Published: November 2019

AimThe aim of this study was to investigate if working in a cold environment and feeling cold at work are associated with chronic pain (ie, lasting ≥3 months).MethodsWe used data from the sixth survey (2007–2008) of the Tromsø Study. Analyses included 6533 men and women aged 30–67 years who were not retired, not receiving full-time disability benefits and had no missing values. Associations between working in a cold environment, feeling cold at work and self-reported chronic pain were examined with logistic regression adjusted for age, sex, education, body mass index, insomnia, physical activity at work, leisure time physical activity and smoking.Results779 participants reported working in a cold environment ≥25% of the time. This exposure was positively associated with pain at ≥3 sites (OR 1.57; 95% CI 1.23 to 2.01) and with neck, shoulder and leg pain, but not with pain at 1–2 sites. Feeling cold sometimes or often at work was associated with pain at ≥3 sites (OR 1.58; 95% CI 1.22 to 2.07 and OR 3.90; 95% CI 2.04 to 7.45, respectively). Feeling cold often at work was significantly and positively associated with pain at all sites except the hand, foot, stomach and head.ConclusionWorking in a cold environment was significantly associated with chronic pain. The observed association was strongest for pain at musculoskeletal sites and for those who often felt cold at work.

ObjectiveTo assess the effectiveness of tonsillectomy/adenotonsillectomy in reducing medical care visits for pharyngitis or tonsillitis in children and adults with chronic/recurrent tonsillitis.DesignRetrospective cohort study.SettingData were retrieved from the VEGA register, a comprehensive regional cohort in Sweden.Participants1044 children (<15 years) and 2244 adults.InterventionTonsillectomy/adenotonsillectomy compared with no surgical treatment.Main outcome measuresChanges in yearly mean rates of medical care visits due to pharyngitis/tonsillitis.ResultsIn children, there was a significant decrease in the yearly mean medical care visits rate from 1.93 (1.82 to 2.04) before surgery to 0.129 (0.099 to 0.165) after surgery, with a mean change of −1.80 (−1.90 to −1.69), p<0.0001. In patients who did not undergo surgery, the corresponding mean change was −1.51 (−1.61 to −1.41), resulting in a mean difference in the change in visit rates between the intervention and control groups of −0.283 (−0.436 to −0.135), p=0.0002. In adults, a significant decrease in the yearly mean medical care visit rate was observed from 1.45 (1.39 to 1.51) before surgery to 0.152 (0.132 to 0.173) after surgery, with a mean change of −1.30 (−1.36 to −1.24), p<0.0001, compared with −1.18 (−1.24 to −1.13) in the control group. The difference in the change in yearly mean visit rate between the surgical and non-surgical groups was −0.111 (−0.195 to −0.028), p=0.0097. The subgroup analysis showed a greater effect of surgery in children, in patients with a higher number of medical care visits before surgery and in the first year of follow-up.ConclusionIn this cohort of patients moderately or less affected with chronic/recurrent tonsillitis, the effectiveness of tonsillectomy/adenotonsillectomy in reducing medical care visits for pharyngitis and tonsillitis compared with no surgical treatment was low and of questionable clinical value.
Generalized phonon density of states of La2−xSrxCuO4cuprate superconductor
Authors: Gupta Anushri , Verma Sanjeev K. , Kumari Anita , Indu B. D. 
Published: November 2019

Many body quantum dynamics of phonons is steadily developed by considering the various effects of anharmonicities, defects (consider as doping or impurity concentration) and electron–phonon interactions in model Hamiltonian (instead of BCS Hamiltonian) for a high-temperature superconductor (HTS). This enables to obtain the expressions for the renormalized phonon spectrum, the renormalized phonon density of states (RPDOS). The RPDOS can be resolved into diagonal and nondiagonal parts where the nondiagonal component is found highly impurity-dependent. Considering the suitable Born–Mayer–Huggins (BMH) interaction potential, the renormalized phonon spectrum, RPDOS and generalized phonon density of states (GPDOS) of the La[Formula: see text]Sr[Formula: see text]CuO4layered superconductor have been numerically analyzed and it was found that these quantities depend on doping concentration, anharmonicities, and temperature. The results are compared with the inelastic neutron scattering experimental data of GPDOS for La[Formula: see text]Sr[Formula: see text]CuO4and are found in good agreement. The ratio of deviation in GPDOS to GPDOS at critical temperature ([Formula: see text] K) shows the implicit difference at [Formula: see text]. The impact of defects, anharmonicities, and electron–phonon interactions in the cuprate superconductors virtually modify the scenario of GPDOS and affirm a large number of exotic peaks in the spectrum.
Challenges for geological surveys deriving from global megatrends: The Federal Institute for Geosciences and Natural Resources of Germany's perspective and answers
Authors: Watzel Ralph 
Published: November 2019

Abstract
Global population growth, urbanization, increasing standards of living in many developing countries, climate change and reformation of (renewable) energy supply are among the most important trends of the twenty-first century, accompanied by a continuous need for conflict mitigation and peacekeeping as well as civil society's right to political participation. Goals for global sustainable development relate directly to the role and key expertise of geological surveys. The Federal Institute for Geosciences and Natural Resources of Germany (BGR) supports these goals by adapting its agenda and scientific skills to global needs under the paradigm of ‘sustainability, responsibility and safety’. Our understanding of sustainability is the balance between economy, ecology and societal needs. Here, we report on the results of the recent adaption process within the BGR, giving a forecast for the upcoming decade. From now on, we will screen socio-economic developments continuously and adapt our work to the needs in politics, economy and society based on our knowledge and experience acquired over the last decades.

Published: November 2019

Abstract
EuroGeoSurveys (EGS) is a not-for-profit organization representing 37 national geological surveys and some regional surveys; it has an overall workforce of several thousand experts. EGS members provide official, interoperable, homogeneous, reliable, INSPIRE (infrastructure for spatial information in the European Community)-compliant public data on the subsurface for the benefit of society in terms of circular economy development, sustainable management of the subsurface resources, understanding and combatting climate change and the development of infrastructures and mitigation of geology-related natural hazards. The EGS is committed to establishing a geological service for Europe based on three pillars: (1) joint research with impact on EU policy level, which is being implemented through the GeoERA programme (Establishing the European Geological Surveys Research Area to deliver a Geological Service for Europe); (2) harmonizing and sharing pan-European geological data, through the European Geological Data Infrastructure (EGDI); and (3) sharing knowledge, capacities and infrastructure, through the pan-African support to the EGS-Organization of African Geological Surveys (OAGS) Partnership (PanAfGeo project). The EGS will continue to support the EU in its transition to a low-carbon, climate-neutral, resource-efficient, socially and environmentally resilient economy, in full compliance with the United Nations 2030 Agenda and the 17 Sustainable Development Goals.
The Geological Survey of Finland strengthening its role as a key player in mineral raw materials innovation ecosystems
Authors: Nurmi Pekka A. 
Published: November 2019

Abstract
The Geological Survey of Finland (GTK) has over 130 years of history in mapping and studying mineral resources and their sustainable use. This has resulted in a globally top-ranking geodatabase and profound knowledge of Finnish geology and mineral resources, and has had a crucial impact on the continuously developing mining and exploration business in Finland. The basic mandate of the GTK has remained the same, but the strategic focus and mode of operation have changed considerably to meet new demands. Today, the GTK plays a vital role in providing geoscientific expertise and specialist services for a wide range of stakeholders and commercial clients in government, the business sector, academia and the wider community, in Finland and internationally. The GTK is actively building new ways to co-operate with universities, research organizations and companies to support future development and to expand its own expertise. This is further supported by the proactive use of cutting-edge technologies, such as the geomaterials research infrastructure, which allows studies from the nanoscale up to kilotons for diverse applications of mineral materials. The GTK plans to further strengthen its role as a key player in the minerals sector innovation ecosystems with a focus on primary minerals, the circular economy, digital solutions and water issues, which are expected to be essential factors for sustainable development through the 2020s and beyond. The GTK's main challenge is to ensure the continuous enhancement and renewal of expertise, to adapt and respond to future opportunities.
Pathogen-Boosted Adoptive Cell Transfer Therapy Induces Endogenous Antitumor Immunity through Antigen Spreading

Published: November 2019

Abstract
Loss of target antigens in tumor cells has become one of the major hurdles limiting the efficacy of adoptive cell therapy (ACT)–based immunotherapies. The optimal approach to overcome this challenge includes broadening the immune response from the initially targeted tumor-associated antigen (TAA) to other TAAs expressed in the tumor. To induce a more broadly targeted antitumor response, we utilized our previously developed Re-energized ACT (ReACT), which capitalizes on the synergistic effect of pathogen-based immunotherapy and ACT. In this study, we showed that ReACT induced a sufficient endogenous CD8+ T-cell response beyond the initial target to prevent the outgrowth of antigen loss variants in a B16-F10 melanoma model. Sequentially, selective depletion experiments revealed that Batf3-driven cDC1s were essential for the activation of endogenous tumor-specific CD8+ T cells. In ReACT-treated mice that eradicated tumors, we observed that endogenous CD8+ T cells differentiated into memory cells and facilitated the rejection of local and distal tumor rechallenge. By targeting one TAA with ReACT, we provided broader TAA coverage to counter antigen escape and generate a durable memory response against local relapse and metastasis.

Spontaneous Coronary Artery Dissection in Patients With a Provisional Diagnosis of Takotsubo Syndrome
Authors: Hausvater Anaïs , Smilowitz Nathaniel R. , Saw Jacqueline , Sherrid Mark , Ali Thara , Espinosa Dalisa , Mersha Rediet , DeFonte Maria , Reynolds Harmony R. 
Published: November 2019

Background
Takotsubo syndrome (TTS) mimics acute myocardial infarction in the absence of culprit coronary artery disease and is more common in women. Spontaneous coronary artery dissection (SCAD) shares a predilection for women, can result in left ventricular wall motion abnormalities similar to TTS, and may manifest subtle angiographic findings. The aim of this study was to determine the frequency of SCAD misdiagnosed as TTS.

Methods and Results
Coronary angiograms of patients presenting with a provisional diagnosis of TTS were retrospectively reviewed by an independent expert blinded to left ventriculography and the specific purpose of the study to assess for SCAD. TTS was defined using European Society for Cardiology criteria. SCAD was categorized according to the Saw angiographic classification. Among 80 women with a provisional diagnosis of TTS, 2 (2.5%) met angiographic criteria for definite SCAD. Both dissections were located in the distal left anterior descending coronary artery and classified as type 2b. The wall motion abnormality was apical in both cases. An additional 7 patients (9%) had angiography that was indeterminate for SCAD. Clinical characteristics of patients with and without SCAD were similar.

Conclusions
Among patients with a provisional diagnosis of TTS, definite SCAD in the left anterior descending coronary artery was present in 2.5% of cases, and coronary angiography was indeterminate for SCAD in an additional 9%. Careful review of coronary angiography may avoid missed diagnoses of SCAD in patients with myocardial infarction, nonobstructive coronary arteries, and wall motion abnormalities consistent with TTS. Intracoronary imaging maybe considered to establish a definitive diagnosis of SCAD when angiography is inconclusive.
Perceptions of Public and Nonpublic Reporting of Interventional Cardiology Outcomes and Its Impact on Practice: Insights From the Veterans Affairs Clinical Assessment, Reporting, and Tracking Program
Authors: Morrison Justin , Plomondon Mary E. , O'Donnell Colin I. , Giri Jay , Doll Jacob A. , Valle Javier A. , Waldo Stephen W. 
Published: November 2019

Background
Physicians have expressed significant mistrust with public reporting of interventional cardiology outcomes. Similar data are not available on alternative reporting structures, including nonpublic quality improvement programs with internally distributed measures of interventional quality. We thus sought to evaluate the perceptions of public and nonpublic reporting of interventional cardiology outcomes and its impact on clinical practice.

Methods and Results

A standardized survey was distributed to 218 interventional cardiologists in the Veterans Affairs Healthcare System, with responses received from 62 (28%). The majority of respondents (90%) expressed some or a great deal of trust in the analytic methods used to generate reports in a nonpublic quality improvement system within Veterans Affairs, while a minority (35%) expressed similar trust in the analytic methods in a public reporting system that operates outside Veterans Affairs (
P
<0.001). Similarly, a minority of respondents (44%) felt that in‐hospital and 30‐day mortality accurately reflected interventional quality in a nonpublic quality improvement system, though a smaller proportion of survey participants (15%) felt that the same outcome reflected procedural quality in public reporting systems (
P
<0.001). Despite these sentiments, the majority of operators did not feel pressured to avoid (82% and 75%;
P
=0.383) or perform (72% and 63%;
P
=0.096) high‐risk procedures within or outside Veterans Affairs.

Conclusions
Interventional cardiologists express greater trust in analytic methods and clinical outcomes reported in a nonpublic quality improvement program than external public reporting environments. The majority of physicians did not feel pressured to avoid or perform high‐risk procedures, which may improve access to interventional care among high‐risk patients.

<strong>Checklist of the caddisflies of the Iberian Peninsula and Balearic Islands (Trichoptera)</strong>
Authors: GONZÁLEZ MARCOS A. , MARTÍNEZ JESÚS 
Published: November 2019

The first faunistic review of the caddisflies (Trichoptera) from the Iberian Peninsula, using as a reference the Limnofauna Europaea, was presented in 1987 and included 267 species. A comprehensive faunistic, nomenclatorial and systematically revised checklist of the Iberian caddsiflies was given in 1992 and included 294 species for the Iberian Peninsula and Balearic Islands. Since 1992 our knowledge of the faunistic composition of some peninsular areas, especially of the meridional half and the Mediterranean region have considerably improved. It is now possible to update significantly the knowledge of caddisflies in the Iberian Peninsula and Balearic Islands. We critically reviewed the literature data and supplemented these with our recent new records. We also take into consideration some unpublished collections of the authors from different Iberian regions. The checklist now contains 342 species (327, 185, 60 and 18 species from the Spanish mainland, the Portuguese mainland, Andorra, and the Balearic Islands, respectively), belonging to 75 genera and 22 families. Together, 4 families, i.e., Limnephilidae (23.7%), Hydroptilidae (14.9%), Leptoceridae (10.5%) and Rhyacophilidae (9.3 %), comprise 57% of the Iberian fauna.
<strong>Photography of Trichoptera in flight</strong>
Authors: McIlleron W. Geoff , De Moor Ferdinand C. 
Published: November 2019

Whereas photography of insects at rest is used for a wide variety of purposes, including illustrating publications and aiding their identification, photography of insects in flight is more challenging and little practiced. This paper describes a system that uses a digital single-lens-reflex camera combined with commercial-level flashes (with electronic power settings to give very short exposures) and simple electronics in a rig that can be used to capture high quality images of night-flying insects. With such a rig, hundreds of images of free flying Trichoptera have been obtained. Preliminary observations of night-flying Athripsodes bergensis (Leptoceridae) indicate that this system could be used for studying the mechanics of flight, wing beat frequency, aerodynamics, flying speed, aerial activity, and behavioural ecology of night-flying insects in their natural environment. This paper briefly describes the technique as applied at a site on the banks of the Groot River in the southern Cape region of South Africa between October 2008 and April 2009 and presents a selection of the images obtained.
Do All Hospital Systems Have Market Power? Association Between Hospital System Types and Cardiac Surgery Prices
Authors: Choi Sung W. , Dor Avi 
Published: November 2019

Objective: This study explores the price implications of hospital systems by analyzing the association of system characteristics with selected cardiac surgery pricing. Data Source: Using a large private insurance claim database, the authors identified 11 282 coronary artery bypass graft (CABG) cases and 49 866 percutaneous coronary intervention (PCI) cases from 2002 to 2007. Study Design: We conducted a retrospective observational study using generalized linear models. Principal Findings: We found that the CABG and PCI prices in centralized health and physician insurance systems were significantly lower than the prices in stand-alone hospitals by 4.4% and 6.4%, respectively. In addition, the CABG and PCI prices in independent health systems were significantly lower than in stand-alone hospitals, by 15.4% and 14.5%, respectively. Conclusion: The current antitrust guidelines tend to focus on the market share of merging parties and pay less attention to the characteristics of merging parties. The results of this study suggest that antitrust analysis could be more effective by considering characteristics of hospital systems.
Synthesis of natural zeolite agglomerates: clinoptilolite-based geopolymers through aluminate activation

Published: November 2019

AbstractNatural zeolite (clinoptilolite)-based geopolymers were synthesized using alkali aluminate solution, including aluminate anodizing waste solution. The effect of calcination of the clinoptilolite sample at 900°C was investigated. The samples were studied by powder X-ray diffraction, thermal analysis, scanning electron microscopy and N2-specific surface area. The alkali aluminate-activated clinoptilolite geopolymers are characterized by satisfactory compressive strength (up to 37 MPa), low density and acceptable shrinkage. The clinoptilolite geopolymer obtained contains an X-ray amorphous phase and newly formed phillipsite and zeolite NaP. The presence of zeolite phases in the geopolymer agglomerate could be beneficial in products with specific qualities and properties, such as ion exchange, passive cooling, antimicrobial activity,etc.
