Efficacy of the female condom as a barrier to semen during intercourse.

In 1996-1998, the authors measured prostate-specific antigen (PSA) in vaginal fluid to assess the frequency of female condom failure and to evaluate the association of self-reported failure with semen exposure. Women at low risk of sexually transmitted diseases (n = 210) were recruited in Birmingham, Alabama. They were trained to use the female condom, sample vaginal fluid before and after condom use, and complete forms to report problems during each use. Semen exposure was assessed by comparing pre- and postcoital PSA levels in vaginal fluid. A total of 175 women used 2,232 condoms. The rate of semen exposure ranged from 7% to 21% of condom uses, depending on the exposure criterion. Exposure was more likely (21-34%) and more intense (mean postcoital PSA, 24.7 ng/ml) if participants reported a mechanical problem versus other problems or no problems (exposure rate, 5-20% in both instances; mean postcoital PSA, 9.6 and 7.8 ng/ml, respectively). In logistic regression analyses for repeated measurements, user-reported problems accounted for less than 59% of the instances of semen exposure. The female condom prevented semen exposure in 79-93% of condom uses. Exposure was associated with user-reported problems but also occurred in their absence. Reported problems and semen exposure decreased with user experience.

Psychosis among substance users.

PURPOSE OF REVIEW: This work reviews the evidence that substances of abuse can cause psychosis in nonpsychotic persons. The review is based on the concept that psychosis exists in continuum. Studies examining substance use in, or its effect on, already psychotic individuals were not reviewed. RECENT FINDINGS: A substantial proportion of substance users experience psychosis. Use of cocaine, amphetamines, cannabis and alcohol seems to be associated with greater risk for psychosis. Severity and duration of use, age at the time of first use and vulnerability to develop psychosis by virtue of familial, possibly genetic and personality factors seem to be the determinants for the development of psychosis. Epidemiological and preliminary biological studies suggest that cannabis is a component cause in the development of schizophrenia. Evidence for the causative role of other substances is less systematic. SUMMARY: There exists strong evidence that abuse of substances is associated with greater risk for psychosis and preliminary evidence for their causative role in the development of psychosis. More systematic examination of this issue is likely to throw light on the neurobiology of psychosis and possibly help the vulnerable population in primary prevention.

The generalizability of the dependence syndrome across substances: an examination of some properties of the proposed DSM-IV dependence criteria.

DSM-III-R and proposed DSM-IV schemes for the diagnosis of psychoactive substance use disorders are based largely on the dependence syndrome concept. However, there is an absence of empirical support for the generalizability of the dependence syndrome across substances. This study examines how consistently proposed DSM-IV dependence criteria function to measure dependence across seven substances: alcohol, cannabis, cocaine, stimulants, hallucinogens, sedatives and opiates. Using structured research diagnostic interviews, dependence diagnoses were determined for 295 American subjects in treatment for alcohol/drug problems. Several factor analytic techniques were used to assess whether criteria formed single dimensions and how consistently individual criteria measured dependence across substances. The ability and consistency of criteria to measure a continuum of severity across substances were also assessed. Only subjects who used the substance at least six times were entered in the analyses. Overall, results provide strong support for the DSM approach for alcohol, cannabis, cocaine, stimulants, sedatives and opiates, but not for hallucinogens. Results indicate that a single strong factor adequately described the criteria for these six substances. All criteria loaded strongly and uniformly on single factors indicating that all were good measures of dependence. Criteria provided a dimensional measure of severity based on several indices for these substances. In addition, four criteria provided relatively stable indicators of high or low severity across these substances. Results did not support the use of dependence criteria for hallucinogens as these criteria did not form a single factor. Results suggest that very few hallucinogen users experience an inability to cut down or control use, a key indicator of loss of control.

Mental health nurse prescribing: issues for the UK.

Supplementary nurse prescribing holds the key to rapid developments in psychiatric nursing and the care received by patients. In this paper, the origins, context and research data on nurse prescribing are reviewed, as a backdrop to a discussion on potential application of supplementary prescribing in a number of mental health settings. We describe a number of practice settings where nurse prescribing could be implemented, and argue that given service changes and informative educational preparation, access to care and user experience of that care will be enhanced. We conclude the paper by reviewing a number of clinical, organizational and research factors important for the success of nurse prescribing.

Understanding speech in modulated interference: cochlear implant users and normal-hearing listeners.

Many competing noises in real environments are modulated or fluctuating in level. Listeners with normal hearing are able to take advantage of temporal gaps in fluctuating maskers. Listeners with sensorineural hearing loss show less benefit from modulated maskers. Cochlear implant users may be more adversely affected by modulated maskers because of their limited spectral resolution and by their reliance on envelope-based signal-processing strategies of implant processors. The current study evaluated cochlear implant users' ability to understand sentences in the presence of modulated speech-shaped noise. Normal-hearing listeners served as a comparison group. Listeners repeated IEEE sentences in quiet, steady noise, and modulated noise maskers. Maskers were presented at varying signal-to-noise ratios (SNRs) at six modulation rates varying from 1 to 32 Hz. Results suggested that normal-hearing listeners obtain significant release from masking from modulated maskers, especially at 8-Hz masker modulation frequency. In contrast, cochlear implant users experience very little release from masking from modulated maskers. The data suggest, in fact, that they may show negative effects of modulated maskers at syllabic modulation rates (2-4 Hz). Similar patterns of results were obtained from implant listeners using three different devices with different speech-processor strategies. The lack of release from masking occurs in implant listeners independent of their device characteristics, and may be attributable to the nature of implant processing strategies and/or the lack of spectral detail in processed stimuli.

Emerging technologies for HER2 testing.

HER2-positive status is the sole criterion for identifying patients with breast cancer for Herceptin therapy, which has known efficacy in women with metastatic breast cancer (MBC). Immunohistochemistry (IHC) and fluorescence in-situ hybridization (FISH), which measure the HER2 protein and gene, respectively, are currently the most widely used HER2 tests in the clinical setting. However, results from these assays are influenced by many variables including choice of antibody or probe, methodology, level of user experience and interlaboratory variability. Although there is no widespread standard testing algorithm, the importance of HER2 in clinical practice demands accurate and reproducible tests. Polymerase chain reaction (PCR) and chromogenic in-situ hybridization (CISH) represent upcoming methods for assessing HER2 gene amplification. Enzyme-linked immunosorption assay (ELISA), a semi-automated technique that can be used to measure the level of the HER2 extracellular domain (ECD) in serum, may also prove useful. While such technologies show great promise, they will at least have to be validated against IHC or FISH before being accepted into routine clinical practice.

Quitting ecstasy: an investigation of why people stop taking the drug and their subsequent mental health.

The regular use of ecstasy (3,4-methylenedioxymethamphetamine, MDMA) has been associated with depressed mood, anxiety and hostility, but it is not known whether such effects persist after people stop using the drug. Furthermore, little is known about what factors might influence the decision to quit using MDMA. The aim of the present study was to examine the reasons why ex-users had stopped using this drug and to assess their current levels of depression, anxiety, anger and aggression. Telephone interviews were conducted with people who used to take MDMA on a regular basis but who no longer used the drug. The participants comprised sixty-six ex-users who used to take MDMA regularly (at least once every 2 months over a period of at least 1 year), but who had not taken MDMA for at least 1 year (average 3 years). Participants were asked about why they had quit MDMA. They also completed questionnaires to assess trait mood. Ex-users could be divided into two groups based on their reason for quitting: (i) those who had quit for mental health reasons and (ii) those who had quit for circumstantial reasons. Approximately half of those in the mental health group scored in the range for clinical depression. In that group, current levels of depression and anxiety correlated significantly with the cumulative amount of MDMA that they had taken several years previously. These findings suggest that some users may either be more vulnerable to the adverse effects of MDMA or have pre-existing mental health problems for which they self-medicate by using ecstasy. The present study shows that some ex-users experience an impairment to mental health that persists for years after they stop using this drug.

Empowerment, policy levels and service forums.

This article will examine empowerment through policy at three levels: governmental, service and 'street'. It will focus in particular on 'street level' policy, drawing on qualitative interviews and an analysis of documentation within a day centre for adults with learning difficulties. The recorded behaviour of the workers and the structure of the day centre affected service users' experience of power. This is discussed through the theoretical construction of the organization's 'service forum' that contains its 'posture', a set of formal values and beliefs owned by the organization, and the 'culture', which is the unofficial day-to-day presentation of the service. Finally the use of such an approach is considered with regards to the future analysis of services for people with learning difficulties.

A simple method for serving Web hypermaps with dynamic database drill-down.

BACKGROUND: HealthCyberMap http://healthcybermap.semanticweb.org aims at mapping parts of health information cyberspace in novel ways to deliver a semantically superior user experience. This is achieved through "intelligent" categorisation and interactive hypermedia visualisation of health resources using metadata, clinical codes and GIS. HealthCyberMap is an ArcView 3.1 project. WebView, the Internet extension to ArcView, publishes HealthCyberMap ArcView Views as Web client-side imagemaps. The basic WebView set-up does not support any GIS database connection, and published Web maps become disconnected from the original project. A dedicated Internet map server would be the best way to serve HealthCyberMap database-driven interactive Web maps, but is an expensive and complex solution to acquire, run and maintain. This paper describes HealthCyberMap simple, low-cost method for "patching" WebView to serve hypermaps with dynamic database drill-down functionality on the Web. RESULTS: The proposed solution is currently used for publishing HealthCyberMap GIS-generated navigational information maps on the Web while maintaining their links with the underlying resource metadata base. CONCLUSION: The authors believe their map serving approach as adopted in HealthCyberMap has been very successful, especially in cases when only map attribute data change without a corresponding effect on map appearance. It should be also possible to use the same solution to publish other interactive GIS-driven maps on the Web, e.g., maps of real world health problems.

Introducing videoconferencing into educational oncopathology seminars: technical aspects, user satisfaction and open issues.

We used set-top videoconferencing equipment connected by ISDN at 384 kbit/s for six educational seminars held between the University of Udine (the local site) and the National Cancer Institute in Aviano (the remote site), 60 km away. User satisfaction was evaluated by questionnaire. The median length of seminars was 58 min (range 48-61 min), followed by a 20 min (15-26 min) discussion. Eighty-two users answered the questionnaire (a 43% response rate): 56 in Udine (a median of 11 per seminar) and 26 in Aviano (a median of 5 per seminar). Answers to the questions were similar at the two sites. Videoconferencing did not affect the users' experience of attending the seminars, as both interest and clarity were similar at the local and remote site. The results suggested that videoconferencing is a viable method for delivering seminars in oncopathology, where image quality is important.

Violence and HIV sexual risk behaviors among female sex partners of male drug users.

OBJECTIVE: Violence and HIV are emerging as interconnected public health hazards among drug users and their families. The purposes of this study are to (1) determine the prevalence of sexual and physical abuse of non-drug-using female sex partners of male drug users, and (2) ascertain the association between such violence and HIV-related risk behaviors. METHODS: From 11/93 to 11/95, 208 female sex partners of injection drug or crack users in Collier County, FL, Tucson, AZ, and Portland, OR, were interviewed as part of a NIDA-funded HIV risk reduction project. Their mean age was 30 years (range 18-54); 21% were White, 6% African American, 7% Native American, and 63% Hispanic. RESULTS: Of the 208 women, 28% reported being sexually molested and 20% raped before age 13; 41% reported being raped at least once in their lifetime. Forty-two percent of the women were physically assaulted by their sex partners; 36% had been threatened with assaulted by their sex partners. Those who were raped or threatened with assault were more likely to have multiple sex partners and engage in unprotected anal sex; there was a trend for women who had been physically assaulted to be more likely to engage in unprotected anal sex. DISCUSSION: Rape, assault and the threat of assault are commonplace in the histories of female sex partners of male drug users. Experiences of violence and threats of violence are associated with heightened risk for the sexual transmission of HIV. Providers of HIV prevention need to understand the sequelae of violence, and design interventions which empower women to protect themselves from sexual transmission of HIV.

Paper versus computer: feasibility of an electronic medical record in general pediatrics.

BACKGROUND: Implementation of electronic medical record systems promises significant advances in patient care, because such systems enhance readability, availability, and data quality. Structured data entry (SDE) applications can prompt for completeness, provide greater accuracy and better ordering for searching and retrieval, and permit validity checks for data quality monitoring, research, and especially decision support. A generic SDE application (OpenSDE) to support documentation of patient history and physical examination findings was developed and tailored for the domain of general pediatrics. OBJECTIVE: To evaluate OpenSDE for its completeness, uniformity of reporting, and usability in general pediatrics. METHODS: Four (trainee) pediatricians documented data for 8 first-visit patients in the traditional, paper-based, medical record and immediately thereafter in OpenSDE (electronic record). The 32 paper records obtained served as the common data source for data entry in OpenSDE by the other 3 physicians (transcribed record). Data entered by 2 experienced users, with all patient information present in the paper record, served as the control record. Data entry times were recorded, and a questionnaire was used to assess users' experiences with OpenSDE. RESULTS: Clinicians documented 44% of all available patient information identically in the paper and electronic records. Twenty-five percent of all patient information was documented only in the paper record, and 31% was present only in the electronic record. Differences were found in patient history and physical examination documentation in the electronic record; more information was missing for patient history (38%) than for physical examination (15%). Furthermore, physical examination contained more additional information (39%) than did patient history (21%). The interobserver agreement of documentation of patient information from the same data source was fair to moderate, with kappa values of 0.39 for patient history and 0.40 for physical examination. Data entry times in OpenSDE decreased from 25 minutes to <15 minutes, indicating a learning effect. The questionnaire revealed a positive attitude toward the use of OpenSDE in daily practice. CONCLUSION: OpenSDE seems to be a promising application for the support of physician data entry in general pediatrics.

Cost-Effectiveness of Electronic Patient-Reported Outcome Measure Interventions in Cancer: Systematic Review and Parameter Extraction for Economic Modeling.

BACKGROUND: Complex digital interventions that integrate electronic patient-reported outcome measures (ePROM) into clinical practice in cancer have the potential to improve quality of life, increase survival, and reduce health resource use and costs. Such systems can help patients with cancer self-manage chemotherapy symptoms, reduce clinicians' workloads through automated decision support, and resolve problems earlier. However, more research on the cost-effectiveness of ePROM monitoring is needed. OBJECTIVE: This paper comprises two complementary components: (1) a systematic literature review summarizing and evaluating the quantitative and qualitative evidence related to the cost-effectiveness of ePROM monitoring and (2) a health economic model parameter extraction. We also conducted supplementary targeted searches and scoping to provide context to our findings. METHODS: We searched Ovid (including MEDLINE and Embase), Scopus, and the International Health Technology Assessment Database for original English-language papers published on or before March 2025 using search strings that combined terms related to ePROMs, health economics, and cancer/oncology. We included papers reporting health economic-related outcomes for ePROM interventions designed for adult cancer populations and excluded screening tools and conference abstracts. RESULTS: We included 34 publications from 27 unique studies and identified and analyzed 26 ePROM-integrated interventions within these. Most (23/26) of the included interventions explicitly described some form of alert handling and automated decision support based on remote ePROM monitoring. Of the 34 publications, 5 presented full cost-effectiveness analysis results, of which 3 were highly uncertain and lacked clear differences in costs and health outcomes between ePROMs and standard care; conversely, 2 presented strong evidence of cost-effectiveness due to quality-of-life improvements, reduced hospitalizations, and potentially more autonomy in health-related travel (eg, ePROM-monitored patients can drive or walk to the hospital instead of using taxis or ambulances). A further 5 publications reported partial health economic results (eg, cost-consequence and budget impact), of which 1 detected no difference in strategies; in contrast, 4 reported lower health resource use and costs of ePROMs, mainly due to hospitalization reductions. Overall, 12 of the 27 studies included a qualitative component but mostly focused on user experience and design-related themes; only 2 of these addressed economic-specific themes (eg, changes in workflow and resource use due to ePROM implementation and integration), indicating some potential for time saving due to ePROM monitoring. CONCLUSIONS: Some ePROM-integrated interventions demonstrated cost-effectiveness in cancer care, but the evidence base remains limited. Where evidence does exist, cost-effectiveness appears driven by reduced hospitalization and improved quality of life. Qualitative research within the included studies rarely addressed economic questions. We provide a detailed parameter extraction for use in future economic modeling and recommend research priorities, including quantitative mapping of ePROM symptom data onto health resource use patterns, and qualitative work exploring how ePROM implementation affects clinical workloads and patient-perspective costs.

Searching for cancer information on the internet: analyzing natural language search queries.

BACKGROUND: Searching for health information is one of the most-common tasks performed by Internet users. Many users begin searching on popular search engines rather than on prominent health information sites. We know that many visitors to our (National Cancer Institute) Web site, cancer.gov, arrive via links in search engine result. OBJECTIVE: To learn more about the specific needs of our general-public users, we wanted to understand what lay users really wanted to know about cancer, how they phrased their questions, and how much detail they used. METHODS: The National Cancer Institute partnered with AskJeeves, Inc to develop a methodology to capture, sample, and analyze 3 months of cancer-related queries on the Ask.com Web site, a prominent United States consumer search engine, which receives over 35 million queries per week. Using a benchmark set of 500 terms and word roots supplied by the National Cancer Institute, AskJeeves identified a test sample of cancer queries for 1 week in August 2001. From these 500 terms only 37 appeared >or= 5 times/day over the trial test week in 17208 queries. Using these 37 terms, 204165 instances of cancer queries were found in the Ask.com query logs for the actual test period of June-August 2001. Of these, 7500 individual user questions were randomly selected for detailed analysis and assigned to appropriate categories. The exact language of sample queries is presented. RESULTS: Considering multiples of the same questions, the sample of 7500 individual user queries represented 76077 queries (37% of the total 3-month pool). Overall 78.37% of sampled Cancer queries asked about 14 specific cancer types. Within each cancer type, queries were sorted into appropriate subcategories including at least the following: General Information, Symptoms, Diagnosis and Testing, Treatment, Statistics, Definition, and Cause/Risk/Link. The most-common specific cancer types mentioned in queries were Digestive/Gastrointestinal/Bowel (15.0%), Breast (11.7%), Skin (11.3%), and Genitourinary (10.5%). Additional subcategories of queries about specific cancer types varied, depending on user input. Queries that were not specific to a cancer type were also tracked and categorized. CONCLUSIONS: Natural-language searching affords users the opportunity to fully express their information needs and can aid users naïve to the content and vocabulary. The specific queries analyzed for this study reflect news and research studies reported during the study dates and would surely change with different study dates. Analyzing queries from search engines represents one way of knowing what kinds of content to provide to users of a given Web site. Users ask questions using whole sentences and keywords, often misspelling words. Providing the option for natural-language searching does not obviate the need for good information architecture, usability engineering, and user testing in order to optimize user experience.

Methamphetamine abuse: a perfect storm of complications.

Previously restricted primarily to Hawaii and California, methamphetamine abuse has reached epidemic proportions throughout the United States during the past decade, specifically in rural and semirural areas. Particular characteristics of methamphetamine production and use create conditions for a "perfect storm" of medical and social complications. Unlike imported recreational drugs such as heroin and cocaine, methamphetamine can be manufactured locally from commonly available household ingredients according to simple recipes readily available on the Internet. Methamphetamine users and producers are frequently one and the same, resulting in both physical and environmental consequences. Users experience emergent, acute, subacute, and chronic injuries to neurologic, cardiac, pulmonary, dental, and other systems. Producers can sustain life-threatening injuries in the frequent fires and explosions that result when volatile chemicals are combined. Partners and children of producers, as well as unsuspecting first responders to a crisis, are exposed to toxic by-products of methamphetamine manufacture that contaminate the places that serve simultaneously as "lab" and home. From the vantage point of a local emergency department, this article reviews the range of medical and social consequences that radiate from a single hypothetical methamphetamine-associated incident.

Public reporting of hospital outcomes based on administrative data: risks and opportunities.

In the wake of findings from the Bundaberg Hospital and Forster inquiries in Queensland, periodic public release of hospital performance reports has been recommended. A process for developing and releasing such reports is being established by Queensland Health, overseen by an independent expert panel. This recommendation presupposes that public reports based on routinely collected administrative data are accurate; that the public can access, correctly interpret and act upon report contents; that reports motivate hospital clinicians and managers to improve quality of care; and that there are no unintended adverse effects of public reporting. Available research suggests that primary data sources are often inaccurate and incomplete, that reports have low predictive value in detecting "outlier" hospitals, and that users experience difficulty in accessing and interpreting reports and tend to distrust their findings.

A hospital-wide forms management program: doing more for less.

The day-to-day management of the hospital forms business can be time-consuming, frustrating, and expensive. In many cases, the official inventory represents only a fraction of the total number of forms used throughout an institution. Since the responsibility for inventory and quality control becomes diffuse, forms users experience frequent stockouts and poorly designed forms. Without a centralized program, it is difficult to determine the costs associated with forms. An effective forms management program can be designed to fulfill most everyone's needs. The program described in this article incorporates the concept of stockless purchasing to gain better quality forms at significant cost savings.
