Clinical and Radiological Predictors of Positive Microbiological Yield in Vertebral Osteomyelitis: A Retrospective Cohort Study

Objective: To evaluate demographic, laboratory, biopsy, and imaging variables as potential predictors of microbial identification in patients with suspected vertebral osteomyelitis, aiming to enhance diagnostic accuracy and optimize patient care. Methods: This retrospective cohort study analyzed 83 patients who underwent image-guided percutaneous disc-space sampling between June 2020 and December 2023. Inclusion criteria were adults aged ≥18 years with imaging-based evidence of vertebral osteomyelitis and clinical suspicion of infection. Exclusion criteria were presence of known malignancy and non-infective causes. Demographics, clinical history, imaging, biopsy, and microbiology data were collected. Logistic regression analysis was used to identify predictors of positive microbiological yield. Results: Microorganisms were identified in 32 of 83 cases (38.6%), with Mycobacterium tuberculosis being the most common pathogen identified (21.9%). Elevated C-reactive protein (CRP) levels, erythrocyte sedimentation rate (ESR), and paravertebral signal changes on MRI were associated with a positive culture yield. Multivariate analysis identified CRP as an independent predictor of positive microbiological results. CT-guided percutaneous biopsy was found to be safe, with no major complications reported. Conclusion: CT-guided percutaneous biopsy is a reliable and safe diagnostic tool for identifying the causative pathogens in vertebral osteomyelitis. Elevated CRP levels were independently associated with positive microbiological yield, highlighting its role as a crucial predictor in clinical practice. These findings underscore the importance of incorporating CRP levels into the diagnostic process, potentially guiding the selection of patients for biopsy to improve the detection of infection.

White blood cell counts, ratios, and C-reactive protein among individuals with schizophrenia spectrum disorder and associations with long-term outcomes: a population-based study

BackgroundImmune mechanisms are associated with adverse outcomes in schizophrenia; however, the predictive value of various peripheral immune biomarkers has not been collectively investigated in a large cohort before. ObjectiveTo investigate how white blood cell (WBC) counts, ratios, and C-Reactive Protein (CRP) levels influence the long-term outcomes of individuals with schizophrenia spectrum disorder (SSD). MethodsWe identified all adults in the Central Denmark Region during 1994–2013 with a measurement of WBC counts and/or CRP at first diagnosis of SSD. WBC ratios were calculated, and both WBC counts and ratios were quartile-categorized (Q4 upper quartile). We followed these individuals from first diagnosis until outcome of interest (death, treatment resistance and psychiatric readmissions), emigration or December 31, 2016, using Cox regression analysis to estimate adjusted hazard ratios (aHRs). ResultsAmong 6,845 participants, 375 (5.5 %) died, 477 (6.9 %) exhibited treatment resistance, and 1470 (21.5 %) were readmitted during follow-up. Elevated baseline levels of leukocytes, neutrophils, monocytes, LLR, NLR, MLR, and CRP increased the risk of death, whereas higher levels of lymphocytes, platelets, and PLR were associated with lower risk. ROC analysis identified CRP as the strongest predictor for mortality (AUC=0.84). Moreover, elevated levels of leukocytes, neutrophils, monocytes, LLR, NLR and MLR were associated with treatment resistance. Lastly, higher platelet counts decreased the risk of psychiatric readmissions, while elevated LLR increased this risk. ConclusionsElevated levels of WBC counts, ratios, and CRP at the initial diagnosis of SSD are associated with mortality, with CRP demonstrating the highest predictive value. Additionally, certain WBC counts and ratios are associated with treatment resistance and psychiatric readmissions.

Impact of Systolic Blood Viscosity on Deep White Matter Hyperintensities in Patients With Acute Ischemic Stroke.

Elevated blood viscosity (BV), a critical determinant in blood rheology, is a contributing factor in cerebrovascular diseases. The specific influence of BV on small vessel disease burden remains unexplored. This study aims to examine the relationship between BV and regional white matter hyperintensity (WMH) volume in patients with acute ischemic stroke. We enrolled a cohort of 302 patients with acute ischemic stroke or transient ischemic attack who were admitted to a hospital within 7 days of symptom onset in this study. We measured whole BV using a scanning capillary-tube viscometer and categorized systolic blood viscosity into 3 groups based on established references. We quantified and normalized WMH volumes using automated localization and segmentation software by NEUROPHET Inc. We performed multivariable logistic regression analysis to assess the correlation between systolic BV and WMH. The mean subject age was 66.7±13.4 years, and 38.7% (n=117) of the participants were female. Among a total of 302 patients, patients with higher deep WMH volume (T3) were typically older and had an atrial fibrillation, strokes of cardioembolic or undetermined cause, elevated levels of C-reactive protein, diastolic blood viscosity and systolic BV. A multivariable adjustment revealed a significant association between high systolic BV and increased deep-WMH volume (odds ratio [OR], 2.636 [95% CI, 1.225-5.673]). Elevated systolic BV is more likely to be associated with deep WMH volume in patients with acute ischemic stroke or transient ischemic attack. These findings reveal novel therapeutic strategies focusing on blood rheology to enhance cerebral microcirculation in stroke management.

Abstract Tu039: Intestinal atrophy contributes to low-grade inflammation, cardiac dysfunction and metabolic syndrome-like phenotype in a model of heart failure with preserved ejection fraction.

Introduction: Heart failure with preserved ejection fraction (HFpEF) comprises half of all HF cases and lacks effective treatment. HFpEF is now seen as a systemic syndrome often linked to comorbidities like hypertension, obesity, and diabetes. These conditions are commonly associated with unhealthy diets rich in fats but lacking in fiber. We explored the effects of a 3-week exposure to excess mineralocorticoids, salt, and high fat diet (HFD) deficient in fiber. We hypothesize that these challenges lead to intestinal atrophy, contributing to low-grade inflammation that promotes the progression of heart failure and metabolic disease. Methods: We used a mix of 1% saline in drinking water and subcutaneous implantation of controlled-release DOCA pellets (0.83 mg/day) alongside a high-fat diet (60% fat) in 8-week-old female and male C57BL6/J mice. Control mice received a standard chow diet and regular water. Results: The challenge resulted in significant reductions in colon mass, colon length, crypt length, and mucus layer thickness compared to the control group. Additionally, elevated levels of C-reactive protein and IL-6 were detected in the plasma. These changes were accompanied by alterations in diastolic function, including decreased peak myocardial relaxation velocity (e'), elevated E/e' ratio, increased E/A ratio, and prolonged isovolumetric relaxation time (IVRT), while the ejection fraction (EF) remained unchanged. Contractility parameters, such as peak myocardial contraction velocity (s'), declined in challenged mice, along with diminished stroke volume (SV). We also found increased organ weight in the liver, spleen, and lungs indicative of organ congestion. Furthermore, signs of metabolic syndrome were identified, including increased body weight, increased adiposity characterized by gonadal and subcutaneous fat accumulation, and dysglycemia (see Data Table). Conclusions: Our data suggests that in this model, heart failure triggers intestinal hypoperfusion, resulting in intestinal atrophy and compromising the integrity of the intestinal lining. Additionally, a diet rich in fat and lacking in fiber alters the gut environment by diminishing mucus production and promoting a closer interaction between the microbiome and host cells. This compromised mucus layer and intestinal barrier facilitates bacterial wall products to move into the circulation, resulting in a pro-inflammatory state that subsequently affects both cardiac function and metabolism.

Risks and benefits of anti-TNF therapy for ulcerative colitis in a patient with autoimmune hepatitis-related cirrhosis: Case report.

Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) characterized by continuous inflammation of the colonic mucosa. Autoimmune hepatitis (AIH) is a chronic liver disease characterized by hypergammaglobulinemia, circulating autoantibodies, interface hepatitis, and favorable response to immunosuppression. An association between IBD and AIH is uncommon, and experts have suggested that in patients with overlapping IBD and AIH, the anti-tumor necrosis factor agents can be used. Therefore, this study reports a rare case of a patient with liver cirrhosis due to AIH and UC refractory to conventional treatment and discusses the risks and benefits of using anti-tumor necrosis factor in both conditions. A 28-year-old female presented with symptoms of diarrhea, abdominal pain, asthenia, and inappetence, accompanied by abdominal collateral circulation, anemia, alteration of liver enzymes, and elevation of C-reactive protein levels. The patient underwent a liver biopsy, which was consistent with liver cirrhosis due to AIH. Colonoscopy showed an inflammatory process throughout the colon, compatible with moderately active UC. The patient received mesalazine, azathioprine, and corticotherapy, with no control of the inflammatory process. Faced with refractoriness to drug treatment and side effects of corticosteroids with an increased risk of severe infection due to cirrhosis, we opted to use infliximab for the treatment of UC. The patient presented with a clinical response and infliximab therapy was maintained. Eight months after starting infliximab therapy, the patient developed pneumonia with complications from disseminated intravascular coagulation and died. AIH is a rare cause of elevated transaminase levels in patients with UC. The best treatment to control the 2 conditions should be evaluated with vigilance for the side effects of medications, mainly infections, especially in patients with cirrhosis.

Prediction of Clinical Severity of COVID-19 Using a Combination of Heparin-Binding Protein, Interleukin-6, and C-Reactive Protein: A Retrospective Study.

Systemic inflammation stands as a pivotal factor tightly interwoven with the progression of COVID-19. This study endeavors to elucidate the significance of three key inflammatory molecules, that is, heparin-binding protein (HBP), interleukin-6 (IL-6), and C-reactive protein (CRP), in assessing the severity and prognostic implications of COVID-19. The demographic, clinical, and laboratory data were retrospectively collected from a cohort of 214 adult patients diagnosed with COVID-19. Patients were divided into two groups: nonsevere (n = 93; 43.5%) and severe (n = 121; 56.5%). Additionally, based on their organ function, patients were categorized into nonorgan failure (n = 137) and organ failure (n = 77) groups. The levels of inflammation-related cytokines were then compared among these defined groups. The severe group was characterized by a higher proportion of males, older age, and longer hospital stays compared to nonsevere cases. Additionally, severe cases exhibited a higher prevalence of underlying diseases and organ failure. Statistical analysis revealed significantly elevated levels of HBP, IL-6, and CRP in the severe group. HBP, IL-6, and CRP were identified as independent risk factors for severe COVID-19. Furthermore, a combined assessment of these biomarkers demonstrated superior diagnostic sensitivity (85.10%) and specificity (95.70%) for predicting COVID-19 severity. A positive relationship between elevated HBP, IL-6, and CRP levels and impaired organ function was also observed. The predictive efficiency significantly increased (hazard ratio = 3.631, log-rank p = 0.003) when two or more of them were combinedly used. Notably, elevated levels of HBP, IL-6, and CRP were associated with an increased risk of mortality. In conclusion, the combined assessment of HBP, IL-6, and CRP offers enhanced accuracy and specificity in predicting the severity, organ failure, and mortality risk associated with COVID-19.

Study of C-reactive Protein Levels in Hypertensive Disorders of Pregnancy.

Introduction Globally, one of the main causes of maternal and perinatal deaths is hypertensive disorders of pregnancy (HDP). Preeclampsia is a pregnancy-specific syndrome characterized by high blood pressure and proteinuria after 20-week gestation. Women who develop preeclampsia are at increased risk for the development of many systemic complications. Materialsandmethods A cross-sectional study was conducted in the Department of Biochemistry, SHKM, Nuh, Haryana in collaboration with the Department of Obstetrics & Gynecology. 200 study subjects; Group 1: cases - 100 HDP, Group 2: controls - 100 age-matched normotensive pregnant women. The specimen of 3 mL venous blood was collected under aseptic precautions. The data was evaluated using statistical evaluation tools. Result Out of 200 subjects, mean C-reactive protein (CRP) levels were normal in three cases and 35 controls. Minor elevation of CRP was observed in 11 cases and 29 controls (very significant). Moderate elevation of CRP was observed in 61 cases and 36 controls (highly significant). Marked elevation of CRP was observed in 25 cases. Mean CRP levels increased from preeclampsia without severe features (3.9 mg/dL), preeclampsia with severe features (5.2 mg/dL), and eclampsia (12.7 mg/dL) when compared with the respective control group (1.1 mg/dL, 1.16 mg/dL, and 1.2 mg/dL). Conclusion There is a highly significant association between CRP levels and HDP. Additionally, one useful indicator of the severity of preeclampsia is CRP, a measure ofsystemic inflammation. Elevated CRP levels in mild PE can be used as an indicator of the progress of the disease and early prevention can be done.

Assessment of systemic immune-inflammatory index and other inflammatory parameters in predicting mortality in patients with acute cholecystitis: A retrospective observational study

Objective: To investigate the effectiveness of the systemic immune- inflammatory (SII) index and other inflammatory parameters in predicting mortality among patients with acute cholecystitis (AC). Methods: 279 Patients presented to the emergency department with abdominal pain and diagnosis of AC between September 2021 and September 2023 were included in the study. Demographic data, laboratory parameters, clinical follow-ups, and outcomes of the patients were recorded. Results: The mean age of the patients was (55.0±16.3) years and 36.6% were male. 63.8% Had gallbladder/choledochal stones and 49.5% underwent surgery. The mortality rate was 6.1%. Advanced age (P=0.170) and prolonged hospitalization (P=0.011) were statistically significant risk factors for mortality. Decreased lymphocyte count (P=0.020) and increased C-reactive protein (CRP) levels (P=0.033) were found to be risk factors for mortality. According to the mortality predictor ROC analysis results, the cut-off for SII index was 3 138 (AUC=0.817, sensitivity=70.5%, specificity=84.7%), the cut-off for neutrophil count was 15.28×103/ mm3 (AUC=0.761, sensitivity=52.9%, specificity=95.0%), the cut-off for leukocyte count was 19.0×103/mm3 (AUC= 0.714, sensitivity=52.9%, specificity=98.0%), cut-off for CRP was 74.55 (AUC=0.758, sensitivity=70.5%, specificity=79.0%), cut-off for aspartate transaminase (AST) was 33.0 IU/L (AUC=0.658, sensitivity=82.3%, specificity=50.3%). Conclusions: The SII index may be a good predictor of mortality with high sensitivity and specificity. Elevated levels of neutrophils, leukocytes, CRP, and AST are other inflammatory parameters that can be used to predict mortality associated with AC.

Study of Biochemical Predictors of Early Neurological Deterioration in Ischemic Stroke in a Tertiary Care Hospital.

Background and objective Early neurological deterioration (END) following acute ischemic stroke (AIS) poses a significant clinical challenge, often leading to increased disability and mortality. This study aimed to investigate the association between specific biomarkers (lactate dehydrogenase (LDH), ferritin,erythrocyte sedimentation rate (ESR),C-reactive protein (CRP), homocysteine) and the occurrence of END in ischemic stroke patients in a tertiary care hospital. Materials and methods Across-sectional hospital-basedstudy was conducted at Dr. D. Y. Patil Medical College and Hospital, Pune, from July 2022 to April 2024. Patients aged 18 and above with confirmed ischemic stroke were included, while those with hemorrhagic stroke, intracranial tumors, mass effect with midline shift, or extensive cerebral edema were excluded. Upon admission, patients were assessed using the National Institutes of Health Stroke Scale (NIHSS) and monitored daily for seven days. Biomarkers, including LDH, ferritin, ESR, CRP, and homocysteine, were measured, and patients were categorized into those with END and without END. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 20 (Released 2011; IBM Corp., Armonk, New York). Results Out of 100 patients, 12% experienced END. The mean age of patients with END was 53.50 ± 11.20 years, compared to 53.62 ± 11.74 years in those without END (p = 0.790). Males constituted 91.7% of the END group and 73.9% of the non-END group (p = 0.284). A significant association was found between END and alcohol use (41.7% in END vs. 12.5% in non-END, p = 0.010) and tobacco use (41.7% in END vs. 11.4% in non-END, p = 0.010). The mean NIHSS scores were significantly higher in the END group on day 1 (11.58 ± 3.06 vs. 7.69 ± 3.98,p = 0.002) and on day 3 (13.92 ± 3.15 vs. 6.00 ± 3.65, p = 0.001). Biomarker analysis showed a significant difference in the mean vitamin B12 levels between END and non-END groups (93.17 ± 48.58 vs. 183.45 ± 349.33, p = 0.025). Conclusion Our study identified significant predictors of ENDin ischemic stroke patients, including alcohol and tobacco use, higher initial NIHSS scores, and elevated levels of LDH, ferritin, ESR, CRP, and homocysteine, along with low vitamin B12 levels. These findings highlight the importance of routine biochemical assessments and personalized treatment plans in managing AIS, emphasizing lifestyle changes and nutritional support to improve outcomes. Limitations include the single-center design, small sample size, and lack of long-term follow-up data. Future research should validate these findings in larger, multicenter studies and explore their long-term impact on stroke recovery.

Extended survival of 9- and 10-gene-edited pig heart xenografts with ischemia minimization and CD154 costimulation blockade-based immunosuppression

BackgroundXenotransplantation has made significant advances recently using pigs genetically engineered to remove carbohydrate antigens, either alone or with addition of various human complement, coagulation, and anti-inflammatory ‘transgenes’. Here we evaluated results associated with gene-edited (GE) pig hearts transplanted in baboons using an established costimulation-based immunosuppressive regimen and a cold-perfused graft preservation technique. MethodsEight baboons received heterotopic abdominal heart transplants from 3-GE (GalKO.β4GalNT2KO.hCD55, n=3), 9-GE (GalKO.β4GalNT2KO.GHRKO.hCD46.hCD55. TBM.EPCR.hCD47.HO-1, n=3) or 10-G (9-GE+CMAHKO, n=2) pigs using Steen’s cold continuous perfusion for ischemia minimization. Immunosuppression (IS) included induction with anti-thymocyte globulin and αCD20, ongoing αCD154, MMF, and tapered corticosteroid. ResultsAll three 3-GE grafts functioned well initially, but failed within 5 days. One 9-GE graft was lost intraoperatively due to a technical issue and another was lost at POD 13 due to antibody mediated rejection (AMR) in a baboon with a strongly positive pre-operative cross-match. One 10-GE heart failed at POD113 with combined cellular and antibody mediated rejection. One 9-GE and one 10-GE hearts had preserved graft function with normal myocardium on protocol biopsies, but exhibited slowly progressive graft hypertrophy until elective necropsy at POD393 and 243 respectively. Elevated levels of IL-6, MCP-1, C-reactive protein, and human thrombomodulin were variably associated with conditioning, the transplant procedure, and clinically significant postoperative events. ConclusionRelative to reference genetics without thrombo-regulatory and anti-inflammatory gene expression, 9- or 10-GE pig hearts exhibit promising performance in the context of a clinically applicable regimen including ischemia minimization and αCD154-based IS, justifying further evaluation in an orthotopic model.

Social impact of brain fog and analysis of risk factors: Long COVID in Japanese population.

To reveal the clinical features and assess risk factors linked to brain fog and its societal implications, including labor productivity, providing valuable insights for the future care of individuals who have experienced coronavirus disease 2019 (COVID-19). We analyzed a comprehensive cohort dataset comprising 1,009 patients with COVID-19 admitted to Japanese hospitals. To assess brain fog, we analyzed patients who responded to a questionnaire indicating symptoms such as memory impairment and poor concentration. The prevalence of brain fog symptoms decreased 3 months posthospitalization but remained stable up to 12 months. Neurological symptoms such as taste and smell disorders and numbness at hospitalization correlated with a higher frequency of identifying brain fog as a long COVID manifestation. Our findings indicated that advanced age, female sex, a high body mass index, oxygen required during hospitalization, chronic obstructive pulmonary disease, asthma, and elevated C-reactive protein and elevated D-dimer levels were risk factors in patients exhibiting brain fog. Additionally, we demonstrated the negative impact of brain fog on labor productivity by presenteeism scores. This study clarified the clinical characteristics of patients experiencing brain fog as a long COVID manifestation, specifically emphasizing neurological symptoms during hospitalization and their correlation with brain fog. Additionally, the study identified associated risk factors for its onset and revealed that the emergence of brain fog was linked to a decline in labor productivity.

Multiple infections secondary to immunosuppression after Chlamydia psittaci infection: a case report

This study presents the clinical profile of a 74-year-old male patient admitted to the hospital due to a 20-day history of coughing, chest tightness, and dyspnea. Upon admission, the patient presented with fever, tachycardia, and tachypnea. Clinical examination revealed evidence of lung infection, sepsis, and multi-organ dysfunction, alongside abnormal blood gas analysis and elevated C-reactive protein (CRP) levels. Pathogen testing confirmed Chlamydia psittaci (C. psittaci), infection. Throughout the treatment course, the patient developed concurrent fungal and viral infections, necessitating a comprehensive approach involving combined antibiotic and antifungal therapy. Despite encountering treatment-related complications, the patient demonstrated clinical improvement with aggressive management. This case underscores the importance of recognizing immune suppression subsequent to Chlamydia infection, emphasizing the critical role of early diagnosis, intervention, and standardized treatment protocols in enhancing patient prognosis.

Introducing MCC-PS: a novel prognostic score for Merkel cell carcinoma.

Merkel cell carcinoma (MCC) is an aggressive skin cancer with a poor prognosis, which only improved with the introduction of immunotherapies. An MCC prediction model with high diagnostic accuracy is lacking. The aim was to develop an MCC prognostic score (MCC-PS) based on combinations of previously proposed risk factors. A multicentric, retrospective study was conducted to develop MCC-PS, which included age, neuron-specific enolase (NSE), C-reactive protein (CRP), creatinine, bilirubin, and international normalized ratio (INR). Creatinine, bilirubin, and INR were used to calculate the model of end-stage liver disease (MELD) score. A total of 98 patients were included in the study, including 36.7% with stage I according to American Joint Committee on Cancer 2018 (n = 36), 30.6% with stage II (n = 30), 25.5% with stage III (n = 25), and 7.1% with stage IV (n = 7). Survival data of MCC patients were correlated with selected laboratory parameters and risk factors. Primary endpoint was MCC-specific survival (MSS) and the secondary endpoint was progression-free survival. Several statistical methods were used to develop the prognostic score, including correlation analysis, Kaplan-Meier curves, Cox regression, and time-dependent receiver operating characteristic analysis. The MCC-PS is based on the sum of the following baseline variables: elevated CRP (≥5.5 mg/l), elevated NSE (≥22.8 µg/l), MELD score ≥ 11, and age ≥ 75 years. An MELD score ≥ 11 was scored as 4 points, elevated NSE level as 3 points, elevated CRP level as 2 points, and age ≥ 75 years as 1 point. A high-risk group according to the MCC-PS was characterized by a score of 4 or more points. The high-risk group was associated with a worse prognosis than the low-risk group (1-year MSS 62%, 2-year 43.1%, 5-year 17.6% as compared to 1-year MSS 79.5%, 3-year 75%, 5-year 72%). Notably, the developed MCC-PS predicts MCC outcome measures with high accuracy (3-year MSS: area under the curve (AUC) 0.934, sensitivity 87.5% and specificity 82.2%; 5-year MSS: AUC 0.93, sensitivity 89% and specificity 82%). MCC-PS is the first prognostic score predicting MCC outcome with a high accuracy based on five easily available laboratory parameters and patient's age. An MCC-PS of 4 or more indicates a high-risk patient associated with a poor prognosis.

Medicinal Plant Extracts against Cardiometabolic Risk Factors Associated with Obesity: Molecular Mechanisms and Therapeutic Targets.

Obesity has increasingly become a worldwide epidemic, as demonstrated by epidemiological and clinical studies. Obesity may lead to the development of a broad spectrum of cardiovascular diseases (CVDs), such as coronary heart disease, hypertension, heart failure, cerebrovascular disease, atrial fibrillation, ventricular arrhythmias, and sudden cardiac death. In addition to hypertension, there are other cardiometabolic risk factors (CRFs) such as visceral adiposity, dyslipidemia, insulin resistance, diabetes, elevated levels of fibrinogen and C-reactive protein, and others, all of which increase the risk of CVD events. The mechanisms involved between obesity and CVD mainly include insulin resistance, oxidative stress, inflammation, and adipokine dysregulation, which cause maladaptive structural and functional alterations of the heart, particularly left-ventricular remodeling and diastolic dysfunction. Natural products of plants provide a diversity of nutrients and different bioactive compounds, including phenolics, flavonoids, terpenoids, carotenoids, anthocyanins, vitamins, minerals, fibers, and others, which possess a wide range of biological activities including antihypertensive, antilipidemic, antidiabetic, and other activities, thus conferring cardiometabolic benefits. In this review, we discuss the main therapeutic interventions using extracts from herbs and plants in preclinical and clinical trials with protective properties targeting CRFs. Molecular mechanisms and therapeutic targets of herb and plant extracts for the prevention and treatment of CRFs are also reviewed.

Prognostic value of C-reactive protein in patients with glioma: a meta-analysis.

Background: In this meta-analysis, we investigated C-reactive protein (CRP)'s role in glioma prognosis prediction.Methods: We conducted the current meta-analysis in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for systematic reviews and meta-analyses. An analysis of the prognostic effect of CRP on glioma was conducted using combined hazard ratios (HRs) and 95% confidence intervals (CIs).Results: The combined data suggested that a higher CRP level was markedly related to poor overall survival in glioma (hazard ratio: 1.73; 95% CI: 1.22-2.46; p=0.002).Conclusion: According to results in the present meta-analysis, elevated CRP levels were significantly related to inferior overall survival in glioma.

Research on cognitive impairment and potential risk factors in peritoneal dialysis patients: An observational study.

The objective of this study is to investigate the associated risk factors and their effects on cognitive impairment (CI) in patients undergoing peritoneal dialysis. A retrospective analysis was conducted on the basic information of 268 patients who underwent continuous ambulatory peritoneal dialysis (CAPD) at our hospital from January 2020 to September 2023. Cognitive function was assessed using the Montreal Cognitive Assessment Scale during their subsequent dialysis visits. Participants were categorized into a CI group and a cognitively normal group. Blood and other biological samples were collected for relevant biomarker analysis. Subsequently, we analyzed and compared the factors influencing CI between the 2 groups. The prevalence of CI among CAPD patients was 58.2%. Compared to the cognitively normal group, the CI group had a higher prevalence of alcohol consumption, lower levels of education, and reduced serum uric acid levels (P < .05). There was also a higher incidence of autoimmune diseases such as systemic lupus erythematosus in the CI group (P < .05). In terms of dialysis efficacy, the residual kidney Kt/V and residual kidney Ccr were significantly lower in the CI group compared to the cognitively normal group. In blood parameters, the CI group showed elevated total cholesterol levels and lower serum calcium concentrations (P < .05). Logistic regression analysis identified male gender, older age, lower educational attainment, hypercholesterolemia, and elevated high-sensitivity C-reactive protein levels as independent risk factors for CI in CAPD patients (P < .05). Additionally, in this patient cohort, dialysis duration and residual renal function were protective factors against CI (P < .05). CI is prevalent among PD patients. Elevated high-sensitivity C-reactive protein levels, male gender, older age, lower educational attainment, and hypercholesterolemia constitute an independent risk factor for CI in CAPD patients, whereas residual renal function acts as a protective element.

Development of a Predictive Nomogram for Sepsis in Patients with Urolithiasis-Related Obstructive Pyelonephritis.

Background and Objectives: In patients with urolithiasis-related obstructive pyelonephritis (UROP), sepsis represents a critical and concerning complication that can substantially increase the mortality rate. This study aimed to identify the risk factors for sepsis in UROP patients and to develop a predictive nomogram model. Materials and Methods: We analyzed data from 148 patients who met the UROP criteria and were admitted to Chang Gung Memorial Hospital between 1 January 2016 and 31 December 2021. The primary outcome evaluated was the incidence of sepsis, as defined by the most recent Sepsis-3 guidelines. To identify potential risk factors for sepsis, we employed the Least Absolute Shrinkage and Selection Operator (LASSO) regression technique. Subsequently, we utilized multivariable logistic regression to construct the predictive model. Results: There was a total of 102 non-sepsis cases and 46 sepsis cases. Risk factors for sepsis in multivariable analysis were a history of diabetes mellitus (DM) (OR = 4.24, p = 0.007), shock index (SI) (×10-1) (OR = 1.55, p < 0.001), C-reactive protein (CRP) (mg/dL) (OR = 1.08, p = 0.005), and neutrophil to lymphocyte ratio (NLR) (×10) (OR = 1.58, p = 0.007). The nomogram exhibited an area under the receiver operating characteristic curve of 0.890 (95% CI 0.830-0.949). Conclusions: Our study demonstrated that patients with UROP who have DM, higher SI, higher NLR, and elevated CRP levels are significantly more likely to develop sepsis. These insights may aid in risk stratification, and it is imperative that clinicians promptly initiate treatment for those identified as high risk.

Terminal Ileitis as the Exclusive Manifestation of COVID-19 in Children.

The clinical presentation, organ involvement, and severity of disease caused by SARS-CoV-2 are highly variable, ranging from asymptomatic or mild infection to respiratory or multi-organ failure and, in children and young adults, the life-threatening multisystemic inflammatory disease (MIS-C). SARS-CoV-2 enters cells via the angiotensin-converting enzyme-2 receptor (ACE-2), which is expressed on the cell surfaces of all organ systems, including the gastrointestinal tract. GI manifestations have a high prevalence in children with COVID-19. However, isolated terminal ileitis without other manifestations of COVID-19 is rare. In March 2023, two previously healthy boys (aged 16 months and 9 years) without respiratory symptoms presented with fever and diarrhea, elevated C-reactive protein levels, and low procalcitonin levels. Imaging studies revealed marked terminal ileitis in both cases. SARS-CoV-2 (Omicron XBB.1.9 and XBB.1.5 variants) was detected by nucleic acid amplification in throat and stool samples. Both patients recovered fast with supportive measures only. A differential diagnosis of acute abdominal pain includes enterocolitis, mesenteric lymphadenitis, appendicitis, and more. During SARS-CoV-2 epidemics, this virus alone may be responsible for inflammation of the terminal ileum, as demonstrated. Coinfection with Campylobacter jejuni in one of our patients demonstrates the importance of a complete microbiological workup.

Prognostic value of laboratory markers in patients with acute pulmonary embolism

BackgroundAcute pulmonary embolism (APE) is a serious illness. Identifying prognostic factors for APE may help in the management of those patients. This study’s objective was to evaluate the prognostic value of laboratory markers in predicting right ventricular dysfunction (RVD) and 30-day mortality in pulmonary embolism patients.MethodsEighty patients with APE were enrolled and followed up for 30 days. Detailed echocardiography was done to evaluate RVD. All patients were subjected to arterial blood gas analysis, complete blood count (CBC), plasma concentration of C-reactive protein (CRP), serum D-dimer level, and serum troponin I level, and the following ratio were calculated: neutrophil-to-lymphocytic ratio (NLR), platelet to lymphocytic ratio (PLR), red cell distribution width (RDW), mean platelet volume (MPV), and alveolar to arterial gradient.ResultsOur results analysis revealed significantly elevated levels of median NLR, PLR, CRP, D-dimer, and troponin in both the RVD and non-survivor groups (P value < 0.001). The blood markers that showed the highest predictive ability for right ventricular dysfunction (RVD) and 30-day mortality, as determined by receiver operating characteristic (ROC) analysis and logistic regression, were A-a O2 gradient, serum troponin, CRP, D-dimer, NLR, and PLR (P value < 0.001).ConclusionEvaluation of different serum markers including NLR, PLR, RDW, CRP, D-dimer, troponin, and A-a O2 gradient is a simple and available marker for predicting right ventricular dysfunction (RVD) and 30-day mortality in patients with APE.Trial registrationClinicalTrials.gov ID: NCT04237974.
