International Survey of Psychosocial Care for Cancer Survivors in Low-/Middle- and High-Income Countries: Current Practices, Barriers, and Facilitators to Care. JCO Glob Oncol 2024; 10:e2300418. [PMID: 38781550 DOI: 10.1200/go.23.00418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 01/24/2024] [Accepted: 03/26/2024] [Indexed: 05/25/2024] Open
Abstract
PURPOSE The number of cancer survivors living with and beyond cancer treatment is rising globally. It is fundamental to understand the extent and type of psychosocial care services offered worldwide. We evaluated models of cancer survivorship care, psychosocial care practices in the post-treatment survivorship phase, and barriers/facilitators to delivery of psychosocial care services, including in low- and middle-income countries (LMICs). METHODS The International Psycho-Oncology Society (IPOS) Survivorship Special Interest Group led a cross-sectional online survey between March and November 2022. Health care professionals and researchers in psycho-oncology were invited through the IPOS global membership, social media, and snowballing. The survey was administered to individuals but included questions related to practices in their country at a national level. RESULTS Two hundred eighty-three respondents from 37 countries participated (40% from LMICs), with a median of 12 years of experience (IQR, 6-20) in the psycho-oncology field. Participants reported that the most common elements of routine survivorship care were related to the prevention/management of recurrences/new cancers (74%), physical late effects (59%), and chronic medical conditions (53%), whereas surveillance/management of psychosocial late effects (27%) and psychosocial/supportive care (25%) were least common. Service availability was more commonly reported in high-income countries (HICs) than LMICs related to reproductive health (29% v 17%), genetic counseling/support (40% v 20%), and identifying/managing distress (39% v 26%) and pain (66% v 48%). Key barriers included providers focusing on treatment not survivorship (57%), medical not psychosocial care (60%), and a lack of allied health providers to deliver psychosocial care (59%). CONCLUSION The psychosocial needs of people living with cancer are not adequately available and/or provided in post-treatment survivorship even in HICs, because of barriers at patient, provider, and system levels.

Psychosocial care for cancer survivors: A global review of national cancer control plans. Psychooncology 2023; 32:1684-1693. [PMID: 37749754 DOI: 10.1002/pon.6218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 08/30/2023] [Accepted: 09/11/2023] [Indexed: 09/27/2023]
Abstract
OBJECTIVE National Cancer Control Plans (NCCPs) are high-level policy documents that prioritise actions to be taken to improve cancer control activities. As the number of cancer survivors grows globally, there is an urgent need to assess whether and how psychosocial care across the cancer care continuum is included in NCCPs. This review aimed to ascertain the extent to which NCCPs referenced psycho-oncology care for cancer survivors in the post-treatment phase. METHODS NCCPs were obtained from the International Cancer Control Partnership (ICCP) portal (in November 2021) and reviewed in two phases. In Phase 1, all available NCCPs were screened to determine whether they mentioned psycho-oncology or survivorship. In Phase 2, reviewers extracted data from the NCCPs identified in Phase 1 on the degree that each plan articulated objectives/goals to improve psychosocial care in the post-treatment survivorship phase. RESULTS We screened 237 NCCPs. Of these, initial potential reference to psycho-oncology and survivorship content were identified in 97 plans (41%). In Phase 1, 57/97 (59%) had reference to psycho-oncology or survivorship content within defined criteria. In Phase 2, 27/97 (28%) had little mention of psycho-oncology specifically in survivorship, 47/97 (48%) had some (general or brief) mention, and the remaining 23/97 (24%) had substantial content/specific sections and clearly articulated goals and/or objectives. Common goals for improving psychosocial care in the post-treatment period included building capacity of healthcare professionals, implementing rehabilitation models, and increasing the utilisation of community services. CONCLUSIONS Most NCCPs did not reference psycho-oncology and only one-quarter contained clear objectives specifically in the post-treatment survivorship phase.

Abstract
The Covid-19 pandemic presented a wide range of challenges to cancer control. People with possible symptoms of cancer were considered less likely to present for investigation. Patients with cancer were concerned about increased risk of illness or death from this novel virus. Cancer services had to ensure continued delivery of time-sensitive care. Public health skills and leadership have been key to Ireland's National Cancer Control Programme's COVID response. The multi-disciplinary skill set within the Programme includes an understanding of health protection principles, experience in rapid service redesign, monitoring of service delivery, patient and public communication, advocacy and guidance development, all of which have been integral to the pandemic response. Specific areas addressed include: rapid turnaround of guidance documents for cancer services, to minimise Covid-19 risk; patient information materials for those on treatment or with a history of cancer; development of novel service delivery mechanisms, such as a virtual national psycho-oncology service; a media campaign to combat decreased presentations with possible cancer and to reassure those currently on treatment; development of pre-surgical cocooning guidance and testing pathway; advocating for prioritisation of time-sensitive cancer diagnosis and treatment, and the wider health & wellbeing needs of those cocooning; advocating for and supporting the implementation of priority vaccination for those undergoing cancer treatment. Cross-sectoral collaboration has been facilitated by existing networks and relationships, allowing rapid responses to be deployed and actioned. The leaner guidance development process employed during the pandemic enabled timely response. A two-way communication system with cancer services allowed swift cascade of information and gathering of intelligence which empowered action. Learning from the cancer setting was transferable to other high-risk groups. Key messages The potential impact of the pandemic on non-COVID care was far reaching, including at all stages of the cancer patient journey, from pre-diagnosis to living with or beyond cancer. The programmatic approach to cancer control in Ireland facilitated concerted efforts to respond to the challenges posed by the pandemic.

Abstract
Abstract
Background
Major bleeding after acute coronary syndrome (ACS) predicts a poor outcome. Although predictors of major bleeding following ACS have been validated, these have been mostly in clinical trial populations and few contemporary analyses have been undertaken in clinical practise
Methods
Major bleeding was assessed in a national study of ACS and antiplatelet choice. A total of 5116 consecutive patients [Clopidogrel (n 2,491, 2011–13) and Ticagrelor (n 2,625, 2013–16)] were enrolled in 5 UK hospitals. Clinical outcomes were identified from a national coding database (n=59.5 million) with bleeding events tracked to 11 health care facilities. Bleed severity was independently adjudicated by 2 consultant cardiologists, blinded to antiplatelet, sequence and year. Bleeding events were categorised using BARC 3–5 and PLATO criteria. A logistic regression analysis was used to define independent predictors of bleeding.
Results
The median age was 68 (IQR57–78, 30.5%>75), 34% were female. 39% underwent PCI and 13% coronary artery bypass surgery. Clinical outcome data was 100% complete. 1-year mortality was 12.9%. Of 1193 icd10 codes for bleeding or anaemia 165 (3.2%) and 193 (3.8%) patients were adjudicated to have suffered a BARC 3–5 and PLATO major bleeding respectively. Independent predictors common between PLATO major and BARC 3–5 bleeding, in the year following ACS, were CRUSADE score >40 (OR 1.63, CI 1.1–2.4, p=0.008) moderate left ventricular systolic dysfunction (OR, 1.65, CI: 1.2–2.4, p=0.006), age (OR per year increase in age 1.03, CI 1.02–1.05, p<0.001) and subsequent coronary artery bypass surgery (OR 2.6, CI 1.8–3.8, p<0.001)
Conclusion
In a broad real-world population of ACS, CRUSADE score >40, incorporating simple clinical and laboratory criteria, remained an independent predictor of major bleeding using 2 internationally recognised bleed criteria

Abstract
Abstract
Background
Combining HSTnT (high sensitive troponin T) values at low levels with composite risk scores may improve early safe, discharge in suspected acute coronary syndromes (ACS). We tested this hypothesis by a prospective study of 3016 consecutive patients with suspected ACS in 2 large hospitals.
Methods
Consecutive chest pain (CP) presentations with HSTnT sampled and ECG undertaken at presentation were prospectively defined in 2 time periods (2011-12, n=1642 [derivation] 2018, n=1376 [validation]).
The HstnT input was modified: dichotomous HSTnT input was lowered to <5 (limit of detection, LOD) or ≥5ng/l (mod TIMI and GRACE), HEART score was re-calibrated (<5 = 0 [LOD], ≥5–14 = 1, >14 = 2 [99th percentile]). All biomarker positive CP index and re-admissions to any regional hospital (catchment population 2.6 million) were independently adjudicated for MI by 2 experienced physicians. Primary outcome was MACE (adjudicated type 1 MI, unplanned coronary revascularisation and all cause death) at 6 weeks.
Results
In the 2 cohorts demographic factors were similar: median age 59 and 56, male 52% and 52%, previous MI 20% and 14% for 2011-12 and 2018 respectively. At 6 weeks 180 (11%) and 75 (5.4%) suffered type 1 MI and 211 (12.9%) and 92 (6.7%) patients suffered MACE in the 2011-12 and 2018 cohorts respectively.
Only Mod HEART ≤3 and undetectable HSTnT, with a nonischaemic ECG, achieved prespecified NPV of >99.5% in both derivation and validation cohorts (table). However Modified HEART ≤3 score could discharge approximately 12% more patients as compared to undetectable HSTnT strategy.
Conclusion
Modified HEART score ≤3, with the use of a single HSTnT, appears the optimum early discharge strategy for suspected ACS

A cost comparison study to review community versus acute hospital models of nursing care delivered to oncology patients. Eur J Oncol Nurs 2020; 49:101842. [PMID: 33126156 DOI: 10.1016/j.ejon.2020.101842] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 09/21/2020] [Accepted: 09/25/2020] [Indexed: 12/31/2022]
Abstract
PURPOSE Ireland's Sláintecare health plan is placing an increased focus on primary care. A community oncology nursing programme was developed to train community nurses to deliver care in the community. While the initial pilot was proven to be clinically safe, no cost evaluation was carried out. This study aims to compare the costs of providing cancer support services in a day-ward versus in the community. METHODS 183 interventions (40 in day-ward and 143 in community) were timed and costed using healthcare professional salaries and the Human Capital method. RESULTS From the healthcare provider perspective, the day-ward was a significantly cheaper option by an average of €17.13 (95% CI €13.72 - €20.54, p < 0.001). From the societal perspective, the community option was cheaper by an average of €2.77 (95% CI -€3.02 - €8.55), although this was a non-significant finding. Sensitivity analyses indicate that the community service may be significantly cheaper from the societal perspective. CONCLUSIONS Given the demand for cost-viable options for primary care services, this programme may represent a national option for cancer care in Ireland when viewed from the societal perspective.

Abstract
Objective To establish the major expressed psychological needs of adult survivors of childhood cancer living in Ireland. Methods Seven focus groups were conducted with adult survivors of childhood cancer and their parents in 2018. Survivors were invited to participate if they were diagnosed with cancer before age 18. Results Thirty‐three participants (15 survivors, 18 parents; 27 female, 6 male) were included. They had experienced a range of haematological and solid tumours. Five themes were generated: (a) Enduring psychological impact on survivors; many survivors experience delayed trauma and mental health crises in adulthood. (b) Enduring psychological impact on family members; parents and siblings have unmet psychological needs relating to the family's experience of cancer. (c) Enduring impact on family dynamics; survivors and parents expressed fear and guilt relating to cancer which impacted on family interactions. (d) Challenges accessing support; psychological support services are inadequate to meet expressed needs. (e) Desired model of care; no single service model appeals to all survivors, and flexibility is required in the delivery of psychological support. Conclusion Adult survivors of childhood cancer and their family members experience enduring psychological effects relating to their diagnosis and treatment. Psychological support services are inadequate to meet the expressed needs of this growing population.

Abstract
Abstract
Introduction
Sleep study volume in our system has increased by 23% from 2017 to 2019 which makes unfilled sleep beds a significant concern. Cancellation rate impacts our sleep bed access. We hypothesized cancellation can be improved through quality improvement process which could ultimately lead to improve patient satisfaction.
Methods
A multi-disciplinary team was assembled to examine potential contributing factors. Using the Model for Improvement we developed, tested and implemented interventions using tools such as PDSA cycles, process map and a simplified FMEA (Failure Modes and Effects Analysis). A Key Driver Diagram helped guide our journey to improve the cancellation rate. We developed a Parent Advisory Group to help us with ideas to identify how we could improve the cancellation rate.
Results
The cancellation was 21% prior to the implementation of our interventions. To improve these measures, we have implemented several interventions. The content of our sleep study preparation handbook was improved, increased distribution of the education handbook and developed a series of sleep study videos which are available for viewing prior to the study to prepare patients and families. In addition, we standardized our process of reminder calls in the call center and sleep lab by defining roles and responsibilities. This improved our ability to answer questions and identify and mitigate barriers they may have. We implemented transportation assistance to patients who have transportation barriers and created a waitlist protocol to assist families with a preferred date. After 2 years of interventions, the cancellation rate has decreased from 21% to 14.7%. Interestingly, as we improved our cancellation rate, the overall patient satisfaction has been improved from 83% to 88%.
Conclusion
Using the Model for Improvement, we improved education, communication and scheduling processes, which has reduced cancellation rate and consequently improved patient satisfaction.

Seasonal Inactivated Influenza Vaccination in Oncology Settings. IRISH MEDICAL JOURNAL 2019; 112:983. [PMID: 31647211] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/10/2023]
Abstract
Aims The aims of this study were to establish the uptake rate of seasonal influenza vaccine amongst oncology healthcare workers (HCWs) during the 2016/17 influenza season and to ascertain which factors were associated with or predicted vaccination, along with determining if national guidance regarding influenza vaccination for cancer patients is implemented. Methods A national cross-sectional study was carried out on clinical staff working in oncology day wards. Results Vaccine uptake during the 2016/17 season among oncology day ward staff was 48%. Fear of vaccine side-effects, believing that if one is healthy, there is no need for vaccination, and doubt about vaccine effectiveness negatively predicted vaccination. Most staff (87.6%) recommend vaccination to some or all patients. Conclusion Every effort should be made to ensure HCWs are given the opportunity to get vaccinated, provided with evidence of vaccine effectiveness and safety and empowered to recommend influenza vaccination to their patients.

Abstract
Background and context: As part of the National Cancer Strategy 2017-2026, the NCCP aims to improve the experience and care for cancer survivors. A key objective of survivorship care is to empower patients to achieve their best possible health outcomes while living with and beyond a diagnosis of cancer. Aim: To develop a guide to provide a support on sexual well-being for women who have completed cancer treatment of breast cancer; gynecologic cancer; bowel, rectal and anal cancer; or bladder cancer. Strategy/Tactics: A project design team was established with stakeholders including healthcare professionals and patients. Program/Policy process: The guides were designed to facilitate conversation around what is a sensitive subject for many people. Having cancer may change the relationships a cancer survivor has with their family and friends; it is natural to need some time to adjust. But while cancer treatment may affect sexuality, sex life doesn't have to end. The guide was reviewed by patient groups prior to printing. It is approved by National Adult Literacy Agency (NALA). The guide was nationally distributed to all clinical areas and is available on the Web. Outcomes: The final publication is entitled Sexual Well-Being After Breast or Pelvic Cancer Treatment: A Guide for Women. It gives details of treatments that may help improve sexual well-being and encourages women to be their own strongest resource. It includes advice on how to talk about sexual well-being, how to create physical and emotional intimacy, and what to do if you are not in a sexual relationship but would like to be. The guide is a companion to the previously published Information for Men on Sexual Well-Being After Pelvic Cancer Treatment, which has been widely used by men to understand the sexual changes caused by cancer treatment. The guide was launched in January 2018. With support from HSE communications it was promoted across social media. It received a positive response with the guides requested nationally. The guide was also distributed to all the cancer centers, support services, and primary care centers. What was learned: Healthcare professionals find it difficult to discuss sexuality with their patients and this booklet allows sexuality to be discussed. Workshops will be required with healthcare professionals to empower themselves and their patients to address the issue of sexuality in survivorship.

Abstract
Biomimetic scaffolds hold great promise for therapeutic repair of cartilage, but although most scaffolds are tested with cells in vitro, there are very few ex vivo models (EVMs) where adult cartilage and scaffolds are co-cultured to optimize their interaction prior to in vivo studies. This study describes a simple, non-compressive method that is applicable to mammalian or human cartilage and provides a reasonable throughput of samples. Rings of full-depth articular cartilage slices were derived from human donors undergoing knee replacement for osteoarthritis and a 3 mm core of a collagen/glycosaminoglycan biomimetic scaffold (Tigenix, UK) inserted to create the EVM. Adult osteoarthritis chondrocytes were seeded into the scaffold and cultures maintained for up to 30 days. Ex vivo models were stable throughout experiments, and cells remained viable. Chondrocytes seeded into the EVM attached throughout the scaffold and in contact with the cartilage explants. Cell migration and deposition of extracellular matrix proteins in the scaffold was enhanced by growth factors particularly if the scaffold was preloaded with growth factors. This study demonstrates that the EVM represents a suitable model that has potential for testing a range of therapeutic parameters such as numbers/types of cell, growth factors or therapeutic drugs before progressing to costly pre-clinical trials. © 2015 The Authors.

Abstract
BACKGROUND The number of breast cancer survivors in our ageing population continues to rise. Policy makers internationally are seeking to identify alternatives to follow-up care in an acute setting. AIMS The National Cancer Control Programme set out to develop a new policy for long-term follow-up of breast cancer survivors in Ireland. METHODS Policy development was informed by analysis of current attendances at breast surgical clinics for routine follow-up, extraction of the necessary components of follow-up from international guidelines and focus group research with Irish patients. RESULTS Intensive follow-up investigations, other than mammography, do not confer additional survival benefit or improved quality of life. Provision of routine follow-up care of breast cancer survivors by GPs has been shown to be equivalent to follow-up by specialist clinics, in terms of clinical outcomes, patient quality of life and patient satisfaction. In Ireland, routine follow-up accounted for 15.4% (95% CI: 13.8-17.0%) of clinic appointments. A third were at least 5 years post-operative. Women highlighted issues such as attachment to specialist services, importance of communication and need for clarity as to where responsibility of care lies. Reassurance, confidence in the primary care practitioner, and coordination of multiple appointments were also identified as important issues. CONCLUSION A significant proportion of breast cancer survivors attending hospital surgical clinics for long-term follow-up could be safely discharged at 5 years, with the hospital maintaining responsibility for annual mammography. Successful implementation will depend on informed patients, clinicians' acceptance and communication between primary and secondary care.

Abstract
A community oncology nursing programme was developed in Ireland between the hospital and community health services for patients receiving systemic cancer therapy, in response to a service need. A robust evaluation of the pilot programme was undertaken, which found that defined clinical procedures traditionally undertaken in hospitals were safely undertaken in the patient's home with no adverse effects. There was a dramatic decrease in hospital attendances for these defined clinical procedures, and hospital capacity was consequently freed up. Patients valued having aspects of their care delivered at home and reported that it improved their quality of life, including reduced hospital visits and travel time. Community nurses expanded their scope of practice and became partners with oncology day-ward nurses in caring for these patients. Community nurses developed the competence and confidence to safely deliver cancer care in the community. This initiative shows that defined elements of acute cancer care can be safely delivered in the community so long as the training and support are provided. The findings and recommendations of the evaluation resulted in university accreditation and approval for national roll-out of the programme. Integration of services between primary and secondary care is a key priority. This innovative programme is a good example of shared integrated care that benefits both patients and health-care providers.

Abstract
Alcohol consumption is causally related to cancer of the upper aero-digestive tract, liver, colon, rectum, female breast and pancreas. The dose response relationship varies for each site. We calculated Ireland's cancer incidence and mortality attributable to alcohol over a 10-year period. Between 2001 and 2010, 4,585 (4.7%) male and 4,593 (4.2%) female invasive cancer diagnoses were attributable to alcohol. The greatest risk was for the upper aero-digestive tract where 2,961 (52.9%) of these cancers in males and 866 (35.2%) in females were attributable to alcohol. Between 2001 and 2010, 2,823 (6.7%) of male cancer deaths and 1,700 (4.6%) of female cancer deaths were attributable to alcohol. Every year approximately 900 new cancers and 500 cancer deaths are attributable to alcohol. Alcohol is a major cause of cancer after smoking, obesity and physical inactivity. Public awareness of risk must improve. Over half of alcohol related cancers are preventable by adhering to Department of Health alcohol consumption guidelines.

Abstract
BACKGROUND Retention in treatment is a key indicator of methadone treatment success. The study aims to identify factors that are associated with retention. OBJECTIVES To determine retention in treatment at 12 months for Irish opiate users in methadone substitution treatment and to indicate factors that increase the likelihood of retention. METHODS National cohort study of randomly selected opiate users commencing methadone treatment in 1999, 2001, and 2003 (n = 1269). RESULTS Sixty-one percent of patients attending methadone treatment remained in continuous treatment for more than 1 year. Retention in treatment at 12 months was associated with age, gender, facility type, and methadone dose. Age and gender were no longer significant when adjusted for other variables in the model. Those who attended a specialist site were twice as likely to leave methadone treatment within 12 months compared with those who attended a primary care physician. The most important predictor of retention in treatment was methadone dose. Those who received <60 mg of methadone were three times more likely to leave treatment. CONCLUSION Retention in methadone treatment is high in Ireland in a variety of settings. The main factors influencing retention in methadone treatment was an adequate methadone dose and access to a range of treatment settings including from primary care physicians. SCIENTIFIC SIGNIFICANCE Providing an adequate dose of methadone during treatment will increase the likelihood of treatment retention. Methadone treatment by the primary care physician is a successful method of retaining opioid users in treatment.

Abstract
Hepatitis C became statutorily notifiable in Ireland on 1 January 2004. Prior to 2004, only hepatitis A and hepatitis B were notifiable as distinct types of hepatitis. A third category notifiable under the Infectious Diseases Regulations 1981 was "viral hepatitis unspecified". The majority of cases notified under this heading were thought to be due to infection with hepatitis C Virus (HCV). Between January 1 2004 and December 31 2005, the Department of Public Health HSE Eastern Region, received notification of 2,014 cases of HCV infection (2004, 941 cases, 2005 1,073 cases). This report outlines basic demographic details on cases notified and comments on missing data. Peak age band at notification for males and females is in the 25-29 year old age group where 538 (26.7%) were notified. Thirty cases notified (1.5%) were under 15 years of age. Drug misuse has been confirmed as a risk factor for 1247 (61.9%) of cases notified, and may be a risk factor in a large percentage of the reminder where risk factor data are unknown. Problems with completeness of notification have been identified. Enhanced surveillance of all hepatitis C infections is a prerequisite for future service planning.

Abstract
The aim of this study was to develop a hypothesis to explain the link between HIV prevalence and area of residence. The study was conducted in two parts using two existing data sources. In Part 1, the bloodborne viral test status and test results of a sample of clients attending treatment in December 2001 in two areas of Dublin, an inner city area (Dublin 8) and a suburban area (Dublin 24), were extracted from the Bloodborne Viral Status Dataset created by Grogan. In Part 2 the characteristics of heroin users seeking treatment for the first time at treatment services in their respective areas of residence, Dublin 8 or Dublin 24, between 1997 and 2000 were examined, using data from the National Drug Treatment Reporting System. A higher proportion of heroin users in Dublin 8 had HIV and hepatitis C than did their counterparts in Dublin 24. The analysis suggests that heroin users in Dublin 8 were more likely both to have ever used cocaine and to have used heroin daily, than were those who lived in Dublin 24. Also, a higher proportion of injectors living in Dublin 8 used heroin and cocaine concurrently than did their counterparts in Dublin 24. In both samples, heroin users who lived in Dublin 8 were older than those who lived in Dublin 24. The findings led to a hypothesis:'The risk of acquiring HIV is associated with area of residence and may be linked to cocaine use.

Abstract
In May 2000, public health authorities in Dublin, Ireland, identified a cluster of unexplained severe illness among injecting drug users (IDUs). Similar clusters were also reported in Scotland and England. Concurrent investigations were undertaken to identify the aetiology and source of the illnesses. In Dublin, 22 IDUs were identified with injection-site inflammation resulting in hospitalization or death; eight (36%) died. Common clinical findings among patients with severe systemic symptoms included leukaemoid reaction and cardiogenic shock. Seventeen (77%) patients reported injecting heroin intramuscularly in the 2 weeks before illness. Of 11 patients with adequate specimens available for testing, two (18%) were positive by 16S rDNA PCR for Clostridium novyi. Clinical and laboratory findings suggested that histotoxic Clostridia caused a subset of infections in these related clusters. Empiric treatment for infections among IDUs was optimized for anaerobic organisms, and outreach led to increased enrolment in methadone treatment in Dublin. Many unique legal, medical, and public health challenges were encountered during the investigation of this outbreak.

Abstract
In Locusta migratoria, activation of phenoloxidase in the haemolymph in response to injection of laminarin is age-dependent: being absent in fifth instar nymphs and newly emerged adults, and only becoming evident four days after the final moult. This pattern of change in phenoloxidase activation correlates with the pattern of change in the concentration of apolipophorin-III (apoLp-III) in the haemolymph. Injection of a conspecific adipokinetic hormone (Lom-AKH-I) has no effect on the phenoloxidase response in nymphs or newly emerged adults but, in adults older than four days, co-injection of the hormone with laminarin prolongs the activation of phenoloxidase in the haemolymph: a similar enhancement of the response to laminarin is observed in locusts that have been starved for 48 h but not injected with AKH-I. During most of the fifth stadium, injection of laminarin results in a decrease in the level of prophenoloxidase in the haemolymph; an effect that is not observed in adults of any age. Marked changes in the concentration of apoLp-III, and the formation of LDLp in the haemolymph, are observed after injection of laminarin (or LPS) and these are remarkably similar, at least qualitatively, to those that occur after injection of AKH-I. The involvement of lipophorins in the activation of locust prophenoloxidase in response to immunogens is discussed.

Abstract
OBJECTIVES Analysis of a referral population of patients with choroid plexus cysts (CPCs) was performed to compare an average risk method of counseling to an individualized risk method. METHODS A total of 395 patients referred to a Prenatal Diagnosis Center were included, of whom 341 had isolated CPCs and 54 had associated ultrasound abnormalities. For isolated CPCs, an average risk of 1/150 for aneuploidy was compared to an individualized risk assessment [prior risk as determined by maternal age or serum screening multiplied by the likelihood ratio established by Gupta et al. (1997)]. Accuracy, cost, and procedure-related losses were assessed. RESULTS Both methods resulted in 100% sensitivity. The individualized method resulted in greater specificity, decreased costs, and (theoretically) fewer procedure-related pregnancy losses. CONCLUSIONS An individualized risk method of counseling utilizing the likelihood ratios established by Gupta et al. (1997) was superior to an average risk method for assessing trisomy 18 risk in the setting of CPC detected in mid-trimester.

Abstract
Neurotrophin (NT)-3 is expressed in the neuronal target tissue of the developing rat cochlea and has been shown to promote the survival and neurite outgrowth of spiral ganglion (SG) neurons, suggesting a role for this protein during the innervation of the organ of Corti. In other neurons, NT-3 can mediate neuritogenesis and survival via a number of intracellular signal pathways. To date, the intracellular transduction pathways involved in the mediation of NT-3 effects have not been investigated in SG neurons. To determine whether the activities of NT-3 on SG neurons are dependent on the activation of mitogen-activated protein kinase kinases (MEK)/extracellular-signal-regulated kinases (ERK), Ras, and/or p38, SG explants from postnatal-day 4 rats were cultured with NT-3 and increasing concentrations of the MEK inhibitor U0126, the Ras farnesyl-transferase inhibitor (FTI)-277, and the p38 inhibitor SB203580. After fixation and immunocytochemical labeling, neurite growth was evaluated. A dose-dependent decrease of the effects of NT-3 on length and number of processes was observed in the U0126- and FTI-277-treated SG neurons. In contrast, SB203580 had no significant effect on NT-3-mediated stimulation of neurite growth, in terms of either number or length. The results suggest that NT-3 effects on SG neurons are mediated primarily by the Ras/MEK/ERK signaling pathway.

Abstract
The influence of laminin-1 (LN) and tenascin-C (TN), extracellular matrix molecules expressed spatially and temporally along the neural growth route from spiral ganglion (SG) neurons to the cochlear sensory cells, was evaluated in cultured SG explants from postnatal day 4 rats. Increasing concentrations of LN resulted in a strong, dose-dependent increase in the length of neurites and in a higher number of neural processes, while varying TN concentrations had relatively minor effects on both parameters. The results suggest differential receptor activation by LN and TN. When explants grown on LN were treated with Kistrin, an inhibitor of the alphavbeta3 integrin, the LN-induced increase in neurite length was reduced in a dose-dependent manner. However, the number of extending neurites was not affected, indicating that different receptors mediate this response, perhaps by increasing neuronal survival.

Abstract
AIMS Identification of characteristics and trends over time in young injecting drug users at first attendance at needle exchange. DESIGN Retrospective cross-sectional survey of routinely collected data. SETTING Dublin needle exchange programme which consists of 11 sites in the greater Dublin area. PARTICIPANTS First-time attenders (n = 1224) at the needle exchange from 1990 to 1997, between the ages of 15 and 19. MEASUREMENT Factors associated with a likelihood of needle sharing and condom use were tested using logistic regression. FINDINGS Increases in both the number and proportion of young injectors, particularly young female injectors, have occurred over the 8 years. Forty-eight per cent of the young injectors were injecting for less than 1 year. Needle sharing prevalence in the year previous to first attendance was 39% and condom use was 61%. The proportion of females not using a condom during sexual relationships was significantly higher than males. Very few of the young attenders had received any treatment for drug dependence. CONCLUSIONS After the first year of injecting drug use the likelihood of needle sharing increased and we recommend that interventions occur early on and are targeted to the needs of young injecting drug users, in particular young females. It is essential that services are accessible to the young injecting drug user and that barriers to contact with services are minimized or eliminated. Some high-risk behaviours are occurring in the context of the sexual relationship and this should be taken into account when designing prevention programmes, especially for young females.

Abstract
AIMS This was a pilot study of the use of a clinical pharmacist as a therapeutics adviser (academic detailer) to modify antibiotic prescribing by general practitioners. METHODS Following a visit by the adviser (March-May), 112 general practitioners were recruited and randomised to control or active groups. A panel of experts prepared a best practice chart of recommended drugs for upper and lower respiratory tract infections, otitis media and urinary tract infections. The adviser made a 10-15 min visit to each prescriber in the active group (June-July), gave them the chart and discussed its recommendations briefly. Doctors in the control group were not visited nor given the chart. Prescription numbers for all prescribers were obtained from the Commonwealth Health Insurance Commission for the pre(March-May) and postdetailing (August-September) periods using a three month lag time for data collection. Data for total numbers of prescriptions and for selected individual antibiotics used in these two periods were analysed using nonparametric statistics. RESULTS Prescribing patterns were similar for the control and active groups in the predetailing period. For both groups, there were significant (P<0.03) increases (45% for control and 40% for active) in total number of antibiotic prescriptions in the post compared with the predetailing period. This trend was anticipated on the basis of the winter seasonal increase in respiratory infections. In line with the chart recommendations for first-line treatment, doctors in the active group prescribed significantly more amoxycillin (P<0.02) and doxycycline (P<0.001) in the post vs predetailing periods. By contrast, doctors in the control group prescribed significantly more cefaclor (P<0.03) and roxithromycin (P<0.03), drugs that were not recommended. The total cost of antibiotics prescribed by doctors in the control group increased by 48% ($37 150) from the preto postdetailing periods. In the same time period, the costs for the active group increased by only 35% ($21 020). CONCLUSIONS We conclude that the academic detailing process was successful in modifying prescribing patterns and that it also decreased prescription numbers and costs. Application of the scheme on a nationwide basis could not only improve prescriber choice of the most appropriate antibiotic but also result in a significant saving of health care dollars.

Abstract
In many adult epithelia, e.g., epidermis or intestine, adhesion of epithelial cells to basement membrane requires the integrin alpha6 beta4 and laminin-5 (Ln-5). In the absence of one or the other, extensive blistering and exfoliation occur. While alpha6 beta4 was reported to be a receptor for Ln-5, this interaction is poorly understood. We characterize complexes between alpha6 beta4 and Ln-5 in cell-free preparations of extracellular matrix (ECM) from the epithelial cell line, 804G. By microsequencing, Ln-5 and alpha6 beta4 were the major proteins in this ECM and were likely engaged in receptor/ligand complexes because, by immunofluorescence, alpha6 beta4 was colocalized with Ln-5 both in cell monolayers and in cell-free ECM preparations, but they disappeared after preincubation of the monolayers with alpha6 beta4 or Ln-5 function-blocking antibodies. The alpha6 beta4/Ln-5 complexes were resistant to dissociation by extreme pH, urea, chaotropes, eDTA, non-ionic detergents, and b-mercaptoethanol. They were only dissociated by strong anionic detergents, e.g., 1% SDS, suggesting receptor/ligand interactions based on high affinity or avidity. We propose that these alpha6 beta4/Ln-5 complexes may provide links between plasma membrane and basement membrane that resist mechanical stress and support epithelial integrity.

Abstract
PURPOSE To describe the clinical findings of an autosomal dominant macular dystrophy in a family of Mayan Indian ancestry in Belize, Central America, and to determine its molecular genetic relationship with the original North Carolinian family. METHODS We performed comprehensive ophthalmic examinations on 56 members of a single family living in Chicago, Illinois, and Belize, Central America. Fundus photography and fluorescein angiography were performed on 17 affected subjects and six affected family members were serially examined over a 12-year period. Blood was collected from 26 individuals, and DNA was extracted for genotyping. Two-point linkage, multipoint linkage, and haplotype analysis was performed. RESULTS In 17 affected individuals, the clinical features were consistent with the diagnosis of North Carolina macular dystrophy. Multipoint linkage analysis generated a peak lod score of 5.6 in the MCDR1 region. The haplotype associated with the disease was, however, different from that of the original North Carolinian family. CONCLUSIONS This family has an autosomal dominant macular dystrophy that is clinically indistinguishable from North Carolina macular dystrophy (MCDR1). Our findings indicate that the mutated gene in this Belizean family maps precisely to the same region as that of the North Carolina macular dystrophy (MCDR1) locus. This study provides evidence that MCDR1 occurs in various ethnic groups and that there is no evidence of genetic heterogeneity.

Abstract
Schedule induced polydipsia, urination and defecation were examined in rats that received training on a fixed interval 2 min schedule of food reinforcement. In Phase I of the experiment, animals received peripheral injections of captopril (an angiotensin conversion enzyme blocker, 0.5 or 50 mg/kg), or equivalent volumes of 0.9% saline. The results showed that low doses of captopril (0.5 mg/kg) significantly increased both operant responding and the adjunctive behaviors. High peripheral doses of captopril significantly reduced responding and schedule induced behavior. In Phase II of the experiment, animals received either low peripheral doses of captopril (sc 0.5 mg/kg), or low doses that were coupled with central injections (i.e., 0.12 mg icv + 0.5 mg/kg sc). As observed in Phase I, low peripheral doses of captopril enhanced behavior, but the enhancement effect was eliminated with low (0.12 mg) central administration. The overall results are consistent with past research examining captopril effects on non-operant, meal-induced drinking. Yet since captopril affected operant responding and adjunctive behaviors similarly, the findings suggest that angiotensin plays a common role in the motivational processes that precede and follow the arrival of food.

Abstract
PURPOSE To determine if a family in France, which manifests an autosomal dominant macular dystrophy, has North Carolina macular dystrophy (MCDR1) and to determine its possible molecular genetic relationship with the original North Carolina family. METHODS A family from Northern France with a macular dystrophy underwent comprehensive ophthalmic examinations and were ascertained for genetic studies. Blood collection and examinations were performed on 38 individuals. Fundus photographs with a hand held KOWA camera were obtained on affected subjects. DNA was extracted and genotyping performed using new microsatellite genetic markers, which have recently been found in the MCDR1 (North Carolina macular dystrophy) region. Standard two - point linkage and haplotype analysis was performed. RESULTS Eleven individuals were found with the clinical manifestations of North Carolina macular dystrophy. Two - point linkage analysis generated a maximum peak LOD score of 4.5 with a recombination of 0% between D6S1717 and the macular dystrophy locus in the French family. The haplotype associated with the disease is, however, different from that of the original North Carolina family. CONCLUSIONS These findings indicate that the macular dystrophy gene in this French family maps to the same region as that of North Carolina macular dystrophy (MCDR1) locus but that independent mutations are involved. The disease in the French family is clinically and genetically similar to North Carolina macular dystrophy. Therefore MCDR1 occurs in various ethnic groups, is present world-wide, and there remains no evidence of genetic heterogeneity for this clinically distinct form of macular degeneration.

Abstract
Three patients had exceptionally high seizure threshold, as determined by an empirical titration procedure. Initial seizure threshold was 896 mC in two of the patients. The third patient had an initial threshold of 336 mC that increased to 840 mC at the end of the course of electroconvulsive therapy (ECT), and remained elevated during a second course of ECT. All three patients were elderly men with complicated medical histories and ongoing low-dose benzodiazepine use. Each patient had an excellent response to ECT delivered with a custom modified device, capable of delivering more than twice the charge of ECT devices presently commercially available in the United States. Implications for the administration of ECT in patients with exceptionally high seizure threshold and the limitations of current device output are discussed.

Abstract
PURPOSE Recently several autosomal dominant corneal stromal dystrophies have been mapped to chromosome 5q. Therefore, we tested whether Reis-Bücklers' corneal dystrophy, an autosomal dominant trait, was also linked to the same region. METHODS Five generations of a single family with Reis-Bücklers' corneal dystrophy were ascertained. Twenty-two family members were examined, and 11 were found to be affected. Blood was obtained for genetic linkage analysis. RESULTS Several genetic markers on chromosome 5q were strongly suggestive of linkage or confirmed linkage (LOD score > 3.0). Multipoint analysis generated a maximum LOD score of 4.25 between D5S414 and IL-9. CONCLUSIONS Reis-Bücklers', lattice type 1, Avillino, and granular corneal dystrophies all map to the same genetic locus. This suggests that one of the following might be true: (1) that a corneal gene family exists in this region; (2) that these corneal dystrophies represent allelic heterogeneity (that is, different mutations within the same gene manifest as different phenotypes); or (3) that these are all the same disease.

Abstract
PURPOSE We studied a single, large family with autosomal dominant cone degeneration in order to map the disease-causing gene. METHODS Seventy-three individuals in this family were examined, and 34 were found to be affected. Blood samples from 34 affected and unaffected family members were obtained for DNA analysis and linkage mapping. Fifty-three genetic markers were analyzed in this family by using short tandem repeat markers. These markers were primarily in candidate genomic regions. RESULTS Marker D17S796 generated a significantly positive LOD score of 4.21 (theta = .04; 10,000:1 odds in favor of linkage). Marker D17S513 gave a significant LOD score of 3.1 (theta = .096; 1,000:1 odds in favor of linkage). Other markers in the region generated suggestive findings, such as D17S786, with a LOD score of 2.7, and D17S945, with a LOD score of 2.41. CONCLUSIONS Our results indicate that a genetic defect that causes autosomal dominant cone degeneration is located on chromosome 17p in the region of recoverin. Recoverin, a retinal expressed gene, is an appealing candidate for this disease.

Abstract
OBJECTIVE To determine the safety of a freestanding surgical unit for assisted reproductive technology (ART), using the rate of unplanned admissions to a hospital within 24 hours of surgery. DESIGN Prospective. SETTING A freestanding surgical unit within a medical office building. PATIENTS A mixture of private and university-referred patients undergoing 6,776 ART surgical procedures. MAIN OUTCOME MEASURES Patients admitted during the first 24 hours of surgery were recorded and hospital progress was monitored for invasive procedures, treatments, time of discharge, and residual complications. Variables tabulated included age, fertility diagnosis, ART procedure, E2 level, number of follicles by ultrasound, previous surgery, and type of anesthesia. RESULTS There were 11 hospital admissions (0.16%). Four patients required surgery: one laparoscopy and three laparotomies. Admissions after vaginal oocyte retrieval were no different from those after GIFT via laparoscopy, 0.16% versus 0.18%, respectively. The number of admissions after monitored anesthesia care was higher than expected compared with general anesthesia. Profiles of hospitalized patients showed no apparent differences from the nonhospitalized patients. CONCLUSIONS Surgical procedures for ART performed in a freestanding surgical unit can be performed safely with a low hospitalization rate and minimal morbidity.

Abstract
Blepharophimosis syndrome (BPES, blepharophimosis eyelid syndrome) is a distinctive congenital eyelid malformation which can occur sporadically or be inherited in an autosomal dominant fashion. Previous reports have described associated cytogenetic abnormalities on chromosome 3q. We have ascertained and sampled two BPES families with apparent autosomal dominant inheritance and have tested for linkage with 17 polymorphic markers on 3q. Multipoint analysis generated a maximum LOD score of 3.23 using the markers RHO, ACPP and D3S1238. No evidence of genetic heterogeneity was observed. These studies provide the first non-cytogenetic evidence that a defective gene responsible for BPES is located on 3q22.

Abstract
Although classified as a disorder of impulse control, trichotillomania (hair pulling) may have some phenomenological overlap with obsessive-compulsive disorder (OCD). The question arises as to whether trichotillomania is best conceptualized as a disorder characterized by impulsivity or compulsivity. Impulsive and compulsive symptoms and traits were compared in 43 patients who presented for treatment of trichotillomania, OCD or impulsive personality disorder. Trichotillomania patients had significantly lower scores of obsessive-compulsive symptoms than OCD patients, and significantly higher impulsiveness scores than this group. Measures of aggression did not differ significantly between groups.

Abstract
This pilot study evaluated neuropsychological dysfunction in obsessive-compulsive disorder (OCD) and Parkinson's disease (PD). Both OCD and PD patients had impairment on visuoconstructional tasks but not on tasks of immediate memory and focused attention, suggesting common selective deficits in these two disorders with basal ganglia involvement.

Abstract
BACKGROUND Fluoxetine, a selective serotonin reuptake blocker, is an antidepressant medication that has also been shown in open clinical trials and one controlled trial to be effective in the treatment of obsessive compulsive disorder (OCD). OCD is often complicated by depression, and depressive symptoms may interfere with response to both pharmacologic and behavioral treatments. METHOD We describe pilot data from 10 outpatients who met DSM-III-R criteria for OCD in whom the possibility of a depressive reaction or lack of antidepressant response occurred during an open trial of fluoxetine. RESULTS Rapid increase in fluoxetine dose to high doses was associated with depressive symptoms in 6 patients. In 8 patients, improvement in depression was associated with addition of a tricyclic antidepressant to fluoxetine treatment. In 5 patients, both OCD and depressive symptoms improved when the patient was switched to the partially selective serotonin reuptake blocker clomipramine. CONCLUSION This paper serves to alert clinicians to the possibility of a depressive reaction, or lack of antidepressant response, to fluoxetine in OCD patients. This possibility can only be resolved scientifically by adequately controlled experimental trials. If depression occurs, combined fluoxetine and tricyclic treatment, or a switch to a partially selective serotonin reuptake inhibitor, may be helpful. Special considerations and side effects of combined fluoxetine-tricyclic treatment are described.

Abstract
This study provides data on changes in the functional status of older patients that are associated with acute hospitalization. Seventy-one patients over the age of 74 admitted to the medical service of Stanford University Hospital between February and May 1987 received functional assessments covering seven domains: mobility, transfer, toileting, incontinence, feeding, grooming, and mental status. Assessments were obtained by report from the patient's caregiver (or the patient when he or she lived alone) for 2 weeks before admission; from the patient's nurse on day 2 of hospitalization and on the day before discharge; and again from the caregiver (or patient) 1 week after discharge. The sample had a mean age of 84, covered 37 Diagnostic Related Groups, and had a median length of stay of 8 days. Between baseline and day 2, statistically significant deteriorations occurred for the overall functional score and for the individual scores for mobility, transfer, toileting, feeding, and grooming. None of these scores improved significantly by discharge. In the case of mobility, 65% of the patients experienced a decline in score between baseline and day 2. Between day 2 and discharge, 67% showed no improvement, and another 10% deteriorated further. These data suggest that older patients may experience a burden of new and worsened functional impairment during hospitalization that improves at a much slower rate than the acute illness. An awareness of delayed functional recovery should influence discharge planning for older patients. Greater efforts to prevent functional decline in the hospitalized older patient may be warranted.

Abstract
A 5-day patient education program, taught on an outpatient basis, was evaluated to determine its effect on metabolic control as reflected by glycosylated hemoglobin test values. A quasi-experimental design was used, consisting of a pretest, a posttest, and a follow-up assessment made approximately 6 months after the posttest. The 72 experimental and 324 comparison subjects all had insulin-dependent diabetes mellitus (IDDM), were between 14 and 78 years of age, and had a duration of diabetes ranging from 1 to 20 years. The experimental group demonstrated a statistically significant improvement in Hb A1 values from pre- to posttest and sustained these posttest levels upon follow-up, although not at statistically significant levels. The comparison group showed no pre- to posttest difference, but demonstrated an improvement from posttest to follow-up assessment.

65Copper absorption by women fed intrinsically and extrinsically labeled goose meat, goose liver, peanut butter and sunflower butter. J Nutr 1988; 118:1522-8.

Abstract
Absorption of stable 65Cu incorporated intrinsically or extrinsically into foods was studied in women fed a diet marginal in Cu content. Isotopic enrichment was 73.1 +/- 1.0 atom percent 65Cu in goose breast meat, 74.9 +/- 0.5 atom percent in goose liver, and 55-69.5 atom percent in two crops of peanuts. Seven women were fed a basal diet containing 1.25 mg Cu/d. At 4-wk intervals, they were fed test meals over a 3-d period; each set of meals contained one of the labeled test foods in amounts with similar copper content. Absorption of 65Cu from intrinsically labeled liver was (mean +/- SD) 65 +/- 4%; extrinsic liver, 65 +/- 10%; E/I = 1.00 +/- 0.16. 65Cu absorption from intrinsically labeled goose breast meat was 54 +/- 6%; extrinsic meat, 52 +/- 10%; E/I = 0.97 +/- 0.18. 65Cu absorption from intrinsically labeled peanut butter was 58 +/- 15%; extrinsic peanut butter, 54 +/- 10%; E/I = 0.93 +/- 0.11. 65Cu absorption from extrinsically labeled sunflower butter was 50 +/- 2%. There were no differences in absorption of intrinsic and extrinsic Cu from these foods. Absorption of Cu was significantly higher from goose liver than from goose meat or sunflower butter (P less than 0.05). With a dietary intake of 1.25 +/- 0.20 mg Cu/d, Cu balance, exclusive of surface losses, was essentially zero (0.01 +/- 0.13 mg/d) in the seven subjects.
