BACKGROUND
There exists consistent empirical evidence in the literature pointing out ample heterogeneity in terms of the clinical evolution of patients with COVID-19. The identification of specific phenotypes underlying in the population might contribute towards a better understanding and characterization of the different courses of the disease. The aim of this study was to identify distinct clinical phenotypes among hospitalized patients with SARS-CoV-2 pneumonia using machine learning clustering, and to study their association with subsequent clinical outcomes as severity and mortality.
METHODS
Multicentric observational, prospective, longitudinal, cohort study conducted in four hospitals in Spain. We included adult patients admitted for in-hospital stay due to SARS-CoV-2 pneumonia. We collected a broad spectrum of variables to describe exhaustively each case: patient demographics, comorbidities, symptoms, physiological status, baseline examinations (blood analytics, arterial gas test), etc. For the development and internal validation of the clustering/phenotype models, the dataset was split into training and test sets (50% each). We proposed a sequence of machine learning stages: feature scaling, missing data imputation, reduction of data dimensionality via Kernel Principal Component Analysis (KPCA), and clustering with the k-means algorithm. The optimal cluster model parameters -including k, the number of phenotypes- were chosen automatically, by maximizing the average Silhouette score across the training set.
RESULTS
We enrolled 1548 patients, each of them characterized by 92 clinical attributes (d=109 features after variable encoding). Our clustering algorithm identified k=3 distinct phenotypes and 18 strongly informative variables: Phenotype A (788 cases [50.9% prevalence] - age 57, Charlson comorbidity 1, pneumonia CURB-65 score 0 to 1, respiratory rate at admission 18 min, FiO 21%, C-reactive protein CRP 49.5 mg/dL [median within cluster]); phenotype B (620 cases [40.0%] - age 75, Charlson 5, CURB-65 1 to 2, respiration 20 min, FiO 21%, CRP 101.5 mg/dL); and phenotype C (140 cases [9.0%] - age 71, Charlson 4, CURB-65 0 to 2, respiration 30 min, FiO 38%, CRP 152.3 mg/dL). Hypothesis testing provided solid statistical evidence supporting an interaction between phenotype and each clinical outcome: severity and mortality. By computing their corresponding odds ratios, a clear trend was found for higher frequencies of unfavourable evolution in phenotype C with respect to B, as well as more unfavourable in phenotype B than in A.
CONCLUSION
A compound unsupervised clustering technique (including a fully-automated optimization of its internal parameters) revealed the existence of three distinct groups of patients - phenotypes. In turn, these showed strong associations with the clinical severity in the progression of pneumonia, and with mortality.

Implementation of an ISO 15189 accredited next generation sequencing service for cell-free total nucleic acid (cfTNA) analysis to facilitate driver mutation reporting in blood: the experience of a clinical diagnostic laboratory.
AIMS
Next generation sequencing (NGS) on tumour tissue is integral to the delivery of personalised medicine and targeted therapy. NGS on liquid biopsy, a much less invasive technology, is an emerging clinical tool that has rapidly expanded clinical utility. Gene mutations in cell-free total nucleic acids (cfTNA) circulating in the blood are representative of whole tumour biology and can reveal different mutations from different tumour sites, thus addressing tumour heterogeneity challenges.
METHODS
The novel Ion Torrent Genexus NGS system with automated sample preparation, onboard library preparation, templating, sequencing, data analysis and Oncomine Reporter software was used. cfTNA extracted from plasma was verified with the targeted pan-cancer (~50 genes) Oncomine Precision Assay (OPA). Assessment criteria included analytical sensitivity, specificity, limits of detection (LOD), accuracy, repeatability, reproducibility and the establishment of performance metrics.
RESULTS
An ISO 15189 accredited, minimally invasive cfTNA NGS diagnostic service has been implemented. High sensitivity (>83%) and specificity between plasma and tissue were observed. A sequencing LOD of 1.2% was achieved when the depth of coverage was >22 000×. A reduction (>68%) in turnaround time (TAT) of liquid biopsy results was achieved: 5 days TAT for in-house analysis from sample receipt to a final report issued to oncologists as compared with >15 days from reference laboratories.
CONCLUSION
Tumour-derived somatic variants can now be reliably assessed from plasma to provide minimally invasive tumour profiling. Successful implementation of this accredited service resulted in:Appropriate molecular profiling of patients where tumour tissue is unavailable or inaccessible.Rapid TAT of plasma NGS results.

Review
In 2021, a 'call to action' was published to highlight the need for professional regulation of clinical exercise physiologists to be established within UK healthcare systems to ensure patient safety and align training and regulation with other health professions. This manuscript provides a progress report on the actions that Clinical Exercise Physiology UK (CEP-UK) has undertaken over the past 4 years, during which time clinical exercise physiologists have implemented regulation and gained formal recognition as healthcare professionals in the UK. An overview of the consultation process involved in creating a regulated health profession, notably the development of policies and procedures for both individual registration and institutional master's degree (MSc) accreditation is outlined. Additionally, the process for developing an industry-recognised scope of practice, a university MSc-level curriculum framework, the Academy for Healthcare Science Practitioner standards of proficiency and Continuing Professional Development opportunities is included. We outline the significant activities and milestones undertaken by CEP-UK and provide insight and clarity for other health professionals to understand the training and registration process for a clinical exercise physiologist in the UK. Finally, we include short, medium and long-term objectives for the future advocacy development of this workforce in the UK.

PURPOSE
Patient safety incidents in the operating room require special attention because they can cause catastrophic and irreversible conditions in patients. Although patient safety incidents have different characteristics, there may be similarities and patterns of risk factors that may be common. Therefore, this study analyzed factors associated with the PSIs by analyzing data from the Korean Patient Safety Reports from 2017 to 2019.
METHODS
The "Patient Safety Incidents Data from 2017 to 2021" systematically collected by the Korea Institute for Healthcare Accreditation, include patient safety incident reports from medical institutions. Data on 1140 patient safety incidents in the operating room were analyzed. They included patients' gender and age, Hospital size, Incident seasons, incident time, Incident reporter, incident type, Medical department, and Incident severity. The Incident severity was analyzed by dividing it into three stages: near miss, adverse event, sentinel event, which are applied by domestic medical institutions.
RESULTS
The highest number of OR patient safety incidents were related to surgery and anesthesia. On analyzing the probability of adverse events based on near misses, the significant variables were patient gender, incident reporter, incident type, and Medical department. Additionally, the factors that were likely to precipitate sentinel events based on near misses were patient gender, incident time, reporter, and incident type.
CONCLUSION
To prevent sentinel events in Patient safety incidents, female and during night shifts are required to pay close attention. Moreover, it is necessary to establish a patient safety reporting system in which not only all medical personnel, but also patients, generally, can actively participate in patient safety activities.

INTRODUCTION
Chronic workplace stress and burnout are impediments to physicians' professional fulfillment, healthcare organizations' efficiency, and patient care quality/safety. General surgery residents are especially at risk due to the complexity of their training. We report the protocol of a metaanalysis of chronic stress and burnout among Accreditation Council for Graduate Medical Education (ACGME)-affiliated general surgery residents in the era after duty-hour reforms, plus downstream effects on their health and clinical performance.
METHODS
The proposed systematic review and metaanalysis (PROSPERO registration CRD42021277626) will synthesize/pool data from studies of chronic stress and burnout among general surgery residents at ACGME-affiliated programs. The timeframe under review is subdivided into three intervals: (a) after the 2003 duty-hour restrictions but before 2011 reforms, (b) after the 2011 reforms but before the coronavirus pandemic, and (c) the first 3 years after the pandemic's outbreak. Only studies reporting outcomes based on validated instruments will be included. Qualitative studies, commentaries/editorials, narrative reviews, and studies not published in English will be excluded. Multivariable analyses will adjust for sample characteristics and the methodological quality of included studies.
CONCLUSIONS
The metaanalysis will yield evidence reflecting experiences of North American-based general surgery residents in the years after ACGME-mandated duty-hour restructuring.

Queensland Trauma Education (QTE): an innovative simulation program that addresses the needs and barriers of interprofessional trauma care education across a complex landscape.
INTRODUCTION
Effective trauma care requires the rapid management of injuries. Rural and remote areas face inequity in trauma care due to time, distance and resource constraints, and experience higher morbidity and mortality rates than urban settings. A training needs analysis (TNA) conducted with stakeholders across Queensland, Australia, revealed a lack of contextual, accessible and interprofessional trauma education for clinicians. The Clinical Skills Development Service and Jamieson Trauma Institute developed the Queensland Trauma Education (QTE) program to address these concerns. QTE comprises a face-to-face training course and open access to online training resources created and reviewed by trauma experts. QTE also supports local training through a statewide simulation network and free access to simulation training equipment. The aim of this article is to review the QTE program and assess the benefits to clinicians in both the delivery of education and the provision of trauma care.
METHODS
To evaluate the QTE program, a desktop review was conducted. This included analyses of website data, course and website content, and facilitator, stakeholder, participant and user feedback. The data were evaluated using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework, and the program's alignment with the original TNA outcomes was assessed.
RESULTS
The results showed that QTE aligns with the identified training needs. Specifically, QTE provides trauma education that is relevant, sustainable, employs best practice, is locally delivered, provides continuous support, is multidisciplinary, multi-platformed, physically accessible and accredited by the Australasian College for Emergency Medicine. The review also highlights how QTE has effectively been reaching its target population, improves knowledge and skills, has become widely adopted, and been implemented and maintained with relative success.
CONCLUSION
The innovative QTE program addresses the previous deficits in trauma education and meets the needs identified in the TNA. The review also reveals further opportunities for continuous improvement and program sustainability.

Randomized Controlled Trial
BACKGROUND
The disability and significant economic costs accredited to Low back pain (LBP) are likely to rise which is an essential problem in low and middle-income countries like Pakistan. The associated factors of LBP are age, sex, and race including physical activity, high spinal load, lifting, bending, and twisting occupations. The literature highlighted there is substantial differences in associated factors of LBP within available studies in developing countries. The objective is to investigate the association of demographic factors and lumbar range of motion with disability in patients with chronic low back.
METHODS
A baseline data analysis was performed as an analytical cross-sectional study among 150 patients with chronic low back in a randomized controlled trial with a duration from March 2020 and January 2021. After recording demographics, Modified-Modified Schober's test was used to measure lumbar flexion and extension and Oswestry disability index for disability. After the descriptive analysis the continuous variables, age and pain were analyzed with Spearman's correlation. Variables that were significant in bivariate analysis were then fitted in a multivariable linear regression. The Kruskal-Wallis test was used to analyze variations of disability in gender, marital status, work status, education level, and duration of pain. The p-value of 0.05 was significant.
RESULTS
The results showed a significant correlation between age and pain in sitting (rh=-0.189, p = 0.021 and rh = 0.788, p < 0.001) with the disability but no significant effects of age and pain in sitting (B=-0.124, p = 0.212 and B = 1.128, p = 0.082) on disability were found. The decrease in lumbar flexion and extension was found to increase disability (B=-6.018 and - 4.032 respectively with p < 0.001). Female gender (x2(1) = 15.477, p = < 0.001) and unmarried marital status (x2(1) = 4.539, p = 0.033) had more disability than male gender and married marital status, respectively. There was a significance between groups of the duration of pain regarding disability (x2 (2) = 70.905, p < 0.001). Age, education level, and work status showed no significance (p > 0.05).
CONCLUSIONS
The female gender and unmarried marital status are associated with functional disability. Decreased lumbar range of motion accompanies more disability, while age, education level, and work status do not effect on disability.

As Designated Institutional Officer (LMB) and Program Director (EM) in a community teaching hospital, we are intimately involved with all aspects of Graduate Medical Education (GME) and find the rewarding part to consist of contributing towards the teaching of our future physicians, as well as the challenges imposed by the continuously evolving training requirements as set forth by the Accreditation Council for Graduate Medical Education (ACGME). While we are very aware of the standard training requisites that are put in place without exception for all accredited GME residency programs, whether they are part of a major (University) or minor (Community) teaching medical center, in this manuscript we are hoping to perhaps initiate a dialogue among clinical educators as to the future of graduate medical training, and how we as a medical community can commit to providing the best education experience for our residents, while preparing them to be the physicians our patients expect and deserve.

Smokeless tobacco (ST) use in South Asia is culturally ingrained and socially accepted. A better understanding of these sociocultural influences could inform behavioural approaches to prevent ST use. We sought to understand how family members influence pregnant women's behaviour, attitudes, and perceptions towards ST use. Moreover, we captured the influence of community health workers in this context. A qualitative study using a framework analysis was conducted in selected Indian populations. Eight in-depth interviews among pregnant and postpartum women were conducted in Gujarati, the local language, investigating ST use during pregnancy and the influence of family and peers. All transcripts were transcribed verbatim and translated into English and analyzed in NVivo. The social norms and expectations around ST during pregnancy appeared to have shifted away from promoting towards discouraging its use in the past few years. Women described how their spouses and other family members encouraged them to stop using ST during pregnancy, with some women must hide their ST use from their family members. They also received advice on the harms of ST use from community health workers (Accredited Social Health Activist-ASHA workers). Influenced by the advice received from such workers, several women tried to reduce their ST use during pregnancy. Our findings suggest that the acceptability of ST use in pregnancy may be in decline among families in India. Hence, efforts to promote ST prevention during pregnancy are likely to be "pushing against an open door". Furthermore, community health workers appeared to play an influential role in supporting women to abstain from ST use during pregnancy.

Detection of high glycated hemoglobin (A1c) is associated with worse postoperative outcomes, including predisposition to develop systemic and local infectious events. Diabetes and infectious Outcomes in Cardiac Surgery (DOCS) study is a retrospective case-control study aimed to assess in DM and non-DM cardiac surgery patients if a new screening and management model, consisting of systematic A1c evaluation followed by a specialized DM consult, could reduce perioperative infections and 30-days mortality. Effective July 2021, all patients admitted to the cardiac surgery of IRCCS ISMETT were tested for A1c. According to the new protocol, glucose values of patients with A1c ≥ 6% or with known diabetes were monitored. The diabetes team was activated to manage therapy daily until discharge or provide indications for the diagnostic-therapeutic process. Propensity score was used to match 573 patients managed according to the new protocol (the Screen+ Group) to 573 patients admitted before July 2021 and subjected to the traditional management (Screen-). Perioperative prevalence of infections from any cause, including surgical wound infections (SWI), was significantly lower in the Screen+ as compared with the Screen- matched patients (66 [11%] vs. 103 [18%] p = 0.003). No significant difference was observed in 30-day mortality. A1c analysis identified undiagnosed DM in 12% of patients without known metabolic conditions. In a population of patients undergoing cardiac surgery, systematic A1c evaluation at admission followed by specialist DM management reduces perioperative infectious complications, including SWI. Furthermore, A1c screening for patients undergoing cardiac surgery unmasks unknown DM and enhances risk stratification.
