    (Mattioli 1885, 2019) Yagmur R.; Isik O.; Kilic Y.; Akyuz M.
    Study Objectives: Dehydration causes various loss of physical and physiological functions and also thyroid hormones are important for maintaining the normal physiological function of the body and regulate basic metabolism in the human body. The aim of this study was to examine the effect of pre-competition dehydration on elite wrestlers' thyroid hormones levels. Sixty-nine elite wrestlers participated in the study. Methods: The retrospective research model was used in the study. In previously obtained blood samples were determined Sodium (Na+), Blood Urea Nitrogen (BUN), Glucose, Potassium (K), Triiodothyronine (T3), Thyroxine (T4) and Thyroid Stimulating Hormone (TSH) levels. The wrestlers Posm levels were calculated using a mathematical formula and Posm levels >290 who wrestlers as the dehydration group and Posm levels ≤290 who wrestlers as the euhydration group were divided into two groups. The Kolmogorov-Smirnov test was used for the normality test of the data. The independent samples t-test was used in the analysis of the obtained data. Significance was set at 0.05. Results: According to the results of this study, it was determined that ∼45% of pre-competition wrestlers were exposed to dehydration. When the dehydration and euhydration groups were compared, there was a significant difference in BUN and Na+ levels as the hydration markers and there was no difference in Glucose and K levels. When the difference between thyroid hormones levels was examined, it was found that there was a statistical difference between T3 levels and there was no difference between T4 and TSH levels. Conclusion: T3 levels of elite wrestlers were lower in dehydration group than the euhydration group, whereas T4 and TSH levels were not different between both groups. © 1885 Mattioli.

    Background: Appendicitis is the most prevalent surgical emergency. The negative appendicectomy rate and diagnostic uncertainty are important concerns. This study aimed to assess the effectiveness of current appendicitis risk prediction models in patients with acute right iliac fossa pain. Methods: A nationwide prospective observational study was conducted, including all consecutive adult patients who presented with right iliac fossa pain. Diagnostic, clinical and negative appendicectomy rate data were recorded. The Alvarado score, Appendicitis Inflammatory Response (AIR), Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) and Adult Appendicitis Score systems were calculated with collected data to classify patients into risk categories. Diagnostic value and categorization performance were evaluated, with use of risk category-based metrics including 'true positive rate' (percentage of appendicitis patients in the highest risk category), 'failure rate' (percentage of patients with appendicitis in the lowest risk category) and 'categorization resolution' (true positive rate/failure rate). Results: A total of 3358 patients from 84 centres were included. Female patients were less likely to undergo surgery than men (71.5% versus 82.5% respectively; relative risk 0.866, 95% c.i. 0.834 to 0.901, P < 0.001); with a three-fold higher negative appendicectomy rate (11.3% versus 4.1% respectively; relative risk 2.744, 95% c.i. 2.047 to 3.677, P < 0.001). Ultrasonography was utilized in 56.8% and computed tomography in 75.2% of all patients. The Adult Appendicitis Score had the best diagnostic performance for the whole population; however, only RIPASA was significant in men. All scoring systems were successful in females patients, but Adult Appendicitis Score had the highest area under the receiver operating characteristic curve value. The RIPASA and the Adult Appendicitis Score had the best categorization resolution values, complemented by their exceedingly low failure rates in both male and female patients. Alvarado and AIR had extremely high failure rates in men. Conclusion: The negative appendicectomy rate was low overall, but women had an almost three-fold higher negative appendicectomy rate despite lower likelihood to undergo surgery. The overuse of imaging tests, best exemplified by the 75.2% frequency of patients undergoing computed tomography, may lead to increased costs. Risk-scoring systems such as RIPASA and Adult Appendicitis Score appear to be superior to Alvarado and AIR. © 2024 The Author(s). Published by Oxford University Press on behalf of BJS Foundation Ltd.
