METHODS: Postmenopausal breast cancer patients on endocrine therapy were recruited at three hospitals in Malaysia. Presence and severity of menopausal symptoms were determined using the Menopause Rating Scale. Sociodemographic and clinical data were collected from medical records.
RESULTS: A total of 192 patients participated in this study. Commonly reported symptoms were musculoskeletal pain (59.9%), physical and mental exhaustion (59.4%), and hot flushes (41.1%). Multivariate analyses indicated that increasing number of years after menopause until the start of endocrine therapy was significantly associated with less likelihood of reporting menopausal symptoms and musculoskeletal pain. Patients with primary or secondary education levels reported significantly less menopausal urogenital symptoms compared to patients with a tertiary education level. Patients using aromatase inhibitors were twice as likely to experience musculoskeletal pain compared to patients using tamoxifen (odds ratio, 2.18; 95% confidence interval, 1.06-4.50; p
OBJECTIVE: The present study aims to examine differences in psychological factors, disability and subjective fatigue between subgroups of LBP based on their chronification grade.
METHODS: Twenty-one healthy controls (HC) and 54 LBP patients (categorized based on the grades of chronicity into recurrent LBP (RLBP), non-continuous chronic LBP (CLBP), or continuous (CLBP)) filled out a set of self-reporting questionnaires.
RESULTS: The Hospital Anxiety and Depression Scale (HADS) and Multidimensional Pain Inventory (MPI) scores indicated that anxiety, pain severity, pain interference and affective distress were lower in HC and RLBP compared to non-continuous CLBP. Anxiety scores were higher in non-continuous CLBP compared to RLBP, continuous CLBP and HC. The Pain Catastrophizing Scale for Helplessness (PSCH) was higher in non-continuous CLBP compared to HC. The Survey of Pain Attitudes (SOPA) showed no differences in adaptive and maladaptive behaviors across the groups. The Pain Disability Index (PDI) measured a higher disability in both CLBP groups compared to HC. Moreover, the Rolland Morris Disability Questionnaire (RMDQ) showed higher levels of disability in continuous CLBP compared to non-continuous CLBP, RLBP and HC. The Checklist Individual Strength (CIS) revealed that patients with non-continuous CLBP were affected to a higher extent by severe fatigue compared to continuous CLBP, RLBP and HC (subjective fatigue, concentration and physical activity). For all tests, a significance level of 0.05 was used.
CONCLUSIONS: RLBP patients are more disabled than HC, but have a tendency towards a general positive psychological state of mind. Non-continuous CLBP patients would most likely present a negative psychological mindset, become more disabled and have prolonged fatigue complaints. Finally, the continuous CLBP patients are characterized by more negative attitudes and believes on pain, enhanced disability and interference of pain in their daily lives.
OBJECTIVES: To evaluate fatigue, identify factors associated with fatigue and assess the effect of fatigue on health-related quality of life (HRQoL) in a multi-ethnic cohort of RA patients.
METHODS: A cross-sectional study was performed in patients who fulfilled European League Against Rheumatism/ American College of Rheumatology 2010 criteria for RA. Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) questionnaire was used to assess fatigue. Potential factors for fatigue were categorized into RA-related (gender, seropositivity [rheumatoid factor and/or anti-citrullinated protein antibody], disease duration, visual analog scale pain score, Disease Activity Score of 28 joints - erythrocyte sedimentation rate [DAS28-ESR], ESR, hemoglobin level, functional disability [Health Assessment Questionnaire - Disability Index, HAQ-DI score], EQ-5D-3L, concomitant prednisolone use and number of conventional synthetic disease-modifying anti-rheumatic drugs [csDMARDs] used) and non-RA-related (age, body mass index, ethnicity and number of co-morbidities).
RESULTS: A total of 214 patients (86.9% female) were included; the median age was 62 (25-91) years and 67.3% were seropositive. Seventy-six (33.5%) patients had moderate disease activity, 12 (5.6%) had high disease activity and 152 (71%) patients had mild difficulties to moderate disability HAQ-DI scores. Median of total FACIT-F score was 113.2 (36.3-160.0). Joint factors of younger age, longer disease duration, higher HAQ score (increased functional disability), and lower EQ-5D (poorer HRQoL) were significantly associated with higher levels of fatigue (all P
METHODS: Twenty male participants performed repetitive submaximal (60% MVIC) grip muscle contractions to induce muscle fatigue and the results were analyzed during the pre- and post-fatigue MVIC. MMG signals were recorded on the extensor digitorum (ED), extensor carpi radialis longus (ECRL), flexor digitorum superficialis (FDS) and flexor carpi radialis (FCR) muscles. The cross-correlation coefficient was used to quantify the cross-talk values in forearm muscle pairs (MP1, MP2, MP3, MP4, MP5 and MP6). In addition, the MMG RMS and MMG MPF were calculated to determine force production and muscle fatigue level, respectively.
RESULTS: The fatigue effect significantly increased the cross-talk values in forearm muscle pairs except for MP2 and MP6. While the MMG RMS and MMG MPF significantly decreased (p<0.05) based on the examination of the mean differences from pre- and post-fatigue MVIC.
CONCLUSION: The presented results can be used as a reference for further investigation of cross-talk on the fatigue assessment of extensor and flexor muscles' mechanic.
PURPOSE: This study aimed to compare the kinetics of power output using FI and FR of an anaerobic performance (Wingate test) under 2, 3 and 4% state of hypohydrations.
METHOD: Thirty two collegiate cyclists (age = 22 ± 2 years; body weight = 71.45 ± 3.43 kg; height = 173.23 ± 0.04 cm) were matched using their baseline anaerobic peak power (APP) then randomly divided into 4 groups of EU (euhydrated), 2H, 3H and 4H respectively.
RESULTS: As expected the, FI, APP, anaerobic lower power (ALP) and rating of perceived exertion (RPE) did not show significant differences between and within the groups. However, the FR in 3H (0.018 ± 0.005 s(-1)) and 4H (0.019 ± 0.010 s(-1)) were significantly lower than EU (0.033 ± 0.012 s(-1)). Post-test FR also showed significant reduction in 3H and 4H compared to their pre-test values (p<0.05).
CONCLUSION: Despite the lack of changes in APP and RPE, subjects in 3H and 4H showed evidence of lower reduction of power output over time. The findings support earlier reports which showed no change in anaerobic performance under mild hypohydrations. The relatively lower FR suggests higher drive in maintaining power output under hypohydrations of 3 and 4% body weight.
