Reporting Science and Conflicts of Interest in the Lay Press

BACKGROUND: Forthright reporting of financial ties and conflicts of interest of researchers is associated with public trust in and esteem for the scientific enterprise. METHODS/PRINCIPAL FINDINGS: We searched Lexis/Nexis Academic News for the top news stories in science published in 2004 and 2005. We conducted a content analysis of 1152 newspaper stories. Funders of the research were identified in 38% of stories, financial ties of the researchers were reported in 11% of stories, and 5% reported financial ties of sources quoted. Of 73 stories not reporting on financial ties, 27% had financial ties publicly disclosed in scholarly journals. CONCLUSIONS/SIGNIFICANCE: Because science journalists often did not report conflict of interest information, adherence to gold-standard recommendations for science journalism was low. Journalists work under many different constraints, but nonetheless news reports of scientific research were incomplete, potentially eroding public trust in science

Interactions with the pharmaceutical industry and the practice, knowledge and beliefs of medical oncologists and clinical haematologists: a systematic review

BACKGROUND: No previous review has assessed the extent and effect of industry interactions on medical oncologists and haematologists specifically. METHODS: A systematic review investigated interactions with the pharmaceutical industry and how these might affect the clinical practice, knowledge and beliefs of cancer physicians. MEDLINE, Embase, PsycINFO and Web of Science Core Collection databases were searched from inception to February 2021. RESULTS: Twenty-nine cross-sectional and two cohort studies met the inclusion criteria. These were classified into three categories of investigation: (1) extent of exposure to industry for cancer physicians as whole (n = 11); (2) financial ties among influential cancer physicians specifically (n = 11) and (3) associations between industry exposure and prescribing (n = 9). Cancer physicians frequently receive payments from or maintain financial ties with industry, at a prevalence of up to 63% in the United States (US) and 70.6% in Japan. Among influential clinicians, 86% of US and 78% of Japanese oncology guidelines authors receive payments. Payments were associated with either a neutral or negative influence on the quality of prescribing practice. Limited evidence suggests oncologists believe education by industry could lead to unconscious bias. CONCLUSIONS: There is substantial evidence of frequent relationships between cancer physicians and the pharmaceutical industry in a range of high-income countries. More research is needed on clinical implications for patients and better management of these relationships. REGISTRATION: PROSPERO identification number CRD42020143353

Public opinions about overdiagnosis:A national community survey

Despite evidence about the "modern epidemic" of overdiagnosis, and expanding disease definitions that medicalize more people, data are lacking on public views about these issues. Our objective was to measure public perceptions about overdiagnosis and views about financial ties of panels setting disease definitions.We conducted a 15 minute Computer Assisted Telephone Interview with a randomly selected community sample of 500 Australians in January 2014. We iteratively developed and piloted a questionnaire, with a convenience sample (n=20), then with participants recruited by a research company (n=20). Questions included whether respondents had been informed about overdiagnosis; opinions on informing people; and views about financial ties among panels writing disease definitions.Our sample was generally representative, but included a higher proportion of females and seniors, typical of similar surveys. American Association for Public Opinion Research response rate was 20% and cooperation rate was 44%. Only 10% (95% CI 8%-13%) of people reported ever being told about overdiagnosis by a doctor. 18% (95% CI 11%-28%) of men who reported having prostate cancer screening, and 10% (95% CI 6%-15%) of women who reported having mammography said they were told about overdiagnosis. 93% (95% CI 90%-95%) agreed along with screening benefits, people should be informed about overdiagnosis. On panels setting disease definitions, 78% (95% CI 74%-82%) felt ties to pharmaceutical companies inappropriate, and 91% (95% CI 82%-100%) believed panels should have a minority or no members with ties. Limitations included questionnaire novelty and complexity.A small minority of Australians surveyed, including those reporting being screened for prostate or breast cancer, reported being informed of overdiagnosis; most believed people should be informed; and a majority felt it inappropriate that doctors with ties to pharmaceutical companies write disease definitions. Results suggest strategies to better inform people about overdiagnosis, and review disease definition processes, have significant public sympathy

The Tobacco Industry’s Role in the 16 Cities Study of Secondhand Tobacco Smoke: Do the Data Support the Stated Conclusions?

BACKGROUND: Since 1996, the tobacco industry has used the 16 Cities Study conclusions that workplace secondhand tobacco smoke (SHS) exposures are lower than home exposures to argue that workplace and other smoking restrictions are unnecessary. OBJECTIVES: Our goal was to determine the origins and objectives of the 16 Cities Study through analysis of internal tobacco industry documents and regulatory agency and court records, and to evaluate the validity of the study’s conclusions. RESULTS: The tobacco industry’s purpose in conducting the 16 Cities Study was to develop data showing that workplace SHS exposures were negligible, using these data to stop smoking restrictions by the U.S. Occupational Safety and Health Administration. The extensive involvement of R.J. Reynolds Tobacco Company and the tobacco industry’s Center for Indoor Air Research in controlling the study was not fully disclosed. The study’s definition of “smoking workplace” included workplaces where smoking was restricted to designated areas or where no smoking was observed. This definition substantially reduced the study’s reported average SHS concentrations in “smoking workplaces” because SHS levels in unrestricted smoking workplaces are much greater than in workplaces with designated smoking areas or where no smoking occurred. Stratifying the data by home smoking status and comparing exposures by workplace smoking status, however, indicates that smoke-free workplaces would halve the total SHS exposure of those living with smokers and virtually eliminate SHS exposure for most others. CONCLUSIONS: Data in the 16 Cities Study reveal that smoke-free workplaces would dramatically reduce total SHS exposure, providing significant worker and public health benefits

Early remodeling of the neocortex upon episodic memory encoding

Understanding the mechanisms by which long-term memories are formed and stored in the brain represents a central aim of neuroscience. Prevailing theory suggests that long-term memory encoding involves early plasticity within hippocampal circuits, whereas reorganization of the neocortex is thought to occur weeks to months later to subserve remote memory storage. Here we report that long-term memory encoding can elicit early transcriptional, structural, and functional remodeling of the neocortex. Parallel studies using genome-wide RNA sequencing, ultrastructural imaging, and whole-cell recording in wild-type mice suggest that contextual fear conditioning initiates a transcriptional program in the medial prefrontal cortex (mPFC) that is accompanied by rapid expansion of the synaptic active zone and postsynaptic density, enhanced dendritic spine plasticity, and increased synaptic efficacy. To address the real-time contribution of the mPFC to long-term memory encoding, we performed temporally precise optogenetic inhibition of excitatory mPFC neurons during contextual fear conditioning. Using this approach, we found that real-time inhibition of the mPFC inhibited activation of the entorhinal–hippocampal circuit and impaired the formation of long-term associative memory. These findings suggest that encoding of long-term episodic memory is associated with early remodeling of neocortical circuits, identify the prefrontal cortex as a critical regulator of encoding-induced hippocampal activation and long-term memory formation, and have important implications for understanding memory processing in healthy and diseased brain states.Picower Institute for Learning and Memory (Innovation Fund)Massachusetts Institute of Technology.

Interactions between Australian cancer physicians and the pharmaceutical industry: a qualitative study

OBJECTIVES: To understand how and why Australian cancer physicians interact with the pharmaceutical industry. DESIGN: Qualitative study using semistructured interviews, performed by a medical oncologist. Thematic analysis using a combination of deductive and inductive codes. SETTING: Given the evidence on industry influences on clinical practice and the importance to the market of oncology drugs, we sought to better understand cancer physicians' experiences. Practising consultant medical oncologists and clinical haematologists from four Australian states were interviewed over Zoom. PARTICIPANTS: 16 cancer physicians were interviewed between November 2021 and March 2022, from 37 invited (response rate 43%). Most were medical oncologists (n=12 of 16, 75%) and male (n=9 of 16, 56%). OUTCOME MEASURES: The analysis of all interviews was based on grounded theory. Transcripts were coded and then codes formed into themes with supporting quotes. The themes were then placed into categories, used to describe the broad areas into which the themes could be grouped. RESULTS: Six themes were identified that fell within two broad categories: cancer physicians' views and experiences of interactions and management of these interactions. Views and experiences included: the transactional nature of relationships, risks of research dependence, ethical challenges and varied attitudes based on interaction type. Management themes included: lack of useful guidance and reduced interactions during the COVID-19 pandemic. These led to an overarching seventh theme, on the desire for a 'middle road'. Cancer physicians identified the transactional nature of industry relationships and felt uncomfortable with several types of interactions, including those with sales representatives. Most wanted less contact with industry, and the forced separation that occurred with the COVID-19 pandemic was generally welcome. CONCLUSIONS: Cancer physicians may have difficulty balancing the perceived need to interact with industry in modern cancer care while maintaining distance to minimise conflicts of interest. Further research is needed to assess management strategies in this area
