Short bowel syndrome related intestinal failure outcomes in Latin America: Insights from the RESTORE Registry.

BACKGROUND: Short bowel syndrome is considered a low prevalence disease. The scant information available about intestinal failure in Latin America was the driving force to expand this registry. METHODS: A prospective, multicenter observational registry was created for patients with chronic intestinal failure short bowel at specialized centers in Latin America. Demographics, clinical characteristics, nutrition assessment, parenteral nutrition management, intestinal rehabilitation, related complications, clinical outcome, and survival were analyzed. RESULTS: From May 2020 to July 2023, 167 patients (115 adults, 52 children) from 20 centers were enrolled. For the adults, the mean age was 37.2 ± 18 years, 48% were female, and the mean follow-up was 22.6 ± 18.3 months. The main etiology was surgical resections (postsurgical complications: 37%; ischemia: 25%); the mean intestinal length was 73 ± 55 cm. The complications were as follows: infections: 0.4/1000 catheter-days; thrombosis: 0.24/1000 catheter-days; liver disease: 2.6%. The outcomes were as follows: 28% were rehabilitated, 15% died, 9.6% were lost to follow-up, 0.9% underwent transplant, and 45.6% continued follow-up. For the children, the mean age 48 ± 52 months, 48% were female, 52% were premature. The mean follow-up was 17.2 ± 5.6 months; the mean remaining intestinal length was 38 ± 45 cm. The leading etiologies were atresia (25%), NEC (23%), and gastroschisis (21%). The complication were as follows: infections: 2/1000 catheter-days; thrombosis: 2.22/1000 catheter-day; 25% developed liver disease. The outcomes were as follows: 7.7% died, 3.8% were rehabilitated, and 88.5% continued follow-up. CONCLUSION: The RESTORE amendment served as a registry and educational tool for the participating teams. The aspiration is to objectively show current aspects of intestinal failure in the region and carry them to international standards. Including all Latin American countries and etiologies of chronic intestinal failure besides short gut would serve to complete this registry.

[Argentinean registry on the management of Helicobacter pylori infection: effectiveness and safety of first line treatment]. / Registro argentino para el manejo de la infección por Helicobacter pylori: efectividad y seguridad de los esquemas de primera línea de tratamiento.

INTRODUCTION: The optimal management of Helicobacter pylori (H pylori) infection remains unclear. Updated information concerning local data is needed to design the best strategy to treat H. pylori infection to reach high eradication rates. The Argentinean Registry (Hp-ArgReg) on H. pylori management was launched to monitor the eradication practices of gastroenterologists. The objective was to assess the effectiveness and safety of firstline H. pylori treatment in Argentina. MATERIALS AND METHODS: A multicenter prospective registry of the clinical practice of the Argentinean gastroenterologists concerning H. pylori infection (Hp-ArgReg) was developed. Variables included: patient demographic information, previous eradication attempts, prescribed treatment, adverse events, compliance and outcome. RESULTS: Overall, 800 patients were included and 727 patients received first-line empirical treatment. The most frequent treatment indications were dyspepsia (78%) and gastroduodenal ulcer (12%). Among first-line treatments, quadruple therapies (with or without bismuth) achieved eradication rates of 94.9%, while triple therapies achieved eradication rates of 78.9%. Quadruple therapies were significantly more effective than triple therapies (P < 0.01, OR 5, CI 2.95-8.6). Sequential therapy with zinc showed an effectiveness of 95.6%. Adverse events were reported in 29% of the cases (mainly mild) and tolerance was quite similar among therapies. CONCLUSION: in Argentina, Quadruple therapies with or without bismuth and sequential therapy with zinc showed an H. pylori eradication effectiveness of over 90% in real clinical practice. Local Registries for H pylori management could help to control the spread of antibiotic resistance.

Introducción: El óptimo manejo de la infección por Helicobacter pylori (H. pylori) es objeto de debate. Contar con datos locales ayudaría a lograr altas tasas de erradicación. El Registro Argentino H. pylori (RegArg-Hp) se estableció con el objetivo de monitorear el manejo local de la infección. El objetivo fue describir la efectividad y seguridad de las terapias empíricas de primera línea para la erradicación del H. pylori utilizadas en Argentina. Materiales y métodos: Registro prospectivo, multicéntrico, de la práctica clínica de los gastroenterólogos argentinos. Se incluyeron datos demográficos de pacientes con infección por H. pylori, intentos previos de erradicación, tratamiento indicado, eventos adversos, cumplimiento y erradicación. Resultados: De 800 pacientes incluidos, 727 recibieron un tratamiento empírico de primera línea. Las indicaciones de tratamiento más frecuentes fueron dispepsia (78%) y úlcera gastroduodenal (12%). Entre los tratamientos de primera línea, las terapias cuádruples (con o sin bismuto) lograron tasas de erradicación del 94.9% mientras las terapias triples tasas de erradicación del 78.9%. Las terapias cuádruples fueron significativamente más efectivas que las triples (P < 0.01, OR 5, IC 2.95-8.6). La terapia secuencial con zinc mostró una efectividad del 95.6%. Se reportaron eventos adversos en el 29% de los pacientes, generalmente leves y con una tolerancia similar entre las diferentes terapias. Conclusiones: En Argentina, las terapias cuádruples con o sin bismuto y la secuencial con zinc presentaron una efectividad de erradicación de H. pylori superior al 90%. La implementación de registros locales podría contribuir al control de la resistencia a los antibióticos.

External validation of the parsimonious EuroLung risk models: analysis of the Brazilian Lung Cancer Registry.

OBJECTIVE: The purpose of this study was to assess performance in the Brazilian Lung Cancer Registry Database by using the parsimonious EuroLung risk models for morbidity and mortality. METHODS: The EuroLung1 and EuroLung2 models were tested and evaluated through calibration (calibration plot, Brier score, and the Hosmer-Lemeshow test) and discrimination (ROC AUCs), in a national multicenter registry of 1,031 patients undergoing anatomic lung resection. RESULTS: The evaluation of performance in Brazilian health care facilities utilizing risk-adjustment models, specifically EuroLung1 and EuroLung2, revealed substantial miscalibration, as evidenced by calibration plots and Hosmer-Lemeshow tests in both models. In terms of calibration, EuroLung1 exhibited a calibration plot with overlapping points, characterized by a slope of 1.11 and a Brier score of 0.15; the Hosmer-Lemeshow test yielded a statistically significant p-value of 0.015; and the corresponding ROC AUC was 0.678 (95% CI: 0.636-0.721). The EuroLung2 model displayed better calibration, featuring fewer overlapping points in the calibration plot, with a slope of 1.22, with acceptable discrimination, as indicated by a ROC AUC of 0.756 (95% CI: 0.670-0.842). Both models failed to accurately predict morbidity and mortality outcomes in this specific health care context. CONCLUSIONS: Discrepancies between the EuroLung model predictions and outcomes in Brazil underscore the need for model refinement and for a probe into inefficiencies in the Brazilian health care system.

Socioeconomic factors and COVID-19 mortality in immune-mediated rheumatic diseases patients: regional analysis from Argentina, Mexico and Brazil.

BACKGROUND: SARS-CoV-2 infection has become a major international issue, not only from a medical point of view, but also social, economic and political. Most of the available information comes from the United States, Europe, and China, where the population and the socioeconomic status are very different from Latin American countries. This study evaluates the effect of regional socioeconomic characteristics on mortality due SARS-CoV-2 infection in patients with immune-mediated rheumatic diseases (IMRD) from Argentina, Mexico and Brazil. METHODS: Data from three national registries, SAR-COVID (Argentina), CMR-COVID (Mexico) and ReumaCoV-Brasil (Brazil), were combined. Adult IMRD patients with SARS-CoV-2 infection were recruited. National data for each province/state, including population density, number of physicians per inhabitant, income, unemployment, GINI index, Municipal Human Development Index (MHDI), stringency index, vaccination rate and most frequent viral strains per period were assessed as risk factors for mortality due to COVID-19. RESULTS: A total of 4744 patients were included, 2534 (53.4%) from SAR-COVID, 1166 (24.6%) from CMRCOVID and 1044 (22.0%) from ReumaCoV-Brasil. Mortality due to COVID-19 was 5.4%. In the multivariable analysis, higher number of physicians per 1000 inhabitants and being infected during the vaccination period of each country were associated with lower mortality. After adjustment for socioeconomic factors, there was no association with country of residence and mortality. CONCLUSION: These findings corroborate the complex interplay between socioeconomic factors, rheumatic disease activity, and regional disparities as determinants of death due to COVID-19 in Argentina, Brazil and Mexico. Thus, this research provides valuable insights for guiding public health policies and clinical practice in the ongoing fight against the COVID-19 pandemic.

Clinical and Sociodemographic Features of Alopecia Areata in Five Colombian Cities: An Analysis of the RENAAC Registry. / [Artículo traducido] Características clínicas y sociodemográficas de la alopecia areata en 5 ciudades colombianas: un análisis del RENAAC.

BACKGROUND: Alopecia areata (AA) is an autoimmune disease characterized by non-scaring hair loss and preservation of hair follicles. The information available on disease course, and clinical features of AA is scarce worldwide, and almost nonexistent in Colombia. OBJECTIVE: To determine the clinical and sociodemographic characteristics of patients diagnosed with AA who presented to a dermatology consultation in five Colombian cities. MATERIAL AND METHODS: This was a retrospective and multicenter study on data from an ongoing National Registry of Alopecia Areata in Colombia (RENAAC) collected in Bogota, Cali, Cartagena, Barranquilla, and Medellin, Colombia from March 2022 through April 2023. Data was recorded in a standardized form by trained physicians. The variables were expressed as measures of central tendency and dispersion, and absolute and relative frequencies. RESULTS: A total of 562 patients were included, 59.4% of whom were women, aged between 15 and 49 years (63.9%) with a mean disease course of 1.7 years. The most common finding was multiple plaque (53.2%), the predominant AA subtype was patchy (71.4%), and 29.5% of the patients had a past dermatological history, 18.3% had a past endocrinological history, and 8.9% had a past psychiatric history. The treatments most widely used were steroid injections (76.4%), 5% topical minoxidil (46.4%), followed by high-potency corticosteroids (42.5%). STUDY LIMITATIONS AND CONCLUSIONS: AA was slightly predominant in women. As seen in other populations, this disease had an earlier onset in men vs women. Presentation in pediatric age was uncommon. The previous history of other dermatological diseases was checked in almost one third of the patients. Analysis of the co-presentation of AA with other autoimmune diseases is biased due to excluding patients with systemic erythematous lupus from the study.

[Etiology of epilepsy in Mexico: results from the national multi-centre register]. / Etiología de la epilepsia en México: resultados del registro multicéntrico nacional.

INTRODUCTION: Epilepsy affects millions of people and its geographical patterns are usually linked to etiological aspects. Our objective was to describe main etiologies of epilepsy in Mexico. PATIENTS AND METHODS: We selected patients from the Multicenter Epilepsy Registry carried out from 2021 to 2022 in 89 Mexican hospitals in 31 states, a sample predominantly of pediatric age. Only patients with electroencephalography and neuroimaging studies were included. RESULTS: We analyzed 6,653 patients with documented etiologies. Etiology frequency with confidence interval (95% CI) was: structural 46.1% (44.9-47.3), genetic 12.9% (12.1-13.7), infectious 2.9%. (2.5-3.3), metabolic 1.4% (1.1-1.7), immune 0.9% (0.8-1.3) and unknown 40.9% (39.8-42.2). The two main structural etiologies were malformations of cortical development and hypoxic-ischemic encephalopathy. Neurocysticercosis represented a minority with only 1%. Structural and genetic etiologies were associated with focal and generalized onset seizures respectively. Status epilepticus was identified, mostly with motor component, associated with immune and infectious etiologies. Comorbidities were found in 61.6%, mainly neurological development disorders. Drug-resistant epilepsy was more common in patients with immune, infectious and structural etiologies. CONCLUSIONS: The main etiology of epilepsy was structural. The frequency of genetic etiology was relatively lower than in other series, possibly due to the limited availability of genetic tests. Despite technological advances, a large fraction of epilepsies still has unknown origin.

TITLE: Etiología de la epilepsia en México: resultados del registro multicéntrico nacional.Introducción. La epilepsia afecta a millones de personas y sus patrones geográficos suelen estar vinculados a aspectos etiológicos. Nuestro objetivo fue describir las principales etiologías de epilepsia en México. Pacientes y métodos. Seleccionamos a pacientes del Registro Multicéntrico de Epilepsia realizado de 2021 a 2022 en 89 hospitales mexicanos de 31 estados, una muestra con predominio en edad pediátrica. Se incluyó a pacientes con estudios de electroencefalografía y neuroimagen. Resultados. Analizamos a 6.653 pacientes con etiologías documentadas. Las frecuencias de etiologías con intervalo de confianza al 95% fueron: estructural, 46,1% (44,9-47,3); genética, 12,9% (12,1-13,7); infecciosa, 2,9% (2,5-3,3); metabólica, 1,4% (1,1-1,7); inmunitaria, 0,9% (0,8-1,3); y desconocida, 40,9% (39,8-42,2). Las dos principales etiologías estructurales fueron las malformaciones del desarrollo cortical y la encefalopatía hipóxico-isquémica. La neurocisticercosis representó una minoría, con sólo el 1%. Las etiologías estructurales y genéticas se relacionaron con crisis de inicio focal y generalizado, respectivamente. Se identificó estado epiléptico, en su mayoría con componente motor, asociado a etiologías inmunitarias e infecciosas. Se encontraron comorbilidades en el 61,6%, principalmente trastornos del desarrollo neurológico. La epilepsia farmacorresistente fue más frecuente en pacientes con etiologías inmunitaria, infecciosa y estructural. Conclusiones. La principal etiología de la epilepsia fue estructural. La frecuencia de etiología genética fue menor que en otras series por la limitada disponibilidad de pruebas genéticas. A pesar de los avances tecnológicos, una gran parte de las epilepsias aún tiene un origen desconocido.

Past trends and future projections of palliative care needs in Chile: analysis of routinely available death registry and population data.

BACKGROUND: The number of people with palliative care needs is projected to increase globally. Chile has recently introduced legislation for universal access to palliative care services for patients with severe and terminal illnesses, including non-cancer conditions. We aimed to estimate the number of people affected by serious health-related suffering and need for palliative care in Chile to 2050. METHODS: We used data on all deaths registered in Chile between 1997-2019 and population estimates for 1997-2050. We used Poisson regression to model past trends in causes of death adjusted by age, sex and population estimates, to project the number of deaths for each cause from 2021 to 2050. We applied the Lancet Commission on Palliative Care and Pain Relief weights to these projections to identify decedents and non-decedents with palliative care needs. RESULTS: Population palliative care needs in Chile are projected to increase from 117 (95% CI 114 to 120) thousand people in 2021 to 209 (95% CI 198 to 223) thousand people in 2050, a 79% increase (IRR 1.79; 95% CI 1.78-1.80). This increase will be driven by non-cancer conditions, particularly dementia (IRR 2.9, 95% CI 2.85-2.95) and cardiovascular conditions (IRR 1.86, 95% CI 1.83-1.89). By 2050, 50% of those estimated to need palliative care will be non-decedents (not expected to die within a year). CONCLUSIONS: Chile will experience a large increase in palliative care needs, particularly for people with dementia and other non-cancer conditions. Improved availability of high-quality services, expanded clinician training and new sustainable models of care are urgently required to ensure universal access to palliative care.

Health insurance and clinical outcomes in patients with chronic heart failure in Latin America: an observational study of the Colombian Heart Failure Registry (RECOLFACA).

The effect of the health insurance type on the prognosis of heart failure (HF) patients in Colombia and Latin America is poorly known. We aimed to analyze the characteristics of HF patients that participated in the Colombian Heart Failure Registry (RECOLFACA) as stated by their health insurance type and their relationship with the immediate prognosis of these patients. Patients with HF diagnosis were included in the RECOLFACA registry between 2017-2019. The registry was conducted in 60 centers in Colombia. All-cause mortality was the principal outcome. To evaluate the impact of health insurance on mortality, a Cox proportional hazards regression model was used. The Kaplan-Meier analysis was performed to compare survival probabilities according to insurance type. All statistical analyses were two-tailed and were considered significant with a p value < 0.05. Of the 2,528 participants enrolled in the registry, 99% held details about their health insurance. Of those, 897 patients (35.6%) were covered by public insurance. These patients were significantly younger, with a lower proportion of men, more frequently from rural origin, and lower prevalence of most comorbidities (omitting hypertension, chronic obstructive pulmonary disease (COPD), and Chagas disease) than those with private insurance. Furthermore, patients with public insurance had a worse functional class, as well as a poorer quality of life, and lower frequency of use of implantable devices, while exhibiting similar prescription rates of triple medical therapy for HF. Finally, no differences in short-term mortality were observed between the two groups (HR 1.09; 95% CI 0.79, 1.51). The type of health insurance represents a condition related with relevant differences in the profile of patients with HF in Colombia. Despite this, no significant differences were detected in the short-term prognosis of these patients based on the type of health insurance.

Examining concordance with the guidelines of the national comprehensive cancer network for the treatment of endometrial cancer in Puerto Rico.

BACKGROUND: Endometrial cancer poses a significant health concern in Puerto Rico, where it ranks as the primary gynecological malignancy among women. This study evaluates concordance with the National Comprehensive Cancer Network (NCCN) guidelines for endometrial cancer first treatment in Puerto Rican women and its association with 5-year overall survival. METHODS: Data on patients with endometrial cancer diagnosed between 2009 and 2015 was obtained from the Puerto Rico Central Cancer Registry, which is linked to the Puerto Rico Health Insurance Linkage database (n = 2114). The association between receiving guideline-concordant first treatment and clinical, socioeconomic, and health system factors was evaluated using logistic regression. The 5-year overall survival was calculated using the Kaplan-Meier method. Cox proportional hazard regression models were used to estimate hazard ratios and 95 % confidence intervals (CIs) for associations between guideline-concordant first treatment and overall survival. RESULTS: In our cohort, 53.9 % of patients received guideline-concordant first treatment. Receiving care at a Commission on Cancer-accredited center, being evaluated by a gynecologist-oncologist, and possessing private insurance enhanced the likelihood of receiving guideline-concordant first treatment. In the Cox regression models, receiving guideline-concordant first treatment was associated with a lower mortality risk (HR: 0.72, 95 % CI: 0.59-0.89). CONCLUSION: Guideline-concordant first treatment is a strong predictor of improved survival rates in endometrial cancer. Given that guidelines based on scientific evidence have been demonstrated to enhance patient outcomes, we must understand and promote the factors contributing to their adoption.

Expanding Diagnostic Workup for hypertensive Intracerebral hemorrhage: a retrospective LATAM cerebrovascular registry comparison.

Background: The leading cause of spontaneous intracerebral hemorrhage (ICH) is hypertensive arteriolopathy. In addition to age and hypertension history, patients usually present other comorbidities that potentially increase morbimortality. Ancillary studies other than non-contrast computerized tomography (NCCT) may help clarify the diagnosis and increase the detection of potentially modifiable vascular risk factors. Unfortunately, their use is not routinely performed. Objective: The study aimed to determine the frequency of ancillary studies performed in patients with hypertensive ICH. Methods: We performed a retrospective analysis of three Latin American cerebrovascular registries from academic medical centers, analyzing the results with descriptive statistics focusing on diagnosis and short-term outcomes. Results: We analyzed a total of 1,324 patients (mean age 64 years). Hypertension and obesity were the most prevalent risk factors. Only 14% underwent MRI, 10.3% extracranial ultrasonography, and 6.7% echocardiography. Among the three registries, the Latin America Stroke Registry performed more ancillary studies. Most of the patients presented a poor clinical outcome and in-hospital death. Conclusions: The use of ancillary studies in the diagnostic workup of ICH was poor in the three registries, and mortality was high. The lack of ancillary studies performed may negatively impact outcomes.

First year report of the IMSS Multicenter Hip Fracture Registry.

The population has aged; there is a greater risk of osteoporosis and hip fracture. We describe the standards of care for hip fractures in various hospitals of Mexico. A total of 1042 subjects participated. The acute mortality was 4.3%. SIGNIFICANCE: Hip fracture registries provide a means to compare care and establish improvement processes. BACKGROUND: The Mexican population has aged; thus, there is a greater risk of osteoporosis, and its main consequence is hip fracture due to fragility. Its incidence is high, and it is expected to increase due to aging in our country. International guidelines provide standardized recommendations for the care of people with hip fractures, while hip fracture registries provide a means to compare care with local, national, and international clinical standards and establish improvement processes. OBJECTIVE: Describe the standards of care for hip fractures in various hospital centers of the Mexican Social Security Institute. METHODS: This was an observational, multicenter, longitudinal, and descriptive study. It included 24 hospital centers in Mexico. Informed consent was obtained. Data were recorded during the hospital stay, epidemiological data, and management, and follow-up was carried out 30 and 120 days after discharge. The information was analyzed using SPSS version 22.0. RESULTS: A total of 1042 subjects aged 79.5 ± 7.6 years participated, mostly women (n = 739; 70.9%) from the community (n = 1,021; 98.0%) and with functional independence (Barthel 80.9 ± 22.2). The transfer time to the emergency room was 4.6 ± 14.6 days. Pertrochanteric hip fracture was the most common (n = 570, 54.7%). The most common type of procedure was dynamic hip screw (DHS) (n = 399; 40.1%). Documented thromboprophylaxis was granted in 91.5% (n = 953) and antibiotic prophylaxis in 53.0% (n = 552) of the patients. The goal of 36 h for the surgical procedure was achieved in 7.6% of the subjects (n = 76), with the most frequent cause being a delay in scheduling (n = 673, 67.6%). The mean time from emergency room to surgery was 7.8 ± 7.0 days. The acute mortality rate was 4.3%. Secondary pharmacologic prevention upon discharge occurred in 64.2% of patients. At 30 days, 370 subjects (37.1%) were lost to follow-up, with a mortality of 3%, while at 120 days, 166 subjects (27.8%) were lost, with a mortality of 2.8%. CONCLUSION: In the hospital centers where the study was carried out, there are still no standards of care for hip fractures, which makes it necessary to rethink the care for this population group through a strategy focused on meeting those standards.

Electrophysiology lab efficiency using cryoballoon for pulmonary vein isolation in Latin America: A sub-analysis of the Cryo Global Registry Study.

Objective: Cryoballoon ablation for pulmonary vein isolation is a time-efficient procedure that can alleviate stress on electrophysiology lab resources. This analysis modeled the impact of cryoballoon ablation on electrophysiology lab operation using data from Latin America. Methods: Data from centers in Argentina, Mexico, Colombia, and Chile of the were used as inputs for an electrophysiology lab efficiency simulation model. The model used the assumption that either two (today's electrophysiology lab operations) or three (including electrophysiology lab operational changes) cryoballoon ablation procedures could be performed per day. The endpoints were the percentage of days that resulted in 1) overtime and 2) time left for an extra non-ablation electrophysiology procedure. Results: Data from a total of 232 procedures from six Latin American centers were included in the analysis. The average electrophysiology lab occupancy time for all procedures in Latin America was 132 ± 62 minutes. In the Current Scenario (two procedures per day), 7.4% of simulated days resulted in overtime, and 81.4% had enough time for an extra electrophysiology procedure. In the Enhanced Productivity Scenario (three procedures per day), 16.4% of days used overtime, while 67.4% allowed time for an extra non-ablation electrophysiology procedure. Conclusions: Using real-world, Latin American-specific data, we found that with operational changes, three ablation procedures could feasibly be performed daily, leaving time for an extra electrophysiology procedure on more than half of days. Thus, use of cryoballoon ablation is an effective tool to enhance electrophysiology lab efficiency in resource-constrained regions such as Latin America.

Objetivos: La ablación con criobalón para el aislamiento de venas pulmonares es un procedimiento que ahorra tiempo y puede ahorrar recursos del laboratorio de electrofisiología. Este análisis modeló el impacto de la ablación con criobalón en el funcionamiento del laboratorio de electrofisiología utilizando datos de América Latina. Métodos: Los datos de los centros de Argentina, México, Colombia y Chile del se utilizaron como datos de entrada para un modelo de simulación de la eficiencia del laboratorio de electrofisiología. El modelo partió del supuesto de que se podían realizar dos (operaciones actuales del laboratorio de electrofisiología) o tres (incluidos los cambios operativos del laboratorio de electrofisiología) procedimientos de ablación con criobalón por día. Los criterios de valoración eran el porcentaje de días en los que se producían 1) horas extraordinarias y 2) tiempo restante para un procedimiento electrofisiológico adicional no relacionado con la ablación. Resultados: Se incluyeron en el análisis los datos un total de 232 procedimientos de seis centros latinoamericanos. El tiempo medio de ocupación del laboratorio de electrofisiología para todos los procedimientos en Latinoamérica fue de 132 ± 62 minutos. En el escenario actual (dos procedimientos por día), el 7,4% de los días simulados resultaron en horas extras, y el 81,4% tuvo tiempo suficiente para un procedimiento de electrofisiología adicional. En el escenario de productividad mejorada (tres procedimientos por día), el 16,4% de los días utilizó horas extraordinarias, mientras que el 67,4% dispuso de tiempo suficiente para un procedimiento electrofisiológico extra sin ablación. Conclusiones: Utilizando datos del mundo real específicos de América Latina, descubrimos que, aplicando cambios operativos, es factible realizar tres procedimientos de ablación al día, lo que deja tiempo para un procedimiento de electrofisiología adicional en más de la mitad de los días. Por lo tanto, el uso de la ablación con criobalón es una herramienta eficaz para mejorar la eficiencia de los laboratorios de electrofisiología en regiones con recursos limitados como América Latina.

Update on the Epimed Monitor Adult ICU Database: 15 years of its use in national registries, quality improvement initiatives and clinical research.

In recent decades, several databases of critically ill patients have become available in both low-, middle-, and high-income countries from all continents. These databases are also rich sources of data for the surveillance of emerging diseases, intensive care unit performance evaluation and benchmarking, quality improvement projects and clinical research. The Epimed Monitor database is turning 15 years old in 2024 and has become one of the largest of these databases. In recent years, there has been rapid geographical expansion, an increase in the number of participating intensive care units and hospitals, and the addition of several new variables and scores, allowing a more complete characterization of patients to facilitate multicenter clinical studies. As of December 2023, the database was being used regularly for 23,852 beds in 1,723 intensive care units and 763 hospitals from ten countries, totaling more than 5.6 million admissions. In addition, critical care societies have adopted the system and its database to establish national registries and international collaborations. In the present review, we provide an updated description of the database; report experiences of its use in critical care for quality improvement initiatives, national registries and clinical research; and explore other potential future perspectives and developments.

Factors associated with delayed initiation of breast cancer treatment at an oncology referral center in Juiz de Fora, Minas Gerais state, from 2010 to 2019: a cohort study.

OBJECTIVES: To analyze factors associated with delayed initiation of breast cancer treatment at an oncology referral center in Juiz de Fora, Minas Gerais state, between 2010 and 2019. METHODS: This was a cohort study using data from the Hospital-based Cancer Registry. The probability of not starting treatment within 60 days, in accordance with Brazilian law, was estimated using Kaplan-Meier, method and its association with the factors studied was assessed using the Cox model, presenting hazard ratios (HR) and respective 95% confidence intervals (95%CI). RESULTS: Among the 911 participants, the probability of delayed treatment initiation was 18.8% (95%CI 16.4;21.5). Those who underwent treatment at a health service other than the one where the cancer was diagnosed had a significantly higher risk (HR: 3.49; 95%CI 3.00;4.07). CONCLUSION: Receiving a diagnosis and treatment at the same institution may help reduce waiting time to initiate cancer treatment. MAIN RESULTS: The probability of study participants not initiating treatment within 60 days was 18.8%. Undergoing treatment at a healthcare service other than the one where the diagnosis was made was the main factor associated with delay. IMPLICATIONS FOR SERVICES: Organizing healthcare services based on strategies that optimize referral flows and avoid transitions of care, can be crucial in reducing the time to initiation of breast cancer treatment. PERSPECTIVES: It is essential to improve the workflows at the different stages of health care to ensure timely initiation of oncological treatment.

Recent cervical cancer incidence, stage at diagnosis, and mortality trends in Puerto Rico, 2001-2019.

BACKGROUND: Cervical cancer incidence is rising in Puerto Rico (PR). Whether the increase is real or reflective of increased diagnostic scrutiny remains unclear. METHODS: Using data from the PR Central Cancer Registry for 2001-2019, we estimated trends of hysterectomy-corrected cervical cancer incidence and mortality rates, overall, and by stage at diagnosis and age. RESULTS: Overall, cervical cancer incidence (per 100,000) increased 1.6%/year (95% CI, -0.5% to 3.8%) from 12.5 to 15.3, with a prominent increase in distant-stage disease (4.5%/year [95% CI, 1.6% to 8.0%]), particularly among screening age eligible (25-64-year-old) women (5.8%/year [95% CI, 2.1% to 10.6%]). Mortality rates in this age-group remained stable during the study period. CONCLUSIONS: Increased occurrence of distant-stage disease among screening-eligible women is troubling and may reflect a real increase. Future research is needed to elucidate the factors underlying these trends. Improved prevention is also an urgent priority to reverse the rising cervical cancer incidence in PR.

Impact of sex on clinical and laboratory parameters in patients with heart failure: insights from the Colombian Heart Failure Registry (RECOLFACA).

INTRODUCTION: Heart failure (HF) is one of the leading causes of morbidity and mortality worldwide. This study aimed to assess the impact of sex on sociodemographic, clinical, and laboratory parameters in patients with HF who were included in the Colombian Heart Failure Registry (RECOLFACA). METHODS: This was a cross-sectional analytical research. All 2528 patients included in RECOLFACA were analysed. The Mann-Whitney U test was used to compare median values as well as first and third quartiles (Q1-Q3). The age-related trend of NT-proBNP levels for both men and women groups was statistically evaluated. RESULTS: The study included 2528 patients with HF (1072 women and 1456 men). The echocardiographic evidence showed that men presented reduced left ventricular ejection fraction (LVEF) (79.63 vs. 69.75%, respectively; p < 0.001) more often than women, which had a significantly higher proportion of preserved LVEF (20.46 vs.11.24%, respectively; p < 0.001). Women displayed a higher value of systolic blood pressure (p < 0.001) and heart rate (p = 0.014) compared to men. Haemoglobin, creatinine, and sodium levels were significantly higher in men. Men had a considerably lower glomerular filtration rate value, with the median reaching a G3a value for chronic renal failure. According to age, the levels of NT-proBNP in each sex increased equivalently with age. CONCLUSION: Sex differences presented in this study are comparable to those discovered in other nations. However, certain variations show that these sex differences may differ by geographical area, which should encourage further investigations to describe them.

Characteristics, treatment and prognosis of patients with chronic heart failure according to ejection fraction. Results of an Ecuadorian registry.

BACKGROUND: In Ecuador, there are few data about the clinical behaviour of heart failure (HF). This study aims to analyse the clinical characteristics, treatment and prognosis according to the current classification based on left ventricular ejection fraction (EF). METHODS: A retrospective observational study was carried out in patients with chronic HF from the 'Los Ceibos' registry during the period January 2017-December 2022. Patients were classified into HF with preserved EF (HFpEF) [EF ≥ 50%], HF with mildly reduced EF (HFmrEF) [EF:41-49%], and HF with reduced (HFrEF) [EF ≤ 40%]. The patients were followed up for a mean time of 2.28 (IQR 1.25-3.49) years. RESULTS: A total of 711 patients were included, 333 (46.8%) with HFrEF, 109 patients (15.3%) with HFmrEF and 269 patients (37.8%) with HFpEF. The average age was 69.8 ± 13.1 years, 31.4% were women. The main comorbidity was arterial hypertension (92.7%). Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers were used in 74.5%, beta-blockers in 82.3%, and mineralocorticoid receptor antagonists in 51.3%. 58.3% of patients with HFrEF received three drugs of the so-called foundational quadruple therapy. A lower all-cause (24.5%) and cardiovascular mortality rate (11,2%) was observed in the HFpEF group compared to HFmrEF (47.4% and 25,7%) and HFrEF (45.3% and 25,8%), p < 0.001. CONCLUSIONS: In the 'Los Ceibos' registry, a higher prevalence of HFrEF was observed. The main comorbidity was HTN. Half of the patients with HFrEF received three drugs of the foundational therapy. At four years of follow-up, lower all-cause and cardiovascular mortality rate was observed in the HFpEF group.

[Analysis of the unicentric registry of the Infarction Code program: retrospective cohort]. / Análisis del registro unicéntrico del programa Código Infarto: cohorte retrospectiva.

Background: Acute coronary syndrome (ACS) is the most serious manifestation of coronary heart disease. The Infarction Code (according to its initialism in Spanish, CI: Código Infarto) program aims to improve the care of these patients. Objective: To describe the clinical presentation and outcomes of CI program in a coronary care unit (CCU). Material and methods: A database of a CCU with 5 years of consecutive records was analyzed. Patients diagnosed with ACS were included. The groups with acute myocardial infarction with and without ST-segment elevation were compared using Student's t, Mann-Whitney U and chi-squared tests. We calculated the relative risk (RR) and 95% confidence intervals (95% CI) of cardiovascular risk factors for mortality. Results: A total of 4678 subjects were analyzed, 78.7% men, mean age 63 years (± 10.7). 80.76% presented acute myocardial infarction with positive ST-segment elevation and fibrinolytic was granted in 60.8% of cases. Percutaneous coronary intervention was performed in 81.4% of patients, which was successful in 82.5% of events. Patients classified as CI presented mortality of 6.8% vs. 11.7%, p = 0.001. Invasive mechanical ventilation had an RR of 26.58 (95% CI: 20.61-34.3) and circulatory shock an RR of 20.86 (95% CI: 16.16-26.93). Conclusions: The CI program decreased mortality by 4.9%. Early fibrinolysis and successful coronary angiography are protective factors for mortality within CCU.

Introducción: el síndrome coronario agudo (SICA) es la manifestación más grave de la enfermedad coronaria. El programa Código Infarto (CI) tiene como objetivo mejorar la atención de estos pacientes. Objetivo: describir la presentación clínica y los resultados del programa CI de una unidad de cuidados coronarios (UCC). Material y métodos: se analizó una base de datos de una UCC con 5 años de registros consecutivos. Se incluyeron pacientes con diagnóstico de SICA. Se compararon los grupos con infarto agudo de miocardio con y sin elevación del segmento ST mediante las pruebas t de Student, U de Mann-Whitney y chi cuadrada. Se calculó el riesgo relativo (RR) y el intervalo de confianza del 95% (IC 95%) de los factores de riesgo cardiovascular para mortalidad. Resultados: se analizaron 4678 sujetos, 78.7% hombres, con media de edad de 63 años (± 10.7). El 80.76% presentó infarto agudo de miocardio con desnivel positivo del segmento ST y se otorgó fibrinolítico en el 60.8% de los casos. Se realizó intervencionismo coronario percutáneo en el 81.4% de los pacientes, el cual fue exitoso en el 82.5% de los eventos. Los pacientes catalogados como CI presentaron mortalidad del 6.8% frente a 11.7%, p = 0.001. La ventilación mecánica invasiva tuvo una RR de 26.58 (IC 95%: 20.61-34.3) y el choque circulatorio una RR de 20.86 (IC 95%: 16.16-26.93). Conclusiones: el programa CI disminuyó 4.9% la mortalidad. La fibrinólisis temprana y la angiografía coronaria exitosa son factores protectores para mortalidad dentro de la UCC.

Clinical, epidemiological, and care profile of hospitalized patients with retinoblastoma in Brazil.

PURPOSE: To describe the epidemiological and clinical profile of hospitalized patients with retinoblastoma in Brazil. METHODS: Using data from the Hospital Cancer Registry of the Instituto Nacional de Câncer, patients with the morphological codes of retinoblastoma who were diagnosed between 2000 to 2018, aged 0-19 years, and followed up in registered hospitals (analytical cases) were selected. The relative and absolute frequencies of demographic, clinical, diagnostic, therapeutic, and outcome variables were described. Hospital performance indicators were calculated and compared between hospitals qualified and not qualified to treat pediatric oncology cases and between hospitals with different case volumes (<20, 20-75, >75 cases). RESULTS: Of the 2,269 identified analytical cases from 86 institutions, 48% were from the Southeast, 54% were male, and 66% were aged <4 years. The proportion of missing data (NA) was too high for several variables. Approximately 84% of the patients were from the public health system, 40% had a positive family history, and 88% had unilateral involvement. The first treatment included surgery in 58.3% of the patients (NA=2), Approximately 36.6% of these patients achieved complete remission, 10.8% achieved partial remission, and 12.7% died (NA=59%). Hospital performance indicators were within the target in >90% of the patients. The median time between the first appointment and diagnosis (6 days, interquartile range [IQR] 1-14) was significantly lower and the median time to death was longer (343 days, IQR, 212-539) in high-volume hospitals (>75 cases) than in medium- and low-volume hospitals. CONCLUSIONS: Despite the high proportion of missing data, we found that the delay in diagnosis is due to prehospital factors. Additionally, there is a need for educational programs for healthcare professionals and families that emphasize early identification and referral to specialized centers. Future studies should focus on the impact of Hospital Cancer Registry data completeness on outcomes, causes of delay in diagnosis, regional inequalities, and barriers to accessing specialized services.
