Abstract
Viscosupplementation consists of hyaluronic acid (HA) intra-articular injections, commonly applied for osteoarthritis treatment while non-steroidal anti-inflammatory drugs (NSAIDs) are widely administered for pain relief. Here, HA and a NSAID (celecoxib) were combined in a formulation based on a low transition temperature mixture (LTTM) of glycerol:sorbitol, reported to increase celecoxib's solubility, thus rendering a potential alternative viscosupplement envisioning enhanced therapeutic efficiency. The inclusion of glucosamine, a cartilage precursor, was also studied. The developed formulations were assessed in terms of rheological properties, crucial for viscosupplementation: the parameters of crossover frequency, storage (G') and loss (G'') moduli, zero-shear-rate viscosity, stable viscosity across temperatures, and shear thinning behaviour, support viscoelastic properties suitable for viscosupplementation. Additionally, the gels biocompatibility was confirmed in chondrogenic cells (ATDC5). Regarding drug release studies, high and low clearance scenarios demonstrated an increased celecoxib (CEX) release from the gel (6 to 73-fold), compared to dissolution in PBS. The low clearance setup presented the highest and most sustained CEX release, highlighting the importance of the gel structure in CEX delivery. NMR stability studies over time demonstrated the LTTM+HA+CEX (GHA+CEX) gel as viable candidate for further in vivo evaluation. In sum, the features of GHA+CEX support its potential use as alternative viscosupplement.

Abstract
This study is a randomized, placebo-controlled, double-blinded trial performed to investigate the effects of a dietary supplement containing a mixture of Boswellia serrata Roxb., chlorophyll, green tea extract, glucosamine, chondroitin sulfate, hyaluronic acid, and further in the manuscript: non-hydrolised type II collagen in dogs with osteoarthritis (OA). A total of 40 dogs were enrolled in the study, they were randomly divided in control (CTR) and treatment (TRT) groups. The TRT group received the dietary supplement for 60 days. The CTR group received a placebo for the same number of days. All the subjects had veterinary evaluations during the trial and owners were requested to fill in questionnaires on chronic pain using the Helsinki Chronic Pain Index. The product was easy to administer and no side effects were reported. Combining results from veterinarian and owner evaluations, the tested product proved to be significantly beneficial in alleviating pain and in reducing the clinical signs in dogs with OA.

Abstract
BACKGROUND Hyaluronan (HA), glucosamine, and chondroitin sulfate are widely consumed as dietary supplements for the treatment of knee osteoarthritis (OA). This study aimed to explore the efficacy and safety of a dietary liquid supplement mixture containing HA, glucosamine, and chondroitin in patients with knee OA who had moderate knee pain (visual analogue scale of 4-6 points). METHODS This was a short-term, randomized, double-blind, placebo-controlled study. Subjects were allocated to administer either a bottle of 20 mL supplement mixture (50 mg HA plus 750 mg glucosamine plus 250 mg chondroitin, namely A + HA) or placebo once daily for 8 weeks. Outcome measures included the Knee Injury and Osteoarthritis Outcome Score, Western Ontario and McMaster Universities Osteoarthritis Index, 36-item Short Form Survey (SF-36), Chinese version of Pittsburgh Sleep Quality Index, and incidence of adverse event were evaluated at the end of week 8. Efficacy analyses were conducted in the modified intent-to-treat population. RESULTS Of the 80 subjects in the modified intent-to-treat population, 39 received A + HA while 41 received placebo. After 8 weeks of treatment, the A + HA group failed to demonstrate a significant symptomatic efficacy and quality of life improvement in terms of Knee Injury and Osteoarthritis Outcome Score, Western Ontario and McMaster Universities Osteoarthritis Index, SF-36, and Chinese version of Pittsburgh Sleep Quality Index as compared to the placebo group. However, the mean changes in most of the SF-36 scale scores were numerically higher in the A + HA group than in the placebo group. No treatment-related adverse event was reported in both groups. CONCLUSIONS This present study found that the combination of liquid low molecular weight HA, glucosamine, and chondroitin oral supplement did not effectively improve knee OA pain and symptoms after short-term use in knee OA patients with moderate knee pain. However, these results should be interpreted with caution due to the intrinsic limitation of the study design.

Abstract
Glucosamine (GLU) is a natural compound found in cartilage, and supplementation with glucosamine has been shown to improve joint heath and has been linked to reduced mortality rates. GLU is poorly absorbed and may exhibit functional properties in the gut. The purpose of this study was to examine the impact of glucosamine on gastrointestinal function as well as changes in fecal microbiota and metabolome. Healthy males (n = 6) and females (n = 5) (33.4 ± 7.7 years, 174.1 ± 12.0 cm, 76.5 ± 12.9 kg, 25.2 ± 3.1 kg/m2, n = 11) completed two supplementation protocols that each spanned three weeks separated by a washout period that lasted two weeks. In a randomized, double-blind, placebo-controlled, crossover fashion, participants ingested a daily dose of GLU hydrochloride (3000 mg GlucosaGreen®, TSI Group Ltd., Missoula, MT, USA) or maltodextrin placebo. Study participants completed bowel habit and gastrointestinal symptoms questionnaires in addition to providing a stool sample that was analyzed for fecal microbiota and metabolome at baseline and after the completion of each supplementation period. GLU significantly reduced stomach bloating and showed a trend towards reducing constipation and hard stools. Phylogenetic diversity (Faith's PD) and proportions of Pseudomonadaceae, Peptococcaceae, and Bacillaceae were significantly reduced following GLU consumption. GLU supplementation significantly reduced individual, total branched-chain, and total amino acid excretion, with no glucosamine being detected in any of the fecal samples. GLU had no effect on fecal short-chain fatty acids levels. GLU supplementation provided functional gut health benefits and induced fecal microbiota and metabolome changes.

Abstract
BACKGROUND The popularity of dietary supplements for knee osteoarthritis (OA) management is on the rise; however, their effects are still debated. METHODS This study aimed to investigate the effect of an oral low molecular weight liquid hyaluronic acid supplement in the treatment of knee OA patients with mild knee pain (visual analogue scale [VAS] ≤ 3) in Taiwan population. This was a randomized, double-blind, placebo-controlled study. Forty-seven subjects were enrolled and randomly allocated to either the A+HA or the placebo groups. The subjects were required to drink a bottle contained 20 mL of A+HA or placebo daily throughout an 8-week study period. The efficacy was assessed by using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the 36-item Short Form Survey (SF-36). RESULTS At Week 8, significant reductions from baseline in the WOMAC pain (-2.6 ± 1.68, P < .0001), stiffness (-1.2 ± 1.50, P = .007), physical function (-5.8 ± 4.39, P < .0001), and total (-9.4 ± 5.82, P < .0001) scores were observed in the A+HA group but not in the placebo group. Significant differences in the mean change of WOMAC scores from baseline at Week 8 between groups were detected (P < .01). At Week 8, the A+HA group also showed significant improvements in SF-36 physical functioning (2.7 ± 3.10, P = .001) and bodily pain (0.7 ± 1.50, P < .05) domains. Although the A+HA group had a higher increase in the SF-36 total score than the placebo group but the difference was not statistically significant (2.1 ± 12.75 vs 0.3 ± 19.66, P = .12). CONCLUSIONS Oral administration of low molecular weight liquid HA appeared to be effective for knee OA patients with mild knee pain (VAS ≤ 3) in the relief of knee OA symptoms, particularly in pain and physical function.Clinical Trial Registration: NCT04352322.

Abstract
The use of dietary supplements for weight loss has gained significant momentum. Polyglucosamine, a chitosan derivative, is a dietary supplement increasingly used for weight loss. In this meta-analysis, we systematically summarized and quantified the key findings of four randomized, placebo-controlled clinical trials examining the effects of polyglucosamine supplementation and caloric restriction, and physical activity on body weight, body mass index (BMI), and waist circumference in subjects with overweight and obesity. The control group was set with a physical activity from 6–7 MET-h/week activity and up to 21 MET-h/week activity with caloric restriction. Compliance in the latter trials was reported via a follow-up questionnaire with the individual participants. The analysis included 399 subjects followed for a period ranging from 12 weeks to one year. Subjects’ age ranged from 21–75 years, BMI from 26–45 kg/m2, and all were white European or Caucasian in ethnicity. The meta-analyzed mean differences for random effects showed that polyglucosamine supplementation improves weight loss by −1.78 kg [−2.78, −0.79], BMI by −1.52 kg/m2 [−3.58, 0.54], and improves waist circumference reduction by −1.45 cm [−2.77, −0.12]. In conclusion, the use of polyglucosamine supplementation in conjunction with lifestyle behavioral therapies can be effective for weight reduction. Further studies are needed to examine the long-term effects of polyglucosamine supplementation on weight loss and other metabolic parameters

Abstract
Osteoarthritis is a degenerative disease that causes substantial changes in joint tissues, such as cartilage degeneration and subchondral bone sclerosis. Chondroitin sulfate and glucosamine are commonly used products for the symptomatic treatment of osteoarthritis. The aim of the present study was to investigate the effects of these products when used as structure-modifying drugs on the progression of osteoarthritis in the rabbit temporomandibular joint. Thirty-six New Zealand rabbits were divided into 3 groups (n = 12/group): control (no disease); osteoarthritis (disease induction); and treatment (disease induction and administration of chondroitin sulfate and glucosamine). Osteoarthritis was induced by intra-articular injection of monosodium iodoacetate. Animals were killed at 30 and 90 days after initiation of therapy. The treatment was effective in reducing disease severity, with late effects and changes in the concentration of glycosaminoglycans in the articular disc. The results indicate that chondroitin sulfate and glucosamine may have a structure-modifying effect on the tissues of rabbit temporomandibular joints altered by osteoarthritis.

Abstract
The article discusses the place of symptomatic slow-acting drugs in current guidelines for the treatment of osteoarthritis. Special emphasis is put ot glucosamine preparations, the attitude towards which, until recently, was ambiguous. The results of experimental and clinical studies demonstrating the advantages of crystalline glucosamine sulfate over preparations/food additives of glucosamine hydrochloride are presented. The differences in the pharmacodynamics and pharmacokinetics of glucosamine sulfate and glucosamine hydrochloride, which may be the reason for the ineffectiveness of the latter in clinical trials, are discussed.

Abstract
INTRODUCTION Severe acute malnutrition (SAM) in children in many countries still carries unacceptably high mortality, especially when complicated by secondary infection or metabolic derangements. New therapies are urgently needed and we have identified mucosal healing in the intestine as a potential target for novel treatment approaches. METHODS AND ANALYSIS The TAME trial (Therapeutic Approaches for Malnutrition Enteropathy) will evaluate four novel treatments in an efficient multi-arm single-blind phase II design. In three hospitals in Zambia and Zimbabwe, 225 children with SAM will be randomised to one of these treatments or to standard care, once their inpatient treatment has reached the point of transition from stabilisation to increased nutritional intake. The four interventions are budesonide, bovine colostrum or N-acetyl glucosamine given orally or via nasogastric tube, or teduglutide given by subcutaneous injection. The primary endpoint will be a composite score of faecal inflammatory markers, and a range of secondary endpoints include clinical and laboratory endpoints. Treatments will be given daily for 14 days, and evaluation of the major endpoints will be at 14 to 18 days, with a final clinical evaluation at 28 days. In a subset of children in Zambia, endoscopic biopsies will be used to evaluate the effect of interventions in detail. ETHICS AND DISSEMINATION The study has been approved by the University of Zambia Biomedical Research Ethics Committee (006-09-17, dated 9th July, 2018), and the Joint Research Ethics Committee of the University of Zimbabwe (24th July, 2019). Caregivers will provide written informed consent for each participant. Findings will be disseminated through peer-reviewed journals, conference presentations and to caregivers at face-to-face meetings. TRIAL REGISTRATION NUMBER NCT03716115; Pre-results.

Abstract
BACKGROUND Osteoarthritis (OA) is a disorder involving deterioration of articular cartilage and underlying bone and is associated with symptoms of pain and disability. Glucosamine is a component of articular cartilage naturally synthesized in the body from glucose and incorporated into substances contained in the cartilage. It has been suggested that consumption of glucosamine may reduce the pain of OA and may have favorable effects on structural changes in the cartilage. This article presents a systematic review and meta-analysis of the effectiveness of orally consumed glucosamine sulfate (GS) on OA-related pain and joint structural changes. METHODS PubMed and Ovid Embase were searched using specific search terms to find randomized, double-blinded, placebo-controlled trials on the effects of GS on pain and/or joint-space narrowing. The outcome measure was the standardized mean difference (SMD), which was the improvement in the placebo groups minus the improvement in the GS groups divided by the pooled standard deviation. RESULTS There were 17 studies meeting the review criteria for pain, and the summary SMD was -0.35, with a 95% confidence interval (95% CI) = -0.54 to -0.16 (negative SMD is in favor of GS). Of the 17 studies, 7 showed a statistically significant reduction in pain from GS use. Four studies met the review criteria for joint space narrowing with a summary SMD = -0.10 (95% CI = -0.23 to +0.04). Studies without involvement of the commercial glucosamine industry had a lower (but still significant) pain reduction efficacy (summary SMD = -0.19, 95% CI = -0.39 to -0.02) than those with industry involvement. Several smaller dosages throughout the day had larger pain reduction effects than a single daily large dose (1500 mg). CONCLUSION These data indicate that GS may have a small to moderate effect in reducing OA-related pain but little effect on joint-space narrowing. Until there is more definitive evidence, healthcare providers should be cautious in recommending use of GS to their patients. Because GS dosages used in studies to date resulted in mild and transient adverse effects, and these were similar to that experienced by patients receiving placebos, larger GS doses possibly could be investigated in future studies.

Abstract
AIM Evaluation of the effect of glucosamine-chondroitin combination, tramadol, and sodium hyaluronic acid in temporomandibular joint (TMJ) disorders and its impact on the expression of various cytokines such as IL-6, IL-1β, TNF-α, and PGE2. MATERIALS AND METHODS The present study was conducted on 60 patients (males-30, females-30) suffering from internal derangement such as disc displacement with reduction of TMJ. The patients were divided into three groups of 20 each. Group I received a combination of 1.5g of glucosamine and 1.2 g of chondroitin sulfate per day and group II received 50 mg tramadol HCL peroral. Group III received sodium hyaluronate 10 mg/mL, 2 mL injection syringe on each joint. Pain (VAS) scale and maximum mouth opening (MMO) was measured. The level of IL-6, IL-1β, TNF-α, and PGE2 levels were measured using Enzyme-linked immuno sorbent assay (ELISA). RESULTS There was an improvement in maximum mouth opening in all three groups (p < 0.05). There was a reduction in pain in all groups. IL- 1β, TNF-α, and PGE2 leve ls showed reduction while IL-6 showed an increase in value in group II and III. CONCLUSION The efficacy of glucosamine chondroitin sulfate , tramadol and hyaluronic acid in TMJ disorders has been found to be effective. CLINICAL SIGNIFICANCE IL-6, IL-1β, TNF-α, and PGE2 levels indicate the risk of TMJ disorders. Thus earlier assessment of their levels helps in diagnosis, and better management may be done.

Abstract
INTRODUCTION Three out of four people with diabetes will die of cardiovascular disease. However, the molecular mechanisms by which hyperglycemia promotes atherosclerosis, the major underlying cause of cardiovascular disease, are not clear. OBJECTIVES Three distinct models of hyperglycemia-associated accelerated atherosclerosis were used to identify commonly altered metabolites and pathways associated with the disease. METHODS Normoglycemic apolipoprotein-E-deficient mice served as atherosclerotic control. Hyperglycemia was induced by multiple low-dose streptozotocin injections, or by introducing a point-mutation in one copy of insulin-2 gene. Glucosamine-supplemented mice, which experience accelerated atherosclerosis to a similar extent as hyperglycemia-induced models without alterations in glucose or insulin levels, were also included in the analysis. Untargeted plasma metabolomics were used to investigate hyperglycemia-associated accelerated atherosclerosis in three disease models. The effect of specific significantly altered metabolites on pro-atherogenic processes was investigated in cultured human vascular cells. RESULTS Hyperglycemic and glucosamine-supplemented mice showed distinct metabolomic profiles compared to controls. Meta-analysis of three disease models revealed 62 similarly altered metabolite features (FDR-adjusted p < 0.05). Identification of shared metabolites revealed alterations in glycerophospholipid and sphingolipid metabolism, and pro-atherogenic processes including inflammation and oxidative stress. Post-multivariate and pathway analyses indicated that the glycosphingolipid pathway is strongly associated with hyperglycemia-induced accelerated atherosclerosis in these atherogenic mouse models. Glycosphingolipids induced oxidative stress and inflammation in cultured human vascular cells. CONCLUSION Glycosphingolipids are strongly associated with hyperglycemia-induced accelerated atherosclerosis in three distinct models. They also promote pro-atherogenic processes in cultured human cells. These results suggest glycosphingolipid pathway may be a potential therapeutic target to block or slow atherogenesis in diabetic patients.

Abstract
The aim of the stuy was to observe and analyze the effect of glucosamine hydrochloride tablets on patients with cervical spondylosis. This study was conducted on 130 patients diagnosed with cervical spondylosis who were treated in our hospital. The time period was from June 2015 to December 2017. The subjects were randomly divided into a reference group treated with cervical vertebra exercises and cervical occipital belt traction therapy and the study group was further treated with glucosamine hydrochloride tablets. The treatment efficacy of both groups was observed. Comparison of the overall treatment efficiency of patients showed that compared with the reference group, the study group has more significant advantages, P<0.05; comparison of the overall patient satisfaction rate showed that the study group was also superior to the reference group, P<0.05; In addition, statistical analysis of adverse reactions showed no statistically significant difference, P<0.05. The treatment of glucosamine hydrochloride tablets in patients with cervical spondylosis can achieve ideal results, improve the overall treatment efficiency, and thus, has important application significance.

Abstract
OBJECTIVES To compare the efficacies of oral glucosamine, chondroitin, the combination of glucosamine and chondroitin, acetaminophen and celecoxib on the treatment of knee and/or hip osteoarthritis. METHODS We searched electronic databases including PubMed, Embase, and Cochrane Library and the reference lists of relevant articles published from inception to October 23, 2017. A Bayesian hierarchical random effects model was used to examine the overall effect size among mixed multiple interventions. RESULTS We identified 61 randomised controlled trials of patients with knee and/or hip osteoarthritis. There was no obvious difference in the results between the traditional meta-analysis and the network meta-analysis. The network meta-analysis demonstrated that celecoxib was most likely the best option (SMD, -0.32 [95% CI, -0.38 to -0.25]) for pain, followed by the combination of glucosamine and chondroitin. For physical function, all interventions were significantly superior to oral placebo except for acetaminophen. In terms of stiffness, glucosamine (SMD, -0.36 [95% CI, -0.67 to -0.06]) and celecoxib (SMD, -0.29 [95% CI, -0.51 to -0.08]) were significantly better compared to placebo. In view of safety, compared to placebo only, celecoxib and acetaminophen presented significant differences. CONCLUSIONS Given the effectiveness of these non-steroidal anti-inflammatory drugs and symptomatic slow-acting drugs, oral celecoxib is more effective than placebo on relieving pain and improving physical function, followed by the combination of glucosamine and chondroitin. Acetaminophen is likely the least efficacious intervention option. This information, accompanied by the tolerability and economic costs of the included treatments, would be conducive to making decisions for clinicians.

Abstract
BACKGROUND/AIMS Osteoarthritis (OA), the commonest joint disorder, is a leading cause of disability. Symptomatic slow-acting drugs for OA (SYSADOA), particularly glucosamine plus chondroitin sulphate (GS/CS), are effective for symptom relief, protect joint cartilage and delay OA progression, with a good safety profile. D-002, a mixture of beeswax alcohols that inhibits both cyclooxygenase and 5-lipoxygenase activities, has been effective in experimental and clinical OA studies, showing also a chondroprotective effect. OBJECTIVES To compare the effects of D-002 and GS/SC administered for 12 weeks on OA symptoms. METHODS Participants were randomized to GS/CS (375/300 mg) or 50 mg D-002 once daily for 12 weeks. Symptoms were assessed by the Western Ontario and McMaster Individual Osteoarthritis Index (WOMAC) and the Visual Analogy Scale (VAS) scores. The primary outcome was the reduction of the total WOMAC score. Secondary outcomes included WOMAC pain, stiffness and function scores, VAS score and rescue medication consumption. RESULTS Of 60 randomized patients, 59 completed the study. D-002 and GS/SC reduced significantly total WOMAC score (72.1% and 78.5%, respectively), and pain, joint stiffness and physical function scores versus baseline. VAS scores decreased significantly with D-002 (76.6%) and GS/SC (76.8%). The reductions, significant from the second week, were enhanced over the trial. Rescue medications were consumed by 3/30 D-002 and 4/30 GS/SC patients. No differences between groups were found. Treatments were well tolerated. CONCLUSIONS D-002 (50 mg/day) administered for 12 weeks was safe and comparable to GS/SC for alleviating OA symptoms (pain, stiffness, and functional limitation) (RPCEC00000180).

Abstract
Acute kidney injury is a leading contributor to morbidity and mortality in the ageing population. Proteotoxic stress response pathways have been suggested to contribute to the development of acute renal injury. Recent evidence suggests that increased synthesis of N-glycan precursors in the hexosamine pathway as well as feeding of animals with aminosugars produced in the hexosamine pathway may increase stress resistance through reducing proteotoxic stress and alleviate pathology in model organisms. As feeding of the hexosamine pathway metabolite glucosamine to aged mice increased their life expectancy we tested whether supplementation of this aminosugar may also protect mice from acute kidney injury after renal ischemia and reperfusion. Animals were fed for 4 weeks ad libitum with standard chow or standard chow supplemented with 0.5% N-acetylglucosamine. Preconditioning with caloric restriction for four weeks prior to surgery served as a positive control for protective dietary effects. Whereas caloric restriction demonstrated the known protective effect both on renal function as well as survival in the treated animals, glucosamine supplementation failed to promote any protection from ischemia-reperfusion injury. These data show that although hexosamine pathway metabolites have a proven role in enhancing protein quality control and survival in model organisms oral glucosamine supplementation at moderate doses that would be amenable to humans does not promote protection from ischemia-reperfusion injury of the kidney.

Abstract
OBJECTIVES To evaluate the efficacy and safety of combined treatment of mud-bath therapy and glucosamine crystalline sulfate (GlcN-S) in patients with knee osteoarthritis (OA). METHODS This study was a randomised, controlled, crossover investigation. Patients were randomly assigned (1:1) by the investigators to two groups, named group 1 and 2. Group 1 included twenty-three patients receiving oral GlcN-S treatment from the beginning of the study (T0) to the end of the 3rd month of treatment (T3) and a combined treatment of both mud-bath therapy and GlcN-S from T3 to the end of the study at six months (T6). Group 2 included twenty-two patients receiving a combined treatment of both mud-bath therapy and GlcN-S from T0 to T3 and that discontinued mud-bath therapy, receiving GlcN-S treatment alone, from T3 to T6. Primary endpoints of the study consisted of evaluating OA severity and activity at baseline and at follow-up visits. RESULTS All 45 patients, eligible for the study, completed the period of the crossover. In group 1, no significant difference was shown in the comparison from T0 to T3, while from T3 to T6 most variables were significantly improved. In group 2, instead, the comparison between T0 and T3 showed a significant difference in different parameters. When comparing T3 and T6, despite an improvement of all the variables, no significant difference was shown. CONCLUSIONS The association of GlcN-S and mud-bath therapy has a positive and safe role in improving pain, function and quality of life in knee OA patients.

Abstract
Oral glucosamine was compared to a placebo for the management of cats with feline idiopathic cystitis (FIC) in a randomised, double-blinded, placebo-controlled, study. Forty cats with a history of recurrent cystitis due to FIC were divided into two groups and treated daily per os with either 125 mg N-acetyl glucosamine or a placebo for six months. Owners graded their cats' clinical signs at the beginning and end of the study, and kept daily diaries documenting signs of cystitis using visual analogue scales. Further episodes of cystitis were seen in 26 (65%) of the cats during the study. Affected cats experienced a mean of five recurrences (range 1–19) with each recurrence lasting a mean of four days (range 1–64 days). There were no significant differences between the two groups when considering the owners assessments of the mean health score ( P > 0.5), the average monthly clinical score ( P = 0.22) or the average number of days with clinical signs ( P = 0.28). Two cats suffered from such severe recurrent urethral obstruction that they were euthanased; they were both in the placebo group. Compared to the start of the study the majority of cats in both groups improved significantly ( P < 0.001) (mean health score of each group at the start was 0.5 ± SD 0.5, compared to glucosamine 4.4 ± 0.7 and placebo 3.9 ± 1.6 at the end). This is believed to have occurred because the owners of 36 of the 40 cats (90%) started feeding more canned cat food. The urine specific gravity at the start of the trial was significantly higher (mean 1.050 ± SD 1.007) than when reassessed one month later (1.036 ± 1.010, P < 0.01).

Abstract
BACKGROUND Knee osteoarthritis (OA) conservative treatment aims to delay cartilage degeneration; chondroprotective agents are a valid approach in this sense. A commercially available dietary supplement, CartiJoint Forte, containing glucosamine hydrochloride (GH), chondroitin sulfate (CS) and Bio-Curcumin BCM-95®, was used in this trial. AIM The aim of this study was to assess efficacy and safety of CartiJoint Forte combined with physical therapy in treating subjects with knee OA. DESIGN A multicenter, prospective, randomized, double blind, placebo-controlled clinical trial. SETTING Outpatients referred to the Rehabilitation Departments of two University Hospitals. POPULATION Fifty-three patients were randomly assigned to an experimental group (N=26) or a control group (N.=27). Experimental subjects received two tablets of CartiJoint Forte each day for 8 weeks, while those in the control group were provided with a placebo. Three subjects dropped out during the course of the study. METHODS The two groups both received 20 sessions of physical therapy during the course of the trial. Primary outcome was pain intensity, measured both at motion and at rest, using the Visual Analogue Scale (VAS). A secondary outcome was an assessment of knee function by Western Ontario and McMaster Universities Arthritis Index and Lequesne Index, knee ROM, and two inflammation markers (C-reactive protein and erythrocyte sedimentation rate). Each assessment was carried out at baseline (T0), at 8 weeks (T1) and at 12 weeks (T2). RESULTS VAS at rest was found to be reduced between T0 and T1, as well as between T0 and T2 (F=13.712; P=0.0001), with no differences between groups (F=1.724; P=0.191). VAS at motion revealed a significant "group × time-check" interaction (F=2.491; P=0.032), with increasing effect of time on VAS reduction (F=17.748; P=0.0001). This was most pronounced in the experimental group at 8 weeks (F=3.437; P=0.045). The Lequesne Index showed reductions at T1 and T2 compared to T0 (F=9.535; P=0.0001), along with group effect, since the experimental group presented a lower score at T2 (F=7.091; P=0.009). No significant changes were found in the knee ROM and inflammation markers. CONCLUSION CartiJoint Forte, added to physical therapy, may ameliorate pain and help to improve algofunctional score in knee OA patients. CLINICAL REHABILITATION IMPACT Treatment of knee OA with curcuminoids plus glycosaminoglycans, added to physical therapy, improves VAS at motion and Lequesne Index scores.

Abstract
The paper presents the study of the excretion of sulfated glycosaminoglycans (GAG) in the urine of rats in experimental hemorrhagic cystitis induced by cyclophosphamide and treated with glycosaminoglycan replacement therapy. Rats were given intraperitoneal injections of cyclophosphamide at a dose of 100 mg per 1 kg body weight and subsequently treated with intragastric administration of the combined preparation of glycosaminoglycans containing glucosamine hydrochloride and chondroitin sulfate at a dose of 10 and 100 mg per 1 kg of body weight. Within 24 or 72 hours after cystitis induction there was a statistically significant increase in urinary GAG excretion. The study also found a decrease (from 1.34 to 1.22 mg/dL) in urinary GAG within 0 to 72 hours following induction of acute cystitis without glycosaminoglycan therapy. In the subchronic model of inflammation in the bladder, upon repeated administration of low doses of cyclophosphamide (50 mg/kg), decrease in urinary GAG within 0 to 72 hours (1,32±0,13 mg/dL) as well as increased excretion after 96 hours at a concentration of 2,29±0,13 mg/L after initiation cystitis were found.

Abstract
BACKGROUND Glucosamine and chondroitin are popular non-vitamin dietary supplements used for osteoarthritis. Long-term use is associated with lower incidence of colorectal and lung cancers and with lower mortality; however, the mechanism underlying these observations is unknown. In vitro and animal studies show that glucosamine and chondroitin inhibit NF-kB, a central mediator of inflammation, but no definitive trials have been done in healthy humans. METHODS We conducted a randomized, double-blind, placebo-controlled, cross-over study to assess the effects of glucosamine hydrochloride (1500 mg/d) plus chondroitin sulfate (1200 mg/d) for 28 days compared to placebo in 18 (9 men, 9 women) healthy, overweight (body mass index 25.0-32.5 kg/m2) adults, aged 20-55 y. We examined 4 serum inflammatory biomarkers: C-reactive protein (CRP), interleukin 6, and soluble tumor necrosis factor receptors I and II; a urinary inflammation biomarker: prostaglandin E2-metabolite; and a urinary oxidative stress biomarker: F2-isoprostane. Plasma proteomics on an antibody array was performed to explore other pathways modulated by glucosamine and chondroitin. RESULTS Serum CRP concentrations were 23% lower after glucosamine and chondroitin compared to placebo (P = 0.048). There were no significant differences in other biomarkers. In the proteomics analyses, several pathways were significantly different between the interventions after Bonferroni correction, the most significant being a reduction in the "cytokine activity" pathway (P = 2.6 x 10-16), after glucosamine and chondroitin compared to placebo. CONCLUSION Glucosamine and chondroitin supplementation may lower systemic inflammation and alter other pathways in healthy, overweight individuals. This study adds evidence for potential mechanisms supporting epidemiologic findings that glucosamine and chondroitin are associated with reduced risk of lung and colorectal cancer.

Abstract
Cigarette smoking causes persistent lung inflammation that is mainly regulated by redox-sensitive pathways. We have reported that cigarette smoke (CS) activates a NADPH oxidase-dependent reactive oxygen species (ROS)-sensitive AMP-activated protein kinase (AMPK) signaling pathway leading to induction of lung inflammation. Glucosamine, a dietary supplement used to treat osteoarthritis, has antioxidant and anti-inflammatory properties. However, whether glucosamine has similar beneficial effects against CS-induced lung inflammation remains unclear. Using a murine model we show that chronic CS exposure for 4 weeks increased lung levels of 4-hydroxynonenal (an oxidative stress biomarker), phospho-AMPK, and macrophage inflammatory protein 2 and induced lung inflammation; all of these CS-induced events were suppressed by chronic treatment with glucosamine. Using human bronchial epithelial cells, we demonstrate that cigarette smoke extract (CSE) sequentially activated NADPH oxidase; increased intracellular levels of ROS; activated AMPK, mitogen-activated protein kinases (MAPKs), nuclear factor-κB (NF-κB), and signal transducer and activator of transcription proteins 3 (STAT3); and induced interleukin-8 (IL-8). Additionally, using a ROS scavenger, a siRNA that targets AMPK, and various pharmacological inhibitors, we identified the signaling cascade that leads to induction of IL-8 by CSE. All these CSE-induced events were inhibited by glucosamine pretreatment. Our findings suggest a novel role for glucosamine in alleviating the oxidative stress and lung inflammation induced by chronic CS exposure in vivo and in suppressing the CSE-induced IL-8 in vitro by inhibiting both the ROS-sensitive NADPH oxidase/AMPK/MAPK signaling pathway and the downstream transcriptional factors NF-κB and STAT3.

Abstract
A comparison of the relative bioavailability and intensity of penetration of glucosamine sulfate in oral, injection and topical administration of the dosage form Hondroxid Maximum as a cream containing micellar system for transdermal delivery of glucosamine in the experiment by Sprague-Dawley rats was carried out. On the base on the pharmacokinetic profiles data of glucosamine in rat blood plasma with daily administration in 3 times a day for 1 week by cream Hondroxid Maximum 400 mg/kg and the single injection solution of 4% Glucosamine sulfate 400 mg/kg was found that the relative bioavailability was 61.6%. Calculated penetration rate of glucosamine in the plasma through the rats skin in 4 hours, equal to 26.9 μg/cm2 x h, and the penetration of glucosamine through the skin into the plasma after a single dose of cream in 4 hours was 4.12%. Comparative analysis of literature and experimental data and calculations based on them suggest that medicine Hondroxid Maximum, cream with transdermal glucosamine complex in the treatment in accordance with the instructions can provide an average concentration of glucosamine in the synovial fluid of an inflamed joint in the range (0.7 - 1.5) μg/ml, much higher than the concentration of endogenous glucosamine human synovial joint fluid (0.02 - 0.07 μg/ml). By theoretical calculations taking into account experimental data it is shown that the medicine Hondroxid Maximum can reach the bioavailability level of the modern injection forms and exceed the bioavailability level of modern oral forms of glucosamine up to 2 times.

Abstract
BACKGROUND The purpose of this study was to assess the effect of 8-weeks ingestion of a commercialized joint pain dietary supplement (Instaflex™ Joint Support, Direct Digital, Charlotte, NC) compared to placebo on joint pain, stiffness, and function in adults with self-reported joint pain. Instaflex™ is a joint pain supplement containing glucosamine sulfate, methylsufonlylmethane (MSM), white willow bark extract (15% salicin), ginger root concentrate, boswella serrata extract (65% boswellic acid), turmeric root extract, cayenne, and hyaluronic acid. METHODS Subjects included 100 men and women, ages 50-75 years, with a history (>3 months) of joint pain, and were randomized to Instaflex™ or placebo (3 colored gel capsules per day for 8 weeks, double-blind administration). Subjects agreed to avoid the use of non-steroidal anti-inflammatory drugs (NSAID) and all other medications and supplements targeted for joint pain. Primary outcome measures were obtained pre- and post-study and included joint pain severity, stiffness, and function (Western Ontario and McMaster Universities [WOMAC]), and secondary outcome measures included health-related quality of life (Short Form 36 or SF-36), systemic inflammation (serum C-reactive protein and 9 plasma cytokines), and physical function (6-minute walk test). Joint pain symptom severity was assessed bi-weekly using a 12-point Likert visual scale (12-VS). RESULTS Joint pain severity was significantly reduced in Instaflex™ compared to placebo (8-week WOMAC, ↓37% versus ↓16%, respectively, interaction effect P = 0.025), with group differences using the 12-VS emerging by week 4 of the study (interaction effect, P = 0.0125). Improvements in ability to perform daily activities and stiffness scores in Instaflex™ compared to placebo were most evident for the 74% of subjects reporting knee pain (8-week WOMAC function score, ↓39% versus ↓14%, respectively, interaction effect P = 0.027; stiffness score, ↓30% versus ↓12%, respectively, interaction effect P = 0.081). Patterns of change in SF-36, systemic inflammation biomarkers, and the 6-minute walk test did not differ significantly between groups during the 8-week study CONCLUSIONS Results from this randomized, double blind, placebo-controlled community trial support the use of the Instaflex™ dietary supplement in alleviating joint pain severity in middle-aged and older adults, with mitigation of difficulty performing daily activities most apparent in subjects with knee pain.

Abstract
Impaired glucose tolerance and type 2 diabetes in rodents are associated with increased islet blood flow. If this is important for modulation of the endocrine function is at present unknown. We evaluated if glucosamine infusion, which induces peripheral insulin resistance and glucose intolerance, could be used to acutely increase islet blood flow. We infused anaesthetized Sprague-Dawley rats for 2 h with glucosamine (6 mg/kg body weight), in some cases followed by glucose administration. The former induced a 2-fold increase in serum insulin concentrations while plasma glucose remained unchanged. In vitro an augmented insulin response to hyperglycemia and decreased insulin content in batch type islet incubations with glucosamine for 24 h were seen. After 2 h glucosamine exposure in vitro, insulin release was decreased. In vivo glucosamine infusion increased islet blood flow, without affecting other regional blood flow values. Glucose increased islet blood flow to the same extent in control and glucosamine-infused rats. When exposed to 10 mmol/L glucosamine arterioles of isolated perfused islets showed a 10% dilation of their vascular smooth muscle. Thus, application of this model leads to acute hyperinsulinemia in vivo but a decreased insulin release in vitro, which suggests that effects not located to β cells are responsible for the effects seen in vivo. An increased islet blood flow in previously healthy animals was also seen after glucose administration, which can be used to further dissect the importance of blood flow changes in islet function.

Abstract
Gastrointestinal or cardiovascular complications limit nonsteroidal anti-inflammatory drugs (NSAID) prescription. Glucosamine hydrochloride (GS-HCl) alternatively chosen, but debates still exist in its clinical efficiency. COX-2 instability through inhibiting COX-2 N-glycosylation of GS-HCl raised the possibility of NSAID sparing effect. Study was done to determine whether combination treatment of glucosamine and NSAID contributes to gastric safety through NSAID sparing effect. IEC-6 cells were stimulated with TNF-α and compared the expressions of inflammatory mediators after indomethacin alone or combination of indomethacin and GS-HCl by Western blotting and RT-PCR. C57BL/6 mice injected with type II collagen to induce arthritis were treated with indomethacin alone or combination of reduced dose of indomethacin and GS-HCl after 3 weeks. TNF-α increased the expression of COX-2, iNOS and inflammatory cytokines, but GS-HCl significantly attenuated TNF-α-induced COX-2 expression. Decreased COX-2 after GS-HCl was caused by N-glycosylation inhibition as much as tunicamycin. Combination of reduced dose of indomethacin and GS-HCl significantly reduced the expressions of ICAM-1, VCAM-1, IL-8, IL-1β, MMP-2, MMP-7, MMP-9, and MMP-11 mRNA as well as NF-κB activation better than high dose indomethacin alone. These NSAID sparing effect of GS-HCl was further proven in collagen-induced arthritis model. Combination of GS-HCl and 2.5 mg/kg indomethacin showed significant protection from gastric damages as well as efficacious anti-arthritic effect. Taken together, COX-2 N-glycosylation inhibition by GS-HCl led to indomethacin sparing effects, based on which combination of GS-HCl and reduced dose of NSAID can provide the strategy to secure stomach from NSAID-induced gastric damage as well as excellent anti-arthritic effects.

Abstract
PURPOSE Glucosamine and chondroitin are non-vitamin, non-mineral supplements which have anti-inflammatory properties. These supplements are typically used for joint pain and osteoarthritis and are commonly taken as either glucosamine alone or glucosamine plus chondroitin. An exploratory analysis conducted within the VITamins And Lifestyle (VITAL) study observed any use of glucosamine and chondroitin to be associated with reduced risk of colorectal cancer (CRC) after 5 years of follow-up. METHODS With two additional years of follow-up, we have studied these associations in greater depth, including associations by frequency/duration of use and by formulation, and have evaluated whether observed associations are modified by factors associated with inflammation. Participants include 75,137 western Washington residents aged 50-76 who completed the mailed VITAL questionnaire between 2000 and 2002. Use of glucosamine and chondroitin was ascertained by questions about supplement use during the 10-year period prior to baseline, and participants were followed for CRC through 2008 (n = 557). Cox regression was used to estimate hazard ratios (HRs) and 95 % confidence intervals (CIs). RESULTS Persons reporting use of glucosamine + chondroitin on 4+ days/week for 3+ years had a non-statistically significant 45 % lower CRC risk than non-users (HR: 0.55; 95 % CI 0.30-1.01; p-trend: 0.16). This association varied by body mass index (p-interaction: 0.006), with inverse association observed among the overweight/obese (p-trend: 0.02), but not among the underweight/normal weight. Use of glucosamine alone was not significantly associated with CRC risk. CONCLUSIONS There is great need to identify safe and effective cancer preventive strategies, suggesting that glucosamine and chondroitin may merit further attention as a potential chemopreventive agent.

Abstract
The aim of this paper was to provide an overview of the current knowledge and understanding of the potential beneficial physiological effects of glucosamine (GlcN) on joint health. The objective was to reach a consensus on four critical questions and to provide recommendations for future research priorities. To this end, nine scientists from Europe and the United States were selected according to their expertise in this particular field and were invited to participate in the Hohenheim conference held in August 2011. Each expert was asked to address a question that had previously been posed by the chairman of the conference. Based on a systematic review of the literature and the collection of recent data, the experts documented the effects of GlcN on cartilage ageing, metabolic/kinetic and maintenance of joint health as well as reduction of risk of OA development. After extensive debate and discussion the expert panel addressed each question and a general consensus statement was developed, agreeing on the current state-of-the-art and future areas for basic and clinical studies. This paper summarizes the available evidence for beneficial effects of GlcN on joint health and proposes new insight into the design of future clinical trials aimed at identifying beneficial physiological effect of GlcN on joint tissues.

Abstract
UNLABELLED Pain is one of the major symptoms of the osteoarthritis (OA). The objective of the study was to evaluate impact of combined therapy with diclofenac, aescin and original glucosamine sulfate on pain severity in patients with OA of different localizations in real life clinical settings in Russia and Ukraine. METHODS Design--prospective, non-controlled, before and after post-marketing study. Study was performed in 38 cities across Russia and Ukraine in 2012. Registered anti-inflammatory and symptomatic slow acting drugs were used according to the registered indications and dosages. In Russian sites combined therapy A using diclofenac ("Dorosan" formulation, Rottapharm S.p.A., aerosole 1%, 3-4 times/day) for two weeks, original glucosamine sulfate ("Dona" formulation, Rottapharm S.p.A.) intramuscular (ampule 200 mg/ml, 2 ml 3 times/week) for 4 weeks and per os (powder 1500 mg, once/day) for 8 weeks was used. In Ukraine sites (scheme B) diclofenac was substituted with topical aescin ("Reparil-Gel" formulation, Madaus AG, tube 400 mg, 2-3 times/day) anti-inflammatory product. Physicians were free to change therapy and study organizers had no impact on prescribing and management practice. Patients with OA of different localizations were included into the study. Pain severity was assessed using numeric rating scale. Total duration of the study was 8 weeks. Questionnaires were distributed to patients via physician out-patient offices. The only endpoint was the difference in median pain severity at the end of the study compared with the baseline level. RESULTS In total 4931 patients were included into the study (mean age 57 +/- 12 years, 75% were females). Scheme A was used in 3956 patients and scheme B in 975 patients. The median pain severity decreased from 0.7 at the baseline (interquartile range +/- 0.2) to 0.2 (interquartile range +/- 0.2) after 8 weeks of the study in both treatment regimens (p < 0.001). Limitations of the study include absence of the control group, collection of the questionnaires from physician offices, rather than directly from patients, limited range of clinical data collected and use of single instrument to assess pain severity. CONCLUSIONS Post-marketing study of combined therapy of OA of different localizations using diclofenac, aescin and original glucosamine sulfate in Russia and Ukraine demonstrated decrease of the pain severity, assessed by numeric rating scale, after 8 weeks of the treatment.

Abstract
D-Glucosamine hydrochloride (GlcN∙HCl) is an endogenous amino monosaccharide synthesized from glucose that is useful in the treatment of joint diseases in both humans and animals. The aim of this study was to examine amino acid metabolism in dogs after oral administration of GlcN∙HCl. Accelerated fumarate respiration and elevated plasma levels of lactic acid and alanine were observed after administration. These results suggest that oral administration of GlcN∙HCl induces anaerobic respiration and starvation in cells, and we hypothesize that these conditions promote cartilage regeneration. Further studies are required to evaluate the expression of transforming growth factor-beta (TGF-β).

Abstract
Glucosamine and chondroitin are products commonly used by older adults in the US and Europe. There is limited evidence that they have anti-inflammatory properties, which could provide risk reduction of several diseases. However, data on their long-term health effects is lacking. To evaluate whether use of glucosamine and chondroitin are associated with cause-specific and total mortality. Participants (n = 77,510) were members of a cohort study of Washington State (US) residents aged 50-76 years who entered the cohort in 2000-2002 by completing a baseline questionnaire that included questions on glucosamine and chondroitin use. Participants were followed for mortality through 2008 (n = 5,362 deaths). Hazard ratios (HR) for death adjusted for multiple covariates were estimated using Cox models. Current (baseline) glucosamine and chondroitin use were associated with a decreased risk of total mortality compared to never use. The adjusted HR associated with current use of glucosamine (with or without chondroitin) was 0.82 (95 % CI 0.75-0.90) and 0.86 (95 % CI 0.78-0.96) for chondroitin (included in two-thirds of glucosamine supplements). Current use of glucosamine was associated with a significant decreased risk of death from cancer (HR 0.87 95 % CI 0.76-0.98) and with a large risk reduction for death from respiratory diseases (HR 0.59 95 % CI 0.41-0.83). Use of glucosamine with or without chondroitin was associated with reduced total mortality and with reductions of several broad causes of death. Although bias cannot be ruled out, these results suggest that glucosamine may provide some mortality benefit.

Abstract
Present work was inspired by an interesting finding of Raithel et al. (11) about remission of steroid-dependent, chronically active ulcerative colitis (UC) in a patient, after treatment with a combination of fexofenadine, disodium cromoglycate and an amino acid-based formula. Literature reports involvement of mast cells activation and increased histamine secretion in the pathogenesis of colitis. The purpose of present work was to evaluate the potential of a novel prodrug of fexofenadine in 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis in rats. A colon-specific mutual amide prodrug of fexofenadine with D-glucosamine was synthesized. Release was studied in tissue homogenates and rat fecal matter by HPLC. It was further screened in TNBS-induced colitis in rats and also for adverse effects on rat liver, stomach and pancreas. The spectral analysis confirmed the structure of the prodrug. Highly hydrophilic prodrug enabled efficient delivery of fexofenadine to colon. Prodrug furnished negligible release of fexofenadine in upper gastrointestinal tract (GIT) homogenates. About 82% release of fexofenadine was observed in rat fecal matter at the end of 12 hours. The prodrug was twice as effective in lowering the quantifying parameters of colonic inflammation in TNBS- induced colitis than fexofenadine, D-glucosamine, their physical mixture and interestingly oral 5-amino salicylic acid while 2.7 times less effective than sulfasalazine. The prodrug restored disrupted colonic architecture to normal without adversely affecting stomach, liver and pancreas. In conclusion, the results support histamine involvement in the pathogenesis of UC. This novel, dual acting colon-specific prodrug of fexofenadine is promising as combination maintenance therapy with sulfasalazine for UC.

Abstract
OBJECTIVES There has been a dramatic increase in the use of complementary medicines over recent decades. Glucosamine is one of the most commonly used complementary medicines in Western societies. An understanding of glucosamine consumption is of significance for public health and future health promotion. This paper, drawing upon the largest dataset to date with regards to glucosamine use (n = 266,844), examines the use and users of glucosamine amongst a sample of older Australians. DESIGN Analysis of the self-reported data on use of glucosamine, demographics and health status as extracted from the dataset of the 45 and Up Study, which is the largest study of healthy ageing ever undertaken in the Southern Hemisphere involving over 265,000 participants aged 45 and over. RESULTS Analysis reveals that 58,630 (22.0%) participants reported using glucosamine in the 4 weeks prior to the survey. Use was higher for those who were female, non-smokers, residing in inner/outer regional areas, with higher income and private health insurance. Of all the health conditions examined only osteoarthritis was positively associated with use of glucosamine, while cancer, heart attack or angina and other heart disease were all negatively associated with glucosamine use. CONCLUSIONS This study suggests that a considerable proportion of the Australia population aged 45 and over consume glucosamine. There is a need for health care practitioners to enquire with their patients about their use of glucosamine and for further attention to be directed to providing good quality information for patients and providers with regards to glucosamine products.

Abstract
Glucosamine is a popular treatment for osteoarthritis. Despite of the ongoing debate around its efficiency, the sale of glucosamine is a success in pharmacies. The molecule remains issue of controversy: while some studies provide proof of its efficiency, other studies and meta-analysis are unable to answer the question or don't find any advantage. This article treats the current state of glucosamine regarding its efficiency and safety and aims to trigger the pharmacy-team to help the patient evaluating the product after three months of use.

Abstract
BACKGROUND Osteoarthritis (OA) is the most common form of arthritis of the temporomandibular joint (TMJ), and can often lead to severe pain in the orofacial region. Management options for TMJ OA include reassurance, occlusal appliances, physical therapy, medication in addition to several surgical modalities. OBJECTIVES To investigate the effects of different surgical and non-surgical therapeutic options for the management of TMJ OA in adult patients. SEARCH METHODS We searched the following databases: the Cochrane Oral Health Group Trials Register (to 26 September 2011); CENTRAL (The Cochrane Library 2011, Issue 3); MEDLINE via OVID (1950 to 26 September 2011); EMBASE via OVID (1980 to 26 September 2011); and PEDro (1929 to 26 September 2011). There were no language restrictions. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing any form of non-surgical or surgical therapy for TMJ OA in adults over the age of 18 with clinical and/or radiological diagnosis of TMJ OA according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) guideline or compatible criteria.Primary outcomes considered were pain/tenderness/discomfort in the TMJs or jaw muscles, self assessed range of mandibular movement and TMJ sounds. Secondary outcomes included the measurement of quality of life or patient satisfaction evaluated with a validated questionnaire, morphological changes of the TMJs assessed by imaging, TMJ sounds assessed by auscultation and any adverse effects. DATA COLLECTION AND ANALYSIS Two review authors screened and extracted information and data from, and independently assessed the risk of bias in the included trials. MAIN RESULTS Although three RCTs were included in this review, pooling of data in a meta-analysis was not possible due to wide clinical diversity between the studies. The reports indicate a not dissimilar degree of effectiveness with intra-articular injections consisting of either sodium hyaluronate or corticosteroid preparations, and an equivalent pain reduction with diclofenac sodium as compared with occlusal splints. Glucosamine appeared to be just as effective as ibuprofen for the management of TMJ OA. AUTHORS' CONCLUSIONS In view of the paucity of high level evidence for the effectiveness of interventions for the management of TMJ OA, small parallel group RCTs which include participants with a clear diagnosis of TMJ OA should be encouraged and especially studies evaluating some of the possible surgical interventions.

Abstract
The experience of 10 year application of the preparation dona - glucosamine sulphate (Sachet) Rottapharm, Italy among the children age group during the conservative treatment of thighbone head osteochondropathy (Pertes disease) at the Tbilisi, Children's Sanatorium "Gazapkhuli" orthopedic department is described in the article. In the article, it is mentioned the great importance of glicosaminglycans (GAG) in the matter of formation and existence of connective tissue, their greatest role in the metabolism of bone and cartilaginoid tissue, the considerable importance of preparation dona components (glucosamine, sulphate group) in biochemical processes that proceeds in cartilaginoid tissue - in the gialuroni acid and glicosaminglycans synthesis (the substances that the proteoglycans are composed of). The experience that the Department has in the application of polysulphate glicosaminglycan - preparation rumalon (Russia), during the conservative treatment of Pertes disease, is mentioned. Taking into account the afore-mentioned, the preparation dona was introduced into the scheme of conservative treatment of 300 child patients within 5-14 age group having different stages of Pertes disease. During 5-6 years after the treatment cessation, observation on children patients showed that during the lasting treatment period with the preparation, the hypersensitivity, negative circumstances and complications were not observed. The positive results of the treatments (90-92%), structural restoration processes both in bone and cartilaginoid tissue after the intake of roentgenologically approved preparation, gives the basis for the author of the article to express its opinion on the possibility of application of preparation dona - glucosamine sulphate (Sachet)-1500, as a structural-modified preparation, during the complex conservative treatment of Pertes disease among children within 5-14 age group.

Abstract
OBJECTIVES To determine patterns of supplement use in a UK community-dwelling older population, and to investigate the extent to which supplement user groups differ, in terms of their sociodemographic and lifestyle characteristics, diet and morbidity. DESIGN Cross-sectional cohort study. SETTING Home interview and clinic visit. PARTICIPANTS 3217 Hertfordshire Cohort Study participants, aged 59 to 73. MEASUREMENTS Information was obtained on the participant's social and medical history by a trained research nurse. Diet over the preceding 3 months was assessed by Food Frequency Questionnaire; compliance with 'healthy' eating recommendations was defined using individual scores for a 'prudent' dietary pattern, identified using principal components analysis. Details of all dietary supplements taken in the preceding 3 months were recorded. Individual supplements were allocated to one of 10 types based on their nutrient composition. Cluster analysis was used to define groups of supplement users. RESULTS 45.4% of men and 57.5% of women reported taking at least one dietary supplement in the previous 3 month period. There were 5 distinct clusters of supplement users; these were common to men and women. They were labelled according to the principal supplement taken; oils, glucosamine, single vitamins, vitamins and minerals, and herbal products. These groups differed in their social class and prudent diet score, but few other characteristics. With the exception of a difference in diagnosis of diabetes among the women, there were no differences in morbidity between the supplement groups in either men or women. CONCLUSIONS Dietary supplement use is high in this population. There are distinct patterns of supplement use, which are related to sociodemographic and lifestyle characteristics including diet, though there were few clear differences in morbidity.

Abstract
OBJECTIVES This study seeks to demonstrate the influence of pharmacological substances from the SYSADOA group on the progression of osteoarthritis in the human knee. The quantification methods were direct measurement of the rheological properties of the knee joints in vivo and standard WOMAC index questionnaires. MATERIALS AND METHODS The drugs were administered orally to 34 probands with second degree gonarthrosis for 13 weeks. The untreated control group consisted of 10 probands. The rheological properties of the joints were determined by a biorheometer, and subjective assessment of the knees by patients (WOMAC) before and after medication, and for a further 13 weeks. Changes in the calculated parameters over time were compared. RESULTS During the audited perioda slight deterioration in all of the parameters was observed in the untreated group. The treated group, however, improved in all the parameters and some indicators showed statistically significant differences. The positive effects of the SYSADOA persisted for 3 months after the end of treatments. Partial correlation was found between the results of the WOMAC questionnaire and the rheological measurements. CONCLUSIONS This study shows the positive effects of the preparation on arthritic changes in the knee joint, but due to the large variance of the collected data, this conclusion is on the borderline of statistical significance. The method of measuring the rheological properties of the joints is suitable for evaluating the progression of OA.

Abstract
This study was carried out to prove the possibility of inhibition of long bones epiphyseal plates activity with photodynamic impact. Comparative analysis of the Chlorin E6 accumulation with transcutaneous and intraperitoneal administration mode, carried out on 175 laboratory mice showed the drug accumulates selectively in the epiphyseal plates of long bones, regardless of the mode of administration. 15 mice (males and females) at the age of active grownig were subjected to the single laser radiation impact on the knee joints area: 5 ones with transcutaneous Chlorine E6 administration, another 5 ones with intraperitoneal administration and the rest 5 without the drug. Histological samples of 15 experimental mice epiphyseal plates were examined by light microscopy, compared with 10 intact control mice. Influence of the laser radiation without administration of Chlorin E6 leads to intracellular swelling of epiphyseal plates chondrocytes. Influence of the laser radiation after transcutaneous or intraperitoneal injection of Chlorine E6 reduces significantly the total number of epiphyseal plates chondrocytes, without reducing the proportion of terminally-differentiated chondrocytes. Thus, the photodynamic impact inhibits the activity of epiphyseal plates of the mice.

Abstract
OBJECTIVES To evaluate, using musculoskeletal ultrasound (MSUS), the effects of Etanercept therapy in patients with rheumatoid arthritis (RA) over 3 months of treatment. METHODS Eighteen consecutive patients, 3 male and 15 female, affected by RA (ACR criteria) who were non-responders or partial responders to DMARDs therapy were commenced on Etanercept treatment. MSUS was performed bilaterally in the 2nd and 5th metacarpophalangeal, 3rd interphalangeal, wrist and knee joints, using a Philips/HP Image Point HX machine with a 7,5 MHz linear probe for knee joints and a 14 MHz probe for the hands and wrists. In addition, power Doppler was used with the following settings: PRF 700-1000Hz, gain 60-65 dB, low filter. For all the changes a semi-quantitative score (0-3) was used to indicate the presence of a localised inflammatory process (synovitis, tenosynovitis). An overall score was then calculated based on the sum of the single scores in order to obtain a comprehensive score indicative of the global pathological change. RESULTS The overall score significantly (p<10-5) reduced between T0 (8,5) and T3 (5). Even the most part of the local joint scores significantly reduced. CONCLUSIONS A positive response to treatment with Etanercept was demonstrated by MSUS examination of several joints. The results of our study are supportive of those presented in other reports where MSUS was used to monitor disease activity. We were able however to demonstrate this in a wider range of anatomical targets than in previous studies. MSUS is a useful tool in the monitoring of biologic therapy in RA.

Abstract
OBJECTIVE Inflammation plays an important role in lung carcinogenesis. Epidemiologic studies have reported inverse associations of non-steroidal anti-inflammatory drug (NSAID) use and lung cancer risk. Previously, we found that ever use of glucosamine and chondroitin, which have anti-inflammatory properties, were inversely associated with lung cancer risk. After an additional year of follow-up, we further examined the association including frequency/duration of use, interaction with factors associated with inflammation, and lung cancer histology. METHODS Participants were members of the VITamins And Lifestyle cohort. Adults, aged 50-76 years, who were residents of western Washington State, completed a baseline questionnaire in 2000-2002 (n = 76,904). Participants were queried on their use of glucosamine and chondroitin, over the 10 years prior to baseline, and categorized as nonuser, low use < 4 days/week or < 3 years, or high use ≥ 4 days/week and ≥ 3 years. Lung cancer cases (n = 808) were ascertained through linkage to the Surveillance, Epidemiology, and End Results cancer registry. RESULTS High 10-year use of glucosamine [hazard ratio (HR), 0.77; 95% CI: 0.56-1.07; p trend = 0.04] but not chondroitin was associated with a reduction in lung cancer risk. The association with glucosamine was limited to adenocarcinoma (HR, 0.49; 95% CI: 0.27-0.90; p trend <0.01) and was not modified by NSAID use or smoking status. CONCLUSIONS Our results for glucosamine use are similar to the prior human studies of NSAID use and lung cancer, both in magnitude and the limitation of the association to adenocarcinoma. Unlike NSAIDs, glucosamine has no known adverse effects. Although confirmatory studies are needed, glucosamine is an attractive candidate for lung cancer chemoprevention.

This study describes dietary supplement consumption practices among the Taiwanese population over the age of 65. Data for the analyses were derived from the 2005-2008 Nutrition and Health Survey in Taiwan. Data from a total of 914 participants (456 men and 458 women) was collected in the study to delineate patterns of supplement usage. The results indicated that the percentage of individuals taking supplements was 45.7% for men and 52.2% for women. There were no significant differences in supplement use by gender, age group, geographic stratum, current employment status, household monthly income, self-reported health status or marital status, except for higher education and adequate perceived financial resources. Half of both men and women chose to take only one supplement. In addition, as the number of supplements taken increased, the number of people decreased. The elderly with higher education levels were more likely to take two kinds of supplements. The top five supplements consumed from highest to lowest were: glucosamine, multivitamins and minerals, calcium, fish oil and vitamin B complex. The major reason for supplements use for men was to supplement an unbalanced diet, and that for women was to prevent joint degeneration. The main factor influencing choice of supplements in the elderly was receiving the supplement as a gift from another person. Note that mean intakes of vitamins A, C, E, B-1, B-2, B-6, B-12, biotin, niacin, and pantothenic acid from supplements over-exceeded DRIs in Taiwan.

Abstract
Glucosamine (GlcN) is a widely utilized dietary supplement that is used to promote joint health. Reports that oral GlcN supplementation at usual doses adversely affects glucose metabolism in subjects with impaired glucose tolerance have raised concerns that GlcN should be contraindicated in individuals with diabetes and those at risk for developing it. This review addresses its potential, when used at typical doses, to affect glucose metabolism and insulin sensitivity in healthy individuals and those with diabetes or 'pre-diabetes'. Publicly available scientific information and data on GlcN were systematically compiled using the electronic search tool, Dialog , and reviewed with special emphasis on human studies. In long-term clinical trials, including those containing subjects with type 2 diabetes or 'pre-diabetes', GlcN produced a non-significant lowering of fasting blood glucose concentrations in all groups of subjects treated for periods of up to 3 years. Owing to limitations in study design, conclusions based on studies that report adverse affects of GlcN on insulin sensitivity and glucose tolerance in pre-diabetic subjects are suspect. However, no definitive long-term studies of GlcN use for individuals with pre-diabetes are available. Nevertheless, based on available evidence, we conclude that GlcN has no effect on fasting blood glucose levels, glucose metabolism, or insulin sensitivity at any oral dose level in healthy subjects, individuals with diabetes, or those with impaired glucose tolerance.

Abstract
REASONS FOR PERFORMING STUDY Oral chondroprotective supplements are commercially popular for veteran (and other athletic or arthritic) horses prone to joint degeneration, yet lack conclusive scientific support. OBJECTIVES To quantify the effects of an oral joint supplement (combination glucosamine hydrochloride (GHCL), chondroitin sulphate (CS) and N-acetyl-D-glucosamine) in vivo on stride parameters of veteran horses. METHODS Twenty veteran horses were randomly assigned to a treatment (n = 15) or placebo group (n = 5). Pre-treatment gait characteristics were recorded at trot using digital video footage (50 Hz). The range of joint motion, stride length, and swing and stance duration were assessed using 2-dimensional motion analysis. Treatment (or placebo) was administered daily for 12 weeks at the manufacturer's recommended dosage. Gait was reassessed every 4 weeks using the pre-treatment protocol. Double blind procedure was implemented throughout. Relationships between variables were analysed using General Linear Model. RESULTS Differences occurred in the treated horses by week 8. Range of joint motion increased significantly in the elbow (P<0.05), stifle and hind fetlock (P<0.01). Stride length increased significantly (P<0.05) with treatment. Swing duration was significantly increased at week 12 (P<0.05), whilst stance duration remained constant. CONCLUSION The oral chondroprotective offered symptomatic relief to veteran horses, evidenced by improved stride characteristics. POTENTIAL RELEVANCE Oral GHCL and CS supplementation may improve welfare by alleviating symptoms of degenerative joint disease.
