RESUMEN

Transcatheter aortic valve implantation (TAVI) is the alternative to surgical valve replacement, expanding its indications in the latest guidelines. Multimodal CT (MDCT) is essential in patient selection and detection of complications. Vascular complications are frequent, so it is important to analyse the anatomy of the vessels before the procedure. Regarding annular ruptures and ventricular perforations, the volume and distribution of calcium and the ventricular diameter play an important role. Finally, valve migration is a rare complication that can occur both during and after TAVI. Proper planning of the MDCT procedure reduces the risk of complications and gives the interventional cardiologist security both before and during the procedure.

RESUMEN

Papillary endothelial hyperplasia (PEH) or Masson's tumor is a rare benign vascular tumor that usually appears in the soft tissues of the head and neck, trunk and extremities, being extremely rare in the breast. Its diagnosis can be a challenge, especially in the follow-up of patients with previous disease of breast carcinoma. We present the case of a 65-year-old patient, with a history of bilateral breast cancer and reconstruction with implants, who presented a Masson's tumor during follow-up. An ultrasound scan was performed, showing a well-circumscribed mass in the left breast, located in the posterior contour of the implant. Subsequently, magnetic resonance imaging (MR) depicted an enhancing tumor, without infiltration of adjacent structures. Finally, the definitive anatomopathological diagnosis was obtained after surgical excision.

RESUMEN

We present a flora and fauna dataset for the Mira-Mataje binational basins. This is an area shared between southwestern Colombia and northwestern Ecuador, where both the Chocó and Tropical Andes biodiversity hotspots converge. We systematized data from 120 sources in the Darwin Core Archive (DwC-A) standard and geospatial vector data format for geographic information systems (GIS) (shapefiles). Sources included natural history museums, published literature, and citizen science repositories across 13 countries. The resulting database has 33,460 records from 6,821 species, of which 540 have been recorded as endemic, and 612 as threatened. The diversity represented in the dataset is equivalent to 10% of the total plant species and 26% of the total terrestrial vertebrate species in both hotspots. The dataset can be used to estimate and compare biodiversity patterns with environmental parameters and provide value to ecosystems, ecoregions, and protected areas. The dataset is a baseline for future assessments of biodiversity in the face of environmental degradation, climate change, and accelerated extinction processes.

RESUMEN

PREMISE: Increasingly complete phylogenies underpin studies in systematics, ecology, and evolution. Myrteae (Myrtaceae), with ~2700 species, is a key component of the exceptionally diverse Neotropical flora, but given its complicated taxonomy, automated assembling of molecular supermatrices from public databases often lead to unreliable topologies due to poor species identification. METHODS: Here, we build a taxonomically verified molecular supermatrix of Neotropical Myrteae by assembling 3909 published and 1004 unpublished sequences from two nuclear and seven plastid molecular markers. We infer a time-calibrated phylogenetic tree that covers 712 species of Myrteae (~28% of the total diversity in the clade) and evaluate geographic and taxonomic gaps in sampling. RESULTS: The tree inferred from the fully concatenated matrix mostly reflects the topology of the plastid data set and there is a moderate to strong incongruence between trees inferred from nuclear and plastid partitions. Large, species-rich genera are still the poorest sampled within the group. Eastern South America is the best-represented area in proportion to its species diversity, while Western Amazon, Mesoamerica, and the Caribbean are the least represented. CONCLUSIONS: We provide a time-calibrated tree that can be more reliably used to address finer-scale eco-evolutionary questions that involve this group in the Neotropics. Gaps to be filled by future studies include improving representation of taxa and areas that remain poorly sampled, investigating causes of conflict between nuclear and plastid partitions, and the role of hybridization and incomplete lineage sorting in relationships that are poorly supported.

RESUMEN

INTRODUCTION: The treatment and diagnosis of chronic diarrhea in the immunocompromised patient depends on the ability to rapidly detect the etiologic agents. AIMS: Our aim was to evaluate the results of the FilmArray® gastrointestinal panel in patients newly diagnosed with HIV infection that presented with chronic diarrhea. MATERIAL AND METHODS: Utilizing nonprobability consecutive convenience sampling, 24 patients were included that underwent molecular testing for the simultaneous detection of 22 pathogens. RESULTS: In 24 HIV-infected patients with chronic diarrhea, enteropathogen bacteria were detected in 69% of the cases, parasites in 18%, and viruses in 13%. Enteropathogenic Escherichia coli and enteroaggregative Escherichia coli were the main bacteria identified, Giardia lamblia was found in 25%, and norovirus was the most frequent viral agent. The median number of infectious agents per patient was three (range of 0 to 7). The biologic agents not identified through the FilmArray® method were tuberculosis and fungi. CONCLUSIONS: Several infectious agents were simultaneously detected through the FilmArray® gastrointestinal panel in patients with HIV infection and chronic diarrhea.

RESUMEN

OBJECTIVES: This study aimed to analyze the effects of the COVID-19 pandemic on non-COVID-19 healthcare utilization in Mexico, including oral health, mental health, communicable disease visits, health checkups, chronic degenerative disease visits, postpartum care, prenatal care, and family planning visits. STUDY DESIGN: This was a retrospective ecological analysis during the COVID-19 pandemic. During the pandemic, the Mexican government recommended non-essential consultations be suspended or rescheduled to accommodate the new demand for healthcare services from COVID-19 patients. METHODS: This study uses administrative data from Mexico's Ministry of Health from January 2017 to December 2022. These data cover 14,299 consultation units and 775 hospitals from the 32 Mexican States, all of which are public institutions. A difference-in-differences strategy and an event study specification are used to study the impacts of the pandemic on non-COVID-19 healthcare utilization. RESULTS: The findings reveal a decrease in the utilization of all healthcare services: oral health (69%), mental health (27%), communicable diseases (46%), chronic degenerative diseases (36%), health checkups (62%), family planning (45%), prenatal care (36%), and postpartum care (44%). Furthermore, the event study indicates that most services follow a U-shaped trend, although only mental health services clearly return to prepandemic levels. The remainder of services remain below prepandemic levels at the end of 2022. CONCLUSIONS: The 2020 pandemic had detrimental effects on non-COVID-19 healthcare utilization. The healthcare interruptions will likely impact short- and long-term morbidity and mortality. Programs intended to remediate these negative consequences may be of interest to public health policymakers.

RESUMEN

Antibody biotinylation is a process of attaching biotin molecules to antibodies by chemically modifying specific functional groups on the antibodies without altering their antigen recognition specificity. Biotin, a small vitamin, forms a strong and specific interaction with the protein streptavidin, resulting in a stable biotin-streptavidin (biotin-STV) complex. This biotin-STV interaction is widely exploited in various biotechnological applications, including biosensors. Biosensors are analytical devices that employ biological recognition elements, such as antibodies, enzymes, or nucleic acids, to detect and quantify target analytes in a sample. Antibodies are commonly used as recognition elements in biosensors due to their high specificity and affinity. In this study, the antibody anti-Bovine Serum Albumin (αBSA) has been biotinylated at different antibody:biotin ratios, and the stability of this labeling over time has been investigated. Furthermore, the sensitivity of the biosensor for detecting the Bovine Serum Albumin (BSA) protein has been compared using the biotinylated antibody and the non-biotinylated form, showing a four-fold improvement in detection. This system was also compared with the Enzyme-Linked ImmunoSorbent Assay (ELISA) technique. The advantages of using biotinylated antibodies in biosensors include increased stability and reproducibility of the biorecognition layer, as well as flexibility in sensor design, as different biotinylated antibodies can be utilized for diverse target analytes without altering the sensor's architecture.

RESUMEN

Case: A previously healthy 11-year-old girl underwent expedited surgical fixation of a femoral neck fracture sustained while jump-roping. After further work up, she was diagnosed with primary hyperparathyroidism. Parathyroidectomy of a hypertrophic adenoma proved curative. Now, five months post left hip surgery, the patient is pain-free and walks without a limp. Conclusion: We describe the first published case of primary hyperparathyroidism presenting as a pathologic hip fracture in a child. Although presentation with a fracture is exceedingly rare, bone pain is a frequent complaint of pediatric hyperparathyroidism. Orthopedic surgeons may find themselves the front-line caregivers for the condition.

RESUMEN

La anomalía linfática generalizada (ALG) es una enfermedad congénita poco frecuente, secundaria a la proliferación de vasos linfáticos en cualquier órgano a excepción del sistema nervioso central, mostrando un amplio abanico de formas de presentación clínicas y radiológicas. Las lesiones osteolíticas son una constante, y las costillas, el hueso más frecuentemente afectado. Se diagnostica principalmente en niños y adultos jóvenes; no obstante, en raras ocasiones la enfermedad puede ser asintomática y detectarse de forma incidental en pacientes de mayor edad. Presentamos un caso inusual de ALG en un paciente de 54 años, asintomático y con presencia de lesiones óseas de distribución atípica en la tomografía computarizada (TC). La naturaleza puramente quística de las lesiones, evidenciada mediante la medición de las unidades Hounsfield, permitió establecer el diagnóstico de sospecha de ALG, que posteriormente se confirmó con resonancia magnética, tomografía por emisión de positrones/TC, punción aspiración con aguja fina guiada por TC y biopsia vertebral percutánea con guía fluoroscópica. Finalmente, se obtuvo el diagnóstico anatomopatológico definitivo tras la resección quirúrgica de una de las lesiones.(AU)


Generalized lymphatic anomaly (GLA) is an uncommon congenital disease secondary to the proliferation of lymphatic vessels in any organ except the central nervous system. GLA has a wide spectrum of clinical and radiological presentations, among which osteolytic lesions are the most widespread, being the ribs the most commonly affected bone. GLA is diagnosed mainly in children and young adults; nevertheless, on rare occasions it can remain asymptomatic and be detected incidentally in older patients. We present an unusual case of GLA in an asymptomatic 54-year-old man who had atypically distributed, purely cystic bone lesions on CT; measuring the Hounsfield (HU) of these lesions enabled us to suspect GLA. This suspicion was confirmed with MRI, PET/CT, CT-guided fine-needle aspiration biopsy, and fluoroscopy-guided percutaneous vertebral biopsy. After surgical resection of one of the lesions, histologic study provided the definitive diagnosis.(AU)

RESUMEN

Lentinus crinitus (L.) Fr is a wild macrofungus that is popular as antimicrobial and various biological activities. This study aims to determine the capacity growth stimulation of Lactobacillus paracasei and antimicrobial activity of aqueous extracts of L. crinitus obtained from wild basidiomata, mycelial biomass by liquid fermentation and spent mushroom substrate obtained by solid-state fermentation. The antimicrobial activity was investigated against bacterial and fungal pathogens and growth stimulation L. paracasei probiotic bacterium. The total carbohydrate and ß-glucan contents of the extracts were determined using colorimetric analysis. The aqueous extracts obtained showed inhibition against Fusarium oxysporum., Penicillium sp., Rhizopus oryzae, Aspergillus niger, Escherichia coli and Salmonella typhimurium. The aqueous extract obtained from wild basidiomata, and mycelial biomass showed the highest percentage of stimulation of L. paracasei growth in 48 h. The extracts obtained from L. crinitus have antimicrobial potential and stimulating capacity of the probiotic Lactobacillus paracasei. Additionally, different biotechnological techniques such as liquid and solid-state fermentation can be used to obtain aqueous extracts.

RESUMEN

INTRODUCTION: New-onset super-refractory status epilepticus (NOSRSE) is a neurological emergency characterised by the development of status epilepticus in a patient without epilepsy or any known prior neurological disease and with no clear structural, toxic or metabolic cause, which recurs after 24 hours of induced coma. The most common identifiable cause is inflammatory-autoimmune. Consequently, we present a case of NOSRSE related to SARS-CoV-2 vaccination as an opportunity to investigate the dysimmune origin of this pathology. CASE REPORT: We report the case of a 40-year-old male who presented at the emergency department with fever and headache with no clear source of infection. His personal history included bacterial meningitis in childhood without any sequelae and protein S deficiency without treatment at the time, as well as vaccination with ChAdOx1 nCoV-19 21 days earlier. He was initially diagnosed with a urinary tract infection and treated with cefuroxime. Two days later, he was taken back to the emergency department with confusional symptoms and tonic-clonic seizures. He did not respond to midazolam and finally required sedation and orotracheal intubation for refractory status epilepticus. While in hospital, he required a number of lines of antiepileptic drugs, ketamine, a ketogenic diet, immunotherapy and plasmapheresis in order to successfully limit NOSRSE. The aetiological study offered normal results for serology, antineuronal antibodies in serum and cerebrospinal fluid, transthoracic echocardiography, testicular ultrasound and computed tomographic angiography. Only the control MRI scan showed a diffuse and bilateral alteration of the right hemispheric cortex and thalamic pulvinar as the only finding. CONCLUSION: It is crucial to report suspected adverse reactions associated with SARS-CoV-2 vaccination, thereby allowing continued monitoring of the risk/benefit ratio of vaccination.

RESUMEN

PURPOSE OF REVIEW: This review aims to assess the treatment options for cancer-associated venous thromboembolism (VTE) based on the most robust level of evidence recommendations and suggestions based on expert opinion. RECENT FINDINGS: Several classes of anticoagulants have been studied in the treatment of cancer-associated thrombosis (CAT). Since the CLOT trial, guidelines recommend the use of low-molecular-weight heparin (LMWH) for the treatment of this condition. However, since 2018, some direct oral anticoagulants became an alternative first-line treatment for CAT. Three Xa antagonists (rivaroxaban, apixaban, and edoxaban) proved to be at least as effective as the LMWH strategy for the short-term prevention of VTE recurrence. The right choice of treatment in the context of anticoagulation strategy, thrombo-hemorrhagic risk management, and a patient's comorbidities represents a challenge. The correct management of CAT and a more individualized approach are needed to identify risk factors and offer the best treatment for each patient.

RESUMEN

PREMISE: To date, phylogenetic relationships within the monogeneric Brunelliaceae have been based on morphological evidence, which does not provide sufficient phylogenetic resolution. Here we use target-enriched nuclear data to improve our understanding of phylogenetic relationships in the family. METHODS: We used the Angiosperms353 toolkit for targeted recovery of exonic regions and supercontigs (exons + introns) from low copy nuclear genes from 53 of 70 species in Brunellia, and several outgroup taxa. We removed loci that indicated biased inference of relationships and applied concatenated and coalescent methods to infer Brunellia phylogeny. We identified conflicts among gene trees that may reflect hybridization or incomplete lineage sorting events and assessed their impact on phylogenetic inference. Finally, we performed ancestral-state reconstructions of morphological traits and assessed the homology of character states used to define sections and subsections in Brunellia. RESULTS: Brunellia comprises two major clades and several subclades. Most of these clades/subclades do not correspond to previous infrageneric taxa. There is high topological incongruence among the subclades across analyses. CONCLUSIONS: Phylogenetic reconstructions point to rapid species diversification in Brunelliaceae, reflected in very short branches between successive species splits. The removal of putatively biased loci slightly improves phylogenetic support for individual clades. Reticulate evolution due to hybridization and/or incomplete lineage sorting likely both contribute to gene-tree discordance. Morphological characters used to define taxa in current classification schemes are homoplastic in the ancestral character-state reconstructions. While target enrichment data allows us to broaden our understanding of diversification in Brunellia, the relationships among subclades remain incompletely understood.

RESUMEN

Fundamentos: Analizar cuáles son los antibióticos y los alimentos involucrados en las interaccionesfarmacocinéticas de absorción con mayor relevancia clínica y proponer su relación con la resistencia aantibióticos.Métodos: Revisión bibliográfica narrativa basada en la búsqueda bibliográfica de estudios publicados desdeel 1996 en PubMed.Resultados: Los antibióticos más afectados han sido las tetraciclinas, las quinolonas y los antituberculosos y,de los alimentos, la leche y sus derivados. Cuando se toman conjuntamente se produce una interacciónfarmacocinética de absorción que puede comprometer la biodisponibilidad del fármaco y/o de ciertosnutrientes, como el calcio. Este tipo de interacción puede ser un factor de riesgo de las resistencias.Conclusiones: Las interacciones entre los antibióticos y los alimentos existen y pueden ser un factor de riesgode las resistencias antimicrobianas. Para evitarlas se debe separar en el tiempo la administración de estosfármacos y los alimentos. El abuso en el empleo de estos fármacos y su mala utilización durante años haoriginado una fuerte presión selectiva en el mundo microbiano, favoreciendo el incremento de laspoblaciones resistentes y, consecuentemente, más patógenas. Es imprescindible que los profesionalessanitarios tengan formación específica e información actualizada para poder detectarlas y evitarlas. (AU)


Background: Analyze which are the antibiotics and foods involved in the absorption pharmacokineticinteractions with greater clinical relevance and propose their relationship with antibiotic resistance.Methods: Narrative bibliographic review based on the bibliographic search of studies published since 1996 inPubMed.Results: The most affected antibiotics have been tetracyclines, quinolones and antituberculous drugs and,from food, milk and its derivatives. When taken together, an absorption pharmacokinetic interaction occursthat can compromise the bioavailability of the drug and / or of certain nutrients, such as calcium. This type ofinteraction can be a risk factor for resistance.Conclusions: Interactions between antibiotics and food exist and can be a risk factor for antimicrobialresistance. To avoid them, the administration of these drugs and food must be separated in time. The abusein its use and its misuse for years has caused a strong selective pressure in the microbial world, favoring theincrease of resistant populations and, consequently, more pathogenic. It is essential that health professionalshave specific training and updated information to be able to detect and avoid them. (AU)

The standard rapid approach for the diagnosis of coronavirus disease 2019 (COVID-19) is the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA. The detection of specific anti-SARS-CoV-2 immunoglobulins is crucial for screening people who have been exposed to the virus, whether or not they presented symptoms. Recent publications report different methods for the detection of specific IgGs, IgMs, and IgAs against SARS-CoV-2; these methods mainly detect immunoglobulins in the serum using conventional techniques such as rapid lateral flow tests or enzyme-linked immunosorbent assay (ELISA). In this article, we report the production of recombinant SARS-CoV-2 spike protein and the development of a rapid, reliable, cost-effective test, capable of detecting immunoglobulins in serum and saliva samples. This method is based on interferometric optical detection. The results obtained using this method and those obtained using ELISA were compared. Owing to its low cost and simplicity, this test can be used periodically for the early detection, surveillance, detection of immunity, and control of the spread of COVID-19.
