Comparative genomics of Giardia duodenalis sub-assemblage AI beaver (Be-2) and human (WB-C6) strains show remarkable homozygosity, sequence similarity, and conservation of VSP genes.

Giardia duodenalis, a major cause of waterborne infection, infects a wide range of mammalian hosts and is subdivided into eight genetically well-defined assemblages named A through H. However, fragmented genomes and a lack of comparative analysis within and between the assemblages render unclear the molecular mechanisms controlling host specificity and differential disease outcomes. To address this, we generated a near-complete de novo genome of AI assemblage using the Oxford Nanopore platform by sequencing the Be-2 genome. We generated 148,144 long-reads with quality scores of > 7. The final genome assembly consists of only nine contigs with an N50 of 3,045,186 bp. This assembly agrees closely with the assembly of another strain in the AI assemblage (WB-C6). However, a critical difference is that a region previously placed in the five-prime region of Chr5 belongs to Chr4 of Be-2. We find a high degree of conservation in the ploidy, homozygosity, and the presence of cysteine-rich variant-specific surface proteins (VSPs) within the AI assemblage. Our assembly provides a nearly complete genome of a member of the AI assemblage of G. duodenalis, aiding population genomic studies capable of elucidating Giardia transmission, host range, and pathogenicity.

Anemia aplásica inducida por metimazol: presentación de caso / Methimazole Induced Aplastic Anemia: Case Report / Anemia aplástica induzida por metimazol: relato de caso

Introducción: los medicamentos antitiroideos son una de las alternativas terapéuticas en el tratamiento de la enfermedad de Graves. Sin embargo, pueden generar efectos adversos severos poco frecuentes en el plano hematológico, como la anemia aplásica, la cual se ha asociado con altas dosis de estos medicamentos, aunque con reversión de esta afección ante el retiro del medicamento. Descripción del caso: mujer de 38 años con antecedente de enfermedad de Graves en tratamiento con metimazol, quien consultó por síntomas como epistaxis anterior de difícil control, petequias, astenia e hiporexia. Se documentó pancitopenia en el hemo-grama, con posterior hallazgo en biopsia de médula ósea de aplasia medular, sin respuesta ante el retiro del metimazol y soporte transfusional. Posteriormente, la paciente falleció. Conclusión: la presentación de aplasia medular asociada con metimazol es poco común y se relaciona con altas dosis de este medicamento. En la mayoría de casos, el retiro de este agente genera recuperación clínica y celular. No obstante, en algu-nos pacientes persiste el compromiso hematológico que va desde importantes repercusiones clínicas hasta desenlaces fatales. Por lo tanto, el presente caso busca hace hincapié en la importancia de vigilar este efecto adverso ante el inicio de esta medicación

Introduction: Antithyroid drugs are one of the therapeutic alternatives in the treatment of Graves' dis-ease. However, it can generate severe but infrequent adverse effects at the hematological level, such as aplastic anemia, which has been associated with high doses of these drugs, although with reversal of this hematological condition when the drug is withdrawn. Case description: A 38-year-old woman with a his-tory of Graves' disease treated with methimazole, who consult for symptoms such as anterior epistaxis, petechiae, asthenia, and hyporexia. Pancytopenia is documented in the blood count, with a subsequent finding of bone marrow aplasia in bone marrow biopsy, without response to withdrawal of Methimazole and transfusion support. The patient subsequently died. Conclusion: The methimazole-associated bone marrow aplasia is uncommon and it ́s associated with high doses of methimazole, in most cases with-drawal of methimazole leads to clinical and cellular recovery. However, in some patients hematological involvement persists with significant clinical repercussions up to fatal outcomes. Therefore, this case seeks to highlight the importance of monitoring for this adverse effect before starting this medication

Introdução: as drogas antitireoidianas são uma das alternativas terapêuticas no tratamento da doença de Graves. No entanto, pode causar efeitos adversos graves, mas infrequentes, no nível hematológico, como a anemia aplástica, que tem sido associada a altas doses desses medicamentos, embora com rever-são desse quadro hematológico quando a droga é retirada. Descrição do caso: mulher de 38 anos com história de doença de Graves tratada com metimazol, que consultou por sintomas como epistaxe ante-rior de difícil controle, petéquias, astenia e hiporexia. A pancitopenia é documentada no hemograma, com achado posterior de aplasia da medula óssea na biópsia da medula óssea, sem resposta à retirada do metimazol e suporte transfusional. O doente faleceu posteriormente. Conclusão: a apresentação de aplasia da medula óssea associada ao metimazol é pouco frequente em associação com doses elevadas de metimazol. Na maioria dos casos, a retirada do metimazol conduz à recuperação clínica e celular. No entanto, nalguns doentes, o envolvimento hematológico persiste com repercussões clínicas significati-vas, podendo mesmo ocorrer desfechos fatais. Assim, o presente caso pretende realçar a importância da monitorização deste efeito adverso antes de iniciar esta medicação

Epileptic encephalopathies secondary to hypothalamic hamartomas treated with radiosurgery: A case series.

OBJECTIVE: Hypothalamic hamartomas are congenital lesions that typically present with gelastic seizures, refractory epilepsy, neurodevelopmental delay, and severe cognitive impairment. Surgical procedures have been reported to be effective in removing the hamartomas, however, they are associated with significant morbidity. Therefore, it is not considered a safe therapeutic modality. Image-guided robotic radiosurgery (CyberKnife® Radiosurgery System) has been shown to provide good outcomes without lasting complications. METHODS: This series of cases describes the clinical, radiological, radiotherapeutic, and postsurgical outcomes of five patients with epileptic encephalopathies secondary to hypothalamic hamartomas who were treated with CyberKnife®. RESULTS: All patients exhibited refractory epilepsy with gelastic seizures and were unsuitable candidates for surgical resection The prescribed dose ranged between 16 and 25 Gy, delivered in a single fraction for four patients and five fractions for one patient while adhering strictly to visual pathway constraints. After radiosurgery, four patients maintained seizure control (one with an Engel class Ia, three with an Engel class 1d), and another presented sporadic, nondisabling gelastic seizures (with an Engel class IIa). After 24-26 months of follow-up, in three patients, their intelligence quotient scores increased. No complications were reported. SIGNIFICANCE: This report suggests that Cyberknife may be a good option for treating hypothalamic hamartoma, particularly in cases where other noninvasive alternatives are unavailable. Nevertheless, additional studies are essential in order to evaluate the effectiveness of the technique in these cases.

Cost-effectiveness of the McGill interactive pediatric oncogenetic guidelines in identifying Li-Fraumeni syndrome in female patients with osteosarcoma.

BACKGROUND: Li-Fraumeni syndrome (LFS) is a penetrant cancer predisposition syndrome (CPS) associated with the development of many tumor types in young people including osteosarcoma and breast cancer (BC). The McGill Interactive Pediatric OncoGenetic Guidelines (MIPOGG) decision-support tool provides a standardized approach to identify patients at risk of CPSs. METHODS: We conducted a cost-utility analysis, from the healthcare payer perspective, to compare MIPOGG-guided, physician-guided, and universal genetic testing strategies to detect LFS in female patients diagnosed at an age of less than 18 years with osteosarcoma. We developed a decision tree and discrete-event simulation model to simulate the clinical and cost outcomes of the three genetic referral strategies on a cohort of female children diagnosed with osteosarcoma, especially focused on BC as subsequent cancer. Outcomes included BC incidence, quality-adjusted life-years (QALYs), healthcare costs, and incremental cost-utility ratios (ICURs). We conducted probabilistic and scenario analyses to assess the uncertainty surrounding model parameters. RESULTS: Compared to the physician-guided testing, the MIPOGG-guided strategy was marginally more expensive by $105 (-$516; $743), but slightly more effective by 0.003 (-0.04; 0.045) QALYs. Compared to MIPOGG, the universal testing strategy was $1333 ($732; $1953) more costly and associated with 0.011 (-0.043; 0.064) additional QALYs. The ICUR for the MIPOGG strategy was $33,947/QALY when compared to the physician strategy; the ICUR for universal testing strategy was $118,631/QALY when compared to the MIPOGG strategy. DISCUSSION: This study provides evidence for clinical and policy decision-making on the cost-effectiveness of genetic referral strategies to identify LFS in the setting of osteosarcoma. MIPOGG-guided strategy was most likely to be cost-effective at a willingness-to-pay threshold value of $50,000/QALY.

Subcutaneous phaeohyphomycosis due to Phaeoacremonium venezuelense: The first clinical case report in Costa Rica.

Phaeoacremonium is a genus of dematiaceous fungi that rarely causes human infections. We describe a case of subcutaneous infection in a 70-year-old diabetic man with lesions on the dorsum of the one foot. The agent was isolated, and for the final identification we performed matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and DNA sequencing. After diagnosis, the patient underwent curettage of the cyst and received 100mg of Itraconazole, twice daily for 6 months. Clinical resolution of the lesion was observed after treatment. This is the first case of infection by Phaeoacremonium venezuelense reported in Costa Rica.

Molecular detection of intestinal parasites in a rural community of Colombia: A one health approach to explore potential environmental-zoonotic transmission.

AIMS: Protozoan and helminth parasitic infections pose significant public health challenges, especially in developing countries with rural populations marked by suboptimal hygiene practices and socio-economic constraints. The parasites are the etiological agents of these infections and have a notably elevated global prevalence. Therefore, this study focuses on estimating the frequency and transmission dynamics of several parasitic species, including Blastocystis, Giardia, Cryptosporidium spp., Entamoeba histolytica, Ascaris lumbricoides, Trichuris trichiura, Taenia spp. and hookworms, within a rural community in southwest Colombia with a particular emphasis on the One Health framework, considering environmental and zoonotic transmission potentials. METHODS AND RESULTS: This study involved the analysis of 125 samples, encompassing human participants (n = 99), their domestic pets (dogs) (n = 24) and water sources (n = 2). Parasite detection was carried out utilizing a combination of microscopy and molecular techniques. Furthermore, the characterization of Blastocystis subtypes (STs) was achieved through Oxford Nanopore sequencing of the rRNA-18S gene. The investigation also entailed the examination of potential associations between intestinal parasitism and various sociodemographic factors. Results revealed a high frequency of parasitic infections when employing molecular methods, with Blastocystis (n = 109/87%), Giardia (n = 20/16%), Ancylostoma duodenale (n = 28/22%), Ancylostoma ceylanicum (n = 7/5.6%), E. histolytica (n = 6/4.8%), Cryptosporidium spp. (n = 12/9.6%) and even Taenia (n = 1/0.8%) detected. Cryptosporidium spp. was also identified in water samples. Coinfections were prevalent, with 57% (n = 70) of samples exhibiting single-parasite infections and 43% (n = 53) showing various degrees of polyparasitism, emphasizing the complexity of transmission dynamics. Blastocystis subtyping, conducted via Oxford Nanopore sequencing, revealed a diversity of subtypes and coexistence patterns, with ST2 being the most prevalent. CONCLUSIONS: This research underscores the importance of using molecular techniques for frequency estimation, particularly emphasizing the relevance of zoonotic transmission in parasitic infections. It highlights the significance of the One Health approach in comprehending the circulation of parasites among animals, humans and environmental sources, thereby directly impacting public health and epidemiological surveillance.

The Impact of Health Inequities on Population-Based Breast Cancer Survival in a Colombian Population, 2008-2015.

OBJECTIVE: To obtain breast cancer survival estimates in Manizales, Colombia, considering socioeconomic level, health insurance regime and residential area, while adjusting for age, histology and stage at diagnosis. METHODS: Analytical cohort study based on breast cancer incident cases recorded by the Population-based Manizales Cancer Registry between 2008-2015. Patients were followed-up for 60 months. Cause-specific survival was calculated using the Kaplan-Meier method for variables of interest, with the Wilcoxon-Breslow-Gehan test for differences. Cox multivariate regression models were fitted. RESULTS: 856 breast cancer cases were included. The 5-year cause-specific survival for the entire cohort was 78.2%. It was higher in women with special/exception health insurance, high socioeconomic level, <50 years old, ductal carcinoma, and stages I and II. Residential area did not impact survival. In Cox models, the subsidized health insurance regime (HR: 4.87 vs contributory) and low socioeconomic level (HR: 2.45 vs high) were predictors of the hazard of death in women with breast cancer, adjusted for age, histology, stage and interactions age-stage and insurance-stage. A positive interaction (synergistic effect modification) between health insurance regime and stage regarding to survival was observed. CONCLUSION: Socioeconomic factors significantly contribute to the inequities in breast cancer survival, independent of the stage at diagnosis. This suggests the need for comprehensive interventions to remove barriers to accessing the health system. This research provides evidence of survival gaps mediated by certain social determinants of health and generates data on the overall performance of the Colombian health system.

Optic nerve haemangioblastoma in association with von Hippel-Lindau syndrome: case report and literature review.

Optic nerve haemangioblastoma (ONH) is an uncommon, benign, non-meningothelial, mesenchymal tumour of unclear origin. Most are associated with von Hippel-Lindau (VHL) syndrome (71%), and only 40 cases have been reported in the medical literature. Most of the patients develop non-specific visual symptoms, including decreased visual acuity and/or loss of visual fields, exophthalmos, trigeminal neuralgia, and retroorbital pain. Optic nerve sheath meningioma and optic nerve glioma are among the differential diagnoses that may be considered in this location. Contrast-enhanced MRI is considered an optimal diagnostic tool, which helps to determine some characteristics that guide towards an adequate diagnosis and treatment. We present a 42-year-old patient with a history of VHL syndrome in whom a cerebellar lesion and optic nerve lesions were evidenced, and we did a review of the literature and case analysis.

Multidisciplinary management improves the genetic diagnosis of hereditary kidney diseases in the next generation sequencing (NGS) era.

BACKGROUND AND OBJECTIVE: Hereditary kidney diseases (HKD) are a frequent cause of chronic kidney disease, and their diagnosis has increased since the introduction of next generation sequencing (NGS). In 2018, the Multidisciplinary Unit for Hereditary Kidney Diseases of the Region of Murcia (UMERH-RM) was founded based on the genetic study of HKD. The objective of this study is to analyze the results obtained in the first 3 years of operation, and to analyze the clinical factors associated to a final genetic diagnosis. MATERIALS AND METHODS: All the patients studied with the HKD gene panel were included. The characteristics between those who obtained a final genetic diagnosis and those who did not were compared. RESULTS: A total of 360 patients were studied, detecting genetic variants in 164 not related patients (45.6%). 45 of these were variants of uncertain significance requiring a family co-segregation study, which was facilitated by the multidisciplinary unit. Overall, considering the results obtained with the NGS panel and the extended genomic studies, a final diagnostic yield of HRD of 33.3% (120/360) was achieved, and including incidental findings 35.6% (128/360). Two hundred and twenty-three patients with suspected Alport syndrome were studied. Diagnosis was confirmed in 28.5% (COL4A4 most frequent gene), more frequently women with an obvious compatible family history. They also had frequently microhematuria, although 5 patients without microhematuria confirmed the diagnosis. There were no differences in age, proteinuria, renal function, hearing loss, or ophthalmologic abnormalities. The most frequent finding in the renal biopsy was mesangial proliferation. We estimate that 39 patients avoided renal biopsy. A total of 101 patients with suspected PKD were also studied, 49.5% had a conclusive genetic result (most frequent gene PKD1), more frequently women, with larger kidney sizes (although 9 patients with normal kidney size confirmed diagnosis). Again, the most predictive characteristic of genetic outcome was family history. CONCLUSIONS: The implementation of an NGS panel for HKD, together with the multidisciplinary approach to cases, has improved the diagnostic performance of HKD. In our sample, autosomal dominant Alport syndrome is of highest incidence. Ophthalmological and auditory examinations did not contribute to the diagnosis. We have seen a significant decrease in the indication of renal biopsies thanks to molecular diagnosis. The multidisciplinary approach, with the active participation of nephrologists, paediatricians, clinical and molecular geneticists, with insistence on adequate patient phenotyping and review of their family history, offers a better interpretation of genetic variants, allowing reclassification of the diagnosis of some nephropathies, thus improving their management and genetic advice.

Retrospective Case Series of Cocaine-Associated Plasma Cell Orificial Mucositis.

Importance: Plasma cell orificial mucositis (PCOM) associated with cocaine use is an emerging, rare condition that has become a concern in Spain in recent years. Limited knowledge exists regarding this novel condition. Objectives: To delineate the clinicopathologic characteristics of this emerging entity and establish a novel approach in the differential diagnosis of cocaine-associated lesions. Design, Setting, and Participants: A descriptive, retrospective, multicenter case series of 10 patients diagnosed with cocaine-associated PCOM was conducted in Spain from April 2020 to March 2023. Main Outcomes and Measures: Patient demographic, clinical, histopathologic, and treatment data were collected. Results: A total of 10 patients (6 [60%] male; median [range] age, 45.5 [36-66] years) presenting with exudative ulcerated plaques were identified for this study. The lesions had raised and erythematous edges over the nostril and a median (range) evolution time of 9 (2-24) months. Septal or palate perforations were observed in 4 (40%) of the patients. Biopsies revealed a dense inflammatory infiltrate of plasma cells in the dermis without atypia and with eosinophils. All patients reported recent cocaine use. Three urine tests detected cocaine but found no presence of amphetamines or opiates. Six patients improved with corticosteroid therapy. Up to 60% of patients were lost to follow-up. Conclusions and Relevance: This case series describes the clinicopathologic characteristics of PCOM, an emerging entity associated with cocaine use in Spain, and demonstrates a novel approach in the differential diagnosis of cocaine-associated lesions. To date, cocaine-associated skin lesions have been reported as neutrophilic dermatoses and vasculitis. The appearance of a plasma cell infiltrate changes what has been described in the medical literature so far. PCOM is a benign condition of unknown cause characterized by a proliferative polyclonal plasma cell infiltrate. A comprehensive differential diagnosis workup is required to reach this exclusionary diagnosis. Several irritants have been documented in cases of PCOM, and a hypersensitivity mechanism has been proposed. Since the initial report of cocaine-associated PCOM in Spain, its incidence has experienced a surge in the country. The cause of this phenomenon may be attributed to newly unidentified adulterants. The administration of corticosteroids and discontinuation of cocaine use are the sole treatments that have demonstrated efficacy. Clinicians should be vigilant regarding this emerging condition and conduct inquiries into cocaine use. Additional research is required to clarify the pathophysiology of this emerging condition.

Evaluation of the Antibacterial, Anti-Cervical Cancer Capacity, and Biocompatibility of Different Graphene Oxides.

Cancer stands as one of the deadliest diseases in human history, marked by an inferior prognosis. While traditional therapeutic methods like surgery, chemotherapy, and radiation have demonstrated success in inhibiting tumor cell growth, their side effects often limit overall benefits and patient acceptance. In this regard, three different graphene oxides (GO) with variations in their degrees of oxidation were studied chemically and tissue-wise. The accuracy of the synthesis of the different GO was verified by robust techniques using X-ray photoelectron spectroscopy (XPS), as well as conventional techniques such as infrared spectroscopy (FTIR), RAMAN spectroscopy, and X-ray diffraction (XRD). The presence of oxygenated groups was of great importance. It affected the physicochemical properties of each of the different graphene oxides demonstrated in the presence of new vibrational modes related to the formation of new bonds promoted by the graphitization of the materials. The toxicity analysis in the Hep-2 cell line of graphene oxide formulations at 250 µg/mL on the viability and proliferation of these tumor cells showed low activity. GO formulations did not show high antibacterial activity against Staphylococcus aureus and Escherichia coli strains. However, the different graphene oxides showed biocompatibility in the subdermal implantation model for 30, 60, and 90 days in the biomodels. This allowed healing by restoring hair and tissue architecture without triggering an aggressive immune response.

Role of dexamethasone in controlling the proinflammatory cytokine cascade in the first episode of paediatric acute pyelonephritis.

AIM: Febrile urinary tract infection is a common bacterial infection in childhood. The kidney damage after acute pyelonephritis (APN) could be related to the stimulation of the proinflammatory response. We aimed to investigate the role of inflammatory cytokines and the effect of dexamethasone after a first episode of APN. METHODS: Subanalysis of the DEXCAR RCT in which children with confirmed APN (1 month-14 years) were randomly assigned to receive a 3 days course of either intravenous dexamethasone or placebo. Urinary cytokine levels at diagnosis and after 72 h of treatment were measured. RESULTS: Ninety-two patients were recruited. Younger patients, males and those with abnormalities in the ultrasound study or vesicoureteral reflux showed higher values of urinary cytokines. Patients with severe APN had higher Tumour Necrosis Factor (TNF)α levels (81.0 ± 75.8 vs. 33.6 ± 48.5 pg/mg creatinine, p = 0.015). Both intervention groups showed similar basal clinical characteristics, including urinary cytokine levels. Treatment reduced urinary cytokine levels irrespective of dexamethasone administration. Neither the intervention group nor the urinary cytokine levels modulated the development of kidney scars. CONCLUSION: Basal urinary cytokines were associated with age, abnormal ultrasound and vesicoureteral reflux. Patients with severe APN had higher TNFa urinary levels. Administration of dexamethasone in children with APN does not improve the control of the proinflammatory cytokine cascade.

Can we separately measure glenoid vs. humeral lateralization and distalization in reverse shoulder arthroplasty?

BACKGROUND: Lateralization and distalization in reverse shoulder arthroplasty (RSA) can be measured on anteroposterior (AP) radiographs using 2 previously described angles: lateralization shoulder angle (LSA) and distalization shoulder angle (DSA). However, these 2 angles measure global lateralization and distalization but do not allow to differentiate how much lateralization or distalization are attributable to the glenoid and the humerus. We hypothesized that new angles could allow us to separately measure glenoid vs. humeral lateralization and distalization. A more precise understanding of independent glenoid and humeral contributions to lateralization and distalization may be beneficial in subsequent clinical research. METHOD: Retrospective analysis of postoperative AP radiographs of 100 patients who underwent primary RSA for cuff-tear arthropathy, massive cuff tear, or glenohumeral osteoarthritis were analyzed. The new angles that we proposed use well-known bony landmarks (the acromion, glenoid, and humerus) and the most lateral point of the glenosphere, which we termed the "glenoid pivot point" (GPP). For lateralization, we used the GPP to split LSA into 2 new angles: glenoid lateralization angle (GLA) and humeral lateralization angle (HLA). For distalization, we introduced the modified distalization shoulder angle (mDSA) that can also be split into 2 new angles: glenoid distalization angle (GDA) and humeral distalization angle (HDA). Three orthopedic surgeons measured the new angles, using the online tool Tyche. Mean values with overall and individual standard deviations as well as intraclass correlation coefficients (ICCs) were calculated. RESULTS: Because the angles form a triangle, the following equations can be made: LSA = GLA + HLA, and mDSA = GDA + HDA. All angles showed excellent inter- and intraobserver reliability (ICC = 0.92-0.97) with low means of individual standard deviations that indicate a precision of 2° for each angle. CONCLUSION: Use of the most lateral part of the glenosphere (termed glenoid pivot point) allows us to separately measure glenoid vs. humeral lateralization and distalization. The 4 new angles (HLA, GLA, GDA, HDA) described in the present study can be used on true AP radiographs, routinely obtained after shoulder replacement, and the measured angles may be used with all types of reverse prostheses available.

Además, el 34,3% de los niños menores de seis meses estaban en riesgo de tener sobrepeso. Conclusiones: las condiciones sociodemográficas están determinadas por diferentes inequidades, bajos niveles de educación, vivienda inadecuada, consumo de agua no potable, así como por una alta prevalencia de malnutrición infantil.

Comparative analysis of ß-glucosidase activity in non-conventional yeasts.

The objective of this study was to evaluate the ß-glucosidase activity in the non-conventional yeasts under cellulose, glucose and sucrose substrates. The participation of the enzyme ß-glucosidase and its contribution to the enzymatic degradation of tannins is known. Within the classification of tannins are ellagitannins, molecules of gallic acid and ellagic acid, which are considered as nutraceutical compounds due to the properties that they present and that they can be used in the design of food and new drugs, synthesis of materials with antimicrobial capacity. The extracellular ß-glucosidase activity was mainly presented in the Candida and Pichia strains, being the glucose and sucrose media the most capable for inducing the activity that showed maximum values with P. pastoris in glucose (0.1682±0.00 µmol/min mg protein), and C. utilis in cellulose (0.1129±0.1349 µmol/min mg of protein), and sucrose (0.0657±0.0214 µmol/min mg protein). Additionally, I. terricola and P. kluyvery stood out in a qualitative cellulose degradation approach measured by Congo red method (9.60±0.04 mm and 9.20±0.05 mm respectively). These indicate that P. pastoris and C. utilis have potential as ß-glucosidase producers, especially when growing under complex carbon sources for biomass conversion, new biofuels production and polyphenol degradation with more manageable bioreactor process.

Lesión pulmonar aguda producida por transfusión (TRALI): Reporte de caso / Transfusion-induced acute lung injury (TRALI): Case report

Introducción: La lesión pulmonar aguda (TRALI) y la sobrecarga circulatoria (TACO) son las principales causas de morbilidad y mortalidad relacionadas con la transfusión. La TRALI se presenta durante o después de las transfusiones de plasma y sus derivados, o por inmunoglobulinas en alta concentración intravenosa; se asocia a procesos sépticos, cirugías y transfusiones masivas. La TACO es la exacerbación de manifestaciones respiratorias en las primeras 6 horas postransfusión. Reporte caso: Paciente de sexo masculino de 38 días de vida, ingresó al servicio de urgencias con un cuadro clínico de 8 días de evolución, caracterizado por dificultad respiratoria dado por retracciones subcostales y aleteo nasal sin otro síntoma asociado, con antecedentes de importancia de prematuridad y bajo peso al nacer. El reporte de hemograma arrojó cifras compatibles con anemia severa, por lo que requirió transfusión de glóbulos rojos empaquetados desleucocitados. El paciente presentó un cuadro respiratorio alterado en un periodo menor a 6 horas, por lo que se descartaron causas infecciosas y finalmente se consideró cuadro compatible con TRALI. Conclusiones: Se debe considerar una lesión pulmonar aguda relacionada con una transfusión de sangre si se produce una insuficiencia respiratoria aguda durante o inmediatamente después de la infusión de hemoderivados que contienen plasma.

Introduction: Acute lung injury (TRALI) and circulatory overload (TACO) are the main causes of transfusion-related morbidity and mortality. TRALI occurs during or after transfusions of plasma or its derivatives, or by immunoglobulins in high intravenous concentration; it is associated with septic processes, surgeries, and massive transfusions. TACO is the exacerbation of respiratory manifestations in the first 6 hours post transfusion. Case report: A 38-day-old male was admitted to the emergency department with clinical symptoms experienced over the course of 8 days and characterized by respiratory distress due to subcostal retractions and nasal flaring with no other associated symptoms. Important antecedents included prematurity and low birth weight. The hemogram report showed figures compatible with anemia, which benefited from transfusion of packed red blood cells without leukocytes. In a period of less than 6 hours, the patient presented altered respiratory symptoms, practitioners ruled out infectious causes and finally considered clinical signs compatible with TRALI. Conclusion: Acute lung injury related to blood transfusion should be considered if acute respiratory failure occurs during or immediately after infusion of plasma-containing blood products.

Síndrome de dificultad respiratoria aguda por Mycobacterium tuberculosis de rápido crecimiento en una mujer con virus linfotrópico T humano tipo I-II / Acute respiratory distress syndrome due to rapidly growing Mycobacterium tuberculosis in a woman with human T-lymphotropic virus type I-II

La tuberculosis es una infección de distribución mundial con una alta morbimortalidad en países subdesarrollados. Presentamos el caso de una mujer de 55 años con cuadro de dos meses de adenomegalias cervicales, pérdida de peso y fiebre con posterior disnea de esfuerzo progresiva. Ingresó por urgencias en falla ventilatoria y hallazgos radiológicos compatibles con síndrome de dificultad respiratoria aguda (SDRA) requiriendo ventilación mecánica invasiva. Se demostró infección por M. tuberculosis por PCR en tiempo real GeneXpert MTB/RIF Ultra y en cultivo de medio líquido de esputo, con crecimiento en tiempo menor a tres días. La biopsia de las adenomegalias confirmó linfoma de células T periférico asociado a infección por virus linfotrópico T humano tipo I-II, presentando una evolución tórpida a pesar del esquema quimioterapéutico.

Tuberculosis is a globally distributed infection with high morbidity and mortality in underdeveloped countries. We present the case of a 55-year-old woman with a 2-month history of cervical lymph nodes, weight loss, and fever with subsequent progressive exertional dyspnea. She was admitted to the emergency department with ventilatory failure and radiological findings compatible with acute respiratory distress syndrome (ARDS) requiring invasive mechanical ventilation. M. tuberculosis infection was proved by a real-time PCR GeneXpert MTB/RIF Ultra and in culture of sputum liquid medium, with growth in less than 3 days. The biopsy of the lymph nodes revealed peripheral T-cell lymphoma associated with infection by human T-lymphotropic virus type I-II, presenting a torpid evolution despite the chemotherapy regimen.

Human Resource Management in the Gig Economy: towards a new configuration?

The context of the Gig Economy involves a break in the standard employment relationship between employees and employer; and a questioning of the role of Human Resources management (HR) in charge of managing this link. This article aims to analyse the role and configuration of HR management in the context of the Gig Economy From the contingent configurational approach, the way in which HR practices are combined and configured to contribute to performance and manage the relationship with the individuals who participate in this economy is argued. It is found that the labour relationship between companies and gig workers is characterized by being transactional and symbiotic based on the utilitarian premise of mutual benefit. For this reason, for this context, an HR configuration oriented towards the market or maximizing productivity and the fulfilment of agreements would predominate. JEL CLASSIFICATION J0I; J2I; MI2

O contexto da Gig Economy implica uma ruptura da relação de emprego padrão entre empregados e empregador e um questionamento do papel da gestão de Recursos Humanos (RH) no gerenciamento desse vínculo. Este artigo tem como objetivo analisar o papel e a configuração da GRH no contexto da Gig Economy. A partir de uma abordagem configuracional contingente, ele argumenta como as práticas de RH são combinadas e configuradas para contribuir para o desempenho e gerenciar o relacionamento com os indivíduos que participam dessa economia. O estudo conclui que a relação de emprego entre as empresas e os trabalhadores autônomos é caracterizada como transacional e simbiótica, com base na premissa utilitarista do benefício mútuo. Assim, nesse contexto, predominaria uma configuração de RH orientada para o mercado ou para maximizar a produtividade e o cumprimento de acordos. CLASSIFICAÇÃO JEL J01; J21; M12

El contexto de la Gig Economy supone una ruptura de la relación laboral estándar entre empleados y empleador; y un cuestionamiento sobre la función de la gestión de Recursos Humano (RR.HH.) encargada de gestionar dicho vínculo. El presente artículo tiene como objetivo analizar la función y configuración de la gestión de RR.HH. en el contexto de la Gig Economy. Desde el enfoque configuracional contingente se argumenta el modo en el que las prácticas de RR.HH. se combinan y configuran para aportar al desempeño y gestionar el relacionamiento con los individuos que participan de esta economía. Se encuentra que la relación laboral entre las empresas y los trabajadores gig se caracteriza por ser transaccional y simbiótica basada en la premisa utilitaria del beneficio mutuo. Por ello, para este contexto predominaría una configuración de RR.HH. orientada hacia el mercado o en maximizar la productividad, y al cumplimiento de acuerdos. CLASIFICACIÓN JEL J0I; J2I; MI2

Neopentecostalismo, teología de la prosperidad y neoliberalismo. Hacia una lógica religiosa para el Homo oeconoimicus

El presente escrito tiene por objetivo demostrar que la relación entre la teología de la prosperidad, que se toma aquí específicamente en su expresión neopentecostal, y el neoliberalismo, entendido desde su dimensión de fuerza productora de subjetividad, se ha fortalecido dentro del actual marco de reproducción sistémica del capitalismo. Para esto se divide el escrito en tres partes: la primera, que se encarga de exponer conceptualmente el neopentecostalismo; la segunda, donde se expone la teología de la prosperidad; y, por último, aquella que trabaja la manera en que el fenómeno religioso neopentecostal, como ejemplo de fe de la prosperidad, se vincula con el neoliberalismo. De este modo, y a partir del método documental-bibliográfico, se puede evidenciar cómo es que el actual viraje del capitalismo se dirige hacia ciertas prácticas y discursos religiosos, de modo que pueda capturarlos y volverlos a su favor, ya que dichas prácticas y discursos permiten, entre otras cosas, una alternativa para curar, momentáneamente, el sufrimiento subjetivo que padece el Homo oeconomicus por vivir como manda el sistema.

The purpose of this paper is to demonstrate the relationship theology of prosperity, which is specifically taken in its neo-Pentecostal expression, and neoliberalism as necessary within the current framework of systemic reproduction of capitalism. For this, the writing is divided into three parts: the first, which is responsible for conceptually exposing neo-Pentecostalism; the second, where the theology of prosperity is exposed; and, finally, the one that works on the way in which the neo-Pentecostal religious phenomenon, as an example of faith in prosperity, is linked to neoliberalism. In this way, it can be evidenced how the current turn of capitalism is directed towards religion, so that it can capture it and turn it in its favor, since it allows an alternative to cure, momentarily, the subjective suffering of Homo oeconomicus that inhabits within the system that he himself produced.

O objetivo deste artigo é demonstrar que a relação entre a teologia da prosperidade, específicamente tomada em sua expressão neopentecostal, e o neoliberalismo, entendido a partir de sua dimensão de força produtora de subjetividade, tem se fortalecido no atual quadro de reprodução do capitalismo. Para isso, o escrito está dividido em três partes: a primeira, que se encarrega de expor conceitualmente o neopentecostalismo; a segunda, onde é exposta a teologia da prosperidade; e, por fim, a que trabalha a maneira como o fenômeno religioso neopentecostal, como exemplo de fé na prosperidade, se vincula ao neoliberalismo. Desta forma, e a partir do método bibliográfico-documental, pode-se evidenciar como a atual virada do capitalismo está voltada para a religião, de modo que possa capturá-la e transformá-la a seu favor, pois permite uma alternativa para curar, momentaneamente, o sofrimento subjetivo sofrido pelo homo oeconomicus por viver como manda o sistema.
