Is the long-term mortality similar in COVID-19 and community-acquired pneumonia?

Introduction: There are no data on the association of type of pneumonia and long-term mortality by the type of pneumonia (COVID-19 or community-acquired pneumonia [CAP]) on long-term mortality after an adjustment for potential confounding variables. We aimed to assess the type of pneumonia and risk factors for long-term mortality in patients who were hospitalized in conventional ward and later discharged. Methods: Retrospective analysis of two prospective and multicentre cohorts of hospitalized patients with COVID-19 and CAP. The main outcome under study was 1-year mortality in hospitalized patients in conventional ward and later discharged. We adjusted a Bayesian logistic regression model to assess associations between the type of pneumonia and 1-year mortality controlling for confounders. Results: The study included a total of 1,693 and 2,374 discharged patients in the COVID-19 and CAP cohorts, respectively. Of these, 1,525 (90.1%) and 2,249 (95%) patients underwent analysis. Until 1-year follow-up, 69 (4.5%) and 148 (6.6%) patients from the COVID-19 and CAP cohorts, respectively, died (p = 0.008). However, the Bayesian model showed a low probability of effect (PE) of finding relevant differences in long-term mortality between CAP and COVID-19 (odds ratio 1.127, 95% credibility interval 0.862-1.591; PE = 0.774). Conclusion: COVID-19 and CAP have similar long-term mortality after adjusting for potential confounders.

Eventos cardiovasculares tempranos y tardíos en pacientes ingresados por neumonía adquirida en la comunidad / Early and Late Cardiovascular Events in Patients Hospitalized for Community-Acquired Pneumonia

INTRODUCCIÓN: La neumonía adquirida en la comunidad se asocia al desarrollo de eventos cardiovasculares (ECV). El objetivo del estudio fue analizar los factores relativos al huésped, la gravedad y la etiología que se asocian con la aparición de estos eventos, tempranos y tardíos, y su impacto en la mortalidad. MÉTODO: Estudio prospectivo de cohortes multicéntrico en pacientes ingresados por neumonía. Se recogieron ECV durante el ingreso, a los 30 días (tempranos) y al año (tardíos) y la mortalidad. RESULTADOS: Doscientos dos de 1.967 (10,42%) pacientes presentaron ECV tempranos y 122 (6,64%) tardíos. El 16% de la mortalidad al año se atribuyó a complicaciones cardiovasculares. Los factores del huésped relacionados con complicaciones cardiovasculares fueron: edad ≥ 65 años, abuso de alcohol, tabaquismo y cardiopatía crónica en los tempranos y obesidad, HTA e insuficiencia renal crónica en los tardíos. La presencia de sepsis grave y Pneumonia Severity Index (PSI) ≥ 3 fueron factores de riesgo independiente de eventos tempranos y, únicamente, el PSI ≥ 3 de los tardíos. Streptococcus pneumoniae fue el microorganismo con mayor riesgo de complicaciones cardiovasculares. Desarrollar un ECV fue factor independiente de mortalidad temprana (OR 2,37) y tardía (OR 4,05). CONCLUSIONES: La edad, el tabaquismo, la cardiopatía, la gravedad inicial y el S. pneumoniae son factores de riesgo de presentar ECV tempranos y tardíos, lo que conlleva mayor mortalidad durante y tras el episodio agudo de neumonía. Conocer estos factores puede ser de utilidad para desarrollar estrategias activas de diagnóstico precoz de eventos y/o diseñar ensayos dirigidos a reducir las complicaciones cardiovasculares

INTRODUCTION: Community-acquired pneumonia increases the risk of cardiovascular events (CVE). The objective of this study was to analyze host, severity, and etiology factors associated with the appearance of early and late events and their impact on mortality. METHOD: Prospective multicenter cohort study in patients hospitalized for pneumonia. CVE and mortality rates were collected at admission, 30-day follow-up (early events), and one-year follow-up (late events). RESULTS: In total, 202 of 1,967 (10.42%) patients presented early CVE and 122 (6.64%) late events; 16% of 1-year mortality was attributed to cardiovascular disease. The host risk factors related to cardiovascular complications were: age ≥ 65 years, smoking, and chronic heart disease. Alcohol abuse was a risk factor for early events, whereas obesity, hypertension, and chronic renal failure were related to late events. Severe sepsis and Pneumonia Severity Index (PSI) ≥ 3 were independent risk factors for early events, and only PSI ≥ 3 for late events. Streptococcus pneumoniae was the microorganism associated with most cardiovascular complications. Developing CVE was an independent factor related to early (OR 2.37) and late mortality (OR 4.05). CONCLUSIONS: Age, smoking, chronic heart disease, initial severity, and S. pneumoniae infection are risk factors for early and late events, complications that have been related with an increase of the mortality risk during and after the pneumonia episode. Awareness of these factors can help us make active and early diagnoses of CVE in hospitalized CAP patients and design future interventional studies to reduce cardiovascular risk

Early and Late Cardiovascular Events in Patients Hospitalized for Community-Acquired Pneumonia. / Eventos cardiovasculares tempranos y tardíos en pacientes ingresados por neumonía adquirida en la comunidad.

INTRODUCTION: Community-acquired pneumonia increases the risk of cardiovascular events (CVE). The objective of this study was to analyze host, severity, and etiology factors associated with the appearance of early and late events and their impact on mortality. METHOD: Prospective multicenter cohort study in patients hospitalized for pneumonia. CVE and mortality rates were collected at admission, 30-day follow-up (early events), and one-year follow-up (late events). RESULTS: In total, 202 of 1,967 (10.42%) patients presented early CVE and 122 (6.64%) late events; 16% of 1-year mortality was attributed to cardiovascular disease. The host risk factors related to cardiovascular complications were: age ≥65 years, smoking, and chronic heart disease. Alcohol abuse was a risk factor for early events, whereas obesity, hypertension, and chronic renal failure were related to late events. Severe sepsis and Pneumonia Severity Index (PSI) ≥3 were independent risk factors for early events, and only PSI ≥3 for late events. Streptococcus pneumoniae was the microorganism associated with most cardiovascular complications. Developing CVE was an independent factor related to early (OR 2.37) and late mortality (OR 4.05). CONCLUSIONS: Age, smoking, chronic heart disease, initial severity, and S. pneumoniae infection are risk factors for early and late events, complications that have been related with an increase of the mortality risk during and after the pneumonia episode. Awareness of these factors can help us make active and early diagnoses of CVE in hospitalized CAP patients and design future interventional studies to reduce cardiovascular risk.

In-vivo compatibility between pacemakers and dental equipment.

In-vitro studies suggest that electromagnetic interference can occur under specific conditions involving proximity between electronic dental equipment and pacemakers. At present, in-vivo investigations to verify the effect of using electronic dental equipment in clinical conditions on patients with pacemakers are scarce. This study aimed to evaluate, in vivo, the effect of three commonly used electronic dental instruments - ultrasonic dental scaler, electric pulp tester, and electronic apex locator - on patients with different pacemaker brands and configurations. Sixty-six consecutive non-pacemaker-dependent patients were enrolled during regular electrophysiology follow-up visits. Electronic dental tools were operated while the pacemaker was interrogated, and the intracardiac electrogram and electrocardiogram were recorded. No interferences were detected in the intracardiac electrogram of any patient during the tests with dental equipment. No abnormalities in pacemaker pacing and sensing function were observed, and no differences were found with respect to the variables, pacemaker brands, pacemaker configuration, or mode of application of the dental equipment. Electromagnetic interferences affecting the surface electrocardiogram, but not the intracardiac electrogram, were found in 25 (37.9%) patients, especially while using the ultrasonic dental scaler; the intrinsic function of the pacemakers was not affected. Under real clinical conditions, none of the electronic dental instruments tested interfered with pacemaker function.

Redefining Cut-Points for High Symptom Burden of the Global Initiative for Chronic Obstructive Lung Disease Classification in 18,577 Patients With Chronic Obstructive Pulmonary Disease.

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) can be classified into groups A/C or B/D based on symptom intensity. Different threshold values for symptom questionnaires can result in misclassification and, in turn, different treatment recommendations. The primary aim was to find the best fitting cut-points for Global initiative for chronic Obstructive Lung Disease (GOLD) symptom measures, with an modified Medical Research Council dyspnea grade of 2 or higher as point of reference. METHODS: After a computerized search, data from 41 cohorts and whose authors agreed to provide data were pooled. COPD studies were eligible for analyses if they included, at least age, sex, postbronchodilator spirometry, modified Medical Research Council, and COPD Assessment Test (CAT) total scores. MAIN OUTCOMES: Receiver operating characteristic curves and the Youden index were used to determine the best calibration threshold for CAT, COPD Clinical Questionnaire, and St. Georges Respiratory Questionnaire total scores. Following, GOLD A/B/C/D frequencies were calculated based on current cut-points and the newly derived cut-points. FINDINGS: A total of 18,577 patients with COPD [72.0% male; mean age: 66.3 years (standard deviation 9.6)] were analyzed. Most patients had a moderate or severe degree of airflow limitation (GOLD spirometric grade 1, 10.9%; grade 2, 46.6%; grade 3, 32.4%; and grade 4, 10.3%). The best calibration threshold for CAT total score was 18 points, for COPD Clinical Questionnaire total score 1.9 points, and for St. Georges Respiratory Questionnaire total score 46.0 points. CONCLUSIONS: The application of these new cut-points would reclassify about one-third of the patients with COPD and, thus, would impact on individual disease management. Further validation in prospective studies of these new values are needed.

Distribution and Outcomes of a Phenotype-Based Approach to Guide COPD Management: Results from the CHAIN Cohort.

RATIONALE: The Spanish guideline for COPD (GesEPOC) recommends COPD treatment according to four clinical phenotypes: non-exacerbator phenotype with either chronic bronchitis or emphysema (NE), asthma-COPD overlap syndrome (ACOS), frequent exacerbator phenotype with emphysema (FEE) or frequent exacerbator phenotype with chronic bronchitis (FECB). However, little is known on the distribution and outcomes of the four suggested phenotypes. OBJECTIVE: We aimed to determine the distribution of these COPD phenotypes, and their relation with one-year clinical outcomes. METHODS: We followed a cohort of well-characterized patients with COPD up to one-year. Baseline characteristics, health status (CAT), BODE index, rate of exacerbations and mortality up to one year of follow-up were compared between the four phenotypes. RESULTS: Overall, 831 stable COPD patients were evaluated. They were distributed as NE, 550 (66.2%); ACOS, 125 (15.0%); FEE, 38 (4.6%); and FECB, 99 (11.9%); additionally 19 (2.3%) COPD patients with frequent exacerbations did not fulfill the criteria for neither FEE nor FECB. At baseline, there were significant differences in symptoms, FEV1 and BODE index (all p<0.05). The FECB phenotype had the highest CAT score (17.1±8.2, p<0.05 compared to the other phenotypes). Frequent exacerbator groups (FEE and FECB) were receiving more pharmacological treatment at baseline, and also experienced more exacerbations the year after (all p<0.05) with no differences in one-year mortality. Most of NE (93%) and half of exacerbators were stable after one year. CONCLUSIONS: There is an uneven distribution of COPD phenotypes in stable COPD patients, with significant differences in demographics, patient-centered outcomes and health care resources use.

Factors associated with smoking among tuberculosis patients in Spain.

BACKGROUND: To determine the prevalence of smoking and analyze associated factors in a cohort of patients diagnosed with tuberculosis (TB) in Spain between 2006 and 2013. METHODS: Multicenter, cross-sectional, descriptive, observational study using a national database of TB patients, using logistic regression to calculate odds ratios (OR) and confidence intervals (CI). RESULTS: We analyzed 5,846 cases (62 % men, mean age 39 years, 33 % foreigners). 23.4 % were alcohol abuser, 1.3 % were injected drug users (IDU), 4.6 % were co-infected with HIV, and 7.5 % had a history of TB treatment. 6.6 % and 0.8 % showed resistance to one and multiple drugs, respectively. The predominant clinical presentation was pulmonary (71 %) with a cavitary radiological pattern in 32.8 % of cases. 82 % of cases were confirmed microbiologically, and 54 % were smear-positive microscopy. 2,300 (39.3 %) patients were smokers. The following factors were associated with smoking: male sex (OR = 2.26;CI:1.97;2.60), Spanish origin (OR = 2.79;CI:2.40-3.24), alcoholism (OR = 2.85;CI:2.46;3.31), IDU (OR = 2.78;CI:1.48;5.52), homelessness (OR = 1.99;CI:1.14-3.57), pulmonary TB (OR = 1.61;CI:1.16;2.24), cavitary radiological pattern (OR = 1.99;CI:1.43;2.79) and a smear-positive microscopy at the time of diagnosis (OR = 1.39;CI:1.14;1.17). CONCLUSIONS: The prevalence of smoking among TB patients is high. Smokers with TB have a distinct sociodemographic, clinical, radiological and microbiological profile to non-smokers.

Defining the Asthma-COPD Overlap Syndrome in a COPD Cohort.

BACKGROUND: Asthma-COPD overlap syndrome (ACOS) has been recently described by international guidelines. A stepwise approach to diagnosis using usual features of both diseases is recommended although its clinical application is difficult. METHODS: To identify patients with ACOS, a cohort of well-characterized patients with COPD and up to 1 year of follow-up was analyzed. We evaluated the presence of specific characteristics associated with asthma in this COPD cohort, divided into major criteria (bronchodilator test > 400 mL and 15% and past medical history of asthma) and minor criteria (blood eosinophils > 5%, IgE > 100 IU/mL, or two separate bronchodilator tests > 200 mL and 12%). We defined ACOS by the presence of one major criterion or two minor criteria. Baseline characteristics, health status (COPD Assessment Test [CAT]), BMI, airflow obstruction, dyspnea, and exercise capacity (BODE) index, rate of exacerbations, and mortality up to 1 year of follow-up were compared between patients with and without criteria for ACOS. RESULTS: Of 831 patients with COPD included,125 (15%) fulfilled the criteria for ACOS, and 98.4% of them sustained these criteria after 1 year. Patients with ACOS were predominantly male (81.6%), with symptomatic mild to moderate disease (67%), who were receiving inhaled corticosteroids (63.2%). There were no significant differences in baseline characteristics, and only survival was worse in patients with non-ACOS COPD after 1 year of follow-up (P < .05). CONCLUSIONS: The proposed ACOS criteria are present in 15% of a cohort of patients with COPD and these patients show better 1-year prognosis than clinically similar patients with COPD with no ACOS criteria.

Resistencia a fármacos antituberculosos de primera línea en Españna durante 2010-2011. Estudio RETUBES / Resistance to First-Line Antituberculosis Drugs in Spain, 2010-2011. RETUBES Study

Introducción: La magnitud de la resistencia actual a fármacos antituberculosos en España es desconocida. El objetivo del estudio es describir la resistencia a fármacos antituberculosos de primera línea y determinar sus factores asociados. Métodos: Estudio prospectivo multicéntrico de pacientes tuberculosos adultos con aislamiento de Mycobacterium tuberculosis y antibiograma de fármacos de primera línea en 32 hospitales y un centro extrahospitalario del sistema sanitario nacional durante los años 2010 y 2011. Resultados: Se estudió a 519 pacientes, 342 españoles y 177 (34,1%) extranjeros, 48 de ellos (9,2%) con resistencia a cualquier fármaco, de los que 35 (6,7%) eran resistentes a isoniacida. Hubo 10 casos multirresistentes (1,9%) y ninguno extremadamente resistente. Se detectó resistencia inicial a isoniacida en 28 de los 487 (5,7%) pacientes sin antecedentes de tratamiento antituberculoso previo, afectando más a los extranjeros (p < 0,01), y resistencia adquirida en 7 (22,6%) casos previamente tratados. La multirresistencia fue inicial en 6 casos (1,2%) y adquirida en otros 4 (12,9%). Los factores asociados a tener resistencia inicial a isoniacida fueron ser inmigrante y la convivencia en grupo (OR = 2,3; IC del 95%, 0,98- 5,67, y OR = 2,2; IC del 95%, 1,05-7,07, respectivamente). El factor asociado a la existencia de resistencia adquirida a isoniacida fue la edad inferior a 50 años (p = 0,03). Conclusiones: La tasa de resistencia inicial a isoniacida es superior a la estimada, probablemente debida al aumento de la inmigración durante los últimos años, lo que aconseja su vigilancia nacional sistemática. Los individuos inmigrantes y los que conviven en grupo tienen mayor riesgo de tener resistencia a isoniacida

Introduction: The magnitude of current resistance to antituberculosis drugs in Spain is unknown. The objective of this study is to describe resistance to first-line antituberculosis drugs and determine the associated factors. Methods: Prospective multicenter study of adult tuberculosis patients with positive Mycobacterium tuberculosis culture and antibiogram including first-line drugs in 32 hospitals and one out-patient center of the Spanish Health System between 2010 and 2011. Results: A total of 519 patients, 342 Spanish nationals and 177 (34.1%) foreigners were studied. Drug resistance was found in 48 (9.2%), of which 35 (6.7%) were isoniazid-resistant. There were 10 (1.9%) multiresistant cases and no strain was extremely resistant. Initial isoniazid resistance was detected in 28 of the 487 (5.7%) antituberulosis-naïve patients, most of whom were foreigners (P<.01). Acquired resistance was seen in 7 (22.6%) previously treated cases. Multiresistance was initial in 6 cases (1.2%) and acquired in another 4 (12.9%). Factors associated with initial isoniazid resistance were immigrant status and group cohabitation OR = 2.3; 95%CI: .98-5.67 and OR = 2.2; 95%CI: 1.05-7.07 respectively). The factor associated with acquired resistance to isoniazid was age below 50 years (P=.03). Conclusions: The rate of initial isoniazid resistance is greater than estimated, probably due to the increase in immigration during recent years, suggesting that systematic national monitoring is required. Immigrants and those who cohabit in groups have a higher risk of isoniazid resistance

Efficacy of pulmonary rehabilitation in patients with moderate chronic obstructive pulmonary disease: a randomized controlled trial.

BACKGROUND: Pulmonary Rehabilitation for moderate Chronic Obstructive Pulmonary Disease in primary care could improve patients' quality of life. METHODS: This study aimed to assess the efficacy of a 3-month Pulmonary Rehabilitation (PR) program with a further 9 months of maintenance (RHBM group) compared with both PR for 3 months without further maintenance (RHB group) and usual care in improving the quality of life of patients with moderate COPD.We conducted a parallel-group, randomized clinical trial in Majorca primary health care in which 97 patients with moderate COPD were assigned to the 3 groups. Health outcomes were quality of life, exercise capacity, pulmonary function and exacerbations. RESULTS: We found statistically and clinically significant differences in the three groups at 3 months in the emotion dimension (0.53; 95%CI0.06-1.01) in the usual care group, (0.72; 95%CI0.26-1.18) the RHB group (0.87; 95%CI 0.44-1.30) and the RHBM group as well as in fatigue (0.47; 95%CI 0.17-0.78) in the RHBM group. After 1 year, these differences favored the long-term rehabilitation group in the domains of fatigue (0.56; 95%CI 0.22-0.91), mastery (0.79; 95%CI 0.03-1.55) and emotion (0.75; 95%CI 0.17-1.33). Between-group analysis only showed statistically and clinically significant differences between the RHB group and control group in the dyspnea dimension (0.79 95%CI 0.05-1.52). No differences were found for exacerbations, pulmonary function or exercise capacity. CONCLUSIONS: We found that patients with moderate COPD and low level of impairment did not show meaningful changes in QoL, exercise tolerance, pulmonary function or exacerbation after a one-year, community based rehabilitation program. However, long-term improvements in the emotional, fatigue and mastery dimensions (within intervention groups) were identified. TRIAL REGISTRATION: ISRCTN94514482.

[Efficacy of respiratory rehabilitation on patients with moderate COPD in primary care and maintenance of benefits at 2 years]. / Eficacia de la rehabilitación respiratoria en pacientes con EPOC moderada en atención primaria y mantenimiento de los beneficios a los 2 años.

OBJECTIVES: To assess the efficacy of a pulmonary rehabilitation programme lasting 24 months and carried out at primary care health centres in improving the quality of life of patients with moderate COPD, compared with a programme of 12 weeks pulmonary rehabilitation with the usual care. Secondary aims include the assessment of the effects of the programme on dyspnoea, exercise capacity, reduction of crises, hospital admissions and length of time in hospital. DESIGN: Randomised clinical trial, with 3 groups in parallel and with blind evaluation. The control group will continue with the customary care. SUBJECT: Patients attended at primary health care centres with a diagnosis, based on GOLD criteria, of moderate COPD. Patients will be recruited from 5 health centres. 56 patients per group are needed (allowing for 20% drop-outs) to detect the minimum clinically meaningful differences between treatments, with an alpha error of 0.005 and statistical power of 80%. INTERVENTION: All eligible patients with signed informed consent will be randomised into the following groups: a) pulmonary rehabilitation for 12 weeks and programme maintenance for 24 months; b) pulmonary rehabilitation for 12 weeks without maintenance programme; c) control group continuing with customary care. Pulmonary rehabilitation will include educational sessions, respiratory physiotherapy and low-intensity physical exercise. Follow-ups will be at the end of the rehabilitation programme, and at one and 2 years. MEASUREMENTS: Quality of life with the Chronic Respiratory Questionnaire, 6-minute walking test, Borg Dyspnoea Scale, Medical Research Council Dyspnoea Score, Lung Function Tests, and intervention group.

Manifestaciones orales y periodontales de la enfermedad inflamatoria intestinal / Oral and periodontal manifestations of inflammatory bowel disease

La Enfermedad Inflamatoria Intestinal (Ell) incluye la enfermedad de Crohn y la colitis ulcerosa. Numerosos estudios relacionan dichas afectaciones con la manifestación de determinadas lesiones orales Respecto a la enfermedad periodontal algunos autores la correlacionan con la Ell tanto en su prevalencia como en su grado de actividad. Se ha apuntado la alteración de los PMN como posible factor común en la patogénesis de ambas entidades. El propósito de nuestro artículo es revisar las manifestaciones orales que presentan los pacientes afectos de una Ell, así como dilucidar su implicación con la enfermedad periodontal. Además se repasa el manejo del paciente odontológico con EII sometido a corticoterapia (AU)
