Background
Cyberchondria is characterized by repeated and compulsive online searches for health information, resulting in increased health anxiety and distress. It has been conceptualized as a multidimensional construct fueled by both anxiety and compulsivity-related factors and described as a “transdiagnostic compulsive behavioral syndrome,” which is associated with health anxiety, problematic internet use, and obsessive-compulsive symptoms. Cyberchondria is not included in the International Classification of Diseases 11th Revision or the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and its defining features, etiological mechanisms, and assessment continue to be debated.

Objective
This study aims to investigate changes in the severity of cyberchondria during the COVID-19 pandemic and identify the predictors of cyberchondria at this time.

Methods
Data collection started on May 4, 2020, and ended on June 10, 2020, which corresponds to the first wave of the COVID-19 pandemic in Europe. At the time the study took place, French-speaking countries in Europe (France, Switzerland, Belgium, and Luxembourg) all implemented lockdown or semilockdown measures. The survey consisted of a questionnaire collecting demographic information (sex, age, education level, and country of residence) and information about socioeconomic circumstances during the first lockdown (eg, economic situation, housing, and employment status) and was followed by several instruments assessing various psychological and health-related constructs. Inclusion criteria for the study were being at least 18 years of age and having a good understanding of French. Self-report data were collected from 725 participants aged 18-77 (mean 33.29, SD 12.88) years, with females constituting the majority (416/725, 57.4%).

Results
The results showed that the COVID-19 pandemic affected various facets of cyberchondria: cyberchondria-related distress and compulsion increased (distress z=–3.651, P<.001; compulsion z=–5.697, P<.001), whereas the reassurance facet of cyberchondria decreased (z=–6.680, P<.001). In addition, COVID-19–related fears and health anxiety emerged as the strongest predictors of cyberchondria-related distress and interference with functioning during the pandemic.

Conclusions
These findings provide evidence of the impact of the COVID-19 pandemic on cyberchondria and identify factors that should be considered in efforts to prevent and manage cyberchondria at times of public health crises. In addition, they are consistent with a theoretical model of cyberchondria during the COVID-19 pandemic proposed in 2020. These findings have implications for the conceptualization and future assessment of cyberchondria.

ABSTRACT

Objectives
To determine patient perceptions and attitudes regarding posttreatment changes at least 2 years after completion of orthodontic treatment.

Materials and Methods
A total of 125 patients (75 females, 50 males, aged 22.93 ± 2.98 years) were enrolled at least 2 years after debonding. Participants had either vacuum-formed retainers (VFRs) or bonded retainers (BRs). Posttreatment changes were evaluated digitally by comparing tooth positions at debonding and at least 2 years after debonding. A questionnaire was used to assess patient attitudes. Retainer usage, awareness of relapse, satisfaction with their current occlusion, and whether posttreatment changes were severe enough for them to consider retreatment were investigated.

Results
All patients showed some posttreatment changes in irregularity. Only 74% of patients wearing VFRs and 47.1% of patients wearing BRs were aware of posttreatment changes. Patients were more likely to notice posttreatment changes if there was an increase in mandibular irregularity of 1–3 mm. Awareness of posttreatment changes in the upper arch was higher in both groups. The majority of participants were satisfied with the results even if they noticed some minor posttreatment changes (VFR, 69.4%; BR, 76.5%). Dissatisfaction with posttreatment changes did not necessarily mean that a patient wanted retreatment.

Conclusions
A total of 26% of patients wearing VFRs and 52.9% of patients wearing BRs were unaware of posttreatment changes. Approximately half of the patients who noticed posttreatment changes were still satisfied with the result 2 years after debonding. Even patients dissatisfied with the effect of posttreatment changes do not necessarily want retreatment.

Abstract
Perennial species in a mountain grassland where there is high oligotrophy need support for good development. Soil nutrients, either in large amounts or in small quantities, are the driving force in the management of communities of microorganisms that compete and proliferate nutritionally. The symbiosis between vascular plants and fungi in the soil is extraordinary support for perennial species. The roots of the two dominant species in the meadow were harvested after the moment of flowering. They were prepared and stained according to standard methods for evaluating the colonization process. And the process was quantified with the MycoPatt tool. For both species, differentiated fertilization induces similar changes in fungal strategy. But at the level of the formation of the specific structures of the fungi as well as in their development in the cells of the host plants the differences are visible. Maps exported from the MycoPatt tool can be analysed based on strategies or punctually based on color distribution. One can analyse the distribution of each colour (hyphae-blue, arbuscules-red, vesicles-green) as well as the white areas that are represented by parts of the root where the plant does not allow the development of fungi. The use of the MycoPatt tool simplifies the understanding of the symbiotic process and in addition to the multitude of exported indices, it also provides colonization maps that easily show the changes induced by fertilization on the host plants. Thus, being able to predict the best management practice of the whole ecosystem, to sustainably develop grasslands.

Characterization Of Soil For Road Shoulders Mixed With Reclaimed Asphalt Pavement Waste
Authors: SABERİ Saber Shah , MOHAMED Azman 
Published: March 2023

The use of recovered asphalt pavement can reduce the amount of new bitumen and aggregates used in pavement construction and rehabilitation (RAP). RAP is a waste product that results from the removal of an old or damaged pavement surface. Although it has been used since the 1970s, and numerous recommendations for using RAP in the new mixture have been made, there are only a few research available. Because the materials used are recycled, it is also cost-effective and environmentally friendly. The purpose of this study is to characterize soil that has been blended with reclaimed asphalt pavement (RAP) for use on the local road shoulder. RAP is one of the rehabilitation procedures used to repair a deteriorated surface by removing the upper pavement and replacing it with new pavement. According to earlier study, mixing dirt with different materials improves the finding. The goals of this study are to establish the material qualities of soil and RAP, determine the optimum moisture content of material and degree of compaction for road shoulders, and determine the appropriate mix proportion of soil and RAP for road shoulders using the California Bearing Ratio (CBR) test. The Atterberg limit, liquid limit, and plastic limit for soil were evaluated on a sample of soil and RAP. For soil and RAP, a sieve analysis was performed. Compaction tests for soil and RAP were carried out with a mixture of 10S, 2S8RAP, 4S6RAP, 6S4RAP, 8S2RAP, and 10RAP, as well as CBR tests for soil and RAP. . According to the results of the laboratory test, 20% of RAP (8S2RAP) had a better-mixed proportion for the road shoulder. As a result, repurposed materials like RAP can be used as road shoulder material.

<p><em>A key challenge to real-world policy making is determining how to match policy goals with the means available to implement them. This match is problematic for several reasons, not the least of which is the lack of </em> <em>conceptual clarity surrounding how targets should be set for policy goals and how exactly policy tools should be calibrated to meet them. These subjects have been examined by a number of scholars, but </em> <em>their insights have not been synthesized into a common framework, applicable in practice.

Purpose: The severe course of COVID-19 in individuals with chronic diseases has led to concerns in the management of rheumatic diseases during the pandemic therefore we aimed to define the factors associated with the frequency and severity of COVID-19 in patients with axial spondyloarthritis (axSpa) in this study.
Materials-Methods: Patients with axSpa who were followed up in three tertiary hospitals and used their treatment regularly for at least six months were included. We assessed the relationship between axSpa associated variables such as disease duration time, radiological severity, treatment and COVID-19 outcomes.
Results: A total of 833 patients with a mean disease duration of 109 months were analyzed; 64.5% had ankylosing spondylitis, 35.5% had non-radiographic axSpa diagnosis, and 59.4% of patients were treated with biologic agent . The frequency of COVID-19 was 23% (n: 192); only five pateints (0.5%) had a history of intensive care unit. Advanced age, hypertension (HT), and diabetes mellitus (DM) were found to be significantly more common in those with involvement in high resolution computed tomography (HRCT) (p:0.02, p:0.01, and p
<div>Switching from Payroll Taxes to Corporate&nbsp;Income Taxes: Firms’
Employment and Wages after the 2012 Colombian Tax Reform</div>
Authors: Bernal Raquel , Meléndez Marcela , Eslava Marcela , Pinzón Alvaro 
Published: March 2023

The 2012 Colombian tax reform reduced payroll taxes and employer contributions to
health insurance by 13.5 percent, while also increasing corporate income taxes and
leaving untouched the benefits to workers financed through these taxes. Shifting
taxation from formal employment to other business activities is a policy recipe under
heated discussion in Latin America. The reform offers an ideal laboratory for studying
empirically the potential distortions against formal employment associated with payroll
taxes in contrast to other taxes on firms. We analyze the impact of the reform on
employment and wages using monthly firm-level data on all formal employment in nonpublic
firms in the country and a difference-in-differences approach that takes advantage of
the fact that a few sectors were exempt from the 2012 tax reform. We find a positive
average effect of 4.3 percent on employment and 2.7 percent on average firm wages, for
the average firm. The employment effect is found only for micro and small firms, whereas
the bulk of the employment is concentrated in medium and large firms, which show no
significant effect. According to these estimates, about 145,000 new jobs were created
between January and May of 2015 by virtue of the reform. These results are generally
supportive of efforts to reduce payroll taxes, though our findings on employment are
less robust than those on wages, and large firms do not seem to have benefitted. The
apparent lack of effect for medium and large employers is also a source of concern. We
speculate that it may be due to these firms’ being more sensitive to the increase in
corporate taxation that financed the reduction in payroll taxes, but lack of access to
the relevant data prevents us from offering solid evidence regarding this
hypothesis. JEL Codes: H25, H32
Morphological changes in the liver of rats after administration of chlorpromazine, depending on the dose and duration of administration
Authors: Bailo O. V. , Rykalo N. A. 
Published: March 2023

Chlorpromazine (CPZ) remains a widely used drug in psychiatric practice today. The drug has a hepatotoxic effect, but the possible mechanisms of this side effect have not yet been fully elucidated. The aim of the study was to determine morphological changes in rat liver tissue under chronic toxic effects of chlorpromazine, depending on the dose and duration of its administration. The study was conducted on 60 sexually mature male rats. CPP was administered intragastrically at different doses (3.5, 7.0, 14.0 and 21.0 mg/kg) for 30 and 60 days. The material was fixed in a 10 % solution of neutral formalin (pH 7.2-7.4) for 24-48 hours, then passed through alcohols of increasing concentration and embedded in paraffin. Serial sections (6-7 µm thick) were prepared from the paraffin blocks and stained with hematoxylin-eosin and picrofuchsin by Van Gieson to determine the degree of fibrotic changes in liver tissue, as well as with Giemsa III to detect fatty degeneration of hepatocytes. The microscopic structure of the hepatic parenchyma was studied using an OLIMPUS BX41 light microscope at 100, 200 and 400x magnification. Morphometric parameters of structural changes were determined using an ocular grid and Image Tulsa 3.6 software. The data were statistically processed by descriptive statistics using the Microsoft Office Excel 2010 spreadsheet processor. When CPZ was administered in different doses and duration, pathological changes of varying severity developed in the liver tissue of rats. In the liver tissue, signs of intracellular and intra-tubular cholestasis are found mainly in the central lobes, accompanied by focal desquamation and proliferation of the biliary epithelium, formation of small-focal, less frequently zonal necrosis of hepatocytes, inflammatory infiltration of portal tracts with its spread to the interlobular stroma and parenchyma. Mitotically active binucleated hepatocytes are the key to the reparative process. Periductal fibrosis develops in the portal sections, marginal proliferation of the bile ducts, hepatocytes with signs of granular and/or fatty dystrophy are noted. In the central veins and vessels of the portal areas, moderate initial sclerotic changes were found, signs of their capillarisation in sinusoids, and the endothelium of the vessels had focal destructive changes. In all portal zones, proliferation of bile ducts and formation of bile pseudo-ducts were observed. Thus, the analysis of the morphometric study data showed that within 60 days of CPZ administration there is a significant increase in the relative volume of connective tissue and stromal-parenchymal index due to a significant decrease in the volume of hepatocytes.

This study aims to optimize the application of SBAR communication during handovers between nursing shifts. This research method is a case study with a situation analysis. The results showed that the application of SBAR communication was not optimal when handing over patients between nursing shifts. Innovations are developed by making additional recommendations for SBAR SOPs and monitoring and evaluation drafts referring to the literature. A trial of money filling can be carried out. In conclusion, it is necessary to have a supervisor (Karu) whose function is to direct nurses, especially in the implementation of the handover, so that the nurse will carry out the weigh-in following the direction of the head of the room and the SOP that applies in the room regarding the implementation of the handover.
