Do stress and anxiety lead to belief in conspiracy theories?
Authors: Fox Nick , Williams Matt N
Published: April 2022

Conspiracies happen, and some conspiracy theories are warranted by evidence. Nevertheless, a non-trivial proportion of the public express belief in conspiracy theories that are not warranted by evidence. Psychological research has therefore investigated the motives that might lead someone to believe a conspiracy theory even where the available evidence for the theory is weak. Two potential causes that have been proposed in the literature and embedded in theorising are psychological stress and anxiety. Prior studies have provided some evidence that stress and anxiety are positively correlated with belief in conspiracy theories, but it remains unclear whether this apparent effect might be accounted for by plausible confounding variables. Furthermore, there have been few preregistered examinations of the proposed effects of stress and anxiety, rendering it unclear to what degree this proposition has yet been subjected to a severe test. In two preregistered cross-sectional survey studies, we tested whether higher perceived stress and anxiety significantly predicted belief in conspiracy theories while controlling for plausible confounding variables (age, education, subjective social status, and political orientation). We analysed data using structural equation models, allowing measurement error to be explicitly modelled and accounted for. In Study 1 (N =502), a cross-sectional survey of Australasian participants indicated that perceived stress and anxiety did not have significant estimated effects on belief in conspiracy theories. In Study 2 (N =1020), a cross-sectional survey of US participants showed a small significant positive effect of perceived stress, but not anxiety, on belief in conspiracy theories. The present results provide very tentative evidence for an effect of perceived stress on belief in conspiracy theories. However, it is increasingly evident that this effect, if it exists at all, is not large.
Of Germs and Culture; Parasite Stress as the Origin of Individualism-Collectivism
Authors: Shapouri Soheil
Published: April 2022

Among four proposed origins of individualism-collectivism, modernization theory, rice versus wheat theory, climato-economic theory, and pathogen stress theory, the latter has gained more attention in cross cultural and evolutionary psychology. Parasite stress theory gained even more popularity after the COVID pandemic as it makes a connection between infectious diseases and cultural orientations. But despite extensive research on parasite stress theory, it is not still clear what kind of infectious disease contribute more to the emergence of cultures, what are the possible mechanism through which pathogenic threat give rise to cultural systems, and how parasite stress might affect vertical vs. horizontal dimensions of individualism-collectivism. This review summarizes and integrates major findings of parasite stress theory related to individualism-collectivism and discusses future directions that researchers can take to answer remaining questions.
Bias in self-reports: An initial elevation phenomenon
Authors: Anvari Farid , Efendic Emir , Olsen Jerome , Arslan Ruben C. , Elson Malte , Schneider Iris K.
Published: April 2022

Researchers have long worried about a phenomenon where study participants give higher ratings on self-report scales the first time they take a survey compared to subsequent times, particularly for negative subjective experiences. Recent experimental evidence, using samples of U.S. college students, suggests that this initial elevation phenomenon is due to an upward bias in people’s initial responses. Such bias potentially undermines the validity of many research findings. However, more recent studies have found little evidence in support of the phenomenon. To investigate the robustness of the initial elevation phenomenon, we conducted the largest experiments to date in widely used online samples (N = 5,285 across 3 studies). We observed an initial elevation on self-reports of negative subjective experiences such as mood and mental and physical health symptoms. Our findings show that the threats to validity posed by the phenomenon are real and need to be reckoned with.
Automated Image Analysis for Studying Online Behaviour
Authors: Schwemmer Carsten , Unger Saïd , Heiberger Raphael
Published: April 2022

Digitization led to an enormous increase in the availability of visual data. As images are an important aspect of human communication, decades of social science research have analysed images, yet in mostly manual fashion with limited scaling capacities. In this work, we outline how recent advances in computer vision enable automated image analysis, allowing researchers to further unlock the potential of digital behavioural data. We introduce the field of computational social science and conduct a literature review of early studies using image recognition. We also highlight important aspects to be considered, such as computational demands and biases of computer vision models. Furthermore, in a case study, we examine the online behaviour of U.S. Members of Congress during the early COVID-19 pandemic in 2020. In particular, we focus on sharing images showing face masks as they are a crucial aspect of health and safety measures during the pandemic. Using Instagram data and models for detecting face masks, we find that temporal dynamics and party affiliation play a substantial role in the likelihood of sharing images of people wearing face masks: images with masks are more often posted after the introduction of mask mandates and Democratic party members are more likely to share images with masks. In addition, we find somewhat weaker to no differences regarding the age and gender of politicians.
Artysta zdradzony i zawiedziony. Portret Aleksandra Puszkina w Maskaradzie Jarosława Iwaszkiewicza
Authors: Olszewska Maria Jolanta
Published: April 2022

Jarosław Iwaszkiewicz's dramatic works, diversified in terms of theme and genre, by no means occupy a marginal place in his comprehensively perceived writing oeuvre. Three of Iwaszkiewicz's plays, linked by the artist's theme, deserve a special mention: Lato w Nohant, Maskarada and Wesele pana Balzaka. The subject of analysis in this article is the play “Masquerade”. That play focuses on the character of Alexander Pushkin and his complex relationship with the environment, which lead to the self-destruction of the poet, for whom the only salvation is death. In this play, Iwaszkiewicz connected the artistic theme with the question of subjectivity and identity.
Studia Palmyreńskie 14. Observations sur la topographie de Palmyre
Authors: Seigne Jacques
Published: April 2022

An important question in Palmyrene archaeology (and archaeology in general) is whether the relative, a fortiori absolute, chronology of monuments certain. There is a considerable number of inscriptions from the site, most of them well dated, but these are honorary dedications engraved a posteriori on existing monuments seldom allowing direct dating of specific buildings. For the most part, they provide a probable commissioning date rather than the date when the foundation stone was laid or the work completed. The dating of monuments through an architectural analysis and reassignment, if possible, of well-dated texts relating to their construction or inauguration is, therefore, a priority. The author’s observations made over long years spent in Palmyra, and the re-examination of old data, lets him propose new hypotheses concerning the chronology of certain structures and monumental complexes and, hence, to contribute to the discussion on the urban development of Palmyra.

Published: April 2022

BACKGROUND: Few reports exist on the characteristics and outcomes of persistent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in immunocompromised hosts. METHODS: A 49-year-old patient with granulomatosis with polyangiitis (GPA) and a renal transplant experienced multiple hospitalizations for coronavirus disease 2019 (COVID-19) pneumonia and relapses between October 2020 and February 2021. Careful chart review of medical history, hospitalizations, and microbiological testing including SARS-CoV-2 cycle threshold values, therapies, and imaging was undertaken. SARS-CoV-2 genome sequencing was performed in five viral samples to distinguish persistent infection from re-infection with a different strain. RESULTS: Sequencing confirmed that all samples tested were from the same viral lineage, indicating a long-term, persistent infection rather than re-infection with a new strain. The patient ultimately stabilized after two courses of remdesivir plus dexamethasone, replacement intravenous immunoglobulin, and bamlanivimab. Rituximab maintenance therapy for vasculitis remains on hold. CONCLUSIONS: SARS-CoV-2 may persist for several months in immunocompromised hosts and may go unrecognized as an ongoing active infection. More studies are needed to determine how to optimize COVID-19 treatment in this vulnerable population.

“Voluntary Return” without Civil Society?
Authors: Schweitzer Reinhard
Published: April 2022

This article looks at the implementation of so-called “assisted voluntary return” policies in Austria and Britain, where state agencies have recently replaced nongovernmental organizations as providers of return counseling. To better understand how such a shift affects the in/voluntariness of return, I identify three dimensions along which the “quality” of voluntariness can be assessed and relate them to concrete aspects of return counseling practice: absence of coercion; availability of acceptable alternatives; and access to adequate and trusted information. Based on original qualitative data, I show that even within an overall restrictive and oppressive regime, return counselors can make room for voluntariness by upholding ethical and procedural standards—if they retain substantial independence from the government.

Authors:   International Institute for Democracy and Electoral Assistance (International IDEA)
Published: April 2022

When it became known in early 2020 that Covid-19 was becoming a global pandemic, it also became clear that governmental responses to the pandemic would have significant effects on democracy and human rights. With two years of data from International IDEA’s Global Monitor of Covid-19’s Impact on Democracy and Human Rights, we can take stock of what has happened and in which areas the events align with or differ from our expectations about how a pandemic might affect these vital areas of public life. This report examines the effects of the pandemic responses in six broad areas: (1) emergency legal responses and civil liberties, (2) freedom of movement, association, and assembly, (3) freedom of expression and media integrity, (4) privacy rights and contact tracing applications, (5) women’s rights and minority rights, and (6) vaccination and fundamental rights. In each of the sections, the report describes the global trends in each of these areas, highlights cases that illustrate both positive and negative examples, and considers what the upcoming challenges will be.

Published: April 2022

The Dye-Sensitized Solar Cell (DSSC) is still inefficient. Because low efficiency is caused by electron recombination, this study reduced it by the electrodeposition of Ag metal against TiO2. XRD was used to determine the crystal structure, size, and effect of Ag electrodeposition on TiO2. SEM-EDS was used to investigate the surface morphology and the presence of Ag metal in the TiO2-Ag layer. Anthocyanins were used as dyes. To improve thermal stability and achieve a bathochromic effect, the anthocyanin used was co-pigmented with salicylic acid. The anthocyanin extract used in this study was obtained from the red grape peel (Vitis Vinifera), jengkol peel (Pithecellobium jiringa), senduduk fruit (Melastoma malabathricum L), and mangosteen peel (Garcinia Mangostana L). The dyes were identified using UV-Vis and FTIR. The electrical properties of the resulting DSSC were measured using a multi-meter. According to this study, the electrodeposition of Ag on the TiO2 layer could improve DSSC efficiency. The highest efficiency was achieved in DSSC with TiO2-Ag and co-pigmented dye using mangosteen peel as the dye source

Authors: E. Julianti Tursino , Gusdinar T. , Damayanti S.
Published: April 2022

Several substrates have been used for the determination of protease activity of pancreatin. However, there are still weaknesses of substrates such as insolubility, preparation, and a number of reagents used. Therefore, the alternative finding for the substrate for protease activity assay of pancreatin is still openly investigated. This study was aimed to isolate and characterize C-phycocyanin (CPC) from Spirulina platensis and its application as a substrate in protease activity assay. The research includes isolation, purification and characterization of CPC, the interaction of CPC with pancreatin, determining the relationship between initial rate of reaction and protease activity and study of pancreatin protease kinetics. From the experimental results, the ATPS-D fraction with a CPC content of 138.5 ± 0.06 μg/mL and a CPC purity of 0.74 ± 0.00 was used as a substrate solution. The results of the interaction of CPC with pancreatin showed a decrease in CPC content in the incubation time used. The relationship between the initial rate of reaction and protease activity (5 – 30 IU/mL) showed a linear curve, especially at an incubation time of 5 -30 minutes with R2 > 0.9. Enzyme kinetics study showed that the Vmax and Km values for reaction incubation time of 10, 20, 30 minutes were 2.59 g/mL/minute and 91.66 g/mL; 1.47 g/mL/minute and 70.86 g/mL; 1.31 g/mL/minute and 79.22 g/mL/minute, respectively. In conclusion, CPC can be used as a new substrate candidate for the determination of pancreatin protease activity.
THE PORE FORMATION AND DOPING PROCESS ON THE SYNTHESIS OF NITROGEN-DOPED TITANIA THROUGH SOL-GEL METHOD
Authors: C. Kusumawardani
Published: April 2022

The mesoporous nitrogen-doped titania (N-doped TiO2) has been synthesized through a one-step sol-gel method using dodecylamine as pore template and nitrogen source, which were performed with and without reflux. The role of aging time toward pore formation and doping process was also studied by applying 0 and 72 hours of aging time to the resulting solution after the hydrolysis step. The resulting material was characterized using X-Ray Diffraction (XRD), N2 Gas Sorption Analyzer (GSA), and X-ray Photoelectron Spectroscopy (XPS). The result showed that the reflux process played an important role in the doping process, where there is no nitrogen found in the material synthesized without reflux. The aging process also influenced the doping process, where the structure rearrangement is occurred increasing the nitrogen amount that substitutes the oxygen site in the TiO2 lattice, resulting in higher nitrogen content in the TiO2. The reflux process and aging process do not directly affect the pore formation of the TiO2 but applying both processes in the synthesis resulted in a material with a higher specific surface area and a more homogenous mesoporous size and structure

The disintegration of the amide link, causing L-Asparaginase catalyzes the hydrolysis process of L-Asparagine into ammonia and aspartic acid. The purposes of this study were to determine the optimal conditions for enzyme production and enzymatic activity, including their potential as a new anti-dengue of L-asparaginase from Klebsiella sp. The Nessler method used a UV-Visible spectrophotometer to determine the L-asparaginase activity by measuring ammonia levels produced by L-asparaginase catalysis. The ideal fermentation period was at the 48th hour, and the optimal substrate concentration was 10 g/L with an activity value of 49.572 U/mL, and the optimal FeCl2 concentration was 0.5 g/L with an activity value of 60.1183 U/mL, and protein content of 0.1878 mg/mL. The optimum conditions for L-asparaginase, which has an activity value of 61.1182 U/mL, were observed at pH 8 and 37 °C. The optimum cofactor concentration of FeCl2 was 0.5 mM, which resulted in an activity value of 106.5046 U/mL. Both the inhibition percentage and CC50 value were 80% and 167.15 μg/mL respectively, showing that the L-asparaginase has a high antidengue potential.

Published: April 2022

In order to increase surface functional groups and to leach out unbound metal oxide particles from an iron oxide impregnated carbon matrix prepared from the roots of Chrysopogon zizanioides, treatment with 30% hydrogen peroxide was attempted in the present work. Surface chemical properties of the new peroxide treated magnetic carbon were evaluated along with FTIR, SEM, EDAX, VSM, DLS, X-ray diffraction and thermal analysis. Ability of this oxidized carbon to remove cationic methylene blue (MB) and rhodamine B (RB) dyes from water is assessed by studying the adsorption isotherms and kinetics. In addition, the carbon was also able to activate persulphate in the sun light assisted degradation of these dyes with high velocities. The matrix was able to retain its ability after three cycles of degradations.

The SiO2 glasses embedded with Cr3+ ions are notable for solid state optical resource, which are useful in various opto-electronic and semiconducting applications. However, the available thermoluminescent resource, which include different electronic and semiconducting materials, need some refinement in their structure, luminescence, and electronic properties towards development of advanced glass resource. In this vision, CrxCa(10-x)Al30Si60 glassy materials have planned for synthesis and testing. The GT, and GC phase transition points, and thermal stability (~1.2639) of test samples are identified. Structural vibrations are identified with the help of FT-IR spectra. The order of electrical conductivity (~1.657x10-4 ohm-1 cm-1), and A.E. (~0.3669 eV) of test samples reveal their electrical strength. The symmetry (~ 0.576%) factor, frequency (1.1172 X 1020 S -1) factor, and A.E. (0.682 eV) of the test samples are recorded under 30 kGy irradiation. Overall, the results, which include structure, electrical and luminescence of the test samples suggest the materials might be useful electrically conductive and thermal stimulated light resource.

Der weite Weg zur Meritokratie: Strukturelle Hürden für junge Wissenschaftler*innen
Authors: Mann Martin
Published: April 2022

Das Wissenschaftssystem ist darauf angelegt, die Grenzen des Wissens zu verschieben. Diesem Anspruch kann es nur entsprechen, wenn es möglichst viele begabte, ambitionierte und qualifizierte Wissenschaftler*innen beschäftigt. Die finanzielle Grundlage hierfür wurde zwar durch den Drittmittelaufwachs der vergangenen Jahre geschaffen. Jedoch ist es nicht gelungen, das akademische System so zu öffnen, dass einer möglichst großen Vielfalt von Menschen die Teilhabe am Wettbewerb um die besten Ideen erlaubt ist. Im folgenden Beitrag wird anhand der Erkenntnisse der jüngeren Wissenschaftsforschung gezeigt, dass das Wissenschaftssystem dem eigenen Anspruch an Meritokratie nicht gerecht wird. Außerdem werden Lösungsansätze zur Beseitigung der Einstiegs- und Aufstiegshürden aufgezeigt.
CmP signaling network unveils novel biomarkers for triple negative breast cancer in African American women

Published: April 2022

Breast cancer is the most diagnosed cancer worldwide and remains the second leading cause of cancer death. While breast cancer mortality has steadily declined over the past decades through medical advances, an alarming disparity in breast cancer mortality has emerged between African American women (AAW) and Caucasian American women (CAW). New evidence suggests more aggressive behavior of triple-negative breast cancer (TNBC) in AAW may contribute to racial differences in tumor biology and mortality. Progesterone (PRG) can exert its cellular effects through either its classic, non-classic, or combined responses through binding to either classic nuclear PRG receptors (nPRs) or non-classic membrane PRG receptors (mPRs), warranting both pathways equally important in PRG-mediated signaling. In our previous report, we demonstrated that the CCM signaling complex (CSC) consisting of CCM1, CCM2, and CCM3 can couple both nPRs and mPRs signaling cascades to form a CSC-mPRs-PRG-nPRs (CmPn) signaling network in nPR positive(+) breast cancer cells. In this report, we furthered our research by establishing the CSC-mPRs-PRG (CmP) signaling network in nPR(-) breast cancer cells, demonstrating that a common core mechanism exists, regardless of nPR(+⁣/⁣-) status. This is the first report stating that inducible expression patterns exist between CCMs and major mPRs in TNBC cells. Furthermore, we firstly show mPRs in TNBC cells are localized in the nucleus and participate in nucleocytoplasmic shuttling in a coordinately synchronized fashion with CCMs under steroid actions, following the same cellular distribution as other well-defined steroid hormone receptors. Finally, for the first time, we deconvoluted the CmP signalosome by using systems biology and TNBC clinical data, which helped us understand key factors within the CmP network and identify 6 specific biomarkers with potential clinical applications associated with AAW-TNBC tumorigenesis. These novel biomarkers could have immediate clinical implications to dramatically improve health disparities among AAW-TNBCs.

BACKGROUND: The recently emerged SARS-CoV-2 caused a global pandemic since the last two years. The urgent need to control the spread of the virus and rapid application of the suitable health measures raised the importance of available, rapid, and accurate diagnostic approaches. OBJECTIVE: The purpose of this study is to describe a rapid in-house optimized ELISA based on the expression of the receptor binding domain (RBD) of the SARS-CoV-2 spike protein in a prokaryotic system. METHODS: We show the expression of the 30 kDa recombinant SARS-CoV-2 RBD-6×His in four different E. coli strains (at 28∘C using 0.25mM IPTG) including the expression strain E. coli BL21 (DE3) Rosetta Gami. SARS-CoV-2 rRBD-6×His protein was purified, refolded, and used as an antigen coat to assess antibody response in human sera against SARS-CoV-2 infection. RESULTS: The assessment was carried out using a total of 155 human sero-positive and negative SARS-CoV-2 antibodies. The ELISA showed 69.5% sensitivity, 88% specificity, 78.5% agreement, a positive predictive value (PPV) of 92.3%, and a negative predictive value of 56.5%. Moreover, the optical density (OD) values of positive samples significantly correlated with the commercial kit titers. CONCLUSIONS: Specific human antibodies against SARS-CoV-2 spike protein were detected by rapid in-house ELISA in sera of human COVID-19-infected patients. The availability of this in-house ELISA protocol would be valuable for various diagnostic and epidemiological applications, particularly in developing countries. Future studies are planned for the use of the generated SARS-CoV-2 rRBD-6×His protein in vaccine development and other diagnostic applications.
Feature matching for 3D AR: Review from handcrafted methods to deep learning
Authors: Halmaoui Houssam , Haqiq Abdelkrim
Published: April 2022

3D augmented reality (AR) has a photometric aspect of 3D rendering and a geometric aspect of camera tracking. In this paper, we will discuss the second aspect, which involves feature matching for stable 3D object insertion. We present the different types of image matching approaches, starting from handcrafted feature algorithms and machine learning methods, to recent deep learning approaches using various types of CNN architectures, and more modern end-to-end models. A comparison of these methods is performed according to criteria of real time and accuracy, to allow the choice of the most relevant methods for a 3D AR system.
Hereditary Renal Cell Carcinoma
Authors: Dawsey Scott J. , Gupta Shilpa
Published: April 2022

BACKGROUND:

Hereditary renal cell carcinoma (RCC) is a complex and rapidly evolving topic as there is a growing body of literature regarding inherited syndromes and mutations associated with an increased risk of RCC.

OBJECTIVES:

We sought to systematically review 13 hereditary syndromes associated with RCC; von Hippel-Lindau Disease associated RCC (VHLRCC), BAP-1 associated clear cell RCC (BAPccRCC), Familial non-von Hippel Lindau clear cell RCC (FccRCC), Tuberous Sclerosis Complex associated RCC (TSCRCC), Birt-Hogg-Dub[Formula: see text] Syndrome associated RCC (BHDRCC), PTEN Hamartoma Tumor Syndrome associated RCC (PHTSRCC), Microphthalmia-associated Transcription Family translocation RCC (MiTFtRCC), RCC with Chromosome 6p Amplification (TFEBRCC), Autosomal Dominant Polycystic Kidney Disease associated RCC (ADPKDRCC), Hereditary Leiomyomatosis associated RCC (HLRCC), Succinate Dehydrogenase RCC (SDHRCC), Hereditary Papillary RCC (HPRCC), and ALK-Rearrangement RCC (ALKRCC).

RESULTS:

Hereditary RCC is generally associated with an early age of onset, multifocal and/or bilateral lesions, and aggressive disease course. VHLRCC, BAPccRCC, FccRCC, and certain mutations resulting in SDHRCC are associated with clear cell RCC (ccRCC). HPRCC is associated with Type 1 papillary RCC. HLRCC is associated with type 2 papillary RCC. BHDRCC is associated with Chromophobe RCC. TSCRCC, PHTSRCC, MiTFtRCC, TFEBRCC, ADPKDRCC, certain SDHRCC and ALKRCC have variable histology.

CONCLUSIONS:

There has been tremendous advancement in our understanding of the pathophysiology of hereditary RCC. Ongoing research will refine our understanding of hereditary RCC and its therapeutic targets.
Regression analysis based decision support system with relationship extraction
Authors: Aravinth S.S. , Srithar S. , Senthilkumar M. , Senthilkumar J.
Published: April 2022

Regression analysis is a widely used statistical technique for estimating the relationship between two variables. These two variables are called independent and dependent variables. The regression techniques are classified into two broad categories such as linear and logistic regression. Based on the input dataset, these two techniques are chosen and implemented. Many organizations and institutions are trying to use the decision support system for extracting the relationship between the employees’ salaries based on the target achieved and the years of experience. In this paper, the relationship extraction between two variables is analysed and studied. Based on the Experience, the salary of employees is predicted. Here the model extracts the relationship among the variables first, next to that forecasting of new observations is carried out. In this phased approach, the data pre-processing is carried out to clean the noise on the dataset. Followed by, fitting the model to train the train set and testing test. The third phase predicts the results based on the two variables to draw some observations. As a final step, visualization is employed on training and testing datasets. To implement this proposed work, the employee database from an organization is considered. This dataset contains 115 technical and non-technical staff details with their profile information.
On continuity of distribution function and decreasing rearrangement
Authors: Bhat M. Ashraf , Kosuru G. Sankara Raju
Published: April 2022

Given a measure space (Ω,Σ,μ), the distribution function μf⁢(ν)=μ⁢({t∈Ω:|f⁢(t)|>ν}) where ν⩾0 and the decreasing rearrangement f*⁢(z)=inf⁡{ν⩾0:μf⁢(ν)⩽z}, where z⩾0 and by convention i⁢n⁢f⁢{∅}=∞, of a measurable function f are known to be right continuous functions. However, these functions need not be left continuous. The purpose of this paper is to investigate the conditions under which these functions are continuous. Under the assumption that μ⁢({t∈Ω:|f⁢(t)|>0})<∞, we provide a necessary and sufficient condition for the function μf to be continuous at ν>0. Using the same we provide a similar result for the continuity of decreasing rearrangement f* of the function f.

Published: April 2022

BACKGROUND: Worldwide, approximately 350 million people are currently employed in the construction industry. OBJECTIVE: To determine the prevalence, pain characteristics, and associated risk factors for musculoskeletal disorders (MSDs) among construction workers in Pakistan. METHODS: This study was a cross-sectional survey conducted from February to August 2019 among 666 construction workers. The data were collected using a questionnaire consisting of 4 sections: demographic information, a numerical pain intensity rating scale, a Nordic questionnaire to report prevalence, and pain characteristics. SPSS was used for data entry and analysis. RESULTS: The mean age of the construction workers was 34.49 years. Participants who reported pain were 397 out of 666 and 269 were those who reported no pain. The 12-month prevalence of pain among construction workers in more than one body area was 89% (n = 591) and the 7-day prevalence was 52% (n = 343); lower back pain was the most common type of pain with a 12-month prevalence of 27% (n = 180) and a 7-day prevalence of 17% (n = 112). Regarding the characteristics of the pain, 26% (173) of the workers suffered pain occasionally, 27% (180) participants had pain for≤2 hours per day, and 32.9% (219) had dull pain. Moreover, a significant relationship was found (p < 0.05) between MSDs and age, lifestyle, work experience, smoking habits, and absence from work. CONCLUSION: Musculoskeletal pain is highly prevalent, with lower back pain being the most commonly reported type. Absence from work and disability in performing normal daily activities have been reported as consequences of musculoskeletal pain. Moreover, this study underscores the importance of targeted preventive healthcare measures for construction workers.
