BACKGROUND: Although the exact mechanism leading to preeclampsia is not fully understood, abnormal trophoblast invasion contributes to its pathogenesis. Keratins and cadherin are known to play roles in the regulation of trophoblast proliferation. However, studies describing the association between keratins, cadherin, and preeclampsia are limited. AIM: The current study was conducted to investigate the association of these proteins with severe preeclampsia in Sudanese women. METHODS: A case–control study was conducted at Madani Maternity Hospital, Sudan. The cases included women with severe preeclampsia (n = 56) and healthy pregnant women as controls (n = 56). The assessment of keratin and cadherin was performed using immunohistochemical staining. RESULTS: There was no significant difference between the two groups in their mean age or parity. We found no significant differences in the expression of the markers E-cadherin, N-cadherin, or cytokeratin 18 and 19 in the placentas from individuals with preeclampsia versus controls. The number of placentas with severe preeclampsia versus controls expressing the E-cadherin, N-cadherin, cytokeratin 18, and cytokeratin 19 markers was 46 (82.1%) versus 46 (82.1%) (p = 0.988), 54 (96.4%) versus 48 (85.7%) (p = 0.121), 4 (7.1%) versus 0 (0%) (p = 0.126), and 11 (19.6%) versus 11 (19.6%) (p = 0.532), respectively. There was also no significant difference in the intensity of staining of these four markers (Ecadherin, N-cadherin, and cytokeratin 18 and 19) between severe preeclampsia and control placentas. CONCLUSION: Together, these results indicate that in this setting, the expression of E-cadherin, N-cadherin, CK18, and CK19 is not associated with severe preeclampsia.

BackgroundA previous study showed an association between owner-reported exposure to environmental tobacco smoke (ETS) and lymphoma in cats. This study aimed to investigate the association between ETS exposure and gastrointestinal lymphoma in cats, using hair nicotine concentration (HNC) as a biomarker.MethodsThis was a prospective, multi-centre, case–control study. Gastrointestinal lymphoma was diagnosed on cytology or histopathology. Hair samples were obtained from 35 cats with gastrointestinal lymphoma and 32 controls. Nicotine was extracted from hair by sonification in methanol followed by hydrophilic interaction chromatography with mass spectrometry. Non-parametric tests were used.ResultsThe median HNC of the gastrointestinal lymphoma and control groups was not significantly different (0.030 ng/mg and 0.029 ng/mg, respectively, p=0.46). When the HNC of all 67 cats was rank ordered and divided into quartiles, there was no significant difference in the proportion of lymphoma cases or controls within these groups (p=0.63). The percentage of cats with an HNC≥0.1 ng/mg was higher for the lymphoma group (22.9%) than the control group (15.6%) but failed to reach significance (p=0.45).ConclusionA significant association was not identified between HNC (a biomarker for ETS) and gastrointestinal lymphoma in cats; however, an association may exist and further studies are therefore required.

  Obesity has become a global public health problem. It occurs due to a positive energy balance leading to adipose tissue expansion. White adipose tissue was an endocrine organ which secreted resistin. Resistin also produced by immune cells due to low chronic level inflammation might cause higher resistin level in obese people. Polymorphism +62G>A RETN gene was reported has a relationship with low resistin level and A allele as a protective allele. This study aimed to determine genotype and allele frequency distribution concerning resistin level. Another objective aimed to know the correlation between resistin level with body mass index. The design of the research was a case-control study with 122 people (18-40 y.o.), divided equally in the case group (BMI ≥ 27 kg/m2) and control group (BMI 18.5-24.9 kg/m2) without diabetes mellitus. Blood was taken after fasting a minimal 8 hours. Plasma was used to measure the resistin level. DNA genotyping was analyzed using PCR-RFLP. Genotyping result showed three genotypes of RETN gene +62G>A polymorphism (GG, GA, AA). There was no significant difference in genotype and allele frequency distribution related to obesity status (p=0.680; p=1) and resistin level (p=0.537) between case and control group. There was no significant difference in resistin level between case and control group (p=0.770). Resistin level was correlated with BMI in obese group (p= 0.05; r= -0.25). The present study concludes that there is no significant difference in genotype and allele frequency distribution related to obesity status and resistin level. Resistin level has a negative correlation with BMI.

Background: Preeclampsia is one of the most common pregnancy complications, which is one of the major causes of fetal and maternal mortality. Objective: To compare the serum Brain Natriuretic Peptide (BNP) level in patients with severe preeclampsia and normal pregnancy and investigate associated cardiovascular complications. Materials and Methods: This case-control study was performed on 94 women with a singleton pregnancy (severe preeclampsia and normal pregnancy) at Imam Reza Hospital in Mashhad, Iran. The venous blood samples were collected to evaluate the serum BNP level. All patients were subjected to echocardiography performed by a single cardiologist. Results: The mean pro-BNP levels were 480.36 ± 754.52 and 67.46 ± 106.24 pg/dL in the severe preeclampsia and normal pregnancy patients, respectively (p < 0.001). However, adjusted BNP for maternal and gestational age was not different in the two groups (ANCOVA, p = 0.69). Furthermore, the two study groups showed no significant difference in terms of the cardiac parameters, including ejection fraction (EF), left ventricle end-diastolic and -systolic diameters (LVEDD and LVESD, respectively), tricuspid annular plane systolic excursion (TAPSE), and ratio of the early transmitral flow velocity to the early diastolic tissue velocity (E/Em). However, the serum BNP level showed a significant correlation with EF (r = -0.39, p = 0.008), TAPSE (r = -0.47, p = 0.001), and E/Em ratio (r = 0.48, p = 0.001) in patients with severe preeclampsia. Conclusion: It seems that BNP can be used as a predictor for some of the main cardiac functional indices (i.e., E/Em, EF, and TAPSE) in severe preeclampsia patients.

This study had the objective to assess the frequency of Tregs in children newly diagnosed with ITP and ascertain whether an association exists between Tregs and platelet counts, by means of a comparison with healthy controls. This case-control study included 19 patients newly diagnosed with ITP—whose blood samples were collected at four points in time: before any therapy and 1, 3, and 6 months after diagnosis—and 19 healthy controls. Tregs (CD4+ CD25+Foxp3 T cells) were evaluated by flow cytometry. There was a statistically significant difference in platelet count between the case and control groups. There were no significant differences in Treg counts between cases and controls at any point during the course of the study and no difference in Treg counts between the chronic and nonchronic groups and no significant correlation between Tregs and platelet counts in the case and control groups. The findings of this study did not show any statistically significant correlation between Tregs and number of platelets in the case and control groups. Treg cells did not play a role in the regulation of autoimmunity in children with ITP.

Background: Bladder cancer is the second most common cancer of the genitourinary system and the eighth cause of cancer death. In addition to known risk factors such as smoking and urinary stones, trace elements are also effective in causing bladder cancer and other cancers. Objectives: This study was conducted to determine the association between bladder cancer and the carcinogens cadmium and arsenic. Methods: This case-control study was conducted on 40 patients with bladder cancer admitted to Shahid Bahonar Hospital and a control group of 40 healthy individuals in Kerman, Iran, in 2018. The serum levels of arsenic and cadmium were measured by atomic absorptiometry. The paired t-test and chi-square tests were employed to assess the difference between cases and controls groups. An unadjusted and 2 multivariable conditional regression models were separately adjusted on sex, family cancer history, residence, occupation, and smoking and were used to estimate odds ratios (OR) and 95% confidence intervals (95% CI) to assess the association between arsenic and cadmium levels and bladder cancer. The statistical software SPSS version 26 and R software version 3.6.3 were used to perform the statistical analyses. Results: The mean cadmium level was 2.99 ± 1.45 and 2.59 ± 0.46 in the case and control groups, respectively, with no statistically significant difference between the groups (P = 0.100). The mean arsenic level was 2.12 ± 1.04 and 1.43 ± 0.73 in the case and control groups, respectively, demonstrating a statistically significant difference between the groups (P = 0.001). Unadjusted and adjusted conditional logistic regression models indicated significant association between arsenic levels and bladder cancer (unadjusted: odds ratio (OR) (95% CI): 0.66 (0.46 - 0.94), P-value = 0.022; adjusted: OR (95% CI): 0.64 (0.44 - 0.92), P-value = 0.018). Conclusions: Overall, cadmium and arsenic levels are higher in patients with bladder cancer, with a statistically significant difference for arsenic. However, these elements are not interrelated and are not related to other factors.

Background: Mammographic breast density (MBD) is a predictor of breast cancer while bone mineral density (BMD) is a marker of estrogen and calcium level. Aim: The objective of the study is to compare MBD, BMD, estrogen and calcium level between the cancer and control groups. Method: This case-control study was done on 40 women in each control and cancer group. The women had mammography and dual energy x-ray absorptiometry at Kuala Lumpur Hospital. Respondents were chosen using purposive sampling and women who had commenced cancer treatment were excluded from the study. Blood samples were taken to analyze serum estrogen and calcium level of the subjects. Results: The demographic characteristic of the control and cancer patients were similar in age, body mass index and menarche age. The mean of selected variables were compared between groups using independent t test and Mann-Whitney for continuous and categorical data respectively. There was significant difference for estrogen between the groups. Person correlation showed moderate correlation between estrogen level and BMD. Women with scattered fibroglandular breasts and dense breast were the most affected by cancer, multiple logistic regression showed significant difference between the groups for breast density ( P = 0.047) and estrogen level ( P = 0.002). Conclusion: There is significant difference between cancer and control group for MBD and estrogen level.
