PC emerges as a good candidate for sPE diagnosis, since it is a simple and habitually done method, with lower cost and greater accessibility in the clinical laboratory. Further studies evaluating sequential PC and platelet indices throughout pregnancy are necessary to clarify the role of platelet parameters in PE development and severity.

Preeclampsia (PE) is a multifactorial pregnancy-specific syndrome which represents one of the leading causes of maternal mortality worldwide. Inherited thrombophilia have been investigated as risk factor for the development of PE and it is currently known that ABO blood group may impact haemostatic balance, having the non-O blood groups (A, B or AB) subjects increased risk for thrombus formation, as compared to those of group O. We performed a systematic review of the literature for published studies investigating whether ABO blood groups could influence PE developing. A sensitive search of four databases identified 45 unique titles. The retrieved papers were assessed independently by authors and a rigorous process of selection and data extract was conduct. Methodological quality of the included studies was also evaluated. Two studies met eligibility criteria. As a main finding of our systematic review, an association between the AB blood group and the occurrence of PE was detected based on two original studies. Considering the role of ABO blood groups on the hemostatic process and thrombus formation, special attention should be given to pregnant patients carrying the AB blood group in order to prevent the syndrome and improve prognosis.

Colorectal cancer (CRC) corresponds to the third most prevalent type of cancer. Its origins can either be sporadic or inherited, being Lynch syndrome the most common form of hereditary CRC. The activation of BRAF oncogene, inactivation of mismatch repair genes by methylation of CpG islands, and microsatellite instability (MSI) have been reported to be involved in CRC development. The goal of the study was to characterize CRC tumors using clinical and molecular criteria through association and cluster analysis. Amsterdam II and Bethesda guidelines and molecular variables were analyzed in 77 patients from Brazil. The replication error (RER) status, based in microsatellite instability, showed association with metachronous tumor, MLH1 gene methylation and inverse association with left-sided and synchronous tumors. The PMS2 gene was considered the best predictor for differentiating levels of methylation and the mononucleotide were considered the best markers to evaluate RER status. The cluster 1 was characterized of individuals over 60 years of age, female, right-sided tumor, high microsatellite instability, and metachronous or synchronous tumors. The individuals in cluster 2 were younger than 45 years of age, male and showed left sided or rectum tumors, and microsatellite stability. Even though it was not observed a significant association, a higher number of individuals with family history of cancer and tumors without promoter methylation were found in cluster 2. The V600E mutation did not show association with clinical or molecular characteristics. Evaluation of MSI and methylation of MLH1 and PMS2 genes should be considered in order to assist with clinical diagnosis.

Regardless of the mechanisms related to aspirin non-responsiveness, most patients enrolled in the present study also presented a reduced or minimal response to low-dose aspirin therapy, thereby indicating a clear variability related to aspirin effectiveness. Moreover, BMI appears to be independently associated to the reduction of urinary 11-dhTXB₂ concentrations in type 2 diabetic patients taking aspirin.

Obesity, defined as an excess in body fat, is a multifactorial disease involving both genetic and environmental risk factors. Early diagnosis and interventions during critical periods of development of obesity-childhood and adolescence-have been recommended, aiming at preventing unfavorable outcomes at a later age. This cross-sectional study sought to characterize the lipid profile, glucose, adiponectin, leptin and ghrelin in schoolchildren between six and nine years of age with overweight and obesity in the city of Ouro Preto (MG). The data was analyzed with the Shapiro Wilk normality test, groups comparisons were made with either a parametric (T test) or a nonparametric (Mann Whitney) test, adopting confidence intervals of 95% and a significance level of ≤ 0.05. The average age of the school population was 7.8 ± 1.1 years, with a prevalence of 8.9% of overweight and 3% of obesity. Hypercholesterolemia was found in 5.5%, HDL was abnormal in 98.7%, LDL levels were borderline in 32.4% and altered glucose levels were present in 46.6% of the children. In stratified analysis by gender, higher values of leptin in girls (p = 0.032) and ghrelin in boys (p = 0.033) were found, with no difference for the other variables. The results show that overweight/obesity among schoolchildren should be considered a significant health problem in this population, highlighting the importance of implementing early intervention programs. Uncovering the precursors of childhood obesity could lead to interventions so as to prevent or mitigate its consequences in youth and adulthood.
