The frequency per week was converted to an average frequency per day for statistical analysis. The questionnaire was self-administered by the participants. two.three. Healthcare Symptoms Questionnaire An openly accessible Medical Symptoms Questionnaire (MSQ, File S1 integrated inside the Supplementary Material on the net) from the Departments of Medicine, Mercy Hospital and Maine Medical Center, Portland [31] was completed by every single participant. The MSQ contains 19 domains, most with 4 products, totaling 75 indicators to every of which the patient assigns a Likert scale numerical D1 Receptor Inhibitor Synonyms ranking (0 getting “never” or “seldom” and 4 being “frequently with severe effect”). The 75 questions are divided into 15 key sections. The scores wereInt. J. Environ. Res. Public Overall health 2021, 18,four ofcalculated because the imply with the items per section and the items were also combined in an general MSQ score.

To calculate a total fatigue score, the cumulative sum of all was divided by the total quantity of products. As outlined by the scoring instructions of the PFS, the severity in the fatigue can be classified in accordance with the following severity codes: None (0), Mild (1), Moderate (4), and Serious (70). two.5. Biomedical/Physiological Measurements Immediately after blood sample collection, blood pressure and body temperature had been measured. Systolic and diastolic blood pressure was measured even though the participant was lying down, using an aneroid sphygmomanometer. Body temperature was measured employing the tympanic strategy. Weight and height were measured having a calibrated digital scale using a stadiometer (Seca 264, Hamburg, Germany), together with the subjects standing upright with their heads inside the Frankfort plane based on the standards of
