have been drawn by a health-related qualified into EDTA and serum tubes (Becton Dickinson) by way of antecubital venipuncture. Completed questionnaires were also collected on this day. In a follow-up inquiry by way of an electronic type where participants could indicate extra than one selection, info was gathered in regards to the reason why the participants were making use of a COC at the time. We received 20 out of 24 responses which had been as follows: Contraception, 12/20; Period regulation, 12/20; Acne treatment, 7/20; Menstrual cramp remedy, 6/20; Polycystic ovary syndrome (PCOS) therapy, 3/20; Endometriosis therapy, 1/20; Other, 1/20. 2.two. Dietary Evaluation The food frequency questionnaire was set up by a study dietician in the Centre of Excellence for Nutrition, North-West University, Potchefstroom Campus. The food frequency questionnaire was developed specifically to involve foods that could have an effect on biotransformation, by consulting the literature. The questionnaire will not be quantified and only the frequency of intake in the week prior to the test was assessed. The frequency per week was converted to an Caspase 1 Chemical Formulation typical frequency per day for statistical analysis. The questionnaire was self-administered by the participants. 2.three. Healthcare Symptoms Questionnaire An openly accessible Medical Symptoms Questionnaire (MSQ, File S1 included within the Supplementary Material on the web) in the Departments of Medicine, Mercy Hospital and Maine Healthcare Center, Portland [31] was completed by every single participant. The MSQ includes 19 domains, most with four items, totaling 75 indicators to each of which the patient assigns a Likert scale numerical ranking (0 becoming “never” or “seldom” and four CXCR4 Antagonist Purity & Documentation getting “frequently with severe effect”). The 75 concerns are divided into 15 main sections. The scores wereInt. J. Environ. Res. Public Wellness 2021, 18,4 ofcalculated as the imply of the items per section plus the products had been also combined in an general MSQ score. The reliability (Cronbach’s alpha worth) with the questionnaire had been confirmed previously to get a South African Caucasian population [30]. 2.4. Piper Fatigue Scale Assessment Every single participant also completed an English version from the revised Piper Fatigue Scale [32] (PFS, File S2 included within the Supplementary Material on the web). The revised PFS utilised consisted of 22 numerical products which assessed fatigue seasoned by the patients. All items have been coded on a 00 numeric scale. The revised PFS measured four dimensions of subjective fatigue: behavior/severity, affective which means, sensory, and cognitive/mood. The reliability (Cronbach’s alpha worth) in the questionnaire had been confirmed previously to get a South African Caucasian population [30]. To calculate a total fatigue score, the cumulative sum of all was divided by the total quantity of items. In accordance with the scoring guidelines in the PFS, the severity from the fatigue is often classified according to the following severity codes: None (0), Mild (1), Moderate (4), and Serious (70). 2.five. Biomedical/Physiological Measurements Right after blood sample collection, blood pressure and physique temperature had been measured. Systolic and diastolic blood stress was measured even though the participant was lying down, applying an aneroid sphygmomanometer. Physique temperature was measured utilizing the tympanic system. Weight and height were measured with a calibrated digital scale using a stadiometer (Seca 264, Hamburg, Germany), with the subjects standing upright with their heads within the Frankfort plane in line with the standards of
