RESUMO

Bisphenol A (BPA) is a phenolic chemical that has been found to be associated with human health outcomes. It is one of the risk factors for thyroid function. Pregnancy is a vulnerable window for thyroid problems, because of the fluctuations in hormone levels. This review aimed to evaluate the association between BPA exposure and thyroid function during pregnancy. We conducted a comprehensive search of relevant databases, including PubMed, Scopus, Embase, Web of Science, and the Cochrane Library, for original studies published in English that reported data on BPA levels and thyroid-related hormone levels in pregnant women. We used the Newcastle-Ottawa Scale (NOS) to assess the methodological quality of the studies and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method to evaluate the quality of evidence. In total, 11 studies involving 6526 individuals were included in this systematic review. These studies explored fluctuations in thyroid-related hormones, including TSH, TT3, TT4, FT3, and FT4 levels, as well as the TT4/TT3 and FT4/FT3 ratios. The systematic review is to evaluate the evidences between bisphenol A exposure and thyroid-related hormones in pregnant women. We found that BPA exposure in pregnancy might disturb the homeostasis of maternal thyroid-related hormones and suggest an increased risk of hyperthyroidism. Further studies based on the findings are required to explore the underlying mechanisms and determine the potential effects of BPA exposure on thyroid function during pregnancy.

RESUMO

Ischemic stroke (IS) remains a serious threat to human health. Neuroinflammatory response is an important pathophysiological process after IS. Circular RNAs (circRNAs), a member of the non-coding RNA family, are highly expressed in the central nervous system and widely involved in regulating physiological and pathophysiological processes. This study reviews the current evidence on neuroinflammatory responses, the role of circRNAs in IS and their potential mechanisms in regulating inflammatory cells, and inflammatory factors affecting IS damage. This review lays a foundation for future clinical application of circRNAs as novel biomarkers and therapeutic targets.

RESUMO

In recent years, the global prevalence of childhood overweight and obesity has surged. Bisphenol A (BPA), prevalent in the manufacture of polycarbonate plastics and epoxy resins, is associated with this escalating obesity pattern. Both early life stages and pregnancy emerge as pivotal windows of vulnerability. This review systematically evaluates human studies to clarify the nexus between prenatal BPA exposure and offspring obesity. Our extensive literature search covered databases like PubMed, Web of Science, Cochrane Library, Embase, and Scopus, encompassing articles from their inception until July 2023. We utilized the Newcastle-Ottawa Scale (NOS) to evaluate the methodological rigor of the included studies, the Oxford Center for Evidence-Based Medicine Levels of Evidence Working Group (OCEBM) table to determine the level of the evidence, and the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) guidelines to evaluate the certainty of the evidence with statistical significance. We centered on primary studies investigating the link between urinary BPA levels during pregnancy and offspring obesity. Our analysis included thirteen studies, with participant counts ranging from 173 to 1124 mother-child dyads. Among them, eight studies conclusively linked prenatal BPA exposure to increased obesity in offspring. Evaluation metrics for the effect of prenatal BPA on offspring obesity comprised BMI z-score, waist circumference, overweight/obesity classification, aggregate skinfold thickness, body fat percentage, and more. Present findings indicate that prenatal BPA exposure amplifies offspring obesity risk, with potential effect variations by age and gender. Therefore, further research is needed to explore the causal link between prenatal BPA exposure and obesity at different developmental stages and genders, and to elucidate the underlying mechanisms.

RESUMO

OBJECTIVE: To evaluate the clinical value of Dachengqi decoction in the treatment of sepsis complication with gastrointestinal dysfunction via gastric antrum cross-sectional area (CSA) measured by bedside ultrasound. METHODS: A parallel group randomized controlled trial was conducted. A total of 80 patients with sepsis with gastrointestinal dysfunction admitted to the Second Affiliated Hospital of Nanjing University of Chinese Medicine from January 2021 to October 2022 were enrolled. According to whether patients agree to use Dachengqi decoction after admission, all patients were divided into Dachengqi decoction group (observation group) and conventional treatment group (control group) by 1 : 1 randomization, each group has 40 patients. Both groups were treated with fluid resuscitation, anti-infection, maintaining stable respiratory circulation, early nourishing feeding, promoting gastrointestinal motility, and regulating intestinal flora. The observation group was treated with Dachengqi decoction on the basis of western medicine, 30 mL decoction was taken in the morning and evening. Both groups were treated for 7 days. The CSA of the two groups was measured by bedside ultrasound before and after treatment. The gastric residual volume (GRV1 and GRV2) were calculated by formula and traditional gastric tube withdrawal method. The gastrointestinal dysfunction score, acute physiology and chronic health evaluation II (APACHE II), intraperitoneal pressure (IAP), serum preprotein (PA), albumin (Alb), white blood cell count (WBC), procalcitonin (PCT), hypersensitivity C-reactive protein (hs-CRP), length of intensive care unit (ICU) stay and incidence of aspiration were detected to evaluate the clinical efficacy of Dachengqi decoction, the correlation and advantages and disadvantages between CSA measured by bedside ultrasound and other evaluation indicators of gastrointestinal dysfunction in sepsis were also analyzed. RESULTS: There were no significant differences in the indicators before treatment between the two groups, which were comparable. In comparison with the pre-treatment period, CSA, GRV, gastrointestinal dysfunction score, APACHE II score, IAP, WBC, PCT, and hs-CRP of the two groups after treatment were significantly decreased, PA and Alb were significantly increased, and the observation group decreased or increased more significantly than the control group [CSA (cm2): 4.53±1.56 vs. 6.04±2.52, GRV1 (mL): 39.85±8.21 vs. 53.05±11.73, GRV2 (mL): 29.22±5.20 vs. 40.91±8.97, gastrointestinal dysfunction score: 0.87±0.19 vs. 1.35±0.26, APACHE II score: 11.54±3.43 vs. 14.28±3.07, IAP (cmH2O, 1 cmH2O ≈ 0.098 kPa): 9.79±2.01 vs. 13.30±2.73, WBC (×109/L): 9.35±1.24 vs. 12.35±1.36, PCT (µg/L): 3.68±1.12 vs. 6.43±1.45, hs-CRP (mg/L): 24.76±5.41 vs. 46.76±6.38, PA (mg/L): 370.29±45.89 vs. 258.33±34.58, Alb (g/L): 38.83±5.64 vs. 33.20±4.98, all P < 0.05]. The length of ICU stay (days: 10.56±3.19 vs. 14.24±3.45) and incidence of aspiration (12.5% vs. 25.0%) were lower than those in the control group (both P < 0.05). Correlation analysis showed that CSA measured by bedside ultrasound was positively correlated with GRV2, gastrointestinal dysfunction score, APACHE II score, and IAP (r values were 0.84, 0.78, 0.75, 0.72, all P < 0.01) and negatively correlated with PA and Alb (r values were -0.64 and -0.62, both P < 0.01). CONCLUSIONS: The Dachengqi decoction can significantly improve the clinical symptoms of septic patients with gastrointestinal dysfunction, reduce systemic inflammatory response, improve nutritional status, and shorten ICU hospital stay. Bedside ultrasound monitoring of CSA is a simple, accurate and effective means to evaluate gastrointestinal dysfunction, which is worthy of further clinical promotion.

RESUMO

Human milk (HM) has been associated with a lower risk of necrotizing enterocolitis (NEC). However, the association of precise HM proportion with the outcome of NEC remains unclear. A total of 77 cases and 154 matched controls were included in this study. The samples were divided into three groups based on the HM proportion of the total enteral intake before NEC onset: ≥70% (HHM), <70% (LHM), and 0% (NHM). The study cohort did not show a significant association between different HM proportions and NEC risk. The adjusted odds ratio (OR) for the highest versus the lowest intake was 0.599. In the prognosis of NEC, different HM proportions significantly affected weight gain, the timing of NEC onset, diagnosis time, hospitalization cost, and the severity of NEC (p < 0.05). Our findings support the beneficial effects of HM on reducing NEC in preterm infants, particularly when a greater proportion of HM of the total enteral intake is included in their feeding. Additionally, the study indicates that preterm infants fed with lower proportions of HM of the total enteral feeding are more prone to experiencing severe cases of NEC.

RESUMO

Background: Human milk (HM) is a proven optimal food for preterm infants. However, there is uncertainty regarding the effects of different proportions of HM of the total enteral intake on health outcomes in preterm infants. Therefore, we conducted a systematic review of studies examining the effects of different proportions of HM of the total enteral intake on health outcomes in preterm infants. Methods: We conducted a literature search in the Web of Science, PubMed, and Scopus databases. The methodological quality of the included articles and the certainty of evidence were assessed according to the Newcastle-Ottawa Scale and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool, respectively. Results: Twelve studies were included in the review. Among the clinical findings, the effect of different proportions of HM of the total enteral feeding on health outcomes in preterm infants was divided into six primary outcomes: physical growth, length of stay, morbidity of any disease, all-cause mortality, feeding-related outcomes, and other health outcomes. The studies presented a high risk of bias for most of the domains. The certainty of the evidence was considered low or very low. Conclusions: The findings reiterated that greater proportions of HM positively affect the health outcomes of preterm infants. Overall, when the HM accounts for at least 20% of the total enteral intake, it has an effect on health outcomes in preterm infants. If the proportion of HM reaches 50%, the incidence and severity of necrotizing enterocolitis, as well as the time to reach enteral feeds, will be reduced. Increasing the proportion of HM in enteral feeding should be considered a priority in the feeding strategy for preterm infants in clinical practice.

RESUMO

Atherosclerosis (AS) is a disease dangerous to human health and the main pathological cause of ischemic cardiovascular diseases. Although its pathogenesis is not fully understood, numerous basic and clinical studies have shown that AS is a chronic inflammatory disease existing in all stages of atherogenesis. It may be a common link or pathway in the pathogenesis of multiple atherogenic factors. Inflammation is associated with AS complications, such as plaque rupture and ischemic cerebral infarction. In addition to inflammation, apoptosis plays an important role in AS. Apoptosis is a type of programmed cell death, and different apoptotic cells have different or even opposite roles in the process of AS. Unlike linear RNA, circular RNA (circRNA) a covalently closed circular non-coding RNA, is stable and can sponge miRNA, which can affect the stages of AS by regulating downstream pathways. Ultimately, circRNAs play very important roles in AS by regulating inflammation, apoptosis, and some other mechanisms. The study of circular RNAs can provide new ideas for the prediction, prevention, and treatment of AS.

RESUMO

Bisphenol A (BPA) is an endocrine-disrupting chemical substance responsible for the composition of polycarbonate plastics and epoxy resins. Early life and pregnancy are important windows of susceptibility. This review aimed to conduct a systematic assessment of human studies to comprehensively describe the association between prenatal BPA exposure and neonatal health outcomes. Literature was searched in Cochrane Library, Embase, PubMed, Scopus, and Web of Science published before November 2022, and were selected according to clear inclusion and exclusion criteria. The Newcastle-Ottawa scale (NOS) and Grades of Recommendation, Assessment, Development, and Evaluation guidelines (GRADE) were followed to grade the methodological quality of studies and the certainty of the evidence respectively. As a result, a total of 22259 participants from 45 trials were included. And the potential associations of prenatal exposure to BPA and neonatal health outcomes were mainly shown in four aspects: gestational age/preterm birth, physical health at birth, the incidence of systemic abnormalities or diseases, and other health outcomes. Although the certainty of the evidence was low to very low, the methodological quality of the included studies was high. Prenatal BPA exposure tended to have negative effects on most of the health outcomes in neonates but showed inconsistent results on physical health at birth. This systematic review is the first to comprehensively synthesize the existing evidence on the association between prenatal BPA exposure and neonatal health outcomes. In the future, further studies are still needed to verify these effects and elucidate the underlying mechanisms.

RESUMO

In this study, a simple and effective coating method to improve printing quality and material utilization rate was proposed. The flow behavior of pico-liter scale ink droplets on the silk fabric surfaces which treated separately with Sodium alginate (SA), Hydroxyethyl cellulose (HEC) and Hydroxyethyl methyl cellulose (HEMC) was observed and measured. Indeed, based on the direct empirical results, the optimal pretreatment process on the fabrics, aiming to increase the ink utilization rate and further improve the surface printing clarity, has been obtained in the experiments. Studies on rheological property, surface activity, scanning electron microscope (SEM) and contact angle have shown that HEMC can form the densest and smoothest film on silk fabrics, where the most hydrophobic surface arises. X-ray photoelectron spectroscopy (XPS) results indicate that the surface of the fabric is covered with films of different properties formed by the treatment solution, and confirmed that the films formed by HEMC were more hydrophobic. The spreading motion of ink droplets revealed that although the hydrophobicity of HEC and HEMC effectively restrain the flow of ink droplet along the fiber, and the length and width of one-ink droplet deposition are minimum in HEMC treated fabric. Similarly, the findings on color performance suggest that HEMC has absolutely comparative advantage over HEC in improving the color effect of printing, with dye utilization rate of three different colors increasing by 68.7 %-80.0 %.

RESUMO

Early enteral feeding is vital for the physical health of preterm infants. However, there is uncertainty regarding the effects of early enteral feeding on health outcomes in preterm infants. Hence, we aimed to synthesise evidence from systematic reviews (SRs) to evaluate the effects of early enteral feeding on health outcomes in preterm infants. We conducted a literature search in PubMed, Web of Science, Scopus, and the Cochrane Database of Systematic Reviews. SRs selection followed clear inclusion and exclusion criteria. Two reviewers reached a consensus for the inclusion of SRs. The certainty of evidence and the quality of reviews using the GRADE and AMSTAR tools, respectively. We included nine SRs in this review. The effectiveness of early enteral feeding on health outcomes in preterm infants is mainly divided into six primary outcomes: increase the weight gain, reduce the incidence of feed intolerance, shorten the duration of full enteral feeding, reduce the length of hospital stay, reduce the incidence of necrotizing enterocolitis, and decrease the mortality risk. The overall quality of the included SRs was high, whereas most of the evidence was of low or very low certainty. Our results show the impact of early enteral feeding on health outcomes in preterm infants. Although the currently available data indicate that early enteral feeding may improve the health outcomes of preterm infants, additional clinical observation and investigation are required to evaluate the long-term health outcomes of preterm infants who receive early enteral feeding.

RESUMO

The recent advances in optic neuromorphic devices have led to a subsequent rise in use for construction of energy-efficient artificial-vision systems. The widespread use can be attributed to their ability to capture, store, and process visual information from the environment. The primary limitations of existing optic neuromorphic devices include nonlinear weight updates, cross-talk issues, and silicon process incompatibility. In this study, a highly linear, light-tunable, cross-talk-free, and silicon-compatible one-phototransistor-one-memristor (1PT1R) optic memristor is experimentally demonstrated for the implementation of an optic artificial neural network (OANN). For optic image recognition in the experiment, an OANN is constructed using a 16 × 3 1PT1R memristor array, and it is trained on an online platform. The model yields an accuracy of 99.3% after only ten training epochs. The 1PT1R memristor, which shows good performance, demonstrates its ability as an excellent hardware solution for highly efficient optic neuromorphic and edge computing.

RESUMO

Objective: Biliary innervation is considered important in regulating the function of bile ducts, whereas the role of innervation in the hepatobiliary system of patients with biliary atresia (BA) remains unknown. This current study aims to investigate the role of innervation in biliary remnants and analyze the relationship between the innervation and prognosis of BA after surgery. Methods: Eighty-seven patients with type III BA who underwent the Kasai procedure were consecutively enrolled from January 2017 to September 2020. Innervation and ductules in remnants were examined by pathologists. Liver function, onset of cholangitis, jaundice clearance, and survival with the native liver were recorded. Patients were followed up for 24 months. The relationship between innervation and prognosis was analyzed. Results: In total, 67 patients had bile drainage postoperatively, and 21 biliary remnants contained neuronal plexuses where there was no neuron but nerve fiber bundles. Acetylcholinesterase staining was positive in all plexuses. In patients with bile drainage, those with plexuses had improved postoperative liver function, significantly better jaundice clearance 3 or 6 months postoperatively (50.0% vs. 19.1%, or 90.0% vs. 63.8%, respectively), fewer episodes of early cholangitis (10.0% vs. 34.0%), and better survival (80.0% vs. 61.7%) compared to those without. In addition, a larger area of plexuses was associated with a larger area of ductules (R2 = 0.786, p = 0.000), less frequent (p = 0.000) and later cholangitis onset (p = 0.012), and better jaundice clearance (p = 0.063). Conclusions: Increased cholinergic innervation in biliary remnants may help reduce the onset of cholangitis and lead to better and earlier jaundice clearance. Thus, it improves the postoperative prognosis of patients with BA.

RESUMO

Ischemic stroke (IS) is a severe disease with a high disability, recurrence, and mortality rates. Autophagy, a highly conserved process that degrades damaged or aging organelles and excess cellular components to maintain homeostasis, is activated during IS. It influences the blood-brain barrier integrity and regulates apoptosis. Circular RNAs (circRNAs) are novel non-coding RNAs involved in IS-induced autophagy and participate in various pathological processes following IS. In addition, they play a role in autophagy regulation. This review summarizes current evidence on the roles of autophagy and circRNA in IS and the potential mechanisms by which circRNAs regulate autophagy to influence IS injury. This review serves as a basis for the clinical application of circRNAs as novel biomarkers and therapeutic targets in the future.

RESUMO

Background: To study the active ingredient and possible mechanism of Huisheng oral liquid in the treatment of lung cancer by network pharmacology. Methods: The active ingredient and drug targets of Huisheng oral liquid were screened using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and Traditional Chinese Medicine Integrated Database (TCMID), and lung cancer targets were screened using the Gene Expression Omnibus (GEO) database. The drug targets of the effective components of Huisheng oral liquid were matched with disease targets and the obtained intersecting targets were imported into the Search Tool for the Retrieval of Interaction Gene/Proteins (STRING) database to construct a protein-protein interaction (PPI) network. R software and the Kyoto Encyclopedia of Genes and Genomes (KEGG) database were used for Gene Ontology (GO) and KEGG enrichment analyses, and Cytoscape software was used to construct a Huisheng oral liquid component target-lung cancer target network. The function and pathway of the therapeutic target of Huisheng oral liquid for lung cancer were analyzed. Results: A total of 1,376 differentially expressed genes (DEGs) of lung cancer were obtained, and 185 potential effective components of Huisheng oral liquid in the treatment of lung cancer were obtained, including quercetin, luteolin, kaempferol, and baicalein. There were 36 intersecting targets between Huisheng oral liquid and lung cancer, and the key targets for lung cancer treatment were CDKN1A, CCNB1, MDM2, CDK1, ErbB2, E2F1, EGFR, etc. Huisheng oral liquid mainly regulates the p53 signaling pathway. Conclusions: The mechanism of Huisheng oral liquid in the treatment of lung cancer is mainly reflected in regulating tumor cell apoptosis, inhibiting angiogenesis, and improving immunity.

RESUMO

Background: Intracranial atherosclerotic stenosis (ICAS) is a common cause of first and recurrent ischemic stroke worldwide. Circular RNAs (circRNA)s have been recently suggested as candidate biomarkers in diagnosing and prognosis of ischemic stroke. A few circRNAs even serve as therapeutic targets that improves neurological function after ischemic stroke. However, the roles of circRNAs in ICAS caused ischemic stroke (ICAS-stroke) have not been fully understood. Therefore, in this study, we attempted to find some clues by investigating the different expression profiles of circRNAs between patients diagnosed with ICAS-stroke and normal control (NC)s. Methods: The OE Biotech Human ceRNA Microarray 4 × 180 K (47, 899 probes) screened circRNAs differentially expressed in peripheral blood in a discovery cohort (5 NCs versus five patients with ICAS-stroke). Afterwards, a validation cohort (31 NCs versus 48 patients with ICAS-stroke) was performed by quantitative polymerase chain reaction (qPCR). Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and CircRNA-microRNA-mRNA interaction network was performed to identify potential interactions with microRNAs and pathway-deregulated circRNAs. Results: There were 244 circRNAs differentially expressed in patients diagnosed with ICAS-stroke compared with NCs [fold change (FC) ≥ 2.0 and p-value<0.05]. Among the 244 circRNAs, 5 circRNAs (hsa_circ_0003574, hsa_circ_0010509, hsa_circ_0026628, hsa_circ_0074057, hsa_circ_0016993) were selected for following verification by qPCR. Only hsa_circRNA_0003574 was significantly upregulated in patients than in NCs. GO analysis indicated that predicted target genes involved various biological processes, cellular components, and molecular functions. KEGG analysis showed that many genes were enriched within the arginine and proline metabolism, pyrimidine metabolism, arginine and proline metabolism, lysosome, cytokine-cytokine receptor interaction, and RNA transport. The circRNA-miRNA-mRNA network analysis show the miRNAs that has_circ_0003574 likely interacts with. Conclusion: We observed that hsa_circRNA_0003574 is upregulated in patients with ICAS-stroke compared with NCs, indicating it may be a potential novel biomarker and therapeutic target for ICAS-stroke. In addition, we analyzed the laboratory results and found that homocysteine and glycosylated hemoglobin were elevated among ICAS-stroke patients. The relationship between hsa_circRNA_0003574 and these parameters requires further investigation.

RESUMO

As an important approach of distributed artificial intelligence, multi-agent system provides an efficient way to solve large-scale computational problems through high-parallelism processing with nonlinear interactions between the agents. However, the huge capacity and complex distribution of the individual agents make it difficult for efficient hardware construction. Here, we propose and demonstrate a multi-agent hardware system that deploys distributed Ag nanoclusters as physical agents and their electrochemical dissolution, growth and evolution dynamics under electric field for high-parallelism exploration of the solution space. The collaboration and competition between the Ag nanoclusters allow information to be effectively expressed and processed, which therefore replaces cumbrous exhaustive operations with self-organization of Ag physical network based on the positive feedback of information interaction, leading to significantly reduced computational complexity. The proposed multi-agent network can be scaled up with parallel and serial integration structures, and demonstrates efficient solution of graph and optimization problems. An artificial potential field with superimposed attractive/repulsive components and varied ion velocity is realized, showing gradient descent route planning with self-adaptive obstacle avoidance. This multi-agent network is expected to serve as a physics-empowered parallel computing hardware.

RESUMO

BACKGROUND: Preterm infants have higher nutrition needs than term infants. The effectiveness of various feeding supplementation was assessed by the improvement of health outcomes in single specific systematic reviews (SRs). The aim of this review was to comprehensively describe the effectiveness of feeding supplementation in promoting health outcomes of preterm infants. METHODS: A literature search was conducted in the PUBMED, EMBASE, Science Direct, Cochrane library, Web of Science, and Wiley online library. SRs selection followed clear inclusion and exclusion criteria. Pairs of reviewers independently applied the criteria to both titles/abstracts and full texts. Screening and data extraction were performed by using the advanced tables. The methodological quality of SRs and the quality of the evidence were carried out according to the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) tool and the Grades of Recommendation, Assessment, Development, and Evaluation guidelines (GRADE) respectively. A qualitative synthesis of evidence is presented. RESULTS: Seventeen SRs were included in the review. Fifteen kinds of feeding supplementation were reported in the SRs. In preterm infants, the effectiveness of feeding supplementation in addition to regular breast-feeding was mainly shown in six aspects: physical health, neurodevelopment, biochemical outcomes, other health outcomes, morbidity and all-cause mortality. And the effectiveness of the interventions on health outcomes in preterm infants was found by most systematic reviews. The methodological quality of all the included SRs was high, and most of the evidences was of low or very low quality. CONCLUSIONS: Our results will allow a better understanding of the feeding supplementation in preterm infants. Although the feeling supplements may improve the health outcomes of in preterm infants, the existing evidence is uncertain. Therefore, the clinical use of these supplements should be considered cautiously and more well-designed RCTs are still needed to further address the unsolved problems of the included SRs.

RESUMO

Dynamic physical systems such as reservoir computing (RC) architectures show a great prospect in temporal information processing, whereas hierarchical information processing capability is still lacking due to the absence of advanced multilayer reservoir elements. Here, a stackable reservoir system is constructed based on ferroelectric α-In2 Se3 devices with voltage input and output, which is realized by dynamic voltage division between a ferroelectric field-effect transistor and a planar device and therefore allows the reservoirs to cascade, enabling multilayer RC. Fast Fourier transformation analysis shows high-harmonic generation in the first layer as a result of inherent nonlinearity of the reservoir, and progressive low-pass filtering effect is realized where higher-frequency components are progressively filtered in deeper-layer RCs. Time-series prediction and waveform classification tasks are also demonstrated, serving as evidence for the memory capacity and computing capability of the deep reservoir architecture. This work can provide a promising pathway in exploiting emerging 2D materials and dynamics for advanced neuromorphic computing architectures.

RESUMO

The aim of this study was to explore the breastfeeding knowledge of nursing undergraduates and the influencing factors. Human milk (HM) is one of the most effective nutritional supplies to improve early development and physical health, but the current status of breastfeeding in China is still not optimal. The breastfeeding knowledge of perinatal women influences their feeding beliefs and behavior. Nursing undergraduates, as core professionals who will care for perinatal women and provide feeding guidance in the future, can significantly affect feeding behavior of mothers and their babies, so their knowledge of breastfeeding may have a potential impact on breastfeeding in China. However, studies on breastfeeding knowledge among nursing undergraduates in China are limited. A convenience sampling method was conducted in four medical universities in China, and eligible nursing undergraduates were selected. An online survey was collected from 5 July 2022 to 5 August 2022. Categorical data were reported as number and percentage, while continuous data were reported as mean ± SD. Multivariate linear regression was used to evaluate the association between influencing factors and breastfeeding knowledge. The overall mean score of the 460 returned questionnaires was 43.991 out of 100. The pass rate of the questionnaire was only 23.04%. Nursing undergraduates had a relatively better grasp of the benefits of breastfeeding and related advice (correct rates: 67.83%). Birthplace, only child or not, the course in obstetrics and gynecological nursing, the course in pediatrics nursing, and placements in maternity or neonatology units were relevant factors for breastfeeding knowledge (p < 0.05). Nursing undergraduates showed unsatisfactory breastfeeding knowledge. It is urgent to raise the knowledge level of breastfeeding among nursing undergraduates. Medical colleges should optimally structure a curriculum of breastfeeding knowledge. Furthermore, it is also necessary to improve the public's understanding of breastfeeding and the whole society's attention to breastfeeding in China.

RESUMO

Background: Sintilimab is an immune checkpoint inhibitor (ICI). It can induce immune-related Adverse Events (irAEs). Severe adverse skin reactions are rare, but the mortality rate is high. We report the first case of successful treatment of adverse skin reactions using traditional Chinese medicine (TCM). Case Description: Here we present the case of a 67-year-old male with advanced lung squamous carcinoma. After 8 cycles of chemotherapy, the patient's disease progressed and the treatment regimen was adjusted to sintilimab combined with albumin paclitaxel and cisplatin. Thirty-two days after this cycle, the patient reported a sporadic rash with pruritus on the face, front chest, and both upper limbs. The area of rash was 40%, and the adverse reaction was grade 3. The level of interleukin-related indicators was above normal. The patient's skin symptoms disappeared after treatment with hormones, TCM, and other drugs. The patient's adverse skin reaction was due to an immune-related toxicity caused by sintilimab, so treatment with sintilimab was suspended. The albumin-paclitaxel plus cisplatin regimen was continued to treat lung cancer. Conclusions: Although rare, case of fatal adverse reaction caused by sintilimab have been reported. We recommend early monitoring and recognition of symptoms. During management, high-dose hormones combined TCM may be helpful.
