Neutrophil-Lymphocyte Ratio as a Predictor of the Risk of Death in Severe Cases of COVID-19.

BACKGROUND: Identifying clinical characteristics and risk factors, comorbid conditions, and complications arising from SARS-CoV-2 infection is important to predict the progression to more severe forms of the disease among hospitalized individuals to enable timely intervention and to prevent fatal outcomes. The aim of the study is to assess the possible role of the neutrophil/lymphocyte ratio (NLR) as a biomarker of the risk of death in patients with comorbidities hospitalized with COVID-19 in a tertiary hospital in southern Brazil. METHODS: This is a prospective cohort study on patients with SARS-CoV-2 infection admitted to a hospital in the metropolitan region of Porto Alegre from September 2020 to March 2022. RESULTS: The sample consisted of 185 patients with associated comorbidities, namely, hypertension, diabetes mellitus, obesity, cardiovascular, pulmonary, and renal diseases, hospitalized with COVID-19. Of these, 78 died and 107 were discharged alive. The mean age was 66.5 years for the group that died and 60.1 years for the group discharged. Statistical analysis revealed that a difference greater than or equal to 1.55 in the NLR, from hospitalization to the 5th day, was associated with a relative risk of death greater than 2. CONCLUSIONS: Measuring a simple inflammatory marker such as NLR may improve the risk stratification of comorbid patients with COVID-19 and can be considered a useful biomarker.

Post-COVID-19 cognitive symptoms in patients assisted by a teleassistance service: a retrospective cohort study.

Introduction: Four years after the onset of the COVID-19 pandemic, the frequency of long-term post-COVID-19 cognitive symptoms is a matter of concern given the impact it may have on the work and quality of life of affected people. Objective: To evaluate the incidence of post-acute COVID-19 cognitive symptoms, as well as the associated risk factors. Methods: Retrospective cohort, including outpatients with laboratory-confirmed COVID-19 and who were assisted by a public telehealth service provided by the Telehealth Network of Minas Gerais (TNMG), during the acute phase of the disease, between December/2020 and March/2022. Data were collected through a structured questionnaire, applied via phone calls, regarding the persistence of COVID-19 symptoms after 12 weeks of the disease. Cognitive symptoms were defined as any of the following: memory loss, problems concentrating, word finding difficulties, and difficulty thinking clearly. Results: From 630 patients who responded to the questionnaire, 23.7% presented cognitive symptoms at 12 weeks after infection. These patients had a higher median age (33 [IQR 25-46] vs. 30 [IQR 24-42] years-old, p = 0.042) with a higher prevalence in the female sex (80.5% vs. 62.2%, p < 0.001) when compared to those who did not present cognitive symptoms, as well as a lower prevalence of smoking (8.7% vs. 16.2%, p = 0.024). Furthermore, patients with persistent cognitive symptoms were more likely to have been infected during the second wave of COVID-19 rather than the third (31.0% vs. 21.3%, p = 0.014). Patients who needed to seek in-person care during the acute phase of the disease were more likely to report post-acute cognitive symptoms (21.5% vs. 9.3%, p < 0,001). In multivariate logistic regression analysis, cognitive symptoms were associated with female sex (OR 2.24, CI 95% 1.41-3.57), fatigue (OR 2.33, CI 95% 1.19-4.56), depression (OR 5.37, CI 95% 2.19-13.15) and the need for seek in-person care during acute COVID-19 (OR 2.23, CI 95% 1.30-3.81). Conclusion: In this retrospective cohort of patients with mostly mild COVID-19, cognitive symptoms were present in 23.7% of patients with COVID-19 at 12 weeks after infection. Female sex, fatigue, depression and the need to seek in-person care during acute COVID-19 were the risk factors independently associated with this condition.

Myocardial protection: comparing histological effects of single-dose cardioplegic solutions-study protocol for a secondary analysis of the CARDIOPLEGIA trial.

Background: Myocardial protection is crucial for successful cardiac surgery, as it prevents heart muscle damage that can occur during the procedure. Prolonged hypoxia without proper protection can lead to adenosine triphosphate consumption, microvilli loss, blister formation, and edema. Custodiol, del Nido, and modified del Nido are single-dose cardioplegic solutions with proven safety and significance in modern surgery. While each has been independently assessed for patient outcomes, limited research directly compares them. This study aims to compare their myocardial protection using histological analysis. Methods: In a double-blind clinical trial, at least 90 patients will be randomly assigned to receive one of the three cardioplegic solutions. Myocardial biopsies will be collected before cardiopulmonary bypass and 15 minutes after reperfusion. The surgical, anesthetic and perfusion techniques will be the same for all patients, following the Institution's standard protocols. Discussion: The ideal cardioplegic solution does not exist, and its selection remains challenging for surgeons. In modern surgical practice, understanding the behavior of these solutions and the ischemic tissue damage caused during induced cardiac arrest allows for safer surgical procedures. The results of this clinical trial can help in understanding the behavior of cardioplegic solutions and their tissue effects. Thus, by selecting the best cardioplegic solution, ischemic damage can be minimized, enhancing the effectiveness of this essential technique in cardiac procedures. The study may aid in implementing clinical protocols in several institutions, aiming to choose the solution with a superior myocardial protection profile, increasing safety, and reducing expenses.

Clinical characteristics and outcomes in COVID-19 in kidney transplant recipients: a propensity score matched cohort study.

Patients with chronic kidney disease (CKD), especially those on dialysis or who have received a kidney transplant (KT), are considered more vulnerable to severe COVID-19. This susceptibility is attributed to advanced age, a higher frequency of comorbidities, and the chronic immunosuppressed state, which may exacerbate their susceptibility to severe outcomes. Therefore, our study aimed to compare the clinical characteristics and outcomes of COVID-19 in KT patients with those on chronic dialysis and non-CKD patients in a propensity score-matched cohort study. This multicentric retrospective cohort included adult COVID-19 laboratory-confirmed patients admitted from March/2020 to July/2022, from 43 Brazilian hospitals. The primary outcome was in-hospital mortality. Propensity score analysis matched KT recipients with controls - patients on chronic dialysis and those without CKD (within 0.25 standard deviations of the logit of the propensity score) - according to age, sex, number of comorbidities, and admission year. This study included 555 patients: 163 KT, 146 on chronic dialysis, and 249 non-CKD patients (median age 57 years, 55.2% women). With regards to clinical outcomes, chronic dialysis patients had a higher prevalence of acute heart failure, compared to KT recipients, furthermore, both groups presented high in-hospital mortality, 34.0 and 28.1%, for KT and chronic dialysis patients, respectively. When comparing KT and non-CKD patients, the first group had a higher incidence of in-hospital dialysis (26.4% vs. 8.8%, p < 0.001), septic shock (24.1% vs. 12.0%, p = 0.002), and mortality (32.5% vs. 23.3%, p = 0.039), in addition to longer time spent in the intensive care unit (ICU). In this study, chronic dialysis patients presented a higher prevalence of acute heart failure, compared to KT recipients, whereas KT patients had a higher frequency of complications than those without CKD, including septic shock, dialysis during hospitalization, and in-hospital mortality as well as longer time spent in the ICU.

Palliative care and COVID-19: acknowledging past mistakes to forge a better future.

Context: COVID-19 induces complex distress across physical, psychological, and social realms and palliative care (PC) has the potential to mitigate this suffering significantly. Objectives: To describe the clinical characteristics and outcomes of COVID-19 patients with an indication of PC, compared to patients who had no indication, in different pandemic waves. Methods: This retrospective multicenter observational cohort included patients from 40 hospitals, admitted from March 2020 to August 2022. Patients who had an indication of palliative care (PC) described in their medical records were included in the palliative care group (PCG), while those who had no such indication in their medical records were allocated to the non-palliative care group (NPCG). Results: Out of 21,158 patients, only 6.7% had indication for PC registered in their medical records. The PCG was older, had a higher frequency of comorbidities, exhibited higher frailty, and had a higher prevalence of clinical complications and mortality (81.4% vs. 17.7%, p < 0.001), when compared to the NPCG. Regarding artificial life support, the PCG had a higher frequency of dialysis (20.4% vs. 10.1%, p < 0.001), invasive mechanical ventilation (48.2% vs. 26.0%, p < 0.001) and admission to the intensive care unit (53.6% vs. 35.4%, p < 0.001). These differences were consistent across all three waves. Conclusion: A low proportion of patients received PC. Patients in PCG were more fragile, had more clinical complications, and had a higher mortality. On the contrary to our expectations, they received more artificial life support in all three waves. Taken together, these findings suggest that decisions regarding PC indication were made too late, within a context of end-of-life and therapeutic failure.

Lesão Miocárdica e Prognóstico em Pacientes Hospitalizados com COVID-19 no Brasil: Resultados do Registro Nacional de COVID-19 / Myocardial Injury and Prognosis in Hospitalized COVID-19 Patients in Brazil: Results From The Brazilian COVID-19 Registry

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease's pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Equidade e judicialização de medicamentos: perfil das demandas à Secretaria de Saúde do Rio Grande do Sul pelos usuários de Porto Alegre / Equity and judicialization of medicines: profile of the demands made to the Health Secretariat of Rio Grande do Sul by users in Porto Alegre

O provimento de medicamentos por meio de ordens judiciais tem levado a amplas discussões em virtude de sua magnitude e de seu grande impacto na gestão dos recursos públicos. Este trabalho teve como objetivo caracterizar as demandas judiciais para a obtenção de medicamentos e comparar os quartis socioeconômicos na judicialização de medicamentos. Foi realizado um estudo observacional transversal retrospectivo das demandas judiciais por medicamentos ajuizadas por usuários de Porto Alegre contra a Secretaria Estadual de Saúde do Rio Grande do Sul no período de março de 2017 a fevereiro de 2018 e deferidas a favor dos requerentes. Dos processos analisados, 77,5% foram ajuizados pela Defensoria Pública Estadual, porém cerca de 60% foram provenientes de usuários com melhores condições socioeconômicas e mais acesso a informações sobre seus direitos, residindo em áreas com melhores Índices de Desenvolvimento Humano Municipal. Além disso, 72,1% dos usuários possuíam prescrições médicas originadas em serviço privado e misto; e 72,3% dos medicamentos solicitados foram considerados como "fora de lista". Os dados revelaram que a judicialização pode contrariar o princípio da equidade previsto nas políticas públicas de saúde relacionadas à assistência farmacêutica. A criação de uma Comissão de Farmácia e Terapêutica Estadual e o emprego da avaliação de tecnologias em saúde podem subsidiar as decisões judiciais e auxiliar na elaboração de pareceres técnicos e protocolos clínicos.

The provision of medicines through court orders has led to wide discussions due to its magnitude and its great impact on the management of public resources. The objective of this study was to characterize the judicial demands for obtaining medicines and to compare the socioeconomic quartiles in the judicialization of medicines. A retrospective cross-sectional observational study of judicial demands for medications filed by users in Porto Alegre against the State Health Secretariat of Rio Grande do Sul from March 2017 to February 2018 and granted in favor of the claimants was carried out. Of the cases analyzed, 77.5% were filed by the State Public Defender's Office, but around 60% were from users with better socioeconomic conditions and more access to information about their rights, residing in areas with better Municipal Human Development Indexes. In addition, 72.1% of the users had medical prescriptions originated from private and mixed services; and 72.3% of the requested medications were considered as "off the list". The data revealed that judicialization may contradict the principle of equity foreseen in public health policies related to pharmaceutical care. The creation of a State Pharmacy and Therapeutics Committee and the use of health technology assessment could subsidize court decisions and assist in the elaboration of technical opinions and clinical protocols.

Adesão ao tratamento com psicofármacos: fatores de proteção e motivos de não adesão ao tratamento farmacológico / Adherence to psychotropic treatment: protection factors and reasons for non adherence to pharmacologic treatment

A não adesão ao tratamento farmacológico de pacientes com agravos comuns de saúde mental traz grande comprometimento da qualidade de vida do paciente, além de influenciar em outros fragmentos importantes da vida. Intervenções na adesão ao tratamento por profissionais da atenção primária, além de custo-efetivas, reduzem a morbidade, melhoram a qualidade de vida e fortalecem o vínculo do paciente com a atenção primária. Este estudo tem como objetivo buscar as barreiras e os motivos para a adesão medicamentosa. Foram selecionados seis pacientes pertencentes à área de uma unidade de saúde, com uso de psicofármacos, e realizada entrevista para investigação de motivos de barreira e proteção ao uso desses medicamentos. Os motivos de não adesão referidos foram os efeitos adversos, a vontade de não depender do medicamento e a precária comunicação com o prescritor. Como fatores de adesão, a motivação pelo resultado, a confiança no prescritor, uma boa comunicação com o prescritor e a família. Sendo assim, percebe-se a necessidade de uma boa relação dos profissionais de saúde com os usuários, por meio da comunicação, vínculo e educação em saúde.

Non-adherence to pharmacological treatment of patients with common mental health illnesses brings great prejudice to the patient´s quality of life of as well as influencing other important fragments of life. Interventions in treatment adherence for primary care professionals not only are cost effective but also reduce morbidity, improve quality of life and strengthen the bond with the primary health care services. This study aims to search the barriers and protective factors for to medication adherence. Six patients belonging to the area of a health care facility and with current use of psychotropic drugs were selected for a interview in order to investigate barriers and protective factors to the use of these medications. The reasons for non adherence brought by the interviewee were adverse effects, willing not to depend on medication and poor communication with the prescriber. As for the protective factors were indentified motivation by the results, family, confidence in the prescriber and good communication with the prescriber. Thus, we see the need for a good relationship of health professionals with users, through a good communication, bond and health education.

O fortalecimento da Atenção Primária à Saúde nos municípios da Região Metropolitana de Porto Alegre, Brasil, após a inserção no Programa Mais Médicos: uma comparação intermunicipal / Strengthening Primary Health Care in the municipalities in the Metropolitan Region of Porto Alegre, Brazil, after the introduction of the Mais Médicos (More Doctors) Program: an inter-municipal comparison

Resumo Este artigo visa propor uma adaptação da metodologia utilizada por Starfield e Shy (2002) para avaliar a qualidade da atenção primária em saúde (APS) dos municípios que aderiram ao Programa Mais Médicos. Os indicadores foram adaptados para cada um dos nove critérios propostos na metodologia original e aplicados para os municípios de médio e grande porte da Região Metropolitana de Porto Alegre, antes e depois destes integrarem o Programa Mais Médicos. Em 2014, os municípios foram agregados em três grupos, conforme seus escores. As análises de correlações entre diferentes grupos de escores dos municípios e os indicadores de saúde avaliados não se mostraram significativas, porém, as médias dos indicadores avaliados são melhores no grupo de municípios caracterizados com os melhores escores da APS. Em relação aos indicadores de renda, os maiores gastos per capita em saúde estão relacionados à melhor performance da APS nesses municípios. A adaptação desta metodologia pode indicar melhor compreensão das políticas relacionadas à determinação da saúde.

Abstract This article aims to propose an adaptation of the methodology used by Starfield and Shy (2002) to assess the quality of health care in the municipalities which joined the Mais Médicos (More Doctors) Program. The indicators were adapted for each one of the nine criteria proposed in the methodology and were applied to medium and large municipalities in the Metropolitan Region of Porto Alegre before and after they were integrated in the Mais Médicos Program. In 2014, the municipalities were grouped into three groups according to their scores. An analysis concerning any correlations between the different group scores for the municipalities and the health indicators that were evaluated, did not reveal anything significant. However the averages of the evaluated indicators were better in the group of municipalities characterized through having the best APS scores. In relation to the income indicator, the highest amount of money spent per capita in health is related to the best APS performance in the municipalities. An adaption of this methodology may be able to provide a better understanding of the policies related to health care.

Tendências na utilizaçäo de antimicrobianos em um hospital universitário, 1990-1996 / Trends in antimicrobial utilization in a university hospital, 1990-1996

OBJETIVO: Uma das principais preocupaçöes mundiais quanto ao uso de medicamentos está relacionada à utilizaçäo de antimicrobianos. Nos países em desenvolvimento, poucos recursos säo empregados na monitorizaçäo de açöes sobre o uso racional de medicamentos. Säo, também, limitados os dados sobre o uso daqueles agentes em hospitais. Assim realizou-se estudo para determinar os padröes de uso de antimicrobianos em hospital num período de sete anos (1990 a 1996). MÉTODOS: O estudo foi realizado em um hospital universitário, terciário, com 690 leitos, localizado em Porto Alegre, RS. Os registros hospitalares foram revisados visando identificar o consumo de antimicrobianos por pacientes internados, sendo os resultados expressos em dose diária definida (DDD) por 100 leitos-dia. A análise de conglomerados foi realizada para determinar as tendências de consumo dos agentes individuais. RESULTADOS: O consumo de antimicrobianos aumentou com o correr dos anos, passando de 83,8 DDD por 100 leitos-dia, em 1990, a 124,58 DDD por 100 leitos-dia em 1996. O grupo de medicamentos mais utilizado foi de penicilinas (39,6 por cento), seguido por cefalosporinas (15,0 por cento), aminoglicosídeos (14,4 por cento), sulfonamidas (12,8 por cento), glicopeptídeos (3,6 por cento) e lincosaminas (3,1 por cento). Estes grupos foram responsáveis por cerca de 90 por cento do consumo. A análise de conglomerados do uso de antimicrobianos mostrou 13 grupos principais de tendência de consumo. CONCLUSOES: O consumo de antimicrobianos cresceu no período avaliado, sendo expressivamente mais alto em comparaçäo com o relatado em outros estudos. Quando novas alternativas terapêuticas foram disponibilizadas no hospital, o uso de medicamentos antigos decresceu e, em alguns casos, existiu manutençäo dos níveis de consumo. Quando foi realizada intervençäo específica como uma campanha para o uso correto de cefoxitina, as mudanças esperadas ocorreram
