    Little is known about the clinical relevance of nontuberculous mycobacteria (NTM) in the Arabian Peninsula. We assessed the prevalence and studied a random sample of isolates at a reference laboratory in Muscat, Oman. NTM cause disease in this region, and their prevalence has increased

    The CA 125 II assay on the Elecsys(R) 2010 analyzer was evaluated in an international multicenter trial. Imprecision studies yielded within-run CVs of 0.8-3.3% and between-day CVs of 2.4-10.9%; CVs for total imprecision in the manufacturer's laboratory were 2.4-7.8%. The linear range of the assay extended to at least 4500 kilounits/L (three decades). Interference from triglycerides (10.3 mmol/L), bilirubin (850 micromol/L), hemoglobin (1.1 mmol/L), anticoagulants (plasma), and several widely used drugs was undetectable. Method comparisons with five other CA 125 II assays showed good correlation but differences in standardization. A 95th percentile cutoff value of 35 kilounits/L was calculated from values measured in 593 apparently healthy (pre- and postmenopausal) women. In 95% of patients with benign gynecological diseases CA 125 was </=190 kilounits/L; 63% of patients with newly diagnosed ovarian carcinoma had values >190 kilounits/L. A comparison of CA 125 values obtained with the Elecsys test and with other common CA 125 tests in monitored patients being treated for ovarian cancer showed identical patterns. In conclusion, the Elecsys CA 125 II assay is linear over a broad range, yields precise and accurate results, is free from interferences, and compares well with other assays

    ICT as an instrument for social and emotional ageing. A qualitative study with older adults with cognitive impairments

    Inspired by theories from the field of social and emotional aging, we studied the use of ICTs by older adults with cognitive impairments. By means of qualitative interviews (N=30) with older adults with cognitive impairments and their relatives, we got a detailed picture of the role of ICTs in their daily lives. First, our data showed that older adults with cognitive impairments used ICTs to enhance their social and emotional wellbeing. This involved social interaction, feelings of belongingness, and engagement in hobbies and regular daily activities. Second, our research provided insight into the strategies applied when ICT use became too difficult, with a considerable role for the social network. When the network offered help upon request or proactively encouraged the older person, this increased the perception of control. This also applied to the indirect use of ICTs, when someone from the social network operated the devices. Denying the older person the use of ICTs undermined the perception of control. The findings provide insight into how the potential of ICT can be exploited for this target group. We end the paper with practical recommendations

    A taxonomy to assess the interaction between nurses and children:Development and reliability

    Aims and objectives The aim of this study was to develop a valid and reliable instrument to assess the nurse-child interaction during medical or nursing interventions. Background Communication is an important competency for the professional practice of nurses and physicians. The nurse-patient relationship is fundamental for high-quality care. It has been suggested that if nurses have more skills to interact with children, care will be less distressing and less painful for the children. Design A qualitative observational psychometric study; the GRRAS checklist was used. Methods In-depth video-analyses, taxonomy development (19 videos) and testing it is psychometric properties (10 videos). Three observers micro-analysed video recordings of experienced nurses changing children's wound dressing in a specialised Burn Centre. Results The nurse-child interaction taxonomy (NCIT) was developed to observe and score the interactional behaviour between nurse and child. The taxonomy has three main patterns: being considerate, attuning oneself, and procedural interventions, subdivided in eight dimensions. These dimensions contain 16 elements that can be observed and scored on a 7-point scale. Intra-rater, inter-rater reliability and agreement were good. Conclusions This study shows that interaction between nurses and children can be assessed reliably with the NCIT by an experienced observer or alternatively, scoring by two observers is recommended. Relevance to clinical practice The development of the taxonomy is an important step to find evidence for the best way for nurses to interact with children during nursing interventions or medical events and as such, ultimately, contributes to providing the best care possible
