Opioid Prescribing Behaviors Among Surgical Intensive Care Unit Attending Physicians
Authors: Goodman Emily M. , Wells Allison , Jensen Hanna K. , Kalkwarf Kyle J.
Published: March 2022

Background

More than 5 million Americans misuse opioids. Six percent of patients who receive opioids for acute pain progress to chronic use; this increases with higher doses and longer prescriptions. Prescribing variation exists within trauma centers and after emergency surgery but has not been demonstrated among intensivists.

Methods

Milligram morphine equivalents (MME) per patient-ICU-day provided by eleven surgical intensivists were analyzed. The patients were separated into 2 groups based on their percentage of time intubated in the surgical ICU. Both study groups were compared using demographics and comorbidity scores. The attendings were divided into high- and low-prescribing groups based on their MME/pt-ICU-day for intubated patients, and bivariate statistical analyses were performed. A similar analysis compared surgery vs anesthesia intensivists.

Results

The analysis included 257 patients in the “long-vent group” (LVG) and 668 patients in the “short-vent group” (SVG). The average MME/pt-ICU-day for the LVG was 222. Despite no significant differences in age, sex, or Elixhauser Comorbidity Index, there was a 45% difference between the high- and low-prescribing physicians in the LVG (253.7 vs 175.4 MME/pt-ICU-day; P = .008). This difference was not observed for patients in the SVG (74.3 vs 93.1 MME/pt-ICU-day; P = .141) nor based on intensivist specialty (LVG: 217.9 vs 209.5 MME/pt-ICU-day; P = .8) (SVG: 79.0 vs 93.3 MME/pt-ICU-day; P = .288).

Published: March 2022

Introduction

In trauma patients using warfarin, current guidelines recommend computed tomography of the brain (CTH), 24-hour observation, and repeat CTH to monitor for stability. Despite growing evidence of uncommon delayed hemorrhage, this remains standard practice even in mild traumatic brain injury without intracranial hemorrhage (ICH). Our study sought to determine the incidence and outcomes of delayed ICH (DICH) in trauma patients on supra-therapeutic warfarin without initial ICH.

Methods

A retrospective, single institutional study was performed of all adult trauma patients (>18 years old) who presented on prehospital warfarin with an international normalized ratio (INR) >3 and initial CTH that did not demonstrate ICH. Each of these patients underwent subsequent CTH within 24 hours and any DICH was identified. Those who demonstrated DICH were further examined to identify potential risk factors and outcomes such as need for further imaging or surgical intervention. Analyses were performed using Fisher’s exact tests and Student’s t-tests.

Results

225 patients were identified from January 2015 to April 2021 that met inclusion criteria. Of those identified, only 3 (1.33%) were found to develop any DICH on routine repeat CTH. Identified characteristics did not reach statistical significance due to the low number of DICH. None of the patients with DICH went on to require intervention.

Conclusion

In patients with identified traumatic injury on supra-therapeutic warfarin, an initial CTH without identified ICH alone is an adequate survey. DICH in these patients is uncommon and routine reimaging within 24 hours is unlikely to change clinical management in patients with intact neurologic status.
Efficacy of 4D CT Scan in Re-operative Parathyroid Surgery
Authors: Cruz-Centeno Nelimar , Longoria-Dubocq Texell , Mendez-Latalladi William
Published: March 2022

Parathyroidectomy is the only cure for primary hyperparathyroidism and is effective in more than 95% of cases at initial surgical intervention. However, 2.5-5% of cases have recurrent or persistent disease. Pre-operative imaging is recommended in patients undergoing redo parathyroidectomy to localize the diseased gland. Parathyroid 4D CT scan is now widely used for localization and has been reported to have improved accuracy when compared to other imaging modalities. We conducted a retrospective study of all redo parathyroidectomies from 2017 to 2021 at a single tertiary parathyroid referral center. We evaluated pre-operative 4D CT scan results and compared them to intra-operative findings to determine if 4D CT scan correctly predicted the location of the diseased gland. 4D CT scan had a concordance of 87% with intra-operative findings. 4D CT scan is highly effective identifying parathyroid pathology in re-operative cases and can be used as a pre-operative tool to guide surgical management.

Published: March 2022

Objective

Validated assessment of procedural knowledge and skills with formative remediation is a foundational part of achieving surgical competency. High-fidelity simulation programs provide a unique area to assess resident proficiency and independence, as well as to assist in identifying residents in need of further practice. While several studies have validated the use of simulation to attain proficiency of specific technical skills, few have validated remediation pathways for their trainees objectively. In this descriptive analysis, we review 2 remediation pathways within our simulation training curricula and how these are used in assessments of resident proficiency.

Materials and Methods

Two methods of remediation were formulated for use in high-fidelity simulation labs. One remediation pathway was a summative process, where ultimate judgment of resident competency was assessed through intra-operative assessments of a holistic skill set. The second remediation pathway was a formative “coaching” process, where feedback is given at several intervals along the pathway towards a specific technical skills competence. All general surgery residents are enrolled in the longitudinal, simulation curricula.

Results

Approximately one-third of surgical residents entered into a remediation pathway for either of the high-fidelity simulation curricula. Both residents and faculty expressed support for the summative and formative remediation pathways as constructed. Residents who entered remediation pathways believed it was a beneficial exercise, and the most common feedback was that remediation principles should be expanded to all residents. Interestingly, faculty demonstrated stronger support for the formative coaching feedback model than the summative assessment model.

Conclusions

Through the complementary use of both formative and summative remediation pathways, resident competence can be enriched in a constructive, nonpunitive method for self-directed performance improvement. Both trainees and faculty express high satisfaction with programs explicitly organized to ensure that skills are rated through a standardized process.

Authors: Guiab Keren , Evans Teresa , Brigode William , Stamelos George , Sebekos Konstantinos , Siddiqi Mahwash , Capron Gweniviere , Kaminsky Matthew , Bokhari Faran
Published: March 2022

Background

Previous studies have examined how factors such as gender, education, type of training (MD or DO), and experience of the treating surgeon affect patient outcomes. We investigated patient complications after elective laparoscopic cholecystectomy based on surgeon characteristics.

Methods

A Medicare database was used to identify surgeon-specific data. The main outcome measure was the adjusted complication rates (ACR) for individual surgeons as reported by the ProPublica Surgeon Scorecard. Surgeon gender, type of training, medical school rank, years since graduation, procedure volume, and teaching status of the primary hospital affiliation were assessed for any association with increased ACR using logistic regression analysis. We explored the associations among procedure volume, years of experience, and ACR using Spearman correlation.

Results

1107 predominantly male (94.6%) surgeons were included. 94.4% were MDs and 34.5% were affiliated with teaching hospitals. Mean length of practice was 24 ± 9 years, and median surgeon procedure volume was 28 (IQR = 23, 37). Overall median ACR was 4.3%. Multivariate analysis demonstrated that surgeon gender ( P = .71), medical school rank, type of training ( P = .68), or hospital affiliation ( P = .77) did not have a significant impact on ACR. Increased surgeons’ years in practice (r = −.028, P = .35) and increased surgeon procedure volume (r = −.021, P = .49) were negatively associated with increased ACR.

Conclusion

Surgeon gender, type of training, medical school rank, or hospital affiliation had no impact on complications after laparoscopic cholecystectomy. Surgeon experience and procedure volume may have clinical implications for patient outcomes. Further studies to elucidate factors associated with surgeon quality and patient outcomes are necessary.

Published: March 2022

Background

For critically ill congenital diaphragmatic hernia (CDH) patients on high frequency oscillatory ventilation (HFOV), extracorporeal membrane oxygenation (ECMO), and/or inhaled nitric oxide (iNO), operative repair in the neonatal intensive care unit (NICU) has been proposed to avoid complications during transport to an operating room (OR). This study compared neonates with CDH who received herniorrhaphy in the NICU or OR, with a subgroup analysis considering only patients supported with ECMO.

Methods

Patients admitted to the NICU in the first 2 weeks of life at a free-standing children’s hospital between July 2004 and September 2021 were examined. Patients were categorized according to location of CDH repair, and impact on operative complications and survival was compared.

Results

185 patients were admitted to the NICU with posterolateral CDH and received operative repair. 48 cases were operated on at the bedside in the NICU and 137 in the OR. Patients repaired in the NICU had higher use of HFOV, pulmonary vasodilators, and ECMO (all P < .001). Children repaired in the NICU experienced significantly higher in-hospital death and overall mortality ( P < .001). However, in multivariate analysis, repair location was not a significant predictor of survival to discharge in patients receiving ECMO. No significant difference in surgical site infection was detected for operative location ( P = .773).

Discussion

Congenital diaphragmatic hernia repair in the NICU occurred more frequently among higher risk patients who experienced worse survival. The rate of surgical site infection appeared similar overall and across subgroups suggesting adequate sterility and technique for bedside procedures, when necessary, despite restricted access to advanced operative equipment.

Published: March 2022

Frail, geriatric patients with pelvic fractures can present differently than non-frail patients. Using the Clinical Frailty Scale(CFS), a retrospective analysis was conducted to determine the relationship between patients’ CFS and outcomes after pelvic fractures. We hypothesized that frail, geriatric trauma patients defined as a CFS>4 with pelvic fractures have worse outcomes than non-frail patients with a CFS≤4 despite similar injuries. All geriatric patients with pelvic fractures and documented CFS were included. Seventy patients were included, with 59% (n = 41) frail. The groups were compared with no difference in mortality. The frail group was older and were most likely discharged to a skilled nursing facility (65.8%). Non-frail were most likely discharged to acute rehab (52%). Frail had lower functional status at discharge (median: 14.5v.16, P = .015). Frail patients had worse overall outcomes in this analysis of geriatric pelvic fracture patients. Special attention should focus on this vulnerable population to ensure optimal treatment and outcomes.
Green composites using recycled plastic bags and pineapple fibers waste
Authors: Gandara Meriene , Zanini Noelle C , Mulinari Daniella R , Saron Clodoaldo , da Rosa Capri Maria
Published: March 2022

This study proposes that green composites using recycled plastic bags (PEr) extruded with pineapple fiber waste (PR) from a juice industry to increase pineapple’s economic value stimulate practices that prioritize recycling and development of new materials. PEr composites were prepared using PR as a filler, using different fiber loadings of 5, 10, and 15 wt%, and the use of a coupling agent, prepared via extrusion and injection molding. The samples were investigated by Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis, inflammability, mechanical tests (tensile, impact, and shore hardness), scanning electron microscopy, and water absorption tests. FTIR results demonstrated that the addition of PR to the PEr caused a decrease in the characteristic bands of neat PEr, evidencing the chemical interactions. Thermal analysis showed that the addition PR decreased composites' thermal stability, causing relatively higher percentages of char compared to neat PEr, which increased the burning rate of composites, except for PEr/15PR and PEr/5PR-C. Green composites exhibited higher tensile modulus and hardness than PEr, but the impact tests presented a decrease in the fibers' addition to the PEr due to the reduction of toughness and resilience. SEM of fractured surface composites presented microcracks, voids, and fibers breakage in the interface. The composites showed low water absorption (up to 0.804%). The coupling agent’s use presented a low influence on the mechanical and thermal properties and a slight decrease in water absorption. These results demonstrate o potential of the reuse of plastic bags and industrial waste for green composites.
Influence of glass fibre reinforced polymer composite pin reinforcement on shear and dynamic behaviour of composite joint manufactured through co-cure technique
Authors: Dhilipkumar Thulasidhas , Rajesh Murugan
Published: March 2022

The co-cure technique efficiently joins composite components in wings, ailerons, skins, ribs and spars in aeronautical applications. The present study investigates the effect of through-thickness reinforcement of glass fibre reinforced polymer composite pin on shear and dynamic properties of co-cured composite joints. The experimental results exhibited that through-thickness reinforcement with 2% composite pin volume significantly improved the shear strength and elongation limit by 38.4% and 102.4% compared to unpinned joints. Furthermore, composite pin reinforcement changed the catastrophic failure of co-cured joints to progressive failure due to the tougher bridging traction of composite pins. The comparison of fractured surfaces exposed that debonding, composite pin pull-out and shear fracture of pins are the major failure mechanisms involved in enhanced shear strength and progressive failure of co-cured composite joints. The experimental modal analysis avowed that through-thickness reinforcement with 2% composite pin volume improved the fundamental natural frequency of the co-cure joints, while co-cure joint reinforced with higher volume (4%) of composite pins had higher damping value due to excessive fibre damage, which increased interaction between composite adherent and adhesive.
An Analysis of the Latent Class and Influencing Factors of Death Anxiety Among Han Chinese and Tibetan College Students
Authors: He Yiqing , Liang Jingyu , Guo Siping , Chen Lihua
Published: March 2022

In this study, 349 Han and 217 Tibetan college students were investigated via the Templer Death Anxiety Scale in order to assess the potential class and influencing factors of death anxiety among them. In addition, Mplus software was used to analyse the latent categories of their death anxiety, and an R3STEP approach was adopted to perform a multinomial logistic regression of its influencing factors. Whilst the results of the former indicated that there are two latent classes, respectively, defined as ‘high death anxiety type’ (Han 65.20%; Tibetan 30.30%) and ‘low death anxiety type’ (Han 34.80%; Tibetan 69.70%), the latter demonstrated that compared with the ‘low death anxiety type’, the occurrence ratio of the ‘high death anxiety type’ was 47.00 and 34.04 percentage points higher with each increase in age. Furthermore, the stress and anxiety of Han and Tibetan college students were found to constitute factors that affect death anxiety. More specifically, the death anxiety of Tibetan college students was determined to be deeply influenced by a belief in the afterlife.

Authors: Erbesler Zeynel A. , Demir Gokce
Published: March 2022

The aim of the study is to determine the levels of death anxiety and death-related depression in the elderly during the COVID-19 pandemic. The sample of the descriptive-relational study includes 344 elderly people registered in a family health center. It was determined that the most dreaded fear reported by the elderly who got COVID-19 infection was death, and there was a highly significant positive correlation between death anxiety and death-related depression ratings of the elderly and that as the average death anxiety score of the elderly rises, so does the degree of death-related depression.

Published: March 2022

Wuhan was the first large city where the initial breakout of COVID-19 took numerous lives. A group of social workers and mental health specialists coordinated the “Be Together Program” (BTP), a psychosocial grief intervention program to help a group of Wuhan COVID-19 bereaved people. Under the Dual-process model framework, BTP used the internet and social media as the main tools, combined with group and individual intervention. Additionally, it employed a “Supermarket Mode” with abundant intervention themes and approaches for BTP participants to choose according to their special needs. Additionally, Chinese cultural elements are integrated into the program. At the end of the program, the grief scores of participants in the qualified sample reduced significantly, and the prevalence of the potential Prolonged Grief Disorder diagnosis reduced from 75% to 12%. The study also found that the BTP was especially effective for those who had high levels of grief reaction.
An evaluation of a hot spot policing programme in four Argentinian cities
Authors: Chainey Spencer P , Estévez-Soto Patricio R , Pezzuchi Gastón , Serrano–Berthet Rodrigo
Published: March 2022

In 2017, hot spot policing interventions were implemented in four cities in Argentina: La Plata, Morón, Santa Fe and Tres de Febrero. Each intervention was similarly designed, organized and implemented. Results differed between cities. La Plata experienced the largest decreases, including a significant 31% decrease in robbery (while controlling for geographic displacement), whereas in other cities, a mix of non-significant decreases and increases in robbery and theft were observed. No displacement was observed to assaults or vehicle crime. The differences in impact between cities were likely to be associated with differences in the project management of each intervention.
Towards a constructed order of co-governance: Understanding the state–society dynamics of neighbourhood collaborative responses to COVID-19 in urban China
Authors: Liu Zhilin , Lin Sainan , Lu Tingting , Shen Yue , Liang Sisi
Published: March 2022

The state–society relationship in neighbourhood governance has been a focal topic in the urban governance literature, though the existing scholarship was primarily drawn from non-crisis situations. Adopting a mixed-methods approach, this study investigates the intricate state–society dynamics manifested at the neighbourhood scale as state and societal actors collaborated during China’s COVID-19 responses. Our study reveals a pattern of collaborative rather than confrontational dynamics between resident committees and other stakeholders during pandemic responses, which reflects the emergence of a constructed order of neighbourhood co-governance in urban China. Previous community-building reforms consolidated the political legitimacy, power and capacity of resident committees, which were empowered to play a critical coordinating role in bridging hierarchical state mobilisation and horizontal stakeholders in the collaborative pandemic responses. These findings contribute to a more nuanced understanding of neighbourhood co-governance in the international literature and provide lessons for resilience governance from a comparative lens.

Published: March 2022

Intimate Partner Violence (IPV) is a recurring phenomenon in society and can have important repercussions for the lives and health of women worldwide. Even in this alarming global scenario, many health workers still have difficulties approaching IPV with women and providing care for the victims of this type of violence. Given this context, this qualitative study aims at understanding how primary health care professionals provide care for women victims of violence by intimate partners. In view of the methodology design proposed in the Grounded Theory, data collection took place through theoretical sampling. Data collection was carried out in 22 institutions offering primary health care, with 31 female workers from different professional categories being interviewed individually and in depth, including physicians, nurses, dentists, psychologists, and social workers. The results show that, in order to overcome the difficulties encountered in caring for victims of IPV, primary health care workers have been developing strategies for the care of these women. These strategies include identification of such cases through questions about the woman’s intimate relationship, by establishing a bond with the victim so that she feels welcomed, and through articulation with other team professionals to propose expanded health care. The interventions carried out by these professionals include meeting the demands of women in the health institution where they work, referral to other services in the network, if necessary, and notification of IPV cases to epidemiological surveillance. Based on this understanding of the care offered by the professionals to women who are victims of IPV in primary health care, the research aims at contributing to the sensitization of professionals working in health institutions regarding the identification of signs that raise suspicion of IPV, as well as at addressing such cases in a way to fully meet these women’s needs.
Relationship Between Physical Activity, Coronary Artery Disease Risk Factors and Musculoskeletal Injuries in the City of Cape Town Fire and Rescue Service
Authors: Ras Jaron , Leach Lloyd
Published: March 2022

Musculoskeletal injuries in firefighters are a common occurrence, that increase as firefighters age, and may be related to the firefighters’ physical activity habits outside of the job. Certain CAD risk factors, such as obesity, cigarette smoking and ageing may be linked to increased injury risk in firefighters. Although firefighters may meet the recommended minimum physical activity minutes, they may remain at risk for sustaining musculoskeletal injuries. Therefore, this study aims to determine the relationship between physical activity and CAD risk factors, between CAD risk factors and musculoskeletal injuries and between physical activity and musculoskeletal injuries. A total of 124 full-time firefighters, males and females, were conveniently recruited from the City of Cape Town Fire and Rescue Service. A researcher-generated questionnaire was used to collect injury, CAD risk factor and physical activity data. The proportion of firefighters who participated in leisure-time physical activity (LTPA) was 63.7%, and those who were physically inactive was 69.4%. The prevalence musculoskeletal injuries among all firefighters was 27.4%. The most prevalent musculoskeletal injury was shoulder injuries in 35.3% of firefighters, followed by multiple injuries in 26.5% and back injuries in 14.7%. Age was a significant predictor of physical inactivity in firefighters [P = .002, OR = 1.08], BMI was a significant predictor of physical inactivity [P = .050, OR = 1.08], cigarette smoking was a significant predictor of firefighters not exercising [P = .007, OR = 2.31] and the total amount of vigorous-intensity exercise was a significant predictor of musculoskeletal injuries [P = .050, OR = 1.00]. In conclusion, older firefighters were more physically inactive and had a higher prevalence of musculoskeletal injuries, and the latter decreased significantly after the age of 50 years. Emphasis should be placed on firefighters exercising in their leisure-time, especially as they aged.
‘Acting under Chapter 7’: rhetorical entrapment, rhetorical hollowing, and the authorization of force in the UN Security Council, 1995–2017
Authors: Scherzinger Johannes
Published: March 2022

After more than 25 years of scholarship, the deliberative turn in international relations (IR) theory is ready to be revisited with a fresh perspective. Using new methods from automated text analyses, this explorative article investigates how rhetoric may bind action. It does so by building upon Schimmelfennig’s original account of rhetorical entrapment. To begin, I theorize the opposite of entrapment, which I call rhetorical hollowing. Rhetorical hollowing describes a situation in which actors use normative rhetoric, but instead of advancing their interests, such rhetoric fails to increase their chances of obtaining the desired outcome because the normative force of their rhetoric has eroded over time. To provide plausibility to both entrapment and hollowing, I present two mechanisms by which language is connected with action in the United Nations Security Council. Finally, I run a series of time-series-cross-section models on selected dictionary terms conducive to entrapment or hollowing on all speeches and an original Security Council resolution corpus from 1995 to 2017. The research shows that while mentioning ‘human rights’ is consistently associated with increased odds of authorization of force; the word ‘terrorism’ is associated with a decrease of odds for intervention. This finding suggests that some terms may not only entrap or hollow but also normatively backfire.
Comparative analysis by UV-vis and FT-IR spectroscopy of the chemical degradation of polyethylene used as greenhouse cover film
Authors: Belhachemi Asma , Maatoug M’hamed , Canela-Garayoa Ramon
Published: March 2022

Greenhouse culture usually requires a controlled environment for optimum plant growth and production. However, regular plastic films used for their coverage create an uncontrolled microclimate, especially in areas with harsh climatic conditions. Three low-density polyethylene (LDPE) films, a commercial ordinary film, a three-layer film, and a monolayer film were used as a greenhouse covering materials to study its behavior in presence of a cultivar and harsh climatic conditions. They were exposed to natural weathering and UV radiations in the semi-arid environment of a city located in northern Algeria. This study aims to investigate and compare the lifespan and deterioration of the materials used for a 5-month period to improve future greenhouse cultivation. Fourier-transform infrared spectroscopy (FT-IR) and ultraviolet-visible spectrophotometry (UV-vis) were used to study the aging and degradation of these films. FTIR 1030/2848 bands ratio was used to determine the chemical oxidation rate of each film. Visible changes in the material structure were also recorded during the aging process. Materials underwent photo and thermo degradation, leading to chemical and mechanical changes. The monolayer film has suffered more mechanical degradation than the multilayer films, leading to its total crumbling in a short lifetime. The three-layer and ordinary films were more resistant and showed approximately the same behavior towards the rough climatic conditions. Furthermore, the UV-visible spectrum indicated a high loss of transparency of the polyethylene films during their use. The two studied multilayer films seem more adequate for greenhouse culture under the semi-arid regions.
Domestic Military Deployments in Response to COVID-19
Authors: Erickson Peter , Kljajić Marko , Shelef Nadav
Published: March 2022

Militaries are commonly deployed in response to domestic disasters. However, our understanding of this phenomenon remains incomplete, partly because the particulars of disasters make it hard to generalize about deployments used in response. This article leverages the COVID-19 pandemic’s global reach to systematically evaluate common hypotheses about when and how militaries are used to respond to domestic disasters. It presents original global data about domestic military deployments in pandemic response and uses it to assess common theoretical expectations about what shapes whether and how militaries are used in such contexts. The results suggest that decisions about whether to deploy militaries stem from the securitization of domestic disaster relief rather than being responses to specific disaster-related features, state capacity shortcomings, or other social or political factors, even as some of these elements shaped how militaries were used. The article concludes by outlining some hypotheses for future research about the impact of this securitization on civil–military relations.
“To Live with Honor, or Die”: The Metamorphosis of Place, National Symbols, Masculinities, and Practices under State Terrorism (1973-1990)
Authors: Stern Claudia
Published: March 2022

This article explores the value of urban history and material culture in the study of memory. More specifically, it offers an examination through a masculine lens of the ways in which urban icons have impacted and shaped individual and national identities. The article focuses on Bulnes Square in Santiago de Chile and the Eternal Flame of Liberty as a key place and symbol of Augusto Pinochet’s “fascism in progress.” I draw on local press archives, advertising, and photographs to further explore the gender metaphor of state and nation as expressions of monolithic nationalism and their perpetuation of a hypermasculine tone, examining their links to place and national memory construction.
“If the Municipality Cannot Do It!”: Negotiating the Boundary between State and Society in Early Republican Turkish Cities
Authors: Hand Isaac
Published: March 2022

This article explores the ways in which debates about urban policy became a space for members of the literate Turkish public to negotiate the boundary between state and society during a period of dramatic social transformation in the 1930s. Inspired by circulating urbanist discourses, Turkish reformers reimagined society from street level up by passing a series of laws which empowered municipalities and abolished the neighborhood muhtar and council of elders, the basic units of local administration since 1829. Eleven years later, however, these offices were reconstituted and absorbed into municipal bureaucracy where they became the focus of heated party politics and struggles across Turkey. The debates which brought about this transformation, I argue, were ultimately about how far into daily life the authority of the government should extend and in what ways Turkey was able to adopt international standards of urbanism in a time of economic and political uncertainty.
Undergraduate Research Pools in Psychology Departments: Prevalence and Practices
Authors: Flynn Maureen K. , Rocheleau Courtney
Published: March 2022

Background

Limited research exists on the prevalence of undergraduate research participant pools (URPs) in psychology departments or guidelines surrounding their use.

Objective

The aim of the current study was to replicate older studies on the prevalence of URPs in the United States and the procedures and guidelines related to those requirements.

Method

Psychology department chairs in the U.S. were recruited by email and via the Association of Heads of Departments of Psychology listserv. A total of 604 department chairs participated in the online study by completing a series of assessments related to URP use in their department.

Results

Most 4-year institutions (67.7%), but few 2-year institutions (6.3%) had a URP. Of the 4-year institutions with a URP, 83.7% had a research requirement for students enrolled in their introduction to psychology courses. Most departments (84.0%) did not assess the educational value of research participation.

Conclusion

Most psychology departments have a URP, but few examined the educational value of research participation.

Teaching Implications

Psychology departments should identify learning objectives for research participation, assess outcomes, and identify practices that optimize achieving those objectives. Research requirements should be consistent with ethical principles and empirical evidence of learning.
How Relationships Foster Growth: Compassionate Goals Predict Growth-Seeking Through Perceived Available Support Independent of Relationship Security
Authors: Jiang Tao , Canevello Amy , Crocker Jennifer
Published: March 2022

Growth-seeking refers to a general tendency to pursue growth when facing challenges. The current studies examined whether and how benevolent intentions to support others and not harm them (i.e., compassionate goals in relationships) predict growth-seeking and whether this association is independent of relationship security, which may also predict growth-seeking. Two cross-sectional studies (Studies 1a and 1b, N = 1,032) and two longitudinal studies (Study 2: 3-wave weekly survey, N = 404; Study 3: 12-wave weekly survey, N = 230) showed that compassionate goals correlate with growth-seeking and predict increased growth-seeking over time through perceived available support. The results hold after controlling for participants’ (Studies 1–3) and their partners’ (Study 3) relationship security, which suggests that compassionate goals may foster growth-seeking through perceived available support independent of relationship security. In addition, Study 3 suggests an intrapersonal process (i.e., projected perceptions) underlying the link between compassionate goals and perceived available support.

Authors: Chowdhury Tanjim Istiaque , Hoque Md Rakibul , Wanke Peter , Raihan Mohammad Zahir , Azad Md Abul Kalam
Published: March 2022

Background

During COVID-19 lockdown worldwide, classroom education continues remotely through online. The question remains, comparing with the face-to-face education, does online education has a similar satisfaction level among the students? There are only a few studies that examine the perceived service quality of online education.

Objective

The study aims to analyze the factors of perceived service quality of online education during a pandemic.

Research Design

A structured questionnaire elicits information from 147 students from different study backgrounds of various universities worldwide. The fuzzy-set qualitative comparative analysis (fsQCA) is used for data analysis and model design. Research constructs evaluation for reliability and internal consistency are subsequently performed. A snowball random sampling method is applied for data collection.

Results

Findings from the fsQCA analysis identify four core factors that underpin student satisfaction through positive perceived service quality of online education. Alternative paths are determined based on gender, students’ current education status, and their loyalty toward online education. We also introduce two topologies of perceived quality regarding online education and student satisfaction.

Originality

Because of the primary nature of the data, this is firsthand experience gathered from different universities around the world who have willingly or unwillingly experienced online learning during the pandemic. The fsQCA technique for examining perceived service quality of online education.

Conclusions

Authors: de Bruijn Ymke , Emmen Rosanneke A. G. , Mesman Judi
Published: March 2022

Ethnic diversity and interethnic contact are increasing in Europe. Intergroup contact theory suggests interethnic contact to improve interethnic attitudes, but for young children, parental attitudes toward child interethnic relations might be an important factor determining whether they are exposed to these potentially positive contact effects. This study therefore examined maternal attitudes toward child contact with different ethnic outgroups among 251 mothers (137 White Dutch, 69 Turkish-Dutch, and 45 Afro-Dutch) of a 6- to 10-year-old child ( M = 7.51, SD = 0.98). Furthermore, associations between maternal attitudes toward child interethnic relations and child outgroup rejection were examined, as well as mediation effects of child actual outgroup contact. Neutral to positive maternal attitudes toward child interethnic relations were found, with relatively more negative attitudes among Turkish-Dutch than White Dutch and Afro-Dutch mothers, and toward child relations with Muslims as compared to another outgroup among White Dutch and Afro-Dutch mothers. Furthermore, results did not indicate that maternal attitudes were related to child actual outgroup contact or child outgroup prejudice and no support for the intergroup contact theory was found. These results suggest that intergroup contact theory does not easily apply, highlighting the need for more research on children in various populations and contexts using different measures and informants. Patterns from the present study suggest that most improvement in terms of maternal attitudes fostering child interethnic relations can be made in the interethnic relations including ethnic groups in the Netherlands that predominantly identify as Muslim.
Relational turbulence and social network engagement during the summer of COVID-19: A repeated measures, dyadic analysis
Authors: Brisini Kellie S. , Solomon Denise H.
Published: March 2022

Background/Purpose: Relational turbulence theory suggests that changes in and around relationships create the potential for relational turbulence when everyday routines and scripts are upended and communication becomes polarized. In turn, perceptions of a romantic relationship as chaotic or tumultuous can influence a person’s engagement with their social network. Alternately, previous research also suggests that engagement with friends and family has the potential to influence married partner’s relationship quality. Research Design: This study examined these propositions among a sample of married couples ( N = 64, 128 individuals) whose daily experiences and relationship dynamics changed during the COVID-19 lockdown period. Results/Conclusions: Based on a 10-week, weekly diary repeated measures design, results suggest that relational turbulence and the valence of social network engagement may be mutually influential, such that (a) relational turbulence may influence the way in which married partners interpret communication with social network members and (b) the valence of communication with social network members may influence experiences of relational turbulence.

Background

Regarding the overall inadequate results after cardiopulmonary resuscitation, the development of new treatment concepts is urgently needed. Controlled Automated Reperfusion of the whoLe body (CARL) represents a therapy bundle to control the conditions of reperfusion and the composition of the reperfusate after cardiac arrest (CA). The aim of this study was to investigate the plasma expander’s role in the CARL priming solution and examine its mechanism of action.

Methods

Viscosity, osmolality, colloid osmotic pressure (COP), pH and calcium binding of different priming solutions were measured in vitro and compared to in vivo data. N = 16 pigs were allocated to receive CARL following 20 min of untreated CA with either human albumin 20% (HA, N = 8) or gelatin polysuccinate 4% (GP, N = 8). Blood gas analyses were performed during the first hour of reperfusion and catecholamine and fluid requirements were recorded. Neurological outcome was assessed by neurological deficit scoring (NDS) on the seventh day.

Results

In vitro, addition of HA to the CARL priming solution resulted in higher COP and higher calcium-binding than GP. In vivo, treatment with HA led to greater reduction of ionized calcium and higher extracorporeal flows within the first 30 min of reperfusion with no difference in catecholamine support and fluid requirement. Seven-day survival of 75% with no difference in NDS was observed in both groups.

Conclusions

Our data show that the plasma expander in the CARL priming solution has a significant effect on the initial reperfusate and can potentially influence the course of resuscitation. However, seven-day survival and NDS did not differ between groups.

Background

To evaluate different aortic root surgery techniques and their contemporary clinical outcomes in patients with regurgitant aortic valve and aortic root aneurysm.

Methods

The study consisted of 141 adult patients who underwent aortic valve reimplantation (David group = 73) or aortic valve replacement surgery (Bentall group = 68) for aortic valve regurgitation (AR) and dilatation of the aortic root at our institution within the same period (April 2004–October 2016). Kaplan–Meier method was used to estimate survival and other clinically relevant outcomes between the groups.

Results

The completeness of clinical follow-up was 100%, with a mean time of 8.0 ± 3.8 years. Thirty-day (in-hospital) mortality rates were equivalent between groups (1.3 and 1.5%, p = 1.0). The overall survival rates at 10 years were significantly better for the David group patients comparing to Bentall group patients (95.3 ± 2.6% vs 79.7 ± 6.8%; p = 0.04) with similar freedom from AV related reoperation (94.4 ± 2.7% vs 98.5 ± 1.5%; p = 0.2). Freedom from bleeding events at 10 years was 90.7 ± 3.6% for Bentall group patients and none were observed among David group patients ( p = 0.01).

Conclusions

Aortic valve and root surgery can be performed with equivalent safety and efficacy using either valve-sparing (David procedure) or valve-replacing (Bentall procedure) techniques in selected patients. Furthermore, patients after the David procedure demonstrated significantly improved survival and low risk of bleeding in comparison to the Bentall procedure with an acceptable risk of reoperation at 10 years follow-up.
Longitudinal Within-Family Association Between Parental Monitoring and Adolescent Aggressive Behaviors: Mothering versus Fathering

This study using PROSPER data ( N = 977, age 11.5–age 15) investigated the longitudinal within-family associations between parent reported parental monitoring and adolescent aggression. Importantly, this study is the first one to examine parent gender and adolescent gender differences on these within-family associations. Results differed between mothers and fathers. There was a negative, bidirectional within-family association between maternal monitoring and adolescent aggression, such that more maternal monitoring than usual was associated with fewer adolescent aggressive behavior problems than usual within the same family, and vice versa. In contrast, during mid-adolescence, a positive, bidirectional within-family association between paternal monitoring and adolescent males’ aggression was found, such that more paternal monitoring than usual was related to more adolescent males’ aggression than usual within the same family, and vice versa. Practical implications on intervention strategies are discussed.

Published: March 2022

In this study, we identified (1) subgroups of youth during middle childhood who displayed distinct profiles of social emotional learning (SEL) skills including cooperation, prosocial behaviors, work habits, emotion regulation, and self-control; and (2) how these profiles predict longitudinal academic and social functioning during early adolescence. Using the NICHD SECCYD dataset ( N = 932, 49% girls), four profiles emerged: relatively low SEL (14%), moderate-high SEL (51%), prosocial/self-control (22%), and cooperation/work habits (13%). Longitudinally, the prosocial/self-control group and cooperation/work habits group demonstrated area-specific weakness. The prosocial/self-control youth were at risk of poor academic competence; the high cooperation/work habit youth were at risk of poor social functioning whereas the relatively low SEL skills youth demonstrated highest risk in poor academic and social functioning in early adolescence.
