Objectives To compare high-level mobility in individuals with chronic moderate-to-severe traumatic brain injury (TBI) with matched healthy controls, and to investigate whether clinical variables and magnetic resonance imaging (MRI) findings in the acute phase can predict high-level motor performance in the chronic phase. Design A longitudinal follow-up study. Setting A level 1 trauma center. Participants Individuals (N=136) with chronic TBI (n=65) and healthy matched peers (n=71). Interventions Not applicable. Main Outcome Measures High-Level Mobility Assessment Tool (HiMAT) and the revised version of the HiMAT performed at a mean of 2.8 years (range, 1.5–5.4y) after injury. Results Participants with chronic TBI had a mean HiMAT score of 42.7 (95% confidence interval [CI], 40.2–45.2) compared with 47.7 (95% CI, 46.1–49.2) in the control group ( P <.01). Group differences were also evident using the revised HiMAT ( P <.01). Acute-phase clinical variables and MRI findings explained 58.8% of the variance in the HiMAT score ( P <.001) and 59.9% in the revised HiMAT score ( P <.001). Lower HiMAT scores were associated with female sex ( P =.031), higher age at injury ( P <.001), motor vehicle collisions ( P =.030), and posttraumatic amnesia >7 days ( P =.048). There was a tendency toward an association between lower scores and diffuse axonal injury in the brainstem ( P =.075). Conclusions High-level mobility was reduced in participants with chronic, either moderate or severe TBI compared with matched peers. Clinical variables in the acute phase were significantly associated with high-level mobility performance in participants with TBI, but the role of early MRI findings needs to be further investigated. The findings of this study suggest that the clinical variables in the acute phase may be useful in predicting high-level mobility outcome in the chronic phase. [ABSTRACT FROM AUTHOR]

Abstract: Standardized scales to evaluate qualities of trunk movements in children with dysfunction are sparse. An examination of the reliability of scales that may be useful in the clinic is important. The aim of this study was to examine the reliability of the Trunk Impairment Scale (TIS) for children with cerebral palsy (CP). Standardized scales are useful for treatment planning and evaluation. This was an intra- and inter-observer reliability study. Video recordings of 25 children, 20 with CP and 5 with no motor impairment, in the age group 5–12 years of age, were analyzed by three observers on two occasions. Intraclass correlation coefficients (ICC [1,1] and [3,1]) with 95% confidence intervals, standard error of measurement, kappa values and percent agreement, and Bland–Altman Plots were calculated. The relative reliability (intra- and inter-observer reliability) was very high for the total score and subscale score of the TIS: ICC [1,1] and [3,1] varied between .94 and 1.00. Kappa values for the items ranged from .45 to 1.00. The absolute reliability values for the parameters are reported. The Bland–Altman analysis showed consistency of scores. This study indicates that TIS is a reliable measure of trunk control for children, 5–12 years of age, with CP. [Copyright &y& Elsevier]

Background: Phosphorylation is a key regulatory event in controlling the function of the cardiac gap junction protein connexin43 (Cx43). Three new phosphorylation sites (S296, S297, S306) have been identified on Cx43; two of these sites (S297 and S306) are dephosphorylated during ischemia. The functional significance of these new sites is currently unknown. Objective: The purpose of this study was to examine the role of S296, S297, and S306 in the regulation of electrical intercellular communication. Methods: To mimic constitutive dephosphorylation, serine was mutated to alanine at the three sites and expressed in HeLa cells. Electrical coupling and single channel measurements were performed by double patch clamp. Protein expression levels were assayed by western blotting, localization of Cx43, and phosphorylation of S306 by immunolabeling. Free hemichannels were assessed by biotinylation. Results: Macroscopic conductance in cells expressing S306A was reduced to 57% compared to wild type (WT), whereas coupling was not significantly changed in cells expressing either S296A or S297A. S306A-expressing cells displayed similar protein and free hemichannel abundance compared to WT Cx43, whereas the fractional area of plaques in cell-to-cell interfaces was increased. However, single channel measurements showed a WT Cx43 main state conductance of 119 pS, whereas the main state conductance of S306A channels was reduced to 95 pS. Furthermore, channel gating was affected in S306A channels. Conclusion: Lack of phosphorylation at serine 306 results in reduced coupling, which can be explained by reduced single channel conductance. We suggest that dephosphorylation of S306 partly explains the electrical uncoupling seen in myocardial ischemia. [Copyright &y& Elsevier]

• Patients with COPD in exacerbation were mentally and physically burdened on admission. • The patients experienced a communication of varied quality and empathy. • Addressing HCPs' communication skills, attitudes and staff professionalism to accommodate a caring approach to a burdened group of patients is essential. Chronic obstructive pulmonary disease causes significant burdens for patients. To secure safe care and treatment in the first part of the patient trajectory, it is essential to explore patients' experiences during admission in the acute phase following an exacerbation due to COPD. Thirteen semi-structured interviews were performed, using Kvale and Brinkman's meaning condensation as an analytical approach. The findings are illustrated in four themes: A burdened patient group; the urgent need for air; to be in a cross field between chaos, waiting time and uncertainty; and communication as the lifeline. Patients were distressed due to shortness of breath and anxiety in the busy setting of the emergency department, and the analysis showed that breathing was the most important and urgent issue when the patients were acutely admitted. This study contributes to the evidence base on how the first part of the trajectory affects patients' ability to master their situation and their overall well-being. [ABSTRACT FROM AUTHOR]

Abstract: Background: Inflammatory biomarkers are reported as risk factors for atrial fibrillation (AF), but their impact is uncertain. Objective: We investigated the associations between inflammatory biomarkers and future AF in a large general cohort. Methods: Available markers were white blood cells (WBCs) with subgroups, fibrinogen, high-sensitivity C-reactive protein (hs-CRP), and osteoprotegerin (OPG). A total of 6315 men and women from a population survey in Tromsø, Norway in 1994 to 1995 were followed for a mean of 10.9 years. Mean age at baseline was 60 years. Measurements of height, weight, blood pressure, heart rate, total cholesterol, high-density lipoprotein (HDL) cholesterol, WBC count, and information on diabetes, angina, myocardial infarction, and antihypertensive treatment, were obtained at baseline. Fibrinogen, hs-CRP, and OPG were obtained at a follow-up visit. The outcome measure was first-ever AF, documented on an electrocardiogram. The Cox proportional hazards regression model was used to estimate hazard ratios of AF. Results: In the multivariable analysis, adjusted for traditional cardiovascular risk factors and other inflammatory biomarkers, hs-CRP was associated with AF in men only (hazard ratio = 1.14 for a 1 SD increase; 95% CI, 1.02–1.28). There was a significant increase in AF across quartiles of WBCs in men (P = 0.007) and in the total study population (P = 0.004). OPG was associated with AF in patients free of coronary heart disease at baseline. Fibrinogen and subgroups of WBCs showed no significant association with AF. Conclusion: This population-based cohort study showed that hs-CRP was independently associated with AF in men, but apparently not in women, and that patients with WBCs in the upper quartile had increased risk of AF.

Low-grade inflammation is associated with fractures, while the relationship between inflammation and bone mineral density (BMD) is less clear. Moreover, any gender differences in the sensitivity to inflammation are still poorly elucidated. We therefore tested the hypothesis that high-sensitivity C-reactive protein (CRP) is an independent risk factor for low BMD and non-vertebral fractures, in both genders, and whether there are gender differences in these associations. CRP levels and BMD at the total hip and femoral neck were measured in 1902 women and 1648 men between 55 and 74 years of age, at baseline in the Tromsø Study, Norway, in 2001–2002. Non-vertebral fractures were registered from hospital X-ray archives during an average of 7.2 years follow-up. Linear regression analyses were used for CRP association with BMD and Cox proportional hazards model for fracture prediction by CRP. During 25 595 person-years follow-up, 366 (19%) women and 126 (8%) men suffered a non-vertebral fracture. There was no association between CRP and BMD in women, but an inverse association in men ( p = 0.001) after adjustment for age and body mass index. Each standard deviation (SD) increase in log-CRP was associated with an increased risk for non-vertebral fracture by 13% in women and 22% in men (hazard ratios (HRs) 1.13, 95% confidence interval (CI) 1.02–1.26, p = 0.026 and 1.22, 95% CI = 1.00–1.48, p = 0.046, respectively). After adjustment for BMD and other risk factors, women with CRP in the upper tertile exhibited 39% higher risk for fracture than those in the lowest tertile of CRP (HR = 1.39, 95% CI = 1.06–1.83, p = 0.017), while men in the upper tertile exhibited 80% higher risk (HR = 1.80, 95% CI = 1.10–2.94, p = 0.019). In summary, CRP was not associated with BMD in women but inversely associated in men, and predicted fractures in both genders. We infer that inflammation influence fracture risk in both women and men, although the biological mechanisms may differ between the genders. [ABSTRACT FROM AUTHOR]

Abstract: Background: The ratio between urinary albumin concentration (UAC) and urinary creatinine concentration (UCC) is widely used to estimate renal involvement. We examined how UAC and UCC associate with each other, with other risk factors, and with diabetic complications in a population-based sample of Type 2 diabetic patients. Methods: A freshly voided morning urine specimen was provided by 1284 consecutive, newly diagnosed diabetic patients aged 40 years or over in general practice. Albumin was measured by a polyethyleneglycol radioimmunoassay and creatinine by a modified Jaffe method. Results: In a multivariate model including UAC, UCC, age, sex, HbA1c, and urinary glucose concentration, UAC increased with both age (P=.042) and HbA1c (P=.014), while UCC decreased (P<.001 and P<.001, respectively). In two regression models, the prevalence of diabetic retinopathy (P<.001) and relatively high resting heart rate (P<.001) increased with increasing UAC but decreased with increasing UCC (P=.002 and P=.005, respectively). Conclusion: The use of albumin/creatinine ratio (ACR) may introduce bias of unpredictable size and direction in comparisons of ACR with variables that are associated with UCC in their own right. In daily clinical practice, renal involvement in the individual patient can be estimated reliably with UAC or ACR measured in a freshly voided morning urine specimen, especially when considered together. However, the associations of the combined measure ACR should be interpreted with great caution in clinical and epidemiological research. [Copyright &y& Elsevier]
