ABSTRACT

Abstract Objective COVID-19 is associated with an elevated risk of thromboembolism and excess mortality. Difficulties with best anticoagulation practices and their implementation motivated the current analysis of COVID-19 patients who developed Venous Thromboembolism (VTE). Method This is a post-hoc analysis of a COVID-19 cohort, described in an economic study already published. The authors analyzed a subset of patients with confirmed VTE. We described the characteristics of the cohort, such as demographics, clinical status, and laboratory results. We tested differences amid two subgroups of patients, those with VTE or not, with the competitive risk Fine and Gray model. Results Out of 3186 adult patients with COVID-19, 245 (7.7%) were diagnosed with VTE, 174 (5.4%) of them during admission to the hospital. Four (2.3% of these 174) did not receive prophylactic anticoagulation and 19 (11%) discontinued anticoagulation for at least 3 days, resulting in 170 analyzed. During the first week of hospitalization, the laboratory most altered results were C-reactive protein and D-dimer. Patients with VTE were more critical, had a higher mortality rate, worse SOFA score, and, on average, 50% longer hospital stay. Conclusion Proven VTE incidence in this severe COVID-19 cohort was 7.7%, despite 87% of them complying completely with VTE prophylaxis. The clinician must be aware of the diagnosis of VTE in COVID-19, even in patients receiving proper prophylaxis.

ABSTRACT

OBJECTIVE: Coronavirus disease 2019 (COVID-19) is associated with high mortality among hospitalized patients and incurs high costs. Severe acute respiratory syndrome coronavirus 2 infection can trigger both inflammatory and thrombotic processes, and these complications can lead to a poorer prognosis. This study aimed to evaluate the association and temporal trends of D-dimer and C-reactive protein (CRP) levels with the incidence of venous thromboembolism (VTE), hospital mortality, and costs among inpatients with COVID-19. METHODS: Data were extracted from electronic patient records and laboratory databases. Crude and adjusted associations for age, sex, number of comorbidities, Sequential Organ Failure Assessment score at admission, and D-dimer or CRP logistic regression models were used to evaluate associations. RESULTS: Between March and June 2020, COVID-19 was documented in 3,254 inpatients. The D-dimer level ≥4,000 ng/mL fibrinogen equivalent unit (FEU) mortality odds ratio (OR) was 4.48 (adjusted OR: 1.97). The CRP level ≥220 mg/dL OR for death was 7.73 (adjusted OR: 3.93). The D-dimer level ≥4,000 ng/mL FEU VTE OR was 3.96 (adjusted OR: 3.26). The CRP level ≥220 mg/dL OR for VTE was 2.71 (adjusted OR: 1.92). All these analyses were statistically significant (p<0.001). Stratified hospital costs demonstrated a dose-response pattern. Adjusted D-dimer and CRP levels were associated with higher mortality and doubled hospital costs. In the first week, elevated D-dimer levels predicted VTE occurrence and systemic inflammatory harm, while CRP was a hospital mortality predictor. CONCLUSION: D-dimer and CRP levels were associated with higher hospital mortality and a higher incidence of VTE. D-dimer was more strongly associated with VTE, although its discriminative ability was poor, while CRP was a stronger predictor of hospital mortality. Their use outside the usual indications should not be modified and should be discouraged.

ABSTRACT

OBJECTIVES: A good health care does not only depend on good medical practice, but also needs great management of its resources, which are generally short. In this sense, PROAHSA has been training new health managers since 1972. With the arrival of the COVID-19 pandemic, it was clear that medicine will go through a new phase, where telehealth will be present in this "Improved Normal". This report is about how a pilot teleconsultation study was carried out for HCFMUSP patients through the Scrum-like framework. It is to deploy a pilot of remote assistance involving a doctor and a patient in the Ambulatory of Hepatology and Liver Transplantation of HCFMUSP. METHODS: We applied the Scrum-like framework to carry out this work with an interdisciplinary multifunctionality team. RESULTS: A full telemedicine service flow was implemented within eight weeks using existing infrastructure and resources implementing the Scrum methodology. Twenty-three teleconsultations were scheduled and eight guides built. CONCLUSION: Scrum framework has a great potential to improve the training of students and to conclude pilot projects.

ABSTRACT

Trinta e seis canais artificiais curvos confeccionados em blocos de resina epóxi transparente foram instrumentados manualmente por limas de níquel-titânio Nitiflex com pontas ISO (Grupo A) e por limas de níquel-titânio Profile Series 29 (grupo B). Com o auxílio de uma plataforma metálica especificamente confeccionada, foi empregada a técnica da dupla exposição radiográfica. As radiografias resultantes foram posiocionadas em um scanner, e as imagens, digitalizadas (40X), visualizadas no monitor de um microcomputador. A aferição de transporte apical foi realizada pelo sofware Digora for Windows 1,51. Os dados obtidos foram avaliados estatisticamente pela análise de variância a um critério (Anova) ao nível de significância de 5 por cento. Não foram observadas diferenças estatisticamente significantes entre os dois grupos experimentais, com relação à intesidade de transporte apical. O tempo médio despendido para instrumetação dos canais do Grupo A foi significativamente menor

ABSTRACT

O objetivo deste trabalho foi comparar a açäo das limas de aço inoxidável e de níquel-titânio com relaçäo à ocorrência de transporte apical em canais mesiais curvos de primeiros molares superiores extraídos, por meio da dupla exposiçäo radiográfica. Os resultados mostraram näo haver diferenças estatísticas significativas entre os dois instrumentos

ABSTRACT

É descrito o retratamento endodôntico de um incisivo lateral superior com dois canais. O diagnóstico de fusão, geminação ou dens invaginatus não pôde ser precisamente estabelecido, devido a características anatômicas conflitantes e à intervenção endodôntica anterior, que suprimiu a configuração original da câmara pulpar

ABSTRACT

Vinte dentes unirradiculados extraídos foram instumentados e obturados pela técnica híbrida de Tagger. Foram comparadas as radiografias processadas logo após a condensaçäo lateral do terço apical, com aquelas realizadas depois do emprego dos compactadores de McSpadden. Concluímos que o emprego adequado dos compactadores näo interferiu na obturaçäo do canal em seu terço apical

ABSTRACT

Foram utilizadas 40 raízes de dentes molares humanos (superiores e inferiores) extraídos, que foram divididas em dois grupos distintos. O primeiro grupo composto pelas raízes mesiais dos molares inferiores e mesiovestibulares dos superiores, enquanto o segundo grupo foi formado pelas raízes distais dos molares inferiores e palatinas dos superiores. Os canais foram instrumentados e, entäo, obturados pelas técnicas da condensaçäo lateral e Thermafil. Os dentes tiveram suas superfícies externas impermeabilizadas, com exceçäo da porçäo apical, sendo entäo, imersos em tinta da India (nanquim), aplicando-se vácuo por determinado período. Findo o tempo preestabelecido de sua imersäo, as raízes foram lavadas, limpas e secadas, quando entäo sofreram desmineralizaçäo, desidrataçäo e clareaçäo, tornando-se transparentes. Realizaram-se mensuraçöes das infiltraçöes lineares, e os dados obtidos foram avaliados, tabulados e submetidos à análise estatística. Pôde-se entäo concluir que: em relaçäo à capacidade seladora, näo houve diferença estatística entre as técnicas de condensaçäo lateral e do Thermafil; em canais curvos e atrésicos (mesiovestibulares de molares superiores e mesiais de molares inferiores) houve maior infiltraçäo do que nos canais amplos e retos (distais de molares inferiores e palatinos de molares superiores)

ABSTRACT

Os autores apresentam um caso de traumatismo dental com fraturas radiculares de incisivos centrais superiores permanentes. Devido ao diagnóstico equivocado de necrose pulpar, um dos elementos recebeu intervençäo endodôntica, o que impossibilitou a coalescência espontânea da fratura. O outro elemento teve sua fratura consolidada espontaneamente após apresentar evidências radiográficas de reabsorçäo interna autolimitada e mineralizaçäo pulpar do segmento apical da raiz
