The purpose of this study was to observe the time course of muscle damage and inflammatory responses following an eccentric overload resistance-training (EO) program. 3 females (23.8 ± 2.6 years; 70.9 ± 12.7 kg; 1.6 ± 0.08 m) and 5 males (23.8 ± 2.6 years; 75.1 ± 11.2 kg; 1.8 ± 0.1 m) underwent thirteen training sessions (4 × 8–10 eccentric-only repetitions—80% of eccentric 1RM, one-minute rest, 2x week−1, during 7 weeks, for three exercises). Blood samples were collected prior to (Pre) and after two (P2), seven (P7), nine (P9), eleven (P11), and thirteen (P13) sessions, always 96 hours after last session. The reference change values (RCV) analysis was employed for comparing the responses, and the percentual differences between the serial results were calculated for each subject and compared with RCV95%. Four subjects presented significant changes for creatine kinase at P2, and another two at P13; six for C-reactive protein at P2, and three at P11; two for neutrophils at P2, P4, and P13, respectively; and only one for white blood cells at P2, P4, P7, and P9, for lymphocyte at P7, P9, and P13, and for platelet at P4. We conclude that EO induced high magnitude of muscle damage and inflammatory responses in the initial phase of the program with subsequent attenuation.

Background:: Ursolic Acid (UA) is a pentacyclic triterpenoid carboxylic acid which is extracted from plants. UA may enhance the effect of Resistance Training (RT) in human. Objective: Current research was designed to show the effect of High-Intensity Resistance Training (HIRT) in the presence or absence of UA on the serum levels of irisin, CRP, IL-6 and TNF-α in the low activity men. Method:: The study included twenty-two healthy male HIRT with placebo, supplementation, and HIRT in the presence of UA supplementation. The two groups received eight-week intervention including 2 sets of 8 exercises, with 8~10 repetitions at 70~75% of 1 repetition maximum and a 2 min rest interval between sets, performed 3 times/week. Placebo or UA orally was evaluated as 1 capsule 3 times/day during 8 weeks. The subsequent factors were measured post- and preintervention: C-Reactive Protein (CRP), Irisin, Tumor Necrotic Factor (TNF-α) and Interleukin-6 (IL-6). Results:: UA supplementation significantly increased the plasma levels of irisin in the HIRT+UA group versus the HIRT+P group (p<0.05). UA treatment also dramatically decreased the plasma levels of CRP, IL-6, and TNF-α in the HIRT+UA group versus the HIRT+P group (p<0.05). Conclusion:: The current data showed that UA-induced an increase in serum irisin and reduction of CRP, IL-6, and TNF-α may have beneficial effects as a chemical for increasing of the effects of HIRT in low activity men.

The purpose of this study was to determine whether endurance (E) or endurance + resistance (ER) training affects C-reactive protein (CRP) and if these changes are related to alterations in fitness and (or) body composition in young females. Thirty-eight females (aged 18–24 years) were assigned to 1 of 3 groups: (1) E, (2) ER or (3) active control (AC). The E and ER groups completed 15 weeks of marathon training. The ER group performed additional resistance training and the AC group maintained their usual exercise routine. Primary outcomes were measured pre- and post-training and included anthropometric indices, dual-energy x-ray absorptiometry, plasma CRP, time to complete 1.5 miles (in minutes), and upper and lower body strength tests (i.e., 8 repetition max on bench and leg press (ER group only)). There were no differences in any variable among the groups at baseline. After training, the E group decreased time to complete 1.5 miles (p < 0.05). The AC group decreased percent and absolute body fat while the E group decreased percent body fat, absolute body fat, and android and gynoid body fat (p < 0.05). The ER group significantly improved strength (p < 0.001) and reduced plasma CRP from 2.0 ± 1.1 to 0.8 ± 0.3 mg·L–1 (p = 0.03). No significant associations were observed between CRP and measures of body composition or aerobic capacity. Combined endurance and resistance training may be an effective modality for reducing plasma CRP in young adult females independent of changes in aerobic capacity or body composition.

AbstractThe added value of biomarkers, such as procalcitonin (PCT), C-reactive protein (CRP), and white blood cells (WBC), as adjuncts to clinical risk scores for predicting the outcome of patients with community-acquired pneumonia (CAP) is in question. We investigated the prognostic accuracy of initial and follow-up levels of inflammatory biomarkers in predicting death and adverse clinical outcomes in a large and well-defined cohort of CAP patients.We measured PCT, CRP and WBC on days 1, 3, 5, and 7 and followed the patients over 30 days. We applied multivariate regression models and area under the curve (AUC) to investigate associations between these biomarkers, the clinical risk score CURB-65, and clinical outcomes [i.e., death and intensive care unit (ICU) admission].Of 925 patients with CAP, 50 patients died and 118 patients had an adverse clinical outcome. None of the initial biomarker levels significantly improved the CURB-65 score for mortality prediction. Follow-up biomarker levels showed significant independent association with mortality at days 3, 5, and 7 and with improvements in AUC. Initial PCT and CRP levels were independent prognostic predictors of adverse clinical outcome, and levels of all biomarkers during the course of disease provided additional prognostic information.This study provides robust insights into the added prognostic value of inflammatory markers in CAP. Procalcitonin, CRP, and to a lesser degree WBC provided some prognostic information on CAP outcomes, particularly when considering their kinetics at days 5 and 7 and when looking at adverse clinical outcomes instead of mortality alone.

Primary arthritis of chondrosternal joint is very rare and occurs in infants less than 18 months of age. Presentation is most often subacute but may be acute. Child presents with a parasternal mass with history of fever and/or local signs of infection. Clinical symptoms vary from a painless noninflammatory to a painful mass with local tenderness and swelling, while fever may be absent. Laboratory data show low or marginally raised levels of white blood cells and C-reactive protein, reflecting, respectively, the subacute or acute character of the infection. It is a self-limiting affection due to the adequate immune response of the patient. Evolution is generally good without antibiotherapy with a progressive spontaneous healing. A wait-and-see approach with close follow-up in the first weeks is the best therapeutic option.

Abstract BACKGROUND: There remains a proportion of patients with unfavorable outcomes after aneurysmal subarachnoid hemorrhage, of particular relevance in those who present with a good clinical grade. A forewarning of those at risk provides an opportunity towards more intensive monitoring, investigation, and prophylactic treatment prior to the clinical manifestation of advancing cerebral injury. OBJECTIVE: To assess whether biochemical markers sampled in the first days after the initial hemorrhage can predict poor outcome. METHODS: All patients recruited to the multicenter Simvastatin in Aneurysmal Hemorrhage Trial (STASH) were included. Baseline biochemical profiles were taken between time of ictus and day 4 post ictus. The t-test compared outcomes, and a backwards stepwise binary logistic regression was used to determine the factors providing independent prediction of an unfavorable outcome. RESULTS: Baseline biochemical data were obtained in approximately 91% of cases from 803 patients. On admission, 73% of patients were good grade (World Federation of Neurological Surgeons grades 1 or 2); however, 84% had a Fisher grade 3 or 4 on computed tomographic scan. For patients presenting with good grade on admission, higher levels of C-reactive protein, glucose, and white blood cells and lower levels of hematocrit, albumin, and hemoglobin were associated with poor outcome at discharge. C-reactive protein was found to be an independent predictor of outcome for patients presenting in good grade. CONCLUSION: Early recording of C-reactive protein may prove useful in detecting those good grade patients who are at greater risk of clinical deterioration and poor outcome.

Abstract Background Coronavirus disease has heterogeneous clinical features; however, the reasons for the heterogeneity are poorly understood. This study aimed to identify clinical phenotypes according to patients’ temperature trajectory. Method A retrospective review was conducted in five tertiary hospitals in Hubei Province from November 2019 to March 2020. We explored potential temperature-based trajectory phenotypes and assessed patients’ clinical outcomes, inflammatory response, and response to immunotherapy according to phenotypes. Results A total of 1580 patients were included. Four temperature-based trajectory phenotypes were identified: normothermic (Phenotype 1); fever, rapid defervescence (Phenotype 2); gradual fever onset (Phenotype 3); and fever, slow defervescence (Phenotype 4). Compared with Phenotypes 1 and 2, Phenotypes 3 and 4 had a significantly higher C-reactive protein level and neutrophil count and a significantly lower lymphocyte count. After adjusting for confounders, Phenotypes 3 and 4 had higher in-hospital mortality (adjusted odds ratio and 95% confidence interval 2.1, 1.1–4.0; and 3.3, 1.4–8.2, respectively), while Phenotype 2 had similar mortality, compared with Phenotype 1. Corticosteroid use was associated with significantly higher in-hospital mortality in Phenotypes 1 and 2, but not in Phenotypes 3 or 4 (p for interaction < 0.01). A similar trend was observed for gamma-globulin. Conclusions Patients with different temperature-trajectory phenotypes had different inflammatory responses, clinical outcomes, and responses to corticosteroid therapy.

Abstract Background: Systemic inflammatory response and nutritional status are closely related to tumor development, and both have been recognized as predictors of tumors. Our study investigated the effect on the prognosis of osteosarcoma by analyzing the ratio of lymphocytes to C-reactive protein (LCR) before surgery.Methods: Patients who were diagnosed with osteosarcoma and underwent surgery in the First Affiliated Hospital of Guangxi Medical University from 2012 to 2019 were included in this retrospective study. The albumin (g/L) +5 × total lymphocyte count (PNI), neutrophil/lymphocyte count (NLR), platelet/lymphocyte count (PLR) and platelet × neutrophil/lymphocyte count (SII) were calculated from preoperative peripheral white blood cells, C-reactive protein and serum albumin. The optimal cutoff values of LCR, PNI, NLR, PLR and SII were determined by receiver operating characteristic (ROC) analysis. According to the Optimal cutoff values, LCR, PNI, NLR, PLR and SII were divided into high and low groups. The Kaplan-Meier method was used to compare the overall survival (OS) between the high and low LCR groups. Univariate analysis was used to determine the influence of age, gender, tumor size, Enneking stage and neoadjuvant chemotherapy on the prognosis of osteosarcoma.The independent predictors of OS were determined by Cox multivariate analysis.Results: The optimal cutoff values for LCR, PNI, NLR, PLR and SII were 0.093, 48.4, 1.23, 157.03 and 314.27, respectively. A low preoperative LCR was significantly correlated with tumor metastasis, stage, NLR, PLR and SII. However, a low preoperative PNI was significantly associated with tumor metastasis, stage, and PLR.Kaplan-Meier survival analysis indicated that the postoperative OS was significantly correlated with preoperative LCR and PNI (P < 0.05). Univariate analysis showed that Enneking stage, metastasis and preoperative LCR, PNI, NLR, PLR and SII were important factors affecting OS (P < 0.05). For multivariate analysis, the results revealed that the preoperative LCR (HR, 0.401; 95% CI, 0.199-0.807; P = 0.01) and Enneking stage (HR, 2.717; 95%CI, 1.067-6.919; P = 0.036) is an independent prognostic factor affecting the postoperative OS of osteosarcoma.Conclusions: The high preoperative LCR is strongly associated with longer survival time in patients with osteosarcoma. Enneking stage and preoperative LCR may be important parameters for the prognosis of osteosarcoma.
