The Effects of Perineural Dexamethasone on Rebound Pain After Nerve Block in Patients With Unicompartmental Knee Arthroplasty: A Randomized Controlled Trial.

A single nerve block provides excellent analgesia in a short time, but rebound pain after the nerve block dissipates has attracted researchers' attention. The aim of this study was to evaluate the effect of perineural dexamethasone on rebound pain after sciatic nerve block and femoral nerve block in patients undergoing unicompartmental knee arthroplasty (UKA). In a double-blinded fashion, we recruited 72 patients undergoing UKA, each of whom received sciatic and femoral nerve block. Patients were randomly assigned to 2 groups (n=36): X (ropivacaine only) and D (ropivacaine combined with dexamethasone). The primary outcome was the incidence of rebound pain. The secondary outcomes were rebound pain score, the duration of rebound pain, the duration of nerve block, pain score, sufentanil consumption and rescue analgesic, patient-controlled intravenous analgesia, distance walked, sleep quality score, C-reactive protein levels, and adverse effects. Compared with group X, the incidence of rebound pain in group D was higher, the rebound pain score was higher and the duration of the nerve block was prolonged ( P <0.05). At 12, 16, and 20 hours postoperatively, the pain scores at rest in group D were lower. At 32 and 36 hours postoperatively, the pain scores at rest in group D were higher ( P <0.05). Furthermore, patients in group D had lower levels of C-reactive protein after surgery ( P <0.05). The addition of dexmedetomidine to ropivacaine for UKA effectively prolonged the duration of nerve block and decreased C-reactive protein levels, but increased the incidence of rebound pain and rebound pain score, and had no beneficial effects on the postoperative analgesia.

Factors influencing antibiotic prescribing for respiratory tract infections in primary care – a comparison of physicians with different antibiotic prescribing rates

Background There has been a notable decrease in antibiotic prescribing in the last thirty years in Sweden. Little is known about factors influencing antibiotic prescribing over several years. Objective To compare primary care physicians who, over time, reduced their antibiotic prescribing for respiratory tract infections with those who remained either high or low prescribers regarding potentially influencing factors. Design and setting A register-based study including all RTI visits in primary care in Region Kronoberg, Sweden 2006–2014. The data were divided into three 3-year periods. Subjects The data comprised all physicians who had diagnosed at least one RTI for each of the three-year periods. The antibiotic prescribing rate adjusted for the patients’ sex and age group was calculated for each physician and period, and based on the change between the first and the third period, the physicians were divided into three prescriber groups: The High Prescribing Group, the Decreasing Prescribing Group, and the Low Prescribing Group. Main outcome measures For the three prescriber groups, we compared factors influencing antibiotic prescribing such as the characteristics of the physicians, their use of point-of-care tests, their choice of diagnoses, and whether the patients returned and received antibiotics. Results The High Prescribing Group ordered more point-of-care tests, registered more potential bacterial diagnoses, prescribed antibiotics at lower C-reactive protein levels, and prescribed antibiotics more often despite negative group A Streptococci test than in the Low Prescribing Group. The Decreasing Prescribing Group was between the High Prescribing Group and the Low Prescribing Group regarding these variables. The lower prescription rate in the Low Prescribing Group did not result in more return visits or new antibiotic prescriptions within 30 days. Conclusion Point-of-care testing and its interpretation differed between the prescriber groups. Focus on interpreting point-of-care test results could be a way forward in antibiotic stewardship.

Feasibility of Robot-Assisted Cytoreductive Surgery With Upper-Abdominal Peritonectomy for Pseudomyxoma Peritonei With Low Peritoneal Carcinomatosis Index: A Pilot Study.

Our study's objective was to provide the method for, and preliminary findings from, robot-assisted cytoreductive surgery (r-CRS) combined with upper-abdominal peritonectomy in pseudomyxoma peritonei (PMP) with limited peritoneal surface malignancy (PSM). We conducted a retrospective pilot study on consecutive patients with PSM secondary to pseudomyxoma peritonei with a peritoneal cancer index (PCI) of under 10 who were indicated for r-CRS combined with upper-abdominal peritectomy. Perioperative and 30-day major morbidity and mortality characteristics were analyzed and compared with cases in which laparoscopic CRS (l-CRS) was performed under the same conditions. Six patients underwent r-CRS combined with an upper-abdominal partial peritonectomy. Their mean PCI was 4.83. Complete cytoreduction was achieved in all patients. The mean duration of the operation was 156.8 minutes. There was no major complication and no mortality. The mean length of hospital stay after surgery was 6.33 days. r-CRS resulted in less blood loss, a lower C-reactive protein level, and a shorter length of hospital stay that were significantly different compared with those of l-CRS. This is the initial technical report of a robotic approach for CRS combined with upper-abdominal peritonectomy. r-CRS with a combined upper-abdominal peritonectomy was shown to be safe and feasible for PMP with limited PSM.

The association between religious beliefs and values with inflammation among Middle-age and older adults

Objectives: Dimensions of religion and spirituality are associated with better emotional, physical, and cognitive health. However, the underlying physiological mechanisms are not well known. We investigated the relationship between dimensions of religion and spirituality with levels of C-reactive protein (CRP), a biomarker of systematic inflammation, in middle-aged and older adults in the United States.Methods: In this descriptive longitudinal study using secondary data, we used proportional odds models of the generalized estimating equation (GEE) to assess the association between religious beliefs and values and religious service attendance with CRP levels from respondents (n = 2,385) aged 50 years and older in the Health and Retirement Study from 2006 to 2014.Results: Middle-aged to older adults who reported higher religious beliefs and values had lower levels of CRP, controlling for age, sex, education, marital status, race, household income, and health, such as hypertension, diabetes, cancer, and body mass index (BMI).Conclusion: Religious beliefs and values are associated with lower CRP levels among middle-aged and older adults in the U.S. This study adds to the understanding of biological processes underlying the relationship between dimensions of religion and spirituality with better cognitive and physical health, potentially through inflammation.

CRP under 130 mg/L rules out the diagnosis of Legionella pneumophila serogroup 1 (URINELLA Study)

IntroductionIn case of pneumonia, some biological findings are suggestive for Legionnaire’s disease (LD) including C-reactive protein (CRP). A low level of CRP is predictive for negative Legionella Urinary-Antigen-Test (L-UAT).MethodObservational retrospective study in Nord-Franche‐Comté Hospital with external validation in Besançon University Hospital, France which included all adults with L-UAT performed during January 2018 to December 2022. The objective was to determine CRP optimal threshold to predict a L-UAT negative result.ResultsURINELLA included 5051 patients (83 with positive L-UAT). CRP optimal threshold was 131.9 mg/L, with a negative predictive value (NPV) at 100%, sensitivity at 100% and specificity at 58.0%. The AUC of the ROC-Curve was at 88.7% (95% CI, 86.3–91.1). External validation in Besançon Hospital patients showed an AUC at 89.8% (95% CI, 85.5–94.1) and NPV, sensitivity and specificity was respectively 99.9%, 97.6% and 59.1% for a CRP threshold at 131.9 mg/L; after exclusion of immunosuppressed patients, index sensitivity and NPV reached also 100%.ConclusionIn case of pneumonia suspicion with a CRP level under 130 mg/L (independently of the severity) L-UAT is useless in immunocompetent patients with a NPV at 100%. We must remain cautious in patients with symptoms onset less than 48 h before CRP dosage.

Effects of moderate ethanol exposure on risk factors for cardiovascular disease and colorectal cancer in adult Wistar rats

While past studies have provided evidence linking excessive alcohol consumption to increased risk for cardiovascular diseases (CVDs) and colorectal cancer (CRC), existing data on the effects of moderate alcohol use on these conditions have produced mixed results. The purpose of this study was to investigate the effects of moderate alcohol consumption on risk factors associated with the development of CVDs and CRC in adult rats. Twenty-four, 14-month-old, non-deprived male Wistar rats were randomly assigned to either an ethanol group, which consisted of voluntary access to a 20% (v/v) ethanol solution on alternate days, or a water control group (n = 12/group) for 13 weeks. Blood samples were collected to analyze levels of albumin, glucose, adiponectin, lipids, oxidized low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (apoA1), C-reactive protein (CRP), high-mobility group box 1 protein (HMGB-1), tumor necrosis factor-alpha (TNF-α), thyroxine, thyroid-stimulating hormone, 8-oxo-2′-deoxyguanosine (8-oxo-dG), liver function enzymes, and antioxidant capacity. Colonic gene expression related to colon carcinogenesis was also assessed. Ethanol-treated rats were found to have significantly higher HDL-C and apoA1 levels compared to controls. Moderate alcohol consumption led to significantly lower CRP levels and a trend for decrease in HMGB-1, TNF-α, and 8-oxo-dG levels. In the ethanol-exposed group, colonic gene expression of superoxide dismutase was upregulated while aldehyde dehydrogenase 2 showed a trend for increase compared to the control group. These results indicate that adopting a moderate approach to alcohol consumption could potentially improve health biomarkers related to CVD and CRC by increasing HDL-C levels and antioxidant activity and reducing DNA damage and inflammatory activity.

Characterization of primary small intestinal lymphoma: a retrospective study based on double balloon endoscopy

BackgroundThe diagnosis of primary small intestinal lymphoma (PSIL) is difficult. This study aimed to evaluate the clinical, radiological and endoscopic characteristics of PSIL and provide clue for diagnosis.MethodsA total of 30 patients diagnosed with PSIL who underwent double balloon endoscopy (DBE) in the First Affiliated Hospital of Zhejiang University were retrospectively analyzed. Clinical, radiological and endoscopic data were collected. Univariate analysis was used to determine significant indicators for differentiating three main subtypes of PSIL. Cox regression analysis was performed to assess the risk factors for survival.ResultsIn this study, 10 patients were pathologically diagnosed as diffuse large B-cell lymphoma (DLBCL), 11 were indolent B-cell lymphoma (BCL) and 9 were T-cell lymphoma (TCL). Compared with DLBCL patients, the body mass index (BMI) of TCL patients was significantly lower (p = 0.004). Meanwhile, compared with patients with DLBCL, the patients with indolent BCL had lower levels of C-reactive protein, lactate dehydrogenase (LDH), fibrinogen and D-Dimer (p = 0.004, p = 0.004, p = 0.006, and p = 0.002, respectively), and lower proportion of thicker intestinal wall and aneurysmal dilation in CT scan (p = 0.003 and p = 0.020, respectively). In terms of ulcer morphology, patients with DLBCL had significantly higher proportion of deep ulcers than patients with indolent BCL (p = 0.020, respectively). Cox regression analysis showed that drink (p = 0.034), concomitant colonic ulcers (p = 0.034) and elevated LDH (p = 0.043) are risk factors for mortality in patients with PSIL.ConclusionsThis study provides clinical characteristics of patients with PSIL. Thicker intestinal wall and aneurismal dilation detected on CT scan and deeper ulcer on DBE examination helps to establish a diagnosis of DLBCL.

Robotic-assisted surgery for left-sided colon and rectal resections is associated with reduction in the postoperative surgical stress response and improved short-term outcomes: a cohort study.

There is growing evidence that the use of robotic-assisted surgery (RAS) in colorectal cancer resections is associated with improved short-term outcomes when compared to laparoscopic surgery (LS) or open surgery (OS), possibly through a reduced systemic inflammatory response (SIR). Serum C-reactive protein (CRP) is a sensitive SIR biomarker and its utility in the early identification of post-operative complications has been validated in a variety of surgical procedures. There remains a paucity of studies characterising post-operative SIR in RAS. Retrospective study of a prospectively collected database of consecutive patients undergoing OS, LS and RAS for left-sided and rectal cancer in a single high-volume unit. Patient and disease characteristics, post-operative CRP levels, and clinical outcomes were reviewed, and their relationships explored within binary logistic regression and propensity scores matched models. A total of 1031 patients were included (483 OS, 376 LS, and 172 RAS). RAS and LS were associated with lower CRP levels across the first 4 post-operative days (p < 0.001) as well as reduced complications and length of stay compared to OS in unadjusted analyses. In binary logistic regression models, RAS was independently associated with lower CRP levels at Day 3 post-operatively (OR 0.35, 95% CI 0.21-0.59, p < 0.001) and a reduction in the rate of all complications (OR 0.39, 95% CI 0.26-0.56, p < 0.001) and major complications (OR 0.5, 95% CI 0.26-0.95, p = 0.036). Within a propensity scores matched model comparing LS versus RAS specifically, RAS was associated with lower post-operative CRP levels in the first two post-operative days, a lower proportion of patients with a CRP ≥ 150 mg/L at Day 3 (20.9% versus30.5%, p = 0.036) and a lower rate of all complications (34.7% versus 46.7%, p = 0.033). The present observational study shows that an RAS approach was associated with lower postoperative SIR, and a better postoperative complications profile.

Effects of preoperative and postoperative carbohydrate loading on gastrointestinal function and stress-induced inflammation after radical prostatectomy

Background: Early postoperative oral clear liquid diet has been shown to enhance postoperative recovery. However, the standard strategy for this diet has not been established. The authors’ aim was to investigate the combined effect of preoperative and early postoperative carbohydrate loading on postoperative stress and gastrointestinal function of patients by standardizing the starting time, type, volume, and concentration of carbohydrate drinks. Materials and methods: Fifty-three patients undergoing radical prostatectomy were randomly assigned to two groups. Both groups received a carbohydrate loading of 400 ml (12.5%) overnight and 2 h before surgery. The intervention group (n=29) started a 400 ml (12.5%) carbohydrate loading 6 h after surgery and consumed it within 24 h, while the control group (n=32) drank water. The primary outcomes–postoperative fasting blood glucose, fasting insulin, C-reactive protein (CRP), interleukin-6 levels, and gastrointestinal function–were recorded. Secondary outcomes included subjective comfort assessment, the first postoperative intake of semi-fluid food time, and drainage volume. Results: Compared with the control group, the intervention group had lower CRP levels on postoperative day 1 (POD1)/POD2 and less drainage volume on POD1. The intervention group also experienced shorter times to the first postoperative flatus and the first consumption of semi-fluid foods; their 72-h postoperative protein intake was higher than that of the control group. Conclusion: The results suggest that combined preoperative and postoperative carbohydrate loading can alleviate stress-induced inflammation and promote the recovery of postoperative gastrointestinal function.

PREDICTORS OF ATYPICAL CHEST IMAGING IN PATIENTS WITH PULMONARY TUBERCULOSIS

This study aimed to identify the risk factors associated with abnormal chest imaging in patients diagnosed with pulmonary tuberculosis. A retrospective study was conducted between December 2022 and December 2023 in the Radiology Department of Mayo Hospital, Lahore. The study included 100 patients who were diagnosed with smear-positive pulmonary tuberculosis and had undergone chest computed tomography (CT) within two weeks before or after hospital admission. Patients' performance status was assessed on a scale of 0-4. CT scans were performed on all patients, and radiologists were unaware of the patient's data. They examined the scans to determine the presence of lung involvement (upper, middle, and lower) and cavity. Out of 100 patients, 48 (48%) had non-cavity disease. Univariate analysis revealed that patients with non-cavity disease were most likely to be female, older, and have low estimated glomerular filtration rate (eGFR) and C-reactive protein (CRP) levels compared to patients with cavities. In multivariate analysis, low CRP levels were found to be the most potent risk factor for non-cavity disease after adjusting for co-variables. Additionally, 70 patients (70%) presented with non-upper predominant lung disease. Univariate analysis revealed that the majority of patients in this group were women and had high CRP levels, low albumin levels, and poor performance status. Poor performance status was the most potent risk factor for non-upper predominant lung disease. Based on the study findings, low C-reactive protein levels and poor performance status are the most substantial risk factors for non-cavity and non-upper predominant lung disease, respectively, in patients with pulmonary tuberculosis.

Leading determinants of incident dementia among individuals with and without the apolipoprotein E ε4 genotype: a retrospective cohort study

BackgroundLittle is known regarding the leading risk factors for dementia/Alzheimer’s disease (AD) in individuals with and without APOE4. The identification of key risk factors for dementia/Alzheimer’s disease (AD) in individuals with and without the APOE4 gene is of significant importance in global health.MethodsOur analysis included 110,354 APOE4 carriers and 220,708 age- and sex-matched controls aged 40–73 years at baseline (between 2006–2010) from UK Biobank. Incident dementia was ascertained using hospital inpatient, or death records until January 2021. Individuals of non-European ancestry were excluded. Furthermore, individuals without medical record linkage were excluded from the analysis. Moderation analysis was tested for 134 individual factors.ResultsDuring a median follow-up of 11.9 years, 4,764 cases of incident all-cause dementia and 2065 incident AD cases were documented. Hazard ratios (95% CIs) for all-cause dementia and AD associated with APOE4 were 2.70(2.55–2.85) and 3.72(3.40–4.07), respectively. In APOE4 carriers, the leading risk factors for all-cause dementia included low self-rated overall health, low household income, high multimorbidity risk score, long-term illness, high neutrophil percentage, and high nitrogen dioxide air pollution. In non-APOE4 carriers, the leading risk factors included high multimorbidity risk score, low overall self-rated health, low household income, long-term illness, high microalbumin in urine, high neutrophil count, and low greenspace percentage. Population attributable risk for these individual risk factors combined was 65.1%, and 85.8% in APOE4 and non-APOE4 carriers, respectively. For 20 risk factors including multimorbidity risk score, unhealthy lifestyle habits, and particulate matter air pollutants, their associations with incident dementia were stronger in non-APOE4 carriers. For only 2 risk factors (mother’s history of dementia, low C-reactive protein), their associations with incident all-cause dementia were stronger in APOE4 carriers.ConclusionsOur findings provide evidence for personalized preventative approaches to dementia/AD in APOE4 and non-APOE4 carriers. A mother’s history of dementia and low levels of C-reactive protein were more important risk factors of dementia in APOE4 carriers whereas leading risk factors including unhealthy lifestyle habits, multimorbidity risk score, inflammation and immune-related markers were more predictive of dementia in non-APOE4 carriers.

(090) The Relationship Between C-Reactive Protein and Total Testosterone in Aging Men: Findings from the Baltimore Longitudinal Study of Aging

Abstract Introduction Elevated C-Reactive Protein (CRP) and testosterone deficiency are associated with advanced age and chronic inflammatory diseases, such as cancer, diabetes, and cardiovascular disease. Testosterone decreases inflammation through several mechanisms, and testosterone replacement therapy (TRT) has been shown to lower CRP levels in aging, hypogonadal men. While cross-sectional studies have shown an inverse relationship between CRP and total testosterone (TT) levels, mixed findings have been reported when individual components of metabolic syndrome are considered. We hypothesized that men with testosterone deficiency will have high levels of CRP. Objective We evaluated the relationship between CRP and TT levels in men from 2004-2018 using the Baltimore Longitudinal Study of Aging and specifically attempted to determine if low androgen status is associated with a high inflammatory profile independent of comorbidities. Methods Male participants with serum TT level measured during two separate visits &amp;gt;3 years apart were included in our cohort. CRP, High-Density Lipoprotein (HDL) and Triglyceride levels were collected via blood specimens. Comorbidity data were documented at each visit. Panel regression was used to analyze the relationship of a series of independent variables collected in pooled cross-sectional observations over time with a dependent variable for modeling. Results A total of 347 patients were included in this study (mean age = 69 ± 15, average follow up time = 6.7 ± 3.2 years). Participants had a median CRP level of 1.0 mg/dL and a median TT level of 446 ng/dL. On univariable analysis TT and HDL levels were associated with a decline in CRP, while BMI, congestive heart failure (CHF), Diabetes, and Triglycerides were associated with increased CRP. Age was not associated with CRP. On multivariable analysis, we found that increasing TT level was associated with a decline in CRP levels, independent of comorbidities (p = 0.018; Table 1). BMI was associated with a significant increase in CRP (p = 0.001, Table 1). Age, CHF, Diabetes, HDL, and Triglycerides were not significant predictors of CRP on multivariable analysis. Conclusions Lower levels of serum total testosterone are associated with an increased CRP in older men. Given the importance of CRP in pathogenesis of chronic disease, we highlight the potential benefits of restoring testosterone levels in older, hypogonadal men via TRT. Disclosure No.

Evaluation of Oxidative and Nitrosative Stress Markers Related To Inflammation in The Cumulus Cells and Follicular Fluid of Women Undergoing Intracytoplasmic Sperm Injection: A Prospective Study.

Oxidative/nitrosative stress in the oocyte microenvironment could have an impact on intracytoplasmic sperm injection (ICSI) outcomes. The presence of reactive oxygen species (ROS) and reactive nitrogen species (RNS) can stimulate the secretion of pro-inflammatory cytokines, leading to chronic inflammation and potentially affecting embryo as well as oocyte quality. This study aimed to examine the relationship of lipid peroxidation [measured by the malondialdehyde (MDA) assay] with protein carbonyl [measured by the 2,4 dinitrophenylhydrazine (DNPH) assay] levels in cumulus cells (CCs), as well as nitric oxide (NO), peroxynitrite (ONOO-), and C-reactive protein (CRP) levels in follicular fluid (FF). The potential relationship of these levels with ICSI outcome was also evaluated. In this prospective study, 63 FF samples and their corresponding CCs were collected for ICSI procedures. Spectrophotometry was used to assess levels of DNPH, MDA, NO, and ONOO-. CRP levels were evaluated using an immunoturbidimetric assay. The patients under 37 years with normal ovarian reserve had significantly lower levels of MDA, DNPH, NO, ONOO-, and CRP compared to those over 37 years. Additionally, we observed higher levels of MDA, DNPH, NO, ONOO-, and CRP in the group with an oocyte maturity rate of less than 60%. No significant difference was observed between the DNPH levels and factors such as infertility duration, embryo quality, pregnancy, or the number of retrieved oocytes. A higher level of MDA, NO, ONOO-, and CRP was found to be significantly related to the lower number of retrieved oocytes, longer periods of infertility, poor embryo quality, and negative pregnancy outcomes. Oxidative/nitrosative stress, linking to inflammation in the oocyte microenvironment, can be considered as a potentially useful biomarker for assessing the development and competence of oocytes and embryos and predicting ICSI outcomes.

Key differences between chronic inducible and spontaneous urticaria.

The latest international EAACI/GA²LEN/EuroGuiDerm/APAAACI guideline for urticaria recommends limited laboratory testing for chronic spontaneous urticaria (CSU) and selective testing for only certain chronic inducible urticaria (CIndU) subtypes, though the rationale for these recommendations is poorly explained. This study aimed to improve the understanding of CIndU subtypes by comprehensively comparing their demographic, clinical, and laboratory characteristics with those of the better-characterized CSU. We conducted a retrospective analysis of 567 patients (median age 41 years, 67% female) diagnosed with CSU, symptomatic dermographism (SD), cold urticaria (ColdU), cholinergic urticaria (CholU), and delayed pressure urticaria (DPU). Our findings revealed that patients with SD, ColdU, and CholU had lower levels of C-reactive protein (CRP), higher total serum immunoglobulin E (IgE) levels, and higher basophil counts compared to CSU patients. These subtypes also had distinct demographic and clinical features, such as a younger age of onset and a longer disease duration. In contrast, patients with DPU had significantly higher CRP levels and neutrophil counts compared to those with CSU. These findings highlight the heterogeneity among chronic urticaria subtypes, suggesting that a tailored approach to laboratory testing may be more effective. The distinct immunological and clinical features observed in CIndU subtypes suggest a need for subtype-specific diagnostic and therapeutic guidelines.

The impact of inappropriate steroid exposure before the diagnosis of Kawasaki disease

BackgroundKawasaki disease (KD) is a systemic inflammatory disease characterized by vasculitis. In South Korea, some pediatric doctors empirically prescribe steroids to control febrile pediatric patients. This study aimed to evaluate the clinical characteristics of patients with KD after steroid exposure. MethodsThis was a single-center, retrospective, observational study. This study included patients (aged ≤15 years) between January 2020 and July 2022. We compared two groups, one group exposed to steroids and the other group who were not, using the Student's t-test or analysis of variance; otherwise, the Mann–Whitney U test or Kruskal–Wallis test was conducted. Statistical significance was set at p < 0.05. ResultsIn total, 190 patients with KD were enrolled; of these, 64 (33.7 %) had a history of steroid exposure, and 126 (66.3 %) had no history of steroid exposure. In the steroid exposure group, prolonged fever duration (6.72 ± 1.72 versus 5.61 ± 1.19, p-value = <0.001), a lower proportion of complete KD (29.69 % vs. 88.10 %, p-value = <0.001), and a significantly lower level of C-reactive protein were observed. However, no significant correlations were observed between the Transthoracic Echocardiography (TTE) results (coronary artery aneurysm, existence of pericardial effusion) and prognostic factors (days of hospitalization, the number of intravenous immunoglobulin administrations, and Kobayashi score) between the two groups. ConclusionsPatients with KD and previous steroid exposure may exhibit an incomplete KD phenotype with prolonged fever. Although previous steroid exposure does not affect the prognosis of KD, including coronary artery aneurysms, it may mask the classic features of KD, resulting in a delayed diagnosis.

Clinical and prognostic implications of hyaluronic acid in patients with COVID-19 reinfection and first infection.

Previous research has shown that human identical sequences of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) promote coronavirus disease 2019 (COVID-19) progression by upregulating hyaluronic acid (HA). However, the association of HA with mortality and long COVID in SARS-CoV-2 reinfection and first infection is unclear. Patients with COVID-19 at Beijing Ditan Hospital from September 2023 to November 2023 were consecutively enrolled. SARS-CoV-2 reinfections were matched 1:2 with first infections using a nearest neighbor propensity score matching algorithm. We compared the hospital outcomes between patients with COVID-19 reinfection and first infection. The association between HA levels and mortality and long COVID in the matched cohort was analyzed. The reinfection rate among COVID-19 hospitalized patients was 25.4% (62 cases). After propensity score matching, we found that reinfection was associated with a better clinical course and prognosis, including lower levels of C-reactive protein and erythrocyte sedimentation rate, fewer cases of bilateral lung infiltration and respiratory failure, and shorter viral clearance time and duration of symptoms (p < 0.05). HA levels were significantly higher in patients with primary infection [128.0 (90.5, 185.0) vs. 94.5 (62.0, 167.3), p = 0.008], those with prolonged viral clearance time [90.5 (61.5, 130.8) vs. 130.0 (95.0, 188.0), p < 0.001], and deceased patients [105.5 (76.8, 164.5) vs. 188.0 (118.0, 208.0), p = 0.002]. Further analysis showed that HA was an independent predictor of death (AUC: 0.789), and the risk of death increased by 4.435 times (OR = 5.435, 95% CI = 1.205-24.510, p = 0.028) in patients with high HA levels. We found that patients with HA levels above 116 ng/mL had an increased risk of death. However, the incidence of long COVID was similar in the different HA level groups (p > 0.05). Serum HA may serve as a novel biomarker for predicting COVID-19 mortality in patients with SARS-CoV-2 reinfection and first infection. However, HA levels may not be associated with long COVID.

Correlation Between C-Reactive Protein (CRP) Level and Chemotherapy Response in Colorectal Cancer Patients Based on Carcinoembryonic Antigen (CEA) Levels in Post Definitive Operative and Adjuvant Chemotherapy Three Series at Prof. Dr. I.G.N.G Ngoerah Denpasar Hospital

Background: Colorectal cancer is the third leading cause of cancer-related deaths worldwide. Surgical therapy is the primary modality for early-stage cancer with curative goals; chemotherapy is the direct option in advanced cancer with palliative goals; radiotherapy is one of the primary therapy modalities for rectal cancer. The markers for chemotherapy response include CRP and CEA. Elevated CRP and CEA levels in CRC patients are associated with poor chemotherapy response. Objective: to determine the relationship between C-reactive protein (CRP) levels and chemotherapy response measured by Carcinoembryonic Antigen (CEA) levels in colorectal cancer patients at Prof. Dr. IGNG Ngoerah Hospital. Method: analytic observational study with a retrospective cohort study design. The sample in this study used the total consecutive sampling method. The analysis was carried out with the help of SPSS, including descriptive statistical tests, chi-square tests, and correlation tests with Spearman-Rho. Results: 58 patients were divided into 2 groups of 29 each for the group with high CRP levels (≥5 mg/dl) and low CRP levels (&lt;5 mg/dl). The male subjects with the most age &lt;60 years and stage III. Most duration of illness &lt; 2 years. The relationship between CRP levels and chemotherapy response was based on CEA, RR 3.2 [95% CI 1.1-9.6; p 0.030], and the value of the positive correlation coefficient with strong strength is r = 0.722. Conclusion: high CRP levels are significantly associated with a strong correlation to worse chemotherapy response in colorectal cancer patients characterized by a high risk of increasing CEA levels 3.7 times after three series of FOLFIRI adjuvant chemotherapy.

WITHDRAWN: Evaluation of C-reactive protein and its prognostic relationship in patients with Hodgkin's Lymphoma

ObjectivesTo assess the prognostic value of C-Reactive Protein (CRP), at diagnosis and during follow-up, of patients with Hodgkin´s Lymphoma treated at the Hematology Service of the Santa Casa de São Paulo Hospital, and to correlate serum CRP levels with disease stage and treatment response. MethodsA retrospective study involving review of 71 medical records of patients diagnosed with Hodgkin´s Lymphoma between February 2012 and January 2016 was performed. Three patients were subsequently excluded, giving a total of 68 patients for analysis. A level of CRP > 1mg/dl was considered elevated. ResultsPatients were predominantly male (61.8%) and mean age was 34 years. Fifty-three (78%) patients had advanced stage and (76.5%) had B symptoms. Elevated baseline CRP was associated with greater likelihood of B symptoms (p= 0.02) and of advanced stage (p= 0.015). Patients with Low CRP level after 5th and 6th cycles of chemotherapy was associated with complete response (p=0.04 and p=0.03, respectively). Treatment-refractory patients had greater risk of death (p=0.002). ConclusionCRP is clinically important for follow-up of patients with Hodgkin´s Lymphoma, where high levels were associated with advanced disease and/or presence of B symptoms. CRP level was considered a predictor of treatment response. Persistence of high CRP values during treatment was associated with refractoriness.

Comparison of Computed Tomography and Clinical Features Between Patients Infected with the SARS-CoV-2 Omicron Variant and the Original Strain.

To investigate potential differences in clinical and computed tomography (CT) features between patients with the SARS-CoV-2 Omicron variant and the original strain. This retrospective study included 69 hospitalized patients infected with Omicron variant from November to December 2022, and 96 hospitalized patients infected with the original strain from February to March 2020 in Chongqing, China. The clinical features, CT manifestations, degrees of lung involvement in different stages on CT, and imaging changes after the reverse-transcription polymerase chain reaction (RT-PCR) results turned negative were compared between the two groups. For clinical features, patients with Omicron were predominantly old people and females, without manifestation of any clinical symptoms, who had low serum levels of C-reactive protein and procalcitonin. Shorter interval from symptoms onset to initial CT scan was observed in Omicron patients compared to patients with the original strain (all P < 0.05). For CT features, patients with Omicron were more likely to present with round-like opacities and tree-in-bud pattern (all P < 0.05), but less likely to exhibit a diffuse distribution, patchy and linear opacities, as well as vascular enlargement pattern (all P < 0.05). The Omicron group was more susceptible to exhibiting lower CT involvement scores in each stage (all P < 0.05) and imaging progression after the RT-PCR results turned negative (P < 0.001). Patients infected with the Omicron variant exhibited less severe changes on chest CT compared to those infected with the original strain. Furthermore, imaging progression under low viral load conditions was more common in patients with Omicron than in those with the original strain.

Predictive Value of the Neutrophil-to-Lymphocyte Ratio and C-Reactive Protein in Patients with Idiopathic Facial Nerve Palsy.

This study aims to investigate the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) in patients with idiopathic facial nerve palsy. The clinical data of patients with idiopathic facial nerve palsy were retrospectively analyzed. After three months of follow-up, patients were divided into good prognosis and poor prognosis, and the correlation between NLR, CRP and idiopathic facial nerve palsy was analyzed. Negative correlation of NLR with Portmann score in idiopathic facial nerve palsy (r=-0.788, P<0.05); In contrast to the group with poor prognosis, patients in good prognosis group had low levels of body mass index (BMI), NLR, and C-reactive protein (CRP), and high Portmann score (P<0.05); Multivariate logistic regression analysis showed Portmann score (OR=1.268, 95% CI (1.005-1.616)), NLR (OR=0.262, 95% CI (0.128-0.533)) and CRP levels (OR=0.949, 95% CI (0.895-0.989)) were risk factors of poor prognosis for patients with idiopathic facial nerve palsy. The area under the receiver operator characteristic (ROC) curve of NLR and CRP levels in predicting poor facial nerve function was 0.764 and 0.697, the specificity was 85.5% and 75.0%, and the sensitivity was 74. 0% and 76.0%, respectively. The ROC curve of the combined diagnosis was 0.829, the specificity was 80.7%, and the sensitivity was 82.0%. Elevated NLR and CRP are associated with a poor prognosis of idiopathic facial nerve palsy and can serve as an indicator for clinical prognosis, and can be widely used in clinical.
