A Healthy Conversation Skills intervention to support changes to physical activity and dietary behaviours in community-dwelling older adults during the COVID-19 pandemic.

AIMS: Physical activity (PA) and nutrition are important determinants of health in late adulthood. However, low levels of PA and poor nutrition are common in older adults and have become more prevalent during the COVID-19 pandemic. We hypothesised that Healthy Conversation Skills could be used to support health behaviour changes beneficial for health in older adults and thus conducted a study nested within the UK Hertfordshire Cohort Study. METHODS: Between November 2019 and March 2020, 176 participants were visited at home. A trained researcher administered a questionnaire and undertook anthropometric and physical performance tests. A total of 89 participants were randomised to the control group and received a healthy living leaflet; 87 participants in the intervention group were interviewed using Healthy Conversation Skills at the initial visit with follow-up telephone calls at 1, 3, 6 and 9 months. Follow-up at 1 year by postal questionnaire assessed change in PA and diet. In total, 155 participants (79 control and 76 intervention) completed the baseline and 1-year follow-up. RESULTS: At baseline, median (lower quartile, upper quartile) age (years) was 83.1 (81.5, 85.5) and median PA time (min/day) from walking, cycling and sports was 30.0 (15.0, 60.0). In total, 95% of participants completed the intervention; the total response rate for postal questionnaires was 94%. There were no statistically significant differences in outcomes between the trial arms. In women, there was a tendency for greater increases in diet quality in the intervention group compared to the control group (p = 0.075), while among men, there was a tendency for reduced decline in self-reported physical function in the intervention group compared to the control group (p = 0.081). CONCLUSION: We have shown that it is viable to utilise Healthy Conversation Skills via telephone to promote healthier lifestyles in older adults. Larger appropriately powered studies to determine the efficacy of such an intervention are now warranted.

[Metrology analysis and thoughts of literatures on tinnitus associated with sudden deafness based on CiteSpace].

Objective: To explore the incidence of sudden deafness accompanied with tinnitus, the selection of examination protocols and treatment, and to provide reference for the establishment of new guidelines for sudden deafness. Methods: CiteSpace software was used for analysis and data mining to analyze and summarize the computer-retrieved articles on diagnostic examination and treatment of sudden deafness accompanied with tinnitus collected from CNIC, Wanfang and Web of Science databases from 2011 to 2021. Results: A total of 207 randomized controlled studies were retrieved in this study, including 121 in Chinese and 86 in English. Finally, 74 Chinese literatures and 16 English literatures were included. Among the 74 valid Chinese literatures, 64 (86.5%) were accompanied with tinnitus, 58 (78.4%) with dizziness/vertigo, 25 (33.8%) with aural fullness, 10 (13.5%) with headache, 4 (5.4%) with insomnia, 4 (5.4%) with a mixture of dizziness and tinnitus, and 2 (2.7%) with vomiting. Among the 16 English literatures, 15 (93.8%) were accompanied with tinnitus, 12 (75.0%) with vertigo, 1 (6.3%) with aural fullness, and 1 (6.3%) with a mixture of various symptoms. Among the 64 Chinese articles mentioning tinnitus, only 9 mentioned tinnitus matching tests, and 1 mentioned that the treatment for tinnitus accompanying symptoms was sound therapy and psychological counseling. The incidence rates of tinnitus accompanying four different types of sudden deafness, from low to high, are as follows: low-to-mid frequency, 82.4%; mid-to-high frequency, 90.7%; complete deafness, 92.4%; and flat type, 92.8%. Conclusion: Tinnitus is the most common accompanying symptom of sudden deafness, and tinnitus matching test is an effective evaluation method. When establishing a scientific, comprehensive, and systematic diagnosis and treatment system or guidelines for sudden deafness, attention should be paid to the diagnosis and treatment of tinnitus symptoms and their adverse psychological reactions, in order to reduce the incidence of tinnitus patients in the later stage of recovery from sudden deafness.

Automatic segmentation of high-risk clinical target volume and organs at risk in brachytherapy of cervical cancer with a convolutional neural network.

PURPOSE: This study aimed to design an autodelineation model based on convolutional neural networks for generating high-risk clinical target volumes and organs at risk in image-guided adaptive brachytherapy for cervical cancer. MATERIALS AND METHODS: A novel SERes-u-net was trained and tested using CT scans from 98 patients with locally advanced cervical cancer who underwent image-guided adaptive brachytherapy. The Dice similarity coefficient, 95th percentile Hausdorff distance, and clinical assessment were used for evaluation. RESULTS: The mean Dice similarity coefficients of our model were 80.8%, 91.9%, 85.2%, 60.4%, and 82.8% for the high-risk clinical target volumes, bladder, rectum, sigmoid, and bowel loops, respectively. The corresponding 95th percentile Hausdorff distances were 5.23mm, 4.75mm, 4.06mm, 30.0mm, and 20.5mm. The evaluation results revealed that 99.3% of the convolutional neural networks-generated high-risk clinical target volumes slices were acceptable for oncologist A and 100% for oncologist B. Most segmentations of the organs at risk were clinically acceptable, except for the 25% sigmoid, which required significant revision in the opinion of oncologist A. There was a significant difference in the clinical evaluation of convolutional neural networks-generated high-risk clinical target volumes between the two oncologists (P<0.001), whereas the score differences of the organs at risk were not significant between the two oncologists. In the consistency evaluation, a large discrepancy was observed between senior and junior clinicians. About 40% of SERes-u-net-generated contours were thought to be better by junior clinicians. CONCLUSION: The high-risk clinical target volumes and organs at risk of cervical cancer generated by the proposed convolutional neural networks model can be used clinically, potentially improving segmentation consistency and efficiency of contouring in image-guided adaptive brachytherapy workflow.

Association between non-alcoholic fatty liver disease and metabolic abnormalities in children with different weight statuses.

OBJECTIVES: Both obesity and non-alcoholic fatty liver disease (NAFLD) increase the risk of metabolic abnormalities. However, the metabolic status of children suffering from NAFLD and exhibiting various subtypes of obesity is currently unclear. We aimed to explore the association between NAFLD and metabolic abnormalities in children with different weight statuses. METHODS: We included 6086 participants aged 6-18 years from the China Child and Adolescent NAFLD Study (CCANS), all of whom had undergone ultrasonography or magnetic resonance imaging-proton density fat fraction (MRI-PDFF) to identify NAFLD and metabolic abnormalities, including hyperglycemia, high triglycerides (TG), low high-density lipoprotein cholesterol (HDL-C), high low-density lipoprotein cholesterol, high total cholesterol, and hyperuricemia. RESULTS: Among the participants, there were 2408 children with obesity and NAFLD, 174 with NAFLD, 2396 with obesity, and 1108 without obesity and NAFLD. The odds ratios (ORs) of suffering from individual metabolic abnormalities were significantly greater in children with obesity and NAFLD than in children without obesity and NAFLD, with ORs ranging from 6.23 (95% CI: 4.56, 8.53) to 1.77 (95% CI: 1.06, 2.94). The ORs of metabolic abnormalities, except for low HDL-C, were greater in children with NAFLD alone than in children without obesity or NAFLD, with ORs ranging from 4.36 (95% CI: 2.77, 6.84) to 2.08 (95% CI: 1.14, 3.78). Notably, obesity and NAFLD had a multiplicative effect on overall metabolic abnormalities, high TG levels, and low HDL-C levels. CONCLUSIONS: Children with obesity and NAFLD could be at a significantly increased risk of metabolic abnormalities. Even for children without obesity, NAFLD appears to be associated with an increased risk of experiencing a worsened metabolic status.

[Pathogenic investigation of human respiratory syncytial virus infection in kindergarten children in Tongzhou District, Beijing City in 2023].

The study focused on individuals with influenza-like symptoms (fever, cough, sore throat, runny nose, and other respiratory symptoms) in three kindergartens in Tongzhou District, Beijing City, in April 2023. Nasopharyngeal swab specimens were collected, and real-time fluorescent quantitative PCR was used to detect common respiratory pathogens in the collected specimens. Positive specimens were subjected to sequencing analysis of the highly variable region of human respiratory syncytial virus (HRSV) G protein, homology analysis and phylogenetic tree analysis. A total of 25 fever cases were collected from 3 kindergartens, aged 3-8 years old, with an age M (Q1, Q3) of 4 (3.5, 5) years old. Ten confirmed cases of HRSV positive were screened and detected using the fluorescent quantitative PCR method, with a total detection rate of 40% (10/25). Typing identification and sequencing analysis confirmed that the main epidemic type was HRSV subtype B, which was highly homologous and closely related to previous epidemic strains in the region. Through pathogen investigation and analysis, it was preliminarily determined that this epidemic was dominated by HRSV subtype B.

[Application study on the prevention and treatment of spleen aminopeptide oral solution on seasonal allergic rhinitis].

Methods: A total of 392 patients with seasonal allergic rhinitis were selected from the population of the epidemiological investigation project of allergic diseases in Hohhot, Inner Mongolia. The project was led by Department of Allergy, Beijing Shijitan Hospital, Capital Medical University, and assisted by Hohhot First Hospital from April to May 2023. The patients were randomly divided into a spleen aminopeptide group (296 cases) and control group (96 cases) at a ratio of 3∶1, and the enrollment period was from June 1 to 14, 2023. The treatment group was treated with spleen aminopeptide oral solution for 12 weeks starting from 4-6 weeks (±7 days) before the pollen dispersal period, while the control group was treated with a simulated agent of spleen aminopeptide oral solution. Both the treatment group and the control group were treated with oral antihistamines and/or nasal glucocorticoids as needed during the pollen dispersal period. Evaluate the therapeutic effect by comparing the symptom scores, drug scores and quality of life scores of the two groups, and detect the expression levels of cytokines in serum. Symptom scores, quality of life scores, drug scores and laboratory results were compared by independent sample t test/Kruskal-Wallis test and χ2 test/Fisher's exact test. Results: Compared with the control group, spleen aminopeptide treatment for 12 weeks significantly improved symptoms of nasal congestion [M(Q1,Q3):2(1, 2) vs. 2(1, 3), H=6.308, P<0.05], nasal itching [M(Q1,Q3):2(1, 2) vs. 2(1, 3), H=4.966, P<0.05], sneezing [M(Q1,Q3):2(1, 2) vs. 2(1, 3), H=5.245, P<0.05], runny nose [M(Q1,Q3):2(1, 2) vs. 2(1, 3), H=5.41, P<0.05] and tearing [M(Q1,Q3):1(0, 2) vs. 1(0, 3), H=4.664, P<0.05]. At 12 weeks of treatment, the scores of nasal symptoms and ocular symptoms in control group and experimental group were significantly increased compared with baseline (P<0.05). In experimental group, nasal congestion [M(Q1,Q3):1(0, 1) vs. 1(0, 2), H=4.042, P<0.05], eye itching/foreign body sensation/redness symptom scores [M(Q1,Q3):1(0, 2) vs. 1(0, 2), H=5.302, P<0.05] and total scores [M(Q1,Q3):4(-1, 9) vs. 5(0, 12.5), H=3.958, P<0.05] were significantly increased. The antihistamine drug score of the splenic peptide treatment group at 6 weeks were lower than that of the control group (H=4.232, P<0.05). After 12 weeks of treatment, the antihistamine drug score [M(Q1,Q3):10(0, 24) vs. 19(2, 36.5), H=6.67, P<0.05] and the total drug score [M(Q1,Q3):28.5(5, 77.5) vs. 46(6, 155.5), H=3.995, P<0.05] were significantly lower than those of the control group. The serum IL-17A levels of the treatment group were significantly lower than those of the control group after 6 weeks (0.7±1.77 vs. 0.85±1.67,H=10.08, P<0.05) and 12 weeks (0.81±1.63 vs. 0.94±1.73,H=5.196, P<0.05) of splenic aminopeptide treatment. Conclusions: Early treatment with spleen aminopeptide oral solution can significantly improve nasal and ocular symptoms of patients with seasonal allergic rhinitis, reduce the use of drugs during the onset period, and improve the quality of life. It may exert an immunomodulatory effect by reducing the expression level of IL-17A in the serum of patients. Objects: To conduct a study on the prevention and treatment of seasonal allergic rhinitis in Hohhot, Inner Mongolia, evaluate the preventive and therapeutic effects of spleen aminopeptide oral solution on seasonal allergic rhinitis, and explore its related mechanisms.

[Proteomic analysis of differentially expressed proteins in gastrointestinal neuroendocrine tumors and their liver metastasis].

Objective: To investigate the differences of protein expressions in the primary tumors, adjacent tissues, and metastatic tumors of gastrointestinal neuroendocrine neoplasms. Methods: Nine patients with gastrointestinal neuroendocrine tumors (GI-NENs) with liver metastasis who underwent surgery at the National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences from July 2015 to April 2019 were selected. The protein expressions of the primary tissues, liver metastatic tissues, and adjacent tissues were detected by the data independent acquisition (DIA) technology. P<0.05 and | log2FC|>0.5 (FC as the difference multiple) were used as the criteria to identify the differentially expressed proteins in the primary tissues vs adjacent tissues, primary tissues vs liver metastatic tissues, primary tissues with different degrees of differentiation, and liver metastatic tissues with different degrees of differentiation. The differentially expressed proteins were investigated by volcano map analysis, cluster analysis, Gene Ontology (GO) function analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Results: Compared with adjacent tissues, 85 proteins were downregulated and 42 proteins were upregulated in the primary tissues of gastric NENs. The differentially expressed proteins were mainly enriched in the biological processes related to the regulation of guanosidase triphosphate activity and the catabolism of deoxyribonucleoside monophosphate, the glycosaminoglycan biosynthesis chondroitin sulfate/dermatan sulfate, pantothenate, and CoA biosynthesis signaling pathways. 114 proteins were downregulated and 155 proteins were upregulated in the primary tissues of intestinal NENs. The differentially expressed proteins were mainly enriched in the biological processes related to glutathione metabolism and sulfur compound metabolism, collecting duct acid secretion, and taurine and hytaurine metabolism signaling pathways. Compared with the primary tissues of neuroendocrine cancers (NECs), 168 proteins were downregulated and 278 proteins were upregulated in G1-2 differentiation primary tissues. The differentially expressed proteins were significantly enriched in biological processes such as DNA metabolism and DNA replication, as well as replication, mismatch repair, and other pathways. Compared with the metastatic tissues of NECs, 95 proteins were downregulated and 97 proteins were upregulated in G1-2 differentiated metastases. The differentially expressed proteins were significantly enriched in the activity and catalytic activity of transcriptional coactivators, base excision repair, and protein efflux pathways. Compared with G1 differentiated primary tissues, 530 proteins were downregulated and 211 proteins were upregulated in G1 differentiated metastatic tissues. Compared with G2 differentiated primary lesions, 53 proteins were downregulated and 96 proteins were upregulated in G2 differentiated metastatic tissues. Compared with the primary lesions of NECs, 109 proteins were downregulated and 92 proteins were upregulated in the metastatic tissues of NECs. In G1 and G2 differentiated GI-NENs, there are many similar signal pathways enriched in differentially expressed proteins between primary lesions and metastases, while only one signal pathway enriched in differentially expressed proteins between primary and metastatic tissues of NECs is the same as that enriched in differentially expressed proteins between primary and metastatic tissues of GI-NENs, which is the drug metabolism signal pathway. The differentially expressed proteins in G1 differentiated primary and metastatic tissues were mainly expressed in cytoplasm (20.26%), mitochondria (18.67%), and nucleus (15.48%). The differentially expressed proteins in the primary and metastatic tissues of G2 differentiation were mainly expressed in the cytoplasm (20.24%), nucleus (18.25%), and cell membrane (15.08%). The differentially expressed proteins in the primary and metastatic tissues of NECs were mainly expressed in the nucleus (23.78%), cytoplasm (22.7%), and cell membrane (11.35%). Conclusion: The protein expressions of GI-NENs in the primary tissues, adjacent tissues, and metastatic tissues were significantly different in different sites and degrees of differentiation.

[A consistency comparison between next-generation sequencing and the FISH method for gene rearrangement detection in B-cell lymphomas].

Objective: To compare the consistency of lymphoma multigene detection panels based on next-generation sequencing (NGS) with FISH detection of B-cell lymphoma gene rearrangement. Methods: From January 2019 to May 2023, fusion genes detected by lymphoma-related 413 genes that targeted capture sequencing of 489 B-cell lymphoma tissues embedded in paraffin were collected from Henan Cancer Hospital, and the results were compared with simultaneous FISH detection of four break/fusion genes: BCL2, BCL6, MYC, and CCND1. Consistency was defined as both methods yielding positive or negative results for the same sample. The relationship between fusion mutation abundance in NGS and the positivity rate of cells in FISH was also analyzed. Results: Kappa consistency analysis revealed high consistency between NGS and FISH in detecting the four B-cell lymphoma-related gene rearrangement (P<0.001 for all) ; however, the detection rates of positive individuals differed for the four genes. Compared with FISH, NGS demonstrated a higher detection rate for BCL2 rearrangement, a lower detection rate for BCL6 and MYC rearrangement, and a similar detection rate for CCND1 rearrangement. No correlation was found between fusion mutation abundance in NGS and the positivity rate of cells in FISH. Conclusions: NGS and FISH detection of B-cell lymphoma gene rearrangement demonstrate overall good consistency. NGS is superior to FISH in detecting BCL2 rearrangement, inferior in detecting MYC rearrangement, and comparable in detecting CCND1 rearrangement.

[Analysis and summary of clinical characteristics of 289 patients with paroxysmal nocturnal hemoglobinuria in Zhejiang Province].

Objective: To further improve the understanding of paroxysmal nocturnal hemoglobinuria (PNH), we retrospectively analyzed and summarized the clinical characteristics, treatment status, and survival status of patients with PNH in Zhejiang Province. Methods: This study included 289 patients with PNH who visited 20 hospitals in Zhejiang Province. Their clinical characteristics, comorbidity, laboratory test results, and medications were analyzed and summarized. Results: Among the 289 patients with PNH, 148 males and 141 females, with a median onset age of 45 (16-87) years and a peak onset age of 20-49 years (57.8% ). The median lactic dehydrogenase (LDH) level was 1 142 (604-1 925) U/L. Classified by type, 70.9% (166/234) were classical, 24.4% (57/234) were PNH/bone marrow failure (BMF), and 4.7% (11/234) were subclinical. The main clinical manifestations included fatigue or weakness (80.8%, 235/289), dizziness (73.4%, 212/289), darkened urine color (66.2%, 179/272), and jaundice (46.2%, 126/270). Common comorbidities were hemoglobinuria (58.7% ), renal dysfunction (17.6% ), and thrombosis (15.0% ). Moreover, 82.3% of the patients received glucocorticoid therapy, 70.9% required blood transfusion, 30.7% used immunosuppressive agents, 13.8% received anticoagulant therapy, and 6.3% received allogeneic hematopoietic stem cell transplantation. The 10-year overall survival (OS) rate was 84.4% (95% CI 78.0% -91.3% ) . Conclusion: Patients with PNH are more common in young and middle-aged people, with a similar incidence rate between men and women. Common clinical manifestations include fatigue, hemoglobinuria, jaundice, renal dysfunction, and recurrent thrombosis. The 10-year OS of this group is similar to reports from other centers in China.

[Clinical characteristics of human parvovirus B19 infection after allogeneic stem cell transplantation].

Human parvovirus B19 (HPVB19) belongs to Parvoviridae, a genus of erythrovirus, and has been associated with various human diseases, and HPVB19 infection is one of the most important causes of refractory anemia after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This study retrospectively analyzed 24 patients with HSCT combined with HPVB19 infection to collate and summarize the clinical presentation, treatment, and regression of patients with combined HPVB19 infection after allo-HSCT and provide experience in the management of HPVB19 infection after allo-HSCT. The median age of the patients with HPVB19 infection was 25 years, and the median time of infection occurrence was +107 days after transplantation, and 22 (91.7% ) had anemia with a median hemoglobin (HGB) level of 77.5 (46-149) g/L, and 13 (54.2% ) had new-onset anemia or persistent decline in HGB. The median length of hospital stay was 19 days. Among patients with new-onset anemia or persistent decline in HGB, the mean increase in HGB after treatment with intravenous immunoglobulin and/or antiviral therapy was 15.69 g/L, and treatment was effective in 10 (76.92% ) patients. HPVB19 infection should be alerted to the development of refractory anemia after HSCT; despite the lack of specific treatment, the overall prognosis of HPVB19-infected patients is good.

[Effect of zinc oxide nanoparticles on hypoxia and pyroptosis of rat neutrophils].

Objective: To investigate the effects of zinc oxide nanoparticles (ZnO-NPs) on neutrophil hypoxia and pyroptosis through nucleotide binding of oligomeric domain-like receptor protein 3 (NLRP3) inflammasome, and to analyze the role of pyroptosis on respiratory tract inflammotion induced by ZnO-NPs. Methods: In October 2022, primary cultured neutrophils were obtained from the abdominal aortic blood of SPF adult healthy SD rats. The neutrophils were treated with ZnO-NPs solution (0, 5, 10, 20 µg/ml) at different concentrations, and hypoxia group (5% O(2)) was set up. Hypoxia and reactive oxygen species (ROS) levels were detected by flow cytometry, and the expression levels of NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), cleaved Caspase-1 were measured by Western blot. The activity of lactic dehydrogenase (LDH) in the cell supernatant was measured by coloration, and the content of interleukin-1 beta (IL-1ß) in cell culture supernatant was detected by enzyme-linked immunosorbent assay (ELISA) . Results: Compared with the control group, hypoxia and ROS levels of neutrophils in hypoxia group and ZnO-NPs groups were significantly increased (P<0.05), and NLRP3, ASC, cleaved Caspase-1 protein expression levels, LDH activity and IL-1ß content were significantly increased (P<0.05). Compared with hypoxia group, hypoxia and ROS levels of neutrophils in 5 µg/ml and 10 µg/ml ZnO-NPs groups were significantly decreased (P<0.05), NLRP3, ASC, cleaved Caspase-1 protein expression levels, LDH activity, and IL-1ß content were decreased significantly (P<0.05). There were no significant differences in hypoxia, ROS levels, ASC, cleaved Caspase-1 protein expression levels, LDH activity, and IL-1ß content between the 20 µg/ml ZnO-NPs group and the hypoxia group (P>0.05) . Conclusion: ZnO-NPs treatment may activate the NLRP3 inflammasome to induce pyroptosis of neutrophils which may be related to ROS and hypoxia.

[The dilemma and comprehensive assessment for a precise diagnosis of Alzheimer's disease].

The clinical and neuroimaging findings of Alzheimer's disease (AD) are significantly heterogeneous. There are uncertaintie in the current widely available clinical and imaging diagnosis of AD. In the era of amyloid-targeted monoclonal antibody therapy, accurate diagnosis of Alzheimer's disease is urgently needed. Positron emission tomography (PET) and cerebrospinal fluid (CSF) examination can effectively reflect the ß-amyloid and neurofibrillary tangles pathology in AD, thus effectively improving the accuracy of AD diagnosis. Understanding the value of various CSF and PET biomarkers in diagnosing/staging AD is a prerequisite for clinical application of biomarkers. The selection and interpretation of biomarkers should fully consider the clinical features and structural imaging of dementia patients, while paying attention to the degree of concordance between the clinical stages and the biological stages reflected by the biomarkers. Thus, biomarkers are expected to play more additional value in AD diagnosis and treatment.

Parent-child interaction, appetite self-regulation, and BMIz in Chinese preschoolers: a mediation analysis.

OBJECTIVES: Research on parent-child interaction (PCI) and its impact on children's weight status is a thriving study area. However, their potential pathways have not been established. This study investigated the association between PCI and children's body-mass index z score (BMIz) examining the role of appetite self-regulation (ASR) as a mediator. STUDY DESIGN: Mediation analysis. METHODS: We included children from 33 kindergartens in Wuhan with parents' consent, measuring children's height and weight, and calculating BMIz. To assess the PCI quality, we utilized the Brigance Parent-Child Interactions Scale. Additionally, children's ASR was tested by satiety responsiveness (SR) and food responsiveness (FR) using the Children's Eating Behavior Questionnaire. Quantile regression was employed to examine the PCI-BMIz association, while mediation analysis was conducted to explore ASR's mediating effect on the relationship between PCI and BMIz. RESULTS: Of 3973 children (53.88% boys) included in the analysis, the mean BMIz was 0.24 ± 1.13. The results revealed that children with poorer PCI quality have higher BMIz across all selected BMIz percentiles, except for the 5th percentile. Furthermore, these associations were significant across most percentiles, whether for boys or girls. Mediation analysis suggested that these associations were partially mediated by children's ASR (indFR = -0.026, PFR < 0.001; indSR = -0.058, PSR < 0.001), with stronger effects observed among boys. CONCLUSION: The variation in how strongly BMIz was linked to PCI across different percentiles suggests that children with poorer PCI have higher BMIz. The link is partially mediated through children's ASR. It's important to pay attention to the PCI quality in children with higher BMIz levels, especially in boys.

[Relationship between amniotic fluid inflammatory factors and pregnancy outcomes after emergency cervical cerclage].

Objective: To explore the relationship between amniotic fluid and peripheral blood inflammatory factors and the pregnancy outcomes after emergency cervical cerclage, and to identify effective indicators for predicting adverse pregnancy outcomes after the procedure. Methods: A case-control study was conducted, including pregnant women who were hospitalized at Sun Yat-sen Memorial Hospital, from January 1, 2013, to July 31, 2019, and underwent emergency cervical cerclage due to cervical dilatation at gestational age between 16 and 28 weeks. A total of 85 pregnant women who underwent amniocentesis for the detection of amniotic fluid inflammatory factors during the perioperative period were included. Based on whether their baby was perinatal death, the participants were divided into the case group (28 cases with perinatal death) and the control group (57 cases with live births). Univariate logistic regression analysis was performed to identify risk factors associated with adverse pregnancy outcomes, followed by multivariate logistic regression analysis to establish a regression model and nomogram. Results: (1) The levels of tumor necrosis factor α (TNF-α), interleukin (IL)-1ß, IL-6, IL-8, IL-10 in the amniotic fluid during the perioperative period and postoperative serum C-reactive protein (CRP) were significantly higher in the case group compared to the control group (all P<0.05). The case group underwent emergency cervical cerclage at an earlier gestational age compared to the control group, and their cervical dilation was greater than that of the control group (all P<0.05). However, there were no significant differences in the white blood cell counts, neutrophil percentage, and the level of preoperative CRP in the peripheral blood of pregnant women during the perioperative period (all P>0.05). (2) Univariate logistic regression analysis showed that the levels of amniotic fluid WBC, TNF-α, IL-1ß, IL-2 receptor (IL-2R), IL-6, IL-8, IL-10, postoperative CRP in the peripheral blood, gestational age at cerclage and cervical dilation were associated with adverse pregnancy outcomes (all P<0.05). Multivariate regression analysis indicated that only the levels of amniotic fluid WBC and TNF-α were independent risk factors for perinatal death. (3) Based on clinical practice, a multivariate logistic regression model was constructed including the levels of amniotic fluid TNF-α, WBC, gestational age at cervical cerclage, and cervical dilation. A nomogram and calibration curve were plotted, which suggested its good predictive value for adverse pregnancy outcomes. Conclusions: During the perioperative period of emergency cervical cerclage, the levels of amniotic fluid WBC, TNF-α, IL-1ß, IL-2R, IL-6, IL-8, IL-10 are associated with adverse pregnancy outcomes, with amniotic fluid WBC and TNF-α showing the closest relationship. However, there is no significant correlation between maternal peripheral hemogram during the perioperative period and adverse pregnancy outcomes. A model constructed by amniotic fluid TNF-α, WBC, cervical cerclage gestational age, and cervical dilation has a good predictive effect on adverse pregnancy outcomes.

[From exposure to control: the application of allergen component-resolved diagnosis in the clinical management of cockroach allergies].

Cockroaches are one of the most common indoor allergens worldwide, and exposure to cockroach allergens (such as the insect body, debris, and secretions) can trigger severe allergic rhinitis and(or) asthma. Currently, the World Health Organization (WHO)/International Union of Immunological Societies (IUIS) has identified 32 allergenic components in cockroaches, but none of these allergens have shown a clear immunodominance. The sensitization rate to cockroach allergens shows significant variability across different regions and populations and exhibits cross-reactivity with various invertebrates, increasing the complexity of clinical diagnosis and treatment. This article delves into the "Molecular Allergology User's Guide 2.0"(MAUG 2.0) published by the European Academy of Allergy and Clinical Immunology (EAACI) and the research progress on cockroach allergies both domestically and internationally. It elucidates the crucial role of allergen component diagnostic technology in enhancing the diagnosis and treatment of cockroach-induced allergic diseases, efficiently assisting clinicians in identifying common sensitizations and cross-reactivities, thereby offering patients more accurate diagnoses and personalized treatment plans.
