Background

Although being an important source of science news information to the public, print news media have often been criticized in their credibility. Health-related content of press media articles has been examined by many studies underlining that information about benefits, risks and costs are often incomplete or inadequate and financial conflicts of interest are rarely reported. However, these studies have focused their analysis on very selected science articles. The present research aimed at adopting a wider explorative approach, by analysing all types of health science information appearing on the Italian national press in one-week period. Moreover, we attempted to score the balance of the articles.

Methodology/Principal Findings

We collected 146 health science communication articles defined as articles aiming at improving the reader''s knowledge on health from a scientific perspective. Articles were evaluated by 3 independent physicians with respect to different divulgation parameters: benefits, costs, risks, sources of information, disclosure of financial conflicts of interest and balance. Balance was evaluated with regard to exaggerated or non correct claims. The selected articles appeared on 41 Italian national daily newspapers and 41 weekly magazines, representing 89% of national circulation copies: 97 articles (66%) covered common medical treatments or basic scientific research and 49 (34%) were about new medical treatments, procedures, tests or products. We found that only 6/49 (12%) articles on new treatments, procedures, tests or products mentioned costs or risks to patients. Moreover, benefits were always maximized and in 16/49 cases (33%) they were presented in relative rather than absolute terms. The majority of stories (133/146, 91%) did not report any financial conflict of interest. Among these, 15 were shown to underreport them (15/146, 9.5%), as we demonstrated that conflicts of interest did actually exist. Unbalanced articles were 27/146 (18%). Specifically, the probability of unbalanced reporting was significantly increased in stories about a new treatment, procedure, test or product (22/49, 45%), compared to stories covering common treatments or basic scientific research (5/97, 5%) (risk ratio, 8.72).

Conclusions/Significance

Consistent with prior research on health science communication in other countries, we report undisclosed costs and risks, emphasized benefits, unrevealed financial conflicts of interest and exaggerated claims in Italian print media. In addition, we show that the risk for a story about a new medical approach to be unbalanced is almost 9 times higher with respect to stories about any other kind of health science-related topics. These findings raise again the fundamental issue whether popular media is detrimental rather than useful to public health.  相似文献

OBJECTIVE--To study the coverage of the chronic fatigue syndrome in the popular and professional press. DESIGN--Search of all original research papers on the chronic fatigue syndrome published in British journals from 1980 onwards and of professional trade papers, national newspapers, and women''s magazines. Interviews with six medical journalists. SETTING--British scientific, medical, and popular press. RESULTS--37 (49%) articles in research journals did not favour organic causes and 23 (31%) favoured organic causes. By contrast 31 (55%) articles in the medical trade press and 118 (69%) in national newspapers and women''s magazines favoured organic causes. CONCLUSIONS--Press coverage of chronic fatigue syndrome has amplified and distorted divisions in the research community concerning the chronic fatigue syndrome. Articles in the press concentrate on a simple medical model of illness reinforcing the stigma of psychological illness and dissatisfaction with traditional medical authority.  相似文献

Literature on spot-billed pelican has not been reviewed lately which could provide a critique of the emerging data. We have now chosen it as a key species through which we suggest a conservation action plan which will benefit several waterbird species. The information provided here is scholastic in nature and is meant to focus on aspects that require attention and help plan future work for applied conservation. All known information on this species is brought together in this review which will also provide an update of its biology. Notes on the breeding biology of the species first published in the Journal of the Bombay Natural History Society. So far, 380 works have appeared on the species; of these, 36 contain material reported in earlier works or appeared as papers subsequently. Most appeared as articles in journals, both national and regional, a few international journals, newsletters/bulletins (48.2%), 4 dissertations, 76 reports and 6 popular science articles in magazines. This review on the species will provide an insight into different factors that can be weighed and combined while making a decision in investing resources in species conservation, i.e. importance of the species, level of threat and the time frame over which results are to be achieved.  相似文献

BACKGROUND: Medical advice columns in newspapers can provide a valuable service by educating the general public about important health-related issues. However, these columns may be harmful if the advice or information given in them is incomplete, inappropriate or misleading. The objective of this study was to assess the safety and appropriateness of advice given to elderly readers of newspapers in medical advice columns. METHODS: Medical advice columns published in Canadian newspapers in 1995 were identified from a CD-ROM database. The articles that were selected were published in English and contained medical advice pertinent to elderly people about topics that could be found in a textbook of geriatric medicine. Fifty articles, randomly selected from the 109 articles that met these criteria, were independently assessed by 5 geriatricians. A scoring system was used to rate the ability to determine to which population the article applied, how well fact was distinguished from opinion, the degree to which critical issues were addressed, the safety and the appropriateness of the advice. When the kappa statistic for inter-rater agreement was 0.74 or less, a 2-stage Delphi process was used in an attempt to reach consensus. RESULTS: Agreement (kappa > 0.74) was eventually achieved for 232 (92.8%) of the 250 ratings. In 4 (8%) of the articles there was a high probability that the advice given could be applied to the wrong patient population; in 7 (14%) there was a high probability that opinion might be interpreted as fact; and in 11 (22%) the major critical issues were not identified. Of greatest concern, however, the advice in 25 (50%) of the articles was judged to be inappropriate, and in 14 (28%) advice may have been dangerous and potentially life-threatening. INTERPRETATION: Although medical advice columns have the potential to improve the health of elderly readers, a significant percentage of these articles contain inappropriate or even potentially dangerous advice.  相似文献

Abstract

This paper characterizes the portrayal of animals and human-animal relations in one genre of American popular culture—the “supermarket” tabloid press. A total of 789 animal-related stories and photographs in 82 issues of four tabloid magazines were analyzed according to theme. The items fell into nine categories in which animals were portrayed as objects of affection, saviors, threats, victims, things to be used, sex objects, imaginary and mythological beings, surrogate humans, and objects of wonder. It is argued that these themes represent archetypes reflecting the roles that animals have had in human cultural and psychological life since the historical origins of our species.  相似文献

Odds ratios (ORs) are widely used in scientific research to demonstrate the associations between outcome variables and covariates (risk factors) of interest, and are often described in language suitable for risks or probabilities, but odds and probabilities are related, not equivalent. In situations where the outcome is not rare (e.g., obesity), ORs no longer approximate the relative risk ratio (RR) and may be misinterpreted. Our study examines the extent of misinterpretation of ORs in Obesity and International Journal of Obesity. We reviewed all 2010 issues of these journals to identify all articles that presented ORs. Included articles were then primarily reviewed for correct presentation and interpretation of ORs; and secondarily reviewed for article characteristics that may have been associated with how ORs are presented and interpreted. Of the 855 articles examined, 62 (7.3%) presented ORs. ORs were presented incorrectly in 23.2% of these articles. Clinical articles were more likely to present ORs correctly than social science or basic science articles. Studies with outcome variables that had higher relative prevalence were less likely to present ORs correctly. Overall, almost one-quarter of the studies presenting ORs in two leading journals on obesity misinterpreted them. Furthermore, even when researchers present ORs correctly, the lay media may misinterpret them as relative RRs. Therefore, we suggest that when the magnitude of associations is of interest, researchers should carefully and accurately present interpretable measures of association--including RRs and risk differences--to minimize confusion and misrepresentation of research results.  相似文献

Background

Authors of randomized trial reports seem to hold a variety of views regarding the relationship between missing outcome data (MOD) and intention to treat (ITT). The objectives of this study were to systematically investigate how authors of methodology articles define ITT in the presence of MOD, how they recommend handling MOD under ITT, and to make a proposal for potential improvement in the definition and use of ITT in relation to MOD.

Methods and Findings

We systematically searched MEDLINE in February 2009 for methodological articles written in English that devoted at least one paragraph to ITT and two other paragraphs to either ITT or MOD. We excluded original trial reports, observational studies, and clinical systematic reviews. Working in teams of two, we independently extracted relevant information from each eligible article. Of 1007 titles and abstracts reviewed, 66 articles met eligibility criteria. Five (8%) did not provide a definition of ITT; 25 (38%) mentioned MOD but did not discuss its relationship to ITT; and 36 (55%) discussed the relationship of MOD with ITT. These 36 articles described one or more of three statements: complete follow-up is required for ITT (58%); ITT and MOD are separate issues (17%); and ITT requires a specific strategy for handling MOD (78%); 17 (47%) endorsed more than one relationship. The most frequently mentioned strategies for handling MOD within ITT were: using the last outcome carried forward (50%); sensitivity analysis (50%); and use of available data to impute missing data (46%).

Conclusion

We found that there is no consensus on the definition of ITT in relation to MOD. For conceptual clarity, we suggest that both reports of randomized trials and systematic reviews separately consider and describe how they deal with participants with complete data and those with MOD.  相似文献

BACKGROUND: Concern has been expressed that women are not adequately represented in clinical trials evaluating treatments for medical conditions they commonly experience. This study was designed to assess the reporting of data on women in recently published trials of drug therapy for myocardial infarction, including those funded by an agency with a gender-related policy. METHODS: All randomized controlled trials and meta-analyses of drug therapies for myocardial infarction published in The New England Journal of Medicine, The Lancet, The Journal of the American Medical Association, the Annals of Internal Medicine and the British Medical Journal from January 1992 to December 1996 were evaluated. On preliminary review 102 articles met the inclusion criteria; these were reviewed in detail, and 59 were excluded. Two reviewers independently extracted gender-related information from the 43 articles; discrepancies were resolved by consensus. RESULTS: Women presented up to 48% of the trial participants (mean 24.1%). In the trials funded by an agency with a gender-related policy, only 16.8% of participants, on average, were women. Of the 43 articles in the sample, only 14 (32%) provided gender-related results. Funding from an agency with gender-related policy did not affect the reporting of gender-related information. Subgroup analyses were provided for 14 (32%) of the 43 trials, including 2 (29%) of 7 trials funded by an agency with a gender-related policy. Of the 12 trials that included interaction analyses (excluding the 2 trials in which secondary analyses were conducted specifically to identify differences between women and men), 7 (58%) conducted an interaction analysis to determine if women responded differently than men; for one of these the interaction analysis was for a secondary outcome measure (drug safety). Only 5 (12%) of the 43 articles mentioned the differences between men and women in the Discussion section; 2 of these were studies that used secondary analyses to examine sex differences. Of the 5, only 1 was funded by an agency with a gender-related policy. INTERPRETATION: Women were poorly represented in the randomized controlled trials in this sample, regardless of whether the trials were funded by an agency with a gender-related policy. Structured reporting of gender-related information for clinical trials may improve the quality of information available about women and therefore facilitate the application of research findings to the care of women.  相似文献

Climate change and human development are altering aquatic thermal regimes, highlighting the need to understand how fish fitness may be impacted across a generational boundary. We reviewed experimental temperature studies investigating the links between parents and progeny, asking questions regarding the taxa studied, broodfish used, offspring traits examined, experimental durations and research motivations. We identified forty-one peer-reviewed articles examining the effects of pre-spawning adult temperature holding on offspring. These studies showed a strong focus on the order Salmoniformes (46% of studies) and aquaculturally driven research (66%). The use of wild broodfish was rare (12%) and the majority of experiments (83%) did not examine offspring consequences beyond hatch. We also identified 56 articles investigating how incubation temperature and parental influences affect embryonic and larval development. We demonstrate that these studies are not common in comparison to the majority of incubation thermal experiments that do not employ controlled parental breeding designs. However, 52 out of 56 studies we reviewed reported maternal, paternal or family identity influenced offspring responses to temperature. In characterizing these studies, Salmoniformes were the most studied order (52%), wild broodfish were more commonly used (55%), aquaculture motivations were less evident (23%), and few studies investigated offspring performance or traits beyond endogenous yolk stages. Overall, we suggest it is beneficial to experimentally examine temperature with consideration to parent-progeny relationships. To broaden our current understanding of intergenerational temperature effects, we recommend an increased focus on wild populations, offspring physiological and performance measures, later offspring development stages, and expanding research in non-salmonid species.  相似文献

During early pregnancy,an orchestrated evolutionary maternal adaption toward tolerance of the semiallogeneic fetus is required to ensure decidualization and early embryo development.Remodeling of the immune system involves natural killer cells(NKs),macrophages,T cells and dendritic cells(DCs) altering the microenvironment in the deciduas.In particular,a unique population of NK cells with a CD56~(bright)CD16~- phenotype in the decidua has been proposed to play a key role in the maternal adaptation to pregnancy.However,there is a tendency for pregnancy immunology to reflect transplantation immunology regarding the assumption that the maternal immune system should be suppressed.This tendency is misleading.We discuss how the immune system is formed in early deciduas and the interactions between maternal NK cells and fetal growth.We propose that the maternal immune response must not be fully suppressed and is even necessary for the local response of uterine NK cells.  相似文献

BACKGROUND: Most clinicians read only the abstract of papers in scientific journals. Therefore, it is very important that abstracts contain as much information as possible, to summarize the data succinctly. Our objectives were to evaluate the quality of information in abstracts reporting human fetal outcomes following drug exposure during pregnancy. METHODS: We developed quality criteria based on previous work, modifying them for use with pregnancy outcomes. Quality scores were calculated as present/absent for all of the equally weighted criteria, then expressed as percentages (present/[present + absent]). We examined a random sample of 100 abstracts obtained through searches of MEDLINE, EMBASE, and the Web of Science databases from 1990 to 2005. Average quality scores were compared across designs (cohort, case-control, meta-analysis, and mixed design) Using Kruskal-Wallis ANOVA and structured/unstructured formats using Student's t test. RESULTS: The overall average quality was 59.2% +/- 14% (median, 61.5%; range, 15.4-83.3%). Quality was not significantly different across designs (P = .16) or between structured and unstructured abstracts (P = .44). Quality scores increased over time (Rho = 0.23, P = .02). Most frequently absent were baseline risk (94%), drug dose (91%), nonsignificant P values (72%), confounders (69%), significant P values (57%), and risk difference (48%). CONCLUSIONS: Abstracts provide insufficient information, particularly baseline risk values, for readers to make evidence-based decisions regarding drug use during pregnancy. Efforts need to be made to improve the quality of abstracts and include critical information such as baseline risk.  相似文献

In this article, we describe a simplified approach to teach students to assess information obtained from diverse sources. Three broad categories (credibility, content, and currency; 3C) were used to evaluate information from textbooks, monographs, popular magazines, scholarly journals, and the World Wide Web. This 3C approach used in an inquiry course for freshmen in an undergraduate science program can be readily transferred to other settings.  相似文献

ObjectiveTo review the literature regarding the use of insulin glargine during pregnancy, specifically addressing the issues and concerns surrounding mitogenicity, placental transfer, and maternal and fetal safety.MethodsWe performed a systematic literature search using MEDLINE and BIOSIS Previews up to March 2011. Additional studies were identified by hand-searching reference lists from original articles. Inclusion was limited to studies and abstracts in the English language.ResultsA total of 23 reports with 1001 pregnancies managed with insulin glargine contained relevant information regarding the maternal and fetal safety of its use during pregnancy. Insulin glargine does not appear to have enhanced mitogenic activity when compared with the mitogenic activity of native human insulin. The transplacental transfer of insulin glargine appears to be negligible, although it is possible that antibody-bound insulin glargine may gain access to the fetal compartment. The available data suggest that there are no identifiable, consistent adverse maternal or fetal outcomes with the use of insulin glargine during pregnancy, including during the first trimester.ConclusionsUse of insulin glargine during pregnancy should be seriously considered in uncontrolled diabetes during pregnancy and in those patients taking insulin glargine before conception, because the benefits from improved glycemic control would be expected to outweigh any, as yet, unproven risks of insulin glargine exposure.(Endocr Pract. 2011;17:448-455)  相似文献

OBJECTIVE: To determine the present role of general practitioners (GPs) in the delivery of surgical and anesthesia services in rural western Canada. DESIGN: Survey by mailed questionnaire in November 1993, with telephone follow-up of nonresponders. SETTING: Rural British Columbia, Alberta, the Yukon Territory and the Northwest Territories. PARTICIPANTS: Administrators of 148 rural hospitals; of the 121 who completed it 101 represented hospitals that met the inclusion criteria (fewer than 51 beds and serving a population of 15,000 or less). OUTCOME MEASURES: Hospital characteristics, type of practitioners providing surgical and anesthesia services, length and location of GPs'', surgical and anesthesia training, types of surgical procedures performed by GPs and opinions of administrators regarding the delivery of surgical services in their community. RESULTS: Surgical services were provided by 56 (55%) of the 101 hospitals; at 45 (80%) they were provided by GPs, and at 33 (59%) they were provided by GPs with limited additional surgical training. Fifteen (27%) of the 56 hospitals were said to rely solely on GPs with limited surgical training for surgical services. At 45 (80%) of the 56 hospitals anesthesia services were provided by GPs, all of whom had limited additional training in anesthesia; 36 (64%) were said to rely solely on GPs for anesthesia services. Just over three quarters (76% [74/98]) of the administrators felt that their community''s surgical needs were well met. CONCLUSION: GPs with limited specialty training continue to play a role in providing surgical and anesthesia services in rural western Canada. This has implications for postgraduate training programs in Canada.  相似文献

Two empirical studies were performed to analyse cognitive processes in the reception of media stories on genetic engineering and their influence on attitudes to it. Three hundred and thirty-eight people each read three articles about genetic engineering and 51 people each watched three TV films. By means of the thought-listing technique, the thoughts occurring during reception were recorded and their content later analysed. Before and after presentation of the media stories, the recipients' attitudes to genetic engineering were measured. The articles and films evoked a broad spectrum of thoughts in the test subjects and included thoughts indicating an attitude critical of the media and sources. Evaluations were not primarily taken over from the content of the media but were generated by the subjects themselves - frequently in contrast to the media slant but in agreement with the test subjects' pre-attitudes. Depending on the reception, the same stories had a different influence on the attitudes of various people.  相似文献

We evaluated the prenatal care provided to 44 low-risk women by nurse-midwives (NMs) at a special clinic of a large obstetric referral hospital and a sample of 88 low-risk women attended by family physicians (FPs) in their offices. The women were matched on the basis of date of delivery, age, parity, number of previous miscarriages, gravidity, socioeconomic status and delivery after 32 weeks'' gestation. The Burlington Randomized Controlled Trial criteria, which reflect community standards of care, were updated and used to assess the information, which was provided on standard provincial prenatal care forms. Scoring was carried out blindly, and interrater reliability was high. A highly significant difference was found in the proportions of NM and FP charts that were rated adequate, superior or inadequate: 77% v. 24%, 7% v. 16% and 16% v. 60% respectively. The rate at which procedures were omitted (leading to an inadequate score) in the categories of initial assessment, monitoring and management also varied between the two patient groups. These findings, even when considered in terms of several biases that may have resulted in the high proportion of NM charts rated at least adequate, suggest that NMs provide prenatal care to low-risk women that is comparable, if not superior, to the care provided by FPs.  相似文献

The risk of manifestations of ischaemic heart disease (IHD) in fertile women is elevated during pregnancy and the post-partum period. With increasing maternal age and a higher prevalence of cardiac risk factors, the incidence of IHD during pregnancy is rising. However, information in the literature is scarce. We therefore performed a retrospective cohort study and systematically reviewed the overall (1975–2013) and contemporary (2005–2013) literature concerning IHD presenting during pregnancy or in the post-partum period. We report two cases of IHD with atypical presentation during pregnancy or post-partum. In our review, we describe 146 pregnancies, including 57 contemporary cases (2005–2013). Risk factors for IHD were present in 80 %. Of the cases of IHD, 71 % manifested in the third trimester or the post-partum period, and 95 % presented with chest pain. The main cause was coronary dissection (35 %), or thrombus/emboli (35 %) in the more contemporary group. Maternal mortality was 8 % (6 % in the contemporary group), and the main cardiac complication was ventricular tachycardia (n = 17). Premature delivery rate was 56 %, and caesarean section was performed in 57 %. Perinatal mortality was 4 %. In conclusion, IHD during pregnancy or in the post-partum period has high maternal mortality and morbidity rates. Also, premature delivery and perinatal mortality rates are high.
