Cholesterol granuloma of the maxillary sinus in association with a dental implant—A case report
Authors: Vikram Vignesh , Raja Sunitha , Ramanathan Manikandhan 
Published: October 2022

AbstractBackgroundCholesterol granuloma is typically a benign granulomatous growth seen mostly in the mastoid process and the petrous temporal bone. Although cholesterol granuloma in maxillary sinus was first reported in the scientific literature in 1978, the occurrence is very rare and it is usually clinically and radiographically manifested ambiguously as maxillary sinusitis.PurposeThe presence of cholesterol granuloma in the maxillary sinus in association with a dental pathology or prosthesis has been scarcely known. In this case report, we present a case of cholesterol granuloma in the maxillary sinus of a middle‐aged male who had previously undergone dental implant placement in relation to that anatomical location.Materials and MethodsA 64‐year‐old man reported to the Dental OP with a chief complaint of oral malodor, swelling, and tenderness over the right middle third of the face for the past 3 months. A cone beam computed tomography scan showed a well‐defined radio‐opaque lesion along with sclerosis and thinning of bone within the right maxillary antrum in relation to the dental implant placed in the 16 regions. The left maxillary sinus appeared normal. The Caldwell‐Luc procedure was performed and a solitary soft lesion with yellowish‐gray contents was evident within the right maxillary sinus. Histopathological examination revealed cholesterol clefts surrounded by foreign body giant cell reaction and granulation tissue formation, along with the presence of old and recent hemorrhage. A final diagnosis of cholesterol granuloma was made based on the histopathological examination report.ConclusionBased on the evidence available in the present case, we hypothesize that the localized trauma and hemorrhage initiated by implant placement in this particular anatomical location could have plausibly resulted in the occurrence of cholesterol granuloma in our patient.

AbstractBackgroundThe burden of occupational hand eczema in hairdressers is high, and (partly strong) allergens abound in the hair cosmetic products they use.ObjectivesTo systematically review published evidence concerning contact allergy to an indicative list of active ingredients of hair cosmetics, namely, p‐phenylenediamine (PPD), toluene‐2,5‐diamine (PTD), persulfates, mostly ammonium persulfate (APS), glyceryl thioglycolate (GMTG), and ammonium thioglycolate (ATG), concerning the prevalence of sensitization, particularly in terms of a comparison (relative risk; RR) between hairdressers and non‐hairdressers.MethodsFollowing a PROSPERO‐registered and published protocol, eligible literature published from 2000 to February 2021 was identified, yielding 322 publications, and extracted in standardized publication record forms, also considering risk of bias.ResultsBased on 141 publications, the contact allergy prevalence to PPD was 4.3% (95% CI: 3.8–4.9%) in consecutively patch tested patients. Other ingredients were mostly tested in an aimed fashion, yielding variable, and partly high contact allergy prevalences. Where possible, the RR was calculated, yielding an average increased sensitization risk in hairdressers of between 5.4 (PPD) and 3.4 (ATG). Additional evidence related to immediate‐type hypersensitivity, experimental results, exposures, and information from case reports was qualitatively synthesized.ConclusionsAn excess risk of contact allergy is clearly evident from the pooled published evidence from the last 20 years. This should prompt an improvement in working conditions and product safety.

AbstractIntroductionThe aim of this review was to combine the results of published cohort studies to determine the exact association between chronic liver disorders, and the severe form of COVID‐19, and its associated complications.MethodsThis meta‐analysis employed a keyword search (COVID‐19 and chronic liver disorders) using PubMed (Medline), Scopus, Web of Sciences, and Embase (Elsevier). All articles related from January 2019 to May 2022 were reviewed. The STATA software was used for analysis.ResultsThe risk of death in COVID‐19 patients with chronic liver disorders was higher than in ones without the chronic liver disease (RR: 1.52; CI 95%: 1.46–1.57; I2: 86.14%). Also, the risk of acute respiratory distress syndrome (ARDS) and hospitalization in COVID‐19 patients with chronic liver disorders was higher than in ones without the chronic liver disease ([RR: 1.65; CI 95%: 1.09–2.50; I2: 0.00%] and [RR: 1.39; CI 95%: 1.23–1.58; I2: 0.20%]). Also, the meta‐analysis showed cough, headache, myalgia, nausea, diarrhea, and fatigue were 1.37 (CI 95%: 1.20–1.55), 1.23 (CI 95%: 1.09–1.38), 1.25 (CI 95%: 1.04–1.50), 1.19 (CI 95%: 1.02–1.40), 1.89 (CI 95%: 1.30–2.75), 1.49 (CI 95%: 1.07–2.09), and 1.14 (CI 95%: 0.98–1.33), respectively, whereas the risk of all these symptoms was higher in COVID‐19 patients with chronic liver diseases than ones without chronic liver disorders.ConclusionThe mortality and complications due to COVID‐19 were significantly different between patients with the chronic liver disease and the general population.

AbstractBackgroundThe causal inference between leisure sedentary behaviour (LSB) and rheumatoid arthritis (RA) is still controversial because of potential residual confounding and reverse causality.MethodsThe present study used publicly available large‐scale genome‐wide association studies (GWAS) of LSB (television watching, computer use, and driving) and RA to perform a two‐sample Mendelian randomization (MR) study to evaluate the causal effect of LSB on the risk of RA. We detected significant causal associations using the multiplicative random effects‐inverse variance weighted (MRE‐IVW) method, the maximum likelihood, robust adjusted profile scores, the weighted median, MR‐Egger regression, and several complementary sensitivity analyses. Risk factor analysis was also conducted to further investigate potential mediators linking causal inference.ResultsIncreased genetic liability to leisure television watching was significantly associated with a higher risk of RA (MRE‐IVW method; OR = 2.46, 95% CI 1.77–3.41; p = 8.35 × 10−8). MR estimates indicated that prolonged leisure computer use was causally associated with a lower risk of RA (MRE‐IVW method; OR = 0.23, 95% CI 0.12–0.46; p = 2.19 × 10−5). However, we found no evidence for a causal effect of leisure driving on the risk of RA (MRE‐IVW method; OR = 0.59, 95% CI 0.10–3.41; p = 0.557). No pleiotropy was detected by the sensitivity analysis.ConclusionsThis study supports a causal association between prolonged leisure television watching and an increased risk of RA. Additionally, prolonged computer use might be a protective factor for RA.
‘Los von London’: A comparative, empirical analysis of German and British global foreign banking and trade development, 1881–1913
Authors: Kisling Wilfried 
Published: October 2022

AbstractThe role of finance in the development of trade draws increasing attention from economists and economic historians. Yet empirical studies, especially from an historical perspective, continue to be scarce. This study analyses the role of German and British foreign banks in the internationalisation of trade during the first globalisation. It creates a novel data set on the bilateral trade of Germany and Great Britain with the rest of the world and the number and geographical distribution of German and British foreign banks between 1881 and 1913. Using an augmented gravity model of trade, the article shows that banks had a significant positive impact on exports and imports and that this effect was even more pronounced in case of German banks and trade. Moreover, the effect of German banks on trade is the highest in the years closer to bank entry, supporting the idea of German banks being initiators of trade. In contrast, the effect of British banks seems constant over time.

AbstractWith the impact of the COVID‐19 epidemic, the demand for masked face recognition technology has increased. In the process of masked face recognition, some problems such as less feature information and poor robustness to the environment are obvious. The current masked face recognition model is not quantified enough for feature extraction, there are large errors for faces with high similarity, and the categories cannot be clustered during the detection process, resulting in poor classification of masks, which cannot be well adapted to changes in multiple environments. To solve current problems, this paper designs a new masked face recognition model, taking improved Single Shot Multibox Detector (SSD) model as a face detector, and replaces the input layer VGG16 of SSD with Deep Residual Network (ResNet) to increase the receptive field. In order to better adapt to the network, we adjust the convolution kernel size of ResNet. In addition, we fine‐tune the Xception network by designing a new fully connected layer, and reduce the training cycle. The weights of the three input samples including anchor, positive and negative are shared and clustered together with triplet network to improve recognition accuracy. Meanwhile, this paper adjusts alpha parameter in triplet loss. A higher value of alpha can improve the accuracy of model recognition. We further adopt a small trick to classify and predict face feature vectors using multi‐layer perceptron (MLP), and a total of 60 neural nodes are set in the three neural layers of MLP to get higher classification accuracy. Moreover, three datasets of MFDD, RMFRD and SMFRD are fused to obtain high‐quality images in different scenes, and we also add data augmentation and face alignment methods for processing, effectively reducing the interference of the external environment in the process of model recognition. According to the experimental results, the accuracy of masked face recognition reaches 98.3%, it achieves better results compared with other mainstream models. In addition, the hyper‐parameters tuning experiment is carried out to improve the utilization of computing resources, which shows better results than the indicators of different networks.

AbstractObjectiveThe main aim of this research is to determine whether positive or negative maternal reactions in the field of emotional socialization play an intermediary role in the relationship between a child's emotional regulation skills and aggressive behavior.BackgroundPrevious findings show the effects of children's emotion regulation skills and parents' emotional socialization responses on aggressive behavior. However, researchers have not reported how children's emotion regulation skills influence maternal emotional socialization responses or investigated the mediating role of maternal emotional socialization responses on emotion regulation and aggressive behavior.MethodThe study was conducted with 285 mothers of 60‐ to 72‐month‐old children attending preschool. Research data were collected using the Children Aggression Scale—Parent Version, Dealing With Negative Emotions of Children, Emotional Regulation Checklist, Attachment Insecurity Screening Inventory, Parental Attitude Scale, and Child–Parent Relationship Scale.ResultsPositive and negative responses of mothers play a mediating role in the relationship between children's aggression and emotional regulation. Mothers' positive responses were effective in reducing the aggression level of children with a low level of emotional regulation. In addition, even if children's emotional regulation skills are low, positive responses are effective in reducing mothers' negative reactions and thus children's aggression levels.ImplicationsGiven the importance of promoting positive development in children, this study may have important implications for intervention and prevention programs. In particular, family‐based interventions that encourage mothers to use emotional socialization applications and education/techniques that encourage parents' emotional regulation strategies are recommended.

Microsatellite instability (MSI) is a major carcinogenic pathway with prognostic and predictive implications. The validity of polymerase chain reaction (PCR)‐based MSI testing is well established in colorectal cancer; however, the data are limited in non‐colorectal gastrointestinal cancers. The aim of this study is to clarify the detailed MSI profiles of non‐colorectal gastrointestinal cancers and to investigate the differences from those of colorectal cancers. MSI testing was performed using paired tumour/normal tissues of 123 mismatch repair‐deficient cancers detected by immunohistochemistry including 80 non‐colorectal cancers (eight oesophagogastric junction (EGJ), 57 gastric and 15 small intestine) and 43 colorectal cancers. Fragment size analysis revealed that the mean nucleotide shifts of five markers (Promega panel) were the highest in the stomach (6.4), followed by colorectum (5.7), small intestine (5.0) and EGJ cancers (mean = 4.0; P = 0.015, versus stomach). All cases showed ≥ 1 nucleotide shift in ≥ 2 markers and were considered as MSI‐high. However, when the cut‐off was set to ≥ 3 nucleotide shifts in ≥ 2 markers, three EGJ (37.5%), two small intestine (13.3%) and two gastric (3.5%) cancers showed false‐negative results. In addition, cases with isolated loss of MSH6 or PMS2 showed smaller nucleotide shifts than those in others. MSI testing is applicable to non‐colorectal gastrointestinal cancers; however, a subset can yield false‐negative results due to subtle nucleotide shift in multiple markers. Analysis of paired tumour/normal tissues and careful interpretation is necessary to avoid false‐negative results and ensure appropriate treatment.
Effect of Y2O3additive on nitridation of diamond wire silicon cutting waste

Published: October 2022

AbstractThe effect of Y2O3additive on the nitridation of diamond wire silicon cutting waste (DWSCW) was studied by using X‐ray diffraction, thermo gravimetry, differential thermal analysis, scanning electron microscope equipped with energy‐dispersive spectrometry, and an equivalent alternative method, and the individual particles of DWSCW were simulated using cubic polycrystalline silicon blocks. The results showed that the native SiO2film on the surface of DWSCW can be disrupted at low temperature (1300°C) by adding Y2O3additive, which provide good channels for the diffusion of SiO and N2and improve the overall conversion of DWSCW. Y2O3additive can also reduce the initial nitriding temperature of cutting waste, change the nitriding kinetic behavior, and promote the formation of β‐Si3N4through accelerating the nitridation of cutting waste at high temperature (≥1500°C). In addition, when 8 wt% Y2O3additive is added to the cutting waste, the complete nitridation is achieved, at 1350°C, andωα + ωβreaches a maximum of 83.6 wt%.

AbstractThe mud star Ctenodiscus crispatus has a broad distribution from Arctic waters into the northern Atlantic and Pacific oceans. Populations in the Atlantic are well studied and show oocyte sizes indicative of continuous gametogenesis with aseasonal spawning. In contrast, knowledge on the reproductive biology of Pacific populations is lacking. Thus, this study aims to examine the reproduction of C. crispatus in the northeastern Pacific. We sampled a population from the Pacific Ocean off Oregon and confirmed the species identity through 16S and cytochrome oxidase subunit I (COI) genetic barcoding. The majority of adults were 22–27 mm in size. Oocytes were obtained from dissected gonads soaked in a 1‐methyladenine solution and fertilized with spawned sperm. Other individuals were preserved whole in 10% buffered formalin, and oocytes were measured from preserved gonads. Strip‐spawned oocytes had a mean diameter of ~485 μm, consistent with Atlantic populations. Sperm had a mean head diameter and flagellum length of 3.1 and 65.9 μm, respectively. The time between first and second cell divisions was ~2 h, but larval cultures failed, and very few embryos developed to blastulae. Both strip‐spawned and preserved oocytes had a bimodal size‐frequency distribution indicative of semicontinuous gametogenesis. Comparison among individuals showed evidence of asynchrony among the population. This asynchrony and bimodal oocyte distribution may be driven by regular pulses of food, as has been postulated for other populations of this species. The reproductive plasticity seen among populations of this species in different regions could explain how it successfully inhabits such a wide geographic range.

Published: October 2022

AbstractPredicting the properties of glass based on compositional and structural information is a fundamental issue with enormous practical and industrial significance for the study of laser glass. Here we address this problem and demonstrate the application of phase diagram method in predicting the spectroscopic properties of Nd3+‐doped binary and ternary silicate, binary phosphate, and borate laser glasses from their initial congruently melting compounds. In particular, spectroscopic properties, such as effective linewidth (Δλeff) and fluorescence branching ratio (β) can be precisely predicted in all glass systems with an error less than 5%. Furthermore, a composition–structure–property database of Nd3+‐doped ternary silicate glass system is established and preliminarily applied to the composition design and explanation of commercial glass. This study provides interpretable predictions of the optical and spectroscopic properties for Nd3+‐doped laser glasses.

AbstractAimsTo investigate women's childbirth experiences and their relation to self‐esteem development in the postpartum year.DesignA mixed methods study.MethodsWomen (N = 125) completed survey questionnaires regarding their self‐esteem and childbirth experiences at three time points in 2020–2021: third trimester of pregnancy (T1), 4–8 weeks postpartum (T2) and 1 year postpartum (T3). The survey results were analysed using qualitative thematic and quantitative path analyses with latent change factors. The open‐ended answers of the women who demonstrated a change in self‐esteem between T2 and T3 were then compared. The STROBE checklist was used as the reporting guideline.ResultsThe quantitatively measured childbirth experiences predicted statistically significantly and positively the changes in self‐esteem in the following year. The women described their childbirth stories through three main themes: childbirth as a lived experience, childbirth as a relational event and childbirth as a medical event. On the basis of the thematic analysis, we propose that the relationship between childbirth experience and self‐esteem development might only hold for women with extremely positive or negative childbirth experiences. There were mixed results for those women who had mixed experiences, indicating that other factors probably contributed to the changes in self‐esteem.ConclusionChildbirth is a pivotal event that may have lasting effects on the mother's self‐esteem after childbirth. Especially women with traumatic experiences deserve attention because they are at risk of the most negative consequences.ImpactPerinatal services and policy makers must recognize the importance of childbirth experiences in women's well‐being and improve their practices. Different cultural models of childbirth should be recognized and supported to facilitate good experiences and prevent traumatic ones.Patient or Public ContributionService users recruited in Finnish Child Health Centers responded to surveys that were used as data for this study.

AbstractWe evaluated the relationships between Berlin questionnaire (BQ) scores, hypertension and other metabolic variables in 598 subjects (age: 65.8 ± 10 years, mean ± SD) enrolled in the PAMELA (Pressioni Arteriose Monitorate E Loro Associazioni) study representative of the general population, treated or untreated with antihypertensive drugs. Two hundred and eleven subjects (35%) had a positive BQ with two or more positive categories of the inquiry. Compared to those without sleep disorders these subjects showed a greater male prevalence (55.9%), worse serum cholesterol, triglycerides and glucose profile, greater body mass index (BMI) (28.9 ± 4.9 vs. 24.9 ± 3.4 kg/m2), higher office (and to a lesser extent 24‐h) BP and HR values, higher serum creatinine values and greater rate of echocardiographic left ventricular (LV) hypertrophy (25% vs. 13%). These differences were not detected when the data analysis was restricted to treated hypertensive patients. Thus, BQ scores allow to identify among subjects belonging to a general population those with elevated BP, organ damage and altered metabolic. When antihypertensive drug treatment is present, however, the approach fails to detect differences between groups with low or high BQ index.
