Potentially inappropriate prescribing among people with dementia in primary care: a retrospective cross-sectional study using the Enhanced Prescribing Database

Background: Little is known about prescribing appropriateness for community-dwelling people with dementia (PWD).
Objective To estimate potentially inappropriate prescribing (PIP) prevalence among PWD in primary care in Northern Ireland, and to investigate associations between PIP and polypharmacy, age and gender.

Methods: A retrospective cross-sectional study was conducted, using data from the Enhanced Prescribing Database. Patients were eligible if a medicine indicated for dementia management was dispensed to them during 01/01/2013 – 31/12/2013. Polypharmacy was indicated by use of ≥4 repeat medications from different drug groups. A subset of the Screening Tool of Older Persons Potentially Inappropriate Prescriptions (STOPP) criteria, comprising 36 indicators, was applied to the dataset. Overall prevalence of PIP and the prevalence per each STOPP criterion was calculated as a proportion of all eligible persons in the dataset. Logistic regression was used to investigate associations between PIP, polypharmacy, age and gender.

Results: The study population comprised 6826 patients. Polypharmacy was observed in 81.5% (n=5564) of patients. PIP prevalence during the study period was 64.4% (95% CI 63.2 – 65.5; n=4393). The most common instance of PIP was the use of anticholinergic/antimuscarinic medications (n=1718; 25.2%; 95% CI 24.2 – 26.2). In multivariable analyses, both polypharmacy and gender (being female) were associated with PIP, with odds ratios of 7.6 (95% CI 6.6 – 8.7) and 1.3 (95% CI 1.2 – 1.4) respectively. No association was observed between PIP and age, after adjustments for gender and polypharmacy.

Conclusion: This study identified a high prevalence of PIP in community-dwelling PWD. Future interventions may need to focus on certain therapeutic categories and polypharmacy.

Integrated approach to teaching English in primary and preschool

O presente trabalho de investigação apresenta um estudo que procurou observar comportamentos de literacia emergente numa língua estrangeira (Inglês) em contexto da educação pré-escolar. Procedeu-se à conceção e implementação de uma abordagem integrada ao ensino da língua inglesa, através numa abordagem metodológica inspirada no paradigma investigação-ação, percecionada como oportunidade de inovação pedagógica e de formação de professores. O estudo foi desenvolvido em simultâneo no 1ºCEB, tendo como principal objetivo comparar os comportamentos e atitudes dos alunos de outra faixa etária relativamente aos comportamentos de literacia em língua estrangeira. Os dados foram recolhidos através da observação, gravação de aulas, posteriormente transcritas, diários do investigador, questionários, portfolios dos alunos e entrevistas semi-estruturadas a especialistas na área da pedagogia de línguas estrangeiras, analisados através da aplicação de técnicas de análise de conteúdo como procedimento de análise do corpus. Os resultados demonstram a relevância de abordagens integradas de cariz lúdico na promoção de comportamentos de leitura e escrita emergente, estimulando assim motivação intrínseca nas crianças pela aprendizagem da língua e cultura-alvo. Por conseguinte, os comportamentos observados de literacia emergente em língua estrangeira permitem estabelecer uma analogia com as crianças bilingues, na medida em que ao aprenderem uma outra língua desenvolvem em sincronia a sua flexibilidade mental e estratégias de auto-regulação em diversas áreas de conhecimento. Os resultados permitem ainda concluir que estratégias promotoras de motivação intrínseca como o lúdico e o storytelling são vitais na sensibilização à diversidade linguística e cultural, por oposição aos resultados evidenciados pela estratégia nacional para o ensino de línguas estrangeiras no 1.ºCEB. As principais implicações deste estudo sugerem a possibilidade de generalização da língua estrangeira na educação pré-escolar, sendo esta etapa compreendida como um período privilegiado na prevenção de insucesso na leitura e escrita na aprendizagem de uma língua estrangeira. Deste modo, a educação pré-escolar pode ser considerada como um tempo fundador do futuro linguístico das crianças, numa perspetiva de educação linguística ao longo da vida.

Public-private partnerships and efficiency in public procurement of primary healthcare infrastructure: a qualitative research in the NHS UK

Aim There is growing interest in the contribution of public-private partnerships (PPPs) bridging the shortage of financial resources and management expertise in developing public healthcare infrastructure. However, few studies have evidenced PPPs’ ability in increasing efficiency in public procurement of primary healthcare infrastructure. The aim of this study was to assess to what extent PPPs would increase efficiency in public procurement of primary healthcare facilities. Subject and Methods A qualitative analysis, adopting a realistic research evaluation method, used data collected from a purposive sample of public (n=23) and private sector staff (n=2) directly involved in the UK National Health Service Local Improvement Finance Trust (LIFT). Results We find a positive association of LIFT helping to bridge public sector capital shortages for developing primary care surgeries. LIFT is negatively associated with inefficient procurement because it borrows finance from private banks, leaving public agencies paying high interest rates. The study shows that some contextual factors and mechanisms in LIFT play a major part in obstructing public staff from increasing procurement efficiency. Conclusion PPP’s ability to increase efficiency may be determined by contextual factors and mechanisms that restrict discretion over critical decisions by frontline public sector staff. Developing their capacity in monitoring PPP activities may make partnerships more efficient.

Modelling antropogenic impact on primary production of sado estuary

The assessment of human impact on complex estuarine systems is a multidisciplinary task that is highly demanding in terms of measurements and fieldwork. Nowadays the use of inexpensive and reliably modeling tools can substantially reduce the amount of measurements needed to characterize a system. These tools are also a convenient way to forecast the future evolution of the system and to study the impact of different scenarios of human influence. In this communication a modeling system composed by hydrodynamic, transport and ecological models is used to assess the current trophic state of Sado Estuary (Portugal) and to predict the future trends of the system based on different scenarios of human intervention. Special care is taken to the impact of changing riverine nutrient loads. Sado estuary is a large European estuary that has been considered until now in good trophic conditions with eutrophication appearing only in some isolated spots. Nevertheless in recent years some studies point out that the situation is changing. Sado estuary is a system with strong environmental opposing interests. It hosts a major industrial and urban center around the city of Setúbal and the upper reaches are used to intensive cultures such as rice. On the other hand the estuary possess an important ecological value since it is used by several important species of fish as a spawning and nursery area and it’s wetlands are used by many species of birds as winter shelters. Due to it’s importance the majority of Sado Estuary is considered as Natural Reserve.

Correlates of facial expressions in the primary visual cortex

Face detection and recognition should be complemented by recognition of facial expression, for example for social robots which must react to human emotions. Our framework is based on two multi-scale representations in cortical area V1: keypoints at eyes, nose and mouth are grouped for face detection [1]; lines and edges provide information for face recognition [2].

Pharmacotherapy follow-up of patients with diabetes mellitus in a Primary Health Care Unit

Background: Diabetes mellitus is one of the major causes of chronic morbidity and loss of quality of life, and it seems to be increasing in the coming decades. Overall prevalence of diabetes in Portugal in 2010, according to the latest National Observatory of Diabetes Report, was 12.4%, which corresponds to a total of approximately 991 thousand individuals aged between 20 and 79 years. The level of control of diabetes mellitus, as measured by glycosilated haemoglobin A1c(HbA1c) influences the long-term risk of macrovascular and microvascular complications. Given the frequent association of diabetes with hypertension/dyslipidemia/overweight, managing these risk factors is a crucial part of the diabetes control.

Interpersonal Relationships in the Primary Classroom: an Analysis of Social and Affective Outcomes

Recent research regarding the quality of relationships in primary classrooms has focused largely on the enhancement and development of cognitive skills. The study reported here focused on a range of social and affective outcomes with the intention of broadening our understanding of the classroom as an interactive system, from the child's perspective. This paper provides empirical evidence on children's perceptions at Key Stage 2 (pupil age 7-11 years) of their relationships with teachers, other adults and children. Data were collected via an attitudinal questionnaire survey in nine primary schools in England. Results indicate that, in addition to the development of social skills, children also valued academic confidence, learning and the involvement of their parents in homework, and that these were associated with the interactions and routines established within the primary classroom settings. Some variations in terms of pupil age, teacher career phase, and the socio-economic context of the school were identified; however, the importance of the relationship between pupil and teacher remained consistent across schools.
