Re-evaluation of websites from burn centers in Austria,Germany and Switzerland

Introduction

Websites serve as information and communication platforms; hence, they are important tools for the self-promotion of hospitals. In 2010, Selig et al. evaluated the online presence of burn centers in Germany, Austria, and Switzerland based on 37 quality criteria. This study aimed to re-evaluate these websites to assess their development over the past 6.5 years.

Measurement Properties of the Modified Spinal Function Sort (M-SFS): Is It Reliable and Valid in Workers with Chronic Musculoskeletal Pain?

Purpose To analyze the reliability and validity of a picture-based questionnaire, the Modified Spinal Function Sort (M-SFS). Methods Sixty-two injured workers with chronic musculoskeletal disorders (MSD) were recruited from two work rehabilitation centers. Internal consistency was assessed by Cronbach’s alpha. Construct validity was tested based on four a priori hypotheses. Structural validity was measured with principal component analysis (PCA). Test–retest reliability and agreement was evaluated using intraclass correlation coefficient (ICC) and measurement error with the limits of agreement (LoA). Results Total score of the M-SFS was 54.4 (SD 16.4) and 56.1 (16.4) for test and retest, respectively. Item distribution showed no ceiling effects. Cronbach’s alpha was 0.94 and 0.95 for test and retest, respectively. PCA showed the presence of four components explaining a total of 74% of the variance. Item communalities were >0.6 in 17 out of 20 items. ICC was 0.90, LoA was ±12.6/16.2 points. The correlations between the M-SFS were 0.89 with the original SFS, 0.49 with the Pain Disability Index, ?0.37 and ?0.33 with the Numeric Rating Scale for actual pain, ?0.52 for selfreported disability due to chronic low back pain, and 0.50, 0.56–0.59 with three distinct lifting tests. No a priori defined hypothesis for construct validity was rejected. Conclusions The M-SFS allows reliable and valid assessment of perceived self-efficacy for work-related tasks and can be recommended for use in patients with chronic MSD. Further research should investigate the proposed M-SFS score of <56 for its predictive validity for non-return to work.     

Growth and Aging of Proximal Femoral Bone: A Study With Women Spanning Three Generations

Osteoporotic hip fracture is a serious clinical event associated with high morbidity and mortality. Understanding femoral growth patterns is important for promoting bone health in the young and preventing fractures in later life. In this study, growth patterns of areal bone mineral density (aBMD) and geometric properties of the proximal femur were measured by dual‐energy X‐ray absorptiometry. They were studied in 251 girls from premenarche (11.2 ± 0.7 years) to late adolescence (18.3 ± 1.1 years) and compared with their premenopausal mothers (n = 128, aged 44.9 ± 4.1 years) and postmenopausal grandmothers (n = 128, aged 70.0 ± 6.3 years). Hip axis length (HAL) was the first to reach peak growth velocity (?10.5 months before menarche), followed by neck diameter (ND) and neck cross‐sectional area (CSA), (?7.1 and ?4.1 months before menarche, respectively). Both neck‐shaft angle (NSA) and aBMD of neck and total hip peaked at menarche. At 18 years (7‐year follow‐up), girls already had higher femoral neck aBMD but similar HAL and NSA compared with their mothers. Grandmothers had the longest HAL, narrowest NSA, widest ND but lowest aBMD and CSA. Hip strength index (HSI), an index of femoral neck strength during a fall, dropped rapidly after menarche in girls but thereafter remained relatively constant. Grandmothers had lower HSI than either mothers or girls. In conclusion, differences in proximal femoral bone mass and structure in adulthood are largely established before menarche, indicating that heritable factors are responsible for most of the individual variance. The development of geometric properties precedes aBMD in puberty, resulting in relatively constant hip strength after menarche. This asynchronous growth leads to adaptation of bone strength to the imposed loads, avoiding fractures in a biologically efficient manner. Both deterioration of aBMD and inadequate compensatory change in bone geometry after menopause contribute to the increased fracture risk later in life. © 2014 American Society for Bone and Mineral Research.     

Getting off on the right (or left) foot: perceiving by means of a rod attached to the preferred or non-preferred foot

Behavior is typically organized in terms of a goal one intends to achieve rather than in terms of the anatomical components used in doing so. Similarly, perceptual behavior is typically organized in terms of a property one intends to perceive rather than in terms of the anatomical components used in doing so. Such task-specificity and anatomical independence are manifest in perception of properties of wielded objects. We investigated whether these properties are also manifest in perception of properties by means of wielded objects. Blindfolded participants explored an inclined surface with a rod attached to their preferred or non-preferred foot and reported whether they would be able to stand on that surface. Perception reflected action capabilities, but was unaffected by foot used, highlighting the haptic system as a smart perceptual device.     

Motives for and barriers to physical activity in twin pairs discordant for leisure time physical activity for 30 years

Long-term persistent physical activity is important in the prevention of chronic diseases, but a large number of people do not participate in physical activity to obtain health benefits. The purpose of this study was to examine the motives and perceived barriers to long-term engagement in leisure time physical activity. Same-sex twin pairs (N=16, mean age 60) discordant for physical activity over 30 years were identified from the Finnish Twin Cohort. We evaluated participants' physical activity motivation with the 73-item Recreational Exercise Motivation Measure and assessed barriers to physical activity with a 25-item questionnaire. The characteristics of physical activity motivation and perceived barriers between the active and inactive co-twins were analysed using paired tests. Motives related to the sub-dimensions of enjoyment and physical fitness and psychological state were the most important reasons for participation in physical activity among all the twin individuals analysed. The sub-dimensions mastery (p=0.018, Cohen's d=0.76), physical fitness (p=0.029, Cohen's d=0.69), and psychological state (p=0.039, Cohen's d=0.65) differed significantly between active and inactive co-twins. More than half of the participants reported no reasons for not being physically active. If reasons existed, participation in physical activity was deterred mostly by pain and various health problems. This study found no differences in perceived barriers between active and inactive co-twins. We conclude from our results that the main factors promoting persistent leisure time physical activity were participants' wish to improve or maintain their physical skills or techniques, a feeling that exercise would improve their mental and physical health and that they found the activity enjoyable. This study helps us understand the importance of the role of motives and the minor role of perceived barriers for engagement in persistent physical activity.     

Clinical characteristics and cytokine biomarkers in patients with chronic graft-vs-host disease persisting seven or more years after diagnosis

Chronic graft-versus-host disease (cGVHD) is the leading late complication after allogeneic hematopoietic stem cell transplantation (HSCT). Many patients receive multiple lines of systemic therapy until cGVHD resolves, but about 15% remain on systemic treatment for more than 7 years after cGVHD diagnosis. This study describes the clinical and biological factors of patients who present with cGVHD persisting for ≥7 years (persistent cGVHD). Patients with persistent cGVHD (n = 38) and those with cGVHD for <1 year (early cGVHD) (n = 83) were enrolled in a prospective cross-sectional natural history study. Patients in the persistent cGVHD group were a median of 10.2 years from cGVHD diagnosis (range 7-27 years). Fifty-eight percent of persistent cGVHD patients (22/38) were receiving systemic immunosuppression, compared to 88% (73/83) in the early cGVHD group. In multivariable analysis, bone marrow (BM) stem cell source, presence of ENA autoantibodies, higher NIH lung score, higher platelet counts, and higher IgA levels were significantly associated with persistent cGVHD. A high sensitivity panel of serum biomarkers including seven cytokines diagnostic for cGVHD was analyzed and showed significantly lower levels of BAFF and CXCL10 in patients with persistent cGVHD. In conclusion, standardly accepted clinical measures of disease severity may not accurately reflect disease activity in patients with persistent cGVHD. However, many patients with persistent cGVHD are still receiving systemic immunosuppression despite lacking evidence of disease activity. Development of reliable clinical biomarkers of cGVHD activity may help guide future systemic treatments.     

Duodenum-preserving versus pylorus-preserving pancreatic head resection for benign and premalignant lesions

Background/purpose

Pylorus-preserving pancreaticoduodenectomy (PPPD) is the treatment of choice for benign or premalignant pancreatic head lesions. Duodenum-preserving pancreatic head resection (DPPHR) has been reported in only 132 patients. This study aimed to compare the long-term results of DPPHR and PPPD.

Methods

Patients who underwent DPPHR or PPPD for benign or borderline disease between 1991 and 2008 were followed up until December 2009 or their death. Endocrine and exocrine pancreatic functions were evaluated at their last follow-up.

Results

Twenty-seven patients underwent DPPHR (Group 1) and 37 PPPD (Group 2). They were followed for a mean of 100 and 135?months, respectively. Group 1 had a higher complication rate (81.5 vs. 40.5%) and pancreatic fistula rate (40.1 vs. 18.9%). Hospital mortality was 0 and 2.7%, respectively. Two patients died 3.3 and 97?months after DPPHR. Significantly more Group 2 patients needed medical treatment for benign cholangitis (P?<?0.0001). Insulin-dependent diabetes mellitus was observed in six Group 1 and 15 Group 2 patients (P?=?0.077). Ten Group 1 and 21 Group 2 patients are taking pancreatic enzymes (P?=?0.003).

Conclusions

DPPHR for benign or premalignant lesions is a difficult procedure with a higher complication rate than PPPD, but was without mortality. Preserving the entire duodenum and a normal biliary tree allows better long-term results.     

The Influence of Etiologic Factors on Clinical Outcome in Patients with Peptic Ulcer Bleeding

Background

Peptic ulcer bleeding remains an important cause of morbidity and mortality.

Aim

The aim of this study was to evaluate the prevalence of non-steroidal anti-inflammatory drugs (NSAID) use, Helicobacter pylori infection and non-H. pylori?Cnon-NSAIDs causes of peptic ulcer bleeding and to identify the predictive factors influencing the rebleeding rate and in-hospital mortality in patients with bleeding peptic ulcer.

Methods

A total of 1,530 patients with endoscopically confirmed peptic ulcer bleeding were evaluated consecutively between January 2005 and December 2009. The 30-day mortality and clinical outcome were related to patient??s demographic data, endoscopic and clinical characteristics.

Results

The age-standardized 1-year cumulative incidence for peptic ulcer bleeding was 40.4 cases/100,000 people. The proportion of patients over 65?years increased from 45.7?% in 2005 to 61.4?% in 2009 (p?=?0.007). Overall 30-day mortality rate was 4.6?%, not significantly different for conservatively and surgically treated patients (4.9 vs. 4.1?%, p?=?0.87). Mortality was significantly higher in patients over 65?years of age and those with in-hospital bleeding recurrence. Patients with non-H. pylori?Cnon-NSAID idiopathic ulcers had significantly higher 30-day mortality rate than those with H. pylori ulcers and NSAID?CH. pylori ulcers (7.1 vs. 0 vs. 0.8?%, p?=?0.001 and p?=?0.007, respectively). There was no statistically significant difference between patients with NSAID ulcers and non-H. pylori?Cnon-NSAID idiopathic ulcers in terms of 30-day mortality rate (5.3 vs. 7.1?%, p?=?0.445).

Conclusion

The incidence of peptic ulcer bleeding has not changed over a 5-year observational period. The overall 30-day mortality was positively correlated to older age, underlying comorbid illnesses, in-hospital bleeding recurrence and the absence of H. pylori infection.
