Abstract
INTRODUCTION Abdominal wall reconstruction (AWR) is an emerging subspecialty within general surgery. The practice of multidisciplinary team (MDT) meetings to aid decision making and improve patient care has been demonstrated, with widespread acceptance. This study presents our initial experience of over 150 cases of complex hernia patients discussed in a newly established MDT setting. METHODS From February 2020 to July 2022 (30-month period), abdominal wall MDTs were held bimonthly. Key stakeholders included upper and lower gastrointestinal surgeons, a gastrointestinal specialist radiologist, a plastic surgeon, a high-risk anaesthetist and two junior doctors integrated into the AWR clinical team. Meetings were held online, where patient history, past medical and surgical history, hernia characteristics and up-to-date computed tomography scans were discussed. RESULTS Some 156 patients were discussed over 18 meetings within the above period. Ninety-five (61%) patients were recommended for surgery, and 61 (39%) patients were recommended for conservative management or referred elsewhere. Seventy-eight (82%) patients were directly waitlisted, whereas seventeen (18%) required preoperative optimisation: three (18%) for smoking cessation, eleven (65%) for weight-loss management and three (18%) for specialist diabetic assessment and management. In total, 92 (59%) patients (including operative and nonoperative management) have been discharged to primary care. DISCUSSION A multidisciplinary forum for complex abdominal wall patients is a safe process that facilitates decision making, promotes education and improves patient care. As the AWR subspecialty evolves, our view is that the "complex hernia MDT" will become commonplace. We present our experience and share advice for others planning to establish an AWR centre.

Abstract
BACKGROUND Acute hospitalisation and delirium have individually been shown to adversely affect trajectories of cognitive decline but have not previously been considered together. This work aimed to explore the impact on cognition of hospital admission with and without delirium, compared to a control group with no hospital admissions. METHODS The Delirium and Cognitive Impact in Dementia (DECIDE) study was nested within the Cognitive Function and Ageing Study II (CFAS II)-Newcastle cohort. CFAS II participants completed two baseline interviews, including the Mini-Mental State Examination (MMSE). During 2016, surviving participants from CFAS II-Newcastle were recruited to DECIDE on admission to hospital. Participants were reviewed daily to determine delirium status.During 2017, all DECIDE participants and age, sex and years of education matched controls without hospital admissions during 2016 were invited to repeat the CFAS II interview. Delirium was excluded in the control group using the Informant Assessment of Geriatric Delirium Scale (i-AGeD). Linear mixed effects modelling determined predictors of cognitive decline. RESULTS During 2016, 82 of 205 (40%) DECIDE participants had at least one episode of delirium. At 1 year, 135 of 205 hospitalised participants completed an interview along with 100 controls. No controls experienced delirium (i-AGeD>4). Delirium was associated with a faster rate of cognitive decline compared to those without delirium (β = -2.2, P < 0.001), but number of hospital admissions was not (P = 0.447). CONCLUSIONS These results suggest that delirium during hospitalisation rather than hospitalisation per se is a risk factor for future cognitive decline, emphasising the need for dementia prevention studies that focus on delirium intervention.

Abstract
BACKGROUND Primary and incisional ventral hernia trials collect unstandardized inconsistent data, limiting data interpretation and comparison. This study aimed to create two minimum data sets for primary and incisional ventral hernia interventional trials to standardize data collection and improve trial comparison. To support these data sets, standardized patient-reported outcome measures and trial methodology criteria were created. METHODS To construct these data sets, nominal group technique methodology was employed, involving 15 internationally recognized abdominal wall surgeons and two patient representatives. Initially a maximum data set was created from previous systematic and panellist reviews. Thereafter, three stages of voting took place: stage 1, selection of the number of variables for data set inclusion; stage 2, selection of variables to be included; and stage 3, selection of variable definitions and detection methods. A steering committee interpreted and analysed the data. RESULTS The maximum data set contained 245 variables. The three stages of voting commenced in October 2019 and had been completed by July 2020. The final primary ventral hernia data set included 32 variables, the incisional ventral hernia data set included 40 variables, the patient-reported outcome measures tool contained 25 questions, and 40 methodological criteria were chosen. The best known variable definitions were selected for accurate variable description. CT was selected as the optimal preoperative descriptor of hernia morphology. Standardized follow-up at 30 days, 1 year, and 5 years was selected. CONCLUSION These minimum data sets, patient-reported outcome measures, and methodological criteria have allowed creation of a manual for investigators aiming to undertake primary ventral hernia or incisional ventral hernia interventional trials. Adopting these data sets will improve trial methods and comparisons.

Abstract
Background Delirium is common, distressing and associated with poor outcomes. Previous studies investigating the impact of delirium on cognitive outcomes have been limited by incomplete ascertainment of baseline cognition or lack of prospective delirium assessments. This study quantified the association between delirium and cognitive function over time by prospectively ascertaining delirium in a cohort aged ≥ 65 years in whom baseline cognition had previously been established. Methods For 12 months, we assessed participants from the Cognitive Function and Ageing Study II-Newcastle for delirium daily during hospital admissions. At 1-year, we assessed cognitive decline and dementia in those with and without delirium. We evaluated the effect of delirium (including its duration and number of episodes) on cognitive function over time, independently of baseline cognition and illness severity. Results Eighty two of 205 participants recruited developed delirium in hospital (40%). One-year outcome data were available for 173 participants: 18 had a new dementia diagnosis, 38 had died. Delirium was associated with cognitive decline (−1.8 Mini-Mental State Examination points [95% CI –3.5 to –0.2]) and an increased risk of new dementia diagnosis at follow up (OR 8.8 [95% CI 1.9–41.4]). More than one episode and more days with delirium (>5 days) were associated with worse cognitive outcomes. Conclusions Delirium increases risk of future cognitive decline and dementia, independent of illness severity and baseline cognition, with more episodes associated with worse cognitive outcomes. Given that delirium has been shown to be preventable in some cases, we propose that delirium is a potentially modifiable risk factor for dementia.

Abstract
BACKGROUND Ventra hernias are increasing in prevalence and many recur despite attempted repair. To date, much of the literature is underpowered and divergent. As a result there is limited high quality evidence to inform surgeons succinctly which perioperative variables influence postoperative recurrence. This systematic review aimed to identify predictors of ventral hernia recurrence. METHODS PubMed was searched for studies reporting prognostic data of ventral hernia recurrence between 1 January 1995 and 1 January 2018. Extracted data described hernia type (primary/incisional), definitions of recurrence, methods used to detect recurrence, duration of follow-up, and co-morbidity. Data were extracted for all potential predictors, estimates and thresholds described. Random-effects meta-analysis was used. Bias was assessed with a modified PROBAST (Prediction model Risk Of Bias ASsessment Tool). RESULTS Screening of 18 214 abstracts yielded 274 individual studies for inclusion. Hernia recurrence was defined in 66 studies (24.1 per cent), using 41 different unstandardized definitions. Three patient variables (female sex, age 65 years or less, and BMI greater than 25, 30, 35 or 40 kg/m2), five patient co-morbidities (smoking, diabetes, chronic obstructive pulmonary disease, ASA grade III-IV, steroid use), two hernia-related variables (incisional/primary, recurrent/primary), six intraoperative variables (biological mesh, bridged repair, open versus laparoscopic surgery, suture versus mesh repair, onlay/retrorectus, intraperitoneal/retrorectus), and six postoperative variables (any complication, surgical-site occurrence, wound infection, seroma, haematoma, wound dehiscence) were identified as significant prognostic factors for hernia recurrence. CONCLUSION This study summarized the current evidence base for predicting ventral hernia recurrence. Results should inform best practice and future research.

Abstract
INTRODUCTION Abdominal wall herniation (AWH) is an increasing problem for patients, surgeons, and healthcare providers. Surgical-site specific outcomes, such as infection, recurrence, and mesh explantation, are improving; however, successful repair still exposes the patient to what is often a complex major operation aimed at improving quality of life. Quality-of-life (QOL) outcomes, such as aesthetics, pain, and physical and emotional functioning, are less often and less well reported. We reviewed QOL tools currently available to evaluate their suitability. METHODS A systematic review of the literature in compliance with PRISMA guidelines was performed between 1st January 1990 and 1st May 2019. English language studies using validated quality-of-life assessment tool, whereby outcomes using this tool could be assessed were included. RESULTS Heterogeneity in the QOL tool used for reporting outcome was evident throughout the articles reviewed. AWH disease-specific tools, hernia-specific tools, and generic tools were used throughout the literature with no obviously preferred or dominant method identified. CONCLUSION Despite increasing acknowledgement of the need to evaluate QOL in patients with AWH, no tool has become dominant in this field. Assessment, therefore, of the impact of certain interventions or techniques on quality of life remains difficult and will continue to do so until an adequate standardised outcome measurement tool is available.

Abstract
BACKGROUND Nomenclature for mesh insertion during ventral hernia repair is inconsistent and confusing. Several terms, including 'inlay', 'sublay' and 'underlay', can refer to the same anatomical planes in the indexed literature. This frustrates comparisons of surgical practice and may invalidate meta-analyses comparing surgical outcomes. The aim of this study was to establish an international classification of abdominal wall planes. METHODS A Delphi study was conducted involving 20 internationally recognized abdominal wall surgeons. Different terms describing anterior abdominal wall planes were identified via literature review and expert consensus. The initial list comprised 59 possible terms. Panellists completed a questionnaire that suggested a list of options for individual abdominal wall planes. Consensus on a term was predefined as occurring if selected by at least 80 per cent of panellists. Terms scoring less than 20 per cent were removed. RESULTS Voting started August 2018 and was completed by January 2019. In round 1, 43 terms (73 per cent) were selected by less than 20 per cent of panellists and 37 new terms were suggested, leaving 53 terms for round 2. Four planes reached consensus in round 2, with the terms 'onlay', 'inlay', 'preperitoneal' and 'intraperitoneal'. Thirty-five terms (66 per cent) were selected by less than 20 per cent of panellists and were removed. After round 3, consensus was achieved for 'anterectus', 'interoblique', 'retro-oblique' and 'retromuscular'. Default consensus was achieved for the 'retrorectus' and 'transversalis fascial' planes. CONCLUSION Consensus concerning abdominal wall planes was agreed by 20 internationally recognized surgeons. Adoption should improve communication and comparison among surgeons and research studies.

Abstract
Background Acquiring medical competencies alone does not necessarily lead to the delivery of quality clinical care. Many UK training programs are soon to be based on the curricula of entrustable professional capabilities (EPCs). These are tasks carried out in practice requiring proficiency in several competencies for quality practice. Assessments to evaluate EPCs for independent practice are needed. Comprehensive geriatric assessment (CGA) is an EPC in geriatric medicine. We describe the development of an assessment of CGA as an example of examining EPCs. Methods A CGA station was introduced in the Diploma in Geriatric Medicine clinical examination. Candidates rotate through four stations: three single competency-based stations (history, communication/ethics and physical examination) and an EPC-based station in CGA. Results One hundred and seventy-eight (female: 96 [53.9%]) candidates took it. There was a weak but significantly positive correlation between the score at CGA and the total score in the other stations (r = 0.46; P < 0.001). Most candidates passing the station passed the examination. Correlation with other stations similarly showed weak significant correlations (Station 1: r = 0.38; P < 0.001, Station 3: r = 0.28; P < 0.001, and Station 4: r = 0.37; P < 0.001). There was 61.4% (kappa: 0.61; P = 0.000) agreement between examiners whether a candidate passed or failed. Agreement was higher for the other stations, i.e. Station 1 (kappa: 0.85; P < 0.001), Station 3 (kappa: 0.72; P < 0.001), and Station 4 (kappa: 0.85; P < 0.001). Discussion Performance on the station correlated positively with overall performance, suggesting that it has discriminatory value in differentiating candidates with varying ability and the more able candidates pass the examination.

Abstract
BACKGROUND Frailty is a significant determinant of health care utilisation and associated costs, both of which also increase with proximity to death. What is not known is how the relationships between frailty, proximity to death, hospital use and costs develop in a population aged 85 years and over. METHODS This study used data from a prospective observational cohort, the Newcastle 85+ Study, linked with hospital episode statistics and death registrations. Using the Rockwood frailty index (cut off <0.25), we analysed the relationship between frailty and mortality, proximity to death, hospital use and hospital costs over 2, 5 and 7 years using descriptive statistics, Kaplan-Meier survival curves, Cox's proportional hazards and negative binomial regression models. RESULTS Baseline frailty was associated with a more than two-fold increased risk of mortality after 7 years, compared to people who were non-frail. Participants classified as frail spent more time in hospital over 7 years than the non-frail, but this difference declined over time. Baseline frailty was not associated with increased time spent in hospital during the last 90 days of life. CONCLUSION Evidence continues to accrue on the impact of frailty on emergency health care use. Hospital and community services need to adapt to meet the challenge of introducing new proactive and preventative approaches, designed to achieve benefits in clinical and/or cost effectiveness of frailty management.

Abstract
BACKGROUND Ventral hernias (VHs) often recur after surgical repair and subsequent attempts at repair are especially challenging. Rigorous research to reduce recurrence is required but such studies must be well-designed and report representative and comprehensive outcomes. OBJECTIVE We aimed to assesses methodological quality of non-randomised interventional studies of VH repair by systematic review. METHODS We searched the indexed literature for non-randomised studies of interventions for VH repair, January 1995 to December 2017 inclusive. Each prospective study was coupled with a corresponding retrospective study using pre-specified criteria to provide matched, comparable groups. We applied a bespoke methodological tool for hernia trials by combining relevant items from existing published tools. Study introduction and rationale, design, participant inclusion criteria, reported outcomes, and statistical methods were assessed. RESULTS Fifty studies (17,608 patients) were identified: 25 prospective and 25 retrospective. Overall, prospective studies scored marginally higher than retrospective studies for methodological quality, median score 17 (IQR: 14-18) versus 15 (IQR 12-18), respectively. For the sub-categories investigated, prospective studies achieved higher median scores for their, 'introduction', 'study design' and 'participants'. Surprisingly, no study stated that a protocol had been written in advance. Only 18 (36%) studies defined a primary outcome, and only 2 studies (4%) described a power calculation. No study referenced a standardised definition for VH recurrence and detection methods for recurrence varied widely. Methodological quality did not improve with publication year or increasing journal impact factor. CONCLUSION Currently, non-randomised interventional studies of VH repair are methodologically poor. Clear outcome definitions and a standardised minimum dataset are needed.

Abstract
INTRODUCTION multiple conditions in later life (multi-morbidity) is a major challenge for health and care systems worldwide, is of particular relevance for older people, but has not (until recently) received high priority as a topic for research. We have identified the top 10 research priorities from the perspective of older people, their carers, and health and social care professionals using the methods of a James Lind Alliance Priority Setting Partnership. METHODS in total, 354 participants (162 older people and carers, 192 health professionals) completed a survey and 15 older people and carers were interviewed to produce 96 'unanswered questions'. These were further refined by survey and interviews to a shortlist of 21 topics, and a mix of people aged 80+ living with three or more conditions, carers and health and social care providers to prioritised the top 10. RESULTS the key priorities were about the prevention of social isolation, the promotion of independence and physical and emotional well-being. In addition to these broad topics, the process also identified detailed priorities including the role of exercise therapy, the importance of falls (particularly fear of falling), the recognition and management of frailty and Comprehensive Geriatric Assessment. CONCLUSION these topics provide a unique perspective on research priorities on multiple conditions in later life and complement existing UK and International recommendations about the optimisation of health and social care systems to deliver essential holistic models of care and the prevention and treatment of multiple co-existing conditions.

Abstract
BACKGROUND Older people with an acute illness, many of whom are also frail, form a significant proportion of the acute hospital inpatient population. Attention is focusing on ways of improving the physical environment to optimize health outcomes and staff efficiency. PURPOSE This article explores the effects of the physical environment in three acute care settings: acute hospital site, in-patient rehabilitation hospital, and intermediate care provision (a nursing home with some beds dedicated to intermediate care) chosen to represent different steps on the acute care pathway for older people and gain the perspectives of patients, family carers, and staff. METHODS Semi structured interviews were undertaken with 40 patient/carer dyads (where available) and three staff focus groups were conducted in each care setting with a range of staff. RESULTS Multiple aspects of the physical environment were reported as important by patients, family carers, and staff. For example, visitors stressed the importance of access and parking, patients valued environments where privacy and dignity were protected, storage space was poor across all sites, and security was important to patients but visitors want easy access to wards. CONCLUSIONS The physical environment is a significant component of acute care for older people, many of whom are also frail, but often comes second to organization of care, or relationships between actors in an episode of care.

Abstract
Ventral hernia disease is becoming increasingly prevalent and complex. Subspecialisation for patients with challenging conditions requiring surgery has been shown to improve postoperative outcomes. Worldwide, there is an emergence of specialist hernia centres using new and innovative techniques to repair large and complicated ventral hernias. After a national meeting of hernia experts, we present an algorithm to be used as a national triage system for patients with ventral hernias, with the aim of ensuring that patients are operated on by the most appropriate surgeon. Evidence-based clinical risk factors and ventral hernia parameters are used for risk stratification and patient triage. We hope that this algorithm will guide future ventral hernia management in the UK.

Abstract
Background Comprehensive Geriatric Assessment (CGA) is now the accepted gold standard for caring for frail older people in hospital. However, there is uncertainty about identifying and targeting suitable recipients and which patients benefit the most. Objectives our objectives were to describe the key elements, principal measures of outcome and the characteristics of the main beneficiaries of inpatient CGA. Methods we used the Joanna Briggs Institute umbrella review method. We searched for systematic reviews and meta-analyses describing CGA services for hospital inpatients in the Cochrane Database of Systematic Reviews, Database of Reviews of Effectiveness (DARE), MEDLINE and EMBASE and a range of other sources. Results we screened 1,010 titles and evaluated 419 abstracts for eligibility, 143 full articles for relevance and included 24 in a final quality and relevance check. Thirteen reviews, reported in 15 papers, were selected for review. The most widely used definition of CGA was: 'a multidimensional, multidisciplinary process which identifies medical, social and functional needs, and the development of an integrated/co-ordinated care plan to meet those needs'. Key clinical outcomes included mortality, activities of daily living and dependency. The main beneficiaries were people ≥55 years in receipt of acute care. Frailty in CGA recipients and patient related outcomes were not usually reported. Conclusions we confirm a widely used definition of CGA. Key outcomes are death, disability and institutionalisation. The main beneficiaries in hospital are older people with acute illness. The presence of frailty has not been widely examined as a determinant of CGA outcome.

Abstract
In this article, we discuss the emergence of new models for delivery of comprehensive geriatric assessment (CGA) in the acute hospital setting. CGA is the core technology of Geriatric Medicine and for hospital inpatients it improves key outcomes such as survival, time spent at home and institutionalisation. Traditionally It is delivered by specialised multidisciplinary teams, often in dedicated wards, but in recent years has begun to be taken up and developed quite early in the admission process (at the 'front door'), across traditional ward boundaries and in specialty settings such as surgical and pre-operative care, and oncology. We have scanned recent literature, including observational studies of service evaluations, and service descriptions presented as abstracts of conference presentations to provide an overview of an emerging landscape of innovation and development in CGA services for hospital inpatients.

Abstract
The prevalence of urinary incontinence (UI) increases with age and can negatively affect quality of life. However, relatively few older people with UI seek treatment. The aim of this study was to explore the views of older people with UI on the process of seeking help. Older people with UI were recruited to the study from three continence services in the north of England: a geriatrician-led hospital outpatient clinic (n = 18), a community-based nurse-led service (n = 22) and a consultant gynaecologist-led service specialising in surgical treatment (n = 10). Participants took part in semi-structured interviews, which were transcribed and underwent thematic content analysis. Three main themes emerged: Being brushed aside, in which participants expressed the feeling that general practitioners did not prioritise or recognise their concerns; Putting up with it, in which participants delayed seeking help for their UI due to various reasons including embarrassment, the development of coping mechanisms, perceiving UI as a normal part of the ageing process, or being unaware that help was available; and Something has to be done, in which help-seeking was prompted by the recognition that their UI was a serious problem, whether as a result of experiencing UI in public, the remark of a relative, the belief that they had a serious illness or the detection of UI during comprehensive geriatric assessment. Greater awareness that UI is a treatable condition and not a normal part of ageing is needed in the population and among health professionals. Comprehensive geriatric assessment appeared an important trigger for referral and treatment in our participants. Screening questions by healthcare professionals could be a means to identify, assess and treat older people with UI.

Abstract
INTRODUCTION Genome-Wide Association Studies have identified associations between lung function measures and Chronic Obstructive Pulmonary Disease (COPD) and chromosome region 6p21 containing the gene for the Advanced Glycation End Product Receptor (AGER, encoding RAGE). We aimed to (i) characterise RAGE expression in the lung, (ii) identify AGER transcripts, (iii) ascertain if SNP rs2070600 (Gly82Ser C/T) is associated with lung function and serum sRAGE levels and (iv) identify whether the Gly82Ser variant is functionally important in altering sRAGE levels in an airway epithelial cell model. METHODS Immunohistochemistry was used to identify RAGE protein expression in 26 human tissues and qPCR was used to quantify AGER mRNA in lung cells. Gene expression array data was used to identify AGER expression during lung development in 38 fetal lung samples. RNA-Seq was used to identify AGER transcripts in lung cells. sRAGE levels were assessed in cells and patient serum by ELISA. BEAS2B-R1 cells were transfected to overexpress RAGE protein with either the Gly82 or Ser82 variant and sRAGE levels identified. RESULTS Immunohistochemical assessment of 6 adult lung samples identified high RAGE expression in the alveoli of healthy adults and individuals with COPD. AGER/RAGE expression increased across developmental stages in human fetal lung at both the mRNA (38 samples) and protein levels (20 samples). Extensive AGER splicing was identified. The rs2070600T (Ser82) allele is associated with higher FEV1, FEV1/FVC and lower serum sRAGE levels in UK smokers. Using an airway epithelium model overexpressing the Gly82 or Ser82 variants we found that HMGB1 activation of the RAGE-Ser82 receptor results in lower sRAGE production. CONCLUSIONS This study provides new information regarding the expression profile and potential role of RAGE in the human lung and shows a functional role of the Gly82Ser variant. These findings advance our understanding of the potential mechanisms underlying COPD particularly for carriers of this AGER polymorphism.

Abstract
Background Several regions of the genome have shown to be associated with COPD in genome-wide association studies of common variants. Objective To determine rare and potentially functional single nucleotide polymorphisms (SNPs) associated with the risk of COPD and severity of airflow limitation. Methods 3226 current or former smokers of European ancestry with lung function measures indicative of Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2 COPD or worse were genotyped using an exome array. An analysis of risk of COPD was carried out using ever smoking controls (n=4784). Associations with %predicted FEV1 were tested in cases. We followed-up signals of interest (p<10−5) in independent samples from a subset of the UK Biobank population and also undertook a more powerful discovery study by meta-analysing the exome array data and UK Biobank data for variants represented on both arrays. Results Among the associated variants were two in regions previously unreported for COPD; a low frequency non-synonymous SNP in MOCS3 (rs7269297, pdiscovery=3.08×10−6, preplication=0.019) and a rare SNP in IFIT3, which emerged in the meta-analysis (rs140549288, pmeta=8.56×10−6). In the meta-analysis of % predicted FEV1 in cases, the strongest association was shown for a splice variant in a previously unreported region, SERPINA12 (rs140198372, pmeta=5.72×10−6). We also confirmed previously reported associations with COPD risk at MMP12, HHIP, GPR126 and CHRNA5. No associations in novel regions reached a stringent exome-wide significance threshold (p<3.7×10−7). Conclusions This study identified several associations with the risk of COPD and severity of airflow limitation, including novel regions MOCS3, IFIT3 and SERPINA12, which warrant further study.

Abstract
Background and designThis research was based on a reanalysis of a merged data set from two intermediate care (IC) projects in order to identify patient characteristics associated with outcomes [Nancarrow SA, Enderby PM, Moran AM, Dixon S, Parker SG, Bradburn MJ,et al.The Relationship Between Workforce Flexibility and the Costs and Outcomes of Older Peoples’ Services (COOP). Southampton: National Institute for Health Research (NIHR) Service Delivery and Organisation (SDO); 2010 and Nancarrow SA, Enderby PM, Ariss SM, Smith T, Booth A, Campbell MJ,et al.The Impact of Enhancing the Effectiveness of Interdisciplinary Working (EEICC). Southampton: NIHR SDO; 2012]. Additionally, the impact of different team and staffing structures on patient outcomes and service costs was examined, when possible given the data sets, to enable identification of the most cost-effective service configurations and change over time with service provision. This secondary analysis was placed within updated literature reviews focused on the separate questions.Research objectives(1) To identify those patients most likely to benefit from IC and those who would be best placed to receive care elsewhere; (2) to examine the effectiveness of different models of IC; (3) to explore the differences between IC service configurations and how they have changed over time; and (4) to use the findings above to develop accessible evidence to guide service commissioning and monitoring.SettingCommunity-based services for older people are described in many different ways, among which are IC services and community rehabilitation. For the purposes of this report we call the services IC services and include all community-based provision for supporting older people who would otherwise be admitted to hospital or who would require increased length of stay in hospital (e.g. hospital at home schemes, post-acute care, step-up and step-down services).ParticipantsThe combined data set contained data on 8070 patient admissions from 32 IC teams across England and included details of the service context, costs, staffing/skill mix (800 staff), patient health status and outcomes.InterventionsThe interventions associated with the study cover the range of services and therapies available in IC settings. These are provided by a wide range of professionals and care staff, including nursing, allied health and social care.Outcome measures(1) Service data – each team provided information relating to the size, nature, staffing and resourcing of the services. Data were collected on a service pro forma. (2) Team data – all staff members of the teams participating in both studies provided individual information using the Workforce Dynamics Questionnaire. (3) Patient data – patient data were collected on admission and discharge using a client record pack. The client record pack recorded a range of data utilising a number of validated tools, such as demographic data, level of care (LoC) data, therapy outcome measure (TOM) scale, European Quality of Life-5 Dimensions (EQ-5D) questionnaire and patient satisfaction survey.Results(1) The provision of IC across England is highly variable with different referral routes, team structures, skill mix and cost-effectiveness; (2) in more recent years, patients referred to IC have more complex needs associated with more severe impairments; (3) patients most likely to improve were those requiring rehabilitation as determined by levels 3, 4 and 5 on the LoC (> 40% for impairment, activity and participation, and > 30% for well-being as determined on the TOM scale); (4) half of all patients with outcome data improved on at least one of the domains of the TOM scale; (5) for every 10-year increase in age there was a 6% decrease in the odds of returning home. The chance of remaining or returning home was greater for females than males; (6) a high percentage of patients referred to IC do not require the service; and (7) teams including clinical support staff and domiciliary staff were associated with a small relative improvement in TOM impairment scores when compared with other teams.ConclusionsThis study provides additional evidence that interdisciplinary teamworking in IC may be associated with better outcomes for patients, but care should be taken with overinterpretation. The measures that were used within the studies were found to be reliable, valid and practical and could be used for benchmarking. This study highlights the need for funding high-quality studies that attempt to examine what specific team-level factors are associated with better outcomes for patients. It is therefore important that studies in the future attempt empirically to examine what process-level team variables are associated with these outcomes.FundingThe NIHR Health Services and Delivery Research programme.

Abstract
BACKGROUND The increasing prevalence and associated cost of treating chronic obstructive pulmonary disease (COPD) is unsustainable, and focus is needed on self-management and prevention of hospital admissions. Telehealth monitoring of patients' vital signs allows clinicians to prioritise their workload and enables patients to take more responsibility for their health. This paper reports the results of a pilot randomised controlled trial (RCT) of Telehealth-supported care within a community-based COPD supported-discharge service. METHODS A two-arm pragmatic pilot RCT was conducted comparing the standard service with a Telehealth-supported service and assessed the potential for progressing into a full RCT. The co-primary outcome measures were the proportion of COPD patients readmitted to hospital and changes in patients' self-reported quality of life. The objectives were to assess the suitability of the methodology, produce a sample size calculation for a full RCT, and to give an indication of cost-effectiveness for both pathways. RESULTS Sixty three participants were recruited (n = 31 Standard; n = 32 Telehealth); 15 participants were excluded from analysis due to inadequate data completion or withdrawal from the Telehealth arm. Recruitment was slow with significant gaps in data collection, due predominantly to an unanticipated 60% reduction of staff capacity within the clinical team. The sample size calculation was guided by estimates of clinically important effects and COPD readmission rates derived from the literature. Descriptive analyses showed that the standard service group had a lower proportion of patients with hospital readmissions and a greater increase in self-reported quality of life compared to the Telehealth-supported group. Telehealth was cost-effective only if hospital admissions data were excluded. CONCLUSIONS Slow recruitment rates and service reconfigurations prevented progression to a full RCT. Although there are advantages to conducting an RCT with data collection conducted by a frontline clinical team, in this case, challenges arose when resources within the team were reduced by external events. Gaps in data collection were resolved by recruiting a research nurse. This study reinforces previous findings regarding the difficulty of undertaking evaluation of complex interventions, and provides recommendations for the introduction and evaluation of complex interventions within clinical settings, such as prioritisation of research within the clinical remit.

Abstract
The soluble cleaved urokinase plasminogen activator receptor (scuPAR) is a circulating protein detected in multiple diseases, including various cancers, cardiovascular disease, and kidney disease, where elevated levels of scuPAR have been associated with worsening prognosis and increased disease aggressiveness. We aimed to identify novel genetic and biomolecular mechanisms regulating scuPAR levels. Elevated serum scuPAR levels were identified in asthma (n=514) and chronic obstructive pulmonary disease (COPD; n=219) cohorts when compared to controls (n=96). In these cohorts, a genome-wide association study of serum scuPAR levels identified a human plasma kallikrein gene (KLKB1) promoter polymorphism (rs4253238) associated with serum scuPAR levels in a control/asthma population (P=1.17×10−7), which was also observed in a COPD population (combined P=5.04×10−12). Using a fluorescent assay, we demonstrated that serum KLKB1 enzymatic activity was driven by rs4253238 and is inverse to scuPAR levels. Biochemical analysis identified that KLKB1 cleaves scuPAR and negates scuPAR's effects on primary human bronchial epithelial cells (HBECs) in vitro. Chymotrypsin was used as a proproteolytic control, while basal HBECs were used as a control to define scuPAR-driven effects. In summary, we reveal a novel post-translational regulatory mechanism for scuPAR using a hypothesis-free approach with implications for multiple human diseases.—Portelli, M. A., Siedlinski, M., Stewart, C. E., Postma, D. S., Nieuwenhuis, M. A., Vonk, J. M., Nurnberg, P., Altmuller, J., Moffatt, M. F., Wardlaw, A. J., Parker, S. G., Connolly, M. J., Koppelman, G.

Abstract
INTRODUCTION Bladder cancer is a significant epidemiological disease. It is managed by primary resection and on-going surveillance for recurrent disease. Intravesical BCG therapy is used in superficial carcinomas to lower the incidence of recurrence and prolong the time to recurrence. BCG therapy is not without its rare but serious side effects. PRESENTATION OF CASE A 75-year-old man presented to the urologist with right testicular pain, after four previous TURBT operations, two courses of intravesical BCG therapy and one STAT dose of intravesical mitomycin. The patient's USS testis showed hypoechoic lesions in the right testis. An orchiectomy was carried out due to the possibility of the USS showing a malignancy. Histology confirmed BCG epididymo-orchitis. DISCUSSION This patient presented with testicular pain fifteen months after the cessation of BCG therapy. Clinicians need to be aware of the potentially long dormancy periods for BCG infections, and their complications, as well as the acute infective BCG presentations. The literature is reviewed and shows the wide range of infective BCG presentations from acute disseminated sepsis to insidious focal infections such as parotiditis and discitis. CONCLUSION This case report demonstrates that due to the delayed and gradual onset of symptoms, BCG infections are difficult to diagnose. The report and the review remind surgeons to keep BCG infection amongst their differentials when treating patients who present after BCG therapy.

Abstract
OBJECTIVES To assess patient preferences for different models of care defined by location of care, frequency of care and principal carer within community-based health-care services for older people. DESIGN Discrete choice experiment administered within a face-to-face interview. SETTING An intermediate care service in a large city within the United Kingdom. PARTICIPANTS The projected sample size was calculated to be 200; however, 77 patients were recruited to the study. The subjects had recently been discharged from hospital and were living at home and were receiving short-term care by a publicly funded intermediate care service. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE The degree of preference, measured using single utility score, for individual service characteristics presented within a series of potential care packages. RESULTS Location of care was the dominant service characteristics with care at home being the strongly stated preference when compared with outpatient care (0.003), hospital care (<0.001) and nursing home care (<0.001) relative to home care, although this was less pronounced among less sick patients. Additionally, the respondents indicated a dislike for very frequent care contacts. No particular type of professional carer background was universally preferred but, unsurprisingly, there was evidence that sick patients showed a preference for nurse-led care. CONCLUSIONS Patients have clear preferences for the location for their care and were able to state preferences between different care packages when their ideal service was not available. Service providers can use this information to assess which models of care are most preferred within resource constraints.

Abstract
BACKGROUND Household devices may have a positive impact on daily lives by reducing the burden of several tasks and enriching social interaction. There are varieties of assistive devices such as alarms, sensors, detectors, and life style monitoring devices, which can help in compensating for the activity limitations caused by impairments. This study aimed to review the contribution that residential technology devices can make to older people's lives. METHODS An open-ended literature review following the guidance of the Centre for Review and Dissemination was conducted to establish the current understanding of the topics by using clear and appropriate criteria to select or reject studies. The studies entered into the review were limited by language, topic, and date of publication. RESULTS The research literature indicated that residential facilities which appropriately are designed and supplied can have many benefits for older people such as increasing in-dependence, maximising physical and mental health, and improving their quality of life. CONCLUSION Although most of the literature has explored the positive effects of technology devices on older adults' social networks, independence, psychological well-being, and social status, the possibilities of negative consequences have been neglected.

Abstract
Technological interventions could help older people live independently. In this study with 160 people aged 55 and over who were living in extra care housing in England we aimed to explore awareness of, access to, attitudes towards availability, and use of home-based technological (HBT)
devices, and factors that influence the use of devices. A quantitatively designed and structured questionnaire was developed for this study. The majority of new HBT devices were not available in living units or schemes. Moreover, most basic appliances and emergency call systems were used in
the living units. We found that in order to increase the use of technological devices among the elderly, their perceptions, capabilities, attitudes, and needs should be assessed in the designing, planning, and supplying process.

Abstract
Background We have previously shown evidence that polymorphisms within genes controlling leukotriene B4 (LTB4) production (ALOX5AP and LTA4H) are associated with asthma susceptibility in children. Evidence also suggests a potential role of LTB4 in COPD disease mechanisms including recruitment of neutrophils to the lung. The aim of the current study was to see if these SNPs and those spanning the receptor genes for LTB4 (LTB4R1 and LTB4R2) influence baseline lung function and COPD susceptibility/severity in smokers. Methods Eight ALOX5AP, six LTA4H and six LTB4R single nucleotide polymorphisms (SNPs) were genotyped in a UK Smoking Cohort (n = 992). Association with baseline lung function (FEV1 and FEV1/FVC ratio) was determined by linear regression. Logistic regression was used to compare smoking controls (n = 176) with spirometry-defined COPD cases (n = 599) and to more severe COPD cases (GOLD stage 3 and 4, n = 389). Results No association with ALOX5AP, LTA4H or LTB4R survived correction for multiple testing. However, we showed modest association with LTA4H rs1978331C (intron 11) with increased FEV1 (p = 0.029) and with increased FEV1/FVC ratio (p = 0.020). Conclusions These data suggest that polymorphisms spanning ALOX5AP, LTA4H and the LTB4R locus are not major determinants of baseline lung function in smokers, but provide tentative evidence for LTA4H rs1978331C (intron 11) in determining baseline FEV1 and FEV1/FVC ratio in Caucasian Smokers in addition to our previously identified role in asthma susceptibility.

Abstract
Background British government policy for older people focuses on a vision of active ageing and independent living. In the face of diminishing personal capacities, the use of appropriate home-based technology (HBT) devices could potentially meet a wide range of needs and consequently improve many aspects of older people's quality of life such as physical health, psychosocial well-being, social relationships, and their physical or living environment. This study aimed to examine the use of HBT devices and the correlation between use of such devices and quality of life among older people living in extra-care housing (ECH). Methods A structured questionnaire was administered for this study. Using purposive sampling 160 older people living in extra-care housing schemes were selected from 23 schemes in England. A face-to-face interview was conducted in each participant's living unit. In order to measure quality of life, the SEIQoL-Adapted and CASP-19 were used. Results Although most basic appliances and emergency call systems were used in the living units, communally provided facilities such as personal computers, washing machines, and assisted bathing equipment in the schemes were not well utilised. Multiple regression analysis adjusted for confounders including age, sex, marital status, living arrangement and mobility use indicated a coefficient of 1.17 with 95% CI (0.05, 2.29) and p = 0.04 [SEIQoL-Adapted] and 2.83 with 95% CI (1.17, 4.50) and p = 0.001 [CASP-19]. Conclusions The findings of the present study will be value to those who are developing new form of specialised housing for older people with functional limitations and, in particular, guiding investments in technological aids. The results of the present study also indicate that the home is an essential site for developing residential technologies.

Abstract
OBJECTIVES to test the hypothesis that older people and their informal carers are not disadvantaged by home-based rehabilitation (HBR) relative to day hospital rehabilitation (DHR). DESIGN pragmatic randomised controlled trial. SETTING four geriatric day hospitals and four home rehabilitation teams in England. PARTICIPANTS eighty-nine patients referred for multidisciplinary rehabilitation. The target sample size was 460. INTERVENTION multidisciplinary rehabilitation either in the home or in the day hospital. MEASUREMENTS the primary outcome measure was the Nottingham extended activities of daily living scale (NEADL). Secondary outcome measures included EQ-5D, hospital anxiety and depression scale, therapy outcome measures, hospital admissions and the General Health Questionnaire for carers. RESULTS at the primary end point of 6 months NEADL scores were not significantly in favour of HBR cf. DHR; mean difference -2.139 (95% confidence interval -6.87 to 2.59, P = 0.37). A post hoc analysis suggested non-inferiority for HBR for NEADL but there was considerable statistical uncertainty. CONCLUSION taken together the statistical analyses and lack of power of the trial outcomes do not provide sufficient evidence to conclude that patients in receipt of HBR are disadvantaged compared with those receiving DHR.

Abstract
BACKGROUND many frail older people who attend acute hospital settings and who are discharged home within short periods (up to 72 h) have poor outcomes. This review assessed the role of comprehensive geriatric assessment (CGA) for such people. METHODS standard bibliographic databases were searched for high-quality randomised controlled trials (RCTs) of CGA in this setting. When appropriate, intervention effects were presented as rate ratios with 95% confidence intervals. RESULTS five trials of sufficient quality were included. There was no clear evidence of benefit for CGA interventions in this population in terms of mortality [RR 0.92 (95% CI 0.55-1.52)] or readmissions [RR 0.95 (95% CI 0.83-1.08)] or for subsequent institutionalisation, functional ability, quality-of-life or cognition. CONCLUSIONS there is no clear evidence of benefit for CGA interventions in frail older people being discharged from emergency departments or acute medical units. However, few such trials have been carried out and their overall quality was poor. Further well designed trials are justified.

Abstract
BACKGROUND Asthma and chronic obstructive pulmonary disease (COPD) are chronic respiratory diseases involving an interaction between genetic and environmental factors. Interleukin-13 (IL13) has been suggested to have a role in both asthma and COPD. We investigated whether single nucleotide polymorphisms (SNPs) in the IL13 pathway may contribute to the susceptibility and severity of asthma and COPD in adults. METHODS Twelve SNPs in IL13 pathway genes -IL4, IL13, IL4RA, IL13RA1, IL13RA2 and STAT6- were genotyped in subjects with asthma (n = 299) and in subjects with COPD or healthy smokers (n = 992). Genetic association was evaluated using genotype and allele models for asthma severity, atopy phenotypes and COPD susceptibility. Linear regression was used to determine the effects of polymorphism on baseline lung function (FEV(1), FEV(1)/FVC). RESULTS In asthmatics, three IL13 SNPs - rs1881457(-1512), rs1800925(-1111) and rs20541(R130Q) - were associated with atopy risk. One SNP in IL4RA1 [rs1805010(I75V)] was associated with asthma severity, and several IL13 SNPs showed borderline significance. IL13 SNPs rs1881457(-1512) and rs1800925(-1111) were associated with better FEV(1) and FEV(1)/FVC in asthmatics. IL13 SNPs rs2066960(intron 1), rs20541(R130Q) and rs1295685(exon 4) were associated with COPD risk and lower baseline lung function in the recessive model. In females, but not in males, rs2250747 of the IL13RA1 gene was associated with COPD and lower FEV(1). CONCLUSION These data suggest that IL13 SNPs (promoter and coding region) and, to a lesser extent, IL4RA SNPs may contribute to atopy and asthma. We also provide tentative evidence that IL13 SNPs in the coding region may be of significance in COPD susceptibility.

Abstract
Background The success of a human intervention trial depends upon the ability to recruit eligible volunteers. Many trials fail because of unrealistic recruitment targets and flawed recruitment strategies. In order to predict recruitment rates accurately, researchers need information on the relative success of various recruitment strategies. Few published trials include such information and the number of participants screened or approached is not always cited. Methods This paper will describe in detail the recruitment strategies employed to identify older adults for recruitment to a 6-month randomised controlled dietary intervention trial which aimed to explore the relationship between diet and immune function (The FIT study). The number of people approached and recruited, and the reasons for exclusion, will be discussed. Results Two hundred and seventeen participants were recruited to the trial. A total of 7,482 letters were sent to potential recruits using names and addresses that had been supplied by local Family (General) Practices. Eight hundred and forty three potential recruits replied to all methods of recruitment (528 from GP letters and 315 from other methods). The eligibility of those who replied was determined using a screening telephone interview, 217 of whom were found to be suitable and agreed to take part in the study. Conclusion The study demonstrates the application of multiple recruitment methods to successfully recruit older people to a randomised controlled trial. The most successful recruitment method was by contacting potential recruits by letter on NHS headed note paper using contacts provided from General Practices. Ninety percent of recruitment was achieved using this method. Adequate recruitment is fundamental to the success of a research project, and appropriate strategies must therefore be adopted in order to identify eligible individuals and achieve recruitment targets. Trial registration number ISRCTN45031464.

Abstract
OBJECTIVES To test the hypotheses that older people and their informal carers are not disadvantaged by home-based rehabilitation (HBR) relative to day hospital rehabilitation (DHR) and that HBR is less costly. DESIGN Two-arm randomised controlled trial. SETTING Four trusts in England providing both HBR and DHR. PARTICIPANTS Clinical staff reviewed consecutive referrals to identify subjects who were potentially suitable for randomisation according to the defined inclusion criteria. INTERVENTIONS Patients were randomised to receive either HBR or DHR. MAIN OUTCOME MEASURES The primary outcome measure was the Nottingham Extended Activities of Daily Living (NEADL) scale. Secondary outcome measures included the EuroQol 5 dimensions (EQ-5D), Hospital Anxiety and Depression Scale (HADS), Therapy Outcome Measures (TOMs), hospital admissions and the General Health Questionnaire (GHQ-30) for carers. RESULTS Overall, 89 subjects were randomised and 42 received rehabilitation in each arm of the trial. At the primary end point of 6 months there were 32 and 33 patients in the HBR and DHR arms respectively. Estimated mean scores on the NEADL scale at 6 months, after adjustment for baseline, were not significantly in favour of either HBR or DHR [DHR 30.78 (SD 15.01), HBR 32.11 (SD 16.89), p = 0.37; mean difference -2.139 (95% CI -6.870 to 2.592)]. Analysis of the non-inferiority of HBR over DHR using a 'non-inferiority' limit (10%) applied to the confidence interval estimates for the different outcome measures at 6 months' follow-up demonstrated non-inferiority for the NEADL scale, EQ-5D and HADS anxiety scale and some advantage for HBR on the HADS depression scale, of borderline statistical significance. Similar results were seen at 3 and 12 months' follow-up, with a statistically significant difference in the mean EQ-5D(index) score in favour of DHR at 3 months (p = 0.047). At the end of rehabilitation, a greater proportion of the DHR group showed a positive direction of change from their initial assessment with respect to therapist-rated clinical outcomes; however, a lower proportion of HBR patients showed a negative direction of change and, overall, median scores on the TOMs scales did not differ between the two groups. Fewer patients in the HBR group were admitted to hospital on any occasion over the 12-month observation period [18 (43%) versus 22 (52%)]; however, this difference was not statistically significant. The psychological well-being of patients' carers, measured at 3, 6 and 12 months, was unaffected by whether rehabilitation took place at day hospital or at home. As the primary outcome measure and EQ-5D(index) scores at 6 months showed no significant differences between the two arms of the trial, a cost-minimisation analysis was undertaken. Neither the public costs nor the total costs at the 6-month follow-up point (an average of 213 days' total follow-up) or the 12-month follow-up point (an average of 395 days' total follow-up) were significantly different between the groups. CONCLUSIONS Compared with DHR, providing rehabilitation in patients' own homes confers no particular disadvantage for patients and carers. The cost of providing HBR does not appear to be significantly different from that of providing DHR. Rehabilitation providers and purchasers need to consider the place of care in the light of local needs, to provide the benefits of both kinds of services. Caution is required when interpreting the results of the RCT because a large proportion of potentially eligible subjects were not recruited to the trial, the required sample size was not achieved and there was a relatively large loss to follow-up.

Abstract
Background We have previously identified Urokinase Plasminogen Activator Receptor (PLAUR) as an asthma susceptibility gene. In the current study we tested the hypothesis that PLAUR single nucleotide polymorphisms (SNPs) determine baseline lung function and contribute to the development of Chronic Obstructive Pulmonary Disease (COPD) in smokers. Methods 25 PLAUR SNPs were genotyped in COPD subjects and individuals with smoking history (n = 992). Linear regression was used to determine the effects of polymorphism on baseline lung function (FEV1, FEV1/FVC) in all smokers. Genotype frequencies were compared in spirometry defined smoking controls (n = 176) versus COPD cases (n = 599) and COPD severity (GOLD stratification) using logistic regression. Results Five SNPs showed a significant association (p < 0.01) with baseline lung function; rs2302524(Lys220Arg) and rs2283628(intron 3) were associated with lower and higher FEV1 respectively. rs740587(-22346), rs11668247(-20040) and rs344779(-3666) in the 5'region were associated with increased FEV1/FVC ratio. rs740587 was also protective for COPD susceptibility and rs11668247 was protective for COPD severity although no allele dose relationship was apparent. Interestingly, several of these associations were driven by male smokers not females. Conclusion This study provides tentative evidence that the asthma associated gene PLAUR also influences baseline lung function in smokers. However the case-control analyses do not support the conclusion that PLAUR is a major COPD susceptibility gene in smokers. PLAUR is a key serine protease receptor involved in the generation of plasmin and has been implicated in airway remodelling.

Abstract
The purpose of this paper was to develop a pro forma which classifies the components of service delivery and organization which may impact on the outcomes of elderly peoples' community and intermediate care services. The resulting analytic template provides a basis for comparison between services and may help guide service commissioning and development. A qualitative approach was used in which key evaluations and reports were selected on the basis that they described elderly peoples' community and intermediate care services. These were analysed systematically using a qualitative (template) approach to draw out the key themes used to describe services. Themes were then structured hierarchically into an analytic template. Seventeen key documents were analysed. The initial coding framework classified 334 themes describing intermediate care services. These items were then clustered into 78 categories, which were reduced to 17 subcategories, then six overall groupings to describe the services, namely; (1) context; (2) reason for the service; (3) service-users; (4) access to the service; (5) service structure; and (6) the organization of care. The resulting analytic template has been developed into a 'service pro forma' which can be used as a basis to describe and compare a range of services. We propose that all service evaluations should describe, in detail, their context in a comparable way, so that other services can learn from and/or apply the findings from these studies.

Abstract
BACKGROUND The effectiveness of community-based geriatric intervention models for vulnerable older adults is controversial. We evaluated a problem-based multidisciplinary intervention targeting vulnerable older adults at home that promised efficacy through better timing and increased commitment of patients and primary care physicians. This study compared the effects of this new model to usual care. METHODS Primary care physicians referred older people for problems with cognition, nutrition, behavior, mood, or mobility. One hundred fifty-one participants (mean age 82.2 years, 74.8% women) were included in a pseudocluster randomized trial with 6-month follow-up for the primary outcomes. Eighty-five participants received the new intervention, and 66 usual care. In the intervention arm, geriatric nurses visited patients at home for geriatric assessment and management in cooperation with primary care physicians and geriatricians. Modified intention-to-treat analyses focused on differences between treatment arms in functional abilities (Groningen Activity Restriction Scale-3) and mental well-being (subscale mental health Medical Outcomes Study [MOS]-20), using a mixed linear model. RESULTS After 3 months, treatment arms showed significant differences in favor of the new intervention. Functional abilities improved 2.2 points (95% confidence interval [CI], 0.3-4.2) and well-being 5.8 points (95% CI, 0.1-11.4). After 6 months, the favorable effect increased for well-being (9.1; 95% CI, 2.4-15.9), but the effect on functional abilities was no longer significant (1.6; 95% CI, -0.7 to 3.9). CONCLUSIONS This problem-based geriatric intervention improved functional abilities and mental well-being of vulnerable older people. Problem-based interventions can increase the effectiveness of primary care for this population.

Abstract
We aimed to examine the role of tumour necrosis factor gene complex polymorphisms in subjects with chronic obstructive pulmonary disease (COPD). We hypothesized that individuals possessing polymorphic variants associated with higher tumour necrosis factor (TNF) secretion would be more susceptible to and/or have more severe disease. Patients with COPD and population controls underwent detailed clinical phenotyping. Genotyping for the tumour necrosis factor-308 and the lymphotoxin alpha NcoI (LTalpha polymorphisms was carried out by 'blinded' laboratory staff. Three hundred and sixty one individuals (220 cases and 141 controls) were recruited. We showed an association between the LTalphaNcol polymorphism and forced vital capacity (FVC) in a population of older adults with and without COPD. The LTalphaNcol*2 allele was associated with poorer lung function, under a codominant model, with a fall in FVC (expressed as a percentage of its predicted value) of 3.7% for each copy of the LTalphaNcol*2 allele possessed (for FVC, regression coefficient (95% CI)=-3.73(-7.01 to -0.44), P=0.026; for FEV(1) regression coefficient=-3.56(-7.80 to 0.70), P=0.101. However, there was no difference in genotype distribution between the case and control populations. This study adds weight to the suggestion that the TNF gene complex is involved in physiological alterations (FVC) that may affect the development and severity of COPD. The absence of a significant association between the TNF gene-complex polymorphisms in this study does not rule out a modest effect of these polymorphisms on the risk of COPD, as much larger studies are needed to detect modest gene effects on binary disease endpoints.

SETTING/PARTICIPANTS An SF-36 was administered to 245 subjects aged 65 years and older. Subjects were chosen by sampling from a variety of inpatient, outpatient and community sources to ensure a range of relevant disabilities. MEASUREMENTS response rates, overall rates of completion, completion of individual questions and time taken to complete. RESULTS severe functional impairment (Barthel index < or = 12) was found in 22.4% (51/228), cognitive impairment in 54.1% (132/244), depressed mood in 77.0% (151/196) and visuospatial dysfunction in 71.3% (134/188). The median number of impairments was three (interquartile range 1-4). Specific physical impairments were visual in 13.2% (31/235), hearing in 30.2% (74/245), impaired manual dexterity in 18.0% (44/245) and dysphasia in 23% (55/239). In multivariate analyses, global functional impairment (P = 0.006), cognitive impairment (P = 0.0001) and impaired manual dexterity (P = 0.005) were significantly associated with more dimensions uncompleted, whilst cognitive impairment (P = 0.001), age (P = 0.006) and visuospatial dysfunction (P = 0.0003) were significantly associated with longer completion times. CONCLUSION the most striking finding of the study was that global rather than specific physical and mental dysfunction was associated with the inability to complete the SF-36 questionnaire. The difficulty appears to lie in the performance of a complex task, rather than with specific aspects of the task which could be overcome by adaptation or aids. Our experience is that this relatively complex questionnaire does not adequately measure functional health status in disabled older people because of non-completion and may therefore overestimate the health of populations.

Abstract
BACKGROUND Increasingly, molecular genetic techniques are being used to improve our understanding of a number of common late onset complex disorders, such as hypertension, Alzheimer's disease and noninsulin dependent diabetes mellitus. Molecular genetic approaches have the potential to yield new information about disease pathogenesis that may be of great importance for the development of future treatments. AIMS This review discusses the evidence for a genetic contribution to the development of chronic obstructive pulmonary disease (COPD) and specifically focuses on the hypothesis that asthma and COPD share some pathogenic mechanisms as originally proposed in 1960 in a theory that has since become known as the Dutch Hypothesis. In particular we will review the evidence from molecular genetics, both in support of and against the theory.
