Síntomas de Burnout entre médicos y enfermeros antes, durante y después de atender pacientes con COVID-19 / Burnout symptoms among physicians and nurses before, during and after COVID-19 care / Sintomas de burnout entre médicos e enfermeiros antes, durante e depois do cuidado de pacientes com COVID-19

Objetivo: este estudio evaluó síntomas de Burnout entre médicos y enfermeros antes, durante y después de la atención provista a pacientes con la enfermedad COVID-19. Método: estudio comparativo y transversal realizado en la unidad de Atención Respiratoria de un hospital público de nivel terciario. Se empleó el Inventario de Burnout Maslach. Resultados: se distribuyeron 280 encuestas entre los tres períodos: antes (n=80), durante (n=105) y después (n=95) de la atención a pacientes con COVID-19; se obtuvieron 172 encuestas respondidas. Las tasas de respuesta fueron 57,5%, 64,8% y 61,1%, respectivamente. Los valores de prevalencia de Burnout grave fueron 30,4%, 63,2% y 34,5% antes, durante y después de la atención a pacientes por la enfermedad del coronavirus 2019 (p<0,001). Los síntomas de agotamiento emocional (p<0,001) y despersonalización (p=0,002) fueron más prevalentes entre los enfermeros que entre los médicos. El Síndrome de Burnout grave fue más prevalente en las mujeres, los enfermeros y el personal del turno noche. Conclusión: la elevada prevalencia de Burnout se duplicó en el primer pico de internaciones y regresó a niveles previos a la pandemia un mes después de finalizada la atención a pacientes por la enfermedad del coronavirus 2019. El Síndrome de Burnout varió por sexo, turno de trabajo y ocupación, y los enfermeros representaron los grupos más vulnerables. Es necesario enfocarse en estrategias de evaluación y mitigación tempranas para asistir a los enfermeros, no solo durante la crisis sino permanentemente.

Objective: this study evaluated burnout symptoms among physicians and nurses before, during and after COVID-19 care. Method: a cross-sectional comparative study in the Pulmonary Care unit of a tertiary-level public hospital. The Maslach Burnout Inventory was used. Results: 280 surveys were distributed across three periods: before (n=80), during (n=105) and after (n=95) COVID-19 care; 172 surveys were returned. The response rates were 57.5%, 64.8% and 61.1%, respectively. The prevalence of severe burnout was 30.4%, 63.2% and 34.5% before, during and after COVID-19 care (p<0.001). Emotional exhaustion (p<0.001) and depersonalization (p=0.002) symptoms were more prevalent among nurses than among physicians. Severe burnout was more prevalent in women, nurses and night shift staff. Conclusion: the high prevalence of burnout doubled in the first peak of hospital admissions and returned to pre-pandemic levels one month after COVID-19 care ended. Burnout varied by gender, shift and occupation, with nurses among the most vulnerable groups. Focus on early assessment and mitigation strategies are required to support nurses not only during crisis but permanently.

The Prevalence of Depression and Anxiety Symptoms and Their Association With Respiratory Diseases.

INTRODUCTION: Patients with respiratory diseases face adverse situations such as symptom management, general condition deterioration, and a hostile perception of the hospital environment, favoring the appearance of anxiety and depression. METHODS: A total of 317 patients hospitalized for a disease of pulmonary origin were analyzed and divided into the following subgroups: infectious, oncological, acute, and chronic diseases. Patients over 18 years of age with preserved cognitive capacity were included in the study. The Hospital Anxiety and Depression Scale (HADS) was applied to them on the second or fourth day of their hospital stay and five days after the first evaluation. Multiple linear regression models were carried out to analyze the association between anxiety and depression measured over two different periods. The models present the statistically significant variables with a 95% confidence level. RESULTS: The patients presented with anxiety in 74.4% of cases, mainly those with acute respiratory diseases (42.4%) and neoplastic diseases (27.5%). A total of 69.5% presented with depression, with symptoms more significant in those with chronic and oncological pulmonary diseases and those with no job. Patients with at least one comorbidity presented with anxiety in 53.9% of cases and depression in 52.1% of cases. Linear regression models were carried out and showed that anxiety was 1.75 and 1.84 times more frequent in patients with chronic diseases compared to those with infectious pathologies in the first and second reviews, respectively. The linear regression model also showed a higher frequency of depressive symptoms in patients with chronic conditions (1.62 times) compared to the group with infectious and contagious pathologies, and prolonged hospital stays were associated with depressive symptoms 1.37 times more than short stays. CONCLUSIONS: Anxiety and depression are frequent disorders in patients with respiratory diseases, negatively affecting the prognosis. Routine mental health screening and multidisciplinary management are essential in this population.

Utility of a clinical risk scale to predict the requirement of advanced airway management in patients with a diagnosis of deep neck abscess.

OBJECTIVES: To analyze the clinical utility of a clinical risk scale to predict the need for advanced airway management in patients with deep neck abscess. METHODS: Observational, analytical, cross-sectional study. Patients over 18 years old, both genders, with surgical management of a deep neck abscess, between January 1st, 2015 to December 31th, 2021, who were applied the clinical risk scale (https://7-414-5-19.shinyapps.io/ClinicalRiskScore/). The sensitivity, specificity, and predictive values of the scale were calculated based on the identified clinical outcomes. A p<0.05 was considered significant. RESULTS: A sample of 213 patients was obtained, 121 (56.8%) men, of whom 50 (23.5%) required advanced airway management. Dyspnea was the variable with the most statistical weight in our study, (p=0.001) as well as the multiple spaces involvement, (p=0.001) the presence of air corpuscles, (p=0.001) compromise of the retropharyngeal space (p=0.001) and age greater than 55 years (p=0.001). Taking these data into account, were found for the clinical risk scale a sensitivity of 97% and a specificity of 65% (p=0.001, 95% CI 0.856-0.984). CONCLUSIONS: The clinical risk scale developed to predict advanced airway management in patients with a diagnosis of deep neck abscess may be applicable in our environment with high sensitivity and specificity. LEVEL OF EVIDENCE: IV.

Tuberculosis extrapulmonar: un problema de salud pública.

Extrapulmonary tuberculosis is defined as that case of tuberculosis clinically diagnosed and confirmed by bacteriological studies that affects tissues and organs outside the lung parenchyma. Mexico is in third place among Latin American countries in terms of the incidence of pulmonary and extrapulmonary tuberculosis. Culture methods are still the gold standard for the diagnosis of extrapulmonary tuberculosis since they identify the species and susceptibility to drugs.

La tuberculosis extrapulmonar es aquella tuberculosis diagnosticada clínicamente y confirmada por estudios bacteriológicos que afecta a tejidos y órganos fuera del parénquima pulmonar. México es el tercer lugar en América Latina en incidencia de tuberculosis pulmonar y extrapulmonar. Los métodos de cultivo siguen siendo el método de referencia para el diagnóstico de tuberculosis extrapulmonar, ya que identifican la especie y la sensibilidad a los fármacos.

Asociación del signo de Moore con la presencia de absceso profundo de cuello de espacio retrofaríngeo.

BACKGROUND: Deep neck abscesses can cause life-threatening complications. They are diagnosed by physical examination, and contrasted tomography as the gold standard. There are no studies about the association of Moore's sign with infections of the retropharyngeal space. OBJECTIVE: To determine the usefulness of Moore's sign in the diagnosis of deep retropharyngeal abscess. METHOD: Observational, analytical, cross-sectional, study of patients with deep neck abscess, from May 1, 2019, to August 30, 2021, with report of Moore's sign. RESULTS: 87 patients were included, 49 (56.3%) males (p = 0.45). Of those who developed complications, 77.8% had a negative Moore's sign (p = 0.001). Of those admitted to the ICU, 72% had a negative Moore's sign (p = 0.001). The sensitivity of the absence of the sign with retropharyngeal involvement was 95.4%, and the specificity was 86.3%. By logistic regression, it was found that those with retropharyngeal involvement are 467 times more likely to present a negative sign (p < 0.05). CONCLUSIONS: The presence of abscess in the retropharynx is associated with complications and a worse prognosis. The evaluation of Moore's sign can be a useful tool to suspect compromise of this space.

ANTECEDENTES: Los abscesos profundos de cuello pueden ocasionar complicaciones letales. Se diagnostican por exploración física, y la tomografía contrastada es el método de referencia. No existen estudios de asociación del signo de Moore con infecciones del espacio retrofaríngeo. OBJETIVO: Determinar la utilidad del signo de Moore en el diagnóstico de absceso profundo en el espacio retrofaríngeo. MÉTODO: Estudio observacional, transversal y analítico, de pacientes con absceso profundo de cuello, del 1 de mayo de 2019 al 30 de agosto de 2021, con reporte de signo de Moore. RESULTADOS: Se incluyeron 87 pacientes, de los cuales 49 (56.3%) eran de sexo masculino (p = 0.45). De los que desarrollaron complicaciones, el 77.8%, tenían el signo de Moore negativo (p = 0.001). De los que ingresaron a la unidad de cuidados intensivos, el 72% tenían negativo el signo de Moore (p = 0.001). La sensibilidad de la ausencia del signo con afección del espacio retrofaríngeo fue del 95.4%, y la especificidad del 86.3%. Por regresión logística se encontró que aquellos con afección del espacio retrofaríngeo tienen 467 veces más posibilidades de presentar signo negativo (p < 0.05). CONCLUSIONES: La presencia de un absceso en el espacio retrofaríngeo se asocia a complicaciones y peor pronóstico. La evaluación del signo de Moore puede ser una herramienta útil para sospechar compromiso de ese espacio.

A randomized, double-blind, placebo-controlled 12-week trial of infliximab in patients with juvenile-onset spondyloarthritis.

OBJECTIVE: To assess the efficacy and safety of infliximab versus placebo in the treatment of patients with juvenile-onset spondyloarthritis (JoSpA). METHODS: Phase III, randomized, double-blind, placebo-controlled trial of 12 weeks that included patients ≤ 18 years old with JoSpA not responding to nonsteroidal anti-inflammatory drugs, sulfasalazine, or methotrexate. Patients were randomly assigned 1:1 to the infusion of infliximab 5mg/kg or placebo; completers entered then an open-label extension (OLE) period of 42 weeks. The primary endpoint was the number of active joints. Secondary outcomes included the assessment of disease activity, tender entheses, spinal mobility, serum C-reactive protein (CRP), the Bath Ankylosing Spondylitis Disease Activity and Functional Index, and the Childhood Health Assessment Questionnaire (CHAQ). RESULTS: We randomized 12 patients to infliximab and 14 to placebo. No significant differences were found between groups at baseline. At week 12, the mean number of active joints was 1.4 (SD 2.4) in the infliximab group and 4.1 (SD 3.0) in the placebo group (p = 0.0002). A repeated-measures mixed model analysis that included all endpoints in the study demonstrated sustained favourable outcomes of infliximab for active joints, tender joints, swollen joints, and tender enthesis counts, as well as for CHAQ and CRP (p < 0.01). Adverse events were more frequent in the infliximab group, including infections and infusion reactions, but none of them was serious. CONCLUSION: Infliximab is efficacious for patients with JoSpA with an inadequate response to conventional treatment. No serious adverse events with the use of infliximab were observed.

Gastric variceal bleeding treated through endoscopic ultrasound-guided coiling and N-butyl-2-cyanoacrylate application.

OBJECTIVE: To evaluate efficacy and safety between dual angiotherapy (endocoil plus N-butyl-cyanoacrylate) guided by endoscopic ultrasound) versus N-butyl-cyanoacrylate in the secondary prophylaxis of gastroesophageal varices (GOV). METHOD: Prospective non-inferiority study comparing two gastric variceal eradication techniques. We evaluated technical and clinical success, GOV occlusion and eradication, rebleeding, reoperation, GOV-free period, complications, and mortality. Chi square for categorical variables and Student's t for numerical variables with a significance level of 0.05. RESULTS: There were 68 patients (average age 55.5 ± 10 years, women 44 (64.7%) and average body mass index 25.7 ± 3.5 kg/m2). The most frequent cause was alcoholic steatohepatitis (58%). Dual therapy had greater technical (100% vs. 94.3%) and clinical (100% vs. 85%) success. Obliteration was faster (100 vs. 79.2%). This group only required one session. The GOV size was 24 ± 14 mm and 1-2 endocoils were placed. The median follow-up was 221 days. The reoperation-free rate was high (100% vs. 94%; p = 0.9). CONCLUSIONS: Dual angiotherapy guided by endoscopic ultrasound and cyanoacrylate injection are effective for the eradication of GOV without differences in adverse event rates.

OBJETIVO: Evaluar la eficacia y la seguridad de la angioterapia dual (endo-coil más N-butil-cianoacrilato) guiada por ultrasonido endoscópico) frente a N-butil-cianoacrilato solo en la profilaxis secundaria de várices gásctricas. MÉTODO: Estudio prospectivo de no inferioridad comparando dos técnicas de erradicación de várices gástricas. Se evalúan el éxito técnico y clínico, la oclusión y la erradicación de GOV, el resangrado, la reintervención, el período libre de GOV, las complicaciones y la mortalidad. Análisis estadístico mediante prueba de χ2 para variables categóricas y t de Student para las numéricas, con nivel de significancia de 0.05. RESULTADOS: Fueron 68 pacientes (edad promedio 55.5 ± 10 años, mujeres 44 (64.7%) e índice de masa corporal promedio 25.7 ± 3.5 kg/m2). La causa más frecuente fue esteatohepatitis alcohólica (58%). La terapia dual tuvo mayor éxito técnico (100% vs. 94.3%) y clínico (100% vs. 85%), y la obliteración fue más rápida (100 vs. 79.2%); este grupo solo requirió una sesión. El tamaño de las GOV fue de 24 ± 14 mm y se colocaron uno o dos endo-coils. La mediana de seguimiento fue de 221 días. La tasa de libres de reintervención fue alta (100% vs. 94%; p = 0.9). CONCLUSIONES: La angioterapia dual guiada por ultrasonido y la inyección de cianoacrilato son efectivas para la erradicación de las GOV, sin diferencias en las tasas de eventos adversos.

Usefulness of optical enhancement endoscopy combined with magnification to improve detection of intestinal metaplasia in the stomach.

Background and study aims The light blue crest observed in narrow band imaging endoscopy has high diagnostic accuracy for diagnosis of gastric intestinal metaplasia (GIM). The objective of this prospective study was to evaluate the diagnostic accuracy of magnifying i-scan optical enhancement (OE) imaging for diagnosing the LBC sign in patients with different levels of risk for gastric cancer in a Mexican clinical practice. Patients and methods Patients with a history of peptic ulcer and symptoms of dyspepsia or gastroesophageal reflux disease were enrolled. Diagnosis of GIM was made at the predetermined anatomical location and white light endoscopy and i-scan OE Mode 1 were captured at the two predetermined biopsy sites (antrum and pyloric regions). Results A total of 328 patients were enrolled in this study. Overall GIM prevalence was 33.8 %. The GIM distribution was 95.4 % in the antrum and 40.5 % in the corpus. According to the Operative Link on Gastritis/Intestinal-Metaplasia Assessment staging system, only two patients (1.9 %) were classified with high-risk stage disease. Sensitivity, specificity, positive​ and negative predictive values, positive and negative likelihood ratios, and accuracy of both methods (95 % C. I.) were 0.50 (0.41-0.60), 0.55 (0.48-0.62), 0.36 (0.31-0.42), 0.68 (0.63-0.73), 1.12 (0.9-1.4), 0.9 (0.7-1.1), and 0.53 (0.43-0.60) for WLE, and 0.96 (0.90-0.99), 0.91 (0.86-0.94), 0.84 (0.78-0.89), 0.98 (0.94-0.99), 10.4 (6.8-16), 0.05 (0.02-0.12), and 0.93 (0.89-0.95), respectively. The kappa concordance was 0.67 and the reliability coefficient was 0.7407 for interobserver variability. Conclusions Our study demonstrated the high performance of magnifying i-scan OE imaging for endoscopic diagnosis of GIM in Mexican patients.

Identificación de un brote de SARSCoV-2 (Covid-19) en un centro gerontológico de la Ciudad de México.

OBJECTIVE: To describe a Covid-19 outbreak in a gerontological center in Mexico City. MATERIAL AND METHODS: Cross-sectional study in older adults. The association of risk factors for dying from Covid-19 was analyzed using a multiple logistic regression model. RESULTS: One hundred and two elders with an average age of 82.5 ± 8.8 years were included. Fifty-five (54%) tested positive and 47 (46%) were negative for the new coronavirus. Using the multiple logistic regression model, people with frailty had an OR of 11.6 of dying from Covid-19 compared to robust people (p-value = 0.024). CONCLUSION: The Covid-19 outbreak was initially caused by a resident of the center and spread by cross infection. In vulnerable populations, early detection, isolation, and follow-up of contacts should be carried out, as well as the identification of risk factors in order to reduce the spread and mortality caused by SARSCoV-2.
