Balanced crystalloid solutions versus 0.9% saline for treating acute diarrhoea and severe dehydration in children.

BACKGROUND: Although acute diarrhoea is a self-limiting disease, dehydration may occur in some children. Dehydration is the consequence of an increased loss of water and electrolytes (sodium, chloride, potassium, and bicarbonate) in liquid stools. When these losses are high and not replaced adequately, severe dehydration appears. Severe dehydration is corrected with intravenous solutions. The most frequently used solution for this purpose is 0.9% saline. Balanced solutions (e.g. Ringer's lactate) are alternatives to 0.9% saline and have been associated with fewer days of hospitalization and better biochemical outcomes. Available guidelines provide conflicting recommendations. It is unclear whether 0.9% saline or balanced intravenous fluids are most effective for rehydrating children with severe dehydration due to diarrhoea. OBJECTIVES: To evaluate the benefits and harms of balanced solutions for the rapid rehydration of children with severe dehydration due to acute diarrhoea, in terms of time in hospital and mortality compared to 0.9% saline. SEARCH METHODS: We used standard, extensive Cochrane search methods. The latest search date was 4 May 2022. SELECTION CRITERIA: We included randomized controlled trials in children with severe dehydration due to acute diarrhoea comparing balanced solutions, such as Ringer's lactate or Plasma-Lyte with 0.9% saline solution, for rapid rehydration. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes were 1. time in hospital and 2. MORTALITY: Our secondary outcomes were 3. need for additional fluids, 4. total amount of fluids received, 5. time to resolution of metabolic acidosis, 6. change in and the final values of biochemical measures (pH, bicarbonate, sodium, chloride, potassium, and creatinine), 7. incidence of acute kidney injury, and 8. ADVERSE EVENTS: We used GRADE to assess the certainty of the evidence. MAIN RESULTS: Characteristics of the included studies We included five studies with 465 children. Data for meta-analysis were available from 441 children. Four studies were conducted in low- and middle-income countries and one study in two high-income countries. Four studies evaluated Ringer's lactate, and one study evaluated Plasma-Lyte. Two studies reported the time in hospital, and only one study reported mortality as an outcome. Four studies reported final pH and five studies reported bicarbonate levels. Adverse events reported were hyponatremia and hypokalaemia in two studies each. Risk of bias All studies had at least one domain at high or unclear risk of bias. The risk of bias assessment informed the GRADE assessments. Primary outcomes Compared to 0.9% saline, the balanced solutions likely result in a slight reduction of the time in hospital (mean difference (MD) -0.35 days, 95% confidence interval (CI) -0.60 to -0.10; 2 studies; moderate-certainty evidence). However, the evidence is very uncertain about the effect of the balanced solutions on mortality during hospitalization in severely dehydrated children (risk ratio (RR) 0.33, 95% CI 0.02 to 7.39; 1 study, 22 children; very low-certainty evidence). Secondary outcomes Balanced solutions probably produce a higher increase in blood pH (MD 0.06, 95% CI 0.03 to 0.09; 4 studies, 366 children; low-certainty evidence) and bicarbonate levels (MD 2.44 mEq/L, 95% CI 0.92 to 3.97; 443 children, four studies; low-certainty evidence). Furthermore, balanced solutions likely reduces the risk of hypokalaemia after the intravenous correction (RR 0.54, 95% CI 0.31 to 0.96; 2 studies, 147 children; moderate-certainty evidence). Nonetheless, the evidence suggests that balanced solutions may result in no difference in the need for additional intravenous fluids after the initial correction; in the amount of fluids administered; or in the mean change of sodium, chloride, potassium, and creatinine levels. AUTHORS' CONCLUSIONS: The evidence is very uncertain about the effect of balanced solutions on mortality during hospitalization in severely dehydrated children. However, balanced solutions likely result in a slight reduction of the time in the hospital compared to 0.9% saline. Also, balanced solutions likely reduce the risk of hypokalaemia after intravenous correction. Furthermore, the evidence suggests that balanced solutions compared to 0.9% saline probably produce no changes in the need for additional intravenous fluids or in other biochemical measures such as sodium, chloride, potassium, and creatinine levels. Last, there may be no difference between balanced solutions and 0.9% saline in the incidence of hyponatraemia.

Prophylactic corticosteroids for paediatric heart surgery with cardiopulmonary bypass.

BACKGROUND: Corticosteroids are routinely given to children undergoing cardiac surgery with cardiopulmonary bypass (CPB) in an attempt to ameliorate the inflammatory response. Their use is still controversial and the decision to administer the intervention can vary by centre and/or by individual doctors within that centre. OBJECTIVES: This review is designed to assess the benefits and harms of prophylactic corticosteroids in children between birth and 18 years of age undergoing cardiac surgery with CPB. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase and Conference Proceedings Citation Index-Science in June 2020. We also searched four clinical trials registers and conducted backward and forward citation searching of relevant articles. SELECTION CRITERIA: We included studies of prophylactic administration of corticosteroids, including single and multiple doses, and all types of corticosteroids administered via any route and at any time-point in the perioperative period. We excluded studies if steroids were administered therapeutically. We included individually randomised controlled trials (RCTs), with two or more groups (e.g. multi-drug or dose comparisons with a control group) but not 'head-to-head' trials without a placebo or a group that did not receive corticosteroids. We included studies in children, from birth up to 18 years of age, including preterm infants, undergoing cardiac surgery with the use of CPB. We also excluded studies in patients undergoing heart or lung transplantation, or both; studies in patients already receiving corticosteroids; in patients with abnormalities of the hypothalamic-pituitary-adrenal axis; and in patients given steroids at the time of cardiac surgery for indications other than cardiac surgery. DATA COLLECTION AND ANALYSIS: We used the Covidence systematic review manager to extract and manage data for the review. Two review authors independently assessed studies for inclusion, extracted data, and assessed risks of bias. We resolved disagreements by consensus or by consultation with a third review author. We assessed the certainty of evidence with GRADE. MAIN RESULTS: We found 3748 studies, of which 888 were duplicate records. Two studies had the same clinical trial registration number, but reported different populations and interventions. We therefore included them as separate studies. We screened titles and abstracts of 2868 records and reviewed full text reports for 84 studies to determine eligibility. We extracted data for 13 studies. Pooled analyses are based on eight studies. We reported the remaining five studies narratively due to zero events for both intervention and placebo in the outcomes of interest. Therefore, the final meta-analysis included eight studies with a combined population of 478 participants. There was a low or unclear risk of bias across the domains. There was moderate certainty of evidence that corticosteroids do not change the risk of in-hospital mortality (five RCTs; 313 participants; risk ratio (RR) 0.83, 95% confidence interval (CI) 0.33 to 2.07) for children undergoing cardiac surgery with CPB. There was high certainty of evidence that corticosteroids reduce the duration of mechanical ventilation (six RCTs; 421 participants; mean difference (MD) 11.37 hours lower, 95% CI -20.29 to -2.45) after the surgery. There was high-certainty evidence that the intervention probably made little to no difference to the length of postoperative intensive care unit (ICU) stay (six RCTs; 421 participants; MD 0.28 days lower, 95% CI -0.79 to 0.24) and moderate-certainty evidence that the intervention probably made little to no difference to the length of the postoperative hospital stay (one RCT; 176 participants; mean length of stay 22 days; MD -0.70 days, 95% CI -2.62 to 1.22). There was moderate certainty of evidence for no effect of the intervention on all-cause mortality at the longest follow-up (five RCTs; 313 participants; RR 0.83, 95% CI 0.33 to 2.07) or cardiovascular mortality at the longest follow-up (three RCTs; 109 participants; RR 0.40, 95% CI 0.07 to 2.46). There was low certainty of evidence that corticosteroids probably make little to no difference to children separating from CPB (one RCT; 40 participants; RR 0.20, 95% CI 0.01 to 3.92). We were unable to report information regarding adverse events of the intervention due to the heterogeneity of reporting of outcomes. We downgraded the certainty of evidence for several reasons, including imprecision due to small sample sizes, a single study providing data for an individual outcome, the inclusion of both appreciable benefit and harm in the confidence interval, and publication bias. AUTHORS' CONCLUSIONS: Corticosteroids  probably do not change the risk of mortality for children having heart surgery using CPB at any time point. They probably reduce the duration of postoperative ventilation in this context, but have little or no effect on the total length of postoperative ICU stay or total postoperative hospital stay. There was inconsistency in the adverse event outcomes reported which, consequently, could not be pooled. It is therefore impossible to provide any implications and policy-makers will be unable to make any recommendations for practice without evidence about adverse effects. The review highlighted the need for well-conducted RCTs powered for clinical outcomes to confirm or refute the effect of corticosteroids versus placebo in children having cardiac surgery with CPB. A core outcome set for adverse event reporting in the paediatric major surgery and intensive care setting is required.

Smectite for acute infectious diarrhoea in children.

BACKGROUND: As mortality secondary to acute infectious diarrhoea has decreased worldwide, the focus shifts to adjuvant therapies to lessen the burden of disease. Smectite, a medicinal clay, could offer a complementary intervention to reduce the duration of diarrhoea. OBJECTIVES: To assess the effects of smectite for treating acute infectious diarrhoea in children. SEARCH METHODS: We searched the Cochrane Infectious Diseases Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Pubmed), Embase (Ovid), LILACS, reference lists from studies and previous reviews, and conference abstracts, up to 27 June 2017. SELECTION CRITERIA: Randomized and quasi-randomized trials comparing smectite to a control group in children aged one month to 18 years old with acute infectious diarrhoea. DATA COLLECTION AND ANALYSIS: Two review authors independently screened abstracts and the full texts for inclusion, extracted data, and assessed risk of bias. Our primary outcomes were duration of diarrhoea and clinical resolution at day 3. We summarized continuous outcomes using mean differences (MD) and dichotomous outcomes using risk ratios (RR), with 95% confidence intervals (CI). Where appropriate, we pooled data in meta-analyses and assessed heterogeneity. We explored publication bias using a funnel plot. MAIN RESULTS: Eighteen trials with 2616 children met our inclusion criteria. Studies were conducted in both ambulatory and in-hospital settings, and in both high-income and low- or middle-income countries. Most studies included children with rotavirus infections, and half included breastfed children.Smectite may reduce the duration of diarrhoea by approximately a day (MD -24.38 hours, 95% CI -30.91 to -17.85; 14 studies; 2209 children; low-certainty evidence); may increase clinical resolution at day 3 (risk ratio (RR) 2.10, 95% CI 1.30 to 3.39; 5 trials; 312 children; low-certainty evidence); and may reduce stool output (MD -11.37, 95% CI -21.94 to -0.79; 3 studies; 634 children; low-certainty evidence).We are uncertain whether smectite reduces stool frequency, measured as depositions per day (MD -1.33, 95% CI -2.28 to -0.38; 3 studies; 954 children; very low-certainty evidence). There was no evidence of an effect on need for hospitalization (RR 0.93, 95% CI 0.75 to 1.15; 2 studies; 885 children; low-certainty evidence) and need for intravenous rehydration (RR 0.77, 95% CI 0.54 to 1.11; 1 study; 81 children; moderate-certainty evidence). The most frequently reported side effect was constipation, which did not differ between groups (RR 4.71, 95% CI 0.56 to 39.19; 2 studies; 128 children; low-certainty evidence). No deaths or serious adverse effects were reported. AUTHORS' CONCLUSIONS: Based on low-certainty evidence, smectite used as an adjuvant to rehydration therapy may reduce the duration of diarrhoea in children with acute infectious diarrhoea by a day; may increase cure rate by day 3; and may reduce stool output, but has no effect on hospitalization rates or need for intravenous therapy.

Validación de un cuestionario para medir la habilidad de la población general para evaluar afirmaciones acerca de tratamientos médicos.

INTRODUCCIÓN: Todos los días, las personas se enfrentan a afirmaciones acerca de tratamientos en medios de comunicación, redes sociales o por viva voz. OBJETIVO: Validar un cuestionario en español para medir las habilidades de un individuo para evaluar afirmaciones acerca de tratamientos. MÉTODO: Veintidós preguntas de opción múltiple de la base de datos Claim Evaluation Tools fueron traducidas y aplicadas a 172 niños y 268 adultos. Mediante un modelo Rasch se exploró el ajuste promedio e individual por reactivo, el potencial comportamiento diferencial del reactivo (basado en el género, edad y modo de aplicación), la multidimensionalidad y la independencia local. RESULTADOS: El ajuste promedio por reactivo fue apropiado. Cuatro preguntas de opción múltiple mostraron pobre ajuste. La fiabilidad del cuestionario fue satisfactoria, con un índice de separación de 0.7. Las preguntas de opción múltiple fueron unidimensionales, y no hubo dependencia específica. CONCLUSIÓN: Se obtuvo un conjunto de 18 preguntas de opción múltiple con ajuste satisfactorio. El cuestionario es el primero disponible y validado en español para medir las habilidades de los individuos para evaluar afirmaciones acerca de tratamientos. INTRODUCTION: Every day, people are faced with claims about treatment effects through mass media, social media, or by word of mouth. OBJECTIVE: To validate a Spanish-language questionnaire to measure the ability of an individual to assess claims about treatments effects. METHOD: A set of 22 multiple choice questions taken from the claim evaluation tools database were translated and applied to 172 children and 268 adults. Using a Rasch model, overall and individual item-person fit was explored, as well as the potential item differential functioning (based on gender, age and mode of administration), multidimensionality and local independence. RESULTS: Overall item-person fit was appropriate. Four multiple-choice questions showed a poor fit. Reliability of the questionnaire was satisfactory with a person separation index of 0.7. Multiple-choice questions were unidimensional, and there was no specific dependency. CONCLUSION: A set of 18 multiple-choice questions with satisfactory fit was obtained. This is the first available questionnaire validated in Spanish to measure individuals' ability to assess claims about treatment effects.

Methods proposed for monitoring the implementation of evidence-based research: a cross-sectional study.

OBJECTIVES: Evidence-based research (EBR) is the systematic and transparent use of prior research to inform a new study so that it answers questions that matter in a valid, efficient, and accessible manner. This study surveyed experts about existing (e.g., citation analysis) and new methods for monitoring EBR and collected ideas about implementing these methods. STUDY DESIGN AND SETTING: We conducted a cross-sectional study via an online survey between November 2022 and March 2023. Participants were experts from the fields of evidence synthesis and research methodology in health research. Open-ended questions were coded by recurring themes; descriptive statistics were used for quantitative questions. RESULTS: Twenty-eight expert participants suggested that citation analysis should be supplemented with content evaluation (not just what is cited but also in which context), content expert involvement, and assessment of the quality of cited systematic reviews. They also suggested that citation analysis could be facilitated with automation tools. They emphasized that EBR monitoring should be conducted by ethics committees and funding bodies before the research starts. Challenges identified for EBR implementation monitoring were resource constraints and clarity on responsibility for EBR monitoring. CONCLUSION: Ideas proposed in this study for monitoring the implementation of EBR can be used to refine methods and define responsibility but should be further explored in terms of feasibility and acceptability. Different methods may be needed to determine if the use of EBR is improving over time.

Treating BCG-induced disease in children.

BACKGROUND: Bacillus Calmette-Guerín (BCG) is a live attenuated vaccine to prevent tuberculosis, routinely administered at birth as part of the World Health Organization global expanded immunisation programme. Given intradermally, it can cause adverse reactions, including local, regional, distant and disseminated manifestations that may cause parental distress. Rarely, it can cause serious illness and even death. Among those patients with immunocompromised conditions, such as the human immunodeficiency virus (HIV) infection, the complication rate is even higher. OBJECTIVES: To assess the effects of different interventions for treating BCG-induced disease in children. SEARCH METHODS: The following databases were searched: the Cochrane Infectious Diseases Group Specialized Register and Cochrane Central Register of Controlled Trials (CENTRAL), published in The Cochrane Library (The Cochrane Library 2012, Issue 4); MEDLINE (1966 to November 2012); EMBASE (1947 to November 2012); and LILACS (1980 to November 2012). The metaRegister of Controlled Trials (mRCT) and the WHO trials search portal. Conference proceedings for relevant abstracts and experts were also contacted to identify studies. No language restrictions were applied. SELECTION CRITERIA: Randomized controlled trials (RCTs) comparing any medical or surgical treatment modality for BCG-induced disease in children. DATA COLLECTION AND ANALYSIS: Two authors independently evaluated titles, applied inclusion criteria, and assessed the risk of bias of studies. The primary outcomes were the failure rate of therapies for all types of BCG vaccine-induced complications and the time to resolution of illness measured in months. The secondary outcomes were death from BCG vaccine-induced disease and the all-cause mortality. Risk ratios (RRs) were used as measure of effect for dichotomous outcomes and mean differences for continuous outcomes. MAIN RESULTS: Five RCTs analysing 341 children addressed the primary outcomes and were included. Four arms compared oral antibiotics to no intervention or placebo, one arm evaluated needle aspiration compared to no intervention, and another evaluated the use of locally instilled isoniazid versus oral erythromycin.Two small studies evaluated oral isoniazid; we are uncertain of whether this intervention has an effect on clinical failure (RR 1.48; 95% Confidence Interval (CI) 0.79 to 2.78; 54 participants, two studies, very low quality evidence). Similarly, for oral erythromycin, we are uncertain if there is an effect (clinical failure RR 1.03; 95% CI 0.70 to 1.53; 148 participants, three studies, very low quality evidence), and for oral isoniazid plus rifampicin (clinical failure, RR 1.20; 95% CI 0.51 to 2.83; 35 participants, one study, very low quality evidence).In patients with lymphadenitis abscess, needle aspiration may reduce clinically persistent BCG-induced disease at 6 to 9 months of follow-up (RR 0.13; 95% CI 0.03 to 0.55; 77 participants, one study, low quality evidence). In another study of patients with the same condition, aspiration plus local instillation of isoniazid reduces time to clinical cure compared to aspiration plus oral erythromycin (mean difference 1.49 months less; 95% CI 0.82 to 2.15 less; 27 participants, one study).No RCTs of HIV-infected infants with a BCG-induced disease evaluated the use of antibiotics or other therapies for reducing the rate of clinical failure or the time to clinical resolution. No data on mortality secondary to the interventions for treating BCG-induced disease were reported. AUTHORS' CONCLUSIONS: It is unclear if oral antibiotics (isoniazid, erythromycin, or a combination of isoniazid plus rifampicin) are effective for the resolution of BCG-induced disease. Most non-suppurated lymphadenitis will resolve without treatment in 4 to 6 months. Patients with lymphadenitis abscess might benefit from needle aspiration and possibly local instillation of isoniazid could shorten recovery time. Included studies were generally small and could be better conducted. Further research should evaluate the use of needle aspiration and local instillation of isoniazid in fluctuant nodes. Therapeutic and preventive measures in HIV-infected infants could be important given the higher risk of negative outcomes in this group.

Piloting the informed health choices resources in Barcelona primary schools: A mixed methods study.

INTRODUCTION: The main objective of the Informed Health Choices (IHC) project is to teach people to assess treatment claims and make informed health choices. For this purpose, the IHC learning resources were developed for primary school children. The aim of this study is to explore students' and teachers' experience when using the IHC resources in primary schools in Barcelona (Spain). METHODS: We conducted a mixed methods study for piloting the IHC resources in a convenience sample of primary schools in Barcelona. The intervention included a workshop with teachers, and nine lessons with students. We collected data using multiple approaches. We performed quantitative and qualitative analyses, and integrated the findings in a joint display. Finally, we formulated recommendations for using the IHC resources in this setting. RESULTS: Two schools, with a total of 143 students in 4th and 5th grade and six teachers, participated in the study. One school followed the suggested IHC teaching plan and competed all the lessons; the other school modified the plan substantially and did not complete all the lessons. Overall, students and teachers from both schools understood, were interested in, and were able to apply the content of the lessons. During the lessons, the textbook was useful for students; nevertheless, for the teachers, the usefulness of the IHC resources was variable. Teachers adapted the IHC resources to increase student participation and used Information and Communications Technologies tools. We observed more facilitators than barriers to teach the lessons. The teachers suggested some ideas to improve the lessons based on activities they developed and implemented. The integration analysis showed great convergence of the quantitative and qualitative findings. We propose seven recommendations for using the IHC resources in this setting. CONCLUSIONS: Students and teachers from primary schools in Barcelona showed a positive experience when using IHC resources; however, these resources should be adapted to promote classroom participation.

A Case Report of Guillain-Barre Syndrome in an Eleven-Month Infant.

Guillain-Barre syndrome (GBS) is an acute immune-mediated progressive predominantly motor symmetric polyradiculoneuropathy which causes demyelination and leads to weakness, ataxia and areflexia. There are a variety of forms of the syndrome; and despite being the most common cause of acute flaccid paralysis in children, it has a low incidence under 18 years old, and it is even rarer in children less than 2 years of age. Very few cases have been reported under 12 months of age. We describe a case of an 11-month-old male infant presenting with weakness and inability to ambulate who was diagnosed with GBS.

Clinical and epidemiological characteristics of children with SARS-CoV-2 infection: a case series in Sinaloa.

Background: The SARS-CoV-2 virus may affect both adults and children. Although COVID-19 has a lower prevalence in infancy and has been described as mild, the clinical characteristics may vary, and there is a possibility of complications. The objectives of this study were to describe the clinical and epidemiological aspects of confirmed COVID-19 pediatric cases in the state of Sinaloa, Mexico, during the first 3 months of the pandemic, and children admitted with COVID-19 to a secondary hospital. Methods: This case series includes all patients with SARS-CoV-2 infection confirmed by PCR (polymerase chain reaction) test, identified in the state epidemiological surveillance system (SISVER) between March 1 and May 31, 2020. Confirmed patients admitted to the Sinaloa Pediatric Hospital (HPS) in the same period are also described. Results: Fifty-one children with SARS-CoV-2 were included, of which ten were admitted to the HPS. The median age was 10 years. The more frequent symptoms were fever (78%), cough (67%), and headache (57%). Most cases were mild or asymptomatic. Three patients with comorbidities died. Only four of ten patients identified in HPS were admitted with the diagnosis of possible COVID-19. Conclusions: SARS-CoV-2 infection in children was mostly mild or asymptomatic, and the clinical presentation varied. There is a possibility of complications, especially in children with comorbidities.

Introducción: El SARS-CoV-2 puede afectar tanto a adultos como a niños. Aunque la COVID-19 presenta menor prevalencia en la infancia y se ha descrito como leve, las características clínicas pueden ser variables y existe la posibilidad de complicaciones. Los objetivos de este estudio fueron describir las características clínicas y epidemiológicas de los casos pediátricos confirmados en el Estado de Sinaloa, México, durante los primeros 3 meses de la pandemia, y de los niños con COVID-19 internados en un hospital de segundo nivel. Métodos: Esta serie de casos incluyó pacientes con infección por SARS-CoV-2 confirmados por prueba de reacción en cadena de la polimerasa (PCR), identificados en el Sistema de Vigilancia Epidemiológica de Enfermedades Respiratorias (SISVER) del 1 de marzo al 31 de mayo de 2020. Se describen también las características de todos los niños confirmados en el Hospital Pediátrico de Sinaloa (HPS) en las mismas fechas. Resultados: Se incluyeron 51 niños con infección por SARS-CoV-2, de los cuales 10 fueron internados en el HPS. La mediana de edad fue de 10 años. Los síntomas más frecuentes fueron fiebre (78%), tos (67%) y cefalea (57%). La mayoría de los casos fueron leves o asintomáticos. Tres pacientes con comorbilidad fallecieron. Solo cuatro de diez pacientes identificados en el HPS ingresaron bajo sospecha de COVID-19. Conclusiones: La infección por SARS-CoV-2 en los niños fue, en su mayoría, asintomática o leve, y la presentación fue variable. Existe la posibilidad de que se produzcan complicaciones, principalmente en niños con comorbilidad.

Methodological assessment of Mexican Clinical Practice Guidelines: GRADE framework adherence and critical appraisal.

BACKGROUND AND OBJECTIVE: Clinical Practice Guidelines (CPGs) provide evidence-based recommendations to healthcare professionals, policy makers, patients and other stakeholders. Mexico is the biggest producer of CPGs in Latin America and Caribbean countries. The National Healthcare Technology Excellence Center (acronym in Spanish: CENETEC) is responsible for the CPG development, adaptation and update. The aim of this study was to assess the adherence to the GRADE framework and to critically appraise the Mexican CPGs with the AGREE-II tool. STUDY DESIGN: We conducted a descriptive cross-sectional study with a random sample of 86 CPGs produced by CENETEC between 2015 and 2017 and published in an online database called "Catalogo Maestro". We assessed the adherence to the GRADE framework and performed a critical appraisal with the AGREE II tool. RESULTS: Of the 86 CPGs, 34 were published in 2015, 21 in 2016 and 31 in 2017. Of the 86 CPGs, 25 (29%) used the GRADE framework; adherence to GRADE standards was, however, inconsistent and generally poor. The overall methodological quality by AGREE II proved a median of 16.6% (Min 16.6%, Max 50%). CONCLUSION: CPGs produced by CENETEC during this period had a poor adherence to the GRADE framework and low score by AGREE II standards. A concerted initiative could rapidly improve CENETEC guidelines.

Quality of information in news media reports about the effects of health interventions: Systematic review and meta-analyses.

Background Many studies have assessed the quality of news reports about the effects of health interventions, but there has been no systematic review of such studies or meta-analysis of their results. We aimed to fill this gap (PROSPERO ID: CRD42018095032). Methods We included studies that used at least one explicit, prespecified and generic criterion to assess the quality of news reports in print, broadcast, or online news media, and specified the sampling frame, and the selection criteria and technique. We assessed criteria individually for inclusion in the meta-analyses, excluding ineligible criteria and criteria with inadequately reported results. We mapped and grouped criteria to facilitate evidence synthesis. Where possible, we extracted the proportion of news reports meeting the included criterion. We performed meta-analyses using a random effects model to estimate such proportions for individual criteria and some criteria groups, and to characterise heterogeneity across studies.  Results We included 44 primary studies in the review, and 18 studies and 108 quality criteria in the meta-analyses. Many news reports gave an unbalanced and oversimplified picture of the potential consequences of interventions. A limited number mention or adequately address conflicts of interest (22%; 95% CI 7%-49%) (low certainty), alternative interventions (36%; 95% CI 26%-47%) (moderate certainty), potential harms (40%; 95% CI 23%-61%) (low certainty), or costs (18%; 95% CI 12%-28%) (moderate certainty), or quantify effects (53%; 95% CI 36%-69%) (low certainty) or report absolute effects (17%; 95% CI 4%-49%) (low certainty).  Discussion There is room for improving health news, but it is logically more important to improve the public's ability to critically appraise health information and make judgements for themselves.

COVID-19 Vaccines Safety Tracking (CoVaST): Protocol of a Multi-Center Prospective Cohort Study for Active Surveillance of COVID-19 Vaccines' Side Effects.

BACKGROUND: Coronavirus disease (COVID-19) vaccine-related side effects have a determinant role in the public decision regarding vaccination. Therefore, this study has been designed to actively monitor the safety and effectiveness of COVID-19 vaccines globally. METHODS: A multi-country, three-phase study including a cross-sectional survey to test for the short-term side effects of COVID-19 vaccines among target population groups. In the second phase, we will monitor the booster doses' side effects, while in the third phase, the long-term safety and effectiveness will be investigated. A validated, self-administered questionnaire will be used to collect data from the target population; Results: The study protocol has been registered at ClinicalTrials.gov, with the identifier NCT04834869. CONCLUSIONS: CoVaST is the first independent study aiming to monitor the side effects of COVID-19 vaccines following booster doses, and the long-term safety and effectiveness of said vaccines.
