ACTA ENDOCRINOLOGICA (BUC)

OBJECTIVES: This study was carried out on 1290 patients, whose choroids plexus and pineal gland were examined on computed tomography. Aim: To check the correspondence between the choroid plexuses and the pineal gland calcifications along age groups and sex; and the connections between these calcifications and associated pathology.\r\nMATERIALS AND METHODS: The study group consisted of patients of both sexes, within six age intervals.\r\nRESULTS: In order to classify the calcification variants, eight types of combinations were ordered and can be seen in CT: two refer to extreme variants: totally uncalcified (type 1) and totally calcified (type 8); bilateral, symmetrical variants (types 4 and 5); the other four types include the asymmetrical calcifications (2, 3, 6 and 7). After the anthropological study the results demonstrate that there are significant differences between calcification of the choroids plexus and those of the pineal gland with the two sexes, on age groups and pathological ground. For type 1-totally uncalcified the maximum frequency is around 70% with ages under 19. For type 8 - totally calcified, bilateral, the maximum frequency is around 50% with age groups 48-59 and 60-71. For type 4 - calcification only of choroid plexus, one finds a continuous increase from about 10% at the first age group to about 25% at the last group, while for type 5- calcification only of the pineal gland the frequency is 10%−20%. We started from the hypothesis that the presence of these calcifications is physiological, and has an active adaptative metabolic part depending on many factors, among which the individual constitutional ground is also present.\r\nCONCLUSIONS: The age is not the main cause of the calcification types, but a process of adaptative-reactive variability of interface type, playing an integrating mediating part.

Aims. To investigate the historical changes in survival with diabetes in patients treated with insulin from diagnosis.\r\nMethods. We analyzed 2811 deaths, 51.5% males, registered at ?I. Pavel? Bucharest Diabetes Centre, aged 40-64 years and deceased between 1943 and 2009. We split the analysis in three time periods according to year of death: 1943-1965,\r\n1966-1988 and 1989-2009.\r\nResults. The mean age at diabetes onset was 51.4?6.8 years, with mean disease duration at death of 17.7?11.6 years\r\nand mean age at death of 69.1?11.2 years. The mean survival after diabetes onset was 13.9?9.8 years in 1943-1965, and rose to 17.3?9.6 years (p<0.001) in 1989-2009. There was a significant increase for coronary heart diseases and cancer and a significant decrease for infections and endstage\r\nrenal disease as causes of death.\r\nConclusions. We found no significant changes in age at onset, which combined with an increase in survival with diabetes lead to a significant increase in age at death.\r\nMajor historical events have a strong impact over survival after the onset of diabetes.

The discovery of the cannabinoid receptors CB1 and CB2 in 1990 and 1993, respectively, as well as of the two main endocannabinoids, anandamide in 1992 and 2-arachidonylglycerol in 1995, was an important step in identifying the strongest homeostatic system in the human body, namely the endocannabinoid system. Ever since, research has highlighted the crucial part played by this system in all the reproduction stages: folliculogenesis, spermatogenesis, oogenesis, fecundation, transport of the egg through the fallopian tubes, blastocyte implantation and pregnancy progression, as well as its implications in the physiopathology of the reproductive system: in endometriosis, ectopic pregnancy, miscarriage, preeclampsia, endometrial cancer, polycystic ovary syndrome, ovarian cancer. A special attention must be paid to the phytocannabinoids, natural components originating especially from the Cannabis plant inflorescences, whose medical effects are wellestablished nowadays with also acting on the receptors of the endocannabinoid system. The most recent research mainly focuses on the reproductive dysfunctions and disorders of the reproductive tissues, respectively, through its action upon the endocannabinoid system. Medical cannabis is nowadays legalized in more and more countries all over the world. At the same time, recreational cannabis remains one of the most consumed drugs (in Romania the most consumed one by young adults). Therefore, it is mandatory for specialists in obstetrics and gynecology, endocrinology, public health, hygiene or for general practitioners, to permanently update their information on this subject.

Atherosclerotic Cardiovascular Diseases are the leading cause of death worldwide. Aim. To estimate the prevalence of cardiovascular risk (CVR) categories in the adult population (aged 40-79 years) of Romania. Design. The present study was part of the epidemiological, cross-sectional PREDATORR study (PREvalence of DiAbeTes mellitus, prediabetes, overweight, Obesity, dyslipidemia, hyperuricemia and chronic kidney disease in Romania). Subjects and Methods. Exclusion criteria: age <40/ or>79 years old and diagnosis of ischemic vascular disease. The CVR was evaluated using charts developed by the World Health Organization/ International Society of Hypertension (WHO/ISH) available for Europe B (epidemiological subregion where Romania was included). The CVR was divided into 5 categories: <10%, 10-20%, 20-30%, 30-40%, > 40%. Results. A total of 1631 subjects (57.0±10.7 years, 45.1% males) were included in the present study. The age and sex-adjusted prevalence of CVR >40% was 2.9% (95%CI 2.8-3.1%), CVR 30-40% was 1.85% (95%CI 1.8-1.9%), CVR 20-30% was 5.8% (95%CI 5.6- 6.0%) and 13.0% (95%CI 12.8-13.3%) of the adult Romanian population has a 10-20% CVR, these CVR categories being more frequent in male and older age. Diabetes, overweight/ obesity and smoking were associated with high CVR categories. Conclusion. Romania is one of the countries with high CVR, requiring CVD prevention measures.

The pathogenesis of type 1 diabetes became a history longer and longer. There are 40 years since the immunogenetic theory of type 1 diabetes has been launched. Near this anniversary a challenge of this theory was recently published. We give here our interpretation of primary cause of type 1 diabetes which must be connected with the pathogenesis of other phenotypes of diabetes which has a main similar mechanism: the β-cell dysfunction.

Aims. To investigate the effect of sulphonylurea (SU) treatment on all-cause and cardiovascular mortality as compared with metformin (MET), when used in combination with insulin (INS) in type 2 diabetes. Methods. All type 2 diabetes patients aged ≥40 years were included at their first prescription of INS+MET or INS+SU, during 2001-2008. They were considered at risk until death or December 31st, 2011. Mortality rates were calculated per 1000 person-years. Crude and adjusted rate ratios (RR) were calculated using time dependent analysis with INS+MET as reference. Results. There were 7122 patients (60.8% women) included in the analysis, with a mean age at baseline of 62.0±9.9 years. During the 11 years of study, patients on INS+MET contributed 13620 person-years and 330 deaths (mortality rate 24, CI95% 22-27), while those on INS+SU contributed 8720 person-years and 393 deaths (mortality rate 45, CI95% 41-50). Adjusted all-cause mortality RR were: SU 1.6 (CI95% 1.21-2.11, p<0.001), glimepiride 1.18 (CI95% 0.73-1.91, p=0.51), gliclazide 1.78 (CI95% 1.07-2.95, p=0.024), glibenclamide 1.66 (CI95% 0.71-3.88, p=0.23), glipizide 1.24 (CI95% 0.68-2.27, p=0.49), and gliquidonum 2.32 (CI95% 1.54-3.50, p=0.001). Conclusions. When combined with insulin as dual therapy, patients treated with SU were at increased mortality risk as compared with insulin + MET.

Diabetes Mellitus is a huge syndrome which can be detected from the first day of life until the last year of life of a centenarian. In the current classification of diabetes among the so-called “idiopathic phenotypes”, apart Type 1 Diabetes (T1D) and Type 2 Diabetes (T2D) has been included provisionally term “Latent Autoimmune Diabetes in Adults” (LADA). This has unclear characterization regarding the age at onset, the presence of anti-β-cell antibodies and the level of insulin secretory function, in conformity with C-peptide levels. According to several recent publications, there are no specific biochemical or genetic markers for Latent Autoimmune Diabetes in Adults (LADA), but only a gradual transition from T1D to T2D. In addition, the word “latent” in the construction of “LADA” term is inaccurate because in this phenotype nothing is latent: both the autoimmunity and diabetes are present and are even parts of the diagnosis. So that, the best term should be what in reality this subphenotype is: an Intermediary Diabetes Mellitus (IDM). Some recent genetic data strongly support this designation.
