The objective of the current study was to evaluate the effect of a debriefing call on nutrient intake estimates using two 3-d food diaries among women participating in the Women's Health and Interview Study (WISH) Diet Validation Study. Subjects were 207 women with complete data and six 24-h recalls (24-HR) by telephone over 8 mo followed by two 3-d food diaries during the next 4 mo. Nutrient intake was assessed using the food diaries before and after a debriefing session by telephone. The purpose of the debriefing call was to obtain more detailed information on the types and amounts of fat in the diet. However, due to the ubiquitous nature of fat in the diet, the debriefing involved providing more specific detail on many aspects of the diet. There was a significant difference in macronutrient and micronutrient intake estimates after the debriefing. Estimates of protein, carbohydrate, and fiber intake were significantly higher and total fat, monounsaturated fat, saturated fat, vitamin A, vitamin C, -tocopherol, folic acid, and calcium intake were significantly lower after the debriefing (P <0.05). The limits of agreement between the food diaries before and after the debriefing were especially large for total fat intake, which could be under- or overestimated by 15 g/d. The debriefing call improved attenuation coefficients associated with measurement error for vitamin C, folic acid, iron, tocopherol, vitamin A, and calcium estimates. A hypothetical relative risk (RR) = 2.0 could be attenuated to 1.16 for folic acid intake assessed without a debriefing but to only 1.61 with a debriefing. Depending on the nutrients of interest, the inclusion of a debriefing can reduce the potential attenuation of RR in studies evaluating diet disease associations.

Low intakes of fruit and vegetables have previously been reported in the older population of Great Britain, particularly among certain socio-demographic groups. Levels and patterns of consumption in the older population of Northern Ireland, however, remain unknown. A representative sample of 1000 members of the older population of Northern Ireland were contacted by telephone to assess average intake of all fruits and vegetables and various demographic details. Data from 426 individuals (representative of the whole population) reported a mean consumption of 4.0 (SD 1-3) and 4.1 (SD 1-3) portions of fruit and vegetables per weekday and per weekend day respectively. Regression analyses revealed greater consumption on weekdays by females (B 0.53; P

Objective: Interventions to reduce health inequalities for young children and their mothers are important: involving peers is recommended, but evidence of value for this approach is limited. The authors aimed to examine the effect of an innovative tailored peer-mentoring programme, based on perceived needs, for first-time mothers in socio-economically deprived communities. Design: Randomised controlled trial; parallel qualitative study with purposive samples using semistructured interviews. Setting: Socio-economically disadvantaged areas, Belfast. Participants: Primigravidae, aged 16-30 years, without significant co-morbidity. Intervention: Peer-mentoring by a lay-worker fortnightly during pregnancy and monthly for the following year, tailored to participants' wishes (home visits/telephone contacts), additional to usual care. Main outcome measures: Infant psychomotor and mental development (Bayley Scales of Infant Development (BSID-II)) at 1 year, assessed by an observer blinded to group allocation. Mothers' health at 1 year postnatal (SF-36). Results: Of 534 women invited, 343(64%) participated; 85%, with their children, completed outcome assessments (140 of 172 intervention; 152 of 171 controls). Intervention and control groups did not differ in BSID-II psychomotor (mean difference 1.64, 95% CI -0.94 to 4.21) or mental (-0.81, -2.78 to 1.16) scores, nor SF-36 physical functioning (-5.4, -11.6 to 0.7) or mental health (-1.8, -6.1 to 2.6). Women valued advice given in context of personal experience of child-rearing. Mentors gained health-related knowledge, personal skills and new employment opportunities. Conclusions: Despite possible longer-term social advantage, this peer-mentoring programme showed no benefit for infant development or maternal health at 1 year. Further rigorous evaluation of important outcomes of complex interventions promoting health for children in socially disadvantaged communities is warranted. Trial registration no: ISRCTN 55055030.

The management and delivery of bereavement support services in palliative care settings presents practical and ethical challenges. A national survey, conducted in 2007, examined bereavement practice in ten Marie Curie hospices across the United Kingdom. This qualitative study was undertaken using semi-structured telephone interviews with Bereavement Service Leaders located in each hospice. Although findings revealed that bereavement services were in operation and had been reviewed in response to the National Institute for Clinical Excellence Guidance (2004), and all bereaved families were offered support, there was no standardisation of service delivery across sites. Multi-disciplinary team meetings facilitated shared decision-making for bereavement follow-up, and expanded and clarified documentation completed by nursing staff around the time of the patient’s death. However, there was ambiguity regarding professional ‘duty of care’ and agency responses to bereaved individuals who were suicidal. Questions were raised around clinical effectiveness, reliability and professional accountability. The study highlighted ethical issues centred on documentation, user participation and consent, and found staff training was variable across the 10 hospices. The findings have informed the development of a post-bereavement service model which has been subsequently implemented across Marie Curie Cancer Care.

Marie Curie Cancer Care (MCCC) is a national charitable organisation which provides specialist palliative care services to patients with cancer and other life limiting illnesses. Marie Curie Nursing Service (MCNS) provides nursing services to patients in their own homes. The administration of blood transfusions to palliative care patients is required to improve symptom management and quality of life; however this procedure often results in unnecessary hospital admissions. Recognising that the majority of patients wish to be cared for and die in their own home, and with National Guidance recommending that specialist palliative care services should be provided to patients in their preferred place of care, a recent service initiative by MCNS was domiciliary blood transfusions. Whilst this is not a new service within domiciliary care, this pilot project aimed to capture patient views to evaluate this service initiative. Telephone interviews were conducted, using a questionnaire, with 11 patients who had received the service. Findings indicated positive evaluation of the service. Domiciliary blood transfusions helped to avoid unnecessary hospital admissions, the quality of life of patients and their families was improved in the palliative phase of illness and they received the service in their preferred place of care.

Background: In the Medical Research Council (MRC) COIN trial, the epidermal growth factor receptor (EGFR)-targeted antibody cetuximab was added to standard chemotherapy in first-line treatment of advanced colorectal cancer with the aim of assessing effect on overall survival.
Methods: In this randomised controlled trial, patients who were fit for but had not received previous chemotherapy for advanced colorectal cancer were randomly assigned to oxaliplatin and fluoropyrimidine chemotherapy (arm A), the same combination plus cetuximab (arm B), or intermittent chemotherapy (arm C). The choice of fluoropyrimidine therapy (capecitabine or infused fluouroracil plus leucovorin) was decided before randomisation. Randomisation was done centrally (via telephone) by the MRC Clinical Trials Unit using minimisation. Treatment allocation was not masked. The comparison of arms A and C is described in a companion paper. Here, we present the comparison of arm A and B, for which the primary outcome was overall survival in patients with KRAS wild-type tumours. Analysis was by intention to treat. Further analyses with respect to NRAS, BRAF, and EGFR status were done. The trial is registered, ISRCTN27286448.
Findings: 1630 patients were randomly assigned to treatment groups (815 to standard therapy and 815 to addition of cetuximab). Tumour samples from 1316 (81%) patients were used for somatic molecular analyses; 565 (43%) had KRAS mutations. In patients with KRAS wild-type tumours (arm A, n=367; arm B, n=362), overall survival did not differ between treatment groups (median survival 17·9 months [IQR 10·3—29·2] in the control group vs 17·0 months [9·4—30·1] in the cetuximab group; HR 1·04, 95% CI 0·87—1·23, p=0·67). Similarly, there was no effect on progression-free survival (8·6 months [IQR 5·0—12·5] in the control group vs 8·6 months [5·1—13·8] in the cetuximab group; HR 0·96, 0·82—1·12, p=0·60). Overall response rate increased from 57% (n=209) with chemotherapy alone to 64% (n=232) with addition of cetuximab (p=0·049). Grade 3 and higher skin and gastrointestinal toxic effects were increased with cetuximab (14 vs 114 and 67 vs 97 patients in the control group vs the cetuximab group with KRAS wild-type tumours, respectively). Overall survival differs by somatic mutation status irrespective of treatment received: BRAF mutant, 8·8 months (IQR 4·5—27·4); KRAS mutant, 14·4 months (8·5—24·0); all wild-type, 20·1 months (11·5—31·7).
Interpretation: This trial has not confirmed a benefit of addition of cetuximab to oxaliplatin-based chemotherapy in first-line treatment of patients with advanced colorectal cancer. Cetuximab increases response rate, with no evidence of benefit in progression-free or overall survival in KRAS wild-type patients or even in patients selected by additional mutational analysis of their tumours. The use of cetuximab in combination with oxaliplatin and capecitabine in first-line chemotherapy in patients with widespread metastases cannot be recommended.

Background: When cure is impossible, cancer treatment should focus on both length and quality of life. Maximisation of time without toxic effects could be one effective strategy to achieve both of these goals. The COIN trial assessed preplanned treatment holidays in advanced colorectal cancer to achieve this aim. Methods: COIN was a randomised controlled trial in patients with previously untreated advanced colorectal cancer. Patients received either continuous oxaliplatin and fluoropyrimidine combination (arm A), continuous chemotherapy plus cetuximab (arm B), or intermittent (arm C) chemotherapy. In arms A and B, treatment continued until development of progressive disease, cumulative toxic effects, or the patient chose to stop. In arm C, patients who had not progressed at their 12-week scan started a chemotherapy-free interval until evidence of disease progression, when the same treatment was restarted. Randomisation was done centrally (via telephone) by the MRC Clinical Trials Unit using minimisation. Treatment allocation was not masked. The comparison of arms A and B is described in a companion paper. Here, we compare arms A and C, with the primary objective of establishing whether overall survival on intermittent therapy was non-inferior to that on continuous therapy, with a predefined non-inferiority boundary of 1·162. Intention-to-treat (ITT) and per-protocol analyses were done. This trial is registered, ISRCTN27286448. Findings: 1630 patients were randomly assigned to treatment groups (815 to continuous and 815 to intermittent therapy). Median survival in the ITT population (n=815 in both groups) was 15·8 months (IQR 9·4—26·1) in arm A and 14·4 months (8·0—24·7) in arm C (hazard ratio [HR] 1·084, 80% CI 1·008—1·165). In the per-protocol population (arm A, n=467; arm C, n=511), median survival was 19·6 months (13·0—28·1) in arm A and 18·0 months (12·1—29·3) in arm C (HR 1·087, 0·986—1·198). The upper limits of CIs for HRs in both analyses were greater than the predefined non-inferiority boundary. Preplanned subgroup analyses in the per-protocol population showed that a raised baseline platelet count, defined as 400 000 per µL or higher (271 [28%] of 978 patients), was associated with poor survival with intermittent chemotherapy: the HR for comparison of arm C and arm A in patients with a normal platelet count was 0·96 (95% CI 0·80—1·15, p=0·66), versus 1·54 (1·17—2·03, p=0·0018) in patients with a raised platelet count (p=0·0027 for interaction). In the per-protocol population, more patients on continuous than on intermittent treatment had grade 3 or worse haematological toxic effects (72 [15%] vs 60 [12%]), whereas nausea and vomiting were more common on intermittent treatment (11 [2%] vs 43 [8%]). Grade 3 or worse peripheral neuropathy (126 [27%] vs 25 [5%]) and hand—foot syndrome (21 [4%] vs 15 [3%]) were more frequent on continuous than on intermittent treatment. Interpretation: Although this trial did not show non-inferiority of intermittent compared with continuous chemotherapy for advanced colorectal cancer in terms of overall survival, chemotherapy-free intervals remain a treatment option for some patients with advanced colorectal cancer, offering reduced time on chemotherapy, reduced cumulative toxic effects, and improved quality of life. Subgroup analyses suggest that patients with normal baseline platelet counts could gain the benefits of intermittent chemotherapy without detriment in survival, whereas those with raised baseline platelet counts have impaired survival and quality of life with intermittent chemotherapy and should not receive a treatment break.

Background: This is an update of a Cochrane review first published in 2001. At that stage there was insufficient evidence to recommend statins for the prevention of Alzheimer's disease (AD). The scope of this review has been expanded to include all forms of dementia.
Objectives: To assess the effects of statins in the prevention of dementia.
Search strategy: The Specialized Register of the Cochrane Dementia and Cognitive Improvement Group, The Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL and LILACS were searched on 10 October 2007 using the terms statin*, lovastatin*, pravastatin*, simvastatin*, fluvastatin*, atorvastatin* and rosuvastatin*. The CDCIG Register contains records from many healthcare databases, SIGLE, LILACS as well as many trials databases and is updated regularly.
Selection criteria: Double-blind randomized placebo-controlled trials of statins in people at risk of AD and dementia.
Data collection and analysis: Two independent reviewers extracted and assessed data independently and agreement was reached after discussion. Adverse effects were noted.
Main results: Two trials were identified with 26,340 participants; HPS 2002 and PROSPER 2002. Age range was 40-82 years across the two studies, PROSPER 2002 included 5804 patients aged 70-82 years and HPS included 20,536 patients with 5806 at least 70 years old at study entry. Mean total cholesterol 5.9 mmol/l, LDL cholesterol 3.4 mmol/l at study entry with mean reduction in LDL cholesterol of 1.0mmol/l in simvastatin treated patients compared to placebo in HPS 2002. Mean total cholesterol 5.7 mmol/l, LDL cholesterol 3.8 mmol/l at study entry with mean reduction in LDL cholesterol of 1.02 mmol/l in pravastatin treated patients compared to placebo in PROSPER 2002. Mean follow-up 3.2 years in PROSPER, 5 years in HPS 2002. Cognition was measured at different times and with different scales so could not be combined in a meta-analysis. There was no difference in incidence of dementia in HPS 2002 (31 cases in simvastatin group, 31 cases in placebo group) nor in performance on the modified Telephone Interview for Cognitive Status at final follow-up (23.7% simvastatin group cognitively impaired vs 24.2% in placebo group). There was no difference in cognition between groups either in relation to age at study entry or previous history of cerebrovascular disease. Cognitive function declined at the same rate in both treatment groups in PROSPER 2002, there was no significant difference between pravastatin treated and placebo groups in performance on letter digit codes, picture word learning test, Stroop and Mini Mental State Examination. There was no evidence that statins were detrimental to cognition.
Authors' conclusions : There is good evidence from RCTs that statins given in late life to individuals at risk of vascular disease have no effect in preventing AD or dementia. Biologically it seems feasible that statins could prevent dementia due to their role in cholesterol reduction and initial evidence from observational studies was very promising. Indication bias may have been a factor in these studies however and the evidence from subsequent RCTs has been negative.

Objectives: Research in residential homes has been limited to date and the extent of systemic and topical antimicrobial prescribing is largely unknown. The aim of this study was to investigate antimicrobial prescribing in residential homes in Northern Ireland (NI).
Methods: Point prevalence studies (PPSs) were completed in November 2010 (PPS1) and April 2011 (PPS2) in 30 residential homes. Data were obtained from care plans, medication administration records and staff in relation to antimicrobial prescribing and facility and resident characteristics, and analysed descriptively.
Results: The point prevalence of systemic antimicrobial prescribing was 9.4% in PPS1 and 9.2% in PPS2 (range 0.0%–33.3% during both PPSs). Trimethoprim was the most commonly prescribed systemic antimicrobial and the main indication was the prevention of urinary tract infections. Almost 25% of systemic antimicrobials were prescribed at inappropriate doses. The point prevalence of topical antimicrobial prescribing was 6.4% (range 0.0%–22.2%) in PPS1 and 5.9% (range 0.0%–21.1%) in PPS2. The most commonly prescribed topical antimicrobials were chloramphenicol eye preparations in PPS1 and fusidic acid skin preparations in PPS2; treatment with these topical antimicrobials was generally prolonged. More than 25% of all systemic and 55% of all topical antimicrobials were initiated following telephone consultations as opposed to face-to-face consultations.
Conclusions: The prevalence of systemic antimicrobial prescribing in residential homes in NI is relatively high compared with care homes (particularly nursing homes) in other countries. Systemic and topical antimicrobial prescribing is not always appropriate in terms of the doses prescribed and the duration of use. It is apparent that current strategies employed in NI are insuf?cient to ensure prudent antimicrobial prescribing within this environment.

BACKGROUND:
In a previous randomised controlled phase 2 trial, intravenous infusion of salbutamol for up to 7 days in patients with acute respiratory distress syndrome (ARDS) reduced extravascular lung water and plateau airway pressure. We assessed the effects of this intervention on mortality in patients with ARDS.
METHODS:
We did a multicentre, placebo-controlled, parallel-group, randomised trial at 46 UK intensive-care units between December, 2006, and March, 2010. Intubated and mechanically ventilated patients (aged =16 years) within 72 h of ARDS onset were randomly assigned to receive either salbutamol (15 µg/kg ideal bodyweight per h) or placebo for up to 7 days. Randomisation was done by a central telephone or web-based randomisation service with minmisation by centre, pressure of arterial oxygen to fractional inspired oxygen concentration (PaO(2)/F(I)O(2)) ratio, and age. All participants, caregivers, and investigators were masked to group allocation. The primary outcome was death within 28 days of randomisation. Analysis was by intention-to-treat. This trial is registered, ISRCTN38366450 and EudraCT number 2006-002647-86.
FINDINGS:
We randomly assigned 162 patients to the salbutamol group and 164 to the placebo group. One patient in each group withdrew consent. Recruitment was stopped after the second interim analysis because of safety concerns. Salbutamol increased 28-day mortality (55 [34%] of 161 patients died in the salbutamol group vs 38 (23%) of 163 in the placebo group; risk ratio [RR] 1·47, 95% CI 1·03-2·08).
INTERPRETATION:
Treatment with intravenous salbutamol early in the course of ARDS was poorly tolerated. Treatment is unlikely to be beneficial, and could worsen outcomes. Routine use of ß-2 agonist treatment in ventilated patients with this disorder cannot be recommended.

BACKGROUND: Low physical activity (PA) levels which increase the risk of chronic disease are reported by two-thirds of the general UK population. Promotion of PA by primary healthcare professionals is advocated but more evidence is needed regarding effective ways of integrating this within everyday practice. This study aims to explore the feasibility of a randomised trial of a pedometer-based intervention, using step-count goals, recruiting patients from primary care. METHOD: Patients, aged 35-75, attending four practices in socioeconomically deprived areas, were invited to complete a General Practice PA Questionnaire during routine consultations. Health professionals invited 'inactive' individuals to a pedometer-based intervention and were randomly allocated to group 1 (prescribed a self-determined goal) or group 2 (prescribed a specific goal of 2500 steps/day above baseline). Both groups kept step-count diaries and received telephone follow-up at 1, 2, 6 and 11 weeks. Step counts were reassessed after 12 weeks. RESULTS: Of the 2154 patients attending, 192 questionnaires were completed (8.9%). Of these, 83 were classified as 'inactive'; 41(10 men; 31 women) completed baseline assessments, with the mean age of participants being 51 years. Mean baseline step counts were similar in group 1 (5685, SD 2945) and group 2 (6513, SD 3350). The mean increase in steps/day was greater in groups 1 than 2 ((2602, SD 1957) vs (748, SD 1997) p=0.005). CONCLUSIONS: A trial of a pedometer-based intervention using self-determined step counts appears feasible in primary care. Pedometers appear acceptable to women, particularly at a perimenopausal age, when it is important to engage in impact loading activities such as walking to maintain bone mineral density. An increase of 2500 steps/day is achievable for inactive patients, but the effectiveness of different approaches to realistic goal-setting warrants further study.

Objective: The ability of families to assume caregiving responsibilities is contingent on material, social, and professional support. Inadequate or inappropriate support to the terminally ill and their family caregivers can result in the misuse of resources and add burden to the family. In this report, we describe service preferences among informal caregivers of the terminally ill. Design: Three hundred seventy-three caregivers participated in telephone interviews at two points in time: when the terminally ill person was designated as palliative and 5 months subsequent to the first interview. In the case that the care recipient died during the study period, the caregiver participated in the interview three months after the death. Measures: After reviewing possible services received by the care recipients and caregivers, caregivers were asked to identify the five services they found most valuable and which services they would have liked to have had or received more of when caregiving. Results: The five services caregivers reported as most valuable included: in-home nursing care, (90.7%); family physicians, (45.6%); medical specialists, (46.4%); housekeeping, (23.6%); and, religious support, (11.3%). The five most frequently reported services that family caregivers would have liked to have received or had more available included: housekeeping, (13.1%); caregiver respite, (10.2%); in-home nursing care, (8.0%); personal support workers, (4.6%); and, self-help/support groups, (3.8%). Analyses revealed that most (64.8%) perceived service needs were of a supportive nature for caregivers. Caregiver perceptions of the value and perceived need of services were consistent over time and into bereavement. Logistic regression analyses suggested that younger caregivers who were not employed, reported higher levels of burden and cared for someone with a diagnosis of cancer had greater perceived service needs. Conclusions: The findings reported in this paper provide important insights into caregiver perceptions of valued services when caring for a terminally ill family member. These finding also highlight the stability of caregiver service perceptions over time and into bereavement.

The purpose of this study was to examine gender differences in spousal caregiving at the end of life. The primary research question was to determine gender differences in caregiver strain among spousal caregivers. Secondary research questions investigated included (i) the presence of gender differences among spousal caregivers in the duration of care provided; (ii) gender differences among spousal caregivers in formal service use and unmet service needs; and (iii) whether support to care recipients in activities of daily living varied according to the gender of the spousal caregiver. The study was conducted over a 2-year period (2000-2002) in south-central Ontario, Canada. The study sample included 283 informal spousal caregivers (198 females, 85 males) each of whom were caring for a terminally ill spouse at the time they participated in a cross-sectional telephone survey. The analysis showed that females reported a significantly greater level of caregiving strain than males (t = -2.12, d.f. = 281, P = 0.035). When considering source of support in activities of daily living for the care recipient, differential assistance was noted on the basis of caregiver gender. Female caregivers had almost twice the odds of providing support in toileting-related tasks than male caregivers (odds ratio (OR) = 1.98, 95% confidence interval (CI) = 1.01-3.85, P = 0.044), while male caregivers had approximately twice the odds of providing support in mobility-related tasks (OR = 0.41, 95% CI = 0.21-0.81, P = 0.011). Care recipients who had a female caregiver had lower odds of receiving support from family and friends in tasks associated with personal care (OR = 0.17, 95% CI = 0.05-0.53, P = 0.002). To address gender differences in caregiving, a realistic home-based palliative care approach must take into account the importance of informal caregivers. © 2008 Blackwell Publishing Ltd.

Objectives: To determine the factors associated with a home death among older adults who received palliative care nursing home services in the home. Methods: The participants in this retrospective cohort study were 151 family caregivers of patients who had died approximately 9 months prior to the study telephone interview. The interview focused on the last year of life and covered two main areas, patient characteristics and informal caregiver characteristics. Results: Odds ratios [OR] and 95% confidence intervals [95% CI] were used to determine which of the 15 potential informal caregiver and seven patient predictor variables were associated with dying at home. Multivariate analysis revealed that the odds of dying at home were greater when the patient lived with a caregiver [OR = 7.85; 95% CI = (2.35, 26.27)], the patient stated a preference to die at home [OR= 6.51; 95% CI = (2.66,15.95)], and the family physician made home visits [OR = 4.79; 95% CI = (1.97,11.64)]. However the odds were lower for patients who had caregivers with fair to poor health status [OR = 0.22; 95% CI = (0.07, 0.65)] and for patients who used hospital palliative care beds [OR = 0.31; 95% CI = (0.12, 0.80)]. Discussion: The findings suggest that individuals who indicated a preference to die at home and resided with a healthy informal caregiver had better odds of dying at home. Home visits by a family physician were also associated with dying at home.
