Association between pre-operative high sensitive C-reactive protein and immediate post-operative radicular pain following prolapsed lumbar intervertebral disc surgery

Background: Nerve root compression is often inadequately understanding radicular pain due to prolapsed lumbar intervertebral disc, a common neurosurgical presentation. Inflammation is proved as an important etio-pathological component of radiculopathy, even after surgery. Methods: This cross-sectional intervention study conducted from March 2022 to September 2023. Data collected from 45 patients with prolapsed lumber intervertebral Disc, who underwent surgical intervention in Department of Neurosurgery, BSMMU. Results: The mean±SD age of the patients was 38.4±11.6 years, most of them 37 (82.2%) aged within 29 to 60 years. Majority 30 (66.7%) of them were male. Patients presented with pain, numbness and weakness was 45 (100%), 33 (73.3%) and 8 (17.8%) respectively. Among the participants most 36 (80%) had right sided and 9 (20%) had left sided radiation. The mean±SD level of pre-operative high sensitive C-reactive protein was 2.1±1.7. Pre-operative high sensitive C-reactive protein was significantly associated pre-operative, post-operative and mean change in visual analogue score (p<0.001, p<0.001, p= 0.006 respectively). Correlation of high sensitive C-reactive protein and VAS score (both pre and post-operative) were also statistically significant with p =0.017 and p <0.001 respectively. Conclusions: In our study, there is an association between pre-operative serum high sensitive C- reactive protein and post-operative radicular pain following surgical intervention in patients with prolapsed lumbar intervertebral disc.

Proteína C reactiva, aspectos cardiovasculares de una proteína de fase aguda: una actualización para el médico / C-reactive protein, cardiovascular issues of an acute-phase protein: an update for the clinician

Resumen La inflamación es un factor patogénico importante para el desarrollo de la enfermedad cardiovascular aterosclerótica. Actualmente, el biomarcador utilizado con mayor frecuencia que refleja la inflamación sistémica es la proteína C reactiva (PCR), una proteína de fase aguda producida principalmente por los hepatocitos bajo la influencia de la interleucina 6, la interleucina 1 beta y el factor de necrosis tumoral. La evidencia proveniente de estudios epidemiológicos ha demostrado una fuerte asociación entre las concentraciones elevadas de PCR en suero o plasma y la incidencia de un primer evento cardiovascular (incluido infarto agudo de miocardio, accidente vascular cerebral isquémico y muerte cardíaca súbita) en la población general, así como la recurrencia de eventos cardiovasculares adversos en los pacientes con enfermedad establecida. El valor aditivo que la medición de la PCR otorga a los factores de riesgo tradicionales se refleja en novedosas calculadoras de riesgo cardiovascular y en los actuales regímenes de intervención, que ya consideran a la PCR como objetivo terapéutico. Sin embargo, las variaciones en los niveles de PCR, que dependen del sexo, la etnia, el estado hormonal y algunas peculiaridades de los ensayos de medición, deben tenerse en cuenta al decidir implementar la PCR como un biomarcador útil en el estudio y el tratamiento de la enfermedad cardiovascular aterosclerótica. Esta revisión pretende ofrecer una visión actualizada de la importancia de medir la PCR como biomarcador de riesgo cardiovascular más allá de los factores tradicionales que estiman el riesgo de enfermedad aterosclerótica.

Abstract Inflammation is an important pathogenic factor for the development of atherosclerotic cardiovascular disease. Currently, the most frequently used biomarker reflecting systemic inflammation is C-reactive protein (CRP), an acute-phase protein produced primarily by hepatocytes under the influence of interleukin-6, interleukin-1 beta, and tumor necrosis factor. Growing evidence from epidemiological studies has shown a robust association between elevated serum or plasma CRP concentrations and the incidence of a first cardiovascular adverse event (including acute myocardial infarction, ischemic stroke, and sudden cardiac death) in the general population, as well as recurrence of major adverse cardiovascular events among patients with established disease. The additive value that CRP measurement gives to traditional risk factors is reflected in novel cardiovascular risk calculators and in current intervention regimens, which already consider CRP as a target therapeutic. However, the variations in CRP levels, that depend on sex, ethnicity, hormonal status, and some peculiarities of the measurement assays, must be taken into consideration when deciding to implement CRP as a useful biomarker in the study and treatment of atherosclerotic cardiovascular disease. This review aims to offer an updated vision of the importance of measuring CRP levels as a biomarker of cardiovascular risk beyond the traditional factors that estimate the risk of atherosclerotic disease.

Abstract Background: The administration of colostrum through its absorption at the oropharyngeal level stimulates the mucosa-associated lymphoid tissue, providing a local immunological protection barrier. The study aimed to investigate the association of oropharyngeal colostrum administration with the reduction of inflammatory indices. Materials and methods: This was an observational, ambispective, analytical study of newborns < 32 weeks of gestation at risk of sepsis. Oropharyngeal colostrum was administered at 0.2 mL every 4 h for 5 days. Inflammatory indices were analyzed. Statistical analysis included frequencies, percentages, mean and Standard deviation, contingency coefficient, and Kolmogorov–Smirnov test for the distribution curve of the numerical data. Results: There were 50 patients, 33 (66%) female and 17 (34%) male, with a median gestational age of 30-31 weeks (95% confidence interval [CI]). Nineteen patients had sepsis. A lower positivity rate in C-reactive protein was found, with a median of 0.5-0.6 (95% CI) at 5 days of colostrum administration versus 0.5-1.1 (95% CI) as the initial C-reactive protein. Analysis with χ2 yielded a p = 0.13, and the contingency coefficient showed a p = 0.196, indicating an association. Conclusion: Oropharyngeal colostrum administration was associated with a lower C-reactive protein positivity rate and clinical improvement in premature newborns at risk of sepsis.

Profile of adenoviral infection in hospitalized children

This single-center, retrospective study was conducted at Marengo Asia Hospital, Haryana from January 2023 to November 2023. Children aged 1 month to 16 years, admitted with a positive adenovirus polymerase chain reaction (nasopharyngeal swab) were included. Symptomatic management was provided to all children. The study focuses on discussing the demographic, clinical, laboratory and radiological profiles of hospitalized children with human adenovirus infection. Among the 25 children with a positive adenovirus polymerase chain reaction, 18 (72%) were males, 15 (60%) were within the age group of 1 month to 5 years. Furthermore, 13 (52%) children were hospitalized during summer season. The most prevalent symptoms observed in children admitted with adenovirus infection were high-grade persistent fever in 25 cases (100%), cough and cold in 15 cases (60%), 14 (56%) vomiting in 14 cases (56%), pain abdomen and loose stools in 10 cases (40%), conjunctivitis in 6 cases (24%), and adenoviral pneumonia in 4 cases (16%). Notably all children were discharged successfully without encountering any complications. HAdV infections are commonly associated with high- grade fever, challenging the conventional perception that respiratory infections are their predominant manifestation. Equally noteworthy is the prevalence of gastrointestinal symptoms in HAdV infections

Proteína-C reactiva de alta sensibilidad y homocisteína en pacientes con enfermedad cerebrovascular isquémica

Fundamento: la proteína C reactiva de alta sensibilidad (PCR-as) y la homocisteína (Hci) parecen relacionarse con la enfermedad cerebrovascular isquémica, pero sus hallazgos sobre el riesgo y pronóstico de esta enfermedad resultan controversiales y no concluyentes. Objetivo caracterizar la proteína C reactiva de alta sensibilidad y homocisteína en pacientes con enfermedad cerebrovascular isquémica. Métodos: se realizó un estudio descriptivo y retrospectivo de corte transversal en pacientes con enfermedad cerebrovascular isquémica, ingresados en el Servicio de Ictus del Instituto de Neurología y Neurocirugía entre 2016 y 2019. Se recogieron variables demográficas, manifestaciones clínicas, tiempo de evolución, etiología y localización del infarto y factores riesgo. Se cuantificaron la PCR-as (riesgo cardiovascular) y la Hci. Resultados las medias de PCR-as (7,0±8,3 mg/L) y Hci (17,1±7,3 µM) fueron elevadas. El riesgo cardiovascular moderado y alto se presentaron en igual proporción (46,8 %). Hubo diferencias estadísticas en la relación entre el riesgo cardiovascular y la edad (p=0,00); pero ni el tiempo de evolución ni los factores de riesgo de la enfermedad mostraron este comportamiento. Los pacientes con riesgo cardiovascular alto (PCR-as >3 mg/L) y elevada Hci (>15 (M) exhibieron mayores frecuencias de etiologías aterotrombótica o cardioembólica. Conclusiones el riesgo cardiovascular aumenta en la medida que se incrementa la edad de pacientes con enfermedad cerebrovascular isquémica. Las características demográficas, clínicas y neurológicas no mostraron relación con el alto riesgo cardiovascular y los valores elevados de Hci, aunque se encontró una tendencia asociativa de la etiología aterotrombótica con el incremento de PCR-as y Hci.

Foundation: High-sensitivity C-reactive protein and homocysteine seem to be related to ischemic cerebrovascular disease, but their findings on the risk and prognosis of this disease are controversial and inconclusive. Objective: to characterize high sensitivity C-reactive protein and homocysteine in patients with ischemic cerebrovascular disease. Methods: a descriptive and retrospective cross-sectional study was carried out in patients with ischemic cerebrovascular disease, admitted to the Stroke Service of the Neurology and Neurosurgery Institute between 2016 and 2019. Demographic variables, clinical manifestations, time of evolution, etiology and infarction location, risk factors. High-sensitivity C-reactive protein (cardiovascular risk) and homocysteine were quantified. Results: the means of C-reactive protein (7.0±8.3 mg/L) and homocysteine (17.1±7.3 µM) were high. Moderate and high cardiovascular risk occurred in equal proportions (46.8%). There were statistical differences in the relationship between cardiovascular risk and age (p=0.00); but neither the time of evolution nor the risk factors of the disease showed this behavior. Patients with high cardiovascular risk (hs-CRP >3 mg/L) and high homocysteine (>15 (M), exhibited higher frequencies of atherothrombotic or cardioembolic etiologies. Conclusions: cardiovascular risk increases as the age of patients with ischemic cerebrovascular disease increases. Demographic, clinical and neurological characteristics did not show a relationship with high cardiovascular risk and high homocysteine values, although an associative trend of atherothrombotic etiology was found with increased high-sensitivity C-reactive protein and homocysteine.

Objective To explore the association between C-reactive protein/albumin ratio(CAR)and the risk of cardiovascular events in maintenance hemodialysis(MHD)patients.Methods This study enrolled MHD patients who were treated in the blood purification center of the Second Affiliated Hospital of Guangzhou Medical University between August 2016 to December 2019,and the follow-up deadline was March 31,2021.Collected the clinical data of patients who conform to the inclusion criteria,including demographic,complications,primary basic disease,biochemical indicators of the patients who underwent 3 months regular dialysis treatment and the occurrence of cardiovascular events during the follow-up period.The Kaplan-Meier method was used to estimate the probability of cardiovascular incidents in MHD patients.The Cox proportional hazards model based on generalized propensity score weighting(GPSW)was used to estimate the relationship between CAR and cardiovas-cular events in MHD patients.Results A total of 170 eligible objects were included in this study,64 patients with cardiovascular events(37.6%).The Cox proportional hazards model which based on GPSW(HRCAR = 2.087,95%CI:1.085～4.015,P = 0.028),indicated that the hazard ratio of cardiovascular events was 2.087 when the CAR each additional a unit in MHD patients.Conclusion CAR and the risk of cardiovascular events in MHD patients have a significant positive correlation,which can help clinical workers recognize the MHD patients who have high risk of cardiovascular events and intervene in time.

Topical application of vancomycin in prevention of early incision infection in total knee arthroplasty / 中国组织工程研究

BACKGROUND:The use of vancomycin in total knee arthroplasty is a controversial strategy for the prevention of incisional infection.At present,there is little evidence to evaluate the efficacy of this preventive measure in China. OBJECTIVE:To evaluate the efficacy of local vancomycin in the prevention of early postoperative incision infection during total knee arthroplasty. METHODS:120 patients with osteoarthritis of the knee who received unilateral total knee arthroplasty for the first time at Department of Joint Surgery of First Affiliated Hospital of Anhui Medical University from March to June 2022 were included in this study.They were randomly divided into the observation group and the control group,with 60 cases in each group.All patients gave informed consent to the treatment plan.In the observation group,1 g of vancomycin was applied intraoperatively;in the control group,no vancomycin was applied intraoperatively.Erythrocyte sedimentation rate,C-reactive protein,fever rate on seven consecutive days after surgery,degree of knee joint swelling,cumulative drainage volume,and incidence of periprosthetic joint infection were recorded in two groups of patients on days 1,3,and 5 after surgery so as to evaluate the efficacy of topical vancomycin in total knee arthroplasty for the prevention of incision infection in the early postoperative period. RESULTS AND CONCLUSION:(1)The differences in erythrocyte sedimentation rate and C-reactive protein between the two groups on days 1,3,and 5 after surgery were not significant(P>0.05).(2)The difference in fever rate between the two groups for 7 consecutive days after surgery was not significant(P>0.05).(3)There was no significant difference in the degree of postoperative knee swelling and cumulative drainage flow between the two groups(P>0.05).(4)The difference in the incidence of periprosthetic joint infection one year after surgery was not significant between the two groups(P>0.05).(5)The results suggest that the local use of vancomycin in total knee arthroplasty has not shown significant efficacy in preventing incision infection in the early postoperative period.

Role of inflammatory factors in diabetic ulcers and prospects of traditional Chinese medicine intervention / 中国组织工程研究

BACKGROUND:Diabetic ulcers are a common complication of diabetes mellitus,which is manifested as foot ulcers complicated with infection,long treatment cycle,high disability rate and mortality rate,and brings a heavy burden to patients and social care. OBJECTIVE:To review the mechanism of action and the latest treatment progress of traditional Chinese medicine(TCM)in the treatment of diabetic ulcers,and to provide a basis for further theoretical research and clinical application. METHODS:CNKI,WanFang Database and PubMed database were searched for relevant literature using the keywords of"diabetic ulcer,medicinal herb,inflammation,interleukin-1β,interleukin-6,tumor necrosis factor,hypersensitive C-reactive protein,γ-interferon,interleukin-4,interleukin-10"in Chinese and English,respectively.The relevant literature in recent years was searched,and finally 75 articles were included for review. RESULTS AND CONCLUSION:The high glucose environment of the body will increase the level of pro-inflammatory cytokines,so that diabetic ulcer wounds are in a state of chronic inflammatory response for a long time,and difficult to heal or even not heal.TCM has summed up a lot of experience in the long-term struggle with diabetic ulcer.At present,TCM divides diabetic ulcers into four syndrome types:dampness and heat poison syndrome,blood and blood stasis obstruction pattern,heat poison injury Yin pattern,and Qi and blood deficiency syndrome,as well as representative prescriptions for treatment.According to their clinical characteristics,diabetic ulcers can be also divided into three stages:primary,middle and late stages.Different treatment methods are proposed:"clear method,""warm and clear combined use"and"maintenance method."Under the guidance of dialectical typing and staging of TCM,TCM monomers,extracts and compounds inhibit the inflammatory response and promote the healing of diabetic ulcers by down-regulating the expression of pro-inflammatory factors and/or up-regulating the expression of anti-inflammatory factors.Compared with modern medicine,TCM has significant advantages in the treatment of diabetic ulcers.There are many TCM monomers,extracts and compounds for the treatment of diabetic ulcers,such as angelica,curcumin,improved Chonghe ointment,Sanhuang blood exhaustion prescription and sore-ulcer I.formula,etc.It has been found that TCM for the treatment of diabetic ulcers is mainly heat-clearing and detoxifying,invigorating blood circulation and removing blood stasis,and amassing sores and muscle-building drugs,and the frequency of use,treatment scope and therapeutic effect of TCM compounds are obviously better than those of TCM monomers and extracts.Among them,the most commonly used are the Sanhuang blood exhaustion prescription and the sore-ulcer I as well as prescription for the treatment of damp heat toxicity syndrome and Zizhu ointment for the treatment of non-ischemic diabetic ulcers.However,there are also some shortcomings in the treatment of diabetic ulcers with TCM.First,there are few clinical syndrome studies on diabetic ulcers.Secondly,there are a wide variety of TCM monomers,extracts and compounds for the treatment of diabetic ulcers,and the relevant research is insufficiently in-depth.Finally,the research on the mechanism underlying TCM treatment of diabetic ulcers is still in the preliminary exploration stage,and the mechanism of action still needs to be further explored.In the future,it is necessary to strengthen the research on the pharmacology of TCM and the clinical syndrome of diabetic ulcers,analyze the potential targets and related signaling pathways of TCM in the treatment of diabetic ulcers,give full play to the therapeutic advantages of TCM with multiple targets,multiple pathways,multiple levels and multiple systems,and develop TCM with significant efficacy,active ingredients and clear targets.

Objective:To explore the application of C-reactive protein(CRP) to prealbumin (PA) ratio(CRP/PA) for diagnosis and prognosis evaluation of sepsis.Methods:By a retrospective study, a total of 95 sepsis patients (sepsis group) and 100 local infection patients(non-sepsis group) treated in Dongying People′s Hospital from September 2021 to September 2022 were enrolled. Sepsis patients were divided into survival group(57 cases) and death group (38 cases) according to the 28-day outcome. The clinical data were collected and CRP/PA was calculated. Multivariate Logistic regression and Cox regression were used to analyze the relationship between various indicators and the occurrence and prognosis of sepsis, and receiver operating characteristic (ROC) curve was drawn to evaluate the diagnostic and prognostic value of CRP/PA for sepsis. Kaplan-Meier survival analysis was used to evaluate the prognostic value of different CRP/PA ratios for patients with sepsis.Results:The systolic blood pressure, diastolic blood pressure, prealbumin were lower and heart rate, respiratory rate, CRP, CRP/PA, procalcitonin were higher in the sepsis group compared to the non-sepsis group: (117.27 ± 11.65) mmHg (1 mmHg = 0.133 kPa) vs. (123.26 ± 10.71) mmHg, (69.42 ± 8.58) mmHg vs. (75.44 ± 6.53) mmHg, (174.09 ± 24.77) g/L vs. (207.13 ± 34.31) g/L, (97.87 ± 12.73) bpm vs. (86.90 ± 10.19) bpm, 22.0(20.00, 25.00) times/min vs. 21.00(19.00, 23.00) times/min, (93.96 ± 19.64) mg/L vs. (77.56 ± 22.54) mg/L, 0.54(0.44, 0.65) vs. 0.37(0.28, 0.46), 3.35(2.16, 4.17) μg/L vs. 1.52(0.81, 2.16) μg/L, there were statistical differences ( P<0.05). Multivariate Logistic regression analysis showed that CRP/PA and procalcitonin were risk factors for sepsis ( P<0.05). The results of ROC curve showed that the area under the curve (AUC) of CRP/PA in diagnosis of sepsis was 0.821, the specificity and sensitivity was 76.0% and 93.7%, respectively. The diastolic blood pressure, prealbumin, neutrophil were higher and the heart rate, respiratory rate, CRP, CRP/PA, lymphocytes, procalcitonin were lower in the survival group compared to the death group: (71.76 ± 8.86) mmHg vs. (67.86 ± 8.10) mmHg, (181.46 ± 24.35) g/L vs. (163.05 ± 21.28) g/L, (63.46 ± 9.88) × 10 9/L vs.(57.13 ± 8.64) × 10 9/L, (95.68 ± 13.48) times/min vs. (101.16 ± 10.88) times/min, 22.00(19.50, 24.00) times/min vs. 24.00(20.00, 28.00) times/min, (88.09 ± 19.35) mg/L vs. (102.76 ± 16.75) mg/L, 0.46(0.41, 0.58) vs. 0.63(0.55, 0.72), 21.00(16.00, 30.00) ×10 9/L vs. 29.50(18.00, 37.30) ×10 9/L, 2.94(2.10, 3.97) μg/L vs. 3.82(2.21, 4.77) μg/L, there were statistical differences ( P<0.05). Multivariate Cox regression analysis showed that CRP/PA and procalcitonin were independent risk factors for the prognosis of sepsis ( P<0.05). The AUC of CRP/PA in predicting the prognosis of sepsis was 0.827, the specificity and sensitivity was 92.1% and 63.8%, respectively. Grouped by the cut-off of CRP/PA (0.48), the 28-day mortality rate of patients in the CRP/PA>0.48 was significantly higher than that of patients in the CRP/PA≤0.48, there was statistical difference ( P<0.01). Conclusions:CRP/PA ratio can be used as an index for diagnosis and prognosis evaluation of sepsis.

Objective:To explore the the evaluation value of stress hyperglycemia ratio (SHR), C-reactive protein (CRP), and serum procalcitonin (PCT) for postoperative infection in patients with open tibiofibular fractures.Methods:This study was a prospective analysis. Patients with open tibiofibular fractures hospitalized in the Department of Orthopaedic Surgery of The Second Hospital of Tangshan and North China University of Science and Technology Affiliated Hospital from January 2018 to January 2023 were collected as the research objects, and a total of 839 cases were assessed for outcome, which were divided into infection group (103 cases) and non-infection group (736 cases) according to whether the selected subjects had postoperative infection. The clinical data of the two groups were analyzed by univariate analysis, and the risk factors of postoperative infection of open fracture of tibia and fibula were analyzed by multivariate Logistic regression, and the receiver operating characteristic (ROC) curve was drawn to analyze the predictive efficacy of SHR, CRP, PCT, and their combined models on adverse outcomes.Results:Univariate analysis showed that the infection group had SHR (1.82±0.31), CRP (92.28±36.07) mg/L, PCT (6.35±1.79) μg/L, the non infection group had (1.05±0.12), (56.35±10.21) mg/L and (2.17±0.41) μg/L, respectively, and there were significant differences between the two groups ( t values were 46.90, 21.60, and 54.17, respectively; all P<0.001). The proportion of albumin (<30 g/L) in the infection group was higher than that in the non-infection group (63.11%(65/103), 37.64%(277/736) (χ 2=24.28, P<0.001), and the two groups had significant differences in the rate of time from injury to operation (the infection group ≥6 h was 71.84%(74/103), <6 h was 28.16%(29/103); the non-infection group ≥6 h was 43.07%(317/736), <6 h was 56.93%(419/736); χ 2=35.37, P<0.001), the rate of Gustilo-Anderson classification (the infection group Ⅰ、Ⅱ was 44.46%(46/103), ⅢA was 33.98%(35/103), ⅢB was 12.62%(13/103), ⅢC was 8.47%(9/103);the non-infection groupⅠ、Ⅱ was 59.10%(435/736), ⅢA was 32.47%(239/736), ⅢB was 5.98%(44/736), ⅢC was 2.45%(18/736); χ 2=20.34, P<0.001) and the rate of postoperative drainage volume (the infection group was 40.60%(48/103),the non-infection group was 58.02%(427/736); χ 2=4.79, P=0.029). Multivariate Logistic regression analysis showed that SHR ( OR=1.871,95% CI 1.621-2.160, P<0.001), CRP ( OR=1.060, 95% CI 1.015-1.107, P=0.009), PCT ( OR=1.497, 95% CI 1.420-1.577, P<0.001) were independent risk factors for postoperative infection in open tibiofibular fractures. Among them, SHR had the highest OR value, which was the strongest factor affecting the outcome of the study. Other independent factors were age ( OR=1.052, 95% CI 1.038-1.066, P<0.001) and Gustilo-Anderson type-ⅢC ( OR=1.875, 95% CI 1.038-2.015, P<0.001). By drawing the ROC curve of SHR, CRP, PCT and their combined model to predict the incidence of postoperative infection in open tibiofibular fractures, the results showed that the combined model had higher diagnostic predictive value than the single application, and its sensitivity and specificity were 86.4% and 70.4%, respectively, which were higher than the sensitivity (78.6%, 77.7%, 75.7%) and specificity (69.2%, 69.3%, 69.6%) of the single assessment. Conclusion:The combined model of SHR, CRP and PCT has a higher predictive value than the single detection, which can provide a better clinical basis for the early diagnosis of postoperative infection in patients with open tibiofibular fractures.
