The role of registries in improving health and bridging healthcare, research, education, innovation and development: a research department perspective.

Health registries are organized systems that collect data on individuals with a particular disease, condition or exposure. The aim of this narrative review was to provide an integrated perspective from the Research Department at the Hospital Italiano de Buenos Aires, Argentina, on how health registries can be used as a bridge between healthcare, research, education, innovation and development while addressing ethical challenges. The review includes a description of the experience of a registry implemented at our institution, which has provided healthcare for 170 years, and is committed to support, education and research. We focus on the potential of health registries to provide better value healthcare by reducing healthcare costs and improving health outcomes and quality of care, and to improve medical knowledge. However, we also acknowledge and discuss the challenges that accompany these achievements, such as that of ethical issues. Through effective collaboration and integration with other healthcare stakeholders, health registries can be a powerful tool to promote better health.

[Epidemiology of patients with hepatocellular carcinoma in a University hospital]. / Epidemiología de pacientes con hepatocarcinoma en un Hospital Universitario.

Hepatocellular carcinoma is the most common primary liver tumor, with 905 677 diagnosed cases and 830 180 deaths, in 2020 worldwide. In Argentina, it accounts for the 9th cause of death for cancer in men and the 10th in women. Unlike other highly-prevalent tumors, scientific evidence for most therapeutic options is limited mainly to small cohorts and retrospective studies. The aim of this study is to characterize and describe epidemiologically patients with diagnosis of hepatocellular carcinoma in the Italian Hospital of Buenos Aires during a 12-year period. Overall survival for our cohort was 58%, 46%, and 36% at 1, 3 and 5 years respectively. Average survival for patients receiving palliative treatment was 5 months, while for those who received either non-curative or curative treatment was 23 and 75 months respectively. Recurrence-free survival for those patients who underwent a curative treatment was 89%, 76% y 61% at 1, 3 and 5 years. A thorough analysis of etiology, risk factors, incidence, mortality and treatment was made. The study's importance lies in its large sample size, quantity and quality of data, and will most certainly stimulate the development of local studies in hepatocellular carcinoma.

Consultorio de Salud Ambiental en un Hospital Privado de Comunidad de la Ciudad de Buenos Aires / Environmental Health consulting office in a Private Community Hospital of the Buenos Aires City

En los últimos años surge el concepto de Una Sola Salud que reconoce la interdependencia sistémica al observar que los cambios en la salud humana se expresan de manera sincrónica e indivisible de la salud del ambiente. Nuevas enfermedades y daños crónicos inespecíficos ocurren a la par de la pérdida de biodiversidad y vitalidad. En las últimas décadas venimos observando el surgimiento de "adaptaciones sistémicas" que requieren un abordaje desde la clínica y la toxicología a nivel individual y desde la epidemiología de la complejidad a nivel poblacional. Luego de un largo recorrido de investigaciones, el Hospital Italiano formalizó el consultorio de Salud Ambiental con la intención de brindar respuesta a la demanda de pacientes que atribuyen síntomas y signos a la polución ambiental. (AU)

In recent years, the concept of One Health has emerged, recognizing the systemic interdependence and the changes in human health that are expressed synchronously and indivisible from the environment. New diseases and nonspecific chronic damage are occuring in parallel with the loss of biodiversity and vitality.In recent decades we have observed the appearance of "systemic adaptations" that require a clinical and toxicological approach at the individual level, and address the population level from an epidemiological and complexity science paradigm. After many years of research, the Hospital Italiano de Buenos Aires formalized the Environmental Health consulting office and the measurement of glyphosate levels, giving answer to the demand of patients who associate their signs and symptoms to environmental pollution.

Do changes in inflammatory markers predict hepatocellular carcinoma recurrence and survival after liver transplantation?

BACKGROUNDS/AIMS: The role of inflammation in malignant cell proliferation has been well described. High values of platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) as markers of systemic inflammation have shown associations with unfavorable long-term outcomes. The purpose of this study was to determine values of NLR and PLR evaluated prior to and after surgery and their associations with mortality and recurrence rates of liver transplant patients with hepatocellular carcinoma (HCC). METHODS: A total of 105 patients with HCC who underwent orthotopic liver transplantation (OLT) were retrospectively reviewed. NLR and PLR values were obtained from complete blood counts prior to and after surgery. Overall survival (OS) and recurrence-free survival (RFS) in relation with delta NLR and PLR were estimated. RESULTS: Serum alpha-fetoprotein levels > 100 ng/mL (p = 0.014) and lymphovascular emboli in the specimen (p = 0.048) were identified to be significant predictors of RFS. Child-Pugh score (p = 0.016) was found to be an independent factor associated with poorer OS. An increasing delta PLR was associated with worse RFS, although it showed no significant association with OS. CONCLUSIONS: The analysis of PLR as a continuous variable may predict recurrence outcomes in patients undergoing OLT for HCC. It is more representative than isolated values.

[Reasons for consultation and healthcare strategies analyzed from a neighborhood dermatological assistance device. Qualitative research: Skin problems. Qualitative research. / Motivos de consulta y estrategias de atención analizados a partir de un dispositivo barrial de asistencia dermatológica. Investigación cualitativa: Afecciones de la piel. Investigación cualitativa.

Aim of study: identify consultation reasons, experiences with seeking dermatological assistance and skin care strategies within neighbours from an urban deprived settlement in Buenos Aires province, Argentina. This setting lies onto a sanitary landfill with a high index of environmental contamination. Materials and methods: a dermatological health care team from the main local hospital designed a dermatological assistance device (DAD), in cooperation with social leaders and institutions of the neighborhood. The DADs included walks around the neighborhood for attending those who could not get a consultation. The experiences were evaluated through a qualitative research strategy, developed from the theoretical framework of Sociocultural Epidemiology. Those who attended the DADs were interviewed. Ethnographic field notes were also recorded. Multiple accessibility barriers to the public health care system were identified and self care practices were also recognized. Results: The most frequent consultations to the DADs were for "pimples", "stains'' and "lumps" on exposed areas of the skin. These lesions generated discomfort or pain, or even affected the interviewees aesthetically or emotionally. Most of them were associated to extremely dry skin and a high sun exposure, in connection with the lack of shade in the neighbourhood. An initiative to plant trees was promoted in order to prevent sun radiation-induced dermatoses. Conclusion: the reflective immersion of the dermatology team in the realm of the neighborhood daily life enabled the development of attention strategies grounded on the perceived needs of the population.

Objetivo: analizar motivos de consulta, experiencias y formas de atención de las afecciones dermatológicas de la población de un asentamiento de la Provincia de Buenos Aires, ubicado sobre un relleno sanitario con altos índices de contaminación ambiental. Materiales y métodos: investigación cualitativa, mediante entrevistas en profundidad a vecinos/as y elaboración de registros etnográficos de las recorridas. La investigación se realizó en el contexto de un dispositivo de atención dermatológica, planificado en conjunto con referentes barriales, bajo el marco teórico de la Epidemiología Sociocultural. Resultados: se identificaron múltiples barreras de accesibilidad a la atención dermatológica en el sistema público de salud, y prácticas de autoatención como el uso de cremas, medidas de higiene y uso de elementos de protección personal para trabajos que significaban un riesgo para la salud. Las consultas al dispositivo más frecuentes fueron "granos", "manchas", "bultitos" en zonas visibles del cuerpo, que generaban molestia, dolor y/o afectaban estética y emocionalmente a lo/as entrevistado/as. Estas consultas se relacionaban principalmente con piel extremadamente seca y patologías por alta exposición solar, coincidiendo con la escasez de sombra en el barrio. Para prevenir patologías relacionadas a la exposición solar, se impulsó una iniciativa para plantar árboles. Conclusión: a partir de la inmersión reflexiva del equipo de atención, en las experiencias de atención de lo/as habitantes del barrio, se desplegaron estrategias según las necesidades percibidas por la población.

[Prostate specific antigen utilization trends in an academic hospital in Argentina.] / Tendencia temporal de realización de Antígeno Prostático Específico en un Hospital Académico de Buenos Aires.

Background: Although prostate cancer (PC) screening with prostate-specific antigen (PSA) determination could decrease mortality, concerns about the potential risk of overdiagnosis led to recommendations against this preventive practice. The objective of this study was to describe the trend in PSA determinations in men between 40 and 79 years old, affiliated to a Health Maintenance Organization (HMO) of an academic hospital in the city of Buenos Aires, Argentina, and its association with the recommendations stated by the U.S. Preventive Task Force (USPSTF) and the Instituto Nacional del Cáncer in Argentina. Methods: We analyzed a time series of aggregated data. We calculated the annual age-standardized rates of accumulated determinations of PSA for every 100 affiliates without a personal history of PC. Additionally, we compared trends by age groups every 10 years. We used Joinpoint and MS Excel programs. Results: Between 2006 and 2011 there was a growing trend in the number of PSA determinations, with an annual average of + 1.2% (95% CI, -1.0 to +3.5). Between 2011 and 2015, the number of determinations began to decrease, with a percentage annual average of -4.1% (-6.9 to -1.1). Conclusion: We found a gradual decrease in PSA utilization in men between 40 and 79 years old after the 2012 USPSTF recommendation against prostate cancer screening.

Introducción: Aunque el rastreo del cáncer de próstata (CP) mediante el dosaje sérico de antígeno prostático específico (en inglés, PSA) podría disminuir la mortalidad, la preocupación por su potencial riesgo de sobrediagnóstico llevó a desaconsejar su realización. El objetivo de este estudio fue describir la tendencia temporal de realización de esta práctica en varones entre 40 y 79 años afiliados a un seguro privado de salud de la ciudad de Buenos Aires, en relación con las recomendaciones de la Fuerza de Tareas Preventivas de los EE.UU. (USPSTF) y el Instituto Nacional del Cáncer de Argentina. Métodos. Serie temporal de datos agregados. Se calcularon las tasas anuales estandarizadas de incidencia acumulada de realización de PSA cada 100.000 afiliados sin antecedentes personales de CP, en el período 2006 a 2015. Adicionalmente, se construyeron curvas de tendencia por grupos etarios cada 10 años. Se utilizaron los programas Joinpoint y MS Excel. Resultados. Entre 2006 y 2011 hubo una tendencia creciente en la realización de PSA, con un promedio anual porcentual de +1,2% (IC 95%, -1,0 a +3,5). Entre 2011 y 2015, el número de determinaciones comenzó a decrecer, con un promedio anual porcentual de -4,1% (-6,9 a -1,1). Conclusión. En un hospital académico de Buenos Aires se observó un descenso paulatino en la realización de PSA en varones entre 40 y 79 años luego de la recomendación de 2012 en contra del rastreo del CP en todos los grupos etarios.

[Prevalence of pain among patients admitted to a clinical hospital]. / Prevalencia de dolor en la internación en un hospital de alta complejidad de Argentina.

BACKGROUND: Pain prevalence during hospital admission is variable, with estimates ranging from 32 to 77%. AIM: To determine pain prevalence during admission to a clinical hospital. MATERIAL AND METHODS: Patients admitted to medical and surgical wards were interrogated about the presence of pain within 48 to 72 hours after admission. Subjective pain was analyzed using a scale ranging from 0 to 10. Data was analyzed separately for medical, surgical, and obstetrical patients. RESULTS: A total of 736 patients aged 18 to 94 years (416 women) were recruited. Pain prevalence at 48 hours after admission was 56% (95% confidence intervals (CI (52.7 to 60.1). Pain prevalence in medical, surgical and obstetric patients was 37% (95% CI 31.4 to 42.1), 70% (95% CI 64.5 to 75.5) and 77% (95% CI 68.6 to 84), respectively. The median pain intensities in medical, surgical, and obstetrical patients were 7 (interquartile range (IQR) 6-8), 7 (IQR 5-8) y 7 (IQR 5-8), respectively. CONCLUSIONS: The prevalence of pain among patients admitted to the hospital is high, especially in obstetric and surgical units.

Analysis of the decrease in deaths due to coronary disease between 1995 and 2010. IMPACT CHD Argentina Study. / [Análisis del descenso de muertes por enfermedad coronaria entre 1995 y 2010. Estudio IMPACT CHD Argentina.]

Objetive: To quantify the contribution of risk factors and treatments in the reduction of mortality due to coronary heart disease in Argentina between 1995 and 2010. Results: We used the validated IMPACTCHD model integrating data on effectiveness, use of treatments and changes in the risk factors between 1995 and 2010 in people older than 25 years in Argentina. The difference between the coronary deaths observed and expected in 2010 was distributed between treatments and risk factors. Conclusions: One out of every two MPP due to coronary heart disease in Argentina between 1995 and 2010 was due to treatments and one third to the improvement of risk factors. The decrease in blood pressure, cholesterol and smoking was limited by increases in the prevalence of obesity, sedentary lifestyle and diabetes. This study was possible thanks to the collaborative work to the cardiovascular epidemiology.

Objetivos: Cuantificar la contribución de los factores de riesgo (FR) y de los tratamientos en el descenso de mortalidad por enfermedad coronaria en Argentina entre 1995 y 2010. Métodos: Utilizamos el modelo validado IMPACTCHD integrando datos de efectividad y utilización de tratamientos y cambios en los FR en 1995 y 2010 en mayores de 25 años en Argentina. La diferencia entre las muertes coronarias observadas y esperadas en el 2010 se distribuyó entre los tratamientos y los FR. Resultados: Entre 1995 y 2010 las tasas ajustadas de mortalidad por enfermedad coronaria descendieron 29,8% (8 500 muertes prevenidas o pospuestas - MPP). Las mejoras en los tratamientos explicaron un 49,9%, en su mayoría por prevención secundaria del infarto agudo de miocardio (8,2%); tratamiento antihipertensivo (11,9%) y para insuficiencia cardíaca (13,2%). Las mejoras en los FR explicaron 32,9% de las MPP: presión arterial sistólica 34,6%; colesterol total 12,8%; tabaquismo 6,8%. Se encontró un exceso de muertes debido al aumento de diabetes (9,4%), obesidad (6,9%) y sedentarismo (5%). Un 17,2% de las MPP no fue explicado por el modelo. Conclusiones: Una de cada dos MPP por enfermedad coronaria en Argentina entre 1995 y 2010 se debió a los tratamientos y un tercio a la mejora de los FR. El descenso de la presión arterial, colesterol y tabaquismo fue limitado por aumentos en la prevalencia de obesidad, sedentarismo y diabetes. Este trabajo fue posible gracias al trabajo colaborativo en pos de la epidemiología cardiovascular.

Construcción de espacios grupales terapéuticos en el ámbito de la internación: relato de experiencia en una unidad de mediana estancia de la ciudad autónoma de Buenos Aires / Construction of therapeutic group spaces in the field of hospitalization: experience report in a medium-stay unit of the city autonomous of Buenos Aires

Este relato de experiencia describe el desarrollo de un dispositivo grupal de socialización en el abordaje de pacientes complejos en rehabilitación a partir del año 2016 en una Unidad de Mediana Estancia (UME) del Hospital Italiano de Buenos Aires. Se partió de reconocer la posibilidad de trabajar en el marco de la psicología social de Pichon-Rivière adaptando la técnica del grupo operativo para ámbitos hospitalarios que generan alto nivel de estrés, desfuncionalización y disrupción de la vida cotidiana. En este relato describimos la conformación, en esta UME, de grupos operativos terapéuticos de pacientes con deterioro físico, cognitivo o en cuidados paliativos. La metodología para el análisis de esta experiencia se basó en el registro prospectivo narrativo de cada encuentro grupal. Presentamos una reflexión teórica sobre las adaptaciones al encuadre y a la planificación de cada actividad grupal, para lograr continuidad y pertenencia grupal, en los grupos operativos desarrollados en este tipo de contexto hospitalario. (AU)

This experience report describes the development of a socialization group device in the approach of complex patients in rehabilitation from 2016 on a Medium-Stay Unit (MSU) of the Hospital Italiano de Buenos Aires. It started by recognizing the possibility of working within the social psychology framework of Pichon-Rivière by adapting the technique of the operative group for hospital environments with high level of stress, defunctionalization and disruption of daily life. In this report we describe the conformation in this MSU of therapeutic operative groups of patients with physical, cognitive or palliative care impairment. The methodology for the analysis was based on the prospective narrative record of each group meeting. We present a theoretical reflection on the adaptations to the framing and the planning of each group activity. This allowed us to achieve continuity and group belonging in the operative groups developed in this hospital context. (AU)

Incidence of hospital-acquired venous thromboembolic disease.

BACKGROUND: There is limited knowledge of the incidence of venous thromboembolic disease (VTE) during hospitalization, since most of these are community-based data. PURPOSE: To estimate the incidence rate (IR) of VTE developed during hospitalization. METHODS: Prospective cohort of all inpatients admitted in a university tertiary hospital, in Argentina. The inclusion criteria were defined as: adult patients consecutively admitted from July/2006 to August/2013, for any cause. Patients admitted for VTE were excluded; all patients at the time of admission were free of event. Each person was followed contributing time at risk, from admission to event, discharge or death. VTE incident cases were captured from the Institutional Registry of Thromboembolic Disease (ClinicalTrials.gov Identifier NCT01372514). Incidence rate was calculated with 95% confidence intervals. RESULTS: The crude incidence rate of VTE for clinical patients was 0.49 (95%CI 0.45-0.55) per 1,000 cases person-days, and IR adjusted for WHO was 0.23 (95%CI 0.19-0.26). The crude IR of VTE for surgical patients was 0.25 (95%CI 0.23-0.27), and IR adjusted for WHO was 0.13 (95%CI 0.10-0.17). The incidence rate ratio (IRR) for VTE shows that surgical admission reduces the IRR and age categories increases the thrombosis rate risk, after adjustment for age category, sex and surgical admission. CONCLUSIONS: This study suggests that there is a high risk of VTE in hospitalized patients and is still a frequent problem.

Role of the Mechanisms of Detection in the Increased Risk of Thyroid Cancer: A Retrospective Cohort Study in an HMO in Buenos Aires.

BACKGROUND: Two hypotheses attempt to explain the increase of thyroid cancer (TC) incidence: overdetection by excessive diagnostic scrutiny and a true increase in new cases brought about by environmental factors. Changes in the mechanism of detection and the risk of incidentally diagnosed TC could result in an increase of TC incidence. METHODS: Retrospective cohort study. We identified incident cases of TC from the pathological reports of patients in a HMO and review of clinical records. The results were analyzed in two periods: 2003-2007 and 2008-2012. Incidence rates expressed per 100,000 person-years (with 95% CI) and relative risk of incidence rates of incidental and nonincidental TC were estimated. RESULTS: The relative risk of incidentally detecting a thyroid cancer in 2008-2012 compared to 2003-2007 was 6.06 (95%CI 1.84-20.04). Clinical evaluations detected 31 (75.6%) cancers in the period 2003-2007 and 70 (51.8%) cancers in the period 2008-2012 (p<0.007). Although tumor median size was significantly lower in the period 2008-2012 (10 vs. 14 mm, p<0.03), tumors greater than 40 mm (4.3%) were only present in 2008-2012. The female/male ratio decreased between analyzed periods from 8 (3-21) to 4 (3-7). CONCLUSIONS: Our findings partially support the hypothesis of increased incidence due to overdetection but do not explain the changes in the increase of larger tumors and decrease in the female/male ratio, which could be secondary to the influence of unidentified environmental factors.

Incidence rate of symptomatic venous thromboembolic disease in patients from a medical care program in Buenos Aires, Argentina: a prospective cohort.

BACKGROUND: The incidence of venous thromboembolic disease (VTED) is estimated to be, on average, 1-2 cases per 1,000 individuals per year worldwide. There are few data concerning the incidence rate (IR) of VTED in the Argentinean population at large.Our aim was to estimate the IR of VTED at the Italian Hospital Medical Care Program (IHMCP) in Buenos Aires, the most populous city in Argentina. METHODS: This prospective cohort study evaluated all consecutive incident cases of pulmonary thromboembolism (PTE) and deep vein thrombosis (DVT) confirmed in patients over the age of 17 who were members of the IHMCP from June 2006 to May 2012. Any patient who had an initial confirmed VTED episode and was a member of the IHMCP at the time of diagnosis was considered an incident case. RESULTS: There were 1,138 cases of VTED for 687,871 person-years of follow-up. The crude IR of VTED was 1.65 (95% CI: 1.56 to 1.75) per 1,000 person-years. The highest IR was found in subjects >80 years old (5.92 per 1,000 person years; 95% CI: 5.41 to 6.49).The IRs adjusted to the population of the city of Buenos Aires were 0.90 (95% CI: 0.84 to 0.95) for VTED, 0.71 (95% CI: 0.66 to 0.76) for DVT, and 0.34 (95% CI: 0.31 to 0.37) for PTE. CONCLUSIONS: VTED is a common health problem with a high IR in members of the IHMCP, especially the elderly. This is the first paper to report prospectively the cumulative incidence of VTED in Latin America.

Incidence and prevalence of amyotrophic lateral sclerosis in an HMO of Buenos Aires, Argentina.

The incidence of amyotrophic lateral sclerosis (ALS) ranges from 1.7 to 2.3 per 100,000 persons worldwide. Few epidemiological studies have been published in Latin America. The aim of this study was to estimate the incidence and prevalence of ALS in an HMO (Health Maintenance Organization) of Buenos Aires, capital city of Argentina. The population studied was affiliates of the Italian Hospital Medical Care Program, whose distribution across age and gender strata is similar to the population of Buenos Aires. Cases were detected from 1 January 2003 to 31 December 2010. Incidence density (ID) and prevalence for ALS were estimated for the whole period and at 31 December 2010, respectively. During the seven-year study period, the crude ID estimated was 3.17 per 100,000 person-years (95% CI 2.24-4.48) and the age-adjusted ID for the Buenos Aires population was 2.23 per 100,000 person-years (95% CI 1.45-3.01). Point prevalence at 31 December 2010 was 8.86 per 100,000 persons (95% CI 4.05-13.68). Mean age at diagnosis was 72.29 years (SD 8.5). In conclusion, estimated age-adjusted ID and prevalence of ALS were similar to the incidence and prevalence rates found in other geographical areas.

Diffuse hyperplastic perilobar nephroblastomatosis.

Nephroblastomatosis is a rare preneoplastic lesion defined as the presence of diffuse or multifocal nephrogenic rests. They are divided into 4 categories: perilobar, intralobar, combined, and universal. The aim of this report is to describe a case of diffuse hyperplastic perilobar nephroblastomatosis. A 1-year-old boy presented with an abdominal mass on the left side. Computed tomography scan showed a homogeneous, isointense enlarged left kidney. A fine needle aspiration cytology was reported as Wilms tumor. After chemotherapy, the left kidney was excised. Nephrectomy specimen presented a thick cortical rim of hyperplastic nephrogenic tissue, well delineated from preserved renal parenchyma without pseudocapsule. Nephroblastomatosis is a rare condition affecting renal parenchyma. Diagnosis is based on imaging studies, such as ultrasound, computed tomography scan, and magnetic resonance imaging. Fine needle aspiration cytology is of limited value. Therapeutic management is controversial. Chemotherapy is used preoperatively, and surgical excision may be an alternative for refractory cases.
