Most systematic reviews that used the term "update" in title/abstract were not an updated version

OBJECTIVES

To analyze whether articles labelled as systematic reviews or meta-analyses (SRs/MAs) in the title and used terms "updated" or "update" in the title or abstract are indeed a report of an updated version of a previously existing SR/MA.

STUDY DESIGN AND SETTING

We searched PubMed for SRs/MAs, using descriptors updated/update in the title/abstract published in 2018-2019. We analyzed how the articles used the term "update"/"updated" and whether the previous version of SR was referenced. We surveyed authors who indicated that the SR was an updated version, but there was no reference to the original SR.

RESULTS

Among 1,118 included articles, most (N = 716; 64%) used the term "update" only to denote that an SR includes recent data. Among 47 authors eligible for survey, 15 replied (32%). Six authors (40%) stated that their article was an updated version and gave reference to the previous version, while 9 authors (60%) stated that their SR was not an updated version of a previous SR.

CONCLUSION

Most SRs that used the term "update" in title/abstract were not an updated version of an SR. Authors should use the descriptor "update"/"updated" in their title/abstract only to refer to a new version of an SR to avoid ambiguity.

Nomenclature: Herbal Taxonomy in the Global Commerce of Botanicals

In the world trade of medicinal plants, the naming of plants is fundamental to understanding which species are acceptable for therapeutic use. There are a variety of nomenclatural systems that are used, inclusive of common names, Latinized binomials, Galenic or pharmaceutical names, and pharmacopeial definitions. Latinized binomials are the primary system used for naming wild plants, but these alone do not adequately define medicinal plant parts. Each system has its specific applications, advantages, and disadvantages. The topic of medicinal plant nomenclature is discussed broadly by underscoring when and how varying nomenclatural systems should be used. It is emphasized that pharmacopeial definitions represent the only naming system that integrates plant identity, relevant plant parts, and the specific quality metrics to which a material must comply, thus affording the most appropriate identification method available for medicinal plant materials.

[Standardized computer recording of clinical pharmacy procedures in health care institution: Feedback and evaluation of potential economic value]

Clinical pharmacy procedures are clearly defined by the French society of clinical pharmacy. However, clinical pharmacists do not have efficient tools for their traceability. This need has increased following the publication of the instruction on the day hospital management of patients. Indeed, the action of the clinical pharmacist is included in it. In order to improve our traceability of clinical pharmacy acts and to take advantage of the implementation of the instruction, we worked with the medical information department to integrate our activity into their business software and to model the pathways valued by the intervention of the clinical pharmacist in outpatient care and in day hospital.

The Plasticene: Time and rocks

Plastics, "yesterday's hero... today's villain" or "the contemporary symbol of modernity," were invented in the early 20th century by Leo Hendrik Baekeland from macromolecules (resins, elastomers, and artificial fibres) of formaldehyde and phenol. This synthetic organic polymer took hold of daily human life and transformed the modern world with an ever-widening range of applications. Plastics are the third most-widely manufactured material in the world after cement and steel, and they have become widespread in our society with excessive production and consumption to meet demand. Plastics use is so dominant that they are inappropriately considered essential in the world consumers marketplace. Plastics are a clear indicator of the Anthropocene and can be considered the marker of the upper subdivision of this stage: the Plasticene.

Application of a Standardized Terminology and Nomenclature for Respiratory Cytology: Experience from a Large Tertiary Respiratory Cancer Centre

INTRODUCTION

In 2020, the World Health Organization-International Agency for Research on Cancer/International Academy of Cytology (WHO-IARC IAC) joint project was commenced to develop standardized nomenclature and diagnostic criteria in cytopathology internationally. Our institution has been coding all respiratory cytological specimens in a similar fashion for over 10 years. Our aim was to analyse the effectiveness of our respiratory cytology coding system by calculating the estimated risk of malignancy (ROM) and rates of each diagnostic category.

METHODS

Over a 2 year period, all endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), bronchial brushing, bronchial washing, bronchial lavage, and sputum specimens reported at our institution were analysed. For each specimen, the diagnostic code, the relevant indication for each diagnostic procedure, the diagnosis, and the presence or absence of a positive corresponding biopsy were recorded.

RESULTS

In total, 1,432 respiratory cytological specimens from 945 patients over a 2-year period were analysed. 467 specimens were confirmed to be associated with a malignant process. The overall ROM for respiratory cytology specimens was 37.7% for nondiagnostic, 18.1% for benign, 46.7% for atypical, 85.7% for suspicious for malignancy, and 91.9% for malignant. For each diagnostic procedure, the ROM increased from the benign to malignant categories.

DISCUSSION/CONCLUSION

Our ROM rates for overall respiratory cytology specimens and for EBUS-TBNA, bronchial brushing, and bronchial washing specimens separately are concordant with other major international studies. With the WHO-IARC IAC joint project in progress and an international respiratory cytology coding system being developed, our study has the potential to add value by providing indicative ROM rates, which can be used to inform the development of this new classification system. Our rates of diagnostic accuracy are in keeping with international standards, which support the accuracy of our data.

Heart failure with preserved ejection fraction: A distinct heart failure phenotype?

The present work discusses the serious confusion resulting from the arbitrary nomenclature of heart failure with preserved ejection fraction (HFpEF), the presumed underlying pathophysiology, and the supposed features. A consequence of this misconception is that HFpEF trials have recruited patients with entirely different characteristics rendering the extrapolation of the results of one study to the other infeasible and dramatically affecting diagnosis and treatment.

The importance of being the HGNC

The HUGO Gene Nomenclature Committee (HGNC) has been providing standardized symbols and names for human genes since the late 1970s. As funding agencies change their priorities, finding financial support for critical biomedical resources such as the HGNC becomes ever more challenging. In this article, we outline the key roles the HGNC currently plays in aiding communication and the need for these activities to be maintained.

International Consensus Recommendations for Eosinophilic Gastrointestinal Disease Nomenclature

BACKGROUND & AIMS

Substantial heterogeneity in terminology used for eosinophilic gastrointestinal diseases (EGIDs), particularly the catchall term "eosinophilic gastroenteritis," limits clinical and research advances. We aimed to achieve an international consensus for standardized EGID nomenclature.

METHODS

This consensus process utilized Delphi methodology. An initial naming framework was proposed and refined in iterative fashion, then assessed in a first round of Delphi voting. Results were discussed in 2 consensus meetings, and the framework was updated and reassessed in a second Delphi vote, with a 70% threshold set for agreement.

RESULTS

Of 91 experts participating, 85 (93%) completed the first and 82 (90%) completed the second Delphi surveys. Consensus was reached on all but 2 statements. "EGID" was the preferred umbrella term for disorders of gastrointestinal (GI) tract eosinophilic inflammation in the absence of secondary causes (100% agreement). Involved GI tract segments will be named specifically and use an "Eo" abbreviation convention: eosinophilic gastritis (now abbreviated EoG), eosinophilic enteritis (EoN), and eosinophilic colitis (EoC). The term "eosinophilic gastroenteritis" is no longer preferred as the overall name (96% agreement). When >2 GI tract areas are involved, the name should reflect all of the involved areas.

CONCLUSIONS

This international process resulted in consensus for updated EGID nomenclature for both clinical and research use. EGID will be the umbrella term, rather than "eosinophilic gastroenteritis," and specific naming conventions by location of GI tract involvement are recommended. As more data are developed, this framework can be updated to reflect best practices and the underlying science.

Rhipicephalus linnaei (Audouin, 1826) recognised as the "tropical lineage" of the brown dog tick Rhipicephalus sanguineus sensu lato: Neotype designation, redescription, and establishment of morphological and molecular reference

We re-describe the adult stages of Rhipicephalus linnaei (Audouin, 1826), and characterise its diagnostic molecular traits. A male R. linnaei collected in Esna City, Luxor Governorate, Egypt is designated as the neotype. Rhipicephalus linnaei is re-established as a valid tick name and removed from the synonymy list of Rhipicephalus sanguineus (Latreille, 1806). Rhipicephalus linnaei is most similar to R. sanguineus and Rhipicephalus camicasi Morel, Mouchet & Rodhain, 1976 because they share similar elongated comma-like spiracula that are narrowly visible dorsally, and the dorsal prolongation is narrower than the width of the adjacent festoon. The male of R. camicasi is distinguished from R. linnaei by the non-tapering caudal widening of the spiracula. The male of R. sanguineus is distinguished from R. linnaei by shorter extension that does not taper into a long narrow extension of the spiracula. The genital pore atrium of female R. linnaei is broadly U-shaped, while it is a narrower U-shape in R. sanguineus. The remaining species within the R. sanguineus species complex - Rhipicephalus sulcatus Neumann, 1908, Rhipicephalus turanicus Pomerantsev, 1940, Rhipicephalus guilhoni Morel & Vassilades, 1963, Rhipicephalus secundus Feldman-Muhsam, 1952 and Rhipicephalus afranicus Bakkes, 2020, all exhibit spiracula with the dorsal prolongation as wide as the adjacent festoon. The DNA sequence of R. linnaei is most closely related to R. guilhoni. The phylogenetic analysis of mitogenome (mtDNA) sequences including assembled mtDNA from whole genome sequencing of the neotype supports R. linnaei as a well-defined taxon when compared with DNA sequences of other species of the R. sanguineus species complex, in particular: R. sanguineus, R. turanicus, R. secundus and R. camicasi. Molecularly, R. linnaei belongs to the so-called R. sanguineus s.l. "tropical lineage" distributed globally including the Americas, Africa, Europe, Asia and is the only species from R. sanguineus species complex in Australia.

Recommendations for OCT Angiography Reporting in Retinal Vascular Disease: A Delphi Approach by International Experts

PURPOSE

To develop a consensus nomenclature for reporting OCT angiography (OCTA) findings in retinal vascular disease (e.g., diabetic retinopathy, retinal vein occlusion) by international experts.

DESIGN

Delphi-based survey.

SUBJECTS, PARTICIPANTS, AND/OR CONTROLS

Twenty-five retinal vascular disease and OCTA imaging experts.

METHODS, INTERVENTION, OR TESTING

A Delphi method of consensus development was used, comprising 2 rounds of online questionnaires, followed by a face-to-face meeting conducted virtually. Twenty-five experts in retinal vascular disease and retinal OCTA imaging were selected to constitute the OCTA Nomenclature in Delphi Study Group for retinal vascular disease. The 4 main areas of consensus were: definition of the parameters of "wide-field (WF)" OCTA, measurement of decreased vascular flow on conventional and WF-OCTA, nomenclature of OCTA findings, and OCTA in retinal vascular disease management and staging. The study end point was defined by the degree of consensus for each question: "strong consensus" was defined as ≥85% agreement, "consensus" as 80% to 84%, and "near consensus" as 70% to 79%.

MAIN OUTCOME MEASURES

Consensus and near consensus on OCTA nomenclature in retinal vascular disease.

RESULTS

A consensus was reached that a meaningful change in percentage of flow on WF-OCTA imaging should be an increase or decrease ≥30% of the absolute imaged area of flow signal and that a "large area" of WF-OCTA reduced flow signal should also be defined as ≥30% of the absolute imaged area. The presence of new vessels and intraretinal microvascular abnormalities, the foveal avascular zone parameters, the presence and amount of "no-flow areas," and the assessment of vessel density in various retinal layers should be added for the staging and classification of diabetic retinopathy. Decreased flow ≥30% of the absolute imaged area should define an ischemic central retinal vein occlusion. Several other items did not meet consensus requirements or were rejected in the final discussion round.

CONCLUSIONS

This study provides international consensus recommendations for reporting OCTA findings in retinal vascular disease, which may help to improve the interpretability and description in clinic and clinical trials. Further validation in these settings is warranted and ongoing. Efforts are continuing to address unresolved questions.

Advancing FDSTools by integrating STRNaming 1.1

The introduction of massively parallel sequencing in forensic analysis has been facilitated with typing kits, analysis software and allele naming tools such as the ForenSeq DNA Signature Prep (DSP) kit, FDSTools and STRNaming respectively. Here we describe how FDSTools 2.0 with integrated and refined STRNaming nomenclature was validated for implementation under ISO 17025 accreditation for the ForenSeq DSP kit. Newly-added options result in efficient automatic allele calling for the majority of markers while specific settings are applied for 'novel' sequence variants to avoid the calling of remaining variable noise observed in samples sequenced with the ForenSeq DSP kit that seem to arise in the PCR. Genome-wide built-in reference data allows for greatly simplified configuration of allele naming for human targets.

Naming of new natural products: Standard, pitfalls and tips-and-tricks

Naming a newly discovered natural product (NP) is a pleasant but difficult exercise. In most cases, the NP name will be given with reference to the species of origin, be it a plant, a marine organism, a mammalian or microbial species. For a long time, the use of biologically-based trivial names has been recommended to identify the parental linkage between the product and the originating genus or species. But the recommendation is not always followed and a multiplicity of trivial names have been attributed to NP, based on locations (country, region, city), foods, music, animals, forenames, etc. Tips-and-tricks associated with the naming of NP are underlined here. Usually, NP are differentiated across a homogeneous chemical series with a letter (from the Latin or Greek alphabet), followed or not with a number. In other cases, the change of a single letter distinguishes a series of NP. Common pitfalls associated with the naming of NP are enumerated, including the complexity of names, use of synonyms, duplicated names, confusing names and inappropriate terminology. The difficulties regularly encountered with the naming of NP are discussed. Four essential recommendations are recalled: (i) a thorough analysis of the existing products to avoid duplicated names and confusion, (ii) the use of a biologically-based trivial name to retrace the origin of the product, (iii) the strict adherence to the codes of chemical nomenclature, and (iv) the preference for simple names to facilitate transmission. Naming a new NP is a rewarding task, which shall be performed with all due skill, care and diligence.

The first reported case of accidental intestinal myiasis in a domestic dog by the flesh fly, Sarcophaga africa (Wiedeman, 1824)

Myiasis occurs when fly larvae, or maggots, feed on the tissue, secretions or digestive content of a live vertebrate. Here, a rare case of accidental intestinal or enteric myiasis is reported in a domestic dog. The species of fly is molecularly identified as Sarcophaga africa (Wiedeman, 1824) using the barcoding region of cytochrome oxidase I (COI). A brief critique on the usage of the term "pseudomyiasis" is provided and the complex taxonomy of S. africa is briefly summarised in order to shed light on the erroneous use of S. cruenata and S. haemorrhoidalis with obvious downstream effects. Finally, a comparative assessment to the limited cases in the literature is provided. These few cases are however highly fragmented and our understanding of accidental intestinal myiasis and the clinical manifestations thereof remain incomplete.

A world tour in the name of natural products

BACKGROUND

Names of natural products (NP) are usually given depending on the species of origin, be it a plant, a marine organism or a microbial species. In some cases, names have been given with reference to people, animals, music, foods or places. Many NP refer to countries, cities or specific places such as mountains, deserts, seas and oceans.

PURPOSE

On the basis of NP names, a world tour has been imagined referring to more than one hundred NP with names evocative of over 50 countries and regions.

RESULTS

The world tour goes from UK (britannin) to Italy (vaticanol) in Europe, from Uganda (ugandoside) to Senegal (senegalene, senegalenines) in Africa, from Brazil (brasilin) to Chile (santiaguine) in South America, from Utah (utahin) to Florida (floridanolide) in the US. It includes Central America (mexicanin, panamine) and the Caribbean islands (jamaicin, bahamaolides). It also crosses Alaska (alaskene) and Canada (quebecol, canadaline). The tour continues throughout Asia, from Thailand (thailandine) to China (Chinaldine) and Pakistan (pakistanamine), to finally reaches Oceania with Australia (australigenin) and Vanuatu (vanuatine), among other countries. This virtual journey, without bordure or wall, brings us to the highest mountains (himalayamine), the deepest oceans (pacificins) and the largest deserts (desertomycin).

CONCLUSION

In the current period of COVID-19 pandemia, with restricted opportunities for international travels, this NP name-based virtual journey offers a world tour to learn more from nature and to inspire scientists to contribute to the field of NP discovery and drug design. There are also limitations associated with the use of trivial names for NP. NP names can be further exploited for teaching and learning.

Diuretics: a contemporary pharmacological classification?

Diuretics are drugs that increase the flow of urine. They are commonly used to treat edema, hypertension, and heart failure. Typically, the pharmacological group consists of five classes: thiazide diuretics, loop diuretics, potassium-sparing diuretics, osmotic diuretics, and carbonic anhydrase inhibitors. This traditional classification and the nomenclature of diuretics have not changed over the last decades, which means that it was not adapted to current pharmacological research. Modern approaches in the field of pharmacological nomenclature suggest the introduction of mechanism-based drug class designations, which is not yet reflected in the group of diuretics. Moreover, included drug classes have lost their relevance as diuretic agents. Carbonic anhydrase inhibitors, for example, are mainly used in the treatment of glaucoma. Newer agents such as vasopressin-2 receptor antagonists or SGLT2 inhibitors possess diuretic properties but are not included in the pharmacological group. This review discusses the currentness of the pharmacological classification of diuretics. We elaborate changes in the field of nomenclature, the contemporary medical use of classical diuretics, and new diuretic agents.

Eliminate schizophrenia

“Schizophrenia” is used as a unitary diagnostic term for an illness that is extremely heterogeneous in its etiology, pathophysiology, presentation, and trajectory. Furthermore, the presence of psychosis—its hallmark characteristic—can be observed in individuals with other diagnoses, and biologically- and computationally-defined psychosis biotypes differ from those associated with DSM diagnoses and yield different treatment predictions. We argue that schizophrenia is not only stigmatizing as a label, it is not useful as a diagnostic term, a disease concept, or a construct for scientific research. Until we are able to delineate a range of dysfunctions across molecular/cellular and/or macrocircuit levels that map onto psychosis-proneness and indicate optimal treatment pathways, we propose to eliminate schizophrenia and replace it with a new nomenclature as an interim solution. Similar to what is done with other broad descriptive disease concepts in medicine which are defined by hallmark clinical features and then further subtyped (e.g., sickle cell anemia, iron deficiency anemia), we propose that psychosis spectrum illnesses (PSIs) be characterized by their temporal characteristics, relevant modifying/causal and symptom features, and treatment responsiveness.

Internal Carotid Artery Classification Systems: An Illustrative Review

The internal carotid artery (ICA) course has been discussed extensively. Several classification systems have attempted to delineate an accurate and helpful trajectory for microsurgical and endoscopic guidance, thus allowing a better neurosurgical performance while avoiding intraoperative complications. Also, the practicality of the classification systems has been emphasized for scholarly communication among disciplines. Nevertheless, the nomenclature of the ICA remains heterogeneous and confusing for health care professionals, trainees, and students. We present an illustrative review of 8 notable ICA classification systems using lateral and anterior views as a rapid tool for neuroanatomic consultation. The appraisal of the vessel anatomy from different perspectives while recognizing their usefulness and limitations might provide a comprehensive understanding of the ICA, optimize the intraoperative performance, and facilitate communication.

A review of menopause nomenclature

Menopause nomenclature varies in the scholarly literature making synthesis and interpretation of research findings difficult. Therefore, the present study aimed to review and discuss critical developments in menopause nomenclature; determine the level of heterogeneity amongst menopause definitions and compare them with the Stages of Reproductive Aging Workshop criteria. Definitions/criteria used to characterise premenopausal and postmenopausal status were extracted from 210 studies and 128 of these studies were included in the final analyses. The main findings were that 39.84% of included studies were consistent with STRAW classification of premenopause, whereas 70.31% were consistent with STRAW classification of postmenopause. Surprisingly, major inconsistencies relating to premenopause definition were due to a total lack of reporting of any definitions/criteria for premenopause (39.84% of studies). In contrast, only 20.31% did not report definitions/criteria for postmenopause. The present findings indicate that there is a significant amount of heterogeneity associated with the definition of premenopause, compared with postmenopause. We propose three key suggestions/recommendations, which can be distilled from these findings. Firstly, premenopause should be transparently operationalised and reported. Secondly, as a minimum requirement, regular menstruation should be defined as the number of menstrual cycles in a period of at least 3 months. Finally, the utility of introducing normative age-ranges as supplementary criterion for defining stages of reproductive ageing should be considered. The use of consistent terminology in research will enhance our capacity to compare results from different studies and more effectively investigate issues related to women's health and ageing.

Delirium disorder: Unity in diversity

OBJECTIVE

The first objective of this review is to explore the factors that have led to and maintain the division between delirium and acute encephalopathy. The second is to explore the value of harmonizing them through the model of delirium disorder.

METHOD

This narrative review outlines major distinctions between delirium and acute encephalopathy. It also compares them with the model of delirium disorder, which seeks not only to integrate them but also to offer a broader palette of treatment targets.

RESULTS

Delirium implies an underlying acute encephalopathy, whereas acute encephalopathy presents as a spectrum from subsyndromal delirium to coma. Key factors that differentiate these two models include tradition, nuances of the models themselves, linguistic connotations, evoked responses from clinicians, implications of preventability and responsibility, cultural perceptions of non-pharmacological vs pharmacological interventions and economic incentives. A validated set of pathophysiological subtypes may ultimately help link the delirium-spectrum phenotype with various acute encephalopathies.

CONCLUSIONS

Developing a coherent clinical and scientific approach to this set of conditions demands that we first develop a coherent understanding of the conditions themselves and how they relate to one another. Such an approach must embrace the tension between a convergent phenotype and its diverse biological underpinnings.

Therapeutic Antibodies: An Overview

Polyclonal immunoglobulin (Ig) preparations have been used for several decades for treatment of primary and secondary immunodeficiencies and for treatment of some infections and intoxications. This has demonstrated the importance of Igs, also called antibodies (Abs) for prevention and elimination of infections. Moreover, elucidation of the structure and functions of Abs has suggested that they might be useful for targeted treatment of several diseases, including cancers and autoimmune diseases. The development of technologies for production of specific monoclonal Abs (MAbs) in large amounts has led to the production of highly effective therapeutic antibodies (TAbs), a collective term for MAbs (MAbs) with demonstrated clinical efficacy in one or more diseases. The number of approved TAbs is currently around hundred, and an even larger number is under development, including several engineered and modified Ab formats. The use of TAbs has provided new treatment options for many severe diseases, but prediction of clinical effect is difficult, and many patients eventually lose effect, possibly due to development of Abs to the TAbs or to other reasons. The therapeutic efficacy of TAbs can be ascribed to one or more effects, including binding and neutralization of targets, direct cytotoxicity, Ab-dependent complement-dependent cytotoxicity, Ab-dependent cellular cytotoxicity or others. The therapeutic options for TAbs have been expanded by development of several new formats of TAbs, including bispecific Abs, single domain Abs, TAb-drug conjugates, and the use of TAbs for targeted activation of immune cells. Most promisingly, current research and development can be expected to increase the number of clinical conditions, which may benefit from TAbs.

Laboratory Codes in Nomenclature and Scientific Communication (Advancing Organism Nomenclature in Scientific Communication to Improve Research Reporting and Reproducibility)

Laboratory registration codes, also known as laboratory codes or lab codes, are a key element in standardized laboratory animal and genetic nomenclature. As such they are critical to accurate scientific communication and to research reproducibility and integrity. The original committee on Mouse Genetic Nomenclature published nomenclature conventions for mice genetics in 1940, and then conventions for inbred strains in 1952. Unique designations were needed, and have been in use since the 1950s, for the sources of animals and substrains, for the laboratories that identified new alleles or mutations, and then for developers of transgenes and induced mutations. Current laboratory codes are typically a 2- to 4-letter acronym for an institution or an investigator. Unique codes are assigned from the International Laboratory Code Registry, which was developed and is maintained by ILAR in the National Academies (National Academies of Sciences Engineering and Medicine and previously National Academy of Sciences). As a resource for the global research community, the registry has been online since 1997. Since 2003 mouse and rat genetic and strain nomenclature rules have been reviewed and updated annually as a joint effort of the International Committee on Standardized Genetic Nomenclature for Mice and the Rat Genome and Nomenclature Committee. The current nomenclature conventions (particularly conventions for non-inbred animals) are applicable beyond rodents, although not widely adopted. Ongoing recognition, since at least the 1930s, of the research relevance of genetic backgrounds and origins of animals, and of spontaneous and induced genetic variants speaks to the need for broader application of standardized nomenclature for animals in research, particularly given the increasing numbers and complexities of genetically modified swine, nonhuman primates, fish, and other species.

Nonalcoholic Fatty Liver Disease (NAFLD) Name Change: Requiem or Reveille?

Nonalcoholic fatty liver disease (NAFLD) affects about a quarter of the world's population and poses a major health and economic burden globally. Recently, there have been hasty attempts to rename NAFLD to metabolic-associated fatty liver disease (MAFLD) despite the fact that there is no scientific rationale for this. Quest for a "positive criterion" to diagnose the disease and destigmatizing the disease have been the main reasons put forth for the name change. A close scrutiny of the pathogenesis of NAFLD would make it clear that NAFLD is a heterogeneous disorder, involving different pathogenic mechanisms of which metabolic dysfunction-driven hepatic steatosis is only one. Replacing NAFLD with MAFLD would neither enhance the legitimacy of clinical practice and clinical trials, nor improve clinical care or move NAFLD research forward. Rather than changing the nomenclature without a strong scientific backing to support such a change, efforts should be directed at understanding NAFLD pathogenesis across diverse populations and ethnicities which could potentially help develop newer therapeutic options.

The Arcuate Fasciculus and language origins: Disentangling existing conceptions that influence evolutionary accounts

The Arcuate Fasciculus (AF) is of considerable interdisciplinary interest, because of its major implication in language processing. Theories about language brain evolution are based on anatomical differences in the AF across primates. However, changing methodologies and nomenclatures have resulted in conflicting findings regarding interspecies AF differences: Historical knowledge about the AF originated from human blunt dissections and later from monkey tract-tracing studies. Contemporary tractography studies reinvestigate the fasciculus' morphology, but remain heavily bound to unclear anatomical priors and methodological limitations. First, we aim to disentangle the influences of these three epistemological steps on existing AF conceptions, and to propose a contemporary model to guide future work. Second, considering the influence of various AF conceptions, we discuss four key evolutionary changes that propagated current views about language evolution: 1) frontal terminations, 2) temporal terminations, 3) greater Dorsal- versus Ventral Pathway expansion, 4) lateralisation. We conclude that new data point towards a more shared AF anatomy across primates than previously described. Language evolution theories should incorporate this continuous AF evolution across primates.
