[Risk and Mortality Factors for Pleural Effusions Requiring Diagnostic Thoracentesis]. / Factores de riesgo y mortalidad de los derrames pleurales que precisan de una toracocentesis diagnóstica.

Introduction: Occurrence of malignant pleural effusion (PE) is known to be associated with a poor prognosis, but the mortality of patients with non-malignant effusions has not been sufficiently studied. Our objective was to describe the clinical course and explore risk factors associated with all-cause mortality at 1, 5 and 10 years in patients who develop a PE. Methods: Retrospective observational study of patients undergoing diagnostic thoracentesis during the decade 2008-2017 in a pulmonology service. Demographic, biochemical, pathological and evolutionary variables were evaluated. The etiology of the effusions was determined using standardized criteria. Results: Pleural fluid samples from 358 patients with a mean age of 68.9 years (SD 15.1 years), 69.2% males, were analyzed. Malignant (29.4%), parapneumonic (19.8%) and secondary to heart failure (18.9%) effusions predominated. Patients with malignant and heart failure related PE had 1-year mortality rates of 60.0% and 30.8%, respectively, and 85% and 64.7% at 5 years. Male gender (hazard ratio [HR] 1.46; 95% CI: 1.03-2.07), positive cytology for malignancy (HR 1.66; 95% CI: 1.03-2.68) and effusion recurrence (HR 1.61; 95% CI: 1.17-2.21) were associated with a worse prognosis and 5-year mortality. Conclusions: Patients undergoing thoracentesis for effusion have a high short and long-term mortality. In our series of hospitalized patients with PE, the factors associated with higher mortality at 1 and 5 years were age, male sex, recurrence of PE, and coexistence of malignancy.

Gender-Based Analysis of the Psychological Impact of the COVID-19 Pandemic on Healthcare Workers in Spain.

Purpose: This study aims to analyze from a gender perspective the psychological distress experienced by the medical workforce during the peak of the pandemic in Spain. Methods: This is a single-center, observational analytic study. The study population comprised all associated health workers of the Cruces University Hospital, invited by email to participate in the survey. It consisted of a form covering demographic data, the general health questionnaire-28 (GHQ-28), and the perceived stress scale (PSS-14). We used multivariant regression analysis to check the effect of gender on the scores. We used gender analysis in both design and interpretation of data following SAGER guidelines. Results: Females made 74.6% of our sample, but their proportion was higher in lower-paid positions such as nursery (89.9%) than in higher-paid ones. The percentage of women categorized as cases with the GHQ-28 was 78.4%, a proportion significantly higher than in the male population (61.3%, p < 0.001). The multivariant regression analysis showed that being women, working as orderly hospital porters, and having a past psychiatric history were risk factors for higher scores in both the GHQ-28 and PSS-14. Conclusion: Women and those with lower-paid positions were at risk of higher psychological distress and worse quality of life within the medical workforce during the first wave of the pandemic. Gender analysis must be incorporated to analyze this fact better.

Multicentre study: reliability and repeatability of Scheimpflug system measurement in keratoconus.

PURPOSE: To assess the repeatability and reliability of the most important tomographic parameters for characterising keratoconus measured with a Pentacam HR (high resolution). METHODS: Overall, 230 eyes in 158 patients with keratoconus were analysed. We performed five consecutive corneal tomography examinations for each eye with a Pentacam HR in patients with keratoconus. Study eyes were classified into three groups depending on the maximum posterior elevation (max_BFS_post): grade 1 for cases of keratoconus with a max_BFS_post of 40 µm; grade 2 for those with a max_BFS_post of between 41 and 75 µm and grade 3 for those with a max_BFS_post of over 75 µm. We calculated the intraclass correlation coefficients (ICCs) and repeatability limits of parameters from tomography and aberrometry. RESULTS: All the parameters were found to have excellent ICCs (0.9). The repeatability limits for the key parameters were higher than 0.5D for the power parameters, 20° for the axis of corneal astigmatism and 10 µm for the thinnest corneal thickness. Further, we obtained repeatability limits of above 0.1 µm for the aberrometry values and overall greater than 15° for the coma axis. All the values increase with the severity of keratoconus, except for that of the coma axis which falls with keratoconus grade. CONCLUSIONS: The reliability indicated by ICCs supports the view that the Pentacam HR is useful for the diagnosis of keratoconus. The repeatability limits suggest that new criteria should be established for monitoring progression taking into account the real measurements that can be made using this system.

Implementación de NeoKissEs en España: un sistema validado de vigilancia de la sepsis nosocomial en recién nacidos de muy bajo peso / mplementation of NeoKissEs in Spain: A validated surveillance system for nosocomial sepsis in very low birth weight infants

Antecedentes: Las sepsis son las infecciones nosocomiales más frecuentes en las Unidades de Cuidados Intensivos Neonatales (UCIN), afectando especialmente a los recién nacidos de muy bajo peso al nacer (RNMBP, ≤ 1.500 g). Un sistema de vigilancia epidemiológica puede contribuir a su prevención mediante una evaluación continua de su frecuencia y factores de riesgo asociados. El objetivo de este artículo es describir la implementación del sistema de vigilancia de las sepsis nosocomiales en RNMBP (NeoKissEs) en un grupo de UCIN españolas. Métodos: Estudio de cohorte de RNMBP con < 28 días de edad ingresados en las UCIN participantes. Dos UCIN tradujeron y adaptaron materiales a partir del sistema original alemán NEO-KISS. Durante la implementación, se desarrollaron 8talleres formativos, con participación de 210 profesionales. Se creó un sistema web para la introducción de datos de pacientes y episodios de sepsis, su monitorización, análisis comparativo y retroalimentación a las unidades. En cada UCIN, un neonatólogo fue responsable de la implementación, recogiendo información sobre las dificultades percibidas durante el proceso. Resultados: De 50 unidades que aceptaron participar, 45 utilizaron NeoKissEs durante la fase de implementación, registrando 1.108 episodios de sepsis asociados a catéter vascular en 3.638 neonatos, con una tasa de 18,4 episodios por 1.000 pacientes-día con catéter (IC del 95%: 17,8-19,1). Conclusiones: El sistema de vigilancia epidemiológica NeoKissEs representa una fuente útil de información para la comparación estandarizada de la incidencia de sepsis de las UCIN, evaluar factores de riesgo y facilitar la evaluación del efecto de futuras intervenciones preventivas

Background: Bloodstream infections (BSIs) are the most frequent nosocomial infections in neonatal intensive care units (NICUs), especially in very low birth weight (VLBW) infants (birth weight ≤ 1500 g). An epidemiologic surveillance system may contribute to the prevention of infection by continuous monitoring of its frequency and associated risk factors. The aim of this article was to describe the implementation of the NeoKissEs surveillance system for BSIs in VLBW newborns in a group of Spanish NICUs. Methods: We assessed the clinical cohort consisting of all VLBW newborns aged less than 28 days admitted to the participating units. In the pilot phase, 2NICUs translated and adapted materials from the original German NEO-KISS system. During implementation, 210 health care professionals attended one of 8 educational workshops. A web-based system was created that allows entering data regarding patients and BSI episodes, data monitoring, benchmarking and providing feedback to the units. At each NICU, one neonatologist was responsible for the implementation of the system and reporting the difficulties perceived throughout the process. Results: Out of the 50 units that agreed to participate, 45 successfully started using the surveillance platform during the implementation phase, recording 1108 episodes of catheter-associated BSI (CABSI) in 3638 newborns, and finding an overall rate of CABSI of 18.4 (95% CI, 17.8-19.1) per 1000 catheter days. Conclusions: The NeoKissEs surveillance system constitutes a helpful source of information for the purpose of benchmarking the performance of neonatal units, assessing factors associated with BSI in VLBW infants and measuring the impact of future preventive interventions in NICUs

Evaluation of the Reliability and Repeatability of Scheimpflug System Measurement in Keratoconus.

PURPOSE: To assess the reliability and repeatability of the parameters obtained using a Scheimpflug system (Pentacam HR-high resolution) for monitoring progression in eyes with keratoconus. METHODS: A prospective study was conducted based on measurements taken with the Pentacam HR in 82 eyes with keratoconus. We calculated the intraclass correlation coefficient (ICC) and the repeatability limit for topographic and aberrometric parameters. RESULTS: All the parameters analyzed had excellent ICCs, above 0.95 in all cases, except for the measurement of the anterior best-fit sphere, for which the ICC was 0.873. The key repeatability limits for the parameters analyzed were as follows: 1.54 diopters (D) for the maximum keratometry in the central cornea, 1.08 D for maximum keratometry, 32.6 degrees for the axis of corneal astigmatism, 11.9 degrees for the coma axis, and 14.2 µm for thinnest corneal thickness. CONCLUSIONS: The level of repeatability of the measurements obtained with a Pentacam HR confirms the usefulness of this system for the diagnosis of keratoconus. Nevertheless, it has certain limitations for monitoring individual progression of keratoconus and planning intrastromal corneal ring segment insertion.

Aplicación de escalas de carga de trabajo de Enfermería en una unidad de cuidados críticos / Implementation of Nursing workload scales in a critical care unit

OBJETIVOS: determinar la carga de trabajo de Enfermería en una unidad de cuidados críticos cardiacos mediante el uso de la escala NEMS y NAS, valorar el grado de correlación entre ambas escalas y analizar la influencia de características de los pacientes (edad, género y tipo de patología). MÉTODO: se llevó a cabo un estudio observacional, prospectivo, descriptivo y unicéntrico durante el mes de marzo de 2015. Se recogieron 388 registros simultáneos de las escalas NEMS y NAS, así como datos sociodemográficos de los pacientes y el tipo de día (laborable/festivo). Se realizó un análisis descriptivo e inferencial de los datos, para el cual se determinó un nivel de significación de p< 0,05. RESULTADOS: se han obtenido cargas de trabajo estimadas más elevadas con la escala NAS frente a la escala NEMS, siendo dichas cargas significativamente más elevadas para pacientes quirúrgicos en ambos casos. Existe una correlación positiva moderada (r= 0,68) entre las escalas NEMS y NAS. Ambas herramientas estiman como adecuada una ratio enfermera/paciente mayor de la existente (76,9% superior según NAS y 35,3% de acuerdo a la escala NEMS). CONCLUSIONES: la escala NAS estima unas cargas de trabajo de Enfermería más altas y adaptadas a la realidad del trabajo enfermero. La carga de trabajo debe adaptarse a las necesidades específicas de cada unidad, considerando especialmente la proporción de pacientes quirúrgicos
