Enteral Ciprofloxacin or Levofloxacin for Ventilator-Associated Tracheobronchitis in Children
Authors: Smith Christina , Sierra Caroline , Robbins Joanna , Cobbina Ekua
Published: June 2021

Introduction Pseudomonas aeruginosa is the most commonly isolated
organism in children with ventilator-associated tracheobronchitis (VAT).
Enteral treatment with ciprofloxacin or levofloxacin is sometimes
employed, but supportive data are limited. The purpose of this study was
to evaluate the effectiveness and safety of enteral ciprofloxacin and
levofloxacin administration for VAT in children. Methods This was a
retrospective review of electronic medical records for children less
than 18 years of age who received enteral ciprofloxacin or levofloxacin
for the treatment of VAT from January 2013 through January 2020 at an
academic children’s hospital. Results Seventy-six children (median age
9.5, IQR 3.6-13.1 years), received ciprofloxacin or levofloxacin for VAT
treatment during the study period. Median treatment duration was 8
(range 7-10) days. Most tracheostomy cultures (n=70/82, 85%) were
polymicrobial, with P. aeruginosa most commonly isolated (n=67/224
organisms, 30%). Sixty-five children (86%) were successfully treated
with an enteral fluoroquinolone. Antibiotics were changed or extended
for two (3%) children. Ten (13%) children were prescribed antibiotics
and eight (11%) required hospitalization for a lower respiratory tract
infection within 30 days of completion of their fluoroquinolone course.
Six (8%) patients received a seizure rescue medication, seven (9%)
experienced emesis, and one (1%) had elevated transaminases.
Tendonitis, tendon rupture and QTc prolongation were not observed.
Conclusions The results of this study suggest enteral fluoroquinolones
may be effective for the treatment of VAT in children. Further study is
warranted to clarify the role of these agents in pediatric VAT.

Published: June 2021

Background: While many risk models have been developed to predict
prognosis in heart failure (HF), these models are rarely useful for the
clinical practitioner as they include multiple variables that might be
time-consuming to obtain, they are usually difficult to calculate and
they may suffer from statistical overfitting. Present study aimed to
investigate whether a simpler model, namely ACEF-MDRD score, could be
used for predicting one-year mortality in HF patients. Methods: 748
cases within the SELFIE-HF registry had complete data to calculate
ACEF-MDRD score. Patients were grouped into tertiles for analyses.
Results: Significantly more patients within the ACEF-MDRDhigh tertile
(30.0%) died within one year, as compared to other tertiles (10.8% and
16.1%, respectively, for ACEF-MDRDlow and ACEF-MDRDmed,
p<0.001 for both comparisons). There was a stepwise decrease
in one-year survival as ACEF-MDRD score increased (log-rank
p<0.001). ACEF-MDRD was an independent predictor of survival
after adjusting for other variables (OR: 1.14, 95%CI:1.04 – 1.24,
p=0.006). ACEF-MDRD score offered similar accuracy to GWTG-HF score for
prediction of one-year mortality (p=0.14). Conclusions: ACEF-MDRD is a
predictor of mortality in patients with HF, and its usefulness is
comparable to similar yet more complicated models.
Kin discrimination in allelopathy and consequences for agriculture
Authors: Anten Niels , Chen Bin
Published: June 2021

Recent research has shown that plants can distinguish
genetically-related individuals from strangers (kin recognition) and
exhibit more cooperative behaviours towards these more related
individuals (kin discrimination). The first evidence for this was found
when Cakile edentula plants growing with half-sibs allocated relatively
less biomass to roots than plants growing with unrelated individuals,
indicating that kin recognition can reduce the intensity of competition
(Dudley & File, 2007). Since then, kin discrimination has been shown to
result in reduced competition for soil resources (Semchenko, Saar, &
Lepik, 2014), light (Crepy & Casal, 2015) and pollinators (Torices,
Gómez, & Pannell, 2018). On the other hand, allelopathy, plants
producing chemical compounds that negatively affect performance of
neighbour plants, has also been widely documented (Inderjit & Duke,
2003) and shown to profoundly affect local species coexistence and plant
community structure (Meiners, Kong, Ladwig, Pisula, & Lang, 2012). In
crops allelopathy can also be beneficial in suppressing weeds (Macías,
Mejías, & Molinillo, 2019). In the current issue, Xu, Cheng, Kong, and
Meiners (2021) published the first study to show that kin discrimination
can also affect the balance between direct competition for resources and
allelopathy, and this together may lead to improved weed suppression in
rice.
SimAndro-plus: On computing similarity of android applications
Authors: Hamedani Masoud , Kim Sang-Wook
Published: June 2021

In this paper, we propose SimAndro-Plus as an improved variant of the state-of-the-art method, SimAndro, to compute the similarity of Android applications (apps) regarding their functionalities. SimAndro-Plus has two major differences with SimAndro: 1) it exploits two beneficial features to similarity computation, which are totally disregarded by SimAndro; 2) to compute the similarity score of an app-pair based on strings and package name features, SimAndro-Plus considers not only those terms co-appearing in both apps but also considers those terms appearing in one app while missing in the other one. The results of our extensive experiments with three real-world datasets and a dataset constructed by human experts demonstrate that 1) each of the two aforementioned differences is really effective to achieve better accuracy and 2) SimAndro-Plus outperforms SimAndro in similarity computation by 14% in average.

Objective.

To assess
whether risk of severe outcomes among patients with type 1 diabetes (T1DM)
hospitalized for COVID-19 differs from patients without diabetes (DM) or with type
2 diabetes (T2DM).

Research Design and Methods.

Using the Premier
Healthcare Special COVID-19 Release Database records of patients discharged after
COVID-19 hospitalization from US hospitals from March to November 2020 (N=269,674, after exclusion),
we estimated risk differences (RD) and risk ratios (RR) of intensive care unit
admission or invasive mechanical ventilation (ICU/MV) and of death
among patients with T1DM compared with patients without DM or with T2DM.
Logistic models were adjusted for age, sex, and race or ethnicity. Models
adjusted for additional demographic and clinical characteristics were used to
examine whether other factors account for the associations between T1DM and
severe COVID-19 outcomes.

Results.

Compared with patients
without DM, T1DM was associated with a 21% higher absolute risk of ICU/MV (RD =
0.21, 95% Confidence Interval [CI]=0.19–0.24; RR=1.49, 95% CI=1.43–1.56) and a 5%
higher absolute risk of mortality (RD=0.05, 95% CI=0.03–0.07; RR=1.40, 95%
CI=1.24–1.57), adjusting for age, sex, and race or ethnicity. Compared with
patients with T2DM, T1DM was associated with a 9% higher absolute risk of
ICU/MV (RD=0.09, 95% CI=0.07–0.12; RR=1.17, 95% CI=1.12–1.22), but no
difference in mortality (RD=0.00, 95% CI=-0.02–0.02; RR=1.00, 95% CI=0.89–1.13).
After adjustment for diabetic ketoacidosis (DKA) occurring before or at
COVID-19 diagnosis, patients with T1DM no longer had increased risk of ICU/MV
(RD=0.01, 95% CI=-0.01–0.03) and had lower mortality (RD=-0.03, 95% CI=-0.05–
-0.01) compared to patients with T2DM.

Conclusions.

Patients with T1DM
hospitalized for COVID-19 are at higher risk for severe outcomes than those
without DM. Higher ICU/MV risk compared with patients with T2DM was largely
accounted for by the presence of DKA. These findings might further guide
recommendations related to DM management and the prevention of COVID-19.

Introduction: High energy consumption by buildings is a great threat to the environment and one of the major causes of climate change. With a population of 1.4 billion people and one of the fastest-growing economies in the world, India is extremely vital for the future of global energy markets. The energy demand for construction activities continues to rise and it is responsible for over one-third of global final energy consumption. Currently, buildings in India account for 35% of total energy consumption and the value is growing by 8% annually. Around 11% of total energy consumption are attributed to the commercial sector. Energy-efficient retrofitting of the built environments created in recent decades is a pressing urban challenge. Presently, most energy-efficient retrofit projects focus mainly on the engineering aspects. In this paper, we evaluate various retrofitting options, such as passive architectural interventions, active technological interventions, or a combination of both, to create the optimum result for the selected building. Methods: Based on a literature study and case examples, we identified various energy-efficient retrofit measures, and then examined and evaluated those as applied to the case study of Awas Bhawan (Rajasthan Housing Board Headquarters), Jaipur, India. For the evaluation, we developed a simulation model using EQuest for each energy measure and calculated the resultant energy savings. Then, based on the cost of implementation and the cost of energy saved, we calculated the payback period. Finally, an optimum retrofit solution was formulated with account for the payback period and ease of installation. Results and discussion: The detailed analysis of various energy-efficient retrofit measures as applied to the case study indicates that the most feasible options for retrofit resulting in optimum energy savings with short payback periods include passive architecture measures and equipment upgrades.
PROBLEM OF THE ANISOTROPY OF ELASTICITY AND STRENGTH IN ANISOTROPIC FIBER MATERIALS
Authors:   Saint Petersburg State University of Architecture and Civil Engineering, Glukhikh Vladimir
Published: June 2021

Introduction: The paper presents new results of studies on the anisotropy of fiber materials with cylindrical anisotropy, which include filament-wound composite materials reinforced with various fibers. Methods: We suggest a mathematical solution to a fourth-order partial differential equation in polar coordinates with two variables for an orthotropic anisotropic body. To solve this equation, we converted it into Cartesian coordinates and presented the stress function as a sum of polynomials. Results and Discussion: As a result of the solution, we obtained two relationships between the elastic constants in the principal directions of anisotropy (so-called elasticity parameters). One of them was obtained for the first time, and the other results from the solution of the anisotropy problem for an orthotropic curved body, suggested by S. G. Lekhnitsky. The obtained solution does not contradict Lekhnitsky’s solution. Thus, in our opinion, orthotropic materials can be divided into two groups. In one group, when shifting from the radial to the tangential direction, the elastic constants take on extreme values when the layers are at angles of 0, 60, and 90°. In the other group, there is no intermediate extreme value and the elastic constants take on extreme values when the layers are at angles of 0 and 90°. The obtained results can be applied in the development of new high-strength composite materials and new technologies for the design and manufacture of building structures, as well as in the design of high-strength structures from synthetic composite materials.
INVESTIGATING THE CORROSION INITIATION PROCESS IN REINFORCED CONCRETE STRUCTURES UNDER THE IMPACT OF CLIMATE CHANGE

Published: June 2021

Introduction: Climate change (temperature rise and sea level rise) has a considerable influence on the behavior of concrete structures over time. All concrete degradation processes are connected to climate variables and the effects of climate change. The RCP8.5 (Representative Concentration Pathway) scenario, which is part of the report on climate change and level rise scenarios for Vietnam, predicts that the beginning of the 21st century will see an average annual increase in temperature between 0.8 and 1.1°C. In the mid-21st century, the temperature will likely increase by 1.8–2.3°C, with the temperature in the north likely increasing by 2.0–2.3°C and in the south by 1.8–1.9°C. In marine environments, the degradation of concrete structures can occur rapidly due to chloride-induced reinforcement corrosion. Furthermore, sea level rise is going to reduce the distance from the coastline to the structures and lead to increased surface chloride concentration. Methods: The evaluation of chloride penetration was based on the ASTM C1202 test (ASTM, 2012). The cylinder specimens (d = 100 mm, h = 200 mm) used for a rapid chloride penetration test (RCPT) were immersed in water for 28 days in a water-curing tank. Results: This study proposes a predictive model for analyzing the impact of climate change on the service life of concrete structures on Vietnam’s North Central Coast. The corrosion initiation time decreases by 16.5% when the effects of both temperature rise and sea level rise are taken into consideration. When only temperature rise is taken into consideration, the rate of reduction is approximately 9.0%. These results reaffirm that climate change has a significant effect on the corrosion initiation time of concrete structures located in a marine environment.

Introduction: During experimental studies of structural steels responsible for the reliability of metal structures used, for example, in hoisting and transporting machinery, we established a correlation between the magnetic parameter Hp and characteristic changes in the metal microstructure during thermal cycling. It is shown that the Нр parameter depends on the initial structural state of steel, the amount and mass fraction of alloying elements, and the number of heating/cooling cycles. Methods: We found that an increase in the number of heating/cooling cycles and the amount of alloying elements, as well as preliminary cold plastic deformation with stage-by-stage control of structural changes using passive magnetic flux leakage testing results in a finer-grained structure, which was confirmed by metallographic analysis. Results: The paper considers specifics of structural changes in steels with different initial structures during thermal cycling. It is shown that the final grain size depends on the number of treatment cycles, the amount of alloying elements, and the initial microstructure. It is the fine-grain structure that improves the most important performance characteristics of steels: strength, cyclic strength, and cold brittleness.
