Background: Community-acquired pneumonia (CAP) is a common cause of morbidity and mortality due to misdiagnosis and inappropriate treatment approaches. Objective: To assess the performance of the CORB score in subjects with CAP for predicting in-hospital mortality, death within 30 days of admission, and requirement for invasive mechanical ventilation (IMV) and vasopressor support. Methods: A retrospective, cohort study with diagnostic test analysis of CORB and CURB-65 scores in subjects with CAP according to ATS criteria was undertaken. An alternative CORB score was estimated by replacing SpO2 ≤90% by the SpO2/FiO2 ratio. Crude and adjusted odd ratios (AOR) were calculated for each variable. The area under the receiver operating characteristics curve (AUROC) was constructed for each score, and outcomes were analyzed. AUROCs were compared with the DeLong test, considering a p value <0,05 statistically significant. Results: From 1,811 subjects who entered the analysis, 15.1% (273/1,811) died in hospital, 8.78% required IMV (159/1,811), and 9.77% (177/1,811) needed vasopressor support. CORB had an AUROC of 0,660 (95% CI: 0,623-0,697) for in-hospital mortality; an AUROC of 0,657 (95% CI: 0,621-0,692) for 30-day mortality; an AUROC of 0,637 (CI 95%: 0,589-0,685) for IMV requirement; and an AUROC of 0,635 (95% CI: 0,589-0,681) for vasopressor support. CORB performance increases when the SpO2/FiO2 ratio <300 is used as oxygenation criterion in the prediction of requirement for IMV and vasopressor support, with AUROC of 0,700 (95% CI: 0,654-0,746; p < 0.001) and AUROC of 0,702 (95% CI: 0,66-0,745; p < 0.001), respectively. CURB-65 score presents an in-hospital mortality AUROC of 0,727 (95% CI: 0,695-0,759) and 30-day mortality AUROC of 0,726 (95% CI: 0,695-0,756). Conclusions: CORB score has a good performance in predicting the need for IMV and vasopressor support in CAP patients. This performance improves when the SpO2/FiO2 ratio <300 is used instead of the SpO2 ≤90% as the oxygenation parameter. CURB-65 score is superior in the prediction of mortality.

PURPOSE: The COVID-19 pandemic has spread worldwide, and almost 396 million people have been infected around the globe. Latin American countries have been deeply affected, and there is a lack of data in this regard. This study aims to identify the clinical characteristics, in-hospital outcomes, and factors associated with ICU admission due to COVID-19. Furthermore, to describe the functional status of patients at hospital discharge after the acute episode of COVID-19. MATERIAL AND METHODS: This was a prospective, multicenter, multinational observational cohort study of subjects admitted to 22 hospitals within Latin America. Data were collected prospectively. Descriptive statistics were used to characterize patients, and multivariate regression was carried out to identify factors associated with severe COVID-19. RESULTS: A total of 3008 patients were included in the study. A total of 64.3% of patients had severe COVID-19 and were admitted to the ICU. Patients admitted to the ICU had a higher mean (SD) 4C score (10 [3] vs. 7 [3)], p<0.001). The risk factors independently associated with progression to ICU admission were age, shortness of breath, and obesity. In-hospital mortality was 24.1%, whereas the ICU mortality rate was 35.1%. Most patients had equal self-care ability at discharge 43.8%; however, ICU patients had worse self-care ability at hospital discharge (25.7% [497/1934] vs. 3.7% [40/1074], p<0.001). CONCLUSIONS: This study confirms that patients with SARS CoV-2 in the Latin American population had a lower mortality rate than previously reported. Systemic complications are frequent in patients admitted to the ICU due to COVID-19, as previously described in high-income countries.

Introduction: The walking test of 6 minutes (6MW) is a test that merges the answer of different systems (respiratory, cardiovascular, metabolic, skeletal muscle and neurosensorial) and offers an useful objective result to lead therapeutic measurements and stablish a prognosis, it's possible that the comorbid patient lowers their functional reserve and alters the result of the test not only because of the presence of pathologies cardiorespiratory, nevertheless, information about the correlation between the scores of comorbidity and the traveled distance in the 6MW is limited. Objective: Determine the correlation between the traveled distance in the 6MW and the scores of comorbidities of Charlson and Elixhauser. Methods: A cross-sectional study was made, in patients taken to the 6MW made between 2006 until March 2020, in a hospital of high complexity; there were included patients older than 18 years old, whose clinic history record and walk of 6 minutes were available. The index of Charlson and Elixhauser were calculated in the 6MW, a bivariate analysis was made between the antecedents of pathologies and the traveled distance, independently and adjusted, the spearman correlation coefficient was calculated for the different scores and the distance in meters of the 6MW, was considerate a significative p: <0,05. Results: to the final analysis 491 subjects entered, the average age was of 69 years old (sd: 14,9), 54% male, the 15,3% had an abnormal walk less than the 80% of the expected, the diseases that were considered had a statistically significant relation with the decrease of the distance in the 6MW were arterial hypertension (p: <0,001), chronic heart failure (p=0,037), heart arrhythmia (p=0,003), smoking (p=0,022), chronic pulmonary obstruction disease (p: <0,001), dementia (p=0,03diabetes mellitus with target organ damage (p=0,01), moderate to severe chronic kidney disease (p=0,012), obesity (p=0,036) y lymphoma (p=0,038 the spearman correlation coefficient between the traveled distances and Charlson was of -0,343 (IC95%:-0,420 -0,264)(p: < 0,001) and -0,213(IC95%:-0,285 -0,116)(p: <0,001) with the Elixhauser index. Conclusion: The distances walked in meters in the 6MW has a reverse low correlation with the comorbidity index, the diseases that were not cardiopulmonary and that related independently with changes in the traveled dist ance are smoking, dementia, diabetes mellitus, chronic kidney disease, obesity, and lymphoma.

The association between impairments in swallowing safety detected via fiberoptic endoscopic evaluation of swallowing (FEES) and dysphagia complications has been evaluated in small studies that have not allowed obtaining precise estimates of the presence of such an association. The objective of this study was to evaluate the risk of dysphagia complications associated with the detection of premature spillage, residue, penetration, and aspiration via FEES. A systematic review and meta-analysis of the literature were carried out. A search strategy was established using terms of controlled and free vocabulary (free text) in the PubMed, Lilacs, Embase, Medline, and Cochrane databases. The initial search in the databases identified 3545 articles, of which 321 were excluded due to duplication, 3224 were selected for review of titles and abstracts, 45 were selected for full-text review, 37 were excluded for not meeting the selection criteria, and 8 were included for the final analysis, with a total population of 1168 patients. Aspiration increased the risk of pneumonia (OR 2.97, 95% CI 1.52-5.80, P = 0.001). The number of studies that have evaluated the relationship of other FEES findings with dysphagia complications was limited (≤ 3). One study found a higher risk of mortality in patients with aspiration (OR 4.08, 95% CI 1.60-10.27, P = 0.003). Another study that evaluated the risk of mortality in a combined group of penetration and aspiration found no higher risk of mortality. Penetration, residue, and premature spillage were not found to be associated with an increased risk of pneumonia, mortality, or other outcomes. Aspiration demonstrated via FEES was associated with an increased risk of pneumonia and mortality. There is insufficient evidence for the capacity of premature spillage, penetration, and residue to predict dysphagia complications.

PURPOSE: Dexamethasone is the only drug that has consistently reduced mortality in patients with COVID-19, especially in patients needing oxygen or invasive mechanical ventilation. However, there is a growing concern about the relation of dexamethasone with the unprecedented rates of ICU-acquired respiratory tract infections (ICU-RTI) observed in patients with severe COVID-19. METHODS: This was a multicenter, prospective cohort study; conducted in ten countries in Latin America and Europe. We included patients older than 18 with confirmed SARS-CoV-2 requiring ICU admission. A multivariate logistic regression and propensity score matching (PSM) analysis was conducted to determine the relation between dexamethasone treatment and ICU-RTI. RESULTS: A total of 3777 patients were included. 2065 (54.7%) were treated with dexamethasone within the first 24 h of admission. After performing the PSM, patients treated with dexamethasone showed significantly higher proportions of VAP (282/1652 [17.1%] Vs. 218/1652 [13.2%], p = 0.014). Also, dexamethasone treatment was identified as an adjusted risk factor of ICU-RTI in the multivariate logistic regression model (OR 1.64; 95%CI: 1.37-1.97; p < 0.001). CONCLUSION: Patients treated with dexamethasone for severe COVID-19 had a higher risk of developing ICU-acquired respiratory tract infections after adjusting for days of invasive mechanical ventilation and ICU length of stay, suggesting a cautious use of this treatment.

BACKGROUND: The incidence of invasive pneumococcal disease (IPD) varies depending on a number of factors, including vaccine uptake, in both children and adults, the geographic location, and local serotype prevalence. There are limited data about the burden of Streptococcus pneumoniae (Spn), serotype distribution, and clinical characteristics of adults hospitalized due to IPD in Colombia. The objectives of this study included assessment of Spn serotype distribution, clinical characteristics, mortality, ICU admission, and the need for mechanical ventilation. METHODS: This was an observational, retrospective, a citywide study conducted between 2012 and 2019 in Bogotá, Colombia. We analyzed reported positive cases of IPD from 55 hospitals in a governmental pneumococcal surveillance program. Pneumococcal strains were isolated in each hospital and typified in a centralized laboratory. This is a descriptive study stratified by age and subtypes of IPD obtained through the analysis of medical records. RESULTS: A total of 310 patients with IPD were included, of whom 45.5% were female. The leading cause of IPD was pneumonia (60%, 186/310), followed by meningitis. The most frequent serotypes isolated were 19A (13.87%, 43/310) and 3 (11.94%, 37/310). The overall hospital mortality rate was 30.3% (94/310). Moreover, 52.6% (163/310 patients) were admitted to the ICU, 45.5% (141/310) required invasive mechanical ventilation and 5.1% (16/310) non-invasive mechanical ventilation. CONCLUSION: Pneumococcal pneumonia is the most prevalent cause of IPD, with serotypes 19A and 3 being the leading cause of IPD in Colombian adults. Mortality due to IPD in adults continues to be very high.

ABSTRACT: The National Early Warning Score (NEWS)-2 is an early warning scale that is used in emergency departments to identify patients at risk of clinical deterioration and to help establish rapid and timely management. The objective of this study was to determine the validity and prediction of mortality using the NEWS2 scale for adults in the emergency department of a tertiary clinic in Colombia.A prospective observational study was conducted between August 2018 and June 2019 at the Universidad de La Sabana Clinic.The nursing staff in the triage classified the patients admitted to the emergency room according to Emergency Severity Index and NEWS2. Demographic data, physiological variables, admission diagnosis, mortality outcome, and comorbidities were extracted.Three thousand nine hundred eighty-six patients were included in the study. Ninety-two (2%) patients required intensive care unit management, with a mean NEWS2 score of 7. A total of 158 patients died in hospital, of which 63 were women (40%). Of these 65 patients required intensive care unit management. The receiver operating characteristic curve for NEWS2 had an area of 0.90 (CI 95%: 0.87-0.92). A classification and score equivalency analysis was performed between triage and the NEWS2 scale in terms of mortality. Of the patients classified as triage I, 32.3% died, and those who obtained a NEWS2 score greater than or equal to 10 had a mortality of 38.6%.Among our population, NEWS2 was not inferior in its area under the receiver operating characteristic curve when predicting mortality than triage, and the cutoff point for NEWS2 to predict in-hospital mortality was higher.

OBJECTIVES: Obstructive sleep apnoea (OSA)/hypopnoea syndrome is associated with serious and major multiorgan morbidities, particularly in its most severe forms. However, no severe OSA screening instruments are available for high altitude residents that enable adequate identification and clinical prioritisation of such patients. We aimed at developing a severe OSA prediction tool based on the clinical characteristics and anthropometric measurements of a clinical referral cohort living at 2640 m.a.s.l. DESIGN: Cohort-nested cross-sectional study. SETTING: Sleep laboratory for standard polysomnography (PSG) in Colombia. PARTICIPANTS: A predictive model was generated from 8718 participants referred to the PSG laboratory. Results were subsequently validated in a second cohort of 1898 participants. PRIMARY OUTCOME: To identify clinical and anthropometric variables associated with severe OSA (>30 events/hour) and to include them in a binary logistic regression model. RESULTS: The significant variables that were retained with the presence of severe OSA included Body mass index (BMI), Age, Sex, Arterial hypertension and Neck circumference (BASAN). The area under the receiver operating characteristic curvefor the BASAN index was 0.69 (95% CI: 0.68 to 0.70) in the derivation cohort and 0.67 (95% CI: 0.65 to 0.69) in the validation cohort, whereby a BASAN index ≥2 had a sensitivity of 95% and a specificity of 17% to detect severe OSA. CONCLUSION: An objectively based approach to screen for the presence of severe OSA, the BASAN index, exhibits favourable sensitivity characteristics that should enable its operational use as a screening tool in a Hispanic population with a clinical suspicion of OSA and living at high altitude.

RESUMEN Objetivo: Describir las características clínicas y de laboratorio en pacientes mayores de 15 arios con diagnóstico de lupus eritematoso sistémico (LES) hospitalizados por fiebre, cuyo diagnóstico final fue infección, actividad lúpica o ambas (actividad e infección). Métodos: Se realizó un estudio descriptivo retrospectivo en el que se incluyeron pacientes con diagnóstico de LES admitidos por fiebre en el servicio de urgencias del Hospital Universitario Clínica San Rafael; se estudiaron variables clínicas y paraclínicas, dividiéndose en 3 grupos de interés: pacientes con actividad de la enfermedad, de la infección o de ambas, de acuerdo con el diagnóstico definitivo una vez se daba el alta hospitalaria. Se estudiaron variables clínicas y de laboratorio, realizándose una descripción de la población en los 3 estados. Resultados: Se evaluaron en total 115 pacientes, incluyéndose en el análisis final 108 pacientes. La mediana de edad fue de 36 años y el 86% fueron mujeres. La mediana del puntaje del Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) en toda la población fue de 6 (R 1-15), en los pacientes con infección y actividad el puntaje mostró una mediana de 9,5 (R 6-15). No hubo diferencias significativas entre los síntomas clínicos y los hallazgos de laboratorio en los diferentes grupos. El uso de prednisolona en los últimos 3 meses fue mayor en el grupo de infección (p = 0,001), pero sin diferencias significativas entre las otras terapias de inmunosupresión. Conclusión: El uso de esteroides en los últimos 3 meses, el puntaje de la escala SLEDAI y el tiempo transcurrido desde el diagnóstico de LES podrían ser variables que pueden ayudar a discriminar entre infección y actividad en pacientes con historia de LES y fiebre. Los hallazgos clínicos y paraclínicos no discriminan entre estas condiciones de enfermedad.

ABSTRACT Objective: To describe clinical characteristics and laboratory findings of patients older than 15 years of age diagnosed with Systemic Lupus Erythematosus (SLE) that were admitted to hospital with fever and with a final diagnosis of infection, disease flare-up, or both. Methods: A retrospective chart review of medical charts was performed to identify patients with a diagnosis of SLE with a fever, admitted to the Emergency Department of Hospital Universitario Clinica San Rafael. The data collected included demographics, SLEDAI (Systemic Lupus Erythematosus Disease Activity Index) scores, clinical symptoms, laboratory findings, and steroid use. Results analysis was based on three groups (according to final diagnosis at discharge): patients diagnosed with SLE and infection, SLE and disease flare-up, and SLE with both infection and disease flare-up. Results: This study included 108 patients with a mean age of 36, of whom 86% were female. The mean SLEDAI score of all patients analysed was 6 (R 1-15), and for patients with SLE with both infection and disease flare-up was 9.5 (R 6-15). No significant differences were found with clinical symptoms and laboratory findings for any group analysed. SLE patients diagnosed with infections took significantly more prednisolone in the last three months before admission (P = .001). No differences were found with other immunosuppressants. Conclusion: The use of steroids in the last three months, the SLEDAI score, and time since a SLE diagnosis may be variables used to distinguish between infection and disease flare-up in SLE patients presenting with fever. Clinical symptoms and laboratory results are not useful markers to make this distinction.

BACKGROUND: Invasive pneumococcal disease (IPD) is the leading cause of infectious death worldwide. This study aimed to describe the epidemiology of IPD and the impact of pneumococcal conjugate vaccine-10 (PCV-10) over a 10-year period in Bogotá, Colombia. METHODS: This was a laboratory-based surveillance study of Streptococcus pneumoniae isolated from patients with IPD from 82 hospitals over 10 years in Bogotá, Colombia. Data were compared between two periods: 2007-2011 (before the introduction of PCV-10) and 2012-2017 (after the introduction of PCV-10). RESULTS: In total, 1670 patients with IPD were included in the study between 2007 and 2017. Between 2007 and 2011, the most common serotypes were 14, 1, 6B, 6A and 3. Between 2012 and 2017, the most common serotypes were 19A, 3, 14 and 1. A decrease in the incidence of IPD, particularly in children aged 0-4 years, was noted after the introduction of PCV-10. Importantly, this reduction in incidence was not observed in patients aged ≥50 years. CONCLUSIONS: The IPD burden in Bogotá remained stable between 2007 and 2017. The incidence of IPD decreased in children but not in older adults. The introduction of PCV-10 led to a change in the most prevalent serotypes to serotypes that are not included in PCV-10.

BACKGROUND: Up to 30% of patients admitted to hospitals with invasive pneumococcal disease (IPD) experience major adverse cardiovascular event (MACE) including new/worsening heart failure, new/worsening arrhythmia, and/or myocardial infarction. Streptococcus pneumoniae (Spn) is the most frequently isolated bacterial pathogen among community-acquired pneumonia (CAP) patients and the only etiological agent linked independently to MACE. Nevertheless, no clinical data exist identifying which serotypes of Spn are principally responsible for MACE. METHODS: This was an observational multicenter retrospective study conducted through the Public Health Secretary of Bogotá, Colombia. We included patients with a confirmed clinical diagnosis of IPD with record of pneumococcal serotyping and clinical information between 2012 and 2019. Spn were serotyped using the quellung method by the National Center of Microbiology. MACE were determined by a retrospective chart review. RESULTS: The prevalence of MACE was 23% (71/310) in IPD patients and 28% (53/181) in patients admitted for CAP. The most prevalent S. pneumoniae serotype identified in our study was the 19A, responsible for the 13% (42/310) of IPD in our cohort, of which 21% (9/42) presented MACE. Serotypes independently associated with MACE in IPD patients were serotype 3 (odds ratio [OR] 1, 48; 95% confidence interval [CI] [1.21-2.27]; P = .013) and serotype 9n (OR 1.29; 95% CI [1.08-2.24]; P = .020). Bacteremia occurred in 87% of patients with MACE. Moreover, serum concentrations of C-reactive protein were elevated in patients with MACE versus in non-MACE patients (mean [standard deviation], 138 [145] vs 73 [106], P = .01). CONCLUSIONS: MACE are common during IPD with serotype 3 and 9n independently of frequency.

There is a general lack of published studies on the risk of mortality due to alterations in the safety of swallowing detected during the fiberoptic endoscopic evaluation of swallowing (FEES). We aimed at assessing the risk of mortality of the detection of aspiration, penetration, and pharyngeal residues by FEES. A cohort of consecutively evaluated patients suspected of experiencing oropharyngeal dysphagia undergoing FEES at a tertiary care university hospital were prospectively followed up on to assess mortality. The FEES findings, comorbidities, and potential confounders were studied as predictors of death using a Cox multivariate regression analysis. A total of 148 patients were included, 85 of whom were male (57.4%). The mean age (± standard deviation) was 52.7 years (± 22.1). The median of the follow-up time was 4.5 years. The most frequent conditions were stroke in 50 patients (33.8%), brain and spine traumas in 27 (18.2%), and neurodegenerative diseases in 19 (12.8%). Variables associated with mortality in bivariate analyses were age > 65 years (p < 0.001), pneumonia (p = 0.046), aspiration of any consistency (p < 0.001), and pharyngeal residues (p = 0.017). Variables independently associated with mortality in the Cox multivariate model were age (> 65 years) [adjusted hazard ratio (HR) 5.76; 95% CI 2.72 to 17.19; p = 0.001] and aspiration (adjusted HR: 3.96; 95% CI 1.82 to 14.64; p = 0.003). Aspiration detected by FEES and an age > 65 years are independent predictors of mortality in patients with oropharyngeal dysphagia.

Resumen Antecedentes: los valores de la diferencia alveolo arterial de oxígeno D(A-a)O2 y de la relación presión alveolar de oxígeno y fracción inspirada de oxígeno (PaO2/FiO2), son pobremente conocidos a gran altitud para predecir ventilación mecánica (VM) en pacientes con neumonía adquirida en comunidad (NAC) mayores de 65 años. Objetivo: conocer los valores de D(A-a)O2 y PaO2/FiO2 en pacientes con NAC que requirieron soporte ventilatorio. Métodos: estudio de cohorte prospectivo donde se obtuvo la D(A-a)O2 y PaO2/FiO2 de los gases arteriales de ingreso a urgencias, con cálculo de sensibilidad (S), especificidad (E), valor predictivo positivo (VPP), valor predictivo negativo VPN) y área bajo la curva ROC para el requerimiento de VM en las primeras 72 horas. Resultados: se siguieron 247 pacientes, 37 (15%) requirieron VM, no se encontraron diferencias en edad, género, y comorbilidades entre los grupos de VM y no VM. El área bajo la curva ROC para D(A-a) O2 como predictor de VM fue de 0.84 (IC95%:0.77-0.92), para la PaO2/FiO2 de 0.85 (IC 5%: 0.78-0.92) (p<0.0001). Para una D(A-a)O2 en 55 se obtuvo una sensibilidad para predecir VM en 70.27%, especificidad 86.19%, VPP: 47%, VPN: 94%, razón de verosimilitud positiva (LR+): 5.1, razón de verosimilitud negativa (LR-): 0.3. Una PaO2/FiO2 de 180 tiene una sensibilidad para predecir VM de: 86.65%, especificidad: 70.27%, VPP: 34%, VPN: 97%, LR+: 2.9, LR-: 0.2. La mortalidad global fue 3.2%. Conclusión: los valores de D(A-a)O2 y PaO2/FiO2 se relacionan con el requerimiento de VM en pacientes mayores de 65 años con NAC. (Acta Med Colomb 2016; 41: 169-175).

Abstract Background: the values of the difference of alveolar arterial oxygen D(A-a)O2 and ratio of the alveolar oxygen pressure and fraction of inspired oxygen (PaO2/FiO2) are poorly known at high altitude to predict mechanical ventilation (MV) in patients over 65 years with community-acquired pneumonia (CAP). Objective: to know the values of D(A-a)O2 and PaO2/FiO2 in CAP patients requiring ventilatory support. Methods: prospective cohort study where D(A-a)O2 y PaO2/FiO2 were obtained from arterial blood gases at entrance to the emergency room, with calculation of sensitivity (S), specificity (E), positive predictive value (PPV), negative predictive value (NPP) and area under the ROC curve for MV requirement within the first 72 hours. Results: 247 patients were followed; 37 (15%) required MV. No differences were found in age, gender and comorbidities between the groups of MV and no MV. The area under the ROC curve for D(A-a) O2 as a predictor of MV was 0.84 (95% CI: 0.77 to 0.92), for the la PaO2/FiO2 of 0.85 (95% CI: 0.78 to 0.92) (p <0.0001). For a D(A-a)O2 in 55 patients was obtained a sensibility to predict MV in 70.27%, specificity 86.19%, PPV 47%, NPV 94%, positive likelihood ratio (LR +): 5.1, negative likelihood ratio (LR -): 0.3. A PaO2/FiO2 of 180 has a sensitivity to predict MV of 86.65%, specificity: 70.27%, PPV 34%, NPV 97%, LR +: 2.9, LR: 0.2. Overall mortality was 3.2%. Conclusion: the values of D(A-a)O2 and PaO2/FiO2 relate to the requirement of MV in patients older than 65 with CAP. (Acta Med Colomb 2016; 41: 169-175).

La realización de la prueba de vasorreactividad pulmonar con un vasodilatador arterial inhalado (iloprost), en la evaluación de pacientes con hipertensión arterial pulmonar es recomendación clase IIb, nivel C, según la European Society of Cardiology/European Respiratory Society (ESC/ERS) (1). Su recomendación está dada por la opinión de expertos y pequeños estudios epidemiológicos, siendo este uno de los motivos que debe estimular la realización de estudios que aporten información sobre este tema. El artículo de Sénior JM y cols, es uno de los primeros en nuestro medio que evalúa la utilización de iloprost como un medicamento alternativo para la realización de la prueba de vasorreactividad pulmonar con buenos resultados iniciales (2). La realización de la prueba de vasorreactividad se recomienda para detectar pacientes con hipertensión pulmonar a quienes se les podría administrar como parte de su terapia calcio antagonistas orales, su realización está indicada en hipertensión pulmonar idiopática, hereditaria y asociada con el uso de drogas (anorexígenos) (1, 3). La positividad de la prueba está alrededor de 10% (1, 3), aunque Sénior JM y cols reportan una positividad en su serie de 16.7%, un poco más elevada a la esperada, posiblemente debido a una mayor proporción de mujeres en el estudio y pacientes con clase funcional NYHA II (2). Los criterios de positividad de la prueba fueron adecuadamente evaluados según las guías internacionales .

La tuberculosis latente (TBL) se define como la presencia de una respuesta específica inmune al Mycobacterium tuberculosis en ausencia de enfermedad clínica y radiológica (1), esta condición, al presentarse en personas sin signos o síntomas de tuberculosis no es reportada generalmente y los datos epidemiológicos de prevalencia han sido determinados principalmente por estudios de investigación en poblaciones especiales. De ahí la importancia del artículo de Méndez et al., donde se reporta la prevalencia de TBL en pacientes con diabetes mellitus de 35% (2). La diabetes se ha asociado con un incremento del riesgo de TBL, Hensel et al., en un estudio de prevalencia de 702 adultos refugiados de 54 países reporta una prevalencia de TBL de 43.1% en pacientes con HbA1c ≥ 6.4% y 33.8% en pacientes con HbA1c 5.7%-6.4%, con un OR ajustado según país de procedencia de 2.27 (IC95%: 1.15-4.48) para diabéticos y un OR 1.65 (IC95%: 1.13-2.39) en prediabéticos (3); como lo discutido por Méndez et al., donde se propone que la diabetes podría aumentar el riego de TBL, esta consideración podría tomar relevancia en países en desarrollo que han mejorado el ingreso económico y donde la incidencia de tuberculosis se mantiene, en estos países donde hay un aumento de pacientes con diabetes tipo II, podría existir un aumento a futuro de la incidencia de casos de tuberculosis activa en pacientes con diabetes

INTRODUCTION: Patients with obstructive sleep apnoea hypopnoea syndrome (OSA) might have varying degrees of laryngopharyngeal mechanical hyposensitivity that might impair the brain's capacity to prevent airway collapse during sleep. However, this knowledge about sensory compromises in OSA comes from studies performed using methods with little evidence of their validity. Hence, the purpose of this study is to assess the reliability and accuracy of the measurement of laryngopharyngeal mechanosensitivity in patients with OSA using a recently developed laryngopharyngeal endoscopic esthesiometer and rangefinder (LPEER). METHODS AND ANALYSIS: The study will be prospective and double blinded, with a randomised crossover assignment of raters performing the sensory tests. Subjects will be recruited from patients with suspected OSA referred for baseline polysomnography to a university hospital sleep laboratory. Intra-rater and inter-rater reliability will be evaluated using the Bland-Altman's limits of agreement plot, the intraclass correlation coefficient, and the Pearson or Spearman correlation coefficient, depending on the distribution of the variables. Diagnostic accuracy will be evaluated plotting ROC curves using standard baseline polysomnography as a reference. The sensory threshold values ​​for patients with mild, moderate and severe OSA will be determined and compared using ANOVA or the Kruskal-Wallis test, depending on the distribution of the variables. The LPEER could be a new tool for evaluating and monitoring laryngopharyngeal sensory impairment in patients with OSA. If it is shown to be valid, it could help to increase our understanding of the pathophysiological mechanisms of this condition and potentially help in finding new therapeutic interventions for OSA. ETHICS AND DISSEMINATION: The protocol has been approved by the Institutional Review Board of Fundacion Neumologica Colombiana. The results will be disseminated through conference presentations and peer-reviewed publication. TRIAL REGISTRATION: This trial was registered at Clinical Trials Accuracy of the sensory test using the lLaryngopharyngeal endoscopic esthesiometer in obstructive sleep apnea. Protocol ID: 201611-22405. ID: NCT03109171.

Trichosporon asahii es un hongo patógeno emergente reportado en la literatura médica principalmente en pacientes inmunocomprometidos. No obstante, el presente caso es inusual debido a que se trata de un paciente adulto joven inmunocompetente que presentó fungemia por T. asahii y al mismo tiempo desarrolló insuficiencia respiratoria aguda por bronquiolitis respiratoria y neumonía descamativa, la cual resolvió posterior al tratamiento antimicótico instaurado, soporte ventilatorio y vigilancia en Unidad de Cuidado Intesivo (UCI).

Trichosporon asahii is an emerging fungal pathogen reported in the medical literature mainly in immunologically compromised patients. However, this case is unusual because is a young immunocompetent patient who developed fungemia by T. asahii simultaneously with acute respiratory failure, respiratory bronchiolitis and desquamative interstitial pneumonia, who responded satisfactorily to ventilatory support and antifungal therapy.

Trichosporon asahii é um patógeno fúngico emergente relatado na literatura médica principalmente em pacientes imunologicamente comprometidos. No entanto, este caso é incomum porque é um jovem imunocompetente que desenvolveu fungemia por T. asahii simultaneamente com insuficiência respiratória aguda, bronquiolite respiratória e pneumonia intersticial descamativa, que responderam satisfatoriamente ao suporte ventilatório e à terapia antifúngica.

Introducción: El síndrome de apnea/hipopnea del sueño se ha asociado a alteraciones en el ritmo cardíaco, sin embargo, en nuestro medio hay pocos datos acerca de las características clínicas y los trastornos del ritmo en sujetos con el síndrome llevados a Holter electrocardiográfico. Métodos: Se desarrolló un estudio descriptivo de serie de casos, con toma de datos de historia clínica, en cuanto a edad, género, antecedentes médicos, ecocardiograma, resultados de polisomnografía y diagnóstico de Holter electrocardiográfico en pacientes con síndrome de apnea/hipopnea obstructiva del sueño en un centro de tercer nivel de atención. Resultados: Se analizaron 149 registros, con edad promedio de 63,01 años (DE: 11,76); 101 pacientes (67,8%) presentaron algún tipo de trastorno del ritmo cardíaco y 86 (57,7%) algún tipo de arritmia. El sexo femenino y la enfermedad pulmonar obstructiva crónica se relacionaron con la presencia de arritmia cardíaca (p < 0,05). Conclusión: En este estudio la presencia de arritmias cardiacas en pacientes con síndrome de apnea/hipopnea obstructiva del sueño llevados a Holter electrocardiográfico, fue de 57,7%; en este sentido, el trastorno más frecuente fueron las extrasístoles ventriculares y contribuyeron con un 28,9%. El sexo femenino y la enfermedad pulmonar obstructiva crónica pueden guardar relación con el incremento de trastornos del ritmo cardíaco en los pacientes con síndrome de apnea/hipopnea obstructiva del sueño. Se requieren estudios analíticos para corroborar estos hallazgos.

Introduction: Sleep apnoea-hypopnoea syndrome has been associated to heart rate alterations; however, in our fields there is few data of the clinical characteristics and heart rate disorders in individuals with this syndrome who have been subject to 24-hours ECG Holter monitoring. Methods: This is a case series descriptive study, with data collection of clinical records including age, gender, medical history, echocardiogram, polysomnography results and ECG Holter monitoring diagnosis in patients with obstructive sleep apnoea hypopnoea syndrome at a third level centre. Results: 149 registers were analysed, with an average age of 63.01 (SD: 11.76); 101 patients (67.8%) showed some kind of heart rate disorder and 86 (57.7%) some type of arrhythmia. Being female and suffering from obstructive pulmonary disease were related to the presence of heart arrhythmia (p < 0.05). Conclusion: In this study the presence of heart arrhythmias in patients with obstructive sleep apnoea hypopnoea syndrome subject to 24-hour ECG Holter monitoring was of 57.7%; the most common disorder were ventricular extrasystoles, which accounted for 28.9%. Being female and suffering from obstructive pulmonary disease could be linked with an increase of heart rate disorders in patients with obstructive sleep apnoea hypopnoea syndrome. Analytical studies are required to corroborate the findings.
