Impact of the coronavirus disease 2019 pandemic on the progression, prevalence, and incidence of myopia: A systematic review.

We systematically reviewed the literature on the effects of the coronavirus disease 2019 (COVID-19) pandemic on the progression, prevalence, and incidence of myopia. A comprehensive literature search was performed on PubMed, Cochrane Central Register of Controlled Trials, and Scopus databases. Studies included in the review assessed myopia progression, prevalence, and/or incidence as the primary outcome. Of 523 articles yielded in the initial search, 23 studies (6 cross-sectional and 17 cohort) were eligible for inclusion. Sixteen of these were conducted in China and one each in Hong Kong, Turkey, Spain, Israel, India, Korea, and Tibet. Quality appraisals were conducted with the Joanna Briggs Institute Critical Appraisal Checklists. Of the included studies, a large majority reported a greater myopic shift and increase in myopia prevalence during the COVID-19 pandemic compared to the pre-COVID-19 years. All three studies on myopia incidence showed increased incidence during the COVID-19 pandemic. Myopia progression accelerated during the COVID-19 pandemic, even in individuals using low-concentration atropine eye drops in two studies but not in those using orthokeratology treatment in one study. Overall, the studies found that the COVID-19 pandemic and its associated home confinement measures generally increased myopia progression, prevalence, and incidence, even in individuals using low-concentration atropine eye drops.

Dynamic radiologic changes in repeated barotraumatic frontal sinusitis: A CARE case report.

INTRODUCTION: Flight staff are at particular risk of iterative sinus barotrauma. We here report a case of barotraumatic atelectasic frontal sinusitis with dynamic radiologic change in frontal sinus volume. CASE REPORT: A 46-year-old air pilot was referred for right frontal pain occurring at each landing. Two sinus CT scans were taken: one after a period of intense flying and the other after a month without flying. In the right frontal sinus, a type-3 Kuhn cell changed in volume from 6×11×12mm to 13×18×19mm. The alteration involved a modification in the medial wall, which was demineralized and changed position within the frontal sinus. Removal during endoscopic frontal sinusotomy allowed complete resolution of pain. DISCUSSION: This article reports radiologic change in a frontal sinus wall in a setting of repeated barotraumatic frontal sinusitis with a dynamic atelectasic component. In iterative barotrauma, we advocate imaging at different time points. When the ostial obstruction is identified, functional aeration surgery can be applied.

The ethical challenges of diversifying genomic data: A qualitative evidence synthesis.

This article aims to explore the ethical issues arising from attempts to diversify genomic data and include individuals from underserved groups in studies exploring the relationship between genomics and health. We employed a qualitative synthesis design, combining data from three sources: 1) a rapid review of empirical articles published between 2000 and 2022 with a primary or secondary focus on diversifying genomic data, or the inclusion of underserved groups and ethical issues arising from this, 2) an expert workshop and 3) a narrative review. Using these three sources we found that ethical issues are interconnected across structural factors and research practices. Structural issues include failing to engage with the politics of knowledge production, existing inequities, and their effects on how harms and benefits of genomics are distributed. Issues related to research practices include a lack of reflexivity, exploitative dynamics and the failure to prioritise meaningful co-production. Ethical issues arise from both the structure and the practice of research, which can inhibit researcher and participant opportunities to diversify data in an ethical way. Diverse data are not ethical in and of themselves, and without being attentive to the social, historical and political contexts that shape the lives of potential participants, endeavours to diversify genomic data run the risk of worsening existing inequities. Efforts to construct more representative genomic datasets need to develop ethical approaches that are situated within wider attempts to make the enterprise of genomics more equitable.

Community partnerships are fundamental to ethical ancient DNA research.

The ethics of the scientific study of Ancestors has long been debated by archaeologists, bioanthropologists, and, more recently, ancient DNA (aDNA) researchers. This article responds to the article "Ethics of DNA research on human remains: five globally applicable guidelines" published in 2021 in Nature by a large group of aDNA researchers and collaborators. We argue that these guidelines do not sufficiently consider the interests of community stakeholders, including descendant communities and communities with potential, but yet unestablished, ties to Ancestors. We focus on three main areas of concern with the guidelines. First is the false separation of "scientific" and "community" concerns and the consistent privileging of researcher perspectives over those of community members. Second, the commitment of the guidelines' authors to open data ignores the principles and practice of Indigenous Data Sovereignty. Further, the authors argue that involving community members in decisions about publication and data sharing is unethical. We argue that excluding community perspectives on "ethical" grounds is convenient for researchers, but it is not, in fact, ethical. Third, we stress the risks of not consulting communities that have established or potential ties to Ancestors, using two recent examples from the literature. Ancient DNA researchers cannot focus on the lowest common denominator of research practice, the bare minimum that is legally necessary. Instead, they should be leading multidisciplinary efforts to create processes to ensure communities from all regions of the globe are identified and engaged in research that affects them. This will often present challenges, but we see these challenges as part of the research, rather than a distraction from the scientific endeavor. If a research team does not have the capacity to meaningfully engage communities, questions must be asked about the value and benefit of their research.

Persistent hypersomnia following repetitive mild experimental traumatic brain injury: Roles of chronic stress and sex differences.

Traumatic brain injury (TBI) is often more complicated than a single head injury. An extreme example of this point may be military service members who experience a spectrum of exposures over a prolonged period under stressful conditions. Understanding the effects of complex exposures can inform evaluation and care to prevent persistent symptoms. We designed a longitudinal series of non-invasive procedures in adult mice to evaluate the effects of prolonged mild stress and head injury exposures. We assessed anxiety, depression, and sleep-wake dysfunction as symptoms that impact long-term outcomes after mild TBI. Unpredictable chronic mild stress (UCMS) was generated from a varied sequence of environmental stressors distributed within each of 21 days. Subsequently, mice received a mild blast combined with closed-head mild TBI on 5 days at 24-h intervals. In males and females, UCMS induced anxiety without depressive behavior. A major finding was reproducible sleep-wake dysfunction through 6- to 12-month time points in male mice that received UCMS with repetitive blast plus TBI events, or surprisingly after just UCMS alone. Specifically, male mice exhibited hypersomnia with increased sleep during the active/dark phase and fragmentation of longer wake bouts. Sleep-wake dysfunction was not found with TBI events alone, and hypersomnia was not found in females under any conditions. These results identify prolonged stress and sex differences as important considerations for sleep-wake dysfunction. Furthermore, this reproducible hypersomnia with impaired wakefulness is similar to the excessive daytime sleepiness reported in patients, including patients with TBI, which warrants further clinical screening, care, and treatment development.

Risk Factors for Reinfection with SARS-CoV-2 Omicron Variant among Previously Infected Frontline Workers.

In a cohort of essential workers in the United States previously infected with SARS-CoV-2, risk factors for reinfection included being unvaccinated, infrequent mask use, time since first infection, and being non-Hispanic Black. Protecting workers from reinfection requires a multipronged approach including up-to-date vaccination, mask use as recommended, and reduction in underlying health disparities.

Values and Practices to Strengthen Genetic Research Partnerships with Indigenous Communities.

Genetic datasets lack diversity and include very few data from Indigenous populations. Research models based on equitable partnership have the potential to increase Indigenous participation and have led to successful collaborations. We report here on a meeting of participants in four Indigenous community-university partnerships pursuing research on precision medicine. The goal of the meeting was to define values and practices that strengthen opportunities for genetic research. The group accorded the highest priority to developing trusting relationships, ensuring respect for Indigenous community authority, and pursuing research that has the potential to lead to community benefit. Supporting priorities included incorporation of Indigenous expertise in research planning, transparent communication, and development of community capacity, including capacity to participate in formulating research questions, informing research methodology, and leading research projects. Participants also noted the importance of attention to social determinants of health so that genetic contributors to health are evaluated in the appropriate context.

Federated learning and Indigenous genomic data sovereignty.

Indigenous peoples are under-represented in genomic datasets, which can lead to limited accuracy and utility of machine learning models in precision health. While open data sharing undermines rights of Indigenous communities to govern data decisions, federated learning may facilitate secure and community-consented data sharing.
