ABSTRACT Peanut (Arachis hypogaea L.) is a legume and requires nodulation by Bradyrhizobia to convert atmospheric N into a plant usable form. Peanut inoculants place large volumes of viable Bradyrhizobia near the emerging root of the plant to infect it ensuring N-fixation. Peanut seedlings are susceptible to feeding by thrips (Thysanoptera: Thripidae), which transmit Tospovirus leading to tomato spotted wilt (TSW) and can result in yield decline. Phorate is a common in-furrow insecticide used to reduce thrips feeding on the plants, and hence reduce the risk of TSW infection. However, placing phorate in the same furrow with living Bradyrhizobia has raised concerns about phorate potentially reducing efficacy of inoculants. Experiments were designed to test liquid and sterile peat formulations of Bradyrhizobia inoculant with two peanut cultivars in-furrow at planting, both with and without phorate insecticide to determine yield, grade, and growth parameters on peanut. Research was conducted on a non-irrigated loamy sand with no prior history of growing peanut in Tifton, GA in 2013 and 2014. There were no negative effects on peanut yield or grade, or other measured parameters when phorate was included in-furrow with inoculants. Yields with inoculants were equal or greater (up to 32% more) than non-inoculated peanut, and grade was improved (+1.2 to 1.4%) when using the liquid formulation instead of the sterile peat formulation or non-inoculated peanut. Other indicators of improved plant performance using inoculants over non-inoculated plants included the abundance and activity of nodules on the roots and time to row closure (vegetation overlap of bare soil). These data indicate there are no detrimental effects to peanut inoculant when also including phorate insecticide in-furrow.

Plant biostimulants are of interest as they can stimulate plant growth and increase resource utilization. There is still no information on the use of plant growth-promoters under variable nutritional conditions in the nursery and the effects on tomato seedling growth and plant performance after transplant. This study aimed to evaluate the suitability of gibberellic acid (GA3) or bacterial biostimulant treatments to enhance the growth and quality of greenhouse-grown tomato (Solanum lycopersicum ‘Marmande’) seedlings, fertigated with increasing nutrient rates and to assess the efficacy of these treatments on the early growth of tomato plants. During autumn 2019, tomato seedlings were inoculated with 1.5 g L−1 of TNC BactorrS13 (a commercial biostimulant containing 1.3 × 108 CFU g−1 of Bacillus spp.) or sprayed with 10−5 M GA3 and fertigated with a nutrient solution containing 0, 1, 2 and 4 g L−1 of NPK fertilizer (20-20-20) when they reached the 11th BBCH growth stage for tomato. Subsequently, the seedlings were evaluated in greenhouse cultivation for 60 days until at least the 61st BBCH growth stage (January 2020). The growth of the tomato seedlings increased curvilinearly in relation to the fertigation rates. The GA3-treated seedlings showed similar or even higher growth parameters than the control seedlings fed with 4 g L−1 of fertilizer but with half of the nutrients. The inoculation of the substrate with Bacillus spp. had negative effects in the absence of fertigation but determined a greater growth at the highest fertigation rate. The bacterial inoculum of seedlings had longer-term effects than the GA3 treatment during the plant growth, but these effects were noticeable mainly when the bacterial biostimulant was associated with the highest fertigation rate.

ABSTRACT Stem rot, also known as white mold (WM), caused by Sclerotium rolfsii Sacc., and tomato spotted wilt, caused by Tomato spotted wilt virus (TSWV), are two major disease problems in Georgia peanut (Arachis hypogaea L.) production. Current fungicides for stem rot control are very effective but expensive, and insecticides usually have little effect on TSWV, which is transmitted by thrips. Consequently, the objective of this study was to evaluate different peanut genotypes for resistance to both of these pathogens. Field test evaluations were conducted for four consecutive years (2010-13) at a site on the agronomy research farm near the Coastal Plain Experiment Station which has a long history of continuous peanut production and a high incidence of stem rot (WM) and TSWV. Results from these field tests showed significant differences among the peanut genotypes evaluated for combined resistance to both diseases. Several genotypes showed low TSWV incidence at mid-season and mid-to-late season. However by late season and after digging, the best combination of stem rot (WM) and TSWV disease resistance and highest consistent yield over years was in the runner-type peanut cultivar ‘Georgia-12Y’, along with ‘York’, ‘Georgia-07W’, and ‘Georgia-10T’.

Using a qualitative approach, based on extensive fieldwork and surveys, this article examines how participatory institutions in Nepal perform and affect local planning. The evidence points to mixed outcomes: citizen participation can improve local planning, especially with regard to achieving planning efficacy and equity; and at the same time, it sometimes yields no such effects or may produce negative effects including raising expectations, skewing priorities and producing faulty compartmentalization, besides adding to administrative complexities. This is because the anticipated benefits of citizen participation are strongly embedded in local, socio-political realities such as the degree of power exercised by the local elites, mainly politicians, a collusive nexus among them, prior history of citizen mobilization and empowerment and the degree to which citizens and civil society organizations are able to exercise their agency to countervail those forces.

Background and Purpose: Recurrent ischemic strokes increase the risk of disability and mortality. The role of conventional risk factors in recurrent strokes may change due to increased awareness of prevention strategies. The aim of this study was to explore the potential risk factors besides conventional ones which may help to affect the advances in future preventive concepts associated with one-year stroke recurrence (OSR). Methods: We analyzed 6,632 adult patients with ischemic stroke. Differences in clinical characteristics between patients with and without OSR were analyzed using multivariate logistic regression and classification and regression tree (CART) analyses. Results: Among the study population, 525 patients (7.9%) had OSR. Multivariate logistic regression analysis revealed that male sex (OR 1.243, 95% CI 1.025 – 1.506), age (OR 1.015, 95% CI 1.007 - 1.023), and a prior history of ischemic stroke (OR 1.331, 95% CI 1.096 – 1.615) were major factors associated with OSR. CART analysis further identified age and a prior history of ischemic stroke were important factors for OSR when classified the patients into three subgroups (with risks of OSR of 8.8%, 3.8%, and 12.5% for patients aged > 57.5 years, ≤ 57.5 years/with no prior history of ischemic stroke, and ≤ 57.5 years/with a prior history of ischemic stroke, respectively). Conclusions: Male sex, age, and a prior history of ischemic stroke could increase the risk of OSR by multivariate logistic regression analysis, and CART analysis further demonstrated that patients with a younger age (≤ 57.5 years) and a prior history of ischemic stroke had the highest risk of OSR.

Diving as a method of fishing is used worldwide in small-scale fisheries. However, one of the main causes of morbidity and mortality among fishermen is decompression sickness (DCS). We report the case of a 46-year-old male fisherman diver who presented with chronic inguinal pain that radiated to the lower left limb. Living and working in a fishing port in Yucatan, he had a prior history of DCS. A diagnosis of avascular necrosis in the left femoral head secondary to DCS was made via analysis of clinical and radiological findings. The necrosis was surgically resolved by a total hip arthroplasty. Dysbaric osteonecrosis is a more probable diagnosis. In this region fishermen undergo significant decompression stress in their daily fishing efforts. Further studies regarding prevalence of dysbaric osteonecrosis among small-scale fisheries divers are needed. In a community where DCS is endemic and has become an epidemic, as of late, the perception of this health risk remains low. Furthermore, training and decompression technique are lacking among the fishing communities.

The origins of attachment theory and the work of John Bowlby and Mary Ainsworth are described. Four types of child–parent attachment relationships—secure, insecure/anxious, insecure/ambivalent, and insecure/disorganized—are outlined along with the ways each type might manifest itself in the classroom. A longitudinal study, conducted by Alan Sroufe and his colleagues, of the development and effects on learning and interpersonal relationships of different child–parent attachment relationships is described. Teachers too have a history of attachment relationships that can affect how they relate to their students. The chapter describes adult attachment and how one’s attachment history might, positively or negatively, affect one’s ability to build positive, nurturing relationships with students. Specific examples of ways teachers can offset the negative effects of a student’s or their own history of insecure attachment are described.

Abstract Background This retrospective cohort study assessed the annualized incidence rate (IR) of acute pancreatitis (AP) in a nationally representative US adult population, as well as the variation in the risk of AP events across strata of triglyceride (TG) levels. Methods Data were obtained from IQVIA’s US Ambulatory Electronic Medical Records (EMR) database linked with its LRxDx Open Claims database. Inclusion criteria included ≥1 serum TG value during the overlapping study period of the EMR and claims databases, ≥1 claim in the 12-month baseline period, and ≥ 1 claim in the 12 months post index. All TG measurements were assigned to the highest category reached: < 2.26, ≥2.26 to ≤5.65, > 5.65 to ≤9.94, > 9.94, and > 11.29 mmol/L (< 200, ≥200 to ≤500, > 500 to ≤880, > 880, and > 1000 mg/dL, respectively). The outcome of interest was AP, defined as a hospitalization event with AP as the principal diagnosis. Results In total, 7,119,195 patients met the inclusion/exclusion criteria, of whom 4158 (0.058%) had ≥1 AP events in the prior 12 months. Most patients (83%) had TGs < 2.26 mmol/L (< 200 mg/dL), while < 1% had TGs > 9.94 mmol/L (> 880 mg/dL). Overall, the IR of AP was low (0.08%; 95% confidence internal [CI], 0.08–0.08%), but increased with increasing TGs (0.08% in TGs < 2.26 mmol/L [< 200 mg/dL] to 1.21% in TGs > 11.29 mmol/L [> 1000 mg/dL]). In patients with a prior history of AP, the IR of AP increased dramatically; patients with ≥2 AP events at baseline had an IR of 29.98% (95% CI, 25.1–34.9%). Conclusion The risk of AP increases with increasing TG strata; however, the risk increases dramatically among patients with a recent history of AP.
