ObjectiveBiomarkers of adipose tissue may affect glucose and lipid metabolism and present pro-inflammatory properties, thus could be involved in the pathobiochemistry of cardiovascular disease (CVD). The coexistence of sleep apnea syndrome (OSA) and metabolic risk factors of CVD is worth explaining. The aim of the study was to compare the serum adipocytokines in subjects with and without OSA, who had all elevated body mass index (BMI).MethodsOverweight (BMI: 25.0-29.9 kg/m2) and obese (BMI: 30.0-39.9 kg/m2) OSA-suspected Caucasian males, aged 30-63, with no acute disease or chronic disorder underwent polysomnographic evaluation to select OSA-positive (AHI ≥ 5) and OSA-negative (AHI < 5) subjects. Four subgroups were created of 18 persons each: Over(weight)-OSA-Neg, Over-OSA-Pos, Obese-OSA-Neg, Obese-OSA-Pos. In all subjects, plasma carbohydrate and lipid metabolism parameters, and serum uric acid, resistin and leptin concentrations were determined.ResultsA decreased resistin level was observed in Over-OSA-Pos vs. Over-OSA-Neg subjects (P = 0.037) as well as in Obese-OSA-Pos vs. Obese-OSA-Neg (P = 0.045). No differences in leptin concentrations were observed. A positive correlation between leptin and BMI was in both overweight subgroups and a negative one between resistin and fasting glucose was in both obese subgroups.ConclusionsOSA may decrease the serum resistin level in subjects with excess body mass and also may contribute to glucose metabolism, but has no influence on the leptin level.
638the postsynaptic area was increased. However, future morphometric study based on a series of fibromyalgia patients is indispensable to rule out the possibility of a sampling error. Unfortunately, studies of endplate ultrastructure are hindered by methodological problems (8). Most importantly, the small size of the zone of the muscle containing endplates and the dimensions of ultra-thin sections relative to those of the endplate zone markedly decrease the chances to locate endplates with an electron microscope. Therefore, endplates are only exceptionally observed in muscle embedded for electron microscopy from routine limb muscle biopsies. In humans, endplate morphology was studied in most instances using specimens from the small intercostal muscle. For ethical reasons, such muscle specimens are not available from fibromyalgia patients. Therefore, we had to compare endplates from different muscles. This limits the reliability of our data. However, Slater et al. observed no difference in the endplate ultrastructure between these two muscles (9).
Background. This study aimed to provide clinical information on general and joint performance from individuals taking Tregocel® (containing curcuminoid and extracts of the herbs Harpagophytum procumbens, Boswellia serrata, Apium graveolens, and Zingiber officinale) alongside a standard therapy of symptomatic mild knee osteoarthritis (OA). Methods. This was a multicenter, open-label, prospective, single-arm study, in which Tregocel® was supplemented for 36 weeks. Participants with symptomatic mild knee OA requiring pharmacologic treatment for pain were enrolled. Physical performance (6-minute walk test, WOMAC-pain and functional domain, and heel-thigh distance flexion test), general performance (WOMAC questionnaire), and VAS (Visual Analogue Scale) assessment of knee pain, as well as anti-inflammatory and analgesic medication consumption, were assessed. Results. Between January and April 2019, 107 participants were enrolled and analysed in per protocol population. Mean age was 59.7 (SD 10.8) years, and there were 68.2% women. Mean observation time was 291.1 (SD 7.7) days. Mean increase in 6MWT result observed at the end of the study was 26.0 (SD 30.4) m ( p < 0.001 ). Median VAS score decreased from 60.0 (IQR 50–72) mm at the beginning of the study to 21.0 (IQR 14–30) mm after 36 weeks of product administration ( p < 0.001 ). Regular knee OA medications were taken in 99.1% of subjects at baseline decreasing to 55.1% at the end of the Tregocel® supplementation. Conclusions. During Tregocel® supplementation, participants observed improved functional capacity confirmed in the distance in 6MWT and in the heel-thigh distance flexion test, decreased level of pain, and improved WOMAC scores for all domains.
Knee osteoarthritis (OA) accounts for approximately 85% of the burden of OA worldwide. Knee OA is a whole joint disorder involving structural alterations in the hyaline articular cartilage, subchondral bone, ligaments, capsule, synovium, and periarticular muscles. The complex knee OA pathogenesis includes mechanical, inflammatory, and metabolic factors, eventually leading to the synovial joint’s structural destruction and failure. This review aims to present an overview of current knowledge on dietary supplements, such as glucosamine, chondroitin, methylsulfonylmethane, diacerein, avocado-soybean unsaponifiables, curcuminoids, as well as boswellic acids. Results originating from several small studies with natural products in managing knee OA are encouraging. However, additional well-designed placebo-controlled clinical trials are required.
