As the field of interventional pain management (IPM) grows, the risk of surgical site infections (SSIs) is increasing. SSI is defined as an infection of the incision or organ/space that occurs within one month after operation or three months after implantation. It is also common to find patients with suspected infection in an outpatient clinic. The most frequent IPM procedures are performed in the spine. Even though primary pyogenic spondylodiscitis via hematogenous spread is the most common type among spinal infections, secondary spinal infections from direct inoculation should be monitored after IPM procedures. Various preventive guidelines for SSI have been published. Cefazolin, followed by vancomycin, is the most commonly used surgical antibiotic prophylaxis in IPM. Diagnosis of SSI is confirmed by purulent discharge, isolation of causative organisms, pain/tenderness, swelling, redness, or heat, or diagnosis by a surgeon or attending physician. Inflammatory markers include traditional (C-reactive protein, erythrocyte sedimentation rate, and white blood cell count) and novel (procalcitonin, serum amyloid A, and presepsin) markers. Empirical antibiotic therapy is defined as the initial administration of antibiotics within at least 24 hours prior to the results of blood culture and antibiotic susceptibility testing. Definitive antibiotic therapy is initiated based on the above culture and testing. Combination antibiotic therapy for multidrug-resistant Gram-negative bacteria infections appears to be superior to monotherapy in mortality with the risk of increasing antibiotic resistance rates. The never-ending war between bacterial resistance and new antibiotics is continuing. This article reviews prevention, diagnosis, and treatment of infection in pain medicine.

To study the effect of dietary docosahexaenoic acid (DHA) enrichment on the expression of hepatic genes in pigs, weaned, crossbred pigs (30 d old) were fed diets supplemented with either 2% tallow or DHA oil for 18 d. Hepatic mRNA was extracted. Suppression subtractive hybridization was used to explore the hepatic genes that were specifically regulated by dietary DHA enrichment. After subtraction, we observed 288 cDNA fragments differentially expressed in livers from pigs fed either 2% DHA oil or 2% tallow for 18 d. After differential screening, 7 genes were found to be differentially expressed. Serum amyloid A protein 2 (SAA2) was further investigated because of its role in lipid metabolism. Northern analysis indicated that hepatic SAA2 was upregulated by dietary DHA enrichment (p<0.05). In a second experiment, feeding 10% DHA oil for 2d significantly increased the expression of SAA2 (compared to the 10% tallow group; p<0.05). The porcine SAA2 full length cDNA sequence was cloned and the sequence was compared to the human and mouse sequences. The homology of the SAA2 amino acid sequence between pig and human was 73% and between pig and mouse was 62%. There was a considerable difference in SAA2 sequences among these species. Of particular note was a deletion of 8 amino acids, in the pig compared to the human. This fragment is a specific characteristic for the SAA subtype that involved in acute inflammation reaction. Similar to human and mouse, porcine SAA2 was highly expressed in the liver of pigs. It was not detectable in the skeletal muscle, heart muscle, spleen, kidney, lung, and adipose tissue. These data suggest that SAA2 may be involved in mediation of the function of dietary DHA in the liver of the pig, however, the mechanism is not yet clear.

The present study was performed in order to clarify the significance of serum amyloid A(SAA) estimation for the diagnosis of bovine amyloidosis and SAA as a useful parameter for the health status in herds. Twelve dutch dairy cows with final diagnosis(2 with amyloidosis, 3 with acute inflammatory disease and 7 with chronic inflammatory disease) were used to charify the significance of SAA determination for the diagnosis of bovine amyloidosis. The SAA concentration in the group of inflammatory disease was higher than that of amyloldotic group. Further the SAA value in the group of acute inflammatory disease was higher than that of chronic ones. To clarify the significance of SAA estimation as a useful parameter for the health status in herds, two Korean dairy farms(A and B) were selected and the SAA concentration was determined in total 76 cows(49 from A farm and 27 from B farm). The SAA concentration in cows from A farm was ranged with 0～169%. The cows with high level of SAA(31～169%) had the disease histories(1 with retained placenta, 3 with chronic mastitis, 2 with acute mastitis, 1 with abortion and acute mastitis, 1 with ovarian dysfunction, 1 with downer cow syndrome and 1 with laceration of the teat). The SAA value in the cows from B farm was ranged with 0～29% and disease history was not detected. In conclusion the SAA determination only is thought to be difficult for the diagnosis of bovine amyloidosis. Furthermore SAA estimation is thought to be a useful parameter for the health status in herds.

Background: The current study investigates the anti-stress effects of clove (Eugenia caryophyllus) extracts (0, 200, 400, and 600 mg/kg) on serum antioxidant biomarkers, immune response, immunological organ growth index, and expression levels of acute phase proteins (APPs); ovotransferrin (OVT), ceruloplasmin (CP), ceruloplasmin (AGP), C-reactive protein (CRP), and serum amyloid-A (SAA) mRNA in the immunological organs of 63-d-old male black-meated Silkie fowls subjected to 21 d chronic heat stress at $35{\pm}2^{\circ}C$. Results: The results demonstrated that clove extract supplementation in the diet of Silkie fowls subjected to elevated temperature (ET) improve growth performance, immune responses, and suppressed the activities of glutathion peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT), and thioredoxin reductase (TXNRD); reduced serum malonaldehyde (MDA) and glutathione (GSH) concentrations when compared with fowls raised under thermoneutral condition (TC). Upon chronic heat stress and supplementation of clove extracts, the Silkie fowls showed a linear increase in GSH-Px, SOD, CAT, and TXNRD activities (P = 0.01) compared with fowls fed diets without clove extract. ET decreased (P < 0.05) the growth index of the liver, spleen, bursa of Fabricius and thymus. However, the growth index of the liver, spleen, bursa of Fabricius and thymus increased significantly (P < 0.05) which corresponded to an increase in clove supplemented levels. The expression of OVT, CP, AGP, CRP, and SAA mRNA in the liver, spleen, bursa of Fabricius and thymus were elevated (P < 0.01) by ET compared with those maintained at TC. Nevertheless, clove mitigates heat stress-induced overexpression of OVT, CP, AGP, CRP and SAA mRNA in the immune organs of fowls fed 400 mg clove/kg compared to other groups. Conclusions: The results showed that clove extracts supplementation decreased oxidative stress in the heat-stressed black-meated fowls by alleviating negative effects of heat stress via improvement in growth performance, antioxidant defense mechanisms, immunity, and regulate the expression of acute phase genes in the liver and immunological organs.

The 2019 coronavirus outbreak poses a threat to scientific, societal, financial, and health resources. The complex pathogenesis of severe acute respiratory syndrome coronavirus centers on the unpredictable clinical progression of the disease, which may evolve abruptly and result in critical and life-threatening clinical complications. Effective clinical laboratory biomarkers that can classify patients according to risk are essential for ensuring timely treatment, and an analysis of recently published studies found cytokine storm and coagulation disorders were leading factors of severe COVID-19 complications. The following inflammatory, biochemical, and hematology biomarkers markers have been identified in COVID-19 patients; neutrophil to lymphocyte ratio, c-reactive protein, procalcitonin, urea, liver enzymes, lactate dehydrogenase, serum amyloid A, cytokines, d-dimer, fibrinogen, ferritin, troponin, creatinine kinase, and lymphocyte, leukocyte, and platelet counts. These factors are predictors of disease severity and some are involved in the pathogenesis of COVID-19. CRP is an acute-phase, non-specific serological biomarker of inflammation and infection and is related to disease severities and outcomes. In the present study, CRP levels were found to rise dramatically among COVID-19 patients, and our findings suggest CRP could be utilized clinically to predict COVID-19 prognosis and severity even before disease progression and the manifestation of clinical symptoms.

Subcutaneous abscesses, which occur mainly in goats and sheep, are lymph node abscesses caused by Corynebacterium pseudotuberculosis infection, and are divided into internal, external, and mixed types depending on the type of occurrence. While diagnostic methods for subcutaneous abscesses have been continuously studied, research reports for effective treatment and management of subcutaneous abscesses are inadequate. Therefore, this study was conducted to determine the changes in biometric information related to the inflammatory markers of goats induced by subcutaneous abscesses by infection with C. pseudotuberculosis. For this, hematological tests, analysis of inflammatory indicators, and analysis of serum proteins through electrophoresis separation of goats with healthy goats and goats inoculated with C. pseudotuberculosis to induce subcutaneous abscesses were compared and analyzed by date, and the differences and characteristics were identified periodically. As a result, in goats induced with subcutaneous abscesses, anemia findings related to a rapid decrease in red blood cell (RBC), hematocrit (HCT), and hemoglobin (Hb) were observed, and a significant increase in inflammatory cells expressed in total white blood cell (WBC), neutrophil, and monocytes was observed. And the levels of acute phase protein (APP) such as fibrinogen, haptoglobin, and serum amyloid A (SAA) were observed to increase rapidly immediately after infection. In addition, in the results of electrophoretic analysis of serum proteins, it was observed that the levels of α-globulin and β-globulin were significantly increased in goats with subcutaneous abscesses. That is, when looking at these changes, it was found that the systemic inflammatory response of goats was rapidly induced immediately after infection with the C. pseudotuberculosis pathogen. Through this study, it was possible to identify changes in the biomarkers of goats with subcutaneous abscesses, which had not been reported. Furthermore, these analyzed data are thoughts to be of great help in identifying, treating, and managing the goats of subcutaneous abscesses.
