Readability of texts in secondary school mathematics course books

This study aimed to investigate the readability of the fifth-, sixth, seventh and eighth-grade mathematics course books prepared in deference to the 2017 curriculum and distributed to schools by MEB. This study utilized the descriptive document analysis which is a qualitative research method. Readability of the mathematics course books were subjected to a quantitative analysis by Çetinkaya-Uzun Readability Formula. Addressing the readability levels of the texts in secondary mathematics course books, this study performed analyses of average word and average sentence lengths of the texts in secondary school course books. These analyses showed that there is no linear correlation between grade level and word and sentence length averages. Readability scores and levels of the text in the analyzed secondary school mathematics course books are not in parallel with the grade level. Accordingly, readability scores of information and solution texts in the fifth-grade course book were lower than the scores in other grades' course books whereas readability scores of question texts were lower than the scores in all grades' course books but the eighth-grade course book. Readability levels of the text in the analyzed secondary school mathematics course book were found to be on frustration level and educational level. Course books should also include independent texts with readability scores and level

Improvement of long type pepper lines resistant to Tomato Spotted Wilt Virus (TSWV)

Pepper is widely grown vegetable crops after tomato and watermelon in the world. One of the most important diseases on pepper production is caused by Tomato spotted wilt virus (TSWV). The best way for the control of this disease is to use resistant varieties. This study aimed to improve TSWV resistant lines to use as a parent in long type pepper breeding studies. Three genotypes resistant to TSWV were crossed with the susceptible Serademre 8 used to be commercial. Pedigree method was applied as the breeding method. Three populations were self-pollinated for five generations. The progenies for each of populations were tested against TSWV. Mechanical inoculations were performed in each generation and the selected resistant plants were grown for self-pollination to achieve next generation. Molecular tests were applied to the plants in stages F1 and F5. Virulent strain isolated from infected pepper plants was used as a disease material in the mechanical inoculations. CAPS marker (SCAC568) linked to the TSWV resistance gene (Tsw) was used in the molecular test for verification of mechanical test. In this study, 10 lines resistant to TSWV with good features were developed. Some of the obtained TSWV resistant lines have been transferred to private sector seed companies for use in pepper breeding programs

Relationship Between Acute Appendicitis and Platelet Indices in Childhood

Introduction: Appendicitis is the inflammation of the appendix vermiformis. Clinical diagnosis of acute appendicitis in children is still a problem. Platelet indices, platelet distribution width and mean platelet volume have been evaluated for some infectious and inflammatory diseases. In this study, we aimed to investigate whether platelet distribution width values and mean platelet volume were decisive for the diagnosis of appendicitis in children. Methods: In our hospital, 504 pediatric patients who presented with acute abdomen and received the diagnosis of acute appendicitis between 2011 and 2016, and 106 children living in the same region, who attended the pediatric outpatient clinics for general follow-up, were included in the study. The patient and control groups were analyzed for gender, age, platelet count, platelet distribution width and mean platelet volume. A receiver operating characteristic (ROC) curve was drawn to describe the parameters that may be statistically significant. Results: There was a significant difference in platelet distribution width and mean platelet volume values between the two groups (p14.3 fL for platelet distribution width for the diagnosis of appendicitis with a sensitivity, specificity, positive predictive value, and negative predictive value of 77.6%, 85.8%, 96.3%, and 44.6%, respectively. A cut-off value of <9.35 fL for mean platelet volume was used for the diagnosis of appendicitis with a sensitivity, specificity, positive predictive value, and negative predictive value of 78.1%, 81.1%, 95.2%, and 43.9%, respectively. Conclusion: Our results suggest that platelet distribution width and mean platelet volume may be used for the diagnosis of appendicitis in children with the sensitivity of at least 77.6% and 78.1%, respectively. Mean platelet volume and platelet distribution width, which can easily be investigated in complete blood count, may serve as markers for the diagnosis of appendicitis in children, however, further large-scale studies are needed

Survival and Stage in Lung Cancer

Purpose: Lung cancer is the leading cause of cancer death worldwide. Although the 5-year survival rates of for non-small cell lung carcinoma (NSCLC) ranges from 20% to 70%. The present study investigates the rates of early recurrence in a total of 83 patients operated for NSCLC and presents the related findings in reference to the data available in the literature. Materials and Methods: Patients who underwent lung resection for malignancy between March 2019 and September 2021 were retrospectively examined. The patient data, including age, gender, presence of preoperative chemotherapy administration, opera-tions performed, operation dates, pathology results, postoperative staging, survival, and relapses, were documented. Results: A total of 83 patients who underwent lung resection for malignancy between March 2019 and September 2021 were examined. The patients had a median age of 62 years. Of the total number of patients four patients developed recurrence and 79 continued their follow-up without any recurrence. Of the patients who underwent lung resection, eight (9.6%) patients died within the first postoperative 2-year period. The mean survival period of these eight patients was 14.6 months (7–20 months). Conclusion: Although various parameters, such as age, gender, pathological type, and location of the tumor are examined and compared, according to the available data on the long-term survival of surgical patients, it is known that the only parameter that affects survival is the pathological stage of the patient

A Child with Acute Appendicitis Secondary to Blunt Abdominal Trauma: A Case Report and Review of the Literature

We present a child with abdominal pain and vomiting after blunt abdominal trauma (BAT). He had tenderness, guarding and rebound on the bilateral lower quadrant of the abdomen. He had no abrasion on the abdominal skin surface. He had marked leukocytosis and increased C-reactive protein level. Contrast-enhanced abdominal computed tomography revealed inflamed appendicitis. He was operated by pediatric surgeons and, an perforated appendix was illustrated on pathological examination. BAT and acute appendicitis (AA) are independently very frequent issues. In pediatric emergency departments, BAT and AA are very frequent issues, however, coexistence of these two condition in the same patient is rare. This case report and review of the literature showed that occurrence of AA after BAT should be considered by emergency physicians
