Comparison of SYNTAX score strata effects of percutaneous and surgical revascularization trials: A meta-analysis. J Thorac Cardiovasc Surg 2023; 165:1405-1413.e13. [PMID: 34176619 PMCID: PMC8805094 DOI: 10.1016/j.jtcvs.2021.05.036] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 04/27/2021] [Accepted: 05/13/2021] [Indexed: 02/08/2023]
Abstract
OBJECTIVES The evidence supporting the use of the Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery (SYNTAX) score for risk stratification is controversial. We performed a systematic review and meta-analysis of all the randomized controlled trials comparing percutaneous coronary intervention versus coronary artery bypass grafting that reported their outcomes stratified by SYNTAX score, focusing on between-strata comparisons. METHODS A systematic review of MEDLINE, EMBASE, Cochrane Library databases was performed. Incidence rate ratios were pooled with a random effect model. Between-group statistical heterogeneity according to accepted SYNTAX score tertiles was computed in the main analysis. Ratios of incidence rate ratios were computed to appraise between-strata effect, as sensitivity analysis. Primary and secondary outcomes were major adverse cardiac and cerebrovascular events and all-cause mortality, respectively. Separate sub-analyses were performed for left main and multivessel disease. RESULTS From 425 citations, 6 trials were eventually included (8269 patients [4134 percutaneous coronary interventions, 4135 coronary artery bypass graftings]; mean follow-up: 6.2 years [range: 3.8-10]). Overall, percutaneous coronary intervention was associated with a significant increase in major adverse cardiac and cerebrovascular events (incidence rate ratio, 1.39, 95% confidence interval, 1.27-1.51) and nonsignificant increase in all-cause mortality (incidence rate ratio, 1.17, 95% confidence interval, 0.98-1.40). There was no significant statistical heterogeneity of treatment effect by SYNTAX score for major adverse cardiac and cerebrovascular events or mortality (P = .40 and P = .34, respectively). Results were consistent also for patients with left main and multivessel disease (major adverse cardiac and cerebrovascular events: P = .85 in left main, P = .78 in multivessel disease 0.78; mortality: P = .12 in left main; P = .34 in multivessel disease). Results of analysis based on ratios of incidence rate ratios were consistent with the main analysis. CONCLUSIONS No significant association was found between SYNTAX score and the comparative effectiveness of percutaneous coronary intervention and coronary artery bypass grafting. These findings have implications for clinical practice, future guidelines, and the design of percutaneous coronary intervention versus coronary artery bypass grafting trials.

Abstract
Abstract
Aim
To compare the results of stem cell-enhanced fat grafting to autologous fat grafting for face reconstruction.
Method
A systematic review and meta-analysis were carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Guidelines, and an electronic search was carried out to identify all Randomised Controlled Trials (RCTs), case control studies, and cohort studies comparing the outcomes of stem cell-enrichment fat grafting versus routine fat grafting for facial reconstruction. The primary outcome measures were volume retention and infection rate. Secondary outcome measures included post-surgery patient satisfaction, redness and swelling, fat necrosis, cysts, and operation time. For the analysis, fixed and random effects modelling were utilised.
Results
Eight studies with a total of 275 participants were assessed. In terms of mean volume retention, there was a significant difference between the stem cell-enrichment fat grafting and routine grafting groups (standardised Mean Difference [MD] = 2.49, P 0.00001). However, there was no significant difference in infection rates between the two groups (OR = 0.36, P = 0.30). Except for the operation duration, which was shorter in the latter, the intervention group had similar results to the control group for all secondary outcomes.
Conclusions
When compared to conventional fat grafting, stem cell-enriched fat grafting is a better alternative for facial reconstruction surgery since it enhances mean volume retention and does not worsen patient satisfaction or surgical complications.

Abstract
Abstract
Background
TAVI has emerged as an attractive treatment modality based on promising recent trial data. Patients with BAV, a commonly encountered clinical condition have largely been excluded from a majority of trials.
Purpose
Elderly patients with BAV and severe AS are increasingly encountered in clinical practice. This meta-analysis compares clinical outcomes between bicuspid and tricuspid AV patients to address the current knowledge-gap and identify optimal management strategies of these patients.
Methods
A comprehensive literature search was performed in PubMed, Embase, and Cochrane to identify the available observational studies comparing outcomes of TAVI in BAV and TAV patients. Summary effects were calculated using a DerSimonian and Laird random-effects model as odds ratio with 95% confidence intervals for all the clinical endpoints.
Results
16 Observational studies met inclusion criteria, comprising 10,053 patients with BAV and 173,307 patients with TAV that underwent TAVI. No significant differences in 30-day and long-term mortality rates were observed. Patients with BAV had an increased risk of stroke (OR 1.23; 95% CI [1.06–1.44], p=0.007), re-intervention (OR 1.90; 95% CI [1.15–3.15], p=0.01), paravalvular leak (OR 1.42; 95% CI [1.25–1.61], p<0.ehab724.22251), conversion to open surgery (OR 1.93; 95% CI [1.21–3.07], p=0.006), and new pacemaker implantation (1.57; 95% CI (1.06 - 2.33, p=0.02). Adverse event rates are lower with the use of newer generation of valves. No significant difference in major vascular complications, major bleeding, or incidence of AKI was noted.
Conclusions
Complication rates for BAV TAVI are higher, but mortality is similar to TAV TAVI indicating TAVI is an appropriate alternative for intermediate-high risk patients with BAV. A better understanding of valve anatomy, physician expertise, the use of newer-generation valves can help reduce these complications.

Abstract
OBJECTIVES Previous reports have found females are a higher risk of morbidity and mortality following isolated coronary artery bypass grafting (CABG). Here, we describe the differences in outcomes following isolated CABG between males and females. METHODS Following a systematic literature search, studies reporting sex-related outcomes following isolated CABG were pooled in a meta-analysis performed using the generic inverse variance method. The primary outcome was operative mortality. Secondary outcomes included rates of stroke, repeat revascularization, myocardial infarction, major adverse cardiac events, and late mortality. Subgroup analyses were performed for studies published before and after the year 2000 and for the type of risk adjustment. RESULTS Eighty-four studies were included with a total of 903 346 patients. Females were at higher risk for operative mortality (odds ratio: 1.77, 95% confidence interval [CI]: 1.64-1.92, P < 0.001). At subgroup analysis, there was no difference in operative or late mortality between studies published prior and after 2000 or between studies using risk adjustment. Females were at a higher risk of late mortality (incidence rate ratio [IRR]: 1.16, 95% CI: 1.06-1.26, P < 0.001), major adverse cardiac events (IRR: 1.40, 95% CI: 1.19-1.66, P < 0.001), myocardial infarction (IRR: 1.28, 95% CI: 1.13-1.45, P < 0.001) and stroke (IRR: 1.31, 95% CI: 1.15-1.51, P > 0.001) but not repeat revascularization (IRR: 0.99, 95% CI: 0.76-1.29, P = 0.95). The use of the off-pump technique or multiple arterial grafts was not associated with the primary outcome. CONCLUSIONS Females undergoing CABG are at higher risk for operative and late mortality as well as postoperative events including major adverse cardiac events, myocardial infarction and stroke.

Abstract
Background Quality of the peer‐review process has been tested only in small studies. We describe and summarize the randomized trials that investigated interventions aimed at improving peer‐review process of biomedical manuscripts. Methods and Results All randomized trials comparing different peer‐review interventions at author‐, reviewer‐, and/or editor‐level were included. Differences between traditional and intervention‐modified peer‐review processes were pooled as standardized mean difference (SMD) in quality based on the definitions used in the individual studies. Main outcomes assessed were quality and duration of the peer‐review process. Five‐hundred and seventy‐five studies were retrieved, eventually yielding 24 randomized trials. Eight studies evaluated the effect of interventions at author‐level, 16 at reviewer‐level, and 3 at editor‐level. Three studies investigated interventions at multiple levels. The effects of the interventions were reported as mean change in review quality, duration of the peer‐review process, acceptance/rejection rate, manuscript quality, and number of errors detected in 13, 11, 5, 4, and 3 studies, respectively. At network meta‐analysis, reviewer‐level interventions were associated with a significant improvement in review quality (SMD, 0.20 [0.06 to 0.33]), at the cost of increased duration of the review process (SMD, 0.15 [0.01 to 0.29]), except for reviewer blinding. Author‐ and editor‐level interventions did not significantly impact peer‐review quality and duration (respectively, SMD, 0.17 [−0.16 to 0.51] and SMD, 0.19 [−0.40 to 0.79] for quality, and SMD, 0.17 [−0.16 to 0.51] and SMD, 0.19 [−0.40 to 0.79] for duration). Conclusions Modifications of the traditional peer‐review process at reviewer‐level are associated with improved quality, at the price of longer duration. Further studies are needed.

Abstract
Background Several randomized trials have compared the patency of coronary artery bypass conduits. All of the published studies, however, have performed pairwise comparisons and a comprehensive evaluation of the patency rates of all conduits has yet to be published. We set out to investigate the angiographic patency rates of all conduits used in coronary bypass surgery by performing a network meta-analysis of the current available randomized evidence. Methods and Results A systematic literature search was conducted for randomized controlled trials comparing the angiographic patency rate of the conventionally harvested saphenous vein, the no-touch saphenous vein, the radial artery (RA), the right internal thoracic artery, or the gastroepiploic artery. The primary outcome was graft occlusion. A total of 4160 studies were retrieved of which 14 were included with 3651 grafts analyzed. The weighted mean angiographic follow-up was 5.1 years. Compared with the conventionally harvested saphenous vein, both the RA (incidence rate ratio [IRR] 0.54; 95% CI, 0.35-0.82) and the no-touch saphenous vein (IRR 0.55; 95% CI, 0.39-0.78) were associated with lower graft occlusion. The RA ranked as the best conduit (rank score for RA 0.87 versus 0.85 for no-touch saphenous vein, 0.23 for right internal thoracic artery, 0.29 for gastroepiploic artery, and 0.25 for the conventionally harvested saphenous vein). Conclusions Compared with the conventionally harvested saphenous vein, only the RA and no-touch saphenous vein grafts are associated with significantly lower graft occlusion rates. The RA ranks as the best conduit. Registration URL: https://www.crd.york.ac.uk/prospero; Unique identifier: CRD42020164492.

Abstract
IMPORTANCE Mortality is a common outcome in trials comparing percutaneous coronary intervention (PCI) with coronary artery bypass grafting (CABG). Controversy exists regarding whether all-cause mortality or cardiac mortality is preferred as a study end point, because noncardiac mortality should be unrelated to the treatment. OBJECTIVE To evaluate the difference in all-cause and cause-specific mortality in randomized clinical trials (RCTs) comparing PCI with CABG for the treatment of patients with coronary artery disease. DATA SOURCES MEDLINE (1946 to the present), Embase (1974 to the present), and the Cochrane Library (1992 to the present) databases were searched on November 24, 2019. Reference lists of included articles were also searched, and additional studies were included if appropriate. STUDY SELECTION Articles were considered for inclusion if they were in English, were RCTs comparing PCI with drug-eluting or bare-metal stents and CABG for the treatment of coronary artery disease, and reported mortality and/or cause-specific mortality. Trials of PCI involving angioplasty without stenting were excluded. For each included trial, the publication with the longest follow-up duration for each outcome was selected. DATA EXTRACTION AND SYNTHESIS For data extraction, all studies were reviewed by 2 independent investigators, and disagreements were resolved by a third investigator in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline. Data were pooled using fixed- and random-effects models. MAIN OUTCOMES AND MEASURES The primary outcomes were all-cause and cause-specific (cardiac vs noncardiac) mortality. Subgroup analyses were performed for PCI trials using drug-eluting vs bare-metal stents and for trials involving patients with left main disease. RESULTS Twenty-three unique trials were included involving 13 620 unique patients (6829 undergoing PCI and 6791 undergoing CABG; men, 39.9%-99.0% of study populations; mean age range, 60.0-71.0 years). The weighted mean (SD) follow-up was 5.3 (3.6) years. Compared with CABG, PCI was associated with a higher rate of all-cause (incidence rate ratio, 1.17; 95% CI, 1.05-1.29) and cardiac (incidence rate ratio, 1.24; 95% CI, 1.05-1.45) mortality but also noncardiac mortality (incidence rate ratio, 1.19; 95% CI, 1.00-1.41). CONCLUSIONS AND RELEVANCE Percutaneous coronary intervention was associated with higher all-cause, cardiac, and noncardiac mortality compared with CABG at 5 years. The significantly higher noncardiac mortality associated with PCI suggests that even noncardiac deaths after PCI may be procedure related and supports the use of all-cause mortality as the end point for myocardial revascularization trials.

Abstract
OBJECTIVES The optimal revascularization strategy for patients with ischaemic left ventricular systolic dysfunction (iLVSD) remains controversial. We aimed to compare percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) and medical therapy (MT) in a network meta-analysis. METHODS All randomized controlled trials and observational studies comparing any combination of PCI, CABG and MT in patients with iLVSD were analysed in a frequentist network meta-analysis (generic inverse variance method). Primary outcome was mortality at longest available follow-up. Secondary outcomes were cardiac death, stroke, myocardial infarction (MI) and repeat revascularization (RR). RESULTS Twenty-three studies were included (n = 23 633; 4 randomized controlled trials). Compared to CABG, PCI was associated with higher mortality [incidence rate ratio (IRR) 1.32, 95% confidence interval (CI) 1.13-1.53], cardiac death (IRR 1.65, 95% CI 1.18-2.33), MI (IRR 2.18, 95% CI 1.70-2.80) and RR (IRR 3.75, 95% CI 2.89-4.85). Compared to CABG, MT was associated with higher mortality (IRR 1.52, 95% CI 1.26-1.84), cardiac death (IRR 3.83, 95% CI 2.12-6.91), MI (IRR 3.22, 95% CI 1.52-6.79) and RR (IRR 3.37, 95% CI 1.67-6.79). Compared to MT, PCI was associated with lower cardiac death (IRR 0.43, 95% CI 0.24-0.78). CABG ranked as the best revascularization strategy for mortality, cardiac death, MI and RR; MT ranked as the strategy associated with the lowest incidence of stroke. Left ventricular ejection fraction, year of study, use of drug-eluting stents did not affect relative treatment effects. CONCLUSIONS CABG appears to be the best therapy for iLVSD, although mainly based on observational data. Definitive randomized controlled trials comparing CABG and PCI in iLVSD are required.

Abstract
BACKGROUND AND AIM To evaluate the publication rate of articles related to cardiac surgery in the four main cardiovascular journals over the last 5 years. METHODS A bibliometric review of all full-length articles published between January 2014 and March 2020 in the top four cardiovascular journals (Circulation, European Heart Journal (EHJ), Journal of the American College of Cardiology (JACC), and JAMA Cardiology) was conducted. For each eligible article in the four journals, the journal of publication, study design, area of interest, country of origin, and type of intervention tested (for cardiac surgery and interventional cardiology studies) were extracted. The affiliations of all editorial board members were identified from journal websites or from online searches and recorded as from cardiac surgery, cardiology, or another discipline. Correlations between variables were evaluated. RESULTS A total of 4835 articles were reviewed. Cardiac surgery studies amounted to 6.2% (104) of total research publications in JACC, 4.4% (74) in Circulation, 3.6% (13) in JAMA Cardiology, and 2.0% (22) in EHJ (P < .001). The percentage of cardiac surgery publications was significantly less than interventional cardiology publications (P < .001). CONCLUSIONS Cardiac surgery studies represent only a small minority of the articles published in the top cardiovascular journals over the last 5 years, with significant differences between individual journals. Cardiac surgery studies were more often observational and this may constitute one important reason for their under-representation.

Abstract
OBJECTIVE Adverse donor reactions in normal healthy blood donors is not unusual. However, these unpleasant effects have a negative impact on donor retention. Adverse event due to blood donation is multifactorial in origin. Therefore, the objective of this study was to determine the frequency and type of adverse donor reactions during or after blood donation. More importantly, this study also aimed at analyzing important risk predictors of adverse donor reaction. MATERIAL AND METHODS This was a retrospective study conducted from May 2017 to April 2019 in the department of Transfusion Medicine at a tertiary care center in eastern India. Data were stored in Microsoft excel 2016 by using a standardized format as per ISBT criteria and analyzed with software "R, version 3.5.3" to find out the various independent precipitating factor. RESULTS Overall, 107 donors (0.98%) experienced adverse events with 10,814 whole blood donations. The first time, females, younger age donors (18-30 years), and donors with a mean arterial blood pressure of less than 90mm of Hg were the most important independent risk factors predicting the possibility of adverse donor reaction. Donors' weight, hemoglobin, and the type of donation had not affected the frequency of adverse events. CONCLUSION Analysis of adverse donor reactions helps in selecting the blood donors who are at risk of donor reactions. Our study highlights the importance of proper predonation screening especially in terms of assessment of mean blood pressure, along with identification of first time and female blood donors in order to reduce untoward donor reaction.

Abstract
Background Current cardiac surgery guidelines give Class I and II recommendations to valve‐sparing root replacement over the Bentall procedure, mitral valve (MV) repair over replacement, and multiple arterial grafting with bilateral internal thoracic artery based on observational evidence. We evaluated the robustness of the observational studies supporting these recommendations using the E value, an index of unmeasured confounding. Methods and Results Observational studies cited in the guidelines and in the 3 largest meta‐analyses comparing the procedures were evaluated for statistically significant effect measures. Two E values were calculated: 1 for the effect‐size estimate and 1 for the lower limit of the 95% CI. Thirty‐one observational studies were identified, and E values were computed for 75 effect estimates. The observed effect estimates for improved clinical outcomes with valve‐sparing root replacement versus the Bentall procedure, MV repair versus replacement, and grafting with bilateral internal thoracic artery versus single internal thoracic artery could be explained by an unmeasured confounder that was associated with both the treatment and outcome by a risk ratio of more than 16.77, 4.32, and 3.14, respectively. For MV repair versus replacement and grafting with bilateral internal thoracic artery versus single internal thoracic artery, the average E values were lower than the effect sizes of the other measured confounders in 33.3% and 60.9% of the studies, respectively. For valve‐sparing root replacement versus the Bentall procedure, no study reported effect sizes for associations of other covariates with outcomes. Conclusions The E values for observational evidence supporting the use of valve‐sparing root replacement, MV repair, and grafting with bilateral internal thoracic artery over the Bentall procedure, MV replacement, and grafting with single internal thoracic artery are relatively low. This suggests that small‐to‐moderate unmeasured confounding could explain most of the observed associations for these procedures.

Abstract
Coronary artery bypass grafting (CABG) is one of the most commonly performed cardiac procedures in the United States (US) and Europe. In the US, perioperative morbidity and mortality related to CABG are below 5%. One of the most significant complications following CABG, however, is perioperative myocardial infarction (PMI). Cardiac biomarkers, intra- and post-operative echocardiography, and electrocardiography are routinely used to monitor for evidence of PMI. In this review, we seek to summarize how each of these modalities is used in the clinical setting to differentiate PMI from expected procedure-related changes, and how these findings impact patients' outcomes. We conclude that while no perfect diagnostic test for the detection of clinically meaningful PMI exists, using a combination of existing modalities with knowledge of expected post-procedure changes allows for early and reliable detection. Future development is needed to create more sensitive and specific modalities for the detection of PMI in patients undergoing CABG.

Effect of Concomitant Coronary Artery Bypass Grafting on Outcomes of Ascending Aorta Replacement. Ann Thorac Surg 2020; 110:2041-2046. [PMID: 32343949 DOI: 10.1016/j.athoracsur.2020.03.070] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2019] [Revised: 03/04/2020] [Accepted: 03/23/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND Ascending aorta replacement can be performed safely in high-volume centers. What remains unknown is whether concomitant coronary revascularization with bypass grafting affects postoperative outcomes. METHODS This study retrospectively reviewed a prospectively maintained institutional database for patients who underwent ascending aorta replacement (AAR) during the period from 1997 to 2018. Patients were stratified into AAR alone (AAR) vs AAR and coronary artery bypass graft (AAR with CABG), further categorized as 1 or more than 1 CABG. Aortic dissection and root replacement cases were excluded. The primary end point consisted of major adverse events (MAE), including operative mortality, perioperative myocardial infarction, stroke, need for tracheostomy, and need for dialysis. Secondary end points were operative mortality, each MAE component, and late survival. RESULTS A total of 951 patients were included in the analysis; 725 (76.2%) underwent isolated AAR, and 226 (23.8%) underwent AAR with CABG. Operative mortality was similar across the 2 groups (1.8% for AAR with CABG and 0.8% for AAR; P = .40). The unadjusted incidence of MAE was higher in the AAR with CABG group (5.8% vs 1.9%; P = .005).). On multivariable analysis, the performance of 1 CABG (odds ratio [OR], 1.90; 95% confidence interval [CI], 0.67 to 5.33; P = .23) and more than 1 CABG (OR, 2.65; 95% CI, 0.93 to 7.53; P = .07) was not associated with higher rates of MAE. Preoperative pulmonary dysfunction (OR, 2.51; 95% CI, 1.07 to 5.85; P = .03) was the only independent predictor of MAE. CONCLUSIONS In patients undergoing concomitant CABG with AAR, the performance of concomitant CABG is not associated with an increased risk of MAE.

Abstract
Introduction The complexities and risks inherent to the field of surgery and surgical interventions present unique challenges to the design and analysis of surgical randomized controlled trials (RCT). Prior studies have investigated the practical and methodologic challenges posed by surgical RCTs. To date, however, a comprehensive analysis of the contemporary literature across multiple surgical subspecialties does not exist. In this descriptive analysis, we set out to characterize surgical RCTs over the past 10 years across six major surgical specialties. Methods and analysis A literature search by a medical librarian will be performed to identify all surgical randomized clinical trials published between January 2009 and December 2019 in the two journals with the highest impact factor for six surgical specialties as well as two large general medicine journals. Two reviewers will independently screen the citations retrieved from the literature search and extract data according to a previously described protocol via a pre-defined data collection form. Categorical variables will be reported as counts and percentages. Following assessment of normality, continuous variables will be reported as mean (standard deviation) or median (inter-quartile range). Based on normality of data, independent t-test or the Mann-Whitney U test will be used to compare continuous variables and chi-square and Fisher's exact tests to compare categorical variables. Comparisons across multiple sets will be performed using ANOVA or Kruskak-Wallis tests. Two-sided significance testing will be used and a p-value <0.05 will be considered significant without adjustment for multiple testing. All analyses will be performed using SPSS version 24 and R within RStudio. PROSPERO (ID number: 162797). Ethics and dissemination There are no ethical concerns directly pertinent to this systematic review. The retrieved data will be made available upon request. The study will be written in English and submitted for publication in a peer-reviewed journal.

Comparison of the effects of hemodialysis and hemodiafiltration on left ventricular hypertrophy in end-stage renal disease patients: A systematic review and meta-analysis. Semin Dial 2020; 33:120-126. [PMID: 32159258 DOI: 10.1111/sdi.12864] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Revised: 02/17/2020] [Accepted: 02/20/2020] [Indexed: 12/15/2022]
Abstract
Whether hemodiafiltration (HDF) is better than conventional hemodialysis (HD) in improving left ventricular hypertrophy (LVH), defined as reduction of the left ventricular mass index (LVMi) and increasing the ejection fraction (EF), is unclear. A systematic literature search was performed. Primary outcome was the mean difference between pre- and post-procedural LVMi. Secondary outcome was the mean difference in EF. Seven studies with a total of 845 patients were included. The pooled mean difference between pre-and post-procedural LVMi was -8.0 g/m2 (95% confidence interval [CI] -13.1, -2.8). On subgroup analysis, the mean differences between pre- and post-procedural LVMi for HD and HDF were -6.7 g/m2 (95% CI -14.5, 1.1) and -9.3 g/m2 (95% CI -16.3, -2.3), respectively (P for subgroups = .62). Pooled mean difference between pre- and post-procedural EF was 2.4% (95% CI -1.8, 6.5). On subgroup analysis, the mean differences between pre- and post-procedural EF for HD and HDF were 3.6% (95% CI -2.7, 9.8) and 2.0% (95% CI 2.9, 6.8), respectively (P for subgroups = .68). On meta-regression, age (Beta -0.35 ± 0.05, P < .001) and longer dialysis duration (Beta -0.12 ± 0.02, P < .001) were associated with lower mean difference between pre-and post-procedural EF. No significant effects on changes in LVMi and EF were observed with HDF compared with conventional HD.

Abstract
AIM To identify policies on the consumption of hot drinks by patients and visitors on all perinatal and postnatal wards in the United Kingdom, and to seek the opinions of members of the wider burns MDT as to whether standardised patient education or regulation of hot drinks around newborn babies is required. METHODS All maternity units with postnatal wards across the United Kingdom were surveyed to establish availability of hot drinks on site and whether these were permitted on postnatal wards around infants. An online questionnaire was distributed to members of the British Burn Association to ascertain opinions on hot drinks policies. RESULTS Hot takeaway drinks were permitted around newborn infants in 194 of surveyed postnatal wards and were only banned by two units. The online survey received 49 responses from different members of the British Burn Association. Thirty responders (61%) supported a takeaway hot drink ban, while those against the policy would alternatively encourage patient education, dedicated drinking areas and introduction of safety measures. CONCLUSIONS Almost every postnatal unit in the UK has access to hot drink retailers on site allowing parents and visitors to bring them into close contact with babies. With varying local regulations, this poses potentially serious consequences during feeding or carrying. We propose a standardised antenatal education be made available, together with standardised designated areas on wards for parents and visitors to consume hot drinks away from infants.

Abstract
BACKGROUND When transcatheter aortic valve replacement (TAVR) was first approved by the Food and Drug Administration in October 2011, it was an innovative treatment with limited accessibility. However, over the past few years, TAVR has become standard of care in patients with aortic stenosis. The effect of socioeconomic status (SES) on this transition of use of TAVR is unknown. METHOD Using the New York state department Statewide Planning and Research Cooperative System database, we compared baseline patient characteristics and facilities in low-income areas and high-income areas. Trends in residential SES of patients undergoing TAVR were examined over time and assessed with a Poisson regression and Cochran Armitage trend tests. RESULT From October 2011 and 2012 to December 2016, we found that the numbers of TAVR procedures performed among patients from both low (187-1150 in 2016, P < .001) and high (227-1160, P < .001) income areas increased over time. The proportion of TAVR procedures performed in patients from low-income areas increased over time, while those in high-income areas decreased (from 45.2% in 2011 and 2012 to 49.8% in 2016 for low-income and from 54.8%-50.2% for high-income, P = .009). CONCLUSION In the case of TAVR in New York State, when the innovative treatment was introduced in the clinical practice, there were initial SES-based disparities in access to the procedure. However, these disparities resolved over time, probably due to the broader diffusion of the technique.

Abstract
Animal models have provided invaluable information in the pursuit of medical knowledge and alleviation of human suffering. The foundations of our basic understanding of disease pathophysiology and human anatomy can largely be attributed to preclinical investigations using various animal models. Recently, however, the scientific community, citing concerns about animal welfare as well as the validity and applicability of outcomes, has called the use of animals in research into question. In this review, we seek to summarize the current state of the use of animal models in research.

Abstract
Recent global concern regarding the impact of plastic waste on the environment has resulted in efforts to utilise reusable drink containers. Research is lacking regarding temperature dissociation of drinks in reusable thermoplastic cups. This study aimed to compare the cooling time of two common hot drinks sold at a UK retailer, in the three vessels they are sold; ceramic, disposable paper (with and without lid) and reusable thermoplastic cups (with and without lid). All temperatures were collated from 250 ml volumes of black Americano coffee or café latte in the three different containers. The cooling time was measured every sixty seconds using a standardised digital thermocouple thermometer until a threshold liquid temperature of 43 °C was reached. All experiments were performed in triplicate and temperatures converted to a dimensionless logarithmic scale prior to statistical analysis. Cooling time was significantly slower for lidded cups irrespective of material. Unlidded thermoplastic cups significantly slowed cooling times for both black Americano coffee and café latte compared to ceramic and unlidded disposable paper cups. The growing trend in reusable cups does not in itself pose an increased risk of scald injury. However, we consider that the potentially increased ambulatory behaviour associated with using a lidded rather than unlidded cup may increase scald risk. We propose that further consumer guidance should be disseminated regarding the use of any lidded takeaway container to prevent scalds in both adults and children.

Abstract
This randomized controlled trial was designed to evaluate whether the combination of low dose oral midazolam (0.25 mg/kg) and low dose oral ketamine (3 mg/kg) provides better premedication than oral midazolam (0.5 mg/kg) or oral ketamine (6 mg/kg). Seventy-eight children of ASA physical status I or II scheduled for elective ophthalmic surgery were randomly divided into three groups and given premedication in the holding area 30 minutes before surgery. Two subjects from each group vomited the medication and were excluded, leaving 72 subjects for further analysis. The onset of sedation was earlier in the combination group than the other two groups. At 10 minutes after premedication 12.5% in the combination group had an acceptable sedation score compared with none in the other two groups. After 20 minutes 54% in the combination group had an acceptable sedation score, 21% in the midazolam group and 16% in the ketamine group (P<0.05). There were no significant differences in the parental separation score, response to induction and emergence score. The mean time for best parental separation score was significantly less in the combination group (19±8 min) than either the midazolam (28±7) or ketamine (29±7 min) groups (P<0.05). Recovery was earlier in the combination group, as the time required to reach a modified Aldrete score of 10 was significantly less in the combination group (22±5 min) than in the oral midazolam (36±11 min) or ketamine (38±8 min) groups. The incidence of excessive salivation was significantly higher in the ketamine alone group (P<0.05). In conclusion, the combination of oral ketamine (3 mg/kg) and midazolam (0.25 mg/kg) has minimal side effects and gives a faster onset and more rapid recovery than ketamine 6 mg/kg or midazolam 0.5 mg/kg for premedication in children.

Abstract
Objective To test the psychometric properties of the Oral Health Literacy Adult Questionnaire (OHL-AQ) in English. The OHL-AQ was designed to test functional oral health literacy in general populations and was initially validated in Iran. Methods The instrument was administered to 405 adult subjects (mean age 45 (SD 16) years and 67% female) attending the 2014 Minnesota State Fair. The OHL-AQ is composed of 17 items measuring four conceptual dimensions: reading comprehension, numeracy, listening, and decision-making. Participants selected the best answer for written or verbally administered items and entered answers on an electronic tablet. Item responses for each individual were combined into a summary score (range 0-17) with higher scores indicating better oral health literacy. Score dimensionality, reliability, and validity were investigated. Results For dimensionality, both exploratory factor analysis and a parallel analysis yielded evidence for scale unidimensionality. Reliability was sufficient indicated by a Cronbach's alpha ⟩0.74. Validity of scores was supported by "small" and "medium" effect sizes for construct validity. "Small" effect sizes were observed for global oral health self-report, OHIP-5 scores, treatment urgency, and having a regular dentist. "Medium" effect sizes were seen for presence of dentures, number of natural teeth present, and educational level. Conclusions Dimensionality, reliability and validity of the English version of the OHL-AQ in a general adult English-speaking population is supported, providing sufficient psychometric properties in an important target population of the instrument.

Abstract
OBJECTIVE Chronic symptomatic sinus node dysfunction (SND), the most common bradyarrhythmia, can be effectively managed by permanent cardiac pacing. Yet the care pathway and barriers to adoption of pacing therapy are not well understood - particularly in low volume implanting countries. The IMPROVE Brady study is a quality improvement initiative being conducted at centers in South Asia, Latin America, and Russia. We assessed the rates of SND diagnosis and pacemaker treatment for SND in the South Asia cohort. METHODS The prospective study enrolled patients with heart rate of ≤50 beats per minute presenting with symptoms including syncope, dizziness, and/or dyspnea from ten centers in India and Bangladesh. Patients were followed to identify the proportion diagnosed with SND and subsequently treated with pacemaker therapy. RESULTS A total of 508 patients meeting criteria were enrolled and followed on average for 8.3±8.0months. Patients were on average 58 years of age, 77% were male, and 91% had completed at least primary education. An SND diagnosis was made in 368 (72%) of patients, with the majority (80%) of diagnoses occurring within 1 month of enrollment. Of the patients with an SND diagnosis, 63 (17%) were treated with a pacemaker. Reasons for not receiving treatment were: subject refusal or deferred decision (45%), unaffordability (34%), physician determined - not-indicated (20%), and other (1%). Older age, female gender, history of hypertension, lower resting heart rate, and syncopal or pre-syncopal symptoms were associated with a higher probability of implant. CONCLUSIONS In a care pathway assessment for the diagnosis and treatment of symptomatic SND in South Asia only 1 in 6 patients received pacemaker indicated therapy, largely due to patient refusal and physician decision. Phase II of the study will be aimed to improve this treatment rate.

Abstract
Background: Ample information is available on extreme heat associated mortality for few Indian cities, but scant literature is available on effect of temperature on spatial variability of all-cause mortality for coastal cities. Objective: To assess the effect of daily maximum temperature, relative humidity and heat index on spatial variability of all-cause mortality for summer months (March to May) from 2014 to 2015 for the urban population of Surat (coastal) city. Materials and Methods: Retrospective analysis of the all-cause mortality data with temperature and humidity was performed on a total of 9,237 deaths for 184 summer days (2014-2015). Climatic and all-cause mortality data were obtained through Tutiempo website and Surat Municipal Corporation respectively. Bivariate analysis performed through SPSS. Observations: Mean daily mortality was estimated at 50.2 ± 8.5 for the study period with a rise of 20% all-cause mortality at temperature ≥ 40°C and rise of 10% deaths per day during extreme danger level (HI: > 54°C) days. Spatial (Zone wise) analysis revealed rise of 61% all-cause mortality for Southeast and 30% for East zones at temperature ≥ 40°C. Conclusions: All-cause mortality increased on high summer temperature days. Presence of spatial variation in all-cause mortality provided the evidence for high risk zones. Findings may be helpful in designing the interventions at micro level.

Abstract
Aim A national atrial fibrillation (AF) registry was conducted under the aegis of the Indian Heart Rhythm Society (IHRS), to capture epidemiological data-type of AF, clinical presentation and comorbidities, current treatment practices, and 1-year follow-up outcomes. Methods A total of 1537 patients were enrolled from 24 sites in India in the IHRS-AF registry from July 2011 to August 2012. Their baseline characteristics and follow-up data were recorded in case report forms and subsequently analyzed. Results The average age of Indian AF patients was 54.7 years. There was a marginal female preponderance – 51.5% females and 48.5% males. At baseline, 20.4% had paroxysmal AF; 33% had persistent AF; 35.1% had permanent AF and 11% had first AF episode. At one-year follow-up, 45.6% patients had permanent AF. Rheumatic valvular heart disease (RHD) was present in 47.6% of patients. Hypertension, heart failure, coronary artery disease, and diabetes were seen in 31.4%, 18.7%, 16.2%, and 16.1%, respectively. Rate control was the strategy used in 75.2% patients, digoxin and beta-blockers being the most frequently prescribed rate-control drugs. Oral anticoagulation (OAC) drugs were used in 70% of patients. The annual mortality was 6.5%, hospitalization 8%, and incidence of stroke 1%. Conclusions In India, AF patients are younger and RHD is still the most frequent etiology. Almost two-third of the patients have persistent/permanent AF. At one-year follow-up, there is a significant mortality and morbidity in AF patients in India.

Underutilization of Timely Kidney Transplants in Those With Living Donors. Am J Transplant 2016; 16:1007-14. [PMID: 26845755 DOI: 10.1111/ajt.13592] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2015] [Revised: 10/06/2015] [Accepted: 10/22/2015] [Indexed: 01/25/2023]
Abstract
Preemptive kidney transplant (PKTx) and kidney transplant (KTx) within 1 year of dialysis initiation have been associated with superior outcomes. Wait times should be minimal for transplants with living donors; however, there is lack of literature studying utilization of timely KTx in this population. We designed this retrospective study using data from United Network for Organ Sharing Standard Transplant Analysis and Research files from 2000 to 2012 to assess the trends in utilization of PKTx and Early KTx (combination of PKTx or transplant within 1 year of dialysis initiation) in recipients of living donor KTx. Only 32.6% transplants were PKTx, and 61.9% were Early KTx. A significant improvement in proportion of PKTx was seen from 27.5% in 2000 to 35.4% in 2006, with no change since. Similarly, the proportion of Early KTx increased from 61.4% in 2000 to 63.6% in 2006, with no increase since. Similar results were seen after adjusted analysis and were independent of living donor type. Although there was some improvement in utilization of timely transplants in the early part of the last decade, there has been no improvement since. Considering the benefits of timely kidney transplant, it is important to understand the reasons behind the same and to improve utilization.

When the living and the deceased cannot agree on organ donation: a survey of US organ procurement organizations (OPOs). Am J Transplant 2014; 14:172-7.

Abstract
The legal concept of first person authorization (FPA) is based on the principle that a decision by a person with decision-making capacity should be respected even after he or she dies. Although the transplant community largely supports this concept, its implementation has not been universal. We conducted a web-based survey of all 58 Organ Procurement Organization (OPO)executive directors in the United States to assess OPOs' procurement policies and practices in the context of family objections. All 58 respondents(100%) responded to our survey. All OPOs except one have an online donor registration website. Most OPOs(89%) (51 of 57 respondents) estimated that the frequency of family objecting to organ donation in cases of registered donors was <10%. No OPOs reported the frequency to be higher than 25%. Only 50% (27 of 54) of the OPOs have a written policy on handling family objections. Approximately 80% of the OPOs reported honoring FPA. However, in the past 5 years, 20 OPOs (35%) have not yet participated in organ procurement from a registered deceased donor over family objection. Further research to identify the barriers and possible solutions to implementing FPA is warranted.
