Abstract Purpose The role of oxidative stress in the pathogenesis of pterygium is still unclear. However, abnormal thiol disulfide homeostasis levels are involved in the pathogenesis of various systemic or ocular diseases. We aim to analyze dynamic thiol disulphide homeostasis in patients suffering from conjunctival pterygium using a contemporary technique. Methods Thirty-eight subjects suffering from pterygium and 35 age-gender matched healthy volunteers were recruited for study. For each case, total thiol, disulfide and native thiol levels in blood were obtained. Additionally, ratio of disulfide over total thiol, native thiol over total thiol and disulfide over native thiol were computed. Results The level of median native thiol was lower in pterygium group (318.2 µmol /L vs 333.4 µmol /L) and median disulfide was slightly higher in pterygium group (24.3 µmol /L vs 22.8 µmol /L) compared to control group. Both disulfide over total thiol and disulfide over native thiol ratios were higher in pterygium group, ratio of native thiol over total thiol was found to be higher in control group. Nevertheless, none of those differences were statistically significant at 95% confidence level. Notably, correlation test pointed to a negative correlation both between pterygium grade and native thiol and between total thiol and pterygium grade in pterygium group (P = 0.03 and 0.02 respectively). Conclusion A negative correlation hinting that slightly weakened dynamic thiol disulphide homeostasis in subjects with pterygium, a local ocular disease. Further studies with larger sample sizes may shed light on this potential relationship and justify systemic antioxidant therapies in these cases.

Obesity, an important public health issue, is a risk factor for many diseases and has been associated with many genes. The aim of this study was to investigate if there is an association between an NPY gene polymorphism, Leu7Pro, and obesity and/or obesity-related phenotypes. A total of 84 obese cases (45 female and 39 male) and a total of 77 non-obese control subjects (38 female and 39 male) were included in this case-control study. Body weight and height measurements were used for calculation of Body Mass Index (BMI) and the ones in the ranges of 18 to 25 kg/m2 were considered normal and the ones 30 kg/m2 and over were considered obese from the subjects. Minor allele frequency for Leu7Pro polymorphism was 3.5% and it was found to be associated to increased obesity in the population studied. No significant differences were observed between genotype distrubutions and allele frequencies for both obese and non-obese subjects. However, mean BMI values were found to be higher (38,88 ? 2,96) in obese cases having Pro7 allele than non carriers of this allele (35,37 ? 5,16), (p=0.044). This is the first study in a Turkey population which supports the role of Leu7Pro polymorphism in obesity. Further studies with larger sample sizes may confirm these findings and can contribute and shed light on the genetic factors playing a part in Turkey population.

BACKGROUND: The COVID-19 pandemic has created a wide range of sociocultural pressures on nurses. Resilience is defined as one’s ability to adapt to an unpredictable situation and it can be a factor in accepting an undesirable psychosocial situation. OBJECTIVE: The aim of the present study was to examine resilience in nurses in the face of job stress during the COVID-19 pandemic. METHODS: The study was carried out as a case-control study with participation of 400 nurses as the target group (nurses exposed to COVID-19 patients) and the control group (nurses not exposed to COVID-19 patients). To examine resilience and job stress, Conor and Davidson’s questionnaire and OSIPOW questionnaire were used respectively. RESULTS: The mean scores of job stress and resilience were significantly different between the target and control groups (p <  0.05). So that resilience in the target group was less than that in the control group. In addition, job stress in the target group was higher than that of the control group (p <  0.05). There was a significant and negative correlation between resilience and job stress and the correlation was stronger in the target group (p <  0.05). CONCLUSIONS: Given the high job stress score in the participants and its negative correlation with resilience, there is need to provide the health personnel with efficient preventive and treatment approaches, improve and educate the principles of resilience, improve mental health services system, and introduce programs to control some of demographical factors in job stress such as physical activity, and employment status of nurses.

Background: Toxoplasmosis is a common parasitic disease, which leads to serious disease symptoms in immunocompromised hosts and infants. Recent epidemiologic surveys showed that microbial agents may be associated with some cases of multiple sclerosis (MS). Objectives: This case-control study aimed to examine the role of Toxoplasma gondii in MS by evaluating sero-frequency of anti-T. gondii IgG (ATXAb) antibody between patients with MS and ordinary people in Shiraz Province, south of Iran during 2016 - 2018. Methods: Serum samples obtained from MS patients (n = 130), and a group of age and gender-matched controls (n = 130) with the same socioeconomic status with the patients’ group were collected to evaluate the prevalence of T. gondii IgG antibodies (ATXAb). Moreover, the presence of the ATXAb antibody of the patients and controls was determined by the ELISA test. SPSS 20 software was used to perform the statistical analysis (SPSS, inc., Chicago, USA). Results: Out of 130 (35.4%) cases with MS and 130 (13.8%) controls, 46 and 18 subjects were seropositive for ATXAb, respectively. Based on the chi-square test, a significant difference was observed in terms of the positivity rates of ATXAb between the MS patient group and the control group (P = 0.001). The mean ± standard deviation ATXAb levels in controls and MS patients were found to be 61 ± 34 and 114 ± 47 IU/mL, respectively. Also, there were statistically significant differences between the levels of these two groups (P = 0.001). Conclusions: Given the relationship between toxoplasmosis and MS, it is possible that the prevalence of MS decreases by increasing hygiene and preventing toxoplasmosis.

Abstract Objectives: Although in many studies, the relationship between autoimmune hypothyroidism (Hashimoto) and Vitamin D deficiency was shown, no research has been performed on the role of vitamin D in non-autoimmune hypothyroidism. Design: This was a Retrospective case–control study in Endocrinology clinic of Jahrom (south of Iran). The patients with Hashimoto (n=633) and non-Hashimoto hypothyroidism (n=305), along with a control group (n=200) were evaluated. 25(OH)D level, T3 and T4 levels were studied and Anti TPO and Anti TG tests were performed. The results of vitamin D level were analyzed and interpreted using SPSS in terms of the cause of hypothyroidism (immune and non-immune). Results: The results of the study showed a significantly lower level of vitamin D in both immune and non-immune Hashimoto’s thyroiditis (HT) in comparison to healthy controls (P<0.05). We observed a significant inverse correlation between the vitamin D and TGAb level (p=0.001, r=-0.261) and a direct correlation of vitamin D with TSH level (p=0.008, r=0.108) in HT patients. Conclusion: Finally, the results indicated that non-autoimmune hypothyroidism, as well as HT, is associated with vitamin D deficiency. The role of vitamin D deficiency in HT was thought to be in the association of higher autoantibody (TGAb) level; while, there should be further studies determining vitamin D deficiency's role in non-immune hypothyroidism.

Background: Previous studies on the pneumonia outbreak caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have focused on the general population and pregnant women, while little is known about the effects of SARS-CoV-2 on retardation during and after pregnancy. The purpose of this study was to evaluate the potential influence of SARS-CoV-2 on infant neurobehavioral development.Methods: A case-control study was conducted in Wuhan Maternal and Child Health Hospital, China. Nine pregnant women with SARS-CoV-2 infection and 9 controls matched by maternal age, parity, and status of chronic disease were included. Infantile neurobehavioral development was assessed through the Ages and Stages Questionnaires Edition 3 (ASQ-3).Results: The majority of pregnant women with SARS-CoV-2 experienced cesarean section (7 of 9), which was higher than the control group (5 of 9). The throat swabs of all newborn were negative. We found that compared with the control group, neonates of mothers with SARS-CoV-2 infection during pregnancy had lower scores in communication, gross movement, fine movement, problem solving, and personal-social domains; but only fine movement domain yielded statistical significance (P = 0.031).Conclusion: Infection with SARS-CoV-2 during pregnancy may have a certain impact on infant neurobehavioral development. Further studies with larger sample size are warranted for validation.

Background and Objectives: Preterm delivery is an important subject in gynecology, obstetrics and pediatrics. It is defined as regular uterine contractions every five to eight minutes or less, lasting for 30 seconds. It is associated with progressive changes in the cervix, resulting in delivery after 22 weeks and before 37 weeks of gestation. This study aimed to evaluate the role of Chlamydia trachomatis infection in women with preterm delivery. Materials and Methods: This case-control study was performed on 75 women with preterm delivery (case group) and 75 women with term delivery (control group). The research tools included a questionnaire, polymerase chain reaction (PCR) assay of cervical swab samples and ELISA assay of umbilical cord blood samples. Fisher’s exact test and t test were also performed to compare qualitative variables between the two groups. Results: In this study, the mean age of subjects was 26.55 ± 0.53 years in the control group and 26.76 ± 0.56 years in the case group. The prevalence of C. trachomatis in the cervical swab samples was 7 (9.33%) in the control group and 2 (2.67%) in the case group. There was no C. trachomatis IgM antibody in either of the groups, while there was 1 (1.33%) C. trachomatis IgG antibody in both groups. Conclusion: The results of the present study showed that there was no significant relationship between C. trachomatis infection and preterm delivery.

Introduction: Mild pancreatitis is a self limiting disease, while morbidity and mortality is considerably high in cases of severe necrotizing pancreatitis. Octreotide reduces secretion, release and activation of exocrine hormones; there is collection of pancreatic hormones in duct which in return causes irreversible destruction of the exocrine and endocrine pancreatic parenchyma leading to mal-digestion and diabetes. There are lot of controversies in the treatment of acute pancreatitis, so through this study we tried to evaluate whether there is a beneficial role of octreotide or not. Materials and Method: This case control study was done on patients admitted for the treatment of acute pancreatitis at a tertiary care hospital in Central India. This is retrospective study. The data of inpatient records were taken from the medical records department (MRD) of the hospital. The diagnosis of patients was established on basis of biochemical and radiological investigations. The patients were divided into two groups; cases and control, cases had received octreotide along with fluids (group A) controls received fluids without octreotide (group B). Symptomatic treatment was given in both the groups. Ages of the cases and controls were matched (±3 years). The statistical analysis of data was done and results were obtained. Results: In this retrospective case control study the records of fifty two patients were selected. The mean age in Group A was 35 ±16.45 years and in Group B 40±17.51 years in Group B (tA/B1.061; p ˂0.294). There were 22 males and 4 females in group A, while 20 males and 6 females in group B. Both the groups were comparable. All the patients in octreotide group survived while there were three deaths in control group. As far as mean hospital stay is was 10 days ± 7.10 in group A while it was 7 days ±3.65 in group B. All the p values for the criteria of study are non-significant. But when we talk about percentage, 11.53% patient died in control group. Conclusion: In our study we found that octreotide does not affect the final outcome of patients with acute pancreatitis. There is no effect on hospital stay and reduced need of analgesics in patients with acute pancreatitis. Keywords: Acute Pancreatitis; Octreotide; Hospital Stay; Mortality
