Predictors of Antenatal Depression in Pregnant Couples
Authors: Oh Jiwon , Ahn Sukhee
Published: December 2021

Pregnant women and their partners are at an increased risk of antenatal depression. Therefore, this cross-sectional study of data from 116 couples investigated predictors of maternal and paternal antenatal depression using sociodemographic data, women’s risk factors for depression during the antenatal period, women’s perceived stress, and antenatal depression in the other partner. Pregnant women had higher depression scores (7.4 ± 4.7) and a higher frequency of being at high risk for depression (25.9%) than their spouses (4.6 ± 3.5, 9.5%). Multiple linear regression analysis revealed that the statistically significant predictors of antenatal depression in pregnant women were perceived stress (β = .45, p < .001) and antenatal depression risk factors (β = .30, p = .002) and in spouses, women’s antenatal depression risk factors (β = .29, p = .013). The present findings suggest that nurses should intervene to mitigate the risk of maternal antenatal depression and perceived stress to prevent depression in pregnant couples.

Published: December 2021

The aim of this study was to determine the psychometric properties of the Persian version of pregnancy symptoms inventory. A methodological study. This study was conducted on 220 pregnant women. Construct validity was measured by exploratory factor analysis and confirmatory factor analysis. Reliability was measured by intra-class correlation coefficient and internal consistency. Since the items 12 (snoring) and 16 (thrush) failed to obtain the minimum principal axis factoring in exploratory factor analysis, they were removed from the Persian version. Confirmatory factor analysis showed a good fit for the extracted model. Cronbach’s alpha was .94 for the frequency items and .95 for the limitation items. Intra-class correlation coefficient was between .58 and 1 for frequency items and between .73 and 1 for limitation items. The Persian version of pregnancy symptoms inventory was a valid and reliable scale to be used for Iranian pregnant women.

Published: December 2021

Menstrual hygiene management (MHM) among female students is a neglected public health issue in the U.S. This study documented period product insecurity, school absenteeism, and use of school resources to obtain period products among high-school students in St. Louis, MO. Female students completed an anonymous, self-administered survey in English (n = 119). Descriptive statistics were used to determine the prevalence of period product need, resources used to obtain period products, and period-related absenteeism. The mean age of participants was 15.78 ± 1.28. Nearly two-thirds (64.4% (95% CI 55.1%-73.0%)) reported period product insecurity. Two-thirds (66.9% (95% CI 57.7%-75.3%)) reported using at least one of the school's resources to obtain period products. One-third of the participants (33.6% (95% CI 25.0%-43.1%)) reported missing school due to a lack of period products. School nurses need to be cognizant of how MHM affects their students’ attendance at school and what measures they can take to help reduce menstruation-related absenteeism.

Authors: Balesar Vinay V. , Koster Lennard A. , Kaptein Bart L. , Keizer Stefan B.
Published: December 2021

Background:

Mixed results for functional outcomes and long-term fixation have been reported for first metatarsophalangeal arthroplasty. This prospective study was designed to evaluate the migration of the BioPro metatarsophalangeal-1 (MTP-1) joint hemiprosthesis with Roentgen stereophotogrammetric analysis (RSA). Migration patterns of the prosthesis, prosthesis-induced erosion of the metatarsal bone, and clinical outcomes were evaluated sequentially to 5 years postoperation (PO).

Methods:

Eleven female patients received the BioPro-1 hemiprosthesis. Prosthesis translation and metatarsal erosion were measured with RSA at immediately PO, 6 weeks, and 3, 6, 12, 36, and 60 months postoperatively. Clinical assessment was done by patient questionnaires.

Results:

RSA data of 9 patients were available for analysis. Median (range) number of markers used in RSA analysis, condition number, and mean error of markers around the prosthesis were 4 (3-7), 320 (208-862), and 0.13 (0.02-0.28), respectively. Progressive subsidence was seen up to 3 years PO (mean 2.1 mm, SE 0.32). Progressive metatarsal erosion was found from 1 year PO (mean 0.49 mm, SE 0.15). Pain, function, and quality scores improved after surgery and did not deteriorate at later follow-up moments.

Conclusion:

Model-based RSA of the BioPro-1 prosthesis shows nonstabilizing medial and distal translation and metatarsal erosion. Despite the measured migration and erosion, clinical outcomes improved and remained similar up to 5 years postoperation.

Level of Evidence:

Level II, prospective analysis of MTP-1 hemiprosthesis.
A block bayesian compressive sensing method based on the equivalent source method for near-field acoustic holography
Authors: Zan Ming , Xu Zhongming , Huang Linsen , Tang Zhonghua , Zhang Zhifei , He Yansong
Published: December 2021

The conventional equivalent source method for near-field acoustic holography is an effective noise diagnosis method using microphone array. However, its performance is limited by microphone spacing, so the effect is unsatisfied when the wave number is high. In this paper, to broaden the frequency suitability and improve the performance of sound source reconstruction with low signal-to-noise ratios, a block Bayesian compressive sensing method based on the equivalent source method is proposed. Numerical results show that this proposed method has a good reconstruction performance and makes wideband reconstruction possible. By changing the frequency, location, and signal-to-noise ratio of the sound source, the reconstruction performance of the proposed method can remain stable. Finally, the validity and practicability of the proposed method are verified by experiments.
On tangent geometry and generalised continuum with defects
Authors: Nguyen Van Hoi , Casale Guy , Le Marrec Loïc
Published: December 2021

This paper introduces tools on fibre geometry towards the framework of mechanics of microstructured continuum. The material is modelled by an appropriate bundle for which the associated connection and metric are induced from the Euclidean space by a smooth transformation represented by a fibre morphism from the bundle to Euclidean space. Furthermore, the general kinematic structure of the theory includes macroscopic and microscopic fields in a multiscaled approach, including large transformation. Defects appear in this geometrical point of view by an induced curvature, torsion and non-metricity tensor in the induced geometry. Special attention is given to transport along a finite path in order to extend the standard infinitesimal analysis of torsion and curvature to a macroscopical point of view. Both theoretical and numerical analysis may be handled without additional difficulties. Accordingly, several examples of transformation involving the distribution of material defects are exhibited and analysed.
Finite deformations of fibre-reinforced elastic solids with fibre bending stiffness – Part II: determination of the spherical part of the couple-stress
Authors: Soldatos KP
Published: December 2021

The indeterminacy of the spherical part of couple-stress is a well-known drawback of any theoretical formulation stemming from the Cosserat couple-stress theory of elasticity. The relevant theory of finite elastic deformations of solids reinforced by a family of fibres that resist bending is not an exception. The present communication extends and completes that theory in a manner that enables it to measure the spherical part of the couple-stress tensor outside the conventional equilibrium considerations. To achieve this, the present study reconsiders an extra piece of information that has surprisingly emerged already but, so far, has been left unexplained and unexploited; namely, the fact that the energy stored in a fibrous composite elastic solid with fibre-bending stiffness involves a couple-stress generated term that does not influence the relevant couple-stress constitutive equation. The thus resulting new theoretical development complements the theory previously presented without dismissing any of the theoretical results detailed or the conclusions drawn there. Its validity embraces boundary value problems concerning both finite and infinitesimal elastic deformations of polar fibrous composites. In the latter case, its applicability is also tested and verified through the successful determination of the spherical couple-stress of a polar transversely isotropic elastic plate subjected to pure bending.
Placental Heterogeneity in Stillbirth and Its Relations to Maternal Exogenous Characteristics

Published: December 2021

Introduction: Heterogeneous patterns of placental lesions in stillbirth signal important variations in placental histopathology that may be diagnostic in stillbirth. We explore placental heterogeneity and its associations with maternal characteristics (including HIV) using latent class analysis.

Methods: Placental and maternal data and slides were assessed retrospectively for 122 confirmed stillbirths (gestational age ≥ 28 weeks) delivered at a major South African academic hospital between January 2016–July 2018. The slides were reviewed by 2 pathologists and classified using the Amsterdam Consensus Classification System. Latent class analyses were conducted on raw data.

Results: We identify 5 latent placental classes in stillbirth based on similarity in patterns of observed diagnostic criteria and their associations with maternal characteristics. Three classes bear similarity to generalized patterns of placental injury identified previously. Our study shows that intrauterine infection was the commonest histopathological condition associated with stillbirth in our setting. Novel findings include 2 classes, distinguished by high placental RPH and maternal HIV, respectively, and the non-emergence of a class distinguished by VUE.

Conclusion: The size and content of the latent classes and their similarity/dissimilarity to the more generalized patterns identified previously suggest potential new avenues for investigation and theory development concerning the role of the placenta in stillbirth and the impact of HIV.
The Effects of Unfulfilled Preferential Treatment and Review Dispersion on Airbnb Guests’ Attitudes and Behavior
Authors: Zheng Xiaoyun , Zhang Lu , Line Nathan , Wei Wei
Published: December 2021

In sharing accommodation business such as Airbnb, while the provision of personalized amenities and services may seem like good business, hosts should be aware of the potential unintended consequences when they are not able to deliver what they promise. The present research examines how expectation gaps created by guest reviews interact with different types of preferential services to subsequently affect consumer behavior in the peer-to-peer accommodation economy. Grounded in attribution theory, this study offers new insights on customer responses to unfulfilled preferential treatment. The results suggest that in the condition of utilitarian services (e.g., airport transportation), participants in the low dispersion condition exhibited more negative attitudes, a lower level of repurchase intention, and a decreased willingness to write an online review. Conversely, in the condition of hedonic services (e.g., perform a talent show), expectation discrepancy did not result in different consumer evaluations across the dispersion conditions.
Is Your Food Organic? Examining the Role of Food Aesthetics in Restaurant Marketing
Authors: Yu Xi , Liu Stephanie Q.
Published: December 2021

Many restaurants believe that an aesthetically pleasing food presentation can help attract customers and elevate their evaluations. Yet the effectiveness of expressive aesthetics and the psychological processes associated with its use are not well understood in hospitality research. This study adopts a consumer behavior lens to explore how expressive aesthetics affects consumers’ decision making about organic versus conventional food in the restaurant setting. Findings reveal that the expressive aesthetics strategy is effective when marketing conventional, nonorganic food; however, such a strategy decreases consumers’ purchase intentions when the food is described as organic. Furthermore, an investigation of the underlying psychological mechanism indicates that anticipated pleasure and food temptation serially mediate the impacts of expressive aesthetics and food type on purchase intention.

Published: December 2021

The COVID-19 pandemic occurred during planned neurodevelopmental follow-up of Colombian children with antenatal Zika-virus exposure. The objective of the study was to leverage the institution's telemedicine infrastructure to support international clinical child outcome research. In a prospective cohort study of child neurodevelopment (NCT04398901), we used synchronous telemedicine to remotely train a research team and perform live observational assessments of children in Sabanalarga, Colombia. An observational motor and conceptional standardized tool kit was mailed to Colombia; other materials were translated and emailed; team training was done virtually. Children were recruited by team on the ground. Synchronous activities were video-recorded directly to two laptops, each with a telehealth Zoom link to allow simultaneous evaluation of “table” and “standing” activities, and backup recordings were captured directly on the device in Colombia. The U.S. team attended live over Zoom from four states and five distinct locations, made observational notes, and provided real-time feedback. Fifty-seven, 3–4-year-old children with Zika-virus exposure and 70 non-exposed controls were studied during 10 daytrips. Direct laptop recording ensured complete record of child activities due to internet outages. Telemedicine can be used to successfully perform international neurodevelopmental outcome research in children during the COVID-19 pandemic. Telemedicine can benefit global health studies.
Atypically slow processing of faces and non-faces in older autistic adults
Authors: Bathelt Joe , Koolschijn P Cédric MP , Geurts Hilde M
Published: December 2021

Face recognition is a fundamental function that requires holistic processing. Differences in face processing have been consistently identified in autistic children, but it is unknown whether these differences persist across the adult lifespan. Using event-related functional magnetic resonance imaging, we measured holistic face processing with a rapid Mooney faces task in 50 autistic and 49 non-autistic participants (30–74 years). Behavioral tasks included a self-paced version of the same paradigm and a global–local processing task (Navon). Reduced detection rates for faces, but not non-faces, were found in autistic adults, including slower responses on all conditions. Without time constraints, differences in accuracy disappeared between groups, although reaction times in correctly identifying faces remained higher in autistic adults. The functional magnetic resonance imaging results showed lower activation in the left and right superior frontal gyrus in the autism group but no age-related differences. Overall, our findings point toward slower information processing speed rather than a face recognition deficit in autistic adults. This suggests that face-processing differences are not a core feature of autism across the adult lifespan.

Lay abstract

Some theories suggested that social difficulties in autism arise from differences in the processing of faces. If face-processing difficulties are central to autism, then they should be as persistent as social difficulties across the lifespan. We tested this by asking autistic and neurotypical participants between 30 and 75 years to complete face detection tasks. Both autistic and neurotypical adults responded more slowly with age. When participants had to respond quickly, autistic adults made more errors in face detection regardless of their age. However, when the time constraint was removed, autistic adults performed as well as the neurotypical group. Across tasks, autistic adults responded more slowly when asked to detect both face and non-face stimuli. We also investigated brain activation differences in the face detection task with functional magnetic resonance imaging. The results indicated lower activation in the autism group in the left and right superior frontal gyrus. The superior frontal gyrus is not typically implicated in face processing but in more general processing, for example, keeping instructions in mind and following them. Together with the behavioral results, this suggests that there is no specific deficit in face processing in autistic adults between 30 and 75 years. Instead, the results suggest differences in general processing, particularly in the speed of processing. However, this needs to be investigated further with methods that are more sensitive to the timing of brain activation.

Magnetic resonance imaging is widely used for different diagnostic examinations involving autistic patients. The noisy, narrow, isolating magnetic resonance imaging environment and long scan times may not be suitable for autistic individuals, given their communication challenges, sensory sensitivities and often heightened anxiety. This systematic review aims to reveal any reasonable and feasible radiography-based adjustments to facilitate magnetic resonance imaging scanning without the use of sedation or general anaesthesia. Nine electronic databases were systematically searched. Out of 4442 articles screened, 53 were deemed directly relevant; when assessed against eligibility criteria, only 21 were finally included in this systematic review. Customising communication was found to be a key adjustment, as well as scan-based optimisation and environmental adaptations. The importance of distraction techniques and use of technology for familiarisation with the processes was also highlighted. The results of this study can inform recommendations to improve magnetic resonance imaging practice and patient experience, without the use of sedation or anaesthesia, where feasible. They can also inform the basis of dedicated training for magnetic resonance imaging radiographers.

Lay abstract

Autistic patients often undergo magnetic resonance imaging examinations. Within this environment, it is usual to feel anxious and overwhelmed by noises, lights or other people. The narrow scanners, the loud noises and the long examination time can easily cause panic attacks. This review aims to identify any adaptations for autistic individuals to have a magnetic resonance imaging scan without sedation or anaesthesia. Out of 4442 articles screened, 53 more relevant were evaluated and 21 were finally included in this study. Customising communication, different techniques to improve the environment, using technology for familiarisation and distraction have been used in previous studies. The results of this study can be used to make suggestions on how to improve magnetic resonance imaging practice and the autistic patient experience. They can also be used to create training for the healthcare professionals using the magnetic resonance imaging scanners.
Cognitive, social, and behavioral manifestations of the co-occurrence of autism spectrum disorder and attention-deficit/hyperactivity disorder: A systematic review
Authors: Rosello Rocio , Martinez-Raga Jose , Mira Alvaro , Pastor Juan Carlos , Solmi Marco , Cortese Samuele
Published: December 2021

Attention-deficit/hyperactivity disorder is one of the most common comorbidities in individuals with autism spectrum disorder. However, the clinical implications of the co-occurrence of these two disorders are still poorly understood. Based on a preregistered protocol (PROSPERO CRD42020193880), this systematic review identified 34 articles, published between January 1, 2014, and September 1, 2020, on cognitive, adaptive/social, and behavioral manifestations in children and adolescents with a diagnosis of autism spectrum disorder and attention-deficit/hyperactivity disorder (ASD+). The majority of available studies found a tendency toward a significant poorer cognitive performance in individuals with ASD+ compared with those with autism spectrum disorder alone (ASD−). The analysis of social/adaptive processes suggested that ASD+ is associated with lower functioning in comparison with ASD−. Finally, individuals with ASD+ were more likely to develop emotional/behavioral difficulties, in particular externalizing problems. Although some studies did not find differences among the two groups, overall co-occurring ASD+ may constitute a distinctive phenotype with a greater likelihood of cognitive, adaptive dysfunction, and mental health symptoms compared with ASD−. These results may inform the setting up and implementation of care pathways for individuals with attention-deficit/hyperactivity disorder and autism spectrum disorder.

Lay abstract

This work aimed to review recent research on the characteristics of individuals who have both autism spectrum disorder and attention-deficit/hyperactivity disorder due to their high co-occurrence. Thirty-four studies were analyzed and main findings summarized in two content domains focusing on areas that could enhance our understanding of the cognitive and behavioral characteristics of individuals with autism spectrum disorder + attention-deficit/hyperactivity disorder (ASD+). Most of the results suggested that ASD+ is a co-occurring condition associated with more severe impairments in cognitive functioning, adaptive behavior, and increased likelihood to present more emotional/behavioral problems. These results will be helpful to provide improved care plans for individuals with both attention-deficit/hyperactivity disorder and autism spectrum disorder.
A periodic seismic isolation foundation with an extremely broad low-frequency attenuation zone: Theoretical analysis and experimental verification
Authors: Zhou Peng , Wan Shui , Wang Xiao , Zhu Yingbo , Huang Muyun
Published: December 2021

The attenuation zones (AZs) of periodic structures can be used for seismic isolation design. To cover the dominant frequencies of more seismic waves, this paper proposes a new type of periodic isolation foundation (PIF) with an extremely wide low-frequency AZ of 3.31 Hz–17.01 Hz composed of optimized unit A with a wide AZ and optimized unit B with a low-frequency AZ. The two kinds of optimized units are obtained by topology optimization on the smallest periodic unit with the coupled finite element-genetic algorithm (GA) methodology. The transmission spectra of shear waves and P-waves through the proposed PIF of finite size are calculated, and the results show that the AZ of the PIF is approximately the superposition of the AZs of the two kinds of optimized units. Additionally, shake tests on a scale PIF specimen are performed to verify the attenuation performance for elastic waves within the designed AZs. Furthermore, numerical simulations show that the acceleration responses of the bridge structure with the proposed PIF are attenuated significantly compared to those with a concrete foundation under the action of different seismic waves. Therefore, the newly proposed PIF is a promising option for the reduction of seismic effects in engineering structures.
Resisting the resistance (journalism): Ben Smith, Ronan Farrow, and delineating boundaries of practice
Authors: Ferrucci Patrick , Canella Gino
Published: December 2021

In May 2020, New York Times media columnist Ben Smith critiqued Ronan Farrow, charging Farrow with practicing “resistance journalism.” Smith’s column generated significant discussion among journalists. This article analyzed the metajournalistic discourse that emerged following Smith’s column to examine how journalism’s boundaries are negotiated and contested. “Resistance journalism” has three main elements: it is unobjective, targeted, and truth-bending. “Resistance journalism” falls outside of the boundaries of journalism, according to the discourse, due to three practices: it lacks verification, focuses on narrative, and has a propensity to advocate. We argue that the current political economic and technological disruptions within digital media and networked society are creating new spaces for the rhetorical competition over journalism to occur, upending journalistic routines and creating hybrid journalism cultures.
Marketable religion: How game company Ubisoft commodified religion for a global audience
Authors: de Wildt Lars , Aupers Stef
Published: December 2021

Videogame companies are selling religion to an overwhelmingly secular demographic. Ubisoft, the biggest company in the world’s biggest cultural industry, created a best-selling franchise about a conflict over Biblical artefacts between Muslim Assassins and Christian Templars. Who decides to put religion into those games? How? And why? To find out, we interviewed 22 developers on the Assassin’s Creed franchise, including directors and writers. Based on those, we show that the “who” of Ubisoft is not a person but an industry: a de-personalized and codified process. How? Marketing, editorial and production teams curb creative teams into reproducing a formula: a depoliticized, universalized, and science-fictionalized “marketable religion.” Why? Because this marketable form of religious heritage can be consumed by everyone—regardless of cultural background or conviction. As such, this paper adds an empirically grounded perspective on the “who,” “why,” and “how” of cultural industries’ successful commodification of religious and cultural heritage.
Comparative Analysis of Attributions From Customer Experiences and Journeys
Authors: Gilliam David A. , Preston Teresa , Rockwell Casey C. , Hall John R.
Published: December 2021

This study developed a Comparative Analysis of Attributions method to explore sensemaking after customer experiences and journeys. Its foundation rests on the constructs of attribution theory by which actors make sense of the causes of events. Customer experiences and journeys involve both consumers and the firm’s employees interacting at touchpoints in a value co-creation attempt; each actor then makes attributions about the exchange experience. The qualitative inquiry compared attributions across actors after value co-creation (co-destruction) in a banking services context during the financial crisis. This showed how misunderstandings of one’s own and others’ sensemaking attributions can affect value co-creation during the customer experience and journey. The analysis thus offered managerially actionable information. Marketers may then improve internal and external messaging, touchpoints, and operations for better customer journeys. Academic researchers may use this method to map the continuum of attributional biases, errors, and styles across actors, industries, and contexts.
A baseline-free method for damage identification in pipes from local vibration mode pair frequencies
Authors: Esu Obukho E , Wang Ying , Chryssanthopoulos Marios K
Published: December 2021

As structural systems approach their end of service life, integrity assessment and condition monitoring during late life becomes necessary in order to identify damage due to age-related issues such as corrosion and fatigue and hence prevent failure. In this paper, a novel method of level 3 damage identification (i.e. detection, localisation and quantification) from local vibration mode pair (LVMP) frequencies is introduced. Detection is achieved by observation of LVMP frequencies within any of the vibration modes investigated while the location of the damage is predicted based on the ranking order of the LVMP frequency ratios and the damage is quantified in terms of material volume loss from pre-established quantification relations. The proposed method which is baseline-free (in the sense that it does not require vibration-based assessment or modal data from the undamaged state of the pipe) and solely frequency-dependent was found to be more than 90% accurate in detecting, locating and quantifying damage through a numerical verification study. It was also successfully assessed using experimental modal data obtained from laboratory tests performed on an aluminium pipe with artificially inflicted corrosion-like damage underscoring a novel concept in vibration-based damage identification for pipes.
‘Cognitive enhancers’: A qualitative exploration of university students’ experiences with prescription medicines for academic purposes
Authors: Monnet Fanny , Ergler Christina , Pilot Eva , Sushama Preeti , Green James
Published: December 2021

Qualitative work with students who use prescription medicines for academic purposes is limited. Thus, a more nuanced understanding of tertiary students’ experiences is urgently needed. Our study – which draws on five semi-structured interviews with New Zealand university students, complemented with information from local newspapers, blog entries and discussion forums – reveals students’ motivations and perceived effects, their risk perceptions and provides insights into the circumstances enabling the engagement with prescription medicines for academic purposes. Students were influenced by peers and social norms; and ideas about identity, morality and fairness also played a role for engaging with cognitive enhancers. Students used high levels of stress and workload to justify their use but took individual responsibility for their practices. By taking responsibility in this way, rather than considering it as a product of their environment, they buy into the neoliberal university discourse. Unexpectedly, some participants were already receiving medically justified psychopharmacological treatment but extended and supplemented this with nonmedical use. Others considered their use as being for academic emergencies, and that their low level of use helped manage risks. Overall, students viewed pharmacological cognitive enhancement for improving academic performance as cautious, safe, and morally acceptable. We argue in this paper that a local understanding of students’ motivations, justifications and perceptions of pharmacological cognitive enhancement is required, to tailor policies and support systems better to their needs and behaviours.
The Long-Term Effects of Living in a Shared and Continuous Traumatic Reality: The Case of Israeli Families on the Border With Gaza
Authors: Nuttman-Shwartz Orit
Published: December 2021

This article presents a literature review of the concept of intergenerational transmission of traumatic stress among a specific population of Israeli parents and children living near the Israeli/Gaza border, an area that can essentially be viewed as a laboratory of shared, continuous, and stressful reality resulting from ongoing political violence. The Google Scholar database was used to search only for peer-reviewed articles written in English and published between 2002 and 2020, and the particular focus of the study was Israeli families living in the “Gaza envelope”: communities that have been on the receiving end of rockets and mortars from Gaza for the past 20 years. The review was based on 35 articles and sheds light on the existence of studies using a variety of perspectives (e.g., psychological, biopsychosocial, and behavioral). Findings demonstrate the effects of continuous stress situations on the family dynamic, even before birth, among this small population. In addition, they show that to understand the unique process of intergenerational trauma transmission in a shared continuous traumatic reality, it is important to adopt a comprehensive perspective so as to understand the reciprocal, long-lasting, and transgenerational effects of being exposed to traumatic stress. This perspective can be used as a basis for developing family intervention strategies that are appropriate for preventing stress outcomes that derive from living in the context of persistent violence.
Effect of heat treatment on crystallinity and mechanical properties of flexible structures 3D printed with fused deposition modeling
Authors: Jayswal Ajay , Adanur Sabit
Published: December 2021

Fused Deposition Modeling (FDM) is a widely used 3D printing technique, which works based on the principle of melted polymer extrusion through nozzle(s) and depositing them on a build plate layer by layer. However, products manufactured with this method lack proper mechanical strength. In this work, 2/1 twill weave fabric structures are 3D printed using poly (lactic) acid (PLA). The ultimate tensile strength in the warp and weft directions and the modulus (stiffnesses) are measured for non-heat-treated (NHT) samples. The printed samples were heat-treated (HT) to improve the strength and stiffness. The variation in ultimate tensile strength is statistically insignificant in warp direction at all temperatures; however, the tensile strength in weft direction decreased after heat treatment. The modulus in warp direction increased by 31% after heat treatment while in the weft direction it decreased after heat treatment. Differential scanning calorimetry (DSC) tests showed the highest crystallinity at 125°C. The properties of the twill fabrics were compared with a standard dog-bone (DB) specimen using uniaxial tensile tests, Differential scanning calorimetry tests, and optical microscope (OM). For dog-bone specimens, the maximum values of crystallinity, ultimate tensile strength, and modulus were found to be at 125°C. The maximum crystallinity percentages are higher than that of the NHT samples. The ultimate tensile strength of NHT DB specimen 3D printed in horizontal orientation improved after heat treatment. The ultimate tensile strength of DB samples in vertical directions increased after heat treatment as well. The stiffness increased in both directions for DB samples.

Published: December 2021

Objective

Tobacco smoke exposure is a major risk factor for aortic aneurysm development. However, the initial aortic response to tobacco smoke, preceding aneurysm formation, is not well understood. We sought to create a model to determine the effect of solubilized tobacco smoke (STS) on the thoracic and abdominal aorta of mice as well as on cultured human aortic smooth muscle cells (HASMCs).

Methods

Tobacco smoke was solubilized and delivered to mice via implanted osmotic minipumps. Twenty male C57BL/6 mice received STS or vehicle infusion. The descending thoracic, suprarenal abdominal, and infrarenal abdominal segments of the aorta were assessed for elastic lamellar damage, smooth muscle cell phenotype, and infiltration of inflammatory cells. Cultured HASMCs grown in media containing STS were compared to cells grown in standard media in order to verify our in vivo findings.

Results

Tobacco smoke solution caused significantly more breaks in the elastic lamellae of the thoracic and abdominal aorta compared to control solution ( P< .0001) without inciting an inflammatory infiltrate. Elastin breaks occurred more frequently in the abdominal aorta than the thoracic aorta ( P < .01). Exposure to STS-induced aortic microdissections and downregulation of α-smooth muscle actin (α-SMA) by vascular smooth muscle cells (VSMCs). Treatment of cultured HASMCs with STS confirmed the decrease in α-SMA expression.

Conclusion

Delivery of STS via osmotic minipumps appears to be a promising model for investigating the early aortic response to tobacco smoke exposure. The initial effect of tobacco smoke exposure on the aorta is elastic lamellar damage and downregulation of (α-SMA) expression by VSMCs. Elastic lamellar damage occurs more frequently in the abdominal aorta than the thoracic aorta and does not seem to be mediated by the presence of macrophages or other inflammatory cells.

Published: December 2021

Background

This study aimed to evaluate a personalized 3D-printed percutaneous vertebroplasty positioning module and navigation template based on preoperative CT scan data that was designed to treat patients with vertebral compression fractures caused by osteoporosis.

Methods

A total of 22 patients with vertebral compression fractures admitted to our hospital were included in the study. Positioning was performed with the new 3D-printed positioning module, and the navigation template was used for patients in the experimental group, and the traditional perspective method was used for patients in the control group. The experimental group consisted of 11 patients, 2 males and 9 females, with a mean age of 67.27 ± 11.86 years (range: 48 to 80 years), and the control group consisted of 11 patients, 3 males and 8 females, with a mean age of 74.27 ± 7.24 years (range: 63 to 89 years). The puncture positioning duration, number of intraoperative fluoroscopy sessions, and preoperative and postoperative visual analog scale (VAS) scores were statistically analyzed in both groups.

Results

The experimental group had shorter puncture positioning durations and fewer intraoperative fluoroscopy sessions than the control group, and the differences were statistically significant (P < .05). There were no significant differences in age or preoperative or postoperative VAS scores between the two groups (P > .05).

Conclusions

The new 3D-printed vertebroplasty positioning module and navigation template shortened the operation time and reduced the number of intraoperative fluoroscopy sessions. It also reduced the difficulty in performing percutaneous vertebroplasty and influenced the learning curve of senior doctors learning this operation to a certain degree.

Background. Droplet simulation often requires expensive and inaccessible equipment. Herein, we develop and assess a low-cost droplet simulation model using easily accessible materials, open-source software, and a smartphone-based cobalt blue light. Methods. The simulation model was developed using commercial-grade materials and fluorescein dye. A clear face shield was assessed ten times following a simulated cough using fluorescein dye. A conventional ultraviolet Woods lamp was compared to a smartphone-based cobalt blue light to detect fluorescein illumination. Results. The simulation platform and smartphone-based cobalt blue light cost $20.18. A Wilcoxon signed rank test revealed that the median droplet area of fluorescence under the UV Wood’s lamp was not significantly different than that of the smartphone-based cobalt blue light (2.89 vs 2.94, P = .386). Conclusions. This simulation model is inexpensive and easily reproducible. The smartphone application may be a convenient alternative to standard ultraviolet lights. This model has great potential for use in financially restricted academic centers during the COVID-19 pandemic and beyond.
Music in Waiting Rooms: A Literature Review
Authors: Lai James C.-Y. , Amaladoss Noel
Published: December 2021

Objective:

We aim to review existing literature on the effects of background music in waiting rooms on patients. Furthermore, we examine existing neurobiological research for potential mechanisms by which music may affect patients.

Background:

Music has been studied in healthcare in various forms, from formal interventions such as music therapy to passive listening as therapy. However, music is also present in the healthcare environment in the form of background music in waiting rooms. There has been interest in whether background music in such a setting may have beneficial effects on patient anxiety in order to potentially inform healthcare workers whether and what type of music may be suitable for waiting rooms.

Methods:

We reviewed existing literature on music in healthcare waiting rooms and the neurobiological mechanisms by which music affects anxiety.

Results:

We located several small studies performed in a range of settings, including physician office waiting rooms and preoperative waiting areas. The studies generally reported that most patients viewed music in these areas positively; some, but not all, studies showed positive effects on patient anxiety. A variety of theories by which music may impact patient anxiety was noted.

Conclusions:

We conclude that there exists some evidence to support an anxiety-reducing effect of background music on patients, though studies vary widely in methodology and music selection. A small amount of neurobiological research into the pertinent mechanisms has been conducted, but further research will be required to elucidate the exact mechanisms by which this intervention may reduce anxiety.
Association of Ankle Dorsiflexion and Landing Forces in Jumping Athletes

Published: December 2021

Background:

Dorsiflexion range of motion restriction has been associated with patellar tendinopathy, but the mechanisms of how dorsiflexion restriction could contribute to knee overload remain unknown.

Hypothesis:

Peak ankle dorsiflexion and ankle dorsiflexion excursion are negatively associated with peak vertical ground-reaction force (vGRF) and loading rate, and with peak patellar tendon force and loading rate, and positively associated with peak ankle plantar flexor moment.

Study Design:

Cross-sectional study.

Level of Evidence:

Level 4.

Methods:

Kinematic and kinetic data of 26 healthy recreational jumping athletes were measured during a single-leg drop vertical jump. Pearson’s correlation coefficients were calculated to establish the association between peak ankle dorsiflexion and ankle dorsiflexion excursion with peak vGRF and vGRF loading rate, with peak patellar tendon force and patellar tendon force loading rate, and with peak ankle plantar flexor moment.

Results:

Ankle dorsiflexion excursion negatively correlated with peak vGRF loading rate ( r = −0.49; P = 0.011) and positively correlated with peak ankle flexor plantar moment ( r = 0.52; P = 0.006). In addition, there was a positive correlation between peak ankle dorsiflexion and peak vGRF ( r = 0.39; P = 0.05).

Conclusion:

Ankle kinematics are associated with vGRF loading rate, ankle flexor plantar moment and peak vGRF influencing knee loads, but no association was observed between ankle kinematics and patellar tendon loads.

Clinical Relevance:

These results suggest that increasing ankle dorsiflexion excursion may be an important strategy to reduce lower limb loads during landings but should not be viewed as the main factor for reducing patellar tendon force.
Endobronchial resection as a bridge to curative resection in patient with poor preoperative lung function secondary to an airway blocking endobronchial carcinoid tumour

We present a 70-year-old gentleman with chronic cough with haemoptysis found to have left lower zone collapse on imaging. The bronchoscopy showed an endobronchial mass histologically of a non-secreting atypical carcinoid. Poor baseline lung function excluded surgical resection, and instead, he successfully underwent a bronchoscopic debulking procedure which improved his FEV1 to 84% and DLCO 83% predicted. Unfortunately, the tumour regrew, but the calculated percentage predicted postoperative for FEV1 (64%), and DLCO (65%) enabled definitive surgical resection to take place. Surgical resection remains the definite curative option for localised endobronchial atypical carcinoid tumours. Achieving this in proximal endobronchial carcinoid tumour is a challenge. We described an endoscopic tumour debulking procedure as a bridge for curative surgical resection in a patient with an inoperable proximal atypical carcinoid tumour due to poor predicted postoperative lung function. We highlighted the need to assess predicted postoperative lung function with functional and quantitative perfusion methods to aid surgical planning. Debulking the tumour by endoscopy can be used as a conduit to curative surgical resection in bronchial carcinoid tumour. The choice of calculating the percentage predicted values by either or both methods must be individualised based on tumour location and the probability of converting a lobectomy to a pneumonectomy. This precautionary approach could evaluate the postoperative lung function and morbidity and mortality risk if considering a pneumonectomy. Endoscopic debulking can be a successful bridge to a curative surgical resection aided by comprehensive preoperative lung function tests to predict postoperative lung values

Published: December 2021

Background

Controlling risk factors and lifestyle modification in coronary artery bypass graft (CABG) patients plays an important role and leads to the empowerment of these patients to take care of themselves. One way to empower these patients is to improve their self-efficacy and hope. This study aimed to investigate the effect of the planned discharge on cardiac self-efficacy and hope of CABG patients.

Methods

In this quasi-experimental study, the sample consisted of 60 people (30 in the intervention group and 30 in the control group). Data were collected using the Miller Hope Questionnaire and Sullivan Cardiac Self-Efficacy Questionnaire. Data analysis was performed using central indices of mean and standard deviation and Chi-square, t-tests and one-way analysis of variance. The software used for data analysis was SPSS version 19.

Results

The mean age of participants in the control group was 91/9 ± 86/91 and in the intervention, group was 33/7 ± 7/58. There was no significant difference between the demographic characteristics, heart self-efficacy and hope scores of the participants in the control and intervention groups. After the intervention, there was a meaningful statistical difference between the two groups at discharge time and 1 month afterward in both hope and cardiac heart self-efficacy scores ( p = 0.001, 0.0001).

Conclusion

In this study, the implementation of the discharge program was effective in increasing the hope and cardiac self-efficacy of CABG patients and the use of the discharge plan is recommended to improve the outcomes of these patients.
