Authors: Li Chenghao , Jia Xiujie , Wu Shuangshuang , Li Fangyi , Wang Xing , Ren Yuan
Published: November 2022

Recently, wet blast cleaning of paint has attracted attention in remanufacturing processes, owing to its high efficiency and environmental friendliness. However, studies of removal mechanism have rarely considered the properties of abrasive particles; thus, there is insufficient theoretical guidance on the process optimization, resulting in energy waste during the cleaning process. Therefore, the mechanism in wet blast cleaning of paint was researched in this study, which focused on the effects of abrasive particle shape and size on mechanism. The results indicate that the removal mechanisms of angular and spherical abrasive particles are significantly different, and that of angular abrasive particles is not affected by the particle size, whereas that of spherical abrasive particles is significantly affected. The main removal mechanism for all angular abrasive particles is brittle fracture caused by large impact stresses. For large spherical abrasive particles (≥60-mesh), the main mechanism is brittle fracture due to the intersection of longitudinal-through fatigue cracks and interface cracks, and for small spherical abrasive particles (≤80-mesh), it is brittle fracture due to fatigue cracks and impact cracks. This study provides good insight into abrasive particles and serves as a good basis for exploring the process parameters for wet blast cleaning.
What Are People Willing to Pay for Social Sustainability? A Choice Experiment among Dutch Consumers

Published: November 2022

A relatively large number of studies has shown that consumers are willing to pay more for products that are certified as being environmentally or socially responsible, but most of these studies focus on the willingness to pay (WTP) for environmental benefits, while insights into the WTP for social benefits are limited. More research in this area will shed light on consumer choices and help policymakers to better direct the food industry toward social sustainability. In this paper, we carry out a Discrete Choice Experiment among Dutch consumers to measure consumer WTP for five social sustainability benefits; (1) no child labor; (2) liveable wage and safe working environment; (3) project for the education of workers; (4) equal wages for men and women; and (5) freedom to join a trade union. The novelty of our research in comparison with previous studies is that we aim to differentiate the WTP for various social standards instead of estimating an overall WTP for fair-trade labels. In addition to average price premiums per social standard, our latent class models also give insight into heterogeneity in WTP, or more specifically, stated price premiums by different groups (or market segments) in society. The results suggest that substantial price premiums for social sustainability benefits may exist, which currently are not reflected in food prices. Including price premiums for market products that fully incorporate societal costs of those products, so-called true prices or shadow prices, will decrease consumer demand for less-sustainable products and will lead to a fairer and more sustainable economic system. Our results also show that the price premiums may vary substantially between the various categories of social sustainability benefits and across products and market segments. Further research on assessing the motivations behind consumer choices for more-sustainable products is crucial here, especially for campaigns aimed at enhancing their market shares.

Published: November 2022

With the rapid development of deep learning, pavement crack detection has started to shift from traditional manual visual inspection to automated detection; however, automatic detection is still a challenge due to many complex interference conditions on pavements. To solve the problem of shadow interference in pavement crack detection, this paper proposes an improved shadow generation network, named Texture Self-Supervised CycleGAN (CycleGAN-TSS), which can improve the effect of generation and can be used to augment the band of shadowed images of pavement cracks. We selected various images from three public datasets, namely Crack500, cracktree200, and CFD, to create shadowed pavement-crack images and fed them into CycleGAN-TSS for training to inspect the generation effect of the network. To verify the effect of the proposed method on crack segmentation with shadow interference, the segmentation results of the augmented dataset were compared with those of the original dataset, using the U-Net. The results show that the segmentation network achieved a higher crack recognition accuracy after the augmented dataset was used for training. Our method, which involves generating shadowed images to augment the dataset and putting them into the training network, can effectively improve the anti-shadow interference ability of the crack segmentation network. The research in this paper also provides a feasible method for improving detection accuracy under other interference conditions in future pavement recognition work.

The objective of this research was to study the differences in the enrichment and transport capacity of heavy metal chromium in farmland soil by different maize cultivars, and it is of great significance to screen out the maize varieties that meet the food safety standards and repair the heavy metal chromium in farmland soil. To complete the experiment, under the conditions of field experiments, 72 maize cultivars were selected to study the growth of maize in chromium-polluted arable land and the differences in Cr accumulation and transshipment of different maize cultivars. From the experiment, we found that among 72 maize varieties, 49 of them, accounting for 68.06% of the total, had kernel chromium content lower than the China kernel limit standard value of 1.0 mg kg−1. There were significant differences in Cr content in the kernels, stems, leaves and roots of all cultivars, with Cr content in root > stems > kernels. The contents of Cr in roots and stems and kernels were 4.06–93.09 mg kg−1 and 5.54–24.13 mg kg−1 and 0.46–2.61 mg kg−1, respectively, and the coefficients of variation were 51.21%, 36.36% and 46.11%. By cluster analysis, maize varieties were divided into five groups according to kernel chromium content, and the maize varieties were also divided into three categories according to the content of chromium in stem and leaf. At the same time, we found that the low accumulation of kernel, high accumulation of stem and leaf, seven varieties: Nongyu662, HongyuNO.9, Wankenyu125, Shuxinyu228, Kewei702, Liyu16, JinchengNo.6. The enrichment coefficients (BCF) of each maize cultivar ranged from 0.026 to 0.194, the transport coefficients TF (kernel/stem) and TF (stem/root) were between 0.028 and 0.064, and 0.064 and 0.864, and the enrichment coefficient and transport coefficient were less than 1. In the end, according to the comprehensive evaluation of the maize growth status, kernel Cr content, enrichment coefficient, transport coefficient and other indicators, it is believed that Nongyu662, HongyuNo.9, Wankenyu125, ShuXinYu228, Weike702, Liyu16, and JinchengNo.6 could be promoted as Cr maize cultivars with low kernel and high stem–leaf accumulation; also, planting these seven varieties can achieve the goal of restoring the heavy metal chromium in farmland soil while ensuring maize food security.
Online and Connected Online Ramsey Numbers of a Matching versus a Path
Authors: Song Ruyu , Zhang Yanbo
Published: November 2022

The (G1,G2)-online Ramsey game is a two-player turn-based game between a builder and a painter. Starting from an empty graph with infinite vertices, the builder adds a new edge in each round, and the painter colors it red or blue. The builder aims to force either a red copy of G1 or a blue copy of G2 in as few rounds as possible, while the painter’s aim is the opposite. The online Ramsey number r˜(G1,G2) is the minimum number of edges that the builder needs to win the (G1,G2)-online Ramsey game, regardless of the painter’s strategy. Furthermore, we initiate the study of connected online Ramsey game, which is identical to the usual one, except that at any time the graph induced by all edges should be connected. In this paper, we show a general bound of the online Ramsey number of a matching versus a path and determine its exact value when the path has an order of three or four. For the connected version, we obtain all connected online Ramsey numbers of a matching versus a path.
Distributed Network of Adaptive and Self-Reconfigurable Active Vision Systems
Authors: Shashank  , Sreedevi Indu
Published: November 2022

The performance of a computer vision system depends on the accuracy of visual information extracted by the sensors and the system’s visual-processing capabilities. To derive optimum information from the sensed data, the system must be capable of identifying objects of interest (OOIs) and activities in the scene. Active vision systems intend to capture OOIs with the highest possible resolution to extract the optimum visual information by calibrating the configuration spaces of the cameras. As the data processing and reconfiguration of cameras are interdependent, it becomes very challenging for advanced active vision systems to perform in real time. Due to limited computational resources, model-based asymmetric active vision systems only work in known conditions and fail miserably in unforeseen conditions. Symmetric/asymmetric systems employing artificial intelligence, while they manage to tackle unforeseen environments, require iterative training and thus are not reliable for real-time applications. Thus, the contemporary symmetric/asymmetric reconfiguration systems proposed to obtain optimum configuration spaces of sensors for accurate activity tracking and scene understanding may not be adequate to tackle unforeseen conditions in real time. To address this problem, this article presents an adaptive self-reconfiguration (ASR) framework for active vision systems operating co-operatively in a distributed blockchain network. The ASR framework enables active vision systems to share their derived learning about an activity or an unforeseen environment, which learning can be utilized by other active vision systems in the network, thus lowering the time needed for learning and adaptation to new conditions. Further, as the learning duration is reduced, the duration of the reconfiguration of the cameras is also reduced, yielding better performance in terms of understanding of a scene. The ASR framework enables resource and data sharing in a distributed network of active vision systems and outperforms state-of-the-art active vision systems in terms of accuracy and latency, making it ideal for real-time applications.

Published: November 2022

In this investigation, two different models for two coupled asymmetrical oscillators, known as, coupled forced damped Duffing oscillators (FDDOs) are reported. The first model of coupled FDDOs consists of a nonlinear forced damped Duffing oscillator (FDDO) with a linear oscillator, while the second model is composed of two nonlinear FDDOs. The Krylov–Bogoliubov–Mitropolsky (KBM) method, is carried out for analyzing the coupled FDDOs for any model. To do that, the coupled FDDOs are reduced to a decoupled system of two individual FDDOs using a suitable linear transformation. After that, the KBM method is implemented to find some approximations for both unforced and forced damped Duffing oscillators (DDOs). Furthermore, the KBM analytical approximations are compared with the fourth-order Runge–Kutta (RK4) numerical approximations to check the accuracy of all obtained approximations. Moreover, the RK4 numerical approximations to both coupling and decoupling systems of FDDOs are compared with each other.

Published: November 2022

Organic fluorescent materials are widely applied in different important fields, such as light-emitting display, explosive detection, molecular imprinting, and so on, because of their low cost, easy functionalization, and large-scale fabrication. In this work, we designed and synthesized a new kind of organic fluorescent polysulfate composite material through post-sulfonation sulfur-fluorine exchange polymerization (a new kind of click chemistry) by symmetric molecular. Sulfur-fluorine exchange polymerization: symmetrical structure SO2F−R1−SO2F molecular reacted with symmetrical OH−R2−OH molecular through nucleophilic reaction in the presence of inorganic base. The polysulfate material was further modified by ClSO3H to get PSE−SO3H materials. Tb3+ was highly dispersed on PSE−SO3H to afford organic-inorganic hybrid fluorescent materials through the conventional coordination chemistry method. The emission wavelength of the organic-inorganic hybrid fluorescent polymer PSE−SO3H−Tb3+ was between 475 and 685 nm, the quantum yield reached 1.18%, and fluorescence lifetime lasted for 730.168 us, with the pure green light emission and long light-emitting lifetime. The fluorescence film was prepared through phase transformation method by the fluorescent polymer material PSE−SO3H−Tb3+. The film has the strong stability property in different pH conditions (pH 1~13). Thus, this kind of organic fluorescent polysulfate composite material may have certain prospects application in terms of detection and luminescence in extreme chemical environments in the future.

New world cutaneous leishmaniasis (NWCL) is an anthropozoonosis caused by different species of the protozoan Leishmania. Colorimetric in situ hybridization (CISH) was shown to satisfactorily detect amastigote forms of Leishmania spp. in animal tissues, yet it was not tested for the diagnosis of human NWCL. The aim of this study was to compare CISH, histopathology (HP), and immunohistochemistry (IHC) techniques to diagnose NWCL in human cutaneous lesions. The sample comprised fifty formalin-fixed, paraffin-embedded skin biopsy specimens from patients with NWCL caused by L. (V.) braziliensis. These specimens were analyzed by CISH, using a generic probe for Leishmania, IHC, and HP to assess the sensitivity of these methods by using a parasitological culture as a standard reference. Additional specimens from three patients diagnosed with cutaneous mycoses were also included to evaluate cross-reactions between CISH and IHC. The sensitivities of IHC, CISH, and HP for detecting amastigotes was 66%, 54%, and 50%, respectively. IHC, unlike CISH, cross-reacted with different species of fungi. Together, these results demonstrate that CISH may be a complementary assay for the detection of amastigote in the laboratorial diagnosis routine of human NWCL caused by L. (V.) braziliensis.

Published: November 2022

Climate change is an inevitable and urgent issue in the current world. African swine fever virus (ASFV) is a re-emerging viral animal disease. This study investigates the quantitative association between climate change and the potential spread of ASFV to a global extent. ASFV in wild boar outbreak locations recorded from 1 January 2019 to 29 July 2022 were sampled and investigated using the ecological distribution tool, the Maxent model, with WorldClim bioclimatic data as the predictor variables. The future impacts of climate change on ASFV distribution based on the model were scoped with Representative Concentration Pathways (RCP 2.6, 4.5, 6.0, and 8.5) scenarios of Coupled Model Intercomparison Project 5 (CMIP5) bioclimatic data for 2050 and 2070. The results show that precipitation of the driest month (Bio14) was the highest contributor, and annual mean temperature (Bio1) was obtained as the highest permutation importance variable on the spread of ASFV. Based on the analyzed scenarios, we found that the future climate is favourable for ASFV disease; only quantitative ratios are different and directly associated with climate change. The current study could be a reference material for wildlife health management, climate change issues, and World Health Organization sustainability goal 13: climate action.

Published: November 2022

Our study addressed mercury contamination hotspots that originated from Chemical Factory Marktredwitz, Germany. The factory was abandoned in 1985 but its legacy has been persistently endangering the river ecosystem of the Ohře River, a Labe (Elbe) River tributary in the Czech Republic. We identified the timing for the peak contamination of fine sediments entering the Skalka Reservoir located on the Ohře River downstream of the Czech German boundary. Age constraints for the reservoir sediments were obtained using gamma spectrometry analyses of 137Cs and unsupported (excess) 210Pb. We also summarised historical and current Hg concentrations in suspended particulate matter in the Kössein–Röslau–Ohře river system and recent Hg concentrations in aquatic plants. Secondary contamination and its transfer to the Czech stretch of the Ohře River and the Skalka Reservoir through severely contaminated suspended material peaked during the period of factory closure and the start of remediation. The Hg contamination import to the Czech Republic is not likely to improve if the river is left without traditional management of bank reinforcement. This case study highlights a gap in safety regulations for the management of severely contaminated rivers and demonstrates the need to consider the role of historical contamination in river ‘renaturation’.
Dietary Changes in the Ark Clam (Anadara kagoshimensis) Is Associated with Phytoplankton Community Patterns in a Temperate Coastal Embayment

Published: November 2022

The monthly phytoplankton communities and dietary items of the filter-feeding ark clam (Anadara kagoshimensis) in cultivation were examined in a shallow temperate coastal embayment of Yeoja Bay in Korea, to identify dietary changes in clams associated with phytoplankton community patterns. A self-organizing map (SOM) algorithm was applied to shape the community structures of phytoplankton. Clam δ13C and δ15N values were determined monthly and compared with those of phytoplankton, microphytobenthos, suspended particulate organic matter (SPOM), sedimentary organic matter (sedimentary OM), and Phragmites australis. Our SOM clustered monthly phytoplankton communities, revealing a seasonal shift in the dominance of large-sized diatoms (sporadically together with dinoflagellates), which were detected almost year-round, to small-sized taxa (chlorophytes, prasinophytes, and prymnesiophytes), which were observed in May–June. The δ13C and δ15N measurements revealed that pelagic and benthic diatoms serve as the main contributors to the clam diets. A reduction in their dietary contribution accompanied a considerable increment in the contribution of Phragmites detritus in association with the dominance of small-sized phytoplankton during the late spring. Our results suggest that the dominance of small-sized phytoplankton during the critical spring period of the clam life cycle may decrease the availability of preferred items (i.e., size-related food quality) and lead to dietary changes in the clams in relation to climate forcing in this warming sea.

This paper aims to present aspects related to corporate governance, organisational resilience and sustainable practices developed by Brazilian companies during the COVID-19 pandemic. The methodological strategy included documentary research to identify sustainability reports published by companies listed on the Ibovespa index, which were examined through the content analysis technique. The results allowed light to be shed on opportunities for improvement concerning sustainability and corporate governance. Regarding organisational resilience, risk management is central for the development of sustainability practices by organisations. The support to society related to the COVID-19 pandemic was evidenced mainly through the donation of financial resources, equipment and hospital supplies. Practices related to reducing energy consumption and minimising waste generation were those most associated with environmental aspects. The actions identified were mapped according to their relations with the SDGs. Managers can benefit from the information presented in this study to enhance organisational sustainability and resilience, while researchers can use it as a starting point for future studies.

Published: November 2022

Amid global disturbances, the calls for educational institutions to promote peace and counter hostility intensify. However, policymakers and other adults typically draft the various programs developed for schools to pursue this mission. While young people have valuable insights into the realities and issues around them, their ideas are rarely solicited in this respect. This study contributes towards filling this gap by bringing insights from Finnish youth on how to address hostile attitudes and foster the development of more peaceful futures in and through education. The data were gathered through an online survey sent to students in upper-secondary education (16- to 20-year-olds) in Finland. The survey included an open-ended question on how schools could address hostile attitudes. In total, 2744 students answered this question, and their responses composed the data of this study. Through qualitative analysis, we found that their suggestions concerned both the academic and social dimensions of school education in addressing hostile attitudes. The students highlighted that to change people’s attitudes and beliefs, they need to know more, and most importantly, they need to know differently. They proposed self-reflection and dialogue as pedagogical tools for the critical examination of one’s taken-for-granted assumptions. The students’ ideas align well with the tenets of transformative learning, which could be valuable in developing educational approaches for more peaceful societies.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza viruses produce a wide range of clinical disease severity, which varies from asymptomatic infection to death. The outbreak of coronavirus disease 2019 (COVID-19) in Wuhan, Hubei, China, followed a seasonal influenza pandemic. The prevalence of influenza has changed since the outbreak of COVID-19. In this study, we have compared the prevalence of influenza and COVID-19 since the onset of the pandemic. Clinical symptoms were also assessed among patients. Materials and Methods: The present study was conducted in a single center on 229456 patients with the SARS in Hormozgan province, Iran, during 2019-2021 before and after the COVID-19 pandemic. Clinical features including age, sex, fever, cough, shortness of breath, nausea, dizziness, headache, body aches, and diarrhea were also analyzed. Results: The results indicated that out of a total of 229456 samples of patients, 71142 (31.00%) and 527 (.22%) cases were diagnosed with positive COVID-19 and positive influenza, respectively. Influenza activity decreased in March 2020 and remained low until September 2021, but it increased to near pre-pandemic seasonal levels since October 2021. The outbreak of influenza decreased by starting the restrictions and health protocols. Furthermore, the analysis of patients’ symptoms indicated that the most prevalent symptoms in influenza patients were fever, cough, and body pain, while the symptoms in COVID-19 patients were cough and headache. Conclusion: Social restrictions and adherence to health protocols could significantly reduce the incidence of seasonal influenza even after controlling the COVID-19 pandemic. Influenza and COVID-19 have similar symptoms in patients, so diagnostic tests are necessary for proper diagnosis and management.

Published: November 2022

Background: The polymorphism associated with liver fat content, which is well-known as PNPLA3 rs738409 (Patatin-like phospholipase domain-containing protein 3), is one of the critical subjects widely investigated in the literature regarding the prevalence of non-alcoholic fatty liver disease (NAFLD) worldwide. The present research aimed to study the bioinformatics investigations of this polymorphism together with the in vitro analyses among patients with NAFLD. Materials and Methods: In this case-control study, after performing bioinformatics analysis, the laboratory examination was performed in several steps. Genomic DNA was extracted from the blood of 53 NAFLD patients and 107 subjects with normal liver ultrasounds. PNPLA3 rs738409 was genotyped by the polymerase chain reaction-restriction fragment length polymorphism method. The laboratory test results, including fasting blood sugar, triglyceride, cholesterol, high-density lipoprotein, low-density lipoprotein, alanine aminotransferase, and aspartate aminotransferase were collected from medical records. Finally, statistical analysis was performed using SPSS software, version 18.0. Results: The frequency of the G allele was 56% and 36% among patients and in the control group, respectively. The frequency of genotypes was 35.8% and 47.7% (CC), 17% and 31.8% (CG), 47.2% and 20.6% (GG) in patients and control groups, respectively. The adjusted odds ratios for PNPLA3 rs738409 C>G were 3.0 (95% confidence interval [CI]: 1.28-6.98, P=.011) and 0.68 (95% CI: 0.25- 1.83, P = .44) for GG and CG genotypes, respectively. Conclusion: The findings showed the association between the GG genotype and the presence of NAFLD. Furthermore, the bioinformatics findings suggested the probable risk of the disease incidence regarding the change of hydropathic characteristics resulting from the amino acid substitution.

Background: Multiple sclerosis (MS) is a common disease of the central nervous system. The main cause of this disease is related to the myelin damage of nerve cells. This study aimed to compare the effectiveness of acceptance and commitment therapy (ACT) and mindfulness-based cognitive therapy (MBCT) on illness perception and adherence to the treatment of patients with MS. Methods: This is a quasi-experimental study with a pre-test, post-test, and follow-up design with a control group. The statistical population of this study included all patients with MS under the auspices of the MS Society of Tehran (Iran) in 2019. Forty-five women with MS were purposefully selected and randomly divided into MBCT, ACT, and control (n=15) groups. Data were obtained using the revised illness perception questionnaire (IPQ-R) and the MS treatment adherence questionnaire (MS-TAQ). The repeated measurement analysis of variance and SPSS.22 were used to analyze data. Results: The results showed that the effect of MBCT was greater than that of the acceptance and commitment-based therapy group on illness perceptions (P<0.001) and treatment adherence (P<0.001). Conclusion: Overall, the effectiveness of MBCT was greater than that of the ACT group on illness perceptions and adherence to treatment. MBCT and ACT can be employed as effective methods for patients with MS.

Background: To date, limited studies have evaluated the role of vitamin A in acute pyelonephritis (APN). Accordingly, we aimed to investigate the effect of this vitamin on the prevention of renal damage in children with APN. Methods: This assessor-blind randomized controlled trial included 108 children with APN, aged 3 months to 14 years, who were admitted to Bandar Abbas Children’s Hospital, Bandar Abbas, Iran, in 2020. Patients were randomly allocated to two equal groups. Children in the vitamin A group received vitamin A in addition to antibiotics (ceftriaxone), while those in the control group only received antibiotics. Then, children in both groups underwent dimercaptosuccinic acid (DMSA) scanning once at baseline and four months after treatment. Photopenic areas in the DMSA scan were regarded as damaged areas. Further, serum vitamin A levels, C-reactive protein (CRP) levels, and erythrocyte sedimentation rate (ESR) were measured in all participants before the initiation of treatment. Finally, the demographic features of the participants were noted, including age and gender. Results: Patients in both groups were comparable regarding age and sex. Serum vitamin A levels, CRP, and ESR did not differ significantly between groups before treatment. The mean number of photopenic areas in the baseline DMSA scan was similar in both groups (P=0.481); however, the mean number of photopenic areas in the DMSA scan after four months was significantly lower in the vitamin A group compared to controls (P=0.004). Conclusion: Therefore, the use of vitamin A, along with antibiotics can significantly decrease renal damage in children with APN.

Introduction: Antimicrobial resistance identification for each hospital has benefits in management of nosocomial infections. Objectives: The aim of this study was to determine antimicrobial susceptibility of meropenem against Acinetobacter and Klebsiella strains in samples obtained from hospitalized patients with ventilator-associated pneumonia (VAP). Patients and Methods: In this cross-sectional study, 100 patients with VAP were selected from the intensive care unit (ICU) of Amin hospital in Isfahan. Lung secretions were collected and tested for bacterial infections. In samples with the positive bacterial infection, E-test and agar diffusion test were used to determine and compare the susceptibility of Acinetobacter and Klebsiella strains to meropenem. Results: The two susceptibility testing methods – E-test and agar diffusion test – showed similar results in 87 cases (87%) therefore, 84 cases were resistant and three cases were susceptible to meropenem. However, in 13 cases, the result of the agar diffusion test was resistant and the result of E-test was sensitive. According to the Kappa test, the agreement between the two tests was 0.87 and statistically significant (P <0.001). Conclusion: Due to the high resistance of Klebsiella and Acinetobacter strains to meropenem, it should not be used as an experimental treatment in patients diagnosed with VAP caused by these strains. We recommend using meropenem for Acinetobacter and Klebsiella after susceptibility testing by E-test confirmed its efficacy.

Introduction: Sickle cell disease (SCD) is one of the hereditary blood disorders that affects the red blood cells. Several lines of evidence indicated that the vitamin D deficiency (VDD) is quite common in children with SCD and vitamin D supplementation enhanced health-related quality of life in these patients. The present study is aimed to assess the exact prevalence of VDD in SCD patients using meta-analysis. Materials and Methods: A systematic search was conducted in PubMed and Google Scholar to extract the papers that contain prevalence data and numbers of patients with VDD in SCD patients and healthy people. Pooled prevalence was estimated using MAJOR module of Jamovi library. The overall risk ratio of having VDD in patients with SCD was calculated using the Review Manager (RevMan 5.4.1) program. Results: A total of 26 prevalence estimates from 25 papers were included in the meta-analysis. The pooled prevalence of VDD among SCD patients is 60% (95% CIs: 50%-70%). Further, VDD is not significantly different in both SCD patients and healthy controls (risk ratio of 1.28 and 95% CI of 0.81-2.04). Conclusion: Results of this meta-analysis indicate prevalence of VDD in SCD patients. Further, a well-designed, placebo-controlled RCTs have to be conducted to determine the effects and the safety of vitamin D supplementation in children and adults with SCD.

Introduction: Thyroid status because of the expression of angiotensin-converting enzyme-2 (ACE2), which is a functional receptor for coronavirus disease 2019 (COVID-19) in thyroid glands, maybe affects COVID-19 patients’ outcomes. Objectives: This study aimed to evaluate the correlation of thyroid status with the severity and mortality of COVID-19 patients. Patients and Methods: In a retrospective cohort study conducted on 521 COVID-19 patients, data were collected by a demographic questionnaire and a checklist of patient outcomes (death/recovery) from the hospital information system (HIS) and analyzed by SPSS version 26 and binary logistic regression. Data about thyroid status were collected from clinical documents and laboratory test data. Results: Most patients were male (57.2%) with a mean age of 56.12 ± 17.4 years. Seventy-seven patients had a severe stage of disease, and 55 patients died. Twenty-one patients had hyperthyroidism, and 53 patients had hypothyroidism. Results showed that the correlation between hypothyroidism and hyperthyroidism with severity and mortality risk of COVID-19 patients was insignificant (P > 0.05). Conclusion: In this study, we concluded that, thyroid status is not associated with COVID-19 outcomes such as severity or mortality.
Interference caused by anti-streptavidin antibodies in a parathyroid hormone assay; a case report
Authors: Trautz Benjamin Siegfried , Negele Thomas
Published: November 2022

Endogenous antibodies can lead to test interference in streptavidin-biotin based laboratory assays, such as thyroid function tests or parathyroid hormone (PTH) levels. We report about a patient, who presented for thyroid surgery, showing undetectable PTH levels despite normocalcaemia in internally assessed preoperative laboratory work. Previously, anti-streptavidin antibodies were detected in the patient’s blood and normal PTH levels could be measured in a streptavidin-free assay. To our knowledge this is the first reported case of a clinically relevant PTH test interference due to endogenous anti-streptavidin antibodies, thus complicating the evaluation of postoperative hypoparathyroidism.

Introduction: Apoptosis is a programmed cell death commonly investigated in researches. Objectives: According to the lack of a gold standard for definition of apoptosis, we conducted a pilot analysis to propose a new definition for apoptosis based on a previous gene expression data. Materials and Methods: As a secondary analysis, a gene expression data of a vitrification thawing induced model of apoptosis conducted on ten mice ovaries was used. Half of the samples had been treated with selenium. P53, Fas, Bax and Bcl2 were considered as apoptosis related genes. Their +∆CTs were reported. An apoptosis scoring system was designed based on regression analysis. Results: In multiple regression of the genes, the only significant association was for Bcl2 expression for prediction of apoptosis. Then a model was designed consisting of Bcl2 and some interactions that the calculated amount of its formula was considered as the scoring system (R2 = 0.989, P (>F) <0.001, Root mean square deviation = 0.082). Bax/Bcl2 ratio showed an acceptable goodness of fit for prediction of this score (R2 = 0.845, P (>F) <0.001, root mean square deviation = 0.219). No conclusive result was found for factor analysis. Conclusion: The present study used a simple approach to propose statistical models for apoptosis. A comprehensive criterion should be designed apoptosis and other biological systems to be considered as a gold standard.
