Comparison of walking energy cost between an anterior and a posterior ankle-foot orthosis in people with foot drop.

To compare walking energy cost between an anterior and a posterior ankle-foot orthosis in people with foot drop.Within-group comparisons.Twenty-three adults (14 women, 9 men; mean age 56.8 years (standard deviation 15.4)) with foot drop.PARTICIPANTS were asked to walk for 5 min at their self-selected walking speed under 3 conditions: (i) with shoes only; (ii) with a posterior ankle-foot orthosis; (iii) with an anterior ankle-foot orthosis. Spatio-temporal gait para-meters (speed, step length and step frequency) and walking energy cost per unit of distance were assessed for each walking condition. A visual analogue scale was used to quantify participants' level of perceived comfort for the 2 orthosis.Gait spatio-temporal parameters were higher with anterior ankle-foot orthoses than with posterior ankle-foot orthoses or shoes only. Walking energy cost per unit of distance was lower with anterior than posterior ankle-foot orthosis or shoes only ((mean ± standard error) 3.53 ± 1.00 vs 3.94 ± 1.27 and 3.98 ± 1.53 J·kg-1·m-1 respectively; p  0.05) and level of perceived comfort was higher with anterior ((mean ± standard error) 8.00 ± 1.32) than with posterior ankle-foot orthosis ((mean ± standard error) 4.52 ± 2.57; p  0.05).In people with foot drop the use of anterior ankle-foot orthoses resulted in lower energy costs of walking and higher levels of perceived comfort compared with posterior ankle-foot orthoses. Anterior ankle-foot orthoses may enable people with foot drop to walk further with less physical effort than posterior ankle-foot orthoses

Diabetic education in nursing: A Rodgers' evolutionary concept analysis

Aim: This concept analysis aims to clarify the concept of diabetic education in nursing to provide guidance for the further conceptualization and clarification of diabetic education in nursing.Background: Patient education is a fundamental component of diabetes care. Nurses have taken up a major role in educating people with diabetes to manage their conditions. However, the exact meaning of diabetic education in nursing remains challenging.Design: Rodgers' evolutionary method of concept analysis was performed to explore the concept of diabetic education in nursing.Data Source: We conducted a literature search on Cumulative Index to Nursing and Allied Health Literature (CINAHL). MedLine, and Psyclnfo for works published until October 2020 using "patient education," "diabetes," and "nursing" as key terms.Results: The concept analysis revealed that key attributes of diabetic education in nursing include patient-centered and interactive approaches, planning, and problem solving. Antecedents related to individuals with diabetes are their backgrounds. needs, and motivations, while the antecedents related to nurses are experience and attitude. Finally, three different consequences of the concept emerged: an increase in knowledge and skills, a behavioral change, and the improvement of clinical outcomes

Ultrasound tissue characterization detectspreclinical myocardial structural changes inchildren affected by Duchenne muscular dystrophy

AbstractObjectivesOur goal was to identify early changes in myocardial physical properties in children with Duchenne muscular dystrophy (DMDch).BackgroundDuchenne muscular dystrophy (DMD) is caused by the absence of dystrophin, which triggers complex molecular and biological events in skeletal and cardiac muscle tissues. Although about 30% of patients display overt signs of cardiomyopathy in the late stage of the disease, it is unknown whether changes in myocardial physical properties can be detected in the early (preclinical) stages of the disease.MethodsWe performed an ultrasonic tissue characterization (UTC) analysis of myocardium in DMDch with normal systolic myocardial function and no signs of cardiomyopathy. Both the cyclic variation of integrated backscatter (cvIBS) and the calibrated integrated backscatter (cIBS) were assessed in 8 myocardial regions of 20 DMDch, age 7 ± 2 years (range 4 to 10 years), and in 20 age-matched healthy controls.ResultsWe found large differences in the UTC data between DMDch and controls; the mean value of cvIBS was 4.4 ± 1.5 dB versus 8.8 ± 0.8 dB, whereas the mean value of cIBS was 36.4 ± 7.1 dB versus 26.9 ± 2.0 dB (p < 10−6for both). In DMDch, all eight sampled segments showed cIBS mean values to be significantly higher and cvIBS mean values to be significantly lower than those in the controls. Finally, interindividual differences were greater in DMDch than in controls for both parameters.ConclusionsThe myocardium in DMDch displays UTC features different from those in healthy controls. These results show that lack of dystrophin is commonly associated with changes in myocardial features well before the onset of changes of systolic function and overt cardiomyopathy

Clinical features and outcomes of elderly hospitalised patients with chronic obstructive pulmonary disease, heart failure or both

Background and objective: Chronic obstructive pulmonary disease (COPD) and heart failure (HF) mutually increase the risk of being present in the same patient, especially if older. Whether or not this coexistence may be associated with a worse prognosis is debated. Therefore, employing data derived from the REPOSI register, we evaluated the clinical features and outcomes in a population of elderly patients admitted to internal medicine wards and having COPD, HF or COPD + HF. Methods: We measured socio-demographic and anthropometric characteristics, severity and prevalence of comorbidities, clinical and laboratory features during hospitalization, mood disorders, functional independence, drug prescriptions and discharge destination. The primary study outcome was the risk of death. Results: We considered 2,343 elderly hospitalized patients (median age 81 years), of whom 1,154 (49%) had COPD, 813 (35%) HF, and 376 (16%) COPD + HF. Patients with COPD + HF had different characteristics than those with COPD or HF, such as a higher prevalence of previous hospitalizations, comorbidities (especially chronic kidney disease), higher respiratory rate at admission and number of prescribed drugs. Patients with COPD + HF (hazard ratio HR 1.74, 95% confidence intervals CI 1.16-2.61) and patients with dementia (HR 1.75, 95% CI 1.06-2.90) had a higher risk of death at one year. The Kaplan-Meier curves showed a higher mortality risk in the group of patients with COPD + HF for all causes (p = 0.010), respiratory causes (p = 0.006), cardiovascular causes (p = 0.046) and respiratory plus cardiovascular causes (p = 0.009). Conclusion: In this real-life cohort of hospitalized elderly patients, the coexistence of COPD and HF significantly worsened prognosis at one year. This finding may help to better define the care needs of this population

Beta-Blocker Use in Older Hospitalized Patients Affected by Heart Failure and Chronic Obstructive Pulmonary Disease: An Italian Survey From the REPOSI Register

Beta (β)-blockers (BB) are useful in reducing morbidity and mortality in patients with heart failure (HF) and concomitant chronic obstructive pulmonary disease (COPD). Nevertheless, the use of BBs could induce bronchoconstriction due to β2-blockade. For this reason, both the ESC and GOLD guidelines strongly suggest the use of selective β1-BB in patients with HF and COPD. However, low adherence to guidelines was observed in multiple clinical settings. The aim of the study was to investigate the BBs use in older patients affected by HF and COPD, recorded in the REPOSI register. Of 942 patients affected by HF, 47.1% were treated with BBs. The use of BBs was significantly lower in patients with HF and COPD than in patients affected by HF alone, both at admission and at discharge (admission, 36.9% vs. 51.3%; discharge, 38.0% vs. 51.7%). In addition, no further BB users were found at discharge. The probability to being treated with a BB was significantly lower in patients with HF also affected by COPD (adj. OR, 95% CI: 0.50, 0.37-0.67), while the diagnosis of COPD was not associated with the choice of selective β1-BB (adj. OR, 95% CI: 1.33, 0.76-2.34). Despite clear recommendations by clinical guidelines, a significant underuse of BBs was also observed after hospital discharge. In COPD affected patients, physicians unreasonably reject BBs use, rather than choosing a β1-BB. The expected improvement of the BB prescriptions after hospitalization was not observed. A multidisciplinary approach among hospital physicians, general practitioners, and pharmacologists should be carried out for better drug management and adherence to guideline recommendations
