Measurement of coherent vibrational dynamics with X-ray Transient Absorption Spectroscopy simultaneously at the Carbon K- and Chlorine L2,3- edges.

X-ray Transient Absorption Spectroscopy (XTAS) is a powerful probe for ultrafast molecular dynamics. The evolution of XTAS signal is controlled by the shapes of potential energy surfaces of the associated core-excited states, which are difficult to directly measure. Here, we study the vibrational dynamics of Raman activated CCl4 with XTAS targeting the C 1s and Cl 2p electrons. The totally symmetric stretching mode leads to concerted elongation or contraction in bond lengths, which in turn induce an experimentally measurable red or blue shift in the X-ray absorption energies associated with inner-shell electron excitations to the valence antibonding levels. The ratios between slopes of different core-excited potential energy surfaces (CEPESs) thereby extracted agree very well with Restricted Open-Shell Kohn-Sham calculations. The other, asymmetric, modes do not measurably contribute to the XTAS signal. The results highlight the ability of XTAS to reveal coherent nuclear dynamics involving  < 0.01 Å atomic displacements and also provide direct measurement of forces on CEPESs.

Impact of COVID-19 on continuing professional development: Perspectives of audiologists.

BACKGROUND:  The coronavirus disease 2019 (COVID-19) pandemic triggered unprecedented disruptions to continuing professional development (CPD) activities, which are essential for healthcare professionals (HCPs) to stay abreast on best practices, current knowledge and emerging technologies, ultimately enhancing patient care. Audiologists encountered multiple challenges during the pandemic, necessitating adaptations and innovations in their CPD practices. While literature was published during the pandemic on shifting education systems to online platforms, little is known about its impact on the CPD of young audiologists working in the private sector. METHODS:  A descriptive, qualitative research design was adopted to collect rich data from 11 audiologists using online semi-structured interviews which were thematically analysed using Braun and Clark's steps. RESULTS:  COVID-19 brought about both positive adaptations and negative disruptions to the CPD activities of young audiologists. Eight major themes were identified in this study. These include (1) the adoption of online learning, (2) improved flexibility, (3) cost-effectiveness, (4) diverse learning opportunities, (5) keeping current, (6) isolation and networking, (7) limited interactivity and (8) uncertain quality assurance. CONCLUSION:  The COVID-19 pandemic had a considerable influence on the CPD activities of young audiologists in the private sector. While presenting significant challenges, including disruptions to traditional learning modalities, the pandemic also catalysed innovation and adaptation within the profession.Contribution: This study highlights the resilience exhibited by young audiologists towards their CPD and also provides actionable insights for informing professional development initiatives, tailored to the evolving needs of audiologists in the post-COVID-19 era.

Doctors' understanding of their learning and learning needs in Kwazulu-Natal district hospitals.

BACKGROUND:  Medicine is a self-regulating profession. Doctors must learn how to self-regulate to keep up-to-date with evolving health care needs. This is challenging for those working at District Hospitals (DHs) in rural settings, where limited resources and understaffing may compound a poor approach and understanding of how to become a self-directed learner. AIM:  To explore perspectives of doctors working in rural DHs, regarding their understanding of learning and learning needs. SETTING:  This study was conducted in Bethesda and Mseleni DHs, in rural KwaZulu-Natal. METHODS:  This was a qualitative study. Data was collected through 16 semi-structured interviews and non-participatory observations. RESULTS:  Four major themes emerged: "Why I learn," "What I need to learn," "How I learn," and our learning environment." This paper focussed on the first three themes. Doctors' learning is influenced by various factors, including their engagement with clinical practice, personal motivation, and their learning process. Deliberate practice and engagement in reflective practice as key principles for workplace learning became evident. CONCLUSION:  In rural DHs, doctors need to take a proactive self-regulated approach to their learning due to difficulties they encounter. They must build competence, autonomy, a sense of connection in their learning process, thus recognizing the need for continuous learning, motivating themselves, and understanding where they lack knowledge, all essential for achieving success.Contribution: This article contributes towards strengthening medical education in African rural context, by empowering medical educators and facility managers to meet the learning needs of doctors, thus contributing to the provision of quality health care.

Medical student learning on a distributed training platform in rural district hospitals.

BACKGROUND:  Decentralising medical school training enhances curriculum relevance, exposing students to generalist patient care in diverse contexts. AIM:  The aim of the study was to understand the student experiences of learning during their 7-week Family Medicine rural rotation. SETTING:  Final year medical students who had completed their Family Medicine rotation in November 2022. METHODS:  A qualitative study involving 24 final year students (four semi- structured interviews and four focus group discussions [4 x 5 students]). All interviews were recorded, transcribed verbatim and analysed thematically. RESULTS:  Analysis revealed positive learning experiences and identified the following themes: taking responsibility for learning, the generalist context, teaching and learning in context and managing the learning environment. CONCLUSION:  Active participation in hospital activities, exposure to disorientating dilemmas that challenged assumptions and reflection on these experiences led to transformative learning and knowledge co-construction.Contribution: The study contributes to the discussion and reinforces the advantages of distributed, experiential training, highlighting the positive impact of meaningful participation and transformative learning opportunities.

Continuing professional development barriers and recommendations: Perspectives of audiologists.

BACKGROUND:  Continuing professional development (CPD), a compulsory requirement of the Health Professions Council of South Africa (HPCSA), is undertaken by healthcare professionals (HCPs), including audiologists, to remain up-to-date with the latest developments, technology and best practices within their discipline. However, the low compliance rates of audiologists engaging in CPD need to be investigated to establish the barriers that audiologists encounter as well as possible interventions to improve their participation. OBJECTIVES:  This study aimed to explore the barriers that audiologists encounter when participating in CPD activities and to highlight their suggestions for improving its uptake. METHOD:  The descriptive qualitative research design entailed the use of semi-structured online interviews with 11 audiologists practising within the private sector in the province of KwaZulu-Natal, South Africa, their responses being thematically analysed. RESULTS:  Three barriers were identified, namely: (1) personal, (2) financial and (3) structural barriers, with eight subthemes and nine recommendations provided by participants. CONCLUSION:  It is anticipated that implementing the proposed strategies will address the barriers and allow active engagement of audiologists in their continued education.Contribution: Limited literature has been documented on the barriers that young, private sector audiologists encounter within the South African context while also providing suggestions to address these barriers.

Dataset: a social accounting matrix for Germany.

OBJECTIVES: The Social Accounting Matrix (SAM) is an extension of Input-Output tables that records macro and meso-economic accounts of a socio-economic system. Its main objective is to provide a comprehensive understanding of the interrelationships among different economic sectors and agents. The SAM can be used for various purposes, including economic analysis, policy evaluation, and economic modelling. It allows policymakers to make more informed decisions, understand potential consequences of different policy options and serve as the foundation for constructing Computable General Equilibrium (CGE) models. DATA DESCRIPTION: The SAM for Germany is a comprehensive source of data that reveals the incomes and expenditures of 163 different production sectors, along with data on factors of production, households, corporations, government, and external accounts with the rest of the world. Additionally, it provides information on gross fixed capital formation, changes in inventories, and natural capital accounts. This SAM was compiled by extending the EXIOBASE Input-Output (IO) accounts with data from the Federal Statistical Office of Germany. Balancing items were also used to ensure that the Total Income and Total Expenditure of the main transactors are in balance.

Patterns of childhood maltreatment and maternal substance use disorder on the development of emerging adult offspring substance use.

Exposure to child maltreatment and maternal substance use disorder represent two highly consequential and co-occurring experiences of family-level adversity for the development of concerning substance use behaviors among offspring. The present study uses latent class analysis to identify how characteristics of childhood maltreatment and maternal substance use disorder naturally cluster. Further, this study investigates how distinct patterns of maltreatment and maternal substance use differentially predict emerging adult substance use in offspring. Participants (N = 405) were drawn from a longitudinal follow-up study of emerging adults who participated in a research summer camp program as children. Wave 1 of the study included 674 school-aged children with and without maltreatment histories, all of whom experienced low socioeconomic status. Patterns of child maltreatment experiences, based on coded Child Protective Services record data, and maternal substance use behaviors, per a diagnostic interview, were used to predict Wave 2 (emerging adulthood) substance use. Results indicated that children who were exposed to a pattern of multitype maltreatment and multitype maternal substance dependence, relative to those exposed to multitype maltreatment alone, reported greater alcohol dependence symptoms during emerging adulthood. Additionally, these same individuals reported greater past-year hard liquor consumption relative to those who experienced chronic, multitype maltreatment and maternal alcohol dependence. These findings highlight how a pattern of maternal polysubstance use and multitype maltreatment is particularly consequential for the intergenerational transmission of substance use behaviors.

Conceptualising the experiences of continuing professional development of young private sector audiologists as an attribute of andragogy.

Background: Continuing professional development (CPD) is an ongoing learning process that builds on initial training and education to improve competency. Low compliance rates of audiologists adhering to CPD have been reported by the Health Professions Council of South Africa. However, there is an absence of research on the uptake of CPD from the perspective of young audiologists working in the private sector. Aim: This study aimed to explore the experiences and views of young audiologists working in the private sector on continuing professional development. Setting: The study was conducted in KwaZulu-Natal province, South Africa. Methods: The descriptive, qualitative approach entailed conducting 11 online, semi-structured interviews with audiologists working in the private sector. Semi-structured interviews consisted of open-ended questions, and the qualitative data were thematically analysed. The adult learning theory, andragogy, was used as both the conceptual and analytical framework. Results: Five andragogy concepts were used to analyse the data, with eight sub-themes emerging related to: self-concept, adult learning experiences, readiness to learn, orientation to learning and internal motivation. Conclusion: The experiences of audiologists in the private sector on CPD aligned with the concepts of andragogy. Audiologists' experiences need to be taken into consideration during the planning and implementation of CPD for it to be relevant, effective and purposeful. Contribution: This study highlighted the experiences of audiologists on CPD working in the private sector with continuing professional development.

Utilization of Hip or Knee MRI in Patients 50 Years and Older With Atraumatic Pain: An Analysis of the National Ambulatory Medical Care Survey.

PURPOSE: The aim of this study was to use the National Ambulatory Medical Care Survey database to assess MRI utilization in patients 50 years and older with atraumatic hip or knee pain. METHODS: National Ambulatory Medical Care Survey weighted survey data (2007-2019) were obtained for ambulatory visits in patients 50 years and older with atraumatic hip or knee pain. The outcome variable was MRI ordering status, and analyzed characteristics included patient age, race/ethnicity, payer, physician specialty, metropolitan statistical area, and a coexistent radiography order. Multivariable logistic regressions were conducted to assess the association between MRI ordering status and the analyzed patient characteristics. All tests were two sided, and P values ≤.05 were considered to indicate statistical significance. RESULTS: In total, 88,978,804 knee pain and 28,675,725 hip pain patient visits (survey weighted) were analyzed, with 4,690,943 (5.3%) and 2,023,226 (7.1%) having knee or hip MRI orders, respectively. Overall, 2,454,433 knee pain visits (2.8%) and 575,155 hip pain visits (2.0%) had orders for both MRI and radiographs. Black patients (P = .03) and patients 80 years and older (P = .04) were less likely to have knee MRI ordered, whereas uninsured patients were less likely to have hip MRI ordered (P = .01). Patients with hip pain were more likely to have hip MRI ordered if seen by a surgical subspecialist (P = .01). CONCLUSIONS: A low proportion of MRI examinations were ordered for visits in patients 50 years and older with atraumatic hip or knee pain. Groups with lower health care access were less likely to have an MRI order, highlighting known disparities in health care equity.

Technical factors associated with the benefit of prophylactic pancreatic stent placement during high-risk ERCP: a secondary analysis of the SVI trial dataset.

BACKGROUND: Prophylactic pancreatic stent placement (PSP) is effective for preventing pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP) in high-risk cases, but the optimal technical approach to this intervention remains uncertain. METHODS: In this secondary analysis of 787 clinical trial participants who underwent successful stent placement, we studied the impact of: 1) whether pancreatic wire access was achieved for the sole purpose of PSP or naturally during the conduct of the case; 2) the amount of effort expended on PSP; 3) stent length; 4) stent diameter; and 5) guidewire caliber. We used logistic regression models to examine the adjusted association between each technical factor and post-ERCP pancreatitis (PEP). RESULTS: Ninety-one of the 787 patients experienced PEP. There was no clear association between PEP and whether pancreatic wire access was achieved for the sole purpose of PSP (vs. occurring naturally; OR 0.82, 95%CI 0.37-1.84), whether substantial effort expended on stent placement (vs. non-substantial effort; OR 1.58, 95%CI 0.73-3.45), stent length (>5 cm vs. ≤5 cm; OR 1.01, 95%CI 0.63-1.61), stent diameter (≥5 Fr vs. <5 Fr; OR 1.13, 95%CI 0.65-1.96), or guidewire caliber (0.035 inch vs. 0.025 inch; 0.83, 95%CI 0.49-1.41). CONCLUSIONS: The 5 modifiable technical factors studied in this secondary analysis of large-scale randomized trial data did not appear to have a strong impact on the benefit of prophylactic pancreatic stent placement in preventing PEP after high-risk ERCP. Within the limitations of post hoc subgroup analysis, these findings may have important implications in procedural decision-making and suggest that the benefit of PSP is robust to variations in technical approach.

Protocol for a systematic review with prospective individual patient data meta-analysis in EGFR-mutant NSCLC with brain metastases to assess the effect of SRS+osimertinib compared to osimertinib alone: the STARLET Collaboration.

BACKGROUND: Patients with advanced non-small-cell lung cancer (NSCLC) with activating mutations in the epidermal growth factor receptor (EGFR) gene are a heterogeneous population who often develop brain metastases (BM). The optimal management of patients with asymptomatic brain metastases is unclear given the activity of newer-generation targeted therapies in the central nervous system. We present a protocol for an individual patient data (IPD) prospective meta-analysis to evaluate whether the addition of stereotactic radiosurgery (SRS) before osimertinib treatment will lead to better control of intracranial metastatic disease. This is a clinically relevant question that will inform practice. METHODS: Randomised controlled trials will be eligible if they include participants with BM arising from EGFR-mutant NSCLC and suitable to receive osimertinib both in the first-line and second-line settings (P); comparisons of SRS followed by osimertinib versus osimertinib alone (I, C) and intracranial disease control included as an endpoint (O). Systematic searches of Medline (Ovid), Embase (Ovid), Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL (EBSCO), PsychInfo, ClinicalTrials.gov and the WHO's International Clinical Trials Registry Platform's Search Portal will be undertaken. An IPD meta-analysis will be performed using methodologies recommended by the Cochrane Collaboration. The primary outcome is intracranial progression-free survival, as determined by response assessment in neuro-oncology-BM criteria. Secondary outcomes include overall survival, time to whole brain radiotherapy, quality of life, and adverse events of special interest. Effect differences will be explored among prespecified subgroups. ETHICS AND DISSEMINATION: Approved by each trial's ethics committee. Results will be relevant to clinicians, researchers, policymakers and patients, and will be disseminated via publications, presentations and media releases. PROSPERO REGISTRATION: CRD42022330532.

Supercritical Water Liquefaction of Mixed Waste Polystyrene, Polypropylene, and Polyethylene for Production of High Yield Oils.

Supercritical water liquefaction of different plastic wastes has been investigated under high-temperature and high-pressure conditions. The supercritical water liquefaction of commonly used plastic types, comprising polystyrene (PS), polypropylene (PP), and low-density polyethylene (LDPE) as well as their mixtures, is reported. The experiments were carried out at varying feedstock-to-water ratios with a residence time of 60 min under supercritical water reaction conditions. The process produced high oil yields of over 97 wt %, with the highest yields obtained at a plastic:water ratio of 1:3; at higher levels of input water, the yield of oil decreased slightly. The gas phase mainly consisted of light hydrocarbons such as methane, ethane, propane, and butane, with propane found to be the most abundant gas component. Aromatic hydrocarbons and alicyclic hydrocarbons were the major products in the product oil from the supercritical water liquefaction of polystyrene and polypropylene, whereas alkanes were predominant in the oil obtained from LDPE. Analysis of the oil obtained from binary (1:1) and ternary (1:1:1) plastic mixtures showed it exhibited aromatic hydrocarbons as the major constituent, indicating synergistic interaction. It was found that the incorporation of PP in the mixture facilitated the production of cyclic compounds and suppressed the production of alkanes. Supercritical water liquefaction offers an effective solution to plastic pollution, producing valuable products without the need for catalysts.

Managing giant omphalocele: A systematic review of surgical techniques and outcomes.

AIM: We analysed closure techniques in the treatment of giant omphalocele. A challenging pathology where there lacks consensus. METHODS: Cochrane, MEDLINE and EMBASE were searched between 1 January 1992 and 31 December 2022 using terms and variations: omphalocele, exomphalos, giant, closure and outcome. Papers were selected using Preferred Reporting Items for Systematic review and Meta-Analyses 2020 criteria. Data collected included demographics, timing and technique of surgical repair, morbidity and mortality. RESULTS: We identified 342 papers; 34 met inclusion criteria with a total 356 neonates. Initial non-operative management was described in 26 papers (14 dressings, eight silo, four serial sac-ligation). Operative techniques by paper were as follows: Early closure: nine primary suture closure without patch, two primary closure with patch and four mixed methods. Delayed closure: five simple, four-component separation technique, four tissue expanders, one Botox/pneumoperitoneum and two with patch. Median number of procedures was two (1-6) in the early group versus three (1-4) in the delayed. The most favourable was early primary closure with biological patch. The most unfavourable was delayed closure with patch. Cumulative reported mortality remained high, mostly due to non-surgical causes. CONCLUSION: Definitions of giant omphalocele in the literature were heterogeneous with a variety of management approaches described.

Protocol for a feasibility registry-based randomised controlled trial investigating a tailored follow-up service for stroke (A-LISTS).

BACKGROUND: Stroke affects long-term physical and cognitive function; many survivors report unmet health needs, such as pain or depression. A hospital-led follow-up service designed to address ongoing health problems may avoid unplanned readmissions and improve quality of life. METHODS: This paper outlines the protocol for a registry-based, randomised controlled trial with allocation concealment of participants and outcome assessors. Based on an intention-to-treat analysis, we will evaluate the feasibility, acceptability, potential effectiveness and cost implications of a new tailored, codesigned, hospital-led follow-up service for people within 6-12 months of stroke. Participants (n = 100) from the Australian Stroke Clinical Registry who report extreme health problems on the EuroQol EQ-5D-3L survey between 90 and 180 days after stroke will be randomly assigned (1:1) to intervention (follow-up service) or control (usual care) groups. All participants will be independently assessed at baseline and 12-14-week post-randomisation. Primary outcomes for feasibility are the proportion of participants completing the trial and for intervention participants the proportion that received follow-up services. Acceptability is satisfaction of clinicians and participants involved in the intervention. Secondary outcomes include effectiveness: change in extreme health problems (EQ-5D-3L), unmet needs (Longer-term Unmet Needs questionnaire), unplanned presentations and hospital readmission, functional independence (modified Rankin Scale) and cost implications estimated from self-reported health service utilisation and productivity (e.g. workforce participation). To inform future research or implementation, the design contains a process evaluation including clinical protocol fidelity and an economic evaluation. DISCUSSION: The results of this study will provide improved knowledge of service design and implementation barriers and facilitators and associated costs and resource implications to inform a future fully powered effectiveness trial of the intervention.

The economics of a national anterior cruciate ligament injury prevention program for amateur football players: a Markov model analysis.

OBJECTIVES: To estimate the long term cost savings, return on investment, and gain in quality-adjusted life years (QALYs) that could be achieved by a national anterior cruciate ligament (ACL) injury prevention program for amateur football (soccer) players in Australia. STUDY DESIGN: Markov model decision analysis. SETTING, PARTICIPANTS: Two hypothetical scenarios including all amateur football players in Australia (340 253 players): no intervention, and a national ACL injury prevention program. Transitions between health states, including ACL rupture, meniscal injury, knee osteoarthritis, and total knee replacement were made in one-year cycles over 35 years from a societal perspective. MAIN OUTCOME MEASURES: Cost savings, return on investment, and QALY gain achieved in the prevention program scenario relative to control scenario, by age group (10-17, 18-34, 35 years or older) and gender. SECONDARY OUTCOMES: incidence of ACL rupture, knee osteoarthritis, total knee replacement, and total knee replacement revision. RESULTS: The total mean cost of an ACL injury was estimated to be $30 665. The national injury prevention program was projected to save $52 539 751 in medical and societal costs caused by ACL ruptures in amateur footballers over 35 years; the estimated return on each dollar invested in the program was $3.51. Over this period, the number of players with ruptured ACLs could be reduced by 4385 (9%), the number of knee osteoarthritis cases by 780 (8.1%), and the number of total knee replacements by 121 (8.1%); 445 QALYs were gained. CONCLUSION: Our findings support investing in a national, evidence-based program for the primary prevention of ACL injuries in amateur football players.

Community service rehabilitation therapists' understanding of social accountability.

BACKGROUND:  Social accountability is the obligation of health care providers to address the priority health concerns of the community they serve and of universities to ensure that graduates understand these social responsibilities. Although social accountability can combat systemic health inefficiencies, it is not well-understood or practised. AIM:  The study aimed to explore community service rehabilitation therapists' understanding of social accountability. SETTING:  The study was conducted in KwaZulu-Natal, South Africa. METHODS:  This study used an interpretive exploratory design and purposively recruited 27 community service rehabilitation therapists namely, audiologists, speech-language therapists, occupational therapists, and physiotherapists working in public sector health facilities in rural and peri-urban areas. Four focus group discussions and four free attitude interviews were conducted, the results being thematically analysed. RESULTS:  Despite most of the participants not being instructed in social accountability as part of their formal training or institutional induction, three themes emerged based on their experiences. These themes include describing social accountability, values of social accountability, and values of community-based rehabilitation applicable to social accountability. CONCLUSION:  Inclusion of instruction on social accountability as part of their formal training and health facility induction would contribute to rehabilitation therapists' understanding of social accountability.Contribution: The study contributes to data on rehabilitation education and community service training regarding social accountability within a South African context and has captured how experiences gained during community service contribute to the rehabilitation therapists' understanding of social accountability.

Social accountability challenges and recommendations by community service rehabilitation therapists.

BACKGROUND:  Social accountability entails providing equitable and accessible services that are tailor-made for the community's healthcare needs and enable rehabilitation therapists to improve the efficiency and efficacy of healthcare delivery and their response. Enabling them to provide optimal care during their community service year requires understanding the gaps in their knowledge, experience and the support they provide to the communities they service. METHODS:  Four in-depth individual interviews and four focus group discussions were conducted via Zoom. The qualitative responses to the questions related to the challenges and recommendations associated with social accountability in clinical settings were analysed using an inductive thematic approach via NVIVO. RESULTS:  Four sub-themes emerged for each of the two areas of interest: the challenges relating to (1) budget and equipment constraints, (2) staff shortages, (3) cultural and language barriers and (4) scope of practice limitations. The recommendations related to (5) collaboration with community caregivers, (6) service inclusion in primary health care clinics, (7) improved executive management support and (8) continuing professional development. CONCLUSION:  Equipping graduates with the knowledge, skills and support needed to work in an under-resourced setting is essential for community service rehabilitation therapists to ensure social accountability, given that they often work alone, specifically in rural settings.Contribution: Being aware of the challenges that face community service rehabilitation therapists, having the necessary tools and health facility management support will enable ongoing improvements in their ability to provide socially accountable services.

Heading in football: a systematic review of descriptors, definitions, and reporting methods used in heading incidence studies.

The primary objective of this systematic review was to describe the number and type of heading descriptors used in all published studies which report on heading incidence in football. The secondary objective was to detail the data collection and reporting methods used in the included studies to present heading incidence data. Eligible studies were identified through searches of five electronic databases: Ovid MEDLINE, CINAHL, EMBASE, SPORTDiscus, and Web of Science, using a combination of free-text keywords (inception to 12th September 2023). Manual searching of reference lists and retrieved systematic reviews was also performed. A descriptive overview and synthesis of the results is presented. From 1620 potentially eligible studies, 71 studies were included, with the following key findings: 1) only 61% of studies defined a header with even fewer (23%) providing an operational definition of a header within the methods; 2) important study and player demographic data including year and country were often not reported; 3) reported heading descriptors and their coding options varied greatly; 4) visual identification of headers was essential when inertial measurement units were used to collect heading incidence data; and 5) there was a lack of standardisation in the reporting methods used in heading incidence studies making comparison between studies challenging. To address these findings, the development of a standardised, internationally supported, operational definition of a header and related heading descriptors should be prioritised. Further recommendations include the development of minimum reporting criteria for heading incidence research.

Draft genome sequence data on Bacillus safensis U41 isolated from soils of Santiniketan, India.

The draft genome sequence of an isolate of Bacillus safensis U41 from the soils of Santiniketan (23040'12″ N and 87039'52″ E) is reported here. Bacillus safensis is a bacterium that produces cellulases, which is essential for the breakdown of plant biomass. As such, it is a valuable source of digestive enzymes from plant biomass, especially cellulases. The genomic DNA was extracted from a single colony using a QIAgen Blood and Tissue kit (QIAgen Inc., Canada). Sequencing was performed via Illumina HiSeq X using 2 × 150 paired-end chemistry, generating 7,352,576 reads with sequence coverage of 509x. The assembly produced 20 contigs over 200 base pairs (bp) in length, with an N50 value of 901304 and an L50 of 2. The genome size was 3,732,407 bp, and the average GC content was 41.43 %. Genome annotation and gene predictions were performed using Prokka v.1.14.6, which identified 3783 coding sequences, 64 tRNA genes, and 3 rRNA genes.
