Preparing and sharing the table: The invisibility of women and enslaved domestic workers in Luke’s Last Supper
Authors: Cobb Christy
Published: December 2020

In biblical narratives that involve food, women and enslaved domestic workers were very involved in the planning, preparation, and the partaking of meals, even though they are mostly invisible in biblical texts. To make these women and enslaved workers visible, I closely examine the narrative of the Last Supper, or Passover, in the Gospel of Luke (22.7–38). In this gospel, women are present as followers of Jesus and are present with Jesus throughout his ministry, thus their presence at the Last Supper would be expected. In addition, enslaved characters fill the Gospel of Luke as a part of parables as well as within the narrative. In the conclusion of this article, I reimagine the scene of Luke’s Last Supper as it might have happened historically, with women and enslaved persons made visible in the preparations and during the meal itself.
Dinner in paradise: The fruit of the tree of life in the New Jerusalem
Authors: Gilchrest Eric J.
Published: December 2020

This article focuses on the final chapter of the Bible to tease out interpretative interests connected to the fruit of the tree of life that appears in Rev 22:1–3. It explores three specific themes to reinterpret them for our own culture: an abundance of food, the curse of work connected to Genesis 3, and a Christological interpretation of the entire paradise scene found in Revelation 22. Revelation 21–22 is a text about the renewed heaven and earth that speaks to deeper human needs plaguing all generations and contexts, not just the ancient context. The article, therefore, begins by examining various echoes that an ancient interpreter would have heard, setting the text within its ancient context. However, it does not leave the text there. After placing the tree of life in its ancient context, the article then reinterprets the fruit of the tree in a modern context.

Published: December 2020

Noise pollution is one of the harmful physical sources in the textile industry, which is among those industries that are faced with noise exposure problems. The results of environmental sound measurements at modern textile mills have shown that the sound pressure level varied from 95 to 130 dB, where the highest sound pressure level was at weaving machines. Textile insulation materials can be fitted in order to decrease sound pollution at a low cost. The objective of this work is to design a sound absorber that can be fixed to the body of the machines, at the point of the noise generation, to reduce noise pollution. Poly(lactic acid) (PLA), which is an environmentally friendly material, was used to produce different samples of meltblown nonwoven absorbers to be used for damping the noise of textile machinery. PLA meltblown nonwoven fabric with the areal density of 16.7 g/m2, average fiber diameter of 1.1 µm, mean pore diameter of 9.8 µm and thickness of 0.27 mm exhibited significant sound absorption. The sample with the smallest average fiber diameter among those investigated had the highest damping effect: 23.95, 41.29 and 29.32 dBA at frequencies of 400, 1000 and 1500 Hz, respectively. Our goal is to have a practical tool that accurately evaluates the absorber sound damping under the actual running conditions of the textile machinery. The design of the absorber from one layer of the PLA meltblown nonwoven over a rigid polyurethane foam sheet had an excellent sound absorption property.

Published: December 2020

Our cross-sectional study estimated the prevalence and clinical relevance of hypokalaemia among confirmed COVID-19 cases admitted in three hospitals in Bangkok during the early outbreak in Thailand. Of 36 patients, nine were in the hypokalaemia group (25%) and 27 in the normokalaemia group (75%). All cases were asymptomatic, and 94.4% had mild hypokalaemia. Hypokalaemia was found significantly earlier in the course of COVID-19 without evidence of significant extrarenal potassium loss. Body temperature and mean serum sodium in the hypokalaemia group tended to be higher than the normokalaemia group. Hypokalaemia and potentially higher serum sodium among COVID-19 patients were the remarkable findings. This issue warrants for further investigation.

A validation study the Iranian Modified Barthel Index (MBI) in hospitalized acute stroke elderly by classical test theory approach and investigate Rasch analysis for both Iranian version MBI and BI and compare the hierarchical item difficulty of them. Face-to-face interview with 100 geriatric stroke inpatients 60+ or their caregivers was done in a cross-sectional study. First, construct validity of MBI analyzed by the classical test theory, then Rasch analysis were done for BI and MBI. The reliability of the Iranian MBI was significant at 0.955. One factor achieved by the variance of 83.2%. In Rasch analysis for MBI, the most difficult item was stair climbing, whereas the simplest items were bowel and bladder control. In BI, the most difficult items were toilet use and ambulation. The Iranian MBI is very accurate and reliable; therefore the use of MBI to measure better outcomes in stroke elderly inpatients is recommended comparing with BI.
“I Could Do Stereotypical Old People Things … but I Feel Like I Would Get Bored With That Stuff”: College Students’ Proactive Steps to Avoid Negative Aspects of Aging
Authors: Hahn Sarah J. , Kinney Jennifer M.
Published: December 2020

The preventive and corrective proactivity model explores how internal and external resources mediate age-related stressors to counter negative outcomes of aging. Older adults’ proactivity about their future is consistently associated with higher quality of life, but research has not explored younger adults’ perceptions of their aging. We used interpretive phenomenology analysis to analyze 24 students’ essays from the beginning and end of an introductory gerontology course to understand anticipated adaptation to their 75-year-old self. The superordinate theme proactive steps to avoid negative aspects of aging comprised five subordinate themes (being productive, exercising and eating right, being financially stable, being socially connected, and the roles of older adults). Students presented unrealistically positive selves at 75 and discussed how to maintain and adapt to redefine their aging experience. Findings have implications for research on adaption, proactivity, and the future-self, and suggest that pedagogy incorporates realistic expectations of aging.
Bringing Meaning to Learning: An Interdisciplinary Project for First-Year Community College Students
Authors: Rima Brandi , Rodriguez Crystal C.
Published: December 2020

Interdisciplinary pedagogy can enhance Introduction to Psychology curricula. We developed an interdisciplinary project to make meaning in a learning community (LC) clustering Introduction to Psychology with Introduction to Criminal Justice. Our purpose is to describe the project as a model and report on students’ evaluations of the project and their academic progress. We collected questionnaire data about students’ experiences completing the project. Results were positive with most students valuing make meaning, feeling more connected to psychology and expressing satisfaction. We measured student learning using project grades and final grades in the psychology course. Participants performed satisfactory on the project and outperformed a comparison group in the Introduction to Psychology course. Findings demonstrate the value of interdisciplinary pedagogy in psychology curricula.
The Role of FDI on Exports Performance: Evidence from the Mexican States
Authors: Cabral René , Alvarado Jorge Alberto
Published: December 2020

This article examines manufacturing export determinants across Mexican states and regions from 2007 to 2015. Paying particular attention to the role of FDI, the analysis considers internal and external determinants of manufacturing exports under static and dynamic panel data methods. Several interesting results were obtained. First, the ratio of manufacturing to total GDP is the most consistent determinant of exports performance, regardless of the estimation method or specification employed. Second, static panel data estimations under GMM techniques suggest different sensitivity to FDI across regions, with the Mexico-U.S. border region observing the most substantial short-term effect of FDI on manufacturing exports. Finally, using dynamic panel data methods, we found significant persistence and similar long-term effects of FDI across most of the regions.
The problem of undersampling for models of archaeological occupations derived from shovel testing and its consequences for significance determinations
Authors: Alvey Jeffrey S
Published: December 2020

Archaeologists working in the Eastern United States routinely employ shovel testing as a method for site discovery and delineation in areas of dense ground cover, and as a means of collecting information on the kinds and numbers of artifacts and features present at a site. This sampling strategy is employed in the context of Section 106 compliance, as well as in academic research. This paper presents findings on the relationship between shovel-testing strategies and the accuracy and usefulness of the models of archaeological occupations that result from the information collected during shovel testing. These results demonstrate that some common approaches to shovel testing lead to faulty models that fail to accurately represent important occupational variables, thus compromising our ability to make valid significance determinations.
Little things mean a lot: Using the biopsychosocial model for daily reports of sexual intimacy
Authors: Leavitt Chelom E. , Siedel Amber J. , Yorgason Jeremy B. , Millett Mallory A. , Olsen Joe
Published: December 2020

Objectives:

In the current study we used an integrated approach to late midlife sexuality. Using a biopsychosocial approach combined with spillover/crossover theory, we examined various common biological (feeling rested and physical intimacy), psychological (positive and negative mood), and social (giving and receiving support) daily processes linked with actor and partner daily physical intimacy.

Methods:

Data from 191 late midlife, heterosexual, White, couples (97% married, 3% cohabiting) across 14 days were used to examine our hypotheses. Participants had attended some college and about half lived in an urban area.

Results:

Results from dyadic logistic multilevel models suggest that even when accounting for all covariates, physical activity, positive mood, and both giving and receiving partner support were associated with an increased likelihood of daily physical intimacy. Differences in these associations were found for women compared to men.

Discussion:

Physical intimacy in late midlife is likely encouraged from a number of factors. Using simplistic designs may inhibit our understanding of important sexual interactions. When compared to health factors, relational factors appear to be more connected to physical intimacy. Physicians, therapists, and community educators can encourage late midlife couples to pay attention to the support they give and receive which may provide an important environment for sexual interactions.
Successful second language pronunciation learning is linked to domain-general auditory processing rather than music aptitude
Authors: Zheng Chaoqun , Saito Kazuya , Tierney Adam
Published: December 2020

Whereas a growing amount of attention has been directed to the role of perceptual-cognitive aptitude in successful second language (L2) lexicogrammar learning, scholars have begun to investigate the same topic in the context of L2 pronunciation learning. To date, there is ongoing discussion on the mechanism underlying L2 speech learning in relation to music aptitude and domain-general auditory processing ability. Situated within 48 moderately experienced Chinese learners of English in the UK (length of residence = one year), the current study examined the relationship between music aptitude, auditory perception, and L2 pronunciation proficiency. Results revealed that music aptitude and auditory processing were partially overlapping, whereas both abilities were independent of participants’ past and current L2 language learning experience. Whereas individual differences in auditory processing demonstrated significant associations with various dimensions of L2 pronunciation proficiency, music aptitude was only weakly predictive of prosodic aspects of L2 pronunciation proficiency. Comparatively, none of the experience variables were related to acquisition within the current dataset.
TETFund intervention in the provision of library resources in academic libraries in Nigeria
Authors: Onyeneke Cajetan , Ahaneku Ihunanya Lovelyn
Published: December 2020

This study investigated the intervention of TETFund in the provision of library resources in academic libraries in Imo State, Nigeria. It was guided by four research questions and three null hypotheses. The study adopted a survey research design with a questionnaire as the research instrument. The population of the study was 105 professional and para-professional library staff at two universities in Imo State. The findings show that TETFund intervenes to a high extent in the provision of information resources at the two universities studied. The study recommends that concerned government ministries should monitor the activities of TETFund to ensure that universities benefit equally, and that TETFund should be mandated to make the processes simpler. The researchers also recommend that TETFund organize conferences to educate institutions on the need and processes to access funding and benefit from TETFund.
Seeking the ‘Truth’ from ‘Enumerating’ Numbers: Leprosy in Census and Public Health Reports of Colonial Bengal: 1890s–1940s
Authors: Das Apalak
Published: December 2020

Figures are required to execute the policies in a way in which the state prepares the statistics of ‘progresses’. This is a form of ‘truth’ that is unquestionable and absolute to the administration. But often, the numbers are constructed, exaggerated and even invented, hiding the grim reality for the sake of upholding the achievements of a welfare state. Census has been one of the ‘scientific tools’ since the nineteenth century, by which the state retains its supervision over the population and preserves the information for future reference. Such process of institutionalising ‘truism’ would be considered as an ultimate solution of the problems that the enumerators encounter with the ‘infirm’. This article seeks to explore how far the enumerations had paved the way for resolving the issues regarding the ‘lepers’ and ‘deformity’ in colonial Bengal since 1891 when the decennial census was taken immediately after the death of Father Damien. The article also intends to problematise the notion on ‘diseased bodies’, that is, ‘lepers’ that the Raj tried to marginalise through census figures to protect the healthy populace from probable degeneration. Thus, it studies the leprosy and ‘lepers’ both by analysing the census and public health reports within the context of Empire and colonial Bengal.

Paul Moore's Centennial Land Run Monument
Authors: Alt Gordon
Published: December 2020

In 2019, Sculptor Paul Moore FNSS completed his monument of the 1889 Centennial Land Run in Oklahoma City, OK. It took him over twenty years to complete this powerful work, which is one of the largest monuments in the world. It stretches over an area slightly larger than a football field and contains forty‐five powerful sculptures of horsemen and wagons racing over the Oklahoma landscape of hills and creek. It is a vision that caught the moment after a cannon announced the beginning of the Land Run, in which over 50,000 individuals took part in an effort to claim land in the Oklahoma Territory. The sculpture contains masterful images of straining horses and frantic individuals caught in a vital effort to succeed in this race to claim valuable homesteads and pastureland. Moore was awarded the Medal of Honor by the National Sculpture Society this past October, partially in regard for this outstanding public work and the quality of sculpture this extraordinarily talented artist has created in his lifetime.
Research on the optimal design technology of a digital assembly sequence based on an internet of things data collection framework
Authors: Cao Yan , Huang Liang , Li Zhuanxia
Published: December 2020

The assembly of a machine tool modular fixture with a complex structure, flexible layout and poor regularity characteristics is used as an example in this paper to establish an IOMT system for optimizing the assembly sequence of a machine tool modular fixture based on IOT technology driven by modern intelligent identification and acquisition technology, with the aim of addressing the shortcomings of existing assembly technology in the traditional serial design method. From the perspective of an inverse sequence of an assembly sequence, and combined with the disassembly sequence data extracted by the perceptual assembly layer control unit under the environment of the IOT, the disassembly sequence data can be mathematically expressed by using three mainstream heuristic algorithms (i.e. the artificial fish swarm algorithm, the genetic algorithm, and the ant colony algorithm), while considering the disassembly quality, disassembly cycle and cost. Then, the three algorithm models are used to analyse the example of a machine tool modular fixture, and the calculation efficiency and solution accuracy are comprehensively evaluated; Simulation results show that the ant colony algorithm has the highest computational efficiency and the highest accuracy in a complex data environment. Therefore, the construction of an IOMT system for optimizing the assembly sequence of a machine tool modular fixture can be realized by using the ant colony algorithm.

HIV-related enacted stigma and social problems may increase risk for depression and/or behavioral problems among adolescents and young adults with perinatal HIV(AYA-PHIV), yet few studies have explored stigma in AYA-PHIV residing in low-to-middle income regions, including Southeast Asia. We assessed HIV-related enacted stigma and social problems in AYA-PHIV who participated in the RESILIENCE study (clinicaltrials.gov identification: U19AI53741) in Thailand and Cambodia using specific questions during structured in-person interviews. Depression was measured by the Child Depression Inventory for children <15 years, or the Center for Epidemiologic Studies Depression Scales for youth ≥15 years); behavioral problems were measured by the Child Behavior Checklist (CBCL-caregiver report). Among 195 AYA-PHIV (median age 16.9 years), 25.6% reported a lifetime experience of enacted stigma, while 10.8% experienced social problems due to HIV infection. The frequency of depressive symptoms was nearly two-fold higher among AYA-PHIV with compared to those without HIV-related enacted stigma (34.7% vs. 16.0%, p = 0.005). Caregiver-reported behavioral problems were detected in 14.6% of all AYA-PHIV, with no differences between those with and without HIV-related enacted stigma. Low household income and caregiver mental health problems were independent risk factors for depressive symptoms; HIV-related enacted stigma was also associated with increased risk, warranting targeted services to support AYA-PHIV.
Benefits of digital breast tomosynthesis: A lesion-level analysis
Authors: Amir Tali , Ambinder Emily B , Harvey Susan C , Oluyemi Eniola T , Jones Mary K , Honig Evan , Alvin Matthew D , Mullen Lisa A
Published: December 2020

Objective

To compare outcome metrics of digital breast tomosynthesis (DBT) breast cancer screening with full-field digital mammogram (FFDM); specifically, to compare recall rates by the type of recalled finding, and to assess if screening with DBT versus FFDM changes biopsy recommendations and if the likelihood of malignancy varied by lesion type, if detected on DBT or FFDM screening mammogram.

Methods

The outcomes of 22,055 FFDM and DBT screening mammograms were retrospectively reviewed. The exams were performed at an academic institution between August 2015 and September 2016. Performance of screening with FFDM versus DBT was compared in terms of recall rate and percentage of recalled lesions resulting in a cancer diagnosis, with subset analyses performed for specific mammographic findings.

Results

The recall rate was 10.6% for FFDM and 8.0% for DBT ( p < 0.001). Architectural distortion was more likely to be recalled on DBT screening than FFDM ( p = 0.002), and was associated with an increased likelihood of malignancy ( p = 0.008). Asymmetries were less likely to be recalled on DBT than FFDM ( p < 0.001) screening mammogram, but more likely to be recommended for biopsy when detected on DBT. Calcifications more frequently required short-term follow-up or biopsy on both DBT and FFDM.

Conclusions

DBT screening confers an advantage in detection of architectural distortion representing malignancy. Recall rate of asymmetries are reduced with screening DBT, probably due to reduction of tissue superimposition. Calcifications pose a particularly difficult diagnostic challenge for breast imagers, regardless of screening mammogram type.
Artificial intelligence and human rights: Between law and ethics
Authors: Sartor Giovanni
Published: December 2020

The ethics and law of AI address the same domain, namely, the present and future impacts of AI on individuals, society, and the environment. Both are meant to provide normative guidance, proposing rules and values on which basis to govern human action and determine the constrains, structures and functions of AI-enabled socio-technical systems. This article examines the way in which AI is addressed by ethical and legal rules, principles and arguments. It considers the extent to which the demands of law and ethics may pull in different directions or rather overlap, and examines how they can be coordinated, while remaining in a productive dialectical tension. In particular, it argues that human/fundamental rights and social values are central to both ethics and law. Even though they can be framed in different ways, they can provide a useful normative reference for linking ethics and law in addressing the normative issues arising in connection with AI.
Influences of Family Relational Factors and Immigration Generation Status on Mental Health Service Utilization Among Asian Americans
Authors: Wang Xiaochuan
Published: December 2020

Drawing on data from the National Latino and Asian American Study, this article examines the influence of family relational factors, independently and jointly with immigration generation status, on past-year mental health service utilization among Asian Americans ( N = 1,599). Findings revealed the important role of family relation in influencing the likelihood and type of Asian Americans’ mental health service use. Lower level of family cohesion and higher level of family conflict were associated with increased likelihood of service use. Results from multiple logistic regressions further indicated that generation status interacts with family relation in affecting service use. Specifically, effect of family cohesion on general health service use was modified by generation status among third- or later-generation Asian Americans. Practice implications and future research directions are discussed to better understand and address the mental health needs of this population.
Dynamics of symmetric and asymmetric potential well-based piezoelectric harvesters: A comprehensive review
Authors: Giri Abhijeet Madhukar , Ali Shaikh Faruque , Arockiarajan Arunachalakasi
Published: December 2020

Small and micro-scale energy harvesting is an essential and viable option for the powering of portable and maintenance free electronic devices, wireless sensor nodes, and similar applications. In this regard, piezoelectric harvesters have presented promising outcomes. This article provides a sequential, comprehensive, and informative survey of potential well based models and studies related to piezoelectric harvesters (PEH). Piezoelectric materials used for energy harvesting are discussed briefly, following which a non-dimensional generalized model is derived to set the discussion on a common platform. Dynamics of various potential well configurations are presented using the generalized model before discussing specific models and related studies. The survey is classified into symmetric and asymmetric potential well categories. Under the symmetric head, lumped and distributed parameter linear models and tuning methods for improving the broadband response are discussed. Subsequently, studies related to nonlinear mono-stable, bi-stable, and tri-stable potentials showing interwell, multi-periodic and chaotic oscillations with improved broadband response are discussed. The asymmetric section studies the influence of asymmetries on the performance of the mono-stable, bi-stable, and tri-stable configurations. Few other configurations outside the cantilever type PEH were mentioned, realizing the widespread research in this field. Important observations and future challenges for performance improvement are also discussed.
Adaptive active vibration control for piezoelectric smart structure with online hysteresis identification and compensation
Authors: Pu Yuxue , Yao Cheng , Li Xiaobao , Liu Zhaotao
Published: December 2020

Smart structure vibration reduction based on adaptive active vibration control has become a hot research spot in recent years. A filtered-U least mean square algorithm based on an infinite impulse response filter structure is used to solve the interference of controller output to reference signal. The filtered-U least mean square algorithm is very suitable for the nonlinear vibration control of the flexible structure. This study focuses on the analysis and implementation of an adaptive active vibration control system for smart structure with a surface-bonded piezoelectric actuator. The piezoelectric actuator contained in the secondary path has nonlinear hysteresis property. The nonlinear hysteresis property will cause a nonlinear relationship between the structural vibration response and the control voltage, which deteriorates the robustness and control effect of the adaptive control. This study designs an improved version of the filtered-U least mean square algorithm with online hysteresis identification and compensation (filtered-U least mean square–online hysteresis identification and compensation) based on a discrete Prandtl–Ishlinskii model. The Prandtl–Ishlinskii model parameters of the nonlinear hysteresis property are identified online based on the least mean square algorithm. Based on the identified Prandtl–Ishlinskii model parameters, an inverse hysteresis compensator is established for feedforward compensation in the secondary path. Simulation results show that the proposed method can dynamically compensate the hysteresis nonlinearity of the secondary path, linearizing the nonlinear hysteresis. The vibration reduction effect of the proposed method is obviously better than that of other competing methods. A piezoelectric smart cantilever plate with PZT (or lead zirconate titanate, Pb (Zr, Ti)) actuators and sensors is designed to demonstrate the validity and efficiency of the proposed method by experiments. Experiment results demonstrate that the adverse effect of nonlinear hysteresis is eliminated well after feedforward hysteresis compensation is introduced; the unexpected frequency vibration caused by the hysteresis property is suppressed. The proposed methodology possesses an important advantage in application of the adaptive active vibration control of the piezoelectric smart structure.
Three-dimensional pulse response of curved composite sandwich panel with compressible core using non-linear higher-order theory
Authors: Ahmadi Seyed Ali , Pashaei Mohammad Hadi , Jafari-Talookolaei Ramazan-Ali
Published: December 2020

In this paper, the dynamic response of cylindrical sandwich panels with compressible core is obtained using the extended non-linear higher-order sandwich panel theory. It is assumed that the sandwich panel has simply supported boundary at all edges and is consisted of orthotropic face sheets and viscoelastic core layer. To describe the mechanical properties of the viscoelastic foam core, the Kelvin-Voigt linear viscoelastic model was applied. Three-dimensional linear equations of motions were used to describe the sandwich panel deformations. The effects of various parameters including the panel span, core and facing thickness, the viscous damping factor, pulse duration, and maximum pressure on the dynamic response of the sandwich cylindrical panel are studied. The results obtained from present method are compared with finite element solutions and those reported in the literature, and consequently, agreement among the results could be observed. The results shown that applied viscoelastic model has a signification effect on the panel response and reduces the magnitude of vibrations. The presented programming code (DQ) needs less computational time and computer hardware capacity and is faster than finite element solution.
The incidence and risk factors of neovascular glaucoma secondary to proliferative diabetic retinopathy after vitrectomy
Authors: Sun Difang , Lin Yifan , Zeng Rui , Yang Zhenlan , Deng Xiaowen , Lan Yuqing
Published: December 2020

Objective:

The incidence and risk factors of neovascular glaucoma (NVG) secondary proliferative diabetic retinopathy (PDR) after pars plana vitrectomy (PPV) are unclear and reports in the published literature are inconsistent. Therefore, a systematic review and meta-analysis were conducted to clarify the risk factors associated with neovascular glaucoma.

Methods:

PubMed, Embase, and The Cochrane Library were systematically searched without language limitations for studies related to NVG after PPV in PDR patients. We used R software to fit the correlation between incidence and the date of publication for studies and performed a Spearman analysis. For binary and continuous variables, the odds ratios (ORs) with 95% confidence intervals (CIs) were pooled, respectively, using Review Manager 5.3 (The Cochrane Collaboration).

Results:

Twenty-six studies with 5161 patients were included in our meta-analysis. The overall pooled incidence of NVG after PPV in PDR patients was 6% (95% CI, 0.05–0.07, p-value < 0.00001). Pooled estimates indicated a positive correlation for NVG after PPV in PDR patients with higher baseline IOP (OR, 1.26; 95%CI,0.56–1.95, p-value = 0.0004), preoperative iris neovascularization (INV) (OR, 5.66; 95% CI, 2.10–15.23, p-value = 0.0006), preoperative or intraoperative combined cataract surgery (OR, 2.00; 95% CI, 1.15–3.46, p-value = 0.01), postoperative vitreous hemorrhage (VH) (OR, 3.53; 95% CI, 1.63–7.66, p-value = 0.001), and a negative correlation with age (OR, −2.90; 95%CI, −5.00 to −0.81, p-value < 0.007).

Conclusion:

Our systematic review and meta-analysis indicated that the main risk factors for NVG after PPV in PDR patients included higher baseline IOP, preoperative INV, preoperative or intraoperative combined cataract surgery, postoperative VH, and was negatively correlated with age.
Analysis of bleb morphology after CLASS with ultrasound biomicroscopy and clinical grading scale
Authors: Yan Xiaowei , Zhang Hengli , Tang Guangxian , Li Fan , Ma Lihua , Geng Yulei
Published: December 2020

Objective:

Filtration in the area subjected to CO2 laser-assisted sclerectomy surgery (CLASS) is described using ultrasound biomicroscopy (UBM) and the clinical grading scale to evaluate the mechanism of intraocular pressure (IOP) reduction.

Methods:

Twenty-eight patients with open-angle glaucoma underwent CLASS. The Indiana Bleb Appearance Grading Scale evaluation was performed 1 month after surgery to determine bleb height, extent, vascularity, and leakage. UBM was used to describe and measure the surgical area. Bleb morphology, the size of the scleral lake, scleral route, and trabeculodescemetic membrane (TDM) thickness were examined.

Results:

One month after CLASS, IOP significantly decreased from 20.46 ± 3.92 mmHg to 12.71 ± 2.99 mmHg, and the anterior chamber depth significantly more shallow, from 2.75 ± 0.36 mm to 2.61 ± 0.33 mm( p < 0.05). Shallow uplift occurred in 71.43% of the blebs, and 64.29% of the blebs were within 1 to 2 h; 82.15% showed mild or moderate vascular hyperemia, and the Seidel test was negative. UBM showed that all eyes had an intact TDM, with a mean thickness of 99.3 ± 22.2 μm; 21 eyes (75%) had L-type (low reflective). The scleral lake anteroposterior length, height, and transversal length were 2.247 ± 1.831 mm, 0.520 ± 0.234 mm, and 3.312 ± 0.423 mm, respectively. The TDM thickness and postoperative IOP were positively correlated, and the size of the scleral lake was not correlated with IOP reduction. Four eyes (14.29%) exhibited cyclodialysis.

Conclusion:

UBM examination indicated the aqueous humor drainage route. In the early stage after CLASS, subconjunctival and choroidal drainage routes might be the major mechanism underlying IOP reduction. Mild and moderate congestion of bleb blood vessels warrant attention to avoid early bleb scarring.
The effect of prenatal and early-postnatal exposure to classical air pollution on childhood pneumonia in China
Authors: Liu Yanlin , Lu Chan , Deng Miaomiao , Norbäck Dan , Sun Shujie
Published: December 2020

To investigate the role of different pattern of ambient air pollutants exposure during early life on childhood pneumonia, we conducted a retrospective cohort study of 3226 preschool children aged three to six years in Shenzhen, China during 2015 to 2016. Each child's exposure to three main air pollutants (PM10, SO2 and NO2) was calculated by the inverse distance weighted method. Multiple logistic regression analysis was used to investigate the pneumonia risk of early life exposure to air pollution. A relatively high prevalence of pneumonia (24.3%) among preschool children in Shenzhen was significantly associated with exposure to PM10 and SO2 during the first year of life, with adjusted odds ratios = 1.24 (1.05, 1.46) and 1.20 (1.05, 1.38) respectively. However, we observed no relationship between NO2 exposure and childhood pneumonia in pregnancy and first year of life. Sensitivity analysis suggested that boys, younger children (three to four years), non-preterm children, children without parental atopy and with exposure to environmental tobacco smoke were more susceptible to the impact of exposure to PM10 and SO2 on their suffering of pneumonia during their first year of life. Early-postnatal exposure to classical air pollution at low concentration during the first year of life can have an important role in enhancing the risk of childhood pneumonia, especially with the sensitive population.

In this paper, the failure behavior of fiber–metal laminate patches as a repair system for steel transmission lines has been investigated and the results are compared with those of the other materials commonly used for repairing pipelines such as composite patches. The laboratory test is also employed to experimentally estimate the pipe burst pressure for the tubes made of API A106 Grade B steel. A comparison of the results using different fiber–metal laminates patches and composite is made. As fillers, putties with two different elastic constants are introduced. Also, taking the cohesive behavior of the patch into account in the numerical model, the effect of the patch on the failure pressures is evaluated. The failure parameter in different patch layers for various types of fiber–metal laminates made of GLARE and CARRALL has been investigated. For significant improvement in the failure behavior of fiber–metal laminate patches, carbon fiber layers are used. Also, to prevent corrosion effects between aluminum and carbon fibers, a combination of aluminum, glass fiber reinforced polymer, and carbon fiber reinforced polymer is utilized. Moreover, the damage behavior of steel pipe and aluminum layers in the fiber–metal laminate patch has been numerically described. The results obtained in the present work clearly show the superior advantage of fiber–metal laminate patches over the conventional composite ones. Experimental results lead to the fact that internal pressure corresponding to final layer failure in composite patches and first layer failure in fiber–metal laminate patches should be considered as a reliable estimation to predict the final burst pressure.

This study applies a social identity and social network theory perspective to develop an integrated view of how hospitality firms incorporate family dynamics and tourism specifics as antecedents for good governance in the competitive hospitality industry. Seventeen qualitative semi-structured expert interviews with family hotel owner-managers in the province of Salzburg, Austria are systematically analyzed. The findings highlight the firms’ commitment to their destination as well as regional and social interactions originating both in the family dynamics of the firms and their strong embeddedness within their destinations as central factors for good governance. The results emphasize the need for entrepreneurial behavior and the involvement of family and non-family members in achieving effective governance structures.

Objective:

To clarify the clinical significance of breast cancer anti-estrogen resistance protein 1 (BCAR1) expression in circulating tumor cells (CTCs) in the peripheral blood and tumor tissues in patients with early stage lung adenocarcinoma (ES-LUAD).

Methods:

The study cohort included 60 patients with stage I LUAD (50 IA and 10 IB) who underwent surgery from November 2015 to November 2018 and 31 healthy controls. The expression levels of BCAR1 and markers of epithelial-mesenchymal transition (EMT) in peripheral blood CTCs were detected using CanPatrolTM technology before surgery, and immunohistochemical analysis was used to detect BCAR1 expression in tumor tissues collected from 40 patients. The predictive power of BCAR1 expression in CTCs and tumor tissues on disease-free survival (DFS) was analyzed. The Cancer Genome Atlas (TCGA) database was used to study BCAR1 expression and overall survival as validation. The Gene Expression Profiling Interactive Analysis online tool was used to analyze the correlations between the expression levels of BCAR1 and EMT molecular markers.

Results:

Both the number and detection rates of BCAR1-negative CTCs and BCAR1-positive CTCs in peripheral blood of lung cancer patients were significantly higher as compared with healthy controls ( p < 0.05). BCAR1-positive CTCs more commonly co-expressed both epithelial and mesenchymal markers. Kaplan–Meier analysis demonstrated that patients with BCAR1(++) CTCs in peripheral blood before surgery were more prone to recurrence or metastasis after 2 years. COX analysis showed that patients with higher abundance of BCAR1(++) CTCs had a poorer prognosis (hazard ratio [HR] = 1.712, 95% confidence interval [CI] = 1.077–2.272, p = 0.023). Furthermore, high BCAR1 expression in tumor tissues was predictive of a poor prognosis (HR = 2.654, 95% CI = 1.239–5.686, p = 0.012), as validated by TCGA database (HR = 2.217, 95% CI = 1.069–4.595, p = 0.032). In addition, BCAR1 expression in LUAD tissues from TCGA was significantly positively correlated with the expression of both epithelial markers (e.g., ck8/18/19) and mesenchymal markers (e.g., vimentin and twist).

Conclusion:

BCAR1 may have a “dual impact” on EMT markers in tumor tissues and CTCs due to micro-environmental disparities, resulting in important clinical significance, which can potentially guide accurate treatment of LUAD.
Promouvoir la santé de la population pendant la crise de la COVID-19 : le rôle des communes sur le canton de Vaud, en Suisse
Authors: Amstutz Delphine , Villa Oriana
Published: December 2020

La crise de la COVID-19 a mis en évidence les vulnérabilités et inégalités sociales de santé préexistantes. Elle a également montré le rôle des collectivités territoriales dans l’implémentation des recommandations de santé publique, qu’il s’agisse de prévenir la propagation du virus ou de promouvoir la santé de chacune et chacun. En Suisse, dans le canton de Vaud, les communes ont réagi promptement mais différemment selon les ressources et l’expertise à disposition. Bien que toutes ces actions soient louables, avec une réponse asymétrique, le risque de créer, voire de renforcer des inégalités territoriales de santé est néanmoins bien présent. Pour promouvoir la santé de manière équitable, efficiente et durable, nous devons renforcer les stratégies de promotion de la santé, assurer une meilleure coordination au niveau local, et développer une approche multisectorielle de la santé. Créer un groupe de coordination et d’accompagnement des communes en matière de promotion de la santé est une approche prometteuse.

Background

Few data exist concerning conversion to secondary progressive MS in patients treated with disease-modifying therapies.

Objective

Determine the proportion of alemtuzumab-treated patients converting from relapsing-remitting to secondary progressive MS during the CARE-MS core and extension studies.

Methods

Patients ( N = 811) were analyzed post hoc for secondary progressive MS conversion. Optimal conversion definition: Expanded Disability Status Scale (EDSS) score ≥4, pyramidal functional system score ≥2, and confirmed progression over ≥3 months including confirmation within the functional system leading to progression, independent of relapse.

Results

Over 6.2 years median follow-up, 20 alemtuzumab-treated patients converted (Kaplan-Meier estimate, 2.7%; 95% confidence interval, 1.8%–4.2%). Sensitivity analysis accounting for dropouts showed similar results (3%), as did analyses using alternative definitions with different EDSS thresholds and/or confirmation periods, and analysis of core study subcutaneous interferon beta-1a-treated patients who received alemtuzumab in the extension. Patients converting to secondary progressive MS were older, and had higher EDSS scores and greater brain lesion volumes at baseline, but did not need additional alemtuzumab or other therapies.

Conclusions

The 6-year conversion rate to secondary progressive MS was low for alemtuzumab-treated patients, supporting further study of the role alemtuzumab may play in reducing risk of secondary progression. ClinicalTrials.gov identifiers: NCT00530348, NCT00548405, NCT00930553.
Evaluating the impact mechanism of citizen participation on citizen satisfaction in a smart city
Authors: Xu Hualin , Zhu Wenlong
Published: December 2020

Citizen satisfaction is an important issue for global city managers in the construction of a smart city. To date, little research has been done on the effect of citizen participation on citizen satisfaction in a smart city. From the perspective of citizen involvement and based on the theory of involvement and American Customer Satisfaction Index model, this study explores the impact mechanism of citizen participation on citizen satisfaction in a smart city and constructs a theoretical model of citizen satisfaction. The data were collected in Qingdao, which is a smart city in China. The analysis shows that citizen involvement has a significant positive influence on citizen participation both cognitively and affectively. Furthermore, citizen participation produces a direct and significant positive impact on citizen satisfaction. Last, citizen participation can also have a significant positive influence on citizen satisfaction through perceived quality and perceived value. The main contribution of this study focuses on the construction of the impact mechanism model. Based on this model, researchers and city managers can understand the entire reaction process of the citizen ranging from subjective judgement to practical actions and then actual experiences in the construction of a smart city.
