Türkiye’de Tüketici Haklarının Gelişimi Ve Hak Arama Yolu Olarak İnternet

Sensitivity for the protection of consumers increase more and more every day and the subject becomes an agenda in the public opinion. Studies carried out under different names and legal arrangements in the pre-industrial societies, are accelerated by industrialization. The provisions regarding the Consumer Protection entered into the Turkish Legislation by the Constitution of 1982, have taken their last shape in the Act No. 6502 enacted in the year of 2013 and the relevant Regulations. The internet, which is an indispensable element in the globalized world, has become an important platform where the consumers voiced their complaints. The aim of this study is to analyze the complaints most shared over the internet and to examine the regulations made by the Act No. 6502 related to these complaints

Maternal near-miss patients and maternal mortality cases in a Turkish tertiary referral hospital

Objectives: This study aimed to estimate the incidence of maternal near-miss (MNM) morbidity in a tertiary hospital setting in Turkey. Material and methods: In this retrospective study, we concluded 125 MNM patients who delivered between January 2017 and December 2017 and fulfilled the WHO management-based criteria and severe pre-eclamptic and HELLP patients which is the top three highest mortality rates due to pregnancy. Two maternal death cases were also included. The indicators to monitor the quality of obstetric care using MNM patients and maternal deaths were calculated. Demographic characteristics of the patients, the primary diagnoses causing MNM and maternal deaths, clinical and surgical interventions in MNM patients, shock index (SI) value of the patients with obstetric hemorrhage and maternal death cases were evaluated. Results: The MNM ratio was 5.06 patients per 1000 live births. Maternal mortality (MM) ratio was 8.1 maternal deaths per 100 000 live births. SMOR was 5.14 per 1000 live births. The MI was 1.57%, and the MNM/maternal death ratio was 62.4:1. The SI of MNM patients with obstetric hemorrhage was 1.36 ± 0.43, and the SI of the patient who died due to PPH was 1.74. Conclusion: The MNM rates and MM rates in our hospital were higher than high-income countries but were lower than in low- and middle-income countries. Hypertensive disorders and obstetric hemorrhage were the leading conditions related to MNM and MM. However, the MIs for these causes were low, reflecting the good quality of maternal care and well-resourced units. Adopting the MNM concept into the health system and use as an indicator for evaluating maternal health facilities is crucial to prevent MM

The comparison of systemic inflammatory response markers and Doppler ultrasound parameters between pregnancies with intrahepatic cholestasis and control cases

Objective: This study aims to detect a relationship between inflammatory markers, ductus venosus (DV) pulsatility index (PI), middle cerebral artery (MCA) PI, and umbilical artery (UA) systole to diastole ratio (S/D) and PI between pregnancies with intrahepatic cholestasis and control cases. Methods: This prospective study included 82 cases having intrahepatic cholestasis of pregnancy (ICP) and 80 gestational age-matched healthy control cases. The Doppler measurements (DV PI, MCA PI, and UA S/D and PI), inflammatory markers (neutrophil to lymphocyte ratio [NLR], platelet to lymphocyte ratio [PLR], mean platelet volume [MPV], and red blood cell distribution width [RDW]), and fetal and maternal outcomes were compared. Results: Patients with ICP had increased PLR value (p=0.019) and decreased lymphocyte count (p=0.004) compared to control cases. Also, there was a positive correlation between PLR value and the presence of ICP (χ2=5.774, p=0.016). There were no significant differences between ICP and control groups concerning NLR, RDW, MPV, and UA PI values. We found higher UA S/D, and DV PI values and lower MCA PI values in pregnancies with ICP compared to controls (p<0.001, p=0.026, and p=0.003, respectively). Conclusion: In ICP cases, the PLR value was significantly increased than the controls, but the NLR, RDW, MPV, and UA PI values were found to be similar to control cases. The UA S/D, and DV PI values were increased, and MCA PI was significantly decreased in the ICP group compared to healthy pregnancies. However, we could not demonstrate the benefit of Doppler measurements in predicting neonatal outcomes in ICP cases

Maternal serum IL-22 concentrations are significantly upregulated in patients with preterm premature rupture of membranes

Objectives: This study aimed to compare the serum IL-22 levels between preterm premature rupture of membranes (PPROM) patients and the control group with intact membranes. We also hypothesized whether serum IL-22 upregulation might contribute to defense against inflammatory responses and improve the pregnancy outcomes.Material and methods: We performed this prospective case-control study between 24–34 weeks of pregnancy. We enrolled 40 singleton pregnant patients with PPROM and 40 healthy gestational age- and gravidity-matched patients without PPROM. The degree of association between variables and IL-22 were calculated by Spearman correlation coefficients where appropriate. Scatter plots were given for statistically significant correlations. ROC curve was constructed to illustrate the sensitivity and specificity performance characteristics of IL-22, and a cutoff value was estimated by using the index of Youden.Results: Maternal serum IL-22 levels were significantly higher in PPROM patients (60.34 ± 139.81 pg/mL) compared to the participants in the control group (20.71 ± 4.36 pg/mL, p &lt; 0.001). When we analyze the area under the ROC curve (AUC), the IL-22 value can be considered a statistically significant parameter for diagnosing PPROM. According to the Youden index, a 23.86 pg/mL cut-off value of IL-22 can be used to diagnosing PPROM with 72% sensitivity and 61.5% specificity. There was no positive correlation between serum IL-22 levels and maternal C-reactive protein (CRP) value, procalcitonin value, latency period, birth week, birth weight, and umbilical cord blood pH value.Conclusions: Maternal serum IL-22 levels were significantly higher in PPROM patients than healthy pregnant women with an intact membrane. We suggest that IL-22 might be a crucial biomarker of the inflammatory process in PPROM

Aliphatic Polyurethane Films Based on Hexamethylene Diisocyanate and Saccharides for Biocompatible Transparent Coating on Optic Medical Devices

Polyurethanes are widely used in daily life, from the textile industry to medical applications. In this study, a biocompatible and transparent coating from polyethylene glycol-based polyurethanes including different type of saccharide (xylose as monosaccharide, sucrose as disaccharide, or starch as polysaccharide) is prepared. Prepared optically transparent polyurethanes are characterized with different instrumental analysis techniques and contact-angle measurements. Thermogravimetric analysis data allow understanding that the synthesized saccharide based polyurethanes are resistant to high temperatures, which means that medical devices can be easily coated with one of the saccharide-based polymers during the manufacturing process. The study results also show that synthesized polyurethane samples having a different kind of saccharides present high biocompatibility and transparency properties via In vitro cytotoxicity analysis and optic transparency tests. For xylose, sucrose, or starch containing polyurethanes, the tranmittance values are 97.72%, 85.20%, and 89.23%, respectively. In addition, scanning electron microscope images show that the samples also have smooth surfaces which can be used for proper coating of medical devices. Consequently, this manuscript addresses synthesis and characterization of the optically transparent polyurethanes based on specific saccharides for biocompatible and transparent surfaces especially in optic medical devices such as colonoscopy applications and laparoscopic detection probes.Scientific and Technical Research Council of Turkey (TUBTAK) [111T104]This study was supported by a grant (111T104) to Burhan ATES from The Scientific and Technical Research Council of Turkey (TUBTAK)
