Preparation and morphological studies of tin sulfide nanoparticles and use as efficient photocatalysts for the degradation of rhodamine B and phenol
Authors: Oluwalana Abimbola E. , Ajibade Peter A.
Published: February 2022

Tin sulfide nanoparticles were prepared from tin(ii) dithiocarbamate complexes: bis(benzylmethyl dithiocarbamate)tin(ii) (SnS1), bis(dibenzyl dithiocarbamato)tin(ii) (SnS2), and bis(imidazolyldithiocarbamato)tin(ii) (SnS3) single-source precursors. Powder X-ray diffraction patterns of the as-prepared tin sulfide nanoparticles confirmed orthorhombic crystalline phase irrespective of the tin(ii) dithiocarbamate precursors used to prepare the tin sulfide nanoparticles. Transmission electron microscopic images showed SnS nanoparticles with average particle size of 1.35 ± 0.04 nm for SnS1, 2.63 ± 0.65 nm for SnS2, and 1.55 ± 0.15 nm for SnS3. The energy bandgap of the SnS nanoparticles obtained from Tauc plots are in the range 3.80–4.37 eV. The as-prepared SnS nanoparticles were used as photocatalysts for the degradation of rhodamine B with efficiency of 90.97, 61.53, and 80.26% for SnS1, SnS2, and SnS3, respectively, while for phenol degradation efficiency was 96.45, 75.13, and 90.69% after 180 min. The results indicate that the as-prepared SnS nanoparticle are efficient photocatalyst for rhodamine B and phenol degradation. The photocatalytic degradation of rhodamine B and phenol follows pseudo-first-order reaction kinetics model from which the photodegradation rate could be obtained. Scavenger studies show that electrons (e−), hydroxy radicals (˙OH), and holes (h+) play significant role in the photodegradation of rhodamine B and phenol by the SnS nanoparticles. Recyclability studies show the SnS photocatalyst could be reused for four cycles without losing its photodegradation ability.
Referential accessibility as an index of the discourse functions of predicative and specificational clauses
Authors: van Praet Wout
Published: February 2022

This paper studies referential accessibility marking in predicative and specificational clauses, in particular the ones in which the roles of ‘description’ and ‘variable’ are realised by an indefinite NP (e.g. He is a baker
vs.
One of his talents is pastry). While the indefinite NP in the two clause types has been studied in detail, little is known about how the other two roles – of ‘describee’ and ‘value’ – are typically realised. This study, therefore, examines the choice of referring expressions for the items filling these roles, as an index of their retrievability and degree of accessibility. The analysis is based on 750 corpus examples from spoken and written British English. Moreover, since specificational clauses allow for the value to be either complement or subject, this study also provides insight into what may motivate the choice for one pattern or the other. Significant differences were found between describees and values, as well as between value-subjects and value-complements. These findings are interpreted as indicative of different discourse functions of the three constructions. While predicative clauses typically elaborate familiar information, specificational clauses serve a broader discourse-organising function: starting a new discourse-topic, pivoting from one topic to another, or summarising prior propositions as concluding a topic.

Authors: Criss Michelle G. , Wingood Mariana , Staples William H. , Southard Veronica , Miller Kenneth L. , Norris Traci L. , Avers Dale , Ciolek Cathy H. , Lewis Carole B. , Strunk Ellen R.
Published: February 2022

Geriatric physical therapy requires a unique skill set and knowledge to provide best practice care. The skill set requires clinicians to recognize the significance of the continuum of aging from optimal to pathology-influenced aging and how psychosocial, environmental, behavioral, accessibility, and economic factors affect this aging continuum, optimal health, and wellness. Employing this distinctive skill set while also utilizing evidence-based practice, acknowledging the variability observed in older adults, and utilizing interwoven care systems that impact outcomes are key characteristics of best practice. The Academy of Geriatric Physical Therapy developed best practice guidelines consisting of 6 principles needed to ensure patients receive the care that they deserve. Best practice principles include person-centered care, anti-ageist beliefs, holistic assessment using sound outcome measures, evidence-based interventions, physical activity promotion, and interprofessional collaborative practice. This executive summary presents these principles along with suggested action steps for each element of best practice. The aims are to encourage individual self-assessment, promote improvement in practice on an individual and facility/system level, increase communication and collaboration with other health care providers about global best practices for older adults, and to further target education, resources, and advocacy toward achieving best practice on a larger scale.
Structural diversity and biological activities of caged Garcinia xanthones: recent updates
Authors: Phang Yee Lin , Zheng Changwu , Xu Hongxi
Published: February 2022

Caged xanthones are a class of natural compounds with approximately 200 members that are commonly isolated from the Garcinia genus in the Clusiaceae (formerly Guttiferae) family. They are often characterized by a notable 4-oxa-tricyclo[4.3.1.03,7]dec-2-one (caged) architecture with a common xanthone backbone. Because most caged xanthones have potent anticancer properties, they have become a target of interest in natural product chemistry. The unique chemical architectures and increasingly identified biological importance of these compounds have stimulated many studies and intense interest in their isolation, biological evaluation and mechanistic studies. This review summarizes recent progress and development in the chemistry and biological activity of caged Garcinia xanthones and of several compounds of non-Garcinia origin, from the years 2008 to 2021, providing an in-depth discussion of their structural diversity and medicinal potential. A preliminary discussion on structure-activity relationships is also provided.

Published: February 2022

Background and Objective: One of the ordinary problems throughout orthodontic treatment is bracket debonding , which affect treatment course and results in increased treatment duration and more clinical time for bonding again of failed brackets This study aimed to evaluate the shear bond strength(SBS) of brackets bonded to demineralized enamel pretreated with fluoride varnish (3M),sodium hypochlorite NaClO 5% and low viscosity Icon Infiltrant resin (DMG)and laser ( YAG) with fluoride and evaluation of the adhesive remnant index (ARI) on the deboned bracket. Materials and method: A total of 65 human maxillary premolar teeth were assigned in to five groups (n=13) Groups. The surface of all groups were submitted to demineralized solution, and the first groups was the demineralized group (left with no treatment), second and third groups (demineralized) were treated with fluoride varnish 5% (Clinpro White Varnish, 3m ESPE) and 5.5% sodium hypochlorite NaClO, fourth and fifth group (demineralized) were treated with Infiltrate resin (Icon, DMG) and laser (Er,Cr:YSGG laser,Waterlase® iPlusTM). Shear bond strength(SBS) was evaluated by means of a universal testing machine, and Stereomicroscope was used to determine (ARI) at x20 magnification. Data were analyzed using the Statistical Package for Social Sciences (SPSS, version 22). Kruskal Wallis test was used to analyze the bond strength data and adhesive remnant index (ARI). Results: Notable difference was observed in the shear bond strength of all groups. The bond strength of the demineralized group, which treated by fluoride varnish 5% (Clinpro White Varnish, 3m ESPE) was significantly lower than the other groups. According to the (ARI) most samples in all groups show score 0 which means the failure zone inside demineralized enamel surface Conclusion: Fluoride varnish, infiltrate resin (Icon, DMG) and laser were failed to improve SBS (shear bond strength) of brackets on demineralized teeth.

Published: February 2022

While altered precipitation regimes can greatly impact biodiversity and ecosystem functioning, we lack a comprehensive view of how these impacts are mediated by changes to the seasonality of precipitation (i.e., whether it rains more/less in one season relative to another). Over 2 years, we examined how altered seasonal precipitation influenced annual plant biomass and species richness, Simpson’s diversity, and community composition of annual plant communities in a dryland ecosystem that receives both winter and summer rainfall and has distinct annual plant communities in each season. Using a rainfall exclusion, collection, and distribution system, we excluded precipitation and added water during each season individually and compared responses to control plots which received ambient summer and winter precipitation. In control plots, we found five times greater annual plant biomass, twice as many species, and higher diversity in winter relative to summer. Adding water increased annual plant biomass in summer only, did not change richness or diversity in either summer or winter, and modestly shifted community composition. Excluding precipitation in either season reduced annual plant biomass, richness, and Simpson’s diversity. However, in the second winter season, biomass was higher in the plots where precipitation was excluded in the previous summer seasons suggesting that reduced productivity in the summer may facilitate biomass in the winter. Our results suggest that increased precipitation in summer may have stronger short-term impacts on annual plant biodiversity and ecosystem function relative to increased winter precipitation. In contrast, decreasing precipitation may have ubiquitous negative effects on annual plants across both summer and winter but may lead to increased biomass in the following off-seasons. These patterns suggest that annual plant communities exhibit asymmetries in their community and ecosystem responses to altered seasonal precipitation and that considering the seasonality of precipitation is important for predicting the effects of altered precipitation regimes.
Is a Non-Capitalist World Imaginable? Embodied Practices and Slipstream Potentials in Amanda Strong’s Biidaaban
Authors: Tedford Matthew Harrison
Published: February 2022

This essay analyzes Michif filmmaker Amanda Strong’s 2018 stop-motion film about urban syrup making, Biidaaban (The Dawn Comes) within the context of some scholars’ claim that it is nearly impossible to imagine a world outside of capitalism. Drawing on decolonial Indigenous political theory and feminist thought, the essay argues that Biidaaban illustrates the political possibilities of Indigenous slipstream, a subgenre of Indigenous science fiction characterized by nonlinear time, to bring about liberatory worlds in the face of forces that make the capitalist order appear natural. Theories of Indigenous aesthetics also highlight how embodied practices—including both syrup making and stop-motion animation—are part of an ongoing process of creation and remaking of the world. These perspectives point to the generative function of visual art, breaking down the boundary between representation and action. Following from these ideas, the essays shows how Biidaaban is an assertion of Indigenous sovereignty and a generative step in the process of world making.

Laccase has huge potential application in all aspects of biotechnology due to the ability of laccase to oxidize a wide range of phenolic and non-phenolic compounds. The future success of such applications requires large amounts of laccase with low costs. White-rot fungi are important groups of laccase production. In this study, three white-rot fungi, Phlebia acerina Han 618, Trametes hirsuta Han 726, and Coriolopsis trogii Han 751, isolated from a native North China habitat, were identified by the method of molecular biology and preliminary screening of the ability of laccase-production by guaiacol selection medium. Then they were fermented on different lignocellulosic biomass. Three species showed consistency in preference of lignocellulosic biomass, and the presence of stalk of Sorghum bicolor was more suitable for secreting laccase. The capacity of laccase secretion from different species was significantly different. The capacity of secreting laccase of C. trogii Han 751 was superior to that of P. acerina Han 618 and T. hirsuta Han 726. The discovery of a new strain with superior capacity of secreting laccase and suitable lignocellulosic biomass were helpful for laying a foundation for the optimization of the fermentation conditions for the highest laccase production, the isolation and purification of laccase, and the industrial application of laccase.
Thermo-Vibro-Mechanic® (TVM) wood densification method: Mechanical properties
Authors: Budakçı Mehmet , Şenol Süleyman , Korkmaz Mustafa
Published: February 2022

A densification method is proposed and developed to improve the mechanical properties of Uludağ fir (Abies bornmüelleriana Mattf.) and black poplar (Populus nigra L.) woods. The method, called Thermo-Vibro-Mechanic® densification, is derived from the hypothesis that the vibration added to the traditional thermo-mechanical densification process can cause the wood cell walls to interlock with each other at the micro-level via the friction effect. In addition, it aims to remove the cell cavities under lower pressure compared to other densification methods via the shaking effect. To test this hypothesis, the samples, obtained in both the radial and tangential directions, were pre-treated with wood stain and preservative before undergoing the densification process. Thermo-Vibro-Mechanic® densification was performed at varying temperatures (100, 120, and 140 °C), pressures (0.60, 1.00, and 1.40 MPa), and durations (20, 60, and 100 s). The changes in the values of the bending strength, modulus of elasticity, and compression strength parallel to the grain in the radial and tangential directions were determined accordingly. The results showed that the Thermo-Vibro-Mechanic® densification process increased the bending strength and modulus of elasticity values up to 50%, while the compression strength reached 67% higher than the untreated wood.

Published: February 2022

In recent years, people’s acceptance of online shopping has increased markedly with the gradual maturing of e-commerce. The furniture industry in China, along with many other countries, is paying increased attention to the online retail business. The furniture online consumption experience has attracted attention both in academic and industrial fields. The purpose of this paper is to provide a literature review of the furniture online consumption with an aim to extend the concept of consumer experience to the context of online furniture consumption. The paper offers three important contributions for both academics and practitioners. First, it analyzes the main influencing factors of the consumer experience concerning wood furniture online consumption in China. And secondly, it proposes a conceptual framework of furniture online consumer experience (FOCE), which divides online consumption experience into three dimensions: perceived risk experience, emotional experience, and new technology interactive experience. Finally, from a managerial perspective, the authors put forward constructive strategies in terms of furniture online sales. The findings of this study afford practical implications for the improvement of the online shopping experience of consumers for furniture companies.
Determination of changes in the mechanical and color properties of some wood species treated with shellac
Authors: Sözen Eser
Published: February 2022

The properties of wood, which is a natural and sustainable substance, change under biotic and abiotic factors. Different methods along with chemical/natural substances are used to extend the service life of wood and increase its performance under different conditions. Shellac is a natural product secreted by insects onto host trees. It is used extensively as a coating, especially in the food and pharmaceutical industries. Its natural properties and biocompatibility increase the areas where it is used. This study investigated the effects on the physical and mechanical properties of pine, beech, and fir species impregnated with shellac solutions at different concentrations (1%, 3%, and 5%) and sodium hydroxide (NaOH). The study found that 10% NaOH solution caused significant decreases in the bending strength values. The highest bending strength values were obtained for the Scots pine and fir woods at 5% shellac concentration and for the beech wood at 1% concentration. The highest modulus of elasticity (MOE) values were reached at 1% shellac concentration in all three tree species. Although the lightness (L*) of the wood samples decreased with shellac impregnation, the chromatic coordinate (a* and b*) values increased. According to the Fourier-transform infrared (FTIR) spectroscopy results, changes were determined in the chemical structures of the wood samples impregnated with NaOH, whereas the shellac did not cause a change in the chemical structure of the wood samples.

The performance of a particleboard seems to be related to the chemical constituents of the species and the size distribution the particles. Neolamarckia cadamba (NC) and Leucaena leucocephala (LL) are fast growing species and good potential resources for particleboard production. This study examined the chemical contents of both species, as well as the mechanical and physical performance of particleboard made with 100% NC, 100% LL, and their 50:50 admixtures. High moisture resistance boards were prepared using melamine urea formaldehyde (MUF) at a content of 10, 12, and 14 %. The 30% extra buffering of LL translated to its lower performance for both mechanical and physical properties. The 50:50 admixtures provided enticing results, as it counteracts the impact of lowered performance of 100% LL. All boards passed the mechanical requirements of the BS EN 312 (2003) standard, but they did not meet the requirement for thickness swelling. The internal bond for cyclic test only failed for 100% LL with 10% resin added. With use of wax, the potential of improvement in swelling properties is possible.
Influence of the main neutron absorbers poisons coupled to the Point Kinetics model by the Rosenbrock’s method
Authors: Schaun Natália Barros , Tumelero Fernanda , Petersen Claudio Zen
Published: February 2022

In this work, the Neutron Point Kinetics equations are solved for six groups of delayed neutron precursors and different types of ramp reactivity, considering the temperature effects by the Rosenbrock’s method, to verify the methodology. Furthermore, the classical model is solved by inserting the effects of the main neutron poisons, considering constant reactivity for a group of precursors. The simulation consists of inserting a negative constant reactivity, simulating a reactor in its shutdown phase. Then, positive constant reactivity is inserted, simulating power resumption in a reactor already poisoned, to analyzing the final behavior of the neutron density. The simulation achieved its goal of simulating the behavior of the neutron poisons, so that the graphs make physical sense as expected. Therefore, it was found that the proposed method overcame the stiffness of the Neutron Point Kinetics model, and also solved a nonlinear problem by the inclusion of temperature and neutron poisons in the system.

Consensus protocol organizes gastric emptying scintigraphy (GES). There is low adherence to the protocol, and its applicability is reduced due to poor connection between retention and functional disorders. To optimize the consensus protocol, we added a dynamic acquisition and quantification of distinct parameters for healthy and dyspeptic subjects. Fourteen patients with functional dyspepsia (FD) and 20 healthy volunteers were undergone GES. The dynamic acquisition was added to the activity versus time curve composed of 4-time points (0, 60, 120, and 240 min) preconized. A dynamic set of 3060 images (1 Hz) were acquired between immediate and 60 min static images. Regions of interest were drawn to divide the stomach internally, and two gastric segmentations (similar areas and incisura) were adopted for all quantification of global GE and contractile parameters. Gastric retention at 4-time points preconized was not enough to identify differences between FD and healthy volunteers (R² = 0.99; p ˂ 0.0009). Retention percentage of test meal in the proximal stomach employing segmentation, T1/2, MGET and lag phase analysis were higher in dyspeptic compared to healthy volunteers.  Impaired intragastric meal distribution was observed in FD by similar areas (p < 0.02) and incisura (p < 0.001). Reduction in the amplitude of contraction from the proximal region (p ˂ 0.015 and p ˂ 0.003) was observed in FD segmentation by similar areas and incisura, respectively. Impaired proximal stomach was observed in functional dyspepsia due to the insertion of dynamic acquisition proposed by consensus. Our approach can strengthen the consensus protocol and makes it capable of recognize and classify some diseases.

Published: February 2022

The aim of this study was to evaluate the feasibility of using acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) 3D printing filaments as materials for mammography phantom construction, comparing their attenuation properties at two different set-ups: at a Calibration Laboratory and directly to a mammography unit. The attenuation of 3D printed test phantoms of two types of common 3D printing Fused Filament Fabrication (FFF) filaments (ABS and PLA) were characterized in comparison with polymethylmethacrylate (PMMA). The measurements were carried out with standard IEC 61267 X-rays, using RQR 2-M and RQR 4-M beam qualities at the Instruments Calibration Laboratory, and then applied to a mammography unit, with measurements with 28 kVp and 35 kVp. Attenuation characteristics evaluated indicates the suitable equivalence of PLA to PMMA for 3D printing breast tissue equivalent complex phantoms. The plastic materials used in this study suggest that the FFF technique may be suitable for mammography phantom development.

Very High Temperature Gas Cooled Reactors - VHTGRs are studied by several research groups for the development of advanced reactors that can meet the world's growing energy demand. The analysis of the flow of helium coolant around the various geometries at the core of these reactors through computational fluid dynamics techniques is an essential tool in the development of conceptual designs of nuclear power plants that provide added security. This analysis suggests a close analogy with aeronautical cases widely studied using computational numerical techniques to solve systems of governing equations for the flow involved. The present work consists in using the DISSIPA2D_EULER code, to solve the Euler equations in a conservative form, in two-dimensional space employing a finite difference formulation for spatial discretization using the Euler method for explicit marching in time. The physical problem of supersonic flow of helium gas along a ramp and diffusor configurations is considered. For this, the Jameson and Mavriplis algorithm and the linear artificial dissipation model of Pulliam was implemented. A spatially variable time step is employed aiming to accelerate the convergence to the steady state solution. The main purpose of this work is obtain computational tools for flow analysis through the study the cited dissipation model and describe their characteristics in relation to the overall quality of the solution, as well as obtain preliminary results for the development of computational tools of dynamic analysis of helium gas flow in gas-cooled reactors.

Published: February 2022

The use of 3D printing technologies is growing widely, including the possibility of design phantoms for imaging and dosimetry. For that, high attenuation tissues such as cortical bone, dentin and enamel need to be mimicked to accurately produce 3D printed phantoms, especially for Fused Filament Fabrication (FFF) printing technology.  A Radiopaque FFF filament commercially available had been hard to be found; and this study aims to report, step-by-step, the development of a radiopaque FFF filament. A combination of radiopaque substances (Barium Sulfate - BaSO4 and Calcium Carbonate - CaCO3) was selected using the National Institute of Standards and Technology (NIST) XCOM tool theoretical data and added as filler in an Acrylonitrile Butadiene Styrene (ABS) matrix. The filament was homogenized and gone under first characterizations by analyzing its density, Scanning Electron Microscopy (SEM), Computed Tomography (CT) and micro-CT (µCT) scans. Three filaments were produced with different Hounsfield Units (HU) equivalences: XCT-A (1607HU), XCT-B (1965HU) and XCT-C (2624HU) with respective densities of 1.166(6) g/cm³, 1.211(2) g/cm³ and 1.271(3) g/cm³. With these values, high attenuation tissues, such as bones, dentine and enamel, can now be mimicked with FFF 3D printing technology, at a low cost of production.

Published: February 2022

The Physical Protection System is based on the five basic security functions (deterrence, detection, delay, response, and security management), all of which are required to protect a radiological facility against malicious acts. Evaluating the performance of PPS, including the security procedures and their implementation, is a way to engage with staff, raise their awareness on the importance of security. This article presents a new effectiveness evaluation model of the PPS administrative structure through qualitative analysis, which is appropriate for the security management evaluation of low-consequence radiological facilities, to protect them against malicious acts. This model was developed in five stages to obtain a structured process for conducting the PPS administrative structure evaluation, based on the security management function, consisting of 11 topics and 89 qualitative questions to determine the Relative Robustness Index of this function. Model topics were classified with distinct relative weights based on their relevance to the PPS. For testing and validation of the model, 6 industrial radiological facilities classified in different security levels were selected. The results showed that the self-assessment model proposed in this article is viable, considering its simplicity, promptness, and applicability in identifying and analyzing the strengths and weaknesses of the PPS security management function. The new model made possible the effectiveness evaluation of the PPS globally and punctually, making it possible to identify which topics of security management are above, or below, the minimum required for the current security level.

The article describes the tool, which was formed and tested to assess politicians’ emotional attitude to predict the impact of affective polarization on the nature of political confrontations. Plutchek’s theoretical scheme of emotions has been operationalized, the tool for assessing emotional perception has been proposed, and its use for measuring the President’s emotional perception has been tested. Eight basic attitudes that can be used as the foundation for behavioural matrices, representing different types of links between emotional evaluations and behavioural attitudes, have been modelled. The tool was tested during the survey with the participation of 1420 respondents. There have been identified two latent factors, which demonstrate the internal connection of eight pairs of bipolar emotions concerning the figure of the President. The first factor covers the emotions of defeat, the second is – emotions of victory. As far as the emotional attitude to the President is concerned, the presence of an emotional split between those who voted for him and those who were against him has been confirmed. It was found out that the structure of the emotional perception of the President by the winners is mobile and combines both positive and negative emotions. At the same time, the structure of the emotional attitude of the losers is monochrome and is mainly represented by negative emotions. Comparison of emotional profiles of representatives of polar groups revealed that the behavioural model of the defeated is formed by mixing two fundamental attitudes, those of the Distressed and the Rejected. The behavioural model of the winners is formed on the ground of the essential attitude, that of the Stakeholders. The emotional profile of those who did not vote for any of the candidates is generally closer to the profile of the winners. Significant differences in the emotional perception of the President between those who voted for and against him have been defined. There have also been fixed the peculiarities of emotional perception of the figure of the President, depending on the level of education and financial status of the respondents.

The article is devoted to studying visualized values in the social practices of Ukrainian Instagram users. The authors analyse the specifics of post-semiological and socio-dramatic approaches to studying of the visual content of social networks. It has been suggested that photos and videos may represent 1) conscious values of social actors, which they tend to visualize due to their importance, 2) unconscious values, which are involuntarily projected onto the visualized online behaviour. The paper presents the theoretical substantiation of the need to study the values through visuality analysis. The study of visualized values in the social practices of Ukrainian Instagram users was conducted using R. Inglehart’s theory of postmodernization of values, which describes three value patterns – traditional, modernist, and postmodernist. The study aimed to find out which visualized values dominate in the Ukrainian Instagram pool; to conduct a comparative analysis of male and female value preferences in the visual field of Instagram. The results of quantitative content analysis of 2657 photos of Ukrainian Instagram users are presented. It is noted that modernist and postmodernist values are most often visualized in the social practices of Ukrainian Instagram users (38,8% and 41,8%, respectively); the most popular visualized values in female accounts are glamour, environmentalism, and aesthetic perception of life, and in male – friendship, professional self-development, career, and achievement. It is assumed that the visual field of Ukrainian Instagram presents the social actors’ value preferences which can be both conscious and unconscious. It is emphasized that they can anticipate value changes in real life and latently influence the formation of new value patterns. The conclusion is that the visualized values in the social practices of Instagram users can act as predictors of further value transformations in real social life.

We investigate the polymer chain localization in the system of two penetrable interfaces in an external constant magnetic field within the mean-field approximation. The saturation of a polymer chain in the limiting case of zero bulk concentration is studied. We obtain a non-monotonous behavior of the amount of adsorbed polymers as a function of the distance between the interfaces.

Published: February 2022

BACKGROUND

Surgical correction remains the most effective treatment of patients with severe neuromuscular scoliosis (NMS). However, postoperative inpatient clinical care after spinal surgery for NMS patients is highly complex and variable, depending on the provider and/or institution. Our project used a quality improvement methodology to implement a standardized clinical care pathway for NMS patients during their primary spinal surgery, with the global aim of decreasing postoperative hospitalized length of stay (LOS).

METHODS

A multidisciplinary team developed a postoperative pathway for nonambulatory patients with NMS after their primary, nonstaged corrective spinal surgery. The outcome measure was mean LOS, and the process measure was percentage compliance with the newly implemented NMS pathway. The team used statistical process control charts and measures were evaluated over 3 phases to assess the impact of the interventions over time: pretesting, testing, and sustain.

RESULTS

The mean LOS decreased from 8.0 to 5.3 days; a statistically significant change based on statistical process control chart rules. Percentage compliance with the NMS pathway improved during the testing and sustain phases, compared with the pretesting phase. LOS variability decreased from pretesting to the combined testing and sustain phases.

CONCLUSIONS

Using quality improvement methodology, we successfully standardized major components of clinical care for patients with NMS after spinal corrective surgery. Through enhanced care consistency, the mean postoperative LOS decreased by nearly 3 days and decreased LOS variability. Robust multidisciplinary involvement with key stakeholders ensured sustainability of these improvements.

Introduction: Both constraint-induced movement therapy and botulinum toxin
injection are well-researched and described therapeutic interventions in the group of
patients with cerebral palsy. One of the main symptoms of damage to the central nervous
system is excessive muscle tension, which may limit, among many other things, the
manipulative and grasping skills of the upper limb. The most appropriate approach in
patients with hemiplegia seems to be one that is aimed at enabling and then facilitating
the use of the less functional limb. The aim of this study is to evaluate the efficacy
of constraint-induced movement therapy combined with botulinum toxin injection in
paediatric patients with cerebral palsy. Methods: In order to determine the efficacy of
botulinum toxin injection combined with constraint-induced movement therapy, the PubMed
medical database was searched using the following keywords: “botulinum toxin” and
“constraint-induced movement therapy.” The inclusion criteria were the following: only
papers in English and relating to paediatric patients. The literature review was based
on the PRISMA Statement guidelines. Results: As a result of the database search, a total
of 32 articles were found, of which four met the inclusion criteria. The protocols of
all studies varied both in terms of the daily dose of training and the duration of
therapy. Discussion: The combination of constraint-induced movement therapy with
botulinum toxin injection allows for more frequent and effective use of the directly
affected hand in children with cerebral palsy. A longer-lasting constraint-induced
movement therapy with a lower intensity brings better results than a shorter-lasting
therapy with a higher intensity. A significant improvement was observed for the grip
assessment (functional assessment and Quality of Upper Extremity Skills Test – QUEST
scale) and in the Goal Attainment Scaling – GAS results.
Takotsubo syndrome in status epilepticus –case report
Authors: Konopko Magdalena , Hyla Maciej , Owsiak Szymon , Sienkiewicz-Jarosz Halina
Published: February 2022

Takotsubo syndrome, also known as stress cardiomyopathy, apical ballooning
syndrome or “broken heart syndrome,” is a sudden, transient cardiac condition in which
left ventricular dysfunction occurs. Stressors that can induce takotsubo syndrome
include both emotional and physical triggers of any kind. The authors present a case of
a male patient with nonconvulsive status epilepticus and symptoms suggesting takotsubo
syndrome. Echocardiographic examination revealed akinesis of the midsegment and apical
segment of the left ventricle, and impaired left ventricle function, but no coronary
artery disease was found on cardiac angiography. The clinical symptoms, and
echocardiographic and laboratory abnormalities, resolved gradually simultaneously with
neurological improvement.
Prevalence of femoral vein duplication: systematic review and metaanalysis
Authors: Sibuor William , Kipkorir Vincent , Cheruiyot Isaac , Gwala Fidel , Olabu Beda
Published: February 2022

Background: Duplication of the femoral vein is an important anatomical variation
of the venous anatomy which has been shown to have an impact on the diagnosis of deep
venous thrombosis by compression ultrasonography. The presence of duplication may result
in false negative findings while evaluating for deep venous thrombosis, with serious
consequences such as pulmonary embolism and death. This metaanalysis aims to determine
the pooled prevalence of duplicated femoral veins. Methods: A systematic search was
conducted through the major databases PubMed, Hinari, Embase and Medline to identify
studies eligible for inclusion. Appropriate data were extracted and pooled into a
random-effects metaanalysis using MetaXL software. The primary and secondary outcomes of
the study included the pooled prevalence of duplicated femoral veins and the prevalence
of bilaterally duplicated femoral veins, respectively. Results: A total of 11 studies (n
= 3,682 limbs) were included. The overall pooled prevalence of duplicated femoral veins
was 19.7% (95% CI 11–30). There was a significant difference in prevalence between
cadaveric studies (2%, 95% CI 1–4) and imaging studies (25%, 95% CI 17–34). Conclusion:
Duplication of the femoral vein is a common variation in the lower limbs. Routine
watch-out should be practiced especially when performing lower limb Doppler studies in
cases of deep venous thrombosis in order to avoid misdiagnosis and improve diagnostic
accuracy.

Smoking as a health problem: A priority-setting study in a tobacco industry dependent village
Authors: Putri Nuzulul Kusuma
Published: February 2022

Background and purpose: Indonesia is one of the most cigarette-friendly countries. The tobacco industry has gained economic dependence both nationally and domestically. Baureno Village in Indonesia has more than half of its population relied their life on the tobacco industry for long time. This study analysed how this high tobacco dependent community considered the smoking behaviour as one of prioritized health problems. Methods: This priority-setting study was conducted in quantitative and qualitative phases sequently. The quantitative data on smoking behaviour were collected on 251 households as the samples. This study captured the twelve healthy family indicators issued by The Indonesia Ministry of Health. Further, this data were brought into two different focus group discussions with community leaders and primary healthcare workers to understand how this community considered smoking as a health problem. Their prespective on prioritized health problem was revealed by performing a priority-setting analysis.Results: Smoking behaviour in cigarette producing areas is the impact of the economic dependence created by the tobacco industry. Ease of access and weak supervision of cigarette distribution in producing cigarette region caused smoking behaviour to be common place in this community group. Community considered smoking as a bottom priority of health problems, while health workers considered smoking as the second priority out of four identified health problems.Conclusion:. Community and health workers have a different prioritized health problems. Education to community should be enhanced to increase their awareness on the health impacts of tobacco smoking.

Background and purpose: Anxiety is generally found in primary health care patients with physical problems and are often not treated. This condition can affect the patient's sleep quality. The aim of this study was to determine the relationship between anxiety and sleep quality in patients attending Kecamatan Penjaringan Public Health Center (PHC), North Jakarta.Methods: This is a cross-sectional study of 434 patients attending the health care service of Kecamatan Penjaringan PHC, North Jakarta from August to October 2019. Data was collected with demographic and drug consumption questionnaire, Zung Self-rating Anxiety Scale (SAS) and Pittsburgh Sleep Quality Index (PSQI). Data analysis were including univariate and bivariate analysis conducted with SPSS 25.0.Results: There were 434 respondents aged 17-81 years old involved in the study, with an average age of 47.1 years, 72.4% of them were female, 56.2% with basic education, 54.8% were unemployed and 61.1% with low-income level. As high as 26.3% of the respondents were fallen into anxiety classification, including 19.4% mild anxiety, 5.5% moderate anxiety and 1.4% severe anxiety; while 53.5% of them reported poor sleep quality. Bivariate analysis showed a significant relationship between anxiety and sleep quality in patients attending Kecamatan Penjaringan PHC, North Jakarta (P<0.001). Patients with anxiety were 7.8 times (OR=7.819, 95%CI: 4.462-13.703) more likely to experience poor sleep quality than those without anxiety.Conclusion: There is a significant relationship between anxiety and sleep quality in patients attending Kecamatan Penjaringan PHC, North Jakarta. Detection of anxiety disorders and sleep quality should be considered as one essential part of patientsâ€™ care at PHC.
