ABSTRACT
BACKGROUND: Treating cancer-associated venous thromboembolism (CAT) with anticoagulation prevents recurrent venous thromboembolism (rVTE), but increases bleeding risk. OBJECTIVES: To compare incidence of rVTE, major bleeding, and all-cause mortality for rivaroxaban versus low molecular weight heparin (LMWH) in patients with CAT. METHODS: We developed a cohort study using Swedish national registers 2013-2019. Patients with CAT (venous thromboembolism within 6 months of cancer diagnosis) were included. Those with other indications or with high bleeding risk cancers were excluded (according to guidelines). Follow-up was from index-CAT until outcome, death, emigration, or end of study. Incidence rates (IR) per 1000 person-years with 95% confidence interval (CI) and propensity score overlap-weighted hazard ratios (HRs) for rivaroxaban versus LMWH were estimated. RESULTS: We included 283 patients on rivaroxaban and 5181 on LMWH. The IR for rVTE was 68.7 (95% CI 40.0-109.9) for rivaroxaban, compared with 91.6 (95% CI 81.9-102.0) for LMWH, with adjusted HR 0.77 (95% CI 0.43-1.35). The IR for major bleeding was 23.5 (95% CI 8.6-51.1) for rivaroxaban versus 49.2 (95% CI 42.3-56.9) for LMWH, with adjusted HR 0.62 (95% CI 0.26-1.49). The IR for all-cause mortality was 146.8 (95% CI 103.9-201.5) for rivaroxaban and 565.6 (95% CI 541.8-590.2) for LMWH with adjusted HR 0.48 (95% CI 0.34-0.67). CONCLUSIONS: Rivaroxaban performed similarly to LMWH for patients with CAT for rVTE and major bleeding. An all-cause mortality benefit was observed for rivaroxaban which potentially may be attributed to residual confounding. TRIAL REGISTRATION NUMBER: NCT05150938 (Registered 9 December 2021).

BACKGROUND: Liver disorders are important adverse effects associated with antifungal drug treatment. However, the accuracy of Clinical International Classification of Diseases (ICD)-10 codes in identifying liver disorders for register based research is not well-established. This study aimed to determine the positive predictive value (PPV) of the ICD-10 codes for identifying patients with toxic liver disease, hepatic failure, and jaundice among patients with systemic antifungal treatment. METHODS: Data from the Swedish Prescribed Drug Register and the National Patient Register were utilized to identify adult patients who received systemic azole antifungal drugs and had a recorded diagnosis of toxic liver disease (K71.0, K71.1, K71.2, K71.6, K71.8, K71.9), hepatic failure (K72.0, K72.9), or jaundice (R17) between 2005 and 2016. The medical records of all included patients were reviewed. Prespecified criteria were used to re-evaluate and confirm each diagnosis, serving as the gold standard to calculate PPVs with 95% confidence intervals (95% CI) for each diagnostic group. RESULTS: Among the 115 included patients, 26 were diagnosed with toxic liver disease, 58 with hepatic failure, and 31 with jaundice. Toxic liver disease was confirmed in 14 out of 26 patients, yielding a PPV of 53.8% (95% CI 33.4-73.4%). Hepatic failure was confirmed in 26 out of 38 patients, resulting in a PPV of 62.1% (95% CI 48.4-74.5%). The highest PPV was found in jaundice, with 30 confirmed diagnoses out of 31, yielding a PPV of 96.8% (95% CI 83.3-99.9%). CONCLUSION: Among patients who received azole antifungal treatment and were subsequently diagnosed with a liver disorder, the PPV for the diagnosis of jaundice was high, while the PPVs for toxic liver disease and hepatic failure were lower.

Special Article Introduction Hematopoietic stem cell transplantation is the only curative treatment for many disorders and international data shows a growing trend. Method We aimed to evaluate the temporal trends in HSCT transplant rates in Argentina. A time-series analysis was performed for the period 2009 to 2018 using the national database from the National Central Coordinating Institute for Ablations and Implants. Crude and standardized transplant rates were calculated. A permutation joinpoint regression model analysis was used to identify significant changes over time. Results Altogether, 8,474 transplants were reported to INCUCAI by 28 centers (autologous 67.5%); the main indication was multiple myeloma (30%). The WHO age-sex standardized HSCT rates for the entire country were 153.3 HSCT/10 million inhabitants (95% CI 141.7-165.8) in 2009 and 260.1 HSCT/10 million inhabitants (95% CI 245.5-275.5) in 2018. There was a large gap in HSCT rates among the states and regions. The transplant rate was higher for autologous transplants throughout the years. Within the allogeneic group, the related donor transplant rate was higher than the unrelated donor transplant rate. The joinpoint regression analysis of HSCT rates for the whole country over time showed an observed annual percentage change of 6.3% (95% CI 5.4-7.3; p< 0.01). No changes were observed for unrelated donors during the study period. Conclusions Age-sex standardized HSCT rates in Argentina are increasing, mainly due to autologous and family donor allogeneic transplants. A wide variation across the country was found, demonstrating differences in the access to transplantation among Argentine regions.

Background: Undertriage or the underestimation of the urgency of the condition of a person arriving in an emergency department (ED) represents a measure of quality care. Aim: To estimate the prevalence of undertriage in a high complexity hospital of Argentina; to describe characteristics and mortality of these patients. Material and Methods: All consultations admitted to the ED during 2014 were analyzed. Those assigned to a lower level of admission risk (classified as Emergency Severity Index -ESI- 3 to 5) but required hospitalization in intensive care units (ICU) as the first hospitalization place were considered as an undertriage. A random sample of correctly categorized admissions (ESI 1 or 2), who were subsequently hospitalized in the ICU, was selected as a comparison group. Results: The global undertriage prevalence was 0.30% (316/104,832). Among patients admitted to the ICU, the prevalence was 21% (316/1,461; 95% confidence intervals (CI) 19-24). The 316 patients whose severity was underestimated had a median age of 73 years, and admitted between 7 a.m. and 9 p.m. in a greater proportion. Overall hospital mortality was 8.9% (95% CI 6.78-11.38), and all deaths occurred after the patient was transferred from the emergency room. There were no differences in mortality between patients with correct triage or undertriage (11 and 7% respectively, p = 0.09). No differences were observed either in the total number of critical interventions during care in the first 24 hours. Significant differences were observed in requirements for mechanical ventilation (11 and 4% respectively, p = 0.01), orotracheal intubation (10 and 5% respectively p = 0.01) and non-invasive ventilation (8 and 4% respectively, p = 0.05). Conclusions: Undertriage rate in this series was low, but it can be improved.

INTRODUCCIÓN El impacto indirecto que la pandemia COVID-19 y el Aislamiento Social Preventivo y Obligatorio ha tenido en el escenario del trasplante hepático ha sido escasamente reportado en Argentina. OBJETIVOS Evaluar el efecto de la pandemia de COVID-19 y del Aislamiento Social Preventivo y Obligatorio en los siguientes indicadores; ingreso a la lista de espera de trasplante hepático, muerte en lista de espera, y número de trasplantes hepáticos. MÉTODOS Estudio ecológico de series temporales que evaluó el efecto de la pandemia comparando los indicadores mencionados en el año 2019 (período no expuesto) y el año 2020 (período expuesto). Las tasas se construyeron con datos del INCUCAI y del INDEC. Se aplicaron modelos de regresión segmentada de Poisson. RESULTADOS Entre el año 2019 y el 2020 se observó una reducción del 36,7% en la tasa de ingreso en lista de espera, una reducción del 47,9% en la tasa de trasplante hepático y una reducción del 36% en mortalidad en lista de espera. Al evaluar el ingreso en lista de espera, la razón de incidencias de la cuarentena ajustada por la pandemia, la incidencia de COVID-19 en el país y el tiempo fue de 0,68 (IC95% 0,50 - 0,93, p 0,017). La razón de incidencias de la circulación comunitaria fue de 0,42 (IC95% 0,27 - 0,66, p<0,001) ajustada por la pandemia, cuarentena, la incidencia de COVID-19 en el país y el tiempo. Al evaluar la mortalidad en lista de espera, la razón de incidencias de la cuarentena ajustada por la pandemia, la incidencia de COVID19 en el país y el tiempo fue de 0,87 (IC95% 0,49 - 1,55, p 0,636). La razón de incidencias de la circulación comunitaria fue de 0,74 (IC95% 0,26 - 2,12, p 0,575) ajustada por la pandemia, cuarentena, la incidencia de COVID-19 en el país y el tiempo. Al evaluar el número de trasplantes hepáticos, la razón de incidencias de la cuarentena ajustada por la pandemia, la incidencia de COVID-19 en el país y el tiempo fue de 0,77 (IC95% 0,54 - 1,08, p 0,128). La razón de incidencias de la circulación comunitaria fue de 0,48 (IC95% 0,28- 0,82, p 0,008) ajustado por la pandemia, cuarentena, la incidencia de COVID19 en el país y el tiempo. DISCUSIÓN Los indicadores de trasplante hepático se redujeron significativamente entre el año 2019 y 2020. Es probable que esto esté ligado con las medidas que se aplicaron para el control de la pandemia, además de los efectos directos de la misma. Si bien no se observó un efecto directo en la mortalidad en lista de espera, esto podría estar explicado por casos de muerte que hayan ocurrido antes del ingreso a lista de espera producto de las dificultades para acceder a la misma

Qualitative ResearchABSTRACT
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.

Background: Crowding in Emergency Departments (ED), results from the imbalance between the simultaneous demand for health care and the ability of the system to respond. The NEDOCS scale (National Emergency Department Crowding Scale) measures the degree of crowding in an ED. Aim: To describe ED Crowding characteristics, using the NEDOCS scale, in an Argentinean hospital. Material and Methods: A retrospective cohort study was conducted with all adult patient consultations between July 2013 and July 2014 at the ED of Hospital Italiano de Buenos Aires. We included all hours in the analysis period (365 days x 24 h = 8,760). The NEDOCS value was calculated for each hour using an automatic algorithm and was quantified in a six points score. Levels 4 (overcrowded), 5 (severely overcrowded) and 6 (dangerously overcrowded) were defined as overcrowding. Contour plots analysis was applied to identify patterns. Results: During the study period, 124,758 visits to the ED were registered. Overcrowding was present in 57.7% (5,055) of the analyzed hours. A predominance of scores between four and five was observed between 10:00 and 24:00 hours. The months with predominance of overcrowding were June, July and August (southern winter). Conclusions: The calculation of the NEDOCS score and the analysis of its temporal distribution are highly relevant to identify opportunities for improvement and to develop mechanisms to prevent the highest categories of overcrowding.

ABSTRACT Objectives The main purpose of this study was to estimate the incidence rate and prevalence of clinically relevant pituitary adenomas (PAs) within the Hospital Italiano Medical Care Program (HIMCP), a well-defined population of 150,000 members living in the urban and suburban area of the city of Buenos Aires. We defined clinically relevant PAs as those associated with endocrine dysfunction and/or mass effect. Subjects and methods A retrospective open cohort study was conducted, including all members of the HIMCP over 18 years old, with active memberships during the period of the study, from January 1st 2003, to January 1, 2014. The incidence rates (IRs) were standardized (SIR) to the World Health Organization (WHO) 2000 standard population and were expressed per 100,000 members/year. Prevalence was estimated at January 1, 2014, and was expressed per 100,000 persons. The clinical records have been electronically managed since 2001. All lab and imaging studies were done in-house. Results The overall SIR was 7.39/100,000/year (95% CI 4.47-10.31). Female patients had a specific IR significantly higher than male patients (5.85 vs.1.54) and represented 73% of the affected members. Regarding tumor size, 61.4% were microadenomas, and the mean age at diagnosis was 46.4 years. Prolactinomas had the highest SIR (5.41), followed by acromegaly (Acro) and non-functioning adenomas (NFAs) with overlapping 95% CIs (0.44-1.41 and 0.31-0.99, respectively). Microprolactinomas were more frequent in female (72.6%) (p < 0.01) and younger members (38 vs.60 years; p < 0.04). The overall prevalence rate was 97.76/100,000. Prolactinomas had the highest prevalence (56.29), followed by NFAs (21.48), Acro (14.07) and CD (5.93). Conclusion Our results demonstrate that clinically relevant PAs are more common than usually suspected, especially prolactinomas and growth-hormone secreting PAs. These data highlight the need to increase the awareness of PAs, thereby enabling early diagnosis and treatment.

La edad está asociada con un aumento de la prevalencia de múltiples enfermedades y también con un deterioro de la reserva funcional y fisiológica. Los pacientes adultos mayores tienen un riesgo aumentado para el desarrollo de complicaciones frente a cirugías y diversas prácticas oncológicas. Los procesos de toma de decisiones en muchos casos son complejos, y la detección de toda esta comorbilidad geriátrica no está contemplada en muchos de los modelos clásicos para predicción de riesgo. En este artículo se describe una herramienta de evaluación geriátrica integral dirigida a la detección de riesgos para prácticas y procedimientos (DRIPP) en el adulto mayor, que fue desarrollada y se utiliza en el ámbito del Hospital Italiano de Buenos Aires. El objetivo de DRIPP es la detección de factores de riesgo clínicos y geriátricos asociados con malos resultados, a partir del cual se generan recomendaciones específicas de manejo, que aportan mayor información para el buen desarrollo del proceso de consentimiento informado y la toma de decisiones. Su integración transversal y longitudinal con las diferentes disciplinas e instancias para el seguimiento del paciente es una característica esencial que se traduce en ventajas asistenciales y académicas.

Aging is associated with an increased prevalence of multiple diseases, and also with decline in functional and physiologic reserve. Elderly patients have an increased risk to develop complications after surgeries and various oncological interventions. Decision-making processes are complex in several cases, and detection of all this geriatric comorbidity is not covered by many of the classic models for risk prediction. This article describes a comprehensive geriatric assessment tool for detection of risks for practices and procedures (DRIPP) in the elderly, which was developed and is used in the setting of Hospital Italiano de Buenos Aires. The aim of DRIPP is the systematic detection of clinical and geriatric risk factors associated with poor outcomes, and from which specific management recommendations are generated, as well as provides more information for the proper development of the informed consent and decision making processes. The transverse and longitudinal integration with different disciplines and instances for patient's follow up, are an essential feature, resulting in healthcare and academic advantages. (AU)
