BACKGROUND
Examination of the mortality patterns in the United States among racial, ethnic, and age groups attributed to the 1918-19 influenza pandemic revealed stark disparities, causes for which could have been addressed and rectified this past century. However, these disparities have been amplified during the current COVID-19 pandemic.We have ignored the lessons of the past, and were destined to repeat its failings.
OBJECTIVES
Compare and contrast mortality patterns by age, race, and ethnicity attributable to the 1918-19 influenza pandemic in the United States with corresponding patterns during the COVID-19 pandemic.
METHODS
This is a retrospective study, establishing mortality rates according to age, race and ethnicity attributable to the 1918-19 influenza pandemic in the United States and to the current COVID-19 pandemic, using mortality data published by the U.S. Public Health Service and the Centers for Disease Control and Prevention. Negative binomial regression models were used to establish rate ratios, that is, ratios of mortality rates across the various racial/ethnic groups, and associated 95% confidence intervals.
RESULTS
Mortality patterns by age differ significantly between the 1918-19 influenza pandemic and the COVID-19 pandemic: with infant and young adult (25-40 years old) mortality substantially higher in the former. Disparities in mortality between racial and ethnic groups are amplified in the COVID-19 pandemic compared to the 1918-19 experience.
CONCLUSIONS
As we evaluate our nation's response to COVID-19 and design public policy to prepare better for coming pandemics, we cannot ignore the stark disparities in mortality rates experienced by different racial and ethnic groups. This will require a sustained resolve by society and government to delineate and remedy the causative factors, through science devoid of political interpretation and exploitation.

OBJECTIVE
The purpose of this study is to evaluate the rate of duplicate publication in radiology journals. The secondary objective is to evaluate the sensitivity of iThenticate.
MATERIALS AND METHODS
From January 1993 to December 2013, Déjà Vu (a database of highly similar citations) and PubMed were used to search for similar citations in 53 radiology journals. Citations were screened independently by two reviewers and verified by a third using predefined criteria to determine true cases of duplicate publication. The overall rate of duplicate publication was calculated; analysis of rate by journal, impact factor, and publication year was performed. The sensitivity of iThenticate was evaluated by analyzing all identified duplicate publications.
RESULTS
From 128,818 citations in the included journals, 1786 (Déjà Vu) and 104 (PubMed) were flagged as potential duplicates. Of these, 248 (226 from Déjà Vu and 22 from PubMed) were classified as true duplicate publications after application of our criteria. The overall rate was 1.92/1000 citations; it varied widely across journals from zero to over 10/1000 citations, showed no correlation with impact factor (R(2) = 0.06; p = 0.093), and no change over time (R(2) = 0.28; p = 0.515). iThenticate flagged 153 of 248 (61.9%) duplicates as "possible duplicates" (defined as overall percentage match > 30%) and identified the corresponding duplicate citation pair in 140 of 248 (56.7%) cases; in 98 of these, the duplicate citation pair was the highest percentage similarity match.
CONCLUSION
Duplicate publications in radiology journals are uncommon. The rate varies widely between journals, but was not associated with journal impact factor and did not change over time. iThenticate shows promise for identification of duplicate publications; however, refinements may be necessary to maximize its effectiveness.

Review
The amygdala contributes to the generation and propagation of epileptiform activity in temporal lobe epilepsy (TLE). Ictal symptoms such as fear, dreamy states (déjà vu, memory flashbacks, experiential hallucinations), epigastric auras, or sympathetic outflow with cardiovascular changes are often linked to a seizure focus in the amygdala. However, the amygdala may also play a role in comorbid anxiety, depression, and other psychiatric symptoms experienced in the interictal phase, especially in pharmacoresistant TLE. The few studies available on TLE-related alterations in surgical amygdala specimens indicate loss of both excitatory spiny projection neurons as well as interneurons in nuclei with a cortex-like architecture, which may influence mechanisms of feedforward and feedback inhibition. Studies of the human amygdala indicate global alterations in the density of AMPA/kainate, metabotropic glutamate, γ-aminobutyric acid type A (GABAA ), muscarinic M2 and M3, serotonergic 5-HT1A, and adrenergic α1 receptors. Also, amygdala GABAergic and neuropeptide Y (NPY) systems affected in human TLE are both involved in antiepileptic and anxiolytic effects. Experimental and human positron emission tomography studies indicate changes in amygdala serotonergic, NPY Y1 receptor, neurokinin, and opioid systems in emotional disturbances in TLE. Of particular interest is the reduction in amygdala volume in conjunction with ictal fear, seizure focus in the amygdala, and amygdala and hippocampal sclerosis in TLE patients. In contrast, patients with interictal depression often have an intact or even enlarged amygdala and a negative MRI associated with amygdala hypometabolism, which can be associated with limbic autoimmune encephalitis. These findings suggest a differential role of TLE-related amygdala changes in ictal and interictal emotional disturbances.

Barzykowski and Moulin argue that common memory processes form the basis of involuntary autobiographical memory and the déjà vu experience. We think that they underemphasize the potential dissociability between processes that enact retrieval and the processes that produce conscious experience. We propose that retrieval and conscious experience result from different processes in both involuntary autobiographical memory and déjà vu experiences.

Several studies pertaining to déjà vu have consistently made a connection with the perirhinal region, a region located below the hippocampus. This idea is strengthened by the fact that déjà vu is an erroneous sense of familiarity and that familiarity appears to largely depend on the perirhinal region in healthy subjects. In this context, the role of the hippocampus is particularly unclear as it is unknown whether or not it plays a role in the genesis of déjà vu. We report on the case of OHVR, an epileptic patient who suffers from severe episodic amnesia related to massive isolated bilateral damage to the hippocampus. In contrast, the perirhinal region is intact structurally and functionally. This patient reports frequent déjà vu but also another experiential phenomenon with a prominent feeling of prescience, which shows some of the characteristics of déjà vécu. She clearly distinguishes both. She also developed a form of synaesthesia by attributing affective valence to numbers. This study shows that déjà vu can occur in cases of amnesia with massively damaged hippocampi and confirms that the perirhinal region is a core region for déjà vu, using a different approach from previous reports. It also provides clues about a potential influence of hippocampal alterations in déjà vécu.

Little is known about how people characterise and classify the experience of déjà vu. The term déjà vu might capture a range of different phenomena and people may use it differently. We examined the description of déjà vu in two languages: French and English, hypothesising that the use of déjà vu would vary between the two languages. In French, the phrase déjà vu can be used to indicate a veridical experience of recognition - as in "I have already seen this face before". However, the same is not true in English. In an online questionnaire, we found equal rates of déjà vu amongst French and English speakers, and key differences in how the experience was described. As expected, the French group described the experience as being more frequent, but there was the unexpected finding that they found it to be more troubling.

I propose a model that places episodic, semantic, and other commonly studied forms of memory into the same conceptual space. The space is defined by three dimensions required for Tulving's episodic and semantic memory. An implicit-explicit dimension contrasts both episodic and semantic memory with common forms of implicit memory. A self-reference dimension contrasts episodes that occurred to one person with semantic knowledge. A scene dimension contrasts episodes that occurred in specific contexts with context-free semantic information. The three dimensions are evaluated against existing behavioral and neural evidence to evaluate both the model and the concepts underlying the study of human memory. Unlike a hierarchy, which has properties specific to each category, the dimensions have properties that extend throughout the conceptual space. Thus, the properties apply to all forms of existing and yet-to-be-discovered memory within the space. Empty locations in the proposed space are filled with existing phenomena that lack a clear place in current theories of memory, including reports of episodic-like memories for events reported to but not witnessed by a person, fictional narrative accounts, déjà vu, and implicit components contributing to personality, the self, and autobiographical memory.
