Retracted: Rare Earth Nd3+ Doping Cobalt-Cadmium Nanoferrites Structural, Optical, and Magnetic Properties and Applications
Authors: Kumar N. Hari
Published: June 2024

Nanoscale particles of neodymium-substituted cobalt-cadmium generic formula for nanoferrite Co0.4Cd0.6NdxFe2−xO4 samples at X = 0.000, 0.003, 0.005, 0.007, 0.009, and 0.011 were studied. The prepared powders were synthesised at low temperatures using citrate gel auto-combustion process. The synthesised powders were calcined at 500 °C for four hours. The morphological properties of the sintered powders were investigated, and their crystal structure was determined by X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD peaks confirmed the spinel ferrite structure. The lattice parameter was calculated from the XRD and showed decreasing trends with 8.442 to 8.308. SEM revealed an irregularly-shaped grain morphology with a homogeneous distribution. Raman spectroscopy analysis showed slight frequency changes in the Raman modes in doped samples, attributed to variations in the cation distribution. The peaks are located at 191, 291, 461, 591, and 671 cm−1. UV spectroscopy studies showed that the energy band gap values decrease with increasing Nd3+ concentration. Direct optical band gap values obtained were 1.238, 1.248, 1.199, 1.135, 1.134, and 1.101 eV with increasing Nd doping. The magnetic hysteresis properties were determined using a SQUID-VSM magnetometer. The hysteresis curves of Co0.4Cd0.6NdxFe2−xO4 nanoparticles show an increase in coercivity with increasing doping concentration. This enhancement is attributed to the multi-domain behaviour.

Published: June 2024

Objective. To assess repeatability and agreement of central vault for implantable collamer lens (ICL) measured by the Tomey OA‐2000 biometry and Spectralis optical coherence tomography (OCT). Methods. In this prospective study, the central vault was measured by the Tomey OA‐2000 biometer and Spectralis OCT in 84 eyes (43 patients) after ICL implantation at six month follow‐up. Three consecutive scans were obtained by one experienced technician using Tomey OA‐2000 and the Spectralis OCT in the same day. The coefficient of variation (CoV), intraclass correlation coefficient (ICC), within‐subject standard deviation (Sw), and 2.77 Sw were calculated to assess the repeatability and reproducibility. The paired t‐test and Bland–Altman plots were used to analyze the differences and agreements of central vault measured by two devices. Results. Repeatability of the central vault measured by Tomey OA‐2000 biometer and Spectralis OCT showed that the CoV was 2.71% and 1.66%, respectively. The ICC for both devices was 0.996 and 0.999, respectively. The paired t‐test showed that central vault measured by Tomey OA‐2000 biometer was −7.25 ± 23.57 microns lower than that measured by Spectralis OCT (P = 0.006). The mean difference between measurements for Tomey OA‐2000 and ASM‐OCT with 95% limits of agreement (LoAs) was −38.94 to 53.44 μm. Conclusion. Both Tomey OA‐2000 biometer and Spectralis OCT displayed good repeatability for the measurement of central vault of ICL. Good reliability and agreement were observed between Tomey OA‐2000 biometer and Spectralis OCT. Both instruments are useful but not replaced each other for central vault measurements.
Effects of Renal Denervation on Ouabain‐Induced Hypertension in Rats
Authors: Tang Minna , Hu Jialu , Li Wenshu , Zhang Ningzhi , Ning Sisi , Yan Yan , Cui Zhaoqiang
Published: June 2024

Background. Ouabain, a Na+, K+‐ATPase inhibitor, is elevated in hypertensive patients. Evidence suggests ouabain contributes to hypertension mainly through activation of the sympathetic nervous system (SNS). Renal nerves play a vital role in the regulation of SNS activity, so we hypothesize that renal denervation may attenuate the development of ouabain‐induced hypertension. Methods and Results. Forty Sprague‐Dawley rats were divided into following groups (n = 10 each): control group (sham surgery plus intraperitoneal saline injection), RDN group (renal denervation (RDN) plus intraperitoneal saline injection), ouabain group (sham surgery plus intraperitoneal ouabain injection), and ouabain + RDN group (RDN plus intraperitoneal ouabain injection). After eight weeks, compared with the control group, rats in the ouabain group exhibited elevated blood pressure (P < 0.05), increased plasma epinephrine, norepinephrine, angiotensin II, and aldosterone levels (P < 0.05). These indexes could be significantly ameliorated by RDN. RDN also reduced the thickening of aortic tunica media and downregulated the expression of proliferating cell nuclear antigen (PCNA) in the thoracic aorta induced by ouabain. Masson staining and echocardiography showed that myocardial fibrosis and increased left ventricular mass in the ouabain group could be attenuated by RDN. Conclusions. The present study reveals that renal nerves play an important role in the development of ouabain‐induced hypertension. RDN could inhibit the pressor effect and the myocardial remodeling induced by ouabain potentially via inhibiting catecholamine release and vascular smooth muscle cell proliferation. Clinical studies are needed to explore whether RDN may exhibit better antihypertensive effects on hypertensive patients with high plasma ouabain levels as compared to those with normal plasma ouabain levels.
Left Pulmonary Artery Stenting for Left Pulmonary Artery Stenosis Following Patent Ductus Arteriosus Device Closure: Case Series and Review of the Literature
Authors: Molina Víctor , Hadid Mehdi , Miró Joaquim , Dahdah Nagib
Published: June 2024

Percutaneous device occlusion is currently the standard of care for most cases of patent ductus arteriosus (PDA). Albeit infrequent, device‐related left pulmonary artery (LPA) stenosis is a known complication of this procedure, occasionally requiring stent placement to relieve the obstruction. We present a series of four patients who required left pulmonary stenting after ductus arteriosus device closure. A review of the current evidence is presented.
Parathyroid Paranoia: Unveiling Psychosis in Hyperparathyroidism
Authors: Murphy Rachael J. , Paul Subin , Primelo Ralph
Published: June 2024

Primary hyperparathyroidism (PHPT) and subsequent hypercalcemia have been reported to be associated with psychosis. Here we report the case of a 28‐year‐old cannabis using male with his first contact with psychiatric care because of mood instability, bizarre behavior, and poor ability to carry out activities of daily living. Hypercalcemia was identified, and a subsequent endocrine workup confirmed PHPT. After parathyroidectomy, there was no longer any need for antipsychotic or other psychotropic medications; the report emphasizes the importance of considering organic causes, such as hyperparathyroidism, in patients presenting with psychotic‐like symptoms, including in the setting of substance use disorder. Prompt recognition and appropriate management of the underlying condition are crucial for optimizing patient outcomes.
Time to Reach Full Enteral Feeding and Its Predictors among Very Low Birth Weight Neonates Admitted in the Neonatal Intensive Care Unit: A Follow‐Up Cohort Study
Authors: Getahun Belay Alemayehu , Mulatu Sileshi , Workie Hailemariam Mekonnen
Published: June 2024

Background. Feeding is crucial for very low birth weight neonates to grow and develop properly. This study aims to determine the time to achieve full enteral feeding and predictors among neonates admitted at Felege Hiwot Comprehensive Specialized Hospital. Methods. An institutional retrospective follow‐up study design was conducted among 332 very low birth weight neonates from July 1, 2018, to June 30, 2021. Samples were selected through a computer‐generated simple random sampling method, and the data were entered into Epi data version 4.6 and then exported to STATA version 16 for analysis. Kaplan–Meier with the log‐rank test was used to test for the presence of difference in survival among predictor variables. Model goodness of fit and assumptions were checked by the Cox–Snell residual and the global test, respectively. Variables with p value <0.25 in the bi‐variable analysis were fitted to the multivariable Cox‐proportional hazard model. Finally, the adjusted hazard ratio (AHR) with 95% CI was computed, and variables with a p value less than 0.05 in the multivariable Cox regression analysis were considered significant predictors of time to reach full enteral feeding. Results. A total of 332 neonates were followed for 2,132 person days of risk time and 167 (50.3%) of very low birth weight neonates started full enteral feeding. The overall incidence rate of full enteral feeding was 7.8 per 100 person day observations. The median survival time was 7 days. Very low birth weight neonates delivered from pregnancy‐induced hypertension‐free mothers (AHR: 2.1; 95% CI: 1.12, 3.94), gestational age of ≥33 weeks (AHR: 5,; 95% CI: 2.29, 11.13), kangaroo mother care initiated (AHR: 1.4; 95% CI: 1.01, 2.00), avoiding prefeed residual aspiration (AHR: 1.42; 95% CI: 1.002–2.03), and early enteral feeding (AHR: 1.5; 95% CI: 1.03, 2.35) were significant predictors of full enteral feeding. Conclusions. According to this study, the time to achieve full enteral feeding was relatively short. Therefore, healthcare professionals should emphasize achieving full enteral feeding and address hindering factors to save the lives of VLBW neonates.

Phenotypic Spectrum of Subclinical Sarcomere-Related Hypertrophic Cardiomyopathy and Transition to Overt Disease
Authors: Topriceanu Constantin-Cristian , Moon James C. , Axelsson Raja Anna , Captur Gabriella , Ho Carolyn Y.
Published: June 2024

Genetic hypertrophic cardiomyopathy (HCM) is classically caused by pathogenic/likely pathogenic variants in sarcomere genes (G+). Currently, HCM is diagnosed if there is unexplained left ventricular (LV) hypertrophy with LV wall thickness ≥15 mm in probands or ≥13 mm in at-risk relatives. Although LV hypertrophy is a key feature, this binary metric does not encompass the full constellation of phenotypic features, particularly in the subclinical stage of the disease. Subtle phenotypic manifestations can be identified in sarcomere variant carriers with normal LV wall thickness, before diagnosis with HCM (G+/LV hypertrophy−; subclinical HCM). We conducted a systematic review to summarize current knowledge about the phenotypic spectrum of subclinical HCM and factors influencing penetrance and expressivity. Although the mechanisms driving the development of LV hypertrophy are yet to be elucidated, activation of profibrotic pathways, impaired relaxation, abnormal Ca
2+
signaling, altered myocardial energetics, and microvascular dysfunction have all been identified in subclinical HCM. Progression from subclinical to clinically overt HCM may be more likely if early phenotypic manifestations are present, including ECG abnormalities, longer mitral valve leaflets, lower global E’ velocities on Doppler echocardiography, and higher serum N-terminal propeptide of B-type natriuretic peptide. Longitudinal studies of variant carriers are critically needed to improve our understanding of penetrance, characterize the transition to disease, identify risk predictors of phenotypic evolution, and guide the development of novel treatment strategies aimed at influencing disease trajectory.

Published: June 2024

During our investigation of the genetic and morphological variation within the distribution range of Paepalanthus calvus, we observed that specimens from Juiz de Fora municipality, Minas Gerais (Brazil) were morphologically divergent. Through genome-wide analyses using MIG-seq and detailed morphological comparisons, we were able to establish consistent differences between P. calvus and the Juiz de Fora specimens, which supported the recognition of a new species, Paepalanthus salimenae sp. nov. This new species is primarily distinguished by the narrow leaves; trichomes on the leaves, spathes, and scapes; densely pilose involucral bracts; and the tufted apex of some floral organs. Paepalanthus salimenae exhibits low genetic diversity and strong population structure. A preliminary conservation risk assessment suggests this species as Critically Endangered, highlighting the urgent need for conservation efforts to protect its habitat and intraspecific diversity. We provide photographs, line drawings and additional commentaries on the distribution, habitat, and morphological affinities of P. salimenae to congeneric taxa.
Revalidation of the termitophilous genus Ceratoxenus Mann and description of two new species from the Neotropical region (Coleoptera: Staphylinidae: Aleocharinae: Corotocini)
Authors: MORENO CARLOS , ZILBERMAN BRUNO
Published: June 2024

Termitogastrina is a subtribe of termitophilous rove beetles distributed mostly across Neotropical and Afrotropical regions. In 1923, William M. Mann established the genera Ceratoxenus and Xenopelta from material collected by Alfred E. Emerson in Guyana. Nine years later, Emerson himself synonymized the genera, in what seems to be a result from the misidentification of specimens. In this work, we revalidate the genus Ceratoxenus, provide its redescription and a taxonomical key for the species, along with a comparative diagnosis with the genus Xenopelta. Additionally, two new species of Ceratoxenus are described: C. akerata sp. nov. and C. inflatus sp. nov., respectively, from Panama and Guyana. This paper also marks a new record for the genus Ceratoxenus for Panama.
Distribution of the mysterious Chevron Crickets Melanabropsis Wang & Liu, 2020, with a remarkable new species from Hainan, China (Orthoptera: Anostostomatidae: Anabropsini)
Authors: YIN ZI-XU
Published: June 2024

Melanabropsis is a rare genus of Chevron Crickets from East Asia. In this study, Melanabropsis nightfury sp. nov. is described from Hainan Island in China. The new species is the first macropterous species belonging to the genus Melanabropsis, distinctly different from other species of the genus, which are all micropterous. Based on the data of the new species and records on iNaturalist, a suitability distribution map of the genus is generated using the Maxent model. The results indicate that this genus is primarily distributed in islands and mountains with small temperature differences and high precipitation. Taiwan Island in China shows high potential for distribution. Type specimens are deposited in the Museum of Biology, East China Normal University.
Studying Factorial Invariance With Nominal Items: A Note on a Latent Variable Modeling Procedure
Authors: Raykov Tenko
Published: June 2024

A latent variable modeling procedure for studying factorial invariance and differential item functioning for multi-component measuring instruments with nominal items is discussed. The method is based on a multiple testing approach utilizing the false discovery rate concept and likelihood ratio tests. The procedure complements the Revuelta, Franco-Martinez, and Ximenez approach to factorial invariance examination, and permits localization of individual invariance violations. The outlined method does not require the selection of a reference observed variable and is illustrated with empirical data.
PIEZO1 Promotes Odontoblast-Mediated Reactionary Dentinogenesis via SEMA3A

Published: June 2024

Located at the interface of the dentin–pulp complex, the odontoblasts are specialized cells responsible for dentin synthesis and nociceptive signal detection in response to external stimuli. Recent studies have shown that the mechanosensitive ion channel PIEZO1 is involved in bone formation and remodeling through the influx of calcium ions, and it is abundantly expressed in odontoblasts. However, the specific role of PIEZO1 in reactionary dentinogenesis and the underlying mechanisms remain elusive. In this study, we found intense PIEZO1 expression in the plasma membrane and cytoplasm of odontoblasts in healthy human third molars, mouse mandibular molars, and human odontoblast-like cells (hOBLCs). In hOBLCs, PIEZO1 positively regulated DSPP, DMP1, and COL1A1 expression through the Ca2+/PI3K-Akt/SEMA3A signaling pathway. In addition, exogenous SEMA3A supplementation effectively reversed reduced mineralization capacity in PIEZO1-knockdown hOBLCs. In vivo, Piezo1 expression peaked at day 7 and returned to baseline at day 21 in a wild-type mice dentin injury model, with Sema3a presenting a similar expression pattern. To investigate the specific role of PIEZO1 in odontoblast-mediated reactionary dentinogenesis, mice with a conditional knockout of Piezo1 in odontoblasts were generated, and no significant differences in teeth phenotypes were observed between the control and conditional knockout ( cKO) mice. Nevertheless, cKO mice exhibited reduced reactionary dentin formation and decreased Sema3a and Dsp positive staining after dentin injury, indicating impaired dental pulp repair by odontoblasts. In summary, these findings suggest that PIEZO1 enhances the mineralization capacity of hOBLCs in vitro via the Ca2+/PI3K-Akt/SEMA3A signaling pathway and contributes to reactionary dentinogenesis in vivo.
Beyond the Company Carpool: Disadvantage and Informal Automobile Sharing Within and Between U.S. Households
Authors: Paul Julene
Published: June 2024

Planners increasingly recognize connections between traveler constraints, automobile access, and travel behavior. The limited ability to travel via car—for economic or other reasons—greatly reduces mobility for many Americans, who overwhelmingly rely on automobiles for access. Yet public policy efforts to reduce excessive automobile travel often prioritize public transit, ignoring the high rates of private automobile sharing among U.S. travelers. Relatedly, few researchers have studied informal sharing and its relationship with traveler disadvantage, particularly for noncommute trips. To address this research gap, I analyze U.S. trip diary data from 2017. I use multinomial probit modeling to explore the relationship between disadvantage and informal automobile sharing. My definition of disadvantage includes people who have low incomes, travel-limiting physical conditions, and/or limited automobile access. I define several categories of informal automobile sharing to account for different dimensions of interhousehold and intrahousehold sharing. I find that transportation disadvantage is associated with most types of informal sharing, particularly borrowing cars and receiving rides from nonhousehold members. However, trip purpose—particularly noncommute trips—predicts the choice to share better than disadvantage does. Further, trip purpose has a stronger association with sharing among nondisadvantaged travelers. These findings suggest that informal sharing benefits disadvantaged travelers, but social and situational contexts also influence decisions to share transportation. I recommend policies to enhance automobile-based access for low-income travelers, including subsidies for carshare, ridehail, and private car ownership.
Environmentally-friendly solvent pulping and grafting strategies for better foamability of poly(lactic acid)/agricultural waste biocomposites

Published: June 2024

In this study, the foamability of poly (lactic acid) (PLA) through a continuous extrusion process was enhanced by using an agricultural waste, environmentally friendly pulping methods, and reactive compatibilization of the lignocellulosic filler with matrix in the extrusion flow field. Both applied solvent-pulping methods by using chemicals with low safety and toxicity risks were considerably successful in purifying the micron-sized cellulosic fibers of rice straw (RS). The interface of PLA matrix with RS pulp fibers was modified by applying reactive compatibilizers containing maleic anhydride (MA) and epoxy functional groups. Both compatibilizers had the ability to simultaneously react with the hydroxyl groups of RS pulp fibers and end groups of PLA chains during the melt-compounding process. As a result of RS pulping and PLA/RS pulp compatibilizing reactions, the processability of PLA in an extrusion foaming process was substantially enhanced, in a way that the void fraction and cell density of PLA foam increased more than seven and two times, respectively. The extruded lightweight all-green biocomposite foams can be applied in construction and packaging applications.
What Will People Think? How College Students Evaluate Bystander Intervention Behavior
Authors: Clay-Warner Jody , Tinkler Justine , Groh Sarah M. , Smith Kylie M. , Potter Sharyn
Published: June 2024

Many colleges utilize bystander intervention programs to address gender-based violence. The goal of these programs is to help students overcome barriers to intervention, including evaluation inhibition, which occurs when bystanders expect to be viewed negatively for intervening. We have limited information, though, on how college students evaluate bystanders who intervene. Specifically, we do not know whether evaluations of bystanders who engage in different levels of intervention vary across situations or how men and women who intervene similarly are evaluated. Without this information, it is difficult to design prevention programs that help bystanders overcome evaluation inhibition. To gather this information, we conducted a vignette experiment with college student participants ( n = 82). We specifically examined how students evaluated the reasonableness of male and female bystanders who engaged in different behaviors (direct intervention and threatening to tell an authority, direct intervention only, indirect intervention, doing nothing) across four situations (assault at a party, workplace harassment, harassment by a teaching assistant, and intimate partner violence). Analyses of variance found that there was situational variability in how the bystander is evaluated for different intervention tactics, though bystanders who did nothing were always evaluated the most negatively. Bystander’s gender, however, did not affect evaluations, suggesting that intervention expectations for men and women are similar. These results indicate that while there is an underlying norm supportive of intervention behavior, situational characteristics influence whether college students think it is reasonable to call authorities, confront the perpetrator, or engage in indirect intervention. The central implication of this study is that bystander intervention training should provide opportunities for students to practice intervention behaviors across a wide variety of situations of gender-based violence in order build up their store of intervention tactics, thus increasing their ability to overcome evaluation inhibition.
Postoperative Medial Malleolar Fractures in Total Ankle Replacement Are Associated With Decreased Medial Malleolar Width and Varus Malalignment: A Case-Control Study

Published: June 2024

Background:

There are limited data regarding risk factors associated with periprosthetic medial malleolar fractures in total ankle arthroplasty (TAA). This case-control study aimed to identify the risk factors and analyze the effect of prophylactic screw fixation in preventing a medial malleolar fracture after TAA.

Methods:

A case-control study was conducted on 149 patients who underwent primary TAA. Twenty patients with postoperative medial malleolar fractures >4 weeks postoperatively (cases) were identified. An additional 129 patients (controls) were randomly selected from the TAA database. Radiographic evaluation included tibial component coronal alignment and postoperative medial malleolar width. Demographics and radiographic variables were compared between cohorts. Logistic regression was used to investigate the association between medial malleolar fracture and postoperative coronal alignment, medial malleolar width, and prophylactic fixation of the medial malleolus.

Results:

Mean (SD) medial malleolar width was significantly smaller in the fracture cohort (8.52 mm [1.6]) than in the control group (11.78 mm [1.74]) ( P < .001). Mean (SD) tibial component coronal alignment was 92.17 degrees (2.77) in the fracture cohort and 90.21 degrees (1.66) in the control group ( P = .002). Regression analysis identified a significant negative association between postoperative medial malleolar width and the probability of fracture (OR = 0.06, 95% CI 0.01, 0.26, P < .001). Varus malalignment of the tibial component was positively associated with the probability of fracture (OR = 1.90, 95% CI 1.27, 2.86, P = .002). Prophylactic screw fixation resulted in more than 90% reduction in the odds of a fracture (OR = 0.04, 95% CI 0.01, 0.45, P = .01). ROC curve analysis determined a medial malleolar width of 10.3 mm as a potential threshold for predicting fracture.

Conclusion:

Decreased medial malleolar width and postoperative varus malalignment were associated with an increased risk of postoperative medial malleolar fracture. Therefore, surgeons should consider prophylactic screw fixation in patients with a medial malleolar width <10.3 mm or at risk of postoperative varus deformity.
Steady Hand at the Wheel: How Perceived Movement Influences Consumer Responses to Brand Failures
Authors: Boman Laura , An Lam , Urumutta Hewage Ganga S. , Hasford Jonathan
Published: June 2024

Paratextual communication methods, such as the use of emojis and other visual messaging cues, offer firms a unique opportunity to repair relationships with consumers after brand failures. The current research demonstrates that visual messaging cues associated with lower perceived movement lead to greater brand loyalty relative to more dynamic cues in response to brand failure. Across five studies, we show that lower perceived movement in visual messaging cues leads to more favorable consumer outcomes (e.g., subsequent real choice behavior and brand loyalty intentions). This effect is mediated by brand trust. Furthermore, we examine theoretically and practically relevant boundary conditions. The findings presented offer theoretical contributions to research on visual communication cues in brand recovery contexts. Additionally, the current research provides managerially relevant insights for communication strategies during recovery.
Assessing the economic effects of investment in smart tourism platform
Authors: Lee Hyunae , Koo Chulmo , Chung Namho
Published: June 2024

This study assesses the economic impact of Smart Tourism Platform (STP) projects in Seoul. We begin by outlining the architecture of STP, which comprises seven distinct layers, to deepen our understanding. Next, we analyze their economic effects using a four-step approach that includes Delphi surveys and the updating of Seoul’s 2015 national input-output table to a 2021 regional version through RAS and location quotient (LQ) techniques. Our findings indicate that a 2.9 billion KRW investment in STP projects creates about 3.8 billion KRW in production effects across Seoul’s industries, which is expected to generate income effects of 1.7 billion KRW, value-added effects of 2.4 billion KRW, and jobs for around 55 individuals. The insights gained from this research aim to further the understanding of STPs, providing valuable guidance for policymakers and industry stakeholders.
Queer media in the age of streaming video
Authors: Monaghan Whitney
Published: June 2024

This article contributes to an emerging field of research on the classification and organisation of film and television on streaming video platforms. While scholarship has begun to grapple with the complexities of the streaming video landscape, critical frameworks have yet to be established for examining issues of LGBTIQA+ inclusion in this context. This article explores questions about what queer media is in the streaming video era and how is this shaped by the information practices of streaming video services. Classification and organisation of titles is a significant factor in the discoverability of content on streaming video platforms. In the context of queer media, classification practices also impact the visibility of marginalised LGBTIQA+ identities, communities, and cultures. Beyond this, the categorisation practices of streaming video providers play a significant role in shaping and communicating cultural values about queer media. From an Australian vantage point, this article maps the contours of queer media in the streaming video environment, focusing on Subscription Video on Demand (SVOD) and Broadcast Video on Demand (BVOD) services. By investigating the categories that streaming video providers use to organise and highlight LGBTIQA+ film and television, this article identifies how queer media is defined as a cultural category through use of labels such as ‘pride’, the categories and subcategories that approach queer media as a constellation of niche interests, and an underlying emphasis on ‘good’ characters and positive LGBTIQA+ narratives.
Beyond the Rhetoric of Revanchism Towards the Metropolitan Core: An Analysis of Symbolic Representations of Milan From Its Peripheries
Authors: Morelli Niccolò
Published: June 2024

Socio-political research has shown that in metropolitan peripheries, populist parties have gained significant support. This is because these parties capitalise on a widespread feeling of exclusion, leading to a revanchist social representation of affluent metropolitan centres. This article contributes to the debate on metropolitan dynamics by exploring the social representations of the centre–periphery relationship, showing how symbolic representations play a role in shaping codes of action and revanchism alone is insufficient to understand the core–periphery relationship. Four suburbs with similar socioeconomic characteristics in the functional urban area of Milan were selected. Milan is the most important Italian metropolis, and it has a relevant socio-political fracture. Semi-structured interviews were carried out to analyse the cultural meanings of living on the periphery among local leaders. The metropolitan centre is perceived as necessary, evoking ‘efficient’ representations; however, these peripheral contexts are meaningful places of belonging. This article shows that an analysis of the dynamics at work at the metropolitan level should consider peripheral contexts.
How do guests evaluate eco-certified hotels? An analysis of guests’ reviews of Portuguese hotels
Authors: Pacheco Luís , Ramazanova Makhabbat , Carvalho João M. S. , Nogueira Sónia , Durão Marília
Published: June 2024

User-generated content and online reviews have become a prominent source of information for tourists in the last couple of decades. At the same time, hospitality firms show an increasing concern with environmental practices, in line with customers’ changes of attitude and awareness of their environmental footprint. This paper analyses the content of reviews posted on TripAdvisor by guests staying in a large sample of environmentally certified hotels. The objective is to find out if sustainability concerns are present in guests’ reviews and identify the most important sustainability attributes. Using the Maxqda and Leximancer software, 1748 reviews from 95 Portuguese hotels were analysed; the content analysis evidences that guests’ predominant themes regarding their experiences are mostly common and independent of the category, average review, or type of travel. Eco-issues are primarily absent from the reviews. Although all analysed hotels are ‘eco-certified’, that label does not seem to be associated with guests’ attitudes and concerns. The results have relevant implications for hospitality managers.

Many communities in southwestern Madagascar rely on a mix of foraging, fishing, farming, and herding, with cattle central to local cultures, rituals, and intergenerational wealth transfer. Today these livelihoods are critically threatened by the intensifying effects of climate change and biodiversity loss. Improved understanding of ancient community-environment dynamics can help identify pathways to livelihood sustainability. Multidisciplinary approaches have great potential to improve our understanding of human-environment interactions across spatio-temporal scales. We combine archaeological survey data, oral history interviews, and high-resolution multispectral PlanetScope imagery to explore 400 years of human-environment interaction in the Namonte Basin. Our analysis reveals that settlement and land-use led to significant changes in the region’s ecology, both during periods of occupation and after settlement abandonment. Human activity over this period may have stabilized vegetative systems, whereby seasonal changes in vegetative health were reduced compared to surrounding locations. These ecological legacies may have buffered communities against unpredictable climate challenges.

This study addresses the critical need for enhanced vibration control and standardization in electric motors, pivotal to the operational efficiency of electric vehicles and thus, environmental sustainability. Recognizing the gap in unified standards for managing machine vibration, we propose a novel, integrated framework combining advanced vibrodiagnostic techniques and rigorous standardization processes. Our methodology involves a detailed analysis of existing vibration control practices, identifying deficiencies in current standards, and presenting an improved, comprehensive guideline tailored to electric motors’ unique requirements in transportation applications. The innovation of our approach lies in its dual focus on technical precision and environmental sustainability, offering a significant leap forward in vibrodiagnostics. We demonstrate the framework’s practical value through its potential to revolutionize electric motor maintenance strategies, enhance machine longevity, and reduce environmental impact. This research contributes to the broader goals of reducing greenhouse gas emissions and advancing sustainable transportation, emphasizing the importance of vibration control standards in achieving energy efficiency and reliability in electric transport systems.

Published: June 2024

Very few methods are available for predicting the secondary fragment velocity and secondary fragment production of grouted and unreinforced concrete masonry unit (FGUR CMU) walls when subjected to blast loading. A novel energy-based methodology is developed that calculates the secondary fragment velocity of an unreinforced fully grouted concrete masonry unit (CMU) wall under blast loading. The computationally efficient, engineering-level methodology was originally derived for fragment velocity calculation of unreinforced ungrouted CMU walls. Existing approaches often require large computational resources or fail to predict secondary fragment velocity accurately; this approach calculates fragment velocities with minimal computational effort. The applicability of this analytical model to unreinforced fully grouted CMU walls is discussed. The selection of a resistance function and assumptions about fragment behavior are examined. Velocity calculations throughout wall fragmentation are compared to velocities from quarter-scale and full-scale experiments and reasonable agreement is observed.

Objective

Understanding biopsychosocial contributions to a sensitised pain system is a key target of many pain management programs. The ‘Protectometer’ is a freely available educational tool that guides people with chronic pain to explore their personal threats and reassurances, identifying them as ‘DIMs’ (danger in me) or ‘SIMs’ (safety in me), to guide personalised pain management. This study aimed to explore common types of DIMs and SIMs, and examine differences between adults and young people.

Materials and Methods

A retrospective qualitative study was conducted. Written DIMs ( n = 504) and SIMs ( n = 711) were collected from 96 participants with chronic pain (77 adults aged 18–85 years; 19 young people aged 9–17 years) across 15 multidisciplinary pain management groups. DIMs and SIMs were transcribed and analysed using deductive content analysis.

Results

Four overarching themes were identified: ‘Engaging with the environment’, ‘In my body’, ‘My emotional health’, and ‘Activities and behaviours’. Similarities in SIMs were found, with the greatest proportion of SIMs in the social domain (49% adults; 47% young people). While adult DIMs were fairly evenly spread across the biological (37%), psychological (27%) and social domains (36%), young people’s DIMs were predominantly in the psychological (44%) and social (43%) domains.

Discussion

These findings provide insights into common threats and reassurances people in pain perceive, and revealed age-related differences in biopsychosocial contributions to pain and pain relief. Findings also highlight the importance of social-based interventions as part of pain management therapies for both adults and young people.

This study aimed to uncover the trend of mental health in China over the years and the influence of related social factors. This study employed a cross-temporal meta-analysis (CTMA). The study analyzed 182 studies from 1993 to 2017. A total of 83,603 participants were included in 182 studies. Symptom Checklist-90 (SCL-90) Scale. From 1993 to 2001 and from 2004 to 2017, the scores for each dimension for mental health of older adults were relatively stable, and the absolute value of the effect size was between 0.02 and 0.62. From 2001 to 2003 and from 2003 to 2004, the scores of each dimension of older adults changed greatly. From 2001 to 2003, the total mean score of SCL-90 and the scores of different dimensions in older adults showed a rapidly decreasing trend, with the d ranging from −0.40 to −0.93. From 2003 to 2004, the scores of all dimensions in SCL-90 showed a trend of sharp increase, and the d of each dimension was 0.40 to 0.89. The mental health status of the older adults is declining as a whole and has a large fluctuation from 2001 to 2004 various social development indicators, including Gross Domestic Product (GDP), per capita, divorce rate, unemployment rate, and Engel’s coefficient, demonstrated a significant correlation with mental health status

Published: June 2024

This outstanding image article delves into the intriguing instance of a 42-year-old woman grappling with persistent lumbosacral pain over 13 years, accentuated postpartum. Electromyography (EMG) and magnetic resonance imaging (MRI) uncovered sciatic endometriosis. The rarity of this manifestation prompted a biopsy for anatomopathological confirmation, underscoring the complexity of the case. Despite unsuccessful attempts with various interventions, the administration of gonadotropin-releasing hormone (GnRH) analogs led to significant improvement, emphasizing the efficacy of tailored treatments for uncommon endometriosis presentations. This case underscores the pivotal role of advanced imaging, particularly MRI, in precise diagnosis and personalized treatment planning, showcasing the transformative impact of well-tailored interventions on the intricate facets of endometriosis. The collaborative efforts of medical professionals, guided by imaging insights, not only alleviate symptoms but also contribute substantially to preserving neurological integrity, emphasizing the profound importance of tailored treatment in enhancing overall well-being.

Background:

Due to modern therapies, survival in metastatic renal cell carcinoma (mRCC) has been significantly prolonged. Nevertheless, patients suffering from advanced disease often present with severe symptoms. Early integration of palliative care into anti-cancer treatment has been shown to improve quality of life and may even prolong survival. Therefore, it is recommended to offer palliative care to patients with complex symptoms at the beginning of an advanced disease stage. To our knowledge, so far, no study has been conducted to examine the role of palliative care in patients with mRCC.

Objectives:

This study aimed to assess the symptom burden and quality of life before and after an inpatient palliative care treatment.

Design:

The study design is a retrospective observational study.

Methods:

We included patients with mRCC, who were admitted to our palliative care unit between 2011 and 2017 due to severe symptoms. The symptom burden was assessed at admission, throughout treatment, and at discharge. The evaluation consisted of the palliative care base assessment and daily documentation of relevant symptoms.

Results:

We evaluated 110 hospitalizations of 58 RCC patients. On average, patients were admitted to the palliative care unit 7 years after initial diagnosis (range 1–305 months). The median age was 70.5 years, 69% of the patients were male, 3% female. The main causes for admission were pain (52%) and dyspnea (26%), and the most frequent patient-reported symptoms were fatigue/exhaustion (87%), weakness (83%), and need for assistance with activities of daily living (83%). Multidisciplinary palliative care treatment led to a significant reduction in the median minimal documentation system (MIDOS) symptom score (15.6–9.9, p < 0.001), the median numeric pain rating scale (3–0, p < 0.001), and a significant reduction in mean ratings of the distress thermometer (5.5–3.1, p = 0.016).

Conclusion:

Our analysis shows that the integration of palliative care treatment is effective throughout the disease in mRCC and could measurably reduce the symptom burden in our patient population. Palliative care should not be equated with end-of-life care but should rather be integrated throughout advanced disease, particularly as soon as a cure is impossible.

Published: June 2024

Lung cancer has been mentioned as the first and second most prevalent cancer among males and females worldwide, respectively since conventional approaches do not have enough efficiency in its suppression. Therefore, a biocompatible and efficient polylactic-co-glycolic acid (PLGA: P)- poly-ε-caprolactone (PCL: P) copolymer was fabricated for delivery of relatively insoluble curcumin (Cur) to A549 lung cancer cells. Next, the physicochemical aspects of the synthesized nanobeads were characterized by applying analytical sets, including FT-IR, DLS, TEM, and TGA as nano-metric size (20–45 nm) and 1.29% of Cur entrapment efficiency were determined for P-P-Cur nano-beads. Thereafter, a controlled (5% within 2 h at pH 7.4) and pH-sensitive (nearly 50% within 4 h at pH 5.0) drug release manner was observed for P-P-Cur nanobeads. Thereafter, biomedical assays were conducted for the cancer suppression ability of nanobeads. 41% cell viability after 24 h of treatment with 200 nM concentration and 7.55% cell cycle arrest at 5 h of post-treatment with 100 nM (IC50) concentration were attained for P-P-Cur. Also, 7-fold increase and 2-fold decrease in the expressions of Caspase-9 (apoptotic gene) and Bcl2 (anti-apoptotic gene) were observed which have further approved the cancer inhibition potency of the P-P-Cur sample. The cellular uptake results indicated 91% internalization in A549 cells while it was less than 1% for the pure Cur. These data have demonstrated that P-P-Cur can use as a biocompatible drug delivery system for Cur and treatment of lung cancer.
