ABSTRACT

Introducción COVID- 19, es una enfermedad que ha cobrado la vida de muchas personas. Sin embargo, las alteraciones en los perfiles de labora-torio en la ciudad de Tacna, no han sido establecidas de manera precisa en asociacion a su gravedad para apoyo en el diagnostico y tratamiento. Objetivo Determinar los biomarcadores que esten relacionados al grado de severidad de los pacientes COVID- 19 atendidos en el hospital de la seguridad social, en Tacna durante 2020. Métodos Estudio observacional, transversal y analitico. Conformado por 308 pacientes con COVID- 19 del hospital de la seguridad social de la ciudad de Tacna, Peru, durante el golpe de la "primera ola" (de julio a agosto de 2020). Se recolectaron resultados de marcadores inmunologicos, hematologicos, gases arteriales, hemostasia y bioquimicos. Los pacientes se categorizaron en leves, moderados y severos, basandonos en el criterio medico ­ clinico de la historia clinica. Las correlaciones y fuerza de correlacion fueron realizadas segun coeficiente Rho de Spearman. El rendimiento de los biomarcadores asociado a la gravedad, se realizo con curva Receiver Operating Characteristic. Resultados En marcadores hematologicos existe correlacion positiva con recuento de monocitos (coeficiente de correlacion: 0,841; area bajo la curva 97,0%; p < 0,05) y correlacion negativa con recuento de linfocitos (coeficiente de correlacion: -0,622; area bajo la curva 8.27%; p < 0,05). En marcadores bioquimicos, gases arteriales y hemostasia, no se hallaron correlaciones significativas. En marcadores in-munologicos, encontramos correlacion positiva con ferritina (coeficiente de correlacion: 0,805; area bajo la curva 94,0%; p < 0,05), y proteina C reactiva (coeficiente de correlacion: 0,587; area bajo la curva 87,4%; p < 0,05). Conclusiones Los biomarcadores que pueden considerarse como parametros asociados a la gravedad de COVID- 19, son el recuento sanguineo absoluto de monocitos y la concentracion serica de ferritina.


Introduction COVID- 19 is a disease that has claimed the lives of many people. However, alterations in labo-ratory profiles in the city of Tacna have not been accurately established in association with its severity to support diagnosis and treatment. Objective To determine biomarkers related to the severity of COVID- 19 in patients treated at the social security hospital in Tacna during 2020. Methods We performed an observational, cross- sectional, and analytical study that included 308 patients with COVID- 19 from the social security hospital in Tacna, Peru, during the "first wave" of the pandemic (from July to August 2020). Immunological, hematological, arterial gas, hemostasis, and biochemical markers were collected. Patients were categorized into mild, moderate, and severe based on the clinical criteria found on clinical records. Correlation strength was per-formed according to Spearman's Rho coefficient. The performance of the biomarkers associat-ed with severity was analyzed with the Receiver Operating Characteristic curve. Results Regarding hematological markers there was a positive correlation with monocyte count (correla-tion coefficient: 0.841; area under the curve 97.0%; p < 0.05) and a negative correlation with lymphocyte count (correlation coefficient: -0.622; area under the curve 82.7%; p < 0.05). Regarding biochemical markers, arterial gases and hemostasis, no significant correlations were found. In immunological markers, we found positive correlation with ferritin (correlation coef-ficient: 0.805; area under the curve 94.0%; p < 0.05), and C- reactive protein (correlation coeffi-cient: 0.587; area under the curve 87.4%; p < 0.05). Conclusions The biomarkers that can be considered as parameters associated with the severity of COVID- 19 are the absolute blood count of monocytes and serum ferritin concentration.

ABSTRACT

Background: Organic colonic manifestation may be difficult to be differentiated from functional one. Inflammatory bowel disease (IBD) is a common chronic inflammatory and destructive disease of the bowel wall. Chronic inflammation is associated with ulcerations, strictures, perforations, and it is a risk factor for dysplasia and cancer. To reduce these long-standing complications, IBD patients are in a continuous need for early diagnosis1. Markers, such as erythrocyte sedimentation rate (ESR), and c-reactive protein (CRP), fecal calprotectin (FC) have been widely used as noninvasive parameters for IBD monitoring. We aimed, in this current study, to evaluate the value of fecal calprotectin and other noninvasive biomarkers in predicting abnormal histologic findings in patients undergoing colonoscopy.in addition to determine the cutoff value which predict IBD2. Methods: The present prospective study included 160 patients with complaint of colicky abdominal pain with frequent diarrhea associated with mucous and infrequent bleeding per rectum for more than 6 months. They presented partial improvement with medication and recurrence once stopping the treatment These patients had been recently diagnosed with IBD at many primary healthcare centers covering the areas of the Kafrelsheikh and Zagazik governorate in the North of Egyptian Nile delta. After complete history, clinical examination, and laboratory investigation, they were referred to the IBD clinic at Kafrelsheikh University Hospital for assessment and ileocolonoscopy with biopsies. Results: There was a wide spectrum of age of the studied patients, with mean age 40.12±7.88 (minimum 18 and maximum 56 years). Regarding gender, males represented 87.5% of the studied patients. Forty percent of the patients with colonic manifestation were smokers, 57% preferred a spicy diet, and the majority had low educational level (77.5%). Forty percent had obvious blood in stool, 55% had occult blood, and raised ESR CRP occurred in 32.5% and 50%, respectively. Fecal calprotectin cutoff was>159, with sensitivity 92.8% and specificity 97.5%. Conclusions: Biomarkers (FC, ESR, CRP) can be used as noninvasive parameters for the early diagnosis and prediction of organic colonic disease. Fecal calprotectin in the IBD group revealed significant area under the curve (AUC) values and cutoff> 159, with sensitivity 92.8% and specificity 97.5%. (AU)

ABSTRACT

The aim of the study was to evaluate the effect of the volume of participation in exercise programs offered in Primary Health Care (PHC), for 24 weeks on blood biochemical parameters of adult women. Three Basic Health Units in Rio Claro City (São Paulo) were selected and 2 exercise inter-ventions were implemented with different volumes (3 weekly sessions, 90 minutes each; 2 weekly sessions, 60 minutes each). In total, 53 participants remained until the end of the interventions. Regardless of their number of absences, they were divided into 4 groups, according to the volume of participation (calculated individually according to the duration of sessions and the number of classes held), forming groups according to quartiles: Low Volume Group (LVG; 57.62 ± 9.97 years-old), Low Medium Volume Group (LMVG; 56.31 ± 12.18 years-old), High Medium Volume Group (HMVG; 53.00 ± 10.25 years-old), and High-Volume Group (HVG; 59.69 ± 7.66 years-old). Blood biochemical parameters were dosed using the ELISA method. The Generalized Estimation Equa-tion Model was used to compare the biochemical parameters (time, group, and interaction; p ≤ 0.05). The analysis showed significant and positive time effect for low-density lipoproteins (LDL) and glycemia in all groups and for total cholesterol (TC) in LVG, LMVG and HMVG; a significant group effect for HVG on TC (higher levels compared to all other groups) and LDL (higher levels compared to LVG and LMVG). It is concluded that the physical exercise programs offered in the PHC contributed to a significant reduction in LDL and blood glucose levels, regardless of the vol-ume of participation of individuals in the programs


O objetivo do presente estudo foi avaliar o efeito do volume de participação em programas de exercícios, ofer-tados na Atenção Primária à Saúde (APS), durante 24 semanas, nos parâmetros bioquímicos sanguíneos de mulheres adultas. Foram selecionadas 03 Unidades Básicas de Saúde de Rio Claro-São Paulo e implementa-das 2 intervenções de exercícios com diferentes volumes (3 sessões/semana, 90 minutos cada; 2 sessões/semana, 60 minutos cada). No total, 53 participantes se mantiveram até o final das intervenções, independentemente do número de faltas foram divididos em 4 grupos, de acordo com o volume de participação (calculado con-forme a duração das sessões e a quantidade de aulas realizadas de forma individual), formando os grupos segundo os quartis: Grupo Baixo Volume (GBV; 57,62 ± 9,97 anos), Grupo Baixo Médio Volume (GBMV; 56,31 ± 12,18 anos), Grupo Médio Alto Volume (GMAV; 53,00 ± 10,25 anos) e Grupo Alto Volume (GAV; 59,69 ± 7,66 anos). Os parâmetros bioquímicos sanguíneos foram dosados pelo método ELISA. Foi utilizado o Modelo de Equações de Estimações Generalizadas para a comparação dos parâmetros bioquímicos (tempo, grupo e interação; p ≤ 0,05). A análise evidenciou efeito significativo favorável do tempo para lipoproteínas de baixa densidade (LDL) e glicemia em todos os grupos e para colesterol total (CT) no GVB, GBMV e GMAV; e efeito significativo do grupo para GAV no CT (maiores níveis comparado a todos os grupos) e LDL (maiores níveis comparados ao GBV e GBMV ). Conclui-se que o programa de exercício físico ofertado na APS contribuiu para a redução significativa dos níveis de LDL e glicemia, independentemente do volume de participação dos indivíduos nos programas

ABSTRACT

SUMMARY OBJECTIVES: This study aimed to investigate the ability of the biomarkers to predict the surgery treatment and mortality in patients above 18 years of age who were hospitalized with the diagnosis of bowel obstruction from the emergency department. METHODS: This is a 2-year retrospective study. The patients' demographic data, laboratory parameters on admission to emergency department, treatment modalities, and the length of hospital stay were recorded. Patients were divided into two groups: conservative and surgical treatment. Statistical analysis was performed to investigate the value of biomarkers in predicting mortality and the need for surgery. Data were analyzed using IBM SPSS version 22. RESULTS: A total of 179 patients were included in this study. Of these, 105 (58.7%) patients were treated conservative and 74 (41.3%) were treated operatively. The elevated procalcitonin (PCT) level, C-reactive protein, blood urea nitrogen-to-albumin ratio, and lactate-to-albumin ratio were significantly correlated with surgical treatment, length of hospital stay, and mortality. procalcitonin threshold value of 0.13 ng/mL was able to predict the need for surgical treatment, with a sensitivity of 79% and a specificity of 70.3%. Procalcitonin threshold value of 0.65 ng/mL was able to predict the mortality rate of the patients, with a sensitivity of 92.9% and a specificity of 78.1%. CONCLUSIONS: Biomarkers, especially procalcitonin, may be useful in bowel obstruction treatment management and may predict mortality.

ABSTRACT

SUMMARY OBJECTIVE: The aim of this study was to evaluate and compare C-reactive protein and C-reactive protein-to-albumin ratio performances in predicting mortality of geriatric patients who visited the emergency department. METHODS: The data of patients with COVID-19 and aged 65 years and above, who visited emergency department during the study period, were retrospectively analyzed. The data were obtained from an electronic-based hospital information system. The area under the receiver operating characteristic curve and the area under the curve were used to assess each cutoff value discriminatory for predicting mortality. RESULTS: The mean age of the population included in this study was 76 (71-82) years, while 52.7% were males. The sensitivity, specificity, and area under the curve values for C-reactive protein in terms of mortality were calculated as 71.01, 52.34, and 0.635%, respectively, while the sensitivity, specificity, and area under the curve values for C-reactive protein-to-albumin ratio were calculated as 75.74, 47.66, and 0.645%, respectively (p<0.001). In the pairwise comparison for the receiver operating characteristic curves of C-reactive protein and C-reactive protein-to-albumin ratio, no statistically significant difference was found. CONCLUSIONS: Geriatric patients are the "most vulnerable" patient group against the COVID-19. In this study, both C-reactive protein and C-reactive protein-to-albumin ratio were found to be successful in predicting mortality for geriatric COVID-19 patients.

ABSTRACT

OBJECTIVE@#To study the cytokine patterns in patients with rheumatoid arthritis (RA) and healthy individuals and identify candidate serum biomarkers for clinical diagnosis of RA.@*METHODS@#This study was conducted among 59 patients diagnosed with RA in our hospital from 2015 to 2019 with 46 age- and gender-matched healthy subjects who received regular physical examinations in our hospital as the control group. Serological autoimmune profiles of 5 RA patients and 5 healthy control subjects were obtained from human cytokine microarrays. We selected 4 differentially expressed cytokines (LIMPII, ROBO3, Periostin and IGFBP-4) and 2 soluble cytokine receptors of interest (2B4 and Tie-2) and examined their serum levels using enzyme-linked immunosorbent assay in 54 RA patients and 41 healthy control subjects. Spearman correlation test was performed to assess the correlation of serum cytokine and soluble receptor expression levels with the clinical features including rheumatoid factor (RF), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), disease activity score (DAS28) and health assessment questionnaire (HAQ). Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic capability of these cytokines.@*RESULTS@#We identified 6 dysregulated cytokines and soluble receptors (2B4, LIMPII, Tie-2, ROBO3, periostin and IGFBP-4) in RA patients (P < 0.01). The serum levels of LIMPII, ROBO3 and periostin were significantly correlated with the disease activity indicators including RF (P < 0.001), CRP (P < 0.001), DAS28 (P < 0.001) and HAQ (P < 0.001) in RA patients. Among the 6 candidate cytokines, 2B4 showed the largest area under the curve (AUC) of 0.861 for RA diagnosis (P < 0.001), followed then by LIMPII, ROBO3, periostin, Tie-2 and IGFBP-4.@*CONCLUSION@#Serum levels of LIMPII, ROBO3 and periostin can be indicative of the disease activity of RA, and serum 2B4, LIMPII, periostin, ROBO3, IGFBP-4 and Tie-2 levels may serve as biomarkers for the diagnosis of RA.

ABSTRACT

OBJECTIVE@#To explore the association between postoperative C-reactive protein (CRP) levels and the occurrence of postoperative atrial fibrillation in patients undergoing cardiopulmonary bypass surgery.@*METHODS@#We retrospectively analyzed the data of 550 patients undergoing cardiopulmonary bypass surgery in our hospital from September, 2018 to May, 2021, and after screening against the exclusion criteria, 363 patients were selected for further analysis. Univariate analysis was used to analyze the correlation of age and early postoperative CRP level with the occurrence of postoperative atrial fibrillation, and Chi-square test was used to explore the correlation of gender, disease type, and comorbidity with postoperative atrial fibrillation followed by multivariate analysis of the data using a binary logistic regression model.@*RESULTS@#The 363 patients enrolled in this study included 247 with valvular disease, 42 with aortic dissection, 37 with coronary heart disease, and 37 with congenital heart disease, with a median postoperative CRP level of 88.65 mg/L and a median age of 57 years (range 5-77 years). Postoperative atrial fibrillation occurred in 101 (27.82%) of the patients, who were subsequently divided into atrial fibrillation group and sinus group. Univariate and multivariate correlation analyses showed that early postoperative elevation of CRP level was an important factor contributing to the occurrence of postoperative atrial fibrillation.@*CONCLUSION@#Early postoperative elevation of CRP level is associated with the occurrence of atrial fibrillation following cardiopulmonary bypass surgery.

ABSTRACT

OBJECTIVES@#Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation and joint destruction. Both inflammatory response and oxidative stress contribute to the pathogenesis of RA. Oxidative damage can induce and aggravate the imbalance of immune inflammation and promote cell and tissue damage. In this study, the expression of long non-coding RNA (lncRNA) LINC00638 in peripheral blood of patients with RA damp-heat arthralgia syndrome was observed, and the correlation between LINC00638 and disease activity, immune inflammation and oxidative stress indicator was investigated. Subsequently, the mechanisms for LINC00638 in regulating the inflammatory response and oxidative stress in RA fibroblast-like synoviocyte (FLS) under the condition of overexpression and interference were further explored.@*METHODS@#In this study, 48 RA patients with damp-heat arthralgia syndrome and 27 normal healthy subjects, who came from Department of Rheumatology, First Affiliated Hospital of Anhui University of Chinese Medicine, were included; and they were divided into a RA group and a control group. The expression of LINC00638 in peripheral blood mononuclear cells (PBMC) from the subjects was detected by real-time PCR. Enzyme linked immunosorbent assay (ELISA) was used to detect serum interleukin (IL)-10, IL-17, tumor necrosis factor-α (TNF-α), malondialdehyde (MDA), heme oxygenase 1 (HO-1) and superoxide dismutase 2 (SOD2) expression. Spearman method was used to study the relationship between LINC00638 and erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptide antibody (anti-CCP), and to observe the relation between LINC00638 and the Disease Activity Score of 28 Joint (DAS28), Quantitative Score of Damp Heat Syndrome, Visual Analogue Scale (VAS), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS). RA-FLS was induced by RA-PBMC, and the RA in vitro cell experimental model was established. LINC00638 overexpression plasmid and small interfering RNA (siRNA) were constructed and transfected into RA-FLS. The cell experiments were divided into 4 groups: a pcDNA3. 1- control group, a pcDNA3.1-LINC00638 group, a siRNA-control group, and a siRNA-LINC00638 group. The transfection efficiency of overexpression plasmid and siRNA was detected by real-time PCR, the expression of TNF-α and IL-10 was detected by ELISA, and the expression of antioxidant proteins HO-1 and SOD2 was detected by immunofluorescence.@*RESULTS@#Compared with the control group, the expression of LINC00638 in the RA group was lower (P<0.01). The area under the curve (AUC) of the receiver operating characteristic (ROC) curve of LINC00638 was 0.9271. The DAS28 in RA group was 5.70 (5.40-6.50), the Quantitative Score of Damp-heat Syndrome was 20.0 (17.0-23.0), and the VAS score was 7.0 (6.3-8.0). Compared with the control group, the ESR, CRP, RF, anti-CCP, SAS and SDS scores in the RA group were significantly increased (all P<0.01). Spearman correlation analysis showed that: LINC00638 was negatively correlated with ESR (r=-0.532, P<0.01), CRP (r=-0.367, P<0.05), TNF-α (r=-0.375, P<0.01), MDA (r= -0.295, P<0.05), DAS28 (r=-0.450, P<0.01), and which was positively correlated with SOD2 (r=0.370, P<0.05). After the induction of RA-FLS, the expression level of LINC00638 was significantly decreased (P<0.01), indicating that the stimulation of PBMC could effectively reduce the expression of LINC00638 in RA-FLS, so the experimental model of RA-FLS-induced by PBMC was utilized. Compared with the pcDNA3.1-control group, the expressions of LINC00638, IL-10, SOD2, and HO-1 in the pcDNA3.1-LINC00638 group were significantly increased (all P<0.01), and the expression of TNF-α was decreased (P<0.01). Compared with siRNA-control group, LINC00638, IL-10, SOD2 and HO-1 in the siRNA-LINC00638 group were significantly decreased (all P<0.01), and TNF-α was significantly increased (P<0.01).@*CONCLUSIONS@#LINC00638 is down-regulated in the peripheral blood of RA patients with damp-heat arthralgia syndrome, which is correlated with disease activity, immune inflammation and oxidative stress. Overexpression of LINC00638 can down-regulate pro-inflammatory factors, up-regulate anti-inflammatory factors, and increase antioxidant enzyme activity, thereby improving inflammation and oxidative stress in RA. LINC00638 is the differential lncRNA obtained by the research group's previous high-throughput sequencing of the whole transcriptome of peripheral blood PBMCs in RA patients and validation of clinical samples. In order to deepen the molecular biology research of this gene, the microRNA and mRNA targeted by LINC00638 can be further studied from the perspective of competing endogenous RNAs.

ABSTRACT

OBJECTIVE@#To investigate the clinical characteristics and risk factor analysis of necrotizing pneumonia in children.@*METHODS@#A retrospective study was used to analyze the case data of 218 children with severe pneumonia hospitalized in the Department of Respiratory Medicine, Children's Hospital of Capital Institute of Pediatrics from January 2016 to January 2020, and they were divided into 96 cases in the necrotizing pneumonia group (NP group) and 122 cases in the non-necrotizing pneumonia group (NNP group) according to whether necrosis of the lung occurred. The differences in clinical characteristics (malnutrition, fever duration, hospitalization time, imaging performance, treatment and regression follow-up), laboratory tests [leukocytes, neutrophil ratio, platelet (PLT), C-reactive protein (CRP), procalcitonin (PCT), D-dimer, and lactate dehydrogenase (LDH)] and bronchoscopic performance between the two groups were compared, and Logistic regression analysis of clinical risk factors associated with necrotizing pneumonia was performed to further determine the maximum diagnostic value of each index by subject operating characteristic curve (ROC). The critical value of each index was further determined by the ROC.@*RESULTS@#The differences in age, gender, pathogenic classification, and bronchoscopic presentation between the two groups of children were not statistically significant (P>0.05); whereas the imaging uptake time of the children in the NP group was higher than that in the NNP group (P < 0.05). The differences in malnutrition, fever duration, length of stay, white blood cell count, neutrophil ratio, CRP, PCT, and D-dimer were statistically significant between the two groups (P < 0.05). The imaging uptake time was lower in children under 6 years of age than in those over 6 years of age, and the imaging uptake time for bronchoalveolar lavage within 10 d of disease duration was lower than that for those over 10 d; the imaging uptake time was significantly longer in the mixed infection group than that in the single pathogen infection group. Logistic regression analysis of the two groups revealed that the duration of fever, hospital stay, CRP, PCT, and D-dimer were risk factors for secondary pulmonary necrosis (P < 0.001, P < 0.001, P < 0.001, P=0.013, P=0.001, respectively). The ROC curves for fever duration, CRP, PCT, and D-dimer were plotted and found to have diagnostic value for predicting the occurrence of pulmonary necrosis when fever duration >11.5 d, CRP >48.35 mg/L, and D-dimer > 4.25 mg/L [area under ROC curve (AUC)=0.909, 0.836, and 0.747, all P < 0.001].@*CONCLUSION@#Children with necrotizing pneumonia have a longer heat course and hospital stay, and the imaging uptake time of mixed pathogenic infections is significantly longer than that of single pathogenic infections. Children with necrotizing pneumonia under 6 years of age have more advantageous efficacy of electronic bronchoscopic alveolar lavage within 10 d of disease duration compared with children in the group over 6 years of age and children in the group with disease duration >10 d. Inflammatory indexes CRP, PCT, and D-dimer are significantly higher. The heat course, CRP, PCT, and D-dimer are risk factors for secondary lung necrosis in severe pneumonia. Heat course >11.5 d, CRP >48.35 mg/L, and D-dimer >4.25 mg/L have high predictive value for the diagnosis of necrotizing pneumonia.

ABSTRACT

OBJECTIVE@#To investigate the association between serum high sensitivity C-reaction protein (hsCRP) in early pregnancy and gestational diabetes mellitus (GDM) among twin pregnant women, and to explore the effects of the pre-pregnant body mass index (BMI) and gestational weight gain (GWG) status on such association.@*METHODS@#Twin pregnant women with pre-pregnant BMI greater than or equal to 18.5 kg/m2 were recruited at Department of Obstetrics and Gynecology of Peking University Third Hospital from March 2017 to December 2020. Serum samples collected in early pregnancy were analyzed for hsCRP using particle-enhanced immunoturbidimetric method. In the following visits, the information about GWG and GDM were prospectively collected in every trimester. The association effect between hsCRP tertiles and GDM were estimated using Logistic regression, and further converted into risk ratio (RR). Cochran-Mantel-Haenszel test and mediation analysis were used to explore the effects of BMI and GWG status on the association.@*RESULTS@#Among the included 570 twin pregnant women, 31.6% deve-loped GDM, 26.1% were pre-pregnant overweight or obesity, and 49.5% with GWG out of referenced range. After adjustment for confounding factors, risk of developing GDM in twin gestations with the middle tertile and highest tertile of serum hsCRP in early pregnancy were 1.42 fold (95%CI: 1.02-1.89) and 1.54 fold (95%CI: 1.12-2.02), respectively, compared with the lowest tertile of serum hsCRP, and there existed significantly linear trend (P=0.022). Findings from mediation analysis illustrated that pre-pregnant BMI had partial mediating effect on the association, and BMI accounted for 23.84% (P < 0.001) of the increasing GDM risks with elevated hsCRP. Joint analysis with hsCRP and GWG found that those who were with GWG out of referenced range accompanied with the higher hsCRP tertiles (>1.21 mg/L) had significantly 2.31 fold increased risk according to those who were with GWG in the referenced range accompanied with the lowest hsCRP tertile (≤1.21 mg/L, P < 0.01).@*CONCLUSION@#Elevated hsCRP in early pregnancy significantly increased GDM risk among twin pregnant women. The hsCRP-GDM association was dependent on GWG status, and pre-pregnant BMI had partial mediating effect on such association. It is suggested that twin pregnant women should consider systemic inflammation and gestational weight at the same time to reduce GDM risk.

ABSTRACT

OBJECTIVES@#Percutaneous coronary intervention (PCI) is one of the important methods for the treatment of coronary artery disease (CAD). In-sent restenosis (ISR) after PCI for patients suffered from CAD is considered to be an essential factor affecting long-term outcomes and prognosis of this disease. This study aims to investigate the correlation between plasma Quaking (QKI) and cyclooxygenase-2 (COX-2) levels and ISR in patients with CAD.@*METHODS@#A total of 218 consecutive CAD patients who underwent coronary angiography and coronary arterial stenting from September 2019 to September 2020 in the Department of Cardiology of Xiangya Hospital of Central South University were enrolled in this study, and 35 matched individuals from the physical examination center were served as a control group. After admission, clinical data of these 2 groups were collected. Plasma QKI and COX-2 levels were measured by enzyme linked immunosorbent assay (ELISA). Follow-up angiography was performed 12 months after PCI. CAD patients were divided into a NISR group (n=160) and an ISR group (n=58) according to the occurrence of ISR based on the coronary angiography. The clinical data, coronary angiography, and stent features between the NISR group and the ISR group were compared, and multivariate logistic regression was used to explore the factors influencing ISR. The occurrence of major adverse cardiovascular events (MACE) 1 year after operation was recorded. Fifty-eight patients with ISR were divided into an MACE group (n=24) and a non-MACE group (n=34), classified according to the occurrence of MACE, and the plasma levels of QKI and COX-2 were compared between the 2 groups. Receiver operating characteristic (ROC) curves were utilized to analyze the diagnostic value of plamsa levels of QKI and COX-2 for ISR and MACE occurrences in patients after PCI.@*RESULTS@#Compared with control group, plasma levels of QKI and COX-2 in the CAD group decreased significantly (all P<0.001). Compared with the NISR group, the plasma levels of QKI and COX-2 also decreased obviously in the ISR group (all P<0.001), while the levels of high sensitivity C-reactive protein (hs-CRP) and glycosylated hemoglobin (HbAlc) significantly increased (all P<0.001). The level of COX-2 was negatively correlated with hs-CRP (r=-0.385, P=0.003). Multivariate logistic regression analysis showed that high level of plasma QKI and COX-2 were protective factors for in-stent restenosis after PCI, while hs-CRP was a risk factor. ROC curve analysis showed that the sensitivity and specificity of plasma QKI for evaluating the predictive value of ISR were 77.5% and 66.5%, respectively, and the sensitivity and specificity of plasma COX-2 for evaluating the predictive value of ISR were 80.0% and 70.7%, respectively. The sensitivity and specificity of plasma QKI combined with COX-2 for evaluating the predictive value of ISR were 81.3% and 74.1%, respectively. The sensitivity and specificity of plasma QKI for evaluating the prognosis of ISR were 75.0% and 64.7%, respectively. The sensitivity and specificity of plasma COX-2 for evaluating the prognosis of ISR were 75.0% and 70.6%, respectively. The sensitivity and specificity of plasma QKI combined with COX-2 for prognostic evaluation of ISR were 81.7% and 79.4%, respectively. The sensitivity and specificity of plasma COX-2 combined with QKI for evaluating ISR and MACE occurrences in patients after PCI were better than those of COX-2 or QKI alone (P<0.001).@*CONCLUSIONS@#High level of plasma QKI and COX-2 might be a protective factor for ISR, which can also predict ISR patient's prognosis.

ABSTRACT

OBJECTIVES@#To study the value of autotaxin (an autocrine motility factor) level in serum and bronchoalveolar lavage fluid (BALF) in predicting refractory Mycoplasma pneumoniae pneumonia (RMPP) in children and its correlation with interleukin-6 (IL-6), interleukin-8 (IL-8), and C-reactive protein (CRP).@*METHODS@#A retrospective analysis was performed on 238 children with Mycoplasma pneumoniae pneumonia who were admitted from January 2019 to December 2021. According to disease severity, they were divided into two groups: RMPP (n=82) and general Mycoplasma pneumoniae pneumonia (GMPP; n=156). The two groups were compared in terms of the levels of autotaxin, IL-6, IL-8, and CRP in serum and BALF to study the value of autotaxin level in serum and BALF in predicting RMPP in children, as well as the correlation of autotaxin level with IL-6, IL-8, and CRP in children with RMPP.@*RESULTS@#Compared with the GMPP group, the RMPP group had significantly higher levels of autotaxin, IL-6, IL-8, and CRP in serum and BALF (P<0.05). For the children with RMPP, the levels of autotaxin, IL-6, IL-8, and CRP in serum and BALF in the acute stage were significantly higher than those in the convalescent stage (P<0.05). The receiver operating characteristic (ROC) curve showed that the level of autotaxin in serum and BALF had a good value in predicting RMPP in children, with an area under the curve of 0.874 (95%CI: 0.816-0.935) and 0.862 (95%CI: 0.802-0.924), respectively. The correlation analysis showed that the level of autotaxin in serum and BALF was positively correlated with IL-6, IL-8, and CRP levels (P<0.001).@*CONCLUSIONS@#The level of autotaxin in serum and BALF increases and is correlated with the degree of disease recovery and inflammatory cytokines in children with RMPP. Autotaxin can be used as a predictive indicator for RMPP in children.

ABSTRACT

OBJECTIVES@#To summarize the clinical features of liver damage in children in the acute stage of Kawasaki disease (KD), and to investigate the clinical value of liver damage in predicting coronary artery lesion and no response to intravenous immunoglobulin (IVIG) in children with KD.@*METHODS@#The medical data were collected from 925 children who were diagnosed with KD for the first time in Beijing Children's Hospital from January 1, 2016 to December 31, 2017. According to the presence or absence of abnormal alanine aminotransferase (ALT) level on admission, the children were divided into a liver damage group (n=284) and a non-liver damage group (n=641). A logistic regression analysis was used to investigate the clinical value of the indicators including liver damage in predicting coronary artery lesion and no response to IVIG in children with KD.@*RESULTS@#Compared with the non-liver damage group, the liver damage group had a significantly earlier admission time and significantly higher serum levels of inflammatory indicators (P<0.05). The liver damage group had a significantly higher incidence rate of coronary artery lesion on admission than the non-liver damage group (P=0.034). After initial IVIG therapy, the liver damage group had a significantly higher proportion of children with no response to IVIG than the non-liver damage group (P<0.001). In children with KD, coronary artery lesion was associated with the reduction in the hemoglobin level and the increases in platelet count, C-reactive protein, and ALT (P<0.05), and no response to IVIG was associated with limb changes, the reduction in the hemoglobin level, the increases in platelet count, C-reactive protein, and ALT, and coronary artery lesion (P<0.05).@*CONCLUSIONS@#Compared with those without liver damage, the children in the early stage of KD with liver damage tend to develop clinical symptoms early and have higher levels of inflammatory indicators, and they are more likely to have coronary artery lesion and show no response to IVIG treatment.

ABSTRACT

Objective: To investigate the association of blood lead and blood selenium with serum high-sensitivity C-reactive protein (hs-CRP) among Chinese adults aged 19 to 79 years. Methods: The participants were enrolled from the first wave of China National Human Biomonitoring (CNHBM) conducted from 2017 to 2018. 10 153 participants aged 19 to 79 years were included in this study. Fasting blood samples were obtained from participants. Lead and selenium in whole blood and hs-CRP in serum were measured. Individuals with hs-CRP levels above 3.0 mg/L were defined as elevated hs-CRP. Generalized linear mixed models and restricted cubic spline models were used to analyze the association of blood lead and blood selenium with elevated hs-CRP. Logistic regression models were used to analyze the multiplicative scale and additive scale interaction between blood lead and blood selenium on elevated hs-CRP. Results: The age of participants was (48.91±15.38) years, of which 5 054 (61.47%) were male. 1 181 (11.29%) participants were defined as elevated hs-CRP. After multivariable adjustment, results from generalized linear models showed that compared with participants with the lowest quartile of blood lead, the OR (95%CI) of elevated hs-CRP for participants with the second, third, and highest quartiles were 1.14 (0.94-1.37), 1.25 (1.04-1.52) and 1.38 (1.13-1.68), respectively. When compared with participants with the lowest quartile of blood selenium, the OR (95%CI) of elevated hs-CRP for participants with the second, third and highest quartiles were 0.86 (0.72-1.04), 0.91 (0.76-1.11), and 0.75 (0.61-0.92), respectively. Results from the interaction analysis showed no significant interaction between lead and selenium on elevated hs-CRP. Conclusion: Blood concentration of lead was positively associated with elevated serum hs-CRP, and blood concentration of selenium was inversely related to elevated hs-CRP, while blood lead and selenium did not present interaction on elevated hs-CRP.

ABSTRACT

Objective: To explore the application value of T lymphocyte subsets combined with procalcitonin (PCT), C-reactive protein (CRP), neutrophil to lymphocyte ratio (NLR) and white blood cell count (WBC) in the auxiliary diagnosis and prognosis evaluation of sepsis. Methods: In a retrospective study, seventy-two patients with sepsis diagnosed and treated in Tianjin First Central Hospital from June 2018 to April 2021 were selected as the research objects, and included in the sepsis group were 46 males and 26 females, aged 68 (57.3, 80.3) years. In addition, 111 patients with local infection admitted to hospital during the same period were included in the local infection group, including 62 males and 49 females, aged 68 (51, 77) years. Sepsis patients were divided into survival group (43 cases) and death group (29 cases) according to the 28-day outcome. CD3+, CD4+, CD8+, CD4+/CD8+ ratio were detected by flow cytometry within 24 h after admission, PCT was detected by ELISA, CRP was detected by immunoturbidimetry, blood routine examination, blood lactic acid (Lac) and oxygen partial pressure (PO2) were detected by instrumental method. Multivariate Logistic regression analysis was used to evaluate the correlation between each indicator and sepsis, and receiver operating characteristic curve (ROC) was drawn to evaluate the diagnostic value of each indicator for sepsis. Multivariate Logistic regression analysis and Kaplan Meier survival analysis were used to evaluate the prognostic value of each index for patients with sepsis. Results: Peripheral blood CD3+, CD4+, CD8+, CD4+/CD8+ ratio and PLT in sepsis group were significantly lower than those in local infection group(Z=-8.184,P<0.001;Z=-7.210,P<0.001;Z=-5.936,P<0.001;Z=-2.700,P=0.007;Z=-6.381,P<0.001); PCT, CRP, NLR and Lac levels were significantly higher than those in local infection group(Z=-8.262,P<0.001;Z=-3.094,P=0.002;Z=-9.004,P<0.001;Z=-4.770,P<0.001). Multivariate Logistic regression model showed that PCT, NLR, CD3+, CD8+, CD4+/CD8+ were independent risk factors for sepsis. According to ROC curve analysis, AUC of sepsis patients diagnosed by each indicator were 0.862, 0.894, 0.858, 0.760 and 0.618, respectively. The cut-off values were 3.075 ng/ml, 10.715, 44.935×109/L, 27.463×109/L and 0.750, respectively. The NLR sensitivity was 80.6%, and the CD3+ specificity was 94.6%. The AUC of combined detection of PCT and NLR was 0.947, sensitivity was 87.5% and specificity was 91.9%. The combined detection AUC of PCT, NLR, CD3+, CD4+/CD8+ was 0.958, the sensitivity and specificity were 90.3% and 91.0% respectively(P<0.001). PCT and Lac in death group were significantly higher than those in survival group(Z=-2.302,P=0.021;Z=-3.095,P=0.002);Peripheral blood CD4+/CD8+ levels were significantly lower than those in survival group(Z=-3.691,P<0.001),Multivariate Logistic regression model showed that CD4+/CD8+ ratio was an independent risk factor for 28 d mortality in patients with sepsis (P<0.001). The ROC curve showed that the AUC was 0.758, and the Youden index reached the maximum when the cut-off value was 1.27, the sensitivity and specificity were 79.3% and 60.5%, respectively. Compared with patients with CD4+/CD8+ ≥1.27, 28-day mortality was significantly increased in patients with CD4+/CD8+<1.27 (P=0.032). Conclusion: The combined detection of PCT, NLR, CD3+ and CD4+/CD8+ can improve the auxiliary diagnostic efficiency of sepsis, and the ratio of CD4+/CD8+ in peripheral blood may have certain predictive value for the prognosis of sepsis.

ABSTRACT

OBJECTIVES@#With the continuous generation of new variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pressure of epidemic prevention and control continues to increase in China. Omicron with stronger infectiousness, immune escape ability and repeated infection ability spread to many countries and regions around the world in a short period of time. China has also successively reported cases of imported Omicron infections. This study aims to understand the epidemiological characteristics of Omicron variant via analyzing the epidemiological characteristics of imported patients with Omicron in Hunan Province, and to provide reference for preventing and controlling the imported epidemics.@*METHODS@#The clinical data of imported patients with coronavirus disease 2019 admitted to Hunan Province from December 16 to December 31, 2021 were retrospectively collected. The epidemiological information, general information, clinical classification, clinical symptoms, vaccination status, and lung CT were analyzed. Nasopharyngeal swabs and blood samples were collected. Virus nucleic acid was detected by magnetic beads method using SARS-CoV-2 detection kit. Ct values of ORF1ab gene and N gene were compared between asymptomatic infected patients and confirmed patients. The specific IgM and IgG antibodies were detected by chemiluminescence assay using SARS-CoV-2 IgM test kit and SARS-CoV-2 IgG test kit, respectively. Ct values of IgM and IgG antibodies were compared between asymptomatic infected patients and confirmed patients.@*RESULTS@#Seventeen patients with Omicron variant infection were treated in Hunan, including 15 confirmed patients (5 common type and 10 mild type) and 2 asymptomatic infection patients. The 17 patients were all Chinese, they were generally young, and 16 were male. There were 9 patients with diseases. Of them 3 patients had respiratory diseases. All 17 patients had completed the whole process of vaccination, but only one person received a booster shot of SARS-CoV-2 vaccine. The clinical manifestations of the patients were mild, mainly including dry/painful/itchy throat, cough, and fatigue. The total protein and creatine in the asymptomatic infection and confirmed cases infected with Omicron variant were all within the normal range, but other biochemical indicators were abnormal. There were the significant differences in C-reactive protein and fibrinogen between asymptomatic infection and confirmed patients (both P<0.05). There were more patients with elevated C-reactive protein in confirmed patients than without confirmed ones. The detection rate of specific IgM and IgG antibodies on admission was 100%, and there was no significant difference in the specific antibody levels between asymptomatic infection and confirmed patients (P>0.05). There were no significant differences in Ct values of ORF1ab gene and N gene (21.35 and 18.39 vs 19.22 and 15.67) between the asymptomatic infection and the confirmed patients (both P>0.05). Only 3 patients had abnormal lung CT, showing a small amount of patchy and cord-like shadows. One of them had no abnormality on admission but had pulmonary lesions and migratory phenomenon after admission.@*CONCLUSIONS@#The patients with Omicron variant tend to be young people and have milder clinical symptoms, but the viral load is high and the infectiveness is strong. Therefore, the timely identification and effective isolation and control for asymptomatic infections and confirmed patients with mild symptoms are extremely important. In terms of epidemic prevention and control, the government still needs to strengthen the risk control of overseas input, adhere to normalized epidemic prevention and control measures, to effectively control the source of infection, cut off the route of transmission, and protect vulnerable people.

ABSTRACT

OBJECTIVES@#To study the value of heparin-binding protein (HBP) in the diagnosis of severe infection in children.@*METHODS@#This study was a prospective observational study. The medical data of children who were admitted to the pediatric intensive care unit due to infection from January 2019 to January 2020 were collected. According to the diagnostic criteria for severe sepsis and sepsis, the children were divided into a severe sepsis group with 49 children, a sepsis group with 82 children, and a non-severe infection group with 33 children. The three groups were compared in terms of related biomarkers such as plasma HBP, serum C-reactive protein, serum procalcitonin, and platelet count. The receiver operating characteristic (ROC) curve was plotted to investigate the value of plasma HBP level in the diagnosis of severe infection (including severe sepsis and sepsis).@*RESULTS@#The severe sepsis and sepsis groups had a significantly higher plasma HBP level on admission than the non-severe infection group (P<0.05). Compared with the sepsis and non-severe groups, the severe sepsis group had significantly higher serum levels of C-reactive protein and procalcitonin and a significantly lower platelet count (P<0.05). Plasma HBP level had an area under the ROC curve of 0.590 in determining severe infection, with a sensitivity of 38.0% and a specificity of 82.4% (P<0.05).@*CONCLUSIONS@#There is an increase in plasma HBP level in children with severe infection, and plasma HBP level has a lower sensitivity but a higher specificity in the diagnosis of severe infection and can thus be used as one of the markers for the judgment of severe infection in children.

ABSTRACT

OBJECTIVE@#Traditional epidemiological studies have shown that C-reactive protein (CRP) is associated with the risk of cardiovascular diseases (CVDs). However, whether this association is causal remains unclear. Therefore, Mendelian randomization (MR) was used to explore the causal relationship of CRP with cardiovascular outcomes including ischemic stroke, atrial fibrillation, arrhythmia and congestive heart failure.@*METHODS@#We performed two-sample MR by using summary-level data obtained from Japanese Encyclopedia of Genetic association by Riken (JENGER), and we selected four single-nucleotide polymorphisms associated with CRP level as instrumental variables. MR estimates were calculated with the inverse-variance weighted (IVW), penalized weighted median and weighted median. MR-Egger regression was used to explore pleiotropy.@*RESULTS@#No significant causal association of genetically determined CRP level with ischemic stroke, atrial fibrillation or arrhythmia was found with all four MR methods (all Ps > 0.05). The IVW method indicated suggestive evidence of a causal association between CRP and congestive heart failure ( OR: 1.337, 95% CI: 1.005-1.780, P = 0.046), whereas the other three methods did not. No clear pleiotropy or heterogeneity were observed.@*CONCLUSIONS@#Suggestive evidence was found only in analysis of congestive heart failure; therefore, further studies are necessary. Furthermore, no causal association was found between CRP and the other three cardiovascular outcomes.

ABSTRACT

Introduction: The literature converges regarding the use of C-reactive protein (CRP) tests between postoperative days (PODs) 3 and 5 of elective procedures. In this period, they have great sensitivity and negative predictive value (NPV) for severe and anastomotic complications about two days before the first clinical sign. The few studies on colorectal urgency suggest that, despite the different initial values according to the surgical indication, following POD 3, the level of CRP is similar to that of elective procedures. However, given the heterogeneity of the studies, there is no consensus on the cutoff values for this use. Objective: To validate the use and propose a PO CRP cut-off value in urgent colorectal procedures as an exclusion criterion for complications of anastomosis or the abdominal cavity. Method: Retrospective analysis of the medical records of 308 patients who underwent urgent colorectal surgical procedures between January 2017 and December 2019. The following data were considered: age, gender, surgical indication, type of procedure performed, complications, CRP levels preoperatively and from POD 1 to 4, and the severity of the complications. We compared the CRP levels and the percentage variations between the preoperative period and PODs 1 to 4 as markers of severe complications using the receiver operating characteristic (ROC) curve. Results: The levels of CRP on POD4, and their percentage drops between PODs 2 to 4 and PODs 3 to 4, were better to predict severe complications. A cutoff of 7.45mg/dL on POD 4 had 91.7% of sensitivity and NPV. A 50% drop between PODs 3 and 4 had 100% of sensitivity and NPV. Conclusion: Determining the level of CRP is useful to exclude severe complications, and it could be a criterion for hospital discharge in POD 4 of emergency colorectal surgery. (AU)

ABSTRACT

Abstract Objective: To evaluate the diagnostic utility of salivary C-reactive protein (CRP) and its potential correlation with serum CRP levels in full-term neonates with late-onset sepsis (LOS). Methods: This cross-sectional study included 90 neonates assigned to three equal groups: culture proven LOS, clinical LOS and a control group. Clinical findings and routine laboratory data including complete blood pictures and blood culture results were documented. Highly sensitive serum CRP was measured according to hospital protocol, while salivary CRP levels were measured using enzyme-linked immunosorbent assay. Results: The median serum CRP was significantly higher in septic neonates compared to controls (p < 0.001). For serum CRP, the optimum cut-off value for LOS diagnosis was found to be 7.2 mg/L with sensitivity, specificity, positive and negative predictive values of 91, 100, 100, and 85.7%, respectively. No significant difference was observed in levels of salivary CRP among the 3 study groups (p = 0.39). No correlation was found between the levels of salivary and serum CRP (r = 0.074, p = 0.49). Conclusion: Serum CRP, at a cut-off value of 7.2 mg/L, exhibited a high specificity and positive predictive value in LOS diagnosis, whereas salivary CRP levels weren't significantly different between the 3 study groups nor did they predict abnormal serum CRP thresholds in newborns with sepsis.
