Forty-one dairy cows (n=41) were enrolled to envisage the changes in uterine haemodynamics during sub-clinical endometritis (SCE) and its treatment with modified estrus synchronization protocols at 8 weeks post-partum. Trans-rectal Doppler sonography of both the middle uterine arteries (MUAs) was carried out for assessment of uterine perfusion whereas serum inflammatory markers i.e. IL-6 and C-RP were measured at 8 weeks post-partum and estrus (induced or spontaneous). Modified estrus synchronization protocols (MG6G and MG6GP) were used to adjudge their efficacy in post-partum dairy cows diagnosed with SCE and reproductive parameters were recorded. As a part of result, Doppler indices of both the MUAs at estrus i.e. TAMEAN, TAMAX, Blood flow volume-TAMEAN and TAMAX and diameter of MUA, were significantly lower (P<0.05) after application of MG6G and MG6GP protocols in SCEP as compared to SCEP control cows. Similarly, the IL-6, C-RP concentrations and PMNCs proportion (%) were significantly higher (P<0.05) in SCEP control as compared to cows treated with MG6G and MG6GP protocols. Moreover, on the day of estrus, the uterine haemodynamics, concentration of serum inflammatory markers and PMNCs proportion (%) in treated cows was at par with SCE negative control (SCEN) cows. In terms of reproductive performance, days open were recorded to be significantly lower (P<0.01) in treated and SCEN group as compared to SCEP control cows. In conclusion, sub-clinical endometritis led higher uterine perfusion, release of proinflammatory cytokines and PMNCs proportion which happened to plummet the post-partum reproductive performance was successfully managed with modified estrus synchronization protocols.

Abstract Background The dietary spice Curcuma longa, also known as turmeric, has various biological effects. Both a water extract and a supercritical carbon dioxide extract of C. longa showed anti-inflammatory activities in animal studies. However, the anti-inflammatory effect in humans of a mixture of these two C. longa extracts (CLE) is poorly understood. Therefore, we investigated the effect of CLE containing anti-inflammatory turmeronols on chronic inflammation and general health. Methods We performed a randomized, double-blind, placebo-controlled study in healthy subjects aged 50 to 69 years with overweight. Participants took two capsules containing CLE (CLE group, n = 45) or two placebo capsules (placebo group, n = 45) daily for 12 weeks, and serum inflammatory markers were measured. Participants also completed two questionnaires: the Medical Outcomes Study (MOS) 36-Item Short-Form Health Survey (SF-36) and the Profile of Mood States (POMS) scale. Treatment effects were analyzed by two way analysis of variance followed by a t test (significance level, p <  0.05). Results After the intervention, the CLE group had a significantly lower body weight (p <  0.05) and body mass index (p < 0.05) than the placebo group and significantly lower serum levels of C-reactive protein (p < 0.05) and complement component 3 (p < 0.05). In addition, the CLE group showed significant improvement of the MOS SF-36 mental health score (p < 0.05) and POMS anger-hostility score (p < 0.05). Conclusion CLE may ameliorate chronic low-grade inflammation and thus help to improve mental health and mood disturbance. Trial registration UMIN-CTR, UMIN000037370.

Abstract Introduction The predictive potential of demographics, clinical characteristics, and inflammatory markers at admission to determine future intubation needs of hospitalised CoVID-19 patients is unknown. The study aimed to determine the predictive potential of elevated serum inflammatory markers in determining the need for intubation in CoVID-19 Patients. Methods In a retrospective cohort study of hospitalised SARS-CoV2 positive patients, single and multivariable regression analyses were used to determine covariate effects on intubation odds, and a minimax concave penalty regularised logistic regression was used to build a predictive model. A second prospective independent cohort tested the model. Results Systemic inflammatory markers obtained at admission were higher in patients that required subsequent intubation, and adjusted odds of intubation increased for every standard deviation above the mean for c-reactive protein (CRP) OR:2.8 (95% CI 1.8-4.5, p<0.001) and lactate dehydrogenase OR:2.1 (95% CI 1.33.3, p=0.002). A predictive model incorporating C-reactive protein, lactate dehydrogenase, and diabetes status at the time of admission predicted intubation status with an area under the curve (AUC) of 0.78 with corresponding sensitivity of 86%, specificity of 63%. This predictive model achieved an AUC of 0.83, 91% sensitivity, and 41% specificity on the validation cohort. Conclusion In patients hospitalised with CoVID-19, elevated serum inflammatory markers measured within the first twenty-four hours of admission are associated with an increased need for intubation. Additionally, a model of C-reactive protein, lactate dehydrogenase, and the presence of diabetes may play a predictive role in determining the future need for intubation.

Background: Inflammatory markers, such as C-reactive Protein (CRP), Interleukin-6 (IL-6), tumor necrosis factor (TNF)-alpha and fibrinogen, are upregulated following acute stroke. Studies have shown associations of these biomarkers with increased mortality, recurrent vascular risk, and poor functional outcome. It is suggested that physical fitness training may play a role in decreasing long-term inflammatory activity and supports tissue recovery.Aim: We investigated the dynamics of selected inflammatory markers in the subacute phase following stroke and determined if fluctuations are associated with functional recovery up to 6 months. Further, we examined whether exposure to aerobic physical fitness training in the subacute phase influenced serum inflammatory markers over time.Methods: This is an exploratory analysis of patients enrolled in the multicenter randomized-controlled PHYS-STROKE trial. Patients within 45 days of stroke onset were randomized to receive either four weeks of aerobic physical fitness training or relaxation sessions. Generalized estimating equation models were used to investigate the dynamics of inflammatory markers and the associations of exposure to fitness training with serum inflammatory markers over time. Multiple logistic regression models were used to explore associations between inflammatory marker levels at baseline and three months after stroke and outcome at 3- or 6-months.Results: Irrespective of the intervention group, high sensitive CRP (hs-CRP), IL-6, and fibrinogen (but not TNF-alpha) were significantly lower at follow-up visits when compared to baseline (p all ≤ 0.01). In our cohort, exposure to aerobic physical fitness training did not influence levels of inflammatory markers over time. In multivariate logistic regression analyses, increased baseline IL-6 and fibrinogen levels were inversely associated with worse outcome at 3 and 6 months. Increased levels of hs-CRP at 3 months after stroke were associated with impaired outcome at 6 months. We found no independent associations of TNF-alpha levels with investigated outcome parameters.Conclusion: Serum markers of inflammation were elevated after stroke and decreased within 6 months. In our cohort, exposure to aerobic physical fitness training did not modify the dynamics of inflammatory markers over time. Elevated IL-6 and fibrinogen levels in early subacute stroke were associated with worse outcome up to 6-months after stroke.Clinical Trial Registration:ClinicalTrials.gov, NCT01953549.

AbstractLong-chain n-3 polyunsaturated fatty acids (PUFA), especially eicosapentaenoic acid (EPA), have been shown to prevent atherosclerosis-related cardiovascular disease, including stroke. Recently, the ratio of serum EPA to arachidonic acid (AA; EPA/AA ratio) has been reported to be a biomarker to prevent cardiovascular disease. In this study, we evaluate whether the serum EPA/AA ratio would be a useful biomarker for determining the efficacy of orally administered EPA in preventing stroke by investigating tissue and serum EPA/AA ratios, serum inflammatory markers, and carotid artery intimamedia thickness (IMT). Patients with dyslipidemia, as the primary illness scheduled for carotid endarterectomy (CEA), were included and randomly assigned to the EPA group (EPA: 1,800 mg/day plus statin; 10 patients) or non-EPA group (statin only; 15 patients). PUFA fraction was evaluated in the tissue (post-CEA) and serum (pre-CEA and 6 months thereafter). As for the tissue PUFA fraction in the plaque, the EPA group had a significantly higher EPA/AA ratio (EPA group, 0.46; non-EPA group, 0.28; p = 0.01). At 6 months postoperatively, the EPA group had a significantly higher serum EPA/AA ratio (baseline, 0.83; follow-up, 1.60; p = 0.05). No significant differences were found for inflammatory markers and IMT. Both serum and tissue EPA/AA ratios were higher in patients treated with oral EPA. Serum EPA/AA ratio might be a useful biomarker for the efficacy of orally administered EPA.

Aim: To determine the viral load in the patients admitted in Covid-19 isolation and its correlation with the inflammatory markers and the following clinical outcome. Methodology: A retrospective study was conducted in the Pathology Department of Doctors Hospital and Medical Centre in Lahore, Pakistan from November 2020 to January 2021. IRB approval was granted. A total of 86 patients met the inclusion criteria for the study. Data was analyzed using research tool SPSS 24. Results: Increased serum viral load in SARS-CoV-2 infection showed positive correlation with inflammatory markers IL-6 (P =0.04) and D-dimer (P =0.029). Inflammatory markers LDH, Ferritin, Procalcitonin, D-Dimers and viral load itself (CT) all correlated with higher mortality while IL-6 did not. Conclusion: Serum viral load in patients infected with SARS-CoV-2 correlates with higher mortality rates itself and also raises certain inflammatory markers (IL-6, D-Dimers), which are independently accountable for causing higher mortality as well. Hence, increased inflammatory markers resulted in poor prognosis regardless of high or low viral load. Their correlation with mortality can still serve as prognostic indicators.
