Telemedicine ultrasound assessment for placenta accreta spectrum: utility and interobserver reliability of asynchronous remote imaging review

Objective: Management of patients with placenta accreta spectrum (PAS) by trained multidisciplinary teams is associated with improved outcomes. Ultrasound can predict intraoperative risks, but expert ultrasound imaging of PAS is often limited. Telemedicine is used increasingly in obstetrics, permitting expert consultation when essential resources are not available locally. Our objective was to evaluate the feasibility of teleconsultation using standardized ultrasound image acquisition and reporting, and to correlate prognosis with intraoperative findings in patients at risk for PAS. Methods: A total of 12 PAS imaging experts (teleconsultants) were selected to asynchronously review deidentified standardized grayscale and color Doppler ultrasound images for five patients who had completed treatment for PAS, resulting in 60 individual teleconsultations. All patients were managed at a center using standardized imaging acquisition and intraoperative topographic classification to individualize surgical management. Teleconsultants reported the predicted topographic classification and recommended a surgical approach based on the topographic classification algorithm. Prognoses were compared with that reported by the local sonologist and with intraoperative findings. Results: In all five patients, local sonologist prognosis and antenatal topographic classification was confirmed during surgery and the final surgical approach matched that which was recommended preoperatively. Teleconsultant antenatal evaluation and management plans matched those of the local team in 71.7% of the cases. When reports differed, PAS severity was overestimated in nine reviews (16.9%) and was underestimated in six reviews (11.3%). Conclusion: Remote imaging teleconsultation provides accurate prenatal staging in most patients at risk for PAS. Teleconsultation is a feasible strategy to improve prenatal imaging, management planning, and guidance for local teams in settings with limited healthcare resources

Evaluación de la ansiedad preoperatoria en pacientes sometidos a anestesia general. Estudio observacional

Introduction. Anxiety is an adaptive response of the human being to danger. The surgical anesthetic act is considered a generator of anxiety that is related to greater vulnerability and difficult control of postoperative pain, prolonged hospital stay, higher rate of anesthetic events and vulnerability to infections. This study aims to estimate the prevalence of preoperative anxiety in a group of patients undergoing surgery under general anesthesia using the Amsterdam Preoperative Anxiety and Information Scale (APAIS). Methods. A cross-sectional observational study performed with surgical patients who received general anesthesia at a third-level hospital. Sociodemographic and clinical information were obtained. Prevalence of preoperative anxiety was estimated by using the APAIS scale (cut of 11) and potential associated factors were evaluated. A descriptive analysis and crude odds ratios were calculated. In addition, a logistic regression model was constructed to adjust the effect of covariates. Results. Prevalence of anxiety was 13% [IC95% 7%-18%]. No variables were found to be significantly associated with the presence of anxiety. 76.8% of the participants had a low need for information. Women, outpatients, ASA I classification and patients under major surgery without a history of previous surgical procedures presented a higher frequency of anxiety. The majority of patients presented a low need for information (76.8%). After the adjusted analysis, there were no variables related to the presentation of anxiety. Conclusions. A low prevalence of anxiety and a low need for information on the part of the participants were documented. It is necessary to do further research in this area in Colombia.Introducción. La ansiedad es una respuesta adaptativa del ser humano ante el peligro. El acto anestésico quirúrgico como generador de ansiedad se relaciona con mayor vulnerabilidad y difícil control del dolor postoperatorio, estancia hospitalaria prolongada, mayor tasa de accidentes anestésicos y vulnerabilidad a infecciones. Este estudio estimó la prevalencia de ansiedad preoperatoria en un grupo de pacientes sometidos a anestesia general mediante la escala de Ansiedad Preoperatoria y de Información de Ámsterdam (APAIS). Métodos. Estudio observacional de corte transversal con pacientes que recibieron anestesia general en un hospital de III nivel de atención. Se obtuvo información sociodemográfica y clínica. Se determinó la prevalencia de ansiedad preoperatoria mediante la escala APAIS (utilizando un punto de corte de 11) y los potenciales factores asociados. Se realizó un análisis descriptivo y se calcularon odds ratios para las asociaciones. Además, se construyó un modelo de regresión logística para ajustar el efecto de las covariables en la presentación de ansiedad. Resultados. La prevalencia de ansiedad fue de 13% [IC95% 7%-18%]. Las mujeres, los pacientes ambulatorios, clasificación ASA I y sometidos a cirugía mayor sin antecedentes de procedimientos quirúrgicos previos presentaron una mayor frecuencia de ansiedad. La mayoría de los pacientes presentaban una baja necesidad de información (76,8%). Tras el análisis ajustado, no se encontraron variables asociadas de forma importante a la presentación de ansiedad. Conclusiones. Se documentó una baja prevalencia de ansiedad y una baja necesidad de información por parte de los participantes. Se requiere continuar la investigación en el área en Colombia. &nbsp

Risk factors associated with adverse fetal outcomes in pregnancies affected by Coronavirus disease 2019 (COVID-19): a secondary analysis of the WAPM study on COVID-19.

Objectives To evaluate the strength of association between maternal and pregnancy characteristics and the risk of adverse perinatal outcomes in pregnancies with laboratory confirmed COVID-19. Methods Secondary analysis of a multinational, cohort study on all consecutive pregnant women with laboratory-confirmed COVID-19 from February 1, 2020 to April 30, 2020 from 73 centers from 22 different countries. A confirmed case of COVID-19 was defined as a positive result on real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay of nasal and pharyngeal swab specimens. The primary outcome was a composite adverse fetal outcome, defined as the presence of either abortion (pregnancy loss before 22 weeks of gestations), stillbirth (intrauterine fetal death after 22 weeks of gestation), neonatal death (death of a live-born infant within the first 28 days of life), and perinatal death (either stillbirth or neonatal death). Logistic regression analysis was performed to evaluate parameters independently associated with the primary outcome. Logistic regression was reported as odds ratio (OR) with 95% confidence interval (CI). Results Mean gestational age at diagnosis was 30.6+/-9.5 weeks, with 8.0% of women being diagnosed in the first, 22.2% in the second and 69.8% in the third trimester of pregnancy. There were six miscarriage (2.3%), six intrauterine device (IUD) (2.3) and 5 (2.0%) neonatal deaths, with an overall rate of perinatal death of 4.2% (11/265), thus resulting into 17 cases experiencing and 226 not experiencing composite adverse fetal outcome. Neither stillbirths nor neonatal deaths had congenital anomalies found at antenatal or postnatal evaluation. Furthermore, none of the cases experiencing IUD had signs of impending demise at arterial or venous Doppler. Neonatal deaths were all considered as prematurity-related adverse events. Of the 250 live-born neonates, one (0.4%) was found positive at RT-PCR pharyngeal swabs performed after delivery. The mother was tested positive during the third trimester of pregnancy. The newborn was asymptomatic and had negative RT-PCR test after 14 days of life. At logistic regression analysis, gestational age at diagnosis (OR: 0.85, 95% CI 0.8-0.9 per week increase; pPeer reviewe

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
