ABSTRACT

Six luminescent europium organic complexes have been synthesized and studied for their luminescent properties. The synthesized complexes were analyzed through elemental analysis, XRD, SEM, EDAX, FT-IR, NMR and thermogravimetry. The complexes exhibit crystalline behavior and possess decent thermal stability. Photoluminescence study on complexes were conducted in both solid and solution states, the results indicate the characteristic red emission. With the addition of ancillary ligands, water molecules are replaced from inner coordination sphere, leading to enhanced luminescence properties. The colorimetric parameters (CIE, CP%, CCT, u', v') suggest aptness of these complexes in red light illuminating OLEDs. The J-O parameters were calculated experimentally and theoretically with the help of LUMPAC software. Theoretical and experimental results agree well reflecting the efficacy of the outcomes. As a result of red emission, these complexes could have interesting photonics applications. The biological studies indicate the probable use of these complexes in the medical industry.

ABSTRACT

One of the main challenges in food microbiology is to prevent the risk of outbreaks by avoiding the distribution of food contaminated by bacteria. This requires constant monitoring of the circulating strains throughout the food production chain. Bacterial genomes contain signatures of natural evolution and adaptive markers that can be exploited to better understand the behavior of pathogen in the food industry. The monitoring of foodborne strains can therefore be facilitated by the use of these genomic markers capable of rapidly providing essential information on isolated strains, such as the source of contamination, risk of illness, potential for biofilm formation, and tolerance or resistance to biocides. The increasing availability of large genome datasets is enhancing the understanding of the genetic basis of complex traits such as host adaptation, virulence, and persistence. Genome-wide association studies have shown very promising results in the discovery of genomic markers that can be integrated into rapid detection tools. In addition, machine learning has successfully predicted phenotypes and classified important traits. Genome-wide association and machine learning tools have therefore the potential to support decision-making circuits intending at reducing the burden of foodborne diseases. The aim of this chapter review is to provide knowledge on the use of these two methods in food microbiology and to recommend their use in the field.

ABSTRACT

Inflammatory bowel disease is a multifaceted condition that is influenced by nutritional, microbial, environmental, genetic, psychological, and immunological factors. Polyphenols and polysaccharides have gained recognition for their therapeutic potential. This review emphasizes the biological effects of polyphenols and polysaccharides, and explores their antioxidant, anti-inflammatory, and microbiome-modulating properties in the management of inflammatory bowel disease (IBD). However, polyphenols encounter challenges, such as low stability and low bioavailability in the colon during IBD treatment. Hence, polysaccharide-based encapsulation is a promising solution to achieve targeted delivery, improved bioavailability, reduced toxicity, and enhanced stability. This review also discusses the significance of covalent and non-covalent interactions, and simple and complex encapsulation between polyphenols and polysaccharides. The administration of these compounds in appropriate quantities has proven beneficial in preventing the development of Crohn's disease and ulcerative colitis, ultimately leading to the management of IBD. The use of polyphenols and polysaccharides has been found to reduce histological scores and colon injury associated with IBD, increase the abundance of beneficial microbes, inhibit the development of colitis-associated cancer, promote the production of microbial end-products, such as short-chain fatty acids (SCFAs), and improve anti-inflammatory properties. Despite the combined effects of polyphenols and polysaccharides observed in both in vitro and in vivo studies, further human clinical trials are needed to comprehend their effectiveness on inflammatory bowel disease.

ABSTRACT

Mercury ion (Hg2+) is considered a harmful neurotoxin, and real-time monitoring of Hg2+ concentrations in environmental and biological samples is critical. Fluorescent probes are a rapidly emerging visualization tool owing to their simple design and good selectivity. Herein, a novel fluorescence (FL) probe 2-(4-((6-((quinolin-8-yloxy)methyl)pyridin-2-yl)methyl)piperazin-1-yl)anthracene-9,10-dione (QPPA) is designed using piperazine as a linker between the anthraquinone group, which serves as a fluorophore, and N4O as the Hg2+ ligand. The probe exhibits FL "turn-on" sensing of Hg2+ because the complex inhibits the photo-induced electron transfer (PET) process. Moreover, QPPA can overcome the invasion by other possible cations, resulting in a clear color change from orange to colorless with the addition Hg2+. The chelation of QPPA with Hg2+ in a 1:1 ratio. Subsequently, the theoretically determined binding sites of the ligand to Hg2+ are validated through 1H NMR titration. The in situQPPA-Hg2+ complex can be subjected to Hg2+ extraction following the introduction of S2- owing to its robust binding capacity. The exceptional limit of detection values for Hg2+ and S2- are obtained as 63.0 and 79.1 nM (S/N = 3), respectively. Moreover, QPPA can display bright red FL in the presence of Hg2+ in different biological specimens such as HeLa cells, zebrafish, onion root tip tissues, and water flea Daphnia carinata, further providing an effective strategy for environmental monitoring and bioimaging of Hg2+ in living organisms.

ABSTRACT

Regions of Homozygosity (ROH) typically reflect normal demographic history of a human population, but may also relate to cryptic consanguinity, and, additionally, have been associated with specific medical conditions. The objective of this study was to investigate the location, size, and prevalence of common ROH segments in a Middle Eastern cohort. This retrospective study included 13 483 samples collected from all Chromosomal Microarray analyses (CMA) performed using Single Nucleotide Polymorphism (SNP) arrays at the genetic clinical laboratory of Rabin Medical Center between 2017-2023 (primary data set). An additional replication cohort including 100 842 samples from another SNP array platform, obtained from Maccabi Health Organization, was analyzed. Common ROH locations were defined as those ROH locations involving 1% or more of the samples. A total of 66 710 ROH segments, involving 13 035 samples (96.7%) were identified in the primary data set. Of the 4069 cytogenetic ROH locations, 68 were identified as common. The prevalence of non-common ROH was relatively high in affected individuals, and for acrocentric chromosomes, chromosomes associated with common trisomies, and non-imprinted chromosomes. In addition, differences in common ROH locations were observed between the primary and the replication cohorts. Our findings highlight the need for population-specific guidelines in determining ROH reporting cutoffs, considering factors such as population-specific prevalence and testing platform differences. Future research with larger, varied cohorts is essential to advance understanding of ROH's associations with medical conditions and to improve clinical practices accordingly.

ABSTRACT

Hematopoiesis is the process that generates the cells of the blood and immune system from hematopoietic stem and progenitor cells (HSPCs) and represents the system with the most rapid cell turnover in a mammalian organism. HSPC differentiation trajectories, their underlying molecular mechanisms, and their dysfunctions in hematologic disorders are the focal research questions of experimental hematology. While HSPC transplantations in murine models are the traditional tool in this research field, recent advances in genome editing and next generation sequencing resulted in the development of many fundamentally new approaches for the analyses of mammalian hematopoiesis in situ and at single cell resolution. The current review will cover many recent developments in this field in murine models, from the bulk lineage tracing studies of HSPC differentiation to the barcoding of individual HSPCs with Cre-recombinase, Sleeping Beauty transposase, or CRISPR/Cas9 tools, to map hematopoietic cell fates, together with their transcriptional and epigenetic states. We also address studies of the clonal dynamics of human hematopoiesis, from the tracing of HSPC clonal behaviours based on viral integration sites in gene therapy patients to the recent analyses of unperturbed human hematopoiesis based on naturally accrued mutations in either nuclear or mitochondrial genomes. Such studies are revolutionizing our understanding of HSPC biology and hematopoiesis both under homeostatic conditions and in the response to various forms of physiological stress, reveal the mechanisms responsible for the decline of hematopoietic function with age, and in the future may advance the understanding and management of the diverse disorders of hematopoiesis.

ABSTRACT

This study investigates baseline differences in couples enrolled in the "It Takes Two" HIV prevention intervention for transgender women and their partners, comparing in-person participation pre-COVID-19 and digital participation during the pandemic. Among 52 couples (40% in-person, 60% digital), bivariate analyses revealed that in-person participants were more likely to be African American, have cisgender male partners, report higher unemployment, incarceration histories, greater relationship stigma, and lower relationship quality. The findings highlight the limitations of digital modalities in engaging transgender women of color and those with structural vulnerabilities. The study emphasizes that reliance on digital methods in HIV research jeopardizes the inclusion of those lacking technological access and literacy, especially communities disproportionately impacted by HIV. Researchers must incorporate hybrid or in-person options and engage communities to ensure equity and inclusion, thus overcoming barriers and ensuring comprehensive population reach in HIV prevention studies.

ABSTRACT

BACKGROUND: It is unknown if gastric adenocarcinoma survivors have longer, shorter, or similar survival compared to the background population. This knowledge could contribute to evidence-based monitoring strategies, healthcare recommendations, and information for patients and families. METHODS: This population-based cohort study included all patients who underwent gastrectomy for gastric adenocarcinoma between 2006-2015 in Sweden and survived ≥ 5 years after surgery. They were followed up until death, postoperative year 10, or end of study period (31 December, 2020). Division of the observed by the expected survival yielded relative survival rates with 95% confidence intervals (CIs) using the life table method. The expected survival was derived from the entire Swedish population of the corresponding age, sex, and calendar year. Data came from medical records and nationwide registers. RESULTS: The survival among all 767 gastric adenocarcinoma survivors was shorter than the expected. The reduction in relative survival increased for each follow-up year, from 97.3% (95% CI 95.4-99.1%) year 6 to 86.6% (95% CI 82.3-90.9%) year 10. The decline in relative survival was more pronounced among patients who had gastrectomy in earlier calendar years (82.9% [95% CI 77.4-88.4%] year 10 for years 2011-2015), shorter education (85.2% [95% CI 77.4-93.0%] year 10 for education ≤ 9 years), more comorbidities (78.0% [95% CI 63.9-92.0%] year 10 for Charlson comorbidity score ≥ 2), and no neoadjuvant therapy (83.2% [95% CI 77.4-89.0%] year 10). CONCLUSION: Gastric adenocarcinoma survivors seem to have poorer survival than the corresponding background population, particularly in certain subgroups.

ABSTRACT

Since the reports of the first cases of COVID-19, in less than 5 years, a huge number of documents regarding that disease and the coronavirus (SARS-CoV-2), responsible for the infection, have been published. The tremendous number of scientific documents covers many topics on different issues directly related to COVID-19/SARS-CoV-2. The number of articles-including reviews-reporting adverse/side effects of the approved COVID-19 vaccines is considerable. A wide range of adverse/side effects have been reported in humans after COVID-19 vaccination: thrombotic events/thrombocytopenia, myocarditis/pericarditis, cutaneous reactions, immune-mediated effects, psychiatric adverse events, systemic lupus erythematosus, reproductive toxicity, and other miscellaneous adverse effects. In contrast, information on nonclinical studies conducted to assess the potential toxicity/adverse effects of the COVID-19 vaccines in laboratory animals, is comparatively very scarce. The present review was aimed at revising the scientific literature regarding the studies in laboratory animals on the toxic/adverse effects of COVID-19 vaccines. In addition, the investigations reported in those specific toxicology journals with the highest impact factors have been examined one by one. The results of the present review indicate that most nonclinical/experimental studies on the adverse/toxic effects of the COVID-19 vaccines and/or potential candidates showed-in general terms-a good safety profile. Only in some animal studies were certain adverse effects found. However, a rather surprising result has been the limited number of available (in the databases PubMed and Scopus) nonclinical studies performed by the companies that have been the largest manufacturers of mRNA vaccines in the world. It is assumed that these studies have been conducted. However, they have not been published in scientific journals, which does not allow the judgment of the international scientific community, including toxicologists.

ABSTRACT

Background: This research concerns improving the National Health Service health services trans adults need. These include the national specialist Gender Identity Clinics that support people making a medical transition. Not all trans people need to make a medical transition, and transition can take many different paths. Waits to be seen by Gender Identity Clinics are, however, several years long, and there may be significant problems of co-ordination between different aspects of transition-related care, and between transition-related care and general health care. Objectives: The main objectives were to understand: Which factors make services more or less accessible and acceptable to the variety of trans adults? How initiatives for providing more person-centred and integrated care can be successfully implemented and further improved? Design, data sources and participants: An online and paper screening survey was used to gather data on demographics and service use of trans people across the United Kingdom, with 2056 responses. Researchers used survey data to construct five purposive subsamples for individual qualitative interviews, identifying groups of people more likely to experience social exclusion or stigma. There were 65 online interviews. In addition, 23 trans Black people and people of colour attended focus groups. Six case studies were completed: four on initiatives to improve care and two on experiences of particular trans populations. Fifty-five service provider staff and 45 service users were interviewed. Results: The following undermine person-centred co-ordinated care and can lead to experiences of harm: lack of respectful treatment of trans people by general practitioner practices; inadequate funding of services; lack of support during waiting; the extended and challenging nature of Gender Identity Clinic diagnostic assessments, sometimes experienced as adversarial; breakdowns in collaboration between Gender Identity Clinics and general practitioner practices over hormone therapy; lack of National Health Service psychological support for trans people. Case studies indicated ways to improve care, although each has significant unresolved issues: training in trans health care for general practitioners; third-sector peer-support workers for trans people who come to National Health Services; gender services taking a collaborative approach to assessing what people need, clarifying treatment options, benefits and risks; regional general practitioner-led hormone therapy clinics, bringing trans health care into the mainstream; psychology services that support trans people rather than assess them. Limitations: Some contexts of care and experiences of particular groups of trans people were not addressed sufficiently within the scope of the project. While efforts were made to recruit people subject to multiple forms of stigma, there remained gaps in representation. Conclusions and future work: The findings have significant implications for commissioners and providers of existing National Health Services gender services, including recently established pilot services in primary care. In particular they point to the need for assessments for access to transition care to be more collaborative and culturally aware, implying the value of exploring informed consent models for accessing transition-related care. Further research is needed to investigate how far the findings apply with particular subpopulations. Study registration: This study is registered as Research Registry, no. 5235. Funding: This award was funded by the National Institute for Health and Care Research (NIHR) Health and Social Care Delivery Research programme (NIHR award ref: 17/51/08) and is published in full in Health and Social Care Delivery Research; Vol. 12, No. 28. See the NIHR Funding and Awards website for further award information.


This research concerns improving the range of National Health Service health services that trans adults need. Trans people have a different gender from that assigned at birth or in early childhood. Not all need to make a medical transition to express their gender, and transition can take many different forms, including hormone therapy, various kinds of surgery, and other procedures such as hair removal. At the time of writing, trans people over 17 who need to make a medical transition can seek care at one of the United Kingdom's 10 specialist National Health Service Gender Identity Clinics. However, people must wait a very long time before they are seen. Through 110 in-depth interviews, as well as focus groups attended by 23 people, this research explored recent experiences of trans people receiving various kinds of health care. A further 55 interviews investigated the views of National Health Service and voluntary-sector staff involved in delivering trans health care. All of this has led to insights about how services can be improved, and the development of online courses for healthcare staff and for people who use services or support those who use services. The research indicates what can lead to experiences of poor care that is not 'joined up': lack of respectful treatment of trans people by general practitioner practices; inadequate funding of services; lack of support while waiting; the extended and difficult nature of Gender Identity Clinic diagnostic assessments; breakdowns in collaboration between Gender Identity Clinics and general practitioner practices over hormone therapy; lack of National Health Service psychological support for trans people. The research indicates some important ways to improve care: training in trans health care for general practitioners; third-sector peer-support workers for trans people who come to National Health Service services; gender services taking a collaborative approach to assessing what people need, clarifying treatment options, benefits and risks; regional general practitioner-led hormone therapy clinics, bringing trans health care into the mainstream; psychology services that support trans people rather than assessing them.

ABSTRACT

Cadmium (Cd) is a dangerous environmental contaminant. Jute (Corchorus sp.) is an important natural fiber crop with strong absorption and excellent adaptability to metal-stressed environments, used in the phytoextraction of heavy metals. Understanding the genetic and molecular mechanisms underlying Cd tolerance and accumulation in plants is essential for efficient phytoremediation strategies and breeding novel Cd-tolerant cultivars. Here, machine learning (ML) and hyperspectral imaging (HSI) combining genome-wide association studies (GWAS) and RNA-seq reveal the genetic basis of Cd resistance and absorption in jute. ML needs a small number of plant phenotypes for training and can complete the plant phenotyping of large-scale populations with efficiency and accuracy greater than 90%. In particular, a candidate gene for Cd resistance (COS02g_02406) and a candidate gene (COS06g_03984) associated with Cd absorption are identified in isoflavonoid biosynthesis and ethylene response signaling pathways. COS02g_02406 may enable plants to cope with metal stress by regulating isoflavonoid biosynthesis involved in antioxidant defense and metal chelation. COS06g_03984 promotes the binding of Cd2+ to ETR/ERS, resulting in Cd absorption and tolerance. The results confirm the feasibility of high-throughput phenotyping for studying plant Cd tolerance by combining HSI and ML approaches, facilitating future molecular breeding.

ABSTRACT

OBJECTIVES: This study aimed to investigate the association between age-specific and sex-specific continuous metabolic syndrome severity score (cMetS-S) and the risk of developing type 2 diabetes mellitus (T2DM). Additionally, the study aimed to assess the added value of cMetS-S in predicting T2DM compared with traditional MetS criteria. DESIGN: The study used a longitudinal cohort design, following participants for 18 years. SETTING: The research was conducted within the Tehran Lipid and Glucose Study, a community-based study in Tehran, Iran. PARTICIPANTS: A total of 6957 participants aged 20-60 years were included in the study. INTERVENTIONS/EXPOSURES: The cMetS-S of each participant was determined using age-specific and sex-specific equations and Cox proportional hazard regression models were used to analyse the association between cMetS-S and T2DM using continuous and quantile approaches. PRIMARY AND SECONDARY OUTCOME MEASURES: The outcome measure was the association between cMetS-S and the development of T2DM during the 18-year follow-up. RESULTS: A total of 1124 T2DM cases were recorded over 18 years of follow-up. In the fully adjusted model, a 1-SD increase in the cMetS-S was associated with future T2DM (HR 1.72; 95% CI 1.54 to 1.91). Men and women had HRs of 1.65 (95% CI 1.40 to 1.95) and 1.83 (95% CI 1.59 to 2.10) for T2DM per 1-SD increase in cMetS-S, respectively. Higher cMetS-S was associated with increased risk of diabetes in both prediabetic (HR 1.42;95% CI 1.23 to 1.64) and normoglycaemic individuals (HR 2.11;95% CI 1.76 to 2.54); this association was more significant in normoglycaemic individuals. Unlike the traditional-based MetS definitions, the cMetS-S improved diabetes prediction (p<0.001). CONCLUSIONS: The cMetS-S is strongly associated with future diabetes in prediabetic and normoglycaemic individuals independent of MetS components during a long term. As the relationship between cMetS-S and T2DM is more pronounced in normoglycaemic individuals than in those with pre-diabetes, implementing the evaluation of cMetS-S can serve as an early identification tool for individuals at risk of T2DM prior to the onset of pre-diabetes.

ABSTRACT

OBJECTIVES: We aim to evaluate estimated glomerular filtration rate (eGFR) patterns of progression in a multiethnic cohort of people with type I diabetes mellitus and with baseline eGFR ≥45 mL/min/1.73 m2. DESIGN: Observational cohort. SETTING: People with a clinical diagnosis of type 1 diabetes, attending two university hospital-based outpatient diabetes clinics, in South London between 2004 and 2018. PARTICIPANTS: We studied 1495 participants (52% females, 81% white, 12% African-Caribbean and 7% others). PRIMARY AND SECONDARY OUTCOME MEASURES: Clinical measures including weight and height, systolic blood pressure, diastolic blood pressure and laboratory results (such as serum creatinine, urine albumin to creatinine ratio (ACR), HbA1c were collected from electronic health records (EHRs) and eGFR was estimated by the Chronic Kidney Disease-Epidemiology Collaboration. Ethnicity was self-reported. RESULTS: Five predominantly linear patterns/groups of eGFR trajectories were identified. Group I (8.5%) had a fast eGFR decline (>3 mL/min/1.73 m2 year). Group II (23%) stable eGFR, group III (29.8%), groups IV (26.3%) and V (12.4%) have preserved eGFR with no significant fall. Group I had the highest proportion (27.6%) of African-Caribbeans. Significant differences between group I and the other groups were observed in age, gender, HbA1C, systolic and diastolic blood pressure, body mass index, cholesterol and urine ACR, p<0.05 for all. At 10 years of follow-up, 33% of group I had eGFR <30 and 16.5%<15 (mL/min/1.73 m2). CONCLUSIONS: Distinct trajectories of eGFR were observed in people with type 1 diabetes. The group with the highest risk of eGFR decline had a greater proportion of African-Caribbeans compared with others and has higher prevalence of traditional modifiable risk factors for kidney disease.

ABSTRACT

BACKGROUND: Biliary dilatation without obvious etiology on cross sectional imaging warrants further investigation. This study aimed to assess yield of endoscopic ultrasound in providing etiologic diagnosis in such situation. METHODS: Prospective cohort of consecutive patients with biliary dilatation & non diagnostic computed tomography (CT) and /or magnetic resonance imaging (MRI) underwent endoscopic ultrasound (EUS) with/without fine needle aspiration cytology (FNAC) and were followed clinically, biochemically with/without radiology for up to six months. The findings of EUS were corroborated with histopathology of surgical specimens and endoscopic retrograde cholangiography (ERCP) findings in relevant cases. RESULTS: Median age of 121 patients completing follow up was 55 years. 98.2% patients were symptomatic and median common bile duct (CBD) diameter was 13 mm. EUS was able to identify lesions attributable for biliary dilatation in (67 out of 121) 55.4% cases with ampullary neoplasm being the commonest (29 out of 67 i.e. 43%). Multivariate logistic regression analysis identified jaundice as the predictor of positive diagnosis on EUS, of finding ampullary lesion and pancreatic lesion on EUS. EUS had sensitivity, specificity, positive predictive value and diagnostic accuracy of 95.65%, 94.23%, 95.65% and 95.04% respectively in providing etiologic diagnosis. Threshold value for baseline bilirubin of 10 mg%, for baseline CA 19.9 of 225 u/L and for largest CBD diameter of 16 mm were determined to have specificity of 98%, 95%, 92.5% respectively of finding a positive diagnosis on EUS. CONCLUSION: EUS provides considerable diagnostic yield with high accuracy in biliary dilatation when cross sectional imaging fails to provide etiologic diagnosis.

ABSTRACT

BACKGROUND: Amantadine hydrochloride has been increasingly prescribed as a neurostimulant for neurocritical care stroke patients to promote wakefulness during inpatient recovery. However, a lack of guidelines makes it difficult to decide who may benefit from this pharmacotherapy and when amantadine should be initiated during the hospital stay. This study aims to determine some factors that may be associated with favorable response to amantadine to inform future randomized controlled trials of amantadine in critical care or post-critical care stroke patients. METHODS: Retrospective chart review for this study included neurocritical care and post-neurocritical care patients with acute ischemic or hemorrhagic stroke who were started on amantadine (N = 34) in the years 2016-2019. Patients were labeled as either responders or nonresponders of amantadine within 9 days of initiation using novel amantadine scoring criteria utilized and published in Neurocritical Care in the year 2021, which included spontaneous wakefulness and Glasgow Coma Scale (GCS). Amantadine response status and predictive variables were analyzed using nonparametric tests and adjusted multivariable regression models. RESULTS: There were large but nonsignificant variations in the median total milligrams of amantadine received in the first 9 days (IQR = 700-1,450 mg, p = 0.727). GCS on the day before amantadine initiation was significantly higher for responders (median = 12, IQR = 9-14) than nonresponders (median = 9, IQR = 8-10, p = 0.009). Favorable responder status was significantly associated with initiation in the critical care unit versus the step-down unit or the general medical/surgical floor [𝛃=1.02, 95% CI (0.10, 1.93), p = 0.031], but there was no significant associations with hospital day number started [𝛃=-0.003, 95% CI (-0.02, 0.02), p = 0.772]. CONCLUSIONS: Future randomized controlled trials of amantadine in hospitalized stroke patients should possibly consider examining dose-dependent relationships to establish stroke-specific dosing guidelines, minimum GCS threshold for which amantadine is efficacious, and the impact of patients' determined level of acuity on clinical outcomes instead of solely examining the impact of earlier amantadine initiation by hospital day number. Future research with larger sample sizes is needed to further examine these relationships and inform future clinical trials.

ABSTRACT

Multispecies studies are known for tackling human exceptionalism. Whilst the field has seen a remarkable increase in popularity amongst scholars in the humanities and social sciences, critiques argue that it neglects inequalities and consequential differences amongst humans and between humans and other-than-humans. These critiques are especially relevant in the context of Southern Africa, where extreme inequalities amongst humans persist whilst wildlife is often perceived to enjoy a favoured position in the region's prominent conservation industries. As four researchers working in a multispecies study project focusing on the Kavango-Zambezi Transfrontier Conservation Area in Southern Africa, we pose the question of what a politicised multispecies studies might look like. In this article, we share our thoughts and reflections on working in this complex political landscape. Using insights from our own fields, we share some of the persistent concerns encountered during fieldwork and discuss and contextualise these by drawing on multispecies literature that deals with similar concerns. We identify three salient themes that should inform and politicise multispecies work in postcolonial conservation landscapes: historical legacies, reflexive positionalities and marginalised subjects.


Os estudos multiespécies são conhecidos por enfrentar a questão do excepcionalismo humano. Embora o campo tenha registrado um aumento notável em popularidade entre os estudiosos das ciências humanas e sociais, os críticos argumentam que ele negligencia as desigualdades e as consequentes diferenças entre os humanos e entre humanos e não humanos. Estas críticas são especialmente relevantes no contexto da África Austral, onde desigualdades extremas entre os seres humanos persistem, enquanto a vida selvagem é frequentemente entendida como tendo uma posição privilegiada nas proeminentes indústrias de conservação da região. Como quatro investigadores que trabalham em um projeto de estudo multiespécies com foco na Área deConservação Transfronteiriça Cubango-Zambeze, na África Austral, colocamos a questão de como seria um estudo multiespécies politizado. Neste artigo, compartilhamos nossas ideias e reflexões sobre o trabalho neste cenário político complexo. Utilizando observações oriundas de nossas próprias pesquisas, partilhamos algumas das persistentes inquietações encontradas durante o trabalho de campo, bem como discutimos e contextualizamos estas questões recorrendo à literatura multiespécies que trata de preocupações semelhantes. Identificamos três temas de relevo que devem informar e politizar o trabalho multiespécies em cenários pós-coloniais de conservação: os legados históricos, as posicionalidades reflexivas e os sujeitos marginalizados.

ABSTRACT

Lyme disease, a tick-borne illness, is caused by the spirochete Borrelia burgdorferi. Lyme disease commonly presents with the characteristic erythema migrans rash, fever, malaise, headache, and arthralgias. Some patients may have mild liver manifestations, including abnormal liver function tests (LFTs), hyperbilirubinemia, or granulomatous hepatitis. Significant LFT abnormalities and hepatitis in a case of Lyme disease are rare. Here, we present a case of Lyme hepatitis in the emergency department (ED) where the patient presented with classic Lyme symptoms and was also found to have markedly elevated aspartate transaminase (AST) and alanine transaminase (ALT), mild alkaline phosphatase (ALP) elevation, and mild hyperbilirubinemia.
