Resistencia antimicrobiana y producción porcina de cría intensiva / Antimicrobial resistance and intensive swine production: mini review

Introducción: el impacto de la resistencia antimicrobiana (RAM) generará un aumento de las muertes relacionadas de 10 millones anuales hacia 2050. El 70% de la dispensación de antimicrobianos (ATB) se utiliza en la agroveterinaria y no en salud humana. Es fundamental conocer la portación de RAM en trabajadores de cría de animales y en los animales, para acciones tempranas de salud pública. Métodos: bajo metodología PRISMA se realizó la búsqueda bibliográfica en distintas fuentes disponibles hasta octubre de 2020. Se priorizaron revisiones sistemáticas, metanálisis, ensayos clínicos y estudios observacionales para determinar la RAM en trabajadores de cría de cerdos. De 990 artículos identificados se incluyeron 8 estudios. Resultados: la tasa de colonización por Staphylococcus aureus resistente a la meticilina (SAMR) en trabajadores fue mayor que la de la población general. La prevalencia de SAMR fue significativamente mayor en trabajadores en contacto directo con animales y los de granjas de cría intensiva con respecto a los de extensiva. En cerdos, la prevalencia de RAM en cría intensiva fue significativamente mayor que la de los de cría extensiva. También fue significativa la asociación entre el suministro de antibióticos en la cría intensiva y la presencia de RAM. Las granjas de más de 1250 cerdos presentaron mayor prevalencia de RAM (p < 0,001). El fenotipo de SAMR en cerdos, trabajadores y el ambiente fue el mismo. Conclusiones: existe evidencia de asociación entre la producción agrícola de cría intensiva y la RAM en cerdos y trabajadores. No se encontraron estudios de vigilancia epidemiológica en la Argentina en trabajadores de cría de animales. (AU)

Introduction: it is estimated that the impact of antimicrobial resistance (AMR) will generate an increase of 10 million deaths by 2050, being reflected to a greater extent in low-income countries. 70% of the annual use of antimicrobials is concentrated in agroveterinary but not in human health. Considering the presence of AMR in ranchers and agricultural workers is essential for early public health actions. Methods: using the PRISMA methodology, bibliography was searched in different sources until October 2020. Systematic reviews, meta-analyses, clinical trials and observational studies were prioritized to determine AMR in pig workers. Eight studies of the 990 found have been included. Results: the rate of colonization by methicillin-resistant Staphylococcus aureus (MRSA) in farming workers was higher than the general population. MRSA prevalence was significantly higher in workers who reported direct contact with animals. And also in those workers of intensive farms compared to those of extensive farms. The same situation is observed in swines, in which the prevalence of AMR in intensive farming was significantly higher than in extensive farming. The association between the supply of antibiotics in intensive farming workers and the presence of AMR was also significant. Farms with more than 1,250 swines had a higher prevalence of AMR (p<0.001). The MRSA phenotype found in swine, agricultural workers, and the environment was the same. Conclusions: there is scientific evidence of an association between agricultural production in intensive livestock farming and AMR in swine and farming workers. There aren't Argentine studies of epidemiological surveillance in farming workers. (AU)

[Parental risk perception of 0-3-year-old children exposure to household pesticides]. / Percepción del riesgo de toxicidad por exposición a plaguicidas domésticos en hogares con niños de 0 a 3 años.

The objective of this work was to know the practices and risk perception of household pesticides (HPs) of mothers and fathers of children in early developmental stages. SUBJECTS AND METHOD: Quali tative research carried out in 2015. We conducted interviews in 18 homes with mothers and fathers of children aged 0 to 3 years registered in the General Health Insurance Plan of the Hospital Italiano de Buenos Aires (Metropolitan Area of Buenos Aires). The analytical categories were identified, interpre tive analytical categories of higher-level abstraction were conceptualized, and finally, diagrams were constructed to represent and organize the findings. RESULTS: The interviews showed that mothers and fathers: 1) used HPs regularly, 2) showed low concern for the health hazards of HPs and other hou sehold chemicals, except for a small, more sensitized group of parents, 3) they were more concerned regarding mosquito bites than exposure of their children to HPs, 4) relied on fumigation services and the normative framework that regulates them, and 5) expressed interest and willingness to receive more information and orientation from the pediatrician about the safe use of chemical products at home. Other analytical categories showed a constant parental adjustment between toxicity, patho genicity, hygiene, and well-being. CONCLUSIONS: Since home exposures levels to HPs considered safe for adults may be toxicologically relevant for young children, government and health agencies should provide parents with tools to decode HPs marketing and publicity messages, as well as to conceptua lize the relationship between HPs use and childhood health disorders.

Vigilancia epidemiológica de siniestros viales en un hospital privado de la Ciudad de Buenos Aires: año 2018 / Epidemiological surveillance of accidents in a private hospital in The City of Buenos Aires: year 2018

Introducción: los siniestros viales representan un significativo problema de salud pública y una de las principales causas de morbimortalidad evitables en la Argentina. La vigilancia epidemiológica permite valorar el alcance del problema y orientar respuestas. El objetivo de este estudio es describir las características demográficas, uso de la vía pública, mecanismo de producción, evaluación en Unidad de Emergencias y morbimortalidad de los casos ingresados en el sistema de vigilancia epidemiológica de siniestros viales en el Hospital Italiano de Buenos Aires durante durante el año 2018. Materiales y métodos: estudio observacional de corte transversal. Se analizaron las variables sexo, grupo etario, tiempo de internación, tipo de usuario, mecanismo de producción, gravedad del herido y del siniestro. Resultados: se registraron 404 consultas por siniestros viales. El sexo masculino fue el predominante en el 62,13% (251). El rango etario más frecuente abarcó los 25 a 44 años (187). La forma de traslado mayoritaria fue el automóvil en el 42,57% (172), seguido de motovehículos 29,21% (118). La gran mayoría fueron secundarios a colisiones entre dos vehículos. El 80,20% (324) ingresó deambulando por sus propios medios y el 83% (336) no requirió internación. El 90,6% (366) consultó por heridas leves. De los heridos graves, el 71,05% (27) fue de sexo masculino y el 26,32% (10) mayor de 75 años. La mayoría eran usuarios de automóvil. Ocurrieron 3 óbitos de mujeres mayores de 75 años. Conclusión: se observó una mayor cantidad de siniestros viales en adultos jóvenes, principalmente en varones. En general, usuarios de vehículos que consultaron tras una colisión con otro vehículo. Mayormente, ingresaron por sus propios medios, no requirieron internación de ningún tipo y presentaron heridas leves. Los casos graves correspondieron en su mayoría a varones con gran proporción de adultos mayores. Los casos fatales ocurrieron en mujeres adultas mayores. Contar con información del perfil epidemiológico de los siniestros viales permite la comprensión de esta compleja problemática en el ámbito local y el diseño de estrategias de intervención ajustadas a dicho perfil.

Introduction: road accidents represent a significant public health problem and one of the main causes of preventable morbidity and mortality in Argentina. Epidemiological surveillance makes it possible to assess the scope of the problem and guide responses. The objective of this study is to describe the demographic characteristics, use of the public highway, production mechanism, evaluation in the emergency center and morbidity and mortality of the cases admitted to the epidemiological surveillance system of road accidents at the Hospital Italiano de Buenos Aires during 2018. Materials and methods: observational cross-sectional study. The variables sex, age group, length of stay, type of user, production mechanism, severity of the injured and the accident were analyzed. Results: 404 consultations for road accidents were registered. Male sex was predominant in 62.13% (251). The most frequent age range was 25 to 44 years (187). The majority form of transportation was the automobile in 42.57% (172), followed by motorcycle vehicles 29.21% (118). The vast majority were secondary to collisions between two vehicles. 80.20% (324) were admitted wandering by their own means and 83% (336) did not require hospitalization. 90.6% (366) consulted for minor injuries. Of the seriously injured, 71.05% (27) were male and 26.32% (10) were older than 75 years. Most were car users. There were 3 deaths of women older than 75 years. Conclusion: there was a greater number of road accidents in young adults, mainly in men. In general, vehicle users consulted after a collision with another vehicle. Moreover, they entered by their own means, they did not require hospitalization of any kind and presentation of minor injuries. Severe cases correspond mostly to males with a large proportion of older adults. The fatal cases occurred in older adult women. Having information on the epidemiological profile of road accidents allows the understanding of this complex problem at the local level and the design of intervention strategies adjusted to this profile.

[Clinical research in internal medicine residencies in Argentina. Supporters and detractors]. / La investigación clínica en residencias de medicina interna de la Argentina. Facilitadores y barreras.

Several academic and government organizations have strongly recommended the inclusion of specific competences in clinical research. So far, the current state of research within this framework has not been modified in our country. The main goal of this study was to provide a thorough description of the research activities in medical residencies, which could be used as an indicator of the acquisition of such competences and to identify the supporters and detractors to achieve them. A cross section study was carried out and several levels were analyzed in order to consider residencies as a cluster; 382 residents from 24 different residencies were included. the study showed a preponderance of women. the average age was 29 years old. A 71% of the residents asserted doing research. Half of those residents have stated being authors of papers presented in congresses; only 9% have published their experience. Factors which predict the development of research assignments were: to belong to a large residency, oR 16.99 (IC 95%, 2.096-137.87), being in the 3rd year of the residency, oR 9.95 (IC 95%, 2.84-34.82), completion of a research course, oR 2.78 (IC 95%, 1.10-7.04). Variables which reduce the chance to do research: location in Buenos Aires, oR 0.25 (IC 95%, 0.0072-0.91), being a woman, oR 0.34 (IC 95%, 0.14-0.79) and patients assistance workload, OR 0.97 (IC 95%, 0.95-0.99). We believe that the identification of factors which influence the possibility of doing research will lead to a improvement in the training of medical residents.

[Gaps between prescription of anti-hypertensive and hypertension control in older adults of Buenos Aires suburbs]. / Brechas entre la prescripción de antihipertensivos y el control de la hipertensión en adultos mayores de los CAPS del conurbano bonaerense.

BACKGROUND: Medications delivered to primary care centers (PCC) all over the country through the Remediar program (RP) covers 80% of the most prevalent diseases. Among them, the prevalence of hypertension is 77% of 65 years or older. OBJECTIVE: To describe the pharmacological treatment and its appropriateness, and to understand needs and barriers among hypertensive beneficiaries of RP at Buenos Aires suburbs. Method Qualitative-quantitative triangulation: cross-sectional study with revision of medical records (MR) and in-depth interviews between December/2008 and February/2009 to hypertensive patients of 65 years or older and CAPS's staff. Prevalence of correct treatment (CT); appropriate Indication (AI); Optimal control (OC) were analyzed. RESULTS: The following PCCs were selected: Moreno, Tigre, Lomas de Zamora, Lanus and San Isidro. Prevalence of: CT: (10.2%; 95%CI 6,7-15,1); AI: (84.8%; 95% CI 80-89 ), and OC: 11,6% (95%CI 7-16) and OC among patients with good registry: 35.7% (95%CI 24,9-48,1). Eighty two % of patients received a prescription for enalapril. Deficient registry was detected in MR. Interviewees expressed difficulties in accessing treatment, lack of medication and use of alternative circuits to get them. Both, staff and patients were exposed to barriers generated by CAPSs and RP. CONCLUSIONS: A low degree of blood pressure control was observed, even with adequate prescription. Multifactorial problems explain several barriers to access and maintain hypertension treatment.

[Internal Medicine Residencies in Argentina, 2008]. / Formación en las residencias de clínica médica en la Argentina, 2008.

The acquisition of medical competence in the Internal Medicine Residencies (IMR) is a complex process. In Argentina there are not current data available on the number, organization and the way the residencies work. The objective of this study was to survey the IMR in Argentina and categorize their academic and general structure. From June 2007 to June 2008 we identified all the IMR using a combined searching strategy. We contacted them looking for structural and organizational data. Academic data were collected in a sample of 24 residencies using questionnaires. We also gathered data using qualitative measurements, in a subsample of 15 residencies, by means of direct observation and in-depth interviews. We identified 162 ongoing residencies and a total of 2012 residents. The majority of them (87%) were located in big cities, with a preponderance of public residencies (66%); 13% of these didn't have a residency instructor or coordinator. Most of these didn't have Institutional Internet available. The residents median age was 29 years old (Intercuartil range 2.7), with a 64.5% of women; 24% were under the regimen called "concurrente". From the sample, 230 residents were interviewed; 13% of them (CI95% 9-18.7) did not receive any remuneration. The rest received a monthly payment (in Arg $) ranging from US$ 140 to 552. A 58% (13/22) was involved in Specialist courses. Medians for weekly working hours and for "on duty" were respectively 50 and 8 per month, with no difference between public or private institutions. These findings evidence the need to certify the formative and academic process of IMR.

Formación en las residencias de clínica médica en la Argentina, 2008 / Internal Medicine residencies in Argentina, 2008

La adquisición de las competencias médicas de las Residencias de Clínica Médica (RCM) es un proceso complejo. En la Argentina no contamos con datos actualizados de su identificación, organización y funcionamiento. El objetivo del estudio fue censar las RCM de Argentina y caracterizar su estructura general y formativa. Entre junio 2007 y junio 2008 todas las instituciones con RCM del país fueron relevadas mediante estrategias de búsqueda, y contactadas para datos estructurales y de organización. Se recabaron datos académicos en una muestra de 24 residencias mediante cuestionarios, y en una submuestra de 15 con técnicas cualitativas de observación directa y entrevistas. Relevamos 162 RCM activas distribuidas en su mayoría (87%) en ciudades grandes y 2012 residentes. La mayoría pertenecen al sector público (66%). Un 13% no cuentan con coordinador o instructor y la mayoría no posee acceso a Internet institucional. Según el censo, la mediana de edad de los residentes es de 29 años (intervalo intercuartil 2.7), siendo 64.5% mujeres y 24% concurrentes. De los encuestados, 13% (IC 95% 9-18.7) refirió no recibir remuneración, en el resto la misma varió entre $520 y $ 2100 mensuales; 58% (13/22) realiza curso de especialista. Las medianas de horas trabajadas semanales y de guardias mensuales fueron 50 y 8 respectivamente, sin diferencias entre los centros públicos y privados. Estos hallazgos muestran la necesidad de reconsiderar la certificación del proceso formativo de las RCM.
