Trade-offs constrain the success of glyphosate-free farming.

Glyphosate, the most widely used herbicide, is linked with environmental harm and there is a drive to replace it in agricultural systems. We model the impacts of discontinuing glyphosate use and replacing it with cultural control methods. We simulate winter wheat arable systems reliant on glyphosate and typical in northwest Europe. Removing glyphosate was projected to increase weed abundance, herbicide risk to the environment, and arable plant diversity and decrease food production. Weed communities with evolved resistance to non-glyphosate herbicides were not projected to be disproportionately affected by removing glyphosate, despite the lack of alternative herbicidal control options. Crop rotations with more spring cereals or grass leys for weed control increased arable plant diversity. Stale seedbed techniques such as delayed drilling and choosing ploughing instead of minimum tillage had varying effects on weed abundance, food production, and profitability. Ploughing was the most effective alternative to glyphosate for long-term weed control while maintaining production and profit. Our findings emphasize the need for careful consideration of trade-offs arising in scenarios where glyphosate is removed. Integrated Weed Management (IWM) with more use of cultural control methods offers the potential to reduce chemical use but is sensitive to seasonal variability and can incur negative environmental and economic impacts.

Single cell multi-omics characterise discrete human tendon cells populations that persist in vitro and on fibrous scaffolds.

Chronic tendinopathy represents a growing healthcare burden in the ageing global population. Curative therapies remain elusive as the mechanisms that underlie chronic inflammation in tendon disease remain unclear. Identifying and isolating key pathogenic and reparative cells is essential in developing precision therapies and implantable materials for improved tendon healing. Multiple discrete human tendon cell populations have been previously described ex vivo. To determine if these populations persist in vitro, healthy human hamstring tenocytes were cultured for 8 d on either tissue culture plastic or aligned electrospun fibres of absorbable polydioxanone. Novel single-cell surface proteomics combined with unbiased single-cell transcriptomics (CITE-Seq) was used to identify discrete tenocyte populations. 6 cell populations were found, 4 of which shared key gene expression determinants with ex vivo human cell clusters: PTX3_PAPPA, POSTN_SCX, DCN_LUM and ITGA7_NES. Surface proteomics found that PTX3_PAPPA cells were CD10+CD26+CD54+. ITGA7_NES cells were CD146+ and POSTN_SCX cells were CD90+CD95+CD10+. Culture on the aligned electrospun fibres favoured 3 cell subtypes (DCN_LUM, POSTN_SCX and PTX3_ PAPPA), promoting high expression of tendon-matrix-associated genes and upregulating gene sets enriched for TNF-a and IL-6/STAT3 signalling. Discrete human tendon cell subpopulations persisted in in vitro culture and could be recognised by specific gene and surface-protein signatures. Aligned polydioxanone fibres promoted the survival of 3 clusters, including pro-inflammatory PTX3-expressing CD10+CD26+CD54+ cells found in chronic tendon disease. These results improved the understanding of preferred culture conditions for different tenocyte subpopulations and informed the development of in vitro models of tendon disease.

Blueprints for the rational design of therapeutic mutacin 1140 variants.

Lantibiotics represent a large untapped pipeline of attractive scaffolds for the development of novel antibiotics. Saturation mutagenesis was employed to substitute every amino acid of a lantibiotic called mutacin 1140 (MU1140), creating an unbiased expression library of 418 variants that was used to study the permissiveness to mutagenesis and the "drugability" of several compounds. Contrasting previous reports, the results from this study supported that not all residues involved in lanthionine bridge formation were critical for maintaining optimal activity. While substitutions in lanthionine bridges in Ring A, C, and D invariably lead to inactive variants, permissive substitutions in Abu8 and Ala11 (Ring B) were observed, albeit infrequently. Further, the data generated suggested that the unsaturated bond from Dha5 (Ser5) may not be critically involved in Lipid-II binding but still important for conferring optimal activity. This study identified additional permissive mutations of Ser5, including Ser5His, Ser5Met, Ser5Gln, and Ser5Leu. In contrast, no permissive substitutions were identified for Dhb14, which suggested that this residue may be critical for optimal activity. Novel blueprints are proposed for directing further development of MU1140 variants and other lantibiotics, which may enable the rational design, development, manufacture, and formulation of an entirely new class of anti-infectives.

Response of Maize Hybrids With and Without Rootworm- and Drought-Tolerance to Rootworm Infestation Under Well-Watered and Drought Conditions.

Anecdotal data in the past have suggested that the effect of the western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), on maize yield is greater under drought and the effect of drought is greater under rootworm infestations, but no field experiments have controlled both moisture and rootworm levels. Field studies were conducted in 2012, 2013, and 2014 with treatments in a factorial arrangement of western corn rootworm infestation levels, and maize hybrids (with and without tolerance to drought and rootworm feeding). The experiment was repeated under well-watered and drought conditions in adjacent plots. Leaf water potential and stomatal conductance data suggested significant plant stress was achieved in the drought plots toward the end of the season each year and maize hybrids only played a minor role. In particular, in 2012 and 2013 yield was dramatically lower for the drought experiment than for the well-watered experiment. However, the impacts of rootworm infestation level and maize hybrids on water potential, stomatal conductance, and yield were variable across years and between experiments. In fact, the only year that the main effect of rootworm infestation levels significantly impacted yield was in 2014, when an extremely high infestation level was added and this was only for the well-watered portion of the experiment. Overall, rootworm infestation level played a relatively minor role in maize productivity and it did not appear that soil moisture level influenced that to a large degree.

Natural pathology of the captive chimpanzee (Pan troglodytes): A 35-year review.

We present the spontaneous pathological lesions identified as a result of necropsy or biopsy for 245 chimpanzees (Pan troglodytes) over a 35-year period. A review of the pathology database was performed for all diagnoses on chimpanzees from 1980 to 2014. All morphologic diagnoses, associated system, organ, etiology, and demographic information were reviewed and analyzed. Cardiomyopathy was the most frequent lesion observed followed by hemosiderosis, hyperplasia, nematodiasis, edema, and hemorrhage. The most frequently affected systems were the gastrointestinal, cardiovascular, urogenital, respiratory, and lymphatic/hematopoietic systems. The most common etiology was undetermined, followed by degenerative, physiologic, neoplastic, parasitic, and bacterial. Perinatal and infant animals were mostly affected by physiologic etiologies and chimpanzee-induced trauma. Bacterial and physiologic etiologies were more common in juvenile animals. Degenerative and physiologic (and neoplastic in geriatric animals) etiologies predominated in adult, middle aged, and geriatric chimpanzees.

Patient and physician views of accompanied consultations in occupational health.

BACKGROUND: Accompanied (triadic) consultations, or consultations where a third person is present, are poorly researched and little research has been carried out in an occupational health (OH) setting. AIMS: To elicit the views of patients and OH physicians about accompanied consultations. METHODS: OH receptionists gave a self-administered questionnaire to patients after they attended OH consultations with a companion. We interviewed participating OH physicians to ascertain their views on accompanied consultations. RESULTS: Twenty-six patient questionnaires were completed (response rate 52%). Seventy-three per cent (19) of responders were accompanied by a spouse and 12% (3) by non-family members. Patients reported their companion was helpful with recall of information (100%), supportive (100%), provided extra information to the physician (81%) and enabled them to discuss the outcome afterwards (92%). In two consultations, the companion attended to provide support on procedural matters. Patients were not concerned that the consultation might involve sensitive discussion or physical examination. OH physicians reported concerns that the companion would make the consultation more difficult or influence its outcome. They felt that written information, guidelines and training in how to manage accompanied consultations would be useful. CONCLUSIONS: Patients who attended OH consultations with a companion felt the companion was beneficial to the consultation and did not have concerns about personal issues. OH physicians felt that further guidance and training on accompanied consultations would be useful. Written information could usefully be provided to patients attending an OH consultation with a companion.

The Effect of Western Corn Rootworm (Coleoptera: Chrysomelidae) and Water Deficit on Maize Performance Under Controlled Conditions.

The western corn rootworm, Diabrotica virgifera virgifera LeConte, is the most important insect of maize, Zea mays L., but knowledge of its interaction with water deficit on maize production is lacking. A series of greenhouse experiments using three infestation levels of the western corn rootworm, D. virgifera virgifera, under well-watered, moderately dry, and very dry soil moisture levels were conducted to quantify the interaction of western corn rootworm and soil water deficit on B73×Mo17 maize growth and physiology. Three separate experiments were conducted. Soil moisture regimes were initiated 30 d postplanting for experiments using neonate and second-instar larvae and 30 d postinfestation in the experiment using eggs. In the neonate and second-instar experiments, there were no significant differences among western corn rootworm levels in their effects on leaf water potential, shoot dry weight, and root dry weight. The interaction of western corn rootworm and soil moisture significantly impacted the larval recovery in the neonate experiment, but no other significant interactions were documented between soil moisture levels and rootworm infestation levels. Overall, the results indicate that under the conditions of these experiments, the effect of water deficit was much greater on plants than the effect of western corn rootworm and that the interactions between water deficit and western corn rootworm levels minimally affected the measured parameters of plant performance.

Accompanied consultations in occupational health.

BACKGROUND: Accompanied consultations are often reported as difficult by occupational physicians but have not been studied in the occupational health setting. AIMS: To collect information about accompanied consultations and the impact of the companion on the consultation. METHODS: We collected data on all accompanied consultations by two occupational physicians working in a private sector occupational health service over the course of 16 months. Accompanied consultations were matched to non-accompanied consultations for comparison. RESULTS: We collected data on 108 accompanied consultations. Accompanied consultations were more likely to be connected with ill health retirement (P < 0.01), have a neurological diagnosis or multiple diagnoses (P < 0.01), be rated as complex (P < 0.01) and take longer than 30 minutes (P < 0.01) than non-accompanied consultations. Over half of the companions (54%) were a spouse or partner. An impact by the companion was recorded in 81% of consultations but this was most frequently that they had provided information (56%) and in over a quarter the impact was recorded as helpful. Interruptions were recorded in 28% of accompanied consultations but only 6% of consultations had free text suggesting that the consultation or companion was difficult. CONCLUSIONS: Accompanied consultations are likely to be more challenging in terms of the reason for referral, the presenting medical problems, the complexity of the case and the duration of the consultation. However, the companion is more likely to be of benefit than cause difficulty. Occupational health practitioners may benefit from better understanding of accompanied consultations and guidance on their management.

Alopecia in Outdoor Group- and Corral-Housed Baboons (Papio hamadryas spp.).

Alopecia has been reported to occur in several species of captive NHP. Much of this research has focused on macaque monkeys; whether other primate species such as baboons are affected similarly is unknown. Because alopecia can be a focus of inspectors and a possible marker of wellbeing, the purpose of the current study was to survey the occurrence of alopecia in 2 baboon populations and to identify potential risk factors. Subjects were 262 group-housed and 279 corral-housed baboons. Alopecia was assessed cage-side (group-housed) and on sedated animals (corral-housed). Although alopecia was mild in both populations, there were significant effects of season and sex. Alopecia was greater in the winter (group-housed) and the fall (corral-housed) and in female baboons. In addition, the group-housed baboons showed a significant negative effect of age and a lesser effect of group size on alopecia. These results demonstrate that variables other than those associated with animal management practices can affect hair loss in baboons.

Correlation between presence of Trypanosoma cruzi DNA in heart tissue of baboons and cynomolgus monkeys, and lymphocytic myocarditis.

Trypanosoma cruzi, the causative agent of Chagas' disease, preferentially infects cardiac and digestive tissues. Baboons living in Texas (Papio hamadryas) and cynomolgus monkeys (Macaca fascicularis) have been reported to be infected naturally with T. cruzi. In this study, we retrospectively reviewed cases of animals that were diagnosed with lymphocytic myocarditis and used a polymerase chain reaction (PCR)-based method (S36/S35 primer set) to amplify T. cruzi DNA from archived frozen and formalin-fixed paraffin-embedded (FFPE) cardiac tissues. We show that the PCR method is applicable in archived frozen and FFPE tissues and the sensitivity is in the femtogram range. A positive correlation between PCR positivity and lymphocytic myocarditis in both baboons and cynomolgus monkeys is shown. We also show epicarditis as a common finding in animals infected with T. cruzi.

Mortality in captive baboons (Papio spp.): a-23-year study.

BACKGROUND: We report the causes of mortality for 4350 captive baboons that died or were euthanized due to natural causes during a 23 year period at the Southwest National Primate Research Center. METHODS: Necropsy records were retrieved and reviewed to determine a primary cause of death or indication for euthanasia. Data was evaluated for morphological diagnosis, organ system, and etiology. RESULTS: The 20 most common morphologic diagnoses accounted for 76% of the cases, including stillborn (10.8%); colitis (8.6%); hemorrhage (8.4%); ulcer (5.2%); seizures (4.7%); pneumonia (4.2%); inanition (4.1%); dermatitis (3.8%); spondylosis (3.3%); and amyloidosis (3.0%). The digestive system was most frequently involved (21.3%), followed by the urogenital (20.3%), cardiovascular (12.2%), and multisystem disease (10.3%). An etiology was not identified in approximately one-third of cases. The most common etiologies were trauma (14.8%), degenerative (9.5%), viral (8.7%), and neoplastic/proliferative (7.0%). CONCLUSION: This information should be useful for individuals working with baboons.

Abnormal behavior and associated risk factors in captive baboons (Papio hamadryas spp.).

Abnormal behavior, ranging from motor stereotypies to self-injurious behavior, has been documented in captive nonhuman primates, with risk factors including nursery rearing, single housing, and veterinary procedures. Much of this research has focused on macaque monkeys; less is known about the extent of and risk factors for abnormal behavior in baboons. Because abnormal behavior can be indicative of poor welfare, either past or present, the purpose of this study was to survey the presence of abnormal behavior in captive baboons and to identify potential risk factors for these behaviors with an aim of prevention. Subjects were 144 baboons (119 females, 25 males) aged 3-29 (median = 9.18) years temporarily singly housed for research or clinical reasons. A 15-min focal observation was conducted on each subject using the Noldus Observer® program. Abnormal behavior was observed in 26% of the subjects, with motor stereotypy (e.g., pace, rock, swing) being the most common. Motor stereotypy was negatively associated with age when first singly housed (P < 0.005) while self-directed behavior (e.g., hair pull, self-bite) was positively associated with the lifetime number of days singly housed (P < 0.05) and the average number of blood draws per year (P < 0.05). In addition, abnormal appetitive behavior was associated with being male (P < 0.05). Although the baboons in this study exhibited relatively low levels of abnormal behavior, the risk factors for these behaviors (e.g., social restriction, routine veterinary procedures, and sex) appear to remain consistent across primate species.

Reverse translation of the rodent 5C-CPT reveals that the impaired attention of people with schizophrenia is similar to scopolamine-induced deficits in mice.

Attentional dysfunction in schizophrenia (SZ) is a core deficit that contributes to multiple cognitive deficits and the resulting functional disability. However, developing procognitive therapeutics for neuropsychiatric disorders have been limited by a 'translational gap'--a lack of cognitive paradigms having cross-species translational validity and relevance. The present study was designed to perform an initial validation of the cross-species homology of the 5-choice Continuous Performance Test (5C-CPT) in healthy nonpsychiatric comparison subjects (NCS), SZ patients and mice under pharmacologic challenge. The 5C-CPT performance in SZ patients (n=20) was compared with age-matched NCS (n=23). The effects of the general muscarinic receptor antagonist scopolamine on mice (n=21) performing the 5C-CPT were also assessed. SZ subjects exhibited significantly impaired attention in the 5C-CPT, driven by reduced target detection over time and nonsignificantly increased impulsive responding. Similarly, scopolamine significantly impaired attention in mice, driven by reduced target detection and nonsignificantly increased impulsive responding. Scopolamine also negatively affected accuracy and speed of responding in mice, although these measures failed to differentiate SZ vs. NCS. Thus, mice treated with scopolamine exhibited similar impairments in vigilance as seen in SZ, although the differences between the behavioral profiles warrant further study. The availability of rodent and human versions of this paradigm provides an opportunity to: (1) investigate the neuroanatomic, neurochemical and genomic architecture of abnormalities in attention observed in clinical populations such as SZ; (2) develop and refine animal models of cognitive impairments; and (3) improve cross-species translational testing for the development of treatments for these impairments.

Assessing the sensitivity of habitats to fishing: from seabed maps to sensitivity maps.

In the Welsh part of the Irish Sea, a method was developed for assessing the sensitivity of different seabed habitats to existing fishing activities, across a range of potential fishing intensities. The resistance of 31 habitats and their associated biological assemblage to damage by 14 categories of fishing activity were assessed along with the rate at which each habitat would recover following impact (resilience). Sensitivity was scored based on a combination of the resistance of a habitat to damage and its subsequent rate of recovery. The assessments were based, wherever possible, on scientific literature, with expert judgement used to extrapolate results to habitat and gear combinations not directly examined in the published literature. The resulting sensitivity matrices were then subject to further peer review at a series of workshops. Following consensus on the habitat sensitivity, these data were combined with the most resolved sea-floor habitat maps. These habitat sensitivity maps can help inform the development of site-specific management plans, as well as having a place in spatial planning and aiding managers in developing dialogue with other stakeholders. A case study of their application is provided.

The Manchester-Oxford Foot Questionnaire (MOXFQ): Development and validation of a summary index score.

OBJECTIVES: The Manchester-Oxford Foot Questionnaire (MOXFQ) is a validated 16-item, patient-reported outcome measure for evaluating outcomes of foot or ankle surgery. The original development of the instrument identified three domains. This present study examined whether the three domains could legitimately be summed to provide a single summary index score. METHODS: The MOXFQ and Short-Form (SF)-36 were administered to 671 patients before surgery of the foot or ankle. Data from the three domains of the MOXFQ (pain, walking/standing and social interaction) were subjected to higher order factor analysis. Reliability and validity of the summary index score was assessed. RESULTS: The mean age of the participants was 52.8 years (sd 15.68; 18 to 89). Higher order principle components factor analysis produced one factor, accounting for 74.7% of the variance. The newly derived single index score was found to be internally reliable (α = 0.93) and valid, achieving at least moderate correlations (r ≥ 0.5, p < 0.001) with related (pain/function) domains of the SF-36. CONCLUSIONS: Analyses indicated that data from the MOXFQ can be presented in summary form. The MOXFQ summary index score (MOXFQ-Index) provides an overall indication of the outcomes of foot and ankle surgery. Furthermore, the single index reduces the number of statistical comparisons, and hence the role of chance, when exploring MOXFQ data.

Expanded carrier screening in reproductive healthcare: perspectives from genetics professionals.

STUDY QUESTION: How do genetics professionals assess the potential benefits and challenges of expanded carrier screening (ECS) in reproductive healthcare? SUMMARY ANSWER: Genetics professionals believe that current ECS products have major limitations and are not ready for routine use in reproductive healthcare. WHAT IS KNOWN ALREADY: Non-targeted approaches to carrier screening have been met with uneven enthusiasm from relevant professional organizations. With declining genotyping costs, it is reasonable to expect that the number of genetic conditions evaluated by carrier-screening products will continue to increase. Reproductive healthcare providers will play a critical role in the adoption of ECS and need to be prepared for the potential challenges that lie ahead. STUDY DESIGN, SIZE, DURATION: Focus groups were convened at six academic medical centers in the USA in March 2011 to examine genetics professionals' views on ECS. PARTICIPANTS/MATERIALS, SETTING, METHODS: Forty genetic professionals participated in six focus groups for this study. A clinical case report was presented to each focus group to examine participants' opinions about the use of highly multiplexed forms of carrier screening in reproductive healthcare. Focus group transcripts were analyzed for major themes and thematic density across sites using qualitative data analysis software (ATLAS.ti v5.8). MAIN RESULTS AND THE ROLE OF CHANCE: Participants believed that current ECS products have major limitations pertaining to the analysis of select alleles and genetic mutations. Participants highlighted multiple interpretive and counseling challenges that reproductive healthcare providers may face in communicating ECS results to patients. Participants stressed the importance of communicating these and other limitations to patients before recommending ECS. Participants recommended collaboration with genetic counselors and medical geneticists in providing ECS. LIMITATIONS, REASONS FOR CAUTION: To the extent that ECS products have not been widely used to date, participants may have had limited familiarity and direct clinical experience with these products. Given that this study was conducted with genetic professionals from academic medical centers in the USA, participant perspectives may not be representative of professional practices and norms in other healthcare settings. WIDER IMPLICATIONS OF THE FINDINGS: In considering the use of ECS products in their practices, reproductive healthcare providers may find it helpful to consider the perspectives of genetics professionals. These specialists have considerable experience with diverse forms of genetic testing and can provide valuable insights regarding new genomic risk assessment tools such as ECS.

Disección sub-mucosa endoscópica en cáncer gástrico incipiente / Endoscopic sub-mucosal dissection for early gastric cancer

Introduction: Gastric cancer is the leading cause of mortality in Chile and the survival rates are in direct relation with the stage of the disease. Early gastric cancer is defined as that confined to the mucosa or submucosa, regardless of the presence or absence of regional lymph node metastases and it is characterized for its great prognosis, with a survival rate of more than 90 percent at ten years of follow up. Endoscopic submucosal dissection is a technique described and developed in Japan that allows the endoscopic complete en-bloc resection of lesions of more than 2 cm with tumor cell-negative margins. Method: Databases (Pubmed, EBSCO, Cochrane) were reviewed under the terms "gastric cancer", "early gastric cancer", "endoscopic submucosal dissection". Results: The results of published series demonstrate survival rates comparable to standard surgery with less morbidity and without mortality. The present revision describes the endoscopic submucosal dissection technique in early gastric cancer, its indications, the results, the analysis of the resected pieces, the complications and the follow up of the patients. Conclusion: Endoscopic submucosal dissection is a feasible technique, with excellent oncologic results and low morbidity in selected patients.

Método: Se realizó una búsqueda en las bases de datos (Pubmed, EBSCO, Cochrane) bajo las palabras clave: "gastric cáncer", "early gastric cáncer", "endoscopic submucosal dissection". Resultados: Los resultados de grandes series demuestran una sobrevida comparable a la cirugía clásica, con menor morbilidad y sin mortalidad asociada. La presente revisión describe la técnica de disección sub-mucosa endoscópica en cáncer gástrico incipiente, sus indicaciones, los resultados, el análisis de las piezas resecadas, las complicaciones y el modo de seguimiento de los pacientes. Conclusión: La disección sub-mucosa endoscópica es una alternativa válida, con buenos resultados a largo plazo en pacientes debidamente seleccionados.

Responsiveness of the Manchester-Oxford Foot Questionnaire (MOXFQ) compared with AOFAS, SF-36 and EQ-5D assessments following foot or ankle surgery.

The responsiveness of the Manchester-Oxford Foot Questionnaire (MOXFQ) was compared with foot/ankle-specific and generic outcome measures used to assess all surgery of the foot and ankle. We recruited 671 consecutive adult patients awaiting foot or ankle surgery, of whom 427 (63.6%) were female, with a mean age of 52.8 years (18 to 89). They independently completed the MOXFQ, Short-Form 36 (SF-36) and EuroQol (EQ-5D) questionnaires pre-operatively and at a mean of nine months (3.8 to 14.4) post-operatively. Foot/ankle surgeons assessed American Orthopaedic Foot and Ankle Society (AOFAS) scores corresponding to four foot/ankle regions. A transition item measured perceived changes in foot/ankle problems post-surgery. Of 628 eligible patients proceeding to surgery, 491 (78%) completed questionnaires and 262 (42%) received clinical assessments both pre- and post-operatively. The regions receiving surgery were: multiple/whole foot in eight (1.3%), ankle/hindfoot in 292 (46.5%), mid-foot in 21 (3.3%), hallux in 196 (31.2%), and lesser toes in 111 (17.7%). Foot/ankle-specific MOXFQ, AOFAS and EQ-5D domains produced larger effect sizes (> 0.8) than any SF-36 domains, suggesting superior responsiveness. In analyses that anchored change in scores and effect sizes to patients' responses to a transition item about their foot/ankle problems, the MOXFQ performed well. The SF-36 and EQ-5D performed poorly. Similar analyses, conducted within foot-region based sub-groups of patients, found that the responsiveness of the MOXFQ was good compared with the AOFAS. This evidence supports the MOXFQ's suitability for assessing all foot and ankle surgery.
