Transcatheter Aortic Valve Implantation With or Without Preimplantation Balloon Aortic Valvuloplasty: A Systematic Review and Meta-Analysis

Journal of the American Heart Association, Jan 13, 2016

Preimplantation balloon aortic valvuloplasty (BAV) is considered a routine procedure during trans... more Preimplantation balloon aortic valvuloplasty (BAV) is considered a routine procedure during transcatheter aortic valve implantation (TAVI) to facilitate prosthesis implantation and expansion; however, it has been speculated that fewer embolic events and/or less hemodynamic instability may occur if TAVI is performed without preimplantation BAV. The aim of this study was to systematically review the clinical outcomes associated with TAVI undertaken without preimplantation BAV. We conducted a search of Medline and Embase to identify studies that evaluated patients who underwent TAVI with or without preimplantation BAV for predilation. Pooled analysis and random-effects meta-analyses were used to estimate the rate and risk of adverse outcomes. Sixteen studies involving 1395 patients (674 with and 721 without preimplantation BAV) fulfilled the inclusion criteria. Crude device success was achieved in 94% (1311 of 1395), and 30-day all-cause mortality occurred in 6% (72 of 1282) of patient...

Meta-Analysis of the Prognostic Impact of Anemia in Patients Undergoing Percutaneous Coronary Intervention

This review aims to examine the relation between baseline anemia and mortality, major adverse cardiovascular events (MACE), and major bleeding in patients undergoing PCI. We searched MEDLINE and EMBASE for studies that evaluated mortality and adverse outcomes in anemic and nonanemic patients who underwent PCI. Data were collected on study design, participant characteristics, definition of anemia, follow-up, and adverse outcomes. Random effects meta-analysis of risk ratios was performed using inverse variance method. A total of 44 studies were included in the review with 230,795 participants. The prevalence of baseline anemia was 26,514 of 170,914 (16%). There was an elevated risk of mortality and MACE with anemia compared with no anemia-pooled risk ratio (RR) 2.39 (2.02 to 2.83), p <0.001 and RR 1.51 (1.34 to 1.71), p <0.001...

Revisiting Pneumatic Nail Gun Trigger Recommendations

Professional safety, 2015

Use of a pneumatic nail gun with a sequential actuation trigger (SAT) significantly diminishes th... more Use of a pneumatic nail gun with a sequential actuation trigger (SAT) significantly diminishes the risk for acute traumatic injury compared to use of a contact actuation trigger (CAT) nail gun. A theoretically-based increased risk of work-related musculoskeletal disorders from use of a SAT nail gun, relative to CAT, appears unlikely and remains unproven. Based on current knowledge, the use of CAT nail guns cannot be justified as a safe alternative to SAT nail guns. This letter provides a perspective of ergonomists and occupational safety researchers recommending the use of the sequential actuation trigger for all nail gun tasks in the construction industry.

The aim of this study is to provide an overview of site-specific major bleeding events in contemporary PCI and study their impact on mortality and major adverse cardiovascular event outcomes. We conducted a meta-analysis of PCI studies that evaluated site-specific periprocedural bleeding complications and their impact on major adverse cardiovascular events and mortality outcomes. A systematic search of MEDLINE and Embase was conducted to identify relevant studies and random effects meta-analysis was used to estimate the risk of adverse outcomes with site-specific bleeding complications. Twenty-five relevant studies including 2 400 645 patients that underwent PCI were identified. Both non-access site (risk ratio [RR], 4.06; 95% confidence interval [CI], 3.21-5.14) and access site (RR, 1.71; 95% CI, 1.37-2.13) related bleeding complications w...

Musculoskeletal concerns do not justify failure to use safer sequential trigger to prevent acute nail gun injuries

American journal of industrial medicine, 2015

Acute nail gun injuries can be controlled significantly by using tools with sequential triggers a... more Acute nail gun injuries can be controlled significantly by using tools with sequential triggers and training. Concern has been raised that sequential triggers, which require that the nose piece of the gun be depressed prior to pulling the trigger, could increase risk of musculoskeletal problems. We conducted active injury surveillance among union carpenter apprentices to monitor acute injuries and musculoskeletal disorders between 2010 and 2013. Acute injury risk was 70% higher with contact trip rather than sequential triggers. Musculoskeletal risk was comparable (contact trip 0.09/10,000 hr (95% CI, 0.02-0.26); sequential 0.08/ 10,000 hr (95% CI 0.02-0.23)). Concern about excess risk of musculoskeletal problems from nail guns with sequential triggers is unwarranted. Both actuation systems carry comparable musculoskeletal risk which is far less than the risk of acute injury; there is clearly no justification for failure to prevent acute injuries through use of the safer sequential t...

Previous studies have reported conflicting data on radial access site adoption between different age groups, with age an independent predictor of failure of procedures undertaken through the radial approach. Age and access site related outcomes (based on transradial (TRA) and transfemoral (TFA) access) were studied in 469,983 PCI procedures undertaken in the UK from 2006 to 2012 in the age groups; &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;60, 60-&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;70, 70-&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;80, and ≥80 in the British Cardiovascular Intervention Society database.

Transradial access (TRA) has been associated with improved patient outcomes in selected populations in randomized trials. It is unclear whether these outcomes are achievable in clinical practice. Using the BCIS (British Cardiovascular Intervention Society) database, we investigated outcomes for percutaneous coronary intervention procedures undertaken between 2007 and 2012 according to access site practice. Patients were categorized as stable, non-ST-segment elevation acute coronary syndrome (NSTEACS) and ST-elevation acute coronary syndrome (STEACS). The impact of access site on 30-day mortality, major adverse cardiac events, bleeding, and arterial access site complications was studied. Data from 210,260 TRA and 229,687 transfemoral access procedures were analyzed. Following multivariate analysis, TRA was independently associated ...

Subsidization of the Biofuel Industry: Security vs. Clean Air?

Certain crops can be used as inputs for the production of alternative fuels. In addition to these two benefits, the development of biofuel industry has other secondary advantages including rural development. As the current price of biofuel is considerably greater than the price of fossil fuel alternatives, the governments around the world are heavily subsidizing the development of this industry. This paper focuses on the growth of biofuel industry in Canada and US. We develop a theoretical model to examine whether or not the same governmental policy (subsidization) yields different results i.e. a different level of optimal subsidies under different current objectives. We consider that subsidizing the development of the biofuel industry in the present is equivalent to buying an option on its use for future goals -energy security or reduced GHG emissions-so our research uses option value theory to assess these alternatives. The theoretical model yields an optimal subsidy option function for each of the two countries. Furthermore, under the scenario of obtaining different optimal levels of subsidies in the two countries, trade disputes can arise. A numerical simulation method is proposed to quantify the optimal level of subsidy option for each country.
