Standards for psychosocial care in pediatric cancer: adapted proposal for Latin American and Caribbean countries.

Objective: To highlight the objectives, achievements, challenges, and next steps for the World Health Organization's Global Initiative for Childhood Cancer (GICC) framework, a project designed to improve psychosocial care (PSC) in pediatric cancer centers across Latin America and the Caribbean (LAC). Methods: The project was launched in Peru, the first GICC focal country, in November 2020. The diagnosis phase included a survey and a semistructured interview with health professionals to assess PSC practices in institutions, and a needs assessment survey for caregivers. In the second phase, a strategic plan was developed to address the identified needs, including the adaptation of PSC standards, the establishment of multicenter working groups, the expansion of the proposal, and the development of materials. Results: The study found that PSC was not being adequately provided in accordance with international standards. Six adapted standards were proposed and validated, and more than 50 regional health professionals participated in online activities to support the project. The implementation process is currently ongoing, with the establishment of five multidisciplinary working groups, one regional committee, and the production of 16 technical outputs. Conclusion: This project represents a substantial step forward to improve PSC for pediatric patients with cancer and their families in LAC countries. The establishment of working groups and evidence-based interventions strengthen the proposal and its implementation. Development of health policies that include PSC according to standards is needed to achieve sustainable results in the quality of life of children with cancer and their families.

Lack of changes in preterm delivery and stillbirths during COVID-19 lockdown in a European region.

Preliminary data in Europe have suggested a reduction in prematurity rates during the COVID-19 pandemic, implying that contingency measures could have an impact on prematurity rates. We designed a population-based prevalence proportion study to explore the potential link between national lockdown measures and a change in preterm births and stillbirths. Adjusted multivariate analyses did not show any decrease in preterm proportions during the lockdown period with respect to the whole prelockdown period or to the prelockdown comparison periods (2015-2019): 6.5% (95%CI 5.6-7.4), 6.6% (95%CI 6.5-6.8), and 6.2% (95%CI 5.7-6.7), respectively. Proportions of preterm live births did not change during lockdown when different gestational age categories were analyzed, nor when birthweight categories were considered. No differences in stillbirth rates among the different study periods were found: 0.33% (95%CI 0.04-0.61) during the lockdown period vs. 0.34% (95%CI 0.22-0.46) during the prelockdown comparison period (2015-2019).Conclusion: We did not find any link between prematurity and lockdown, nor between stillbirths and lockdown. Collaborative efforts are desirable to gather more data and additional evidence on this global health issue. What is Known: • Prematurity is associated with increased risk of morbidity and mortality. • Contingency measures during the COVID-19 pandemic may have an impact on reducing prematurity rates. What is New: • Prematurity and stillbirth rates remained stable in Castilla-y-León, a Spanish region, during COVID-19 lockdown. • The role of behavioral patterns and sociocultural factors in the prevention of preterm birth as a result of lockdown measures remains a subject for debate.

Neither dectin-2 nor the mannose receptor is required for resistance to Coccidioides immitis in mice.

We investigated the roles of the mannose receptor (MR) and Dectin-2 in resistance to pulmonary coccidioidomycosis in C57BL/6 (B6) mice and in the interaction of myeloid cells with spherules, using B6 mice with targeted mutations in Mrc1 and Clec4n. Spherules are the tissue form of Coccidioides, and we determined that the MR on bone marrow-derived dendritic cells (BMDC) was important for recognition of spherules (formalin-killed spherules [FKS]) and for secretion of interleukin 10 (IL-10) and proinflammatory cytokines in response to FKS by both elicited macrophages and BMDC. Infected MR knockout (KO) mice produced more IL-10 in their lungs than did B6 mice, and MR KO mice also made more protective Th-17 cytokines. In contrast to the MR, Dectin-2 was not required for recognition of FKS by BMDC or for the production of cytokines by BMDC in response to FKS. However, Dectin-2 KO was required for stimulation of elicited peritoneal macrophages. Despite that, lung cytokine levels were not significantly different in Dectin-2 KO mice and B6 mice 14 days after infection, except for IL-1ß, which was higher in Dectin-2 KO lungs. Although both Dectin-2(-/-) and MR(-/-) myeloid cells had reduced proinflammatory cytokine responses to FKS in vitro, neither MR nor Dectin-2 deficiency reduced the resistance of B6 mice to pulmonary coccidioidomycosis.

Tinea capitis outbreak and other superficial mycosis in an urban community of Medellín / Brote de tinea capitis y otras micosis superficiales en una comunidad urbana de Medellín

Introduction. Dermatophytoses are superficial fungal infections of the keratinized epithelium like tinea capitis. The latte mainly affects school-vulnerable populations. Carpinelo is a peripheral neighborhood in Medellín with poor socioeconomic conditions and where a suspected tinea capitis outbreak took place. Objective. To study and characterize, clinically and microbiologically, patients with suspected dermatophytosis in Carpinelo. Material and methods. We carried out a descriptive and longitudinal study with an active case search of tinea capitis in children and their relatives from the Jardín Educativo Buen Comienzo community in Carpinelo. Patients were clinically evaluated, and samples of scales and hair were taken to perform mycological studies with a 10 % potassium hydroxide and culture in Sabouraud and Mycosel agar. We analyzed the data with the statistical program SPSS™. 25 version. Results. Fifty-seven individuals were studied: 47 were children with a mean age of six years and a ratio of 2:1 male to female. Patients with confirmed diagnosis presented the following clinical forms: tinea capitis (78.95%), tinea faciei (15.79%) or tinea corporis (10.52%). Out of the total, 69.76% of the patients had previous treatment with steroids. The direct test was positive in 53.84% of the samples, and 46.15% had positive cultures. The isolated species were: Microsporum canis (77.77%), Trichophyton spp. (11.11%), Trichophyton rubrum (5.55%), and Malassezia spp. (5.55 %). Conclusion. Tinea capitis was the most common clinical form, and M. canis was the most frequently isolated species. The use of steroids as the first and only option for empiric treatment was worth of notice. The findings of this study point out the importance of microbiological diagnosis in choosing the best treatment for the patients.

Los pacientes con resultados positivos se diagnosticaron con tinea capitis (78,95 %), tinea faciei (15,79 %) y tinea corporis (10,52 %). El 75,43 % de los pacientes recibió tratamiento previo y de estos el 69,73 % fue con esteroides. El examen directo fue positivo en el 53,84 % y los cultivos en el 46,5 % de los casos. Los agentes aislados fueron: Microsporum canis (77,77 %), Trichophyton spp. (11,11 %), Trichophyton rubrum (5,55 %) y Malassezia spp. (5,55 %). Conclusión. Tinea capitis fue la presentación clínica más común y M. canis el dermatofito más frecuentemente aislado. Llamó la atención el uso de esteroides como primera y única opción del tratamiento empírico' lo cual resalta la importancia del diagnóstico microbiológico para proporcionar la terapia apropiada.

[Indicadores de salud perinatal en una región española entre los años 2015 y 2020.] / Perinatal health indicators in a region of Spain corresponding to the period 2015 to 2020.

OBJECTIVE: The availability in the literature of data related to perinatal variables in the Spanish population is very scarce. The aim of this study was to know the evolution of perinatal health indicators according to the risk groups of prematurity and birth weight, the proportion of multiple births, caesarean section and stillbirths. METHODS: We conducted a population-based cross-sectional study of births in eleven hospitals in Castilla y León (January 2015 to June 2020). There were 70,024 newborns from 68,769 deliveries. Jointpoint regression analysis was used to identify changes in trend over the years, and binomial logistic regression was used to adjust for the potential interaction of hospital type, sex, type of delivery and multiple births on the frequencies of prematurity and death. RESULTS: There was a 19.9% decrease in deliveries and a 42% decrease in multiple births, with no change in preterm (7.7%) and stillbirths (0.44%). The percentage of caesarean sections was 21.5% with a slight downward trend over time. Death (stillbirth) was associated with preterm multiple birth; especially with the male-male combination (p<0.05). Late preterm and early term newborns showed higher risk of death compared to term newborns: OR 7.7 (95%CI 5.6-10.7) and 2.4 (95%CI 1.6-3.6), respectively; as well as the low birth weight group (OR 17.6; 95%CI 13.9-22.2) and small for gestational age (OR 3.4; 95%CI 1.9-5.8), compared to those of adequate weight. CONCLUSIONS: Prior to the development of the COVID-19 pandemic there is a decline in births, including multiple births, with no change in stillbirths or prematurity. Late preterm and early term newborns are at increased risk of intrauterine death.

OBJETIVO: La disponibilidad en la literatura de datos relacionados con variables perinatales en la población española son muy escasos. El objetivo de este estudio fue conocer la evolución de los indicadores de salud perinatal atendiendo a los grupos de riesgo de prematuridad y de peso al nacimiento, la proporción de parto múltiple, de cesárea y de mortinatos. METODOS: Se realizó un estudio transversal poblacional de los partos en once hospitales de Castilla y León (enero de 2015 a junio de 2020). Hubo 70.024 recién nacidos (RN) procedentes de 68.769 partos. Se utilizó el análisis de regresión Jointpoint para identificar cambios en la tendencia a lo largo de los años, y la regresión logística binomial para ajustar la potencial interacción del tipo de hospital, el sexo, el tipo de parto y el parto múltiple en las frecuencias de prematuridad y de fallecimiento. RESULTADOS: Hubo un descenso de partos del 19,9% y de los múltiples del 42%, sin cambios en los RN prematuros (7,7%) ni en los mortinatos (0,44%). El porcentaje de cesáreas fue del 21,5% con una ligera tendencia temporal descendente. El fallecimiento (mortinato) se asoció al parto múltiple pretérmino; especialmente a la combinación varón-varón (p<0,05). Los RN pretérminos tardíos y términos precoces mostraron mayor riesgo de fallecer frente a los RN a término: OR 7,7 (IC95% 5,6-10,7) y 2,4 (IC95% 1,6-3,6), respectivamente; así como el grupo de bajo peso (OR 17,6; IC95% 13,9-22,2) y el pequeño para la edad gestacional (OR 3,4; IC95% 1,9-5,8), frente a los de peso adecuado. CONCLUSIONES: Previo al desarrollo de la pandemia por COVID-19 existe un descenso de la natalidad, incluidos los partos múltiples, sin cambios en los mortinatos ni en la prematuridad. Los RN pretérminos tardío y términos precoces tienen mayor riesgo de fallecer intraútero.

Intensive Family Intervention as Support for Professional Treatment: Evolution of Symptoms in a Diagnosed Case of Autism Spectrum Disorder.

This article shows the progress achieved in a child who has received professional treatment combined with a family intervention at home. It discusses a 22-month-old patient identified as showing warning signs of autism spectrum disorder (ASD), a diagnosis that was subsequently confirmed through a standardized ADOS-2 test at 31 months of age. To establish the initial working objectives, a functional diagnosis was carried out at 23 months of age using the Battelle Developmental Inventory; a maturational delay was detected, situating the child at an age equivalent to 16 months. A professional intervention was designed in an early childhood care center, complemented by family intervention, so that the hours in which the child participated in learning experiences were increased. Notable advances were made in the areas of cognitive and motor skills, with more standard scores than when initially evaluated. Progress was also observed (though to a lesser extent) in other developmental areas such as language total, adaptive behavior, and self-help, while slight delays in the areas of socio-emotional development and reasoning and academic skills were found.

Gamification as a Promoting Tool of Motivation for Creating Sustainable Higher Education Institutions.

Higher Educational Institutions (HEIs) are responsible for creating healthy and sustainable environments for students and teachers through diverse educational paradigms such as gamification. In this sense, the Healthy People 2030 and the Sustainable Development Goals indicated the imperative to provide inclusive and equitable quality education to promote a healthy environment and life. The principal objective was to analyse the impact of gamification on health development in HEIs, highlighting their positive and negative effects. To achieve such an objective, a bibliometric analysis was carried out. The 257 documents showed no significant increasing trend in the last decade (p > 0.05) related to the pandemic. Most of the publications were conferences (45%), and the few published articles were the documents with more citations (p < 0.001). According to their index in Journal Citation Reports, there were significant differences between the citations of articles published in journals (p < 0.001). The analysis of journal co-citations showed that the leading journals (such as Computers in Human Behavior) had a significant part in the clusters formed (p < 0.001), conditioning also the keywords, especially the term "motivation". These findings were discussed, concluding that the experimental studies focused on the teachers' adverse effects are yet to come.

Detection of Early Warning Signs in Autism Spectrum Disorders: A Systematic Review.

Due to the exponential increase of autism spectrum disorders' prevalence in Western countries, it is necessary to improve early detection and intervention to enhance developmental milestones. This systematic review identified the most effective screening instrument, which can be used at an early age and which identifies the maximum number of autism cases. We identified several instruments with adequate predictive properties-the Autism Parent Screen for Infants (APSI), Battelle Development Inventory, second edition (BDI-2); Brief Infant-Toddler Social and Emotional Assessment (BITSEA); First Year Inventory (FYI); Infant-Toddler Checklist/Communication and Symbolic Behavior Scales Developmental Profile (ITC/CSBS-DP); Program of Research and Studies on AUTISM (PREAUT-Grid); Checklist for Early Signs of Developmental Disorders (CESDD); Social Attention and Communication Study (SACS); and the Screening Tool for Autism in Toddlers and Young Children (STAT)-that can be applied from 12 months of age in Western countries. The ITC/CSBS-DP has been proposed for universal screening from 12 months of age onwards, complemented by the Modified Checklist for Autism in Toddlers, Revised/Revised with Follow-Up (M-CHAT-R/F), which can be used from 15 months of age onwards. This strategy could improve early detection in at-risk children within the current health system, thus allowing for early intervention.

[Telephone support for breastfeeding by primary care: a randomised multicentre trial]. / Apoyo telefónico de la lactancia materna desde Atención Primaria: ensayo clínico aleatorizado y multicéntrico☆.

OBJECTIVE: To evaluate a telephone support programme for mothers who breastfeed for the first 6 months. METHODS: A randomised unmasked clinical trial was conducted in 5 urban Primary Care centres that included mothers with healthy newborns who were breastfeeding exclusively (EBF) or partially (PBF). The control group received the usual care. The intervention group also received telephone support for breastfeeding on a weekly basis for the first 2months and then every 2weeks until the sixth month. The type of breastfeeding was recorded in the usual check-up visit (1, 2, 4 and 6 months). RESULTS: The study included 193 patients in the intervention group, and 187 in a control group. The greatest increase in the percentage of EBF was observed at 6 months: 21.4% in the control group compared to 30.1% in the intervention group. However, in the adjusted odds ratios analysis, confidence intervals did not show statistical significance. The odds ratio at 1 month, 2 months, 4 months, and 6 months for EBF were 1.45 (0.91-2.31), 1.35 (0.87-2.08), 1.21 (0.80-1.81), and 1.58 (0.99-2.53), respectively. The odds ratio in the same age groups for any type of breastfeeding (EBF + PBF) were 1.65 (0.39-7.00), 2.08 (0.94-4.61), 1.37 (0.79-2.38), and 1.60 (0.98-2.61), respectively. CONCLUSIONS: Telephone intervention was not effective enough to generalise it.

Dectin-1 is required for resistance to coccidioidomycosis in mice.

We assessed the role of Dectin-1 in the immune response to the pathogenic fungus Coccidioides, both in vitro and in vivo, using mice with a targeted mutation in Clec7a. Elicited peritoneal macrophages responded to formalin-killed spherules (FKS) and alkali-treated FKS by secreting proinflammatory cytokines in a Dectin-1- and ß-glucan-dependent manner. The responses of bone marrow-derived dendritic cells (BMDC) to the same stimulants were more complex; interleukin 1ß (IL-1ß) and tumor necrosis factor alpha (TNF-α) secretion was independent of Dectin-1, while IL-6, IL-10, and granulocyte-macrophage colony-stimulating factor (GM-CSF) were largely but not entirely dependent on Dectin-1. After intranasal infection, Dectin-1(-/-) mice had lower concentrations of IL-12p70, gamma interferon (IFN-γ), IL-1ß, and the Th17 cytokines IL-22, IL-23, and 17A in the lung lavage fluid, which may explain why they were significantly more susceptible to pulmonary coccidioidomycosis two weeks after infection. The Dectin-1 mutation was even more deleterious in (B6 × DBA/2)F(2) mice, which are more resistant to coccidioidomycosis than B6 mice by virtue of protective genes from DBA/2, a genetically resistant strain. We also found that two susceptible strains of mice (B6 and BALB/c) expressed much less Dectin-1 in their lungs than did resistant DBA/2 mice. We conclude that Dectin-1 is necessary for resistance to Coccidioides immitis, that Dectin-1 promotes both Th1 and Th17 protective immune responses to this infection, and that there is a correlation between expression of Dectin-1 by the inflammatory infiltrate and resistance to coccidioidomycosis. IMPORTANCE Coccidioidomycosis is a fungal infection endemic in the southwestern United States and neighboring Mexico, causing ~150,000 lung infections in people and resulting in ~17,000 hospitalizations annually in California alone. Very little is known about innate immunity to this fungus. This paper shows that Dectin-1, the primary ß-glucan receptor on myeloid cells, is required for resistance to this pathogen. Dectin-1 is part of the innate immune system, and it is needed to direct the acquired immune response toward into a pathway that will lead to macrophage activation. Lungs from infected mice lacking Dectin-1 had lower concentrations of Th1 and Th17 cytokines, two cytokine pathways that are very important for acquired T cell immunity to Coccidioides spp. This is the first demonstration that Dectin-1 is required for host resistance to a dimorphic, primary pathogenic fungus.

High levels of interleukin-10 impair resistance to pulmonary coccidioidomycosis in mice in part through control of nitric oxide synthase 2 expression.

We have shown previously that there is a direct correlation between IL-10 levels and susceptibility to Coccidioides immitis peritonitis in C57BL/6 (B6), DBA/2, and BXD recombinant inbred mice. We now show that B6 mice are also more susceptible to C. immitis pneumonia and that interleukin-10 (IL-10)-deficient (IL-10-/-) B6 mice are more resistant to C. immitis pneumonia. In addition, we established that high levels of IL-10 are sufficient to make genetically resistant mice susceptible to both C. immitis peritonitis and pneumonia by infecting h.IL-10 transgenic mice. Infected h.IL-10 transgenic mice express lower levels of gamma interferon, IL-12 p40, and inducible nitric oxide synthetase 2 (NOS2) mRNA in their lungs, implicating inducible NOS as a defense mechanism in this disease. We treated DBA/2 mice with aminoguanidine, and they became more susceptible to C. immitis peritonitis and pneumonia. We conclude that high levels of IL-10 are both necessary and sufficient to make mice susceptible to C. immitis, regardless of the genetic background of the mice, and that IL-10 impairs resistance to C. immitis in part by suppressing NO synthesis.

Neumatosis cystoides intestinal: reporte de un caso / Pneumatosis cystoides intestinalis: report of a case

La neumatosis intestinal también denominada enfisema buloso, quistes abdominales con gas y neumatosis cystoides intestinal, es una afección poco frecuente. En los registros de sistemas automatizados de información se encontraron 44 artículos publicados en los últimos 3 años a nivel mundial, con excepción de los paises latinoamericanos, los cuales no están incluídos. En los paises latinoamericanos se han publicado 10 articulos desde el año 1981 a 1994. A nivel nacional no se encontró ningún artículo publicado de neumatosis quística intestinal, en los últimos 14 años. Se presenta el caso de un paciente masculino de 44 años de edad con cuadro clínico de abdomen agudo por ulcus péptico perforado, encontrando neumatosis quística intestinal como hallazgo casual en la laparotomía exploradora. El paciente evolucionó satisfactoriamente en el postoperatorio

Factores genéticos y su influencia en las micosis sistémicas / Genetic factors and their influence in systemic micoses

La respuesta defensora del hospedero frente a la infección microbiana depende de múltiples mecanismos, entre los cuales las características genéticas del hospedero juegan papel importante, ya que condicionan tanto la resistencia natural como la adquirida. La mayoría de hallazgos en este campo en micosis sistémicas, se ha evidenciado en el modelo animal. En estas enfermedades, uno de los componentes genéticos más estudiados ha sido el complejo mayor de histocompatibilidad (CMH). Sin embargo, en ratones consaguíneos no se ha demostrado la existencia de una relación entre estos genes y la respuesta inmune desencadenada contra los agentes causales de tales micosis. Con relación a otros factores, como el sistema del complemento, se ha podido establecer una asociación solamente en el caso de la criptocosis. En cepas consanguíneas de ratón, los patrones de resistencia y susceptibilidad a Cryptococcus neoformans dependen de la presencia o ausencia del gen correspondiente, C superíndice 1 o Cº, repectivamente. Por otra parte, en un buen número de las micosis que se mencionan, se ha demostrado que la respuesta inmune mediada por células, es fundamental para su control. En la coccidioidomicosis y la paracoccidioidomicosis, la función de las células T es decisiva, a diferencia de lo observado en candidiasis, en la cual la principal célula efectora parece ser el polimorfonuclear. En cuanto al patrón de citocinas, se ha observado que los ratones suscptibles a Coccidioides immitis o Paracoccidioides brasiliensis, al ser infectados con estos hongos, producen predominante y tempranamente citocinas tipo TH2, IL-10 e IL-4 en coccidioidomicosis e IL-10 e IL-5 en paracoccidioidomicosis. En la histoplasmosis, los estudios han señalado la importancia del IFN gamma en la defensa. Hasta el presente, sólo se conocen genes específicos que determinan la respuesta inmune en la candidiasis, Carg1 y Carg2. En la coccidioidomicosis, se han sugerido dos genes, Cms1 y Cms2. En las micosis que se describen a continuación, el gen o los genes que condicionarían la respuesta correspondene son de tipo autosómico y el fenotipo de resistencia es el dominante. En esta revisión se analizan ciertos aspectos de la constitución genética del hospedero que condcionan la respuesta inmune frente a los agentes causales de las micosis sistémicas y se señalan las similitudes y las diferencias entre ellos

Actividades de enfermeria realizadas en pacientes con enfermedad cerebrovascular en el Hospital Regional San Juan de Dios de Zipaquira del 1 al 31 de diciembre de 1985 / Nursing activities performed in patients with cerebrovascular disease in Hospital Regional San Juan de Dios. Zipaquira 1-31 december, 1985

Durante el mes de diciembre de 1985 se observaron y registraron en el formato previamente disenado para ello. Las actividades realizadas por el personal de enfermeria a 7 pacientes con diagnostico de A.C.V. durante el turno de la noche en el Hospital San Juan de Dios de Zipaquira. El analisis de los datos recolectados demuestra que la enfermedad vascular cerebral afecta principalmente al sexo masculino entre 51 y 60 anos, a cada una de las actividades de enfermeria registradas se le dio un puntaje entre 5 y 15 por relevancia para valorar el indice de cumplimiento (tabla 5) dentro de ellas figuran: comunicacion, control de signos vitales, control de signos neurologicos, mantenimiento de la via aerea permeable, control de liquidos, fomento de la comodidad, rehabilitacion, higiene, administracion de drogas, asistencia en la alimentacion, informacion sobre el paciente y se observo un 76.5% de cumplimiento. El incumplimiento de las actividades de enfermeria depende de falta de personal (1 auxiliar/19 pacientes), falta la informacion del personal respecto al cuidado del paciente, carencia de recursos, ubicacion de los pacientes en el servicio y falta de una hoja de control neurologica adecuada..
