[Translated article] Better results in consolidation of hallux metatarsophalangeal arthrodesis with dorsal plate and interfragmentary compression screw.

BACKGROUND AND AIMS: The first metatarsophalangeal joint arthrodesis is indicated for the treatment of various pathologies as a technique to reduce pain and improve the support of the first radius. Numerous surgical techniques and fixation methods have been described, with the combination of a dorsal plate and an interfragmentary screw being the one that has shown to be the most stable construct in biomechanical studies. Our aim is to analyze the radiological results after metatarsophalangeal arthrodesis of the hallux using a dorsal plate associated or not with an interfragmentary screw. The differences in terms of consolidation rates and complications in patients diagnosed with hallux rigidus, hallux valgus, hallux varus and failure of previous surgeries were evaluated. MATERIALS AND METHODS: A retrospective cohort study of 55 patients with a mean age of 65.10 years in whom a dorsal plate was used was performed. Patients were divided into two groups depending on whether or not an interfragmentary screw was used. The minimum follow-up was 6 months after surgery. The assessment of the pre and postoperative radiological results was based on the variation of the hallux angle, the intermetatarsal angle and the dorsal metatarsophalangeal angle of the hallux, as well as the cases of nonunion identified in each study group. RESULTS: The radiological results, statistically significant differences (p<0.05) were only found in the dorsal metatarsophalangeal angle between both study groups. No statistically significant differences were found regarding the radiological evaluation of the pre and postoperative hallux angle and intermetatarsal angle. An equal decrease of each angles was observed in both study groups. Regarding the consolidation rate, statistically significant differences (p<0.05) were found between group A, which associated an interfragmentary screw, presenting a consolidation rate of 92%, and group B, which did not associate an interfragmentary screw, and that presented a union rate of 63%. CONCLUSION: Hallux metatarsophalangeal arthrodesis of the hallux with a dorsal plate and interfragmentary screw show best results regarding consolidation rate and complications compared to those cases in which an interfragmentary screw was not used.

A Series of 69 COVID-related Dermatoses With Biopsy, Immunohistochemistry With Anti-spike 3, in situ Hybridization and PCR: A Critical Reappraisal of Viral Involvement in COVID-19 Skin Lesions / Serie de 69 dermatosis relacionadas con la COVID con biopsia, estudio inmunohistoquímico con anti-spike 3, hibridación in situ y PCR: Una revisión crítica de la afectación cutánea relacionada con la COVID-19

Background Despite the large number of articles published on skin lesions related to COVID-19, clinicopathological correlation has not been performed consistently and immunohistochemistry to demonstrate spike 3 protein expression has not been validated through RT-PCR. Material and method We compiled 69 cases of patients with confirmed COVID-19, where skin lesions were clinically and histopathologically studied. Immunohistochemistry (IHC) and RT-PCR was performed in skin biopsies. Results After a careful review of the cases, 15 were found to be dermatosis not related to COVID-19, while the rest of the lesions could be classified according to their clinical characteristics as vesicular (4), maculopapular eruptions (41), urticariform (9), livedo and necrosis (10) and pernio-like (5). Although histopathological features were similar to previously reported results, we found two previously unreported findings, maculopapular eruptions with squamous eccrine syringometaplasia and neutrophilic epitheliotropism. IHC showed in some cases endothelial and epidermal staining but RT-PCR was negative in all the tested cases. Thus, direct viral involvement could not be demonstrated. Conclusions Despite presenting the largest series of confirmed COVID-19 patients with histopathologically studied skin manifestations, direct viral involvement was difficult to establish. Vasculopathic and urticariform lesions seem to be those more clearly related to the viral infection, despite IHC or RT-PCR negative results failed to demonstrate viral presence. These findings, as in other dermatological areas, highlight the need of a clinico-pathological correlation to increase knowledge about viral involvement in COVID-19 skin-related lesions (AU)

Antecedentes A pesar del gran número de artículos publicados sobre las lesiones cutáneas relacionadas con la COVID-19, no se ha realizado una correlación clinicopatológica de manera consistente, y no ha sido validado el estudio de inmunohistoquímica para demostrar la expresión de la proteína spike 3 mediante RT-PCR. Material y métodos Recopilamos 69 casos de pacientes con COVID-19 confirmada, en los que se estudiaron las lesiones cutáneas a nivel clínico e histopatológico, habiéndose realizado la prueba inmunohistoquímica (IHQ) y RT-PCR en las biopsias cutáneas. Resultados Tras una revisión detallada de los casos, en 15 de ellos se encontró que la dermatosis no guardaba relación con la COVID-19, mientras que el resto de las lesiones podrían clasificarse de acuerdo con sus características clínicas como vesiculares (4), erupciones maculopapulares (41), urticariformes (9), livedo y necrosis (10) y de tipo perniosis (5). Aunque las características histopatológicas fueron similares a los resultados previamente reportados, encontramos dos hallazgos no reportados previamente: erupciones maculopapulares con siringometaplasia ecrina escamosa y epiteliotropismo neutrofílico. La IHQ reflejó en ciertos casos tinción endotelial y epidérmica, pero la prueba RT-PCR fue negativa en todos los casos probados. Por ello no pudo demostrarse el compromiso viral directo. Conclusiones A pesar de presentar la mayor serie de pacientes con COVID-19 confirmada y manifestaciones cutáneas histopatológicamente estudiadas, el compromiso viral directo fue difícil de establecer. Las lesiones vasculopáticas e urticariformes parecen ser las más claramente relacionadas con la infección viral, a pesar de que los resultados negativos de la IHQ o RT-PCR no pudieron demostrar la presencia viral (AU)

Design of a Multi-Epitope Vaccine against Tuberculosis from Mycobacterium tuberculosis PE_PGRS49 and PE_PGRS56 Proteins by Reverse Vaccinology.

Tuberculosis is a disease caused by Mycobacterium tuberculosis, representing the second leading cause of death by an infectious agent worldwide. The available vaccine against this disease has insufficient coverage and variable efficacy, accounting for a high number of cases worldwide. In fact, an estimated third of the world's population has a latent infection. Therefore, developing new vaccines is crucial to preventing it. In this study, the highly antigenic PE_PGRS49 and PE_PGRS56 proteins were analyzed. These proteins were used for predicting T- and B-cell epitopes and for human leukocyte antigen (HLA) protein binding efficiency. Epitopes GGAGGNGSLSS, FAGAGGQGGLGG, GIGGGTQSATGLG (PE_PGRS49), and GTGWNGGKGDTG (PE_PGRS56) were selected based on their best physicochemical, antigenic, non-allergenic, and non-toxic properties and coupled to HLA I and HLA II structures for in silico assays. A construct with an adjuvant (RS09) plus each epitope joined by GPGPG linkers was designed, and the stability of the HLA-coupled construct was further evaluated by molecular dynamics simulations. Although experimental and in vivo studies are still necessary to ensure its protective effect against the disease, this study shows that the vaccine construct is dynamically stable and potentially effective against tuberculosis.

The comparative efficacy and safety of biologics and small molecules for treating patients with ulcerative colitis in Portugal: a systematic literature review and network meta-analysis.

OBJECTIVE: The use of biological drugs to treat ulcerative colitis (UC) represents a clear added value; nevertheless, many patients do not have a sustained response to these drugs. Small molecules were recently approved for the treatment of UC in Portugal. This network meta-analysis aimed to compare the efficacy and safety of the different therapies, including biological and small molecules, in patients prior exposed to biological treatment. MATERIALS AND METHODS: A systematic review of the literature was performed on January 6, 2022, identifying all the relevant reports about the efficacy and safety of biologics (adalimumab, golimumab, infliximab, vedolizumab, ustekinumab) and small molecules (upadacitinib, filgotinib, tofacitinib) in the treatment of UC in Portugal. Network meta-analysis (NMA) was conducted using Bayesian Markov Chain Monte Carlo simulations. Results were presented in median Odds Ratio and Surface Under the Cumulative RAnking (SUCRA) score for each treatment. RESULTS: Treatment of UC is divided into two phases: induction and maintenance. Upadacitinib 45 mg was the most efficacious therapy in achieving clinical remission and response and endoscopic improvement in the induction phase. Concerning the maintenance phase, upadacitinib 30 mg performed better than ustekinumab formulations in clinical remission and response, and endoscopic improvement. Regarding safety, there were no significant differences between all the drugs included in the analysis. CONCLUSIONS: This network meta-analysis showed that upadacitinib reflects better efficacy compared to the available treatments for bio-exposed patients with moderate to severe UC. The safety profile is comparable to the other drugs.

Photoelectron Spectroscopy of Oppositely Charged Molecular Switches in the Aqueous Phase: Theory and Experiment.

XUV photoelectron spectroscopy (XPS) is a powerful method for investigating the electronic structures of molecules. However, the correct interpretation of results in the condensed phase requires theoretical models that account for solvation. Here we present experimental aqueous-phase XPS of two organic biomimetic molecular switches, NAIP and p-HDIOP. These switches are structurally similar, but have opposite charges and thus present a stringent benchmark for solvation models which need to reproduce the observed ΔeBE = 1.1 eV difference in electron binding energy compared to the 8 eV difference predicted in the gas phase. We present calculations using implicit and explicit solvent models. The latter employs the average solvent electrostatic configuration and free energy gradient (ASEC-FEG) approach. Both nonequilibrium polarizable continuum models and ASEC-FEG calculations give vertical binding energies in good agreement with the experiment for three different computational protocols. Counterions, explicitly accounted for in ASEC-FEG, contribute to the stabilization of molecular states and reduction of ΔeBE upon solvation.

Organization and Characterization of the Promoter Elements of the rRNA Operons in the Slow-Growing Pathogen Mycobacterium kumamotonense.

The slow-growing, nontuberculous mycobacterium Mycobacterium kumamotonense possesses two rRNA operons, rrnA and rrnB, located downstream from the murA and tyrS genes, respectively. Here, we report the sequence and organization of the promoter regions of these two rrn operons. In the rrnA operon, transcription can be initiated from the two promoters, named P1 rrnA and PCL1, while in rrnB, transcription can only start from one, called P1 rrnB. Both rrn operons show a similar organization to the one described in Mycobacterium celatum and Mycobacterium smegmatis. Furthermore, by qRT-PCR analyses of the products generated from each promoter, we report that stress conditions such as starvation, hypoxia, and cellular infection affect the contribution of each operon to the synthesis of pre-rRNA. It was found that the products from the PCL1 promoter of rrnA play a pivotal role in rRNA synthesis during all stress conditions. Interestingly, the main participation of the products of transcription from the P1 promoter of rrnB was found during hypoxic conditions at the NRP1 phase. These results provide novel insights into pre-rRNA synthesis in mycobacteria, as well as the potential ability of M. kumamotonense to produce latent infections.

Management of acute stroke. Specific nursing care and treatments in the stroke unit.

OBJECTIVE: This study provides a series of updated, evidence-based recommendations for the management of acute stroke. We aim to lay a foundation for the development of individual centres' internal protocols, serving as a reference for nursing care. METHODS: We review the available evidence on acute stroke care. The most recent national and international guidelines were consulted. Levels of evidence and degrees of recommendation are based on the Oxford Centre for Evidence-Based Medicine classification. RESULTS: The study describes prehospital acute stroke care, the operation of the code stroke protocol, care provided by the stroke team upon the patient's arrival at hospital, reperfusion treatments and their limitations, admission to the stroke unit, nursing care in the stroke unit, and discharge from hospital. CONCLUSIONS: These guidelines provide general, evidence-based recommendations to guide professionals who care for patients with acute stroke. However, limited data are available on some aspects, showing the need for continued research on acute stroke management.

Antecedentes y objetivos: En el desarrollo del pie plano valgo adquirido del adulto ha cobrado gran importancia el fallo de la columna medial, y no tanto la rotura del tibial posterior, siendo principalmente la lesión del ligamento en hamaca calcaneonavicular (spring ligament) el determinante del desarrollo de esta deformidad. Nuestro objetivo es analizar los resultados clínico-radiológicos de la reparación del ligamento en hamaca y valorar la utilidad e integración de las cuñas de titanio poroso en las osteotomías a las que se asocia la reparación ligamentosa. Material y métodos: Realizamos un estudio retrospectivo de 23 casos con una edad media de 63 años, diagnosticados de pie plano valgo adquirido del adulto estadio IIB de la clasificación RAM tras fallo de tratamiento ortoprotésico, valorando los resultados clínicos mediante la escala de la American Orthopaedic Foot and Ankle Society y los resultados radiológicos pre- y postoperatorios basándose en la variación de los ángulos estudiados (cobertura talonavicular y ángulo talar - 1.° metatarsiano en la proyección dorsoplantar y línea de Meary en la proyección lateral). Resultados: Los puntuación media en escala de la American Orthopaedic Foot and Ankle Society pasó de 52±10 preoperatorio a 88±6 (p<0,05). En cuanto a los resultados radiológicos, se demostró una mejoría estadísticamente significativa (p<0,05) en la variación de los ángulos en el postoperatorio. Conclusiones: La reparación de los estabilizadores mediales, asociada a técnicas óseas ofrece excelentes resultados clínico-radiológicos en el tratamiento del pie plano valgo adquirido del adulto estadio IIB.Además, las cuñas de titanio poroso presentan una adecuada integración, evitando los problemas de pinzamiento de los peroneos asociada al uso de placas y la necesidad posterior de retirada.(AU)

La muestra estuvo conformada por 390 estudiantes de una universidad pública peruana. Se aplicó el Índice de Calidad de Vida de Mezzich (Alfa de Cronbach= 0,870). Los datos fueron recogidos antes y durante la pandemia . Resultados: La edad promedio de los estudiantes fue de 19.3+1.6 años, 73 % de sexo femenino, 98,7 % solteros, 90,3 % convivía con la familia y 87,9 % no trabajaba. El 24,9 % estudiaba medicina humana, 16,7 % enfermería, 11,8 % trabajo social y el 46,6 % restante estudió otras carreras. Al comparar la calidad de vida general y sus dimensiones de los estudiantes, se encontró que durante la pandemia las puntuaciones promedio disminuyeron con diferencias estadísticas significativas, a excepción de Bienestar físico y Apoyo social-emocional. Así mismo, hubo disminución de la calidad de vida en las variables ocupación, forma de convivencia y carrera (p<0.05). Los varones obtuvieron mejores puntuaciones de calidad de vida, a excepción de la dimensión Funcionamiento interpersonal (p<0.05). Conclusiones: la calidad de vida de los estudiantes universitarios en la pandemia de Covid-19 se vio afectada en su vida personal y en su preparación como futuros profesionales, enfrentando grandes retos de adaptación; siendo las mujeres las más afectadas.

ABSTRACT Objective: To compare the quality of life of the university student before and during the Covid-19 pandemic. Materials and methods: Descriptive, prospective, comparative. The sample consisted of 390 students from a Peruvian public university. The Mezzich Quality of Life Index (Cronbach's Alpha = 0.870) was applied. The data was collected before and during the Covid-19 pandemic. Results: The average age of the students was 19.3 + 1.6 years, 73 % female, 98.7 % single, 90.3 % lived with the family and 87.9% did not work. 24.9 % studied human medicine, 16.7 % nursing, 11.8 % social work and the remaining 46.6 % studied other careers. When comparing the students' general quality of life and its dimensions, it was found that during the pandemic, the average scores decreased with statistically significant differences, except for Physical well-being and Social-emotional support. Likewise, there was a decrease in the quality of life in the variable's occupation, the form of coexistence, and career (p <0.05). Men obtained better quality of life scores except for the Interpersonal Functioning dimension (p <0.05). Conclusions: the quality of life of university students in the Covid-19 pandemic was affected in their personal life and their preparation as future professionals, facing great adaptation challenges, with women being the most affected.

The Flp type IV pilus operon of Mycobacterium tuberculosis is expressed upon interaction with macrophages and alveolar epithelial cells.

The genome of Mycobacterium tuberculosis (Mtb) harbors the genetic machinery for assembly of the Fimbrial low-molecular-weight protein (Flp) type IV pilus. Presumably, the Flp pilus is essential for pathogenesis. However, it remains unclear whether the pili genes are transcribed in culture or during infection of host cells. This study aimed to shed light on the expression of the Flp pili-assembly genes (tadZ, tadA, tadB, tadC, flp, tadE, and tadF) in Mtb growing under different growth conditions (exponential phase, stationary phase, and dormancy NRP1 and NRP2 phases induced by hypoxia), during biofilm formation, and in contact with macrophages and alveolar epithelial cells. We found that expression of tad/flp genes was significantly higher in the stationary phase than in exponential or NRP1 or NRP2 phases suggesting that the bacteria do not require type IV pili during dormancy. Elevated gene expression levels were recorded when the bacilli were in contact for 4 h with macrophages or epithelial cells, compared to mycobacteria propagated alone in the cultured medium. An antibody raised against a 12-mer peptide derived from the Flp pilin subunit detected the presence of Flp pili on intra- and extracellular bacteria infecting eukaryotic cells. Altogether, these are compelling data showing that the Flp pili genes are expressed during the interaction of Mtb with host cells and highlight a role for Flp pili in colonization and invasion of the host, subsequently promoting bacterial survival during dormancy.

Uso terapéutico del método de restricción de flujo sanguíneo para la mejora de la fuerza muscular. Una revisión sistemática / Therapeutic use of the blood flow restriction training on muscle strength. A systematic review

Introducción: El método de restricción de flujo sanguíneo implica la ejecución de ejercicio de resistencia de baja intensidad combinado con restricción de flujo sanguíneo proporcionada por un manguito inflable o un torniquete colocado proximal al músculo. El objetivo de este trabajo es analizar la bibliografía científica actual para conocer el uso del método de restricción de flujo sanguíneo para la mejora de la fuerza muscular. Material y métodos: Se llevó a cabo una búsqueda bibliográfica en las bases de datos científicas PubMed, Medline, Cinhal, Sport Discus, Scopus, Web of Science y PEDro. Los descriptores empleados fueron: «Physical Therapy Modalities», «Physical Therapy», «Rehabilitation», «Muscle Strength», «Blood Flow Restriction Training» y «Blood Flow Restriction». Se incluyeron ensayos clínicos aleatorizados publicados en los últimos 5 años. Resultados: Se analizaron 13 artículos que fueron agrupados en tres tipos de población de estudio sobre los que se analiza la restricción del flujo sanguíneo: sujetos con patología de rodilla, en personas mayores y en personas sin patología. Se observaron mejoras significativas para la fuerza muscular con la aplicación de restricción de flujo sanguíneo en los tres grupos de estudio. Conclusión: La restricción de flujo sanguíneo ha demostrado ser un método válido en fisioterapia para la mejora de la fuerza muscular en sujetos con patología de rodilla, en personas mayores y en personas sanas. Se puede considerar un método eficaz para ganar fuerza muscular y a su vez ser una alternativa a los programas de mejora de la fuerza convencionales. (AU)

Introduction: Restriction blood flow training implies low intensity endurance exercises combined with blood flow restriction by an inflatable cuff or tourniquet placed proximal to the muscle. The aim of this study is to analyze the scientific literature about the use of restriction blood flow training to improve muscle strength. Material and methods: A systematic search was carried out in Pubmed, Medline, Cinahl, Sport Discus, Scopus, Web Of Science and PEDro. The descriptors used were «Physical Therapy Modalities», «Physical Therapy», «Rehabilitation», «Muscle Strength», «Blood Flow Restriction Training» and «Blood Flow Restriction». Randomized clinical trials published in the last 5years were included. Results: Thirteen articles were studied in this systematic review, grouped into three types of study population on which blood flow restriction was analyzed: subjects with knee pathology, elderly people and people without pathology. Significant improvements in muscle strength were observed with the application of blood flow restriction in all three study groups. Conclusion: Blood flow restriction has proven to be a valid method in physical therapy for the improvement of muscle strength in subjects with knee pathology, in elderly people and in healthy people. It can be considered an effective method to gain muscle strength and at the same time be an alternative to conventional strength improvement programs. (AU)

Therapeutic Exercise Combined or not with Pelvic Floor Muscle Training for Urinary Incontinence

Introduction: The most used physiotherapy treatment is the pelvic floor muscle training. Other factors are involved in the control of urination, such as the management of abdominal pressure and the activity of the muscles and fascia of the lumbopelvic region and this could be trained through generalized therapeutic exercise, which is defined as an intervention aimed at restoring musculoskeletal, cardiopulmonary and neurological function. The objective of this review is to evaluate the effects of therapeutic exercise, combined or not with analytical training of the pelvic floor muscles, on urinary incontinence in women over 18 years of age, by reviewing the scientific literature. Objective: To assess the effects of therapy exercise other than or combined with pelvic floor muscle training on urinary incontinence in women over 18 years. Material and Methods: An article research was done between 11th January and 7th February, 2021 on the following databases: Pubmed, Medline, Cinahl, Web Of Science, Sport Discus and PEDro using the search terms “Urinary Incontinence” and “Exercise Therapy”. Results: An average of 245 results were obtained, of which 10 were selected after applying the eligibility criteria. The interventions of the analyzed articles are divided into two groups. First, a group where muscles of the abdominal-pelvic-perineal region are worked (hypopressives, yoga and strength of the abdominal muscles, resisted hip rotation...). Secondly, another group where muscles in general are worked (weight training, flexibility, balance and toning and cardiovascular training). Conclusion: Urinary incontinence treated with therapy exercise other than the pelvic floor muscles training, or combined with it, suggest improvements in symptoms (AU)

Introducción: El tratamiento de fisioterapia más usado para la incontinencia es el ejercicio terapéutico mediante el entrenamiento específico de la musculatura del suelopélvico. En el control de la micción intervienen otros factores como la gestión de la presión abdominal y la actividadde los músculos y la fascia de la región lumbopélvica y estose podría entrenar mediante el ejercicio terapéutico generalizado, el cual se define como una intervención destinadaa restaurar la función musculoesquelética, cardiopulmonary neurológica. El objetivo de esta revisión es evaluar losefectos del ejercicio terapéutico, combinado o no con el entrenamiento analítico de la musculatura de suelo pélvico,sobre la incontinencia urinaria en mujeres mayores de 18años, mediante la revisión de la bibliografía científica.Material y Métodos: Se realizó una búsqueda deartículos entre el 11 de enero y el 7 de febrero del 2021en las bases de datos: Pubmed, Medline, Cinahl, Web OfScience, Sport Discus y PEDro empleando los términos debúsqueda “Urinary Incontinence” y “Exercise Therapy”.Resultados: Se obtuvieron un total de 245 resultados, de los cuales 10 fueron seleccionados tras aplicar loscriterios de elegibilidad. Las intervenciones de los artículos analizados se dividen en dos grupos, aquellos que trabajan musculatura de la región abdomino-pelvi-perineal(hipopresivos, yoga y fuerza de la musculatura abdominal,rotación de cadera resistida…) y otro grupo donde se realizaun trabajo generalizado de la musculatura (entrenamientocon pesas, flexibilidad, equilibrio y tonificación y entrenamiento cardiovascular).Conclusión: La incontinencia urinaria tratada conejercicio terapéutico distinto al entrenamiento de la musculatura del suelo pélvico, o combinado con él, parece obtenermejoras en la sintomatología (AU)
