RESUMEN
El síndrome de Wells o celulitis eosinofílica es una enfermedad inflamatoria de origen desconocido, de aparición infrecuente en la edad pediátrica. Suele manifestarse clínicamente como placas eritematoedematosas, nódulos, pápulas, ampollas, entre otros. Se presenta una paciente en edad pediátrica con nódulos subcutáneos asintomáticos generalizados asociados a eosinofilia grave. El estudio histopatológico de las lesiones fue compatible con celulitis de Wells. Se realizó una evaluación interdisciplinaria en busca de la causa y trastornos eosinofílicos asociados, sin resultados positivos. Se indicó tratamiento sistémico con corticoides y presentó buena respuesta, pero, ante la recidiva de las lesiones tras su suspensión, se indicó dapsona como tratamiento de segunda línea, con mejoría posterior de las lesiones y de la eosinofilia. El objetivo del reporte es presentar una paciente con una manifestación atípica de síndrome de Wells y su desafío terapéutico.
Wells' syndrome, or eosinophilic cellulitis, is an inflammatory disease of unknown origin, uncommon in the pediatric age. It usually appears clinically as erythematous and edematous plaques, nodules, papules, blisters, among other symptoms. Here we describe the case of a female pediatric patient with generalized, asymptomatic subcutaneous nodules associated with severe eosinophilia. The histopathological examination of the lesions was compatible with Wells' syndrome. An interdisciplinary evaluation was performed to establish the cause and look for associated eosinophilic disorders; the results were negative. Systemic corticosteroids were indicated and the patient had a good response; however, in view of the recurrence of the lesions after treatment discontinuation, dapsone was indicated as a second-line treatment, with subsequent improvement of the lesions and eosinophilia. The aim of this report was to describe the case of a female patient with an atypical manifestation of Wells' syndrome and the resulting therapeutic challenge.

Introducción. Durante 2020 y 2021, la circulación de los virus influenza se mantuvo por debajo de lo esperado en todo el mundo. En Argentina, en el año 2022 observamos una circulación ininterrumpida de influenza todo el año. Nuestros objetivos fueron describir los patrones de circulación y las características clínicas de niños internados con influenza. Población y métodos. Estudio retrospectivo, analítico, observacional. Se incluyeron todos los niños internados en un centro pediátrico con detección del virus influenza durante los años 2019-2022. Resultados. Se internaron 138 pacientes en 4 años; en 2019 se observó una tasa del 4,5/1000 egresos hospitalarios mientras que en 2022, fue del 15,1/1000. En 2020 y 2021 no hubo casos. En el 2019 la mayoría de los casos ocurrieron en invierno, la causa de la internación fue la infección respiratoria aguda baja (IRAB) en el 79 % y se detectó influenza A en el 92 % de los casos. En el 2022, la mayoría de los casos ocurrieron en primavera, el 62 % presentó IRAB y en el 56 % se detectó influenza A. Ambos períodos tuvieron similares frecuencias de vacunación y de comorbilidades. Conclusiones. En el 2022 se registraron más internaciones por influenza, lo que podría corresponder a que se realizaron métodos diagnósticos moleculares, que son más sensibles, y se observó un cambio en la estacionalidad con más casos en primavera. En 2019 predominó influenza A en infecciones del tracto respiratorio inferior, mientras que en el 2022 influenza A y B fueron similares, y hubo más formas extrapulmonares.
Introduction. During 2020 and 2021, the circulation of influenza virus remained below expectations worldwide. In Argentina, in 2022, we observed an uninterrupted circulation of influenza all year round. Our objectives were to describe the circulation patterns and clinical characteristics of hospitalized children with influenza. Population and methods. Retrospective, analytical, observational study. All children with influenza virus admitted to a children's hospital during the 20192022 period were included. Results. A total of 138 patients were admitted over 4 years; in 2019, the rate of hospital discharges was 4.5/1000, compared to 15.1/1000 in 2022. No cases were recorded in 2020 and 2021. In 2019, most cases were observed in the winter; in 79%, the cause was acute lower respiratory tract infection (ALRTI); influenza A was detected in 92%. In 2022, most cases occurred in the spring; 62% developed ALRTI; and influenza A was detected in 56%. Similar rates of vaccination and comorbidities were observed in both periods. Conclusions. In 2022, more hospitalizations due to influenza were recorded, which may have correlated with the use of more sensitive molecular diagnostic testing and a change in seasonality, with more cases observed in the spring. In 2019, influenza A predominated in lower respiratory tract infections, while in 2022, cases of influenza A and B were similar, with more extra-pulmonary forms.

La espondiloencondrodisplasia con desregulación inmune relacionada a ACP5 (SPENCDI #607944, por la sigla de spondyloenchondrodysplasia with immune dysregulation y el número que le corresponde en OMIM, Online Mendelian Inheritance in Man) es una displasia inmuno-ósea poco frecuente con manifestaciones heterogéneas y gravedad variable. Presenta lesiones espondilometafisarias, disfunción inmune y compromiso neurológico. Se reportan aspectos clínicos, radiológicos y genéticos de cuatro niñas con SPENCDI en un hospital pediátrico. Todas presentaron manifestaciones esqueléticas y tres de ellas enfermedad inmunológica grave. Se encontró en tres pacientes la variante probablemente patogénica c.791T>A; p.Met264Lys en homocigosis, y en una paciente las variantes c.791T>A; p.Met264Lys y c.632T>C; p.lle211Thr (variante de significado incierto con predicción patogénica según algoritmos bioinformáticos) en heterocigosis compuesta en ACP5. La presencia de la variante repetida c.791T>A sugiere la posibilidad de un ancestro en común en nuestra población. El reconocimiento y diagnóstico de esta entidad es importante para lograr un oportuno abordaje, que deberá ser multidisciplinario, orientado hacia la prevención de posibles complicaciones.
Spondyloenchondrodysplasia with immune dysregulation related to ACP5 (SPENCDI, OMIM number 607944) is an uncommon immune-skeletal dysplasia with heterogeneous manifestations and variable severity. It is characterized by spondylar and metaphyseal lesions, immune dysfunction, and neurological involvement. Here we report the clinical, radiological and genetic aspects of 4 girls with SPENCDI treated at a children's hospital. They all had skeletal manifestations and 3 developed severe immune disease. In 3 patients, the likely pathogenic variant c.791T>A; p.Met264Lys (homozygous mutation) was observed, while 1 patient had variants c.791T>A; p.Met264Lys and c.632T>C; p.lle211Thr (variant of uncertain significance with pathogenic prediction based on bioinformatics algorithms) caused by a compound heterozygous mutation in ACP5. The repeated presence of variant c.791T>A suggests the possibility of a common ancestor in our population. The recognition and diagnosis of this disorder is important to achieve a timely approach, which should be multidisciplinary and aimed at preventing possible complications.

Background@#Yerba mate (YM, Ilex paraguariensis) consumption beneficially affects the bones. However, whether YM components exert their effect on bone cells directly remains elusive. @*Methods@#We evaluated how main YM components affect osteoblastic (MC3T3-E1) and osteocytic (MLO-Y4) cells in vitro when administered separately or in an aqueous extract. MC3T3-E1 and MLO-Y4 cells were exposed to three different experimental conditions: (1) Caffeine, chlorogenic acid, and their combinations; (2) Caffeine, rutin, and their combinations; (3) Aqueous YM extract. @*Results@#All polyphenol and caffeine concentrations as well as that of their tested combinations significantly increased MC3T3-E1 cell viability from 16.6% to 34.8% compared to the control. In MLO-Y4 cells, the lowest rutin and the two highest caffeine concentrations significantly increased cell viability by 11.9, 14.9, and 13.7%, respectively. While rutin and caffeine combinations tended to increase MLO-Y4 cell viability, different chlorogenic acid and caffeine combinations did not affect it. Finally, the aqueous YM extract significantly increased MLO-Y4, MC3T3-E1, and differentiated MC3T3-E1 cell viability compared to the control without treatment. @*Conclusions@#YM components (rutin, chlorogenic acid, and caffeine) positively affected bone cells, mainly pre-osteoblast cells. Moreover, the aqueous YM extract significantly increased MLO-Y4, MC3T3-E1, and differentiated MC3T3-E1 cell viabilities indicating an additional relevant nutritional property of YM infusion. Further studies would be required to elucidate the underlying effector mechanism of YM on the bones and its relationship with previously described in vivo positive effects.
RESUMEN
Human reflexes are simple motor responses that are automatically elicited by various sensory inputs. These reflexes can provide valuable insights into the functioning of the nervous system, particularly the brainstem and spinal cord. Reflexes involving the brainstem, such as the blink reflex, laryngeal adductor reflex, trigeminal hypoglossal reflex, and masseter H reflex, offer immediate information about the cranial-nerve functionality and the overall state of the brainstem. Similarly, spinal reflexes such as the H reflex of the soleus muscle, posterior root muscle reflexes, and sacral reflexes provide crucial information about the functionality of the spinal cord and peripheral nerves. One of the critical benefits of reflex monitoring is that it can provide continuous feedback without disrupting the surgical process due to no movement being induced in the surgical field. These reflexes can be monitored in real time during surgical procedures to assess the integrity of the nervous system and detect potential neurological damage.It is particularly noteworthy that the reflexes provide motor and sensory information on the functional integrity of nerve fibers and nuclei. This article describes the current techniques used for monitoring various human reflexes and their clinical significance in surgery. We also address important methodological considerations and their impact on surgical safety and patient outcomes. Utilizing these methodologies has the potential to advance or even revolutionize the field of intraoperative continuous monitoring, ultimately leading to improved surgical outcomes and enhanced patient care.
RESUMEN
ABSTRACT Purpose: The possible variability in diagnostic test results is a statistical feature of dry eye disease patients. The clinician should consider tear film variations over time since the timing of tear film measurements is important for proper diagnosis. The purpose of the present study was to analyze the inter-week variation of osmolarity measurement in healthy and dry eye disease participants. Methods: Based on the Dry Eye Workshop II (DEWS-II) diagnostic methodology report criteria, a battery of tests (Ocular Surface Disease Index [OSDI] questionnaire, breakup time, and corneal staining) was administered to rule out the presence of dry eye disease. A total of 40 qualified volunteers were recruited into two groups: with only 20 healthy and 20 dry eye disease participants. The inter-week variation of osmolarity in the two groups was measured using a TearLab osmometer in two sessions one-week apart. The differences between the results were calculated. Results: There were no significant differences in osmolarity between the two sessions for either the healthy (paired t-test; p=0.085) or dry eye disease (paired t-test; p=0.093) participants. Moreover, there was no significant correlation between the means and differences in either session on healthy (Pearson correlation: r=0.020; p=0.935) or dry eye disease (Pearson correlation: r=-0.022; p=0.928) participants. In session 1, there was a significant difference in osmolarity values between groups (unpaired t-test; p=0.001), but no difference was found in session 2 (unpaired t-test; p=0.292). Conclusions: The present study discovered no inter-week variation in the tear film osmolarity of healthy and dry eye disease participants classified based on the DEWS-II criteria.
RESUMO Objetivo: A possível variabilidade nos resultados de testes diagnósticos é uma característica estatística dos pacientes com síndrome do olho seco. O médico deve considerar as variações do filme lacrimal ao longo do tempo, pois o momento em que o filme lacrimal é medido pode ser crítico para o diagnóstico adequado. O objetivo deste estudo foi analisar a variação semanal da osmolaridade do filme lacrimal em participantes saudáveis e em outros com síndrome do olho seco. Métodos: Com base nos critérios da metodologia de diagnóstico do relatório da Dry Eye Workshop II (DEWSII), foi aplicada uma bateria de testes (questionário do índice de doença da superfície ocular [OSDI], tempo de ruptura do filme lacrimal e coloração da córnea) para descartar a presença de síndrome do olho seco. Um total de 40 voluntários qualificados foi recrutado e distribuído em dois grupos de 20 participantes saudáveis e 20 participantes com síndrome do olho seco. A variação da osmolaridade entre semanas foi medida com um osmômetro TearLab em duas sessões com uma semana de intervalo nos dois grupos. As diferenças entre os resultados foram então calculadas. Resultados: Não foram encontradas diferenças significativas na osmolaridade entre as medidas obtidas nas duas sessões, nem no grupo de participantes saudáveis (teste de t pareado; p=0,085), nem no de participantes com síndrome do olho seco (teste de t pareado; p=0,093). Não foi detectada nenhuma correlação significativa entre as médias e diferenças entre as duas sessões entre participantes saudáveis (correlação de Pearson: r=0,020, p=0,935) e aqueles com síndrome do olho seco (correlação Pearson: r=-0,022, p=0,928). Foi encontrada uma diferença significativa nos valores de osmolaridade entre os dois grupos na primeira sessão (teste de t não pareado; p=0,001), mas nenhuma diferença foi encontrada na segunda sessão (teste de t não pareado; p=0,292). Conclusões: O presente estudo não encontrou variação entre semanas consecutivas na osmolaridade do filme lacrimal em participantes saudáveis e com síndrome do olho seco, classificados com base nos critérios do DEWSII.
RESUMEN
Resumen Antecedentes: Chlamydia trachomatis es la bacteria que se detecta con mayor frecuencia en las infecciones de transmisión sexual. Se han identificado 20 genotipos de C. trachomatis mediante el gen ompA y varias genovariantes mediante el análisis de polimorfismo de un solo nucleótido (SNP). En México, el genotipo F es el más frecuente. Objetivo: Identificar la existencia de subtipos del genotipo F. Método: Se analizaron siete cepas del genotipo F de C. trachomatis aisladas en 2011, mediante secuenciación de nucleótidos y mapeo con enzimas de restricción. Resultados: El análisis de SNP mostró dos cepas con el mismo SNP en el nucleótido 288 (C288T), mientras que con enzimas de restricción se identificó una variante con diferente RFLP (polimorfismo de la longitud de fragmentos de restricción) cuando se tratan con la mezcla de enzimas HinfI y TaqI. Conclusión: En México se encuentran dos subtipos del genotipo F y solo las enzimas de restricción HinfI y TaqI pueden identificar la existencia de uno de estos genotipos F.
Abstract Background: Chlamydia trachomatis is the most frequently identified bacterium in sexually transmitted infections. Twenty C. trachomatis genotypes have been determined using the ompA gene and several genovariants by single nucleotide polymorphism (SNP) analysis. In Mexico, the F genotype is the most frequent. Objective: To identify subtypes of the F genotype. Method: Seven C. trachomatis genotype F strains isolated in 2011 were analyzed by nucleotide sequencing and restriction enzyme mapping. Results: SNP analysis showed two strains with the same SNP at nucleotide 288 (C288T), while with res-triction enzymes, a variant with different RFLP (restriction fragment length polymorphism) was identified when treated with the mixture of HinfI and TaqI enzymes. Conclusion: In Mexico, there are two subtypes of F, and only with restriction enzymes HinfI and TaqI can identify one of the genovariants of the F genotype.
RESUMEN
La termografía por infrarrojo (TI) permite evaluar la temperatura corporal, medir los cambios en la disipación del calor corporal en superficie y relacionarlos con las características de composición corporal e índices antropométricos. Aumentar el número de registros de zonas corporales evaluadas con TI y establecer las relaciones de estas temperaturas (32 áreas corporales) con variables de composición corporal e índices antropométricos, como el índice de masa corporal (IMC), índice cintura cadera, índice cintura estatura, en hombres adultos divididos según su estado ponderal. Participaron 60 hombres, adultos sanos, divididos en 2 grupos: grupo 1 (n=30), con IMC ≤ 24,9, edad 23,2 ± 3,9 años, masa corporal 66,5 ± 6,5 kg, y talla 170,5 ± 7,4 cm; y, grupo 2 (n= 30), con IMC > 24,9, edad 29,4 ± 9,9 años, masa corporal 84,5 ± 11,9 kg, y talla 172,0 ± 7,18 cm. Se realizaron evaluaciones antropométricas y de TI. Sujetos con IMC ≤ 24,9 kg/ m2 presentaron valores mayores de temperatura superficial, en todas las zonas estudiadas, a diferencia de los sujetos con niveles de IMC > 24,9 kg/m2, donde la disipación del calor corporal fue menor. Existe una estrecha relación entre la temperatura superficial de la piel y el IMC, donde sujetos con un IMC normal mostraron una disipación de calor y valores de temperatura superficial mayores, en todas las zonas evaluadas, a diferencia de los sujetos con un IMC que se encontraba por encima del límite de normalidad.
SUMMARY: Infrared thermography (IT) makes it possible to assess body temperature, measure changes in body heat dissipation on the surface, and relate them to body composition characteristics and anthropometric indices. The objective of this study was to increase the number of records of body areas evaluated with IT and establish the relationships of these temperatures (32 body areas) with body composition variables and anthropometric indices, such as body mass index (BMI), waist-hip ratio, waist-height ratio, in adult men divided according to their weight status. A total of 60 healthy adult men participated, divided into 2 groups: group 1 (n=30), with a body mass index (BMI) ≤ 24.9, age 23.2 ± 3.9 years, body mass 66.5 ± 6.5 kg, and height 170.5 ± 7.4 cm; and, group 2 (n = 30), with BMI > 24.9, age 29.4 ± 9.9 years, body mass 84.5 ± 11.9 kg, and height 172.0 ± 7.18 cm. Anthropometric and IT assessments were performed. Subjects with BMI ≤ 24.9 kg/ m2 presented higher values of surface temperature in all areas studied, unlike subjects with BMI levels > 24.9 kg/m2, where body heat dissipation was lower. There is a close relationship between skin surface temperature and BMI, where subjects with a normal BMI showed higher heat dissipation and surface temperature values, in all evaluated areas, unlike subjects with a BMI that was above the normal limit.

Resumen Antecedentes: Desde hace treinta años, México ha estudiado la carga de la enfermedad para sustentar decisiones en salud. Objetivo: Analizar la carga de enfermedad, lesiones y factores de riesgo en México entre 1990 y 2021. Material y métodos: Se utilizaron las estimaciones del Global Burden of Disease 2021 para analizar la mortalidad, los años de vida perdidos por muerte prematura, los años vividos con discapacidad y los años de vida saludable perdidos, así como la carga atribuible a los factores de riesgos por sexo, edad y entidad federativa. Resultados: La mortalidad infantil disminuyó 39.4 % de 1990 a 2000, y 49.0 % de 2000 a 2019. En el ámbito nacional, la mortalidad decreció 27.5 % entre 1990 y 2019, pero ascendió en 2020 y 2021 en todos los estados, especialmente en adultos de 35 a 64 años, debido a la pandemia de COVID-19, que contribuyó con 24.3 % de las defunciones en 2019. Se observaron diferencias significativas en la mortalidad según la edad y el sexo. La carga atribuible a los factores de riesgo metabólicos se incrementó, mientras que la atribuible el consumo de alcohol y tabaco disminuyó. El acceso al agua potable y saneamiento mejoró. Conclusiones: Evaluar la carga de enfermedad es crucial para diseñar estrategias eficaces para abordar las necesidades actuales y los futuros desafíos en salud.
Abstract Background: For thirty years, Mexico has studied the burden of disease in order to inform health decisions. Objective: To analyze the burden of disease, injuries, and risk factors in Mexico between 1990 and 2021. Material and methods: Estimates from the Global Burden of Disease 2021 study were used to analyze mortality, years of life lost due to premature mortality, years lived with disability and disability-adjusted life years, as well as the burden attributable to risk factors by sex, age and state of the country. Results: Infant mortality decreased by 39.4% from 1990 to 2000 and by 49.0% from 2000 to 2019. At the national level, mortality decreased by 27.5% between 1990 and 2019, but increased in 2020 and 2021 across all states, especially in adults aged from 35 to 64 years due to the COVID-19 pandemic, which contributed with 24.3% of deaths in 2019. Significant differences in mortality were observed according to age and sex. The burden attributable to metabolic risk factors did increase, while alcohol and tobacco consumption decreased. Access to drinking water and sanitation showed improvements. Conclusions: Assessing the burden of disease is crucial in order to design effective strategies to address current health needs and future healthcare challenges.
RESUMEN
Resumen Antecedentes: Los trastornos musculoesqueléticos (TME) afectan a 1710 millones de personas en todo el mundo y es la principal causa de discapacidad. Objetivo: Analizar los años vividos con discapacidad (AVD) por TME en México entre 1990 y 2021. Material y métodos: Con las estimaciones del estudio de la Carga Global de la Enfermedad 2021 se analizaron los AVD por TME y sus seis categorías: osteoartritis, artritis reumatoide, gota, dolor cervical, lumbalgia y otros TME. Se evaluaron patrones y tendencias del número, tasa cruda y tasa estandarizada por edad de los AVD a nivel nacional, estatal, por grupos de edad y sexo. Resultados: Los TME constituyeron la principal causa de AVD en México entre 1990 y 2021, con un incremento de 57.3 %; pasaron de 1458.4 a 2293.7 por 100 000 habitantes. La lumbalgia (840.6 AVD) destacó con la mayor tasa en 2021 y la osteoartritis, con el mayor incremento. Los TME se incrementaron con la edad y, con excepción de la gota, afectaron más a las mujeres. Conclusiones: De 1990 a 2021, los TME constituyeron la principal causa de AVD en México, con mayor impacto en adultos y mujeres. Los TME se evidencian desde edades tempranas, de ahí la necesidad de intervenciones continuas para preservar la calidad de vida.
Abstract Background: Musculoskeletal disorders (MSD) affect 1.71 billion people worldwide and are the leading cause of disability. Objective: To analyze the years lived with disability (YLD) attributed to MSD in Mexico between 1990 and 2021. Material and methods: With estimates from the Global Burden of Disease 2021 study, the YLDs due to MSD and their six categories were analyzed, including osteoarthritis, rheumatoid arthritis, gout, neck pain, low back pain, as well as other MSDs. Patterns and trends in the number, crude rate, and YLD age-standardized rate were evaluated at the national and state levels, as well as by age group and gender. Results: MSDs were the main cause of YLDs in Mexico between 1990 and 2021, with an increase of 57.3%, going from 1,458.4 to 2,293.7 per 100,000 population. Low back pain (840.6 YLD) showed the highest rate in 2021, while osteoarthritis had the largest increase. MSDs increased with age and, and except for gout, affected women more often. Conclusions: From 1990 to 2021, MSDs were the main cause of YLDs in Mexico, with a higher impact on adults and women. MSDs can appear early in life, hence the need for continuous interventions in order to preserve quality of life.
RESUMEN
Resumen Antecedentes: Durante décadas, México ha transitado de las enfermedades infecciosas a las crónicas y la violencia, debido a cambios en los estilos de vida y la urbanización. Objetivo: Describir el impacto en salud de los factores de riesgo en México entre 1990 y 2021. Material y métodos: Se utilizaron las estimaciones del Global Burden of Disease para analizar la mortalidad y años de vida saludable (AVISA) perdidos atribuibles a factores de riesgo, estratificados por edad, sexo y estado. Resultados: Los factores de riesgo representaron 14.9 millones de AVISA en 2021, 32.4 % del total nacional, con predominio de los riesgos metabólicos (19.8 %). La mortalidad estandarizada por edad debida a estos riesgos se incrementó 6.5 % de 1990 a 2021 y los riesgos conductuales y ambientales se redujeron en más de 50 %. Los factores predominantes cambiaron de desnutrición, problemas de acceso al agua potable y saneamiento en 1990 a altos niveles de glucosa y obesidad en 2021; la desnutrición fue el mayor riesgo en los niños menores de cinco años. Conclusiones: México afronta desafíos sanitarios dobles, la desnutrición infantil continúa y los riesgos metabólicos en adultos se incrementan, sobre todo en los estados menos desarrollados, por lo que se requieren intervenciones específicas para amenazas nuevas y existentes.
Abstract Background: Over the past decades, Mexico's health landscape has shifted from infectious to non-communicable diseases and violence, mirroring lifestyle, urbanization, and developmental changes. Objective: To describe the impact of risk factors on health in Mexico from 1990 to 2021. Material and methods: Using the Global Burden of Diseases, Injuries, and Risk Factors Study estimates, we describe risk factor-related mortality and disability adjusted life years (DALYs) in Mexico (1990-2021) by age, sex, and state of the country. Results: In 2021, risk factors led to 14.9 (12.9-16.7) million DALYs, which accounted for 32.4 % of Mexico's burden. Metabolic risks, with 19.8% (17.0-21.9 %) were the main contributors. From 1990 to 2021, the age-standardized all-cause mortality rate associated with metabolic risks increased by 6.5%, while behavioral and environmental risks decreased by more than 50%, with marked variations between states. The predominant risk factors shifted from malnutrition and unsafe water and sanitation in 1990 to high glucose and body mass index in 2021. Malnutrition-related risks have the highest impact on health loss in children younger than 5 years. Conclusions: Mexico faces a dual health challenge: childhood malnutrition persists, and adult metabolic risks are on the rise, particularly in less developed states, with targeted interventions for traditional and emerging health threats being required.
RESUMEN
Resumen Antecedentes: Se estima que los factores de riesgo ambientales (FRA) fueron responsables en 2019 de nueve millones de muertes en el mundo. Objetivo: A partir de datos del estudio Global Burden of Disease, se analizaron indicadores de pérdida de salud asociada a la exposición a FRA en México. Material y métodos: Se analizaron números absolutos y porcentajes poblacionales de muertes y años de vida saludable (AVISA) perdidos según sexo atribuidos a FRA seleccionados en los ámbitos nacional y estatal, así como las tendencias estandarizadas por edad de 1990 a 2021. Resultados: En 2021, la contaminación por material particulado en ambiente exterior mostró la mayor mortalidad y AVISA perdidos por los FRA seleccionados (42.2 y 38.1 %, respectivamente), seguida de la exposición a plomo (20.6 y 13.4 %) y temperatura baja (19.8 y 12.3 %). Ambos indicadores han disminuido en todos los FRA seleccionados, en magnitudes diferentes entre 1991 y 2021, excepto la temperatura alta. Conclusiones: A pesar de las disminuciones en los últimos 32 años, el material particulado en ambiente exterior mostró la mayor mortalidad y AVISA perdidos, seguido de la exposición a plomo. Es fundamental fortalecer las políticas de calidad del aire y exposición a plomo en México.
Abstract Background: It is estimated that environmental risk factors (ERF) were responsible for nine million deaths worldwide in 2019. Objective: Using data from the Global Burden of Disease study, indicators of health loss associated with exposure to ERF in Mexico were analyzed. Material and methods: Absolute numbers and population percentages of deaths and disability-adjusted life years (DALY) lost attributed to selected ERFs were analyzed at the national and state level and by sex, as well as age-standardized trends from 1990 to 2021. Results: In 2021, ambient particulate matter pollution showed the highest mortality and DALYs lost attributed to selected ERFs (42.2 and 38.1% respectively), followed by lead exposure (20.6 and 13.4%) and low temperature (19.8 and 12.3%). Both indicators have decreased for all selected ERAs by different magnitudes between 1991 and 2021, except for high temperature. Conclusions: Despite decreases in the last 32 years, outdoor environment particulate matter showed the highest mortality and DALYs lost, followed by lead exposure. It is essential to strengthen air quality and lead exposure policies in Mexico.
RESUMEN
Resumen Antecedentes: Las enfermedades respiratorias (ER) se analizan individualmente, posiblemente con subestimación de su carga total. Objetivo: Analizar la carga de las ER en México para población de 20 años o más de 1990 a 2021. Material y métodos: Se presenta la carga de ER en México a partir de estimaciones del estudio Global Burden of Disease en cuanto a mortalidad y años de vida saludable (AVISA) perdidos que comprenden recuentos, tasas por 100 000 y tasas estandarizadas por edad. Las ER se categorizaron en enfermedades respiratorias crónicas (ERC), infecciones respiratorias y cánceres respiratorios. Resultados: En 2021, las ER causaron la muerte de 336 728 adultos mayores de 20 años, lo que representó 30.5 % del total de defunciones, incremento cercano al triple respecto a 2019, principalmente debido a COVID-19. Las ERC contribuyeron con 3.4 % del total de muertes, las infecciones respiratorias con 25.9 % y los cánceres respiratorios con 1.2 %. La mortalidad y AVISA perdidos por ERC se incrementaron persistentemente, con variaciones entre los estados. Las tasas de mortalidad ajustadas por edad de las ERC disminuyeron desde 1990, excepto las enfermedades pulmonares intersticiales, que se incrementaron constantemente. Conclusión: Los significativos niveles de mortalidad y discapacidad debidos a enfermedades respiratorias en México exigen mejorar la prevención, investigación y abordar factores de riesgo como tabaquismo y contaminación, además de fomentar la capacitación médica continua.
Abstract Background: Respiratory diseases (RD) are often analyzed separately rather, possibly leading to an underestimation of their total burden. Objective: To analyze the burden of RD in Mexico for population aged 20 or older from 1990 to 2021. Material y methods: We present the burden of RD in Mexico based on estimates of the Global Burden of Disease study for mortality and disability-adjusted life years (DALYs), comprising counts, rates per 100,000, as well as age-standardized rates. RDs were categorized into three key groups: chronic respiratory diseases (CRD), respiratory infections (RI), and respiratory cancers. Results: In 2021, among those aged 20+, RDs were responsible for 336,728 deaths, which accounts for 30.5% of total deaths— a nearly threefold increase since 2019, primarily due to the COVID-19 pandemic. CRDs contributed with 3.4% of total deaths; RIs, with 25.9%; and respiratory cancers, with 1.2%. CRDs showed a continuous rise in deaths, crude mortality, and DALY rates across genders, with no signs of leveling. RD burden varied widely across states. Age-standardized CRD mortality rates have generally declined since 1990, except for interstitial lung diseases, which have consistently increased. Conclusion: The significant burden of mortality and disability due to RDs in Mexico underscores the necessity for enhanced prevention, research, and for addressing risk factors such as smoking and pollution. Ongoing healthcare training can help reduce RD burden.
RESUMEN
Abstract: This study aimed to compare the mechanical and functional muscle performance of three different competitive soccer teams of the Costa Rica professional league (U17, Pro A, and Pro B). Age 20.09 ± 4.32 years old, weight body mass 70.85 ± 7.45 kg, height 174.56 ± 4.97 cm; body fat percentage 13.9 ± 5.06 %; lean body mass 57.90 ± 4.88 kg; lean body mass right lower limb 10.11 ± 0.87 kg; lean body mass leth lower limb 10.09 ± 0.92 kg. The variables assessed were muscle time of contraction, muscle radial displacement, delay time, squat jump, and countermovement jump. The devices used were dual ray absorptiometry, tensiomyography, and jump platform. There were differences in weight, body mass, and body fat % (Pro A< U17<Pro B). There was a difference in group squat jump performance (Pro A> U17). There were no significant differences in muscle time of contraction, delay time, or radial deformation. The knowledge of differences in both muscle functional and mechanical performance could lead to new training and recovery methods and protocols considering the player's professional levels.

Objetivos: Describir la prevalencia del riesgo de deficiencia o exceso en la ingesta de nutrientes y el patrón de consumo de alimentos de acuerdo con las recomendaciones establecidas por el Ministerio de Salud y Protección Social y el Instituto Colombiano de Bienestar Familiar. Materiales y métodos: Se realizó un estudio transversal descriptivo en mujeres sanas que fueron atendidas en dos hospitales del oriente antioqueño, con seguridad alimentaria y nutricional (SAN) según la Escala Latinoamericana y Caribeña de Seguridad Alimentaria (ELCSA), en el primer trimestre de lactancia, evaluadas entre los años 2021 y 2022. La fuente de información fue la historia clínica. Se midieron las características sociodemográficas, clínicas, antropométricas y la ingesta dietética y de micronutrientes. Se empleó estadística descriptiva. Se presenta la prevalencia de déficit o exceso de ingesta calórica y el índice de relación de consumo (IRC). Se utilizaron los software EVINDI v5, PC-SIDE v1.0, Stata 16.1 y Jasp 0.16.4. Resultados: Se incluyeron 30 mujeres lactantes. La prevalencia de riesgo de deficiencia en la ingesta usual de energía fue 43 % y exceso 16 %; el riesgo de deficiencia proteica fue 98 %. El consumo superior al valor de referencia para grasa saturada fue 86 % y carbohidratos simples 72 %. El patrón de consumo se caracterizó por superar las recomendaciones para azúcares (IRC = 1,29), leche y derivados (IRC = 1,09), cereales, raíces, plátanos y tubérculos (IRC = 1,04). No cumplieron las recomendaciones en la ingesta de grasas (IRC = 0,70), carnes, huevos, leguminosas, frutos secos y semillas (IRC = 0,49), frutas y verduras (IRC = 0,41). Conclusiones: El patrón alimentario identificado dista de las guías nacionales, lo que limita el consumo de macro y micronutrientes, y contribuye al círculo intergeneracional de la malnutrición. Es fundamental realizar nuevas investigaciones en el país para identificar otros patrones de consumo e impulsar acciones de política al respecto.
Objectives: To describe the prevalence of the risk of under or overnutrition and the food intake pattern vis á vis the recommendations of the Ministry of Health and Social Protection and the Colombian Family Welfare Institute. Material and methods: Descriptive cross-sectional study carried out in healthy women receiving care in two hospitals of eastern Antioquia, with food and nutrition security in accordance with the Latin American and Caribbean Food Security Scale (ELCSA), in the first trimester of breastfeeding, assessed between 2021 and 2022. The clinical record was used as the source of information. The sociodemographic, clinical, anthropometric characteristics, as well as dietary and micronutrient intake, were measured. Descriptive statistics were used. The prevalence of deficient or excessive energy intake and the food consumption score (FCS) are presented. The EVINDI v5, PC-SIDE v1.0, Stata 16.1 and Jasp 0.16.4 software packages were used. Results: Overall, 30 breastfeeding women were included. The prevalence of the risk of deficient energy intake was 43 %, while the risk of excessive intake was 16 % and the risk of protein deficiency was 98 %. Intake exceeding the reference value for saturated fats was 86 %, and 72 % for simple carbohydrates. The consumption pattern was characterized by exceeding the recommendations for sugars (FCS = 1.29), milk and dairy products (FCS = 1.09), grains, roots, plantains and tubers (FCS = 1.04). Recommendations for the intake of fats (FCS = 0.70), meats, eggs, legumes, nuts, seeds (FCS = 0.49), fruits and vegetables (FCS = 0.41) were not met. Conclusions: The food intake pattern identified is far from meeting the national guidelines, limiting macro and micronutrient intake and contributing to the intergenerational malnutrition cycle. Additional research in the country is essential in order to identify other intake patterns and drive political action.

Purpose: Vascular endothelial growth factor inhibitors (anti?VEGF) have been shown to be effective in the treatment of diabetic macular edema. However, there is little information about the systemic effects of intraocular administration of anti?VEGF drugs in patients with coexistent diabetic nephropathy because it can produce adverse renal effects. Methods: This retrospective cohort study analyzed the effect of intravitreal anti?VEGF drugs (bevacizumab, ranibizumab, or aflibercept) on eFGR and microalbuminuria (MicA) in patients with diabetic macular edema and nonproliferative retinopathy without chronic kidney disease (CKD). Results: Sixty?six patients were included, 54.5% male and 45.5% female, with a mean age of 66.70 ± 11.6 years. The mean follow?up of patients with antiangiogenic treatment was 42.5 ± 28.07 months, and the mean number of injections was 10.91 ± 7.54. In 12.1% of the cases, there was a worsening of the glomerular filtration rate (eFGR) and a 19.7% worsening of the microalbuminuria (MicA). The number of injections was not related to the worsening of the eFGR (P = 0.74) or the MicA (P = 0.239). No relationship was found between the type of drug and the deterioration of the GFR (P = 0.689) or the MicA (P = 0.53). Conclusions: Based on the results, there is a small proportion of patients with increase in MicA and the decrease in eFGR after anti?VEGF therapy, and these was no associated with the number of injection or the drug type. Ophthalmologists should be aware of renal damage in order to do a close monitoring of renal function and proteinuria after intravitreal administration of anti?VEGF mainly in hypertensive patients.
RESUMEN
Introducción. Las cardiopatías congénitas complejas son las malformaciones más frecuentes con una importante carga de morbimortalidad. Se busca conocer el estado de salud y discapacidad de niños operados en un hospital de tercer nivel. Población y métodos. Fueron evaluados en las áreas de crecimiento, neurodesarrollo y discapacidad 84 pacientes entre 21 y 39 meses de edad operados con circulación extracorpórea durante el primer año de vida. Resultados. La mayoría de los niños crece por debajo del percentil 50 en los tres parámetros, con mayor compromiso en aquellos con síndrome genético asociado. La frecuencia de discapacidad fue del 55 %. En el grupo con CC aislada, la gravedad de la cardiopatía y el examen neurológico patológico al alta se asociaron con discapacidad (p = 0,047 y p = 0,03). Contar solo con cobertura de salud pública se asocia a un menor acceso a intervenciones oportunas (p = 0,02). Conclusiones. Cerca de la mitad de los pacientes evoluciona con discapacidad moderada-grave. Es competencia del equipo de salud conocer las morbilidades más allá del aspecto cardiovascular y los factores de riesgo. Las barreras en el acceso a las intervenciones adecuadas advierten a los profesionales sobre la relevancia de buscar estrategias para vencerlas y lograr el máximo potencial de desarrollo de los pacientes.
Introduction. Complex congenital heart defects are the most frequent malformations and entail a significant burden of disease. The objective of this study was to determine the health status and disability of children who underwent surgery at a tertiary care hospital. Population and methods. A total of 84 patients aged 21 to 39 months who had a surgery with extracorporeal circulation during their first year of life were assessed in terms of growth, neurodevelopment, and disability. Results. In most children, growth was below the 50th percentile in all 3 parameters, and greater involvement was observed in those with an associated genetic disorder. The frequency of disability was 55%. In the group with isolated congenital heart disease, the severity of disease and a pathological neurological examination at discharge were associated with disability (p = 0.047 and p = 0.03). Having only public health coverage was associated with less access to timely interventions (p = 0.02). Conclusions. Nearly half of the patients develop moderate-severe disability. Being aware of morbidities beyond the cardiovascular aspect and risk factors is part of the health care team's scope. Barriers in access to appropriate interventions caution health care providers of the relevance of seeking strategies to overcome them and achieve the maximum development potential of patients.

La enfermedad granulomatosa crónica es una inmunodeficiencia primaria poco frecuente, que secaracteriza por defectos en alguna de las subunidades del complejo enzimático nicotinamida adeninadinucleótido fosfato oxidasa, que ocasiona un déficit en la generación de anión superóxido por losfagocitos. Dentro de este grupo, la forma ligada al X es la más frecuente. Se reporta el caso de una paciente de sexo femenino de 2 años con enfermedad granulomatosa crónica autosómica recesiva, con mutación en gen CYBA, quien presentó manifestación inicial de la enfermedad con abscesos cerebrales ocasionados por un germen oportunista (Dermacoccus nishinomiyaensis). Esta infección permitió la sospecha diagnóstica temprana, por lo que recibió el tratamiento y la profilaxis en forma oportuna. Actualmente, se encuentra libre de infecciones, a la espera del trasplante de células progenitoras hematopoyéticas.
Chronic granulomatous disease is a rare primary immunodeficiency characterized by defects in one of the subunits of the nicotinamide adenine dinucleotide phosphate oxidase enzyme complex, which causes a deficiency in the capacity of phagocytes to generate superoxide anion. Within this group, the X-linked form is the most frequent. Here we report the case of a 2-year-old female patient with autosomal recessive chronic granulomatous disease, with a mutation in the CYBA gene, whose initial manifestation was brain abscesses caused by an opportunistic microorganism (Dermacoccus nishinomiyaensis). The infection led to an early diagnostic suspicion, so treatment and prophylaxis were administered in a timely manner. Currently, she is infectionfree, awaiting hematopoietic progenitor cell transplantation.
