Aportes para el abordaje de la salud de las y los adolescentes como sujeto de derechos desde una mirada antropológica / Contributions to address the health of adolescents as rights holders from an anthropological perspective

Este artículo se propone reflexionar en torno al reconocimiento de la condición jurídica de las y los adolescentes como sujeto de derechos en los procesos de atención de la salud de esta población. A partir de la autonomía progresiva y la participación directa entendidos como dos principios rectores de la Convención sobre los Derechos del Niño (CDN), se realiza un contrapunto entre las definiciones presentes en la política de salud en la adolescencia y las prácticas y sentidos puestos en juego por las/os profesionales de la salud. Las reflexiones se basan en el análisis de materiales etnográficos, producidos en una investigación realizada en la ciudad de Bahía Blanca, desde una perspectiva antropológica, centrada en la definición social de las edades. Para cerrar, se plantea una síntesis de algunos aspectos con el propósito de contribuir a la problematización de las nociones de adolescencia desde las cuales se brinda atención sanitaria de esta población. Y de favorecer el abordaje de la salud de las y los adolescentes como sujeto de derechos (AU)

This article aims to reflect on the recognition of the legal status of adolescents as subject of rights in the health care processes of this population. Starting from progressive autonomy and direct participation understood as two guiding principles of the Children's Rights Convention (CRC), a counterpoint is made between the definitions present in health policy in adolescence and the practices and meanings put into play by the health professionals. The reflections are based on the analysis of ethnographic materials, produced in an investigation carried out in the city of Bahía Blanca, from an anthropological perspective, focused on the social definition of ages. To close, a synthesis of some aspects is proposed with the purpose of contributing to the problematization of the notions of adolescence from which health care is provided to this population. And to promote the approach to adolescent health as a subject of rights (AU)

Evaluation of oxidative damage and genotoxicity in populations exposed to arsenic in drinking water from Santa Fe province, Argentina.

The presence of arsenic in the environment is a public health problem. Groundwater of certain regions of Argentina contains arsenic of natural origin in concentrations that exceed the guide level recommended by World Health Organization (WHO, 10 µg/L). Pathologies derived from chronic arsenic consumption justify the planning of human biomonitoring. Hence, the aim of this study was to evaluate oxidative damage and genotoxicity and its relationship with nutritional variables in populations exposed to arsenic through drinking water in Santa Fe province, Argentina. A total of 322 participants were analyzed for arsenic in urine together with biomarkers of genotoxicity (Comet assay in blood and frequency of Micronuclei and other Nuclear Abnormalities in exfoliated buccal cells) and oxidative stress (modified Comet assay with Endonuclease III, Lipid peroxidation and antioxidant enzyme activity), as well as nutritional and biochemical variables. Results showed that 45 % of participants excreted arsenic in the urine. Consumption of water with arsenic, whether currently or previously, was associated with statistically significant increase of oxidative DNA damage and lipid peroxidation. MN in exfoliated buccal cells serve as an early biomarker of genotoxicity and showed significant differences in the current exposed group. Biochemical results indicate dyslipidemias potentially linked to dietary choices, and insufficient intake of fruits and vegetables rich in antioxidants, was also noted. This study advocates risk communication to the population, educators, and health authorities, emphasizing the need for preventive health strategies and improved food education.

A two-years real-word study with fingolimod: early predictors of efficacy and an association between EBNA-1 IgG titers and multiple sclerosis progression.

Background: Although fingolimod, a sphingosine 1-phosphate receptor agonist, has shown to be an effective treatment reducing relapse rate and also slowing down the disability progression in relapsing-remitting multiple sclerosis (RRMS) patients, it is important to quickly identify those suboptimal responders. Objective: The main objective was to assess different clinical, radiological, genetic and environmental factors as possible early predictors of response in MS patients treated with fingolimod for 24 months. The secondary objective was to analyze the possible contribution of the environmental factors analyzed to the progression and activity of the disease along the 2-years of follow-up. Methods: A retrospective study with 151 patients diagnosed with MS, under fingolimod treatment for 24 months, with serum samples at initiation and six months later, and with clinical and radiological data at initiation and 24 months later, were included in the study. Clinical and radiological variables were collected to establish NEDA-3 (no evidence of disease activity: patients without relapses, disability progression and new T2 lesions or Gd+ lesions) and EDA (evidence of disease activity: patients with relapses and/or progression and/or new T2 lesions or gadolinium-positive [Gd+] lesions) conditions. Human leukocyte antigen II (HLA-II), EBNA-1 IgG and VCA IgG from Epstein-Barr virus (EBV) and antibody titers against Human herpesvirus 6A/B (HHV-6A/B) were also analyzed. Results: A total of 151 MS patients fulfilled the inclusion criteria: 27.8% was NEDA-3 (37.5% among those previously treated with high efficacy therapies >24 months). The following early predictors were statistically significantly associated with NEDA-3 condition: sex (male; p=0.002), age at baseline (older; p=0.009), relapses 2-years before fingolimod initiation ≤1 (p=0.010), and absence of Gd+ lesions at baseline (p=0.006). Regarding the possible contribution of the environmental factors included in the study to the activity or the progression of the disease, we only found that EBNA-1 IgG titers decreased in 20.0% of PIRA (progression independent from relapse activity) patients vs. 73.3% of RAW (relapse-associated worsening) patients (p=0.006; O.R. = 11.0). Conclusion: MS patients that are male, older, and with a low clinical and radiological activity at fingolimod initiation have a greater probability to reach NEDA-3 condition after two years with this therapy. An intriguing association of EBV with the progression of the disease has also been described, but it should be further study in a larger cohort to confirm these results.

Programa de vacunación en prisiones: impacto del virus SARS-CoV-2 y retos de futuro / Prison vaccination programmes: the impact of the SARS-CoV-2 virus and future challenges

La vacunación ha sido tradicionalmente una de las actividades de prevención primaria a la que mayor esfuerzo se ha dedicado en las instituciones penitenciarias españolas. Una vez más, la pandemia de coronavirus de tipo 2 causante del síndrome respiratorio agudo severo (SARS-CoV-2) ha puesto de manifiesto la importancia de la vacunación en el control de las enfermedades inmunoprevenibles. Tras superar la emergencia sanitaria provocada por la enfermedad del coronavirus de 2019 (COVID-19), tenemos por delante el reto de recuperar las coberturas vacunales que teníamos antes de la pandemia, además de aumentar las de otras vacunas con menor implantación en nuestro medio. Entre las estrategias de mejora que se deben implementar, estaría la optimización de la transmisión de la información sanitaria entre centros penitenciarios dependientes de diferentes administraciones. También sería deseable poder acceder a los sistemas de información sobre vacunas de las diferentes comunidades autónomas, tanto para conocer el estado vacunal de los pacientes como para notificar las dosis administradas durante el periodo de internamiento, así como mejorar las estadísticas vacunales disponibles en prisión.(AU)

Vaccination has traditionally been one of the primary prevention activities to which most effort has been devoted in Spanish penitentiary institutions. Once again, the type 2 coronavirus pandemic causing severe acute respiratory syndrome (SARS-CoV-2) pandemic has highlighted the importance of vaccination in the control of immunopreventable diseases.After overcoming the health emergency caused by the coronavirus disease 2019 (COVID-19), we face the challenge of recovering the vaccination coverage we had before the pandemic, in addition to increasing the coverage of other vaccines with lesser implantation in our environment. Among the improvement strategies to be implemented would be the optimization of the transmission of health information between penitentiary centers dependent on different administrations. It would also be desirable to be able to access the vaccine information systems of the different autonomous communities, both to know the vaccination status of patients and to report the doses administered during the period of internment, as well as to improve the vaccine statistics available in prison.(AU)

Differences in Colorectal Cancer Survival Based on Primary Tumor Location: Retrospective Study from a Single Institution.

Objective: The location of the primary tumor in colorectal cancer (CRC) could be a prognostic factor related to survival. However, its usefulness has not been sufficiently analyzed. The results in patients with tumors in initial stages are very limited, and there are descriptive parameters of survival that have not been analyzed in detail. In this study, the relationship between primary tumor location and survival in CRC patients was analyzed. Materials And Methods: This was a retrospective observational study. All patients treated consecutively for CRC between January 2005 and December 2019 in the same hospital center were included. Overall survival (OS), cancer-related survival (CRS), time to recurrence (TTR), relapse-free survival (RFS) and postrecurrence survival (PRS) were analyzed, and the results were classified by tumor stage. The results were compared among patients with right colon (RS), left colon (LS) and rectal tumors. Results: In the entire cohort, patients with RS tumors had lower OS and lower CRS at 60 months after diagnosis than did patients with LS or rectal tumors. In the regression analysis, the localization of the primary tumor was an independent prognostic indicator for OS and CRS. Analysis by tumor stage showed that patients with RS stage III tumors had lower OS and lower CRS at 60 months than did patients with LS and rectal tumors (42%, 59% and 53%, respectively, p = 0.006; and 48%, 63% and 57%, respectively, p = 0.025). Additionally, patients with RS Stage IV tumors had lower OS and lower CRS at 36 months than did patients with LS and rectal tumors (9%, 24%, 24%, respectively, p < 0.001; and 10%, 24% and 24%, respectively, p < 0.001). No differences were found in TTR and RFS among patients with stage I and II RS, LS, and rectal tumors. In contrast, patients with stage RS III tumors had significantly poorer PRS (9% for RS tumors, 13% for LS tumors, and 22% for rectal tumors) (p < 0.001). Conclusion: The location of the primary tumor in patients with CRC is related to survival. The effect of laterality is more marked in patients with stage III and IV tumors. Patients with RS tumors had lower OS and CRS due to the lower survival of patients with stage IV RS tumors and lower PRS for patients with stage III tumors.

Pharmacogenetics of taxane-induced neurotoxicity in breast cancer: Systematic review and meta-analysis.

Taxane-based chemotherapy regimens are used as first-line treatment for breast cancer. Neurotoxicity, mainly taxane-induced peripheral neuropathy (TIPN), remains the most important dose-limiting adverse event. Multiple genes may be associated with TIPN; however, the strength and direction of the association remain unclear. For this reason, we systematically reviewed observational studies of TIPN pharmacogenetic markers in breast cancer treatment. We conducted a systematic search of terms alluding to breast cancer, genetic markers, taxanes, and neurotoxicity in Ovid, ProQuest, PubMed, Scopus, Virtual Health, and Web of Science. We assessed the quality of evidence and bias profile. We extracted relevant variables and effect measures. Whenever possible, we performed random-effects gene meta-analyses and examined interstudy heterogeneity with meta-regression models and subgroup analyses. This study follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and STrengthening the REporting of Genetic Association Studies (STREGA) reporting guidance. A total of 42 studies with 19,431 participants were included. These evaluated 262 single-nucleotide polymorphisms (SNPs) across 121 genes. We conducted meta-analyses on 23 genes with 60 SNPs (19 studies and 6246 participants). Thirteen individual SNPs (ABCB1-rs2032582, ABCB1-rs3213619, BCL6/-rs1903216, /CAND1-rs17781082, CYP1B1-rs1056836, CYP2C8-rs10509681, CYP2C8-rs11572080, EPHA5-rs7349683, EPHA6-rs301927, FZD3-rs7001034, GSTP1-rs1138272, TUBB2A-rs9501929, and XKR4-rs4737264) and the overall SNPs' effect in four genes (CYP3A4, EphA5, GSTP1, and SLCO1B1) were statistically significantly associated with TIPN through meta-analysis. In conclusion, through systematic review and meta-analysis, we found that polymorphisms, and particularly 13 SNPs, are associated with TIPN, suggesting that genetics does play a role in interindividual predisposition. Further studies could potentially use these findings to develop individual risk profiles and guide decision making.

Role of Daratumumab in Combination With Standard Therapies in Patients With Relapsed and Refractory Multiple Myeloma.

Multiple myeloma (MM) is a hematological malignancy characterized by renal insufficiency, bone lesions, anemia, and hypercalcemia. In this modern era of medicine, even with the development of drugs like immunomodulatory agents (IMiDs) and proteasome inhibitors (PI), the treatment of MM prevails as a challenge. However, even after the attainment of total remission, relapse of MM and disease progression is frequent. That is why there is an urgent requirement to develop novel monoclonal antibody drugs. The latest drugs for the treatment of relapsed and refractory MM (RRMM) approved by the Food and Drug Administration (FDA) are elotuzumab and daratumumab. In this article, we will discuss daratumumab with different combination therapies. The literature exploration was done using PubMed, Medline, PubMed Central, and Research Gate. Keywords used to search are monoclonal antibodies, daratumumab, RRMM, and novel agents. Our review article, which includes 21 relevant articles, demonstrated that daratumumab in different combinations showed significant progression-free survival (PFS) without severe safety concerns. However, while observing all the studies, neither of them studied the combination therapies of daratumumab in end-stage renal disease (ESRD) patients. Hence, more randomized controlled clinical trials should be done to understand and compare the effect of the combination of daratumumab with the standard of care therapies in ESRD patients.

"Nosotros, los del medio". Cuando lo normal no constituye la regla. Una mirada antropológica acerca de la adolescencia / We ¨in the middle¨, when normal is not the rule. An anthropological look at adolescence

Introducción: Considerando que la adolescencia no constituye un período natural de la existencia humana sino que se trata de una categoría construida socialmente proponemos indagar los significados acerca del curso de la vida humana desde la mirada de los y las jóvenes. Objetivos: Caracterizar las representaciones sociales en torno a adolescencia entre jóvenes residentes del sector Villa Harding Green, Bahía Blanca, desde una mirada antropológica centrada en la construcción social del curso de la vida y de la adolescencia. Materiales y Métodos: La metodología seleccionada es de corte cualitativa, centrada en un enfoque etnográfico. Respecto a las técnicas de recopilación de información se usaron de manera combinada entrevistas semi-estructuradas, observación con distintos grados de participación y estructuración y uso de soportes gráficos. El análisis e interpretación de la información recopilada se apoya en los postulados de la Semiótica de Enunciados. Resultados: Las experiencias de vida de jóvenes de ambos sexos contrastan con la concepción acerca del curso de la vida en términos de una secuencia evolutiva unilineal. Se destaca la categoría nativa "medio" para auto-referenciarse, en detrimento de "adolescencia": ni grandes ni chicos. Es decir, ni una cosa, ni la otra; o "todo junto" y, al mismo tiempo. Conclusiones: Procuramos contribuir a la problematización de la noción de adolescencia, a través de la noción de alteridad o diversidad. Y esperamos que la mirada en torno a la alteridad y las distintas dimensiones que se conjugan en ella sirvan de insumo para pensar las distintas intervenciones en salud en relación a las adolescencias.

Introduction: OIntroduction: Considering that adolescence does not constitute a natural period of human existence but rather a socially constructed category, we propose to investigate the meanings about the course of human life from the perspective of young people. Objectives: To characterize the social representations about adolescence of young residents in Villa Harding Green neighborhood, Bahía Blanca, from an anthropological perspective, which accounts for the social construction of adolescence and otherness. Materials and methods: The selected methodology is qualitative, centered on an ethnographic approach. Regarding the information gathering techniques, semi-structured interviews, observation with different degrees of participation and structuring and use of graphic supports were used in a combined way. The analysis and interpretation of the information collected is supported by the postulates of the Semiotics of Statements. Results: The life experiences of young people of both sexes contrast with the conception about the course of life in terms of a unilinear evolutionary sequence. The native category "medium" (middle) stands out for self-referencing, to the detriment of "adolescence": neither old nor young. That is to say, neither one thing nor the other; or "all together" and at the same time. Conclusions: We seek to contribute to the problematization of the notion of adolescence, through the notion of otherness. And we hope that the view on otherness and the different dimensions that come together in it will serve as an input to think about the different health interventions in relation to adolescents.

Essential Genes to Consider in Epstein-Barr Virus-Associated Gastric Cancer: A Systematic Review.

Gastric cancer (GC) is a prevalent malignancy worldwide; the Epstein-Barr Virus (EBV) also affects many people worldwide. An important association has been seen in these two diseases that could explain causality and a possible viral etiology of GC as has been seen with Helicobacter pylori. This study aims to identify genes expressed in malignant cells that are infected with EBV and see if one could be more oncogenic than the other. We conducted a systematic review based on the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. We had 29 observational studies after inclusion/exclusion criteria and quality assessment for every single study. A total of 1022 patients were evaluated for different types of genes in 29 papers. It was demonstrated that the most expressed genes or the gene most involved were genes that are seen in Epstein-Barr virus-associated gastric cancer (EBVaGC) as latent genes of the EBV-infected cells, which are found in tumor cells. The genes that were mostly involved were LMP2, BNLF2a, and the absence of LMP1 that lead to the expression of BARF1, among other genes. These studies were made on mostly Asian populations, so it is still unknown if these genes involved have a geographical association more than an EBV and GC association.

Comparing the Role of the p53 Gene and Telomerase Enzyme in 'Accelerated Aging Due to Cancer': A Literature Review.

Aging is defined as progressive physiological alterations in an organism that lead to senescence. In response to stress, when proliferative-competent cells undergo permanent, irreversible growth arrest (like replicative dividing limit, oncogene activation, oxidative stress, or deoxyribonucleic acid (DNA) damage), it is termed as cellular senescence. Biomarkers p53, telomerase, and other inflammatory cytokines have a vital link with senescence, and directed use of these markers might be useful in manipulating cancer and the aging process. We included studies related to topics ' accelerated aging due to cancer', telomerase's relation to Aging and Cancer, p53's relation to Aging and Cancer, Atherosclerosis and Cancer from Search databases like PubMed and Google Scholar. We relied on peer-reviewed articles and included literature from the last 10 years written in the English language. Degenerative diseases in humans are usually linked to atherosclerosis, and atherosclerosis is associated with short leukocyte telomere length. Cancer itself and its treatment are linked with accelerated aging by causing progressive shortening of telomeres during cell replication, resulting in cell death. Gene p53 is known to have a dual effect that works as a tumor suppressor and has pro-aging side effects. In experimental studies, when p53 overcomes multiple regulatory mechanisms controlling its activity, then only the pro-aging side effects of p53 manifested. This might be a potential key for treating cancer without causing the side-effects of aging. In this review, we aim to explain and summarize the interdependent nature of p53, telomeres, and other conventional mechanisms of aging and cancer like inflammation, oxidative stress, uncontrolled proliferation, angiogenesis, micro ribonucleic acids (RNAs), and apoptosis, with a more synergistic approach that can help in developing new therapeutics and play a potential role in shaping modern human lifespan and revolutionize cancer treatment.

Current Treatment Modalities for Calcified Coronary Artery Disease: A Review Article Comparing Novel Intravascular Lithotripsy and Traditional Rotational Atherectomy.

The coronary artery calcium score is considered the most useful marker for predicting coronary events. The high score reflects heavy calcification in the vessel, which is more challenging to treat with the percutaneous intervention (PCI). To prepare this type of heavily calcified lesion intravascular lithotripsy (IVL) technology can be used prior to PCI, which is based on the concept of converting electrical energy into mechanical energy. It harmlessly and selectively disrupts both the shallow and deep deposits of calcium. The balloon-based catheters of this system emit sonic waves that transfer to the adjacent tissue resulting in improvement in vessel compliance with the slightest soft tissue loss. Therefore, making the treatment of calcified lesions more feasible, effective, and also simplify complex lesions. The lesions considered for lithotripsy-enhanced balloon dilation include calcified coronary lesions and peripheral vasculature lesions. This article reviews the use of IVL in calcified coronary artery disease, its advantages, and disadvantages while comparing it with other techniques like high-pressure balloons and rotational atherectomy devices. A thorough search of databases like PubMed and Google Scholar was performed, which uncovered 35 peer review articles. Keywords utilized in the data search were calcified coronary artery disease, coronary lithotripsy, calcification, and calcified atherosclerotic plaque. According to rotational atherectomy and intravascular lithotripsy trials, the latter was safer, mainly by decreasing atheromatous embolization risk. Deciphering these studies, it seems like IVL is better at parameters like procedural and clinical success rate, acute lumen gain, and less residual stenosis except in-hospital major adverse cardiovascular events (MACE), which was better in rotational atherectomy (RA). However, when lesion crossings are present, the atherectomy technique is still considered as first-line therapy. In clinical practice, despite these encouraging data for treating calcified lesions, IVL is grossly underutilized because of substantial costs and perceived significant procedural risk effects on the cardiac rhythm like causing 'shock topics' and asynchronous cardiac pacing. More longer-term clinical data and extensive researches are required to validate its safety and efficiency.

Recomendaciones para la evaluación del tamaño al nacer y del crecimiento posnatal de los recién nacidos prematuros / Recommendations for the assessment of birth size and postnatal growth of preterm newborns

Es innegable la necesidad de contar con curvas estándar de tamaño al nacer y crecimiento para evaluar y contribuir a orientar las acciones en la atención del neonato. Durante muchos años, se utilizaron las referencias de Lejarraga y Fustiñana, que fueron progresivamente reemplazadas por las de Fenton y Kim.Recientemente, el proyecto INTERGROWTH-21st construyó estándares de crecimiento prescriptivo para evaluar el tamaño al nacer desde las 33 semanas de edad gestacional, referencias para evaluar el tamaño al nacer desde las 24 a las 32,6 semanas de edad gestacional y curvas para el seguimiento longitudinal del crecimiento de recién nacidos pretérmino desde las 27 semanas de edad gestacional. Los Comités de Crecimiento y Desarrollo y de Estudios Feto-neonatales de la Sociedad Argentina de Pediatría, en conjunto con la Secretaría de Gobierno de Salud de la Nación, acordaron recomendar el reemplazo de las curvas de Fenton y Kim por las de INTERGROWTH-21st

It is unquestionable the need to have standards of size at birth and growth to evaluate and contribute to guide the actions in the care of the newborn. For many years the references of Lejarraga and Fustiñana were used, progressively replaced by those of Fenton and Kim. However, recently, the INTERGROWTH-21st project has developed prescriptive growth standards to evaluate the size at birth from 33 weeks of gestational age, references from 24 to 32.6 weeks of gestational age, and curves for postnatal growth from 27 weeks of gestational age onward. The Growth and Development and Neonatal Fetal Studies Committees of the Argentine Society of Pediatrics in conjunction with the Secretary of National Government of Health agreed to recommend the replacement of the Fenton and Kim curves with those of INTERGROWTH-21st.

Formación médica integral en espacios hospitalarios de la carrera de medicina en la Universidad Nacional del Sur. Enfoque desde la antropología de la salud. / Comprehensive medical education in hospital facilities for the medical program at Universidad Nacional del Sur. An approach from health anthropology

Introducción: El diseño curricular de la Carrera de Medicina de la Universidad Nacional del Sur (UNS) se implementa en la consideración del hombre como unidad bio-psico-socio-cultural. Consideramos que la mirada antropológica cobra protagonismo en este tipo de formación médica, de manera tal que los contenidos curriculares de la carrera integran conceptos teóricos de la subdisciplina Antropología de la Salud. Se propone verificar si tales conceptos brindados en el Ciclo Inicial son retomados en el Ciclo Profesional. Objetivo: caracterizar cómo se construye el ser humano, el proceso diagnóstico y la diagramación de tratamientos en las rotaciones médicas durante el Ciclo de Desarrollo Profesional de la Carrera de Medicina. Materiales y Métodos: La investigación es de tipo cualitativo. Las Unidades Educacionales son los espacios de aprendizaje en las Rotaciones de clínica, pediatría y ginecología del cuanto año del Ciclo Profesional, donde se analiza la dinámica entre estudiantes y docentes tutores, mediante técnicas de observación etnográficas y técnicas de análisis discursivo. Resultado: En el espacio de aprendizaje la persona es representada como el locus de la enfermedad más que como agente narrativo, y el diagnóstico como un saber objetivado, omitiéndose, en general, las referencias sociales que rodearon su constitución. Conclusiones: Los resultados preliminares confirman que los contenidos de Antropología de la Salud desarrollados en el Ciclo Inicial, no son retomados en el Ciclo Profesional, cuando el estudiante se enfrenta al abordaje del caso real en el ámbito hospitalario. Por tanto desde esta sub-disciplina no podemos confirmar que el abordaje de los casos reales se desarrolle de manera integral.

Introduction: the curricular design of the Medical Program at Universidad Nacional del Sur (UNS) has been implemented considering the individual as a bio-psychosocio-cultural unit. We believe that the anthropologic view is highly relevant in this type of medical education, so that the curricular contents in the program include theoretical concepts from the sub-discipline Health Anthropology. We propose to verify if such concepts given at the Initial Cycle are later considered in the Professional Cycle. Objectives: to characterize how the human being is constructed, the diagnosis process and the design of treatments in medical rotations during the Professional Development Cycle in the Medical Program. Materials and Methods: this is a qualitative research. Educational Units are the learning spaces in clinical, pediatric, and gynecologic rotations in the fourth year of the Professional Cycle, in which the dynamics between students and tutor professors is analyzed by means of ethnographic observation and discourse analysis techniques. Results: in the learning space, the individual is represented as the locus of the disease more than as a narrative agent and the diagnosis as an objective knowledge, thus omitting, in general, the social references that surrounded the individual's constitution. Conclusions: preliminary results confirm that the contents of the course Health Anthropology developed in the Initial Cycle are not reintroduced in the Professional Cycle, when the student is faced with the approach to the real case in the hospital environment. Therefore, from this sub-discipline we are not able to confirm that the approach to real cases is done in a comprehensive way.

Resultados del Programa Nacional de Prevención de la Ceguera en la Infancia por Retinopatía del Prematuro en Argentina (2004-2016) / Results of the National Program for the Prevention of Blindness in Childhood by Retinopathy of Prematurity in Argentina (2004-2016)

Introducción. El Grupo ROP Argentina,a cargo del "Programa Nacional para la Prevención de la Ceguera en la Infancia por Retinopatía del Prematuro" (ROP), se creó en 2003. Objetivos. Describir la implementación y resultados alcanzados por el programa en la efectividad, acceso y calidad en la atención de la ROP (2004-2016). Población y métodos. Estudio descriptivo, retrospectivo, de una cohorte dinámica, en instituciones adheridas al registro. Población elegible: la totalidad de recién nacidos prematuros con factores de riesgo para desarrollar ROP. Resultados. Los servicios incorporados aumentaron de 14 a 98; cubrieron 24 provincias. Los niños < 1500 g registrados en 2004fueron 956, y 2739 en 2016. El 22,7 % de estos presentó algún grado de ROP y el 7,8 % requirió tratamiento (ROP grave). La pesquisa superó el 90 % y aumentaron los tratamientos en el lugar de origen (57 %-92 %). La incidencia de casos inusuales sigue siendo elevada (17,3 % de los tratados) y aún se registran oportunidades perdidas. El uso de drogas antiangiogénicas se triplicó desde su inicio en 2011. Conclusiones. Se observan logros significativos en términos de representatividad, alcance y adherencia al programa, también en el acceso a la pesquisa y tratamiento en el lugar de origen; sin embargo, la incidencia de ROP es aún elevada. La subraya la necesidad de fortalecer aún más las acciones del programa en cuanto a servicios.

Introduction. The ROP Argentina Group was created in 2003 and is responsible for the National Program for the Prevention of Blindness in Childhood by Retinopathy of Prematurity (ROP) in Argentina. Objectives. To describe the program implementation and results achieved in relation to ROP care in terms of effectiveness, access, and quality (2004-2016). Population and methods. Descriptive, retrospective study with a dynamic cohort carried out in facilities that are part of the registry. Eligible population: All preterm newborn infants with risk factors for ROP. Results. Participating health care services increased from 14 to 98 and covered the 23 provinces and the Autonomous City of Buenos Aires. A total of 956 infants were born with < 1500 g in 2004 and 2739, in 2016. Of these, 22.7 % had some degree of ROP and 7.8 % required treatment (severe ROP). Vision screening exceeded 90 %, and treatments at the place of origin increased (57 %-92 %). The incidence of unusual cases is still high (17.3 % of treated cases), and missed opportunities are still recorded. The use of anti-angiogenic drugs trebled since 2011, when they started to be used. Conclusions. Significant achievements were observed in terms of program representativeness, scope, and adherence, and also in relation to screening access and treatment at the place of origin; however, the incidence of ROP is still high. The persistence of unusual cases and missed opportunities evidences deficiencies in the quality of health care and outpatient followup and underlines the need to strengthen the program actions in relation to services.

CONCLUSIONS: Significant achievements were observed in terms of program representativeness, scope, and adherence, and also in relation to screening access and treatment at the place of origin; however, the incidence of ROP is still high. The persistence of unusual cases and missed opportunities evidences deficiencies in the quality of health care and outpatient followup and underlines the need to strengthen the program actions in relation to services.

Introducción. El Grupo ROP Argentina,a cargo del "Programa Nacional para la Prevención de la Ceguera en la Infancia por Retinopatía del Prematuro" (ROP), se creó en 2003. Objetivos. Describir la implementación y resultados alcanzados por el programa en la efectividad, acceso y calidad en la atención de la ROP (2004-2016). Población y métodos. Estudio descriptivo, retrospectivo, de una cohorte dinámica, en instituciones adheridas al registro. Población elegible: la totalidad de recién nacidos prematuros con factores de riesgo para desarrollar ROP. Resultados. Los servicios incorporados aumentaron de 14 a 98; cubrieron 24 provincias. Los niños < 1500 g registrados en 2004fueron 956, y 2739 en 2016. El 22,7 % de estos presentó algún grado de ROP y el 7,8 % requirió tratamiento (ROP grave). La pesquisa superó el 90 % y aumentaron los tratamientos en el lugar de origen (57 %-92 %). La incidencia de casos inusuales sigue siendo elevada (17,3 % de los tratados) y aún se registran oportunidades perdidas. El uso de drogas antiangiogénicas se triplicó desde su inicio en 2011. Conclusiones. Se observan logros significativos en términos de representatividad, alcance y adherencia al programa, también en el acceso a la pesquisa y tratamiento en el lugar de origen; sin embargo, la incidencia de ROP es aún elevada. La subraya la necesidad de fortalecer aún más las acciones del programa en cuanto a servicios.

Reducing Blindness from Retinopathy of Prematurity (ROP) in Argentina Through Collaboration, Advocacy and Policy Implementation.

Retinopathy of prematurity (ROP) is a largely avoidable cause of blindness in children worldwide, requiring high-quality neonatal care, early detection and treatment. In middle-income countries throughout Latin America, Eastern Europe and South Asia, there has been a rise in ROP blindness due to a combination of increased survival of preterm infants, resource-scarce medical environments and lack of policies, training and human resources. However, Argentina is an example of country where rates of ROP blindness have declined and ROP programmes have been successfully and effectively embedded within the health and legal system. The purpose of this study is to describe the activities and stakeholders, including Ministry of Health (MoH) and UNICEF, involved in the process, from recognition of an epidemic of ROP blindness to the development of national guidelines, policies and legislation for control. Using a retrospective mixed methods case study design, data on rates of severe ROP was collected from 13 neonatal intensive care units from 1999 to 2012, and on the proportion of children blind from ROP in nine blind schools in seven provinces. Legislative document review, focus group discussions and key informant interviews were conducted with neonatologists, ophthalmologists, neonatal nurses, parents, MoH officials, clinical societies, legislators and UNICEF officials in seven provinces. Results are presented combining the stages heuristic policy framework and Shiffman including: agenda setting, policy formulation, implementation and evaluation. By 2012, ROP had declined as a cause of blindness in children in schools for the blind as had rates of severe ROP needing treatment in the NICUs visited. Multiple factors played a role in reducing blindness from ROP in Argentina and successfully coordinating its control including national advocacy, leadership, legislation and international collaboration. Lessons learned in Argentina can potentially be scaled to other LMICs in Latin America and beyond with further context-specific research.

Acceso de las familias a las unidades de internación de Neonatología en Iberoamérica: una realidad a mejorar / Family access to Neonatal Intensive Care Units in Latin America: A reality to improve

INTRODUCCIÓN: El ingreso de la familia en UCIN trae beneficios al RN y su familia, como eje de la atención humanizada. OBJETIVO: Conocer el estado actual sobre acceso de padres y familias en UCIN de Iberoamérica. MÉTODOS: Estudio transversal en 15 países de Iberoamérica. Dos cuestionarios: 1) para enfermeros jefes con tareas de gestión y conducción, y 2) para enfermeros en tarea asistencial. Se exploró sobre características y modalidades de funcionamiento; uso de guías de acceso, opinión personal sobre derecho a ingresar, riesgos, interferencias o colaboración relacionadas al ingreso, y papel de enfermería en las decisiones. Líderes de enfermería de cada país identificaron contactos y obtuvieron autorización según regulaciones de cada país. Las repuestas fueron analizadas en forma centralizada sin identificación del participante. RESULTADOS: Seiscientos cuarenta cuestionarios; respuesta en 226 (35%). Entre 52 UCIN, el 63% dispone de lugar para estancia de madres (solo el 27% durante la noche); en el 31 (60%) existen carteles que indican sobre horarios fijos para «visitas» de padres. El ingreso irrestricto existe en solo 19 UCIN (36%); para hermanos y abuelos es más restringido (en el 29% no es posible). Entre las 174 enfermeras, el 76% considera que las madres deben acceder siempre, pero estos porcentajes disminuyen para padres, hermanos y abuelos; el 77% opina que enfermería favorece y el 35% que dificulta el acceso. Adicionalmente, el 48% opina que el ingreso interfiere con tareas de enfermería. CONCLUSIÓN: Es necesario un cambio cultural en las UCIN de Iberoamérica para que se respeten los derechos de los RN y sus familias durante la internación

INTRODUCTION: Family access to NICUs has benefits for the newborn (NB) and family, as the main way of humanised care. OBJECTIVE: To determine the current state of parents and families access to NICUs in Latin America. METHODS: A cross-sectional study was conducted in 15 countries using two questionnaires: 1) directed at head nurses with management and supervision activities, and 2) nurses with care tasks. The features and modes of functioning were examined; the use access guides, personal opinion on the rights to enter, risks, interference, or collaboration as regards the patient, and nursing role in decisions. Nursing leaders of each country identified contacts and obtained authorisation under the regulations of each country. The responses were analysed centrally with the participants remaining anonymous. RESULTS: Out of 640 questionnaires issued, responses were received by 226 (35%). Among 52 NICU, 63% have a place for mothers to stay (only 27% overnight), and in 31 (60%) there are notices with fixed schedules for visiting the NB. Unrestricted access exists in only 19 NICU (36%), but for siblings and grandparents it is more restricted (it is not possible in 29%). Among the 174 nurses that responded, 76% feel that mothers should always have access, but these percentages decrease for fathers, siblings and grandparents. A large majority (77%) believe that nursing staff would favour access, and 35% would make it difficult. In addition, 48% believed that access interferes with nursing care. care. CONCLUSION: A cultural change is needed in the NICUs in Latin America in order to respect the rights of newborns and their families during hospitalization

Exposición a arsénico en agua de bebida y asociación con cáncer y con ERC, genotoxicidad y daño neurocognitivo en Argentina / Exposure to arsenic in drinking water and association with cancer and CKD, genotoxicity and neurocognitive damage in Argentina

Se realizó un estudio ecológico con el objetivo evaluar la asociación entre los niveles de arsénico (As) en agua de bebida con la mortalidad por cáncer de piel, vejiga, pulmón, hígado y riñón y con la IN (IN) y prevalencia (PR) de enfermedad renal crónica de etiología desconocida (ERCd). Se construyó un mapa con datos de As en agua de 167 departamentos de la Argentina. Se analizó la asociación entre los valores de As en agua y las tasas de mortalidad por los distintos cánceres, y la IN y PR de ERCd, mediante la autocorrelación espacial I Moran, el modelo regresión de Poisson, la prueba de Kruskal Wallis y el modelo de regresión lineal. En localidades seleccionadas de dos provincias argentinas (Santa Fe y Jujuy) se realizaron sendos estudios transversales para investigar la asociación entre la exposición a As y el daño genético en adultos (mediante el conteo de micronúcleos y el ensayo cometa), y el daño neurocognitivo (mediante la aplicación de pruebas neuroconductuales) en niños y adultos. No se encontró asociación estadísticamente significativa entre la concentración de As en el agua y las tasas de mortalidad para ninguno de los cánceres estudiados, ni con la IN o la PR de ERCd. Solo para las tasas de mortalidad por cáncer de pulmón se observó una asociación marginal. Tampoco se observaron diferencias significativas entre los grupos control y tratamiento en cuanto al daño genético, ni para el daño neurocognitivo. Se concluye que la ausencia de asociación entre mortalidad por cánceres específicos y ERCd con los valores de As en el agua pudo deberse a que tanto la base de datos de As en agua, como la de la mortalidad por cánceres y la de ERCd no fueron lo suficientemente desagregadas como para encontrar asociación. En cuanto a los estudios transversales se propone profundizar el análisis, aumentando el número de individuos estudiados
