Is there any relationship between adverse pregnancy outcome and first trimester nuchal translucency measurements in normal karyotype fetuses?

Aim: This study aims to research whether there is a relationship between first trimester nuchal translucency (NT) measurements and pregnancy complications such as gestational diabetes mellitus (GDM), gestational hypertension (GHT), intrauterine growth restriction (IUGR) and oligohydramnios.

Method: This study included 225 singleton pregnancies attending Canakkale Onsekiz Mart University Obstetrics and Gynecology clinic for all monitoring and examinations, and gave birth at our clinic between January 2011 and December 2012. Data sources were clinical records and the hospital's automation system, and the study was planned as retrospective cohort. NT measurement was made between 10 weeks 3 days and 13 weeks 6 days gestation. For data analysis, the chi-square, Mann–Whitney U test and Spearman correlation were used.

Results: Of pregnancies, in the study, 5 (2.2%) developed GDM, 6 (2.6%) developed GHT, 2 (0.89%) developed IUGR and 10 (4.4%) developed oligohydramnios. There was no correlation identified between NT measurements and development of GDM, GHT, IUGR and oligohydramnios.

Conclusion: There was no relationship found between first trimester NT measurements and complications that could develop in pregnancy. For the first time in the literature, NT and oligohydramnios were studied and no relationship was observed.     

The utility of cervical elastosonography in prediction of cervical insufficiency: cervical elastosonography and cervical insufficiency

Objective: To evaluate the utility of cervical elastosonography (ES) in prediction of cervical insufficiency (CI).

Methods: A total of 40 women, of which 20 who had previously received the diagnosis of CI and 20 healty women were included in the study. None of the women were pregnant. All subjects underwent sonographic evaluation including cervical length measurement and ES of uterine cervix. Adjacent muscular tissue was the reference point for elastosonography evaluation. Tissue strain ratio values were obtained from all the patients.

Results: The area around the internal cervical os of the group with CI was found to be significantly softer as compared to the control group (higher SR rate, p?<?0.05). Furthermore, the outer parts of the cervix (sites A and D) were also found harder in the group that had CI (lower SR rate, p?<?0.05).

Conclusions: According to our knowledge, this is preliminary study to evaluate the predictive value of cervical ES in CI and we concluded that ES can be used as reliable method to determine CI but it is necessary to be studied in different cohort groups.     

Effect of dopamine infusion on thyroid hormone tests and prolactin levels in very low birth weight infants

Objective: To evaluate the effect of dopamine on thyroid hormone tests and prolactin (PRL) and to assess requirement for L-thyroxin (LT4).

Methods: The infants (n?=?102) were divided into three groups (Group 1; received no dopamine, Group 2 received ≤25?mg/kg cumulative dose and Group 3; received >25?mg/kg cumulative dose). Blood samples were taken at 6–8 days (timepoint 1), 13–15 days (timepoint 2), and 4–6 weeks of life (timepoint 3).

Results: Respiratory distress syndrome was higher in group 2 and 3. Patnet ductus arteriosus was higher in group 3 than in groups 1 and 2. Duration and cumulative dose in group 3 were higher than group 2. There was no difference between thyroid hormones that were taken after stopping infusion at timepoint 3 among all groups. No therapy with LT4 was needed. PRL levels were higher at timepoint 1 in group 1 than compared to group 2 and 3 (p?p?>?0.05). This difference was disappeared at following timepoints.

Conclusions: The release of TSH, FT3, FT4 and PRL were not inhibited and prophylactic thyroid hormone treatment was not required in VLBW infants receiving dopamine infusions.     

Outcomes for haematological cancer patients admitted to an intensive care unit in a university hospital

Background

Haematological cancer (HC) patients are increasingly requiring intensive care (ICUs). The aim of this study was to investigate the outcome of HC patients in our ICU and evaluate 5 days-full support as a breakpoint for patients’ re-assessment for support.

Compliance With Dyslipidemia Guidelines in Daily Practice: How Effective Is Cardiovascular Risk Prevention?

Purpose

Cardiovascular disease (CVD) due to atherosclerosis is the leading cause of early mortality and morbidity. The current European guidelines on CVD prevention in clinical practice recommend the use of the Systematic Coronary Risk Estimation (SCORE) system. The current American Heart Association guidelines recommend the use of the new pooled cohort risk assessment equations to estimate the 10-year atherosclerotic CVD risk. The purpose of this article was to investigate the compliance of dyslipidemia guidelines in daily practice in patients with dyslipidemia or who have risk factors for CVD.

Fabrication of novel electrochemical sensors based on modification with different polymorphs of MnO2 nanoparticles. Application to furosemide analysis in pharmaceutical and urine samples

A novel MnO₂ nanoparticles/chitosan-modified pencil graphite electrode (MnO₂ NPs/CS/PGE) was constructed using two different MnO₂ polymorphs (γ-MnO₂ and ε-MnO₂ nanoparticles). X-ray single phases of these two polymorphs were obtained by the comproportionation reaction between MnCl₂ and KMnO₄ (molar ratio of 5 : 1). The temperature of this reaction is the key factor governing the formation of the two polymorphs. Their structures were confirmed by powder X-ray diffraction (XRD), Fourier transform infrared (FTIR) and energy dispersive X-ray (EDX) analysis. Scanning electron microscopy (SEM) was employed to investigate the morphological shape of MnO₂ NPs and the surface of the bare and modified electrodes. Moreover, cyclic voltammetry and electrochemical impedance spectroscopy (EIS) were used for surface analysis of the modified electrodes. Compared to bare PGE, MnO₂ NPs/CS/PGE shows higher effective surface area and excellent electrocatalytic activity towards the oxidation of the standard K₃[Fe(CN)₆]. The influence of different suspending solvents on the electrocatalytic activity of MnO₂ was studied in detail. It was found that tetrahydrofuran (THF) is the optimum suspending solvent regarding the peak current signal and electrode kinetics. The results reveal that the modified γ-MnO₂/CS/PGE is the most sensitive one compared to the other modified electrodes under investigation. The modified γ-MnO₂/CS/PGE was applied for selective and sensitive determination of FUR. Under the optimized experimental conditions, γ-MnO₂/CS/PGE provides a linear response over the concentration range of 0.05 to 4.20 μmol L⁻¹ FUR with a low limit of detection, which was found to be 4.44 nmol L⁻¹ (1.47 ng mL⁻¹) for the 1^st peak and 3.88 nmol L⁻¹ (1.28 ng mL⁻¹) for the 2^nd one. The fabricated sensor exhibits a good reproducibility and selectivity and was applied successfully for the determination of FUR in its dosage forms and in spiked urine samples with good accuracy and precision.
