One hundred one patients underwent the Abbott iSTAT analysis, 139 patients underwent Nova StatSensor analysis, and 53 had both. ![]() One hundred eighty-six patients were included in the study. eGFR values were stratified as high risk (eGFR < 30), moderate risk (eGFR 30-59) and low risk (eGFR ≥ 60). Renal function was calculated using eGFR via the CKD-EPI result. The two values were analysed and compared. Patients undergoing routine radiological investigations had blood collected and analysed by a POC method and the laboratory method (Beckman AU5800). Two POC devices were evaluated, the Nova StatSensor and Abbott iSTAT. Point of care (POC) devices offer a quick estimation of renal function, potentially improving workflows in radiology departments. One of the biggest risk factors for developing PC-AKI is the presence of pre-existing renal dysfunction, making it important to measure the renal function prior to contrast administration. There exists a small risk of post-contrast acute kidney injury in patients receiving IV contrast.

Instead, The Cuphead Show! is a collection of standalone cartoons that have fun splashing around in the tropes of the era its animation was inspired by. ![]() The show deliberately harkens back to a time where entertainment wouldn’t hesitate to scare kids. While there’s a loose nod to the game’s plot – in which Cuphead and Mugman lose their souls by gambling with the devil, who in turn forces them to chase down his debtors – this is by no means a dramatisation. The show sees Cuphead (a headstrong and cocky sentient cup) and his brother Mugman (in effect, a differently coloured Cuphead created solely to allow a two-player mode on the game, here beefed up into a cowardly Luigi type) as they blunder through a succession of wacky misadventures. Because The Cuphead Show! feels like Cuphead reaching its most perfect form. It might sound complicated – a cartoon based on a game based on a different cartoon – but go along with it. ![]() Which brings us to The Cuphead Show! (Netflix), in which the Cuphead characters are given their own series of 15-minute cartoons. The game might have caused you to rip out your hair in frustration, but the characters were too charming to be dismissed. You might not be able to get past the level where you have to steal the soul from a giant onion (long story), but you could still buy Cuphead dolls and Cuphead books, and you could visit YouTube and watch a seemingly limitless number of users create no end of Cuphead songs, cartoons and comparison videos. The characters were so engaging, and the aesthetic so beautiful, that a small cottage industry sprang up around it. It seemed like such a wasted opportunity.Īnd yet, despite this, the kernel of Cuphead remained irresistible. One early reviewer (who plays games for a living, remember) noted that he had died 188 times during the game. It might have looked and sounded beautiful, but it was also cripplingly difficult to play. But then the game came out, and it sort of sucked. ![]() ![]() ![]() X-rays of acetabular fractures are taken from a number of different angles to show the pattern of the fracture and how out of place the bones are (displacement). These studies provide images of dense structures, such as bones. You doctor will also carefully examine the rest of your body to determine if you have received any other injuries. In some cases, nerves may be injured at the same time that the acetabulum is fractured. He or she will also check to see if you can move your ankles and toes and feel sensation on the bottom of your feet. Your doctor will perform a thorough examination of your pelvis, hips, and legs. If there is significant blood loss, it may lead to shock-a life-threatening condition that can result in organ failure. If the fracture is due to high-energy trauma, there may also be injuries to the head, chest, abdomen, or legs. Patients with fractures caused by high-energy trauma will almost always go or be brought to an urgent care center or emergency room for initial treatment because of the severity of their symptoms. How is an acetabular fracture diagnosed? Emergency Stabilization Although these patients do not often have other injuries, they may have complicating medical problems, such as heart disease or diabetes. This is most common in older patients whose bones have become weakened by osteoporosis. When the fracture is caused by high-energy impact, patients often experience extensive bleeding and have other serious injuries that require urgent attention.Īcetabular fractures are sometimes caused by weak or insufficient bone. Depending upon the direction of the force, the head of the femur is sometimes pushed out of the hip socket, an injury called hip dislocation. ![]() This force can be transmitted from the knee (such as hitting the knee against the dashboard in a head-on car collision) or from the side (such as falling off a ladder directly onto the hip). ![]() What causes acetabular fractures?Īn acetabular fracture results when a force drives the head of the femur against the acetabulum. When they do occur, they are usually the result of very high-energy trauma. Open fractures of the acetabulum are rare because the hip joint is well covered with soft tissues. Immediate treatment is required to prevent infection. This type of fracture is particularly serious because, once the skin is broken, infection in both the wound and the bone can occur. If the bone breaks in such a way that bone fragments stick out through the skin or a wound penetrates down to the broken bone, the fracture is called an "open" or compound fracture. The injury to surrounding soft tissues, such as muscle, tendons, nerves, and skin.The injury to the cartilage surfaces of both the acetabulum and the head of the femur.The amount each piece is out of place - In some cases, the broken ends of bones line up well in more severe fractures, there may be a large gap between the broken pieces, or the fragments may overlap each other.The number and size of the fracture fragments.The severity of the injury depends on several factors, including: How is the severity of an acetabular fracture measured? If the joint remains irregular or unstable, ongoing cartilage damage to the surfaces may lead to arthritis. When the acetabulum is fractured, the femoral head may no longer fit firmly into the socket, and the cartilage surface of both bones may be damaged. For example, the bone can break straight across the socket or shatter into many pieces. What is an acetabular fracture?Īcetabular fractures vary. These structures can occasionally be damaged as the result of an injury to the acetabulum. Major nerves, blood vessels, and portions of the bowel, bladder, and the reproductive organs all pass within or close to the pelvis. These ligaments help provide both function and stability to the hip joint, allowing it to move without falling out of the socket. Bands of tissue called ligaments connect one bone to another. The bone surfaces of the ball and socket are covered with articular cartilage-a smooth, slippery substance that protects and cushions the bones and enables them to move easily. The ball is the femoral head, which is the upper end of the femur (thighbone). The socket is formed by the acetabulum, which is part of the pelvis. ![]() The hip is one of the body's largest joints. Treatment for acetabular fractures often involves surgery to restore the normal anatomy of the hip and stabilize the hip joint.

The chance to water your plants isn't the only new feature in Trine 2 though there's also a wealth of new enemies and boss characters who pose more of a threat than the goblins of old. There's the usual problem with fluid technology in that what is meant to be water seems to look and behave more like oil, but it's an issue we can easily overlook given how much it adds to the game. Mechanically, fluid physics are one of the major additions to the game, mostly appearing in the form of waterfalls, which players must redirect to clear obstacles or grow mystical plants that will allow access to new areas. A PlayStation Network and Xbox Live Arcade release is coming soon.Trine 2 PC ReviewMoving the game beyond the constraints of the original Trine are a number of other new features and improvements that have been woven into the sequel - the fabulous new graphics are just the start. Trine 2 is currently available for PC and Mac. Intelligent puzzle designs offer plenty of rewarding play and its breathtaking visuals make it a trophy game for anyone that owns a high-spec PC. While Trine 2 may falter with its enemy encounters, it certainly merits checking out. With healing stations only inches away, losing these fights is nearly impossible, leaving them to feel like filler. These forced battles are among the more tedious parts of the game. There are a few exceptions, such as a stage in which a giant ogre waits at the end with club in-hand. Again, brute force is not an option in many cases. Whatever the difficulty setting, expect to see plenty of large monsters, like fire-breathing snakes and giant spiders, as a number of the game's puzzles involve finding ways to defeat these creatures. I saw a noticeable difference between Easy and Medium difficulties and based on my experience would recommend easy as the way to go for anyone that would rather focus on the game's puzzles. This often felt like a disruption to flow of the game, but players are allowed to reduce the number of enemy encounters by adjusting the difficulty level. Enemies will pop in from both the background and the foreground at random points in-between the puzzling. There's still plenty of more traditional action. These sort of thoughtful puzzles throughout Trine 2 provide its most satisfying moments. After failing to jump over the slimy creature, I figured out that I could use one of Amadeus's powers to create a more appealing spot for mister snail, and lure him into the background, allowing me to proceed. For instance, early on my path was blocked by a giant snail enjoying a shower. Trine 2 stepped up by making me think for a solution as much as pull off some control combo. Once I learned how to do all this, though, the game rewarded me with its more challenging puzzles. It took a little bit to get my fingers moving just right to swing through stages with Zoya's grappling hook, use Amadeus' magic to craft platforms and bring down nearby ledges, and hack through obstacles with Pontius' sword. Finicky keyboard controls made that a more difficult task than it needed to be at times. Progressing often involved learning when to use each hero’s specific skill. Playing single-player, I controlled one hero at a time, with the ability to tag out to a different hero at any time. And once again, they are reunited by the mysterious Trine. A direct sequel to the first game, the trio of playable characters, Amadeus the Wizard, Pontius the Knight, and Zoya the Thief (or "entrepreneur," as she calls herself), return in Trine 2. ![]() When I wasn’t marveling over Trine 2's graphics, I was learning how to use the three heroes. Every world I encountered was filled with rich color, vibrant backgrounds, and meticulously-detailed objects from one edge of the screen to the other. The level of graphical detail is astounding to see, whether in the forests, swamps, or caverns. Trine 2's twelve hour quest was likely lengthened by how often I got distracted by that beauty.

![]() ![]() In other words, a concentration of 1 ppb for a given gas means there is one molecule of that gas in every 1 billion molecules of air. Concentrations of these greenhouse gases are measured in parts per million (ppm), parts per billion (ppb), or parts per trillion (ppt) by volume. As a result of human activities, however, these gases are entering the atmosphere more quickly than they are being removed, and thus their concentrations are increasing.Ĭarbon dioxide, methane, nitrous oxide, and certain manufactured gases called halogenated gases (gases that contain chlorine, fluorine, or bromine) become well mixed throughout the global atmosphere because of their relatively long lifetimes and because of transport by winds. Over time, these gases are removed from the atmosphere by chemical reactions or by emissions sinks, such as the oceans and vegetation, which absorb greenhouse gases from the atmosphere. When greenhouse gases are emitted into the atmosphere, many remain there for long time periods ranging from a decade to many millennia. and Global Greenhouse Gas Emissions indicators). Since the Industrial Revolution began in the 1700s, people have added a substantial amount of greenhouse gases into the atmosphere by burning fossil fuels, cutting down forests, and conducting other activities (see the U.S. Globally, the amount of ozone in the troposphere increased by about 12 percent between 19 (see Figure 5). .These chemicals have been released into the air for many years, but recently, international efforts have reduced emissions and phased out their use. Changes in stratospheric ozone reflect the effect of ozone-depleting substances. All of the decrease happened in the stratosphere, with most of the decrease occurring between 19. Overall, the total amount of ozone in the atmosphere decreased by more than 4 percent between 19 (see Figure 5). ![]() Concentrations of other halogenated gases have continued to rise, however, especially where the gases have emerged as substitutes for ozone-depleting chemicals (see Figure 4, right panel). As a result, concentrations of many major ozone-depleting gases have begun to stabilize or decline (see Figure 4, left panel). ![]() Some of these chemicals have been or are currently being phased out of use because they are ozone-depleting substances, meaning they also cause harm to the Earth’s protective ozone layer. Concentrations of many of the halogenated gases shown in Figure 4 were essentially zero a few decades ago but have increased rapidly as they have been incorporated into industrial products and processes.This increase is primarily due to agriculture. Levels have risen since the 1920s, however, reaching a new high of 334 ppb in 2021 (average of four sites in Figure 3). Over the past 800,000 years, concentrations of nitrous oxide in the atmosphere rarely exceeded 280 ppb.This increase is predominantly due to agriculture and fossil fuel use. The concentration of methane in the atmosphere has more than doubled since preindustrial times, reaching over 1,800 ppb in recent years (see the range of measurements for 20 in Figure 2).Almost all of this increase is due to human activities. Carbon dioxide concentrations have increased substantially since the beginning of the industrial era, rising from an annual average of 280 ppm in the late 1700s to 414 ppm in 2021 (average of five sites in Figure 1)-a 48 percent increase.Historical measurements show that the current global atmospheric concentrations of carbon dioxide, methane, and nitrous oxide are unprecedented compared with the past 800,000 years (see Figures 1, 2, and 3). ![]() Global atmospheric concentrations of carbon dioxide, methane, nitrous oxide, and certain manufactured greenhouse gases have all risen significantly over the last few hundred years (see Figures 1, 2, 3, and 4). ![]() |
