Abstract
This systematic review aimed to summarize randomized clinical trials that compared the postprandial glycemic and insulinemic metabolic response after eating isocaloric and standardized carbohydrate meals consumed at two moments: morning versus night, in healthy individuals who were not shift workers. The search strategy consisted of an electronic search using the following electronic databases: MEDLINE (via PubMed), EMBASE (via Elsevier), LILACs (Virtual Health Library - VHL), Cochrane Registers of Clinical Trials (CENTRAL, via Wiley) and gray literature (Opengray.eu). The PICO strategy was used to define the search terms (P: healthy adults, I: nocturnal intake, C: morning intake, O: area under the curve (AUC) of the postprandial glucose and insulin response). This review was reported according to the PRISMA statement. From the 3757 articles found, 412 were duplicates and excluded, totaling 3345 that had their titles and abstracts read. A total of 42 articles met the inclusion criteria and were read in full, and eight studies were included in the systematic review. The certainty of the evidence was assessed using GRADE. The results showed, with moderate quality of evidence, a postprandial response with higher glycemic values in the evening compared to the morning (SMD = 1.30; 95% CI, 1.01 to 1.59; I2 = 0%; p < 0.00001; 8 studies and 116 participants). No differences were found between insulin values at night and in the morning (SMD = 0.19; 95% CI, -0.10 to 0.49; 6 studies and 90 participants). We concluded that the intake of carbohydrates at night leads to higher glycemic, but not insulinemic, postprandial values. Revision Record: PROSPERO number CRD42019137862 available at: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42019137862 Key teaching points and nutritional relevanceThis systematic review summarized randomized clinical trials that compared the postprandial glycemic and insulinemic response after eating carbohydrate meals in the morning versus at night.A total of eight studies were included in the systematic review; the results showed a postprandial response with higher glycemic values in the evening compared to the morning.No differences were found between insulin values at night and in the morning;• The intake of carbohydrates at night leads to higher glycemic, but not insulinemic, postprandial values.

Abstract
INTRODUCTION Spinal infusions of either fentanyl or sufentanil have been reported in international reports, articles, and scientific events worldwide. This study aimed to determine whether intrathecal fentanyl or sufentanil offers safety in mortality and perioperative adverse events. METHODS MEDLINE (via PubMed), EMBASE, CENTRAL (Cochrane library databases), gray literature, hand-searching, and clinicaltrials.gov were systematically searched. Randomized controlled trials with no language, data, or status restrictions were included, comparing the effectiveness and safety of adding spinal lipophilic opioid to local anesthetics (LAs). Data were pooled using the random-effects models or fixed-effect models based on heterogeneity. RESULTS The initial search retrieved 4469 records; 3241 records were eligible, and 3152 articles were excluded after reading titles and abstracts, with a high agreement rate (98.6%). After reading the full texts, 76 articles remained. Spinal fentanyl and sufentanil significantly reduced postoperative pain and opioid consumption, increased analgesia and pruritus. Fentanyl, but not sufentanil, significantly reduced both postoperative nausea and vomiting, and postoperative shivering; compared to LAs alone. The analyzed studies did not report any case of in-hospital mortality related to spinal lipophilic opioids. The rate of respiratory depression was 0.7% and 0.8% when spinal fentanyl or sufentanil was added and when it was not, respectively. Episodes of respiratory depression were rare, uneventful, occurred intraoperatively, and were easily manageable. CONCLUSION There is moderate to high quality certainty that there is evidence regarding the safety and effectiveness of adding lipophilic opioids to LAs in spinal anesthesia.

Abstract
BACKGROUND Varicose veins are enlarged and tortuous veins, affecting up to one-third of the world's population. They can be a cause of chronic venous insufficiency, which is characterised by oedema, pigmentation, eczema, lipodermatosclerosis, atrophie blanche, and healed or active venous ulcers. Injection sclerotherapy (liquid or foam) is widely used for treatment of varicose veins aiming to transform the varicose veins into a fibrous cord. However, there is limited evidence regarding its effectiveness and safety, especially in patients with more severe disease. This is the second update of the review first published in 2002. OBJECTIVES To assess the effectiveness and safety of injection sclerotherapy for the treatment of varicose veins. SEARCH METHODS For this update, the Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, AMED, CINAHL, and LILACS databases, and the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registries, on 20 July 2021. SELECTION CRITERIA We included all randomised controlled trials (RCTs) (including cluster-randomised trials and first phase cross-over studies) that used injection sclerotherapy for the treatment of varicose veins. DATA COLLECTION AND ANALYSIS Two review authors independently assessed, selected and extracted data. Disagreements were cross-checked by a third review author. We used Cochrane's Risk of bias tool to assess the risk of bias. The outcomes of interest were cosmetic appearance, complications, residual varicose veins, quality of life (QoL), persistence of symptoms, and recurrent varicose veins. We calculated risk ratios (RRs) or mean difference (MD) with 95% confidence intervals (CIs). We used the worst-case-scenario for dichotomous data imputation for intention-to-treat analyses. For continuous outcomes, we used the 'last-observation-carried-forward' for data imputation if there was balanced loss to follow-up. We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS We included 23 new RCTs for this update, bringing the total to 28 studies involving 4278 participants. The studies differed in their design, and in which sclerotherapy method, agent or concentration was used. None of the included RCTs compared sclerotherapy to no intervention or to any pharmacological therapy. The certainty of the evidence was downgraded for risk of bias, low number of studies providing information for each outcome, low number of participants, clinical differences between the study participants, and wide CIs. Sclerotherapy versus placebo Foam sclerotherapy may improve cosmetic appearance as measured by IPR-V (independent photography review - visible varicose veins scores) compared to placebo (polidocanol 1%: mean difference (MD) -0.76, 95% CI -0.91 to -0.60; 2 studies, 223 participants; very low-certainty evidence); however, deep vein thrombosis (DVT) rates may be slightly increased in this intervention group (RR 5.10, 95% CI 1.30 to 20.01; 3 studies, 302 participants; very low-certainty evidence). Residual varicose vein rates may be decreased following polidocanol 1% compared to placebo (RR 0.19, 95% CI 0.13 to 0.29; 2 studies, 225 participants; very low-certainty evidence). Following polidocanol 1% use, there may be a possible improvement in QoL as assessed using the VEINES-QOL/Sym questionnaire (MD 12.41, 95% CI 9.56 to 15.26; 3 studies, 299 participants; very low-certainty evidence), and possible improvement in varicose vein symptoms as assessed using the Venous Clinical Severity Score (VCSS) (MD -3.25, 95% CI -3.90 to -2.60; 2 studies, 223 participants; low-certainty evidence). Recurrent varicose veins were not reported for this comparison. Foam sclerotherapy versus foam sclerotherapy with different concentrations Three individual RCTs reported no evidence of a difference in cosmetic appearance after comparing different concentrations of the intervention; data could not be pooled for two of the three studies (RR 1.11, 95% CI 0.84 to 1.47; 1 study, 80 participants; very low-certainty evidence). Similarly, there was no clear difference in rates of thromboembolic complications when comparing one foam concentration with another (RR 1.47, 95% CI 0.41 to 5.33; 3 studies, 371 participants; very low-certainty evidence). Three RCTs investigating higher concentrations of polidocanol foam indicated the rate of residual varicose veins may be slightly decreased in the polidocanol 3% foam group compared to 1% (RR 0.67, 95% CI 0.43 to 1.04; 3 studies, 371 participants; moderate-certainty evidence). No clear improvement in QoL was detected. Two RCTs reported improved VCSS scores with increasing concentrations of foam. Persistence of symptoms were not reported for this comparison. There was no clear difference in recurrent varicose vein rates (RR 0.91, 95% CI 0.62 to 1.32; 1 study, 148 participants; low-certainty evidence). Foam sclerotherapy versus liquid sclerotherapy One RCT reported on cosmetic appearance with no evidence of a difference between foam or liquid sclerotherapy (patient satisfaction scale MD 0.2, 95% CI -0.27 to 0.67; 1 study, 126 participants; very low-certainty evidence). None of the RCTs investigated thromboembolic complications, QoL or persistence of symptoms. Six studies individually showed there may be a benefit to polidocanol 3% foam over liquid sclerotherapy in reducing residual varicose vein rate; pooling data from two studies showed a RR of 0.51, with 95% CI 0.41 to 0.65; 203 participants; very low-certainty evidence. One study reported no clear difference in recurrent varicose vein rates when comparing sodium tetradecyl sulphate (STS) foam or liquid (RR 1.10, 95% CI 0.86 to 1.42; 1 study, 286 participants; very low-certainty evidence). Sclerotherapy versus sclerotherapy with different substances Four RCTs compared sclerotherapy versus sclerotherapy with any other substance. We were unable to combine the data due to heterogeneity or assess the certainty of the evidence due to insufficient data. AUTHORS' CONCLUSIONS There is a very low to low-certainty evidence that, compared to placebo, sclerotherapy is an effective and safe treatment for varicose veins concerning cosmetic appearance, residual varicose veins, QoL, and persistence of symptoms. Rates of DVT may be slightly increased and there were no data concerning recurrent varicose veins. There was limited or no evidence for one concentration of foam compared to another; foam compared to liquid sclerotherapy; foam compared to any other substance; or one technique compared to another. There is a need for high-quality trials using standardised sclerosant doses, with clearly defined core outcome sets, and measurement time points to increase the certainty of the evidence.

Abstract
CONTEXT A possible association between self-reported short sleep duration and risk of obesity has been studied. OBJECTIVE To analyze the association between sleep duration and obesity. METHODS The LILACS, Medline, Central, Embase, and OpenGrey databases were searched from inception until July 2020. Two authors screened the studies independently according to the PECO strategy, as follows: participants: > 18 years old; exposure: short sleep duration; control: regular sleep; outcome: obesity). Only cohort studies were included. A total of 3286 studies were retrieved with the search strategy, but only 36 were included. Disagreements were resolved by a third author. The quality of studies was assessed with Newcastle-Ottawa Quality Assessment Form for Cohort Studies. The certainty of the evidence was assessed using Grading of Recommendations Assessment, Development, and Evaluation. RESULTS Thirty-six studies were included, and 22 contributed quantitative data. Most of the studies (n = 27) assessed sleep by self-report. The meta-analysis showed a significant association between self-reported short sleep and development of obesity, and the chances of developing obesity increased when self-reported sleep duration decreased. CONCLUSIONS Self-reported short sleep was significantly associated with a higher incidence of obesity, with moderate quality of evidence. SYSTEMATIC REVIEW REGISTRATION PROSPERO registration no.

Abstract
A review of systematic reviews (SRs) and a critical appraisal study was conducted at Escola Paulista de Medicina, Universidade Federal de São Paulo (Unifesp). The objectives of this review are (1) to identify all published SRs comparing the effectiveness and safety of carotid endarterectomy (CEA) versus carotid artery stenting (CAS) for carotid artery stenosis, (2) to assess their methodological quality and (3) to compare the primary studies contained in each SR. We included 17 SRs published between 2005 and 2017. None of the SRs fulfilled all items of AMSTAR-2. The overall confidence in the results was graded as critically low for 16 SRs (94%) and low for 1 SR (6%). Five items were judged inadequate in all SRs: reference to a published protocol, explanation to the selection of study design, comprehensive search of the literature, methods for statistical combination of findings and consideration of the risk of bias on the results of meta-analysis. In total, 15 randomised clinical trials (RCTs) were included at least in one SR. The number of included RCTs in each SR was inconsistent (4 to 15) and was not related to the year of publication of the SR. Our study found redundant and low methodological quality SR comparing CAS versus CEA for carotid stenosis.

Abstract
INTRODUCTION AND OBJECTIVES The incidence of Postoperative Nausea and Vomiting (PONV) after video cholecystectomy is high. Progress in pharmacological PONV prophylaxis includes a new generation of 5-HT3 antagonists. This study aims to assess the effect of the 5-HT3 antagonist in postanesthetic antiemetic management of patients submitted to laparoscopic cholecystectomy with total intravenous anesthesia. METHODS Sixty individuals who underwent video cholecystectomy were randomized into three groups of 20 individuals according to the treatment administered: 0.125 mg of palonosetron (Group 1); 4 mg of ondansetron associated with 4 mg of dexamethasone (Group 2); 4 mg of dexamethasone (Group 3). General intravenous anesthesia was performed with propofol, remifentanil and rocuronium. The group to which the participant belonged was concealed from the investigator who assessed drug effect. PONV was assessed using the Rhodes Scale at 12 and 24 hours after surgery. Rescue medication was 0.655 to 1.5 mg of droperidol. RESULTS Group 1 presented a lower incidence of PONV and required less rescue medication in the first postoperative hour. There was no significant difference among the three groups regarding PONV incidence in the first 12 postoperative hours. Groups 1 and 2 were superior to Group 3 regarding the control of PONV from 12 to 24 hours, and after rescue medication from 12 to 24 hours. Group 1 showed significantly superior nausea control in the first 12 postoperative hours. CONCLUSIONS The present study showed evidence that palonosetron is superior to the drugs compared regarding a protracted antiemetic effect and less requirement of rescue drugs, mainly related to its ability to completely inhibit the uncomfortable symptom of nausea.

Abstract
OBJECTIVES A core outcome set (COS) is an agreed standardised minimum collection of outcomes that should be measured and reported in research in a specific area of health. Cochrane systematic reviews ('reviews') are rigorous reviews on health-related topics conducted under the auspices of Cochrane. This study examines the use of existing COS to inform the choice of outcomes in Cochrane systematic reviews ('reviews') and investigates the views of the coordinating editors of Cochrane Review Groups (CRGs) on this topic. METHODS A cohort of 100 recently published or updated Cochrane reviews were assessed for reference to a COS being used to inform the choice of outcomes for the review. Existing COS, published 2 or more years before the review publication, were then identified to assess how often a reviewer could have used a relevant COS if it was available. We asked 52 CRG coordinating editors about their involvement in COS development, how outcomes are selected for reviews in their CRG and their views of the advantages and challenges surrounding the standardisation of outcomes within their CRG. RESULTS In the cohort of reviews from 2019, 40% (40/100) of reviewers noted problems due to outcome inconsistency across the included studies. In 7% (7/100) of reviews, a COS was referenced in relation to the choice of outcomes for the review. Relevant existing COS could be considered for a review update in 35% of the others (33/93). Most editors who responded (31/36, 86%) thought that COS should definitely or possibly be used to inform the choice of outcomes in a review. CONCLUSIONS Systematic reviewers are continuing to note outcome heterogeneity but are starting to use COS to inform their reviews. There is potential for greater uptake of COS in Cochrane reviews.

Abstract
We conducted a systematic review to compare the effectiveness and safety of exercise
versus no exercise for patients with asymptomatic aortic aneurysm. We followed the
guidelines set out in the Cochrane systematic review handbook. We searched Medline,
Embase, CENTRAL, LILACS, PeDRO, CINAHL, clinicaltrials.gov, ICTRP, and OpenGrey using
the MeSH terms “aortic aneurysm” and “exercise”. 1189 references were identified.
Five clinical trials were included. No exercise-related deaths or aortic ruptures
occurred in these trials. Exercise did not reduce the aneurysm expansion rate at 12
weeks to 12 months (mean difference [MD], −0.05; 95% confidence interval [CI], −0.13
to 0.03). Six weeks of preoperative exercise reduced severe renal and cardiac
complications (risk ratio, 0.54; 95% CI, 0.31–0.93) and the length of intensive care
unit stay (MD, −1.00; 95% CI, −1.26 to −0.74). Preoperative and postoperative forward
walking reduced the length of hospital stay (MD, −0.69; 95% CI, −1.24 to −0.14). The
evidence was graded as ‘very low’ level.

Abstract
BACKGROUND Varicose veins affect nearly 30% of the world's population. This condition is a social problem and needs interventions to improve quality of life and reduce risks. Recently, new and less invasive methods for varicose vein treatment have emerged. There is a need to define the best treatment options and to reduce the risks and costs. Since there are cosmetic implications, treatments for which effectiveness remains unproven present risks to consumers and higher costs for stakeholders. These risks and costs justify conducting an overview of systematic reviews to summarize the evidence. DESIGN AND SETTING Overview of systematic reviews within the Discipline of Evidence-Based Health, at Universidade Federal de São Paulo (UNIFESP). METHODS Systematic reviews on clinical or surgical treatments for varicose veins were included, with no restrictions on language or publication date. RESULTS 51 reviews fulfilled the inclusion criteria. Outcomes and comparators were described, and a narrative review was conducted. Overall, there was no evidence that compression stockings should be recommended for patients as the initial treatment or after surgical interventions. There was low to moderate evidence that minimally invasive therapies (endovenous laser therapy, radiofrequency ablation or foam sclerotherapy) are as safe and effective as conventional surgery (ligation and stripping). Among these systematic reviews, only 18 were judged to present high quality. CONCLUSIONS There was evidence of low to moderate quality that minimally invasive treatments, including foam sclerotherapy, laser and radiofrequency therapy are comparable to conventional surgery, regarding effectiveness and safety for treatment of varicose veins.

Abstract
CONTEXTO: A variabilidade hemodinâmica da pletismografia a ar é conhecida, mas o exato papel dessa variabilidade no cotidiano clínico não foi investigado, podendo ter algum significado clínico ainda não explorado. Sabe-se que há sobreposição entre as classes clínicas (C0 a C6) da classificação CEAP e mesmo entre membros inferiores de uma mesma classe clínica. OBJETIVO: Avaliar a variabilidade hemodinâmica dos parâmetros da pletismografia a ar nas classes clínicas da classificação CEAP. MÉTODO: Este estudo retrospectivo confronta a doença varicosa de membros inferiores classificada de C0 a C6 pela classificação CEAP com os parâmetros hemodinâmicos venosos obtidos pela pletismografia a ar. Os dados obtidos foram tabulados e analisados em suas classes clínicas pelos testes de variância de Kruskal-Wallys e Barllett. RESULTADOS: Foram realizados 310 exames em 230 pacientes cujas idades variaram entre 19 a 81 anos, com uma média de 46,2 anos. Os parâmetros índice de enchimento venoso e volume venoso funcional mostraram aumento da variabilidade hemodinâmica quando analisados na classe clínica C0 do CEAP, demonstrada por meio do coeficiente de variabilidade que, para o índice de enchimento venoso foi de 28,12% na classe clínica C0 e se manteve acima de 57% nas classes de C2 a C6. A fração de ejeção e a fração de volume residual não aumentaram a variabilidade quando comparados com a classe clínica C0 do CEAP. CONCLUSÃO: O índice de enchimento venoso foi o melhor parâmetro para avaliação e triagem de pacientes com insuficiência venosa crônica, mas tem grande variabilidade nas classes clínicas C2 a C6 do CEAP.
