Article Abstract
Background: Spirometry is one of the basic methods used in the diagnosis, treatment, and follow-up of respiratory disease. Spirometric test results that do not comply with international standards may be misinterpreted and lead to misdiagnosis and treatment. We aimed to assess the tests of patients that meet the "American Thoracic Society/European Respiratory Society (ATS/ERS) 2019" recommendations, to identify the most common errors, and to explore patient characteristics possibly associated with failure to reach these standards.
Methods: A total of 1000 spirometries performed between January and December 2023 were randomly selected retrospectively. Spirometric maneuvers were evaluated for meeting the acceptability criteria of the ATS/ERS 2019 guidelines.
Results: The acceptability spirometry rate was 62.5%. The most frequently unmet criterion was failure to meet any of the three ends of forced expiration at 20.7%. There was no significant difference between male and female in terms of the acceptability of maneuvers. The 45-59 and 60-74 age groups were statistically more significant than the younger and older. Smoking, diagnosis of chronic obstructive pulmonary disease, and number of spirometry practices were significantly associated with conformity to test acceptability criteria. The forced expiratory volume in 1 second (FEV1) divided by the forced vital capacity, FEV1, and forced expiratory times had a statistically significant independent effect on the acceptability of spirometric maneuvers.
Conclusion: Nearly one-third of the tests performed by an experienced technician in a tertiary care hospital did not meet the acceptability criteria. Our study shows the importance of the learnability of maneuvers through repeated spirometry experiences.

Purpose Of Review: This review examines cardiovascular disease (CVD) risk prediction models relevant to older adults, a rapidly expanding population with elevated CVD risk. It discusses model characteristics, performance metrics, and clinical implications.
Recent Findings: Some models have been developed specifically for older adults, while several others consider a broader age range, including some older individuals.

Background: Recent studies suggest that large language models (LLMs) such as ChatGPT are useful tools for medical students or residents when preparing for examinations. These studies, especially those conducted with multiple-choice questions, emphasize that the level of knowledge and response consistency of the LLMs are generally acceptable; however, further optimization is needed in areas such as case discussion, interpretation, and language proficiency. Therefore, this study aimed to evaluate the performance of six distinct LLMs for Turkish and English neurosurgery multiple-choice questions and assess their accuracy and consistency in a specialized medical context.

Background: High-dose-rate (HDR) brachytherapy is essential in the treatment of locally advanced cervical cancer. While Iridium-192 (Ir-192) is commonly used, its short half-life imposes logistical and financial constraints, particularly in low- and middle-income countries (LMICs). Cobalt-60 (Co-60), with a longer half-life and lower operational costs, is a viable alternative.

Objective: Ex vivo lung perfusion (EVLP) has resulted in a significant increase in the use of extended-criteria donor lungs without negatively impacting survival outcomes. However, in-house EVLP is resource-intensive, thereby limiting accessibility. Remote, centralized EVLP (rc-EVLP) has been used with acceptable outcomes in a highly protocolized feasibility study, although has not been assessed in a clinical setting.

Background: Severe acute malnutrition (SAM) affects about 20 million under-5 children and contributes to one million child deaths annually. Apart from the presence of clinical management protocols capable of reducing case fatality by 1%-5%, case fatality in hospitals in developing countries averages 20%-30% and has remained the same since the 1950s.
Objective: This study aimed to assess treatment outcomes and associated factors of severe acute malnutrition among under-5-year-old children admitted to Jigjiga city public hospitals.
