Türkiye'de koroner yoğun bakım ünitelerindeki hastane içi mortalite (MORCOR-TURK) çalışmasında hasta temel karakteristikleri ve öngördürücüleri

OBJECTIVE: The MORtality in CORonary Care Units in Türkiye (MORCOR-TURK) trial is a national registry evaluating predictors and rates of in-hospital mortality in coronary care unit (CCU) patients in Türkiye. This report describes the baseline demographic characteristics of patients recruited for the MORCOR-TURK trial. METHODS: The study is a multicenter, cross-sectional, prospective national registry that included 50 centers capable of 24-hour CCU service, selected from all seven geographic regions of Türkiye. All consecutive patients admitted to CCUs with cardiovascular emergencies between September 1-30, 2022, were prospectively enrolled. Baseline demographic characteristics, admission diagnoses, laboratory data, and cardiovascular risk factors were recorded. RESULTS: A total of 3,157 patients with a mean age of 65 years (range: 56-73) and 2,087 (66.1%) males were included in the analysis. Patients with arterial hypertension [1,864 patients (59%)], diabetes mellitus (DM) [1,184 (37.5%)], hyperlipidemia [1,120 (35.5%)], and smoking [1,093 (34.6%)] were noted. Non-ST elevation myocardial infarction (NSTEMI) was the leading cause of admission [1,187 patients (37.6%)], followed by ST elevation myocardial infarction (STEMI) in 742 patients (23.5%). Other frequent diagnoses included decompensated heart failure (HF) [339 patients (10.7%)] and arrhythmia [272 patients (8.6%)], respectively. Atrial fibrillation (AF) was the most common pathological rhythm [442 patients (14%)], and chest pain was the most common primary complaint [2,173 patients (68.8%)]. CONCLUSION: The most common admission diagnosis was acute coronary syndrome (ACS), particularly NSTEMI. Hypertension and DM were found to be the two leading risk factors, and AF was the most commonly seen pathological rhythm in all hospitalized patients. These findings may be useful in understanding the characteristics of patients admitted to CCUs and thus in taking precautions to decrease CCU admissions

Quaternary uplift rates of the Central Anatolian Plateau, Turkey: insights from cosmogenic isochron-burial nuclide dating of the Kızılırmak River terraces

The Central Anatolian Plateau (CAP) in Turkey is a relatively small plateau (300 × 400 km) with moderate average elevations of ∼1 km situated between the Pontide and Tauride orogenic mountain belts. Kızılırmak, which is the longest river (1355 km) within the borders of Turkey, flows within the CAP and slowly incises into lacustrine and volcaniclastic units before finally reaching the Black Sea. We dated the Cappadocia section of the Kızılırmak terraces in the CAP by using cosmogenic burial and isochron-burial dating methods with 10Be and 26Al as their absolute dating can provide insight into long-term incision rates, uplift and climatic changes. Terraces at 13, 20, 75 and 100 m above the current river indicate an average incision rate of 0.051 ± 0.01 mm/yr (51 ± 1 m/Ma) since ∼1.9 Ma. Using the base of a basalt fill above the modern course of the Kızılırmak, we also calculated 0.05–0.06 mm/yr mean incision and hence rock uplift rate for the last 2 Ma. Although this rate might be underestimated due to normal faulting along the valley sides, it perfectly matches our results obtained from the Kızılırmak terraces. Although up to 5–10 times slower, the Quaternary uplift of the CAP is closely related to the uplift of the northern and southern plateau margins respectively

Anthropometric and Clinical Analyses of the Distal Tibia, Posterior Tibial Tendon, and Flexor Digitorum Longus Tendon on MRI

 This study examined gender-related differences in measurements of the medial malleolus groove (MMG) and tendons passing through it. A total of 103 patients were included, and various measurements were taken. Findings revealed statistically significant differences between genders in MMG depth, width, and length, as well as in the width and thickness of the posterior tibial tendon (PTT) and flexor digitorum longus tendon (FDLT). The study suggests that these measurements can be used for gender differentiation and may have implications in forensic identification and surgical procedures. Additionally, the presence of asymptomatic cases without a detectable MMG highlights the need to consider other pathologies in addition to MMG depth.  This study is important as it contributes to the understanding of gender-related differences in the measurements of the medial malleolus groove (MMG) and associated tendons. By identifying statistically significant differences between genders, such as MMG depth, width, and length, as well as the dimensions of the posterior tibial tendon (PTT) and flexor digitorum longus tendon (FDLT), it enhances our knowledge of anatomical variations between males and females in this region. This information can have practical implications in various fields. For forensic identification, these measurements can aid in gender differentiation when examining skeletal remains or unidentified individuals. In surgical procedures, particularly those involving the MMG and tendons, these measurements can help determine optimal surgical techniques and implant sizing, leading to improved surgical outcomes. Furthermore, the presence of asymptomatic cases without a visible MMG raises awareness of potential variations and other underlying pathologies in the region. Overall, this study provides valuable insights into the anatomical differences in the MMG and tendons between genders, enhancing our understanding and potentially influencing various medical disciplines. </p

Investigation Studies in the Life Experiences of Families of Children with Autism Spectrum Disorders: A Meta-Synthesis Study

Qualitative studies that involved the parents of children diagnosed with autism spectrum disorders tend to focus on the adaptation efforts of parents after learning of the diagnosis and their experiences at the time. Identifying experiences that are associated with their child's ASD and the factors that affect their experiences are important to determine the needs of parents who have children with ASD. The present study uses a meta-synthesis method in a review of qualitative studies to investigate the experiences of parents of children with ASD, with the aim to identify common conclusions. The present study makes a review of 18 studies, selected from national and international literature and published between 2008 and 2017, that met the criteria of the study. All of the studies adopted a phenomenology pattern as a qualitative research method to investigate the life experiences of parents of children with ASD, and an overall assessment of the reviewed studies revealed the following four salient themes: the effects of cultural differences on experiences, coping strategies, labeling and advocacy. Further research may focus on such factors as culture and advocacy, both of which influence the parental experience
