Abstract Background Preeclampsia is a global health problem and it is the main cause of maternal and perinatal morbidity and mortality. Breastfeeding has been reported to be associated with lower postpartum blood pressure in women with gestational hypertension. However, there is no published data on the role that breastfeeding might play in preventing preeclampsia. The aim of the current study was to investigate if breastfeeding was associated with preeclampsia in parous women. Method A case-control study was conducted in Saad Abualila Maternity Hospital in Khartoum, Sudan, from May to December 2019. The cases (n = 116) were parous women with preeclampsia. Two consecutive healthy pregnant women served as controls for each case (n = 232). The sociodemographic, medical, and obstetric histories were gathered using a questionnaire. Breastfeeding practices and duration were assessed. Results A total of 98 (84.5%) women with preeclampsia and 216 (93.1%) women in the control group had breastfed their previous children. The unadjusted odds ratio (OR) of preeclampsia (no breastfeeding vs breastfeeding) was 3.55, 95% confidence interval (CI) 1.64,7.70 and p value = 0.001 based on these numbers. After adjusting for age, parity, education level, occupation, history of preeclampsia, history of miscarriage, body mass index groups the adjusted OR was 3.19, 95% CI 1.49, 6.82 (p value = 0.006). Conclusion Breastfeeding might reduce the risk for preeclampsia. Further larger studies are required.

Childhood Caries

Objective: The aim of this study was to determine the risk factors associated with early childhood caries (ECC).Methods: It was an observational retrospective case-control study. The case group consisted of all patients diagnosed with ECC in the records of an active program of maternal and child care. The control group was composed of an equal number of children, matched for gender and age, who attended the program and did not have ECC. The process of data collection consisted of completing a pre-established schedule to analyse variables related to the mother/caregiver and child.Statisticalanalysis was performed using the chi-squared and odds ratio (OR), with alpha (α) = 0.05.Results: History of caries in the mother (OR=2.61; CI 95%=1.45-4.67) and father (OR=1.72; CI 95%=1.02-2.89) were key determinants in the child being diagnosed with ECC.Conclusions: The risk factors associated with ECC were the following: no oral hygiene acceptance, nocturnal feeding duration of more than 16 months, a daily intake of sugar greater than 4 times a day, a Baume type II maxillary arch, fewer than 3 consultations with the program, and a history of decay in the parents.

10012 Background: Some prospective studies in US and UK (represented by Women’s Health Initiative and Million Women Study) show that HRT use may increase the risk of breast cancer. However, it is unclear whether or not this perspective is applicable to Japanese women, due to several factors such as the difference in incidence of breast cancer, difference in HRT prevalence, which are to be concerned in this study. To investigate the relationship between HRT use and breast cancer, a case-control study was conducted in Japan. Methods: We sent self-administered questionnaire to 4,500 cases who have a previous history of confirmed histological breast cancer and 4,500 controls who were selected according to the inclusion criteria. All the subjects were between age 45 and 69 at the time of enrollment. Among these subjects, 3,434 in case group and 2,427 in control group sent back their questionnaire (total 5,861). The datacenter was run in Kitasato Univ. and the statistical analysis was performed using SAS (version 9.1). Control was selected by considering the screening record for GI disease and respiratory disorders, with no previous history of breast cancer, gynecological and hormonal disease at the time of screening. We asked about past history of exposure to the factors supposed to be breast cancer-causing; previous or current use of HRT, age at diagnosis, academic background, BMI, lifestyle habits, age of menarche, birth history, history of breast feeding, family history, use of contraceptive agents and menopausal status. Results: As the main analysis result, 164 (5.0%) out of 3,316 cases and 253 (7.4%) out of 2355 controls had used HRT (Odds ratio 0.432 [95% CI 0.352–0.530]. Conclusions: The result of this study shows that HRT users were less likely to develop breast cancer than never users. However, in this study, there was a difference in the observation period for the past use of HRT between cases and controls. Considering the transition of HRT prevalence in Japan, there may be a possibility that this difference can be a cause of a serious bias for the main analysis result. Further sensitivity analyses are needed to evaluate the robustness of the findings and this point is under consideration. No significant financial relationships to disclose.

BackgroundThe association of complications of pregnancy and the risk of developing gynecological cancer is controversial with the limited study. In this study, we investigated the association of preeclampsia, or gestational diabetes mellitus (GDM), or large for gestational age (LGA), or intrauterine growth restriction (IUGR) and the risk of endometrial or ovarian cancer.MethodsIn this case-control study, 189 women with endometrial cancer and 119 women with ovarian cancer were included. 342 women without gynecological cancers were randomly selected as a control group. Data on the history of pregnancy and age at diagnosis of gynecological cancer as well as the use of intrauterine devices (IUDs) were collected.ResultsWomen with a history of preeclampsia or IUGR did not have an increased risk of developing endometrial or ovarian cancer. While women with a history of GDM or with the delivery of LGA infant increased the risk of developing endometrial cancer but not ovarian cancer. The odds of women with a history of GDM or with the delivery of LGA infant developing endometrial cancer was 2.691 (95% CI: 1.548, 4.3635, p=0.0003), or 6.383 (95% CI: 2.812, 13.68, p<0.0001) respectively, compared to the controls. The odds ratio of women who did not use IUDs developing ovarian cancer was 1.606 (95% CI: 1.057, 2.434), compared to the controls. There was no association of age at first birth and developing endometrial or ovarian cancer.ConclusionOur observational data suggested that GDM and delivery of an LGA infant are associated with an increased risk of endometrial cancer.

Abstract Background: Acute pancreatitis (AP) is a common inflammatory disorder of the pancreas. Recent evidence has shown that metabolic syndrome is positively correlated with the severity of AP. However, only a few studies have revealed the relationship between metabolic syndrome and the occurrence of AP. We therefore elucidated the association between metabolic syndrome and the occurrence of AP. Methods: A hospital-based case-control study was conducted. A total of 705 patients admitted to our hospital from January 2016 to December 2018 were included in the study. Subjects were divided into case and control groups according to their diagnosis: (1) According to the revised Atlanta classification from 2012, patients diagnosed with AP were enrolled in the case group. (2) Patients without a history of AP or any disease related to metabolic syndrome were allocated into the control group. Controls were matched to cases individually by sex and age (control/case ratio=1). Results: The incidence rate of metabolic syndrome in AP patients was 30.9%, which was more frequent than that in controls (13.2%) (OR=2.837; 95% CI 1.873-4.298, p<0.001). In the multivariate regression analysis, a history of smoking or alcohol consumption and biliary stones were significantly associated with AP (OR=2.441; 95% CI 1.865-5.172, p<0.001; OR=1.777; 95% CI 1.060-2.977, p=0.029; OR=28.995; 95% CI 13.253-63.435, p<0.001). In addition, the occurrence of AP was significantly associated with total cholesterol (TC) (OR=1.992; 95% CI 1.246-3.183, p=0.004), triglyceride (TG) (OR=2.134; 95% CI 1.403-3.245, p<0.001), hyperglycaemia (OR=2.261; 95% CI 1.367-3.742, p=0.001), and apolipoprotein A (Apo A) (OR=0.270; 95% CI 0.163-0.447, p<0.001). Conclusions: Metabolic syndrome and its components were associated with AP occurrence.

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.

Background.Recent data have suggested that polymorphisms in the length of the polyalanine tract (polyA) ofFOXE1gene may act as a susceptibility factor for thyroid dysgenesis. The main purpose of this study was to investigate the influence of polyA ofFOXE1gene on the risk of thyroid dysgenesis.Method.A case-control study was conducted in a sample of 90 Brazilian patients with thyroid dysgenesis and 131 controls without family history of thyroid disease. Genomic DNA was isolated from peripheral blood samples and the genotype of each individual was determined by automated sequencing.Results.More than 90% of genotypes found in the group of patients with thyroid dysgenesis and in controls subjects were represented by sizes 14 and 16 polymorphisms in the following combinations: 14/14, 14/16, and 16/16. Genotypes 14/16 and 16/16 were more frequent in the control group, while genotype 14/14 was more frequent in the group of patients with thyroid dysgenesis. There was no difference between agenesis group and control group. Genotype 14/14 when compared to genotypes 14/16 and 16/16A showed an association with thyroid dysgenesis.Conclusion.PolyA ofFOXE1gene alters the risk of thyroid dysgenesis, which may explain in part the etiology of this disease.

Introduction: Anti-tuberculosis drugs can cause adverse reactions including hepatitis and skin reactions. This case control study was aimed at fi nding out whether allergy to drug or food acts as a risk factor for the development of anti-tuberculosis drug induced hepatitis or skin reactions. Patients with tuberculosis on category 1 regimen, who presented to the Teaching Hospital Kandy Sri Lanka, due to anti-tuberculosis drug induced hepatitis or skin reactions from 1st July 2010 to 30th June 2011 were recruited. Methodology: Patients with drug induced hepatitis or skin reactions were grouped as cases and patients who didn’t develop hepatitis or skin reactions during the treatment period were selected as controls. Controls were matched for age, gender, weight, and consumption of alcohol. Cases and controls were inquired for the presence of allergy to drugs or food. Two groups were compared using odds ratio. Results: There were 61 cases [33 (54.1%) males, 28 (45.9%) females] and 61 controls .Ten patients (16.39%) among the cases had allergy to food or drugs while in control group only 2 (03.2%) had allergy. Odds ratio for the development of drug reactions in patients with a history of allergy was 5.8 (confi dence interval 1.2 to 27.6). Conclusion: Patients with allergy to drugs or foods have 5.8 times risk of developing anti-tuberculosis drug induced hepatitis or skin reaction.

Introduction: The opinion that latent T. gondii infection is having a broadly asymptomatic projection has now been interrogated, in specific due to the echoed association between the latent infection and an elevated incidence of schizophrenia or even suicide attempts. Notwithstanding conducted studies aimed to understand this feasible link are restricted. Methods: In the present case-control study, we focused to illuminate the relationship between the serological and molecular presence of T. gondii and schizophrenia with or without the suicide attempts by comparing it with healthy individuals. A total of 237 participants (117 in schizophrenia; 120 in healthy control) were included in this study. Results: Overall, latent T. gondii infections were found statistically higher in 63 (53.8%) of the 117 patients with schizophrenia and in 33 (27.5%) of the 120 controls (p < 0.001). In schizophrenia patients, seroprevalence T. gondii was again found to be statistically higher in suicide attempters (59.6%), compared to no history of suicide attempts (48.3%) (p < 0.05). The molecular positivity rate of T. gondii DNA was higher in the schizophrenia group, compared to the healthy control group (p < 0.05), whereas the history of suicide attempts was not statistically associated (p = 0.831) with T. gondii DNA positivity by PCR. Conclusion: This case-control study enlightens additional demonstration to the belief that T. gondii infection would be an underlying component for the pathophysiology of schizophrenia. Regardless of the clarity results of this study, this supposition warrants further endorsement.

Background/Aim. Malignant gliomas represent a heterogenaus group of tumors. They occur in all age groups, predominatly in males in older age. The purpose of this case-control study was to examine the association between risk for developing glioma and family history of diseases. Methods. The case-control study included 100 pathologically confirmed cases of glioma at the Clinical Centre Kragujevac, Serbia, between 2015 and 2016, and 200 ageand sex-matched controls without glioma and other malignant diseases in personal and family history at the same institution. After signing the informed consent all the patients filled out an epidemiological questionnaire. Multivariate logistic regression analysies was used in statistical data processing. Results. Malignant diseases in family history were more common in the study group than in the control group [odds ratio (OR) = 1.821, 95% confidence interval (CI) 1.004?3.305; p = 0.049]. The most common malignant tumor in the study group were cancer of the uterus (7%) and colon cancer (6%), while in the control group the most common cancer were lung cancer (6%) and cancer of the uterus (7%). Diabetes mellitus in family history was more common among control individuals than among glioma patients (OR = 0.520, 95% CI = 0.271? 0.995; p = 0.048). Also, our results showed that cardiovascular diseases in family history were more common in the control group than among patients of the study group (OR = 0.557, 95% CI = 0.325?0.953; p = 0.033). Conclusion. In this case-control study, we observed a statistically significant relation between family history of malignant diseases and glioma. Also, we found statistically significant inverse relation between family history of cardiovascular diseases and diabetes and glioma.

Objective: To identify the effect of hormonal contraceptive exposure to the occurrence of meningioma.Materials and Methods: This study, conducted in 2016, was a case-control study by collecting a group of cases comprising all patients diagnosed histopathologically with meningioma in 2012-2013 and treated in dr. Soetomo Hospital, Surabaya, Indonesia. Medical record data were analyzed and compared to control group of patients diagnosed with non-meningioma who underwent contrast head ct scan and direct interviews. We obtained 101 cases and 101 controls. Data were analyzed using univariate logistic regression test.Results: Based on the history of hormonal contraceptive use, patients who had history of hormonal contraceptive use had 12.31 times higher risk (p=0.000). In this study, those who had contraceptive injections for one month and used contraceptive pills had a meningioma risk lower than those who used injectables 3 months. Patients who used hormonal contraception more than 10 years had an increased risk for meningioma as much as 18.216 times (p=0.000). Histopathologically, we found a non-significant association between history of hormonal contraceptive use and the distribution of histopathology, but based on descriptive data showed it was found that the most histopatological meningioma was of the transitional type in cases group.Conclusion: There is a significant association between hormonal contraceptive use, the type of injectable hormonal contraception for 3 months, the duration of hormonal contraceptive use >10 years, and no significant association between meningioma grade and the history of hormonal contraception exposure.
