Indocyanine Green as a Navigational Adjunct for Laparoscopic Ablation of Liver Tumors
Authors: Gerber David A. , Vonderau Jennifer S. , Iwai Yoshiko , Steele Paula , Serrano Pablo , Desai Chirag S.
Published: October 2022

Background

Minimally invasive operative approaches for resection and thermal ablation (eg, microwave, radiofrequency) of hepatocellular carcinoma (HCC) have been successfully implemented over the last two decades, although identifying tumors can be challenging. Successfully performing laparoscopic ablation requires real-time visualization and ultrasonography skills for direct placement of the ablation probe.

Methods

In this study, we introduce a novel adjunct to ultrasound imaging for tumors located near or on the surface of the liver via intravenous delivery of indocyanine green (ICG) dye. Non-resectable lesion(s) not amenable to percutaneous ablation were considered for laparoscopic microwave ablation. Each patient initially received a dose of .3125 mg ICG via peripheral IV.

Results

A total of 17 patients were included. There was brisk uptake of ICG throughout the liver parenchyma in under 2 minutes in 15 of 17 patients; the remaining 2 required a second dose of ICG. In 14 cases, a hypo-fluorescent perfusion pattern in the tumor was clearly identified.

Discussion

Integrating ICG and fluorescent imaging provides a complementary adjunct to ultrasound in identifying HCC nodules. While previous applications of ICG typically require injections several days prior to surgery or segmental injections, this study demonstrates a novel real-time application of ICG to aid surgeons with various experiences in laparoscopic-assisted ablation procedures for HCC.
Does Neoadjuvant Radiation Therapy Contribute to the Incidence of Pulmonary Complications Following Esophagectomy for Malignant Neoplasm?
Authors: Beier Matthew A. , Greenbaum Alissa A. , Kangas-Dick Aaron W. , August David A.
Published: October 2022

Background

Post-operative pulmonary complications (POPC) are common in patients undergoing esophagectomy and neoadjuvant radiotherapy may exacerbate POPC. This study assessed whether neoadjuvant radiation increases the incidence of POPC in patients undergoing esophagectomy for malignancy.

Methods

The American College of Surgeons-National Surgical Quality Improvement Program database files from 2016 to 2018 were queried for patients undergoing esophagectomy for malignancy. Inverse probability treatment weighting (IPTW) was used to create balanced cohorts in which the control group received neoadjuvant chemotherapy (nCT) and the treatment cohort received neoadjuvant chemoradiotherapy (nCRT). A subset analysis was performed on patients with pre-existing pulmonary disease (PEPD). Primary outcomes were POPC and 30-day mortality.

Results

The all-patient analysis did not demonstrate a consistent association between neoadjuvant radiation and POPC. However, in patients with PEPD, POPC occurred more often in the nCRT cohort. Comparing nCRT to nCT and after IPTW adjustment for confounders, there was higher odds of pneumonia (aOR = 3.0, P = .002), unplanned intubation (aOR = 2.0, P = .03), and extended mechanical ventilation (aOR = 3.6, P = .002).

Discussion

In esophageal cancer patients with PEPD that undergo nCRT vs nCT prior to esophagectomy, the greater risk of POPCs must be weighed against the potential for improved oncologic outcomes.
Gustatory Function of Patients With and Without Cholesteatoma Undergoing Middle Ear Surgery
Authors: Neumann Aline Sophie , Soyka Michael B. , Rushing Elisabeth J. , Röösli Christof
Published: October 2022

Objective:

To compare measured and perceived taste function before and after surgery of patients with chronic otitis media with cholesteatoma (OMCC) to patients without cholesteatoma (patients with chronic suppurative otitis media [CSOM] and patients with lateral skull base lesions [LSB]).

Methods:

This prospective cohort study included 29 patients undergoing surgery for unilateral OMCC. The chorda tympani nerve (CTN) was resected in 8 of these patients. Fourteen patients undergoing surgery for unilateral CSOM and 5 patients undergoing surgery for unilateral LSB (with CTN resection) served as the comparison group. Taste function was measured using taste strips on both sides of the tongue before surgery, 2 weeks postoperatively and 3 months postoperatively. The affected side of the tongue was compared to the unaffected side. A questionnaire on taste perception was completed at each visit.

Results:

Preoperatively, cholesteatoma patients showed higher taste strip scores than non-cholesteatoma patients, indicating a larger difference between the healthy and affected sides of the tongue. Despite this difference in measured taste function few cholesteatoma patients reported taste alteration before surgery (3/29 [10.3%]). Postoperatively, patients with CTN resection (OMCC patients with CTN resection and LSB patients) showed a decreased measured taste function. Subjectively, only approximately 20% of these patients reported taste alteration 3 months postoperatively.

Conclusions:

Before surgery, cholesteatoma patients displayed an impaired measured taste function compared to patients without cholesteatoma (CSOM, LSB). Subjectively this was often unnoticed. After surgery, despite removal of the CTN and consequent reduction of measured taste function, few patients reported taste alteration and subjective taste perception was seen to be improving. In regards to middle ear surgery, perceived taste function does not seem to reflect measured gustatory function.
Verification of the Bühlmann fPELA turbo faecal elastase assay on the Binding Site Optilite benchtop analyser
Authors: Handley Simon A , Dote Nikko P , Wanandy Troy , Prentice Louise
Published: October 2022

Background

Pancreatic elastase-1 (PE1) can be measured to assess exocrine activity of the pancreas. A semi-automated particle-enhanced, open-channel turbidimetric immunoassay has been introduced by Bühlmann (fPELA turbo, Bühlmann Laboratories AG, Schoenenbuch, Switzerland). Published evaluation data is lacking. We therefore verified performance of the assay on the Binding Site Optilite benchtop analyser and undertook a sample comparison with the DiaSorin PE1 assay on the Liaison.

Methods

Accuracy, imprecision, lower limit of quantitation (LLoQ) and linearity of the Bühlmann fPELA turbo assay on the Binding Site Optilite analyser was ascertained. Comparison with the DiaSorin Liaison PE1 assay was also undertaken. Difference between assays was evaluated using the Wilcoxon signed-rank test and method comparison was undertaken using Spearman’s rank correlation (rs), Bland–Altman and Passing–Bablok regression analyses.

Results

The fPELA turbo assay was linear between 5 and 2500 μg/g. The LLoQ was 5 µg/g. Intra- and inter-assay imprecision was <6%. There was a good agreement (rs = 0.92) and no significant bias (5.8 µg/g, P = 0.29) present between the Bühlmann fPELA turbo and DiaSorin PE1 assays.

Conclusion

The Bühlmann fPELA turbo assay performs well on the Binding Site Optilite analyser. Faecal elastase results are commutable between with Bühlmann fPELA turbo and DiaSorin Liaison PE1 assays.
Peer leaders in reproductive health: A job that ended up much more
Authors: Koren Ainat , Marchburn Coutney
Published: October 2022

Objective:

Adolescents’ unintended pregnancy and sexually transmitted infections have a significant impact on the individuals themselves and on society. Peer leaders are students trained to become role models and leaders who promote positive behaviour change in their schools and community. A few studies have examined the effects of taking the role of peer leaders on the teenagers themselves including the long-term benefits. The aim of this study was to enhance understanding of the peer leader experience as it relates to peer leaders themselves and to explore the lasting impact of their experience.

Design:

The study used an exploratory qualitative design.

Setting:

Included peer leaders were employed by a non-profit organisation working with Southeastern Massachusetts communities with a high teenage pregnancy rate.

Methods:

Qualitative research included individual semi-structured interviews with 18 past and present peer leaders. Interviews were recorded and transcribed verbatim. Data were coded and analysed for common themes.

Results:

Being a peer leader was a life-changing experience. The benefits varied from learning reproductive health content to developing life skills, friendships and long-lasting career-related skills. Being a member of a peer leader group provided an instant support group and a new circle of friends as well as a purpose. It also removed peer leaders from health risk behaviours. Their experience assisting others in need was rewarding as well as being a confidence builder. Through community service, the peer leaders changed their perceptions about and towards the needs of the people residing in their community.

Conclusion:

This study demonstrated the value of incorporating peer leaders in sexual and reproductive health programmes. The peer leader programme examined was not only instrumental in providing education in sexual health but it also created change in the lives of the peer leaders themselves, their families and communities.
When and Why Consumers React Negatively to Brand Acquisitions: A Values Authenticity Account
Authors: Biraglia Alessandro , Fuchs Christoph , Maira Elisa , Puntoni Stefano
Published: October 2022

Brand acquisitions are a popular growth strategy. However, both anecdotal evidence and initial empirical evidence suggest that acquisitions can harm the acquired brand. This article proposes and tests a theoretical framework that aims to explain when and why consumers react negatively to acquired brands. Across ten studies using different methods, research designs, product categories, and brands, the authors demonstrate that these negative brand reactions can be explained by the perceived loss of a brand's unique values. Building on this values authenticity account, they document that the negative effect of acquisitions depends on the acquired brand's values, brand age, leadership continuity, and the alignment between acquiring and acquired brands. The findings offer important theoretical and managerial implications, helping managers predict and mitigate the negative effects of acquisitions for brands.
Can grades be an effective form of feedback?
Authors: Guskey Thomas R.
Published: October 2022

Although grades are often portrayed as detrimental to students’ motivation and interest in learning, closer analysis of the evidence indicates that when used appropriately, grades can be a meaningful and effective form of feedback. Thomas R. Guskey clarifies how studies on grades are frequently misinterpreted, explains how grades offer important but insufficient information on students’ learning progress, and describes conditions that must be met for grades to serve as a meaningful and effective form of feedback for students.
Theory of action: The care and feeding of your mission
Authors: Andres Abby Javurek , Nordengren Chase
Published: October 2022

In education, we share a common commitment to supporting students’ growth and development, but we often have different ideas about what that support looks like. A theory of action describes how a specific education organization intends to work to create the outcomes it wants. Abby Javurek Andres and Chase Nordengren describe how to develop and enact a theory of action that meets the needs of the school community. The process involves bringing people together to gain understanding of the problem, learning what is going well and building a shared vision of success, and aligning communications and decision-making around the shared vision.
Policy Solutions: Reimagining assessment to be accountable to the student
Authors: Collins Jonathan E.
Published: October 2022

Using narrow test scores as the only means of accountability does not serve students, teachers, or schools. Jonathan E. Collins writes that policy makers and educators should consider accountability as an education system designed to be accountable to the best version of students. This means assessing outcomes that policy makers too easily overlook. It also means allowing teachers more freedom to engage their students in more creative ways.

Directed Motivational Currents in Second Language: Investigating the Effects of Positive and Negative Feedback on Energy Investment and Goal Commitment
Authors: Zarrinabadi Nourollah , Soleimani Masoumeh
Published: October 2022

This study examined the role of positive and negative feedback on goal commitment and energy investment among English as a foreign language learners who experienced directed motivational currents (DMCs). To this purpose, a systematic methodology was used to identify language learners with a DMC experience (six students, four females, two males, mean of age = 19.5). Semi-structured interviews were conducted with the participants. The results of qualitative content analysis indicated that the three key features of DMCs were found in participants’ motivational experiences. In addition, the results showed that positive feedback affected goal commitment in DMCs by increasing goal persistence and sense of self-efficacy, while negative feedback enhanced motivation in DMCs by reducing the discrepancy between current state with the well-defined target state. The results also showed that feedback had some affective consequences that influenced goal pursuit in DMCs.
Gender and foreignness in William Davenant's The Siege of Rhodes Parts One and Two (1656–1663)
Authors: Jackson Honor
Published: October 2022

William Davenant's The Siege of Rhodes plays, published and performed in two parts that straddle the Interregnum/Restoration boundary, constituted novel theatrical spectacles in a number of ways, and many of these innovations will have seemed foreign, in the sense of strange or unfamiliar to contemporary audiences. The plays celebrate their own strange ingenuity as an attractive facet, and this theme is mirrored in the foreignness of subject which centres on the Ottoman Empire's siege of Rhodes in 1522. This article shows that this results in a representation of foreignness, which is tied up most explicitly in the representation of gender and homosexuality, and which is surprisingly celebratory.
Perfusion management of arch-clamping technique in total arch replacement with frozen elephant trunk
Authors: Luo Cheng , Jia Bo , Li Chengnan , Ge Yipeng , Zhong Yongliang , Qiao Zhiyu , Wang Chuan , Sun Lizhong , Zhu Junming
Published: October 2022

A technique called arch-clamping was used at our institute to ensure perfusion of the lower body and brain during total arch replacement with frozen elephant trunk (TAR and FET). The aortic arch clamp is inserted between the left common carotid artery and the left subclavian artery after inserting the stented elephant trunk into the true lumen of the descending aorta during the procedure, and then clamps the aorta and graft together as the distal anastomotic edge of the aorta. After the arch clamp was in place, lower body perfusion was resumed through the femoral artery was resumed and time to circulatory arrest was reduced to approximately 4 min. Cardiopulmonary bypass (CPB) flow was gradually restored to full rate. Thereafter, the left carotid artery anastomosis was completed and rewarming began. Finally, during the rewarming period, other branches of the aortic arch and ascending aorta were reconstructed. In this paper, we describe the perfusion management strategy, discuss intraoperative monitoring parameters, and examine the feasibility of the technique from a perfusion perspective.

Authors: Longley Verity , Woodward-Nutt Kate , Turton Ailie J. , Stocking Katie , Checketts Matthew , Bamford Ann , Douglass Emma , Taylor Julie , Woodley Julie , Moule Pam , Vail Andy , Bowen Audrey
Published: October 2022

Objective

Investigate feasibility and acceptability of prism adaptation training for people with inattention (spatial neglect), early after stroke, during usual care.

Design

Phase II feasibility randomised controlled trial with 3:1 stratified allocation to standard occupational therapy with or without intervention, and nested process evaluation.

Setting

Ten hospital sites providing in-patient stroke services.

Participants

Screened positive for inattention more than one-week post-stroke; informal carers. Occupational therapists participated in qualitative interviews.

Intervention

Adjunctive prism adaptation training at the start of standard occupational therapy sessions for three weeks.

Main measures

Feasibility measures included recruitment and retention rates, intervention fidelity and attrition. Outcomes collected at baseline, 3 weeks and 12 weeks tested measures including Nottingham Extended Activities of Daily Living Scale. Acceptability was explored through qualitative interviews and structured questions.

Results

Eighty (31%) patients were eligible, 57 (71%) consented, 54 randomised (40:13, +1 exclusion) and 39 (74%) completed 12-week outcomes. Treatment fidelity was good: participants received median eight intervention sessions (IQR: 5, 12) lasting 4.7 min (IQR: 4.1, 5.0). All six serious adverse events were unrelated. There was no signal that patients allocated to intervention did better than controls. Twenty five of 35 recruited carers provided outcomes with excellent data completeness. Therapists, patients and carers found prism adaptation training acceptable.

Conclusions

It is feasible and acceptable to conduct a high-quality definitive trial of prism adaptation training within occupational therapy early after stroke in usual care setting, but difficult to justify given no sign of benefit over standard occupational therapy.

Antihypertensives in dementia: Good or bad for the brain?
Authors: Beishon Lucy , Haunton Victoria J , Panerai Ronney B
Published: October 2022

Hypertension is associated with both ageing and dementia. Despite this, optimal blood pressure targets in dementia remain unclear. Both high and low blood pressure are associated with poorer cognition. Changes in vascular physiology in dementia may increase the vulnerability of the brain to hypoperfusion associated with antihypertensives. We discuss the potential risks of antihypertensives in the context of altered cerebral haemodynamics, and evidence from antihypertensive trials in dementia. We suggest that individualised blood pressure targets should be the focus for antihypertensive therapy in dementia, rather than strict control to uniform targets extrapolated from trials in cognitively healthy individuals.
Transformative Luxury Research (TLR): An Agenda to Advance Luxury for Well-Being
Authors: Batat Wided
Published: October 2022

This article lays the foundations for an emerging research stream introducing a new framework: transformative luxury research (TLR). The framework conceptualizes the relationship between the luxury ecosystem and people's well-being, which is affected by the interaction between luxury production and consumption entities as well as macroenvironment elements. The TLR framework lies at the intersection of luxury research, macromarketing literature, and transformative consumer research. The framework focuses on the well-being of individuals and communities involved in the luxury field. TLR provides a holistic view of how interactions between the luxury consumption sphere, including different profiles of consumers, and the entities of the luxury production sphere (e.g., employees, suppliers, organizations, and communities), are shaped by macro-level luxury stakeholders. Among them are institutions, public policymakers, academics, and technology firms. How do they all affect the individual and collective well-being at the economic, cognitive, emotional, and social levels? This framework helps scholars embrace a transformative luxury research mindset to advance the literature examining the impact luxury has on people's well-being.
Comparison of locking compression plate and distal femoral replacement for periprosthetic distal femoral fractures: a retrospective study
Authors: Fu Peng , Liang Wenwei , Gao Zhenzhen , Zheng Song , Fan Weimin
Published: October 2022

Objective

To compare the clinical outcomes of locking compression plate (LCP) and distal femoral replacement (DFR) for periprosthetic distal femoral fractures (PDFFs) after total knee arthroplasty.

Methods

This retrospective study identified patients with PDFFs in an institutional database between January 2012 and December 2021. Demographic data and clinical outcomes, including postoperative complications, reoperation, 1-year mortality, Knee Society Scores (KSS) and Knee Society Functional Score (KSFS) were analysed.

Results

In total, 12 patients treated with LCP and six patients treated with DFR were included. There was no significant difference between the LCP and DFR groups in terms of postoperative complications (25.0% versus 33.3%, respectively), reoperation (8.3% versus 0.0%), respectively, 1-year mortality (8.3% versus 16.7%, respectively) or mean ± SD KSS (80.3 ± 8.3 versus 78.0 ± 2.5, respectively). However, the mean ± SD KSFS was significantly better for patients with LCP than for those with DFR (51.8 ± 12.5 versus 37.0 ± 6.7, respectively).

Conclusion

DFR provides similar clinical outcomes compared with LCP for PDFFs. Patients with advanced age may benefit from DFR to allow early weight bearing.
A study of the analgesic efficacy of rectus sheath block in single-port total laparoscopic hysterectomy: a randomized controlled study
Authors: Choi Byung Jo , Choi Se Gyu , Ryeon Ohnchae , Kwon Woojin
Published: October 2022

Objective

To investigate the postoperative analgesic effects of rectus sheath block (RSB) in combination with patient-controlled analgesia (PCA) compared with PCA alone after single-port total laparoscopic hysterectomy (TLH)

Methods

This randomized, single-blind study enrolled female patients that underwent single-port TLH. The patients were randomized to receive either fentanyl PCA (PCA group) or RSB with the same PCA. The primary outcomes were fentanyl consumption at 8 h postoperatively and visual analogue scale (VAS) pain scores, which represented the severity of postoperative pain.

Results

A total of 36 patients were enrolled in the study: 18 in the PCA group and 18 in the RSB group (two patients were excluded). The primary outcome of fentanyl consumption was significantly lower at 8 h postoperatively in the RSB group than in the PCA group (148 ± 61 µg versus 222 ± 107 µg, respectively). VAS scores were significantly lower at arrival in the post-anaesthesia care unit and at 30 min after arrival in the RSB group compared with the PCA group. There were no significant differences in the nausea/vomiting score and in additional analgesic consumption between the two groups.

Conclusions

RSB can be used as a multimodal approach for pain control in single-port TLH procedures. Clinical Research Information Service (no. KCT0001461).
Zoonotic Politics: The Impossible Bordering of the Leaky Boundaries of Species
Authors: Cudworth Erika , Hobden Stephen
Published: October 2022

Zoonotic pandemics shine an uncomfortable light on how human lifeways facilitate the sharing of pathogens across species. Yet our lack of acknowledgement of our shared vulnerability with those non-human animals we raise or hunt to kill and eat, whose habitats we encroach upon and destroy, whose populations we undermine and threaten, has led us to the current human health crisis. The predominant political response to zoonotic pandemic has been bordering practices of surveillance, securitisation and bodily separation. These practices reflect intra-human and species hierarchies. They also fail to acknowledge the extent to which the boundaries of species are leaky, and are continually breached. A posthumanist zoonotic politics seeks not to attempt to border the leaky boundaries of species, but rather to insist on a re-ordering of species relations towards less exploitative and extractive ways of sharing the planet with the myriad creatures that constitute our world.

Optimization of the Self-Healing Efficiency of Bacterial Concrete Using Impregnation of Three Different Precursors into Lightweight Aggregate
Authors: Omar Omar , Mousa Momen R. , Hassan Marwa , Hungria Ricardo , Gavilanes Andrea , Arce Gabriel , Milla Jose , Rupnow Tyson
Published: October 2022

Implementation of self-healing concrete technologies is a promising approach to enhance the durability of the transportation infrastructure. Among these technologies, bacterial concrete has the potential to seal microcracks through microbial-induced calcite precipitation (MICP). To ensure the viability of this technology, bacterial protection is essential given concrete’s harsh environment. Additionally, the success of this technology depends on the presence of an adequate mineral precursor compound and nutrient for the bacteria. As such, the main objective of this study was to optimize the healing efficiency of bacterial concrete in subtropical climates through the vacuum impregnation of bacteria into a lightweight aggregate (LWA). To achieve this objective, mortar samples were prepared while incorporating different combinations of precursors (magnesium acetate, calcium lactate, and sodium lactate) and alkali-resistant healing agent Bacillus pseudofirmus bacteria (with and without). In addition, a control sample was prepared without bacteria or precursors for comparative purposes. For each sample, three mortar cubes and three mortar beams were cast and used to evaluate the compressive strength, crack healing efficiency, and flexural strength recovery. Additionally, the morphology of healing products was observed in bacteria-containing samples under scanning electron microscopy with energy x-ray dispersive spectroscopy using a scanning electron microscope (SEM) with EDAX Pegasus energy dispersive spectroscopy (EDS). Results showed that self-healing bacterial concrete could be optimized (without significant reduction in mechanical properties) if Bacillus pseudofirmus bacteria at a concentration of 108 cells/ml and sodium lactate precursor at a concentration of 75 mM/l were impregnated into lightweight aggregate.

Published: October 2022

Background:

Sports levels, baseline patient-reported outcome measures (PROMs), and surgical procedures are correlated with the outcomes of anterior cruciate ligament reconstruction (ACLR). Machine learning may be superior to conventional statistical methods in making repeatable and accurate predictions.

Purpose:

To identify the best-performing machine learning models for predicting the objective and subjective clinical outcomes of ACLR and to determine the most important predictors.

Study Design:

Case-control study; Level of evidence, 3.

Methods:

A total of 432 patients who underwent anatomic double-bundle ACLR with hamstring tendon autograft between January 2010 and February 2019 were included in the machine learning analysis. A total of 15 predictive variables and 6 outcome variables were selected to validate the logistic regression, Gaussian naïve Bayes machine, random forest, Extreme Gradient Boosting (XGBoost), isotonically calibrated XGBoost, and sigmoid calibrated XGBoost models. For each clinical outcome, the best-performing model was determined using the area under the receiver operating characteristic curve (AUC), whereas the importance and direction of each predictive variable were demonstrated in a Shapley Additive Explanations summary plot.

Results:

The AUC and accuracy of the best-performing model, respectively, were 0.944 (excellent) and 98.6% for graft failure; 0.920 (excellent) and 91.4% for residual laxity; 0.930 (excellent) and 91.0% for failure to achieve the minimal clinically important difference (MCID) of the Lysholm score; 0.942 (excellent) and 95.1% for failure to achieve the MCID of the International Knee Documentation Committee (IKDC) score; 0.773 (fair) and 70.5% for return to preinjury sports; and 0.777 (fair) and 69.2% for return to pivoting sports. Medial meniscal resection, participation in competitive sports, and steep posterior tibial slope were top predictors of graft failure, whereas high-grade preoperative knee laxity, long follow-up period, and participation in competitive sports were top predictors of residual laxity. High preoperative Lysholm and IKDC scores were highly predictive of not achieving the MCIDs of PROMs. Young age, male sex, high preoperative IKDC score, and large graft diameter were important predictors of return to preinjury or pivoting sports.

Conclusion:

Machine learning analysis can provide reliable predictions for the objective and subjective clinical outcomes (graft failure, residual laxity, PROMs, and return to sports) of ACLR. Patient-specific evaluation and decision making are recommended before and after surgery.
C.W. Mills’ notion of the ‘social milieu’ and its relevance for contemporary society
Authors: Jacobs Keith , Malpas Jeff
Published: October 2022

In Mills’ sociological analysis, a central notion is the ‘social milieu’ which encapsulates ‘the social setting of a person that is directly open to his personal experience’. For Mills, sociology should entail an investigation of the set of relations and practices that are a feature of human experience. Understanding the significance of Mills’ approach, we argue, requires grasping the way the notion of ‘milieu’ or ‘setting’ itself draws upon spatial and topological notions – notions that have become prominent in much contemporary sociological thinking. From this perspective, Mills’ work turns out to be relevant as a corrective, both to the undue emphasis on empirical particularity that is evident in some contemporary sociology and to what Mills viewed as ‘abstract’ theorisation. A large part of the relevance of Mills’ work for contemporary sociological problems and challenges is thus to be found in the way his emphasis on situation (or ‘place’), as given through the idea of ‘milieu’, allows a more complex and encompassing approach.

Published: October 2022

Home care workers played critical roles in meeting the complex medical and social needs of homebound adults during COVID-19, yet their contributions remain underappreciated. This study characterizes home care workers’ roles during COVID-19 and examines how home care disruptions impacted homebound individuals and caregivers. Using a qualitative analysis of electronic medical records among a randomly sampled subset of homebound patients in a home-based primary care practice, we found that home care workers were essential in meeting existing and new needs of homebound individuals. Insufficient home care worker services, including unstable schedules and inadequate hours of paid care, became particularly disruptive, leading to risks for patients and their caregivers. Given their integral role on care teams, home care workers must be a policy focus to prepare for emergent situations and ensure that homebound individuals have access to high quality, stable home care.
Effectiveness of Feedback Based on Log File Analysis in Introductory Programming Courses
Authors: Meier Heidi , Lepp Marina
Published: October 2022

Especially in large courses, feedback is often given only on the final results; less attention is paid to the programming process. Today, however, some programming environments, e.g., Thonny, log activities during programming and have the functionality of replaying the programming process. This information can be used to provide feedback, and this knowledge can be integrated into practical sessions in the classroom. This study aimed to analyse how feedback based on logs affects exam results, task completion time, the number of runs, error messages, and pastes (of the whole group and beginners and non-beginners separately). An experiment was conducted in 2020 and 2021 in the course “Introduction to Programming”. Some groups received additional feedback on homework throughout the course based on log information; the remaining groups worked as usual. Based on the information received from the logs, general recommendations were also offered in the practical sessions. Our study showed that feedback based on logs improved mainly exam test results and programming task solving time among beginners. Therefore, it would be a good method to use, especially in beginner groups.
Injury effects of knee airbags on Chinese human dummy
Authors: Xu Shucai , Huang Binbing , Liu Dechun , Zhu Yong , Song Jiafeng
Published: October 2022

Two kinds of knee airbags and dummy crash simulation models are established, and the accuracy of the models is verified by comparing the knee module impact test data and CAE simulation data. A knee airbag and dummy crash simulation system is established, and the frontal collision finite element simulation of the Chinese 50th percentile dummy is carried out under the three conditions of no knee airbag, bottom-mounted knee airbag, and rear-mounted knee airbag. According to the regulations of China-New Car Assessment Program (CNCAP), the injury data of major body parts such as the head, chest, femur, and legs are compared and analyzed, and the differences in damage to the dummy caused by the bottom-mounted knee airbag, the non-knee airbag and the rear-mounted knee airbag are focused on. Conclusion: Compared with the HIII dummy with knee airbag, the chest compression and tibia compression force of the Chinese dummy with knee airbag are larger, and the compression force of femur is smaller; compared with the condition without knee airbag, the value of head acceleration, tibial index, chest deformation, etc of Chinese dummy can be reduced with knee airbag, but the tibial axial force and knee side displacement have increased; compared with the condition of the rear-mounted knee airbag, the bottom-mounted knee airbag has better protection performance for the dummy’s head, chest, upper leg, and lower leg, but the knee side displacement of bottom-mounted knee airbag is greater, and the axial compression of the tibia is greater. This paper can provide a theoretical basis for the design of knee airbag in the Chinese market and the development of Chinese human dummy.
Thermal scrutinization of magetohydrodynamics CuO engine oil nanofluid flow across a horizontal surface via Koo–Kleinstreuer–Li modeling: A thermal case study
Authors: Hussain Syed M , Shahzad Faisal , Jamshed Wasim , Ahmad Mohammad Kalimuddin , Rehman Zulfiqar , Ullah Imran
Published: October 2022

The current investigation aims to investigate the effects of ohmic heating, heat source, and adhesive dispersion in third-grade nanofluid flowing magnetohydrodynamics (MHD) boundary layer heat transmission using the Koo–Kleinstreuer–Li (KKL) model. As a basic fluid, copper oxide nano molecules are suspended in engine oil. The controlling formulas that regulate the fields of flow and heat conduction are partial differential equations (PDEs) which are then converted into models of nonlinear ordinary differential equations (ODEs) that use the necessary similarity conversions. The resulting ODEs are numerically resolved using the Keller-Box approach. The effects of different common liquids, nano molecule sizes, magnetic parameter, Prandtl, material constant, and Eckert numbers are described using diagrams and tables for the field of motion, the field of temperature, the rate of heat transfer, and the drag force factor. The results show that the speed, drag force, and nozzle number for copper oxide engine oil nanofluids are lower than that of the basic liquid, while the addition of nanoparticles raises the temperature. The drag force factor and the rate of heat transfer are both found to increase when the material constant rises.

Published: October 2022

This research presents the machinability analysis in face milling of Ti–3Al–2.5V alloys using TiAlN-coated carbide insert under dual nozzle minimum quantity lubrication (MQL) cooling conditions. The TiAlN-coated insert has several favorable characteristics like superior wear resistance, greater hardness, and high chemical stability at elevated temperatures. The performance capability of this cutting insert was assessed using machinability responses such as surface roughness, tool wear, and cutting temperature results. The improved quality finish was found with maximum Ra (0.823 µm) while the improved accuracy of flatness (0.044) was obtained even though the rotational speed of the face mill cutter ( N) was highest (1500 r/min). Likewise, an acceptable range of flank wear (0.058–0.118 mm) and a lower range of cutting temperature (65 °C–106.8 °C) was found due to the superior thermal characteristics of TiAlN coating, effective cooling, and lubricating capability of the dual nozzle MQL system in face milling to this alloy. Further, by using the entropy coupled multi-objective optimization ratio analysis method, the optimal value of milling parameters was computed as coolant flow rate ( Q) 50 ml/h, feed speed (vf) 200 mm/min, and rotational speed of the face mill cutter ( N) 500 r/min. At this optimal setting, the optimum Ra, VBc, and T were found as Ra = 0.596 µm; VBc = 0.058 mm, and T = 65 °C, respectively.

Voriconazole is an antifungal with known side effects of phototoxicity and photocarcinogenesis. We present a case of HPV-related multifocal squamous cell carcinoma in a 68-year-old man with HIV, due to accelerated photocarcinogenesis associated with long-term use of voriconazole. Histology confirmed SCC with HPV-related features and he was found to have metastases. Multifocal SCC is unusual in association with voriconazole and HIV infection and only one other case has been reported. It is important for clinicians to be aware of the photocarcinogenic effects of voriconazole, especially in patients with HIV.

Background

Evidence among key populations supports acceptability of HIV self-testing (HIVST) due to its privacy and convenience. However, insufficient research has been done among transgender women (TGW), especially in Latin America. Consequently, the aim of this study was to explore the acceptability, perceptions and recommendations for HIVST implementation among TGW in Buenos Aires.

Methods

A focus group was conducted in July 2019. Particpants were invited to touch and learn about a displayed HIVST kit. The following main topics were explored: acceptability, reasons for seeking self-testing, preferences for training, distribution, periodicity and recommendations for HIVST implementation.

Results

The sample consisted of 12 TGWs; mean age of 26 years (IQR = 22–28); 66% had history of sex-work. The main motivations for seeking HIVST were convenience, privacy, and usage to reduce stigma and discrimination by health-care providers. Recommendations for HIVST were: distribution from primary health centers and trans-sensitive centers; affordable price; assistance by peer health promoters; and the provision of clear written and video instructions.

Conclusions

Tailored implementation of HIVST can increase HIV testing rates, early detection, and linkage to HIV-care in this high-prevalence group. This study provided community-driven suggestions to inform and adapt an HIVST feasibility pilot study and future implementation in Argentina.
A service evaluation of current practices in the assessment of mental-health and referral for support following disclosure of sexual violence
Authors: Clarke Jenny , Hyde Alice , Caswell Rachel J
Published: October 2022

Sexual violence (SV) has significant impacts on physical, social and psychological wellbeing, with associated mental illness and suicide. Despite no specific guidelines regarding mental health and SV, recommendations suggest all patients should have the opportunity to discuss their mental health and be offered referrals for support. A service evaluation was performed at a large Sexual and Reproductive Health Service (SRHS) with n = 179 patient records reviewed between 30/07/2021 to 01/10/21, who had disclosed SV including n = 83 referred from Sexual Assault Referral Centres (SARC). Patient exclusions included duplicates and non-attendances. Data on patient demographics, mental health assessment and referral services were analysed. Referral services included Independent Sexual Violence Advisors (ISVAs), a specialist third sector organisation Rape and Sexual Violence Project (RSVP), and an inhouse specialist SV clinic, Abuse Survivors Clinic (ASC). Demographic analysis demonstrated that 43% of cases were aged over 25 years, 47% were 18–25 and 10% under 18. Females comprised 85% of cases. Mental health history was documented in 91% of SARC referrals, compared to 77% of patients who directly attended SRHS. Current mental health was assessed in 83% of SARC referral patients, compared to 75% of direct SRHS patients. RSVP was offered to 81% of patients, more than any other service. ISVA was offered to 40% of patients, and ASC was offered to 3% of patients. In total, 11% of patients were offered no service referrals. Findings suggest improvements should be made to ensure all patients have discussions around their mental health and are offered support services following SV disclosure. Further research is required to determine whether these changes improve patient outcomes.

Developing an inclusive policy agenda for ensuring sustainable development is a challenge for both developed and developing countries. The developing countries face challenges in designing policy that achieves sustainable development goals based on environmental awareness, and that is one of the main contributions of this research. By taking into account the SDG 13 (climate action) and 7 (clean and affordable energy) this study examines the influence of education, natural resource availability, financial development, urbanization, and economic growth for ASEAN nations from 1991 to 2018. For an empirical estimate, second-generation approaches are used. The findings demonstrate the energizing influence of renewable energy usage in altering the environmental quality. According to the empirical findings, renewable energy and education lower CO2 emissions by 0.46% and 0.22%, respectively. Financial development, urbanization, and natural resource depletion all have a 0.14%, 0.03%, and 0.08% impact on the environment, respectively. The heterogeneous causality analysis reveals the feedback effect, i.e., bidirectional causal links between education, carbon emissions, and the use of renewable energy. This empirical data implies that nations should enhance investment in renewable energy and education sectors, as well as prepare for renewable energy research and development, to ensure environmental sustainability. This research has policy implications for ASEAN countries in terms of renewable energy and education investments. Through this agenda, the objectives of SDG 13 and SDG 7 will be achieved, while SDG 4 will be targeted.

Published: October 2022

Purpose: The current study seeks to investigate the extent to which factors such as income and child support along with relationship factors such as family structure and communication with the custodial mother potentially mitigate overall parent satisfaction for African American noncustodial fathers (NCFs) with multi-partnered fertility (MPF). Methods: 163 noncustodial fathers without and with children other than the custodial parents were selected. An independent sample t-test was conducted to determine differences in satisfaction levels. Multiple linear regression was conducted to predict participants' overall level of parental involvement satisfaction by income, child support, and relationship factors. Results: The data illustrates the combined influence of income, child support, relationship factors, and family structure account for a significant amount of the variance in satisfaction. Fathers without MPF reported greater satisfaction levels. Conclusions: Future study is recommended to advance our understanding of the predictors of NCFs parent satisfaction among NCFs with and without MPF.
Editor's Anonymous: A Safe Place to Think About Journal Provocations
Authors: Rockmann Kevin W.
Published: October 2022

Since taking the helm of the Academy of Management Discoveries in 2020, I have been struck by many interesting and thoughtful discussions with other editors as to the purpose of our journals, the importance of writing, and translating the science of management and organizations to appeal to a wider readership. In the spirit of playful yet engaging discourse, I thought I would lay these issues out, along with some ideas that we’ve already enacted at AMD and some that may be a bit more provocative in nature.
