The impact of inpatient neurorehabilitation on psychological well-being on discharge and at 3 month follow-up.

INTRODUCTION: Neurological rehabilitation aims to improve quality of life of patients with acute and chronic neurological conditions. Much of the existing research focuses on the impact of rehabilitation on physical functioning, with less emphasis on emotional wellbeing. This study assessed changes in psychological functioning in patients on discharge from rehabilitation and three months after discharge. METHODS: Patients admitted over a six-month period to a neurological rehabilitation unit were recruited prospectively to this study. Psychological functioning was measured by the self-report General Health Questionnaire and the Hospital Anxiety and Depression Scale. In addition, physical functioning was measured by the Barthel index and Functional Independence Measure. RESULTS: Psychological functioning was found to be significantly improved with rehabilitation. However, after three months, patients' scores returned to pre-treatment values. Anxiety was consistently elevated on admission, discharge and follow-up. In contrast, physical functioning improved from admission to discharge and was maintained at follow-up assessment. CONCLUSION: Rehabilitation services need to focus more on psychological functioning after discharge and identify effective strategies to maintain wellbeing.

The role of cognitive ability (intelligence) in explaining the association between socioeconomic position and health: evidence from the Whitehall II prospective cohort study.

Associations among cognitive ability, socioeconomic position, and health have been interpreted to imply that cognitive ability could explain social inequalities in health. The authors test this hypothesis by examining three questions: Is cognitive ability related to health? To what extent does it explain social inequalities in health? Do measures of socioeconomic position and cognitive ability have independent associations with health? Relative indices of inequality were used to estimate associations, using data from the Whitehall II study (baseline, 1985-1988), a British prospective cohort study (4,158 men and 1,680 women). Cognitive ability was significantly related to coronary heart disease, physical functioning, and self-rated health in both sexes and additionally to mental functioning in men. It explained some of the relation between socioeconomic position and health: 17% for coronary heart disease, 33% for physical functioning, 12% for mental functioning, and 39% for self-rated health. In analysis simultaneously adjusted for all measures of socioeconomic position, cognitive ability retained an independent association only with physical functioning in women. These results suggest that, although cognitive ability is related to health, it does not explain social inequalities in health.

Evaluating task modification as an objective measure of functional limitation: repeatability and comparability.

BACKGROUND: Modification of everyday tasks in older adults is associated with risk of deleterious health outcomes. The purpose of this study was to develop a task modification scale to examine its reliability and comparability to timed performance and common measures of physical function and impairment. METHODS: Eighty-two (21 men, 61 women) older adults (74.4 +/- 8.2 years) were observed performing a chair rise (sitting heights: 43 cm, 38 cm, and 30 cm), stair ascent/descent, and kneel and supine rise tasks. Six hierarchically ranked categories (0-5) of modification were created for each task and then summed across tasks (summary modification [MOD] score: range 0-35). Comparisons were made with timed performance, knee extension strength, single-leg balance, self-reported function, five chair stands, and gait speed. RESULTS: Inter-rater reliability (intra-class correlation = 0.98) and participant repeatability (intra-class correlation = 0.92) of the MOD score were excellent. Ninety-six percent of participants modified at least one task (MOD score: 10.5 +/- 7.51, range 0-27). After adjusting for task modification, timed performance showed a lower association with gait speed (time vs MOD score, semipartial r2 = 0.31 vs 0.68), strength (semipartial r2 = 0.14 vs 0.65), and single-leg balance (semipartial r2 = 0.10 vs 0.40) than did the MOD score. The MOD score showed higher correlations with muscle strength and balance impairment than did other measures of functional limitation such as gait speed, time to complete five chair stands, and self-reported physical function. CONCLUSION: Documentation of task modification is reliable across raters and repeatable within participants; in addition, it compares well with other measures of physical function and impairment. Task modification reveals important and intuitive information regarding physical limitation, and deserves greater attention.

Stage of regular exercise and health-related quality of life.

BACKGROUND: Research on cognitive factors and motivational readiness for exercise is important for increasing our understanding of behavior change among those with sedentary lifestyles. This study examines stage of change for regular exercise and self-perceived quality of life. METHODS: Data are from 1,387 respondents to a random digit dial survey of health behaviors. Stage of change is assessed with a single item, and individuals are classified with respect to intention and exercise behavior. Quality of life is assessed with the SF-36, a multidimensional measure of health-related quality of life. RESULTS: Exercise stage is associated with self-perceived quality of life. The three areas most strongly related were physical functioning, general health perceptions, and vitality. Physical functioning scores were lowest in precontemplation and highest in maintenance. Vitality and mental health scales were related to exercise behavior, but not to intention. CONCLUSIONS: Cognitions about self-perceived quality of life vary across the stages of change, with those who are least prepared to adopt regular exercise reporting the lowest levels of quality of life. These findings suggest that cognitive-motivational messages designed to emphasize quality of life benefits associated with exercise may be useful intervention strategies for people who are less motivationally ready to change.

Exercise rehabilitation of older patients with cardiovascular disease.

As the population of elderly patients with cardiovascular disease continues to increase, much research needs to be done with the goal of maintaining physical functioning and personal independence in this population. It is of particular importance to determine whether training programs can improve physical functioning in the most severely disabled older coronary patients. Effects of cardiac rehabilitation programs on other outcome measures, including psychosocial outcomes, lipid levels, insulin levels, and body composition require better study. Finally, the economic benefits of cardiac rehabilitation in the older coronary patients has received little attention, although early reports are promising. In summary, the older population with coronary disease is characterized by high rates of disability. Exercise training has been demonstrated to be safe and to improve strength, aerobic fitness capacity, endurance and physical function. It remains to be seen whether exercise training can reverse or prevent disability in a broad population of older patients with cardiovascular disease. If successful, cardiac rehabilitation programs will pay great medical, social, and economic dividends in this population.

Sex differences in claudication pain in subjects with peripheral arterial disease.

PURPOSES: To compare the claudication distances between men and women patients with peripheral arterial disease (PAD), and to determine whether sex differences in claudication pain persisted after controlling for potential confounders such as demographic, functional, and physiological measures. METHODS: A total of 488 men and 72 women functionally limited by intermittent claudication were evaluated. Patients were characterized on PAD-specific measures consisting of ankle/brachial index (ABI) and treadmill claudication distances, physical function measures consisting of ambulatory function, monitored physical activity, balance, and strength, and demographic measures obtained during a medical history. RESULTS: Initial claudication distance (ICD) was 33% shorter ( = 0.024) in women than in men (126 +/- 22 vs 189 +/- 13 m; mean +/- SEM), and absolute claudication distance (ACD) was 23% shorter ( = 0.022) in women (313 +/- 43 vs 407 +/- 18 m). These differences were present despite similar ( = 0.440) ABI values between women (0.63 +/- 0.02) and men (0.62 +/- 0.01). Peak oxygen uptake ( = 0.043) and self-perceived stair climbing ability ( = 0.020) were different between men and women, and were independently related to ICD (multiple R = 0.57, < 0.001) and to ACD (multiple R = 0.71, < 0.001). The sex differences in ICD ( = 0.524) and ACD ( = 0.722) were no longer present after controlling for peak oxygen uptake and self-perceived stair climbing ability. CONCLUSION: Shorter treadmill claudication distances in women with PAD were explained by their lower cardiopulmonary fitness and poorer self-perceived ability to climb stairs than compared with men. Therefore, women with intermittent claudication represent a subgroup of PAD patients who should receive high priority for exercise rehabilitation to improve physical function.

Health outcome assessment before and after lumbar laminectomy for radiculopathy.

STUDY DESIGN: Forty-one patients undergoing lumbar laminectomy for radiculopathy resulting from herniated discs assessed their health status using a generic health outcome instrument (Medical Outcomes Study Short Form 36) before surgery and at an average of 2 years after surgery. OBJECTIVES: To assess whether lumbar laminectomy for herniated nucleus pulposus is a useful intervention when patients evaluate their own perception of health. SUMMARY OF BACKGROUND DATA: The medical Outcomes Study Short Form 36 has been used in multiple studies assessing various medical conditions. It is brief, generic, and reliable. Although surgical treatment for radiculopathy by lumbar laminectomy has been shown to be successful using specific criteria for patient selection and an algorithmic approach, the authors are not aware of any study using a patient-based health outcome assessment to evaluate the results of this type of surgery. METHODS: Forty-one patients (82% completed follow-up evaluation; average follow-up period, 2.08 years) completed Medical Outcomes Study Short Form 36 before and after surgery. Scores from before and after surgery were compared. RESULTS: Statistically significant improvements (P < 0.01) were seen in eight of the nine health scores comparing scores from before and after surgery at follow-up evaluation. These included physical function, social function, role function resulting from physical limitations, role function resulting from emotional limitations, mental health, vitality, pain, and perceived health change. No significant change was seen in the patients' health perception after surgery. CONCLUSIONS: This study shows that the patients' self-reported health outcomes after lumbar laminectomy correlate with the excellent results previously seen using physician-driven outcome measures in an appropriately selected population with radiculopathy. The excellent results shown here did not deteriorate with age (> 40 years compared with < 40 years) or with complications after surgery.

Coping, social support and quality of life over time after myocardial infarction.

AIM: This paper describes gender differences in perceived coping, social support and quality of life 1, 4 and 12 months after myocardial infarction. BACKGROUND: There is a shortage of studies with a longitudinal research design investigating coping, social support and quality of life in women and men after myocardial infarction. METHODS: A longitudinal, descriptive and comparative design was used for the study, which included 74 women and 97 men. At 12 months, 60 women and 88 men remained. Data were collected using the Jalowiec Coping Scale, a social support questionnaire, the SF-36 Health Survey (health-related quality of life) and the Quality of Life Index-Cardiac version (quality of life). The data were collected during the period 1999-2001. RESULTS: No statistically significant changes over time in coping assessments emerged in the study group, except for fatalistic coping, which diminished over time in men. Women used more evasive coping than men at 4 and 12 months. The perceived efficiency in coping with physical aspects of the heart disease increased. More women than men perceived available support from grandchildren and staff of the church. Health-related quality of life increased in women and men in physical functioning, role-physical, vitality, social functioning, and role-emotional scales. Moreover, an improvement in the mental health scale was evident in women and a reduction in pain in men. No statistically significant gender differences were found for quality of life at any point in time. CONCLUSIONS: The findings can be used to inform caregivers that optimistic, self-reliant and confrontational coping were the most frequently used by both women and men over the first year after myocardial infarction, and that confrontational coping has been shown to have positive outcomes in the longer term. Nurses should tell women about the importance of seeking prompt treatment and discuss health problems with caregivers and significant others. Care planning should include family members and significant others so that they can support and encourage patients to cope with problems in daily life.

Physical and functional interactions between Zic and Gli proteins.

Zic and Gli family proteins are transcription factors that share similar zinc finger domains. Recent studies indicate that Zic and Gli collaborate in neural and skeletal development. We provide evidence that the Zic and Gli proteins physically and functionally interact through their zinc finger domains. Moreover, Gli proteins were translocated to cell nuclei by coexpressed Zic proteins, and both proteins regulated each other's transcriptional activity. Our result suggests that the physical interaction between Zic and Gli is the molecular basis of their antagonistic or synergistic features in developmental contexts and that Zic proteins are potential modulators of the hedgehog-mediated signaling pathway.

A randomized trial of geriatric liaison intervention in elderly medical inpatients.

OBJECTIVE: The aim of this study was to examine the effect of psychogeriatric intervention in a group of elderly medical inpatients over 75 years of age. In addition to usual care, intervention consisted of multidisciplinary joint treatment by a psychogeriatric team. The main purpose of intervention was to obtain the optimal level of physical functioning. METHOD: In a prospective randomized trial the effect of the intervention (N = 140) compared with usual care (N = 97) was estimated for physical functioning, length of stay, and nursing home placement within 12 months of discharge. RESULTS: Substantially more patients assigned to the intervention group improved in their physical functioning, and fewer became worse. The mean length of stay was 5 days shorter for the intervention group. There were more readmissions to hospital in the usual care group (29.9%) compared with the intervention group (17.4%). Of the patients assigned to the intervention treatment, 18% were admitted to a nursing home. In the usual care group this was 27%. The effects of intervention remained statistically significant for all the outcome variables after controlling for possible confounding baseline characteristics. CONCLUSIONS: The intervention we studied had clinically relevant effects on important outcome variables. Psychiatric co-morbidity was an important risk factor for the outcome of the patients in our study. By combining elements from a psychiatric and geriatric consultation service with elements from a unit-driven service, we were able to improve health care for the elderly in our hospital in a feasible and cost-effective way.

Improvement in quality of life measures in patients with refractory hepatitis C, responding to re-treatment with Pegylated interferon alpha -2b and ribavirin.

BACKGROUND: In this paper, we report the health related quality of life (HRQOL) data from patients with hepatitis C viral infection (HCV) who were refractory to prior therapy and had re-treatment with a combination of Pegylated interferon alpha-2b and ribavirin. We hypothesized that the HRQOL will improve in those patients who attain sustained viral response similar to naïve patients undergoing treatment for HCV. METHODS: HRQOL data was obtained from 152 patients enrolled into a randomized study for re-treatment of HCV refractory to prior therapy with interferon alpha-2b in combination with ribavirin. The treatment protocol was for 48 weeks and had a high and low dose arm. The HRQOL data was collected at baseline, weeks 24 and 48 of treatment, and at 24 week follow-up after treatment. A repeated measures statistical model was used for comparing the HRQOL domain scores between the responders and non-responders and the treatment groups. The responders and non-responders were also compared to the age and sex adjusted national mean scores. RESULTS: Twenty-five of the 152 (17%) patients achieved a sustained viral response. At baseline, HRQOL is lower in HCV patients compared to national norms. The norm based HRQOL domain scores for the different domains of the SF-36 instrument were as follows: physical functioning = 47.13, role-physical = 46.87, bodily pain = 48.00, general health = 44.01, vitality = 45.39, social functioning = 47.05, role-emotional = 48.88, mental health = 48.76, physical component score 43.26 and mental component score = 46.17. The scores decreased during therapy in those who would be responders and non-responders, but the pattern of change was different. During the treatment, the HRQOL domain scores of responders decrease notably in the domain of vitality. At week 48 vitality scores were worst in responders. 5 of the 8 domain scores were lower compared to baseline in non-responders. At 24 weeks post treatment follow up, HRQOL in those refractory patients who respond to re-treatment tended to be better than the national average in the domains of vitality (p = .06), social functioning (p = .06) and role-emotional (p = .03) while the non-responders improved their scores in domains of physical function and bodily pain. CONCLUSION: We conclude that patients who are to be responders and non-responders behave differently in terms of the HRQOL domain scores when re-treated with a combination of interferon alpha 2b and ribavirin. The responders sustained a significant decrease in the domain score of vitality while 5 of the 8 domain scores decrease in non-responders at the end of treatment. At the end of follow up, in responders, the HRQOL score tended to be better than the national average notably in the domains of role-emotional, vitality and social functioning. On the other hand, in non-responders, the domain scores of physical function improve, while that of role-emotional worsened.

Quality of life in adults with congenital heart disease.

OBJECTIVE: To examine the quality of life of adults with congenital heart disease. DESIGN AND SETTING: Observational, cross sectional study conducted at one general hospital in Birmingham, UK. PATIENTS: All 471 patients registered at the adult congenital heart disease clinic were sent the 36 item short form health survey (SF-36) to assess their quality of life. Questionnaires were completed by 276 (58.6%) patients (41.7% men; median (interquartile range) age 31.0 (26.3-36.0) years, range 16-85 years). RESULTS: Surprisingly, patients deemed surgically cured (for example, atrial septal defect repair) had significantly poorer quality of life in all domains (all p < 0.05), except for pain, than the general population, as determined from population normative data. Patients who had received palliative treatment reported quality of life scores similar to those who had never required cardiac surgery and to the general population, although both patient groups had significantly poorer physical functioning and overall general health perception than the general population (all p < 0.01). Patients with inoperable conditions had significantly poorer physical functioning (all p < 0.01) and overall general health perception (all p < 0.05) than all other patients, and significantly worse quality of life in all domains than the similarly aged general population. Patients with cyanotic conditions had significantly worse quality of life than age and sex matched acyanotic patients (all p < 0.01). CONCLUSIONS: Patients with inoperable or cyanotic conditions and, paradoxically, those deemed surgically cured, had the poorest quality of life among adults with congenital heart disease. However, all adults with congenital heart disease had significantly poorer levels of physical functioning and overall general health perception then similarly aged people in the general population.

IL-2 and long-term T cell activation induce physical and functional interaction between STAT5 and ETS transcription factors in human T cells.

Activation of Stat5 by many cytokines implies that it cannot alone insure the specificity of the regulation of its target genes. We have evidenced a physical and functional interaction between members of two unrelated transcription factor families, Ets-1, Ets-2 and Stat5, which could contribute to the proliferative response to interleukin 2. Competition with GAS- and EBS-specific oligonucleotides and immunoassays with a set of anti-Stat and anti-Ets families revealed that the IL-2-induced Stat5-Ets complex recognizes several GAS motifs identified as target sites for activated Stat5 dimers. Coimmunoprecipitation experiments evidenced that a Stat5/Ets-1/2 complex is formed in vivo in absence of DNA. GST-pull down experiments demonstrated that the C-terminal domain of Ets-1 is sufficient for this interaction in vitro. Cotransfection experiments in Kit225 T cells resulted in cooperative transcriptional activity between both transcription factors in response to a combination of IL-2, PMA and ionomycin. A Stat5-Ets protein complex was the major inducible DNA-binding complex bound to the human IL-2rE GASd/EBSd motif in long-term proliferating normal human T cells activated by CD2 and CD28. These results suggest that the inducible Stat5-Ets protein interaction plays a role in the regulation of gene expression in response to IL-2 in human T lymphocytes.

Fluticasone propionate improves quality of life in patients with asthma requiring oral corticosteroids.

BACKGROUND: Fluticasone propionate is a potent inhaled corticosteroid that is effective in improving pulmonary function and symptoms in patients with asthma. OBJECTIVE: To evaluate the effects of fluticasone propionate on quality of life in patients with severe asthma requiring oral corticosteroids. METHODS: A total of 96 patients with severe asthma participated in a randomized, double-blind, placebo-controlled, parallel-group, oral steroid-sparing study. Patients received fluticasone propionate aerosol, 750 or 1000 micrograms bid, or placebo for 16 weeks; 91 of these patients continued in a 1-year open-label study, in which everyone initially received fluticasone propionate, 1000 micrograms bid. At regular intervals, patients completed the Medical Outcomes Study Short Form-36 (SF-36), a general health status questionnaire measuring eight dimensions of quality of life, plus one question on change in health from the previous year. RESULTS: Compared with the US population, patients scored significantly lower at baseline for five of eight SF-36 dimensions (P < .01). After 16 weeks, patients receiving fluticasone propionate, 1000 micrograms, improved significantly (P < or = .02) in physical functioning, role-physical, general health, and change in health, compared with the placebo group. After 1 year of open-label treatment with fluticasone propionate, these improvements were maintained. SF-36 scores in the placebo group during the double-blind period either worsened or remained unchanged; however, when these patients were switched to fluticasone propionate during the open-label period, their SF-36 scores also improved. Forced expiratory volume in 1 second (FEV1) at the end of the double-blind period was positively correlated with mean quality of life scores on physical functioning, role-physical, vitality, social functioning, and change-in-health status. CONCLUSION: Health-related quality of life improved in patients with severe asthma following 16 weeks of treatment with fluticasone propionate, 1000 micrograms bid. These improvements were maintained during subsequent fluticasone propionate treatment over a 1-year period.

A randomized two-year study of the effects of dynamic strength training on muscle strength, disease activity, functional capacity, and bone mineral density in early rheumatoid arthritis.

OBJECTIVE: To evaluate the impact of a 2-year program of strength training on muscle strength, bone mineral density (BMD), physical function, joint damage, and disease activity in patients with recent-onset (<2 years) rheumatoid arthritis (RA). METHODS: In this prospective trial, 70 RA patients were randomly assigned to perform either strength training (all major muscle groups of the lower and upper extremities and trunk, with loads of 50-70% of repetition maximum) or range of motion exercises (without resistance) twice a week; all were encouraged to engage in recreational activities 2-3 times a week. All patients completed training diaries (evaluated bi-monthly) and were examined at 6-month intervals. All were treated with medications to achieve disease remission. Maximum strength of the knee extensors, trunk flexors and extensors, and grip strength was measured with dynamometers. BMD was measured at the femoral neck and lumbar spine by dual x-ray densitometry. Disease activity was determined by the Disease Activity Score, the extent of joint damage by the Larsen score, and functional capacity by the Health Assessment Questionnaire (HAQ); walking speed was also measured. RESULTS: Sixty-two patients (31 per group) completed the study. Strength training compliance averaged 1.4-1.5 times/week. The maximum strength of all muscle groups examined increased significantly (19-59%) in the strength-training group, with statistically significant improvements in clinical disease activity parameters, HAQ scores, and walking speed. While muscle strength, disease activity parameters, and physical function also improved significantly in the control group, the changes were not as great as those in the strength-training group. BMD in the femoral neck and spine increased by a mean +/- SD of 0.51 +/- 1.64% and by 1.17 +/- 5.34%, respectively, in the strength-training group, but decreased by 0.70 +/- 2.25% and 0.91 +/- 4.07% in the controls. Femoral neck BMD in the 17 patients with high initial disease activity (and subsequent use of oral glucocorticoids) remained constantly at a statistically significantly lower level than that in the other 45 patients. CONCLUSION: Regular dynamic strength training combined with endurance-type physical activities improves muscle strength and physical function, but not BMD, in patients with early RA, without detrimental effects on disease activity.

Adult failure to thrive in the older rehabilitation patient.

Increasing numbers of older adults require rehabilitation therapy upon discharge from a hospital. This pilot study tested a tool developed to assess failure to thrive syndrome (FTT) in patients admitted to a long-term rehabilitation unit (N = 34), examined the association among commonly recognized FTT factors (persistent, unexpected impairment in physical function, cognitive impairment, and poor nutrition and mood state), and investigated relationships between FTT factors and discharge disposition. Patients with a high level of physical function differed from those with a low level of function in terms of age, mood state, and discharge disposition. Patients discharged home differed from patients who were unable to return home in mood state, physical function score, and admission serum albumin. Suggestions for practice and further research are offered.

Psychological and physical adjustment to breast cancer over 4 years: identifying distinct trajectories of change.

The goal of this study was to identify distinct trajectories of adjustment to breast cancer over 4 years as well as to distinguish among the different trajectories. The mental and physical functioning of 287 women with breast cancer who remained alive and disease free through 4 years of follow-up were examined. The majority of women showed slight and steady improvement in functioning with time, but subgroups of women were identified who showed marked improvement and marked deteriorations over time. Age successfully distinguished different trajectories of physical functioning. Indices of personal resources (i.e., self-image, optimism, perceived control) and social resources (i.e., social support) successfully distinguished different courses of mental and physical functioning.

Early revisit, hospitalization, or death among older persons discharged from the ED.

The purpose of this study to determine predictors of revisit, hospital admission, or death among older patients discharged from the emergency department (ED). We performed a prospective study of patients aged 65 or older in an urban ED. The primary outcomes were ED revisit, hospital admission, or death 30 or 90 days after discharge from an index ED visit. Of the 463 eligible patients, 75 (16%) experienced ED revisit, hospitalization, or death within 30 days, and 125 (27%) within 90 days. In multivariate proportional hazards models, physical functioning and mental health in the lowest tertile, and lack of supplemental insurance predicted revisit, hospitalization, or death within 30 days after ED discharge. Poor physical functioning, missing mini-mental state examination, comorbidity, and ambulance transport to the initial ED visit predicted 90-day outcome. Problems with physical functioning, mental health and supplemental insurance are potentially remediable precursors of early morbidity among older patients after ED discharge. Future research should examine whether addressing these issues among the elderly population will lessen ED return visits, hospitalization, and mortality.
