Outcomes in non-ST-segment elevation myocardial infarction complicated by in-hospital cardiac arrest based on management strategy.

BACKGROUND: There are limited data on in-hospital cardiac arrest (IHCA) complicating non-ST-segment-elevation myocardial infarction (NSTEMI) based on management strategy. METHODS: We used National Inpatient Sample (2000-2017) to identify adults with NSTEMI (not undergoing coronary artery bypass grafting) and concomitant IHCA. The cohort was stratified based on use of early (hospital day 0) or delayed (≥hospital day 1) coronary angiography (CAG), percutaneous coronary intervention (PCI), and medical management. Outcomes included incidence of IHCA, in-hospital mortality, adverse events, length of stay, and hospitalization costs. RESULTS: Of 6,583,662 NSTEMI admissions, 375,873 (5.7 %) underwent early CAG, 1,133,143 (17.2 %) received delayed CAG, 2,326,391 (35.3 %) underwent PCI, and 2,748,255 (41.7 %) admissions were managed medically. The medical management cohort was older, predominantly female, and with higher comorbidities. Overall, 63,085 (1.0 %) admissions had IHCA, and incidence of IHCA was highest in the medical management group (1.4 % vs 1.1 % vs 0.7 % vs 0.6 %, p < 0.001) compared to early CAG, delayed CAG and PCI groups, respectively. In adjusted analysis, early CAG (adjusted OR [aOR] 0.67 [95 % confidence interval {CI} 0.65-0.69]; p < 0.001), delayed CAG (aOR 0.49 [95 % CI 0.48-0.50]; p < 0.001), and PCI (aOR 0.42 [95 % CI 0.41-0.43]; p < 0.001) were associated with lower incidence of IHCA compared to medical management. Compared to medical management, early CAG (adjusted OR 0.53, CI: 0.49-0.58), delayed CAG (adjusted OR 0.34, CI: 0.32-0.36) and PCI (adjusted OR 0.19, CI: 0.18-0.20) were associated with lower in-hospital mortality (all p < 0.001). CONCLUSION: Early CAG and PCI in NSTEMI was associated with lower incidence of IHCA and lower mortality among NSTEMI-IHCA admissions.

Validity of the Espiro Mobile Application in the Interpretation of Spirometric Patterns: An App Accuracy Study.

Spirometry is a pulmonary function test where correct interpretation of the results is crucial for accurate diagnosis of disease. There are online tools to assist in the interpretation of spirometry results; however, as yet none are validated. We evaluated the interpretation accuracy of the Espiro app using pulmonologist interpretations as the gold standard. This is an observational descriptive study in which 118 spirometry results were interpreted by the Espiro app, two pulmonologists, two primary care physicians, and two residents of a primary care training program. We determined the interpretation accuracy of the Espiro app and the concordance of the pattern and severity interpretation between the Espiro app and each of the observers using Cohen's kappa coefficient (k). We obtained a sensitivity and specificity for the Espiro app of 97.5% (95% confidence interval (CI): 86.8-99.9%) and 94.9% (95%CI: 87.4-98.6%) with pulmonologist 1 and 100% (95%CI: 91.6-100%) and 98.7% (95%CI: 92.9-99.9%) with pulmonologist 2. The concordance for the pattern interpretation was greater than k 0.907, representing almost perfect agreement. The concordance of the severity interpretation was greater than k 0.807, representing substantial to almost perfect agreement. We concluded that the Espiro app is a valid tool for spirometry interpretation.

Reducing rates of readmission and development of an outpatient management plan in pulmonary hypertension: lessons from congestive heart failure management.

Pulmonary hypertension currently has minimal guidelines for outpatient disease management. Congestive heart failure studies, however, have shown effectiveness of disease management plans in reducing all-cause mortality and all-cause and congestive heart failure-related hospital readmissions. Heart failure exacerbation is a common reason for readmission in both pulmonary hypertension and congestive heart failure. Our aim was to review individual studies and comprehensive meta-analyses to identify effective congestive heart failure interventions that can be used to develop similar disease management plans for pulmonary hypertension. A comprehensive literature review from 1993 to 2019 included original articles, systematic reviews, and meta-analyses. We reviewed topics of outpatient congestive heart failure interventions to decrease congestive heart failure mortality and readmission and patient management strategies in congestive heart failure. The most studied interventions included case management, multidisciplinary intervention, structured telephone strategy, and tele-monitoring. Case management showed decreased all-cause mortality at 12 months, all-cause readmission at 12 months, and congestive heart failure readmission at 6 and 12 months. Multidisciplinary intervention resulted in decreased all-cause readmission and congestive heart failure readmission. There was some discrepancy on effectiveness of tele-monitoring programs in individual studies; however, meta-analyses suggest tele-monitoring provided reduced all-cause mortality and risk of congestive heart failure hospitalization. Structured telephone strategy had similar results to tele-monitoring including decreased risk of congestive heart failure hospitalization, without effect on mortality. Extrapolating from congestive heart failure data, it seems strategies to improve the health of pulmonary hypertension patients and development of comprehensive care programs should include structured telephone strategy and/or tele-monitoring, case management strategies, and multidisciplinary interventions.

Successful mobile extracorporeal membrane oxygenator for COVID-19 severe respiratory failure.

High volume extracorporeal membrane oxygenation (ECMO) centers have developed mobile ECMO programs in recent years to facilitate the implementation of ECMO support at hospitals with lower capabilities, and transfer these patients for further care. We report a case of mobile ECMO on a patient with coronavirus disease 2019-related acute respiratory distress syndrome, and discuss the potential application in the current severe acute respiratory syndrome coronavirus 2 pandemic.

'Minimalist approach' for transcatheter mitral valve replacement using intracardiac echocardiography and conscious sedation: a case series.

BACKGROUND: Transcatheter aortic valve implantation operators have adapted to a less invasive technique by foregoing the use of general anaesthesia and transoesophageal echocardiography. This is known as a 'minimalist approach'. This approach has yet to be explored in transcatheter mitral valve replacement (TMVR). Two patients with high perioperative risk underwent TMVR using only monitored conscious sedation (CS) and intracardiac echocardiography (ICE). CASE SUMMARY: The patients were symptomatic and required treatment of severe mitral regurgitation and severe mitral stenosis in a mitral valve ring and prosthetic mitral valve, respectively. With the use of an antegrade transseptal approach, the procedure was conducted under CS using ICE only. After placement of the prosthetic mitral valve, the valve was assessed by advancing the ICE catheter through the interatrial septal defect and no significant paravalvular leak occurred. In one case, ad hoc treatment of right to left shunting was successfully pursued. Valve function was excellent immediately and at 24 h after implantation and resulted in significant haemodynamic improvement. CONCLUSION: With more TMVR cases being conducted, the 'minimalist approach' with CS and ICE may be considered in selected cases.

Hepatitis C Virus NAT-Positive Solid Organ Allografts Transplanted Into Hepatitis C Virus-Negative Recipients: A Real-World Experience.

BACKGROUND AND AIMS: Hepatitis C virus (HCV)-viremic organs are underutilized, and there is limited real-world experience on the transplantation of HCV-viremic solid organs into recipients who are HCV negative. APPROACH AND RESULTS: Patients listed or being evaluated for solid organ transplant after January 26, 2018, were educated and consented by protocol on the transplantation of HCV-viremic organs. All recipients were HCV nucleic acid test and anti-HCV antibody negative at the time of transplant and received an HCV-viremic organ. The primary outcome was sustained virological response (SVR) at 12 weeks after completion of direct-acting antiviral (DAA) therapy (SVR12 ). Seventy-seven patients who were HCV negative underwent solid organ transplantation from a donor who was HCV viremic. No patients had evidence of advanced hepatic fibrosis. Treatment regimen and duration were at the discretion of the hepatologist. Sixty-four patients underwent kidney transplant (KT), and 58 KT recipients had either started or completed DAA therapy. Forty-one achieved SVR12 , 10 had undetectable viral loads but are not eligible for SVR12 , and 7 remain on treatment. One KT recipient was a nonresponder because of nonstructural protein 5A resistance. Four patients underwent liver transplant and 2 underwent liver-kidney transplant. Three patients achieved SVR12 , 1 has completed DAA therapy, and 2 remain on treatment. Six patients underwent heart transplant and 1 underwent heart-kidney transplant. Six patients achieved SVR12 and 1 patient remains on treatment. CONCLUSIONS: Limited data exist on the transplantation of HCV-viremic organs into recipients who are HCV negative. Our study is the largest to describe a real-world experience of the transplantation of HCV-viremic organs into recipients who are aviremic. In carefully selected patients, the use of HCV-viremic grafts in the DAA era appears to be efficacious and well tolerated.

Resultados y seguimiento de la rehabilitación vestibular / Vestibular rehabilitation outcomes and follow-up

INTRODUCCIÓN Y OBJETIVO: La rehabilitación vestibular (RV) consiste en la realización de un programa de ejercicios orientado hacia las necesidades específicas del paciente. La colaboración y el apoyo psicológico son también elementos clave para conseguir una óptima recuperación. Las técnicas han evolucionado en las últimas décadas y disponemos del suficiente conocimiento para avalar su eficacia, que intentaremos ir presentando a lo largo de este capítulo. MÉTODO: Revisión narrativa. RESULTADOS: La RV es un tratamiento seguro y eficaz. Es recomendable una intervención temprana a fin de prevenir las caídas y aliviar los síntomas cuanto antes; pero los pacientes con alteraciones crónicas también se benefician. La RV es efectiva en trastornos vestibulares periféricos y centrales. Se desconoce la frecuencia, duración óptima y número total de visitas necesarias para obtener los mejores resultados, pero dependerá de la respuesta del paciente. No hay un programa único que pueda ser eficaz a todo el que sufra de un trastorno vestibular. CONCLUSIÓN: La RV es actualmente el estándar de tratamiento para muchos tipos de patología vestibular y creemos que debe ser proporcionado por fisioterapeutas especializados en esta terapia

INTRODUCTION AND OBJECTIVE: Vestibular rehabilitation (VR) typically consists of the provision of a customized exercise program targeted toward the patient's specific needs. Patient education and psychological support are also key elements to optimal recovery. The techniques have evolved over the past few decades, and there is reliable research into the efficacy of vestibular exercises, wich we will try to present throughout this chapter. METHOD: Narrative review. RESULTS: VR is a safe and effective treatment. Early intervention is advised for falls prevention and symptom management; however, symptomatic patients with chronic vestibular disorders may still demonstrate benefit. Persons with both central and peripheral vestibular disorders improve with VR. The frequency, optimal treatment duration, and total number of physical therapy visits for best results are unknown. Exercise programs must be regulated and dosed based on the response of the patient. No one-exercise program is effective for all persons with vestibular disorders. CONCLUSION: Vestibular rehabilitation now is the standard of care for many types of vestibular pathology and we believe should be provided by physical and occupational therapists who have specialized training beyond the entry-level degree

Colesteatoma de conducto auditivo externo: estudio de una serie de casos / Cholesteatoma of the external auditory canal: case series study

INTRODUCCIÓN Y OBJETIVOS: El colesteatoma de conducto auditivo externo (CCAE) es un proceso patológico poco frecuente, caracterizado por la invasión de tejido escamoso en un área del canal auditivo, que progresa hasta la destrucción ósea. Debido a la escasez de casos publicados hemos considerado de utilidad esta revisión. MATERIAL Y MÉTODOS: Estudio prospectivo y observacional desde el año 2000, de 18 pacientes diagnosticados clínicamente de CCAE en nuestro servicio de ORL. RESULTADOS: El porcentaje de hombres y mujeres es similar, con una edad media de diagnóstico de 60 años. La localización más frecuente es póstero-inferior y en la mayor parte de casos el origen es primario. La otalgia, la otorrea y la hipoacusia fueron los síntomas principales, siendo menos habitual el prurito y excepcional la debilidad facial. En general el tratamiento es conservador, pero resultó necesario el abordaje quirúrgico en un tercio de pacientes mediante canaloplastia, siguiendo el esquema expuesto, o la mastoidectomía, en función de la extensión de las lesiones. CONCLUSIONES: Aunque desconocemos los mecanismos patogénicos responsables de la formación y desarrollo del CCAE, la inclusión de queratina entre el epitelio y el hueso, con la participación del periostio, parecen ser los desencadenantes del proceso. El diagnóstico es clínico y su extensión determina el empleo de un tratamiento local o quirúrgico, que suele ser resolutivo

INTRODUCTION: External auditory canal cholesteatoma (EACC) is a rare entity characterized by the invasion of squamous tissue in the auditory canal, that progresses to bone destruction. Due to the scarcity of published cases of EACC, we have deemed useful this review. MATERIAL AND METHODS: Prospective and observational study from the year 2000 to the present in 18 patients clinically diagnosed with EACC in our ORL service. RESULTS: The percentage of men and women is similar, with a mean age at diagnosis of 60 years. The most frequently location was postero-inferior, and in most cases, the origin is primary. Otalgia, otorrhea and subjective hearing loss were the main symptoms, being less common the pruritus and exceptional facial weakness. Overall, the treatment is conservative, but it was necessary surgical treatment on one-third of the patients, performing canaloplasty or mastoidectomy, according to the extent of injuries. CONCLUSIONS: Although we do not know the genesis and pathogenic mechanisms responsible of EACC formation and development, the inclusion of keratin between the epithelium and bone, with the participation of the periosteum, seems to be the trigger of this process. The diagnosis is clinical, and its extension determines the use of a local or surgical treatment, which is usually resolutive

Heart failure in frail, older patients: we can do 'MORE'.

A comprehensive approach is necessary in managing heart failure in frail older adults. To provide optimal care, physicians need to draw on knowledge from the fields of internal medicine, geriatrics, and cardiology. The acronym "MORE" is a mnemonic for what heart failure management should include: multidisciplinary care, attention to other (ie, comorbid) diseases, restrictions (of salt, fluid, and alcohol), and discussion of end-of-life issues.
