RESUMEN

OBJECTIVE: Inappropriate diagnosis and treatment of asymptomatic bacteriuria (ASB) and urinary tract infection (UTI) are leading causes of antibiotic overuse but have not been well-studied in patients with risks for complicated UTI such as neurogenic bladder (NB). Our aim was to describe ASB and UTI management in patients with NB and assess factors associated with inappropriate management. DESIGN: Retrospective cohort study. SETTING: Four Department of Veteran's Affairs (VA) medical centers. PARTICIPANTS: Adults with NB due to spinal cord injury/disorder (SCI/D), multiple sclerosis (MS), or Parkinson disease (PD) and encounters with an ASB or UTI diagnosis between 2017 and 2018. Clinical and encounter data were extracted from the VA Corporate Data Warehouse and medical record reviews for a stratified sample of 300 encounters from N=291 patients. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Prevalence of appropriate and inappropriate ASB and UTI diagnosis and treatment was summarized. Multivariable logistic regression models assessed factors associated with inappropriate management. RESULTS: N=200 UTI and N=100 ASB encounters were included for the 291 unique patients (SCI/D, 39.9%; MS, 36.4%; PD, 23.7%). Most patients were men (83.3%), >65 years (62%), and used indwelling or intermittent catheterization (68.3%). Nearly all ASB encounters had appropriate diagnosis (98%). 70 (35%) UTI encounters had inappropriate diagnosis, including 55 (27.5%) with true ASB, all with inappropriate treatment. Among the remaining 145 UTI encounters, 54 (27%) had inappropriate treatment. Peripheral vascular disease, chronic kidney disease, and cerebrovascular disease were associated with increased odds of inappropriate management; indwelling catheter (aOR 0.35, P=.01) and Physical Medicine & Rehabilitation provider (aOR 0.29, P<.01) were associated with decreased odds. CONCLUSION: Up to half of UTI encounters for patients with NB had inappropriate management, largely due to inappropriate UTI diagnosis in patients with true ASB. Interventions to improve ASB and UTI management in patients with NB should target complex patients with comorbidities being seen by non-rehabilitation providers.

RESUMEN

STUDY DESIGN: Qualitative study. OBJECTIVES: To explore how knowledge, perceptions, and beliefs about urinary tract infections (UTIs) among persons with neurogenic bladder (NB) may impact health behaviors and provider management and enhance person-centeredness of interventions to improve UTI management. SETTING: Three Veterans Affairs (VA) medical centers. METHODS: Adults with NB due to spinal cord injury/disorder (SCI/D) or multiple sclerosis (MS) with UTI diagnoses in the prior year participated in focus groups. Transcripts were coded using deductive codes linked to the Health Belief Model and inductive codes informed by grounded theory. RESULTS: Twenty-three Veterans (SCI/D, 78%; MS: 18.5%) participated in discussions. Three themes emerged: (1) UTI knowledge; (2) factors affecting the intervention environment; and (3) factors affecting modes of delivery. Knowledge gaps included UTI prevention, specific symptoms most indicative of UTI, and antibiotic side effects. Poor perceptions of providers lacking knowledge about NB and ineffective patient-provider communication were common in the Emergency Department and non-VA facilities, whereas participants had positive perceptions of home-based care. Participants perceived lower severity and frequency of antibiotic risks compared to UTI risks. Participant preferences for education included caregiver involvement, verbal and written materials, and diverse settings like peer groups. CONCLUSIONS: Identifying patient perspectives enhances person-centeredness and allows for novel interventions improving patient knowledge and behaviors about UTIs. Partnering with trusted providers and home-based caregivers and improving NB knowledge and communication in certain care settings were important. Patient education should address mental risk representations and incorporate preferences for content delivery to optimize self-efficacy and strengthen cues to action.

RESUMEN

BACKGROUND: Women veterans experience higher levels of stress-related symptoms than their civilian counterparts. Psychological stress is associated with greater inflammation and may increase risk for cardiovascular disease (CVD). Mindfulness-based stress reduction (MBSR) has been found to improve psychological well-being in other populations but no randomized controlled trials (RCT) have been conducted examining the impact of MBSR on well-being and inflammation in women veterans at risk for CVD. OBJECTIVE: Determine the effectiveness of MBSR in improving psychological well-being, cortisol, and inflammation associated with CVD in women veterans. DESIGN: The design is a RCT comparing MBSR to an active control condition (ACC) consisting of a health education program. PARTICIPANTS: Women veterans (N=164) with risk factors for CVD from the Chicagoland area participated in the study. INTERVENTION: An 8-week MBSR program with weekly 2.5-h classes was compared to an ACC consisting of an 8-week health promotion education program with weekly 2.5-h classes. MAIN MEASURES: The outcomes were psychological well-being [perceived stress, depressive symptoms, loneliness, and post-traumatic stress disorder (PTSD)] symptoms and stress-related markers, including diurnal salivary cortisol and cytokines interleukin-6 (IL-6) and interferon gamma (IFN-γ). Data were collected at baseline, 4 weeks (mid-point of intervention), 8 weeks (completion of intervention), and 6 months after completion of MBSR or ACC. KEY RESULTS: Compared to the ACC, women who participated in MBSR reported less perceived stress, loneliness, and symptoms of PTSD. Although there were no significant differences between groups or changes over time in IL-6 or IFN-γ, participants in the MBSR program demonstrated a more rapid decline in diurnal salivary cortisol as compared to those in the ACC. CONCLUSIONS: MBSR was found to improve psychological well-being and decrease diurnal salivary cortisol in women veterans at risk for CVD. Health care providers may consider MBSR for women veterans as a means by which to improve their psychological well-being.

RESUMEN

BACKGROUND: Fatigability has recently emerged in oncology as a concept that anchors patients' perceptions of fatigue to defined activities of specified duration and intensity. This study aimed to examine the psychometric properties of the Korean version of the Pittsburgh Fatigability Scale (K-PFS) for women with breast cancer. METHODS: This cross-sectional study involved 196 women with breast cancer recruited from a tertiary hospital in Seoul, Korea. Reliability was evaluated using Cronbach's alpha, and confirmatory factor analysis was conducted to examine the factor structure of the K-PFS. Four goodness-of-fit values were evaluated: (1) the comparative fit index (CFI), (2) the Tucker-Lewis index (TLI), (3) the root mean square error of approximation (RMSEA), and (4) the standardized root mean square residual (SRMR). RESULTS: Of the 196 survivors, 71.1% had greater physical fatigability (K-PFS Physical score ≥ 15) and 52.6% had greater mental fatigability (K-PFS Mental score ≥ 13). The Cronbach's alpha coefficient for the total K-PFS scale was 0.926, and the coefficients for the physical and mental fatigability domains were 0.870 and 0.864, respectively. In the confirmatory factor analysis for physical fatigability, the SRMR value (0.076) supported goodness of fit, but other model fit statistics did not (CFI = 0.888, TLI = 0.826, and RMSEA = 0.224). For mental fatigability, although three goodness-of-fit values were acceptable (CFI = 0.948, TLI = 0.919, and SRMR = 0.057), the RMSEA value (0.149) did not indicate good model fit. However, each item coefficient was statistically significant (> 0.5), and the K-PFS was therefore found to be valid from a theoretical perspective. CONCLUSION: This study provides meaningful information on the reliability and validity of the K-PFS instrument, which was developed to meet an important need in the context of breast cancer survivors. Additional research should examine its test-retest reliability and construct validity with performance measures.

RESUMEN

BACKGROUND: Investigators conducting studies that include potentially suicidal individuals are obligated to develop a suicide risk management (SRM) protocol. There is little available in the literature to guide researchers in SRM protocol development. OBJECTIVES: The aim of the study was to describe an SRM protocol developed for a randomized controlled trial (RCT) currently enrolling cardiac patients who report moderate to severe levels of hopelessness. METHODS: The SRM protocol identifies suicidal ideation and measures ideation severity through use of the Columbia-Suicide Severity Rating Scale risk factor questions. Based on responses, study participants are deemed safe or at low, moderate, or high risk for suicide. The SRM protocol guides research staff through a plan of action based on risk level. The protocol further guides staff through a plan over the course of this prospective study-from hospital enrollment to home-based visits. RESULTS: Research staff are well trained to identify suicidal ideation risk factors, initiate specific questioning about suicidal intent, determine level of risk, identify protective factors and a safe environment, and make referrals if needed. Of the 51 patients hospitalized with cardiac disease who reported moderate to severe hopelessness, 43 scored at a safe suicide risk level and 8 scored at low risk. Thirty-five of the 51 patients enrolled in the RCT. Of the 35 participants who received home visits to date, there have been three instances of low and one instance of moderate suicide risk. The SRM protocol has been consistently and accurately used by research personnel in both hospital and home settings. One modification has been made to the protocol since study activation, namely, the addition of an assessment of counseling history and encouragement of continued counseling. Booster training sessions of research staff will continue throughout the course of the RCT. DISCUSSION: Use of the SRM protocol identifies study participants who are safe or at risk for suicide in both hospital and home settings, and research staff can refer participants accordingly. CONCLUSION: The SRM protocol developed for this RCT can serve as a model in the development of SRM protocols for future research in acute care, community, or home-based settings.

RESUMEN

BACKGROUND: Cognitive impairment is a common complication of aging that is also associated with chronic kidney disease (CKD). Vascular dysfunction has been implicated as a potential cause of cognitive impairment in older adults, with particular deficits noted in those with CKD. AIMS: To determine the differences in cognitive function and vascular compliance in older adults with and without CKD with preclinical cognitive impairment and the relationship between these factors. METHODS: Utilizing a cross-sectional approach, 48 older adults with preclinical cognitive impairment (24 with and 24 without CKD) were evaluated for performance on a test of global cognition and executive function, and vascular compliance via tonometry and ultrasound. RESULTS: Cognitive function and some indicators of vascular function were significantly different in older adults with and without CKD. Global cognition was correlated with carotid-femoral pulse wave velocity (r = - 0.36, p = 0.02) in the entire sample. Vascular function was not correlated with executive function. DISCUSSION: Older adults with preclinical cognitive impairment and CKD had different cognitive and vascular function than those without CKD, and an indicator of vascular function may have a relationship with cognitive function in older adults. CONCLUSIONS: The findings of this study support the assessment of cognitive and vascular function in older adults with and without CKD with preclinical cognitive impairment.

RESUMEN

Hopelessness is associated with decreased physical activity (PA) and increased adverse events and death in patients with ischemic heart disease (IHD). Rates of PA in patients with IHD continue to be low in both hospital-based cardiac rehabilitation and home settings. While researchers have investigated strategies to increase PA among patients with IHD, interventions to promote PA specifically in IHD patients who report hopelessness are lacking. We describe the protocol for a NIH-funded randomized controlled trial designed to establish the effectiveness of a 6-week intervention (Heart Up!) to promote increased PA in IHD patients who report hopelessness. Participants (n = 225) are randomized to one of three groups: (1) motivational social support (MSS) from a nurse, (2) MSS from a nurse plus significant other support (SOS), or (3) attention control. Aims are to: (1) test the effectiveness of 6 weeks of MSS and MSS with SOS on increasing mean minutes per day of moderate to vigorous PA; (2) determine the effects of change in moderate to vigorous PA on hopelessness; and (3) determine if perceived social support and motivation (exercise self-regulation) mediate the effects of the intervention on PA. A total of 69 participants have been enrolled to date. The protocol has been consistently and accurately used by research personnel. We address the protocol challenges presented by the COVID-19 pandemic and steps taken to maintain fidelity to the intervention. Findings from this study could transform care for IHD patients who report hopelessness by promoting self-management of important PA goals that can contribute to better health outcomes.

RESUMEN

BACKGROUND: The COVID-19 pandemic highlighted nurses' compassionate presence during stressful conditions. Strategies to reduce workplace stress are needed. PURPOSE: The purpose of this study was to evaluate a stress reduction strategy, an Internet-based Mantram Repetition Program (MRP), for nurses caring for hospitalized Veterans. METHODS: A one group pre-/post-test design was used to assess change in nurses' perceived outcomes after participating in the MRP. A post-test-only design was used to assess hospitalized Veterans' perceptions of nursing presence and satisfaction with care. Qualitative interviews were used to supplement quantitative data. FINDINGS: Patients perceived high levels of presence and satisfaction with care. Post MRP, nurses perceived increased mindfulness, compassion satisfaction, spiritual well-being, and nursing presence. Increased mindfulness was associated with greater compassion satisfaction and less burnout. DISCUSSION: For nurses working on the front lines of patient care, the potential for experiencing stress and burnout is a reality. Participating in a MRP could lessen these effects and facilitate nursing presence.

RESUMEN

Older adults with preclinical cognitive impairment can have chronic conditions and lifestyle factors that influence health. Sedentary behavior is common in older adults with and without chronic kidney disease (CKD). The objective of the current study was to determine the differences in sedentary behavior for older adults with preclinical cognitive impairment with and without CKD. Our study evaluated 48 older adults with preclinical cognitive impairment with and without CKD who underwent assessment of sedentary behavior via accelerometry. We found that older adults with preclinical cognitive impairment with and without CKD were sedentary, but there were no significant differences between groups. Fragmentation index was different (p < 0.05), with a lower fragmentation index found in those with CKD. Sedentary behavior should be assessed and evaluated as a potential target for interventions to improve health in these at-risk older adults; however, further investigation is needed.

RESUMEN

Cognitive impairment and vascular dysfunction are common in older adults with and without chronic kidney disease (CKD). Older adults with and without CKD are also sedentary - a behavior associated with cognitive and vascular function. The objective of this study was to explore whether sedentary behavior influenced the relationship between cognitive and vascular function in older adults with preclinical cognitive impairment with and without CKD. In our study, 48 older adults underwent assessment of cognition, vascular compliance, and sedentary behavior, and relationships were explored with regression moderation analysis. Sedentary time and breaks did not moderate the relationship between vascular and cognitive function. Although significant moderation was not found, cognition, vascular function, and sedentary behavior are important to assess when evaluating older adults with and without CKD.

RESUMEN

Rationale: Patients managed at a long-term acute-care hospital (LTACH) for weaning from prolonged mechanical ventilation are at risk for profound muscle weakness and disability. Objectives: To investigate effects of prolonged ventilation on survival, muscle function, and its impact on quality of life at 6 and 12 months after LTACH discharge. Methods: This was a prospective, longitudinal study conducted in 315 patients being weaned from prolonged ventilation at an LTACH. Measurements and Main Results: At discharge, 53.7% of patients were detached from the ventilator and 1-year survival was 66.9%. On enrollment, maximum inspiratory pressure (Pimax) was 41.3 (95% confidence interval, 39.4-43.2) cm H2O (53.1% predicted), whereas handgrip strength was 16.4 (95% confidence interval, 14.4-18.7) kPa (21.5% predicted). At discharge, Pimax did not change, whereas handgrip strength increased by 34.8% (P < 0.001). Between discharge and 6 months, handgrip strength increased 6.2 times more than did Pimax. Between discharge and 6 months, Katz activities-of-daily-living summary score improved by 64.4%; improvement in Katz summary score was related to improvement in handgrip strength (r = -0.51; P < 0.001). By 12 months, physical summary score and mental summary score of 36-item Short-Form Survey returned to preillness values. When asked, 84.7% of survivors indicated willingness to undergo mechanical ventilation again. Conclusions: Among patients receiving prolonged mechanical ventilation at an LTACH, 53.7% were detached from the ventilator at discharge and 1-year survival was 66.9%. Respiratory strength was well maintained, whereas peripheral strength was severely impaired throughout hospitalization. Six months after discharge, improvement in muscle function enabled patients to perform daily activities, and 84.7% indicated willingness to undergo mechanical ventilation again.

RESUMEN

A person's beliefs about their chronic condition (illness representations) influence health and treatment outcomes. Recently, researchers have used clustering approaches to identify subgroups with different patterns of beliefs about their illness, with some subgroups having more favorable health outcomes than others. To date, these findings have not been synthesized. The purpose of this systematic review of the literature was to synthesize results of studies that used clustering approaches to analyze illness representation in chronic disease populations, in order to characterize the clusters and their relationship to health outcomes. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines we searched CINAHL, PsycInfo, and PubMed. To be included, studies had to be (a) peer reviewed, (b) in English, (c) performing a cluster analysis (CA), latent class analysis (LCA), or latent profile analysis (LPA), (d) using only illness representation (IR) subscales to form clusters, (e) measuring illness representation with the Illness Perception Questionnaire (IPQ-R), (f) in a chronic condition sample, and (g) measuring health-related outcomes. Twelve studies were included. Across studies, the number of clusters found ranged from two to three. In all studies, an association was found between illness representation group and at least one of their health outcomes. Illness representation clusters associated with favorable outcomes usually included lower disease-related consequences, fewer symptoms, less negative emotion, and a more stable disease pattern. The results of this review indicate that the relationship between the patterns of the illness representation profiles and health outcomes transcend diseases. Additionally, some dimensions of illness representation may be more important drivers of group membership than others.

RESUMEN

Physical inactivity and sleep disturbance are more problematic in patients with chronic obstructive pulmonary disease (COPD) than in healthy individuals. The purpose of the study was to identify impacts of nighttime sleep on next-day physical activity in COPD patients. The study included 52 COPD patients reporting disturbed sleep. Sleep and physical activity were measured using an accelerometer for 5 days. Increased sleep latency was associated with less next-day physical activity during the afternoon (4-6 p.m.). Greater waking duration/times were associated with less next-morning (6-8 a.m.) physical activity. Greater total sleep time was associated with less next-morning (12-9 a.m.) physical activity, and greater sleep efficiency was associated with less next-morning (1-3 a.m.) and more next-evening (6-7 p.m.) physical activity. Results suggest that sleep disturbance had varying influences on next-day hourly physical activity. These results support the potential value of sleep management in promoting physical activity in COPD patients.

RESUMEN

BACKGROUND: During exercise-training patients with chronic obstructive pulmonary disease (COPD) can entrain their breathing pattern to visual-feedback cues as to achieve a slower respiratory rate and prolong exhalation. The result is an improvement in exercise tolerance and a reduction in dynamic hyperinflation. Acoustic stimuli, including metronome-generated acoustic stimuli, can entrain human movements. Accordingly, we hypothesized that exercise duration and dynamic hyperinflation would be less after exercise-training plus breathing-retraining using a metronome-based acoustic-feedback system than after exercise-training alone. METHODS: Of 205 patients with COPD [FEV1 = 44 ± 16% predicted (± SD)] recruited, 119 were randomly assigned to exercise-training plus breathing-retraining using acoustic feedback (n = 58) or exercise-training alone (n = 61). Patients exercised on a treadmill thrice-weekly for 12 weeks. Before and at completion of training, patients underwent constant-load treadmill testing with inspiratory capacity measures every 2 min. RESULTS: At completion of training, improvements in exercise duration in the breathing-retraining plus exercise-training and exercise-training alone groups were similar (p = 0.35). At isotime, inspiratory capacity increased (less exercise-induced dynamic hyperinflation) by 3% (p = 0.001) in the breathing-retraining plus exercise-training group and remained unchanged in the exercise-alone group. The between-group change in inspiratory capacity, however, was not significant (p = 0.08). CONCLUSIONS: In patients with COPD, breathing-retraining using a metronome-based acoustic feedback did not result in improved exercise endurance or decreased dynamic hyperinflation when compared to exercise-training alone.

RESUMEN

INTRODUCTION: In mechanically ventilated patients, nonvolitional assessment of quadriceps weakness using femoral-nerve stimulation (twitch force) while the leg rests on a right-angle trapezoid or dangles from the bed edge is impractical. Accordingly, we developed a knee-support apparatus for use in ventilated patients. METHODS: Ninety subjects (12 ventilated patients, 28 ambulatory patients, and 50 healthy subjects) were enrolled. Twitches with leg-dangling, trapezoid, and knee-support setups were compared. RESULTS: Knee-support twitches were similar to trapezoid twitches but smaller than leg-dangling twitches (P < 0.0001). Inter- and intraoperator agreement was high for knee-support twitches at 1 week and 1 month. In ventilated patients, knee-support twitches were smaller than in healthy subjects and ambulatory patients (P < 0.004). DISCUSSION: The new knee-support apparatus allows accurate recording of quadriceps twitches. The ease of use in ventilated patients and excellent inter- and intraoperator agreement suggest that this technique is suitable for cross-sectional and longitudinal studies in critically ill patients.

RESUMEN

BACKGROUND: Predictors of trust in healthcare providers and the healthcare system have never been studied in Korean Americans (KA) despite the fact that trust plays an important role in health behaviors. The purpose of this study is to examine factors influencing trust in the healthcare system and providers among KA women. METHODS: Data were collected in 196 KA women examining the effects of perceived discrimination and trust on breast cancer screening in the Chicago metropolitan area. Path analysis was used to identify factors influencing trust in the healthcare system and providers. RESULTS: Acculturation was positively related to trust in healthcare providers (ß = .15, p =. 002), and discrimination in the healthcare system was inversely related to trust in healthcare providers (ß = -.60, p <. 001). Length of stay in the US was inversely related to distrust in the healthcare system (ß = -.14, p <. 001), and discrimination in healthcare was positively related to distrust in the healthcare system (ß = .60, p <. 001). Trust in healthcare providers and distrust in the healthcare system were moderately correlated (r = .51, p < .001). CONCLUSION: Higher levels of acculturation and lower levels of perceived discrimination were identified as predictors of higher levels of trust in healthcare providers. A shorter stay in the US and higher levels of discrimination were identified as predictors of higher levels of distrust in the healthcare system. Perceived discrimination is a target for interventions to enhance trust in the healthcare system, and therefore reduce healthcare disparities in KAs.

RESUMEN

AIMS AND OBJECTIVES: To clarify the meaning of sleep disturbance in people with diabetes and examine its antecedents, attributes and consequences through concept analysis. BACKGROUND: Sleep is crucial for health, and people with diabetes are frequently beset with disturbances in their sleep. The concept of sleep disturbance in people with diabetes has not been clearly defined. The inconsistent use of sleep disturbance has created confusion and impeded our understanding of the sleep in people with diabetes. This analysis will provide a conceptual foundation of sleep disturbance in diabetes, thereby facilitating more effective means for assessment and treatment. DESIGN: Concept analysis. METHODS: A systematic search without time restriction on the publication year was carried out using PubMed, CINAHL, PsycINFO, Web of Science and ProQuest Dissertations and Theses. Rodgers's method of evolutionary concept analysis guided the analysis. Inductive thematic analysis was conducted to identify the attributes, antecedents and consequences. RESULTS: Based on the 26 eligible studies, two major attributes are that sleep disturbance is a symptom and is characterised by impaired sleep quality and/or abnormal sleep duration. Two antecedents are diabetes-related physiological change and psychological well-being. Sleep disturbance can result in impaired daytime functioning, glucose regulation and quality of life. CONCLUSIONS: Defining the concept of sleep disturbance in people with diabetes facilitates consistent use and effective communication in both practice and research. Sleep disturbance in people with diabetes is a complex symptom that includes impaired sleep quality and/or abnormal sleep duration. This paper contributes to the current knowledge of sleep in people with diabetes. Future research on antecedents and consequences of sleep disturbance is necessary for further clarifications. RELEVANCE TO CLINICAL PRACTICE: Findings from this paper underscore the need for nursing education, clinical assessment and effective management of sleep disturbance in people with diabetes.

RESUMEN

Intensive cancer treatment followed by hematopoietic stem cell transplantation (HCT) results in moderate to severe fatigue and physical inactivity, leading to diminished functional ability. The purpose of this study was to determine the efficacy of an exercise intervention, strength training to enhance early recovery (STEER), on physical activity, fatigue, muscle strength, functional ability, and quality of life after HCT. This single-blind, randomized clinical trial compared strength training (n = 33) to usual care plus attention control with health education (UC + AC with HE) (n = 34). Subjects were stratified by type of transplantation and age. STEER consisted of a comprehensive program of progressive resistance introduced during hospitalization and continued for 6 weeks after hospital discharge. Fatigue, physical activity, muscle strength, functional ability, and quality of life were assessed before HCT hospital admission and after intervention completion. Data were analyzed using split-plot analysis of variance. Significant time × group interactions effects were noted for fatigue (P = .04). The STEER group reported improvement in fatigue from baseline to after intervention whereas the UC + AC with HE group reported worsened fatigue from baseline to after intervention. Time (P < .001) and group effects (P = .05) were observed for physical activity. Physical activity declined from baseline to 6 weeks after hospitalization. The STEER group was more physically active. Functional ability tests (timed stair climb and timed up and go) resulted in a significant interaction effect (P = .03 and P = .05, respectively). Subjects in the UC + AC with HE group were significantly slower on both tests baseline to after intervention, whereas the STEER group's time remained stable. The STEER group completed both tests faster than the UC + AC with HE group after intervention. Study findings support the use of STEER after intensive cancer treatment and HCT. Strength training demonstrated positive effects on fatigue, physical activity, muscle strength, and functional ability. The exact recovery patterns between groups and over time varied; the STEER group either improved or maintained their status from baseline to after intervention (6 weeks after hospital discharge) whereas the health education group generally declined over time or did not change.

RESUMEN

BACKGROUND: Patients with type 2 diabetes mellitus (DM), obesity, and chronic kidney disease (CKD) are generally physically inactive and may benefit from exercise. Our objective was to determine the effects of structured exercise on physical fitness, kidney function, endothelial function, inflammation, and body composition in such patients. METHODS: In this randomized, controlled trial, 36 male patients (age 49-81) were randomly assigned to exercise + diet management (n = 18) or diet alone (n = 18). Participants were eligible if they had type 2 DM, body mass index >30 kg/m2, CKD stages 2-4, and persistent proteinuria (>200 mg/g creatinine for >3 months). The exercise intervention was a 12-week (3 days per week) program of aerobic and resistance training followed by 40 weeks of home exercise. The primary outcome measure was change from baseline in urine protein to creatinine ratio (UPCR) at 12 and 52 weeks. RESULTS: Thirty-two participants completed the study (14 exercise + diet, 18 diet-alone group). The change from baseline in UPCR was slightly greater in the diet-alone group at 12 weeks but not at 52 weeks. Changes in both symptom-limited and constant-workrate treadmill times were significantly higher in the exercise + diet group at 12 weeks but not at 52 weeks. There were no significant differences in urine albumin to creatinine ratio, estimated glomerular filtration rate, endothelial function, inflammation, or body composition between the groups. CONCLUSIONS: In obese diabetic subjects with CKD, structured exercise improved exercise capacity but not body composition or renal function.
