Frequency, severity and distress of dialysis-related symptoms reported by patients on hemodialysis

Purpose. To determine which symptoms are the most reported, occur most frequently, have the greatest severity, and cause the most bother for hemodialysis (HD) patients and to determine if the symptoms experienced differ between the first (HD 1) and second (HD 2) treatments of the week. ^ Design. An observational, comparative design was used to determine participants' HD symptoms experience on HD 1 and HD 2, and the effect of the symptom experience on Quality of Life (QOL). One hundred subjects were recruited from five dialysis centers. ^ Methods. The adapted Dialysis Frequency, Severity and Symptom Burden Index (DFSSBI) and the Medical Outcomes Study Short Form 36 (MOS SF 36) were administered (N = 99) on HD 1 and the DFSSBI again on HD 2. Data were analyzed for significance among symptoms experience test scores in relation to HD 1 and HD 2, QOL, and gender and age. ^ Results. Of 31 symptoms assessed, respondents reported an average of 9.69 symptoms on HD 1 and 7.51 symptoms on HD 2. Overall, more symptoms were reported, and were more frequent, severe and bothersome on HD 1 when the level of metabolic waste is highest. The most reported symptoms included tiredness, dry skin, difficulty falling asleep, itching, numbness/tingling, difficulty staying asleep, decreased interest in sex, and bone/joint pain. Females scored consistently higher than males in the four symptom dimensions. The respondents reported about the same as the population norm (50) on the physical component summary score of the MOS SF 36 and higher than the norm (65.23) on the mental component summary score. ^ Conclusion. The study findings highlighted the fact that hemodialysis patients experience multiple symptoms that can be frequent, severe, and bothersome. Interventions should be developed and tested to reduce symptom burden and improve QOL. ^

Ethnic differences in adolescents' mental distress

Objectives. The aims of this cross-sectional study were to (1) examine differences among four ethnic groups of middle school students (Anglos, African Americans [AAs], Hispanics, and Asians) on (a) three indicators of mental distress (depression, somatic symptoms, suicidal ideation) (b) social stress (general social stress, process-oriented stress, discrimination) and resources (family relationships, coping, self-esteem) and (2) identify significant risk factors and resources for each ethnic group by examining the moderating effects of ethnicity. ^ Methods. Respondents included 316 students from three schools (144 Anglos, 66 AAs, 77 Hispanics, 29 Asians/Others) who completed self-administered questionnaires. Social stress and somatic symptoms were measured by using the SAFE-C and Somatic Symptom Scale, respectively. The DSD was used to assess depression and suicidal ideation. Resources were measured by using the FES, age-appropriate adaptations of two existing coping scales, and Rosenberg's Self-Esteem Scale. For specific aims, descriptive statistics, ANOVA, ANCOVA, and logistic regression analysis were used. ^ Findings. No statistically significant ethnic group or gender differences were observed in depression and somatic symptoms, but the odds of experiencing depression symptoms were about 9.7 times greater for Hispanic females than for the referent group, Anglo males. Hispanics were also 2.04 times more likely to have suicidal ideation than Anglos ( P < 0.05). AAs and Hispanics reported significantly higher levels of stress than Anglos (OR: 2.2–4.3, 0.00 ≤ P ≤ 0.03). These findings imply that adolescents in these ethnic groups may be exposed to considerable amounts of stress even if they do not exhibit significant symptoms of mental distress yet. Negative moderating effects for ethnicity were found by the significant interaction between ethnicity and social stress in somatic symptoms among AAs and Hispanics. This finding indicates that AA and Hispanic adolescents may require higher levels of social stress to exhibit the same amount of somatic symptoms as Anglo adolescents. Observed ethnic differences in social stress and interaction between social stress and ethnicity in relation to somatic symptoms demonstrated a need for subsequent longitudinal studies, and provided a rationale for incorporating social stress as a critical component not only in research but also in culturally sensitive prevention programs. ^
