    Prior studies suggest the cost of allograft anterior cruciate ligament (ACL) reconstruction is less than that for autograft reconstruction. Charges in these studies were influenced by patients requiring inpatient hospitalization. We therefore determined if allograft ACL reconstruction would still be less costly if all procedures were performed in a completely outpatient setting. We retrospectively reviewed 155 patients who underwent ACL reconstruction in an ambulatory surgery center between 2001 and 2004; 105 had an autograft and 50 had an allograft. Charges were extracted from itemized billing records, standardized to eliminate cost increases, and categorized for comparison. Surgeon and anesthesiologist fees were not included in the analysis. Groups were compared for age, gender, mean total cost, mean cost of implants, and several other cost categories. The mean total cost was 5465forallograftACLreconstructionand5465 for allograft ACL reconstruction and 4872 for autograft ACL reconstruction. There were no differences in complications between the two groups. Allograft ACL reconstruction was more costly than autograft ACL reconstruction in the outpatient setting. The cost of the allograft outweighs the increased surgical time needed for harvesting an autograft. Level II, economic and decision analyses.

    The performance of 8 parental groundnut genotypes (ICGS 76, CSMG 84-1, ICGS-44, ICGV 86031, TAG 24, GG 2, JL 220 and K 134) and 192 progenies was evaluated in Udaipur, Rajasthan, India, during 2000 (rainy season). The top 20 genotypes for kernel yield were identified by trait-based (9) and empirical (11) selections. For these genotypes, a kernel yield of 3411-4662, harvest index (HI) of 0.39-0.47, transpiration efficiency (TE) of 2.01-2.16 g/kg, and transpiration level of 377-492 mm were recorded. JAL 17, JUG 11, ICR 39, ICR 23 ad JAL 24 showed a significant improvement (from 12.7 to 28.1%) in kernel yield over the parent with the highest yield (TAG 24, 3639 kg/ha). Relative to TAG 24, higher HI (by 0.4-3.2%), TE (by 1.2%) and T (by 10.5-27.66%) were observed in 4, 3 and 5 of these genotypes. JAL 17, ICR 39 and ICR 23 showed significant increases in all 3 traits over the control

    Inspired by BIO2010 and leveraging institutional and external funding, Truman State University built an undergraduate program in mathematical biology with high-quality, faculty-mentored interdisciplinary research experiences at its core. These experiences taught faculty and students to bridge the epistemological gap between the mathematical and life sciences. Together they created the infrastructure that currently supports several interdisciplinary courses, an innovative minor degree, and long-term interdepartmental research collaborations. This article describes how the program was built with support from the National Science Foundation's Interdisciplinary Training for Undergraduates in Biology and Mathematics program, and it shares lessons learned that will help other undergraduate institutions build their own program

    Abstract Milk fat contains 400 vital fatty acids beneficial for human health. Special attention is given to fatty acids (FAs) that could play a positive role for human health; such are butyric, oleic acid, caproic, caprylic and capric acids. Keeping the medicinal properties of milk fatty acids in consideration, goat milk samples were analyzed for estimation of fatty acid contents in Indian goat milk by using gas chromatography. Analysis of goat milk samples revealed the highest concentration saturated fatty acids (SFA) out of total milk fatty acids (FA) with an average of 69.55 g/100g of fatty acid methyl ester (FAME) ranging from 43.26 to 88.05g/100g of FAME. Within saturated fatty acid the major contribution was given by palmitic (C16:0) 26.99% followed by myristic (C14:0) 11.77%, stearic (C18:0) 7.66% and capric (C10:0) 6.75% respectively. The concentration of short chain fatty acids (SCFAs, C4 to C10) was found to be 13.51 g/100g varying from 2.23 to 33.63 g/100g of FAME. Whereas the concentration of medium chain fatty acids (MCFAs , C12to C15) was 20.05% varying from 7.470 to 45.27 g/100 g of FAME and Long chain FA (LFA, C16 to C24) was 35.08% varying from 4.77 to 51.22 g/100g of FAME. The average concentration of unsaturated fatty acids (UFAs) was 28.50 g/100grm of FAME varying from 10.44 to 45.74 g/100g of FAME which includes monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) with an average of 24.57 g/100g of FAME ranges varying from 4.79 to 39.40 g/100g of FAME and 3.96 g/100g of FAME ranges varying from 0.5928 to 18.30g/100 g of FAME, respectively

    Injury Risk Estimation Expertise Assessing the ACL Injury Risk Estimation Quiz

    Background: Available methods for screening anterior cruciate ligament (ACL) injury risk are effective but limited in application as they generally rely on expensive and time-consuming biomechanical movement analysis. A potential efficient alternative to biomechanical screening is skilled movement analysis via visual inspection (ie, having experts estimate injury risk factors based on observations of athletes’ movements). Purpose: To develop a brief, valid psychometric assessment of ACL injury risk factor estimation skill: the ACL Injury Risk Estimation Quiz (ACL-IQ). Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: A total of 660 individuals participated in various stages of the study, including athletes, physicians, physical therapists, athletic trainers, exercise science researchers/students, and members of the general public in the United States. The ACL-IQ was fully computerized and made available online (www.ACL-IQ.org). Item sampling/reduction, reliability analysis, cross-validation, and convergent/discriminant validity analysis were conducted to optimize the efficiency and validity of the assessment. Results: Psychometric optimization techniques identified a short (mean time, 2 min 24 s), robust, 5-item assessment with high reliability (test-retest: r = 0.90) and consistent discriminability (average difference of exercise science professionals vs general population: Cohen d = 1.98). Exercise science professionals and general population individuals scored 74% and 53% correct, respectively. Convergent and discriminant validity was demonstrated. Scores on the ACL-IQ were most associated with ACL knowledge and various cue utilities and were least associated with domain-general spatial/decision-making ability, personality, or other demographic variables. Overall, 23% of the total sample (40% exercise science professionals; 6% general population) performed better than or equal to the ACL nomogram. Conclusion: This study presents the results of a systematic approach to assess individual differences in ACL injury risk factor estimation skill; the assessment approach is efficient (ie, it can be completed in\3 min) and psychometrically robust. The results provide evidence that some individuals have the ability to visually estimate ACL injury risk factors more accurately than other instrument-based ACL risk estimation methods (ie, ACL nomogram). The ACL-IQ provides the foundation for assessing the efficacy of observational ACL injury risk factor assessment (ie, does simple skilled visual inspection reduce ACL injuries?). It also provides a representative task environment that can be used to increase our understanding of the perceptual-cognitive mechanisms underlying observational movement analysis and to improve injury risk assessment performance

    <p>Abstract</p> <p>Background</p> <p>Occupational injuries among flight attendants have not been given appropriate attention in Sri Lanka. The purpose of this study was to estimate the incidence of onboard injury among Sri Lankan flight attendants and to describe the determinants of onboard injury.</p> <p>Methods</p> <p>A descriptive cross-sectional study was carried out among Sri Lankan flight attendants. All flight attendants undergoing their annual health and first aid training were invited to participate. Flight attendants who flew continuously for a six-month period prior to data collection were included in the study sample. Recall history of injuries for a period of six months was recorded.</p> <p>Results</p> <p>The study sample consisted of 98 (30.4%) male and 224 (69.6%) female flight attendants. The mean age of the study sample was 31 years (SD = 8) and the average duration of service was 10 years (SD = 7). A total of 100 onboard falls, slips or trips in the previous six months were reported by 52 (16.1%) respondents. Of the total sample, 128 (39.8%) cabin crew members reported an injury in the six months preceding the study. This represents a total injury incidence of 795 per 1000 person per year. The leading causes of injury was pulling, pushing or lifting (60.2%). The commonest type of injuries were strains and sprains (52.3%). Turbulence related injuries were reported by 38 (29.7%) flight attendants. The upper limbs (44.5%) and the back (32%) were the commonest sites affected. After controlling for other factors, female flight attendants had 2.9 times higher risk (95% CI 1.2–7.2) of sustaining and injury than males. Irrespective of sex, body weight less than 56 kilograms (OR 2.9, 95% CI 1.4–5.8) and less than seven years of on board experience (OR 10.5, 95% CI 3.6–31.0) were associated with higher risk of injury.</p> <p>Conclusion</p> <p>Work related injury is a major occupational hazard to flight attendants. Appropriate preventive strategies are required to minimize them.</p
