Objective Search for the relationship between innate immunity and bone and cartilage metabolism in patients with developmental dislocation of the hip (DDH). Material and methods The study included 27 patients with DDH who underwent reduction of the hip at pediatric orthopaedic department of the Federal State Budgetary Educational Institution of Higher Education «Privolzhsky Research Medical University» of the Ministry of Health of the Russian Federation. The patients aged 15.0 ± 1.7 months. The study enrolled the babies diagnosed with grades III, IV, V unilateral or bilateral DDH as classified by M.V. Volkov, 1978. Patients with hip dysplasia (grade I DDH) or congenital hip subluxation (grade II DDH) were excluded from the study. The control group consisted of 15 patients without musculoskeletal pathology. The mean patients' age was 24.0 ± 1.8 months. Peripheral blood monocytes, toll-like receptor (TLR2, TLR4, TLR5) expression, serum concentrations of fibroblast growth factors (FGF), vascular endothelial growth factor (VEGF), serum magnesium, type I, II collagen and aggrecan were measured in patients of major and control groups. Results DDH patients showed statistically significant differences in all the parameters measured except for the type 2 collagen with decrease in peripheral blood monocyte and increase in TLR2 and TLR5 expression, slight increase in the serum magnesium with decreased concentration of aggrecan and increased FGF level. There was a two-fold decrease in VEGF level and a two-fold increase in type I collagen concentration. There were moderate significant correlations for monocyte matches TLR2 and TLR2 – TLR5 in major group. Three main factors detected with factor analysis included (1) monocytes, TLR2 and TLR5 as most meaningful, (2) FGF and type 2 collagen and (3) aggrecan. Conclusion The findings suggested that specific factors of innate immunity can be involved in the pathogenesis of DDH. Toll receptors regulate many metabolic pathways and connective tissue metabolism, More studies are needed to further explore this topic.

Pathogenesis of ischemic stroke  is actively  involved  in the  system  of innate immunity. Under conditions of cerebral  ischemia, a number of biologically  active  substances are  released  that  interact with innate immunity receptors, in particular TLR2  and  TLR4, which  exacerbate inflammation in brain  tissue. Identification of predictor markers  at the level of the innate immunity system may foresee the clinical course of ischemic stroke and ensure timely treatment. Our objective was to study expression of TLR2 and TLR4 receptors in peripheral blood leukocytes  in patients with ischemic stroke in the dynamics of the disease. 27 people  were included in the study. The main  group consisted of patients with ischemic stroke of varying severity (n = 19). Patients of the main  group were divided into two subgroups:  with an NIHSS index value of < 10 (n = 10) and > 10 (n = 9). The control group included healthy  donors  with no history  of acute  and chronic inflammatory diseases (n = 8). Peripheral blood  leukocytes  were used as the  test material. To determine expression  of the TLR2  and TLR4  genes, RT-PCR in real time was used. Surface  expression  of TLRs was determined by flow cytometry. A study of the TLR2 and TLR4 gene expression showed that on the 1st, 3rd  and 7th  day post-stroke, the TLR4 gene expression  in patients was significantly  increased, when compared to the control group (p < 0.01), whereas TLR2 gene expression on the 3rd  day of the disease was not statistically different from the control group. A study of surface expression  of receptors showed that the average TLR2 fluorescence intensity on the patients’ peripheral blood monocytes was significantly  increased on the 1st  and 3rd  day of disease when compared to the control group.  The  surface  expression  of TLR4  on monocytes has a statistically significant  increase  only on day 7. Assessment  of surface expression  of TLRs in subgroups  with different  severity values by NIHSS showed that  patients with a NIHSS index > 10 had a significantly  higher  level of surface of TLR2  expression  over the observation period, while the largest difference in TLR4  expression  in the subgroups  was observed  on the 1st day of the disease (p < 0.05). Patients with ischemic stroke showed an increase  in TLR2 and TLR4 expression at the gene and protein level, compared to healthy  donors. These indices can be considered possible predictors for clinical  prognosis  of ischemic stroke.

Aim. To study molecular biomarkers in patients with type 2 diabetes (T2D) in combination with heart failure with preserved (HFpEF) and mid-range ejection fraction (HFmrEF) and compare the data obtained with clinical characteristics of myocardial remodeling.Material and methods. The study included 42 patients with T2D (men — 53%, mean age — 60 years) with clinical manifestations of class II HF: 29 patients with HFpEF (group 1) and 13 patients with HFmrEF (group 2). The control group consisted of 13 healthy people, which were comparable in sex and age and had a normal body mass index (BMI). Patients received stable glucose-lowering and optimal drug therapy for HF for 3 months prior to enrollment in the study. Patients with HFpEF and HFmrEF were comparable in clinical and demographic parameters, had glycated hemoglobin (HbA ) of 8,5% and 8,8%, respectively (p>0,05), increased BMI or grade I-II obesity.We studied following biomarkers: NT-proBNP, highly sensitive C-reactive protein (hsCRP), sST2, galectin-3, procollagen type I C-terminal propeptide (PICP), matrix metalloproteinase 9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1).Results. Volumetric parameters of the left ventricle (LV),LV mass indexed to growth and NT-proBNP were higher in the group of HFpEF patients (p<0,05 for all). The concentrations of galectin-3, PICP were higher, and the MMP-9/TIMP-1 ratio decreased in patients with T2D compared with the control group (p<0,05 for all). PICP values were higher in patients with HFmrEF compared with patients with HFpEF (106,4 (85,4; 140,4) ng/ml vs 46,8 (12,6; 98,6 ng/ml), respectively, p=0,043). In patients with T2D and HF, a relationship was found between TIMP-1 andLV end-diastolic volume (r=-0,68; p=0,042).Conclusion. Patients with HFmrEF and T2D have higherLV volume and mass, higher concentrations of NT-proBNP and PICP in comparison with patients with HFpEF. The direction of MMP-9/TIMP-1 changes may reflect a decrease in antifibrotic processes. Further prospective studies on large samples using a multiple biomarker model are required in T2D and various HF phenotypes.

Abstract Aquatic treadmills improve range of motion and increase muscular strength in mature horses; however, effects of buoyancy on inflammation and cartilage metabolism in young horses are not well investigated. Therefore, thirty Quarter Horse yearlings of similar breeding were stratified by age, BW, and sex and randomly assigned to one of three treatment groups during a 140-d trial to evaluate the influence of aquatic vs. dry exercise on joint inflammation and cartilage metabolism in young horses transitioning to an advanced workload. Treatment groups included non-exercise control (CON; n = 10), dry treadmill exercise (DRY; n = 10), or aquatic treadmill exercise (H2O; n = 10; water at 60% wither height). Animals were housed in individual stalls and allowed turnout for a minimum of 10 h/d. During Phase I, DRY and H2O walked on treadmills 30 min/d, 5 d/wk from d 0 to d 112. Phase II represented transition to an advanced workload 5d/wk for 28 d (Table 1). Every 28 d following exercise, synovial fluid samples were collected and analyzed for prostaglandin E2 (PGE2), collagenase cleavage neopeptide (C2C), collagenase of type I and type II collagen (C1,2C), and carboxypeptide of type II collagen (CPII) using commercial ELISA kits. All data were analyzed using PROC MIXED of SAS, including random effect of horse within treatment, and repeated effect of day. Baseline treatment differences were accounted for using a covariate structure. There were no treatment ′ day interactions of synovial inflammation or markers of cartilage metabolism; however, there was an effect of day for each selected marker (P &lt; 0.03). Changes in biomarkers of cartilage turnover in horses exercised at the walk, whether dry or aquatic, could not be distinguished from horses with access to turnout alone. This indicates that there are no negative effects of buoyancy on cartilage metabolism in yearlings transitioned from aquatic exercise to 28-d advanced workload.

The paper analyzes the current literature data and the results of our own researches concerning the state of the cytokine network: pro- and anti-inflammatory cytokines (interleukin (IL) 1α, IL-1β, IL-4, IL-6, IL-10, IL-17 and tumor necrosis factor (TNF) α), α- and β-chemokines, including IL-8 and IL-16, as well as adipokines (leptin and adiponectin) in the peripheral blood of patients with type 2 diabetes (T2D) with normal and increased body weight/obesity. It has been shown that patients with T2D are cha­racterized by an increased content of proinflammatory cytokines (IL-1, IL-6, IL-17, TNFα), α- and β-chemokines in the peripheral blood, including IL-8 and IL-16, as well as leptin with a decrease in adiponectin content. In lean patients (with body mass index (BMI) < 25.5 kg/m2) compared to lean normoglycemic individuals from the control group (BMI < 25.5 kg/m2), there is a small but significant increase in IL-1β, IL-6, IL-17, TNFα and leptin, which, as BMI increases, significantly increases in severe obesity (BMI > 30.0 kg/m2), especially in obese women (BMI > 35.0 kg/m2). Similarly, an increase in proinflammatory cytokines is observed in normoglycemic people, but not as signifi­cant as in T2D. Less clear data were obtained when during determination of the anti-inflammatory cytokines IL-4 and IL-10, which is explained by a significant polymorphism of their genes, and both protective and compensatory effects on pro-inflammatory cytokine rise. In T2D patients, especially those with obesity, there is an increase in the leptin level and a decrease in the adiponectin content. The severity of the course and the percentage of mortality are closely associated with the BMI of patients. The effectiveness of the fight against an increase in the incidence of T2D should be primarily aimed at preventing obesity, and in case of already developed T2D — at reducing concomitant obesity. The analysis of the data presented also suggests that a sharp increase in the content of pro-inflammatory cytokines (so called cytokine storm) observed in patients with T2D and obesity infected with COVID-19, is a consequence of the summation and potentiation of already existing inflammatory process.

Pathological change experienced by patients with type 2 diabetes mellitus is impaired peripheralblood circulation, especially in the lower limbs and feet. Peripheral blood circulation can be examinedby measuring Ankle Brachial Index (ABI). Therapeutic exercise walking is one of physical activitieswhich can improve blood circulation. This research goal was to analyze the effect of therapeuticexercise walking on peripheral blood circulation in patients with type 2 diabetes mellitus. Theresearch design was randomized control group pretest-posttest design. The sample size was 15respondents as control group and 15 respondents as treatment group. Data was analyzed by usingdependent t-test and independent t-test with significant level of 0.05. This result showed a significantincrease of ABI after therapeutic exercise walking in the treatment group (p= 0.001). However therewas a significant decrease of ABI between pretest and posttest in control group (p=0.010).Independent t-test indicated a significant difference of ABI between treatment group and controlgroup (p=0.000). So, it can be concluded that there is an influence of therapeutic exercise walking onthe peripheral blood circulation in patients with type 2 diabetes mellitus. Nurses should applytherapeutic exercise walking to improve peripheral blood circulation in patients with type 2 diabetesmellitus.Keywords: type 2 diabetes mellitus, therapeutic exercise walking, ankle brachial index

Background: Among different complications of diabetes, ddiabetic retinopathy is one of the leading causes of blindness in the world. Increase in the frequency of lower serum magnesium levels have been reported among patients with diabetes. Materials and methods: A total of 120 subjects were included in this study and divided into 3 groups. The study groups consisted of 40 patients that are type 2 diabetes with retinopathy and 40 patients with type 2 diabetes without retinopathy and control group consisted of 40 healthy subjects respectively. Both cases and controls were subjected to estimation of biochemical parameters. Results: Among the study population, (80) 66.67% participants were cases and another (40) 33.33% participants were controls. Among the people who had mild NPDR, the median Mg was 1.90 (IQR 1.80, 2.00). It was 1.90 (1.70, 2.00), 1.75 (1.67, 1.92), 1.8 (1.69, 2.0) and 2.10 (1.90, 2.20) among people with DM retinopathy moderate NPDR, severe NPDR, Proliferative retinopathy and no retinopathy respectively. The difference in the Mg across DM retinopathy was statistically significant (P Value 0.008). The difference between the values among both the case and control groups for certain parameters such as SBP, FBG, PPBG, HbA1c, Magnesium, Urea, and Creatinine were found to be statistically significant. Conclusion: Serum magnesium levels were significantly lower in patients with diabetic retinopathy compared to diabetics without complications and control group.

This study aimed to explore the risk factors attributed to osteoporosis in newly type 2 diabetes mellitus (T2DM) patients. This study aimed to recruit 244 T2DM patients and 218 non-diabetic controls. We collected demographic characteristics, medical history, bone mineral density and biomarkers including bone specific alkaline phosphatase (BALP), osteocalcin, N-terminal peptide of type I procollagen (P1NP), tartrate-resistant acid phosphatase 5b (TRCAP-5b), β-Cross Laps of type I collagen-containing cross-linked C-telopeptide (β-CTX), 25-hydroxyvitamin D, parathyroid hormone were recorded or detected. Bone mineral density (BMD) was our primary outcome. Based on the result of BMD, we divided both the control group and T2DM group into three subgroups: normal bone mass, osteopenia and osteoporosis. In control group, we found age, sex, menopausal status, BMI, P1NP, BALP, TRACP-5b, osteocalcin, and corrected serum calcium are differential among three subgroups. In T2DM group, we found age, sex, menopausal status, drinking status, BMI, HbA1c, TRACP-5b and OC were differential among three subgroups. In T2DM and control groups, age, female, postmenopausal status, BALP, TRACP-5b and osteocalcin were positively correlated while BMI was negatively correlated with osteoporosis. In control group, β-CTX was positively correlated with osteoporosis. In T2DM group, HbA1c and corrected serum calcium concentration were positively correlated with osteoporosis. After further adjustment of age, BMI in male, TRACP-5b was positively correlated with the risk of osteoporosis in newly diagnosed T2DM. After adjusted of age, BMI and menopausal status in female, OC was positively correlated with the risk of osteoporosis in newly diagnosed T2DM and controls. In female T2DM, BALP and P1NP were positively correlated with the risk of osteoporosis. In conclusion, age, BMI and menopausal status are common risk factors for osteoporosis in diabetic and non-diabetic patients, however TRACP-5b, BALP and osteocalcin are special risk factors for osteoporosis in newly diagnosed T2DM patients but not non-diabetic patients, which may be applied to identify osteoporosis risk in T2DM patients, but this result needs to be proven with fracture data.

Hyperglycemia alone may not explain the increased risk of cardiovascular diseases (CVDs) in patients with type 1 diabetes (T1D) compared with type 2. This study emphases on the evaluation of some platelet activity markers in patients with T1D, with relevance to some metabolic disorders as hyperlipidemia and hyperglycemia. This study was performed on 35 patients with T1D and 20 healthy controls. All participants were subjected to full history taking, clinical examination and assay of glycated hemoglobin (HbA1c), and lipid profile. The expression of CD62P and CD36 on platelets and the frequency of platelet–monocyte, and platelet–neutrophil aggregates were assessed by flow cytometry. Patients showed significantly higher expression of CD62P and CD36 than the control group. Platelets aggregates with monocytes were also higher among patients than the control group. Levels of CD36+ platelets, CD62P+ platelets, and platelet–monocyte aggregates revealed significant correlations with the levels of HbA1c, total cholesterol, low-density lipoprotein, and triglycerides. Hyperlipidemia and hyperglycemia accompanying T1D have a stimulatory effect on platelet activation which probably makes those patients vulnerable to CVD than nondiabetics.

Akt/mTOR/p70S6K1 signaling pathway plays an important role in the pathogenesis of cancer and diabetes. Macrophages and lymphocytes are involved in the pathogenesis of diabetes, diabetic atherosclerosis, formation of insulin resistance as well as immune response to cancer and tumor maintenance. The aim of the study was to determine the Akt activation by mTORC2 in peripheral blood mononuclear cell (PBMC) of patients with type 2 diabetes and cancer.The following groups were studied: control group, patients with type 2 diabetes, cancer patients and patients with both cancer and diabetes. The amounts of phospho-Akt (р-S473) and phospho-p70S6K1 (p-T389) were determined using ELISA kits.The amount of phosphorylated Akt significantly increases in PBMC of patients with cancer. There was no effect in PBMC from patients with type 2 diabetes and significant decrease in the amount of phospho-Akt in PBMC of the patients group both with cancer and diabetes. p70S6K1 activation was observed in PBMC of the groups 2 and 3 patients.Thus, chronic diseases such as type 2 diabetes and cancer can affect the signaling mechanisms in blood cells. The state of Akt phosphorylation in leukocytes can indicate the activity of mTORC1 and its substrates, which may be important for the evaluation of the pathological process and the efficacy of the drugs.

Background: Magnesium deficiency is a common problem in diabetic patients. Magnesium deficiency may increase the incidence of Type 2 Diabetic (T2D) and occurrence complications. Objective of this study aimed at determining the differences in serum magnesium levels and lipid profile among patients newly diagnosed with T2D and normoglycemic individuals.Methods: The cross sectional observation study design was conducted at Sri Aurobindo Medical College, from March 2018 to April 2019. Source populations were all patients who attending to the OPD, Department of General Medicine. A total of 75 patients were enrolled in this study. This study was divided in two group’s cases group (T2D) and second control group (Non-diabetic). First group not initiated on any oral-hypoglycaemic, anti-hypertensive or lipid lowering drugs, and healthy patients were included in control group.Results: Triglycerides (TG), Total Cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C) showed significantly (p<0.001) higher mean levels in T2D compared to the controls. The Magnesium and High-Density Lipoproteins-cholesterol (HDL-C) levels were significantly (p<0.001) lower among the T2D group compared to the control group. There was a significant inverse correlation (r2= 0.567, p<0.001) between Hemoglobin A1C (HbA1c) levels and serum magnesium.Conclusions: Serum magnesium levels and lipid profile were significantly different in T2D patients compared to control group.
