Purpose: To determine the levels of Vitamin D in children with myopia and to compare them with age matched controls. Study Design:  Case control study. Place and Duration of Study:  The study was conducted in Naseer Memorial Hospital, Dadhyal Azad Kashmir from March 2016 to March 2017. Material and Methods:  Two hundred patients were selected using convenient sampling technique and were divided two groups (group I Myopic and group II control). Myopia was labeled if after subjective refraction a Spherical Equivalent (SE) of −0.50 diopters (D) or more was found. Vitamin D levels were measured by radioimmunoassay technique with Diasorin SR® kit following the user’s manual. Vitamin D levels less than 20 ng/ml were considered Vitamin D deficient following the standards of American academy of pediatrics. The collected data was entered in the statistical package for social sciences (SPSS) version 21 for analysis. Independent t–test was used to determine the significant difference of means between controls and patients. P-values less than 0.05 were considered significant. Results:  Mean age of controls and myopes were 10.65 ± 3.9 and 10.20 ± 2.5 years respectively. Vitamin D levels in myopic children were found to be 14.95 ± 3.75 ng/ml and there was no significant difference in mean values of Vitamin D levels in myopic and control group. Conclusion:  We found no difference in Vitamin D levels of myopic and non myopic children and concluded that Vitamin D has no role in development or progression of myopia.

AbstractThe aim of this study was to evaluate the effect of prescribing vitamin D on improving the symptoms of patients diagnosed with urosepsis. The participants were randomly divided into two equal groups (each consisting of 50 patients). The patients in the first group received standard treatment with 300 000 units of injected vitamin with a volume of 1 cc. As for the patients in the second group, they received standard treatment along with 1 cc normal saline injected to them as placebo. Vital signs of the patients were checked every 6 h, while their CBC, EXR, CRP, creatinine, urea, and uric acid were checked 0, 24, 48, and 72 h following the interventions. Calcium, phosphorus, and vitamin D levels were measured 72 h following injection of the medicine. A significant difference was observed between the two groups in terms of the number of WBC’s in 24th, 48th, and 72nd hours. A similarly significant difference was reported between the case and control group in terms of the average BUN within 24th, 48th, and 72nd hours. The difference observed between the two groups in terms of average Cr within the 0th, 24th, 48th, and 72nd hours and in terms of days of hospitalization was also significant. Considering these results and keeping in mind the fact that no particular side effects were reported as a result of utilizing muscular injections of vitamin D and the easy and cheap use of this medicine, it can be used in auxiliary treatment of patients with urosepsis.

Abstract BackgroundAtopic dermatitis (AD) is a chronic, inflammatory, and severely Pruritus cutaneous disease that has an immunologic base. The most common treatments are topical steroids, which bring many adverse side effects. Vitamin D can adjust the immune system; therefore, in this study, we investigated the effect of vitamin D on the abundance of Treg cells in AD patients. MethodsIn this interventional study, 40 subjects who completed the intervention were enrolled, including 20 AD patients (as the experimental group) and 20 healthy subjects (as the control group). Accordingly, the subjects whose vitamin D levels was less than 30 ng/ml were assigned to receive vitamin D (1000 IU) daily for a 2-month duration. The severity of AD was evaluated based on SCORAD (Scoring Atopic Dermatitis) and the amount of CD4+CD25+Foxp3+Treg cells was also assessed using Flow cytometry. ResultsAverage serum level of vitamin D before performing the treatment in the experimental (14/90±4/5) and control groups (15/95±5/0) was lower than that of after the treatment (experimental group 24/60±5/2 and control group 23/60±7/3) (P<0.001). As well, there was a significant difference between the average scores of SCORAD after the vitamin D intervention (P<0.001). The amount of Treg cells significantly increased in the experimental group (P=0.002, Diff=0.35) after performing the intervention.Conclusionit was found that besides conventional medicines, Vitamin D can be adjusted as an effective complementary therapy by modulating the immune system.Trial registration: IRCT20150716023235N13, Registered 11 Feb 2018, https://www.irct.ir

Objective: To investigate whether serum vitamin D levels have an effect on pseudoexfoliation (PEX) glaucoma/syndrome development and on the control of glaucoma in these cases. </P><P> Method: A total of 31 cases with PEX glaucoma, 34 cases with the PEX syndrome and 43 control subjects of similar age and sex were included in the study. Vitamin D levels were compared between the groups and also between the cases where glaucoma surgery was performed or not. Results: PEX glaucoma group consisted of 17 males and 14 females, PEX syndrome group of 27 males and 7 females, and the control group of 27 males and 16 females. The mean age was 70.9±8.9 years, 72.1±7.3 years, and 67.9±9.1 years in PEX glaucoma, syndrome and control group, respectively. Mean vitamin D levels were 9.4±7.7 ng/mL, 7.9±6,1 ng/mL, 11.5±14.2 ng/mL in PEX glaucoma, syndrome and control group, respectively (p>0.05). The mean serum vitamin D level was 8.04±4.7 ng/mL in those who underwent glaucoma surgery and 10.1±8.7 ng/mL in those who didn't undergo glaucoma surgery in PEX glaucoma group (p>0.05). No difference was found between the PEX glaucoma subgroups in terms of the mean deviation when classified according to vitamin D levels (<10 ng/mL, ≥10 ng/mL) (p>0.05). Conclusion: Although we found no statistically significant difference between the PEX syndrome/ glaucoma, and control group in terms of serum vitamin D levels, serum vitamin D levels were lower in PEX syndrome and glaucoma group than control group. Our results indicate that serum vitamin D levels have no effect on the development of PEX glaucoma/syndrome or the control of the disorder in cases with PEX glaucoma. However, these results need to be supported with further studies on a larger number of patients and with longer follow-up.

BACKGROUND: Serum otolin-1 is an inner ear protein exclusively expressed in otoconia and cells of vestibule and cochlea. Serum otolin-1 is found to be quantifiable in patients with BPPV. Low Vitamin-D is associated with pathogenesis of BPPV. Since otoconia degeneration contributes to BPPV, lack of Vitamin-D may impact otoconia structure and integrity. OBJECTIVE: We aimed at studying the s.otolin-1 as biomarker and significance of vit-D in BPPV. MATERIAL AND METHOD: 23 patients in test and control groups respectively were chosen within the age of 20 to 65 years. All the patients were diagnosed using Dix Hallpike menouver and head roll test, patients were treated with appropriate Canal Reposition Menouver (CRM). RESULTS: Serum Otolin-1 levels among the test ranged from 366 to 882 pg/mL with mean of 585.17 pg/mL whereas in control group ranged from 223 to 462 pg/mL with mean of 335.26 pg/mL. Mean Vitamin-D levels among the test group was 22.67 ng/mL (Range = 6.3–68.4) and that of control 15.43 pg/mL (Range = 5.4–27.7) respectively. The relationship between the serum Otolin-1 and Vitamin-D was not statistically significant. CONCLUSION: Otolin-1 levels is increased in BPPV patients and is sensitive in BPPV, specificity needs to be validated. Role of vitamin-D with respect to inner ear proteins needs further investigation.

It is suggested that a number of environmental and genetic factors trigger the formation of progressive kidney damage and complications. One of these factors is inflammation, it occurs as a result of a series of mechanisms included within a number of cytokines. Vitamin-D, IL-6, PCT and hs-CRP are also valuable biomarkers in terms of mortality in dialysis patients in this sense. Vitamin D deficiency is common in patients with chronic kidney disease (CKD) and is associated with inflammation. In recent years, some randomized controlled trials have revealed the effect of Vitamin D on inflammation in CKD patients, but the results are conflicting. The aim of this study is to investigate the relationship between Vitamin D, high-sensitivity C Reactive Protein (hs-CRP), procalcitonin and IL-6, and to evaluate the relation of Vitamin D levels with inflammation in PD patients, HD patients and controls. This study was carried on with 40 patients receiving on hemodialysis treatment, 40 patients receiving peritoneal treatment with renal failure disease and with a control group consisting of 40 healthy individuals. Vitamin D levels were measured by HPLC, PCT and IL-6 levels were measured by chemiluminescent method, hs-CRP is measured by nephelometric method. For Vitamin D, there was no differences between the groups. For PCT, there was a significant difference between all groups. For IL-6, while there was no difference between peritoneal and hemodialysis groups, a significant difference was determined between the peritoneal dialysis and control groups. For hs-CRP, there was a significant difference among all groups. While correlation was found between serum PCT levels with IL-6 and hs-CRP, no correlations were found between serum PCT with Vitamin D levels. Although a correlation was found between serum IL-6 levels and hs-CRP, no correlation was detected between serum IL-6 and Vitamin D levels. No correlations were detected between Vitamin D andPCT, IL-6 and hs-CRP.

The purpose of our study is to determine the correlation between the effects of smoking, triglycerides and cholesterol (total, HDL, LDL) and periodontal disease. 90 patients, smokers diagnosed with periodontal disease and 30 nonsmoker patients (control group), in the age of 30-60 years, were studied. Patients were divided into 4 groups, each of 30 patients as follows: group I - smokers up to 10 cigarettes a day, group II-smokers between 10-20 cigarettes a day, group III-over 20 cigarettes a day, group IV- control group, nonsmokers. The values of the Silness-Loe dental plaque index (DPI), the gingival bleeding index (GI), the Periodontal Disease Index (PDI) -Ramfjord were noted in both the examined and control groups. The values of total cholesterol and HDL cholesterol showed statistically significant difference between the mean values �in the examined groups, while mean values �of HDL cholesterol in the second and third examined subgroups and control group were in higher range than the normal one. We concluded also that there is a relationship between smoking, the number of cigarettes smoked and the periodontal disease.

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.

<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>
