The utility of capnography in determining the risk of major cardiac adverse events in patients with atypical chest pain.

INTRODUCTION: Various scoring systems have been developed to safely rule out the diagnosis of acute coronary syndrome. Furthermore, the efficacy of these scoring systems in predicting the risk of major adverse cardiac events (MACE) is debated. Our aim was to compare parameters such as Integrated Pulmonary Index (IPI) and End Tidal Carbon Dioxide (etCO2) measured in the emergency department with the HEART score in terms of its success in predicting the risk of major adverse cardiac events. METHOD: Patients with atypical chest pain were registered for the study by the emergency room physician. The patients were investigated regarding gender, age, background characteristics, prognostic accuracy of etCO2, IPI, MACE, and HEART scores. RESULTS: As a result of the analysis, higher HEART Score and lower etCO2 values were determined in the MACE group compared to the group without MACE. ROC analysis was performed to determine the power of IPI, HEART Score, and etCO2 to predict MACE. The findings revealed that IPI significantly predicted MACE with an AUC value of 0.737. CONCLUSION: In our study, although the highest sensitivity values in determining the risk of 30-day MACE belonged to the HEART score, etCO2 and IPI might be other parameters that could be used to determine the risk of 30-day MACE.

The impact of meteorological parameters on the number of applications to the emergency department with acute urticaria: A retrospective study.

The study aimed to investigate the relationship between the patients who applied to the emergency department with acute urticarial and meteorological factors and determine the associated weather conditions. The relationship between acute urticaria patients who applied to the emergency department of a training and research hospital in a city with high altitude and continental climate characteristics in the eastern part of Turkey between January 2019 and December 2019 and meteorological data was evaluated retrospectively. The necessary data for the weather were obtained from the data of the Erzurum Meteorology Directorate, and the patient data were obtained from the hospital information management system and patient files. The meteorological data of the patients at the date of admission and the characteristics of the patients at that date were compared. The study identified 691 patients who applied to the emergency department diagnosed with urticaria in 2019. According to the seasons, it was observed that the patients applied most frequently in the summer months [n = 239; 34.6%]. In the univariable regression model, which was created by taking the values of weather events as a reference on the days when the urticaria presentation was not observed (Group I), it was determined that every 1-hour increase in the sunshine hour increased the probability of urticaria by 7.4% (p = 0.018). When the meteorological parameters on the days without urticaria (Group I) and the days with urticaria presentation (Group II) were compared, the sunshine hours were 7.9 (4.0-10.6) hours in Group II and 6.65 (3.3-8.85) hours in Group I (p = 0.001). Regarding relative humidity, higher humidity rates were observed in Group I compared to Group II (p = 0.009). In terms of mean temperature, daily maximum, and minimum temperature, higher temperature rates were detected in Group II (p<0.001). A relationship was determined between urticaria attacks and relative humidity and daily maximum and minimum temperature in patients who applied to the emergency department with acute urticaria.

Comparison of unilateral and bilateral microdissection testicular sperm extraction (MD-TESE) in patients with non-obstructive azoospermia: a prospective study.

OBJECTIVE: To compare sperm retrieval rates between unilateral and bilateral microdissection testicular sperm extraction (MD-TESE) procedures in patients with non-obstructive azoospermia and to contribute to the literature by comparing them with literature data. METHODS: This prospective study included 84 males with primary infertility who had azoospermic NOA, who had been married for at least one year, and whose female partners did not have a history of infertility. The study was conducted between January 2019 and January 2020. MD-TESE was applied bilaterally to 48% (n:41) (Group 1) and unilaterally to 52% (n:43) (Group 2) of the patients, and sperm retrieval rates were compared. RESULTS: There was no statistically significant difference between Group 1 patients and Group 2 patients in terms of sperm availability (61%, 56.5%, p=0.495, respectively). In addition, while no complications were observed in unilateral MD-TESEs, 3 complications were observed in bilateral MD-TESEs. CONCLUSIONS: In our study, it was determined that there was no significant difference between the groups in terms of sperm availability in patients with NOA. Considering the operative time and complication rates of bilateral MD-TESE in patients diagnosed with NOA and the possible MD-TESE procedures that may be performed later, we believe that unilateral MD TESE is a more preferable procedure for the patient and surgeon in this patient group.
