Hydrodynamic Analysis in Marine Operations: A Preprocessing and Postprocessing Tool
Authors: Gullaksen Joannes
Published: October 2022

A pre- & post-processor for modelling and analysis of marine operations to support hydrodynamic subsea installation analysis is presented in this paper. The pre-processor is automating the input model for static analysis, that also includes preliminary estimates of load effects as basis for product configuration and input parameters to dynamic analysis models, including product specific capacities and limit state criteria directly related to installation operation. Subsea installation operations will normally be weather restricted operations demanding a thorough evaluation of relevant environmental conditions. Short-term wave conditions are described by a stochastic method using wave spectra, or the deterministic design wave method. Statistical distributions are used to describe long-term and extreme value conditions, or scatter diagrams for governing sea state parameters. Joint wave-current distributions of parameters and corresponding surfaces for given exceedance probability levels are considered. The analyses establish relevant installation parameters required in order to carry out the installation operations in a safe manner. Static analysis is also used for curve stability analysis, on-bottom stability analysis, recovery analysis, J-tube pull-in analysis, tie-in analysis and sensitivity analysis. The post-processor is used to display and review the static and dynamic analysis results, including compliance with the given limit state criteria under the relevant limiting weather conditions of each operation. This also includes easy comprehension of data supported by tools that provides the ability to easily view appropriate results quantities on all model objects. Important for a fast analysis turnaround is the ability to process the data and support the user in getting the necessary information to understand the model’s hydrodynamic behaviour.
A Comparison of Approaches for Modelling Walk-to-Work Gangway Access
Authors: Moverley Smith Ben , Middleditch Ben , Thies Philipp
Published: October 2022

The accessibility of offshore wind farms is a key parameter when considering the cost of the operations and maintenance (O&M) of wind farm assets. Indeed, the weather limits for accessing wind turbines is a critical input in many tools which seek to simulate and optimize O&M activities. To refine this input, numerical modelling has been performed previously to perform workability analyses for service operation vessels with motion compensated walk to work gangways. However, previous modelling effort has employed an implicit representation of a gangway, which does not consider the relative motion of gangway subcomponents. In this study, two different gangway representations are employed for a numerical simulation of a transfer procedure between a service operation vessel and an offshore turbine. Comparison of the limiting wave heights given by analysis of the implicit and explicit representation of the gangway shows a difference when considering waves incident toward the vessel from the foundation location, with much lower wave heights allowed by the complex representation. Applying this difference in operational wave heights to a case study location leads to a difference in overall site availability of over 9%. The implications of these findings on future accessibility analysis and foundation design are discussed.
GPU-Accelerated High-Order Spectral - OpenFOAM Coupled Model for Numerical Analysis of Ship Motion in Nonlinear Waves
Authors: My Ha Dao , Xin Lu , Quang Tuyen Le
Published: October 2022

The High-Order Spectral (HOS) has been a desirable method for studies of fully nonlinear wave propagation over very large areas. To handle a long-standing classical problem of surface waves-current-structure interaction, we introduce several major developments. We first extend HOS-based wave model to include a prescribed steady current. We then migrate the code to the GPU platform to speed-up the simulation. The GPU-accelerated HOS solver is then coupled with a CPU-based CFD multiphase solver in OpenFOAM to account for the FSI. The coupled solver is demonstrated for simulations wave-current interactions. Lastly, the near and far field coupling solver is applied to a simulation of the seakeeping response of a cruising ship hull in head wave condition.
Prediction and Benchmarking of a Nearly Horizontal Flowline Slug Flow
Authors: Mesa Jose D. , Gao Haijing , Constantinides Yiannis
Published: October 2022

In recent years the oil and gas industry has increased its attention to slugging flow-induced vibration challenges due to their effect in deep and shallow water assets operations. Risers, subsea pipelines and jumpers are checked to ensure that the predicted slugging events based on the well’s production life do not consume excessive fatigue capacity and provide a suitable design basis. For shallow water gas production wells, the fatigue generated due to slug events can be a governing case for pipeline and riser design. Due to the complexity of the internal-flow physics, numerical simulations are typically employed to predict the number of expected slug events and characteristics during the design phase.

One well-known limitation in commercial flow simulation packages is the prediction uncertainty for slug flows in risers and pipelines. The abrupt changes in the pipeline content density and asset configuration can promote the generation of slugs, increasing the probability of underpredicting the number of events through the asset service life and reducing the accuracy of the slug characteristics prediction. Furthermore, there is no standardized methodology for the slug analysis required in the industry or regulatory agencies.

This study documents the current limitations of the industry practices and state-of-the-art methods to predict slug flow that can affect operations and integrity of assets. The first industry flow-induced vibration experiments that couples the internal flow with its structural response are presented. The experimental data collected in this study on slugging characteristics are benchmarked against predictions from flow simulators to address the modeling uncertainties of slug characteristics. The benchmarking study further explains the multiphase model limitations and prediction bias for the slugging phenomenon in a pipeline.

As part of the study, we have developed a method for obtaining a single-layer Ti2CTx MXene by the interaction of Ti2AlC with a mixture of hydrochloric acid and sodium fluoride followed by delamination using a tetramethylammonium hydroxide solution and ultrasonic exposure. The obtained stable aqueous dispersion of Ti2CTx has been applied by microplotter printing onto a specialized sensor chip, which has been dried at a temperature of 150°C under reduced pressure. The coating has been studied using modern physicochemical methods of analysis. According to the data of X-ray spectral elemental microanalysis, the ratio n(Ti) : n(F + Cl) = 2 : (0.82–0.85), n(F) : n(Cl) ≈ 6 : 4; aluminum impurity does not exceed 1.5–2.0%. Data have been obtained on the local electrophysical properties of the Ti2CTx coating: on the value of the electron work function from the surface of the material, the distribution of charge carriers, and the capacitance gradient of the “probe tip–sample microregion” capacitor. For the first time, at an operating temperature of 30°C, extremely high chemoresistive responses of the Ti2CTx receptor layer to the content of 1 and 5% oxygen in nitrogen have been determined, which amounted to 8.6 and >276, respectively.
Can Defence be assured that future civilian specialty training programmes will produce suitably qualified and experienced military doctors?
Authors: McPhail Stuart
Published: October 2022

UK Defence’s doctors receive the majority of their pre-accreditation clinical training within the National Health Service’s (NHS) specialty training programmes. These are designed primarily to serve the needs of a civilian patient population and are undergoing changes. Examination of these changes in relation to the training requirements of Defence’s doctors, suggests that future NHS training programmes present both opportunity and threat to the provision of competent military consultants and general practitioners (GPs). Opportunity to more easily integrate military-specific courses, experience and modules will be present in the form of curricula that are more receptive to change and more flexible with respect to time out of programme. This offers definite advantage in terms of ability to robustly equip military doctors with the skills required to serve their future patients. Narrowing scopes of practice and a reduction in acute care exposure for GPs are potential future threats.
The Impact of E-Commerce and Ride Hailing on Emissions from Shopping-Related Transport: A Case Study of the Shopping Habits of University Students from Ningbo University
Authors: Sun Yu , Lian Feng , Yang Zhongzhen
Published: October 2022

To clarify the impact of new transport services on consumers’ shopping behaviors and shopping-related transport emissions, a back-propagation neural network shopping channel choice model is established to estimate the number of times that consumers engage in online and offline shopping. A brick-and-mortar store choice model and travel mode choice model are developed, and a method to measure the quality of life of consumers is established to evaluate the impact of new transport services on shopping behaviors and the corresponding shopping transport emissions. The findings reveal that a new passenger transport service increases the number of times that consumers shop in brick-and-mortar stores and correspondingly shopping transport emissions; a new commodity transport service reduces the number of times that consumers shop in brick-and-mortar stores and in turn shopping transport emissions. In a scenario with both new commodity services and new passenger transport services, although online shopping is convenient, consumers are still willing to pay travel expenses for offline shopping; in a scenario with the new commodity transport service but without the new passenger transport service, the emissions from shopping-related transport are the lowest.
Potential Spectrum of Accompanied Penetrating Abdominal Intraperitoneal Injuries with Bowel Evisceration: Surprises Awaiting the Trauma Surgeon in Resource Limited Settings

Published: October 2022

Penetrating abdominal injuries involves violation of the peritoneal cavity and injuries to solid organs and other intraperitoneal viscera such as major blood vessels and hollow organs. Typically such injuries arise from gunshot wounds or stab wounds. With increase in crime rates and motor traffic accidents in urban areas, the trauma surgeon in civilian urban centers faces spectrum of injuries similar to his colleague in war torn areas. Potential spectrum of penetrating abdominal injuries is wide and accurate diagnosis in resource limited centers is challenging. Majority of injuries are concealed and diagnosed intraoperatively and dealt with relatively junior trauma surgeons in emergency settings in remote limited settings. Computed tomography (CT) scans and Magnetic Resonance Imaging (MRI) facilities are scarce in resource limited settings. Haemodynamic states of penetrating abdominal injuries patients presenting in emergency departments necessitate urgent surgical exploration and management with minimal room for full radiological work-up. Evisceration of bowels with unstable haemodynamic states mandate laparotomy due to wide spectrum of accompanied intraperitoneal injuries. Four cases of penetrating abdominal injuries are presented with modes of assault ranging from gunshot injuries to stab wounds with broken bottles to highlight the intra-abdominal spectrum of injuries, challenges in diagnosis and emergency managements done in a resource limited setting.

Published: October 2022

Background. Hot water extract of Sasa albomarginata (Kumazasa) leaves is commercially available and used as a dietary supplement or skincare cream. The extract possesses anti-inflammatory activity on the mouse atopic dermatitis model. To elucidate the mechanism of in vivo activity, we have studied the cellular anti-inflammatory and antioxidant activities of the extract and its constituents. Methods. Secretion of mouse and human IL-6 was measured by ELISA. ROS production was measured by a fluorescent reagent. Ultrahigh performance liquid chromatography (UHPLC)/MS was used for the ingredient analysis. Results. The Sasa albomarginata extract inhibited inflammatory mediators such as LPS-induced NO, IL-6, and ROS production in mouse monocyte leukemia RAW264.7 cells. It also inhibited iNOS, IL-6, and IL-1β expressions. Moreover, it inhibited LPS-induced IL-6 expression and production in human monocyte leukemia THP-1 cells differentiated into macrophages. The HPLC analysis of the extract revealed the existence of coumaric acid, ferulic acid, and coumaric acid methyl ester. Coumaric acid methyl ester but not coumaric acid or ferulic acid inhibited LPS-induced NO, IL-6, and ROS production in RAW264.7 cells and IL-6 production in differentiated THP-1 cells. Conclusion. The hot water extract of Sasa albomarginata leaves and one of its constituents possess cellular anti-inflammatory and antioxidant activities.

Authors: Liu Zongtai , Li Guibin , Liu Haiyan , Zhu Jiabo , Wang Dalin
Published: October 2022

Background. To establish two nomograms to quantify the diagnostic factors of lung metastasis (LM) and their role in assessing prognosis in young patients with LM osteosarcoma. Methods. A total of 618 osteosarcoma young patients from 2010 to 2015 were included from the Surveillance, Epidemiology, and End Results (SEER) database. Another 131 patients with osteosarcoma from local hospitals were also collected as an external validation set. Patients were randomized into training sets (n = 434) and validation sets (n = 184) with a ratio of 7:3. Univariate and multivariate logistic regression analyses were used to identify the risk factor for LM and were used to construct the nomogram. Risk variables for the overall survival rate of patients with LM were evaluated by Cox regression. Another nomogram was also constructed to predict survival rates. The results were validated using bootstrap resampling and retrospective research on 131 osteosarcoma young patients from 2010 to 2019 at three local hospitals. Results. There were 114 (18.45%) patients diagnosed as LM at initial diagnosis. The multivariate logistic regression analysis suggested that T stage, N stage, and bone metastasis were independent risk factors for LM in newly diagnosed young osteosarcoma patients (

). The ROC analysis revealed that area under the curve (AUC) values were 0.751, 0.821, and 0.735 in the training set, internal validation set, and external validation set, respectively, indicating good predictive discrimination. The multivariate Cox proportional hazard regression analysis suggested that age, surgery, chemotherapy, primary site, and bone metastasis were prognostic factors for young osteosarcoma patients with LM. The time-dependent ROC curves showed that the AUCs for predicting 1-year, 2-year, and 3-year survival rates were 0.817, 0.792, and 0.815 in the training set and 0.772, 0.807, and 0.804 in the internal validation set, respectively. As for the external validation set, the AUCs for predicting 1-year, 2-year, and 3-year survival rates were 0.787, 0.818, and 0.717. Conclusions. The nomograms can help clinicians strengthen their personal decision-making and can improve the prognosis of osteosarcoma patients.

Published: October 2022

Esta pesquisa buscou compreender os impactos gerados na saúde do trabalhador rural pelo uso indiscriminado de agrotóxicos e os desafios para a responsabilização no Brasil. Contrapôs-se o discurso produtivista, utilizado para ampliar cada vez mais a quantidade e variedade de agrotóxicos utilizados, e o discurso em torno da segurança e soberania alimentar e nutricional,  que busca alternativas ao modelo produtivo hegemônico. Para tanto, com uma abordagem qualitativa guiada pela dialética, utilizaram-se pesquisas bibliográficas e documentais, além de análises indiretas de dados acerca do uso e da contaminação por agrotóxicos e análises jurisprudenciais acerca da responsabilidade civil decorrente de sua má utilização. Inferiu-se que há casos de responsabilização na jurisprudência brasileira, mas que, pela natureza do dano e pela dificuldade de estabelecer o nexo causal, ela ocorre em caráter excepcional. Como consequência, revelou-se a necessidade de avançar no estudo da responsabilidade e do risco da atividade, de maneira a proteger a saúde humana, em especial a do trabalhador rural, afetado diariamente pelos impactos dos insumos químicos que é obrigado ou, no mínimo, instado a manipular.

O presente artigo apresenta uma iniciativa pouco difundida na historiografia das artes visuais. Uma mostra concebida pela fotógrafa estadunidense Nan Goldin, que vislumbrou num momento de exceção uma possibilidade de visibilizar os reflexos da epidemia na produção de diversos artistas.  Em meio à epidemia da aids, em que o preconceito e as mortes consecutivas estabeleciam duros limites à atuação, Goldin mobilizou uma síntese de profunda delicadeza. Retomar esse exemplo, nesse contexto, abre uma série de paralelos históricos que permitem compreender especificidades e recorrências. Mais do que estabelecer uma espécie de prognóstico para caminhos futuros, o artigo estimula a encontrar em exemplos históricos formas de contato com o hoje.

Memoryless Optimality: Neurons Do Not Need Adaptation to Optimally Encode Stimuli With Arbitrarily Complex Statistics
Authors: Forkosh Oren
Published: October 2022

Our neurons seem capable of handling any type of data, regardless of its scale or statistical properties. In this letter, we suggest that optimal coding may occur at the single-neuron level without requiring memory, adaptation, or evolutionary-driven fit to the stimuli. We refer to a neural circuit as optimal if it maximizes the mutual information between its inputs and outputs. We show that often encountered differentiator neurons, or neurons that respond mainly to changes in the input, are capable of using all their information capacity when handling samples of any statistical distribution. We demonstrate this optimality using both analytical methods and simulations. In addition to demonstrating the simplicity and elegance of neural processing, this result might provide a way to improve the handling of data by artificial neural networks.
Unsupervised Domain Adaptation for Extra Features in the Target Domain Using Optimal Transport
Authors: Aritake Toshimitsu , Hino Hideitsu
Published: October 2022

Domain adaptation aims to transfer knowledge of labeled instances obtained from a source domain to a target domain to fill the gap between the domains. Most domain adaptation methods assume that the source and target domains have the same dimensionality. Methods that are applicable when the number of features is different in each domain have rarely been studied, especially when no label information is given for the test data obtained from the target domain. In this letter, it is assumed that common features exist in both domains and that extra (new additional) features are observed in the target domain; hence, the dimensionality of the target domain is higher than that of the source domain. To leverage the homogeneity of the common features, the adaptation between these source and target domains is formulated as an optimal transport (OT) problem. In addition, a learning bound in the target domain for the proposed OT-based method is derived. The proposed algorithm is validated using both simulated and real-world data.
Unraveling Tragia peltata (Euphorbiaceae): taxonomy, morphology, distribution and conservation
Authors: FREIRE DE SÁ CORDEIRO WESLEY PATRÍCIO , DE MELO ANDRÉ LAURÊNIO , FERREIRA DE SALES MARGARETH , ATHIÊ-SOUZA SARAH MARIA
Published: October 2022

Tragia peltata was published by Friar José Mariano da Conceição Vellozo in 1831, with a brief description of the leaf blade and a rudimentary illustration, subsequently Müller Argoviensis measured the size leaf blade—those being the only references to this species for more than 190 years. Specimens collected from 1971 onwards from the Brazilian states of Bahia, Espírito Santo, and Rio de Janeiro were recently encountered, however, in herbaria in that country. It is therefore possible to complement the description of T. peltata, update its geographic distribution range, and determine its conservation status; the species is also lectotypified here.
A new Chiasmocleis (Anura: Microhylidae) from the eastern Guiana Shield with an amended definition of C. haddadi Peloso, Sturaro, Forlani, Gaucher, Motta, & Wheeler, 2014
Authors: FOUQUET ANTOINE , RODRIGUES MIGUEL T. , PELOSO PEDRO
Published: October 2022

The existence of an unnamed (candidate) species from French Guiana and the state of Amapá (Brazil) closely related to Chiasmocleis haddadi has been hypothesized in previous DNA-based studies. With an integrative use of genetic, morphological and acoustic data we confirm that these populations are indeed distinct from C. haddadi and all other known congeners. We herein describe and name this new species, and amend the definition of C. haddadi since the type-series and its original diagnosis included specimens of the new species. Geographically, the new species occurs eastward of its sister species C. haddadi from which it can be distinguished by having a larger body, a proportionally smaller eye and a distinct dorsal colouration. We suspect that the new species breeds in the leaf litter and that tadpoles undergo endotrophic development whereas co-occurring C. haddadi and C. hudsoni lay clutches in the leaf litter nearby standing water of temporary ponds where exotrophic tadpoles complete their development. This new species is a new addition to the already long list of animals being endemic to the easternmost part of the Guiana Shield, a region identified as a singular bioregion within Amazonia by previous research.
Foundational Needs of Forecasters for Probabilistic Winter Forecasting
Authors: Tripp Daniel D. , Trujillo-Falcón Joseph E. , Klockow-McClain Kim E. , Reeves Heather D. , Berry Kodi L. , Waldstreicher Jeff S. , Nelson James A.
Published: October 2022

This study explores forecaster perceptions of emerging needs for probabilistic forecasting of winter weather hazards through a nationwide survey disseminated to National Weather Service (NWS) forecasters. Questions addressed four relevant thematic areas: 1) messaging timelines for specific hazards, 2) modeling needs, 3) current preparedness to interpret and communicate probabilistic winter information, and 4) winter forecasting tools. The results suggest that winter hazards are messaged on varying time scales that sometimes do not match the needs of stakeholders. Most participants responded favorably to the idea of incorporating new hazard-specific regional ensemble guidance to fill gaps in the winter forecasting process. Forecasters provided recommendations for ensemble run length and output frequencies that would be needed to capture individual winter hazards. Qualitatively, forecasters expressed more difficulties communicating, rather than interpreting, probabilistic winter hazard information. Differences in training and the need for social-science-driven practices were identified as a few of the drivers limiting forecasters’ ability to provide strategic winter messaging. In the future, forecasters are looking for new winter tools to address forecasting difficulties, enhance stakeholder partnerships, and also be useful to the local community. On the regional scale, an ensemble system could potentially accommodate these needs and provide specialized guidance on timing and sensitive/high-impact winter events.

Significance Statement

Probabilistic information gives forecasters the ability to see a range of potential outcomes so that they can know how much confidence to place in the forecast. In this study, we surveyed forecasters so that we can understand how the research community can support probabilistic forecasting in winter. We found that forecasters want new technologies that help them understand hard forecast situations, improve their communication skills, and that are useful to their local communities. Most forecasters feel comfortable interpreting probabilistic information, but sometimes are not sure how to communicate it to the public. We asked forecasters to share their recommendations for new weather models and tools and we provide an overview of how the research community can support probabilistic winter forecasting efforts.
Effect of Educational Program on Knowledge, Skills, and Personal Preparedness for Disasters Among Emergency Nurses: A Quasi-Experimental Study
Authors: Al-qbelat Razan M. , Subih Maha. M. , Malak Malakeh Z.
Published: October 2022

Continuous nursing education has a significant correlation with increasing knowledge, improving skills, and personal preparedness for disasters among nurses which leads to a decrease in mortality rate and enhances the quality of care. However, there is limited literature evaluating the effect of educational programs on the knowledge, skills, and personal preparedness for disaster preparedness among emergency nurses at Arab countries including, Jordan. This study evaluated the effect of an educational program on knowledge, skills, and personal preparedness for disasters among emergency nurses. A quasi-experimental study and one-group pretest-posttest design was used. A convenience sample was adopted to recruit registered nurses who are working in emergency rooms in the private and government health sectors in Jordan (N = 50). This study was conducted between May and June 2021. The intervention included an educational program consisting of 5 topics about disasters. The participants attended this program for 8 h over 1 week via Zoom application. There were significant differences between the pre-post educational intervention for knowledge ( t = 4.79, P ≤ .001), skills ( t = 6.66, P ≤ .001), and personal preparedness ( t = 9.56, P ≤ .001) for disasters. These findings suggested the importance of implementing continuous education and training programs for emergency nurses about disasters due to increasing frequency of disasters worldwide.
Emotion regulation through music and mindfulness are associated with positive solitude differently at the second half of life
Authors: Bachman Noa , Palgi Yuval , Bodner Ehud
Published: October 2022

Mindfulness and emotion regulation through music listening are skills that share some attributes with the skill of positive solitude (PS; defined as an inner choice to dedicate time to a meaningful, enjoyable activity or experience managed by oneself, with or without the presence of others). Nevertheless, little is known about their relationship with PS in the second half of life. Hence, we recruited a convenience sample of community-dwelling adults in the second half of life ( N = 123; M = 68.63, SD = 10.99), who completed self-report measures of demographics, emotion regulation through music, mindfulness, and PS. A hierarchical linear regression demonstrated significant positive associations between emotion regulation through music listening and PS, and between mindfulness and PS. Moreover, age moderated the relationship between mindfulness and PS. This relationship was found to be positive and significant only among older adults. These findings support the study’s hypotheses and emphasize the contribution of the current research to developmental research on PS in the second half of life.
Ketch Yorlye Daun Paradise: Sense of place, heritage and belonging in Norfolk Island’s Kingston and Arthur’s Vale Historic Area
Authors: Cantillon Zelmarie , Baker Sarah
Published: October 2022

Senses of place are strongly intertwined with senses of heritage and cultural identity. Heritage places are distinctive not only for their tangible dimensions, but also the intangible qualities which give them meaning. The conservation of heritage places, however, has often emphasised the materiality of place rather than its symbolic significance. This article explores issues surrounding sense of place and heritage management through a focus on the former site of the Paradise Hotel in Norfolk Island’s Kingston and Arthur’s Vale Historic Area. Drawing on interviews and a zine co-created with Norfolk Island residents, the article unpacks various ways participants articulate connections to the Paradise via their memories and recollections of the past as well as their present interpretation of and engagement with the site. Through a localised case study, the article provides insight into transnational challenges for the relationship between sense of place, heritage value and heritage management and interpretation.

Published: October 2022

Background:

The relationship between socioeconomic status (SES) and mortality among persons with multiple sclerosis (PwMS) is poorly understood.

Objective:

To investigate the association between SES and mortality risk in PwMS.

Methods:

From health-administrative data, we identified 12,126 incident MS cases with a first demyelinating event (MS ‘onset’) occurring between 1994 and 2017. Cox proportional hazard model assessed the association between socioeconomic status quintiles (SES-Qs) at MS onset and all-cause mortality.

Results:

Lower SES-Qs were associated with higher mortality risk; adjusted hazard ratios: SES-Q1 (most deprived) =1.61 (95% confidence interval (CI) = 1.36–1.91); SES-Q2 = 1.26 (95% CI = 1.05–1.50); SES-Q3 = 1.22 (95% CI = 1.02–1.46); SES-Q4 = 1.13 (95% CI = 0.94–1.35) versus SES-Q5 (least deprived).

Conclusion:

A lower SES was associated with higher mortality risk in PwMS.

Authors: Lu Ziliang , Xu Juan , Gao Weijun , Hou Chaoping , Hao Yulin
Published: October 2022

Traditional dwelling has achieved harmony between building and climatic environment, which is one of the most significant prerequisites for sustainability. In this study, Liyuanba traditional dwellings were selected as the representative traditional dwellings in southwestern part of Qinba mountainous area, and passive design strategies extracted from traditional dwellings were utilized to improve its indoor thermal comfort. This research presents an approach in which the energy simulation, orthogonal arrays and range analysis were integrated to analyze the sensitivity of each passive parameter to overall energy-saving performance and to determine how energy consumption can be minimized by the optimal combination of them. The optimized passive strategy could reduce the annual energy consumption of the simulated dwelling by 65.1% compared with that of the original one and increase the indoor air temperature and mean radiation temperature by 4.31°C and 4.35°C in winter, respectively, meeting the requirements of the design standard for energy efficiency for rural residential buildings (GB/T50824-2013). Through the systematic study of passive parameters in the southwestern part of Qinba mountainous area, the optimal combination of passive design strategies could be utilized for the renovation of traditional dwellings to improve the building energy performance under the premise of satisfying the indoor thermal comfort.
Insights into proton pump inhibitor-induced photosensitivity: An observational study in a tertiary photobiology service
Authors: Butt Sanaa , McMullan Alexandra , Dawe Robert , Ibbotson Sally
Published: October 2022

Background:

Proton pump inhibitors (PPIs) are extensively prescribed but may cause photosensitivity and drug-induced lupus erythematosus (DILE), which can be overlooked as the drug may have been taken for years prior to presentation.

Methods:

We reviewed the clinical and investigation findings of patients diagnosed with PPI-induced photosensitivity, diagnosed through the Scottish Photobiology Service.

Results:

We report 11 patients with median age of onset 61-years and mean duration of PPI ingestion of 5-years [DILE ( n = 6), phototoxicity ( n = 3) and drug-induced solar urticaria through a lupus mechanism ( n = 2)]. Five had Anti-Ro antibodies (three also ANA positive). Predominantly UVA and visible light photosensitivity was observed on phototesting.

Discussion:

PPIs are a reversible cause of photosensitivity and DILE. Time to onset from drug initiation to symptoms can be prolonged, so clinicians should have a high index of suspicion in those taking PPIs. Most are diagnosed through clinical assessment and lupus serology, with phototesting indicated if there is diagnostic uncertainty.

Background: When comparing functional outcomes of patients with unicompartmental knee arthroplasty (UKA) versus total knee arthroplasty (TKA), studies often report the UKA as the preferred procedure; however, recent improvements in the design of modern TKA implants have aimed at narrowing this gap. Purpose: We sought to compare the “feel” of modern TKA implants to that of UKA, using the Forgotten Joint Score (FJS), a validated patient-reported outcome measure. Methods: We performed a retrospective review of patients who underwent TKA and UKA at 2 institutions between 2014 and 2017. All UKA procedures were robotic arm-assisted with a single implant, “traditional TKAs” were performed using traditional posterior-stabilized implants, and “modern TKAs” were performed using posterior-stabilized implants with a modern design. Differences in FJS were assessed using 1-way analysis of variance and independent 2-sample t tests. Results: A total of 600 patients were included in our study, with 200 patients in each surgical subcategory. Mean age was 62.8 ± 10.2 years and mean body mass index was 29.9 ± 4.9. Modern TKA and UKA had similar FJS at 1 year. While modern TKA had a significantly higher FJS than traditional TKA, UKA did not have a significantly higher FJS than traditional TKA. Conclusion: Our retrospective analysis found no significant differences in the FJS of patients who underwent UKA and TKA with a modern design; however, both had superior scores than traditional TKA designs. This finding suggests that modern TKA designs may have the potential to achieve the natural feeling that is typically associated with joint-conserving surgeries such as UKA, although longer follow-up is necessary.

While vaccination against COVID-19 has significantly improved the morbidity and mortality of the disease, with the increase in the administration of COVID-19 vaccines, it is more likely to observe their rare side effects in the clinical settings. Herein, we report a case of an 82-year-old man with history of coronary artery disease, prostate cancer in remission, gastroesophageal reflux disease, and hypothyroidism, who presented with acute pancreatitis few hours after receiving the third dose of Pfizer-BioNTech BNT162b2 mRNA COVID-19 vaccine, without other identified etiology. His symptoms were mild and he was discharged in a stable condition after improvement in his condition with supportive care.

Study design

National cross-sectional study.

Objective

Thoracic kyphosis (TK) is related to sagittal parameters as pelvic tilt (PT), lumbar lordosis (LL) and pelvic incidence (PI). The equation TK = 2 (PT+LL–PI) was validated for adolescents. The purpose of this study was to investigate if this equation correctly predicts TK regardless of age.

Methods

Sagittal alignment parameters were assessed on full spine radiographs of 2599 individuals without spine pathology (1488 females, 1111 males). Calculated TK (CTK) = 2 (PT+LL–PI) and measured TK (MTK) were compared by calculating the gap and using a linear regression between both parameters. Subgroup analyses were performed for gender, age, TK groups (≤20°, 21°-40°, 41°-60°, >60°), and PI groups (<45°, 45°-60°, >60°).

Results

Average values in the total population were: MTK 45.0°, CTK 36.9°. Average TK gap was 8.1°, 5.2° in females (intercept 11.7, slope .61) and 11.9° in males (intercept 7.1, slope .58). The mean gap was 3.6° for 15-34 years, 5.7° under 15 years and it increased progressively after 35 years with a maximum of 19.9° over 80 years. The gap also increased with the amount of MTK: -3.5° for TK<20° up to 17.3° for TK >60°. Differences in gaps were minor between PI groups. The intercept was smallest and slopes >.6 for PI <45° and TK ≤20°.

Conclusion

The formula TK=2 (PT+LL-PI) yielded moderate accuracy for adolescents and young adults, but did not fit for over 35 years and under 15. The amount and variance in TK increased in elderly subjects, which made the formula less accurate.

Published: October 2022

Study design

Observational study.

Objectives

To evaluate the prevalence of erectile dysfunction and evaluate the effects of decompressive surgery on erectile dysfunction in cervical spinal stenosis and lumbar canal stenosis patients.

Methods

This observational, prospective analysis enrolled patients aged 18-80 with cervical spinal stenosis and/or lumbar canal stenosis that underwent respective decompressive surgery. The IIEF-5 questionnaire was administered preoperatively, and at 6- and 12-months postoperatively to assess erectile dysfunction severity. The EPIC database was queried to determine any postoperative complications and document prominent erectile dysfunction risk factors.

Results

Of 79 patients included in the analysis, 42 (53.2%) completed the IIEF-5 at 6 months, and 62 (78.5%) completed it at 12 months. Eighteen had cervical stenosis only, 54 had lumbar stenosis only, and 7 had both. 72% (18/25) of cervical stenosis patients and 83.6% (51/61) of lumbar stenosis patients had erectile dysfunction preoperatively according to IIEF-5 responses. The average preoperative IIEF-5 score indicated significant presence of erectile dysfunction for both the cervical and lumbar stenosis groups. No significant differences were identified in IIEF-5 score deltas from pre- to both postoperative periods. The presence of erectile dysfunction in both the cervical and lumbar stenosis groups was not significantly associated with the presence of any documented risk factors.

Conclusions

Our results suggest no significant improvement in overall erectile function postoperatively for patients with preoperative erectile dysfunction. This is important to address during patient counseling for decompression surgery candidates with cervical spinal stenosis and/or lumbar canal stenosis to manage expectations.
Application of supported Cu–Ru catalysts for the removal of trace olefins in aromatics
Authors: Liang Xiao , Liu Naiwang , Shi Li , Meng Xuan
Published: October 2022

Exploring reliable hydrogenation catalysts to remove trace olefins in aromatic hydrocarbons through hydrogenation is an important topic. In this paper, a bimetallic Cu–Ru/montmorillonite (Cu–Ru/M) catalyst was prepared using a step-by-step impregnation method, and the effects of bimetallic catalysts on removing olefins were assessed. The catalysts were characterized using X-ray diffraction, Brunauer–Emmett–Teller specific surface area, inductively coupled plasma atomic emission spectrometry, high-resolution transmission electron microscopy and temperature-programmed reduction of H2. The results show that there is a strong interaction between Cu and Ru on the Cu–Ru/M catalyst, which improves the dispersion of the metals on the surface of the support M. The hydrogen spillover phenomenon of Cu–Ru/M enhances its activity and adsorption capacity for hydrogen species. The catalytic performance test confirmed that the bimetallic catalyst has significantly greater activity and stability. The optimal loadings are 5% copper and 1% ruthenium, and the performance of this catalyst is comparable to those of noble-metal Pt/M catalysts.

Objective

To establish a prediction model for acute gastrointestinal injury (AGI) in patients with prolonged disorder of consciousness (pDOC) and to evaluate and apply the prediction model. 

Methods

The clinical data of 165 patients with pDOC admitted to the hyperbaric oxygen department from January 2021 to December 2021 were retrospectively reviewed, and the patients were divided into an AGI group (n = 91) and an N-AGI group (n = 74) according to whether AGI occurred. A prediction model was built by fitting multiple independent influencing factors through logistic regression. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of the model, the Hosmer–Lemeshow (H–L) test was used to evaluate the goodness-of-fit of the model, and the ROC curve and calibration curve were drawn to evaluate the predictive performance. A nomogram was plotted to visualize the prediction model.

Results

According to the multivariate logistic regression analysis results, the prediction model was finally constructed with the CRS-R score, DAO, PCT, ALB, and I-FABP, and a nomogram was generated. The area under the ROC curve (AUC) of the prediction model was 0.931, the sensitivity was 83.5%, and the specificity was 93.2%. The data were divided into 5 groups for the H–L test (χ2 = 2.54,P = 0.468 > 0.05) and into 10 groups for the H–L test (χ2 = 9.98,P = 0.267 > 0.05). A calibration curve was drawn based on the test results, indicating that the prediction model has a good goodness-of-fit and good prediction stability.

Conclusion

The prediction model for AGI in pDOC patients constructed in this study can be used in clinical practice and is helpful to predict the occurrence of AGI in pDOC patients.
