    Streptococcus pneumoniae of serotype 3 possess a mucoid capsule and cause disease associated with high mortality rates relative to other pneumococci. Phylogenetic analysis of a complete reference genome and 81 draft sequences from clonal complex 180, the predominant serotype 3 clone in much of the world, found most sampled isolates belonged to a clade affected by few diversifying recombinations. However, other isolates indicate significant genetic variation has accumulated over the clonal complex’s entire history. Two closely related genomes, one from the blood and another from the cerebrospinal fluid, were obtained from a patient with meningitis. The pair differed in their behaviour in a mouse model of disease and in their susceptibility to antimicrobials, with at least some of these changes attributable to a mutation that upregulated the patAB efflux pump. This indicates clinically important phenotypic variation can accumulate rapidly through small alterations to the genotype

    Psychometric evaluation of a short-form version of the Swedish “Attitudes to and Knowledge of Oral Health” questionnaire

    Background Healthcare professionals’ attitudes to and knowledge of oral health are fundamental to providing good oral health care to older adults. One instrument that assesses healthcare professionals’ attitudes to and knowledge of oral health in a Swedish context is the “Attitudes to and Knowledge of Oral health” (AKO) questionnaire. Two of the three item-groups of the AKO have previously been validated in a Swedish context. However, it is crucial that all three item-groups are validated, and beneficial to design a shorter, easy-to-use questionnaire for healthcare professionals while maintaining adequate integrity of its reliability and validity. Therefore, the present study aims to develop a short-form version of AKO and to secure its psychometric properties. Methods Psychometric evaluation with Classical Test Theory and Item Response Theory to validate and shorten AKO with 611 healthcare professionals from a population of 1159 working in a municipality in an urban area in western Sweden. Results Of the original 16 items in the AKO, 13 were shown to warrant retention in the abbreviated/shortened form. These showed acceptable validity and reliability for assessing healthcare professionals’ attitudes to and knowledge of oral health. Conclusion This validated short-form version of AKO shows acceptable validity and reliability after being reduced to 13 items, structured in a 3-part scale. The items are consistent with the total scale, indicating that the internal consistency is acceptable. Future studies should be performed to evaluate AKO in other groups of healthcare professionals, across cultures, languages, and so on, to investigate its use and strengthen its validity and reliability.CC BY 4.0© The Author(s) 2022.

    Home care assistants' attitudes and perceptions of caring for people at the end of life in their homes in Sweden

    The ageing population is increasing worldwide, with older people often having multimorbidity and a need for help with activities and personal care. Home Care Assistants (HCAs) are central to the provision of care in the home. They meet older people approaching the end of life and their relatives. Little is known about HCAs attitudes towards caring for a dying person and how aspects such as education, age, earlier care experiences, care education and experience of caring for dying older people affect their attitudes. The aim was to describe HCAs' attitudes towards the care of dying persons living in their ordinary homes. This cross-sectional study used the Frommelt Attitude Toward Care of the Dying Scale (FATCOD) for data collection during December 2017 and January 2018, and descriptive statistics and regression analysis for data analysis. The participants were HCAs (n = 127, 96% of those eligible) in a municipality in central Sweden. An overall positive attitude was reported. About 32% lacked formal HCA education although 93% had experience of interacting with a dying person. Age, HCA education, internal palliative care education, number of years' experience and previous experience of caring for a dying person were independently associated with HCAs' attitudes. In the multivariate regression analysis, age and years of experience were the only significant predictors of HCAs' attitudes towards caring for dying care recipients. Young employees without HCA education and experience of a dying person might be vulnerable in situations involving caring for a dying person. Communicating about death and dying, forming a relationship with the care recipient and the family, and providing care when a person is dying can be challenging. Implications: Young employees without HCA education and experience of interacting with a dying person needs to be prepared for the situation. This needs to be considered by stakeholders and social and healthcare organisations

    Development and Psychometric Evaluation of a New Short Version of the Swedish Frommelt Attitudes Toward Care of the Dying Scale

    BACKGROUND: The Frommelt Attitudes Toward Care of the Dying (FATCOD) is widely used as a measure of attitudes toward care of dying patients. However, poor factor structure and item redundancy have been reported across the literature. OBJECTIVE: A short version of the questionnaire is needed, to facilitate effective assessments of the attitudes of those caring for dying patients. The purpose of this study was to develop a FATCOD-Short Form and to secure its psychometric properties. INTERVENTIONS/METHODS: Data gathered from 1000 nurses in previous studies were pooled and reanalyzed. Principal components analysis and confirmatory factor analysis were utilized to assess the factor structure of the FATCOD-30. A Rasch model was used to evaluate the measurement functioning of the scale. RESULTS: Of the original 30 items, 9 items of FATCOD were chosen for retention in the short form based on the principal components analysis, floor or ceiling effects, interitem correlations, and item-total correlation. All 9 items had good internal reliability. Both confirmatory factor analysis and Rasch analysis supported the unidimensionality of the FATCOD-Short Form. CONCLUSIONS: The 9-item FATCOD-Short Form demonstrates evidence of acceptable validity and reliability to identify nurses' attitudes toward caring for dying persons because of its brevity and comprehensive content. IMPLICATIONS FOR PRACTICE: When changing curricula in nursing education or implementing new procedures in nursing practice, it is important to have valid instruments to evaluate the results of the change. Such instruments should not be too lengthy or complicated. FATCOD-Short Form is a brief and valid instrument that can be easily used
