RESUMO

Aim: To investigate whether medical devices coated with a synthesized nanocomposite of poly(methylmethacrylate-co-dimethyl acrylamide) (PMMDMA) and silver nanoparticles (AgNPs) could improve their antibiofilm and antimicrobial activities. We also investigated the nanocomposite's safety. Materials & methods: The nanocomposite was synthesized and characterized using analytical techniques. Medical devices coated with the nanocomposite were evaluated for bacterial adhesion and hemolytic activity in vitro. Results: The nanocomposite formation was demonstrated with the incorporation of AgNPs into the polymer matrix. The nanocomposite proved to be nonhemolytic and significantly inhibited bacterial biofilm formation. Conclusion: The PMMDMA-AgNPs nanocomposite was more effective in preventing biofilm formation than PMMDMA alone and is a promising strategy for coating medical devices and reducing mortality due to hospital-acquired infections.

RESUMO

Objective: Some patients with cancer admitted to palliative care have relatively long survivals of 1 year or more. The objective of this study was to find out factors associated with prolonged survival. Methods: Retrospective case-control study comparing the available data of patients with cancer who survived more than 1 year after admission in a palliative care service with patients with cancer who survived 6 months or less. The intended proportion was 4 controls for each case. Patients were identified through electronic records from 2012 until 2018. Results: And 1721 patients were identified. Of those patients, 111 (6.4%) survived for at least 1 year, and 363 (21.1%) were included as controls according to the established criteria. The intended proportion could not be reached; the proportion was only 3.3:1. The median survival of cases was 581 days (range: 371-2763), and the median survival of controls was 57 days (range: 1-182). In the multivariable analysis, patients with a hemoglobin ≥ 10.6 g/dL and a creatinine level >95 µmol/L had a higher probability of living more than 1 year. In contrast, patients with abnormal cognition, pain, anorexia, liver metastases, an Eastern Cooperative Oncology Group performance status >1, and a neutrophil/lymphocyte ratio ≥ 3.43 had a low probability of living more than 1 year. Conclusion: Several factors were statistically associated positively or negatively with prolonged survival. However, the data of this study should be confirmed in other studies.

RESUMO

Abstract Objective: to analyze the prevalence of tuberculosis, coronavirus, chronic conditions and vulnerabilities among migrants and refugees in Brazil. Method: this is a cross-sectional study of the electronic survey type conducted with international migrants during the COVID-19 pandemic. Descriptive statistics was applied for the analysis, with calculation of position and dispersion measures. Regarding the categorical variables, relative and absolute frequencies were estimated. Results: the study participants were 553 migrants and refugees, verifying 3.07%, 7.2% and 27.3% prevalence of tuberculosis, COVID-19 and chronic conditions, respectively. Among the vulnerabilities, 32% reported unemployment, 37.6% moved to Brazil as a result of the social situation in their countries and 33.6% were living as refugees or sheltered people. Conclusion: tuberculosis, chronic diseases and COVID-19 presented higher prevalence values in migrants and refugees than in the general population. As this is a population group that still has significant difficulty accessing health services and social protection systems, based on diverse evidence, the study will subsidize public policies, Nursing care and the incorporation of new routines in the service.

RESUMO

INTRODUCTION: Mother's bond to the infant in the postpartum period plays an important role in the subsequent mother-infant relationship and the infant's socio-emotional functioning. Several maternal characteristics, such as attachment style and psychological flexibility, may contribute to the quality of mother-infant bonding, though literature examining these variables is still scarce. The present study aimed to examine the impact of mother's attachment on mother-infant bonding in the first month postpartum and the mediating role of psychological flexibility on that association. METHODS: Participants were 226 mothers of an infant up to 9 months old, who reported on their own attachment style (in terms of anxiety, comfort with proximity, trust in others), psychological flexibility (in terms of openness to experience, behavioural awareness, valued action) and mother-infant bonding. RESULTS: Results showed that mother's attachment anxiety predicted a bond with the infant directly and indirectly via mother's psychological flexibility, specifically through behavioural awareness and valued action. Trust in others had an impact on mother-infant bonding through behavioural awareness, whereas comfort with proximity influenced mother-infant bond indirectly, via valued action. Finally, mothers' civil status, schooling and number of children were relevant to better understand the variance of our mediating and dependent variables. DISCUSSION: Our findings highlight the importance of mother's attachment and psychological flexibility in promoting the quality of mother-infant bonding, which can inform future intervention programmes targeting modifiable factors, such as psychological flexibility, to promote early positive parent-infant relationships, particularly for single, first-time mothers, with higher levels of education.

RESUMO

BACKGROUND: Integrase strand transfer inhibitor-based regimens are recommended for first-line therapy in human immunodeficiency virus type 2 (HIV-2). Nonetheless, dolutegravir (DTG) clinical trial data are lacking. METHODS: We conducted a phase 2, single-arm, open-label trial to evaluate the safety and efficacy of a triple therapy regimen that included DTG in persons with HIV-2 (PWHIV-2) in Portugal. Treatment-naive adults receive DTG in combination with 2 nucleoside reverse transcriptase inhibitors (NRTIs). Treatment efficacy was evaluated by the proportion of patients who achieved a plasma viral load (pVL) <40 copies/mL and/or by the change from baseline in CD4+ T-cell count and in CD4/CD8 ratio at week 48. RESULTS: A total of 30 patients were enrolled (22 women; median age, 55 years). At baseline, 17 (56.7%) individuals were viremic (median, pVL 190 copies/mL; interquartile range [IQR], 99-445). The median CD4 count was 438 cells/µL (IQR, 335-605), and the CD4/CD8 ratio was 0.8. Three patients discontinued the study. At week 48, all participants (27) had pVL <40 copies/mL. No virological failures were observed. Mean changes in CD4 count and CD4/CD8 ratio at week 48 were 95.59 cells/µL (95% confidence interval [CI], 28-163) and 0.32 (95% CI, .19 to .46). The most common drug-related adverse events were headache and nausea. One participant discontinued due to central nervous system symptoms. No serious adverse events were reported. CONCLUSIONS: DTG plus 2 NRTIs is safe and effective as first-line treatment for PWHIV-2 with a tolerability profile previously known. No virological failures were observed that suggest a high potency of DTG in HIV-2 as occurs in HIV-1. CLINICAL TRIALS REGISTRATION: M NCT03224338.

RESUMO

Introduction The aim of this systematic review and meta-analysis was to evaluate the effects of maxillary expansion on adults with obstructive sleep apnoea (OSA).Methods Electronic searches up to July 2021 in eight electronic databases were conducted. Study selection, data extraction, risk of bias evaluation using ROBINS-I, quality of evidence assessment using GRADE and meta-analyses were performed.Results The electronic searches yielded 1,007 studies. Following the application of the eligibility criteria, 15 articles were fully read and five studies were included. The studies evaluated the effects of surgically assisted rapid maxillary expansion in adults with OSA. The meta-analysis demonstrated an improvement in Apnoea-Hypopnea Index (AHI) (MD = -9.91, CI = -14.57 to -5.25), Oxygen Desaturation Index (ODI) (MD = -7.95, CI = -12.23 to -3.67), and Epworth Sleepiness Scale (ESS) (MD = -4.40, CI = -6.39 to -2.40). ROBINS-I indicated serious, no information and critical risk of bias for the included studies. The quality of the evidence was very low.Conclusion The findings herein suggest that maxillary expansion could improve OSA in adults in the short term.

RESUMO

The present study is a systematic review of the evaluation of screening programs as a strategy for early detection of oral cancer. The aim of this study was to assess whether screening through visual inspection is able to identify injuries in early stages, to increase survival, and to decrease the incidence and mortality of oral cancer. Studies using visual inspection to screen for oral cancer and potentially malignant lesions in apparently healthy individuals over 18 years without previous diagnosis of the disease were included. The MEDLINE/PubMed, Cochrane databases Library, EMBASE, and LILACS, including manual search and gray literature, were searched through January 2021 with no language or date restrictions. The risk of bias and the methodological quality were evaluated according to the appropriate tool for each study design. The analysis of the results was narrative. Seventeen studies were reviewed that included cohort, accuracy, and randomized clinical trial studies. The tracking type performed was opportunistic and organized in a variety of environments. The age of participants ranged between 18 and 60 years old and, in some programs, only people with risk habits for oral cancer were included. The screeners were healthcare professionals, physicians, and dentists. Two studies reported data on the incidence rate of severe cases and mortality and showed a reduction when patients were at risk for the disease and participated in the program more than once. A limitation of this review was the great variability observed in the estimates of the screening effectiveness among the studies, which made comparisons difficult. If a screening program is continuous and able to ensure the inclusion of high-risk individuals, it can contribute to improvement in survival rates with a change of stage and can have a significant impact on incidence and mortality due to the disease.

RESUMO

INTRODUCTION: Hyponatremia is frequent in cancer patients, as many studies carried out in these patients have shown. However, there are only a few studies carried out at the end of life and in palliative care. The aim of this study was to determine the prevalence of hyponatremia in cancer patients in the palliative care department of an oncology center and its association with survival. MATERIAL AND METHODS: The study included the first 300 patients hospitalized in the palliative care department in 2017. Survival was measured from the day of hospitalization until death. RESULTS: Serum sodium was measured in 170 (59%) patients. The median serum concentration was 135 mmol/L (109 to 145). Among 91 (54%) patients, serum sodium was within the normal range, 59 (35%) had mild hyponatremia, 13 (8%) had moderate and seven (4%) had profound hyponatremia. The median survival was 13 days (1 to 1020). Serum sodium was not significantly associated with survival (p = 0.463). Regarding other variables, the Eastern Cooperative Oncology Group performance status was significantly associated with survival, while gender, age, primary cancer and number of metastatic sites were not. DISCUSSION: Hyponatremia, mainly mild and moderate, was found in almost half of the patients included in this study. However, unlike other studies, hyponatremia was not associated with a poorer prognosis. CONCLUSION: Hyponatremia is common in cancer patients receiving palliative care but did not seem to influence survival.


Introdução: A hiponatremia é frequente em doentes com cancro, como muito estudos realizados nesses doentes mostraram. Contudo, há poucos estudos no fim da vida e em cuidados paliativos. O objectivo deste trabalho foi estudar a prevalência da hiponatremia em doentes oncológicos num serviço de cuidados paliativos de um centro oncológico e a sua associação com a sobrevivência. Material e Métodos: O estudo incluiu os primeiros 300 doentes internados no serviço de cuidados paliativos em 2017. A sobrevivência foi medida do dia da hospitalização até à morte. Resultados: O sódio plasmático foi medido em 170 (59%) doentes. A mediana da concentração de sódio plasmático foi 135 mmol/L (109 a 145). Em 91 (54%) doentes, o sódio plasmático estava dentro dos valores de referência, 59 (35%) tinham hiponatremia ligeira, em 13 (8%) era moderada e sete (4%) tinham hiponatremia profunda. A mediana da sobrevivência foi de 13 dias (1 a 1020). O sódio plasmático não apresentou uma associação estatisticamente significativamente associado com a sobrevivência (p = 0,463). Quanto a outras variáveis, o estado de performance do Eastern Cooperative Oncology Group associou-se significativamente à sobrevivência, o que não se verificou com o género, a idade, o tumor primário e o número de locais de metástases. Discussão: A hiponatremia, principalmente ligeira e moderada, ocorreu em quase metade dos doentes incluídos neste estudo. No entanto, ao contrário de outros estudos, a hiponatremia não se associou a um pior prognóstico. Conclusão: A hiponatremia é comum nos doentes oncológicos em cuidados paliativos, mas não parece influenciar a sobrevivência.

RESUMO

Objetivo: Relatar a experiência referente a atendimentos compartilhados às gestantes na Atenção Primária à Saúde no município de Guaiuba (CE), evidenciando a oferta do cuidado ampliado como recurso para o fortalecimento de vínculos entre usuárias e Equipes de Saúde da Família e, também, analisando a importância do exercício da interprofissionalidade para a qualificação da atenção à saúde. Métodos: Trata-se de um relato de experiência de natureza descritiva e abordagem qualitativa, desenvolvido a partir da atuação conjunta entre uma assistente social (residente) e duas enfermeiras nas consultas de pré-natal em duas Unidades Básicas de Saúde de Guaiuba (CE), entre 11 de março e 25 de junho de 2020. Resultados: Com escuta qualificada e uso de uma linguagem mais acessível, orientamos as usuárias sobre seus direitos e discutimos sobre os determinantes e condicionantes que afetam sua saúde. Discussão: O exercício da interprofissionalidade contribui para melhorar a segurança do paciente, colabora para humanizar as práticas e o bem-estar dos próprios trabalhadores e abre a possibilidade de uma práxis diferente devido à integração de conhecimentos. Considerações finais: A experiência foi bem sucedida e fundamental para a efetivação do cuidado integrado às gestantes com base em um serviço acolhedor e inclusivo, servindo como parâmetro para as usuárias dos territórios adscritos das UBS participantes. Ademais, o(a) assistente social na saúde precisa buscar a efetivação do Projeto Ético-Politico da profissão para atingir seus objetivos e fazer com que os demais profissionais compreendam sua atuação, entendendo quais demandas devem ser compartilhadas com o Serviço Social.

RESUMO

BACKGROUND: The provision of care and monitoring of health are essential for indigenous Venezuelans from the Warao ethnic group, who are at risk of decimation. OBJECTIVE: Analyze a Local Action Plan (LAP) to promote access to the health system of indigenous Venezuelans from the Warao ethnic group (IVWEG) in Manaus, Brazil. METHOD: A mixed-methods study was performed. Quantitative data were collected to assess the provision of care and monitoring of health conditions in IVWEG through a survey that was self-completed by healthcare providers. Qualitative narrative data were collected to gain insight into IVWEG that seek care. We applied descriptive statistics, grouping analysis (GA) by hierarchical levels, and multiple correspondence analysis (MCA). Content analysis was applied to qualitative data. RESULTS: 106 healthcare providers participated in the study, with the following characteristics: 94 (88.7%) females, 67 (63.2%) pardo race/color, 40 (37.7%) working in primary healthcare, and 49 (46.2%) nurses. In addition, 43 (40.6%) of the healthcare providers reported providing care to IVWEG. Among the providers, 89 (84%) had received training for assisting IVWEG. Additionally, 30 IVWEG were enrolled for interviews in the qualitative phase. The barriers to seeking care were language, distance to health units, and lack of money for transportation. The LAP proved to facilitate access to the health system by indigenous Venezuelans from the Warao ethnic group in Manaus. The study contributed to knowledge on a LAP addressed to IVWEG and helped improved their access to the health system, providing appropriate training for healthcare providers and other relevant actors by implementing a coherent and consistent public health policy at the local level.

RESUMO

BACKGROUND: The assessment of adherence to warfarin therapy is useful in clinical practice due to its wide variability in dose-response and risks of complications. The aim of this study was to investigate validated instruments used to assess adherence to warfarin therapy. METHODS: Information was collected from the MEDLINE (PubMed), LILACS, EMBASE, and Cochrane Library databases. Search strategies were applied for each database, with no time limit or language restriction. Inclusion criteria consisted of study participants of ≥ 18 years of age, from both sexes, on chronic anticoagulation with warfarin for any indication and the use of validated instruments to assess adherence to warfarin therapy. Exclusion criteria consisted of duplicate articles, narrative or systematic reviews, and meta-analyses, as well as case reports/series and experimental studies involving animals. Two independent reviewers performed the following steps: evaluation of titles/abstracts, selection of studies after full reading, data extraction, and evaluation of potential bias. Discrepancies were resolved by a third reviewer. RESULTS: Overall, 19 articles were selected for this systematic review, including 17 cross-sectional studies, one cohort study, and one quasi-experimental study, published from 2009 to 2019. The validated instruments identified in this review were Morisky Medication Adherence Scale (MMAS), the eight-item Morisky Medication Adherence Scale (MMAS-8), Measurement of Treatment Adherence (MTA), and Brief Medication Questionnaire (BMQ). Only MMAS-8 was tested for reliability, using the internal consistency assessment, with Cronbach's α range 0.56-0.71. CONCLUSIONS: This review highlighted a gap in knowledge regarding the scarcity of validated instruments to assess adherence to warfarin therapy. Limitations were found in instruments that comprised the assessment of the isolated use of medication and the lack of analysis of other relevant therapeutic aspects. Future studies are needed to develop and validate more comprehensive instruments in an attempt to assess adherence to warfarin therapy. PROSPERO: Registration number CRD42019128324.

RESUMO

BACKGROUND: Migrants are a high priority group for TB control measures due to their high exposure to risk factors such as poverty and social vulnerability. The study aimed to identify factors associated with latent TB among international migrants living in four Brazilian state capitals. This was a cross-sectional study conducted in September and October 2020 in a sample of 903 international migrants living in four Brazilian state capitals: Boa Vista/RR (458), Manaus/AM (136), São Paulo/SP (257), and Curitiba/PR (52). Data were collected with a questionnaire consisting of open and closed questions on personal characteristics, information on TB, and use of preventive measures. Tuberculin skin test (TST) was performed, with reading after 72 h by trained nurses and using 5 mm induration as the positive cutoff. Chi-square test (X2) and Fisher's exact test, both two-tailed, were used to compare statistically significant levels of association between the migrants´ sociodemographic characteristics, vulnerability, and latent TB infection (LTBI). Binary logistic regression was applied to calculate odds ratios and respective 95% confidence intervals. For all the tests, type I error of 5% was defined as statistically significant (p < 0.05). RESULTS: Prevalence of LTBI among migrants was 46.1% in Manaus/AM, 33.3% in São Paulo/SP, 28.1% in Curitiba/PR, and 23.5% in Boa Vista/RR. Factors associated with latent infection were age, male gender, and brown or indigenous race. CONCLUSIONS: The study showed high prevalence of latent TB among international migrants.

RESUMO

Polycystic ovary syndrome (PCOS) is defined as a reproductive endocrine disease that results in a low-grade inflammatory and pro-oxidant state. Dietary factors, including n-3 fatty acids, may have a key role in improving metabolic disorders in PCOS patients. The present study aimed to investigate the influence of n-3 fatty acid supplementation on inflammatory and oxidative stress (OS) markers in patients with PCOS. A systematic literature search of Medline/PubMed, Cochrane Central Register of Controlled Trials, Scopus and Lilacs, until November 2019, was conducted. Randomised clinical trials that reported inflammatory and OS markers as endpoints in women with PCOS receiving n-3 fatty acid supplementation were included. The pooled estimates of the weighted mean differences (WMD) and the standard mean differences (SMD) were calculated. Random effects models were adopted to measure the pooled outcomes. Among the 323 studies retrieved, ten fulfilled the inclusion criteria for a meta-analysis. We founded a significant decrease in high-sensitivity C-reactive protein (hs-CRP) (SMD -0·29 (95 % CI -0·56, -0·02) mg/l) and an increase in adiponectin (WMD 1·42 (95 % CI 1·09, 1·76) ng/ml) concentrations in the intervention group when compared with the placebo group. No statistically significant results were found in the meta-analysis for visfatin, nitric oxide, GSH or malondialdehyde levels or total antioxidant capacity. The data suggest that supplementation of n-3 fatty acids could reduce the inflammatory state in women with PCOS, through a decrease in hs-CRP and an increase in adiponectin levels.

RESUMO

INTRODUCTION: A significant proportion of patients with advanced primary or metastatic intrathoracic malignancy will eventually develop central airway obstruction. The morbidity associated with malignant airway obstruction (MAO) is considerable and the management is difficult. Our aim was to evaluate the outcomes of tracheobronchial stenting in patients with MAO and its role in palliative care. MATERIAL AND METHODS: This retrospective study involved a consecutive case series of patients with advanced cancer with MAO who underwent tracheobronchial stenting between August 2014 and August 2019. The European Cooperative Oncology Group (ECOG) scale was used to evaluate patient functional status before and after tracheobronchial stenting. Univariate survival analysis included Kaplan-Meier curves with Log-Rank test, while Cox regression was used as a multivariate analysis. RESULTS: We included 28 patients with median age of 55.0 years (interquartile range = 49.3-66.5) and 89.3% male. The most frequent primary tumour was the esophagus followed by lungs. The majority of the patients (75%) expressed immediate symptom relief after stenting and there was a significant improvement in the mean ECOG performance status (PS; P = .005). There was no intraprocedure mortality and complications were observed in 6 patients. The median survival after airway stenting was 39.0 days (95% CI = 32.2-45.8) with poorer PS after stent insertion associated with lower overall survival (hazard ratio = 2.3 [95% CI = 1.1-4.9], P = .030) on multivariate analysis. CONCLUSION: Airway stent is a safe and effective procedure that offers rapid palliation of symptoms with no major complications. Therefore, stent placement should be considered as part of the treatment of patients with terminal cancer.

RESUMO

Thrombocytopenia-absent radius (TAR) syndrome is a congenital malformation in which affected individuals present reductions in the number of platelets, hypoplasia, or absence of radial bone unilaterally or bilaterally. Hematologic, skeletal, cardiac (particularly tetralogy of Fallot and septal-atrial defects), and gastrointestinal anomalies are most commonly associated with TAR syndrome. Skeletal changes result in a higher risk of dental and craniofacial trauma in patients with the syndrome. Thus, it is important for the dentist to be aware of the characteristics of TAR syndrome and its clinical management for better care of these patients. The objective of this study is to describe a case report of a 26-year-old patient with TAR syndrome with a history of trauma and root fracture of tooth 11 and alveolar bone ridge. During anamnesis, root fractures requiring the extraction of the 11 tooth, alveolar bone ridge fracture in the adjacent region, and dental trauma were observed. A hematological evaluation and blood and radiological examinations were performed. Osseointegrated implant was performed using the guided surgery and flapless technique, as well as prosthetic rehabilitation in the affected region. This report discusses the importance of careful planning, such as the use of incisions and conservative surgery, techniques for alveolar ridge preservation, gingival manipulation, and prosthesis confection. The patient was attended by a hematologist throughout the treatment. Key words:TAR syndrome, absent radii and thrombocytopenia, dental implants, oral surgery.

RESUMO

BACKGROUND AND OBJECTIVE: Managed entry agreements (MEAs) consist of a set of instruments to reduce the uncertainty and the budget impact of new high-priced medicines; however, there are concerns. There is a need to critically appraise MEAs with their planned introduction in Brazil. Accordingly, the objective of this article is to identify and appraise key attributes and concerns with MEAs among payers and their advisers, with the findings providing critical considerations for Brazil and other high- and middle-income countries. METHODS: An integrative review approach was adopted. This involved a review of MEAs across countries. The review question was 'What are the health technology MEAs that have been applied around the world?' This review was supplemented with studies not retrieved in the search known to the senior-level co-authors including key South American markets. It also involved senior-level decision makers and advisers providing guidance on the potential advantages and disadvantages of MEAs and ways forward. RESULTS: Twenty-five studies were included in the review. Most MEAs included medicines (96.8%), focused on financial arrangements (43%) and included mostly antineoplastic medicines. Most countries kept key information confidential including discounts or had not published such data. Few details were found in the literature regarding South America. Our findings and inputs resulted in both advantages including reimbursement and disadvantages including concerns with data collection for outcome-based schemes. CONCLUSIONS: We are likely to see a growth in MEAs with the continual launch of new high-priced and often complex treatments, coupled with increasing demands on resources. Whilst outcome-based MEAs could be an important tool to improve access to new innovative medicines, there are critical issues to address. Comparing knowledge, experiences, and practices across countries is crucial to guide high- and middle-income countries when designing their future MEAs.
