“…The Multidimensional Fatigue Inventory (MFI-20) is a 20-item self-report instrument consisting of 5 subscales: 1) general fatigue, 2) physical fatigue, 3) reduced activity, 4) reduced motivation, and 5) mental fatigue. 21 , 22 Each subscale consists of 4 items with possible answers on a 5-point Likert scale (1 = yes, that is true; 5 = no, this is not true). Higher scores indicate higher levels of fatigue.…”

Purpose: In this cross-sectional survey, we assessed the prevalence of dry eye disease (DED) in a representative German population sample. In addition, we examined the associations between DED, health-related quality of life (HRQoL), and level of fatigue. Finally, we further validated the German version of the Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire and present norm data of the German population. Methods: A random sample of German residents aged 16 years and older was recruited between October and December 2021. All participants completed the SPEED, Short Form 36, and Multidimensional Fatigue Inventory 20 questionnaires. Results: Of the 2495 participants who completed the survey, 450 (21.6%; 95% confidence intervals 20.0–23.1) reported a SPEED total score of ≥4, indicating a positive screening for DED. DED was significantly more common in women and older age. Participants who screened positive for DED reported significantly higher levels of fatigue and lower values in all domains of HRQoL. A receiver operating characteristic curve of the SPEED was generated using an ophthalmologist's diagnosis. The area under the curve was estimated to be 0.886 (95% confidence intervals 0.858–0.913). A cutoff score ≥4 seemed to be appropriate as an indicator of DED. Cronbach's α was excellent (0.95). Conclusions: DED is common in the German population. We confirmed associations with sex, age, HRQoL, and fatigue level, indicating a high burden of DED. The German version of the SPEED is a valid instrument for the assessment of DED symptoms.

“…Fatigue syndrome was diagnosed at a score of ≥12 for any of the five scales of the MFI-20, and a higher score indicated a higher level of fatigue (severe), while a lower score indicated a lower level of fatigue. The MFI-20 was designed to prevent and minimize the influence of subjective factors on participants [20] and has demonstrated reliability in measuring fatigue in the general population [21].…”

Environmental hazards and/or pandemics may push humans to use different protective methods to maintain their well-being. This study aimed to identify populations vulnerable to psychometric challenges and fatigue during the Coronavirus Disease (COVID-19) pandemic in Kazakhstan. A total of 1,592 participants were recruited and asked to complete the Multidimensional Fatigue Inventory-20 (MFI-20). Participants were classified according to gender and age. Data were analyzed using the Chi-square test (x2) and MedCalc to detect the odds of MFI-scales with a score ≥12 in women compared to men. Young women had significantly higher odds (OR) of reduced activity (OR 2.4, p<0.0001), physical (OR 2.5, p<0.0001), and mental fatigue (OR 3.4, p<0.0001) than young men. Middle-aged women had significantly higher odds of general fatigue (OR 2.1; p<0.0001), reduced motivation (OR 2.1, p<0.0001), physical (OR 2.1, p<0.0001), and mental fatigue (OR 1.9, p<0.0001) than did middle-aged men. Elderly women had significantly higher odds of general fatigue (OR 3.6, p<0.0001), reduced motivation (OR 3.5, p<0.0001), and physical fatigue (OR 3.5, p<0.0001) than men in the same age category. The study highlights that women were more susceptible, with significantly increased odds of experiencing various aspects of fatigue syndrome compared to men during the COVID-19 pandemic in Kazakhstan. Therefore, it is necessary to investigate individual behavioral changes to help identify vulnerable populations and provide relevant evidence for developing protocols and guidelines during pandemics and/or outbreaks.

Introduction: Post-COVID-19 syndrome (PCS) is a multisystemic disorder marked by impaired physical performance as one lead symptom. Since it has been suggested that endurance training as part of medical rehabilitation may be effective in improving physical performance capacity in PCS, this study aimed to compare different modes of aerobic endurance training. Methods: A total of 110 PCS patients (49.3 ± 11.8 years; 38% women; time after infection = 260.2 ± 127.5 days) underwent detailed clinical screening including symptom-limited cardiopulmonary exercise testing at admission and after 4–6 weeks of inpatient medical rehabilitation. Questionnaires were used to assess disease perception. Patients performed controlled isocaloric cycle ergometer training (3–5 sessions/week; 18 min) as either continuous training (CT) at 50% of maximal workload or as interval training (IT; load = 60%, relief = 30%). Outcomes of PCS patients were compared to coronary artery disease patients (CAD; n = 96) to evaluate overall training effectiveness. Results: Training participation was comparable between the groups, with no indication of training-specific exercise-induced fatigue. Overall, PCS patients improved significantly by a mean of 6.8 ± 12.1% for W at VT1; 3.1 ± 10.0% for VO2 at VT1; 5.5 ± 14.7% for O2 pulse at VT1; 7.5 ± 15.0% for W at VO2peak; 2.7 ± 11.0% for VO2peak and 4.6 ± 12.4% for O2 pulse at VO2peak (all p < 0.05) with no significant differences between groups (p > 0.05). Both groups showed reduced levels of fatigue, anxiety, and depression as well as improved quality of life and wellbeing (all p < 0.05). Compared to guideline-based cardiac rehabilitation, PCS patients showed a similar improvement in workload and oxygen uptake compared to CAD patients. Conclusion: PCS patients benefit from aerobic endurance training performed as moderate continuous or interval training as part of a medical rehabilitation program in terms of improved physical exercise capacity and disease perception. The results for PCS patients are comparable to the guideline-based rehabilitation of CAD patients.
