Published: July 2023

AbstractPeople value the opportunity to exercise control over the environment or make their own choices. Recent studies have revealed that simply having the opportunity to make choices can facilitate memory performance, suggesting an interaction between reward (due to choice making) and memory systems. However, little is known about the electrophysiological basis of choice‐related memory. In the current study, we used scalp electroencephalography combined with a choice encoding task to examine the role of theta oscillations (which have been widely connected to reward and memory processing) in choice‐related memory formation. The encoding task had two conditions. In the choice condition, participants were asked to choose between two occluded memoranda by themselves, whereas in the fixed condition, the decision was made by the computer. Behavioral results showed the choice effect, with better performance in the choice condition than the fixed condition on the recognition test given after a 24‐h delay. Increases in theta power during an early latency of encoding period predicted successful memory formation in the choice condition, but not in the fixed condition. Furthermore, decreases in theta power during a late latency predicted successful memory formation in both the fixed and the choice conditions. Finally, we observed increased theta power in the choice condition compared to the fixed condition during an early latency of encoding period and decreased theta power in the choice condition compared to the fixed condition during a late latency. Our results suggest that theta oscillations play a significant role in choice‐related memory formation.

Authors: Pope Kirsty , Barclay Linda , Dixon Karen , Kent Fiona 
Published: July 2023

Introduction: The aim of this scoping review was to identify, organise and synthesise existing evidence in relation to the supervision of allied health students on clinical placement.Methods: Five databases were searched for peer reviewed articles published from 2000 onwards. Data were extracted and analysed according to approaches to supervision, and student and/or educator outcomes for different models used. Each outcome was aligned to modified Kirkpatrick levels of evaluation.Results: 39 articles were reviewed. The terms models and approaches were poorly defined and used interchangeably in the clinical placement literature. Studies varied in the methods employed and were typically of low to moderate methodological quality with a dominance of Kirkpatrick level 2a outcomes reported.Conclusions: This review has proposed a definition of supervision models to enable future research comparisons between models and to provide clarity to placement providers’ decision making. Overall evidence for reported outcomes is mixed and not strong enough to draw conclusions in favour of any one model. Approaches to supervision, not student ratio, may well be the catalyst for positive outcomes for all stakeholders and therefore should be the focus of future research.

The binding-energy differences for $$^{{163}}{\text{H}}{{{\text{o}}}^{{q + }}}$$ and $$^{{163}}{\text{D}}{{{\text{y}}}^{{q + }}}$$ ions with ionization degrees $$q = 38$$, 39, and 40 are calculated. The calculations are performed using the large-scale relativistic configuration-interaction and relativistic coupled-clusters methods. The contributions from quantum-electrodynamics, nuclear-recoil, and frequency-dependent Breit-interaction effects are taken into account. The final uncertainty does not exceed 1 eV. Combining the obtained results with the binding-energy difference for neutral atoms calculated in [I.M. Savelyev, M.Y. Kaygorodov, Y.S. Kozhedub, I.I. Tupitsyn, and V.M. Shabaev, Phys. Rev. A 105, 012806 (2022)], we get the secondary differences of the ion–atom binding energies. These values can be used to evaluate the amount of energy released in the electron capture process in $$^{{163}}{\text{Ho}}$$ atom (the Q value), provided mass differences of highly charged ions $$^{{163}}{\text{H}}{{{\text{o}}}^{{q + }}}$$ and $$^{{163}}{\text{D}}{{{\text{y}}}^{{q + }}}$$ is known from experiment. The Q value is required by experiments on the determination of the absolute scale of the electron neutrino mass by studying the beta-decay process.
First-principles study of the electronic and optical properties of Be atoms adsorbed stanene
Authors: Zhao Jingwei , Liu Guili , Jiao Gan , Zhang Guoying 
Published: July 2023

Two-dimensional stanene is limited in its application in nanoscale optoelectronic devices due to its zero-bandgap. Based on first-principles calculations of density functional theory, the effects of adsorption of Be atoms with different coverages and torsional deformation on the structure, electricity, and optics of stanene are systematically investigated. The adsorption of Be atoms makes stanene have an adjustable bandgap, the surface state is successfully transformed from a zero-bandgap quasi-metal to a semiconductor with a maximum bandgap of 0.260 eV, the change in Be atom coverage causes a blueshift of the absorption and reflection peaks. Torsional deformation can effectively adjust the bandgap of stanene, which varies from 0.278 eV to 0.110 eV. Torsion enhances the maximum absorption peak of light. Stanene is expected to be a candidate material for designing new nanoelectronic devices.

Abstract
Background
Drug resistant Mycobacterium tuberculosis prevention and care is a major challenge in Ethiopia. The World health organization has designated Ethiopia as one of the 30 high burden multi-drug resistant tuberculosis (MDR-TB) countries. There is limited information regarding genetic diversity and transmission dynamics of MDR-TB in Ethiopia.

Objective
To investigate the molecular epidemiology and transmission dynamics of MDR-TB strains using whole genome sequence (WGS) in the Amhara region.

Methods
Forty-five MDR-TB clinical isolates from Amhara region were collected between 2016 and 2018, and characterized using WGS and 24-loci Mycobacterium Interspersed Repetitive Units Variable Number of Tandem Repeats (MIRU-VNTR) typing. Clusters were defined based on the maximum distance of 12 single nucleotide polymorphisms (SNPs) or alleles as the upper threshold of genomic relatedness. Five or less SNPs or alleles distance or identical 24-loci VNTR typing is denoted as surrogate marker for recent transmission.

Results
Forty-one of the 45 isolates were analyzed by WGS and 44% (18/41) of the isolates were distributed into 4 clusters. Of the 41 MDR-TB isolates, 58.5% were classified as lineage 4, 36.5% lineage 3 and 5% lineage 1. Overall, TUR genotype (54%) was the predominant in MDR-TB strains. 41% (17/41) of the isolates were clustered into four WGS groups and the remaining isolates were unique strains. The predominant cluster (Cluster 1) was composed of nine isolates belonging to lineage 4 and of these, four isolates were in the recent transmission links.

Conclusions
Majority of MDR-TB strain cluster and predominance of TUR lineage in the Amhara region give rise to concerns for possible ongoing transmission. Efforts to strengthen TB laboratory to advance diagnosis, intensified active case finding, and expanded contact tracing activities are needed in order to improve rapid diagnosis and initiate early treatment. This would lead to the interruption of the transmission chain and stop the spread of MDR-TB in the Amhara region.
Spectrum of cardiac diseases among young and older adults defined by echocardiography at Jakaya Kikwete Cardiac Institute: A prospective cross-sectional study
Authors: Jonathan Irene Abela , Kifai Engerasiya , Chillo Pilly 
Published: July 2023

Abstract
Background
Cardiovascular diseases (CVDs) are a major cause of morbidity and mortality worldwide, with data showing an increasing trend. Previously uncommon, CVDs of lifestyle are now increasing in many Sub-Sahara African (SSA) countries including Tanzania. The study aimed at determining the spectrum and distribution of CVDs among young (< 45 years) and older (≥ 45 years) adults referred for echocardiography at Jakaya Kikwete Cardiac Institute (JKCI).

Methods
Hospital-based cross sectional study was conducted among adult patients referred for echocardiography at JKCI between July and December 2021. Patient’s socio-demographic and clinical characteristics were recorded. CVD diagnoses were made using established diagnostic criterias. Comparisons were done using chi-square test and student’s t-test. Multivariable logistic regression analysis was used to determine factors associated with abnormal echocardiography. A significance level was set at p-value < 0.05.

Results
In total 1,050 patients (750 old and 300 young adults) were enrolled. The mean ± SD age was 62.2 ± 10.4 years and 33.5 ± 7.4 years for older and young adults respectively. Hypertension was the commonest indication for echocardiography both in the young (31%) and older (80%) adults. Majority of older adults were found to have abnormal echocardiography (90.7%), while only 44.7% of the young adults had abnormal echocardiography (p < 0.001). For the older adults, the commonest diagnoses were HHD (70.3%), IHD (9.7%), and non-ischemic cardiomyopathy (6.1%) while for young adults, HHD (16.7%), non-ischemic cardiomyopathy (8%), RHD (8%) and MVP (4.3%) were the commonest. The differences in the echocardiographic diagnoses between young and older adults were statistically significant, p < 0.001. Being an older adult, hypertensive, overweight/obese were independently associated with abnormal echocardiography (p < 0.01).

Conclusion
Hypertensive heart disease is the most common diagnosis among adult patients referred for echocardiography at JKCI, both in young and older adults. Primary prevention, early detection and treatment of systemic hypertension should be reinforced in order to delay or prevent its complications.

Abstract
Background
Patients with malignancy are at a higher risk of developing nosocomial infections. However, limited studies investigated the clinical features and prognostic factors of nosocomial infections due to fungi in cancer patients. Herein, this study aims to investigate the clinical characteristics of in-hospital fungal infections and develop a nomogram to predict the risk of in-hospital death during fungal infection of hospitalized cancer patients.

Methods
This retrospective observational study enrolled cancer patients who experienced in-hospital fungal infections between September 2013 and September 2021. Univariate and multivariate logistic regression analyses were performed to identify independent predictors of in-hospital mortality. Variables demonstrating significant statistical differences in the multivariate analysis were utilized to construct a nomogram for personalized prediction of in-hospital death risk associated with nosocomial fungal infections. The predictive performance of the nomogram was evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis.

Results
A total of 216 participants were included in the study, of which 57 experienced in-hospital death. C.albicans was identified as the most prevalent fungal species (68.0%). Respiratory infection accounted for the highest proportion of fungal infections (59.0%), followed by intra-abdominal infection (8.8%). The multivariate regression analysis revealed that Eastern Cooperative Oncology Group Performance Status (ECOG-PS) 3–4 (odds ratio [OR] = 6.08, 95% confidence interval [CI]: 2.04–18.12), pulmonary metastases (OR = 2.76, 95%CI: 1.11–6.85), thrombocytopenia (OR = 2.58, 95%CI: 1.21–5.47), hypoalbuminemia (OR = 2.44, 95%CI: 1.22–4.90), and mechanical ventilation (OR = 2.64, 95%CI: 1.03–6.73) were independent risk factors of in-hospital death. A nomogram based on the identified risk factors was developed to predict the individual probability of in-hospital mortality. The nomogram demonstrated satisfactory performance in terms of classification ability (area under the curve [AUC]: 0.759), calibration ability, and net clinical benefit.

Conclusions
Fungi-related nosocomial infections are prevalent among cancer patients and are associated with poor prognosis. The constructed nomogram provides an invaluable tool for oncologists, enabling them to make timely and informed clinical decisions that offer substantial net clinical benefit to patients.
What is the role of global health and sustainable development in Swedish medical education? A qualitative study of key stakeholders’ perspectives
Authors: Velin Lotta , Svensson Pia , Alfvén Tobias , Agardh Anette 
Published: July 2023

Abstract
Background
Global health and sustainable development have increasingly been recognised as important parts of medical education, yet education on these issues remains fragmented and scarce. In 2020, a bill to reform the national medical curricula across all Swedish medical schools was introduced, including a greater emphasis on global health and sustainable development. This study aimed to explore the perspectives of key stakeholders in medical education on the role of global health and sustainable development in Swedish medical education.

Methods
This was a qualitative study based on semi-structured interviews with 11 key stakeholders in medical education, broadly defined as faculty board members (dean and/or vice-deans for medical education) and/or programme chairs representing six universities. Data were analysed using qualitative content analyis (QCA). The study was conducted according to the Consolidated Criteria for Reporting Qualitative research (COREQ) guidelines.

Results
Stakeholders discussed the challenges and opportunities associated with the modification of medical education, which was seen as necessary modernisation to fit the changing societal perception of the role of medical doctors. The anchoring process of redesigning the curriculum and integrating global health and sustainable development was discussed, with emphasis on ownership and mandate and the role of teachers and students in the process. Finding a shared understanding of global health and sustainable development was perceived as a challenge, associated with resistance due to fear of curriculum overload. To overcome this, integrating global health and sustainable development with other topics and developing existing components of the curricula were seen as important. Additionally, it was stressed that fostering capacity building and developing infrastructure, including utilization of digital tools and collaborations, were essential to ensure successful implementation.

Conclusions
Medical institutions should prepare future doctors to respond to the needs of a globalised world, which include knowledge of global health and sustainable development. However, conceptual uncertainties and questions about ownership remain among key stakeholders in medical education. Yet, key stakeholders also highlight that the inclusion of global health and sustainable development in the new curricula represents multiple overarching educational opportunities that can bring about necessary improvement.

Abstract
Background and aims
: It is important to determine the profile of long COVID (LC) symptoms within the scope of rehabilitation in Bangladesh. This study’s objective was to estimate the newly experienced long COVID symptoms needing rehabilitation by determining the prevalence and spectrum of impairments due to LC in Bangladesh.

Methods
A Cross-sectional household survey of 12,925 COVID-19 patients confirmed by RT-PCR from 24 testing facilities in Bangladesh. LC was diagnosed according to WHO working group definition. COVID-19 Yorkshire Rehabilitation Scale (C19-YRS) was used to determine the symptom responses, symptom severity, new long COVID symptoms, and scope of rehabilitation.

Results
The population proportion of LC symptoms requiring rehabilitation interventions are 0.22 [95% CI, 0.20–0.24] in Bangladeshi people diagnosed with SARS-CoV-2. Among them, 0.08 [95% CI, 0.07–0.09] had mild, 0.07 [95% CI, 0.06–0.09] had moderate, and 0.05 [95% CI, 0.04–0.06] had severe long COVID symptoms (LCS). There was a significant positive correlation between LCS and functional disabilities (r = 0.889, p < 0.001), while a negative correlation was observed between the severity of symptoms and overall health (r=-0.658, p < 0.001). In comparison to the pre-COVID status, 17 new LCS were observed and the increase in the scope of rehabilitation intervention among LCS ranged between 0.01 [95% CI, 0.001–0.01] and 0.21 [95% CI, 0.19–0.22]. In Bangladesh, 59% (n = 334) of the LC cases are out of reach for any rehabilitation interventions.

Conclusion
Nearly one-fourth of Bangladeshi Post-COVID-19 have long COVID (LC). Seventeen symptoms (LCS) were observed and more than half of the populations having long COVID are out of reach of any rehabilitation facilities.
Oral health and individuals with a lived experience of an eating disorder: a qualitative study
Authors: Patterson-Norrie Tiffany , Ramjan Lucie , Sousa Mariana S. , George Ajesh 
Published: July 2023

Abstract
Background
Limited evidence exists describing the impact to oral health when living with an eating disorder and the availability of information or access to oral health services. This study investigated the perceptions of individuals with a lived experience of an eating disorder specifically to understand their needs and recommendations for improving access to early intervention and oral health promotion.

Methods
Using purposive sampling a total of 12 semi-structured interviews were conducted with participants across Australia who had a lived experience of an eating disorder. A hybrid inductive and deductive approach to thematic analysis was used to construct salient themes and subthemes.

Results
Most participants had experienced some oral health manifestation as part of their eating disorder hence, many felt quite knowledgeable on the topic. Following their eating disorder many participants felt confident in engaging with dental services, although, barriers including embarrassment, shame, and cost compromised access at times. Participants felt strongly that greater emphasis on oral health promotion during an eating disorder was important and this may be achieved by increasing the availability of resources and using trusted non-dental health professionals like dietitians.

Conclusions
The need for oral health promotion while experiencing an eating disorder was evident, however, dentists can often be a costly option. Non-dental health professionals like dietitians working with clients with an eating disorder may be an acceptable alternative for closing this gap.
Comparative analysis of binary and one-class classification techniques for credit card fraud data
Authors: Leevy Joffrey L. , Hancock John , Khoshgoftaar Taghi M. 
Published: July 2023

AbstractThe yearly increase in incidents of credit card fraud can be attributed to the rapid growth of e-commerce. To address this issue, effective fraud detection methods are essential. Our research focuses on the Credit Card Fraud Detection Dataset, which is a widely used dataset that contains real-world transaction data and is characterized by high class imbalance. This dataset has the potential to serve as a benchmark for credit card fraud detection. Our work evaluates the effectiveness of two supervised learning classification techniques, binary classification and one-class classification, for credit card fraud detection. The performance of five binary-class classification (BCC) learners and three one-class classification (OCC) learners is evaluated. The metrics used are area under the precision-recall curve (AUPRC) and area under the receiver operating characteristic curve (AUC). Our results indicate that binary classification is a better approach for detecting credit card fraud than one-class classification, with the top binary classifier being CatBoost.
Can family determine competition within the college campus? the effect of family background on college students’ human capital accumulation
Authors: Li Chunling , Guo Yaping 
Published: July 2023

AbstractUsing the Panel Survey of Chinese University Students, this paper systematically analyzes the effect of family background on the human capital accumulation of college students. This study finds that family background has little influence in elite universities, where the selective elimination effect is a determinant. In nonelite universities, however, family background and cultural reproduction mechanisms have significant influence, although individual efforts also factor in the process. In vocational colleges, neither cultural reproduction nor meritocracy is significantly effective. The universalization of higher education has caused divergence in different types of institutions, sorting college students into different competitive fields with different rules. Both the cultural reproduction mechanism and the selective elimination hypothesis can be identified in all kinds of colleges, but their effect varies in relation to institutional types.
