Classification of myalgic encephalomyelitis/chronic fatigue syndrome by types of fatigue.

Persons with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) often complain of fatigue states (eg, postexertional malaise, brain fog) that are qualitatively different than normal, daily fatigue. Given the heterogeneous nature of ME/CFS, it is likely that individuals with this illness experience these fatigue types differently in terms of severity and frequency. It is also possible that meaningful subgroups of patients exist that exhibit different patterns of the fatigue experience. The purpose of this study was to investigate whether individuals with ME/CFS can be classified in a meaningful way according to the different types of fatigue they experience. One hundred individuals with ME/CFS participated in the study. Individuals that met inclusion criteria were administered the Multiple Fatigue Types Questionnaire (MFTQ), a 5-factor instrument that distinguishes between different types of fatigue. A cluster analysis was used to classify patients into various clusters based on factor subscale scores. Using a 3-factor solution, individuals were classified according to illness severity (low, moderate, severe) across the different fatigue factors. However, a 5-cluster solution enabled participants with moderate to severe fatigue levels to fall into more differentiated clusters and demonstrate distinct fatigue state patterns. These results suggest that fatigue patterns of individuals with ME/CFS are heterogeneous, and that patients may be classified into meaningful subgroups.

Low serum ferritin and G6PD deficiency as potential predictors of anaemia in pregnant women visiting Prime Care Hospital Enugu Nigeria.

OBJECTIVES: Though iron deficiency is known to be a major risk factor of anaemia, the association of G6PD deficiency and malaria with anaemia still remains unclear. Hence, a cross-sectional study involving 95 pregnant women visiting Prime Care Hospital in Trans-Ekulu region of Enugu Nigeria was conducted to determine possible predictors of anaemia in pregnancy. RESULTS: The prevalence of anaemia, malaria and G6PD deficiency were 53.7, 12.6 and 60% respectively. Low serum ferritin (OR 5.500, CI 2.25-13.42, p < 0.05) and G6PD deficiency (OR 0.087, CI 0.03-0.23, p < 0.05) were associated with anaemia in pregnancy. On the other hand, malaria did not significantly associate (OR 1.184, CI 0.35-3.97, p = 0.964) with anaemia in pregnant women. These findings showed high prevalence of anaemia among pregnant women with low serum ferritin level and G6PD deficiency as high risk factors of anaemia.

The relationships among coping styles and fatigue in an ethnically diverse sample.

The present study focused on coping strategies among African Americans, Latinos, and European Americans with chronic fatigue syndrome (CFS) and idiopathic chronic fatigue (ICF). The coping strategies examined were measured by using the COPE Scales, which assess Seeking Emotional Social Support, Positive Reinterpretation and Growth, Acceptance, Denial, Turning to Religion, Behavioral Disengagement, and Focusing on and Venting Emotions. In addition, the four coping strategies specifically designed for people with CFS, including maintaining activity, accommodating to the illness, focusing on symptoms, and information-seeking, were used in this study. It was hypothesized that African Americans and Latinos in comparison to European Americans would be more likely to use religious coping, behavioral disengagement, and denial. As predicted, African Americans were significantly more likely to turn to religion than European Americans, and Latinos and African Americans used denial significantly more often than European Americans. An additional finding was that focusing on symptoms was associated with greater fatigue and more physical disability among African Americans. Within the Latino sample, acceptance was related to greater fatigue and less physical disability, and greater optimism predicted less mental disability. Among European American participants, maintaining activity was related to less mental disability, whereas accommodating to the illness predicted more physical disability. These results indicate that coping varies among various ethnic groups with CFS and ICF; however, denial is consistently related to less adaptive outcomes. Therefore, healthcare professionals should find ways to reduce patient use of denial and promote alternative strategies for managing life events.
