The aim of this study was to investigate the effects of modelling, collaborative and game-based learning on geometry success in third-grade students. These approaches were applied to geometry instruction in nature on the success of students in geometry. The students’ views about geometry activities were also examined. Explanatory design, one of the mixed methods in which qualitative and quantitative methods are both used, was used in the study. The study used a randomized pretest-posttest control group design for the quantitative data; phenomenological study, one of the qualitative research designs, provided the study’s qualitative dimension. The study group consisted of 101 third-grade students attending three different public primary schools. There were 65 participants in the experimental group and 36 in the control group. The quantitative data were collected by a geometry success test and the qualitative data were collected through a structured interview form. The quantitative findings obtained at the end of the study revealed that the students’ success in geometry was greatest in the modelling group. Qualitative findings showed that geometry activities in nature were more effective than in-class activities.

Background Increased rates of cardiac events at the time of natural disasters have been reported. However, the relationship between myocardial infarctions and earthquakes is less clear. We report on the rate of myocardial infarction with no obstructive coronary artery (MINOCA) disease during the 2023 Turkiye earthquakes. Methods All patients with a positive troponin undergoing a coronary angiogram at the Adana City Training and Research Hospital 2 months prior and 2 months subsequent to the February 6th, 2023, Turkiye earthquakes were included. Patients with MINOCA were identified. Multivariate logistic regression analysis was performed to determine variables associated with a diagnosis of MINOCA. Results 619 patients underwent angiography during the study period—479 prior and 140 subsequent to the earthquake. The median age was 61 years and 73% male. MINOCA was diagnosed in 7.8% of the cohort. MINOCA was higher in the postearthquake period (pre: 3.8% vs. post: 21.4%; p < 0.001). The time period after the earthquake had the highest odds of a diagnosis of MINOCA (odds ratio: 5.76; 95% confidence interval: 2.90–11.44). Survival to hospital discharge was higher in the postearthquake period (pre: 89.4% vs. post: 97.9%; p < 0.001). Conclusion The rate of MINOCA increased after the Turkiye earthquakes on February 6th, 2023. This knowledge provides new insight into the spectrum of myocardial infarction after natural disasters. Our work also highlights a potential survivorship bias, which may confound studies reporting on cardiac events after natural disasters. Future work to assess the potential long‐term adverse consequences of MINOCA in this population is suggested.

Purpose The aim of this study was to evaluate the relationship between the weight status of sleeve gastrectomy patients during the first two postoperative years and the frequency of dietician interviews. Materials and Methods This was a retrospective cross-sectional study, and the subjects were patients who had surgery at a special obesity clinic, Bariatriklab, in Istanbul, Turkey, between February 01, 2014, and February 01, 2018.The mean age ± standard deviation of the participants was 38.8 ± 11.9 years. The mean body mass index (BMI) ± standard deviation was 44.2 ± 6.1 kg/m 2 preoperatively. The preoperative (pre-op) and 12-, 18-, and 24-month postoperative (post-op) weights and the frequency of interviews with dieticians for 2 years after the operation were collected, and statistical analysis was performed using SPSS ver. 23.0. Results A total of 247 laparoscopic sleeve gastrectomy (LSG) patients, 161 women (65.2%) and 86 men (34.8%), were evaluated in this study. As the frequency of dietician interviews increased in the first year, the amount of excess weight loss (EWL) increased in the second year ( p  < 0.01). In addition, as the frequency of dietician interviews increased in the second year, the amount of EWL in the second year decreased ( p  < 0.01). The frequency of dietician counseling among participants who did not experience weight loss between 12 and 24 months was significantly higher than that among those who experienced weight loss ( p  < 0.05). Conclusion It should not be forgotten that bariatric surgery requires teamwork, and patients should be cared for with an interdisciplinary approach. Dieticians play an important role in changing nutritional habits and making them sustainable.

The purpose of this study is to test a model that predicts the level of technology acceptance across pre-service teachers at the faculties of education in Turkey. The relationship among the factors that have influence on technology acceptance was investigated. Adopting a questionnaire developed by Timothy (2009) data was collected from 754 pre-service teacher education students attending five faculties of education. In addition to presenting descriptive statistics of the research variables, correlation, ANOVA, and regression analyses were carried out in the study. For the validity, confirmatory factor analysis (CFA) was used. The results indicated that there is a good fit between the model and data. A path analysis was also conducted to test the model. Contrary to the expectations, self-efficacy was not found to be very effective on technology acceptance levels of pre-service teachers.

Purpose The purpose of this study was to explore further whether depression is associated with problematic eating behaviors in a sample of Turkish bariatric surgery candidates. Methods This descriptive study included 168 consecutively seen bariatric surgery candidates in a university bariatric surgery outpatient. Participants were asked to complete the Dutch Eating Behavior Questionnaire (DEBQ), the Beck Depression Inventory (BDI) and surveys assessing sociodemographic and clinical variables. Correlations and linear regression analyses were performed to evaluate the relationship between clinical and demographic variables. Results Participants had a mean age 37.7 ± 11.3 years and BMI of 46.4 ± 6.7 kg/m 2 (SD = 6.7). According to BDI scores, 75.5 % of the patients had mild, moderate, or severe depressive symptomatology. Lower levels of depressive symptoms were associated with higher levels of restrictive eating ( r  = −0.17; p  = 0.04), whereas higher levels of depressive symptoms were associated with more frequent eating in response to both internal ( r  = 0.3; p  = 0.002) and external ( r  = 0.2; p  = 0.04) cues. The BDI scores were significantly associated with increased external eating ( ß  = 0.03, p  < 0.02) and emotional eating ( ß  = 0.03, p  < 0.002) scores. BMI ( β  = −0.02, p  = 0.02 > 0.1) was not associated with DEBQ total scores. Conclusions This research suggests that mild, moderate or severe depressive symptoms are observed in most of the bariatric surgical candidate patients. There is a positive correlation between severity of depression and emotional/external eating behaviors, and a negative correlation between severity of depression and restrictive eating behavior. Additional research is needed to determine whether treating depression preoperatively can assist with alleviating problematic eating behaviors.

Background/Objectives: This randomized controlled trial aimed to evaluate the effects of casein-enriched milk (CEM) consumption and its timing (presleep vs. during the day) in the early postoperative period on body composition, muscle strength, physical function, and biochemical parameters in individuals undergoing laparoscopic sleeve gastrectomy (SG). Methods: Forty-five adults (60% female, 40% male; mean age 35.1 ± 9.7 years; mean BMI 41.4 ± 4.9 kg/m2) undergoing SG were randomly assigned to three groups: (1) 15 g protein CEM (12 g casein) presleep, (2) the same CEM during the day, or (3) standard-protein diet without supplementation. The primary endpoint was change in fat-free mass (FFM) at 12 weeks; secondary endpoints included handgrip strength, 30 s sit-to-stand test, and serum total protein, albumin, and prealbumin. Assessments were performed preoperatively and at weeks 4, 8, and 12. Results: No significant differences were found between the groups in terms of body composition, muscle strength, or physical performance measurements (p > 0.05). However, a significant increase in handgrip strength was observed over time in Groups 1 and 2 (p < 0.05), which was not observed in Group 3. Prealbumin levels at week 12 were 0.3 ± 0.0 mg/dL in Group 1 and 0.2 ± 0.0 mg/dL in Group 2, both higher than 0.2 ± 0.0 mg/dL in Group 3 (p < 0.05). No significant differences were found in albumin and total protein levels (p > 0.05). Conclusions: Early postoperative CEM consumption following SG did not significantly affect body composition or physical performance; however, the higher prealbumin levels indicate that this marker may be more sensitive in detecting early protein response, highlighting its potential clinical relevance in monitoring nutritional status after bariatric surgery.

The aim of this study was to investigate the effects of activity based learning on sixth grade students’ mathematics achievement in comparison to traditional learning, and determine their attitudes towards activities. Experimental research design with pretest-posttest control group was applied in the study. The participants, which included 78 sixth grade students, were previously divided into two groups by random assignment. One group received traditional learning and the other group received activity based learning. The study was carried out for four weeks on the mathematics subject of “integers”. For collecting data the mathematics success test and the Likert type attitudes towards mathematics activities scale were used as pretest and posttest. As a result, the academic achievement for both groups were positive increased. On the other hand, while the attitudes towards activities of students’ in the experiment group decreased significantly, they increased in the control group.

PurposeLSG surgery is used for surgical treatment of morbid obesity. Obesity, anesthesia, and pneumoperitoneum cause reduced pulmoner functions and a tendency for atelectasis. The alveolar “recruitment” maneuver (RM) keeps airway pressure high, opening alveoli, and increasing arterial oxygenation. The aim of our study is to research the effect on respiratory mechanics and arterial blood gases of performing the RM in LSG surgery.Materials and MethodsSixty patients undergoing LSG surgery were divided into two groups (n = 30) Patients in group R had the RM performed 5 min after desufflation with 100% oxygen, 40 cmH2O pressure for 40 s. Group C had standard mechanical ventilation. Assessments of respiratory mechanics and arterial blood gases were made in the 10th min after induction (T1), 10th min after insufflation (T2), 5th min after desufflation (T3), and 15th min after desufflation (T4). Arterial blood gases were assessed in the 30th min (T5) in the postoperative recovery unit.ResultsIn group R, values at T5, PaO2 were significantly high, while PaCO2 were significantly low compared with group C. Compliance in both groups reduced with pneumoperitoneum. At T4, the compliance in the recruitment group was higher. In both groups, there was an increase in PIP with pneumoperitoneum and after desufflation this was identified to reduce to levels before pneumoperitoneum.ConclusionAdding the RM to PEEP administration for morbidly obese patients undergoing LSG surgery is considered to be effective in improving respiratory mechanics and arterial blood gas values and can be used safely.
