Objective: To characterize variables associated with referral to the emergency department following Telemedicine consultation during the COVID-19 pandemic. Methods: Cross-sectional retrospective study conducted between March and May 2020, with a sample of 500 adult patients. The inclusion criterion was the manifestation of respiratory symptoms, regardless of type. Results: The mean age of patients was 34.7±10.5 years, and 59% were women. Most patients (62.6%) perceived their own health status as malaise and some (41.4%) self-diagnosed COVID-19. Cough (74.4%), rhinorrhea (65.6%), sore throat (38.6%) and sneezing (20.6%) were the most common infection-related symptoms. Overall, 29.4% and 16% of patients reported dyspnea and chest pain, respectively. The Roth score was calculated for a sizeable number of patients (67.6%) and was normal, moderately altered or severely altered in 83.5%, 10.7% and 5.6% of patients, respectively. The percentage of suspected COVID-19 cases was 67.6%. Of these, 75% were managed remotely and only one quarter referred for emergency assessment. Conclusion: Telemedicine assessment is associated with reclassification of patient's subjective impression, better inspection of coronavirus disease 2019 and identification of risk patients. Referral is therefore optimized to avoid inappropriate in-person assessment, and low-risk patients can be properly guided. Telemedicine should be implemented in the health care system as a cost-effective strategy for initial assessment of acute patients.
Pollinosis is sub-diagnosed and rarely studied in tropical countries. Cashew tree pollen has been reported as an allergen source although the knowledge of its immunoglobulin E (IgE)-reactive molecules is lacking. Therefore, this work aimed to identify IgE-reactive molecules and provide a proteomic profile of this pollen. From the 830 proteins identified by shotgun analysis, 163 were annotated to gene ontology, and a list of 39 proteins filtered for high confidence was submitted to the Allfam database where nine were assigned to allergenic families. Thus, 12 patients from the northeast of Brazil with persistent allergic rhinitis and aggravation of symptoms during cashew flowering season were selected. Using a 2D-based approach, we identified 20 IgE-reactive proteins, four already recognized as allergens, including a homolog of the birch isoflavone-reductase (Bet v 6). IgE-reactivity against the extract in native form was confirmed for five patients in ELISA, with three being positive for Bet v 6. Herein, we present a group of patients with rhinitis exposed to cashew tree pollen with the first description of IgE-binding proteins and a proteomic profile of the whole pollen. Cashew tree pollen is considered an important trigger of rhinitis symptoms in clinical practice in the northeast of Brazil, and the elucidation of its allergenic molecules can improve the diagnostics and treatment for allergic patients.
A parada cardíaca, ou cardiorrespiratória (PCR), súbita corresponde a cerca de metade de todas as mortes de causa cardiovascular e é uma das principais causas de morte de adultos em países desenvolvidos e em desenvolvimento. O tratamento eficaz da PCR consiste em atendimento imediato, com ressuscitação cardiopulmonar (RCP) de alta qualidade, desfibrilação precoce em ritmos chocáveis, identificação da causa da PCR e cuidados pós-parada. A despeito de diretrizes de RCP constantemente atualizadas e amplamente divulgadas, a mortalidade por PCR ainda é muito elevada e há grande heterogeneidade de causas de PCR e do prognóstico inerente a cada causa. Pacientes em PCR cujo ritmo inicial é não-chocável, geralmente apresentam maior desafio em relação à identificação da causa da PCR. Neste contexto, o ultrassom manuseado pelo socorrista e utilizado como extensão do exame físico durante a RCP está associado a maior rapidez e maior número de diagnósticos específicos e, consequentemente, maior número de tratamentos específicos e potencial melhor prognóstico. O ultrassom também pode ser utilizado para diagnóstico da PCR, assim como para monitorizar a qualidade de RCP, guiar procedimentos e também inferir prognóstico. Na última década, um grande número de publicações científicas embasaram a utilização do ultrassom nas manobras de RCP, com demonstração de, em alguns subgrupos, melhor prognóstico. Atualmente, o ultrassom está incorporado nas unidades de emergência de excelência como recurso fundamental a ser utilizado em diversas situações. O objetivo desta revisão é fornecer informações sobre o estado da arte da utilização do ultrassom na PCR.
Objective The present study aims to assess the feasibility and patient satisfaction of teleoncology orientation in a vulnerable population of breast cancer patients assessed in a government health system during the coronavirus pandemic in 2020. Methods Eligible patients received an invitation to receive remote care to minimize exposure to an environment in which the risk of respiratory infection was present. The means of communication was telephone through an application that allows free conversation with no charge. An anonymous-response questionnaire based on a Likert-type scale was sent through a cell phone application or e-mail directly to each patient or close relative of the patient immediately after teleconsultation. Responses to the questions, which addressed utility, facility, interface quality, interaction quality, reliability, satisfaction, and interest in future evaluation, were compiled and analyzed. Results A total of 176 eligible patients scheduled for consultation were evaluated and 98 were included. Seventy (71.4%) successfully undertook the teleorientation. The questionnaire was submitted by 43 (61.4%) patients. The overall teleoncology orientation was classified as very positive by 41 (95.3%) patients. Specifically, regarding the questionnaire items, 43 (100%) patients scored 4 or 5 (agreed that the teleconsultation was beneficial) concerning the facility, followed by 42 (97.2%) for the interface quality, 41 (95.3%) for both utility and interaction quality, 40 (93%) for satisfaction and interest in future evaluation, and, finally, 39 (90.6%) for reliability. Conclusion Teleoncology orientation of low-income breast cancer patients is most feasible and leads to high patient satisfaction.
Objective: To evaluate the feasibility of telemedicine using a standardized multiorgan ultrasound assessment protocol to guide untrained on-site general practitioners at a field hospital during a life-threatening crisis. Materials and Methods: We evaluated 11 inpatients with shock, with or without acute dyspnea, for whom general practitioners spontaneously requested remote evaluation by a specialist. Results: All of the general practitioners accepted the protocol and were able to position the transducer correctly, thus obtaining key images of the internal jugular vein, lungs, and inferior vena cava when guided remotely by a telemedicine physician, who interpreted all of the findings. However, only four (36%) of the on-site general practitioners obtained the appropriate key image of the heart in the left parasternal long-axis view, and only three (27%) received an immediate interpretation of an image from the remote physician. The mean evaluation time was 22.7 ± 12 min (range, 7-42 min). Conclusion: Even in life-threatening situations, untrained general practitioners may be correctly guided by telemedicine specialists to perform multiorgan point-of-care ultrasound in order to improve bedside diagnostic evaluation.
Background Feasibility and safety of ambulance transport between healthcare facilities with medical support exclusively via telemedicine are unknown. Methods This was a retrospective study with a single telemedicine center reference for satellite emergency departments of the same hospital. The study population was all critically ill patients admitted to one of the peripheral units from November 2016 to May 2020 and who needed to be transferred to the main building. Telemedicine-assisted transportation was performed by an emergency specialist. The inclusion criteria included patients above the age of 15 and initial stabilization performed at the emergency department. Unstable, intubated, ST-elevation myocardial infarction and acute stroke patients were excluded. There was a double-check of safety conditions by the nurse and the remote doctor before the ambulance departure. The primary endpoint was the number of telemedicine-guided interventions during transport. Results 2840 patients were enrolled. The population was predominantly male (53.2%) with a median age of 60 years. Sepsis was the most prevalent diagnosis in 28% of patients, followed by acute coronary syndromes (8.5%), arrhythmia (6.7%), venous thromboembolism (6.1%), stroke (6.1%), acute abdomen (3.6%), respiratory distress (3.3%), and heart failure (2.5%). Only 22 (0.8%) patients required telemedicine-assisted support during transport. Administration of oxygen therapy and analgesics were the most common recommendations made by telemedicine emergency physicians. There were no communication problems in the telemedicine-assisted group. Conclusions Telemedicine-assisted ambulance transportation between healthcare facilities of stabilized critically ill patients may be an option instead of an onboard physician. The frequency of clinical support requests by telemedicine is minimal, and most evaluations are of low complexity and easily and safely performed by trained nurses.
