- Abstract
Background: Endometrial cancer (EC) has a high latency, making prognosis difficult to predict. Cancer antigen 125 (CA125) is not specific as a tumour marker for EC; however, complete blood count (CBC) inflammatory markers are associated with prognosis in various malignancies. Thus, this study investigated the value of CBC inflammatory markers combined with CA125 levels in predicting the prognosis of patients with EC. Methods: In this study, 517 patients with EC were recruited between January 2015 and January 2022, and clinical characteristics, CBC inflammatory markers, and CA125 levels were assessed. Differences in each index at different EC stages and the correlation between the index and EC stage were analysed, and the influence of the index on EC prognosis was evaluated. Results: Platelet distribution width (PDW) levels were significantly lower in patients with advanced EC than in those with early EC, whereas the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and CA125 levels were significantly higher in patients with advanced EC (all P < 0.05). ROC curve and multivariate logistic regression analyses indicated that decreased PDW and increased CA125 levels were independent risk factors for EC staging progression. In addition, multivariate Cox regression analysis showed that the combination of low PDW and high CA125 (PDW + CA125 = 2) was an independent prognostic factor of survival in EC patients. Kaplan-Meier survival analysis indicated that patients with low PDW and high CA125 had worse overall survival. Conclusions: The PDW and CA125 score may be an independent prognostic factor for postoperative overall survival in patients with EC and a useful marker for predicting the prognosis of these patients. PLAIN LANGUAGE SUMMARY: Endometrial cancer (EC) has a high latency period, and the prognosis of EC is difficult to predict. The inflammatory response within the tumour microenvironment plays an important role in the occurrence and development of cancer. In our study, various inflammatory indicators in complete blood counts were comprehensively analysed, and cancer antigen 125 (CA125) was further used to predict the stage and prognosis of EC. The results showed that patients with low platelet distribution width (PDW) and high CA125 levels had poorer overall survival. The PDW and CA125 score may be used as a new independent prognostic indicator. [ABSTRACT FROM AUTHOR]

Light leakage was observed evidently when the panel was bent following the uniform circular arc curvature profile due to the residual stress. By simulation and experiment, we found that the curved panel stress and leakage can be significantly minimized when the uniform profile was modified into the un-uniform profile, which is meaningful to guide the curved LCDs design and manufacture.

- Abstract
Background: Group B streptococcus (GBS) causes neonatal invasive disease, mainly sepsis and meningitis. Understanding the clinical characteristics, laboratory tests, and antibiotic resistance patterns of GBS invasive infections provides reliable epidemiological data for preventing and treating GBS infections., Methods: Clinical characteristics and laboratory test results from 86 patients with neonatal invasive disease (45 cases of early-onset disease [EOD] and 41 cases of late-onset disease [LOD]) recruited from Fujian Maternity and Child Health Hospital between January 2012 and December 2021 were analyzed., Results: The number of neonates with invasive GBS infections declined for 10 years. Respiratory symptoms, the first clinical presentation in EOD, were predominant (71.1%), including groan, tachypnea, and cyanosis, whereas LOD more often presented with fever (78%). Pneumonia was the most common complication (57.0%). There were 35 patients (77.8%) with pneumonia and 18 patients (40.0%) with respiratory failure in the EOD cases, which were more than those in LOD cases. Neonates in the EOD cases were more prone to myocardial damage, cerebral injury, and metabolic acidosis than those in the LOD cases. The proportion of purulent meningitis (63.4%) and anemia (29.3%) in LOD was higher than those in EOD. White blood cell count of the EOD group was higher than that of the LOD group, whereas the proportion of patients with leukopenia was lower in the EOD group (24.4%) than in the LOD group (46.3%). All the GBS strains were susceptible to penicillin, ampicillin, linezolid, quinupristin, vancomycin, or tigecycline. Erythromycin and clindamycin resistance rates were 82.6% and 84.9%, respectively. A D-test revealed 48.6% iMLSB phenotype (inducible clindamycin resistant), and cMLSB phenotype (47.3%), L-phenotypes (2.7%), and M-phenotypes (1.4%) were also found., Conclusions: The number of cases of neonatal invasive GBS infections has decreased in recent years. Patients with invasive GBS-EOD infections have insidious onset symptoms and should be diagnosed early based on clinical symptoms and laboratory examination results. GBS strains are resistant to erythromycin and clindamycin, which is not suitable for prophylactic and empirical treatment in the neonatal population in this region.

- Abstract
Objective: To explore the risk of low-level blood group antibody-mediated hemolysis in ABO-incompatible newborns with negative three hemolysis tests, aiming to assist in the identification and management of neonatal jaundice., Methods: A retrospective case-control study was performed in 892 children with jaundice. The patients were divided into three groups: group I, ABO compatible, negative three hemolysis tests; group II, ABO incompatible, negative three hemolysis tests; and group III, ABO incompatible, positive three hemolysis tests. We analyzed the differences in clinical data, blood routine and biochemical laboratory results., Results: (1) Patients in group II had higher levels of mean corpuscular volume (MCV), standard deviation of red blood cell volume distribution width (RDW-SD), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), and bile acid (BA) than those in group I ( P < 0.05). However, there were no statistically significant differences in the MCV, ALT, ALP and BA levels between groups II and III ( P > 0.05). (2) Mean corpuscular hemoglobin concentration (MCHC) >359.5 g/L, cell volume distribution width (RDW-CV) >15.95%, and reticulocyte count (RET) >4.235% were identified as independent predictors of positive hemolysis test results ( P < 0.001). The combination of MCHC, RDW-CV, and RET% yielded an AUC of 0.841., Conclusion: Low-level blood group antibody-mediated hemolysis may occur in ABO-incompatible neonates even when three hemolysis tests are negative. Changes in liver function parameters must be monitored. The combination of MCHC, RDW-CV, and RET% can be used to improve the detection rate of HDN., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Lin, Luo, Liu, Lin, Que and Zhong.)

- Abstract
Background: Streptococcus agalactiae (GBS) and Escherichia coli (E. coli) are the main pathogenic bacteria in neonatal sepsis. Therefore, the clinical characteristics, nonspecific indicators, and drug susceptibilities of these two bacteria were studied., Methods: In total, 81 and 80 children with sepsis caused by GBS and E. coli infection, respectively, admitted to the neonatal department of our hospital between May 2012 and July 2023, were selected, and the clinical characteris-tics of the two groups were analyzed. Nonspecific indicators and drug sensitivity test results were analyzed retrospectively., Results: Birth weight, tachypnea, groan, tachycardia or bradycardia, and the incidence of complications, such as pneumonia, respiratory failure, and purulent meningitis, were higher in the GBS group than in the E. coli group. The children were born prematurely, and the mother had a premature rupture of membranes. The incidence of jaundice, abdominal distension, atypical clinical manifestations, and complications of necrotizing enterocolitis was lower than of the E. coli group, and the differences were statistically significant (p < 0.05). The WBC, NE#, NE#/LY#, hs-CRP, and PCT of the GBS group were higher than those of the E. coli group, whereas the MPV, D-D, and FDP levels were lower than those in the E. coli group. The differences were all statistically significant (p < 0.05). The 81-bead GBS had high resistance rates against tetracycline (95%), erythromycin (48.8%), and clindamycin (40%), and no strains resistant to vancomycin, linezolid, penicillin, or ampicillin appeared, whereas 80 strains of E. coli were more resistant to penicillin and third-generation cephalosporins, with the higher resistance rates to ampicillin (68.30%), trimethoprim/sulfamethoxazole (53.6%), and ciprofloxacin (42.90%). Resistance rates to carbapenems and aminoglycosides were extremely low., Conclusions: Both GBS and E. coli neonatal sepsis have specific clinical characteristics, especially in terms of clinical manifestations, complications, non-specific indicators, and drug resistance. Early identification is important for clinical diagnosis and treatment.
