  • Brain imaging pinpoints mental illness biomarkers.

    Brain imaging pinpoints mental illness biomarkers.

    Newswise — Philadelphia, November 9, 2023  Research and treatment of psychiatric disorders are stymied by a lack of biomarkers – objective biological or physiological markers that can help diagnose, track, predict, and treat diseases. In a new study, researchers use a very large dataset to identify predictive brain imaging-based biomarkers of mental illness in adolescents. The work appears in Biological Psychiatry, published by Elsevier.

    Traditionally, psychiatric disorders such as depression have been diagnosed based on symptoms according to subjective assessments. The identification of biomarkers to aid in diagnosis and treatment selection would greatly advance treatments.

    In the current study, the investigators used brain imaging data from the Adolescent Brain Cognitive Development (ABCD) Study of nearly 12,000 children aged 9 to 10 at the beginning of the study. Modern neuroimaging techniques, including resting-state functional connectivity (rsFC) analysis, allow researchers to investigate the organization of brain circuits through their interaction with one another over time.

    Yihong Yang, PhD, senior author of the study, at the Neuroimaging Research Branch, National Institute on Drug Abuse, said, “Using a functional MRI dataset, we identified a brain connectivity variate that is positively correlated with cognitive functions and negatively correlated with psychopathological measures.”

    Cognition has long been studied in the context of mental disorders, and recent research has pointed to shared neurobiology between the two, as supported in this new study.

    This brain-based variate predicted how many psychiatric disorders were identified in participants at the time of the scan and over the following two years. It also predicted the transition of diagnosis across disorders over the two-year follow-up period.”

    Dr. Yang added, “These findings provide evidence for a transdiagnostic brain-based measure that underlies individual differences in developing psychiatric disorders in early adolescence.”

    John Krystal, MD, Editor of Biological Psychiatry, said of the work, “Mental illness in adolescence has emerged as a cardinal public health challenge in the post-COVID era. More than ever before, we would benefit from better ways to identify adolescents at risk. This study uses data from the landmark ABCD Study to illustrate how neuroimaging data could illuminate risk for mental illness across the spectrum of diagnoses.”

    Dr. Yang added, “Finding biomarkers of mental illnesses, rather than relying on symptoms, may provide a more precise means of diagnosis, and thereby aligning psychiatric diagnosis with other medical diagnoses.”

  • Uncovering insights into the early stages of schizophrenia.

    Uncovering insights into the early stages of schizophrenia.

    Newswise — Philadelphia, October 24, 2023 – Schizophrenia is a severe neuropsychiatric disease that remains poorly understood and treated. Schizophrenia onset is typically in adolescence or early adulthood, but its underlying causes are thought to involve neurodevelopmental abnormalities. Because human prenatal and postnatal brain tissue is exceedingly difficult to procure and therefore study, researchers have had limited opportunities to identify early disease mechanisms, especially during the critical prenatal period. Now, a pair of studies that appear in Biological Psychiatry, published by Elsevier, use new technology to study schizophrenia in models of early human brain development.

    The first study used a unique approach involving three-dimensional brain organoids, which are known to recapitulate fetal brain development. The researchers, led by first author Ibrahim A. Akkouh, PhD, and senior author Srdjan Djurovic, PhD, both at Oslo University Hospital, collected skin cells from 14 patients with schizophrenia and 14 healthy controls and generated induced pluripotent stem cells (iPSCs), which they then manipulated to develop into brain-like cortical spheroids.

    The organoids grown from patients and controls differed in their expression of thousands of genes – in line with the finding that the genetic influences on schizophrenia are many and very small. However, among the genes, those associated with neuronal axons stood out as a group.

    Dr. Akkouh explained, “We identified persistent axonal dysregulation as an early contribution to disease risk.”

    Importantly, the researchers assessed organoid maturation at several time points, which enabled them to establish the persistent nature of the disturbances throughout development.

    Dr. Akkouh added, “Our findings provide novel and hitherto inaccessible insights into the molecular basis of schizophrenia during early brain development.”

    In the second study, researchers led by Roy H. Perlis, PhD, at Harvard Medical School, focused on a particular genetic risk locus. The schizophrenia risk locus 15q11.2, a particular chromosomal region containing four genes, has a penetrance of over 10%, translating to a doubling of risk for schizophrenia among people carrying an unusual copy number of this genetic region. One gene in the locus, CYFIP1, has been associated with synaptic function in neurons and confers increased risk for neurodevelopmental disorders including schizophrenia and autism.

    CYFIP1 is highly expressed in microglia, the brain’s own immune cells, but its function there is unknown. Microglia are known to carry out synaptic pruning, in which they “eat” excess synaptic structures, a process critical to healthy brain development.

    Dr. Perlis and colleagues collected blood cells from healthy volunteers and isolated iPSCs, which they then manipulated to differentiate into microglia-like cells. The researchers then used CRISPR technology to remove functional CYFIP1 from the cells.

    Dr. Perlis said of the work, “Our findings suggest that changes in the behavior and function of microglia due to aberrant CYFIP1 function, such as through coding or copy number variants, could affect microglial processes such as synaptic pruning, homeostatic surveillance, and neuronal maintenance, which are critical for proper brain development and function. This could contribute to CYFIP1-related neurodevelopmental and psychiatric disorders resulting in part from microglia dysfunction. Among the specific disorders linked to variation in CYFIP1 are both autism and schizophrenia.”

    John Krystal, MD, Editor of Biological Psychiatry, commented, “The biology of schizophrenia is very complex and yet two themes represented by these two studies seem to be very important: the increased rate of elimination of glutamatergic synapses during development, and disturbances in the signaling properties of these glutamate synapses. These two disturbances could perturb circuit function in ways that are critical to development of symptoms and cognitive impairments associated with schizophrenia.”

    Dr. Perlis added, “More broadly, our findings highlight the importance of looking beyond neurons to understand risk genes. While finding risk loci may be the first step in understanding the role of genes in brain diseases, it’s only a first step; figuring out the relevant cell type, and what those genes are doing, is absolutely critical in moving from association to – we hope – actual treatments.”

  • Heat-Related Illnesses Surge Among US Veterans

    Heat-Related Illnesses Surge Among US Veterans

    Newswise — Philadelphia, August 22, 2023 – Researchers report a statistically significant and clinically important increase in heat related illnesses among patients at US Department of Veteran Affairs (VA) health facilities across the United States between 2002 and 2019. The study, which appears in The Journal of Climate Change and Healthpublished by Elsevier, documents far-reaching negative consequences of extreme-weather.

    Lead investigator Thomas F. Osborne, MD, VA Palo Alto Healthcare System and Stanford University School of Medicine, commented, “Our goal is to provide the best care for our patients, and understanding health risk is critical to our mission. Our team has incredible analytics staff, which, combined with expertise from partners at the CDC, has empowered us to uncover important insights. The data are a call to action as they expose a steady increase in the incidence of severe heat related illnesses in our US Veteran patient population. Although no one is immune from this danger, those who are traditionally the most vulnerable face the greatest risk of heat related illnesses.”

    Not surprisingly, the study found that specific groups of patients, such as those with existing health conditions and within specific ethnic groups, experienced higher rates of heat related illness.

    Co-investigator Zachary Veigulis, MS, US Department of Veterans Affairs, Palo Alto Healthcare System, and Department of Business Analytics, Tippie College of Business, University of Iowa, noted, “The extensive electronic health records from the VA, the US’s largest healthcare system, made it possible to understand the scope and scale of the growing danger and predict and identify individuals at greatest risk so we can target interventions.”

    While every state had residents that suffered heat related illnesses during the study period, the state-by-state numbers did not mirror geographic climate trends, possibly because the traditionally warmer states had already adopted policies, procedures, and practices to mitigate the health consequences of environmental heat. Another finding that suggested interventions reduce the growing health risk was the declining rate of heat related illness for homeless US Veterans in the second half of the study’s timeframe, a period after the launch and expansion of additional VA homeless health and wellness programs.

    Dr. Osborne added, “This assessment represents a critical first step in understanding the challenge, which is required to inform optimal care and prevention strategies. However, there is much more work to be done. While the physical impact of environmental heat is critically important, it is only one of many climate-related health dangers. Climate change-related health risks such as the unprecedented spread of infectious disease, wildfires, migration, infrastructure damage, as well as food and water insecurity are now central issues of our time. Urgent collaborative action is required to avoid additional suffering.”

  • Higher risk of Type 2 Diabetes for victims of partner violence and child abuse

    Higher risk of Type 2 Diabetes for victims of partner violence and child abuse

    Newswise — Ann Arbor, August 17, 2023 – According to the results of a new study in the American Journal of Preventive Medicine, published by Elsevier, exposure to interpersonal violence throughout childhood or adulthood increases an individual’s chance of developing adult-onset diabetes by more than 20%. Data showed the risk level is similar among adult males and females and lower income Black and White Americans.

    Lead investigator Maureen Sanderson, PhD, Department of Family and Community Medicine, Meharry Medical College, explained, “While previous research has linked exposure to interpersonal violence with a higher risk for developing type 2 diabetes, our study is the first to confirm a consistent association among different genders and races within a large, diverse population. Moreover, we were able to establish the temporal sequence for experiencing violence and the subsequent risk of developing diabetes over time.”

    Previous research has linked lifetime exposure to interpersonal violence or abuse to an increased risk of chronic psychosocial stress, anxiety, depression, and obesity. The investigators took a deeper look at the relationship between these factors, particularly obesity, and the risk of developing adult-onset diabetes using data from the Southern Community Cohort Study, a large study of an economically and ethnically diverse population in the southeastern US. More than 25,000 participants were contacted multiple times from 2002 to 2015, answering questions about partner violence (including adult psychological harm, physical violence, and threats), child abuse and neglect (physical, sexual, or emotional abuse), and current health (including diagnoses for adult-onset diabetes).

    Co-investigator Ann Coker, PhD, Department of Obstetrics and Gynecology, College of Medicine and Center for Research on Violence Against Women, University of Kentucky,  noted, “From this uniquely diverse cohort of over 25,000 participants, we saw that two commonly occurring forms of interpersonal violence, partner violence and child abuse (36% and 32%, respectively, in the study group), increased the risk of developing adult-onset diabetes by 20-35% when compared to individuals in this same cohort who had not experienced interpersonal violence. These forms of violence increase the risk of trauma-associated stress disorders, which can cause adult-onset diabetes.”

    Experiencing both child abuse and adult violence increased the risk of developing diabetes by 35% for both Black and White participants and males and females.

    Rates of interpersonal violence, psychosocial distress, and obesity all increased during the COVID-19 pandemic. Dr. Sanderson commented, “Our finding that lifetime interpersonal violence was associated with a significantly increased risk of developing diabetes across race and gender before the additional social stress of the COVID-19 pandemic strongly suggests the need for helping professionals across disciplines to implement effective violence prevention and intervention strategies to reduce the short- and long-term social and health consequences of partner violence and child abuse.”

    Dr. Coker added, “The good news is that effective intervention and prevention resources exist that can help patients and communities prevent or reduce partner violence and child abuse/neglect and have an impact on health outcomes including type 2 diabetes.”

    The US Centers for Disease Control and Prevention’s National Center for Injury Prevention and Control provides toolkits for clinicians’ and communities’ use to prevent violence. Key strategies include strengthening economic supports for families, promoting social norms to protect against adversity and violence, ensuring strong starts for children, teaching skills, connecting youth to caring adults, and intervening to lessen harm.

    In clinics, professionals can use safe, sensitive, trauma-informed approaches to ask patients about their current or lifetime experiences with child abuse or neglect and partner violence.

    Co-investigator L. Lauren Brown, PhD, Department of Psychiatry & Behavioral Sciences, Meharry Medical College, noted, “These violence prevention strategies can reduce and ultimately prevent the lifelong consequences of child abuse and partner violence — but only if we screen and engage people for care. Asking about past violence can begin to address the chronic stress response that leads to diabetes. Asking about current violence can interrupt the violence with skillful follow-up from clinical and community-based resources.”

  • Promising Noninvasive Test Holds Potential for Early Detection Breakthrough in Bladder Cancer

    Promising Noninvasive Test Holds Potential for Early Detection Breakthrough in Bladder Cancer

    Newswise — Philadelphia, August 14, 2023 – Bladder cancer has a five-year survival rate of over 80% when detected early, but this rate declines significantly as the disease progresses to advanced stages. In a novel study in The Journal of Molecular Diagnosticspublished by Elsevier, investigators report on a promising new diagnostic tool that may pave the way for an important breakthrough in early diagnosis of bladder cancer in patients with blood in their urine (hematuria), reducing the number of potentially unnecessary invasive cystoscopies and alleviating the economic burden of the disease.

    One of the most common symptoms of bladder cancer is hematuria, which accounts for up to 20% of all urological visits. Hematuria is seen in approximately 85% of bladder cancer patients. However, hematuria is prevalent among adults and may have other causes. From 5-20% of hematuria cases are diagnosed with bladder cancer.

    Lead investigators Sungwhan An, PhD, CEO and Scientific Director, Genomictree, Inc., Daejeon, South Korea, and Ju Hyun Shin, MD, Department of Urology, Chungnam National University College of Medicine, Daejeon, South Korea, explain, “Diagnosing bladder cancer at an early stage is critical and not only can increase patient survival rates but can also contribute to reducing healthcare costs. Current guidelines recommend cystoscopy and imaging examinations for almost all patients presenting with hematuria for initial diagnosis of bladder cancer, but it is invasive, inconvenient, economically burdensome for patients, and frequently fails to detect early-stage bladder cancer. There is therefore an urgent need for a sensitive and precise technique to diagnose early bladder cancer effectively among patients with hematuria.”

    Investigators studied a novel biomarker called aberrant PENK methylation (mePENK), which has shown a high clinical correlation with bladder cancer in previous studies. The first of two independent studies focused on developing a highly sensitive methylation test for mePENK using urine DNA and evaluating its effectiveness in diagnosing bladder cancer in patients within the hematuria population. The cutoff value for the mePENK test was initially determined in a case-control study involving 175 bladder cancer patients and 143 non-malignant hematuria patients. The test exhibited a sensitivity of 86.9% and a specificity of 91.6% in distinguishing bladder cancer from non-malignant hematuria cases.

    A subsequent independent prospective clinical performance study comprising 366 hematuria patients scheduled for cystoscopy compared the mePENK test results with the cystoscopy findings and histological analysis as the reference standards. The overall sensitivity of the test in detecting 38 cases of bladder cancer at all stages was 84.2%, while the specificity reached 95.7%. Notably, the test demonstrated a sensitivity of 92.3% in detecting high-grade and advanced-stage bladder cancer.

    Dr. Shin notes, “Although the FDA (USA) has approved several urine biomarker–based products, these methods have not been effectively utilized for early bladder cancer diagnosis. There are some in vitro molecular diagnostic techniques that measure genetic and epigenetic biomarkers for bladder cancer that are undergoing clinical trials, but they have yet to provide sufficient clinical evidence for the initial diagnosis of primary bladder cancer.

    Dr. An adds, “In this study, we used a test based on a single biomarker, mePENK, to detect primary bladder cancer in hematuria patients, and compared its clinical performance with tests that combine multiple biomarkers. Surprisingly, our findings revealed that the mePENK test was equal to or even superior to these multiple biomarker tests. Furthermore, the noninvasive nature of using a urine sample and the simplified test procedure offer advantages such as a shorter turnaround time for sample processing and efficient and accurate analysis of results.”

    Sungwhan An concludes, “The present study showcases a breakthrough in diagnosing bladder cancer through a simple and effective diagnostic test that eliminates the need for unnecessary cystoscopy procedures. The results demonstrate high sensitivity and accuracy in detecting bladder cancer. Using void urine as a sample offers significant advantages, ensuring easy accessibility to diagnostic opportunities for patients. The test has the potential to significantly reduce bladder cancer–related deaths and medical expenses. To implement the test in clinical practice larger-scale prospective clinical trials are needed, and we are actively pursuing that goal.”

    Bladder cancer is the sixth most common cancer in the world. Bladder cancer has a five-year survival rate of over 80% when detected early, but this rate significantly declines as it progresses to advanced stages, necessitating bladder removal and having a high risk of recurrence. As a result, bladder cancer ranks among the most expensive cancers to treat and manage.

  • Genes Define Eyebrow Look: Study

    Genes Define Eyebrow Look: Study

    Newswise — Philadelphia, June 5, 2023 – The first gene mapping study on eyebrow thickness in Europeans discovered three previously unreported genetic loci, as reported in a Letter to the Editor in the Journal of Investigative Dermatology, published by Elsevier. The study conducted by the International Visible Trait Genetics (VisiGen) Consortium demonstrates that eyebrow appearance has partly the same and partly different underlying genes in people from different parts of the world.

    The appearance of human eyebrows is not just a matter of grooming but is in the genes. Eyebrow thickness, as any other appearance trait, is highly heritable. Thus far, genetic knowledge on eyebrow thickness has been very limited and solely restricted to non-Europeans. This study is the first genome-wide association study (GWAS) on eyebrow thickness in Europeans. By identifying new genes and rediscovering some of the genes previously identified in non-Europeans, the study expands genetic knowledge on human eyebrow variation, which is of broad interest and has implications for dermatology and other fields.

    Previous studies were performed among Latin American and Chinese individuals, establishing four eyebrow thickness -associated genetic loci. Because no European eyebrow thickness GWAS had been reported, researchers did not know whether the genetic eyebrow thickness effects described in non-Europeans persist in Europeans, or whether there are European-specific genetic loci involved in eyebrow thickness, or both.

    Lead investigator Prof. Dr. Manfred Kayser, Department of Genetic Identification, Erasmus MC University Medical Center Rotterdam, and co-chair of the VisiGen Consortium responsible for this study, commented, “Despite the immense efforts in mapping genes underlying human complex traits, we still know much more about the genes that make us sick than about those behind our healthy looks. For the first time, we performed a gene mapping study on eyebrow thickness variation in Europeans. Previous genetic knowledge on eyebrow thickness was limited and solely restricted to non-Europeans. We discovered new genes involved in eyebrow variation in Europeans and rediscovered some of the genes previously identified in non-Europeans.”

    The study among 9,948 individuals from four groups of European ancestry not only discovered three previously unreported genetic loci associated with eyebrow thickness, but also rediscovered two of the four genetic loci previously found in non-Europeans. Two other genetic loci previously reported in non-Europeans had minimal effects in Europeans, due to very low allele frequencies in Europeans.

    Prof. Dr. Kayser concluded, “Our study significantly improves the genetic knowledge of human eyebrow appearance by increasing the number of known genes from four to seven and delivers new targets for future functional studies. By having demonstrated that eyebrow variation is determined by both shared and distinct genetic factors across continental populations, our findings underline the need for studying populations of different ancestries for unveiling the genetic basis of human traits, including, but not restricted to, physical appearance.”

  • ‘It Feels Like Things Are Breaking Open’: High Publishing Charges Spur Neuroscientists to Start Their Own Journal

    ‘It Feels Like Things Are Breaking Open’: High Publishing Charges Spur Neuroscientists to Start Their Own Journal

    The editors of a prominent neuroscience journal are sending a clear message to their publisher — and, they hope, to the broader academic-publishing community — by resigning en masse to begin a new journal in protest of what they say are “unethical and unsustainable” publishing fees.

    More than 40 handling editors, associate editors, senior editors, and editors in chief for NeuroImage and its companion journal NeuroImage: Reports, which are published by Elsevier, on Monday announced they were leaving their positions to assume similar roles at the newly formed Imaging Neuroscience, which will be published by the nonprofit MIT Press. They plan for the new journal to eclipse NeuroImage in standing, saying the fact that the entire editorial staff is making the shift will ensure the new journal’s quality.

    The high-profile move is the latest chapter in the long-unfolding battle over who pays and who benefits in the academic-publishing world. The departure from a well-regarded journal, and the plan to mount direct competition to it, also highlight the complex ecosystem that surrounds journals’ prestige and impact — and the interplay of a publisher’s reach and scale with the academic bona fides of the scholars who run a title.

    The NeuroImage saga began in June 2022, when editors formally asked Elsevier, the Dutch publishing company that has put out the journal since its inception in 1992, to lower the article-processing charge — the amount authors must pay to publish their work in NeuroImage — to under $2,000, the resigning editors wrote in their announcement. The current charge is $3,450, a price they say is prohibitive to many scholars, particularly those with funding restrictions or who work in countries with less well-resourced research institutions.

    In March, with no reduction having been offered, the NeuroImage team threw down a gauntlet: Lower the processing charge, or all of us will resign. That threat became reality this week, when the entire team — from handling editors to the editor in chief — officially left the journal. Elsevier representatives, they wrote, told them that the article-processing charge, or APC, wouldn’t be lowered “because they believe that market forces support the current APC.”

    In a statement, Elsevier said it was “disappointed” in the editorial board’s decision and that it had “engaged constructively” in recent years to turn the journal open access, making it free to read. The company has tapped interim editors and plans to establish a permanent team of both in-house and external editors to keep publishing.

    While the outgoing editors won’t handle any new submissions to NeuroImage, they plan to work until the end of 2023 on papers that have already been submitted to that journal. They hope to be ready to accept submissions to Imaging Neuroscience by mid-July. That’s when they plan to pick up right where they left off, said Shella D. Keilholz, a professor at Georgia Tech and Emory Universitywho was a senior editor of the journal. “I think that we can basically keep NeuroImage going, just with a different name,” Keilholz said. “The journal that Elsevier continues to run, they may call it NeuroImage, but it’s not going to be NeuroImage anymore.”

    High Costs

    The scholars’ exodus from NeuroImage shines a spotlight on the economics of academic publishing and the open-access movement. A key factor, if not the central one, is the article-processing charge, which publishing companies say is necessary for covering costs. As a one-time fee paid by a scholar or her institution prior to an article’s publication, a processing charge covers expenses incurred to copy edit, produce, and publish an article. The charges vary by discipline and publisher, but in many cases they have gradually risen over the years, as with NeuroImage. (The journal became fully open access in 2020, with an APC of $3,000; the price was hiked twice to reach its current rate of $3,450.)

    Elsevier said in a statement that its policy is to set its processing charge at a rate that is competitively below the market average, relative to a journal’s quality. “The fee that has been set for NeuroImage is below that of the nearest comparable journal in its field,” Elsevier’s statement read. That comparison was based on comparative journals’ field-weighted citation index, though an Elsevier spokesperson could not immediately identify NeuroImage‘s “nearest comparable journal.” The journal Nature Neuroscience, which is published by Springer Nature, charges $11,690; Human Brain Mapping, a Wiley publication, charges $3,850.

    We’re taking a risk because we’re disrupting this journal that we all love.

    But journal editors don’t earn much to do their work, and peer reviewers evaluate papers for free, which the NeuroImage editors said contributes to an unfairly large profit margin for publishing companies. Further complicating the matter is the role of public money, said Kristen M. Kennedy, an associate professor in the behavioral-sciences department at the University of Texas at Dallas and a former senior editor of NeuroImage. Citizens’ tax money supports the work of scientists through grants from agencies like the National Institutes of Health and the National Science Foundation. As scholars, “we’re having to pay to do the science, but then we’re having to pay a third party who didn’t have anything to do with the science to disseminate the information, and they’re for-profit,” Kennedy said. “The taxpayers who’ve paid for the grant money to exist, if they want to read the outcome of that science, they then have to pay again, because all of our publications are put behind a paywall behind these major publishing houses.”

    This was part of the rationale behind the Biden administration’s decision last summer to issue guidance that federally funded research should be made freely and immediately available to the public.

    A New Leading Journal?

    As the scholars behind the new journal get started, they have several advantages, beginning with prominence. NeuroImage, they say, has a longstanding reputation as the field’s leading journal, with both the highest impact factor and the most papers published each year in the discipline. If early online reception is any indication, they’ll have support for their departure: Many academics responded to the announcement by promising to send their work to Imaging Neuroscience, and more than 850 scholars have volunteered as peer reviewers for the new journal. Some have told the editors that they plan to retract their in-progress submissions at NeuroImage or will wait to submit their work until Imaging Neuroscience is ready to receive it. That, the editors said, includes early-career researchers who’ve promised to ask their principal investigators to submit work to the new journal.

    A lower article-processing charge is another possible advantage. The final price is yet to be announced, but the editors hope it will be less than half of the current price at NeuroImage, and they’ve said the processing charge will be waived entirely for scholars at institutions in low- and middle-income countries. Cindy Lustig, a professor of psychology at the University of Michigan at Ann Arbor and a former senior editor at NeuroImage, said that she and her colleagues frequently heard complaints about the journal’s high processing charge. That’s why, she said, they were both “obligated and empowered” to make the shift. “We were,” she said, “big enough and respected enough to do it right.” For a smaller or less well-known journal, an exodus from the publisher would be a more difficult — if not disastrous — endeavor.

    The cohesion among the now-former NeuroImage team was another plus. To marshal more than three-dozen scholars to an unanimous decision — for which Lustig credited the editor in chief, Stephen Smith of the University of Oxford — was unusual. At another journal, Kennedy imagined, “maybe their editor in chief might go to them and say, ‘Hey, we want to defect. Are you with me?’ And they might get some murmurs and a couple of yeses, who knows? But our journal is so well-honed, and we’ve just worked so well with each other for so long.”

    Even for a group of well-known and collegial scholars, starting a new journal can be a tricky proposition. While they’ve found an alternative publisher, they still need to land on a processing charge that’s both equitable and sustainable and set up shop under a new name, then hope that their peers in the field follow through on their promises to send their work to the new publication. “We’re taking a risk because we’re disrupting this journal that we all love, but it’s riskier to do nothing and to wait and watch these prices continue to go up,” Keilholz said.

    The founders of Imaging Neuroscience are keenly aware of the implications that their decision to leave NeuroImage could have for the discipline. For many early-career researchers, Lustig said, getting their first paper published in NeuroImage was a major career milestone, a sign that “‘OK, I can breathe now; I’m going to get a job,’” she said. As the shift plays out, it’s possible that NeuroImage‘s reputation will decline, while it could take several years for Imaging Neuroscience to accumulate the metrics that are traditionally considered hallmarks of success. (The Journal Citation Reports, for example, only measures impact factor after a journal has been indexed for two years.)

    We feel that the era of extreme levels of profit made by some publishers is coming to an end.

    Will the new journal succeed in its goal to “replace NeuroImage as our field’s leading journal,” as the editors wrote in their announcement? Lisa Janicke Hinchliffe, a professor at the library at the University of Illinois at Urbana-Champaign, said that depends on how the new journal is measured — and whether the editors’ aim is to topple their old journal. “I think they could very well build this into a top journal in the field,” she said. “Whether that will mean that Elsevier’s journal falls, that’s a different question.”

    A Difficult Journey

    While the scholars’ decision to leave Elsevier’s publication to start their own journal is unusual, it’s not unprecedented. According to one list, several-dozen journals have made “declarations of independence” in the last quarter-century. These predecessors’ experiences are instructive.

    Shortly after the Scholarly Publishing and Academic Resources Coalition, or Sparc, formed in 1998, it started an effort called Declaring Independence to encourage journals’ editorial boards to walk away from commercial publishers. While a dozen or so journals did so at the time, Sparc later tabled the effort. “What we saw was it’s really hard to make that scale into a widespread solution or strategy,” Heather Joseph, the executive director, said. “It’s very labor-intensive to do this on a one-off, journal-by-journal basis.”

    As open access has taken root, Joseph said, authors who find themselves saddled with high processing charges have begun asking more questions about the model. “It feels,” she said, “like things are breaking open.” The former NeuroImage editors nodded to the same sentiment in their announcement: “Although we appreciate that commercial publishers need to make some profit, we feel that the era of extreme levels of profit made by some publishers is coming to an end.”

    Johan Rooryck, the executive director of the open-access project Coalition S, said the journey the Imaging Neuroscience team is about to embark on is a difficult one. There’s no infrastructure to draw on in doing so, a gap he’s working to address. Rooryck wants to create a “one-stop shop” where scholars can find those resources “without having to worry about the money, about the guidelines, about the submission system.” He envisions a platform that would allow prospective editorial teams to “pluck off elements from the shelf to set up their own journal in a few days.”

    But in the absence of such a system, he doesn’t see a wave of editorial defections in the coming months. “I don’t expect it to happen to hundreds or thousands of journals overnight. It happens now, and then that garners a lot of attention, and then we wait for the next one,” he said.

    Hinchliffe agreed. Without a place for a journal to go — like MIT Press for Imaging Neuroscience — editors’ aspirations of breaking free from the corporate restraints of a major publisher aren’t realistic. Even outlets like MIT Press, which has a strong open-access track record, don’t have infinite resources to establish new journals. “That’s the capacity question. It’s not researcher interest in different models, it’s the availability of opportunity to work in those other models,” she said. “So how many journals can these alternative places take up? I don’t have an answer. I can only observe that they don’t do too many at a time.”

    MIT Press, for one, starts one or two new journals each year, said Nick Lindsay, its director of journals and open access. “We don’t have the capacity to be able to take on many, many new titles a year, so we have to be judicious about what we do.” But, Lindsay added, the press is looking forward to working with the Imaging Neuroscience team, which he called a “natural fit.” “They know very clearly what they want to do and what they want to accomplish, and given their experience, they know how to go about doing it,” he said.

    In their unanimous decision to move, and in their broad community support, the Imaging Neuroscience team has already cleared the biggest hurdle, Rooryck said. “If the entire community moves, then what you have is an empty vessel. That empty vessel then is filled by whatever is left, so to speak, by people who are desperate to publish in a journal with an impact factor.”

    He would know: Along with his role at Coalition S, Rooryck is the editor in chief of Glossa, a linguistics journal he helped launch in 2015 after he and the other editors at Lingua, an Elsevier publication, resigned. The Glossa transition — along with a similar move in 2019 that saw the team behind Elsevier’s Journal of Informetrics break away to form Quantitative Science Studies — has been held up as an example for Imaging Neuroscience to follow. (Glossa, though, does not charge an article-processing charge, while Imaging Neuroscience will.) “It’s basically like a family buying a new car,” Rooryck said. “You ditch the old car; you buy a new car. What’s important? It’s the family that moves in that car. You’re not looking at any way at the vehicle.”

    The family in Rooryck’s metaphorical car — the editors at Imaging Neuroscience — are betting on the strength of that comparison. They’re hoping the reputation they’ve built as a collective will travel with them; that reputation, Kennedy said, is the reason behind NeuroImage‘s success. “That’s how the journal gets to the top of the ranks. It has very good scientists who submit papers to it, and it has a very, very good editorial board that selects from those the best, most sound, most impactful papers to publish,” she said. “That’s all us.”

  • How to achieve a functional cure for chronic hepatitis B

    How to achieve a functional cure for chronic hepatitis B

    Newswise — Geneva, March 30, 2023 – More than half of patients who suffer from chronic hepatitis B have the e antigen (HBeAg)-negative form of the disease. Even after many years of antiviral treatment with nucleos(t)ide analogues (NUC), lasting immune control is almost never seen. According to the current state of knowledge, those affected therefore require lifelong therapy. In the world’s first randomized controlled multicenter study – led by Leipzig University’s Faculty of Medicine and in partnership with the Centre for Clinical Studies (ZKS) – researchers have shown that many HBeAg-negative patients can achieve permanent immune control of hepatitis B if they discontinue antiviral therapy after a certain period of time. Their findings are published in the high-impact journal, the Journal of Hepatology.

    Hepatitis B is an inflammation of the liver caused by the hepatitis B virus that can lead to serious problems such as liver cirrhosis or liver cancer and is easily transmitted through body fluids. An estimated 350 million are chronically infected, making chronic hepatitis B one of the most common viral infections worldwide. People with chronic hepatitis B usually have to take antiviral medication for their entire life in order to reduce the viral load and normalize inflammation levels in the liver. Antiviral therapy consists of the administration of nucleoside or nucleotide analogues, which in patients with the HBeAg-negative form almost never leads to the permanent immune control that would allow the termination of treatment. The antiviral therapy is associated with high costs for the healthcare system and can cause serious side effects.

    Results currently published in the Journal of Hepatology show in a study of 166 HBeAg-negative patients from 20 clinics across Germany that after 96 weeks of observation many patients who discontinued an effective antiviral treatment that they had taken for at least four years achieved immune control of the disease. In 10% of the patients, immune control was demonstrated through loss of previously detectable hepatitis B surface antigen (HBsAg) in the blood, an event which is considered a functional cure of hepatitis B.

    By the end of the study, in about 41% of patients, hepatitis B virus levels in the blood were reduced to below the level of 2,000 units per millilitre, which according to international treatment guidelines means that there is no longer an indication for renewed antiviral therapy. Additionally, 77% of patients no longer had elevated liver inflammation levels. In contrast, no patient who continued antiviral treatment showed HBsAg loss.

    Study leader Professor Florian van Bömmel, senior physician in the Department of Hepatology at Leipzig University Hospital said, “We were able to show that in some patients discontinuing long-term therapy with nucleoside or nucleotide analogues after at least four years is more effective than continuing it, and that many patients no longer require antiviral therapy at all after discontinuation. In particular, patients who show low HBsAg levels when they discontinue treatment have a high chance of functional cure.”

    After discontinuation of treatment, all of the patients initially experienced a resurgence of hepatitis B virus replication and many also experienced transient renewed liver inflammation. Some patients with severe liver inflammation were then restarted on antiviral therapy to prevent liver damage. Patients with liver cirrhosis were not included in the study for safety reasons. No serious adverse events related to discontinuation of therapy occurred during the study. “However, in other studies, severe cases of hepatic inflammation were observed in a few cases after antiviral therapy was discontinued. Stopping NUC treatment should therefore only be carried out under the supervision of an experienced physician,” said the study leader.

    Professor van Bömmel and Professor Thomas Berg, head of the Department of Hepatology at Leipzig University Hospital, are confident that the results of the STOP-NUC trial will have a major impact on the overall development of hepatitis B therapy: “We expect that in the future international guidelines for the treatment of hepatitis B will refer to this study. By the middle of this year, results from the extension of the study will be evaluated and will show whether the number of patients with immune control continues to increase in the long term after discontinuation of antiviral treatment.”

  • Human contact makes for happier and healthier dairy calves

    Human contact makes for happier and healthier dairy calves

    Newswise — Philadelphia, February 20, 2023 – Calves’ well-being, including their physical and emotional health, is always top of mind for those in the dairy industry, particularly during the weaning stage. In a recent study appearing in JDS Communications®, published by Elsevier, researchers from the University of Florida demonstrated that socialization with other calves and humans—even for as little as five minutes—can improve overall calf well-being.

    Lead investigator Emily K. Miller-Cushon, PhD, of the University of Florida Department of Animal Sciences, Gainesville, FL, USA, explained that assessing how a calf is feeling is usually done by observing behaviors, especially abnormal behaviors which can include “sucking or chewing on their housing pens or bedding, on their pen-mates or human handlers—all of which are common in the period after calves are fed.” These kinds of behaviors are generally considered signs of frustration and can affect calves’ health.

    “Calves are active and seek stimulation following milk-feeding, so providing more things to do, like brushing, may calm calves, reducing sucking behaviors after feeding and increasing rest,” said Miller-Cushon.

    Because studies have already shown that calves seek out human contact, the researchers set out to understand how the human-animal relationship might impact these sucking behaviors. To find an answer, the team randomly assigned 28 Holstein heifer calves to either individual or paired housing from birth to seven weeks old and standardized their contact with humans over this period to include feeding and health exams. The calves began weaning at six weeks old; over a four-day study period during weaning, the researchers introduced additional human contact and continuously video-recorded its effects on behavior. During this window, each calf received two days of their normal amount of human contact and two experimental days, in which they received an extra five minutes of neck scratches with their familiar human handlers. 

    Why neck scratches? “We know from previous research that calves seem to enjoy tactile contact including brushing from humans. This kind of contact can reduce their heart rates, and calves lean into the scratches and stretch out their necks for more,” explained Miller-Cushon. “We also see that calves suck on the pen less when they have a stationary brush that they can rub against.”

    After analyzing the video recordings, the study team concluded that human contact does impact calf behavior and helps to promote calm and well-being. Those five minutes spent with humans reduced the duration of calves’ sucking behaviors and increased their amount of rest after meals. This decrease in sucking behavior was especially pronounced in the calves housed alone compared with those that had a pen-mate—indicating the importance of socialization not just with humans but also with other calves.

    Miller-Cushon was careful to note that the human contact in the study did not eliminate sucking behaviors entirely, however: “Our findings showed benefits of human contact, but the results also suggest that our work is not done in finding the most beneficial and natural methods of feeding and housing our dairy calves.”

  • Cautionary tale or happy ending? Factors that make a difference in difficult mountain rescue efforts

    Cautionary tale or happy ending? Factors that make a difference in difficult mountain rescue efforts

    Newswise — Philadelphia, January 17, 2023 – A trapped mountaineer survived after enduring 16 frigid hours wedged in a crevasse on Denali (Mount McKinley) in Alaska. His long and difficult rescue in frigid conditions and care in the critical aftermath are examined in the current issue of the Wilderness Medical Society’s official journal, Wilderness & Environmental Medicine, published by Elsevier. This compelling case study highlights the distinguishing factors that led to the successful outcome.

    The mountaineer was wedged about 20 meters deep in the crevasse, waiting 4.5 hours for a rescue team to arrive, followed by an 11.5-hour extrication process. His condition deteriorated and he eventually lost consciousness. Even though the rescue team collectively felt there was little or no chance of survival, they continued rescue efforts until the victim was extricated from the crevasse. He was almost immediately placed in a hypothermia wrap with active warming, loaded onto a rescue helicopter, and transported to a hospital in Fairbanks, Alaska. He was released after 14 days and made a full recovery.

    “This case documents the heroic, persistent and expert rescue efforts of a group of people dedicated to saving lives. After conferring with the chief rescuer and chief of medical personnel, we pulled together our collective insights about the challenges of extracting climbers from extremely confined spaces and providing medical care to those who have had extended cold exposure,” explained lead investigator Gordon G. Giesbrecht, PhD, Laboratory for Exercise and Environmental Medicine, Faculty of Kinesiology and Recreation Management, Departments of Emergency Medicine and Anesthesia, University of Manitoba, Winnipeg, MB, Canada.

    Their recommendations build on lessons learned from a previously published case study of a helicopter pilot who died after being trapped in an icy crevasse for only four hours. In that paper, Dr. Giesbrecht identified the need to develop processes for search and rescue personnel to prevent circum-rescue collapse, which is a complex physiological response to extreme cold that is worsened by improper handling of the patient. He cautioned that rescuers should be trained with the principle that the colder the victim is, the more care is required to perform horizontal extrication as gently as possible. Adding a few minutes for gentle handling and to reposition will not significantly increase cold exposure, but will greatly minimize the chance of rescue collapse.

    “Responders should be aware of the causes, symptoms, and prevention of rescue collapse. Training should include techniques for transitioning a victim gently from vertical to a horizontal supine or, for narrower passages, to a lateral decubitus position. Even if a victim has to be hauled up in a vertical position, a simple technique using a sling or rope under the knees allows a simple, gentle and horizontal extrication from the crevasse to the surface,” noted Dr. Giesbrecht.

    This case emphasized the need to continue extrication and treatment efforts for a cold patient even when survival with hypothermia seems impossible. It also underscored the need for rescue teams to pre-plan equipment and procedures specific to crevasse rescue of potentially cold patients.

    This case highlights an important mix of preventive and resuscitative lessons and recommendations regarding crevasse rescue in an isolated location:

    • Urging climbers to rope up for glacier travel in areas with known and possible crevasses.
    • Making sure that any rescuers who descend into crevasses are continuously observed by someone who remains on the surface and has radio contact to call for immediate assistance.
    • Recognizing that respirations are often more easily detected than pulses.
    • Trying unorthodox extrication methods when necessary.
    • Rescue teams deployed for crevasse rescues should carry kits with a pneumatic hammer-chisel (important for extrication), a tripod and winch, a hypothermia wrap made of a sleeping bag and chemical heating blankets, onboard oxygen supply with an adapter that connects to nasal prongs or a patient’s mask, a mechanical chest compression device, an automated external defibrillator, and IV saline with a fluid warmer. The Denali National Park and Preserve mountaineering rangers now include such kits in their rescue aircraft.

    The investigators plan to submit a standardized rescue process based on these recommendations for publication after completing field testing in the summer of 2023.

    When asked about what he considered the most crucial factor for survival, Dr. Giesbrecht stressed that rescuers should never give up even when the patient’s survival with hypothermia seems impossible.

  • Whole-grain food consumption impacted by consumer skepticism and lack of labeling standard

    Whole-grain food consumption impacted by consumer skepticism and lack of labeling standard

    Newswise — Philadelphia, December 5, 2022 – Despite numerous health benefits and recommendations from dietary guidelines, whole-grain food intake remains low globally. A research article featured in the Journal of Nutrition Education and Behavior, published by Elsevier, studies consumer understanding of whole-grain food definitions and industry labeling practices.

    “Without clear regulation and labeling standards, the benefits of educating consumers on how to increase whole-grain intake may be lost,” says lead author Katrina R. Kissock, PhD, APD, School of Medical, Indigenous and Health Sciences, University of Wollongong, Wollongong, NSW, Australia. “This study supports the need for a global whole-grain labeling system based on standardized definitions to help consumers make informed food purchases.”

    This study recruited consumers with flyers in community locations as well as through social media. The resulting ten focus groups were asked open-ended questions on four topics: grain food choices and whole-grain consumption; identification of whole-grain foods; perception of labeling; and opinions on hypothetical package labels. In addition, 17 food industry representatives, including dietitians, food scientists, marketers, and regulatory personnel, were recruited by direct email to examine awareness and understanding of whole-grain food definitions and regulations; hypothetical adoption of whole-grain food definitions by the food industry; and how definition adoption might impact consumers.

    During focus group discussions, skepticism significantly impacted consumer understanding and consequently grain choices. The consumer focus groups expressed skepticism of grain food labeling, whole-grain content claims, symbols such as the Health Star Rating and marketing of products as healthy. Consumer comments included, “I don’t know how much whole grain a product has to have to get a label. Does it mean 5% or 3%?” and “I don’t have any idea what 16 grams of whole grain per serving means.”

    When looking at hypothetical labels, consumers had a strong preference towards use of whole grain within the name of the product as opposed to a separate and generic whole-grain content claim not in the name of the product, e.g., ”contains whole grain.” Industry representatives generally did not think consumers noticed that level of nuance in front of package labeling. A simple statement of the percentage of whole grain in a product was considered clear and easy to understand by consumers, and industry representatives agreed that the current percentages used by the Whole Grain Initiative definition were appropriate. Both consumers and food industry representatives identified problems with current labeling of whole-grain foods and highlighted the need for clear, consistent labeling.

    “It was evident that limited consumer understanding and confusion related to whole-grain foods contributed to skepticism, perceptions of healthfulness, and buying decisions,” concludes Dr. Kissock. “Definitions, regulations and consumer education are strategies that could improve consumption of whole-grain foods.”
