Objective: The high prevalence of vitamin D deficiency in the population causes physicians to request more vitamin D tests and increases laboratory costs. It is aimed at investigating the demanded numbers and cost analyzes of 25-hydroxyvitamin D (25(OH)D) tests with the big data obtained from the national information health system of the Turkish Ministry of Health.
Methods: Between 2017 and 2018, all inpatient and outpatient tests and 25(OH)D tests in all medical biochemistry laboratories in Turkiye were determined based on department and institution type. The cost amount, distribution among health institutions, and test request rates were calculated. In both years, the top ten most expensive tests, according to health institutions, were evaluated.
Results: The total number of medical biochemistry tests performed in 2017 and 2018 was 1.424.948.155 and 1.713.134.326, respectively. The number of 25 (OH)D tests analyzed in the same years was 8.698.393 and 13.919.127, respectively. When the data of the 2 years are compared, the consumption of 25 (OH)D tests increased by 37% in General hospital laboratories, whereas it increased by 115.09% in primary health laboratories. When all health institutions were evaluated, the increase rate in 25 (OH)D test demand was 60%, while the cost increase rate was 23%.
Conclusion: This report showed that the demands for 25(OH)D testing are increasing steeply, especially in primary health-care facilities. In this direction, laboratory information system test demand restrictions in accordance with national and international guidelines are important issues for policymakers.

The paper proposes a multi-rigid-body system state identification method based on self-healing model in order to improve the accuracy and reliability of CNC machine tools. Firstly, considering the influence of the joint surface, the Lagrange method is used to establish the mechanical model of the multi-rigid-body system. We input acceleration information and use the second-order modulation function to complete the online real-time identification of the joint surface parameters, thereby establishing the self-healing mechanical model of the multi-rigid-body system.

Fluid administration is widely used to treat hypotension in patients undergoing veno-venous extracorporeal membrane oxygenation (VV-ECMO). However, excessive fluid administration may lead to fluid overload can aggravate acute respiratory distress syndrome (ARDS) and increase patient mortality, predicting fluid responsiveness is of great significance for VV-ECMO patients. This prospective single-center study was conducted in a medical intensive care unit (ICU) and finally included 51 VV-ECMO patients with ARDS in the prone position (PP).

In order to plan and facilitate the culture of personalized / precision medicine in medical practices within any healthcare institution, it is requisite for healthcare professionals like clinicians to have a clear understanding and approach towards the practices of personalized genetic testing. This nationwide cross-sectional study aimed to measure the perceptions and knowledge of clinicians towards personalized genetic testing and assess their current practices of personalized genetic testing in clinical settings through an online self-administered questionnaire in Saudi Arabia. The results of the study revealed that almost two-fifths of participants were responsible for ordering genetic tests directly (39.

Preserving the ability to vividly recall emotionally rich experiences contributes to quality of life in older adulthood. While prior works suggest that moderate-intensity physical activity (MPA) may bolster memory, it is unclear whether this extends to emotionally salient memories consolidated during sleep. In the current study, older adults (mean age = 72.
