Impact of exergames on bmi and cardiovascular risk factors: a systematic review / Impacto de exergames sobre imc y los factores de riesgo cardiovascular: revisión sistemática / Impacto de exergames no imc e fatores de risco cardiovascular: uma revisão sistemática

ABSTRACT Introduction: Exergames or active video games are digital platforms with functionality associated with body movement, which dialogue with improving physical activity levels, stimulating pleasure in practice and adherence to change habits, physically active behavior, and better quality of life. Objective: This study aimed to synthesize the available evidence on the contribution of exergame to Body Mass Index, physical activity level, glycemic control, blood pressure, and cardiorespiratory fitness in adolescents. Methods: This is a systematic review, reported following the PRISMA writing recommendations, without language restrictions, for articles indexed in the following databases: MEDLINE / PubMed, Embase, Cochrane Library, and Lilacs. Data extraction was performed analogously in a spreadsheet previously tested and standardized. The assessment of the risk of bias in the included studies was carried out by the RoB 1.0 tool in all of its domains in duplicate of reviewers. Initially, 3.039 studies were found. Results: The studies cover a total of 526 adolescents aged ten to 19. The most used platform in the studies was the Nintendo Wii, followed by the PlayStation, Xbox 360, and Dance Dance Revolution. The results indicated that interventions using exergames were effective for changing BMI, but there was no evidence on cardiovascular outcomes, with no effective changes in glycemic control and blood pressure and a significant response (p <0.05) in cardiorespiratory fitness. Conclusion: The exergame points to satisfactory results in improving health and can be incorporated as a relevant public policy in the adolescent health promotion.

Thiazide diuretics alone or combined with potassium-sparing diuretics to treat hypertension: a systematic review and network meta-analysis of randomized controlled trials.

BACKGROUND: The magnitude of blood pressure (BP)-lowering effects and decrease of the adverse effects of thiazide diuretics provided by potassium-sparing diuretics remain uncertain. The aim of this study was to compare the BP-lowering efficacy and the incidence of adverse effects of high (T+) and low-dose (T-) thiazide diuretics, alone or combined with high (PS+) or low-dose (PS-) potassium-sparing diuretics in patients with primary hypertension. METHODS: A systematic literature search was performed in PubMed/MEDLINE, the Cochrane Central Register of Controlled Trials, Embase, Web of Science, Scopus and LILACS. Randomized double-blind placebo or active-controlled trials (RCT) with 3 weeks to 1 year of follow-up were included. Sample size, mean and standard deviation from baseline, follow-up and change from baseline values were extracted by two independent reviewers. Pairwise random effect models and Bayesian network meta-analysis models were used to compare the effects of treatments. The risk of bias in individual studies was assessed using the Rob 1.0 tool. The primary outcome was the mean difference in office SBP. Secondary outcomes were the mean difference in biochemical parameters and the incidence of nonmelanoma skin cancer. RESULTS: Two hundred and seventy-six double-blind RCTs involving 58 807 participants (mean age: 55 years; 45% women) were included. All treatment groups were more effective than placebo in lowering BP, with mean differences (MDs) of change from baseline ranging from -7.66 mmHg [95% credible interval (95% CrI), -8.53 to -6.79] for T- to -12.77 mmHg (95% CrI, -15.22 to -10.31) for T+PS-. T+ alone or combined with potassium-sparing was more effective in reducing BP than T-. The surface under the cumulative ranking curve (SUCRA) estimated ranking showed that the best effectiveness in lowering SBP was found for T+PS- (0.69), T+PS+ (0.65) and T+ (0.54). Compared with placebo, all treatments (except T-PS-) were associated with more potassium reduction and T+ compared with all other treatments and T- when compared with T-PS-. Compared with placebo, all active treatments (except T+PS+) showed higher elevations of uric acid. The increase of plasma glucose promoted by thiazides alone was reduced by potassium-sparing agents. CONCLUSION: Thiazides with potassium-sparing diuretics are associated with increased BP-lowering efficacy compared with thiazides alone while minimizing hypokalaemia and hyperglycaemia. These findings demonstrate that thiazide and potassium-sparing diuretic combination is preferable to thiazide alone in treating hypertension.

Developing and validating a machine learning ensemble model to predict postoperative delirium in a cohort of high-risk surgical patients: A secondary cohort analysis.

BACKGROUND: Postoperative delirium (POD) has a negative impact on prognosis, length of stay and the burden of care. Although its prediction and identification may improve postoperative care, this need is largely unmet in the Brazilian public health system. OBJECTIVE: To develop and validate a machine-learning prediction model and estimate the incidence of delirium. We hypothesised that an ensemble machine-learning prediction model that incorporates predisposing and precipitating features could accurately predict POD. DESIGN: A secondary analysis nested in a cohort of high-risk surgical patients. SETTING: An 800-bed, quaternary university-affiliated teaching hospital in Southern Brazil. We included patients operated on from September 2015 to February 2020. PATIENTS: We recruited 1453 inpatients with an all-cause postoperative 30-day mortality risk greater than 5% assessed preoperatively by the ExCare Model. MAIN OUTCOME MEASURE: The incidence of POD classified by the Confusion Assessment Method, up to 7 days postoperatively. Predictive model performance with different feature scenarios were compared with the area under the receiver operating characteristic curve. RESULTS: The cumulative incidence of delirium was 117, giving an absolute risk of 8.05/100 patients. We developed multiple machine-learning nested cross-validated ensemble models. We selected features through partial dependence plot analysis and theoretical framework. We treated the class imbalance with undersampling. Different feature scenarios included: 52 preoperative, 60 postoperative and only three features (age, preoperative length of stay and the number of postoperative complications). The mean areas (95% confidence interval) under the curve ranged from 0.61 (0.59 to 0.63) to 0.74 (0.73 to 0.75). CONCLUSION: A predictive model composed of three indicative readily available features performed better than those with numerous perioperative features, pointing to its feasibility as a prognostic tool for POD. Further research is required to test the generalisability of this model.

Peak Cardiac Output Determined Using Inert Gas Rebreathing: A Comparison of Two Exercise Protocols.

PURPOSE: This study aimed to compare Q˙peak elicited by a constant load protocol ( Q˙CL ) and an incremental step protocol ( Q˙step ). METHODS: A noninferiority randomized crossover trial was used to compare Q˙peak between protocols using a noninferiority margin of 0.5 L·min -1 . Participants ( n = 34 (19 female, 15 male); 25 ± 5 yr) performed two baseline V̇O 2peak tests to determine peak heart rate (HR peak ) and peak work rate ( Wpeak ). Participants then performed the Q˙CL and Q˙step protocols each on two separate occasions with the order of the four visits randomized. Q˙peak was measured using IGR (Innocor; COSMED, Rome, Italy). The Q˙CL protocol involved a V̇O 2peak test followed 10 min later by cycling at 90% Wpeak , with IGR initiated after 2 min. Q˙step involved an incremental step test with IGR initiated when the participant's HR reached 5 bpm below their HR peak . The first Q˙CL and Q˙step tests were compared for noninferiority, and the second series of tests was used to measure repeatability (typical error (TE)). RESULTS: The Q˙CL protocol was noninferior to Q˙step ( Q˙CL = 17.1 ± 3.2, Q˙step = 16.8 ± 3.1 L·min -1 ; 95% confidence intervals, -0.16 to 0.72 L·min -1 ). The baseline V̇O 2peak (3.13 ± 0.83 L·min -1 ) was achieved during Q˙CL (3.12 ± 0.72, P = 0.87) and Q˙step (3.12 ± 0.80, P = 0.82). The TE values for Q˙peak were 6.6% and 8.3% for Q˙CL and Q˙step , respectively. CONCLUSIONS: The Q˙CL protocol was noninferior to Q˙step and may be more convenient because of the reduced time commitment to perform the measurement.

Hemostasis control after femoral percutaneous approach: A systematic review and meta-analysis.

BACKGROUND: Hemostasis control after percutaneous endovascular procedures through the femoral approach remains challenging for catheterization laboratory nurses, given method variability. OBJECTIVE: To summarize the available evidence on vascular devices efficacy dedicated to hemostasis control compared to the extrinsic compression after percutaneous procedures in the femoral vein or artery. METHODS: A systematic review with meta-analysis of randomized clinical trials was conducted. We compared different hemostasis methods in adult patients who underwent diagnostic and/or therapeutic procedures through femoral access. The databases searched were PubMed, Embase, CINAHL and Cochrane CENTRAL, and updated on 03/2022. The outcomes included hematoma, pseudoaneurysm, bleeding, minor and major vascular complication, time to hemostasis, device failure, and manual compression repetition. The risk of bias was assessed using the Cochrane Risk of Bias Tool 1.0. Pooled effect sizes on continuous, categorical and proportion variables were estimated with the random effects model. The continuous variables were summarized as the difference between means weighted by the inverse of variance (WMD), and the categorical ones by the summary of relative risks (RR), estimated by the DerSimonian and Laird method. The Freeman-Tukey method was used to estimate the summary effect of proportions. RESULTS: Fifty articles were included in the systematic review. When compared to extrinsic compression, vascular closure devices resulted in a relative risk reduction (RRR) for hematoma: RR 0.82 [95%CI 0.72 to 0.94] and in shorter time to hemostasis WMD -15.06 min [95%CI -17.56 to -12.56]; no association was observed between interventions with vascular closure devices and extrinsic compression for pseudoaneurysm, bleeding, minor and major vascular complications. Compared to extrinsic compression, sealant or gel type devices were compatible with a RRR for hematoma: RR 0.73 [95%CI 0.59 to 0.90]; and metal clip or staple type devices for pseudoaneurysm: RR 0.48 [95%CI 0.25 to 0.90]; and major vascular complication: RR 0.33 [95%CI 0.17 to 0.64]. For each 100 observations, the device failure rate for metal clip or staple was 3.28% [95%CI 1.69 to 6.27]; for suture 6.84% [95%CI 4.93 to 9.41]; for collagen 3.15% [95%CI 2.24 to 4.41]; and for sealant or gel 7.22% [95% CI 5.49 to 9.45]. CONCLUSIONS: Vascular closure devices performed better in hemostasis control. The certainty of the evidence was rated as very low to moderate. REGISTRATION: PROSPERO CRD42019140794.

Correlates of functional physical capacity in physically active older adults: a conceptual-framework-based cross-sectional analysis of social determinants of health and clinical parameters.

BACKGROUND: Functional decline in older adults may be affected by clinical status, physical fitness, and social determinants of health. AIMS: This study aimed to explore social determinants of health and health/clinical determinants on two outcomes of functional physical capacity. METHODS AND RESULTS: Therefore, a population-based sample of 327 older adults (69 ± 7 years; 83.5% women) underwent demographical and clinical questionnaires, risk factors assessments, 6-min walk testing (walking capacity), and handgrip strength testing. Based on multivariable linear regression models, age ( - 4.05 m; - 5.3 to - 2.8), being men (71.40 m; 50.5-92.3), body mass index ( - 3.88 m; - 5.6 to - 2.1), and quality of life (18.48 m; 6.3-30.6) remained as predictive variables for walking capacity (R2 = 30.8%). In the final model for handgrip strength, age ( - 0.6% kgf; 0.89-0.2) and male sex (65.2% kgf; 55.3-75.8) remained as predictive variables. DISCUSSION: The mean values for our predicted outcomes were similar to those of healthy and physically active ones, which may be a consequence of the engagement of our sample in a lifestyle program. Also, although using the conceptual framework model to choose explanatory variables with a solid rationale, some of them may present reverse causality in this study setting, regardless of our efforts to annulate this type of bias. CONCLUSIONS: Despite exploratory analyses including contextual factors as potential predictors of walking capacity and handgrip strength, only outcomes at the individual levels were associated, either positively or negatively, with the variations presented by this studied sample of older adults.

Capacity Building in Peer-review: A Student-Led Journal Report.

Peer-review optimizes the quality of research articles; however, new strategies need to be implemented to enhance peer-review capacity. This report comprises the peer-review process of a medical student-led journal editorial board, detailing its challenges and the students' role. The peer education approach conducted a capacity-building activity, developing guidelines, and practicing critical appraisal and constructive feedback in manners that classroom research training cannot. Understandings of an effective peer-review brought to discussion from standardization and blinding to ethical and scientific competencies essential in researchers. All parties, including students, should be allowed to extend their capabilities to enhance scholarly publishing.

Are the recommendation of sodium and fluid restriction in heart failure patients changing over the past years? A systematic review and meta-analysis.

BACKGROUND: Heart failure (HF) is a growing problem for healthcare systems worldwide. Sodium and fluid restriction are non-pharmacological treatments recommended for patients with HF by several guidelines over the years, even without consensus. OBJECTIVE: To evaluate the effects of sodium and fluid restriction in patients with HF. METHODS: We searched MEDLINE, Embase, and Cochrane CENTRAL databases up to June 2020 and screened the reference lists of relevant articles. We included randomized controlled trials evaluating sodium and/or fluid restriction in patients with HF. We assessed three independent comparisons: (a) sodium restriction versus control; (b) fluid restriction versus control; and (c) sodium and fluid restriction versus control. Main outcomes of interest were all-cause mortality and hospitalization. Two independent reviewers selected studies and extracted data. We pooled the results using random-effects meta-analysis. We used the RoB 2.0 and the GRADE framework to assess risk of bias and quality of evidence. RESULTS: We included 16 studies totaling 3545 patients in our meta-analysis. Daily sodium intake was 1.5-2.4 g for the intervention group and >2.7 g for the control group, and daily fluid intake was 0.8-1.5 L for the intervention group and free oral fluid intake for the control group. Sodium restriction increased mortality (relative risk 1.92, 95% confidence interval 1.51 to 2.45, moderate quality of evidence) and hospitalization (relative risk 1.63, 1.11 to 2.40, low quality of evidence). Fluid restriction reduced mortality (relative risk 0.32, 0.13 to 0.82, low quality of evidence) and hospitalization (relative risk 0.46, 0.27 to 0.77, n = 331, low quality of evidence). The combination of sodium and fluid restriction did not significantly affect the risk of mortality (relative risk 0.92, 0.49 to 1.73, low quality of evidence) or the risk of hospitalization (relative risk 0.94, 0.75 to 1.19, low quality of evidence). CONCLUSION: The combination of sodium and fluid restriction in clinical trials resulted in a null effect although results in the opposite direction were observed for each intervention independently. Combined sodium and fluid restriction are usually recommended for patients with HF. Our findings of sodium restriction harm, risk of mortality and hospitalization are consistent with publications from several clinical trial and physiologic explanations. A well-designed clinical trial nested by an implementation study is urgent for definitive sodium range recommendation, specially considering the change of currently guidelines, pushing up the cut-off of sodium restriction range.

Thiazide diuretics alone or in combination with a potassium-sparing diuretic on blood pressure-lowering in patients with primary hypertension: protocol for a systematic review and network meta-analysis.

BACKGROUND: The use of thiazide (T) diuretics for the treatment of hypertension may be associated with adverse metabolic effects, which can be minimized by combining thiazides with potassium-sparing (PS) diuretics. The additional blood pressure (BP)-lowering effect provided by the addition of a PS diuretic is unclear. Due to a large number of drugs in the T diuretics class, and the possible difference between them, there is a need to identify the best available evidence for health decision-making. This systematic review with network meta-analysis aims to compare the antihypertensive efficacy of T diuretics alone or in combination with a PS diuretic in patients with primary hypertension, as well as the safety of such drugs through the measurement of drug-related adverse events. METHODS: A comprehensive electronic search will be conducted in six electronic bibliographic databases (PubMed/MEDLINE, Cochrane Library, Embase, Web of Science, Scopus, Lilacs), a registration database ( ClinicalTrials.gov ), and Educational Resources Information Center (ERIC [ProQuest]), published from inception to the date of the search. The search will be updated towards the end of the review. A hand search of the reference sections of the included studies and cited studies will also be performed. In case of missing data, authors will be contacted by e-mail or academic social networking sites whenever possible. To be included in the review, studies must be double-blind randomized controlled trials evaluating T diuretics alone or in combination with PS diuretics in patients with primary hypertension. The primary outcome measure will be office BP. Ambulatory BP monitoring (ABPM), non-melanoma skin cancer, major adverse cardiovascular events, laboratory parameters, and the number of withdrawals will be included as secondary outcomes. The results will be quantitatively summarized using differences between the mean change from baseline or differences between means for quantitative outcomes and relative risk for dichotomous outcomes. Results will be presented as mean or relative risk with credible intervals through a league table. The treatments will also be ranked using the surface under the cumulative ranking curve method. The risk of bias will be assessed through the RoB 1.0 tool. DISCUSSION: To the best of our knowledge, this review will be the first to synthesize currently available evidence on the antihypertensive efficacy of different T diuretics alone or in combination with PS diuretics in adults with hypertension. The goals of hypertension treatment are to control high BP and to reduce associated cardiovascular morbidity and mortality, using the most appropriate therapy. Thiazides are widely used for pharmacological treatment due to their demonstrated effectiveness in reducing BP, favorable safety profile, and low cost. The results of this study will provide evidence regarding the best therapeutic strategies with T and PS diuretics, evidencing interventions with better antihypertensive efficacy and safety profile. TRIAL REGISTRATION: This systematic review and network meta-analysis was prospectively registered at the PROSPERO database ( CRD42018118492 ).

Systematic reviews on the success of dental implants present low spin of information but may be better reported and interpreted: An overview of systematic reviews with meta-analysis.

OBJECTIVE: To estimate the prevalence of spin and completeness of reporting of systematic reviews with metanalysis (SRMAs) in implant dentistry. STUDY DESIGN AND SETTING: Inclusion criteria were SRMAs of randomized clinical trials of implant dentistry on survival, success, or failure rates in humans, with no language restriction. Three databases were searched from inception to May 2021. Main outcomes were prevalence of spin (primary outcome) and completeness of reporting (secondary outcome) in abstracts and full texts. RESULTS: We identified 2481 SRMAs and 45 unique manuscripts were included. There was a low presence of spin in the abstracts and full text, except for adverse events, in which 51.1% (in the abstract) failed to mention any adverse event for summarized interventions. There was an adequate report of SRMAs in the full text except for prospective register (33.3% not reported). However, there was an incomplete report for most items in the abstract considering PRISMA-A checklist. CONCLUSION: In general, the included SRMAs presented a (a) low prevalence of spin (except for adverse events in the abstract); (b) adequate completeness of reporting in the full text (except for prospective register); and (c) incomplete report for most items in the abstracts.

Percepção dos usuários sobre a atenção primária em saúde: estudo transversal em um município de grande porte / Users' perception about primary health care: a cross-sectional study in a large municipality

O objetivo deste estudo foi avaliar o nível de satisfação dos usuários da Atenção Primária em Saúde de um município de grande porte. Trata-se de um estudo transversal, do tipo censitário e com amostra por conveniência, visto que foram incluídas todas as unidades de saúde e entrevistados os usuários que estavam na sala de espera no dia da coleta e aceitaram participar da pesquisa. Toda a coleta de dados foi realizada por meio de questionários, e,posteriormente,tabulada e analisada no software Stata 14.0. Os usuários relataram satisfação com a unidade e equipe, e com serviços assistenciais. Entretanto, usuários que manifestaram que trocariam de unidade caso isto fosse possível, tinham razões atribuídas à organização do cuidado e agendamento de consultas. Concluímos que a satisfação com os cuidados exercidos pelos profissionais e com o acolhimento de informações de cunho afetivo foram evidentemente altas, ao passo que a insatisfação com a organização do cuidado é aparente.

This study aimed to assess the level of satisfaction of users of PrimaryHealth Care in a large city. This is a cross-sectional, census-type study with a convenience sample, as all health units were included and users who were in the waiting room on the day of collection and who agreed to participate in the survey were interviewed. All data collection was performed through questionnaires, and later tabulated and analyzed using the Stata 14.0 software. Users reported satisfaction with the unit and team, and with care services. However, users who stated that they would change units if this was possible had reasons attributed to the organization of care and appointment scheduling. We conclude that satisfaction with the care provided by professionals and with the reception of information of an affective nature were evidently high, while dissatisfaction with the organization of care is apparent.

The impact of gender on researchers' assessment: A randomized controlled trial.

OBJECTIVES: This randomized controlled trial aimed to test whether women or men would be preferred with identical curriculum vitae (CV); and the impact of the career stage in the evaluators' choice. STUDY DESIGN AND SETTING: A simulated post-doctoral process was carried forward to be assessed for judgment. Level 1 and 2 Brazilian fellow researchers in the field of Dentistry were invited to act as external reviewers in a post-doctoral process and were randomly assigned to receive a CV from a woman or a man. They were required to rate the CV from 0 to 10 in scientific contribution, leadership potential, ability to work in groups, and international experience. RESULTS: For all categories of CVs evaluated, CVs from men received higher scores compared to the CVs from women. Robust variance Poisson regressions demonstrated that men were more likely to receive higher scores in all categories, despite applicants' career stage. For example, CVs from men were nearly three quarters more likely to be seen as having leadership potential than equivalent CVs from women. CONCLUSION: Gender bias is powerfully prevalent in academia in the dentistry field, despite researchers' career stage. Actions like implicit bias training must be urgently implemented to avoid (or at least decrease) that more women are harmed.

Hemostasis after percutaneous transfemoral access: A protocol for systematic review.

BACKGROUND: Access site hemostasis after percutaneous procedures done in the catheterization laboratory still needs to be better studied in relation to such aspects as the different results achieved with different hemostasis strategies, the impact of different introducer sheath sizes, and arterial versus venous access. The objective of this review is to synthesize the available scientific evidence regarding different techniques for hemostasis of femoral access sites after percutaneous diagnostic and therapeutic procedures. METHODS: This review is being reported in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). The primary outcomes will include the following vascular complications: hematoma, pseudoaneurysm, bleeding, minor, and major vascular complications. The secondary outcomes will include the following: time to hemostasis, repetition of manual compression, and device failure. A structured strategy will be used to search the PubMed/ MEDLINE, Embase, CINAHL, and CENTRAL databases. In addition, a handsearch of the reference lists of selected studies will be conducted. The ERIC research database will be queried for the gray literature and ClinicalTrials.gov, for potential results not yet published in indexed journals. Two reviewers will independently screen citations and abstracts, identify full-text articles for inclusion, extract data, and appraise the quality and risk of bias of included studies. If possible, a meta-analysis will be carried out. All estimations will be made using Review Manager 5.3. Statistical heterogeneity will be assessed by considering the I2 proxy, accompanied with qualitative indicators such as differences in procedures, interventions, and outcomes among the studies. If synthesis proves inappropriate, a narrative review will be undertaken. RESULTS: This protocol adheres to the PRISMA-P guideline to ensure clarity and completeness of reporting at all phases of the systematic review. CONCLUSION: This study will provide synthesized information on different methods used to achieve hemostasis after femoral access. ETHICS AND DISSEMINATION: Ethical approval number CAAE 19713219700005327. The results of the systematic review will be disseminated via publication in a peer-reviewed journal and through conference presentations. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019140794.

Effects of a power strength training using elastic resistance exercises on the motor and non-motor symptoms in patients with Parkinson's disease H&Y 1-3: study protocol for a randomised controlled trial (PARK-BAND Study).

INTRODUCTION: Parkinson's disease (PD) is the second most common neurodegenerative disorder in Brazil. Physical activity is a complementary intervention in managing inherent declines associated with the disease like strength, balance, gait, and functionality and benefit health-related outcomes. Here, we report the PARK-BAND Study protocol, which aims to investigate potential benefits of power training using elastic devices in participants with PD. Our intervention will be provided in patients with PD using elastic devices like elastic bands and tubes. Therefore, we used the term Park from Parkinson's disease and band from elastic bands. METHODS AND ANALYSIS: This randomised single-blind single-centre two-arm parallel, superiority trial will include 50 participants with PD attending the clinical setting. Those who meet the eligibility criteria and provide consent to participate will be randomised in a 1:1 ratio to either the exercise group, which will receive power training programme or the health education group, which will receive the education programme. Randomisation will be performed by permuted block randomisation with a block size of eight. Both groups will receive a 12-week intervention. The exercise group will have two sessions per week and the health education group will have one session per week. Changes from baseline in bradykinesia, as assessed by the Unified Parkinson's Disease Rating Scale motor examination subscore and physical functional performance, will be the primary outcomes. Secondary outcomes include other neurological, neurophysiological and physical variables, as well as the quality of life, depression, cognition, sleep quality and disturbances, assessed before and after interventions. We hypothesise that the exercise group will have greater improvement in primary and secondary outcomes than the health education group. ETHICS AND DISSEMINATION: The study is approved by the Research Ethics Committee of Hospital Universitário Walter Cantidio and all participants will provide their written informed consent (register number 91075318.1.0000.5045).Trial results will be disseminated via peer reviewed journal articles and conference presentations, reports for organisations involved with PD and for participants.

Checklists to detect potential predatory biomedical journals: a systematic review.

BACKGROUND: The increase in the number of predatory journals puts scholarly communication at risk. In order to guard against publication in predatory journals, authors may use checklists to help detect predatory journals. We believe there are a large number of such checklists yet it is uncertain whether these checklists contain similar content. We conducted a systematic review to identify checklists that help to detect potential predatory journals and examined and compared their content and measurement properties. METHODS: We searched MEDLINE, Embase, PsycINFO, ERIC, Web of Science and Library, and Information Science & Technology Abstracts (January 2012 to November 2018); university library websites (January 2019); and YouTube (January 2019). We identified sources with original checklists used to detect potential predatory journals published in English, French or Portuguese. Checklists were defined as having instructions in point form, bullet form, tabular format or listed items. We excluded checklists or guidance on recognizing "legitimate" or "trustworthy" journals. To assess risk of bias, we adapted five questions from A Checklist for Checklists tool a priori as no formal assessment tool exists for the type of review conducted. RESULTS: Of 1528 records screened, 93 met our inclusion criteria. The majority of included checklists to identify predatory journals were in English (n = 90, 97%), could be completed in fewer than five minutes (n = 68, 73%), included a mean of 11 items (range = 3 to 64) which were not weighted (n = 91, 98%), did not include qualitative guidance (n = 78, 84%), or quantitative guidance (n = 91, 98%), were not evidence-based (n = 90, 97%) and covered a mean of four of six thematic categories. Only three met our criteria for being evidence-based, i.e. scored three or more "yes" answers (low risk of bias) on the risk of bias tool. CONCLUSION: There is a plethora of published checklists that may overwhelm authors looking to efficiently guard against publishing in predatory journals. The continued development of such checklists may be confusing and of limited benefit. The similarity in checklists could lead to the creation of one evidence-based tool serving authors from all disciplines.

Intradialytic training in patients with end-stage renal disease: a systematic review and meta-analysis of randomized clinical trials assessing the effects of five different training interventions.

OBJECTIVE: Patients with end-stage renal disease (ESRD) undergoing hemodialysis may have reduced dialysis adequacy (Kt/V), low cardiorespiratory fitness, and worse prognosis. Different types of intradialytic training (IDT) may serve as an adjunct therapy for the management of the ESRD. This systematic review and meta-analysis aimed to assess the impact of different types of IDT on clinical outcomes and functional parameters in ESRD. METHODS: PubMed, Embase, CINAHL, Cochrane CENTRAL, Scopus, SPORTDiscus, and Google Scholar were searched for randomized clinical trials in adult patients with ESRD which compared IDT with usual care (UC), without language restrictions and published up to July 2019; a handsearch of references was also performed. Certainty of evidence was assessed using GRADE, and risk of bias in primary studies with the RoB 1.0 tool. RESULTS: Fifty studies were included (n = 1757). Compared to UC, aerobic IDT improved Kt/V (WMD = 0.08), VO2peak (WMD = 2.07 mL/kg/min), 6-minute walk test (6MWT) distance (64.98 m), reduced systolic blood pressure (- 10.07 mmHg) and C-reactive protein (- 3.28 mg/L). Resistance training increased 6MWT distance (68.50 m). Combined training increased VO2peak (5.41 mL/kg/min) and reduced diastolic blood pressure (- 5.76 mmHg). Functional electrostimulation (FES) and inspiratory muscle training (IMT) improved 6MWT distance (54.14 m and 117.62 m, respectively). There was no impact on total cholesterol, interleukin-6, or hemoglobin levels. There was no difference in incidence of adverse events between the IDT and control groups. The certainty of evidence was variable according to the GRADE scale, with most outcomes rated very low certainty. The risk of bias assessment of primary studies showed unclear risk in most. CONCLUSIONS: Aerobic, resistance, and combined training during hemodialysis, as well as FES and IMT, demonstrated to be effective for the treatment of the patient with ESRD. Our data should be interpreted in light of the unclear risk of bias of most evaluated articles and the low to very low certainty of evidence for evaluated outcomes.

Efficacy of chlorthalidone and hydrochlorothiazide in combination with amiloride in multiple doses on blood pressure in patients with primary hypertension: a protocol for a factorial randomized controlled trial.

BACKGROUND: Thiazide diuretics have demonstrated favorable blood pressure lowering efficacy, but the equivalent doses of their more common agents, chlorthalidone and hydrochlorothiazide, are still unclear. Further, concerns exist regarding adverse metabolic effects, which may be attenuated with the concomitant administration of a potassium-sparing diuretic, such as amiloride. This trial aims to investigate the efficacy of chlorthalidone and hydrochlorothiazide, in combination with amiloride at different doses, for initial management of patients with primary hypertension. METHODS/DESIGN: This is a factorial (2 × 2) randomized double-blinded clinical trial comparing the association of a thiazide diuretic (chlorthalidone 25 mg/day or hydrochlorothiazide 50 mg/day) with a potassium-sparing diuretic (amiloride 10 mg/day or amiloride 20 mg/day) in patients with primary hypertension. The primary outcome will be the mean change from baseline in 24-h systolic and diastolic blood pressure measured by ambulatory blood pressure monitoring. The secondary outcomes will be the mean change from baseline in daytime and nighttime systolic and diastolic blood pressure measured by ambulatory blood pressure monitoring, mean change from baseline in systolic and diastolic blood pressure measured by office blood pressure, incidence of adverse events, variation of laboratory parameters, and proportion of patients who achieved blood pressure control. The follow-up will last 12 weeks. For a P alpha of 0.05, power of 80%, standard deviation of 9 mmHg, and absolute difference of 6 mmHg on systolic blood pressure on 24-h ambulatory blood pressure monitoring, it will be necessary to study a total of 76 patients. The sample size will be increased by 10% to compensate for losses, resulting in 84 patients being randomized. DISCUSSION: Diuretics are pivotal drugs for the treatment of hypertension. Chlorthalidone and hydrochlorothiazide, in combination with amiloride in multiple doses, will be tested in terms of blood pressure lowering efficacy and safety. Since the intensity of blood pressure reduction is the major determinant of reduction in cardiovascular risk in hypertensive patients, this study will help to determine which combination of diuretics represents the most appropriate treatment for this population.
