Abstract Background Several studies have identified different genes that control the final dimension and structure of the mandible. Prognathism of the mandible is thought to correlate with these genes; however, no specific gene has been assigned as a risk factor due to various genome-wide scan results in different races. Previous studies that involved the Han ethnic group in China and Korea suggested matrilin-1 (MATN1) polymorphism as the contributor for mandibular prognathism. To date, no study has been conducted to understand the role of MATN1 in Deutero-Malay population. This study aimed to detect MATN1 gene polymorphism in the promoter and exon 5 regions, which is a proposed risk factor in class III skeletal malocclusion with mandibular prognathism in Deutero-Malay population. This was a case-control study with purposive sampling method that involved 47 class III skeletal malocclusion subjects with mandibular prognathism (case group) and 47 class I skeletal relation subjects (control group) performed in the Molecular Genetics Laboratory of Faculty of Medicine, Universitas Padjadjaran, Indonesia. DNA isolated from buccal mucous epithelia and MATN1 gene was amplified using the polymerase chain reaction (PCR) and sequencing technique. Data were then analyzed statistically to observe the frequency of allele/genotype MATN1 in class III skeletal malocclusion and mandibular prognathism patients in comparison with the normal mandibular as well as to identify the risk factor of mandibular prognathism. Result The frequency of the 354 T > C(rs20566) CC genotype gene polymorphism in the case group was significantly higher than in the control group. The odd ratio (OR) value of the case group was also higher than in the control group (χ2 = 4.89; p = 0.027; OR = 6.27). Conclusions Our results show that the polymorphism of 354 T > C in the exon 5 region of the CC genotype MATN1 gene is a risk factor for class III skeletal malocclusion with mandible prognathism in Deutero-Malay population.

Abstract Background: Ectopic pregnancy (EP) is defined as a pregnancy in which fertilized oocyte implants outside the endometrial cavity. Although there is no known etiology for ectopic pregnancy, some risk factors of EP have been determined. It has been evident that ectopic pregnancy can be of multifactorial origin. This multicenter research aims to study risk factors associated with increased risk of ectopic pregnancy in women living in Kabul. Methods: A multicenter case control study was conducted in five tertiary maternity hospitals located in Kabul, Afghanistan. A total of 457 pregnant women were included in this study. In the case group, women with diagnosed ectopic pregnancy, while in control group women with intrauterine pregnancy were included. For each case in this study, two controls were enrolled. Results: The mean (SD) age of women in case group was 27.9 (6) years while in control group it was 26.4 (5.5) years. This difference was not statistically significant. We found a significant association between history of abortion and EP (Adj. OR=1.57; 95%CI: 1.02, 2.42). Having history of abdominal/pelvic surgery was a risk factor for EP with adjusted OR 1.94 (95%CI: 1.15, 3.30). In this study we found an increasing risk of EP in women of 35 years or older compared to younger women (Crude OR=2.26; p= 0.024). In women reporting prior EP, the chance of its recurrence was increased (Crude OR= 9.64; 95%CI: 1.1, 83.2). No association of gravidity and parity was found with EP incidence. Conclusions: In this study we found a statistically significant association between history of abdominal/pelvic surgery and EP. In addition, history of abortion was suggested as a risk factor for ectopic pregnancy. In case of having a previous EP probability of its recurrence will be increased. Women with advanced age having other potential risk factors will be facing higher risk of EP.

Aim:  To study the role of probiotics in controlling chronic kidney disease progression. Sample: To correlate renal parameters like creatinine, urea, uric acid, PCR in patients with chronic kidney disease. Study Design: It is a Prospective case control study Place and Duration of the Study: Department of Nephrology, Santhiram Medical college and General Hospital, between December 2020 – May 2021. Methodology: We included 150 patients with chronic kidney disease from in and out patient departments. In this study patients are divided into two groups; case and control group. Control group is treated with normal conventional therapy whereas the case group is treated with conventional therapy along with probiotics. The lab parameters like creatinine, PCR, urea, uric acid were analyzed before and after the therapy in both groups. Results: The lab parameters were analyzed by paired student`s t- test and the p value of these parameters were found to be in control group creatinine ranges from (4.42+/- 2.84 to 3.54+/- 2.73) and in case/ interventional group creatinine ranges from (5.13+/-2.43 to 2.29+/-1.57) shows <0.001. It shows significant improvement in these parameters in both control and case group. CKD stages were analyzed by Chi- square test, the p value of CKD stages in case group was found to be <0.0001 and in control group it was found to be 0.03. Conclusion: It shows that there is significant improvement is found in both interventional (case) and non-interventional (control) groups. But more betterment is observed in case group than in control group. Hence probiotics are used as a natural bio-treatment to control the progression of CKD and improves the quality of life.

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.

Based on the data from the Central Bureau of Statistics in 2014, the population of the elderly reached 20.24 million or 8.03% of the whole Indonesian people. The older a person is, the more vulnerable he is to degenerative diseases, and one of them is dyslipidemia. The objective of the research was to find out the risk factor for the incidence of dyslipidemia and to determine the value of Odds Ratio of risk factor for dyslipidemia. The research used case-control study design. The data were gathered from patients’ medical records and from the respondents. The samples were 135 respondents with 45 of them were in case group and 90 of them were in control group. The result of bivariate analysis showed that all independent variables were correlated with the incidence of dyslipidemia (p<0.05). The result of multivariate analysis showed that the variable which had the most dominant correlation  was smoking habit at p-value = 0.000 (p<0.05) and OR-value = 9.929 (85% CI 3.428-28.762) which indicated that smoking habit was the most influential risk factor for the incidence of dyslipidemia in the elderly. Keywords: The Elderly, Dyslipidemia, Gender, Obesity, Diabetes Mellitus, Smoking

Background: Premature rupture of membrane (PROM) remains a problem in obstetrics, the mechanisms of PROM have not been clearly defined. Apoptosis is thought to play a key role in the mechanism, via caspase-dependent and caspase-independent pathways. Caspase-3, Apoptosis-inducing factor (AIF), and anti-apoptosis B-cell lymphoma 2 (Bcl-2) are hypothesized to be involved in PROM. Objective: To determine the role of caspase-dependent and caspase-independent pathways in the mechanism of PROM. Materials and Methods: This was a case-control study involving 42 pregnant women with gestational age between 20-42 wk. Participants were divided into the case group (with PROM) and control group (without PROM). Amniotic membranes were collected immediately after the delivery, and samples were taken from the site of membrane rupture. Immunohistochemical examination was done to determine the expression of Caspase-3, AIF, and Bcl-2. Results: The expressions of Caspase-3 (OR = 9.75; 95% CI = 2.16-43.95; p = 0.001) and AIF (OR = 6.60; 95% CI = 1.48-29.36; p = 0.009) were significantly increased, whereas, Bcl-2 expressions (OR = 8.00; 95% CI = 1.79-35.74; p = 0.004) were significantly decreased in the case group. Conclusion: High Caspase-3, AIF, and low Bcl-2 expression were the risk factors for PROM. Thus, it is evident that caspase-dependent and caspase-independent pathways are involved in the mechanism of PROM. Key words: Premature, Membrane, Apoptosis, Caspase, Pregnancy.

<b><i>Aim:</i></b> The aim of this study is to examine possible associations between the transfusion of RBC or platelets (PLTs) and the development of retinopathy of prematurity (ROP) in infants. <b><i>Methods:</i></b> This retrospective, national, case-control study included all live births in Switzerland between 2013 and 2018. We investigated preterm infants at a gestational age of &#x3c;28 weeks, who developed higher stage ROP (≥stage 2, <i>n</i> = 178). Each case infant was matched to another of the same sex who did not develop ROP (<i>n</i> = 178, control group). <b><i>Results:</i></b> When compared with the control group, we observed higher numbers of RBC transfusions per infant and higher percentages of infants receiving PLT transfusions in the case group. An adjusted logistic regression analysis revealed that both RBC (odds ratio [OR] 1.081, 95% confidence interval [CI] 1.020–1.146) and PLT transfusions (OR = 2.502, 95% CI 1.566–3.998) numbers were associated with ROP development. <b><i>Conclusions:</i></b> Multiple RBC and PLT transfusions are associated with higher stage ROP development. Prospective studies are required to determine their potential as risk factors.

Abstract Background In March 2020, the US Food and Drug Administration decided that the dangers related to neuropsychiatric events (NPEs) of montelukast, one of the leukotriene modifying agents (LTMAs), should be communicated through ‘boxed warning’. In case of NPEs, the prevalence has been the highest in elderly people. Because the characteristics of the elderly such as old age itself can act as risk factors. Therefore, an investigation on safety of LTMAs related to NPEs in elderly using LTMAs is needed. Method A nested case-control study using an elderly sample cohort from the Korean National Health Insurance Service database was used. The asthma cohort included asthma patients newly diagnosed between 2003 and 2013. Within the asthma cohort, the case group was defined as patients who were diagnosed with NPEs. Among patients who had never been diagnosed with NPEs, the control group was selected by matching 1:1 by propensity score. Patients who were prescribed LTMAs for 1 year prior to index date were defined as the exposure group. The logistic regression model was used to measure the effect of LTMAs on NPEs. Results We identified 141,165 patients with newly diagnosed asthma, and selected 31,992 patients per each case and control group. Exposure to LTMAs significantly increased the risk of overall NPEs about in comparison with the absence of exposure (crude odds ratio [OR] 1.58, 95% CI 1.50–1.68). After adjusting for confounding factors, the overall NPEs risk increased (adjusted OR, 1.67, 95% CI 1.58–1.78). Conclusion This study suggests that elderly asthma patients prescribed LTMAs had a higher risk of NPEs than patients who were not treated with LTMAs. Therefore, clinicians should be aware of the potential risks of LTMAs.

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.
