    ABSTRACT: Gestational diabetes mellitus may precede development of Type 2 diabetes and may be related to cardiovascular disease. Pulse wave velocity measurement is the gold-standard method to evaluate arterial stiffness, a preclinical cardiovascular risk marker. However, the relationship between aortic stiffness and gestational diabetes is unclear. The aim of this study was to evaluate aortic pulse wave velocity in women with gestational diabetes in comparison with a matched control group of healthy pregnant women. This case-control study included 24 women with gestational diabetes and 27 matched control subjects. Clinical, demographic and laboratory variables were obtained and aortic pulse wave velocity were measured. Both groups had similar age, gestational age, BMI, ethnicity, smoking status and blood pressure levels. Women with gestational diabetes had aortic pulse wave velocity comparable with control subjects: 7.2 ± 0.9 vs. 7.3 ± 1.2 m/s (P = 0.79). When categorized according to the median value of pulse wave velocity (7.3 m/s), age (P < 0.001), diastolic blood pressure (P = 0.03) and heart rate (P = 0.02) were associated with increased arterial stiffness. In the group with gestational diabetes, there was a non-significant trend towards higher 1-h postprandial glycaemia in patients with higher (above the median) pulse wave velocity (6.5 ± 0.8 vs. 7.1 ± 1.3 mmol/l, P = 0.22) and a lower prevalence of patients with good glycaemic control (38.5 vs. 72.7%, P = 0.09). Although gestational diabetes may be a risk factor for development of cardiovascular disease, women with gestational diabetes do not have higher aortic stiffness than healthy pregnant women. Time of exposure to hyperglycaemia may have been insufficient to increase central arterial stiffness in women with gestational diabetes.

    ABSTRACT: It has been suggested that type 1 (T1D) and type 2 diabetes (T2D) might share some susceptibility risk factors. A higher prevalence of T2D has been reported in families of Caucasian T1D children than in the general population, although data in adults and multiethnic groups is still lacking. Our goal was to compare the prevalence of T2D family history between adults with T1D from a multiethnic population and a non-diabetic control group. We performed a cross-sectional analysis of 145 adults with T1D and 141 healthy adults (control group) that included an interview and a review of the medical charts. Groups were matched for age, sex, ethnicity and body mass index (BMI). We found a higher prevalence of not only T1D but also T2D in first-degree relatives of patients than in controls (p<0.001 and p=0.042, respectively). These differences were not observed for second/third-degree relatives. When subjects were stratified according to their ethnicity, the higher frequency of T2D in FDR of patients than controls became more striking in non-white (p=0.002) and disappeared in white individuals (p=0.85). To conclude, the prevalence of T1D and T2D was higher in first-degree relatives of patients with T1D than of controls. The difference in T2D family history between patients and controls was specially striking among non-whites, which may represent a peculiarity of T1D in this group.

    ABSTRACT: Acute infectious thyroiditis is a rare condition of the thyroid gland, most often arising in children with congenital conditions connecting the thyroid directly to the oropharynx, such as a piriform fistula or thyroglossal duct. We report a case of acute thyroiditis due to septic emboli derived from infective endocarditis.
