Abstract
Osteoarthritis (OA) is a common joint degenerative disease. There is currently no cure for OA. Dietary fatty acids have potential value in the prevention and treatment of OA. n-3 polyunsaturated fatty acids (PUFAs) have anti-inflammatory effects, but their anti-OA mechanism remains unclear. High-mobility group box 1 (HMGB1) promotes inflammation and participates the pathogenesis of OA. The purpose of this study was to investigate the protective effect of n-3 PUFAs on cartilage and whether n-3 PUFAs could exert an anti-OA effect through inhibiting HMGB1-RAGE/TLR4 signaling pathway. We established an obesity-related post-traumatic OA mice model and an in vitro study was conducted to explore the regulatory mechanism of n-3 PUFAs on HMGB1 and its signal pathway against OA. We found that diet rich in n-3 PUFAs alleviated OA-like lesions of articular cartilage with the decrease of HMGB1-RAGE/TLR4 signaling protein in mice. In SW1353 cells, DHA significantly reduced the expression of HMGB1-RAGE/TLR4 signaling protein which was up-regulated by IL-1β stimulation. HMGB1 overexpression reversed the inhibitory effect of DHA on HMGB1-RAGE/TLR4 signaling pathway. The activation of SIRT1 may participate the inhibitory effect of DHA on HMGB1-RAGE/TLR4 signaling pathway. In conclusion, n-3 PUFAs could attenuate the progression of obesity-related OA and exert protective effect on cartilage by inhibiting HMGB1-RAGE/TLR4 signaling pathway, which may be associated with the activation of SIRT1. Dietary n-3 PUFAs supplements can be considered as a potential therapeutic substance for OA.

Abstract
PURPOSE To evaluate the effect of an anti-inflammatory compared to a low-calorie diet on the physical and mental health of patients with knee OA. METHODS In this randomized parallel clinical trial, participants were selected among overweight and obese women aged 40 years or older with mild to moderate OA. Sixty women with a ratio of 1:1 were randomly assigned to receive either low-calorie or anti-inflammatory accompanied by a low-calorie diet for two months. The dietary intake and weight of participants were measured. Study variables were assessed using the Western Ontario and McMaster Index (WOMAC), visual analog pain scale (VAS), Beck Depression Inventory (BDI-II), Beck Anxiety Inventory (BAI-I), and the Short Form 36 Health Survey Questionnaire (SF-36) to indicate the quality of life (QoL). RESULTS There was no statistically significant difference between the two groups in demographic and baseline variables except for the emotional well-being subscale of QoL. There was significant difference in anti-inflammatory compared to low-calorie diet in terms of weight (MD (95% CI): - 4.02 kg (- 6.77 to - 1.28); p = 0.005), VAS (MD (95% CI): - 0.97 (- 1.53 to - 0.41); p = 0.001), WOMAC-total score (MD (95% CI): - 9.91 (- 15.05 to - 4.78); p < 0.001), WOMAC-pain subscale (MD (95% CI): - 3.30 (- 5.30 to - 1.29); p = 0.002), WOMAC-physical function (MD(95% CI): - 5.48 (- 9.41 to - 1.53); p = 0.007), depression (p = 0.003), anxiety (p = 0.011), QoL-physical functioning (0.041), and QoL-pain (0.010) after the intervention. CONCLUSION An anti-inflammatory accompanied by a low-calorie diet resulted in greater weight loss and greater improvement in pain intensity, functional status, depression, anxiety, and some dimension of QoL in overweight and obese women with knee OA compared to the low-calorie diet. Trial registration number and date of registration: IRCT201610220030424N2; 2018-04-23.

Abstract
Protein carbonylation is an irreversible and degenerative modification that can be used to evaluate oxidative stress caused by glucocorticoids. In this study, we focused on protein carbonylation in dogs with hypercortisolism (HC). Sera samples were collected from 14 dogs diagnosed with HC and treated with trilostane, 12 dogs with inflammatory diseases (disease control group), and eight clinically healthy dogs. When the carbonylated protein levels were detected by the immunoblot analysis, one band of approximately 40 kDa was predominantly increased in the dogs with HC. The band was identified as haptoglobin using the liquid chromatography tandem mass spectrometry method. Furthermore, haptoglobin immune reactivity was higher in the dogs with HC. Although the average protein carbonylation level of the HC group was not significantly different from that of the other groups, the carbonylation level was significantly higher for the poorly controlled HC cases than for the well-controlled HC group. Additionally, the primary culture of canine hepatocytes was used to clarify the direct effect of glucocorticoids on protein carbonylation in dog livers. Both the carbonylated protein and haptoglobin clearly increased after 72 h. These findings suggest that haptoglobin and its carbonylated form are increased with canine HC, and that the protein carbonylation ratio and/or haptoglobin level could be related to disease management. These factors could be useful as biomarkers for an oxidative stress reaction, at least in the liver, and for treatment monitoring of HC.

Abstract
BACKGROUND Fish oil (FO) supplementation as a source of omega 3 fatty acids is associated with beneficial effects on health. However, high unsaturated fatty acid content in the diet could result in increased lipid peroxidation and damage to proteins, lipids and DNA. We evaluated the effect of dietary FO supplementation on DNA damage in peripheral blood lymphocytes of dogs. Additionally, we determined the effect of FO supplementation on lipid peroxidation and lipid profile of these dogs. METHODS Healthy male dogs (n = 9) were randomly assigned to one of two diets during 90 days: control (CG, n = 4), based on a commercial food, and FO (FOG, n = 5), the same food supplemented with 1000 mg FO. Blood samples were collected on days -1, 30, 60 and 90. DNA damage was assessed with the comet assay, and the damage index was obtained. Malondialdehyde (MDA) levels were determined as an indicator of lipid peroxidation. Lipid profile determination included serum triglyceride, cholesterol, low-density lipoprotein and high-density lipoprotein levels (HDL). RESULTS Damage index values (arbitrary units) were lower in FOG on day 30 (CG, 13.7 ± 2.5; FOG, 6.5 ± 2.5), 60 (CG, 14.7 ± 2.5; FOG, 3.5 ± 2.5) and 90 (CG, 15.5 ± 2.5; FOG, 3.0 ± 2.5) compared with CG (treatment × time interaction, p < 0.01). Serum MDA and HDL concentrations were lower in FOG compared with CG on day 60 and 90 (treatment × time interaction, p < 0.05). CONCLUSION These findings suggest that dietary FO supplementation did not induce DNA damage in peripheral blood lymphocytes of healthy dogs, but rather reduced it.

Abstract
Thiobarbituric acid reactive substances (TBARS) are laboratory markers of oxidative stress, which can be used to evaluate the lipid peroxidation that characterizes cell membrane damage caused by excess free radicals. This prospective study aimed to assess TBARS as a parameter of lipid peroxidation in dogs with spontaneous hypercortisolism (HC) at the time of diagnosis, and after trilostane treatment. Furthermore, it aimed to investigate the correlations between TBARS levels, and laboratory and cardiovascular parameters. Sixteen dogs with HC were evaluated at 3 different time points: At diagnosis (T0), 6 mo after treatment (T1), and 12 mo after trilostane treatment (T2). A control group (n = 20) of dogs with a demographic profile similar to the HC group, but considered healthy was selected and evaluated. There was a significant difference (P < 0.001) in TBARS levels between the HC group at diagnosis (4.38 ± 1.16 nmoles MDA/mg protein) and the control group (2.15 ± 0.45 nmoles MDA/mg protein). Dogs in the HC group exhibited a significant reduction (P < 0.001) in TBARS levels after treatment. There was no significant difference in TBARS levels between the control group and the HC group at T1 and T2 evaluation. TBARS positively correlated with left atrial dimensions and hematocrit. The study demonstrates that lipid peroxidation is increased in canine HC and suggests that control of the disease is beneficial to normalize the state of oxidative stress.

Abstract
The objective of this study was to provide preliminary data describing the safety and effect of cannabidiol (CBD) for symptom relief of canine osteoarthritis-associated pain in a clinical setting using objective outcome measures. Twenty-three client-owned dogs with naturally occurring osteoarthritis of appendicular joints completed this prospective, double-blinded, crossover, placebo-controlled study. Baseline data were acquired for 4 wk, followed by random allocation to either placebo or CBD treatment for 6 wk, followed by 6 wk with the opposite treatment. Outcome measures included objective gait analysis, activity counts (via accelerometry) and clinical metrology instruments. There were no differences noted between groups at any time point for any of the recorded outcome measures. Adverse events associated with CBD administration included elevation in liver enzymes (n = 14) and vomiting (n = 2).

Abstract
Clinical improvement of dogs treated for canine leishmaniasis (CanL) requires reducing Leishmania infantum loads, which depend on intracellular oxidant compounds to destroy the parasite. However, oxidative species' excess and antioxidants consumption can culminate in oxidative stress, resulting in increased, widespread inflammation. We aimed to evaluate if early or late addition of nutritional adjuvants (NAs) - omega-3 polyunsaturated fatty acids and B vitamins - to anti-Leishmania drugs (ALDs) in the treatment of CanL would be clinically beneficial. For that, serum biomarkers including oxidative stress parameters were analyzed during 12 months in dogs allocated to two treatment groups: (G1) NAs administered from 30 days prior to the beginning of ALDs; and (G2) NAs administered from 61 days after the beginning of ALDs. Both G1 and G2 continued to receive NAs until the 12th month. The ALDs administered were metronidazole associated with ketoconazole (40 days), followed by allopurinol from day 41 until the 12th month. G1 exhibited superior inflammation control, with reduced globulins (p = 0.025), specific anti-Leishmania immunoglobulins (p = 0.016), total protein (p = 0.031), and an increased serum albumin/globulin ratio (p = 0.033), compared to G2. The early use of NAs associated with ALDs is clinically beneficial in treating dogs with CanL.

Abstract
Long-chain polyunsaturated fatty acids (LCPUFAs) and their metabolites are considered essential factors to support bone and joint health. The n-6 PUFAs suppress the osteoblasts differentiation via increasing peroxisome proliferator-activated receptor gamma (PPARγ) expression and promoting adipogenesis while n-3 PUFAs promote osteoblastogenesis by down-regulating PPARγ and enhancing osteoblastic activity. Arachidonic acid (AA) and its metabolite prostaglandin E2 (PGE2) are key regulators of osteoclast differentiation via induction of the receptor activator of nuclear factor kappa-Β ligand (RANKL) pathway. Marine-derived n-3 LCPUFAs have been shown to inhibit osteoclastogenesis by decreasing the osteoprotegerin (OPG)/RANKL signalling pathway mediated by a reduction of pro-inflammatory PGE2 derived from AA. Omega-3 PUFAs reduce the expression of cartilage degrading enzyme matrix metalloproteinase-13 (MMP-13) and a disintegrin and metalloprotease with thrombospondin motifs-5 (ADAMTS-5) protein, oxidative stress and thereby apoptosis via nuclear factor kappa-betta (NF-kβ) and inducible nitric oxide synthase (iNOS) pathways. In this review, a diverse range of important effects of LCPUFAs on bone cells and chondrocyte was highlighted through different mechanisms of action established by cell cultures and animal studies. This review allows a better understanding of the possible role of LCPUFAs in bone and chondrocyte metabolism as potential therapeutics in combating the pathological complications such as osteoporosis and osteoarthritis.

Abstract
Background: While anecdotal evidence has long claimed that a raw meat-based diet (RMBD) improves the metabolic health of canines, no rigorous scientific study has clarified this issue. Canine atopic dermatitis (CAD) has also been linked to metabolic health, but its relation to diet remains poorly understood. This study investigates whether dietary choice is linked to metabolic health in healthy and CAD-diagnosed canines via targeted serum and urine metabolomic analysis of polar, non-ionic metabolites, as well as whether the underlying CAD condition modulates the response to nutritional intake. Materials and Methods: Serum metabolites of client-owned Staffordshire bull terriers, divided into CAD-diagnosed (n = 14) and healthy (n = 6) cohorts, were studied. Urine metabolites of a subset of the CAD-diagnosed canines (n = 8) were also studied. The canines were split into two cohorts based on diet. The first cohort were fed a commercially available high-fat, moderate-protein, low-carbohydrate RMBD (n = 11, CAD diagnosed n = 8, healthy n = 3). Those in the second cohort were fed a commercially available moderate-fat, moderate-protein, high-carbohydrate kibble diet (KD) (n = 9: CAD diagnosed n = 6, healthy n = 3). The diet intervention period lasted approximately 4.5 months (median 135 days). Statistical analyses of the serum profiles across all dogs (n = 20) and the urine profiles of the CAD-diagnosed subset (n = 8) were performed. Results and Discussion: The KD cohort was found to have higher concentrations of methionine than the RMBD cohort, both in serum (all dogs, p < 0.0001) and in urine (CAD-only cohort, p < 0.0002), as well as cystathionine and 4-pyridoxic acid. Methionine plays important roles in homocysteine metabolism, and elevated levels have been implicated in various pathologies. The CAD (n = 14) cohort dogs showed starker metabolic changes in response to diet regarding these pathways compared to the healthy (n = 6) cohort. However, there was no significant change in CAD severity as a result of either diet. Likely due to the higher meat content of the RMBD, higher concentrations of several carnitines and creatine were found in the RMBD cohort. Citrulline was found in higher concentrations in the KD cohort. Our findings provide insight into the relationship between diet and the serum and urine metabolite profiles of canines. They also suggest that neither diet significantly affected CAD severity.

Lipid and metabolic profiles in female dogs with mammary carcinoma receiving dietary fish oil supplementation. BMC Vet Res 2019; 15:401. [PMID: 31703601 PMCID: PMC6839264 DOI: 10.1186/s12917-019-2151-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2019] [Accepted: 10/22/2019] [Indexed: 02/08/2023] Open
Abstract
Background Dyslipidemias induce angiogenesis and accelerate the development and in vitro growth of breast tumors. The aim of this study was to assess the lipid and metabolic profile of female dogs with mammary carcinomas and their correlations with body condition score and degree of tumor malignancy, as well as to study the effect of dietary fish oil supplementation on these animals. Results Overweight or obese dogs had more aggressive carcinomas and higher triglyceride (p = 0.0363), VLDL (p = 0.0181), albumin (p = 0.0188), globulin (p = 0.0145) and lactate (p = 0.0255) concentrations. There was no change in the lipid profile after supplementation with fish oil at any concentration. However, in relation to the metabolic profile, glucose (p = 0.0067), total protein (p = 0.0002) and globulin (p = 0.0002) concentrations were increased when 90% omega-3 fish oil was used as a dietary supplement. Conclusion Obese dogs showed altered lipid and metabolic profiles and more aggressive tumors, suggesting an important relationship between dyslipidemia and tumor aggressiveness. Supplementation with fish oil, rich in omega-3 fatty acids, may alter metabolic parameters in cancer patients.

Abstract
The objective of this study was to assess veterinarians' understanding of nutraceutical use in humans and companion animals and their motivation and circumstances for recommending nutraceuticals to clients. We administered a cross-sectional survey to veterinarians attending continuing education sessions at the University of Georgia (USA) College of Veterinary Medicine from 2012 to 2015 (N = 126). Information regarding veterinarians' age, year of graduation, practice focus, and typical approaches to nutraceutical use was compiled from the returned surveys. The results indicated that veterinarians are more familiar with nutraceutical use in animals than in humans and primarily recommend nutraceuticals to their clients for preventative purposes and/or due to client interest. Veterinarians believed that nutraceuticals were most useful for osteoarthritis and therefore use omega-3 fatty acid and glucosamine/chondroitin products more often than other products for both their patients and their own pets. Safety and efficacy were the most important considerations when deciding which nutraceuticals to recommend to clients. The survey results show that veterinarians are familiar with nutraceuticals and open to their use in patients when they perceive these products to be safe and efficacious.

Abstract
Omega-3 polyunsaturated fatty acids (PUFAs) are considered immunonutrients and are commonly used in the nutritional therapy of cancer patients due to their ample biological effects. Omega-3 PUFAs play essential roles in cell signaling and in the cell structure and fluidity of membranes. They participate in the resolution of inflammation and have anti-inflammatory and antinociceptive effects. Additionally, they can act as agonists of G protein-coupled receptors, namely, GPR40/FFA1 and GPR120/FFA4. Cancer patients undergo complications, such as anorexia-cachexia syndrome, pain, depression, and paraneoplastic syndromes. Interestingly, the 2017 European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines for cancer patients only discuss the use of omega-3 PUFAs for cancer-cachexia treatment, leaving aside other cancer-related complications that could potentially be managed by omega-3 PUFA supplementation. This critical review aimed to discuss the effects and the possible underlying mechanisms of omega-3 PUFA supplementation in cancer-related complications. Data compilation in this critical review indicates that further investigation is still required to assess the factual benefits of omega-3 PUFA supplementation in cancer-associated illnesses. Nevertheless, preclinical evidence reveals that omega-3 PUFAs and their metabolites might modulate pivotal pathways underlying complications secondary to cancer, indicating that this is a promising field of knowledge to be explored.

Abstract
The aim of this study was to investigate the effect of boron on the repair of osteochondral defect and also on some antioxidant and oxidant parameters of both cartilage tissue and blood. A total of 24 adult male Wistar rats weighing between 350 and 400 g were used in the study. Animals were randomly divided into control (n = 8), boron (n = 8) and hyaluronic acid (HA) groups (n = 8). Under general anesthesia, a cylindrical full-thickness osteochondral defect 1.5 mm in diameter and 2 mm in depth was formed using a drill on the anterior side of the articular surface of the femur condyle. Boron group received 0.1 ml (10 mg/kg) of boron and HA group received 0.1 ml of HA, whereas control group received 0.1 ml of physiological saline solution. All agents administered intraarticular route and once a week for four times. At the end of the third month, the animals were euthanized and blood and joint tissue malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), and catalase levels were measured. Defected femoral condyles of the rats were removed for a histopathological examination. Histopathology revealed that the total cartilage repair score of the HA group was better than those detected in boron and control groups. Blood and articular cartilage GSH, SOD, and catalase levels were higher in the boron and HA groups as compared to the control group, while MDA level was lower compared to the control group. In conclusion, it was suggested that boron was not as effective as HA in the repair of osteochondral defect, but its antioxidant property was superior to HA.

Abstract
Although dogs' life expectancies are six to twelve times shorter than that of humans, the demographics (e. g., living conditions) of dogs can still change considerably with aging, similarly to humans. Despite the fact that the dog is a particularly good model for human healthspan, and the number of aged dogs in the population is growing in parallel with aged humans, there has been few previous attempts to describe demographic changes statistically. We utilized an on-line questionnaire to examine the link between the age and health of the dog, and owner and dog demographics in a cross-sectional Hungarian sample. Results from univariate analyses revealed that 20 of the 27 demographic variables measured differed significantly between six dog age groups. Our results revealed that pure breed dogs suffered from health problems at a younger age, and may die at an earlier age than mixed breeds. The oldest dog group (>12 years) consisted of fewer pure breeds than mixed breeds and the mixed breeds sample was on average older than the pure breed sample. Old dogs were classified more frequently as unhealthy, less often had a “normal” body condition score, and more often received medication and supplements. They were also more often male, neutered, suffered health problems (such as sensory, joint, and/or tooth problems), received less activity/interaction/training with the owner, and were more likely to have experienced one or more traumatic events. Surprisingly, the youngest age group contained more pure breeds, were more often fed raw meat, and had owners aged under 29 years, reflecting new trends among younger owners. The high prevalence of dogs that had experienced one or more traumatic events in their lifetime (over 40% of the sample), indicates that welfare and health could be improved by informing owners of the greatest risk factors of trauma, and providing interventions to reduce their impact. Experiencing multiple life events such as spending time in a shelter, changing owners, traumatic injury/prolonged disease/surgery, getting lost, and changes in family structure increased the likelihood that owners reported that their dogs currently show behavioral signs that they attribute to the previous trauma.

Abstract
While the association between obesity and osteoarthritis used to be solely regarded as a result of increased mechanical loading, systemic factors also likely play a role in the pathophysiology of osteoarthritis. Nutrient excess leading to obesity may result in lipotoxicity, which might be involved in the development of osteoarthritis. The different fatty acid types have distinct effects on inflammation. This review focusses on the currently available studies, summarizing the effects of the different fatty acid types on osteoarthritis and involved joint tissues. In animal studies omega-3 polyunsaturated fatty acids reduced the expression of inflammatory markers, cartilage degradation and oxidative stress in chondrocytes. In contrast, these markers were increased upon omega-6 polyunsaturated fatty acid and saturated fatty acid stimulation. Additionally, a decrease in pain and dysfunction was observed upon omega-3 supplementation in cats and dogs. In line, most human in vitro studies show pro-apoptotic and pro-inflammatory actions of saturated fatty acids. While all polyunsaturated fatty acids reduced markers of oxidative stress, omega-3 polyunsaturated fatty acids additionally decreased prostaglandin production. Human intervention studies with omega-3 polyunsaturated fatty acid supplementation may indicate a beneficial effect on pain and function and might be associated with less structural damage. In contrast, an adverse effect of saturated fatty acids on osteoarthritis has been observed. Monounsaturated fatty acids have been infrequently studied and findings are inconclusive. Existing studies indicate a promising effect of especially omega-3 polyunsaturated fatty acids on osteoarthritis signs and symptoms. However, more human intervention studies are warranted to draw robust conclusions.

Abstract
The goal of this study was to evaluate the effectiveness of an oral joint supplement in working dogs with hip osteoarthritis compared with a positive control group (CG). Fifteen animals were divided in treatment group (TG, n = 10) and CG (n = 5). To TG a commercially available joint supplement, containing glucosamine HCl, chondroitin sulphate, and hyaluronic acid was given for 40 days and a 70-day course of a placebo, to be administered as if it was carprofen. The CG received carprofen for 70 days, and a placebo to be administered as the joint supplement. Response to treatment, measured by the canine brief pain inventory (CBPI) and the Hudson visual analog scale, was evaluated before treatment (T0), after 15 days (T1) and 1 (T2), 2 (T3), 3 (T4), 4 (T5), and 5 (T6) months. With CBPI, no differences were found in pain interference score and pain severity score between TG and CG throughout or when comparing results within groups. Individual results were considered successful in a maximal of three dogs of the TG by T3 (30%) and 1 in CG (25%). With Hudson visual analog scale, improvements where registered with individual results, for 40%-50% of the animals in TG and 60%-80% of cases in CG. The oral joint supplement and carprofen produced some improvements in individual scores but where unable to do so when overall results were considered. Each of these options may not be able, by itself, to fully address the demands of a working dog with joint disease and related pain.
