube drainage time, hospital stay, and long-term survival rate. Group A and group B showed good left ventricular function, while group C showed more decreased left ventricular EF and LVFS (LVEF 54.06 ± 10.28, LVFS 26.94 ± 5.83, p < 0.001). On the comparison of measures of left ventricular size, the mean values of left ventricular end-diastolic diameters(LVDD) and left ventricular end-systolic diameters (LVDS) were significantly difference in group C. Univariate analysis showed that LHR, o/e LHR, operation time, and high-tension repair were the influencing factors of left ventricular dysfunction. Multivariate logistic regression analysis identified risk factors for high-tension repair. Severe left heart dysfunction occurred in 2 patients with ECMO requirement in the high-tension repair group, although the difference was not significant. CONCLUSIONS: High-tension repair is a potential cause of left ventricular dysfunction in neonates with low-risk CDH.

PURPOSE: To evaluate the safety and efficacy of single-direction lobectomy for congenital pulmonary airway malformation (CPAM), especially with incomplete pulmonary fissure (IPF). METHODS: A total of 279 patients who underwent thoracoscopic lobectomy in our hospital from January 2019 to January 2022 were analyzed. Fifty-nine children were identified as the single-direction group, and the details of the surgical application are described. The degree of pulmonary fissure completeness was quantified intraoperatively. Propensity score matching was conducted and another 59 patients who underwent conventional lobectomy were matched as the control group. RESULTS: The median age of the patients was 4.9 months and the mean body weight was 7.7 kg. For patients with complete pulmonary fissure, there were no statistical differences between two groups in terms of operative time, intraoperative blood loss, length of chest tube, and hospital stay. For patients with IPF, there were statistical differences between the single-direction group and the control group in terms of operative times (89.10 ± 7.97 min vs. 97.41 ± 7.51 min, P < 0.001), intraoperative blood loss (10.86 ± 5.36 mL vs. 14.14 ± 6.56 mL P = 0.042), and postoperative complications (P = 0.035). CONCLUSION: IPF increases the operative difficulty of thoracoscopic lobectomy for CPAM, and the single-direction lobectomy technique is an effective and safe treatment for IPF.

This study investigated miRNA and cytokine expression changes in peritoneal fluid samples of patients with advanced ovarian cancer (OVCA) after receiving hyperthermic intraperitoneal chemotherapy (HIPEC) during cytoreduction surgery (CRS). We collected samples prior to HIPEC, immediately after HIPEC, and 24/48/72 h after CRS from a total of 6 patients. Cytokine levels were assessed using a multiplex cytokine array, and a miRNA PanelChip Analysis System was used for miRNA detection. Following HIPEC, miR-320a-3p, and miR-663-a were found to be immediately down-regulated but increased after 24 h. Further, significant upregulation post-HIPEC and sustained increases in expression were detected in six other miRNAs, including miR-1290, miR-1972, miR-1254, miR-483-5p, miR-574-3p, and miR-574-5p. We also found significantly increased expression of cytokines, including MCP-1, IL-6, IL-6sR, TIMP-1, RANTES, and G-CSF. The changing expression pattern throughout the study duration included a negative correlation in miR-320a-3p and miR-663-a to cytokines including RANTES, TIMP-1, and IL-6 but a positive correlation in miRNAs to cytokines including MCP-1, IL-6sR, and G-CSF. Our study found miRNAs and cytokines in the peritoneal fluid of OVCA patients demonstrated different expression characteristics following CRS and HIPEC. Both changes in expression demonstrated correlations, but the role of HIPEC remains unknown, prompting the need for research in the future.

We performed a single-centre retrospective analysis using data from databases that were prospectively maintained in our centre between January 2019 and September 2021. Patients were divided into two groups based on the degree of pulmonary fissure completeness (PFC), using the fissure development scoring system. Patients with grades 2 or 3 PFC were considered to have incomplete pulmonary fissures and were included in Group A, and patients with grades 0 and 1 were considered to have complete pulmonary fissures and were included in Group B. The differences in demographics, perioperative characteristics and clinic outcomes between the two groups were evaluated. Multivariate logistic regression analysis was performed. A total of 213 patients with congenital lung malformation (CLM) underwent video-assisted thoracoscopic lobectomy. There were 30 patients in Group A and 183 patients in Group B. Our data showed that compared with Group B, Group A had a higher incidence of complications, especially Clavien-Dindo grade II and grade III complications. The degree of PFC was significantly correlated with the length of chest tube drainage and postoperative hospital stay. Multivariate logistic regression analysis showed that the degree of PFC could be used to predict the incidence of postoperative complications.ConclusionsThe degree of PFC is a predictor of the incidence of complications after thoracoscopic lobectomy in children with CLM.

Selective synthesis of 4-(sulfonyl)-methyl-1H-pyrazoles and (E)-4,5-dihydro-1H-pyrazoles from N-allenic sulfonylhydrazones with sulfonyl group migrations has been developed. A key feature of these reactions is that the migrations of the sulfonyl groups to different positions can be controlled by changing the Lewis acids.

BACKGROUND: The identification of the intersegmental plane (ISP) is a crucial step in segmentectomy for children with congenital pulmonary airway malformation (CPAM) due to complex anatomical variations. However, there is very limited literature available on this aspect specifically for infant. In this study, we compared the intravenous indocyanine green (ICG)-guided near-infrared fluorescence (NIRF) imaging method with the modified inflation-deflation method in terms of their perioperative characteristics and summarized our experience. METHODS: From June 2021 to November 2022, the data of 83 patients with CPAM who underwent segmentectomy by video-assisted thoracoscopic surgery were retrospectively reviewed. Twenty-eight patients underwent ICG-guided NIRF method, and 56 patients underwent the modified inflation-deflation method, characteristics and clinical outcomes were compared. RESULTS: The median age of the patients was 4.99 months (4.99 ± 1.51) with a mean body weight of 7.54 kg (7.54 ± 1.99). Both methods could accurately identify the ISP. The time taken to clearly display the ISP was shorter in ICG group than in the modified inflation-deflation group (0.18 ± 0.08 vs. 6.49 ± 1.67 min; P < 0.001), and the surgical duration (61.32 ± 14.28 vs. 88.18 ± 8.03 min; P < 0.001) were significantly shorter in the ICG group too. The two groups exhibited differences in the length of chest tube drainage (1.75 ± 1.24 vs. 2.36 ± 1.54 days; P = 0.072) and the length of hospital stay (4.61 ± 1.75 vs. 5.20 ± 3.07 days; P = 0.078), however, the differences were not statistically significant. There were no significant differences between the two groups in the blood lost and postoperative complications. At a follow-up of more than 1 year after operation, all patients had recovered well without recurrence. CONCLUSIONS: According to our experience, the ICG-guided NIRF method was safe and feasible for infants during thoracoscopic segmentectomy, it can quickly display the ISP and shorten the surgical duration compared with the modified inflation-deflation method.

BACKGROUND: Video-assisted thoracoscopic surgery is a commonly used procedure for treating congenital pulmonary airway malformation (CPAM) in infants, particularly when performing segmentectomy for segmental lesions. An innovative technique employing near-infrared fluorescence (NIRF) imaging with intravenous indocyanine green (ICG) has been utilized to delineate the intersegmental demarcation during surgery. However, no previous reports have investigated this method's application, specifically in infants. The primary aim of this study was to assess the safety and efficacy of the NIRF imaging with ICG approach in this context. METHODS: Between January 2021 and April 2022, a total of 19 consecutive segmentectomies were conducted using the NIRF imaging with ICG method to precisely identify the intersegmental plane. The results were concurrently compared with those obtained using the modified inflation-deflation technique. Comprehensive imaging and clinical data were gathered and analyzed to assess the safety and accuracy of the NIRF imaging with ICG approach. RESULTS: The study involved infants with a median age of 5.12 months (mean body weight of 8.08 g). All segmentectomies were performed successfully without any ICG-related complications. The mean operating time for the surgeries was 88.47 ± 7.94 minutes. Notably, no intraoperative conversions or significant complications were observed in any of the patients. The average hospital stay after surgery was 4.0 ± 0.82 days. During the follow-up period, extending beyond 1-year of postoperation, all patients exhibited excellent recovery with no cases of recurrence. CONCLUSIONS: Based on our experience, the NIRF imaging with intravenous ICG method proved to be both safe and effective when performing segmentectomy for infants with CPAM. Low doses of ICG did not hinder the accurate identification of the intersegmental plane.
RESUMO
Multisystem inflammatory syndrome in children (MIS-C) is an imperative pediatric inflammatory condition closely linked to COVID-19, which garners substantial attention since the onset of the pandemic. Like Kawasaki illness, this condition is characterized by an overactive immune response, leading to symptoms including pyrexia, cardiac and renal complications. To elucidate the pathogenesis of MIS-C and identify potential biomarkers, we conducted an extensive examination of specific cytokines (IL-6, IL-1ß, IL-6R, IL-10, and TNF-α) and microRNA (miRNA) expression profiles at various intervals (ranging from 3 to 20 days) in the peripheral blood sample of a severely affected MIS-C patient. Our investigation revealed a gradual decline in circulating levels of IL-6, IL-1ß, IL-10, and TNF-α following intravenous immune globulin (IVIG) therapy. Notably, IL-6 exhibited a significant reduction from 74.30 to 1.49 pg./mL, while IL-6R levels remained consistently stable throughout the disease course. Furthermore, we observed an inverse correlation between the expression of hsa-miR-596 and hsa-miR-224-5p and the aforementioned cytokines. Our findings underscore a robust association between blood cytokine and miRNA concentrations and the severity of MIS-C. These insights enhance our understanding of the genetic regulatory mechanisms implicated in MIS-C pathogenesis, offering potential avenues for early biomarker detection and therapy monitoring through miRNA analysis.
RESUMO
BACKGROUND: The impact of mRNA COVID-19 vaccines on the immunological profiles of pregnant women remains a crucial area of study. This research aims to explore the specific immunological changes triggered by these vaccines in this demographic. METHODS: In a focused investigation, we examined the effects of mRNA COVID-19 vaccination on microRNA expression in pregnant women. Key microRNAs, including miR-451a, miR-23a-3p, and miR-21-5p, were analyzed for expression changes post-vaccination. Additionally, we assessed variations in S1RBD IgG levels and specific cytokines to gauge the broader immunological response. RESULTS: Post-vaccination, significant expression shifts in the targeted microRNAs were observed. Alongside these changes, we noted alterations in S1RBD IgG and various cytokines, indicating an adapted inflammatory response. Notably, these immunological markers displayed no direct correlation with S1RBD IgG concentrations, suggesting a complex interaction between the vaccine and the immune system in pregnant women. CONCLUSIONS: Our pilot study provides valuable insights into the nuanced effects of the mRNA COVID-19 vaccine on immune dynamics in pregnant women, particularly emphasizing the role of microRNAs. The findings illuminate the intricate interplay between vaccines, microRNAs, and immune responses, enhancing our understanding of these relationships in the context of pregnancy. This research contributes significantly to the growing body of knowledge regarding mRNA COVID-19 vaccines and their specific impact on maternal immunology, offering a foundation for further studies in this vital area.
RESUMO
The ultimate aim of nuclear reprogramming is to provide stem cells or differentiated cells from unrelated cell types as a cell source for regenerative medicine. A popular route towards this is transcription factor induction, and an alternative way is an original procedure of transplanting a single somatic cell nucleus to an unfertilized egg. A third route is to transplant hundreds of cell nuclei into the germinal vesicle (GV) of a non-dividing Amphibian meiotic oocyte, which leads to the activation of silent genes in 24â h and robustly induces a totipotency-like state in almost all transplanted cells. We apply this third route for potential therapeutic use and describe a procedure by which the differentiated states of cells can be reversed so that totipotency and pluripotency gene expression are regained. Differentiated cells are exposed to GV extracts and are reprogrammed to form embryoid bodies, which shows the maintenance of stemness and could be induced to follow new directions of differentiation. We conclude that much of the reprogramming effect of eggs is already present in meiotic oocytes and does not require cell division or selection of dividing cells. Reprogrammed cells by oocytes could serve as replacements for defective adult cells in humans.

A one-pot synthesis of 3,4,5- and 1,3,5-pyrazoles from tertiary propargylic alcohols and para-tolylsulfonohydrazide has been accomplished. The pyrazoles are formed through a four-step cascade sequence, including FeCl3 -catalyzed propargylic substitution, aza-Meyer-Schuster rearrangement, base-mediated 6π electrocyclization, and thermal [1,5] sigmatropic shift. In this reaction, the 3,4,5- and 1,3,5-pyrazoles are produced selectively according to different substituents in the starting alcohols.

BACKGROUND: Thoracoscopic lobectomy is a common treatment for congenital lung malformation. Single-direction thoracoscopic lobectomy may be an effective and safe approach without the need to flip the lung over repeatedly, thus minimizing tissue trauma, but its use has not been reported in children. The purpose of this study was to evaluate the safety and efficacy of single-direction thoracoscopic lobectomy in children. METHODS: A total of 91 patients who underwent thoracoscopic lobectomy in our hospital from January 2020 to December 2020 were retrospectively analysed. According to the inclusion criteria, 21 children were identified as the single-direction group. The details of the single-direction thoracoscopic lobectomy technique are described. Another 21 patients who underwent conventional thoracoscopic lobectomy in the same period were matched using the propensity score matching and set as the control group, the clinical outcomes between the two groups were compared. RESULTS: The median age of the patients was 4.72 months (4.72 ± 0.90) with a mean body weight of 7.43 kg (7.43 ± 1.14). There were no significant differences in intraoperative blood loss (P = 0.549), operation time (P = 0.859), length of chest tube drainage (P = 0.102) and length of hospital stay (P = 0.636) between the 2 groups. No patients experienced bronchopleural fistula and conversion to thoracotomy in either group. All patients recovered well without respiratory symptoms or other complications after follow-up of more than 1 year. CONCLUSIONS: Our preliminary experience presented a series of single-direction video-assisted thoracoscopic lobectomy for children with satisfactory perioperative results.

Introduction: Congenital diaphragmatic hernia (CDH) is a structural defect caused by inadequate fusion of the pleuroperitoneal membrane that forms the diaphragm, allowing peritoneal viscera to protrude into the pleural cavity. Up to 30% of newborns with CDH require extracorporeal membrane oxygenation (ECMO) support. As with all interventions, the risks and benefits of ECMO must be carefully considered in these patients. Cardiopulmonary function has been shown to worsen rather than improve after surgical CDH repair. Even after a detailed perioperative assessment, sudden cardiopulmonary failure after surgery is dangerous and requires timely and effective treatments. Method: Three cases of cardiopulmonary failure after surgical CDH treatment in newborns have been reported. ECMO support was needed for these three patients and was successfully discontinued. We report our treatment experience. Conclusion: ECMO is feasible for the treatment of postoperative cardiopulmonary failure in newborns with CDH.
RESUMO
This pilot study explores alterations in miRNA profiles among pregnant women and their neonates upon receiving different doses of COVID-19 vaccines. Blood samples, including maternal blood (MB) and neonatal cord blood (CB), collected from five pregnant women were scrutinized using the miRNA PanelChip Analysis System, identifying nine distinct miRNAs, including miR-451a and miR-1972, which exhibited significant downregulation with two vaccine doses in both MB and CB. When compared with women vaccinated with four doses, miR-486-5p, miR-451a, and miR-1972 in the two-dose group also showed notable downregulation. Evaluating recipients of three and four doses, miR-423-5p and miR-1972 expression were significantly reduced in both MB and CB. Further comparative analysis highlighted a decline in miR-223-3p expression with increasing vaccine doses, while miR15a-5p, miR-16-5p, and miR-423-5p showed an upward trend. Notably, miR-451a, miR-1972, and miR-423-5p levels varied across doses and were associated with pathways such as "PI3K-Akt", "neurotrophin signaling", and "cortisol synthesis", suggesting the profound influence of vaccination on diverse molecular mechanisms. Our research has uncovered that escalating vaccine dosages impact miRNA profiles, which may be associated with the immunological response mechanisms in both the mother and fetus, thus indicating a substantial impact of vaccination on various molecular processes.
RESUMO
BACKGROUND: The aim of this study was to determine a predictive index for the risk of anastomotic leak following esophageal atresia anastomosis, METHODS: This article reviewed the clinical data of 74 children with esophageal atresia in Fujian Children's hospital. The risk factors for anastomotic leak were analysed, and a new predictive index was proposed. RESULTS: The incidence of anastomotic leak was 29.7% after anastomosis in 74 children with esophageal atresia. Birth weight and gap length were risk factors for anastomotic leak. Logistic regression analysis showed that birth weight (Wald 2 = 4.528, P = 0.033, OR = 0.273) was a protective factor for anastomotic leak, whereas gap length (Wald 2 = 7.057, P = 0.008, OR = 2.388) was a risk factor for anastomotic leak. The ratio of gap length to birth weight had a positive predictive effect on the occurrence of anastomotic leak (AUC = 0.732, P = 0.002). CONCLUSION: Birth weight and gap length are important predictors of anastomotic leak in esophageal atresia. Measurement of the ratio of gap length to birth weight is a helpful predictive index for anastomotic leak following the anastomosis of esophageal atresia.

Background: The present study aimed to evaluate the safety and feasibility of uniportal video-assisted thoracoscopic surgery (U-VATS) for infants with pulmonary sequestration (PS). Methods: From January 2019 to July 2020, 19 infants with PS were admitted to a provincial hospital in the Fujian Province of China. A 1.5-cm utility port was created in the fifth intercostal space at the anterior axillary line. A rigid 30° 5-mm optic thoracoscope was used for vision, and two or three instruments were utilized through the port. Surgical options include standard lobectomy, wedge resection, and resection of the extralobar sequestration. Only one intercostal space was entered, and a chest tube was inserted through the same skin incision if necessary. Results: The procedure was successful in all patients with an average operation duration of 58.3 ± 31.5 min. The length of post-operative hospital stay was 5.4 ± 1.5 days, and no post-operative deaths or serious complications were observed. The mean post-operative drainage volume was 164.6 ± 45.9 mL, and the mean post-operative thoracic tube indwelling duration was 5.5 ± 1.0 days. No intraoperative conversion, surgical mortality, or major complications were identified among the patients. Conclusion: Our preliminary experience presented a series of U-VATS lobectomy, wedge resection, and resection of the PS for infants with satisfactory perioperative results.
RESUMO
ABSTRACT: A 55-year-old man with cough, bone pain, and cervical lymphadenopathy underwent both 18F-FDG and 18F-PSMA-1007 PET/CT scans with clinical suspicion of malignant disease. Compared with 18F-FDG PET/CT, 18F-PSMA PET/CT showed intense tracer uptake in the prostate gland, lungs, osteogenic lesions, and multiple lymph nodes. Interestingly, we also found the high tracer concentration of pulmonary lymphangitic carcinomatosis, a very rare form of prostate cancer metastasis to the lung, on 18F-PSMA-1007 PET/CT images.

Purpose: The effectiveness of video-assisted thoracic surgery (VATS), even uniportal VATS (U-VATS), in the treatment of pleural empyema has recently been demonstrated. However, few works have evaluated its safety and feasibility for children. We review our experience with U-VATS in the treatment of pleural empyema for children under 11 years old. Methods: From January 2019 to December 2020, we consecutively enrolled 21 children with stage II and stage III pleural empyema in our institution. A 1.0 cm utility port was created in the 5th intercostal space at the anterior axillary line. A rigid 30°5 mm optic thoracoscope was used for vision, and two or three instruments were used through the port. Surgery was based on three therapeutic columns: removal of pleural fluid, debridement, and decortication. A chest tube was inserted through the same skin incision. Perioperative data and outcomes were summarized. Results: The procedures were successful, and satisfactory debridement of the pleural cavity was achieved in all cases. The mean age was 4.1 years (range: 6 months to 11 years old). The mean operating time was 65.7 ± 23.2 min. No intraoperative conversion or major complications were identified among the patients. The mean hospital stay was 5.0 ± 0.6 days. At a follow-up of more than 4 months after operating, all patients had recovered well without recurrence. Conclusion: According to our experience, U-VATS debridement is feasible for the surgical management of stage II and III empyema in the pediatric population. Indeed, U-VATS permits easier performance and complete debridement and decortication, with a very low risk for conversion.
