Background For the fixation of displaced midshaft clavicular fractures different plates are available, each with its specific pros and cons. The ideal plating choice for this lesion remains subject to ongoing discussion. Reconstruction plates are cheap and easily bendable, but their strength and stability have been questioned. The aim of this study was to evaluate the failure rate of reconstruction plates in the fixation of clavicular fractures. Materials and methods A multicenter, retrospective cohort study of all consecutive patients with a displaced, midshaft clavicular fracture (Robinson type 2a/2b) treated with a 3.5-mm reconstruction plate between 2006 and 2013 were evaluated. The primary outcome measure was reoperation rate due to implant failure. Secondary outcome measures were nonunion, symptomatic malunion and elective plate removal. Results One hundred and eleven patients were analyzed. During a median follow-up of 8 months, 14 patients (12.6%) had implant failure, of which 7 (6.3%) required a reoperation. Three nonunions (2.7%) and no symptomatic malunions occurred. Plate removal was indicated in 37.8% of patients because of implant irritation. Discussion The incidence of reoperation due to implant failure following clavicular plate fixation with a reconstruction plate is 6.3%. Although comparison with other plate types is difficult since rates in literature vary greatly, reoperation rates in other plates are reported around 2–3%, suggesting that reconstruction plates have a higher incidence of implant failure warranting reoperation. Therefore, especially in patients with known risk factors for complications (e.g. smoking, osteoporosis, comminuted fractures), a stronger plate than a reconstruction plate should be considered.

BackgroundPostoperative ileus is a common complication of abdominal surgery, leading to patient discomfort, morbidity and prolonged postoperative length of hospital stay (LOS). Previous studies suggested that chewing gum stimulates bowel function after abdominal surgery, but were underpowered to evaluate its effect on LOS and did not include enhanced recovery after surgery (ERAS)-based perioperative care. This study evaluated whether chewing gum after elective abdominal surgery reduces LOS and time to bowel recovery in the setting of ERAS-based perioperative care.MethodsA multicentre RCT was performed of patients over 18 years of age undergoing abdominal surgery in 12 hospitals. Standard postoperative care (control group) was compared with chewing gum three times a day for 30 min in addition to standard postoperative care. Randomization was computer-generated; allocation was concealed. The primary outcome was postoperative LOS. Secondary outcomes were time to bowel recovery and 30-day complications.ResultsBetween 2011 to 2015, 1000 patients were assigned to chewing gum and 1000 to the control arm. Median LOS did not differ: 7 days in both arms (P = 0·364). Neither was any difference found in time to flatus (24 h in control group versus 23 h with chewing gum; P = 0·873) or time to defaecation (60 versus 52 h respectively; P = 0·562). The rate of 30-day complications was not significantly different either.ConclusionThe addition of chewing gum to an ERAS postoperative care pathway after elective abdominal surgery does not reduce the LOS, time to bowel recovery or the rate of postoperative complications. Registration number: NTR2594 (Netherlands Trial Register).

INTRODUCTION: The widely used antiepileptic drug (AED) Levetiracetam has previously been associated with behavioural changes. We hypothesised that patients taking Levetiracetam would experience higher levels of fatigue than patients on other AEDs. METHOD: Secondary analysis of a prospective observational study. Clinically stable adult outpatients with cerebral glioma completed a Visual Analogue Scale for fatigue (range 0-100mm, called ‘high' if >60mm). AED prescription was prospectively recorded. RESULTS: N = 166 patients consented to participate in the parent study (61% male; mean age 49yrs; 70% high-grade glioma). Fatigue was commonly reported (high in 43%; 95%CI 35-50%). AEDs were prescribed singly or multiply to most patients (n = 113). Levetiracetam (LEV) was the most frequent AED monotherapy. With clinical and statistical significance, patients on LEV monotherapy reported higher fatigue (n = 33, mean = 57mm, SD 5.2, 95%CI 46-67mm) than those on monotherapy with any other AED (n = 50, mean = 43mm, SD 3.9, 95%CI 35-50mm, t-test p < 0.0001). Surprisingly, this association was independent of functional status (ANCOVA p = 0.04, LR p < 0.0001, R2 = 27.7). Patients on LEV were more than twice as likely to report high fatigue as patients on other AEDs (OR 2.7 [1.1-6.2]). We observed similar findings with polytherapy involving LEV. CONCLUSION: Therapy-related side effects reduce quality of life and treatment compliance while increasing healthcare costs. Our data suggest that fatigue may be more common with Levetiracetam therapy specifically. Specialist review of AED medication may benefit some glioma patients with severe or persistent fatigue. Explanatory biological mechanisms of LEV-specific fatigue could be experimentally pursued.

Glass melts in the system Fe 2 O 3 /FeO/CaO/Na 2 O/B 2 O 3 were prepared from the raw materials, by firstly reducing them by flushing with nitrogen and subsequently roller quenching. The flakes obtained had a thickness of around 150 μm and were thermally treated at temperatures in the range from 550 to 620 °C. X-ray diffraction gave evidence of the occurrence of nanocrystalline magnetite. Magnetization measurements at room temperature show ferromagnetic behaviour and no hysteresis. Temperature-dependent measurements showed a monotonic decrease of the saturation magnetization with temperature, and a Curie temperature of 553 °C. The primary mean particle core diameter is around 10 nm after annealing at 570 °C.

Populations of copper-resistant (Cu r ) strains of Xanthomonas campestris pv. vesicatoria were monitored in the field on nonsymptomatic tomato leaflets treated with copper or with a copper and mancozeb mixture over three and four seasons, respectively. Copper and a combination of copper and mancozeb reduced epiphytic populations of X. c. vesicatoria, compared to those in the untreated control. Populations of X. c. vesicatoria on leaflets receiving copper and the copper-mancozeb combination differed significantly in only one of three seasons. A positive correlation was observed between epiphytic populations and disease severity (...)

Horticulture - Abstract
Foliar-bract calcium (Ca) sprays and fertilization practices that altered Ca availability and supply were evaluated for their effect on marginal bract necrosis incidences of ‘Gutbier V-14 Glory’ poinsettia (Euphorbia pulcherrima Willd.). About 90% fewer marginal necrotic lesions were observed on plants receiving an 81% NO3-N and 903-ppm Ca soluble fertilizer with 10% of the total nutrients foliar-applied than on plants grown with medium-applied Osmocote 19N-2.6P-10K (47% NO3-N) or with medium-applied liquid fertilizer containing 30% or 65% NO3-N and 0 ppm Ca. Addition of 354 ppm Ca in a 53% NO3-N, or 964 ppm Ca in a 75% NO3-N medium-applied fertilizer did not significantly reduce the number of lesions compared to the same fertilizer with 0 ppm Ca or the equivalent rate of a 53% NO3-N Osmocote 14N-6.1P-11.6K. Weekly foliar-bract sprays of 432 ppm Ca from Ca(NO3)2·4H2O reduced numbers of lesions by 94% (

Genetics ,Horticulture - Abstract
Plants of ‘Croft’, ‘Ace’ and ‘Nellie White’ grown in F- or Li-amended sand cultures had injured leaves. F-injury on ‘Croft’ developed as a semi-circular necrotic area at the margin of the leaf near its apex. The necrosis enlarged until the entire leaf tip and margin became necrotic. F injury on ‘Ace’ and ‘Nellie White’ varied from the semi-circular necrosis pattern to chlorotic or necrotic leaf margins. Injury affected only lower leaves of ‘Ace’ and ‘Nellie White’ but affected all leaves of ‘Croft’. Li injured leaves of all cultivars but the number and degree of injury were less than those produced by F. Li injury developed as chlorotic leaf margins which eventually became necrotic. In all cultivars Li injury was confined to lower leaves. ‘Croft’ was more sensitive to F and Li than ‘Ace’ or ‘Nellie White’. ‘Ace’ and ‘Nellie White’ were also grown in soil amended with dicalcium phosphate or superphosphate at both low and high lime rates and fertilized with NH4-N or NO3-N nitrogen. Plants grown with dicalcium phosphate with NH4-N or at any lime rate had no leaf injury. Plants grown with superphosphate had injured leaves, particularly at low lime rates with NH4-N. Soil and plant analysis showed a high positive correlation between superphosphate, which contains F, and leaf scorch. Soil-borne F was influenced by source of N fertilizer and lime rate. The pattern of leaf scorch from superphosphate in ‘Nellie White’ and ‘Ace’ was the same as that from NaF.

An apparent physiological disease, Yellow Strapleaf (YSL) of Chrysanthemnum morifolium Ram., was described by Jackson and Woltz (1) in 1959. The disease has been observed in Florida plantings during the last 6 years and has been noted in Massachusetts 3. Symptoms include chlorosis of new growth, green netting of leaves, and narrow strapshaped leaves that hook at the distal ends (fig 1A). The condition may persist for 2 to 8 weeks causing mild to severe stunting of plants and has been found in 20 commercial chrysanthemum varieties. YSL has not been corrected by the application of inorganic nutrient elements or linked directly with any fungal, bacterial, or viral pathogen. Chemical analyses of plant and soil have not indicated any significant differences in content of inorganic nutrients. Higher soil pH was usually associated with the disorder. Woltz and Jackson (6) presented results of experiments that linked frenching of tobacco (Nicotiana tabacum L.) and YSI, of chrysanthemum as being apparently caused by similar soil conditions and resulting in similar syndromes. Both disorders are favored by relatively high soil pH, periods of high soil moisture levels, and high soil temperatures. The symptoms displayed with the diseases (1, 5) have three common features: A: green netting or reticular chlorosis of leaves, B: narrow, strap-shaped leaves, and C: growth retardation. Tobacco and chrysanthemum plants growing together in containers of soil that had produced YSL in the field developed symptoms of the respective diseases of frenching and YSL. Following the information set forth by Steinberg (5) that isoleucine and certain other amino acids were effective in producing frenching, DL-isoleucine with DL-alloisoleucine was applied to the root zone of chrysanthemum plants. This amino acid treatment uniformly and quickly produced YSL symptoms with plants growing in solution culture, steamed soil, methyl bromide-treated soil, untreated soil, quartz sand and expanded volcanic glass (perlite). Six chrysanthemum varieties of varying degrees of susceptibility to YSL were treated with isoleucine in this experiment. YSL symptoms developed in all varieties with severity approximately in the order of observed field susceptibility. This report presents data on the effects of certain specific amino acids on the growth of chrysanthe

The question of the significance of free amino acids in soil or other cultural media has received attention in recent years in the fields of plant physiology (1, 3, 7, 13, 14, 15, 16, 17), soil microbiology (4, 5,11, 16) and soil chemistry (9, 10,12). Although it originally appeared that free amino acids were not to be found in soils, later reports (2, 10) indicated they could be extracted with aqueous and alcoholic solutions and determinations made with chromatographic methods. The quantities of amino acids found were quite variable. Amino acids added to soil were quite rapidly transformed, and usually undetectable in extracts made after 72 to 96 hours of incubation (11, 16). D-Amino acids and L-alloisoleucine appeared more resistant to change than other amino acids studied (16). Reports indicate that amino acids are absorbed by plants (3, 13, 14) and translocated with great speed in both phloem and xylem (8). Inhibitors of respiratory processes as well as low temperatures applied to fibrovascular tissue considerably retard translocation. The potential applications of research with the so-called unnatural (D-) isomers was pointed out (6, 17) in connection with the natural occurrences of Damino acids in antibiotics and parts of microorganisms. More recently, Ikawa, et al. (6) reported the finding of D-phenylalanine, D-allothreonine and D-alloisoleucine3 in peptido-lipids of bacterial origin. The demonstrated effectiveness of amino acids applied to root zones of plants in producing changes in morphology and growth rate (1, 13, 17) suggests a need for further research along these lines. Steinberg (13) found that frenching of tobacco could be simulated by furnishing leucine, isoleucine, or alloisoleucine to tobacco plants growing in sterile cultures. He reported that relatively large amounts of these amino acids were required under non-sterile conditions to produce frenching symptoms. Woltz and Jackson (15, 16, 17) found that symptoms of yellow strapleaf of chrysanthemum could be produced by small amounts of certain isomers of leucine, isoleucine, and alloisoleucine applied to the root zones of test plants growing in sterilized and nonsterilized media. Fifteen of twenty-two test plants developed syndromes similar to those of frenching and yellow strapleaf when a mixture of alloisoleucine and isoleucine isomers was applied to the root zones. Methionine applied to the root zones of chrysanthemum plants produced a physi-ological disorder given the name methionosis (17). Two of the twenty-two plants exhibited morphological changes due to methionine. A consideration of the information about the effects of externally applied amino acids on plant growth in the light of certain antimetabolite phenomena discussed by Woolley (18) led to the hypothesis that the growth-modifying effects observed might be largely antimetabolite effects. Natural (L-) amino acids could act as antimetabolites because of their structural similarity to other natural amino acids. Unnatural amino acids (D-form & others), due to their structural similarity to specific natural amino acids, could function as antimetabolites by being incorporated into peptides and blocking further synthesis due to the failure to completely fit the pattern of the natural amino acid. Experiments were planned to examine further the effects of various natural and synthetic amino acids on the growth rate and morphology of chrysanthemum plants. Chrysanthemum was selected for these studies because of its sensitivity to isomers of leucine, isoleucine, and methionine (17). The types of cultural media, amounts of amino acids applied, and timing of application relative to the development of new growth of axillary shoots were chosen to enhance growth effects so the effects might be recorded and evaluated. Interactions of related amino acids were explored to learn the degree to which the results would fit metabolite-antimetabolite relationships.

T. K. Howe and S. S. Woltz
- Subjects
Horticulture - Abstract
Thirty-nine cultivars of marigold (Tagetes spp.) were exposed to sulfur dioxide to determine their relative sensitivity. Flowering plants were fumigated at 1 ppm SO2 for 4 hours or at 2 ppm SO2 for 2 hours. The average foliar injury for all leaves on individual plants ranged from 42.3% for ‘Crackerjack Mix’ at 2 ppm SO2 to 0.0% for ‘Cupid Yellow’ at 1 ppm SO2. Foliar necrosis appeared as a gray to white marginal and/or interveinal scorch 1 day after exposure. There was a tendency for interveinal necrosis to be near the midvein. The extra-floral nectaries which line the leaf margins of marigold were scorched in 15 of the 39 cultivars. This injury may be of diagnostic value. Sepals were very sensitive to SO2. Sepal injury appeared as a pinpoint scorch and as tip burn, and was apparent in some cultivars when no foliar injury occurred.

Horticulture - Abstract
Comparative fumigation procedures were used to evaluate the relative susceptibility of some ornamental plant species to the toxic effects of airborne fluoride in compartmentalized greenhouse chambers. Susceptibility classification was based on the speed of development of toxicity symptoms together with the specific concentrations of hydrofluoric acid vapor causing fluorosis. Symptoms of fluoride toxic effects were recorded for use in diagnosis and evaluation of damage.

Copper-sensitive and -resistant strains of Xanthomonas campestris pv. vesicatoria (XCV) were grown in specially purified nutrient solutions to study the interaction of Cu (0.0, 0.317, 1.0, 3.17, and 10 μg/ml) and Mg (0.25, 2.5, and 25 μg/ml) on the in vitro growth of XCV. The Cu-sensitive strain was inhibited considerably more than the resistant strain at 1.0, 3.17, and 10 μg/ml Cu levels. Bacterial growth of the Cu-sensitive strain at the highest Cu level was inhibited completely at all Mg levels. The Cu-resistant XCV, when exposed to the highest Cu concentration, was capable of significant growth at all Mg levels. An interaction between Cu and Mg was found with the resistant XCV at 3.17 and 10.0 μg/ml Cu whereby the Cu inhibition of growth of the XCV was much reduced by the high Mg level (25 μg/ml) in comparison with the intermediate Mg level (0.25 μg/ml). Mg, when applied as a foliar spray, may reduce the efficacy of copper sprays.

Fusarium wilt (Fusarium oxysporum Schlecht. f. sp. lycopersici (Sacc.) Snyder and Hansen) of tomato (Lycopersicon esculentum Mill.) was first reported in the United States in 1899 by E.F. Smith who said that the disease had put an end to the growing of tomatoes for the northern markets in certain areas of Florida. By 1920, the disease had become widespread and destructive throughout the southeast, midwest, and middle Atlantic states (Walker 1971).

Horticulture - Abstract
A hypothesis was tested that the cause of a damaging marginal bract necrosis common to ‘Gutbier V-14 Glory’ poinsettia is a deficiency of Ca that is expressed when the rapidly growing bract outdistances the current supply of Ca. Plants were grown in the greenhouse in a sedge peat-EauGallie sand mix with fertility adjustments designed to moderately enhance Ca deficiency. Twice-weekly foliar applications of Ca (432 ppm) were begun at the stage of first bract coloration to attempt to prevent necrosis. In addition to bract necrosis, puckering of bracts occurred on controls but not in Ca-treated plants. In another experiment, induced Ca deficiency symptomology included bract necrosis. Calcium chloride spray essentially prevented the necrosis. Necrotic bract marginal tissue had 0.07% Ca, whereas sprayed tissue contained more than three times this Ca concentration.

Tomato leaves soaked in solutions of 7 antimetabolite compounds were offered to larvae of Spodoptera eridania (Cramer) to determine whether these materials affect larval feeding and development. Thiouracil-treated leaves were not appreciably consumed by larvae, weight gain was poor, and only 1 adult was produced from 54 larvae fed this diet. Thiouracil apparently acts as a deterrent to larval feeding.

Symptoms of fusarium wilt of tomato were less severe in plants supplied with nitrate-N and greater in those supplied with ammonium-N. Liming with calcium hydroxide decreased disease severity but this effect was negated by high ammonium-low nitrate fertilization. The combination of high nitrate, low ammonium, and lime reduced disease development additively. Fusarium oxysporum f. sp. lycopersici race 2 was more virulent when grown in liquid culture with ammonium than with nitrate as the sole N source.

Simple Summary: Bathycoelia distincta poses a significant threat to the South African macadamia industry. Despite the acknowledged influence of temperature on insects, a comprehensive developmental biology investigation for B. distincta has not been undertaken to date. This study systematically presents empirical data on the effects of temperature on the developmental duration, survival, and developmental thresholds of B. distincta's life stages under constant temperatures. The findings of this study reveal that the thermal developmental range of this pest ranges from 13.5 to 38.0 °C, with an optimum temperature of 29.5 °C. Moreover, B. distincta requires 783 degree days to develop from an egg to the adult stage. Considering the prevailing global warming trends, the South African Macadamia industry may experience more damage due to a faster development at warmer temperatures. Temperature is the most influential condition affecting insect development and population dynamics. Understanding its impact and other important factors, such as diet, could provide fine-scale predictions of species abundance and distribution in space and time. The two-spotted stink bug, Bathycoelia distincta Distant (Hemiptera: Pentatomidae), is a significant pest of macadamia in South Africa for which limited information on developmental biology exists. Here, for the first time, variations in key developmental parameters of the B. distincta biology were studied systematically. The developmental duration, survival rate, development rate, lower developmental threshold (T
min ), optimum developmental threshold (Topt ), upper developmental threshold (Tmax ), and thermal constant were quantified for each developmental stage of B. distincta. In addition, the effect of diet (macadamia nut and sweetcorn) on the developmental duration and survival rate were quantified. This study was conducted at five constant temperatures (18, 21, 22, 25, and 29 °C) with relative humidity (RH) variations. The developmental duration from egg to adult decreased significantly with increased temperature: 21 °C (±60 days) to 29 °C (±32 days). The survival rate was significantly different for instar 2 between temperatures. Nymphs (instars 2 and 4) developed faster on the sweetcorn diet than on a macadamia diet, but the total developmental time did not differ significantly between the diets. Development from egg to adult required 783 degree days (DD), with a Tmin of 13.5 °C, Topt of 29.5 °C, and Tmax of 38 °C. Ongoing global warming will increase the population growth of B. distincta through increased development rate, resulting in more damage to macadamia nuts. Understanding the developmental biology and thresholds for the DD model of B. distincta is fundamental for predicting its phenology and outbreaks in macadamia orchards.

Influenza virus has been one of the most prevalent and researched viruses globally. Consequently, there is ample information available about influenza virus lifecycle and pathogenesis. However, there is plenty yet to be known about the determinants of influenza virus pathogenesis and disease severity. Influenza virus exploits host factors to promote each step of its lifecycle. In turn, the host deploys antiviral or restriction factors that inhibit or restrict the influenza virus lifecycle at each of those steps. Two broad categories of host restriction factors can exist in virus-infected cells: (1) encoded by the interferon-stimulated genes (ISGs) and (2) encoded by the constitutively expressed genes that are not stimulated by interferons (non-ISGs). There are hundreds of ISGs known, and many, e.g., Mx, IFITMs, and TRIMs, have been characterized to restrict influenza virus infection at different stages of its lifecycle by (1) blocking viral entry or progeny release, (2) sequestering or degrading viral components and interfering with viral synthesis and assembly, or (3) bolstering host innate defenses. Also, many non-ISGs, e.g., cyclophilins, ncRNAs, and HDACs, have been identified and characterized to restrict influenza virus infection at different lifecycle stages by similar mechanisms. This review provides an overview of those ISGs and non-ISGs and how the influenza virus escapes the restriction imposed by them and aims to improve our understanding of the host restriction mechanisms of the influenza virus.

Temperature and humidity are considered the main abiotic factors that affect both the development and survival of ectothermic organisms. In this study, we estimated the development time as well as the thermal requirements of the sugarcane borer, Diatraea saccharalis (Fabricius, 1794; Lepidoptera: Crambidae), a key insect pest of sugarcane and discussed the influence of temperature and relative humidity and its infestation intensity in a scenario of climate change.The models Brière-1 and Ikemoto-Takai provided the best fit to the data of development rate versus temperature.The average life cycle (from egg to adult) ranged from 39.21 ± 4.84 at 32 °C to 137.10 ± 7.47 at 18 °C days.The thermal constant and average base temperature were 547.69 degree-days and 13.64 °C, respectively.The number of larval instars varied from 4 to 7 depending on the temperature, being higher at lower temperatures.The thermal range comprised the interval from 16.7 °C to 33.9 °C and the optimum temperature was estimated as 27.4 °C. Locations with elevated temperature (≥25 °C) and high relative humidity (≥70%) presented larger populations of D. saccharalis. Our findings show that the infestation pressure of this species is highly influenced by both temperature and humidity, and the studied models allow to forecast pest outbreaks. In the context of climate change, information about the thermal range and the optimum temperature contributes to predicting the spatial-temporal distribution of D. saccharalis and, consequently, aids decision making in pest management. Graphical Abstract Resumo: Temperatura e umidade são consideradas os principais fatores abióticos que afetam o desenvolvimento e a sobrevivência de organismos ectotérmicos. Neste estudo, nós estimamos o tempo de desenvolvimento, bem como os requerimentos térmicos da broca da cana-de-açúcar, Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae), uma praga-chave da cana-de-açúcar e discutimos a influência da temperatura e umidade relativa e sua intensidade de infestação em um cenário de mudanças climáticas. Os modelos Brière-1 e Ikemoto-Takai forneceram o melhor ajuste aos dados de taxa de desenvolvimento versus temperatura. O ciclo de vida médio (do ovo ao adulto) variou de 39,21 ± 4,84 a 32 °C até 137,10 ± 7,47 dias a 18 °C. A constante térmica e a temperatura base média foram 547,69 graus-dia e 13,64 °C, respectivamente. O número de instares larvais variou de 4 a 7 dependendo da temperatura, sendo maior em temperaturas baixas. A faixa térmica compreendeu o intervalo de 16,7 °C a 33,9 °C e a temperatura ótima foi estimada em 27,4 °C. Locais com temperatura elevada (≥25 °C) e alta umidade relativa (≥70%) têm populações maiores de D. saccharalis. Nossos resultados mostram que a pressão de infestação desta espécie é altamente influenciada pela temperatura e umidade e os modelos estudados permitem prever surtos da praga. No contexto das mudanças climáticas, informação sobre a amplitude térmica e a temperatura ótima contribui para prever a distribuição espaçotemporal de D. saccharalis e, consequentemente, auxilia na tomada de decisão no manejo de pragas.

Background: Central venous catheters (CVCs) support the administration of chemotherapy and other medications, blood products, fluids, and nutrient infusions, and reduce the need for peripheral blood sampling in children with cancer. CVC use is also associated with the risk of central-line-associated bloodstream infection (CLABSI). Despite the implementation of CLABSI care bundles, CLABSI prevention remains challenging. Method: This project implemented supportive preventive care interventions to decrease CLABSI in pediatric hematology/oncology patients in a tertiary hospital in the Middle East region. Interventions included bathing or skin care once daily, oral care twice daily, and ambulating patients three times daily. Parent and staff education materials were developed. The project moniker was Step 1-2-3, inspired by successful implementations of such measures in a U.S. cohort showing reduced CLABSI rates. The project used a mixed methods approach. We report outcomes through August 2022. Results: Pre-project (12/2019–05/2020) five CLABSIs occurred in the inpatient unit. Following the implementation of Step 1-2-3, Pediatric Oncology achieved 492 CLABSI-free days. Six CLABSIs then occurred over a short period of time between October 2021 and January 2022, which was associated with high levels of patient acuity and staff sick leave. The inpatient ward remained CLABSI-free from January 9, 2022, through August 2022. Discussion: Extended periods of CLABSI-free care in a pediatric hematology/oncology unit are achievable. A variety of factors contribute to the sustainability of being CLABSI-free. Data collection and analysis are important factors which aided in our understanding of our own CLABSI events.

DROSOPHILA suzukii ,CLIMATE change ,WINTER ,INSECT pests ,COLD (Temperature) ,COLD regions - Abstract
Simple Summary: Drosophila suzukii, also known as the spotted-wing drosophila (SWD), is a polyphagous insect pest of soft-skinned small fruits. SWD, similar to other insects, is affected by climate change-associated factors, yet its impacts on the pest regarding its behavior, distribution, and survival remains poorly understood. Current climate change is allowing this species to colonize colder regions. This review explores how SWD adapts to survive during cold seasons, focusing on a plethora of overwintering strategies, and the transcriptomics changes in response to cold. Finally, it is discussed how climate change progression may promote the ability of this species to survive and spread, and what mitigation measures could be employed to overcome cold-adapted D. suzukii. Anthropogenic challenges, particularly climate change-associated factors, are strongly impacting the behavior, distribution, and survival of insects. Yet how these changes affect pests such as Drosophila suzukii, a cosmopolitan pest of soft-skinned small fruits, remains poorly understood. This polyphagous pest is chill-susceptible, with cold temperatures causing multiple stresses, including desiccation and starvation, also challenging the immune system. Since the invasion of Europe and the United States of America in 2009, it has been rapidly spreading to several European and American countries (both North and South American) and North African and Asian countries. However, globalization and global warming are allowing an altitudinal and latitudinal expansion of the species, and thus the colonization of colder regions. This review explores how D. suzukii adapts to survive during cold seasons. We focus on overwintering strategies of behavioral adaptations such as migration or sheltering, seasonal polyphenism, reproductive adaptations, as well as metabolic and transcriptomic changes in response to cold. Finally, we discuss how the continuation of climate change may promote the ability of this species to survive and spread, and what mitigation measures could be employed to overcome cold-adapted D. suzukii.

The box tree moth, Cydalima perspectalis (Walker), is an invasive pest of Hyrcanian forests in Iran. In the current study, the effects of two boxwood species, Buxus hyrcana Pojark and B. microphylla Sieb. and Zucc. (Buxales: Buxaceae), were examined on ecophysiology of the pest. The demographic parameters were evaluated based on the age-stage, two-sex life table theory. The physiological characteristics of C. perspectalis were considered through fresh/dry weights and individually/group rearing methods. The results showed that C. perspectalis larvae were able to develop, survive and reproduce on both boxwood species. The developmental times were 41.62 and 41.46 days on B. hyrcana and B. microphylla, respectively. The total lifespan did not differ on boxwood species. However, the difference of fecundity on B. hyrcana (412.82 eggs/female) and B. microphylla (286.06 eggs/female) was significant. The intrinsic rate of increase (r) and finite rate of increase (λ) were significantly higher on B. hyrcana than B. microphylla. The nutritional indices showed that the consumption index (CI) on B. hyrcana were significantly lower than on B. microphylla based on fresh/dry weights in both rearing methods. Conversely, the efficiency of conversion of digested food (ECD) and the efficiency of conversion of ingested food (ECI) on B. hyrcana were significantly higher than on B. microphylla. Despite nonsignificant differences in leaf nutrient contents (except calcium), total protein, triglyceride, and alkaline phosphatase activity were inversely different in larvae compared to adult stage on boxwood species. These findings could help to comprehensively understand the performance of the pest on boxwood species. [ABSTRACT FROM AUTHOR]

Purpose: The Nottingham Clavicle Score (NCS) is a patient-reported outcome measure developed to evaluate treatment results of clavicle, acromioclavicular and sternoclavicular joint pathologies. Valid, reliable and user-friendly translations of outcome measure instruments are needed to allow comparisons of international results. The aim of this cross-sectional study was to translate and adapt the NCS into German and evaluate the psychometric properties of the German version. Methods: The translation and cross-cultural adaptation of the NCS were completed using a 'translation–back translation" method and the final version was administered to 105 German-speaking patients. The psychometric properties of this version (NCS-G) were evaluated in terms of feasibility, reliability, validity and sensitivity to change. Results: No major differences occurred between the NCS translations into German and back into English, and no content- or linguistic-related difficulties were reported. The Cronbach's alpha for the NCS-G was 0.885, showing optimal internal consistency. The Intraclass Correlation Coefficient for test–retest reliability was 0.907 (95% CI 0.844–0.945), with a standard error of measurement of 5.59 points and a minimal detectable change of 15.50 points. The NCS-G showed moderate to strong correlation with all other investigated scales (Spearman correlation coefficient: qDASH: ρ = – 0.751; OSS: ρ = 0.728; Imatani Score: ρ = 0.646; CMS: ρ = 0.621; VAS: ρ = – 0.709). Good sensitivity to change was confirmed by an effect size of 1.17 (95% CI 0.89–1.47) and a standardized response mean of 1.23 (95% CI 0.98–1.45). Conclusions: This study demonstrated that NCS-G is reliable, valid, reproducible and well accepted by patients, showing analogous psychometric properties to the original English version. Level of evidence: Level III. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: It is still controversial whether complete displaced mid-shaft clavicle fractures should be treated with internal fixation or conservative therapy. This retrospective study aims to compare clinical outcomes of two treatment protocols., Materials and Methods: 105 patients with displaced and comminuted mid-shaft clavicle fractures were included in this study, among which 55 patients were treated conservatively and 50 patients accepted surgical fixation and were followed up for over 20 months on average. Rate of union, malunion, time taken for union, functional outcome, self-reported satisfaction and complications were compared., Results: Union rate of operative group (n=49, 98.0%) was higher than the non-operative group (n=48, 87.3%). Time taken for union in operative group (2.37±1.06 months) was shorter than the non-operative group (3.69±1.01 months). Malunion and asymmetric were only seen in the conservative group. Numbness of the shoulder was only reported in the operative group (n=23, 46.0%). Most of patients in the operative group (n=45, 90%) accepted a second operation to remove the implant. No statistically difference was found in self-reported satisfaction, Quick-DASH and Constant-Murley score. The operative group returned to work faster (1.47±0.89 to 3.34±1.37 months), regained full range of motion earlier (1.66±0.78 to 3.83±1.24 months) and regained strength faster (3.86±2.45 to 8.03±2.78 months) than the non-operative group., Conclusion: Complete displaced and comminuted mid-shaft clavicle fractures treated surgically have more reliable union and faster recovery when compared to conservatively treated fractures., (© 2024.

Drosophila suzukii (SWD) poses a threat to soft and stone fruit globally. SWD inhabits non‐crop areas adjacent to farms from where it moves into crops to cause damage. Effective IPM control strategies, considering both the crop and non‐crop area, are needed to control this economically important pest.We conducted a meta‐analysis to quantify the impacts of different non‐crop habitats around fruit farms on SWD populations, comparing abundance of SWD trapped in crop and non‐crop habitats.Overall, SWD abundance was greater in non‐crop habitats than in cropped areas and this difference was greatest in farms adjacent to woodland, or field margins containing known SWD host plants.The difference in SWD abundance between crop and non‐crop habitats was not affected by crop type but was greatest in the winter months and in conventional compared to organic farms, indicating conventional approaches can reduce relative SWD abundance.Drosophila suzukii overwinter in non‐crop habitats which provide refuge outside the cropping season. However, certain habitats support greater relative abundance of SWD than others and this is also affected by farm management. We discuss what these findings mean for effective control of SWD.

The invasive pest Drosophila suzukii is a fruit fly native to Asia that infests a wide variety of fruits. Wild plant species are major reservoirs for D. suzukii populations but their infestation rates vary greatly among geographical areas.We aimed at disentangling the relative roles of macroclimatic, landscape and local factors in the rate of D. suzukii infestation of elderberry fruits (Sambucus nigra), a major wild host plant in Europe.We collected elderberry fruits across 215 sites distributed in 13 regions from North to South of France. We counted the number of emerging D. suzukii adults and tested for the effect of macroclimatic, landscape, local biotic and abiotic variables, as well as plant traits using linear mixed models.Site latitude and mean daily maximum temperature since the beginning of the year had respectively the strongest positive and negative effects on mean infestation rates across regions. Infestation rates also increased with forest cover in a 100 m radius around sampling sites.This study shows the importance of taking into account multiple scales and factors, from the fruit characteristics (i.e. maturity) to landscape composition and macroclimatic variables, when studying the interaction between D. suzukii and its host plants.

Drosophila suzukii (Ds) is an invasive pest insect that causes severe and widespread damage to soft fruit crops. Chemical control based on topical insecticides is inefficient and harmful to consumers and the environment, prompting interest in the development of biological control measures such as insect viruses with narrow host specificity. We previously described a strain of La Jolla virus (LJV) found in moribund Ds specimens in Germany. We demonstrated a pathogenic effect following the intrathoracic injection of LJV into adult Ds flies. However, the development of an effective biocontrol product based on LJV would require the characterization of (1) virulence following oral delivery, particularly in larvae, and (2) stability under different pH and temperature conditions reflecting realistic exposure scenarios. Here we describe the pathogenicity of LJV following oral delivery to Ds adults and larvae. The oral infection of Ds adults with LJV reduced survival in a concentration-dependent manner, whereas the oral infection of Ds larvae caused the arrest of development during pupation. LJV remained stable and infectious following exposure to a broad pH range and different temperatures. We, therefore, demonstrated that LJV is promising as a candidate biological control agent against Ds. [ABSTRACT FROM AUTHOR]

This study evaluated the potential of cultural management practices (CMPs) to service sustainable social and ecological adaptation to the invasive fruit fly spotted wing drosophila (SWD). We sampled SWD and parasitoids under different CMPs in tart cherry orchards in Michigan to assess the efficacy and ecological costs of CMPs. Additionally, we interviewed Michigan tart cherry growers to understand their adaptation behaviors in response to SWD. We found no difference in SWD or parasitoid abundances among the CMPs and no effect of parasitoids on SWD abundances. Growers generally saw CMPs as supplementary to chemical sprays without the potential to reduce or replace spraying. While CMPs showed low efficacy in SWD management and growers expressed limited confidence in their efficacy, diverse cultural pest management practices should continue to be explored for their potential to support ecological diversity and adaptive agricultural systems under the threat of invasive species.

2 O3 /9.3 K2 O/1 P2 O5 /27.6 Li2O/10.4 Fe2 O3 was crystallized at temperatures in the range from 400 to 540 °C for different periods of time (2-12 h). X-ray diffraction showed cubic Li ferrite with a spinel structure, LiFe5 O8 , with small crystallites with sizes in the range from 3 to 31 nm. While the samples crystallized at 440, 480, and 500 °C reveal a disordered phase, crystallization at 540 °C indicates a phase transformation to the ordered state. Magnetization curves showed that the samples crystallized at 440 °C are superparamagnetic with very low maximum magnetization, while the samples crystallized at 480 and 500 °C show thin clear S-shaped magnetization curves with zero coercivity and hence are also superparamagnetic. By contrast, the sample crystallized at 540 °C shows a coercive field of 40 Oe and thus is ferrimagnetic. The magnetic properties can be tailored by the size of the ferrite crystals and hence by the crystallization conditions. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Emergency teams are made up of professionals of different specialities, including emergency physicians, surgeons, anesthesiologists, and nurses. Such units are characterized by the need to face unexpected situations with little time to make clinical decisions. In trauma and emergency settings, clinicians must act in a coordinated way, ensuring, at the same time, proper knowledge transfer and sharing to reach the best possible result for the patient. While such dynamics must be explicit and clear within the team, involving the patient in the decision-making process may require additional tools and procedures. Indeed, the time to engage with the patient and the family to understand the patient's wishes and treatment preferences may be limited or absent at all. While the so-called shared decision-making (SDM) stands as one of the pillars of the modern patient-centric healthcare scenario, knowledge translation and transfer dynamics may appear particularly challenging in emergency settings. Starting from an investigation of the recent literature on SDM, the paper presents a literature review of the barriers, facilitators, and knowledge translation dynamics of SDM in trauma and emergency surgery. Results assess the importance, tools, and dynamics of SDM processes. [ABSTRACT FROM AUTHOR]

Impacts of biological invasions are diverse and can have far-reaching consequences for ecosystems. The spotted wing drosophila, Drosophila suzukii, is a major invasive pest of fruits, which negatively affects fruit and wine production. However, little is known about the ecological impact of this fly species on more natural ecosystems it has invaded, such as forests. In this study, we investigated the use of potential host plants by D. suzukii at 64 sites in different forest communities in Switzerland from mid-June to midOctober 2020. We examined more than 12,000 fruits for egg deposits of D. suzukii to assess its direct impact on the plants. We recorded symptoms of fruit decay after egg deposition to determine if D. suzukii attacks trigger fruit decay. In addition, we monitored the drosophilid fauna with cup traps baited with apple cider vinegar, as we expected that D. suzukii would outnumber and potentially outcompete native controphics, especially other drosophilids. Egg deposits of D. suzukii were found on the fruits of 31 of the 39 potential host plant species studied, with 18 species showing an attack rate > 50%. Overall, fruits of Cotoneaster divaricatus (96%), Atropa bella-donna (91%), Rubus fruticosus corylifolius aggr. (91%), Frangula alnus (85%) and Sambucus nigra (83%) were attacked particularly frequently, resulting also in high predicted attack probabilities that varied among forest communities. Later and longer fruiting, black fruit colour, larger fruit size and higher pulp pH all positively affected attack rates. More than 50% of the plant species showed severe symptoms of decay after egg deposition, with higher pulp sugar content leading to more severe symptoms. The high fruit attack rate observed was reflected in a high abundance and dominance of D. suzukii in trap catches, independent of forest community and elevation. Drosophila suzukii was by far the most abundant species, accounting for 86% (81,395 individuals) of all drosophilids. The abundance of D. suzukii was negatively associated with the abundance of the native drosophilids. Our results indicate that the invasive D. suzukii competes strongly with other frugivorous species and that its presence might have far-reaching ecosystem-level consequences. The rapid decay of fruits attacked by D. suzukii leads to a loss of resources and may disrupt seed-dispersal mutualisms through the reduced consumption of fruits by dispersers such as birds.

This study utilizes and compares the performance of Gaussian and Poisson regression models to examine the associations of Tribolium confusum Jacquelin du Val (Coleoptera: Tenebrionidae) and Prostephanus truncatus (Horn) (Coleoptera: Bostrychidae) alone and in all possible combinations with Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae), at 25, 30 and 35 °C, 55% and 75% relative humidity (RH), after 65 days, 130 days and 195 days of storage on maize. The increase of temperature from 25 to 30 °C increased the emergence of insects alive and of damaged kernels, while from 30 to 35 °C decreased the aforementioned parameters. The increase of RH from 55% to 75% increased both the emerged insects alive and the damaged kernels. When O. surinamensis was examined alone it outnumbered all the other insect species and their combinations except P. truncatus alone. Regarding damaged kernels, the combination of O. surinamensis- P. truncatus was the most damaging, while the combination of O. surinamensis-T. confusum was the least damaging. The Poisson model demonstrated better performance, hence future analyses could be based upon this model to analyze this type of data. Concerning the production of frass, the combinations of P. truncatus alone, O. surinamensis-P. truncatus, and O. surinamensis-T. confusum-P. truncatus were the most damaging. Our results could be useful for the prediction of damage when different species co-infest the same commodity. Furthermore, the reveal and recording of combinations that lead to elevated damage potential may differentiate the management strategies in storage facilities. [ABSTRACT FROM AUTHOR]

Drosophila suzukii is a highly polyphagous pest species that can also attack grape. To prevent economic damage in vineyards, it is important to detect D. suzukii infestation early in order to protect grapes efficiently. Here, we firstly examined if peripheral zones adjacent to natural habitats and central zones within a vineyard differ in infestation levels, and, secondly, where within a grape cluster most eggs are laid. Among the eight infested vineyards studied, seven had higher D. suzukii infestation levels in peripheral zones adjacent to hedgerows, forests or gardens. Females laid 2.0‐fold more eggs on berries in the interior of grape clusters than on berries on the exterior of the cluster. Based on the finding that berries in the interior of grape clusters are more vulnerable, we developed a novel sampling method to estimate D. suzukii infestation level in vineyards more effectively. The so‐called 'whole cluster method' consists of a representative but random collection of five grape clusters per plot and a visual inspection of five berries each from the inner and outer part of a cluster totalling 50 checked berries per plot. We then compared our newly developed method to two established sampling methods to estimate D. suzukii infestations (i.e. 'single berry method' and 'cluster fragment method'), which rarely collect and inspect berries from the interior of clusters. In 87 comparisons conducted in 35 different plots, the 'whole cluster method' was the most sensitive sampling method as the calculated mean infestation rate was highest and it identified eggs earlier and in more samples than the other two methods. We therefore believe that the 'whole cluster method' is currently the most effective method to assess D. suzukii infestations in commercial vineyards. [ABSTRACT FROM AUTHOR]
