The Optimizing Background Infusion Mode Decreases Intravenous Patient-Controlled Analgesic Volume Compared to Fixed-Rate Background Infusion in Patients Undergoing Laparoscopic Cholecystectomy: A Prospective, Randomized, Controlled, Double-Blind Study

Background and objectives: Traditional intravenous, patient-controlled analgesia (PCA) uses a fixed-rate continuous background infusion mode. However, some patients suffer from inadequate analgesia or opioid-related adverse effects due to the biphasic pattern of postoperative pain. Therefore, we investigated the postoperative analgesic efficacy of PCA using an optimizing background infusion mode (OBIM), where the background injection rate varies depending on the patient's bolus demand. Materials and Methods: We prospectively enrolled 204 patients who underwent laparoscopic cholecystectomy in a randomized, controlled, double-blind study. Patients were allocated into either the optimizing (group OBIM) or the traditional background infusion group (group TBIM). The numeric rating scale (NRS) score for pain was evaluated at admission to and discharge from the recovery room, as well as at the 6th, 24th, and 48th postoperative hours. Data of bolus demand count, total infused volume, and background infusion rate was downloaded from the PCA device at 30-min intervals until the 48th postoperative hour. Results: The NRS score was not significantly different between groups throughout the postoperative period (P = 0.621), decreasing with time in both groups (P < 0.001). The bolus demand count was not significantly different between groups throughout (P = 0.756). The mean cumulative infused PCA volume was lower in group OBIM [84.0 (95% confidence interval: 78.9−89.1) mL) than in group TBIM [102 (97.8−106.0) mL] (P < 0.001). The background infusion rate was significantly different between groups throughout (P < 0.001); it was higher in group OBIM than in group TBIM before the 12th postoperative hour, and lower from the 18th to the 48th postoperative hours. Conclusions: The OBIM combined with bolus dosing is useful in that it reduces the cumulative PCA volume compared to the TBIM combined with bolus dosing, while yielding comparable postoperative analgesia and bolus demand in patients undergoing laparoscopic cholecystectomy.
Modeling the Water Scrubbing Process and Energy Requirements for CO2 Capture to Upgrade Biogas to Biomethane

Water scrubbing is the most widely used technology for removing CO2 from biogas and landfill gas. This work developed a rate-based mass transfer model of the CO2–water system for upgrading biogas in a packed bed absorption column. The simulated results showed good agreement with both a pilot-scale plant operating at 10 bar, and a large-scale biogas upgrading plant operating at atmospheric pressure. The calculated energy requirement for the absorption column to upgrade biogas to 98% CH4 (0.23 kWh Nm–3, or 4.2% of the input biogas) is a significantly closer approximation to the measured value (0.26 kWh Nm–3, or 4.8% of the input biogas) than has previously been reported in the literature. The model allows for improved design of CO2 capture and biogas upgrading operations and can also be a useful tool for more detailed cost–benefit analysis of the technology.
Data-Driven Multi-Energy Investment and Management Under Earthquakes

Seismic events can severely damage both electricity and natural gas systems, causing devastating consequences. Ensuring the secure and reliable operation of the integrated energy system (IES) is of high importance to avoid potential damage to the infrastructure and reduce economic losses. This article proposes a new optimal two-stage optimization to enhance the reliability of IES planning and operation against seismic attacks. In the first stage, hardening investment on the IES is conducted, featuring preventive measures for seismic attacks. The second stage minimizes the expected operation cost of emergency response. The random seismic attack is modeled as uncertainty, which is realized after the first stage. An explicit damage assessment model is developed to define the budget set of the uncertain seismic activity. Based on the survivability of transmission lines and gas pipelines of IES, an optimal system investment plan is developed. The problem is formulated as a two-stage distributionally robust optimization (DRO) model, which is tested on an integrated IEEE 30-bus system and 20-node gas network. Case studies demonstrate that the two-stage DRO outperforms robust optimization and a single-stage optimization model in terms of minimizing the investment cost and expected economic loss. This article can help system operators to make economical hardening and operation strategies to improve the reliability of IES under seismic attacks, thus managing a more robust and secure energy system.
Ivermectin as Pre-exposure Prophylaxis for COVID-19 among Healthcare Providers in a Selected Tertiary Hospital in Dhaka – An Observational Study

Introduction: While multiple vaccines are undergoing clinical trial across the globe, we yearn for an FDA approved drug to protect us from the devastating pandemic for the time being. This study aims to determine the effectiveness of Ivermectin when administered as pre-exposure prophylaxis for COVID-19. Method: An observational study, with 118 healthcare providers who were enrolled purposively, was conducted in a tertiary hospital in Dhaka from May 2020 to August 2020. The subjects were divided into experimental and control groups; and the experimental group received an oral monthly dose of Ivermectin 12mg for 4 months. Both groups were exposed to COVID-19 positive patients admitted in the hospital during the course of study. The symptomatic subjects were evaluated by physical examination, COVID-19 RT-PCR and/or HRCT of chest. Differences between the variables were determined using the Chi-square test and the level of statistical significance was reached when p<0.05. Result: 73.3% (44 out of 60) subjects in control group were positive for COVID-19, whereas only 6.9% (4 out of 58) of the experimental group were diagnosed with COVID-19 (p-value < 0.05). Conclusion: Ivermectin, an FDA-approved, safe, cheap and widely available drug, should be subjected to large-scale trials all over the world to ascertain its effectiveness as pre-exposure prophylaxis for COVID-19.
Choice of non-linear models to determine the growth curve of meat-type quail

ABSTRACT: The objective of this study was to compare non-linear models fitted to the growth curves of quail to determine which model best describes their growth and check the similarity between models by analyzing parameter estimates.Weight and age data of meat-type European quail (Coturnix coturnix coturnix) of three lines were used, from an experiment in a 2 × 4 factorial arrangement in a completely randomized design, consisting of two metabolizable energy levels, four crude protein levels and six replicates. The non-linear Brody, Von Bertalanffy, Richards, Logistic and Gompertz models were used. To choose the best model, the Adjusted Coefficient of Determination, Convergence Rate, Residual Mean Square, Durbin-Watson Test, Akaike Information Criterion and Bayesian Information Criterion were applied as goodness-of-fit indicators. Cluster analysis was performed to check the similarity between models based on the mean parameter estimates. Among the studied models, Richards’ was the most suitable to describe the growth curves. The Logistic and Richards models were considered similar in the analysis with no distinction of lines as well as in the analyses of Lines 1, 2 and 3.
Extended Atomic Structure Calculations for W11+ and W13+

We report an extensive and elaborate theoretical study of atomic properties for Pm-like and Eu-like Tungsten using Flexible Atomic Code (FAC). Excitation energies for 304 and 500 fine structure levels are presented respectively, for W11+ and W13+. Properties of the 4f-core-excited states are evaluated. Different sets of configurations are used and the discrepancies in identifications of the ground level are discussed. We evaluate transition wavelength, transition probability, oscillator strength, and collisional excitation cross section for various transitions. Comparisons are made between our calculated values and previously available results, and good agreement has been achieved. We have predicted some new energy levels and transition data where no other experimental or theoretical results are available. The present set of results should be useful in line identification and interpretation of spectra as well as in modelling of fusion plasmas.

Synthesis of tercopolymer BA–MMA–VTES and surface modification of nano-size Si3N4 with this macromolecular coupling agent

A new macromolecular coupling agent butyl acrylate (BA)-methyl methacrylate (MMA)-vinyl triethoxy silane (VTES) tercopolymer was synthesized using solution polymerization initiated by free radical initiator benzoyl peroxide (BPO) and dicumyl peroxide (DCP). Dodecylthiol is choosed as the chain transfer to control the molecule weight of this tercopolymer. The terpolymer's molecular structure was confirmed by FTIR and NMR, and its average molecular weight was determined by GPC. In this work, the tercopolymer BA–MMA–VTES is used for surface modification of silicon nitride (Si3N4) nanopowder. The structure surface properties and thermal stability of modified nano-Si3N4 were systematically investigated by FTIR, TGA, TEM, and size distribution analyzer. The results show that the macromolecular coupling agent bonds covalently on the surface of nano-sized Si3N4 particles and an organic coating layer is formed. The optimum loading of this macromolecular coupling agent BA–MMA–VTES tercopolymer is 5% (wt %) of nano-sized Si3N4. TEM also reveals that modified nano-Si3N4 possesses good dispersibility. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

Evaluating the performance of an Ingot wavefront sensor for the ELT: good news from simulations

As the new generation of telescopes is coming soon, we need to solve or improve some issues related to the adaptive optics techniques, necessary to fully exploit their extraordinary capabilities in terms of sensitivity and resolution. The Ingot wavefront sensor was thought to overcome some limitations due to the use of artificial sources instead of natural ones: it is designed to cope with the typical elongation of Sodium Laser Guide stars that will be used by the ELTs. Here we present the preliminary tests we performed to properly set up an end-to-end simulator, in order to evaluate the performance of such a device. We describe the different configurations considered and the assumptions we made, discussing also some computational problems we faced building up the tool. We also show the results of the first simulations obtained closing the loop with a mock ELT telescope.
Stress, Emotion Regulation, and Well-Being among Canadian Faculty Members in Research-Intensive Universities

Existing research reveals the academic profession to be stressful and emotion-laden. Recent evidence further shows job-related stress and emotion regulation to impact faculty well-being and productivity. The present study recruited 414 Canadian faculty members from 13 English-speaking research-intensive universities. We examined the associations between perceived stressors, emotion regulation strategies, including reappraisal, suppression, adaptive upregulation of positive emotions, maladaptive downregulation of positive emotions, as well as adaptive and maladaptive downregulation of negative emotions, and well-being outcomes (emotional exhaustion, job satisfaction, quitting intentions, psychological maladjustment, and illness symptoms). Additionally, the study explored the moderating role of stress, gender, and years of experience in the link between emotion regulation and well-being as well as the interactions between adaptive and maladaptive emotion regulation strategies in predicting well-being. The results revealed that cognitive reappraisal was a health-beneficial strategy, whereas suppression and maladaptive strategies for downregulating positive and negative emotions were detrimental. Strategies previously defined as adaptive for downregulating negative emotions and upregulating positive emotions did not significantly predict well-being. In contrast, strategies for downregulating negative emotions previously defined as dysfunctional showed the strongest maladaptive associations with ill health. Practical implications and directions for future research are also discussed.
Perforated Baffles for the Optimization of Disinfection Treatment

Water disinfection is one of the main treatments aimed at maintaining human health. Traditionally, the treatment takes place inside multichamber tanks that facilitate the contact between disinfectant and pathogenic microorganisms to be removed. However, the traditional contact tanks used for disinfection have geometric characteristics causing the formation of dead or recirculation zones that reduce treatment efficiency with potentially harmful effects on human health. This study proposes the creation of holes in the baffles that divide the various chambers in order to increase the mixing inside the reactor. In particular, various configurations with holes of different sizes were considered. The results obtained through fluid dynamics simulations based on the LES (large eddy simulation) model show that the jet emerging from the holes penetrates the recirculation zones, transforming them into areas of active mixing. The analysis of the hydraulic mixing indices traditionally used to evaluate the performance of these tanks shows that the presence of the holes allows a significant increase in the mixing efficiency by reducing the short-circuit phenomena and the entrapment of the disinfectant inside the dead zones. Parameters of fundamental importance are the size of the holes, the arrangement of the holes within the baffles and the perforation percentage.
Outcomes of the IXPE instrument calibration

IXPE (Imaging X-ray Polarimetry Explorer) is the next Nasa Small Explorer mission foreseen for the lunch in 2021. It is a partnership with the Italian Space Agency (ASI). IXPE is devoted to X-ray polarimetry in the 2-8 keV energy band. The IXPE telescope comprises three grazing incidence mirror modules coupled to three detector units hosting each one a Gas Pixel Detector (GPD) polarimeter. The GPD exploits the photoelectric effect to measure the linear polarization of the X-ray emission from astrophysical sources. A wide and accurate on ground calibration was carried out on the IXPE detector units at INAF-IAPS in Italy. A dedicated facility was set-up to calibrate the detector units with polarized and unpolarised X-rays at different energies before Instrument integration.
Psychiatric Comorbidities among Children with Attention Deficit Hyperactivity Disorders

Background and Purpose: Attention Deficit Hyperactivity Disorder (ADHD) is the most common neurodevelopmental disorder in children. The purpose of this study is to explore the rate of psychiatric comorbidities among children with ADHD and investigating the impact of comorbidities on function of children. Subjects and Methods: Sixty-four children of both genders who fulfilled DSM-5 criteria for ADHD were included. All subjects were subjected to IQ assessment, Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS), Conners Rating Scale, and Child Behavior Check List (CBCL). Results: Combined subtype was the commonest (50%) followed by hyperactive-impulsive (31.25%), then inattentive (18.75%). Psychiatric comorbid disorder among pediatric cases with ADHD was ODD (31.25%), followed by nocturnal enuresis (23.44%), conduct disorders (18.75%), motor tic disorders (15.63%), anxiety disorders (12.50%), depressive disorders (10.94%), substance abuse disorders (9.38%), autism spectrum disorders (7.81%), vocal tic disorders (1.56%). There was a statistically significant difference between gender and conduct disorder and SUDs (P <0.05). There was no significant difference in the distribution of comorbidities among subtypes except for conduct disorder (P<0.05). There was a significant difference between Original Research Article Shaaban et al.; JAMMR, 32(23): 85-96, 2020; Article no.JAMMR. 62618 86 comorbidities and severity of ADHD, according to the Conners scale (P<0.05). There was a significant difference between comorbidities number and different CBCL parameters (P<0.05). There was a significant negative correlation between the number of comorbidities and total competence and positive correlation with the total problem (P<0.05). Conclusions: The presence of comorbid disorders among pediatric cases with ADHD is the rule rather than the exception. Oppositional defiant disorder, followed by nocturnal enuresis, are the most common comorbid diseases. Comorbidities number is negatively correlated with total competence and positively correlated with the total problem.
Development of the CECER-DLL child and family questionnaire: a new tool for documenting the language and literacy experiences of Latino/a dual language learners

ABSTRACT As the number of dual language learners (DLLs) increases globally, it is critical that well-developed questionnaires are available to researchers and educators that capture the characteristics and language experiences of preschool DLLs and their families. To fill this need, the Center for Early Care and Education Research-Dual Language Learners (CECER-DLL) Child and Family Questionnaire was developed. This article describes the four-step iterative process that was used to create the questionnaire, with a particular focus on the cognitive interviews that were conducted to establish the validity of the items. Findings from the cognitive interviewing process are presented which demonstrate the importance of this step when creating questionnaires that are valid for diverse populations. The development process of the CECER-DLL Child and Family Questionnaire, which is now available to the field, serves as an example of how to create well-designed questionnaires for other populations of DLLs in the United States and beyond.
Difference in tick infestations

The aim of this study was to identify the species and parasitic indices of ticks. A flock of 57 individuals (sheep, goats, cattle and dogs) in southern Algeria was studied from March 2019 to February 2020 during monthly visits. A total of 2544 ticks were collected by examining the entire body of the animal. Two tick species were identified: Hyalomma dromedarii (2430 ticks) and Rhipicephalus sanguineus sensu lato (114 ticks). The first species had annual activity and consisted only of adults, while the second species had spring and summer activity and contained both adults and nymphs. At the annual level, the prevalence of infestation, abundance, and intensity were 38.60%, 44.63 and 115.64 ticks per animal, respectively. At the monthly level there were species specific fluctuations, with a peak in activity in September.
Acute Diarrhea in Children Less than Five Years of Age: Epidemiology of Bacterial Pathogens

Objectives: Acute diarrhea is among the leading causes of mortality and morbidity worldwide. Bacteria tend to cause more fatal illnesses and complications such as septicemia and persistent diarrhea. This study aimed to determine the causes of acute diarrhea, laboratory and clinical predictors of bacterial causes, and antimicrobial resistance pattern among the isolates among children in Dar es salaam, Tanzania. Methods: A cross-sectional hospital-based study was conducted in Dar es salaam Hospitals from April 2015 to March 2016 among children below five years of age who presented with acute diarrhea. Demographic characteristics and results from stool specimen analysis, complete blood count, C- reactive protein and antimicrobial resistance results were recorded using a pre-structured clinical research form. Results: Among 200 children enrolled, viruses were identified in 149 (74.5%) of the cases. Bacterial pathogens were found in 15 (7.5%) cases only. Elevated stool red blood cell count, stool white blood cell count, and fever were highly associated with enteric bacterial pathogens (p<0.001, p=0.002 and p=0.04 respectively). Most of the bacterial isolates were resistant to Cotrimoxazole and erythromycin but highly sensitive to ciprofloxacin and Ceftriaxone. Conclusion: Fever, elevated stool leukocyte and elevated stool red blood cells are significant predictors of bacterial enteric pathogens in children with acute diarrhea. These parameters may guide clinicians in resource-limited settings in the diagnosis and management of acute diarrhea. Further studies should be conducted to determine local antimicrobial resistance patterns. J Microbiol Infect Dis 2020; 10(3): 208-214.
Enquadramentos na medicina regenerativa: os relatos recentes na imprensa brasileira

Mass media works as a bridge between medicine and the public and produces an impact according to how information is organized and presented. A quantitative and qualitative content analysis was developed on the main framings on regenerative medicine found in reports by the newspapers Folha de S.Paulo and Reciis – Rev Eletron Comun Inf Inov Saúde. 2020 out. -dez. ;14(4):942-59 | [www.reciis. icict.fiocruz. br] e-ISSN 1981-6278 Artigo original | Enquadramentos na medicina regenerativa: os relatos recentes na imprensa brasileira 943 O Globo between January 2012 and May 2019. The analysis found limitations in the information published: a reduced number of stories, the presence of few articles on social and regulatory controversies and a portrayal of over-optimistic accounts on the benefits of cellular-based therapies. The article concludes that there is a lack of a more systematic contribution of the printed press to the social and institutional legitimation of the local area, one developed with public resources and that offers a valuable opportunity to raise awareness on collective health, as well as, for a competitive inclusion of Brazil at the global level.
