S.S. and M.D.J. have received research support from Takeda to investigate the effects of pioglitazone on intramuscular triglyceride metabolism.

Objective:To analyze maternal deaths in Turkey due to hypertensive disorders.Material and Methods:In this retrospective study 812 maternal deaths were analyzed. Maternal demographic features, presence of antenatal care, medical and obstetric history, mode of delivery, and use emergency antihypertensive therapy were recorded. The delay model for each case was investigated.Results:Hypertensive disorders accounted for 15.5% (n=126) out of all maternal mortality. They were the third most frequent cause among all causes and the 2nd among direct causes of maternal deaths. Sixty-one (48.4%) cases were in severe preeclampsia or pre-existing hypertensive disorder with increased/superimposed proteinuria, 30.1% were in eclampsia, 9.5% cases were diagnosed as hemolysis, elevated liver enzymes, low platelet count syndrome, and 11.1% in pre-existing hypertension complicating pregnancy, childbirth, and puerperium without increased or superimposed proteinuria. The median age was 32 years, 37.3% women were ≥35 years. All deaths except for 2 cases occurred during the postpartum period. Twenty-three percent of deaths occurred in the first 48 hours postpartum, and 51.6% between 8-42 days. Intracranial hemorrhage was the major final cause of death with a rate of 41.3%. With the exception of fifteen patients with intracranial hemorrhage, emergency antihypertensive agents were not implemented in optimal dose and/or duration. A first and/or third delay was identified in 36.5% of cases.Conclusion:Approximately one third of maternal death due to hypertensive disorders could be prevented. The importance of acute antihypertensive treatment should be emphasized because of most frequent cause of death was intracranial hemorrhage.

Background. Subclinical hypothyroidism (SH) predominantly affects women. The necessity of treatment in SH is controversial. Objective. We aimed to investigate the response of diastolic dysfunction to thyroid hormone replacement therapy (THRT) in women. Methods and Results. Twenty-two female subjects with SH and 20 euthyroid female controls were enrolled. Baseline and follow-up biochemical, hormonal, and echocardiographic evaluations were performed. Repeat echocardiograms were performed three months after the achievement of a euthyroid status with THRT. Mean baseline myocardial performance index (MPI) was 0.27 ± 0.08 in the SH group, and 0.22 ± 0.06 in the control group (P = 0.03). MPI did not change significantly after THRT. Pulsed-wave Doppler findings were not different among the groups. However, tissue Doppler-derived mitral annular E' velocities were significantly lower in the SH group. A moderate but significant improvement was observed in E' velocities after THRT (13.2 ± 3.87 versus 14.53 ± 2.75, P = 0.04). We also observed left ventricular concentric remodeling in SH patients which was reversible with THRT. Conclusions. Tissue Doppler echocardiography may be a useful tool for monitoring the response of diastolic dysfunction to thyroid hormone replacement therapy in patients with SH. Our findings suggest that THRT may reverse diastolic dysfunction in women with SH.

The aim of the present study was to evaluate plasma total homocysteine (Hcys) and serum fibrinogen concentrations in subclinical hypothyroid (SH) and overt hypothyroid patients before and after L-thyroxine (LT4) replacement and to compare them in euthyroid subjects. Fifteen SH and 20 hypothyroid premenopausal women were recruited in the study. We measured fasting plasma levels of Hcys and serum levels of free thyroxine (fT4), free triiodothyronine (fT3), thyrotropin (TSH), folate, vitamin B12, fibrinogen, renal functions, and lipid profiles in patients with SH and overt hypothyroid patients before and after LT4 treatment. Eleven healthy women were included in the study as a control group. Pretreatment Hcys levels were similar in SH and control subjects, whereas mean fibrinogen level of SH patients was higher than that of control subjects (p<0.05). Baseline Hcys (p<0.01) and fibrinogen (p<0.001) levels of the overt hypothyroid patients were significantly higher than those of the healthy subjects, and the pretreatment Hcys levels decreased with LT4 treatment (p<0.001). In conclusion, our data support that SH is not associated with hyperhomocysteinemia and Hcys does not appear to contribute to the increased risk for atherosclerotic disease in patients with SH.

Clinical observations have indicated the frequent development of thrombotic complications during diabetic ketoacidosis (DKA). This study aimed to examine whether haemostatic changes that could lead to a thrombotic tendency occur during ketoacidosis. Plasma levels of in vivo haemostatic markers reflecting activation degrees of the coagulation system, fibrinolytic system, platelets and endothelium were assayed in 34 patients with DKA, both at diagnosis and 1 week after recovery. We found coagulation system and platelet activation and endothelial injury/activation in the patients at diagnosis of DKA. Although significant improvements were observed after recovery, only platelet activity was completely normalized. Fibrinolytic activity was also increased, both at diagnosis and after recovery, compared to the control group. However, although coagulation activity was prominently increased at diagnosis compared to the recovery period, there was no change in fibrinolytic activity in the same periods; on the contrary, the fibrinolytic capacity of the endothelium was diminished at diagnosis of DKA compared to the recovery period, suggesting the presence of relative hypofibrinolysis during DKA. Indications for a role of hyperglycaemia in the emergence of haemostatic disturbances during DKA were observed.
