RESUMO
In this systematic review and dose-response meta-analysis, we aimed to assess whether coffee and tea consumption is related to the risk of glioma. We performed a systematic literature search using PubMed, Embase, Scopus and the EuropePMC from the inception of database up until 1 October 2020. Exposures in the present study were coffee and tea consumption, the main outcome was the incidence of glioma. The present study compares the association between the exposure of coffee and tea with the incidence of glioma, and the results are reported in relative risks (RR). There are 12 unique studies comprising of 1 960 731 participants with 2987 glioma cases. Higher coffee consumption was associated with a statistically non-significant trend towards lower risk of glioma (RR 0·77 (95 % CI 0·55, 1·03), P= 0·11; I2:75·27 %). Meta-regression showed that the association between coffee and glioma was reduced by smoking (P= 0·029). Higher tea consumption was associated with a lower risk of glioma (RR 0·84 (95 % CI 0·71, 0·98), P= 0·030; I2:16·42 %). Sensitivity analysis by removal of case-control studies showed that higher coffee consumption (RR 0·85 (95 % CI 0·72, 1·00), P= 0·046; I2:0 %) and higher tea consumption (RR 0·81 (95 % CI 0·70, 0·93), P= 0·004; I2:0 %, Pnon-linearity = 0·140) were associated with lower risk of glioma. Dose-response meta-analysis showed that every one cup of coffee per day decreases the risk of glioma by 3 % (RR 0·97 (95 % CI 0·94, 0·99), P= 0·016, Pnon-linearity = 0·054) and every one cup of tea per day decreases the risk of glioma by 3 % (RR 0·97 (95 % CI 0·94, 1·00), P= 0·048). This meta-analysis showed apparent association between coffee and tea intake and risk of glioma.

BACKGROUND: Contrast-induced nephropathy (CIN) is associated with increased mortality and morbidity in patients undergoing coronary angiography (CAG) and percutaneous coronary intervention (PCI). We aimed to assess the latest evidence on the effect of remote ischemic preconditioning (RIPC) on the incidence of CIN in patients undergoing CAG/PCI. METHODS: We performed a comprehensive search on topics assessing RIPC and CIN in CAG/PCI patients from inception up until July 2019 through several electronic databases. RESULTS: There were a total of 1,925 subjects from 14 randomized controlled trials. Remote ischemic preconditioning was associated with reduced CIN incidence in patients undergoing CAG/PCI (OR 0.41 [0.30, 0.55], p < .001; I2 : 22%). The nephroprotective effect was also demonstrated in those at moderate-high risk for CIN subgroup (OR 0.41 [0.29, 0.58], p < .001; I2 : 26%) and PCI-only subgroup (OR 0.41 [0.29, 0.58], p < .001; I2 : 0%). Time from RIPC to CAG/PCI has similar effectiveness among ≤45, ≤60, and ≤120 min. Mortality, rehospitalization, hemodialysis, and major adverse events were lower in the RIPC group (OR 0.50 [0.33, 0.76], p = .001; I2 : 0%). Grading of recommendations assessment, development and evaluation (GRADE) assessment showed that RIPC has high evidence certainty for reducing CIN in patients undergoing PCI/CAG, moderate-high risk subgroup, and PCI-only subgroup with absolute reduction of 97 per 1,000, 129 per 1,000, and 121 per 1,000, respectively. Harbord test showed no evidence for the presence of small-study effects (p = .157). CONCLUSIONS: Remote ischemic preconditioning is an effective procedure to reduce the risk of CIN and should be considered in patients with moderate-high risk at developing CIN.

BACKGROUND: Fragmented QRS (fQRS) is postulated to be associated with ventricular dyssynchrony and might be able to predict a nonresponse to cardiac resynchronization therapy (CRT) implantation. In this systematic review and meta-analysis, we aim to assess whether fQRS can be a marker of intraventricular dyssynchronies in patients with ischemic and nonischemic cardiomyopathy and whether it is an independent predictor of nonresponse in patients receiving CRT. METHODS: We performed a comprehensive search on topics that assesses fQRS and its association with intraventricular dyssynchrony and nonresponse to CRT up until September 2019. RESULTS: Fragmented QRS is associated with intraventricular dyssynchrony (OR 10.34 [3.39, 31.54], p < .001; I2 : 80% with sensitivity 76.8%, specificity 77%, LR+ 3.3, and LR- 0.3). Subgroup analysis showed that fQRS is associated with intraventricular dyssynchrony in patients with narrow QRS complex (OR 20.92 [12.24, 35.73], p < .001; I2 : 0%) and nonischemic cardiomyopathy (OR of 19.97 [12.12, 32.92], p < .001; I2 : 0%). Fragmented QRS was also associated with a higher time-to-peak myocardial sustained systolic (Ts-SD) (OR 15.19 [12.58, 17.80], p < .001; I2 : 0% and positive Yu index (OR 15.61 [9.07, 26.86], p < .001; I2 : 0%). Fragmented QRS has a pooled adjusted OR of OR of 1.70 [1.35, 2.14], p < .001; I2 : 62% for association with a nonresponse to CRT. QRS duration is found to be higher in nonresponders group mean difference -8.54 [-13.38, -3.70], p < .001; I2 : 70%. CONCLUSION: Fragmented QRS is associated with intraventricular dyssynchrony and is independently associated with nonresponse to cardiac resynchronization therapy.

BACKGROUND: This systematic review and meta-analysis aimed to evaluate the efficacy and safety of direct vs preimplantation balloon valvuloplasty (predilatation) before transcatheter aortic valve replacement (TAVR). METHODS: We performed a systematic literature search up until March 2020 from PubMed, SCOPUS, EuropePMC, Cochrane Central Database, ProQuest, and ClinicalTrials.gov. We included randomized controlled trial (RCT) and prospective-matched cohorts that compared direct TAVR and preimplantation balloon valvuloplasty before TAVR. The primary outcome was the device success as defined by Valve Academic Research Consortium 2. The secondary outcome was a patient-prosthesis mismatch, the need for balloon postdilatation, composite adverse events, and 1-year mortality. RESULTS: There were a total of 3078⬠patients from eight studies. This meta-analysis showed that direct TAVR has a similar device success rate (P = .63), the need for postdilatation (P = .82), and composite adverse events (P = .98) compared with preimplantation balloon valvuloplasty. Subgroup analysis for balloon-expandable valves showed lower need for balloon postdilatation (risk ratio [RR], 0.63 [0.47, 0.84]; P = .002; I2 , 0%) in direct TAVR group but higher incidence of acute kidney injury (RR, 3.23 [1.25, 8.40]; P = .02; I2 , 0%) and major/life-threatening bleeding (RR, 1.54 [1.17, 2.02]; P = .002; I2 , 0%). Subgroup analysis for the RCTs alone and RCTs + propensity-matched cohorts showed similar device success and composite adverse events in both groups. However, pooled RCTs showed a higher need for balloon postdilatation in direct TAVR (RR, 1.83 [1.03, 3.24]; P = .04; I2 , 0%). CONCLUSION: Direct TAVR has similar efficacy and safety to preimplantation balloon valvuloplasty. However, better-designed RCTs are required before drawing a definite conclusion.

BACKGROUND: Breast reconstruction can ease the psychological burden in breast cancer patients that have undergone mastectomy. The aim of our study is to collect the latest evidences to summarize whether pedicled TRAM (pTRAM) is non-inferior in terms of patient satisfaction and complications to free TRAM (fTRAM) so that it may be used in region with limited resources. METHODS: We performed a comprehensive search on studies that compared pTRAM and fTRAM flap from several databases. RESULTS: There are six studies included. Despite the diversity among the correspondents, all studies demonstrated no difference between the two groups regarding patient overall satisfaction. However, two studies found that pTRAM had lower abdominal well-being score, three found higher abdominal related morbidity, while fTRAM had a higher overall cost. Pooled mean difference was not significant on all BREAST-Q subscales, meaning that pTRAM and fTRAM has a similar outcome. CONCLUSION: Although pTRAM is non-inferior in terms of satisfaction to fTRAM, it is associated with a more frequent complication. It may be used in developing countries that lack facilities and limited by cost. However, pTRAM should be done by experienced surgeons to minimize the risk of complications.

INTRODUCTION: A prolonged P-wave duration (PWD) in sinus rhythm pre-ablation has been hypothesized to be a non-invasive ECG marker associated with increased atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI). This systematic review and meta-analysis will assess the latest evidence on the association of prolonged PWD pre-ablation with AF recurrence after PVI. HYPOTHESIS: Prolonged PWD pre-ablation is associated with AF recurrence after PVI. METHODS: The inclusion criteria for this study are all cohort studies that assess prolonged PWD on ECG during sinus rhythm pre-ablation and its association with AF recurrence in post-PVI patients. RESULTS: There were 1,482 patients with AF post-PVI from twelve cohort studies. The cut-off points for prolonged PWD ranges from >120 ms to >150 ms. Meta-analysis on six studies showed a pooled mean difference of PWD in subjects with recurrent AF and non-recurring AF was 12.54 ms [8.76-16.31], p < 0.001; I2 78%. Pooled odds ratio was 4.17 [2.10-8.31], p < 0.001; I2 72% and pooled hazard ratio was 1.93 [1.10-3.39], p = 0.02; I2 80%. Upon subgroup analysis, the association between prolonged PWD and AF recurrence was significant in signal-averaged ECG, 12-lead ECG, paroxysmal AF, >120-130 ms, and >140-150 ms PWD cut-off point subgroups. CONCLUSION: These findings suggest that prolonged PWD with a cutoff of >120 ms to >150 ms in sinus rhythm before ablation may be associated with AF recurrence after PVI regardless of age, gender, left atrial size, and the presence of structural heart disease. We also encouraged further studies that investigate predicting models to include prolonged PWD as one of their parameters.

BACKGROUND: Contact-force sensing catheter is widely used for catheter ablation, however, it did not take account of radiofrequency power. Ablation index (AI) is a novel marker incorporating contact force-time-power, was shown to be reliable in predicting lesion size and depth for radiofrequency delivery. We aimed to assess the latest evidence on ablation index guided procedure versus conventional ablation procedure. METHODS: We performed a comprehensive search on topic that assesses ablation index guided procedure versus conventional procedures from inception up until February 2019 through PubMed, EuropePMC, EBSCOhost, Cochrane Central Database, and ClinicalTrials.gov. RESULTS: A total of 1727 subjects from five studies were included. 12 months' incidence of AF/AT/AFL was lower in ablation index guided with an OR of 0.35 [0.17, 0.73], pâ¯=â¯0.005; I2 58%. Upon sensitivity analysis by removing a study, heterogeneity decreased to 0% with OR of 0.26 [0.15, 0.46], pâ¯<â¯0.001. First-pass isolation has a pooled OR of 11.29 [4.68, 27.20], pâ¯<â¯0.001; I2 58%. Pooled OR for acute pulmonary vein reconnection was 0.43 [0.29, 0.64], pâ¯<â¯0.001; I2 46%. AI group has a shorter fluoroscopy time of MD -1.62 [-2.62, -0.62] minutes, pâ¯=â¯0.001; I2 51% and total ablation time MD -9.96 [-17.16, -2.76] minutes, pâ¯<â¯0.001; I2 95%. Total procedural time and complication rate were similar. CONCLUSION: Ablation index guided procedure resulted in a significantly lower incidence of AF/AT/AFL, shorter fluoroscopy time, and total ablation time. First-pass isolation was higher in AI group and acute PVR was lower in AI group. Ablation-index guided procedure has a similar safety profile to conventional ablation.
RESUMO
BACKGROUND: Controversies surrounded the management of asymptomatic Brugada syndrome. Prognostication using electrophysiology study (EPS) is disputable. Non-invasive parameters may be a valuable additional tool for risk stratification. We aim to evaluate the use markers of ventricular repolarization including Tpeak-to-Tend (TpTe), Tpe Dispersion, TpTe/QT ratio, and QTc interval as additional non-invasive electrocardiography parameters for predicting ventricular tachycardia/fibrillation in patients with Brugada syndrome. METHODS: We performed a comprehensive search on TpTe, Tpe Dispersion, TpTe/QT ratio, and QTc interval as a predictor for ventricular tachycardia(VT)/fibrillation(VF)/aborted sudden cardiac death/appropriate ICD shock in patients with Brugada syndromes up until October 2018. RESULTS: We included ten studies in the qualitative synthesis and eight studies in meta-analysis. There were a total of 2126 subjects from ten studies. We found that TpTe interval (mean difference 11.97â¯mâ¯s [5.02-18.91]; pâ¯<â¯0.001; I2 80% possibly on ≥80-100â¯mâ¯s and maximum QTc interval (mean difference 11.42â¯mâ¯s [5.90-16.93], pâ¯<â¯0.001; I2 28%) were the most potential ECG parameters to predict VT/VF/AT/SCD. Tpe dispersion and TpTe/QT ratio have a high heterogeneity. Upon sensitivity analysis, there is no single study found to markedly affect heterogeneity of Tpe dispersion and TpTe/QT ratio. Removal of a study reduced maximum QTc interval heterogeneity to 0%. CONCLUSIONS: Measurement of TpTe interval, Tp-e dispersion, TpTe/QT ratio, and QTc interval on ECG emerge as a promising prognostication tool which needs further investigations with a more standardized method, outcome, and cut-off points. As for now, only maximum QTc interval has a reliable result with low heterogeneity sufficiently reliable for prognostication.
RESUMO
Background: Endoscopic third ventriculostomy (ETV) is a procedure that involves devising an opening in the third ventricle floor, allowing cerebrospinal fluid to flow into the prepontine cistern and the subarachnoid space. Third ventricular floor bowing (TVFB) serves as an indicator of intraventricular obstruction in hydrocephalus and existence of pressure gradient across third ventricular floor, which is the prerequisite of a successful ETV. Objective: In this systematic review and meta-analysis, we aimed to synthesize the latest evidence on the TVFB as a marker for surgical success in patients undergoing ETV. Material and Methods: We performed a comprehensive search on topics that assesses the association of TVFB with the surgical success in patients undergoing ETV from several electronic databases. Results: There was a total of 568 subjects from six studies. TVFB was associated with 85% (81-88%) ETV success. TVFB was associated with OR 4.13 [2.59, 6.60], P < 0.001; I2: 6% for ETV success. Subgroup analysis on pediatric patients showed 86% (82-91%) success rate. In terms of value for ETV success compared to ETV Success Score (ETVSS), a high ETVSS does not significantly differ (P = 0.31) from TVFB and TVFB was associated with OR 3.14 [1.72, 5.73], P < 0.001; I2: 69% compared to intermediate/moderate ETVSS. Funnel plot analysis showed an asymmetrical funnel plot due to the presence of an outlier. Upon sensitivity analysis by removing the outlier, the OR was 3.62 [2.22, 5.89], P < 0.001; I2: 0% for successful surgery in TVFB. Conclusions: TVFB was associated with an increased rate of successful surgery in adults and children undergoing ETV.

BACKGROUND: We aimed to synthesize the latest evidence on the efficacy and safety of decompression alone compared to decompression with fusion in patients with lumbar spondylolisthesis. We also aimed to evaluate factors affecting the efficacy and complications. METHODS: A systematic literature search was conducted using PubMed, Scopus, Europe PMC, Cochrane Central Database, and ClinicalTrials.gov. The main outcome was improvement in Oswestry Disability Index (ODI). The secondary outcome was back pain and leg pain improvement, complications, reoperation rate, duration of surgery, length of hospital stay, and blood loss. RESULTS: There were 3993 patients from 13 studies. Decompression with fusion was associated with greater reduction in ODI (mean difference 4.04 [95% CI 0.95, 7.13], P = 0.01) compared to decompression alone. Greater reduction in back (standardized mean difference [SMD] 0.27 [95% CI 0.00, 0.53], P = 0.05) and leg pain (SMD 0.13 [95% CI 0.06, 0.21], P < 0.001) was observed in the decompression with fusion group. Complications were similar in the 2 groups (OR 0.60 [95% CI 0.34, 1.04], P = 0.07). The reoperation rate was similar in both groups (P = 0.54). Decompression alone resulted in shorter duration of surgery (mean difference -85.18 minutes [95% CI -122.79, -47.57], P < 0.001), less blood loss (mean difference -262.65 mL [95% CI -313.45, -211.85], P < 0.001), and shorter hospital stay (mean difference -2.64 days [95% CI -3.58, -1.70], P < 0.001). Empirical Bayes random-effects meta-regression showed that the rate of complication was influenced by age (coefficient 0.172, P = 0.004). CONCLUSION: Decompression with fusion had greater efficacy than decompression alone but was associated with more blood loss, lengthier surgery, and hospitalization. In terms of complications, decompression alone may be beneficial in younger patients. (PROSPERO CRD42020211904) LEVEL OF EVIDENCE: 2A.
RESUMO
INTRODUCTION: Warts can be difficult to treat and progressing to chronic and resistant disease. Several studies have reported the successful application of mumps-measles-rubella (MMR) vaccine resulting in clearance of warts via immunomodulation and induction of immune system. METHODS: We performed a comprehensive search on the role of intralesional MMR in warts from several electronic databases. Complete response is defined as complete clearance of warts lesion. RESULTS: There were a total of 425 subjects from five studies. Intralesional injection of MMR was associated with an increased complete response (OR 9.43 [5.78, 15.37], p < .001; I2: 5%, p = .38). Subgroup analysis on patients receiving injection for every 2 weeks for a maximum of five injections revealed an OR of 11.70 [6.40, 21.38], p < .001; I2: 20%, p = .29. Patients receiving intralesional MMR were associated with a lower partial response (OR 0.54 [0.33, 0.88], p = .01; I2: 0%, p = .66). Intralesional MMR was associated with a reduced no-response (OR 0.16 [0.06, 0.43], p < .001; I2: 69%, p = .01). Funnel plot analysis for complete response was asymmetrical, indicating the risk of publication bias. There were statistically significant small-study effects for intralesional MMR on complete response upon analysis using Harbord's test (p = .047). Grading of Recommendations Assessment, Development and Evaluation (GRADE) assessment showed that intralesional MMR injection has high level of certainty (quality of evidence) for complete response in warts with an absolute increase of 505 per 1000. CONCLUSION: Intralesional MMR injection was associated with a higher complete response and lower no-response with a high level of certainty.

PURPOSE: We aimed to perform a systematic literature search on the latest evidence of the role of statin in reducing diabetic retinopathy and its need for intervention. METHODS: A comprehensive search on cohort studies/clinical trials that assess statins and diabetic retinopathy up until August 2019 was performed. The outcome measured was the incidence of diabetic retinopathy and its need for intervention. RESULTS: There were 558.177 patients from six studies. Statin was associated with a lower incidence of diabetic retinopathy (hazard ratio: 0.68 (0.55, 0.84), p < 0.001; I2: 95%). For the subtypes of diabetic retinopathy, statin lowers the incidence of proliferative diabetic retinopathy (hazard ratio: 0.69 (0.51, 0.93), p = 0.01; I2: 90%), non-proliferative diabetic retinopathy (hazard ratio: 0.80 (0.66, 0.96), p = 0.02; I2: 93%), and diabetic macular edema (hazard ratio: 0.56 (0.39, 0.80), p = 0.002; I2: 82%). Statin was associated with a reduced need for retinal laser treatment with a hazard ratio of 0.70 (0.64, 0.76) (p < 0.001; I2: 0%), intravitreal injection with a hazard ratio of 0.82 (0.79, 0.85) (p < 0.001; I2: 0%), and vitrectomy with a hazard ratio of 0.64 (0.48, 0.85) (p < 0.001; I2: 75%). Overall, statin was associated with a reduced need for intervention for diabetic retinopathy with a hazard ratio of 0.72 (0.64, 0.80) (p < 0.001; I2: 73%). The regression-based Egger's test showed statistically significant small-study effects for non-proliferative diabetic retinopathy (p = 0.011) outcomes. CONCLUSION: Statin was associated with a decreased risk of diabetic retinopathy and its subtypes. Statin also reduced the need for intervention with retinal laser treatment, intravitreal injection, and vitrectomy.

ABSTARCT: AIMS: We aimed to assess the dose-response relationship between triglyceride-glucose (TyG) index and the incidence of type 2 diabetes mellitus (T2DM). METHODS: We performed a comprehensive systematic literature search using PubMed, Scopus, and Embase for records published from inception until 9 February 2021. The effect estimates were reported as relative risks (RRs). RESULTS: 270,229 subjects from 14 studies were included in this systematic review and meta-analysis. The pooled incidence of T2DM was 9%. Meta-regression analysis indicates that baseline age (coefficient: 0.67, p = 0.026), drinking (coefficient: 0.03, p = 0.035), and HDL (coefficient: -0.89, p = 0.035) affected the incidence of T2DM in future. High TyG index was associated with increased incidence of T2DM in pooled unadjusted (RR 4.68 [3.01, 7.29], p < 0.001; I2: 96.6%) and adjusted model (adjusted RR 3.54 [2.75, 4.54], p < 0.001; I2: 83.7%). Dose-response meta-analysis for the adjusted RR showed that the linear association analysis was not significant per 0.1 increase in TyG index (RR 1.01 [0.99, 1.03], p = 0.223). There is a non-linear trend (p < 0.001) for the association between TyG index and incidence of T2DM. The dose-response curve became increasingly steeper at TyG index above 8.6. CONCLUSIONS: TyG index was associated with the incidence of T2DM in a non-linear fashion.

PURPOSE: Intravitreal ranibizumab (RNB) and dexamethasone intravitreal implant (DII) were developed in the recent past and has been widely used for macular edema secondary to BRVO. We aimed to assess the efficacy and safety of intravitreal ranibizumab (RNB) compared to dexamethasone intravitreal implant (DII) in patients with macular edema secondary to branch retinal vein occlusion (BRVO). METHODS: We performed a comprehensive search on topics that assess RNB and DII in patients with macular edema secondary to BRVO from several electronic databases. RESULTS: There were 678 subjects from five studies. Ranibizumab was associated with a greater increase in best-corrected visual acuity (BCVA; mean difference 9.13, I2: 0%) compared to DII. Ranibizumab also demonstrated a greater ⩾10 (OR 2.76, I2: 0%) and ⩾15 letters (OR 2.78, I2: 0%) gain. RNB has better BCVA (logMAR scale) improvement at 6 months' follow up (mean difference -0.15, I2: 64%) in favor of RNB. Higher IOP was found in DII group on follow-up (mean difference -2.92, I2: 89%) and RNB has lesser IOP ⩾10 mmHg increase compared to DII (OR 0.08, I2: 0%). Cataract formation and/or progression was less in RNB (OR 0.53, I2: 75%). The need for rescue laser was similar the two groups. CONCLUSION: Intravitreal RNB was more effective with less pronounced effect on IOP and cataract formation and/or progression compared to DII for patients with macular edema secondary to BRVO.

OBJECTIVE: PulseRider is a novel self-expanding nickel-titanium (nitinol) stent for treatment of wide-necked aneurysms, which is commonly located at the arterial branches in the brain. This systematic review and meta-analysis aims to assess the efficacy and safety of PulseRider for treatment of wide-necked intracranial aneurysm. METHOD: We performed a systematic literature search on articles that evaluate the efficacy and safety of PulseRider-assisted coiling of the wide-necked aneurysm from several electronic databases. The primary endpoint was adequate occlusion, defined as Raymond-Roy Class I + Raymond-Roy Class II upon immediate angiography and at six-month follow-up. RESULTS: There were a total of 157 subjects from six studies. The rate of adequate occlusion on immediate angiography was 90% (95% CI, 85%-94%) and 91% (95% CI, 85%-96%) at six-month follow-up. Of these, Raymond-Roy Class I can be observed in 48% (95% CI, 41%-56%) of aneurysms immediately after coiling, and 64% (95% CI, 55%-72%) of aneurysms on six-month follow-up. Raymond-Roy Class II was found in 30% (95% CI, 23%-37%) of aneurysms immediately after coiling, and 25% (17-33) after six-month follow-up. Complications occur in 5% (95% CI, 1%-8%) of the patients. There were three intraoperative aneurysm rupture, three thrombus formation, three procedure-related posterior cerebral artery strokes, one vessel dissection, and one delayed device thrombosis. There was no procedure/device-related death. CONCLUSIONS: PulseRider-assisted coiling for treatment of patients with wide-necked aneurysm reached 90% adequate occlusion rate that rises up to 91% at sixth month with 5% complication rate.

OBJECTIVE: The aim of this meta-analysis was to synthesize the latest evidence on the effect of probucol on the incidence of contrast-induced nephropathy (CIN) in patients undergoing coronary angiography (CAG)/percutaneous coronary intervention (PCI). METHODS: A systematic literature search of PubMed, ScienceDirect, EuropePMC, ProQuest, and Clinicaltrials. gov was performed to retrieve studies that assessed probucol and CIN in CAG/PCI. RESULTS: Four studies that compared probucol with hydration alone, comprising 1270 subjects, were identified and analyzed. There was no significant difference between probucol and control groups in the baseline level of creatinine and at 48 hours; however, a significant difference was observed at 72 hours (mean difference: -3.87 µmol/L; 95% confidence interval [CI]: -6.58, -1.15; p=0.005). The meta-analysis indicated that probucol did not reduce the CIN incidence (odds ratio [OR]: 0.46; 95% CI: 0.20, 1.08; p=0.08). After performing a leave-one-out sensitivity analysis, removal of a study resulted in a lower risk of CIN (OR: 0.33; 95% CI: 0.19, 0.56; p<0.001). Probucol did not reduce the CIN incidence in a pooled adjusted effect estimate (OR: 0.75; 95% CI: 0.15, 3.87; p=0.73). There was no significant difference in the rate of major adverse events between the 2 groups (OR: 0.39; 95% CI: 0.05, 3.05; p=0.37). Funnel plot results were asymmetrical, indicating possible publication bias. Grading of Recommendations, Assessment, Development and Evaluations qualification demonstrated a low and very low certainty of evidence in unadjusted and adjusted effect estimates, respectively. CONCLUSION: Probucol did not reduce the incidence of CIN; however, due to the low certainty of evidence, further study is required for a definite conclusion. Although the p value was not significant, the confidence interval showed a nonsignificant trend toward benefit. However, this trend might have been due to publication bias.

OBJECTIVE: In this study, we aimed to compare the minimally invasive surgery (MIS) instrumented fusion ± decompression versus conventional open surgery (COS) instrumented fusion ± decompression for the treatment of spinal metastases. METHODS: We performed a systematic literature search through PubMed, Scopus, Europe PMC (PubMed Central), and Cochrane Central Database using the keywords "minimal invasive surgery" OR "minimally invasive surgery" OR "mini-open" AND "conventional open surgery" OR "traditional open surgery" OR "open surgery" AND "spinal metastasis". The outcomes of interest were complications, neurologic improvement, length of stay, intraoperative blood loss, transfusion rate, and operative duration. RESULTS: There were a total of 8 studies comprising 486 patients. Complications were less frequent in MIS compared with COS (odds ratio [OR], 0.51; 95% confidence interval [CI], 0.30-0.84; P = 0.01; I2 = 0%). Major complications related to surgery were less in the MIS group (OR, 0.42; 95% CI, 0.21-0.84; P = 0.01; I2 = 0%). The rate of neurologic improvement was similar in both groups (OR, 1.01; 95% CI, 0.64-1.59; P = 0.95; I2 = 0%). MIS was associated with less blood loss (mean difference, -690.00 mL; 95% CI, -888.31 to -491.69; P < 0.001; I2 = 56%), and lower transfusion rate compared with COS (OR, 0.27; 95% CI, 0.11-0.66; P = 0.004; I2 = 50%). Length of surgery was similar in both groups (mean difference, -12.49 minutes; 95% CI, -45.93 to 20.95; P = 0.46; I2 = 86%). MIS resulted in shorter length of stay compared with COS (mean difference -3.58 days; 95% CI, -6.90 to -0.26; P = 0.03; I2 = 89%). CONCLUSIONS: MIS was associated with lower complications, blood loss, transfusion rate, and shorter length of stay with a similar rate of neurologic improvement and length of surgery compared with COS.

INTRODUCTION: Older adults are indisputably struck hard by the coronavirus disease 2019 (COVID-19) pandemic. The main objective of this meta-analysis is to establish the association between delirium and mortality in older adults with COVID-19. METHODS: Systematic literature searches of PubMed, Embase, and Scopus databases were performed up until 28 November 2020. The exposure in this study was the diagnosis of delirium using clinically validated criteria. Delirium might be in-hospital, at admission, or both. The main outcome was mortality defined as clinically validated non-survivor/death. The effect estimates were reported as odds ratios (ORs) and adjusted odds ratios (aORs). RESULTS: A total of 3,868 patients from 9 studies were included in this systematic review and meta-analysis. The percentage of patients with delirium was 27% [20%, 34%]. Every 1 mg/L increase in CRP was significantly associated with 1% increased delirium risk (OR 1.01 [1.00. 1.02], p=0.033). Delirium was associated with mortality (OR 2.39 [1.64, 3.49], p<0.001; I2: 82.88%). Subgroup analysis on delirium assessed at admission indicate independent association (OR 2.12 [1.39, 3.25], p<0.001; I2: 82.67%). Pooled adjusted analysis indicated that delirium was independently associated with mortality (aOR 1.50 [1.16, 1.94], p=0.002; I2: 31.02%). Subgroup analysis on delirium assessed at admission indicate independent association (OR 1.40 [1.03, 1.90], p=0.030; I2: 35.19%). Meta-regression indicates that the association between delirium and mortality were not significantly influenced by study-level variations in age, sex [reference: male], hypertension, diabetes, and dementia. CONCLUSION: The presence of delirium is associated with increased risk of mortality in hospitalized older adults with COVID-19.

OBJECTIVE: This systematic review and meta-analysis aimed to evaluate whether dyslipidemia affects the mortality and severity of COVID-19, we also aimed to evaluate whether other comorbidities influence the association. METHODS: A systematic literature search using PubMed, Embase, and EuropePMC was performed on 8 October 2020. This study's main outcome is a poor composite outcome, comprising of mortality and severe COVID-19. RESULTS: There were 9 studies with 3663 patients. The prevalence of dyslipidemia in this pooled analysis was 18% (4%-32%). Dyslipidemia was associated with increased composite poor outcome (RR 1.39 [1.02, 1.88], P = .010; I 2: 56.7%, P = .018). Subgroup analysis showed that dyslipidemia was associated with severe COVID-19 (RR 1.39 [1.03, 1.87], P = .008; I 2: 57.4%, P = .029). Meta-regression showed that the association between dyslipidemia and poor outcome varies by age (coefficient: -0.04, P = .033), male gender (coefficient: -0.03, P = .042), and hypertension (coefficient: -0.02, P = .033), but not diabetes (coefficient: -0.24, P = .135) and cardiovascular diseases (coefficient: -0.01, P = .506). Inverted funnel-plot was relatively symmetrical. Egger's test indicates that the pooled analysis was not statistically significant for small-study effects (P = .206). CONCLUSION: Dyslipidemia potentially increases mortality and severity of COVID-19. The association was stronger in patients with older age, male, and hypertension.PROSPERO Registration Number: CRD42020213491.
RESUMO
BACKGROUND: Recent evidence showed that the characteristics and outcome of those with de novo heart failure (HF) and acutely decompensated chronic heart failure (ADCHF) were different. We aimed to perform a comprehensive search on the clinical characteristics and outcome of patients with de novo HF and ADCHF. METHODS: We performed a comprehensive search on de novo/new onset acute HF vs ADCHF from inception up until December 2019. RESULTS: There were 38320 patients from 15 studies. De novo HF were younger and, had less prevalent hypertension, diabetes mellitus, ischaemic heart disease, chronic obstructive pulmonary disease, atrial fibrillation, and history of stroke/transient ischaemic attack compared to ADCHF. Five studies showed a lower NT-proBNP in de novo HF patients, while one study showed no difference. Valvular heart disease as aetiology of heart failure was less frequent in de novo HF, and upon sensitivity analysis, hypertensive heart disease was more frequent in de novo HF. As for precipitating factors, ACS (OR 2.42; I2:89%) was more frequently seen in de novo HF, whereas infection was less frequently (OR 0.69; I2:32%) in ADCHF. De novo HF was associated with a significantly lower 3-month mortality (OR 0.63; I2:91%) and 1-year (OR 0.59; I2:59%) mortality. Meta-regression showed that 1-year mortality did not significantly vary with age (p = .106), baseline ejection fraction (p = .703), or HF reduced ejection fraction (p = .262). CONCLUSION: Risk factors, aetiology, and precipitating factors of HF in de novo and ADCHF differ. De novo HF also had lower 1-year mortality and 3-month mortality compared to ADCHF.
