- Abstract
CASE STUDY: George, a 55-year-old retired businessman with a diagnosis of myelofibrosis, underwent an allogeneic stem cell transplantation from his human leukocyte antigen-matched brother in June 2006. He was admitted to the hospital for a possible flare of graft-versus-host disease (GVHD) of the gut. His medications included tacrolimus, budesonide, and bechlamethasone for immunosuppression and pantoprazole. A stool sample was positive for Clostridium difficile toxin A on October 31, 2006, and he was started on oral metronidazole. [ABSTRACT FROM AUTHOR]

- Abstract
Background: The Northern bobwhite (Colinus virginianus) is an economically important, and popular game bird in North America. Northern bobwhites have experiencing declines of > 3.5% annually in recent decades due to several factors. The eyeworm Oxyspirura petrowi is a nematode parasite frequently found in the eyes of bobwhites. Although reported frequently in wild bobwhites, there is no research to understand the host-parasite mechanism. Hence, it is important to investigate mechanisms of eyeworm invasion and immune modulation in bobwhite. Cytokine gene expression using RT-PCR is widely used to identify the innate immune response of a host to an infection., Methodology: In this study, we evaluated ten reference genes (HMBS, RPL19, RPL32, RPS7, RPS8, TATA, SDHA, YWHAZ, GAPDH, and ACTB) for their stability across three tissues (liver, spleen, and caecal tonsils) of control and O. petrowi infected Northern bobwhites. Primer efficiency and reference genes stability were assessed using GeNorm, NormFinder, and BestKeeper., Results: Expression of these reference genes with respect to O. petrowi infection in bobwhites showed RPL32 and HMBS were the most stable genes in the liver, HMBS and SDHA were the most stable genes in the spleen, and HMBS and YWHAZ were equally stable reference genes in the caecal tonsils., Conclusion: Based on the geometric mean of all three analyses, our results indicate that the combination of RPL32 and HMBS for the liver, HMBS and SDHA for the spleen, and YWHAZ and HMBS for caecal tonsils might be used as reference genes for normalization in gene expression investigations on Northern bobwhites., (© 2024.

- Abstract
The Northern Bobwhite (Colinus virginianus) is an economically important game bird within the Rolling Plains Ecoregion. Within this region, bobwhite is experiencing extreme cyclic population fluctuations which are resulting in a net decline in total population. It is suspected that within this region two helminth parasites, an eyeworm (Oxyspirura petrowi) and a cecal worm (Aulonocephalus pennula), are contributing to this phenomenon. However, this has been difficult to study as the primary mode of investigation would be the deployment of anthelmintic treatment. Unfortunately, no registered treatments for wild bobwhite currently exist. Thus, utilizing an anthelmintictreatment for wild bobwhite would require registration of that treatment with the U.S. Food and Drug Administration (FDA). As bobwhite are game birds that are hunted, they are considered food-producing animals to the FDA, and as such require the assessment for the withdrawal of the drug residues to be assessed for human food safety. In this study, we optimized and validated a bioanalytical method for the quantification of fenbendazole sulfone in bobwhite following the U.S. FDA Center for Veterinary Medicine Guidance for Industry #208 [VICH GL 49 (R)] for assessment of fenbendazole sulfone drug residue in Northern bobwhite liver. The official method for quantifying fenbendazole sulfone in domestic chicken (Gallus gallus) was adapted for use in bobwhite. The validated method quantitation range is 2.5-30 ng/mL for fenbendazole with an average recovery of 89.9% in bobwhite liver., (© 2023 John Wiley & Sons Ltd.)

- Abstract
Objective: To describe nursing symptom management of depression and anxiety in patients with cancer., Data Sources: These include journal articles, online resources, and personal experience in providing mental health care to cancer survivors with depression and/or anxiety., Conclusion: Nurses can provide emotional support for patients with cancer and depression or anxiety. Nurses can become aware of nonpharmacologic and pharmacologic treatment for depression and anxiety to help patients decrease their emotional distress. Nurses can also refer patients with cancer to psychiatric professionals and emotional support programs., Implications for Nursing Practice: Nurses do not have to be experts in psychiatry to manage symptoms of depression and anxiety in patients with cancer. Nurses can listen empathically, guide patients in relaxation techniques, and advocate if they need psychotropic medications or psychiatric referrals., (Copyright © 2022 Elsevier Inc.

- Abstract
A Society of Environmental Toxicology and Chemistry (SETAC) Focused Topic Meeting (FTM) on the environmental management of per- and polyfluoroalkyl substances (PFAS) convened during August 2019 in Durham, North Carolina (USA). Experts from around the globe were brought together to critically evaluate new and emerging information on PFAS including chemistry, fate, transport, exposure, and toxicity. After plenary presentations, breakout groups were established and tasked to identify and adjudicate via panel discussions overarching conclusions and relevant data gaps. The present review is one in a series and summarizes outcomes of presentations and breakout discussions related to (1) primary sources and pathways in the environment, (2) sorption and transport in porous media, (3) precursor transformation, (4) practical approaches to the assessment of source zones, (5) standard and novel analytical methods with implications for environmental forensics and site management, and (6) classification and grouping from multiple perspectives. Outcomes illustrate that PFAS classification will continue to be a challenge, and additional pressing needs include increased availability of analytical standards and methods for assessment of PFAS and fate and transport, including precursor transformation. Although the state of the science is sufficient to support a degree of site-specific and flexible risk management, effective source prioritization tools, predictive fate and transport models, and improved and standardized analytical methods are needed to guide broader policies and best management practices.

- Abstract
Organic fluorinated compounds have been detected in various environmental media and biota. Some of these compounds are regulated locally (e.g., perfluorononanoic acid maximum contaminant level in drinking water by the New Jersey Dept. of Environmental Protection), nationally (e.g., perfluorooctanoic acid maximum acceptable concentration in drinking water by Health Canada), or internationally (e.g., Stockholm Convention on Persistent Organic Pollutants). Globally, regulators and researchers seek to identify the organic fluorinated compounds associated with potential adverse effects, bioaccumulation, mobility, and persistence to manage their risks, and, to understand the beneficial attributes they bring to products such as first responder gear, etc. Clarity is needed to determine the best analytical method for the goal of the analyses (e.g., pure research or analysis to determine the extent of an accidental release, monitoring groundwater for specific compounds to determine regulatory compliance, and establish baseline levels in a river of organic fluorinated substances associated with human health risk prior to a clean-up effort). Analytical techniques that identify organic fluorine coupled together with targeted chemical analysis will yield information sufficient to identify public health or environmental hazards.

- Abstract
Many recent studies have been focused on prevalence and impact of two helminth parasites, eyeworm Oxyspirura petrowi and caecal worm Aulonocephalus pennula, in the northern bobwhite quail (Colinus virginianus). However, few studies have attempted to examine the effect of these parasites on the bobwhite immune system. This is likely due to the lack of proper reference genes for relative gene expression studies. Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) is a glycolytic enzyme that is often utilized as a reference gene, and in this preliminary study, we evaluated the similarity of bobwhite GAPDH to GAPDH in other avian species to evaluate its potential as a reference gene in bobwhite. GAPDH was identified in the bobwhite full genome sequence and multiple sets of PCR primers were designed to generate overlapping PCR products. These products were then sequenced and then aligned to generate the sequence for the full-length open reading frame (ORF) of bobwhite GAPDH. Utilizing this sequence, phylogenetic analyses and comparative analysis of the exon-intron pattern were conducted that revealed high similarity of GAPDH encoding sequences among bobwhite and other Galliformes. Additionally, This ORF sequence was also used to predict the encoded protein and its three-dimensional structure which like the phylogenetic analyses reveal that bobwhite GAPDH is similar to GAPDH in other Galliformes. Finally, GAPDH qPCR primers were designed, standardized, and tested with bobwhite both uninfected and infected with O. petrowi, and this preliminary test showed no statistical difference in expression of GAPDH between the two groups. These analyses are the first to investigate GAPDH in bobwhite. These efforts in phylogeny, sequence analysis, and protein structure suggest that there is > 97% conservation of GADPH among Galliformes. Furthermore, the results of these in silico tests and the preliminary qPCR indicate that GAPDH is a prospective candidate for use in gene expression analyses in bobwhite.

- Abstract
The potential of parasites to affect host abundance has been a topic of heated contention within the scientific community for some time, with many maintaining that issues such as habitat loss are more important in regulating wildlife populations than diseases. This is in part due to the difficulty in detecting and quantifying the consequences of disease, such as parasitic infection, within wild systems. An example of this is found in the Northern bobwhite quail ( Colinus virginanus ), an iconic game bird that is one of the most extensively studied vertebrates on the planet. Yet, despite countless volumes dedicated to the study and management of this bird, bobwhite continue to disappear from fields, forest margins, and grasslands across the United States in what some have referred to as "our greatest wildlife tragedy". Here, we will discuss the history of disease and wildlife conservation, some of the challenges wildlife disease studies face in the ever-changing world, and how a "weight of evidence" approach has been invaluable to evaluating the impact of parasites on bobwhite in the Rolling Plains of Texas. Through this, we highlight the potential of using "weight of the evidence" to better understand the complex effects of diseases on wildlife and urge a greater consideration of the importance of disease in wildlife conservation., Competing Interests: The authors declare no conflict of interest., (© 2020 The Authors.)

- Abstract
Background: The monarch butterfly (Danaus plexippus) is a conspicuous insect that has experienced a drastic population decline over the past two decades. While there are several factors contributing to dwindling monarch populations, habitat loss is considered the most significant threat to monarchs. In the United States, loss of milkweed, particularly in the Midwest, has greatly reduced the available breeding habitat of monarchs. This has led to extensive efforts to conserve and restore milkweed resources throughout the Midwest. Recently, these research and conservation efforts have been expanded to include other important areas along the monarch's migratory path., Results: During the fall of 2018, we conducted surveys of monarch eggs and larvae through West Texas. We documented monarch and queen butterfly (Danaus gilippus) reproduction throughout the region and used the proportion of monarch and queen larva to estimate the number of monarch eggs. Peak egg densities for monarchs were as high as 0.78 per milkweed ramet after correction for the presence of queens. Despite our observations encompassing only a limited sample across one season, the peak monarch egg densities we observed exceeded published reports from when monarch populations were higher., Conclusions: To our knowledge, this is the first study to correct for the presence of queens when calculating the density of monarch eggs. This research also provides insight into monarch utilization of less well-known regions, such as West Texas, and highlights the need to expand the scope of monarch monitoring and conservation initiatives. While the importance of monarch research and conservation in the Midwest is unquestionable, more comprehensive efforts may identify new priorities in monarch conservation and lead to a more robust and effective overall strategy, particularly given the dynamic and rapidly changing global environment.

- Abstract
Background: Oxyspirura petrowi (Spirurida: Thelaziidae), a heteroxenous nematode of birds across the USA, may play a role in the decline of the northern bobwhite (Colinus virginianus) in the Rolling Plains Ecoregion of West Texas. Previous molecular studies suggest that crickets, grasshoppers and cockroaches serve as potential intermediate hosts of O. petrowi, although a complete study on the life-cycle of this nematode has not been conducted thus far. Consequently, this study aims to improve our understanding of the O. petrowi life-cycle by experimentally infecting house crickets (Acheta domesticus) with O. petrowi eggs, feeding infected crickets to bobwhite and assessing the life-cycle of this nematode in both the definitive and intermediate hosts., Methods: Oxyspirura petrowi eggs were collected from gravid worms recovered from wild bobwhite and fed to house crickets. The development of O. petrowi within crickets was monitored by dissection of crickets at specified intervals. When infective larvae were found inside crickets, parasite-free pen-raised bobwhite were fed four infected crickets each. The maturation of O. petrowi in bobwhite was monitored through fecal floats and bobwhite necropsies at specified intervals., Results: In this study, we were able to infect both crickets (n = 45) and bobwhite (n = 25) with O. petrowi at a rate of 96%. We successfully replicated and monitored the complete O. petrowi life-cycle in vivo, recovering embryonated O. petrowi eggs from the feces of bobwhite 51 days after consumption of infected crickets. All life-cycle stages of O. petrowi were confirmed in both the house cricket and the bobwhite using morphological and molecular techniques., Conclusions: This study provides a better understanding of the infection mechanism and life-cycle of O. petrowi by tracking the developmental progress within both the intermediate and definitive host. To our knowledge, this study is the first to fully monitor the complete life-cycle of O. petrowi and may allow for better estimates into the potential for future epizootics of O. petrowi in bobwhite. Finally, this study provides a model for experimental infection that may be used in research examining the effects of O. petrowi infection in bobwhite.

- Abstract
Helminth parasites have been a popular research topic due to their global prevalence and adverse effects on livestock and game species. The Northern bobwhite (Colinus virginianus), a popular game bird in the USA, is one species subject to helminth infection and has been experiencing a decline of > 4% annually over recent decades. In the Rolling Plains Ecoregion of Texas, the eyeworm (Oxyspirura petrowi) and caecal worm (Aulonocephalus pennula) helminths are found to be highly prevalent in bobwhite. While there have been increasing studies on the prevalence, pathology, and phylogeny of the eyeworm and caecal worm, there is still a need to investigate the bobwhite immune response to infection. This study utilizes previously sequenced bobwhite cytokines and toll-like receptors to develop and optimize qPCR primers and measure gene expression in bobwhite intramuscularly challenged with eyeworm and caecal worm glycoproteins. For the challenge experiments, separate treatments of eyeworm and caecal worm glycoproteins were administered to bobwhite on day 1 and day 21. Measurements of primary and secondary immune responses were taken at day 7 and day 28, respectively. Using the successfully optimized qPCR primers for TLR7, IL1β, IL6, IFNα, IFNγ, IL10, and β-actin, the gene expression analysis from the challenge experiments revealed that there was a measurable immune reaction in bobwhite in response to the intramuscular challenge of eyeworm and caecal worm glycoproteins.

- Abstract
Per- and polyfluoroalkyl substances (PFAS) are a group of fluorinated substances that are in the focus of researchers and regulators due to widespread presence in the environment and biota, including humans, of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). Fluoropolymers, high molecular weight polymers, have unique properties that constitute a distinct class within the PFAS group. Fluoropolymers have thermal, chemical, photochemical, hydrolytic, oxidative, and biological stability. They have negligible residual monomer and oligomer content and low to no leachables. Fluoropolymers are practically insoluble in water and not subject to long-range transport. With a molecular weight well over 100 000 Da, fluoropolymers cannot cross the cell membrane. Fluoropolymers are not bioavailable or bioaccumulative, as evidenced by toxicology studies on polytetrafluoroethylene (PTFE): acute and subchronic systemic toxicity, irritation, sensitization, local toxicity on implantation, cytotoxicity, in vitro and in vivo genotoxicity, hemolysis, complement activation, and thrombogenicity. Clinical studies of patients receiving permanently implanted PTFE cardiovascular medical devices demonstrate no chronic toxicity or carcinogenicity and no reproductive, developmental, or endocrine toxicity. This paper brings together fluoropolymer toxicity data, human clinical data, and physical, chemical, thermal, and biological data for review and assessment to show that fluoropolymers satisfy widely accepted assessment criteria to be considered as "polymers of low concern" (PLC). This review concludes that fluoropolymers are distinctly different from other polymeric and nonpolymeric PFAS and should be separated from them for hazard assessment or regulatory purposes. Grouping fluoropolymers with all classes of PFAS for "read across" or structure-activity relationship assessment is not scientifically appropriate.

- Abstract
The outcome for patients attempting dietary therapy for epilepsy a second time is unknown. Twenty-six subjects treated with the ketogenic diet as children who then began either the ketogenic diet or a Modified Atkins Diet (MAD) at least 6 months later were evaluated. The mean age at the first diet trial was 5.6 years and at the second diet trial was 11.5 years. Most restarted dietary therapy because of persistent seizures (65%) or recurrence after seizure freedom (19%). Overall, 77% had a ≥50% seizure reduction with the first diet, and 50% with the second diet, P = .04. Individual subject responses were largely similar, with 14 (54%) having identical seizure reduction both times, 9 worse (35%) with the second attempt, and 3 (16%) improved. The second diet trial was more likely to lead to >50% seizure reduction if the first trial was started at a later age (7.4 vs 3.9 years, P = .04)., (© The Author(s) 2016.)

- Abstract
Objectives: Over 250 medical centers worldwide offer ketogenic diets to children with epilepsy; however, access to these therapies has been extremely limited for adults until recent years. We examine our 5-year experience creating and implementing a dedicated Adult Epilepsy Diet Center designed to provide adults with epilepsy access to ketogenic diets., Material and Methods: Outpatients seen at the Johns Hopkins Adult Epilepsy Diet Center from August 2010 thru September 2015 age 18years and older were enrolled in a prospective open-label observational study. Patients that also enrolled in ongoing clinical diet trials were excluded from this study. Participant demographics, diet type, urine and/or serum ketones, laboratory studies, seizure frequency, diet duration, reason for discontinuing diet therapy, and side effects were recorded. A subgroup analysis of participants that met International League Against Epilepsy (ILAE) criteria for drug-resistant epilepsy (DRE) and were treated de novo with a Modified Atkins Diet (MAD) was performed to compare outcomes with the current literature regarding efficacy of other antiseizure treatments for DRE., Results: Two hundred and twenty-nine adults attended the Adult Epilepsy Diet Center, and 168 met inclusion criteria. Two-thirds (n=113, 67%) were women with an age range of 18-86years at the initial visit. Thirty-five participants (21%, n=133) were already on a therapeutic diet while 79% (n=133) were naïve to diet therapy at the time of the initial visit. Diet-naïve participants were typically prescribed MAD (n=130, 98%), unless unable to intake adequate oral nutrition, in which case they were prescribed KD (n=1) or a combination of oral MAD and ketogenic formula (n=2). Twenty-nine of 130 (22%) participants prescribed MAD elected not to start or were lost to follow-up, and 101 (78%) began MAD. A subgroup analysis was performed on one hundred and six participants naïve to diet therapy that met International League Against Epilepsy criteria for DRE, were able to tolerate oral nutrition, and were prescribed a MAD. Relative to the number of enrolled participants who had reliable follow-up results for a given duration (including those that ultimately elected not to start or were later lost to follow-up), at 3months, 36% of these participants responded (≥50% seizure reduction) to diet therapy, and 16% were seizure-free. At 1year, 30% responded, and 13% were seizure-free. At 4years, 21% responded, and 7% were seizure-free. Hyperlipidemia was the most common side effect (occurring in 39% of screened participants, including those on a therapeutic diet prior to the initial visit). Weight loss was also common (occurring in 19% of all participants treated with a ketogenic diet therapy) yet was often an intended effect., Significance: This study, the largest series of adults with epilepsy treated with ketogenic diet therapies to date, provides evidence that ketogenic diets may be feasible, effective, and safe long-term in adults, although long-term adherence was limited and further adequately controlled studies are necessary to determine the efficacy of ketogenic diets in the treatment of adults with epilepsy., (Copyright © 2016 Elsevier Inc.

Strowd RE, Cervenka MC, Henry BJ, Kossoff EH, Hartman AL, and Blakeley JO
- Abstract
Dietary glycemic modulation through high-fat, low-carbohydrate diets, which induce a state of systemic ketosis and alter systemic metabolic signaling, have been incorporated into the clinical management of patients with neurological disease for more than a century. Mounting preclinical evidence supports the antitumor, proapoptotic, and antiangiogenic effects of disrupting glycolytic metabolism through dietary intervention. In recent years, interest in incorporating such novel therapeutic strategies in neuro-oncology has increased. To date, 3 published studies incorporating novel dietary therapies in oncology have been reported, including one phase I study in neuro-oncology, and have set the stage for further study in this field. In this article, we review the biochemical pathways, preclinical data, and early clinical translation of dietary interventions that modulate systemic glycolytic metabolism in the management of primary malignant brain tumors. We introduce the modified Atkins diet (MAD), a novel dietary alternative to the classic ketogenic diet, and discuss the critical issues facing future study.

- Abstract
Many studies have documented high prevalence of burnout and compassion fatigue in oncology nurses. Burnout has detrimental effects on nurses, patients, and healthcare organizations. However, burnout interventions have been shown to improve the physical and mental health of nurses, patient satisfaction, and the organizational bottom line by reducing associated costs of burnout. Although treatment centers may prevent and correct burnout in oncology nurses by providing various interventions, few articles focus on those interventions. This article compiles and describes interventions that will serve as a reference to nurses and healthcare organization leaders interested in implementing similar programs.

- Abstract
The modified Atkins diet has been used since 2003 for the treatment of children and adults with refractory epilepsy.This “alternative” ketogenic diet is started in clinic, without fasting, hospitalization, and restriction of protein,calories, or fluid intake. Now after 10 years of continued use, approximately 400 patients have been reported in over 30 studies of the modified Atkins diet as treatment for intractable seizures, with results demonstrating similar efficacy to the ketogenic diet and improved tolerability. The modified Atkins diet is being increasingly used in the adult population. Clinical trials have provided insight into the mechanisms of action of dietary therapies overall. This review will discuss the past decade of experience with the modified Atkins diet as well as predictions for its role in the treatment of epilepsy a decade from now.

- Abstract
Purpose: To examine the process for transitioning adolescents on dietary management for intractable epilepsy to adult neurologic care., Methods: Ten patients, ages 6-16 years when the ketogenic or modified Atkins diet was initiated, were identified; age at transition was 18-43 years. All patients were seen at Johns Hopkins Hospital, Baltimore, Maryland., Results: Seven remain on diets (4 Ketogenic, 3 modified Atkins diet) at this time with mean diet duration of 15.5 years (range 4-32 years). Most patients had excellent but not complete seizure control and several had recurrence or worsening of seizures with attempts to wean dietary therapy, hence the need to continue. Three main transition options were utilized: (1) continue being followed in pediatric clinic (n=2), (2) establish care with an adult neurologist (n=2), or 3) receive care from the Adult Epilepsy Diet Center (n=6). Those patients followed in the Adult Epilepsy Diet Center were slightly more likely to remain on dietary therapy following transition (5/6 vs. 1/4, p=0.12)., Conclusion: It is important for adolescents with epilepsy receiving ketogenic diets to have transition plans in place for when they become adults. Adult epilepsy diet centers are the ideal option when possible., (Copyright © 2013 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.)

- Abstract
Oncology nurses should be aware of smoking-related public health legislation and tobacco use prevention resources as well as increase their knowledge of psycho-education materials, medications, and products available to aid smoking cessation. Smoking is the leading cause of preventable death; one out of five deaths in the United States is attributed to smoking. Each day, almost 4,000 Americans younger than age 18 try their first cigarette, and 1,000 of those youths will become regular smokers. In 2009, House Resolution 1256: The Family Smoking Prevention and Tobacco Control Act gave the U.S. Food and Drug Administration the authority to regulate tobacco products with emphasis placed on prevention of the use by youth through graphic health warnings. Most states and many countries have enacted bans on smoking in all enclosed public places; however, some still allow smoking in adult-specific venues, such as bars, and some have not enacted any general statewide ban on smoking in any nongovernment-owned spaces. Oncology nurses can be instrumental in advocating for tobacco control legislation as well as providing and supporting services focused on smoking cessation and the prevention of tobacco use.

- Abstract
Juvenile myoclonic epilepsy (JME) is often successfully managed with anticonvulsants; however, some patients may have medically resistant seizures. The modified Atkins diet (MAD) has been reported as effective for idiopathic generalized epilepsy and is increasingly being used in adolescents and adults. Since 2006, 8 adolescents and adults have been started on the MAD for JME at Johns Hopkins Hospital. Of these 8 patients, 6 (75%) were female, with a mean age at seizure onset of 10.5 years (range: 6-13 years) and 24.3 years (range: 15-44 years) at MAD initiation. After 1 month, 6 (75%) patients had >50% seizure reduction, and after 3 months, 5 (63%) patients had >50% improvement. Several patients found the MAD difficult to adhere to, including 3 patients who reported temporarily increased seizures during periods of noncompliance. In this limited experience, the modified Atkins diet was an efficacious adjunctive therapy for young adults with very medically resistant JME., (Copyright © 2012 Elsevier Inc. All rights reserved.)

- Abstract
Purpose: The modified Atkins Diet (MAD) is an effective dietary treatment for children with epilepsy. However, adults may have limited access to this therapy because of lack of availability of dietitian or nutrition support or familiarity with the diet by their treating neurologist. This study was designed to investigate the tolerability and efficacy of the MAD administered solely via e-mail to adults with pharmacoresistant epilepsy., Methods: A prospective, open-label, proof-of-principle 3-month study design was employed. Adults were enrolled, instructed on how to self-administer a 20 g carbohydrate per day MAD, and followed by the investigators only via e-mail. There were no clinic visits or dietitian contacts during the study period., Key Findings: Twenty-five participants (median age 30 years [range 18-66 years], 68% female) consented and 22 started the MAD. The median prior anticonvulsants was 5 (range 2-10) and seizure frequency was 5 per week (range 1-140). Urinary ketosis was achieved in 21 participants (95%), of which 16 (76%) reported at least 40 mg/dl (moderate). Twenty-one participants (95%) remained on the MAD at 1 month and 14 (64%) at 3 months. After 1 month, 9 (41%) had >50% seizure reduction including one (5%) with >90% seizure reduction using intent-to-treat analysis. After 3 months, 6 (27%) had >50% seizure reduction including 3 (14%) with >90% seizure reduction. The mean ketogenic ratio was 1.1:1 (fat:carbohydrates and protein) for those who provided a MAD food record at follow-up. Over the study period, the median number of e-mails sent by the participants was 6 (range 1-19). The most frequent side effect was weight loss., Significance: E-mail administration of the MAD to adults with refractory epilepsy appears to be feasible and effective. Therefore, when dietitian or physician support is limited for adult patients with epilepsy, remote access via telemedicine could provide an alternative., (Wiley Periodicals, Inc. © 2012 International League Against Epilepsy.)

- Abstract
Genetically modified (GM) rice (LibertyLink, event LLRICE62) that is tolerant to glufosinate ammonium (Liberty) herbicide was compared with a near-isogenic (NI) conventional medium-grain brown rice (cultivar, Bengal) and a commercially milled long-grain brown rice in diets for growing-finishing pigs. The GM and NI rice were grown in 2000. The GM rice was from fields treated (GM+) or not treated (GM-) with glufosinate herbicide. The GM- and NI rice were grown using herbicide regimens typical of southern United States rice production practices. The four rice grains were similar in composition. Growing-finishing pigs (n = 96) were fed fortified rice-soybean meal diets containing the four different rice grains from 25 to 106 kg BW. Diets contained 0.99% lysine initially (growing phase), with lysine decreased to 0.80% (early finishing phase) and 0.65% (late finishing phase), when pigs reached 51 and 77 kg, respectively. The percentage of rice in the four diets was constant during each of the three phases (72.8, 80.0, and 85.8% for the growing, early-finishing, and late-finishing phases, respectively). There were six pen replicates (three pens of barrows and three pens of gilts) and four pigs per pen for each dietary treatment. All pigs were slaughtered at the termination of the study to collect carcass data. At the end of the 98-d experiment, BW gain, feed intake (as-fed basis), and feed:gain ratio did not differ (P > 0.05) for pigs fed the GM+ vs. conventional rice diets, but growth performance traits of pigs fed the GM+ rice diets were superior (P < 0.05) to those of pigs fed the GM- rice diet (ADG = 0.86, 0.79, 0.81, and 0.85 kg/d; ADFI = 2.41, 2.49, 2.37, and 2.45 kg/d; feed:gain = 2.80, 3.17, 2.95, and 2.89 for GM+, GM-, NI, and commercially milled rice, respectively). Carcass traits (adjusted for final BW) did not differ (P = 0.10) among treatments (hot carcass yield = 73.5, 72.6, 72.6, and 73.2%; 10th-rib backfat = 23.0, 22.7, 21.3, and 23.8 mm; LM area = 38.6, 38.0, 38.2, and 38.1 cm(2); carcass fat-free lean = 50.5, 50.5, 51.2, and 50.0%). Gilts grew slower (P < 0.05) and were leaner (P < 0.05) than barrows. Responses to type of rice did not differ between barrows and gilts, with no evidence of a diet x gender interaction (P = 0.50) for any trait. The results indicate that the glufosinate herbicide-tolerant rice was similar in composition and nutritional value to conventional rice for growing-finishing pigs.

- Abstract
To test the effects of lidocaine and bupivacaine on early fracture healing, the tensile strength of five groups of femora from normal rats 14 and 35 days after production of a closed diaphyseal fracture were compared. Data indicate that, in experimental animals injected with local anesthetics at the fracture site, no measurable difference is noted in callus composition, tensile strength, or histological appearance during the early phases of fracture repair prior to callus remodeling.

- Abstract
The Thomas splint has been used since the late 1800s. During World War I, physicians began using it for the acute management of femoral fractures and attributed its use to reduced mortality associated with these injuries. However, articles differ as to the actual percentage of mortality reduction. Even though these discrepancies exist, the Thomas splint has been useful and is still used today, especially for patient transport while awaiting definitive management.

- Abstract
The Safety and Health Index System (SHIS) has developed beyond its initial role as an in-plant labeling system. It has evolved into a classification scheme to rank the hazards found in the workplace and is useful in prioritizing industrial hygiene monitoring programs, installation of engineering controls, and implementation of medical monitoring for chronic hazards. In addition to providing objective criteria on which to evaluate physical and acute health hazards, this system addresses chronic health hazards such as carcinogens, mutagens, teratogens, and reproductive toxins.
