1.  Knowledge about Obstetric Danger Signs and Associated Factors among Mothers in Tsegedie District, Tigray Region, Ethiopia 2013: Community Based Cross-Sectional Study 
PLoS ONE  2014;9(2):e83459.
Background
In many developing countries including Ethiopia, maternal morbidity and mortality still pose a substantial burden and thus progress towards the fifth Millennium Development Goal (MDG) remains slow. Raising awareness of women about the danger signs of pregnancy and childbirth is the first essential step in accepting appropriate and timely referral to obstetric care. However, in Ethiopia little is known about the knowledge level of mothers about obstetric danger signs. The objective of this study was to assess the status of knowledge of danger signs of pregnancy and childbirth among mothers who gave birth in the past two years prior to the survey in Tsegedie district, Tigray regional state, Ethiopia.
Methods
A Community based cross-sectional study was conducted from November 20, 2012 to June 30, 2013 on a randomly selected sample of 485 women who had at least one delivery in the past two years. Multistage sampling technique was employed to select the study participants. A pre-tested structured questionnaire was used to collect quantitative data. Focus group discussion and in-depth interviews were utilized to supplement the Quantitative data. Bivariate and multivariate data analysis was performed using SPSS version 17.0 software.
Result
Four hundred eighty five mothers participated in the study making a response rate of 100%. Vaginal bleeding was the most commonly mentioned danger signs of pregnancy (49.1%) and childbirth (52.8%). Two hundred eighty five (58.8%) and 299 (61.6%) of respondents mentioned at least two danger signs of pregnancy and childbirth respectively. One hundred seventy (35.1%) and 154 (31.8%) of respondents didn't know any danger signs of pregnancy and childbirth respectively. Educational status of the mother, place of delivery and having functional radio were found to be independent predictors of knowledge of women about the danger signs of pregnancy and childbirth.
Conclusion
Educational status of the mother, place of delivery and having functional radio were independently associated with knowledge of women about obstetric danger signs. Thus, provision of information, education and communication targeting women, family and the general community on danger signs of pregnancy and childbirth and associated factors was recommended.

2.  A program for increasing manual signing by autistic and profoundly retarded youth within the daily environment 
A program was implemented to increase the manual signing of five profoundly retarded and four autistic youth within their daily environment. Each participant was nonvocal or minimally vocal. The program was based on modified incidental teaching strategies and was implemented by direct care personnel under supervision in an institutional setting. Specific components included rearranging the physical environment to prompt signing, altering routine staff-resident interactions to prompt, manually guide and/or reinforce signing; and conducting mini-training sessions. Additionally, staff modeled signs intermittently throughout the day. The program was sequentially implemented during two staff work shifts on each of two resident living modules. Observations conducted at four separate time periods during the day indicated that significant increases in signing occurred for all participating youth and that the increases generally maintained during follow-up checks at 5 and 17 weeks. Differential effects of the increased signing on frequency of vocalizations were noted across residents. A staff acceptability survey indicated favorable staff reports on the usefulness of signing to communicate with the youth. Results are discussed regarding the significance of manual signing for seriously developmentally disabled persons and the importance of ensuring that signing skills are used in the daily environment and not exclusively in formal training sessions. Also, areas for continued research are noted in terms of more refined analyses of client skills and subsequent progress in manual communication programs.

3.  The quality–coverage gap in antenatal care: toward better measurement of effective coverage 
The proportion of pregnant women receiving 4 or more antenatal care (ANC) visits has no necessary relationship with the actual content of those visits. We propose a simple alternative to measure program performance that aggregates key services that are common across countries and measured in Demographic and Health Surveys, such as blood pressure measurement, tetanus toxoid vaccination, first ANC visit before 4 months gestation, urine testing, counseling about pregnancy danger signs, and iron–folate supplementation.
The proportion of pregnant women receiving 4 or more antenatal care (ANC) visits has no necessary relationship with the actual content of those visits. We propose a simple alternative to measure program performance that aggregates key services that are common across countries and measured in Demographic and Health Surveys, such as blood pressure measurement, tetanus toxoid vaccination, first ANC visit before 4 months gestation, urine testing, counseling about pregnancy danger signs, and iron–folate supplementation.
Background:
The proportion of pregnant women receiving 4 or more antenatal care visits (ANC 4+) is used prominently as a global benchmark indicator to track maternal health program performance. This has contributed to an inappropriate focus on the number of contacts rather than on the content and process of care. This paper presents analysis of specific elements of care received among women reporting 4 or more ANC visits.
Methods:
We conducted secondary analysis using Demographic and Health Survey data from 41 countries to determine coverage for specific elements of antenatal care. The analysis was conducted for: (1) women who delivered during the 2 years preceding the survey and who reported receiving 4 or more ANC visits, and (2) all women who delivered during the preceding 2 years. The specific ANC services that we assessed were: blood pressure measurement, tetanus toxoid vaccination, first ANC visit at less than 4 months gestation, urine testing, counseling about danger signs, HIV counseling and testing, iron–folate supplementation (≥ 90 days), and at least 2 doses of sulfadoxine/pyramethamine for malaria prevention. The difference between expected (100%) and actual coverage (the quality–coverage gap) was calculated for each service across the 41 surveys.
Results:
Coverage for specific elements of care among women reporting 4 or more ANC visits was generally low for most of the specific elements assessed. Blood pressure and tetanus toxoid performed best, with median quality–coverage gaps of 5% and 18%, respectively. The greatest gaps were for iron–folate supplementation (72%) and malaria prevention (86%). Coverage for specific interventions was generally much lower among all pregnant women (reflecting population effective coverage) than among only those who had received ANC 4+ visits. Although ANC 4+ and average coverage across the elements of care correlated relatively well (Pearson r2  =  0.56), most countries had lower average coverage for the content of care than for ANC 4+ (among all pregnant women).
Conclusion:
We argue for the adoption of a summary indicator that better reflects the content of antenatal care than does the current ANC 4+ indicator. We propose, as an alternative, the simple average of a set of ANC content indicators available through surveys and routine health information systems.

4.  Using vital signs to assess children with acute infections: a survey of current practice 
Background
GPs are advised to measure vital signs in children presenting with acute infections. Current evidence supports the value of GPs' overall assessment in determining how unwell a child is, but the additional benefit of measuring vital signs is not known.
Aim
To describe the vital signs and clinical features that GPs use to assess children (aged <5 years) with acute infections.
Design of study
Questionnaire survey.
Setting
All 210 GP principals working within a 10 mile radius of Oxford, UK.
Method
Data were collected on reported frequency, methods, and utility of measuring vital signs. Description of clinical features was used to assess the overall severity of illness.
Results
One hundred and sixty-two (77%) GPs responded. Half (54%, 95% confidence interval [CI] = 47 to 62) measured temperature at least weekly, compared to pulse (21%, 95% CI = 15 to 27), and respiratory rates (17%, 95% CI = 11 to 23). Almost half of GPs (77, 48%) never measured capillary refill time. Temperature was measured most frequently using electronic aural thermometers (131/152; 86%); auscultation or counting were used for pulse and respiratory rates. A minority used pulse oximeters to assess respiratory status (30/151, 20%). GPs' thresholds for tachypnoea were similar to published values, but there was no consensus on the threshold of tachycardia. Observations of behaviour and activity were considered more useful than vital signs in assessing severity of illness.
Conclusion
Vital signs are uncommonly measured in children in general practice and are considered less useful than observation in assessing the severity of illness. If measurement of vital signs is to become part of standard practice, the issues of inaccurate measurement and diagnostic value need to be addressed urgently.

5.  Web Evaluation at the US National Institutes of Health: Use of the American Customer Satisfaction Index Online Customer Survey 
Background
The National Institutes of Health (NIH), US Department of Health and Human Services (HHS), realized the need to better understand its Web users in order to help assure that websites are user friendly and well designed for effective information dissemination. A trans-NIH group proposed a trans-NIH project to implement an online customer survey, known as the American Customer Satisfaction Index (ACSI) survey, on a large number of NIH websites—the first “enterprise-wide” ACSI application, and probably the largest enterprise Web evaluation of any kind, in the US government. The proposal was funded by the NIH Evaluation Set-Aside Program for two years at a cost of US $1.5 million (US $1.275 million for survey licenses for 60 websites at US $18,000 per website; US $225,000 for a project evaluation contractor).
Objective
The overall project objectives were to assess the value added to the participating NIH websites of using the ACSI online survey, identify any NIH-wide benefits (and limitations) of the ACSI, ascertain any new understanding about the NIH Web presence based on ACSI survey results, and evaluate the effectiveness of a trans-NIH approach to Web evaluation. This was not an experimental study and was not intended to evaluate the ACSI survey methodology, per se, or the impacts of its use on customer satisfaction with NIH websites.
Methods
The evaluation methodology included baseline pre-project websites profiles; before and after email surveys of participating website teams; interviews with a representative cross-section of website staff; observations of debriefing meetings with website teams; observations at quarterly trans-NIH Web staff meetings and biweekly trans-NIH leadership team meetings; and review and analysis of secondary data.
Results
Of the original 60 NIH websites signed up, 55 implemented the ACSI survey, 42 generated sufficient data for formal reporting of survey results for their sites, and 51 completed the final project survey. A broad cross-section of websites participated, and a majority reported significant benefits and new knowledge gained from the ACSI survey results. NIH websites as a group scored consistently higher on overall customer satisfaction relative to US government-wide and private sector benchmarks.
Conclusions
Overall, the enterprise-wide experiment was successful. On the level of individual websites, the project confirmed the value of online customer surveys as a Web evaluation method. The evaluation results indicated that successful use of the ACSI, whether site-by-site or enterprise-wide, depends in large part on strong staff and management support and adequate funding and time for the use of such evaluative methods. In the age of Web-based e-government, a broad commitment to Web evaluation may well be needed. This commitment would help assure that the potential of the Web and other information technologies to improve customer and citizen satisfaction is fully realized.

6.  Use of an Appreciative Inquiry Approach to Improve Resident Sign-Out in an Era of Multiple Shift Changes 
ABSTRACT
BACKGROUND
Resident duty hour restrictions have resulted in more frequent patient care handoffs, increasing the need for improved quality of residents’ sign-out process.
OBJECTIVE
To characterize resident sign-out process and identify effective strategies for quality improvement.
DESIGN
Mixed methods analysis of resident sign-out, including a survey of resident views, prospective observation and characterization of 64 consecutive sign-out sessions, and an appreciative-inquiry approach for quality improvement.
PARTICIPANTS
Internal medicine residents (n = 89).
INTERVENTIONS
An appreciative inquiry process identified five exemplar residents and their peers’ effective sign-out strategies.
MAIN MEASURES
Surveys were analyzed and observations of sign-out sessions were characterized for duration and content. Common effective strategies were identified from the five exemplar residents using an appreciative inquiry approach.
KEY RESULTS
The survey identified wide variations in the methodology of sign-out. Few residents reported that laboratory tests (13%) or medications (16%) were frequently accurate. The duration of observed sign-outs averaged 134 ±73 s per patient for the day shift (6 p.m.) sign-out compared with 59 ± 41 s for the subsequent night shift (8 p.m.) sign-out for the same patients (p = 0.0002). Active problems (89% vs 98%, p = 0.013), treatment plans (52% vs 73%, p = 0.004), and laboratory test results (56% vs 80%, p = 0.002) were discussed less commonly during night compared with day sign-out. The five residents voted best at sign-out (mean vote 11 ± 1.6 vs 1.7 ± 2.3) identified strategies for sign-out: (1) discussing acutely ill patients first, (2) minimizing discussion on straightforward patients, (3) limiting plans to active issues, (4) using a systematic approach, and (5) limiting error-prone chart duplication.
CONCLUSIONS
Resident views toward sign-out are diverse, and accuracy of written records may be limited. Consecutive sign-outs are associated with degradation of information. An appreciative-inquiry approach capitalizing on exemplar residents was effective at creating standards for sign-out.

7.  Rural Community Knowledge of Stroke Warning Signs and Risk Factors 
Preventing Chronic Disease  2005;2(2):A14.
Introduction
Rapid identification and treatment of ischemic stroke can lead to improved patient outcomes. Public education campaigns in selected communities have helped to increase knowledge about stroke, but most data represent large metropolitan centers working with academic institutions. Much less is known about knowledge of stroke among residents in rural communities.
Methods
In 2004, 800 adults aged 45 years and older from two Montana counties participated in a telephone survey using unaided questions to assess awareness of stroke warning signs and risk factors. The survey also asked respondents if they had a history of atrial fibrillation, diabetes, high blood pressure, high cholesterol, smoking, heart disease, or stroke.
Results
More than 70% of survey participants were able to correctly report two or more warning signs for stroke: numbness on any side of the face/body (45%) and speech difficulties (38%) were reported most frequently. More than 45% were able to correctly report two or more stroke risk factors: smoking (50%) and high blood pressure (44%) were reported most frequently. Respondents aged 45 to 64 years (odds ratio [OR] 2.44; 95% confidence interval [CI], 1.78–3.46), women (OR 2.02; 95% CI, 1.46–2.80), those with 12 or more years of education (OR 1.96; 95% CI, 1.08–3.56), and those with high cholesterol (OR 1.68; 95% CI, 1.17–2.42) were more likely to correctly identify two or more warning signs compared with respondents without these characteristics. Women (OR 1.48; 95% CI, 1.07–2.05) and respondents aged 45 to 64 years (OR 1.35; 95% CI, 1.01–1.81) were also more likely to correctly identify two or more stroke risk factors compared with men and older respondents.
Conclusion
Residents of two rural counties were generally aware of stroke warning signs, but their knowledge of stroke risk factors was limited.

8.  Canine angiostrongylosis in Italy: occurrence of Angiostrongylus vasorum in dogs with compatible clinical pictures 
Parasitology Research  2013;112(7):2473-2480.
This study evaluated the perception of veterinarians in including the emerging metastrongyloid Angiostrongylus vasorum in the differential diagnosis for dogs referred with appropriate signs. Veterinarians at teaching hospitals, private practices or kennels collected faecal samples from 606 symptomatic dogs in six different areas of Italy. The samples were examined with the Baermann technique. Fourteen dogs scored positive for A. vasorum, all showing different clinical pictures, with the most common reason for inclusion in the study being a combination of respiratory signs along with general signs. The most reported sign was cough, followed by aspecific distresses. Other respiratory signs were dyspnoea, tachypnoea and breathing sounds, while bleeding diathesis occurred in one dog. Gastrointestinal disorders were diarrhoea and vomitus, while no neurological signs were detected. Four key cases are herein described, with a special focus on their clinical description, findings at the collateral diagnostic imaging and therapeutic options with moxidectin. This survey provides new data on distribution of A. vasorum in Europe and on the clinical impact of the disease. The results confirm that clinical angiostrongylosis overlaps a series of other conditions of dogs. Awareness among vet practitioners is discussed along with the importance of including A. vasorum on the list of differential diagnoses in canine clinical practice and of performing appropriate diagnostic methods.

9.  Clinical signs of early osteoarthritis: reproducibility and relation to x ray changes in 541 women in the general population. 
Annals of the Rheumatic Diseases  1991;50(7):467-470.
The definition and classification of early clinically apparent osteoarthritis both in clinical situations and in epidemiological surveys remains a problem. Few data exist on the between-observer reproducibility of simple clinical methods of detecting hand and knee osteoarthritis in the population and their sensitivity and specificity as compared with radiography. Two observers first studied the reproducibility of a number of clinical signs in 41 middle aged women. Good rates of agreement were found for most of the clinical signs tested (kappa = 0.54-1.0). The more reproducible signs were then tested on a population of 541 women, aged 45-65, drawn from general practice, screening centres, and patients previously attending hospital for non-rheumatic problems. The major clinical signs used had a high specificity (87-99%) and lower sensitivity (20-49%) when compared with radiographs graded on the Kellgren and Lawrence scale (2+ = positive). When analysis was restricted to symptomatic radiographic osteoarthritis, levels of sensitivity were increased and specificity was lowered. These data show that certain physical signs of osteoarthritis are reproducible and may be used to identify clinical disease. They are not a substitute for radiographs, however, if radiographic change is regarded as the 'gold standard' of diagnosis. As the clinical signs tested seemed specific for osteoarthritis they may be of value in screening populations for clinical disease.

10.  Knowledge of Risk Factors and Warning Signs of Stroke 
In this review, we have summarized the findings of fifteen studies of knowledge of stroke warning signs and risk factors in both high- and low-risk populations. In general, there appears to be low levels of knowledge of both risk factors and stroke warning signs among the communities studied. Using free recall, between 20% and 30% of respondents could not name a single risk factor, and between 10% and 60% could not name a single warning sign of stroke. Providing survey respondents with a list of potential warning signs substantially improved the identification of warning signs. Respondents in older age groups and having lower levels of educational attainment tended to have less knowledge of risk factors and warning signs of stroke than those in younger age groups and those with more education. Public campaigns to improve stroke knowledge are needed, particularly in the older age groups where the risk of stroke is greater.

11.  A Comparative Analysis of 2 National Breast Reconstruction Surveys: Concerns Regarding Autologous and Microsurgical Breast Reconstruction 
Background:
Pertinent findings of two national breast reconstruction (BR) surveys from two different institutions at two separate times (2012 vs 2010) were analyzed for comparison.
Methods:
An appraisal of sampling methodology, sample demographics, years of practice, practice affiliation, BR type, and annual volume between the two studies was conducted using statistical analysis.
Results:
Proper sampling technique and adequate sample size were used in both surveys to represent the typical population of general US plastic surgeons practicing BR. There were no differences in mean age or years of practice between the sample population in both studies. The percentage of plastic surgeons with academic affiliation was higher in the 2012 survey compared to the 2010 survey (28% vs 18%, P<0.05). Implant-based BR was the predominant method among surveyed plastic surgeons in both surveys. There was a substantial decrease in the proportion of plastic surgeons performing >20 cases per year in the 2012 survey compared to the 2010 survey (P<0.05). A high volume of BR, defined as >60 cases per year in the 2010 survey and >20 cases per year in the 2012 survey, correlated significantly with academic practice and multidisciplinary cancer centers, respectively (P<0.05). There was a significant decline in the percentage of plastic surgeons performing microsurgical BR from 2010 to 2012 (35% vs 25%, P<0.05).
Conclusions:
Comparative data suggest that there are fewer high volume BR cases being performed by US plastic surgeons and that there has been a reduction among plastic surgeons in the use of microsurgical BR from 2010 to 2012. We believe that these findings may indicate early signs of the changes in BR trends in the US.

12.  Integrated Mapping of Neglected Tropical Diseases: Epidemiological Findings and Control Implications for Northern Bahr-el-Ghazal State, Southern Sudan 
Background
There are few detailed data on the geographic distribution of most neglected tropical diseases (NTDs) in post-conflict Southern Sudan. To guide intervention by the recently established national programme for integrated NTD control, we conducted an integrated prevalence survey for schistosomiasis, soil-transmitted helminth (STH) infection, lymphatic filariasis (LF), and loiasis in Northern Bahr-el-Ghazal State. Our aim was to establish which communities require mass drug administration (MDA) with preventive chemotherapy (PCT), rather than to provide precise estimates of infection prevalence.
Methods and Findings
The integrated survey design used anecdotal reports of LF and proximity to water bodies (for schistosomiasis) to guide selection of survey sites. In total, 86 communities were surveyed for schistosomiasis and STH; 43 of these were also surveyed for LF and loiasis. From these, 4834 urine samples were tested for blood in urine using Hemastix reagent strips, 4438 stool samples were analyzed using the Kato-Katz technique, and 5254 blood samples were tested for circulating Wuchereria bancrofti antigen using immunochromatographic card tests (ICT). 4461 individuals were interviewed regarding a history of ‘eye worm’ (a proxy measure for loiasis) and 31 village chiefs were interviewed regarding the presence of clinical manifestations of LF in their community. At the village level, prevalence of Schistosoma haematobium and S. mansoni ranged from 0 to 65.6% and from 0 to 9.3%, respectively. The main STH species was hookworm, ranging from 0 to 70% by village. Infection with LF and loiasis was extremely rare, with only four individuals testing positive or reporting symptoms, respectively. Questionnaire data on clinical signs of LF did not provide a reliable indication of endemicity. MDA intervention thresholds recommended by the World Health Organization were only exceeded for urinary schistosomiasis and hookworm in a few, yet distinct, communities.
Conclusion
This was the first attempt to use an integrated survey design for this group of infections and to generate detailed results to guide their control over a large area of Southern Sudan. The approach proved practical, but could be further simplified to reduce field work and costs. The results show that only a few areas need to be targeted with MDA of PCT, thus confirming the importance of detailed mapping for cost-effective control.
Author Summary
Integrated control of neglected tropical diseases (NTDs) is being scaled up in a number of developing countries, because it is thought to be more cost-effective than stand-alone control programmes. Under this approach, treatments for onchocerciasis, lymphatic filariasis (LF), schistosomiasis, soil-transmitted helminth (STH) infection, and trachoma are administered through the same delivery structure and at about the same time. A pre-requisite for implementation of integrated NTD control is information on where the targeted diseases are endemic and to what extent they overlap. This information is generated through surveys that can be labour-intensive and expensive. In Southern Sudan, all of the above diseases except onchocerciasis require further mapping before a comprehensive integrated NTD control programme can be implemented. To determine where treatment for which disease is required, integrated surveys were conducted for schistosomiasis, STH infection, LF, and loiasis, throughout one of ten states of the country. Our results show that treatment is only required for urinary schistosomiasis and STH in a few, yet separate, geographical area. This illustrates the importance of investing in disease mapping to minimize overall programme costs by being able to target interventions. Integration of survey methodologies for the above disease was practical and efficient, and minimized the effort required to collect these data.

13.  Prevalence of Trachoma in Unity State, South Sudan: Results from a Large-Scale Population-Based Survey and Potential Implications for Further Surveys 
Background
Large parts of South Sudan are thought to be trachoma-endemic but baseline data are limited. This study aimed to estimate prevalence for planning trachoma interventions in Unity State, to identify risk factors and to investigate the effect of different sampling approaches on study conclusions.
Methods and Findings
The survey area was defined as one domain of eight counties in Unity State. Across the area, 40 clusters (villages) were randomly selected proportional to the county population size in a population-based prevalence survey. The simplified grading scheme was used to classify clinical signs of trachoma. The unadjusted prevalence of trachoma inflammation-follicular (TF) in children aged 1–9 years was 70.5% (95% CI: 68.6–72.3). After adjusting for age, sex, county and clustering of cases at household and village level the prevalence was 71.0% (95% CI: 69.9–72.1). The prevalence of trachomatous trichiasis (TT) in adults was 15.1% (95% CI: 13.4–17.0) and 13.5% (95% CI: 12.0–15.1) before and after adjustment, respectively. We estimate that 700,000 people (the entire population of Unity State) require antibiotic treatment and approximately 54,178 people require TT surgery. Risk factor analyses confirmed child-level associations with TF and highlighted that older adults living in poverty are at higher risk of TT. Conditional simulations, testing the alternatives of sampling 20 or 60 villages over the same area, indicated that sampling of only 20 villages would have provided an acceptable level of precision for state-level prevalence estimation to inform intervention decisions in this hyperendemic setting.
Conclusion
Trachoma poses an enormous burden on the population of Unity State. Comprehensive control is urgently required to avoid preventable blindness and should be initiated across the state now. In other parts of South Sudan suspected to be highly trachoma endemic, counties should be combined into larger survey areas to generate the baseline data required to initiate interventions.
Author Summary
Large parts of South Sudan are thought to be trachoma endemic but baseline data, required to initiate interventions, are few. District-by-district surveys, currently recommended by the World Health Organization (WHO), are often not financially or logistically viable. We therefore adapted existing WHO guidelines and combined eight counties (equivalent to districts) of Unity State into one survey area, randomly sampling 40 villages using a population-based survey design. This decision was based on a trachoma risk map and a trachoma rapid assessment, both identifying the state as likely to be highly endemic. The survey confirmed trachoma as being hyperendemic throughout Unity State, meaning that large-scale intervention should be initiated now. Simulation studies were conducted to determine the likely outcome if fewer (n = 20) or more (n = 60) villages had been sampled, confirming that precision decreased or increased, respectively. Importantly, simulation results also showed that all three sample sizes would have led to the same conclusion, namely the need for large-scale intervention. This finding suggests that district-by-district surveys may not be required for areas where trachoma is suspected to be highly prevalent but that are lacking baseline data; instead districts may be combined into a larger survey area.

14.  Defining Childhood Severe Falciparum Malaria for Intervention Studies 
PLoS Medicine  2007;4(8):e251.
Background
Clinical trials of interventions designed to prevent severe falciparum malaria in children require a clear endpoint. The internationally accepted definition of severe malaria is sensitive, and appropriate for clinical purposes. However, this definition includes individuals with severe nonmalarial disease and coincident parasitaemia, so may lack specificity in vaccine trials. Although there is no “gold standard” individual test for severe malaria, malaria-attributable fractions (MAFs) can be estimated among groups of children using a logistic model, which we use to test the suitability of various case definitions as trial endpoints.
Methods and Findings
A total of 4,583 blood samples were taken from well children in cross-sectional surveys and from 1,361 children admitted to a Kenyan District hospital with severe disease. Among children under 2 y old with severe disease and over 2,500 parasites per microliter of blood, the MAFs were above 85% in moderate- and low-transmission areas, but only 61% in a high-transmission area. HIV and malnutrition were not associated with reduced MAFs, but gastroenteritis with severe dehydration (defined by reduced skin turgor), lower respiratory tract infection (clinician's final diagnosis), meningitis (on cerebrospinal fluid [CSF] examination), and bacteraemia were associated with reduced MAFs. The overall MAF was 85% (95% confidence interval [CI] 83.8%–86.1%) without excluding these conditions, 89% (95% CI 88.4%–90.2%) after exclusions, and 95% (95% CI 94.0%–95.5%) when a threshold of 2,500 parasites/μl was also applied. Applying a threshold and exclusion criteria reduced sensitivity to 80% (95% CI 77%–83%).
Conclusions
The specificity of a case definition for severe malaria is improved by applying a parasite density threshold and by excluding children with meningitis, lower respiratory tract infection (clinician's diagnosis), bacteraemia, and gastroenteritis with severe dehydration, but not by excluding children with HIV or malnutrition.
The accepted definition of severe malaria is appropriate for clinical purposes, but Philip Bejon and colleagues show its specificity in clinical trials may be improved by a parasite density threshold and by excluding children with certain conditions.
Editors' Summary
Background.
Malaria is responsible for over a million deaths every year, and most of those who die are children in Africa. Until a few years ago, not enough research was being done on malaria, but now many researchers are active in this field. Doctors describe some cases of malaria as being “severe.” Severe malaria in children is very hard to diagnose precisely. Current protocols for diagnosing severe malaria are very sensitive: that is, virtually all children who do have severe malaria will be correctly diagnosed as such. However, the protocols are not very specific: many children who do not have severe malaria, but whose symptoms are instead caused by other diseases, will be defined as suffering from severe malaria. This definition is acceptable for the clinical care of sick children, because it ensures that antimalarial drugs are given to all who might benefit from them, plus some additional children for whom those drugs are not required. However, this definition is not particularly useful for research purposes. When conducting a clinical trial aimed at preventing cases of malaria, it is important to evaluate whether the intervention being tested actually works. Therefore, a more specific method of calculating the number of malaria cases within a population is needed for this type of research.
Why Was This Study Done?
The current definition for diagnosing severe malaria includes a set of signs and symptoms that may be observed at the bedside or as a result of laboratory investigation, along with the detection of malaria parasites in the patient's blood. However, in many malarious areas, a large proportion of the population carries malaria parasites without signs of disease; at the same time, the signs and symptoms of malaria are shared with other diseases. The investigators here wanted to find out whether they could develop an accurate “case definition” of severe malaria that can be used in research.
What Did the Researchers Do and Find?
In this study, two groups of children were studied: first, 1,422 children admitted to the children's wards of the Kilifi District Hospital in Kenya, and second, 4,583 children from the surrounding community. Blood samples were taken in order to find out how common malaria parasites were in the children's blood, and standard clinical and laboratory data were also collected from the children admitted to the hospital. The researchers then compared these data using a computer and tried to find out whether, by excluding certain children who had particular signs, symptoms, or observations, from the diagnosis of severe malaria, they were able to improve the accuracy of their definition. Essentially, for each patient group, the authors calculated “malaria-attributable fractions,” i.e., the proportion of individuals studied whose disease was likely caused by malaria.
The researchers found that in areas with low and moderate transmission of malaria, the proportion of individuals whose disease could be attributed to malaria was high—nearly 85%. In areas with a high transmission rate of malaria, this fraction was much lower, but could be improved by including only children with a high proportion of parasites in their blood. Importantly, the researchers were also able to increase the recognition of children with disease likely caused by malaria by excluding individuals who had also been diagnosed with gastroenteritis, lower respiratory tract infections, meningitis, and bacterial infection in the blood. If all of these individuals were excluded—so only individuals with more than 2,500 parasites per microliter in their blood were regarded as having severe malaria—the “malaria-attributable fraction” rose to 95%.
What Do These Findings Mean?
These findings should not be directly used to change the clinical care of children with the signs and symptoms of severe malaria, but rather can be used within a clinical trial to create a “case definition” of malaria particular to that trial. This ability will help researchers more accurately find out whether the intervention being tested in their trial really does help to prevent cases of malaria or not.

15.  Lungworm (Crenosoma vulpis) infection in dogs on Prince Edward Island. 
The Canadian Veterinary Journal  1999;40(8):555-559.
Crenosoma vulpis is a nematode lungworm that is highly prevalent in the red fox population of Atlantic Canada. Dogs are susceptible to infection with clinical signs consisting primarily of a chronic cough. A recent report of C. vulpis infection in 3 dogs on Prince Edward Island prompted an investigation into the importance of this parasite as a cause of chronic respiratory disease in Island dogs. A general prevalence was determined through the necropsy of dogs euthanized at the local humane society. Lungs were removed and examined for parasites using a lung flush technique. Rectal feces was collected and examined for first-stage larvae using the Baermann technique and zinc sulfate centrifugal flotation. Ten of 310 dogs (3.2%) were positive with 0-35 worms (mean = 11.0 +/- 13.4) recovered. First-stage larvae of C. vulpis were recovered in the rectal feces of the one animal in which no worms were recovered on lung flush. A second survey was conducted examining fecal samples with the Baermann technique from afebrile dogs with presenting signs of chronic cough that had no history of recent anthelmintic treatment and showed no signs of cardiac disease, based on physical examination. Fifteen of 55 dogs examined (27.3%) were definitively diagnosed as C. vulpis-positive. All of the infected dogs were treated with fenbendazole (50 mg/kg body weight, p.o. q24 h for 3-7 days). Clinical signs resolved in all of the dogs and fecal samples were negative 2-4 weeks posttreatment. It was concluded that C. vulpis infection was a significant cause of upper respiratory disease in dogs on Prince Edward Island and should be considered in all dogs with presenting signs of chronic cough.

16.  Self-reported awareness of the presence of product warning messages and signs by Hispanics in San Francisco. 
Public Health Reports  1994;109(2):275-283.
This study investigated the self-reported awareness of the presence of product warning messages and signs among random samples of Hispanics in San Francisco surveyed in 1990 and in 1991. The messages that were tested related to cigarettes, alcoholic beverages, and other consumer products. A random sample of 1,204 Hispanics (43.5 percent males) were interviewed by telephone in 1990. The corresponding figure for the second survey in 1991 was 1,569 Hispanics (41.1 percent males). In general, respondents reported low levels of awareness of the presence of product warning messages and signs. The exception was warning messages on cigarette packets which approximately 70 percent of the respondents reported having seen within the 12 months before the survey. There was an increase from 1990 to 1991 in the reported awareness of warning messages for wine, beer, and cigarettes. Smokers and drinkers of alcoholic beverages reported the highest levels of awareness of the relevant warning messages and signs. Length of exposure to warning messages and multiplicity of sources (for example, advertisements and products) seem to produce greater levels of awareness of the presence of product warning messages. Less acculturated, Spanish-speaking Hispanics are less likely to report being aware of the warnings, particularly those that appear only in English (for example, alcoholic beverages).

17.  New monoclonal anti-mouse DC-SIGN antibodies reactive with acetone-fixed cells 
Journal of immunological methods  2010;360(1-2):66-75.
Mouse DC-SIGN CD209a is a type II transmembrane protein, one of a family of C-type lectin genes syntenic and homologous to human DC-SIGN. Current anti-mouse DC-SIGN monoclonal antibodies (MAbs) are unable to react with DC-SIGN in acetone fixed cells, limiting the chance to visualize DC-SIGN in tissue sections. We first produced rabbit polyclonal PAb-DSCYT14 against a 14-aa peptide in the cytosolic domain of mouse DC-SIGN, and it specifically detected DC-SIGN and not the related lectins, SIGN-R1 and SIGN-R3 expressed in transfected CHO cells. MAbs were generated by immunizing rats and DC-SIGN knockout mice with the extracellular region of mouse DC-SIGN.. Five rat IgG2a or IgM MAbs, named BMD10, 11, 24, 25, and 30, were selected and each MAb specifically detected DC-SIGN by FACS and Western blots, although BMD25 was cross-reactive to SIGN-R1. Two mouse IgG2c MAbs MMD2 and MMD3 interestingly bound mouse DC-SIGN but at 10 fold higher levels than the rat MAbs. When the binding epitopes of the new BMD and two other commercial rat anti-DC-SIGN MAbs, 5H10 and LWC06, were examined by competition assays, the epitopes of BMD11, 24, and LWC06 were identical or closely overlapping while BMD10, 30, and 5H10 were shown to bind different epitopes. MMD2 and MMD3 epitopes were on a 3rd noncompeting region of mouse DC-SIGN. DC-SIGN expressed on the cell surface was sensitive to collagenase treatment, as monitored by polyclonal and MAb. These new reagents should be helpful to probe the biology of DC-SIGN in vivo.

18.  Broad Reach and Targeted Recruitment Using Facebook for an Online Survey of Young Adult Substance Use 
Background
Studies of tobacco use and other health behaviors have reported great challenges in recruiting young adults. Social media is widely used by young adults in the United States and represents a potentially fast, affordable method of recruiting study participants for survey research.
Objective
The present study examined Facebook as a mechanism to reach and survey young adults about tobacco and other substance use.
Methods
Participants were cigarette users, age 18-25 years old, living throughout the United States and recruited through Facebook to complete a survey about tobacco and other substance use. Paid advertising using Facebook’s Ad program over 13 months from 2010 Feb 28 to 2011 Apr 4 targeted by age (18-25), location (United States or California), language (English), and tobacco- and/or marijuana-related keywords. Facebook approved all ads.
Results
The campaign used 20 ads, which generated 28,683,151 impressions, yielding 14,808 clicks (0.7% of targeted Facebook members), at an overall cost of $6,628.24. The average cost per click on an ad was $0.45. The success of individual ads varied widely. There was a rise in both clicks and impressions as the campaign grew. However, the peak for clicks was 3 months before the peak for ad impressions. Of the 69,937,080 accounts for those age 18-25 in the United States, Facebook estimated that 2.8% (n = 1,980,240) were reached through tobacco and marijuana keywords. Our campaign yielded 5237 signed consents (35.4% of clicks), of which 3093 (59%) met criteria, and 1548 (50% of those who met criteria) completed the survey. The final cost per valid completed survey was $4.28. The majority of completed surveys came from whites (69%) and males (72%). The sample averaged 8.9 cigarettes per day (SD 7.5), 3.8 years of smoking (SD 2.9), with a median of 1 lifetime quit attempts; 48% did not intend to quit smoking in the next 6 months.
Conclusions
Despite wide variety in the success of individual ads and potential concerns about sample representativeness, Facebook was a useful, cost-effective recruitment source for young-adult smokers to complete a survey about the use of tobacco and other substances. The current findings support Facebook as a viable recruitment option for assessment of health behavior in young adults.

19.  Reporting Guidelines for Survey Research: An Analysis of Published Guidance and Reporting Practices 
PLoS Medicine  2011;8(8):e1001069.
Carol Bennett and colleagues review the evidence and find that there is limited guidance and no consensus on the optimal reporting of survey research.
Background
Research needs to be reported transparently so readers can critically assess the strengths and weaknesses of the design, conduct, and analysis of studies. Reporting guidelines have been developed to inform reporting for a variety of study designs. The objective of this study was to identify whether there is a need to develop a reporting guideline for survey research.
Methods and Findings
We conducted a three-part project: (1) a systematic review of the literature (including “Instructions to Authors” from the top five journals of 33 medical specialties and top 15 general and internal medicine journals) to identify guidance for reporting survey research; (2) a systematic review of evidence on the quality of reporting of surveys; and (3) a review of reporting of key quality criteria for survey research in 117 recently published reports of self-administered surveys. Fewer than 7% of medical journals (n = 165) provided guidance to authors on survey research despite a majority having published survey-based studies in recent years. We identified four published checklists for conducting or reporting survey research, none of which were validated. We identified eight previous reviews of survey reporting quality, which focused on issues of non-response and accessibility of questionnaires. Our own review of 117 published survey studies revealed that many items were poorly reported: few studies provided the survey or core questions (35%), reported the validity or reliability of the instrument (19%), defined the response rate (25%), discussed the representativeness of the sample (11%), or identified how missing data were handled (11%).
Conclusions
There is limited guidance and no consensus regarding the optimal reporting of survey research. The majority of key reporting criteria are poorly reported in peer-reviewed survey research articles. Our findings highlight the need for clear and consistent reporting guidelines specific to survey research.

Editors' Summary
Background
Surveys, or questionnaires, are an essential component of many types of research, including health, and usually gather information by asking a sample of people questions on a specific topic and then generalizing the results to a larger population. Surveys are especially important when addressing topics that are difficult to assess using other approaches and usually rely on self reporting, for example self-reported behaviors, such as eating habits, satisfaction, beliefs, knowledge, attitudes, opinions. However, the methods used in conducting survey research can significantly affect the reliability, validity, and generalizability of study results, and without clear reporting of the methods used in surveys, it is difficult or impossible to assess these characteristics and therefore to have confidence in the findings.
Why Was This Study Done?
This uncertainty in other forms of research has given rise to Reporting Guidelines—evidence-based, validated tools that aim to improve the reporting quality of health research. The STROBE (STrengthening the Reporting of OBservational studies in Epidemiology) Statement includes cross-sectional studies, which often involve surveys. But not all surveys are epidemiological, and STROBE does not include methods' and results' reporting characteristics that are unique to surveys. Therefore, the researchers conducted this study to help determine whether there is a need for a reporting guideline for health survey research.
What Did the Researchers Do and Find?
The researchers identified any previous relevant guidance for survey research, and any evidence on the quality of reporting of survey research, by: reviewing current guidance for reporting survey research in the “Instructions to Authors” of leading medical journals and in published literature; conducting a systematic review of evidence on the quality of reporting of surveys; identifying key quality criteria for the conduct of survey research; and finally, reviewing how these criteria are currently reported by conducting a review of recently published reports of self-administered surveys.
The researchers found that 154 of the 165 journals searched (93.3%) did not provide any guidance on survey reporting, even though the majority (81.8%) have published survey research. Only three of the 11 journals that provided some guidance gave more than one directive or statement. Five papers and one Internet site provided guidance on the reporting of survey research, but none used validated measures or explicit methods for development. The researchers identified eight papers that addressed the quality of reporting of some aspect of survey research: the reporting of response rates; the reporting of non-response analyses in survey research; and the degree to which authors make their survey instrument available to readers. In their review of 117 published survey studies, the researchers found that many items were poorly reported: few studies provided the survey or core questions (35%), reported the validity or reliability of the instrument (19%), discussed the representativeness of the sample (11%), or identified how missing data were handled (11%). Furthermore, (88 [75%]) did not include any information on consent procedures for research participants, and one-third (40 [34%]) of papers did not report whether the study had received research ethics board review.
What Do These Findings Mean?
Overall, these results show that guidance is limited and consensus lacking about the optimal reporting of survey research, and they highlight the need for a well-developed reporting guideline specifically for survey research—possibly an extension of the guideline for observational studies in epidemiology (STROBE)—that will provide the structure to ensure more complete reporting and allow clearer review and interpretation of the results from surveys.

20.  PERCEPTION OF FEMALE STUDENTS OF KING SAUD UNIVERSITY TOWARDS PREMARITAL SCREENING 
Objectives:
The aim of this study was to investigate the perception of King Saud University female students towards the implementation of premarital screening (PMS) in the Kingdom of Saudi Arabia (KSA).
Methods:
Two consecutive surveys on knowledge, attitudes and practice (KAP) were conducted two and nine months after the compulsory implementation of PMS in KSA in 1/1/1425H. The female students of King Saud University were given health education lectures before the survey. The first survey was done with a designed close-ended questionnaire distributed at pre and post stages of the health education lecture. However, the second one explored the participants’ perception of the same items in open-ended questions summarized as a “consensus statement”. In fulfillment of their demands, the signed statement was mailed to the legislative authorities.
Results and discussion:
A total of 140 university female students attended the first lecture. The response rate for both pre and post lecture surveys were 132 (94.3%) and 128 (91.4%) respectively. A total of 112 out of 132 (84.8%) students in the pre test and 111 out of 128 (86.7%) in the post-test were single.
Of the married students 7/20 (35.0%) and 7/17 (41.2%) in pre and post tests had previously had PMS screening. The attitude of the students towards PMS was generally positive. One hundred and eight (81.8%) in the pre test and 110 (85.9%) in the post test saw the importance of PMS in controlling the commonest hereditary diseases. However, a smaller percentage of students (69.7% and 75.0%) in pre and post lecture respectively were in favor of the compulsory application of PMS in KSA. In spite of the positive attitude of all the students in the pre and post tests, fears were expressed towards the confidentiality of PMS test results and it was felt that social and psychological problems would ensue from abnormal results. This, however, does not represent the feeling of the entire population in KSA since the participants of the study formed a select group.
The second awareness lecture was attended by 319 students from the College of Education. They were subsequently requested to state their perceptions of PMS application with regard to its content, nature and method of application in KSA in their own words. The collected forms were summarized into a “consensus statement” and signed by all 319 students. They felt that the scope of PMS should be extended to investigate and screen for other diseases especially sexually transmitted diseases that would adversely affect the health of members of the family and the community as a whole. Their worry about the lack of screening for other diseases may be because a majority of the study group were single and would, therefore, refuse to get married on account of the risks to their future offspring. In addition, it may reflect their knowledge of the effects of globalization on the transmission of diseases.
Conclusions:
Health education is an important means of improving the public's perception of newly-introduced health interventions. University students have a good perception of the compulsory implementation of PMS in KSA. Pre-marital screening could be extended to include a broader spectrum of health/genetic disorders and will be useful for early identification and possible intervention as well as the prevention of complications.

21.  Updated canine infection rates for Dirofilaria immitis in areas of Brazil previously identified as having a high incidence of heartworm-infected dogs 
Parasites & Vectors  2014;7(1):493.
Background
Canine heartworm infections were frequently diagnosed in Brazil before the new millennium. After the year 2000, the frequency of diagnosis showed a sharp decline; however, a few years later, new evidence indicated that the parasite was still present and that canine infection rates seemed to be increasing. Therefore, an updated survey of canine heartworm prevalence was conducted in several locations in south, southeast, and northeast Brazil.
Methods
Dogs from 15 locations having previously reported a high prevalence of heartworm infection were included in the survey according to defined criteria, including the absence of treatment with a macrocyclic lactone for at least 1 year. Blood samples from 1531 dogs were evaluated by an in-clinic immunochromatography test kit (Witness® Heartworm, Zoetis, USA) for detection of Dirofilaria immitis antigen. At each location, epidemiologic data, including physical characteristics and clinical signs reported by owners or observed by veterinarians, were recorded on prepared forms for tabulation of results by location, clinical signs, and physical characteristics.
Results
The overall prevalence of canine heartworm infection was 23.1%, with evidence of heartworm-infected dogs detected in all 15 locations studied. There was a tendency for higher prevalence rates in environmentally protected areas, despite some locations having less-than-ideal environmental temperatures for survival of vector mosquitoes. Among physical characteristics, it was noted that dogs with predominantly white hair coats and residing in areas with a high (≥20%) prevalence of heartworm were less likely to have heartworm infection detected by a commercial heartworm antigen test kit than were dogs with other coat colors. In general, dogs older than 2 years were more frequently positive for D. immitis antigen than were younger dogs. Clinical signs of heartworm infections were rare or owners were unable to detect them, and could not be used for reliable prediction of the presence of heartworm.
Conclusions
These results indicate that the prevalence of D. immitis has increased in these areas of Brazil over the past few years. Small animal practitioners in these areas should include routine screening tests for heartworm infections in every dog’s annual evaluation protocol and make sure to have uninfected dogs on prevention.

22.  Expanding access to coronary artery bypass surgery: who stands to gain? 
British Heart Journal  1995;73(2):129-133.
OBJECTIVE--To determine the perceptions of general practitioners (GPs) about the benefits of coronary artery bypass surgery, in terms of gains in life expectancy, for different groups of patients. DESIGN--A questionnaire survey of all GPs in Northern Ireland. SETTING--A survey conducted collaboratively by the departments of public health medicine in each of the four health boards in the province, serving a total population of 1.5 million. MAIN OUTCOME MEASURES--The median and mean gain in life expectancy perceived by groups of doctors for smoking and non-smoking male and female 55 year old patients. The percentage of 50 year old and 70 year old non-smoking patients considered likely to have their lives extended with bypass surgery. Differences were assessed using the Mann-Whitney U test for unpaired samples and the Wilcoxon signed rank tests for paired. RESULTS--541 GPs replied (response rate 56%). The median (and mean) perceived gain in life expectancy after cardiac surgery for non-smoking 55 year old subjects was 120 (104) months for men and 120 (112) months for women (z = 6.42; P < 0.0001; Wilcoxon signed rank test). For male and female smokers of the same age, the perceived gains were 48 (47) and 60 (52) months respectively (z = 6.72; P < 0.0001; Wilcoxon signed ranks test), both figures being significantly different than for non-smokers. The median (and mean) percentage of patients that the doctors considered would have their lives extended by bypass surgery was 70 (64) of every 100 "young" patients and 40 (42) of every 100 "old" patients, (z = 16.2; P < 0.0001). CONCLUSIONS--These results point to a significant overestimation of the benefits of coronary artery bypass surgery by GPs in Northern Ireland and to a need to develop guidelines for referral.

23.  Evaluation of an Asynchronous Physician Voice Mail Sign-out for Emergency Department Admissions 
Annals of emergency medicine  2009;54(3):368-378.
Background
Communication failures contribute to errors in the transfer of patients from the emergency department (ED) to inpatient medicine units. Oral (synchronous) communication has numerous benefits but is costly and time-consuming. Taped (asynchronous) communication may be more reliable and efficient, but lacks interaction. We evaluated a new asynchronous physician-physician sign-out compared to the traditional synchronous sign-out.
Methods
A voicemail-based, semi-structured sign-out for routine ED admissions to internal medicine was implemented in October, 2007 at an urban, academic medical center. Outcomes were obtained by pre- and post-intervention surveys of ED and IM housestaff, physician assistants and hospitalist attendings; and by examination of access logs and administrative data. Outcome measures included utilization; physician perceptions of ease, accuracy, content, interaction and errors; and rate of transfers to intensive care from the floor within 24 hours of ED admission. Results were analyzed both quantitatively, and qualitatively using standard qualitative analytic techniques.
Results
During September-October, 2008 (one year post-intervention), voicemails were recorded regarding 90.5% of medicine admissions; 69.7% of these were accessed at least once by admitting physicians. The median length of each sign-out was 2.6 minutes (IQR 1.9 to 3.5). We received 117/197 responses (59%) to the pre-intervention survey and 113/206 responses (55%) to the post-intervention survey. A total of 73/101 (72%) respondents reported dictated sign-out was easier than oral sign-out and 43/101 (43%) reported it was more accurate. However, 70/101 (69%) reported interaction among participants was worse. There was no change in the rate of ICU transfer within 24 hours of admission from the ED in April-June, 2007 (65/6,147; 1.1%) versus April-June 2008 (70/6,263; 1.1%); difference of 0%, 95% CI, −0.4% to 0.3%. The proportion of internists reporting at least one perceived adverse event relating to transfer from the ED decreased a non-significant 10% after the intervention (95% CI, −27% to 6%), from 44% pre-intervention (32/72) to 34% post-intervention (23/67).
Conclusion
Voicemail sign-out for ED-internal medicine communication was easier than oral sign-out without any change in early ICU transfers or the perception of major adverse events. However, interaction among participants was reduced. Voicemail sign-out may be an efficient means of improving sign-out communication for stable ED admissions.

24.  Extending role by Japanese pharmacists after training for performing vital signs monitoring 
Pharmacy Practice  2014;12(3):442.
Background
In Japan, the circumstances in which pharmacists work are changing. Pharmacists are expected to assess conditions of patients subject to medication to ensure proper use of pharmaceutical products. To ensure fulfilment of these roles, there have already been pharmacists’ efforts in performing vital signs monitoring.
Objective
To clarify the necessity and related issues, by investigating the state of vital sign monitoring in clinical field by pharmacists who have been trained in vital sign monitoring.
Method
A web survey was conducted from 4th October to 3rd December 2012, subjecting 1,026 pharmacists who completed the vital signs training hosted by The Japanese Association of Home Care Pharmacies (JAHCP). Survey items were 1) basic information of a respondent, 2) situation of homecare conducted by pharmacists, 3) seminar attendance status, and 4) vital signs monitoring status after the seminar.
Results
The number of valid respondents was 430 and the response rate was 41.9%. As a result of the present research, it was revealed that 168 pharmacists (41.4%), had the opportunity to perform vital signs monitoring. By conducting vital sign monitoring, effects such as 1) improved motivation of pharmacists and better communication with patients, 2) proper use of medication, and 3) cost reduction were confirmed.
Conclusion
Judging from the results of the survey, pharmacists can improve medication therapy for patients by attaining vital sign skills and conduct vital sign monitoring. Pharmacists who perform vital sign monitoring should share cases where they experienced positive patient outcomes.

25.  Functional Evaluation of DC-SIGN Monoclonal Antibodies Reveals DC-SIGN Interactions with ICAM-3 Do Not Promote Human Immunodeficiency Virus Type 1 Transmission 
Journal of Virology  2002;76(12):5905-5914.
DC-SIGN, a type II membrane-spanning C-type lectin that is expressed on the surface of dendritic cells (DC), captures and promotes human and simian immunodeficiency virus (HIV and SIV) infection of CD4+ T cells in trans. To better understand the mechanism of DC-SIGN-mediated virus transmission, we generated and functionally evaluated a panel of seven monoclonal antibodies (MAbs) against DC-SIGN family molecules. Six of the MAbs reacted with myeloid-lineage DC, whereas one MAb preferentially bound DC-SIGNR/L-SIGN, a homolog of DC-SIGN. Characterization of hematopoietic cells also revealed that stimulation of monocytes with interleukin-4 (IL-4) or IL-13 was sufficient to induce expression of DC-SIGN. All DC-SIGN-reactive MAbs competed with intercellular adhesion molecule 3 (ICAM-3) for adhesion to DC-SIGN and blocked HIV-1 transmission to T cells that was mediated by THP-1 cells expressing DC-SIGN. Similar but less efficient MAb blocking of DC-mediated HIV-1 transmission was observed, indicating that HIV-1 transmission to target cells via DC may not be dependent solely on DC-SIGN. Attempts to neutralize DC-SIGN capture and transmission of HIV-1 with soluble ICAM-3 prophylaxis were limited in success, with a maximal inhibition of 60%. In addition, disrupting DC-SIGN/ICAM-3 interactions between cells with MAbs did not impair DC-SIGN-mediated HIV-1 transmission. Finally, forced expression of ICAM-3 on target cells did not increase their susceptibility to HIV-1 transmission mediated by DC-SIGN. While these findings do not discount the role of intercellular contact in facilitating HIV-1 transmission, our in vitro data indicate that DC-SIGN interactions with ICAM-3 do not promote DC-SIGN-mediated virus transmission.
