Growing-Season Synoptic and Phenological Controls on Heat Fluxes over Forest and Cropland Sites in the Midwest U.S. Corn Belt
Authors: Hiestand Mikael P. , Carleton Andrew M. 
Published: December 2019

AbstractSpatial variations in land use/land cover (LULC) in the Midwest U.S. Corn Belt—specifically, deciduous forest and croplands—have been suggested as influencing convective rainfall through mesoscale circulations generated in the atmosphere’s boundary layer. However, the contributing role of latent and sensible heat fluxes for these two LULC types, and their modulation by synoptic weather systems, have not been determined. This study compares afternoon averages of convective fluxes at two AmeriFlux towers in relation to manually determined synoptic pressure patterns covering the nine growing seasons (1 May–30 September) of 1999–2007. AmeriFlux tower U.S.-Bo1 in eastern Illinois represents agricultural land use—alternating between maize and soybean crops—and AmeriFlux tower U.S.-MMS in south-central Indiana represents deciduous forest cover. Phenologically, the latent and sensible heat fluxes vary inversely across the growing season, and the greatest flux differences between cropland and deciduous forest occur early in the season. Differences in the surface heat fluxes between crop and forest LULC types vary in magnitude according to synoptic type. Moreover, statistically significant differences in latent and sensible heat between the forest and cropland sites occur for the most frequently occurring synoptic pattern of a low pressure system to the west and high pressure to the east of the Corn Belt. The present study lays the groundwork for determining the physical mechanisms of enhanced convection in the Corn Belt, including how LULC-induced mesoscale circulations might interact with synoptic weather patterns to enhance convective rainfall.
Climate Change, Temperature, and Homicide: A Tale of Two Cities, 1895–2015

Published: December 2019

AbstractIt has been argued that the temperature increase caused by anthropogenic climate change will produce a significant increase in violent crime. Support for that prediction is often based on statistical analyses of seasonal temperature and crime data cycles across days, months, and quarters and sometimes on large geographic areas. Within-year temperature changes are very large, however, relative to the 30-yr temperature increases employed to measure climate change. In addition, because temperature trends associated with climate change vary geographically, analyses should employ small geographic units for which temperature changes are measured over yearly intervals and for long periods of time. To address these conditions, this study examined the long-term temperature–crime association for homicides in New York and London for 1895–2015. Consistent with previous studies examining seasonal weather and crime patterns, we found a positive correlation between annual homicide rates and temperature, but only at the bivariate level. This relationship became statistically insignificant in both New York and London when gross domestic product is controlled. Moreover, the bivariate relationship between temperature and homicide is statistically insignificant when correcting for nonstationarity. Thus, it does not appear that climate change has led to higher rates of homicide in New York and London over the long term. These nonfindings are important because they suggest that studies of climate change and violence might do well to consider alternative mechanisms that mediate the relationship between climate change and violence.
Human Performance Benefits of The Automation Transparency Design Principle

Published: December 2019

Objective Test the automation transparency design principle using a full-scope nuclear power plant simulator. Background Automation transparency is a long-held human factors design principle espousing that the responsibilities, capabilities, goals, activities, and/or effects of automation should be directly observable in the human–system interface. The anticipated benefits of transparency include more effective reliance, more appropriate trust, better understanding, and greater user satisfaction. Transparency has enjoyed a recent upsurge in use in the context of human interaction with agent-oriented automation. Method Three full-scope nuclear power plant simulator studies were conducted with licensed operating crews. In the first two experiments, transparency was implemented for interlocks, controllers, limitations, protections, and automatic programs that operate at the local component level of the plant. In the third experiment, procedure automation assumed control of plant operations and was represented in dedicated agent displays. Results Results from Experiments 1 and 2 appear to validate the human performance benefits of automation transparency for automation at the component level. However, Experiment 3 failed to replicate these findings for automation that assumed control for executing procedural actions. Conclusion Automation transparency appears to yield expected benefits for component-level automation, but caution is warranted in generalizing the design principle to agent-oriented automation. Application The automation transparency design principle may offer a powerful means of compensating for the detrimental impacts of hidden automation influence at the component level of complex systems. However, system developers should exercise caution in assuming that the principle extends to agent-oriented automation.

Published: December 2019

Objectives: Cognitive difficulties or impairment may be an early step in the development of dementia. Several modifiable risk factors for cardiovascular disease (CVD) may also increase the risk of dementia. The objective of our study was to compare adults with subjective cognitive impairment (SCI), using the Behavioral Risk Factor Surveillance System (BRFSS) cognitive disability measure, with adults who reported CVD. Methods: We examined data on 3 key outcomes among 302 008 adult respondents aged ≥45 in the 2017 BRFSS: respondents with SCI only, respondents with CVD only, and respondents with both conditions. We compared measures of disability, quality of life, access to health care, and a composite measure of the following 7 risk factors: current smoking, diabetes, high cholesterol, hypertension, inadequate fruit and vegetable consumption, obesity, and sedentary lifestyle. We also estimated population-attributable risk (PAR). Results: Among respondents, 7.9% reported SCI only, 11.1% reported CVD only, and 3.2% reported both conditions, with differences by age and sex. Adults with SCI only were more likely than adults with CVD only to report other disability, worse access to health care, and poorer quality of life, even though adults with CVD were older. Compared with adults with neither condition, adults with any of the 3 outcomes were more likely to report having each of the 7 risk factors; we found a linear association with an increasing number of risk factors. Five or 6 risk factors contributed to PARs for each of the 3 key outcomes. PARs for SCI only were highest for ever smoking (17.2%) and sedentary lifestyle (12.8%), whereas for CVD only, PARs were highest for hypertension (35.5%) and high cholesterol (22.9%). Conclusion: Despite differences between adults with SCI and adults with CVD in several demographic and health-related measures, the overall similarity in PARs for SCI and CVD suggests potential benefits from using effective CVD interventions to address SCI.
The Brazilian Union Movement in the Twenty-first Century: The PT Governments, the Coup, and the Counterreforms
Authors: Galvão Andréia , Marcelino Paula 
Published: December 2019

Unionism, an allied, albeit subordinate, force in the neodevelopmentalist political front of the governments of Lula da Silva and Dilma Rousseff, was relatively absent from the mobilizations against or in favor of Dilma’s impeachment compared with other social movements and sought to resist and, in a way, realign itself to counter the counterreforms of Michel Temer’s government. Although union and popular demonstrations have multiplied, the absence of a unified strategy in the face of the coup and the reforms have weakened the possibilities of union resistance, and losses for workers have accumulated. O sindicalismo foi uma força aliada, ainda que subordinada, na frente política neodesenvolvimentista dos governos de Lula da Silva e Dilma Rousseff, foi uma força política relativamente ausente nas mobilizações contra ou a favor do impeachment de Dilma, se comparado a outros movimentos sociais e tem procurado resistir e, de certo modo, se realinhar, para enfrentar as contrarreformas do governo de Michel Temer. No entanto, apesar de as manifestações sindicais e populares terem se multiplicado, a ausência de uma estratégia unificada diante do golpe e das reformas fragilizou as possibilidades de resistência sindical e as perdas para os trabalhadores têm se acumulado.
Patellofemoral Pain in Adolescents: Understanding Patellofemoral Morphology and Its Relationship to Maltracking
Authors: Fick Cameron N. , Grant Camila , Sheehan Frances T. 
Published: December 2019

Background:Developing bone is highly adaptable and, as such, is susceptible to pathological shape deformation. Thus, it is imperative to quantify if changes in patellofemoral morphology are associated with adolescent-onset patellofemoral pain, as a pathway to improve our understanding of this pain’s etiology.Purpose:To quantify and compare patellofemoral morphology in adolescent patients with patellofemoral pain with matched healthy adolescent controls and determine if a relationship exists between patellofemoral shape and kinematics (measured during active flexion-extension).Study Design:Cross-sectional study; Level of evidence, 3.Methods:Using 3-dimensional static magnetic resonance images acquired during a previous study, we measured patellar, trochlear, and lateral patellar width; trochlear and patellar depth; Wiberg index; patellar-height ratio; lateral trochlear inclination; cartilage length; and lateral femoral shaft length. Student t test was used to compare shape parameters between adolescents with patellofemoral pain and controls. Pearson correlations and stepwise linear regression models were used to explore the relationship among morphology, kinematics (medial-lateral shift/tilt), and pain.Results:Relative to controls, adolescents with patellofemoral pain had larger sulci (mean ± SD, 6.6 ± 0.7 vs 6.0 ± 1.1 mm; 95% CI, 0.6 mm; P = .043; d = 0.66), lateral patellar width (23.1 ± 2.4 vs 21.4 ± 2.6 mm; 95% CI, 1.6 mm; P = .033; d = 0.70), and patella-trochlear width ratio (1.2 ± 0.1 vs 1.1 ± 0.1; 95% CI, 0.1; P < .001; d = 1.26). Shape correlated with kinematics in both cohorts and in the entire population. In the patellofemoral pain group, lateral shaft length ( r = 0.518; P = .019), Wiberg index ( r = 0.477; P = .033), and patellar-height ratio ( r = −0.582; P = .007) were correlated with medial shift. A moderate correlation existed between patellar-height ratio and lateral patellar tilt ( r = 0.527; P = .017). Half of the variation in patellar shift in the patellofemoral pain cohort was explained by the patellar-height ratio and Wiberg index ( R2= 0.487; P = .003). Linear correlations with pain were not found.Conclusion:This study provides direct evidence that patellofemoral morphology is altered and influences maltracking in adolescents with patellofemoral pain, highlighting the multifactorial etiology of this pain. Neither morphology nor kinematics (measured during active flexion-extension) correlated with pain. Both increases and decreases in these parameters likely lead to pain, negating a direct linear correlation.
The importance of systematic point-of-care ultrasound for chest pain with ST-segment elevation: A case report of takotsubo cardiomyopathy precipitated by spontaneous pneumothorax
Authors: Kim Yoon-Seop , Cha Yong Sung 
Published: December 2019

Introduction: Patients with chest pain and concomitant ST-segment elevation on an electrocardiogram should be identified as having suspected ST-segment elevation myocardial infarction. However, various etiologies cause ST-segment elevation other than ST-segment elevation myocardial infarction, such as takotsubo cardiomyopathy. Case presentation: Here we report the case of a 77-year-old man who requested transport by helicopter emergency medical service for ST-segment elevation myocardial infarction but was consequently diagnosed with takotsubo cardiomyopathy due to spontaneous pneumothorax. En route, findings of electrocardiogram as well as focused cardiac point-of-care ultrasound could not distinguish takotsubo cardiomyopathy from ST-segment elevation myocardial infarction, but a subsequent point-of-care ultrasound could reveal occult pneumothorax, which ultimately revealed to be the culprit stress factor of takotsubo cardiomyopathy causing ST-segment elevation myocardial infarction–alike presentation. After treatment with a closed thoracostomy, he recovered from the takotsubo cardiomyopathy and pneumothorax and was discharged without any complications. Discussion and conclusion: We should consider takotsubo cardiomyopathy a disease with ST-segment elevation and spontaneous pneumothorax as one of its precipitating stressors. To clarify the diagnosis, point-of-care ultrasound using a systematic rather than region-of-interest approach may be a useful method in the emergency department.

Published: December 2019

Background: Talus fractures are severe injuries typically occurring after high-energy trauma. As a result, associated injuries to different anatomic sites and organ systems occur with high frequency. The objective of this study was to determine what injuries occur with high incidence in patients presenting with major fractures of the talus and to identify clinical injury patterns that may warrant special attention in these patients. Methods: We performed a retrospective review of patients presenting to 3 level 1 trauma centers with fractures of the talar neck, body, or head over a 14-year period. Patient charts were reviewed for associated orthopedic and nonorthopedic injuries identified during the initial patient encounter and hospitalization. Results: In total, 262 fractures in 258 unique patients met criteria for inclusion. Overall, 33.3% of talus fractures occurred in isolation. One or more associated injuries were identified in the remainder of cases (66.7%). The incidence of associated injuries was similar across fracture patterns. Mean total number of injuries per patient was 2.2 (range, 0-15). The ipsilateral foot was the most frequent site of associated orthopedic injury. Noncontiguous injuries occurred in 36% of cases. Lumbar spine injury occurred in 10.5% of cases. Lower extremity vascular injury was uncommon but bore significant association with open talus fractures. Conclusion: Talus fractures are commonly associated with injuries to different anatomic sites and organ systems. A similar rate of lumbar spine trauma may occur with major talus fractures as has been historically associated with calcaneal fractures. Thorough evaluation and a high index of suspicion are necessary when evaluating patients with major fractures of the talus to avoid missing concomitant injuries. Level of Evidence: Level IV, retrospective case series.

AbstractMore than 0.6 million people suffer from disabling migraines in Greece causing a dramatic work loss, but only a small proportion of migraineurs attend headache centres, most of them being treated by non-experts. On behalf of the Hellenic Headache Society, we report here a consensus on the diagnosis and treatment of adult migraine that is based on the recent guidelines of the European Headache Federation, on the principles of Good Clinical Practice and on the Greek regulatory affairs. The purposes are three-fold: (1) to increase awareness for migraine in Greece; (2) to support Greek practitioners who are treating migraineurs; and (3) to help Greek migraineurs to get the most appropriate treatment. For mild migraine, symptomatic treatment with high dose simple analgesics is suggested, while for moderate to severe migraines triptans or non-steroidal anti-inflammatory drugs, or both, should be administered following an individually tailored therapeutic strategy. A rescue acute treatment option should always be advised. For episodic migraine prevention, metoprolol (50–200 mg/d), propranolol (40–240 mg/d), flunarizine (5–10 mg/d), valproate (500–1800 mg/d), topiramate (25–100 mg/d) and candesartan (16–32 mg/d) are the drugs of first choice. For chronic migraine prevention topiramate (100-200 mg/d), valproate (500–1800 mg/d), flunarizine (5–10 mg/d) and venlafaxine (150 mg/d) may be used, but the evidence is very limited. Botulinum toxin type A and monoclonal antibodies targeting the CGRP pathway (anti-CGRP mAbs) are recommended for patients suffering from chronic migraine (with or without medication overuse) who failed or did not tolerate two previous treatments. Anti-CGRP mAbs are also suggested for patients suffering from high frequency episodic migraine (≥8 migraine days per month and less than 14) who failed or did not tolerate two previous treatments.

AbstractBackgroundThe dominant fungi in arid grasslands and shrublands are members of the Ascomycota phylum. Ascomycota fungi are important drivers in carbon and nitrogen cycling in arid ecosystems. These fungi play roles in soil stability, plant biomass decomposition, and endophytic interactions with plants. They may also form symbiotic associations with biocrust components or be latent saprotrophs or pathogens that live on plant tissues. However, their functional potential in arid soils, where organic matter, nutrients and water are very low or only periodically available, is poorly characterized.ResultsFive Ascomycota fungi were isolated from different soil crust microhabitats and rhizosphere soils around the native bunchgrassPleuraphis jamesiiin an arid grassland near Moab, UT, USA. Putative genera wereConiochaeta, isolated from lichen biocrust,Embellisiafrom cyanobacteria biocrust, Chaetomiumfrom below lichen biocrust,Phomafrom a moss microhabitat, andAspergillusfrom the soil. The fungi were grown in replicate cultures on different carbon sources (chitin, native bunchgrass or pine wood) relevant to plant biomass and soil carbon sources. Secretomes produced by the fungi on each substrate were characterized. Results demonstrate that these fungi likely interact with primary producers (biocrust or plants) by secreting a wide range of proteins that facilitate symbiotic associations. Each of the fungal isolates secreted enzymes that degrade plant biomass, small secreted effector proteins, and proteins involved in either beneficial plant interactions or virulence.AspergillusandPhomaexpressed more plant biomass degrading enzymes when grown in grass- and pine-containing cultures than in chitin.ConiochaetaandEmbellisiaexpressed similar numbers of these enzymes under all conditions, whileChaetomiumsecreted more of these enzymes in grass-containing cultures.ConclusionsThis study of Ascomycota genomes and secretomes provides important insights about the lifestyles and the roles that Ascomycota fungi likely play in arid grassland, ecosystems. However, the exact nature of those interactions, whether any or all of the isolates are true endophytes, latent saprotrophs or opportunistic phytopathogens, will be the topic of future studies.

AbstractBackgroundEndoscopic treatment of post-cholecystectomy biliary strictures (PCBS) with multiple plastic biliary stents placed sequentially is a minimally invasive alternative to surgery but requires multiple interventions. Temporary placement of a single fully-covered self-expanding metal stent (FCSEMS) may offer safe and effective treatment with fewer re-interventions. Long-term effectiveness of treatment with FCSEMS to obtain PCBS resolution has not yet been studied.MethodsIn this prospective multi-national study in patients with symptomatic benign biliary strictures (N = 187) due to various etiologies received a FCSEMS with scheduled removal at 6–12 months and were followed for 5 years. We report here long-term outcomes of the subgroup of patients with PCBS (N = 18). Kaplan Meier analyses assessed long-term freedom from re-stenting. Adverse events were documented.ResultsEndoscopic removal of the FCSEMS was achieved in 83.3% (15/18) of patients after median indwell of 10.9 (range 0.9–13.8) months. In the remaining 3 patients (16.7%), the FCSEMS spontaneously migrated and passed without complications. At the end of FCSEMS indwell, 72% (13/18) of patients had stricture resolution. At 5 years after FCSEMS removal, 84.6% (95% CI 65.0–100.0%) of patients who had stricture resolution at FCSEMS removal remained stent-free. In addition, at 75 months after FCSEMS placement, the probability of remaining stent-free was 61.1% (95% CI 38.6–83.6%) for all patients. Stent or removal related serious adverse events occurred in 38.9% (7/18) all resolved without sequalae.ConclusionsIn patients with symptomatic PCBS, temporary placement of a single FCSEMS intended for 10–12 months indwell is associated with long-term stricture resolution up to 5 years. Temporary placement of a single FCSEMS may be considered for patients with PCBS not involving the main hepatic confluence.Trial registration numbersNCT01014390; CTRI/2012/12/003166; Registered 17 November 2009.
