Although enthusiasm for measuring health-related quality of life (HRQL) in clinical trials exists, information is limited on the meaning of scores. We examined the relation between scores from the 34-item Medical Outcomes Study HIV Health Survey (MOS-HIV) and the more detailed HIV Overview of Problems-Evaluation System (HOPES) using the responses of 318 HIV-infected outpatients being treated in Los Angeles and Baltimore. With the HOPES problem statements as independent variables, statistically significant predictors of the variation in MOS-HIV scores for the Physical Function, Mental Health, and Energy/Fatigue scales were identified using stepwise regression. Approximately 60% to 70% of the variation in each of the scores was explained by five to seven different HOPES problem statements, with a single item explaining 47% to 59% of the variation. We created illustrative profiles for each of the three MOS-HIV scales using the HOPES items identified in the regressions. Independent of the scale, persons scoring in the top MOS-HIV quartile tended to report few if any problems, whereas a decline in score to the next quartile was characterized by functional difficulties (e.g., "HIV interferes with work"). The onset of specific problems might trigger further evaluation and potential intervention from health care providers to help maintain patient functioning.

Associations between self-reported 'low iron', general health and well-being, vitality and tiredness in women, were examined using physical (PCS) and mental (MCS) component summary and vitality (VT) scores from the MOS short-form survey (SF-36). 14,762 young (18-23 years) and 14,072 mid-age (45-50 years) women, randomly selected from the national health insurance commission (Medicare) database, completed a baseline mailed self-report questionnaire and 12,328 mid-age women completed a follow-up questionnaire 2 years later. Young and mid-age women who reported (ever) having had 'low iron' reported significantly lower mean PCS, MCS and VT scores, and greater prevalence of 'constant tiredness' at baseline than women with no history of iron deficiency [Differences: young PCS = -2.2, MCS = -4.8, VT = -8.7; constant tiredness: 67% vs. 45%; mid-age PCS = -1.4, MCS = -3.1, VT = -5.9; constant tiredness: 63% vs. 48%]. After adjusting for number of children, chronic conditions, symptoms and sociodemographic variables, mean PCS, MCS and VT scores for mid-age women at follow-up were significantly lower for women who reported recent iron deficiency (in the last 2 years) than for women who reported past iron deficiency or no history of iron deficiency [Means: PCS--recent = 46.6, past = 47.8, never = 47.7; MCS--recent = 45.4, past = 46.9, never = 47.4; VT--recent = 54.8, past = 57.6, never = 58.6]. The adjusted mean change in PCS, MCS and VT scores between baseline and follow-up were also significantly lower among mid-age women who reported iron deficiency only in the last 2 years (i.e. recent iron deficiency) [Mean change: PCS = -3.2; MCS = -2.1; VT = -4.2]. The results suggest that iron deficiency is associated with decreased general health and well-being and increased fatigue.

Chronic back tiredness or fatigue is a common complaint of people who have a history of osteoporotic vertebral fracture. Trunk muscle endurance has not been studied in people with vertebral osteoporosis, partly due to the lack of assessment tools. We developed a measure of combined trunk and arm endurance suitable for people with vertebral osteoporosis, timed loaded standing (TLS). TLS measures the time a person can stand while holding a two-pound dumbbell in each hand with the arms at 90 degrees of shoulder flexion and the elbows extended. Intraclass correlation coefficients (ICCs) for same day inter-trial and six to ten day test-retest reliability were 0.89 (lower bound 95% confidence interval [LB 95% CI] 0.79) and 0.84 (LB 95% CI 0.68), respectively, in a sample of 21 older women with no known osteoporosis. In 127 women with vertebral fractures, the ICC for same day inter-trial reliability was 0.81 (LB 95% CI 0.75). In a sub-sample of 30 of these women with vertebral fractures, the six to ten day test-retest reliability was 0.85 (LB 95% CI 0.75). Moderately strong and statistically significant (p < or = 0.05) correlations were found between TLS and sixteen of eighteen measures of physical impairment and function. Functional reach distance, gait velocity, MOS-36 Physical Function Subscale, shoulder flexion strength, and six minute walk distance were most strongly associated with TLS time. Women with vertebral fractures who endorsed having back tiredness when standing and working with the arms in front of the body, sitting to rest because of back tiredness or pain, and planning rest periods because of back tiredness or pain had significantly lower TLS times. TLS is a simple, safe physical performance measure of combined trunk and arm endurance that demonstrates acceptable reliability (inter-trial and test- retest) and concurrent validity.

The purpose of this study was to compare the quality of life (QOL) of male and female allogeneic BMT recipients. One hundred and nine BMT patients participated in this cross-sectional survey and completed the following instruments: Functional Assessment of Cancer Treatment (FACT-BMT version 3), shortened version of Profile of Mood States (POMS), MOS Survey of Social Support, and A Brief Measure of Social Support (SSQ6). Independent of the time post-BMT, perceived physical well-being, age at BMT, and education, females reported worse emotional well-being and more fatigue than males. Females also indicated more tiredness and less quality sleep. Males were found to experience less satisfaction with social support regardless of marital status. On the other hand, married males were more satisfied with their sexual life, more interested in sexual relationships, and more sexually active compared to married females. However, no significant differences between males and females were found in terms of overall physical, functional, and social well-being assessed by the FACT-BMT. The present results indicated that important gender differences exist among allogeneic BMT recipients which need to be addressed when designing post-treatment intervention programs for BMT recipients.

We investigated the clinical activity of the farnesyl transferase inhibitor R115777 in 22 patients with chronic myelogenous leukemia (CML) in chronic, accelerated, or blastic phase and in 8 patients with myelofibrosis (MF) and 10 patients with multiple myeloma (MM). R115777 was administered at 600 mg orally twice daily for 4 weeks every 6 weeks. Seven patients with CML (6 in chronic phase, 1 in advanced phase) achieved complete or partial hematologic response. Four of them had a minor cytogenetic response. Responses were transient, with a median duration of 9 weeks (range, 3-23 weeks). Two patients discontinued therapy because of toxicity while in complete hematologic response. Two MF patients had a significant decrease in splenomegaly, one had normalization of white blood cell count and differential, and one became transfusion independent. One patient with MM had a reduction in monoclonal protein of 34%. Adverse events included nausea in 22 patients (55%; all grade 2 or lower) and fatigue in 19 (48%; grade 3 or higher in 1). Other grade 3 or 4 toxicities included skin rash (4 patients, 10%), peripheral neuropathy (2 patients, 5%), and liver toxicity (2 patients, 5%). Patients who responded to therapy had significantly higher plasma vascular endothelial growth factor (VEGF) concentrations prior to treatment than nonresponders. Plasma concentrations decreased significantly during therapy among responders. R115777 showed clinical activity in patients with CML and MF. The effect on VEGF needs to be further investigated to determine whether this might be a possible mechanism of action of R115777.

Early disability and its rapid progression emphasize the medico-social importance of MS. The widely used disease-modifying treatments allowed to delay the time of severe disability, but this way of treatment is very expensive. The cost of MS is discussed based on literature data. The level of the cost of MS greatly depends on the disease severity and activity. Thus the studies of quality of life (QL) and pharmacoeconomical analysis, besides neurological scales, can give important additional information for clinical trials. First such studies in Europe in patients with secondary progressive MS showed a delay in progression of QL indexes in patients under Betaferon treatment in comparison to placebo. We studied changes in MOS SF-36 and WHO QL scales in groups of 60 MS patients, receiving Rebif or Copaxone. After 3 months of Rebif significant positive changes in scales, reflecting physical and social activity of MS patients, were found. At the same time negative changes in the "Pain" scale might reflect the presence of local side effects of beta-interferons treatment. No statistically significant changes in QL indexes under treatment with Copaxone were seen. The results of QL testing were associated with data of neuropsychological tests, characterizing chronic fatigue and depression. Thus the measurement of QL indexes may be a source of significant additional information, estimating the effecis of treatment and is the basic for pharmacoeconomical analysis.

A growing body of evidence is documenting the multidimensional nature of cancer-related fatigue. Although several multidimensional measures of fatigue have been developed, further validation of these scales is needed. To this end, the current study sought to evaluate the factorial and construct validity of the 30-item Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF). A heterogeneous sample of 304 cancer patients (mean age 55 years) completed the MFSI-SF, along with several other measures of psychosocial functioning including the MOS-SF-36 and Fatigue Symptom Inventory, following the fourth cycle of chemotherapy treatment. The results of a confirmatory factor analysis indicated the 5-factor model provided a good fit to the data as evidenced by commonly used goodness of fit indices (CFI 0.90 and IFI 0.90). Additional evidence for the validity of the MFSI-SF was provided via correlations with other relevant instruments (range -0.21 to 0.82). In sum, the current study provides support for the MFSI-SF as a valuable tool for the multidimensional assessment of cancer-related fatigue.

Routine clinical assessment of health-related quality of life in persons with HIV infection has the potential to improve care by assessing and monitoring treatment effects, enhancing communication between patient and provider, and tracking changes in functional status over time. Currently available research-based assessment tools may be inadequate for routine clinical use because of the lack of inclusion of HIV-relevant aspects of quality of life and the impracticality of the use of such tools in the clinical setting. There may be a need for a new, clinically relevant, HIV-specific assessment tool that would be easy to incorporate into clinical practice to briefly, yet comprehensively, assess characteristics frequently found in HIV-infected persons, such as fatigue, pain, nausea and vomiting, sleep disturbances, sexual dysfunction, and body image issues. Until such a tool is developed, the Linear Analogue Self-Assessment questionnaire and the Medical Outcomes Study Short Form-12 (MOS SF-12) are short enough for routine use in a clinical setting. Slightly longer measures, such as the MOS-HIV Health Survey (MOS-HIV), can provide information in a greater number of domains.

A cross-sectional study was conducted among 249 Chinese cancer patients with multiple diagnoses to validate a Chinese version of the Brief Fatigue Inventory (BFI-C). Cronbach's coefficient alpha was 0.92 for fatigue severity items and 0.90 for fatigue interference items. Construct validity was explored by principal factor analysis and suggested a two-factor solution: fatigue severity and fatigue interference. Internal consistency reliability was excellent. Convergent validity was examined by correlating the BFI-C with 2 subscales and 2 component scores of the MOS 36-Item Short-Form Health Survey (coefficients ranged between -0.44 and -0.71, P<0.001). Known-group validity was examined by comparing fatigue severity in patients having different scores on the Eastern Cooperative Oncology Group Performance Status Scale. Approximately 60% of patients experienced moderate to severe fatigue (4 or greater on the 0-10 scale of the BFI-C "fatigue worst" item). The BFI-C is a valid, reliable instrument to measure the severity and impact of cancer-related fatigue among Chinese patients.

We report on a young female who had presented with fatigue, bilateral knee pain and gait disturbance. Primary hyperparathyroidism was diagnosed together with splenomegaly and anemia. Bone marrow biopsy revealed myelofibrosis. A parathyroid adenoma was excised during surgical intervention. As early as three months after the operation, hematologic parameters improved along with bone markers without any other intervention. The control bone marrow biopsy demonstrated well marked regression in marrow fibrosis. Her spleen has also gradually decreased in size. These findings indicate that her myelofibrosis was the result of primary hyperparathyroidism. Anemia associated with primary hyperparathyroidism may be due to bone marrow fibrosis.
