Combination of autologous transplantation of G-CSF-mobilized peripheral blood mononuclear cells and Panax notoginseng saponins in the treatment of unreconstructable critical limb ischemia.

The aim of this study is to explore the efficacy and safety of the combination of autologous transplantation of granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood mononuclear cells (PBMNCs) and Panax notoginseng saponins (PNS) in the treatment of unreconstructable critical limb ischemia (CLI).



We performed an open-label, parallel-group, single-center, randomized clinical trial in this study. A total of 52 patients were enrolled and randomly divided into 2 groups (the PBMNC + PNS group and the PBMNC group) in a 1:1 ratio. Evaluation variables, including changes in the ankle-brachial index (ABI) of ischemic limbs, ulcer area, severity of rest pain, transcutaneous oxygen pressure (T(C)PO2), and 6-min walk distance from baseline to week 8 and 16, as well as angiographic scores for new collateral vessel formation at week 16, were used to compare the benefits of these 2 treatment approaches.



After 16 weeks of treatment, improvement in ABI, T(C)PO2, and 6-min walk distance was significantly better in the PBMNC + PNS group. In addition, the combination of PBMNC transplantation and PNS administration yielded a greater reduction in ulcer area and severity of rest pain than did PBMNC transplantation alone. The proportion of patients experiencing any adverse event was similar between both treatment groups. Adverse events caused by PBMNC transplantation or PNS were generally mild and no serious adverse events occurred throughout the entire period of study.



A combination of PNS and PBMNC transplantation appears to be a safe and effective treatment for patients with unreconstructable CLI. This combination may have great potential advantages in comparison with PBMNC transplantation alone and might constitute a novel therapeutic option for unreconstructable CLI.
Quality measures in neurology consult care for epileptic patients.

Epilepsy is one of the most frequently observed diseases in neurology outpatient care.



We analysed our hospital's implementation of the 8 epilepsy quality measures proposed by the American Academy of Neurology: documented seizure types and seizure frequency, aetiology of epilepsy or the epilepsy syndrome, review of EEG, MRI, or CT results, counselling about antiepileptic drug side effects, surgical therapy referral for intractable epilepsy, and counselling about epilepsy-specific safety issues and for women of childbearing age.



In most cases, the first four quality measures were documented correctly. In 66% of the cases, doctors had asked about any adverse drug effects during every visit. Almost all patients with intractable epilepsy had been informed about surgical options or referred to a surgical centre of reference for an evaluation at some point, although referrals usually took place more than 3 years after the initial proposal. Safety issues had been explained to 37% of the patients and less than half of women of childbearing age with epilepsy had received counselling regarding contraception and pregnancy at least once a year.



The care we provide is appropriate according to many of the quality measures, but we must deliver more counselling and information necessary for the care of epileptic patients in different stages of life.
Prospective observational study of dementia and delirium in the acute hospital setting.

Dementia and delirium appear to be common among older patients admitted to acute hospitals, although there are few Australian data regarding these important conditions.



The aim of this study was to determine the prevalence and incidence of dementia and delirium among older patients admitted to acute hospitals in Queensland and to profile these patients.



Prospective observational cohort study (n = 493) of patients aged 70 years and older admitted to general medical, general surgical and orthopaedic wards of four acute hospitals in Queensland between 2008 and 2010. Trained research nurses completed comprehensive geriatric assessments and obtained detailed information about each patient's physical, cognitive and psychosocial functioning using the interRAI Acute Care and other standardised instruments. Nurses also visited patients daily to identify incident delirium. Two physicians independently reviewed patients' medical records and assessments to establish the diagnosis of dementia and/or delirium.



Overall, 29.4% of patients (n = 145) were considered to have cognitive impairment, including 102 (20.7% of the total) who were considered to have dementia. This rate increased to 47.4% in the oldest patients (aged ≥ 90 years). The overall prevalence of delirium at admission was 9.7% (23.5% in patients with dementia), and the rate of incident delirium was 7.6% (14.7% in patients with dementia).



The prevalence of dementia and delirium among older patients admitted to acute hospitals is high and is likely to increase with population aging. It is suggested that hospital design, staffing and processes should be attuned better to meet these patients' needs.
Uric acid as a potential disease modifier in patients with multiple system atrophy.

Recent studies have suggested that mitochondrial dysfunction and oxidative stress play a key role in the pathogenesis of multiple system atrophy.



We evaluated the influence of serum uric acid levels on disease progression in 52 patients with multiple system atrophy using changes in the annualized Unified Multiple System Atrophy Rating Scale scores.



The mean annualized Unified Multiple System Atrophy Rating Scale changes were significantly lower in patients with the highest uric acid quartile compared with those with the lowest quartile (8.4 ± 5.1 vs 20.2 ± 16.0, P = .038). Serum uric acid levels had a significant negative correlation with the annualized Unified Multiple System Atrophy Rating Scale changes (r = -0.40, P = .004). Multiple linear regression analysis showed that only serum uric acid concentration was significantly correlated with the annualized Unified Multiple System Atrophy Rating Scale changes (β = -2.687, P = .011).



These data suggest that serum uric acid may act as a potential disease modifier in multiple system atrophy.
Changes in the anticitrullinated peptide antibody response in relation to therapeutic outcome in early rheumatoid arthritis: results from the SWEFOT trial.

To determine the relationship between changes in antibody levels towards citrullinated peptides derived from different candidate autoantigens and therapeutic outcome in early rheumatoid arthritis (RA).



Baseline and 3-month serum samples from 316 patients with early RA enrolled in the Swedish Farmacotherapy (SWEFOT) trial were analysed for antibodies against cyclic citrullinated peptides (CCP) and citrullinated peptides derived from vimentin (cVim), fibrinogen (cFib) and α-enolase (CEP-1). At 3-month follow-up, methotrexate monotherapy-inadequate responders were randomised to add-on therapy with sulfasalazine and hydroxychloroquine or infliximab. In these patients, anticitrullinated peptide antibodies (ACPA) were also assessed at 12 and 24 months. The proportion of antibody-positive patients and relative changes in antibody levels were compared across ACPA specificities and related to therapeutic response and radiographic progression.



During the 2-year follow-up, the proportion of patients testing positive declined significantly regarding antibodies to cVim, cFib and CEP-1, while anti-CCP antibody occurrence remained stable over time. Turning anti-cVim antibody negative was most common, and anti-cVim antibody seroreversion during the first three months associated with significantly less 2-year radiographic progression compared with patients who remained positive. Median antibody levels of all tested ACPAs declined uniformly during initial methotrexate therapy and following response to add-on therapy, with no significant relation to treatment regimen or radiographic progression.



The influence of early antirheumatic therapy on ACPA seroreversions was markedly different across specificities, and early disappearance of anti-cVim antibodies associated with better radiological outcome. Thus, these data suggest that the disappearance of particular ACPA reactivities may be beneficial in early RA.
Getting the Balance Right: A randomised controlled trial of physiotherapy and Exercise Interventions for ambulatory people with multiple sclerosis

People with Multiple Sclerosis have a life long need for physiotherapy and exercise interventions due to the progressive nature of the disease and their greater risk of the complications of inactivity. The Multiple Sclerosis Society of Ireland run physiotherapy, yoga and exercise classes for their members, however there is little evidence to suggest which form of physical activity optimises outcome for people with the many and varied impairments associated with MS.



This is a multi-centre, single blind, block randomised, controlled trial. Participants will be recruited via the ten regional offices of MS Ireland. Telephone screening will establish eligibility and stratification according to the mobility section of the Guys Neurological Disability Scale. Once a block of people of the same strand in the same geographical region have given consent, participants will be randomised. Strand A will concern individuals with MS who walk independently or use one stick to walk outside. Participants will be randomised to yoga, physiotherapy led exercise class, fitness instructor led exercise class or to a control group who don't change their exercise habits.Strand B will concern individuals with MS who walk with bilateral support or a rollator, they may use a wheelchair for longer distance outdoors. Participants will be randomised to 1:1 Physiotherapist led intervention, group intervention led by Physiotherapist, group yoga intervention or a control group who don't change their exercise habits. Participants will be assessed by physiotherapist who is blind to the group allocation at week 1, week 12 (following 10 weeks intervention or control), and at 12 week follow up. The primary outcome measure for both strands is the Multiple Sclerosis Impact Scale. Secondary outcomes are Modified Fatigue Impact Scale, 6 Minute Walk test, and muscle strength measured with hand held dynamometry. Strand B will also use Berg Balance Test and the Modified Ashworth Scale. Confounding variables such as sensation, coordination, proprioception, range of motion and other impairments will be recorded at initial assessment.



Data analysis will analyse change in each group, and the differences between groups. Sub group analysis may be performed if sufficient numbers are recruited.
Yoga management of breast cancer-related lymphoedema: a randomised controlled pilot-trial

Secondary arm lymphoedema continues to affect at least 20% of women after treatment for breast cancer requiring lifelong professional treatment and self-management. The holistic practice of yoga may offer benefits as an adjunct self-management option. The aim of this small pilot trial was to gain preliminary data to determine the effect of yoga on women with stage one breast cancer-related lymphoedema (BCRL). This paper reports the results for the primary and secondary outcomes.



Participants were randomised, after baseline testing, to receive either an 8-week yoga intervention (n = 15), consisting of a weekly 90-minute teacher-led class and a 40-minute daily session delivered by DVD, or to a usual care wait-listed control group (n = 13). Primary outcome measures were: arm volume of lymphoedema measured by circumference and extra-cellular fluid measured by bioimpedance spectroscopy. Secondary outcome measures were: tissue induration measured by tonometry; levels of sensations, pain, fatigue, and their limiting effects all measured by a visual analogue scale (VAS) and quality of life based on the Lymphoedema Quality of Life Tool (LYMQOL). Measurements were conducted at baseline, week 8 (post-intervention) and week 12 (four weeks after cessation of the intervention).



At week 8, the intervention group had a greater decrease in tissue induration of the affected upper arm compared to the control group (p = 0.050), as well as a greater reduction in the symptom sub-scale for QOL (p = 0.038). There was no difference in arm volume of lymphoedema or extra-cellular fluid between groups at week 8; however, at week 12, arm volume increased more for the intervention group than the control group (p = 0.032).



An 8-week yoga intervention reduced tissue induration of the affected upper arm and decreased the QOL sub-scale of symptoms. Arm volume of lymphoedema and extra-cellular fluid did not increase. These benefits did not last on cessation of the intervention when arm volume of lymphoedema increased. Further research trials with a longer duration, higher levels of lymphoedema and larger numbers are warranted before definitive conclusions can be made.
Feasibility of evidence-based diagnosis and management of heart failure in older people in care: a pilot randomised controlled trial

Many older people in long-term care do not receive evidence-based diagnosis or management for heart failure; it is not known whether this can be achieved for this population. We initiated an onsite heart failure service, compared with 'usual care' with the aim of establishing the feasibility of accurate diagnosis and appropriate management.



A pilot randomised controlled trial which randomised residents from 33 care facilities in North-East England with left ventricular systolic dysfunction (LVSD) to usual care or an onsite heart failure service. The primary outcome was the optimum prescription of angiotensin-converting enzyme inhibitors and beta-adrenergic antagonists at 6 months.



Of 399 echocardiographically-screened residents aged 65-100 years, 30 subjects with LVSD were eligible; 28 (93%) consented and were randomised (HF service: 16; routine care: 12). Groups were similar at baseline; six month follow-up was completed for 25 patients (89%); 3 (11%) patients died. Results for the primary outcome were not statistically significant but there was a consistent pattern of increased drug use and titration to optimum dose in the intervention group (21% compared to 0% receiving routine care, p=0.250). Hospitalisation rates, quality of life and mortality at 6 months were similar between groups.



This study demonstrated the feasibility of an on-site heart failure service for older long-term care populations. Optimisation of medication appeared possible without adversely affecting quality of life; this questions clinicians' concerns about adverse effects in this group. This has international implications for managing such patients. These methods should be replicated in a large-scale study to quantify the scale of benefit.
Translation of a dementia caregiver support program in a health care system--REACH VA.

Based on the National Institute on Aging/National Institute of Nursing Research Resources for Enhancing Alzheimer's Caregiver Health (REACH) randomized controlled trial (REACH II), REACH VA (Department of Veterans Affairs) was the first national clinical translation of a proven behavioral intervention for dementia caregivers, running from September 2007 through August 2009. This article describes the population and outcomes of the REACH VA translation of REACH II into the VA.



Clinical staff members from 24 VA Medical Center Home-Based Primary Care programs in 15 states delivered the intervention to stressed caregivers of patients with dementia. Like REACH II, the 6-month REACH VA intervention, structured through a protocol and individualized through a risk assessment, targeted education, support, and skills training to address caregiving risk areas of safety, social support, problem behaviors, depression, and health through 12 individual in-home and telephone sessions and 5 telephone support group sessions. Staff members of the Memphis VA Medical Center, Memphis, Tennessee, collected data on burden, depression, health and healthy behaviors, caregiving frustrations, social support, dementia-related behaviors, and time spent providing care and on duty.



From baseline to 6 months, caregivers reported significantly decreased burden, depression, impact of depression on daily life, caregiving frustrations, and number of troubling dementia-related behaviors. A 2-hour decrease in hours per day on duty approached significance. Caregivers (96%) believed that the program should be provided by the VA to caregivers.



This clinical translation achieved outcomes similar to the REACH II randomized controlled trial, providing clinically significant benefits for caregivers of a veteran with a progressive dementing disease. This model of caregiver support can inform public policy in providing assistance to caregivers.
Assessment of the accuracy and role of self-recorded blood pressures in the management of hypertension.

Self-recording of the blood pressure by patients away from hospital or office ("home blood pressure") has been advocated as providing a better estimate of "true" blood pressure. The reliability of home blood-pressure recording has been assessed only by standard indirect methods which themselves are subject to considerable error and variability. The accuracy of self-recorded blood pressures was therefore assessed in 57 patients with essential hypertension by comparison with simultaneous measurements of clinic blood pressures and with intra-arterial blood pressures recorded at home and at hospital. Home systolic blood pressures showed good agreement with clinic and intra-arterial pressures, but home diastolic blood pressures overestimated intra-arterial pressures, as did clinic diastolic pressures. The clinic and home diastolic pressures showed good agreement. There was considerable variability in individual differences comparing the indirect and intra-arterial methods, though the two indirect methods showed much closer agreement. This study suggests that home blood pressures are as accurate as clinic readings but may be recorded more frequently and thus provide more useful information. Neither is likely to approximate the intra-arterial blood pressure.
Long-term evaluation of home-based pulmonary rehabilitation in patients with COPD.

Personalized, global pulmonary rehabilitation (PR) management of patients with COPD is effective, regardless of the place in which this rehabilitation is provided. The objective of this retrospective observational study was to study the long-term outcome of exercise capacity and quality of life during management of patients with COPD treated by home-based PR.



Home-based PR was administered to 211 patients with COPD (mean age, 62.3±11.1 years; mean forced expiratory volume in 1 second, 41.5%±17.7%). Home-based PR was chosen because of the distance of the patient's home from the PR center and the patient's preference. Each patient was individually managed by a team member once a week for 8 weeks with unsupervised continuation of physical exercises on the other days of the week according to an individual action plan. Exercise conditioning, therapeutic patient education, and self-management were included in the PR program. The home assessment comprised evaluation of the patient's exercise capacity by a 6-minute stepper test, Timed Up and Go test, ten times sit-to-stand test, Hospital Anxiety and Depression score, and quality of life (Visual Simplified Respiratory Questionnaire, VQ11, Maugeri Respiratory Failure 28).



No incidents or accidents were observed during the course of home-based PR. The 6-minute stepper test was significantly improved after completion of the program, at 6 months and 12 months, whereas the Timed Up and Go and ten times sit-to-stand test were improved after PR and at 6 months but not at 12 months. Hospital Anxiety and Depression and quality of life scores improved after PR, and this improvement persisted at 6 months and 12 months.



Home-based PR for unselected patients with COPD is effective in the short term, and this effectiveness is maintained in the medium term (6 months) and long term (12 months). Home-based PR is an alternative to outpatient management provided all activities, such as exercise conditioning, therapeutic education, and self-management are performed.
Lipid-induced insulin resistance is associated with an impaired skeletal muscle protein synthetic response to amino acid ingestion in healthy young men.

The ability to maintain skeletal muscle mass appears to be impaired in insulin-resistant conditions, such as type 2 diabetes, that are characterized by muscle lipid accumulation. The current study investigated the effect of acutely increasing lipid availability on muscle protein synthesis. Seven healthy young male volunteers underwent a 7-h intravenous infusion of l-[ring-(2)H5]phenylalanine on two randomized occasions combined with 0.9% saline or 10% Intralipid at 100 mL/h. After a 4-h "basal" period, a 21-g bolus of amino acids was administered and a 3-h hyperinsulinemic-euglycemic clamp was commenced ("fed" period). Muscle biopsy specimens were obtained from the vastus lateralis at 1.5, 4, and 7 h. Lipid infusion reduced fed whole-body glucose disposal by 20%. Furthermore, whereas the mixed muscle fractional synthetic rate increased from the basal to the fed period during saline infusion by 2.2-fold, no change occurred during lipid infusion, despite similar circulating insulin and leucine concentrations. This "anabolic resistance" to insulin and amino acids with lipid infusion was associated with a complete suppression of muscle 4E-BP1 phosphorylation. We propose that increased muscle lipid availability may contribute to anabolic resistance in insulin-resistant conditions by impairing translation initiation.
Efficacy of pulsed electromagnetic field therapy in healing of pressure ulcers: A randomized control trial.

Pressure ulcers are one of the most common complications in health care settings. Still there are no optimal protocols to manage the pressure ulcers.



To assess the effectiveness of pulsed electromagnetic field therapy (PEMF) in healing of pressure ulcers in patients with neurological disorders.



Randomized double blind control trial.



Neurological rehabilitation department in a university research hospital.



Twelve patients (M:F, 9:3) having neurological disorders, with age between 12-50 years (mean 30.166 +/- 11.32 yrs) and 24 pressure ulcers.



Six patients with 13 ulcers received PEMF therapy and the remaining 6 patients with 11 ulcers received sham treatment, for 30 sessions (45 minutes each) using the equipment 'Pulsatron'. The frequency of PEMF was set at 1 Hz with sine waves and current intensity of 30 mili ampere. Whole body exposure was given in both the groups.



Bates-Jensen wound assessment tool (BJWAT) score was used as main outcome measure and scores at the end of session were compared with initial scores and analyzed. Similarly National Pressure Ulcer Advisory Panel (NPUAP) scores were compared and analyzed as secondary outcome measure.



Thirteen ulcers were in stage IV and 11 were in stage III at the start of the study. Significant healing of ulcers was noted, BJWAT scores, in both the treatment and sham groups (P < 0.001 and 0.003 respectively) at the completion of the study. However, when comparing between the groups, healing was not significant (P = 0.361). Similarly trend was noted with NPUAP scores with no significant difference between the treatment and sham groups (P = 0.649) at the completion of study.



No significant difference in pressure ulcer healing was observed between PEMF treatment and sham group in this study.
