Comparison of samples found positive by anti-HCV screening test with line immunoassay and determination of threshold value.
This study aimed to compare the serum samples found reactive (≥1-≤20 signal-to-cutoff ratio) with Elecsys antibodies to hepatitis C virus screening test with innogenetics-line immunassay hepatitis C Virus Score test and to determine the most appropriate threshold value for our country, since positive results close to the cutoff value cause serious problems in routine diagnostic laboratories. ⋯ It was concluded that with further studies on this subject, each country should determine the most appropriate S/Co value for its population, and thus it would be beneficial to reduce the problems such as test repetition and cost increase.

Lung age and respiratory muscle strength in female volleyball players.
Lung age estimation is a useful approach to determine pulmonary pathologies. In literature, no studies have evaluated and compared lung age in athletes with healthy volunteers. This study aims to compare lung age and respiratory muscle strength in female volleyball players and age-matched healthy volunteers. ⋯ The lung age and respiratory muscle strength of female volleyball players were better than healthy volunteers. Regular training in female volleyball players may improve respiratory functions and lung age.

The aim of this study was to describe chest computed tomography image findings in patients with COVID-19. ⋯ In a dynamic disease with a broad clinical spectrum such as COVID-19, radiologists can cooperate in a better patient management. On wisely indicated chest computed tomography scans, the fast identification of poor prognosis findings could advise patient management through hospital care facilities and clinical team decisions.

Evaluation of the olfactory bulb volume and morphology in patients with coronavirus disease 2019: can differences create predisposition to anosmia?
This study aimed to investigate whether the volume and morphology of the olfactory bulb are effective in the occurrence of anosmia in patients after COVID-19 infection. ⋯ According to our results, the olfactory bulb volume does not affect the development of anosmia after COVID-19. However, it is striking that the bulb morphology significantly differs between the patients with and without anosmia. It is clear that the evaluation of COVID-19-associated smell disorders requires studies with a larger number of patients and a clinicoradiological approach.

Factors associated with postoperative complications following appendectomy in elderly patients.
Appendicitis in elderly patients is more challenging due to delayed presentation and higher comorbidities, which are associated with increased postoperative morbidity. The aim of this study was to evaluate factors that predict 30-day complications in elderly patients undergoing appendectomy. ⋯ Older patients undergoing appendectomy tend to have poorer outcomes than younger patients. Therefore, it is critical to identify factors that could reduce the possibility of adverse outcomes in this frail population. The results of this study suggest that obesity, chronic obstructive pulmonary disease, and an open approach are independent factors for complications in elderly patients undergoing appendectomy.
