RESUMO

AIM: To conduct a systematic review and meta-analysis to understand the timing and factors associated with anti-programmed cell death protein-1 (PD-1)/anti-programmed cell death protein-1 ligand (PD-L1) inhibitor-induced Type 1 diabetes. METHODS: We searched MEDLINE, EMBASE, SCOPUS and Cochrane databases (August 2000-2018) for studies of any design on immune checkpoint inhibitors. A total of 71 cases were reviewed from 56 publications. Comparisons were made using Fisher's exact and Student's t-tests. RESULTS: The mean ± sd age at Type 1 diabetes presentation was 61.7±12.2 years, 55% of cases were in men, and melanoma (53.5%) was the most frequent cancer. The median time to Type 1 diabetes onset was 49 (5-448) days with ketoacidosis in 76% of cases. The average ± sd HbA1c concentration was 62 ± 0.3 mmol/mol (7.84±1.0%) at presentation. All cases had insulin deficiency and required permanent exogenous insulin treatment. Half of the cases had Type 1 diabetes-associated antibodies at presentation, and those with antibodies had a more rapid onset (P=0.005) and higher incidence of diabetic ketoacidosis (P=0.02) compared to people without antibodies. CONCLUSIONS: Many people developed Type 1 diabetes within 3 months of initial PD-1/PD-L1 inhibitor exposure. People presenting with Type 1 diabetes-associated antibodies had a more rapid onset and higher incidence of ketoacidosis than those without antibodies. Healthcare providers caring for people receiving these state-of-the-art therapies need to be aware of this potential severe adverse event.

RESUMO

OBJECTIVES: The aim of the study was to develop a Grading of Recommendations, Assessment, Development and Evaluation (GRADE) summary of findings (SoF) table format that displays the critical information from a network meta-analysis (NMA). STUDY DESIGN AND SETTING: We applied a user experience model for data analysis based on four rounds of semistructured interviews. RESULTS: We interviewed 32 stakeholders who conduct or use MA. Four rounds of interviews produced six candidate NMA-SoF tables. Users found a final NMA-SoF table that included the following components highly acceptable: (1) details of the clinical question (PICO), (2) a plot depicting network geometry, (3) relative and absolute effect estimates, (4) certainty of evidence, (5) ranking of treatments, and (6) interpretation of findings. CONCLUSION: Using stakeholder feedback, we developed a new GRADE NMA-SoF table that includes the relevant components that facilitate understanding NMA findings and health decision-making.

RESUMO

This article describes conceptual advances of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) working group guidance to evaluate the certainty of evidence (confidence in evidence, quality of evidence) from network meta-analysis (NMA). Application of the original GRADE guidance, published in 2014, in a number of NMAs has resulted in advances that strengthen its conceptual basis and make the process more efficient. This guidance will be useful for systematic review authors who aim to assess the certainty of all pairwise comparisons from an NMA and who are familiar with the basic concepts of NMA and the traditional GRADE approach for pairwise meta-analysis. Two principles of the original GRADE NMA guidance are that we need to rate the certainty of the evidence for each pairwise comparison within a network separately and that in doing so we need to consider both the direct and indirect evidence. We present, discuss, and illustrate four conceptual advances: (1) consideration of imprecision is not necessary when rating the direct and indirect estimates to inform the rating of NMA estimates, (2) there is no need to rate the indirect evidence when the certainty of the direct evidence is high and the contribution of the direct evidence to the network estimate is at least as great as that of the indirect evidence, (3) we should not trust a statistical test of global incoherence of the network to assess incoherence at the pairwise comparison level, and (4) in the presence of incoherence between direct and indirect evidence, the certainty of the evidence of each estimate can help decide which estimate to believe.

RESUMO

STUDY OBJECTIVE: We conduct a systematic review and meta-analysis to evaluate the effectiveness of apneic oxygenation during emergency intubation. METHODS: We searched Ovid MEDLINE, Ovid EMBASE, Ovid CENTRAL, and Scopus databases for randomized controlled trials and observational studies from 2006 until July 2016, without language restrictions. Gray literature, clinicaltrials.gov, and reference lists of articles were hand searched. We conducted a meta-analysis with random-effects models to evaluate first-pass success rates, incidence of hypoxemia, and lowest peri-intubation SpO2 between apneic oxygenation and standard oxygenation cases. RESULTS: A total of 1,386 studies were screened and 77 selected for full-text review. A total of 14 studies were included for qualitative analysis, and 8 studies (1,837 patients) underwent quantitative analysis. In the meta-analysis of 8 studies (1,837 patients), apneic oxygenation was associated with decreased hypoxemia (odds ratio [OR] 0.66; 95% confidence interval [CI] 0.52 to 0.84), but was not associated with decreased severe hypoxemia (6 studies; 1,043 patients; OR 0.86; 95% CI 0.47 to 1.57) or life-threatening hypoxemia (5 studies; 1,003 patients; OR 0.90; 95% CI 0.52 to 1.55). Apneic oxygenation was associated with increased first-pass success rate (6 studies; 1,658 patients; OR 1.59; 95% CI 1.04 to 2.44) and increased lowest peri-intubation SpO2 (6 studies; 1,043 patients; weighted mean difference 2.2%; 95% CI 0.8% to 3.6%). CONCLUSION: In this meta-analysis, apneic oxygenation was associated with increased peri-intubation oxygen saturation, decreased rates of hypoxemia, and increased first-pass intubation success.

RESUMO

BACKGROUND AND PURPOSE: Outcomes of endovascular treatment of very small intracranial aneurysms are still not well-characterized. Recently, several series assessing coil embolization of tiny aneurysms have presented new promising results. Thus, we performed a systematic review and meta-analysis of studies evaluating endovascular treatment of very small intracranial aneurysms. MATERIALS AND METHODS: We conducted a computerized search of Scopus, Medline, and the Web of Science for studies on endovascular treatment of very small (≤3 mm in diameter) intracranial aneurysms published between January 1996 and May 2015. Using a random-effects model, we evaluated clinical and angiographic outcomes. RESULTS: Twenty-two studies with 1105 tiny aneurysms (844 ruptured and 261 unruptured) endovascularly treated were included. Postoperative and long-term complete occlusion was achieved in 85% (95% CI, 78%-90%) and 91% (95% CI, 87%-94%) of aneurysms, respectively. The recanalization rate was 6% (95% CI, 4%-11%) and retreatment occurred in 7% (95% CI, 5%-9%) of cases. Seventy-nine percent (95% CI, 64%-89%) of patients had good neurologic outcome at long-term follow-up. Intraprocedural rupture occurred in 7% (95% CI, 5%-9%) of the coiling procedures, while thromboembolic complications occurred in 4% (95% CI, 3%-6%). CONCLUSIONS: Coil embolization of very small intracranial aneurysms can be performed safely and effectively. In the case of unruptured aneurysms, procedure-related complications are not negligible. Patients and providers should consider such risks when engaged in a shared decision-making process.

RESUMO

Tyrosine kinase inhibitors (TKI) are the initial treatment for majority of newly diagnosed patients with chronic myelogenous leukemia (CML) in chronic phase (CP) and are associated with marked improvement in hematological, cytogenetic, molecular response and survival rates compared with other therapies. In this review, we summarize the evidence of TKI efficacy for patients with newly diagnosed CP-CML. Six trials at low risk of bias evaluating TKIs as an initial treatment in adults with newly diagnosed CP-CML and enrolling 2,456 patients were included. Follow-up times ranged from a median of 3 months to 5 years. Direct comparison showed statistically higher rates of major molecular response (MMR ≤ 0.1%(IS)) achievement with second-generation TKIs at 12 months which was sustained throughout treatment period. Bayesian mixed-treatment comparison (MTC) analysis demonstrated superiority of both nilotinib and dasatinib over imatinib in terms of efficacy. Nilotinib was associated with higher deeper molecular responses (MR(4.5) ≤ 0.0032%(IS)) at 60 months than dasatinib but no difference in MMR. The differences between nilotinib and dasatinib are likely clinically trivial. Among TKIs, nilotinib was found to have the best survival profile. Both nilotinib and dasatinib are associated with significantly better MMR compared to imatinib that is sustained over 60 months. This analysis shows that new-generation TKIs are not only showing faster response but also maintaining a more potent one through longer follow-up period. It is important to note out that MTC is not a substitute for well-conducted RCTs investigating direct comparisons.

RESUMO

We describe two cases of coronary angioplasty with stents implantation in bifurcational lesion of the left anterior descending artery and the diagonal branch using new techniques successfully performed. Angiographic reestenosis was not present after seven months in one case and the patient was asymptomatic after six months of clinical follow-up in the other.

RESUMO

We describe a case of coronary stenosis located in an unprotected left main coronary artery, treated primarily and electively with the placement of a coronary stent. As a function of the large mass of myocardium involved, this patient would be considered a classical candidate for direct surgery, because the inherent risk involved with conventional balloon angioplasty, mainly due to the eventual occurrence of acute closure during the procedure. Since the previsibility of the immediate results with the use of coronary stents was significantly improved, we propose this new therapeutic approach for this traditionally surgical case, that has been performed with success and without any complication. This strategy for the treatment of unprotected left main lesions with the elective placement of Palmaz-Schatz stents, has not yet been proposed or applied in our country, and may represent a new universe of indication of percutaneous treatment of coronary artery disease, no longer approaching the left main stem only in special or emergency situations, usually a result of complications of left main manipulation during angioplasty of the coronary system. The patient involved in this case did not show any contraindication for the treatment with conventional open heart surgery.
