Tendon Ruptures

Category: Hindfoot, Sports, Trauma Introduction/Purpose: Achilles tendon rupture is a potentially devastating injury particularly for National Collegiate Athletic Association (NCAA) athletes. Little has been studied regarding the incidence and implications of Achilles tendon ruptures in this patient population. Better characterization of the factors commonly found in athletes who rupture their Achilles may provide clues to aid in their prevention. Methods: Achilles injuries across 16 sports among NCAA men and women during the 2004-05 to 2013-14 academic years were analyzed using the NCAA Injury Surveillance Program (NCAA-ISP). Achilles tendon rupture rates per 100,000 athlete-exposures (IR), operative rate, annual injury rate trends, re-injury rates, mechanism of injury, in-season status (pre/in/post-season) and time loss distributions were compiled and calculated. A sub-analysis of contact sports and sports played by both genders (C-BG) was performed to determine if there were significant differences in risks in patients who played in contact sports. Results: N=255 Achilles tendon injuries were identified over 10 academic years (IR: 2.17). The injury rate was higher in males compared to females (IR=2.33 vs. 1.89 respectively). Achilles injuries were most common in Men’s Basketball (IR=4.26), Soccer (IR=3.06), and Football (IR=2.69). The top three women’s sports with Achilles injury were Gymnastics (IR=16.73), Basketball (IR=3.32), and Soccer (IR=1.81). Thirty-three injuries were operative (13.1%) and 14.9% (N=38) were season-ending injuries. The average time loss was 10.65 days when excluding patients who had season/career ending injuries. Reinjury rate was 11.0% (N=28). 61.2% of all injuries occurred during the regular season (N=156) with 36.0% (N=92) and 2.7% (N=7) occurring in pre- and post- season, respectively. There was a significantly greater number of injuries in contact (N=198) versus non-contact sports (N=50) (p<0.001). Conclusion: Achilles tendon ruptures can be devastating injuries in professional and collegiate athletes. In our study, nearly 15% of all NCAA Achilles tendon ruptures resulted in season ending injuries or significant time loss and over 13% of injuries required operative management with a majority of injuries occurring during practice. In addition, a significantly higher proportion of athletes who played a contact sport had Achilles injuries. Better understanding of what circumstances more often tend to result in Achilles injuries can help establish prevention strategies.

This study investigates the perspectives and impact that personal finance education had on participants in Western Pennsylvania. The researchers begin with a literature review of personal finance courses in the United States (U.S.). The U.S. housing market collapse is also discussed as a key component of the financial crisis that is often overlooked and can be partly attributed to the lack of financial literacy. The findings of this study indicate that participants want personal finance courses offered in K-12 schools and at the collegiate level. They also want personal finance elements to be co-curricular in the K-12 setting. A recommendation based on responses from participants is that co-curricular teaching of personal finance should be tied in with math courses. The participants of this study either have benefited from personal finance lessons themselves or are a strong advocate for the teaching of personal finance in the future. The financial future does also bring worry to the different generations. Generation X is more worried about the financial choices of the upcoming generations, while Millennials and Generation Z are concerned about the future of the economy and how this will affect them.

Background: Achilles tendon (AT) ruptures are one of the most common tendon ruptures, but there have been no studies investigating these injuries in the United States (US) using data representative of the entire US population. Purpose/Hypothesis: The purpose of this study was to determine the incidence and risk factors for AT ruptures in the US. We hypothesized that male sex, older age, and sport participation would increase the risk for AT ruptures. Study Design: Descriptive epidemiology study. Methods: All patients presenting to an emergency department with ruptured AT in the US from 2012 through 2016 were selected from the National Electronic Injury Surveillance System (NEISS) database. Incidence was calculated for sex, race, and age. AT ruptures were characterized based on the mechanism of injury, with subanalyses performed on sport-related AT ruptures to examine sex-, race-, and age-related differences. Results: From 2012 to 2016, a significant increase in the incidence of AT ruptures was observed, from 1.8 per 100,000 person-years in 2012 to 2.5 per 100,000 person-years in 2016 ( P < .01), for an overall incidence of 2.1 per 100,000 person-years. The majority of AT ruptures occurred in male compared with female patients, with an incidence rate ratio of 3.5 ( P < .01). The largest overall incidence of AT ruptures occurred in those aged 20-39 years for male patients (5.6/100,000 person-years) and in those aged 40-59 years for female patients (1.2/100,000 person-years). The largest rise in the incidence of AT ruptures during the study period was observed in patients aged 40-59 years (78% increase). The most common injury mechanism was participation in a sport or recreational activity (81.9% of all injuries), with basketball being the most common overall cause of AT ruptures. Conclusion: While AT ruptures in the US most commonly occur in young male patients (20-39 years old), the largest rise in the incidence was observed in middle-aged patients (40-59 years old), with participation in recreational sports being the most likely mechanism. Recognizing high-risk patients can help physicians counsel them and recommend strategies for injury prevention.

Prostate adenocarcinoma is the most common malignant tumor of men in the United States and is the third leading cause of death in men. Despite attempts at early detection, there will be 244,000 new cases and 44,000 deaths from the disease in the United States in 1995. Therapeutic progress against this disease is hindered by an incomplete understanding of prostate epithelial cell biology, the availability of human tissues for in vitro experimentation, slow dissemination of information between prostate cancer research teams and the increasing pressure to “ stretch” research dollars at the same time staff reductions are occurring.To meet these challenges, we have used the correlative microscopy (CM) and client/server (C/S) computing to increase productivity while decreasing costs. Critical elements of our program are as follows:1) Establishing the Western Pennsylvania Genitourinary (GU) Tissue Bank which includes >100 prostates from patients with prostate adenocarcinoma as well as >20 normal prostates from transplant organ donors.

In recent years it became apparent that we needed to improve productivity and efficiency in the Microscopy Laboratories in GE Plastics. It was realized that digital image acquisition, archiving, processing, analysis, and transmission over a network would be the best way to achieve this goal. Also, the capabilities of quantitative image analysis, image transmission etc. available with this approach would help us to increase our efficiency. Although the advantages of digital image acquisition, processing, archiving, etc. have been described and are being practiced in many SEM, laboratories, they have not been generally applied in microscopy laboratories (TEM, Optical, SEM and others) and impact on increased productivity has not been yet exploited as well.In order to attain our objective we have acquired a SEMICAPS imaging workstation for each of the GE Plastic sites in the United States. We have integrated the workstation with the microscopes and their peripherals as shown in Figure 1.

Communities Of Interest

Every ten years, the United States “constructs” itself politically. On a decennial basis, U.S. Congressional districts are quite literally drawn, physically constructing political representation in the House of Representatives on the basis of where one lives. Why does the United States do it this way? What justifies domicile as the sole criteria of constituency construction? These are the questions raised in this article. Contrary to many contemporary understandings of representation at the founding, I argue that there were no principled reasons for using domicile as the method of organizing for political representation. Even in 1787, the Congressional district was expected to be far too large to map onto existing communities of interest. Instead, territory should be understood as forming a habit of mind for the founders, even while it was necessary to achieve other democratic aims of representative government.
