"Out of the frying pan and into the fire" - the UKFPO's recent changes are a short-sighted response to a complicated problem.

In June 2023, the UK Foundation Programme Office announced that the previous method of ranking students based on their educational performance measure and situational judgement test performance would be superseded by a preferencing algorithm that disregards academic merit. We outline our strong objections to this policy.

Artificial Intelligence-Driven Morphology-Based Enrichment of Malignant Cells from Body Fluid.

Cell morphology is a fundamental feature used to evaluate patient specimens in pathologic analysis. However, traditional cytopathology analysis of patient effusion samples is limited by low tumor cell abundance coupled with the high background of nonmalignant cells, restricting the ability of downstream molecular and functional analyses to identify actionable therapeutic targets. We applied the Deepcell platform that combines microfluidic sorting, brightfield imaging, and real-time deep learning interpretations based on multidimensional morphology to enrich carcinoma cells from malignant effusions without cell staining or labels. Carcinoma cell enrichment was validated with whole genome sequencing and targeted mutation analysis, which showed a higher sensitivity for detection of tumor fractions and critical somatic variant mutations that were initially at low levels or undetectable in presort patient samples. Our study demonstrates the feasibility and added value of supplementing traditional morphology-based cytology with deep learning, multidimensional morphology analysis, and microfluidic sorting.

Healthcare workers preparedness for COVID-19 pandemic in the occupied Palestinian territory: a cross-sectional survey.

BACKGROUND: The COVID-19 pandemic threatens to overwhelm the capacity of a vulnerable healthcare system in the occupied Palestinian territory (oPt). We aimed to evaluate the availability of personal protective equipment (PPE) and the level of preparedness among HCWs in the oPt. METHODS: A cross-sectional study was conducted using a validated online questionnaire distributed through convenient sampling between March 30, 2020 and April 12, 2020. Outcomes were availability of PPE, healthcare workers (HCWs) preparedness in oPt for COVID-19 pandemic, and regional and hospital differences in oPt in terms of availability of PPE and HCWs preparedness. Descriptive statistics and univariate analysis were used in this study. RESULTS: Of 138 respondents, only 38 HCWs (27.5%) always had access to facemasks and 15 (10.9%) always had access to isolation gowns. Most HCWs did not find eye protection (n = 128, 92.8%), N95 respirators (n = 132, 95.7%), and face shields (n = 127, 92%) always available. Compared to HCWs in West Bank, those in the Gaza Strip were significantly less likely to have access to alcohol sanitizers (p = 0.03) and gloves (p < 0.001). On average, governmental hospitals were significantly less likely to have all appropriate PPE than non-governmental institutions (p = 0.001). Only 16 (11.6%) surveyed felt confident in dealing with a potential COVID-19 case, 57 (41.3%) having received any COVID-19-related training, and 57 (41.3%) not having a local hospital protocol. CONCLUSION: HCWs in oPt appear to be underprepared and severely lacking adequate PPE provision. The lack of PPE provision will exacerbate spread of COVID-19 and deepen the crisis, whilst putting HCWs at risk.

Distance-learning collaborations for rapid knowledge sharing to the occupied Palestinian territory during the COVID-19 response: experience from the OxPal partnership.

Distance-learning increasingly forms part of many academic and professional courses. OxPal, a collaboration between University of Oxford medical students and doctors and their counterparts in the occupied Palestinian territory (oPt), sought to evaluate the feasibility and efficacy of interactive online distance-learning through a pre-established international partnership as a method for rapid knowledge sharing during the novel coronavirus disease 2019 (COVID-19) response. Two interactive online lectures for medical students and clinicians in the oPt on the COVID-19 pandemic were conducted. The first lecture was an 'Introduction to COVID-19' and the second focused on 'Data-sharing during the pandemic'. 212 and 174 attended each lecture, respectively. Feedback was via an online questionnaire. >95% of respondents indicated the lectures covered a gap in their medical education. 87% and 77% of respondents rated lecture quality 'Good' or 'Excellent' for the two lectures respectively. Qualitative feedback elicited requests for more clinically focused lectures, which have since been provided. Online lectures are feasible and effective for rapid education of medical students and clinicians in the oPt in a public health emergency. We hope this encourages other institutions to provide similar support in the oPt and other 'tutor-deplete' regions facing specific geopolitical challenges to local medical education.

A rationale for universal tranexamic acid in major joint arthroplasty: overall efficacy and impact of risk factors for transfusion.

BACKGROUND: Tranexamic acid (TXA) therapy is effective in reducing postoperative red blood cell (RBC) transfusion in total joint arthroplasty (TJA), yet uncertainty persists regarding comparative efficacy and safety among specific patient subgroups. We assessed the impact of a universal TXA protocol on RBC transfusion, postoperative hemoglobin (Hb), and adverse outcomes to determine whether TXA is safe and effective in TJA, both overall and in clinically relevant subgroups. STUDY DESIGN AND METHODS: A retrospective observational study was performed on patients undergoing TJA at our institution spanning 1 year before and after the implementation of a universal protocol to administer intravenous (IV) TXA. The primary outcome was percentage of patients transfused, and secondary outcomes were perioperative Hb and occurrence of adverse events (death, myocardial infarction, stroke, seizure, pulmonary embolism, deep vein thrombosis, and acute kidney injury ). Outcomes were compared in pre- and post-protocol groups with χ2 analysis. Logistic regression compared risk of transfusion in pre- and post-protocol subgroups of patients with differing risk for transfusion (anemia, body mass index [BMI], and sex). RESULTS: No differences were found in baseline patient characteristics across pre- and post-protocol groups (n = 1084 and 912, respectively). TXA use increased from 32.3% to 92.2% while transfusion rates decreased from 10.3% to 4.8% (p < 0.001). Postoperative Day 3 Hb increased from 95.8 to 101.4 g/L (p < 0.001). Logistic regression demonstrated reduced transfusion in post-protocol subgroups regardless of sex, anemia, or BMI (p < 0.001). No increase in adverse events was observed (p = 0.8451). CONCLUSIONS: Universal TXA was associated with a reduction of RBC transfusion, overall and in clinically relevant subgroups, strengthening the rationale for universal therapy.

Dental trainee motivations for the acquisition and use of postgraduate qualifications in medical education.

Introduction Medical and dental education is increasingly professionalised. The expectation is that educators have appropriate training and qualifications. Entry to dental speciality training is highly competitive and applications are scored using defined criteria, including experience in education.Material and methods We surveyed a group of junior trainees who had enrolled on postgraduate medical education courses to find out more about their motivations and use of their knowledge and qualifications. An online survey tool was used with anonymous participants who had been in junior training jobs in a university dental school, with 117 possible participants.Results In total, 61% of respondents were enrolled in or had completed a postgraduate qualification in medical education, with 85% on a postgraduate certificate programme. Additionally, 77% were in the earliest part of general dental training, and 88% of programmes were distance-learning and cost £2,000 to £4,000. Motivations for enrolling included to 'improve knowledge in medical education' and 'increase my chances of progression through training'.Discussion and conclusions We found the most common intrinsic reason to gain a qualification was to improve knowledge in medical education and the most common extrinsic reason was career progression. Scoring of applications into dental speciality training has changed, with points no longer awarded for completing a postgraduate qualification in medical education.

COSMOS: a platform for real-time morphology-based, label-free cell sorting using deep learning.

Cells are the singular building blocks of life, and a comprehensive understanding of morphology, among other properties, is crucial to the assessment of underlying heterogeneity. We developed Computational Sorting and Mapping of Single Cells (COSMOS), a platform based on Artificial Intelligence (AI) and microfluidics to characterize and sort single cells based on real-time deep learning interpretation of high-resolution brightfield images. Supervised deep learning models were applied to characterize and sort cell lines and dissociated primary tissue based on high-dimensional embedding vectors of morphology without the need for biomarker labels and stains/dyes. We demonstrate COSMOS capabilities with multiple human cell lines and tissue samples. These early results suggest that our neural networks embedding space can capture and recapitulate deep visual characteristics and can be used to efficiently purify unlabeled viable cells with desired morphological traits. Our approach resolves a technical gap in the ability to perform real-time deep learning assessment and sorting of cells based on high-resolution brightfield images.

Effect of under-nutrition on permanent tooth emergence among Rajputs of Himachal Pradesh, India.

BACKGROUND: The sequence and emergence of permanent teeth are considered to be largely under genetic control. However, some environmental factors have also been reported to influence tooth emergence. AIM: To investigate the effect of under-nutrition on the emergence of permanent teeth in a sample of Rajput children from part of Solan District in Himachal Pradesh State of India. SUBJECTS AND METHODS: This study is based on a cross-sectional sample of 509 school-going boys and girls ranging in age from 5-14 years. The emergence of the first 28 teeth was investigated. The nutritional status of each subject was evaluated using stature and weight expressed as SD scores of weight-for-age, stature-for-age and weight-for-stature of the NCHS reference data. RESULTS: Mandibular teeth tended to emerge earlier than the maxillary teeth in both sexes and, except pre-molars, emergence was earlier in girls. Simple correlation between number of emerged teeth and stature (0.871 in girls, 0.855 in boys) and weight (0.814 in girls, 0.791 in boys) was significant (p ≤ 0.05), but on partialling out the effect of age, values of partial correlation were low and not significant. Under-nourished children of both sexes (those with SD scores of - 2 SD or less) had fewer erupted teeth compared to normal children (with SD scores of - 1 SD and over), according to weight-for-age as well as stature-for-age. However, the differences were less marked in older age groups, that is those above 11 years. When the number of emerged teeth was analysed according to weight-for-stature there was no clear difference in the number of emerged teeth between under-nourished (wasted) and normal children. CONCLUSIONS: Past long-term and chronic under-nutrition may result in delayed emergence of permanent teeth, particularly in younger age groups.

Role of multislice computed tomography in evaluation and management of intestinal obstruction.

THE AIMS AND OBJECTIVES OF THIS STUDY WERE: i) to evaluate the efficacy of computed tomography (CT) imaging in diagnosing the presence, level, degree, and cause of intestinal obstruction, and the role of CT in detecting presence of complications; ii) to assess impact of CT in decision making and management (surgical/conservative); iii) to correlate CT findings with intra operative findings whenever possible. A prospective study of 40 patients presented in outpatient/emergency department with features suggestive of intestinal obstruction. Multislice contrast enhanced computed tomography of whole abdomen was done in all patients after preliminary investigations. Whenever indicated, patients were explored. Statistical analysis was performed to determine the efficacy of multidetector computed tomography (MDCT) in diagnosing intestinal obstruction and its complications. Out of 40, 30 patients underwent exploratory laparotomy and it was found that MDCT was 85% sensitive and 70% specific in diagnosing bowel obstruction. Association between MDCT findings suggestive of obstruction and intra-operative findings turn out to be significant (P=0.003). MDCT findings were consistent with intraoperative findings in 22 out of 30 patients (73%). MDCT is sensitive and specific in determining the presence of bowel obstruction and should be recommended for patients with suspected bowel obstruction because it affects outcome in these patients.
