RESUMEN
INTRODUCTION: Approximately 20% of serious safety incidents involving palliative patients relate to medication. These are disproportionately reported when patients are in their usual residence when compared with hospital or hospice. While patient safety incident reporting systems can support professional learning, it is unclear whether these reports encompass patient and carer concerns with palliative medications or interpersonal safety. AIM: To explore and compare perceptions of (un)safe palliative medication management from patient, carer and professional perspectives in community, hospital and hospice settings. METHODS AND ANALYSIS: We will use an innovative mixed-methods study design combining systematic review searching techniques with cross-sectional quantitative descriptive analysis and interpretative qualitative metasynthesis to integrate three elements: (1) Scoping review: multiple database searches for empirical studies and first-hand experiences in English (no other restrictions) to establish how patients and informal carers conceptualise safety in palliative medication management. (2)Medication incidents from the England and Wales National Reporting and Learning System: identifying and characterising reports to understand professional perspectives on suboptimal palliative medication management. (3) Comparison of 1 and 2: contextualising with stakeholder perspectives. PATIENT AND PUBLIC INVOLVEMENT: Our team includes a funded patient and public involvement (PPI) collaborator, with experience of promoting patient-centred approaches in patient safety research. Funded discussion and dissemination events with PPI and healthcare (clinical and policy) professionals are planned. ETHICS AND DISSEMINATION: Prospective ethical approval granted: Cardiff University School of Medicine Research Ethics Committee (Ref 19/28). Our study will synthesise multivoiced constructions of patient safety in palliative care to identify implications for professional learning and actions that are relevant across health and social care. It will also identify changing or escalating patterns in palliative medication incidents due to the COVID-19 pandemic. Peer-reviewed publications, academic presentations, plain English summaries, press releases and social media will be used to disseminate to the public, researchers, clinicians and policy-makers.

PURPOSE: To examine whether the epidemiology of bacteraemia caused by methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin-resistant S. aureus (MRSA) differed in children aged <1 year and in comparison to older age groups. METHODOLOGY: English mandatory MRSA and MSSA surveillance data from 2006 and 2011, respectively, were collected. Epidemiological information was descriptively analysed in relation to methicillin susceptibility and patient age. Ninety-five percent confidence intervals (CIs) are reported.Results/Key findings. The average incidence rate of MSSA and MRSA bacteraemia in <1-year-olds was 60.2 and 4.8 episodes per 100â000 population per year, respectively. Of the cases of MSSA bacteraemia in children aged <1 year, 47.5â% (95â% CI: 45.1-50.0; n=760/1â599) were in neonates. With increasing age up to one year, more MSSA bacteraemias were detected ≥7 days after admission, ranging from 0â% (95â% CI: 0-2.5â%) in 0-2-day-olds to 68.4â% (95â% CI: 64.0-72.5â%; 333/487) in 8-28-day-olds and 50.5â% (95â% CI: 47.1-54.0â%; 423/837) in 29 day-1-year-olds, a higher proportion than in older children but similar to MRSA bacteraemia. Amongst <1-year-olds with MSSA bacteraemia, the underlying source was most commonly recorded as intravascular devices [34.4â% (95â%, CI: 30.5-38.6â%); n=190/552] whilst in older age groups this declined. A similar trend was observed for MRSA bacteraemia. CONCLUSIONS: Our analysis indicates that S. aureus bacteraemia in <1-year-olds is primarily healthcare-associated, unlike MSSA bacteraemia in older age groups. Paediatric-specific interventions targeted at the healthcare setting, such as neonatal unit-specific care bundles and paediatric device-specific strategies, are required.

Since 2001 it has been mandatory for acute hospital Trusts (groups of hospitals under the same management) in England to report all cases of bacteraemia due to Staphylococcus aureus together with information on their susceptibility or resistance to methicillin. This allowed the incidence of methicillin-resistant S. aureus (MRSA) bacteraemia (expressed as the number of cases per 1000 occupied bed days) to be determined for each Trust. In late 2005, the scheme was enhanced to collect demographic, clinical and epidemiological information on each case using a web-based data collection system. Analysis of this mandatory dataset has provided important information on the trends in MRSA bacteraemia in England and has documented a year-on-year decrease in incidence since 2006, following a government initiative in which Trusts were tasked with halving their MRSA bacteraemia rates over a 3 year period. In addition, the enhanced mandatory surveillance scheme has captured a wealth of data that have helped to further define the epidemiology of MRSA bacteraemia. It is to be hoped that based on the English experience of mandatory surveillance, other countries will consider the implementation of similar schemes, not only for MRSA but for other pathogens of public health importance.

OBJECTIVE: To investigate nevirapine concentrations in African HIV-infected children receiving divided Triomune tablets (stavudine+lamivudine+nevirapine). DESIGN: Cross-sectional study. METHODS: Steady-state plasma nevirapine concentrations were determined in Malawian and Zambian children aged 8 months to 18 years receiving Triomune in routine outpatient settings. Predictors from height-for-age, body mass index (BMI)-for-age, age, sex, post-dose sampling time and dose/m2/day were investigated using centre-stratified regression with backwards elimination (P<0.1). RESULTS: Of the 71 Malawian and 56 Zambian children (median age 8.4 vs 8.5 years, height-for-age -3.15 vs -1.84, respectively), only 1 (3%) of those prescribed > or =300 mg/m2/day nevirapine had subtherapeutic concentrations (<3 mg/l) compared with 22 (23%) of those prescribed <300 mg/m2/day; most children with subtherapeutic nevirapine concentrations were taking half or quarter Triomune tablets. Lower nevirapine concentrations were independently associated with lower height-for-age (indicating stunting) (0.37 mg/l per unit higher [95% confidence interval (CI): -0.003, +0.74]; P=0.05), lower prescribed dose/m2 (+0.89 mg/l per 50 mg/m2 higher [95% CI: 0.32, 1.46]; P=0.002) and higher BMI-for-age (indicating lack of wasting) (-0.42 mg/l per unit higher [95% CI: -0.80, -0.04]; P=0.03). CONCLUSIONS: Currently available adult fixed-dose combination tablets are not well suited to children, particularly at younger ages: Triomune 30 is preferable to Triomune 40 because of the higher dose of nevirapine relative to stavudine. Further research is required to confirm that concentrations are reduced in stunted children but increased in wasted children. Development of appropriate paediatric fixed-dose combination tablets is essential if antiretroviral therapy is to be made widely available to children in resource-limited settings.

The degree of population replacement in the British Isles associated with cultural changes has been extensively debated. Recent work has demonstrated that comparisons of genetic variation in the British Isles and on the European Continent can illuminate specific demographic processes in the history of the British Isles. For example, Wilson et al. used the similarity of Basque and Celtic Y chromosomes to argue for genetic continuity from the Upper Palaeolithic to the present in the paternal history of these populations (see also ). Differences in the Y chromosome composition of these groups also suggested genetic signatures of Norwegian influence in the Orkney Islands north of the Scottish mainland, an important center of Viking activities between 800 and 1300 A.D. More recently, Weale et al. argued for substantial Anglo-Saxon male migration into central England based on the analysis of eight British sample sets collected on an east-west transect across England and Wales. To provide a more complete assessment of the paternal genetic history of the British Isles, we have compared the Y chromosome composition of multiple geographically distant British sample sets with collections from Norway (two sites), Denmark, and Germany and with collections from central Ireland, representing, respectively, the putative invading and the indigenous populations. By analyzing 1772 Y chromosomes from 25 predominantly small urban locations, we found that different parts of the British Isles have sharply different paternal histories; the degree of population replacement and genetic continuity shows systematic variation across the sampled areas.
