Improving weekend handover between junior doctors on medical and surgical wards.

Poor weekend handover has been implicated as one of the causes of observed higher mortality rates at weekends in UK hospitals. In a large teaching hospital we, a group of junior doctors, set about improving the quality and effectiveness of weekend handover. We used the Model for Improvement to implement a weekend handover sticker through an iterative process using multiple Plan/Do/Study/Act (PDSA) cycles. Over the 16 week study period the number of completed weekend tasks increased by 30% and the number of patients with a documented weekend handover increased by nearly 50%. Junior doctors are well positioned to notice the quality and safety shortcomings within hospitals, and by using effective improvement methods they can improve these systems at little or no cost.This article is freely available via Open Access.

Thalamostriatal disconnection underpins long-term seizure freedom in frontal lobe epilepsy surgery

Around 50% of patients undergoing frontal lobe surgery for focal drug-resistant epilepsy become seizure free post-operatively; however, only about 30% of patients remain seizure free in the long-term. Early seizure recurrence is likely to be caused by partial resection of the epileptogenic lesion, whilst delayed seizure recurrence can occur even if the epileptogenic lesion has been completely excised. This suggests a coexistent epileptogenic network facilitating ictogenesis in close or distant dormant epileptic foci. As thalamic and striatal dysregulation can support epileptogenesis and disconnection of cortico-thalamostriatal pathways through hemispherotomy or neuromodulation can improve seizure outcome regardless of focality, we hypothesize that projections from the striatum and the thalamus to the cortex may contribute to this common epileptogenic network. To this end, we retrospectively reviewed a series of 47 consecutive individuals who underwent surgery for drug-resistant frontal lobe epilepsy. We performed voxel-based and tractography disconnectome analyses to investigate shared patterns of disconnection associated with long-term seizure freedom. Seizure freedom after 3 and 5 years was independently associated with disconnection of the anterior thalamic radiation and anterior cortico-striatal projections. This was also confirmed in a subgroup of 29 patients with complete resections, suggesting these pathways may play a critical role in supporting the development of novel epileptic networks. Our study indicates that network dysfunction in frontal lobe epilepsy may extend beyond the resection and putative epileptogenic zone. This may be critical in the pathogenesis of delayed seizure recurrence as thalamic and striatal networks may promote epileptogenesis and disconnection may underpin long-term seizure freedom

PDBe supports diverse research communities in their use of macromolecular structures by enriching the PDB data and by providing advanced tools and services for effective data access, visualization and analysis. This paper details the enrichment of data at PDBe, including mapping of RNA structures to Rfam, and identification of molecules that act as cofactors. PDBe has developed an advanced search facility with ∼100 data categories and sequence searches. New features have been included in the LiteMol viewer at PDBe, with updated visualization of carbohydrates and nucleic acids. Small molecules are now mapped more extensively to external databases and their visual representation has been enhanced. These advances help users to more easily find and interpret macromolecular structure data in order to solve scientific problems.The Protein Data Bank in Europe is supported by European Molecular Biology Laboratory-European Bioinformatics Institute; Wellcome Trust [104948]; Biotechnology and Biological Sciences Research Council [BB/N019172/1, BB/G022577/1, BB/J007471/1, BB/K016970/1, BB/K020013/1, BB/M013146/1, BB/M011674/1, BB/M020347/1, BB/M020428/1, BB/P024351/1]; European Union [284209]; ELIXIR and Open Targets.

Impact of meningococcal ACWY conjugate vaccines on pharyngeal carriage in adolescents: evidence for herd protection from the UK MenACWY programme

Objective: Serogroup W and Y invasive meningococcal disease increased globally from 2000 onwards. Responding to a rapid increase in serogroup W clonal complex 11 (W:cc11) invasive meningococcal disease, the UK replaced an adolescent booster dose of meningococcal C conjugate vaccine with quadrivalent MenACWY conjugate vaccine in 2015. By 2018, the vaccine coverage in the eligible school cohorts aged 14 to 19 years was 84%. We assessed the impact of the MenACWY vaccination programme on meningococcal carriage. Methods: An observational study of culture-defined oropharyngeal meningococcal carriage prevalence before and after the start of the MenACWY vaccination programme in UK school students, aged 15 to 19 years, using two cross-sectional studies: 2014 to 2015 “UKMenCar4” and 2018 “Be on the TEAM” (ISRCTN75858406). Results: A total of 10 625 participants preimplementation and 13 434 postimplementation were included. Carriage of genogroups C, W, and Y (combined) decreased from 2.03 to 0.71% (OR 0.34 [95% CI 0.27–0.44], p < 0.001). Carriage of genogroup B meningococci did not change (1.26% vs 1.23% [95% CI 0.77–1.22], p = 0.80) and genogroup C remained rare (n = 7/10 625 vs 17/13 488, p = 0.135). The proportion of serogroup positive isolates (i.e. those expressing capsule) decreased for genogroup W by 53.8% (95% CI –5.0 to 79.8, p = 0.016) and for genogroup Y by 30.1% (95% CI 8.9–46·3, p = 0.0025). Discussion: The UK MenACWY vaccination programme reduced carriage acquisition of genogroup and serogroup Y and W meningococci and sustained low levels of genogroup C carriage. These data support the use of quadrivalent MenACWY conjugate vaccine for indirect (herd) protection

Generation AI and family business: a perspective article

PurposeThis perspective article responds to the emergence of artificial intelligence (AI) as a significant opportunity for growth among family businesses, highlighting the need for future research to attain a clear picture of the next generation of family business successors.Design/methodology/approachThis is a literature review of current technology adoption within family businesses. The authors offer some research insight to spur critical thinking and discourse around the impact of AI on family business successors.FindingsFamily businesses are initially skeptical of AI technology. However, its use and adoption are crucial for the survival of the family business. To leverage this technology, the authors need to investigate the role of the family business successors as “Gen AI.”Originality/valueIt is challenging but necessary to develop policies and educational support for successors to ensure the survival of family businesses worldwide. The authors propose four key areas of future research.</p

COVID-legal study: neurosurgeon experience in Britain during the first phase of the COVID-19 pandemic - medico-legal considerations.

Introduction: The COVID-19 pandemic has resulted in a significant number of changes to elective and emergency neurosurgical practice.Materials and Methods: This paper reports the results of an online survey of Society of British Neurological Surgeons (SBNS) members undertaken between 10th and 24th of June 2020 regarding changes in consent practice in response to COVID-19, as well as the physical challenges experienced while operating under higher levels of personal protective equipment (PPE).Results: Despite the real and substantial risks associated with COVID-19, 23% of surgeons reported they were not made any changes to their usual consent process, and 54% of surgeons indicated that they made reference to COVID-19-associated risks in their written consent documentation. 93% of neurosurgeons reported physical difficulties operating using PPE; 62% reported visors/goggles fogging up, 55% experienced 'overheating', 62% reported fatigue, and 82% of surgeons reported difficulty communicating with the theatre staff.Conclusions: This survey highlights discrepancies in the consent practice between neurosurgeons which needs to be addressed at both local and national levels. The PPE being used in neurosurgical operations is not designed for use with specialist equipment (82% of respondents reported having to remove PPE to use the microscope) and the reported physical difficulties using PPE intraoperatively could significantly impact on both neurosurgeon performance and patient outcomes. This requires urgent attention by NHS procurement and management and should be urgently escalated to trust occupational health authorities as a workplace safety concern
