Authors: Lee Magdalene Hui Min , Phua Dong Haur , Heng Kenneth Wei Jian 
Published: October 2021

Abstract
Background
The objective structured clinical examination (OSCE) is a part of emergency medicine (EM) examinations such as the Masters of Medicine in Emergency Medicine (MMed) examination and the equivalent Member of the Royal College of Emergency Medicine (MRCEM) examination. The use of formative OSCEs to prepare EM residents for summative OSCEs has not been investigated. This study aimed to evaluate the role of formative OSCEs in preparing EM residents for the MMed and MRCEM OSCE.

Methods
This was an observational, retrospective, mixed-methods cohort study. We analysed data from formative OSCEs conducted by the National Healthcare Group EM residency programme from 2013 to 2019, and from a questionnaire distributed to all residents during the study period. Residents’ formative OSCE participation and scores were compared with first-attempt summative OSCE success. Qualitative analysis of residents’ opinions on the usefulness of the formative OSCE was performed.

Results
Forty-three of the 50 (86.0%) residents attended at least one formative OSCE. Of the 46 who responded to the questionnaire, 40 (87.0%) had attempted and succeeded in the MMed or MRCEM OSCE, of whom 35 (87.5%) had succeeded on the first attempt. Residents who succeeded in the summative OSCE on the first attempt tended to have higher proximate (mean = 70.6, SD = 8.9 vs mean = 64.3, SD = 10.8) and mean (mean = 67.4, SD = 7.1 vs mean = 62.8, SD = 7.3) formative OSCE scores. All 8/40 (20.0%) residents who attended more than three formative OSCEs succeeded in the summative OSCE on their first attempt. Residents’ formative OSCE scores tended to improve with successive formative OSCEs, demonstrating a positive training effect. All residents felt that the formative OSCE was useful in preparing them for the summative OSCE.

Conclusions
Participation in multiple formative OSCEs was beneficial in preparing residents for the summative OSCE. The formative OSCE was useful in familiarising residents with the examination, giving them an opportunity to perform in near-examination conditions, and providing feedback to residents and faculty about their progress. Our findings may support the implementation of formative OSCEs in other training programmes to prepare learners for high-stake summative OSCEs.

Abstract
Background
This study aimed to evaluate the feasibility, safety, and efficacy of postoperative adjuvant chemotherapy with docetaxel/cisplatin/S-1 (DCS) following S-1 therapy in patients with stage III gastric cancer after curative gastrectomy.

Methods
Patients with stage III gastric cancer who underwent D2 gastrectomy were enrolled. Adjuvant chemotherapy was initiated within 8 weeks of gastrectomy. The first cycle of chemotherapy consisted of S-1 monotherapy (day 1–14), followed by a 7-day rest period. Cycles 2 and 3 consisted of the following: S-1 (day 1–14) administration, followed by a 14-day rest period, and an intravenous infusion of cisplatin and docetaxel on days 1 and 15. After two cycles, S-1 was administered for up to 1 year.

Results
Thirty patients were enrolled between 2014 and 2017. Febrile neutropenia of grade 3 or higher was the most common hematological toxicity with 4 patients (13.3%). Other hematological toxicities of grade 3 or higher were as follows: neutropenia in 3 (10.0%), leukopenia in 3 (10.0%), and anemia in 2 (6.7%) patients. Most frequent non-hematological toxicity of grade 3 was anorexia (n = 4, 13.3%) and general fatigue (n = 3, 10.0%); no grade 4 non-hematological toxicities were observed. Twenty-five patients (83.3%) completed two cycles of DCS treatment and 18 (60.0%) completed subsequent S-1 treatment for 1 year. The relative dose intensity of docetaxel and cisplatin was 0.86 and that of S-1 was 0.88.

Conclusion
The DCS regimen can be acceptable as an adjuvant chemotherapy and offers an effective postoperative treatment option for stage III gastric cancer patients.

Parental experience of the neuromotor development of children with congenital heart disease: an exploratory qualitative study
Authors: Mitteregger Elena , Wehrli Martina , Theiler Manuela , Logoteta Jana , Nast Irina , Seliner Brigitte , Latal Beatrice 
Published: October 2021

Abstract
Background
Children with severe congenital heart disease (CHD) are a group of children at risk for neurodevelopmental impairments. Motor development is the first domain to show a delay during the first year of life and may significantly contribute to parental concerns, stress, and difficulties in early child-parent attachment. Thus, the aim of the study was to better understand the wishes and concerns of parents of children with CHD and explore their experience of their children’s neuromotor development in the first year of life.

Methods
In this qualitative study, fourteen families were recruited. Their children were aged 1–3 years and had undergone open heart surgery within the first 6 months of life. Semi-structured interviews were audio-recorded and transcribed. The data was explored within an expert group, and a qualitative content analysis was conducted using VERBI MAXQDA software 2020. The study was conducted in accordance with the COREQ checklist.

Results
Parents of children with CHD reported several burdens and needs. Parental burdens concerned the child’s motor development, their own physical and psychological strain, and difficulties in communication with healthcare professionals. The needs, parents reported included supporting their child’s motor development, a medical coordinator, and better communication between healthcare professionals and parents. During the first phase of their children’s illness, parents underwent a dynamic transitional phase and expressed the need to rely on themselves, to trust their children’s abilities, and to regain self-determination in order to strengthen their self-confidence.

Conclusions
It is essential to involve parents of children with CHD at an early stage of decision-making. Parents are experts in their children and appreciate medical information provided by healthcare professionals. Interprofessional teamwork, partnering with parents, and continuous support are crucial to providing the best possible care for children and their families. Family-centred early motor intervention for CHD children might counteract the effect of parental overprotection and improve children’s motor development and thus strengthen child-parent interaction. In future work, we aim to evaluate a family-centred early motor intervention for children with CHD developed on the basis of this qualitative study.

Published: October 2021

Abstract
Background
Multidisciplinary team meetings (MDTMs) are part of the standard cancer care process in many European countries. In France, they are a mandatory condition in the authorization system for cancer care administration, with the goal to ensure that all new patients diagnosed with cancer are presented in MDTMs.

Aim
Identify the factors associated with non-presentation or unknown presentation in MDTMs, and study the impact of presentation in MDTMs on quality of care and survival in patients diagnosed with colorectal cancer (CRC).

Methods
3999 CRC patients diagnosed between 2005 and 2014 in the area covered by the “Calvados Registry of Digestive Tumours” were included. Multivariate multinomial logistic regression was used to assess the factors associated with presentation in MDTMs. Univariate analyses were performed to study the impact of MDTMs on quality of care. Multivariate Cox model and the Log-Rank test were used to assess the impact of MDTMs on survival.

Results
Non-presentation or unknown presentation in MDTMs were associated with higher age at diagnosis, dying within 3 months after diagnosis, unknown metastatic status, non-metastatic cancer and colon cancer. Non-presentation was associated with a diagnosis after 2010. Unknown presentation was associated with a diagnosis before 2007 and a longer travel time to the reference care centres. Presentation in MDTMs was associated with more chemotherapy administration for patients with metastatic cancer and more adjuvant chemotherapy for patients with stage III colon cancer. After excluding poor prognosis patients, lower survival was significantly associated with higher age at diagnosis, unknown metastatic status or metastatic cancer, presence of comorbidities, rectal cancer and non-presentation in MDTMs (HR = 1.5 [1.1–2.0], p < 0.001).

Conclusions
Elderly and poor prognosis patients were less presented in MDTMs. Geriatric assessments before presentation in MDTMs were shown to improve care plan establishment. The 100% objective is not coherent if MDTMs are only to discuss diagnosis and curative cares. They could also be a place to discuss therapeutic limitations. MDTMs were associated with better treatment and longer survival. We must ensure that there is no inequity in presentation in MDTMs that could lead to a loss of chance for patients.
Feasibility of implementing recommendations to improve neglected tropical diseases surveillance and response in Kenya: a modified Delphi study

Published: October 2021

Abstract
Background
Effective health information systems (HIS) are critical towards achieving timely response to preventive chemotherapy neglected tropical diseases (PC-NTDs) and their eventual elimination. Strengthened HIS enable prompt case detection and effective response to halt disease transmission and prevent probable outbreaks. This study aimed to assess the importance and feasibility of implementing recommendations for improving surveillance core functions, support functions and surveillance attributes concerning PC-NTDs in Kenya.

Methods
A descriptive web-based Delphi process comprising of two survey rounds was used to achieve group consensus on the importance of recommended actions and feasibility of their implementation. In the first round, participants were enrolled to complete a five-point likert-type self-administered electronic questionnaire comprising of 60 statements across 12 sub-domains on the importance of recommendations. In the second round, participants reappraised their responses following completion of a questionnaire with 56 rephrased statements on feasibility of implementing the recommendations to improve PC-NTDs surveillance and response. Data from both rounds were analysed using descriptive statistics and thematic analysis performed for the open-ended responses.

Results
Sixty-two key stakeholders actively involved in surveillance and response activities in seven PC-NTDs endemic counties in Kenya were invited to participate. Of these, 50/62 completed the first round (81 % response rate) and 45/50 completed the second round (90 % response rate). Consensus was achieved (defined as > 70 % agreement) on the importance (93 %) of recommendation statements and feasibility (82 %) of implementing the important recommendations. Stakeholders agreed on the importance and feasibility of specific recommendations across the 12 sub-domains: case detection and registration, reporting, data analysis, feedback, epidemic preparedness and response, supervision, training, resources, simplicity, acceptability, stability and flexibility. However, there was lack of consensus on the feasibility of conducting routine data analysis, increasing supervision of surveillance activities at lower levels and retaining trained surveillance staff across all levels.

Conclusions
Consensus among health stakeholders on implementation of the important and feasible recommendations will inform relevant strategies for strengthening specific surveillance system functions in view of PC-NTDs in Kenya.

Abstract
Background
With the identification of new targetable drivers and the recent emergence of novel targeted drugs, using comprehensive genomic profiling in lieu of the routine testing for classic drivers in the clinical care for advanced NSCLC has been increasingly advocated. However, the key assumption justifying this practice, that comprehensive genomic profiling could lead to effective anticancer therapies and improve patient outcomes, remains unproved.

Methods
Comprehensive genomic profiling was prospectively applied in 1564 advanced NSCLC patients to identify potentially actionable genomic alterations. Patients were assigned to genotype-matched targeted therapies or nonmatched therapies based on the profiling results. Its utility in directing treatments was determined by the proportion of patients receiving genotype-matched targeted therapies and the proportion of patients being enrolled into genotype-matched clinical trials. Its impacts on patient outcomes were assessed by comparing progression-free survival (PFS) and overall survival (OS) between patients who received a genotype-matched and nonmatched therapy.

Results
From October 2016 to October 2019, tumor genomic profiles were established in 1166 patients, leading to a matched targeted therapy in 37.7% (n = 440) and a genotype-matched trial enrollment in 20.9% of patients (n = 244). Potentially actionable alterations were detected in 781 patients (67.0%). For these patients, a genomic profiling-directed matched therapy significantly improved PFS (9.0 months vs 4.9 months, P < 0.001) and OS (3.9 years vs 2.5 years, P < 0.001) compared with a nonmatched therapy. Excluding patients with standard targeted therapies, genomic profiling led to a matched targeted therapy in 16.7% (n = 24) and a matched trial enrollment in 11.2% (n = 16) of patients. No PFS (4.7 months vs 4.6 months, P = 0.530) or OS (1.9 years vs 2.4 years, P = 0.238) benefit was observed with the use of genotype-matched targeted therapies in this population.

Conclusions
Comprehensive genomic profiling is of clinical utility in assisting treatment selection, facilitating clinical trial enrollment, and improving patient outcomes in advanced NSCLC. However, for patients carrying alterations without standard-of-care targeted drugs, the interpretation of genomic profiling results should be careful given the low likelihood of benefit from the investigational or off-label use of targeted therapies in this population in the current treatment landscape.

A magneto-optical biochip for rapid assay based on the Cotton–Mouton effect of γ-Fe2O3@Au core/shell nanoparticles
Authors: Chen Kuen-Lin , Yang Zih-Yan , Lin Chin-Wei 
Published: October 2021

Abstract
Background
In the past decades, different diseases and viruses, such as Ebola, MERS and COVID-19, impacted the human society and caused huge cost in different fields. With the increasing threat from the new or unknown diseases, the demand of rapid and sensitive assay method is more and more urgent.

Results
In this work, we developed a magneto-optical biochip based on the Cotton–Mouton effect of γ-Fe2O3@Au core/shell magnetic nanoparticles. We performed a proof-of-concept experiment for the detection of the spike glycoprotein S of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The assay was achieved by measuring the magneto-optical Cotton–Mouton effect of the biochip. This magneto-optical biochip can not only be used to detect SARS-CoV-2 but also can be easily modified for other diseases assay.

Conclusion
The assay process is simple and the whole testing time takes only 50 min including 3 min for the CM rotation measurement. The detection limit of our method for the spike glycoprotein S of SARS-CoV-2 is estimated as low as 0.27 ng/mL (3.4 pM).

Abstract
Background
The current pandemic of COVID-19 impacted the psychological wellbeing of populations globally.

Objectives
We aimed to examine the extent and identify factors associated with psychological distress, fear of COVID-19 and coping.

Methods
We conducted a cross-sectional study across 17 countries during Jun-2020 to Jan-2021. Levels of psychological distress (Kessler Psychological Distress Scale), fear of COVID-19 (Fear of COVID-19 Scale), and coping (Brief Resilient Coping Scale) were assessed.

Results
A total of 8,559 people participated; mean age (±SD) was 33(±13) years, 64% were females and 40% self-identified as frontline workers. More than two-thirds (69%) experienced moderate-to-very high levels of psychological distress, which was 46% in Thailand and 91% in Egypt. A quarter (24%) had high levels of fear of COVID-19, which was as low as 9% in Libya and as high as 38% in Bangladesh. More than half (57%) exhibited medium to high resilient coping; the lowest prevalence (3%) was reported in Australia and the highest (72%) in Syria. Being female (AOR 1.31 [95% CIs 1.09-1.57]), perceived distress due to change of employment status (1.56 [1.29-1.90]), comorbidity with mental health conditions (3.02 [1.20-7.60]) were associated with higher levels of psychological distress and fear. Doctors had higher psychological distress (1.43 [1.04-1.97]), but low levels of fear of COVID-19 (0.55 [0.41-0.76]); nurses had medium to high resilient coping (1.30 [1.03-1.65]).

Conclusions
The extent of psychological distress, fear of COVID-19 and coping varied by country; however, we identified few higher risk groups who were more vulnerable than others. There is an urgent need to prioritise health and well-being of those people through well-designed intervention that may need to be tailored to meet country specific requirements.

Published: October 2021

Abstract
Background
With the increasing digitalization of the working environment, the demands on managers are changing fundamentally to the point of an emerging field of research in digital leadership. Municipal administrations are particularly affected by the digital transformation processes. Therefore, a score to measure the construct of digital leadership competence in the context of virtual-based workstation was developed and tested.

Methods
Based on an online survey with n = 546 employees at virtual-based workstations in municipal administrations in 2020, the instrument is tested regarding selectivity (coefficients), dimensionality (principal component analysis), homogeneity (inter-product-moment correlations), reliability (Cronbach’s α) and construct validity (correlation with general leadership skills).

Results
The instrument can be considered selective, one-dimensional, homogeneous, reliable and constructively valid in the sense of the formulated hypotheses. By integrating the employees’ perspective, the instrument aims to be one of the first of its kind to initiate a scientific further discourse. Among other things, the categorization of the co-determination component as either traditional or digital leadership can be discussed.

Conclusions
The developed instrument for measuring digital leadership performs well concerning the aspects of discriminatory power, one-dimensionality, homogeneity, reliability as well as construct validity. It aims to induce further research and a scientific discourse on the topic of health-oriented leadership within the world of work 4.0.

Abstract
Background
Thyroid dysfunction can affect fertility and miscarriage risk by affecting the process of follicular growth, embryo development, implantation, and placental formation. It has been suggested that thyroid disorders are associated with ovarian reserve by affecting the follicular process. The aim of the present study was to investigate the relationship between thyroid hormone levels and ovarian reserve.

Methods
Three hundred fourteen women with infertility due to various etiologies were enrolled in this study (172 individuals with Anti-Mullerian hormone (AMH) level ≥ 1.1 ng/ml and 142 individuals with AMH < 1.1 ng/ml). Serum levels of follicle-stimulating hormone (FSH), estradiol (E2) on day 2–4 of menstrual cycles, AMH, Thyroid-stimulating hormone (TSH), and thyroxine (free T4) were evaluated.

Results
In participants with age over 35 years, median TSH level in women with AMH < 1.1 ng/ml was significantly higher than those with AMH ≥1.1 ng/ml (P-value =0.037). There was no significant difference in body mass index (BMI) in patients with age older than 35 years and younger than 35 years sub-groups based on AMH level (P-value = 0.102, and P-value = 0.909 respectively). With one unit increase in TSH level, the odds of having AMH < 1.1 ng/ml increases by 1.25 times or by 25% (P-value =0.017). Receiver operator characteristic (ROC) curve analysis showed a TSH cut-off point of 1.465 mIU/L in participants over 35 years in identifying decreased AMH level.

Conclusion
Our study supports the relationship between TSH level and ovarian reserve so that with an increase in TSH from a certain level is associated with a decrease in ovarian function.
