Associations of the consumption of unprocessed red meat and processed meat with the incidence of cardiovascular disease and mortality, and the dose-response relationship: A systematic review and meta-analysis of cohort studies.

OBJECTIVES: The aim of this study was to examine the associations of unprocessed red meat and processed meat consumption with cardiovascular disease (CVD) incidence and mortality, and the dose-response relationship. METHODS: Published literature was retrieved through a structured search of 10 electronic databases: MEDLINE/PubMed, Scopus, SciELO, LILACS, ScienceDirect, Web of Science, Cochrane (CENTRAL), WHOLIS, PAHO and Embase, without language or year of publication restrictions. In addition, we searched the references of published studies. This systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes: The PRISMA Statement. RESULTS: Twenty-one prospective cohort studies were included in the systematic review. The CVDs evaluated in the inserted studies were stroke, heart failure (HF) and coronary heart disease (CHD). Considering the heterogeneity found in the studies, for the meta-analysis, 9 articles were included. The results presented in the meta-analysis of the association of consumption of unprocessed red meat and CVD indicated that there was a significant association with total stroke incidence (RR 1.10; 95%; CI 1.01 to 1.19; p = 0.02). There was no association with Ischemic stroke incidence, nor CHD Mortality with consumption of unprocessed red meat. However, for Hemorrhagic Stroke Mortality the assessment in the consumption of unprocessed red meat showed an association of protection for women (RR 0.64; 95%; CI 0.45 to 0.91; p = 0.01). As for the results of the meta-analysis of the association between consumption of processed meat and CVD, they indicated that there was a significant association with total stroke incidence (RR 1.17; 95%; CI 1.08 to 1.26; p < 0.0001). There was no association with Ischemic stroke, nor with CHD Mortality with consumption of processed meat. Some studies that showed no association of risk, presented a significant linear trend dose response for the association of the consumption of unprocessed red meat (Bernstein et al. 2010; Nagao et al. 2012) or processed meat (Bernstein et al. 2012) and CVD. CONCLUSION: According to the results found in the meta-analysis, the consumption of unprocessed red meat and processed meat are associated with the incidence of stroke, however, no positive association was observed in relation to mortality from CVD. This systematic review and meta-analysis protocol was registered on the PROSPERO (number: CRD42019100914).

Training in communication skills for self-efficacy of health professionals: a systematic review.

BACKGROUND: Communication skills are essential for health professionals to establish a positive relationship with their patients, improving their health and quality of life. In this perspective, communication skills training can be effective strategies to improve the care provided by professionals in patient care and the quality of health services. OBJECTIVE: To identify the best available evidence on training programs in communication skills to promote changes in attitude and behavior or self-efficacy of health professionals. METHODS: Systematic searches were performed in eight databases, evaluating Randomized Controlled Trials and quasi-experimental studies with a control group, focusing on training communication skills for health professionals, who assessed self-efficacy or behaviors related to these skills. The phases of study selection and data extraction were carried out by two independent researchers, and the conflicts were resolved by a third. The risk of bias was assessed using the Cochrane method. RESULTS: Eight studies were included in the review. Most programs lasted between 4½ h and 2 days, involved information about communication skills and the content was applied to the health professionals' context. Several teaching strategies were used, such as lectures, videos and dramatizations and the evaluation was carried out using different instruments. Improvements in the performance and in the self-efficacy of communication skills were observed in the trained groups. The RCT had a low risk of bias and the quasi-experimental studies had a moderate risk. CONCLUSION: Training in communication skills can improve the performance and self-efficacy of health professionals. Programs that approach the conceptual issues and promote the space for experiential learning could be effective in communication skills training for professionals. PROSPERO: CRD42019129384.

Is rituximab effective for systemic sclerosis? A systematic review and meta-analysis.

BACKGROUND: Systemic sclerosis (SSc) is a clinically complex and challenging disease, that leads to skin fibrosis. Its most frequent complication is interstitial lung disease (ILD), which leads to a worse prognosis. In this situation, cyclophosphamide is considered the gold standard for its treatment, despite the controversies regarding its efficacy and toxicity. However, studies using rituximab (RTX) have shown that this drug may be a promising therapeutic option. OBJECTIVES: This paper objective was to analyze the scientific evidence on the RTX effects on SSc. METHODS: A systematic review (SR) was performed including clinical trials (CTs) on the use of RTX in SSc, published up to May 2020. The studies were identified through systematic searches in bibliographic databases using a predefined search strategy. The following databases were used: PUBMED, SCOPUS, SCIELO, LILACS, SCIENCE DIRECT, WEB OF SCIENCE, COCHRANE, WHOLIS, PAHO and EMBASE. Also, a manual search was performed. The methodological quality of the studies was determined using Jadad scale, Risk of Bias Tool (RoB 2.0) and Risk of Bias in Non-Randomized Studies - of Interventions tool (ROBINS-I). A meta-analysis of the randomized CTs was performed, using Review Manager. RESULTS: Ten CTs were included in this SR. Of these, three were randomized and seven were non-randomized. Five showed a statistically significant improvement in forced vital capacity (FVC) at some time during follow-up. Regarding the skin, eight studies showed statistically significant improvements according toa the modified Rodnan skin score. The meta-analysis found positive effects of RTX in SSc, with a statistical significance for lung disease. CONCLUSION: Rituximab is a promising strategy for the SSc-associated ILD and cutaneous fibrosis treatment. PROSPERO registration number: CRD42019132018.

Media and scientific communication about the COVID-19 pandemic and the repercussions on the population's mental health: A protocol for a systematic review and meta-analysis.

BACKGROUND: Good communication strategies are essential in times of crisis, such as the coronavirus pandemic. The dissemination of inaccurate information and the need for social isolation to control coronavirus disease 2019 (COVID-19) have shown a negative impact on the population, causing damage to mental health, with the appearance or worsening of symptoms of stress, fear, anxiety, and depression. Thus, the systematic review study is intended to gather evidence on the impact of information about COVID-19 on the mental health of the population. METHODS: This systematic review protocol is conducted using the guidelines of the preferred reporting items for systematic reviews and meta-analyses protocols and the Cochrane Handbook for Systematic Reviews of Interventions. The review aims to include published studies that address the exposure of the general population to information about COVID-19, through observational and experimental studies, which consider the following outcomes: fear, stress, anxiety, and depression. Thus, a comprehensive research strategy will be conducted in the following databases: PubMed / Medline, Scopus, Web of Science, EMBASE, Science Direct, CINAHL, PsycINFO and Cochrane Central Register of Controlled Trials (CENTRAL). Two independent reviewers will perform all procedures, such as study selection, data collection, and methodological evaluation. Disagreements will be forwarded to a third reviewer. RevMan 5.3 software will be used for data analysis. RESULTS: This systematic review will provide evidence of the influence of access to and consumption of media and scientific information about COVID-19 on the mental health of the population. It will consider information about the characterization of the study and the population studied, clinical and epidemiological information on mental health, and data on access to and consumption of media and scientific information. DISCUSSION: The results should inform about the consequences of communication about the new coronavirus on the emergence or worsening of psychological and psychiatric symptoms, allowing to develop strategies to achieve effective communication of information to promote the mental health of the population.

Acesso e implicações da automedicação em idosos na atenção primária à saúde / Access and implications of self-medication in the elderly in primary health care / Acceso e implicaciones de la automedicación en ancianos en la atención primaria de salud

Objetivo: avaliar o acesso e sua interferência no processo da automedicação em idosos. Método: estudo de avaliação de serviços com corte seccional, com idosos de ambos os sexos, que utilizam os serviços da atenção primária à saúde, pertencente ao município de Natal, Rio Grande do Norte. Foram realizadas 121 entrevistas, em nove unidades básicas de saúde no ano de 2016. Os dados foram analisados a partir do teste T de Student e o teste Qui-Quadrado, para determinar a significância estatística entre as variáveis independentes e os desfechos. Resultados: a prevalência de automedicação foi de 66,7%, associada negativamente ao acesso, atributo desfavoravelmente avaliado pelos idosos (média de 3,4). A febre (19,8%) foi a principal queixa motivadora de automedicação, sendo os analgésicos, os fármacos mais utilizados na automedicação. A automedicação apresentou associação significativa entre idade e medicamento sem prescrição médica para febre e cefaleia. Conclusão: apesar de não ter encontrado associação entre acesso e automedicação, foi identificada a alta prevalência dessa prática. Assim, é necessário que haja o fortalecimento da atenção primária, por meio de políticas voltadas às necessidades dos idosos com abordagem integral e com maior acesso ao atendimento multidisciplinar e multiprofissional, e não apenas a oferta de medicamentos.

Objective: to evaluate the access and its interference in the process of selfmedication in the elderly. Method: evaluation study of cross-sectional services with elderly men and women who use primary health care services in the city of Natal, Rio Grande do Norte. A total of 121 interviews were conducted in 09 basic health units of the municipality in 2016. Data were analyzed using the Student's ttest and chi-square test to determine the statistical significance between the two independent variables and outcomes. Results: the prevalence of self-medication was 66.7%, being negatively associated with access, a negatively assessed attribute in the perception of the elderly, showing an unsatisfactory degree (mean of 3.4). Fever (19.8%) was the main motivating complaint of self-medication, with analgesics being the most used self-medication. Self-medication showed a significant association between age and nonprescription medication for fever and headache. Conclusion: despite not finding an association between access and selfmedication, the high prevalence of this practice was identified. Thus, it is necessary to strengthen primary care through policies focused on the needs of the elderly with a comprehensive approach and greater access to multidisciplinary and multiprofessional care, not just the supply of medicines.

Rituximab in systemic sclerosis: A protocol for systematic review.

BACKGROUND: Systemic sclerosis (SSc) is a clinically complex and challenging disease, the most frequent complication of which is interstitial lung disease, which leads to a worse prognosis. In this situation, cyclophosphamide is considered the criterion standard for treatment, despite the controversies regarding its efficacy and toxicity. However, studies using rituximab (RTX) have shown that this drug may be a promising therapeutic option. The objective is to describe a protocol of a systematic review (SR) that analyzes the scientific evidence on the effects of RTX on SSc. METHODS: This protocol is guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. The databases to be searched are PubMed, Scopus, SciELO, LILACS, ScienceDirect, Web of Science, COCHRANE, WHOLIS, PAHO, and EMBASE. The studies that would be included in SR are clinical trials that evaluate the use of RTX in patients with SSc who meet the classification criteria for the disease according to American College of Rheumatology and European League Against Rheumatism (2013) and/or LeRoy criteria will be included in the SR. The data to be extracted are related to the characteristics of the studies: authors, year of publication, study location, type of study, sample size and age, patient characteristics, duration of intervention, therapeutic scheme, follow-up time, main variables, and main results. RESULTS: In our study, we hope to find articles presenting new evidence supporting treatment of SSc with RTX. CONCLUSIONS: The SR will present results of scientific evidence for the effects of RTX in SSc. We hope that the results could strengthen clinical decisions for the best treatment of SSc and guide future researches. PROSPERO REGISTRATION NUMBER: CRD42019132018.

Red meat consumption, risk of incidence of cardiovascular disease and cardiovascular mortality, and the dose-response effect: Protocol for a systematic review and meta-analysis of longitudinal cohort studies.

BACKGROUND: Red and (particularly) processed meats are high in cholesterol and saturated and solid fatty acids. Their consumption is considered one of the risk factors for metabolic disorders. Numerous studies demonstrated a possible association between red meat consumption and cardiovascular disease (CVD). In this protocol, we propose a systematic review of the literature to examine the associations of red meat consumption with CVD incidence and mortality, and explore the potential dose-response relationship. METHODS: We will search MEDLINE/PubMed, Scopus, SciELO, LILACS, ScienceDirect, Web of Science, Cochrane (CENTRAL), WHOLIS, PAHO, and Embase. We will include prospective epidemiological studies (longitudinal cohort). Risk of bias will be assessed using the Newcastle-Ottawa scale (NOS). Four independent researchers will conduct all evaluations. Disagreements will be referred to a fifth reviewer. We will summarize our findings using a narrative approach and tables to describe the characteristics of the included studies. The heterogeneity between trial results will be evaluated using a standard chi-squared test with P < .05. We will conduct the study in accordance with the guideline of the Preferred Reporting Items for Systematic Review and Meta-analyses Protocols (PRISMA-P). RESULTS: This review will evaluate the association between red meat consumption and incidence of CVD and mortality (primary outcome measures). The secondary outcome measure will include the dose-response effect. CONCLUSION: The findings of this systematic review will summarize the latest evidence of the association between red meat consumption and incidence of CVD and mortality and the dose-response effect through a systematic review and meta-analysis.

Training programs in communication skills to improve self-efficacy for health personnel: Protocol for a systematic review and meta-analysis.

BACKGROUND: Patient-centered care should be the focus of health services, where improvements in the communication skills of health professionals promote excellent health and quality care. Thus, this study is a protocol for a systematic review and meta-analysis to evaluate the effectiveness of training programs in communication skills to promote self-efficacy in the communication of health personnel. METHODS: This systematic review protocol is conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) statement guidelines and the Cochrane Handbook of Systematic Reviews of Interventions. The review should include studies carried out with health professionals who have undergone training in communication skills aimed at promoting their self-efficacy. Clinical trials (randomized, non-randomized), community trials, and quasi-experimental studies should be included. Therefore, the comprehensive search strategy will be conducted in the following databases: PubMed/Medline, Scopus, Web of Science, EMBASE, Science Direct, CINAHL, PsycINFO, and the Cochrane Central Register of Controlled Trials (CENTRAL). Two independent reviewers will conduct all study selection procedures, data extraction, and methodological evaluation, and disagreements will be referred to a third reviewer. RevMan 5.3 software will be used to gather data and perform the meta-analysis if possible. RESULTS: This systematic review will provide evidence on more effective programs for communication skills training and will consider information such as duration, educational strategies, assessment measures, and outcomes that promote health worker self-efficacy. DISCUSSION: This systematic review should provide evidence for effective communication skills training for health professionals in order to guide new strategies for quality care. DISSEMINATION AND ETHICS: The findings of this scoping review will be disseminated in print, at conferences, or via peer-reviewed journals. Ethical approval is not necessary as this paper does not involve patient data. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019129384.

Multicentre cross-sectional study on adverse events and good practices in maternity wards in Brazil and Mexico: same problems, different magnitude.

OBJECTIVE: To evaluate the quality of delivery care in maternity wards in Brazil and Mexico based on good practices (GP) and adverse events (AE), in order to identify priorities for improvement. DESIGN: A multicentre cross-sectional study with data collection from medical records between 2015 and 2016 to compare indicators of maternal and neonatal GP and EA based on the Safe Childbirth Checklist and standardised obstetric quality indicators. Two Brazilian and five Mexican maternity wards participated in the study. Descriptive statistics and χ2 tests were performed to assess performance and significant differences between the hospitals investigated. SAMPLING: We analysed 720 births in Brazil and 2707 in Mexico, which were selected using a systematic random sampling of 30 medical records every fortnight for 12 2-week periods in Brazil and 18 2-week periods in Mexico. We included women and their newborns, excluding those with congenital malformations. RESULTS: The Mexican hospitals showed greater adherence to GP (58.2%) and a lower incidence of AE (12.9%) than the participating institutions in Brazil (26.8% compliance with GP and 16.0% AE). In spite of these differences, the relative importance of particular quality problems and type of AE are similar in both countries. Tertiary hospitals, caring for women at higher risk, have significantly (p<0.001) higher rates of AE (27.2% in Brazil and 29.6% in Mexico) than institutions attending women at lower risk, where the frequency of AE ranges from 4.7% to 11.2%. Differences were significant (p<0.001) for most indicators of GP and AE. CONCLUSION: Data from outcome and process measures revealed similar types of failures in the quality of childbirth care in both countries and indicate the need of rationalising the use of antibiotics for the mother and episiotomy, encouraging greater adherence to partograph and to the use of magnesium sulfate for the treatment of severe preeclampsia/eclampsia.

Adaptation and validation of the World Health Organization's on Safe Childbirth Checklist for the Brazilian context / Adaptação e validação da lista de verificação do parto seguro da Organização Mundial da Saúde para o contexto brasileiro

Abstract Objectives: to culturally adapt and validate the WHO Safe Childbirth Checklist (SCC) in Brazilian hospitals. Methods: a methodological study was carried out with consensus techniques and cross-cultural adaptation stages. The original SCC underwent three adaptation and validation stages: 1- nominal group with a panel of experts; 2- consensus conference at two maternity schools, in meetings with professionals who would use the list; 3- pre-test with a structured questionnaire for health professionals from both maternities (n=40) after 30 days of using the checklist. Validation criteria contemplated the content validity, adequated to Brazilian protocols, terminology and feasibility for local context. Results: the adapted SCC in Brazil was called the Lista de Verificação para o Parto Seguro - Brasil (LVPS-BR) (Checklist for Safe Childbirth -Brazil) and included 49 items. In the first stage, the 29 items of the original SCC were approved with some adaptations (e.g. CD4 was replaced by the Rapid HIV Test). In the second stage, some of the 29 items were adjusted and added 24 items more. In the third stage, three items were excluded, two were grouped and one more was added. Conclusions: the validation process provided a potentially useful LVPS for the Brazilian context, presenting validity and feasibility evidences for the Brazilian context.
