Children with cancer at the end of life in a middle-income country: integrated pediatric palliative care improves outcomes.

BACKGROUND: In 2020, the Global Cancer Observatory reported 280,000 cases of childhood cancer worldwide, with a higher burden of disease and mortality rates in low- and middle-income countries. In 2022, the National Institute of Health reported 1708 new cases of childhood cancer in Colombia and an overall survival rate of approximately 55%. The aim of this study is to compare outcomes in children with cancer in the hospital setting during the last 72 h of life who received concurrent Pediatric Palliative Care (PPC) versus oncology care alone. METHODS: An observational descriptive study was conducted between January 2013 and June 2022 in a center for pediatric patients with oncological diagnoses. In 2017, the PPC team was created. Patients between 28 days and 17 years of age who were hospitalized at least 72 h before death were included. A retrospective review of the medical records of patients in the last 72 h of life was performed. Two cohorts were established: oncology-alone group received exclusive management by oncology, and oncology and PPC received concurrent oncology and PPC management since the diagnosis. RESULTS: We evaluated 257 medical records of deceased pediatric patients with cancer diagnoses. For the first cohort (2013-2017), 136 patients were included; for the second cohort (2018 and 2022), 121 patients were evaluated. The most frequent diagnosis was leukemia [47.1% (n = 121)]. No significant difference was found in either group between dyspnea, pain, and seizures. Dyspnea was the most frequent symptom in both groups. Agitation and anxiety were reported more frequently in children from the oncology-alone group (22.1% and 13.2%, respectively). The oncology and PPC group received more psychology and social work consultation (94.2% and 70.2% vs. 84.6 and 54.4% in the oncology alone group) and had a higher percentage of advance care planning (79.3% vs. 62.5% in the oncology alone group). CONCLUSIONS: This retrospective study highlights that PPC at the end of life (EoL) offers a holistic approach to the physical and psychosocial symptoms experienced by children with cancer; these patients received more comfort through symptom management and less aggressive treatment at the EoL. The availability of a PPC team may contribute to improvements in the quality of end-of-life care. TRIAL REGISTRATION: retrospectively registered.

Discordancia entre pruebas de susceptibilidad genotípicas y fenotípicas para tuberculosis en Cali, Colombia: un reto en la práctica clínica

Introducción: La detección de patrones de resistencia de Mycobacterium tuberculosis se basa en pruebas de susceptibilidad fenotípicas y genotípicas. Los resultados discordantes entre ellas son un desafío clínico para el manejo de pacientes con tuberculosis resistente a fármacos. Objetivo: Evaluar la concordancia entre pruebas fenotípicas y moleculares en pacientes con tuberculosis resistente a fármacos atendidos en una institución de Cali, Colombia. Materiales y Métodos: Se realizó un estudio transversal en el que se obtuvo el perfil de sensibilidad fenotípico de cultivos de micobacterias y la susceptibilidad genotípica con las pruebas moleculares Xpert-MTB/ RIF® o Genotype-MDRTBplus ®. Se evaluó el porcentaje de resistencia y porcentaje de acuerdo entre los resultados de las pruebas fenotípicas y genotípicas. Se estimó un coeficiente de kappa de Cohen (κ) para cada tipo de resistencia según la prueba utilizada. Resultados: Se incluyeron 30 casos con resultados de pruebas genotípicas y fenotípicas. Las pruebas fenotípicas detectaron resistencia a fármacos de primera línea en 29/30 casos, mientras que las moleculares detectaron la resistencia en todos los casos evaluados. El porcentaje de resistencia a rifampicina detectado entre la prueba fenotípica y Genotype-MDRTBplus ® &e 61,5% (acuerdo global 41,1%, κ = 0,40, p = 0,96), mientras que el porcentaje de resistencia detectado con Xpert-MTB/RIF® fue 100% (acuerdo global 81,82%, κ: 0,00, p < 0,001) para este mismo medicamento. El porcentaje de resistencia a isoniacida detectado entre la prueba fenotípica y Genotype-MDRTBplus ® fue 94,4% (acuerdo global 89,47%, κ: -0,055 p = 0,59). Conclusiones: La discordancia entre los resultados de las pruebas genotípicas y fenotípicas es posible, por lo que es importante usar e interpretar ambos tipos de pruebas de manera complementaria en el diagnóstico de la resistencia a fármacos de primera línea en la infección por M. tuberculosis.

Background: The detection of Mycobacterium tuberculosis resistance patterns is based on phenotypic and genotypic susceptibility tests. The discordant results between them are a clinical challenge for the management of patients with drug-resistant tuberculosis. Aim: To evaluate the concordance between phenotypic and molecular tests in patients with drug-resistant tuberculosis treated in an institution in Cali, Colombia. Methods: A cross-sectional study was conducted. A phenotypic sensitivity profile was obtained from mycobacterial cultures. The genotypic susceptibility was obtained with Xpert-MTB/ RIF® or Genotype-MDRTBplus ®. The percentage of resistance and percentage of agreement between the results of the phenotypic and genotypic tests were evaluated. A Cohen's kappa coefficient (κ) was estimated for each type of resistance according to the test used. Results: A total of 30 cases with both genotypic and phenotypic testing were included. The phenotypic tests detected resistance to first-line drugs in 29/30 cases, while the molecular tests detected resistance in all the cases evaluated. The percentage of resistance detected between Genotype-MDRTBplus® and the phenotypic test for rifampicin was 61.5% (overall agreement 41.1%, κ = 0.40, p = 0.96), while the percentage of resistance detected with XpertMTB/RIF® was 100% (overall agreement 81.82%, κ: 0.00, p < 0.001) for this same drug. Resistance to isoniazid detected by both types of tests was 94.4% (overall agreement 89.47%, κ: -0.055 p = 0.59). Conclusions: Discordance between the results of genotypic and phenotypic tests is possible, so it is important to use and interpret both types of tests in a complementary way in the diagnosis of resistance to first-line drugs in M. tuberculosis infection.

Conocimientos, prácticas y actitudes del manejo programático de la tuberculosis en estudiantes de medicina de Colombia / Knowledge, practices and attitudes of the programmatic management of tuberculosis among Colombian medical students

Introducción: La tuberculosis es una enfermedad infecciosa con alta carga de la enfermedad en Colombia, por lo que se espera que la educación médica sea estándar en todas las regiones y los estudiantes de medicina tengan competencias en el manejo operativo de la tuberculosis. Este estudio evaluó los conocimientos, actitudes y prácticas en tuberculosis en estudiantes de medicina de Colombia y los factores relacionados. Métodos: Cuestionario de evaluación de conocimientos, actitudes y prácticas en tuberculosis en estudiantes de medicina en Colombia, que cursaban semestre clínico y se encontraban inscritos en la reunión anual 2020 de la Asociación de Sociedades Científicas de Estudiantes de Medicina de Colombia (ASCEMCOL) para establecer el nivel de conocimientos en tuberculosis. Resultados: Se evidenció que los estudiantes de regiones con mayor carga de la enfermedad como el Eje Cafetero presenta puntajes más altos de forma diferencial a las otras regiones. Por otra parte, se observó que la experiencia propia del estudiante en el tamizaje para tuberculosis (prueba cutánea de la tuberculina PPD - Mantoux) y la experiencia en la atención de pacientes con tuberculosis en el entorno clínico están relacionadas a los conocimientos del manejo programático de la tuberculosis. Conclusión: El estudio demuestra bajo nivel de conocimientos, actitudes y prácticas del manejo programático de la tuberculosis en los estudiantes de medicina que cursaban semestres clínicos en Colombia. (AU)

Background: The tuberculosis is an infectious disease with high disease burden in Colombia, so medical education is expected to be standard in all regions and medical students have competencies in the operative management of tuberculosis. This study evaluated the knowledge, attitudes, and practices in tuberculosis in medical students in Colombia and related factors. Methods: Questionnaire for the evaluation of knowledge, attitudes, and practices in tuberculosis in medical students in Colombia, who were in clinical semesters and were registered at the 2020 annual meeting of the Asociación de Sociedades Científicas de Estudiantes de Medicina de Colombia (ASCEMCOL) to establish the level of knowledge in tuberculosis. Result: The study found that students from regions with a higher burden of disease, such as the Eje Cafetero had higher scores that those from other regions. On the other hand, it was observed that the student´s own experience in tuberculosis screening (tuberculin skin test PPD – Mantoux) and the clinical experience in care patients with tuberculosis are related to the knowledge of the programmatic management of tuberculosis. Conclusions: The study shows a low level of knowledge, attitudes, and practices of programmatic management of tuberculosis in medical students in clinical semester in Colombia. (AU)

Survival in Elderly Patients Diagnosed With Acute Myeloid Leukemia: A Hospital-Based Study.

Background: Acute myeloid leukemia (AML) is a hematological neoplasm that is more frequent in elderly patients. The objective of this study was to evaluate elderly patients' survival with de novo AML and acute myeloid leukemia myelodysplasia-related (AML-MR), treated with intensive and less-intensive chemotherapy and supportive care. Methods: A retrospective cohort study was conducted in Fundacion Valle del Lili (Cali, Colombia), between 2013 and 2019. We included patients ≥ 60 years old diagnosed with AML. The statistical analysis considered the leukemia type (de novo vs. myelodysplasia-related) and treatment (intensive chemotherapy regimen, less-intensive chemotherapy regimen, and without chemotherapy). Survival analysis was performed using Kaplan-Meier method and Cox regression models. Results: A total of 53 patients were included (31 de novo and 22 AML-MR). Intensive chemotherapy regimens were more frequent in patients with de novo leukemia (54.8%), and 77.3% of patients with AML-MR received less-intensive regimens. Survival was higher in the chemotherapy group (P = 0.006), but with no difference between chemotherapy modalities. Additionally, patients without chemotherapy were 10 times more likely to die than those who received any regimen, independent of age, sex, Eastern Cooperative Oncology performance status, and Charlson comorbidity index (adjusted hazard ratio (HR) = 11.6, 95% confidence interval (CI) 3.47 - 38.8). Conclusions: Elderly patients with AML had longer survival time when receiving chemotherapy, regardless of the type of regimen.

Using EmPalPed-An Educational Toolkit on Essential Messages in Palliative Care and Pain Management in Children-As a Strategy to Promote Pediatric Palliative Care.

Background: Most children needing palliative care (PC) live in low- and middle-income countries. In Colombia, pediatric palliative care (PPC) knowledge among healthcare professionals (HCPs) is lacking as PPC is not included in the educational curricula of healthcare programs. Therefore, specific training that improves knowledge of HCPs and access to PC for children and their families is needed. To address this gap, we organized and conducted the Essential Messages in Palliative Care and Pain Management in Children (EmPalPed), an educational toolkit to increase awareness and promote essential knowledge in PPC for low- and middle-income countries. Methodology: The EmPalPed toolkit consisted of a 5-h virtual workshop with small working groups of HCPs caring for children with life-threatening conditions such as cancer. The toolkit was organized along five key domains: (1) PC as it relates to the concept of quality of life (QoL), (2) effective communication, (3) addressing pain management as a top priority, (4) providing end-of-life care, and (5) access to high-quality PC as a fundamental human right. The workshop activities included different educational strategies and tools (e.g., a pocket guide for pain assessment and management, a PPC booklet, a quick guide for communicating bad news, role playing, and discussions of clinical cases). Results: A total of 145 HCPs from 22 centers were trained. The post-test analysis for HCPs showed that attitude and knowledge about communication (p < 0.001), pain assessment (p < 0.001), first-line opioid of choice in children (p < 0.001), and palliative sedation (p < 0.001) had positive and statistically significant changes from the pre-test analysis. Discussion: This study supported the notion that the EmPalPed educational toolkit is an effective mechanism for raising awareness regarding PPC as well as providing training in many of the key aspects of PPC. The EmPalPed training approach should be studied beyond this setting, and the impact should be measured longitudinally.

Challenges of dengue and coronavirus disease 2019 coinfection: two case reports.

BACKGROUND: Dengue fever and coronavirus disease 2019 have now begun to overlap within tropical and subtropical regions. This is due to the high prevalence of dengue fever in these regions and the current severe acute respiratory syndrome coronavirus 2 pandemic situation. The similarity of symptoms between the two diseases can confuse diagnoses, but coinfection can also occur. CASE PRESENTATION: We present two cases of patients with dengue and severe acute respiratory syndrome coronavirus 2 coinfection. The first case is that of a 24-year-old Hispanic woman with acute fever, odynophagia, and diarrhea, without respiratory symptoms and with positive molecular tests for both dengue and severe acute respiratory syndrome coronavirus 2. The second case is that of a 59-year-old Hispanic male patient with fever and respiratory symptoms of 2 weeks duration, negative molecular tests, and positive serological tests for both viruses. The clinical and epidemiological characteristics of both viral infections can help elucidate diagnoses and prognoses. CONCLUSIONS: Severe dengue infection is common in young adults, while coronavirus disease 2019 is generally asymptomatic. In older people, the severity of dengue fever will depend on their comorbidities or the infectious serotype, but coronavirus disease 2019 is consistently more severe in this group. The accurate diagnosis of both infections can better guide clinical management, as well as public health actions in transmission control, now especially important during the coronavirus disease 2019 pandemic.

Impact of Dengue Rapid Diagnostic Tests on the Prescription of Antibiotics and Anti-Inflammatory Drugs by Physicians in an Endemic Area in Colombia.

There is insufficient evidence on whether dengue rapid diagnostic tests (dRDTs) influence clinical decisions in endemic areas. Therefore, our objective was to evaluate the impact of dRDTs on the prescription of antibiotics and anti-inflammatory drugs by physicians in a dengue-endemic area in Colombia. A retrospective cohort study was conducted with 330 patients in Cali, Colombia, between January 2012 and December 2017. The exposure was defined by the result of the dRDT. The outcomes were prescription of antibiotics and anti-inflammatory drugs after results of dRDT. Incidence and RR with 95% CIs were estimated. Multivariate logistic regression models were fitted separately for each outcome. Antibiotics were prescribed in 3% exposed and 14% unexposed. Anti-inflammatory drugs were prescribed in 1.2% exposed and 7.9% unexposed. A positive dRDT reduced the prescription of anti-inflammatories (AdjOR: 0.06, 95% CI: 0.008-0.5) but, by itself, had no effect on antibiotics (AdjOR: 1.1, 95% CI: 0.2-6); however, in hospitalized patients, a positive result reduced the probability of antibiotic prescription (AdjOR: 0.02, 95% CI: 0.00-0.8). Despite limitations of current dRDTs, they influence treatment decisions. Further studies are needed to assess the effect of dRDTs in patient outcomes and health-care costs.
