Abstract BackgroundRecent evidences suggested that deficiency of Vit-D is associated with risk of ischemic stroke and its severity. The mechanism behind its relationship have been linked to total oxidant level and some other modifiable risk factor like hypertension, diabetes, smoking and alcohol consumption and tobacco chewing. However, there are disappearances in evidences. The aim of this study is to find out the role of Vit-D and Total oxidants in ischemic stroke and in disease progression.MethodsIn this case control study total 205 individuals of case and control enrolled in this study the demographic data like age, gender, ethnicity, dietary habit, addiction (smoking, alcohol, tobacco chewing) previous history of disease (hypertension, diabetes, any cardiovascular disease) were collected from family members and other medical record. ResultsThe mean age of case and control group of 63.91 ± 12.66 and 62.52 ± 7.04 respectively. There was significant difference between insufficient Vit-D level in case and control group (p<0.05) however, there were significant difference of MDA in the groups classified on the basis of Vit-D level in case and control (p<0.05) moreover, there were inverse association observed between Vit-D and MDA level in both case and control. Vit-D and MDA shows significant association ischemic stroke however, MDA have association with stroke severity. ConclusionThe result shows higher prevalence of Vit-D deficiency in ischemic stroke patients which induce MDA level parallelly. At low level of Vit-D and high level of MDA associated with the severity of stroke. Moreover, Vit-D and MDA shows significant association with stroke occurrence. Furthermore, MDA significantly associated with stroke severity however Vit-D does not show any association with stroke severity

Background: In developed countries, stroke is the third most common cause of mortality, following cancer and coronary heart disease. The increase risk is often seen in individuals with diabetes and is associated with poorer clinical outcomes (including higher mortality). That’s why assessment of risk factors for stroke are important.Methods: This age and sex matched hospital based case control study assessed the risk factors of ischemic stroke in tertiary care hospital for a period of one year. Sample size was calculated for matched case control (1:1 ratio) by n-master software and came out to be 189 pairs. All patients under WHO case definition were enrolled as cases for study purpose, controls were selected from the same hospital with disease other than stroke. Analysis was conducted through calculation of odd ratio (OR) and confidence internal (CI) by using SPSS 22.0 program. Odds ratio (OR) of risk factor was calculated using bivariate analysis.Results: Results revealed that male: female ratio among the case and control was 2.1:1, mean age of case and control were 58.86±13.03 and 58.21±12.67. Out of 189 Case, 59 (31.2%) were suffering from diabetes, while only 39 (20.6%) controls were having diabetes mellitus. P value was 0.02, which is significant.Conclusions: In the present hospital based case control study, it was found that diabetes mellitus was a significant risk factor among the ischemic stroke patients.

Background: Undoubtedly, stroke is an important public health problem as well as an important precursor of mortality and morbidity. It also leads to loss of disability adjusted life years as it causes long term severe disability. The objective of this study was to study association of lipoprotein (a) in ischemic stroke patients with matched controls.Methods: This is a prospective case controlled study. The study group includes 100 stroke patients consecutive admitted in medicine/neurology departments of our hospital, and 50 patients as control group admitted for nonvascular diseases. The ethical committee clearance was obtained from the appropriate authority appointed by the institution. Detailed history taking and neurological examination were done in all patientsResults: This case-control study shows that ischemic stroke patients have higher levels of Lp (a) as compared to that of controls. Thus, people with high Lp (a) levels may have higher predilection for developing ischemic stroke. Lp (a) levels do not correspond to stroke severity stroke in our study. Thus, higher Lp (a) levels do not lead to more severe type of stroke. Lp (a) levels do not correlate with the outcome of stroke, hence Lp (a) level may not be a good indicator for assessing prognosis or predicting mortalityConclusions: This case-control study shows that ischemic stroke patients have higher levels of Lp (a) as compared to that of controls. Thus, people with high Lp (a) levels may have higher predilection for developing ischemic stroke factors for stroke like diabetes, smoking and hypertension do not predisposed to higher Lp (a).

ObjectiveThe purpose of the study was to examine whether the insertion (I) and/or deletion (D) polymorphism of ACE confers susceptibility to primary pterygium in Sardinian patients in a case–control study.Methods and resultsPolymorphism genotyping was performed by nested PCR using genomic DNA extracted from the whole peripheral blood of participants with (n=251) and without (n=260) pterygium. DD, ID and II genotype frequencies were: 48%, 39% and 13%, respectively, for patients with pterygium, and 15%, 40% and 44%, respectively, for the control group. A statistically significant difference was found between the pterygium and control groups for the ACE I/D polymorphism (p<0.001). Moreover, a statistically significant difference was found between the DD and II groups (p<0.01; OR=10.49; 95% CI 6.18 to 17.79), DD+ID versus II group (p<0.01; OR=5.23; 95% CI 3.37 to 8.13) and DD versus ID groups (p<0.01; OR=3.21; 95% CI 2.04 to 5.04).ConclusionsStatistical analysis showed that the DD genotype is associated with an increased risk of developing pterygium, and with a good chance that the D allele may play an important role in the development of disease.

Abstract Back groundThe precise etiology of infantile colic has not been elucidated after many years of research. In this study, we aimed to determine the association of fecal calprotectin with infantile colic.MethodThis case control study was performed on colicky infants referred to pediatrics clinics in Zanjan over a 6-month period. Infantile colic was clinically defined based on wessel criteria. The control group consisted of healthy infants matched for age, sex, weight, and type of feeding with the case group. Fecal calprotectin levels were measured in both groups by the ELISA method.ResultsForty infants were divided equally into case and control groups. The cases consisted of 11 boys (55%) and 9 girls (45%) with a mean age of 63 days and in the control group there was 12 boys (60%) and 8 girls (40%) with mean age of 48 days. Fecal calprotectin was positive in 17 (85%) cases and 6 (30%) controls. This difference was statistically significant. There was no significant difference in fecal calprotectin regarding sex, age, weight and type of nutrition in both colicky infants and controlsConclusionFecal calprotectin levels in colicky infants were significantly higher than healthy infants.

Abstract Background Parkinson’s disease is one of the neurodegenerative disorders that is caused by genetic and environmental factors or interaction between them. Solute carrier family 41 member 1 within the PARK16 locus has been reported to be associated with Parkinson’s disease. Cognitive impairment is one of the non-motor symptoms that is considered a challenge in Parkinson’s disease patients. This study aimed to investigate the association of rs11240569 polymorphism; a synonymous coding variant in SLC41A1 in Parkinson’s disease patients in addition to the assessment of cognitive impairment in those patients. Results In a case -control study, rs11240569 single nucleotide polymorphisms in SLC41A1, genes were genotyped in 48 Parkinson’s disease patients and 48 controls. Motor and non-motor performance in Parkinson's disease patients were assessed by using the Movement Disorder Society-Sponsored Revision of the Unified Parkinson’s Disease Rating Scale (MDS-UPDRS). The genotype and allele frequencies were compared between the two groups and revealed no significant differences between case and control groups for rs11240569 in SLC41A1 gene with P value .523 and .54, respectively. Cognition was evaluated and showed the mean ± standard deviation (SD) of WAIS score of PD patients 80.4 ± 9.13 and the range was from 61 to 105, in addition to MMSE that showed mean ± SD 21.96 ± 3.8. Conclusion Genetic testing of the present study showed that rs11240569 polymorphism of SLC41A1 gene has no significant differences in distributions of alleles and genotypes between cases and control group, in addition to cognitive impairment that is present in a large proportion of PD patients and in addition to the strong correlation between cognitive impairment and motor and non-motor symptoms progression.

Sperm Telomere Length

To study the relevance of sperm telomere length and infertility in men. : Our case-control study included twenty-five males in couple with sub-fertility/infertility (test group) and twenty five healthy males (control group) with proven paternity in the age group 25 to 35 years. The Absolute Sperm Telomere length (aSTL) was measured by real-time PCR. We investigated whether any significant difference in the aSTL value existed between the groups and analysed the relationship between aSTL and other sperm parameters.The mean (SE) aSTL recorded in the infertile cases was significantly shorter than for the control group being 140.60 (6.66) Kb/genome and 239.63 (12.32) Kb/genome respectively (p &#60;0.001) A weak correlation was eminent between aSTL kb/genome and the total sperm count mil/ml (rho= 0.04, p - 0.86), progressive sperm motility (rho= - 0.02, p=0.934) and sperm viability (rho= - 0.07 p=0.741) in the infertile group. The measurement of aSTL by real-time PCR is a simple and rapid method that offers further paramount information with respective to the quality of sperm. It is befitted for epidemiological studies, hence opening new perspectives in the evaluation of male infertility. Limitations - Our study was confined to men aged between 25 and 35 years. Further comparative studies are needed to explore the significance of STL and infertility in older males. Additional studies will help illumine the significance of aSTL as a prognostic biomarker in assisted reproduction.

Abstract Background Coronary hearth diseases are among the main causes of death in adults. Increase of oxidative stress and defects in antioxidant defense play a major role in endothelium performance and are an effective factor in progress of atherosclerosis. Some studies have also reported different malondialdehyde and total antioxidant capacity among the atherosclerosis patients.Methods In this case-control study, 44 atherosclerosis patients referring to Shahid Madani treatment-education center were considered as the case group; while 44 healthy peoples were placed in the control group. Demographic data and anthropometric indices were measured. Food frequency questionnaire and international physical activity questionnaires were also completed. After 12 hours of fasting, 10 ml blood was sampled from the participants. Uric acid, vitamin C, TAC and MDA were also measured. The data were finally analyzed by SPSS Ver 22 software.Results A significant difference was observed between the two groups in terms of uric acid (P<0.001) and vitamin C (P<0.03). However, mean MDA and TAC showed no significant difference between the two groups. The two groups’ difference in terms of vitamin A, E and beta carotene, zinc and selenium intake was not significant. A significant difference was however detected between the two groups in terms of vitamin C (P<0.047). A significant relationship was also observed between the systolic pressure and CHD (P<0.028).Conclusion Results of this study indicated that the uric acid and vitamin C levels of atherosclerosis patients had significant increase and decrease in comparison with the healthy subjects, respectively. Mean TAC and antioxidant levels of their diets (except for vitamin C) showed no significant difference. Systolic blood pressure of the patients was significantly higher than the controls.

Abstract Purpose: The aim of this study was to investigate occupational risk factors associated with bladder cancer. Materials and Methods: In this case–control study, control group included patients who referred to a specialized clinic in the same city and hospitals where patients had been registered. Data were entered into SPSS software. Odds ratios (OR) were calculated for occupational variables and other characteristics. Then, using logistic regression, the association between cancer and drugs was studied while smoking was controlled. Results: Cigarette smoking, even after quitting, was also associated with bladder cancer (OR = 2.549). Considering the classification of occupations, the OR of working in metal industry in patients was 10.629. Multivariate analysis showed that use of the drug by itself can be a risk factor for bladder cancer. Drug abuse together with the control of smoking increased the risk of bladder cancer by 4.959. Conclusion: According to the findings of this study, contact with metal industries such as welding, and working with tin was found as a risk factor for bladder cancer. In addition, cigarette smoking and opium abuse individually were associated with bladder cancer.

Abstract Background:phosphate homeostasis is mediated through complex counter regulatory feed-back balance between parathyroid hormone, FGF-23 and 1,25(OH)2D. Both parathyroid hormone and FGF-23 regulate proximal tubular phosphate excretion through signaling on sodium- phosphate cotransporters II a and II c . However, the interaction between these hormones on phosphate excretion is not clearly understood. We performed the present study to evaluate whether the existence of sufficient parathyroid hormone is necessary for full phosphaturic function of FGF-23 or not. Methods:In this case-control study, 19 patients with hypoparathyroidism and their age- and gender-matched normal population were enrolled. Serum calcium, phosphate, alkaline phosphatase,parathyroid hormone, FGF-23, 25(OH)D, 1,25(OH)2D and Fractional excretion of phosphorous were assessed and compared between the two groups, using SPSS software. Results:The mean serum calcium and parathyroid hormone level was significantly lower in hypoparathyroid patients in comparison with the control group(P<0.001 and P<0.001, respectively). We found high serum level of phosphate and FGF-23 in hypoparathyroid patients compared to the control group (P<0.001 and P<0.001,respectively). However, there was no significant difference in Fractional excretion of phosphorous or 1,25OH2D level between the two groups. There was a positive correlation between serum FGF-23 and Fractional excretion of phosphorous just in the normal individuals (P <0.001, r = 0.79). Conclusions:Although the FGF-23 is a main regulator of urinary phosphate excretion but the existence of sufficient parathyroid hormone is necessary for the full phosphaturic effect of FGF-23.
