Abstract
BACKGROUND Patients with chronic pain face significant barriers in finding clinicians to manage long-term opioid therapy (LTOT). For patients on LTOT, it is increasingly common to have them sign opioid treatment agreements (OTAs). OTAs enumerate the risks of opioids, as informed consent documents would, but also the requirements that patients must meet to receive LTOT. While there has been an ongoing scholarly discussion about the practical and ethical implications of OTA use in the abstract, little is known about how clinicians use them and if OTAs themselves modify clinician prescribing practices. OBJECTIVE To determine how clinicians use OTAs and the potential impacts of OTAs on opioid prescribing. DESIGN We conducted qualitative analysis of four focus groups of clinicians from a large Midwestern academic medical center. Groups were organized according to self-identified prescribing patterns: two groups for clinicians who identified as prescribers of LTOT, and two who did not. PARTICIPANTS 17 clinicians from General Internal Medicine, Family Medicine, and Palliative Care were recruited using purposive, convenience sampling. APPROACH Discussions were recorded, transcribed, and analyzed for themes using reflexive thematic analysis by a multidisciplinary team. KEY RESULTS Our analysis identified three main themes: (1) OTAs did not influence clinicians' decisions whether to use LTOT generally but did shape clinical decision-making for individual patients; (2) clinicians feel OTAs intensify the power they have over patients, though this was not uniformly judged as harmful; (3) there is a potential misalignment between the intended purposes of OTAs and their implementation. CONCLUSION This study reveals a complicated relationship between OTAs and access to pain management. While OTAs seem not to impact the clinicians' decisions about whether to use LTOT generally, they do sometimes influence prescribing decisions for individual patients. Clinicians shared complex views about OTAs' purposes, which shows the need for more clarity about how OTAs could be used to promote shared decision-making, joint accountability, informed consent, and patient education.

Long-term cancer outcomes after bariatric surgery. Obesity (Silver Spring) 2023; 31:2386-2397. [PMID: 37605634 PMCID: PMC10449359 DOI: 10.1002/oby.23812] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Accepted: 04/22/2023] [Indexed: 08/23/2023]
Abstract
OBJECTIVE Obesity is associated with increased cancer risk. Because of the substantial and sustained weight loss following bariatric surgery, postsurgical patients are ideal to study the association of weight loss and cancer. METHODS Retrospectively (1982-2019), 21,837 bariatric surgery patients (surgery, 1982-2018) were matched 1:1 by age, sex, and BMI with a nonsurgical comparison group. Procedures included gastric bypass, gastric banding, sleeve gastrectomy, and duodenal switch. Primary outcomes included cancer incidence and mortality, stratified by obesity- and non-obesity-related cancers, sex, cancer stage, and procedure. RESULTS Bariatric surgery patients had a 25% lower risk of developing any cancers compared with a nonsurgical comparison group (hazard ratio [HR] 0.75; 95% CI 0.69-0.81; p < 0.001). Cancer incidence was lower among female (HR 0.67; 95% CI 0.62-0.74; p < 0.001) but not male surgery patients, with the HR lower for females than for males (p < 0.001). Female surgery patients had a 41% lower risk for obesity-related cancers (i.e., breast, ovarian, uterine, and colon) compared with nonsurgical females (HR 0.59; 95% CI 0.52-0.66; p < 0.001). Cancer mortality was significantly lower after surgery in females (HR 0.53; 95% CI 0.44-0.64; p < 0.001). CONCLUSIONS Bariatric surgery was associated with lower all-cancer and obesity-related cancer incidence among female patients. Cancer mortality was significantly lower among females in the surgical group versus the nonsurgical group.

Online harms? Suicide-related online experience: a UK-wide case series study of young people who die by suicide. Psychol Med 2023; 53:4434-4445. [PMID: 35587034 PMCID: PMC10388316 DOI: 10.1017/s0033291722001258] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 02/22/2022] [Accepted: 04/14/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND Few studies have examined online experience by young people who die by suicide. METHODS A 3-year UK-wide consecutive case series of all young people aged 10-19 who died by suicide, based on national mortality data. We extracted information on the antecedents of suicide of 544 of these 595 deaths (91%) from official investigations, mainly inquests. RESULTS Suicide-related online experience was reported in 24% (n = 128/544) of suicide deaths in young people between 2014 and 2016, equivalent to 43 deaths per year, and was more common in girls than boys (OR 1.87, 95% CI 1.23-2.85, p = 0.003) and those identifying as LGBT (OR 2.35, 95% CI 1.10-5.05, p = 0.028). Searching for information about method was most common (n = 68, 13%), followed by posting suicidal ideas online (n = 57, 10%). Self-harm, bereavement (especially by suicide), social isolation, and mental and physical ill-health were more likely in those known to have suicide-related online experience compared to those who did not. 29 (5%) were bullied online, more often girls (OR 2.84, 1.34-6.04, p = 0.007). Online bullying often accompanied face-to-face bullying (n = 16/29, 67%). CONCLUSIONS Suicide-related online experience is a common, but likely underestimated, antecedent to suicide in young people. Although its causal role is unclear, it may influence suicidality in this population. Mental health professionals should be aware that suicide-related online experience - not limited to social media - is a potential risk for young patients, and may be linked to experiences offline. For public health, wider action is required on internet regulation and support for children and their families.

Pre-Operative Substance Use Disorder is Associated with Higher Risk of Long-Term Mortality Following Bariatric Surgery. Obes Surg 2023:10.1007/s11695-023-06564-9. [PMID: 37012503 DOI: 10.1007/s11695-023-06564-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 03/23/2023] [Accepted: 03/28/2023] [Indexed: 04/05/2023]
Abstract
PURPOSE Metabolic and bariatric surgery (MBS) has been associated with reduced all-cause mortality. While the number of subjects with substance use disorders (SUD) before MBS has been documented, the impact of pre-operative SUD on long-term mortality following MBS is unknown. This study assessed long-term mortality of patients with and without pre-operative SUD who underwent MBS. MATERIALS AND METHODS Two statewide databases were used for this study: Utah Bariatric Surgery Registry (UBSR) and the Utah Population Database. Subjects who underwent MBS between 1997 and 2018 were linked to death records (1997-2021) to identify any death and cause for death following MBS. All deaths (internal, external, and unknown reasons), internal deaths, and external deaths were the primary outcomes of the study. External causes of death included death from injury, poisoning, and suicide. Internal causes of death included deaths that were associated with natural causes such as heart disease, cancer, and infections. A total of 17,215 patients were included in the analysis. Cox regression was used to estimate hazard ratios (HR) of controlled covariates, including the pre-operative SUD. RESULTS The subjects with pre-operative SUD had a 2.47 times higher risk of death as compared to those without SUD (HR = 2.47, p < 0.01). Those with pre-operative SUD had a higher internal cause of death than those without SUD by 129% (HR = 2.29, p < 0.01) and 216% higher external mortality risk than those without pre-operative SUD (HR = 3.16, p < 0.01). CONCLUSION Pre-operative SUD was associated with higher hazards of all-cause, internal cause, and external cause mortality in patients who undergo bariatric surgery.

Abstract
OBJECTIVE This retrospective study incorporated long-term mortality results after different bariatric surgery procedures and for multiple age at surgery groups. METHODS Participants with bariatric surgery (surgery) and without (non-surgery) were matched (1:1) for age, sex, BMI, and surgery date with a driver license application/renewal date. Mortality rates were compared by Cox regression, stratified by sex, surgery type, and age at surgery. RESULTS Participants included 21,837 matched surgery and non-surgery pairs. Follow-up was up to 40 years (mean [SD], 13.2 [9.5] years). All-cause mortality was 16% lower in surgery compared with non-surgery groups (hazard ratio, 0.84; 95% CI: 0.79-0.90; p < 0.001). Significantly lower mortality after bariatric surgery was observed for both females and males. Mortality after surgery versus non-surgery decreased significantly by 29%, 43%, and 72% for cardiovascular disease, cancer, and diabetes, respectively. The hazard ratio for suicide was 2.4 times higher in surgery compared with non-surgery participants (95% CI: 1.57-3.68; p < 0.001), primarily in participants with ages at surgery between 18 and 34 years. CONCLUSIONS Reduced all-cause mortality was durable for multiple decades, for multiple bariatric surgical procedures, for females and males, and for greater than age 34 years at surgery. Rate of death from suicide was significantly higher in surgery versus non-surgery participants only in the youngest age at surgery participants.

Abstract
BACKGROUND Metabolic and bariatric surgery (MBS) is an effective treatment for obesity and may reduce mortality. Several factors are associated with higher mortality following MBS. The purpose of this study was to examine whether pre-operative arthritis was associated with long-term mortality following MBS. METHODS Using a retrospective cohort design, subjects who underwent MBS were identified from the Utah Bariatric Surgery Registry. These subjects were linked to the Utah Population Database. State death records from 1998 through 2021 were used to identify deaths following MBS. ICD-9/10 diagnosis codes were used to identify a pre-operative diagnosis of arthritis and to classify the cause of death. All causes of death, internal cause of death (e.g., diabetes, heart disease), and external cause of death (e.g., suicide) were defined as outcomes. Entropy balancing (EB) was applied to create weights to balance the baseline characteristics of the two groups. Weighted Cox proportional hazards regression was used to evaluate the association of pre-operative arthritis with long-term mortality following MBS. RESULTS The final sample included 15,112 patients. Among them, 36% had a pre-operative arthritis diagnosis. Average (SD) age was 48(12) years old at surgery, and 75% were female. Patients with pre-operative arthritis had 25% (p < 0.01) and 26% (p < 0.01) higher risk of all cause of death and internal cause of death, respectively, compared to patients without pre-operative arthritis. CONCLUSION Individuals with arthritis prior to MBS may have higher hazard of long-term mortality than those without pre-operative arthritis.

Abstract
BACKGROUND Dementia, including Alzheimer's disease, interfere with daily function and are one of the major causes of disability, institutionalization, and death. Obesity is associated with an increased risk of dementia. However, the effect of significant and sustained weight loss following bariatric surgery on dementia is not known. The purpose of this study was to assess the long-term risk of dementia following bariatric surgery. METHODS A surgical cohort was identified from the Utah Bariatric Surgery Registry and was linked to the Utah Population Database that includes electronic medical records, death records, and State Facility data. Adult subjects (≥ 18 years old) at time of surgery (1996-2016) were matched with non-surgical subjects. The final sample included 51,078 subjects (1:2 matching); surgery group n = 17,026; non-surgery subjects n = 34,052). Dementia were identified by ICD-9/10 diagnosis codes following surgery year or matched baseline year. Cox proportional hazard model was used to calculate the hazard ratio in the outcome between the groups. RESULTS Average (SD) age of the subjects was 42 (12) years old at surgery or matched baseline year, 78% were female and mean follow-up time was 10.5 years. 1.4% of the surgery group and 0.5% of the control group had an incidence of dementia. Controlling the covariates in the Cox regression, the surgery group had a higher risk for dementia incidence than the matched non-surgery subjects (HR = 1.33, p = 0.02). CONCLUSIONS The study showed an increased hazard for dementia in individuals who underwent bariatric surgery compared to matched non-surgical subjects. Additional long-term data is needed to verify this association.

Abstract
BACKGROUND Significant and sustained weight loss resulting from bariatric surgery have demonstrated clinical reduction in severe obesity-related pain. Subsequentially, post-surgical pain reduction may reduce pain medication use. However, clear evidence regarding use of prescribed pain medications before and after bariatric surgery is absent. METHODS Linking two state-wide databases, patients who underwent bariatric surgery between July 1, 2013 and December 31, 2015 were identified. Proportion tests were used to compare percent of patients with pain medication prescriptions 1 year before and 1 year after bariatric surgery. Logistic regression was used to identify baseline factors that were associated with pain medication use 1-year following surgery. RESULTS A total of 3535 bariatric surgical patients aged 18-64 years at surgery were identified. Of these patients, 1339 patients met the following study criteria: covered by private insurance; known pre-surgical BMI; and continuous enrollment with health plan(s) from 12-month pre-surgery to 13-month post-surgery. While comparison of average number of overall pain medication prescriptions before and after surgery did not change, from 3.46 to 3.32 prescriptions (p value = 0.26), opioid prescription use increased from 1.62 vs. 2.05 (p value < 0.01). Patients prescribed more types of pain medications before surgery were more likely to have prescribed pain medications after surgery. Patients prescribed benzodiazepines at baseline had higher odds being prescribed post-surgery corticosteroids (OR = 1.89, p value < 0.01), muscle relaxants (OR = 2.18, p value < 0.01), and opioids (OR = 3.06, p value = < 0.01) compared to patients without pre-surgery--prescribed benzodiazepine. CONCLUSION While comparison of average number of overall pain medication prescriptions before and after bariatric surgery did not decrease, opioid prescription increased post-surgery. Further studies are needed to examine whether post-surgery opioids are prescribed in lieu of or in tandem with other pain medication prescriptions.

Abstract
BACKGROUND/OBJECTIVES While an increased risk for substance use disorders (SUD) and also for several adverse pregnancy and birth outcomes in patients who have undergone bariatric surgery have been well documented when considered separately, an association between these important risk factors has not been investigated. This study explored the potential dependence of these two bariatric surgery-related risks. SUBJECTS/METHODS This study was a retrospective cohort study with adult women (18-45) who underwent bariatric surgery between 1996 and 2016 and who gave birth after surgery between 1996 and 2018. The study population consisted of 1849 post-bariatric surgery women with 3010 reported post-surgical births. Subjects with post-surgical, prenatal SUD were identified based on diagnosis codes extracted within the 10 months prior to delivery. Using random-effects logistic regression with retrospective cohort data, preterm birth, low birth weight, macrosomia, Caesarian delivery, congenital anomalies, and neonatal intensive care unit admission were considered as outcomes. RESULTS About 10% (n = 289) of women had an SUD diagnosis within 10 months prior to child delivery. Women with SUD during pregnancy had significantly more pregnancy and birth complications compared to women without SUD: preterm birth (OR = 2.08, p = 0.03, 95% CI: 1.07-4.03), low birth weight (OR = 3.41, p < 0.01, 95% CI: 1.99-5.84), Caesarian delivery (OR = 9.71, p < 0.01, 95% CI: 2.69-35.05), and neonatal intensive care unit admission (OR = 3.87, p < 0.01, 95% CI: 2.04-7.34). Women with SUD had lower risk for macrosomia than women without SUD (OR = 0.07, p = 0.02, 95% CI: 0.01-0.70). CONCLUSION Results from this study demonstrated that post-bariatric surgery women who had SUD during pregnancy had significantly more pregnancy- and birth-related complications than post-surgery pregnant women without SUD, despite the reduction in macrosomia. Where possible, greater prenatal surveillance of post-surgery women with SUD should be considered.

Abstract
Entrapment neuropathies affecting the sciatic nerve tract may adversely affect neural biomechanical features such as excursion and strain. There is a paucity of in vivo evidence examining the effects of forward bending upon sciatic nerve excursion and strain. The purpose of this study was to assess the reliability of ultrasound imaging in measuring sciatic nerve excursion and strain during forward bending movements. Secondary aims were to quantify sciatic nerve excursion and strain during forward bending movements and to assess the relationship between sciatic nerve excursion and movements of the hip and lumbar spine. The reliability of measuring sciatic nerve excursion was high to excellent whilst measurement of sciatic nerve strain was moderate. The amount of hip flexion, during forward bending, was a strong predictor of sciatic nerve excursion. These findings will support clinicians in the assessment and treatment of entrapment neuropathies, in addition to providing a foundation for future research.

A Shallow Water Ferrous-Hulled Shipwreck Reveals a Distinct Microbial Community. Front Microbiol 2020; 11:1897.

Abstract
Shipwrecks act as artificial reefs and provide a solid surface in aquatic systems for many different forms of life to attach to, especially microbial communities, making them a hotspot of biogeochemical cycling. Depending on the microbial community and surrounding environment, they may either contribute to the wreck’s preservation or deterioration. Even within a single wreck, preservation and deterioration processes may vary, suggesting that the microbial community may also vary. This study aimed to identify the differences through widespread sampling of the microbial communities associated with the Pappy Lane shipwreck (NC shipwreck site #PAS0001), a shallow water ferrous-hulled shipwreck in Pamlico Sound, North Carolina to determine if there are differences across the wreck as well as from its surrounding environment. Loose shipwreck debris, drilled shipcores, surrounding sediment, and seawater samples were collected from the Pappy Lane shipwreck to characterize the microbial communities on and around the shipwreck. Results indicated that the shipwreck samples were more similar to each other than the surrounding sediment and aquatic environments suggesting they have made a specialized niche associated with the shipwreck. There were differences between the microbial community across the shipwreck, including between visibly corroded and non-corroded shipwreck debris pieces. Relative abundance estimates for neutrophilic iron-oxidizing bacteria (FeOB), an organism that may contribute to deterioration through biocorrosion, revealed they are present across the shipwreck and at highest abundance on the samples containing visible corrosion products. Zetaproteobacteria, a known class of marine iron-oxidizers, were also found in higher abundance on shipwreck samples with visible corrosion. A novel Zetaproteobacteria strain, Mariprofundus ferrooxydans O1, was isolated from one of the shipwreck pieces and its genome analyzed to elucidate the functional potential of the organism. In addition to iron oxidation pathways, the isolate has the genomic potential to perform carbon fixation in both high and low oxygen environments, as well as perform nitrogen fixation, contributing to the overall biogeochemical cycling of nutrients and metals in the shipwreck ecosystem. By understanding the microbial communities associated with shallow water ferrous-hulled shipwrecks, better management strategies and preservation plans can be put into place to preserve these artificial reefs and non-renewable cultural resources.

Abstract
BACKGROUND In a time-constrained clinical environment, physicians cannot feasibly document all aspects of an office visit in the electronic health record (EHR). This is especially true for patients with multiple chronic conditions requiring complex clinical reasoning. It is unclear how physicians prioritize the documentation of health information in the EHR. OBJECTIVE The goal of this study is to examine documentation tradeoffs made by physicians when caring for complex patients by comparing the content of office visit conversations with resulting EHR documentation. METHODS We used grounded theory method of qualitative analysis to assess emergent themes in the transcripts of 10 office visits, and then compared the themes to documentation in the EHR. Differences between discussion and subsequent documentation of social and emotional health topics and each of the other key categories were compared using the Wilcoxon signed-rank test. RESULTS The categories that emerged included "chronic conditions," "acute/new problems," "disease prevention," and "social and emotional health." We found that when social and emotional topics were discussed in the office visit, it was documented in the medical record only 30.6% of the time. Chronic conditions, acute/new problems, and disease prevention were documented in the EHR between 87.5 and 91.7% of the time after discussion. The differences between discussion and documentation of social and emotional topics were significantly greater than the differences for chronic conditions, acute/new problems, and disease prevention (all p < 0.05). CONCLUSION Social and emotional factors, while extremely relevant to health management, are less likely than medical concerns to be documented after discussion in an office visit. This lack of documentation may hinder interdisciplinary communication between teams informing individualized therapeutic decisions during acute care handoffs, such as outpatient to inpatient care.

Significant polyp and early colorectal cancer - SPECC: The role of the Colorectal Cancer Clinical Nurse Specialist (CNS): promoting patient-centred care. Colorectal Dis 2019; 21 Suppl 1:32-36. [PMID: 30809911 DOI: 10.1111/codi.14501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2018] [Accepted: 09/23/2018] [Indexed: 02/08/2023]
Abstract
AIMS The colorectal Clinical Nurse Specialist (CNS) makes an important contribution to the care of individuals diagnosed with a significant polyp and early colorectal cancer (SPECC). METHODS This paper offers an expert opinion on the role of the CNS in SPECC, informed by relevant literature. RESULTS A CNS can support the patient through the diagnostic and treatment pathway acting as the patient's advocate as a core member of the multidisciplinary team. They will offer support and information to help patients understand their diagnosis, make choices about their available treatment options and help them to feel prepared for any treatment undertaken. CONCLUSION By providing care that is respectful of, and responsive to, individual patient preferences, needs and values, the CNS can play an important role in promoting patient-centred care.

Abstract
Background Over the last years many technical improvements have been made in hemodialysis treatment. Vascular access (VA) still remains an important problem. Although the use of indwelling vascular catheters is discouraged, in Europe there is an increasing use of them. The K/DOQI Guidelines recommend a native arteriovenous fistula (AVF) as VA of choice. As reported by DOPPS, there is considerable geographic variation in the distribution of type of VA used amongst hemodialysis patients. The aim of this study was to evaluate the time patients in four European countries have to wait before undergoing their first surgery for VA (AVF or graft). Methods All incident patients admitted to HD clinics located in Turkey, Italy, the UK and Portugal of the European FME clinics network between October 1, 2002 and September 30, 2004 were considered. Data were gained from the Clinical Database EuCliD®. Results 2,152 patients (males 55.9%, mean age 62.5±15.7 years, diabetics 27%) were selected. Italy and Portugal had a higher proportion of elderly patients. At time of admission, the proportion of patients starting dialysis with AVF ranged between 23% and 60% from Turkey to Italy respectively. Patients with an indwelling catheter at admission are expected to undergo VA surgery as soon as possible. After 3 months of follow-up, about 75% of all patients had undergone surgery, however in the UK less than 50% of the patients had had a VA procedure. Overall, males have significantly higher probability of undergoing surgery, whilst elderly patients have a lower probability (27% and 14% respectively). Conclusion Significant differences exist between countries in the time interval from referral to creation of VA. Health care system related problems seem to be the major reason to explain such differences. Patients in the UK have longer waiting times than the other countries studied.

Abstract
OBJECTIVES Processing necessary to remove immunogenic components of nerve allograft renders it acellular. Seeding with supportive cells may improve axon regeneration. We aim to identify the method associated with implantation of the greatest volume and most even distribution of cells. METHODS Hypodermic needle injection was compared to soaking in solution under both normal and pressurized conditions after micropuncture of the allograft. Distribution within the allograft was measured using an in vitro model of fluorescent beads, as well as cultured Schwann cells. RESULTS Injection treatment resulted in larger volumes and a more uniform cross-sectional distribution of implanted cells. Beads and cells behaved similarly relative to the measured outcomes. CONCLUSIONS Injection instills more cells in a more uniform distribution. In vivo testing may evaluate whether these techniques vary relative to cell survival, cell migration, and clinical outcomes. Size- and concentration-matched fluorescent beads may represent a viable model for analyzing cell implantation.

Abstract
BackgroundImproving the provision of palliative and end-of-life care is a priority for the NHS. Ensuring an appropriately managed ‘transition’ to a palliative approach for care when patients are likely to be entering the last year of life is central to current policy. Acute hospitals represent a significant site of palliative care delivery and specific guidance has been published regarding the management of palliative care transitions within this setting.Aims(1) to explore how transitions to a palliative care approach are managed and experienced in acute hospitals and to identify best practice from the perspective of clinicians and service users; (2) to examine the extent of potentially avoidable hospital admissions amongst hospital inpatients with palliative care needs.DesignA mixed-methods design was adopted in two hospitals in England, serving diverse patient populations. Methods included (1) two systematic reviews; (2) focus groups and interviews with 58 health-care professionals to explore barriers to, and facilitators of, palliative care transitions in hospital; (3) a hospital inpatient survey examining palliative care needs and aspects of management including a self-/proxy-completed questionnaire, a survey of medical and nursing staff and a case note review; (4) in-depth interviews with 15 patients with palliative care needs; (5) a retrospective case note review of all inpatients present in the hospital at the time of the survey who had died within the subsequent 12 months; and (6) focus groups with 83 key decision-makers to explore the implications of the findings for service delivery and policy.ResultsOf the 514 patients in the inpatient survey sample, just over one-third (n = 185, 36.0%) met one or more of the Gold Standards Framework (GSF) prognostic indicator criteria for palliative care needs. The most common GSF prognostic indicator was frailty, with almost one-third of patients (27%) meeting this criteria. Agreement between medical and nursing staff and the GSF with respect to identifying patients with palliative care needs was poor. In focus groups, health professionals reported difficulties in recognising that a patient had entered the last 12 months of life. In-depth interviews with patients found that many of those interviewed were unaware of their prognosis and showed little insight into what they could expect from the trajectory of their disease. The retrospective case note review found that 35 (7.2%) admissions were potentially avoidable. The potential annual cost saving across both hospitals of preventing these admissions was approximately £5.3M. However, a 2- or 3-day reduction in length of stay for these admissions would result in an annual cost saving of £21.6M or £32.4M respectively.ConclusionsPatients with palliative care needs represent a significant proportion of the hospital inpatient population. There is a significant gap between NHS policy regarding palliative and end-of-life care management in acute hospitals in England and current practice.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

Abstract
Research efforts over the past two decades have helped us better understand the biological mechanisms that lead to chronic pain. Despite this, there has been limited progress in developing novel analgesics to treat sufferers of persistent pain conditions, who may account for as many as one-fifth of the population. A re-evaluation of the strategies used to discover pain-relieving drugs is needed to meet this widespread clinical need. Here, we discuss the merits of pursuing peripherally acting pain mediators. We review the significant clinical evidence that neuronal activity from the periphery is a major contributor to painful symptom production and that peripheral mediators play a substantial role in this aberrant nociceptor activity. We discuss the clinical benefits of blocking individual known mediators and describe our own approach to identify novel mediators.

Abstract
BACKGROUND The 'hygiene hypothesis' proposes that infections in infancy protect against hay fever (HF). We investigated infections during infancy in relation to HF, including rarer ones not previously researched in this context, while examining the role of potential confounding variables. METHODS From birth cohorts derived within the General Practice Research Database (GPRD) and Doctors Independent Network (DIN) database of computerized patient records from UK general practice, we selected 3549 case-control pairs, matched for practice, age, sex and control follow-up to case diagnosis. Conditional logistic regressions were fitted for each of 30 infections; behavioural problems (BP) acted as a control condition unrelated to HF. Odds ratios (OR), adjusted for consultation frequency were pooled across the databases using fixed effect models. We also adjusted for sibship size in GPRD and a socioeconomic marker in DIN. RESULTS Upper respiratory tract infections, diarrhoea and vomiting and acute otitis media in infancy were each related with a moderately increased risk of HF in both databases, as were BP. These associations were lost on adjustment for consultation frequency. Only bronchiolitis was significantly associated with a reduced pooled risk of HF after adjustment for consultations (OR = 0.8). Adjustment for sibship size in GPRD and a socioeconomic marker in DIN had little impact on the OR. CONCLUSIONS Of 30 infectious illnesses investigated, none had strong or consistent associations with HF after adjustment for consultation frequency. Except for bronchiolitis, possibly a chance finding, none of the clinically apparent infections considered appear to have an important role in allergy prevention.

Abstract
BACKGROUND Statins, antiplatelet drugs, beta-blockers and ACE inhibitors may produce marked benefits in secondary prevention of ischaemic heart disease (IHD), especially in combination. OBJECTIVE To examine trends in treatment and factors associated with treatment using a population-based general practice database. DESIGN Analysis of routinely collected computerised data from 201 general practices using iSOFT software contributing to the DIN-LINK database. SETTING AND PATIENTS Subjects aged >or=35 years and registered with the practices; on average, 30 000 men and 21 000 women with IHD each year. MAIN OUTCOME MEASURE Percentage of subjects with IHD receiving individual drugs and combined treatment in any given year. RESULTS Between 1994 and 2005 use of drugs for secondary prevention increased markedly. By 2005, 80% of men and 70% of women were receiving a statin, 75% and 74% were receiving antiplatelet drugs, 55% and 48% were receiving beta-blockers and 57% and 51% were receiving an ACE inhibitor; 55% of men and 46% of women were receiving a statin, antiplatelet drug and either beta-blocker or ACE inhibitor, of whom just under half were receiving all four classes of drug. Gender differences were largely explained by more severe disease in men. In 2005, subjects less likely to receive combination therapy were older, had not had a myocardial infarction or revascularisation, and lacked comorbidities such as diabetes or hypertension. CONCLUSIONS Despite high levels of statin and antiplatelet prescribing, opportunities exist for increasing the benefits of secondary prevention, especially through the wider use of combined treatments. Future targets could usefully include combination therapy.

Abstract
BACKGROUND It has been hypothesized that early-life exposure to vaccinations, infections or antibacterials influence allergic disease development. Concurrent exposure to grass pollens may alter any effect. OBJECTIVE To test the hypothesis that exposure to antibacterials, vaccinations (DTP or MMR) or specific infections during the first grass pollen seasons of life influences the risk of hayfever more than at any other time of the year. METHODS Nested case-control studies were based on birth cohorts within two large databases of computerized patient records from UK general practices: the General Practice Research Database (GPRD) and Doctors' Independent Network (DIN). Seven thousand ninety-eight hayfever cases, diagnosed after age 2, were matched to controls for practice, age, sex and follow-up of control to case ascertainment date. Conditional logistic regression was used to compare exposure by age 1 (age 2 for MMR) inside vs. outside the grass pollen season (May, June, July). Odds ratios (ORs) were pooled across databases. RESULTS There were no associations in either database between MMR during vs. outside the grass pollen season and later hayfever. Of 23 infections studied, none were statistically significant; although analyses for the less common conditions were limited by low statistical power. The pooled OR for hayfever comparing exposure to antibacterials only in the grass pollen season with only outside it was 1.20 (95% CI 0.98-1.47) and for DTP was 0.84 (95% CI 0.72-0.98). CONCLUSION Although an interaction between early exposure to microbial agents and concurrent grass pollen exposure on hayfever risk seemed plausible, there was little evidence to support it across a range of analyses. However, the effect of DTP though weak deserves further study.

Abstract
OBJECTIVES We perform a retrospective review of renal tumors operated with a maximum size of 4 cm to determine if the diagnostic methodology was adequate, the TMN staging prognostic accuracy (UICC 2002) and the goal surgical treatment. MATERIAL AND METHOD Between 1984 to 2005, 78 renal units form 74 patients (4 bilateral synchronous) operated at the Service of Urology of the Hospital Alemán de Buenos Aires. Age distribution, sex, presentation form (incidental and symptomatic), diagnostic methodology, laboratory variables, surgical treatment (partial or radical surgery), histopathology, Fuhrman grade, tumor size, bilaterality, multicentricity, TNM staging, evolution and survival (Kaplan Meier) were analyzed. RESULTS 78 renal units from a total of 192, 40.62% were analyzed. The median age was 58.72 years. 69% were male and 31% female. The presentation form was 91.90 % incidental and symptomatic 8.10% (Hematuria in 5 and lung metastasis in 1). The diagnosis was performing with ultrasound and CT scan 63 cases, in 4 was also used resonance magnetic imaging (RMI) and in 7 ultrasound and RMI. Arteriography was used in 11 cases, 3 showed tumor and 8 were normal. Biopsy was performing in 5 cases, all positive for clear cells carcinoma. Globular sedimentation was the only one laboratory abnormality in 12 cases. Surgical treatment was radical surgery in 35 renal units (44.87%) and conservative surgery in 43 units (55.13%). Pathology clear cells carcinoma (CCC) 79.48%, papillary carcinoma 1.28%, angiomyolipoma (AML) 8.97%, oncocytoma 7.69% and adenoma 2.56%. The Fuhrman grade was 1 in 76.19%; 2 in 20.63% and 3 in 3.18%. Bilateral tumor were found in 4 cases 2 CCC, 1 CCC and AML and 1 CCC and adenoma. Tumor median size was 2.93 cm. Staging was T1a 96.82%, T3a 1.59% and T3aM+ 1.59%. Follow-up could be made in 54 of 61 cases. At median follow-up of 52.25 months, 50 cases were disease free, 3 died by progression at 18, 33 and 82 months and all of them were symptomatic tumors, 1 died by a non related cause. Survival rate was 94%. CONCLUSIONS 1)Ultrasound and CT scan obtained a highest diagnostic accuracy for solid renal mass. Biopsy in selective cases could contribute to achieve a correct treatment strategy. 2) Conservative surgery was the goal treatment in selected tumors up to 4 cm. and we believe that TNM staging should contemplate the presentation form to improve the prognostic value.

Abstract
A survey of 72 thoroughbred trainers in several regions of NSW was conducted to better define current grain feeding practices, and the risks involved with grain feeding in the Australian thoroughbred racing industry. Results from the survey indicate that horses in the industry are currently being fed an average of 7.3 +/- 0.23 kg of grain concentrate per day, with oats, commercial pre-mixed diets and corn most commonly used. The feeding of extruded, micronised and steam flaked grains was uncommon. The results of grain and faecal sample analyses conducted during the survey indicate that incomplete starch digestion in the equine small intestine and subsequent hindgut starch fermentation and low hindgut pH are common. These observations quantify the adverse impact of current grain feeding practices on faecal measures of gut health and demonstrate that when selecting grains for use in the thoroughbred racehorse, greater emphasis should be placed on the starch digestibility characteristics of grains.

Abstract
When, if ever, should we allow an extremely premature baby to die? The paper explains how that would be answered if we are guided by three reasonable assumptions. (1) The value a person's life has is primarily the value it has for that person, rather than a value it has in itself. (2) All competent persons have a right to decide for themselves whether their lives are to be prolonged. (3) Parents have a right to treat their children as they choose, so long as they neither abuse them nor neglect them.

Abstract
OBJECTIVES To examine trends in the prevalence of diagnosed atrial fibrillation (AF), its treatment with oral anticoagulants between 1994 and 2003, and predictors of anticoagulant treatment in 2003. METHODS Analysis of electronic data from 131 general practices (about one million registered patients annually) contributing to the DIN-LINK database. RESULTS From 1994 to 2003 the prevalence of "active" AF rose from 0.78% to 1.31% in men and from 0.79% to 1.15% in women. The proportion of patients with AF taking anticoagulants rose from 25% to 53% in men and from 21% to 40% in women. Most others received antiplatelets. The likelihood of receiving anticoagulants was greater for men and with increasing stroke risk. It decreased sharply with age after 75 years. Socioeconomic status, urbanisation and region had no influence. Non-steroidal anti-inflammatory drugs, antiplatelet drugs and ulcer healing drugs were associated with reduced likelihood of receiving anticoagulants, as were peptic ulcers, chronic gut disorders, anaemias, psychoses and poor compliance. Anticoagulant treatment was associated with several cardiovascular co-morbidities and drugs, possibly due to secondary care treatment. Nevertheless, only 56.5% of patients at very high risk of stroke were taking anticoagulants in 2003, whereas 38.2% of patients at low risk of stroke received anticoagulants. CONCLUSIONS This study confirms previously observed trends of increasing AF prevalence and warfarin treatment. Many patients who may benefit from anticoagulation still do not receive it, whereas others at lower risk of stroke do. The lower likelihood of women receiving anticoagulants is of particular concern.

Abstract
BACKGROUND Suggestions that immunisation influences allergic disease risk, either positively (pertussis) or negatively (BCG) are of concern for vaccination policy. AIMS To determine whether DTP, MMR, and BCG vaccination in infancy influenced hay fever risk. METHODS Case-control study of 7098 hay fever cases and controls, within two primary care databases. One control per case was matched for practice, age, and sex. Odds ratios (OR) were derived using conditional logistic regression. RESULTS Compared to those completing in month 5 (base group) (39.3%), DTP unvaccinated children (4.3%) had a similar risk of hay fever (OR = 0.94, 95% CI 0.73 to 1.23). However, those completing after 12 months (4.2%) had a reduced risk (OR = 0.60, 95% CI 0.45 to 0.76) compared to the base group. Compared to those vaccinated in month 14 (base group) (29.5%), MMR unvaccinated children (2.3%) had an OR of 0.79 (95% CI 0.58 to 1.08). Completion of MMR after two years was associated with reduced hay fever risk (OR = 0.62, 95% CI 0.48 to 0.80) compared to the base group. The effects of late immunisation with DTP and MMR were independent. Those vaccinated with BCG by age 2 (2.4%) had an odds ratio of 1.28 (95% CI 0.96 to 1.70). Adjustment for consulting behaviour, social factors, or sibship size did not alter these associations. CONCLUSIONS Immunisation against DTP or MMR does not increase the risk of hay fever. The lower confidence limit for BCG vaccination contradicts the hypothesised protective effect. The reduced risk of hay fever among children immunised late may be explained by a third factor causing both postponement and reduced risk such as intercurrent febrile illnesses.

A comparison of the recording of 30 common childhood conditions in the Doctor's Independent Network and General Practice Research Databases. HEALTH STATISTICS QUARTERLY 2004:21-31.

Abstract
In this article we compare the recording of 30 common childhood conditions in two general practice databases of anonymised computerised medical records based on fundamentally different systems--the Doctor's Independent Network (DIN) database (Torex system) and the General Practice Research Database (GPRD) (In Practice Systems). Analysing the records of all children born 1990-1993 and followed for 5 years we found comparable results for most conditions, but differences between the hierarchical structures of the diagnostic coding systems (Read in DIN, OXMIS in GPRD) led to some differences between the databases. Practice variation was marked, but comparable between databases. Variation was greatest in conditions that are poorly defined clinically.

Abstract
BACKGROUND Theoretically, antibacterial agents in early life might influence allergic sensitization in two ways: (i) as an indicator of infectious illness, they might be expected to protect against allergy; (ii) alternatively they might increase the risk through effects on the commensal bowel flora. Epidemiological evidence linking the prescription of antibacterial agents in early life to the subsequent development of hayfever is conflicting. OBJECTIVE To establish definitively whether an association exists between early-life antibacterial exposure and childhood hayfever diagnosis. METHODS Nested case-control studies were based on birth cohorts of children identified within two large UK general practice databases of electronic patient records. One hundred and sixteen thousand and four hundred and ninety-three children from 605 general practices were identified as being continuously registered from birth to at least age 5 years. Seven thousand and ninety-eight cases were diagnosed with hayfever after the age of 2 years. One control per case was matched for practice, birth month, sex and still being registered on case diagnosis date. Odds ratios were derived from conditional logistic regressions within each database followed by pooling using a fixed-effect model. RESULTS The pooled odds ratio for hayfever was 1.11, 95% CI (1.03-1.20) if exposed to antibacterials in the first year of life, 1.35 (1.25-1.46) in year 2 and 1.47 (1.37-1.59) in year 3. Adjusting for consultation frequency reduced these odds ratios to 0.92, 1.05 and 1.10, respectively. There was no evidence that broader spectrum antibacterials, exposure in any specific month of year 1 or in the grass pollen season influenced the risk of hayfever. CONCLUSION These data exclude any important effect of antibacterial exposure in infancy on subsequent hayfever risk. Associations reported in earlier studies have likely been exaggerated through publication bias and by lack of control for the tendency of some families to consult frequently for a range of conditions.

Abstract
OBJECTIVE To study trends in the use of lipid lowering drugs in the UK, and to assess which patient factors influence prescribing. METHODS Routinely collected computerised medical data were analysed from 142 general practices across England and Wales that provide data for the Doctors' Independent Network database. Subjects included were people aged 35 years or more with treated ischaemic heart disease, averaging annually over 30,000. The temporal trend from 1994 to 2001 in prescription of lipid lowering drugs and daily statin dose and the odds ratios (ORs) for receiving a statin prescription in 1998 were examined. RESULTS Lipid lowering drug prescribing increased greatly over time, entirely because of statins, so that in 2001 56.3% of men and 41.1% of women with ischaemic heart disease received lipid lowering drugs. However, 33% of these patients were on a < 20 mg simvastatin daily equivalent. In 1998 the OR for receiving a statin fell from 1 at age 55-64 to 0.64 at 65-74 and 0.16 at 75-84 years. The age effect was similar in those without major comorbidity. Revascularised patients were much more likely to receive a statin than those with angina (OR 3.92, 95% confidence interval (CI) 3.57 to 4.31). Men were more likely to receive a statin than women (OR 1.62, 95% CI 1.54 to 1.71) but this difference disappeared after adjustment for age and severity of disease (OR 1.06). Geographical region had little effect but there was a very weak socioeconomic gradient. CONCLUSIONS Although prescribing has increased, many patients who may benefit from lipid lowering drugs either do not receive it or are undertreated, possibly because of lack of awareness of the relative potency of the different statins. Patients with angina and the elderly are less likely to receive treatment that may prevent a coronary event.

Abstract
OBJECTIVE Analysis of data from the National Survey of Coronary Heart Disease patients to develop a core measure of patient experiences of health care. A secondary purpose was to determine whether a single summary index figure could be generated from the instrument. DESIGN The data reported here comes from the survey of coronary heart disease (CHD) patients, which was the second in the programme of National Surveys of National Health Service (NHS) patients. It took place during 1999. After an in-patient episode for CHD, questionnaires were mailed out to patients with a covering letter and a pre-paid stamped addressed envelope. Those patients who did not reply within two weeks of the initial mailing were sent a reminder letter and, if this elicited no reply within two weeks, they were sent another copy of the questionnaire. SAMPLE Of the 116,872 patients who were sent questionnaires, 3399 proved to be ineligible or out-of scope to the survey. Responses were gained from 84,310 (74.3% of eligible respondents). RESULTS Reliability analysis supported the existence of seven dimensions which seem to be tapping distinct underlying phenomena: hospital environment, information and communication, patient involvement, coordination of care, discharge and transition, and pain. Higher order factor analysis indicated these dimensions constituted one factor and, consequently, can be summed to create an index figure. The construct validity of the measure was assessed, and it distinguished between groups as was hypothesised. CONCLUSIONS The dimensions of the questionnaire have high internal reliability. Both the dimensions of the instrument and the index score were found to have high construct validity. The instrument provides a core set of issues that should be covered when assessing the quality of care for hospital patients with coronary heart disease.
