1-1 µM) over 10 minutes before ischemia. In a second series of experiments, hearts were treated with 0.3 µM sildenafil or 1 µM milrinone as the "protective" concentrations. A higher concentration of respective drugs did not further reduce infarct size. In addition, a combination of "protective" and "nonprotective" concentrations of sildenafil and milrinone was applied. Sildenafil and milrinone in lower concentrations led to significant infarct size reduction, whereas combining both substances in cardioprotective concentrations did not enhance this effect. Sildenafil in a concentration of 0.3 µM induces myocardial protection. Furthermore, treatment with sildenafil and milrinone in lower concentrations had an equally strong cardioprotective effect regarding infarct size reduction compared with the administration of "protective" concentrations.
The rapid growth of opioid abuse and the related mortality across the United States has spurred the development of predictive models for the allocation of public health resources. These models should characterize heterogeneous growth across states using a drug epidemic framework that enables assessments of epidemic onset, rates of growth, and limited capacities for epidemic growth.
We used opioid overdose mortality data for 146 North and South Carolina counties from 2001 through 2014 to compare the retrodictive and predictive performance of a logistic growth model that parameterizes onsets, growth, and carrying capacity within a traditional Bayesian Poisson space-time model.
In fitting the models to past data, the performance of the logistic growth model was superior to the standard Bayesian Poisson space-time model (deviance information criterion 8,088 vs. 8,256), with reduced spatial and independent errors. Predictively, the logistic model more accurately estimated fatality rates 1, 2, and 3 years in the future (root mean squared error medians were lower for 95.7% of counties from 2012 to 2014). Capacity limits were higher in counties with greater population size, percent population age 45-64, and percent white population. Epidemic onset was associated with greater same-year and past-year incidence of overdose hospitalizations.
Growth in annual rates of opioid fatalities was capacity limited, heterogeneous across counties, and spatially correlated, requiring spatial epidemic models for the accurate and reliable prediction of future outcomes related to opioid abuse. Indicators of risk are identifiable and can be used to predict future mortality outcomes.

As the numbers of senior golfers increase, many will consider a hip or knee joint replacement (JR) over their lifetime. The relationship of JR to the rate of return and validated level of play has not been well defined.
A regional golf association's membership was mailed a questionnaire regarding their JR. Members with valid Golf Handicap Information Network numbers and with at least five pre- and post-JR scores were included. Prospectively collected rounds of play and handicap differentials were used for the analysis.
Two hundred fifty-one members reported having a JR, with 120 qualifying for the analysis. The sites of JR include 50 hips (41.7%) and 70 kness (58.3%). Plays per month after the first JR increased from 5.2 to 5.6 (P = 0.017). Handicap differentials increased from an average of 15.8 to 17.3 (P < 0.0001). Average return to play was 62 days. Twenty-eight players who had a second JR saw an increase in plays per month from 4.2 to 6.3 (P = 0.0074) and an increase in handicap differentials from 19.3 to 20.2 (P = 0.0036).
After the initial JR, amateur golfers will likely play more frequently; however, the level of play will typically decrease slightly. The same effects are seen after a subsequent JR.

Recent research points to considerable rates of preventable perioperative patient harm and anaesthesiologists' concerns about eroding patient safety. Anaesthesia has always been at the forefront of patient safety improvement initiatives. However, factual local safety improvement requires local measurement, which may be afflicted by barriers to data collection and improvement activities. click here Because many of these barriers are related to mandatory reporting, the focus of this review is on measurement methods that can be used by practicing anaesthesiologists as self-improvement tools, even independently from mandatory reporting, and using basic techniques widely available in most institutions.
Four mutually complementary measurement approaches may be suited for local patient safety learning incident and rate-based measurements, staff surveys and patient surveys. Reportedly, individual methods have helped to tailor problem solutions and to reduce patient harm, morbidity, and mortality.
Considering the potential for perioperative patient safety measurements to improve patient outcomes, the absence of a generally accepted measurement standard and manifold barriers to reporting, a pragmatic approach to locally measuring patient safety appears advisable.

General anesthesia is a popular choice for ambulatory surgery. Spinal anesthesia is often avoided because of perceived delays due to time required to administer it and prolonged onset, as well as concerns of delayed offset, which may delay recovery and discharge home. However, the reports of improved outcomes in hospitalized patients undergoing total joint arthroplasty have renewed the interest in spinal anesthesia. This review article critically assesses the role of spinal anesthesia in comparison with fast-track general anesthesia for the outpatient setting.
The purported benefits of spinal anesthesia include avoidance of airway manipulation and the adverse effects of drugs used to provide general anesthesia, improved postoperative pain, and reduced postoperative opioid requirements. Improved postoperative outcomes after spinal anesthesia in hospitalized patients may not apply to the outpatient population that tends to be relatively healthier. Also, it is unclear if spinal anesthesia is superior to fast-track general anesthesia techniques, which includes avoidance of benzodiazepine premedication, avoidance of deep anesthesia, use of an opioid-sparing approach, and minimization of neuromuscular blocking agents with appropriate reversal of residual paralysis.
