Comparison between high-flow nasal oxygen (HFNO) alternated with non-invasive ventilation (NIV) and HFNO and NIV alone in patients with COVID-19: a retrospective cohort study.

BACKGROUND: Non-invasive respiratory support (conventional oxygen therapy [COT], non-invasive ventilation [NIV], high-flow nasal oxygen [HFNO], and NIV alternated with HFNO [NIV + HFNO] may reduce the need for invasive mechanical ventilation (IMV) in patients with COVID-19. The outcome of patients treated non-invasively depends on clinical severity at admission. We assessed the need for IMV according to NIV, HFNO, and NIV + HFNO in patients with COVID-19 according to disease severity and evaluated in-hospital survival rates and hospital and intensive care unit (ICU) lengths of stay. METHODS: This cohort study was conducted using data collected between March 2020 and July 2021. Patients ≥ 18 years admitted to the ICU with a diagnosis of COVID-19 were included. Patients hospitalized for < 3 days, receiving therapy (COT, NIV, HFNO, or NIV + HFNO) for < 48 h, pregnant, and with no primary outcome data were excluded. The COT group was used as reference for multivariate Cox regression model adjustment. RESULTS: Of 1371 patients screened, 958 were eligible: 692 (72.2%) on COT, 92 (9.6%) on NIV, 31 (3.2%) on HFNO, and 143 (14.9%) on NIV + HFNO. The results for the patients in each group were as follows: median age (interquartile range): NIV (64 [49-79] years), HFNO (62 [55-70] years), NIV + HFNO (62 [48-72] years) (p = 0.615); heart failure: NIV (54.5%), HFNO (36.3%), NIV + HFNO (9%) (p = 0.003); diabetes mellitus: HFNO (17.6%), NIV + HFNO (44.7%) (p = 0.048). > 50% lung damage on chest computed tomography (CT): NIV (13.3%), HFNO (15%), NIV + HFNO (71.6%) (p = 0.038); SpO2/FiO2: NIV (271 [118-365] mmHg), HFNO (317 [254-420] mmHg), NIV + HFNO (229 [102-317] mmHg) (p = 0.001); rate of IMV: NIV (26.1%, p = 0.002), HFNO (22.6%, p = 0.023), NIV + HFNO (46.8%); survival rate: HFNO (83.9%), NIV + HFNO (63.6%) (p = 0.027); ICU length of stay: NIV (8.5 [5-14] days), NIV + HFNO (15 [10-25] days (p < 0.001); hospital length of stay: NIV (13 [10-21] days), NIV + HFNO (20 [15-30] days) (p < 0.001). After adjusting for comorbidities, chest CT score and SpO2/FiO2, the risk of IMV in patients on NIV + HFNO remained high (hazard ratio, 1.88; 95% confidence interval, 1.17-3.04). CONCLUSIONS: In patients with COVID-19, NIV alternating with HFNO was associated with a higher rate of IMV independent of the presence of comorbidities, chest CT score and SpO2/FiO2.

Acolhimento de travestis e transexuais na atenção primária à saúde: uma revisão bibliográfica / Accommodation of transvestis and transsexuals in primary health care: a literature review

Objetivo: analisar, conhecer sobre o acolhimento de Travestis e Transexuais na Atenção Primária à Saúde. Métodos: trata-se de uma pesquisa bibliográfica de caráter exploratório com abordagem qualitativa, na qual realizou-se uma busca no período de março a junho de 2020 em base de dados confiáveis, em português, dentre os quais Scientifc Electronic Library Online Brasil (SciELO), Google Scholar e o site do Ministério da Saúde podem ser citados, dentre outros periódicos de referência na área.Resultados:após análise detalhada das publicações, verificou-se 16 publicações exploravam realmente o tema em questão, sendo utilizados para a construção da pesquisa. Considerações Finais: há um método principal para que o acolhimento seja qualificado e holístico, que é acapacitação do enfermeiro juntamente com a educação continuada para que ele ajude a mudar a realidade da vida do público Transno âmbito de saúde.

Objective: to analyze and learn about the reception of Transvestites and Transsexuals in Primary Health Care. Methods: this is an exploratory bibliographic research with a qualitative approach, in which a search was carried out from March to June 2020 in reliable database, in Portuguese, among which Scientifc Electronic Library Online Brazil (SciELO), Google Scholar and the Ministry of Health website can be cited, among other reference periodicals in the area. Results: after detailed analysis of the publications, it was found that 16 publications actually explored the topic in question, being used for the construction of the research. Final Considerations: there is a main method for the reception to be qualified and holistic, which is the training of nurses along with continuing education so that they help change the reality of life for the Trans public in the health field.

Subthalamic Nucleus: Neuroanatomical Review

Discovered in 1865 by Jules Bernard Luys, the subthalamic nucleus is a set of small nuclei located in the diencephalon, inferior to the thalamus and superior to the substantia nigra, that can be visualized in a posterior coronal section. Histologically, it consists of neurons compactly distributed and filled with a large number of blood vessels and sparse myelinated fibers. This review presents an analysis of this anatomical region, considering what is most recent in the literature. Subthalamic neurons are excitatory and use glutamate as the neurotransmitter. In healthy individuals, these neurons are inhibited by nerve cells located in the side globus pallidus. However, if the fibers that make up the afferent circuit are damaged, the neurons become highly excitable, thus causing motor disturbances that can be classified as hyperkinetic, for example ballism and chorea, or hypokinetic, for example Parkinson disease (PD). The advent of deep brain stimulation has given the subthalamic nucleus great visibility. Studies reveal that the stimulation of this nucleus improves themotor symptoms of PD.
