Abstract
Background
General practitioners (GPs) play a crucial role in the provision of end-of-life care (EoLC). The present study aimed at comparing the quality of GPs’ EoLC before and after an intervention involving a clinical decision aid and a public campaign.

Methods
The study was part of the larger interventional study ‘Optimal care at the end of life’ (OPAL) (Innovation Fund, Grant No. 01VSF17028). The intervention lasted 12 months and comprised two components: (1) implementation of the Supportive and Palliative Care Indicators Tool (SPICT-DE™) in general practice and (2) a public campaign in two German counties to inform and connect regional health care providers and stakeholders in EoLC. Participating GPs completed the General Practice End of Life Care Index (GP-EoLC-I) pre- (t0) and post- (t1) intervention. The GP-EoLC-I (25 items, score range: 14–40) is a self-assessment questionnaire that measures the quality of GPs’ EoLC. It includes two subscales: practice organisation and clinical practice. Data were analysed descriptively, and a paired t-test was applied for the pre–post comparison.

Results
Forty-five GPs (female: 29%, median age: 57 years) from 33 general practices participated in the intervention and took part in the survey at both times of measurement (t0 and t1). The mean GP-EoLC-I score (t0 = 27.9; t1 = 29.8) increased significantly by 1.9 points between t0 and t1 (t(44) = − 3.0; p = 0.005). Scores on the practice organisation subscale (t0 = 6.9; t1 = 7.6) remained almost similar (t(44) = -2.0; p = 0.057), whereas those of the clinical practice subscale (t0 = 21.0; t1 = 22.2) changed significantly between t0 and t1 (t(44) = -2.6; p = 0.011). In particular, items regarding the record of care plans, patients’ preferred place of care at the end of life and patients’ preferred place of death, as well as the routine documentation of impending death, changed positively.

Conclusions
GPs’ self-assessed quality of EoLC seemed to improve after a regional intervention that involved both the implementation of the SPICT-DE™ in daily practice and a public campaign. In particular, improvement related to the domains of care planning and documentation.

AbstractBackgroundDelayed bleeding is an important adverse event after gastric endoscopic submucosal dissection (ESD). We aimed to externally validate the Bleeding after ESD Trend from Japan (BEST-J) score and subsequently develop a risk prediction model for bleeding in Chinese patients with early gastric cancer (EGC) after ESD.MethodsThe clinical data of patients who underwent ESD for EGC in Beijing Friendship Hospital from June 2013 to December 2019 were collected retrospectively. The BEST-J score was evaluated according to the clinical data. Through univariate and multivariate logistic regression analyses of the clinical data, the factors affecting delayed bleeding were identified, and a new risk prediction model for bleeding was established. Receiver operating characteristic (ROC) curves were used to evaluate the predictive value of the two prediction models.ResultsA total of 444 patients with EGC undergoing ESD were included, of whom 27 patients had delayed bleeding (6.1%). Multivariate logistic regression analysis showed that a history of smoking (P = 0.029), tumor size > 20 mm (P = 0.022), intraoperative use of hemoclips (P = 0.025), resection of multiple tumors (P = 0.027), and prolongation of activated partial thromboplastin time (APTT) (P = 0.020) were independent influencing factors for delayed bleeding. ROC curve analysis showed that the areas under the curves (AUCs) were different between the BEST-J score and the newly built prediction model (0.624 vs. 0.749, P = 0.012).ConclusionsThe BEST-J score has moderately good discrimination for Chinese patients with EGC. However, for patients with EGC without severe comorbidities, the new risk prediction model may predict delayed bleeding better than the BEST-J score.

Abstract
Background
Our previous study demonstrated the safety and effectiveness of abdominal radical trachelectomy during pregnancy but did not focus on the fetus. This study aimed to clarify the influence of abdominal radical trachelectomy performed during pregnancy on the fetus.

Methods
Eight cervical cancer patients who underwent abdominal radical trachelectomy at our hospital between February 2013 and August 2020 were enrolled in this study. To assess the peri- and postoperative influence on the fetus, we performed fetal heart monitoring at 30-min intervals during abdominal radical trachelectomy and calculated the estimated fetal body weight and resistance indexes of the middle cerebral artery and umbilical artery from postsurgery until delivery.

Results
Four out of eight patients had preterm birth due to chorioamnionitis in one case and consideration of the recurrent risk of cervical cancer in three cases. Fetal heart monitoring during abdominal radical trachelectomy revealed deceleration just once in one case but no abnormal findings in the other cases. In all cases, the fetal growth after abdominal radical trachelectomy was normal until delivery. No abnormal Doppler findings were detected in the middle cerebral artery or umbilical artery.

Conclusion
Our findings clarified that abdominal radical trachelectomy performed for the treatment of early-stage cervical cancer during pregnancy has no obvious influence on fetal growth. Next, it is necessary to evaluate the growth and development of children delivered from mothers who have undergone abdominal radical trachelectomy during pregnancy.
Prognostic impact of angiotensin-converting enzyme inhibitors and angiotensin receptors blockers in esophageal or gastric cancer patients with hypertension - a real-world study
Authors: Li Po-Chih , Huang Ru-Yu , Yang Yu-Chien , Hsieh Kun-Pin , Yang Yi-Hsin 
Published: April 2022

Abstract
Background
Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are used in treating cardiovascular diseases. Previous studies indicated that ACEIs/ARBs may benefit cancer patients by inhibiting tumor angiogenesis and proliferation. The effect of ACEIs/ARBs on cancer survival in esophageal and gastric cancer is still unclear. This study is to investigate the association between ACEIs/ARBs usage and esophageal and gastric cancer prognosis.

Methods
This retrospective cohort study identified esophageal and gastric cancer patients during 2008–2016 from the Taiwan Cancer Registry, and obtained medication usage and follow-up information from the National Health Insurance Research Database and Death Registry. Analysis groups were defined as ACEIs/ARBs user or non-user based on the usage of ACEIs/ARBs within the 6 months after cancer diagnosis. The stabilized inverse probability of treatment weighting using propensity scores was applied to balance covariates between study groups. We also used Kaplan-Meier estimates and Cox regression to compare survival outcome and estimate hazard ratios (HRs).

Results
We identified 14,463 and 21,483 newly-diagnosed esophageal and gastric cancer patients during 2008–2016. ACEIs/ARBs users were associated with lower risk of cancer-specific mortality, although only significantly in gastric cancer (gastric: adjusted HR = 0.87, 95% CI = 0.78–0.97; esophageal: adjusted HR =0.88, 95% CI = 0.76–1.02). A better survival outcome was observed among patients who received higher cumulative defined daily dose of ACEIs/ARBs.

Conclusions
We found that using ACEIs/ARBs after cancer diagnosis were associated with lower risk of mortality. Our results add to the knowledge of the benefit of ACEIs/ARBs against mortality in individuals with esophageal/gastric cancer patients with hypertension.

Published: April 2022

Abstract
Background
Hirschsprung disease (HSCR) is a complex genetic disorder characterized by the lack of ganglion cells in the intestines. A current study showed that the NRG1 rare variant frequency in Indonesian patients with HSCR is only 0.9%. Here, we investigated the impact of NRG1 expressions and methylation patterns on the pathogenesis of HSCR.

Methods
This cross-sectional study determined NRG1 type I (HRGα, HRGβ1, HRGβ2, HRGβ3, HRGγ, and NDF43 isoforms), type II and type III expressions in both ganglionic and aganglionic colons of 20 patients with HSCR and 10 control colons by real-time polymerase chain reaction (qPCR). For methylation studies, we treated the extracted gDNA from 16 HSCR patients’ and 17 control colons with sodium bisulfate and analyzed the methylation pattern of NRG1 exon 1 with methylation-specific PCR. The samples were collected and analyzed at our institution from December 2018 to December 2020.

Results
NRG1 types I, II and III expressions were upregulated (17.2-, 3.2-, and 7.2-fold, respectively) in the ganglionic colons compared with control colons (type I: 13.32 ± 1.65 vs. 17.42 ± 1.51, p < 0.01; type II: 13.73 ± 2.02 vs. 16.29 ± 2.19, p < 0.01; type III: 13.47 ± 3.01 vs. 16.32 ± 2.58, p = 0.03; respectively); while only type I (7.7-fold) and HRGβ1/HRGβ2 (3.3-fold) isoforms were significantly upregulated in the aganglionic colons compared to the controls (type I: 14.47 ± 1.66 vs. 17.42 ± 1.51, p < 0.01; HRGβ1/HRGβ2: 13.62 ± 3.42 vs 14.75 ± 1.26, p = 0.01). Moreover, the frequency of partially methylated NRG1 was higher in the ganglionic (81%) and aganglionic (75%) colons than in the controls (59%).

Conclusions
Our study provides further insights into the aberrant NRG1 expression in the colons of patients with HSCR, both ganglionic and aganglionic bowel, which might contribute to the development of HSCR, particularly in Indonesia. Furthermore, these aberrant NRG1 expressions might be associated with its methylation pattern.

Abstract
Objective
The objective of the study is to explore the long-term effectiveness and tolerability of metoclopramide in the treatment of CIH.

Method
This study is a retrospective, observational cohort study of patients prescribed metoclopramide for CIH at the South London & Maudsley (SLaM) NHS Foundation Trust.

Results
Of the 96 patients identified, 14 patients were eligible for inclusion in our study. Five patients continued treatment with a mean duration of 27 months (SD = 17.8), and one patient continued until transfer with a duration of 3 months. Eight patients discontinued treatment after a mean duration of 8 months.

Conclusion
Metoclopramide may be an effective and tolerated drug in CIH, but more data is required to establish its place in the pharmacotherapy of this condition.

Published: April 2022

Abstract
Background
The economic burden of interstitial lung disease (ILD) is unknown, limiting informed resource allocation and planning. We sought to conduct the first systematic review on the direct, indirect, and overall costs associated with ILD and to evaluate the cost-effectiveness of current therapies globally.

Methods
We conducted systematic reviews of ILD disease cost studies and cost-effectiveness analyses (CEAs) using MEDLINE, Embase, and Web of Science databases between 2000 and 2020. We compared ILD costs between countries according to the share of costs towards each country’s respective gross domestic product (GDP) per capita. Costs are reported in 2020 USD.

Results
We identified 25 disease cost studies and 7 CEAs. The direct medical costs ranged between $1824 and $116,927 annually per patient (median $32,834; 14–180% of GDP per capita in Western countries). The leading drivers of direct costs were inpatient (55%), outpatient (22%), and medication costs (18%), based on pooled estimates. Annual indirect costs ranged from $7149 to $10,902 per employed patient (median $9607; 12–23% of GDP per capita). Among the 7 CEAs, only 1 study (14%) showed an ILD therapy (ambulatory oxygen) was cost-effective compared to best supportive care.

Conclusion
The direct and indirect costs associated with ILD are consistently high in all countries with available data, with cost-effectiveness profiles of new therapies generally undesirable. Globally, the median total direct cost for ILD equates to 51% of a country’s GDP per capita and has been increasing over time.
Suppression of MIR31HG affects the functional properties of thyroid cancer cells depending on the miR-761/MAPK1 axis
Authors: Peng Shuwang , Chen Luyang , Yuan Zhengtai , Duan Shanshan 
Published: April 2022

Abstract
Background
Thyroid cancer is the most prevalent endocrine malignancy. Long non-coding RNA (lncRNA) MIR31HG is abnormally expressed in thyroid cancer tissues. However, the precise, critical role of MIR31HG in thyroid cancer development remains unclear.

Methods
MIR31HG, microRNA (miR)-761 and mitogen-activated protein kinase 1 (MAPK1) were quantified by quantitative real-time PCR (qRT-PCR) and immunoblotting. Cell viability, proliferation, apoptosis, invasion and migration abilities were evaluated by MTS, 5-Ethynyl-2′-Deoxyuridine (EdU), flow cytometry, transwell and wound-healing assays, respectively. Dual-luciferase reporter assays were used to validate the direct relationship between miR-761 and MIR31HG or MAPK1.

Results
MIR31HG was overexpressed in human thyroid cancer, and its overexpression predicted poor prognosis. Suppression of MIR31HG impeded cell proliferation, invasion and migration, as well as promoted cell apoptosis in vitro, and diminished the growth of xenograft tumors in vivo. Mechanistically, MIR31HG targeted and regulated miR-761. Moreover, miR-761 was identified as a molecular mediator of MIR30HG function in regulating thyroid cancer cell behaviors. MAPK1 was established as a direct and functional target of miR-761 and MAPK1 knockdown phenocopied miR-761 overexpression in impacting thyroid cancer cell behaviors. Furthermore, MIR31HG modulated MAPK1 expression by competitively binding to miR-761 via the shared binding sequence.

Conclusion
Our findings demonstrate that MIR31HG targets miR-761 to regulate the functional behaviors of thyroid cancer cells by upregulating MAPK1, highlighting a strong rationale for developing MIR31HG as a novel therapeutic target against thyroid cancer.
Palliative Care education in Armenia: perspectives of first-year Armenian physician residents
Authors: Hagedorn Carolin , Tadevosyan Artashes , Mason Stephen , Elsner Frank 
Published: April 2022

Abstract
Background
Due to developing demographic changes, including an aging society and the increasing prevalence of non-communicable diseases, Palliative Care is increasingly highlighted as a universal healthcare need. The need for Palliative Care in Armenia is set against the context of an underdeveloped healthcare system. Further, the absence of palliative medicine within medical education, particularly undergraduate education in Armenia presents a major barrier to improving care. This research aimed to assess the perception of young Armenian physicians’ understanding of Palliative Care, its perceived status in Armenia and the experience and influence of any engaged Palliative Care education.

Methods
Twenty Armenian first-year residents with different specializations were interviewed July and September 2016 regarding: understanding/knowledge, experiences, perceived competence, and expectations of Palliative Care and Palliative Care education. The transcripts from these semi-structured interviews were analyzed using Qualitative Content Analysis.

Results
Participants perceived that Armenia’s health care system lacked sufficient Palliative Care and Palliative Care education. Although elements of Palliative Care were included in different specialty teaching, this provided just a partial understanding of typical Palliative Care patients/symptoms, approaches to holistic care, and crucially key communication skills. Challenges noted by participants in caring for Palliative Care patients included emotional difficulties, communication of diagnosis/prognosis, uninformed patients and concerns for patients, families, and physicians. Self-confidence in caring for patients with incurable illness varied. Participants hoped for increasing availability and accessibility of Palliative Care, and extension of clinical education in Palliative Care at all levels (undergraduate, postgraduate, specialization).

Conclusions
Absence of training has resulted in misconceptions and ignorance of common concepts and practices in Palliative Care. Palliative Care education needs to be systematically developed and integrated into clinical training within Armenia. This research may provide a rallying call for changes within the core curricula in Armenia and may also encourage collaborative development in associated countries of the Caucasus region.

Abstract
Background
The usage of smartphones in the daily clinical routine is an essential aspect however it seems that they also present an important distractor that needs to be evaluated. The aim of this prospective study was the evaluation of the influence of phone calls as distractors on the performance levels of medical students during an objective structured clinical examination (OSCE), simulating the normal clinical practice.

Methods
As the goal of an OSCE presents the examination of clinical skills of medical students in a realistic setting, more than 100 students recruited from the university hospital of Cologne participated in either OSCE I or II. During the OSCE I intravenous cannulation was simulated while OSCE II simulated an acute abdominal pain station. Participants had to perform each of these stations under two circumstances: a normal simulated OSCE and an OSCE station with phone call distraction. Their performance during both simulations was then evaluated.

Results
In OSCE I students achieved significantly more points in the intravenous cannulation station if they were not distracted by phone calls (M=6.44 vs M=5.95). In OSCE II students achieved significantly more points in the acute abdominal pain station if they were not distracted by phone calls (M=7.59 vs M=6.84). While comparing only those students that completed both stations in OSCE I/II participating students achieved significantly more points in both OSCE I and II if they were not distracted by phone calls.

Conclusion
The presented data shows that phone call distraction decreases the performance level of medical students during an OSCE station. Therefore, it is an indicator that distraction especially for younger doctors should be held to a minimum. On a second note distraction should be integrated in the medical education system as it plays an important role in clinical routine.

Abstract
Background
Simulation-Based Medical Education (SBME) is a teaching method commonly used in undergraduate medical education. Although Thai medical schools have developed a system that incorporates SBME, various aspects of that system require improvement. We surveyed medical school administrators, instructors, and students about SBME in their institutions and the obstacles involved in its implementation, as well as their experiences, expectations, and attitudes regarding the current system.

Methods
We conducted a cross-sectional online survey between August 2019 and July 2020 among administrators, instructors, and 6th-year medical students. A structured questionnaire was developed and distributed to volunteers as an online survey. We recorded details about the SBME system as well as participant characteristics, obstacles, experiences, expectations, and attitudes. We used descriptive statistics as appropriate.

Results
We received responses from 15 (68.2%) administrators, 186 instructors, and 371 (13.7%) sixth-year medical students. SBME was commonly used in teaching and evaluation but less so in research. It was mainly used to improve psychomotor tasks, knowledge, patient care, and communication skills. The expected outcomes were improvements in students’ performance, knowledge, and practice. The clinical courses were longer and had fewer participants than the pre-clinical courses. Obstacles encountered included shortages of faculty and simulators, time and space limitations, inadequate faculty training, and insufficient financial support. The administrators surveyed had positive attitudes toward SBME. Medical students reported having experience with SBME and strongly agreed that it was beneficial; however, they expected fewer students per class and more learning time to be devoted to these methods.

Conclusions
SBME in Thailand is focused on teaching and assessment. The system could be improved through better-trained faculty, greater available space, more simulators, and sufficient funding. There were also some aspects that failed to meet students’ expectations and need to be addressed. However, participants expressed positive attitudes toward SBME.
