COVID-19 and 'immune boosting' on the internet: a content analysis of Google search results.

OBJECTIVE: The spread of misinformation has accompanied the coronavirus pandemic, including topics such as immune boosting to prevent COVID-19. This study explores how immune boosting is portrayed on the internet during the COVID-19 pandemic. DESIGN: Content analysis. METHODS: We compiled a dataset of 227 webpages from Google searches in Canada and the USA using the phrase 'boost immunity' AND 'coronavirus' on 1 April 2020. We coded webpages for typology and portrayal of immune boosting and supplements. We recorded mentions of microbiome, whether the webpage was selling or advertising an immune boosting product or service, and suggested strategies for boosting immunity. RESULTS: No significant differences were found between webpages that appeared in the searches in Canada and the USA. The most common types of webpages were from news (40.5%) and commercial (24.7%) websites. The concept of immune boosting was portrayed as beneficial for avoiding COVID-19 in 85.5% of webpages and supplements were portrayed as beneficial in 40% of the webpages, but commercial sites were more likely to have these portrayals. The top immune boosting strategies were vitamin C (34.8%), diet (34.4%), sleep (34.4%), exercise (30.8%) and zinc (26.9%). Less than 10% of the webpages provide any critique of the concept of immune boosting. CONCLUSIONS: Pairing evidence-based advice for maintaining one's health (eg, healthy diet, exercise, sleep) with the phrase immune boosting and strategies lacking in evidence may inadvertently help to legitimise the concept, making it a powerful marketing tool. Results demonstrate how the spread of misinformation is complex and often more subtle than blatant fraudulent claims.

Access and Management: Indigenous Perspectives on Genomic Data Sharing.

As genomic researchers are encouraged to engage in broad genomic data sharing, American Indian/Alaska Native/Native Hawaiian (AI/AN/NH) leaders have raised questions about ownership of data and biospecimens and concerns over emerging challenges and potential threats to tribal sovereignty. Using a community-engaged research approach, we conducted 42 semi-structured interviews with tribal leaders, clinicians, researchers, policy makers, and tribal research review board members about their perspectives on ethical issues related to genetics in AI/AN/NH communities. We report findings related to perspectives on genetic research, data sharing, and envisioning stronger oversight and management of data. In particular, participants voiced concerns about different models of data sharing, infrastructure and logistics for housing data, and who should have authority to grant access to data. The results will ultimately guide policy-making and the creation of guidelines and new strategies for tribes to drive the research agenda and promote ethically and culturally appropriate research.

Press releases issued by supplements industry organisations and non-industry organisations in response to publication of clinical research findings: a case-control study.

BACKGROUND: Dietary supplement use is increasing despite lack of evidence of benefits, or evidence of harm. Press releases issued by the supplements industry might contribute to this situation by using 'spin' (strategies to hype or denigrate findings) to distort the results of clinical studies. We assessed press releases issued in response to publication of clinical studies on dietary supplements. METHODS AND FINDINGS: We analyzed 47 supplements industry press releases and 91 non-industry press releases and news stories, generated in response to 46 clinical studies of dietary supplements published between 1/1/2005 and 5/31/2013. The primary outcome was 'spin' content and direction. We also assessed disposition towards use of dietary supplements, reporting of study information, and dissemination of industry press releases. More supplements industry press releases (100%) contained 'spin' than non-industry media documents (55%, P<0.001). Hyping 'spin' scores were higher in industry than non-industry media documents for studies reporting benefit of supplements (median 'spin' score 3.3, 95% CI 1.0-5.5 vs 0.5, 0-1.0; P<0.001). Denigratory 'spin' scores were higher in industry than non-industry media documents for studies reporting no effect (6.0, 5.0-7.0 vs 0, 0-0; P<0.001) or harm (6.0, 5.5-7.5 vs 0, 0-0.5; P<0.001) from a supplement. Industry press releases advocated supplement use in response to >90% of studies that reported no benefit, or harm, of the supplement. Industry press releases less frequently reported study outcomes, sample size, and estimates of effect size than non-industry media documents (all P<0.001), particularly for studies that reported no benefit of supplements. Industry press releases were referenced by 148 news stories on the websites of 6 organizations that inform manufacturers, retailers and consumers of supplements. CONCLUSIONS: Dietary supplements industry press releases issued in response to clinical research findings are characterized by 'spin' that hypes results that are favourable to supplement use and denigrates results that are not.

Goal: To analyze the changes produced by therapeutic massage on systemic autonomic activity by analyzing the modification of cardiac autonomic activity. Material and methods: A comparative study was performed on 15 women on the variability of heart rate variability (HRV) (RR interval) obtained by photoplethysmography for 2 20-minute sessions: control and massage. HRV was measured at 4 different times for periods of 5 minutes each. The massage session consisted of effleurage massage and wide-ranging sliding pressure. In addition, the participants had to fill out the well-being visual analogue scale (Well Being VAS) questionnaire immediately after the control and massage session. Results: The paired Student’s t-test was used to compare the results obtained. Pearson correlation coefficient was used to quantify the relationship existing between the different times in each one of the parameters. A statistically significant increase was observed in HRV (total power) as well as an increase in parasympathetic activity in the massage session during the last 5 minutes (relative to baseline) compared to control session. However, this response tends to decrease 5 minutes after its interruption/timeout. Finally, the Well Being VAS score shows a significant increase after the massage. However, its gain is not correlated to the changes in the physiological variables. Conclusions: The massage applied on healthy subjects affects the autonomic nervous system (AU)

Este artículo repasa una visión extranjera de la cultura española en un momento histórico crucial (AU)

This article aims to analyze a European view of the 17th century Spanish culture. Naude’s Advispour dresser une bibliothèque (1627) —translated twice into English: Instructions concerning erecting of a library (1661) and Advice on establishing a library (1950)— represents a wide set of bibliographic recommendations that constitute, among many other things, an excellent observatory of the Spanish culture in such a delicate time (AU)

Does a doctor have a duty to provide information and advice about complementary and alternative medicine?

It is argued that a doctor has a duty to provide information about reasonably available complementary and alternative medicine treatments where that information would be material to the particular patient or the hypothetical prudent patient. Given the vast array of such treatments available, doctors will want to rely on evidence-based medicine problem-solving skills to ascertain those treatments that are safe and efficacious. While the risk of litigation for failure to provide such information is probably low at this time, given the high rate of patient self-prescribing, it is necessary for a doctor to open a dialogue with a patient about complementary and alternative medicine to address safety concerns. In addition, it is important to facilitate access to the best of conventional and complementary treatments to ensure better health outcomes for the patient.

Obligation to advise of options for treatment--medical doctors and complementary and alternative medicine practitioners.

An important aspect of health professional's duty of care is to advise patients of the available options of treatment so that the patient can choose the form of treatment that suits her or his requirements. As CAM becomes more evidence-based and accepted, medical doctors need to consider the extent to which they should provide patients with information about those types of treatments. If a CAM treatment option is evidence-based, there is a strong argument that medical doctors should advise of this option for treatment to satisfy their duty. CAM practitioners should also provide details of options for treatment within their own modality but are not obliged to advise of medical options.

Ethical decision-making in prenatal diagnosis and termination of pregnancy: a qualitative survey among physicians and midwives.

OBJECTIVES: This study was aimed at exploring the conflicts and ethical problems experienced by professionals involved in prenatal diagnosis and termination of pregnancy (TOP) in order to improve the understanding of decision-making processes and medical practices in the field of prenatal diagnosis. METHODS: Qualitative study with in-depth tape-recorded interviews conducted in three tertiary care maternity units in France, between May 1999 and March 2000. All full-time obstetricians and half of the full-time midwives were contacted. Seventeen obstetricians and 30 midwives participated (three refusals, five missing). Interviews were transcribed and analysed successively by two different researchers. RESULTS: All respondents stated that prenatal diagnosis and TOP raised important ethical dilemmas, the most frequent being request for abortion in case of minor anomalies. They pointed out the inability of our society to appropriately care for disabled children and the risk of eugenic pressures. The decisions and practices in prenatal diagnosis should be debated throughout society. All respondents reported that their unit did not have protocols for deciding when a TOP was justifiable. The transmission of information to the women appeared to be a problematic area. Moral conflicts and emotional distress were frequently expressed, especially by midwives who mentioned the need for more discussions and support groups in their department. CONCLUSION: Health professionals involved in prenatal diagnosis face complex ethical dilemmas which raise important personal conflicts. A need for more resources for counselling women and for open debate about the consequences of the current practices clearly emerged.
