An epidemiological assessment of immunization programme participation in the Philippines.

Because a large proportion of preschool children failed to present for free diphtheria-pertussis-tetanus (DPT) immunizations in a poor, rural area of the Philippines, we undertook an epidemiological analysis of their characteristics. The parents of 159 children were interviewed to determine the demographic, attitudinal, knowledge, and administrative correlates of immunization status. Logistic regression was used to model immunization status. Children were less likely to be immunized if they had a high score on an Adversity Index (composed of measures of the weather, the number of visits the team made, the distance, the appropriateness of the time of day, and miscellaneous problems), if they received health care from a native mother and child health specialist, if a parent was not on the town council, and if pain was an important deterrent. By contrast, many demographic and attitudinal measures that have traditionally been thought to predict health behaviour were not useful discriminators. Recommendations are made for immunization programme management. The general use of this method for programme planning is elaborated.

GenBank.

The GenBank sequence database continues to expand its data coverage, quality control, annotation content and retrieval services for the scientific community. Besides handling direct submissions of sequence data from authors, GenBank also incorporates DNA sequences from all available public sources; an integrated retrieval system, known as Entrez, also makes available data from the major protein sequence and structural databases, and from U.S. and European patents. MIDLINE abstracts from published articles describing the sequences are also included as an additional source of biological annotation for sequence entries. GenBank supports distribution of the data via FTP, CD-ROM, and E-mail servers. Network server-client programs provide access to an integrated database for literature retrieval and sequence similarity searching.

Compilation of DNA sequences of Escherichia coli K12 (ECD and ECDC; update 1995).

We have compiled the DNA sequence data for Escherichia coli available from the GenBank and EMBL data libraries and independently from the literature. Unlike the previous updates of our E.coli databases, we provide the most recent version preferentially via the World Wide Web System (use URL: http://susi.bio.unigiessen.de/usr/local/www++ +/html/ecdc.html). Our database includes an assembled set of contiguous sequences. Each of these contigs compiles all available sequence information, including those derived from a variety of elder sequences. The organization of the database allows one to find the exact physical location of each individual gene or regulatory region, even regarding discrepancies in nomenclature. The WWW program allows access into the original EMBL and SWISSPROT datafiles. A FASTA and BLAST search may be performed online. Besides the WWW format a flat file version may be obtained via ftp. The complete compilation, including a full set of genetic map data and the E.coli protein index, can be obtained in machine readable form from the EMBL data library as a part of the CD-ROM issue of the EMBL sequence database, released and updated every three months. After deletion of all detected overlaps a total of 3 333 878 individual bp was determined by the end of September 1995. This corresponds to a total of 71.71% of the entire E.coli chromosome consisting of about 4720 kbp. About 94 kbp (2%) are available additionally, but have not yet been definitely mapped.

An interdisciplinary effort to help patients with limited prescription drug benefits afford their medication.

BACKGROUND: Patients without prescription benefits present a significant challenge to health care providers. The inability of patients to afford medication may serve as a barrier to adherence and may ultimately result in poor patient outcomes. In this report, we describe the system used at a university-based adult internal medicine center to assist patients in affording medication. METHODS: Patients in need of prescription assistance are identified by any member of the interdisciplinary team, which consists of physicians, clinical pharmacists, nurses, a social worker, a financial counselor, and a dietitian. Medication profiles are reviewed to identify less expensive alternatives. State, federal, institutional, and pharmaceutical company assistance program eligibility is determined, and the appropriate program is accessed. RESULTS: The described approach is effective in assisting patients without prescription benefits with the procurement of medication. CONCLUSION: Use of this interdisciplinary approach is an innovative solution to a common problem encountered in the outpatient setting.

Cost-effectiveness of automated external defibrillators in public places: pro.

PURPOSE OF REVIEW: Placement of automated external defibrillators in public facilities is a cost-effective treatment for out-of-hospital cardiac arrests. This review describes the literature citing the benefits of early defibrillation, ease of use, and relative cost of automated external defibrillators. RECENT FINDINGS: Placement of automated external defibrillators in public places was recommended by the American Heart Association in the early 1990s. Compared with waiting for traditional emergency medical services, immediate use of automated external defibrillators by laypersons can dramatically increase survival to hospital discharge rates. Placement of automated external defibrillators at locations such as casinos, airports, and airplanes that are frequented by large numbers of at-risk people is cost-effective compared with other economically acceptable health measures. Studies using simulations to predict numbers of quality-adjusted life years that would be gained from implementation of public access defibrillation programs in high-incidence locations find that the cost would be less than the typically acceptable 50,000 dollars per quality-adjusted life year. The cost estimates, however, depend on the incidence of cardiac arrest at the sites, with low-incidence sites being prohibitively expensive. SUMMARY: Automated external defibrillators appear to be cost-effective in locations with high incidences of cardiac arrest.

MOP-UP: an online tool for finding strain-specific primers or motifs in DNA or protein alignments.

MOP-UP is a web-based application that enables efficient searching of nucleic acid or amino-acid alignments for sequences or motifs that are unique to a subset of the members represented in the alignment. This has applications in the design of assays that aim to detect particular strains or species. Since molecular-based characterisation of microbes is becoming increasingly important, MOP-UP can aid microbiologists in finding the best loci on which to base such assays. The program is accessible at: http://www.hpa.org.uk/srmd/bioinformatics/tools/mop-ups.htm.

Serological markers for prediction of response to anti-tumor necrosis factor treatment in Crohn's disease.

OBJECTIVES: The use of monoclonal anti-tumor necrosis factor (TNF) antibodies (infliximab, Remicade) is a new therapeutic approach for severe refractory luminal or fistulizing, Crohn's disease (CD). However, up to 30% of patients do not respond to this treatment. So far, no parameters predictive of response to anti-TNF have been identified. Our aim was to determine whether serological markers ASCA (anti-Saccharomyces cerevisiae antibodies) or pANCA (perinuclear antineutrophil cytoplasmic antibodies) could identify Crohn's patients likely to benefit from anti-TNF therapy. METHODS: Serum samples of 279 CD patients were analyzed for ASCA and pANCA before anti-TNF therapy. A blinded physician determined clinical response at week 4 (refractory luminal CD) or week 10 (fistulizing CD) after the first infusion of infliximab (5 mg/kg). RESULTS: Overall, there was no relationship between ASCA or pANCA and response to therapy. However, lower response rates were observed for patients with refractory intestinal disease carrying the pANCA+/ASCA- combination, although this lacked significance (p = 0.067). CONCLUSIONS: In this cohort of infliximab-treated patients, neither ASCA nor pANCA could predict response to treatment. However, the combination pANCA+/ASCA- might warrant further investigation for its value in predicting nonresponse in patients with refractory luminal disease.

The benefits of telephone-access medical consultation.

A major disadvantage of rural medical practice is the limited reserve of consultative options. To determine the perceived clinical utility and educational impact of the West Virginia University Medical Access and Referral System (MARS), a 24-hour prompt telephone-consultation service, a mailed questionnaire was administered to 303 West Virginia clinicians who had used MARS for infectious disease problems. The overall questionnaire response rate was 62 percent. Callers included family practitioners (35%), medical specialists (32%), surgical specialists (13%), pediatricians (11%), obstetricians (5%), and nonphysicians (4%). Major referral questions posed were therapeutic (60%), diagnostic (48%), and epidemiologic (10%) in nature. On a scale of 1 (not useful) to 5 (very useful), survey responders rated the overall clinical usefulness of MARS as either a 4 (22%) or 5 (76%). Callers felt that MARS consultation assisted in accurate case diagnosis in 80 percent of cases, and aided in successful therapeutic management of 96 percent of cases. An educational benefit was reported by 96 percent of responders. Physicians located in more rural, underserved areas tended to use MARS to a greater degree than colleagues in more populated, medically accessible areas (P < 0.005). These findings suggest that an academic telephone-access consultation program can be a clinically relevant and educational consultative tool for practicing clinicians, especially those located in rural areas.

Assessing community child passenger safety efforts in three Northwest Tribes.

OBJECTIVE: To identify strengths and weaknesses in community based child passenger safety programs by developing a scoring instrument and conducting observations of child restraint use in three Native American communities. SETTING: The three communities are autonomous Tribal reservations in the Pacific Northwest. Their per capita incomes and rates of unemployment are comparable. METHODS: In each community, 100 children under 5 years old were observed for car seat use. A six item community assessment tool (100 points maximum) awarded points for such items as the type (primary or secondary) and enforcement of child restraint laws; availability of car seats from distribution programs; extent of educational programs; and access to data on vehicle injuries. RESULTS: For children from birth to 4 years, the car seat use rate ranged from 12%-21%. Rates for infants (71%-80%) far exceeded rates for 1-4 year old children (5%-14%). Community scores ranged from 0 to 31.5 points. There was no correlation between scores and observed car seat use. One reason was the total lack of enforcement of restraint laws. CONCLUSIONS: A community assessment tool can highlight weaknesses in child passenger efforts. Linking such a tool with an objective measure of impact can be applied to other injury problems, such as fire safety or domestic violence. The very process of creating and implementing a community assessment can enhance agency collaboration and publicize evidence based "best practices" for injury prevention. Further study is needed to address methodologic issues and to examine crash and medical data in relation to community child passenger safety scores.

Acne is not a stigma of HIV infection: a review of 36 patients.

INTRODUCTION: Several diseases with follicular occlusion have been described in HIV-infected patients and can appear isolated or associated with each other in an independent disease named 'HIV-associated follicular syndrome'. Worsening of cutaneous lesions during the course of infection in patients with previous acne vulgaris, late onset or severe forms of acne have been reported in HIV-infected patients. PATIENTS AND METHODS: A prospective study of 335 HIV-infected patients was performed in our hospital. A meticulous dermatological exploration in all patients was made, and multiple data were stored into a Microsoft Access 97 program. Patients diagnosed as having acne were considered separately, and we studied their characteristics. A statistical analysis with SPSS 9.0 (Statistical Package for the Social Sciences) was performed. RESULTS: Thirty-six patients (10.8%) were diagnosed as having acne. Papulopustular lesions were the most frequent clinical presentation. Most lesions were localized on the face or on the back, and 80% of patients had mild to moderate acne; 40% of them required no treatment and the remainder was treated with topical measures, oral antibiotics and isotretinoin. 85% of cases reported the onset of acne during adolescence or before HIV infection and without any relationship with this disease. No relation between acne intensity and stage of HIV infection was observed. A multivariate analysis showed that the most important variable was age. DISCUSSION: In contrast to previous reports, no greater intensity or modifications in acne lesions were observed in our HIV-infected patients during the course of the disease. In the majority of cases, cutaneous lesions started before HIV infection, during adolescence, and the most important factor for suffering from acne was young age. In contrast to data reported in the literature, no relation of acne lesions to CD4 lymphocyte count or AIDS case criteria was found in our patients. CONCLUSIONS: Acne in HIV-infected patients has characteristics similar to those in non-HIV-infected patients. The age is the most important factor for the appearance of lesions that usually develop during adolescence. Acne lesions are not modified by HIV infection, and no relationship with the severity of HIV infection has been observed.

Prevention of depressive symptoms through the use of distance technologies.

Psychoeducational materials can be disseminated at minimal expense through the use of distance technologies, offering an opportunity for prevention. The objective of this project was to develop and evaluate a psychoeducational computer program designed to prevent depressive symptoms. The program was accessible through the Internet or by touch-tone telephone. A total of 786 participants were randomly assigned either to the preventive intervention or to an information-only control condition. Over a three-month follow-up period, no differences between the groups were observed. However, three of the target variables (cognitive style, activity level, and sleep quality) were found to be strong predictors of whether a participant had an episode of major depression during the follow-up period.

Assessment of obstetric high risk factors in a developing country.

The detection of women with obstetric high-risk factors is now recognized as a major aim of antenatal care, especially in developing countries, and those factors most important in Papua New Guinea obstetric practice have been identified by a study of maternal deaths. The present study aimed to assess the value of the detection of these factors by comparing the outcomes of pregnancies with and without high risk factors. Home, health centre and hospital deliveries in two districts of Enga Province in the Papua New Guinea Highlands were studied. Of the total 2225 deliveries, 74% took place at home, the proximity of a health centre appearing to be a major determinant in the choice between home or supervised institutional delivery. Fifty-three per cent of women had at least one high risk factor, and 92% of these factors were historical. Eighty-two per cent of women had an uncomplicated normal delivery, while post-partum haemorrhage was the commonest complication, occurring in 7.6% of deliveries. This complication also caused all 4 maternal deaths. There was good correlation between delivery complications and the presence of high-risk factors, 70% of complications occurring in at-risk pregnancies. It is concluded that the detection of high-risk factors in pregnancy is very worthwhile. But, as a separate study has shown, the rate of detection antenatally could be improved, and until more health centres are constructed it will probably prove difficult to persuade all those at high risk to deliver under supervision.

Kangaroo--a pattern-matching program for biological sequences.

BACKGROUND: Biologists are often interested in performing a simple database search to identify proteins or genes that contain a well-defined sequence pattern. Many databases do not provide straightforward or readily available query tools to perform simple searches, such as identifying transcription binding sites, protein motifs, or repetitive DNA sequences. However, in many cases simple pattern-matching searches can reveal a wealth of information. We present in this paper a regular expression pattern-matching tool that was used to identify short repetitive DNA sequences in human coding regions for the purpose of identifying potential mutation sites in mismatch repair deficient cells. RESULTS: Kangaroo is a web-based regular expression pattern-matching program that can search for patterns in DNA, protein, or coding region sequences in ten different organisms. The program is implemented to facilitate a wide range of queries with no restriction on the length or complexity of the query expression. The program is accessible on the web at http://bioinfo.mshri.on.ca/kangaroo/ and the source code is freely distributed at http://sourceforge.net/projects/slritools/. CONCLUSION: A low-level simple pattern-matching application can prove to be a useful tool in many research settings. For example, Kangaroo was used to identify potential genetic targets in a human colorectal cancer variant that is characterized by a high frequency of mutations in coding regions containing mononucleotide repeats.
