Abstract Background and Aims Chronic kidney disease (CKD) is considered a global medical and public health issue. CKD takes a special place among non-infectious diseases because of its prevalence (6-20% according to different surveys and studies) and is associated with a poor life quality, complications and high risk of mortality. In recent years, there have been new biomarkers requiring more research in this area. One of these biomarkers is Fibroblast growth factor-23 (FGF-23) which is found as a bone derived hormone and might be a predictor of progression. However, the role of FGF-23 in CKD progression in children has not been adequately studied, especially on the early stages. Nowadays, the study of FGF-23 in children and the question of the clinical importance of this marker are relevant. Therefore, the aim of our study was to establish the role of FGF-23 in CKD progression in children. Method A prospective study was conducted on 73 children with different stages of CKD and 14 healthy individuals (control group) matched by age and gender. There were approximately equal numbers of patients in study groups. An average age was 9.61±1.05 years. Exclusion criteria: active inflammatory, bone, infectious, oncological, immunological diseases, taking steroids and vitamin D supplements. Laboratory measurements included all common clinical and biochemical indicators. Serum concentration of intact FGF-23 was assessed by using the ELISA method (Biomedica Medizinprodukte GmbH, Austria). Statistical analysis was conducted in MS Excel 2016 and SPSS 18.0. Results The normal range of FGF-23 for this kit was 0.1-1.5 pmol/l. The average value of FGF-23 in the control group was 0.69±0.12 pmol/l. Further studies in the groups with different stages of CKD revealed that FGF-23 concentration gradually rose in parallel with stages of CKD, and it reached the maximum on the last stage. It should be noticed that the level of FGF-23 concentration on the first stage of CKD was normal (0.73±0.14 pmol/l) and the comparison with healthy individuals revealed no significant differences. What is remarkable, despite the fact that the average value of the second stage patients was normal (1.36±0.2 pmol/l), there was a statistically significant difference with the control group (p=0.008). The levels of FGF-23 on the next stages were 2.52±0.52 pmol/l, 5.42±1.61 pmol/l, and 12.16±1.55 pmol/l, respectively. The differences were considerable and proved by statistical analysis (p<0.01). Conclusion Our study showed that there is an upward trend of FGF-23 as CKD progresses from early to advanced stages. The results on the second and third stages indicate that FGF-23 should be considered as one of early biomarkers of CKD progression in children. Thus, there is a need for more studies in this area.

Coronary artery disease (CAD) is a clinical manifestation resulting from a narrowing of epicardial coronary arteries that supply blood and oxygen to the heart. Coronary artery disease is mostcommonlydue to atherosclerotic occlusion of the coronary arteries.Fibroblast growth factor 23 (FGF23) is a circulating peptide hormone secreted by bone cells,regulating phosphate and vitamin D metabolism. Several recent observational studies reported an independent association of circulating FGF23 with several cardiovascular disease (CVD) risk factors including left ventricular hypertrophy and vascular dysfunction,CVD progression and incident clinical CVD eventsand mortality.Apolipoprotein A1 (ApoA1) is the primary protein associated with high-density lipoprotein (HDL) particles,and plays a central role in reverse cholesterol transport. HDL cholesterol (HDL-C) and ApoA1 concentrations are inverlassely related to the risk for coronary artery disease. To find the role of fibroblast growth factor-23 in coronary artery disease and its associationwith Apolipoprotein-A1.This ccross –sectionalstudyincluded 42 elective patients attending the cardiology unit and the results of those patients were compared with 40 healthy control group. Blood samples were obtained for measurements of (FGF-23,troponin I,Apo-A1,total creatine kinase activity,urea,creatinine and lipid profile).The obtained results showed that there was a significant difference in serum FGF-23 in coronary artery disease (367.52 ± 128.52 pg/ml) as compared with the control (165.41 ± 53.65 pg/ml) (p< 0.05). There was a significant differences in Apo-A1 in coronary artery disease (2.03±0.90 mg/ml) as compared with the control (1.49 ± 0.25 mg/ml) (P = 0.014).There was a significant difference in age between CAD (58.66±8.85) and control group (51.125 ± 11.71) (P<0.005).There was a significant difference in TG where control (99.50 ± 21.59) differ from CAD (142.05 ± 66.24) (P = 0.006).According to the results that were shown in the tables, we can be conclude that higher levels of FGF23 and Apo-A1 may be associated with complications and mortality of CAD beside its associating with atherosclerosis in the Iraqi patients.

ABSTRACT Toilet training is an effort to train children to be able to control and urinate (BAK) and defecate (BAB). Toilet training is one of the main tasks of children at toddler age. Toilet training is one of the main tasks of children in toddler age which is very important to be done to create independence in children in controlling BAK and BAB and children know the parts of the body and their functions. Data in 2012 shows that ± 60% of parents do not teach toilet training to children from an early age. The aim of the study was to find out the effectiveness of toilet training education on maternal behavior and toilet skills in toddler age training (18-36 months). The study was conducted in July-August 2018. This type of quantitative research used the design of the Quasy pretest and posttest experiment with non-equivalent control group design. Samples were 36 mothers and 36 children with purposive sampling technique. Data analysis used Paired t test, Wilcoxon test, Man-Whitney test an Independent t test. The results showed that toilet training education through lecture methods, modules and maze games was more effective than toilet training education through lecture and leaflet methods on children's knowledge and abilities. Conversely, for the role of mothers in supervision there is no significant difference in effectiveness. Health education is recommended in health promotion programs to increase maternal knowledge, the role of mothers and the ability of toilet training children independently. Keywords: Toilet training, Lecture method, Module, Maze game, Leaflet, Knowledge, Role of mother, Children's ability.

Objective: India is the second country after China having the highest population prevalence of diabetes. Several research studies investigating diabetes have been done, but not much work has been done on prediabetes. The purpose of this study was to investigate the effect of nutrition and lifestyle modification on prediabetic females. Methods: A total of 120 prediabetic females from Ludhiana city were divided into 2 matched groups: control group (n = 60) and experimental group (n = 60). Impact of nutrition intervention for dietary and lifestyle modification (for 3 months) was assessed on the anthropometric, dietary, biochemical parameters, and diabetes risk score of the experimental group and control group (no intervention). Results: All the selected 120 subjects completed the study (experimental group = 60; control group = 60). There was significant difference in the changes between the 2 groups throughout the study. The fasting blood glucose and glycated hemoglobin A1c levels of the experimental group subjects reduced significantly ( P ≤ .01). However, no change was observed among the control group subjects. The lipid profile of the experimental group showed a significant improvement ( P ≤ .01). Conclusion: Nutrition counselling of the prediabetics regarding dietary and lifestyle modification is recommended so as to improve their metabolic control, thus preventing them from being diabetics.

AbstractPatients afflicted with melanoma show lower vitamin D serum levels (VDSL) than the healthy population. This hypothesis agrees with its well-known antiproliferative features. An observational study was carried out to collect VDSL in patients suffering from melanoma. Our aim was to identify a potential connection between low VDSL and the risk to incur melanoma. Furthermore, we studied the association between VDSL at the diagnosis of melanoma and other germane prognostic factors. The population held in regard was composed of 154 patients with a diagnosis of melanoma between 2016 and 2019. These patients were retrospectively collected from our follow-up storage. We compared VDSL to clinical and pathological parameters (age, sex, tumour location, Breslow’s depth, Clark’s level, histological subtype, ulceration, et aliqua). Moreover, we recruited a control group with negative melanoma history. Mean and median of VDSL were significantly lower in the melanoma group. Instead, we found a negative association between melanoma and VDSL > 30 ng/L (OR 0.11; p < 0.0001). No correlation between VDSL and both Breslow’s depth and Clark’s level was discovered, but the VDSL comparison between thin (depth ≤ 1 mm) and thick tumours (depth > 1 mm) revealed a statistically significant difference (21.1 ± 8.2 ng/L vs 17.8 ± 8.1; p = 0.01). Moreover, VDSL were significantly lower in melanomas with mitotic rate ≥ 1/mm2 (22.1 ± 8.3 ng/L; p < 0007). Nevertheless, no connection was found between VDSL and both ulceration and positive sentinel nodes (p = 0.76; p = 0.74). Besides, our study revealed no association between VDSL and histological subtype (p = 0.161). Lower VDSL correlate with thick and high mitotic rate tumours. Future prospective studies would investigate if appropriate upkeep of suitable VDSL can decrease the risk of primary and recurrent melanoma diagnosis.

ABCA1 and ABCG1 genes encode the cholesterol transporter proteins that play a key role in cholesterol and phospholipids homeostasis. This study was aimed at evaluating and comparing ABCA1 and ABCG1 genes expression in metabolic syndrome patients and healthy individuals. This case-control study was performed on 36 patients with metabolic syndrome and the same number of healthy individuals in Hamadan (west of Iran) during 2013-2014. Total RNA was extracted from mononuclear cells and purified using RNeasy Mini Kit column. The expression of ABCA1 and ABCG1 genes was performed by qRT-PCR. Lipid profile and fasting blood glucose were measured using colorimetric procedures. ABCG1 expression in metabolic syndrome patients was significantly lower (about 75%) compared to that of control group, while for ABCA1 expression, there was no significant difference between the two studied groups. Comparison of other parameters such as HDL-C, FBS, BMI, waist circumference, and systolic and diastolic blood pressure between metabolic syndrome patients and healthy individuals showed significant differences (P<0.05). Decrease in ABCG1 expression in metabolic syndrome patients compared to healthy individuals suggests that hyperglycemia, related metabolites, and hyperlipidemia over the transporter capacity resulted in decreased expression of ABCG1. Absence of a significant change in ABCA1 gene expression between two groups can indicate a different regulation mechanism for ABCA1 expression.

<p>The present study was an attempt to investigate the effect two types of corrective feedback (i.e., recast and metalinguistic) in order to find out which one is more effective on EFL learners’ speaking improvement and also to see if gender could play a role in the relative impact of the two types of corrective feedback on learners’ speaking ability. To this end, 65 EFL learners of intermediate level in one of language institutes in Shiraz, Iran were selected and divided into three groups including two experimental groups and one control. The instruments used to collect the data included IELTS test as the pre and post tests and Oxford Placement Test (OPT) in order to obtain the homogeneity in participants’ English proficiency. The collected data were codified and entered into SPSS Software (Version 22) and were analysed using descriptive statistics, t-test, and Tukey test. The results indicated that although applying these two types of corrective feedback could have made improvement in EFL learners’ speaking ability, there was not observed any significant difference between impacts of recast and metalinguistic on EFL learners’ production. The test results also indicated that there was not any significant difference regarding gender within the three groups. This homogeneity further shows that in this study, the gender variable did not have any effect on the role of corrective feedback and it can be concluded that the observed difference between metalinguistic group, recast group, and control group is just the result of the provided corrective feedback type which has acted as the intervening variable and the moderator variable such as gender did not prove to have any effect in the outcome of this study. The findings can contribute to syllabus design and teaching methodology areas.</p>

Objectives: In this study, we aimed to evaluate whether fibromyalgia patients had a higher fall risk compared to healthy individuals and to identify its relationship, if there was an increase, with clinical features. Patients and methods: Between March 2018 and September 2018, a total of 50 consecutive female patients with fibromyalgia (median age: 35 years; interquantile range [IQR], 27 to 40 years) and 50 healthy female volunteers (median age: 30 years; IQR, 23 to 40 years) were included in the study. Pain was evaluated with the Visual Analog Scale (VAS), life quality with the Nottingham Health Profile (NHP), balance functions with the Berg Balance Test (BBT), and the risk of falls with a posturography device. Disease activity of fibromyalgia patients was evaluated with the Fibromyalgia Impact Questionnaire (FIQ). Results: The mean fall risk index of the fibromyalgia patients was 45%. The fall risk index was significantly higher (p=0.010) and the BBT scores were significantly lower in the patient group (p<0.001). There was a significant difference in terms of fall risk between the control group and drug-free fibromyalgia patients; however, no significant difference was found between the balance scores of the two groups. In the fibromyalgia group, a weak positive relationship was determined between the fall risk index and the social isolation subscale of the NHP. Conclusion: Our study results showed an increased risk of loss of balance and falls in fibromyalgia patients, compared to healthy individuals. This fall risk increase was also detected in fibromyalgia patients who did not use drugs. These findings suggest a possible relationship between social isolation and an increased risk of falls.

In the last decade many studies unraveled the bone marrow (BM) niche regulation and crosstalk with hematopoietic stem cells (HSC) in steady state conditions and malignancies, but HSC-niche interactions are still underexplored in hematological inherited disorders. We have recently provided the first demonstration of impaired HSC function caused by an altered BM niche in a non-malignant disease, beta-thalassemia (BT) (Aprile et al., Blood 2020). BT is a congenital hemoglobin disorder resulting in severe anemia, ineffective erythropoiesis and multi-organ secondary complications, such as bone defects. It is one of the most globally widespread monogenic diseases, which can be cured by transplantation of HSC from compatible healthy donors or autologous HSC from patients upon gene therapy. Cases of graft failure have been reported, but causes have not been deeply investigated and might include an impaired HSC function and a defective supporting activity of the BM niche, worsened by age and disease progression. We showed that the prolonged residence of HSC into an altered BM stromal niche in BT Hbbth3/+ (th3) mice negatively affects stem cell number, quiescence and self-renewal. Moreover, we demonstrated that correction of HSC-stromal niche crosstalk rescues BT HSC function by in vivo reactivation of parathyroid hormone (PTH) signaling. Consistently with the common finding of osteoporosis in BT patients, we found reduced bone deposition and low levels of PTH also in the murine model. We investigated the potential mechanisms underlying the decreased PTH and bone defect and we focused on the role of fibroblast growth factor-23 (FGF-23). FGF-23 is a systemic hormone mainly secreted by osteocytes, which acts as negative regulator of bone metabolism by inhibiting bone mineralization and PTH production by parathyroid glands. Since FGF-23 is positively modulated by the anemia-related factor erythropoietin (EPO), we hypothesized that the high EPO levels in BT, subsequent to ineffective erythropoiesis, might contribute to increase FGF-23. We measured high levels of circulating FGF-23 in th3 mice (wt vs. th3: 399.7±69.77 vs. 1975±209.3 pg/ml, p&lt;0.01) and also in BT patients (HD vs. THAL: 94.2±3.8 vs. 125.8±9.2 RU/ml, p&lt;0.05). To provide proof of concept data of the causative role of FGF-23 on BT bone and stromal niche defects, we inhibited FGF-23 signaling. FGF-23 inhibition by in vivo administration of FGF-23 blocking peptide rescued the bone defect in th3 mice, by increasing trabecular bone mineral density (th3 vs. th3+FGF23inh: 117.7±3.3 vs. 181.1±6.9 mg/cm3, p&lt;0.0001). Importantly, the treatment restored the frequency of HSC to levels comparable to wild-type controls by expanding the pool of quiescent cells (th3 vs. th3+FGF23inh: 0.03±0.002 vs. 0.07±0.0% on Linneg BM cells, p&lt;0.0001). Consistently, we found increased the expression of key molecules by bone cells, such as Jagged-1 and osteopontin, involved in the functional crosstalk between HSC and the stromal niche. Interestingly, FGF-23 inhibition had also a positive anti-apoptotic effect on the expanded BM erythroid compartment, promoting the maturation of erythroid precursors, as already shown in models of secondary anemias. Preliminary evidence in BT patients showed negative correlations between FGF-23 levels and markers of bone homeostasis (e.g. osteocalcin and vitamin D) and positive correlations with makers of ineffective erythropoiesis (e.g. reticulocytes), thus proposing FGF-23 as the molecule at the crossroads of erythropoiesis and bone metabolism in BT. In vivo studies and molecular analysis in th3 mice and patients' samples will better unravel the causative role of EPO on FGF-23 levels in BT and the negative impact of high FGF-23 on bone mineralization and BM stromal niche-HSC interactions. Our findings uncover an underexplored role of FGF-23 in bone and BM niche defects in BT, as a condition of severe anemia and chronic EPO stimulation. The inhibition of FGF-23 signaling might provide a novel strategy to ameliorate bone compartment and restore HSC-BM niche interactions in BT, with a potential translational relevance in improving HSC transplantation approaches.
