The asthma year in Swedish pharmacies: a nationwide information and pharmaceutical care program for patients with asthma.

OBJECTIVE: To increase the understanding of asthma among patients and the general public in Sweden and to increase the collaboration among healthcare personnel for the benefit of asthma patients. DESIGN: Based on the results from problem detection studies, Apoteksbolaget, the national organization for pharmacies in Sweden, designed a program to educate healthcare professionals and the public about asthma. Entitled the "Asthma Year," all pharmacy staffs were offered education on asthma, patients were provided written information and audiovisual materials, and the general public was made more aware of asthma through local media. SETTING: Pharmacies, healthcare centers, hospital outpatient areas, libraries, places of work, and domestic airports. PARTICIPANTS: All pharmacy staffs (12,000 persons) were offered an education on asthma. Patients with asthma were offered brochures and leaflets in pharmacies and information in the pharmacy magazine Apoteket. The general public received information about asthma through posters, radio, and television. MAIN OUTCOME MEASURES: The evaluations of the Asthma Year indicate that the activities had an impact on the public, on patients with asthma, and on the pharmacy staffs. RESULTS: About 4.5 million people in Sweden (42% of the population) observed the Asthma Year or received information about asthma, and 49% of the patients learned something new about their disease. Twice as many patients used steroid therapy regularly after the campaign than before. Of the pharmacy staffs, 96% were favorable to the idea of working with campaign years and 85% believed that they were personally involved with the activities. CONCLUSIONS: Patient outcomes in terms of reduced morbidity have not been possible to document, but the number of deaths from asthma in Sweden decreased from 438 during the previous year to 398 during the Asthma Year.

Evidence-based medicine in general practice: beliefs and barriers among Australian GPs.

If implemented, evidence-based medicine (EBM) in general practice will improve health outcomes for patients. This paper examines the views of 60 Australian general practitioners about EBM. While 57% of respondents had a computer in their surgery, 15% had Internet access and only 3% had access to the Cochrane Library at work. The most commonly cited barrier to EBM was 'patient demand for treatment despite lack of evidence for effectiveness' (45%). The next three most highly rated barriers related to lack of time. For each of three tasks of EBM, namely searching for evidence, appraising evidence and discussing the implications of evidence with patients, lack of time was rated as a 'very important barrier' by significantly more participants than lack of skills (McNemar's tests: chi2(1) = 7.1, P = 0.008, chi2(1) = 14.0, P = 0.001 and chi2(1) = 9.0, P = 0.003, respectively). Preferred resources for EBM included clinical practice guidelines (rated as 'very useful' by 55%) and journals that summarize research evidence, for example Evidence-based Medicine (52%). Systematic reviews were considered 'very useful' by only 15% of respondents, consistent with our finding that 30% did not understand the term 'systematic review'. Furthermore, 43% did not understand 'meta-analysis'. A minority indicated they understood the terms 'relative risk' (23%), 'absolute risk' (28%) and 'number needed to treat' (15%) sufficiently to explain to others. Skills development is crucial to achieve EBM in general practice.

Accessibility and use of touchscreens by black and ethnic minority groups in the three cities project.

OBJECTIVES: The public are being encouraged by Government, at a national level, to take a greater role in the management of their health and healthcare but information to support this is not always accessible to black and ethnic minority group members who do not speak or read English. This study looks at the feasibility of providing health-related information in a multilanguage format through a touchscreen kiosk. DESIGN: Three touchscreen kiosks were programmed with information on 10 health topics translated into five languages: Chinese, Bengali, Gujarati, Urdu and Mirpuri Punjabi. Information was provided orally and in written format. Over an 18-month period the touchscreens were rotated between settings including health centres and libraries, located in deprived areas of Leicester, Sheffield and Nottingham. Information was logged on each individual user with respect to language used, topic selected, age group and gender of user. A number of users were invited to complete a short questionnaire about their use and ease of use of the touchscreen. RESULTS: Touchscreens were accessed by 2,456 people across all ages, 53% of whom were male. Urdu and Gujarati were the most frequently accessed languages (37 and 38%, respectively) and Bengali used least (9%). There was some variation in use by setting. Most of the 508 people questioned who had used the touchscreen found it easy to use. Ease of use was related to home computer use and to being younger in age. The five most popular topics accessed by 12% or more users were stress, diabetes, blood pressure, healthy eating and exercise. Topic choice varied by language used by males but not by females. CONCLUSION: Touchscreens providing health information in ethnic minority languages can be successfully accessed by black and ethnic minority groups, particularly those living in deprived areas. Touchscreens proved acceptable to, and were used by, the targeted audience.

[Graduated compression stockings in surgery -- optional or obligatory?].

BACKGROUND: Graduated compression stockings (GCS) can effectively reduce postoperative deep vein thrombosis (DVT) and their use is recommended by expert committees. However, it appears that GCS are not frequently used. The objectives of this study are to evaluate the customary use of GCS in surgical settings in the City of Hamburg, Germany, and to present evidence on the effectiveness of GCS. METHODS: A questionnaire on the use of thromboprophylaxis was sent to 48 surgeons in Hamburg. In addition, a comprehensive search for randomized-controlled trials, reviews, and meta-analyses indexed in MEDLINE (1984-06/2002) and the Cochrane Library (Issue 2, 2002) was conducted to show the effectiveness of GCS compared to nontreatment, other antithrombotic methods, or combined treatment. RESULTS: Of 48 surgeons 39 responded. Seven surgeons dismissed the use of GCS for thromboprophylaxis, 3 used GCS alone, 25 GCS in combination with heparin, and 4 used GCS only for patients at high risk. The review of the literature revealed the effectiveness of GCS in general and for abdominal surgical patients. Enhanced benefit is suggested when combining GCS with another intervention such as low-dose unfractionated heparin. Single application of GCS in orthopedic surgical or neurosurgical patients using venography showed no effect when compared to combined treatment of GCS and low molecular weight heparin. Trials with patients undergoing gynecological and urological surgeries are rare. There is a lack of trials investigating health-related quality of life and costs associated with the use of GCS. Complications are poorly reported. A determination as to the appropriate length of stockings is presently not possible. CONCLUSIONS: GCS should be integral part of DVT prophylaxis in surgical departments. Their ineffectiveness is likely in some surgical populations.

Surgical management of early stage invasive breast cancer: a practice guideline.

OBJECTIVES: To assess the available evidence on sentinel lymph-node biopsy, and to examine the long-term follow-up data from large randomized phase III trials comparing breast-conserving therapy with mastectomy in order to make recommendations on the surgical management of early invasive breast cancer (stages I and II), including the optimum management of the axillary nodes: for the breast--modified radical mastectomy or breast-conserving therapy; for the axilla--complete axillary node dissection, axillary dissection of levels I and II lymph nodes, sentinel lymph-node biopsy or no axillary node surgery. OUTCOMES: Overall survival, disease-free survival, local recurrence, distant recurrence and quality of life. EVIDENCE: MEDLINE, EMBASE, the Cochrane Library databases and relevant conference proceedings were searched to identify randomized trials and meta-analyses. Two members of the Practice Guidelines Initiative, Breast Cancer Disease Site Group (BCDSG) selected and reviewed studies that met the inclusion criteria. The systematic literature review was combined with a consensus process for interpretation of the evidence to develop evidence-based recommendations. This practice guideline has been reviewed and approved by the BCDSG, comprising surgeons, medical oncologists, radiation oncologists, pathologists, a medical sociologist, a nurse representative and a community representative. BENEFITS, HARMS AND COSTS: Breast-conserving therapy (lumpectomy with levels I and II axillary node dissection, plus radiotherapy) provides comparable overall and disease-free survival to modified radical mastectomy. Levels I and II axillary dissection accurately stages the axilla and minimizes the morbidity of axillary recurrence but is associated with lymphedema in approximately 20% of patients and arm pain in approximately 33%. Currently, there is insufficient data regarding locoregional recurrence and long-term morbidity associated with sentinel-node biopsy to advocate it as the standard of care. Breast-conserving therapy may offer an advantage over mastectomy in terms of body image, psychological and social adjustment but appears equivalent with regard to marital adjustment, global adjustment and fear of recurrence. RECOMMENDATIONS: Women who are eligible for breast-conserving surgery should be offered the choice of either breast-conserving therapy with axillary dissection or modified radical mastectomy. Removal and pathological examination of levels I and II axillary lymph nodes should be the standard practice in most cases of stages I and II breast carcinoma. There is promising but limited evidence to support recommendations regarding sentinel lymph-node biopsy alone. Patients should be encouraged to participate in clinical trials investigating this procedure. VALIDATION: A draft version of this practice guideline and a 21-item feedback questionnaire was circulated to 201 practitioners in Ontario. Of the 131 practitioners who returned the questionnaire, 98 (75%) completed the survey and indicated that the report was relevant to their clinical practice. Eighty (82%) of these practitioners agreed that the draft document should be approved as a practice guideline.

Systematic review of measures and their concepts used in published studies focusing on the treatment of acute inflammatory arthritis.

To identify outcome measures and concepts cited in published studies focusing on the treatment of acute inflammatory arthritis, and to identify and quantify the concepts contained in these measures using the International Classification of Functioning, Disability and Health (ICF) as a reference. This 'research perspective' is part of the development process for an ICF core set in acute arthritis. Electronic searches of Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, Pedro and the Cochrane Library from January 2000 to July 2004 were carried out. Data on the outcome measures and patient characteristics for the included studies were extracted. The items of the identified questionnaires and their underlying concepts were specified and then linked to ICF categories using standardized linkage rules. From the 401 abstracts retrieved, 104 studies met the inclusion criteria. From these studies, 38 formal assessment instruments, 62 single clinical measures, 66 technical measures and 14 clinical criteria were identified. A total of 966 concepts were extracted, and 84.7% of these concepts could be linked to ICF categories. The concepts contained in measures named in more than 5% of the studies were represented by 34 second-level ICF categories. Ten (30%) of the 34 categories belong to the component "Body Functions", 3 (9%) to the component "Body Structures" and 21 (61%) to the component "Activities and Participation". The ICF provides a valuable reference to identify and quantify the concepts of outcome measures focusing on the management of patients with acute inflammatory arthritis. Our findings indicate there is good agreement on 'what should be measured' in acute inflammatory arthritis to allow for a comparison of patient populations.

Applying evidence-based surgery in daily clinical routine: a feasibility study.

BACKGROUND: Although the word evidence-based medicine (EBM) has gained wide popularity, only a few studies have evaluated how EBM works in clinical practice. METHODS: We have prospectively evaluated the feasibility of evidence-based trauma surgery. Orthopaedic trauma surgeons were asked to produce clinical questions related to the treatment of current patients. An informaticist searched the literature (Medline, Cochrane Library, practice guidelines and textbooks) and reported the findings on every following day. The study's main endpoints were the rate of questions for which relevant evidence (>level V) was available and the time necessary to find and critically appraise medical evidence. RESULTS: In total, 44 EBM questions were formulated, mainly concerning treatment options. PubMed was searched for 39 questions, textbooks for 14, the Cochrane Library for 11, online guidelines for 9 and other sources were used for 4 questions. On average, 157 text items (three per questions) were identified as potentially relevant. Journal articles predominated (83%) over textbooks (10%). Sixty-eight percent of the questions (30 of 44) were answered, either on the basis level 1 (n=13 questions), level 2 (n=6), or level 4 evidence (n=14). Trying to answer a question required 53 min on average, split up between 39 min of database searches and 25 min of obtaining full text articles. In four cases, the evidence suggested a change in clinical management. The physicians were very appreciative of our project and found the provided evidence very helpful for their clinical decisions. CONCLUSIONS: Time will be the main barrier against the introduction of clinical EBM. It is likely that clinicians reduce EBM to those situations where evidence is likely to be found. Although the impact of EBM on patient-care was limited, the concept of EBM was successfully implemented.

A study of personal digital assistants to enhance undergraduate clinical nursing education.

This study reports on personal digital assistants (PDAs) as a means to prepare nurse professionals who value and seek current information. An interdisciplinary team of nursing and library faculty, information technology and bookstore staff, students, and educational consultants developed this project. A pre-post and comparative group design of second-degree students in the accelerated and traditional baccalaureate nursing degree (BSN) options was used to examine students' information-seeking behaviors, and the effectiveness and cost of innovation strategies associated with incorporation of PDAs into students' clinical practice. Results of this study support PDAs as an effective student learning resource, especially for reference materials. The student group with PDAs had increasing numbers of questions associated with clinical situations and a greater recognition of the need to use current resources. Students made substantial use of their PDAs and health team members, while decreasing reliance on textbooks and clinical faculty. Students' use of and satisfaction with this technology is linked to access speed and readability. Providing faculty with PDAs is recommended to enhance their comfort with and incorporation of PDAs into clinical teaching.

Frequency and determinants of nonpublication of research in the stroke literature.

BACKGROUND AND PURPOSE: Selective nonpublication will yield publication bias and a published literature imperfectly representative of the full range of scientific findings. We evaluated the proportion of research abstracts presented at the leading United States research meeting in stroke, the International Stroke Conference (ISC), which were subsequently published as full-length articles and investigated the factors associated with full manuscript publication. METHODS: Features of all abstracts presented at the annual ISC meeting in February 2000 were analyzed. Search of the National Library of Medicine PubMed database and written communication with abstract authors was performed to determine conversion of abstracts to fully published manuscripts over the subsequent 5 years. RESULTS: Among the 353 abstracts presented at the 2000 International Stroke Conference, 108 were oral presentations and 245 posters. Overall, 202/353 (62.3%) resulted in full-length publications, with a median time to publication of 15 months. In multivariate analysis, factors increasing likelihood of full-length publication were: platform rather than poster presentations (odds ratio [OR] 3.0, 95% CI, 1.6 to 5.5), authors with a university affiliation (OR 2.2, 95% CI, 1.2 to 4.1), and European region of origin (OR 2.2, 95% CI, 1.1 to 4.4), whereas topic concerning community/risk factors decreased the likelihood of publication (OR 0.3, 95% CI, 0.16 to 0.74). Positive results, multicenter collaboration and industry sponsorship did not affect publication rate. CONCLUSIONS: Approximately 1 of every 3 abstracts presented at an international stroke meeting was not published as a full manuscript within 5 years. Poster abstracts were less likely to be published in full manuscript form than oral presentations.

Survey of CAG/CTG repeats in human cDNAs representing new genes: candidates for inherited neurological disorders.

Expansion of polymorphic CAG and CTG repeats in transcripts is the cause of six inherited neurodegenerative or neuromuscular diseases and may be involved in several other genetic disorders of the central nervous system. To identify new candidate genes, we have undertaken a large-scale screening project for CAG and CTG repeats in human reference cDNAs. We screened 100 128 brain cDNAs by hybridization. We also scanned GenBank expressed sequence tags for the presence of long CAG/CTG repeats in the extremities of cDNAs from several human tissues. Of the selected clones, 286 were found to represent new genes, and 72 have thus far been shown to contain CAG/CTG repeats. Our data indicate that CAG/CTG repeated 10 or more times are more likely to be polymorphic, and that new 3'-directed cDNAs with such repeats are very rare (1/2862). Nine new cDNAs containing polymorphic (observed heterozygote frequency: 0.05-0.90) CAG/CTG repeats have been currently identified in cDNAs. All of the cDNAs have been assigned to chromosomes, and six of them could be mapped with YACs to 1q32-q41, 3p14, 4q28, 3p21 and 12q13.3, 13q13.1-q13.2, and 19q13.43. Three of these clones are highly polymorphic and represent the most likely candidate genes for inherited neurodegenerative diseases and, perhaps, neuropsychiatric disorders of multifactorial origin.

A comprehensive survey for polymorphisms in the bovine IFN-gamma gene reveals a highly polymorphic intronic DNA sequence allowing improved genotyping of Bovinae.

This study aimed to identify interferon-gamma (IFN-gamma) gene variants in cattle for diagnostic purposes. Therefore, the entire bovine IFN-gamma gene (BoIFNG) and 2605 bp of its promoter DNA were sequenced. The BoIFNG DNA sequence conforms to the published part of Bo-IFN-gamma cDNA. Primer extension experiments show the presence of a 5' extension of exon 1 by 42 nucleotides (nt). One SINE element (Bov-A2) is located in the 5'-region, and two SINE elements (Bov-tA, Bov-B) are contained in the 3'-region of BoIFNG. The variants were detected by comparative sequence analysis of PCR amplicons from different bovine species. Four polymorphic mononucleotide repeats are situated in the promoter and in intron 1. Four distinct series of single nucleotide polymorphisms (SNP) were found in functionally important regions of BoIFNG. The region between the two intron 1 microsatellites contains the highest density of SNPs in Bos taurus breeds. One G-T transversion in the coding region of exon 1 causes a Gly(14) to Val(14) exchange in the BoIFNG signal peptide of different bovine species. A G-A transition in exon 2 encodes a Ser(19) to Asn(19) change in the mature protein of the Tibetan yak. Genotyping of randomly sampled Holstein Friesian cows at selected SNPs and of both intron 1 microsatellites revealed two dominant BoIFNG microhaplotypes. The detected SNPs improve the recently reported genotyping system of cattle.

Smoking, atopy and certain furry pets are major determinants of respiratory symptoms in children: the International Study of Asthma and Allergies in Childhood Study (Ireland).

BACKGROUND: Environmental, cultural and health care differences may account for variation among countries in the prevalence of asthma and respiratory symptoms in teenagers. OBJECTIVE: To examine the prevalence of respiratory symptoms and the level of diagnosis, and to compare determinants of asthma and severe wheeze in two countries. METHODS: Self-completion questionnaires based on the International Study of Asthma and Allergies in Childhood (ISAAC) protocol were provided to school children in Ireland (Republic and Northern Ireland). In the Republic of Ireland, all children in classes largely aged 13-14 years from 30 post-primary schools were selected by random sampling stratified by school size, composition and Health Board in Spring 1995. In Northern Ireland, all children largely aged 13-14 years of age from 26 post-primary schools were selected by random sampling stratified by school type, composition and Education and Library Board in Spring 1996. RESULTS: Questionnaires were completed by 2,364 children from Northern Ireland and 2,671 from the Republic, about 90% of those eligible to participate. The prevalences of wheeze at various levels of severity, of diagnosed asthma and of treated wheeze were very similar in Northern Ireland and the Republic of Ireland. A significant proportion of those reporting more severe symptomatology (four or more attacks of wheeze in the past 12 months and/or one or more nights disturbed and/or moderate or greater disruption of daily activities and/or speech restriction due to wheeze) had been neither diagnosed nor treated for asthma (20-37%). To investigate the determinants of the more severe symptomatology of asthma or treated wheeze a series of stepwise multiple regression analyses was performed. A history of atopy, cigarette smoking, the possession of a furry pet other than a dog or cat and age were each independently associated with severe wheeze, whilst atopy, a furry pet (as above) and gender were each independently associated with asthma or treated wheeze. CONCLUSIONS: Cigarette smoking is closely associated with the reporting of significant respiratory symptoms together with atopy and exposure to furry pets. Some 20-37% of severe symptoms were neither diagnosed nor treated as asthma.

Questionnaires to assess urinary and anal incontinence: review and recommendations.

PURPOSE: We reviewed and provide recommendations about the most scientifically robust and appropriate questionnaires for evaluating symptoms and the quality of life impact of urinary and/or anal incontinence, and vaginal and pelvic floor problems. We also investigated the use of these questionnaires in randomized, controlled trials of treatment strategies. MATERIALS AND METHODS: The Symptom and Quality of Life Committee of the International Consultation on Incontinence performed a systematic review of questionnaires related to urinary and anal incontinence, and vaginal and pelvic floor problems, searching MEDLINE, The Cochrane Library and other electronic databases between 2001 and 2004. RESULTS: A total of 23 robust and relevant questionnaires could be recommended in clinical practice and research. The development of questionnaires to assess anal incontinence, and pelvic floor and vaginal problems has been limited with some promising measures but with none achieving the highest level of rigor. From 2001 to 2004 there were 150 published randomized trials of treatments for incontinence. Increasingly trials of incontinence are using recommended measures (38% of those for urinary incontinence and 22% of those for anal incontinence used the highest quality questionnaires in 2001 to 2004) but none of vaginal and pelvic floor problems used recommended questionnaires. CONCLUSIONS: With increasing acknowledgment of the value of patient based assessment much attention has been given to the development of questionnaires to assess symptoms and quality of life. Sufficient measures are now available for urinary incontinence, and researchers and clinicians are encouraged to use the 18 achieving the highest level of rigor and their validated translations. In contrast, the development of questionnaires for anal incontinence and pelvic/vaginal problems is in its infancy and further study in this area is needed. Randomized trials of treatments for incontinence should use only questionnaires achieving the highest level of scientific rigor.

Proteorhodopsin genes are distributed among divergent marine bacterial taxa.

Proteorhodopsin (PR) is a retinal-binding bacterial integral membrane protein that functions as a light-driven proton pump. The gene encoding this photoprotein was originally discovered on a large genome fragment derived from an uncultured marine gamma-proteobacterium of the SAR86 group. Subsequently, many variants of the PR gene have been detected in marine plankton, via PCR-based gene surveys. It has not been clear, however, whether these different PR genes are widely distributed among different bacterial groups, or whether they have a restricted taxonomic distribution. We report here comparative analyses of PR-bearing genomic fragments recovered directly from planktonic bacteria inhabiting the California coast, the central Pacific Ocean, and waters offshore the Antarctica Peninsula. Sequence analysis of an Antarctic genome fragment harboring PR (ANT32C12) revealed moderate conservation in gene order and identity, compared with a previously reported PR-containing genome fragment from a Monterey Bay gamma-proteobacterium (EBAC31A08). Outside the limited region of synteny shared between these clones, however, no significant DNA or protein identity was evident. Analysis of a third PR-containing genome fragment (HOT2C01) from the North Pacific subtropical gyre showed even more divergence from the gamma-proteobacterial PR-flanking region. Subsequent phylogenetic and comparative genomic analyses revealed that the Central North Pacific PR-containing genome fragment (HOT2C01) originated from a planktonic alpha-proteobacterium. These data indicate that PR genes are distributed among a variety of divergent marine bacterial taxa, including both alpha- and gamma-proteobacteria. Our analyses also demonstrate the utility of cultivation-independent comparative genomic approaches for assessing gene content and distribution in naturally occurring microbes.

Intrauterine insemination versus timed intercourse for cervical hostility in subfertile couples.

The postcoital test has poor diagnostic and prognostic characteristics. Nevertheless, some physicians believe it can identify scanty or abnormal mucus that might impair fertility. One way to avoid "hostile" cervical mucus is intrauterine insemination. With this technique, the physician injects sperm directly into the uterine cavity through a small catheter passed through the cervix; the theory is to bypass the "hostile" cervical mucus. Although most gynecologic societies do not endorse use of intrauterine insemination for hostile cervical mucus, some physicians consider it an effective treatment for women with infertility thought the result of cervical mucus problems. The aim of this review was to determine the effectiveness of intrauterine insemination with or without ovarian stimulation in women with cervical hostility who failed to conceive.We searched Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library Issue 2, 2005, MEDLINE (1966 to June 2005), EMBASE (1980 to June 2005), POPLINE (to June 2005), and LILACS (to June 2005). In addition, we contacted experts and searched the reference list of relevant articles and book chapters. We included randomized and quasirandomized, controlled trials comparing intrauterine insemination with intercourse timed at the presumed fertile period. Participants were women with cervical hostility who failed to conceive for at least 1 year. We assessed the titles and abstracts of 386 publications and 2 reviewers independently abstracted data on methods and results from 5 studies identified for inclusion. The main outcome is pregnancy rate per couple. We did not pool the outcomes of the included 5 studies in a meta-analysis resulting from the methodological quality of the trials and variations in the patient characteristics and interventions. Narrative summaries of the outcomes are provided. Each study was too small for a clinically relevant conclusion. None of the studies provided information on important outcomes such as spontaneous abortion, multiple pregnancies, and ovarian hyperstimulation syndrome. There is no evidence from the published studies that intrauterine insemination is an effective treatment for cervical hostility. Given the poor diagnostic and prognostic properties of the postcoital test and the observation that the test has no benefit on pregnancy rates, intrauterine insemination (with or without ovarian stimulation) is unlikely to be a useful treatment for putative problems identified by postcoital testing. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES: After completion of this article, the reader should be able to recall that there is a lack of adequate studies that support that intrauterine insemination (IUI) is an effective treatment of cervical hostility, explain that the postcoital test has poor diagnostic and prognostic properties, and state that the use of both tests has no benefit on pregnancy rates. EDITOR'S NOTE: Although many assisted reproductive technology (ART) programs no longer perform postcoital tests, many perform intrauterine insemination (IUI), often with gonadotropins or clomiphene citrate, in their subfertile patients. Therefore, this review article will be of value to our readers who treat subfertile patients with IUI, whether or not they perform postcoital tests.

Cancer symptom assessment instruments: a systematic review.

PURPOSE: A variety of assessment instruments have been created to identify cancer symptoms. We reviewed systematically cancer symptom assessment instruments published in English. METHODS: A systematic search of the MEDLINE database, Cochrane Library, Cumulative Index of Nursing and Allied Health Literature (CINAHL), and EMBASE was performed. Non-peer-reviewed articles were identified through BIOSIS. Articles were accessed through the related article links in PubMed and references were searched by hand. Studies were included if the instrument had symptom assessment as the primary outcome. Quality-of-life instruments were excluded. RESULTS: We identified 21 instruments; some had undergone modification or validation. An additional 28 studies examined symptom prevalence and interrelations; many involved symptom checklists. Studies varied in design, patient characteristics, symptoms, and outcome. Meta-analysis was not possible due to heterogeneity in design, study outcomes, and validation. Seventy-six articles and two conference abstracts (derived from MEDLINE, Cochrane, CINAHL, EMBASE, BIOSIS, related articles link in PubMed, and search by hand) met inclusion/exclusion criteria. The electronic search (without related links) yielded only 26% of those articles and conference abstracts that met inclusion criteria. Searches by hand of related articles identified 59% of studies. CONCLUSION: Twenty-one instruments were identified as appropriate for clinical use. The instruments vary in symptom content and extent of psychometric validation. Both comprehensive and shorter instruments have been developed, and some instruments are intended for specific symptom assessment or symptoms related to treatment. There is no ideal instrument, and the wide variety of instruments reflects the different settings for symptom assessment. Additional research is necessary.

A study comparing centralized CD-ROM and decentralized intranet access to MEDLINE.

OBJECTIVE: The purpose of this study was to evaluate the efficacy of a decentralized intranet access in each medical department as opposed to centralized unique MEDLINE access in the medical library. DESIGN: A two-phase questionnaire to evaluate MEDLINE use was given to junior and senior physicians at Rouen University Hospital (RUH). Phase I (August-October 1996) corresponded to a time period when centralized access was the only means of access available and phase II (August-October 1997) to a time period following the introduction of decentralized intranet access. RESULTS: A total of 168 physicians filled out at least one phase of the questionnaire, among whom 123 (73%) filled out both phases. Use of MEDLINE significantly increased in 1997 (average of 10.2+/-1.1 searches in three months) versus 1996 (average of 4.9+/-0.7 searches in three months, P<0.0001). The aim of searches changed, becoming significantly more care oriented in phase II (P<0.0001). The number of searches performed by the physicians alone increased (P<0.0001) and searches performed by the librarian decreased (P<0.0001) in phase II. The method of searches also changed, as searches by author (P< 0.0001), by journal (P = 0.0042), and by free word (P = 0.0027) increased in phase II. Knowledge of the following concepts of MEDLINE significantly increased: explosion (P<0.0001), scope note (P<0.0001), Abridged Index Medicus (AIM) journals (P<0.0001), Medical Subject Headings (MeSH) qualifier (P<0.0001), and focus (P<0.0001). CONCLUSION: A decentralized intranet access to MEDLINE increased the number of searches and knowledge of this bibliographic database. MEDLINE intranet access modified the purpose and the methods of searching.

The East Flanders Prospective Twin Survey (EFPTS).

The East Flanders Prospective Twin Survey (EFPTS) is a registry of multiple births in the province of East-Flanders, Belgium. It has several unique features: it is population-based and prospective, with the possibility of long-term follow-up; the twins (and higher order multiple births) are ascertained at birth; basic perinatal data are recorded; chorion type and zygosity are established; and since 1969 placental biopsies have been taken and frozen at -20 degrees C for later determination of genetic markers. The EFPTS is the only large register that includes placental data and allows differentiation of three subtypes of monozygotic (MZ) twins based on the time of the initial zygotic division: the dichorionic-diamnionic pairs (early, before the fourth day after fertilisation), the monochorionic-diamnionic pairs (intermediate, between the fourth and the seventh day post fertilisation), and the monochorionic-monoamnionic pairs (late, after the eight day post fertilisation). This added a new dimension to didymology (the science of twins; delta iota delta upsilon mu omicron zeta = twins): the timing of twinning. Studies can be initiated on primary biases, those originating "in utero". Such studies may throw new light on the controversy over the validity of the classic twin method, the consequences of early embryological events (before and just after implantation of the embryo), the origin of congenital malformations, the sex proportion of multiples, the gene-environment interactions as far as intrauterine environment is concerned, to name but a few.
