RESUMO
OBJECTIVES: We determined the validity and reliability of the Spanish translation Sheffield Profile for Assessment and Referral for Care (SPARC-Sp) questionnaire to identify the palliative care (PC) needs of patients with chronic noncommunicable diseases (NCDs) in Colombia. METHODS: We developed a cross-sectional observational study of scale assessment in adults with the aim of determining the validity and reliability of the SPARC-Sp questionnaire to identify the PC needs of patients with NCDs receiving outpatient or inpatient care at the Hospital Universitario San Jose of Popayan - ESE, Colombia, from 2021 to 2022. RESULTS: We applied a questionnaire consisting of demographic, clinical data, and SPARC-Sp to 507 participants. The constructed model explained 75% of the variance with an adequate fit according to the root mean square residual (0.03), the comparative fit index (0.98), and acceptable reliability (McDonald's total omega 0.4-0.9). Opportunities for improvement are the reformulation and inclusion of particular words to improve the representativeness and clarity of the domains of communication and information, religious, and spiritual issues. SIGNIFICANCE OF RESULTS: This research represents the first validation of SPARC in Spanish. SPARC-Sp is an instrument that allows initiating a conversation of the patient's main needs through a systematic assessment of the patients' main needs. Its psychometric validation demonstrated good fit and acceptable reliability.
RESUMO
Introduction Patients with hematologic malignancies are susceptible hosts for the development of invasive fungal infection (IFI), one of the main life-threatening infectious complications faced by these patients. Currently, we have antifungal prophylaxis strategies and antifungal treatment schemes and we recognize that the main risk factor involved is profound and prolonged neutropenia. D-index and cumulative D-index are quantitative parameters, which determine the magnitude of neutropenia, as a function of duration and depth and their value correlates with the occurrence of IFI. Material and methods A case-control study in patients older than 18 years with acute lymphoblastic leukemia (ALL) was admitted between 2009 and 2019 at the National Cancer Institute for induction, consolidation and salvage chemotherapy. Results A total of 167 patients were included, who received 288 cycles of chemotherapy, the latter were considered the unit of analysis. A generalized estimating equations (GEE) model was designed to analyze correlated data; three quantitative and continuous variables of interest were included in this model: age (years), D-index and deep neutropenia (days). For the population D-index, an odds ratio (OR) = 1.000227 (95% CI 1.0002-1.0004); p < 0.001 was obtained. Conclusion D-index is associated with the development of IFI in patients with ALL, with an exponential increase in OR as the absolute value of the D-index increases.
RESUMO
Introduction: Rheumatoid arthritis activity is evaluated based on a physical examination of each of the joints. However, the joint examination is not standardized, and the techniques are variable and difficult to reproduce due to disagreements among examiners. Objective: To recommend standardized joint examination techniques based on the modified RAND-UCLA appropriateness method. Methods: A review of the literature was conducted to determine the items to be included in the joint examination; subsequently, a consensus of rheumatologists was achieved with the modified RAND-UCLA methodology to issue the recommendations. The diagnosis of RA and differential diagnoses were excluded. Results: Two hundred fifteen rheumatologists were invited to participate. Five were included in the core group and 26 in the group of clinical experts. Clinical experience ranged between 2 and 25 years (mean 15.6 years; standard deviation 6.3 years). Most rheumatologists participated in all rounds (Round 1: 100%, Round 2: 61%, and Round 3: 61%). Of the 45 statements in the questionnaire assessing the examination techniques, 28 (62%) were retained. In addition, 6 other statements were included during the face-to-face meeting for a total of 34 final statements. Conclusion: Physical examination techniques for joints that determine RA activity are heterogeneous and differ markedly in terms of several characteristics. A list of recommendations is proposed as a guide to improve and standardize the method for the physical examination of the joints. This standardization will improve the diagnosis and results for patients with RA and help health caregivers provide better treatment.
RESUMO
AIMS: To describe real-life experience with sensor-augmented pump therapy with predictive low-glucose management (SAPT-PLGM), in terms of hypoglycemia and glycemic control after one year of follow-up in T1D patients with hypoglycemia as the main indication of therapy. METHODS: Retrospective cohort study under real life conditions. Baseline and one-year follow-up variables of glycemic control, hypoglycemia and glycemic variability were compared. RESULTS: Fifty patients were included, 31 on prior treatment with SAPT with low-glucose suspend (LGS) feature and 19 on multiple dose insulin injections (MDI). Mean HbA1c decreased in the MDI group (8.24%-7.08%; pâ¯=â¯0.0001). HbA1c change was not significant in the SAPT-LGS group. Area under the curve (AUC) below 70â¯mg/dl improved in both SAPT-LGS and MDI groups while AUC, %time and events below 54â¯mg/dl decreased in SAPT-LGS group. Glycemic variability improved in the MDI group. Less patients presented severe hypoglycemia with SAPT-PLGM in both groups, however the change was non-significant. CONCLUSIONS: Under real life conditions, SAPT-PLGM reduced metrics of hypoglycemia in patients previously treaded with MDI and SAPT-LGS without deteriorating glycemic control in SAPT-LGS patients, while improving it in patients treated with MDI.

In addition to previously studied immunological variables, the relative expression of IFNGR2, IFNAR1, CD18, and CD275 (all encoded in chromosome 21) on circulating leucocytes and multifunctional T cells (evaluated by an intracellular cytokine/proliferation assay) were compared between children with Down syndrome (DS) and healthy controls (HC). As previously reported, numbers of lymphocytes, CD4(+) T cells, Treg cells, B cells, and levels of serum IgM were decreased, and levels of IgG and IgA were increased in children with DS. Moreover, the relative expression of CD18 on T and B cells (previously and not previously reported, respectively) were elevated in DS children (p⩽0.01). Age and numbers of B and Treg cells moderately correlated with retrospectively identified infection related hospitalizations (rho: 0.300-0.460, p⩽0.003). Age and the numbers of Treg cells also correlated with prospectively identified infection related hospitalizations. Future studies are necessary to clarify the role of these parameters in the immunity of DS patients.

BACKGROUND: Several studies have shown variations in the prevalence of allergic rhinitis (AR) around the world, and different potential predisposing factors. More studies are needed on risk factors, specifically in developing countries. This study explored the association of several factors and AR among urban residents in six cities of Colombia. METHODOLOGY: A cross-sectional study and a nested case-control study were carried out between 2009 and 2010 involving two Colombian subpopulations: children/adolescents and adults. Cases were affirmative respondents to "In the past 12 months, have you (or your child) had a problem with sneezing or a running or blocked nose, when you (or your child) did not have a cold or the flu?" "Controls" were subjects who never had been diagnosed with asthma, AR or atopic eczema by a physician, and whom did not report any symptoms in the past twelve months. Weighted logistic regression was used to assess the association of different factors with case/control status. RESULTS: Factors associated with AR in children/adolescents were family history of AR, acetaminophen consumption and high socioeconomic status. Among adults, family history of asthma, AR and atopic eczema, and cetaminophen consumption were associated with AR. Consumption of cereals among children/adolescents and eating eggs among adults showed protective associations. CONCLUSIONS: Our findings suggest the presence of previously unknown cultural, environmental and family factors associated with the presence of AR in Colombia.

BACKGROUND: Evaluation of psychosocial factors requires instruments that measure dynamic complexities. This study explains the design of a set of questionnaires to evaluate work and non-work psychosocial risk factors for stress-related illnesses. METHODS: The measurement model was based on a review of literature. Content validity was performed by experts and cognitive interviews. Pilot testing was carried out with a convenience sample of 132 workers. Cronbach's alpha evaluated internal consistency and concurrent validity was estimated by Spearman correlation coefficients. RESULTS: Three questionnaires were constructed to evaluate exposure to work and non-work risk factors. Content validity improved the questionnaires coherence with the measurement model. Internal consistency was adequate (α = 0.85-0.95). Concurrent validity resulted in moderate correlations of psychosocial factors with stress symptoms. CONCLUSIONS: Questionnaires' content reflected a wide spectrum of psychosocial factors sources. Cognitive interviews improved understanding of questions and dimensions. The structure of the measurement model was confirmed.

BACKGROUND: The study of workers' health problems possibly associated with stressful conditions requires valid and reliable tools for monitoring risk factors. The present study validates two questionnaires to assess psychosocial risk factors for stress-related illnesses within a sample of Colombian workers. METHODS: The validation process was based on a representative sample survey of 2,360 Colombian employees, aged 18-70 years. Worker response rate was 90%; 46% of the responders were women. Internal consistency was calculated, construct validity was tested with factor analysis and concurrent validity was tested with Spearman correlations. RESULTS: The questionnaires demonstrated adequate reliability (0.88-0.95). Factor analysis confirmed the dimensions proposed in the measurement model. Concurrent validity resulted in significant correlations with stress and health symptoms. CONCLUSIONS: "Work and Non-work Psychosocial Factors Questionnaires" were found to be valid and reliable for the assessment of workers' psychosocial factors, and they provide information for research and intervention.

BACKGROUND AND OBJECTIVE: It has been suggested that probiotics may decrease infant mortality and nosocomial infections because of their ability to suppress colonization and translocation of bacterial pathogens in the gastrointestinal tract. We designed a large double-blinded placebo-controlled trial using Lactobacillus reuteri to test this hypothesis in preterm infants. METHODS: Eligible infants were randomly assigned during the first 48 hours of life to either daily probiotic administration or placebo. Infants in the intervention group were administered enterally 5 drops of a probiotic preparation containing 10(8) colony-forming units of L reuteri DSM 17938 until death or discharge from the NICU. RESULTS: A total of 750 infants ≤ 2000 g were enrolled. The frequency of the primary outcome, death, or nosocomial infection, was similar in the probiotic and placebo groups (relative risk 0.87; 95% confidence interval: 0.63-1.19; P = .376). There was a trend toward a lower rate of nosocomial pneumonia in the probiotic group (2.4% vs 5.0%; P = .06) and a nonsignificant 40% decrease in necrotizing enterocolitis (2.4% vs 4.0%; P = .23). Episodes of feeding intolerance and duration of hospitalization were lower in infants ≤ 1500 g (9.6% vs 16.8% [P = .04]; 32.5 days vs 37 days [P = .03]). CONCLUSIONS: Although L reuteri did not appear to decrease the rate of the composite outcome, the trends suggest a protective role consistent with what has been observed in the literature. Feeding intolerance and duration of hospitalization were decreased in premature infants ≤ 1500 g.

BACKGROUND: While it is suggested that the prevalence of asthma in developed countries may have stabilized, this is not clear in currently developing countries. Current available information for both adults and children simultaneously on the burden and impact of allergic conditions in Colombia and in many Latin American countries is limited. The objectives of this study were to estimate the prevalence for asthma, allergic rhinitis (AR), atopic eczema (AE), and atopy in six colombian cities; to quantify costs to the patient and her/his family; and to determine levels of Immunoglobulin E (IgE) in asthmatic and healthy subjects. METHODS: We conducted a cross-sectional, population-based study in six cities during the academic year 2009-2010. We used a school-based design for subjects between 5-17 years old. We carried out a community-based strategy for subjects between 1-4 years old and adults between 18-59 years old. Serum samples for total and antigen-specific (IgE) levels were collected using a population-based, nested, case-control design. RESULTS: We obtained information on 5978 subjects. The largest sample of subjects was collected in Bogotá (2392). The current prevalence of asthma symptoms was 12% (95% CI, 10.5-13.7), with 43% (95% CI, 36.3-49.2) reporting having required an emergency department visit or hospitalization in the past 12 months. Physician diagnosed asthma was 7% (95% CI, 6.1-8.0). The current prevalence of AR symptoms was 32% (95% CI, 29.5-33.9), and of AE symptoms was 14% (95% CI, 12.5-15.3). We collected blood samples from 855 subjects; 60.2% of asthmatics and 40.6% of controls could be classified as atopic. CONCLUSIONS: In Colombia, symptom prevalence for asthma, AR and AE, as well as levels of atopy, are substantial. Specifically for asthma, symptom severity and absence from work or study due to symptoms are important. These primary care sensitive conditions remain an unmet public health burden in developing countries such as Colombia.

BACKGROUND: Our main outcome was to identify organizational characteristics that help to evaluate the differences between the intensive care mortality ratios adjusted by APACHE II. We incorporated the variation associated with the ranking of institutions simulating its random effects under a binomial distribution. METHODS: A nationwide survey on structure, technology, and staffing resources available in Colombian intensive care units during 1997-1998 was conducted. We collected data on admissions from 20 randomly selected adult medical and surgical intensive care units. RESULTS: The mortality ratio from the 20 intensive care units ranged from 0.59 to 2.36; 80% of the intensive care units had a mortality ratio greater than 1. All four intensive care units with the lowest mortality ratio belonged to private institutions, while four of five institutions with the highest mortality belonged to the public sector. Intensive care units in private institutions also had fewer number of beds, lower median length of stay, lower occupancy rates, higher education training for specialists and nurses and fewer emergency nonelective surgical procedures. CONCLUSION: We successfully accounted for intensive care mortality baseline differences and random effects variations. There were substantial differences between intensive care units in institution type, bed availability, technology, staffing resources, and degree of training, which may have been associated with patient outcome. These results are of crucial importance to track, detect and assess future changes.

OBJECTIVE: To determine the efficacy and safety of high-frequency oscillatory ventilation (HFOV) compared to conventional ventilation (CV) for the treatment of respiratory failure in term and near-term infants in Colombia. STUDY DESIGN: Eligible infants with moderate to severe respiratory failure were randomized to early treatment with CV or HFOV. Ventilator management and general patient care were standardized. The main outcome was neonatal death or pulmonary air leak. RESULTS: A total of 119 infants were enrolled (55 in the HFOV group; 64 in the CV group) during the study period. Six infants in the HFOV group (11%) and two infants in the CV group (3%) developed the primary outcome (RR: 3.6, 95% CI: 0.8-16.9). Five infants in the HFOV group (9%) and one infant in the CV (2%) died before 28 days of life (RR: 5.9 CI: 0.7-48.2). Secondary outcomes were similar between groups. CONCLUSION: HFOV may not be superior to CV as an early treatment for respiratory failure in this age group. Standardization of ventilator management and general patient care may have a greater impact on the outcome in Colombia than mode of ventilation.

OBJECTIVE: This study was designed to identify risk factors for nosocomial infections among infants admitted into eight neonatal intensive care units in Colombia. Knowledge of modifiable risk factors could be used to guide the design of interventions to prevent the problem. STUDY DESIGN: Data were collected prospectively from eight neonatal units. Nosocomial infection was defined as culture-proven infection diagnosed after 72 hours of hospitalization, resulting in treatment with antibiotics for >3 days. Associations were expressed as odds ratios. Logistic regression was used to adjust for potential confounders. RESULTS: From a total of 1504 eligible infants, 80 were treated for 127 episodes of nosocomial infection. Logistic regression analysis identified the combined exposure to postnatal steroids and H2-blockers, and use of oral gastric tubes for enteral nutrition as risk factors significantly associated with nosocomial infection. CONCLUSION: Nosocomial infections in Colombian neonatal intensive care units were associated with modifiable risk factors including use of postnatal steroids and H2-blockers.

OBJECTIVE: The epidemiology of nosocomial infections (NI) in neonatal intensive care units in developing countries has been poorly studied. We conducted a prospective study in selected neonatal units in Colombia, SA, to describe the incidence rate, causative organisms, and interinstitutional differences. STUDY DESIGN: Data were collected prospectively from February 20 to August 30, 2001 from eight neonatal units. NI was defined as culture-proven infection diagnosed after 72 h of hospitalization, resulting in treatment with antibiotics for >3 days. Linear regression models were used to describe associations between institutional variables and NI rates. RESULTS: A total of 1504 infants were hospitalized for more than 72 h, and therefore, at risk for NI. Of all, 127 infections were reported among 80 patients (5.3%). The incidence density rate was 6.2 per 1000 patient-days. Bloodstream infections accounted for 78% of NIs. Gram-negative organisms predominated over gram-positive organisms (55 vs 38%) and were prevalent in infants < or =2000 g (54%). The most common pathogens were Staphylococcus epidermidis (26%) and Klebsiella pneumonia (12%). CONCLUSION: Gram-negative organisms predominate in Colombia among infants <2000 g. The emergence of gram-negative organisms and their associated risk factors requires further study.

A cohort of intensive care unit (ICU) patients in 20 Colombian ICUs is used to describe the application of three imputation techniques: single, hot deck and multiple imputation. These strategies were used to impute the missing data in the variables used to construct APACHE II scores, a scoring system for the ICU patients that provides an unbiased standardized estimate of the probability of hospital death. Imputed APACHE II scores were then used in the APACHE II model to estimate adjusted hospital mortality rates. The area under the receiver operating characteristic (ROC) curve was used to compare imputation strategies with respect to predictive power. While statistically significant differences were found for the area under the ROC curve, these differences were not clinically significant.

Clínicos, investigadores y en especial epidemiólogos, frecuentemente se enfrentan al problema de tener datos faltantes en las bases de datos de sus estudios. Muchas técnicas estadísticas existen para dar solución a este problema, como por ejemplo el análisis de casos completos y la imputación de datos. Sin embargo, estas técnicas no siempre se implementan en los análisis principalmente por su desconocimiento o por la ausencia de paquetes computacionales con este tipo de aplicaciones. El presente trabajo desarrolla una descripción de tres de las técnicas de manejo de valores faltantes más utilizadas. El objetivo principal es mostrar las ventajas de una técnica novedosa para el tratamiento de los datos faltantes conocida como imputación múltiple. Con el fin de ilustrar al lector, al final se presenta su aplicabilidad mediante el desarrollo de un ejemplo práctico.
