Distribution of uranium in the Bisbee district, Cochise County, Arizona

USGS Publications Warehouse

Wallace, Stewart R.

1956-01-01

The Bisbee district has been an important source of copper for many years, and substantial amounts of lead and zinc ore and minor amounts of manganese ore have been mined during certain periods. The copper deposits occur both as low-grade disseminated ore in the Sacramento Hill stock and as massive sulfide (and secondary oxide and carbonate) replacement bodies in Paleozoic limestones that are intruded by the stock and related igneous bodies. The lead-zinc production has come almost entirely from limestone replacement bodies. The disseminated ore exhibits no anomalous radioactivity, and samples from the Lavender pit contain from 0.002 to less than 0.001 percent equivalent uranium. The limestone replacement ores are distinctly radioactive and stoping areas can be readily distinguished from from unmineralized ground on the basis of radioactivity alone. The equivalent uranium content of the copper replacement ores ranges from 0.002 to 0.014 percent and averages about 0.005 percent; the lead-zinc replacement ores average more than 0.007 percent equivalent uranium. Most of the uranium in the copper ores of the district is retained in the smelter slag of a residual concentrate; the slag contains about 0.009 percent equivalent uranium. Uranium carried off each day by acid mine drainage is roughly equal to 1 percent of that being added to the slag dump. Although the total amount of uranium in the district is large, no minable concentrations of ore-grade material are known; samples of relatively high-grade material represent only small fractions of tons at any one locality.

To detect the effects of androgen receptor (AR) on cyclic mechanical stretch-modulated proliferation of C2C12 myoblasts and its pathways: roles of IGF-1, PI3K and MAPK. C2C12 were randomly divided into five groups: un-stretched control, six or 8 h of fifteen percent stretch, and six or 8 h of twenty percent stretch. Cyclic mechanical stretch of C2C12 were completed using a computer-controlled FlexCell Strain Unit. Cell proliferation and IGF-1 concentration in medium were detected by CCK8 and ELISA, respectively. Expressions of AR and IGF-1R, and expressions and activities of PI3K, p38 and ERK1/2 in stretched C2C12 cells were determined by Western blot. ①The proliferation of C2C12 cells, IGF-1 concentration in medium, expressions of AR and IGF-1R, and activities of PI3K, p38 and ERK1/2 were increased by 6 h of fifteen percent stretch, while decreased by twenty percent stretch for six or 8 h ②The fifteen percent stretch-increased proliferation of C2C12 cells was reversed by AR inhibitor, Flutamide. ③The increases of AR expression, activities of PI3K, p38 and ERK1/2 resulted from fifteen percent stretch were attenuated by IGF-1 neutralizing antibody, while twenty percent stretch-induced decreases of the above indicators were enhanced by recombinant IGF-1. ④Specific inhibitors of p38, ERK1/2 and PI3K all decreased the expression of AR in fifteen percent and twenty percent of stretched C2C12 cells. Cyclic mechanical stretch modulated the proliferation of C2C12 cells, which may be attributed to the alterations of AR via IGF-1-PI3K/Akt and IGF-1-MAPK (p38, ERK1/2) pathways in C2C12 cells.

Schildhauer, T A; Josten, Ch; Muhr, G

2006-01-01

Presentation of a new triangular osteosynthesis technique that permits early weight-bearing in vertically unstable sacral fractures. : Retrospective evaluation of a consecutive series. Level I trauma center. Thirty-four patients, twenty-eight of whom were poly-traumatized, all with vertically unstable sacral fractures. This group included eight women and twenty-six men, with a mean age of thirty-five years. Average time between trauma and definite operation was thirteen days (range 0 to 28 days). All patients underwent triangular osteosynthesis using a combination of a vertical vertebro-pelvic distraction osteosynthesis (pedicle screw system) and a transverse fixation of the sacrum fracture with either iliosacral screws or trans-sacral plating. Immediate postoperative weight-bearing was permitted postoperatively. Nineteen patients were treated with early progressive weight-bearing and advanced to full weight-bearing, on average, after twenty-three days (range 8 to 70 days). Three of the thirty-four patients (9 percent) experienced loosening of hardware, including two patients (6 percent) who required secondary intervention because of loss of the original reduction. Further complications included one pulmonary embolism (3 percent), one iatrogenic nerve lesion (3 percent), one wound necrosis (3 percent), and two local infections (6 percent). Triangular osteosynthesis is a demanding procedure that can be performed on vertically unstable sacral fractures to allow early progressive weight-bearing with an acceptable complication rate.

Clinical utility of remote monitoring of implantable cardiac devices has been previously demonstrated in several trials in the adult population. The aim of this study was to assess the clinical utility of remote monitoring in a pediatric population undergoing pacemakers implantation. The study population included 73 consecutive pediatric patients who received an implantable pacemaker. The remote device check was programmed for every 3 months and all patients had a yearly out-patient visit. Data on device-related events, hospitalization, and other clinical information were collected during remote checks and out-patient visits. During a mean follow-up of 18 ± 10 months, 470 remote transmissions were collected and analyzed. Two deaths were reported. Eight transmissions (1.7%) triggered an urgent out-patient visit. Twenty percent of transmissions reported evidence of significant clinical or technical events. All young patients and their families were very satisfied when using remote monitoring to replace out-patient visits. The ease in use, together with satisfaction and acceptance of remote monitoring in pediatric patients, brought very good results. The remote management of our pediatric population was safe and remote monitoring adequately replaced the periodic out-patient device checks without compromising patient safety. ©2015 Wiley Periodicals, Inc.

Clinical features and psychiatric comorbidity of subjects with pathological gambling behavior.

PubMed

Black, D W; Moyer, T

1998-11-01

Sociodemographic features, phenomenology, and psychiatric comorbidity of 30 subjects reporting pathological gambling behavior were examined. Twenty-three men and seven women were recruited by advertisement and word-of-mouth. They all scored higher than 5 points on the South Oaks Gambling Screen, indicating problematic gambling behaviors. They completed structured and semistructured assessments, including the Diagnostic Interview Schedule for DSM-III-R disorders (DIS), the Personality Diagnostic Questionnaire, Fourth Revision (PDQ-IV), and the Minnesota Impulsive Disorders Interview. The typical subject was a 44-year-old white married man with a mean income of $34,250 who visited a casino once or more weekly. All 30 subjects reported gambling more money than they intended to. Twenty subjects (67 percent) reported gambling as a current problem, and nine (30 percent) reported it as a past problem. Twenty-one subjects (70 percent) wanted to stop gambling but did not feel they could. According to DIS results, 18 subjects (60 percent) had a lifetime mood disorder, 19 (64 percent) a lifetime substance use disorder, and 12 (40 percent) a lifetime anxiety disorder. Based on the PDQ-IV, 26 subjects (87 percent) had a personality disorder, the most common being obsessive-compulsive, avoidant, schizotypal, and paranoid personality disorders. The sample also had a relatively high rate of antisocial personality disorder. Impulse control disorders were common, especially compulsive buying and compulsive sexual behavior. The results confirm that individuals with pathological gambling suffer substantial psychiatric comorbidity. They support continued inclusion of pathological gambling in the diagnostic category of impulse control disorders.

We noticed an increase in endometrial thickness in women with hypertension who were treated with a combination of medications, including beta-blockers. The purpose of this study was to examine whether the endometrium of hypertensive women is thicker than that of healthy women and to determine whether endometrial thickening in hypertensive women is directly related to the antihypertensive beta-blocker treatment. We compared 3 groups of postmenopausal patients as follows: (1) women with a history of essential hypertension treated with a combination of medications, including beta-blockers; (2) women with a history of hypertension treated with a combination of medications that did not include beta-blockers; and (3) healthy women without hypertension. All patients were interviewed and examined, blood tests were performed, and endometrial thickness in the anterior-posterior diameter was measured by vaginal ultrasonography. Among the exclusion criteria were diabetes or an abnormal fasting blood glucose level, obesity, hormonal medication or replacement hormonal therapy during the previous 6 months, and a history of hormonal disturbances, infertility, or polycystic ovary syndrome. Of 45 hypertensive women enrolled in the study, 22 were treated with a beta-blocker combination medication and 23 were treated with other antihypertensive medications. They were compared with 25 healthy women. There was no statistically significant difference in endometrial thickness between women treated with medications, including beta-blockers, and those who were treated with other hypotensive agents. Twenty percent of women with hypertension and none of the healthy women had endometrium >5 mm thick (P <.017; odds ratio, 8.22; 95% confidence interval, 1.22-infinity). Twenty percent of hypertensive postmenopausal women were found to have increased endometrial thickness. However, we were unable to substantiate an association between the type of treatment administered, whether beta-blockers were included, and the increase in endometrial thickness.

Robson, Sam

2017-01-01

Objective: The objective of this study was to examine the efficacy and safety of the latest multisource radiofrequency handpiece, specially designed for body area skin treatments. The new handpiece features six concentric electrodes, each connected to an independently controlled radiofrequency generator. Design and settings: This was an international multicenter study across two sites. Twenty-five patients were enrolled into the study. Patients underwent at least five sessions of body skin tightening and circumference reduction. The first four sessions were held at one-week intervals and the other 1 to 4 remaining sessions, at two-week intervals. Participants: Twenty-five patients (23 women and 2 men). Measurements: Overall change was graded by the physicians using the global aesthetic improvement scale. Patients were asked to complete satisfaction questionnaires at the end of the treatment sessions. Images were taken prior to the treatments, before every treatment session, and at the follow-up visit. Results: No adverse events were reported as a result of the treatment. Measured body weight of the patients, as monitored during the study period, was stable (±2kg). Ninety-two percent of the patients were pleased with the results and finished all the treatment sessions. Twenty-four patients (96%) saw an improvement in body shape. Ninety-two percent of the patients would recommend the treatment to others. Overall change graded by the physician by the global aesthetic improvement scale provided the following results: 44 percent of the patients had more than 75-percent improvement, 32 percent of the patients between 50- to 75-percent improvement, 20 percent of the patients had between 25- to 50-percent improvement and only four percent had less than 25-percent improvement. Conclusion: The authors’ data show that the handpiece examined provides high efficacy in skin tightening and body contouring after 5 to 8 painless treatments. Patient subjective questionnaires show very high satisfaction rates. PMID:28458771

Electronics manufacturing and assembly in Japan

In the consumer electronics industry, precision processing technology is the basis for enhancing product functions and for minimizing components and end products. Throughout Japan, manufacturing technology is seen as critical to the production and assembly of advanced products. While its population has increased less than 30 percent over twenty-five years, Japan's gross national product has increase thirtyfold; this growth has resulted in large part from rapid replacement of manual operations with innovative, high-speed, large-scale, continuously running, complex machines that process a growing number of miniaturized components. The JTEC panel found that introduction of next-generation electronics products in Japan goes hand-in-hand with introduction of new and improved production equipment. In the panel's judgment, Japan's advanced process technologies and equipment development and its highly automated factories are crucial elements of its domination of the consumer electronics marketplace - and Japan's expertise in manufacturing consumer electronics products gives it potentially unapproachable process expertise in all electronics markets.

Dougherty, P J

1999-10-01

Because caring for patients who have combat-related amputations is a discontinuous practice, military surgeons must relearn treatment techniques during each conflict. The purpose of the present long-term study (average duration of follow-up, 27.5 years) was to document the status of patients who had sustained a bilateral above-the-knee amputation in Vietnam and had been managed by the only separate amputee service in the United States Army. A review of the records of 484 battle amputees identified thirty individuals (6 percent) who had a bilateral above-the-knee amputation. Twenty-six (87 percent) of the thirty patients had been injured by a land mine or a booby trap. Fifty-three (88 percent) of the sixty limbs were amputated because of trauma, and the other seven (12 percent) were amputated secondarily because of infection. Data regarding education, employment, marriage and family life, prosthetic use, and psychological care were collected by mail or telephone for twenty-three (85 percent) of the twenty-seven surviving patients. Respondents also completed the Short Form-36 (SF-36) Health Survey. At the time of the study, five (22 percent) of the twenty-three respondents used prostheses for walking; the devices were used for an average of 7.7 hours per day. Sixteen respondents (70 percent) were or had been employed outside of the home since the time of discharge. The physical functioning score on the SF-36 questionnaire was significantly lower for the study group than it was for a group of age and gender-matched controls (p < 0.001; Student two-tailed t test). With the numbers available, no significant differences could be detected between the groups with regard to physical role functioning (p = 0.377), bodily pain (p = 0.603), general health (p = 0.407), vitality (p = 0.949), social functioning (p = 0.460), emotional role functioning (p = 0.029), or mental health (p = 0.102). The patients in the present study have led relatively normal, productive lives within the context of their physical limitations.

To compare how providers of testosterone replacement therapy (TRT) in large metropolitan cities promote androgen replacement on their patient-oriented Web sites. TRT provider Web sites were identified using Google search and the terms "Testosterone replacement" and the name of the 5 most populous US cities. These Web sites were assessed for (1) type or specialty of medical provider, (2) discussion of the benefits and risks of TRT, and (3) industry affiliations. In total, 75 Web sites were evaluated. Twenty-seven of the 75 clinics (36%) were directed by nonphysicians, 35 (47%) were overseen by nonurology or nonendocrine physicians, and only 13 (17%) were specialist managed. Fourteen of 75 (18.6%) Web sites disclosed industry relationships. Ninety-five percent of Web sites promoted the benefits of TRT including improved sex drive, cognitive improvement, increased muscle strength, and/or improved energy. Only 20 of 75 Web sites (26.6%) described any side effect of TRT. Web sites directed by specialists were twice as likely to discuss risks of TRT compared with nonspecialist providers (41% vs 20%; odds ratio = 2.77; P <.01). Nine of 75 (12%) of all Web sites actually refuted that TRT was associated with significant side effects. Urologists and endocrinologists are in the minority of providers promoting TRT on the Internet. Specialists are more likely to discuss risks associated with TRT although the majority of surveyed Web sites that promote TRT do not mention treatment risks. There is substantial variability in quality and quantity of information on provider Web sites, which may contribute to misinformation regarding this prevalent health issue.

Development of migratory behavior in northern white-tailed deer

Nelson, M.E.

1998-01-01

I examined the development of migratory behavior in northern white-tailed deer (Odocoileus virginianus) from 1975 to 1996 by radio-tracking adult females and their fawns. Of 40 migratory fawns with radio-collared mothers, all returned from winter ranges to their mothers' summer ranges, as did 36 fawns with unknown mothers. Of 1.5- to 3.0-year-old daughters with radio-collared mothers, 67-80% continued migrating with mothers to their traditional summer ranges. Eighty-four percent (16/19) of yearling dispersers continued migratory behavior after replacing their natal summer ranges with their dispersal ranges, and 88% (14/16) of these continued migrating to their natal winter ranges, some through at least 6.5 years of age. Twenty percent (4/20) of nonmigratory fawns dispersed as yearlings, and two became migratory between their dispersal summer ranges and new winter ranges, one through 4.9 years of age and another through 6.5 years. Seven fawns changed their movement behavior from migratory to nonmigratory or vice versa as yearlings or when older, indicating that migratory behavior is not under rigid genetic control. Thus, the adaptiveness of migration must depend upon natural selection operating upon varying capacities and propensities to learn and mimic long-distance movements and not upon migratory behavior directly.

2012-12-01

The purpose of this study was to adapt the twenty-six-item Communication Skills Attitude Scale (CSAS) developed for medical students for use among dental students and to test the psychometric properties of the modified instrument. The sample consisted of 250 students (an 80.1 percent response rate) in years D1 to D4 at a dental school in Washington, DC. The mean age of participants was 26.6 years with a range from twenty-one to forty-two years. Slightly more than half of the participants were female (52.4 percent) and were African American or of African descent (51.7 percent). Principal components analysis was used to test the psychometric properties of the instrument. The index that resulted measured both positive and negative attitudes toward learning communications skills. The final twenty-four-item scale had good internal consistency (Cronbach's alpha=0.87), and the study obtained four important factors-Learning, Importance, Quality, and Success-that explained a significant portion of the variance (49.1 percent). Stratified analysis by demographic variables suggested that there may be gender and ethnic differences in the students' attitudes towards learning communication skills. The authors conclude that the CSAS modified for dental students, or DCSAS, is a useful tool to assess attitudes towards learning communication skills among dental students.

Collet, D

1992-01-01

Twenty-eight surgeons, members of the Société Française de Chirurgie Endoscopique et de Radiologie Opératoire, took part in this multicenter study, carried out between March 1989 and January 1991. Nine hundred and thirty-seven patients were entered into the study, 934 of whom presented with biliary lithiasis and 3 with gallbladder polyps. Biliary colic was found in 918 (98 percent) of patients. One hundred and twenty-five patients (13.3 percent) presented with acute cholecystitis. Laparoscopic cholecystectomy had to be converted to traditional laparotomy in 50 cases (5.3 percent). The most frequent causes of conversion were the presence of cholecystitis (34 percent) and the occurrence of hemorrhage which could not be controlled laparoscopically (18 percent). There was one death (mortality rate: 0.1 percent) and there were 37 postoperative complications (morbidity rate: 3.9 percent) which required reoperation in 11 instances: 4 laparatomies, 5 laparoscopies and 2 ultrasonography guided drainages. The mean duration of postoperative hospital stay for patients without complications or conversion was 3.8 days. These results show both the limits and the advantages of laparoscopic cholecystectomy. This new technique is now well established and should be added to other therapies used in the treatment of patients with biliary lithiasis.

To determine European intensive care unit (ICU) nurses' knowledge of guidelines for preventing central venous catheter-related infection from the Centers for Disease Control and Prevention. Multicountry survey (October 2006-March 2007). Twenty-two European countries. ICU nurses. Using a validated multiple-choice test, knowledge of ten recommendations for central venous catheter-related infection prevention was evaluated (one point per question) and assessed in relation to participants' gender, ICU experience, number of ICU beds, and acquisition of a specialized ICU qualification. We collected 3405 questionnaires (70.9% response rate); mean test score was 44.4%. Fifty-six percent knew that central venous catheters should be replaced on indication only, and 74% knew this also concerns replacement over a guidewire. Replacing pressure transducers and tubing every 4 days, and using coated devices in patients requiring a central venous catheter >5 days in settings with high infection rates only were recognized as recommended by 53% and 31%, respectively. Central venous catheters dressings in general are known to be changed on indication and at least once weekly by 43%, and 26% recognized that both polyurethane and gauze dressings are recommended. Only 14% checked 2% aqueous chlorhexidine as the recommended disinfection solution; 30% knew antibiotic ointments are not recommended because they trigger resistance. Replacing administration sets within 24 hrs after administering lipid emulsions was recognized as recommended by 90%, but only 26% knew sets should be replaced every 96 hrs when administering neither lipid emulsions nor blood products. Professional seniority and number of ICU beds showed to be independently associated with better test scores. Opportunities exist to optimize knowledge of central venous catheter-related infection prevention among European ICU nurses. We recommend including central venous catheter-related infection prevention guidelines in educational curricula and continuing refresher education programs.

2009-05-01

Portal vein thrombosis (PVT) refers to a thrombosis that occurs in the extrahepatic portal venous system in the presence or absence of underlying liver disease. The clinical presentation of PVT is extremely variable and there is no absolute consensus on its investigation and management. A paucity of literature examining this clinical entity in the district general hospital is observed. We reviewed the experience of two medium-sized district general hospitals in the UK. Twenty-five patients, who were diagnosed with PVT, were identified from the electronic databases of the two hospitals from 1994 to 2007. Fifty-six percent of patients were females with a median age of 59 years. Seventy-six percent of patients had an identifiable comorbidity at presentation, the most common being chronic liver disease. The most frequently presenting symptom was abdominal pain and distension (60%). Twenty-four percent of patients presented with upper gastrointestinal bleeding secondary to oesophageal and/or gastric varices. Abdominal ultrasound and computed tomographical imaging were the imaging modalities most commonly used to diagnose PVT, although abdominal ultrasound missed 12% of patients subsequently diagnosed by other methods. Fifty percent of patients, who had a thrombophilia screen, were found to have a coagulopathy. Twenty-eight percent of patients were anticoagulated with warfarin with no adverse bleeding events observed. Forty-four percent of patients were placed on an endoscopic variceal band ligation programme. Nine patients died over the study period from either upper gastrointestinal bleeding, end-stage liver failure or biliary sepsis. The acturial 5-year survival was 72%. The mortality from PVT is low and survival is related to the underlying cause. Although the diagnosis of PVT remains uncommon outside the specialist centre, both specialist and nonspecialist physicians must remain mindful of this important condition.

Twenty-three percent of the inpatient population of a psychopaedic hospital in New Zealand were found to have engaged in self-injury during a six month observation period. Of the 50 male and 34 female patients studied, 62 exhibited single self-injury, and 22 multiple self-injury. Self-injury consisted of head banging, face slapping, skin picking, hair pulling, self-biting, regurgitation/vomiting, and excessive painful masturbation. Twenty-five percent of these patients indulged in forms of self-injury which was potentially seriously harmful to themselves if not immediately treated. The overall percentage of such patients in this hospital was found to be much higher than that reported elsewhere.

Cell-mediated immunity to homologous spermatozoa following vasectomy in the human male.

PubMed Central

Nagarkatti, P S; Rao, S S

1976-01-01

Cell-mediated immunity (CMI) to homologous spermatozoal antigens was studied in sixty-two males following vasectomy of a duration of 1-10 years. A group of twenty-two normal, fertile non-vasectomized males was also included in the study. The inhibition in the leucocyte migration test (LMT), in the presence of spermatozoal antigen, was taken as an index of CMI. Twenty of the sixty-two vasectomized males (32.2 percent) showed a positive LMT reaction. When the results were analysed with reference to the duration of vasectomy, it was noted that four cases each (22.2 percent), showed a positive LMT reaction in the groups 0-2 years, and 3.5 years. On the other hand twelve cases gave a positive reaction in the group 6-10 years (46.1 percent). It appears that the incidence of CMI to spermatozoa increases with the duration in vasectomy.

Machine Learned Replacement of N-Labels for Basecalled Sequences in DNA Barcoding.

PubMed

Ma, Eddie Y T; Ratnasingham, Sujeevan; Kremer, Stefan C

2018-01-01

This study presents a machine learning method that increases the number of identified bases in Sanger Sequencing. The system post-processes a KB basecalled chromatogram. It selects a recoverable subset of N-labels in the KB-called chromatogram to replace with basecalls (A,C,G,T). An N-label correction is defined given an additional read of the same sequence, and a human finished sequence. Corrections are added to the dataset when an alignment determines the additional read and human agree on the identity of the N-label. KB must also rate the replacement with quality value of in the additional read. Corrections are only available during system training. Developing the system, nearly 850,000 N-labels are obtained from Barcode of Life Datasystems, the premier database of genetic markers called DNA Barcodes. Increasing the number of correct bases improves reference sequence reliability, increases sequence identification accuracy, and assures analysis correctness. Keeping with barcoding standards, our system maintains an error rate of percent. Our system only applies corrections when it estimates low rate of error. Tested on this data, our automation selects and recovers: 79 percent of N-labels from COI (animal barcode); 80 percent from matK and rbcL (plant barcodes); and 58 percent from non-protein-coding sequences (across eukaryotes).

Comparing replacement rates under private and federal retirement systems.

PubMed

Martin, Patricia P

One measure of the adequacy of retirement income is replacement rate - the percentage of pre-retirement salary that is available to a worker in retirement. This article compares salary replacement rates for private-sector employees of medium and large private establishments with those for federal employees under the Civil Service Retirement System and the Federal Employees Retirement System. Because there is no standard benefit formula to represent the variety of formulas available in the private sector, a composite defined benefit formula was developed using the characteristics of plans summarized in the Bureau of Labor Statistics Medium and Large Employer Plan Survey. The resulting "typical" private-sector defined benefit plan, with an accompanying defined contribution plan, was then compared with the two federal systems. The Civil Service Retirement System (CSRS) is a stand-alone defined benefit plan whose participants are not covered by Social Security. Until passage of the 1983 Amendments to Social Security Act, it was the only retirement plan for most federal civilian employees. Provisions of the 1983 Amendments were designed to restore long-term financial stability to the Social Security trust funds. One provision created the Federal Employees Retirement System (FERS), which covers federal employees hired after 1983. It was one of the provisions designed to restore long-term financial stability to the Social Security trust funds. FERS employees contribute to and are covered by Social Security. FERS, which is a defined benefit plan, also includes a basic benefit and a 401(k)-type plan known as the Thrift Savings Plan (TSP). To compare how retirees would fare under the three different retirement systems, benefits of employees retiring at age 65 with 35 years of service were calculated using hypothetical workers with steady earnings. Workers were classified according to a percentage of the average wage in the economy: low earners (45 percent), average earners (100 percent) high earners (160 percent), and maximum earners (earnings at the taxable maximum amount). Overall, this analysis found that: Excluding Social Security benefits and TSP and defined contribution annuities, CSRS retirees have a higher pre-retirement salary replacement rate than either FERS or private-sector retirees. Private-sector retirees, however, have higher replacement rate than their FERS counterparts. Including Social Security benefits but not TSP and defined contribution plan annuities, CSRS retirees who are maximum earners have a higher pre-retirement salary replacement rate (despite receiving no Social Security benefits) than FERS retirees with the same earnings. Private-sector retirees in all earnings categories have a higher replacement rate than federal retirees with the same earnings. Including Social Security and TSP and defined contribution plan annuities, private-sector retirees in all earnings categories have a higher replacement rate than federal retirees, but their rate is close to that of FERS retirees. The rate is higher for FERS retirees than for CSRS retirees in all earnings categories. This analysis shows that replacement creates could exceed 100 percent for FERS employees who contribute who contribute 6 percent of earnings to the TSP over full working career. Private-sector replacement rates were quite similar for those with both a defined benefit and a defined contribution pension plan. Social Security replacement rates make up the highest proportion of benefits for th private sector's lowest income quartile group. The replacement rate for 401(k) plans and the TSP account for a higher proportion of benefits than does Social Security for all other income groups, assuming the absence of a defined benefit plan.

The Latin American Society of Nephrology and Arterial Hypertension's Dialysis and Transplant Registry was chartered in 1991. It collects information on ESRD and its treatment in 20 countries of the region. The prevalence of patients on renal replacement therapy (RRT) increased from 129 pmp in 1992 to 447 pmp in 2004; in 2004, 56% of the patients were on hemodialysis, 23% on peritoneal dialysis, and 21% had a functioning kidney graft. The highest rates of prevalence were reported in Puerto Rico (1027 pmp), Chile (686 pmp), and Uruguay (683 pmp). Hemodialysis was widely used, except in El Salvador, Mexico, Guatemala, Nicaragua, and the Dominican Republic, where peritoneal dialysis predominated. Incidence rate increased from 27.8 pmp to 147 pmp in the same period of observation; the lowest rate was reported in Guatemala (11.4 pmp) and the highest in Puerto Rico (337.4 pmp). Diabetes mellitus was the leading cause of renal failure in incident patients; the highest rates were reported in Puerto Rico (62.2%) and Mexico (60%). Forty-four percent of the incident population were older than 65 years. Access to renal replacement therapy was universal in Argentina, Brazil, Chile, Cuba, Puerto Rico, Uruguay, and Venezuela, while was restricted in other countries. Main causes of death in dialysis were cardiovascular (44%) and infectious disease (26%). The rate of renal transplantation increased from 3.7 pmp in 1987 to 14.5 in 2004; fifty-three percent of the organs came from cadavers. Overall, donation rate was 5.9 pmp. In conclusion, the prevalence and incidence rates have increased over the years, and diabetes mellitus has emerged as the leading cause of kidney disease in the region. Although the rate of kidney transplantation has increased, the number remains insufficient to match the growing demand. The implementation of renal health programs in the region is urgently needed.

Low Fertility at the Turn of the Twenty-First Century

PubMed Central

Morgan, S. Philip; Taylor, Miles G.

2010-01-01

In the past few decades, demographic concerns have shifted from rapid population growth fueled by high fertility to concerns of population decline produced by very low, sub-replacement fertility levels. Once considered a problem unique to Europe or developed nations, concerns now center on the global spread of low fertility. Nearly half of the world's population now lives in countries with fertility at or below replacement levels. Further, by the mid-twenty-first century three of four countries now described as developing are projected to reach or slip below replacement fertility. We review the research on low fertility through the predominant frameworks and theories used to explain it. These explanations range from decomposition and proximate determinant frameworks to grand theories on the fundamental causes underlying the pervasiveness and spread of low fertility. We focus on the ability of theory to situate previous and future findings and conclude with directions for furthur research. PMID:20376287

The number of applicants to dental schools in the United States continues to rise at a double-digit rate, 12 percent from 2005 to 2006 and 14 percent from 2006 to 2007. The number of applicants to the 2006 and 2007 years' entering classes of U.S. dental schools was 12,500 and 13,700, respectively. The number of first-time enrollees (4,600) in 2007 was the highest recorded since 1989. Men continue to comprise the majority of all applicants, 55 percent in 2006 and 53 percent in 2007. However, the percentage of women applicants to each school ranged from a third to more than half. Underrepresented minority (URM) applicants comprised 12 percent of the applicant pools in both 2006 and 2007. For the 2007 entering class, URM enrollees comprised 13 percent of enrollees. As in previous years, in 2007, the largest number of applicants and enrollees came from states that are among the largest in population in the United States: California, Texas, New York, and Florida. Grade point average and Dental Admission Test scores were the highest in more than a decade. More than three out of four of the 2007 first-time, first-year enrollees earned a baccalaureate degree either in biological/life or physical sciences or in health. Regardless of major field of study, the percent rates of enrollment generally exceeded 30 percent, though there were exceptions (e.g., engineering and education). The majority of enrollees to the 2007 entering classes were twenty-two or twenty-three years of age.

Reliability and Maintainability Analysis of a High Air Pressure Compressor Facility

NASA Technical Reports Server (NTRS)

Safie, Fayssal M.; Ring, Robert W.; Cole, Stuart K.

2013-01-01

This paper discusses a Reliability, Availability, and Maintainability (RAM) independent assessment conducted to support the refurbishment of the Compressor Station at the NASA Langley Research Center (LaRC). The paper discusses the methodologies used by the assessment team to derive the repair by replacement (RR) strategies to improve the reliability and availability of the Compressor Station (Ref.1). This includes a RAPTOR simulation model that was used to generate the statistical data analysis needed to derive a 15-year investment plan to support the refurbishment of the facility. To summarize, study results clearly indicate that the air compressors are well past their design life. The major failures of Compressors indicate that significant latent failure causes are present. Given the occurrence of these high-cost failures following compressor overhauls, future major failures should be anticipated if compressors are not replaced. Given the results from the RR analysis, the study team recommended a compressor replacement strategy. Based on the data analysis, the RR strategy will lead to sustainable operations through significant improvements in reliability, availability, and the probability of meeting the air demand with acceptable investment cost that should translate, in the long run, into major cost savings. For example, the probability of meeting air demand improved from 79.7 percent for the Base Case to 97.3 percent. Expressed in terms of a reduction in the probability of failing to meet demand (1 in 5 days to 1 in 37 days), the improvement is about 700 percent. Similarly, compressor replacement improved the operational availability of the facility from 97.5 percent to 99.8 percent. Expressed in terms of a reduction in system unavailability (1 in 40 to 1 in 500), the improvement is better than 1000 percent (an order of magnitude improvement). It is worthy to note that the methodologies, tools, and techniques used in the LaRC study can be used to evaluate similar high value equipment components and facilities. Also, lessons learned in data collection and maintenance practices derived from the observations, findings, and recommendations of the study are extremely important in the evaluation and sustainment of new compressor facilities.

The Infection Rate of Metal-on-Metal Total Hip Replacement Is Higher When Compared to Other Bearing Surfaces as Documented by the Australian Orthopaedic Association National Joint Replacement Registry.

PubMed

Huang, Phil; Lyons, Matt; O'Sullivan, Michael

2018-02-01

Despite the well-documented decline in the use of metal-on-metal (MoM) implants over the last decade, there are still controversies regarding whether all MoM implants are created equally. Complications such as elevated serum metal ion levels, aseptic lymphocyte-dominated vasculitis-associated lesion (ALVAL) and pseudotumours have all been well documented, but recent studies suggest increased risk of infection with MoM bearing surfaces. Most of these studies however have small patient numbers. The purpose of this study was to examine the cumulative incidence of revision for infection of MoM bearing surfaces in primary hip arthroplasty at a national and single-surgeon level. Data was collected from the Australian Orthopaedic Association National Joint Replacement Registry, which contains over 98% of all arthroplasties performed in Australia since 2001. The cumulative incidence of revision for infection was extracted at a national level and single-surgeon level. Two hundred seventy-six thousand eight hundred seventy-eight subjects were documented in the Australian registry. The 10-year cumulative percent revision for infection of MoM bearing surfaces in primary total hip replacement (THR) was 2.5% at a national level, compared to 0.8% for other bearing surfaces. The senior author contributed 1755 subjects with 7-year follow-up and a cumulative percent revision for infection of MoM bearing surfaces in primary THR of 36.9%, compared to 2.0% for other bearing surfaces. The cumulative percent of revision of MoM bearing surfaces is higher compared to other bearing surfaces; this is especially pronounced in cumulative percent of revision for infection. There was a higher cumulative percent of revision for infection in MoM bearings surfaces (in particular, large-head MoM) compared to other bearing surfaces at both the national and individual-surgeon level.

97% accuracy of intra-articular glenohumeral injection with a modified (Delaware) posterior bone touch technique.

PubMed

Axe, Jeremie M; Axe, Michael J

2013-10-01

Unguided approaches have not demonstrated evidence of highly accurate intra-articular glenohumeral injections. The purpose of this study was to assess the accuracy of a posterior approach bone touch technique in conscious subjects without shoulder pathology as a first step in developing an accurate, reliable technique for use in patients. Twenty-six young subjects (age 22-26) without shoulder pathology (BMI 24 +/- 3), had bilateral shoulders injected while awake and seated. A 20 gauge 3.5-inch needle was introduced 1.5 cm below the scapular spine mid-way between the posterior lateral acromial corner and the posterior axillary crease. In Trial I, 20 shoulders were injected. After touching the humerus, the arm was oscillated. The needle advanced to 4-5 cm and 10 mL of dye injected. Pop and ease of flow were recorded. Immediate room change, spot fluoroscopy, and independent experienced radiology reading followed. In Trial II, 32 shoulders were injected. The technique was modified to touching the humerus, externally rotating the arm 25 degrees, and while remaining in bone contact, delivering 10 mL of dye. The same data as Trial I was recorded. In Trial I, 14/20 (70 percent) had dye within the glenohumeral joint. Five of seven failures were too anterior showing dye around the subscapularis muscle and all were associated with a pop. In Trial II, 31/32 (97 percent) had dye within glenohumeral joint. Twenty-three of 32 (72 percent) had a "pop," including the failure. Overall, 45/52 (87 percent) had dye within glenohumeral joint. Thirty-one of 52 (71 percent) of all shoulders had a "pop." Twenty-three of 52 (44 percent) shoulders had pain, resolving within 24 hours. A modified (Delaware) posterior bone touch technique for glenohumeral joint injection is 97 percent accurate in conscious healthy young subjects. Pop and ease of flow are not always indicative of correct needle placement. This study serves as an important first step in determining an optimum approach for injecting pathologic glenohumeral joints with corticosteroids or hyaluronic acid. IV Case Series.

A self applied and anonymous enquiry was answered by 948 teenagers (600 female), participating in an integral health education plan and coming from a school located in a low income community of Metropolitan Santiago. Twenty nine percent came from single or foster parent families and 18.4% of parents were separated. Nineteen percent of women and 9.8% of men felt that they were not loved by their parents; 30.5% of women and classified as bad or regular their relationship with their fathers and 22.1% of men similarly classified their relationship with their mothers. Eighteen percent of men and 16.5% of women ignored their parent's educational level. Ten to 24% had a negative self image and 50% were unsure about their study goals. Forty eight percent of men and 25.5% of women had get drunk; 24.1 and 12.8% had smoked marihuana. Half of the sample manifested attraction to dangerous situations; 22% had participated in quarrels and 34% had attacked other people. Twenty three percent of men and 35% of women had considered committing suicide. It is concluded that the lack of affection, a deteriorated self image, difficult parental relationships and orientation toward violence appear as the main problems in this sample of teenagers.

Multiple forms of proof were used to validate age claims. Sociodemographic, activities of daily living, and medical history data were collected. Age range was 110 to 119. Fifty-nine percent had Barthel Index scores in the partially to totally dependent range, whereas 41% required minimal assistance or were independent. Few subjects had a history of clinically evident vascular-related diseases, including myocardial infarction (n=2, 6%) and stroke (n=4, 13%). Twenty-two percent (n=7) were taking medications for hypertension. Twenty-five percent (n=8) had a history of cancer (all cured). Diabetes mellitus (n=1, 3%) and Parkinson's disease (n=1, 3%) were rare. Osteoporosis (n=14, 44%) and cataract history (n=28, 88%) were common. Data collected thus far suggest that supercentenarians markedly delay and even escape clinical expression of vascular disease toward the end of their exceptionally long lives. A surprisingly substantial proportion of these individuals were still functionally independent or required minimal assistance.

2010-11-01

The purpose of this study was to determine awareness and compliance with recommended running shoe selection, sizing, and replacement guidelines among U.S. Army soldiers. Soldiers (n = 524) attending training at Fort Sam Houston, Texas completed self-report questionnaires and a foot assessment, which included measurement of foot size and arch height index. Researchers examined each soldier's running shoes for type, wear pattern, and general condition. Thirty-five percent of the soldiers wore shoes that were inappropriately sized; 56.5% wore shoes that were inappropriate for their foot type. Thirty-five percent of the soldiers had excessively worn shoes and 63% did not know recommended shoe replacement guidelines. Further efforts may be necessary to ensure that soldiers are aware of and compliant with recommended running shoe selection, sizing, and replacement guidelines. Future research is needed to determine whether adherence to these guidelines has a favorable effect on reducing risk of overuse injury.

General surgery graduates may be ill prepared to enter rural or community surgical practice.

PubMed

Gillman, Lawrence M; Vergis, Ashley

2013-06-01

Rural/community surgery presents unique challenges to general surgeons. Not only are they required to perform "classic" general surgery procedures, but they are also often expected to be competent in other surgical disciplines. Final-year Canadian-trained residents in general surgery were asked to complete the survey. The survey explored chief residents' career plans for the following year and whether or not they would independently perform various procedures, some general surgical, and others now considered within the domain of the subspecialties. Sixty-four residents (71%) completed the survey. Twenty percent planned to undertake a rural surgical practice, 17% an urban community practice, and 55% had confirmed fellowships. Most residents (>90%) expressed comfort with basic general surgical procedures. However, residents were less comfortable with subspecialty procedures that are still performed by general surgeons in many rural practices. More than half of graduating general surgery residents are choosing subspecialty fellowship training over proceeding directly to practice. Those choosing a rural or community practice are likely to feel ill prepared to replace existing surgeons. Copyright © 2013 Elsevier Inc. All rights reserved.

Internet-related health care firms have accelerated through the life cycle of capital finance and organizational destiny, including venture capital funding, public stock offerings, and consolidation, in the wake of heightened competition and earnings disappointments. Venture capital flooded into the e-health sector, rising from $3 million in the first quarter of 1998 to $335 million two years later. Twenty-six e-health firms went public in eighteen months, raising $1.53 billion at initial public offering (IPO) and with post-IPO share price appreciation greater than 100 percent for eighteen firms. The technology-sector crash hit the e-health sector especially hard, driving share prices down by more than 80 percent for twenty-one firms. The industry now faces an extended period of consolidation between e-health and conventional firms.

Postoperative pain control is essential for optimal patient outcomes. Ketorolac is an attractive alternative for achieving pain control postoperatively, but concerns over postoperative bleeding have limited its use. Computer searches of the MEDLINE, EMBASE, and Cochrane Library databases were performed. Twenty-seven double-blind, randomized, controlled studies were reviewed by two independent investigators for the incidence of adverse events, including postoperative bleeding. Comprehensive meta-analysis software was used to evaluate the differences between ketorolac and control groups. Twenty-seven studies with 2314 patients were analyzed. Postoperative bleeding occurred in 33 of 1304 patients (2.5 percent) in the ketorolac group compared with 21 of 1010 (2.1 percent) in the control group (OR, 1.1; 95 percent CI, 0.61 to 2.06; p = 0.72). Adverse events were similar in the groups, 31.7 percent in the control group and 27.9 percent in the ketorolac group (OR, 0.64; 95 percent CI, 0.41 to 1.01; p = 0.06). There was a lower incidence of adverse effects with low-dose ketorolac (OR, 0.49; 95 percent CI, 0.27 to 0.91; p = 0.02). Pain control with ketorolac was superior to controls and equivalent to opioids. This is the first meta-analysis of randomized controlled trials examining whether there is increased postoperative bleeding with ketorolac. Postoperative bleeding was not significantly increased with ketorolac compared with controls, and adverse effects were not statistically different between the groups. Pain control was found to be superior with ketorolac compared with controls. Ketorolac should be considered for postoperative pain control, especially to limit the use of opioid pain medications.

2014-01-01

To understand perceptions of faculty and students about attendance policies in baccalaureate nursing programs. Classroom attendance is an issue of debate across academic disciplines. A mixed-methods study was conducted using qualitative data from a stratified random sample of 65 accredited baccalaureate nursing programs; 591 students and 91 faculty from 19 schools responded. Sixty-two percent of faculty thought students who missed class exhibited unprofessional behavior; 69 percent believed students who missed class were less successful in the clinical setting. Students (57 percent) and faculty (66 percent) believed there should be an attendance policy. Twenty-nine students reported needing a break in workload (16.8 percent) or did not find class time valuable (11.8 percent). Variability exists in student and faculty beliefs regarding attendance policies. Understanding these viewpoints and utilizing creative teaching approaches will facilitate learning and create an environment of teamwork and mutual respect.

2015-09-01

The literature has seen a surge in research on the mental health impacts of technologies such as Facebook, video games, and massively-multiplayer online role-playing games such as World of Warcraft, but little is known regarding the mental health impact of non-video role-playing games, such as Dungeons & Dragons. The present study examines how psychiatrists' perceive role-playing games and whether they play them. Psychiatrists at a tertiary care centre in Canada completed a questionnaire assessing history of playing role-playing games and whether they associate them with psychopathology. Forty-eight psychiatrists responded. Twenty-three percent have played a role-playing game over their lifetimes. Twenty-two percent believed there was an association between psychopathology and role-playing games. A majority of psychiatrists who responded do not associate role-playing games with psychopathology. Implications for clinical practice and future research are discussed.

Tribological and microstructural comparison of HIPped PM212 and PM212/Au self-lubricating composites

NASA Technical Reports Server (NTRS)

Bogdanski, Michael S.; Sliney, Harold E.; Dellacorte, Christopher

1992-01-01

The feasibility of replacing the silver with the volumetric equivalent of gold in the chromium carbide-based self-lubricating composite PM212 (70 wt. percent NiCo-Cr3C2, 15 percent BaF2/CaF2 eutectic) was studied. The new composite, PM212/Au has the following composition: 62 wt. percent NiCo-Cr3C2, 25 percent Au, 13 percent BaF2/CaF2 eutectic. The silver was replaced with gold to minimize the potential reactivity of the composite with possible environmental contaminants such as sulfur. The composites were fabricated by hot isostatic pressing (HIPping) and machined into pin specimens. The pins were slid against nickel-based superalloy disks. Sliding velocities ranged from 0.27 to 10.0 m/s and temperatures from 25 to 900 C. Friction coefficients ranged from 0.25 to 0.40 and wear factors for the pin and disk were typically low 10(exp -5) cu mm/N-m. HIPped PM212 measured fully dense, whereas PM212/Au had 15 percent residual porosity. Examination of the microstructures with optical and scanning electron microscopy revealed the presence of pores in PM212/Au that were not present in PM212. Though the exact reason for the residual porosity in PM212/Au was not determined, it may be due to particle morphology differences between the gold and silver and their effect on powder metallurgy processing.

2012-05-01

In two previous studies of dental students' attitudes about the VitalSource Bookshelf, a digital library of dental textbooks, students expressed negative opinions about owning and reading electronic textbooks. With the assumption that dentists would find the digital textbooks useful for patient care, the authors surveyed recent graduates to determine if their attitude toward the VitalSource Bookshelf had changed. A brief survey was sent to 119 alumni from the classes of 2009 and 2010 of one U.S. dental school. Forty-seven (39.5 percent) completed the questionnaire. Eighteen respondents (48.3 percent) reported using the e-textbooks often or sometimes. The twenty-nine dentists who said they have not used the collection since graduation reported preferring print books or other online sources or having technical problems when downloading the books to a new computer. Only five respondents selected the VitalSource Bookshelf as a preferred source of professional information. Most of the respondents reported preferring to consult colleagues (37.8 percent), the Internet (20 percent), or hardcopy books (17.8 percent) for information. When asked in an open-ended question to state their opinion of the Bookshelf, nineteen (42.2 percent) responded positively, but almost one-third of these only liked the search feature. Six respondents reported that they never use the program. Twenty-two said they have had technical problems with the Bookshelf, including fifteen who have not been able to install it on a new computer. Many of them said they have not followed up with either the dental school or VitalSource support services to overcome this problem. Our study suggests that dentists, similar to dental students, dislike reading electronic textbooks, even with the advantage of searching a topic across more than sixty dental titles.

Osteonecrosis of the femoral head in sickle cell disease: prevalence, comorbidities, and surgical outcomes in California.

2017-07-11

Osteonecrosis of the femoral head (ONFH) is a prevalent complication of sickle cell disease (SCD) that has not been well described in population-based cohort studies. Using California's Office of Statewide Planning and Development discharge databases (1991-2013), we estimated the cumulative incidence of ONFH after accounting for the competing risk of death and used a multivariable Cox proportional hazards regression to identify factors associated with ONFH diagnosis. We also calculated rates of readmissions to the hospital or emergency department within 30 to 90 days of hip replacement surgery. Of the 6237 patients in our SCD cohort, 22% (n = 1356) developed ONFH at a median age of 27 years, and 23% (n = 308) of the patients with ONFH underwent hip replacement surgery at a median age of 36 years. The cumulative incidence of ONFH to age 30 years was higher among SCD patients with more severe disease (24%; vs 8% in less severe) and those with antecedent acute chest syndrome (ACS) (18%; vs 8% without prior history of ACS). From 2003 to 2013, SCD patients with more severe disease (hazard ratio [HR], 2.77; 95% confidence interval [CI], 2.38-3.23) or with antecedent ACS (HR, 1.61; CI, 1.35-1.91) were more likely to develop ONFH. Twenty-seven percent of post-hip surgery patients were readmitted within 30 days, mostly for painful vaso-occlusive crises. ONFH is a common SCD complication that increases with age; ongoing studies into prevention and effective nonsurgical interventions for SCD-induced osteonecrosis must remain a high research priority.

Modeling the Effect of Replacing Sugar-Sweetened Beverage Consumption with Water on Energy Intake, HBI Score, and Obesity Prevalence.

Duffey, Kiyah J; Poti, Jennifer

2016-06-28

Sugar-sweetened beverages (SSB) contribute to excessive weight gain through added energy intake. Replacing SSB with water is one strategy that has shown promise in helping lower excessive energy intake. Using nationally representative data from US adults (n = 19,718) from NHANES 2007-2012 we examine the impact of replacing SSB with water on Healthy Beverage Index (HBI) scores and obesity prevalence. Replacing an 8-ounce serving of SSB with water lowered the percent of energy from beverages from 17% to 11% (among those consuming 1 serving SSB/day). Reductions in the percent energy from beverages were observed across all SSB consumption groups (1-2 servings/day and >2 servings/day). Among adults there was a 9% to 21% improvement in HBI score when one serving of water replaced one serving of SSB. Using previously published randomized controlled trials (RCT) and meta-analyses of measured weight loss we also predicted a reduction in the prevalence of obesity (observed: 35.2%; predicted 33.5%-34.9%, p < 0.05) and increase in the prevalence of normal weight (observed: 29.7%; high weight loss: 31.3%, p < 0.05). Our findings provide further epidemiologic evidence that water in the place of SSB can be used as a strategy to limit energy intake and help individuals meet beverage intake recommendations.

The authors aimed to determine the outcome of and factors associated with success and failure of restorations in endodontically treated teeth in patients in practices participating in the Practitioners Engaged in Applied Research and Learning (PEARL) Network. Practitioner-investigators (P-Is) invited the enrollment of all patients seeking care at participating practices who had undergone primary endodontic therapy and restoration in a permanent tooth three to five years earlier. P-Is classified endodontically reated teeth as restorative failures if the restoration was replaced, the restoration needed replacement or the tooth was cracked or fractured. P-Is from 64 practices enrolled in the study 1,298 eligible patients who had endodontically treated teeth that had been restored. The mean (standard deviation) time to follow-up was 3.9 (0.6) years. Of the 1,298 enrolled teeth, P-Is classified 181 (13.9 percent; 95 percent confidence interval [CI], 12.1-15.8 percent) as restorative failures: 44 (3.4 percent) due to cracks or fractures, 57 (4.4 percent) due to replacement of the original restoration for reasons other than fracture and 80 (6.2 percent) due to need for a new restoration. When analyzing the results by means of multivariate logistic regression, the authors found a greater risk of restorative failure to be associated with canines or incisors and premolars (P = .04), intracoronal restorations (P < .01), lack of preoperative proximal contacts (P < .01), presence of periodontal connective-tissue attachment loss (P < .01), younger age (P = .01), Hispanic/Latino ethnicity (P = .04) and endodontic therapy not having been performed by a specialist (P = .04). These results suggest that molars (as opposed to other types of teeth), full-coverage restorations, preoperative proximal contacts, good periodontal health, non-Hispanic/Latino ethnicity, endodontic therapy performed by a specialist and older patient age are associated with restorative success for endodontically treated teeth in general practice. These results contribute to the clinical evidence base to help guide practitioners when planning the restoration of endodontically treated teeth.

To undertake a retrospective, questionnaire review of surgery for heavy snoring, to ascertain patients' perception of the procedure and its effect on their snoring. A specifically designed postal questionnaire was sent to 261 patients who underwent snoring surgery at University Hospital Aintree, Liverpool, UK, between April 1993 and March 2000. One hundred ninety-three patients responded (73.9%), including 151 men and 42 women. Mean age was 49.0 years (range, 24-74 yrs). Twenty-two patients had a uvulopalatopharyngoplasty, 53 a traditional laser palatoplasty and uvulectomy, and 118 an uvulopalatal elevation palatoplasty. There was a 26% patient-reported postoperative infection rate. Morbidity regarding postoperative swallowing, pharyngeal sensation or voice change appeared minimal. Seventy-six percent scored postoperative pain as "moderate" or "severe," irrespective of the operation performed (P = 0.989). Thirty-seven percent of patients perceived an improvement in postoperative sleep quality. Twenty-four percent of patients reported no improvement in snoring after surgery. Forty-three percent reported an initial improvement that was not sustained for 2 years, whereas 34% of patients benefited from an improvement sustained for longer than 2 years, irrespective of the operation performed (P = 0.143). Only 47%, with hindsight, would have undergone surgery. These data highlight that snoring surgery has a high postoperative morbidity rate and a high failure rate. Research endeavors should be directed to the development of a strategy which enables reliable preoperative identification of patients' who enjoy sustained benefit postoperatively.

An evaluation of information on the Internet of a new device: the lumbar artificial disc replacement.

PubMed

Garcia, Ryan M; Messerschmitt, Patrick J; Ahn, Nicholas U

2009-02-01

An analysis of websites, accessible to the public, was conducted pertaining to the lumbar artificial disc replacement. The objective was to investigate the content of information available on the Internet pertaining to the lumbar artificial disc replacement. The Internet is widely used by patients as an educational tool for health care information. Additionally, the Internet is used as a medium for direct-to-consumer marketing. Recent approval of the lumbar artificial disc replacement has led to the emergence of numerous websites offering information about this procedure. It is thought that patients can be influenced by information found on the Internet; therefore, it is imperative that this information be accurate and as complete as possible. Three commonly used search engines were used to locate 105 (35/search engine) websites providing information about the lumbar artificial disc replacement. Each website was evaluated with regard to authorship and content. Fifty-nine percent of the websites reviewed were authorized by a private physician group, 9% by an academic physician group, 6% by industry, 11% were news reports, and 15% were not otherwise categorized. Seventy-two percent offered a mechanism for direct contact and 30% provided clear patient selection criteria. Benefits were expressed in 87% of websites, whereas associated risks were described in 28% or less. European experiences were noted in 53%, whereas only 22% of websites detailed the current US experience. The results of this study demonstrate that much of the content of Internet-derived information pertaining to the lumbar artificial disc replacement is potentially misleading. Until long-term data are available, patients should be cautioned when using the Internet as a source for health care information, particularly with regard to the lumbar artificial disc replacement.

Little is known about diet quality with a reduced-energy, low-fat, partial meal replacement plan, especially in individuals with type 2 diabetes. The Action for Health in Diabetes (Look AHEAD) trial implemented a partial meal replacement plan in the Intensive Lifestyle Intervention. To compare dietary intake and percent meeting fat-related and food group dietary recommendations in Intensive Lifestyle Intervention and Diabetes Support and Education groups at 12 months. A randomized controlled trial comparing Intensive Lifestyle Intervention with Diabetes Support and Education at 0 and 12 months. From 16 US sites, the first 50% of participants (aged 45 to 76 years, overweight or obese, with type 2 diabetes) were invited to complete dietary assessments. Complete 0- and 12-month dietary assessments (collected between 2001 and 2004) were available for 2,397 participants (46.6% of total participants), with 1,186 randomized to Diabetes Support and Education group and 1,211 randomized to Intensive Lifestyle Intervention group. A food frequency questionnaire assessed intake: energy; percent energy from protein, fat, carbohydrate, polyunsaturated fatty acids, and saturated fats; trans-fatty acids; cholesterol; fiber; weekly meal replacements; and daily servings from food groups from the Food Guide Pyramid. Mixed-factor analyses of covariance, using Proc MIXED with a repeated statement, with age, sex, race/ethnicity, education, and income controlled. Unadjusted χ² tests compared percent meeting fat-related and food group recommendations at 12 months. At 12 months, Intensive Lifestyle Intervention participants had a significantly lower fat and cholesterol intake and greater fiber intake than Diabetes Support and Education participants. Intensive Lifestyle Intervention participants consumed more servings per day of fruits; vegetables; and milk, yogurt, and cheese; and fewer servings per day of fats, oils, and sweets than Diabetes Support and Education participants. A greater percentage of Intensive Lifestyle Intervention participants than Diabetes Support and Education participants met fat-related and most food group recommendations. Within Intensive Lifestyle Intervention, a greater percentage of participants consuming two or more meal replacements per day than participants consuming less than one meal replacement per day met most fat-related and food group recommendations. The partial meal replacement plan consumed by Intensive Lifestyle Intervention participants was related to superior diet quality. Copyright © 2015 Academy of Nutrition and Dietetics.

The study aims to define the efficacy of continuous renal replacement therapy in acute metabolic decompensation treatment of maple syrup urine disease (MSUD). All the neonates, infants and children who have had life threatening conditions due to MSUD and were treated with continuous venovenous hemodiafiltration (CVVHDF) were analyzed retrospectively. Fourteen patients underwent 15 sessions of CVVHDF (age range 15 days to 87 months, mean 40.8 ± 31.4 months). One patient required additional CVVHDF 1 week after cessation of CVVHDF. Twenty seven percent (n = 4) of the patients were intubated and mechanically ventilated. Twelve patients responded to treatment and dramatic neurological improvement was observed within 24 h. Two of the 14 patients required 36 h of CVVHDF for neurological improvement. The mean duration of CVVHDF was 20.2 ± 8.6 (9-36) h. The mean leucine level was 1,648 ± 623.8 (714-2,768) μmol/l before and was 256.5 ± 150.6 (117-646) μmol/l at the end of treatment. No mortality was observed. Continuous hemodiafiltration is an effective and safe method in correcting metabolic disturbances in MSUD. © 2016 S. Karger AG, Basel.

There is a paucity of data on Mohs surgery workforce patterns. To identify if gender differences exist in practice patterns of Mohs surgeons, factors that influence these differences, and factors influencing job satisfaction among Mohs surgeons. An electronic survey was distributed to dermatology organizations targeting members of the American College of Mohs Surgery (ACMS), from October 2015 to April 2016. Two hundred twenty-seven ACMS members responded; 37% were women. Twenty-five percent of women and 19% of men work part time. Thirty-seven percent of women practice in academia versus 22% of men. Forty-three percent of women and 23% of men identified children as a factor affecting their ability to work full time. Gender comparisons for current job satisfaction show 57% of men and 35% of women being very satisfied. Supervision/feedback/recognition adds to satisfaction at a higher rate for women (53%) than for men (29%). For both genders combined, work content, patient base, and autonomy had the highest average job satisfaction ratings. Gender differences exist in practice patterns and job satisfaction of Mohs surgeons. This study demonstrates factors that could influence job satisfaction among female Mohs surgeons-knowledge that is important to individuals who lead, mentor, or supervise female Mohs surgeons.

A container for fuel cells is made from an iron aluminide alloy. The container alloy preferably includes from about 13 to about 22 weight percent Al, from about 2 to about 8 weight percent Cr, from about 0.1 to about 4 weight percent M selected from Zr and Hf, from about 0.005 to about 0.5 weight percent B or from about 0.001 to about 1 weight percent C, and the balance Fe and incidental impurities. The iron aluminide container alloy is extremely resistant to corrosion and metal loss when exposed to dual reducing and oxidizing atmospheres at elevated temperatures. The alloy is particularly useful for containment vessels for solid oxide fuel cells, as a replacement for stainless steel alloys which are currently used.

1985-05-01

Conservation mastectomy in combination with radiotherapy is becoming an accepted treatment for early breast cancer. No absolute guidelines exist as to appropriate patient selection or correct surgical technique, but certain unifying trends can be ascertained from the current literature. The purpose of this study was to review the literature and to identify areas of incongruence between present management of patients in British Columbia and suggestions in the current literature. One hundred patients were reviewed. Twenty-six percent of them did not receive preoperative mammograms, and tumor stage was inappropriate in 9 percent. Thirteen percent had excisional biopsies only. A quarter of the patients had tumor resection through unfavorably placed incisions. Eight percent did not have estrogen receptor determination. Thirty-nine percent of the pathology reports made no comment as to adequacy of resection margins. It is hoped that these areas that, with proper attention, can improve cosmetic results and decrease the incidence of local tumor recurrence.

Is Low Fertility a Twenty-First-Century Demographic Crisis?*

Morgan, S. Philip

2010-01-01

Nearly half of the world's population in 2000 lived in countries with fertility rates at or below replacement level, and nearly all countries will reach low fertility levels in the next two decades. Concerns about low fertility, fertility that is well below replacement, are widespread. But there are both persistent rationales for having children and institutional adjustments that can make the widespread intentions for two children attainable, even in increasingly individualistic and egalitarian societies.

1996-01-01

Objective To review the clinical performance of the anatomic medullary locking (AML) femoral stem in total hip arthroplasty. Design A clinical and radiographic review. Setting A tertiary lower limb joint replacement centre. Patients Two hundred and twenty-one patients with noninflammatory gonarthrosis. Interventions Two hundred and twenty-seven primary total hip arthroplasties with the noncemented AML component completed by two surgeons. Main Outcome Measures Independent review by two experienced reviewers of the postoperative Harris hip score, radiographs of component fixation, size and degree of diaphyseal fill. Results Harris hip score was 84 (range from 43 to 98); component fixation showed bone ingrowth in 41%, stable fixation with fibrous ingrowth in 56% and unstable fixation in 3%; severe thigh pain in 4% of cases correlated with unstable fixation, and there was mild thigh pain in 20% of cases. Conclusion The AML femoral stem performs well in replacement arthroplasty compared with other noncemented stems. PMID:8857987

Controversy still exists as to the optimum management of the posterior cruciate ligament (PCL) in total knee arthroplasty. Surgeons can choose to kinematically substitute the PCL with a posterior-stabilized total knee replacement or alternatively to utilize a cruciate-retaining, also known as minimally stabilized, total knee replacement. Proponents of posterior-stabilized total knee replacement propose that the reported lower survivorship in registries when directly compared with minimally stabilized total knee replacement is due to confounders such as selection bias because of the preferential usage of posterior-stabilized total knee replacement in more complex or severe cases. In this study, we aimed to eliminate these possible confounders by performing an instrumental variable analysis based on surgeon preference to choose either posterior-stabilized or minimally stabilized total knee replacement, rather than the actual prosthesis received. Cumulative percent revision, hazard ratio (HR), and revision diagnosis data were obtained from the Australian Orthopaedic Association National Joint Replacement Registry from September 1, 1999, to December 31, 2014, for 2 cohorts of patients, those treated by high-volume surgeons who preferred minimally stabilized replacements and those treated by high-volume surgeons who preferred posterior-stabilized replacements. All patients had a diagnosis of osteoarthritis and underwent fixed-bearing total knee replacement with patellar resurfacing. At 13 years, the cumulative percent revision was 5.0% (95% confidence interval [CI], 4.0% to 6.2%) for the surgeons who preferred the minimally stabilized replacements compared with 6.0% (95% CI, 4.2% to 8.5%) for the surgeons who preferred the posterior-stabilized replacements. The revision risk for the surgeons who preferred posterior-stabilized replacements was significantly higher for all causes (HR = 1.45 [95% CI, 1.30 to 1.63]; p < 0.001), for loosening or lysis (HR = 1.93 [95% CI, 1.58 to 2.37]; p < 0.001), and for infection (HR = 1.51 [95% CI, 1.25 to 1.82]; p < 0.001). This finding was irrespective of patient age and was evident with cemented fixation and with both cross-linked polyethylene and non-cross-linked polyethylene. However, the higher revision risk was only evident in male patients. There was a 45% higher risk of revision for the patients of surgeons who preferred a posterior-stabilized total knee replacement compared with the patients of surgeons who preferred a minimally stabilized total knee replacement.

According to the U.S. Energy Information Administration, HVAC accounts for approximately 38 percent of U.S. commercial buildings' primary energy consumption and a slightly higher percentage of their greenhouse-gas emissions. We have seen incredible gains made with lighting, going from incandescent and T12 fluorescent bulbs to high-efficiency LEDS, but there are even greater advances to be made with HVAC. Gains of 20 percent to 30 percent easily can be made by replacing older degraded equipment with new high-efficiency equipment. Even more savings are possible with an integrated engineering approach yielding optimized system designs combined with highly efficient controls.

Thin-film sulfuric acid anodizing as a replacement for chromic acid anodizing

NASA Technical Reports Server (NTRS)

Kallenborn, K. J.; Emmons, J. R.

1995-01-01

Chromic acid has long been used to produce a thin, corrosion resistant (Type I) coating on aluminum. Following anodizing, the hardware was sealed using a sodium dichromate solution. Sealing closes up pores inherent in the anodized coating, thus improving corrosion resistance. The thinness of the brittle coating is desirable from a fatigue standpoint, and chromium was absorbed by the coating during the sealing process, further improving corrosion resistance. Unfortunately, both chromic acid and sodium dichromate contain carcinogenic hexavalent chromium. Sulfuric acid is being considered as a replacement for chromic acid. Sulfuric acid of 10-20 percent concentration has traditionally been used to produce relatively thick (Types II and III) or abrasion resistant (Type III) coatings. A more dilute, that is five weight percent, sulfuric acid anodizing process, which produces a thinner coating than Type II or III, with nickel acetate as the sealant has been developed. The process was evaluated in regard to corrosion resistance, throwing power, fatigue life, and processing variable sensitivity, and shows promise as a replacement for the chromic acid process.

Charts of 28 hyperthyroid patients over 60 years old were retrospectively analyzed and compared with charts of 14 patients under 30 years old. The mean duration of symptoms prior to diagnosis was 16 months in the elderly and five months in the younger group. Heart rate was substantially lower in the older (107 beats/min) vs younger (117 beats/min) study group. The symptom of weakness or fatigue was more prevalent in the elderly group (94 percent) than in the younger group (57 percent). Cardiac palpitation was more prevalent in the elderly patients whereas insomnia, irritability, dysphagia, hyperphagia, and heat intolerance were more prevalent in the younger patients. Fifty percent of the elderly patients complained of chest pain. Cachexia (62 percent), thin, fine hair (50 percent), and weakness (58 percent) were prominent physical findings in the elderly group. Twenty-six percent of the elderly patients had atrial fibrillation. These findings confirm previous studies that show some differences in presentation of hyperthyroidism in elderly patients when compared with younger patients. The authors recommend that thyroid function tests be obtained for broad indications in the elderly. PMID:6644837

The aim of the present study was to describe the ultrasound (US) findings in patients with rheumatoid arthritis (RA) in clinical remission, and to evaluate the ability of power Doppler (PD) US to reclassify disease activity in these patients. We included consecutive patients with RA according to 2010 American College of Rheumatology/European League Against Rheumatism criteria, who were in clinical remission by the Disease Activity Score (DAS28<2.6). Twenty joints of both hands were assessed by US. PD signal was evaluated on a semi-quantitative scale from 0 to 3. Three different US-modified DAS28 (US-DAS28) were constructed, replacing the clinical swollen joint count by the PD US joint count using PD score ≥1, ≥2 or ≥3, respectively. Eighty-six patients were included. Twenty-three (26.7%) patients had at least one joint with abnormal US-positive PD signal. Thirteen percent of patients were reclassified to low disease activity by applying the US-DAS28 when joints were considered active with a PD signal ≥1; 12%, when a PD signal ≥2 was considered, and 2% of the patients were reclassified when a PD score of 3 was considered. No patients were reclassified to a level of moderate or high activity applying US-DAS28. Although around a quarter of patients with RA in clinical remission showed PD US features indicating residual activity, only a small percentage were reclassified to a state of low activity and none to a level of moderate or high activity, applying the proposed US-DAS28.

It is shown in this paper that the D-He-3 fusion fuel cycle is not only credible from a physics standpoint, but that its breakeven and ignition characteristics could be developed on roughly the same time schedule as the DT cycle. It was also shown that the extremely low fraction of power in neutrons, the lack of significant radioactivity in the reactants, and the potential for very high conversion efficiencies, can result in definite advantages for the D-He-3 cycle with respect to DT fusion and fission reactors in the twenty-first century. More specifically, the D-He-3 cycle can accomplish the following: (1) eliminate the need for deep geologic waste burial facilities and the wastes can qualify for Class A, near-surface land burial; (2) allow 'inherently safe' reactors to be built that, under the worst conceivable accident, cannot cause a civilian fatality or result in a significant (greater than 100 mrem) exposure to a member of the public; (3) reduce the radiation damage levels to a point where no scheduled replacement of reactor structural components is required, i.e., full reactor lifetimes (approximately 30 FPY) can be credibly claimed; (4) increase the reliability and availability of fusion reactors compared to DT systems because of the greatly reduced radioactivity, the low neutron damage, and the elimination of T breeding; and (5) greatly reduce the capital costs of fusion power plants (compared to DT systems) by as much as 50 percent and present the potential for a significant reduction on the COE. The concepts presented in this paper tie together two of the most ambitious high-technology endeavors of the twentieth century: the development of controlled thermonuclear fusion for civilian power applications and the utilization of outer space for the benefit of mankind on Earth.

To compare methods and results among four health technology assessment organizations in different countries. All assessment reports published between 1999 and 2001 by VATAP (United States), NICE (United Kingdom), CCOHTA (Canada), and AETS (Spain), were reviewed. Detailed information about the organization, the technology assessed, the methods used, and the recommendations made were collected. A descriptive analysis of the variables, as well as comparisons of means and proportions, was performed. Sixty-one reports assessing seventy-six technologies were published: nine (11.8 percent) by VATAP, thirty-nine (51.3 percent) by NICE, twenty (26.3 percent) by CCOHTA, and eight (10.5 percent) by AETS. A total of 64.5 percent of the technologies assessed were related to a high prevalence disease in the corresponding country. Most of the assessments addressed treatments (73.7 percent) and were mostly drugs (56.6 percent) and devices (23.7 percent). Most organizations used reviews of effectiveness and economic evaluations (64.5 percent), systematic reviews (21.1 percent), and original economic evaluations (36.7 percent). In 38.1 percent, the technology was recommended; the rest of the cases had no formal recommendations. Critical issues for future technology assessment efforts are making assessment processes more consistent, transparent, and evidence-based; formalizing the inclusion of economic and ethical considerations; and making more explicit the prioritization process for selecting technologies for assessment and reassessment.

The time patients spend in a doctor's waiting room prior to a scheduled appointment is an important component of the quality of the overall health care experience. We analyzed data on twenty-one million outpatient visits obtained from electronic health record systems, which allowed us to measure time spent in the waiting room beyond the scheduled appointment time. Median wait time was a little more than four minutes. Almost one-fifth of visits had waits longer than twenty minutes, and 10 percent were more than thirty minutes. Waits were shorter for early-morning appointments, for younger patients, and at larger practices. Median wait time was 4.1 minutes for privately insured patients and 4.6 minutes for Medicaid patients. After adjustment for patient and appointment characteristics, Medicaid patients were 20 percent more likely than the privately insured patients to wait longer than twenty minutes, with most of this disparity explained by differences in practices and providers they saw. Wait times for Medicaid patients relative to privately insured patients were longer in states with relatively lower Medicaid reimbursement rates. The study complements other work that suggests that Medicaid patients face some additional barriers in the receipt of care. Project HOPE—The People-to-People Health Foundation, Inc.

Abstract Knowing one's HIV status is particularly important in the setting of recent tuberculosis (TB) exposure. Blood tests for assessment of tuberculosis infection, such as the QuantiFERON Gold in-tube test (QFT; Cellestis Limited, Carnegie, Victoria, Australia), offer the possibility of simultaneous screening for TB and HIV with a single blood draw. We performed a cross-sectional analysis of all contacts to a highly infectious TB case in a large meatpacking factory. Twenty-two percent were foreign-born and 73% were black. Contacts were tested with both tuberculin skin testing (TST) and QFT. HIV testing was offered on an opt-out basis. Persons with TST ≥10 mm, positive QFT, and/or positive HIV test were offered latent TB treatment. Three hundred twenty-six contacts were screened: TST results were available for 266 people and an additional 24 reported a prior positive TST for a total of 290 persons with any TST result (89.0%). Adequate QFT specimens were obtained for 312 (95.7%) of persons. Thirty-two persons had QFT results but did not return for TST reading. Twenty-two percent met the criteria for latent TB infection. Eighty–eight percent accepted HIV testing. Two (0.7%) were HIV seropositive; both individuals were already aware of their HIV status, but one had stopped care a year previously. None of the HIV-seropositive persons had latent TB, but all were offered latent TB treatment per standard guidelines. This demonstrates that opt-out HIV testing combined with QFT in a large TB contact investigation was feasible and useful. HIV testing was also widely accepted. Pairing QFT with opt-out HIV testing should be strongly considered when possible. PMID:20731612

The authors conducted a study to determine the types, outcomes, risk factors and esthetic assessment of implants and their restorations placed in the general practices of a practice-based research network. All patients who visited network practices three to five years previously and underwent placement of an implant and restoration within the practice were invited to enroll. Practitioner-investigators (P-Is) recorded the status of the implant and restoration, characteristics of the implant site and restoration, presence of peri-implant pathology and an esthetic assessment by the P-I and patient. The P-Is classified implants as failures if the original implant was missing or had been replaced, the implant was mobile or elicited pain on percussion, there was overt clinical or radiographic evidence of pathology or excessive bone loss (> 0.2 millimeter per year after an initial bone loss of 2 mm). They classified restorations as failures if they had been replaced or if there was abutment or restoration fracture. The authors enrolled 922 implants and patients from 87 practices, with a mean (standard deviation) follow-up of 4.2 (0.6) years. Of the 920 implants for which complete data records were available, 64 (7.0 percent) were classified as failures when excessive bone loss was excluded from the analysis. When excessive bone loss was included, 172 implants (18.7 percent) were classified as failures. According to the results of univariate analysis, a history of severe periodontitis, sites with preexisting inflammation or type IV bone, cases of immediate implant placement and placement in the incisor or canine region were associated with implant failure. According to the results of multivariate analysis, sites with preexisting inflammation (odds ratio [OR] = 2.17; 95 percent confidence interval [CI], 1.41-3.34]) or type IV bone (OR = 1.99; 95 percent CI, 1.12-3.55) were associated with a greater risk of implant failure. Of the 908 surviving implants, 20 (2.2 percent) had restorations replaced or judged as needing to be replaced. The majority of P-Is and patients were satisfied with the esthetic outcomes for both the implant and restoration. These results suggest that implant survival and success rates in general dental practices may be lower than those reported in studies conducted in academic or specialty settings. The results of this study, generated in the private general practice setting, add to the evidence base to facilitate implant treatment planning.

Sheffler, K. D.; Graziani, R. A.; Sinko, G. C.

1982-01-01

The technology of plasma sprayed thermal barrier coatings applied to turbine vane platforms in modern high temperature commercial engines was advanced to the point of demonstrated feasibility for application to commercial aircraft engines. The three thermal barrier coatings refined under this program are zirconia stabilized with twenty-one percent magnesia (21% MSZ), six percent yttria (6% YSZ), and twenty percent yttria (20% YSZ). Improvement in thermal cyclic endurance by a factor of 40 times was demonstrated in rig tests. A cooling system evolved during the program which featured air impingement cooling for the vane platforms rather than film cooling. The impingement cooling system, in combination with the thermal barrier coatings, reduced platform cooling air requirements by 44% relative to the current film cooling system. Improved durability and reduced cooling air requirements were demonstrated in rig and engine endurance tests. Two engine tests were conducted, one of 1000 cycles and the other of 1500 cycles. All three coatings applied to vanes fabricated with the final cooling system configuration completed the final 1500 cycle engine endurance test. Results of this test clearly demonstrated the durability of the 6% YSZ coating which was in very good condition after the test. The 21% MSZ and 20% YSZ coatings had numerous occurrences of significant spalling in the test.

2017-05-01

As Newfoundland has the highest rate of familial colorectal cancer (CRC) in the world, we started a population-based clinic to provide colonoscopic and Lynch syndrome (LS) screening recommendations to families of CRC patients based on family risk. Of 1091 incident patients 51% provided a family history. Seventy-two percent of families were at low or intermediate-low risk of CRC and colonoscopic screening recommendations were provided by letter. Twenty-eight percent were at high and intermediate-high risk and were referred to the genetic counsellor, but only 30% (N = 48) were interviewed by study end. Colonoscopy was recommended more frequently than every 5 years in 35% of families. Lower family risk was associated with older age of proband but the frequency of screening colonoscopy recommendations varied across all age groups, driven by variability in family history. Twenty-four percent had a high MMR predict score for a Lynch syndrome mutation, and 23% fulfilled the Provincial Program criteria for LS screening. A population-based approach in the provision of colonoscopic screening recommendations to families at risk of CRC was limited by the relatively low response rate. A family history first approach to the identification of LS families was inefficient. © 2016 The Authors. Clinical Genetics published by John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The Hidden Side of Zero Tolerance Policies: The African American Perspective

PubMed Central

Bell, Charles

2015-01-01

Several papers have documented the disproportionate representation of African Americans in school discipline and incarceration settings as a result of zero tolerance policies. In 2009, a federal study of the Chicago Public School system found African American boys represented 23 percent of the school age population, 44 percent of students who were suspended, and 61 percent of students who were expelled within the 2007 school year. Twenty years after the implementation of the Anti-Drug Abuse Acts of 1986 and 1988, studies show African Americans comprised a startling 74 percent of those incarcerated for drug offenses despite being only 15 percent of America’s drug users. Despite overwhelming evidence that suggests African Americans are adversely affected by zero tolerance policies, African American perceptions of zero tolerance policies remain relatively hidden in the literature. The current review seeks to explore a seemingly bidirectional process that involves how zero tolerance impacts African Americans and how African Americans perceive zero tolerance policies.

The author has identified the following significant results. Preliminary visual examination of film positives of thirty ERTS-1 scenes obtained over New York State and adjacent areas indicates the following: (1) sixty percent of the imagery has a cloud cover of 70-100 percent, twenty-five percent has a cloud cover of 0-30 percent, and the remainder has a cover of 40-65 percent; (2) on the useable imagery, the spectral lines which may turn out to be geologically-linked totals as follows: spectral linears, 5200 km; broadly curved lines (spectral curvilinears), 700 km; major forest boundaries, 3100 km; areas with spectral geological fabric, 3100 sgkm. In the central and northwest Adirondacks, known lineaments and faults were subtracted from the spectral linears leaving a residue which totals 160 km in the central Adirondacks and 230 km in the northwest Adirondacks. It must be emphasized that these are spectral linears which have not yet been checked out against any ground truth except geological.

Ineffectiveness of commercial weight-loss programs for achieving modest but meaningful weight loss: Systematic review and meta-analysis.

2017-10-01

This study collates existing evidence regarding weight loss among overweight but otherwise healthy adults who use commercial weight-loss programs. Systematic search of 3 databases identified 11 randomized controlled trials and 14 observational studies of commercial meal-replacement, calorie-counting, or pre-packaged meal programs which met inclusion criteria. In meta-analysis using intention-to-treat data, 57 percent of individuals who commenced a commercial weight program lost less than 5 percent of their initial body weight. One in two (49%) studies reported attrition ≥30 percent. A second meta-analysis found that 37 percent of program completers lost less than 5 percent of initial body weight. We conclude that commercial weight-loss programs frequently fail to produce modest but clinically meaningful weight loss with high rates of attrition suggesting that many consumers find dietary changes required by these programs unsustainable.

Dissolved pesticides, dissolved organic carbon, and water-quality characteristics in selected Idaho streams, April--December 2010

2012-01-01

Water-quality samples were collected from April through December 2010 from four streams in Idaho and analyzed for a suite of pesticides, including fungicides, by the U.S. Geological Survey. Water samples were collected from two agricultural and two nonagricultural (control) streams approximately biweekly from the beginning of the growing season (April) through the end of the calendar year (December). Samples were analyzed for 90 pesticides using gas chromatography/mass spectrometry. Twenty-three pesticides, including 8 fungicides, 10 herbicides, 3 insecticides, and 2 pesticide degradates, were detected in 45 water samples. The most frequently detected compounds in the two agricultural streams and their detection frequencies were metolachlor, 96 percent; azoxystrobin, 79 percent; boscalid, 79 percent; atrazine, 46 percent; pendimethalin, 33 percent; and trifluralin, 33 percent. Dissolved-pesticide concentrations ranged from below instrumental limits of detection (0.5-1.0 nanograms per liter) to 771 nanograms per liter (hexazinone). The total number of pesticides detected in any given water sample ranged from 0 to 11. Only three pesticides (atrazine, fipronil, and simazine) were detected in samples from the control streams during the sampling period.

Effect of Rolling Bearing Refurbishment and Restoration on Bearing Life and Reliability

NASA Technical Reports Server (NTRS)

Zaretsky, Erwin V.; Branzai, Emanuel V.

2005-01-01

For nearly four decades it has been a practice in commercial and military aircraft application that rolling-element bearings removed at maintenance or overhaul be reworked and returned to service. The work presented extends previously reported bearing life analysis to consider the depth (Z(45)) to maximum shear stress (45) on stressed volume removal and the effect of replacing the rolling elements with a new set. A simple algebraic relationship was established to determine the L(10) life of bearing races subject to bearing rework. Depending on the extent of rework and based upon theoretical analysis, representative life factors (LF) for bearings subject to rework ranged from 0.87 to 0.99 the lives of new bearings. Based on bearing endurance data, 92 percent of the bearing sets that would be subject to rework would result in L(10) lives equaling and/or exceeding that predicted for new bearings with the remaining 8 percent having the potential to achieve the analytically predicted life of new bearings when one of the rings is replaced at rework.. The potential savings from bearing rework varies from 53 to 82 percent that of new bearings depending on the cost, size and complexity of the bearing.

Diabetes is the seventh leading cause of death in the United States and contributes to long-term complications that are costly to healthcare systems. Twenty-five percent of all veterans in the Veterans Health Administration (VHA) have diabetes. The purpose of this article is to describe the development and implementation of a quality improvement project to embed an evidence-based diabetes screening tool, based on Veterans Affairs/Department of Defense diabetes clinical practice guidelines, into the VHA electronic medical record. The objectives of the screening tool were threefold: to promote evidence-based care, to standardize care coordination, and to promote self-management and proper utilization of resources. Record reviews were conducted to evaluate the effectiveness of the screening tool. Results showed an 88 percent increase in the assessment of annual exams and/or labs, a 16.5 percent increase in disease management assessment and offering of services, and a 50 percent increase in goal-setting activity.

With the current controversy regarding the safety of silicone implants, the detection and evaluation of implant rupture are causing concern for both plastic surgeons and patients. Our study obtained comparative value analysis of mammography, sonography, and magnetic resonance imaging (MRI) in the detection of silicone implant rupture. Twenty-nine symptomatic patients (total of 59 silicone implants) were entered into the study. Intraoperative findings revealed 21 ruptured implants (36 percent). During physical examination, a positive "squeeze test" was highly suggestive of implant rupture. Mammograms were obtained of 51 implants (sensitivity 11 percent, specificity 89 percent). Sonography was performed on 57 implants (sensitivity 70 percent, specificity 92 percent). MRI was performed on 55 implants (sensitivity 81 percent, specificity 92 percent). Sonographically, implant rupture is demonstrated by the "stepladder sign." Double-lumen implants may appear as false-positive results for rupture on sonography. On MRI, the "linguine sign" represents disrupted fragments of a ruptured implant. The most reliable imaging modality for implant rupture detection is MRI, followed by sonogram. Mammogram is the least reliable. Our study supports the clinical indication and diagnostic value of sonogram and MRI in the evaluation of symptomatic breast implant patients.

2007-01-01

The aim of the study is to make an international comparison of Health Technology Assessment (HTA) Agencies, to show their similarities and differences. An e-mail questionnaire was sent to thirty HTA agencies internationally. Questions related to the structure of the agency, the relationship with health-related institutions, the prescriptiveness of the decisions taken, the main core and the modalities to spread the assessment, and the type of funding. Twenty-four HTA Agencies answered the questionnaire: 25 percent in America, 4.2 percent in Australia, and 70.8 percent in Europe. Fifty-four percent of HTA Agencies are governmental institutions (83.3 percent have central government funding), while 62.5 percent have relationships with health-related governmental institutions. Of the agencies, 87 percent reported that their decisions are not prescriptive, while for 20.8 percent and 8.3 percent of them stated that this was the case totally or partially, respectively, especially for the governmental and American Agencies. Seventeen agencies (70.8 percent) declared their work on multiannual programs (77 percent of the governmental HTA Agencies and 100 percent of the American ones). The assessments mainly addressed diagnostic procedures (85.7 percent) and pharmaceuticals (25 percent). The most common way to disseminate results is by means of paper report (91.7 percent), followed by the Internet (16.7 percent), and seminars to expert audiences (12.5 percent). The comparative analysis of HTA Agencies showed that governmental and American Agencies have a profound impact on the prescriptiveness of their assessment, and this could be linked to the fact that these types of Agencies work on multiannual programs. European and American HTA Agencies have many similarities in terms of type of assessment, funding, and dissemination of results.

2015-01-01

The objective of this study was to explore barriers and facilitators influencing the integration of ethical considerations in health technology assessment (HTA). The study consisted of two complementary approaches: (a) a systematic review of the literature; and (b) an eighteen-item online survey that was distributed to fifty-six HTA agencies affiliated with the International Network of Agencies for Health Technology Assessment. The review identified twenty-six relevant articles. The most often cited barriers in the literature were: scarcity, heterogeneity and complexity of ethical analysis methods; challenges in translating ethical analysis results into knowledge that is useful for decision makers; and lack of organizational support in terms of required expertise, time and financial resources. The most frequently cited facilitators included: usage of value-based appraisal methods, stakeholder and public engagement, enhancement of practice guidelines, ethical expertise, and educational interventions. Representatives of twenty-six (46.5 percent) agencies from nineteen countries completed the survey. A median of 10 percent (interquartile range, 5 percent to 50 percent) of the HTA products produced by the agencies was reported to include an assessment of ethical aspects. The most commonly perceived barriers were: limited ethical knowledge and expertise, insufficient time and resources, and difficulties in finding ethical evidence or using ethical guidelines. Educational interventions, demand by policy makers, and involvement of ethicists in HTA were the most commonly perceived facilitators. Our results emphasize the importance of simplification of ethics methodology and development of good practice guidelines in HTA, as well as capacity building for engaging HTA practitioners in ethical analyses.

Gestational diabetes mellitus (GDM) is common and is accompanied with other comorbidities. Challenges to treatment exist at our institute as it serves women with low income. This study assessed the burden of comorbidities and the outcome of GDM. This was a prospective, observational study of women with gestational diabetes attending the obstetrics department from September 2012 to April 2014. GDM was diagnosed based on the International Association of Diabetes and Pregnancy Study Groups criteria. Medical comorbidities were noted, and lipid profile was done. All the women were followed up till delivery, and the complications were recorded. Age- and parity-matched pregnant women with normal oral glucose tolerance test were recruited as controls. One hundred and thirty-nine women were followed up till delivery. The average age was 28 years. Eighteen percent had bad obstetric history. The average body mass index was 28.8. Twenty-five percent had gestational hypertension (HTN), and 6.4% had chronic HTN. Thirty percent had hypothyroidism. 65% women received insulin. The glucose values were within the recommended range in 60% of the women. Maternal hypoglycemia occurred in 7 (5%) women. Forty-four percent of the women required cesarean section and 34% had complications either during pregnancy or labor. Three neonates had macrosomia. Twenty-six neonates (20%) required admission to the Neonatal Intensive Care Unit. Four neonates (3%) died. Newborns of mothers whose GDM optimally treated had less complications. Gestational diabetes is associated with HTN, hypothyroidism, obesity, and lipid abnormalities. The majority of women required insulin for treatment and optimal control of blood glucose resulted in lower neonatal complications.

Design and testing of microfabricated surgical tools for large animal probe insertion

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jorgensen, Shelly

Neural probes provide therapeutic stimulation for neuropsychiatric disorders or record neural activity to investigate the workings of the brain. Researchers utilize 6 mm long temporary silicon stiffeners attached with biodissolvable adhesive to insert flexible neural probes into rat brains, but increasing the probe length fivefold makes inserting large animal probes a significant challenge because of an increased potential for buckling. This study compared the insertion success rates of 6 mm and 30 mm long silicon stiffeners that were 80 μm wide and 30 μm thick, and ascertained the material thickness and modulus of elasticity that would provide successful insertion formore » a 30 mm probe. Using a microdrive, stiffeners were inserted into an agarose brain phantom at controlled insertion speeds while being video-recorded. Twenty-five percent of the 30 mm silicon stiffeners fully inserted at speeds approximately four times higher than the target rate of 0.13 mm/s, while 100 percent of the 6 mm silicon stiffeners inserted successfully at target speed. Critical buckling loads (P cr) were calculated for the 6 mm and 30 mm silicon stiffeners, and for 30 mm diamond and tungsten stiffeners, with thicknesses varying from 30-80 μm. Increasing the thickness of the material by 10 μm, 20 μm and 30 μm improved the P cr by 2.4, 4.7 and 8.2 times, respectively, independent of the material, and substituting diamond for silicon multiplied the buckling capacity by 5.0 times. Stiffeners made of silicon for large animal probe insertion are not strong enough to withstand buckling upon insertion without a significant increase in thickness. Replacing silicon with diamond and increasing the thickness of the stiffener to 50 μm would afford a stiffener with the same P cr capacity as the 6 mm silicon stiffener that had a 100 percent insertion success rate. Experiments should continue with diamond to determine a minimum thickness that will ensure successful insertions and provide an adequate margin of safety.« less

The fear of using tramadol for pain control (tramadolophobia) by Egyptian patients with cancer is a frequent problem in our practice. This study was conducted to explore the prevalence of and the reasons behind tramadolophobia among Egyptian patients with cancer. A structured interview including open-ended and closed questions. The study included 178 adult patients with cancer from two cancer centers in Cairo and Sharkia, Egypt. The source of information about tramadol was a non-healthcare-related source in 168 (94 percent) patients, mainly the media (50 percent). The believed uses of tramadol were abuse related in 94 (53 percent) patients, stimulant (physical, sexual, and to boost alertness) in 59 (33 percent), and analgesic in 55 (31 percent). Twenty-six (15 percent) patients gave history of tramadol use, largely (69 percent) as a stimulant. In case tramadol was prescribed for pain control, 90 (51 percent) patients refused to take it, 59 (33 percent) patients agreed to take it with concern about addiction, and only 29 (16 percent) patients agreed without concerns. Among those who refused taking tramadol for pain, the mentioned reason of refusal was addiction-related fears in 57 percent. The stigmatization and misconceptions about tramadol may have resulted in tramadolophobia among the majority of Egyptian patients with cancer. This further complicates the barriers to cancer pain control in Egypt. Being the only available World Health Organization step-II analgesic in Egypt, interventions to overcome tramadolophobia should be taken.

1975-11-01

From March 1971 through April 1975, one hundred twenty patients underwent mitral valve replacement with a Hancock "stabilized glutaraldehyde process" porcine aortic xenograft. A simultaneous canine experimental series was also carried out. In the clinical series, the early mortality was 8.3%. Actuarial analyses of all patients predicts survival at two years of 81.0% and at four years of 70.0%. The predicted survival for patients without coronary disease or prior prosthetic valve replacement is 87.5% at two years and 77.5% at four years. There were four thromboembolic episodes, a rate of 2.4% per patient-year. None were fatal. No valve failure were noted. Histologic examination and shrink temperature analysis of recovered valves show excellent tissue preservation at 40 months. The data indicate that the Hancock valve is durable, enjoys a low incidence of thromboembolism, and may be the valve of choice for mitral valve replacement.

Humpherys, Mark A.

1994-01-01

Kirkhill Rubber Company (KRC) has informed Thiokol Corporation that two raw materials used in the asbestos and silica filled acrylonitrile butadience rubber (NBR) formulation per STW 2621 are no longer available from their vendors. Agerite White (Di-beta-naphthyl-paraphenylene diamine), manufactured by B. F. Goodrich, is an antioxidant used in NBR. This raw material makes up roughly 1-2 percent of the finished product. KRC proposed that this raw material be replaced by Agerite Stalite S (mixture of octylated diphenylamines) distributed by R. T. Vanderbilt Co. Protox-166 zinc oxide, manufactured by Zinc Corporation of America, is an activator currently used in NBR. This material also makes up about 1-2 percent of the finished material. Protox-166 is an American process grade zinc oxide. It is proposed by KRC to replace Protox-166 with Kadox-930C, a French process grade zinc oxide. American process grades have an ASTM minimum purity of 99.0 percent; the French process grades have a minimum purity of 99.5 percent. Previous testing per WTP-0270 has demonstrated that the mechanical and thermal properties of the rubber with the new ingredients are comparable to the 'old' rubber. The test results are reported in TWR-61790. One igniter adapter, Part no. 7U77562-02 serial no. 2 was insulated per ETP-1206 using the new rubber formulation and a modified lay up and cure method to demonstrate that there is no impact on this process. The results of this demonstration are reported.

Earth Exploration Toolbook Workshops: Web-Conferencing and Teleconferencing Professional Development Bringing Earth Science Data Analysis and Visualization Tools to K-12 Teachers and Students

NASA Astrophysics Data System (ADS)

McAuliffe, C.; Ledley, T.

2008-12-01

The Earth Exploration Toolbook (EET) Workshops Project provides a mechanism for teachers and students to have successful data-using educational experiences. In this professional development project, teachers learn to use National Science Digital Library (NSDL), the Digital Library for Earth System Education (DLESE), and an Earth Exploration Toolbook (EET) chapter. In an EET Data Analysis Workshop, participants walk through an Earth Exploration Toolbook (EET) chapter, learning basic data analysis techniques and discussing ways to use Earth science datasets and analysis tools with their students. We have offered twenty-eight Data Analysis Workshops since the project began. The total number of participants in the twenty-eight workshops to date is three hundred eleven, which reflects one hundred eighty different teachers participating in one or more workshops. Our workshops reach middle and high school teachers across the United States at schools with lower socioeconomic levels and at schools with large numbers of minority students. Our participants come from thirty-eight different states including Alaska, Maine, Florida, Montana, and many others. Eighty-six percent of our participants are classroom teachers. The remaining fourteen percent are staff development specialists, university faculty, or outreach educators working with teachers. Of the classroom teachers, one third are middle school teachers (grades 6 to 8) and two thirds are high school teachers (grades 9 to 12.) Thirty-four percent of our participants come from schools where minority populations are the majority make up of the school. Twenty-five percent of our participants are at schools where the majority of the students receive free or reduced cost lunches. Our professional development workshops are helping to raise teachers' awareness of both the Digital Library for Earth System Education (DLESE) and the National Science Digital Library (NSDL). Prior to taking one of our workshops, forty-two percent of our participants reported that they have not tried to locate a teaching resource in DLESE and forty-eight percent report that they have not to locate a teaching resource in NSDL. As part of an EET Data Analysis workshop, teachers actively visit both digital libraries. Virtual workshops using Web conferencing and teleconferencing are an effective and convenient way to deliver professional development that brings teachers from all over the nation together to learn new technology. Teachers report that the step-by-step facilitation along with the ability to ask questions and interact with their peers are some of the most useful aspects of the workshop. In this presentation, we will share successes and challenges of teachers as they implement these Earth science data analysis and visualization tools in their classrooms.

Retention of mercury in the muscle of yellow perch (Perca flavescens) and rock bass (Ambloplites rupestris)

Mercury-contaminated yellow perch (Perca flavescens) and rock bass (Ambloplites rupestris) were collected from Lake St. Clair and stocked in two earthern ponds in September 1970. Twenty-six months later, concentrations of total mercury in the fillets had declined 53 percent in the yellow perch and 59 percent in the rock bass; however, the mean weight of the fish increased 88 and 183 percent, respectively, during the same period. All of the reduction in mercury concentrations was attributable to dilution by growth. Slight discrepancies between the theoretical and observed reduction of mercury concentrations suggest an initial redistribution of residues from other tissuesmore » to the muscle and a continued incorporation of background amounts of mercury during growth.« less

Levels and sources of fat in the U.S. food supply.

Raper, N R; Marston, R M

1986-01-01

The amount of fat in the U.S. food supply increased one-third between 1909-13 and 1984, from 124 grams to 166 grams per capita per day. Also, the proportion of food energy provided by fat increased from 32 to 43 percent. The gain in fat in the food supply was due to an increase in fat from vegetable sources. The share of fat from vegetable sources increased from 17 to 42 percent between 1909-13 and 1984. Although animal fats provided the largest share of fat, their proportionate contribution declined from 83 to 58 percent between 1909-13 and 1984. Three food groups--fats and oils; meat, poultry, and fish; and dairy products--provided about 90 percent of the fat in the food supply throughout the past 75 years. However, the shares of fat provided by these groups changed. The share from the fats and oils group increased from 37 to 44 percent between 1909-13 and 1984, while the share from the meat, poultry, and fish group declined from 37 to 34 percent, and the share from the dairy products group declined from 15 to 12 percent. Fat from the fats and oils group increased 59 percent between 1909-13 and 1984. Most of the gain in fat from this group was due to increased use of edible oils. Margarine replaced much of the butter and shortening replaced much of the lard as sources of fat. Fat from the meat, poultry, and fish group increased 24 percent between 1909-13 and 1984. Pork accounted for the largest proportion of fat from this group and beef ranked second. The share of fat from poultry, although much smaller than either pork or beef, almost tripled. Fat from dairy products was about the same in 1984 as in 1909-13. Cheese was the leading source of fat from dairy products by 1984. Until recent years, whole milk was the leading source, although its share declined substantially after the late 1950's. Despite their low fat content, the share of fat from skim and lowfat milks increased as use increased, particularly in the past 25 years. The proportion of fat provided by frozen desserts increased over the years, while that from creams decreased. Among the fatty acids in the food supply, the quantity of TSFA increased by 10 percent between 1909-13 and 1984. Quantities of oleic and linoleic acid increased by 39 and 189 percent, respectively, between 1909-13 and 1984.(ABSTRACT TRUNCATED AT 400 WORDS)

HIV/AIDS is highly prevalent in sub-Saharan Africa and few studies had looked at physically and mentally challenged people living with HIV/AIDS (PLHIV) in this environment. This study aimed to describe the socio-demographic characteristics and challenges faced by these patients attending University College Hospital, Ibadan. A descriptive cross-sectional study design was done. A semi-structured interviewer administered questionnaire was administered to consecutive disabled PLHIV over a period of six months. Data obtained were analyzed using descriptive and inferential statistics. A total of ninety-nine patients were seen during the study period. The mean age of these patients was 39.9 +/- 9.4 years (range 23-60 years). There were 30 (30.3%) males and 69 (69.7%) females. Twenty-four percent had no formal education while 12% had tertiary education. All respondents had suffered stigmatization/discrimination while most were poor. Eighty-seven percent had AIDS at presentation. Musculoskeletal impairments (46.5%), hearing loss (16.2%) and visual impairment (31.3%) were the commonest disability. Over twenty-three percent had prior history of road traffic accident as the cause of disability. Physically and mentally challenged people living with HIV/AIDS are poor and highly stigmatized. They require special assistance to cope and need economic empowerment to reduce their poverty level.

Comparing The Effects Of Reference Pricing And Centers-Of-Excellence Approaches To Value-Based Benefit Design.

PubMed

Zhang, Hui; Cowling, David W; Facer, Matthew

2017-12-01

Various health insurance benefit designs based on value-based purchasing have been promoted to steer patients to high-value providers, but little is known about the designs' relative effectiveness and underlying mechanisms. We compared the impact of two designs implemented by the California Public Employees' Retirement System on inpatient hospital total hip or knee replacement: a reference-based pricing design for preferred provider organizations (PPOs) and a centers-of-excellence design for health maintenance organizations (HMOs). Payment and utilization data for the procedures in the period 2008-13 were evaluated using pre-post and quasi-experimental designs at the system and health plan levels, adjusting for demographic characteristics, case-mix, and other confounders. We found that both designs prompted higher use of designated low-price high-quality facilities and reduced average replacement expenses per member at the plan and system levels. However, the designs used different routes: The reference-based pricing design reduced average replacement payments per case in PPOs by 26.7 percent in the first year, compared to HMOs, but did not lower PPO members' utilization rates. In contrast, the centers-of-excellence design lowered HMO members' utilization rates by 29.2 percent in the first year, compared to PPOs, but did not reduce HMO average replacement payments per case. The reference-based pricing design appears more suitable for reducing price variation, and the centers-of-excellence design for addressing variation in use.

2015-05-01

Partial or complete replacement of fish meal (FM) with fermented soybean meal (FSM) was examined in Macrobrachium nipponense over an 8-week growth trial. Growth and immune characteristics were evaluated. Fermented soybean meal replaced 0 (FM, control), 25% (R25), 50% (R50), 75% (R75), or 100% of the FM (R100) in five isocaloric and isonitrogenous diets. Each diet was fed to juvenile prawns (mean weight, 0.103 ± 0.0009 g) twice daily to apparent satiation in five replicates. Weight gain and specific growth rate of M. nipponense were significantly higher in prawns fed the R25 diet than that of prawns fed the FM diet. No significant differences were observed among the other treatments. Total hemocyte count and hemolymph phagocytic activity decreased as the proportion of FSM increased. Total antioxidant activity competence and malondialdehyde level in the hepatopancreas were highest in prawns fed the R100 diet. mRNA levels of the antioxidant genes Cu-Zn superoxide dismutase and catalase, heat shock cognate protein 70, and heat shock protein 90 were significantly differentially regulated in the prawn hepatopancreas. In addition, percent mortality increased after challenge with live Aeromonas hydrophila. Percent mortality of prawns fed the R100 diet was significantly higher than that of prawns fed the FM and R25 diets. These findings demonstrate that (1) M. nipponense growth performance was not affected by including a high proportion of FSM in the diet, and the best growth performance was obtained when 25% of the FM was replaced with FSM; (2) nonspecific immunity was impaired when all of the FM was replaced with FSM.

2011-09-01

The purpose of this study was to survey the directors of postdoctoral endodontic programs in the United States to ascertain their attitudes and approaches regarding incorporation of implants into the endodontic curriculum. We hypothesized that program directors would agree that implant training should be incorporated into the endodontic curriculum. We also hypothesized that they would all prefer apical surgeries and retreatment over implants when plausible. A twenty-item online survey was emailed to all fifty-two postdoctoral endodontic program directors in the United States. A 100 percent response was received. The results showed that 78.6 percent agreed that implant training should be incorporated, 85.7 percent preferred the didactic approach, and 42.9 percent preferred clinical implant training. One hundred percent preferred apical surgeries and retreatment over implants when plausible, and 53.8 percent did not prefer implants over endodontic treatment for teeth with a questionable prognosis. This survey indicates that implant training has been incorporated into postdoctoral endodontic programs and that the Commission on Dental Accreditation standards are being met. The trend may be to become more hands-on in the future if program directors believe there is a need to provide training in actual placement of implants.

ACA dependent coverage provision reduced high out-of-pocket health care spending for young adults.

PubMed

Busch, Susan H; Golberstein, Ezra; Meara, Ellen

2014-08-01

Since September 2010 the Affordable Care Act (ACA) has required that insurers allow children to remain as dependents on their parents' private insurance plans until age twenty-six. Studies have shown that this provision increased coverage rates among young adults. In this article we analyze whether the provision also protected young adults from large and uncertain out-of-pocket expenses. We found that the policy was associated with a statistically significant reduction in the share of young adults facing annual out-of-pocket expenditures greater than $1,500 (decreasing from 4.2 percent to 2.9 percent), compared to an increase in the proportion of their slightly older peers facing such expenditures (increasing from 4.4 percent to 5.4 percent), a net difference of -2.4 percentage points, or 57 percent. We conclude that the dependent coverage provision in the ACA provides financial protection for young adults at a time when they often face high debt burden but low wages.

An evaluation of information on the internet about a new device: the cervical artificial disc replacement.

PubMed

Qureshi, Sheeraz A; Koehler, Steven M; Lin, James D; Bird, Justin; Garcia, Ryan M; Hecht, Andrew C

2012-05-01

Cross-sectional survey. The objective of this study was to investigate the authorship, content, and quality of information available to the public on the Internet pertaining to the cervical artificial disc replacement device. The Internet is widely used by patients as an educational tool for health care information. In addition, the Internet is used as a medium for direct-to-consumer marketing. Increasing interest in cervical artificial disc replacement has led to the emergence of numerous Web sites offering information about this procedure. It is thought that patients can be influenced by information found on the Internet. A cross section of Web sites accessible to the general public was surveyed. Three commonly used search engines were used to locate 150 (50/search engine) Web sites providing information about the cervical artificial disc replacement. Each Web site was evaluated with regard to authorship and content. Fifty-three percent of the Web sites reviewed were authorized by a private physician group, 4% by an academic physician group, 13% by industry, 16% were news reports, and 14% were not otherwise categorized. Sixty-five percent of Web sites offered a mechanism for direct contact and 19% provided clear patient eligibility criteria. Benefits were expressed in 80% of Web sites, whereas associated risks were described in 35% or less. European experiences were noted in 17% of Web sites, whereas only 9% of Web sites detailed the current US experience. CONCLUSION.: The results of this study demonstrate that much of the content of the Internet-derived information pertaining to the cervical artificial disc replacement is for marketing purposes and may not represent unbiased information. Until we can confirm the content on a Web site to be accurate, patients should be cautioned when using the Internet as a source for health care information related to cervical disc replacement.

The twenty states that make up the U.S. North are bounded by Maine, Maryland, Missouri, and Minnesota. Compared to the rest of the country, the North has a higher population density, relatively little public forest land, and many private forest owners with small forest tracts. Fifty-five percent of northern forest land belongs to nearly 5 million family forest owners....

Miliaria rubra of the lower limbs in underground miners.

PubMed

Donoghue, A M; Sinclair, M J

2000-08-01

This report documents a case series of miliaria rubra of the lower limbs in miners at a deep underground metalliferous mine in tropical arid Australia. During the summer months of February and March 1999, all cases of miliaria rubra of the lower limbs in underground miners seen at the mine's medical centre were clinically examined and administered a questionnaire. Twenty-five patients were seen, an incidence of 56.4 cases per million man-hours. Miliaria rubra was most often located between the ankle and knee (88% of cases). Twenty-four percent had concurrent folliculitis and 20% had concurrent tinea. Thirty-two percent had a personal history of asthma. Walking through ground-water and splashing of the legs was common. Three to 4 weeks of sedentary duties in air conditioning was generally required to achieve resolution of miliaria rubra. The incidence of miliaria rubra of the lower limbs is 38% of the incidence of heat exhaustion at the same mine. The length of disablement is greater, however. Atopics may be at increased risk of miliaria rubra. Control measures are discussed.

Since the year 2000, the number of rapes in Costa Rica has increased at a rate of 42 cases per year. In 2011, 1786 rape cases were reported to the prosecution offices throughout the country, but only 1081 reports continued through the investigation process by the Judicial Investigation Agency. A randomly collected sample of 272 reports received by Judicial Investigation Agency, between July 2012 and June 2013, were prospectively studied. The analysis was limited to cases reported within 30 days following the rape. Results indicate that most of the provinces in the country show an incidence of about 38 cases/100,000 inhabitants. Ninety-six percent of the victims were women, 50% of which were between 10 and 19 years old. More than 99.5% of violators were men. The rape was perpetrated by a single aggressor in 85% of the cases. It was found that 48% of the victims were within the first 11 days of their menstrual cycle at the time of the attack. Twenty-nine percent of rapes occurred in "high rape-risk" circumstances--e.g., victims attacked by strangers in public outdoors or indoors. Twenty-five percent of rapes occur in "moderate rape-risk" circumstances--e.g., victims attacked indoors at public locations or at the home other than the victim's by relatives, sentimental partners or acquaintances. Fifteen percent of rapes occurred in "low rape-risk" circumstances--e.g., victims attacked in their homes by relatives or sentimental partners. In 67% of the cases the perpetrator was an acquaintance of the victim. Eleven percent of the cases corresponded to rapes in which the perpetrator was a partner or ex-partner of the victim. Fourteen percent and 25% of rapes could be classified as "proactive drug-facilitated rapes" or "opportunistic drug-facilitated rapes", respectively. Semen in the vaginal fluid of victims and the genetic profile of the alleged perpetrator were detected in 55% and 33% of the cases, respectively. Copyright © 2014 Elsevier Ireland Ltd.

Finger, G.C.; Starr, L.D.; Dickerson, D.R.; Gutowsky, H.S.; Hamer, J.

1963-01-01

The ??-halogenated pyridines react with potassium fluoride in various solvents to give replacement of the ??-halogen by fluorine. A 50% yield of 2-fluoropyridine was obtained from 2-chloropyridine by heating with potassium fluoride in dimethyl sulfone or tetramethylene sulfone for twenty-one days; 2-bromopyridine gave a similar yield with a heating period of only seven days. The ??-halogens of the polyhalopyridines undergo the exchange reaction more readily than do the halogens of the ??-monohalopyridines. The proposed structures of the fluoropyridines are supported by alternate syntheses and by n.m.r. studies.

MMIC Replacement for Gunn Diode Oscillators

NASA Technical Reports Server (NTRS)

Crowe, Thomas W.; Porterfield, David

2011-01-01

An all-solid-state replacement for high-frequency Gunn diode oscillators (GDOs) has been proposed for use in NASA s millimeter- and submillimeter-wave sensing instruments. Highly developed microwave oscillators are used to achieve a low-noise and highly stable reference signal in the 10-40-GHz band. Compact amplifiers and high-power frequency multipliers extend the signal to the 100-500-GHz band with minimal added phase noise and output power sufficient for NASA missions. This technology can achieve improved output power and frequency agility, while maintaining phase noise and stability comparable to other GDOs. Additional developments of the technology include: a frequency quadrupler to 145 GHz with 18 percent efficiency and 15 percent fixed tuned bandwidth; frequency doublers featuring 124, 240, and 480 GHz; an integrated 874-GHz subharmonic mixer with a mixer noise temperature of 3,000 K DSB (double sideband) and mixer conversion loss of 11.8 dB DSB; a high-efficiency frequency tripler design with peak output power of 23 mW and 14 mW, and efficiency of 16 and 13 percent, respectively; millimeter-wave integrated circuit (MMIC) power amplifiers to the 30-40 GHz band with high DC power efficiency; and an 874-GHz radiometer suitable for airborne observation with state-of-the-art sensitivity at room temperature and less than 5 W of total power consumption.

Opportunities exist to promote minimally invasive dentistry by repairing rather than replacing defective and failing direct resin-based composite restorations. The authors conducted a study to investigate the current teaching of such techniques in U.S. and Canadian dental schools. In late 2010, the authors, with the assistance of the Consortium of Operative Dentistry Educators, invited 67 U.S. and Canadian dental schools to participate in an Internet-based survey. The response rate was 72 percent. Eighty-eight percent of the dental schools taught repair of defective direct resin-based composite restorations. Of these schools, 79 percent reported providing both didactic and clinical teaching. Although teaching repair of defective resin-based composite restorations was included in the didactic curricula of most schools, students in some schools did not gain experience in minimally invasive management of defective resin-based composite restorations by means of performing repair procedures. The American Dental Association's Code on Dental Procedures and Nomenclature does not have a procedure code for resin-based composite restoration repairs, which may limit patients' access to this dental treatment. Teaching dental students minimally invasive dentistry procedures, including restoration repair, extends the longevity of dental restorations and reduces detrimental effects on teeth induced by invasive procedures, thereby serving the interests of patients.

Barker, R.A.; Bush, P.W.; Baker, E.T.

1994-01-01

Because the diagenetic effects of cementation, recrystallization, and mineral replacement diminish the hydraulic conductivity of most rocks composing the Trinity and Edwards-Trinity aquifers, transmissivity values average less than 10,000 feet squared per day over more than 90 percent of the study area. However, the effects of tectonic fractures and dissolution in the Balcones fault zone cause transmissivity values to average about 750,000 feet squared per day in the Edwards aquifer, which occupies less than 10 percent of the study area.

We describe reproductive health issues among pregnant women in a rural area of Kenya with a high coverage of insecticide treated nets (ITNs) and high prevalence of HIV (15%). We conducted a community-based cross-sectional survey among rural pregnant women in western Kenya. A medical, obstetric and reproductive history was obtained. Blood was obtained for a malaria smear and haemoglobin level, and stool was examined for geohelminths. Height and weight were measured. Of 673 participants, 87% were multigravidae and 50% were in their third trimester; 41% had started antenatal clinic visits at the time of interview and 69% reported ITN-use. Malaria parasitemia and anaemia (haemoglobin < 11 g/dl) were detected among 36% and 53% of the women, respectively. Geohelminth infections were detected among 76% of the 390 women who gave a stool sample. Twenty percent of women were underweight, and sixteen percent reported symptoms of herpes zoster or oral thrush in the last two months. Nineteen percent of all women reported using a contraceptive method to delay or prevent pregnancy before the current pregnancy (injection 10%, pill 8%, condom 0.4%). Twenty-three percent of multigravidae conceived their current pregnancy within a year of the previous pregnancy. More than half of the multigravidae (55%) had ever lost a live born child and 21% had lost their last singleton live born child at the time of interview. In this rural area with a high HIV prevalence, the reported use of condoms before pregnancy was extremely low. Pregnancy health was not optimal with a high prevalence of malaria, geohelminth infections, anaemia and underweight. Chances of losing a child after birth were high. Multiple interventions are needed to improve reproductive health in this area.

Objective To determine the prevalence of the 3 components of the female athlete triad [disordered eating, menstrual dysfunction, low bone mineral density (BMD)] and their relationships with brachial artery flow-mediated dilation in professional dancers. Design Prospective study. Setting Academic institution in the Midwest. Participants Twenty-two professional ballet dancers volunteered for this study. Interventions The prevalence of the female athlete triad and its relationship to endothelial dysfunction. Main Outcome Measures Subjects completed questionnaires to assess disordered eating and menstrual status/history. They also completed a 3-day food record and wore an accelerometer for 3 days to determine energy availability. Serum baseline thyrotropin, prolactin, and hormonal concentrations were obtained. Bone mineral density and body composition were measured with a GE Lunar Prodigy dual-energy X-ray absorptiometry. Endothelial function was determined as flow-mediated vasodilation measured by high-frequency ultrasound in the brachial artery. An increase in brachial diameter <5% to hyperemic flow stimulus was defined a priori as endothelial dysfunction. Results Seventeen dancers (77%) had evidence of low/negative energy availability. Thirty-two percent had disordered eating (EDE-Q score). Thirty-six percent had menstrual dysfunction and 14% were currently using hormone contraception. Twenty-three percent had evidence of low bone density (Z-score < −1.0). Sixty-four percent had abnormal brachial artery flow-mediated dilation (<5%). Flow-mediated dilation values were significantly correlated with serum estrogen and whole-body and lumbar BMD. All the 3 components of the triad plus endothelial dysfunction were present in 14% of the subjects. Conclusions Endothelial dysfunction was correlated with reduced BMD, menstrual dysfunction, and low serum estrogen. These findings may have profound implications for cardiovascular and bone health in professional women dancers. PMID:21358502

This study assessed public awareness of warning symptoms, risk factors, and treatment of stroke in Ludhiana, Punjab, North West India. A hospital-based survey was conducted between February 2002 and September 2002 by the Stroke section of Christian Medical College. The study subjects were relatives of patients without history of stroke, attending the outpatient department of the hospital. Trained medical students, interns, and a nurse interviewed subjects using a structured, pretested, open-ended questionnaire. Nine hundred forty-two individuals were interviewed during the study period (56.4% men, mean age 40.1 years, age range 15 to 80 years). Forty-five percent of the subjects did not recognize the brain as the affected organ in stroke. In the multivariate analysis, higher education (P<0.001; odds ratio 2.6; 95%, CI 1.8 to 3.8) and upper socioeconomic status (P<0.005; odds ratio 1.6; CI, 1.1 to 2.2) correlated with a better knowledge of which organ was affected in stroke. Twenty-three percent of the participants did not know a single warning symptom of stroke. Twenty-one percent of the subjects could not identify even a single risk factor for stroke. Seven percent of the study population believed that oil massage would improve stroke victims. A small proportion of subjects believed in witchcraft, faith healing, homeopathic, and ayurvedic treatment (3%). This hospital-based survey reveals a better awareness of stroke warning signs and risk factors. However, knowledge regarding the organ involved, etiology, and treatment of stroke is lacking. Considerable education is needed to increase public awareness in modern concepts of stroke treatment.

2013-01-01

Abdominal wall reconstruction with bioprosthetic mesh is associated with lower rates of mesh infection, fistula formation, and mesh explantation than reconstruction with synthetic mesh. The authors directly compared commonly used bioprosthetic meshes in terms of clinical outcomes and complications. A database of consecutive patients who underwent abdominal wall reconstruction with porcine or bovine acellular dermal matrix and midline musculofascial closure at their institution between January of 2008 and March of 2011 was reviewed. Surgical outcomes were compared. One hundred twenty patients were identified who underwent a nonbridged, inlay abdominal wall reconstruction with porcine [69 patients (57.5 percent)] or bovine acellular dermal matrix (51 patients (42.5 percent)]. The mean follow-up time was 21.0 ± 9.9 months. The overall complication rate was 36.6 percent; the porcine matrix group had a significantly higher complication rate (44.9 percent) than the bovine matrix group (25.5 percent; p = 0.04) and statistically equivalent surgical complications (29.2 percent versus 21.6 percent; p = 0.34). There were no significant differences in rates of recurrent hernia (2.9 percent versus 3.9 percent; p = 0.99) or bulge (7.2 percent versus 0 percent; p = 0.07). However, the rate of intraoperative adverse events in the porcine matrix group [seven events (10.1 percent)] was significantly higher than that in the bovine matrix group (0 percent; p = 0.02). In patients who undergo complex abdominal wall reconstruction, both bovine and porcine acellular dermal matrix are associated with similar rates of postoperative surgical complications and appear to result in similar outcomes. Porcine acellular dermal matrix may be prone to intraoperative device failure. Therapeutic, III.

Small studies show that many children born as extremely preterm infants have neurologic and developmental disabilities. We evaluated all children who were born at 25 or fewer completed weeks of gestation in the United Kingdom and Ireland from March through December 1995 at the time when they reached a median age of 30 months. Each child underwent a formal assessment by an independent examiner. Development was evaluated with use of the Bayley Scales of Infant Development, and neurologic function was assessed by a standardized examination. Disability and severe disability were defined by predetermined criteria. At a median age of 30 months, corrected for gestational age, 283 (92 percent) of the 308 surviving children were formally assessed. The mean (+/-SD) scores on the Bayley Mental and Psychomotor Developmental Indexes, referenced to a population mean of 100, were 84+/-12 and 87+/-13, respectively. Fifty-three children (19 percent) had severely delayed development (with scores more than 3 SD below the mean), and a further 32 children (11 percent) had scores from 2 SD to 3 SD below the mean. Twenty-eight children (10 percent) had severe neuromotor disability, 7 (2 percent) were blind or perceived light only, and 8 (3 percent) had hearing loss that was uncorrectable or required aids. Overall, 138 children had disability (49 percent; 95 percent confidence interval, 43 to 55 percent), including 64 who met the criteria for severe disability (23 percent; 95 percent confidence interval, 18 to 28 percent). When data from 17 assessments by local pediatricians were included, 155 of the 314 infants discharged (49 percent) had no disability. Severe disability is common among children born as extremely preterm infants.

A study was conducted to evaluate the effects of meat and bone meal (MBM) and poultry by-product meal (PBM) as the replacement of fishmeal in the diets on the growth performance, survival and apparent digestibility coefficient (ADC) of Japanese flounder ( Paralichthys olivaceus). The experimental diets included 0%, 20%, 40%, 60% and 80% MBM or PBM replacement of total fishmeal respectively. All diets were iso-nitrogenous and isocaloric. The results showed that there are no significant differences ( P>0.05) in growth performance among the treatments fed with 0% 60% MBM replacement of fishmeal, while the percent weight gain (WG, %), body length gain (BLG, %) and ADC significantly decrease when fishmeal is replaced by 80% MBM. The result showed also that there are no significant differences ( P>0.05) in growth performance and ADC among all treatments fed with the diets with 0% 80% replacements of fishmeal with PBM.

The effects of paid maternity leave: Evidence from Temporary Disability Insurance.

PubMed

Stearns, Jenna

2015-09-01

This paper investigates the effects of a large-scale paid maternity leave program on birth outcomes in the United States. In 1978, states with Temporary Disability Insurance (TDI) programs were required to start providing wage replacement benefits to pregnant women, substantially increasing access to antenatal and postnatal paid leave for working mothers. Using natality data, I find that TDI paid maternity leave reduces the share of low birth weight births by 3.2 percent, and the estimated treatment-on-the-treated effect is over 10 percent. It also decreases the likelihood of early term birth by 6.6 percent. Paid maternity leave has particularly large impacts on the children of unmarried and black mothers. Copyright © 2015 Elsevier B.V.

1981-01-01

The potential size of the onfarm-pumped irrigation market for solar thermal parabolic dish systems in seven high-insolation states is estimated. The study is restricted to the displacement of three specific fuels: gasoline, diesel and natural gas. The model was developed to estimate the optimal number of parabolic dish modules per farm based on the minimum cost mix of conventional and solar thermal energy required to meet irrigation needs. The study concludes that the potential market size for onfarm-pumped irrigation applications ranges from 101,000 modules when a 14 percent real discount rate is assumed to 220,000 modules when the real discount rate drops to 8 percent. Arizona, Kansas, Nebraska, New Mexico and Texas account for 98 percent of the total demand for this application, with the natural gas replacement market accounting for the largest segment (71 percent) of the total market.

Twenty-first century learning in states: the case of the Massachusetts educational system.

PubMed

Driscoll, David P

2006-01-01

A current crisis in education is leaving students less prepared to succeed in the working world than any generation before them. Increasingly complex external, nonacademic pressures have an impact on many of today's students, often causing them to drop out of school. Only 76 percent of Massachusetts high school students graduate, and only 29 percent earn a college degree. National figures are worse. Most educational institutions share a common goal to support students in becoming skilled, productive, successful members of society, but the author argues that this goal is not being met. Despite the constant changes in the world, educational practices have remained static. Most public schools are not adapting to meet the shifting needs of students. Universities are not able to prepare the right mix of prospective employees for the demands of the job market; for example, schools are graduating only 10 percent of the needed engineers. Institutions of higher learning cannot keep up with employers' needs in an evolving global market: strong math, science, and writing abilities; critical thinking skills; and the ability to work in teams. The author draws on exemplary efforts at work in his home state of Massachusetts--whose improvements in student achievement outcomes have been some of the best in the nation--to suggest there is promise in twenty-first century learning. Middle school students involved in a NASA-funded project write proposals, work in teams, and engage in peer review. Older students participate in enhanced, hands-on cooperative school-to-work and after-school programs. Schools are starting to offer expanded day learning, increasing the number of hours they are engaged in formal learning. Yet such programs have not reached significant levels of scale. The author calls for a major shift in education to help today's students be successful in the twenty-first century.

Plotted transects made from south Texas daytime HCMM data show the effect of subvisible cirrus (SCI) clouds in the emissive (IR) band but the effect is unnoticable in the reflective (VIS) band. The depression of satellite indicated temperatures ws greatest in the center of SCi streamers and tapered off at the edges. Pixels of uncontaminated land and water features in the HCMM test area shared identical VIS and IR digital count combinations with other pixels representing similar features. A minimum of 0.015 percent repeats of identical VIS-IR combinations are characteristic of land and water features in a scene of 30 percent cloud cover. This increases to 0.021 percent of more when the scene is clear. Pixels having shared VIS-IR combinations less than these amounts are considered to be cloud contaminated in the cluster screening method. About twenty percent of SCi was machine indistinguishable from land features in two dimensional spectral space (VIS vs IR).

Increasing physical activity among children is a potentially important public health intervention. Quantifying the economic and health effects of the intervention would help decision makers understand its impact and priority. Using a computational simulation model that we developed to represent all US children ages 8–11 years, we estimated that maintaining the current physical activity levels (only 31.9 percent of children get twenty-five minutes of high-calorie-burning physical activity three times a week) would result each year in a net present value of $1.1 trillion in direct medical costs and $1.7 trillion in lost productivity over the course of their lifetimes. If 50 percent of children would exercise, the number of obese and overweight youth would decrease by 4.18 percent, averting $8.1 billion in direct medical costs and $13.8 billion in lost productivity. Increasing the proportion of children who exercised to 75 percent would avert $16.6 billion and $23.6 billion, respectively. PMID:28461358

Low melting high lithia glass compositions and methods

The invention relates to methods of vitrifying waste and for lowering the melting point of glass forming systems by including lithia formers in the glass forming composition in significant amounts, typically from about 0.16 wt % to about 11 wt %, based on the total glass forming oxides. The lithia is typically included as a replacement for alkali oxide glass formers that would normally be present in a particular glass forming system. Replacement can occur on a mole percent or weight percent basis, and typically results in a composition wherein lithia forms about 10 wt % to about 100 wt % of the alkali oxide glass formers present in the composition. The present invention also relates to the high lithia glass compositions formed by these methods. The invention is useful for stabilization of numerous types of waste materials, including aqueous waste uranium oxides The decrease in melting point achieved by the present invention desirably prevents volatilization of hazardous or radioactive species during vitrification.

2009-12-01

New technology using magnetic resonance imaging (MRI) allows the surgeon to place total knee replacement components into each patient's pre-arthritic natural alignment. This study evaluated the initial intra-operative experience using this technique. Twenty-one patients had a sagittal MRI of their arthritic knee to determine component placement for a total knee replacement. Cutting guides were machined to control all intra-operative cuts. Intra-operative events were recorded and these knees were compared to a matching cohort of the senior surgeon's previous 30 conventional total knee replacements. Post-operative scanograms were obtained from each patient and coronal alignment was compared to previous studies using conventional and computer-assisted techniques. There were no intra-operative or acute post-operative complications. There were no differences in blood loss and there was a mean decrease in operative time of 14% compared to a cohort of patients with conventional knee replacements. The average deviation from the mechanical axis was 1.2 degrees of varus, which was comparable to previously reported conventional and computer-assisted techniques. Custom-fit total knee replacement appeared to be a safe procedure for uncomplicated cases of osteoarthritis.

Cardiogenic shock following acute myocardial infarction (AMI-CS) portends a poor prognosis. Short-term mechanical circulatory support devices (MCSDs) provide hemodynamic support for patients with cardiogenic shock but predictors of survival and the ability to wean from short-term MCSDs remain largely unknown. All patients > 18 years old treated at our institution with extra-corporeal membrane oxygenation or short-term surgical ventricular assist device for AMI-CS were studied. We collected acute myocardial infarction details with demographic and hemodynamic variables. Primary outcomes were survival to discharge and recovery from MCSD (i.e. survival without heart replacement therapy including durable ventricular assist device or heart transplant). One hundred and twenty-four patients received extra-corporeal membrane oxygenation or short-term surgical ventricular assist device following acute myocardial infarction from 2007 to 2016; 89 received extra-corporeal membrane oxygenation and 35 short-term ventricular assist device. Fifty-five (44.4%) died in the hospital and 69 (55.6%) survived to discharge. Twenty-six (37.7%) required heart replacement therapy (four transplant, 22 durable ventricular assist device) and 43 (62.3%) were discharged without heart replacement therapy. Age and cardiac index at MCSD implantation were predictors of survival to discharge; patients over 60 years with cardiac index <1.5 l/min per m 2 had a low likelihood of survival. The angiographic result after revascularization predicted recovery from MCSD (odds ratio 9.00, 95% confidence interval 2.45-32.99, p=0.001), but 50% of those optimally revascularized still required heart replacement therapy. Cardiac index predicted recovery from MCSD among this group (odds ratio 4.06, 95% confidence interval 1.45-11.55, p=0.009). Among AMI-CS patients requiring short-term MCSDs, age and cardiac index predict survival to discharge. Angiographic result and cardiac index predict ventricular recovery but 50% of those optimally revascularized still required heart replacement therapy.

Randomized study of whole-abdomen irradiation versus pelvic irradiation plus cyclophosphamide in treatment of early ovarian cancer

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sell, A.; Bertelsen, K.; Andersen, J.E.

From 1 September 1981 to 1 January 1987, 118 patients with FIGO Stage IB, IC, IIA, IIB, and IIC epithelial ovarian cancer were randomized to abdominal irradiation or pelvic irradiation + cyclophosphamide. There was no difference between the regimens with respect to recurrence-free survival (55%) and 4-year overall survival (63%). At routine second-look laparotomy, 16% of patients without clinical detectable tumor showed recurrence. Twenty-five percent of the patients treated with pelvic irradiation + cyclophosphamide had hemorrhagic cystitis, probably caused by radiation damage and cyclophosphamide cystitis. Eight percent had late gastrointestinal symptoms requiring surgery.

Killeen, Therese K.; Greenfield, Shelly F.; Bride, Brian E.; Cohen, Lisa; Gordon, Susan Merle; Roman, Paul M.

2011-01-01

Privately-funded addiction treatment programs were surveyed to increase understanding of assessment and current treatment options for patients with co-occurring substance use and eating disorders. Data were collected from face-to-face interviews with program administrators of a nationally representative sample of 345 private addiction treatment programs. Although the majority of programs reported screening for eating disorders, programs varied in screening instruments used. Sixty-seven percent reported admitting cases of low severity. Twenty-one percent of programs attempt to treat eating disorders. These results highlight the need for education of addiction treatment professionals in assessment, referral and treatment of eating disorders. PMID:21477048

2008-01-01

The aim of this study was to explore the needs and requirements of decision makers in our regional healthcare system for health technology assessment (HTA) products to support portfolio development planning for a new HTA agency in Madrid, Spain. A Delphi study was conducted during 2003. Questionnaires were developed based on a review of products and services offered by other agency members of the International Network of Agencies for Health Technology Assessment, and included preference and prioritization questions to evaluate twenty-two different products and services. The initial Delphi panel involved eighty-seven experts from twenty-one public hospitals, eleven primary healthcare centers, six private hospitals, and eight departments of the Regional Ministry of Health of the Community of Madrid. The global participation rate was 83.9 percent. Ten of the twenty-two possible products were rated of high interest by more than 80 percent of respondents. Important differences in preferences and priorities were detected across different settings. Public hospitals and primary healthcare centers shared a more "micro" perspective, preferring classic technology-centered HTA products, whereas private hospitals and Ministry representatives demanded more "macro" products and services such as organizational model and information system assessments. The high participation rate supports the representativeness of the results for our regional context. The strategic development of an HTA portfolio based on decision makers' needs and requirements as identified in this type of exercise should help achieve a better impact on policy development and decision making.

Use of implantable prostheses for the treatment of urinary incontinence and impotence.

Kaufman, J J; Raz, S

1975-08-01

Silicone-Silastic implants to restore continence and potency have been used in one hundred twenty and twenty-five patients, respectively, and in eight patients a combined anti-impotence and anti-incontinence operation has been performed. The results have been gratifying, the complication rate has been minimal with fewer than five patients in our series having infection and a draining perineal sinus after the incontinence implant, and in no patient have delayed problems with the penile implants developed. Because of the design of the penile implants, fracture is extremely unlikely to occur, and the rods can be replaced if necessary because of inadequate length or asymmetry.

The impact of replacing heavy passenger vehicles (LTVs and SUVs) in the British Columbia fleet with lighter versions.

PubMed

Cooper, Peter J; Zheng, Yvonne; Andersen, Linda; Pellegrini, Nicole

2009-10-01

The study reported in this article addressed the potential safety impact of consumer movement toward smaller vehicle choices by examining the makeup of the full British Columbia (BC) vehicle fleet--from smaller cars to heavy commercial vehicles. The basic assumption made was that some operators of heavy light trucks/vans (LTVs) or sport utility vehicles (SUVs) would, in the short term, be induced to downsize to lighter vehicles of the same type. The 2000-2007 BC crash-claim data at the Insurance Corporation of British Columbia (ICBC) was used to create matrices of average information by culpable and nonculpable entities in two-vehicle collisions in 15 weight categories. Models for the effects of various driver/crash characteristics on injury potential were created and used to adjust the effect calculated solely on the basis of weight change. Levels of heavy LTV/SUV replacement from 0.05 to 0.95 of the current population were tested and the redistribution of vehicles was done in such a way that the relationship between small-large vehicle injury ratio and large-small vehicle mass ratio over the whole fleet remained constant as did the relative proportions of culpable and nonculpable involvements. The net effect of downsizing in the manner assumed for this study was mildly positive in terms of overall injury risk--that is, downsizing resulted in slightly fewer total injuries--but not in the case of fatalities, which tended to be increased by a more substantial margin. However, the results showed that even replacing substantial proportions of the heavy LTV/SUV population would not result in a large impact on safety. Replacing almost all the heavy LTV/SUVs with lighter versions should reduce injuries by less than 1 percent and increase fatalities by 3.5 percent percent. Nevertheless, in terms of persons impacted and the associated costs, the effects would be noticeable. The issue for policy-makers is to judge how the environmental benefits associated with encouraging such change compare with the net costs in terms of safety outcomes.

Outcomes after implant arthroplasty for primary degenerative and posttraumatic osteoarthritis of the proximal interphalangeal joint were different according to the implant design and surgical approach. The purpose of this systematic review was to evaluate outcomes of various types of implant arthroplasty for proximal interphalangeal joint osteoarthritis, with an emphasis on different surgical approaches. The authors searched all available literature in the PubMed and EMBASE databases for articles reporting on outcomes of implant arthroplasty for proximal interphalangeal joint osteoarthritis. Data collection included active arc of motion, extension lag, and complications. The authors combined the data of various types of surface replacement arthroplasty into one group for comparison with silicone arthroplasty. A total of 849 articles were screened, yielding 40 studies for final review. The mean postoperative arc of motion and the mean gain in arc of motion of silicone implant with the volar approach were 58 and 17 degrees, respectively, which was greater than surface replacement implant with the dorsal approach at 51 and 8 degrees, respectively. The mean postoperative extension lag of silicone implant with the volar approach and surface replacement with the dorsal approach was 5 and 14 degrees, respectively. The revision rate of silicone implant with the volar approach and surface replacement with the dorsal approach was 6 percent and 18 percent at a mean follow-up of 41.2 and 51 months, respectively. Silicone implant with the volar approach showed the best arc of motion, with less extension lag and fewer complications after surgery among all the implant designs and surgical approaches.

Replacement dose, metabolism, and bioavailability of levothyroxine in the treatment of hypothyroidism. Role of triiodothyronine in pituitary feedback in humans.

1987-03-26

A change in the formulation of the levothyroxine preparation Synthroid (Flint) in 1982 prompted us to reevaluate the replacement dose of this drug in 19 patients with hypothyroidism. The dose was titrated monthly until thyrotropin levels became normal. The mean replacement dose (+/- SD) was 112 +/- 19 micrograms per day, significantly less (P less than 0.001) than the dose of an earlier formulation--169 +/- 66 micrograms per day--used in a similar study (Stock JM, et al. N Engl J Med 1974; 290:529-33). The fractional gastrointestinal absorption of a tablet of the current formulation is 81 percent, considerably higher than the earlier estimate of 48 percent. Using high-performance liquid chromatographic analysis, we found that the current tablet contains the amount of thyroxine stated by the manufacturer. By measuring the bioavailability of the earlier type of tablet in five patients, we inferred that the strength of the previous tablet had been overestimated. In the present study, the thyrotropin levels of patients on replacement therapy returned to normal when serum triiodothyronine concentrations were not significantly different from those of controls (122 vs. 115 ng per deciliter [1.87 vs. 1.77 nmol per liter]), but when serum thyroxine levels were significantly above those of controls (11.3 vs. 8.7 micrograms per deciliter [145 vs. 112 nmol per liter], P less than 0.001). These findings suggest the possibility that in humans, serum triiodothyronine may play a more important part than serum thyroxine in regulating the serum thyrotropin concentration.

1995-02-01

Between July 1990 and April 1992, a questionnaire was administered to the physicians who saw 62 individuals with a blood lead (PbB) level equal to or higher than 2.40 mumol/liter with occupational inorganic lead exposure, to ascertain the medical management of workers with elevated PbB levels. Most of the 62 cases were seen by their personal physician (50%) or a private physician under contract with the company for which the patient worked (40%). Only eight (13%) patients were seen by a physician in a medical specialty assumed to include training relevant to occupational lead exposure. Fifteen percent of the patients' physicians reported taking no action for the elevated PbB level. Twenty-nine percent did not report retesting the patient (all should have been retested). Twenty-one percent of the 62 patients' physicians reported informing no one, including the patient, of the elevated PbB level. The majority of the physicians did not know the answer or declined to answer a question about what PbB level would prompt them to take six follow-up actions. The results of the physician interviews indicate that medical follow-up on workers with elevated PbB levels may not be adequate to prevent lead poisoning of the workers and their co-workers. Recommendations include methods to increase physician and employer knowledge of the medical management of workers with elevated PbB levels and to increase employer compliance with OSHA standards regarding medical surveillance of lead-exposed workers.

Testing of SRS and RFETS Nylon Bag Material

Laurinat, J.E.

1998-11-03

This report compares the effects of radiation and heating on nylon bagout materials used at the Savannah River Site (SRS) and the Rocky Flats Environmental Technology Site (RFETS). Recently, to simplify the processing of sand, slag, and crucible (SS and C), FB-Line has replaced the low-density polyethylene (LDPE) and polyvinyl chloride (PVC) bags normally used to package cans of plutonium-bearing material with nylon bags. LDPE and PVC are not soluble in the nitric acid dissolver solution used in F-Canyon, so cans bagged using these materials had to be repackaged before they were added to the dissolver. Because nylon dissolves inmore » nitric acid, cans bagged in nylon can be charged to the F-Canyon dissolvers without repackaging, thereby reducing handling requirements and personnel exposure. As part of a program to process RFETS SS and C at SRS, RFETS has also begun to use a nylon bagout material. The RFETS bag materials is made from a copolymer of nylon 6 and nylon 6.9, while the SRS material is made from a nylon 6 monomer. In addition, the SRS nylon has an anti-static agent added. The RFETS nylon is slightly softer than the SRS nylon, but does not appear to be as resistant to flex cracks initiated by contact with sharp corners of the inner can containing the SS and C.2 FB-Line Operations has asked for measurement of the effects of radiation and heating on these materials. Specifically, they have requested a comparison of the material properties of the plastics before and after irradiation, a measurement of the amount of outgassing when the plastics are heated, and a calculation of the amount of radiolytic gas generation. Testing was performed on samples taken from material that is currently used in FB-Line (color coded orange) and at RFETS. The requested tests are the same tests previously performed on the original and replacement nylon and LDPE bag materials.3,4,5. To evaluate the effect of irradiation on material properties, tensile stresses and elongations to break w ere compared for unirradiated and irradiated samples. A standard ASTM method for the measurement of tensile plastic properties6 was used. Properties were measured both parallel to the direction of machining (MD) and transverse to the direction of machining (TD). Tensile strength measurements showed that the ultimate strengths of the SRS replacement bag material decreased by 22 percent in the MD orientation and 17 percent in the TD orientation after irradiation with 5 x 106 rad, a dose equivalent to about 8-9 months exposure in a plutonium can. For the RFETS material, the decreases were 23 percent in the MD orientation and 56 percent in the TD orientation. Although the 5 x 106 dose significantly degraded the properties of both materials, their strengths remained superior to those previously measured for LDPE,4 even after irradiation. Elongations to break also decreased, especially for the SRS material. The decrease for the SRS material were 86 percent in the MD orientation and 95 percent in the TD orientation. For the RFETS material, elongations to break decreased at least 18 percent in the MD orientation and 29 percent in the TD orientation. When samples of both the SRS and RFETS materials were heated in a sealed container to the maximum expected storage can temperature of about 95 C, they outgassed at pressures ranging from 16 to 22 psig. These pressure increases would not cause a can to fail. Using a representative G value of 1.6 molecules/100 ev, the amount of outgassing due to radiolysis was calculated to be negligible. In conclusion, it may be stated that the results of the strength tests and the outgassing measurements and calculations demonstrate that the SRS and RFETS replacement bag materials are acceptable substitutes for LDPE with respect to mechanical properties.« less

Percutaneous pulmonary valve implantation for free pulmonary regurgitation following conduit-free surgery of the right ventricular outflow tract.

Pulmonary regurgitation (PR) following surgery of the right ventricular outflow tract (RVOT) is not innocent and leads to significant right heart dysfunction over time. Recent studies have demonstrated that percutaneous valves can be implanted in conduit free outflow tracts with good outcomes. To evaluate in patients with severe PR--anticipated to require future pulmonary valve replacement--the feasibility and safety of pre-stenting dilated non-stenotic patched conduit-free right ventricular outflow tracts before excessive dilation occurs, followed by percutaneous pulmonary valve implantation (PPVI). Twenty seven patients were evaluated, but only 23 were deemed suitable based on the presence of an adequate retention zone ≤ 24 mm defined by semi-compliant balloon interrogation of the RVOT. A 2 step procedure was performed: first the landing zone was prepared by deploying a bare stent, followed 2 months later by valve implantation. RVOT pre-stenting with an open cell bare metal stent (Andrastent XXL range) was performed at a median age of 13.0 years (range: 6.0-44.9) with a median weight of 44.3 kg (range: 20.0-88.0). Ninety six percent (22/23) of patients proceeded to PPVI a median of 2.4 months (range: 1.4-3.4) after initial pre-stent placement. Twenty one Melody valves and one 26 mm Edwards SAPIEN™ valve were implanted. Complications consisted of embolization of prestent (n = 1), scrunching (n = 4) and mild stent dislocation (n = 2). During follow-up, no stent fractures were observed and right ventricular dimensions decreased significantly. Post-surgical conduit-free non-stenotic RVOT with free pulmonary regurgitation can be treated percutaneously with a valved stent if anatomical (predominantly size) criteria are met. In experienced hands, the technique is feasible with low morbidity. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Medicaid expansion in opt-out states would produce consumer savings and less financial burden than exchange coverage.

PubMed

Hill, Steven C

2015-02-01

In the twenty-three states that have decided against expanding Medicaid under the Affordable Care Act, uninsured adults who would have been eligible for Medicaid and have incomes at or above the federal poverty guidelines are generally eligible for Marketplace (insurance exchange) premium tax credits and plans with generous benefits. This study compared estimated out-of-pocket spending for care and premiums, as well as the financial burdens they impose, for the families of these adults under two simulation scenarios: obtaining coverage through a silver plan with subsidized cost sharing and enrolling in expanded Medicaid. Compared with Marketplace coverage, Medicaid would more than halve average annual out-of-pocket spending ($938 versus $1,948), while dramatically reducing the percentage of adults in families with out-of-pocket expenses exceeding 10 percent or 20 percent of income (6.0 percent versus 17.1 percent and 0.9 percent versus 3.7 percent, respectively). Larger reductions would be seen for families with smokers, who under Medicaid would no longer be subject to Marketplace tobacco user surcharges. Medicaid expansion may offer a greater opportunity than access to Marketplace insurance to promote the financial well-being of previously uninsured low-income adults.

Teenager counseling to recognize risks and reinforce strengths is carried out in a primary care outpatient clinic since 2003. To describe the epidemiology and causes for consultation in this teenage counseling program. Retrospective review of the records of 116 teenagers (median age 13 years, 67% females) that received teenager counseling. Seventy percent of women and 50% of men came from nuclear families. More than two thirds were primogenital. Most adolescents were accompanied by their mother, that were the main adult raw model. Fifty percent had dysfunctional families. All were attending school regularly and 21% of women and 29% of men had repeated a school level. Sixty eight percent of women and 62% of men declared to have a life project. Twenty percent were worried about their physical appearance. Seventy seven percent of women and 62% of men considered themselves as happy. Thirty six percent of women and 14% of men smoked. The figures for alcohol consumption were 21% and 14%, respectively. The causes for consultation were obesity, overweight, unspecific symptoms, behavioral problems, bad school achievement, communication problems or pregnancy. Reasons for counseling were family dysfunction, low self esteem, bad school achievement and information about sexuality. The information obtained could help to improve the interdisciplinary work and to coordinate counseling with the family and schools.

Defining and managing biohazardous waste in U.S. research-oriented universities: a survey of environmental health and safety professionals.

Mecklem, Robin Lyn; Neumann, Catherine M

2003-01-01

A survey was conducted of environmental health and safety professionals responsible for biohazardous waste management at 122 institutions. The overall response rate was 82.6 percent (100 out of 122). Results indicate that university policies for biohazardous waste are heavily influenced by state environmental regulations, the Occupational Safety and Health Administration Bloodborne Pathogens Standard, and the biosafety guidelines of the Centers for Disease Control and Prevention and the National Institutes of Health. With respect to definition of waste, 84 percent of the universities treat non-infectious human-cell-culture waste as biohazardous. Sharp items, including hypodermic needles, syringes with needles, and scalpel blades, are commonly treated (by 85 percent of universities) as biohazardous sharps regardless of contamination status. Importantly, while 90 percent of universities use autoclave sterilization for waste treatment, only 52 percent use a biological indicator to validate the process. On-site incineration is currently used by 42 percent of universities. Twenty-two of 42 incinerators are hospital/medical/infectious-waste incinerators, and 10 of these will continue to operate under the U.S. Environmental Protection Agency's revised incinerator regulations. Eighty-seven percent of the respondents indicated that some portion of their university's biohazardous waste is treated and disposed of through a licensed medical waste hauler (MWH). To ensure compliance with institutional policy, most universities segregate and package waste, train waste generators, and conduct inspections.

Association between cesarean delivery rate and body mass index.

Berendzen, Jodi A; Howard, Bobby C

2013-01-01

The purpose of this study was to evaluate the association between cesarean delivery rate and body mass index (BMI) for the patient population served by the University of Tennessee Medical Center in Knoxville, TN. A retrospective, cohort study was conducted using the perinatal birthlog fromJanuary 1, 2009 through December 31, 2009. The database totaled 2,399 women. Women who delivered > or = 23 weeks gestational age were included. Those missing data imperative to our study (height, weight, mode of delivery) were excluded. Thus, our study included 2,235 women. Cesarean delivery rate was calculated for each of the five BMI categories. Univariate analysis using Chi square, Mann-Whitney U test and independent t-test were used to describe associations between body mass index, mode of delivery and other independent variables. Additional analyses were made on the subset of nulliparous women. Using prepregnancy BMI, 6.7 percent of our population was underweight, 44.3 percent normal weight, 22.6 percent overweight, 20.6 percent obese, and 5.8 percent morbidly obese. The overall cesarean delivery rate was 36.2 percent. Twenty-six percent of underweight and 31.4 percent of normal weight women required cesarean delivery, while 39.1 percent of overweight, 40.8 percent of obese and 56.6 percent of morbidly obese women required cesarean delivery. In addition to cesarean delivery, hypertensive disorders (OR 3.29; 95% CI 2.51-4.31) and diabetes (OR 5.27; 95% CI 3.73-7.44) complicated significantly more pregnancies of obese women than normal weight women. There was an increased rate of cesarean delivery as BMI increased. Increased BMI is also associated with other pregnancy complications, including hypertensive disorders and diabetes.

Analysis of surface damage in retrieved carbon fiber-reinforced and plain polyethylene tibial components from posterior stabilized total knee replacements.

Wright, T M; Rimnac, C M; Faris, P M; Bansal, M

1988-10-01

The performance of carbon fiber-reinforced ultra-high molecular weight polyethylene was compared with that of plain (non-reinforced) polyethylene on the basis of the damage that was observed on the articulating surfaces of retrieved tibial components of total knee prostheses. Established microscopy techniques for subjectively grading the presence and extent of surface damage and the histological structure of the surrounding tissues were used to evaluate twenty-six carbon fiber-reinforced and twenty plain polyethylene components that had been retrieved after an average of twenty-one months of implantation. All of the tibial components were from the same design of total knee replacement. The two groups of patients from whom the components were retrieved did not differ with regard to weight, the length of time that the component had been implanted, the radiographic position and angular alignment of the component, the original diagnosis, or the reason for removal of the component. The amounts and types of damage that were observed did not differ for the two materials. For both materials, the amount of damage was directly related to the length of time that the component had been implanted. The histological appearance of tissues from the area around the component did not differ for the two materials, except for the presence of fragments of carbon fiber in many of the samples from the areas around carbon fiber-reinforced components.

2009-09-01

Colon injuries are increasingly being treated safely by primary repair in spite of the high risk of septic complications. This is a retrospective study of the pattern, management and outcome in patients treated for penetrating colon injuries at Olabisi Onabanjo University Teaching Hospital, Sagamu over a 7 year period (January 1995-December 2001). Records of thirty-two patients were studied. Gunshots (75 percent) and knife stabs (18.75 percent) accounted for ninety-four percent of penetrating colon injuries. Associated intra-abdominal injuries were present in 22 patients (68.8 percent). Eight (twenty-five percent) patients presented in shock. Moderate to major faecal contamination was present in 30 (93.8%) patients. Severe colon injury occurred in nine patients. The eighteen patients with right colon wounds were managed by primary repair. All the fourteen patients with left colon wounds had a diverting colostomy alongside repair or resection. Complications included wound infection (56.7 percent) and septicaemia (31.7 percent). Eleven patients died, giving an overall mortality rate of 34.4 percent. Mortality was significantly associated with shock on admission (p<0.02), degree of faecal contamination (p<0.05) and severity of colon injury (p<0.01). Colostomy did not affect mortality. (P<0.1). In this study primary repair was employed in 56% of patients with penetrating colon injuries. The routine use of diverting colostomy for all left colon injuries can no longer be justified in current surgical practice as colostomy did not affect mortality.

The psychosomatic care of patients after surgical treatment must comprise the analysis of quality of life with colostomy. Five different parameters were assessed of 100 colostomy patients. Sixty-one percent of our patients had skin irritation problems. Twenty-eight patients applied regular irrigation. Seventy-two percent of these had daily motions, 20% had bidaily, the remaining 8% had irregular bowel movements. Seventeen percent of the nonirrigating patients observed very irritating fecal discharge around the stoma. Embarrassing noises concomittant with bowel movements were observed by 42% and 45% struggled with bad odors. Irrigating patients had hardly any of these problems. For 65% of the patients the idea of having a colostoma meant the greatest psychological burden before the operation. The stress situation culminated in the immediate postoperative period in 10%. Forty percent of those asked were seriously worried about the reaction of their social environment. In 65% a significant decrease of social relations could be observed. Sixteen percent reported an increased social activity after colostomy had been performed. Sixty percent admitted considering the option of suicide at least once. Thirty-five percent revealed to have any kind of sexual problems after colostomy. Eight of our 100 colostomy patients experienced serious adverse reactions from their family members. In eighty percent of the cases family members showed great sympathy although they acted naively. The quality of life of colostomy patients may be best taken care of by qualified stomatherapists, out-patient proctology departments and the ileo-colostomy movement (ILCO).

2011-08-01

The aim of this study was to determine the incidence of facial clefting in Cambridge, UK, using multiple resources of ascertainment and to relate the findings to antenatal ultrasound screening (AUS) detection rates. AUS records from an obstetric ultrasound department, post-natal records from the regional craniofacial unit, and autopsy reports of foetuses over 16 weeks' gestational age from a regional pathology department from 1993 to 1997 were retrospectively reviewed. Cross-referencing between the three data sets identified all cases of facial clefts. Of 23,577 live and stillbirths, 30 had facial clefts. AUS detected 17 of these. Sixteen of the 30 had isolated facial clefts. Others had associated anomalies, chromosomal defects, or syndromes. Percentages and confidence intervals were calculated from the above data. Twenty-one resulted in live births, seven terminations, and two foetal deaths. Overall, detection rate by AUS was 65 percent [67 percent isolated cleft lip, 93 per cent cleft lip and palate (CLP), and 22 percent isolated cleft palate], with no false positives. The incidence of facial clefts was 0.127 percent (95 percent confidence interval 0.089-0.182 percent); the incidence for isolated CLP was lower than previously reported: 0.067 percent (0.042-0.110 percent). With one exception, all terminations were in foetuses with multiple anomalies. The figures presented will enable joint CLP clinics to give parents information of termination rates. The study allows pre-pregnancy counselling of families previously affected by clefting about the reliability of AUS detection rates.

Application of a multipurpose unequal probability stream survey in the Mid-Atlantic Coastal Plain

USGS Publications Warehouse

Ator, S.W.; Olsen, A.R.; Pitchford, A.M.; Denver, J.M.

2003-01-01

A stratified, spatially balanced sample with unequal probability selection was used to design a multipurpose survey of headwater streams in the Mid-Atlantic Coastal Plain. Objectives for the survey include unbiased estimates of regional stream conditions, and adequate coverage of unusual but significant environmental settings to support empirical modeling of the factors affecting those conditions. The design and field application of the survey are discussed in light of these multiple objectives. A probability (random) sample of 175 first-order nontidal streams was selected for synoptic sampling of water chemistry and benthic and riparian ecology during late winter and spring 2000. Twenty-five streams were selected within each of seven hydrogeologic subregions (strata) that were delineated on the basis of physiography and surficial geology. In each subregion, unequal inclusion probabilities were used to provide an approximately even distribution of streams along a gradient of forested to developed (agricultural or urban) land in the contributing watershed. Alternate streams were also selected. Alternates were included in groups of five in each subregion when field reconnaissance demonstrated that primary streams were inaccessible or otherwise unusable. Despite the rejection and replacement of a considerable number of primary streams during reconnaissance (up to 40 percent in one subregion), the desired land use distribution was maintained within each hydrogeologic subregion without sacrificing the probabilistic design.

This study assessed the merits of introducing a novel, online interactive training module designed to positively engage dental students and teach them to recognize and report signs of child abuse and neglect. The study aimed to determine if the online training module educated the students equivalently or better than a lecture presentation of the same content. Seventy-two students from Columbia University College of Dental Medicine's class of 2015 (90 percent of the class) agreed to participate and were randomly assigned to either a traditional lecture-based presentation or the online training module. Study participants were given a twenty-question multiple-choice pretest on their knowledge of child abuse recognition and reporting prior to the start of the study. The same instrument was administered as a posttest. At the end of the training, questionnaires were also given to both groups to assess students' perceptions of the two educational methodologies. The results showed that the interactive online training module was more effective than the lecture-based method. Results of the posttest comparison of the two groups were statistically significant (p<0.05) in favor of the online training group. Additionally, the students reported that the interactive online training module was engaging and a helpful resource, but on average they did not prefer it as a total replacement for the lecture-based approach.

Purpose To determine the safety of sentinel lymph node biopsy as a replacement for inguinal femoral lymphadenectomy in selected women with vulvar cancer. Patients and Methods Eligible women had squamous cell carcinoma, at least 1-mm invasion, and tumor size ≥ 2 cm and ≤ 6 cm. The primary tumor was limited to the vulva, and there were no groin lymph nodes that were clinically suggestive of cancer. All women underwent intraoperative lymphatic mapping, sentinel lymph node biopsy, and inguinal femoral lymphadenectomy. Histologic ultra staging of the sentinel lymph node was prescribed. Results In all, 452 women underwent the planned procedures, and 418 had at least one sentinel lymph node identified. There were 132 node-positive women, including 11 (8.3%) with false-negative nodes. Twenty-three percent of the true-positive patients were detected by immunohistochemical analysis of the sentinel lymph node. The sensitivity was 91.7% (90% lower confidence bound, 86.7%) and the false-negative predictive value (1-negative predictive value) was 3.7% (90% upper confidence bound, 6.1%). In women with tumor less than 4 cm, the false-negative predictive value was 2.0% (90% upper confidence bound, 4.5%). Conclusion Sentinel lymph node biopsy is a reasonable alternative to inguinal femoral lymphadenectomy in selected women with squamous cell carcinoma of the vulva. PMID:22753905

2014-01-01

Management of short bowel syndrome (SBS) aims to achieve intestinal autonomy to prevent fluid, electrolyte, and nutrient deficiencies and maintain adequate development. Remnant intestinal adaptation is required to obtain autonomy. In the newborn pig, colostrum has been shown to support intestinal development and hence adaptive processes. The efficacy of bovine colostrum to improve intestinal function in children with SBS was evaluated by metabolic balance studies. Nine children with SBS were included in a randomized, double-blind, crossover study. Twenty percent of enteral fluid intake was replaced with bovine colostrum or a mixed milk diet for 4 weeks, separated by a 4-week washout period. Intestinal absorption of energy and wet weight was used to assess intestinal function and the efficacy of colostrum. Colostrum did not improve energy or wet weight absorption compared with the mixed milk diet (P = 1.00 and P = .93, respectively). Growth as measured by weight and knemometry did not differ between diets (P = .93 and P = .28). In these patients, <150% enteral energy absorption of basal metabolic rate and 50% enteral fluid absorption of basal fluid requirement suggested intestinal failure and a need for parenteral nutrition (PN). Inclusion of bovine colostrum to the diet did not improve intestinal function. Metabolic nutrient and wet weight balance studies successfully assessed intestinal function, and this method may distinguish between intestinal insufficiency (non-PN-dependent) and intestinal failure (PN-dependent) patients.

This study was designed to determine if orthodontic residents are being trained to use lasers in the postgraduate orthodontic residency programs of the United States and Canada. An anonymous electronic survey was sent to the program director/chair of each of the seventy orthodontic residency programs, and thirty-seven (53 percent) of the programs responded. Of these thirty-seven programs, twenty-eight (76 percent) reported providing patient treatment with lasers in the orthodontic graduate program, eight (22 percent) said they do not provide treatment in the orthodontic graduate program, and one program (3 percent) reported providing laser training but not using lasers on patients. Gingivectomy and canine exposure were reported as the most common procedures that residents perform with a laser, while debonding of orthodontic brackets was the least common procedure performed with a laser. A diode laser was the most common type of laser used. Of the eight programs (22 percent) not offering laser training, four indicated having no plans to begin using lasers or training on their use. The other four indicated that they have plans to incorporate laser use in the future.

The effect of temperature on the tensile properties of annealed 304L stainless steel and HERF 304L stainless steel forgings was determined by completing experiments over the moderate range of -40 F to 160 F. Temperature effects were more significant in the annealed material than the HERF material. The tensile yield strength of the annealed material at -40 F averaged twenty two percent above the room temperature value and at 160 F averaged thirteen percent below. The tensile yield strength for the three different geometry HERF forgings at -40 F and 160 F changed less than ten percent from room temperature.more » The ultimate tensile strength was more temperature dependent than the yield strength. The annealed material averaged thirty six percent above and fourteen percent below the room temperature ultimate strength at -40 F and 160 F, respectively. The HERF forgings exhibited similar, slightly lower changes in ultimate strength with temperature. For completeness and illustrative purposes, the stress-strain curves are included for each of the tensile experiments conducted. The results of this study prompted a continuation study to determine tensile property changes of welded 304L stainless steel material with temperature, documented separately.« less

Preliminary Evaluation of a Turbine/Rotary Combustion Compound Engine for a Subsonic Transport. [fuel consumption and engine tests of turbofan engines

Civinskas, K. C.; Kraft, G. A.

1976-01-01

The fuel consumption of a modern compound engine with that of an advanced high pressure ratio turbofan was compared. The compound engine was derived from a turbofan engine by replacing the combustor with a rotary combustion (RC) engine. A number of boost pressure ratios and compression ratios were examined. Cooling of the RC engine was accomplished by heat exchanging to the fan duct. Performance was estimated with an Otto-cycle for two levels of energy lost to cooling. The effects of added complexity on cost and maintainability were not examined and the comparison was solely in terms of cruise performance and weight. Assuming a 25 percent Otto-cycle cooling loss (representative of current experience), the best compound engine gave a 1.2 percent improvement in cruise. Engine weight increased by 23 percent. For a 10 percent Otto-cycle cooling loss (representing advanced insulation/high temperature materials technology), a compound engine with a boost PR of 10 and a compression ratio of 10 gave an 8.1 percent lower cruise than the reference turbofan.

Samples from the B-cloth cover for a battery orbit replaceable unit from the International Space Station were characterized using optical and electron microscopy, UV-vis-NIR spectrophotometry, and x-ray energy dispersive spectroscopy. Results showed that in areas where the fabric was exposed to solar radiation the absorptance increased by as much as 20 percent, and the peak difference was in the ultraviolet, indicating that the increased absorptance may have been due to radiation. The emissivity of the material over a temperature range of 300 - 700 K was essentially unchanged.

Characterize the social profile and the need of information from patients with refractory epilepsy. A semi-structured questionnaire was applied to 103 patients to investigate sociodemographic aspects, pharmacotherapy and any doubts about epilepsy. Patients were highly dependent on having a free and accessible supply of antiepileptic drugs. Sixty-eight percent of the population was unemployed, and 26% confirmed receiving social security benefits due to epilepsy. Twenty-nine percent of the population reached high school. Eighty-five percent of the patients had at least one doubt about epilepsy; treatment and epilepsy aspects in general were the main topics. As observed in developed countries, patients with refractory epilepsy from a developing country also have high rates of unemployment and low educational levels. The results raise a concern about the need of information about epilepsy by patients and their families, urging the necessity to invest in strategies to solve this deficiency in knowledge.

2003-01-01

It was the purpose of this study to evaluate the revascularization of primary nerve repair and grafts using orthogonal polarization spectral (OPS) (Cytometrix, Inc.) imaging, a novel method for real-time evaluation of microcirculatory blood flow. Twenty male Sprague Dawley rats (250 g) were anesthetized with vaporized halothane and surgically prepared for common peroneal nerve resection. Group I animals (n = 10) underwent primary neurorraphy following transection, utilizing a microsurgical technique with 10-0 nylon suture. Group II (n = 10) animals had a 7-mm segment of nerve excised, reversed, and subsequently replaced as a nerve graft under similar techniques. All animals were evaluated using the OPS imaging system on three portions (proximal, transection site/graft, and distal) of the nerve following repair or grafting. Reevaluation of 5 animals randomly selected from each group using the OPS imaging system was again performed on days 14 and 28 following microsurgical repair/grafting. Values were determined by percent change in vascularity of the common peroneal nerve at 0 hr following surgery. Real-time evaluation of blood flow was utilized as an additional objective criterion. Percent vascularity in group I and II animals increased from baseline in all segments at day 14. By day 28, vascularity in nerves of group I rats decreased in all segments to values below baseline, with the exception of the transection site, which remained at a higher value than obtained directly after surgical repair. In group II animals, vascularity remained above baseline in all segments except the distal segment, which returned to vascularity levels similar to those at 0 hr. Further, occlusion of the vessels demonstrated in the graft and distal segments following initial transection appeared to be corrected. This study suggests that revascularization may occur via bidirectional inosculation with favored proximal vascular growth advancement. The use of real-time imaging offers a unique evaluation of tissues through emerging technologies. Copyright 2003 Wiley-Liss, Inc.

The first Björk-Shiley convexoconcave (BSCC) prosthetic heart valves were implanted in 1978. The 25th anniversary provided a stimulus to summarize the research data relevant to BSCC valve fracture, patient management, and current clinical options. Published and unpublished data on the risks of BSCC valve fracture and replacement were compiled, and strategies for identifying candidates for prophylactic valve reoperation were summarized. By December 2003, outlet strut fractures (OSFs), often with fatal outcomes, had been reported in 633 BSCC valves (0.7% of 86,000 valves implanted). Fractures still continue to occur, but average rates of OSFs in 60 degrees valves are now <0.1% per year. OSF risk varies markedly by valve characteristics, especially valve angle and size, with weaker effects associated with other manufacturing variables. OSF risks are mildly lower among women than men but decline sharply with advancing age. The risks of valve replacement typically greatly exceed those of OSF. By comparing individualized estimated risks of OSF versus valve replacement, guidelines have been developed to identify the small percentage of BSCC patients (mostly younger men) who would be expected to have a gain in life expectancy should reoperative surgery be performed. Twenty-five years after the initial BSCC valve implants, fractures continue to occur. Continued monitoring of BSCC patients is needed to track and quantify risks and enable periodic updating of guidelines for patients and their physicians.

Nuclear renal scan is currently the gold standard imaging study to determine differential renal function. We propose helical CT as single modality for both the anatomical and functional evaluation of kidney with impaired function. In the present study renal parenchymal volume is measured and percent total renal volume is used as a surrogate marker for differential renal function. The objective of this study is to correlate between differential renal function estimation using CT-based renal parenchymal volume measurement with differential renal function estimation using (99m)TC - DTPA renal scan. Twenty-one patients with unilateral obstructive uropathy were enrolled in this prospective comparative study. They were subjected to (99m)Tc - DTPA renal scan and 64 slice helical CT scan which estimates the renal volume depending on the reconstruction of arterial phase images followed by volume rendering and percent renal volume was calculated. Percent renal volume was correlated with percent renal function, as determined by nuclear renal scan using Pearson coefficient. RESULTS AND OBSERVATION: A strong correlation is observed between percent renal volume and percent renal function in obstructed units (r = 0.828, P < 0.001) as well as in nonobstructed units (r = 0.827, P < 0.001). There is a strong correlation between percent renal volume determined by CT scan and percent renal function determined by (99m)TC - DTPA renal scan both in obstructed and in normal units. CT-based percent renal volume can be used as a single radiological tests for both functional and anatomical assessment of impaired renal units.

The objective of this study was to assess Nigerian dental therapy students' knowledge, attitudes, and willingness to care for patients with HIV. A twenty-six-item questionnaire was used to conduct a cross-sectional study of the dental therapy students of Federal School of Dental Therapy and Technology, Enugu State, Nigeria. The level of knowledge of HIV transmission and prevention among the respondents was high. However, misconceptions about the transmission of HIV through blood donation, mosquito bite, and sharing cups and plates were noted. Erroneous descriptions of HIV as harmless, self-limiting, antibiotic sensitive infection, punishment virus, and contagious infection were also reported. More than half (56.2 percent) and 25.2 percent of the respondents, respectively, expressed feelings of empathy and sympathy towards individuals with HIV. About three-quarters (74.3 percent) expressed willingness to treat patients with HIV, and 87.6 percent expressed confidence in their ability to prevent occupational HIV acquisition. This expressed confidence was significantly associated with their willingness to treat patients with HIV. More than half (55.7 percent) of the respondents reported they can adequately deliver HIV-related information to patients. A total of 86.2 percent said there is a need for training dental therapists in the clinical care of patients with HIV, and 89.0 percent said that dental therapists can play a significant role in the dissemination of HIV-related information. The vast majority (90.0 percent) expressed willingness to disseminate HIV-related information, and the majority (70.5 percent) considered the dental therapist the most suitable dental professional to give HIV-related information to patients.

Facebook is the leading online media platform used by plastic surgeons. This study examined Facebook use among plastic surgeons and its perceived impact. A survey on Facebook use was distributed to two groups of plastic surgeons: 500 with professional Facebook pages and 500 without Facebook pages. Responses were stripped of identifying information and analyzed for statistical significance (p < 0.05). One hundred twenty-three total surveys were completed (12.3 percent response rate). No respondents with Facebook reported a negative impact on their practice, whereas 57 percent reported a very positive or positive impact. There was no correlation with perceived impact and number of "likes." Perceived advantages of Facebook included facilitation of patient feedback/communication (77 percent) and increased practice exposure (67 percent). Many surgeons (15 to 36 percent) did not follow the direct impact of Facebook on their practices. Some reported that Facebook was responsible for only one to 50 professional Web site hits and less than 5 percent of their new patient referrals in the past year. Estimated conversion-to-surgery rates were highly variable for Facebook users and nonusers. Most Facebook nonusers (67 percent) expected a "neutral" impact, expressing more concerns about unsolicited advertising (51 percent) and wasting time (47 percent). Plastic surgeons tend to perceive Facebook's impact on their practices as positive, but most do not track its direct effects on professional Web site hits, new referrals, or conversion-to-surgery rates. Plastic surgeons using Facebook are encouraged to monitor these parameters to determine whether its continued use is actually worthwhile.

To compare continuous combined hormone replacement therapy (ccHRT) and raloxifene with respect to compliance and quality of life, which were predefined secondary endpoints of a large, prospective study designed to investigate the uterine effects of both treatments. Double-blind, randomised controlled trial of six-month duration. One hundred and twenty-nine gynaecology hospital departments, clinics or practices specialised in women's healthcare, located in Europe, South Africa and Israel. Healthy postmenopausal women (n = 1008). Changes in quality of life using the Women's Health Questionnaire (WHQ) and compliance using a compliance questionnaire and pill count. Adverse event and early discontinuation rates and satisfaction with treatment using a visual analogue scale (VAS). Women taking raloxifene reported greater satisfaction with their treatment as assessed on the VAS (P = 0.004), and a lower proportion, as compared with ccHRT, reported being worried by the treatment (9.6% vs 20.2%, P < 0.01). Women taking ccHRT reported greater deterioration in scores from the WHQ for depressed mood and menstrual symptoms than those taking raloxifene (P < 0.01). For memory, vasomotor symptoms and sexual behaviour, the ccHRT group reported significantly greater mean improvements (P < 0.05). Over half (58.8%) of those taking raloxifene noticed no effect, 37.7% felt better and 3.4% felt worse as measured using the compliance questionnaire. Fifty percent of the women taking ccHRT felt better, 37.8% noticed no effect but over 10% felt worse. More women on raloxifene (94.6%) than on ccHRT (85.9%) reported that they were taking their double-blinded medication regularly (P < 0.01). A lower rate of adverse event-related discontinuations, the lack of negative effects on quality of life and a smaller proportion of women being worried by the drug treatment were associated with higher treatment satisfaction and better compliance in postmenopausal women taking ccHRT or raloxifene.

Banks, A.J.

The purpose of this report is to examine the impact of asbestos abatement on the construction industry. It is estimated that the cleanup effort may cost $100 billion over the next twenty five years. More than 733,000 structures, or twenty percent of U. S. commercial and public properties are believed to contain asbestos. Some of the material is in a friable state. This asbestos is crumbling into microscopic fibers that can float in through the air. The use of asbestos was restricted after high doses of its fibers were found to scar lungs, causing cancer and other diseases. Construction businessesmore » use 50 percent of the U. S. supply of asbestos in asbestos cement pipes, sheets, siding shingles, floor tiles, coatings, and sealants. Some 29,000 workers install asbestos insulation during building construction. Other estimates of exposed workers include 20,400 in demolition, 67,800 in abatement, 82,500 in general building renovation, 135,700 doing routine maintenance in buildings, and 183,200 in routine maintenance in general industry. The demand for asbestos removal services exceeds the ability of the industry to supply it safely. Asbestos management and removal are major issues for the construction industry world wide.« less

Background: Gynecomastia during adolescence is common though etiology is not clear. We studied the clinical and hormonal profile of adolescent patients with gynecomastia. Methodology: Patients who had onset of breast development between age 10 and 20 years were included in this study. Their clinical profile, biochemical, and hormonal parameters were studied. Results: Of 94 patients with gynecomastia, 4 had hypogonadotropic hypogonadism, 4 had hypergonadotropic hypogonadism, and 1 had fibroadenosis, but in majority (90.4%), no apparent cause for breast enlargement was evident. In the idiopathic group, majority were obese (63%). Fourteen (16%) patients had impaired fasting glucose or impaired glucose tolerance. Another twenty patients had subtle abnormalities (high 1 h glucose or glucose peak at 2 h). Twenty-nine percent of lean and 38% of obese patients had mild abnormalities in glucose profile. Sixty percent of patients had family background of diabetes. Obese patients had lower testosterone as compared to lean patients; however, estradiol, luteinizing hormone, and follicle-stimulating hormone levels were similar in the two groups. Conclusion: Gynecomastia during adolescence is associated with obesity, dysglycemia, and family background of diabetes mellitus. PMID:28217517

1994-07-01

The authors examined students' perceptions, attitudes, and experiences of sexual harassment by faculty members at a state university, using a sample of 1,139 graduate and undergraduate students. Twenty-six percent (292) of those in the sample responded. The instrument used in the study, adapted from a survey previously used at the University of Iowa, operationally defined eight categories of behavior: sexist comments, undue attention, verbal sexual advances, body language, invitations, physical advances, explicit sexual propositions, and sexual bribery. As many as 8% of the respondents indicated they had experienced the three most extreme forms of harassment--physical advances, explicit sexual propositions, and sexual bribery. Although most students thought they would report sexual harassment, only three incidents of the most extreme forms of sexual harassment were actually reported. Those who experienced harassment indicated that it generally came from one rather than from several faculty members and that it came from both male and female faculty. Twenty-three percent of the men reported experiencing sexist comments, and 5 male students reported they had experienced at least one of the three most extreme forms of sexual harassment. Recommendations for policy revisions and campus health promotion programming that were made following the survey are discussed.

2015-01-01

To describe perceived benefits and safety of community water fluoridation (CWF) and investigate factors associated with those perceptions of CWF among respondents to a proprietary survey in the United States. We obtained data from the 2009 HealthStyles survey, a convenience sample of 4,556 respondents. Pearson's chi-squared and logistic regression were used to determine the associations between certain socio-demographic factors and perceptions regarding the safety and health benefits of CWF. The majority of respondents (55.3 percent) strongly agreed/agreed that CWF was safe, while 31.5 percent were neutral, and 13.2 percent disagreed/strongly disagreed. Twenty-seven percent of respondents reported CWF had no health benefit, 57.3 percent reported some benefit, and 15.5 percent reported great benefit. Perceived CWF safety and benefit in the bivariate analyses were associated with gender, age, race/ethnicity, education, marital status, income, sealant knowledge, CWF knowledge, past year dental utilization, and perceived vaccine safety. Respondents with knowledge of CWF (47.9 percent) were more likely to agree that it was safe (69.8 percent) than those who reported no knowledge (41.3 percent). Among respondents who said childhood vaccines were not safe (4.0 percent), almost half disagreed that CWF was safe. Logistic regression results indicated that perceived CWF safety and benefits increased with CWF knowledge, perceived vaccine safety, and income. Although only a minority of the US population perceived CWF as unsafe or providing no benefit to health, perceptions regarding CWF varied by knowledge of CWF and socio-demographic factors. Oral health promotion activities should consider these differing perceptions of CWF among groups to tailor oral health messaging appropriately. © 2015 American Association of Public Health Dentistry.

The aim of this study was to evaluate the replacement effect of wheat bran with spineless cactus and urea in heifers. Twenty-four heifers with an average initial weight of 185 ± 13 kg were used in this experiment. Four levels of spineless cactus corrected with urea and ammonium sulfate (9:1) were studied: 0, 33, 66, and 100 % replacement with wheat bran. Samples of feed, orts, and feces were analyzed to estimate the intake and digestibility of dry matter (DM) and nutrients. Indigestible neutral detergent fiber was used as an internal marker. The experiment was conducted in a completely randomized design. Dry matter, neutral detergent fiber, and total digestible nutrient intake demonstrated a quadratic effect (P < 0.05). Rumen degradable protein intake increased linearly (P < 0.05). The maximum DM digestibility was estimated to be 0.67 with a 43 % replacement. Crude protein and NDF digestibility increased linearly (P < 0.05). The total body weight gain and average daily gain decreased linearly with the replacement. Thus, it is practical to replace wheat bran with spineless cactus containing urea and ammonium sulfate up to 66 % in sugar cane-based diets.

The objective of this study was to evaluate the effects of sugar beet tubers as a replacer to green fodder on production performance and economics of lactating Surti buffaloes. This trial was conducted at the Livestock Research Station, Navsari Agricultural University, Navsari. Twenty lactating Surti buffaloes in a changeover experimental design were selected to assess the effects of replacing green fodder with sugar beet (Beta vulgaris L.) tubers on production performance, economics of feeding sugar beet and blood biochemical profile. Half (50%) of the hybrid Napier was replaced with sliced sugar beet tubers in the ration of experimental animals. Partial replacement of hybrid Napier with that of sugar beet tubers numerically improved dry matter intake, milk yield, 4% fat corrected milk and milk composition parameters such as fat, solid non-fat, protein and lactose, but not significantly. The blood parameters were in normal range and non-significant except that of glucose and triglycerides, which were increased in the sugar beet group. Replacing sugar beet tubers also proved to be cost-effective with improved net profit around Rs. 6.63/day. It can be concluded that 50% hybrid Napier fodder can be replaced with sugar beet tubers without any adverse effect on animal production performance, milk composition blood biochemical profile and economics of feeding.

Multiple-choice questionnaires devised to evaluate knowledge and awareness of testicular carcinoma and the practice of testicular self-examination (TSE) were distributed to 717 male soldiers and 200 military physicians in the Israeli army. Twenty-one percent of the soldiers had received explanations about the importance of TSE; 16% actually received instruction on TSE; yet only 2% practiced TSE regularly. Seventy percent of physicians had been taught how to examine testicles, but only 10% of physicians examined testicles in their routine physical exams. TSE was practiced most frequently among soldiers who had received instruction in the technique. Physicians should encourage their young male patients to practice TSE.

This study examined hospital administrators' experiences with the National Practitioner Data Bank. One hundred forty-nine rural hospital administrators completed questionnaires assessing their perceptions of the data bank. Nearly 90% of respondents rated the data bank as an important source of information for credentialing. Three percent indicated it had directly affected privileging decisions; 43% and 34%, respectively, believed the costs exceeded or equaled the benefits. Twenty percent reported changes that could decrease disciplinary action reports to the data bank. While the National Practitioner Data Bank is an important source of information to rural hospitals, it may, affect few credentialing decisions and motivate behavioral changes that could have a paradoxical effect on quality assurance.

Evaluation of a local exhaust system used in the manufacture of small parts made of reinforced plastic.

PubMed

Lazure, L P

2000-09-01

Fiber-reinforced plastics are used to manufacture a large variety of products, particularly for the transportation sector. Hand lay-up molding and projection molding are the main methods of manufacture. The users of these processes are exposed to appreciable emissions of styrene; in Quebec, more than 3000 workers work in this industry. A statistical analysis of styrene concentrations measured over a five-year period by the Institut de recherche en santé et en sécurité du travail (IRSST, Occupational Health and Safety Research Institute) reveals that for all of the main manufacturing sectors involved, between 40 percent and 78 percent of the results exceed the exposure standard of 50 ppm. This study evaluated the effectiveness of a ventilated table in controlling worker exposure to styrene and acetone in a shop that manufactures fiber-reinforced plastics parts. The evaluated local extraction system consists of a ventilated table with a surface area of 1.2 m x 1.2 m. During molding, the styrene emissions are exhausted through the ventilated table as well as through the slots in a lateral hood. Replacement air, introduced vertically through a supply air shower located above the worker, limits the diffusion of contaminants toward the worker's breathing zone. The reduction in worker exposure to styrene and acetone during hand lay-up molding was measured in the breathing zone for two sizes of molds. The results show that exhaust ventilation reduced the styrene concentrations by 91 percent and that the introduction of replacement air increased the efficiency of the ventilated table to 96 percent. The evaluation performed indicates that the ventilated table adequately controls worker exposure to styrene and acetone during the molding of small components.

Uranium in the Mayoworth area, Johnson County, Wyoming - a preliminary report

USGS Publications Warehouse

Love, J.D.

1954-01-01

The uranium mineral, metatyuyamunite, occurs in the basal limestone of the Sundance formation of late Jurassic age along the east flank of the Bighorn Mountains, about 2 miles southwest of the abandoned Mayoworth post office. This occurrence is of particular interest because it is the first uranium mineralization reported from a marine limestone in Wyoming. The discovery uranium claims were filed in July 1953, by J.S. Masek, Dan Oglesby, and Jack Emery of Casper, Wyo. Subsequent reconnaissance investigations have been made by private individuals and geologists of the U.S. Geological Survey and Atomic Energy Commission. The metatyuyamunite is concentrated in a hard gray oolitic limestone that forms the basal bed of the Sundance formation. A selected sample of limestone from a fresh face in the northernmost deposit known at the time of the field examination contained 0.70 percent equivalent uranium and 0.71 percent uranium. Eight samples of the limestone taken at the sample place by the Atomic Energy Commission contained from 0.007 to 0.22 percent uranium. A chip sample from the weathered outcrop at the top of this limestone half a mile to the southeast contained 0.17 percent equivalent uranium and 0.030 percent uranium. A dinosaur bone from the middle part of the Morrison formation contained 0.044 percent equivalent uranium and 0.004 percent uranium. metatyuyamunite forms a conspicuous yellow coating along fracture planes cutting the oolitic limestone and has also replaced many of the oolites within the solid limestone and has also replaced many of the oolites within the solid limestone even where fractures are not present. Many radioactive spots in the basal limestone of the Sundance formation were examined in a reconnaissance fashion along the outcrop for a distance of half a mile south of the initial discovery. Samples were taken for analysis only at the northern and southern margins of this interval. Outcrops farther north and south were not studied. There are not sufficient data to make even rough estimates of tonnage and grade of the occurrences. The extent of the limestone, the approximate boundaries of the area of above-normal radioactivity, and the possibilities of other radioactive zones have not been thoroughly investigated. Although dinosaur bones in the Morrison formation were radioactive wherever they were tested, no significant amount of radioactivity was observed in rocks adjacent to the bones.

Few studies have described rates of schizophrenia in a national sample of homicide perpetrators. This study aimed to describe this group's social and clinical characteristics, mental state features, offense details, and outcome in court. Analyses used a national clinical survey that collected data on people convicted of homicide in England and Wales (1996-1999). Data were collected for those with schizophrenia or other delusional disorders from psychiatric reports and questionnaires. Of the 1,594 people convicted of homicide, 85 (5 percent) had schizophrenia. Of the 57 people with schizophrenia for whom data were available, 32 (56 percent) had been ill for less than 12 months, and in the month before the offense, 32 (56 percent) had shown a change in the quality, intensity, or conviction of or emotional response to their delusional beliefs. Twenty-four (28 percent) had no previous contact with psychiatric services. Regular assessment of delusions may help to detect an increased risk of violence, including homicide. More intensive care should be available for patients with a history of schizophrenia and previous violence.

In Ethiopia, young people with disabilities (YPWD) are often marginalized and not recognized as being sexual, and only little is known about their sexual reproductive health (SRH) status. We therefore aimed to assess the SRH status and associated factors among 426 YPWD in Addis Ababa, Ethiopia. A cross-sectional survey was conducted in 2012. Data were collected by trained interviewers using a structured questionnaire. Fifty-two percent of YPWD ever had sexual intercourse. Seventy-five percent started sex between 15 and 19 years. Only 35% had used contraceptive during their first sexual encounter. Fifty-nine percent of the sexually experienced YPWD had multiple lifetime sexual partners; 19%, a casual sexual partner; and 21%, a commercial sexual partner. Only 48% consistently used condoms with their casual or commercial sexual partners. Twenty-four percent of the sexually experienced YPWD had a history of sexually transmitted infections. Our findings indicate that YPWD in Ethiopia are sexually active, but also highly involved in risky sexual practices. There is a need for in-depth research to better understand the determinants of risky sexual behavior and to propose preventive approaches.

Increasing physical activity among children is a potentially important public health intervention. Quantifying the economic and health effects of the intervention would help decision makers understand its impact and priority. Using a computational simulation model that we developed to represent all US children ages 8-11 years, we estimated that maintaining the current physical activity levels (only 31.9 percent of children get twenty-five minutes of high-calorie-burning physical activity three times a week) would result each year in a net present value of $1.1 trillion in direct medical costs and $1.7 trillion in lost productivity over the course of their lifetimes. If 50 percent of children would exercise, the number of obese and overweight youth would decrease by 4.18 percent, averting $8.1 billion in direct medical costs and $13.8 billion in lost productivity. Increasing the proportion of children who exercised to 75 percent would avert $16.6 billion and $23.6 billion, respectively. Project HOPE—The People-to-People Health Foundation, Inc.

Energetics and sugar-feeding of field-collected anopheline females.

1997-06-01

We studied the relationship between nutritional reserves and blood-feeding and sugar-feeding of Anopheles freeborni (Diptera: Culicidae) females in the field. In particular we determined whether (1) females feed on nectar before maturing eggs and initiating host-seeking and (2) the energy reserves of host-seeking females differ from those of non-fed resting females. Twenty-three percent of host-seeking females and 94 percent of gravid females were positive for nectar sugars (containing > 20 micrograms of fructose) versus 55 percent of empty (no blood or eggs) females collected in the morning and 36 percent of empty females collected in the evening. In addition, gravid females contained significantly more calories of nectar than empty, blood-fed, or partially blood-fed females collected in the morning. When the energy reserves of host-seeking and resting females were compared, no differences were found in lipid, trehalose, or glycogen. However, empty females collected in the evening contained more glycogen than empty females collected in the morning. We conclude that gravid females frequently feed on nectar and that fructose is metabolized into glycogen during the day.

Fibromyalgia (FM) is a condition characterized by widespread pain, estimated to affect 2.4% of the Spanish population. Nowadays, there are no consistent epidemiological studies on the actual impact of the disease on work and family of these patients in a representative manner; therefore, the purpose of the study is to analyze the impact on family, employment and social environment in a representative sample of patients with FM attending Primary Public Care Centers in Spain. We carried out an epidemiological study, with a probability sampling procedure, stratified, relative to the municipality size and the number of health centres, seeking territorial representation. The survey was conducted using a self-administered structured questionnaire. A sample of 325 patients with FM was studied in 35 Primary Health Care Centers (PHCCs). The sample is composed of 96.6% of women, 51.9 (8) years of mean (standard deviation- sd) age. Ninety-three percent of the patients have worked throughout their life. Mean (sd) age onset of symptoms was 37 (11) years and diagnosis of FM was established 6.6 (8) years later. Family Environment: Fifty-nine percent of patients have difficulties with their partner. Forty-four percent of the patients report to be fairly or totally dependent on a family member in household chores. The household income decreased a mean (sd) of 708 (504) Euros/month in 65% of the patients. In 81% of the patients, there was an increase in extra expenses related to the disease with a mean (sd) of 230 (192) Euros/month. Working environment: At the moment of the study, 45% of the patients had work activity (34% were working and 11% were at sick leave), 13% were unemployed seeking job and 42% were not in the labor force. Twenty-three percent of patients had some degree of permanent work disability pension. Social Environment: The degree of satisfaction with health care professionals was low and twenty-six percent of the patients were members of specific patients associations. This study finds that people with FM who visit PHCCs of Spain experience a high impact on families and employment with heavy loss of ability to work.

Direct-To-Consumer Telehealth May Increase Access To Care But Does Not Decrease Spending.

PubMed

Ashwood, J Scott; Mehrotra, Ateev; Cowling, David; Uscher-Pines, Lori

2017-03-01

The use of direct-to-consumer telehealth, in which a patient has access to a physician via telephone or videoconferencing, is growing rapidly. A key attraction of this type of telehealth for health plans and employers is the potential savings involved in replacing physician office and emergency department visits with less expensive virtual visits. However, increased convenience may tap into unmet demand for health care, and new utilization may increase overall health care spending. We used commercial claims data on over 300,000 patients from three years (2011-13) to explore patterns of utilization and spending for acute respiratory illnesses. We estimated that 12 percent of direct-to-consumer telehealth visits replaced visits to other providers, and 88 percent represented new utilization. Net annual spending on acute respiratory illness increased $45 per telehealth user. Direct-to-consumer telehealth may increase access by making care more convenient for certain patients, but it may also increase utilization and health care spending.

An equitable way to pay for universal coverage.

PubMed

Rasell, E

1999-01-01

This article describes a way to finance universal health care coverage that preserves much of the current financing system and replaces funds obtained from regressive sources with revenue from more progressive ones. New funding would be needed for 24 percent of health expenditures and would be raised through an increase in the federal personal income tax. Premiums are eliminated since their cost is the same to everyone regardless of income. Cost sharing and out-of-pocket spending for medically necessary services are also abolished. In a more equitably financed system, employers would pay a new payroll tax that raised the same amount of money they currently spend for employee health insurance premiums; this would require a payroll tax of about 7 percent. Revenue from an increase in federal personal income taxes would replace household out-of-pocket expenditures for medically necessary services and payments for insurance premiums. For the average, middle-income family, the tax increase would total $731 in 1998. In exchange for the tax increase, no American or American employer would need to buy health insurance or face out-of-pocket charges for any medically indicated health care.

Grote, Lauren; Myers, Melanie; Lovell, Anne; Saal, Howard; Sund, Kristen Lipscomb

2014-01-01

SNP microarrays are capable of detecting regions of homozygosity (ROH) which can suggest parental relatedness. This study was designed to describe pre- and post-test counseling practices of genetics professionals regarding ROH, explore perceived comfort and ethical concerns in the follow-up of such results, demonstrate awareness of laws surrounding duty to report consanguinity and incest, and allow respondents to share their personal experiences with results suggesting a parental relationship. A 35 question survey was administered to 240 genetic counselors and geneticists who had ordered or counseled for SNP microarray. The results are presented using descriptive statistics. There was variation in both pre- and post-test counseling practices of genetics professionals. Twenty-five percent of respondents reported pre-test counseling that ROH can indicate parental relatedness. The most commonly reported ethical concern was disclosure of findings suggesting parental relatedness to parents of the patient; only 48.4% reported disclosing parental relatedness when indicated. Fifty-seven percent felt comfortable receiving results suggesting parental consanguinity while 17% felt comfortable receiving results suggesting parental incest. Twenty percent of respondents were extremely/moderately familiar with the laws about duty to report incest. Personal experiences in post-test counseling included both parental acknowledgement and denial of relatedness. This study highlights the differences in genetics professionals' pre- and post-test counseling practices, comfort, and experiences surrounding parental relatedness suggested by SNP microarray results. It identifies a need for professional organizations to offer guidance to genetics professionals about how to respond to and counsel for molecular results suggesting parental consanguinity or incest. © 2013 Wiley Periodicals, Inc.

The purpose of this article is to analyze the sonographic appearance of nodular Hashimoto thyroiditis. As part of an ongoing multiinstitutional study, patients who underwent ultrasound examination and fine-needle aspiration of one or more thyroid nodules were analyzed for multiple predetermined sonographic features. Patients completed a questionnaire, including information about thyroid function and thyroid medication. Patients (n = 61) with fine-needle aspiration cytologic results consistent with nodular Hashimoto thyroiditis (n = 64) were included in the study. The mean (+/- SD) diameter of nodular Hashimoto thyroiditis was 15 +/- 7.33 mm. Nodular Hashimoto thyroiditis occurred as a solitary nodule in 36% (23/64) of cases and in the setting of five or more nodules in 23% (15/64) of cases. Fifty-five percent (35/64) of the cases of nodular Hashimoto thyroiditis occurred within a sonographic background of diffuse Hashimoto thyroiditis, and 45% (29/64) of cases occurred within normal thyroid parenchyma. The sonographic appearance was extremely variable. It was most commonly solid (69% [42/61] of cases) and hypoechoic (47% [27/58] of cases). Twenty percent (13/64) of nodules had calcifications (seven with nonspecific bright reflectors, four with macrocalcifications, and three eggshell), and 5% (3/64) of nodules had colloid. Twenty-seven percent (17/64) of nodules had a hypoechoic halo. The margins were well defined in 60% (36/60) and ill defined in 40% (24/60) of nodules. On Doppler analysis, 35% (22/62) of nodules were hypervascular, 42% (26/62) were isovascular or hypovascular, and 23% (14/62) were avascular. The sonographic features and vascularity of nodular Hashimoto thyroiditis were extremely variable.

1997-07-01

Our aim was to prospectively evaluate pelvic floor retraining (PFR) in improving symptomatic fecal incontinence. PFR was used to treat 30 patients with fecal incontinence (28 women; age range, 29-85 (median, 68) years). PFR was performed by a physiotherapist in the outpatient department according to a strict protocol and included biofeedback using an anal plug electromyometer. Manometry (24 patients), pudendal nerve terminal motor latency (PNTML, 16 patients), and anal ultrasound (14 patients) were done before commencing therapy. Independent assessment of symptoms was done at the commencement of therapy, at 6 weeks, and at 6 and 12 months posttherapy. Twenty patients (67 percent) had improved incontinence scores, with eight patients (27 percent) being completely or nearly free of symptoms. Of 28 patients followed up longer than six months, 14 achieved a 25 percent or greater improvement at six weeks, which was sustained in all cases. Fourteen had an initial improvement of less than 25 percent, with only four (29 percent) showing later improvement (P < 0.0001). There was no relationship between results of the therapy and patient age, initial severity of symptoms, etiology of incontinence, and results of anal manometry, PNTML, and anal ultrasound. PFR is a physical therapy that should be considered as the initial treatment in patients with fecal incontinence. An improvement can be expected in up to 67 percent of patients. Initial good results can predict overall outcome.

Obesity, a multifactorial disease caused by the interaction of genetic factors with the environment, is largely polygenic. A few mutations in these genes, such as in the leptin receptor (LEPR) gene and melanocortin 4 receptor (MC4R) gene, have been identified as causes of monogenic obesity. We sequenced the complete MC4R coding region, the region of the proopiomelanocortin gene (POMC) encoding the alpha melanocyte-stimulating hormone, and the leptin-binding domain of LEPR in 469 severely obese white subjects (370 women and 99 men; mean [+/-SE] age, 41.0+/-0.5 years; body-mass index [the weight in kilograms divided by the square of the height in meters], 44.1+/-2.0). Fifteen women and 10 men without a history of dieting or a family history of obesity served as normal-weight controls (age, 47.7+/-2.0 years; body-mass index, 21.6+/-0.4). Detailed phenotypic data, including information on body fat, resting energy expenditure, diet-induced thermogenesis, serum concentrations of leptin, and eating behavior, were collected. Twenty-four obese subjects (5.1 percent) and one control subject (4 percent) had MC4R mutations, including five novel variants. Twenty of the 24 obese subjects with an MC4R mutation were matched for age, sex, and body-mass index with 120 of the 445 obese subjects without an MC4R mutation. All mutation carriers reported binge eating, as compared with 14.2 percent of obese subjects without mutations (P<0.001) and 0 percent of the normal-weight subjects without mutations. The prevalence of binge eating was similar among carriers of mutations in the leptin-binding domain of LEPR and noncarriers. No mutations were found in the region of POMC encoding alpha melanocyte-stimulating hormone. Binge eating is a major phenotypic characteristic of subjects with a mutation in MC4R, a candidate gene for the control of eating behavior. Copyright 2003 Massachusetts Medical Society

Use of HIV postexposure prophylaxis by dental health care personnel: an overview and updated recommendations.

PubMed

Cleveland, Jennifer L; Barker, Laurie; Gooch, Barbara F; Beltrami, Elise M; Cardo, Denise

2002-12-01

The authors conducted a study on the use of postexposure prophylaxis, or PEP, for exposure to human immunodeficiency virus, or HIV, among dental health care personnel, or DHCP, enrolled in a surveillance system established by the Centers for Disease Control and Prevention, or CDC. They also discuss updated U.S. Public Health Service, or USPHS, recommendations for managing occupational exposures to HIV, as well as considerations for dentistry. The authors analyzed occupational exposures reported by DHCP to the CDC to describe characteristics of the exposure (for example, type and severity), the source patient's HIV status and use of PEP. From June 1995 through August 2001, DHCP reported 208 exposures--199 percutaneous injuries, six mucous membrane exposures and three skin exposures--to the CDC. One-third of these percutaneous injuries were caused by small-bore hollow syringe needles, and most (66 percent) were moderate in depth. Nearly half the devices involved (46 percent) were visibly bloody at the time of injury. Per the criteria described in USPHS guidelines, one-half of the injuries were categorized as "less severe." Twenty-four (13 percent) known source patients were HIV-positive; 14 had symptomatic HIV infection or a high viral load. In this study, three in four DHCP exposed to an HIV-positive source warranted a three-drug PEP regimen. Twenty-nine (24 percent) DHCP exposed to a source patient who subsequently was found to be HIV-negative took PEP; six took PEP for five to 29 days. No exposures resulted in HIV infection. Findings of this study are consistent with earlier reports indicating that the risk of HIV transmission in dental settings is low. Strategies such as rapid HIV testing of source patients and follow-up counseling may reduce unnecessary use of PEP. Dental practices should develop comprehensive, written programs for preventing and managing occupational exposures to blood.

Chapter 16: Retrocommissioning Evaluation Protocol. The Uniform Methods Project: Methods for Determining Energy Efficiency Savings for Specific Measures

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kurnik, Charles W.; Tiessen, Alex

Retrocommissioning (RCx) is a systematic process for optimizing energy performance in existing buildings. It specifically focuses on improving the control of energy-using equipment (e.g., heating, ventilation, and air conditioning [HVAC] equipment and lighting) and typically does not involve equipment replacement. Field results have shown proper RCx can achieve energy savings ranging from 5 percent to 20 percent, with a typical payback of two years or less (Thorne 2003). The method presented in this protocol provides direction regarding: (1) how to account for each measure's specific characteristics and (2) how to choose the most appropriate savings verification approach.

Away Rotations and Matching in Integrated Plastic Surgery Residency: Applicant and Program Director Perspectives.

PubMed

Drolet, Brian C; Brower, Jonathan P; Lifchez, Scott D; Janis, Jeffrey E; Liu, Paul Y

2016-04-01

Although nearly all medical students pursuing integrated plastic surgery residency participate in elective rotations away from their home medical school, the value and costs of these "away" rotations have not been well studied. The authors surveyed all integrated plastic surgery program directors and all applicants in the 2015 National Residency Matching Program. Forty-two program directors and 149 applicants (64 percent and 70 percent response rate, respectively) completed the survey. Applicants reported 13.7 weeks spent on plastic surgery rotations during medical school, including a mean of 9.2 weeks on away rotations. Average reported cost for away rotations was $3591 per applicant. Both applicants and program directors most commonly reported "making a good impression" (44.6 percent and 36.6 percent, respectively) or finding a "good-fit" program (27.7 percent and 48.8 percent, respectively) as the primary goal for away rotations. Almost all applicants (91.1 percent) believed an away rotation made them more competitive for matching to a program at which they rotated. Program directors ranked a strong away rotation performance as the most important residency selection criterion. Twenty-seven percent of postgraduate year-1 positions were filled by an away rotatorm and an additional 17 percent were filled by a home medical student. Away rotations appear to be mutually beneficial for applicants and programs in helping to establish a good fit between students and training programs through an extended interaction with the students, residents, and faculty. In addition, making a good impression on a senior elective rotation (home or away) may improve an applicant's chance of matching to a residency program.

Implementing tobacco use treatment guidelines in public health dental clinics in New York City.

2011-04-01

In this study we evaluated the effect of a multicomponent intervention to implement the Public Health Service (PHS) guideline Treating Tobacco Use and Dependence in six randomly selected dental clinics in New York University's College of Dentistry. The main outcome measure-provider adherence to tobacco use treatment guidelines-was assessed by auditing a random selection of patient charts pre (698) and post (641) intervention. The intervention components included a chart reminder and referral system, free nicotine replacement therapy (NRT), and provider training and feedback. The results showed that rates of screening for tobacco use did not change between pre and post test chart audits. However, providers were significantly more likely to offer advice (28.4 percent pre, 49 percent post), assess readiness to quit (17.8 percent pre, 29.9 percent post), and offer assistance (6.5 percent pre and 15.6 percent post) in the post test period. Increases in NRT distribution were associated with booster training sessions but declined in the time periods between those trainings. Research is needed to further define sustainable strategies for implementing tobacco use treatment in dental clinics. The results of this study suggest the feasibility and effectiveness of using a tailored multicomponent approach to implement tobacco use treatment guidelines in dental clinics.

Aware that constituent support is essential to any educational endeavor, the AOL Time Warner Foundation (now the Time Warner Foundation), in conjunction with two respected national research firms, measured Americans' attitudes toward the implementation of twenty-first century skills. The foundation's national research survey was intended to explore public perceptions of the need for changes in the educational system, in school and after school, with respect to the teaching of twenty-first century skills. The author summarizes the findings of the survey, which were released by the foundation in June 2003. One thousand adults were surveyed by telephone, including African Americans, Latinos, teachers, and business executives. In general, the survey found that Americans believe today's students need a "basics-plus" education, meaning communication, technology, and critical thinking skills in addition to the traditional basics of reading, writing, and math. In fact, 92 percent of respondents stated that students today need different skills from those of ten to twenty years ago. Also, after-school programs were found to be an appropriate vehicle to teach these skills. Furthermore, the survey explored how well the public perceives schools to be preparing youth for the workforce and postsecondary education, which twenty-first century skills are seen as being taught effectively, and the level of need for after-school and summer programs. The survey results provide conclusive evidence of national support for basics-plus education. Thus, a clear opportunity exists to build momentum for a new model of education for the twenty-first century.

Natural fine aggregate materials are commonly used in development and commercial construction in Malaysia. In fact, concrete production was increased as linear with the growing Malaysia economy. However, an issue was production of concrete was to locate adequate sources of natural fine aggregates. There lot of studies have been conducted in order to replace the fine aggregate in which natural fine aggregate replace with the waste material in concrete preparation. Therefore, this study aims to utilize the Recycled Concrete Aggregate (RCA) and ceramic waste which has great potential to replace the natural aggregate in concrete mix with different type of method, admixture, and parameters. This research were focused on compressive strength and water absorption test to determine the optimum mix ratio of concrete mix. The concrete aggregate was chosen due to improvement capillary bonding mechanisms and ceramic presented similar strength compared to the conventional concrete using natural aggregate. Percent of replacement have been used in this study was at 25%, 35% and 45% of the RCA and 5%, 10% and 15% for ceramic, respectively. Furthermore, this research was conduct to find the optimum percentage of aggregate replacement, using water-cement ratio of 0.55 with concrete grade 25/30. The best percentage of replacement was the RCA35% C15% with the compressive strength of 34.72 MPa and the water absorption was satisfied.

1989-01-01

A study was made to determine the potential speed improvements and other benefits resulting from the application of the joined wing concept to tiltrotor aircraft. Using the XV-15 as a baseline, the effect of replacing the cantilever wing by a joined-wing pair was studied. The baseline XV-15 cantilever wing has a thickness/chord ratio of 23 percent. It was found that this wing could be replaced by a joined-wing pair of the same span and total area employing airfoils of 12 percent thickness/chord ratio. The joined wing meets the same static strength requirements as the cantilever wing, but increases the limiting Mach Number of the aircraft from M=0.575 to M=0.75, equivalent to an increase of over 100 knots in maximum speed. The joined wing configuration studied is lighter than the cantilever and has approximately 11 percent less wing drag in cruise. Its flutter speed of 245 knots EAS is not high enough to allow the potential Mach number improvement to be attained at low altitude. The flutter speed can be raised either by employing rotors which can be stopped and folded in flight at speeds below 245 knots EAS, or by modifying the airframe to reduce adverse coupling with the rotor dynamics. Several modifications of wing geometry and nacelle mass distribution were investigated, but none produced a flutter speed above 260 knots EAS. It was concluded that additional research is required to achieve a more complete understanding of the mechanism of rotor/wing coupling.

Local infiltration analgesia versus continuous interscalene brachial plexus block for shoulder replacement pain: a randomized clinical trial.

PubMed

Shoulder replacement involves significant post-operative pain, which is often managed by continuous interscalene brachial plexus block. Catheter displacement and complications limit the beneficial effect of the block. Local infiltration analgesia (LIA) has provided good results in knee replacement. We aimed to assess the effectiveness of LIA for pain after shoulder replacement. Patients scheduled for primary shoulder replacement under general anaesthesia were randomized to receive either local infiltration analgesia (LIA) (150 ml ropivacaine 0.2 % with epinephrine intra-operatively) or interscalene brachial plexus catheter (ISC) (ropivacaine 0.75 %, 7 ml bolus followed by 48-h 5 ml/h infusion). The primary outcome was opioid consumption during the first 24 post-operative hours. Secondary outcomes were pain ratings, supplementary analgesics, and side effects for 3 days, and complications until 3 months after surgery. Data were analysed for 61 patients (LIA 30, ISC 31). Twenty-four-hour opioid consumption was higher in the LIA group compared with the ISC group: median (IQR) 95 mg (70-150 mg) versus 40 mg (8-76 mg) (P = 0.0001). No significant difference in opioid consumption was found between groups during the following 3 days. The LIA group had higher pain scores at 0, 2, 4, and 8 h. Two patients in the ISC group had long-lasting complications. The LIA technique cannot be recommended for shoulder replacement unless substantially modified. Occurrence of inadequate analgesia and complications following interscalene brachial plexus block prompt further studies into pain management after shoulder replacement.

A cross-sectional study of pulmonary function in autobody repair workers.

1991-01-01

This study evaluated pulmonary function in workers from 39 autobody repair shops. Based on 152 White male workers with known smoking status, the mean percent predicted FEV1, FVC, and FEV1/FVC were 93.6, 96.8, and 96.6, respectively. Twenty-three percent of workers had a FEV1/FVC ratio less than the fifth percentile. Isocyanate levels ranged from nondetectable to 0.06 parts per million (STEL = 0.02 ppm). No shop had an adequate respiratory protection program. We concluded that there was an increase in abnormal pulmonary function in autobody workers. Three recommendations were made to shop owners: functional paint booths should be maintained, respiratory protection programs should be developed, and isocyanate-free paints should be used.

Slaby, J. G.; Siegel, B. L.

1973-01-01

The examination of 27 fuel pins irradiated for up to 13,000 hours at 990 C is described. The fuel pin clad was a tantalum alloy with uranium nitride as the nuclear fuel. Two nominal fuel pin diameters were tested with a maximum burnup of 2.34 atom percent. Twenty-two fuel pins were tested for fission gas leaks; thirteen pins leaked. Clad ductility tests indicated clad embrittlement. The embrittlement is attributed to hydrogen from an n,p reaction in the fuel. Fuel swelling was burnup dependent, and the amount of fission gas release was low, generally less than 0.5 percent. No incompatibilities between fuel, liner, and clad were in evidence.

A flooded-starved design for nickel-cadmium cells

NASA Technical Reports Server (NTRS)

Thaller, L. H.

1986-01-01

A somewhat analogous situation among groupings of alkaline fuel cells is described where the stochastic aspects were much more accurately documented and then it was illustrated how this problem was eliminated using straight forward principles of pore size engineering. This is followed by a suggested method of adapting these same design principles to nickel-cadmium cells. It must be kept in mind that when cells are cycled to typically twenty percent depth of discharge that eighty percent of the weight of the cell is simply dead weight. Some of this dead weight might be put to better use by trading it for a scheme that would increase the time during which the cell would be working more closely to its optimum set of operating parameters.

Kistan, D; Booysen, M; Alexander, G; Madiba, T E

2017-06-01

Mitral valve replacement is the procedure of choice in patients with severe mitral valve disease. However, these patients are surviving longer and are thus at an increased risk of prosthesis failure or valve-related complications. Study setting: Inkosi Albert Luthuli Central Hospital, a tertiary referral Hospital in Durban. Study population: All patients undergoing redo mechanical mitral valve replacement surgery between January 2005 and December 2014. Study design: Retrospective analysis of patients undergoing redo mitral valve replacement. Patients were identified from theatre record books, their files were electronically accessed and pertinent information extracted onto a data capture sheet. Information documented included demographics, duration to failure, INR, Albumin, HIV status, clinical findings and outcome. The data was stored on an Excel datasheet. Fifty-eight patients were documented (mean age 32 ± 15.81 years; M:F 1:3). Ten patients (17%) were HIV positive (median CD4 count 478). Mean duration between first surgery and redo was 8.8 years. Thirty-five patients (60%) had no co-morbidities. Presenting features at redo surgery were congestive cardiac failure (27), chest pain (11) and palpitations (17). Mean preoperative Ejection Fraction was 51.65 %. Twenty-nine patients (55%) had emergency redo surgery. Twenty-two patients (75%) had acute prosthetic valve thrombosis. Thirty-two patients had tricuspid regurgitation. Original pathology was documented in 23 patients (40%) as Rheumatic valve disease. Prosthetic valve thrombosis was documented in 31 patients (54%). The most commonly used valve was the On-X. Mean presenting INR was 1.96 + 1.2 and mean presenting serum albumin was 36.7 + 7.8 g/l. Forty-one patients (71%) were found to be compliant to Warfarin therapy prior to redo surgery. Mean ICU stay was 6 +9 days. Two patients died postoperatively. Mean followup was 32 + 26.6 months. Twelve patients (20.7%) developed postoperative complications. Patients were younger than world literature suggests. Rheumatic heart disease was the common underlying pathology. Prosthetic valve thrombosis was common. More than half had emergency surgery. Mortality rate was negligible.

Growing a Colony from an Outpost - The Colonization of Mars in the Twenty-Second Century

NASA Astrophysics Data System (ADS)

Halyard, R. J.

Near the end of the Twenty-first Century there may be one or more permanent outposts on Mars; these outposts will recycle their water and atmosphere and remain permanently staffed. The Earth will provide crew rotation plus food supplies and replacement equipment approximately every one and one-half years. Assuming that the permanent outposts are located near deposits of frozen water and necessary minerals, the potential exists of expanding these outposts to a small, self-sufficient colony. Additional equipment, structures and personnel plus changes in operations will be required to make the expansion to a colony possible. Because many variables and assumptions exist in the determination of the additional hardware, the resulting proposed colony design is very tentative and provides only as an initial estimate of the effort required. However if the assumptions are met and the equipment indicated developed, it should definitely be possible to establish a Mars colony in the early Twenty-second Century.

2018-05-01

The structural and magnetic properties of La1-yTbyFe11.5Si1.5 compounds have been investigated. The substituted 5 percent of Tb has remarkably increased the maximum entropy change (-ΔSM) to a value of 25.2 J/kg·K. However, a further increase of Tb leads to a monotonous decrease in the entropy change, mainly due to phase separation. The Tb substitution also can lower the thermal and magnetic hysteresis loss of the system. Another feature of this replacement is that, with Tb content higher than 10 percent, the Curie temperature (TC) starts to increase and reaches 197 K when 30 percent of La is substituted. These results indicate that La1-yTbyFe11.5Si1.5 may be a promising candidate for magnetic refrigeration material in certain temperature range.

How health care reform can lower the costs of insurance administration.

2009-07-01

The United States leads all industrialized countries in the share of national health care expenditures devoted to insurance administration. The U.S. share is over 30 percent greater than Germany's and more than three times that of Japan. This issue brief examines the sources of administrative costs and describes how a private-public approach to health care reform--with the central feature of a national insurance exchange (largely replacing the present individual and small-group markets)--could substantially lower such costs. In three variations on that approach, estimated administrative costs would fall from 12.7 percent of claims to an average of 9.4 percent. Savings--as much as $265 billion over 2010-2020--would be realized through less marketing and underwriting, reduced costs of claims administration, less time spent negotiating provider payment rates, and fewer or standardized commissions to insurance brokers.

Pre-operative interventions (non-surgical and non-pharmacological) for patients with hip or knee osteoarthritis awaiting joint replacement surgery--a systematic review and meta-analysis.

PubMed

Wallis, Jason A; Taylor, Nicholas F

2011-12-01

To determine if pre-operative interventions for hip and knee osteoarthritis provide benefit before and after joint replacement. Systematic review with meta-analysis of randomised controlled trials (RCTs) of pre-operative interventions for people with hip or knee osteoarthritis awaiting joint replacement surgery. Standardised mean differences (SMD) were calculated for pain, musculoskeletal impairment, activity limitation, quality of life, and health service utilisation (length of stay and discharge destination). The GRADE approach was used to determine the quality of the evidence. Twenty-three RCTs involving 1461 participants awaiting hip or knee replacement surgery were identified. Meta-analysis provided moderate quality evidence that pre-operative exercise interventions for knee osteoarthritis reduced pain prior to knee replacement surgery (SMD (95% CI)=0.43 [0.13, 0.73]). None of the other meta-analyses investigating pre-operative interventions for knee osteoarthritis demonstrated any effect. Meta-analyses provided low to moderate quality evidence that exercise interventions for hip osteoarthritis reduced pain (SMD (95% CI)=0.52 [0.04, 1.01]) and improved activity (SMD (95% CI)=0.47 [0.11, 0.83]) prior to hip replacement surgery. Meta-analyses provided low quality evidence that exercise with education programs improved activity after hip replacement with reduced time to reach functional milestones during hospital stay (e.g., SMD (95% CI)=0.50 [0.10, 0.90] for first day walking). Low to moderate evidence from mostly small RCTs demonstrated that pre-operative interventions, particularly exercise, reduce pain for patients with hip and knee osteoarthritis prior to joint replacement, and exercise with education programs may improve activity after hip replacement.

Relationship of milking rate to somatic cell count.

PubMed

Brown, C A; Rischette, S J; Schultz, L H

1986-03-01

Information on milking rate, monthly bucket somatic cell counts, mastitis treatment, and milk production was obtained from 284 lactations of Holstein cows separated into three lactation groups. Significant correlations between somatic cell count (linear score) and other parameters included production in lactation 1 (-.185), production in lactation 2 (-.267), and percent 2-min milk in lactation 2 (.251). Somatic cell count tended to increase with maximum milking rate in all lactations, but correlations were not statistically significant. Twenty-nine percent of cows with milking rate measurements were treated for clinical mastitis. Treated cows in each lactation group produced less milk than untreated cows. In the second and third lactation groups, treated cows had a shorter total milking time and a higher percent 2-min milk than untreated cows, but differences were not statistically significant. Overall, the data support the concept that faster milking cows tend to have higher cell counts and more mastitis treatments, particularly beyond first lactation. However, the magnitude of the relationship was small.

Cannabis (Cannabis sativa or C. indica) agriculture and the environment: a systematic, spatially-explicit survey and potential impacts

NASA Astrophysics Data System (ADS)

Butsic, Van; Brenner, Jacob C.

2016-04-01

Cannabis agriculture is a multi-billion dollar industry in the United States that is changing rapidly with policy liberalization. Anecdotal observations fuel speculation about associated environmental impacts, and there is an urgent need for systematic empirical research. An example from Humboldt County California, a principal cannabis-producing region, involved digitizing 4428 grow sites in 60 watersheds with Google Earth imagery. Grows were clustered, suggesting disproportionate impacts in ecologically important locales. Sixty-eight percent of grows were >500 m from developed roads, suggesting risk of landscape fragmentation. Twenty-two percent were on steep slopes, suggesting risk of erosion, sedimentation, and landslides. Five percent were <100 m from threatened fish habitat, and the estimated 297 954 plants would consume an estimated 700 000 m3 of water, suggesting risk of stream impacts. The extent and magnitude of cannabis agriculture documented in our study demands that it be regulated and researched on par with conventional agriculture.

Explaining Participation: An Explanatory History of Select Gender Patterns in Undergraduate STEM

NASA Astrophysics Data System (ADS)

Mastroianni, Michael Pasquale

This explanatory study examines three focal periods in undergraduate STEM as related to the gender gap. Social, economic, and more general historical data are used to develop a clear and powerful explanation of baccalaureate trends in biology and engineering. Specifically, historical accounts are offered for 1) a ten-year period in undergraduate biology in which the number of baccalaureates awarded to men decreased 44 percent, while the number of baccalaureates awarded to women decreased one percent; 2) the start of a twenty-year period in which the number of bachelor's degrees awarded in the biological sciences increased 150 percent---from 36,068 degrees in 1989, to 90,003 bachelor's degrees in 2011; and 3) a ten year period in undergraduate engineering where female graduation rates septupled---this ten-year time period is the only instance of meaningful and noteworthy growth for women in undergraduate engineering over the past half century. Findings from each history reveal a common narrative underlying baccalaureate trends. Implications for undergraduate STEM are discussed.

Measure the frequency of physical and sexual abuse in a sample of reproductive aged women displaced by Hurricane Katrina, and compare those experiences to the year before Hurricane Katrina. Sixty-six English-speaking women aged 18-49 years residing in Louisiana Federal Emergency Management Agency (FEMA) housing were screened for physical and sexual abuse seven to nine months after Hurricane Katrina, using modified 30x7 cluster sampling methodology. Twenty-three percent (95% confidence interval [CI], 14, 34%) of women reported being hit or verbally threatened since Hurricane Katrina. Abuse had increased for 33% (95% CI, 13, 63%) and decreased for 13% (95% CI, 4, 37%) of women. Twenty percent (95% CI, 6, 51%) of abused women were with a new partner, while 13% (95% CI, 4, 39%) reported new abuse with the same partner. Four women reported sexual abuse since Hurricane Katrina. Compared to before the storm, the frequency of sexual abuse was the same for two women, and one reported new abuse with the same partner. Physical abuse was not uncommon among displaced women following Hurricane Katrina. Increasing and new abuse were the most commonly reported experiences. Violence against women should not be overlooked as a continued, and perhaps escalating, occurrence requiring attention following displacement after disasters of such magnitude as Hurricane Katrina.

Recent studies have demonstrated increasing rates of financial toxicities and emotional distress related to cancer treatment. This study assessed and characterized the relationships among financial distress, emotional symptoms, and overall distress in patients with cancer. A cross-sectional sample of patients with cancer who visited our outpatient medical oncology and psychiatry clinics completed a pen-and-paper survey. The survey assessed demographics; cost concerns; and financial, emotional, and overall distress. One hundred twenty insured patients completed the survey. Sixty-five percent reported clinically significant overall distress scores, with the same percentage reporting at least one emotional problem (worry, anxiety, depression, etc). Twenty-nine percent scored in the range of high to overwhelming financial distress. By using structural equation modeling, we found that financial distress was associated with overall distress. This association was both direct (accounting for 76% of the effect) and indirect (accounting for 24% of the effect) via mediation by emotional distress. This cohort of patients with cancer reported significant levels of emotional distress, financial distress, and overall distress. These factors were interrelated, with both financial and emotional distress contributing to overall distress. Interventions targeted at alleviating financial distress may help to decrease levels of overall distress. Copyright © 2016 by American Society of Clinical Oncology.

This study investigated the presence and antibiotic resistance of Salmonella spp. in a shrimp farming environment in Northeast Region of Brazil. Samples of water and sediments from two farms rearing freshwater-acclimated Litopenaeus vannamei were examined for the presence of Salmonella. Afterwards, Salmonella isolates were serotyped, the antimicrobial resistance was determined by a disk diffusion method, and the plasmid curing was performed for resistant isolates. A total of 30 (16.12%) of the 186 isolates were confirmed to be Salmonella spp., belonging to five serovars: S. serovar Saintpaul, S. serovar Infantis, S. serovar Panama, S. serovar Madelia, and S. serovar Braenderup, along with 2 subspecies: S. enterica serovar houtenae and S. enterica serovar enterica. About twenty-three percent of the isolates were resistant to at least one antibiotic, and twenty percent were resistant to at least two antibiotics. Three strains isolated from water samples (pond and inlet canal) exhibited multiresistance to ampicillin, tetracycline, oxytetracycline, and nitrofurantoin. One of them had a plasmid with genes conferring resistance to nitrofurantoin and ampicillin. The incidence of bacteria pathogenic to humans in a shrimp farming environment, as well as their drug-resistance pattern revealed in this study, emphasizes the need for a more rigorous attention to this area.

The potential ecological impact of excess streambed sediment resulting from forest management activities is a persistent concern for land managers. This study examined the relationship between streambed sediment, along with other site- and reach-scale abiotic factors, and benthic macroinvertebrate community structure in a 272 km2 basin in the Colorado Front Range. Physical habitat parameters and invertebrates were sampled in late summer at 68 sites located in sixteen stream reaches. Invertebrate data were used to formulate twenty indices of community structure. Multiple regression identified site-level substrate particle size as the most important predictor of six indices, including total density (R2 = 0.22), biomass (R2 = 0.17), and taxa richness (R2 = 0.32). All of the remaining fourteen indices were most strongly predicted by reach-level variables, including discharge (percent shredders, R2 = 0.24; Plecoptera density, R2 = 0.29), and elevation (percent collector-filterers, R2 = 0.28; Trichoptera density, R2 = 0.37). Although the sites represented a wide range of substrate composition and embeddedness, no physical variable associated with fine sediment appeared as a strong predictor of any of the twenty indices. Thus, sediment is not among the most important factors associated with site-to-site variability of benthic community structure in this relatively pristine watershed.

Purpose: Recent studies have demonstrated increasing rates of financial toxicities and emotional distress related to cancer treatment. This study assessed and characterized the relationships among financial distress, emotional symptoms, and overall distress in patients with cancer. Methods: A cross-sectional sample of patients with cancer who visited our outpatient medical oncology and psychiatry clinics completed a pen-and-paper survey. The survey assessed demographics; cost concerns; and financial, emotional, and overall distress. Results: One hundred twenty insured patients completed the survey. Sixty-five percent reported clinically significant overall distress scores, with the same percentage reporting at least one emotional problem (worry, anxiety, depression, etc). Twenty-nine percent scored in the range of high to overwhelming financial distress. By using structural equation modeling, we found that financial distress was associated with overall distress. This association was both direct (accounting for 76% of the effect) and indirect (accounting for 24% of the effect) via mediation by emotional distress. Conclusion: This cohort of patients with cancer reported significant levels of emotional distress, financial distress, and overall distress. These factors were interrelated, with both financial and emotional distress contributing to overall distress. Interventions targeted at alleviating financial distress may help to decrease levels of overall distress. PMID:27328795

Research has shown that many healthcare professionals have problems with guidelines as they would prefer to be given all relevant information relevant to decision-making rather than being told what they should do. This study assesses doctors' judgement of the validity, relevance, clarity and usability of the Italian translation of Clinical Evidence (CE) after its free distribution launched by the Italian Ministry of Health. Opinions elicited using a standardised questionnaire delivered either by mail or during educational or professional meetings. Twenty percent (n = 1350) doctors participated the study. Most of them found CE's content valid, useful and relevant for their clinical practice, and said CE can foster communications among clinicians, particularly among GPs and specialists. Hospital doctors (63%) more often than GPs (48%) read the detailed presentation of individual chapters. Twenty-nine percent said CE brought changes in their clinical practice. Doctors appreciated CE's nature of an evidence-based information compendium and would have not preferred a collection of practice guidelines. Overall, the pilot initiative launched by the Italian Ministry of Health seems to have been well received and to support the subsequent decision to make the Italian edition of Clinical Evidence concise available to all doctors practising in the country. Local implementation initiatives should be warranted to favour doctor's use of CE.

The bacterial community composition and structure of water from an established teleost fish system was examined before, during and after a major water change to explore the impact of such a water-change disturbance on the stability of the aquarium water microbiome. The diversity and evenness of the bacterial community significantly increased following the 90% water replacement. While the change in bacterial community structure was significant, it was slight, and was also weakly correlated with changes in physicochemical parameters. Interestingly there was a significant shift in the correlative network relationships between operational taxonomic units from before to after the water replacement. We suggest this shift in network structure is due to the turnover of many taxa during the course of water replacement. These observations will inform future studies into manipulation of the microbiome by changing system environmental parameter values to optimize resident animal health. PMID:26031788

Referral of periodontal patients requires development of a complex set of decision making skills. This study was conducted to determine criteria used by dental and dental hygiene students regarding the referral of periodontal patients for specialty care. Using mixed methods, a thirteen-item survey was developed to elicit the students' perceptions of their knowledge, confidence regarding managing patients, and clinical reasoning related to periodontal patients. The instrument was administered during the summer prior to (T1) and at the end of the students' final year (T2) of training. Seventy-nine dental students (81 percent of total class) and thirty dental hygiene students (83 percent of total class) completed T1. At T2, forty-two dental (44 percent of total class) and twenty-six dental hygiene students (87 percent of total class) completed the questionnaire. While 90 percent of dental and 96 percent of dental hygiene respondents reported a willingness to refer patients with active disease to specialists, only 40 percent of dental and 36 percent of dental hygiene respondents reported confidence in diagnosing, treating, and appropriately referring such patients. The students' ability to recognize critical disease and risk factors influencing referral was good; however, clinical application of that knowledge indicated a gap between knowledge and applied reasoning. The students' attitudes about the importance of periodontal disease and their perceived competence to identify critical disease risk factors were not significantly related (p>0.05) to correct clinical decisions in the case scenarios. The study concludes that dental and dental hygiene curricula should emphasize both the acquisition and application of knowledge regarding criteria for referral of periodontal patients.

Evaluation is crucial for integration of e-Health/m-Health into healthcare systems and health technology assessment (HTA) could offer sound methodological basis for these evaluations. Aim of this study was to look for HTA reports on e-Health/m-Health technologies and to analyze their transparency, consistency and thoroughness, with the goal to detect areas that need improvement. PubMed, ISI-WOS, and University of York - Centre for Reviews and Dissemination-electronic databases were searched to identify reports on e-Health/m-Health technologies, published up until April 1, 2016. The International Network of Agencies for Health Technology Assessment (INAHTA) checklist was used to evaluate transparency and consistency of included reports. Thoroughness was assessed by checking the presence of domains suggested by the European network for Health Technology Assessment (EUnetHTA) HTA Core Model. Twenty-eight reports published between 1999 and 2015 were included. Most were delivered by non-European countries (71.4 percent) and only 35.7 percent were classified as full reports. All the HTA reports defined the scope of research whereas more than 80 percent provided author details, summary, discussed findings, and conclusion. On the contrary, policy and research questions were clearly defined in around 30 percent and 50 percent of reports. With respect to the EUnetHTA Core Model, around 70 percent of reports dealt with effectiveness and economic evaluation, more than 50 percent described health problem and approximately 40 percent organizational and social aspects. E-Health/m-Health technologies are increasingly present in the field of HTA. Yet, our review identified several missing elements. Most of the reports failed to respond to relevant assessment components, especially ethical, social and organizational implications.

Separation, Aspiration, and Fat Equalization: SAFE Liposuction Concepts for Comprehensive Body Contouring.

PubMed

Wall, Simeon H; Lee, Michael R

2016-12-01

Separation, aspiration, and fatty equilibration (SAFE) liposuction uses a process approach to body contouring and minimizes injury to surrounding structures. The multistep process allows for (1) fat separation, (2) lipoaspiration, and (3) fat equalization. The purpose of this study was to review both outcomes and complications of primary SAFE liposuction. Retrospective chart review was completed of patients undergoing SAFE liposuction from January of 2006 to January of 2011. Patient selection was limited to those undergoing liposuction alone with no adjuvant excisional procedures. Data were collected regarding demographics, body mass index, operative details, and outcomes. Seven hundred thirty-four patients were identified as having undergone SAFE liposuction. One hundred twenty-nine patients were found to have been treated with liposuction alone. Patient age ranged from 18 to 42 years and body mass index ranged from 18 to 42 kg/m (mean, 26.3 kg/m). Seven patients (5.4 percent) underwent treatment of the face and neck, six patients (4.7 percent) underwent treatment of upper extremities, 13 patients (10.1 percent) underwent treatment of the chest, 20 patients (15.5 percent) underwent treatment of lower extremities, 32 patients (24.8 percent) underwent treatment of the circumferential trunk, and 51 patients (39.5 percent) underwent treatment of circumferential trunk and additional area(s). No major complications occurred. Five of the 129 patients (3.87 percent) developed the minor complication of seroma formation. SAFE liposuction is a multistep process approach to body contouring consisting of (1) fat separation, (2) lipoaspiration, and (3) fat equalization. The results of this study show such technique to be safe and effective. Therapeutic, IV.

The Hydrological Simulation Program— FORTRAN model was used to assess the effects of two best-management practices—brush management (removal of woody species locally known as cedar) and weather modification (rainfall enhancement)—on selected hydrologic processes in six subbasins that compose the upper Seco Creek Basin in south-central Texas. A parameter set for use with the model was developed to simulate surface-water-budget components for the six gaged subbasins.Simulation of brush management, represented by decreases in simulated evapotranspiration of 5 to 6 percent, resulted in increases of 1 to 47 percent in annual runoff and increases of 14 to 48 percent in surface runoff for the six subbasins. Simulation of weather modification, represented by a 10-percent increase in rainfall totals and intensities, resulted in increases of 5 to 6 percent in evapotranspiration, increases of 2 to 92 percent in annual runoff, and increases of 36 to 101 percent in surface runoff. Rainfall and runoff data for the study were collected during January 1, 1991–September 30, 1998. Data from 60 storms were used for the simulations. The model was calibrated with data from 33 storms (in two subbasins) and tested with data from 27 storms (in four subbasins). Twenty-one pervious land segments were defined for the study on the basis of geology and land cover. An error analysis and a sensitivity analysis were done on each subbasin, and the results were used to develop the final parameter set.

Third-body wear can adversely affect the outcome of total hip arthroplasty by causing increased polyethylene wear, osteolysis, and component loosening. We hypothesized that there would be greater generation and migration of metal debris to the bearing surfaces in hips in which cobalt-chromium cables were used to reattach the osteotomized greater trochanter when compared with hips in which stainless steel wires were used. Between June 1981 and December 1983, 196 consecutive total hip arthroplasties were performed with use of an Iowa stem and a titanium-backed cemented acetabular component, with cobalt-chromium cable trochanteric reattachment. After nineteen to twenty years of follow-up, the patients were evaluated with regard to the depth of head penetration into the polyethylene (as a surrogate for wear), osteolysis, loosening, and the need for revision. The results were compared with those for a series of 304 total hip arthroplasties that were performed by the same surgeon from January 1984 to December 1985 with use of the same components and the same surgical technique, but with stainless steel wire trochanteric reattachment. The two groups had a comparable nineteen to twenty-year follow-up. All living patients (fifty-nine hips in the cable group and ninety-two hips in the wire group) had minimum ten-year follow-up radiographs. The polyethylene wear rate was 0.101 mm/yr for the cable group and 0.082 mm/yr for the wire group (p = 0.039). For the living patients, the rate of revision of the acetabular component because of aseptic loosening was 37.3% (twenty-two hips) for the cable group and 20.7% (nineteen hips) for the wire group (p = 0.025). The rate of acetabular osteolysis was 44% (twenty-six hips) for the cable group and 26% (twenty-four hips) for the wire group (p = 0.022). Kaplan-Meier analysis with revision of the acetabular component because of aseptic loosening as the end point demonstrated survival rates of 73.7% +/- 9% and 83% +/- 7% for the cable and wire groups, respectively, at twenty years (p = 0.03). Because cable trochanteric attachment led to significantly greater polyethylene wear, osteolysis, acetabular loosening, and acetabular revision, presumably due to third-body metallic debris generation in this cemented total hip replacement construct, surgeons should be aware of the deleterious effects of third-body debris and avoid the use of potential debris generators in the total hip arthroplasty construct. If cable is used and fretting is recognized, especially with intra-articular migration of metallic material or nonunion of the greater trochanter, consideration should be given to cable removal.

The energy required to play active videogames (AVGs) has been reported on in the literature; however, little is known about how children use such games in their home environment. The aim of this study was to investigate children's use of AVGs and the association among AVG use, other screen-based activities, and physical activity levels. Eight hundred and twenty children 12.1 (0.6) years of age participated. Physical activity levels, sedentary screen-based activities, and AVG use were investigated. Differences across genders and deprivation indices were also analyzed. Fifty-eight percent of children met minimal physical activity guidelines. Forty-seven percent of children exceeded screen time recommendations. Of those who had access to AVGs, more children played sedentary games (or active games in a sedentary manner [68 percent]) than active games (55 percent) on AVG consoles. Furthermore, sedentary games were played for longer than active games. AVG play was positively correlated with reported time spent watching television (P=0.02). In free-living conditions AVG consoles are being used by more children and for longer durations as sedentary screen-based devices rather than active screen-based devices.

The present study was connected in order to evaluate the relationship between biological, cognitive and psychosocial characteristics of mothers and the weight of infant at the time of birth. In order to conduct this research a sample of 910 women among recently delivered mothers of Isfahan province in 2009 were selected. From stratified sampling and cluster sampling according to the percentage of population in each of the cities of Isfahan Province was used. The data was gathered with a questionnaire prepared by the researcher in order to evaluate the biological cognitive and psychosocial characteristics of mothers, in addition to the Enrich marital satisfaction test. After collecting data, the analysis of the data was done with SPSS software in two categories of descriptive and inferential statistics by using logistic regression model. The results showed that the prevalence of low weight infants was 9.5 percent and 38.7 percent of pregnancies was unwanted. Twenty-nine percent of mothers had marital dissatisfaction. 15/6 percent of pregnancies were below 20 years old and 22 percent was above of 35 years old. 38.9 percent of mothers were exposed to cigarette smoke. The average of weight gain during pregnancies was 9 kilograms. Thirty three percent of mothers had high blood pressure during pregnancy, 26.7 percent had history of abortion and 31.9 percent had history of bleeding. 23/1percent of women was employed during pregnancy, 19.8 percent gave twin birth and 21/1 percent of parents were relative of each other, 29.7 percent of deliveries were done in cesarean way. The results of this study showed that severe marital dissatisfaction, abnormal blood pressure during pregnancy, being employed during pregnancy, weight gain less than 5 Kg during pregnancy, pregnancy below the age of 20 can meaning fully increase the possibility of low birth weight in infant (α=0.05). The results were consisting with the previous findings and indicated that some of the applicable benefits of this research can be recording of information about each delivery in the whole country with holding training workshops of before and during pregnancy skills by welfare organization.

The effects of supplementing crossbred cows with non-conventional protein sources on dry matter intake, milk yield parameters and economic returns were investigated. Twenty-five lactating F1 Holstein-Mashona crossbreds averaging 115 ± 24 days in milk were used. Five treatments, total mixed ration (TMR), urea-treated maize stover, untreated maize stover, Macroptilium atropurpureum (Siratro) hay and veld hay, were randomly assigned to cows and replicated five times in a completely randomised design. Nutrient composition, intake, milk yield and economic returns were determined. M. atropurpureum hay, urea-treated maize stover and TMR had equal crude protein content. Daily dry matter intake and yield differed significantly among the treatment diets (P < 0.05). Cows on TMR, urea-treated maize stover and M. atropurpureum consumed more (P < 0.05) than cows on untreated maize stover and veld hay. Supplementing with TMR, urea-treated maize stover and M. atropurpureum hay increased (P < 0.05) milk yields. Mean daily milk yield was highest for cows supplemented with urea-treated maize stover. Percent fat, protein and total solids in milk from cows fed urea-treated stover compared favourably to that of milk for cows supplemented with TMR. Income over supplement cost was highest for cows supplemented with M. atropurpureum hay and urea-treated maize stover. Urea-treated maize stover and M. atropurpureum can therefore be used as a replacer protein supplements for dairy cattle in Zimbabwe.

The authors' objective was to evaluate the long-term performance of a resin-based composite restorative material (Beautifil, Shofu, Kyoto, Japan) in combination with a self-etching primer (FL-Bond, Shofu) for posterior restorations. Two clinicians placed 61 restorations, 26 Class I and 35 Class II, in 31 patients. They placed restorations while using rubber dam isolation. Two other clinicians examined the restorations according to the modified U.S. Public Health Service (USPHS) criteria, observing color match, marginal adaptation, anatomy, surface roughness, marginal staining, interfacial staining, proximal and occlusal contacts, secondary caries, postoperative sensitivity and luster. Clinicians examined restorations at baseline as well as at one-, two-, four-, eight- and 13-year recall visits. All restorations were examined at one year, 58 (95 percent) at two years, 39 (64 percent) at four years and 41 (67 percent) at eight years; at the 13-year recall examination, 41 (67 percent) either were examined or had a known outcome. Of the 41 restorations seen at the 13-year examination, 25 restorations (14 Class I and 11 Class II) were intact and acceptable, two had secondary caries and 14 either were not present or had failed (two were missing, 10 had received crowns and two had been replaced). No changes were observed in the modified USPHS criteria for 12 of the 25 restorations that were intact (48 percent). Areas of change observed in 13 of the 25 intact restorations included color match (12 percent), marginal adaptation at the occlusal (20 percent) and proximal surfaces (4 percent), marginal staining on occlusal (24 percent) and proximal surfaces (8 percent), and interfacial staining on occlusal (4 percent) and proximal surfaces (12 percent). The study results showed that most of the restorations observed at the 13-year recall examination maintained acceptable clinical qualities. Beautifil restorative material demonstrated long-term successful results for restoration of posterior teeth.

Resident doctors (residents) play a significant role in the education of medical students. Morning work rounds provide an optimal venue to assess resident teaching. The purpose of this study was to assess the feasibility of peer observation of resident work rounds, to evaluate resident perceptions of peer observation and to evaluate resident perceptions of peer feedback.   Twenty-four internal medicine residents were simultaneously observed by an attending physician and a peer while teaching during work rounds (between August2008 and May 2009). At year-end, residents received a survey to characterise their attitudes towards peer observation and feedback. Twenty-one residents (87.5%) completed the survey. Half (52.4%) felt that participating in the peer observation study stimulated their interest in teaching during work rounds. Prior to participation in the study, fewer than half (42.9%) felt comfortable being observed by their peers, compared with 71.4 percent after participation (p=0.02). The proportion of residents who felt comfortable giving feedback to peers increased from 26.3 to 65.0percent (p=0.004), and the proportion of residents who felt comfortable receiving feedback from peers increased from 76.2 to 95.2 percent (p=0.02). Peer observation and feedback of resident teaching during work rounds is feasible and rewarding for the residents involved. Comfort with regards to being observed by peers, with receiving feedback from peers and with giving feedback to peers significantly increased after the study. Most residents reported changes in their teaching behaviour resulting from feedback. Residents felt that observing a peer teach on work rounds was one of the most useful activities to improve their own teaching on work rounds. © Blackwell Publishing Ltd 2013.

Food allergy is an increasing health problem in the developed world. Cow's milk protein is the main cause of food allergy in infants. Without an appropriate diagnostic workup, there is a high risk of both over- and underdiagnosis and therefore, over and undertreatment. The objective of our study was to analyze the variability in cow's milk protein allergy (CMPA) management by pediatric gastroenterologists in Spain. A fifty item questionnaire, including open and closed items in a Likert's scale from 0 to 5, was drafted and distributed through the Spanish Society for Pediatric Gastroenterology, Hepatology and Nutrition (SEGHNP) e-mail list. Seventy-three questionnaires were received back out of 321. Only 3 of the items achieved concordance greater than 90%. Thirty-three percent considered oral challenge to be necessary for the diagnosis of CMPA under any circumstance. Twenty-five percent considered that symptom improvement after cow's milk removal was enough for the diagnosis. Oral challenge was performed at home by 83.5% in non-IgE mediated cases. Extensively hydrolyzed casein formulas were the treatment of choice for 69.9%. Soy formulas were the last option. Almost all respondents were aware of the existence of clinical guidelines on CMPA, being European Society of Pediatric Gastroenterology, Hepatology and Nutrition guidelines the most followed (64.4%). Twenty-three percent considered that their knowledge about allergy was inadequate. Although CMPA is a prevalent condition that pediatric gastroenterologists have been treating for decades, we found a huge variability on its management. There is potential for improvement in this field among pediatric gastroenterologist in the future. Copyright © 2017. Publicado por Elsevier España, S.L.U.

Results are documented of a study of the cost effectiveness of the stream-gaging program in northeastern California. Data uses and funding sources were identified for the 127 continuous stream gages currently being operated in the study area. One stream gage was found to have insufficient data use to warrant cooperative Federal funding. Flow-routing and multiple-regression models were used to simulate flows at selected gaging stations. The models may be sufficiently accurate to replace two of the stations. The average standard error of estimate of streamflow records is 12.9 percent. This overall level of accuracy could be reduced to 12.0 percent using computer-recommended service routes and visit frequencies. (USGS)

The potential of cyanate resins as replacement for epoxy resins in composites with graphite fiber reinforcement was investigated in an effort to provide improved moisture resistance and toughness in laminating systems at a projected cost, handleability, and processing requirements equivalent to 400 K (260 F) curing epoxies. Monomer synthesis, formulation, blending, resin preparation, catalysis studies, prepreg preparation, laminate fabrication, and testing are discussed. A graphite fiber reinforced laminate was developed with 95 percent retention of the original 363 K (180 F) flexural strength and 70 percent retention of the 363 K (180 F) short beam shear strength after 500 hour exposure to 95 + 7 relative humidity at 324 K (120 F).

J Strength Cond Res 30(8): 2194-2201, 2016-Elevated lean (skeletal muscle) mass is associated with increased muscle strength and anaerobic exercise performance, whereas low levels of lean mass are associated with insulin resistance and sarcopenia. Therefore, studies aimed at obtaining an improved understanding of mechanisms related to the quantity of lean mass are of interest. Percent lean mass (total lean mass/body weight × 100) in 77 young subjects (18-35 years) was measured with dual-energy x-ray absorptiometry. Twenty analytes and 296 metabolites were evaluated with the use of the standard chemistry screen and mass spectrometry-based metabolomic profiling, respectively. Sex-adjusted multivariable linear regression was used to determine serum analytes and metabolites significantly (p ≤ 0.05 and q ≤ 0.30) associated with the percent lean mass. Two enzymes (alkaline phosphatase and serum glutamate oxaloacetate aminotransferase) and 29 metabolites were found to be significantly associated with the percent lean mass, including metabolites related to microbial metabolism, uremia, inflammation, oxidative stress, branched-chain amino acid metabolism, insulin sensitivity, glycerolipid metabolism, and xenobiotics. Use of sex-adjusted stepwise regression to obtain a final covariate predictor model identified the combination of 5 analytes and metabolites as overall predictors of the percent lean mass (model R = 82.5%). Collectively, these data suggest that a complex interplay of various metabolic processes underlies the maintenance of lean mass in young healthy adults.

Composite component designs were developed for a number of applicable engine parts and functions. The cost and weight of each detail component was determined and its effect on the total engine cost to the aircraft manufacturer was ascertained. The economic benefits of engine or nacelle composite or eutectic turbine alloy substitutions was then calculated. Two time periods of engine certification were considered for this investigation, namely 1979 and 1985. Two methods of applying composites to these engines were employed. The first method just considered replacing an existing metal part with a composite part with no other change to the engine. The other method involved major engine redesign so that more efficient composite designs could be employed. Utilization of polymeric composites wherever payoffs were available indicated that a total improvement in Direct Operating Cost (DOC) of 2.82 to 4.64 percent, depending on the engine considered, could be attained. In addition, the percent fuel saving ranged from 1.91 to 3.53 percent. The advantages of using advanced materials in the turbine are more difficult to quantify but could go as high as an improvement in DOC of 2.33 percent and a fuel savings of 2.62 percent. Typically, based on a fleet of one hundred aircraft, a percent savings in DOC represents a savings of four million dollars per year and a percent of fuel savings equals 23,000 cu m (7,000,000 gallons) per year.

Cocaine treatment trials suffer from a high rate of attrition. We examined pretreatment neurophysiological factors to identify participants at greatest risk. Twenty-five participants were divided into concordant and discordant groups following electroencephalogram (EEG) measures recorded prior to a double-blind, placebo-controlled treatment trial. Three possible outcomes were examined: successful completion, dropout, and removal. Concordant (high perfusion correlate) participants had an 85% rate of successful completion, while discordant participants had a 15% rate of successful completion. Twenty-five percent of dropouts and 50% of participants removed were discordant (low perfusion correlate), while only 25% of those who completed were discordant. Failure to complete the trial was not explained by depression, craving, benzoylecgonine levels or quantitative electroencephalogram (QEEG) power; thus cordance may help identify attrition risk.

The possibility of replacing soybean meal and corn-steep liquor by food wastes of the oilpress industry and the meal of the sunflower oil cake in particular is discussed as applied to the fermentation media for production of antifungal antibiotics, such as levorin, mycoheptin, amphotericin. The studies showed that replacement of soybean meal by sunflower oil cake meal with simultaneous increasing of the amount of carbohydrates in the medium increased the levorin levels by 60--70 per cent as compared to the media used at present. When soybean meal and corn-steep liquor were simultaneously replaced by sunflower oil cake meal in amounts of 3--4 per cent the levels of mycoheptin in the fermentation broth increased by 30--65 per cent respectively. Replacement of soybean meal and corn-steep liquor by 3 per cent of sunflow oil cake meal in the medium used presently increased the amphotericin levels by 27 percent as compared to the control. Therefore, sunflower oil cake meal is a substitute of full value for soybean meal and corn-steep liquor in the fermentation media for production of antifungal antibiotics.

Plasma osmotic changes during major abdominal surgery.

PubMed

Malone, R A; McLeavey, C A; Arens, J F

1977-12-01

Fluid balance across the capillary membrane is maintained normally by a balance of hydrostatic and colloid osmotic pressures (COP). In 12 patients having major intra-abdominal procedures, the COP was followed during the operative and immediate postoperative periods. The patients' intraoperative fluid management consisted of replacing shed blood with blood and following Shires' concept of crystalloid replacement. Significant decreases in COP to approximately two thirds of the initial value occurred in patients having intra-abdominal procedures versus only a 10 percent decrease in those having peripheral procedures (greater than .001). As a result of this decrease in COP, the balance between hydrostatic and colloid osmotic pressures is lost and risk of pulmonary intersitial edema is increased.

Hypertension Knowledge, Awareness, and Attitudes in a Hypertensive Population

PubMed Central

Oliveria, Susan A; Chen, Roland S; McCarthy, Bruce D; Davis, Catherine C; Hill, Martha N

2005-01-01

OBJECTIVE Improved recognition of the importance of systolic blood pressure (SBP) has been identified as one of the major public health and medical challenges in the prevention and treatment of hypertension (HTN). SBP is a strong independent risk factor for cardiovascular disease but no information is available on whether patients understand the importance of their SBP level. The purpose of this study was to assess HTN knowledge, awareness, and attitudes, especially related to SBP in a hypertensive population. DESIGN/SETTING/PATIENTS We identified patients with HTN (N =2,264) in the primary care setting of a large midwestern health system using automated claims data (International Classification of Diseases, Ninth Revision [ICD-9] codes 401.0–401.9). We randomly selected 1,250 patients and, after excluding ineligible patients, report the results on 826 completed patient telephone interviews (72% response rate [826/1,151]). MAIN RESULTS Ninety percent of hypertensive patients knew that lowering blood pressure (BP) would improve health and 91% reported that a health care provider had told them that they have HTN or high BP. However, 41% of patients did not know their BP level. Eighty-two percent of all patients correctly identified the meaning of HTN as “high blood pressure.” Thirty-four percent of patients correctly identified SBP as the “top” number of their reading; 32% correctly identified diastolic blood pressure (DBP) as the “bottom” number; and, overall, only 30% of patients were able to correctly identify both systolic and diastolic BP measures. Twenty-seven percent of patients with elevated SBP and DBP (as indicated by their medical records) perceived that their BP was high. Twenty-four percent of patients did not know the optimal level for either SBP or DBP. When asked whether the DBP or SBP level was more important in the control and prevention of disease, 41% reported DBP, 13% reported SBP, 30% reported that both were important, and 17% did not know. CONCLUSIONS These results suggest that, although general knowledge and awareness of HTN is adequate, patients do not have a comprehensive understanding of this condition. For instance, patients do not recognize the importance of elevated SBP levels or the current status of their BP control. An opportunity exists to focus patient education programs and interventions on the cardiovascular risk associated with uncontrolled HTN, particularly elevated SBP levels. PMID:15836524

Potential population-level nutritional impact of replacing whole and reduced-fat milk with low-fat and skim milk among US children aged 2-19 years.

Dietary guidance emphasizes plain low-fat and skim milk over whole, reduced-fat, and flavored milk (milk eligible for replacement [MER]). The objective of this study was to evaluate the population-level impact of such a change on energy, macronutrient and nutrient intakes, and diet cost. Cross-sectional modeling study. Data from the 2001-2002 and 2003-2004 National Health and Nutrition Examination Survey. A total of 8,112 children aged 2-19 years. Energy, macronutrient, and micronutrient intake before and after replacement of MER with low-fat or skim milk. Survey-weighted linear regression models. Milk eligible for replacement accounted for 46% of dairy servings. Among MER consumers, replacement with skim or low-fat milk would lead to a projected reduction in energy of 113 (95% confidence interval [CI], 107-119) and 77 (95% CI, 73-82) kcal/d and percent energy from saturated fat by an absolute value of 2.5% of total energy (95% CI, 2.4-2.6) and 1.4% (95% CI, 1.3-1.5), respectively. Replacement of MER does not change diet costs or calcium and potassium intake. Substitution of MER has the potential to reduce energy and total and saturated fat intake with no impact on diet costs or micronutrient density. The feasibility of such replacement has not been examined and there may be negative consequences if replacement is done with non-nutrient-rich beverages. Copyright © 2015. Published by Elsevier Inc.

Nutrient and pesticide contamination bias estimated from field blanks collected at surface-water sites in U.S. Geological Survey Water-Quality Networks, 2002–12

USGS Publications Warehouse

Medalie, Laura; Martin, Jeffrey D.

2017-08-14

Potential contamination bias was estimated for 8 nutrient analytes and 40 pesticides in stream water collected by the U.S. Geological Survey at 147 stream sites from across the United States, and representing a variety of hydrologic conditions and site types, for water years 2002–12. This study updates previous U.S. Geological Survey evaluations of potential contamination bias for nutrients and pesticides. Contamination is potentially introduced to water samples by exposure to airborne gases and particulates, from inadequate cleaning of sampling or analytic equipment, and from inadvertent sources during sample collection, field processing, shipment, and laboratory analysis. Potential contamination bias, based on frequency and magnitude of detections in field blanks, is used to determine whether or under what conditions environmental data might need to be qualified for the interpretation of results in the context of comparisons with background levels, drinking-water standards, aquatic-life criteria or benchmarks, or human-health benchmarks. Environmental samples for which contamination bias as determined in this report applies are those from historical U.S. Geological Survey water-quality networks or programs that were collected during the same time frame and according to the same protocols and that were analyzed in the same laboratory as field blanks described in this report.Results from field blanks for ammonia, nitrite, nitrite plus nitrate, orthophosphate, and total phosphorus were partitioned by analytical method; results from the most commonly used analytical method for total phosphorus were further partitioned by date. Depending on the analytical method, 3.8, 9.2, or 26.9 percent of environmental samples, the last of these percentages pertaining to all results from 2007 through 2012, were potentially affected by ammonia contamination. Nitrite contamination potentially affected up to 2.6 percent of environmental samples collected between 2002 and 2006 and affected about 3.3 percent of samples collected between 2007 and 2012. The percentages of environmental samples collected between 2002 and 2011 that were potentially affected by nitrite plus nitrate contamination were 7.3 for samples analyzed with the low-level method and 0.4 for samples analyzed with the standard-level method. These percentages increased to 14.8 and 2.2 for samples collected in 2012 and analyzed using replacement low- and standard-level methods, respectively. The maximum potentially affected concentrations for nitrite and for nitrite plus nitrate were much less than their respective maximum contamination levels for drinking-water standards. Although contamination from particulate nitrogen can potentially affect up to 21.2 percent and that from total Kjeldahl nitrogen can affect up to 16.5 percent of environmental samples, there are no critical or background levels for these substances.For total nitrogen, orthophosphate, and total phosphorus, contamination in a small percentage of environmental samples might be consequential for comparisons relative to impairment risks or background levels. At the low ends of the respective ranges of impairment risk for these nutrients, contamination in up to 5 percent of stream samples could account for at least 23 percent of measured concentrations of total nitrogen, for at least 40 or 90 percent of concentrations of orthophosphate, depending on the analytical method, and for 31 to 76 percent of concentrations of total phosphorus, depending on the time period.Twenty-six pesticides had no detections in field blanks. Atrazine with 12 and metolachlor with 11 had the highest number of detections, mostly occurring in spring or early summer. At a 99-percent level of confidence, contamination was estimated to be no greater than the detection limit in at least 98 percent of all samples for 38 of 40 pesticides. For metolachlor and atrazine, potential contamination was no greater than 0.0053 and 0.0093 micrograms per liter in 98 percent of samples. For 11 of 14 pesticides with at least one detection, the maximum potentially affected concentration of the environmental sample was less than their respective human-health or aquatic-life benchmarks. Small percentages of environmental samples had concentrations high enough that atrazine contamination potentially could account for the entire aquatic-life benchmark for acute effects on nonvascular plants, that dieldrin contamination could account for up to 100 percent of the cancer health-based screening level, or that chlorpyrifos contamination could account for 13 or 12 percent of the concentrations in the aquatic-life benchmarks for chronic effects on invertebrates or the criterion continuous concentration for chronic effects on aquatic life.

von Bergmann, Hsingchi; Dalrymple, Kirsten R; Shuler, Charles F

2014-04-01

This study sought to determine whether using the Myers-Briggs Type Indicator (MBTI) would detect differences in personality preferences in first-year dental students admitted to the same dental school through different admission methods. First-year dental students admitted in 2000 and 2001 were given the MBTI instrument during orientation prior to the start of classes. In fall 2000, the Class of 2004 had 140 students, with 116 in the traditional track and twenty-four in the parallel problem-based learning (PBL) track. In fall 2001, the Class of 2005 had 144 students, all enrolled in the PBL curriculum. All students admitted to the PBL track had experienced a process that included evaluation of their participation in a small group. Students in the traditional track had individual interviews with faculty members. Both student groups were required to meet the same baseline grade point average and Dental Admission Test standards. In 2000, the PBL students showed personality preferences that were distinctly different from the personality preferences of traditional track students in the categories of Extroversion (89 percent PBL, 44 percent traditional) and Thinking (72 percent PBL, 39 percent traditional). In 2001, the all-PBL class retained the trend towards Extroversion (69 percent). This study suggests that admission method may effectively change the personality preference distribution exhibited by the students who are admitted to dental school.

Older women and health: an overview.

PubMed

Lewis, M

1985-01-01

Older women's health issues are unique. There are more older women than ever before. They are living increasingly longer than men, yet they report more acute and chronic illness and disability than men. They are disproportionally represented in nursing homes, since many women are alone: twenty-five percent aged 70 or over have no living children and over 60 percent of older women are widowed, divorced, or single. Older women have fewer personal financial resources for health care than men. Health care reimbursement does not meet their needs for financial coverage of chronic outpatient and nursing home care. They face age and sex discrimination on the part of many health care providers and are subject to a growing tendency to be seen as "burdens" and "problems" in the American health care system.

This longitudinal study evaluated subjective, behavioral, and objective auditory function in 83 explosion survivors. Subjects were evaluated quarterly for 1 year with conventional pure-tone and extended high-frequencies audiometry, otoscopic inspections, immittance and speech audiometry, and questionnaires. There was no obvious relationship between subject location and symptoms or test results. Tinnitus, distorted hearing, loudness sensitivity, and otalgia were common symptoms. On average, 76 percent of subjects had predominantly sensorineural hearing loss at one or more frequencies. Twenty-four percent of subjects required amplification. Extended high frequencies showed evidence of acoustic trauma even when conventional frequencies fell within the normal range. Males had significantly poorer responses than females across frequencies. Auditory status of the group was significantly compromised and unchanged at the end of 1-year postblast.

Alloplastic total temporomandibular joint replacements: do they perform like natural joints? Prospective cohort study with a historical control.

PubMed

2016-10-01

The aim of this study was to qualitatively and quantitatively describe the biomechanics of existing total alloplastic reconstructions of temporomandibular joints (TMJ). Fifteen patients with unilateral or bilateral TMJ total joint replacements and 15 healthy controls were evaluated via dynamic stereometry technology. This non-invasive method combines three-dimensional imaging of the subject's anatomy with jaw tracking. It provides an insight into the patient's jaw joint movements in real time and provides a quantitative evaluation. The patients were also evaluated clinically for jaw opening, protrusive and laterotrusive movements, pain, interference with eating, and satisfaction with the joint replacements. The qualitative assessment revealed that condyles of bilateral total joint replacements displayed similar basic motion patterns to those of unilateral prostheses. Quantitatively, mandibular movements of artificial joints during opening, protrusion, and laterotrusion were all significantly shorter than those of controls. A significantly restricted mandibular range of motion in replaced joints was also observed clinically. Fifty-three percent of patients suffered from chronic pain at rest and 67% reported reduced chewing function. Nonetheless, patients declared a high level of satisfaction with the replacement. This study shows that in order to gain a comprehensive understanding of complex therapeutic measures, a multidisciplinary approach is needed.

Stotler, C. L.; Yokel, S. A.

1989-01-01

The objective was to demonstrate the cost and weight advantages that could be obtained by utilizing the graphite/PMR15 material system to replace titanium in selected turbofan engine applications. The first component to be selected as a basis for evaluation was the outer bypass duct of the General Electric F404 engine. The operating environment of this duct was defined and then an extensive mechanical and physical property test program was conducted using material made by processing techniques which were also established by this program. Based on these properties, design concepts to fabricate a composite version of the duct were established and two complete ducts fabricated. One of these ducts was proof pressure tested and then run successfully on a factory test engine for over 1900 hours. The second duct was static tested to 210 percent design limit load without failure. An improved design was then developed which utilized integral composite end flanges. A complete duct was fabricated and successfully proof pressure tested. The net results of this effort showed that a composite version of the outer duct would be 14 percent lighter and 30 percent less expensive that the titanium duct. The other type of structure chosen for investigation was the F404 fan stator assembly, including the fan stator vanes. It was concluded that it was feasible to utilize composite materials for this type structure but that the requirements imposed by replacing an existing metal design resulted in an inefficient composite design. It was concluded that if composites were to be effectively used in this type structure, the design must be tailored for composite application from the outset.

The effect of 0.1 atomic percent zirconium on the cyclic oxidation behavior of beta-NiAl for 300 hours at 1200 C

Barrett, C. A.

1988-01-01

The long time effect of 0.1 at percent Zr (0.2 wt percent Zr) on the cyclic oxidation behavior of hipped beta-NiAl was studied. Oxidation testing was performed in static air at 1200 C for up to 3000 one-hour exposure cycles. Specific weight change versus time data was modeled with the COSP computer program to analyze cyclic oxidation behavior. The Zr-free stoichiometric alloy oxidized and spalled randomly to bare metal between cycles at a rate high enough to deplete Al to a low enough level that oxidation breakaway took place as nonprotective NiO replaced the alpha-Al2O3/NiAl2O4 scale as the controlling oxide. The Zr minimized this severe type of spalling maintaining the protective alpha-Al2O3 scale even out to 3000 hours for the stoichiometric alloy with no significant Al depletion. A third beta-NiAl alloy containing 0.1 at percent Zr but with 10 percent less Al than the stoichiometric alloy was also tested and showed some depletion of Al, but the protective Al2O3/NiAl2O4 was still maintained to close to 2700 hours.

Fourier plane filters

Oliver, D. S.; Aldrich, R. E.; Krol, F. T.

1972-01-01

An electrically addressed liquid crystal Fourier plane filter capable of real time optical image processing is described. The filter consists of two parts: a wedge filter having forty 9 deg segments and a ring filter having twenty concentric rings in a one inch diameter active area. Transmission of the filter in the off (transparent) state exceeds fifty percent. By using polarizing optics, contrast as high as 10,000:1 can be achieved at voltages compatible with FET switching technology. A phenomenological model for the dynamic scattering is presented for this special case. The filter is designed to be operated from a computer and is addressed by a seven bit binary word which includes an on or off command and selects any one of the twenty rings or twenty wedge pairs. The overall system uses addressable latches so that once an element is in a specified state, it will remain there until a change of state command is received. The drive for the liquid crystal filter is ? 30 V peak at 30 Hz to 70 Hz. These parameters give a rise time for the scattering of 20 msec and a decay time of 80 to 100 msec.

Planning for New Primary Airports in the United States: A Survey of Metropolitan Planning Organizations

1999-01-01

Airport congestion at primary airports in major metropolitan areas was analyzed in a report prepared by the Transportation Research Board (TRB) in 1990. Taking the top twenty-three most congested airports from this study, a questionnaire was prepared and sent to the metropolitan planning organizations (MPOs) for twenty of the twenty-three metropolitan areas represented in the TRB study, The questionnaire focused on the role of the MPOs in planning for new primary airports in the United States, including questions about the status of the most recent MPO airport system plan, whether or not the latest plan recommends a new primary airport, and whether or not any other entities in the MPO areas are recommending new primary airports. The results indicated that 44.4 percent of the eighteen respondent MPOs have airport system plans that are five years old or older. Also, only two of the respondent MPOs have recommended a new primary airport in their latest regional airport system plan and only one of these two is a common recommendation in the Federal Aviation Administration's National Plan of Integrated Airport System.

Patients with spina bifida potentially experience social isolation with limited employment opportunities and restriction of independent living, neurologic and intellectual impairment, and orthopaedic and urologic consequences of their condition. However, the degree of disability as these individuals age into adulthood has not been completely delineated. In adults with spina bifida we determined the cause of death for those who had died, IQ, level of education, work history, independent living status, physical disabilities, and urologic status; we then identified surgical procedures that led to better adult function. We retrospectively reviewed 84 individuals with myelomeningocele, examining social, cognitive, and physical disabilities. The minimum age at followup was 20 years (mean, 31 years; range, 20-64 years). Forty-two percent had normal IQs. Seventy percent never needed a neurosurgical shunt and those without shunts had higher IQs. Forty-four percent had regular education and 8% achieved college degrees. Fifty-six percent were unemployed. Thirty percent lived independently. Twenty-three percent were either married or divorced with nine normal offspring. Eighty-five percent dressed themselves, 65% shopped independently, 54% drove. Thirty-one percent were at the thoracic neurologic level (all used wheelchairs), 12% were at L1-L3 (all used a wheelchair except one), 33% were at L4-L5 (78% used a wheelchair at least part-time), and 24% were at S1 and below (all walked). Fifty-four percent experienced decubiti and as a consequence, four required major extremity amputations. Spinal fusions protected sitting balance, but hip surgery did not produce congruent hips and occasionally resulted in debilitating stiffness. Pressure sores resulted in partial foot amputations despite plantigrade feet. Our observations confirm the consequences associated with the physical and cognitive disabilities of patients with spina bifida. Many of these consequences can likely be mitigated by modern multidisciplinary care and special education to increase independence.

Many graduating dentists leave dental school feeling that they are not prepared to start and run a dental practice. The aim of this pilot study was to explore the knowledge and perceptions dental graduates have in the area of practice management. A twenty-item survey was mailed in the fall of 2008 to nearly half of the University of Michigan dental school alumni who had graduated between the years of 1997 and 2007. Respondents were asked about their demographics, practice characteristics, and perceptions of knowledge/experience regarding practice management skills at the present time as well as at graduation. Data were analyzed using descriptive and inferential statistics. The majority of respondents were general practitioners (84 percent) aged thirty to thirty-nine practicing between six and ten years with practice incomes reported to be greater than $300,000 per year (79 percent). Most dentists reported being either an owner or co-owner of the practice (57 percent), and 33 percent reported being an associate in the practice. Upon graduation, 7 percent of the respondents felt that they had a strong knowledge of accounting or human resource issues; this perception increased to 47 percent at the present time. Similarly, less than 6 percent of respondents felt they understood issues pertaining to dental insurance upon graduation; this perception increased to 68 percent after having spent time in the workforce. In contrast to the large increase in knowledge/experience in business aspects of dentistry that had accrued since graduation, most alumni reported only a 7 percent increase in their knowledge of the legal aspects of dental practice. Results from this study indicate that interventions are needed to increase graduating dentists' knowledge of practice management and close the gap between their knowledge and its application in real life. The majority of alumni believed there is a need to improve the curriculum focused on these aspects of dental practice.

Effects of milk replacer composition and intake on the growth of orphan foals were evaluated. Twenty foals were assigned to four treatments: 1) mare-nursed, 2) commercial foal milk replacer at recommended intakes (standard), 3) commercial foal milk replacer at high intakes (high), and 4) acidified replacer at recommended intakes (acidified). Foals fed milk replacer diets were weaned at 12-24 hours postpartum and fed milk replacer for 50 days. Mare-nursed foals were weaned between 52 and 56 days of age. Foals fed replacer diets gained 12% to 28% less weight than mare-nursed foals up to two weeks of age. However, by four months of age, weights of replacer-fed foals were similar to those of mare-nursed foals and 32 other mare-nursed foals at the farm weaned between three and four months postparium. Foals drank 10 to 12 L/100 kg body weight (BW) in fluid replacer daily over the trial period. During the first week, high intake foals consumed 26% more replacer (p<0.05) than foals fed acidified or standard diets. This higher intake resulted in diarrhea earlier (6-11 days vs 11-22 days) and for a longer time (6.3 days vs 2.5-3.6 days) than in foals fed recommended amounts. Mare-nursed foals developed “foal heat scours” in the second week postpartum. After the first week, foals fed high replacer diet voluntarily consumed the same volume of fluid replacer as foals fed the standard intake. Foals ate less than 1 kg grain mix/100 kg BW daily to one month of age, then increased intake to 1.5-2 kg/ 100 kg BW to weaning. Water intake was 20-40% of daily fluid intake and was correlated (r = 0.85) to dry matter intake. Foals in the high intake group ate less (p<0.05) solid feed and drank less water than foals fed the standard and acidified diets. The foal's stomach capacity appears to limit meal size and thus replacer intake. If recommended feeding intervals are used, replacer intakes by foals are less than 15% BW daily. High volume intakes appeared to prolong diarrhea. Normal growth rates occur when replacer and good-quality feeds are fed concurrently. PMID:17424268

The aim of this study was to support health technology assessment (HTA) capacity building in Member States of the European Union with limited experience or without institutionalized HTA. The main output is a Handbook on HTA Capacity Building. The methods used were worldwide surveys of (i) HTA organizations, (ii) information management units, and (iii) HTA educational programs. The results of two surveys (i & ii) were combined with expert opinion to produce the Handbook on HTA Capacity Building. Survey of HTA organizations (n = 41, response rate 35 percent). Most of the organizations were established by the government (61 percent), and all were not-for-profit. Working on HTA (80.5 percent) and doing research (63.4 percent) were the main lines of activity. Survey on information management units (n = 23, response rate 23 percent). Most (74.2 percent) of the responding HTA agencies reported having personnel dedicated to HTA information services. Survey on HTA educational programs (n = 48, response rate 60 percent). In total, nine Master of Science (MSc) programs were identified (three MSc in HTA and six MSc in HTA-related areas). Handbook on HTA Capacity Building. A group of twenty experts from thirteen countries developed the handbook. It consists of nine chapters focusing on HTA institutional development (structural setup, work processes, and visibility). Setting up organizational structures and establishing effective HTA programs that guide key policy decisions is a challenging task. There are no standard models or pathways. "One size fits all" is not a useful principle because of the wide systemic and cultural differences between countries. The Handbook on HTA Capacity Building includes approaches for overall institutional development, especially in formulating objectives, setting up structures, and defining work processes.

Objective To compare the effectiveness of standard and patient-centered, culturally tailored collaborative care (CC) interventions for African American patients with major depressive disorder (MDD) over 12 months of follow-up. Data Sources/Study Setting Twenty-seven primary care clinicians and 132 African American patients with MDD in urban community-based practices in Maryland and Delaware. Study Design Cluster randomized trial with patient-level, intent-to-treat analyses. Data Collection/Extraction Methods Patients completed screener and baseline, 6-, 12-, and 18-month interviews to assess depression severity, mental health functioning, health service utilization, and patient ratings of care. Principal Findings Patients in both interventions showed statistically significant improvements over 12 months. Compared with standard, patient-centered CC patients had similar reductions in depression symptom levels (−2.41 points; 95 percent confidence interval (CI), −7.7, 2.9), improvement in mental health functioning scores (+3.0 points; 95 percent CI, −2.2, 8.3), and odds of rating their clinician as participatory (OR, 1.48, 95 percent CI, 0.53, 4.17). Treatment rates increased among standard (OR = 1.8, 95 percent CI 1.0, 3.2), but not patient-centered (OR = 1.0, 95 percent CI 0.6, 1.8) CC patients. However, patient-centered CC patients rated their care manager as more helpful at identifying their concerns (OR, 3.00; 95 percent CI, 1.23, 7.30) and helping them adhere to treatment (OR, 2.60; 95 percent CI, 1.11, 6.08). Conclusions Patient-centered and standard CC approaches to depression care showed similar improvements in clinical outcomes for African Americans with depression; standard CC resulted in higher rates of treatment, and patient-centered CC resulted in better ratings of care.

2010-12-01

The purpose of this study was to explore the University of Malaya (UM) dental graduates' competence in holistic care in real settings from the employers' and graduates' perspectives. A self-administered questionnaire consisting of ten domains was sent to thirty senior dental officers of the Ministry of Health (MOH) and 164 UM graduates. In this article, nineteen major competencies that best represent the graduates' competence in the provision of holistic care are discussed. Each competency was rated on a scale of 1 (very poor) to 4 (very good) and was categorized as "poor and of major concern" (if less than 60 percent of respondents scored good or very good), "satisfactory and of minor concern" (60-69 percent), or "excellent" (70 percent and above). One hundred and six out of 164 graduates (64.6 percent) and twenty-nine out of thirty employers (96.7 percent) responded. Overall, the employers rated the graduates lower than what the graduates rated themselves on all items. While the graduates felt they were excellent and satisfactory in sixteen out of nineteen items (84.2 percent), the employers felt they were poor in fourteen out of nineteen (73.7 percent). Both groups agreed that the graduates were excellent in communication, but poor in life-saving skills, obtaining patient's family and psychosocial histories, and recognizing signs and symptoms (not intraoral) indicating the presence of a systemic disease. In conclusion, although the graduates felt competent in the majority of the holistic care competencies, the employers had some reservations over such claims. Outcomes of the study led to recommendations to incorporate longer community-based learning hours, an improved behavioral science component, a module for special care patients, and multidepartmental collaborative teachings in the new integrated program aimed for implementation in 2011.

Free flap monitoring in autologous reconstruction after nipple-sparing mastectomy remains controversial. The authors therefore examined outcomes in nipple-sparing mastectomy with buried free flap reconstruction versus free flap reconstruction incorporating a monitoring skin paddle. Autologous free flap reconstructions with nipple-sparing mastectomy performed from 2006 to 2015 were identified. Demographics and operative results were analyzed and compared between buried flaps and those with a skin paddle for monitoring. Two hundred twenty-one free flaps for nipple-sparing mastectomy reconstruction were identified: 50 buried flaps and 171 flaps incorporating a skin paddle. The most common flaps used were deep inferior epigastric perforator (64 percent), profunda artery perforator (12.1 percent), and muscle-sparing transverse rectus abdominis myocutaneous flaps (10.4 percent). Patients undergoing autologous reconstructions with a skin paddle had a significantly greater body mass index (p = 0.006). Mastectomy weight (p = 0.017) and flap weight (p < 0.0001) were significantly greater in flaps incorporating a skin paddle. Comparing outcomes, there were no significant differences in flap failure (2.0 percent versus 2.3 percent; p = 1.000) or percentage of flaps requiring return to the operating room (6.0 percent versus 4.7 percent; p = 0.715) between groups. Buried flaps had an absolute greater mean number of revision procedures per nipple-sparing mastectomy (0.82) compared with the skin paddle group (0.44); however, rates of revision procedures per nipple-sparing mastectomy were statistically equivalent between the groups (p = 0.296). Although buried free flap reconstruction in nipple-sparing mastectomy has been shown to be safe and effective, the authors' technique has evolved to favor incorporating a skin paddle, which allows for clinical monitoring and can be removed at the time of secondary revision.

When the sad history of nuclear power is written, April 26, 1986, will be recorded as the day the dream died. The explosion at the Chernobyl plant was a terrible human tragedy- and it delivered a stark verdict on the hope that nuclear power will one day replace fossil fuel-based energy systems. Nuclear advocates may soldier on, but a decade after Chernobyl it is clear that nuclear power is no longer a viable energy option for the twenty-first century.

There are limited data on the outcomes of elderly patients with chronic kidney disease undergoing renal replacement therapy or conservative management. We aimed to compare survival, hospital admissions and palliative care access of patients aged over 70 years with chronic kidney disease stage 5 according to whether they chose renal replacement therapy or conservative management. Retrospective observational study. Patients aged over 70 years attending pre-dialysis clinic. In total, 172 patients chose conservative management and 269 chose renal replacement therapy. The renal replacement therapy group survived for longer when survival was taken from the time estimated glomerular filtration rate <20 mL/min (p < 0.0001), <15 mL/min (p < 0.0001) and <12 mL/min (p = 0.002). When factors influencing survival were stratified for both groups independently, renal replacement therapy failed to show a survival advantage over conservative management, in patients older than 80 years or with a World Health Organization performance score of 3 or more. There was also a significant reduction in the effect of renal replacement therapy on survival in patients with high Charlson's Comorbidity Index scores. The relative risk of an acute hospital admission (renal replacement therapy vs conservative management) was 1.6 (p < 0.05; 95% confidence interval = 1.14-2.13). A total of 47% of conservative management patients died in hospital, compared to 69% undergoing renal replacement therapy (Renal Registry data). Seventy-six percent of the conservative management group accessed community palliative care services compared to 0% of renal replacement therapy patients. For patients aged over 80 years, with a poor performance status or high co-morbidity scores, the survival advantage of renal replacement therapy over conservative management was lost at all levels of disease severity. Those accessing a conservative management pathway had greater access to palliative care services and were less likely to be admitted to or die in hospital.

How common are cognitive errors in cases presented at emergency medicine resident morbidity and mortality conferences?

Cognitive errors are a major contributor to medical error. Traditionally, medical errors at teaching hospitals are analyzed in morbidity and mortality (M&M) conferences. We aimed to describe the frequency of cognitive errors in relation to the occurrence of diagnostic and other error types, in cases presented at an emergency medicine (EM) resident M&M conference. We conducted a retrospective study of all cases presented at a suburban US EM residency monthly M&M conference from September 2011 to August 2016. Each case was reviewed using the electronic medical record (EMR) and notes from the M&M case by two EM physicians. Each case was categorized by type of primary medical error that occurred as described by Okafor et al. When a diagnostic error occurred, the case was reviewed for contributing cognitive and non-cognitive factors. Finally, when a cognitive error occurred, the case was classified into faulty knowledge, faulty data gathering or faulty synthesis, as described by Graber et al. Disagreements in error type were mediated by a third EM physician. A total of 87 M&M cases were reviewed; the two reviewers agreed on 73 cases, and 14 cases required mediation by a third reviewer. Forty-eight cases involved diagnostic errors, 47 of which were cognitive errors. Of these 47 cases, 38 involved faulty synthesis, 22 involved faulty data gathering and only 11 involved faulty knowledge. Twenty cases contained more than one type of cognitive error. Twenty-nine cases involved both a resident and an attending physician, while 17 cases involved only an attending physician. Twenty-one percent of the resident cases involved all three cognitive errors, while none of the attending cases involved all three. Forty-one percent of the resident cases and only 6% of the attending cases involved faulty knowledge. One hundred percent of the resident cases and 94% of the attending cases involved faulty synthesis. Our review of 87 EM M&M cases revealed that cognitive errors are commonly involved in cases presented, and that these errors are less likely due to deficient knowledge and more likely due to faulty synthesis. M&M conferences may therefore provide an excellent forum to discuss cognitive errors and how to reduce their occurrence.

A 78-year-old man with remote type-A dissection presented with acute-onset dyspnea. Twenty-two years prior, treatment for his aortic disease required replacement of ascending and arch aneurysms with a polyester graft (Dacron) using the graft inclusion technique. He presented currently in cardiogenic shock. Echocardiography demonstrated new severe hypokinesis of all apical segments. Left-heart catheterization revealed a 120 mm Hg intragraft gradient. Computed tomography arteriography was unrevealing, but intraaortic ultrasound demonstrated critical intragraft stenosis. A balloon expandable stent (Palmaz stent, Cordis, Milpitas, CA) was deployed in the stenotic region with gradient resolution. The patient later underwent aortic root replacement and ascending aneurysm repair (Bio-Bentall technique) and is doing well at 24 months. Copyright © 2018 The Society of Thoracic Surgeons.

Treatment of migraine attacks with sumatriptan. The Subcutaneous Sumatriptan International Study Group.

PubMed

1991-08-01

The headache in migraine attacks may be caused by dilatation of certain cranial arteries or arteriovenous anastomoses, by neurogenic dural plasma extravasation, or by both of these mechanisms. Sumatriptan, a novel selective agonist of 5-hydroxytryptamine-like receptors, blocks these phenomena. We investigated its efficacy in migraine. We studied 639 patients with migraine attacks in a randomized, double-blind, placebo-controlled, parallel-group clinical trial. We assessed the effect of subcutaneous injections of 6 or 8 mg of sumatriptan or placebo on the severity of headache and associated migrane symptoms 30, 60, and 120 minutes after treatment. Patients who were not free of pain after 60 minutes subsequently received placebo if they had initially received placebo or 8 mg of sumatriptan, and 6 mg of sumatriptan or placebo if they had initially received 6 mg of sumatriptan. After 60 minutes, the severity of headache was decreased in 72 percent (95 percent confidence interval, 68 to 76 percent) of the 422 patients given 6 mg of sumatriptan, 79 percent (95 percent confidence interval, 71 to 87 percent) of the 109 patients given 8 mg of sumatriptan, and 25 percent (95 percent confidence interval, 17 to 33 percent) of the 105 patients given placebo (data on 3 patients could not be evaluated). As compared with the placebo group, 47 percent (95 percent confidence interval, 38 to 57 percent) more patients who had received 6 mg of sumatriptan and 54 percent (95 percent confidence interval, 43 to 65 percent) more patients who had received 8 mg of sumatriptan had a decrease in the severity of headache (P less than 0.001 for both comparisons). After 120 minutes, 86 to 92 percent of the 511 patients treated with sumatriptan (202 assigned to 6 mg plus placebo, 203 to 6 mg plus 6 mg, and 106 to 8 mg plus placebo) had improvement in the severity of headache, as compared with only 37 percent of the 104 patients who received placebo once or twice (P less than 0.001 for all comparisons). Twenty-one patients were excluded from the analysis because of missing data (19) or protocol violations (2). The response rates did not differ significantly among the sumatriptan regimens. Adverse events were minor and transient in all groups. We conclude that a single 6-mg dose of sumatriptan given subcutaneously is a highly effective, rapid-acting, and well-tolerated treatment for migrane attacks. The administration of a second dose 60 minutes later to patients not responding well to an initial dose affords little additional benefit.

The objective was to investigate the use of autologous red blood cells (RBCs) derived from umbilical cord blood (UCB), as an alternative for allogeneic transfusions in premature infants admitted to a tertiary neonatal center. UCB collection was performed at deliveries of less than 32 weeks of gestation and processed into autologous RBC products. Premature infants requiring a RBC transfusion were randomly assigned to an autologous or allogeneic product. The primary endpoint was an at least 50 percent reduction in allogeneic transfusion needs. Fifty-seven percent of the collections harvested enough volume (> or =15 mL) for processing. After being processed, autologous products (> or =10 mL/kg) were available for 36 percent of the total study population and for 27 percent of the transfused infants and could cover 58 percent (range, 25%-100%) of the transfusion needs within the 21-day product shelf life. Availability of autologous products depended most on the gestational age. Infants born between 24 and 28 weeks had the lowest availability (17%). All products, however, would be useful in view of their high (87%) transfusion needs. Availability was highest (48%) for the infants born between 28 and 30 weeks. For 42 percent of the infants with transfusion needs in this group, autologous products were available. For the infants born between 30 and 32 weeks, autologous products were available for 36 percent of the infants. Transfusion needs in this group were, however, much lower (19%) compared to the other gestational groups. Autologous RBCs derived from UCB could not replace 50 percent of allogeneic transfusions due to the low UCB volumes collected and subsequent low product availability.

A Mexican Committee of Nutrition Experts (MCNE) from the National Institute of Public Health (INSP), free from conflict of interest, established food content standards to place the front-of-package (FOP) logo on foods that meet these nutrition criteria. The objectives were to simulate the effect on nutrient intake in the Mexican adult population (20-59 years old) after replacing commonly consumed processed foods with those that meet the FOP nutrition-labeling criteria. Twenty-four hour dietary recalls were collected from the 2012 Mexican National Health and Nutrition Survey ( n = 2164 adults). A food database from the INSP was used. Weighted medians and 25-75 inter-quartile ranges (IQR) of energy and nutrient intake were calculated for all subjects by sociodemographic characteristics before and after replacing foods. Significant decreases were observed in energy (-5.4%), saturated fatty acids (-18.9%), trans-fatty acids (-20%), total sugar (-36.8%) and sodium (-10.7%) intake and a significant increase in fiber intake (+15.5%) after replacing foods, using the MCNE nutrition criteria. Replacing commonly consumed processed foods in the diet with foods that meet the FOP nutrition-labeling criteria set by the MCNE can lead to improvements in energy and nutrient intake in the Mexican adult population.

To establish whether increased end-of-day discomfort during soft contact lens wear is associated with short-term changes occurring to the lens itself. Twenty-seven subjects wore hydrogel lenses (Focus Dailies; Alcon) bilaterally for 10 hours on two separate days. Comfort was reported using 1-100 numerical rating scales (1 = intolerable discomfort, 100 = lens cannot be felt). Day 1 ratings were taken before lens insertion and at 0.05, 5, and 10 hours post-insertion. Day 2 ratings occurred at similar times, but lenses were removed after the 5-hour assessment and either reinserted (n = 14) or newly replaced (n = 12). An additional rating was taken 5 minutes after re-insertion. Wear then continued to the 10-hour point. In a separate study, 24 different subjects repeated these procedures using a silicone hydrogel lens (AirOptix Aqua; Alcon) with wear taking place on 3 days to permit lens replacement to be with existing as well as new lenses in all subjects. For hydrogel lenses, comfort scores (mean ± 95% CI) reported after 10 hours were 79.4 ± 8.3 when lenses were worn un-replaced, compared with 73.2 ± 9.2 for replacement with the existing lens. When replacement was with a brand new lens, the corresponding values were 72.9 ± 10.9 (un-replaced) versus 69.2 ± 12.8 (new lens replacement). For silicone hydrogel lenses, 10-hour comfort was 90.3 ± 3.2 (un-replaced) versus 92.2 ± 2.9 (replacement with existing lens) versus 90.0 ± 3.3 (replacement with new lens). Differences between replacement conditions were not significant in any case (analysis of variance, p > 0.05). Final comfort was not influenced by replacing lenses midway through the wearing period. Comfort decrements experienced by users of these daily contact lenses towards the later part of the wearing period are not caused by changes occurring to the lenses on this time scale. Possible alternative etiological factors include a fatigue-like response in one or more ocular tissues or stimulation of ocular surface nociceptors induced by the presence of the contact lens.

Large scale manufacture of phosphide based semiconductor devices by organo-metallic vapor phase epitaxy (OMVPE) typically requires the use of highly toxic phosphine. Advancements in phosphine substitutes have identified tertiarybutylphosphine (TBP) as an excellent precursor for OMVPE of InP. High quality undoped and doped InP films were grown using TBP and trimethylindium. Impurity doped InP films were achieved utilizing diethylzinc and silane for p and n type respectively. 16 percent efficient solar cells under air mass zero, one sun intensity were demonstrated with Voc of 871 mV and fill factor of 82.6 percent. It was shown that TBP could replace phosphine, without adversely affecting device quality, in OMVPE deposition of InP thus significantly reducing toxic gas exposure risk.

Intraoperative Comparison of Anatomical versus Round Implants in Breast Augmentation: A Randomized Controlled Trial.

Hidalgo, David A; Weinstein, Andrew L

2017-03-01

The purpose of this randomized controlled trial was to determine whether anatomical implants are aesthetically superior to round implants in breast augmentation. Seventy-five patients undergoing primary breast augmentation had a round silicone implant of optimal volume, projection, and diameter placed in one breast and an anatomical silicone device of similar volume and optimal shape placed in the other. After intraoperative photographs were taken, the anatomical device was replaced by a round implant to complete the procedure. A survey designed to measure breast aesthetics was administered to 10 plastic surgeon and 10 lay reviewers for blind evaluation of the 75 cases. No observable difference in breast aesthetics between anatomical and round implants was reported by plastic surgeons in 43.6 percent or by lay individuals in 29.2 percent of cases. When a difference was perceived, neither plastic surgeons nor lay individuals preferred the anatomical side more often than the round side. Plastic surgeons judged the anatomical side superior in 51.1 percent of cases and the round side superior in 48.9 percent of cases (p = 0.496). Lay individuals judged the anatomical side superior in 46.7 percent of cases and the round side superior in 53.3 percent (p = 0.140). Plastic surgeons identified implant shape correctly in only 26.5 percent of cases. This study provides high-level evidence supporting no aesthetic superiority of anatomical over round implants. Given that anatomical implants have important and unique disadvantages, a lack of proven aesthetic superiority argues against their continued use in breast augmentation. Therapeutic, I.

The developer is able to acquire valuable field operating experience that is not available in a laboratory while the user has the opportunity to become familiar with the new technology and gains a working knowledge of it through hands-on experience. Westinghouse, recognizing these benefits, initiated a program in 1986 by supplying a 400 W SOFC generator to Tennessee Valley Authority. This generator operated for approximately 1,760 hours and was constructed of twenty-four 30 cm thick-wall PST cells. In 1987, three, 3 kW SOFC generators were installed and operated at the facilities of the Tokyo Gas Company and the Osaka Gas Company. At Osaka Gas, two generators were used. First a training generator, operated for 2900 hours before it was replaced on a preplanned schedule with the second generator. The second generator operated for 3,600 hours. Tokyo Gas generator was operated for 4,900 hours. These generators had a 98 percent availability and measured NO(x) levels of less than 1.3 ppm. The 3 kW SOFC generators were constructed of 144 36 cm thick-wall PST cells. The 3 kW generators, as was the TVA generator, were fueled with hydrogen and carbon monoxide. The next major milestone in the field unit program was reached in early 1992 with the delivery to the UTILITIES, a consortium of the Kansai Electric Power company, the Tokyo Gas Company, and the Osaka Gas Company, of a natural gas fueled all electric SOFC system. This system is rated at a nominal 25 kW dc with a peak capacity of 40 kW dc. The NO(x) was measured at less than 0.3 ppM (corrected to 15 percent oxygen). The system consists of 1152 cells (thin-wall PST) of 50 cm active length, manufactured at the PPMF. Cells are contained in two independently controlled and operated generators.

To explore gastroenterologist perceptions towards and experience with faecal microbiota transplantation (FMT). A questionnaire survey consisting of 17 questions was created to assess gastroenterologists' attitude towards and experience with FMT. This was anonymously distributed in hard copy format amongst attendees at gastroenterology meetings in Australia between October 2013 and April 2014. Basic descriptive statistical analyses were performed. Fifty-two clinicians participated. Twenty one percent had previously referred patients for FMT, 8% more than once. Ninety percent would refer patients with Clostridium difficile infection (CDI) for FMT if easily available, 37% for ulcerative colitis, 13% for Crohn's disease and 6% for irritable bowel syndrome. Six percent would not refer any indication, including recurrent CDI. Eighty-six percent would enroll patients in FMT clinical trials. Thirty-seven percent considered the optimal mode of FMT administration transcolonoscopic, 17% nasoduodenal, 13% enema and 8% oral capsule. The greatest concerns regarding FMT were: 42% lack of evidence, 12% infection risk, 10% non infectious adverse effects/lack of safety data, 10% aesthetic, 10% lack of efficacy, 4% disease exacerbation, and 2% inappropriate use; 6% had no concerns. Seventy seven percent believed there is a lack of accessibility while 52% had an interest in learning how to provide FMT. Only 6% offered FMT at their institution. Despite general enthusiasm, most gastroenterologists have limited experience with, or access to, FMT. The greatest concerns were lack of supportive evidence and safety issues. However a significant proportion would refer indications other than CDI for FMT despite insufficient evidence. These data provide guidance on where education and training are required.

Many plastic surgeons advocate smoking cessation before patients undergo cosmetic surgery with extensive soft-tissue dissection. Smoking cessation rates after cosmetic surgery are unknown. The preoperative consultation may be an opportunity to promote long-term smoking cessation. This is a retrospective, cross-sectional cohort study. All patients over an 8-year study period who smoked before their preoperative consultation; who quit 2 weeks before surgery; and who subsequently underwent rhytidectomy, abdominoplasty, or mastopexy were included. Patients were asked to complete a Web-based survey at long-term follow-up. Eighty-five smokers were included, and 47 patients completed the survey, for a response rate of 55.3 percent. Average follow-up was 63.3 months. Five respondents were social smokers and thus excluded. Of the 42 daily smokers, 17 patients (40.5 percent) were no longer smoking cigarettes on a daily basis at long-term follow-up. Of these 17 patients, 10 (23.8 percent) had not smoked since their operation. A total of 24 patients (57.1 percent) had reduced their cigarette consumption by any amount, and 70.8 percent (17 of 24) of these patients agreed that discussing adverse surgical outcomes related to smoking influenced their ability to quit/reduce. Twenty-one of 42 patients (50.0 percent) admitted that they were not compliant with the preoperative smoking cessation instructions. This is the first report to investigate long-term smoking cessation from a cosmetic surgery practice. The authors have shown a positive association between smoking cessation and cosmetic surgery. Requesting a period of cessation before cosmetic surgery may promote long-lasting smoking cessation.

Surgeon Reimbursements in Maxillofacial Trauma Surgery: Effect of the Affordable Care Act in Ohio.

PubMed

2016-02-01

Surgical treatment of maxillofacial injuries has historically been associated with low reimbursements, mainly because of the high proportion of uninsured patients. The Affordable Care Act, implemented in January of 2014, aimed to reduce the number of uninsured. If the Affordable Care Act achieves this goal, surgeons may benefit from improved reimbursement rates. The authors' purpose was to evaluate the effects of the Affordable Care Act on payor distribution and surgeon reimbursements for maxillofacial trauma surgery at their institution. A review of all patients undergoing surgery for maxillofacial trauma between January of 2012 and December of 2014 was conducted. Insurance status, and amounts billed and collected by the surgeon, were recorded. Patients treated before implementation of the Affordable Care Act were compared to those treated after. Five hundred twenty-three patients were analyzed. Three hundred thirty-four underwent surgery before implementation of the Affordable Care Act, and 189 patients underwent surgery after. After implementation of the Affordable Care Act, the proportion of uninsured decreased (27.2 percent to 11.1 percent; p < 0.001) and the proportion of patients on Medicaid increased (7.8 percent to 25.4 percent; p < 0.001). Overall surgeon reimbursement rate increased from 14.3 percent to 19.8 percent (p < 0.001). After implementation of the Affordable Care Act, we observed a significant reduction in the proportion of maxillofacial trauma patients who were uninsured. Surgeons' overall reimbursement rate increased. These trends should be followed over a longer term to determine the full effect of the Affordable Care Act.

Reconnaissance study of the Taylor Mountains pluton, southwestern Alaska

The Taylor Mountains pluton is a Late Cretaceous to early Tertiary (median age 65 + or ? 2 Ma) epizonal, composite biotite granite stock located about 235 km (145 mi) northeast of Dillingham in southwestern Alaska. This 30 km2 (12 mi2) pluton has sharp and discordant contacts with hornfels that developed in Upper Cretaceous clastic sedimentary rocks of the Kuskokwim Group. The three intrusive phases in the Taylor Mountains pluton, in order of emplacement, are (1) porphyritic granite containing large K-feldspar phenocrysts in a coarse-grained groundmass, (2) porphyritic granite containing large K-feldspar and smaller, but still coarse, plagioclase, quartz, and biotite phenocrysts in a fine-grained groundmass, and (3) fine-grained, leucocratic, equigranular granite. The porphyritic granites have different emplacement histories, but similar compositions; averages are 69.43 percent SiO2, 1.62 percent CaO, 5.23 percent FeO+MgO, 3.11 percent Na2O, and 4.50 percent K2O. The fine-grained, equigranular granite is distinctly felsic compared to porphyritic granite; it averages 75.3 percent SiO2, 0.49 percent CaO, 1.52 percent FeO+MgO, 3.31 percent Na2O, and 4.87 percent K2O. Many trace elements including Ni, Cr, Sc, V, Ba, Sr, Zr, Y, Nb, La, Ce, Th, and Nd are strongly depleted in fine-grained equigranular granite. Trace elements are not highly enriched in any of the granites. Known hydrothermal alteration is limited to one tourmaline-quartz replacement zone in porphyritic granite. Mineral deposits in the Taylor Mountains area are primarily placer gold (plus wolframite, cassiterite, and cinnabar); sources for these likely include scattered veins in hornfels peripheral to the Taylor Mountain pluton. The granite magmas that formed the Taylor Mountains pluton are thought to represent melted continental crust that possibly formed in response to high heat flow in the waning stage of Late Cretaceous subduction beneath interior Alaska.

Attitudes toward AIDS were measured by a survey of 212 attendees at the annual meeting of the New Jersey Society for Medical Technology. Twenty five percent of the respondents were considering leaving the profession because of a fear of AIDS. In addition, almost half would not have chosen the field knowing they would be handling HIV-positive samples. This high degree of concern may be an important factor contributing to the shortage of medical technologists. PMID:2400043

The application of autologous lipotransfer (fat grafting, lipofilling) in reconstructive surgery is steadily becoming more popular as evidence of the regenerative and reparative effects of fat becomes better known. The authors investigated the use of autologous lipotransfer for treatment of chronic diabetic and other foot and lower limb ulcers. Twenty-six patients with nonhealing wounds were treated with surgical débridement and autologous lipotransfer (using the débridement and autologous lipotransfer method). The mean age of the wounds before intervention was 16.7 months. Wound size after débridement averaged 5.1 ± 2.6 cm2. On average, 7.1 ± 3.3 cc of lipoaspirate was transferred into the wound area. Twenty-two of 25 wounds (88 percent) healed completely within a mean of 68.0 ± 33.0 days. A reduction of wound size by 50 percent was achieved after an average of 4 weeks. In one patient with an ulcer within particularly scarred tissues on the lower limb, a repeated session of lipotransfer led to complete wound healing after another 4 weeks. The authors describe a simple and useful technique to improve wound healing in diabetic feet and chronic lower limb ulcers with a background of peripheral vascular disease, where other interventional options to achieve wound healing have failed.

To determine the prevalence of HPV-induced lesions in the anal canal of women with cervical intraepithelial neoplasia (CIN) grade 2/3. A cross-sectional study was carried out from December 2008 to June 2009, in Pernambuco, northeastern Brazil. Only women with grade 2/3 CIN were included, and those who could not undergo anoscopy during their first visit were excluded. A cyttobrush was used for sample collection in order to identify HPV DNA through PCR and anal cytology. An anal biopsy was obtained in cases of abnormal anal cytology or major alterations in high resolution anoscopy (HRA). Thirty-two percent (n=37/115) of HRA were normal and 63.5% (n=73/115) showed acetowhite epithelium. Twenty-two percent (n=26/115) of anal cytologies were abnormal. Among the latter, 12.2% (n=14/26) were low-grade anal intraepithelial lesions and 3.4% (n=4/26) were high-grade anal intraepithelial lesions. Twenty-two anal biopsies were performed, 13.7% of which (n=3/22) were grade 2 anal intraepithelial neoplasia (AIN2) and 9% (n=2/22) were grade 3 AIN. Th HPV DNA was identified in 72.1% of cases (n=83/115). Women with CIN grade 2/3 showed a high prevalence of anal HPV infection and HPV-induced lesions.

Objectives To investigate if general dental practitioners (GDPs) in private practice in Jordan follow universal guidelines for preparation of anterior teeth for resin bonded all-ceramic crowns (RBCs). Material and Methods A sample (n=100) of laboratory models containing 208 tooth preparations for IPS Empress and In Ceram, featuring work from different GDPs, was obtained from 8 commercial dental laboratories. Aspects of preparations were quantified and compared with accepted criteria defined following a review of the literature and recommendations of the manufactures' guidelines. Results Subgingival margins on the buccal aspect were noticed in 36% of the preparations, 54% demonstrated overpreparation with a tendency to overprepare the teeth on the mesiodistal plane more than buccolingual plane. Twenty percent of samples presented a shoulder finish line while a chamfer margin design was noticed in 39%. Twenty-nine percent and 12% of samples had either a feathered or no clear margin design respectively. Incisal under preparation was observed in 18% of dies of each type. Only 17% of all preparations were found to follow the recommended anatomical labial preparations while 29% of the RBC preparations were found to have the recommended axial convergence angle. In total, 43% of preparations were found to have the recommended depth of the finish line. Conclusions It was found that relevant guidelines for RBC preparations were not being fully adhered to in private practice in Jordan. PMID:21710098

Few studies have described the challenges experienced by long-term care facilities (LTCFs) following Hurricane Sandy. This study examined LTCF preparedness and experiences during and after the storm. A cross-sectional survey was conducted 2 years after Hurricane Sandy to assess LTCF demographics, preparation, and post-storm resources. Surveys were conducted at LTCFs located on the Rockaway Peninsula of New York City. All LTCFs located in a heavily affected area were approached. Of 29 facilities, 1 had closed, 5 did not respond, 9 declined to participate, and 14 participated, yielding a response rate of 50% for open facilities. Twenty-one percent of the facilities had preparations specifically for hurricanes. More than 70% of the facilities had lost electricity, heat, and telephone service, and one-half had evacuated. Twenty-one percent of the facilities reported not receiving any assistance and over one-half reported that relief resources did not meet their needs. Many LTCFs lacked plans specific to such a large-scale event. Since nearly all of the LTCFs in the region were affected, preexisting transportation and housing plans may have been inadequate. Future preparation could include hazard-specific planning and reliance on resources from a wider geographic area. Access to electricity emerged as a top priority.

2010-01-01

Based on the statistical targets established, the hydraulic model results suggest that an additional 2428 m2 or a 30-percent increase in suitable mussel habitat could be generated at the replacement-bridge site when compared to the baseline condition associated with the existing bridge at that same location. The study did not address the influences of substrate, acid mine drainage, sediment loads from tributaries, and surface-water/ground-water exchange on mussel habitat. Future studies could include methods for quantifying (1) channel–substrate composition and distribution using tools such as hydroacoustic echosounders specifically designed and calibrated to identify bed composition and mussel populations, (2) surface-water and ground-water interactions, and (3) a high-streamflow event.

1986-01-01

Theoretical estimates of supersonic nozzle performance have been compared to experimental test data for nozzles with an area ratio of 100:1 conical and 300:1 optimum contour, and 300:1 nozzles cut off at 200:1 and 100:1. These tests were done on a Hughes Aircraft Company 5 lbf monopropellant hydrazine thruster with chamber pressures ranging from 25 to 135 psia. The analytic method used is the conventional inviscid method of characteristic with correction for laminar boundary layer displacement and drag. Replacing the 100:1 conical nozzle with the 300:1 contoured nozzle resulted in an improvement in thrust performance of 0.74 percent at chamber pressure of 25 psia to 2.14 percent at chamber pressure of 135 psia. The data is significant because it is experimental verification that conventional nozzle design techniques are applicable even where the boundary layer is laminar and displaces as much as 35 percent of the flow at the nozzle exit plane.

1995-03-01

Nine hundred forty eight teenagers (600 females) from a public school of one of the poorest communities of Santiago were surveyed about knowledge and practices on sexuality and reproductive health. Twenty four percent of females and 40% of males did not talk about their problems at home, instead they talked preferentially with their friends. Half of the sample attributed a risk a pregnancy to the first sexual intercourse; 67% did not know the infertile phase of the menstrual cycle and 20% did not identify two sexually transmitted diseases. Sixty percent considered rhythm technique as a safe fertility control method, 60% of males and 50% of females considered masturbation as risky, 57% of males and 49% of females estimated that condoms could be reused and between 5 and 16% of the sample correctly identified AIDS modes of transmission. Fifty percent had a couple and 23% of males and 17% of females had a sexual intercourse in the last six months; of these, 45% of women and 27% of men used a contraceptive method. Four percent of women and 6% of men became involved in a pregnancy and 57% of these terminated in abortions. It is concluded that knowledge about sexuality and reproductive biology among low income teenagers is scanty.

The decline of official language minorities in Quebec and English Canada.

"This paper considers the evolution of French outside of Quebec and the English in Quebec.... The total historical set of national data on ethnicity, mother tongue, knowledge of official languages and home language [is first presented]. The 120 year stability showing French at around 30 percent of the national total is a function of compensating factors including high French fertility and high English immigration. During the 1960s both of these demographic supports disappeared and thus mobility across linguistic lines has become a particularly sensitive issue. "The picture with regard to French outside of Quebec has changed rather radically in the last thirty-five years. For instance, there was one French child to every nine in 1941 and one to every twenty-one children in 1976. While the English of Quebec were once represented in various parts of the province, their strength is now largely limited to the Montreal metropolitan area which includes 76 percent of the English mother tongue group. Outside of Montreal, the English amounted to 7.9 percent of Quebec's population in 1941 and 5.6 percent in 1976. The paper concludes with a discussion of the social factors that underlie these trends and their relevance to the models of institutional and territorial bilingualism." (summary in FRE) excerpt

Conservation of water for washing beef heads at harvest.

2010-03-01

The objective of this research was to develop methods to conserve water necessary to cleanse beef heads prior to USDA-FSIS inspection. This was to be accomplished by establishing a baseline for the minimum amount of water necessary to adequately wash a head and application of image analysis to provide an objective measure of head cleaning. Twenty-one beef heads were manually washed during the harvest process. An average 18.75 L (2.49 SD) and a maximum of 23.88 L were required to cleanse the heads to USDA-FSIS standards. Digital images were captured before and after manual washing then evaluated for percentage red saturation using commercially available image analysis software. A decaying exponential curve extracted from these data indicated that as wash water increased beyond 20 L the impact on red saturation decreased. At 4 sigma from the mean of 18.75 L, red saturation is 16.0 percent, at which logistic regression analysis indicates 99.994 percent of heads would be accepted for inspection, or less than 1 head in 15,000 would be rejected. Reducing to 3 sigma would increase red saturation to 27.6 percent, for which 99.730 percent of heads likely would be accepted (less than 1 in 370 would be rejected). Copyright 2009 Elsevier Ltd.

2011-01-01

We conducted a telephone survey of all patients referred to a realtime telemedicine consultation at the Centre for Telehealth in Bogotá. Over a six-month period, 281 teleconsultations were conducted, and we were able to retrieve telephone numbers for 156 patients. Of these, 121 patients (78%) agreed to answer the questionnaire. Eighty percent of the respondents were satisfied or very satisfied with the teleconsultation and 63% would use telemedicine again. Sixty-five percent thought that telemedicine improved their medical care. More than 50% believed that telemedicine had a positive effect in terms of medical care improvement, time- and cost-savings. Twenty-seven percent felt that teleconsultation was not as good as a traditional face-to-face consultation. Lack of familiarity with ICT did not appear to act as a major barrier to telemedicine, and cognitive factors may be more important in acceptability to patients and their satisfaction. The results of the present study may also be relevant to the poorest countries of the world, where two-thirds of the population live in rural areas.

To determine the bacterial contamination rate of the parent's cell phone and the effectiveness of anti-microbial gel in reducing transmission of bacteria from cell phone to hands. Cross-sectional study of cultures from the cell phone and hands before and after applying anti-microbial gel (n=50). All cell phones demonstrated bacterial contamination. Ninety percent had the same bacteria on the cell phone and their cleaned hands. Twenty two percent had no growth on their hands after applying anti-microbial gel after they had the same bacteria on the cell phone and hands. Ninety-two percent of parents were aware that cell phones carried bacteria, but only 38% cleaned their cell phones at least weekly. Bacterial contamination of cell phones may serve as vectors for nosocomial infection in the neonatal intensive care unit. Bacteria transmitted from cell phone to hands may not be eliminated using anti-microbial gel. Development of hand hygiene and cell phone cleaning guidelines are needed regarding bedside cell phone use.
