[Hospital hygiene and antibiotherapy counselling: an operational dual solution against the spreading of multiresistant bacteria].

OBJECTIVES: The authors had for aim to show that preventing the diffusion of multidrug-resistant organism (MRO) is possible thanks to the coordination of recommended preventive actions and the implementation of a sensible anti-infective prescription policy. They also wanted to highlight the role played by the nursing care staff in enforcing recommendations. METHOD: We compared the results of two health care facilities having both implemented the same strategy aimed at preventing cross-transmission and prescribing anti-infective drugs. RESULTS: Audits reported a very variable enforcement of recommendations. The results obtained from microbiological monitoring confirmed the essential impact of protocol enactment by every team, on the control of MRO diffusion. The antibiotherapy specialist has a key role in the suggested strategy, allowing a significant decrease in the number of anti-infective prescriptions and a more rational use. CONCLUSION: The collaboration of a hygiene specialist with an antibiotherapy specialist has proved operational in the fight against MRO diffusion, as long as the competences of both specialists are acknowledged and their cross-disciplinary activities accepted. For the entire staff, enacting a corporate culture is a crucial asset.

Discordance between physician and adolescent assessments of adherence to treatment: influence of HbA1c level. The PEDIAB Collaborative Group.

OBJECTIVE: To compare the subjective assessments (perceptions) of physicians and adolescent diabetic patients on the adolescents' adherence to treatment and to test the hypothesis that the HbA1c level influences physicians' perceptions. RESEARCH DESIGN AND METHODS: In a multicenter cross-sectional survey, 143 adolescents with diabetes (mean age 14.6 years) auto-assessed, while their pediatricians independently assessed, the level of adherence to treatment on a four-point scale. Scores of adherence given by a validated scale and metabolic control (HbA1c) were compared according to those assessments. RESULTS: Agreement between the adherence perceptions from adolescents and physicians was low (kappa = 0.23), and adolescents scored significantly higher (P < 0.001). Mean adherence score to diabetes treatment was significantly higher when the adolescents' perception of their self-care behaviors was good than when it was poor (P = 0.01), but did not significantly differ according to physicians' perception. Mean HbA1c level was significantly lower when the self-care behavior perception was good than when it was poor, both for the adolescents (P = 0.02) and for the physicians (P < 0.001). Multivariate analyses showed that only the adherence scale score was significantly associated with the adolescents' perception (P = 0.015), whereas only HbA1c level was significantly associated with the physicians' perception (P = 0.0008). CONCLUSIONS: By identifying the possible discrepancy between their own assessment of adherence and that of adolescents, and by avoiding the systematic attribution of poor metabolic control to poor adherence, physicians could generate a more confident and collaborative relationship with diabetic adolescents and therefore facilitate adolescents' self-management.

Cross-cultural surveys of adolescent health and behavior: progress and problems.

Adolescent health surveys administered in different countries or regions often are described as cross-cultural. Although most include youth of different ethnic and cultural groups, few attempt to define these constructs or to collect data that allow their characterization. This paper explores four challenges shared by large-scale surveys of adolescent health-related behaviors and beliefs. First, adolescent health investigators have used the terms culture and ethnicity loosely. The growing interest in contextual analysis demands standardization of the definitions as they apply to adolescents, followed by correct usage of the terms. Hypotheses regarding the associations between race, ethnicity, culture, health-related behaviors, and health outcomes should be clearly stated and incorporated into conceptual models. Second, cross-cultural analyses are interpretable only when the study designs and sampling methods provide adequate representation of cultural and ethnic minorities and when the survey items allow differentiation of factors related to race, ethnicity, culture, and socioeconomic factors. Third, cross-cultural research may expose traditions, beliefs, and behaviors that are supported by one population yet criticized by another. Investigators must recognize their own personal biases and must work collaboratively to analyze and interpret their data correctly. Fourth, generalizations about cultural/ethnic comparisons can evoke powerful emotional reactions. Interpretation and dissemination of research findings should be done sensitively and with the help of experts from the cultural/ethnic groups that have been studied.

Building true collaborations. A senior support network illustrates a successful partnership of healthcare and social service providers.

The relationship between Catholic Social Services (CSS) of the Diocese of Scranton and Mercy Health Partners--Northeast Region, which joined forces last year to develop a senior support network for residents of Wilkes-Barre and the Borough of Kingston, PA, illustrates how collaboration grows out of cooperation and coordination of services. The network is a project of the Neighborhood-Based Senior Care National Initiative, which works to develop collaborations between Catholic health systems and Catholic Charities agencies to help poor communities meet the needs of aging persons. Barriers to successful collaboration may stem from cultural misunderstandings, differences in organizational stability and decision-making processes, attitudes toward money, and even professional vocabularies. Organizations that trust and respect each other can overcome these barriers. The Wilkes-Barre project began simply, but its success established a pattern of cooperation between CSS and Mercy Health Partners, which led to further coordination of referral programs, development of community health profiles, and cross-organizational training. After nine months on the Wilkes-Barre project, CSS and Mercy Health Partners are now developing a Program of All-Inclusive Care for the Elderly (PACE). Effective collaboration between healthcare providers and social service agencies is a long, sometimes difficult, process that requires organizational commitments of time and resources. Organizations must not yield to the temptation to take shortcuts to achieve short-term gains.

A comparison of collaborative and individual everyday problem solving in younger and older adults.

To understand the conditions under which age differences in everyday problem-solving performance occur, this study investigated individual and collaborative problem solving. Younger (24 females, 24 males; M age = 19.98, SD = 1.43) and older adults (25 females, 24 males; M age = 71.14, SD = 6.65) worked either alone or with a same-sex friend to plan a cross-country trip to attend a wedding. Age differences favoring younger adults were found on three of eight performance measures: two component completion accuracy variables (i.e., city completion, Mt. Rushmore completion) and a composite variable that assessed overall performance. Younger adults also completed the task faster than did older adults. Collaborators out-performed individuals on the composite measure of overall performance and frequency of planning errors. Females committed more planning errors than males did. Younger and older adults' performances were predicted by different variables; however, basic abilities were not consistently significant predictors of performance for either younger or older adults. The results of the study suggest that task characteristics may differentially influence older and younger adults' collaborative performance.

Effects of protein, monounsaturated fat, and carbohydrate intake on blood pressure and serum lipids: results of the OmniHeart randomized trial.

CONTEXT: Reduced intake of saturated fat is widely recommended for prevention of cardiovascular disease. The type of macronutrient that should replace saturated fat remains uncertain. OBJECTIVE: To compare the effects of 3 healthful diets, each with reduced saturated fat intake, on blood pressure and serum lipids. DESIGN, SETTING, AND PARTICIPANTS: Randomized, 3-period, crossover feeding study (April 2003 to June 2005) conducted in Baltimore, Md, and Boston, Mass. Participants were 164 adults with prehypertension or stage 1 hypertension. Each feeding period lasted 6 weeks and body weight was kept constant. INTERVENTIONS: A diet rich in carbohydrates; a diet rich in protein, about half from plant sources; and a diet rich in unsaturated fat, predominantly monounsaturated fat. MAIN OUTCOME MEASURES: Systolic blood pressure and low-density lipoprotein cholesterol. RESULTS: Blood pressure, low-density lipoprotein cholesterol, and estimated coronary heart disease risk were lower on each diet compared with baseline. Compared with the carbohydrate diet, the protein diet further decreased mean systolic blood pressure by 1.4 mm Hg (P = .002) and by 3.5 mm Hg (P = .006) among those with hypertension and decreased low-density lipoprotein cholesterol by 3.3 mg/dL (0.09 mmol/L; P = .01), high-density lipoprotein cholesterol by 1.3 mg/dL (0.03 mmol/L; P = .02), and triglycerides by 15.7 mg/dL (0.18 mmol/L; P<.001). Compared with the carbohydrate diet, the unsaturated fat diet decreased systolic blood pressure by 1.3 mm Hg (P = .005) and by 2.9 mm Hg among those with hypertension (P = .02), had no significant effect on low-density lipoprotein cholesterol, increased high-density lipoprotein cholesterol by 1.1 mg/dL (0.03 mmol/L; P = .03), and lowered triglycerides by 9.6 mg/dL (0.11 mmol/L; P = .02). Compared with the carbohydrate diet, estimated 10-year coronary heart disease risk was lower and similar on the protein and unsaturated fat diets. CONCLUSION: In the setting of a healthful diet, partial substitution of carbohydrate with either protein or monounsaturated fat can further lower blood pressure, improve lipid levels, and reduce estimated cardiovascular risk. Clinical Trials Registration ClinicalTrials.gov Identifier: NCT00051350.

National health accounts in developing countries: appropriate methods and recent applications.

Better information on the financing of the health sector is an essential basis for wise policy change in the area of health sector reform. Analysis of health care financing should begin with sound estimates of national health expenditure--total spending, the contributions to spending from different sources and the claims on spending by different uses of the funds. The member countries of the OECD have successfully established such comparative health expenditure accounts in terms of standardized definitions of the uses of funds and breakdowns by public and private sector sources. This has resulted in important research on health system differences which could explain variations in the level and composition of financing. The United States has developed a more detailed approach called National Health Accounts, which expands the OECD method into a more disaggregated 'sources and uses' matrix. In the developing countries, analysis of health expenditures has been much less systematic, despite several decades of calls by international researchers for more attention. This paper reviews previous work done in developing countries and proposes renewed attention to national health expenditures, adapting the recent experience of the United States. Because most developing countries have more pluralistic health financing structures than are found in most industrialized countries, an enhanced and adapted version of the 'sources and uses' matrix method is proposed. This method should be modified to address the relevant categories of expenditures prevalent in the developing countries. Examples of recent applications of such 'national health accounts' from the Philippines, Egypt, India, Mexico, Colombia and Zambia are presented. Experience to date suggests that development of sound estimates using this method in low and middle income countries is feasible and affordable. National health accounts estimates can significantly influence policy. They provide decision makers with a holistic picture of the health sector, showing the actual emphasis of spending and the roles of different payers. They also provide a consistent framework for modelling reforms and for monitoring the effects of changes in financing and provision. An easy to use software tool has been developed for training and data management. Regional networks of collaborating national groups are proposed as a first step in expanding use of the method and to gain both national and cross-national comparative benefits.

Recommendations for Life-Supporting First-Aid training of the lay public for disaster preparedness.

In catastrophic disasters such as major earthquakes in densely populated regions, effective Life-Supporting First-Aid (LSFA) and basic rescue can be administered to the injured by previously trained, uninjured survivors (co-victims). Administration of LSFA immediately after disaster strikes can add to the overall medical response and help to diminish the morbidity and mortality that result from these events. Widespread training of the lay public also may improve bystander responses in everyday emergencies. However, for this scheme to be effective, a significant percentage of the lay population must learn in eight basic steps of LSFA. These have been developed by the International Resuscitation Research Center in collaboration with the World Association for Emergency and Disaster Medicine, the City of Pittsburgh Department of Public Safety, and the American Red Cross (Pennsylvania chapter). They include: 1) scene survey; 2) airway control; 3) rescue breathing (mouth-to-mouth); 4) circulation (chest compressions; may be omitted for disasters, but should be retained for everyday bystander response); 5) abdominal thrusts for choking (may be omitted for disasters, but retained for everyday bystander response); 6) control of external bleeding; 7) positioning for shock; and 8) call for help.

Multi-level analysis of alcohol-related injury among emergency department patients: a cross-national study.

AIM: The aim of this analysis was to examine the average rate and variation of alcohol-related injury across emergency department (ED) studies, the effect of usual drinking on likelihood of alcohol-related injury, whether cross-study variation in rate of alcohol-related injury can be explained by between-study difference in usual consumption and whether social-cultural contextual variables help explain cross-study variations, after between-study difference in usual consumption has been controlled. DESIGN: Data were merged from the Emergency Room Collaborative Alcohol Analysis Project (ERCAAP) and the WHO Collaborative Study on Alcohol and Injuries, together representing 28 studies in 16 countries, and include 8423 (drinking) injury patients who arrived in the ED within 6 hours after injury. Alcohol-related injury was based, separately, on a positive blood alcohol concentration (BAC) and self-reported drinking within 6 hours prior to injury. A multi-level design and hierarchical generalized linear models were used for analysis in which patients were nested within studies. FINDINGS: Overall prevalence of alcohol-related injury was 24% and 29% for positive BAC and self-report, respectively. At the patient level, log-transformed alcohol consumption in the last 12 months was a significant predictor of alcohol-related injury. At the study level significant variation in rates of alcohol-related injury was observed; studies with higher overall average consumption reported a higher rate of alcohol-related injury. When volume was controlled, societies with higher detrimental drinking pattern and higher legal level for intoxication while driving were more likely to have an increased rate of alcohol-related injury. CONCLUSIONS: Alcohol-related injury varies across EDs and countries. While it is associated with an individual's usual alcohol consumption, it is also affected by a number of societal drinking characteristics including the aggregate volume of consumption, overall drinking pattern and legislative policies to control drinking and related harms.

Service provision among adult public dental service patients: baseline data from the Commonwealth Dental Health Program..

Patients using publicly funded dental care have been reported to have frequent emergency visits and extractions; however, reports have been based on data from a limited number of sites around Australia. The aims of this study were to provide baseline data at the beginning of the Commonwealth Dental Health Program to describe the service characteristics of patients receiving publicly funded dental care, and to analyse factors associated with extraction of teeth. In collaboration with state and territory government health departments, data were collected on patient characteristics, visit details and services received by a cross-sectional sample of adult patients receiving dental care in Queensland in October 1993, in New South Wales, Victoria, South Australia, Tasmania, the Australian Capital Territory and the Northern Territory from March to April 1994, and in Western Australia in October 1994. Data were available for 17,653 dental visits (89.4 per cent were dentate, 56.6 per cent were female, 69.1 per cent were from capital cities, and 38.0 per cent visited for an emergency). For dentate persons, logistic regression showed that factors associated with extractions were: age (< 30 years odds ratio (OR) = 1.28, reference 30+ years), sex (male OR = 1.37, reference (female), indigenous persons (indigenous OR = 2.56, reference nonindigenous), visit type (emergency OR = 4.70, reference nonemergency), and location (noncapital OR = 1.29, reference capital city). In publicly funded dental care, retention of teeth might be enhanced through changes in visit patterns, particularly for younger, male, indigenous and rural patients. Improved access for care is needed to achieve more desirable visit patterns, which would include: less emergency care and more planned care, shorter waiting times for nonemergency care, and fewer extractions.

Neurotransmitters and neurotrophins collaborate to influence brain development.

It is well recognized that the neurotrophin family of factors as well as neurotransmitters play critical roles in the ontogeny of the brain. Moreover, a growing literature suggests that these environmental signals do not operate individually, but interact in critical ways to enhance maturation. This review focuses on three brain systems where this collaboration is particularly evident: the cerebellum, the basal forebrain-hippocampus and locus coeruleus-hippocampus. The material presented indicates that cross-talk between neurotransmitters and neurotrophins may be a mechanism common to the development of multiple neuronal groups throughout the central nervous system. Moreover, this cross-talk appears to involve the interaction of both neuronal and glial cell populations.

Demographic and clinical characteristics of men with chronic prostatitis: the national institutes of health chronic prostatitis cohort study.

PURPOSE: We describe the study design of the National Institutes of Health Chronic Prostatitis Cohort (CPC) study characterizing men with chronic prostatitis/the chronic pelvic pain syndrome. MATERIALS AND METHODS: All 488 men screened into the CPC study before close of recruitment on August 22, 2001 were selected for analysis. The National Institutes of Health Chronic Prostatitis Symptom Index, including subscores, was used to measure symptoms. A comprehensive history, physical examination and demographic profile were obtained from each participant. Generalized Mantel-Haenszel procedures were used to investigate baseline associations between selected factors and symptoms. RESULTS: Chronic prostatitis/chronic pelvic pain syndrome is a chronic syndrome affecting men over a wide age range. The majority of CPC study participants are white, well educated and affluent. However, lower education, lower income and unemployment were associated with more severe symptoms. Patients most frequently reported pain in the perineum and tenderness in the prostate. The highest self-reported diseases were genitourinary (55%), allergies (53%), neurological (40%) and hematopoietic, lymphatic or infectious (40%). This disease has a significant negative impact on mental and physical domains of quality of life. Almost all patients (95%) reported antimicrobial drug use. Of these 488 participants 280 (57%) reported the previous or current use of 5 or more categories of prostatitis related treatments. CONCLUSIONS: Chronic prostatitis/chronic pelvic pain syndrome is a multifactorial problem affecting men of all ages and demographics. Patients with the chronic pelvic pain syndrome have dismal quality of life and many have benefited only minimally from empirical, goal directed therapy. Long-term followup of this cohort may answer important questions on the natural treated history of this syndrome.

Plasmodium falciparum parasite prevalence in East Africa: a review.

OBJECTIVES: Empirical data on malaria endemicity are rarely available for public domain use to guide effective malaria control. This paper describes the work carried in East Africa since 1997 as part of a pan-African collaboration to map the risk of malaria, Mapping Malaria Risk in Africa (MARA) aimed at redressing deficiency. DATA EXTRACTION: Studies of cross-sectional community estimates of Plasmodium falciparum prevalence among children aged 0-15 years were identified from a variety of sources including electronic searches of published material, manual review of pre-electronic peer reviewed journals and searches of libraries and archives in Kenya, Tanzania and Uganda. Each survey source, infection prevalence, date, longitude and latitude and survey characteristics were recorded. DATA SYNTHESIS: All data were subjected to a number of selection criteria including minimum sample sizes, samples randomly selected, community-based surveys, age ranges of sampled communities within 0-15 years, and surveys that were spatially unique. Of the 2,003 survey data points identified since 1907 in East Africa, only 503 were eligible for inclusion in the analysis dating from 1927 to 2003. The spatial plots of the data demonstrate the paucity of information on malaria prevalence from a number of densely populated areas and highlight the concentration of empirical data in concert with research centres in the sub-region. CONCLUSIONS: Models are required to define malaria risk in areas of East Africa where no empirical data are available so that limited resources can be better targeted to those in greatest need.

[Malignant lymphoma].

Malignant lymphoma is classified roughly into Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL) according to the biological characteristics. Malignant lymphoma in Japan has such characteristics as low incidence of HD, which is usually favorable in prognosis, and high incidence of NHLs, which have further distinctive features of less incidence of favorable follicular B cell lymphoma and of higher incidence of unfavorable diffuse T cell lymphoma including adult T cell leukemia/lymphoma (ATLL) in comparison with those in western countries. As a recent trend of progress in lymphoma study, the introduction of molecular diagnosis by means of gene rearrangement analysis of immunoglobulin and T cell antigen receptor has contributed diagnostically to a definitive determination of T and B cell lineage and cellular monoclonality in malignant lymphoma. On the other hand, remarkable progress has been made in the treatment of malignant lymphoma in recent years. After all, in HD even far advanced cases have been expected to be curable by the combination chemotherapy, for example, MOPP regimen in USA at the present time. Furthermore, in NHL even advanced cases with such aggressive lymphoma as diffuse large cell lymphoma of B cell type have also been able to survive for more than 10 years and may be curable with the frequency of more than 30% in several institutions. Nowadays, the treatment for malignant lymphoma has focussed on multidisciplinary cure-oriented therapy including chemotherapy and radiotherapy in a collaboration of surgical procedure and immunotherapeutic maneuvers. The recent chemotherapy regimen has been called "third generation" ones characterized by alternating non-cross resistant combination and frequent administration of intense drug dose. Furthermore, various biologics such as monoclonal antibodies, several BRMs including IFNs, IL-2 and TNF, and recombinant G-CSF and GM-CSF have been applied in lymphoma treatment to improve the efficacy of combination chemotherapy in new designs of clinical trials.

Tricyclic drugs for depression in children and adolescents.

BACKGROUND: There is a need to identify effective and safe treatments for depression in children and adolescents. While tricyclic drugs have proven effectiveness in the treatment of depression in adults, individual studies involving children and adolescent have been equivocal. OBJECTIVES: To examine whether orally administered tricyclic antidepressants are superior to placebo in the treatment of child and adolescent depression SEARCH STRATEGY: We searched the literature using CD ROM Silver Platter and On-Line MEDLINE (1966-1997) and Excerpta Medica (June 1974-1997) data bases. Terms used for the search were: the exploded terms child and depression; the Medical Subject Headings of antidepressant drugs, tricyclic and affective disorders; individual tricyclic drugs by name; names of well-known researchers in the field; and school phobia. We searched the trials database of the Cochrane Collaboration Depression, Anxiety and Neurosis Group. Abstracts in English (of English and non-English papers) were reviewed. Bibliographies of previously published reviews and papers describing original research were cross-checked. Current Contents was screened for recent publications. We contacted authors of abstracts describing "work in progress" identified in conference proceedings of the American Academy of Child and Adolescent Psychiatry to determine whether they held data which could be included in the meta-analysis. We have hand searched the Journal of the American Academy of Child and Adolescent Psychiatry to identify randomized controlled trials. SELECTION CRITERIA: Randomized controlled trials comparing the efficacy of orally administered tricyclic medication with placebo in depressed subjects aged 6-18 years. DATA COLLECTION AND ANALYSIS: Most studies reported multiple outcome measures including depression scales and clinical global impression scales. For each study the best available depression measure was taken as the index measure of depression outcome. Predetermined criteria were established to assist in the ranking of measures. Where authors reported categorical outcomes we calculated individual and pooled odds ratios for the odds of improvement in treated compared with control subjects. For continuous outcomes pooled effect sizes were calculated as the number of standard deviations by which the change in depression scores for the treatment group exceeded those for the control groups. MAIN RESULTS: Twelve studies fulfilled the criteria for inclusion in the review, eight from which dichotomous outcome data could be extracted, and eleven from which continuous outcome data could be extracted. Pooled odds ratios calculated from the dichotomous data indicated no advantage of treatment over placebo for children or adolescents (odds ratio = 0.83, 95% confidence interval 0.48 to 1.42). Effect size calculations from the continuous data suggested a statistically significant but small benefit of treatment over placebo in reducing symptoms for the aggregate sample (effect size = -0.38, 95% confidence interval -0.74 to -0.02) with subgroup analyses suggesting a larger benefit among adolescents (effect size = -0.59, 95% confidence interval -1.12 to -0.06), and no benefit among children (effect size = 0.15, 95% confidence interval -0.34 to 0.64). Treatment with a tricyclic antidepressant caused more vertigo (odds ratio = 8.47, 95% confidence interval 1.40 to 51.0), orthostatic hypotension (odds ratio = 4.77, 95% confidence interval 1.11 to 20.49) and dry mouth (odds ratio = 5.19, 95% confidence interval 1.15 to 23.51) than did placebo, but there was no statistically significant difference in other possible adverse effects. REVIEWER'S CONCLUSIONS: Data suggest tricyclic antidepressants are of unlikely benefit in the treatment of depression in pre pubertal children. There is marginal evidence to support the use of tricyclic antidepressants in the treatment of depression in adolescents, although the magnitude of effect is likely to be moderate at best.

Long term benzodiazepine use for insomnia in patients over the age of 60: discordance of patient and physician perceptions.

BACKGROUND: The aim of this study was to determine and compare patients' and physicians' perceptions of benefits and risks of long term benzodiazepine use for insomnia in the elderly. METHODS: A cross-sectional study (written survey) was conducted in an academic primary care group practice in Toronto, Canada. The participants were 93 patients over 60 years of age using a benzodiazepine for insomnia and 25 physicians comprising sleep specialists, family physicians, and family medicine residents. The main outcome measure was perception of benefit and risk scores calculated from the mean of responses (on a Likert scale of 1 to 5) to various items on the survey. RESULTS: The mean perception of benefit score was significantly higher in patients than physicians (3.85 vs. 2.84, p < 0.001, 95% CI 0.69, 1.32). The mean perception of risk score was significantly lower in patients than physicians (2.21 vs. 3.63, p < 0.001, 95% CI 1.07, 1.77). CONCLUSIONS: There is a significant discordance between older patients and their physicians regarding the perceptions of benefits and risks of using benzodiazepines for insomnia on a long term basis. The challenge is to openly discuss these perceptions in the context of the available evidence to make collaborative and informed decisions.
