RESUMO

Improved phenotyping in pneumonia is necessary to strengthen risk assessment. Via a feasible and multidimensional approach with basic parameters, we aimed to evaluate the effect of host response at admission on severity stratification in COVID-19 and community-acquired pneumonia (CAP). Three COVID-19 and one CAP multicenter cohorts including hospitalized patients were recruited. Three easily available variables reflecting different pathophysiologic mechanisms-immune, inflammation, and respiratory-were selected (absolute lymphocyte count [ALC], C-reactive protein [CRP] and, SpO2/FiO2). In-hospital mortality and intensive care unit (ICU) admission were analyzed as outcomes. A multivariable, penalized maximum likelihood logistic regression was performed with ALC (< 724 lymphocytes/mm3), CRP (> 60 mg/L), and, SpO2/FiO2 (< 450). A total of 1452, 1222 and 462 patients were included in the three COVID-19 and 1292 in the CAP cohort for the analysis. Mortality ranged between 4 and 32% (0 to 3 abnormal biomarkers) and 0-9% in SARS-CoV-2 pneumonia and CAP, respectively. In the first COVID-19 cohort, adjusted for age and sex, we observed an increased odds ratio for in-hospital mortality in COVID-19 with elevated biomarkers altered (OR 1.8, 3, and 6.3 with 1, 2, and 3 abnormal biomarkers, respectively). The model had an AUROC of 0.83. Comparable findings were found for ICU admission, with an AUROC of 0.76. These results were confirmed in the other COVID-19 cohorts Similar OR trends were reported in the CAP cohort; however, results were not statistically significant. Assessing the host response via accessible biomarkers is a simple and rapidly applicable approach for pneumonia.

RESUMO

BACKGROUND: It is uncertain whether individualisation of the perioperative open-lung approach (OLA) to ventilation reduces postoperative pulmonary complications in patients undergoing lung resection. We compared a perioperative individualised OLA (iOLA) ventilation strategy with standard lung-protective ventilation in patients undergoing thoracic surgery with one-lung ventilation. METHODS: This multicentre, randomised controlled trial enrolled patients scheduled for open or video-assisted thoracic surgery using one-lung ventilation in 25 participating hospitals in Spain, Italy, Turkey, Egypt, and Ecuador. Eligible adult patients (age ≥18 years) were randomly assigned to receive iOLA or standard lung-protective ventilation. Eligible patients (stratified by centre) were randomly assigned online by local principal investigators, with an allocation ratio of 1:1. Treatment with iOLA included an alveolar recruitment manoeuvre to 40 cm H2O of end-inspiratory pressure followed by individualised positive end-expiratory pressure (PEEP) titrated to best respiratory system compliance, and individualised postoperative respiratory support with high-flow oxygen therapy. Participants allocated to standard lung-protective ventilation received combined intraoperative 4 cm H2O of PEEP and postoperative conventional oxygen therapy. The primary outcome was a composite of severe postoperative pulmonary complications within the first 7 postoperative days, including atelectasis requiring bronchoscopy, severe respiratory failure, contralateral pneumothorax, early extubation failure (rescue with continuous positive airway pressure, non-invasive ventilation, invasive mechanical ventilation, or reintubation), acute respiratory distress syndrome, pulmonary infection, bronchopleural fistula, and pleural empyema. Due to trial setting, data obtained in the operating and postoperative rooms for routine monitoring were not blinded. At 24 h, data were acquired by an investigator blinded to group allocation. All analyses were performed on an intention-to-treat basis. This trial is registered with ClinicalTrials.gov, NCT03182062, and is complete. FINDINGS: Between Sept 11, 2018, and June 14, 2022, we enrolled 1380 patients, of whom 1308 eligible patients (670 [434 male, 233 female, and three with missing data] assigned to iOLA and 638 [395 male, 237 female, and six with missing data] to standard lung-protective ventilation) were included in the final analysis. The proportion of patients with the composite outcome of severe postoperative pulmonary complications within the first 7 postoperative days was lower in the iOLA group compared with the standard lung-protective ventilation group (40 [6%] vs 97 [15%], relative risk 0·39 [95% CI 0·28 to 0·56]), with an absolute risk difference of -9·23 (95% CI -12·55 to -5·92). Recruitment manoeuvre-related adverse events were reported in five patients. INTERPRETATION: Among patients subjected to lung resection under one-lung ventilation, iOLA was associated with a reduced risk of severe postoperative pulmonary complications when compared with conventional lung-protective ventilation.

RESUMO

CONTEXT: There is limited knowledge about the disparities between the sexes in obesity prevalence and associated cardiovascular complications in low- and middle-income countries (LMICs). OBJECTIVE: We undertook a systematic review and meta-analysis to assess sex-specific disparities in the prevalence of obesity and cardiometabolic diseases in LMICs, the burden in women, and variations by region, country's income status, setting, and time. METHODS: We searched major databases from inception to March 2023. Two independent reviewers selected the studies, assessed their quality, and extracted data. We used DerSimonian and Laird random-effects models to obtain pooled estimates of odds ratios and 95% CI for the association between sex and obesity and cardiometabolic diseases, and multilevel random-effects logistic regression models to estimate the prevalence of relevant outcomes (PROSPERO CRD42019132609). RESULTS: We included 345 studies (3 916 276 individuals). The odds of obesity were 2.72-fold higher in women than men (OR 2.72; 95% CI, 2.54-2.91). The sex-specific disparities varied by region, with the greatest disparities in Sub-Saharan Africa (OR 3.91; 95% CI, 3.49-4.39). Among women in LMICs, 23% (95% CI, 21%-25%) had obesity, 27% (95% CI, 24%-29%) had hypertension, and 7% (95% CI, 6%-9%) had type 2 diabetes. The prevalence of obesity and type 2 diabetes in women varied by region, country's income, and setting, with the highest prevalence in the Middle East and North Africa, upper-middle-income countries and urban settings. The odds of hypertension (OR 2.41; 95% CI, 1.89-3.08) and type 2 diabetes (OR 2.65; 95% CI, 1.76-3.98) were doubled in women with vs without obesity. CONCLUSION: There is an urgent need for a women-centred and region-stratified approach to tackle obesity awareness, treatment, and prevention in women in LMICs.

RESUMO

Antecedentes y objetivo: El síndrome aórtico agudo (SAA) es poco frecuente y difícil de diagnosticar, con una gran variabilidad en su cuadro clínico inicial. Los objetivos son: 1) desarrollar un algoritmo informático, o un sistema de apoyo a las decisiones clínicas (SADC), para el manejo y la solicitud de estudios de diagnóstico por imagen en el servicio de Urgencias, en concreto de una tomografía computarizada (TC) de la aorta, ante la sospecha de SAA, 2) determinar el efecto de la implantación de este sistema, y 3) determinar los factores asociados a un diagnóstico radiológico positivo que mejoren la capacidad predictiva de los hallazgos de la TC de aorta. Material y métodos: Tras desarrollar e implementar un algoritmo basado en la evidencia, se estudiaron casos de sospecha de SAA. Se utilizó el test de la χ2 para analizar la asociación entre las variables incluidas en el algoritmo y el diagnóstico radiológico, con 3 categorías: sin hallazgos relevantes, positivo para SAA y diagnósticos alternativos. Resultados: Se identificaron 130 solicitudes; 19 (14,6%) tenían SAA y 34 (26,2%) tenían otra patología aguda. De las 19 con SAA, 15 habían sido estratificadas como de alto riesgo y 4 como de riesgo intermedio. La probabilidad de SAA era 3,4 veces mayor en los pacientes con aneurisma aórtico conocido (p=0,021, IC del 95%: 1,2-9,6) y 5,1 veces mayor en los pacientes con un soplo de insuficiencia vascular aórtica de novo(p=0,019, IC del 95 %: 1,3-20,1). La probabilidad de tener una enfermedad aguda grave alternativa fue 3,2 veces mayor en los pacientes con hipotensión o choque (p=0,02, IC del 95 %: 1,2-8,5). Conclusión: El uso de un SADC en el servicio de Urgencias puede ayudar a optimizar el diagnóstico del SAA. Se demostró que la presencia de un aneurisma aórtico conocido y de insuficiencia valvular aórtica de nueva aparición aumentan significativamente la probabilidad de SAA. Se necesitan más estudios para establecer una regla de predicción clínica.(AU)


Background and objective: Acute aortic syndrome (AAS) is uncommon and difficult to diagnose, with great variability in clinical presentation. To develop a computerized algorithm, or clinical decision support system (CDSS), for managing and requesting imaging in the emergency department, specifically computerized tomography of the aorta (CTA), when there is suspicion of AAS, and to determine the effect of implementing this system. To determine the factors associated with a positive radiological diagnosis that improve the predictive capacity of CTA findings. Materials and methods: After developing and implementing an evidence-based algorithm, we studied suspected cases of AAS. Chi-squared test was used to analyze the association between the variables included in the algorithm and radiological diagnosis, with 3 categories: no relevant findings, positive for AAS, and alternative diagnoses. Results: 130 requests were identified; 19 (14.6%) had AAS and 34 (26.2%) had a different acute pathology. Of the 19 with AAS, 15 had been stratified as high risk and 4 as intermediate risk. The probability of AAS was 3.4 times higher in patients with known aortic aneurysm (P=.021, 95% CI 1.2–9.6) and 5.1 times higher in patients with a new aortic regurgitation murmur (P=.019, 95% CI 1.3–20.1). The probability of having an alternative severe acute pathology was 3.2 times higher in patients with hypotension or shock (P=.02, 95% CI 1.2–8.5). Conclusion: The use of a CDSS in the emergency department can help optimize AAS diagnosis. The presence of a known aortic aneurysm and new-onset aortic regurgitation were shown to significantly increase the probability of AAS. Further studies are needed to establish a clinical prediction rule.(AU)

RESUMO

The 2020-21 West Nile Virus (WNV) outbreak in Andalusia, Spain, was the largest reported in the country, with eight cases of West Nile Neuroinvasive Disease (WNND) diagnosed in a tertiary hospital. Diagnosis of WNND is based on detecting WNV RNA, viral isolation, or demonstrating a specific immune response against the virus, with additional tests used to support the diagnosis. Treatment remains supportive, with variable outcomes. The potential efficacy of plasma exchange (PLEX) in select cases raises the possibility of an autoimmune component secondary to infectious pathology of the central nervous system. The influence of climate change on the expansion of WNV into new regions is a significant concern. It is crucial for physicians practicing in high-risk areas to be knowledgeable about the disease for early prevention and effective control measures.

RESUMO

BACKGROUND: Numerous biomarkers have been proposed for diagnosis, therapeutic, and prognosis in sepsis. Previous evaluations of the value of biomarkers for predicting mortality due to this life-threatening condition fail to address the complexity of this condition and the risk of bias associated with prognostic studies. We evaluate the predictive performance of four of these biomarkers in the prognosis of mortality through a methodologically sound evaluation. METHODS: We conducted a systematic review a systematic review and meta-analysis to determine, in critically ill adults with sepsis, whether procalcitonin (PCT), C-reactive protein (CRP), interleukin-6 (IL-6), and presepsin (sCD14) are independent prognostic factors for mortality. We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials up to March 2023. Only Phase-2 confirmatory prognostic factor studies among critically ill septic adults were included. Random effects meta-analyses pooled the prognostic association estimates. RESULTS: We included 60 studies (15,681 patients) with 99 biomarker assessments. Quality of the statistical analysis and reporting domains using the QUIPS tool showed high risk of bias in > 60% assessments. The biomarker measurement as a continuous variable in models adjusted by key covariates (age and severity score) for predicting mortality at 28-30 days showed a null or near to null association for basal PCT (pooled OR = 0.99, 95% CI = 0.99-1.003), CRP (OR = 1.01, 95% CI = 0.87 to 1.17), and IL-6 (OR = 1.02, 95% CI = 1.01-1.03) and sCD14 (pooled HR = 1.003, 95% CI = 1.000 to 1.006). Additional meta-analyses accounting for other prognostic covariates had similarly null findings. CONCLUSION: Baseline, isolated measurement of PCT, CRP, IL-6, and sCD14 has not been shown to help predict mortality in critically ill patients with sepsis. The role of these biomarkers should be evaluated in new studies where the patient selection would be standardized and the measurement of biomarker results.

RESUMO

Cross-table ventilation during tracheal resection via posterolateral thoracotomy presents a technical challenge. With the ubiquity of venovenous extracorporeal membrane oxygenation (VV-ECMO), there is now a safe and feasible alternative for intraoperative respiratory support. Airway surgery on ECMO avoids prolonged periods of apnea or single lung ventilation, allowing patients with poor lung function to undergo surgery. Image-guided femoro-femoral cannulation using a low-dose heparin protocol minimizes the risk of bleeding while uncluttering the surgical field. By eliminating the need to constantly reposition the endotracheal tube, visualization is improved, and the rhythm of the case is maintained, which can shorten the anastomotic time. Here, we present a case where venovenous ECMO and total intravenous anesthesia were used to completely support a patient undergoing major tracheal surgery without the need for cross-table ventilation.

RESUMO

Introduction: Mitral Regurgitation (MR) has a strong impact on quality of life and on mid-term survival. Transcatheter mitral valve replacement (TMVR) is rapidly expanding and a growing number of studies have been published recently. Methods: A systematic review of studies reporting on clinical data for patients with symptomatic severe MR undergoing TMVR was performed. Early- and mid-term outcomes (clinical and echocardiographic) were evaluated. Overall weighted means and rates were calculated. Risk ratios or mean differences were calculated for pre- and post-procedural comparisons. Results: A total of 12 studies and 347 patients who underwent TMVR with devices clinically available or under clinical evaluation were included. Thirty-day mortality, stroke and major bleeding rates were 8.4%, 2.6%, and 15.6%, respectively. Pooled random-effects demonstrated a significant reduction of ≥ grade 3+ MR (RR: 0.05; 95% CI: 0.02-0.11; p < 0.001) and in the rates of patients in NYHA class 3-4 after the intervention (RR: 0.27; 95% CI: 0.22-0.34; p < 0.001). Additionally, the pooled fixed-effect mean difference for quality of life based on the KCCQ score yielded an improvement in 12.9 points (95% CI:7.4-18.4, p < 0.001), and exercise capacity improved by a pooled fixed-effect mean difference of 56.8 meters in the 6-minute walk test (95% CI 32.2-81.3, p < 0.001). Conclusions: Among 12 studies and 347 patients comprising the updated evidence with current TMVR systems there was a statistically significant reduction in ≥ grade 3+ MR and in the number of patients exhibiting poor functional class (NYHA 3 or 4) after the intervention. Overall rate of major bleeding was the main shortcoming of this technique.

RESUMO

Introducción y objetivos La insuficiencia tricuspídea (IT) se asocia con un peor pronóstico si no se corrige. Se han publicado recientemente numerosos estudios sobre reparación transcatéter de la válvula tricúspide (RTT) Métodos Se llevó a cabo una revisión sistemática de estudios que publican datos clínicos de pacientes con IT significativa sometidos a RTT. Se evaluaron objetivos clínicos y ecocardiográficos a corto y medio plazo. Las razones de riesgo (RR) y las diferencias de medias (DM) se obtuvieron de la comparación de datos previos y posteriores a la intervención. Se hizo también un análisis de sensibilidad según el abordaje principal (reparación borde a borde frente a anuloplastia) Resultados Se incluyeron 19 estudios (todos observacionales o ensayos de un solo grupo) con un total de 991 pacientes sometidos a RTT sola. Las tasas de mortalidad e ictus a 30 días fueron del 2,8 y el 0,2% respectivamente. El análisis agrupado de efectos aleatorios mostró una reducción significativa de IT (RR=0,33; IC95%, 0,26-0,42; p <0,001), vena contracta (DM, 5,9mm; IC95%, 4-7,9; p <0,001), diámetro telediastólico del ventrículo derecho (DM, 3,5mm; IC95%, 2,5-4,5; p <0,001) y clase funcional de la NYHA 3 o 4 (RR=0,32; IC95%, 0,27-0,37; p <0,001) a los 30 días. Las complicaciones hemorrágicas y la IT residual al menos grave fueron numéricamente superiores en el grupo de anuloplastia percutánea en comparación con el grupo de reparación borde a borde (hemorragias, el 13,3 y el 2,8%; IT residual, el 40,4 y el 27,9%) Conclusiones En los 991 pacientes que formaron parte de la experiencia inicial de RTT, tras la intervención se observó una reducción estadísticamente significativa del grado de IT grave o peor, una mala clase funcional (NYHA 3-4), la anchura de la vena contracta y el diámetro telediastólico del ventrículo derecho. Hasta ahora, el abordaje con reparación borde a borde parece tener un mejor perfil de seguridad (AU)


Introduction and objectives Severe tricuspid regurgitation (TR) is associated with poor prognosis when left untreated, and a growing number of studies on transcatheter tricuspid valve repair (TTVr) have been published over the last few months. Methods We performed a comprehensive systematic review of published literature providing clinical data on TTVr for patients with significant TR. Early and mid-term clinical and echocardiographic outcomes were evaluated. Risk ratios (RR) or mean differences (MD) were obtained when comparing pre- and postprocedural data. A sensitivity analysis was also performed according to the main approach for repair (edge-to-edge vs annuloplasty). Results A total of 19 studies (all observational or single-arm trials) and 991 patients who underwent isolated TTVr were included. Thirty-day mortality and stroke rates were 2.8% and 0.2%, respectively. Pooled random-effects resulted in a significant reduction of ≥ severe TR (RR, 0.33; 95%CI, 0.26-0.42; P<.001), vena contracta width (MD, 5.9mm; 95%CI, 4-7.9; P <.001), right ventricular end-diastolic diameter (MD, 3.5mm; 95%CI, 2.5-4.5; P <.001), and New York Heart Association (NYHA) class III or IV at last follow-up (RR, 0.32; 95%CI, 0.27-0.37; P <.001). Bleeding complications and residual ≥ severe TR were numerically higher in the annuloplasty-like group compared with edge-to-edge repair (13.3% vs 3.8% for bleeding and 40.4% vs 27.9% for residual severe TR). Conclusions Among 991 patients comprising the early experience for several TTVr devices, there was a statistically significant reduction in ≥ severe TR, NYHA class III-IV, vena contracta width and right ventricular end-diastolic diameter after TTVr. Thus far, the edge-to-edge approach seems to be associated with a better safety profile (AU)

RESUMO

We assessed whether low CD4 count and high viral load (VL) affect the response to currently preferred ART. We performed a systematic review of randomized, controlled clinical trials that analyzed preferred first-line ART and a subgroup analysis by CD4 count (≤ or >200 CD4/µL) or VL (≤ or >100 000 copies/mL). We computed the odds ratio (OR) of treatment failure (TF) for each subgroup and individual treatment arm. Patients with ≤200 CD4 cells or VL ≥100 000 copies/mL showed an increased likelihood of TF at 48 weeks: OR, 1.94; 95% confidence interval (CI): 1.45-2.61 and OR, 1.75; 95% CI: 1.30-2.35, respectively. A similar increase in the risk of TF was observed at 96 weeks. There was no significant heterogeneity regarding integrase strand transfer inhibitor or nucleoside reverse transcriptase inhibitor backbone. Our results show that CD4 <200 cells/µL and VL ≥100,000 copies/mL impair ART efficacy in all preferred regimens.

RESUMO

BACKGROUND: Systematic reviews of studies of clinical prediction models are becoming increasingly abundant in the literature. Data extraction and risk of bias assessment are critical steps in any systematic review. CHARMS and PROBAST are the standard tools used for these steps in these reviews of clinical prediction models. RESULTS: We developed an Excel template for data extraction and risk of bias assessment of clinical prediction models including both recommended tools. The template makes it easier for reviewers to extract data, to assess the risk of bias and applicability, and to produce results tables and figures ready for publication. CONCLUSION: We hope this template will simplify and standardize the process of conducting a systematic review of prediction models, and promote a better and more comprehensive reporting of these systematic reviews.

RESUMO

BACKGROUND: The use of mitral transcatheter edge-to-edge repair (TEER) is rapidly increasing. Anatomical changes have been described after TEER with the MitraClip system in patients with functional mitral regurgitation (MR), although no study has yet evaluated such anatomical impacts in patients treated with the G4 MitraClip generation. METHODS: This research constituted a prospective, single-center, observational study including consecutive patients with functional MR. Mitral three-dimensional images were obtained transesophageally with echocardiography before and immediately after TEER. Patients receiving the late-generation (G4) system were compared to those receiving early-generation systems. RESULTS: A total of 116 functional MR patients were evaluated, and 40 (34.5%) and 76 (65.5%) received a late-generation (G4) or early-generation device system, respectively. The baseline clinical and echocardiographic features were well-balanced between the groups. Overall, there was a significant reduction in mitral annular size after the intervention, and greater reductions in the anteroposterior diameter (4 mm vs. 3.54 mm, p = 0.03), annular perimeter (11.07 mm vs. 5.29 mm for 3D-perimeter, p = 0.001), and annular area (1.29 cm2 vs. 1.03 cm2, p = 0.002) were found for patients receiving the late G4 device generation compared to the early-generation systems. CONCLUSIONS: In patients with functional MR, we observed significant changes in mitral valve anatomy with a reduction in anteroposterior diameter, valve perimeter, and area. In our cohort, the extent of those changes was greater with the use of the new-generation G4 MitraClip system compared to prior device generations.

RESUMO

BACKGROUND: Patient-reported outcomes (PROs) assessment is a necessary component of surgical outcome assessment and patient care. This study examined the success of routine PROs assessment in an academic-based thoracic surgery practice. METHODS: PROs, measuring pain intensity, physical function, and dyspnea, were routinely obtained using the National Institutes of Health-sponsored Patient-Reported Outcomes Measurement Information System (PROMIS) on all thoracic surgery patients beginning in April 2018 through January 2021. Questionnaires were administered electronically through a web-based platform at home or during the office visit. Completion rates and barriers were measured. RESULTS: A total of 9725 thoracic surgery office visits occurred during this time frame. PROs data were obtained in 6899 visits from a total of 3551 patients. The mean number of questions answered per survey was 22.4 ± 2.2. Overall questionnaire completion rate was 65.7%. A significant decline in survey completion was noted in April 2020, after which adjustments were made to allow for questionnaire completion through a mobile health platform. Overall monthly questionnaire completion rates ranged from 20% (April 2020) to 90% (October 2018). Mean T scores were dyspnea, 41.6 ± 12.3; physical function, 42.7 ± 10.5; and pain intensity, 52.8 ± 10.3. CONCLUSIONS: PROs can be assessed effectively in a thoracic surgery clinic setting, with minimal disruption of clinical activities. Future efforts should focus on facilitating PROs collection from disadvantaged patient populations and scaling implementation across programs.

RESUMO

INTRODUCTION AND OBJECTIVES: Severe tricuspid regurgitation (TR) is associated with poor prognosis when left untreated, and a growing number of studies on transcatheter tricuspid valve repair (TTVr) have been published over the last few months. METHODS: We performed a comprehensive systematic review of published literature providing clinical data on TTVr for patients with significant TR. Early and mid-term clinical and echocardiographic outcomes were evaluated. Risk ratios (RR) or mean differences (MD) were obtained when comparing pre- and postprocedural data. A sensitivity analysis was also performed according to the main approach for repair (edge-to-edge vs annuloplasty). RESULTS: A total of 19 studies (all observational or single-arm trials) and 991 patients who underwent isolated TTVr were included. Thirty-day mortality and stroke rates were 2.8% and 0.2%, respectively. Pooled random-effects resulted in a significant reduction of ≥ severe TR (RR, 0.33; 95%CI, 0.26-0.42; P < .001), vena contracta width (MD, 5.9mm; 95%CI, 4-7.9; P <.001), right ventricular end-diastolic diameter (MD, 3.5mm; 95%CI, 2.5-4.5; P <.001), and New York Heart Association (NYHA) class III or IV at last follow-up (RR, 0.32; 95%CI, 0.27-0.37; P <.001). Bleeding complications and residual ≥ severe TR were numerically higher in the annuloplasty-like group compared with edge-to-edge repair (13.3% vs 3.8% for bleeding and 40.4% vs 27.9% for residual severe TR). CONCLUSIONS: Among 991 patients comprising the early experience for several TTVr devices, there was a statistically significant reduction in ≥ severe TR, NYHA class III-IV, vena contracta width and right ventricular end-diastolic diameter after TTVr. Thus far, the edge-to-edge approach seems to be associated with a better safety profile.
