“…A higher score indicates a higher level of functioning. Additionally, the shortlist of the Dutch validated checklist individual strength (CIS)-fatigue, consisting of eight questions scored on a 7-point Likert scale (24), was used. The range of the CIS-fatigue is 8 to 56, a higher score indicating more pronounced fatigue.…”

“…Chronic fatigue patients were assigned to the CFS or CFI group according to the criteria of Fukuda [ 1 ]. Operational criteria for assignment were: a score of >40 on the fatigue subscale of the Checklist Individual Strength (CIS-20) [ 11 ], score of?≤?35 for vitality, ≤ 62.5 for Social Functioning and ≤50 for Role-Physical on the SF-36 [ 12 ] and ≥4 positive scores (≥7,5) of the additional symptoms of the CDC Symptom Inventory –DLV [ 13 ] for the diagnosis of CFS and ≤4 positive scores (≥7,5) of the additional symptoms of the CDC Symptom Inventory –DLV for the diagnosis of idiopathic chronic fatigue (CFI) . The cognitive function of patients was screened with the Shifting Attentional Test Visual of the Amsterdam Neuropsychological Tasks [ 14 ].…”

BackgroundThe insufficient metabolic adaptation to exercise in Chronic Fatigue Syndrome (CFS) is still being debated and poorly understood.MethodsWe analysed the cardiopulmonary exercise tests of CFS patients, idiopathic chronic fatigue (CFI) patients and healthy visitors. Continuous non-invasive measurement of the cardiac output by Nexfin® (BMEYE B.V. Amsterdam, the Netherlands) was added to the cardiopulmonary exercise tests. The peak oxygen extraction by muscle cells and the increase of cardiac output relative to the increase of oxygen uptake (ΔQ’/ΔV’O2) were measured, calculated from the cardiac output and the oxygen uptake during incremental exercise.ResultsThe peak oxygen extraction by muscle cells was 10.83 ± 2.80 ml/100ml in 178 CFS women, 11.62 ± 2.90 ml/100 ml in 172 CFI, and 13.45 ± 2.72 ml/100 ml in 11 healthy women (ANOVA: P=0.001), 13.66 ± 3.31 ml/100 ml in 25 CFS men, 14.63 ± 4.38 ml/100 ml in 51 CFI, and 19.52 ± 6.53 ml/100 ml in 7 healthy men (ANOVA: P=0.008).The ΔQ’/ΔV’O2 was > 6 L/L (normal ΔQ’/ΔV’O2 ≈ 5 L/L) in 70% of the patients and in 22% of the healthy group.ConclusionLow oxygen uptake by muscle cells causes exercise intolerance in a majority of CFS patients, indicating insufficient metabolic adaptation to incremental exercise. The high increase of the cardiac output relative to the increase of oxygen uptake argues against deconditioning as a cause for physical impairment in these patients.

Long-Term Health Related Quality of Life following Intensive Care during Treatment for Haematological Malignancies

et al. 2014

ObjectiveLong-term health-related quality of life (HRQoL) was determined for patients admitted to the haematology ward who needed intensive care treatment (H-IC+) and compared with those who did not (H-IC−) as well as with that for patients admitted to the general ICU (nH-IC+).MethodsA cross-sectional study was carried out median 18 months after admission by employing the short form-36, checklist for individual strength, cognitive failure questionnaire and hospital anxiety and depression scale.Results27 (79%) of the 34 H-IC+ patients approached, and 93 (85%) of the 109 H-IC− patients approached replied. Data were adjusted for relevant covariates and matched with those of 149 patients in the general ICU. Apart from the lower role-physical functioning score for H-IC+ (P = 0.04) no other differences were found between H-IC+ and H-IC−. Groups H-IC+ and nH-IC+ evaluated their HRQoL on SF-36 similarly, except for the lower aggregated physical component summary (PCS) for H-IC+ (P<0.0001). After adjusting for PCS, no significant differences in CIS, CFQ and HADS were observed between the groups.ConclusionsEighteen months after admission, patients treated for haematological malignancies reported similar HRQoL, whether or not they had received intensive care treatment, but reported a lower PCS than those of patients in the general ICU. Hence, there is no reason to assume that admission to the ICU has a negative impact on long-term HRQoL, so this should not affect the decision whether or not to transfer patients with haematological malignancies to the ICU.
