e23052 Background: Improved survival rates from cancer have increased the need to understand the health related problems of cancer treatment. Persistent oral health related problems significantly affect patient's quality of life. Medication-related osteonecrosis of the jaws (MR-ONJ) is an oral complication of antiresorptive medications, denosumab and other medications that target angiogenesis for the management of metastatic bone cancer. The purpose of this pilot study, is to investigate, for the first time, microRNAs expression in MR-ONJ. Recent studies reported the miRNA-210 (a specific angiogenic-related miRNA) demethylation in the Osteonecrosis of the Femoral Head. We hypothesized that MiRNA-210 could also be involved in MR-ONJ development. Primary objective of the study is to investigate the role of miRNA-210 in MR-ONJ pathogenesis. Secondary objective is to investigate the feasibility of salivary miRNAs detection as potential non invasive biomarkers for MR-ONJ. Methods: A case-and-control study has been designed. Inclusion criteria are malignant tumors with ongoing treatment or previous history of anti-resorptive or anti-angiogenic medications. The predictor variable is the presence or absence of MR-ONJ. Oral examination and dental x-ray examinations suggestive of MR-ONJ will be performed. Saliva sample will be collected according to the protocol by Navazesh. The methylation status of miRNA-210 will be investigated using quantitative PCR (Q-PCR). Values will be compared between case and control group. Results: The main expected results are to enroll approximatively twenty patients in case group and sixty patients in control group within a one year recruitment period, validate that saliva is a medium for the identification of biomarkers associated with MR-ONJ and confirm the hypothesis that miRNA-210 is involved in MR-ONJ development. Conclusions: Results acquired within this project would represent a contribute to the understanding of the molecular mechanisms driving to the development of MR-ONJ lesions. MiRNA-210 demethylation could serve as a potential therapeutic target for the treatment of MR-ONJ through stimulation of angiogenesis.

Objective: Though preeclampsia (PE) is an age-old disease, its pathology still remains obscure. Available epidemiological evidences suggest that PE is a disease of multiple theories. Recently serum homocystine level is considered as factor to be associated with preecampsia and the higher the level the greater is the severity of preeclampsia. The present study is aimed at investigating this hypothesized association. Methodology: This case-control study was conducted over a period of 24 months from January 2012 to December 2013 in the Department of Obstetrics & Gynaecology, Dhaka Medical College, Dhaka. Pregnant women admitted with severe preeclampsia were the case, while pregnant women attending at the antenatal clinic without preeclampsia were the controls. Severe preeclampsia was diagnosed by blood pressure > 160/110 mm of Hg with proteinuria 3+ or more in dipstick test. The control group comprised of women of 24 - 40 weeks gestation, with blood pressure (both diastolic and systolic) remaining within normal limits without having any medical or obstetric complications. Data were analysed using software SPSS (Statistical Package for Social Sciences) version 16.0. The test statistics used to analyse the data were descriptive statistics, Chi-square (χ2) Test, Student’s t-Test and Receiver-operating characteristic (ROC) curve analysis. Result: Around two-thirds of the patients in both groups were in the age range of 21-30 years with mean age of the cases and control being 25.8 ± 5.2 and 24.1 ± 3.7 years respectively (p = 0.108). Over three-quarters (77.5%) of the patients in case group and 60.0% in control group belonged to middle class (p = 0.091). Majorities of the cases (85.0%) and controls (90.0%) were preterm (gestational age < 37 weeks) with mean gestational age being 33.2 ± 3.3 and 32.3 ± 3.5 weeks in case and control groups respectively (p > 0.05). The patients in either group were predominantly primigravida. Seven (17.5%) patients in the case group gave the history of past preeclampsia as opposed to none in the control group (p = 0.005). Family history of preeclampsia was reported by the case group alone (p = 0.027). Majority (95.0%) of the cases had 3+ proteinuria. Serum homocystine concentration was significantly raised (15.7 ± 8.3 μmol/L) in case group than that in the control group (6.7 ± 1.3 μmol/L) (p < 0.001). Based on the receiver-operator characteristic (ROC) curve, serum homocysteine levels in pregnant women had the best area under the curve (0.975 or 97.5%) with sensitivity and specificity of the predictor variable being 92.5 and 77.5% respectively. Conclusion: The study concluded that homocysteine levels are significantly elevated in patients with preeclampsia compared to the pregnant women without preeclampsia. Homocysteine may be of value in the monitoring of pregnancies to be complicated by preeclampsia. Ibrahim Card Med J 2015; 5 (1&2): 54-60

Abstract Background DNA methylation is an epigenetic process for modifying transcription factors in various genes. Methylenetetrahydrofolate reductase (MTHFR) stimulates synthesis of methyl radical in the homocysteine cycle and delivers methyl groups needed in DNA methylation. Furthermore, numerous studies have linked gene polymorphisms of this enzyme with a larger risk of recurrent pregnancy loss (RPL), yet scarce information is available concerning the association between epigenetic deviations in this gene and RPL. Hypermethylation at precise DNA sequences can function as biomarkers for a diversity of diseases. We aimed by this study to evaluate the methylation status of the promoter region of MTHFR gene in women with RPL compared to healthy fertile women. It is a case–control study. Hundred RPL patients and hundred healthy fertile women with no history of RPL as controls were recruited. MTHFR C677T was assessed by polymerase chain reaction-restriction fragment length polymorphism (RFLP). Quantitative evaluation of DNA methylation was performed by high-resolution melt analysis by real-time PCR. Results The median of percentage of MTHFR promoter methylation in RPL cases was 6.45 [0.74–100] vs. controls was 4.50 [0.60–91.7], P value < 0.001. In the case group, 57 hypermethylated and 43 normo-methylated among RPL patients vs. 40 hypermethylated and 60 normo-methylated among controls, P< 0.005. Frequency of T allele in C677T MTHFR gene among RPL patients was 29% vs. 23% among the control group; C allele vs. T allele: odds ratio (OR) = 1.367 (95% confidence interval (CI) 0.725–2.581). Conclusion Findings suggested a significant association between hypermethylation of the MTHFR promoter region in RPL patients compared to healthy fertile women.

Abstract Background Around 25% of the world population was affected by the metabolic-related fatty liver disorder. Hepatic steatosis is frequently observed in conjunction with hypertension, obesity comorbidities, and diabetes. We evaluate the hepatic steatosis frequency found in chest CT exams of COVID-19-positive cases compared to non-infected controls and evaluate the related increased prevalence and severity of COVID. Results Our research includes 355 subjects, 158 with positive PCR for COVID-19 (case group) and 197 with negative PCR and negative CT chest (control group). The mean age in the positive group was 50.6 ± 16 years, and in the control, it was 41.3 ± 16 years (p < 0.001). Our study consists of 321 men (90.5%) and 34 women (9.5%). The number of males in both cases and control groups was greater. In the case group, 93% men vs. 6.9% women, while in controls, 88.3% men vs.11.6% women, p < 0.001. CT revealed normal results in 55.5% of individuals (i.e., CORADs 1) and abnormal findings in 45.5% of participants (i.e., CORADs 2–5). In abnormal scan, CO-RADs 2 was 13.92%, while CO-RADs 3–4 were 20.89% of cases. CO-RADs 5 comprised 65.19% of all cases. Approximately 42.6% of cases had severe disease (CT score ≥ 20), all of them were CO-RADs 5. The PCR-positive class had a greater prevalence of hepatic steatosis than controls (28.5% vs.12.2%, p < 0.001). CO-RADs 2 represented 11.1%, CO-RADs 3–4 represented 15.6%, and CO-RADs 5 represented 73.3% in the hepatic steatosis cases. The mean hepatic attenuation value in the case group was 46.79 ± 12.68 and in the control group 53.34 ± 10.28 (p < 0.001). When comparing patients with a higher severity score (CT score ≥ 20) to those with non-severe pneumonia, it was discovered that hepatic steatosis is more prevalent (73.2% vs. 26.8%). Conclusions Steatosis was shown to be substantially more prevalent in COVID-19-positive individuals. There is a relation among metabolic syndrome, steatosis of the liver, and obesity, as well as the COVID-19 severity.

Abstract Objectives This study was designed to evaluate the safety and effectiveness of a two-hand technique combining harmonic scalpel (HS) and laparoscopic Peng’s multifunction operative dissector (LPMOD) in patients who underwent laparoscopic hemihepatectomy (LHH). Methods We designed and conducted a case-control study nested in a prospectively collected laparoscopic liver surgery database. Patients who underwent LHH for liver parenchyma transection using HS + LPMOD were defined as cases (n = 98) and LPMOD only as controls (n = 47) from January 2016 to May 2018. Propensity score matching (1:1) between the case and control groups was used in the analyses. Results The case group had significantly less intraoperative blood loss in milliliters (169.4 ± 133.5 vs. 221.5 ± 176.3, P = 0.03) and shorter operative time in minutes (210.5 ± 56.1 vs. 265.7 ± 67.1, P = 0.02) comparing to the control group. The conversion to laparotomy, postoperative hospital stay, resection margin, the mean peak level of postoperative liver function parameters, bile leakage rate, and others were comparable between the two groups. There was no perioperative mortality. Conclusions We demonstrated that the two-handed technique combing HS and LPMOD in LHH is safe and effective which is associated with shorter operative time and less intraoperative blood loss compared with LPMOD alone. The technique facilitates laparoscopic liver resection and is recommended for use.

Introduction: Hydatidosis is a global disease and one of the most dangerous zoonotic diseases which is found in areas where humans, dogs, and herbivores are in close contact with each other. Methods: In this study, a total of 64 rats were divided into control and case groups, and then 3000 protoscolices were injected into the peritoneal cavity. After 2 months, rats in the case group were given triclabendazole + levamisole at a dose of 6 mg + 4.41 mg/mL orally for 60 days, respectively. Then, after 6 months of infection, the rats of the control and case groups were killed by anesthesia and then an autopsy was performed and the viscera were carefully examined for hydatid cyst infection. Results: The results showed that in the control group, 3 cysts were observed in the liver, 10 in the kidney, and 88 in the lung. The mean number of hydatid cysts in this group was determined to be 33.6. In the case group, 2 cysts were observed in the liver, 6 in the kidney, and 64 in the lungs. The mean number of hydatid cysts in the viscera was 24 in the case group. Conclusions: Statistical analysis of the results obtained from the case and control groups showed that the therapeutic efficacy of triclabendazole + levamisole was 31%, which is not enough to treat cases of hydatid cyst.

Objectives: We investigated the existence of any connection between smoking and sublingual varices (SLV) in the older population. Methods: This case-control study was conducted in 2019 on adults > 65 years old at Kahrizak Charity Nursing Home, Alborz, Iran. We conducted clinical examination and inspection of 222 elderly patients. Both the case group and control group contained the same number of patients (n = 111). SLV were classified as grade 0 (few or none visible) and grade 1 (moderate or severe). The case group included patients with SLV and the control group consisted of those older adults without SLV and who were matched with the case group based on age, gender, blood pressure, denture wearing, and varicose veins in their legs. Cigarette smoking habits were investigated in both groups. Smokers were considered those who smoked at least one cigarette per day for more than six months. Chi-square and odds ratio (OR) were used to statistically analyze the exposure of participants to smoking in both groups. Results: Among 222 participants, 21.6% and 5.4% were smokers in the case and control groups, respectively. The results of our data analysis revealed that SLV were significantly associated with smoking (p < 0.001, OR = 4). Conclusions: Elderly patients with SLV are more likely to be cigarette smokers. Therefore, cigarette smoking cessation programs are recommended for older adults in society.

Abstract Background and purpose: Alcohol-induced osteonecrosis of the femoral head (ONFH) is a complex and heterogeneous disease. Genetic factors and epigenetic modifications are one of the pathogenesis of the disease. However, the influence of epigenetic factors on the disease has not been systematically studied. Our research aims to determine the methylation changes of alcohol-induced ONFH.Methods：An analytical cross-sectional study of a Chinese male population (50 lung cancer patients and 50 controls). The EpiTYPER of the Sequenom MassARRAY platform was used to detect the DNA methylation status of 132 Cytosine-phosphate-Guanine (CpG) sites in the OPG/RANKL/RANK gene promoter region.Results: In the whole study group，Chi-square test was used to analyze the methylation rate between the two groups, and six CpG sites were found to be different, among which OPG1_CpG_2, OPG3_CpG_4, RANK1_CpG_6, RANK3_CpG_10, RANKL2_CpG_21, and RANKL2_CpG_46 in the case group were higher than those in the control group, while OPG4_CpG_2 was lower than that in the control group. Our results showed that 146 CpG sites were measured, of which 32 were undetectable, and of the remaining 114 methylation sites, methylation levels were different in 23 CpG sites in patients with alcohol-induced ONFH compared to healthy controls. Receiver operator characteristic (ROC) curve analysis demonstrated the methylation levels of OPG/RANKL/RANK could efficiently predict the existence of alcohol-induced ONFH.Conclusion: Our study of Chinese men suggests that several CpG sites in the OPG/RANKL/RANK gene in peripheral blood leukocytes of patients with alcohol-induced ONFH are in abnormal methylation state(hypermethylation tended to be more frequent).

Abstract Background The goal of our study is to investigate whether the methylation levels of AHCY and CBS promoters are related to the risk of cerebral infarction by detecting the methylation level of AHCY and CBS genes. Methods We extracted peripheral venous blood from 152 patients with cerebral infarction and 152 gender- and age-matched healthy controls, and determined methylation levels of AHCY and CBS promoters using quantitative methylation-specific polymerase chain reaction. We used the percentage of methylation reference (PMR) to indicate gene methylation level. Results We compared the promoter methylation levels of two genes (AHCY and CBS) in peripheral blood DNA between the cerebral infarction case group and the control group. Our study showed no significant difference in AHCY promoter methylation between case and control. Subgroup analysis by gender showed that the methylation level of AHCY in males in the case group was lower than that in the control group, but the difference was not statistically significant in females. In a subgroup analysis by age, there was no significant difference in the AHCY methylation level between the case and control in the young group (≤44 years old). However, the level of AHCY gene methylation in the middle-aged group (45–59 years old) was significantly higher and the aged group (≥60 years old) was significantly lower than that in the control groups. However, CBS promoter methylation levels were significantly lower in the case group than in the control group (median PMR: 70.20% vs 104.10%, P = 3.71E-10). In addition, the CBS methylation levels of males and females in the case group were significantly lower than those in the control group (male: 64.33% vs 105%, P = 2.667E-08; female: 78.05% vs 102.8%, P = 0.003). We also found that the CBS levels in the young (23–44), middle-aged (45–59), and older (60–90) groups were significantly lower than those in the control group (young group: 69.97% vs 114.71%; P = 0.015; middle-aged group: 56.04% vs 91.71%; P = 6.744E-06; older group: 81.6% vs 119.35%; P = 2.644E-04). Our ROC curve analysis of CBS hypomethylation showed an area under the curve of 0.713, a sensitivity of 67.4%, and a specificity of 74.0%. Conclusion Our study suggests that hypomethylation of the CBS promoter may be closely related to the risk of cerebral infarction and may be used as a non-invasive diagnostic biomarker for cerebral infarction.

Background: There are several risks to health associated with pesticide use. The use of Personal Protective Equipment (PPE) can minimize pesticide exposure to farmers. The aim of this study was to determine the basic characteristics of farmers, blood parameters (complete blood count, cholinesterase, and creatinine), patterns of pesticide use, and the use of PPE. Methods: This research was a cross-sectional study, with total sampling method. The data were taken from all farmers in Kulonprogo, Yogyakarta, Indonesia. Case group was organophosphate sprayers that have sprayed organophosphate for more than 1 year. Results: In case of group, there were 36 farmers (31 male and 5 female), while in control group, there were 11 persons (4 male and 7 female). The mean blood cholinesterase level in the exposed group was 7.8 ± 2.01Ku/L and in the control group 8.7± 1.56 Ku/L. The mean of exposed group blood urea nitrogen: 12.08±3.88 mmol/L and control Group: 11.4±3.11 mmol/L. The mean of blood creatinine was within normal limits (case group: 0.9 ± 0.17mg/dl and control group: 0.7 ± 0.19 mg/dl), but there were significant differences between them (p : 0.015). Conclusions: The results of a complete blood count, cholinesterase, and renal function in the organophosphate sprayers In Kulonprogro were within normal limits. There was an increase of creatinine levels on exposed group significantly, although still within normal limit. They have sufficient rest period for farmers (1 month) in every planting season. It is necessary to educate farmers about the importance of using PPE and management of acute pesticide poisoning.
