The social determinants of chronic disease management: perspectives of elderly patients with hypertension from low socio-economic background in Singapore
Background In Singapore, the burden of hypertension disproportionately falls on the elderly population of low socio-economic status. Despite availability of effective treatment, studies have shown high prevalence of sub-optimal blood pressure control in this group. Poor hypertension management can be attributed to a number of personal factors including awareness, management skills and overall adherence to treatment. However, these factors are also closely linked to a broader range of community and policy factors. This paper explores the perceived social and physical environments of low socio-economic status and elderly patients with hypertension; and how the interplay of factors within these environments influences their ability to mobilise resources for hypertension management. Methods In-depth interviews were conducted in English, Chinese, Chinese dialects and Malay with 20 hypertensive patients of various ethnic backgrounds. Purposive sampling was adopted for recruitment of participants from a previous community health screening campaign. Interviews were translated into English and transcribed verbatim. We deductively analysed leveraging on the Social Model of Health to identify key themes, while inductive analysis was used simultaneously to allow sub-themes to emerge. Results and discussion Our finding shows that financing is an overarching topic embedded in most themes. Despite the availability of multiple safety nets, some patients were left out and lacked capital to navigate systems effectively, which resulted in delayed treatment or debt. The built environment played a significant role in enabling patients to access care easily and lead a more active lifestyle. A closer look is needed to enhance the capacity of patients with mobility challenges to enjoy equitable access. Furthermore, the establishment of community based elderly centres has enabled patients to engage in meaningful and healthy social activities. In contrast, participants' descriptions showed that their communication with healthcare professionals remained brief, and that personalised and meaningful interactions that are context and culturally specific are essential to advocate for patients' overall treatment adherence and lifestyle modification. Conclusion Elderly patients with hypertension from lower socio-economic background have various unmet needs in managing their hypertension and other comorbidities. These needs are closely related to broader societal factors such as socio-demographic characteristics, support systems, urban planning and public policies, and health systems factors. Policy decisions to address these needs require an integrated multi-sectoral approach grounded in the principles of health equity.This research was supported by MOE TIER - 1 FUND R-608-000-133-112 and the National University Health System (NUHS) Singapore Population Health Improvement Centre (SPHERiC)
Community participation in health services development, implementation, and evaluation: A systematic review of empowerment, health, community, and process outcomes.
BACKGROUND: Community participation is widely believed to be beneficial to the development, implementation and evaluation of health services. However, many challenges to successful and sustainable community involvement remain. Importantly, there is little evidence on the effect of community participation in terms of outcomes at both the community and individual level. Our systematic review seeks to examine the evidence on outcomes of community participation in high and upper-middle income countries. METHODS AND FINDINGS: This review was developed according to PRISMA guidelines. Eligible studies included those that involved the community, service users, consumers, households, patients, public and their representatives in the development, implementation, and evaluation of health services, policy or interventions. We searched the following databases from January 2000 to September 2016: Medline, Embase, Global Health, Scopus, and LILACs. We independently screened articles for inclusion, conducted data extraction, and assessed studies for risk of bias. No language restrictions were made. 27,232 records were identified, with 23,468 after removal of duplicates. Following titles and abstracts screening, 49 met the inclusion criteria for this review. A narrative synthesis of the findings was conducted. Outcomes were categorised as process outcomes, community outcomes, health outcomes, empowerment and stakeholder perspectives. Our review reports a breadth of evidence that community involvement has a positive impact on health, particularly when substantiated by strong organisational and community processes. This is in line with the notion that participatory approaches and positive outcomes including community empowerment and health improvements do not occur in a linear progression, but instead consists of complex processes influenced by an array of social and cultural factors. CONCLUSION: This review adds to the evidence base supporting the effectiveness of community participation in yielding positive outcomes at the organizational, community and individual level.

Barriers and enablers to the implementation of the 6-PACK falls prevention program: A preimplementation study in hospitals participating in a cluster randomised controlled trial
Evidence for effective falls prevention interventions in acute wards is limited. One reason for this may be suboptimal program implementation. This study aimed to identify perceived barriers and enablers of the implementation of the 6-PACK falls prevention program to inform the implementation in a randomised controlled trial. Strategies to optimise successful implementation of 6-PACK were also sought. A mixed-methods approach was applied in 24 acute wards from 6 Australian hospitals. Participants were nurses working on participating wards and senior hospital staff including Nurse Unit Managers; senior physicians; Directors of Nursing; and senior personnel involved in quality and safety or falls prevention. Information on barriers and enablers of 6-PACK implementation was obtained through surveys, focus groups and interviews. Questions reflected the COM-B framework that includes three behaviour change constructs of: capability, opportunity and motivation. Focus group and interview data were analysed thematically, and survey data descriptively. The survey response rate was 60% (420/702), and 12 focus groups (n = 96 nurses) and 24 interviews with senior staff were conducted. Capability barriers included beliefs that falls could not be prevented; and limited knowledge on falls prevention in patients with complex care needs (e.g. cognitive impairment). Capability enablers included education and training, particularly face to face case study based approaches. Lack of resources was identified as an opportunity barrier. Leadership, champions and using data to drive practice change were recognised as opportunity enablers. Motivation barriers included complacency and lack of ownership in falls prevention efforts. Motivation enablers included senior staff articulating clear goals and a commitment to falls prevention; and use of reminders, audits and feedback. The information gained from this study suggests that regular practical face-to-face education and training for nurses; provision of equipment; audit, reminders and feedback; leadership and champions; and the provision of falls data is key to successful falls prevention program implementation in acute hospitals
Building a values-based culture in nurse education
Nurse education has found itself challenged to select and educate nurses who on completion of? of their programme? have: excellent technical skills, an ability to critically analyse care and work compassionately in ways that support the values of care that are important to service users. Recent reports of care suggest that nursing still needs to develop the values base of its student selection and education processes. Against this backdrop, this paper presents two examples from pre registration nurse education that illustrate how a values based approach is used as part of the selection process in one university and used to inform the development of a reflective poetry initiative in another university.
Having presented the two examples the authors debate some of the wider benefits and challenges linked to these ways of working. For example, the importance of connecting nurses’ personal beliefs, attitudes and assumptions to service user values in recruitment are discussed. The use of poetry as a way of thinking about practice that moves beyond traditional models of reflection in nursing are also considered. However, the authors recognise that if developments in nurse education are to have a real impact on nursing practice and patient care, there is the need for values based initiatives to be more directly connected to the delivery of healthcare
Methodologies for Assessing the Acceptability of Oral Formulations among children and older adults: A Systematic Review
This is an open access article distributed under the terms and conditions of the Creative Commons Attribution NonCommercial-NoDerivatives 4.0 International CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/Acceptability of medicinal products in children and older populations is pivotal in ensuring adherence and therapeutic outcomes. This review systematically identifies studies reporting on formulation aspects of oral medications that affect their acceptability in these patient groups. Particular emphasis is placed on the evaluation of the methodologies employed in the studies. Sixty-eight studies were included for analysis, with 51 (75%) in children and 17 (25%) in older populations. The studies evaluated a range of oral formulations; however, the methodologies used differ considerably in participants’ characteristics, study settings, tools, acceptability definitions and criteria. It is evident that there is a lack of standardisation in study design as well as the assessment methods used in assessing acceptability of medicines in children and older populations. This review presents a systematic analysis on methods employed for assessing acceptability of oral medicines in children and older adults, to provide insights and recommendations regarding the design of reliable instruments in future studies.Peer reviewe
Imaging biomarker roadmap for cancer studies.
Imaging biomarkers (IBs) are integral to the routine management of patients with cancer. IBs used daily in oncology include clinical TNM stage, objective response and left ventricular ejection fraction. Other CT, MRI, PET and ultrasonography biomarkers are used extensively in cancer research and drug development. New IBs need to be established either as useful tools for testing research hypotheses in clinical trials and research studies, or as clinical decision-making tools for use in healthcare, by crossing 'translational gaps' through validation and qualification. Important differences exist between IBs and biospecimen-derived biomarkers and, therefore, the development of IBs requires a tailored 'roadmap'. Recognizing this need, Cancer Research UK (CRUK) and the European Organisation for Research and Treatment of Cancer (EORTC) assembled experts to review, debate and summarize the challenges of IB validation and qualification. This consensus group has produced 14 key recommendations for accelerating the clinical translation of IBs, which highlight the role of parallel (rather than sequential) tracks of technical (assay) validation, biological/clinical validation and assessment of cost-effectiveness; the need for IB standardization and accreditation systems; the need to continually revisit IB precision; an alternative framework for biological/clinical validation of IBs; and the essential requirements for multicentre studies to qualify IBs for clinical use.Development of this roadmap received support from Cancer Research UK and the Engineering and Physical Sciences Research Council (grant references A/15267, A/16463, A/16464, A/16465, A/16466 and A/18097), the EORTC Cancer Research Fund, and the Innovative Medicines Initiative Joint Undertaking (grant agreement number 115151), resources of which are composed of financial contribution from the European Union's Seventh Framework Programme (FP7/2007-2013) and European Federation of Pharmaceutical Industries and Associations (EFPIA) companies' in kind contribution

Case Reports1. A Late Presentation of Loeys-Dietz Syndrome: Beware of TGFβ Receptor Mutations in Benign Joint Hypermobility
Background: Thoracic aortic aneurysms (TAA) and dissections are not uncommon causes of sudden death in young adults. Loeys-Dietz syndrome (LDS) is a rare, recently described, autosomal dominant, connective tissue disease characterized by aggressive arterial aneurysms, resulting from mutations in the transforming growth factor beta (TGFβ) receptor genes TGFBR1 and TGFBR2. Mean age at death is 26.1 years, most often due to aortic dissection. We report an unusually late presentation of LDS, diagnosed following elective surgery in a female with a long history of joint hypermobility. Methods: A 51-year-old Caucasian lady complained of chest pain and headache following a dural leak from spinal anaesthesia for an elective ankle arthroscopy. CT scan and echocardiography demonstrated a dilated aortic root and significant aortic regurgitation. MRA demonstrated aortic tortuosity, an infrarenal aortic aneurysm and aneurysms in the left renal and right internal mammary arteries. She underwent aortic root repair and aortic valve replacement. She had a background of long-standing joint pains secondary to hypermobility, easy bruising, unusual fracture susceptibility and mild bronchiectasis. She had one healthy child age 32, after which she suffered a uterine prolapse. Examination revealed mild Marfanoid features. Uvula, skin and ophthalmological examination was normal. Results: Fibrillin-1 testing for Marfan syndrome (MFS) was negative. Detection of a c.1270G > C (p.Gly424Arg) TGFBR2 mutation confirmed the diagnosis of LDS. Losartan was started for vascular protection. Conclusions: LDS is a severe inherited vasculopathy that usually presents in childhood. It is characterized by aortic root dilatation and ascending aneurysms. There is a higher risk of aortic dissection compared with MFS. Clinical features overlap with MFS and Ehlers Danlos syndrome Type IV, but differentiating dysmorphogenic features include ocular hypertelorism, bifid uvula and cleft palate. Echocardiography and MRA or CT scanning from head to pelvis is recommended to establish the extent of vascular involvement. Management involves early surgical intervention, including early valve-sparing aortic root replacement, genetic counselling and close monitoring in pregnancy. Despite being caused by loss of function mutations in either TGFβ receptor, paradoxical activation of TGFβ signalling is seen, suggesting that TGFβ antagonism may confer disease modifying effects similar to those observed in MFS. TGFβ antagonism can be achieved with angiotensin antagonists, such as Losartan, which is able to delay aortic aneurysm development in preclinical models and in patients with MFS. Our case emphasizes the importance of timely recognition of vasculopathy syndromes in patients with hypermobility and the need for early surgical intervention. It also highlights their heterogeneity and the potential for late presentation. Disclosures: The authors have declared no conflicts of interes
