Postnatal depression in turkey: epidemiological and cultural aspects.

Abstract: Background In some periods of a woman's life the risk of depression increases and the postnatal period is one of these. The prevalence and the risk factors of postnatal depression are not systematically studied in Turkey. The aim of this study is to investigate the epidemiological aspects and the cultural factors that may affect postnatal depression in our country. Method According to the records of ten primary health care centres in Manisa, a city in western Turkey, there were 1,337 women who had given birth in the previous 6 months. A sample group of 317 mothers were randomised among these women and 257 (81.7 %) of the sample group could be reached. Data were collected by use of the Edinburgh Postnatal Depression Scale and a questionnaire on sociodemographic variables designed for this study. Results The mean depression score was found to be 7.54 ± 4.66. When the cut-off point was taken into consideration, 14 % of mothers had a syndromal depression. The factors which affected the prevalence of depression were the number of living children, living in a shanty, being an immigrant, serious health problems in the baby, previous psychiatric history, psychiatric disorder in the spouse, and having bad relations with the spouse and his parents. Conclusion These findings revealed that the prevalence of postnatal depression in the Manisa province and the factors affecting it were very similar to other studies; but the negative impact of bad relations of the mother with her family-in-law on postnatal depression seems to be a distinguishing aspect of Turkish culture.

A Geotraverse Across Northwestern Turkey: Tectonic Units of the Central Sakarya Region and their Tectonic Evolution

Abstract: Abstract In the Central Sakarya area of Turkey there are two main Alpine continental units, separated by a south verging ophiolitic complex which represents the root zone of the İzmir-Ankara Suture Belt. The Central Sakarya Terrane in the north includes two ‘Variscan’ tectonic units in its basement. The Söğüt Metamorphic rocks represent a Variscan ensimatic arc complex and the Tepeköy Metamorphic rocks are characteristically a forearc-trench complex. The unconformably overlying Triassic Soğukkuyu Metamorphic rocks correspond to a part of the Karakaya Formation and are interpreted as a Triassic rift basin assemblage. These units are unconformably overlain by a transgressive sequence of Liassic-Late Cretaceous age that represents the northeastward deepening carbonate platform of the Sakarya Composite Terrane. The middle tectonic unit (the Central Sakarya Ophiolitic Complex) comprises blocks and slices of dismembered ophiolites, blueschists and basic volcanic rocks with uppermost Jurassic-Lower Cretaceous radiolarite-limestone interlayers. Geochemical data from basalt blocks suggest mid-ocean ridge basalt (MORB)- and suprasubduction-type tectonic settings within the Neotethyan İzmir-Ankara Ocean. The southern tectonic unit includes basal polyphase metamorphosed clastic rocks (Sömdiken Metamorphics), intruded by felsic and basic dykes and overlain by thick-bedded marbles. This assemblage is unconformably overlain by continental clastic rocks gradually giving way to thick-bedded recrystallized limestones, cherty limestones and pelagic limestones intercalated with radiolarites, and finally by a thick high pressure-low temperature (HP-LT) metamorphic synorogenic flysch sequence. This succession is identical to the passive continental margin sequences of the Tauride Platform. It is suggested that this passive margin was subducted during the Late Cretaceous in an intraoceanic subduction zone and affected by HP-LT metamorphism. The emplacement of the allochthonous oceanic assemblages and the collision with the Central Sakarya Terrane was complete by the end of the Cretaceous.

Measurements of CP violation in the three-body phase space of charmless B-+/- decays

Abstract: The charmless three-body decay modes B±→K±π+π−, B±→K±K+K−, B±→π±K+K− and B±→π±π+π− are reconstructed using data, corresponding to an integrated luminosity of 3.0 fb−1, collected by the LHCb detector. The inclusive CP asymmetries of these modes are measured to be ACP(B±→K±π+π−)=+0.025±0.004±0.004±0.007,ACP(B±→K±K+K−)=−0.036±0.004±0.002±0.007,ACP(B±→π±π+π−)=+0.058±0.008±0.009±0.007,ACP(B±→π±K+K−)=−0.123±0.017±0.012±0.007, where the first uncertainty is statistical, the second systematic, and the third is due to the CP asymmetry of the B±→J/ψK± reference mode. The distributions of these asymmetries are also studied as functions of position in the Dalitz plot and suggest contributions from rescattering and resonance interference processes.
