Public opinions and beliefs about the treatment of depression in urban Turkey

Abstract: Although attitudes towards psychiatric illness influence its presentation, detection, recognition, treatment adherence and rehabilitation, the lay public's opinions and beliefs about the treatment of depression have not been investigated sufficiently. The aim of this study was to determine public opinions and beliefs about the treatment of depression and the influence of perception and causal attributions on attitudes towards treatment of depression in urban areas. This study was carried out with a representative sample in Istanbul, which is the biggest metropolis in Turkey. Seven hundred and seven subjects completed the public survey form which consisted of 32 items rating attitudes towards depression. The public believes that psychological and social interventions are more effective than pharmacotherapy, and that the medicines used in treatment of depression are harmful and addictive. There was a general reluctance to consult a physician for depression, and psychiatrists were felt to be more helpful than general practitioners. The public viewed depression as treatable. A high educational level and perceiving depression as a disease is associated with positive beliefs and opinions about the treatment of depression; but the perception of depressive patients as aggressive is associated with negative beliefs and opinions about the treatment of depression. The beliefs that “psychological and social interventions are more effective than pharmacotherapy” and “antidepressants are harmful and addictive” must specifically be taken into account in clinical practice and in anti-stigma campaigns. Additional studies are needed to understand the public's tendency to conceptualise depression as a psychosocial problem. In clinical practice, depression should be introduced as a bio-psychosocial disease whatever its cause: biological, psychological or social. In addition, the differences between extreme worry and disease, and the lack of aggressiveness of depressive patients, must be emphasised.

Comparative morphological differences between umbilical cords from chronic hypertensive and preeclamptic pregnancies.

Abstract: To compare morphological changes in the umbilical cords from chronic hypertensive and preeclamptic patients having normal or pathological umbilical artery Doppler ultrasonographic results. Umbilical cords from 34 normotensive, 31 chronic hypertensive and 70 preeclamptic women with normal and abnormal Doppler flow velocity waveforms (FVW) at 35-40 gestational weeks were studied. Morphological changes in the umbilical cords were examined on formalin-fixed, paraffin-embedded sections. The total umbilical cord area, total vessel area, and wall thickness of umbilical vessels were measured in systematic random samples using unbiased stereology methods. An ANOVA test was used for statistical analysis. In the chronic hypertensive and preeclamptic groups with normal Doppler FVW, the thickness of the umbilical cord vessels remained nearly constant, whereas both the total area and the lumen area were reduced. These changes correlate with the histopathological findings, suggesting a mainly vasoconstrictive effect. By contrast, analysis of the preeclamptic group with pathologic Doppler FVW showed a comparable reduction of all parameters of the umbilical cord. Histopathological findings were related to smaller, contracted smooth muscle cells of the vessel wall, which is suggestive of a predominant hypoplastic mechanism. As a result of reduced uteroplacental perfusion, fetal hypoxia and intrauterine growth retardation become unavoidable in preeclampsia. The histopathological changes in the umbilical cord between the chronic hypertensive and preeclamptic patients depend on the Doppler results. In conclusion, the umbilical artery Doppler FVW indices provide good values for predicting intrauterine growth retardation in preeclamptic patients.

Premenstrual syndrome in Turkish medical students and their quality of life.

Abstract: This study aimed to analyse the frequency and symptoms of premenstrual syndrome (PMS) and its effect on quality of life in medical students. Sociodemographic data, a symptom calendar for the following consecutive two menstrual periods and SF-36 quality of life questionnaire were collected. A total of 228 students joined the survey. The average age of the students was 20.77 ± 1.90. The frequency of PMS was 91.8%. The most frequent symptoms were abdominal bloating (89.5%), irritability (88.3%) and breast tenderness (82.6%). Quality of life scores ranged from 17.00 to 97.00 and were lowest in the severe PMS group. Alcohol consumption, stress events and fat rich diets increased the severity of PMS. Family history significantly affected the severity of PMS and quality of life scores. Premenstrual syndrome was found to be a frequent entity among medical students and seemed to affect quality of life in a moderate way.

ACE I/D gene polymorphism and aerobic endurance development in response to training in a non-elite female cohort.

Abstract: Aim. The aim of this study was to investigate the association between ACE gene polymorphism and short- and medium-duration aerobic endurance performance improvements in response to the same training regimen in a non-elite female cohort. Methods. Fifty-five female non-elite Caucasian Turkish athletes trained to enhance running speeds corresponding to 70% and 90% of heart rate reserve (V-HRR70 and V-HRR90 respectively) 30 min running speed performance (V-30min) 3 times per week, for 6 weeks. ACE gene polymorphisms studied by PCR analysis. Results. The distribution of genotypes in the whole cohort was 21.8%, 41.8%, 36.4% for II (n=12), ID (n=23) and DD (n=20), respectively. Subjects with ACE II genotype had significantly higher improvements in V-30min and V-HRR70 than the ACE DD group (P ID>DD (P ID>II (P<0.01) observed in V-HRR90. Conclusion. ACE II genotype may related with better improvements in medium duration aerobic endurance performance whilst ACE DD genotype seems to be more advantageous in performance enhancement in shorter duration and higher intensity endurance activities.
