RESUMEN
We analyzed West Nile Virus (WNV) exposure from 1,222 blood donors during 2017-2018 from an area of south-central Spain. Results revealed WNV seroprevalence of 0.08% (95% CI 0.004%-0.4%) in this population. Our findings underscore the need for continued surveillance and research to manage WNV infection in this region.

We conducted a cross-sectional study in wild boar and extensively managed Iberian pig populations in a hotspot area of Crimean-Congo hemorrhagic fever virus (CCHFV) in Spain. We tested for antibodies against CCHFV by using 2 ELISAs in parallel. We assessed the presence of CCHFV RNA by means of reverse transcription quantitative PCR protocol, which detects all genotypes. A total of 113 (21.8%) of 518 suids sampled showed antibodies against CCHFV by ELISA. By species, 106 (39.7%) of 267 wild boars and 7 (2.8%) of 251 Iberian pigs analyzed were seropositive. Of the 231 Iberian pigs and 231 wild boars analyzed, none tested positive for CCHFV RNA. These findings indicate high CCHFV exposure in wild boar populations in endemic areas and confirm the susceptibility of extensively reared pigs to CCHFV, even though they may only play a limited role in the enzootic cycle.

We identified rat hepatitis E virus (HEV) RNA in farmed pigs from Spain. Our results indicate that pigs might be susceptible to rat HEV and could serve as viral intermediaries between rodents and humans. Europe should evaluate the prevalence of rat HEV in farmed pigs to assess the risk to public health.

Patients with Down syndrome have significant specialized health care needs. Our objective was to understand the needs, satisfaction, and online habits of caregivers as they care for persons with Down syndrome. A mixed-method survey was distributed through REDCap from April 2022 to June 2022 in the United States; a Spanish-translated version was distributed through SurveyMonkey from August 2022 to March 2023 in Mexico. We received 290 completed responses from the United States and 58 from caregivers in Mexico. We found that current health care options are not meeting the needs of many individuals with DS in both the United States (39.7%) and Mexico (46.6%). Caregivers expressed frustrations with the inaccessibility and inapplicability of health care information. In particular, they often found the volume of information overwhelming, given their limited medical background. Additionally, health care recommendations were not customized and lacked practical recommendations. Most caregivers in both the United States (72.1%) and Mexico (82.8%) believe it is not easy to find answers to medical questions about their loved ones with DS. Online platforms with customized, specific health information related to DS could offer innovative solutions to these unmet needs for families and primary care providers.

SUMMARY: The analysis of stable isotope labeling experiments requires accurate, efficient, and reproducible quantification of mass isotopomer distributions (MIDs), which is not a core feature of general-purpose metabolomics software tools that are optimized to quantify metabolite abundance. Here, we present PIRAMID (Program for Integration and Rapid Analysis of Mass Isotopomer Distributions), a MATLAB-based tool that addresses this need by offering a user-friendly, graphical user interface-driven program to automate the extraction of isotopic information from mass spectrometry (MS) datasets. This tool can simultaneously extract ion chromatograms for various metabolites from multiple data files in common vendor-agnostic file formats, locate chromatographic peaks based on a targeted list of characteristic ions and retention times, and integrate MIDs for each target ion. These MIDs can be corrected for natural isotopic background based on the user-defined molecular formula of each ion. PIRAMID offers support for datasets acquired from low- or high-resolution MS, and single (MS) or tandem (MS/MS) instruments. It also enables the analysis of single or dual labeling experiments using a variety of isotopes (i.e. 2H, 13C, 15N, 18O, 34S). DATA AVAILABILITY AND IMPLEMENTATION: MATLAB p-code files are freely available for non-commercial use and can be downloaded from https://mfa.vueinnovations.com/. Commercial licenses are also available. All the data presented in this publication are available under the "Help_menu" folder of the PIRAMID software.

Two of 11 children with acute hepatitis of unknown origin were found to have rat hepatitis E virus infection. This infection should be considered in the differential diagnosis of children with acute hepatitis of unknown origin.
RESUMEN
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), considered a zoonotic agent of wildlife origin, can infect various animal species, including wildlife in free-range and captive environments. Detecting susceptible species and potential reservoirs is crucial for preventing the transmission, spread, genetic evolution, and further emergence of viral variants that are major threats to global health. This study aimed to detect exposure or acute infection by SARS-CoV-2 in 420 animals from 40 different wildlife species, including terrestrial and aquatic mammals, from different regions of Spain during the 2020-2023 coronavirus disease 19 (COVID-19) pandemic. In total, 8/137 animals were positive for SARS-CoV-2 antibodies against the receptor binding domain and/or viral nucleoprotein according to independent ELISAs. However, only one ELISA-positive sample of a captive bottlenose dolphin (Tursiops truncatus) tested positive for SARS-CoV-2 neutralizing antibodies with a low titre (SNT50 38.15) according to a virus neutralization test. Cetaceans are expected to have a high risk of infection with SARS-CoV-2 according to early predictive studies due to the similarity of their angiotensin converting enzyme 2 cell receptor to that of humans. Moreover, of 283 animals analysed for SARS-CoV-2 RNA using RT-qPCR, none tested positive. Our results reinforce the importance of considering cetaceans at risk for SARS-CoV-2 infection and support taking preventive biosecurity measures when interacting with them, especially in the presence of individuals with suspected or confirmed COVID-19. Although most animals in this study tested negative for acute infection or viral exposure, ongoing surveillance of wildlife species and potentially susceptible animals is important to prevent future spillover events and detect potential novel reservoirs.

Microsporidia is a diverse group of obligate, intracellular, and spore-forming parasites that infect a wide range of animals. Among them, Enterocytozoon bieneusi and Encephalitozoon spp. are the most frequently reported species in humans. Limited information is available about the presence and molecular diversity of microsporidian species in the endangered Iberian lynx (Lynx pardinus). Presence of Enterocytozoon bieneusi and Encephalitozoon spp. was investigated by molecular methods in wild and captive Iberian lynxes from Spain. Overall, E. bieneusi was detected in 3.2% (8/251) of the animals examined. None of the samples tested were positive for Encephalitozoon spp. Four known (D, EbfelA, PigEBITS7, and Type IV) and a novel (named as LynxSpEb1) E. bieneusi genotypes were identified. All the genotypes found belonged to the zoonotic Group 1 of E. bieneusi. This study provides the first genotyping data of E. bieneusi in Iberian lynx in Spain. Our result indicate that the Iberian lynx does not seem to play a relevant role in the epidemiology of Encephalitozoon spp., and that this endangered felid is likely acting as spillover host rather than a true reservoir of E. bieneusi. Additional studies should be conducted to assess the impact of this parasite in the health status of the endangered Iberian lynx.

The Anthrax mailings bioterrorism attack in 2001 revealed the need for universal and rapid microbial forensic analyses on unknown biological evidence. However, the gold standard for bacterial identification includes culturing isolates, which is laborious. Molecular approaches for bacterial identification revolve around 16S ribosomal gene sequencing using Sanger or next generation sequencing (NGS) platforms, but these techniques are laboratory-based and can also be time-consuming. The Oxford Nanopore Technologies (ONT) MinION sequencer can generate long read lengths that span the entire bacterial 16S rRNA gene and accurately identify the species level. This platform can be used in the field, allowing on-site evidence analysis. However, it requires higher quantities of pure DNA compared to other sequencing platforms; thus, the extraction method for bacterial DNA is critical for downstream analysis, which to date are tailored toward a priori knowledge of the species' taxonomic grouping. During an attack, the investigative team may not know what species they are handling; therefore, identifying an extraction method that can handle all bacterial groups and generate clean DNA for the MinION is useful for microbial forensic analysis. The purpose of this study was to identify a "universal" extraction method that can be coupled with ONT MinION sequencing for use in forensic situations for rapid identification. It also evaluated the cloud-based data analysis software provided by ONT, EPI2ME. No "universal" extraction method was identified as optimal for downstream MinION sequencing. However, the DNeasy PowerSoil Kit and Noda et al. Chelex-100 method gave comparable sequencing results and could be used as rapid extraction techniques. This study showed that the ONT 16S Barcoding Kit 1-24 coupled with the 16S FASTQ workflow might not be the best for use in forensic situations where species-level identification needs to be obtained, as most alignments were approximately 89% accurate. In all seven test organisms and nine extraction methods, accurate species identification was only obtained in 63% of the cases.

AIM: Venous thromboembolic events (VTEs) are relatively common adverse surgical complications. Extended VTE prophylaxis for 4 weeks is recommended after colorectal cancer surgery, but its use in inflammatory bowel disease surgery lacks high-quality evidence. This retrospective study aimed to assess and characterize VTEs within the first 30 days after ileal pouch-anal anastomosis (IPAA) procedures and subtotal colectomies (STCs) for ulcerative colitis (UC). METHODS: All patients who underwent IPAA for UC between 1 January 2017 and 31 December 2021 were included. VTE rates after IPAA, in-hospital or at-home occurrences, utilization of in-hospital thromboprophylaxis, and prescribed anticoagulant treatment were evaluated. Retrospectively, the same variables were analysed if patients of the cohort underwent STC before the IPAA construction. RESULTS: In all, 204 patients underwent IPAA (61.8% men, 73% laparoscopic), with an average hospital stay of 6.8 days. Among them, 116 patients underwent STC prior to IPAA. Thirteen patients (6.3%) experienced VTEs after IPAA, with 76.9% (10/13) of cases occurring during hospitalization and under adequate thromboprophylaxis. The VTE rate after STC was 10.3% (12/116), with 58.2% (7/12) occurring in hospital and under appropriate thromboprophylaxis. No reoperations or mortality were attributed to thrombotic events. The type and duration of anticoagulant treatment varied considerably. CONCLUSION: The VTE rate after IPAA for UC was 6.3%, with the majority of events occurring in hospital and under adequate thromboprophylaxis. These findings suggest that routine use of extended VTE prophylaxis in our cohort may not be supported. Further research is needed to clarify the optimal VTE prophylaxis strategy for inflammatory bowel disease surgery.

AIM: Recent evidence challenges the current standard of offering surgery to patients with ileocaecal Crohn's disease (CD) only when they present complications of the disease. The aim of this study was to compare short-term results of patients who underwent primary ileocaecal resection for either inflammatory (luminal disease, earlier in the disease course) or complicated phenotypes, hypothesizing that the latter would be associated with worse postoperative outcomes. METHOD: A retrospective, multicentre comparative analysis was performed including patients operated on for primary ileocaecal CD at 12 referral centres. Patients were divided into two groups according to indication of surgery for inflammatory (ICD) or complicated (CCD) phenotype. Short-term results were compared. RESULTS: A total of 2013 patients were included, with 291 (14.5%) in the ICD group. No differences were found between the groups in time from diagnosis to surgery. CCD patients had higher rates of low body mass index, anaemia (40.9% vs. 27%, p < 0.001) and low albumin (11.3% vs. 2.6%, p < 0.001). CCD patients had longer operations, lower rates of laparoscopic approach (84.3% vs. 93.1%, p = 0.001) and higher conversion rates (9.3% vs. 1.9%, p < 0.001). CCD patients had a longer hospital stay and higher postoperative complication rates (26.1% vs. 21.3%, p = 0.083). Anastomotic leakage and reoperations were also more frequent in this group. More patients in the CCD group required an extended bowel resection (14.1% vs. 8.3%, p: 0.017). In multivariate analysis, CCD was associated with prolonged surgery (OR 3.44, p = 0.001) and the requirement for multiple intraoperative procedures (OR 8.39, p = 0.030). CONCLUSION: Indication for surgery in patients who present with an inflammatory phenotype of CD was associated with better outcomes compared with patients operated on for complications of the disease. There was no difference between groups in time from diagnosis to surgery.

BACKGROUND: Down syndrome (DS) is the most prevalent chromosomal disorder, being the leading cause of intellectual disability. The increased life expectancy of individuals with DS has led to a shift in the incidence of non-communicable chronic diseases, resulting in new concerns, particularly cardiovascular disease (CVD) and Alzheimer's disease. This study aimed to analyse the blood lipid profile of a large DS cohort to establish a baseline for evaluating health risk parameters. METHODS: A comprehensive literature search was conducted on PubMed and Virtual Health Library databases to identify original articles published before July 2022. Selected studies were included in the meta-analysis. RESULTS: Fifteen studies reporting serum lipid levels in individuals with DS were incorporated into the analysis. The meta-analysis used the means and standard deviations extracted from the selected studies. The analysis encompassed 671 participants in the DS group and 898 euploid controls. The results indicated significant differences in total cholesterol [C] (mean difference [MD]: -3.34; CI: 95%: -4.94 to -1.73; P < 0.0001), HDL-C (MD: -3.39; CI: 95%: -6.72 to -0.06; P = 0.05) and triglycerides (MD: 21.48; CI: 95%: 9.32 to 33.65; P = 0.0005) levels between individuals with DS and their control counterparts. CONCLUSIONS: Individuals with DS have less favourable blood lipid concentrations than their controls, particularly HDL-C, triglycerides, and total-C, even when grouped by age. These findings underscore the importance of closer monitoring of lipid profiles in people with DS and the necessity for specific cut-offs for this population, considering the risk for ischemic heart and Alzheimer's diseases.

The coronavirus disease (COVID-19) pandemic, caused by SARS-CoV-2 coronavirus, is devastatingly impacting human health. A prominent component of COVID-19 is the infection and destruction of the ciliated respiratory cells, which perpetuates dissemination and disrupts protective mucociliary transport (MCT) function, an innate defense of the respiratory tract. Thus, drugs that augment MCT could improve the barrier function of the airway epithelium and reduce viral replication and, ultimately, COVID-19 outcomes. We tested five agents known to increase MCT through distinct mechanisms for activity against SARS-CoV-2 infection using a model of human respiratory epithelial cells terminally differentiated in an air/liquid interphase. Three of the five mucoactive compounds tested showed significant inhibitory activity against SARS-CoV-2 replication. An archetype mucoactive agent, ARINA-1, blocked viral replication and therefore epithelial cell injury; thus, it was further studied using biochemical, genetic, and biophysical methods to ascertain the mechanism of action via the improvement of MCT. ARINA-1 antiviral activity was dependent on enhancing the MCT cellular response, since terminal differentiation, intact ciliary expression, and motion were required for ARINA-1-mediated anti-SARS-CoV2 protection. Ultimately, we showed that the improvement of cilia movement was caused by ARINA-1-mediated regulation of the redox state of the intracellular environment, which benefited MCT. Our study indicates that intact MCT reduces SARS-CoV-2 infection, and its pharmacologic activation may be effective as an anti-COVID-19 treatment.

As compared to eukaryotes, bacteria have a reduced tRNA gene set encoding between 30 and 220 tRNAs. Although in most bacterial phyla tRNA genes are dispersed in the genome, many species from distinct phyla also show genes forming arrays. Here, we show that two types of arrays with distinct evolutionary origins exist. This work focuses on long tRNA gene arrays (L-arrays) that encompass up to 43 genes, which disseminate by horizontal gene transfer and contribute supernumerary tRNA genes to the host. Although in the few cases previously studied these arrays were reported to be poorly transcribed, here we show that the L-array of the model cyanobacterium Anabaena sp. PCC 7120, encoding 23 functional tRNAs, is largely induced upon impairment of the translation machinery. The cellular response to this challenge involves a global reprogramming of the transcriptome in two phases. tRNAs encoded in the array are induced in the second phase of the response, directly contributing to cell survival. Results presented here show that in some bacteria the tRNA gene set may be partitioned between a housekeeping subset, which constantly sustains translation, and an inducible subset that is generally silent but can provide functionality under particular conditions.

The intricate mechanisms governing brain health and function have long been subjects of extensive investigation. Recent research has shed light on two pivotal systems, the glymphatic system and the endocannabinoid system, and their profound role within the central nervous system. The glymphatic system is a recently discovered waste clearance system within the brain that facilitates the efficient removal of toxic waste products and metabolites from the central nervous system. It relies on the unique properties of the brain's extracellular space and is primarily driven by cerebrospinal fluid and glial cells. Conversely, the endocannabinoid system, a multifaceted signaling network, is intricately involved in diverse physiological processes and has been associated with modulating synaptic plasticity, nociception, affective states, appetite regulation, and immune responses. This scientific review delves into the intricate interconnections between these two systems, exploring their combined influence on brain health and disease. By elucidating the synergistic effects of glymphatic function and endocannabinoid signaling, this review aims to deepen our understanding of their implications for neurological disorders, immune responses, and cognitive well-being.

The oxylipin-dependent quorum-sensing system (ODS) of Pseudomonas aeruginosa relies on the production and sensing of two extracellular oxylipins, 10S-hydroxy-(8E)-octadecenoic acid (10-HOME) and 7S,10S-dihydroxy-(8E)-octadecenoic acid (7,10-DiHOME). Here, we implemented a genetic screen of P. aeruginosa strain PAO1 aimed to identify genes required for 10-HOME and 7,10-DiHOME production. Among the 14 genes identified, four encoded previously known components of the ODS and 10 encoded parts of the Xcp type II secretion system (T2SS). We subsequently created a clean xcpQ deletion mutant, which encodes the necessary outer membrane component of Xcp, and found it recapitulated the impaired functionality of the T2SS transposon mutants. Further studies showed that the ΔxcpQ mutant was unable to secrete the oxylipin synthase enzymes across the outer membrane. Specifically, immunoblotting for OdsA, which is responsible for the generation of 10-HOME from oleic acid, detected the enzyme in supernatants from wild-type PAO1 but not ΔxcpQ cultures. Likewise, chromatography of supernatants found that 10-HOME was not in supernatants collected from the ΔxcpQ mutant. Accordingly, diol synthase activity was increased in the periplasm of ΔxcpQ mutant consistent with a stoppage in its transport. Importantly, after exposure of the ΔxcpQ mutant to exogenous 10-HOME and 7,10-DiHOME, the ODS effector genes become active; thus, the sensing component of the ODS does not involve the T2SS. Finally, we observed that Xcp contributed to robust in vitro and in vivo biofilm formation in oleic acid availability- and ODS-dependent manner. Thus, T2SS-mediated transport of the oxylipin synthase enzymes to outside the bacterial cell is required for ODS functionality. IMPORTANCE We previously showed that the ODS of P. aeruginosa produces and responds to oxylipins derived from host oleic acid by enhancing biofilm formation and virulence. Here, we developed a genetic screen strategy to explore the molecular basis for oxylipins synthesis and detection. Unexpectedly, we found that the ODS autoinducer synthases cross the outer membrane using the Xcp type 2 secretion system (T2SS) of P. aeruginosa, and so the biosynthesis of oxylipins occurs extracellularly. T2SS promoted biofilm formation in the presence of oleic acid as a result of ODS activation. Our results identify two new T2SS secreted proteins in P. aeruginosa and reveal a new way by which this important opportunistic pathogen interacts with the host environment.

MOTIVATION: Since its launch in 2010, Identifiers.org has become an important tool for the annotation and cross-referencing of Life Science data. In 2016, we established the Compact Identifier (CID) scheme (prefix: accession) to generate globally unique identifiers for data resources using their locally assigned accession identifiers. Since then, we have developed and improved services to support the growing need to create, reference and resolve CIDs, in systems ranging from human readable text to cloud-based e-infrastructures, by providing high availability and low-latency cloud-based services, backed by a high-quality, manually curated resource. RESULTS: We describe a set of services that can be used to construct and resolve CIDs in Life Sciences and beyond. We have developed a new front end for accessing the Identifiers.org registry data and APIs to simplify integration of Identifiers.org CID services with third-party applications. We have also deployed the new Identifiers.org infrastructure in a commercial cloud environment, bringing our services closer to the data. AVAILABILITYAND IMPLEMENTATION: https://identifiers.org.

Establishing an accurate diagnosis of amyloid subtype in patients with coexistent cardiac amyloidosis and monoclonal gammopathy is crucial due to treatment and prognostic implications. Here, we discuss a case of coexistent diagnoses of transthyretin amyloid cardiomyopathy and smoldering multiple myeloma, highlighting the challenges associated with the possibility of several disease combinations and the limitations of diagnostic testing. In addition, the importance of clinical clues such as disease course and progression, patient preference, and multidisciplinary collaboration should not be discounted in the diagnostic and management approach of these patients.

OBJECTIVE: To investigate the effectiveness of thermal and sub-thermal capacitive-resistive monopolar radiofrequency at 448â kHz plus exercising compared to sham radiofrequency plus exercising on pain, functionality, and quality of life in patients with subacromial pain. DESIGN: Randomized, controlled, parallel, double-blind, three-arm clinical trial. SETTING: Hospital and Primary Care. SUBJECTS: Eighty-one participants with subacromial pain in three intervention groups. INTERVENTIONS: Three interventions with capacitive-resistive radiofrequency (thermal, sub-thermal, and sham) over 9 sessions (3 per week) plus an exercising protocol identical for all groups over 15 sessions (5 per week). OUTCOME MEASURES: Visual analogue scale and pressure pain threshold for pain, Shoulder Pain and Disability Index and Quick-Disabilities of the Arm, Shoulder and Hand for functionality, and quality of life via the European Quality of Life-Five Dimensions were assessed at baseline, immediately posttreatment, and 1 month and 3 months post-intervention. RESULTS: No between-group differences were found in the pain visual analogue scale (F = 1.0; P = 0.37), Shoulder Pain and Disability Index (F = 1.0; P = 0.36), European Quality of Life-Five Dimensions (F = 0.76; P = 0.47), and pressure pain (F = 0.14; P = 0.86) outcomes, with a statistical power < 0.30 for all comparisons. Between-group differences were found in the Quick-Disabilities of the Arm, Shoulder and Hand (F = 3.4; P < 0.038), with an improvement of -14.1 points (confidence interval at 95% (95% CI) -28.1 to -0.1) in the thermal versus the sham group at 1 month follow-up. The mobility dimension of European Quality of Life-Five Dimensions improved in a greater proportion of participants in the thermal group (22.2% thermal, 7.4% sub-thermal, and 0.0% sham; P = 0.02). CONCLUSION: Adding thermal radiofrequency to exercising can further improve slightly functionality and mobility in people with subacromial pain in the short term, but not pain perception. Future studies with larger sample sizes are warranted to increase statistical power.
