    For considering vaccine-prevention of pneumococcal acute otitis media (PncAOM), relationships between pneumococcal carriage, respiratory infection and PncAOM need to be understood. We analyzed nasopharyngeal samples collected from 329 unvaccinated Finnish children aged 2-24 months at scheduled visits and at visits during respiratory infection in 1994-97. We assessed temporal associations of respiratory infection with pneumococcal acquisition and whether PncAOM hazard depends on the relative timing of acquisition and the infection onset. The data comprised 607 person-years of risk-time for acquisition, 245 person-months of concurrent respiratory infection and carriage, and 119 episodes of PncAOM. The acquisition hazard was 3-fold in the month preceding respiratory sickness (hazard ratio, HR 3.5, 90% credible interval CI 2.9, 4.1) as compared to acquisition in healthy children. Moreover, the PncAOM hazard was markedly higher (HR 3.7, 90% CI 2.4, 5.3) during the first month of carriage acquired around the acute phase of respiratory infection (between 1 month before and 1 week after the sickness onset), as compared to carriage acquired later during sickness. The high proportion (76%) of PncAOM events occurring within 1 month of acquisition was due to frequent acquisition being associated with respiratory infection as well as the susceptibility of such acquisition to cause otitis media

    Segregation, precipitation, and \alpha-\alpha' phase separation in Fe-Cr alloys: a multi-scale modelling approach

    Segregation, precipitation, and phase separation in Fe-Cr systems is investigated. Monte Carlo simulations using semiempirical interatomic potential, first-principles total energy calculations, and experimental spectroscopy are used. In order to obtain a general picture of the relation of the atomic interactions and properties of Fe-Cr alloys in bulk, surface, and interface regions several complementary methods has to be used. Using Exact Muffin-Tin Orbitals method the effective chemical potential as a function of Cr content (0-15 at.% Cr) is calculated for a surface, second atomic layer and bulk. At ~10 at.% Cr in the alloy the reversal of the driving force of a Cr atom to occupy either bulk or surface sites is obtained. The Cr containing surfaces are expected when the Cr content exceeds ~10 at.%. The second atomic layer forms about 0.3 eV barrier for the migration of Cr atoms between bulk and surface atomic layer. To get information on Fe-Cr in larger scales we use semiempirical methods. Using combined Monte Carlo molecular dynamics simulations, based on semiempirical potential, the precipitation of Cr into isolated pockets in bulk Fe-Cr and the upper limit of the solubility of Cr into Fe layers in Fe/Cr layer system is studied. The theoretical predictions are tested using spectroscopic measurements. Hard X-ray photoelectron spectroscopy and Auger electron spectroscopy investigations were carried out to explore Cr segregation and precipitation in Fe/Cr double layer and Fe_0.95Cr_0.05 and Fe_0.85Cr_0.15 alloys. Initial oxidation of Fe-Cr was investigated experimentally at 10^-8 Torr pressure of the spectrometers showing intense Cr_2O_3 signal. Cr segregation and the formation of Cr rich precipitates were traced by analysing the experimental spectral intensities with respect to annealing time, Cr content, and kinetic energy of the exited electron.Comment: 16 pages, 14 figures, 52 reference

    Empowering patient education on self-care activity among patients with colorectal cancer - a research protocol for a randomised trial

    Get PDF
    Background: Chemotherapy-induced side effects may have a negative effect on nutrition intake, thus increasing the risk of malnutrition and consequently, other serious complications for patients with cancer. The prevalence of malnutrition is common among patients with colorectal cancer. Nurse-led empowering education may have a positive effect on self-care activity in this patient group. Therefore, our purpose is to develop an empowering educational nursing intervention and test its effect on self-care activation and knowledge level among patients with colorectal cancer during chemotherapy. Secondary outcomes are quality of life and risk of malnutrition. Methods: An interdisciplinary expert group developed a face-to-face empowering educational intervention using teach-back method. A two-arm, single-centre, superiority trial with stratified randomisation (1:1) and pre-post measures will be used to assess the effect of the intervention compared to standard care. Patients (N = 40 + 40) will be recruited in one university hospital outpatient clinic in Finland. Eligibility criteria are adult patients diagnosed with colorectal cancer starting oral fluoropyrimidine or combination chemotherapy treatment. A registered nurse experienced in oncology will deliver the intervention 2 weeks after the first chemotherapy. Outcomes are measured before intervention (M0) and after a two-month follow-up period (M1). Discussion: This study will assess whether nurse-led empowering education using teach-back method is effective on self-care activity among patients with colorectal cancer. If the intervention has a positive effect, it may be implemented into patient education in a corresponding context.Peer reviewe

    Consistent practice for pressure ulcer prevention in long-term older people care: A quasi-experimental intervention study

    Get PDF
    Background Consistent practice, an agreed clinical practice based on evidence, has been considered as a base for effective provision of quality and safety of care. As a result, patients have an equal quality of care regardless of the organisation or worker. However, despite the international guidelines, pressure ulcer prevention practices vary in long-term older people care.Aim To develop, implement and evaluate the impact of renewed, consistent practice for pressure ulcer prevention, in long-term older people care.Design A quasi-experimental intervention study.Methods Two long-term older people care facilities chosen with convenience sampling were randomly allocated to intervention or comparison group. Registered and practical nurses, in total 141/112, participated in the study. The renewed consistent practice based on international guidelines for pressure ulcer prevention was developed and implemented using the Operational Model for Evidence-Based Practices (OMEBP). Frequencies and agreement of PU prevention practices in line with international guidelines in the care facilities were measured using the PUPreP instrument.Results In the intervention facility, improvement in line with international guidelines was seen in the frequency of PU prevention practices in risk assessment, nutrition, pressure-relieving devices and documentation. Furthermore, improvement was seen in the intervention facility in all six areas of agreement on practices.Conclusions The results of this study support the implementation of PU prevention guidelines in long-term older people care (LOPC) and more widely in healthcare settings for older people to promote consistent practice, and safety and equal quality of care

    Critical care nurses' self-assessed patient observation skills: a cross-sectional survey study

    Get PDF
    BACKGROUND: Observing a patient's clinical condition is an important responsibility of critical care nurses and an essential component of their competence. Critical care nurses' patient observation skills contribute to patient safety and quality of care. These observation skills have not been assessed or measured previously.AIM: The aim of this study was to measure the self-assessed level of critical care nurses' patient observation skills and to explore the factors associated with these skills.STUDY DESIGN: This was a multicentre cross-sectional survey conducted in Finland.METHODS: The sample consisted of critical care nurses working at Finnish university hospitals. The data were collected between September 2017 and January 2018 using an instrument developed for the study - Patient Observation Skills in Critical Care Nursing (visual analogue scale 0-100). Descriptive and inferential statistics were used to analyse the data.RESULTS: A total of 372 critical care nurses (49%) responded. Finnish critical care nurses assessed their patient observation skills overall as excellent. The bio-physiological foundation was assessed as good, whereas skills in using observation methods and skills in recognizing changing clinical condition were assessed as excellent. Education for special tasks in intensive care units, information searching in scientific journals, working experience in critical care nursing and critical care nurses' perception of critical care as a preferred field of nursing were factors promoting patient observation skills.CONCLUSIONS AND RELEVANCE TO CLINICAL PRACTICE: The study provided a novel instrument for measuring critical care nurses' patient observation skills. The instrument may be used as an assessment tool in clinical practice and education. Developing orientation and on-the-job training in intensive care units are essential in assuring critical care nurses' adequate patient observation skills. Patient observation skills could be developed during nursing education by providing students with opportunities for clinical training and applying patient cases in virtual learning environments.</p

    Neglecting the care of older people in residential care settings: A national document analysis of complaints reported to the Finnish supervisory authority

    Get PDF
    Neglecting to provide older people with the care they need in residential care settings leads to human suffering and increased service needs. Research is lacking on neglect in older people's residential care and one way to assess the key issues is to study complaints. The aim of this study was to analyse official complaints related to allegations of neglect in residential care settings caring for older people in Finland. The data covered 317 complaints that were recorded in the national database in 2018 and 2019. The analysis of the complaints yielded 2,922 observations of neglect in older people's care in residential care settings. Based on our results, most of the complaints were made by family members when the patients were alive and their motivation was to improve the care their relative received, as well as the care of others, in the residential care home. The complaints focused on neglecting clinical care, including restricting older people's movements, not providing daily activities and not paying sufficient attention to their hygiene and secretions. Other complaints included issues relating to nutrition, medication, communication and issues that compromised their privacy, respect and dignity. Nearly three of four complaints identified staffing issues in relation to neglect and most of the complaints concerned private, rather than public, residential care homes. Although the complaints only concerned a small proportion of the annual care provided, more attention should be paid to care practices that prevent neglect in residential care and to multi-level monitoring for dignified care

    Salivary antibodies induced by the seven-valent PncOMPC conjugate vaccine in the Finnish Otitis Media Vaccine Trial

    BACKGROUND: Mucosal antibodies have been suggested to have a role in defence against pneumococcal infections. We investigated here the ability of a seven-valent pneumococcal conjugate vaccine, PncOMPC, to induce mucosal immune response. METHODS: Healthy Finnish children (n = 111), a subcohort of the Finnish Otitis Media Vaccine Trial, were recruited and 56 of them were immunised with the PncOMPC at the age of 2, 4, and 6 months. At 12 months of age, 49 of them received the PncOMPC and 7 were vaccinated with the pneumococcal polysaccharide vaccine (PncPS) as a booster. The control group of 55 children received a hepatitis B vaccine at the same ages. Salivary anti-Pnc IgG, IgA, IgA1, and IgA2 antibodies to serotypes 6B, 14, 19F, and 23F were measured in both groups at the age of 7 and 13 months. RESULTS: Salivary anti-Pnc IgG and IgA were detected more often in the PncOMPC than in the control group. However, the difference between groups was significant only for 19F and 23F IgA concentrations at the age of 7 months. At the age of 13 months, antibody concentrations did not differ between PncOMPC and control groups. The rises in IgA concentrations between 7 and 13 months of age were mainly of subclass IgA1. Further, there is a clear trend that PncPS booster induces higher salivary anti-Pnc PS antibody concentrations than the PncOMPC. CONCLUSION: We found that PncOMPC can induce a mucosal IgA response. However, the actual impact of mucosal antibodies in protection against pneumococcal infections is not clear

    S. pneumoniae transmission according to inclusion in conjugate vaccines: Bayesian analysis of a longitudinal follow-up in schools

    Get PDF
    BACKGROUND: Recent trends of pneumococcal colonization in the United States, following the introduction of conjugate vaccination, indicate that non-vaccine serotypes tend to replace vaccine serotypes. The eventual extent of this replacement is however unknown and depends on serotype-specific carriage and transmission characteristics. METHODS: Here, some of these characteristics were estimated for vaccine and non-vaccine serotypes from the follow-up of 4,488 schoolchildren in France in 2000. A Bayesian approach using Markov chain Monte Carlo data augmentation techniques was used for estimation. RESULTS: Vaccine and non-vaccine serotypes were found to have similar characteristics: the mean duration of carriage was 23 days (95% credible interval (CI): 21, 25 days) for vaccine serotypes and 22 days (95% CI: 20, 24 days) for non-vaccine serotypes; within a school of size 100, the Secondary Attack Rate was 1.1% (95% CI: 1.0%, 1.2%) for both vaccine and non-vaccine serotypes. CONCLUSION: This study supports that, in 3–6 years old children, no competitive advantage exists for vaccine serotypes compared to non-vaccine serotypes. This is an argument in favour of important serotype replacement. It would be important to validate the result for infants, who are known to be the main reservoir in maintaining transmission. Overall reduction in pathogenicity should also be taken into account in forecasting the future burden of pneumococcal colonization in vaccinated populations
