Background: Exercise training during hospitalization may prevent loss of physical function and hyperglycemia in patients with type 2 diabetes. The aim of this study was to assess motives and barriers to exercise training in hospitalized patients with type 2 diabetes. Methods: Data were collected using a questionnaire about motives and barriers to exercise training during hospitalization. Additional data for clinical characteristics of the participants were collected from patient records. Results: 79 patients participated (mean ± SD age 72 ± 12 years; 42% women), of whom 25% had a low level of education and 46% lived alone. The median (IQR) length of the stay was 6 (4–10) days. A total of 67% of the participants wished to be more physically active. Walking as exercise was preferred by 51%. The most frequently reported barriers to exercise training were bodily pain (48%) and dizziness (42%). Low vs. high level of education, and living alone vs. being married/living with a partner were associated with reduced odds of a wish to be more physically active, odds ratio (OR) 0.15 [95% CI 0.03; 0.76], p = 0.022, and 0.21 [0.05; 0.82], p = 0.025, respectively. Conclusion: Two out of three hospitalized patients with type 2 diabetes wished to be more physically active during admission. Bodily pain was a barrier to exercise training and needs attention in training programs. As a low level of education was associated with reduced odds of a wish to be more active, a strategy to include all patients in training programs which considers social inequality is needed.

Introduction. The aim was to compare changes in physical function and quality of life (QOL) after an exercise training programme to patients with type 2 diabetes mellitus (T2DM) in a municipality and a hospital setting and to compare the patients’ physical function and QOL with an age- and sex-matched general population. Methods. Patients with T2DM were stratified to exercise training in a municipality ( n = 26 ) or a hospital ( n = 46 ), respectively. The training was one hour twice weekly for 12 weeks. The outcomes were physical function (30 sec chair stand test (CST)) and QOL (using the SF-36). The data for the general population were collected from previous reference studies. Results. Fifty-one (71%) participants completed the intervention. The CST results improved in both groups with no difference between the municipality and hospital groups (1.6 [0.1; 3.1] vs. 3.5 [2.3; 4.8] no., respectively, p = 0.062 ). The QOL scales physical function and general health increased more in the municipality group than in the hospital group (10.5 [2.8; 18.2] vs. -1.2 [-7.9; 5.5], respectively, p = 0.031 , and 8.3 [2.3; 14.4] vs. -0.2 [-5.6; 5.1], respectively, p = 0.042 ). Dropout ( n = 21 ) during the intervention was associated with reduced QOL at baseline. The patients’ CST results at baseline were reduced compared to the general population ( 11.8 ± 3.5 vs. 18.9 ± 3.3 , respectively, p < 0.001 ). All QOL scales apart from social function were reduced in the patients compared to the general population. Conclusion. Patients in a 12-week exercise training programme in a hospital or a municipality setting had significantly lower QOL compared to an age- and sex-matched population sample. Similar improvements in physical function were observed in patients after completion of the exercise programme irrespective of exercise setting, whereas patient exercising in a municipality setting had higher positive changes in QOL than patients undergoing the same exercise programme in a hospital setting.

To investigate the effect of exercise training on musculoskeletal pain in patients with type 2 diabetes.The intervention was exercise twice weekly for 12 weeks. The primary outcome was musculoskeletal pain assessed using a 0-10 Numeric Rating Scale (NRS) in 11 body sites. Secondary outcomes were use of analgesics, glycaemic control and body weight.The participants (n = 69) were 66 ± 10 years old, 38 were men and 50 completed the intervention. Pain in the limbs was more frequently reported by the participants compared to a matched general population (80.9% vs 65.3%, p = 0.007). The participants who had any pain at baseline (NRS 0) and severe pain (NRS 3) reported significantly decreased pain in the feet, calf muscles, knees, thighs, hips, lower back and arms after the training period. Use of analgesics was unchanged, HbA1c (mmol/mol) decreased from 60 ± 15 to 54 ± 11, p 0.001 and body weight (kg) decreased from 100.5 ± 19.1 to 98.6 ± 17.7, p = 0.005.The participants with type 2 diabetes reported more frequent pain than a matched general population. The training intervention was associated with reduced musculoskeletal pain. Reduced pain may together with a positive impact on glycaemic control be an important motivational factor in patients with type 2 diabetes to perform exercise training.

ObjectiveEnd-stage kidney disease and hemodialysis (HD) treatment are associated with a high symptom burden in many patients. This study aimed at updating patient-reported outcomes concerning quality of life, fatigue, anxiety, and depression in HD patients treated in a single center in order to assess the need for palliative care provision.MethodA cross-sectional design, in which a sample of patients treated at a single HD department (Rigshospitalet, Denmark) between January and June 2019, was analyzed using the Kidney Disease Quality of Life Short Form, the Multidimensional Fatigue Inventory, and the Hospital Anxiety and Depression Scale. In addition, we compared the results with previously published data from the same department (2000) and with an age- and sex-matched sample from the Danish general population (1997/2014). Chi-square and t-tests were used for comparisons.ResultsScreened patients = 242, included = 141, analyzed = 131 (70.2% male, mean age = 61.3 years). HD patients reported low scores for quality of life, high scores for fatigue, and approximately 30% had anxiety/depression. Regarding quality of life, they had significantly lower scores on general health (P ≤ 0.000), vitality (P = 0.009), social functioning (P = 0.001), mental health (P = 0.007), and mental component (P = 0.005) compared with former data of HD patients. Moreover, they reported significantly poorer quality of life and worse fatigue compared with the general Danish population.Significance of resultsIn the patients undergoing HD, quality of life was poor and worsened when compared with former HD patients’ data. Additionally, fatigue, depression, and anxiety in HD patients were prevalent. A clear need for palliative care provision was observed.

Aims. The purpose was to assess the reproducibility of glucose changes during three sessions of standardized moderate intensity continuous training of cycling on an individual level in people with type 1 diabetes. Methods. Twelve adults (six females) with type 1 diabetes performed three test sessions on an ergometer bicycle (30 min, 67% of predicted heart rate) on three different days. The participants were 36.5 (26.6-45.5) (median, IQR) years old, and their HbA1c was 65 ± 15 mmol/mol ( mean ± SD ). Two hours before the tests, the participants had a standard meal. Interstitial glucose (IG) and capillary glucose (CG) were measured using an iPro2 Medtronic continuous glucose monitor and the Bayer Contour XT-device, respectively. Prior to the test sessions, resting heart rate was measured using a digital blood pressure monitor to estimate the desired intensity of the exercise. Results. The average within-participant relationship between the average slope in glucose during sessions 2 and 1 was in IG -0.29 (95% CI -1.11; 0.58) and in CG -0.04 (-0.68; 0.77). Between sessions 3 and 2, IG is 0.18 (-0.27; 0.64) and in CG 0.13 (-0.25; 0.55). Between sessions 3 and 1, IG was 0.06 (-0.57; 0.71) and in CG 0.06 (-0.39; 0.52). The results indicate low reproducibility at participant levels and remained unchanged after adjustment for baseline glucose values. Conclusion. On an individual level, the glucose declines during three standardized sessions of PA were not associated with identical responses of the measured IG and CG levels. An overall anticipated decline of glucose concentrations was found in the moderate intensity cycling sessions. This highlights the importance of regular CG measurements during and after physical activity and awareness towards potential exercise-induced hypoglycemia in persons with type 1 diabetes.

Yet, research in pain characteristics including prevalence, localization, and intensity in people with COPD are sparsely researched.Aim: To investigate self-reported pain prevalence, localization and intensity of pain in people with and without COPD, and to investigate the association between pain intensity and PAL among participants with COPD.Methods: Data were derived from the Danish Health and Morbidity Survey in 2017. The study population was restricted to individuals aged ≥ 35 years. Data included pain intensity assessed on the Numeric Rating Scale (NRS) and localization, PAL, QoL, sleep disturbance, comorbidities, sociodemographic and behavioral factors.Results: In all, 528 participants with COPD and 8184 participants without COPD (51% females, mean ±SD age 67.1± 11.4 years) were analyzed. Pain prevalence within the past 14 days was significantly higher in participants with COPD vs nonCOPD (72.7% vs 57.7%, p< 0.001) and mainly located in the limbs, thorax, and lower back. COPD was associated with the prevalence of chronic pain (≥ 6 months) (OR: 2.78, 95%CI: 2.32; 3.34, p< 0.001). Participants with COPD reported a higher pain intensity compared to those with nonCOPD with a mean difference of 1.04 points (95%CI: 0.75; 1.32, p< 0.001) on the NRS. In the adjusted multiple logistic regression analysis, pain intensity was negatively associated with odds of being physical active (OR: 0.72, 95%CI: 0.61; 0.85, p< 0.001).Conclusion: Pain is more prevalent in people with self-reported COPD. After adjustment for age and gender, COPD was associated with an elevated pain intensity. Sleep disturbance and multimorbidity had the most pronounced impacts on pain intensity in the multiple linear regression model. In participants with COPD, increased pain intensity was negatively associated with being physically active.Keywords: COPD, pain, cross-sectional, physical activity, quality of life

Aims: The aim was to investigate the association between socioeconomic position (SEP) and physical activity, alcohol consumption and smoking, motivation to change lifestyle and health advices from general practitioners (GPs) in individuals with diabetes. Methods: Data were provided by the Danish National Health Survey 2013 and 7504 adults (⩾ 40 years) with diabetes were included. Educational level was used as SEP indicator and categorized into low, middle and high SEP. Dependent variables included physical activity, alcohol consumption, smoking, motivation to change lifestyle and GP lifestyle advices. Multiple logistic regression analyses adjusted for age, body mass index and ethnic background were performed. Results: Higher SEP were associated with reduced odds of being physically inactive (middle SEP odds ratio (OR) men 0.58 (95% confidence intervals 0.47–0.72) and women 0.59 (0.47–0.75)) and non-smoking (middle SEP OR men 0.74 (0.59–0.93) and high SEP OR women 0.54 (0.38–0.77)) compared to participants with a low SEP. Alcohol consumption above the recommended maximum was associated with high SEP in men, OR 1.83 (1.30–2.61). Elevated SEP was associated with a motivation to increase physical activity levels (middle SEP OR men 1.45 (1.19–1.76) and women 1.35 (1.09–1.67)), high SEP was associated with none advice from GPs regarding smoking cessation among women, OR 0.47 (0.25–0.89). Conclusions: Socioeconomic position was strongly associated with lifestyle in individuals with diabetes. The most pronounced inequalities were found in physical activity levels, smoking status and the motivation to become more physically active. Municipalities and GPs may need a greater focus on SEP in interventions to change lifestyle in individuals with diabetes.

Aim. To investigate the associations between diabetes and musculoskeletal pain, osteoarthritis, osteoporosis, and rheumatoid arthritis. Methods. Self-reported data were provided by the nationwide Danish National Health Survey 2013. Inclusion criteria were age≥40 years and known diabetes status. The exposure variable was diabetes, and the outcome variables included musculoskeletal pain during the last 14 days in three body sites (back/lower back, limbs, and shoulder/neck), osteoarthritis, osteoporosis, and rheumatoid arthritis. Logistic regression analyses adjusted for age, gender, BMI, education, marital status, and physical activity were performed. Results. 9,238 participants with diabetes were 65.6±11.0 (mean±SD) years old; 55.6% were males. 99,980 participants without diabetes were 59.2±11.8 years old; 46.7% were males. Diabetes was associated with back/lower back pain (OR 1.2 (CI 95% 1.1-1.2), p<0.001), pain in the limbs (1.4 (1.3-1.4), p<0.001), shoulder/neck pain (1.2 (1.1-1.3), p<0.001), osteoarthritis (1.3 (1.2-1.4), p<0.001), osteoporosis (1.2 (1.1-1.4), p=0.010), and rheumatoid arthritis (1.6 (1.4-1.7), p<0.001). In participants with diabetes, physical activity was associated with reduced pain (e.g., back/lower back pain (0.7 (0.6-0.7), p<0.001)). Conclusion. Diabetes was associated with elevated odds of having musculoskeletal pain. Diabetes was also associated with elevated odds of having osteoarthritis, osteoporosis, and rheumatoid arthritis. The most frequent disease in individuals with diabetes was osteoarthritis. The reported pain may have negative impacts on the level of physical activity. Health-care professionals should remember to inform patients with diabetes that musculoskeletal pain, osteoarthritis, osteoporosis, and rheumatoid arthritis are not contraindications to exercise training.

To assess distal blood pressures (BPs) in ankle and toe, walking capacity, intermittent claudication symptoms, physical activity and self-rated health after intermittent vacuum treatment (IVT) for peripheral artery disease (PAD). Forty-eight patients with PAD were randomised to either a control (C)-group with lifestyle changes or lifestyle changes in combination with VacuMed® treatment thrice weekly for 6 weeks. Ankle and toe BPs were measured before, after 6 weeks of intervention and after 6 weeks follow-up. Walking capacity, intermittent claudication symptoms, physical activity and self-rated health (Likert scale) were also assessed. The ankle to brachial index (ABI) and BPs in the ankle and toe decreased after 6 and 12 weeks in both groups with no difference between the groups. In the legs with the lowest ABI at baseline in each patient, there were no differences regarding ABI, BPs and toe-systolic BP index between the groups after either the intervention or the follow-up period. The BPs decreased in both groups. The walking distance and the time to pain were unchanged in the IVT-group and increased in the C-group after the follow-up period, but without any significant differences between the groups. The level of objectively tested physical activity and self-rated health remained unchanged throughout the study in both the IVT- and the C-group. There were no differences between the changes of the self-rated health data during the study period between the IVT- and the C-group. VacuMed® had no effect per se on distal blood pressures, walking capacity, intermittent claudication symptoms, physical activity and self-rated health.

Background. Obstructive sleep apnoea (OSA) is related to type 2 diabetes (T2DM), and it may be associated with reduced inspiratory muscle strength (IMS). The aim of this study was to investigate the IMS in patients with T2DM, with or without OSA. Methods. Patients with T2DM with OSA (n=33) and without OSA (n=28) were included. The maximum IMS was tested using the POWERbreathe KH2 device. Reference IMS values were data calculated using an algorithm based on general populations and adjusted for age and gender. Results. There was no difference in IMS between the OSA group (median (range) 77 (35–124) cmH2O) and the non-OSA group (84 (33–122) cmH2O) (p=0.97). The IMS values were reduced in the OSA group compared with the reference values (92.9 (62.3–100.0) cmH2O) (p=0.030), whereas the non-OSA group did not have reduced IMS. When the IMS values of all T2DM patients were compared with reference values, the IMS values were 79 (33–124) cmH2O and 93.8 (62.3–102.4) cmH2O, respectively (p=0.017). Conclusion. No difference in IMS between patients with T2DM with or without OSA was found. However, patients with T2DM and OSA had reduced IMS compared with age- and gender-matched references whereas the non-OSA group did not have reduced IMS.

Background. The aim of this study was to investigate IL-6 and 25-hydroxyvitamin D (25-OH D) associations with muscle size and muscle function in dialysis patients.Methods. Patients were included in a 16-week control period followed by 16 weeks of high-intensity resistance training thrice weekly. IL-6 and 25-OH D were analysed after an over-night fast. Muscle fibre size was analysed in biopsies fromm. vastus lateralis. Muscle power was tested using a Leg Extensor Power Rig.Results. Patients (n=36) with IL-6 ≥ 6.49 pg/ml (median) were older and had decreased muscle power and a reduced protein intake (P<0.05) compared with patients with IL-6 < 6.49 pg/ml. IL-6 was not associated with muscle fibre size. Vitamin D deficiency (25-OH D < 50 nmol/l) was present in 51% of the patients and not associated with muscle power. IL-6 remained unchanged during the training period, whilst muscle power increased by 20–23% (P<0.001).Conclusion. Elevated IL-6 values were associated with decreased muscle power but not with decreased muscle fibre size. Half of the patients were suffering from vitamin D deficiency, which was not associated with muscle power. IL-6 was unchanged by high-intensity resistance training in dialysis patients in this study.

Background/Aims: The aim of this controlled study was to investigate the effect of high-load strength training on glucose tolerance in patients undergoing dialysis. Methods: 23 patients treated by dialysis underwent a 16-week control period followed by 16 weeks of strength training three times a week. Muscle fiber size, composition and capillary density were analyzed in biopsies obtained in the vastus lateralis muscle. Glucose tolerance and the insulin response were measured by a 2-hour oral glucose tolerance test. Results: All outcome measures remained unchanged during the control period. After strength training the relative area of type 2X fibers was decreased. Muscle fiber size and capillary density remained unchanged. After the strength training, insulin concentrations were significantly lower in patients with impaired glucose tolerance or type 2 diabetes (n = 14) (fasting insulin from 68 ± 12 (46-96) to 54 ± 10 (37-77) pmol/l, p < 0.05, 2-hour insulin from 533 ± 104 (356-776) to 344 ± 68 (226-510) pmol/l, p < 0.05, total insulin area under the curve from 1,868 ± 334 (1,268-2,536) to 1,465 ± 222 (1,094-1,913), p < 0.05). Insulin concentrations were unchanged in patients with normal glucose tolerance (n = 9). Conclusion: The conducted strength training was associated with a significant improvement in glucose tolerance in patients with impaired glucose tolerance or type 2 diabetes undergoing dialysis. The effect was apparently not associated with muscle hypertrophy, whereas the muscle fiber type composition was changed.

The aims were to investigate the prevalence of musculoskeletal pain in patients with type 2 diabetes and demonstrate possible associated factors.Nine hundred fifty-one patients completed a validated questionnaire used in The Danish Health and Morbidity Survey and results were compared to data for 2923 matched subjects from the Danish population. Musculoskeletal pain was self-reported Pain in the shoulder and neck; Low-back pain; and Pain in the arm, hand, knee and/or hip.Compared to the age, gender and region matched controls patients reported musculoskeletal pain 1.7-2.1 times as frequent (p0.001). Pain was more frequently reported in women (p0.001). Low-back pain and Pain in the arm, hand, knee and/or hip was associated with body mass index (p0.005). Low-back pain was associated with a sedentary life style, impaired quality of life and reduced physical function (p0.05).The prevalence of musculoskeletal pain was seriously increased in patients with type 2 diabetes. It was associated with body mass index, reduced quality of life, low physical function and the ability to be physical active. Focus on musculoskeletal pain in clinical practice is therefore of major importance in lifestyle interventions in type 2 diabetes.

Health related quality of life (HRQOL) has become a recognized outcome in studies of the treatment of patients undergoing hemodialysis (HD). The aim of this study was to assess changes in HRQOL reported by two different samples of patients undergoing HD in the same dialysis center in 2002 and 2015. Two samples of patients from the same Danish dialysis center completed the HRQOL questionnaire Kidney Disease Quality of Life version 1.3 in 2002 (n = 71) and 2015 (n = 81), respectively. The associations between KDQOL summery scores and the time frame were analyzed in multivariable regression analyses. The 2015 sample of patients were older compared to the 2002 sample (66 ± 13 vs. 59 ± 16 years, p = 0.003, respectively), they comprised more obese patients (20.6 vs. 3.2%, p = 0.002) and more patients with hypoalbuminemia (66.7 vs. 42.9%, p = 0.006). After confounder adjustment the time period 2015 versus 2002 was not associated with changes in the generic summery scales Physical Component Scale (β 3.9, 95% CI-0.1; 7.9, p = 0.051) and Mental Component Scale (β -2.5, 95% CI -7.6; 2.5, p = 0.322) or the disease specific summery scale Kidney Disease Component Scale (β 1.0, 95% CI -5.1; 7.1, p = 0.746). This study indicated an unchanged HRQOL when recent data were compared with data collected 13 years earlier in patients undergoing HD from a Danish dialysis center. We suggest that the included dialysis center monitor HRQOL and pay attention on interventions that may be associated with improvements of HRQOL and reduce the elevated frequency of patients with obesity or hypoalbuminemia.

Background/Aims: It is relevant to investigate health-related quality of life (HRQOL) in dialysis and chronic kidney disease (CKD) patients in order to optimise treatment. The aim of this study was to investigate HRQOL in dialysis and CKD patients, to compare results from patients treated with hemodialysis (HD) and peritoneal dialysis (PD) and to investigate the prediction of dialysis quality control parameters (blood hemoglobin, plasma albumin, and Kt/V) and tobacco smoking in disease-specific HRQOL. Methods: Seventy-one HD, 59 PD, and 63 CKD patients participated in the study. Dialysis quality control parameters were measured and the patients completed the questionnaire Kidney Disease Quality Of Life. Results: PD patients rated Dialysis Staff Encouragement and Patient Satisfaction better than HD patients (p≤ 0.05). Dialysis patients scored significant lower than the general population in all generic HRQOL scales (p ≤ 0.01), whereas CKD patients scored lower than the general population in 5 of 8 scales (p ≤ 0.05). The dialysis quality parameters did not predict dialysis patients’ disease specific HRQOL, but tobacco consumption was independently associated with low scores on a number of HRQOL scales. Conclusion: Based on the results, it is suggested to include elements of HRQOL as a supplement to standard quality control parameters. It is also suggested routinely to include information of the beneficial effects of physical activity already in the predialysis program, and to focus on smoking as a very important risk factor.

AIMS: In recent decades there has been an increased focus on non-pharmacological treatment of diabetes. The aim of this study was to investigate trends in leisure time physical activity (PA), smoking, body mass index (BMI), and alcohol consumption reported in 2000, 2005 and 2010 by Danish subjects with diabetes.METHODS: Data comprised level of leisure time PA (inactive; moderate active; medium active; high active); smoking; BMI; and alcohol consumption, provided by The Danish Health and Morbidity Surveys. Participants older than 45 years with or without diabetes were included from cross-sectional analyses from 2000, 2005 and 2010.RESULTS: In participants with diabetes, leisure time PA levels increased from 2000 to 2010: The percentage of those that were physically active increased from 53.5% to 78.2% (pCONCLUSIONS: The percentage of physically active Danish participants older than 45 years with diabetes increased from 2000 to 2010, and the most beneficial trends in life style were observed among the women. These trends may have serious implications for cardiovascular risk in Danish patients with diabetes.

The aim of this study was to assess the effect of high-intensity resistance training on satellite cell (SC) and myonuclear number in the muscle of patients undergoing dialysis.Patients (n = 21) underwent a 16-week control period, followed by 16 weeks of resistance training 3 times weekly. SC and myonuclear number were determined by immunohistochemistry of vastus lateralis muscle biopsy cross-sections. Knee extension torque was tested in a dynamometer.During training, SCs/type I fibers increased by 15%, whereas SCs/type II fibers remained unchanged. Myonuclear content of type II, but not type I, fibers increased with training. Before the control period, the SC content of type II fibers was lower than that of type I fibers, whereas contents were comparable when normalized to fiber area. Torque increased after training.Increased myonuclear content of type II muscle fibers of dialysis patients who perform resistance training suggests that SC dysfunction is not the limiting factor for muscle growth.

Background.We investigated serum testosterone and insulin-like growth factor 1 (IGF-1) levels’ associations with muscle fibre size and resistance training in male dialysis patients.Methods.Male patients were included in a 16-week control period followed by 16 weeks of resistance training thrice weekly. Blood samples were obtained to analyse testosterone, luteinizing hormone (LH), IGF-1, and IGF-binding protein 3. Muscle fibres’ size was analysed in biopsies fromm. vastus lateralis.Results.The patients’ testosterone levels were within the normal range at baseline (n=20) (19.5 (8.2–52.1) nmol/L versus 17.6 (16.1–18.0), resp.) whereas LH levels were higher (13.0 (5.5–82.8) U/L versus 4.3 (3.3–4.6),P<0.001, resp.). IGF-1 and IGF-binding protein 3 levels were higher in the patients compared with reference values (203 (59–590) ng/mL versus 151 (128–276),P=0.014, and 5045 (3370–9370) ng/mL versus 3244 (3020–3983),P<0.001, resp.). All hormone levels and muscle fibre size (n=12) remained stable throughout the study. Age-adjusted IGF-1 was associated with type 1 and 2 fibre sizes (P<0.05).Conclusion.Patients’ total testosterone values were normal due to markedly increased LH values, which suggest a compensated primary insufficiency of the testosterone producing Leydig cell. Even though testosterone values were normal, resistance training was not associated with muscle hypertrophy. This trial is registered withISRCTN72099857.

The aim of this study was to investigate the effects of high-load resistance training on the rate of force development and neuromuscular function in patients undergoing dialysis.Twenty-nine patients were tested before and after 16 weeks of resistance training. The rate of force development was tested using the Good Strength dynamometer chair. Muscle strength and neuromuscular function in the m. Vastus lateralis was estimated using electromyography in a one repetition maximum test during dynamic knee extension and during a 20 s isometric knee extension with 50% of the one repetition maximum load. Muscle biopsies from the m. Vastus lateralis were analysed for morphologic characteristics.One repetition maximum in knee extension increased by 46% (P0.001) after the training programme. Rate of force development increased by 21-38% (P0.05). The electromyography amplitude increased during 200-300 msec from 183 ± 36 μV to 315 ± 66 μV, (P0.05), whilst electromyography frequency remained unchanged. The electromyography signals, during isometric contractions, remained unchanged. A higher rate of force development was found to be significantly associated with larger type 2 muscle fibres (r=0.647).Muscle strength in patients undergoing dialysis was increased after 16 weeks of resistance training in parallel with changed neuromuscular function and greater rate of force development, both of which have important clinical implications in terms of improved physical performance.

This study aimed to compare sexual dysfunction in Danish female predialysis patients with chronic kidney disease (CKD) stage 4–5 with age-matched healthy women in Denmark. Twenty-seven adult female predialysis patients (CKD stage 4–5 ~ creatinine clearance ≤ 30 ml/min) without diagnosed depression and 54 randomly assigned healthy female controls completed the questionnaires Female Sexual Function Index, Female Sexual Distress Scale, and the Major Depression Inventory. Predialysis patients reported lower Female Sexual Function Index scores compared to the controls (14.2 ± 2.1 vs. 20.1 ± 1.7, respectively, p = 0.048), more frequent sexual distress (44 vs. 22 %, respectively, p = 0.044), and more frequent sexual dysfunction (41 vs. 17 %, respectively, p = 0.041). There was no difference between the patients’ and the controls’ depression scores (12.2 ± 2.2 vs. 8.6 ± 1.1, respectively, p = 0.180). Sexual dysfunction was found to be more than two times as frequent in Danish female predialysis patients with CKD stage 4–5 compared to age- and gender-matched healthy controls, and this result emphasizes the need for attention towards sexual function in the treatment for CKD.

Objective The aim of this study was to investigate the effects of high-load strength training and protein intake in patients undergoing dialysis with a focus on muscle strength, physical performance, and muscle morphology. Design This was a randomized controlled study conducted in three dialysis centers. Subjects Subjects for the study included 29 patients undergoing dialysis. Intervention The participants went through a control period of 16 weeks before completing 16 weeks of strength training. Before the training period, the participants were randomly assigned to receive a protein or a nonprotein drink after every training session. Main Outcome Measure Muscle strength and power were tested using the good strength equipment and the leg extensor power rig. Physical performance and function were assessed using a chair stand test and the Short Form 36 questionnaire. Muscle fiber type size and composition were analyzed in biopsies obtained from the m. vastus lateralis. Results All variables remained unchanged during the control period. After training, muscle strength and power, physical performance, and physical function increased significantly. Muscle fiber composition was changed by a relative decrease in type 2x muscle fiber number whereas muscle size at the fiber level was unchanged. There were no effects of combining the training with protein intake. Conclusions High-load strength training is associated with improvements in muscle strength and power, physical performance, and quality of life. The effects were surprisingly not associated with muscle hypertrophy, and the results did not reveal any additional benefit of combining the training with protein intake. The positive results in muscle strength and physical performance have clinically relevant implications in the treatment of patients undergoing dialysis.

The worldwide epidemic of Type 2 diabetes necessitates evidence-based self-management education programmes. The purpose of this study was to investigate the effects and costs of an empowerment-based structured diabetes self-management education programme in an unselected group of patients with Type 2 diabetes. Seven hundred and two patients undergoing treatment by general practitioners (GPs) were included. The education comprised three modules over a 12-month period. It was based on the empowerment philosophy. The education followed a written curriculum, and the educators were given special training in its use. Glycemic control (HbA1c) was found to improve from 7.34 ± 1.34 to 6.88 ± 1.09%, P < 0.001 and body weight decreased from 90.9 ± 19.3 to 87.1 ± 18.1 kg, P < 0.001, following the education programme. Moreover, significant improvements were found in terms of fasting blood glucose, blood pressure, female waist circumference, lipid profile, quality of life, physical activity and the patients' knowledge of diabetes whilst the number of visits to GPs declined. This study supports the use of an empowerment vision as a basis for an interdisciplinary group-based education programme with individuals with Type 2 diabetes. Moreover, the costs of implementing this education programme were found to be minimal.

The aims of the study were to translate the Kidney Disease Quality of Life--Short Form version 1.3 (KDQOL-SF ver. 1.3) questionnaire into Iranian (Farsi), and to then assess it in terms of validity and reliability on Iranian patients.The questionnaire was first translated into Farsi by two independent translators, and then subsequently translated back into English. After translation disparities had been reconciled, the final Iranian questionnaire was tested. An initial test-retest reliability evaluation was performed over a 10 day period on a sample of 20 patients recruited from a larger group (212 patients with end-stage renal disease on haemodialysis). Afterwards, reliability was estimated by internal consistency, and validity was assessed using known group comparisons and constructs for the patient group as a whole. Finally, the factor structure of the questionnaire was extracted by performing exploratory factor analysis.All of the scales in the questionnaire showed good test-retest reliability (i.e. intraclass correlations between test and retest scores were0.7). All of the scales met the minimal criteria (0.7) for internal consistency and Cronbach's-α ranged 0.71-0.93. Furthermore, results from a discriminate validity evaluation showed that the questionnaire could be used to discriminate between subgroups of the patients. Finally, a principal component analysis of the disease-specific scales indicated that this part of the questionnaire could be summarized into an 11 factor structure that jointly accounted for 79.81% of the variance.The Iranian version of the KDQOL-SF questionnaire is both highly reliable and valid for use with Iranian patients on haemodialysis.

This study evaluated the health-related quality of life (HRQOL) in a sample of Iranian patients undergoing maintenance hemodialysis. The data were compared with the HRQOL for the Iranian general population.Two-hundred and fifty patients undergoing hemodialysis were included using a convenience sampling approach in a cross-sectional study. Data collection was performed using a Persian translation of the Short Form-36 questionnaire in combination with demographic and clinically related questions. The collected data were analyzed using a logistic regression model with physical and mental summary scales as dependent variables.The patients' mean Short Form-36 scores were significantly lower than those obtained for the general population for all scales. Patients with longer duration of being on hemodialysis, poor adherence to treatment, higher body mass index, and comorbidity diseases suffered from a poorer physical health. Poor mental health was associated with a lower level of education, longer duration of hemodialysis, lower economic status, a lower degree of knowledge on disease, and comorbidity diseases.This study affirms the fact that patients undergoing hemodialysis suffer from poor HRQOL. In comparison with data from other studies from Asian and European countries, this sample of Iranian patients on hemodialysis had a lower HRQOL, a discrepancy that might be due to differences in life style, socioeconomic status, the general level of education of the patients, as well as physician-patient communication.

This study aimed to evaluate aspects of health-related quality of life (HRQoL) of patients with multiple sclerosis (MS) who live in Tehran and to compare data with evaluations of both the general population and MS patients in other countries.One hundred and forty patients with MS, yet without severe comorbidity, were selected according to convenience sampling in a cross-sectional study. Data were collected by means of the SF-36 questionnaire and Beck Depression Inventory (BDI). The Expanded Disability Status Scale of Kurtzke (EDSS) and Mini Mental State Examination were recorded for all patients.The mean age of the participants was 34.7 years. For all SF-36 scales, MS patients were found to have lower scores, after adjustment for sex and age, compared with the general population. BDI and EDSS scores were significantly and negatively correlated with all of the SF-36 scales. Moreover, the BDI and EDSS were found to be positively correlated with one another (r = 0.415, p0.01).The findings strongly confirm that patients with MS suffer from poor HRQoL. Depression had a strong effect on HRQoL and in order to improve HRQoL in MS patients the prevention and treatment of depression is vital.

Background: Muscle function is impaired in uraemic patients and several causes have been proposed. Deficiency of 25-hydroxyvitamin D (25-OHD), which affects muscle function in non-uraemic patients, may very well also be associated with the myopathy found in these patients. The aim of this study was to investigate the association between 25-OHD and muscle function as well as physical function in chronic kidney disease (CKD) and peritoneal dialysis (PD) patients. Methods: In this cross-sectional study, 21 adult patients with CKD stage 3–5 and 21 patients treated with PD were included. Standard biochemistry parameters were measured including 25-OHD, 1,25-dihydroxycholecalciferol (1,25-OHD) and parathyroid hormone analysis. Muscle function was determined by 30-second surface electromyography (sEMG) recordings of a right thigh muscle (vastus lateralis) and a second left finger muscle (second dorsal interosseous) under voluntary contractions. Physical function was determined using a 30-second Chair Stand Test and the Short Form 36 quality of life questionnaire. Clinical characteristics were collected from the patient records. Results: Moderate vitamin 25-OHD deficiency (Conclusions: 25-OHD deficiency was prevalent in uraemic patients in the present study. Muscle function as determined using sEMG and the Chair Stand Test was not associated with 25-OHD. The results may be biased by the limited variation in 25-OHD and masked by effects of several other variables in this very sick population.

Chronic uraemia is associated with abnormalities in skeletal muscles, which can affect their working capacity. It is also well known that the fibre-type composition of skeletal muscles influences endurance, muscle strength and power. In this study we therefore determined the size and distribution of muscle fibres and the myosin heavy-chain (MHC) isoform composition in patients on haemodialysis (HD) in order to establish any differences with values for untrained control subjects.Muscle biopsies were obtained from the vastus lateralis muscle of 14 non-diabetic patients on HD. The size and distribution of muscle fibres were evaluated using adenosine triphosphate synthase (ATPase) histochemistry, whilst MHC isoform composition was determined in muscle homogenates using sodium dodecyl sulphate-polyacrylamide gel electrophoresis. Values were compared to those for a group of age-, gender- and BMI-matched untrained control subjects. The aerobic work capacity of the patients was also determined.The MHC composition for I, IIA and IIX isoforms was found to be 35.3% +/- 18.2%, 35.9% +/- 7.1% and 28.9% +/- 15.6%, respectively, findings supported by the ATPase histochemically determined fibre-type composition of the vastus lateralis muscle. The mean fibre area of type 1 and 2 fibres was 3283 +/- 873 and 3594 +/- 1483 MICROm2, respectively. The MHC composition and the size of the type 1 fibres of the patients on HD were significantly different from those of the control subjects.The data demonstrate relatively fewer type 1 and consequently more type 2x fibres, with a corresponding change in MHC isoforms (MHC I and MHC IIX) in the skeletal muscle of patients on HD. Several patients on HD were found to have15% type 1 (or relative percentage of MHC I) fibres. Such a low percentage of type 1 fibres is very rarely observed in normal untrained subjects. Chronic uraemia more severely affects the composition than the size of fibres.

The questionnaire Kidney Disease Quality of Life Short Form version 1.3 (KDQOL-SF) is valuable for assessing the health-related quality of life in patients treated with chronic dialysis. The aim of this study was to translate and test the reliability of the KDQOL-SF for use in Denmark.Translation into Danish and back-translation into English were performed. Pilot, field and internal consistency reliability tests were performed.Cronbach's alpha coefficients for the internal reliability test ranged from 0.77 to 0.93 for the eight generic scales. In a test involving all patients, two of the disease-specific scales had Cronbach's alpha coefficients of0.70 ("social support" = 0.67; and "quality of social interaction" = 0.43). After removing one item from the scale "quality of social interaction", Cronbach's alpha reached 0.63. A test of the scores of peritoneal dialysis (PD) patients discovered low reliability for three disease-specific scales. The KDQOL-SF manual and the Danish manual for the Short Form 36 (SF36) differed in the scoring of four generic scales: "role limitation-physical", "bodily pain", "general health" and "social function".With the exception of the scale "quality of social interaction" the Danish translation of the KDQOL-SF achieved values in the internal consistency reliability test of the same level as the original U.S. version. When data were stratified according to dialysis treatment, the reliability of PD patients scores was lower. Generic data from the questionnaire SF36 should be scored according to the Danish SF36 manual.

Along with survival and other types of clinical outcome, physical, mental and social well-being are important indicators of the effectiveness of the medical care that haemodialysis (HD) patients receive. The present cross-sectional study was designed to assess self-rated health in HD patients from a large Danish HD centre compared to a Danish general population sample with similar sex and age distributions. Furthermore, employment status and associations between self-rated health and clinical, social and demographic factors were investigated.A total of 150 patients were included. They were asked to complete the Short Form 36 (SF-36) questionnaire and additional questions concerning education and employment status. The SF-36 consists of eight scales representing physical, social, mental and general health. Clinical, biochemical and dialysis adequacy data were obtained from hospital records.A total of 112 patients completed the questionnaire, giving a response rate of 75%. Compared to the general population sample, HD patients scored significantly lower on all eight SF-36 scales (p0.01), with the greatest difference being observed for items concerning physical functioning. No correlation was found between any of the eight scales and estimates of dialysis adequacy. Of patients aged 18-60 years, 22% were in employment.In a large group of Danish HD patients, self-rated health (and especially physical function) was found to be substantially impaired compared to the general population and only a small proportion of patients were employed. We believe that results obtained using the SF-36 questionnaire represent an independent marker of health status in HD patients and should be considered, together with common clinical outcome measures, when monitoring patients. Furthermore, we believe that self-rated health questionnaires are a useful tool for evaluating the need for and the effects of physical activity programmes in a dialysis unit.

Background: The number of chronic renal failure patients treated by hemodialysis (HD) is continuously increasing. Most patients have reduced physical capacity and have a high risk of cardiac and vascular diseases. The aim of this study was to determine the effects of 5 months physical exercise of HD patients’ physical capacity, self-rated health and risk factors for cardiovascular disease. Methods: 33 HD patients were included in the study. Inclusion criteria: HD for more than 3 months, age >18 years. Exclusion criteria: Diabetes mellitus, symptomatic cardiovascular disease, musculoskeletal limitations, severe peripheral polyneuropathy, inability to speak Danish or English, dementia or other mental disorders. The patients were randomly assigned to an exercise group (EG, n = 22) or a control group (CG, n = 11). Prior to randomization, baseline testing was performed. The effects were measured by aerobic capacity, ‘2-min stair climbing’, ‘squat test’, self-rated health (SF36), blood pressure and lipids. All tests were carried out by blinded testers. The intervention consisted of 1 h of physical exercise twice a week for 5 months. Results: 20 patients completed the intervention. Attendance was 74% of all sessions. There were no dropouts caused by complications related to the intervention. The EG had a significant increase in aerobic capacity, ‘squat test’ and Physical Function and Physical Component Scale (SF36). No significant changes were observed in any of the parameters in the CG. Conclusion: Physical exercise twice a week for 5 months increases physical function and aerobic capacity in HD patients. An exercise program with only two exercise sessions per week seems easy to implement in clinical practice with high attendance among participants. Further investigation is needed to determine the effects on blood pressure and lipids. There were no medical complications related to the exercise program.

The aim of the study was to assess the validity and reliability of the SF-12 questionnaire in a sample of Iranian patients undergoing hemodialysis.One hundred and forty-four hemodialysis patients were included from dialysis centers in Zanjan, Iran, and were asked to complete the SF-12 and SF-36 questionnaires. An initial test-retest reliability evaluation was performed on a sample of 70 patients from the total group, with a retest interval of 14 days. Reliability was estimated by internal consistency and validity was assessed using known-group comparisons and construct validity on the patient group as a whole. A linear regression analysis was used to assess any variation in the physical component summary and mental component summary scores of the SF-36 with the respective component summary scores of the SF-12. In addition, the factor structure of the questionnaire was extracted by performing a confirmatory factor analysis.Cronbach alpha for physical and mental component summaries were 0.89 and 0.90, respectively. The SF-12 showed a good discriminatory ability between subgroups of patients based on demographic and clinical variables. The confirmatory factor analysis for the original two-factor structure showed a good fit index (chi2 = 23.30, degrees of freedom = 13), goodness-of-fit index = 0.96, and root mean squared error of approximation = 0.079).In general, the SF-12 has good psychometric properties and can be used as a shorter version of the SF-36 questionnaire in future studies involving Iranian patients undergoing hemodialysis.
