Published: June 2010

Abstract
Rhizobacteria play an important role in sustainable agriculture via plant growth and biological control of pests in a number of ecosystems. Understanding the interactions of crop rotation and rhizobacteria on peanut production is a critical research need. Development of a database on the rhizobacteria obtained from continuous and rotational fields of peanut was initiated in 1997 and terminated in 2000. Peanut was planted in monoculture for 4 yr. In rotational plots, peanut, cotton, corn, and peanut were planted in sequence. Rhizobacteria were isolated from the roots of crop plants grown in a Norfolk soil near Florence, SC. These isolates were identified by composition of fatty acids from gas chromatography analysis (GC/FAME). Arthrobacter and Bacillus were the major genera from non-rhizosphere soils. At initiation of this study in July 1997, the plots selected for continuous peanut had more diversity in rhizobacteria than those plots selected for rotation. In July 2000, rhizobacteria diversity was greater from peanut roots in the rotation cropping system than continuous peanut. Even though rhizobacteria diversity was greater in the rotation system, higher peanut yields were recorded in the continuous peanut system in 2000. Burkholderia spp. were always isolated from the peanut and other crop rhizospheres at each sampling date.
Peanut (Arachis hypogaea) Response to Agricultural and Power Plant By-Product Calcium
Authors: Grichar W. J. , Besler B. A. , Melouk H. A. 
Published: June 2010

Abstract
Field studies were conducted at three locations in the south Texas peanut growing region to compare regular agricultural calcium with power plant byproduct calcium applied at planting or peanut pegging to runner peanut at rates of 560 to 1680 kg/ha. Both calcium sources decreased Rhizoctonia and Pythium pod disease development up to 62% when compared with the non-treated control and resulted in a yield increase over the non-treated control of up to 25%. When Rhizoctonia or Pythium was not a problem, no increase in peanut yield over the non-treated control was noted with any calcium application. Peanut grade (Total Sound Mature Kernels + Sound Splits) was increased at one location with the use of both calcium sources. Calcium, magnesium, and potassium content of foliage, hull, and kernel tissue was variable and was not related to calcium source.

Abstract
Irrigated hectares for crop production in Georgia increased from 70,875 ha in 1970 to 587,250 in 2000. The majority of the increase was planted in peanut, corn, and cotton. In 1970, these crops accounted for 40,500 of Georgia's irrigated hectares, and in 2000, these crops totaled 465,750 irrigated hectares. Simultaneously, demand for water resources due to urban expansion and interstate litigation coupled with repeated drought are collectively threatening irrigation water supplies in the southeast U.S. peanut producing regions. A study was conducted during the 2001 to 2003 crop years to quantify the impacts of reduced irrigation amounts and different crop rotation sequences including peanut, corn, and cotton. On average, irrigated peanut pod yield was significantly increased by 906 kg/ha as compared to nonirrigated peanut yield. The affect of crop rotation on peanut yield was also significant. One year out of peanuts, in either corn or cotton, increased irrigated peanut yield an average of 1072 kg/ha over continuous peanut. Two years out of peanuts, in either corn or cotton, increased irrigated peanut yield an average of 2333 kg/ha over continuous peanut. In nonirrigated peanuts, crop rotation sequence had less affect on pod yield than did precipitation during the growing season.
Evaluation of Arachis Species and Interspecific Tetraploid Lines for Resistance to Aflatoxin Production by Aspergillus flavus
Authors: Xue H. Q. , Isleib T. G. , Stalker H. T. , Payne G. A. , OBrian G. 
Published: June 2010

Abstract
Anatoxins are carcinogenic and extremely toxic secondary metabolites produced primarily by two fungi, Aspergillus flavus Link ex Fries and A. parasiticus Speare. Elimination of aflatoxin contamination in peanut (Arachis hypogaea L.) is a high priority of the peanut industry. Resistant cultivars should be an effective and low-cost part of an integrated aflatoxin management program. To date, no cultivated peanut has been reported with stable high levels of resistance to aflatoxin production. Arachis species and interspecific tetraploid lines have been evaluated for resistance to several peanut diseases and insect pests, and highly resistant accessions have been reported. Seven accessions of A. cardenasii Krapov. and W.C. Gregory, 29 of A. duranensis Krapov. and W.C. Gregory, and 17 interspecific tetraploid lines derived from A. hypogaea × A. cardenasii were inoculated with A. flavus strain NRRL 3357 and analyzed for aflatoxin content after incubation. On average, A. duranensis and A. cardenasii accumulated significantly less aflatoxin than A. hypogaea checks. The mean difference between the two wild species was not significant. Arachis duranensis accessions PI 468319 (GKBSPSc 30073), PI 468200 (GKBSPSc 30064), and PI 262133 (GKP 10038 sl.); and A. cardenasii accessions PI 262141 (GKP 10017) and PI 475997 (KSSc 36018) had reduced levels of aflatoxin accumulation and should be valuable sources of resistance to aflatoxin contamination. Of the interspecific tetraploid lines, only GP-NC WS 2 supported aflatoxin production not significantly different from resistant parent A. cardenasii GKP 10017, and it appears to be a line with reduced capacity for aflatoxin accumulation.
Vertebral artery–posterior inferior cerebellar artery bypass using a radial artery graft for hemorrhagic dissecting vertebral artery aneurysms: surgical technique and report of 2 cases
Authors: Czabanka Marcus , Ali Muhammad , Schmiedek Peter , Vajkoczy Peter , Lawton Michael T. 
Published: June 2010

Endovascular occlusion of hemorrhagic dissecting aneurysms of the vertebral artery (VA) is not possible when the posterior inferior cerebellar artery (PICA) originates from the dissecting aneurysm or when the contralateral VA provides inadequate collateral blood flow to the distal basilar circulation. The authors introduce a VA-PICA bypass with radial artery interposition graft and aneurysm trapping as an alternative approach and describe 2 cases in which this bypass was used to treat hemorrhagic dissecting VA aneurysms.
The VA-PICA bypass is performed via a standard far lateral approach. An end-to-side anastomosis between the radial artery graft and the PICA at the level of the caudal loop is performed first, and an end-to-side anastomosis is performed between the V3 segment and the proximal end of the radial artery graft. A 56-year-old woman harbored a hemorrhagic dissecting VA aneurysm incorporating the origin of the PICA. Endovascular treatment failed, with aneurysm refilling on follow-up angiography. A 65-year-old man had a hemorrhagic dissecting VA aneurysm and a hypoplastic contralateral VA. Both patients were treated with the VA-PICA bypass and aneurysm trapping, with adequate filling of the PICA territory in the first patient and both the PICA territory and the basilar circulation in the second patient.
Vertebral artery–PICA bypass with radial artery interposition graft and subsequent trapping of the dissected VA segment is an alternative to occipital artery–PICA and PICA-PICA bypass for the treatment of hemorrhagic dissecting VA aneurysms that are not suitable for endovascular occlusion.
Gamma Knife surgery for pituitary adenomas: factors related to radiological and endocrine outcomes
Authors: Sheehan Jason P. , Pouratian Nader , Steiner Ladislau , Laws Edward R. , Vance Mary Lee 
Published: June 2010

Object
Gamma Knife surgery (GKS) is a common treatment for recurrent or residual pituitary adenomas. This study evaluates a large cohort of patients with a pituitary adenoma to characterize factors related to endocrine remission, control of tumor growth, and development of pituitary deficiency.

Methods
A total of 418 patients who underwent GKS with a minimum follow-up of 6 months (median 31 months) and for whom there was complete follow-up were evaluated. Statistical analysis was performed to evaluate for significant factors (p < 0.05) related to treatment outcomes.

Results
In patients with a secretory pituitary adenoma, the median time to endocrine remission was 48.9 months. The tumor margin radiation dose was inversely correlated with time to endocrine remission. Smaller adenoma volume correlated with improved endocrine remission in those with secretory adenomas. Cessation of pituitary suppressive medications at the time of GKS had a trend toward statistical significance in regard to influencing endocrine remission. In 90.3% of patients there was tumor control. A higher margin radiation dose significantly affected control of adenoma growth.
New onset of a pituitary hormone deficiency following GKS was seen in 24.4% of patients. Treatment with pituitary hormone suppressive medication at the time of GKS, a prior craniotomy, and larger adenoma volume at the time of radiosurgery were significantly related to loss of pituitary function.

Conclusions
Smaller adenoma volume improves the probability of endocrine remission and lowers the risk of new pituitary hormone deficiency with GKS. A higher margin dose offers a greater chance of endocrine remission and control of tumor growth.
Intimate Partner Violence: Screening and Intervention in the Health Care Setting
Authors: Roark Sybil V. 
Published: June 2010

Background:
The prevalence of intimate partner violence (IPV) has been documented in numerous populations and cultures. IPV is a universal social problem that affects individuals, families, and communities throughout the world. Research supports the idea that victims of IPV view health care providers as a source of help. However, nurses report feelings of inadequacy in their ability to screen for IPV.

Methods:
This quality improvement project was undertaken to increase awareness of IPV by educating nursing staff working in the health care setting. The educational program was evaluated through pretests and posttests. A universal IPV screening question was added to the hospital admission intake procedure. Through retrospective chart reviews before and after the educational session, screening for IPV by the nursing staff was evaluated by examination of disclosure rates and referral data. Populations served or affected include nurses and ultimately victims of IPV.

Results:
The findings support the idea that an educational program can increase nurses’ confidence and competency in screening for IPV. The results of chart review will determine whether there is a significant change in behavior relative to the increase in knowledge.

Conclusion:
Additional measures may be needed to enhance nurses’ screening and interventional work with patients regarding IPV victimization.
Developing a Nursing Personnel Policy to Address Body Art Using an Evidence-Based Model
Authors: Dorwart Shawna D. , Kuntz Sandra W. , Armstrong Myrna L. 
Published: June 2010

Background:
An increase in the prevalence of body art as a form of self-expression has motivated health care organizations to develop policies addressing nursing personnel’s body art.

Methods:
A systematic review of literature on body art was completed and a telephone survey of 15 hospitals was conducted to query existing policy statements addressing nursing personnel’s body art.

Results:
The literature established no prevalence of body art among nurses or effect of nurses’ body art. Of the 13 hospitals (86%) that shared their policy on body art, none provided a rationale or references to support their existing policies.

Conclusion:
A lack of published evidence identifying the effect of body art among nurses shifts the burden of determining care outcomes to the leadership of individual hospitals. Further research on patients’ perception of nursing personnel with visible body art, using an evidence-based model, is recommended.
Is Excimer Laser Corneal Surgery Appropriate After Resolution of Corneal Edema in Fuchs Dystrophy by Descemet Membrane Endothelial Keratoplasty?
Authors: Price Francis W. , Price Marianne O. , Guerra Frederico 
Published: June 2010

Purpose:
To report a case of apparent central corneal thinning diagnosed after treatment of Fuchs dystrophy by Descemet membrane endothelial keratoplasty (DMEK) and to discuss treatment options with laser refractive surgery.

Methods:
A pseudophakic patient with Fuchs dystrophy underwent DMEK, with removal of dysfunctional recipient endothelium and replacement with bare endothelium and Descemet membrane from a donor cornea. Subsequently, a standard preoperative evaluation for LASIK, including refraction, topography, Pentacam (Oculus Optikgeräte GmbH), and slit-lamp examination was performed.

Results:
After DMEK, refraction was +0.75 +2.50 × 115. Corneal topography did not show evidence of corneal ectasia or suspicion of keratoconus. Simulated keratometry was 43.03×40.49. Central corneal thickness was 481 μm by ultrasonic pachymetry. Pentacam evaluation of the anterior and posterior surfaces showed normal contours relative to a best-fit sphere on the anterior surface, but central elevation of 25 μm on the posterior surface. The typical increased central corneal thickness of Fuchs dystrophy could have masked a latent forme fruste keratoconus that became evident after the edema resolved with DMEK, or the central edema could have led to loss of stromal thickness causing the forward displacement of the posterior corneal surface.

Conclusions:
It is uncertain whether this eye is safe for LASIK or PRK correction of the residual refractive error. This finding of posterior surface forward displacement would be difficult to impossible to detect in an eye after Descemet stripping endothelial keratoplasty due to the addition of stromal tissue on the graft.
Asymmetric Resting Scapular Posture in Healthy Overhead Athletes
Authors: Oyama Sakiko , Myers Joseph B. , Wassinger Craig A. , Daniel Ricci R. , Lephart Scott M. 
Published: June 2010

Abstract

Context:
Observation of the scapular posture is one of the most important components of the physical examination in overhead athletes. Postural asymmetry is typically considered to be associated with injuries. However, asymmetry in the overhead athlete's scapula may be normal due to the dominant use of the limb.

Objective:
To quantify the differences in resting scapular posture between the dominant and nondominant sides in 3 groups of healthy overhead athletes (baseball pitchers, volleyball players, and tennis players) using an electromagnetic tracking device.

Design:
Cross-sectional design.

Setting:
University-based biomechanics laboratory.

Patients or Other Participants:
A total of 43 players participated, including 15 baseball pitchers, 15 volleyball players, and 13 tennis players. All participants were healthy college-aged men.

Intervention(s):
Bilateral 3-dimensional scapular kinematics with the arm at rest were measured using an electromagnetic tracking device.

Main Outcome Measure(s):
Bilateral scapular position and orientation were measured. Between-groups and between-sides differences in each variable were analyzed using separate analyses of variance.

Results:
In tennis players, the scapula was more protracted on the dominant side than on the nondominant side (P &lt; .05). In all overhead athletes, the dominant-side scapula was more internally rotated (P  =  .001) and anteriorly tilted (P  =  .001) than the nondominant-side scapula was.

Conclusions:
The dominant-side scapula of the overhead athletes was more internally rotated and anteriorly tilted than the nondominant-side scapula. The dominant-side scapula of the tennis players was more protracted than that on the nondominant side. Clinicians evaluating overhead athletes need to recognize that scapular posture asymmetry in unilateral overhead athletes may be normal. Our results emphasize the importance of the baseline evaluation in this population in order to accurately assess pathologic change in bilateral scapular positions and orientations after injury.
Isokinetic Peak Torque Ratios and Shoulder Injury History in Adolescent Female Volleyball Athletes
Authors: Stickley Christopher D. , Hetzler Ronald K. , Freemyer Bret G. , Kimura Iris F. 
Published: June 2010

Abstract

Context:
Few researchers have examined shoulder strength in adolescent volleyball athletes despite increasing levels of participation in this age group.

Objective:
To compare medial and lateral isokinetic peak torque of the rotator cuff among skill levels and between athletes with and without a history of shoulder injury.

Design:
Cross-sectional design.

Setting:
The Human Performance Lab and Athletic Training Lab.

Patients or Other Participants:
Thirty-eight female adolescent club volleyball athletes from 10 to 15 years of age (mean  =  13.02 ± 1.60 years).

Main Outcome Measure(s):
We measured concentric and eccentric peak torque of the medial and lateral rotators of the shoulder and calculated resultant cocking and spiking ratios based on peak torque values.

Results:
Athletes at higher skill levels had higher peak torque measurements in concentric and eccentric medial and lateral rotation compared with the athletes at lower skill levels. No differences in peak torque existed between participants with or without an injury history 6 months before the study. Strength ratios did not differ across skill levels, but previously injured participants produced lower eccentric medial rotation to concentric lateral rotation ratios compared with participants without a history of injury (P  =  .02). At the highest skill level, previously injured participants produced lower eccentric lateral rotation to concentric medial rotation ratios compared with participants without an injury history (P  =  .04).

Conclusions:
Differences in medial and lateral shoulder rotator strength ratios appear to be related more to injury prevalence than to absolute strength. Shoulder dysfunction related to strength ratio deficits also may exist in adolescent female volleyball athletes. Preventive shoulder strengthening programs focused on improving eccentric strength and correcting imbalances between medial and lateral rotators may be warranted for all female adolescent volleyball athletes.
Occlusive Dressings and the Healing of Standardized Abrasions
Authors: Beam Joel W. 
Published: June 2010

Abstract

Context:
Acute skin trauma during sport participation, resulting in partial-thickness abrasions, is common. The limited investigations focusing on the acute wound environment and dressing techniques and the subsequent lack of evidence-based standards complicate clinical wound care decisions.

Objective:
To examine the effects of occlusive dressings on healing of standardized, partial-thickness abrasions.

Design:
Controlled, counterbalanced, repeated-measures design.

Setting:
University laboratory.

Patients or Other Participants:
Sixteen healthy women (n  =  10) and men (n  =  6).

Intervention(s):
Four standardized, partial-thickness abrasions were inflicted. Film, hydrogel, and hydrocolloid occlusive dressings and no dressing (control) were applied. Participants returned on postwound days 1, 3, 5, 7, 10, and 14 for digital imaging. Wound healing time was measured by change in wound contraction (cm2) and change in wound color (chromatic red) and luminance in red, green, and blue color values.

Main Outcome Measure(s):
Wound contraction, color (chromatic red), and luminance.

Results:
A day-by-dressing interaction was found for wound contraction, color, and luminance. Post hoc testing indicated that the film and hydrocolloid dressings produced greater wound contraction than the hydrogel and no dressing on days 7 and 10. Film, hydrogel, and hydrocolloid dressings also resulted in greater wound contraction than the control on day 14. Hydrocolloid dressings produced smaller measures of color and greater measures of luminance than no dressing on day 7. Film, hydrogel, and hydrocolloid dressings also resulted in smaller measures of color and greater measures of luminance compared with no dressing on days 10 and 14.

Conclusions:
When compared with the control (no dressing), the film, hydrogel, and hydrocolloid occlusive dressings were associated with a faster healing rate of partial-thickness abrasions across time measured by wound contraction, color, and luminance. Overall, these data indicate that occlusive dressings were more effective in healing than no dressing was.
Epidemiology of Rare Injuries and Conditions Among United States High School Athletes During the 2005–2006 and 2006–2007 School Years

Published: June 2010

AbstractContext:Although more than 7 million athletes participate in high school sports in the United States, to date no nationally representative studies of rare injuries and conditions (RICs) exist. Rare injuries and conditions include eye injuries, dental injuries, neck and cervical injuries, and dehydration and heat illnesses.Objective:To describe the epidemiology of RICs sustained by high school athletes during the 2005–2006 and 2006–2007 school years.Design:Prospective cohort study.Setting:A nationally representative sample of 100 US high schools using an injury surveillance system, High School Reporting Information Online.Patients or Other Participants:Athletes participating in football, boys' soccer, girls' soccer, volleyball, boys' basketball, girls' basketball, wrestling, baseball, or softball at one of the 100 participating high schools.Main Outcome Measure(s):We reviewed all RICs to calculate injury rates and to identify potential risk factors and preventive measures.Results:A total of 321 RICs were sustained during 3 550 141 athlete-exposures (AEs), for an injury rate of 9.04 RICs per 100 000 AEs. This represents an estimated 84 223 RICs sustained nationally. The RICs accounted for 3.5% of all high school athletes' injuries. The most common diagnoses were neck and cervical injuries (62.0%, n  =  199) and dehydration and heat illnesses (18.7%, n  =  60). Football had the highest RIC rate per 100 000 AEs (21.2), followed by wrestling (15.2) and baseball (7.60). The RICs occurred at a higher rate in boys (12.4) than in girls (2.51) (rate ratio  =  4.93; 95% confidence interval  =  3.39, 7.18). The majority of RICs (67.3%, n  =  216) permitted athletes to return to play within 1 week of diagnosis.Conclusions:The RIC injury rates varied by sport and sex and represented almost 100 000 potentially preventable injuries to high school athletes. Because of the potentially serious consequences, future researchers must develop and implement more effective preventive measures to aid certified athletic trainers in decreasing the RIC incidence among high school athletes.
