Patients’ experiences of physical limitations in daily life activities when suffering from chronic heart failure; a phenomenographic analysis The aim of the study was to describe how patients suffering from chronic heart failure conceived their physical limitations in daily life activities. An explorative and qualitative design with a phenomenographic approach was chosen, a total of 15 patients were interviewed. The findings indicate that participants perceived a variety of structural aspects pertaining to physical limitations in activities of daily life which resulted in four referential aspects. Need of finding practical solutions in daily life focused on how life had to be changed and other ways of performing activities of daily life had to be invented. Having realistic expectations about the future was characterised by belief that the future itself would be marked by change in physical functioning, but an incentive to maintain functions and activities ensured good quality of or even increased capacity in daily life. Not believing in one’s own ability included the perception of having no opportunity to improve ability to perform activities of daily life. There were perceptions of undesired passivity, undefined fear of straining themselves or performing activities that could endanger their health in addition to uncertainty about the future. In Losing one’s social role in daily life, participants described losing their social network and their position in society and family because of limited physical capacity. A lack of important issues, mental and physical, occurred when physical capacity was lost. In conclusion, patients suffering from chronic heart failure found new solutions to manage activities in daily life, including willingness to change focus and identify other ways of doing important things. Patients had an incentive to maintain functions and activities to ensure a good quality of and strengthen their physical capacity in daily life. Inability to trust in their physical capacity in combination with experienced limitations in daily life prevented patients from attempting to increase activities.     

Tumor Prognostic Factors and the Challenge of Developing Predictive Factors

Histopathologic classification has been widely used to type and grade primary brain tumors. However, the diverse behavior of primary brain tumors has made prognostic determinations based purely on clinical and histopathologic variables difficult. Recent advances in the molecular genetics of brain tumors have helped to explain the witnessed heterogeneity regarding response to treatment, time to progression, and overall survival. Additionally, there has been interest in identifying predictive factors to help direct patients to therapeutic interventions specific to their tumor and patient biology. Further identification of both prognostic and predictive biomarkers will make possible better patient stratification and individualization of treatment.

Experiences of the new role of advanced practice nurses in Swedish primary health care—A qualitative study
The aim of this study was to investigate and describe the experiences of the first advanced practice nurses (APNs), a new profession for Swedish health care, and of their supervising general practitioners (GPs), regarding the new role and scope of practice of APNs in primary health care. Individual interviews were conducted with the four first APNs and one focus group interview was conducted with five supervising physicians. The material was transcribed verbatim and analysed using latent content analysis. The respondents expressed confidence and trust in the new role of APNs. Some opposition to this new role from the GPs and other colleagues was observed, but was nonetheless overcome. The experiences of the APN role indicate that the new role is clearly demarcated from the role of physicians. The APNs were considered an extra resource for both the GPs and other nurses, which contributed to an increased availability of care for patients. The APN role requires an explicit definition and demarcation in relation to responsibility and roles among colleagues. Further development of the APN role presupposes the right to prescribe medication and order treatments, as well as an evaluation of patient, organizational and inter-professional perspectives on the matter.     

Cycle-ergometry stress testing and use of chronotropic reserve adjustment of ST depression for identification of significant coronary artery disease in clinical practice

Diagnostic reliability of indexations of peak exercise ST segment depression (DeltaST) for heart rate reserve (HRi) or chronotropic reserve (CR) to identify significant coronary artery disease (CAD) by cycle-ergometer exercise testing has not been evaluated previously. Exercise testing by upright cycle-ergometer (25 W/3 min) were performed in consecutive patients in primary prevention with history of exercise-related chest discomfort and cardiovascular risk factors, or with overt peripheral artery disease, with or type-2 diabetes associated with two or more additional cardiovascular risk factors. Coronary angiography was performed after the test to assess significant CAD. Three different criteria for definition of inducible myocardial ischemia were tested versus significant CAD: peak DeltaST>or=100 microV, ST/HRi>1.69 microV/bpm or ST/CR>1.76 microV/%. Diagnostic accuracy vs. CAD of DeltaST>or=100 microV, of ST/HRi>1.69 microV/bpm, and of ST/CR>1.76 microV/% were 78%, 72%, and 89% respectively; sensitivity and specificity of the three criteria were 91% and 50%, 84% and 43%, 88% and 93%, respectively. Abnormal ST/CR predicted CAD independent of risk factors, pre-test probability, and more strongly than DeltaST. Combination of ST/HRi and ST/CR criteria did not improve CAD prediction. In conclusions, in clinical setting in patients in primary prevention but with moderate-to-high pre-test probability of CAD, exercise testing by cycle-ergometry and use of ST/CR>1.76 microV/% showed elevated sensitivity and specificity, and the best accuracy for diagnosis of significant CAD.     

Absence of cytomegalovirus-resistance mutations after valganciclovir prophylaxis, in a prospective multicenter study of solid-organ transplant recipients

We investigated the emergence of cytomegalovirus (CMV) ganciclovir-resistance mutations in 301 high-risk solid-organ transplant (SOT) recipients after oral prophylaxis, for 100 days, with either valganciclovir or ganciclovir. For patients treated with ganciclovir, the incidence of CMV UL97 mutations was 1.9% (2/103) at the end of prophylaxis and 6.1% (2/33) for patients with suspected CMV disease up to 1 year after transplantation. No resistance mutations were detected in samples from valganciclovir-treated patients. Dual polymerase (UL54) and UL97 resistance mutations were not seen. Valganciclovir was associated with negligible risk of resistance and thus constitutes a useful alternative to ganciclovir prophylaxis for CMV in high-risk SOT recipients.     

Differences in presentation and follow-up between HIV-1 antibody positive teenagers and adults: the need for a more focused approach to care?

Our findings show a high rate of loss to follow-up in HIV-positive teenagers compared with adults. Of concern is the fact that this group also have high rates of sexually transmitted infections, unprotected sex and pregnancy. There is an urgent need to examine the reasons for this and adopt strategies to minimize risk-taking behaviour and to improve access to appropriate healthcare.

Childhood urinary tract infection in primary care: a prospective observational study of prevalence,diagnosis, treatment,and recovery

BackgroundThe prevalence of targeted and serendipitous treatment for, and associated recovery from, urinary tract infection (UTI) in pre-school children is unknown.AimTo determine the frequency and suspicion of UTI in children who are acutely ill, along with details of antibiotic prescribing, its appropriateness, and whether that appropriateness impacted on symptom improvement and recovery.MethodSystematic urine sampling from children aged <5years presenting in primary care with acute illness with culture in NHS laboratories.ResultsOf 6079 children’s urine samples, 339 (5.6%) met laboratory criteria for UTI and 162 (47.9%) were prescribed antibiotics at the initial consultation. In total, 576/7101 (8.1%) children were suspected of having a UTI prior to urine sampling, including 107 of the 338 with a UTI (clinician sensitivity 31.7%). Children with a laboratory-diagnosed UTI were more likely to be prescribed antibiotics when UTI was clinically suspected than when it was not (86.0% versus 30.3%, P<0.001). Of 231 children with unsuspected UTI, 70 (30.3%) received serendipitous antibiotics (that is, antibiotics prescribed for a different reason). Overall, 176 (52.1%) children with confirmed UTI did not receive any initial antibiotic. Organism sensitivity to the prescribed antibiotic was higher when UTI was suspected than when treated serendipitously (77.1% versus 26.0%; P<0.001). Children with UTI prescribed appropriate antibiotics at the initial consultation improved a little sooner than those with a UTI who were not prescribed appropriate antibiotics initially (3.5 days versus 4.0 days; P = 0.005).ConclusionOver half of children with UTI on culture were not prescribed antibiotics at first presentation. Serendipitous UTI treatment was relatively common, but often inappropriate to the organism’s sensitivity. Methods for improved targeting of antibiotic treatment in children who are acutely unwell are urgently needed.
