Study design Systematic review. Background Although degenerative cervical myelopathy (DCM) is the most prevalent spinal cord condition worldwide, the pathophysiology remains poorly understood. Our objective was to evaluate existing histological findings of DCM on cadaveric human spinal cord tissue and explore their consistency with animal models. Methods MEDLINE and Embase were systematically searched (CRD42021281462) for primary research reporting on histological findings of DCM in human cadaveric spinal cord tissue. Data was extracted using a piloted proforma. Risk of bias was assessed using Joanna Briggs Institute critical appraisal tools. Findings were compared to a systematic review of animal models (Ahkter et al. 2020 Front Neurosci 14). Results The search yielded 4127 unique records. After abstract and full-text screening, 19 were included in the final analysis, reporting on 150 autopsies (71% male) with an average age at death of 67.3 years. All findings were based on haematoxylin and eosin (H&E) staining. The most commonly reported grey matter findings included neuronal loss and cavity formation. The most commonly reported white matter finding was demyelination. Axon loss, gliosis, necrosis and Schwann cell proliferation were also reported. Findings were consistent amongst cervical spondylotic myelopathy and ossification of the posterior longitudinal ligament. Cavitation was notably more prevalent in human autopsies compared to animal models. Conclusion Few human spinal cord tissue studies have been performed. Neuronal loss, demyelination and cavitation were common findings. Investigating the biological basis of DCM is a critical research priority. Human spinal cord specimen may be an underutilised but complimentary approach.

Background The adequacy of personal protective equipment (PPE) and infection prevention and control (IPC) training in UK medical students and interim Foundation Year 1 (FiY1) doctors during the COVID-19 pandemic is unknown, as is its impact on COVID-19-related anxiety. Methods Cross-sectional, multi-centre study analysing self-reported adequacy of PPE and IPC training and correlation to a modified pandemic anxiety scale. Participants were current medical students and FiY1 doctors in the UK. Data were collected by an online survey. Results Participants reported that they received insufficient PPE information (43%) and IPC training (56%). Significantly, fewer participants identifying as women or BAME/mixed ethnicity reported receiving sufficient PPE information, compared with those identifying as men and White British/White Other, respectively. COVID-19-related anxiety was significantly higher in those without sufficient reported PPE or IPC training, in women compared with men, and in FiY1 doctors compared with medical students. Conclusions With medical students currently volunteering in and imminently returning to hospitals in an educational capacity, levels of self-reported PPE and IPC training are sub-optimal. Better training is paramount to avoid harm to patients and healthcare professionals and to reduce COVID-19-related anxiety among medical students and FiY1 doctors.

Objective To explore how social media could be utilised to influence an individual’s motivation to pursue a neurosurgical career, an emerging topic area. The focus of this study was on women interested in neurosurgery. Background Women are significantly under-represented in neurosurgery. 18% of all neurosurgeons – including 8% of consultants – are women. Most previous studies have used quantitative methods that are not best suited to gaining an in-depth understanding of the barriers that women face in pursuing a career in neurosurgery, or what would enable more women to go into the speciality. Method In this qualitative study, individual semi-structured interviews were conducted until data saturation was achieved. Participants were women pre-neurosurgical trainees. The interview data was examined through a thematic analysis involving open and axial coding. Results Thirty women participated in the study. Four overarching themes were identified: (1) mentorship, (2) testimony from other women doing neurosurgery, (3) social media as a means of increasing interest in neurosurgery as a career choice, and (4) real-life exposure to the speciality. Conclusions There is scope to further improve uptake of women into neurosurgical training in the UK. Motivations and barriers to women pursuing neurosurgery should be addressed openly through early experience, role models and mentorship. Social media can help facilitate these opportunities, disseminate information and inspiration, and has the potential to undo societal biases.

Cerebral small vessel disease (cSVD) in penetrating arteries is a major cause of age-related morbidity. Cellular senescence is a molecular process targeted by novel senolytic drugs. We quantified senescence in penetrating arteries and tested whether myocyte senescence was associated with cSVD. We immunolabeled subcortical white matter of older persons (age 80–96 years, n = 60) with minimal AD, using antibodies to 2 established senescence markers (H3K9me3, γH2AX) and a myocyte marker (hSMM). Within the walls of penetrating arteries (20–300 µm), we quantified senescence-associated heterochromatic foci (SAHF)-positive nuclei, cell density (nuclei/µm2), and sclerotic index (SI). Senescent-appearing mural cells were present in small arteries of all cases. cSVD cases exhibited a lower proportion of senescent-appearing cells and lower area fraction (AF%) of SAHF-positive nuclei compared to controls (p = 0.014, 0.016, respectively). cSVD severity and SI both correlated negatively with AF% (p = 0.013, 0.002, respectively). Mural cell density was lower (p

Highlights • Analysing the benefits of Wide-Awake Local Anaesthetic, No Tourniquet in upper limb surgery. • Over 40 WALANT papers published since the last systematic review. • Systematic review compliant with the PRISMA guidelines., Introduction Wide Awake Local Anaesthetic No Tourniquet (WALANT) technique has been developed to eliminate tourniquet pain during upper limb and hand surgery whilst also improving utilisation of operating theatre time and inpatient stay, however inconclusive data still limits the techniques uptake. Here presents a protocol for a systematic review to collate findings to produce conclusive data on efficacy of WALANT. Methods This systematic review will be registered a priori. All study designs defined by the Oxford Centre for Evidence-Based Medicine will be included in the search. “WALANT” in “upper limb” and “hand” surgery will be investigated as per the devised search strategy. 18 electronic databases will be searched, including PubMed, Medline and Embase in addition to a Grey literature search. Two independent teams of 3 researchers will screen all relevant titles, abstracts and subsequent full texts for suitability. Data will be extrapolated and entered into a preformatted database for analysis. Ethics and dissemination This systematic review will be published in a peer-reviewed journal and presented at both national and international conferences within the field of plastic and orthopaedic surgery. This review aims to inform surgical practice and policy.
