Abstract
Background
Objective Structured Clinical Examinations (OSCEs) are a common form of assessment used across medical schools in the UK to assess clinical competence and practical skills and are traditionally held in an in-person format. In the past, medical students have often prepared for such exams through in-person peer-assisted learning (PAL), however, due to the recent Covid-19 pandemic, many in-person teaching sessions transitioned to online-based formats. There is currently a paucity of research on the utility of virtual PAL OSCE sessions and thus, we carried out a national pilot study to determine the feasibility of virtual OSCE teaching via feedback from participants and examiners.

Methods
A total of 85 students from 19 UK-based medical schools with eight students based internationally attended the series of online OSCE workshops delivered via Zoom®. All students and examiners completed a feedback questionnaire at the end of each session regarding parameters, which included questions on pre-and post-workshop confidence in three OSCE domains: history-taking, communication and data interpretation. A Likert scale using 5 Likert items was used to self-report confidence, and the results were analysed using the Mann-Whitney U test after assessing for normality using the Shapiro-Wilk test.

Results
Results from student feedback showed an increase in confidence for all three OSCE domains after each event (p < 0.001) with 69.4% agreeing or strongly agreeing that online OSCE sessions could sufficiently prepare them for in-person exams. Questionnaire feedback revealed that 97.6% of students and 86.7% of examiners agreed that virtual OSCE teaching would be useful for preparing for in-person OSCE examinations after the pandemic.

Conclusion
Most participants in the virtual OSCE sessions reported an improvement in their confidence in history-taking, communication and data interpretation skills. Of the participants and examiners that had also experienced in-person OSCE examinations, the majority also reported that they found virtual OSCE sessions to be as engaging and as interactive as in-person teaching. This study has demonstrated that virtual OSCE workshops are a feasible option with the potential to be beneficial beyond the pandemic. However, more studies are required to assess the overall impact on student learning and to determine the value of virtual OSCE workshops on exam performance.
Respecting, protecting and fulfilling the human right to health
Authors: Nampewo Zahara , Mike Jennifer Heaven , Wolff Jonathan 
Published: March 2022

Abstract
Background
Human rights are best protected, promoted and guaranteed when they can compel binding and enforceability duty. One prominent criticism of category of human rights which includes the human right to health is that it is difficult, to assign the duties that correspond to these rights, because of stark disparity in how the main duty bearers approach their duties.

Methods
This paper adopts a doctrinal approach to examine and evaluate the duties to the right to health. The method in this study entails a detailed literature search to systematically evaluate the legal implications, regulations, arguments and policy regarding the nature of the obligation to the right to health. This study also engages with normative and philosophical aspects of human rights.

Results
This paper posits that human rights protect against common, serious, and remediable threats and risks, and ensure that there are remedies from governments and third parties. However, it is difficult to compel duties especially in regard to the right to health. First it is not easy to achieve a uniform standard for duty bearers implied by the words ‘highest attainable physical and mental health.’ Theorists discussed in the paper outline views of what this could mean, from serious to common health concerns. Second, the right to health is not a legally established right in many jurisdictions, making it difficult to enforce. This paper outlines different layers of state and non-state legal duty bearers to enforce the right to health.

Conclusion
The duty to respect, protect, fulfil and even remedy the right to health, will often be meaningless in practice without a clear identification of the necessary duty bearers to enforce them. The law is the starting point for this to not only enshrine this right as a legally enforceable one but also to clearly identify duty bearers. Without this, the human right to health as outlined under international and regional human rights law generates an implausible, or even impossible, profusion of duties. There remains much work still to be done especially on the moral and legal fronts in order to fully guarantee this right.

Clear cell carcinoma arising from abdominal wall endometriosis—a report on two cases and literature review
Authors: Bahall Vishal , De Barry Lance , Rampersad Arlene 
Published: March 2022

Abstract
Background
Malignant transformation of abdominal wall endometriosis is extremely rare. Clear cell carcinoma and endometrioid carcinoma are the two most prevalent histological subtypes of malignant endometriosis. To date, approximately, thirty cases of clear cell carcinoma arising from abdominal wall endometriosis have been described worldwide.

Case presentation
We report two cases of clear cell carcinoma developing postoperatively in the anterior abdominal wall in women with a history of extensive endometriosis. Histopathology of the resected abdominal wall tumor demonstrated benign endometriosis contiguous with features of clear cell carcinoma. These histological features satisfied Sampson’s criteria which are required for diagnosing malignant endometriosis. Both patients were successfully managed with platinum-based adjuvant chemotherapy following cytoreductive surgery.

Conclusion
Clear cell carcinoma arising from the abdominal wall endometriosis is a rare, highly aggressive cancer with a propensity to recur or metastasize. Due to the limited publications on this clinical entity, there are no clearly established protocols regarding adjuvant treatment, and an evaluation of prognostic factors is lacking. Clinicians must have a high index of suspicion for malignant endometriosis of the abdominal wall, particularly in patients with an abdominal wall mass, prior abdominal surgery, and long-standing endometriosis. By presenting our case, we expect to raise awareness and study of this rare endometriosis-related neoplasm.
CYP1B1-catalyzed 4-OHE2 promotes the castration resistance of prostate cancer stem cells by estrogen receptor α-mediated IL6 activation

Published: March 2022

Abstract
Background
Resistance to androgen deprivation therapy remains a major challenge for the clinical treatment of patients with castration-resistant prostate cancer (CRPC). CYP1B1, a critical enzyme that catalyzes the conversion of estradiol to 4-Hydroxy-17β-estradiol (4-OHE2), has been reported to promote the development and progression of hormone-related cancer, but its role in CRPC is unclear.

Methods
To explore the underlying mechanism which CYP1B1 promotes the prostate cancer stem cells (PCSCs) characteristics, bioinformatics analyses of human clinical prostate cancer (PCa) datasets were performed. CYP1B1, IL6, and estrogen receptor-α (ERα) expression levels were evaluated in PCa and CRPC tissues via immunohistochemistry. The high-performance liquid chromatography-mass spectrometry assay was carried out to examine intracellular 4-OHE2 levels. Serum-free suspension culture and flow cytometry assays were performed to evaluate PCSCs. Chromatin immunoprecipitation was used to validate that 4-OHE2 recruited ERα to the IL6 promoter.

Results
CYP1B1 expression was significantly increased in CRPC tissues and androgen-independent PCa cell lines. CYP1B1+ PCa cells were significantly enriched in bicalutamide-treated LNCaP cells, and CYP1B1 knockdown reduced the cell viability under bicalutamide treatment. In addition, CYP1B1 knockdown decreased the intracellular 4-OHE2 concentration, accompanied by reduced PCSC characteristics. In PCa cells, 4-OHE2 stimulated ERα transcriptional activity and upregulated the expression of IL6 and downstream genes of the IL6-STAT3 signaling. 4-OHE2 increased cell viability under bicalutamide treatment and promoted PCSC characteristics, while IL6 neutralizing antibody reversed these effects. Mechanistically, siERα and the ER antagonist ICI182780 significantly attenuated 4-OHE2-induced IL6 expression, and 4-OHE2 promoted the binding of ERα to the estrogen response element of the IL6 promoter.

Conclusions
Our findings indicate that CYP1B1-catalyzed 4-OHE2 enhanced PCSC characteristics and attenuated bicalutamide sensitivity by ERα-mediated the IL6-STAT3 pathway activation. Our study further emphasizes the role of CYP1B1 in castration resistance and illustrates a novel mechanism of CRPC development.

Abstract
Background
Integrated patterns of energy balance-related behaviours of preschool children in Asia are sparse, with few comparative analyses.

Purpose
Using cohorts in Singapore (GUSTO) and France (EDEN), we characterized lifestyle patterns of children and investigated their associations with family-focused contextual factors.

Methods
Ten behavioural variables related to child’s diet, walking, outdoor play and screen time were ascertained by parental questionnaires at age 5–6 years. Using principal component analysis, sex-specific lifestyle patterns were derived independently for 630 GUSTO and 989 EDEN children. Contextual variables were organised into distal (family socio-economics, demographics), intermediate (parental health, lifestyle habits) and proximal (parent-child interaction factors) levels of influence and analysed with hierarchical linear regression.

Results
Three broadly similar lifestyle patterns were identified in both cohorts: “discretionary consumption and high screen time”, “fruit, vegetables, and low screen time” and “high outdoor playtime and walking”. The latter two patterns showed small differences between cohorts and sexes. The “discretionary consumption and high screen time” pattern was consistently similar in both cohorts; distal associated factors were lower maternal education (EDEN boys), no younger siblings (GUSTO boys) and Malay/Indian ethnicity (GUSTO), while intermediate and proximal associated factors in both cohorts and sexes were poor maternal diets during pregnancy, parents allowing high child control over food intake, snacking between meals and having television on while eating.

Conclusions
Three similar lifestyle patterns were observed among preschool children in Singapore and France. There were more common associated proximal factors than distal ones. Cohort specific family-focused contextual factors likely reflect differences in social and cultural settings. Findings will aid development of strategies to improve child health.

Published: March 2022

AbstractOverground powered lower limb exoskeletons (EXOs) have proven to be valid devices in gait rehabilitation in individuals with spinal cord injury (SCI). Although several articles have reported the effects of EXOs in these individuals, the few reviews available focused on specific domains, mainly walking. The aim of this systematic review is to provide a general overview of the effects of commercial EXOs (i.e. not EXOs used in military and industry applications) for medical purposes in individuals with SCI. This systematic review was conducted following the PRISMA guidelines and it referred to MED-LINE, EMBASE, SCOPUS, Web of Science and Cochrane library databases. The studies included were Randomized Clinical Trials (RCTs) and non-RCT based on EXOs intervention on individuals with SCI. Out of 1296 studies screened, 41 met inclusion criteria. Among all the EXO studies, the Ekso device was the most discussed, followed by ReWalk, Indego, HAL and Rex devices. Since 14 different domains were considered, the outcome measures were heterogeneous. The most investigated domain was walking, followed by cardiorespiratory/metabolic responses, spasticity, balance, quality of life, human–robot interaction, robot data, bowel functionality, strength, daily living activity, neurophysiology, sensory function, bladder functionality and body composition/bone density domains. There were no reports of negative effects due to EXOs trainings and most of the significant positive effects were noted in the walking domain for Ekso, ReWalk, HAL and Indego devices. Ekso studies reported significant effects due to training in almost all domains, while this was not the case with the Rex device. Not a single study carried out on sensory functions or bladder functionality reached significance for any EXO. It is not possible to draw general conclusions about the effects of EXOs usage due to the lack of high-quality studies as addressed by the Downs and Black tool, the heterogeneity of the outcome measures, of the protocols and of the SCI epidemiological/neurological features. However, the strengths and weaknesses of EXOs are starting to be defined, even considering the different types of adverse events that EXO training brought about. EXO training showed to bring significant improvements over time, but whether its effectiveness is greater or less than conventional therapy or other treatments is still mostly unknown. High-quality RCTs are necessary to better define the pros and cons of the EXOs available today. Studies of this kind could help clinicians to better choose the appropriate training for individuals with SCI.
Ethnobotanical study on wild edible plants traditionally used by Messiwa people, Morocco
Authors: Ghanimi Ridwane , Ouhammou Ahmed , Ahouach Abdellah , Cherkaoui Mohamed 
Published: March 2022

AbstractBackgroundThe traditional knowledge on wild edible plants has been shown in many studies a worrying decline throughout the last few decades. Therefore, the first aim of this study was to document the population knowledge on wild edible plants among the Messiwa people. The second objective was to assess the traditional knowledge of our informants according to their socio-economic status.MethodsThe survey was conducted among 149 informants through a semi-structured questionnaire. The relative importance of the plants was obtained by calculating the relative frequency of citation (RFC) for each species. To compare means, we used Student'sttest for two-group comparisons and Snedecor'sF-test for multi-group comparisons. The multi-range Duncan test was used for multiple mean comparisons. The correspondence factor analysis (CFA) was also used.ResultsA set of 64 species belonging to 56 genera from 34 families has been collected and identified. The species used for nutritional and medicinal purposes represent 56%, while 44% were used exclusively as nutritional plants. The most used parts are, respectively, the aerial parts (58%), the fruits (17%), the underground parts (13%), the seeds (8%), and finally the flowers (5%). On the other hand, the higher level of knowledge on wild edible plants was found among women, the elderly, illiterate, married people, and those engaged in agricultural occupations.ConclusionThis work could be a basis to be reproduced on other regions in Morocco and to be widened through pharmacological and nutritional studies in order to promote and valorize these wild edible plants.

Published: March 2022

Abstract
Background
Folk plant nomenclature is a part of knowledge of indigenous people often used to distinguish plant species. This study aimed to document the folk botanical nomenclature of the Yi people in Xiaoliangshan, Yunnan Province, which has not been systematically investigated to date. The results of this study will assist in conserving biodiversity and the language of the Yi people and will promote the transmission of ethnobotanical knowledge.

Methods
An ethnobotanical survey of plants used by the Yi people in Xiaoliangshan, Yunnan Province, was conducted from September 2019 to August 2021. Semi-structured interviews and key informant interviews were conducted to collect and document ethnobotanical information, which was then used to analyse the folk botanical nomenclature of the Yi people. In addition, the folk names of plants used by the Xiaoliangshan Yi community were compared with those of the Yi people living in the Daliangshan, where the environment is considerably different.

Results
In this study, 266 informants were interviewed, and the names of 228 indigenous plants were extracted from 3088 use reports. The nomenclature used by the local Yi people is based on plant characteristics, plant habitat, plant use, and the local culture. By comparing the folk plant names of the Yi people in Xiaoliangshan with those of the Yi people in Daliangshan, we found that the plant names of the two places have some similarities and also with their own unique characters. The important folk plant names of the Yi people in Xiaoliangshan usually have a monosyllable non-binomial structure or have

"Image missing"

and "divine attributes" in their names.

Conclusions
The Yi people in Xiaoliangshan have a rich and diverse knowledge of plant naming determined by cultural, and environmental factors. The botanical nomenclature of the Yi people has distinct rules and characteristics, and the plant naming directly includes important plants that they believe to be used and protected, which is of great significance to the protection of biodiversity.
Predicting yellow rust in wheat breeding trials by proximal phenotyping and machine learning
Authors: Koc Alexander , Odilbekov Firuz , Alamrani Marwan , Henriksson Tina , Chawade Aakash 
Published: March 2022

Abstract
Background
High-throughput plant phenotyping (HTPP) methods have the potential to speed up the crop breeding process through the development of cost-effective, rapid and scalable phenotyping methods amenable to automation. Crop disease resistance breeding stands to benefit from successful implementation of HTPP methods, as bypassing the bottleneck posed by traditional visual phenotyping of disease, enables the screening of larger and more diverse populations for novel sources of resistance. The aim of this study was to use HTPP data obtained through proximal phenotyping to predict yellow rust scores in a large winter wheat field trial.

Results
The results show that 40–42 spectral vegetation indices (SVIs) derived from spectroradiometer data are sufficient to predict yellow rust scores using Random Forest (RF) modelling. The SVIs were selected through RF-based recursive feature elimination (RFE), and the predicted scores in the resulting models had a prediction accuracy of rs = 0.50–0.61 when measuring the correlation between predicted and observed scores. Some of the most important spectral features for prediction were the Plant Senescence Reflectance Index (PSRI), Photochemical Reflectance Index (PRI), Red-Green Pigment Index (RGI), and Greenness Index (GI).

Conclusions
The proposed HTPP method of combining SVI data from spectral sensors in RF models, has the potential to be deployed in wheat breeding trials to score yellow rust.

AbstractBackgroundPostoperative acute kidney injury (AKI) in acute DeBakey type I aortic dissection (ADIAD) is common but has unclear pathogeneses and limited treatments. Receptor-interacting protein kinase 3 (RIP3), a mediator of necroptosis, is associated with human sepsis-induced and posttraumatic AKI, but its role in human postoperative AKI in ADIAD remains unclear. We assumed that RIP3 levels is associated with postoperative AKI in ADIAD.MethodsPlasma samples and the clinical data of continuous patients with ADIAD were collected prospectively. The patients were divided into three groups according to AKI stage postoperatively. The plasma RIP3 levels were compared among the groups, and the relationship between RIP3 and serum creatinine (sCr), inflammatory cytokines as well as clinical results were analyzed.ResultsEighty patients were enrolled. The postoperative and elevated RIP3 levels among the three groups were significantly different (P < 0.0001), both with a positive trend across the AKI stage (Pfor trend < 0.001), and they were also independent risk factors for postoperative AKI in ADIAD (OR = 1.018 and 1.026,P < 0.05). The postoperative RIP3 levels were positively correlated with the aortic crossclamp time (R = 0.253,P < 0.05); the peak values of sCr, procalcitonin, interleukin-6 and lactate postoperatively; the mechanical ventilation time; and the ICU stay time (R = 0.66, 0.369, 0.409, 0.397, 0.474 and 0.435, respectively; allP < 0.001). Plasma RIP3 level and sCr were comparable in diagnosing postoperative AKI in ADIAD (P = 0.898), and higher postoperative RIP3 level was associated with lower survival rate.ConclusionThe plasma RIP3 levels are associated with postoperative AKI, inflammatory response and clinical outcomes in ADIAD.
