Authors: Souza Hadamo Fernandes de , Costa Jonatas Maia da 
Published: September 2020

O artigo aborda uma intervenção pedagógica com estudantes que eram punidos com a exclusão das aulas de Educação Física por apresentarem mau comportamento na escola. Procuramos experimentar o modelo Sport Education no enfrentamento à indisciplina em uma escola da rede pública. A pesquisa objetivava identificar e compreender possíveis mudanças atitudinais em estudantes tidos como indisciplinados. O estudo teve na pesquisa-ação seus princípios metodológicos e o grupo focal e questionário como instrumentos de produção de dados. O Sport Education carrega potencial de apropriação crítica da cultura corporal. O trabalho coletivo pode ser uma estratégia pedagógica alternativa na melhoria de comportamento dos estudantes caso a mediação se realize em compasso ao recrudescimento das relações afetivas entre professores e estudantes. A indisciplina permanece tema complexo e desafia os educadores. Entretanto, é fundamental superar o problema da exclusão normativa das aulas de Educação Física por ocasião da indisciplina.

Abstract. Previous observational evidence and numerical simulations have revealed that the surface sensible heating in spring (March–April–May, MAM) over
the Tibetan Plateau (TPSH) can affect the Asian regional hydrological cycle, surface energy balance, and climate through altering atmospheric heat
source of the Tibetan Plateau (TP). This study aims to investigate the impacts of MAM TPSH on the interannual variability of East Asian dust cycle
by using CAM4-BAM (version 4 of the Community Atmosphere Model coupled to a bulk aerosol model), MERRA-2 (version 2 of the Modern-Era
Retrospective analysis for Research and Applications) surface dust concentration, and TPSH measurements. Our simulations show that the surface dust
concentrations over the East Asian (EA) dust source region and over the northwestern Pacific (NP) in MAM are significantly positively correlated
with TPSH, with regionally averaged correlation coefficients of 0.49 for EA and 0.44 for NP. Similar positive correlations are also shown between
the MAM TPSH measurements averaged over the 73 observation sites and the surface dust concentration from MERRA-2. Simulation-based comparisons
between strongest and weakest TPSH years reveal that, the MAM surface dust concentration in the strongest TPSH years increases with relative
differences of 13.1 % over EA and 36.9 % over NP. These corresponding differences are found in MERRA-2 with 22.9 % and 13.3 % over
EA and NP, respectively. Further simulated results show that the processes of whole dust cycles (e.g., dust loading, emission, and transport, as
well as dust deposition) are also significantly enhanced during the strongest TPSH years over EA and NP. Through enhancing the TP heat source,
stronger TPSH in MAM generates an anticyclonic anomaly in middle and upper troposphere over the TP and over the downstream Pacific region,
respectively. These atmospheric circulation anomalies induced by the increased TPSH result in increasing the westerly winds over both EA and NP,
which in turn increases dust emissions over the dust source, and dust transport over these two regions, as well as the regional dust cycles. These
results suggest that addressing the East Asian dust changes in the future climates requires considering not only increasing greenhouse gas emissions
but also the variations of the TP's heat source under global warming.
Intra-annual variations of spectrally resolved gravity wave activity in the upper mesosphere/lower thermosphere (UMLT) region

Published: September 2020

Abstract. The period range between 6 and 480 min is known to represent
the major part of the gravity wave spectrum driving mesospheric dynamics. We
present a method using wavelet analysis to calculate gravity wave activity
with a high period resolution and apply it to temperature data acquired with
the OH* airglow spectrometers called GRIPS (GRound-based Infrared P-branch
Spectrometer) within the framework of the NDMC (Network for the Detection of
Mesospheric Change; https://ndmc.dlr.de, last access: 22 September 2020). We analyse data measured at the
NDMC sites Abastumani in Georgia (ABA; 41.75∘ N,
42.82∘ E), ALOMAR (Arctic Lidar Observatory for Middle Atmosphere Research) in Norway (ALR; 69.28∘ N,
16.01∘ E), Neumayer Station III in the Antarctic (NEU;
70.67∘ S, 8.27∘ W), Observatoire de Haute-Provence in France (OHP;
43.93∘ N, 5.71∘ E), Oberpfaffenhofen in Germany (OPN;
48.09∘ N, 11.28∘ E), Sonnblick in Austria (SBO;
47.05∘ N, 12.95∘ E), Tel Aviv in Israel (TAV;
32.11∘ N, 34.80∘ E), and the Environmental Research
Station Schneefernerhaus on top of Zugspitze mountain in Germany (UFS;
47.42∘ N, 10.98∘ E). All eight instruments are
identical in construction and deliver consistent and comparable data sets. For periods shorter than 60 min, gravity wave activity is found to be
relatively low and hardly shows any seasonal variability on the timescale
of months. We find a semi-annual cycle with maxima during winter and summer
for gravity waves with periods longer than 60 min, which gradually develops
into an annual cycle with a winter maximum for longer periods. The
transition from a semi-annual pattern to a primarily annual pattern starts
around a gravity wave period of 200 min. Although there are indications of
enhanced gravity wave sources above mountainous terrain, the overall pattern
of gravity wave activity does not differ significantly for the
abovementioned observation sites. Thus, large-scale mechanisms such as
stratospheric wind filtering seem to dominate the evolution of mesospheric
gravity wave activity.
Land-use perturbations in ley grassland decouple the degradation of ancient soil organic matter from the storage of newly derived carbon inputs

Published: September 2020

Abstract. In a context of global change, soil has been identified
as a potential carbon (C) sink, depending on land-use strategies. To detect
the trends in carbon stocks after the implementation of new agricultural
practices, early indicators, which can highlight changes in short timescales, are required. This study proposes the combined use of stable isotope probing and
chemometrics applied to solid-state 13C nuclear magnetic resonance (NMR) spectra to unveil the
dynamics of the storage and mineralization of soil carbon (C) pools. We focused on light
organic matter fractions isolated by density fractionation of soil water
stable aggregates because they respond faster to changes in land use than
the total soil organic matter (SOM). Samples were collected from an agricultural field experiment with grassland, continuous maize cropping, and ley grassland under temperate climate conditions. Our results indicated contrasting aggregate dynamics depending on land-use
systems. Under our experimental conditions, grassland returns larger amounts of C as belowground inputs than maize cropping, evidencing a different distribution of light C fractions between aggregate classes. Coarse aboveground inputs from maize contributed mostly to larger
macroaggregates. Land-use changes with the introduction of ley grassland
provoked a decoupling of the storage and/or degradation processes after the
grassland phase. The newly derived maize inputs were barely degraded during
the first 3 years of maize cropping, whereas grassland-derived material
was depleted. As a whole, results suggest large microbial proliferation as
shown by 13C NMR under permanent grassland, then reduced within the
first years after the land-use conversion, and finally restored. The study
highlighted a fractal structure of the soil, determining a scattered spatial distribution of the cycles of storage and degradation of soil organic matter related to detritusphere dynamics. As a consequence, vegetal inputs from a new land use are creating new detritusphere microenvironments that may be disconnected from the dynamics of C cycle of the previous land use. The formation of those different and unconnected microenvironments may explain the observed legacy effect of the previous land use, since each
microenvironment type contributes separately to the overall soil C cycle.
The effects of the new land use on the soil C cycle are delayed until the
different detritusphere microenvironments remain unconnected, and the ones
from the previous land use represent the predominant microenvironment type.
Increasing knowledge of the soil C dynamics at a fine scale will be
helpful in refining the prediction models and land-use policies.
A Lagrangian analysis of the dynamical and thermodynamic drivers of large-scale Greenland melt events during 1979–2017
Authors: Hermann Mauro , Papritz Lukas , Wernli Heini 
Published: September 2020

Abstract. In this study, we systematically investigate the dynamical and thermodynamic processes that lead to 77 large-scale melt events affecting high-elevation regions of the Greenland Ice Sheet (GrIS) in June–August (JJA) 1979–2017. For that purpose, we compute 8 d kinematic backward trajectories from the lowermost ∼500 m above the GrIS during these events. The key synoptic feature accompanying the melt events is an upper-tropospheric ridge southeast of the GrIS associated with a surface high-pressure system. This circulation pattern is favorable to induce rapid poleward transport (up to 40∘ latitude) of warm (∼15 K warmer than climatological air masses arriving on the GrIS) and moist air masses from the lower troposphere to the western GrIS and subsequently to distribute them in the anticyclonic flow over north and east Greenland. During transport to the GrIS, the melt event air masses cool by ∼15 K due to ascent and radiation, which keeps them just above the critical threshold to induce melting. The thermodynamic analyses reveal that the final warm anomaly of the air masses is primarily owed to anomalous horizontal transport from a climatologically warm region of origin. However, before being transported to the GrIS, i.e., in their region of origin, these air masses were not anomalously warm. Latent heating from condensation of water vapor, occurring as the airstreams are forced to ascend orographically or dynamically, is of secondary importance. These characteristics were particularly pronounced during the most extensive melt event in early July 2012, where, importantly, the warm anomaly was not preserved from anomalously warm source regions such as North America experiencing a record heat wave. The mechanisms identified here are in contrast to melt events in the low-elevation high Arctic and to midlatitude heat waves, where adiabatic warming by large-scale subsidence is essential. Considering the impact of moisture on the surface energy balance, we find that radiative effects are closely linked to the air mass trajectories and enhance melt over the entire GrIS accumulation zone due to (i) enhanced downward longwave radiation related to poleward moisture transport and a shift in the cloud phase from ice to liquid primarily west of the ice divide and (ii) increased shortwave radiation in clear-sky regions east of the ice divide. Given the ongoing increase in the frequency and the melt extent of large-scale melt events, the understanding of upper-tropospheric ridges over the North Atlantic, i.e., also Greenland blocking, and its representation in climate models is crucial in determining future GrIS accumulation zone melt and thus global sea level rise.

Published: September 2020

Introduction:
Several studies have found the negative impact of alcohol use disorder (AUD), most notably coagulation derangements. We sought to investigate the effects of AUD after primary total knee arthroplasty (TKA) for (1) postoperative complications, (2) lengths of stay, and (3) costs of care.

Methods:
This was a retrospective database analysis of Medicare patients with AUD undergoing primary TKA performed between 2005 and 2014. Patients with AUD were matched to controls in a 1:5 ratio by age, sex, and medical comorbidities. The query yielded 354,690 TKA patients: 59,126 with AUD and 295,564 without AUD.

Results:
Patients with AUD had significantly greater odds ratio (OR) of medical complications, including venous thromboembolism (VTE) within 90 days (OR: 1.41, P < 0.0001) and at 1 year (OR: 1.51, P < 0.0001) and greater 2-year implant-related complications after primary TKA. Furthermore, patients with AUD had significantly longer lengths of stay (4 versus 3 days, P < 0.0001) and incurred a significantly higher episode of care costs ($15,569.76 versus $13,763.06, P < 0.0001).

Discussion:
The present study demonstrated a significant association between AUD and the development of VTE. We hope this research will aid in risk stratification and tailoring of VTE chemoprophylaxis and postoperative management in this at-risk group after TKA.

Published: September 2020

Introduction: Patients with renal cell carcinoma (RCC) with level 3 or 4 caval thrombus have a poor prognosis, with reported five-year survival rates of 30–40%. The aim of this study was to assess the perioperative morbidity and long-term oncological outcomes for radical nephrectomy with resection of vena cava thrombus using a combined surgical approach, including extracorporeal circulation and deep hypothermic circulatory arrest.
Methods: A retrospective review was performed of the institutional case log to identify all radical nephrectomies with caval thrombus performed from January 2006 to May 2020.
Results: Twenty-five patients were identified with level 2 thrombus in one (4%), level 3 thrombus in eight (32%), and level 4 in 16 (64%). The median followup was 20.6 months (range 0.2–133.3). The median age at surgery was 68.4 years (range 44.2–85.5). Twenty-one (84%) patients were symptomatic at presentation. Six (24%) patients had distant metastases at diagnosis. The median circulatory arrest time was 15 minutes (range 6–35). The 30-day grade ≥3 complication rate was 8%. The 30-day mortality rate was 8%. The one-year, two-year, three-year, and five-year recurrence-free survival (RFS) rates were 53%, 18%, 10%, and 10%, respectively. The median time to systemic treatment was 7.7 months (range 1.2–25.7). The one-year, two-year, three-year, five-year overall survival (OS) rates were 70%, 43%, 36%, and 31%, respectively.
Conclusions: Radical nephrectomy with resection of vena cava thrombus using extracorporeal circulation and deep hypothermic circulatory arrest is associated with some morbidity and mortality but remains a safe and effective strategy for advanced RCC patients who would otherwise be managed palliatively.
De ‘strijd om kerken’

The ‘struggle for churches’. A Public Administration sketch of a (religious and policy) sensitive subject
While many new churches were built in the Netherlands sixty years ago to meet the demands of religious communities for space for their worship, the situation in 2020 is completely different. It is true that a church is sometimes built here and there in the Netherlands, but the general picture is that many churches have been withdrawn as places of worship in recent years, that a number have been demolished and that many have been given a new designated purpose. The fate of a church building often evokes many emotions in people. For example, we experienced this when we, together with the Parisians, watched in disbelief as fire destroyed parts of Notre Dame. This is related to the fact that for many people churches are more than just ‘beautifully stacked stones’. They are directly linked to the highs and lows of people’s individual and collective lives. People were baptized and married in that church, funeral services of loved ones were held there and the church is still a familiar part of the image of city or village. Rightly so that churches are also seen as ‘affective monuments’. The central question, however, is how to deal with religious heritage (policy related) now that churches are emptying? In this article the authors first give a brief outline of the background, nature and scope of what they call the ‘church problem’. Then they discuss the ‘battle for churches’ associated with this problem, which they subsequently try to interpret from a number of Public Administration theories. The role of certain individuals and organizations in the ‘battle for churches’, the so-called ‘entrepreneurs’, is further explored. They pay specific attention to the role of the municipality in this as a whole and call on all parties involved to deal (politically) with the ‘church problem’ rather than ‘spasmodically’.
Neutraliteitsvraagstukken naar aanleiding van de leegloop van kerken
Authors: Vleugel Jos 
Published: September 2020

Neutrality issues due to the emptying of churches
The author of this contribution asks whether and, if so, in which specific cases, the principle of the separation of church and state applies to situations related to the emptying of churches. As a result of the closure, restoration and re-designation of church buildings, governments may be confronted with issues that touch on this principle. The principle of the separation between church and state prescribes that the government must be neutral. This contribution explains that this neutral attitude differs according to the social domain in which the issue arises. Using a contextual approach, he makes clear which interests (religious, general, private and the interests of others) should be decisive in government policy in this area in the various domains.

Three ‘entrepreneurs’ have their say
In this contribution, three entrepreneurs indicate how they are actively involved in the processes of re-designation of churches. Based on a number of tools, they try to offer prospects for the future of churches in close consultation with the parties involved. This is by no means easy and requires strategic, tactical and open action to bridge existing contradictions and guarantee a future for the religious heritage.

Published: September 2020

OBJECTIVEEvidence is limited about important maternal and neonatal risk factors that affect neonatal renal function. The incidence of acute kidney injury (AKI) and identification of associated risk factors in neonates exposed to antenatal indomethacin was studied.METHODSA retrospective cohort of neonates exposed to antenatal indomethacin within 1 week of delivery was analyzed for development of AKI up to 15 days of life. Adjusted hazard ratios (HRs) and 95% CIs for AKI risk were calculated in time-dependent Cox proportional hazards models.RESULTSAmong 143 neonates with mean gestational age of 28.3 ± 2.4 weeks, AKI occurred in 62 (43.3%), lasting a median duration of 144 hours (IQR, 72–216 hours). Neonates with AKI had greater exposure to postnatal NSAIDs (48.4% vs 9.9%, p &lt; 0.001) and inotropes (37.1% vs 3.7%, p &lt; 0.001) compared with neonates without AKI. In multivariable-adjusted models, increased AKI risk was observed with antenatal indomethacin doses received within 24 to 48 hours (HR, 1.6; 95% CI, 1.28–1.94; p = 0.036) and &lt;24 hours (HR, 2.33; 95% CI, 1.17–4.64; p = 0.016) prior to delivery. Further, postnatal NSAIDs (HR, 2.8; 95% CI, 1.03–7.61; p = 0.044), patent ductus arteriosus (HR, 4.04; 95% CI, 1.27–12.89; p = 0.018), and bloodstream infection (HR, 3.01; 95% CI, 1.37–6.60; p = 0.006) were associated significantly with increased risk of AKI following antenatal indomethacin. Neonates with AKI experienced more bloodstream infection, severe intraventricular hemorrhage, patent ductus arteriosus, respiratory distress syndrome, and longer hospitalization.CONCLUSIONSExtended risk of AKI with antenatal indomethacin deserves clinical attention among this population at an already increased AKI risk.
Levofloxacin for Antibacterial Prophylaxis in Pediatric Patients With Acute Myeloid Leukemia or Undergoing Hematopoietic Stem Cell Transplantation
Authors: Patel Bianka , Noda Andrew , Godbout Emily , Stevens Michael , Noda Cady 
Published: September 2020

OBJECTIVE
This study aimed to evaluate the use of levofloxacin for the prevention of bacterial infections in pediatric patients with acute myeloid leukemia or those undergoing hematopoietic stem cell transplantation.

METHODS
This study was a single-center, retrospective review designed to assess the frequency of bacteremia with levofloxacin prophylaxis compared with historical controls that used other, clinician-directed antibacterial prophylaxis. The primary outcome of the study was microbiologically documented bacteremia. Secondary outcomes included febrile neutropenia, clinically documented infection, duration of neutropenia, treatment antibiotic exposure days, Clostridioides difficile infection, and infection-related mortality.

RESULTS
Of the 60 patients included, 24 patients with 32 hospital admissions received levofloxacin and 36 patients with 48 hospital admissions received clinician-directed prophylaxis. There was no difference found in the frequency of bacteremia between levofloxacin and clinician-directed prophylaxis (15.6% vs 10.4%, p = 0.49). There was no difference in the incidence of febrile neutropenia, clinically documented infection, treatment antibiotic exposure days, or 30-day infection-related mortality between the 2 groups. The levofloxacin group had a longer mean duration of neutropenia compared with clinician-directed prophylaxis (26.8 days vs 16.4 days, p = 0.01).

CONCLUSIONS
There was no difference in bacteremia between levofloxacin prophylaxis and clinician-directed prophylaxis in pediatric patients with acute myeloid leukemia or those undergoing hematopoietic stem cell transplantation. Levofloxacin prophylaxis is an appropriate alternative for the prevention of serious bacterial infections in this patient population, although further studies are needed to confirm these results.
