- Antibiotic resistance in pneumococci is due to the spread of strains belonging to a limited number of clones. The Spain(9v)-3 clone of sequence type (ST)156 is one of the most successful clones with reduced susceptibility to penicillin [pneumococci nonsusceptible to penicillin (PNSP)]. In Sweden during 2000-2003, a dramatic increase in the number of PNSP isolates was observed. Molecular characterization of these isolates showed that a single clone of sequence type ST156 increased from 40% to 80% of all serotype 14, thus causing the serotype expansion. Additionally, during the same time period, we examined the clonal composition of two serotypes 9V and 19F: all 9V and 20% of 19F isolates belonged to the clonal cluster of ST156, and overall approximate to 50% of all PNSP belonged to the ST156 clonal cluster. Moreover, microarray and PCR analysis showed that all ST156 isolates, irrespective of capsular type, carried the rlrA pilus islet. This islet was also found to be present in the penicillin-sensitive ST162 clone, which is believed to be the drug-susceptible ancestor of ST156. Competitive experiments between related ST156 serotype 19F strains confirmed that those containing the rlrA pilus islet were more successful in an animal model of carriage. We conclude that the pilus island is an important biological factor common to ST156 isolates and other successful PNSP clones. In Sweden, a country where the low antibiotic usage does not explain the spread of resistant strains, at least 70% of all PNSP isolates collected during year 2003 carried the pilus islet.

- Background: The aim of this study was to explore the use of complementary and alternative medicine (CAM) in cancer patients across a number of European countries.Methods: A descriptive survey design was developed. Fourteen countries participated in the study and data was collected through a descriptive questionnaire from 956 patients.Results: Data suggest that CAM is popular among cancer patients with 35.9% using some form of CAM (range among countries 14.8% to 73.1%). A heterogeneous group of 58 therapies were identified as being used. Herbal medicines and remedies were the most commonly used CAM therapies, together with homeopathy, vitamins/minerals, medicinal teas, spiritual therapies and relaxation techniques. Herbal medicine use tripled from use before diagnosis to use since diagnosis with cancer. Multivariate analysis suggested that the profile of the CAM user was that of younger people, female and with higher educational level. The source of information was mainly from friends/family and the media, while physicians and nurses played a small part in providing CAM-related information. The majority used CAM to increase the body's ability to fight cancer or improve physical and emotional well-being, and many seemed to have benefited from using CAM (even though the benefits were not necessarily related to the initial reason for using CAM). Some 4.4% of patients, however, reported side-effects, mostly transient.Conclusions: It is imperative that health professionals explore the use of CAM with their cancer patients, educate them about potentially beneficial therapies in light of the limited available evidence of effectiveness, and work towards an integrated model of health-care provision.

- The effects of pneumococcal conjugated vaccines (PCVs) need to be investigated. In Stockholm County, Sweden, PCV7 was introduced in the childhood immunisation programme in 2007 and changed to PCV13 in 2010.Over 90% of all invasive isolates during 2005–2014 (n=2336) and carriage isolates, 260 before and 647 after vaccine introduction, were characterised by serotyping, molecular typing and antibiotic susceptibility, and serotype diversity was calculated. Clinical information was collected for children and adults with invasive pneumococcal disease (IPD).The IPD incidence decreased post-PCV7, but not post-PCV13, in vaccinated children. Beneficial herd effects were seen in older children and adults, but not in the elderly. The herd protection was more pronounced post-PCV7 than post-PCV13. PCV7 serotypes decreased. IPD caused by PCV13 serotypes 3 and 19A increased post-PCV7. Post-PCV13, serotypes 6A and 19A, but not serotype 3, decreased. The serotype distribution changed in carriage and IPD to nonvaccine types, also in nonvaccinated populations. Expansion of non-PCV13 serotypes was largest following PCV13 introduction. Serotype diversity increased and nonvaccine clones emerged, such as CC433 (serotype 22F) in IPD and CC62 (serotype 11A) in carriage. In young children, meningitis, septicaemia and severe rhinosinusitis, but not bacteraemic pneumonia, decreased.Pneumococcal vaccination leads to expansion of new or minor serotypes/clones, also in nonvaccinated populations.

- BACKGROUND: This study aims to examine the effectiveness of a self-management multimodal comprehensive coping strategy program (CCSP) on quality of life (QOL) among breast cancer patients 1 year after treatment.METHODS: Patients (n = 110) with stage II, III, or IV breast cancer scheduled to receive high dose chemotherapy and autologous hematopoietic stem cell transplantation were randomized to either CCSP treatment or control group. The CCSP intervention was taught 2 week before hospital admission with reinforcement at specified times during treatment and 3 months after discharge. The CCSP components included educational information, cognitive restructuring, coping skills enhancement, and relaxation with guided imagery. Instruments administered at baseline included the following: Quality of Life Index-Cancer Version (QOLI-CV), State-Trait Anxiety Inventory, Beck Depression Inventory, and Coping Strategies Questionnaire. At 1-year follow-up, patients (n = 73) completed and returned the follow-up QOLI-CV.RESULTS: Patients were mainly ≥40 years of age, married, Caucasian, and diagnosed with advanced breast cancer. A model measuring effectiveness of CCSP on QOL (total and subscale) at 1-year follow-up showed that the CCSP group (n = 38) had significant improvement in overall QOL (p < 0.01), health and functioning (p < 0.05), and socioeconomic (p < 0.05) and psychological/spiritual well-being (p < 0.01) compared with the control group (n = 35). The CCSP patients frequently used the CCSP to manage psychological (51%) and sleep problems (60%).CONCLUSIONS: The CCSP improved QOL for patients at 1-year follow-up. Patients overwhelmingly reported that CCSP was beneficial. The CCSP as an effective coping intervention has potential as a self-management program for breast cancer survivors.

- Objective: To test the hypothesis that Antonovsky's concept of sense of coherence (SOC) predicts stressful events, coping strategies, health status, and quality of life (QoL) in a cohort of postmenopausal women (n = 131) with newly diagnosed primary or recurrent breast cancer.Methods: Regression analyses of longitudinal data at baseline through 6 months following breast cancer diagnosis examined the relationships between SOC (13-item version), daily assessment of coping with stressful events, health status, and QoL (EORTC QLQ-30).Results: The findings support Antonovsky's concept of SOC. Women with strong SOC reported fewer stressful events and more days without stressful events. They used more coping strategies and more frequently used distraction, situation redefinition, direct action, and relaxation, but seldom religion, to cope with stressful events, and reported better health status and QoL. Women with weak SOC experienced more distress and used fewer coping strategies, and they more frequently used coping strategies such as catharsis and seeking social and spiritual support, but seldom acceptance of the situation. They reported worse health status and QoL, regardless of disease stage or treatment. The relationships between SOC and health status and QoL were linear.Conclusions: Sense of coherence significantly predicts distress, number and type of coping strategies such as direct action and relaxation, health status, and QoL in women with breast cancer. Our data suggest that the SOC scale may be a useful screening tool to identify individuals particularly vulnerable to distress and unable to cope adequately. Assessing SOC strength may assist health care providers to provide individualized patient interventions.
