Background: The effect of opium addiction (OA) on cerebrovascular disease is controversial. The aim of this study was to clarify this relationship in Iranian patients with ischemic stroke. Methods: In a case-control study, 672 patients with ischemic stroke and 293 controls without a previous history of cerebrovascular or cardiovascular diseases were compared. OA as well as other risk factors such as diabetes mellitus (DM), hypertension (HTN), hyperlipidemia, tobacco smoking (TS) were compared between the 2 groups. Results: OA percentage, TS, TS amount (pack/year), HTN and DM history were significantly higher in the case group compared to controls (p < 0.05). After regression analysis between risk factors, a significant difference remained between 2 groups with regards to HTN (OR 4.21, 95% CI 3.05–5.81, p < 0.001), TS (OR 2.33, 95% CI 1.51–3.59, p < 0.001), and OA (OR 2.36, 95% CI 1.16–4.85, p = 0.018). Conclusion: Our study showed OA is a risk factor for stroke. However, a follow-up study with a larger cohort is required to confirm the results.

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: Epidemiologic studies have reported that microalbuminuria is a risk factor for stroke in men and a limited case control study found that the highest quintile of microalbuminuria values was associated with 13 fold increased risk for stroke. The goal of this study is designed to determine its relationship to risk factors for ischemic stroke. Materials and Methods: It was a prospective observational study conducted in the Department of Neurology, Sir Salimullah Medical College Mitford Hospital, Dhaka, Bangladesh. Fifty consecutive patients with ischemic stroke with at least two risk factors who fulfilled the inclusion criteria of case were confirmed by CT or MRI. Equal number of controls same ages without stroke who had at least two risk factors were compared with the case group. The patients were assessed clinically with structured questionnaire including blood pressure, height and weight, and monitoring blood glucose and microalbuminuria. Results: Microalbuminuria was found 58.0% in patients with ischemic stroke. Patients who had diabetes mellitus will have 13.86 times the risk for developing microalbuminuria (p<0.05). Patients who had HTN will have 4.19 times the risk for developing microalbuminuria (p<0.05) and BMI (?23 kg/m2) will have 4.24 times the risk for developing microalbuminuria with (p<0.05). Whereas TIA, IHD, dyslipidemia, smoking and positive family history were not significantly (P>0.05) associated with microalbuminuria in patients with ischemic stroke. Conclusion: The findings of this study show that diabetes is the factor most closely associated with microalbuminuria followed by HTN and BMI?23 kg/m2 with statistically significance in patients with ischemic stroke.

AIMS: To investigate the associations between breast cancer diagnosis and nutritional and environmental factors in women from Northeast Brazil.METHODS: A case-control study included women evaluated in two hospitals specialized in cancer treatment. The case group was composed by women with breast cancer whose data were obtained during the hospitalization period for surgical treatment of the disease. The control group was selected in the same hospitals excluding the oncology ward. The following risk factors were investigated: household environmental sanitation, breastfeeding history, social class, smoking exposition, alcohol consumption and family history of cancer. A food frequency questionnaire was completed by the subjects and an evaluation of anthropometric nutritional status was made. Comparison for quantitative variables was performed using independent t-test or Mann-Whitney test. Chi-square or Fisher's exact test were used to compare categorical variables. The estimated risk associated with consumption of nutrients and food groups was assessed by OR, with a 95% confidence interval. In order to assess the effect of possible confounding factors such as excess weight or excessive caloric intake, a multivariate analysis was performed with the variables with p<0.15 in the food consumption analysis. The significance level for all analyses was set at p<0.05.RESULTS: The total sample consisted of 118 women, 59 in each group. Of all environmental risk factors investigated, poor sanitation (OR [odds ratio]=3.2, 95%CI 1.43-7.11) and family history for cancer (OR=3.11, 95%CI 1.42-6.78) were significantly associated with the diagnosis of breast cancer. Regarding anthropometric assessments, overweight or obesity and waist circumference >88cm were more prevalent in the case group (OR=2.70, 95%CI 1.28-5.70 and OR=3.10, 95%CI 1.46-6.56, respectively). Regular consumption of ultra-processed foods was identified as a risk factor for breast cancer (adjusted OR=2.35, 95%CI 1.08-5.12).CONCLUSIONS: Higher consumption of ultra-processed food, presence of overweight or obesity, waist circumference ≥88 cm, poor sanitation, and family history of cancer were risk factors for breast cancer in this sample of women living in Rio Grande do Norte state, Brazil.

Introduction: Ectopic pregnancy is a significant cause of maternal mortality and morbidity during the first trimester. The major risk factors for ectopic pregnancy include prior tubal infections, previous ectopic pregnancy, previous abortions, use of intrauterine contraceptive devices, contraception failure, tubal surgeries, infertility and use of artificial reproductive pregnancies. This study was carried out to evaluate the effect of different risk factors in the causation of ectopic pregnancies among women in the Nepalese setting. Materials and methods: This was a case-control study conducted at Kathmandu Medical College comparing 39 cases of ectopic pregnancies with 39 controls consisting of intra-uterine pregnancies. The suspected cases were confirmed through clinical examination, trans-abdominal or trans-vaginal ultrasonography and serum β-hCG levels with further confirmation obtained after laparotomy / laparoscopy among cases who underwent surgery. The two study groups matched with age, gravidity and contraceptive uses were studied. History of previous abortions, previous ectopics and past abdomino-pelvic surgeries were also studied. Results: There was statistically significant difference in the incidence of contraceptive failure among the two groups (p-value= 0.032) with women with such history having a relative risk of 1.667 with odds ratio of 3.400. The risk posed by previous abortions and previous ectopics wasn’t found significant (RR= 1.000 and 2.053 respectively). The history of past abdomino-pelvic surgeries also showed significant role in causation of ectopics (RR= 1.094). Conclusion: Among different risk factors studied, the contraception usage was the most significant risk factors. Oral contraceptive pills was the most identified among the contraception used in cases of ectopic pregnancy.

Oral pathogens have been identified in bioptic specimens from Age-Related Macular Degeneration (ARMD) patients, and alveolar bone loss has been related to ARMD. Therefore, the possible association between ARMD and periodontal disease was investigated in the present case-control study, evaluating clinical and radiographic periodontal parameters, primarily, in cases vs. controls and, secondarily, in relation to ARMD risk factors, in cases, to highlight a possible pathogenic link between the disorders. Forty ARMD cases and 40 non-ARMD controls, matched for age (±3 years) and gender and homogeneous for ARMD risk factors, therefore comparable, underwent full-mouth periodontal charting, panoramic radiograph, and medical data, including ARMD risk factors, collection. Statistical analysis was conducted using the language R. Comparisons between groups were made using both traditional t-tests and Yuen’s test with bootstrap calibration. Enrolled subjects were ≥55 years old, and 50 females and 30 males were equally distributed among the two groups. No statistically significant difference was found in clinical and radiographic periodontal parameters in cases vs. controls. In the case group, no differences were found when relating the periodontal parameters to ARMD risk factors, except for Clinical Attachment Level values that were statistically significantly higher in hypertensive ARMD subjects. A possible association between periodontal disease and ARMD may be hypothesized in hypertensive ARMD subjects, with hypertension as a possible pathogenic link between the disorders.

Abstract Background Previous studies have shown the association between Campylobacter species infection and that environmental factors, poor oral hygiene in particular, are linked to an increased risk of esophageal cancer (EC). However, no study has reported on these factors in Thailand. Thus, this study’s objective was to evaluate the impact of the relationship between Campylobacter infection and environmental factors on EC incidence in the population of Thailand. Methods Data from a case–control study were collected from 105 newly diagnosed EC cases and 105 controls recruited from 2007 to 2017. Infection with Campylobacter spp. was detected in the formalin-fixed paraffin-embedded (FFPE) tissue of EC taken from gastroesophageal biopsy specimens obtained from the participants, and evaluated using TaqMan® real-time PCR. Multivariable logistic regression was performed to calculate the odds ratios (ORs) and perform data analysis. Results Smoking, alcohol use, a family history of cancer, history of gastroesophageal reflux disease, poor oral hygiene and Campylobacter spp. infection were shown to be significant risk factors for EC (p  <  0.05). The combination of poor oral hygiene and infection with Campylobacter spp. constituted significant risk for EC (p  <  0.001). In addition, the risk of EC in subjects co-infected with C. rectus and C. concisus that practiced poor oral hygiene was even higher and was significant (ORadj  =  4.7; 95% CI 2.41–9.98; p  =  0.003). Conclusions In Thailand, the major risk factors for EC are smoking status, alcohol drinking, family history of cancer, GERD, poor oral hygiene and Campylobacter spp. infection. This study found Campylobacter spp. prevalence to be associated with EC and appears to be enhanced by poor oral hygiene, suggesting that a combination of poor oral hygiene and Campylobacter species infection may together act as an important etiological risk factor for EC.

This study was conducted to assess and compare the cardiovascular risk and to explore the demography of CV risk of nonselective cyclooxygenase inhibitors (COX-Is) and selective COX-2-Is in arthritic patients. In this comparative matched case control study adult arthritic patients of either sex taking COX-Is for >1 yr; were included. Arthritic age and sex matched individuals with no history of COX-Is treatment were the controls. Patients those with history of any other disease (e.g. diabetes, hypertension, stroke, IHD etc.) were excluded. Patients were grouped into Control, nonselective COX-I and selective COX-2-I groups. The CV risk factors like blood pressure, blood sugar level(BSL), lipid profile, BMI(body mass index) etc. were assessed and compared; demography of CV risk factors i.e. age, sex, smoking, alcohol, heredity was also studied. Qualitative data was analyzed using Chi-square and quantitative data was analyzed by student’s‘t’-test. Study clearly revealed that all NSAIDs exhibit significant CV risk when taken over a period of time as in arthritis. However selective COX 2-Is found to exhibit more CV risk in this regard. Odds ratio (OR) for CV risk=10.3(95% CI: 1.45, 3.31) and OR for CV risk=5.2(95%CI: 1.05, 2.57) for nonselective COX-Is. BMI, BSL and lipid profile; the potential CV risk factors, showed significant impairment in selective COX 2-Is group; P<0.05, P<0.05 and P<0.01 (HDL), P<0.001 (cholesterol), respectively compared to controls and P<0.05 compared to nonselective COX-Is. This study portrays the potential CV risk of selective COX 2-Is and confirms and re-evaluate the results of earlier studies in this regard.  Keywords: Anti-arthritic agents; BMI; COX-Is; CV risk; Lipid profile.  © 2014 JSR Publications.

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.
