Abstract: En | Text: En | PDF: En

Abstract Tea is identified as the second most consumed drink in the world, and its frequent intake is related to several benefits to human health, considering its antimutagenic, anticarcinogenic, antimicrobial, anti-inflammatory, antihistamine, diuretic, calming, and above all, antioxidant effects. These effects are often associated with the action of the phenolic compounds contained in these infusions. In Brazil, among the most consumed infusions are the teas of chamomile (Matricaria chamomilla L.), lemongrass (Cymbopogon citratus (D.C.) Stapf), lemon balm (Melissa officinalis L.), anise (Pimpinella anisum L.), yerba mate (Ilex paraguariensis A. St.-Hil), peppermint (Mentha piperita L.), and green/black tea (Camellia sinensis L.). Therefore, said popularity is the reason why the mentioned species were chosen to be evaluated on inflammatory enzymes. The activity of phospholipases A2 was reduced by more than 25% after treatment with black tea and yerba mate. The most significant inhibition of protease activity was observed after incubation with black tea (40.74%), green tea (31.48%) and yerba mate (25.93%). Infusions of black and green tea reduced hemolysis in semisolid and liquid media, and for the latter, reductions of up to 50% of hemolytic activity were observed, indicating an anti-inflammatory potential of the samples. Plasma incubations with green tea, black tea and lemon balm and subsequent addition of venom (1:10 ratio; tea:PBS, v:v) prolonged the coagulation time of citrated plasma by approximately twice compared to the positive control. All controls with pure tea had a thrombolytic character, in higher proportions than the venom control, especially chamomile (273.55% dissolution). Phenolic compounds derived from phenolic acids, flavonoids, and tannins are identified as the main agents that promote the biological effects observed in this study. This is mainly due to their anti-catalytic properties exerted on inflammatory enzymes and as chelating agents of enzymatic co-factors. The evaluated teas showed potential for nutraceutical use, thus pointing to the possibility of use as an adjuvant in the treatment of diseases linked to hemostasis.

Abstract Objective: to analyze the factors related to sleep disorders reported by Nursing professionals during the COVID-19 pandemic. Method: this is a cross-sectional and analytical study conducted with Nursing professionals from all Brazilian regions. Sociodemographic data, working conditions and questions about sleep disorders were collected. The Poisson regression model with repeated measures was used to estimate the Relative Risk. Results: 572 answers were analyzed, which revealed that non-ideal sleep duration, poor sleep quality and dreams about the work environment were predominant during the pandemic, with 75.2%, 67.1% and 66.8% respectively; as well as complaints of difficulty sleeping, daytime sleepiness and non-restorative sleep during the pandemic were reported by 523 (91.4%), 440 (76.9%) and 419 (73.2%) of the Nursing professionals, respectively. The relative risk of having such sleep disorders during the pandemic was significant for all variables and categories studied. Conclusion: non-ideal sleep duration, poor sleep quality, dreams about the work environment, complaints regarding difficulty sleeping, daytime sleepiness and non-restorative sleep were the predominant sleep disorders among Nursing professionals during the pandemic. Such findings point to possible consequences on health, as well as on the quality of the work performed.

Abstract BACKGROUND: Severe acute respiratory syndrome coronavirus 2 has several mechanisms of action related to inflammatory responses, especially in individuals diagnosed with obesity. This hyperinflammatory clinical profile resulting from the association between obesity and coronavirus disease 2019 (COVID-19) may be attenuated by regular physical activity. OBJECTIVE: The aim of this study was to review the evidence on the consequences of physical inactivity and physical activity on COVID-19 in patients with obesity. DESIGN AND SETTING: Narrative review at the Bahiana School of Medicine and Public Health in Salvador, Brazil. METHODS: We searched evidence on the association of COVID-19 with physical activity and obesity using the following keywords: “covid-19,” “physical activity,” and “obesity”. The databases used were MEDLINE (PubMed), ScienceDirect, and Virtual Health Library. Studies published from 2019 to 2021 and available in Portuguese, English, and Spanish were included. The final search was conducted on September 26, 2021. RESULTS: We identified 661 studies in the database, among which 71 were considered for inclusion in the narrative review of the molecular aspects of COVID-19 and its relationship with physical activity and obesity. CONCLUSION: This literature review enabled the perception of the relationship between the molecular mechanisms of COVID-19 and obesity. Regular physical activity had various benefits for the inflammatory condition of the studied population, highlighting moderate-intensity.

ABSTRACT Introduction: Bisphosphonates have an inhibitory impact on osteoclastic activity, reducing bone resorption. However, the influence of risedronate on tooth movement is not well-defined. Objective: This systematic review assessed the effect of risedronate intake on orthodontic tooth movement. A case report was also provided. Methods: Two independent reviewers searched six databases (PubMed, Web of Science, Ovid, Lilacs, Scopus, and Open Grey). The searches were carried out in April/2020, and an update was set in place in June/2023. Therefore, the searches considered a timeline from the databases’ inception date until June/2023, with no publication date and/or language restrictions. The clinical question focused on evaluating the orthodontic tooth movement and relapse movement (Outcome) in animals (Population) exposed to risedronate (Exposure), compared to control groups (Comparison). The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines were applied, and the protocol was registered in PROSPERO (CRD42020168581). The risk of bias was determined using the Systematic Review Centre for Laboratory Animal Experimentation protocol (SYRCLE). Results: Two studies in rats and one in guinea pigs were included in the systematic review. The studies reported a decrease in orthodontic tooth movement, a reduction in the relapse movement, and a reduced number of positive tartrate-resistant acid phosphatase (TRAP) cells, with a significantly reduced number of bone gaps after the administration of risedronate in rats. A case report illustrated the effects of risedronate administration in one patient. Conclusion: Based on the systematic review, risedronate seems to impair orthodontic tooth movement and relapse due to a decrease in bone resorption cells.

RESUMO Introdução: Os bifosfonatos têm um impacto inibitório na atividade osteoclástica, reduzindo a reabsorção óssea. No entanto, a influência do risedronato no movimento dentário não está bem definida. Objetivo: Esta revisão sistemática avaliou o efeito do uso de risedronato no movimento ortodôntico dos dentes. Um relato de caso também é apresentado. Métodos: Dois revisores independentes pesquisaram seis bases de dados (PubMed, Web of Science, Ovid, Lilacs, Scopus e Open Grey), considerando o período de abril de 2020 até junho de 2023, sem restrições de data e/ou idioma de publicação. A questão clínica focou em avaliar o movimento ortodôntico dos dentes e movimento de recidiva (resultado) em animais (população) expostos ao risedronato (exposição) em comparação com grupos de controle (comparação). Foram aplicadas as Diretrizes Preferenciais para Revisão Sistemática e Metanálise (PRISMA) e um protocolo foi registrado no PROSPERO (CRD42020168581). O risco de viés foi determinado utilizando o protocolo do Centro de Revisão Sistemática para Experimentação em Animais de Laboratório (SYRCLE). Resultados: Dois estudos em ratos e um em porquinhos-da-índia foram incluídos na revisão sistemática. Os estudos relataram uma diminuição no movimento ortodôntico dos dentes, uma redução no movimento de recidiva e um número reduzido de células positivas à fosfatase ácida tartarato-resistente (TRAP) com um número significativamente reduzido de falhas ósseas após a administração de risedronato em ratos. Um relato de caso ilustrou os efeitos da administração de risedronato em uma paciente. Conclusão: Com base na revisão sistemática, o risedronato parece interferir no movimento ortodôntico dos dentes e na recidiva devido a uma diminuição nas células de reabsorção óssea.

ABSTRACT Objective: To analyze the association between time of arrival at a reference hospital and mortality of people with ischemic stroke. Method: Descriptive and inferential statistics were used. Modifying and confounding variables between time of arrival and mortality were observed in the multivariate analysis. The Akaike Information Criterion was used to choose the model. Statistical significance of 5% and risk correction using the Poisson Model were adopted. Results: Most participants arrived within 4.5 hours of symptom onset or wake up stroke to the referral hospital and 19.4% died. The score of the National Institute of Health Stroke Scale was a modifier. In the multivariate model stratified by scale score ≥14, arrival time >4.5h was associated with lower mortality; and age ≥60 years and having Atrial Fibrillation, to higher mortality. In the model stratified by score ≤13, previous Rankin ≥3, and presence of atrial fibrillation were predictors of mortality. Conclusion: The relationship between time of arrival and mortality up to 90 days was modified by the National Institute of Health Stroke Scale. Prior Rankin ≥3, atrial fibrillation, time to arrival ≤4.5h, and age ≥60 years contributed to higher mortality.

RESUMEN Objetivo: Analizar la asociación entre el tiempo de llegada a un hospital de referencia y la mortalidad de las personas con accidente cerebrovascular isquémico. Método: Fueron usadas estadísticas descriptivas e inferenciales. En el análisis multivariado se verificaron variables modificadoras y confusoras entre el tiempo de llegada y la mortalidad. Para la elección del modelo se utilizó el Criterio de Información de Akaike. Se adoptó la significación estadística del 5% y la corrección del riesgo mediante el Modelo de Poisson. Resultados: La mayoría de los participantes llegaron dentro de las 4,5 horas posteriores al inicio de los síntomas o wake up stroke al hospital de referencia y el 19,4% fallecieron. La puntuación de la escala National Institute of Health Stroke Scale fue un modificador. En el modelo multivariante estratificado por puntaje de escala ≥14, el tiempo de llegada >4,5 h se asoció con una menor mortalidad; y edad ≥60 años y con Fibrilación Auricular a mayor mortalidad. En el modelo estratificado por puntaje ≤13, Rankin previo ≥3 y tener fibrilación auricular fueron predictores de mortalidad. Conclusión: La relación entre tiempo de llegada y mortalidad hasta los 90 días fue modificada por puntaje de la escala National Institute of Health Stroke Scale. Rankin previo ≥3, fibrilación auricular, tiempo hasta la llegada ≤4,5 h y la edad ≥60 años contribuyeron a una mayor mortalidad.

ABSTRACT Objective To analyze the karyotype test and myeloid panel with next-generation sequencing findings in patients with myelofibrosis, and to compare transplant characteristics in patients referred for bone marrow transplantation. Methods Retrospective, single-center study with patients diagnosed with myelofibrosis treated at Hospital Israelita Albert Einstein between 2010 and 2020. Results A total of 104 patients with myelofibrosis were examined. Patients who had not been submitted to tests in our service were excluded. The final sample comprised 69 patients. Of these 69, 56 were submitted to karyotyping and 22 to myeloid panel with next-generation sequencing. Karyotype was normal in 60% of the patients and altered in 40%. The prevalence of high-risk molecular mutations was higher in patients referred for bone marrow transplantation (100% versus 50%). The median follow-up of transplant patients was 2.4 years and the overall survival at 2 years was 80% (95%CI: 62-100%). Conclusion The molecular analysis enables estimating the patient’s risk and thus instituting more aggressive treatment such as bone marrow transplant for patients at higher risk, being a relevant tool to guide therapy. Given the significance of molecular analysis for therapeutic decision-making in myelofibrosis, collection and disclosure of data on the prevalence of cytogenetic changes and findings of next-generation sequencing in affected patients is important.

Abstract The University Pharmacy Program (FU), from the Federal University of Rio de Janeiro (UFRJ), was created based on the need to offer a curricular internship to students of the Undergraduate Course at the Faculty of Pharmacy. Currently, it is responsible for the care of about 200 patients/day, offering vacancies for curricular internships for students in the Pharmacy course, it has become a reference in the manipulation of many drugs neglected by the pharmaceutical industry and provides access to medicines for low-income users playing an important social function. Research is one of the pillars of FU-UFRJ and several master and doctoral students use the FU research laboratory in the development of dissertations and theses. As of 2002, the Pharmaceutical Care extension projects started to guarantee a rational and safe pharmacotherapy for the medicine users. From its beginning in 1982 until the current quarantine due to the COVID-19 pandemic, FU-UFRJ has been adapting to the new reality and continued to provide patient care services, maintaining its teaching, research, and extension activities. The FU plays a relevant social role in guaranteeing the low-income population access to special and neglected medicines, and to pharmaceutical and education services in health promotion.

Abstract Objectives: this study aimed to explore a set of factors associated with lower maternal-fetal attachment (MFA) in pregnant women. Methods: this is a cross-sectional study corresponding to the second wave of a cohort study with a population-based sample of pregnant women in the South of Brazil. The maternal-fetal attachment scale (MFAS) was used to measure MFA. Bivariate analysis was performed using the t-test and ANOVA. The variables that presented p<0.20 were taken for multivariate analysis, through linear regression, in order to control possible confounding factors. Results: a total of 840 pregnant women were included. Pregnant women who had lower MFA means were those who did not live with a partner (B=-3.8 [CI95%=-6.0; -1.7]), those between the first and second trimester of pregnancy (B=-4.3 [CI95%=-5.9; -2.6]), those who did not have support from their mother during pregnancy (B=-2.4 [CI95%=-4.6; -0.2]), and those with depressive symptoms (B=-4.9 [CI95%=-7.4; -2.5]). Conclusions: the results showed that a higher MFA it is associated with an adequate support network during pregnancy, better maternal mental health, and with an advanced pregnancy. Early evaluation of MFA and effort to promote an adequate prenatal bond, focusing on maternal psychological and emotional aspects are strongly suggested.

Resumo Objetivos: explorar um conjunto de fatores associados ao menor apego materno-fetal (AMF) em gestantes. Métodos: trata-se de um estudo transversal, correspondente à segunda fase de um estudo de coorte com uma amostra de base populacional de gestantes no sul do Brasil. Foi utilizada a Escala de Apego Materno-Fetal (EAMF) para medir o AMF. A análise bivariada foi realizada através do teste t e ANOVA. As variáveis que apresentaram p<0,20 foram levadas para análise multivariada, por meio de regressão linear, a fim de controlar possíveis fatores de confusão. Resultados: foram incluídas 840 gestantes. As gestantes que apresentaram menores médias de AMF foram aquelas que não moravam com um companheiro (B=-3,8 [IC95%=-6,0; -1,7]), que estavam entre o primeiro e o segundo trimestre de gestação (B=-4,3 [IC95%=-5,9; -2,6]), que não tiveram o apoio da mãe durante a gestação (B=-2,4 [IC95%=-4,6; -0,2]) e que apresentaram sintomas depressivos (B=-4,9 [IC95%=-7,4; -2,5]). Conclusões: os resultados mostraram que um maior AMF está associado a presença de uma rede de apoio adequada na gravidez, melhor saúde mental materna e a uma gestação avançada. A avaliação precoce do AMF e a promoção de um vínculo pré-natal adequado, com foco nos aspectos psicológicos e emocionais maternos são fortemente sugeridos.

Abstract Background Implementing stroke care protocols has intended to provide better care quality, favor early functional recovery, and achieving long-term results for the rehabilitation of the patient. Objective To analyze the effect of implementing care protocols on the outcomes of acute ischemic stroke. Methods Primary studies published from 2011 to 2020 and which met the following criteria were included: population should be people with acute ischemic stroke; studies should present results on the outcomes of using protocols in the therapeutic approach to acute ischemic stroke. The bibliographic search was carried out in June 2020 in 7 databases. The article selection was conducted by two independent reviewers and the results were narratively synthesized. Results A total of 11,226 publications were retrieved in the databases, of which 30 were included in the study. After implementing the protocol, 70.8% of the publications found an increase in the rate of performing reperfusion therapy, such as thrombolysis and thrombectomy; 45.5% identified an improvement in the clinical prognosis of the patient; and 25.0% of the studies identified a decrease in the length of hospital stay. Out of 19 studies that addressed the rate of symptomatic intracranial hemorrhage, 2 (10.5%) identified a decrease. A decrease in mortality was mentioned in 3 (25.0%) articles out of 12 that evaluated this outcome. Conclusions We have identified the importance of implementing protocols in increasing the performance of reperfusion therapies, and a good functional outcome with improved prognosis after discharge. However, there is still a need to invest in reducing post-thrombolysis complications and mortality.

Resumo Antecedentes A implementação de protocolos de acidente vascular cerebral (AVC) visa proporcionar uma melhor qualidade da assistência, favorecer a recuperação funcional precoce e alcançar resultados para a reabilitação do paciente. Objetivo Analisar o efeito da implantação de protocolos nos desfechos do AVC isquêmico agudo. Métodos Foram incluídos estudos primários publicados entre 2011 e 2020 e que atendiam aos seguintes critérios: população deveria ser constituída de pessoas com AVC isquêmico agudo; apresentar resultados sobre os desfechos do uso de protocolos na abordagem terapêutica ao AVC isquêmico agudo. A busca bibliográfica foi realizada em junho de 2020 em 7 bases de dados. A seleção dos artigos foi feita por dois revisores independentes e a síntese dos resultados foi feita de forma narrativa. Resultados Foram recuperadas 11.226 publicações, das quais 30 foram incluídas no estudo. Após a implementação do protocolo, 70,8% das publicações constataram aumento na taxa de realização de terapia de reperfusão, como a trombólise e a trombectomia; 45,5% identificaram melhora no prognóstico clínico do paciente; e 25,0% dos estudos identificaram diminuição no tempo de internação hospitalar. De 19 estudos que abordaram a taxa de hemorragia intracraniana sintomática, 2 (10,5%) identificaram diminuição nesta taxa. A diminuição da mortalidade foi citada em 3 (25,0%) artigos de 12 que avaliaram tal desfecho. Conclusões Identificou-se a importância da implantação de protocolos no aumento da realização das terapias de reperfusão, e ao bom desfecho funcional com melhora do prognóstico após a alta. No entanto, ainda há que se investir na diminuição das complicações pós trombólise e da mortalidade.

ABSTRACT BACKGROUND: Stroke is a major cause of death and functional disability worldwide. Knowledge of the associated factors is essential for defining education, management, and healthcare strategies. OBJECTIVE: To analyze the association between arrival time at a neurology referral hospital (ATRH) and functional disability in patients with ischemic stroke 90 days after the event. DESIGN AND SETTING: Prospective cohort study conducted at a public institution of higher education in Brazil. METHODS: This study included 241 people aged ≥ 18 years who presented ischemic stroke. The exclusion criteria were death, inability to communicate without companions who could answer the research questions, and > 10 days since ictus. Disability was assessed using the Rankin score (mR). Variables for which associations showed a P value ≤ 0.20 in bivariate analysis were tested as modifiers between ATRH and disability. Significant interaction terms were used for multivariate analysis. Multivariate logistic regression analysis was performed with all variables, arriving at the complete model and adjusted beta measures. The confounding variables were included in the robust logistic regression model, and Akaike’s Information Criterion was adopted to choose the final model. The Poisson model assumes a statistical significance of 5% and risk correction. RESULTS: Most participants (56.0%) arrived at the hospital within 4.5 hours of symptom onset, and 51.7% presented with mRs of 3 to 5 after 90 days of ictus. In the multivariate model, ATRH ≥ 4.5 hours and females were associated with more significant disability. CONCLUSIONS: Arrival at the referral hospital 4.5 hours after the onset of symptoms or wake-up stroke was an independent predictor of a high degree of functional disability.

Abstract Hydrogels are used for wound treatment, as they may contain one or more active components and protect the wound bed. Papain is one of the active substances that have been used with this purpose, alongside urea. In this paper, carboxypolymethylene hydrogels containing papain (2% and 10% concentrations) and urea (5% concentration) were produced. Physical-chemical stability was performed at 0, 7, 15 and 30 days at 2-8ºC, 25ºC and 40ºC, as well as the rheological aspects and proteolytic activity of papain by gel electrophoresis. Clinical efficacy of the formulations in patients with lower limb ulcers was also evaluated in a prospective, single-center, randomized, double-blind and comparative clinical trial. The results showed 7-day stability for the formulations under 25ºC, in addition to approximately 100% and 15% of protein activity for 10% and 2% papain hydrogel, respectively. The rheological profile was non-Newtonian for the 10% papain hydrogel tested. There were no significant differences regarding the mean time for healing of the lesions, although 10% papain presented a better approach to be used in all types of tissue present in the wound bed.

Abstract Background Systemic arterial hypertension (SAH) is a multifactorial disease, highly prevalent and associated with health risks. Objective The purpose of this study was to investigate the association between SAH and laboratory, anthropometric, heart rate variability (HRV), and obstructive sleep apnea markers and, secondarily, to analyze the sensitivity and specificity of the variables that are independent factors in the association. Methods Cross-sectional study with 95 obese patients treated at an obesity referral clinic in Salvador, BA, Brazil. SAH data were obtained from electronic medical records. The sample was stratified in the Normotensive Group (NG) and the Hypertensive Group (HG), and laboratory markers, body composition, polysomnography, and HRV were measured to evaluate the association of SAH with the predictor variables. For the analysis, p<0.05 was adopted. Results The average age of the NG was 36.3 ± 10.1 and HG 40.4 ± 10.6 years; 73.7% were women in the NG and 57.9% in HG; 82.4% in HG had insulin resistance. In the multivarious logistics regression model with adjustments in age, sex, height, and oxyhemoglobin saturation, SAH was inversely associated with fasting plasma glucose mg/dL (odds ratio [OR] = 0.96; 95% confidence interval [CI] = 0.92-0.99) and visceral fat area (VFA) cm2(OR = 0.98; 95% CI = 0.97-0.99). The area under the VFA curve was 0.728; CI 95% (0.620-0.836); fasting plasma glucose 0.693;CI 95% (0.582-0.804). Conclusions Lower VFA and fasting plasma glucose concentrations were inversely associated with SAH. In addition, fasting plasma glucose and VFA showed a high sensitivity for SAH screening.

Resumo Fundamento A hipertensão arterial sistêmica (HAS) é uma doença multifatorial, altamente prevalente e associada a riscos à saúde. Objetivo O objetivo deste estudo foi investigar a associação entre HAS e marcadores laboratoriais, antropométricos, de variabilidade da frequência cardíaca (VFC) e de apneia obstrutiva do sono e, em segundo plano, analisar a sensibilidade e especificidade das variáveis que são fatores independentes na associação. Métodos Estudo transversal com 95 pacientes obesos atendidos em um ambulatório de referência em obesidade em Salvador, BA, Brasil. Os dados da HAS foram obtidos dos prontuários eletrônicos. A amostra foi estratificada em Grupo Normotenso (GN) e Grupo Hipertenso (GH), sendo medidos marcadores laboratoriais, composição corporal, polissonografia e VFC para avaliar a associação da HAS com as variáveis preditoras. Para as análises, adotou-se p<0,05. Resultados A média da idade do GN foi de 36,3 ± 10,1 e GH 40,4 ± 10,6 anos, 73,7% eram mulheres no GN e 57,9% no GH; 82,4% no GH apresentavam resistência à insulina. No modelo de regressão logística multivariado com ajustes para idade, sexo, altura e saturação de oxi-hemoglobina, a HAS foi inversamente associada à glicose plasmática em jejum mg/dL (odds ratio [OR] = 0,96; intervalo de confiança de 95% [IC] = 0,92-0,99) e área de gordura visceral (AGV) cm2 (OR = 0,98; IC 95% = 0,97-0,99). A área sob a curva AGV foi de 0,728; IC 95% (0,620-0,836) e glicemia de jejum 0,693; IC 95% (0,582-0,804). Conclusão Menores concentrações de AGV e glicemia de jejum foram inversamente associadas à HAS. Além disso, tanto a glicemia de jejum quanto o AGV mostraram alta sensibilidade para triagem de HAS.

ABSTRACT Objective: To verify the association between sociodemographic, clinical, environmental, cognitive, and emotional factors and the decision time of people with ischemic stroke to seek a health service after the onset of symptoms or wake up stroke. Method: Cross-sectional study carried out from March to October 2019, with 304 patients, in a public hospital, a reference in neurology. Data obtained through interview and from medical records. Decision time was analyzed as a geometric mean. In the bivariate and multivariate analyses, linear regression was used and the Akaike Information Criterion was used to select the best model. Statistical significance of 5% was adopted. Results: The geometric mean of decision time was 0.30h (95% CI 0.23–0.39). The final model explained this time in 41%, showing an increase of 0.5 min for people with arterial hypertension; 10.8 min for those who waited for symptoms to improve; 1.4 min for those who were alone at the onset of symptoms; 3.9 min for those at home; 3.2 min for the ones at work; and 2.1 for those on the street/public space. Conclusion: The mean decision time for seeking a health service was high and influenced by clinical, environmental, cognitive, and emotional variables. The results guide nurses regarding health education.

Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

Abstract The objective of this paper was to develop and evaluate two semi-solid pharmaceutical forms containing 0.1% tacrolimus: cream (CRT01) and gel (GLT01). For the evaluation of physicochemical stability, at times 0, 30, 60 and 90 days, at 23°C and at 40°C, High Performance Liquid Chromatography coupled with a Diode Array Detector (HPLC-DAD) was employed. This method was developed and validated for tacrolimus quantification. The occlusivity test and skin permeation assay were also performed, using an animal model (Wistar rats), and the CRT01 and GLT01 were compared to the 0.1% tacrolimus ointment (PFU01) obtained from the University Pharmacy, Federal University of Rio de Janeiro, Brazil. CRT01 and GLT01 presented a homogeneous aspect and consistency adequate for topical products, along with sensory characteristics above PFU01. They also presented adequate physicochemical stability for 90 days and a lower occlusive effect than PFU01 (p<0.05). CRT01 showed greater affinity for the skin when compared to PFU01 and GLT01, with low systemic absorption. The CRT01 semi-solid formulation was considered the most adequate one to treat patients with atopic dermatitis or other dermatologic inflammatory diseases, promoting rational use of tacrolimus.
