RESUMEN

Introducción. El intestino primitivo rota durante la vida embrionaria. Cuando ocurre de forma inadecuada aparece la malrotación intestinal que puede llevar a la obstrucción o al vólvulo del intestino medio. La incidencia disminuye con el aumento de la edad. La malrotación intestinal es una de las principales causas de complicaciones del tracto gastrointestinal en la edad pediátrica. Métodos. Estudio retrospectivo, observacional, transversal y analítico, de la experiencia durante 10 años en pacientes menores de 15 años con diagnóstico de malrotación intestinal, tratados en el Hospital Infantil de San Vicente Fundación, en Medellín, Colombia. Se buscó la asociación entre variables demográficas, clínicas e imagenológicas con los desenlaces. Resultados. Se obtuvieron 58 pacientes con malrotación intestinal, 65 % menores de 1 año. En 29,3 % de los pacientes se hizo el diagnóstico con la presentación clínica; los síntomas predominantes fueron distensión abdominal y emesis. En el 24,1 % se confirmó el diagnóstico con imágenes. Las variables con una diferencia estadísticamente significativa a favor de encontrar una malrotación complicada fueron choque séptico (OR=11,7), síndrome de respuesta inflamatoria sistémica (OR=8,4) y deshidratación (OR=5,18). Conclusiones. La malrotación intestinal tiene complicaciones como perforación, peritonitis, vólvulo e intestino corto. El vólvulo se acompaña de shock y sepsis, con mortalidad hasta del 50 %. Las imágenes diagnósticas son una ayuda, pero no se puede basar la conducta médica en estas porque ninguna imagen garantiza el diagnóstico definitivo. Los signos de alarma son poco específicos. En menores de un año con emesis, distensión y dolor abdominal se debe sospechar malrotación intestinal.


Introduction. The primitive intestine rotates during embryonic life. When it occurs inappropriately, intestinal malrotation appears, which can lead to obstruction or midgut volvulus. The incidence decreases when age increases. Intestinal malrotation is one of the main causes of complications of the gastrointestinal tract in pediatric age. Method. Retrospective, observational, cross-sectional and analytical study of the experience over 10 years in patients under 15 years of age with a diagnosis of intestinal malrotation, treated at Hospital Infantil of San Vicente Fundación, in Medellín, Colombia. The association between demographic, clinical and imaging variables with the outcomes was sought. Results. There were 58 patients with intestinal malrotation, 65% under one year of age. In 29.3% of patients, intestinal malrotation was diagnosed clinically. The predominant symptoms were abdominal distension and emesis. In 24.1% the diagnosis was confirmed with imaging. The variables with a statistically significant difference in favor of finding a complicated malrotation were septic shock (OR=11.7), systemic inflammatory response syndrome (OR-8.4), and dehydration (OR=5.18). Conclusions. Malrotation has complications such as perforation, peritonitis, volvulus, and short bowel. Volvulus is accompanied by shock and sepsis, with mortality of up to 50%. Diagnostic images are helpful, but medical conduct cannot be based on them because no image guarantees a definitive diagnosis. The warning signs are not very specific. In children under one year of age with emesis, distension and abdominal pain, intestinal malrotation should be suspected.

RESUMEN

Introducción. La colocación de endoprótesis biliares es cada día más frecuente por ser actualmente una de las mejores opciones para el tratamiento de patologías de la vía biliar. La migración de las endoprótesis es una de las complicaciones que puede ocurrir en hasta un 10,8 % de los pacientes, pero en muy raras ocasiones llegan a causar una perforación intestinal. Caso clínico. Se trata de una paciente de 61 años, a quien cinco años atrás se le realizó una colangiopancreatografía retrógrada endoscópica por coledocolitiasis. Consultó por presentar dolor abdominal, y al examen físico se encontraron abdomen agudo y plastrón en fosa ilíaca izquierda a la palpación. La tomografía computarizada informó un cuerpo extraño a nivel del colon descendente, con perforación del mismo. Se realizó laparotomía exploratoria y colostomía por perforación del colon sigmoides secundaria a prótesis biliar migrada. Resultados. La paciente evolucionó favorablemente y a los seis meses se realizó el cierre de la colostomía, sin complicaciones. Conclusión. Los pacientes a quienes se les colocan prótesis biliares requieren un seguimiento adecuado para evitar complicaciones que, aunque raras, pueden ocurrir, como la migración intestinal con perforación. El tratamiento de dichas complicaciones se hace por vía endoscópica, laparoscópica o laparotomía en caso de complicación severa.


Introduction. Endoscopic placement of biliary stents is becoming more common every day, as it is currently one of the best options for the treatment of bile duct pathologies. One of the complications that can occur is the migration of the endoprostheses in up to 10.8% of patients, which in very rare cases can cause intestinal perforation. Clinical case. This is a 61-year-old female patient, who underwent endoscopic retrograde cholangiopancreatography five years ago for choledocholithiasis. She consulted due to abdominal pain, with a physical examination that upon palpation documented an acute abdomen and a palpable plastron in the left iliac fossa. The computed tomography revealed a foreign body at the level of the descending colon, with perforation. Exploratory laparotomy and colostomy were performed due to perforation of the sigmoid colon secondary to migrated biliary prosthesis. Results. The patient progressed favorably and six months later the colostomy was closed without complications. Conclusions. Patients who receive biliary stents require adequate follow-up to avoid complications that, although rare, may occur, such as intestinal migration with intestinal perforation. The treatment of these complications can be endoscopic, laparoscopic or laparotomy in case of severe complication.

RESUMEN

Abstract Background To illustrate how (standardised) effect sizes (ES) vary based on calculation method and to provide considerations for improved reporting. Methods Data from three trials of tanezumab in subjects with osteoarthritis were analyzed. ES of tanezumab versus comparator for WOMAC Pain (outcome) was defined as least squares difference between means (mixed model for repeated measures analysis) divided by a pooled standard deviation (SD) of outcome scores. Three approaches to computing the SD were evaluated: Baseline (the pooled SD of WOMAC Pain values at baseline [pooled across treatments]); Endpoint (the pooled SD of these values at the time primary endpoints were assessed); and Median (the median pooled SD of these values based on the pooled SDs across available timepoints). Bootstrap analyses were used to compute 95% confidence intervals (CI). Results ES (95% CI) of tanezumab 2.5 mg based on Baseline, Endpoint, and Median SDs in one study were - 0.416 (- 0.796, - 0.060), - 0.195 (- 0.371, - 0.028), and - 0.196 (- 0.373, - 0.028), respectively; negative values indicate pain improvement. This pattern of ES differences (largest with Baseline SD, smallest with Endpoint SD, Median SD similar to Endpoint SD) was consistent across all studies and doses of tanezumab. Conclusion Differences in ES affect interpretation of treatment effect. Therefore, we advocate clearly reporting individual elements of ES in addition to its overall calculation. This is particularly important when ES estimates are used to determine sample sizes for clinical trials, as larger ES will lead to smaller sample sizes and potentially underpowered studies. Trial Registration Clinicaltrials.gov NCT02697773, NCT02709486, and NCT02528188.

RESUMEN

Resumen OBJETIVO: Identificar los principales hallazgos histopatológicos benignos y determinar la tasa de falsos positivos que suelen causar conflicto al categorizar las mastografías en el sistema BI-RADS por su aspecto, que puede simular un proceso maligno. MATERIALES Y MÉTODOS: Estudio de cohorte, retrospectivo, efectuado en pacientes atendidas en la Unidad Médica de Alta Especialidad 4 Luis Castelazo Ayala (2019-2023) con reporte mastográfico alterado o sospecha clínica de malignidad. Para el análisis estadístico se utilizó el programa JASP 2.0 y χ2 para la diferencia de proporciones entre grupos. RESULTADOS: De un grupo de 11,481 pacientes, se reportaron 1643 mastografías alteradas: 444 con reportes falsos positivos, 23 pacientes con sospecha clínica y exclusión de 16 que no cumplieron con los criterios de inclusión establecidos. La muestra poblacional estudiada fue de 451 pacientes. La mayoría permaneció asintomática al momento del estudio (42.1%). El hallazgo histopatológico benigno con mayor prevalencia fue el fibroadenoma y su síntoma más relevante el nódulo palpable. La tasa de falsos positivos fue de 4.3%. CONCLUSIONES: En la actualidad, gracias a la implementación de programas de tamizaje es posible establecer diagnósticos de cáncer de mama en etapas tempranas, aunque con la desventaja que el reporte puede resultar falso positivo y ello dar lugar a incremento de la morbilidad y sobretratamiento. Los estándares internacionales indican que estos no deben sobrepasar el 10%.


Abstract OBJECTIVE: To identify the main benign histopathological findings that often cause conflict when categorizing mastographies in the BI-RADS system due to their appearance, which may simulate a malignant process and false positive rate. MATERIALS AND METHODS: Retrospective cohort study carried out in patients attended at the Unidad Médica de Alta Especialidad 4 Luis Castelazo Ayala (2019-2023) with an altered mastographic report or clinical suspicion of malignancy. For statistical analysis we used the JASP 2.0 programme and χ2 for the difference in proportions between groups. RESULTS: From a group of 11,481 patients, 1,643 altered mastograms were reported: 444 with false positive reports, 23 patients with clinical suspicion and exclusion of 16 who did not meet the established inclusion criteria. The population sample studied was 451 patients. The majority remained asymptomatic at the time of the study (42.1%). The most prevalent benign histopathological finding was fibroadenoma and the most relevant symptom was a palpable nodule. The false positive rate was 4.3%. CONCLUSIONS: Currently, thanks to the implementation of screening programmes it is possible to establish breast cancer diagnoses in early stages, although with the disadvantage that the report may be false positive and this may lead to increased morbidity and overtreatment. International standards indicate that these should not exceed 10%.

RESUMEN

Introducción: la inmunosenescencia está asociada con un mayor riesgo de desarrollo de cáncer. Dentro de las hemopatías malignas que afectan a este grupo de edad, está la leucemia linfoide crónica (LLC), caracterizada por trastornos en la inmunidad adaptativa que incluye las subpoblaciones de linfocitos T. Objetivo: Determinar la frecuencia de las subpoblaciones de linfocitos T en los pacientes adultos mayores con leucemia linfoide crónica evaluados en el Instituto de Hematología e Inmunología de Cuba. Métodos: Se realizó un estudio transversal en 30 adultos mayores con leucemia linfoide crónica. Se cuantificaron los linfocitos TCD3+CD4+ y TCD3+CD8+ en sangre periférica por citometría de flujo. Para la lectura y el análisis de los datos se empleó un citómetro de flujo Beckman Coulter Gallios. Se utilizaron los valores porcentuales, la media y la desviación estándar. Se consideró estadísticamente significativo si p≤0.05. Resultados: Hubo un predominio de hombres que representaron el 56,7 por ciento y del grupo de 70-79 años de edad. No se reportó ningún adulto mayor con LLC con valores altos ni normales de linfocitos TCD3+CD4+. Predominaron los hombres con valores bajos porcentuales de linfocitos TCD3+CD4+, TCD3+CD8+ e inversión del índice CD4/CD8 en relación con las mujeres. Conclusiones: Los adultos mayores con LLC presentan alteraciones en el número de las subpoblaciones de linfocitos T. La acción de estas células en relación al crecimiento de células B malignas aún es desconocido y resulta importante determinar si esto puede reflejar un intento de evasión de las células tumorales al control inmunológico(AU)


Introduction: Immunosenescence is associated with an increased risk of cancer development. Among the malignant hemopathies that affect this age group, it is chronic lymphoid leukemia (CLL), characterized by disorders in adaptive immunity, which include subpopulations of T lymphocytes. Objective: To determine frequency of T lymphocyte subpopulations in older adult patients with chronic lymphoid leukemia evaluated at the Institute of Hematology and Immunology of Cuba. Methods: A cross-sectional study was conducted in 30 older adults with chronic lymphoid leukemia. TCD3+CD4+ and TCD3+CD8+ lymphocytes were quantified in peripheral blood by flow cytometry. A Beckman Coulter Gallios flow cytometer was used to read and analyze the data. The percentage values, the mean and the standard deviation were used. It was considered statistically significant if p≤0.05. Results: There was a predominance of men who represented 56.7 percent and the age group of 70-79 years. No older adults with CLL with high or normal values of TCD3+CD4+ lymphocytes were reported. Men predominated with low percentage values of TCD3+CD4+, TCD3+CD8+ lymphocytes and inversion of the CD4/CD8 ratio in relation to women. Conclusions: Older adult with CLL present alterations in the number of T lymphocyte subpopulations. The role of these cells in relation to the growth of malignant B cells it is unknown and it turns out important to determine if this may reflect an attempt to evade tumor cells from immune control(AU)

RESUMEN

The burden of epilepsy in developing countries made medicinal plants like Xylopia aethiopica fruit; Khaya grandifoliola, Alstonia boonei etc an alternative source in epilepsy management in the south-western part of Nigeria. The aim of the study was to provide pharmacological rationale for the ethnomedicinal use of the plants in epilepsy management. The oral medial lethal dose of methanol stem bark extracts of Alstonia boonei (MEAB) and Khaya grandifoliola (MEKG) and methanol fruit extract of Xylopia aethiopica (MEXAF) were done in accordance with the Organization for Economic Cooperation Development guideline. Quantitative and qualitative phytochemical profiling of the extracts was done. Anticonvulsant screening was carried out on the extracts (doses: 75, 150 and 300 mg/kg) using the pentylenetetrazole (PTZ)-induced seizure and maximum electroshock tests (MEST). Results showed that the MEXAF has the highest amount of phytochemicals except for saponins in MEKG; and MEAB with the least amount (but higher alkaloid) than MEKG. The TLC showed different bands of spots of the extracts. In the PTZ test, MEXAF showed 100 % protection against mortality at 300 mg/kg; MEAB with 66.67 % protection at 75 mg/kg and MEKG 0 % protection. MEAB, MEKG and MEXAF nonsignificantly increased the onset of seizure and latency to death. In the MEST, MEXAF, MEKG and MEAB at 75 mg/kg protected 50, 33.3 and 16.67% of the animals against tonic hind limb extension respectively and nonsignificantly (p˃0.05) decreased the recovery time at a dose of 75 mg/kg. It was concluded that the extracts possess anticonvulsant activities hence, the pharmacological credence for the ethnomedicinal use of these plants in treating epilepsy.

RESUMEN

According to the World Health Organizations (WHO) family medicine forms the bedrock upon for accessible, affordable and equitable healthcare for any country. The need for family doctors is more acute for low income countries like The Gambia. More so that The Gambian health infrastructure is suboptimal and appropriate health personnel is low. This is worsened by brain drain leading to poor health indices. Despite these challenges and more, the department of Family Medicine was accredited for training in the Gambia with improved infrastructure (at the training centre), with 7 residents. Though there are still challenges there are also opportunities and strengths. There is therefore hope that the right personnel will be produced for an improved Gambian health system.

RESUMEN

Abstract Osteomyelitis is defined as the inflammation of the either medullary, cortical, or cancellous bone, including nerves and blood vessels, causing necrosis and bone sequestrum formation; this condition has become a rare pathology, and odontogenic infections are considered the most frequent causal factor. This case shows a patient with bi-maxillary osteomyelitis caused by Actinomyces spp, which was worsened for severe COVID-19 infection. Patient was submitted at surgery as, amplified total bilateral maxillectomy through the surgical technique Weber-Fergusson, and prolonged use of combination of antibiotics, achieved a good recovery. Two years later follow- up, the patient no show imaging or clinical evidence of the infection of osteomyelitis. The present case shows an interesting relationship between a rare infection and its association with COVID-19.


Resumen La osteomielitis se define como la inflamación del hueso medular, cortical o esponjoso, incluyendo nervios y vasos sanguíneos, causando necrosis y formación de secuestro óseo; esta condición es una patología rara, y las infecciones odontogénicas son consideradas como el factor causal más frecuente. En este caso, se muestra un paciente con osteomielitis bi-maxilar causada por Actinomyces spp, la cual empeoró por la infección de COVID-19 severo. El paciente fue sometido a una cirugía, maxilectomía bilateral total amplificada, a través de la técnica quirúrgica de Weber- Fergusson, y el uso prolongado de una combinación de antibióticos, logrando una buena recuperación. A los 2 años de seguimiento, el paciente no mostró evidencia clínica o imagenológica de la infección de osteomielitis. El presente caso muestra una interesante relación entre una infección rara y su asociación con COVID-19.

RESUMEN

Abstract Introduction: Tlaloc hildebrandi is a freshwater killifish, endemic to Southern Mexico and under threat of extinction; the knowledge of the trophic morphology and diet is needed by conservation managers. Objective: To analyse and describe the anatomy of the visceral skeleton, visceral musculature, digestive tract and its adjoining glands of T. hildebrandi; as well as its diet. Methods: We performed the trophic anatomy on 20 adult specimens of both sexes, through manual dissection; as well as gut content analysis in 60 individuals to describe the diet. Results: As notable characters of the visceral skeleton of T. hildebrandi we found the posterior notch of the premaxillary, the presence of the "coronoid cartilage", the tricuspid shape of the gill rakers of the first branchial arch, and the presence of the coronomeckelian bone; some outstanding characters of the visceral musculature are the origin of the retractor dorsalis muscle from the first four vertebral centra, and the division of the pharyngoclavicularis externus muscle into two sections. The notable characters of the digestive tube are the absence of stomach and pyloric caeca, and the presence of the "intestinal valve". Insects (IVI = 66.6 %) and ostracods (13 % IVI) were the dominant prey items of the Tlaloc hildebrandi diet; larvae and adults of the family Chironomidae were the most dominant insects in the diet (53 % IVI). Conclusions: The organization of the digestive system of T. hildebrandi corresponds to the general morphologic pattern of the Cyprinodontiformes; however, we register as new information for these fish, the presence of the "coronoid cartilage" and the "intestinal valve". The structures of the trophic morphology and the components of the diet, confirms us that T. hildebrandi is a carnivorous-insectivorous fish.


Resumen Introducción: Tlaloc hildebrandi es un killi de agua dulce, endémico del sur de México y bajo amenaza de extinción; el conocimiento de la morfología trófica y la dieta son necesarios para los administradores de la conservación. Objetivo: Analizar y describir la anatomía del esqueleto visceral, la musculatura visceral, el tracto digestivo y las glándulas adyacentes de T. hildebrandi; así como los componentes de su dieta. Métodos: Mediante la técnica del descarnado manual, realizamos la descripción de la anatomía trófica en 20 especímenes adultos de ambos sexos, y el análisis del contenido estomacal en 60 individuos para describir la dieta. Resultados: Como caracteres sobresalientes del esqueleto visceral de T. hildebrandi está la escotadura posterior del premaxilar, la presencia del "cartílago coronoides", la forma tricúspide de las branquiespinas del primer arco branquial y la presencia del hueso coronomeckeliano; como caracteres de la musculatura visceral sobresalen el origen del músculo retractor dorsalis de los cuatro primeros centros vertebrales, y la división del músculo pharyngoclavicularis externus en dos secciones. Los caracteres notables del tubo digestivo son la ausencia de estómago y de ciegos pilóricos y la presencia de la "válvula intestinal". Los insectos (IVI = 66.6 %) y ostrácodos (13 % IVI) fueron los componentes dominantes de la dieta de T. hildebrandi; particularmente las larvas y adultos de la familia Chironomidae fueron los insectos más abundantes en la dieta (53 % IVI). Conclusiones: La organización del sistema digestivo de T. hildebrandi corresponde al patrón morfológico general de los Cyprinodontiformes, sin embargo, se registra como nueva información para estos peces, la presencia del cartílago coronoides y la válvula intestinal. Las estructuras de la morfología trófica y los componentes de la dieta nos confirman que T. hildebrandi es un pez carnívoro-insectívoro.

RESUMEN

Abstract Introduction : Lower limb peripheral artery disease (PAD) presents high morbidity and mortality. Women represent a small subgroup in different studies, with scarce evidence regarding the prognosis of this gender on PAD. The aim of the present work was to determine the prognostic impact of female gender on lower limb PAD revascularization. Methods : This was a retrospective, single-center study, including patients undergoing symptomatic lower limb PAD revascularization. Results : Among a total of 309 patients included in the study, 109 belonged to the female gender (35%). Women were older and presented lower prevalence of cardiovascular risk factors compared with the male gender. All-cause mortality (22% vs. 12%, p = 0.02) and re-hospitalizations for chronic limb-threatening ischemia (18% vs. 10%, p = 0.04) rates were significantly higher in women. In a multivariate regression model, female gender was independently associated with all-cause mortality (OR 2.19 [95% CI: 1.06-4.51], p = 0.03). The time-to-event showed that women exhibited 93% more risk of suffering death than men, after adjusting for clinically relevant variables (HR 1.93 [95% CI: 1.04-3.56], p = 0.04). Discussion : Women with symptomatic PAD revascu larization presented worse prognosis than men in terms of all-cause mortality and re-hospitalizations for chronic limb-threatening ischemia rates. Therefore, it is essen tial to achieve an adequate control of cardiovascular risk factors, as well as to optimize medical treatment in female patients.


Resumen Introducción : La enfermedad arterial de miembros inferiores (EAMI) presenta elevada morbimortalidad. Las mujeres constituyen un subgrupo minoritario en distin tos estudios, con escasa evidencia acerca del pronóstico por género en EAMI. Nuestro objetivo fue determinar el impacto pronóstico del género femenino en la revascu larización de EAMI. Métodos : Estudio de cohorte retrospectivo y unicén trico, que incluyó pacientes con EAMI sintomática y revascularizada. Resultados : Se incluyeron 309 pacientes, de los cuales 109 (35%) eran mujeres. Las mujeres fueron más añosas y presentaron menor prevalencia de factores de riesgo cardiovascular en comparación a los hombres. Las tasas de mortalidad por todas las causas (22% vs. 12%, p = 0.02) y de hospitalizaciones por isquemia crítica (18% vs. 10%, p 0.04) fueron significativamente mayores en mujeres. En el modelo de regresión multivariado, el sexo femenino se asoció de forma independiente con mortalidad por todas las causas (OR 2.19 [IC 95%: 1.06-4.51], p = 0.03). En el análisis de tiempo al evento, las mujeres tuvieron 93% más riesgo de morir que los hombres, luego de ajustar por variables clínicamente relevantes (HR 1.93 [IC 95%: 1.04-3.56], p = 0.04). Discusión : Las mujeres con EAMI sintomática y re vascularizada presentaron un peor pronóstico en com paración a los hombres en términos de tasas de mor talidad por todas las causas y de hospitalizaciones por isquemia crítica de miembros inferiores. Por lo tanto, es fundamental lograr un adecuado control de factores de riesgo cardiovascular, como así también, optimizar el tratamiento médico en el género femenino.

RESUMEN

Resumen Antecedentes: Las infecciones de transmisión sexual son un problema de salud pública mundial. El análisis rutinario incluye solo pruebas microbiológicas y serológicas para el diagnóstico de patógenos. Los microorganismos atípicos como Chlamydia trachomatis y micoplasmas no son identificados debido a los requerimientos. Además, no es incluida Gardnerella vaginalis, aunque se asocia a la vaginosis bacteriana. Objetivo: Desarrollar una PCR múltiplex para el diagnóstico de C. trachomatis, micoplasmas y G. vaginalis. Método: Se estandarizó la PCR múltiplex utilizando oligonucleótidos para C. trachomatis (gen ompA, orf6 plasmídico), Mycoplasma/Ureaplasma y G. vaginalis (genes rRNA16s). Resultados: Se estandarizaron pruebas de PCR múltiplex para los microorganismos estudiados, optimizándose las concentraciones y condiciones de las reacciones múltiplex. Se obtuvieron PCR dúplex para C. trachomatis (ompA, orf6), Chlamydia/Gardnerella y Chlamydia/micoplasmas y tríplex para Chlamydia/Mycoplasma/Ureaplasma. También un cuádruplex para Chlamydia/Mycoplasma/Ureaplasma/Gardnerella. Los resultados fueron verificados por PCR e hibridación automática (HybriSpot 12) y análisis in silico. Conclusión: Se desarrollaron pruebas de PCR múltiplex con una alta sensibilidad y especificidad para la identificación de C. trachomatis, micoplasmas y G. vaginalis.


Abstract Background: Sexually transmitted infections are a global public health problem. Routine analysis includes microbiological and serological tests for the diagnosis of pathogens. Atypical microorganisms such as Chlamydia trachomatis and mycoplasmas are not determined due to the requirements for their identification. Furthermore, Gardnerella vaginalis is not included despite being associated with bacterial vaginosis. Objective: To develop a multiplex PCR to diagnose Chlamydia, mycoplasmas, and Gardnerella. Method: Standardization of multiplex PCR tests was carried out using oligonucleotides for the identification of Chlamydia (ompA gene, plasmid orf6), Mycoplasma/Ureaplasma and Gardnerella (rRNA16s genes). Results: Multiplex PCR tests were standardized for the microorganisms studied, optimizing the concentrations and conditions of the multiplex reactions. Duplex PCR was obtained for Chlamydia (ompA, orf6), Chlamydia/Gardnerella, and Chlamydia/mycoplasmas, and triplex PCR for Chlamydia/mycoplasmas. Also, a quadruplex for Chlamydia, Mycoplasma/Ureaplasma and Gardnerella. PCR and automatic hybridization verified the results obtained (HybriSpot 12) and in silico analysis. Conclusion: Multiplex PCR tests with high sensitivity and specificity were developed to identify C. trachomatis, mycoplasmas, and G. vaginalis.

RESUMEN

A hipertensão arterial sistêmica, principal fator de risco para as doenças cardiovasculares, é considerada a maior causa de mortes prematuras ao redor do mundo. Pacientes com baixa adesão ao tratamento apresentam maior risco de complicações, hospitalizações e morte prematura, além de aumentar a carga nos sistemas de saúde, onerando as economias nacionais. No Brasil, grande parte dos pacientes ainda apresenta um controle ruim dos fatores de risco cardiovascular, não atingindo as recomendações das principais diretrizes nacionais e internacionais. Com o intuito de trazer soluções para a falta de adesão, a tecnologia se torna uma importante aliada no automonitoramento e regularidade de tratamento. Aplicativos de automonitoramento com programas de gamificação são tecnologias emergentes, e seus resultados têm encorajado sua adoção porque estimulam os pacientes a se comprometerem com mudanças comportamentais e de estilo de vida. Elfie é uma solução digital inovadora e gratuita, validada pela Sociedade Brasileira de Cardiologia, pela Sociedade Brasileira de Diabetes e pela Associação Nacional de Atenção ao Diabetes, que, além de permitir que os usuários monitorem a sua condição física, também possam aprendam sobre sua saúde e recebam suporte personalizado por meio de um smartphone ou tablet, além de manter um banco de dados eletrônico para posterior consulta do próprio paciente e dos prestadores de cuidado à saúde, como médicos e nutricionistas. Os profissionais de saúde devem ser encorajados a discutir a utilidade desse tipo de ferramenta com seus pacientes, oferecendo, assim, a oportunidade de melhores desfechos clínicos e, consequentemente, reduzindo hospitalizações, mortalidade e custos em saúde.


Systemic Arterial Hypertension, the main risk factor for cardiovascular disease, is considered the greatest cause of premature deaths worldwide. Patients with low adherence to treatment are more susceptible for complications, hospitalizations, and premature death. In addition, there is an increasing burden on health systems and national economies for cardiovascular disease purposes. In Brazil, a large number of patients still have poor control of the risk factors, not reaching the recommendations of national and international guidelines. In order to attend with solutions, technology becomes an important ally in self-monitoring and regularity of treatment. Self-monitoring apps with gamification programs are emerging technologies which the results have encouraged their adoption because they inspire patients to commit with behavioral and lifestyle changes. Elfie is a novel free digital solution, endorsed by the Brazilian Society of Cardiology, the Brazilian Society of Diabetes and the National Diabetes Care Association. It allows the users to monitor and learn about their health and to receive personalized support through a smartphone or tablet. It also has a database that can be later accessed by the patient or healthcare providers, such as physicians and nutritionists. Healthcare professionals should be encouraged to discuss the advantages of these tools with their patients to offer an opportunity for better clinical outcomes and, consequently reduce hospitalizations, mortality and healthcare costs

RESUMEN

Resumen Objetivo: Analizar los resultados de la técnica quirúrgica de colocación de clavillos Kirschner forma lateral versus cruzada en el manejo de las fracturas supracondíleas de húmero en pacientes pediátricos. Metodología: Se captaron a todos los pacientes con fractura supracondílea humeral en edad pediátrica que requirieron intervención quirúrgica, y posteriormente fueron evaluados a las 24 horas y 6 meses posterior al tratamiento quirúrgico para observar y comparar las diferencias entre cada técnica quirúrgica utilizada, tomando en cuenta las complicaciones agudas y tardías que se presentaron mediante un análisis con la prueba de Mann-Whitney. Resultados: Para el presente estudios se evaluaron 44 pacientes pediátricos de los cuales 70% eran hombres y 30% mujeres, en quienes se presentaron complicaciones nerviosas y angulares sin importancia significativa alguna con el sexo y edades de los pacientes, siendo la afección del nervio cubital la de mayor frecuencia con 33% en la colocación de forma cruzada. Al realizar la comparativa con discriminación de variables se obtiene que la colocación de forma lateral presenta menos complicaciones posquirúrgicas tempranas y tardías y que tales no se deben al azar. Limitaciones o implicaciones: En el presente estudio no se incluyó el tipo de daño mecánico que provoca este tipo de fractura, ni se consideró el ángulo de Baumann. Otra limitación inherente en la población pediátrica es la habilidad del explorador para detectar un déficit neurológico, especialmente en pacientes de edad temprana dado a que los reportes de una exploración física siempre son subjetivos. Además, dada la limitación en cuanto a los detalles del mecanismo específico de daño, se puede subestimar el número de daños provocados por mecanismos de alta energía. Originalidad y valor: Su importancia radica en que ambas técnicas quirúrgicas fueron realizadas por los mismos cirujanos y que se trata de un estudio en población mexicana, siendo un aporte para la literatura de este país. Conclusión: Ambas técnicas quirúrgicas presentan resultados posquirúrgicos con casos de lesión nerviosa, deformidad angular, dolor y edema persistente, pero la que los presenta en menor frecuencia es la técnica de colocación de clavillos Kirschner en forma lateral, además de causar una significancia estadística en cuanto a la disminución de presentar cubito valgo en el seguimiento tardío de los pacientes.


Abstract: Objective: To analyze the results of the surgical technique placement of Kirschner pins lateral versus crossed in the management of supracondylar fractures of the humerus in pediatric patients. Methodology: All pediatric patients with humeral supracondylar fracture who required surgical intervention and were subsequently evaluated 24 hours and 6 months after surgical treatment to observe and compare the differences between each patient. surgical technique used. Taking into account the acute and late complications that occurred, through an analysis with the Mann-Whitney test. Results: For the present studies, 44 pediatric patients were evaluated, of whom 70% were men and 30% women, in whom nerve and angular complications presented without any significant importance with the sex and age of the patients, with ulnar nerve involvement being the most frequent with 33% in cross placement. When carrying out the comparison with discrimination of variables, it is obtained that the placement laterally presents fewer early and late post-surgical complications and that such are not due to chance. Or the present study, it is considered that a placement of Kirschner pins laterally regardless of the member, age, gender or classification; leads to better post-surgical results. Limitations or implications: In the present study, the type of mechanical damage that causes this type of fracture was not included, nor was the Baumann angle considered. Another limitation inherent in the pediatric population is the ability of the examiner to detect a neurological deficit, especially in young patients since reports of a physical examination are always subjective. Furthermore, given the limited details of the specific damage mechanism, the number of damages caused by high-energy mechanisms may be underestimated. Originality or value: Its importance lies in the fact that both surgical techniques were performed by the same surgeons and that it is a study in the mexican population, being a contribution to the literature of this country. Findings or conclusions: Both surgical techniques present post-surgical results with cases of nerve injury, angular deformity, pain and persistent edema, but the one that presents them less frequently in the technique of placement of Kirschner pins laterally, in addition to causing statistical significance in terms of the decrease of presenting cubitus valgus in the late follow-up of the patients.

RESUMEN

Renal cell carcinoma (RCC) is the most common subtype of adult renal tumors, and its detection rate in the early stages has been increased in the dawn of advanced imaging modalities. Nephrectomy is the mainstay of treatment; determination of tumor category and staging is the primary concern of oncopathologists. Non-neoplastic renal parenchyma is overlooked majority of times and thus misses the opportunity to detect concomitant medical renal diseases which also predict the renal outcome in the postoperative era. Although any kind of glomerular or extraglomerular pathology may be encountered, vascular changes in the form of arterionephrosclerosis are the commonest one. Here, we take the opportunity to report an unusual association of heavy chain deposition disease (HCDD) with clear cell subtypes of renal cell carcinoma in a 48-year-old male of Indian ethnicity.

RESUMEN

Abstract Background: Peripheral artery disease (PAD) frequently affects multiple segments of the limbs. Contradictory data have reported worse prognosis in aortoiliac lesions, nevertheless, diabetes and chronic limb ischemia frequently affects the infrapatellar territory. Our aim was to assess the impact of infrapatellar disease in cardiovascular outcomes. Methods: We performed a retrospective, observational cohort study at a university hospital in Argentina. Electronic health records were retrospectively reviewed including symptomatic PAD patients requiring revascularization. A multivariable regression model was performed to account for confounders. The primary endpoint was a composite of hospitalizations due to chronic limb threatening ischemia (CLTI) and major amputation events between infrapatellar and suprapatellar patients. Minor amputation events, all-cause death, myocardial infarction (MI), stroke, and major cardiovascular events (MACE) were secondary endpoints. Results: From January 2014 through July 2020, a total of 309 patients were included in the analysis. 151 patients had suprapatellar disease, and 158 had infrapatellar disease. The primary composite endpoint occurred in 35 patients (22.2%) in the infrapatellar patients and 18 patients (11.9%) in the suprapatellar patients (HR = 2.16; 95% confidence interval [CI] = [1.22-3.82]; p = 0.008). Both components of the primary outcomes occurred more frequently in infrapatellar patients. Minor amputation events were more prevalent in infrapatellar patients (HR = 5.09; 95% CI = [1.47-17.6]; p = 0.010). Death, MI, stroke, and MACE events were not different among groups (all p > 0.05). Conclusion: Infrapatellar disease was an independent factor for increased hospitalization of CLTI, major and minor amputations events, compared to suprapatellar disease in symptomatic revascularized PAD patients.


Resumen Objetivo: La enfermedad vascular periférica (EVP) afecta generalmente múltiples segmentos de los miembros. Existe información contradictoria con respecto al pronóstico de pacientes con enfermedad aortoilíaca, sin embargo, la diabetes y la enfermedad critica de miembros inferiores habitualmente afecta el territorio infrapatelar. Nuestro objetivo es determinar el impacto de la afectación infrapatelar en eventos cardiovasculares. Métodos: Estudio retrospectivo, observacional en un hospital universitario de Argentina. Se revisó la historia clínica electrónica de pacientes con EVP con requerimiento de revascularización. Se generó un modelo de regresión multivariado incluyendo variables clínicamente relevantes. El punto final primario fue un combinado de hospitalización por isquemia crítica y amputaciones mayores entre pacientes con afectación infrapatelar y suprapatelar. Amputaciones menores, muerte por todas las causas, infarto agudo de miocardio (IAM), accidente cerebrovascular (ACV) y un combinado de eventos cardiovasculares (MACE) fueron los puntos secundarios. Resultados: Se reclutó un total de 309 pacientes desde enero de 2014 hasta julio de 2020. 151 pacientes presentaron enfermedad suprapatelar y 158 infrapatelar. El punto final primario ocurrió en 35 pacientes (22.2%) en el grupo infrapatelar y en 18 pacientes (11.9%) en suprapatelares (HR 2.16; intervalo de confianza 95% [1.22-3.82]; p = 0.008). Ambos componentes ocurrieron con mayor frecuencia en pacientes con afectación infrapatelar. Los eventos de amputación menor fueron mas prevalentes en pacientes con afectación infrapatelar (HR 5.09; IC95% [1.47-17.6]; p = 0.010) La mortalidad por todas las causas, IAM, ACV y MACE no fueron diferentes entre los grupos (p > 0.05). Conclusión: La enfermedad infrapatelar fue un factor independiente para mayor riesgo de hospitalización por isquemia critica, amputación mayor y menor comparado con pacientes con afectación suprapatelar en EVP sintomática revascularizada.

RESUMEN

Abstract Introduction Degenerative changes in the otolithic organs have been theorized to be caused by the mechanical obstruction to endolymphatic flow, possibly resulting in endolymphatic hydrops (ELH). Otolin-1 is an otoconial matrix protein that crosses the blood labyrinth barrier and has been found in the serum of healthy and diseased patients. Objective To measure the serum levels of Otolin-1 in Meniere disease (MD) patients and compared them with the healthy individuals. Methods This pilot, cross-sectional study was performed at our tertiary care referral center to compare the serum Otolin-1 levels of healthy individuals with those of MD patients. The blood samples were obtained during patients' visit to the vertigo clinic following remission of an acute episode. The data was analyzed using the Stata/SE version 12.0 (StataCorp. College Station, TX, USA). Comparison between the serum Otolin-1 levels in the two groups was performed using the unpaired t-test. A p-value of 0.05 was considered to be statistically significant. Results The participants were divided into two groups, with 31 MD patients, and 30 age and gender-matched members of the control group. The serum levels of Otolin-1 in MD patients (247.6, ± 44.2 pg/ml) were not found to be significantly different from those of the control group (236.2, ± 43.5 pg/ml) (p = 0.31). Conclusion The current study reveals that the serum levels of Otolin-1 are not significantly different between the patients with MD in the interictal phase and the control group's healthy ones.

RESUMEN

(analítico) Durante los últimos años diversas investigaciones analizaron la asociación entre contexto y desarrollo infantil. Un problema central es si el ambiente influye en el desarrollo cognitivo. El contexto está compuesto por diferentes niveles que interactúan entre sí e influyen en las personas: el microsistema, mesosistema, exosistema y el macrosistema. El objetivo de esta revisión sistemática es indagar acerca de los factores que pertenecen al contexto y modularían el desarrollo infantil. A través de una búsqueda de artículos empíricos en revistas científicas indexadas, se seleccionaron 22 artículos, los cuales fueron analizados mediante la comparación de las variables: población, país, instrumento de evaluación, constructo evaluado, frecuencia de evaluación y resultados. Los resultados muestran que los factores ambientales pertenecientes a cada nivel analizado tienen la capacidad de modular el desarrollo infantil.


(analytical) Over the past few years, research has focused on the association between context and child development. One of the central problems addressed is whether a child's environment influences cognitive development. The context consists of different levels that interact with each other and influence people: the microsystem, mesosystem, exosystem and macrosystem. The goal of this systematic review is to investigate factors that form part of the context and affect child development. Twenty-two articles were selected through a search of empirical articles in indexed scientific journals. These were analyzed by comparing the variables used: population, country, evaluation instrument, evaluated construct, evaluation frequency and results. The results show that environmental factors belonging to each context level have the capacity to modulate child development.


(analítico) Nos últimos anos, a investigação analisou a parceria entre o contexto e o desenvolvimento infantil. Um dos problemas centrais é se o ambiente influencia no desenvolvimento cognitivo. O contexto é composto por diferentes níveis que interagem entre si e influenciam as pessoas: o microssistema, o mesosistema, o exosistema e o macrosistema. O objetivo desta revisão sistemática é indagar sobre os fatores que pertencem ao contexto e modular o desenvolvimento infantil. Através de uma pesquisa de artigos empíricos em revistas científicas indexadas, foram selecionados 22 artigos, os quais foram analisados mediante a comparação das variáveis: população, país, instrumento de avaliação, constructo avaliado, frequência de avaliação e resultados. Os resultados mostram que os fatores ambientais pertencentes a cada nível analisado têm a capacidade de modular o desenvolvimento infantil.

RESUMEN

Background & objectives: Scrub typhus is a rickettsial infection seen along the Asian-Pacific rim and imposes a considerable burden on affected people in low- and middle-income countries. The present study was aimed to determine the direct cost of hospitalization of scrub typhus and its trend over six years. Methods: This was a retrospective, observational, hospital based study of individuals admitted to the hospital, diagnosed with scrub typhus over six years, from January 2013 to December 2018. The potential out of pocket expenditure was evaluated. Results: A total of 198 patients were included in the study. The median cost of admission (adjusted to INR 2020) for the six years (2013 to 2018) was found to be ? 37,026 (US $ 490) [interquartile range (IQR) 22,996-64,992]. The median cost for patients admitted to the intensive care unit (ICU) was ? 128,046 (US $ 1695) (IQR 71,575-201,171), while the cost for patients admitted to the ward-alone was ? 33,232 (US $ 440) (IQR 19,609-45,373). The multivariable analysis showed that ARDS and SOFA score were the independent predictors of ICU admission. Interpretation & conclusions: Hospitalisation for scrub typhus is associated with a substantial healthcare expense. The predictors of increased cost were the presence of acute respiratory distress syndrome (ARDS), shock, increasing sequential organ failure assessment (SOFA) score and duration of hospital stay

RESUMEN

Currency notes could play a signicant role in transmitting pathogenic microorganisms amongst individuals in the society. This study was aimed to determine the microbial prole and Antibiotic susceptibility of bacterial pathogens isolated from Ethiopian paper notes in circulation. 64 currency paper notes of different denomination were tested for bacterial contamination using standard microbiological methods. Antibiotic susceptibility proles of the isolates were determined with approved methods. Results were analyzed using descriptive statistics. Overall mean AMBC was 4.08 log units, with the highest 6.58 log units recorded from denomination 5 followed by 4.50, 3.03, 2.20 log units from denominations 10, 50 and 100 respectively. Total Coliforms (TC) displayed the same pattern with the highest mean counts of 6.52 log units, from denomination 5 and lowest counts of 2.19 log units from denomination 100. Out of 64 currency notes, 35 (54.7%) were contaminated with bacteria. The predominant bacteria isolates were E. coli (60.5%), Salmonella spp. (23.6%) and Shigella spp. (13.2%). Each isolate was resistant to four or more antibiotics tested. All isolates were resistant against Cefepime and Tetracycline and sensitive to Ceftriaxone. This study revealed that currency notes are contaminated with pathogenic bacteria and in most cases these bacterial isolates were resistant to commonly prescribed antibiotics. Therefore, contaminated notes are identied as potential public health threat, because pathogens can be spread by circulating the notes and become source of infection. Awareness creation is important among public in this regard.

RESUMEN

Abstract Introduction Resilience is the capacity in which the qualities and resources of the individual help in the successful coping of adverse situations. Studying the construct of resilience requires seeing it as a process and not only a characteristic of the individual. Saavedra's resilient response is a model that fits this idea and explains resilience satisfactorily. Having a measuring instrument for health personnel working in hospitals would allow discovering its benefits as a protective factor in the workplace. Objective Adapt and validate the Resilience Scale SV-RES in hospital health professionals in Mexico. Method Based on recent research literature, including response models and modified and adapted items from the Resilience Scale SV-RES, a total of 909 health professionals responded. Distribution, factor analysis, and internal consistency tests were performed. Results The process led to a scale of 28 items grouped into six factors with an overall internal consistency of (α = .908) and 50.5% of explained variance. Discussion and conclusion The Resilience Scale SV-RES has adequate psychometric properties that make it appropriate to measure the resilience capacity of hospital health professionals in Mexico.


Resumen Introducción La resiliencia es la capacidad en que las cualidades y recursos del individuo le ayudan al afrontamiento exitoso de situaciones adversas. Se ha advertido que estudiar el concepto de resiliencia requiere verse como un proceso y no sólo como elementos característicos del individuo, un modelo que explica de manera adecuada este proceso es el modelo de respuesta resiliente de Saavedra. Contar con un instrumento que permita su medición en personal de salud hospitalario permitiría descubrir su beneficio como factor protector en el lugar de trabajo y diseñar intervenciones preventivas o remediales. Objetivo Adaptar y validar la Escala de Resiliencia SV-RES en profesionales de salud hospitalaria en México. Método Se tomó como base la literatura de investigación científica contemporánea, modelos de respuesta resiliente y los reactivos de la Escala de Resiliencia SV-RES, adaptados y modificados, a los que respondieron 909 profesionales de la salud. Se realizaron pruebas de distribución, análisis factorial y consistencia interna. Resultados Se obtuvo una escala conformada por 28 reactivos agrupados en seis factores con consistencia interna global de (α = .908) y una varianza explicada de 50.5%. Discusión y conclusión La Escala de Resiliencia SV-RES cuenta con propiedades psicométricas adecuadas que la hacen apropiada para medir la capacidad de resiliencia en profesionales de la salud hospitalaria de México.
