Chronic hyperglycemia and intracranial meningiomas.

Meningiomas are among the most common primary tumors of the central nervous system. Previous research into the meningioma histological appearance, genetic markers, transcriptome and epigenetic landscape has revealed that benign meningiomas significantly differ in their glucose metabolism compared to aggressive lesions. However, a correlation between the systemic glucose metabolism and the metabolism of the tumor hasn't yet been found. We hypothesized that chronic levels of glycaemia (approximated with glycated hemoglobin (HbA1c)) are different in patients with aggressive and benign meningiomas. The study encompassed 71 patients with de novo intracranial meningiomas, operated on in three European hospitals, two in Croatia and one in Spain. Our results show that patients with WHO grade 2 meningiomas had significantly higher HbA1c values compared to patients with grade 1 lesions (P = 0.0290). We also found a significant number of patients (19/71; 26.7%) being hyperglycemic, harboring all the risks that such a condition entails. Finally, we found a significant correlation between our patients' age and their preoperative HbA1c levels (P = 0.0008, ρ(rho) = 0.388), suggesting that older meningioma patients are at a higher risk of having their glycaemia severely dysregulated. These findings are especially important considering the current routine and wide-spread use of corticosteroids as anti-edematous treatment. Further research in this area could lead to better understanding of meningiomas and have immediate clinical impact.

Does the BMI of Expectant Mothers Influence the Concentration of C-Reactive Protein in Newborns in the Early Neonatal Period?

Aim: The aim of the study is to determine the effect of body mass index in pregnancy on the CRP concentration in pregnant women and their newborn. The results of the study will serve as a guide for a more valid assessment of slightly elevated concentrations of CRP and a potential new guide for the treatment of newborns with antibiotics. Method: The research is a cohort prospective study of 2 groups of pregnant women and their newborn with respect to the body mass index of the pregnant women prior to delivery. The study included 128 pregnant women and their newborn whose serum was analysed to ascertain CRP concentration. Results: The CRP concentration in pregnant women with an elevated BMI was higher than in the pregnant women with normal BMI during pregnancy. The difference is statistically significant (p<0.001). The CRP concentration taken from the umbilical cord and during the second day of life of the newborn of the pregnant women with an elevated BMI was statistically significantly higher than in the newborn of the pregnant women with normal BMI during pregnancy (p<0.001). A repeated blood test conducted between the third and fifth day of life showed that the concentration of CRP in the newborn of both study groups was within referential values. Conclusion: The study indicates a significant correlation between BMI in pregnancy and CRP concentration in pregnant women and their newborn. The results of this study are a potential milepost in addressing the dilemma of whether to administer antibiotics to newborns with elevated CRP values (<20 mg/L) without aggravating their clinical condition. It may be necessary to simply repeat the laboratory tests of CRP in the blood of the newborn in the first days of life and thus follow its dynamics.

Could nasal septal deformities type 5 and 6 be a predictive factor of the indi- vidual genetic predilection for the onset of an acute coronary syndrome?.

OBJECTIVES: the possible impact of nasal septal deformities (SD) on cardiac pathology has not been well studied, despite growing evidence among data showing that upper air-way obstruction has a negative effect on cardiac function in general and a "deviated nasal septum" being considered one of the most frequent factors responsible for impaired nasal breathing. METHODS: a retrospective, case-control, double-blind study was performed on 249 patients who survived an acute coronary syndrome (ACS) attack. All patients underwent coronary angiography and were divided into coronary angiography positive (123 pts) and coronary angiography negative (126 pts) groups. The quality of nasal breathing was not considered in this study, but morphological aspects of the nasal septum (nasal septal deformities) were observed by anterior native rhinoscopy and endoscopic examination of the nose following the application of superficial anaesthesia. Mladina classification of nasal septal deformities was used. RESULTS: there was a statistically significant difference between coronary angiography negative and positive patients in Mladina type 1 to Mladina type 7 groups (p=0.000, X²=54.605). The incidence of nasal SD types 5 and 6 was higher in the group of ACS patients with the positive coronary angiography, whereas general distribution of the particular types of nasal septal deformities as they appear in the general population was found in the coronary angiography negative group. CONCLUSION: the fact that types 5 and 6 are inherited deformities and not related to trauma against the nose suggests the possible genetic predisposition for the onset of ACS with positive coronary angiography.
