Comparação da qualidade de vida de portadores de câncer de pulmão antes e após o tratamento quimioterápico

OBJECTIVE: this prospective study aimed to assess the quality of life related to health (QLRH) of patients with lung cancer after chemotherapy treatment. METHOD: The QLRH was assessed using the questionnaires Quality-of-Life Questionnaire-Core 30 (QLQ-C30) and Lung Cancer Module (LC13), version 3.0. RESULTS: the sample was made up of 11 women and 19 men, with an average age of 68 years (51-87 years). After the chemotherapy treatment, the authors observed a clinically-relevant improvement in general quality of life, as well as in the symptoms of dyspnea, insomnia, hemoptysis, cough, thoracic pain, pain in the arm/shoulder, and financial difficulty. There was a worsening on the functional scale which assesses role performance and symptoms of fatigue, nausea and vomiting, sensory neuropathy, pain in other parts, constipation, loss of appetite and alopecia. CONCLUSION: although the patients have an improvement of their QLRH and symptoms related to the lung cancer after the chemotherapy treatment, there was a worsening of the symptoms which resulted from the toxicity of the chemotherapy medications.OBJETIVO: estudio prospectivo con objetivo de evaluar la calidad de vida relacionada a la salud (CVRS) de pacientes con cáncer de pulmón después de tratamiento de quimioterapia.

Qualidade de vida e sobrecarga dos cuidadores de portadores de Doença Pulmonar Obstrutiva Crônica em oxigenoterapia

OBJECTIVE: to assess the quality of life and burden of caregivers to Chronic Obstructive Pulmonary Disease patients on Long-Term Oxygen Therapy and to investigate the factors influencing this burden. METHOD: this is an analytical, cross-sectional study of 80 persons with Chronic Obstructive Pulmonary Disease on Long-Term Oxygen Therapy who used the specialized outpatient center of the Federal University of São Paulo, and their carers. The following instruments were used: Medical Outcomes Studies 36 (SF-36), Caregiver Burden Scale (CBS) and the Katz Index, along with socio-demographic and clinical variables. RESULTS: the most compromised scores on the carers' quality of life questionnaire were for Vitality and Mental Health. On the Caregiver Burden Scale, the domain which created the greatest burden for carers was the Environment. With the exception of Emotional Involvement, all the domains of quality of life were affected negatively by the domains of caregiver burden. CONCLUSION: it was shown that carers' quality of life was compromised and that they were overburdened with care tasks, confirming that assisting persons with Chronic Obstructive Pulmonary Disease is an important element in carers' quality of life.OBJETIVO: evaluar la calidad de vida y la sobrecarga de cuidados experimentada por cuidadores de portadores de la Enfermedad Pulmonar Obstructiva Crónica en uso de Oxigenoterapia Domiciliar Prolongada e investigar los factores que influencian esa sobrecarga.

Diabetes-related symptoms, acute complications and management of diabetes mellitus of patients who are receiving palliative care: A protocol for a systematic review

Introduction: Worldwide, an estimated 40 million people are in need of palliative care each year, but only 14% receive it. The incidence of diabetes mellitus (DM) in patients receiving palliative care is higher than in the general population. This association is intended to grow as a result of the rising burden of DM worldwide, ageing populations and the improved overall survival time of several diseases over the last few decades. Recommendations for DM management in the context of palliative care are mainly based on expert opinion as there is a lack of suitable evidence base and randomised clinical trials in palliative care are scarce. The aim of our systematic review is to identify the best DM management practices in order to reduce important DM-related symptoms and acute complications in patients receiving palliative care. Methods and analysis: The authors will study the DM treatment and management literature, surveying the different approaches employed to treat adult palliative patients. Core health bibliographic databases will be searched from January 1990 to May 2019. Data sources will include Ovid MEDLINE, Embase, PubMed, Web of Sciences, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Scopus, Cumulative Index to Nursing and Allied Health Literature and grey literature. Details regarding diet, oral and injectable glucose-lowering medicines, insulin regimens and blood glucose monitoring strategies will be evaluated. We defined the primary outcomes to compare between DM management approaches as the presence of symptoms (polyuria, polydipsia and polyphagia) and acute complications of DM (hypoglycaemia, hyperglycaemic hyperosmolar state and diabetic ketoacidosis), and secondary outcomes as hospital admissions and deaths due to DM-related complications, health-related quality of life and glycaemic control. Ethics and dissemination: The systematic review methodology does not require ethics approval due to the nature of the study design. The results of the systematic review will be published in a peer-reviewed journal and will be publicly available

Influence that sociodemographic variables, clinical characteristics, and level of dependence have on quality of life in COPD patients on long-term home oxygen therapy

OBJECTIVE: To evaluate and correlate the quality of life (QoL) of COPD patients on long-term home oxygen therapy (LTOT) with their sociodemographic/clinical characteristics and level of dependence. METHODS: This was a cross-sectional analytical study involving COPD patients on LTOT followed at the Oxygen Therapy Outpatient Clinic of the Federal University of São Paulo Hospital São Paulo, in the city of São Paulo, Brazil. Sociodemographic, clinical, and biochemical data were collected. We assessed QoL and level of dependence using the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) and the Katz index, respectively. Multiple linear regression models were constructed in order to determine the influence of these variables on QoL. RESULTS: We included 80 patients in the study. The mean age was 69.6 ± 9.1 years, and 51.3% were female. The lowest SF-36 scores were for the physical functioning and role-physical domains. All sociodemographic characteristics (except gender) were found to correlate significantly with the SF-36 domains mental health, vitality, role-physical, and social functioning. We also found that body mass index, PaO2, post-bronchodilator FEV1, hemoglobin, and Katz index correlated significantly with the physical functioning, mental health, role-physical, and bodily pain domains. In addition, oxygen flows were found to correlate negatively with the physical functioning, mental health, vitality, and role-emotional domains. CONCLUSIONS: Low scores for SF-36 domains, as well as the variables that negatively influence them, should be considered and analyzed during the development and implementation of strategies for improving the QoL of COPD patients on LTOT.OBJETIVO: Avaliar e correlacionar a qualidade de vida (QV) de pacientes com DPOC em uso de oxigenoterapia domiciliar prolongada (ODP) com suas características sociodemográficas/clínicas e o nível de dependência. MÉTODOS: Estudo transversal analítico com portadores de DPOC em ODP acompanhados no Ambulatório de Oxigenoterapia do Hospital São Paulo, Universidade Federal de São Paulo (UNIFESP), em São Paulo (SP). Os pacientes foram avaliados quanto aos dados sociodemográficos, clínicos e laboratoriais. A qualidade de vida e o nível de dependência foram avaliados pelo Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) e índice de Katz, respectivamente. Modelos de regressão linear múltipla foram construídos para verificar a influência dessas variáveis na QV. RESULTADOS: A média de idade dos 80 pacientes incluídos foi 69,6 ± 9,1 anos, e 51,3% eram do sexo feminino. Os escores dos domínios do SF-36 mais baixos foram capacidade funcional e função física. Correlações significantes foram encontradas entre características sociodemográficas (exceto gênero) e os domínios saúde mental, vitalidade, função física e aspectos sociais, assim como entre várias características clínicas/laboratoriais (índice de massa corpórea, PaO2, VEF1 pós-broncodilatador, hemoglobina e índice de Katz) e os domínios capacidade funcional, saúde mental, função física e dor corporal. Houve correlações negativas entre os fluxos de oxigênio e os domínios capacidade funcional, saúde mental, vitalidade e função emocional. CONCLUSÕES: Os baixos escores nos domínios do SF-36 e as variáveis que os influenciam negativamente devem ser considerados e analisados na elaboração e implementação de estratégias para a melhoria da QV de portadores de DPOC em ODP.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de EnfermagemUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Hospital São PauloUNIFESP, Escola Paulista de Enfermagem (EPE)UNIFESP, EPM, Hospital São PauloSciEL

Relationship of the APOE polymorphism and lipid profile: A population-based study in the Azores Islands (Portugal)

European Human Genetics Conference 2009: Abstract P17.18 em Livro de Resumos. Austria Center Vienna, Vienna, Austria, Saturday, May 23 – Tuesday, May 26, 2009.The factors leading to a two-fold mortality rate from coronary artery disease (CAD) in the Azores, as compared to Mainland Portugal, have not been elucidated. Previous studies reported a population tendency for hypercholesterolemia, one of the main factors contributing to the development of atherosclerosis (AT), considered the primary cause of CAD. Apolipoprotein E has a key role in plasma lipid metabolism, given its function as a ligand for cell-surface receptor mediated uptake of lipoproteins. Polymorphism in the apolipoprotein gene (APOE) results in three major isoforms encoded by three codominant alleles (E2, E3 and E4). With the purpose of establishing the pattern of variation at the APOE locus and determining its association with lipid profile, we studied a random sample of 298 unrelated, apparently healthy individuals of Azorean origin. In nearly 50% of the sample total cholesterol (TC) was above 200mg/dl; in 25% of the individuals LDL-cholesterol (LDL-C) was higher than 130 mg/dl. Allele frequencies were 0.0833, 0.8317 and 0.0850 for E2, E3 and E4, respectively. Genotype frequencies were higher for E3*E3 genotype (66.1%); genotype distribution displayed conformity with Hardy-Weinberg expectations. No differences in allelic frequencies were found in comparison with other Caucasian populations, namely with mainland Portugal. E3*E4 individuals presented the highest cholesterol levels. Analysis of variance performed with the most represented genotypes (E2*E3, E3*E3 and E3*E4) revealed a clear association between the genotypic composition and TC, as well as LDL-C, thus confirming in this population, the role of APOE as one of the genetic determinants of AT

Evaluación del tipo de curativo utilizado en cateter venoso central para hemodiálisis

OBJETIVOS: Avaliar a efetividade de dois tipos de curativos utilizados em cateter venoso central (CVC) em pacientes submetidos à hemodiálise; identificar a taxa de infecção no local de saída e de bacteremia comparando o curativo com gaze e micropore em relação ao filme transparente. MÉTODOS: Foi realizado um ensaio clínico randomizado controlado abrangendo 66 pacientes, sendo 33 nos grupos 1 e 2, respectivamente. No Grupo 1 o curativo utilizado foi gaze e micropore e no Grupo 2 filme transparente. Foram coletados os dados sócio demográficos, clínicos e os relacionados às infecções. Os 66 pacientes permaneceram no estudo até a indicação de retirada do cateter que ocorreu nos episódios de infecção quando foram realizadas culturas de óstio e da ponta do CVC e hemocultura quando indicado. RESULTADOS: Não houve diferença estatística significante quanto ao tipo de curativo e as variáveis estudadas. Os CVC posicionados a 90º em relação a pele apresentaram maior taxa de infecção por S. aureus. CONCLUSÃO: O uso do filme transparente não proporcionou redução de infecção, porém a análise qualitativa deste tipo de curativo teve melhor aceitação pelos pacientes e profissionais da Unidade de Diálise de um Hospital Universitário.OBJECTIVES: To evaluate the efficacy of two types of dressings used on central venous catheter (CVC) in patients undergoing hemodialysis and to determine the rate of local and systemic bacterial infection when using gauze and micropore dressings or transparent film dressings. METHODS: This study was a controlled randomized clinical trial with 66 subjects who were equally assigned to two groups (33 subjects per group). Group 1 used gauze and micropore dressings and group 2 used transparent film dressings. Measures consisted of a socio demographic questionnaire, clinical data, and catheter tip and blood culture tests. Subjects remained in the study until removal of the catheter. RESULTS: There were no statistically significant differences regarding the types of dressings. Positioning of CVCs at 90 degrees in relation to the skin had higher rate of infections by S. Aureus. CONCLUSION: Although the use of transparent film dressings did not reduce infection, qualitative data analysis suggested that this type of dressing was preferred by the patients and by the health care providers from a university hospital.OBJETIVOS: Evaluar la efectividad de dos tipos de curativos utilizados en cateter venoso central (CVC) en pacientes submetidos al hemodiálisis; identificar el índice de infección en el local de salida y de bacteremia comparando el curativo con gaza y micropore el con al filme transparente. MÉTODOS: Fue realizado un ensayo clínico randomizado controlado. En el Grupo 1 el curativo utilizado fue gaza y micropore y en el Grupo 2 filme transparente. Fueron colectados los datos sócio demográficos, clínicos y los relacionados a las infecciones. Los 66 pacientes permanecieron en el estudio hasta la indicación de retirada del cateter que ocurrió en los episodios de infección cuando fueron realizadas culturas de óstio y de la extremidad del CVC y hemocultura cuando indicado. RESULTADOS: Fueron incluídos 33 pacientes en cada grupo. No hubo diferencia estadística significante cuanto al tipo de curativo y las variables estudiadas. Los CVC posicionados a 90º en relación a la piel presentaron mayor índice de infección por S. aureus. CONCLUSIÓN: El uso del filme transparente no proporcionó reducción de infección, sin embargo el análisis cualitativo de este tipo de curativo tuvo mejor aceptación por los pacientes y profesionales

Primary adrenal insufficiency in adult population: a Portuguese multicentre study by the Adrenal Tumours Study Group

INTRODUCTION: Primary adrenal insufficiency (PAI) is a rare but severe and potentially life-threatening condition. No previous studies have characterized Portuguese patients with PAI. AIMS: To characterize the clinical presentation, diagnostic workup, treatment and follow-up of Portuguese patients with confirmed PAI. METHODS: This multicentre retrospective study examined PAI patients in 12 Portuguese hospitals. RESULTS: We investigated 278 patients with PAI (55.8% were females), with a mean age of 33.6±19.3 years at diagnosis. The most frequent presenting clinical features were asthenia (60.1%), mucocutaneous hyperpigmentation (55.0%) and weight loss (43.2%); 29.1% of the patients presented with adrenal crisis. Diagnosis was established by high plasma ACTH and low serum cortisol in most patients (43.9%). The most common etiology of PAI was autoimmune adrenalitis (61.0%). There were 38 idiopathic cases. Autoimmune comorbidities were found in 70% of the patients, the most frequent being autoimmune thyroiditis (60.7%) and type 1 diabetes mellitus (17.3%). Seventy-nine percent were treated with hydrocortisone (mean dose 26.3±8.3 mg/day) mostly in three (57.5%) or two (37.4%) daily doses. The remaining patients were treated with prednisolone (10.1%), dexamethasone (6.2%) and methylprednisolone (0.7%); 66.2% were also on fludrocortisone (median dose of 100 g/day). Since diagnosis, 33.5% of patients were hospitalized for disease decompensation. In the last appointment, 17.2% of patients had complaints (7.6% asthenia and 6.5% depression) and 9.7% had electrolyte disturbances. CONCLUSION: This is the first multicentre Portuguese study regarding PAI. The results emphasize the need for standardization in diagnostic tests and aetiological investigation and provide a framework for improving treatment.info:eu-repo/semantics/publishedVersio

SARS-CoV-2 introductions and early dynamics of the epidemic in Portugal

Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration with more than 50 laboratories distributed nationwide. Methods By applying recent phylodynamic models that allow integration of individual-based travel history, we reconstructed and characterized the spatio-temporal dynamics of SARSCoV-2 introductions and early dissemination in Portugal. Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland), which were consistent with the countries with the highest connectivity with Portugal. Although most introductions were estimated to have occurred during early March 2020, it is likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the first cases were confirmed. Conclusions Here we conclude that the earlier implementation of measures could have minimized the number of introductions and subsequent virus expansion in Portugal. This study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.We gratefully acknowledge to Sara Hill and Nuno Faria (University of Oxford) and Joshua Quick and Nick Loman (University of Birmingham) for kindly providing us with the initial sets of Artic Network primers for NGS; Rafael Mamede (MRamirez team, IMM, Lisbon) for developing and sharing a bioinformatics script for sequence curation (https://github.com/rfm-targa/BioinfUtils); Philippe Lemey (KU Leuven) for providing guidance on the implementation of the phylodynamic models; Joshua L.
