Translation and linguistic validation of the Sheffield Profile for Assessment and Referral for Care (SPARC) to Colombian Spanish.

OBJECTIVES: We aimed to translate and linguistically and cross-culturally validate Sheffield Profile for Assessment and Referral for Care (SPARC) in Spanish for Colombia (SPARC-Sp). METHODS: The linguistic validation of SPARC followed a standard methodology. We conducted focus groups to assess the comprehensibility and feasibility. The acceptability was assessed using a survey study with potential users. RESULTS: The comprehensibility assessment showed that additional adjustments to those made during the translation-back-translation process were required to apply SPARC-Sp in rural and low-schooled populations. It also identified the need for alternative administration mechanisms for illiterate people. The acceptability survey showed that potential users found SPARC-Sp as not only acceptable but also highly desirable. However, they desired to expand the number of items in all domains. SIGNIFICANCE OF RESULTS: Beyond the semantic and conceptual validity attained through the back-translation process, actual cultural validity could be acquired thanks to the comprehensibility tests. Although extending the instrument is something potential users would like to do, it would make it less feasible to utilize the SPARC-Sp in clinical settings. Nonetheless, the instrument might benefit from the inclusion of a domain that evaluates challenges encountered when accessing the health-care system. For communities lacking literacy, alternate administration methods must also be considered.

Desenlaces adversos perioperatorios en ancianos con fractura de cadera, antes y después de la implementación de un protocolo de ortogeriatría / Adverse perioperative outcomes in elderly patients with hip fracture before and after the implementation of an orthogeriatric protocol

Introducción: la fractura de cadera en adultos mayores constituye un problema de salud importante, ya que está asociada a mayor morbilidad y mortalidad. Por esta razón, se han creado protocolos de ortogeriatría para su abordaje, los cuales reportan resultados favorables.Objetivo: evaluar los desenlaces adversos perioperatorios en adultos mayores con fractura de cadera antes y después de la implementación de un protocolo de evaluación geriátrica integral (EGI).Metodología: estudio de casos y controles realizado en 136 pacientes (casos: 43; controles: 93) >65 años con fractura de cadera que fueron atendidos en un hospital de referencia entre 2020 y 2021 (casos), y 2015 y 2017 (controles). Se determinaron diferencias entre grupos mediante un análisis bivariado usando las pruebas de chi cuadrado o exacta de Fisher en variables categóricas, y las pruebas t de student o de Wilcoxon de los rangos con signo en variables continuas según la distribución de los datos.Resultados: los desenlaces adversos perioperatorios ocurrieron en el 62,7% de los casos y el 84,0% de los controles (p=0,007; OR:0,32; IC95%:0,13-0,73). La mediana de duración de la estancia hospitalaria fue 10 y 17 días en los casos y controles, respectivamente (RIQ: 8-14; RIQ 11-26), mientras que el tiempo entre el ingreso a urgencias y la cirugía fue 7 días (RIQ:5-11) y 11 días (RIQ:8-17), respectivamente (p=0.002). Conclusiones: la implementación de la EGI redujo los desenlaces adversos por fractura de cadera, principal-mente la duración de la estancia hospitalaria y el tiempo entre el ingreso y la cirugía, donde se observaron diferencias estadísticamente significativas entre ambos grupos

Introduction: Hip fracture in elderly patients is a major health concern, as it is associated with increased morbidity and mortality. For this reason, orthogeriatric protocols have been created to approach it, reporting favorable outcomes.Objective: To evaluate adverse perioperative outcomes in elderly patients with hip fractures before and after the implementation of a comprehensive geriatric assessment (CGA) protocol.Methodology: Case-control study performed on 136 patients (cases: 43; controls: 93) >65 years old with a hip fracture, who were treated at a referral hospital between 2020 and 2021 (cases) and 2015 and 2017 (controls). Differences between groups were determined through bivariate analysis using Fisher's chi-square or exact tests on categorical variables, and Student's t-test or Wilcoxon signed-rank test on continuous variables depending on the distribution of the data.Results: Adverse perioperative outcomes occurred in 62.7% of cases and 84.0% of controls (p=0.007; OR:0.32; 95%CI:0.13-0.73). The median length of hospital stay was 10 and 17 days in cases and controls, respectively (IQR: 8-14; IQR 11-26), while the time between ED admission and surgery was 7 days (IQR:5-11) and 11 days (IQR:8-17), respectively (p=0.002).Conclusions: The implementation of the CGA protocol reduced adverse outcomes associated with hip fracture, mainly the length of hospital stay and the time between admission and surgery, in which statistically significant differences were observed between both groups

Hemorragia alveolar en síndrome febril tropical: reporte de caso de leptospirosis con compromiso pulmonar / Alveolar hemorrhage in febril-tropical syndrome: case report of leptospirosis with lung commitment

Resumen La leptospirosis en una enfermedad infecciosa importante en el diagnóstico diferencial de un paciente con síndrome ictérico hemorrágico, especialmente en países de ubicación tropical como Colombia. A continuación, se presenta el caso de un paciente masculino de 21 años, con cuadro clínico agudo caracterizado por presencia de fiebre y elevación de bilirrubinas, asociado a diarrea y trombocitopenia. Inicialmente se hizo diagnóstico presuntivo de dengue, sin embargo, durante su evolución presentó hemorragia y dificultad respiratoria asociada a secreción hemática con necesidad de intubación endotraqueal, por lo que se solicitó serologia IgM seriada de leptospira pensando en esta entidad como diagnóstico diferencial luego de indagar antecedentes epidemiológicos, la cual tuvo reporte positivo. Es importante conocer este tipo de casos debido a la presentación de compromiso pulmonar como una manifestación rara pero altamente asociada a mortalidad. Finalmente, con manejo de soporte y antibiótico adecuado se obtuvo una buena evolución clínica de este paciente.

Abstract Leptospirosis is a relevant infectious disease when there is a patient with an ictero-hemorrhagic syndrome, especially in tropical countries such as Colombia. The following is the case of a 21-year-old male patient, with an acute clinical picture given by fever, elevated bilirubin, associated with diarrhea and thrombocytopenia. Initially, a presumptive diagnosis of dengue was made. However, during his evolution, he presented hemorrhage and respiratory distress with a hematic secretion that required endotracheal intubation. After inquiring about the epidemiological data, leptospirosis was considered a differential diagnosis. Serial serology for leptospira IgM was requested and was positive. It is essential to know this type of case due to pulmonary affections as a rare manifestation but highly associated with mortality. Finally, with adequate antibiotic and supportive management, a good clinical evolution of this patient was obtained.

Toxic Activity, Molecular Modeling and Docking Simulations of Bacillus thuringiensis Cry11 Toxin Variants Obtained via DNA Shuffling.

The Cry11 family belongs to a large group of δ-endotoxins that share three distinct structural domains. Among the dipteran-active toxins referred to as three-domain Cry11 toxins, the Cry11Aa protein from Bacillus thuringiensis subsp. israelensis (Bti) has been the most extensively studied. Despite the potential of Bti as an effective biological control agent, the understanding of Cry11 toxins remains incomplete. In this study, five Cry11 variants obtained via DNA shuffling displayed toxic activity against Aedes aegypti and Culex quinquefasciatus. Three of these Cry11 variants (8, 23, and 79) were characterized via 3D modeling and analysis of docking with ALP1. The relevant mutations in these variants, such as deletions, insertions and point mutations, are discussed in relation to their structural domains, toxic activities and toxin-receptor interactions. Importantly, deletion of the N-terminal segment in domain I was not associated with any change in toxic activity, and domain III exhibited higher sequence variability than domains I and II. Variant 8 exhibited up to 3.78- and 6.09-fold higher toxicity to A. aegypti than Cry11Bb and Cry11Aa, respectively. Importantly, variant 79 showed an α-helix conformation at the C-terminus and formed crystals retaining toxic activity. These findings indicate that five Cry11 variants were preferentially reassembled from the cry11Aa gene during DNA shuffling. The mutations described in loop 2 and loop 3 of domain II provide valuable information regarding the activity of Cry11 toxins against A. aegypti and C. quinquefasciatus larvae and reveal new insights into the application of directed evolution strategies to study the genetic variability of specific domains in cry11 family genes.
