Abstract Background Thrombin-activatable fibrinolysis inhibitor (TAFI) inhibits fibrinolysis and high levels may have an association with thrombosis. The aim of the current study was to investigate the association of TAFI antigen levels with pulmonary thromboembolism (PTE). Patients and Methods A case–control study was conducted with 29 patients with PTE and 17 age- and gender-matched control individuals. Plasma levels of TAFI were measured at the time of diagnosis, then at 3 and 6 months after the event. Results Initial TAFI levels (%) were higher in patients with PTE than in the control group Initial TAFI levels (%) were higher in patients with PTE than in the control group (190,0 [65,0–250,0] vs 133,0 [83,0–153,0]; p = 0.003). TAFI levels significantly decreased at the third and sixth months after initial diagnosis (p < 0.05). The percentage reductions in TAFI levels were 12 and 36.8% at 3 and 6 months, respectively. The Odss ratio (OR) of TAFI level for PTE was found to be 1.024 (95% CI: 1.007–1.040; p = 0.005). There was no significant correlation of initial TAFI levels with age, gender, smoking status, history of thrombosis, pulmonary artery pressure, and D-dimer levels (p > 0.05). In the sixth month of treatment, patients with residual thrombosis were seen to have similar baseline levels and reductions of TAFI as patients without residual thrombosis (p > 0.05). Conclusion The result of this study suggests that high TAFI levels may have a role in the occurrence of PTE without impact on treatment outcome.

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.

Background: Addiction is currently one of the problems of human society. Drug abuse is one of the most important issues in the field of addiction. Methamphetamine (crystal) is one of the drugs that has been abused in recent decades. Methods: In this case-control study, 10 individuals aged 20 to 40 years old with at least 2 years of experience of methamphetamine consumption without any history of drug use or other stimulants from clients and drug withdrawal centers in Tehran City, and 10 healthy volunteers were selected. Age, social status, and economic status of addicts were included in the fMRI apparatus, and 90 selected pleasurable, non-pleasurable, and neutral images (IAPS) were displayed by the projector through an event-related method. The playback time of each photo was 3 s, and after this process, the person outside the device, without the time limit selected the enjoyable and unpleasant images. Results: The results showed that there was no significant difference between the groups in terms of age, alcohol use, and smoking history (P < 0.05). There was no significant difference in terms of the age at first use between members of the methamphetamine-dependent group. Also, the methamphetamine-dependent group showed more brain activity in their pre-center and post-center gyrus than the normal (control) group. Conclusions: According to the results obtained in this study, in general, it can be concluded that there are some areas in the brain of addicts that are activated when watching pleasant photos, while these areas are not active in the brains of normal people.

Introduction Optimal management of lower extremity fractures includes early antibiotics administration, thorough irrigation and debridement, consideration of soft tissue injury, and definitive skeletal management. The purpose of this study was to evaluate the efficacy of topical vancomycin powder in the treatment of open lower extremity fractures. Methods This was a retrospective case control study in which open lower extremity fractures at our institution were reviewed for development of infection (including species and sensitivity if present) and the development of unanticipated wound complications requiring intervention. Patients from 2010-2015 were treated with standard of care consistent with evidence-based literature (IV antibiotics with external fixator, intramedullary nail, etc.). Patients from 2016–18 were additionally treated with vancomycin powder applied directly to the wound before closure. All patients were monitored per the treating surgeon’s standard follow-up protocol and had follow-up of at least two months. Results This retrospective case control study comprised 434 patients. The historical control group (n = 388 patients) and treatment group (n = 46 patients) were similar for age, sex, BMI (body mass index), diabetes, smoking status, and Injury Severity Score (ISS). There were 36 infections (9.28%) in the control group compared to four infections (8.70%) in the vancomycin powder group (p = 0.901). No significant difference was seen after adjusting for age, sex, BMI, diabetes, smoking status, and ISS. The vancomycin powder group experienced significantly more wound complications (15.2%) compared to the control group (6.4%; p = 0.039), which remained significant when adjusting for multiple covariates. Conclusions Topical vancomycin powder did not reduce the infection rate when applied in the surgical site of open lower extremity fractures. Instead, the addition of topical vancomycin powder resulted in significantly more wound complications in patients with open lower extremity fractures.

BACKGROUND:Nonalcoholic steatohepatitis (NASH) may progress to cirrhosis. The prevalence and clinical relevance that spontaneous bacterial peritonitis may have in complicating ascites due to NASH-related cirrhosis have yet to be defined.METHODS:Among 611 cases of cirrhosis-associated ascites, 45 patients with cryptogenic cirrhosis were retrospectively identified. Of these, 36 patients and a control group of subjects with viral-associated ascites were followed up and compared in a case control study. Information on the onset of ascites, with or without spontaneous bacterial peritonitis, history of risk factors for multimetabolic syndrome, and serological and ascitic laboratory data were compared between groups.RESULTS:Spontaneous bacterial peritonitis occurred significantly more often in patients with cryptogenic cirrhosis than in equally symptomatic viral controls. The prevalence of obesity, diabetes and spontaneous bacterial peritonitis was significantly higher in patients with cryptogenic cirrhosis. Although liver function was similar in both groups, cryptogenic cirrhosis patients had lower aminotransferase levels. Multivariate analysis identified diabetes, juvenile obesity and spontaneous bacterial peritonitis as independent factors associated with ascites due to cryptogenic cirrhosis.CONCLUSIONS:Features suggestive of NASH are more frequently observed in patients with ascites and cryptogenic cirrhosis than in age- and sex-matched ascitic patients with well-defined viral etiology. Ascites may be a presenting symptom of NASH-related cirrhosis, and affected patients have a twofold greater risk of spontaneous bacterial peritonitis.

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&lt;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.
