Authors: George Steven Z. , Valencia Carolina , Beneciuk Jason M. 
Published: April 2010

Study Design Validity and test-retest reliability of questionnaires related to the fear-avoidance model (FAM). Objectives To investigate test-retest reliability, construct redundancy, and criterion validity for 4 commonly used FAM measures. Background Few studies have reported psychometric properties for more than 2 FAM measures within the same cohort, making it difficult to determine which specific measures should be implemented in outpatient physical therapy settings. Methods Fifty-three consecutive patients (mean age, 44.3 ± 18.5 years) with chronic low back pain participated in this study. Data were collected with validated measures for FAM constructs, including the Fear-Avoidance Beliefs Questionnaire (FABQ), Fear of Pain Questionnaire (FPQ), Tampa Scale for Kinesiophobia, and Pain Catastrophizing Scale. Validated measures were used to investigate criterion validity of the FAM measures, including the Patient Health Questionnaire for depression, the numerical rating scale for pain intensity, the Physical Impairment Scale for physical impairment, and the Oswestry Disability Questionnaire for self-report of disability. Test-retest reliability of the FAM measures was determined with intraclass correlation coefficients (ICC2, 1) for total questionnaire scores at baseline and 48 hours later. Construct redundancy was determined with Pearson correlation coefficients for FAM measures. Criterion validity was assessed by 4 separate multiple regression models that included age, sex, and employment status as covariates. Depression, pain intensity, physical impairment, and disability were the dependent variables for these analyses. Results Test-retest ICC coefficients ranged from 0.90 to 0.96 for all FAM questionnaires. The FAM measures were significantly correlated with each other, with the only exception being that the FPQ was not correlated with the FABQ work scale. In the multiple regression models, the Pain Catastrophizing Scale contributed additional variance to depression. The FABQ physical activity scale contributed additional variance to pain intensity and disability. The FABQ work scale contributed additional variance to physical impairment and disability. No other FAM measures contributed to these regression models. Conclusion These data suggest that 4 commonly used FAM measures have similar test-retest reliability, with varying amounts of construct redundancy. The criterion validity analyses suggest that measurement of fear-avoidance constructs for patients seeking outpatient physical therapy with chronic low back pain should include the Pain Catastrophizing Scale and the FABQ.

Published: April 2010

Study Design A case report and literature review. Background Optimizing clinical outcomes following lumbar disc surgery is a research priority; however, relatively little attention has been paid to the postoperative management of this population. The transversus abdominis and lumbar multifidus (LM) muscles appear to play a unique role in lumbar spine stability, and may relate to clinical outcome following lumbar disc surgery. The purpose of this case report was to describe the preoperative LM morphology, clinical outcome, and change in transversus abdominis and LM muscle activation in a patient following lumbar disc surgery and motor control exercise initiated in the early postoperative period. Case Description A 29-year-old female underwent an 8-week postoperative rehabilitation program emphasizing motor control exercises to restore trunk muscle function 10 days following lumbar disc surgery. Outcomes The patient experienced clinically important improvements in pain and disability following the postoperative rehabilitation program. Substantial improvements in muscle activation were observed of the transversus abdominis and the LM at the L4-5 level. Minimal change in LM activation and a higher proportion of intramuscular fat was observed at the L5-S1 level. Discussion This case report represents limited evidence regarding the feasibility of instituting a rehabilitation program in the early postoperative period following lumbar disc surgery. Improvements in clinical status and muscle function were observed, and a differential change in muscle activation between the L4-5 and L5-S1 levels was noted. The literature regarding rehabilitation following lumbar disc surgery, as well as the neuro-muscular changes observed in this population, was reviewed. Additionally, a novel method of examining LM morphology was described and suggestions were made for directions of future research. Level of Evidence Therapy, level 4.

Published: April 2010

AbstractObjective. Previous studies on weight gain in pregnancy suggested that maternal weight on average increased by 0.5–2.0 kg in the first trimester of pregnancy. This study examined whether mean maternal weight or body composition changes in the first trimester of pregnancy. Design. Prospective observational study. Population. We studied 1,000 Caucasian women booking for antenatal care in the first trimester of pregnancy. Setting. Large university teaching hospital. Methods. Maternal height and weight were measured digitally in a standardized way and Body Mass Index (BMI) was calculated. Maternal body composition was measured using segmental multifrequency Bioelectrical Impedance Analysis (BIA). Sonographic examination confirmed the gestational age and a normal ongoing singleton pregnancy in all subjects. Main outcome measures. Maternal weight, maternal body composition. Results. The mean BMI was 25.7 kg/m2 and 19.0% of the women were in the obese category (≥30.0 kg/m2). Cross‐sectional analysis by gestational age showed that there was no change in mean maternal weight, BMI, total body water, fat mass, fat‐free mass or bone mass before 14 weeks gestation. Conclusions. Contrary to previous reports, mean maternal weight and mean body composition values remain unchanged in the first trimester of pregnancy. This has implications for guidelines on maternal weight gain during pregnancy. We also recommend that calculation of BMI in pregnancy and gestational weight gain should be based on accurate early pregnancy measurements, and not on self‐reported or prepregnancy measurements.

Background: Complete resection of hypervascular metastatic tumors is often complicated by massive intraoperative blood loss. Purpose: To assess the technical success and clinical effectiveness of transcatheter arterial embolization (TAE) of hypervascular metastatic tumors of long bones to reduce blood loss during orthopedic surgery. Material and Methods: From January 2000 to September 2009, 25 patients (M:F=13:12; mean age 58.3 years) were treated with TAE of metastatic bone tumors before elective, orthopedic surgery. In all cases, the indication for TAE was preoperative devascularization. Technical success, defined as obliteration of tumor staining to 70% or more, requirement for red blood cell transfusion within 24 h following surgery, and hematologic parameters, i.e. the hemoglobin, hematocrit, and erythrocyte counts before and after surgery, were obtained. Results: The technical success rate was 96% (24/25 patients). Gelatin sponge particles ( n=21) or polyvinyl alcohol particles ( n=4) were used as embolic materials. The mean amount of red blood cell transfusion within the 24 h following surgery was 1.91 units (range 0–6) in the 23 patients with technically successful TAE and who underwent surgery within 3 days after TAE. In 22 patients with technically successful TAE and available hematologic data, the mean gaps in the hemoglobin, hematocrit, and erythrocyte counts before and after operation were 1.22 g/dl, 4.07%, and 0.45×106/mm3, respectively. Conclusion: Preoperative TAE is technically successful and clinically effective to minimize intraoperative and postoperative bleeding in patients with hypervascular metastasis to long bones.

Abstract
Arachis spp. PI 262794, 262817, 421707, 468141, 468144, 468170, 468174, 468345, 468363, 468366, 468370 and 468371 were resistant to mechanical infection with peanut mottle (PMV), peanut stripe (PStV) and tomato spotted wilt viruses(TSWV). PI 262817, 421707 and 468363 (all in the section Rhizomatosae) did not show infection after graft inoculation with tissue singly infected with either PMV, PStV or TSWV. When three scions, each infected with one of the viruses, were grafted on the same plant, only PI 262817 remained virus free.

Published: April 2010

Abstract
Five runner peanut (Arachis hypogaea L.) cultivars were treated with four dinitroaniline herbicide treatments or a postemergence herbicide treatment to determine the effect on pod yield and grade, percentage sound mature kernels + sound splits (SMK+SS). No yield differences due to the dinitroaniline herbicide treatments were noted in the three year study. Southern Runner and GK-7 were higher in yield in one of the three test years, however, no cultivar yield differences were noted in the other two years. Grades were lower with pendimethalin in the three years; grades of trifluralin, ethalfluralin and benefin-treated peanuts were variable from year to year.
A Note on the Earliness of Offspring from Crosses Among Five Short Growth-Duration Peanut Lines1
Authors: N'Doye O. , Smith O. D. 
Published: April 2010

Abstract
Short growing seasons, such as those that occur in semi-arid regions of West Africa, prevent peanut (Arachis hypogaea L.) from maturing properly. Immature fruit lowers peanut quality and yield, and enhances growth of toxin-producing molds during storage. Germplasm with expressed accelerated development for use as parents in developing early maturing (75 day) cultivars suited for production in those regions is limited. Information on the genetic variability for earliness among the very early maturing candidate parental lines is lacking. Five erect, early maturing peanut lines of diverse origin were crossed in diallel; and parent, F1, and F2 generation progeny from plantings on four dates were compared. Measures were made on a plant basis for the number of days from planting to emergence (DEMR), number of days to first (DONE), fifth (DFIV), tenth (DTEN), fifteenth (DFIFT), twentieth (DTWEN), and twenty-fifth (DTW5) flower; and, following early digging, for number of full-size pods (FULL), number of mature pods (NUMP), and percent mature pods (%MP). F2 segregates that emerged and flowered earlier than parental and F1 plants were noted. Coefficients of correlation for DEMR and flowers DONE to DTW5 with FULL, NUMP, and %MP were negative; the association being stronger with FULL and NUMP than with %MP. R values were highest for DTW5 with FULL and NUMP, and decreased progressively with lower flower numbers (longer time intervals between measures) which indicated that the developmental rate was not consistent among genotypes. Mean broad sense heritability estimates for the traits examined ranged from 36 to 45%. H estimates for specific reproductive stages on individual crosses ranged from 4 to 65%, but for no cross were the H values consistently high for all measures. Both general and specific combining abilities were insignificant. The frequency of F2 plants with FULL and NUMP extending the range of their parents was low. Opportunity for selection of recombinants that would produce large numbers of full-size and mature pods faster than that of the parental lines might be possible in some of the crosses. The extent of potential decrease in growth duration could not be estimated from this study.
Further Studies On The Inheritance Of Fatty Acid Composition In Peanut1
Authors: Knauft D. A. , Moore K. M. , Gorbet D. W. 
Published: April 2010

Abstract
Oleic and linoleic acid together constitute about 80% of the fatty acid composition in peanut oil. Increasing the ratio of oleic to linoleic acid will improve the keeping quality of peanut oil. A University of Florida breeding line, designated F435, averages 80% oleic acid and 2% linoleic acid. Initial genetic studies of this fatty acid composition showed that a single recessive gene controlled the trait in two genetic backgrounds and a second recessive gene was necessary for expression in a third background. Further studies have shown monogenic inheritance in 12 parental backgrounds and digenic inheritance in one background. This suggests that either one of the two recessive genes may be common in peanut germplasm, and that crosses could be expected to segregate in simple monogenic ratios. When the proportion of genes from F435 is reduced through backcrossing to less than 0.8%, fatty acid composition remains similar to the original F435 line. Organoleptic and agronomic characteristics do not appear affected by the fatty acid composition change. Given the simple inheritance, lack of background genetic effects, and lack of apparent undesirable linkages, incorporation of high oleic acid into peanut cultivars should be straightforward.
Isozyme Analyses of Arachis Species and Interspecific Hybrids1
Authors: Lacks G. D. , Stalker H. T. 
Published: April 2010

Abstract
To better estimate diversity within the cultivated peanut, germplasm representing 33 South American peanut accessions from six countries was evaluated for isozyme polymorphisms. Only three of 18 isozymes—glutamate oxaloacetate transaminase (GOT), isocitrate dehydrogenase (IDH), and phosphohexose isomerase (PHI) — were consistently variant, each displaying two banding patterns. The variant banding patterns were observed in 18, 9, and 9% of the genotypes for GOT, IDH, and PHI, respectively. Isozyme variation in A. hypogaea could not be associated with subspecies or botanical variety. Thirty interspecific hybrids and their parents were also evaluated for isozyme polymorphisms. Flower tissues showed variations for the following isozymes: alanine aminopeptidase (AAP), arginine aminopeptidase (AMP), glutamate oxaloacetate transaminase (GOT), malate dehydrogenase (MDH), and phosphohexose isomerase (PHI). A specific PHI band pattern was observed in all three hybrid lines with early leafspot resistance, as well as three of the four lines associated with high yield. For seed tissue, the absence of a fast-moving leucine aminopeptidase (LAP) band was associated with three of the four high-yielding lines. A comparison of flower and seed isozyme banding patterns revealed that the banding pattern was different for GOT, IDH, LAP, MDH, and PHI. IDH and MDH were variant in seeds but not flowers, and GOT was more polymorphic in flowers than seeds. The investigation indicates that isozymes may serve as molecular markers for interspecific hybrid identification and gene introgression to the A. hypogaea genome, and possibly for identifying lines with useful resistances.

Published: April 2010

Abstract
The apparent disease progress of spotted wilt, caused by tomato spotted wilt virus, was monitored in the three component lines of Southern Runner peanut (Arachis hypogaea L.), and in cultivars Southern Runner, Florunner and GK-7 in the field in 1990-1992. In all three years, final incidence and area under the disease progress curves were similar among Southern Runner and all three component lines. Final incidence of spotted wilt in Southern Runner and all component lines was less than for Florunner in all three years. AUDPC values were lower in Southern Runner and two of the three component lines than in Florunner. Incidence and AUDPC of spotted wilt in GK-7 was intermediate between Florunner and Southern Runner and its individual components. Disease increase was linear in all component lines and cultivars. Rate of disease progress was similar among Southern Runner and the three component lines. Disease progressed more slowly in Southern Runner and the component lines than in Florunner.

Published: April 2010

Abstract
Cercospora arachidicola Hori is one of the most important foliar pathogens worldwide that limits peanut production in farmers' fields. Earlier screening trials allowed us to identify lines with field resistance to early leafspot. In order to determine the components of resistance of these lines and other lines reported to be resistant elsewhere, 19 peanut genotypes (Arachis hypogaea L.) were evaluated by the detached leaf technique using an isolate of Cercospora arachidicola from the ICRISAT Center in India. Significant differences were observed among genotypes for all components of resistance included in the study. With a few exceptions, early leafspot- resistant genotypes (ICG nos. 8298, 6902, 6284, 1703, 10900, 7878, 9989 and 10920) exhibited longer incubation periods, reduced sporulation, smaller lesion diameters and lower infection frequencies than susceptible lines. Genotypes ICG 8298 and ICG 6902 were the most resistant, while ICG nos. 221, 7827 and 6340 were the most susceptible to early leafspot. A few lines had resistant reactions to some components but susceptibility to others.

Published: April 2010

Abstract
Field experiments were conducted in 1991 and 1992 in Georgia to determine the efficacy of DPX-PE350 when applied either preplant incorporated (PPI), preemergence (PRE), and early postemergence (EPOST) at rates of 40, 80, or 120 g ae ha-1 for weed control in peanut. Species evaluated included coffee senna [Cassia occidentalis (L.)], Florida beggarweed [Desmodium tortuosum (Sw.) DC.], prickly sida (Sida spinosa L.), smallflower morningglory [Jacquemontia tamnifolia (L.) Griseb.], sicklepod (Cassia obtusifolia L.), and yellow nutsedge (Cyperus esculentus L.). Sicklepod was controlled better with either PPI or PRE applications than with EPOST. Coffee senna control was more consistent with DPX-PE350 applied EPOST. DPX-PE350 controlled prickly sida and smallflower morningglory regardless of application method and rate. DPX-PE350 did not control Florida beggarweed when soil applied. PPI applications were more injurious to peanut than PRE or EPOST applications. Peanut yields tended to decrease as DPX-PE350 rates increased.
Effects of Chlorpyrifos on Pod Damage, Disease Incidence, and Yield in Two Peanut Fungicide Programs1
Authors: Chapin J. W. , Thomas J. S. 
Published: April 2010

Abstract
The benefits of chlorpyrifos (Lorsban 15G) soil insecticide treatment in standard (chlorothalonil) and developmental (tebuconazole) peanut fungicide programs were compared in five field tests over a 3-yr period. Chlorpyrifos treatment reduced incidence of southern stem rot (Sclerotium rolfsii) and insect pod injury, while increasing yield in the standard fungicide program. In contrast, chlorpyrifos treatment did not measurably affect stem rot incidence or yield in the tebuconazole program, and insect pod injury was reduced in only one of three years. Tebuconazole reduced Rhizoctonia limb rot (R. solani AG-4) and stem rot incidence, and decreased pod injury relative to the standard chlorothalonil program. Tebuconazole increased yield 804 kg/ha (716 lb/ac) over the standard fungicide. Chlorpyrifos increased yield 503 kg/ha (448 lb/ac) for a net return of $315/ha ($128/ac) in the standard fungicide program. However, in the developmental program, chlorpyrifos increased yield only 79 kg/ha (70 lb/ac) for a net return of -$2/ha (-$1/ac). Labeling of ergosterol biosynthesis inhibitor (EBI) fungicides such as tebuconazole would significantly affect peanut insect management in some production areas by reducing the economic incentive for preventative treatments of organophosphate insecticides.
Evaluation of Field Inoculation Techniques for Screening Peanut Genotypes for Reaction to Preharvest A. flavus Group Infection and Aflatoxin Contamination1
Authors: Will M. E. , Holbrook C. C. , Wilson D. M. 
Published: April 2010

Abstract
Efforts are being made to screen peanut (Arachis hypogaea L.) genotypes for resistance to invasion of seed by the Aspergillus flavus (Link ex Fries) group fungi and subsequent contamination by aflatoxins. Field inoculation studies are needed to develop reliable screening techniques that insure infection of susceptible peanut seed by the A. flavus group fungi and minimize the number of escapes. The objectives of this study were to evaluate the effects of A. parasiticus (Speare) inoculum formulation and timing of application on shell and seed colonization and aflatoxin contamination. Soil population densities of A. flavus and plant survival were also measured. Plots were inoculated using various rates either at-plant or at mid-bloom of an organic-matrix infested with A. parasiticus NRRL 2999, and/or using an aqueous conidial suspension of the fungus. Mid-bloom inoculation produced an increase of A. flavus group population densities in the soil. There were no statistical differences between treatments in aflatoxin content, or colonization of shells or seed. At-plant inoculation was associated with reduced plant emergence or survival. Inoculation at mid-bloom with the organic-matrix resulted in peanuts that ranked high in aflatoxin content. There were no correlations between aflatoxin content, colonization of seed or shells, and population densities of A. flavus in soil. Inoculation at mid-bloom with the organic-matrix, resulting in greater soil population densities and relatively higher aflatoxin levels, was an effective method to use in screening for resistance to invasion by A. flavus group fungi and contamination by aflatoxins.
Chloroacetamide Herbicides and Chlorimuron Do Not Predispose Peanut (Arachis hypogaea) to Stem Rot (Sclerotium rolfsii)1
Authors: Johnson W. Carroll , Brenneman Timothy B. , Mullinix Benjamin G. 
Published: April 2010

Abstract
Field studies were conducted from 1991 through 1993 at Plains, GA to determine the effect of chloroacetamide herbicides and chlorimuron on incidence of stem rot in peanut. The experimental site had a cropping history of more than 25 yr in continuous plantings of peanut and extremely high incidence of stem rot. Incidence of stem rot and peanut yield were not affected (P≤0.05) by chloroacetamide herbicides in 1991, 1992, and 1993. Chlorimuron applied 60 d after emergence had no effect on stem rot incidence or peanut yield. Paired plots treated with thifluzamide had very low stem rot incidence and 27% greater peanut yields. Based on these studies, neither chloroacetamide herbicides nor chlorimuron predisposed peanut to stem rot.
